[1. Outline]
<First embodiment>
First, a bathtub with an entrance will be described with reference to FIG. 2a includes a bathtub 3 in which a bath wall 3a rises from a floor (washing place) 2 of the bathroom. An entry / exit room 4 is provided on a tank wall 3 a of the bathtub 3. The entry / exit room 4 is a room formed in a passage-like shape so that a bather can pass through the bath wall 3a with the legs P (see FIG. 1) without straddling. The entry / exit room 4 is provided with an outer door 5 and an inner door 6 on the washing room side and the bathtub side, respectively. Further, a water saving member 7 is provided in the access room 4. In the present embodiment, a water saving member 7 is held on the inner surface of the outer door 5. The access room 4 and the water saving member 7 constitute a bathtub mechanism 8 of the present invention.
In this figure, only the water saving member 7 held by the outer door 5 is shown, and illustration of the other water saving members 7 is omitted. Details of the water saving member 7 will be described later with reference to, for example, FIG.

Next, how the water saving member 7 works will be described with reference to FIG. For example, the lower diagram of FIG. 1 shows a state before a bather goes out of the bathtub 3 to the washing place 2. Hot water (water) having the same water level as the bathtub 3 flows into the entrance room 4. The inflowing water flows when the bather opens the inner door 6 and enters the entry / exit room 4. In this state, if the outer door 5 is opened to go to the washing place 2, all the water staying in the entry / exit room 4 will be lost as the outflow water V2.
On the other hand, if the water saving member 7 is provided in the entrance / exit room 4 as shown in the above figure, water flowing to the washing place 2 can be saved by the volume of the water saving member 7. What is actually lost is the volume of effluent indicated by the reference V1.

[2. Each configuration]
(Washing area 2, bathtub 3)
Returning to FIG. 2A, the washing place 2 and the bathtub 3 are, for example, what are conventionally called unit baths or system baths. These are bathrooms in which ceilings, bathtubs, floors, walls, and the like are molded in advance using a highly waterproof material at a factory or the like, and then assembled after being brought to the site.
FIG. 2 b shows the floor of the washing room 2 and the tub wall 3 a of the bathtub 3. In the present embodiment, the bathtub 3 is provided so as to be partially embedded under the floor of the washing place 2.
In addition, the tub wall 3a may not be formed integrally with the washing place 2. Furthermore, the bathtub 3 may be separate. For example, it may be a standing bathtub 3 placed on the washing place 2.

(Entry and exit room 4)
As shown in FIG. 2A, the entry / exit chamber 4 is provided with a passage having a substantially U-shaped cross section including a bottom 4a and passage walls 4b, 4b rising up from both ends of the bottom 4a. Are closed by an outer door 5 and an inner door 6, respectively.
In addition, as shown in FIG. 2B, the bottom 4a is raised from the floor surface of the washing place 2 by the raised portion 4c. The raised portion 4c is unnecessary when the height of the tank wall 3a is low.

(Outer door 5, inner door 6)
The outer door 5 and the inner door 6 are provided so as to cover the end faces (see reference numeral 4d) of the passage walls 4b, 4b. A packing (not shown) is provided on the end faces 4d. The outer door 5 and the inner door 6 are closed via packing between the outer door 5 and the end face 4d.
The outer door 5 and the inner door 6 are opened and closed outward (see a two-dot chain line). The doors 5, 6 and the passage walls 4b, 4b are connected by hinges, respectively. The hinge is conventionally known.
In addition, the material of the entry / exit room 4, the outer door 5, and the inner door 6 is preferably formed of the same material as that generally used for a system bus.

(Water saving member 7)
Next, the water saving member 7 will be described with reference to FIG. The front, rear, left, right, up, and down directions used in the following description are indicated by arrows in the drawing, respectively, along the front, rear, left, right, and up and down directions.
The water saving member 7 shown in the figure includes a rotating member 9 held on the inner surface of the outer door 5 (see FIG. 2), a side near the inner door 6 of the entry / exit room 4, and a passage wall 4b (upper part in FIG. 2). Of the passage wall 4b), and an L-shaped member 11 held on the inner surface of the passage wall 4b facing the inner door 6.
The water-saving member 7 is preferably brought into close contact with the leg P by elastically pressing the bather's leg P (see FIG. 1). This is because an extra internal space (space) for retaining water in the entry / exit room 4 is not provided.
Further, for example, the notches 9c and 10a (see the portion below the water saving member 7 in the drawing) for inserting a toe described later are formed with dimensions enough to push the toe while elastically deforming the water saving member 7. Is good. Further, in the water saving member 7 near the notch portions 9c and 10a, slits 7a extending upward from the lower surface and extending in the front-rear direction are formed in parallel. This is to make it easier to insert the toes by pushing them.
The height position of the upper end surface of the water saving member 7 is preferably higher than the water level assumed in the bathtub 3. If the water level is lower than the water level, an extra space in which water stays in the entrance / exit room 4 is generated.

