DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wooden detached house as well as a condominium or other condominium, which is provided on a floor on the undressing room side of an entrance to a bathroom of a unit bath or the like. The present invention relates to a “waterproof pan (van)” for preventing rot due to moisture or water soaking.

[0002]

Recently, bathing styles have changed significantly compared to before. In the past, people used to squeeze the towels used in the bathroom, wiped themselves cleanly in the bathroom, and then came out to the dressing room. Nowadays, the use of Western-style towels is becoming popular, especially for young people. In other words, separately prepare a towel to wash your body in the bathroom and a towel to wipe your body after taking a bath,
After bathing, it has become common to go out to a dressing room with a wet body and wipe the body with a bath towel in the dressing room. For this reason, the dressing room, especially in the vicinity of the bathroom entrance / exit is always moist, and the service life of the flooring material at that location is extremely short, which is the current state of ordinary houses. In addition, this means not only the change in bathing method,
It is also due to the fact that the floor is not wiped frequently and is no longer maintained. For this reason, there has been a problem that the floor near the bathroom doorway comes off in about three years.

In the present invention, therefore, the vicinity of the entrance to the undressing room side of the bathroom (unit bath, etc.) of a wooden detached house or an apartment house (apartment, etc.), especially the flooring material under the bath mat, is not damaged by moisture and water soaking. The purpose is to protect and maintain the service life of the floor material in that part to the same extent as other parts. Moreover, in order to widely apply to general houses, construction is easy and it is necessary to reduce costs. In addition, care must be taken not to impair the warmth of the tree.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the hot water proof pan 1 of the present invention will be described in more detail. FIG. 1 shows a bathroom 2 to which an embodiment of a waterproof bath 1 according to the present invention is applied.
It is a top view which shows the example applied to the unit bus of the detached house. 2 and 3 are a perspective view and a vertical sectional view (A-A in FIG. 1) of the waterproof pan 1 in an attached state.
FIG.

The waterproof pan 1 is installed on the outside of the bathroom 2 having the bathtub 21, that is, on the floor at the entrance on the side of the undressing room 3. At the entrance of the bathroom 2, there is a door 22 that can be opened toward the bathroom.
Is suspended and provided. And the door 22
With the door closed, the door frame 2 facing the lower end face of the door 22
As shown in FIGS. 2 and 3, the lower frame 24 is provided at an end of a panel 26 constituting a floor panel of the bathroom 2. That is, the end of the floor (panel) 26 of the bathroom 2 extends upward in a substantially L-shape with respect to the floor surface to form the rising piece 25, and then, at the upper end of the rising piece 25, The lower frame piece 24 of the door frame 23 is disposed so as to extend horizontally. The vertical distance H between the bathroom floor and the lower frame piece 24 is about 80 to 90 mm in this embodiment.

The waterproof pan 1 of this embodiment is formed in a shallow rectangular tray shape by integral molding of plastic. That is, it is formed in a shallow box shape with a bottomed rectangular shape that is opened only upward. At an upper end portion of the waterproof pan 1, a flange portion 11 extending radially outward is continuously provided. And, as will be described later, the waterproof pan 1 is
The screw insertion holes for inserting the screws 9 when screwing the screws 9 and the like are formed in appropriate numbers and appropriate locations through the vertical direction.

The size of the waterproof pan 1 can be changed as appropriate regardless of the particulars. For example, the length L in the left-right direction is about 550-800 mm and the length W in the front-rear direction is W The thickness is about 450 to 600 mm, the vertical depth h is about 12 mm, and the thickness t is about 2 to 3 mm. In the illustrated example, the size of the tray excluding the flange 11 is the length in the left and right direction. L is 600-750 mm,
Length w in the front-rear direction is 450 to 550 mm, depth h in the vertical direction
Is 12 mm, the plate thickness t is 2 to 3 mm, and the width d of the flange 11 is 20 to 25 mm. Note that the depth h of the waterproof pan 1 is set to 12 mm because the thickness of the floor panel 4 laid on the joist 5 is generally 12 mm. This is because the bottom surface of the waterproof pan 1 can be placed on the joist 5 and the bottom surface of the flange 11 of the waterproof pan 1 can be overlapped with the upper surface of the floor plate 4 around the waterproof pan 1.

