Description

  The present invention relates to a bathroom door fitting. Specifically, it relates to a bathroom entrance fitting (sash) for barrier-free.

As a bathroom fixture (sash), the floor level on the bathroom room side (dressing room side), the upper surface of the lower frame of the fixture, and the bathroom floor (washing area) is almost flat (flat). ) Barrier-free type joinery with a smooth surface is known.
In order to prevent water from flowing out from the washroom to the dressing room side, water barriers and drainage pipes have conventionally been installed as barrier-free type bathroom entrance / exit fixtures below the lower frame of the bathroom entrance / exit fixture. A structure that drains water flowing out of the bathroom by dropping it into a drainage basin below the lower frame has been used.

On the other hand, in this conventional structure, a space for disposing drainage pipes and water distribution pipes is required under the joinery and under the washroom, and workability and maintainability are reduced. Bathroom fittings have also been proposed (see, for example, Patent Document 1).
In patent document 1, while providing an upright part at the dressing room side edge part of the lower frame of the bathroom entrance / exit fitting, the sealing material which closes the clearance gap between this upright part and a door (shoji) is arranged, and it is a dressing room from a washing place. The outflow of water to the side was prevented by the upright part and the sealing material.

At this time, by providing the rising portion, the height level of the upper surface of the joinery and the floor surface of the dressing room can be made substantially the same, but, for example, 10-15 mm between the bathroom washing place and the upper surface of the joinery. There was a level difference. For this reason, in the said patent document 1, the attachment attachment piece which continues in the longitudinal direction is integrally formed in the lower frame manufactured by extrusion molding, the attachment which has an inclined surface is attached to this attachment piece, and a slope is attached to a level | step-difference part. By providing this, the bathroom entrance / exit part can be moved smoothly even in a wheelchair.
The low level drainage-less structure of the bathroom entrance / exit in which the drainage basin etc. below the lower frame is not required as in Patent Document 1 has the advantage that the drainage basin etc. can be eliminated and the workability and maintainability can be improved. In recent years, its adoption has been desired.

Japanese Patent Laying-Open No. 2003-221973 (FIG. 1)

However, in the low-level drainage-less structure of Patent Document 1, when removing the attachment and cleaning the upper surface of the lower frame, the attachment attachment piece protrudes from the upper surface of the lower frame, so that the cleaning workability of the portion is poor. There was a problem.
In addition, since the upper surface of the lower frame of the joinery is provided with a water gradient to return rainwater that has flowed over the attachment to the upper surface of the lower frame and returns to the bathroom side, water flows through a part of the attachment mounting piece. It was necessary to do so. Since the cutout portion of this attachment mounting piece is cut, it becomes rougher than the other upper surface of the lower frame, so that the drainage water does not flow smoothly, the drainage performance is reduced, or the water remains. There was also a problem that a residual water problem occurred.

  An object of the present invention is to provide a bathroom doorway fitting that can improve cleanability and drainage, and can reduce the problem of residual water.

A bathroom doorway fitting of the present invention is configured to include a joinery frame attached to a bathroom doorway and a door that can be opened and closed with respect to the joinery frame, and the lower frame of the joinery frame has a substantially flat upper surface. And an upright portion formed by rising upward from the end portion on the dressing room side of the upper surface portion, at least one attachment mounting member is attached to the upper surface portion, and the upper end of the attachment mounting member is A slope attachment having an inclined surface which is located at substantially the same height as the upper end of the upright portion and becomes lower toward the bathroom side is engaged and attached, and an upper surface portion is provided between the attachment for the slope and the upper surface portion of the lower frame. drainage space to return the water flowing out above the bath side is formed, the attachment mounting member portion contacting at least the slope for attachment made of resin The attachment for slope includes a metal attachment main body having an engaging portion that engages with the attachment mounting member and the inclined surface, and an end portion on the side of the undressing chamber that is fixed to the attachment main body and is undressed from the attachment main body. And a resin engaging member protruding to the chamber side, and an engagement recess is formed on the lower frame of the joinery frame to engage the undressing chamber side end of the engaging member. It is characterized by being.

