Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door and a bathroom in which water flowing from a bathroom is blocked at a fully-closed position of a shoji to prevent or prevent water from flowing out to a dressing room.

[0002]

2. Description of the Related Art Generally, an opening communicating with a bathroom and a dressing room is provided with a four-sided frame composed of an upper frame, a lower frame, and right and left vertical frames, and a door can be opened and closed in the four-sided frame. Is provided. Some bathrooms have sliding doors at their entrances (openings). In a bathroom configured in this manner, when a large amount of hot water overflows from the bathtub, or when a large amount of hot water is used in the washing area, the water cannot be completely drained from the drainage section of the washing area, and the water is not discharged from the bathroom side. There is a risk of getting over the lower frame of the opening to the dressing room side and getting wet on the floor of the dressing room. In particular, in a barrier-free bathroom where there is no step between the floor of the washing room, the upper surface of the lower frame, and the floor of the dressing room, or where there is no small step, water easily flows from the bathroom to the dressing room.

[0003] In order to solve this problem, there is a type in which a drainage groove is provided on the side of the washing area near the opening, but the drainage groove is formed so large that cleaning is troublesome. The grating was large and the handling was difficult. For this reason, there has been proposed a structure in which a drainage groove is provided in a lower frame of an opening to make the opening compact and improve the cleaning property (for example, see Japanese Patent Application Laid-Open No. 10-205237).

[0004]

However, in the above-mentioned bathroom, since the drainage ditch is formed compactly, when a large amount of water flows from the bathroom side, the drainage can not be completely drained and flows to the dressing room side. There was a fear of doing. In order to solve this problem, for example, in a sliding door, it is preferable that the sliding door shoji is configured so as to be able to sufficiently block or block water flowing from the bathroom side at the fully closed position, In a conventional sliding door or a bathroom provided with a sliding door, for example, only a fin-shaped water blocking member is provided between a lower portion of a sliding door shoji and a lower frame, and the water stopping performance is insufficient.

The present invention has been made in view of the above circumstances, and can sufficiently block water flowing from the bathroom side at the fully-closed position of the shoji, thereby suppressing the outflow of water to the undressing room side. It is an object to provide a sliding door and a bathroom that can be prevented or prevented.

The present invention is characterized by the sliding door 50 provided in the opening 12 or the bathroom 1 provided with the sliding door 50. The lower frame 13b has a drainage function of collecting and draining water flowing from the bathroom 1 side. That is,
The lower frame 13b is formed in a groove shape or a gutter shape whose upper part is opened so that the water collecting groove 19 itself is formed. Both ends of the water collecting groove 19 are closed by a vertical frame 13c joined to both ends of the lower frame 13b via a watertight material (caulking sealer).

The lower frame 13b has one side (bath side edge) engaged and supported by a lower frame receiving member 20 provided below the lower frame 13b, and the lower surface 13b of the floor surface 11a of the undressing room 11. The other side (undressing room side edge) is supported and fixed to the upper edge. At the bottom of the lower frame 13b, a horizontally elongated drain port 21 is provided, and a synthetic resin drain guide (funnel) 22 is formed.
Is installed. Below the lower frame 13b, there is provided a lower frame receiving material 20 having a water catching function of catching water leaking from around the lower frame 13b.

The lower frame receiving member 20 is made of, for example, an extruded aluminum alloy. The lower frame receiving member 20 is formed in a groove shape or a gutter shape having an open upper portion so as to form the water catching groove 23 itself. The lower frame receiving material 20 is shown in FIG.
As shown in FIG. 4, the width and the length are designed to accommodate the lower frame 13b including the left and right vertical frames 13c.
Both ends of the water catch groove 23 are closed by closing members 24a and 24b which are joined to both ends of the lower frame receiving member 20 in a watertight manner.
In the illustrated example, the edge of the lower frame 13b on the undressing room side extends to be fixed to the floor surface 11a of the undressing room 11,
Although it protrudes from the lower frame receiving material 20, the lower frame receiving material 20 may be formed with a large width that can also accommodate the edge of the lower frame 13b on the undressing room side.

