Patent No. 5992864 JP 2020-128699 A

However, the water stop device disclosed in Patent Document 1 requires the presence of a door to which the water stop plate is attached, and it is not possible to block an opening where there is no door to prevent water from passing through.
In addition, the water-stopping device disclosed in Patent Document 2 has a width of a water-stopping member that is slightly larger than the opening width of the door frame, and when the water-stopping member is installed in the door frame, it is installed in the door frame in a pressed-in state while being compressed slightly in the width direction, and also has a width of the water-stopping member that is equal to or smaller than the opening width of the door frame, and when the water-stopping member is installed, it is installed so that a first part of the water-stopping member is sandwiched between the door and the doorstop of the door frame.
However, in the water-stopping device disclosed in Patent Document 2, when the water-stopping member is installed in the door frame in a pressed-in state while being slightly compressed in the width direction, the door frame and the water-stopping member may be damaged. Also, when the first part of the water-stopping member is installed so as to be sandwiched between the door and the door stop of the door frame, the presence of a door to support the water-stop plate is essential, and it is not possible to block the opening where there is no door to prevent water from passing through.
Furthermore, the water-stopping device disclosed in Patent Document 1 is configured so that a watertightness maintaining means (seal) is provided between the plate surface of the waterstop plate and the door stop of the door frame, and the water-stopping device disclosed in Patent Document 2 is configured so that a watertightness maintaining means (gasket (sealing material)) is provided between the first part and each door stop. Therefore, in the water-stopping devices disclosed in Patent Documents 1 and 2, two components, the watertightness maintaining means and the plate material, which are not actually present, are present on the outside of the door stop of the door frame, and this makes it impossible to close the door as it should, which may cause problems with the door's original functions, such as opening and closing the door and locking the door.
In other words, the water stopping devices disclosed in Patent Documents 1 and 2 had the problem that they were unable to block openings where no doors existed to prevent water from passing through, and there was a risk that the original function of the door would be impaired.

The present invention aims to solve the above problems by providing a water stop device that can block an opening even when there is no door, preventing the passage of water, and that is unlikely to damage the door frame and is unlikely to impair the original function of the door when installed to block the inner opening (opening) of a door frame to which a door is attached so as to be able to open and close.

A waterstopping device according to a first aspect of the present invention is a waterstopping device for blocking an opening having a left surface, a right surface, and a bottom surface to prevent water from passing through the opening, the waterstopping device comprising: a waterstopping wall; a left-side watertightness maintaining means provided on at least one of the left end surface of the waterstopping wall and the left surface of the opening in order to maintain watertightness between the left end surface of the waterstopping wall and the left surface of the opening; a right-side watertightness maintaining means provided on at least one of the right end surface of the waterstopping wall and the right surface of the opening in order to maintain watertightness between the right end surface of the waterstopping wall and the right surface of the opening; and a lower-side watertightness maintaining means provided on at least one of the lower end surface of the waterstopping wall and the bottom surface of the opening in order to maintain watertightness between the bottom end surface of the waterstopping wall and the bottom surface of the opening, the opening being an inner opening of a door frame provided in an architectural structure and being provided so as to extend beyond the left end surface of the waterstopping wall. and a right side locking portion that is provided so as to extend from the right end face of the waterstop wall and locks onto the right doorstop surface of the inner opening of the door frame, wherein the left side locking portion locks onto the left doorstop surface, and the left side watertightness maintaining means provided on the left end face of the waterstop wall maintains watertightness between the left side of the inner opening of the door frame, and the right side locking portion locks onto the right doorstop surface, and the right side watertightness maintaining means provided on the right end face of the waterstop wall maintains watertightness between the right side of the inner opening of the door frame. Therefore, it is possible to provide a waterstop device that can block an opening without a door to prevent the passage of water, and that is less likely to damage the door frame and less likely to impair the original function of the door when installed to block the inner opening of a door frame to which a door is attached so as to be able to open and close. Furthermore, when the water stop wall is subjected to water pressure, for example from the outdoors, the left and right retaining portions engage with the door stop surface of the door frame, thereby preventing the water stop device from collapsing, for example, toward the indoor side.
In addition, the water-stopping device of claim 2 is characterized in that it is provided with a lower engagement portion that extends from the lower end surface of the water-stopping wall and engages with the lower door-stopping surface of the inner opening of the door frame , and the lower engagement portion engages with the lower door-stopping surface, and the lower watertightness maintaining means provided on the lower end surface of the water-stopping wall maintains watertightness between the lower surface of the inner opening of the door frame.Therefore, when the water-stopping wall is subjected to water pressure, for example from the outdoors, the left engagement portion, the right engagement portion and the lower engagement portion engage with the door-stopping surface of the door frame, thereby preventing the water-stopping device from collapsing, for example, toward the indoor side.
In addition, the water-stopping device of claims 3 to 21 of the present invention is a water-stopping device for blocking an opening having a left side, a right side, and a bottom side to prevent water from passing through the opening, and in addition to a configuration including a water-stopping wall, a left-side watertightness maintaining means provided on at least one of the left end face of the water-stopping wall and the left side of the opening to maintain watertightness between the left end face of the water-stopping wall and the left side of the opening, a right-side watertightness maintaining means provided on at least one of the right end face of the water-stopping wall and the right side of the opening to maintain watertightness between the right end face of the water-stopping wall and the right side of the opening, and a lower watertightness maintaining means provided on at least one of the lower end face of the water-stopping wall and the bottom side of the opening to maintain watertightness between the lower end face of the water-stopping wall and the bottom side of the opening, the water-stopping device is further provided with the following configurations.

Alternatively, after forming the plates by developing each of these parts, the boundaries of each part may be folded. In this case, at least the boundary between the lower plate part 2d and the left plate part 2b and the boundary between the lower plate part 2d and the right plate part 2c are subjected to a joining process by welding or other joining means, or a filling process S (see FIG. 6) in which a filler such as a sealant is filled therein, or the joining process portion is subjected to a filling process S after the joining process.

The left-side watertightness maintaining means 3 is a member provided on the left end face 22 of the water-stopping wall 2 and comes into contact with the left face 12 of the inner opening 11 of the door frame 10 to maintain watertightness between the left face 12.

The left end face 22 of the waterstop wall 2, which serves as the mounting surface to which the left-side watertightness maintaining means 3 is attached, is formed by the outer plate surface of the left plate portion 2b, and the mounting surface of the flat left-side watertightness maintaining means 3, which has a plate surface that serves as the mounting surface and is slightly smaller than the left end face 22, is attached with an adhesive or the like to the left end face 22 of the waterstop wall 2, which serves as the mounting surface.
The right end surface 23 of the watertightness maintaining means 4 on the right side, which serves as the mounting surface, is formed by the outer plate surface of the right plate portion 2c, and the mounting surface of the flat right side watertightness maintaining means 4 having a plate surface that is slightly smaller than the right end surface 23, for example, is attached with an adhesive or the like to the right end surface 23 of the watertightness maintaining wall 2, which serves as the mounting surface.

Furthermore, the lower end surface of the left-side watertightness maintaining means 3 and the lower end surface of the right-side watertightness maintaining means 4 are configured to come into contact with the underside 14 of the inner opening 11 of the door frame 10 to maintain the watertightness performance between said underside 14, and the left end surface of the lower watertightness maintaining means 5 and the left-side watertightness maintaining means 3 are arranged so as to be in close contact with each other, and the right end surface of the lower watertightness maintaining means 5 and the right-side watertightness maintaining means 4 are arranged so as to be in close contact with each other.
Alternatively, the lower end surface of the lower watertightness maintaining means 5 is configured to come into contact with the underside 14 of the inner opening 11 of the door frame 10 to maintain watertightness performance between said underside 14, and the lower end surface of the left side watertightness maintaining means 3 and the lower watertightness maintaining means 5 are arranged so as to be in close contact with each other, and the lower end surface of the right side watertightness maintaining means 4 and the lower watertightness maintaining means 5 are arranged so as to be in close contact with each other.

The watertightness maintaining means 3, 4, and 5 may be, for example, a rubber sealant such as EPDM rubber sponge (ethylene propylene rubber) or a sealant with water swelling properties, but sealants made of other materials may also be used.

The water-stopping device 1 of embodiment 1 is installed so that the left-side engagement portion 6 engages with the left doorstop surface 16, and the left-side watertightness maintaining means 3 provided on the left end surface 22 of the water-stopping wall 2 maintains watertightness between the left surface 12 of the door frame 10, and the right-side engagement portion 7 engages with the right doorstop surface 17, and the right-side watertightness maintaining means 4 provided on the right end surface 23 of the water-stopping wall 2 maintains watertightness between the right surface 13 of the door frame 10, and further, the lower engagement portion 8 engages with the lower doorstop surface 18, and the lower watertightness maintaining means 5 provided on the lower end surface 24 of the water-stopping wall 2 maintains watertightness between the lower surface 14 of the door frame 10.
In the door frame 10 illustrated in embodiment 1, the left side 12, right side 13, bottom side 14, and top side 15 of the inner opening 11 of the door frame 10 are rear (indoor) sides of the door stop surfaces 16, 17, 18, and 19.

According to the water stop device 1 of the first embodiment, the left-right width of the water stop device 1, i.e., the dimension of the gap between the left outer surface (outer plate surface) of the left watertightness maintaining means 3 provided on the left end surface 22 of the water stop wall 2 and the right outer surface (outer plate surface) of the right watertightness maintaining means 4 provided on the right end surface 23 of the water stop wall 2, is formed to be slightly larger than the left-right width of the opening of the door frame 10, i.e., the dimension of the gap between the left surface 12 and the right surface 13 of the inner opening 11 of the door frame 10. The water-stopping device 1 is attached in a fixed state to the left surface 12, right surface 13, bottom surface 14 and top surface 15 of the inner opening 11 of the door frame 10 by tightly contacting the left outer surface of the left watertightness maintaining means 3 provided on the right end surface 23 of the water-stopping wall 2 with the left surface 12 of the door frame 10, tightly contacting the right outer surface of the right watertightness maintaining means 4 provided on the right end surface 23 of the water-stopping wall 2 with the right surface 13 of the door frame 10, and tightly contacting the lower outer surface of the lower watertightness maintaining means 5 provided on the bottom end surface 24 of the water-stopping wall 2 with the bottom surface 14 of the door frame 10.
Therefore, when water W rushes in from the front side (outdoor side) of the water-stopping device 1 fixedly attached to the door frame 10, the watertightness maintaining means 3, 4, and 5 can prevent the water W from entering the rear side (indoor side) of the water-stopping device 1.

In addition, when the wall panel portion 2a of the water-stopping wall 2 is subjected to water pressure from the front side (outdoor side) of the water-stopping device 1, the left side locking portion 6, the right side locking portion 7, and the lower side locking portion 8 lock onto the door stop surfaces 16, 17, and 18 of the door frame 10, thereby preventing the water-stopping device 1 from collapsing to the rear side (indoor side).
As shown in Fig. 3(b), after the water stop device 1 is fixedly attached to the inner opening 11 of the door frame 10, when the door 9 is closed, water W can enter the box-shaped space B of the water stop wall 2 through the gap L between the lower end surface 9a of the door 9 and the drain surface 14F located in front of the lower surface 14 of the door frame 10 opposite the lower end surface 9a. In the water stop device 1 according to the first embodiment, when flooded, the flow of water W stops when the head height of the front side (outdoor side) of the door 9 becomes the same as the head height of the water in the box-shaped space B of the water stop wall 2. In this case, the door 9 is in the same state as when it is submerged in water, and the door 9 can be easily opened, so that it is possible to open the door 9 and move to the outdoors.

In addition, when a sealant having water swelling properties is used as the watertightness maintaining means 3, 4, and 5, after the waterstop device 1 is attached to the door frame 10, the sealant having water swelling properties that constitutes the watertightness maintaining means 3, 4, and 5 is moistened, causing the sealant to expand, improving the watertightness between the left side 12, right side 13, and bottom side 14 of the inner opening 11 of the door frame 10.

According to the water-stopping device 1 of embodiment 1, the door 9 is attached so as to block the inner opening (opening) 11 of the door frame 10 to which the door 9 is attached so as to be capable of being opened and closed, thereby preventing water from entering the rear side (indoor side) of the water-stopping device 1 by the water-tightness maintaining means 3, 4, and 5.
In addition, when the water-stopping device 1 is attached to the inner opening 11 of the door frame 10, the watertightness maintaining means 3, 4, and 5, which are made of elastic sealing material, come into contact with the left surface 12, right surface 13, and bottom surface 14 of the inner opening 11 of the door frame 10, so that the door frame 10 is less likely to be damaged.
In addition, since the left side locking portion 6, the right side locking portion 7, and the lower locking portion 8 are in direct contact with the door abutment surfaces 16, 17, and 18 of the door frame 10 and there are no components between the left side locking portion 6, the left side locking portion 6, the right side locking portion 7, and the lower locking portion 8 and the door abutment surfaces 16, 17, and 18 of the door frame 10, there is less risk that the door 9 will be unable to be placed in its correct closed state, which will cause problems with the door's original functions such as opening and closing and locking operations, and a water stop device 1 that is less likely to impair the original functions of the door 9 can be provided.
In addition, even in the case of an opening where there is no door 9, a water-stopping device 1 can be provided that can block the opening and prevent water from passing through by installing the watertightness maintaining means 3, 4, 5 of the water-stopping device 1 so as to maintain watertightness between the left surface 12, right surface 13, and bottom surface 14 of the opening.

EMBODIMENT 2
In embodiment 1, a water-stopping device 1 is exemplified in which the left side watertightness maintaining means 3, the right side watertightness maintaining means 4, and the lower side watertightness maintaining means 5, which are constructed separately, are attached to the left end face 22, right end face 23, and lower end face 24 of the water-stopping wall 2. However, the water-stopping device 1 may be configured in such a way that the left side watertightness maintaining means 3, the right side watertightness maintaining means 4, and the lower side watertightness maintaining means 5 are integrally formed as watertightness maintaining means, and are attached to the left end face 22, right end face 23, and lower end face 24 of the water-stopping wall 2.
Similarly, in each of the embodiments described below, the left side watertightness maintaining means 3, the right side watertightness maintaining means 4, and the lower side watertightness maintaining means 5 may be configured separately or as an integrated unit.

EMBODIMENT 3
In the water-stopping device 1 of embodiment 1, a configuration has been exemplified in which watertightness maintaining means 3, 4, and 5 made of flat sealing material are attached to the left end face 22, right end face 23, and bottom end face 24 of the water-stopping wall 2, which is the mounting surface. However, in the water-stopping device 1 of embodiment 3, as shown in Figure 4, the watertightness maintaining means 3, 4, and 5 are composed of sealing material attached to the left end face 22, right end face 23, and bottom end face 24 of the water-stopping wall 2, which is the mounting surface, and the sealing material constituting the watertightness maintaining means 3, 4, and 5 is formed so that the thickness dimension from the mounting surface of the water-stopping wall 2 to which the sealing material is attached gradually increases from the tip side to the end side when the water-stopping wall 2 is inserted into the inner opening (opening) 11 from the front side (outdoor side).
As shown in FIG. 4, the tip side described in the third embodiment corresponds to the rear side (indoor side) of the opening, and the end side corresponds to the front side (outdoor side) of the opening.

