[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing floor of a bathroom unit, and more particularly to a structure of a washing floor suitable for a barrier-free bathroom unit.

[0002]

2. Description of the Related Art When building a bathroom in a house or the like,
A so-called unit bathroom (hereinafter, referred to as a “bathroom unit”) is often installed at a predetermined position in a building frame. In general, bathroom units
There is provided a floor pan comprising a washing floor, which constitutes a floor portion of the washing room, and a bathtub installation section for installing a bathtub. And wall panels are erected around the floor pan,
A ceiling is placed on the upper end of the wall panel. The entrance of the bathroom unit is selectively set depending on the design items such as the arrangement of the undressing room.

[0003] In recent years, a so-called barrier-free type bathroom unit has been proposed as a bathroom unit that allows a person with a physical disability to easily enter and exit. In the bathroom unit of the barrier-free type, the floor of the dressing room and the entrance of the bathroom unit should not be stuck when a person with a physical disability enters or exits the bathroom unit through the entrance. The lower edge and the upper surface of the bathroom floor are set at almost the same height. In this case, appropriate drainage means are provided on the lower edge of the entrance so that water overflowing from the bathtub or water used in the washing place does not flow out to the dressing room through the entrance.

FIG. 6 is a view for explaining a water gradient of a conventional typical washing floor in a barrier-free type bathroom unit. In the rectangular washing floor 91 shown in FIG. 6, three sides 9A except for the side 91A facing the bathtub (not shown).
The three sides 91B so that the entrance can be selectively set along any one of the sides 91B to 91D.
The height positions of 同 じ 91D are the same. In addition, a rectangular drain port (actually, only the drain port lid is shown in FIG. 6) 92 is provided near the center of the side 91A facing the bathtub. The washing floor 91 has one corner 92 a of a rectangular drain port 92 and the washing floor 91.
And three regions 94a defined by a boundary 93a connecting the one corner 91a of the washing room 91 and the other corner 92b of the drain outlet 92 and the other corner 91b of the washing floor 91. , 94b and 94c.

[0005] A central region 94a defined by a pair of boundary lines 93a and 93b is formed in a plane shape provided with a water gradient as indicated by a rightward arrow 95a in the figure. Further, a triangular region 94b defined by the boundary 93a and the side 91C is formed in a plane shape with a water gradient as shown by an arrow 95b pointing right lower in the figure. Further, a triangular area 94c defined by the boundary line 93b and the side 91D is formed in a plane shape provided with a water gradient as shown by an arrow 95c pointing upward in the figure. as a result,
The water overflowing from the bathtub and the water used in the washing place are guided to the drain outlet 92 along arrows 95a to 95c.

[0006]

As described above, the conventional washing floor shown in FIG. 6 is composed of three large planar areas having gradients along different directions. As a result, when a chair is used in a washing room, the legs of the chair are likely to be installed over two regions having different inclination directions unless special care is taken, and the chair is unstable and unstable. It should be noted that the conventional washing floor is not necessarily composed of three large planar regions, and for example, there is an example in which the floor is entirely formed in a mortar shape. However, the point that the planar area occupying at least a large part of the center of the washing floor is not sufficiently secured is common to the conventional washing floor, and as a result, the inconvenience that the chair is unstable and unstable is also present. Common to floors.

The present invention has been made in view of the above-mentioned problems, and has as its object to provide a washing floor which is suitable for, for example, a bathroom unit of a barrier-free type and in which a chair can always be used in a stable state. And

[0008]

According to the present invention, there is provided, in accordance with the present invention, a drain port formed near a side facing a bathtub on a rectangular washing floor of a bathroom unit; A substantially horizontal horizontal peripheral portion formed in a band shape of a predetermined width along the other three sides except the facing side, and toward the drain port along a pair of opposing sides of the three sides; A central superelevation having a constant superelevation;

According to a preferred aspect of the present invention, water formed into a narrow band along the side facing the bathtub and flowing into the drain port through the central one-side slope portion or the pair of connection slope portions is supplied to the drain port. It is preferable to have a drain for guiding.
In this case, the drain port is formed near the center of the side facing the bathtub, the drain grooves are formed on both sides of the drain port, and each drain groove corresponds to one of the pair of connection gradient parts. It is preferable that the connecting portion is inclined toward the drain port.