(Material)
It is preferable that the water saving member 7 is made of a material that hardly absorbs water or a material that easily drains water even when absorbing water. Then, it is preferable that the material is made of a material that is pushed by the leg P, elastically deforms along the shape of the leg P, and restores its original shape when the pushing force is lost.
For example, a conventionally known material such as a cushioning material having weatherability is preferable, and a material obtained by blowing a synthetic resin is exemplified. More specifically, foamed polyethylene, foamed urethane, and the like. A material having water absorbency, or a material that repels water, such as a rubber cover, may be used.
Alternatively, a gel material mainly composed of silicon or urethane may be used. Further, the gel-like material may be used by being wrapped with a material that repels water, for example, a rubber cover.
As the material of the water saving member 7, a conventionally known material can be used.

(Rotating member 9)
The turning member 9 is a member that turns together with the opening and closing of the outer door 5. When the bather enters the entry / exit room 4 and then closes the outer door 5, the rotating member 9 is arranged around the leg P, and the extra space in the room is filled.
The rotating member 9 roughly includes a rectangular parallelepiped portion 9a (left front in the figure) and a plate-shaped plate portion 9b that is continuous from the rear surface of the rectangular parallelepiped portion 9a and extends rearward.
The rectangular parallelepiped portion 9a is arranged so as to fill the space above the upper surface of the toe of the left leg P of the bather (see S3 in FIG. 4). A cutout 9c is formed below the rectangular parallelepiped 9a. The notch 9c is formed by cutting out a portion corresponding to a toe when the outer door 5 is closed.
When the outer door 5 is closed, the plate portion 9b is arranged so as to fill a space above the ankle of the left leg P, for example, a space between the left side surface of the leg P near the knee and the outer door 5. You.

(Inner member 10)
The inner member 10 is a rectangular parallelepiped member arranged so as to fill the space above the access room 4 from the upper surface of the toe of the bather's right leg (see S3 in FIG. 4). The right side surface of the inner member 10 is in contact with or close to the inner surface of the inner door 6. The rear surface of the inner member 10 has a peripheral surface projecting rearward. A notch 10 a is formed in a portion below the inner member 10. The notch 10a is formed by cutting out a portion corresponding to the toe of the right leg P in advance.
An L-shaped bracket 16 is provided inside the inner member 10. The bracket 16 has a fixed portion 16a extending in the left-right direction in the drawing, and a shape holding member bent perpendicularly from the fixed portion 16a and extended so as to be parallel to the inner surface of the closed inner door 6. 16b. The inner member 10 is fixed to the passage wall 4b (the upper passage wall in FIG. 2A) via the fixing portion 16a. The shape holding portion 16b withstands the water pressure of the water flowing from the bathtub 3 and acts as a reinforcing member for holding the shape of the inner member 10.
A portion of the inner member 10 on the side of the bathtub 3 (near the reference numeral 18 in the drawing) constitutes a part of an upright wall 18 that closes the bathtub 3 side of the entry / exit room 4.

(L-shaped member 11)
The L-shaped member 11 is a member arranged on the rear side and right side of the bather's right leg P and so as to fill the space between the right leg P, the inner door 6, and the rear passage wall 4b (FIG. 4 S3). The L-shaped member 11, when arranged in the entry / exit room 4, faces the base 11 a extending to face the passage wall 4 b (the lower passage wall in FIG. 2 a) and the inner surface of the closed inner door 6. And a straight portion 11b extending like this. The right side surface of the straight portion 11b is in contact with or close to the inner surface of the inner door 6. The vicinity of reference numeral 18 in the drawing of the L-shaped member 11 constitutes a standing wall.
In the present embodiment, the vicinity of the distal end of the linear portion 11b is in contact with the inner member 10. The contact is made so as not to hinder the elastic deformation of the linear portion 11b (see the two-dot chain line in the figure). Note that some clearance may be provided without contact. The vicinity of the contact portion is a notch 19 formed in the upright wall 18. In addition, slits 11c, 11c are formed on the left and right surfaces of the straight portion 11b so as to extend in the vertical direction toward the inside of the straight portion 11b. This is for facilitating elastic deformation of the straight portion 11b.
An L-shaped bracket 17 is provided inside the L-shaped member 11. The bracket 17 includes a fixing portion 17a extending along the base portion 11a, and a shape holding portion 17b bent perpendicularly from the fixing portion 17a and extending in the same direction as the straight portion 11b. The L-shaped member 11 is fixed to the passage wall 4b (the lower passage wall in FIG. 2A) via the fixing portion 16a. The shape holding portion 16b is a reinforcing member for holding the shape, with some resistance to the water pressure of the water flowing from the bathtub 3.
In the present embodiment, the shape holding portion 16b reaches near the middle thereof in the direction in which the linear portion 11b extends. For this reason, the straight portion 11b from the vicinity of the middle to the tip is curved by elastic deformation (see a two-dot chain line in the figure). The bather elastically deforms the distal end side of the linear portion 11b with the leg P, and moves between the access room 4 and the bathtub 3.