For example, the sealing material constituting the watertightness maintaining means 3, 4, 5 is configured so that the surfaces that come into contact with the left surface 12, right surface 13 and bottom surface 14 of the inner opening 11 of the door frame 10 are formed into inclined surfaces so that the thickness dimension from the left end surface 22, right end surface 23 and bottom end surface 24, which are the mounting surfaces to which the sealing material constituting the watertightness maintaining means 3, 4, 5 is attached, gradually increases from the tip side to the end side when the waterstop wall 2 is inserted into the inner opening (opening) 11 from the front side (outdoor side).
FIG. 4(a) shows a watertightness maintaining means 5 in which the surface that comes into contact with the underside 14 of the inner opening 11 of the door frame 10 is formed into an inclined surface 5a so that the thickness dimension from the lower end surface 24 of the water stopping wall 2, which is the mounting surface, gradually increases from the tip side toward the end side described above.
Figure 4 (b) shows the left-side watertightness maintaining means 3, in which the surface that comes into contact with the left surface 12 of the inner opening 11 of the door frame 10 is formed into an inclined surface 3a so that the thickness dimension from the left end surface 22 of the waterstop wall 2, which is the mounting surface, gradually becomes thicker from the tip side toward the end side described above.
Similarly, although not shown, the watertightness maintaining means 4 on the right side is formed so that the surface that comes into contact with the right surface 13 of the inner opening 11 of the door frame 10 is formed as an inclined surface so that the thickness dimension from the right end surface 23 of the waterstop wall 2, which is the mounting surface, gradually increases from the tip side toward the end side as described above.

As shown in Figures 4(c) and (d), the sealing material constituting the watertightness maintaining means 3, 4, 5 is configured so that the thickness dimension from the left end face 22, right end face 23 and bottom end face 24, which are the mounting faces to which the sealing material constituting the watertightness maintaining means 3, 4, 5 is attached, gradually increases from the leading end side to the trailing end side when the waterstop wall 2 is inserted into the inner opening (opening) 11 from the front side (outdoor side). A plurality of sickle-shaped protrusions are provided at intervals along the fore-and-aft direction (tip-end direction) so that the protrusions protrude diagonally rearward (end side) from a plane that is an opposing face parallel to the flat mounting surface attached to the mounting face, and the protrusions provided closer to the rear (end side) have a larger protrusion amount and size.
FIG. 4( c ) shows the watertightness maintaining means 5 on the left side of the configuration in which a plurality of sickle-shaped protrusions 5 d are provided at intervals along the front-to-rear direction (end-to-end direction) protruding diagonally rearward (end side) from a plane that is an opposing surface 5 c parallel to a flat mounting surface 5 b attached to the lower end surface 24 so that the thickness dimension from the lower end surface 24, which is the mounting surface to which the watertightness maintaining means 5 is attached, gradually increases from the tip side toward the end side as described above, and the protrusion amount and size of the protrusions 5 d provided closer to the rear (end side) are greater.
FIG. 4( d ) shows the lower watertightness maintaining means 3 configured such that the thickness dimension from the left end face 22, which is the mounting surface to which the watertightness maintaining means 3 is attached, gradually increases from the tip side toward the end side as described above. A plurality of sickle-shaped protrusions 3 d are provided at intervals along the front-to-rear direction (tip-end direction) protruding diagonally rearward (end side) from a plane that is an opposing surface 3 c that is parallel to the planar mounting surface 3 b attached to the left end face 22, and the protrusion amount and size of the protrusions 3 d provided closer to the rear (end side) are greater.

The water stop device 1 according to embodiment 3, which is equipped with watertightness maintaining means 3, 4, and 5 configured so that the thickness dimension from the mounting surface gradually increases from the tip side toward the end side, facilitates attachment and detachment to and from the inner opening 11 of the door frame 10, and improves the watertightness maintaining function and support function when the water stop device 1 is attached to the door frame 10. In other words, it is possible to provide a water stop device 1 with excellent watertightness maintaining function and support function.

EMBODIMENT 4
As shown in Figure 5, in the water-stopping device 1 of embodiment 3, the sealing material constituting the watertightness maintaining means 3, 4, 5 has a mounting portion 30A having a mounting surface 30a attached to the mounting surface (left end surface 22, right end surface 23, bottom end surface 24) of the water-stopping wall 2, and a folded-back portion 30B extending from the mounting portion 30A and folded back to have an outer surface 30b facing the surface (left surface 12, right surface 13, bottom surface 14) of the inner opening 11 of the door frame 10, and is configured to have a groove 30 formed by a facing surface 30c of the mounting portion 30A and a facing surface 30d of the folded-back portion 30B which face each other, and a surface 30e of the boundary portion between the mounting portion 30A and the folded-back portion 30B which extends from these facing surfaces 30c, 30d.
Furthermore, the watertightness maintaining means 3, 4, 5 is configured to have a pressing means 31 which is fitted into the groove 30 of the watertightness maintaining means to press the outer surface 30b of the folded portion 30B of the watertightness maintaining means 3, 4, 5 against the surface of the inner opening 11 of the door frame 10.

The pressing means 31 has a cross-sectional shape larger than the cross-sectional shape of the groove 30 of the watertightness maintaining means 3, 4, 5, and includes a reference surface 32 that contacts the opposing surface 30c of the mounting portion 30A, and a pressing surface 33 that contacts the opposing surface 30d of the folded portion 30B to press the outer surface 30b of the folded portion 30B against the surface of the inner opening 11 of the door frame 10, for example, a wedge-like fitting member that fits into the groove 30.

According to the water stop device 1 of the fourth embodiment, the water stop device 1 is installed so that the outer surfaces of the watertightness maintaining means 3, 4, 5 face each surface (left surface 12, right end surface 13, bottom end surface 14) of the inner opening 11 of the door frame 10, and the pressing means 31 is inserted into the groove 30 of the watertightness maintaining means 3, 4, 5 with the locking portions 6, 7, 8 in contact with the door stop surfaces 16, 17, 18. This causes the outer surface 30b of the folded portion 30B of the watertightness maintaining means 3, 4, 5 to be pressed against each surface of the inner opening 11 of the door frame 10, and the water stop device 1 is supported against each surface of the inner opening 11 of the door frame 10, while maintaining good watertightness between the watertightness maintaining means 3, 4, 5 and each surface of the inner opening 11.

In Figure 5, an example is shown in which a watertightness maintaining means formed integrally with a left-side watertightness maintaining means 3, a right-side watertightness maintaining means 4, and a lower-side watertightness maintaining means 5 is attached to the left end face 22, the right end face 23, and the lower end face 24 of the waterstop wall 2, and the pressing means 31 is made up of a linear groove corresponding pressing means 31A for the portion where the groove 30 extends in a straight line and a corner groove corresponding pressing means 31B for the portion where the groove 30 extends in an L-shape.
In this way, when an integrated watertightness maintaining means is used and a configuration is used in which a linear groove corresponding pressing means 31A and a corner groove corresponding pressing means 31B are used as the pressing means 31, the use of the corner groove corresponding pressing means 31B makes it possible to maintain good watertightness performance between the watertightness maintaining means and the inner corner portion which is the boundary between the left surface 12 and the bottom surface 14 of the door frame 10, as well as watertightness between the watertightness maintaining means and the inner corner portion which is the boundary between the right surface 13 and the bottom surface 14 of the door frame 10.

In the fourth embodiment, a configuration may be used in which separate watertightness maintaining means 3 on the left side, watertightness maintaining means 4 on the right side, and watertightness maintaining means 5 on the lower side are used. In this case, as the pressing means, it is sufficient to use the linear groove corresponding pressing means 31A, and it is not necessary to use the corner groove corresponding pressing means 31B.
Incidentally, it is preferable that the pressing means 31 is provided with a handle 34, as in the linear groove corresponding pressing means 31A shown in Fig. 5. When the handle 34 is provided, the pressing means 31 can be removed from the grooves 30 of the watertightness maintaining means 3, 4, 5 by holding the handle 34, and the removal work can be easily performed. Also, in Fig. 5, the corner groove corresponding pressing means 31B without the handle 34 is shown, but it is preferable that the corner groove corresponding pressing means 31B also has a handle 34.

The water stop device 1 according to the fourth embodiment can be easily attached to and detached from the inner opening 11 of the door frame 10, and the watertightness maintaining function and the support function are improved when the water stop device 1 is attached to the door frame 10. In other words, a water stop device 1 with excellent watertightness maintaining function and support function can be provided.

EMBODIMENT 5
As shown in Figure 6, the water-stopping device 1 of embodiment 5 is configured to have a support mechanism 40 on at least one of the left and right sides of the upper part of the water-stopping wall 2 in the water-stopping device 1 of embodiments 1 to 4, for supporting the water-stopping wall 2 on the left and right surfaces 12, 13 of the inner opening 11 of the door frame 10.

For example, as shown in FIG. 6, the support mechanism 40 is configured to include a pressing body 41 that is movable in a direction perpendicular to the left and right faces 12, 13 of the inner opening of the door frame, a transport means 42 for moving the pressing body 41 in a direction perpendicular to the left and right faces 12, 13 of the inner opening 11 of the door frame 10, and a reaction force transmission means 43 for transmitting a reaction force to the water blocking wall 2 when the pressing body 41 presses against the left face 12 or right face 13 of the inner opening 11 of the door frame 10.

The transfer means 42 is composed of a female threaded hole 45 formed in a support piece 44 that is extended upward from the left end of the upper plate portion 2e of the water-stopping wall 2, and a screw 46 that is screwed into the female threaded hole 45 and is configured to be movable in the left-right direction, with a pressing body 41 provided at the left end, which is the tip of the screw 46 screwed into the female threaded hole 45, and an operating handle 46a provided at the right end, which is the terminal end of the screw 46 screwed into the female threaded hole 45.
Similar to the left side of the water blocking wall 2, the pressing body 41 is configured to include a plate portion 47 having a left plate portion 47a and a left locking portion 47b, and a support body 48 provided on the outer surface of the left plate portion 47a.
The support 48 is preferably formed from a material harder than the above-mentioned sealing material, such as hard rubber, which has a relatively high rigidity and is less likely to scratch the surface.
The reaction force transmission means 43 is constituted by the above-mentioned screw 46 and a support piece 44 provided to extend from the water blocking wall 2 and equipped with a female threaded hole 45 into which the screw 46 is screwed.

According to the water-stopping device 1 of embodiment 5, by operating the operating handle 46a, the pressing body 41 presses the left surface 12 of the inner opening 11 of the door frame 10, and the watertightness maintaining means 4 on the right side of the water-stopping wall 2 is pressed against the right surface 13 of the inner opening 11 of the door frame 10 due to the reaction force when the pressing body 41 presses the left surface 12 of the inner opening 11 of the door frame 10, or the pressing body 41 presses the right surface 13 of the inner opening 11 of the door frame 10, and the watertightness maintaining means 3 on the left side of the water-stopping wall 2 is pressed against the left surface 12 of the inner opening 11 of the door frame 10 due to the reaction force when the pressing body 41 presses the right surface 13 of the inner opening 11 of the door frame 10, so that the water-stopping wall 2 is supported by the left and right surfaces 12, 13 of the inner opening 11 of the door frame 10, thereby improving the support function for supporting the water-stopping wall 2. That is, the support function of the water stop device 1 is improved when it is attached to the inner opening 11 of the door frame 10. In other words, it is possible to provide a water stop device 1 with excellent support function.

The water stopping device 1 according to the fifth embodiment may be configured to include the above-mentioned support mechanisms 40 on both the left and right sides of the upper portion of the water stopping wall 2 .
In this case, the water blocking wall 2 is supported on the left and right surfaces 12, 13 of the inner opening 11 of the door frame 10 via the left and right pressing bodies 41, 41.

EMBODIMENT 6
In the case of the water-stopping device 1 of embodiment 5, if the pressing body 41 of the support mechanism 40 presses the surface of the inner opening 11 of the door frame 10 too hard in order to enhance the supporting function for supporting the water-stopping wall 2, it may become impossible to maintain the watertight performance between the watertightness maintaining means 3, 4 and the left and right surfaces 12, 13 of the inner opening 11 of the door frame 10.
Therefore, the water-stopping device 1 according to the sixth embodiment is configured to improve the support function for supporting the water-stopping wall 2 and also improve the function of maintaining watertightness.

That is, as shown in Fig. 7, the water stopping device 1 according to the sixth embodiment includes a support mechanism 50 connected to an upper portion of the water stopping wall 2, and the support mechanism 50 includes a horizontal support mechanism 50A for supporting the water stopping wall 2 on the left and right surfaces 12, 13 of the inner opening 11 of the door frame 10, and a vertical support mechanism 50B for supporting the water stopping wall on the lower surface of the inner opening of the door frame. Furthermore, when the water stopping wall 2 is supported on the left and right surfaces 12, 13 of the inner opening 11 of the door frame 10 by the horizontal support mechanism 50A, the watertightness maintaining means 3 on the left side and the watertightness maintaining means 4 on the right side of the water stopping wall 2 that are not pressed against the surface of the inner opening 11 of the door frame 10, for example, the watertightness maintaining means 3 on the left side in Fig. 7(a) , has the same configuration as that described in the fourth embodiment (Fig. 5).
In other words, when the water blocking wall 2 is supported on the left and right surfaces 12, 13 of the inner opening 11 of the door frame 10 by the horizontal support mechanism 50A, the watertightness maintaining means 3 on the left side of the water blocking wall 2 and the watertightness maintaining means 4 on the right side thereof that are not pressed against the surface of the inner opening 11 of the door frame 10 are, for example, the mounting surfaces 30 attached to the mounting surfaces (left end surface 22, right end surface 23, bottom end surface 24) of the water blocking wall 2, similar to the watertightness maintaining means 3, 4, 5 of FIG. a) of the mounting portion 30A having a groove 30; and, extending from the mounting portion 30A and folded back to have an outer surface 30b facing the surface of the inner opening 11 of the door frame 10. The groove 30 is formed by a facing surface 30c of the mounting portion 30A and a facing surface 30d of the folded back portion 30B which face each other, and a surface 30e of the boundary between the mounting portion 30A and the folded back portion 30B which extends from the facing surfaces 30c, 30d.
In addition, the door frame 10 is provided with a pressing means 31C (see FIG. 7(b)) having a configuration similar to the linear groove corresponding pressing means 31A described above, which is fitted into the groove 30 of the watertightness maintaining means and presses the outer surface 30b of the folded portion 30B of the watertightness maintaining means against the surface of the inner opening 11 of the door frame 10.

