Description

The present invention relates to a mounting structure for a switching device and a rainwater receiver for the switching device.

Window shutters that are installed in openings in building frameworks are known (see Patent Document 1). In these window shutters, the shutter is fixed to the building framework. The shutter case is attached to a case base frame that is composed of an upper frame, left and right vertical frames, and a lower frame and is fixed to a structural body. For this reason, the shutter case is not fixed to the outer surface of the exterior wall material. Because this type of window shutter can fix the shutter case to the building framework, it is easy to prevent rainwater from entering between the shutter curtain and the window glass of the sash. However, if you want to install a shutter device later after the exterior wall material has been installed on the building framework, or if the building is already built, the shutter case must be attached to the exterior wall surface.

Patent Document 2 proposes a waterproof structure for a shutter that is attached to an exterior wall after an exterior wall material has been installed or when a building is already in place. In this waterproof structure for an exterior wall-mounted shutter, a long reinforcing plate is provided along the upper case plate of the shutter case. The reinforcing plate has an upper vertical reinforcing piece that abuts against the vertical piece of the upper case plate from the exterior wall side. According to this waterproof structure for an exterior wall-mounted shutter, a dry sealant is used as the sealant, and the dry sealant is elastically deformed into a thin shape using the vertical reinforcing piece of the reinforcing plate to form a waterproof structure, which is said to provide a waterproof structure with stable quality.

However, the structure of the exterior wall of a building is often not uniformly smooth, but has a design element; for example, some exterior walls are covered with tiles, and some have uneven surfaces due to the design. When fixing a shutter case to such an existing exterior wall surface, recesses caused by tile joints or patterns must be filled with caulking or sealant. However, if the caulking is insufficient, or if deterioration occurs over time, rainwater may flow through the joints between the exterior wall surface and the shutter case and enter between the shutter curtain of the window shutter and the sash window of the opening. In such a situation, rainwater does not enter the interior of the building due to the presence of the sash window, but there is a risk of rainwater adhering to the outer glass surface of the sash window even when the shutter curtain is closed, which can cause problems.

The present invention was made in consideration of the above situation, and its purpose is to provide an opening and closing device mounting structure and a rainwater receiver for the opening and closing device that can prevent rainwater from entering and adhering to the outer surface of the window glass, etc.

Next, means for solving the above problems will be described with reference to the drawings corresponding to the embodiments.
The mounting structure for an opening and closing device according to the first aspect of the present invention comprises an exterior wall material 19 fixed to a body 51 and having an exterior material 57 on an outer surface thereof;
A fitting frame 21 is disposed at the boundary between the opening 13 provided in the body 51 and the exterior wall material 19;
A drip edge 71 having a hanging piece 75 formed in a long length along the upper side portion 23 of the door frame 21 and bending and hanging down from between the body 51 and the exterior wall material 19 to the outside of the upper side portion 23;
a storage section 31 for storing an opening/closing body 15 that is formed in a long shape along the upper side portion 23 and is fixed to the body 51 from the outside of the exterior material 57 and covers the opening 13;
a rainwater receiver 73 for an opening/closing device, which is disposed between the opening/closing body 15 extended from the storage section 31 and the upper side section 23, being longer than the upper side section 23, and which has an upper side shaped as a receiving opening 81, and in which a hanging piece 75 of the drain 71 is disposed in the receiving opening 81;
a pair of outer frames 41 each having a hollow portion 93 and formed long along the left and right vertical side portions 25 of the door frame 21 sandwiching the opening 13, each having a guide rail 49 for guiding both the left and right side portions of the opening/closing body 15, and fixed to the body 51 from the outside of the exterior material 57, and having an insertion opening 97 for inserting at least one longitudinal end portion 95 of the opening/closing device rainwater receiver 73;
The present invention is characterized by comprising:

In this mounting structure for the opening/closing device, rainwater droplets that flow downward between the storage section 31 and the exterior material 57, between the exterior material 57 and the exterior wall material 19, and between the exterior wall material 19 and the structure 51 are first received by the upper surface of the drain 71, and then fall from the hanging piece 75 provided on the drain 71. The water droplets fall to the receiving port 81 of the opening/closing device rainwater receiver 73. The water droplets that fall from the hanging piece 75 are received by the receiving port 81 and flow along the opening/closing device rainwater receiver 73 to the longitudinal end 95 of the opening/closing device rainwater receiver 73. The end 95 of the opening/closing device rainwater receiver 73 is inserted into at least one of a pair of outer frames 41 that are arranged on the left and right sides of the opening 13. The outer frame 41 has a hollow portion 93. Therefore, water droplets falling from the end 95 of the opening/closing device rainwater receiver 73 flow through the hollow portion 93 to the lower end of the outer frame 41, and are finally drained from the outer frame 41 to the outside of the surface of the exterior material 57. In this way, the water droplets received by the drain 71 are received by the opening/closing device rainwater receiver 73, which is longer than the upper side portion 23 of the door frame 21, and are discharged to the outside by the outer frame 41 from its end 95. In other words, rainwater does not flow between the closed opening/closing body 15 and the window (sash window 29) attached to the door frame 21 between the pair of left and right vertical side portions 25 of the door frame 21. As a result, the opening/closing device mounting structure can suppress rainwater from entering and adhering to the window glass surface, etc.