According to a preferred aspect of the present invention, the horizontal peripheral portion is set at substantially the same height as a lower end edge of an entrance of the bathroom unit, and water flows out of the bathroom unit through the entrance. It is preferable that a drain pit for preventing the drainage is provided facing the lower edge of the entrance. In this case, it is preferable that the drain pit is attached so as to contact the upper surface of the horizontal peripheral portion.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS On the washroom floor of a bathroom unit according to the present invention, a drain port is formed in the vicinity of the side facing the bathtub, and a horizontal periphery is formed along three other sides except the side facing the bathtub. The part is formed in a band shape having a predetermined width. In addition, 3
A central oblique portion having a constant oblique angle toward the drain is formed along a pair of opposing sides of the two sides, and between the horizontal peripheral portion and the central oblique portion along the pair of sides. Is formed with a pair of connection gradient portions formed in an elongated strip shape.

As described above, in the washing floor of the present invention, a region excluding the horizontal peripheral portion formed in a band shape having a predetermined width and a pair of connecting gradient portions formed in an elongated band shape, that is, most of the washing floor is provided. In the occupied central region, a flat central inclined portion having a constant inclined angle is formed. In other words, in the present invention, in the center of the washing floor,
A planar area occupying most of the area is sufficiently ensured. As a result, the legs of the installed chair do not protrude from the central sloping part without any special attention,
The chair can always be used in a stable state.

[0014] Further, by forming the drainage groove in a narrow band along the side facing the bathtub, the effective area of the central single-slope portion occupying most of the center of the washing floor can be reduced without substantially reducing the effective area. The water flowing into the drain can be reliably guided to the drain through the one-sided slope or the pair of connection slopes. In this case, a drain port is formed near the center of the side facing the bathtub, and a pair of drain grooves are formed on both sides of the drain port. By forming each drain so as to incline,
Even if the height position of the bottom of the drain is not set so low, the water gradient of each drain can be sufficiently ensured.

Further, the upper surface of the horizontal peripheral portion is set at substantially the same height as the lower edge of the entrance of the bathroom unit, and a drain pit for preventing water from flowing out of the bathroom unit through the entrance is provided at the entrance. By providing the lower end edge, a barrier-free bathroom unit can be realized using the washing floor of the present invention. in this case,
By selectively utilizing any one of the horizontal perimeters similarly formed on the three sides for the installation of the drainage pit, any one of the other three sides except the side facing the bathtub is used. The entrance of the bathroom unit can be selectively set along one side.

In particular, by adopting a configuration in which the drain pit is attached so as to abut on a smooth upper surface having a high finishing accuracy in the horizontal peripheral portion, compared with a conventional example in which the drain pit is attached to the lower surface of the peripheral portion. In addition, a high-precision molding method is not required on both sides when manufacturing a washing floor. That is, when the washing floor is manufactured using a resin material such as FRP (glass fiber reinforced plastic), it is not always necessary to use a high-precision and high-cost molding method such as hot press molding, but hand lay-up molding. It is possible to use a relatively low-precision and low-cost molding method such as (manual molding).

An embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view schematically showing a main configuration of a washing floor according to an embodiment of the present invention. FIG.
FIG. 2 is a sectional view taken along line AA in FIG. 1. FIG. 3 is a top view of the washing floor of FIG. FIG.
In FIG. 3 to FIG. 3, illustration of a peripheral rising portion is omitted in order to clearly show a main configuration of the washing floor. In this embodiment, the washing floor of the present invention is applied to a barrier-free bathroom unit.