In the present invention, the substantially flat surface means a flat surface in which protruding portions such as the attachment mounting piece of Patent Document 1 are not integrally formed. Furthermore, the substantially flat surface is not limited to a horizontal surface, but includes an inclined surface with a water gradient or the like.
According to the present invention as described above, for example, water that has flowed over the slope attachment to the upper surface of the lower frame is blocked by the upper portion of the lower frame and the sealing material, and is prevented from flowing out to the dressing room side. And the water which flowed out to the upper surface of the lower frame is returned to the bathroom washing area side through a drainage space formed between the attachment and the upper surface of the lower frame and discharged.
At this time, in the present invention, the upper surface portion of the lower frame is a substantially flat surface, and the attachment mounting piece as in Patent Document 1 is not formed, so that it is easy to clean when the slope attachment is removed. It can be carried out.

Further, only the attachment mounting member protrudes from the upper surface portion of the lower frame, and there is no mounting piece continuous in the longitudinal direction of the lower frame as in Patent Document 1, so that the protruding portion becomes an obstacle to drainage in the drainage space. The drainage performance can be improved. In addition, since the attachment attachment member separate from the lower frame is attached, the upper surface portion of the lower frame can be formed on a very smooth surface as compared with the notch portion of the attachment piece of Patent Document 1. For this reason, the water flowing through the upper surface of the lower frame flows very smoothly, the drainage performance can be improved, and the remaining water can also be greatly reduced as compared with Patent Document 1.
In addition, what is necessary is just to set the number of attachment attachment members and its space | interval mainly according to the dimension (width dimension of joinery) of the longitudinal direction of a lower frame. For example, when the width of the joinery is relatively small, such as folding doors, sliding doors, hinged doors, etc., the attachment mounting member is only at one location in the middle of the lower frame longitudinal direction and at two locations near the lower frame ends. If the width of the joinery is relatively large, such as a sliding door with 2 to 3 doors, the attachment mounting members are not only at two locations near both ends of the lower frame, but at a predetermined interval between them. What is necessary is just to attach in one to several places distant. When the attachment attachment member is attached to one location in the approximate center of the lower frame longitudinal direction, both ends of the slope attachment need only be supported by the lower frame or vertical frame, which stabilizes the attachment state of the attachment. Can be made.

Here, the attachment mounting member, Ru partial least slope attachment abuts the der resin.
The attachment for slope is usually made of a metal material with excellent water resistance such as aluminum alloy and stainless steel so that it will not change even when exposed to water for a long time and can support the load even if the user gets on it. . Here, the same metal material can be used for the attachment mounting member, but in this case, when the user moves on the attachment for the slope, the metal material of the attachment and the mounting member comes into contact with each other and makes a sound. Will occur.
On the other hand, since the portion of the attachment mounting member that contacts the attachment is made of resin , the contact portion between the metal materials can be eliminated, and the generation of noise can be prevented.
In addition, what is necessary is just to fix an attachment attachment member to the bathroom side upper surface of a lower frame with a screw | thread or an adhesive agent.

Runode slope attachment is provided with a engaging member made of a resin, it can be fixed slope attachment at two locations of the lower frame expected direction of the attachment mounting member and the engaging recess (direction toward the changing room from the bathroom), a slope The attachment can be stably attached to the lower frame.
In addition, since the engaging member is made of resin, it is possible to prevent the noise from being generated even if it comes into contact with the metal lower frame.

The slope attachment comprises a rail for guiding the door and the inclined surface, and the height levels of the upper end of the rail, the upper end of the inclined surface, and the upper end of the end of the dressing room are substantially the same. It is preferable.
If a rail is formed on the attachment, there is no need to form a rail on the lower frame of the joinery, so both the lower frame for sliding doors and folding doors that require rails and the lower frame for hinged doors that do not require rails are used. You can also.

