Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sash watertight device capable of sufficiently and surely discharging rainwater that has entered the indoor side of an inner rail for guiding an inner shoji, and significantly improving watertightness.

[0002]

2. Description of the Related Art Conventionally, as a heat insulating sash, there is a heat insulating sash in which a frame and a shoji are compositely assembled through a heat insulating material to reduce heat transfer from the outside to the inside. For example, in the lower frame, the lower frame is composed of two members, an outer member and an inner member made of aluminum, and these outer member and the inner member are connected via a heat insulating bridge made of synthetic resin. . The heat insulating bridge prevents heat transfer from the outer member to the inner member, prevents the inner member from being cooled, and makes the heat transmission coefficient of the heat insulating sash extremely small. Of course, the upper frame, the vertical frame, the shoji screen, and the like have the same configuration.

[0003]

Even in the lower frame of such a heat insulating sash, various watertight devices are adopted so that rainwater, particularly rainwater does not enter the inside of the lower frame during a typhoon. . For example, by soaking the lower part of the lower rail of the outer shoji and the inner shoji, rainwater is collected on the dish plate part between the outer rail and the inner rail of the lower frame and the inner plate dish part of the inner rail, The pressure is kept equilibrium with the pressure on the indoor side to maintain water tightness.

When the rainwater is discharged, on the indoor side of the shoji screen, the rainwater is discharged from the plate portion between the outer rail and the inner rail through the notch at the end of the outer rail, and the inner rail. Is discharged from the inner side plate portion through the notch through the end of the inner rail to the plate portion between the outer rail and the inner rail. On the indoor side of the shoji screen, the end plate of the inner rail is guided from the inner plate part of the inner rail through the notch to the plate part between the outer rail and the inner rail for discharge.

However, in this structure, when there is a large amount of rainwater, such as during a typhoon, on the indoor side of the inner rail, the rainwater enters the room beyond the rising wall of the lower frame that forms the boundary with the room. There is a possibility that it may occur, and it cannot be said that the structure is necessarily watertight.

In the watertight device disclosed in Japanese Utility Model Laid-Open No. 60-99691, a drain groove is formed between the outer rail and the inner rail of the lower frame, and a lid body having a drain hole is provided in the drain groove. Installed. However, even this watertight device did not sufficiently consider the discharge of rainwater on the indoor side of the inner rail.

The object of the present invention was made in view of such circumstances, and by keeping contact between the sealing material and the rising wall of the cover material, the internal shoji can be maintained while maintaining airtightness and heat insulation. It is an object of the present invention to provide a sash watertight device that can sufficiently and surely discharge rainwater that has entered the indoor side of an inner rail to be guided and that has a significantly improved watertightness.

[0008]

In order to achieve this object, the present invention provides an upper frame, a lower frame, and left and right vertical bars for a window frame framed by an upper frame, a lower frame, and left and right vertical frames. The lower frame forming the window frame in the sash window, which is a frame and is configured to slidably move the sliding doors inside and outside, is formed in a step-like manner so that the window frame is gradually increased from the outside to the inside, In a watertight device of a sash in which an outer rail and an inner rail for guiding the inner shoji are provided on the lower frame, and a dish plate portion is formed from the lower portion of the outer rail toward the indoor side, at least when the shoji is closed. A hollow portion having a rising wall is formed between the outer rail and the inner rail outside the inner rail in which the rainwater inside the inner rail is guided into the hollow portion under or near the inner rail. An opening is formed, and the hollow part rises. The opening for guiding the rainwater in the hollow portion to the outside is formed, the opening of the rising wall, is characterized in that drain valve is only possible emission to rainwater outside.

[0009]

With the above construction, the present invention
On the indoor side of the shoji screen when the shoji screen is closed, rainwater that has infiltrated the indoor side of the inner rail will be discharged through the notch at the end of the inner rail and the plate part between the outer rail and the inner rail. Is stored in the chamber while the pressure is balanced between the indoor side and the outdoor side, and is discharged through the notches in the outer rail.

Moreover, in addition to this, when the shoji is closed, on the indoor side of the inner shoji, the rainwater that has entered the inner side of the inner rail is guided into the hollow portion through the opening below the inner rail. Then, it is discharged from the inside of the hollow portion to the outside through the opening of the rising wall and the drain valve. Therefore, the rainwater that has entered the indoor side of the inner rail can be sufficiently and reliably discharged, and the watertightness can be significantly improved without impairing the airtightness / heat insulating performance.

