Description

  The present invention relates to a joinery, and more particularly, to a joinery that can prevent water leakage from the bathroom to the dressing room side and achieve further barrier-free operation.

  In recent years, barrier-free types with a level difference of 20 mm or less between the bathroom and the dressing room are often used as fittings attached to the entrance between the bathroom and the dressing room in order to accommodate the elderly and the disabled. ing. As such a barrier free type fitting, there exists a thing shown in patent document 1, for example.

  FIG. 7 is a longitudinal sectional view showing a conventional barrier-free type fitting shown in Patent Document 1. As shown in FIG. As shown in FIG. 7, the conventional joinery 200 includes a frame body 210 attached to an entrance between the bathroom and the dressing room, and a shoji 220 attached to the frame body 210 so as to be opened and closed. A drainage groove 211 </ b> A is formed in the lower frame 211 constituting the frame body 210 along the longitudinal direction of the lower frame 211. The drainage groove 211A is connected to the bathroom via holes 211B and 211C formed at the end of the lower frame 211 in the longitudinal direction.

  Further, a sealing material 230 is attached to the dressing chamber side of the lower frame 211 from the drain groove 211A. The seal member 230 protrudes upward and abuts on a seal piece, which will be described later, attached to the side of the dressing room of the shoji 220. Further, an attachment 240 is attached to the bathroom side of the drainage groove 211A of the lower frame 211. The attachment 240 is formed with an inclined surface 240A that becomes lower toward the bathroom side, so that the floor surface of the dressing room and the floor surface of the bathroom are gentle. Further, a seal piece 250 (250A) that is in contact with the upper surface of the attachment 240 is attached to the bathroom side surface of the lower arm 221 of the shoji 220. In addition, a seal piece 250 (250B) similar to the above is also attached to the side of the dressing room in the lower collar 221 of the shoji 220.

According to such joinery 200, even if water flows from the bathroom toward the dressing room, the flowing water is blocked by the bathroom-side seal piece 250A and returned to the bathroom. Further, as shown by an arrow P, the water that has flowed over the seal piece 250A to the dressing room side is blocked by the seal piece 250B and the sealing material 230 on the dressing room side, and flows into the drain groove 211A. The water that flows into the drain groove 211A is returned to the bathroom through holes 211B and 211C formed in the lower frame 211. Further, when water overflows in the bathroom, the overflow water flows backward from the holes 211B and 211C to the drain groove 211A side, and this overflowed water is a seal attached to the lower frame 211. It is blocked by the material 230 and stays in the drain groove 211A, and finally returned to the bathroom from the hole. Therefore, according to the joinery 200, barrier-free and prevention of water leakage from the bathroom to the dressing room can be achieved.
Japanese Patent Laid-Open No. 2002-322884

  However, in order to prevent water leakage from the bathroom to the dressing room side, a drain groove 211A is formed along the longitudinal direction of the lower frame 211, and a seal member 230 that protrudes toward the shoji 220 is attached to the lower frame 211. Therefore, a toe, a wheelchair wheel, or the like may be caught in the drain groove 211A or may be caught by the protruding seal material 230. For this reason, there is a need for a joinery that can be made even more barrier-free.

  An object of the present invention is to provide a joinery that can prevent water leakage from the bathroom to the dressing room side and can be further barrier-free.

  The present invention is attached to a doorway between a bathroom and a dressing room, and is configured by an upper frame, a lower frame, and left and right vertical frames. The lower frame includes an upper surface portion having substantially the same height level as the floor surface of the bathroom, and an upright portion that rises upward from the dressing room side in the upper surface portion. An attachment that covers the upper surface and forms a hollow space between the upper and lower vertical frames is attached between the left and right vertical frames, and the shoji is attached to the bathroom side and the dressing room side. Seal pieces that are in contact with each other, and the attachment includes a first communication portion that communicates the gap between the seal pieces with the shoji and the hollow space, the hollow space, and the bathroom. The A second communication portion is formed to be passing, and the rising portion and the attachment, characterized in that it directly or indirectly in contact.