Further, a bathroom doorway fitting according to the present invention is a bathroom doorway fitting configured to include a joinery frame attached to the bathroom doorway and a door that can be opened and closed with respect to the joinery frame. The lower frame of the frame includes an upper surface portion and an upright portion formed by rising upward from an end portion on the dressing room side of the upper surface portion, and the upper surface portion is formed to have a water gradient descending to the bathroom side. At least one attachment attachment member is attached to the upper surface portion, and the attachment attachment member has a slope having an inclined surface whose upper end is positioned substantially at the same height as the upper end upper end and becomes lower toward the bathroom side. A drainage space is formed between the attachment for the slope and the upper surface of the lower frame to return the water that has flowed out onto the upper surface to the bathroom side. A drain outlet cover member is attached to the end of the touchment, and an opening is formed between the bathroom side end of the drain outlet cover member and the upper surface of the washroom in the bathroom. A configuration may be adopted in which water is drained to the upper surface of the washing area through the opening.
And the bathroom side end of the attachment for slope extends to the upper surface of the bathroom washing area, and the bathroom side end of the attachment for slope and the upper surface of the washing area abuts directly or via a sealing material. May be.
If the bathroom side end of the slope attachment extends to the upper surface of the bathroom washroom, the joint surface between the lower frame of the joinery and the bathroom floor can be covered with the attachment, improving design and waterproofing. .

Moreover, it is preferable that the sealing material which closes between the standing upper part of the said lower frame and the lower surface of a door is provided.
The water that flows into the upper surface of the lower frame is blocked by the upper part of the lower frame, but if a sealing material is provided between the upper part and the lower surface of the door, the water overflows to the dressing room side. This can be prevented more reliably. For this reason, the height dimension of the upright part, that is, the level difference between the floor surface of the bathroom and the floor surface of the dressing room can be suppressed to about 10 to 15 mm or less, and the bathroom for barrier-free can be easily attached by attaching the attachment for slope. It can be an entrance.

Further, a bathroom doorway fitting according to the present invention is a bathroom doorway fitting configured to include a joinery frame attached to the bathroom doorway and a door that can be opened and closed with respect to the joinery frame. The lower frame of the frame includes a substantially flat upper surface portion and an upright portion formed by rising upward from an end portion on the dressing room side of the upper surface portion, and at least one attachment mounting member is attached to the upper surface portion. The attachment attachment member is engaged with and attached to a slope attachment having an inclined surface whose upper end is located at substantially the same height as the upper end upper end and becomes lower toward the bathroom side, and the attachment for the slope and the drainage space for returning the water flowing out onto the upper surface in the bathroom side is formed between the upper surface of the lower frame, bathroom side end portion of the slope for attachment, washing bath A water pulling member straddling the drainage space and the upper space of the bathroom washroom is in contact with the upper surface of the lower frame or between the upper surface and the lower surface of the attachment for the slope. The water pulling member may be provided with a surface area expanding means for increasing the surface area relative to the projected area .
Here, the predetermined gap between the water-drawing member and the lower frame upper surface portion may be equal to or less than the height dimension (for example, about 3 mm) of water that tends to stay in the lower frame upper surface portion due to surface tension.
According to such a configuration, even if water is about to stay on the upper surface of the lower frame formed in a flat shape, the surface tension of the water is broken by the water pulling member that is in contact with the surface of the water, and the water on the upper surface of the lower frame is It can be pulled (guided) along the water-drawing member to the bathroom washroom side, and the remaining water can be further reduced.

At this time, the in drawing water member, that provided the surface area enlarging means for increasing the surface area with respect to the projection area.
Here, the surface area enlarging means may be constituted by holes, irregularities, grooves or the like formed in the water-drawing member itself, or may be constituted by a porous material such as a sponge attached to the surface of the water-drawing member.
According to such a configuration, since the surface area of the water pulling member is increased, the surface tension of the water that tends to stay on the upper surface of the lower frame can be easily broken, and this water can be guided more reliably.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
In the second and subsequent embodiments, the same constituent members as those described in the first embodiment and the constituent members having the same functions are denoted by the same reference numerals as those in the first embodiment. Those descriptions are omitted or simplified. Moreover, in each figure, in order to make a drawing legible, about the main structural member, the hatching of the cross-sectional part may be abbreviate | omitted.