[0010] That is, the floor set is usually placed on a large pulley 6 (for example, 100 mm square) arranged along the left-right direction.
The joists 5 (for example, a height of 45 mm) are arranged in parallel at predetermined intervals (for example, 300 mm (exactly, 303 mm)) in the front-rear direction so as to intersect the pulling 6 at a right angle. (For example, the upper and lower thicknesses are 12 mm), and the waterproof pan 1 is attached by mounting the prevention pan 1 directly on the joist 5 instead of the floor plate 4, Is screwed to the floor plate 4 or the like at the time of floor plate construction. Screwing the flange 11 to the floor plate 4
After the flange 11 of the waterproof pan 1 is overlaid on the upper surface of the floor plate 4, the screw 9 is screwed into the floor plate 4 or the like from the upper surface of the flange 11 through the screw insertion hole of the flange 11.

In this way, the three-sided flange portion 11 except for the flange portion 11 on the bathroom 2 side is screwed to the floor plate 4. The flange portion 11 on the bathroom 2 side is shown in FIGS. 2 and 3. As shown in (2), after the outdoor end of the lower frame piece 24 of the bathroom 2 is overlapped on the upper surface of the flange 11, both are screwed. This is for guiding the water dropped from the lower frame piece 24 into the waterproof pan 1. In addition, as shown by a broken line in FIG. 3, the thickness of the flange 11 on the bathroom 2 side in the vertical direction may be increased.
That is, a block-shaped flange portion 11 ′ is formed so that the end of the waterproof pan 1 on the bathroom 2 side reaches the lower end surface of the waterproof pan 1 integrally with the flange portion 11 and the front side wall. By doing so, the bottom surface of the block-shaped flange portion 11 'is placed on the joist, and the lower frame piece 2 is inserted through the flange portion 11'.
4 will be supported by joists.

Incidentally, as in this embodiment, the thickness t is 2-3.
mm, the depth from the lower surface of the flange 11 to the bottom surface of the waterproof pan 1 (or the depth h of the waterproof pan 1 from the upper surface of the flange 11 to the upper surface of the bottom plate 12 of the waterproof pan 1) is 12 mm, and is simply formed in a tray shape. If only the joist pitch is 300 mm (303 mm), the waterproof pan 1 may bend downward at the middle part thereof. 150mm joist pitch
(151.5 mm) (see FIG. 4).
(A)). However, as shown in FIG. 4B, when the veneer board 10 or the like is discarded on the joist, the entire bottom surface of the waterproof pan 1 is placed in contact with the upper face of the discarded board 10. Therefore, it is not necessary to shorten the joist pitch. In the illustrated example, the thickness of the veneer plate 10 to be discarded in the vertical direction is about 12 mm.

Alternatively, instead of shortening the pitch of the joists 5, the thickness of the bottom plate 12 of the waterproof pan 1 may be increased while keeping the pitch of the joists 5 at the standard value of about 300 mm ( 5 and 6). At this time, the bottom plate 12 may be simply thickened, but as shown in FIG.
In addition, it is preferable to form a large number of holes 13 opening only downward. Here, a large number of holes 13 are formed in a diagonal lattice shape and open downward. With this configuration, the plurality of extending pieces 14 that are lowered downward serve as ribs, so that the waterproof pan 1 that is light and upper can be obtained. In other words, according to the waterproof pan 1 of this embodiment, since the extension piece 14 is formed to form the reinforcing structure, as shown in FIG. Can be. In the illustrated example, the collar 11
The vertical height h1 from the lower surface of the bottom to the upper surface of the bottom plate 12 is about 4 m.
m, the thickness t of the bottom plate 12 is about 2 mm, and the length h2 of the rib (extension piece) from the lower surface of the bottom plate 12 to the lower end of the extension piece 14 is about 6 mm.

A commercially available undressing mat, bath mat or the like can be put in the waterproof pan 1 for use. By installing the waterproof pan 1 at the bathroom entrance on the undressing room 3 side, even if you come out of the bathroom 2 into the undressing room 3 with your body still wet,
Water drops can be received with a plastic waterproof pan 1,
There is no danger of the floor being flooded and rotting. In addition, since the waterproof pan 1 is made of plastic, water accumulated in the waterproof pan 1 can be wiped off with a rag or the like.

In the above embodiment, the waterproof pan 1 is applied to a unit bath of a detached house. However, the present invention is not limited to this and can be applied to other bathrooms. For example, FIGS. 7 to 9 show an example in which the invention is applied to a unit bath of a condominium house. FIG. 7 is a plan view, FIG. 8 is a perspective view, and FIG. 9 is a vertical sectional view (BB sectional view in FIG. 7). ). Also in this embodiment, the waterproof pan 1 is installed outside the bathroom 2 provided with the bathtub 21, that is, on the floor at the entrance on the side of the undressing room 3, and the height of the floor on the side of the undressing room 3 is below the unit bath. Except for being disposed below the frame piece 24, other configurations are basically the same as the waterproof pan 1 of the embodiment of FIG.

