Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seal structure for a fitting provided at an entrance of a so-called water place such as a bathroom or a shower room, and a fitting having the same.

[0002]

2. Description of the Related Art Conventionally, as a sealing structure for a fitting of this type, for example, Japanese Unexamined Patent Application Publication No. 2000-352 applied to three sliding doors.
The one described in Japanese Patent Publication No. 278 is known. In this three-sliding door, the bathroom floor and the undressing room floor have some steps, and a slope material provided on the bathroom side absorbs the steps. The lower frame is composed of a lower frame main body disposed so as to straddle the bathroom floor and the undressing room floor, and a lower frame mounting material disposed with a gap above the lower frame main body. The base of the slope material is hung on the bathroom side end. A seal member is interposed between each door body and the lower frame mounting member, and drainage leaking from the seal member is guided into a space formed between the lower frame mounting member and the lower frame main body. It has become. In addition, a valve-type water-blocking piece is suspended from the bathroom-side opening of this space, and the drainage guided into the space is drained from the bathroom side, passes through the water-blocking piece, and enters the bathroom. It is led to the side.

[0003]

In such a conventional fitting structure for a fitting, the space formed between the lower frame mounting member and the lower frame main body is located between the bathroom floor and the undressing room floor in the height direction. And the width of the lower frame in the expected direction limits the increase in internal volume. For this reason, there is a problem that the pressure fluctuation in the space used by the opening / closing operation of the water blocking piece cannot be appropriately absorbed, and the close contact portion of the seal member rises, thereby deteriorating the sealing performance.

[0004] It is an object of the present invention to provide a seal structure for a fitting capable of absorbing pressure fluctuations in a water stoppage space against a pulsating flow of drainage, and a fitting having the same.

[0005]

According to the present invention, a sealing structure for a fitting comprises a lower frame of a frame which is seated watertight on an edge of a waterproof floor on the indoor side, and a lower frame of a door facing the lower frame. In the sealing structure of the fitting for sealing the space, a lower frame attachment attached to the indoor side front portion of the lower frame and extending forward in the expected direction,
A first seal member interposed between the front end of the lower frame attachment and the waterproof floor, a second seal member interposed between the lower frame attachment and the indoor front portion of the lower frame, and a lower frame chamber A third seal member interposed between the outer rear portion and the outdoor rear portion of the lower frame, wherein the first seal member, the second seal member, and the third seal member form the lower frame attachment from below the lower frame attachment. It is characterized in that a single water stop space is formed over the lower side.

According to this configuration, when the drainage flowing through the waterproof floor reaches the fitting, the first seal member prevents the water from flowing into the water stop space below the lower frame attachment, and the second seal member lowers the water. Inflow to the water stop space below the frame is prevented. The drainage leaked from the first and second seal members is guided to the water stoppage space, but the third seal member prevents leakage to the outside of the room. On the other hand, when the drainage on the waterproof floor side can be drained, the drainage that has accumulated in the water stoppage space flows out to the drain port side of the waterproof floor from the gap between the waterproof floor and the both ends of the lower frame attachment. In this case, since a single water stop space is configured from the lower side of the lower frame attachment to the lower side of the lower frame, by extending the lower frame attachment sufficiently forward in the expected direction, Regardless of the width of the lower frame, the internal volume of the water stop space can be increased. For this reason,
Even if the drainage reaching the fittings pulsates, the pressure fluctuation in the water-stop space is easily attenuated, and there is no trouble such that the close portions of the seal members are lifted by the positive pressure in the water-stop space.

In this case, it is preferable that a cap member whose lower surface contacts the waterproof floor is attached to each side end of the lower frame attachment in the finding direction.

According to this configuration, the cap member allows
Inflow of drainage from both ends of the lower frame attachment into the water stop space can be prevented as much as possible. Further, after the drainage on the waterproof floor side is drained, the outflow of the drainage in the water stoppage space can be allowed.

[0009] In these cases, it is preferable that the lower frame is formed with an air flow path that connects the water stoppage space and the outdoor space.

According to this structure, even if pressure fluctuations occur in the water stoppage space due to pulsating drainage reaching the fittings, the pressure fluctuations can be released to the outdoor space as a flow of air. For this reason, the water stoppage space and the outdoor space can always be kept at the same pressure, pressure fluctuations can be appropriately absorbed, and floating of each seal member can be effectively prevented.

In these cases, it is preferable that the lower frame attachment is detachably attached to the lower frame, and the upper surface thereof is inclined forward and downward toward the waterproof floor.

According to this configuration, the lower frame attachment can be used as a slope member between the lower frame and the waterproof floor. That is, a step can be appropriately provided between the indoor waterproof floor and the outdoor floor, thereby improving the sealing performance. On the other hand, if the lower frame attachment is extended forward in the expected direction for a long time, the slope can be made a gentle slope with no uncomfortable feeling, and the internal volume of the water stop space can be increased.