[First Embodiment]
A bathroom door fitting (sash) according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 4.

FIG. 2 is a longitudinal sectional view of the bathroom doorway fitting 1, and FIG. 3 is a transverse cross-sectional view of the bathroom doorway fitting 1. FIG. 4 is an enlarged longitudinal sectional view showing a lower frame portion that is a main part of the bathroom doorway fitting 1. FIG. 5 is a longitudinal sectional view showing a state before the attachment of the slope attachment 30 in the bathroom doorway fitting 1. FIG. 6 is a perspective view showing an end of the slope attachment 30.

The bathroom entrance / exit of this embodiment consists of the floor surface (upper surface) 2A of the bathroom floor (washing area) 2, the floor surface (upper surface) 3A of the dressing room floor 3, and the uppermost surface of the sill of the joinery frame 10 (lower frame 12). It is a low step structure with a step of about 10 to 15 mm or less.
In this bathroom, the bathtub (not shown), the bathroom floor (waterproof pan) 2 and the like are integrally formed from FRP (Fiber-Reinforced Plastics) or the like, or unitized by combining separately manufactured members. It is placed on a housing (not shown).

The bathroom doorway fitting 1 is a door opening type door including a door frame 10 and a sliding door type shoji (movable door, door, door) 20 provided in the door frame 10 so as to be freely opened and closed.
The joinery frame 10 is formed by a four-round frame of an upper frame 11, a lower frame 12, and left and right vertical frames 13 made of an aluminum extruded profile. Then, on the dressing room side, the lower frame 12 is fixed to the dressing room floor 3 and the upper frame 11 is fixed to the ceiling 4 with screws, and on the bathroom side, the support frame 2B formed at the end of the bathroom floor 2 is The frame 12 is placed and supported. At this time, the gap between the bathroom side surface of the lower frame 12 and the bathroom floor 2 is filled with a wet sealant 5 and sealed.
Since the structures of the upper frame 11 and the vertical frame 13 and the mounting structure on the housing side are the same as those in the prior art, the description is omitted except for the lower frame 12 which is a characteristic part of the present embodiment.

  The shoji 20 is formed by incorporating an upper extrusion 21 made of an aluminum extruded shape member, a lower eaves 22 and left and right eaves 23, and incorporating a face material 24 such as glass or resin. The shoji 20 is rotatably supported by the joinery frame 10 at one of the reeds 23, and has the same configuration as a general single swing door. Therefore, the lower reed 22 is a characteristic part of this embodiment. Description is omitted except for.

As shown in FIG. 4, the lower frame 12 is a substantially hollow cylindrical extruded product, and includes a substantially horizontal upper surface portion 121, and an upright portion 122 that rises substantially vertically from the edge of the upper surface portion 121 on the dressing room side. And a covering portion 123 extending from the upright portion 122 to the dressing room side.
Screw holes 124 used for joining the vertical frame 13 are formed on the lower surface of the upper surface portion 121, that is, the inner surface of the lower frame hollow portion and the lower surface of the upright portion 122 (surface on the dressing room side).

In addition, a pocket portion 126 that holds a sealing material 125 for enhancing waterproofness is formed at a joint portion between the upright portion 122 and the covering portion 123.
Further, on the side surface of the upright portion 122 on the bathroom side, an engagement concave groove (engagement concave portion) 127 into which a slope attachment 30 described later is engaged is formed continuously in the longitudinal direction of the lower frame 12.

  Here, although the upper surface part 121 is made into the substantially flat horizontal surface, it is slightly inclined so that it may become low toward the bathroom side end surface from the standing part 122, and the water gradient is given. More specifically, the upper surface portion 121 is located on the bathroom side of the dressing room side upper surface portion 121A and the undressing room side upper surface portion 121A located on the lower surface of the shoji 20 in the closed position due to the difference in the angle of the water gradient. It is divided into three regions: a continuous intermediate upper surface portion 121B and a bathroom end side upper surface portion 121C continuous to the bathroom side of the intermediate upper surface portion 121B. And the gradient (inclination angle) of the dressing room side upper surface portion 121A and the bathroom end side upper surface portion 121C is set to a substantially horizontal angle, and the gradient (inclination angle) of the intermediate upper surface portion 121B is made larger than these angles. ing.