Furthermore, when the waterstop wall 2 is supported on the left and right surfaces 12, 13 of the inner opening 11 of the door frame 10 by the horizontal support mechanism 50A, if the watertightness maintaining means 3 on the left side and the watertightness maintaining means 4 on the right side of the waterstop wall 2 that is not pressed against the surface of the inner opening 11 of the door frame 10 is, for example, the left side watertightness maintaining means 3 shown in Figure 7(a), the groove 30 may be configured as shown in Figure 7(b) to be formed by a V-shaped or U-shaped cross-sectional groove 30 formed by a V-shaped or U-shaped cross-sectional leaf spring 35.
In other words, the watertightness maintaining means 3 and the right-side watertightness maintaining means 4 that are not pressed against the surface of the inner opening 11 of the door frame 10 may be a watertightness maintaining means configured by combining a leaf spring 35 and a sealing material 36.
In FIG. 7B, the same or corresponding parts as those explained in FIG. 5 are designated by the same reference numerals and detailed explanations thereof will be omitted.
In this case, the mounting portion 30A is composed of one plate portion 35a of the V-shape or U-shape of the leaf spring 35 having a mounting surface 30a attached to the surface of the water-stopping wall 2, and the folded-back portion 30B is composed of the other plate portion 35b of the V-shape or U-shape of the leaf spring 35 extending from the mounting portion 30A and folded back, and a sealing material 36 attached to the outer plate surface of the other plate portion 35b and having an outer surface 30b facing the surface of the inner opening 11 of the door frame 10.
The seal material 36 may be the same as the watertightness maintaining means 3, 4, and 5 described in the first embodiment.
In addition, the leaf spring 35 is formed, for example, from a metal, a synthetic resin, etc., and is configured so that when force is applied to the plate portion on one side of the V or U shape and the plate portion on the other side, the elasticity of the bent portion, which is the boundary between the plate portion on one side of the V or U shape and the plate portion on the other side, urges the plate portion on one side of the V or U shape and the plate portion on the other side in a direction away from each other.

The horizontal support mechanism 50A is configured to include an expandable member 51 that is configured to be able to expand and contract its length in a direction perpendicular to the left and right faces 12, 13 of the inner opening 11 of the door frame 10, and a reaction force transmission means 52.

In this case, the expandable member 51 is configured, for example, to include a fixed length member 51A having one end arranged to contact either the left surface 12 or the right surface 13 of the inner opening 11 of the door frame 10, and a pressing mechanism 51B provided on the other end side of the fixed length member 51A so as to be movable in a direction perpendicular to the left and right surfaces 12, 13 of the inner opening 11 of the door frame 10.
The fixed length member 51A is formed of a pipe material, such as a metal pipe having a rectangular cross section.
The pressing mechanism 51B has a similar structure to the support mechanism 40 described above.
For example, as shown in FIG. 7(a), the pressing mechanism 51B is configured to include a support piece 51a extending upward from the other end side of the fixed length member 51A, a female threaded hole 51b formed in the support piece 51a, a screw 51c screwed into the female threaded hole 51b and configured to be movable in the left-right direction, and a pressing body 51d provided at the tip of the screw 51c screwed into the female threaded hole 51b and contacting either the left or right surface 12, 13 of the inner opening 11 of the door frame 10.
The pressing body 51d is preferably made of a material harder than the sealing material, such as hard rubber, which has a relatively high rigidity and is less likely to scratch the surface.
Furthermore, of both ends of the fixed length member 51A, at least the end opposite the side where the pressing mechanism 51B is provided is provided with a contact portion 51f that contacts the other of the left and right surfaces 12, 13 of the inner opening 11 of the door frame 10, and it is preferable that the contact portion 51f, like the pressing body 51d, is formed from a material that is harder than the sealing material, such as hard rubber, which has relatively high rigidity and is less likely to scratch the surface.

The reaction force transmission means 52 is a means that functions to transmit the reaction force to the water stop wall 2 when the pressing body 51d presses either the left surface 12 or the right surface 13 of the inner opening 11 of the door frame 10, and is composed of, for example, a bolt 53 and a nut 54 that connect the expandable member 51 and the upper plate portion 2e of the water stop wall 2 in a fixed state.

The vertical support mechanism 50B comprises the aforementioned expandable member 51 which is attached so as to brace against the left and right surfaces 12, 13 of the inner opening 11 of the door frame 10, and a pressing mechanism 55 which is arranged to be movable vertically relative to the fixed length member 51A of the expandable member 51.
For example, as shown in FIG. 7(a), the pressing mechanism 55 is configured to include a female threaded hole 55a formed in the fixed length member 51A of the aforementioned expandable member 51, a screw 55b that is screwed into the female threaded hole 55a and configured to be movable in the vertical direction, and a pressing body 55c that is provided at the lower end, which is the tip of the screw 55b screwed into the female threaded hole 55a, and that contacts the upper surface of the upper plate portion 2e of the water-stopping wall 2.

According to the waterstop device 1 of the sixth embodiment, after the waterstop device 1 is installed so that the outer surfaces of the watertightness maintaining means 3, 4, and 5 face each surface of the inner opening 11 of the door frame 10, the horizontal support mechanism 50A is first operated. For example, by operating the horizontal support mechanism 50A shown in FIG. 7(a), the expandable member 51 is braced against the left and right surfaces 12, 13 of the inner opening 11 of the door frame 10, and the waterstop wall 2 is supported by the left and right surfaces 12, 13 of the inner opening 11 of the door frame 10.
Furthermore, when operating the horizontal support mechanism 50A, the bolts 53 and nuts 54 constituting the reaction force transmission means 52 are tightened to connect and fix the expandable member 51 and the water blocking wall 2.
Next, the bolt 53 and the nut 54 are loosened, and the vertical support mechanism 50B is operated. That is, the screw 55b is turned to move the pressing body 55c downward, and the water blocking wall 2 is pressed downward and moved, whereby the water blocking wall 2 is supported on the lower surface 14 of the inner opening 11 of the door frame 10.
Thereafter, the pressing means 31C is inserted into the groove 30 of the watertightness maintaining means 3 on the left side as shown in Figure 7, for example, so that the outer surface 30b of the folded portion 30B of the watertightness maintaining means 3 is pressed against the left surface 12 of the inner opening 11 of the door frame 10 (see Figure 7 (b)).
As a result of the above, the water-stopping device 1 is supported on each surface 12, 13, 14 of the inner opening 11 of the door frame 10, and the watertightness performance between the watertightness maintaining means 3, 4, 5 and each surface 12, 13, 14 of the inner opening 11 is maintained.

That is, the water stopping device 1 according to the sixth embodiment is provided with a support mechanism 50 having a horizontal support mechanism 50A and a vertical pressing mechanism 50B instead of the support mechanism 40 of the fifth embodiment, and is provided with a watertightness maintaining means having a similar structure to the watertightness maintaining means shown in the fourth embodiment as the watertightness maintaining member on the side where the watertightness performance between the watertightness maintaining member and the surface is weaker, and is further configured with a pressing mechanism 31C which is fitted into the groove 30 of the watertightness maintaining means and presses the outer surface 30b of the folded portion 30B against the surface of the inner opening 11 of the door frame 10, thereby facilitating the attachment and detachment operation to and from the inner opening 11 of the door frame 10, and further improving the watertightness maintaining function and supporting function when the water stopping device 1 is attached to the door frame 10. That is, a water stopping device 1 with excellent watertightness maintaining function and supporting function can be provided.
In particular, by providing the vertical support mechanism 50B, the support function of the underside 14 of the inner opening 11 of the door frame 10 relative to the water-stopping device 1 can be improved, making it possible to more firmly fix the water-stopping device 1 to the inner opening 11 of the door frame 10.

EMBODIMENT 7
As shown in Figure 8, the water-stopping device 1 of embodiment 7 is configured so that the water-stopping wall 2 is divided into a left side water-stopping wall 2A and a right side water-stopping wall 2B, and is further configured so as to include a connecting means 60 for connecting the right end portion of the left side water-stopping wall 2A to the left end portion of the right side water-stopping wall 2B.

As shown in FIG. 8(a), for example, the right watertight wall 2B has a shorter width in the left and right directions than the watertight wall 2 shown in FIG. 2 of the first embodiment, and does not include the left locking portion 6 and the left watertightness maintaining means 3, but includes the right watertightness maintaining means 4 and the lower watertightness maintaining means 5b. The lower watertightness maintaining means 5b has the same configuration as the lower watertightness maintaining means 5 described above.

The left side waterstop wall 2A is a wall extending in the vertical direction and includes an opposing plate portion 71 formed of a flat plate having an opposing surface 70 facing the left end face 22A of the right side waterstop wall 2B, a left side engagement portion 6 formed of a flat plate extending to the left from the front end edge of the opposing plate portion 71, and a rear plate portion 73 formed of a flat plate extending to the right from the rear end edge of the opposing plate portion 71 and having an opposing surface 72 facing the rear wall surface 21b of the wall plate portion 2a of the right side waterstop wall 2B.
A rear watertightness maintaining means 75 formed of a flat sealant or the like is attached to almost the entire surface of the opposing surface 72, a left watertightness maintaining means 3 is provided on almost the entire surface of a left end face 70a, which is the surface opposite to the opposing surface 70 of the opposing plate portion 71, and, for example, a watertightness maintaining means 5a similar to the lower watertightness maintaining means 5 is attached to these lower end faces so as to cover the lower end faces of the opposing plate portion 71, the rear plate portion 73, the rear watertightness maintaining means 75, and the left watertightness maintaining means 3. In other words, the left end face 70a of the opposing plate portion 71 functions as the left end face 22 of the waterstop wall 2 of the first embodiment.

The connecting means 60 is a means for applying left-right force to the opposing surfaces 22A, 70 of the right end portion of the left-side waterstop wall 2A and the left end portion of the right-side waterstop wall 2B, respectively, to press the watertightness maintaining means 3 on the left side of the left-side waterstop wall 2A and the watertightness maintaining means 4 on the right side of the right-side waterstop wall 2B against the surfaces 12, 13 of the opposing inner opening 11 of the door frame 10.
The connecting means 60 is composed of, for example, a fixed wedge 61 fixed to the left end face 22A of the right-side water-stopping wall 2B, and an insertion wedge 62 inserted between the fixed wedge 61 and the opposing surface 70 of the opposing plate portion 71 of the left-side water-stopping wall 2A that faces the left end face 22A of the right-side water-stopping wall 2B, as shown in Figure 8.
To prevent the insertion wedge 62 from being lost, it is preferable to connect the insertion wedge 62 to the water blocking wall 2 with a connecting string 63.

According to the waterstop device 1 of the seventh embodiment, first, the outer surface of the watertightness maintaining means 4 on the right side of the right waterstop wall 2B is opposed to the right surface 13 of the inner opening 11 of the door frame 10, and the outer surface of the watertightness maintaining means 3 on the left side of the left waterstop wall 2A is opposed to the left surface 12 of the inner opening 11 of the door frame 10. Then, the rear wall surface 21b of the wall plate portion 2a of the right waterstop wall 2B and the rear watertightness maintaining means 75 of the left waterstop wall 2A are brought into close contact with each other, and the left waterstop wall 2A and the right waterstop wall 2B are pressed downward to bring the lower surface of the watertightness maintaining means 5a on the lower side of the left waterstop wall 2A and the lower surface of the watertightness maintaining means 5b on the lower side of the right waterstop wall 2B into close contact with the lower surface 14 of the inner opening 11 of the door frame 10, and then the fitting wedge 62 is fitted between the fixed wedge 61 fixed to the left end surface 22A of the right waterstop wall 2B and the facing surface 70 of the left waterstop wall 2A.
As a result of the above, as shown in Figure 8 (b), watertightness is maintained between the rear wall surface 21b of the wall panel portion 2a of the right-side waterstop wall 2B and the rear watertightness maintaining means 75 of the left-side waterstop wall 2A, watertightness is maintained between the right-side watertightness maintaining means 4 of the right-side waterstop wall 2B and the right surface 13 of the inner opening 11 of the door frame 10, watertightness is maintained between the left-side watertightness maintaining means 3 of the left-side waterstop wall 2A and the left surface 12 of the inner opening 11 of the door frame 10, and watertightness is maintained between the watertightness maintaining means 5a on the lower side of the left-side waterstop wall 2A and the watertightness maintaining means 5b on the lower side of the right-side waterstop wall 2B and the lower surface 14 of the inner opening 11 of the door frame 10.Furthermore, a waterstop device 1 is obtained in which the left-side waterstop wall 2A and the right-side waterstop wall 2B, which are divided into left and right parts, are supported on the surfaces 12, 13 of the inner opening 11 of the door frame 10.

EMBODIMENT 8
As shown in Figure 9, the water-stopping device 1 of embodiment 8 is configured so that the water-stopping wall 2 is divided into a left side water-stopping wall 2C and a right side water-stopping wall 2D, and is also configured so that it is provided with left and right connecting means 60A and front and rear connecting means 60B that connect the right end portion of the left side water-stopping wall 2C and the left end portion of the right side water-stopping wall 2D.

As shown in FIG. 9(a), for example, the right-side waterstop wall 2D has a shorter left-right width than the waterstop wall 2 shown in FIG. 2 of the first embodiment, and does not include a right-side engaging portion 7 and a left-side watertightness maintaining means 3, but includes a right-side watertightness maintaining means 4 and a lower-side watertightness maintaining means 5b. The lower-side watertightness maintaining means 5b has the same configuration as the lower-side watertightness maintaining means 5 described above. In other words, the right-side waterstop wall 2D does not include the right-side engaging portion 7 of the right-side waterstop wall 2B described above.

The left side waterstop wall 2C is a wall with a concave cross-section extending in the vertical direction, and includes an opposing plate portion 81 formed of a flat plate having an opposing surface 80 opposing the left end surface 22A of the right side waterstop wall 2D, a rear wall plate portion 83 formed of a flat plate extending to the right from the rear end edge of the opposing plate portion 81 and having an opposing surface 82 opposing the rear wall surface 21b of the wall plate portion 2a of the right side waterstop wall 2D, and a front wall plate portion 85 formed of a flat plate extending to the right from the front end edge of the opposing plate portion 81 and having an opposing surface 84 opposing the front end surface of the left plate portion of the right side waterstop wall 2D, the left front end surface of the lower plate portion 2d of the right side waterstop wall 2D, and the left front end surface of the upper plate portion 2e of the right side waterstop wall 2D.
In other words, the right end portion of the left water stopping wall 2C is configured to include an opposing plate portion 81 that faces the left end face 22A of the right water stopping wall 2D, and a rear wall plate portion 83 and a front wall plate portion 85 that serve as front and rear wall plates that sandwich the front-to-rear faces of the left end portion of the right water stopping wall 2D from the front and rear.
A front watertightness maintaining means 86 formed of a flat sealant or the like is attached to almost the entire surface of the opposing surface 84 of the rear plate, a left watertightness maintaining means 3 is attached to almost the entire surface of a left end face 80a, which is the surface opposite to the opposing surface 80 of the opposing plate portion 81, and a lower watertightness maintaining means 5a is attached to these lower end faces so as to cover the lower end faces of the opposing plate portion 81, the rear wall plate portion 83, the front wall plate portion 85, the front watertightness maintaining means 86, and the left watertightness maintaining means 3. In other words, the left end face 80a of the opposing plate portion 81 functions as the left end face 22 of the waterstop wall 2 of the first embodiment.

