Description

  The present invention relates to a water stop structure for bathroom fittings such as a bathroom folding door, a bathroom door, and a bathroom sliding door provided at the entrance of a bathroom, and a bathroom fitting including the same.

Conventionally, what applied to the bathroom sliding door is known as a water stop structure of this kind of bathroom fitting. This bathroom sliding door is composed of three sliding doors of a suspended type and a sliding door frame on which the three sliding doors are mounted so as to be freely opened and closed. The lower frame of the sliding door frame is composed of a lower frame body that forms a drainage channel that slopes down toward the bathroom, and a lower frame attachment placed on the upper surface of the lower frame body, and the upper surface of the lower frame attachment is undressing It is disposed substantially flush with the room floor. In addition, the lower frame attachment is formed with three rows of guide grooves that face the guide pieces hanging from the lower arm of each sliding door, and each guide groove is provided with a lower frame seal member that is in sliding contact with each guide piece. . That is, a water stop line for three sliding doors is constituted by three lower frame sealing members that seal the three sliding doors.
On the other hand, in order to receive the drainage leaked from the water stop line to the dressing room side, a horizontal piece having a large number of openings is extended on the dressing room side of the lower frame body, and the lower side of the horizontal piece Has a groove formed in the drainage path. And the drainage (leakage) which flowed down from each opening part is guide | induced to the bathroom side via a drainage path | route from a groove part. In addition, a plurality of drainage holes connected to the drainage path are formed in the bathroom-side partition that constitutes the groove, and an airtight material for preventing a backflow is disposed in the vicinity of the drainage hole so as to backflow the drainage path. This prevents the inflow of drainage into the groove.
JP-A-9-112136

In such a conventional water stop structure for bathroom fittings, if a large amount of drainage from the bathroom washer flows backward through the drainage channel and leaks from the airtight material for preventing backflow, depending on the amount of leakage, the groove becomes full and the horizontal piece opens. May overflow from the hole. There was a problem that the drainage once overflowed from the opening part flowed out to the dressing room floor without obstacles.
However, if the water tightness of the airtight material is increased, the amount of drainage (backflow) of drainage from the airtight material can be suppressed. However, if the watertightness of the airtight material is increased, the drainage from the groove side becomes difficult to flow, and the drainage leaking from the water stop line fills the groove and leaks to the dressing room floor.

  The present invention is capable of guiding drainage leaked from the water stop line to the dressing room side to the bathroom side, and effectively preventing the drainage of the waste water flowing back to the dressing room floor from flowing out to the floor of the dressing room. It is an object to provide a structure and a bathroom fitting provided with the structure.

  The water stop structure for a bathroom joinery of the present invention includes a seal member that seals between the lower frame of the joinery frame body and the lower arm of the closed fixture main body, and the bathroom join fixture that stops the drainage of the bathroom by the seal member. In the waterstop structure, the lower frame is disposed substantially flush with the dressing room floor in the vicinity of the dressing room side of the seal member, receives a drainage leaking from the seal member and forms a drainage hole, A water return member that is projected upward between the plate and the dressing room floor and made of an elastic material, and an inclined portion that guides the drainage that flows down from the drainage hole of the leak receiving plate to the bathroom floor. Features.

According to this configuration, the drainage leaked from the sealing member constituting the water stop line to the dressing room side flows on the leak receiving plate, flows down from the drain hole to the lower side of the leak receiving plate, and on the inclined portion on the bathroom. It flows toward the floor. On the other hand, when the drainage in the bathroom flows backward through the reverse path, the drained water flowing back is pressed by the leak receiving plate, and even if it overflows from the drainage hole, the water return member prevents water leaking to the dressing room floor. The bathroom drainage flows from the washing area to the lower frame when it cannot be swollen by the drain trap, but it gradually decreases over time. For this reason, since the waste water which overflowed from the drain hole and accumulated on the leak receiving plate is guided to the bathroom from the drain hole with the passage of time, the leak to the dressing room floor can be effectively prevented.
On the other hand, the water return member that dams up the drainage on the leak receiving plate is made of an elastic material that protrudes upward. .
The seal member may be either a member attached to the lower frame and in close contact with the lower heel, a member attached to the lower heel and in close contact with the lower frame, or a configuration provided with both of them.