The lower frame receiving member 20 is attached to the wash basin waterproof pan 4 on the bathroom side. A part of the washing room waterproof pan 4 on the undressing room side is cut away for mounting the lower frame receiving material 20, and one side (the bathroom side edge) of the lower frame receiving material 20 is provided on the cut surface 4 a thereof. They are abutted in a watertight manner via 25a, 25b and are joined by screws 26a, 26b as fixing tools. The closing members 2 provided at both ends of the lower frame receiving material 20

A hole 29 is provided. At the bottom of the lower frame receiving member 20, a horizontally elongated drain port 30 is provided, and a synthetic resin drain guide (funnel) 31 is attached. This lower frame receiving material 2
The drain port 30 of the lower frame 13b is formed with a larger diameter than the drain guide 22 of the lower frame 13b. The drain guide 22 of the lower frame 13b is inserted into the drain port 30 of the lower frame receiving member 20.

That is, the lower frame receiving material 20 catches water leaking from the periphery of the lower frame 13b and drains it from the drain port 30, and collects water in the lower frame 13b and drains it from the drain port 21. The water is also drained from the drain port 30 into the drain guide 31. One end of a drain pipe 32 is connected to a drain guide 31 attached to the bottom of the lower frame receiving member 20, and the other end of the drain pipe 32 is connected to, for example, the waterproof pan 7 below the bathtub 2. The water collected by the lower frame 13b and the water leaking from around the lower frame 13b are drained into the waterproof pan 7.

Lower frame 13b including the lower rail member 18
And the floor of the washing room 4 on the bathroom side and the floor 11a of the dressing room 11 are substantially flush, that is, there is no step, or even if there is a step, it is a small step, which is a so-called barrier-free type. . The lower rail member 18 has a plurality of (three in the illustrated example) guide grooves 17 formed on the upper surface of a substantially flat surface, and a groove 3 on the bathroom side adjacent to each guide groove 17.
3 are formed. The cross-sectional shape of the groove 33 may be a shape in which the width is narrowed downward, but a rectangular shape as shown in the illustrated example is preferable. The lower rail member 18 is made of, for example, an extruded aluminum alloy.

The lower rail member 1 is provided in the lower frame 13b.
Support members 34 made of synthetic resin for supporting the lower surface of 8 are provided at appropriate intervals in the longitudinal direction. The lower rail member 18 is provided with an engagement receiving portion 3 formed on one side of the lower frame 13b.
5, one side (bathroom side edge) is engaged and supported, and the other side (undressing room side edge) is formed on the rib 36 and the support member 34 formed on the other side in the lower frame 13b. By being fixed with the screw 37, it is detachably mounted in the lower frame 13b.

Each of the shoji screens 14A, 14B, and 14C has a glass panel or a resin panel 14g mounted inside a frame composed of an upper frame 14a, a lower frame 14b, and left and right vertical frames 14c. The upper frame 14a, the lower frame 14b, and the left and right vertical frames 14c are made of, for example, an extruded aluminum alloy. As shown in FIG. 5, in the fully closed state of the shoji screens 14A to 14C, the water flowing from the bathroom side is removed from the shoji screens 14A to 14C.
In order to prevent or shut out on the indoor surface side (bath surface side) of 14C, the lower frame 14b of each of the shoji 14A, 14B, 14C is provided with the respective shoji 14A, 14B, 14C of the lower rail member 18 of the lower frame 13b. 6 is provided with a hanging part 38 which is hung down in a groove 33 located on the bathroom side. The hanging part 38 is formed of a soft resin water stop member (over the entire length thereof) as shown in FIG. Lower frame water stop member.) 39 is provided.