The left and right connecting means 60A are means for applying left and right forces to the right end portion of the left waterstop wall 2C and the left end portion of the right waterstop wall 2D, thereby pressing the left side watertightness maintaining means 3 of the left side waterstop wall 2C and the right side watertightness maintaining means 4 of the right side waterstop wall 2D against the surfaces 12, 13 of the inner opening 11 of the opposing door frame 10.
The left and right connecting means 60A are, for example, as shown in Figure 9, composed of a fixed wedge 61A fixed to the left end face 22A of the right-side water-stopping wall 2D and an insertion wedge 62A inserted between the fixed wedge 61A and the opposing surface 80 of the opposing plate portion 81 of the left-side water-stopping wall 2C that faces the left end face 22A of the right-side water-stopping wall 2D.

The front/rear connecting means 60B is connecting means which applies a front/rear force to one of the front and rear wall panels (e.g., rear wall panel portion 83, front wall panel portion 85) provided on one of the right end portion of the left water stop wall 2C and the left end portion of the right side water stop wall 2D, and one of the front/rear surfaces (e.g., the surface of the left side portion of the rear wall surface 21b of the right side water stop wall 2D, or the end surface of the left side portion in front of the right side water stop wall 2D) provided on the other of the right end portion of the left side water stop wall 2C and the left end portion of the right side water stop wall 2D that faces the one of the wall panels, thereby connecting the right end portion of the left side water stop wall 2C and the left end portion of the right side water stop wall 2D in the front/rear direction.
The front and rear connecting means 60B are, for example, as shown in Figure 9, composed of a fixed wedge 61B fixed to the surface of the left side portion of the rear wall surface 21b of the right-side water-stopping wall 2D, and an insertion wedge 62B inserted between the fixed wedge 61B and the opposing surface 82 of the rear wall panel portion 83 of the left-side water-stopping wall 2C that faces the surface of the left side portion of the rear wall surface 21b of the right-side water-stopping wall 2D.
In addition, it is preferable that the fitting wedges 62A, 62B are connected to the water blocking wall 2 with a connecting string 63 to prevent them from being lost.

According to the water-stopping device 1 of embodiment 8, first, the outer surface of the watertightness maintaining means 4 on the right side of the right-side water-stopping wall 2D is opposed to the right surface 13 of the inner opening 11 of the door frame 10, and the outer surface of the watertightness maintaining means 3 on the left side of the left-side water-stopping wall 2C is opposed to the left surface 12 of the inner opening 11 of the door frame 10, and the opposing surface 80 of the left-side water-stopping wall 2C is opposed to the left end surface 22A of the right-side water-stopping wall 2D, the opposing surface 82 of the left-side water-stopping wall 2C is opposed to the left end surface of the rear wall surface 21b of the right-side water-stopping wall 2D, and the opposing surface 84 of the left-side water-stopping wall 2C is opposed to the left end surface on the front side of the right-side water-stopping wall 2D.
Then, the left side waterstop wall 2C and the right side waterstop wall 2D are pressed downward to bring the underside of the watertightness maintaining means 5a on the lower side of the left side waterstop wall 2C and the underside of the watertightness maintaining means 5b on the lower side of the right side waterstop wall 2D into close contact with the underside 14 of the inner opening 11 of the door frame 10, and then an insertion wedge 62A is inserted between the fixed wedge 61A fixed to the left end face 22A of the right side waterstop wall 2D and the opposing face 80 of the left side waterstop wall 2C.
Furthermore, an insertion wedge 62B is inserted between a fixed wedge 61B fixed to the left end surface of the rear wall surface 21b of the right-side water stop wall 2D and the opposing surface 82 of the left-side water stop wall 2A.
As a result of the above, watertightness is maintained between the left front end face of the right-side waterstop wall 2D and the front watertightness maintaining means 86 of the left-side waterstop wall 2C, as well as watertightness between the right-side watertightness maintaining means 4 of the right-side waterstop wall 2D and the right surface 13 of the inner opening 11 of the door frame 10, watertightness between the left-side watertightness maintaining means 3 of the left-side waterstop wall 2C and the left surface 12 of the inner opening 11 of the door frame 10, and watertightness between the watertightness maintaining means 5a on the lower side of the left-side waterstop wall 2C and the watertightness maintaining means 5b on the lower side of the right-side waterstop wall 2D and the lower surface 14 of the inner opening 11 of the door frame 10.Furthermore, a waterstop device 1 is obtained in which the left-side waterstop wall 2C and right-side waterstop wall 2D divided into left and right parts are supported on the surfaces 12, 13 of the inner opening 11 of the door frame 10.

In other words, the water-stopping device 1 of embodiments 7 and 8 is configured to have a left side water-stopping wall 2A and a right side water-stopping wall 2B that are divided into left and right parts, so that each water-stopping wall can be made compact and a water-stopping device 1 can be provided that is applicable to openings with relatively large opening widths on the left and right sides.
Furthermore, the operation of attaching and detaching the water stop device 1 to and from the inner opening 11 of the door frame 10 is facilitated, and the watertightness maintaining function and support function are further improved when the water stop device 1 is attached to the door frame 10. In other words, a water stop device 1 with excellent watertightness maintaining function and support function can be provided.

Furthermore, in the water stopping device 1 according to the seventh and eighth embodiments, the coupling means is composed of a fixed wedge and an insertion wedge, so that the water stopping device 1 can be attached in a fixed state to the inner opening 11 of the door frame 10 by the simple operation of inserting the insertion wedge, and the water stopping device 1 can be attached in a fixed state to the inner opening 11 of the door frame 10 by the simple operation of inserting the insertion wedge, and the watertightness maintaining function and support function are improved when the water stopping device 1 is attached to the inner opening 11 of the door frame 10. Also, the water stopping device 1 can be easily removed from the inner opening 11 of the door frame 10 by simply removing the insertion wedge.
In other words, when the connecting means is composed of a fixed wedge and an inserting wedge, the attachment and detachment operation to and from the inner opening 11 of the door frame 10 becomes easier, and the watertightness maintaining function and support function are improved when the water-stopping device is attached to the inner opening 11 of the door frame 10.

In addition, in the seventh and eighth embodiments, the configuration of the left water stop wall may be applied to the right water stop wall, and the configuration of the right water stop wall may be applied to the left water stop wall.

In the eighth embodiment, one of the right end portion of the left water stop wall and the left end portion of the right water stop wall may be configured with front and rear wall panels that sandwich the front and rear faces of the other of the right end portion of the left water stop wall and the left end portion of the right water stop wall from the front and rear.

In addition, in the seventh embodiment (FIG. 8), the waterproof device 1 may be configured without the engagement portions.
In addition, in the eighth embodiment (FIG. 9), the waterproof device 1 may be configured to include each of the locking portions.
In embodiments 7 and 8, the water-stopping device 1 is configured without any locking portions, so that, as described above, the water-stopping device 1 can be applied to openings such as an opening between the left and right guide rails of a shutter device, and an opening that constitutes an entrance/exit for a gate, a fence, etc.

EMBODIMENT 9
As shown in Fig. 10, the waterproofing device 1 according to the ninth embodiment is configured to include watertightness maintaining means 3, 4, and 5 each including a leaf spring 100 and a seal material 110. Note that Fig. 10 illustrates the watertightness maintaining means 3 as an example.

The leaf spring 100 is made of a long material having, for example, a V-shaped or U-shaped cross section, and is configured with an attachment portion 101 attached to the left end face 22, the right end face 23, and the bottom end face 24 of the waterstop wall 2, which are the attachment surfaces of the waterstop wall 2, and a resilient portion 102 provided to extend from the attachment portion 101, with the plate portion on one side of the V-shape or U-shape functioning as the attachment portion 101 and the plate portion on the other side of the V-shape or U-shape functioning as the resilient portion 102. Then, the left end face 22, the right end face 23, and the bottom end face 24, which are the attachment surfaces of the waterstop wall 2, and the outer surface 104 of the attachment portion 101 are bonded with an adhesive or the like so that the boundary between the attachment portion 101 and the resilient portion 102, i.e., the bent portion 103, is positioned on the tip side when the waterstop wall 2 is inserted into the inner opening 11 of the door frame 10.
The sealing material 110 is formed, for example, in a plate shape, and the plate surface of the plate-shaped sealing material 110 and substantially the entire outer surface 105 of the resilient portion 102 are bonded with an adhesive or the like.
Furthermore, the leaf spring 100 is formed, for example, from metal, synthetic resin, etc., and is configured so that when force is applied to the plate portion on one side of the V or U shape and the plate portion on the other side, the elasticity of the bent portion, which is the boundary between the plate portion on one side of the V or U shape and the plate portion on the other side, urges the plate portion on one side of the V or U shape and the plate portion on the other side in a direction away from each other.
The seal material 110 may be the same as the watertightness maintaining means 3, 4, and 5 described in the first embodiment.

The watertightness treatment by the watertightness maintaining means 3 in the waterstop device 1 according to the ninth embodiment will be described with reference to FIG.
First, as shown in Fig. 10(a), when inserting the water stop device 1 into the inner opening 11 of the door frame 10 from the front side (outdoor side), the bent portion 103 of the leaf spring 100 constituting the watertightness maintaining means 3 is positioned at the tip side in the insertion direction, and then the water stop device 1 is inserted into the inner opening 11 of the door frame 10 from the front side (outdoor side). During this insertion, when the seal material 110 constituting the watertightness maintaining means 3 comes into contact with and is pressed against the left surface 12 of the inner opening 11, the elastic portion 102 of the leaf spring 100 receives a force from the left surface 12 of the inner opening 11 and deforms in a direction approaching the mounting portion 101 with the bent portion 103 as the center of rotation. Then, as shown in Fig. 10(b), the elastic force after the elastic portion 102 is deformed presses the seal material 110 against the left surface 12 of the inner opening 11, so that watertightness between the left surface 12 of the inner opening 11 and the seal material 110 is maintained.
It goes without saying that the watertightness maintaining means 4, 5 are constructed in the same manner as the watertightness maintaining means 3 described above, and provide the same operational effects.

According to the water stop device 1 of the ninth embodiment, the water stop device 1 can be obtained with a simple installation operation of inserting the water stop device 1 into the inner opening 11 of the door frame 10 from the front side (outdoor side), resulting in a water stop device 1 with excellent watertightness maintaining function and support function.

EMBODIMENT 10
The waterproofing device 1 according to the tenth embodiment is configured to include watertightness maintaining means 3, 4, and 5 using a seal material 120 and a seal material 130 having water swelling properties, as shown in Fig. 11. Note that Fig. 11 illustrates the watertightness maintaining means 3.

As shown in Figure 11 (a), the sealing material 120 is attached to the left end face 22, right end face 23, and bottom end face 24, which are the mounting surfaces of the water-stopping wall 2, so that when the water-stopping device 1 is inserted into the inner opening 11 of the door frame 10 from the front side (outdoor side), a gap R is created between the left surface 12 of the inner opening 11 and the sealing material 120.
Then, from the rear side (indoor side), as shown in Figure 11 (b), a sealant 130 having water swelling properties is filled into the gap R between the mounting surface of the water-stopping wall 2 inserted into the inner opening 11 of the door frame 10 and the surface of the inner opening 11 of the door frame 10, thereby maintaining watertightness between the sealant 120 and the surface of the inner opening 11 of the door frame 10.
As the water-swellable seal material 130, for example, a long piece of anticorrosive water-swellable rubber having a circular cross section may be used.
The seal material 120 may be the same as the watertightness maintaining means 3, 4, and 5 described in the first embodiment.

The watertightness treatment by the watertightness maintaining means 3 in the waterstop device 1 according to the tenth embodiment will be described with reference to FIG.
11(a), the water stop device 1 is inserted from the front side (outdoor side) into the inner opening 11 of the door frame 10. At this time, a gap R is generated between the sealant 120 attached to the left end surface 22 of the water stop wall 2 and the left surface 12 of the inner opening 11.
Then, a sealant 130 having water swelling properties is filled into the gap R from the rear side (indoor side) as shown in Figure 11 (b), thereby maintaining watertightness between the sealant 120 and the left surface 12 of the inner opening 11 of the door frame 10.
It goes without saying that the watertightness maintaining means 4, 5 are constructed in the same manner as the watertightness maintaining means 3 described above, and provide the same operational effects.

According to the water stop device 1 of the tenth embodiment, the water stop device 1 is inserted into the inner opening 11 of the door frame 10 from the front side (outdoor side), and then the gap R between the seal material 120 attached to the mounting surface of the water stop wall 2 and the surface of the inner opening 11 of the door frame 10 is filled with the seal material 130 having water swelling properties from the rear side (indoor side), resulting in a water stop device 1 with excellent watertightness maintaining and supporting functions.

EMBODIMENT 11
As shown in Fig. 12, the water-stopping device 1 according to the eleventh embodiment is configured to include water-tightness maintaining means 3, 4, and 5 using a sealant 120 and a sealant 130 having water-swelling properties, and is configured such that the arrangement of the sealant 120 and the sealant 130 having water-swelling properties is different from that of the tenth embodiment. Note that Fig. 12 illustrates the water-tightness maintaining means 3.

12(a), the sealant 120 is attached to the mounting surface of the water stopping wall 2 so that, when the water stopping device 1 is inserted into the inner opening 11 of the door frame 10 from the front side (outdoor side), no gaps are generated on the front side between the surfaces of the inner opening 11 (left surface 12, right surface 13, bottom surface 14) and the mounting surfaces of the water stopping wall 2, that is, the left end surface 22, right end surface 23, and bottom end surface 24. However, gaps are generated on the rear side between the surfaces of the inner opening 11 and the mounting surfaces of the water stopping wall 2.
After the water-stopping device 1 is inserted into the inner opening 11 of the door frame 10 from the front side (outdoor side), as shown in Figure 12 (b), a sealant 130 having water-swelling properties is filled from the rear side (indoor side) into the gap between the surface of the inner opening 11 formed behind the sealant 120 and the mounting surface of the water-stopping wall 2, thereby maintaining watertightness between the mounting surface of the water-stopping wall 2 and the surface of the inner opening 11 of the door frame 10.
That is, in the water stop device 1 according to the eleventh embodiment, the sealant 120 is attached to the attachment surface of the water stop wall 2 so that, when the water stop wall 2 is inserted into the inner opening 11 of the door frame 10 from the front side (outdoor side), the sealant 120 is positioned between the attachment surface of the water stop wall 2 and the surface of the inner opening 11, biased toward the front side, which is opposite to the direction of insertion of the water stop device 1. The gap between the attachment surface of the water stop wall 2 inserted into the inner opening 11 of the door frame 10 and the surface of the inner opening 11 is filled from the rear side (indoor side) with the sealant 130 having water swelling properties, thereby maintaining watertightness between the attachment surface of the water stop wall 2 and the surface of the inner opening 11.