In these cases, the third seal member comprises a lower frame side seal member attached to the lower frame and a lower frame side seal member attached to the lower frame. Are preferably close to each other.

According to this structure, since the lower frame side seal member and the lower frame side seal member which are in close contact with each other constitute the third seal member, a sealing structure for bringing flexible members into close contact with each other is provided. Therefore, the sealing property of this portion can be remarkably improved.

A fitting according to the present invention is characterized by comprising the fitting sealing structure according to any one of the first to fifth aspects.

According to this configuration, even when there is almost no step between the waterproof floor on the indoor side and the floor on the outdoor side with the fitting therebetween, the drainage rushing from the waterproof floor side is securely sealed by the fitting. Can be.

Therefore, the undressing room-side intermediate seal piece 71 and both the undressing room-side seal pieces 63, 63 are continuous without any step in the finding direction, and the lower frame seal member 26 is in close contact with them. That is, the undressing room-side intermediate sealing piece 71, both the undressing room-side sealing pieces 63, 63, and the lower frame sealing member 26 constitute a sealing line on the undressing room B side.

On the other hand, as shown in FIG. 3, each cap member 29 attached to each side end of the lower frame attachment 28 is
The upper surface and the front surface are formed so as to be flush with the lower frame attachment 28, and the rear surface thereof
3 and the lower surface thereof are formed so as to be in full contact with the waterproof pan P, respectively. That is, each cap member 29 closes each side end of the lower frame attachment 28 in a state of being in contact with the outer end of the attachment seal piece 30 inside. This prevents a rapid inflow of drainage to the lower side of the lower frame attachment 28, but allows a gentle inflow and outflow of drainage from a minute gap between the cap member 29 and the waterproof pan P.

As described above, the attachment seal piece 3
0, a water stop configured by the bathroom side sealing piece 62, the undressing room side sealing piece 63, and the lower frame sealing member 26 so that the drainage of the bathroom A does not flow directly into the lower side of the lower frame attachment 28 and the lower frame 42. A space 75 is formed. More specifically, each of the seal pieces 30, 62, 63 and each of the seal members 26, the lower frame attachment 28 and the lower frame 42
And the lower frame main body 21 and an edge of the waterproof pan P (both ends in the finding direction are omitted), and a water blocking space 75 is formed.

In this case, the drainage leaked from the attachment seal piece 28 or the bathroom side seal piece 62 flows into the water stoppage space 75, but after the drainage on the waterproof pan P is closed, the water stoppage space 75 is closed. The drainage flows out from the gap of the cap member 29 onto the waterproof pan P. For this reason, the catching piece 23 of the lower frame 12 is provided with a drainage opening 76 that allows drainage collected on the lower frame main body 21 to flow out onto the waterproof pan P (the lower position of the lower frame attachment 28) in the direction in which it is found. A plurality is formed.

As described above, since not only the gap between the lower frame 42 and the lower frame 12 but also the gap between the lower frame attachment 28 and the waterproof pan P is integrally formed as the water stop space 75, for example, the overflow of the bath tub may occur. Even if the pulsating drainage is pushed toward the lower frame 12, the pressure fluctuation in the water stop space 75 is absorbed, and the floating of the seal pieces 26, 30, 62, and 63 is suppressed.

In this embodiment, an air flow passage 77 is formed to communicate the water stop space 75 with the inside of the undressing room B in order to absorb the pressure fluctuation in the water stop space 75 well. That is, the lower wall constituting the lower frame hollow portion 51 has the first
An air vent hole 78 is formed (a plurality of holes in the finding direction).
An air vent hole 79 is formed (a plurality of holes in the finding direction), and the hanging part 60 on the bathroom side and the undressing room side of the lower frame 42 is provided.
a, 61a, the first air vent hole 78, the lower space of the lower frame hollow portion 57, and the second air vent hole 79,
An air channel 77 is formed.

As described above, by allowing the water stop space 75 to communicate with the inside of the undressing room B via the air flow path 77, the air in the water stop space 75 flows out appropriately as the pressure in the water stop space 75 fluctuates. The water stoppage space 75 and the undressing room B can always be kept at the same pressure. That is, the pressure fluctuation in the water stop space 75 is reliably absorbed, and the seal pieces 30 and 6 due to the positive pressure are absorbed.
2, 63 and the sealing member 26 can be prevented from rising.