  Two grooves 128 continuous in the longitudinal direction of the lower frame 12 are formed on the upper surface of the bathroom end side upper surface portion 121 </ b> C over substantially the entire length in the longitudinal direction of the lower frame 12. The groove 128 has a predetermined depth dimension (for example, 0.3 to 0.6 mm), is formed in a substantially semicircular cross section or a substantially triangular cross section, and allows water on the bathroom end side upper surface portion 121C to flow. It can be guided along the groove 128. That is, the surface tension of the water which is going to stay on the bathroom end side upper surface part 121C is broken by the groove 128, so that the water is less likely to stay on the bathroom end side upper surface part 121C and is smoothly discharged. It is configured.

As shown in FIG. 3, attachment attachment members 40 are attached by screws 41 at two locations near the left and right ends of the lower frame 12, more specifically at two locations near the left and right ends of the bathroom end side upper surface portion 121 </ b> C. It is fixed.
As shown in FIGS. 5 and 6, the attachment mounting member 40 stands from a rectangular plate-like base portion 42 placed on the bathroom end side upper surface portion 121 </ b> C and a side of the base portion 42 on the dressing room side. The engaging wall portion 43 is provided, and left and right wall portions 44 continuous to the engaging wall portion 43 are provided.

Two protrusions 42 </ b> A that engage with the grooves 128 are formed on the lower surface of the base portion 42. For this reason, even if the attachment mounting member 40 is fixed with the single screw 41, the attachment mounting member 40 can be prevented from rotating by engaging the protrusion 42A with the groove 128, and the attachment mounting member 40 Screw fixing work can be easily performed.
Note that the head of the screw 41 is configured to fit in a recess surrounded by the engaging wall 43 and the wall 44 so as not to protrude above the attachment mounting member 40.

  The upper surface of the wall portion 44 is inclined so that the inclined surface of the slope attachment 30 can be supported. Further, the engaging wall 43 is formed with an engaging protrusion 43 </ b> A with which the slope attachment 30 is engaged.

The slope attachment 30 includes a metal attachment main body 31 such as an aluminum alloy and a resin engagement member 35 fixed to the attachment main body 31.
The attachment main body 31 includes a horizontal surface portion 32 and an inclined surface portion 33 formed continuously on the bathroom side of the horizontal surface portion 32. Two engaging protrusions 321 having an L-shaped cross section projecting in opposite directions are integrally formed on the lower surface of the horizontal surface portion 32, and the engaging member 35 is engaged and fixed to the engaging protrusion 321. ing.
An engagement protrusion 331 that engages with the engagement wall 43 of the attachment mounting member 40 is integrally formed on the lower surface of the inclined surface portion 33. In addition, a vertical wall portion 332 formed by being bent vertically downward and a folded portion 333 formed by folding the vertical wall portion 332 toward the dressing room are provided at the bathroom side edge of the inclined surface portion 33. It has been.

On the other hand, the engagement member 35 is a short piece (piece) in which an engagement portion 36 engaged with the engagement protrusion 321 and an engagement protrusion 37 engaged with the engagement groove 127 are integrally formed. Member). Two engaging members 35 are provided in total, at least one in the vicinity of both ends of the slope attachment 30. Depending on the length of the slope attachment 30, one to several engagement members 35 are further provided in the intermediate portion.
And when the attachment 30 for slopes is attached to the lower frame 12, the engaging member 35 is mounted in the dressing room side upper surface part 121A, and the folding | returning part 333 is mounted in the floor surface 2A of the bathroom floor 2, and is metal. The attachment main body 31 is configured so as not to directly contact the metal lower frame 12.

