JP-A-2005-139845

By the way, when the sash structure described in Patent Document 1 described above is used for a building sash or the like, an inner rail is provided with a drain hole for draining water that has fallen to the inside of the shoji. There is a problem in that water that has flowed in on the outdoor side frame body may be drawn into the room through the through hole of the inner rail due to a pressure difference between the outdoor side pressure and the indoor side pressure.
In addition, when an airtight line with an airtight material such as packing that seals the inner scabbard and the frame is formed between the inner scabbard and the indoor frame, as in a building sash, When water drawn into the indoor side adheres to an airtight material such as packing, there is a problem that the water is drawn into the indoor side due to a pressure difference inside and outside the airtight line.

  This invention is made in view of such a subject, Comprising: Provided the fitting which prevented that the water adhering to the outdoor side of a rail was drawn in by the indoor side by the pressure difference of indoor and outdoor With the goal.

A joinery according to the present invention is a joinery in which a shoji is placed in a frame, and a rail for guiding the shoji disposed in the lower frame of the frame and at least one of the rails supports the rail, It is characterized by comprising a plurality of walls arranged in the prospective direction and a plurality of drain holes formed in each of the plurality of walls.
According to the present invention, since the water drainage holes are respectively provided in the plurality of wall bodies supporting the rail, water such as rainwater adhering to the outdoor side of the rail of the lower frame is stored by the pressure difference between the outdoor side and the indoor side. Even if it flows inward, it can suppress flowing into the indoor side through the plurality of drain holes due to the flow resistance due to the distance in the prospective direction between the plurality of drain holes.

Moreover, it is preferable that the positions of the plurality of drain holes are shifted in at least one of the longitudinal direction and the height direction of the plurality of wall bodies.
When the plurality of drain holes are shifted in the longitudinal direction, the flow distance of the water flowing into the indoor side due to the difference in atmospheric pressure becomes longer, so that it can be further prevented from flowing into the indoor side. Further, when the plurality of drain holes are displaced in the height direction, it is possible to prevent water from flowing into the indoor side due to the height difference.

Moreover, it is preferable that the plurality of drain holes are formed at any positions that do not overlap with each other in the longitudinal direction of the wall body.
In this case, since the water flowing into the indoor side due to the pressure difference meanders for a longer distance, the intrusion route becomes a maze and difficult to enter the indoor side, so that the water tightness is enhanced.

Moreover, the cover part may be formed in the upper part of a some wall body, and the said rail may be formed in this cover part.
In this case, the rail for guiding the shoji can be supported with high strength by the lid portion and the plurality of wall bodies.

  According to the composite fitting according to the present invention, since the water drainage holes are respectively provided in the plurality of wall bodies supporting the rail, the water adhering to the lower frame on the outdoor side of the rail is stored by the pressure difference between the outdoor side and the indoor side. Even if it flows inward, it is possible to suppress the flow into the indoor side through the plurality of drainage holes due to the resistance in the prospective direction between the plurality of drainage holes.

The upper metal rod 10a, the lower metal rod 11a, and the vertical metal rod 12a are made of an aluminum alloy or the like. Further, in the external shoji 8, the upper rod 10, the lower rod 11, and the left and right vertical rods 12 have the same configuration. The description will be omitted using the reference numeral. Note that the left and right downspouts 12 have a front end spider and a summoning downspout.
A door wheel 17 to be placed on the inner rail 16 is installed at the lower part of the metal lower arm 11a of the inner shoji 7, and a door wheel 14 to be placed on the outer rail 15 is also installed at the lower portion of the metal armor 11a of the outer shoji 8. ing.

1 to 3, the multi-layer glass 9 that is supported by the inner and outer children 7 and 8 has spacers 21 at the ends of the four sides between the two glass panels 20. Intervene. The side edges of the four sides of the multilayer glass 9 are continuously surrounded by a glazing channel 22 having a substantially U-shaped cross section over the entire circumference.
In the inner shoji 7 and the outer shoji 8, the glazing channel 22 is supported on the side edges of the four sides by the glass receiving portions 26 provided on the upper metal rod 10a, the lower metal rod 11a, and the left and right metal vertical rods 12a. The indoor side is covered with a resin upper rod 10b, a resin lower rod 11b, and left and right resin vertical rods 12b, respectively.