  In this case, the lower frame further includes a seal mounting portion that rises from the inclined portion and is fitted with a seal member, and a water return mounting portion that rises from the inclined portion and is fitted with a water return member. It is preferable that a drainage buffer for temporarily storing drainage from the bathroom is configured in the lower space of the water leakage receiving plate surrounded by the portion and the inclined portion.

  According to this configuration, since the waste water flowing backward from the bathroom is temporarily stored in the drain buffer, it is possible to prevent the waste water from overflowing from the drain hole of the leak receiving plate, and until the reduced water state on the bathroom side is started. The time lag can be earned.

  In this case, it is preferable that the water leakage receiving plate is detachably mounted between the seal mounting portion and the water return mounting portion.

  According to this configuration, the inside of the drain buffer can be cleaned by removing the leak receiving plate.

  In these cases, a communication channel that guides drainage from the drainage buffer to the bathroom floor is formed in the gap between the seal mounting portion and the inclined portion, and the seal member allows the drainage of drainage from the communication channel and backflow. It is preferable that a backflow prevention piece for preventing the above is formed.

  According to this configuration, it is possible to effectively prevent the backflow of drainage flowing from the bathroom, and appropriately guide the drainage from the drainage buffer to the bathroom after the backflow is settled. Further, by providing the sealing member with a function of preventing backflow, the number of parts and the number of assembling steps can be reduced.

  Another water-stop structure for a bathroom fitting according to the present invention includes a seal member that seals between a lower frame of a joinery frame body and a lower heel of a closed fixture main body, and the bathroom drains the bathroom with the seal member. In the water-stopping structure of joinery, the lower frame is disposed in the vicinity of the dressing room side of the sealing member, receives the drainage leaked from the sealing member and flows down from the drainage hole of the leakage receiving plate. And a lower frame parting piece that is disposed on the dressing room side of the leak receiving plate and presses the end of the dressing room floor, and the upper surface of the leak receiving plate is closed to the lower frame. It is arranged at a position slightly lower than the upper surface of the piece.

  According to this configuration, since the upper surface of the lower frame parting piece is located higher than the upper surface of the water leakage receiving plate, the upper surface of the end part on the dressing room side of the water leakage receiving plate and the upper surface of the end part on the bathroom side of the lower frame parting piece are raised. The part tied in the vertical direction functions as a dam that prevents water leaking from the lower seal member to the floor of the dressing room from entering the leak receiving plate. Therefore, similarly to the water stop structure of the bathroom fitting described above, drainage leaked from the water stop line to the dressing room side can be guided to the bathroom side, and drainage of the waste water flowing back to the dressing room floor can be effectively discharged. Can be prevented.

  In these cases, it is preferable to further include a backflow prevention mechanism that allows the drainage of the wastewater from the drainage holes and prevents backflow.

  According to this configuration, it is possible to prevent the backflowed drainage from overflowing from the drainage hole of the leak receiving plate. In addition, as a backflow prevention mechanism, the sheet-like check valve etc. which were arrange | positioned at the back surface of the water leak receiving plate can be used, for example. That is, this check valve has a sheet-like valve body partly attached to the drain hole forming edge on the back surface of the leak receiving plate and the drain hole forming edge as a valve seat.

  In this case, it is preferable that the backflow prevention mechanism is constituted by a float housed under the leak receiving plate and a valve body that is provided in the float and closes the drain hole when the float is lifted.

  According to this configuration, when the drainage due to the backflow accumulates in the drainage buffer and the water level rises, the float rises and the valve body closes the drainage hole. Conversely, when the water level of the drain buffer drops, the float sinks and the valve element opens the drain hole. That is, it is possible to prevent the backflowed drainage from overflowing from the drainage holes of the leak receiving plate, and to allow the drainage on the leak receiving plate to smoothly flow down to the drain buffer through the drainage holes. In addition, the valve body may be configured by a part of the upper surface of the float or may be configured separately from the float.