The mounting structure for a switchgear according to claim 2 of the present invention is the mounting structure for a switchgear according to claim 1,
The opening/closing device rainwater receiver 73 is characterized in that an outer plate portion 83 on the opposite side to the upper side portion 23 across the receiving opening 81 is fixed to the storage portion 31 side.

In this mounting structure of the opening and closing device, the opening and closing device rainwater receiver 73 is shaped so that the upper side becomes the receptacle 81. Therefore, the opening and closing device rainwater receiver 73 has an outer plate portion 83 on the outside with the receptacle 81 in between, and an inner plate portion 91 on the side of the frame 51. In this mounting structure of the opening and closing device, the outer plate portion 83 of the opening and closing device rainwater receiver 73 is fixed to the storage section 31 side located above, for example, the lower surface 37 or side surface. By fixing the opening and closing device rainwater receiver 73 to the storage section 31 side, the receptacle 81 is positioned below the hanging piece 75 of the drip edge 71. Meanwhile, the inner plate portion 91 on the opposite side of the outer plate portion 83 with the receptacle 81 in between is positioned close to or in close contact with the upper edge portion 23 of the fitting frame 21. This allows the water droplets that fall from the hanging piece 75 of the drip edge 71 to be received in the receiving hole 81 without drilling holes in the fitting frame 21, preventing rainwater from entering and adhering to the window glass surface, etc.

The mounting structure for a switchgear according to claim 3 of the present invention is the mounting structure for a switchgear according to claim 1 ,
The rainwater receiver 73 for the opening and closing device is characterized in that an inner plate portion 91 facing an outer plate portion 83 on the opposite side of the upper edge portion 23 across the receiving opening 81 is closely attached to the upper edge portion 23 and fixed to the main body 51 side.

In this opening and closing device mounting structure, the inner plate portion 91 of the opening and closing device rainwater receiver 73 is fixed to the frame 51 side in close contact with the upper side portion 23. Here, the frame 51 side refers to the upper side portion 23 of the door frame 21, or the frame 51 itself. Also, the door frame refers to the sash frame 21 (i.e., the upper side portion 23) to which the sash window 29 is attached, or other door and window. The opening and closing device rainwater receiver 73 is shaped so that the upper side forms a receiving port 81, for example, the cross section in the direction perpendicular to the longitudinal direction is U-shaped, V-shaped, U-shaped, or the like.
As a result, in the mounting structure of the opening and closing device, the inner plate portion 91 of the rainwater receiver 73 for the opening and closing device is closely attached to the upper edge portion 23 and fixed to the main body 51, so that the receiving port 81 is positioned below the hanging piece 75 of the drain 71 with no gap between the inner plate portion 91 and the upper edge portion 23.

The mounting structure for an opening and closing device according to the fourth aspect of the present invention includes an exterior wall material 19 fixed to a body 51 and having an exterior material 57 on an outer surface thereof;
A fitting frame 21 is disposed at the boundary between the opening 13 provided in the body 51 and the exterior wall material 19;
A drip edge 71 having a hanging piece 75 formed in a long length along the upper side portion 23 of the door frame 21 and bending and hanging down from between the body 51 and the exterior wall material 19 to the outside of the upper side portion 23;
a storage section 31 for storing an opening/closing body 15 that is formed in a long shape along the upper side portion 23 and is fixed to the body 51 from the outside of the exterior material 57 and covers the opening 13;
a rainwater receiver 73 for an opening/closing device, which is disposed between the opening/closing body 15 extended from the storage section 31 and the upper side section 23, being longer than the upper side section 23, and which has an upper side shaped as a receiving opening 81, and in which a hanging piece 75 of the drain 71 is disposed in the receiving opening 81;
A pair of outer frames 41 each having a guide rail 49 for guiding the left and right side portions of the opening/closing body 15, which are formed long along the left and right vertical side portions 25 of the door frame 21 that sandwich the opening 13, and which are fixed to the main body 51 from the outside of the exterior material 57 and arranged with a gap 99 from both ends of the opening/closing device rainwater receiver 73 in the longitudinal direction;
The present invention is characterized by comprising:

The opening and closing device rainwater receiver 73 is shaped so that the upper side forms a receiving opening 81, and the hanging piece 75 of the drain 71 is disposed in the receiving opening 81. In other words, water droplets that flow downward between the storage section 31 and the exterior material 57, between the exterior material 57 and the exterior wall material 19, and between the exterior wall material 19 and the building structure 51 are once received by the upper surface of the drain 71, and then drop from the hanging piece 75 provided on the drain 71.
The receiving port 81 of the opening/closing device rainwater receiver 73 is disposed at the destination of the water droplets. The water droplets that have fallen from the hanging piece 75 are received by the receiving port 81 and flow along the opening/closing device rainwater receiver 73 to an end 95 in the longitudinal direction of the opening/closing device rainwater receiver 73. The end 95 of the opening/closing device rainwater receiver 73 is disposed with a gap 99 between a pair of outer frames 41 disposed on the left and right sides of the opening 13. Therefore, the water droplets that have fallen from the end 95 of the opening/closing device rainwater receiver 73 flow mainly along the outer frame 41 to the lower end of the outer frame 41 between the vertical side portion 25 of the fitting frame 21 and the outer frame 41, and are finally drained outside the surface of the exterior material 57.
In this way, the water droplets received by the drain 71 are received by the opening/closing device rainwater receiver 73, which is longer than the upper side 23 of the door frame 21, and flow down from its end 95 along the outer frame 41 and are discharged to the outside. In other words, rainwater will not flow between the closed opening/closing body 15 and the sash window 29 attached to the door frame 21 between the pair of left and right vertical side portions 25 of the door frame 21.

The rainwater receiver 73 for an opening and closing device according to the fifth aspect of the present invention comprises an exterior wall material 19 fixed to a frame 51 and having an exterior material 57 on an outer surface thereof;
A fitting frame 21 is disposed at the boundary between the opening 13 provided in the body 51 and the exterior wall material 19;
A drip edge 71 having a hanging piece 75 formed in a long length along the upper side portion 23 of the door frame 21 and bending and hanging down from between the body 51 and the exterior wall material 19 to the outside of the upper side portion 23;
a storage section 31 for storing an opening/closing body 15 that is formed in a long shape along the upper side portion 23 and is fixed to the body 51 from the outside of the exterior material 57 and covers the opening 13;
A pair of outer frames 41 each having a hollow portion 93, formed in a long length along the left and right vertical side portions 25 of the door frame 21 sandwiching the opening 13, each having a guide rail 49 for guiding both left and right side portions of the opening/closing body 15, and fixed to the body 51 from the outside of the exterior material 57;
A rainwater receiver 73 for a switchgear used in a mounting structure for a switchgear comprising:
The drip tray 71 is characterized in that it is positioned between the opening/closing body 15 extended from the storage section 31 and the upper edge portion 23, being longer than the upper edge portion 23, and the hanging piece 75 of the drip tray 71 is positioned in the receiving opening 81, the upper side of which is shaped to form the receiving opening 81.

In this rainwater collector 73 for opening and closing device, water droplets that flow downward between the storage section 31 and the exterior material 57, between the exterior material 57 and the exterior wall material 19, and between the exterior wall material 19 and the main body 51 are first received on the upper surface of the drain 71 and then fall from the hanging piece 75 provided on the drain 71.
The receiving port 81 of the opening/closing device rainwater receiver 73 is disposed at the destination of the water droplets. The water droplets that have fallen from the hanging piece 75 are received by the receiving port 81 and flow along the opening/closing device rainwater receiver 73 to an end 95 in the longitudinal direction of the opening/closing device rainwater receiver 73. The end 95 of the opening/closing device rainwater receiver 73 may be inserted into one of a pair of outer frames 41 disposed on the left and right sides of the opening 13. The outer frame 41 has a hollow portion 93. Therefore, the water droplets that have fallen from the end 95 of the opening/closing device rainwater receiver 73 flow through the hollow portion 93 to the lower end of the outer frame 41, and are finally drained from the outer frame 41 to the outside of the surface of the exterior material 57.
In this way, the water droplets received by the drain 71 are received by the opening/closing device rainwater receiver 73, which is longer than the upper side 23 of the door frame 21, and are discharged from its end 95 along the outer frame 41 to the outside, or if the end 95 is inserted into the outer frame 41, are discharged to the outside through the hollow portion 93 of the outer frame 41. In other words, rainwater will not flow between the closed opening/closing body 15 and the sash window 29 attached to the door frame 21, between the pair of left and right vertical side portions 25 of the door frame 21.