In FIG. 3, each glazing channel 22 is formed of a base portion 22a that abuts against the end surface of the multilayer glass 9, and rising portions 22b that respectively abut on both side edges, and both rising portions 22b are connected to the fin portions 23 on the base portion 22a side. The flat part and the tip fin part 25 of the tip part are formed, and the other end part of the tip fin part 25 forms a protrusion 25a that protrudes on the opposite side of the flat part.
Then, in the metal lower arm 11 a of the lower arm 11, both the indoor and outdoor rising portions 22 b are pressed by both side portions 26 a of a panel receiving portion 26 having a substantially U-shaped cross section provided so as to surround the glazing channel 22. As a result, the fins 23 and the tip fins 25 of the two rising portions 22b of the glazing channel 22 press both sides of the multi-layer glass 9 indoors and outdoors to seal hermetically between the glazing channel 22 and both sides 26a. doing. Moreover, the resin lower collar 11b connected to the indoor side has the front projection 28 fitted between the tip of the side portion 26a of the panel receiving portion 26 and the projection 25a of the tip fin portion 25 to press the rising portion 22b. doing.

Such a configuration of the inner shoji 7 and the outer shoji 8 is the same not only in the lower collar 11 but also in the upper collar 10 and the left and right vertical collars 12.
As a result, the multi-layer glass 9 of the inner shingles 7 and the outer shingles 8 and the rising portions 22 b of the glazing channels 22 are hermetically sealed by the side portions 26 a on the indoor side of the panel receiving portions 26.
Moreover, in the inner shoji 7, the door pulley holding part 27 which hold | maintains the door wheel 17 is connected to the lower side of the panel receiving part 26 in the metal lower arm 11a. In the external shoji 8, a door pulley holding portion 30 that holds the door roller 14 is connected to the lower side of the support frame 29 that is further below the panel receiving portion 26 in the metal lower arm 11 a.

Next, the rail structure in the metal lower frame 3a will be described with reference to FIGS.
In FIG. 3, a rail punch 32 having a substantially U-shaped cross section for fixing the door pulley holding portion 27 to the lower side of the panel receiving portion 26 is formed on the metal lower rod 11 a of the lower rod 11 of the inner shroud 7. A portion of the door wheel 17 protrudes from the door wheel holding portion 27 in the downward recess of the rail prick 32.
An upper flat portion 33 as an upper portion provided with the inner rail 16 and a lower step portion 34 provided with the outer rail 15 are connected to the metal lower frame 3a facing the door wheel 17 held by the metal lower rod 11a. Is formed.

In the upper flat portion 33 of the metal lower frame 3a shown in FIGS. 3 and 4, a plurality of strips supporting the inner rail 16, for example, two strips, an inner wall plate 35 and an outer wall plate 36 are located at a position facing the door wheel 17. It is installed at a predetermined interval in the inside and outside direction (forecast direction). The inner wall plate 35 on the indoor side has a substantially T-shape in cross-sectional view, and an inner hole portion 35a for draining is formed at an arbitrary position in the longitudinal direction. The inner hole portion 35a has, for example, a rectangular shape opened upward.
Further, the outer side outer wall plate 36 has a substantially stepped shape bent in a sectional view, and an outer hole portion 36a for draining is formed at an arbitrary position in the longitudinal direction. The outer hole portion 36a also has, for example, a rectangular shape opened upward. In addition, the shape of the inner hole part 35a and the outer hole part 36a is not restricted to a rectangle, and arbitrary shapes can be adopted.

  Then, in the two inner wall plates 35 and the outer wall plates 36 that are spaced apart in the prospective direction, as shown in FIGS. 4 and 5B, the inner hole portion 35a and the outer hole portion 36a are in the longitudinal direction (finding direction). Are also completely misaligned. In the example shown in FIG. 4, the inner hole portion 35a and the outer hole portion 36a are separated by 10 mm. As a result, when water such as rainwater adheres to the outdoor side of the outer wall plate 36 on the upper flat surface portion 33, the inner hole portion 35a of the inner and outer wall plates 35, 36 can be drawn even if it is drawn into the indoor side due to an atmospheric pressure difference inside and outside. Since the outer hole portion 36a is displaced, the intrusion path becomes a labyrinth and becomes a long distance, so that water can be prevented from entering.

  The inner hole portion 35a of the inner wall plate 35 and the outer hole portion 36a of the outer wall plate 36 do not have to be completely displaced in the longitudinal direction, for example, may be partially overlapped or may be completely overlapped. Further, they may be formed at the same position in the longitudinal direction. Even in these cases, the inner hole portion 35a and the outer hole portion 36a are set at a predetermined distance in the prospective direction, and therefore flow resistance is generated in the water drawing direction, so that the inner hole portion 35a and the outer hole portion 36a are hardly drawn into the indoor side.