The watertightness treatment by the watertightness maintaining means 3 in the waterstop device 1 according to the eleventh embodiment will be described with reference to FIG.
12(a), the water stop device 1 is inserted from the front side (outdoor side) into the inner opening 11 of the door frame 10. At this time, a sealant 120 is placed on the front side between the left surface 12 of the inner opening 11 and the left end surface 22 of the water stop wall 2 so as to maintain watertightness between the left surface 12 of the inner opening 11 and the left end surface 22 of the water stop wall 2.
Then, from the rear side (indoor side), the gap between the left surface 12 of the inner opening 11 formed behind the sealing material 120 and the left end surface 22 of the water-stopping wall 2 is filled with sealing material 130 having water-swelling properties, as shown in Figure 12 (b).As a result, the watertightness performance of the sealing material 120 and the sealing material 130 having water-swelling properties is exerted in front of and behind the gap between the left surface 12 of the inner opening 11 and the left end surface 22 of the water-stopping wall 2, and good watertightness is maintained between the left surface 12 of the inner opening 11 and the left end surface 22 of the water-stopping wall 2.
It goes without saying that the watertightness maintaining means 4 and 5 are constructed in the same manner as the watertightness maintaining means 3 described above, and provide the same operational effects.

According to the water stop device 1 of the eleventh embodiment, the water stop device 1 is inserted from the front side (outdoor side) into the inner opening 11 of the door frame 10, and a sealant 120 is placed on the front side between the surface of the inner opening 11 and the surface of the water stop wall 2 to maintain watertightness between the surface of the inner opening 11 and the surface of the water stop wall 2. Then, a sealant 130 having water swelling properties is filled from the rear side (indoor side) into the gap formed behind the sealant 120 between the surface of the inner opening 11 and the surface of the water stop wall 2. This simple installation procedure provides a water stop device 1 with excellent watertightness maintaining and supporting functions.

EMBODIMENT 12
In the water-stopping device 1 according to the above-mentioned embodiment 3, as shown in FIG. 4, the sealing material constituting the watertightness maintaining means 3, 4, 5 is formed so that the thickness dimension from the mounting surface of the water-stopping wall 2 to which the sealing material is attached gradually increases from the tip side to the end side when the water-stopping wall 2 is inserted into the inner opening 11 from the front side (outdoor side), and an example is shown in which the surfaces of the sealing material that come into contact with the left surface 12, right surface 13, and bottom surface 14 of the inner opening 11 of the door frame 10 are formed into inclined surfaces.
In contrast, in the water-stopping device 1 of embodiment 12, as shown in Figure 13, the left end face 22, right end face 23, and bottom end face 24 of the water-stopping wall 2 are formed as inclined surfaces that gradually approach the left face 12, right face 13, and bottom face 14 of the inner opening 11 of the door frame 10 from the tip side to the end side when the water-stopping wall 2 is inserted into the inner opening 11 from the front side (outdoor side).
Furthermore, after the water stopping wall 2 is inserted into the inner opening 11 from the front side (outdoor side), the gaps between the inclined surfaces of the water stopping wall 2 and the left face 12, right face 13, and bottom face 14 of the inner opening 11 of the door frame 10 are filled from the rear side (indoor side) with a sealant 130 having water swelling properties or a sealant 120, thereby maintaining watertightness between the inclined surfaces (left end face 22, right end face 23, bottom face 24) of the water stopping wall 2 and the faces (left face 12, right face 13, bottom face 14) of the inner opening 11 of the door frame 10. Note that a watertightness maintaining means 3 is illustrated in FIG. 13.

Based on FIG. 13, the watertight treatment by the watertightness maintaining means 3 in the waterstop device 1 according to the twelfth embodiment will be described.
First, as shown in Fig. 13(a), the water stop device 1 is inserted into the inner opening 11 of the door frame 10 from the front side (outdoor side). At this time, a gap with a triangular or trapezoidal cross section is formed between the left surface 12 of the inner opening 11 and the left end surface 22 formed on the inclined surface of the water stop wall 2. The cross-sectional width of this gap becomes narrower as it approaches the front side.
13(b), a sealant 130 having water swelling properties or a sealant 120 is filled from the rear side (indoor side) into the gap between the left surface 12 of the inner opening 11 and the left end surface 22 formed on the inclined surface of the waterstop wall 2, thereby maintaining good watertightness between the left surface 12 of the inner opening 11 and the left end surface 22, which is the inclined surface of the waterstop wall 2. In this case, the sealant 130 or the like filled into the gap from the rear side (indoor side) is crushed against the surface that forms the narrow portion on the front side of the gap and is firmly filled into the narrow space, thereby further improving the watertightness between the left surface 12 of the inner opening 11 and the left end surface 22 of the waterstop wall 2.
It goes without saying that the watertightness maintaining means 4, 5 are constructed in the same manner as the watertightness maintaining means 3 described above, and provide the same operational effects.

According to the water stop device 1 of the twelfth embodiment, the water stop device 1 is inserted from the front side (outdoor side) into the inner opening 11 of the door frame 10, and then a water-swelling sealant 130 or the like is filled from the rear side (indoor side) into the small gap at the front end formed between the surface of the inner opening 11 and the inclined surface of the water stop wall 2. This simple installation procedure provides a water stop device 1 with excellent watertightness maintenance and support functions.

EMBODIMENT 13
The water-stopping device 1 of embodiment 13 is configured, instead of the watertightness maintaining means 3, 4, 5 which are a combination of the leaf spring 100 and sealing material 110 described in embodiment 9 (Figure 10), to include a long elastic sealing material having, for example, a V-shaped or U-shaped cross-section, and which has mounting portions attached to the left end face 22 of the water-stopping wall 2, the right end face 23 of the water-stopping wall 2, and the lower end face 24 of the water-stopping wall 2, which are the mounting surfaces of the water-stopping wall 2, and a resilient portion extending from the mounting portions.
Furthermore, the elastic sealing material is configured so that when force is applied to the plate portion on one side of the V or U shape and the plate portion on the other side, the elasticity of the bent portion, which is the boundary between the plate portion on one side of the V or U shape and the plate portion on the other side, urges the plate portion on one side of the V or U shape and the plate portion on the other side in a direction separating them.
In addition, similar to the leaf spring 100 described in embodiment 9 (Figure 10), the elastic sealing material is configured such that the outer surface of the mounting portion of the elastic sealing material and the left end face 22, right end face 23 and bottom end face 24, which are the mounting surfaces of the water-stopping wall 2, are bonded with an adhesive or the like so that the bent portion, which is the boundary between the mounting portion and the resilient portion, is positioned at the tip side when the water-stopping wall 2 is inserted into the inner opening 11 of the door frame 10.
The elastic sealing material may be, for example, a single-material elastic sealing material made of only rubber or other sealing material, or a composite elastic sealing material made of a core material made of a material other than the sealing material and a sealing material provided to cover the periphery of the core material. The composite elastic sealing material may be manufactured by, for example, two-color molding or other manufacturing methods. For example, the composite elastic sealing material may be an elastic sealing material having a core material made of a leaf spring made of metal, synthetic resin, or the like, and the periphery of the leaf spring covered with a sealing material.

According to the water stop device 1 of the thirteenth embodiment, as in the ninth embodiment (Fig. 10), the water stop device 1 can be obtained with excellent watertightness maintaining and support functions by a simple installation operation of inserting the water stop device 1 into the inner opening 11 of the door frame 10 from the front side (outdoor side).

EMBODIMENT 14
As shown in Figure 14, the water-stopping device 1 of embodiment 14 is configured, as explained in embodiment 3 (Figures 4(a) and (b)), to have protrusions on inclined surfaces formed as surfaces that come into contact with the left surface 12, right surface 13, and bottom surface 14 of the inner opening 11 of the door frame 10 so that the thickness dimension of the sealing material constituting the watertightness maintaining means 3, 4, 5 gradually increases from the tip side to the end side when the water-stopping wall 2 is inserted into the inner opening (opening) 11 from the front side (outdoor side) from the left end surface 22, right end surface 23, and bottom end surface 24, which are the mounting surfaces to which the sealing material constituting the watertightness maintaining means 3, 4, 5 is attached.

Figure 14 (a) shows a watertightness maintaining means 5 having multiple protrusions 5d on an inclined surface 5a formed as a surface that contacts the underside 14 of the inner opening 11 of the door frame 10 so that the thickness dimension from the lower end surface 24 of the waterstop wall 2, which is the mounting surface, gradually increases from the tip side toward the end side as described above.
Figure 14 (b) shows the left-side watertightness maintaining means 3 having multiple protrusions 3d on an inclined surface 3a formed as a surface that contacts the left surface 12 of the inner opening 11 of the door frame 10 so that the thickness dimension from the left end surface 22 of the waterstop wall 2, which is the mounting surface, gradually becomes thicker from the tip side toward the end side as described above.
Similarly, although not shown, the right-side watertightness maintaining means 4 has multiple protrusions formed on the inclined surface that contacts the right surface 13 of the inner opening 11 of the door frame 10 so that the thickness dimension from the right end surface 23 of the water-stopping wall 2, which is the mounting surface, gradually increases from the tip side toward the end side as described above.

As shown in Figs. 14(a) and (b), the protrusions 3d, 5d are provided at intervals along the front-rear direction (end-end direction) on each inclined surface 3a, 5a, and are formed to extend in the normal direction of each inclined surface 3a, 5a. The protrusions 3d, 5d provided on each inclined surface 3a, 5a are formed, for example, in a straight line with the same protrusion amount in a cross-sectional view. Note that the shape and protrusion amount of the protrusion in a cross-sectional view may be, for example, a sickle-shaped cross section protruding diagonally rearward (end side) from the inclined surface as shown in Figs. 4(c) and (d) of embodiment 3, and the protrusion amount and size of the protrusion provided on the rear side (end side) may be larger, and the shape and protrusion amount may be changed as appropriate.

According to the water-stopping device 1 of embodiment 14, even if the designed parallelism of the left end face 22, right end face 23, and bottom end face 24 of the water-stopping wall 2 facing the left face 12, right face 13, and bottom face 14 of the door frame 10 is not maintained when the water-stopping device 1 is inserted from the front side (outdoor side) into the inner opening 11 of the door frame 10, the protrusions provided on the watertightness maintaining means 3, 4, and 5 can absorb dimensional changes in the gap between the left face 12 and the left end face 22, the gap between the right face 13 and the right end face 23, and the gap between the bottom face 14 and the bottom end face 24. This makes it easy to insert the water-stopping device 1 into the inner opening 11 of the door frame 10 from the front side (outdoor side), while providing a water-stopping device 1 with excellent watertightness maintaining function and support function. When the designed parallelism is not maintained, it means that when the door frame 10 and water stop wall 2 manufactured within the processing tolerance range are combined, for example, narrow and wide gaps will appear in the extension direction of the gap between the left face 12 and the left end face 22.

In the embodiment 14, the protrusions are formed in the embodiment 3 (Figs. 4(a) and (b)). However, in each of the above-mentioned embodiments except for the embodiment 3 (Figs. 4(c) and (d)), the same effect as the embodiment 14 can be obtained by providing the protrusions on the surfaces of the watertightness maintaining means 3, 4, and 5 that face and contact the left surface 12, right surface 13, and bottom surface 14 of the door frame 10.

EMBODIMENT 15
In the water-stopping device 1 of embodiments 1 to 3, etc., a configuration has been exemplified in which the sealing material constituting the watertightness maintaining means 3, 4, 5 is attached to the left end face 22, right end face 23 and bottom end face 24 of the water-stopping wall 2. However, in the water-stopping device 1 of embodiment 15, as shown in Figure 15, the watertightness maintaining means 3, 4, 5 are configured so that the sealing material is formed so as to wrap around the indoor side wall surface 21b of the wall panel portion 2a in addition to the left end face 22, right end face 23 and bottom end face 24 of the water-stopping wall 2, which are the mounting surfaces.
As shown in Fig. 15, when the sealing material according to embodiment 15 is explained using embodiment 3 (Figs. 4(a) and (b)), the portions attached to the left end face 22, right end face 23 and bottom end face 24 of the water stopping wall 2 are formed so that the thickness dimension from the attached surface of the water stopping wall 2 gradually increases from the tip side to the end side when the water stopping wall 2 is inserted into the inner opening (opening) 11 from the front side (outdoor side), and is formed to have a flat extension piece that continues to this tip side and extends along the indoor wall surface 21b of the wall panel portion 2a. In other words, the sealing material is configured in a roughly L-shape when viewed in cross section as shown in Fig. 14.

Figure 15 (a) shows a watertightness maintaining means 5 formed so that an extension piece 5Z extending from the lower end surface 24 of the water-stopping wall 2, which is the mounting surface, along the indoor side wall surface 21b from the tip side to the end side as described above is attached to the wall surface 21b.
Figure 15 (b) shows the left-side watertightness maintaining means 3, which is formed so that an extension piece 3Z extending from the left end face 22 of the water-stopping wall 2, which is the mounting surface, along the indoor side wall face 21b from the tip side to the end side as described above, is attached to the wall face 21b.
Similarly, although not shown, the right-side watertightness maintaining means 4 is formed so that an extension piece extending from the right end face 23 of the water-stopping wall 2, which is the mounting surface, along the indoor side wall face 21b from the tip side to the end side as described above is attached to the wall face 21b.

According to the water stop device 1 of the fifteenth embodiment, by attaching the extension piece to the wall surface 21b, when the water stop device 1 is inserted into the inner opening 11 of the door frame 10 from the front side (outdoor side), the watertightness maintaining means 3, 4, 5 can be prevented from peeling off due to friction with the left surface 12, right surface 13, and bottom surface 14 of the door frame 10. That is, as described in the first to third embodiments, if the watertightness maintaining means 3, 4, 5 are attached only to the left end surface 22, right end surface 23, and bottom end surface 24 of the water stop wall 2, the force due to friction with the door frame 10 acts parallel to the left end surface 22, right end surface 23, and bottom end surface 24, and acts to peel off the watertightness maintaining means 3, 4, 5 from the left end surface 22, right end surface 23, and bottom end surface 24. However, by attaching the extension piece to the wall surface 21b, this peeling force can be resisted, and stable watertightness can be obtained even when the water stop device 1 is used repeatedly.