The hot-waterproof pan 1 of each of the above constructions protects floor materials near the entrance to the bathroom 2 of the dressing room 3 and is formed by integral molding of plastic which can be mass-produced and can be provided at low cost. , And can be directly joisted,
Moreover, simultaneous construction can be performed by screwing during floor construction. Therefore, construction is easy, and maintenance of many houses can be facilitated. In addition, the mounting position is connected to or adjacent to the bathroom doorway, and can be used as a receiving tray for a ready-made mat (commercially available towels) to receive the drips. The hot water proofing pan 1 is not limited to plastic and may be formed of other materials. For example, aluminum, FRP,
It may be formed of ceramic, urethane, or the like.

FIGS. 10 to 12 show another embodiment of the waterproof pan 1 according to the present invention. FIG. 10 shows a waterproof pan main body, (a) is a front view, and (b) is a plan view. It is. Also, FIG. 11 shows a case in which
FIG. 12 is a plan view of a state where 0 is arranged, and FIG. 12 is a longitudinal sectional view of that state, showing a partly enlarged view.

The waterproof pan 1 of this embodiment is formed in a shallow rectangular tray shape by integral molding of plastic. That is, it is formed in a shallow box shape having a rectangular shape with a bottom and opened upward. In the illustrated example, the outer frame 11 is formed to be slightly thicker, and the upper end 11 of the frame 11 is formed.
a is formed in an arc shape. The hot water proof pan 1 of this embodiment is not limited to plastic and may be formed of other materials. For example, aluminum, FR
It may be formed of P, ceramic, urethane, or the like.

Dimples are formed on both upper and lower surfaces of the bottom plate 12 of the waterproof pan 1 respectively. That is, in the illustrated example, a plurality of protrusions 12a and 12
"a" is integrally formed vertically and horizontally in a lattice shape. The upper and lower protrusions 12a, 12a are formed at corresponding positions as shown in FIG. 12, so that the upper and lower protrusions 12a, 12a form a substantially circular cross section.

The size of the waterproof pan 1 can be changed as appropriate regardless of the particulars. For example, the outer dimensions of the waterproof pan 1 are about 550-800 mm in the left-right direction length L and about 450-800 mm in the front-rear direction length W.
The height h in the vertical direction is about 12 mm, and the thickness t of the bottom plate 12 is about 2 to 3 mm (about 2 m in the illustrated example).
m), and the inner dimension is about 5
00 to 750 mm, length w in the front-rear direction is about 400 to 550
mm, and the width d of the frame portion 11 is about 20 to 25 mm. The protruding height p of the protruding portion 12a from the bottom plate 12, p,
p is about 2 mm each. In addition, the bottom plate 12
The lower protruding portion 12a protruding downward from the lower end portion is configured so that its lower end portion is at the same height as the lower end surface 11b of the frame portion 11 or is located slightly above the lower end surface 11b of the frame portion 11. .

The dimples serve as reinforcing ribs and prevent the waterproof pan 1 from being deformed. Moreover, the upper dimple is used for the mat 20 arranged in the waterproof pan 1,
Since the water pan 1 is held slightly above the bottom plate 12 of the waterproof pan 1, not only is it possible to prevent the mat 20 from being immersed in water droplets that accumulate in the waterproof pan 1,
Always in a comfortable state.

In the waterproof pan 1, a mat 20 can be used while being laid. As the mat 20, a commercially available undressing mat or bath mat may be used, but a natural wood mat 20 is preferably used. Natural wood is more resistant to water than plywood. Moreover, natural wood has various useful effects such as warmth, humidity control performance, and heat retention characteristic of wood. As natural wood, various woods such as pine and cedar can be used in addition to cypress. In particular, cypress, especially inland cypress is preferably used. Japanese cypress has properties such as a soothing effect due to a fragrance or the like that calms the mind, woody properties that do not change over time, heat insulation, heat insulation, and the like. In addition, components such as hinokitiol and phytoncide contained in the hinoki wood have a sedative action and a bactericidal action, and can be said to be particularly suitable for a bare-footed mat.