The hollow portion may be formed separately from the lower frame or may be formed integrally with the lower frame.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A watertight device for a sash according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a view of an adiabatic sash provided with a watertight device for a sash according to an embodiment of the present invention, as viewed from the indoor side. In this figure, the opening frame 10 includes an upper frame 11 and a lower frame 1.
2, a left vertical frame 13 and a right vertical frame 14 are four-sidedly assembled, and an outer shoji 15 and an inner shoji 16 are stored in the opening frame 10 in a sliding manner. The outer shoji 15 and the inner shoji 16 include an upper rail 17, 18, a lower rail 19, 20, a middle rail 21, 22, a left vertical frame 23, a combination inner frame 24, and an unillustrated combination outer frame, respectively.

FIG. 2 is a sectional view taken along the line [B]-[B] in FIG. In the figure, the lower frame 12 is the lower frame outer member 1
2a and the lower frame inner member 12b, and synthetic resin heat insulating bridges 33, 33 are interposed between them. Further, the outer rails 3 for guiding the door roller 42 are respectively provided on the upper portions of the outer member 12a and the inner member 12b of the lower frame.
4 and the inner rail 35 are formed.

The lower crosspieces 19 and 20 of the external shoji and the internal shoji consist of outer members 19a and 20a and inner members 19b and 20b. Outer members 19a, 20a and inner member 19 of the lower rail
Insulation bridge 3 made of synthetic resin is provided between b and 20b.
9,39 are interposed. Further, the heat insulating bridge 39 at the lowest position is provided with notches 39a at predetermined intervals. Pair glasses (registered trademark) 40, 40 are attached to the upper portions of the lower crosspieces 19, 20 via gaskets 41, 41.

The upper surface of the outer frame 43 of the door roller 42 is in contact with the second insulating bridge 39 from the bottom, and is locked by a known means (not shown). Further, the lower end of the outer frame 43 is placed and supported on the cutout heat insulating bridge 39 at the lowest position. As a result, the vertical displacement of the door roller 42 is eliminated, and
There is no misalignment in the finding direction. Also, the door car 42
The lower side portions of the inner frame 44 are positioned and pressed between the cutouts 39a of the lowermost heat insulating bridge 39. As a result, blurring of the door roller 42 in the prospective direction is suppressed.

Further, in this embodiment, the inner member 12 of the lower frame is used.
A lower frame cover material 45 (hollow portion) made of synthetic resin is provided to cover the externally exposed portion of b and the heat insulating bridge 33. The lower frame cover material 45 is a hanging portion 4 that hangs along a vertical piece 46 of the lower frame outer member 12 a that supports the heat insulating bridge 33.
It has 7 (standing wall). An engaging portion 49 that engages with the engaging portion 48 of the vertical piece 46 is formed at the lower end of the hanging portion 47. Further, the hanging portion 47 has a rib mounted on the upper portion of the vertical piece 46. 50 are formed. A seal member 51 provided at the lower end of the inner member 19b of the lower rail of the outer shoji is in contact with the outer surface of the hanging portion 47 as a seal seat portion. Thereby, like the upper frame, the seal seat portion can be provided in a place where the mating member of the seal material 51 is difficult to be provided,
The double seal is realized in cooperation with the sealing material 52 at the lower end of the outer member 19a of the lower rail of the shoji screen.

The lower frame cover member 45 further includes a horizontal portion 53 extending horizontally from the hanging portion 47 and the inner member 1 of the lower frame.
It has a vertical portion 55 that extends vertically along the rail 35 and the hanging piece 54 of 2b. At the lower end of the vertical portion 55, the engaging portion 5 that engages with the engaging portion 56 below the hanging piece 54.
7 are formed. A rib 58 that abuts the vertical piece 54 at the same height as the horizontal portion 53 is formed in the middle portion of the vertical portion 55, and the upper end of the vertical portion 55 is engaged with the engaging portion 59 of the rail 35. The engaging portion 60 is formed. The engaging portion 57, the rib 58, and the engaging portion 60 are in non-surface contact, for example, in line contact with the rail 35 and the hanging piece 54. Therefore, even if the lower frame cover material 45 is exposed to the outside air and is cooled, the cold heat is significantly less likely to be transferred from the lower frame cover material 45 to the inner member 12b of the lower frame through this line contact portion, and the heat insulation Performance is improved.