Next, the seal structure around the vertical frame 13 will be described with reference to FIG. As shown in FIG.
Between the vertical frame 44 on the door bottom side and the vertical frame 13 facing the vertical frame 44, the vertical frame sealing piece 36 is provided on the bathroom A side, and is positioned on the undressing room B side. A seal member 37 is provided. Also, inside the hollow of the vertical frame 44, both upper and lower hinge pins 54a, 54b and both upper and lower sliders 55a, 55
b is incorporated, and the outer peripheral surface 44a of the vertical frame 44 has a semicircular arc portion that is concentric with the upper and lower hinge pins 54a and 54b. Then, the vertical frame seal mounting portion 34

And a sponge-like seal portion 83 disposed therebetween.
The support base 81 and the two seal pieces 82, 82 are integrally formed by composite extrusion using the support base 81 as a hard resin and the two seal pieces 82, 82 as a soft resin.

The sponge-like seal portion 83 is made of a foamed material such as urethane, and is adhered to the support base 81 on the back side so as to be sandwiched between two seal pieces 82, 82 contacting on both sides. . Further, the sponge-shaped seal portion 83 is formed in a short length, and is provided only between the lower end portions of the vertical frame 13 and the vertical frame 44. That is, the two seal pieces 82 extend substantially over the entire length of the vertical frame (vertical frame 44) 13 in the longitudinal direction, while the sponge-like seal portion 83 forms the vertical frame (vertical frame 44). Reference numeral 13 is from the bottom to a height of about 100 mm. The tip of each seal piece 82
The sponge-shaped seal portion 83 slightly protrudes from the front end, and the front end surface of the sponge-shaped seal portion 83 is formed to be flat and concave in an arc shape following the outer peripheral surface 44 a of the vertical frame 44.

On the other hand, on the back side of the support base 81, a locking projection 81a located on the undressing room B side and a locking projection 81b located on the bathroom A side are integrally formed. Correspondingly, the seal member mounting piece 35 of the vertical frame 13 has
A latching piece 35a located on the undressing room B side and a locking piece 35b located on the bathroom A side are integrally formed. The composite seal member 37 is mounted on the vertical frame 13 such that the locking projection 81b is pushed into the locking piece 35b while the locking projection 81a is locked on the locking piece 35a. That is, the composite seal member 37 is mounted on the vertical frame 13 in the form of a pressed edge, and in this state, the support base 81 is directed tangentially to the arc-shaped vertical frame 44.

As described above, since the contact area with the vertical frame 44 can be extremely increased by using the composite sealing member 37, the vertical frame 13 and the vertical frame 44, which need to particularly enhance the sealing property, can be used. Can be reliably sealed between the lower end portions of the. Further, since the sponge-like seal portion 83 is formed in a short length, the sliding resistance with respect to the vertical frame 44 can be reduced, and the smooth opening and closing operability of the door body 3 is not impaired. In addition, the composite seal member 37 can be easily attached to the vertical frame 13 and can be easily replaced by a ridge type. Although the description is omitted, a similar seal structure is provided between the vertical frame 44 and the vertical frame 13 on the door end side of the door body 3 (see FIG. 2).

Next, referring to FIG. 6 and FIG.
First and second modified examples of the double seal structure will be described. As shown in FIG. 6, in the seal structure of the first modified example, the lower frame seal member 85 attached to the lower frame seal attachment portion 25 of the lower frame 12 has a cross-sectional shape that falls down on the bathroom A side. This modification does not ask whether the lower frame attachment 28 is present.

The lower frame seal member 85 includes a mounting portion 85a mounted on the lower frame seal mounting portion 25, a seal base 85b extending from the mounting portion 85a to the bathroom A side, and a seal base 85b.
And a sealing piece 85c that extends obliquely so as to fall down onto the bathroom A side from the upper end of the housing. The seal piece portion 85c in the free state has substantially the same height as the lower frame parting piece 22, and is bent so as to be raised by the undressing room side seal piece 63 with the closing of the door body 3, and is closely attached thereto. I do. With such a configuration, even when the user steps on the lower frame seal member 85 when entering or leaving the door body 3 opened, the user does not feel uncomfortable and can extend the life of the lower frame seal member 85. Moreover, the sealing performance is not impaired.

As shown in FIG. 7, in the seal structure of the second modification, the bathroom-side seal piece 87 is rotatably mounted on the inward seal mounting portion 66 of the lower frame 42 within a predetermined angle range. I have. The bathroom-side seal piece 87 is integrally formed of a mounting base 87a having a circular cross section and a seal piece 87b extending from the mounting base 87a by composite extrusion. On the other hand, the circular groove-shaped inward seal mounting portion 66 is formed so that its inner peripheral surface is slightly thicker (to the extent that watertightness is not impaired) than the mounting base portion 87a.
7, the range of rotation in the expected direction is regulated.

That is, the bathroom-side sealing piece 87 is
When it is opened, it rotates so as to contact the waterproof pan P and tilts toward the undressing room B, and when it closes, it rotates so as to tilt toward the bathroom A. Thereby, even when the front end of the bathroom-side seal piece 87 touches the waterproof pan P when opening and closing the door body 3, the waterproof pan P is not damaged, and there is no resistance to the opening and closing of the door body 3.