Referring to FIGS. 1 to 3, the washing floor 1 of the bathroom unit of the present embodiment has a rectangular planar shape. A drain port 2 is provided in the vicinity of the center of the side 1a facing the bathtub (not shown) among the four sides that define the periphery of the rectangular washing floor 1. The drain port 2 is a drainage pipe (not shown) for draining water overflowing from the bathtub or water used in the washing area.
A step portion 2a formed to receive the lid 2d of the drain port 2, a drain through hole 2b formed at the bottom of the step portion 2a, and a through hole 2b. And a drain pipe 2c (shown only in FIG. 2) attached to the bottom of the stepped portion 2a so as to be aligned.

Further, strip-shaped horizontal peripheral portions 3b to 3d having a predetermined width are formed along the three sides 1b to 1d except the side 1a facing the bathtub. Horizontal peripheral part 3b
3d have a substantially horizontal upper surface in a state where the washing floor 1 of this embodiment is positioned at a predetermined position. Note that the predetermined width of the horizontal peripheral portions 3b to 3d is a size defined based on the minimum size required to mount the drainage pit 42 described later. Hereinafter, when referring to the positional relationship of each part, unless otherwise stated, it is the positional relationship in the state where the washing floor 1 of this embodiment is positioned at a predetermined position.

Further, in the central area of the washing floor 1,
A horizontal peripheral part 3 formed along the side 1b facing the bathtub
A rectangular single-sided slope portion 4 having a constant single-sided slope descending from the bottom b to the drain port 2 is formed. More specifically, as shown by an arrow 4a along the pair of sides 1c and 1d facing each other among the three sides 1b to 1d except for the side 1a facing the bathtub, on the upper surface of the central single-inclined portion 4. A constant water gradient is provided.

An elongated strip extending along the pair of sides 1c and 1d is provided between the pair of horizontal peripheral portions 3c and 3d formed along the pair of sides 1c and 1d, respectively, and the central inclined portion 4. Are formed. The pair of connection gradient portions 5c and 5d are band-shaped regions for continuously connecting between the pair of horizontal peripheral portions 3c and 3d and the central single gradient portion 4, and the width dimension thereof is suppressed to some extent. I have. As described above, the widths of the horizontal peripheral portions 3b to 3d and the connection gradient portions 5c and 5c
Since the width of d is set to be equal to or less than a predetermined dimension, the central superelevated portion 4 constitutes a planar area occupying most of the center of the washing floor 1.

Further, the washing floor 1 of the present embodiment includes:
A pair of narrow strips (for example, extremely narrow strips having a width of about 50 mm) are formed on both sides of the drain port 2 along the side 1a facing the bathtub. Each drain groove 6a and 6b is provided with a suitable water gradient such that it descends from the corresponding connection gradient portion 5c and 5d toward the drain port 2 as shown by an arrow 6c. Therefore, the water that has flowed into the drain grooves 6a and 6b via the central one-side slope part 4 and the connection slope parts 5c and 5d is surely guided to the drain port 2.

FIG. 4 is a perspective view showing a state where a drain pit is attached to the horizontal peripheral portion of the washing floor of the present embodiment. Note that FIG. 4 shows a peripheral rising portion which is not shown in FIGS. 1 to 3. As shown in FIG. 4, a peripheral rising portion 41a is formed on the side of the washroom floor 1 facing the bathtub. The peripheral rising portion 41a is a portion formed integrally with the pair of drain grooves 6a and 6b, and is also formed integrally with a bathtub installation portion (not shown) as necessary.

The other three sides of the washing floor 1 except for the side facing the bathtub have peripheral rising portions 41b to 41b.
1d are respectively formed. Peripheral riser 41b ~
41d is a part integrally formed with the horizontal peripheral parts 3b to 3d, and is a part for supporting the lower end of the wall panel when the corresponding wall panel (not shown) is erected.