According to the mounting structure for the opening and closing device described in claim 1 of the present invention, water droplets are received in the rainwater receiver for the opening and closing device, and rainwater does not flow between the closed opening and closing body and the window of the door frame, and rainwater can be prevented from entering and adhering to the outer surface of the window glass, etc.

According to the mounting structure for the opening and closing device described in claim 2 of the present invention, the rainwater receiver for the opening and closing device can be fixed to the storage section side of the opening and closing device, making it unnecessary to provide a fixing means on the building side. In addition, there is no need to drill holes on the building side.

According to the mounting structure for the opening and closing device described in claim 3 of the present invention, the receiving port can be placed below the hanging piece of the drip edge with no gap between the inner plate portion of the opening and closing device rainwater receiver and the upper edge portion of the door frame.

According to the mounting structure for the opening and closing device described in claim 4 of the present invention, rainwater can be made to flow down along the outer frame of the opening and closing device that is positioned outside the door frame, so that rainwater can be prevented from entering and adhering to the outer surface of the window glass, etc.

FIG.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing the appearance of a window shutter 11 equipped with an opening and closing device mounting structure according to this embodiment.
The mounting structure of an opening and closing device according to this embodiment will be described by taking as an example a case in which the opening and closing device is a window shutter 11. The window shutter 11 allows an opening 13 (see FIG. 4 ) provided in a building frame 51 to be freely opened and closed by an opening/closing body, a shutter curtain 15. The shutter curtain 15 is configured in a planar shape in which slats 17 that are long in the width direction of the opening 13 are movably connected at their long sides and can be rolled up.

The opening 13 to which the window shutter 11 is attached has a fitting frame provided on the inside. The fitting frame is provided at the boundary between the opening 13 and the exterior wall material 19 (see FIG. 2) that constitutes the exterior wall of the building. In this embodiment, the fitting frame is a sash frame 21. The sash frame 21 has an upper side portion 23 (see FIG. 2) that extends in the width direction at the top of the opening 13, a pair of vertical side portions 25 (see FIG. 4) that sandwich the opening 13 from the left and right and extend in the vertical direction, and a threshold portion 27 that connects the lower ends of the pair of vertical side portions 25. A sash window 29 with a glass surface that can pass by is attached to the threshold portion 27 in the sash frame 21.

The window shutter 11 has a storage section 31 attached along the upper edge 23 to the outer surface of the exterior wall material 19 above the upper edge 23 of the sash frame 21. The storage section 31 is formed long along the upper edge 23 and is fixed to the body 51 from the outside of the exterior wall material 19, and rolls up and stores the shutter curtain 15 that covers the opening 13. The window shutter 11 is formed on the underside 37 (see Figure 3) of the storage section 31 by rotating the winding section 35 (see Figure 2) of the shutter curtain 15 with an opening/closing device 33 (see Figure 2) provided in the storage section 31, and the shutter curtain 15 is unrolled from a long slit-shaped curtain entrance/exit 39 (see Figure 2) along the upper edge 23 and is also rolled up and stored.

A pair of outer frames 41, which are components of the window shutter 11, are provided on both the left and right ends of the storage section 31 in the longitudinal direction, sandwiching the opening 13 from the left and right. The lower ends of the pair of outer frames 41 are connected by a bottom frame 43. This bottom frame 43 is in contact with a drain slat 45 attached to the lower end of the shutter curtain 15 when the opening 13 is closed. The surface of the bottom frame 43 serves as a bottom frame drain 47 that guides rainwater from the sash window 29, threshold 27, and shutter curtain 15 to the outside of the exterior wall material 19 and drops it down.

FIG. 2 is a vertical cross-sectional view of the vicinity of the storage section shown in FIG.
The window shutter 11 has a pair of guide rails 49 on opposing surfaces of each outer frame 41 that guide the shutter curtain 15, which enters and exits through the curtain entrance 39 of the storage section 31 to open and close the opening 13, so that the shutter curtain 15 can be raised and lowered. In a building with a wooden frame structure, for example, the framework is a structural framework 51 including pillars, studs, girder beams, lintels, and window sills. An exterior wall material 19 is attached to the structural framework 51. A waterproof sheet (not shown) is stretched between the exterior wall material 19 and the structural framework 51.