The technical ideas of the waterproofing device 1 of the present invention according to the first to fifteenth embodiments are as follows.
The technical idea of the first and second embodiments (Figures 1 to 3) is to provide a watertightness maintaining means on the surfaces of the waterstop wall (left end surface, right end surface, bottom end surface) to maintain watertightness between the waterstop wall surface and the opening surface (left surface, right surface, bottom surface) and to maintain the support function of the opening that supports the waterstop wall.
In embodiment 3 (Figure 4), the shape of the watertightness maintaining means is designed to gradually thicken from the tip to the end when the waterstop wall is inserted into the opening, thereby maintaining the watertightness between the surface of the waterstop wall and the surface of the opening and the support function of the opening that supports the waterstop wall, while also making it easier to attach and detach the waterstop wall to and from the opening.
In embodiment 4 (Figure 5), a watertightness maintaining means having a groove is used, and after a waterstop wall is inserted into an opening, a pressing means is fitted into the groove of the watertightness maintaining means to press the watertightness maintaining means against the surface of the opening. This technical idea maintains the watertightness between the surface of the waterstop wall and the surface of the opening and the support function of the opening that supports the waterstop wall, while also making it easy to attach and detach the waterstop wall to and from the opening.
The fifth embodiment (FIG. 6) has a technical idea of improving the support function of the opening portion that supports the water blocking wall by providing a support mechanism on the water blocking wall.
In embodiment 6 (Figure 7), the waterstop wall is provided with a horizontal and vertical support mechanism, thereby improving the support function of the opening that supports the waterstop wall, and a watertightness maintaining means having a groove is used as one of the left and right watertightness maintaining means that is not pressed against the surface of the opening, and after the waterstop wall is installed at the opening, a pressing means is inserted into the groove of the watertightness maintaining means to press the watertightness maintaining means against the surface of the opening, thereby improving the support function of the opening that supports the waterstop wall and maintaining watertightness between the surface of the waterstop wall and the surface of the opening.
In the seventh embodiment (Figure 8) and the eighth embodiment (Figure 9), the water stopping wall is divided into a left water stopping wall and a right water stopping wall, and the technical idea is to make each water stopping wall compact and to provide a water stopping device that can be easily applied to openings with relatively large opening widths on both the left and right sides.
In embodiment 9 (Figure 10), the watertightness maintaining means is configured as a combination of a leaf spring and a sealing material, which simplifies the installation operation to the opening in the waterstop wall and utilizes the elastic force of the leaf spring to maintain watertightness between the surface of the waterstop wall and the surface of the opening.
In embodiment 10 (Figure 11) and embodiment 11 (Figure 12), the watertightness maintaining means is constructed using a sealing material and a sealing material having water-swelling properties, and the sealing material is attached to the surfaces of the water-stopping wall (left end surface, right end surface, bottom end surface). After the water-stopping wall is inserted into the opening, the sealing material having water-swelling properties is filled between the sealing material and the surface of the opening (left surface, right surface, bottom surface) or between the surface of the water-stopping wall and the surface of the opening, thereby maintaining watertightness between the surface of the water-stopping wall and the surface of the opening.
Embodiment 12 (Figure 13) is a technical idea in which, when a water-stopping wall is inserted into an opening, the faces of the water-stopping wall (left end face, right end face, bottom end face) are formed into inclined faces that gradually approach the face of the opening from the tip side to the end side when the water-stopping wall is inserted into the opening, and after the water-stopping wall is inserted into the opening, a sealant is filled between the inclined faces of the water-stopping wall and the face of the opening, thereby maintaining watertightness between the inclined faces of the water-stopping wall and the face of the opening.
In embodiment 13, a long elastic sealing material having, for example, a V-shaped or U-shaped cross-section is used as a watertightness maintaining means, and the elastic sealing material is attached to the surface of the waterstop wall (left end surface, right end surface, bottom end surface) so that the bent portion, which is the boundary between the mounting portion and the elastic portion of the elastic sealing material, is positioned at the tip side when the waterstop wall is inserted into the opening. This technical idea simplifies the mounting operation of the waterstop wall to the opening, and utilizes the elastic force of the elastic sealing material to maintain watertightness between the surface of the waterstop wall and the surface of the opening.
In addition, in embodiment 13, a configuration using a single-material elastic sealing material formed, for example, only from rubber or other sealing material also corresponds to a configuration in which the shape of the watertightness maintaining means becomes gradually thicker from the tip to the end when the waterstop wall is inserted into the opening, as in embodiment 3 (Figure 4), and therefore a configuration using the single-material elastic sealing material also incorporates the technical idea of embodiment 3.
In embodiment 14 (Figure 14), the watertightness maintaining means is equipped with a protrusion, which can absorb dimensional changes in the gap between the left face and the left end face, the gap between the right face and the right end face, and the gap between the bottom face and the bottom end face, making it easier to insert the water-stopping device 1 into the inner opening of the door frame from the front side (outdoor side), and facilitating the attachment and detachment of the water-stopping wall to the opening.
In the fifteenth embodiment (Figure 15), the watertightness maintaining means is provided with an extension piece, and the extension piece is attached to the wall surface of the water-stopping wall, thereby preventing the watertightness maintaining means from coming off due to friction with the left, right and bottom surfaces of the door frame when the water-stopping device is inserted into the door frame.

Furthermore, the water stop device 1 of the present invention may be configured by appropriately combining two or more of the configurations of the embodiments 1 to 15. For example, if the water stop device 1 is configured by combining the configuration of the watertightness maintaining means 3, 4, and 5 shown in the embodiment 4 (FIG. 5) with the configuration of the support mechanism 40 shown in the embodiment 5 (FIG. 6), it is possible to obtain a water stop device 1 with even better watertightness maintaining function and support function.
In addition, the configurations of the first to thirteenth embodiments may be appropriately replaced. For example, the configurations of the watertightness maintaining means 3, 4, and 5 shown in the fourth embodiment (FIG. 5) may be changed to the configuration of the watertightness maintaining means shown in the sixth embodiment (FIG. 7(b)).

In addition, in embodiments 1 to 6 and embodiments 9 to 13, a water-stopping wall 2 formed in a box shape with a front open and a rear closed, and equipped with a wall panel portion 2a, a left panel portion 2b, a right panel portion 2c, a lower panel portion 2d, an upper panel portion 2e, a left engagement portion 6, a right engagement portion 7, and a lower engagement portion 8, is exemplified, but the water-stopping wall may be a flat water-stopping wall that does not have the left engagement portion 6, the right engagement portion 7, and the lower engagement portion 8.
In other words, the water-stopping device of the present invention may be a water-stopping device constructed, for example, by providing watertightness maintaining members on the left end face, right end face and bottom end face of a flat water-stopping wall, and this water-stopping device can also block an opening having a left side, a right side and a bottom face, such as an opening between the left and right guide rails of a shutter device, or an opening constituting an entrance/exit for a gate, a fence, etc., to prevent water from passing through the opening.
In other words, even with this water-stopping device, by installing the water-stopping device at the opening so that the left-side watertightness maintaining means provided on the left end face of the water-stopping wall maintains watertightness between the left side of the opening, the right-side watertightness maintaining means provided on the right end face of the water-stopping wall maintains watertightness between the right side of the opening, and the lower watertightness maintaining means provided on the lower end face of the water-stopping wall maintains watertightness between the lower side of the opening, the opening can be blocked and water can be prevented from passing through the opening.

In addition, in each embodiment, an example is shown in which a watertightness maintaining means is provided on the surface of the waterstopping wall (left end surface, right end surface, bottom end surface) in order to maintain watertightness between the surface of the waterstopping wall (left end surface, right end surface, bottom end surface) and the surface of an opening such as the inner opening of a door frame (left surface, right surface, bottom surface). However, the watertightness maintaining means of each embodiment may be configured to be provided on the surface of the opening (left surface, right surface, bottom surface), or the watertightness maintaining means may be configured to be provided on both the surface of the waterstopping wall (left end surface, right end surface, bottom end surface) and the surface of the opening (left surface, right surface, bottom surface).
In other words, the water-stopping device of the present invention may at least comprise a water-stopping wall, a left-side watertightness maintaining means provided on at least one of the left end face of the water-stopping wall and the left face of the opening to maintain watertightness between the left end face of the water-stopping wall and the left face of the opening, a right-side watertightness maintaining means provided on at least one of the right end face of the water-stopping wall and the right face of the opening to maintain watertightness between the right end face of the water-stopping wall and the right face of the opening, and a lower watertightness maintaining means provided on at least one of the lower end face of the water-stopping wall and the lower face of the opening to maintain watertightness between the lower end face of the water-stopping wall and the lower face of the opening.

In addition, in the explanation of the first embodiment, it was explained that the watertightness maintaining means 3, 4, and 5 are configured as separate bodies, and that the lower end face of the left watertightness maintaining means 3 and the lower end face of the right watertightness maintaining means 4 are configured to contact the underside 14 of the inner opening 11 of the door frame 10 to maintain the watertightness performance between said underside 14, and that the left end face of the lower watertightness maintaining means 5 and the left watertightness maintaining means 3 are arranged to be in close contact with each other, and that the right end face of the lower watertightness maintaining means 5 and the right watertightness maintaining means 4 are arranged to be in close contact with each other. The watertightness maintaining means 5 may be configured to contact the underside of the inner opening 11 of the door frame 10 to maintain watertightness between the underside 14, and the left end face of the lower watertightness maintaining means 5 and the left watertightness maintaining means 3 may be configured to contact the left side 12 of the inner opening 11 of the door frame 10 to maintain watertightness between the left side, and the right end face of the lower watertightness maintaining means 5 and the right watertightness maintaining means 4 may be configured to contact the right side 13 of the inner opening 11 of the door frame 10 to maintain watertightness between the right side and 13.

In addition, as shown in the first and third embodiments, when the watertightness maintaining means 3, 4, and 5 are configured as separate bodies, the watertightness maintaining means 3, 4, and 5 are not limited to using sealing materials made of the same material. For example, as shown in FIG. 1, when inserting the watertightness maintaining device 1 in which the watertightness maintaining wall 2 and the watertightness maintaining means 3, 4, and 5 are integrated into the inner opening 11 of the door frame 10, the watertightness maintaining means 1 is inserted into the inner opening 11 of the door frame 10 while the left and right watertightness maintaining means 3 and 4 are slid into the inner opening 11 of the door frame 10 while pressing the watertightness maintaining means 5 against the lower surface 14. At this time, the friction between the watertightness maintaining means 3 and the left surface 12 and between the watertightness maintaining means 4 and the right surface 13 is greater than the friction between the watertightness maintaining means 5 and the lower surface 14. In addition, the watertightness maintaining means 3, 4, and 5 configured as separate bodies or as a single body may be provided on the door frame 10 side, or may be provided on both the door frame 10 side and the watertightness maintaining wall 2 side.

In such a case, it is advisable to use watertightness maintaining means 3, 4, 5, with the watertightness maintaining means 3 and 4 made of non-foam rubber, and the watertightness maintaining means 5 made of foam rubber. For example, if the watertightness maintaining means 3, 4, 5 are made of foam rubber, friction on the left surface 12 and right surface 13 will be high, making them difficult to push in, and there is a risk that the watertightness maintaining means 3, 4 will be damaged if an attempt is made to push them in forcibly. Therefore, by using non-foam rubber for the left and right watertightness maintaining means 3, 4, it is possible to prevent damage while still making them easier to fit in.

In addition, by using a foam rubber for the watertightness maintaining means 5, it follows the rising of the waterstop wall 2 that tends to occur when it is pushed in, maintains the watertight state between the watertightness maintaining means 5 and the underside 14, and makes it easier to achieve watertightness when attaching and detaching the waterstop device 1.

Hereinafter, the waterproofing device 1 according to the sixteenth to twenty-fourth embodiments will be described with reference to Figs. 16 to 30 .
16, 17, 25 and 28, in order to clearly show the shape of the water blocking wall 2 constituting the water blocking device 1, only the water blocking wall 2 is shown.
That is, similar to the water-stopping wall 2 described in embodiment 1 etc., the water-stopping device 1 in embodiments 16 to 24 is configured to include the water-stopping wall 2 and watertightness maintaining means 3, 4, and 5, as shown in Figures 23, 24, 26, and 29.
16 to 30, the same or corresponding parts as those shown in FIGS. 1 to 15 of the above-described first to fifteenth embodiments are designated by the same reference numerals, and description thereof will be omitted.
Moreover, hatching is omitted in the cross-sectional views of FIGS.

EMBODIMENT 16
In the water blocking walls 2 described in each of the above-mentioned embodiments 1 to 15, the wall panel portion 2a is formed of a rectangular flat plate, but the wall panel portion 2a may be formed of a hollow wall panel portion 2a formed by combining a plurality of shaped members 2m, 2m... such as aluminum extrusions, as shown in Fig. 16(c) for example. For example, the water blocking wall is provided with a wall panel portion 2a formed by combining a plurality of shaped members 2m, 2m... vertically.
That is, as shown in Figures 16, 17, 18, 23 and 24, the water-stopping device 1 is configured so as to include a wall panel portion 2a of a hollow structure (plate-shaped hollow box body) formed by combining multiple shaped members 2m, 2m... one above the other, a left-side locking portion 6 extending from the left end of a wall surface 21a located on the door 9 side of the wall panel portion 2a and engaging with the left-side door stop surface 16 of the inner opening 11 of the door frame 10, a right-side locking portion 7 extending from the right end of the wall surface 21a and engaging with the right-side door stop surface 17 of the inner opening 11 of the door frame 10, and a lower locking portion 8 extending from the lower end of the wall surface 21a and engaging with the lower door stop surface 18 of the inner opening 11 of the door frame 10.
In addition, in the water-stopping wall 2 of embodiment 16, the upper plate 2t of the wall panel portion 2a (the upper plate of the shaped member 2m that constitutes the uppermost part of the wall panel portion 2a) functions as the upper end portion of the water-stopping wall 2, and a handle 2H etc. is provided on the upper plate 2t as described later.
In other words, in the water-stopping wall 2 of embodiment 16, the upper plate 2t of the wall panel portion 2a functions as the upper end of the water-stopping wall 2, and therefore this upper plate 2t corresponds to the upper plate portion 2e that functions as the upper end of the water-stopping wall 2 described in embodiments 1 to 15.

When the wall panel portion 2a is constructed from a flat plate as in the above-mentioned embodiments 1 to 15, it is preferable to use a thick flat plate in order to increase the strength of the wall panel portion 2a. However, if a thick flat plate is used, the weight of the water-stopping device 1 will increase, which may result in the water-stopping device 1 being difficult to work with (handle) during installation, removal, transportation, and other operations.
On the other hand, as in the sixteenth embodiment, by forming a hollow wall panel 2a by combining shaped members 2m, 2m..., the strength of the wall panel 2a is improved and a waterstop wall 2 having a lightweight wall panel 2a can be constructed. In other words, the strength of the wall panel 2a of the waterstop wall 2 is improved and a waterstop device 1 with good handleability can be provided.
For example, when constructing a water stopping device 1 to correspond to the inner opening 11 of a double-leaf door 9 as shown in FIG. 18, the size of the wall panel portion 2a will be large. Therefore, if a thick flat plate is used as the wall panel portion 2a, the wall panel portion 2a will be large and heavy, which may result in the water stopping device 1 being difficult to work with (handle).
On the other hand, if the configuration is provided with a hollow wall panel portion 2a formed by combining a plurality of shaped members 2m, 2m... as in embodiment 16, even if the size of the wall panel portion 2a is large, the strength of the wall panel portion 2a of the water-stopping wall 2 can be improved and the wall panel portion 2a of the water-stopping wall 2 can be made lighter, making it possible to provide a water-stopping device 1 with good workability (handleability).