The height level of the horizontal surface portion 32 of the attachment for slope 30 is the same as that of the upper surface of the covering portion 123 of the lower frame 12, and is therefore substantially the same as the floor surface 3 </ b> A of the dressing room floor 3.
On the other hand, the floor surface 2A of the bathroom floor 2 and the height level of the horizontal plane portion 32 are different by about 10 to 15 mm, and a step is provided. In addition, the height of the vertical wall portion 332 is 5 mm or less, the slope of the inclined surface portion 33 is 1/5 (11 degrees) or less, and the depth of the inclined surface portion 33 is within 40 mm. The gradient is 1/8 (about 7 degrees or less).

  A seal member 220 is attached to the lower surface of the lower collar 22. The seal member 220 is fitted to the lower heel 22, and seal pieces 221 and 222 project downward from the bathroom side edge and the dressing room side edge, respectively. The seal piece 221 formed on the bathroom side edge is in contact with the attachment main body 31 and is primarily waterproofed so that the water on the bathroom side does not flow out beyond the attachment 30 for the slope. Further, the seal piece 222 formed on the edge of the dressing room is in contact with the sealing material 125, and is secondarily waterproofed so that the water flowing over the seal piece 221 does not flow out to the dressing room side. .

As shown in FIGS. 3 and 6, drain outlet cover members 50 are attached to the left and right ends of the slope attachment 30. The drain port cover member 50 includes two insertion portions 51 and 52, and the insertion portion 51 is inserted between the vertical wall portion 332 and the engagement protrusion 331, and the insertion portion 52 is inserted between the two engagement protrusions 321. By doing so, it attaches to the attachment 30 for slopes so that attachment or detachment is possible.
The drain port cover member 50 includes an inclined surface portion 53 that is flush with the inclined surface portion 33 and a horizontal surface portion 54 that is flush with the horizontal surface portion 32.
However, portions corresponding to the vertical wall portion 332 and the folded portion 333 are not formed in the drain port cover member 50, and an opening 55 is formed between the bathroom side end surface of the drain port cover member 50 and the floor surface 2A. Has been.

Next, the drainage structure in the bathroom doorway fitting 1 will be described.
Normally, water that has flowed into the slope attachment 30 portion from the bathroom floor 2 is blocked by the seal piece 221 that contacts the slope attachment 30 and returned to the bathroom side through the inclined surface portion 33. In addition, when there is a lot of water flowing into the slope attachment 30 or when it flows in vigorously, a part of the flowing water may get over the seal piece 221. In this case, the horizontal surface portion 32 is undressed. Water flows down from the chamber side end surface to the upper surface portion 121.

The water that has flowed down to the upper surface portion 121 is blocked by the upright portion 122 and further blocked by the sealing materials 125 and 222, and therefore does not flow out to the covering portion 123 side, that is, the floor surface 3A of the dressing room. For this reason, the water which flowed into the upper surface part 121 flows on the upper surface part 121 to the bathroom side according to the water gradient. Here, since the bathroom side end portion of the slope attachment 30 is blocked by the vertical wall portion 332, water flows in the left-right direction (longitudinal direction of the lower frame 12) on the bathroom end side upper surface portion 121C.
The water that flows in the left-right direction on the bathroom end side upper surface 121C reaches the left and right drain cover members 50 and is returned to the floor 2A from the opening 55.
Accordingly, the drainage space 60 is formed by the space defined between the attachment mounting member 40 and the upper surface portion 121.

According to this embodiment, there are the following effects.
(1) When attaching the slope attachment 30 to the lower frame 12, the attachment attachment member 40 is fixed to the upper surface portion 121, and the slope attachment 30 is engaged and attached to the attachment attachment member 40. For this reason, compared with the lower frame in which the attachment mounting pieces as in Patent Document 1 are integrally formed over substantially the entire length of the lower frame, the small attachment mounting members 40 are mounted on the upper surface portion 121 in only two places. Therefore, the upper surface portion 121 can be formed on a substantially flat surface. For this reason, when the attachment 30 for slopes is removed from the lower frame 12, the upper surface part 121 part can be cleaned easily.