In this embodiment, the exterior wall material 19 has furring strips 53 and splints, a base material 55, and an exterior material 57. The exterior material 57 is, for example, a tile (see FIG. 5). The exterior wall material 19 may be a building material having a tile-shaped exterior material 57 on its outer surface, or another building material having an uneven design on its outer surface, such as a brick or siding material. The tiles are attached to the base material 55 by a dry or wet construction method. Vertical joints 59 and horizontal joints 61 (see FIG. 5) are provided between adjacent tiles attached to the base material 55 in the left, right, top, and bottom directions to prevent the tiles from cracking due to distortion of the structure during an earthquake, for example. In addition, the vertical joints 59 and horizontal joints 61 may be formed on the outer surface as a design such as a pattern.

The storage section 31 of the window shutter 11 is fixed to the structural body 51 by fasteners 63, such as nails or screws, that penetrate the exterior wall material 19. A seal section 65 that provides a watertight seal between the exterior material 57 and the storage section 31 is provided on the upper surface of the storage section 31 along the longitudinal direction of the storage section 31. The seal section 65 provides a watertight seal between the surface of the exterior material 57 and the mounting base plate 67, for example, by filling the inside of a groove formed on the upper end of the mounting base plate 67 of the storage section 31 with caulking agent 69.

FIG. 3 is an enlarged view of the essential portion in the vicinity of the drain in FIG.
The mounting structure for an opening and closing device according to this embodiment mainly comprises an exterior wall material 19, a sash frame 21, a drain 71, a storage section 31, an opening and closing device rainwater receiver 73, and an outer frame 41. As described above, the exterior wall material 19 is fixed to the structural body 51 and has an exterior material 57 on its outer surface. The sash frame 21 is made up of an upper side portion 23, a vertical side portion 25, and a threshold portion 27, and is disposed at the boundary between the exterior wall material 19 and an opening 13 provided in the structural body 51.

The water cutter 71 is formed in a long length along the upper edge 23 of the sash frame 21. The water cutter 71 has a hanging piece 75 that bends and hangs down from between the structural body 51 and the exterior wall material 19 to the outside of the upper edge 23. The hanging piece 75 of the water cutter 71 is connected to the lower end of the inclined piece 77. The upright piece 79 is connected to the upper end of the inclined piece 77. The water cutter 71 is fixed to the structural body 51 by inserting the upright piece 79, for example, between the waterproof sheet and the structural body 51. The area between the inclined piece 77 and the lower end of the exterior wall material 19, such as the furring strip 53 and the base material 55, is waterproof sealed with a caulking agent 69. In other words, rainwater outside the waterproof sheet is guided by the inclined piece 77 to the hanging piece 75, and is discharged from the lower end of the hanging piece 75 to the outside of the sash frame 21.

The opening/closing device rainwater receiver 73 is disposed between the shutter curtain 15 extended from the storage section 31 and the upper edge section 23, being longer than the upper edge section 23. The opening/closing device rainwater receiver 73 has a receiving port 81 on the upper side. The opening/closing device rainwater receiver 73 has a cross-sectional shape perpendicular to the longitudinal direction that is U-shaped, with the receiving port 81 facing upward. The hanging piece 75 of the drain 71 is disposed above this receiving port 81. In other words, the water droplets W that fall from the hanging piece 75 of the drain 71 are received by the receiving port 81. The cross-sectional shape of the opening/closing device rainwater receiver 73 may be any shape that has a receiving port 81 on the upper side, and may be any shape that has a recess such as a V-shape or U-shape other than the U-shape described above.

The rainwater receiver 73 for the opening and closing device has an outer plate portion 83, which is on the opposite side of the upper edge portion 23 across the receiving opening 81, fixed to the storage section 31 side, for example, the bottom surface 37 or side surface, in this embodiment, the bottom surface 37 of the storage section 31. A fixing piece 85 is formed on the upper end of the outer plate portion 83, which is parallel to the bottom surface 37 of the storage section 31 and bent outward. A lintel 87 is provided on the bottom surface 37 of the storage section 31 and is configured integrally with the storage section 31. In this embodiment, the fixing piece 85 is fixed to the bottom surface of the lintel 87 by a fixing member 89, for example, a rivet or a screw.

The opening/closing device rainwater receiver 73 has an inner plate portion 91 that faces the outer plate portion 83. This inner plate portion 91 is close to or in close contact with the upper edge portion 23 of the sash frame 21. The opening/closing device rainwater receiver 73 may be fixed to the structural body 51 side with this inner plate portion 91 in close contact with the upper edge portion 23.