The hanging portion 38 is integrally formed or integrally provided along the longitudinal direction on the indoor surface side of the lower frame 14b as shown in the illustrated example. It is preferable that a mounting groove 38a for mounting the member 39 is formed. The lower frame water stop member 39 has a fin 39a extending obliquely upward toward the bathroom side, and the fin 39a is slidably in contact with the inner wall of the groove 33 by its own elastic force. The fin 39a is formed upward, so that water flowing from the bathroom side is filled with the fin 39a.
Is pressed against the inner wall of the groove 33 (the inner wall on the bathroom side) by the weight or water pressure of the water accumulated on the upper side of the groove 33, so that the water stopping performance is further enhanced. Further, the lower frame water stopping member 39 has a ridge portion 3 for blindfolding above the fin 39a.
9b is preferably formed.

It is preferable that the lower frame water stopping member 39 is provided along the entire length of the sliding door in the width direction.
When the lower frame 14b is located between the left and right vertical frames 14c (that is, when the vertical frame has the vertical frame structure), the hanging portion 38 is not provided at the position of the vertical frame 14c. Therefore, the lower frame water stopping member 39 cannot be attached. Therefore, in order to stop the water between the vertical frame 14c and the lower frame 13b, the hanging portion 38 is provided at least below the vertical frame (including the door frame and the combination frame) 14c exposed on the bathroom side. In the same manner as described above, a water-stop member made of a synthetic resin (also referred to as a vertical-frame water-stop member) having the same water-stop function as the lower-frame water-stop member 39 as well as hanging in the groove 33.
40 are provided.

As shown in FIGS. 7 and 8, the vertical frame water stop member 40 is formed in a block shape with a cross section slidable in the groove 33 and a horizontal width of the vertical frame 14c. It is provided at the lower part. In this case, it is preferable that the vertical frame water stop member 40 is integrally formed or integrally provided with a synthetic resin vertical frame lower cap 41 mounted on the lower end of the vertical frame 14c. The vertical frame lower cap 41 is provided with a door roller unit 42 provided with the door roller 16 so as to be adjustable in height. The door unit 42
Is supported by the vertical frame 14c or the lower frame 14b,
It may be separate from the vertical frame lower cap 41.

When the height is adjusted by displacing the door roller 16 with respect to the vertical frame 14c, the vertical frame water stop member 40 moves up and down integrally with the vertical frame 14c. A gap S may be generated. In this case, water enters from the gap S at the end of the combination frame 14x exposed on the bathroom side, and wraps around to the undressing room side of the shoji screens 14A and 14B to flow out. is expected. Therefore, a protruding portion 43a made of synthetic resin protruding downward is provided at the end of the combination frame 14x exposed on the bathroom side as shown in FIGS. Preferably, at the end of the mating frame 14x exposed on the bathroom side, a mating frame end water stopping member 43 having a synthetic resin projecting portion 43a projecting downward and hanging in the groove 33 is provided. I have.

The protruding portion 43a is formed in a shape for closing the groove 33 at the fully closed position of the shoji. The joint frame end water stop member 43 including the protrusion 43a is
It is formed in a plate shape, and is attached to the end of the joining frame 14x so that the height can be adjusted so that the positional relationship between the protrusion 43a and the groove 33 can be adjusted with the height adjustment of the door roller 16. That is, the mating frame end portion water stop member 43 is attached to the end of the mating frame 14x with the screw 44, and the screw hole 45 through which the screw 44 is passed through the mating frame water stop member 43.
The height can be adjusted by making the long holes vertically long.