According to the present invention, when water flows from the bathroom, the flowing water is returned to the bathroom by the bathroom-side seal piece attached to the shoji. In addition, when a stronger flow comes, this water flows over the bathroom side seal piece to the seal piece on the dressing room side. In this case, the water is blocked by the seal piece on the dressing room side. After that, it is guided to the hollow space via the first communication portion formed in the attachment between the seal pieces. Thereafter, the water guided to the hollow space passes through the upper surface portion of the lower frame and is discharged from the second communication portion formed in the attachment to the bathroom side. Therefore, it is possible to reliably prevent water leakage from the upper side of the attachment to the dressing room side.
For example, when a large amount of water flows from the bathroom, the flowing water may flow back to the hollow space in the attachment via the second communication portion. However, since the attachment and the upright part of the lower frame are in direct or indirect contact with each other, water does not leak from the gap between the attachment and the lower frame to the dressing room side. For this reason, the hollow space temporarily functions as a water storage space, and the water accumulated in the hollow space is finally discharged from the second communication portion to the bathroom side. For this reason, it can fully respond to the water flowing back into the hollow space in the attachment, and can reliably prevent water leakage to the dressing room.
Therefore, according to this joinery, the water stop performance between the bathroom and the dressing room can be sufficiently secured.

  In addition, since the drainage groove is not formed in the entrance / exit part between the bathroom and the dressing room by bringing the upper part of the lower frame into contact with the attachment, pedestrians such as elderly people can There is no possibility that the wheelchair will be caught or the wheelchair will be hindered, and a further barrier-free operation can be achieved.

  Here, a sealing material may be interposed between the upright portion and the attachment, and the upright portion and the attachment may be in contact with each other through the sealing material. According to such a configuration, since the gap between the upright portion and the attachment is reliably closed, it is possible to reliably prevent overflowing water from leaking to the dressing room side.

  In the above joinery, the vertical frame is attached to the vertical frame with a vertical seal material that contacts the closed shoji, and the first communication portion is closer to the bathroom side than the contact portion between the vertical seal material and the shoji. It may be formed. According to such a configuration, since the first communication portion is formed on the bathroom side with respect to the contact portion between the shoji and the vertical seal material, the overflow water that has entered the attachment from the second communication portion is the first communication portion. Even if the water overflows, the overflowed water is bounced back by the vertical sealing material and returned to the bathroom, so that it is possible to prevent water from leaking to the dressing room side.

  In the above joinery, the second communication portion may be formed in the vicinity of the left and right vertical frames at the substantially bathroom side end of the attachment. According to such a configuration, even if water flows from the hollow space of the attachment to the bathroom side through the second communication portion, the water flows in the vicinity of the left and right vertical frames, that is, the end portion side of the fitting. The appearance when water flows is improved as compared with the case where the second communication portion is formed in the central portion of the.

  In the above joinery, the upper surface portion may have an inclined surface that becomes lower toward the bathroom. According to such a configuration, by forming the inclined surface on the upper surface portion, the water accumulated in the hollow space can surely flow to the bathroom side.

  In the above joinery, the upper surface portion may be formed with a groove portion that destroys the surface tension of water accumulated on the surface of the upper surface portion. According to such a configuration, by forming the groove portion on the surface of the upper surface portion, it is possible to destroy the surface tension of the water accumulated in the hollow space and prevent water from accumulating on the surface of the upper surface portion. The inside can be kept clean.

  In the above joinery, the attachment may be detachably attached to the lower frame. According to such a configuration, by removing the attachment, the lower and inner sides of the attachment can be easily cleaned, which is hygienic.

  According to the joinery of the present invention, it is possible to prevent water leakage from the bathroom to the dressing room side and to achieve further barrier-free.

Further, the notches 63 </ b> A and 70 </ b> A are formed on the bathroom side with respect to the contact portion between the vertical seal member 80 and the shoji 20. For this reason, even if water overflows from the notches 63A and 70A, the notches 63A and 70A are located on the bathroom side with respect to the contact portion between the vertical seal member 80 and the shoji 20, so the overflow water is undressed. It can prevent leaking to the room side.