In addition, when the width of the opening 13 is large, the opening/closing device rainwater collector 73 may be divided into multiple parts in the longitudinal direction, which corresponds to the width direction. In this case, the ends of adjacent opening/closing device rainwater collectors 73 are connected to each other, for example, by a connecting member (not shown). The connecting member connects the ends to each other, for example, on the outer periphery of the opening/closing device rainwater collector 73, so that rainwater entering from the receiving port 81 can flow down without stagnating. Note that such a divided structure makes it easier to install the opening/closing device rainwater collector 73 between the narrow part between the shutter curtain 15 and the upper edge part 23 when incorporating it into an existing window shutter.

FIG. 4 is an enlarged cross-sectional plan view of a main portion near an insertion opening provided in the outer frame 41. As shown in FIG.
The outer frame 41 described above has a hollow portion 93. The outer frame 41 is formed long and aligned along the left and right vertical side portions 25 of the sash frame 21 that sandwich the opening 13. Each outer frame 41 has a guide rail 49 that guides both the left and right side portions of the shutter curtain 15. The outer frame 41 is fixed to the structural body 51 from the outside of the exterior material 57. An insertion opening 97 is formed in at least one of the left and right outer frames 41 corresponding to at least one longitudinal end 95 of the opening/closing device rainwater receiver 73 so that the end 95 can be inserted.

FIG. 5 is an exploded perspective view of essential parts, which shows the drain 71, the opening/closing device rainwater receiver 73, and the outer frame 41 in a simplified manner.
The opening/closing device rainwater receiver 73 does not need to have a gradient to allow rainwater to flow down. Of course, the opening/closing device rainwater receiver 73 may have a gradient in either or both of the longitudinal directions. The opening/closing device rainwater receiver 73 may have both longitudinal ends 95 inserted into the insertion openings 97 formed in the pair of left and right outer frames 41. The opening/closing device rainwater receiver 73 is attached along the upper edge portion 23 of the sash frame 21, so that the water droplets W falling from the drain 71 do not enter the opening 13. That is, the opening/closing device rainwater receiver 73 can receive the water droplets W falling from the drain 71 and drain them into the hollow portion 93 in at least one of the outer frames 41 on the left and right of the opening 13 for discharge.

FIG. 6 is an enlarged plan view of the storage section 31 as viewed from above.
As described above, the storage section 31 of the window shutter 11 penetrates the exterior wall material 19 and is fixed to the structural frame 51. At that time, if an exterior material 57 such as tiles is attached to the outer surface of the exterior wall material 19 and vertical joints 59 and horizontal joints 61 are present, a gap due to the vertical joints 59 and horizontal joints 61 will be generated between the mounting base plate 67 of the storage section 31 and the exterior material 57. This gap is filled with a caulking agent 69 or the like, but it is considered that the waterproof performance will become insufficient due to improper filling or shrinkage (shrinkage) of the caulking agent 69 due to deterioration over time.

Even though the caulking agent 69 is filled in, the mounting structure of the opening and closing device can cause slight gaps to exist between the mounting base plate 67 of the storage section 31 and the exterior wall material 19, causing rainwater to pass through and flow down. However, the water is received by the drain 71 and falls from the hanging piece 75 of the drain 71. The water droplets W that fall from the hanging piece 75 are received by the opening and closing device rainwater receiver 73 located below. The water droplets W received by the opening and closing device rainwater receiver 73 pass through the hollow portion 93 of one of the outer frames 41 provided on the left and right of the opening 13 and are discharged to the outdoors.

The rainwater receiver 73 for the opening and closing device according to this embodiment comprises an exterior wall material 19 fixed to a structural body 51 and having an exterior material 57 on its outer surface, a sash frame 21 arranged at the boundary between an opening 13 provided in the structural body 51 and the exterior wall material 19, a drain 71 formed in a long length along the upper edge portion 23 of the sash frame 21 and having a hanging piece 75 that curves and hangs down from between the structural body 51 and the exterior wall material 19 to the outside of the upper edge portion 23, a storage section 31 formed in a long length along the upper edge portion 23 and fixed to the structure from the outside of the exterior material 57 to store a shutter curtain 15 that covers the opening 13, and a hollow section 93. A rainwater receiver 73 for an opening/closing device used in an installation structure for an opening/closing device, which includes a pair of outer frames 41 fixed to the structural body 51 from the outside of the exterior material 57, each of which has guide rails 49 formed long along the left and right vertical sides 25 of the sash frame 21 that sandwich the opening 13 and guide the left and right sides of the shutter curtain 15, and is arranged between the shutter curtain 15 that is unrolled from the storage section 31 and the upper side 23, longer than the upper side 23, with the upper side forming a receiving opening 81, for example, a U-shaped cross section, and a hanging piece 75 is arranged in the receiving opening 81.