EMBODIMENT 17
The upper end of the water-stopping wall 2, i.e., the upper plate 2t of the wall panel portion 2a (the upper plate of the shaped member 2m constituting the uppermost part of the wall panel portion 2a) in the water-stopping wall 2 of embodiment 16, or the upper plate portion 2e of embodiments 1 to 15, is provided with a handle 2H as shown in Figures 16 to 18.
With a water-stopping device 1 equipped with such a handle 2H, a person can easily perform operations such as installation, removal, and transportation of the water-stopping device 1 while holding the handle 2H, thereby making it possible to provide a water-stopping device 1 with good workability (handleability).

EMBODIMENT 18
If a handle 2H is provided at the upper end of the water-stopping wall 2 in the water-stopping device 1, after the water-stopping device 1 has been installed in a specified state in the inner opening 11 of the door frame 10, when the door 9 is closed or when the door 9 is opened from a closed state, there is a possibility that a protrusion that protrudes inside the door 9 beyond the inner surface of the door 9 may interfere with the handle 2H.
Furthermore, the protrusion that protrudes indoors beyond the inner surface of the door 9 is a part that protrudes beyond the inner surface of the door 9 when it is closed and is positioned above the upper end of the water-stopping wall 2, and is, for example, a movable part such as a handle 9N (lever handle) of the door 9 (see Figure 18), a thumb turn, a push-pull lock, or a fixed part such as a cylinder.
Therefore, the waterproof device 1 is provided with a handle 2H that is configured to avoid interference with a protrusion protruding from the inner surface of the door 9 toward the interior side.
That is, the water-stopping device 1 is provided with a handle 2H at the upper end of the water-stopping wall 2, which has a mechanism for avoiding interference with protrusions that protrude inside the door beyond the inner surface of the door 9 when closed, for example, a retractable handle 2H as shown in Figure 19(a), or a vertically movable handle 2H as shown in Figure 19(b), or a rotatable handle 2H as shown in Figure 19(c).

As the collapsible handle 2H, for example, a handle 2H having a configuration as shown in FIG. 20 is provided.
The collapsible handle 2H is configured so that the handle 2H is attached to, for example, an upper plate 2t as the upper end portion of the water blocking wall 2 via mounting bases 2HB, 2HB.
The handle 2H is formed, for example, in a gate shape, and both ends 4a, 4a of the handle 2H are attached to the upper plate 2t of the water blocking wall 2 via mounting bases 2HB, 2HB, respectively, so as to be able to rise and fall.
The mounting base 2HB is fixed to the upper plate 2t by mounting screws or the like (not shown). The handle 2 has both ends 4a, 4a rotatably attached to the mounting bases 2HB, 2HB via a rotation center shaft 4c that forms a rotation center 2R.
The mounting bases 2HB, 2HB are configured to include a restricting surface 4b (see FIG. 20(a)) for maintaining the handle 2 in a vertically upright state above the upper plate 2t, and a restricting surface 4f (see FIG. 20(b)) for maintaining the handle 2 in a laid-down state toward the rear (indoor side). For example, the restricting surface 4b is configured by a surface perpendicular to the flat upper surface of the upper plate 2t, and the restricting surface 4f is configured by a surface parallel to the flat upper surface of the upper plate 2t.
Therefore, when the handle 2H is to be used, the handle 2H is set in an upright position as shown in FIG. 20(a).
In addition, if there is interference between the handle 2H and a protrusion that protrudes indoors beyond the inner surface of the door 9, the interference with the protrusion can be avoided by setting the handle 2H in a laid-down state, as shown in Figure 20 (b).

As the vertically movable handle 2H, for example, a handle 2H as shown in FIG. 21 is provided.
The vertically movable handle 2H has through holes 2g, 2g formed in the upper plate 2t for passing both ends 4a, 4a of the handle 2, and a stopper 4g is provided at the tip side of both ends 4a, 4a of the handle 2 to prevent the ends 4a of the handle 2 from slipping out of the through holes 2g.
Therefore, when using the handle 2H, as shown in Figures 21 (a) and (b), the handle 2H is moved upward until the stoppers 4g, 4g collide with the inner surface (lower surface) of the upper plate 2t.
In addition, when the handle 2H is not in use, as shown in Figures 21 (c) and (d), the handle 2H descends under its own weight, and is set to a state in which it can avoid interference with any protrusions that protrude inside the door beyond the inner surface of the door 9.
Furthermore, if a screw portion 4t is formed on the tip side of both ends 4a, 4a of the handle 2, the retainer 4g can be made of a member such as a nut, and the position of the retainer 4g can be adjusted to adjust the range of vertical movement of the handle 2H.

As the rotating handle 2H, for example, a handle 2H as shown in FIG. 22 is provided.
The rotating handle 2H has one end 4a of both ends 4a, 4a of the handle 2 rotatably attached to the upper plate 2t, and the wall plate portion 2a has an end ingress/egress groove 2h formed therein through which the other end 4a can enter and exit. The end ingress/egress groove 2h is formed so as to straddle the upper plate 2t of the wall plate portion 2a and the wall surface (the wall surface facing the indoor side) 21b.
The tip side of one end 4a is provided with an upper nut 4i that is screwed onto a threaded portion 4t formed on the tip side of the one end 4a and positioned above the upper plate 2t, a washer 4j that is inserted into the threaded portion 4t and positioned below the upper plate 2t, and a lower nut 4k that is inserted into the threaded portion 4t and positioned below the washer 4j.
Then, by loosening the upper nut 4i from the upper plate 2t, the handle 2H is set in a state in which it can rotate around the central axis of one end 4a as the center of rotation 2R.
Furthermore, by fastening the upper nut 4i to the upper plate 2t, the handle 2H is set in a state in which it cannot rotate around the central axis of one end 4a as the center of rotation 2R.
Therefore, when using the handle 2H, the other end 4a is positioned within the end groove 2h as shown in FIG. 22(a), and the upper nut 4i is tightened to set the handle 2H in an unrotatable state before use.
If there is interference between the handle 2H and a protrusion that protrudes indoors beyond the inner surface of the door 9, the upper nut 4i is loosened, one end 4a is rotated around the central axis of the end 4a as the center of rotation 2R, and the other end 4a is moved from within the end entrance groove 2h to the indoor side (rear side), thereby setting it in a state in which interference with the protrusion can be avoided.

As described above, if the water stop device 1 is equipped with a retractable, vertically movable, or rotatable handle 2H as in embodiment 18, for example, when the water stop device 1 is installed so as to block the inner opening 11 of the door frame 10 and the door 9 is closed, it is possible to prevent interference between the handle 2H and any protrusions that protrude further inside the door than the inner surface of the door 9.
Therefore, for example, it is possible to provide a water stop device 1 that can set the height dimension of the water stop device 1 to the height dimension directly below the door handle (lever handle) 9N provided on the inner surface of the door 9, and that can prevent interference between the door handle 9N and the handle 2H when the door handle 9N is operated. For example, in Fig. 18, it is possible to further increase the height dimension of the water stop device 1 to the position directly below the door handle 9N.
Furthermore, the handle 2H may be of a configuration other than the above-mentioned retractable, vertically movable, or rotatable type, so long as it is configured to prevent interference with protrusions that protrude inside the door beyond the inner surface of the door 9 when it is closed.
For example, the handle 2H may be attached to the upper plate 2t so as to be movable in the left-right direction of the upper plate 2t, or may be detachable from the upper plate 2t.

EMBODIMENT 19
A hook portion 2F as shown in Figures 16 to 18 is provided on the upper end portion of the water blocking wall 2, for example, the upper plate 2t of the wall plate portion 2a of the water blocking wall 2 described above, or the upper plate portion 2e of embodiments 1 to 15.
With a water stop device 1 equipped with such a hook portion 2F, the water stop device 1 can be stored in a hanging state on a wall, for example by hooking the hook portion 2F onto a wall hook or the like provided on the wall, and as such storage on the floor can be avoided, there is no need to provide a dedicated floor space for storage.

FIG. 18 shows an example of a waterproofing device 1 having the configurations of the sixteenth to nineteenth embodiments and installed in an inner opening 11.
The water-stopping device 1 has a wall panel portion 2a of a water-stopping wall 2 which is formed of a plate-shaped hollow box body formed by combining a plurality of shapes 2m, 2m such as aluminum extrusion shapes, and has a handle 2H and a hook portion 2F attached to the upper end of the wall panel portion 2a.
It is preferable that the handle 2H and the hook portion 2F are provided on each of the left and right sides of the upper plate 2t of the wall plate portion 2a.

EMBODIMENT 20
The water-stopping device 1 is attached in a fixed state to the left surface 12, right surface 13, bottom surface 14, and top surface 15 of the inner opening 11 of the door frame 10, and when the door 9 is closed, the wall surface (wall surface facing the outdoors) 21a of the wall panel portion 2a of the water-stopping wall 2 does not interfere with any protrusions protruding from the indoor surface of the door 9.
In addition, when the water stop device 1 is installed in the inner opening 11 of the door frame 10 and the door 9 is closed, protrusions that may protrude from the indoor side of the door 9 and come into contact with the wall surface 21a of the wall panel portion 2a of the water stop wall 2 include, for example, the joint between one door 9L and the other door 9R of the double-leaf door 9, the handle 9N (lever handle) of the door 9, a cylinder, a thumb turn, a push-pull lock, etc.

In other words, the water-stopping wall 2 is equipped with the wall panel portion 2a, left side engagement portion 6, right side engagement portion 7, and lower engagement portion 8 as described above, and the length from the left end of the wall surface 21a of the wall panel portion 2a to the left side engagement portion 6, the length from the right end of the wall surface 21a to the right side engagement portion 7, and the length from the bottom end of the wall surface 21a to the lower engagement portion 8 are formed to be the same length, and the length from each end face of the wall surface 21a to each engagement portion is longer than the protruding length of the protrusion that protrudes from the indoor surface of the door 9 in the closed state, thereby forming a water-stopping device 1.
In other words, as shown in Figures 23 and 24, by setting the front-to-rear lengths of the left plate portion 2b, which is provided so as to extend forward from the left edge of the wall surface 21a of the wall panel portion 2a to the left side engagement portion 6, the right plate portion 2c, which is provided so as to extend forward from the right edge of the wall surface 21a of the wall panel portion 2a to the right side engagement portion 7, and the lower plate portion 2d, which is provided so as to extend forward from the lower edge of the wall surface 21a of the wall panel portion 2a to the lower engagement portion 8, to appropriate lengths, a water-stopping device 1 is provided with a water-stopping wall 2 in which the wall surface 21a of the wall panel portion 2a of the water-stopping device 1 installed to block the inner opening 11 of the door frame 10 does not come into contact with any protrusions protruding from the indoor surface of the door 9 when the door 9 is closed.

According to the 20th embodiment, the length of the left panel 2b, the right panel 2c, and the lower panel 2d in the front-rear direction is increased, and the dimension from the wall surface 21a facing the outdoor side (front side) of the wall panel 2a to the left locking portion 6, the right locking portion 7, and the lower locking portion 8 (in other words, the depth dimension of the recess surrounded by the wall surface 21a, which is the bottom surface of the recess, the left panel 2b, the right panel 2c, and the lower panel 2d) is sufficiently longer than the protruding length of the protrusion that protrudes from the indoor side surface of the door 9 in the closed state. Therefore, when the water stop device 1 is attached to the inner opening 11 of the door frame 10 and the door 9 is closed, interference between the wall surface 21a of the wall panel 2a of the water stop wall 2 and the protrusion that protrudes from the indoor side surface of the door 9 can be avoided.

EMBODIMENT 21
As described in embodiment 20, if the front-to-rear width dimension of the water-stopping wall 2 is increased, the front-to-rear width dimensions (hereinafter referred to as width dimension A) of the left end face 22, right end face 23, and lower end face 24 of the water-stopping wall 2 will also be increased.
In this way, when the width dimension A of the water stopping wall 2 is increased, the length of the width dimension A of the water stopping wall 2 may become longer than the length of the width dimension (hereinafter referred to as width dimension B) in the front-to-rear direction of the left surface 12, right surface 13, and bottom surface 14 of the door frame 10. That is, although the length of the width dimension A described above is shorter than the length of the width dimension B in Figures 23 and 24, the length of the width dimension A may be longer than the length of the width dimension B.
As for the water-stopping device 1 to be installed in the inner opening 11 of the door frame 10 formed with a width dimension B shorter than the width dimension A, when the water-stopping device 1 is installed in the inner opening 11 of the door frame 10, it is necessary to have watertightness maintaining means 3, 4, 5 present on the surfaces of the left end face 22, right end face 23 and bottom end face 24 of the water-stopping wall 2 that face the left face 12, right face 13 and bottom face 14 of the door frame 10.

Therefore, in embodiment 21, in order to be able to accommodate cases where the length of width dimension A is longer than the length of width dimension B, and to maintain the watertight performance between the left end face 22, right end face 23, and bottom end face 24 of the water-stopping wall 2 of the water-stopping device 1 and the left face 12, right face 13, and bottom face 14 of the inner opening 11 of the door frame 10, a water-stopping device 1 is provided as follows.
That is, the watertightness maintaining means 3, 4, 5 of the waterstop device 1 are configured to extend to positions near the left engaging portion 6, right engaging portion 7, and lower engaging portion 8 on the left end face 22, right end face 23, and lower end face 24 of the waterstop wall 2.
Alternatively, the watertightness maintaining means 3, 4, 5 are provided only in the vicinity of the left side engaging portion 6, right side engaging portion 7, and lower side engaging portion 8 on the left end face 22, right end face 23, and lower end face 24 of the waterstop wall 2 that face the left face 12, right face 13, and lower face 14 of the inner opening 11 of the door frame 10.
In other words, the water-stopping device 1 is provided with a water-stopping wall 2 that includes a wall panel portion 2a, a left-side engagement portion 6, a right-side engagement portion 7, and a lower engagement portion 8, and watertightness maintaining means 3, 4, and 5 are provided at least in the vicinity of the left-side engagement portion 6 on the left end face 22 of the water-stopping wall 2 that faces the left face 12 of the inner opening 11 of the door frame 10, at least in the vicinity of the right-side engagement portion 7 on the right end face 23 of the water-stopping wall 2 that faces the right face 13 of the inner opening 11 of the door frame 10, and at least in the vicinity of the lower engagement portion 8 on the lower end face 24 of the water-stopping wall 2 that faces the lower face 14 of the inner opening 11 of the door frame 10.