  The bathroom fitting according to the present invention includes the water stop structure for the bathroom fitting described above.

  According to this structure, the bathroom fitting which can prevent effectively the leakage of the bathroom drainage to the dressing room side can be provided.

  As described above, according to the water stop structure of the bathroom fitting and the bathroom fitting of the present invention, drainage leaked from the water stop line constituted by the seal member to the dressing room side can be smoothly guided to the bathroom side, It is possible to effectively prevent the drainage of the bathroom that flows back to the floor of the dressing room. Therefore, the reliability of the bathroom fitting can be improved with respect to the water stoppage.

  Hereinafter, with reference to the accompanying drawings, description will be given of a case in which a water stop structure for a joinery bathroom fitting according to an embodiment of the present invention is applied to a bathroom joinery. This bathroom has a barrier-free design with almost no difference between the bathroom and the dressing room, and a bathroom folding door is attached as a bathroom fitting at the entrance / exit between the bathroom composed of a unit bath and the dressing room. FIG. 1 is a longitudinal sectional view of a bathroom folding door, and FIG. 2 is a transverse sectional view thereof. As shown to both figures, the bathroom folding door 1 is comprised by the folding door frame 2 (joining-body frame) which comprises an entrance-and-exit opening part, and the door body 3 (jointing-tool main body) supported by the folding door frame 2 so that opening and closing is possible. Yes. Further, the bathroom floor constituted by the waterproof pan 5 of the unit bath, the lower frame 32 of the folding door frame 2, and the dressing room floor 6 of the dressing room B are substantially flush with each other so that no stepped portion is formed. It is installed.

  The door body 3 is composed of a left door body 3a, a right door body 3b, and a connecting member 4 that is foldably connected in a state of being in contact with each other. The right door body 3b is opened by being folded into the bathroom A while sliding along the folding door frame 2, and is closed by the reverse procedure.

  Each of the left and right door bodies 3a and 3b has a vertical rod 14 and a connecting vertical rod 15 assembled on an upper rod 11, a lower rod 12 and an intermediate rail 13 each made of an aluminum shape, etc., and is made of resin. The upper and lower panel bodies 16 are incorporated. The middle rail 13 is integrally formed with a handle 18 on the dressing room B side, and a towel rack 19 that also serves as a handle is attached to the right door 3b on the bathroom A side. A latch mechanism 20 is incorporated in the connecting vertical rod 15 of the left door body 3a, and a closing lock mechanism 21 (also used as a child lock) is incorporated in the connecting vertical rod 15 of the right door body 3b. In addition, a detaching mechanism 22 (emergency detaching mechanism) for detaching an upper slider 24a described later from the upper guide rail 36 is incorporated in the vertical rod 14 of each door 3a, 3b.

  Furthermore, the upper slider 24a and the lower slider 24b are respectively attached to the vertical rods 14 of the door bodies 3a and 3b via upper and lower pin hinges 23a and 23b with the lower side being a gravity hinge. The upper slider 24a and the lower slider 24b are slidably supported by an upper guide rail 36 and a lower guide rail 71 of the folding door frame 2 described later. However, in order to open one side, the upper and lower sliders 24a and 24b of the left door 3a are fixed to the upper and lower guide rails 36 and 71, respectively. That is, the left door body 3a rotates via the upper and lower pin hinges 23a and 23b when opening and closing. For this reason, the left door 3a is opened while gradually rising in the initial opening operation, and is closed while gradually lowering in the final operation of closing.