FIG. 7 is an enlarged plan sectional view of a main portion of a modified example in which gaps 99 are provided between both longitudinal ends of the opening/closing device rainwater receiver 73 and the outer frame 41.
In addition, the opening/closing device mounting structure does not require the end 95 of the opening/closing device rainwater receiver 73 to be inserted into the insertion opening 97 of the outer frame 41. That is, the outer frame 41 does not have the insertion opening 97. In the opening/closing device mounting structure according to this modification, the outer frame 41 is formed long along the left and right vertical side portions 25 of the sash frame 21 that sandwich the opening 13, and each of the outer frames 41 is provided with guide rails 49 that guide the left and right side portions of the shutter curtain 15, and is fixed to the structural body 51 side from the outside of the exterior material 57, and is disposed with gaps 99 from both ends of the longitudinal direction of the opening/closing device rainwater receiver 73. As described above, the opening/closing device rainwater receiver 73 has the fixing piece 85 fixed to the underside of the lintel 87 by the fixing member 89 (see FIG. 3).

Next, we will explain the operation of the above configuration.

In the mounting structure for the opening and closing device according to this embodiment, the opening and closing device rainwater receiver 73 is disposed between the shutter curtain 15 extended from the storage section 31 and the upper edge section 23. The opening and closing device rainwater receiver 73 is longer than the upper edge section 23. The opening and closing device rainwater receiver 73 has a U-shaped cross section with the upper side being the receiving port 81, and the hanging piece 75 of the drain 71 is disposed in the receiving port 81. In other words, the water droplets W that flow downward between the storage section 31 and the exterior material 57, between the exterior material 57 and the exterior wall material 19, and between the exterior wall material 19 and the structural body 51 are once received by the upper surface of the drain 71, and then fall from the hanging piece 75 provided on the drain 71.

The water droplets W fall into the receiving port 81 of the opening/closing device rainwater receiver 73. The water droplets W that fall from the hanging piece 75 are received by the receiving port 81 and flow along the opening/closing device rainwater receiver 73 to one end 95 in the longitudinal direction of the opening/closing device rainwater receiver 73. The end 95 of the opening/closing device rainwater receiver 73 is inserted into one of a pair of outer frames 41 that are arranged on the left and right sides of the opening 13. The outer frame 41 has a hollow portion 93. Therefore, the water droplets W that fall from the end 95 of the opening/closing device rainwater receiver 73 flow through the hollow portion 93 to the lower end of the outer frame 41, and are finally drained from the outer frame 41 to the outside of the surface of the exterior material 57.

In this way, the water droplets W received by the drain 71 are received by the opening/closing device rainwater receiver 73, which is longer than the upper edge 23 of the sash frame 21, and are discharged from its end 95 to the outside by the outer frame 41. In other words, rainwater will not flow between the closed shutter curtain 15 and the sash window 29 attached to the sash frame 21 between the pair of left and right vertical edges 25 of the sash frame 21. As a result, the opening/closing device mounting structure can prevent rainwater from entering and adhering to the window glass surface, etc.

In addition, in this opening and closing device mounting structure, the cross-sectional shape of the opening and closing device rainwater receiver 73 is U-shaped in a direction perpendicular to the longitudinal direction. Therefore, the opening and closing device rainwater receiver 73 has an outer plate portion 83 on the outside with the receiving port 81 in between, and an inner plate portion 91 on the structural body 51 side. In this opening and closing device mounting structure, the outer plate portion 83 of the opening and closing device rainwater receiver 73 is fixed to the lower surface 37 of the storage section 31 located above. By fixing the opening and closing device rainwater receiver 73 to the lower surface 37 of the storage section 31, the receiving port 81 is positioned below the hanging piece 75 of the drip edge 71. Meanwhile, the inner plate portion 91 on the opposite side of the outer plate portion 83 with the receiving port 81 in between is positioned close to or in close contact with the upper edge portion 23 of the sash frame 21. This eliminates the need to drill holes in the sash frame 21 for fixing, and allows the water droplets W that fall from the hanging piece 75 of the drip tray 71 to be received in the receiving port 81, preventing rainwater from entering and adhering to the window glass surface. As a result, the opening and closing device rainwater receiver 73 can be fixed to the storage section 31 of the window shutter 11, eliminating the need for a fixing means to the building structural body 51. Also, there is no need to drill holes in the building.

In addition, in this opening/closing device mounting structure, the inner plate portion 91 of the opening/closing device rainwater receiver 73 may be configured to be fixed to the structural frame 51 side in close contact with the upper edge portion 23. Here, the structural frame 51 side refers to the upper edge portion 23 of the sash frame 21, or the frame itself. Also, the fixture frame refers to the sash frame 21 to which the sash window 29 is attached, i.e., the upper edge portion 23 and other fixtures. The cross-sectional shape of the opening/closing device rainwater receiver 73 is U-shaped in a direction perpendicular to the longitudinal direction.