Further, the seal member 61 provided at the lower end of the outer member 20a of the lower rail of the inner shoji is in contact with the vertical portion 55 of the lower frame cover member 45 as a seal seat portion. Therefore, the double seal is realized in cooperation with the sealing material 62 at the lower end of the inner member 20b of the lower rail. Further, since the lower frame cover member 45 covers the externally exposed portion of the inner member 12b of the lower frame, it naturally serves to insulate the inner member 12b and also covers the heat insulating bridge 33. , The design is also improved.

Next, FIG. 3 is a sectional view of the lower frame in which the inner shoji is positioned when the shoji is closed, and is a view for showing the watertight device. In the watertight device according to the present embodiment, the lower end of the inner rail 35 is formed with a first opening 71 for guiding the rainwater stored inside the inner rail 35 into the lower frame cover member 45. The first opening 71 is provided on the plate portion 7 of the lower frame member 12b.
It may be formed closer to the second inner rail 35.

In the lower frame cover material 45, the rib 58 is cut out, and the lower side of the vertical portion 55 of the cover material 45 is cut out to form a second opening 73. Further, the lower portion of the hanging portion 47 (upstanding wall) of the cover material 45 is cut out to form the third opening 74, and the rib 50 of this is formed.
Is cut out. A drain valve (check valve) 75 that can only discharge the rainwater to the outside is provided outside the third opening 74. Further, the lower frame outer member 12a is formed with a dish plate portion 76 that extends from the lower portion of the outer rail 34 toward the indoor side and stores rainwater, and below the outer rail 34, a fourth opening 77 is formed. Are formed.

Such first to fourth openings 71, 73,
The watertight device consisting of 74 and 77 is provided in the lower frame portion where the inner shoji is located when the shoji is closed, and the watertight device in the lower frame portion where the outer shoji is located when the shoji is closed is constructed in the same manner as the conventional one. ing.

Next, the arrangement of the first to fourth openings 71, 73, 74, 77 in the finding direction will be described with reference to FIGS. 4 and 5. FIG. 4 is a plan view of a portion of the lower frame in which the inner sliding door is located when the sliding door is closed, and FIG. 5 is a partially cutaway perspective view of the lower frame according to the watertight device of this embodiment. As shown in FIG. 4, two sets of the first openings 71 are provided for each pair. Two sets of the second openings 73 are provided, one for each of the first openings 71.
Is displaced in the finding direction. Third opening 7
Two sets of four are provided one by one, and are displaced in the finding direction with respect to the second opening 73, but are located at substantially the same position in the finding direction with respect to the first opening. These first to third openings 71, 73, 74 are the second openings 7
If 3 is displaced in the direction of finding with respect to the others, as will be described later, it is possible to prevent rainwater from invading into the room due to reverse flow of the drain valve 75, and the number and displacement distance are design matters. . Further, the fourth opening 77 is for simply draining rainwater from the plate portion 76.

As shown in FIG. 5, on the indoor side of the inner shoji when the shoji is closed, the rainwater that has infiltrated the inner side of the inner rail 35 passes through the first opening 71 of the inner rail 35 to the lower frame. It is guided into the cover material 45. The rainwater that has entered the cover material 45 flows in the finding direction as shown by the arrow in FIG. 5, and is guided further downward through the second opening 73 of the vertical portion 55 of the cover material. After that, the rainwater is further flowed in the finding direction, is guided to the drain valve 75 (FIG. 3) through the third opening 74 of the hanging portion 47 of the cover material, and is drained through the drain valve 75 which is the check valve. It is discharged to the plate portion 76. Plate part 7
From the sixth, the fourth opening 77 of the outer rail 34 or the outer rail 3
4 is discharged to the outside through the notch 34a (FIG. 4) at the end of the No. 4 end.

On the other hand, when the shoji screen is closed, on the indoor side of the shoji screen, the rainwater that has entered the indoor side of the inner rail 35 passes through a notch (not shown) at the end of the inner rail 35. It flows into the dish plate portion 76 between the outer rail 34 and the inner rail 35, and is stored while balancing the pressure between the indoor side and the outdoor side, and through a notch or the like (not shown) in the outer rail 34. Is discharged.

As described above, since the rainwater that has entered the inner side of the inner rail 35 can be sufficiently and reliably discharged, the watertightness can be remarkably improved.

Furthermore, since the second opening 73 is displaced from the other in the find direction, even if rainwater may flow back through the drain valve 75 (FIG. 3), which is a check valve, the rainwater may flow backward. Only enters the inside of the cover material 45 through the third opening 74, and there is no possibility of flowing into the room through the second opening 73 and the first opening 71.

The present invention is not limited to the above-mentioned embodiments, but can be variously modified.

[0029]