  On the other hand, the folding door frame 2 is formed by framing an upper frame 31, a lower frame 32, and left and right vertical frames 33, 33 each made of an aluminum shape, and is joined to the waterproof pan 5 in a watertight manner. The upper frame 31 includes a horizontal “L” -shaped vertical portion 35a and a horizontal portion 35b extending horizontally from the lower end of the vertical portion 35a to the dressing room B side. An upper guide rail 36 projecting downward at an intermediate position in the prospective direction of the horizontal part 35b, an upper frame parting piece 37 extending horizontally from the end of the horizontal part 35b on the dressing room B side, and a dressing room of the horizontal part 35b The upper seal mounting portion 38 extending downward from the end portion on the B side is integrally formed. An upper frame seal member 39 that is in close contact with each upper collar 11 is mounted on the upper seal mounting portion 38.

  Similarly, each vertical frame 33 includes a vertical frame main body 40 having a rectangular hollow portion that is long in the prospective direction, and a vertical frame parting piece 41 in which an end on the dressing room B side of the vertical frame main body 40 is extended in the prospective direction. The vertical frame parting piece 41 is integrally formed with the vertical seal mounting part 42 extending inward from the base part. Each vertical seal mounting portion 42 is mounted with a vertical frame seal member 43 that is in close contact with each vertical rod 14.

  Next, the water stop structure between the lower frame 32 and the lower rod 12 will be described in detail with reference to an enlarged view of FIG. A downward seal member 56 that is located on the bathroom A side and is in close contact with the lower guide rail 71 is provided at the lower end of the lower basket 12. Further, on the dressing room B side of the lower heel 12, a protruding piece 57 is formed on the cross-sectional crank to which a lower frame seal member 73 described later is in close contact. That is, when the doors 3a and 3b are closed, the downward seal member 56 comes into close contact with the bathroom A side of the lower guide rail 71, thereby forming a water stop (primary water stop line) line on the bathroom A side. A lower frame seal member 73, which will be described later, is in close contact with the projecting piece 57, thereby forming a water stop line (secondary water stop line) on the dressing room B side as a main water stop line.

  On the other hand, the lower frame 32 is placed on the support portion 5a of the waterproof pan 5 extending in an “L” shape on the side of the dressing room B, and the lower frame main body 61 spanned between the floor 6 and the lower frame body, The frame main body 61 is seated on the upper surface of the undressing room B side, and is configured by a water leakage receiving plate 62 whose upper surface is substantially flush with the undressing room floor 6.

  The lower frame body 61 includes a vertically long lower frame hollow portion 66 placed on the support portion 5 a of the waterproof pan 5, and an inclined portion 67 that extends the upper end portion of the lower frame hollow portion 66 to the end position of the dressing room floor 6. And a lower frame parting piece 68 that extends from an upper end portion of a water return mounting portion 81 to be described later to the dressing room B side and presses the dressing room floor 6. In addition, a seal is made between the upper end of the lower frame hollow portion 66 on the bathroom A side and the waterproof pan 5 with a caulking material or the like.

  The inclined portion 67 (and the lower frame hollow portion 66) is formed such that its upper surface is slightly inclined downward toward the bathroom floor of the waterproof pan 5, and the upper surface of the inclined portion 67 on the bathroom A side is A lower guide rail 71 for slidably supporting the door bodies 3a and 3b is formed by the lower slider 24b. Further, the lower guide rail 71 is formed with a pair of cutout portions (not shown) that are partially cut away so as to have a minimum opening area that allows drainage to flow down at both ends in the direction of finding. Yes. A pair of communication openings may be formed at the base of the lower guide rail 71 instead of the pair of notches.

  In addition, a lower seal mounting portion 72 having a seal mounting groove 72 a having an inverted “C” -shaped cross section is formed at an intermediate portion in the prospective direction of the inclined portion 67 so as to rise from the inclined portion 67. The lower seal mounting portion 72 is mounted with a lower frame seal member 73 that is upside down and has a “J” -shaped cross section projecting toward the protruding piece 57 of each door body 3a, 3b. The lower frame seal member 73 is made of an air tight material, and protrudes upwards from the protrusion 73a directly toward the seal mounting groove 72a toward the bathroom A, and closes the door bodies 3a and 3b. In this state, the upper seal piece 73b that is in close contact with the protruding piece 57 and the backflow prevention piece 73c that extends downward from the convex portion 73 toward the bathroom A and is in close contact with the upper surface of the inclined portion 67 are integrally formed. Further, on the back surface of the lower seal mounting portion 72, a support piece 72b for supporting the water leakage receiving plate 62 is protruded on the dressing room B side, and drainage openings 78 ( A communication channel) is formed. The drainage opening 78 is a part that guides drainage from a drainage buffer 91 to be described later to the bathroom A side, and is formed by slightly cutting a part of the lower seal mounting portion 72 to allow the drainage to flow down. It has the smallest possible opening area.