It is preferable that a fin 43n made of a soft resin is provided at the lower end of the protruding portion 43a so as to be in soft contact with the bottom of the groove 33. In addition, the end portion of the mating frame water stop member 43 covers the gap between the end of the mating frame 14x and the upper surface of the lower frame 14b (the upper surface of the lower rail member 18) to prevent water from entering. Fins 43m made of soft resin are provided. The fin 43m is preferably formed in an L-shape so as to be able to seal also between the adjacent shoji (medium shoji or outer shoji) on the undressing room side. In the groove 33 of the lower rail member 18, water that has broken through the water blocking members 39, 40, 43 in the region closer to the dressing room than the sliding doors 14 </ b> A to 14 </ b> C in the fully closed position is prevented from flowing out to the dressing room side. So below (in the lower frame)
A drain hole 45 for draining water is provided appropriately.

Next, the operation of the opening structure or the bathroom having the above configuration will be described. When entering the bathroom 1 to take a shower or take a bath,
A, 14B and 14C are closed to bring them into a fully closed state. Each shoji 1
4A, 14B, and 14C are provided with the lower frame water stop member 39, the vertical frame water stop member 40, and the combined frame end water stop member 43, so that water flowing from the bathroom side is stopped by these water stop members. It can be blocked by the members 39, 40, 43.

Since the lower frame water stop member 39 is provided on the hanging portion 38 which is suspended from the lower frame 14b of the sliding doors 14A, 14B and 14C into the groove 33 of the lower frame 13b, the lower member is simply lowered from the lower frame. Unlike the case where a soft resin water-stop member is hung on the frame, even if a large amount of water flows from the bathroom side vigorously, there is no turning over,
Since the fins 39a extend obliquely upward toward the bathroom, water flowing from the bathroom pools above the fins 39a, and the fins 3a are weighed by the weight or pressure of the water.
9a is closely attached to the inner wall of the groove 33 (the inner wall on the bathroom side), and can sufficiently prevent or block water flowing from the bathroom side. Since the fin 39a is provided in the hanging part 38 hung in the groove 33, unlike the case in which a soft resin water stopping member or fin is hung from the lower frame on the lower frame, the length of the fin is Can be shorter. In addition, when the water stop member is provided in the groove of the lower frame, it must be provided over the entire length of the groove, but since the water stop member is provided in the lower frame, it is only a length of one door body, and cost reduction is possible. I can do it.

In addition, a block-shaped vertical frame water retaining member which is suspended from the vertical frame and slidable in the groove is provided below the vertical frame of the shoji. The water flowing from the bathroom side can be sufficiently prevented or blocked by the lower frame water stopping member over the entire length of the sliding door in the lateral direction.
The fin 39a of the lower frame water stop member 39 is directed obliquely upward, so that the fin 39a is hardly turned up when the shojis 14A, 14B, and 14C are erected, and the lower portion of the lower frame 14b is suspended in the groove 33 of the lower frame 13b. 38 can be easily inserted.

[0034] In addition, the combination frame 14x exposed on the bathroom side.
Is provided with a protruding portion 43a which protrudes downward,
Since the protruding portion 43a is formed in a shape that closes the groove 33, water that flows from the bathroom side and enters the groove 33 in the region exposed to the bathroom side at the fully-closed position of the shoji is used for the shoji 14A and 14B. The flow into the lower groove 33 can be suppressed or prevented by the protruding portion 43a (the amount of flowing water can be reduced).
Outflow of water from the groove 33 below A, 14B to the undressing room side can be suppressed or prevented.

The projecting portion 43a is provided on a water stop member 43 at the end of the mating frame. The water stopping member 43 at the end of the mating frame is connected to the end of the mating frame 14x and the upper surface (lower portion) of the lower frame 14b. It is formed so as to close the gap with the upper surface of the rail member 18) and the gap with the adjacent sliding door (middle or outer sliding door) on the undressing room side with a fin 43m. Can be blocked. In addition, since the water stop member 43 at the end of the mating frame is provided so as to be adjustable in height, it can always be set at the best position regardless of the height adjustment of the door roller 16.

