[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a bathtub.
[0002]
[Prior art]
Commonly used bathtubs are often molded into a bowl shape composed of both side walls, a front wall, a rear wall, and a bottom face with plastic or metal, or made into a bowl shape with wood. And the rear wall of the bathtub where a bather falls is steeply inclined in a Japanese-style bathtub, and is gently inclined in a Western-style bathtub. Moreover, in the bathtub of Japanese and Western signature, it becomes this middle inclined surface.
[0003]
This will be described with reference to FIG. 7. As shown in FIG. 7, the Japanese-style bathtub 100 has a distance between the upper end of the front wall 101 and the upper end of the rear wall 102 of 800 to 1200 mm. The wall 102 has a steeply inclined surface close to about 90 °. Accordingly, the bather 105 takes a bath with his / her legs folded.
In the Western-style bathtub 300, as shown in (c), the distance between the upper end of the front wall 301 and the upper end of the rear wall 302 is 1200 to 1600 mm, and the rear wall 302 is a gently inclined surface. Therefore, the bather 305 takes a bath in a relaxed posture close to a figure lying on his back.
[0004]
Moreover, in the bathtub 200 of the Japanese and Western signature, as shown in (b), the distance between the upper end of the front wall 201 and the upper end of the rear wall 202 is 1000 to 1400 mm, and the rear wall 202 has an intermediate inclined surface. It has become. Accordingly, the bather 205 takes a bath in an intermediate posture.
As bathtubs that can change the inclination of the rear wall to Japanese style or Western style, bathtubs described in Japanese Utility Model Laid-Open Nos. 5-9387 and 6-37747 are known.
[0005]
The bathtub described in Japanese Utility Model Laid-Open No. 5-9387 has a bellows shape in which both side walls can be expanded and contracted, and the inclination of the rear wall is changed by changing the amount of expansion and contraction above and below the bellows-shaped side wall. It can be changed.
In addition, the bathtub described in Japanese Utility Model Publication No. 6-37747 is provided with two rows of guide rails attached to both side walls at different inclinations from the rear wall, and a plate is inserted between the two rows of guide rails. It is possible to change the inclination of the backrest (rear wall).
Moreover, as described in JP-A-4-224756 and JP-A-6-141996 as a relaxing bathtub, a floor cloth or an airtight sheet is attached at an intermediate height of the bathtub body. The bathtub is known.
[0006]
[Problems to be solved by the invention]
However, the preferred inclination of the rear wall varies depending on the taste and age of the person.
In general, for elderly and disabled people, if the rear wall has a gently sloping surface, when entering a bath, the body will rise, causing the body to become unbalanced and slip into the hot water. Then, a drowning accident can occur, so a bathtub with a steep slope in the back wall is good for the elderly and the disabled, and a gentle back wall can be relaxed for young people.
[0007]
In a bathtub where both sides of the wall are bellows-like, it is convenient because you can bathe by changing the inclination of the rear wall depending on the taste and age of the person, but the structure is complicated and the scales in the bellows bowl Etc. are liable to adhere, and there is a problem that it is difficult to remove scales adhering to the bellows.
Also, in a bathtub with guide rails on both side walls, the inclination of the rear wall can be changed by inserting the plate along the guide rail between the two rows of guide rails. If you are bathing without using this, this guide rail is inconvenient and inconvenient. In addition, there is a problem that scales are likely to adhere between the two rows of guide rails and the front and rear walls, and that the adhered scales are difficult to remove.
[0008]
In a bathtub with a floor cloth or an airtight sheet at the middle of the bathtub body, the back of the bather can bathe along the floor cloth or the airtight sheet, so you can relax and feel comfortable bathing. The cloth and the airtight sheet are easy to deform and are attached to the intermediate height of the bathtub, so when you enter the bathtub, put your soles on the floor cloth and the airtight sheet. When standing, there is a problem that the floor cloth and the airtight sheet are deformed and the legs are staggered, and the feet are not flat and the feet are not stable and difficult to enter the bathtub.
Further, there is a problem that the horizontal floor cloth and the airtight sheet are difficult to install in the bathtub, and that the structure is complicated, so that cleaning is difficult.