As described above, the entrance of the bathroom unit is selectively set depending on the design items such as the layout of the undressing room. In this embodiment, as an example, a case will be described in which the entrance of the bathroom unit is provided on the side facing the bathtub. The configuration of the horizontal peripheral portion and the peripheral rising portion is common to the other three sides except the side facing the bathtub, and in this embodiment, any one of the other three sides except the side facing the bathtub is used. Obviously, the entrance of the bathroom unit on one side can be provided selectively and in the same way.

As described above, in the bathroom unit of the barrier-free type, the undressing room is provided so that a physically handicapped person does not trip when entering or leaving the bathroom unit through the entrance. , The lower edge of the entrance of the bathroom unit and the upper surface of the washroom floor 1 of the bathroom unit need to be set at substantially the same height.
In this case, it is necessary to provide appropriate drainage means facing the lower edge of the entrance so that water overflowing from the bathtub or water used in the washing place does not flow out to the dressing room through the entrance. Therefore, in the present embodiment, this drainage means is shown in FIG.
A drain pit 42 as shown in FIG.

In order to attach the drain pit 42 to the washing floor 1, the horizontal peripheral portion 3b and the peripheral rising portion 41 are required.
The part of b facing the lower edge of the entrance of the bathroom unit is cut out, and the drainage pit 42 is attached to this notched part. At this time, for example, the mounting portion 4 of the drain pit 42
2a is in contact with the upper surface of the horizontal peripheral portion 3b,
In other words, it is preferable to attach the drainage pit 42 to the washing floor 1 in such a manner that the upper surface of the horizontal peripheral portion 3b becomes a joining surface. As a result, the water overflowing from the bathtub and the water used in the washing place flow into the drainage pit 42 without flowing out to the dressing room via the entrance and exit, and after passing through the drainage through hole 42b, from the drainage outlet 2. And is discharged outside.

FIG. 5 is an intermediate sectional view showing a state where the drainage pit is mounted so as to abut on the upper surface of the horizontal peripheral portion of the washing floor. In FIG. 5, a wooden reinforcing member 51 on which FRP is sprayed on the surface is attached to the back side of the horizontal peripheral portion 3b of the washing floor.
On the upper part of the reinforcing member 51, a metal member 5 having an L-shaped section is provided.
2 is screwed. The drainage pit 42 is a reinforcing member 5
1 is screwed into the lower part of
Screw member 53 for pressing the upper surface of the horizontal peripheral portion 3b.
Use That is, by screwing the screw member 53 screwed into the drain pit 42, the tip of the screw member 53 comes into contact with the metal member 52, and as a result, the drain pit 42 is pressed against the upper surface of the horizontal peripheral portion 3b. The drain pit 42
Needless to say, a waterproof packing is interposed between and the upper surface of the horizontal peripheral portion 3b.

As described above, the washing floor 1 of the present embodiment is used.
Then, the horizontal peripheral portions 3b to 3d formed in a belt shape of a predetermined width
And a region excluding a pair of connection inclined portions 5c and 5d formed in an elongated band shape and a pair of drainage grooves 6a and 6b formed in a narrow band along the side facing the bathtub, that is, the center of the washing floor 1 Is formed in a region which occupies most of the area, and has a flat central inclined portion 4 having a constant inclined angle. In other words, in the present embodiment, a flat area occupying most of the washing floor 1 is sufficiently secured in the center of the washing floor 1. As a result, the legs of the installed chair do not protrude from the central single-slope portion 4 without any special attention, and the chair can be used in a stable state at all times.

In the conventional washing floor shown in FIG. 6, a total of three triangular wooden reinforcing plates need to be attached to the back side of the three regions 94a, 94b and 94c. All that is necessary is to attach one rectangular wooden reinforcing plate to the back side of 4. As a result, in this embodiment, the step of attaching the wooden reinforcing plate and the step of manufacturing the washing floor are simplified, and the cost can be reduced.