In this case, in order to further improve the watertightness, the watertightness maintaining means 3, 4, 5 provided in the vicinity of the left side engaging portion 6, right side engaging portion 7, and lower side engaging portion 8 on the left end face 22, right end face 23, and lower end face 24 of the waterstop wall 2 are preferably watertightness maintaining means having inclined surfaces 3a, 4a, 5a as watertightness improving means as shown in Figures 4(a), 4(b), and 15, or watertightness maintaining means having protrusions 3a, 4a, 5a as watertightness improving means as shown in Figures 4(c), 4(d), 14, and 24.

As described above, according to embodiment 21, it is possible to provide a watertight device 1 that can handle cases where the length of width dimension A is longer than the length of width dimension B, and that can maintain the watertight performance between the left end face 22, right end face 23, and bottom end face 24 of the waterstop wall 2 and the left face 12, right face 13, and bottom face 14 of the door frame 10 by the watertightness maintaining means 3, 4, and 5.

EMBODIMENT 22
For example, as shown in Figures 23 and 24, in the door frame 10, a peripheral groove 10a formed around the frame on the opening/closing side of the door 9 (i.e., the front side of the door frame 10) is usually provided with a cushioning material 10b called "airtight rubber" or the like in order to prevent direct contact between the door 9 and the door frame 10 and to ensure adhesion between the periphery of the inner surface of the door 9 and the door frame 10.
For this reason, if the front ends 3e, 4e, 5e of the watertightness maintaining means 3, 4, 5 are brought into contact with the left locking portion 6, the right locking portion 7, and the lower locking portion 8, or if an appropriate space is not provided between the front ends 3e, 4e, 5e of the watertightness maintaining means 3, 4, 5 and the left locking portion 6, the right locking portion 7, and the lower locking portion 8, when the door 9 is closed, the cushion material 10b may be crushed and a part of the cushion material 10b may climb over the door abutment surfaces 16, 17, 18 and come into contact with the front ends 3e, 4e, 5e of the watertightness maintaining means 3, 4, 5. In this way, if a part of the cushion material 10b comes into contact with the watertightness maintaining means 3, 4, 5, a gap that serves as a waterway may be formed between the part of the cushion material 10b that is in contact and the watertightness maintaining means 3, 4, 5, and the watertightness performance of the watertightness maintaining means 3, 4, 5 may be impaired.
Therefore, as shown in Figures 23 and 24, appropriate gaps, i.e., interference prevention gaps 3s, 4s, 5s, are provided between the front ends 3e, 4e, 5e of the watertightness maintaining means 3, 4, 5 and the left side engagement portion 6, right side engagement portion 7, and lower engagement portion 8.
In other words, interference prevention gaps 3s, 4s, 5s are provided between the front ends 3e, 4e, 5e, which are ends of the left side engagement portion 6, right side engagement portion 7, lower engagement portion 8 of the watertightness maintaining means 3, 4, 5, and the left side engagement portion 6, right side engagement portion 7, lower engagement portion 8, in order to prevent interference between the watertightness maintaining means 3, 4, 5 and the cushion material 10b.
In other words, in the case where the door frame 10 is provided with a circumferential groove 10a formed around the frame periphery on the opening and closing side of the door 9 to prevent direct contact between the door 9 and the door frame 10 and to ensure close contact between the periphery of the inner side of the door 9 and the door frame 10, the waterstop device 1 is configured so that interference prevention gaps 3s, 4s, 5s are provided between the watertightness maintaining means 3, 4, 5 provided in the vicinity of each engagement portion 6, 7, 8 and each engagement portion 6, 7, 8 to prevent interference between the watertightness maintaining means 3, 4, 5 and part of the cushioning material 10b that deforms when the door 9 is closed.
According to the water-stopping device 1 of embodiment 22, interference between the cushioning material 10b of the door frame 10 and the watertightness maintaining means 3, 4, and 5 of the water-stopping device 1 when the door 9 is closed can be prevented, thereby making it possible to avoid situations in which the watertightness performance is compromised.

EMBODIMENT 23
Due to manufacturing errors, i.e., tolerances, in the door frame 10 and the waterstop device 1, gaps may occur between the left watertightness maintaining means 3 and the left surface 12 of the door frame 10, or between the right watertightness maintaining means 4 and the right surface 13 of the door frame 10, which may result in the watertightness performance between the left watertightness maintaining means 3 and the left surface 12 of the door frame 10, or between the right watertightness maintaining means 4 and the right surface 13 of the door frame 10, not being adequately maintained, and the watertightness performance between the left watertightness maintaining means 3 and the left surface 12 of the door frame 10, or between the right watertightness maintaining means 4 and the right surface 13 of the door frame 10 not being adequately maintained, and the waterstop device 1 may not be securely installed in the inner opening 11 so that it is fixedly sandwiched between the left surface 12 and right surface 13 of the door frame 10.
Therefore, as shown in Figures 25, 26 and 27, the water-stopping device 1 is configured with pressing mechanisms 6A, 6A to press the left plate portion 2b toward the left surface 12 of the inner opening 11 of the door frame 10, or to press the right plate portion 2c toward the right surface 13 of the inner opening 11 of the door frame 10.
That is, the water blocking wall 2 includes a wall panel portion 2a, a left side engaging portion 6, a right side engaging portion 7, and a lower side engaging portion 8. In a left panel portion 2b of the wall panel portion 2a from the left end of the wall surface 21a to the left side engaging portion 6, a left watertightness maintaining member 3 is provided on a left end surface 22 which is a panel surface facing a left surface 12 of the inner opening 11 of the door frame 10. In a right panel portion 2c of the wall panel portion 2a from the right end of the wall surface 21a to the right side engaging portion 7, a right watertightness maintaining member 4 is provided on a right end surface 23 which is a panel surface facing a right surface 13 of the inner opening 11 of the door frame 10. In the water-stopping device 1, a lower watertightness maintaining member 5 is provided on the lower end surface 24 of the lower plate portion 2d from the lower end of the wall surface 21a of the wall panel portion 2a to the lower engaging portion 8, which is the plate surface facing the lower surface 14 of the inner opening 11 of the door frame 10.In the water-stopping device 1, the wall surface 21a located on the door side of the water-stopping wall 2 is provided with a pressing mechanism 6A for pressing the left plate portion 2c against the left surface 12 of the door frame 10, and a pressing mechanism 6A for pressing the right plate portion 2c against the right surface 13 of the door frame 10.

The pressing mechanism 6A for pressing the right plate portion 2c toward the right surface 13 of the door frame 10 includes a mounting base 6a and a pressing member, as shown in Figures 26 and 27 .
The mounting base 6a is constituted, for example, by an L-shaped angle bracket, and one flat plate of the L shape is fixed to the wall surface 21a by a fixing member 6b such as a screw so that the plate surface of the other flat plate of the L shape faces the plate surface of the right plate portion 2c in parallel.
The pressing member is configured with a bolt through hole (not shown) formed to pass through one of the flat plates of the L-shaped angle bracket, a bolt 6c, and a nut 6d. The nut 6d is fixed to the plate surface of one of the flat plates by a fixing means such as welding so that the screw hole of the nut 6d is continuous with the bolt through hole formed in the plate surface of the one of the flat plates of the L-shaped angle bracket facing the left surface 12 in parallel.
The bolt 6c passes through a bolt through hole (not shown) and a threaded hole in the nut 6d, and the pressing end 6e formed by the tip of the bolt 6c is configured to be able to move forward and backward in a direction approaching the right plate portion 2c and in a direction away from the right plate portion 2c.
The pressing mechanism 6A for pressing the left plate portion 2c toward the left surface 12 of the door frame 10 is configured such that one flat plate of the L-shaped L-shaped angle bracket constituting the mounting base 6a faces the other flat plate of the left plate portion 2b in parallel with one flat plate of the L-shaped L-shaped angle bracket, and is fixed to the wall surface 21a with a fixing member 6b such as a screw. The bolt 6c passes through a bolt through-hole (not shown) and a screw hole of the nut 6d, and a pressing end 6e formed by the tip of the bolt 6c can advance and retreat in a direction approaching the left plate portion 2b and in a direction away from the left plate portion 2b.
25, it is preferable to provide a plurality of pressing mechanisms 6A at predetermined intervals along the up-down direction of the left plate portion 2b and the right plate portion 2c. This configuration is preferable because it is possible to press the entire left plate portion 2b and the entire right plate portion 2c almost evenly using the plurality of pressing mechanisms 6A, 6A.

According to the water-stopping device 1 of embodiment 23, even if a gap occurs between the left watertightness maintaining means 3 and the left surface 12 of the door frame 10, or between the right watertightness maintaining means 4 and the right surface 12 of the door frame 10, due to the tolerance of the door frame 10 and the water-stopping wall 1, the pressing mechanism 6A can press the left plate portion 2b toward the left surface 12 of the door frame 10, or press the right plate portion 2c toward the left surface 12 of the door frame 10, thereby improving the adhesion between the left watertightness maintaining means 3 and the left surface 12 of the door frame 10, or between the right watertightness maintaining means 4 and the right surface 13 of the door frame 10.
Therefore, it is possible to provide a water-stopping device 1 that can be reliably installed in the inner opening 11 so as to be fixed by being sandwiched between the left surface 12 and the right surface 13 of the door frame 10, while being able to accommodate the tolerances of the door frame 10 and the water-stopping wall 1 and to adequately maintain the water-tightness performance between the left water-tightness maintaining means 3 and the left surface 12 of the door frame 10, and the water-tightness performance between the right water-tightness maintaining means 4 and the right surface 13 of the door frame 10.
In other words, according to embodiment 23, it is possible to provide a water-stopping device 1 that can improve the effect of maintaining watertightness and the reliability of installation by adapting to the tolerances of the door frame 10 and the water-stopping wall 1.
In addition, the influence of the deterioration of the watertightness maintaining means 3, 4 over time, which reduces the effect of maintaining the watertightness performance, can be reduced.

As shown in FIG. 27, if a pressure member 6f having a pressing end (pressing surface) 6e with a diameter larger than the area of the pressing end 6e formed by the tip of the bolt 6c is provided on the tip side of the bolt 6c, the pressing end (pressing surface) 6e can be easily used to uniformly press the entire left plate portion 2b or the entire right plate portion 2c, thereby improving the effect of maintaining watertightness and the reliability of installation.

In addition, in a configuration that includes the surface pressure member 6f, the surface pressure member 6f may be attached to the tip side of the bolt 6c so that the bolt 6c is fixed to the mounting base 6a and the surface pressure member 6f itself can move forward and backward in a direction toward the left plate portion 2b and the right plate portion 2c and in a direction away from the left plate portion 2b and the right plate portion 2c.

EMBODIMENT 24
As shown in Figures 28 and 29, the water stop device 1 is configured to include a support section for supporting accurate and reliable installation work of the water stop device 1, and an installation work support section 99 that also functions as a reinforcing device for reinforcing the lower engagement section 8 and the lower plate section 2d.
In other words, the water-stopping wall 2 has a wall panel portion 2a, a left side engagement portion 6, a right side engagement portion 7, and a lower engagement portion 8, and the upper surface of the lower panel portion 2d from the lower end of the wall surface 21a of the wall panel portion 2a to the lower engagement portion 8 is provided with an installation work support portion 99 for supporting the installation work of the water-stopping device 1.

The installation work support portion 99 is formed using, for example, synthetic resin such as hard polyvinyl chloride (H-PVC), rubber, or the like.
The installation work support part 99 may be provided on the upper surface of the lower plate part 2d along the entire left-right length between the left plate part 2b and the right plate part 2c, as shown in Figures 28 and 29(b), or may be provided intermittently along the left-right length between the left plate part 2b and the right plate part 2c, as shown in Figure 29(c).
The installation work support part 99 is composed of a long rod-shaped member having a right-angled triangular cross-section, for example, a lower surface 99a facing the upper surface of the lower plate part 2d, a back surface 99b extending upward from the rear edge of the lower surface 99a and facing the front wall surface 21a of the wall plate part 2a, and an inclined surface 99s connecting the upper edge of the back surface 99b and the front edge of the lower surface 99a.
The inclined surface 99s is formed, for example, by an uneven surface having repeated projections and recesses along the inclination direction.
The installation work support part 99 is configured to be integrated with the water blocking wall 2, for example, by bonding the opposing lower surface 99a to the upper surface of the lower plate part 2d with an adhesive or the like and by bonding the opposing back surface 99b to the front wall surface 21a of the wall plate part 2a with an adhesive or the like. Note that only the opposing lower surface 99a and the upper surface of the lower plate part 2d may be bonded with an adhesive or the like, or only the opposing back surface 99b and the front wall surface 21a of the wall plate part 2a may be bonded with an adhesive or the like.

In the case of a water stopping device 1 not having the installation operation support unit 99, when installing the water stopping device 1 at the inner opening 11, if there is a high degree of adhesion between the left watertightness maintaining means 3 and the left surface 12 of the door frame 10 and between the right watertightness maintaining means 4 and the right surface 13 of the door frame 10, simply pressing down the water stopping device 1 by hand will make it difficult to effectively apply force F downward, as shown in Figure 30(a), and the lower end side of the water stopping device 1 may not be installed accurately in the specified position. For example, the water stopping device 1 may be installed in a state where the watertightness maintaining means 5 on the lower side and the lower surface 15 of the door frame 10 are not in close contact, and watertightness performance may not be maintained.
On the other hand, in the case of the water stop device 1 having the installation work support part 99 according to the twenty-fourth embodiment, when installing the water stop device 1 in the inner opening 11, the worker steps on the installation work support part 99 with his/her foot as shown by the outline arrow F in Fig. 30(b), so that the force pressing down on the water stop device 1 is reliably transmitted to the water stop device 1, and the lower end side of the water stop device 1 is accurately installed in a predetermined position. In other words, the watertightness maintaining means 5 on the lower side of the water stop device 1 and the lower surface 15 of the door frame 10 are installed in a state of close contact with each other, so that the watertightness performance can be fully exhibited.
In other words, according to the water stopping device 1 of embodiment 24, accurate installation of the water stopping device 1 relative to the inner opening 11 of the door frame 1 can be performed reliably and easily.

Furthermore, in the case of a water stop device 1 that is not equipped with an installation work support unit 99, if the water stop device 1 is dropped onto a surface S such as the ground, a floor, or the surface of a stand for some reason, as shown by arrow D in Figure 30 (c), the lower engagement portion 8 and the lower plate portion 2d may be bent and damaged.
On the other hand, according to a water-stopping device 1 configured with an installation work support part 99 of embodiment 24, if the water-stopping device 1 is dropped onto a surface S, as shown by arrow D in Figure 30 (d), the installation work support part 99 functions as a reinforcing part for the lower engagement part 8 and the lower plate part 2d, so that it is possible to provide a water-stopping device 1 in which the lower engagement part 8 and the lower plate part 2d are less likely to be damaged.

It goes without saying that the water stop device 1 according to the present invention may be configured by combining two or more of the configurations of each of the above-mentioned embodiments 1 to 24.