  Therefore, as described above, the lower frame seal member 73 constitutes a secondary water stop line by the upper seal piece 73b, and effectively prevents the backflow of drainage flowing from the bathroom by the backflow prevention piece 73c. In addition, after the reverse flow is settled, the drainage from the drainage buffer 91 is allowed to flow down, and then appropriately guided to the bathroom. Thus, by providing the lower frame seal member 73 with a function of preventing backflow, it is possible to reduce the number of parts and the number of assembly steps.

  The lower frame parting piece 68 is a part that is fixed to the dressing room floor 6 with screws in the lower frame 32, and a water return mounting part that rises from the inclined part 67 between the lower frame parting piece 68 and the inclined part 67. 81 is interposed, and the water return mounting portion 81 is formed with a water return mounting groove 81a having an upward “C” -shaped cross section. A water return member 82 made of an elastic resin having an upside down “J” -shaped cross section is mounted upward in the water return mounting groove 81a, and the dressing chamber of the water leakage receiving plate 62 is provided at the front end thereof. It comes in close contact with the B side upper surface. In this case, the water return member 82 includes the upper surface of the lower seal mounting portion 72 disposed substantially flush, the upper surface of the water leakage receiving plate 62, and the upper surfaces of the lower frame parting pieces 68 (all of which are substantially flush with the dressing room floor 6). ) Protrudes upward at the same height as the lower frame seal member 73, and functions as a weir so that the water drained on the water leak receiving plate 62 does not flow out to the dressing room B side. The water return member 82 is preferably made of an air tight material in the same manner as the lower frame seal member 73 in consideration of footwear.

  On the other hand, the water leakage receiving plate 62 has an upper surface substantially flush with the dressing room floor 6 and receives drainage leaked from the lower frame seal member 73 toward the dressing room B, and a plate body 62a. The short hanging piece 62b that hangs down from the bathroom A side end portion and the long hanging piece 62c that hangs down from the end portion of the plate body 62b in the dressing room B are integrally formed. The plate main body 62a is formed with a plurality (2 to 5) of drain holes 86 arranged at equal intervals in the direction of finding. The water leakage receiving plate 62 is detachably mounted so as to fit between the lower seal mounting portion 72 and the water return mounting portion 81. In the mounted state, the short hanging piece 62b is attached to the lower seal mounting portion 72. While being supported by the support piece 72b, its side surface is in close contact with the back surface of the lower seal mounting portion 72, and the long hanging piece 62b is supported by the inclined portion 67 and its side surface is in close contact with the side surface of the water return mounting portion 81. ing.

  Then, in the lower space of the water leakage receiving plate 62 surrounded by the lower seal mounting portion 72, the water return mounting portion 81 and the inclined portion 67, the water leakage receiving plate leaks from the lower frame seal member 73 to the dressing room B side. A drainage buffer 91 that guides the drainage flowing down from the 62 drainage holes 86 to the bathroom side is configured. Further, the drainage buffer 91 has a function of temporarily storing drainage that has flowed back through the inclined portion 67 and that has reached its flow velocity and flow rate by the notch and the drainage opening 78.

  The water leakage receiving plate 62 is detachably mounted so that the drainage buffer 91 can be easily cleaned. However, the junction between the short hanging piece 62a and the lower seal attaching portion 72, the long hanging piece 62b, and water In order to further enhance the water tightness at the joint portion with the return mounting portion 81, sealing may be performed with a dry sealing material or the like at both joint portions.