As shown in FIG. 5A, the inner rail 16 connected to the upper portions of the inner wall plate 35 and the outer wall plate 36 includes a rail receiving portion 37 for seating the door wheel 17 and two long and short leg portions 38a and 38b. ing. The rail receiving portion 37 is formed by biasing a convex curved portion 37a on which the door wheel 17 is seated to one side in the prospective direction, and has a lid portion 37b for supporting both sides of the convex curved portion 37a at a lower portion thereof.
Moreover, the long leg part 38a and the short leg part 38b which are extended under the cover part 37b differ in the length. In a state where the lid portion 37b of the inner rail 16 is seated on the outer wall plate 36 and the inner wall plate 35, the long leg portion 38a has a convex portion that engages with the bent concave portion of the outer wall plate 36 at the lower end and abuts the upper flat portion 33. The short leg portion 38b has a bent shape that engages with a T-shaped head formed on the upper end portion of the inner wall plate 35.

Then, by fitting the long and short leg portions 38a, 38b of the inner rail 16 to the outer wall plate 36 and the inner wall plate 35, the inner rail portion 16 can be integrated as shown in FIG. Further, as shown in FIG. 4, even if the outer wall plate 36 has an opening 36b that overlaps the inner hole portion 35a separately from the outer hole portion 36a, the long leg portion 38a can be engaged by engaging the inner rail 16. The opening 36b can be closed. The long leg portion 38a is not formed at the position of the outer hole portion 36a. Note that the opening 36 b may not be formed in the outer wall plate 36.
Further, as shown in FIG. 3, an outer fin portion 40 made of an elastic material such as rubber is formed as a sealing member at the end portion on the outdoor side of the upper flat portion 33 of the metal lower frame 3 a so as to protrude in a convex curved shape. In this state, the outer fin portion 40 abuts against the metal lower collar 11a of the lower collar 11 in a state where the outer cover 8 is held at the closed position on the frame 5, and the airtight state can be maintained.

Further, a packing 41 such as a packing provided at the outdoor side end of the resin lower frame 3b of the lower frame 3 can be brought into contact with the metal lower collar 11a of the inner shoji 7 in the closed position, and can be kept airtight. In addition, the structure which seals between the metal lower frame 3a and the metal lower collar 11a of the inner impeller 7 with the packing 41 is not only the lower frame 3 and the lower collar 11, but also the upper frame 2 and the upper collar 10, It is also installed between the frame 4 and the vertical fence 12. These airtight mechanism portions constitute an airtight line.
Next, the outer rail 15 is formed in the corner | angular part of the outdoor side at the lower step part 34 of the metal lower frame 3a. In the present embodiment, the outer rail 15 is installed below the inner rail 16, but the double-glazed glass 9 is formed at the same height by the inner shingles 7 and the outer shingles 8.
In the upper flat portion 33, the indoor side space of the inner rail 16 is referred to as K1, and the outdoor side space is referred to as K2.

The sliding window 1 according to the present embodiment has the above-described configuration, and the operation will be described next.
In the sliding window 1 shown in FIG. 1 and FIG. 3, rainwater or the like, for example, from a small gap between the rising part 22 b on the outdoor side of the glazing channel 22 of the inner fold 7 and the double glazing 9, etc. It is assumed that the inside of the inner rail 16 has fallen into the space K1 on the upper flat portion 33 of the metal lower frame 3a. In this case, the water that has fallen into the upper flat portion 33 of the space K1 flows out of the inner hole portion 35a of the inner wall plate 35 that supports the inner rail 16, flows along the longitudinal direction of the outer wall plate 36, and passes through the outer hole portion 36a. Flows outward. And it falls to the lower step part 34 and is discharged | emitted outside through the discharge port which is not shown in figure.

  In addition, in the sliding window 1 according to the first embodiment, when water such as rainwater falls and accumulates in the space K2 on the upper flat portion 33 of the metal lower frame 3a on the outdoor side of the inner rail 16, the outdoor side and It is easy to pull in to the indoor side of the inner rail 16 due to the pressure difference on the indoor side. In this case, water can flow from the upper flat portion 33 of the space K2 through the outer hole portion 36a of the outer wall plate 36 into the inner hole portion 35a of the inner wall plate 35 on the indoor side. Since the distance from the outer hole 36a to the inner hole 35a flows, it is difficult to reach the inner hole 35a by resistance.

In particular, in this embodiment, since the outer hole portion 36a of the outer wall plate 36 and the inner hole portion 35a of the inner wall plate 35 that constitute the drainage path are disposed so as not to overlap in the longitudinal direction, the drainage path for drawing in rainwater. Becomes a meandering maze, making it difficult for water to enter the indoor space K1. Therefore, the water tightness of the drainage path by the outer hole part 36a and the inner hole part 35a becomes high.
Therefore, the drawn water accumulates in the upper flat surface portion 33 of the space K1 on the indoor side of the inner rail 16 and adheres to the packing 41 constituting the airtight line or condenses, so that the pressure difference between the indoor and the outside causes It can prevent being pulled in.