In the present embodiment, the drain grooves 6a and 6b are formed in a narrow band along the side facing the bathtub, so that the central sloping portion 4 occupying most of the center of the washing floor 1 is effective. The water that has flowed into the drain grooves 6a and 6b through the central one-side slope part 4 or the pair of connection slope parts 5c and 5d can be reliably guided to the drain port 2 without substantially reducing the area. In this case, a drain port 2 is formed near the center on the side facing the bathtub, a pair of drain grooves 6a and 6b are formed on both sides of the drain port 2, and a pair of connection gradient portions 5 are formed.
Since the drain grooves 6a and 6b are formed so as to be inclined downward from the drain holes c and 5d toward the drain port 2, the drain grooves 6a and 6b can be formed without setting the height of the bottom of the drain port 2 so low. Water gradient can be sufficiently ensured.

Further, in this embodiment, the horizontal peripheral portions 3b to 3b are located at substantially the same height as the lower edge of the entrance of the bathroom unit.
d, a drain pit 42 for setting the upper surface of d to prevent water from flowing out of the bathroom unit through the doorway to the dressing room.
Is provided facing the lower edge of the entrance, so that a so-called barrier-free type bathroom unit can be realized. In this case, one of the horizontal peripheral portions 3b to 3d similarly formed on the three sides is selectively used for mounting the drainage pit 42, thereby excluding the side facing the bathtub. The entrance of the bathroom unit can be selectively set along any one of the other three sides.

Further, since the drain pit 42 is attached so as to abut on the smooth upper surface having good finishing accuracy of the horizontal peripheral portion 3b, the drain pit is attached to the lower surface of the peripheral portion. In comparison, a high-precision molding method is not required for both the front and back sides when manufacturing the washing floor 1. That is, in the present embodiment, when the washing floor 1 is manufactured using a resin material such as FRP, it is not always necessary to use a high-precision and high-cost molding method such as hot press molding, but hand lay-up molding. It is possible to use a relatively low-precision and low-cost molding method such as that described above.

In the above embodiment, the washing floor of the present invention is applied to a barrier-free type bathroom unit, but the washing floor of the present invention can be applied to a general bathroom unit. Further, in the above-described embodiment, the example in which the washing floor of the present invention is applied to the bathroom unit is shown. However, the floor of the present invention is applied to other appropriate portions other than the bathroom unit (for example, the floor of a washroom). You can also.

[0035]

As described above, according to the present invention, in the center of the washing floor, a flat area occupying most of the floor, that is, a central sloping portion is sufficiently secured, so that special care is taken. Even without doing so, the legs of the installed chair do not protrude from the central one-sided slope, and the chair can always be used in a stable state. Further, in the present invention, it is only necessary to attach one rectangular wooden reinforcing plate to the back side of the central single-slope portion. Therefore, the attaching process of the wooden reinforcing plate and the manufacturing process of the washing floor are simplified, and the cost is reduced. Down can be planned.

Further, by forming the drainage groove in a narrow band along the side facing the bathtub, the water flowing into the drainage groove can be drained to the drainage port without substantially reducing the effective area of the central one-sided slope. It can be surely guided. In this case, by forming a drain outlet close to the center on the side facing the bathtub, it is possible to ensure a sufficient water gradient of each drain ditch without setting the height of the bottom of the drain outlet so low. Can be.

Further, the upper surface of the horizontal peripheral portion is set at substantially the same height as the lower edge of the entrance and exit of the bathroom unit, and a drain pit is provided to prevent water from flowing out of the bathroom unit through the entrance and exit. Thereby, a barrier-free type bathroom unit can be realized. in this case,
By selectively utilizing any one of the horizontal perimeters similarly formed on the three sides for the installation of the drainage pit, any one of the other three sides except the side facing the bathtub is used. The entrance of the bathroom unit can be selectively set along one side.

In particular, by adopting a structure in which a drain pit is attached so as to abut on a smooth upper surface with a high finishing accuracy in a horizontal peripheral portion, a high-precision molding method is not required for both the front and back sides when manufacturing a washing floor. For example, a relatively low-precision and low-cost molding method such as hand lay-up molding can be used.