(Turntable 12)
Returning to FIG. 2A, a turntable 12 made of a circular plate-like member is provided on the tank wall 3a. A bather can sit on the turntable 12 and change his or her body orientation while in the sitting position. The point indicated by the symbol O (see FIG. 4) is the center of rotation of the turntable 12. The turntable 12 is a conventionally known one.

[3. How to get in and out of the bathtub]
(How to get in and out of the bathtub 20)
Next, a method for entering and leaving the bathtub of the present invention (hereinafter simply referred to as an entry and exit method) will be described with reference to FIG. The access method 20 shown in the figure has, as a main configuration, a step of disposing the water-saving member 7 around the bather's leg P with the outer door 5 and the inner door 6 of the access room 4 closed. ) And a step of opening the inner door 6 to enter the bathtub, or opening the outer door 5 and exiting to the washing place 2 (see S5). First, a method in which a bather enters the bathtub 3 will be described.

(Step S1)
In a step S1 shown in FIG. 4, the bather's leg P is in the washing room 2, and the bather is sitting on the turntable 12. The inner door 6 is closed. On the other hand, the outer door 5 is open. The rotating member 9 is outside the access room 4. That is, it is in a state where it is largely open from the entrance to the inside of the entrance room 4. Therefore, the bather can easily access the inside of the entry / exit room 4. In addition, the two-dot chain line shown in the figure represents the locus of the leg P of the bather.

(Step S2)
Next, the bather enters the entry / exit room 4. The bather turns the leg P into the entry / exit room 4 while rotating the turntable 12. In the present embodiment, for example, the toe of the right foot is inserted so as to be pushed into the notch 10a of the inner member 10.

(Step S3)
The outer door 5 is closed. At this time, since the rotating member 9 elastically presses the leg P and makes close contact with each other, the empty space in the access room 4 can be filled efficiently. At this time, a part of the water-saving member 7 may partially jump out of the water surface due to elastic deformation.

(Step S4)
Open the inner door 6. Water enters the entry / exit room 4 from the bathtub 3 and reaches the same water level as the bathtub 3. At this time, even if the outer door 5 is accidentally opened, since the inner member 10 and the L-shaped member 11 (the standing wall 18) close the opening on the bathtub 3 side, it is possible to prevent water from flowing to the washing place 2 at once. .

(Step S5)
Next, the bather enters the bathtub 3. At this time, the straight portion 11b of the L-shaped member is elastically deformed by the leg P so as to be curved (see a two-dot chain line in FIG. 3), and the cut 19 is pushed open. When the leg P passes through the notch 19, the water saving member 7 including the elastically deformed linear portion 11b returns to its original shape. Then, the user closes the inner door 6 and takes a bath.

Next, a method of getting out of the bathtub 3 will be described. This exiting method is substantially the same as the above-mentioned entering method, and therefore only different portions will be described, and description of the same portions will be omitted.
(S5): The bather sits on the turntable 12. Open the inner door 6. At this time, the outer door 5 is closed.
(S4): The leg P is put into the entry / exit room 4 while rotating the turntable 12. At this time, the leg P is inserted while the linear portion 11b of the L-shaped member is mainly elastically deformed by the leg P. Then, both toes are pushed into the cutouts 9c and 10a of the water saving member.
(S3): Close the inner door 6.
(S2): Open the outer door 5. Although the water inside the access room 4 flows out to the washing place 2, the amount of water flowing out can be reduced by the volume of the water saving member 7.
(S1): The turntable 12 is rotated, and the leg P is put out to the washing place 2.

[4. Other Embodiments]
<Second embodiment>
(Bath Organization)
Hereinafter, another embodiment of the bathtub mechanism 8 of the present invention will be described. This embodiment is substantially the same as the first embodiment described above, and therefore only different portions will be described, and description of the same portions will be omitted.
FIG. 5A shows another embodiment of the water saving member 7 of the bathtub mechanism 8 of the first embodiment . Bath tub Organization, to the first embodiment, is different from the shape of the water-saving member 7. Saving members tub Organization 14 has a shape substantially fills the interior volume of the loading and unloading chamber 4. At the center of the water saving member 14, a slit 14a extending from the washing place 2 toward the bathtub 3 is formed. The bather puts the leg P in the slit 14a. For this reason, since there is almost no extra space, the water saving effect is high. The height of the water saving member 14 is set to the same level or higher than an assumed water level without elastic deformation. This is to minimize the amount of water entering the entry / exit room 4 from the bathtub 3 when the leg P comes off from the water saving member 14.