On the other hand, in the unlikely event that water is used,
9, 40, 43, the water is still present at the fully closed position of the groove 33 in the lower rail member 18.
Since the water is drained into the lower frame 13b from the drain hole 45 provided in the area on the undressing room side with respect to A, 14B and 14C, it is possible to prevent the outflow of water from the bathroom side to the undressing room side. In addition, the floor surface 11a of the dressing room 11 does not get wet with water. Since the lower frame 13b itself forms the water collecting groove 19, the water drained from the drain hole 45 of the groove 33 and the water drained through the gap between the lower frame 13b and the lower rail member 18 are formed. The collected water can be collected, and the collected water can be drained from the drain port 21 at the bottom.

Since water can be collected and drained by the lower frame 13b in this manner, it is assumed that there is no step between the floor surface of the washing room 3, the upper surface of the lower frame 13b, and the floor surface 11a of the dressing room 11. Barrier-free bathroom with no small steps
Further, the present invention is particularly effective for a bathroom having no drainage ditch near the opening 12 of the washing place 3. Further, since the lower frame 13b itself forms the water collecting groove 19, unlike the case where a separate drainage groove is provided on the undressing room side of the lower frame, the structure is simplified and the size of the lower frame 13b is reduced. be able to.

Below the lower frame 13b, a shape having a function of catching water leaking from the periphery of the lower frame 13b (water trap groove shape).
Is provided around the lower frame 13b, for example, the joint between the lower frame 13b and the vertical frame 13c, the lower frame 13b.
Water leaking from the joint between the lower frame receiving material 20 and the joint between the lower frame receiving material 20 and the washing pan 4 can be captured without falling downward. The water captured by the lower frame receiving material 20 is drained from the drain port 30 at the bottom thereof together with the water collected by the lower frame 13b through the drain guide 31 and the drain pipe 32 into the waterproof pan 7, for example. Will be.

Therefore, the lower frame 13 is provided by the lower frame receiving material 20.
Since it is possible to prevent the water leaking from the periphery of b from falling down, it is possible to prevent water leaking downstairs, particularly when the bathroom 1 is provided on the second floor or higher of the building.
The lower frame receiving member 20 is provided separately from the lower frame 13b, and the closing members 24a, 24b of the lower frame receiving member 20 and the lower frame 1 are provided.
3b is not in contact, the opening 12 is distorted and the vertical frame 13
Even if stress is applied to the joint between c and the lower frame 13b, no stress is applied to the closing members 24a and 24b, and therefore, the water capturing function of the lower frame receiving material 20 does not deteriorate.

Although the preferred embodiments of the present invention have been described in detail with reference to the drawings, the present invention is not limited to the above-discussed preferred embodiments, and various design changes and the like can be made without departing from the scope of the present invention. Is possible. For example, the present invention is applicable to all types of sliding doors such as a triple sliding door, a sliding door, and a single sliding door. The bathroom includes a shower stall without a bathtub.
In the above embodiment, the water collected by the lower frame 13b and the water captured by the lower frame receiver 20 are drained into the waterproof pan 7 through the drain pipe 32. It is not limited to this. The lower frame receiving material 20 is not limited to the above-described embodiment as long as it can capture water leaking from the periphery of the lower frame 13b. , A dish shape or the like. The groove 33 may be provided directly on the lower frame 13b. In the present invention, the lower frame water stop member 39 and the vertical frame water stop member 40 are used.
Is attached to the sliding door shoji. On the other hand, when the water stop member is mounted on the lower frame, the groove for the water stop member must be formed in the groove of the lower frame, so that the groove shape of the lower frame becomes complicated. In this case, it is difficult to form the protrusion 43a projecting downward from the mating frame in accordance with the groove shape, and it is not possible to sufficiently suppress the lateral running of water in the groove. Further, in the present invention, the cross-sectional shape of the groove is a rectangle with an upper side, but may be a trapezoid with a smaller lower side. This prevents the protrusion 43a from being damaged when the protrusion 43a is set in the groove when the shoji is erected.

[0041]