The natural wood mat 20 disposed in the waterproof pan 1 may be constituted by a single plate, but the illustrated example shows an example constituted by a plurality of plates. That is, in FIG. 11, a four-cylindrical board 20 to 20 is formed in the shape of a scale. As shown in FIG. 12, the lower end 20a of the illustrated mat 20 is formed to have a size substantially conforming to the inner size of the waterproof pan 1, and when the mat 20 is disposed on the waterproof pan 1, the lower end peripheral edge is removed. The waterproof pan 1 is formed so as to protrude slightly above the upper end surface 11c of the frame portion 11 thereof. In the illustrated example, after projecting i = approximately 4 mm from the lower edge 20a (the upper end surface 11b of the frame 11), j =
It is configured to protrude upward by about 2 mm. This allows
By giving the plate material a thickness, the warpage of the plate material can be prevented (relaxed). Note that j at the upper end of the mat 20 is about 2 m.
The part m can be used by appropriately shaving it as it is used, and can be used in a comfortable state for a long period of time.

The waterproof pan 1 of the present invention is used by being placed on a floor plate 4 on the dressing room side of a bathroom entrance. In addition, waterproof pan 1
A rubber or the like may be appropriately attached to the bottom surface of the waterproof pan 1 to surely prevent the waterproof pan 1 from slipping on the floor plate 4. The waterproof pan 1 not only protects the floor of the dressing room from corrosion in response to the drips after the bath, but also uses natural wood such as hinoki mats for the mat 20 so that it can be used freshly in summer and warm in winter. You can get the warmth of a natural tree from the soles of your feet. In addition, a forest bathing effect can be expected.

Since the mat 20 is held above the bottom plate 12 of the waterproof pan 1 by the dimple projections 12a, the water drops accumulated on the bottom of the waterproof pan 1
Since the mat 20 is prevented from touching directly and the ventilation of the mat 20 is improved, the mat 20 is maintained in a comfortable state. Since the natural wood mat 20 is detachable from the waterproof pan 1, it can be used for a longer time if used in the shade. In some cases, it is also possible to replace only the mat portion with a new one.
On the other hand, since the waterproof pan 1 is formed by integral molding of plastic or the like, the mat 20 can be removed and wiped with a rag or the like for cleaning.

As described above, in the embodiment of FIGS.
To protect the dressing room floor from corrosion, simply use a waterproof pan 1
Not only to spread the warmth of the tree,
It is characterized in that the wooden saw 20 is replaceably held on the projection 12a of the dimple. Thus, after bathing, the user can wipe the wet body on the wooden scale 20 without mind, without having to worry about corrosion of the tree.
By the way, the hot water proof pan 1 of the embodiment shown in FIGS.
Is characterized in that it is movable and has the warmth of a tree, so that it can be easily used not only in a dressing room but also in other places such as a kitchen.

The hot water proofing pan 1 of the present invention is not limited to the configuration of each of the above embodiments, but can be appropriately changed. For example, in the above-described embodiment of FIGS. 10 to 12, an example in which the waterproof pan 1 is used without being fixed to the floor, and the pan is used, as in the embodiment of FIGS. Of course, it may be fixed and used by stopping or the like. That is, FIGS. 13 and 14 are a perspective view and a vertical cross-sectional view showing a usage state of the modified example of the hot water proofing pan 1 of FIGS. 10 to 12, and as shown in these figures, undressing of the entrance of the bathroom 2. It may be fixed to the floor on the room 3 side and used. The illustrated example shows an example in which the present invention is applied to a unit bus of a detached house. That is, dimples are formed in the waterproof pan 1 of FIG. 2, as in the embodiment of FIG.

The waterproof pan 1 shown in FIGS. 13 and 14 is basically provided with a flange 11 on the upper peripheral edge, and has the other configuration basically except that the lower surface of the bottom plate 12 is formed in a flat shape. The description is omitted because it is similar to the embodiment of FIGS. As described later, the flange portion 11 has a screw insertion hole for screwing the waterproof pan 1 to the floor plate 4 or the like.
It is formed in an appropriate number and at an appropriate location penetrating vertically. The depth of the waterproof pan 1 is about 12 mm,
This corresponds to a general thickness of 12 mm of the floorboard laid on the joist 5. Therefore, when installing the waterproof pan 1 instead of the floor panel 4, the bottom surface of the waterproof pan 1 can be placed on the joist 5 and the bottom surface of the flange 11 of the waterproof pan 1 It can be superimposed on the upper surface of the floor plate 4.