Therefore, an object of the present invention is to provide a bathtub in which the inclination of the rear wall can be easily changed, and further, it is difficult for scales or the like to adhere, and even if they adhere, it is easy to remove the scales.
Another object of the present invention is to provide a bathtub that is easy to enter a bathtub and that can be relaxed and bathed.
[0009]
[Means for Solving the Problems]
The present invention has been made to achieve the above object, and the invention according to claim 1 is a saddle type comprising a rear wall, a front wall, both side walls, and a bottom surface that form a gently inclined surface. And a reverse L-shaped backrest member composed of a horizontal piece and a standing piece at the upper end of the bathtub main body, and one end of the horizontal piece. The standing piece is erected on the bottom wall in a state where the horizontal piece is arranged almost horizontally by being fitted to the rear wall, thereby forming the inclined piece having a steeper slope than the rear wall. As a backrest portion, in a bathtub in which the backrest member is detachably attached to the bathtub main body, an armrest that hangs both elbows of a bather when the back wall is leaned on the back wall, the armrest and the rear wall A gap is provided between the side walls so that the standing piece can stand up between the two side walls. In both cases, by providing a locking recess in the vicinity of the boundary between the rear wall and the flange, the backrest member is detachably bridged from the locking recess to the gap between the armrest and the rear wall. It is the bathtub characterized by having attached.
[0010]
The invention described in claim 2 is composed of a fluid inlet / outlet disposed on the bottom surface of the bathtub according to claim 1 and a sheet-like stretchable body covering the fluid inlet / outlet, and allows fluid to enter / exit from the fluid inlet / outlet. Therefore, when the sheet-like stretchable body is freely expandable and contractible, and the fluid is poured into the sheet-like stretchable body and inflated, the shape of the upper surface of the expanded sheet-like stretchable body is a bathing bathed by bending a foot. It is made in the shape of a mountain along the back side of the person's foot. The foot in the second aspect of the invention refers to a portion extending downward from the waist. In the invention described in claim 3, the bent portion at the substantially center of the substantially inverted L-shaped backrest used in the bathtub according to claim 1 or 2 is foldable.
[0011]
(Function)
In the bathtub of the present invention, between the locking recess and the armrest and the rear wall, the reverse L-shaped backrest is substantially horizontal with one piece of the inverted L-shape being substantially horizontal and the other piece being steeper than the rear wall. Since it is tilted, it is bridged and is detachably attached, in the case of a person who likes a loose rear wall, for example, a young person, remove the backrest and take a bath.
Then, the back wall of the bathtub is a gentle slope, so you can relax and take a bath comfortably.
[0012]
For example, in the case of an elderly person or a handicapped person, a substantially inverted L-shaped backrest is attached to take a bath.
Then, since a substantially inverted L-shaped backrest with a steeper angle than the rear wall is attached in front of the rear wall of the bathtub, it is possible to bathe in the back of this steep backrest.
In addition, since this backrest is mounted between the armrest and the rear wall from the locking recess provided in the vicinity of the boundary between the rear wall and the heel, the conventional bathtub is used to attach this backrest. Thus, it is not necessary to attach a fixture such as a guide rail to the side wall. Accordingly, the side wall of the bathtub remains a smooth surface, and it is difficult for scale to adhere to the bathtub, and it is easy to clean even if scale is attached to the side wall.
[0013]
In the invention described in claim 2, the bather enters and exits the bathtub by drawing the fluid from the fluid inlet / outlet and contracting the sheet-like stretchable body.
Then, even if the bather enters and leaves with the soles on the contracting sheet-like elastic body, the feet are stabilized to support the bather's load on the flat floor below the sheet-like elastic body. It is easy to get in and out of the bathtub without wobbling.
In addition, when a fluid is introduced into the sheet-like stretchable body after bathing, the shape of the surface of the expanded sheet-like stretchable body becomes a mountain shape along the rear side of the bather's foot when bathing by bending the foot. Therefore, when the back side of the foot bent by the bather is placed on the sheet-like contraction body, the back side of the knee joint is supported by the sheet-form contraction body, so that the user can relax and take a bath.
[0014]
In the invention according to claim 3, since the bent portion at the center of the substantially inverted L-shaped backrest is made foldable, when the backrest is not used, it is smaller in shape when folded. Easy to do.
[0015]