As described above, according to the sliding window 1 according to the present embodiment, the parallel inner wall plate 35 supporting the inner rail 16 on the lower frame 3 and the inner hole portion 35a and the outer hole portion 36a of the outer wall plate 36 are displaced. Since the maze-like drainage path is formed, even if rainwater or the like accumulates in the outdoor-side space K2, there is an advantage that water does not easily enter from the outdoor side to the indoor side due to a difference in atmospheric pressure inside and outside, and water tightness is high.
Further, even if an airtight line by the packing 41 etc. is installed on the indoor side of the inner rail 16, it is difficult for water to enter from the outdoor side to the indoor side on the lower frame 3. It is possible to prevent water or the like from adhering to the inside and pulling water droplets or condensed water into the room due to a pressure difference between the inside and outside.

In addition, the fitting by this invention is not limited to the sliding window 1 by 1st embodiment mentioned above, A suitable change, replacement, etc. are possible in the range which does not deviate from the summary of this invention.
Although other embodiments and modifications of the present invention will be described below, the same or similar parts as those described in the above-described embodiments will be described using the same reference numerals.

Next, the lower frame 3 of the sliding window 1A according to the second embodiment of the present invention will be described with reference to FIG.
In the lower frame 3 of the frame 5 of the sliding window 1A shown in FIG. 6, the metal lower frame 3a that supports the inner rail 16 has a stepped upper step 44 instead of the upper flat portion 33 of the first embodiment described above. The lower step 34 is formed in the same manner as in the first embodiment. The upper step portion 44 of the metal lower frame 3a is stepped with a first plane portion 44a at a relatively high position and a second plane portion 44c at a relatively low position via the step portion 44b.
An inner wall plate 35 is formed at an appropriate position on the first flat surface portion 44a, for example, at a corner portion having the step portion 44b of the first flat surface portion 44a. Moreover, the outer wall board 36 is formed on the 2nd plane part 44c.

In FIG. 7, an inner hole portion 35a is formed in the inner wall plate 35 provided in the first flat surface portion 44a, and an outer hole portion 36a is formed in the outer wall plate 36 provided in the second flat surface portion 44c. The inner wall plate 35 is formed at a position higher than the outer wall plate 36. The inner hole portion 35a and the outer hole portion 36a are overlapped in the longitudinal direction, but are displaced in the height direction. As shown in FIGS. 6 and 7, the upper inner hole portion 35a and the lower hole portion 36a The outer hole part 36a is installed so that a part of the up-down direction may overlap.
Or you may set the step part 44b which is the height difference of the 1st plane part 44a and the 2nd plane part 44c larger so that the inner hole part 35a and the outer hole part 36a may not overlap with an up-down direction. Further, the positions of the inner hole portion 35a and the outer hole portion 36a may be shifted in the longitudinal direction. The remaining structure of the sliding window 1A is the same as that of the sliding window 1 according to the first embodiment.

  Since the sliding window 1A according to the second embodiment has the above-described configuration, rainwater or the like can enter the indoor side of the inner rail 16 of the lower lid 11 from, for example, a small gap on the outdoor side of the glazing channel 22 of the inner shoji 7. Suppose that it fell on the 1st plane part 44a in the space K1 of the metal lower frame 3a. In this case, the water accumulated in the first flat surface portion 44a of the space K1 flows through the inner hole portion 35a of the inner wall plate 35 that supports the inner rail 16, falls down the step portion 44b, and is provided on the lower second flat surface portion 44c. The outer wall 36 flows out of the outer hole 36a. And water falls to the lower stage part 34 and is discharged | emitted outdoors.

In addition, in the sliding window 1A according to the second embodiment, when water such as rainwater falls and accumulates on the second flat surface portion 44c of the space K2 on the outdoor side of the inner rail 16, the atmospheric pressure on the outdoor side and the indoor side It is easy to draw water into the indoor side by the difference. However, since the step portion 44 b is formed between the outer wall plate 36 and the inner wall plate 35, water cannot get over the step portion 44 b and cannot reach the inner hole portion 35 a of the inner wall plate 35.
Therefore, the water accumulated on the second flat surface portion 44c can pass through the outer hole portion 36a, but cannot flow into the inner hole portion 35a on the stepped portion 44b, so that the outer hole portion 36a and the inner hole portion 35a The water tightness of the drainage channel is even higher and reliable.

FIG. 8 shows an inner rail which is a modification of the inner rail 16 and the inner wall plate 35 and outer wall plate 36 which support the inner rail 16 in the present invention.