Next, the drainage function of the joinery 1 will be described.
When the water in the bathtub overflows, normally, the water flowing from the bathroom side is bounced back to the contact portion 55 of the attachment main body 51 and returned to the bathroom side. When a large amount of water flows strongly from the bathroom side, the flowing water flows up the inclined portion 54 to the horizontal portion 53 side, but on the bathroom side attached to the lower tub 22 It is bounced back by the sealing piece 34 and returned to the bathroom down the inclined portion 54. Furthermore, when the water flow is strong, the water flows over the bathroom side seal piece 34 to the dressing room side, but the flow is blocked by the seal piece 34 attached to the lower arm 22. Thereafter, the gas is guided to the left and right vertical frame 13 sides, that is, to both end portions in the longitudinal direction of the attachment 50, and flows from the notches 63 </ b> A and 70 </ b> A formed in the end portions of the cap 60 to the hollow space A. The water that has flowed into the hollow space A has its surface tension broken by the grooves on the surface of the upper surface portion 14 constituting the lower frame 12, and finally flows to the bathroom side according to the inclined surface of the upper surface portion 14, thereby finally The cap 60 is returned to the bathroom floor 2 from the hole 65A.

  In addition, when a shower is used in the bathroom, the water spray from the shower is applied to the side of the bathroom of the shoji 20, but the water was attached to the lower bowl 22 in the same manner as when the water in the bathtub overflowed. It is returned to the bathroom side by the sealing piece 34 on the bathroom side, or after flowing from the notches 63A and 70A to the hollow space A, it is returned to the floor 2 of the bathroom from the hole 65A of the cap 60.

  On the other hand, the water overflowing from the bathtub may flow backward from the bathroom to the hollow space A below the attachment body 51 through the hole 65 </ b> A formed in the cap 60. By the way, since the gap between the attachment 50 and the lower frame 12 is sealed by the sealing material 30, water does not leak from the gap to the dressing room side. For this reason, the hollow space A, which is a substantially sealed space, functions as a water storage space, and the water flowing back from the hole 65A to the hollow space A is accumulated in the hollow space A. And after the water pressure of backflow water settled, the water collected in the hollow space A is discharged | emitted from the hole 65A to a bathroom. In addition, the water accumulated in the hollow space A may overflow from the notches 63A and 70A. However, as described above, the notches 63A and 70A are formed on the bathroom side with respect to the vertical seal member 80. There is no worry that water will leak into the dressing room.

According to this embodiment, there are the following effects.
Since the gap between the attachment 50 and the lower frame 12 is sealed by the sealing material 30, it is possible to reliably prevent water flowing backward from the hole 65A of the cap 60 from leaking from the gap to the dressing room side. . In addition, two seal pieces 34 are attached to the front and back sides of the lower rod 22, and notches 63A and 70A are formed in the horizontal portion 63 of the cap 60 to guide the water flowing from the bathroom side to the hollow space A. Since the water is drained from the hole 65A of the cap 60, the water flowing from the bathroom side to the horizontal portion 53 of the attachment main body 51 can be reliably returned to the bathroom side without leaking to the dressing room side. it can. Therefore, according to the joinery 1, sufficient water stopping performance can be ensured. In particular, since the horizontal portion 53 is configured such that water collected in the gap between the shoji 20 and the horizontal portion 53 is guided to the notches 63A and 70A, it is possible to prevent water from collecting in the gap.

  Moreover, since the inclined surface was formed in the upper surface part 14 of the lower frame 12, the water collected in the hollow space A can be guide | induced to the bathroom side. Moreover, since the groove | channel which destroys the surface tension of water was formed in the upper surface part 14, the water collected in the hollow space A can be guide | induced to the vertical frame 13 side. Therefore, since the water accumulated in the hollow space A can be guided to the hole 65A formed in the cap 60, the inside of the hollow space A can be kept dry to be sanitary.

  Further, the sealing material 30 is attached between the horizontal portion 53 and the attaching portion 16 to form a flat floor surface without a drainage groove as in the prior art, and the upper surface of the sealing material 30, the upper surface of the horizontal portion 53, and Since the upper surface 16A of the mounting portion 16 is configured to have substantially the same height level, there is no possibility that the elderly or the like may get caught in the foot or disturb the running of the wheelchair. Can be achieved. In particular, since the notches 63A and 70A are formed in the vicinity of the vertical frame 13, the notches 63A and 70A do not affect the entry and exit of the elderly and the like.

  Moreover, since the attachment 50 was comprised so that attachment or detachment was possible from the floor surface 2 of a bathroom, the space between the attachment 50 and the lower frame 12 can be easily cleaned by removing the attachment 50 suitably.