  Then, drainage leaked from the lower frame seal member 73 to the leak receiving plate 62 is allowed to flow into the drain buffer 91 so as to face each drain hole 86 from below, and drainage temporarily accumulated in the drain buffer 91. A reverse flow prevention mechanism 92 is provided to prevent the water from flowing out onto the water leakage receiving plate 62.

  The backflow prevention mechanism 92 includes a float 96 housed in the drain buffer 91 and a position shift prevention pin 97 projecting from the center of the upper surface of the float 96. The misalignment prevention pin 97 includes a head portion 97a having a diameter smaller than the diameter of the drain hole 86 and a shaft portion 97b screwed into the float 96, and the level of drainage in the drainage buffer 91 is low (or there is no drainage). ), The backflow prevention mechanism 92 is in a state where the head portion 97a of the misalignment prevention pin 97 is housed in the drainage hole 86 of the water leakage receiving plate 62, and restricts the position of the float 96. On the other hand, the float 96 is formed in a bell shape that is hollow inside and has a lower end opened, and the upper surface functions as a valve body that closes the lower end portion (valve seat) of the drain hole 86 when ascending. But you may make it provide a rubber-made sheet | seat (valve body) on the upper surface of the float 96 separately.

  That is, the float 92 moves up and down (floats and sinks) depending on the level of the drainage in the drainage buffer 91 while the displacement prevention pin 97 is guided by the peripheral wall surface of the drainage hole 86. Therefore, when the inside of the drain buffer 91 is full, the float 96 floats and the drain hole 86 is blocked by the upper surface thereof, so that the drain does not overflow onto the leak receiving plate 62 and the water level in the drain buffer is increased. When it is low, the float 96 sinks and the drain hole 86 is opened, so that the drainage on the leak receiving plate 62 flows down from the drain hole 86 to the drain buffer 91. According to this, it is possible to prevent the drainage flowing back from the drainage opening 78 to the drainage buffer 91 from overflowing from the drainage hole 86 of the leakage receiving plate 62, and the drainage on the leakage receiving plate 62 is allowed to flow through the drainage hole 86. Thus, the water can be smoothly flowed down to the drain buffer 91.

  The lower frame 32 configured in this manner has the upper surfaces of the water leakage receiving plate 62, the lower seal mounting portion 72, the lower guide rail 71, and the inclined portion 67 disposed substantially flush with each other and located on both sides of the upper surface. The floor structure has almost no step between the waterproof pan 5 and the dressing room floor 6. Since the lower frame seal member 73 and the water return member 82 are made of an elastic material such as a resin that protrudes upward, it is unlikely that a person will trip over and feel uncomfortable on the soles of the feet. I don't feel any pain.

  On the other hand, as described above, the upper surface of the inclined portion 67 is slightly inclined toward the waterproof pan 5, and the lower seal mounting portion 72 and the lower guide rail 71 are partially cut off at both end portions in the finding direction. Alternatively, since it is opened, the upper surface of the inclined portion 67 (both ends in the finding direction) serves as a drainage channel that guides the drainage flowing down from the drainage hole 86 of the leak receiving plate 62 to the waterproof pan 5. That is, the drainage that has flowed down to the water leakage receiving plate 62 flows down the upper surface of the inclined portion 67 through the drainage opening 78 of the lower seal mounting portion 72 and the cutout portion of the lower guide rail 71, and is guided to the waterproof pan 5.