As a result, in the mounting structure for the opening and closing device, the inner plate portion 91 of the opening and closing device rainwater receiver 73 is fixed to the structural body 51 side in close contact with the upper edge portion 23, so that the receiving port 81 is positioned below the hanging piece 75 of the drain 71 with no gap between the inner plate portion 91 and the upper edge portion 23.

Furthermore, in this mounting structure for the opening and closing device, a rainwater receiver 73 for the opening and closing device is disposed between the shutter curtain 15 unrolled from the storage section 31 and the upper edge section 23. The rainwater receiver 73 for the opening and closing device is longer than the upper edge section 23. The end 95 of the rainwater receiver 73 for the opening and closing device is disposed with a gap 99 between the pair of outer frames 41 disposed on the left and right sides of the opening 13. The rainwater receiver 73 for the opening and closing device has a U-shaped cross section with the receiving port 81 on the upper side, and the hanging piece 75 of the drain 71 is disposed in the receiving port 81. In other words, the water droplets W that flow downward between the storage section 31 and the exterior material 57, between the exterior material 57 and the exterior wall material 19, and between the exterior wall material 19 and the structural body 51 are once received by the upper surface of the drain 71 and then fall from the hanging piece 75 provided on the drain 71.

The water droplets W fall into the receiving port 81 of the opening/closing device rainwater receiver 73. The water droplets W that fall from the hanging piece 75 are received by the receiving port 81 and flow along the slope of the opening/closing device rainwater receiver 73 to one end 95 in the longitudinal direction of the opening/closing device rainwater receiver 73. The end 95 of the opening/closing device rainwater receiver 73 is disposed with a gap 99 between the pair of outer frames 41. Therefore, the water droplets W that fall from the end 95 of the opening/closing device rainwater receiver 73 flow mainly along the outer frame 41 to the lower end of the outer frame 41 between the vertical side portion 25 of the sash frame 21 and the outer frame 41, and are finally drained outside the surface of the exterior material 57.

In this way, the water droplets W received by the drain 71 are received by the opening and closing device rainwater receiver 73, which is longer than the upper edge 23 of the sash frame 21, and flow down from its end 95 along the outer frame 41 and discharged to the outside. In other words, rainwater will not flow between the closed shutter curtain 15 and the sash window 29 attached to the sash frame 21 between the pair of left and right vertical edge portions 25 of the sash frame 21. As a result, rainwater can be made to flow down along the outer frame 41 of the window shutter 11, which is positioned outside the sash frame 21, and therefore rainwater can be prevented from entering and adhering to the outer surface of the window glass, etc.

In the opening and closing device rainwater collector 73 according to this embodiment, the water droplets W that flow downward between the storage section 31 and the exterior material 57, between the exterior material 57 and the exterior wall material 19, and between the exterior wall material 19 and the structural body 51 are first received on the upper surface of the drain 71, and then fall from the hanging pieces 75 provided on the drain 71.

The water droplets W fall onto the receiving port 81 of the opening/closing device rainwater receiver 73. The water droplets W that fall from the hanging piece 75 are received by the receiving port 81 and flow along the opening/closing device rainwater receiver 73 to one end 95 in the longitudinal direction of the opening/closing device rainwater receiver 73. The end 95 of the opening/closing device rainwater receiver 73 may be inserted into one of a pair of outer frames 41 arranged on the left and right sides of the opening 13. Therefore, the water droplets W that fall from the end 95 of the opening/closing device rainwater receiver 73 flow through the hollow portion 93 to the lower end of the outer frame 41, or flow down along the outer frame 41, and are finally drained from the outer frame 41 to the outside of the surface of the exterior material 57. As a result, the adhesion of rainwater to the outer surface of the window glass due to the intrusion of rainwater can be suppressed.

In this way, the water droplets W received by the drain 71 are received by the opening/closing device rainwater receiver 73, which is longer than the upper edge 23 of the sash frame 21, and are discharged to the outside from its end 95 by the outer frame 41. In other words, rainwater will not flow between the closed opening/closing body and the sash window 29 attached to the sash frame 21 between the pair of left and right vertical edge portions 25 of the sash frame 21.

Therefore, with the opening and closing device mounting structure and the opening and closing device rainwater receiver 73 according to this embodiment, it is possible to prevent rainwater from entering and adhering to the outer surface of the window glass, etc., when the shutter curtain 15 is closed.
