Abstract

PURPOSE:To obtain a simple and safe going in-and-out device in a bathtub, by which an aged or physically handicapped person can go in and out freely for himself. CONSTITUTION:A seat plate 2 which can be moved vertically by air pressure is attached to a bathtub 1, and a person sits down on this seat plate 2 and goes into the bathtub 1, so that it will suffice that he sits down on this seat plate 2 and changes a direction of the body at the time of going out therefrom, as well. In such a manner, since a person sits down on the seat plate 2 and can go in and out to and from the inside of the bathtub 1, this device is very convenient and safe to an aged or physically handicapped person.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for entering and leaving a bathtub which is convenient and safe for an elderly person and a physically handicapped person to enter and leave the bathtub.

[0002]

2. Description of the Related Art Since a normal bathtub has a step difference between the floor of the washing room and the edge of the bathtub of 300 to 500 mm, and the depth of the bathtub (height between the edge and the inner bottom) is about 500 to 600 mm,
It is very difficult for the elderly and people with disabilities to come and go,
It is dangerous because it is slippery. As conventional measures against this, measures such as mounting a large-scale crane-type device in the bathroom, mounting a handle or the like on a bathtub or a wall, lowering a strap caught from the ceiling, and reducing a step are made.

[0003]

However, the crane type construction requires a large amount of work and requires a high equipment cost, and in the case of a handle or a clasp, it can be used for people who have inconvenient hands or who are weak. In addition, if the step is small and the step is small, the capacity of the bathtub becomes small, or the bathtub becomes shallow and the bathing itself becomes inconvenient.

An object of the present invention is to provide an entrance / exit device for a bathtub that can be safely put in and out by one person even if there is a step similar to that in the conventional case.

[0005]

The structure of the entrance / exit device for a bath according to the present invention is as follows.

A stool is arranged in a part of the bathtub so as to be movable up and down, and a vertically moving device that expands by injecting air pressure and contracts by discharging is attached to the lower part of the waving plate, and a vertically moving device and a compressed air generator The operation panel for connecting compressed air to the vertical movement device from the compressed air generation device via the conduit or for extracting the compressed air from the vertical movement device is a part of the bathtub or one of the side walls. An entrance / exit device for a bathtub that is attached to a section.

An air vent valve or a cock may be attached to a part of the stool so that the air pressure in the vertical movement device for the stool is lowered to lower the stool. Also, connect the compressed air pressure generator to the foam nozzle attached to the bathtub,
It may be configured to be shared.

[0008]

When entering the bath tub, the compressed air generated by the compressed air generator is introduced from the conduit into the vertical movement device of the stool, and the stretching action of this device causes the stool to move to approximately the height of the tub edge. Set.

In the washing room, the bather first sits on this stool, turns his body and puts his feet in the bath, and then operates the operation panel to open the vertical movement device or the air vent valve and cock to compress from the inside. Deflate the air. In this way, the vertical movement device of the waist-seat contracts due to the weight of the weight applied to the waist-seat, and the body together with the waist-seat sinks into the bathtub. In addition,
After sitting on the stool, a rotating plate may be mounted on the stool so that the body can be turned around easily. The bather may remove all the compressed air from within the vertical movement device of the stool to let it sink to the bottom of the bathtub, but if he stops the bleeding on the way and sets the stool slightly higher than the bottom. ,
It is easy to take a bath while sitting on a chair.

Next, when coming out of the bathtub, the operation panel is operated to drive the compressed air generator, and when compressed air is introduced into the vertical movement device of the stool from the conduit, the vertical movement device of the stool expands. Then, the bather raises the stool while still sitting, and makes it almost at the same height as the edge. As a result, the body can be easily exited from the bathtub toward the washroom.

[0011]

1 to 3 show an embodiment of the present invention and its operation.

In the figure, 1 is a bathtub, 2 is a vertically movable stool which is incorporated in a part of the tub 1, 3 is a stopper for the stool 2, and 4 is a vertical movement guide for the stool 2.
Reference numeral 5 denotes a waist plate vertically moving device (hereinafter referred to as "vertical moving device") incorporated between the lower surface of the waist plate 2 and the bottom surface 1'of the bathtub 1, and is made of a bellows-like rubber or synthetic resin sheet. The bottom is closed at the bottom of the bath 1. The vertical movement device 5 may be configured in a bag shape that is watertightly and airtightly independent from the bathtub 1 side.

6 is a compressed air inlet provided in the vertical movement device 5, 7 is a conduit, 8 is a compressed air generator (compressor or air pump), and 9 is a three-way switching valve attached to the conduit 7. , This valve 9 is a control panel 10
You can open and close and release (release) air with the operation button. An operation switch for the compressed air generator 8 is also attached to the operation panel 10.

As shown in FIG. 2, in the above apparatus, the operation switch is turned on before taking a bath and the stool 2 is raised to a height substantially close to the edge of the bath tub 1.
Turn the foot inside and press the operation button.
3 is switched to the air discharge side, air is released from inside the vertical movement device 5 as shown in FIG. 3, and the stool 2 is lowered into the bathtub 1 by the weight of the weight, and this action sinks the body into the hot water. You can Next, when leaving the bathtub 1, the valve 9 is switched and the operation switch is turned on.
From this, compressed air is introduced into the vertical movement device 5 through the inlet 6, the vertical movement device 5 extends upward, and the stool 2 rises together with the body of the bather. Since the rising is stopped by the stopper 3, the bather can easily get out of the bathtub 1 by changing the direction of the body to the washing room while sitting on the stool 2.

In the case of the embodiment, the valve 9 is operated to operate the lowering of the stool 2. However, an air vent valve or cock corresponding to this valve 9 should be directly attached to the stool 2. May be.

[0016]

As described above, according to the present invention, a stool that can be moved up and down by pneumatic pressure by automatic operation is installed in the bathtub, and the stool is seated on the washroom side, and then the body is turned into the bathtub. If you want to sink and leave, you can raise the stool to near the edge of the bathtub and turn your body around while sitting. As a result, it becomes very safe and safe for an elderly person or a physically handicapped person to take a bath alone.

Further, since the device of the present invention drives the stool up and down by utilizing the air pressure, the device is simple, and since it does not use electricity, there are few failures.

Further, when a bubble nozzle is attached to the bathtub or when the bubble nozzle is attached, if a compressed air generator for sending compressed air to this bubble nozzle is also used as a compressed air generator for the apparatus for moving in and out of the present invention, Only one compressed air generator is required, which simplifies the device and saves equipment costs.