  Here, the function of the water stop structure of the embodiment will be described. The bathroom drainage flows from the washing area to the lower frame 32 when the drainage trap outside the figure provided in the bathroom cannot be swallowed. First, the downward seal member 56 (primary water stop line) that is in close contact with the lower guide rail 71 is used. ) And the waste water that enters the dressing room B beyond the downward seal member 56 is stopped by the lower frame seal member 73 (secondary water stop line) that is in close contact with the protruding piece 57 of the lower collar 12. The Further, even if the wastewater enters the dressing room B side beyond the lower frame seal member 73, the wastewater flows on the leak receiving plate 62 and flows down from the drainage hole 86 to the drainage buffer 91. The drainage flowing down to the drainage buffer 91 flows toward the waterproof pan 5 on the upper surface of the inclined portion 67 slightly inclined toward the bathroom A side. Even if the amount of drainage leaked from the lower frame seal member 73 temporarily increases more than the amount of drainage flowing down from the drain hole 86 to the drain buffer 91, the drainage is blocked by the water return member 82 and the dressing room. There is no leakage to the B side.

Further, since the waste water flowing backward from the drain opening 78 of the lower seal mounting portion 72 is temporarily stored in the drain buffer 91 and pressed by the leak receiving plate 62, the drain is prevented from overflowing from the drain hole 86 of the leak receiving plate 62. And it does not leak to the dressing room B side. Further, even if the drainage water temporarily accumulated in the drainage buffer 91 becomes full and leaks from the junction between the drainage hole 86 or the water leakage receiving plate 62 and the lower seal mounting portion 72 or the water return mounting portion 81, The return member 82 prevents water leakage to the dressing room floor 6. The waste water that overflows from the drain buffer 91 and accumulates on the leak receiving plate 62 also decreases the water level in the drain buffer 91 as the bathroom waste water drains from the drain trap and decreases over time. As time passes, the water is led from the drain hole 86 to the bathroom.
On the other hand, by providing the water leakage receiving plate 62 and the drain buffer 91 in this way, it is possible to earn a time lag until the reduced water state on the bathroom A side is started. The water pressure on the lower frame seal member 73 (secondary water stop line) due to the drainage water that enters the water can be released, and the drainage is less likely to leak to the dressing room B side beyond the lower frame seal member 73.

  Therefore, according to the water stop structure of the bathroom fitting of this embodiment, the drainage leaked from the secondary water stop line constituted by the lower frame seal member 73 to the dressing room B side can be smoothly guided to the bathroom A side. In addition, it is possible to effectively prevent the drainage of the bathroom A flowing back to the dressing room floor 6 from flowing backward.

  Subsequently, a modification of the first embodiment will be described. As shown in the enlarged view of FIG. 9, the structure of the lower body 12 of each door body 3a, 3b and the lower frame 32 of the folding door frame 2 according to the modification is the same as that of the first embodiment. Between the inclined portion 67 of 61 and the lower frame parting piece 68 that holds the dressing room floor 6, an upside down “L” shape projecting on the bathroom A side instead of the water return mounting portion rising from the inclined portion 67. A rising portion 77 having a plate fitting piece 77a is formed. The water leakage receiving plate 62 having the same configuration as that of the first embodiment is fitted between the lower seal mounting portion 72 and the plate fitting piece 77a so that the upper surface (the upper surface of the plate main body 62a) is The lower frame parting piece 68 is detachably mounted at a position slightly lower than the upper surface. That is, in the mounted state, the short hanging piece 62b of the water leakage receiving plate 62 is supported by the support piece 72b of the lower seal mounting portion 72 and its side surface is in close contact with the back surface of the lower seal mounting portion 72, and the long hanging piece 62b. Is supported by the inclined portion 67 and its side surface is in close contact with the side surface of the plate fitting piece 77a. In addition, it is preferable that the upper surface of the water leakage receiving plate 62 is flush with the upper surface of the plate fitting piece 77a or is disposed at a slightly lower position.

  Therefore, unlike the first embodiment, the water return member 82 is not mounted between the water leakage receiving plate 62 and the dressing room floor 6, but the upper surface of the lower frame parting piece 68 is higher than the upper surface of the water leakage receiving plate 62. Because of the position, the plate fitting piece 77a is connected at the portion connecting the upper surface of the dressing chamber B side end surface of the water leakage receiving plate 62 and the bathroom A side end upper surface of the lower frame parting piece 68 in the height direction, that is, at the rising portion 77.