(2) Only the attachment attachment member 40 protrudes from the upper surface portion 121 of the lower frame 12, and there is no attachment piece continuous in the longitudinal direction of the lower frame as in Patent Document 1, so The number of protruding protrusions can be reduced, and drainage performance can be improved.
In addition, since the attachment attachment member 40 that is a separate body from the lower frame 12 is attached, the upper surface portion 121 can be formed on a very smooth surface compared to the case where the attachment pieces are notched. For this reason, the water which flows through the upper surface part 121 flows very smoothly, drainage can be improved, and the remaining water of the upper surface part 121 can also be reduced very much. For this reason, the upper surface part 121 of the lower frame 12 can be dried immediately, and cleanliness can be maintained.

  (3) Since the groove 128 is formed in the bathroom end side upper surface portion 121C, the surface tension of the water flowing into the bathroom edge side upper surface portion 121C is broken, and water is supplied to the end position of the lower frame 12 along the groove 128. It can guide and can drain from the opening 55 of the drain outlet cover member 50. For this reason, the water on the upper surface part 121 can be effectively drained over the entire length of the lower frame 12.

  (4) Since the attachment for slope 30 is configured using an attachment body 31 made of a metal such as an aluminum alloy, the slope attachment 30 is excellent in water resistance and rigidity and can be made relatively lightweight. It can be handled easily.

  (5) Since the attachment mounting member 40 is made of synthetic resin and the portion of the slope attachment 30 that contacts the metal lower frame 12 is formed of the resin engaging member 35, the metal attachment main body 31 is directly made of metal. It can prevent contacting with the made lower frame 12. For this reason, when the user steps on the attachment 30 for the slope, it is possible to prevent the generation of sound due to contact between the metal materials, and to prevent the user from feeling uncomfortable.

  (6) Since the attachment for slope 30 is attached by engaging the engagement protrusion 331 and the engagement protrusion 37 in the attachment groove 40 of the attachment attachment member 40 and the lower frame 12, the attachment 30 for slope is attached. Can be fixed at two places in the expected direction (direction from the bathroom toward the dressing room), and the attachment for slope 30 can be stably attached to the lower frame 12. Further, since the slope attachment 30 is simply engaged and fixed to the lower frame 12 side, the attachment / detachment work of the slope attachment 30 can be performed very easily compared to the case of screwing or the like. Moreover, the workability | operativity of the cleaning work performed by removing the attachment 30 for slopes can also be improved.

(7) Since the bathroom side end of the slope attachment 30 extends to the bathroom floor 2A, the attachment surface of the lower frame 12 and the bathroom floor 2, that is, the portion filled with the sealing agent 5 is attached to the attachment 30. It can coat | cover and can improve the designability and waterproofness.
Furthermore, since the bathroom floor 2 is made of FRP or the like, even if the metal attachment main body 31 is directly placed, it is possible to prevent the noise caused by the contact.

(8) Since the space between the raised portion 122 of the lower frame 12 and the lower collar 22 is closed with the sealing materials 125 and 222, even if the water that has flowed onto the upper surface portion 121 exceeds the raised portion 122, the water Can be reliably dammed by the sealing materials 125 and 222, and the waterproof performance can be improved.
In addition, by providing the sealing materials 125 and 222, it is not necessary to increase the height of the upright portion 122 so much, and the height of the upright portion 122, that is, the floor surface 2A of the bathroom and the floor surface 3A of the dressing room The step size can be suppressed to about 10 to 15 mm or less, and by attaching the attachment 30 for the slope, it can be easily used as a bathroom entrance corresponding to barrier-free.

[Second Embodiment]
Next, a bathroom fitting 1A according to a second embodiment of the present invention will be described with reference to FIG.
The bathroom doorway fitting 1A is a folding door type fitting, and a rail 131 for guiding a shoji (door) 20 is integrally formed on the lower frame 12. For this reason, the engagement concave groove 127 with which the engagement projection 37 of the slope attachment 30A is engaged is formed not at the upright portion 122 but at the base portion of the rail 131.
Further, the lower rod 22 is provided with a sealing material 223 that abuts on the rail 131, and temporarily stops the water flowing out beyond the attachment 30 for the slope.
