[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathing assistance device used for assisting a person with a physical disability in a general household to take a bath, in particular, to enter and exit a bathtub including bathing with hot water.

[0002]

2. Description of the Related Art As bathing assistance devices, there are known electric and hydraulic devices which move up and down and sideways with a stool suspended from above or supported from below.

[0003]

However, since all of the known devices are large-sized devices, occupy a large space, and are permanent, the bathroom itself is remodeled in a small bathroom or bathtub of a general household. Otherwise, there is a problem that it is difficult to use.

Accordingly, an object of the present invention is to provide a bathing assistance device having a simple structure and a small occupation space, which is suitable for use in a small bathroom or bathtub of a general household.

SUMMARY OF THE INVENTION According to the present invention, an object of the present invention is to provide an apparatus frame provided with a base and a bathtub wall stopper at the lower and upper side portions of a vertical column, respectively, and a vertical section of the apparatus frame. Hydraulic expansion (expandable) cylinder fixed to the lower end of the vertical column of the device frame or the base, fixed to the slider that is vertically movably attached to the column, and vertically movable to the vertical column on the slider A seat supported and engaged with the slider, which is rotatably (rotatably) inserted around the vertical column, and a flexible pipe with a valve for water supply and drainage including a water supply pipe and a drainage pipe connected to the hydraulic expansion cylinder. This is achieved by a bathing assistance device consisting of

[0006]

In general, the bathing assistance device of the present invention has the base at the lower end of the vertical column of the device frame installed at the bottom of the bathtub,
By setting the tub wall hook on the top of the tub wall on the washroom side so that it does not move to the tub,
Operate the valve with the water supply pipe of the flexible pipe for water supply and drainage connected to a water supply source (for example, a tap water tap), and the outer (tip) end of the flexible pipe for water supply and drainage guided outside the bathtub. By connecting the water supply pipe of the flexible pipe for water supply and drainage to the hydraulic expansion cylinder, the hydraulic expansion cylinder in the flexed (contracted) state expands and expands, and thereby the seat is raised via the vertical elevation of the slider. Is raised along a vertical column so that it occupies a position above the bathtub that is suitable for getting out of the hot water, or conversely, the drain pipe of the flexible pipe for water supply and drainage communicates with the hydraulic expansion cylinder by operating a valve. As a result, an appropriate amount of water in the inflated hydraulic expansion cylinder is discharged, and the slider deflects through descending along the vertical column of the slider, so that the sheet occupies a sinking position in the bathtub suitable for bathing. Or expanded hydraulic expansion cylinder In raised position of the upper portion of the over bets tub, by rotating the sheet about a vertical column, for use in the form of or to occupy a position which is suitable for out of the seat against the tub.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention can be implemented, for example, in the manner shown in the drawings.

In the illustrated example, a vertical column 12 forming the apparatus frame 11 is made of a tube, and a base 13 is fixed to a lower end, while a handrail 14 extending horizontally is continuously provided at an upper end. Is provided with a hook-shaped bathtub wall hook 16 via a hanging portion 15 extending downward in parallel with the vertical column 12.

A vertically movable disk-shaped slider 17 is inserted into the vertical column 12 of the apparatus frame 11. The vertical column 12 is mounted on the lower surface of the slider 17 and the upper surface of the base 13.
The upper end and the lower end of a pair of hydraulic expansion cylinders 18 made of a flexible hose are fixed with the interposed therebetween.

A rectangular sheet 20 is rotatably and vertically movable through a corner on a slider 17 on a vertical column 12 of an apparatus frame 11.
7 is supported by a slider 17 so as to move up and down through the up and down movement of 7.

Further, at the upper ends of the two hydraulic expansion cylinders 18,
A flexible pipe 21 for water supply and drainage is connected, and the flexible pipe 21 is connected to a flexible pipe 23 for water supply and a flexible pipe 24 for drainage via a switching valve 22.

As shown in FIG. 1, the illustrated example is installed on the bottom of a bathtub 25 via a base 13 of a device frame 11 and a hook-shaped bathtub wall hook 16 on a bathtub wall 26 at a boundary with a washing place. By hanging on the upper end, bathtub 2
5, while the outer end of the flexible pipe 23 for water supply is connected to a tap (not shown) of tap water as a water source, and the outer end of the flexible pipe 24 for drainage is guided to a washing place. Use with

That is, when a disabled person is put into the bathtub 25, the switching valve 22 is operated to connect the flexible pipe 23 for water supply and the flexible pipe 21 for water supply and drainage.
Tap water is introduced into the double hydraulic expansion cylinder 18. As a result, the hydraulic expansion cylinder 18 expands and expands, and the seat 20 ascends to a position slightly above the upper end of the bathtub wall through the accompanying elevation of the slider 17 along the vertical column 12. In this state, the sheet 20 is turned to the washing place side, and a person with a physical disability is seated on the sheet 20. Thereafter, the seat 20 is turned inside the bathtub 25 to move the whole body inside the bathtub 25, and then the switching valve 22 is operated to connect the flexible pipe 21 for water supply and drainage to the flexible pipe 24 for drainage. As a result, the water in the hydraulic expansion cylinder 18 is gradually drained by an appropriate amount, and the slider 23 descends along the vertical column 12 due to the water.
The sheet 20 is lowered toward the bottom of the bathtub 25, and the body is soaked.

On the other hand, when the bath 20 is taken out of the bathtub from such a bathing state, the seat 20 is vertically moved by supplying water into the hydraulic expansion cylinder 18 by operating the switching valve 22 in the same manner as in the first half. After being raised along the column 12, the sheet 20 is turned to the washing place side and lowered from the sheet 20.

This invention also includes a hydraulic expansion cylinder formed of a bellows body, a water supply / drainage flexible pipe connected to a lower end or an intermediate portion of the hydraulic expansion cylinder, and a water supply / drainage flexible pipe provided with a hydraulic expansion cylinder. A water supply / drainage passage communicating with the hydraulic expansion cylinder is provided on the slider or the base, etc., without connecting directly to the body, and a flexible pipe for water supply / drainage is connected to the outer end of the water supply / drainage passage of this slider. Instead of being directly attached to the slider, it can be embodied in various forms such as being inserted into an upright shaft attached to the slider.

[0016]

[Effect of the invention] As is clear from the above description, the bathing assistance device of the invention is basically formed on a vertical column of a device frame having a base for setting in a bathtub and a bathtub wall stopper.
Since it has a simple structure with a small occupied space where the hydraulic expansion cylinder and the seat are inserted, only operation of the valve and rotation of the seat are required, and after use, it can be removed from the bathtub and put away, It has a practical effect of being easy to use even in small bathrooms and bathtubs of ordinary households.