  The water saving member 14 almost blocks the entrance of the entry / exit room 4 on the side of the washing place 2. However, since the water-saving member 14 is a flexible material that can be elastically deformed, even if the leg P cannot be accurately arranged in the slit 14a, the leg P can be guided to the slit 14a while elastically deforming the water-saving member 14 with the leg P. Can be.

(Modification)
In the above-described embodiment, the slit 14a is formed, but the slit is not formed in the water saving member of the modified example. FIG. 5B schematically shows a water saving member according to a modification. Although the water saving member 15 shown in the figure substantially occupies the internal area of the entrance / exit room 4 in plan view, its height is set to such a degree that the bather can raise the leg P.
The bather enters the entry / exit room 4 while stepping on the water saving member 15 (see the right side of FIG. 5B). When stepped on with the legs P, the water-saving member 15 is elastically deformed and driven away above the entrance / exit chamber 4 (see the symbol t in the figure). When the leg P comes off, the water saving member 15 returns to its original shape (see the left side of FIG. 5B).

[5. Other about each configuration]
(Sliding member)
A sliding member (not shown) that reduces friction between the bather and the leg P may be provided in a portion where the bather elastically deforms the leg P. For example, it is preferable to use a synthetic resin material such as that used for a body towel and a large mesh material. Body towels are compatible with the skin and dry easily.
Such a sliding member should be provided near the tip of the linear portion 11b of the L-shaped member, or on the convexly curved peripheral surface of the inner member 10, specifically, near the contact with the linear portion 11b of the L-shaped member. Good.

(Another embodiment of water saving member 7)
Another embodiment of the water saving member 7 of the present invention will be described. The water saving member in the present embodiment is almost the same as the water saving member 7 in the above-described first embodiment, and therefore only different portions will be described, and description of the same portions will be omitted.
FIG. 6 shows another embodiment of the water saving member. The water saving member 21 shown in the drawing is different from the water saving member 7 of the first embodiment in that the shape of the rotating member 9 is different and that the water saving member 21 further includes a triangular portion.
The rotating member 9 of the water saving member 21 has a portion near the distal end of the plate portion 9b extending so as to fill the space between the calf of the left leg P of the bather and the entrance / exit room 4 (see reference numeral 21a).
The triangular portion 21b is a substantially triangular prism-shaped member, and is provided between the rotating member 9 and the L-shaped member 11 when the outer door 5 is closed. The triangular portion 21b is disposed so as to fill the space between the left and right legs P, the calf of the left and right legs P, P. The triangular portion 21b has a surface corresponding to the base of the triangle fixed to the passage wall 4b (the lower passage wall in FIG. 2A). Further, slits 21c, 21c are formed in the left and right surfaces of the triangular portion 21b, and extend inward and extend in the up-down direction. The triangular portion 21b is easily elastically deformed, so that a bather can easily enter and exit.

(Angle hinge 22)
FIG. 7 shows a mounting portion (angle hinge) 22 for mounting the inner door 6 to be able to open and close. The figure shows a state in which the inner door 7 is opened as viewed from the inside of the entry / exit room 4 (corresponding to an arrow A in FIG. 2). In the drawing, reference numeral T1 denotes a state in which the inner door 6 is closed, T2 denotes a state in which the inner door 6 is slightly opened, and T3 denotes a state in which the entrance / exit chamber 4 is almost fully opened.
The angle hinge 22 has a pivot P for opening and closing provided on the bathtub 3 side of the inner door 6 outside the corner P1 (see T1). Therefore, when the inner door 6 is opened even slightly (from step T1 to step T2), a gap 22a (see T2) is generated between the inner door 6 and the passage wall 4b. Water flows from the bathtub 3 into the access room 4 through the gap 22a.
Returning to FIG. 4, for example, in step S <b> 3, water does not accumulate in the access room 4, but a large amount of water accumulates in the bathtub 3. Therefore, there is a force to turn the inner door 6 toward the bathtub 3 to open it against the water pressure. However, when the inner door 6 is slightly rotated, a gap 22a (see FIG. 7) is formed on the rotation axis P side of the inner door 6, and water flows in. For this reason, since water flows in from both sides of the tip side of the inner door 6 and the rotation axis P side, the inner door 6 can be easily opened (see step S4).
In addition to the angle hinge, for example, when the inner door 6 is opened, a gap 22a is formed between the inner door 6 and the passage wall 4a so that water flows in from the rotating shaft side when the inner door 6 is opened. It is better to use

(Packing spring)
FIG. 8 shows a packing and a biasing member (spring portion) provided on the passage wall 4b. The packing 23 and the spring portion 24 are provided on the end surface of the passage wall 4b on the inner door 6 side (see reference numeral 4d in FIGS. 2 and 8).