That is, the floor set is usually placed on a large drawer 6 (for example, 100 mm square) arranged along the left-right direction.
The joists 5 (for example, a vertical height of 45 mm) are arranged in parallel at predetermined intervals (for example, 300 mm) in the front-rear direction so as to intersect the pulling 6 at a right angle.
(For example, the upper and lower thicknesses are 12 mm), and the waterproof pan 1 of this embodiment is mounted on the floor plate 4.
Instead of placing the prevention pan 1 directly on the joist 5,
The flange 11 is screwed to the floor plate 4 or the like at the time of floor plate construction. The flange 11 is screwed to the floor plate 4 after the flange 11 of the waterproof pan 1 is overlaid on the upper surface of the floor plate 4.
The screw 9 is screwed into the floor plate 4 or the like through the screw insertion hole of the flange 11 from the upper surface of the flange 11.

In this way, the three-sided flanges 11 except for the flanges 11 on the bathroom 2 side are screwed to the floor plate 4. The flanges 11 on the bathroom 2 side are shown in FIGS. 13 and 14. As shown in (2), after the outdoor end of the lower frame piece 24 of the door frame 23 of the bathroom 2 is overlaid on the upper surface of the flange 11, both are screwed. Thereby, the water dropped from the lower frame piece 24 can be guided into the waterproof pan 1. As shown by the broken line in FIG. 14, the thickness of the flange 11 on the bathroom side in the vertical direction may be increased. That is, the flange 11 on the bathroom side of the waterproof pan 1 is a block-shaped flange 11 ′ reaching the lower end surface of the waterproof pan 1. By doing so, the bottom surface of the block-shaped flange 11 ′ is placed on the joist 5, so that the lower frame piece 24 is supported by the joist 5 via the flange 11 ′.

It should be noted that the wall thickness is 2-3 m as in this embodiment.
m, the depth from the lower surface of the flange 11 to the bottom of the waterproof pan 1 is 1
If it is simply formed in a tray shape as 2 mm, 30
With respect to a joist pitch of 0 mm, the waterproof pan 1 may be bent downward at an intermediate portion thereof.
It is preferably 50 mm (FIG. 4A). However, as shown in FIG. 4B, when the veneer board 10 or the like is discarded on the joist 5 having a pitch of 300 mm, the entire bottom surface of the waterproof pan 1 is brought into contact with the top face of the discarded board 10. Since it is mounted, there is no need to shorten the joist pitch.

Further, instead of shortening the pitch of the joist 5, the thickness t of the bottom plate 12 of the waterproof pan 1 may be increased while the pitch of the joist 5 is kept at a standard value of about 300 mm.
As in the embodiments 0 to 12, the dimples 12a may be formed on the lower surface of the bottom plate 12 to cope with the problem. When the bottom plate 12 is made thicker to cope with it, as shown in FIG.
In addition, it is preferable to form a large number of holes 13 opening only downward. Here, a large number of holes 13 are formed in a diagonal lattice shape and open downward. With this configuration, the plurality of extending pieces 12b that have been lowered downward serve as ribs, so that the waterproof pan 1 that is light and upper can be obtained. In addition, the dimples 12a formed on the upper surface of the bottom plate 12 prevent the waterproof pan 1 from warping.

The waterproof pan 1 shown in FIG. 15 is installed and used, for example, in the state shown in FIG. A mat 20 made of natural wood or the like is used in the waterproof pan 1 of each of the embodiments, similarly to the embodiment of FIGS.

The waterproof pan shown in FIGS. 10 to 12 can be applied not only to the unit bath of a detached house but also to the unit bath of an apartment house. 16 and 17
Is a diagram showing an example applied to a unit bath of a condominium house, FIG. 16 is a perspective view, and FIG. 17 is a longitudinal sectional view. Also in this embodiment, the waterproof pan 1 is installed on the outside of the bathroom 2, that is, on the floor at the doorway on the side of the undressing room 3, and the height of the floor on the side of the undressing room 3 is lower than the lower frame of the door frame 23 of the unit bath. Except for being disposed below the piece 24, the other configuration is basically the same as the waterproof pan 1 of each of the above-described embodiments in FIG.

[0035]

As described above in detail, according to the waterproof pan after hot water bath of the present invention, it is possible to protect the base material of the undressing mat and prevent the floor material from being rotten due to the drop of the bath. The service life of the floor material in the dressing room can be extended to the same extent as other places. Moreover, the waterproof pan after hot water of the present invention can be attached directly to a joist and screwed to a floor material or simply by placing it on a floor plate, or can be formed by integral molding of plastic or the like. it can. Therefore, the construction is easy and the cost is low, and it can be widely applied to ordinary houses.
Since the waterproof pan is made of plastic or the like, water and the like in the waterproof pan can be removed simply by wiping it with a rag or the like, so that maintenance is easy. In addition, if natural wood is used, various effects such as warming of trees and forest bathing effects can be expected.
