Description

[Detailed description of the invention] The present invention relates to a bathing device for physically disabled people to perform rehabilitation training in bathtubs and swimming pools. This relates to a device that allows users to enter and exit the bath while rotating and moving up and down between the bathtub and the bathtub.

Disabled people who have difficulty walking, people with after-effects of surgery, etc. are trained to recover the functions of each part of their body by using buoyancy in an exercise bathtub, hot water, or cold water in a pool. In this case, the person with a disability will be transferred to a transport vehicle rather than a bed in the hospital room.
The patient is wheeled into the bathroom or pool room, and is then assisted by a nurse or a hydraulic lift to enter and exit the pool. Conventional hydraulic lifts are inverted L from the top of the column of a huge hydraulic cylinder.
It has a long, letter-shaped arm and a horizontal support frame with a chair or stretcher attached to it from the bottom end of the arm.When a patient is transferred to the stretcher outside the pool,
After manually rotating the stretcher into the pool, the column was reduced and bathed. The above-mentioned conventional bathing device requires a long hydraulic lift, so there is a limit to suppressing the oscillation when a large bending load is applied to the hydraulic lift.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a bathing device for physically disabled persons that can sufficiently cope with bending loads and suppress sway.

In order to achieve the above object, the present invention has the following configuration. That is, a support shaft to which a worm gear is fixed via a support leg is erected on the floor near the pool, a frame rotatably attached to the support shaft is provided with a worm meshed with the worm gear, and the frame A guide frame is installed vertically at the tip of a casing-like arm that projects horizontally from the body, a lifting frame with a fixed seat is interposed in the guide frame, and a hanging belt connected to the lower end of the lifting frame is inserted into the guide frame. The proximal end is
An electric motor is provided in the frame body and is connected to a drum provided in the arm so as to be capable of winding and rewinding the drum, and is connected to an electric control circuit to drive the worm and the drum, and when the hanging belt is loosened. The structure is such that a limit switch for stopping the lowering of the elevator frame by the electric motor is provided.

The present invention configured as described above has the following effects.

First, the lifting frame is moved up and down by an electric motor, and the support shaft only needs to bear the load, and the arm can also be short, so the overall structure is strong against bending loads.

In addition, when the lifting frame comes into contact with the floor or the bottom wall of the pool and the hanging belt loosens, a limit switch is activated and the lowering of the lifting frame is automatically stopped; The load will be received by the floor surface or bottom wall, and the chances of receiving bending load can be significantly reduced.

Of course, since the elevating frame is moved up and down and rotated at predetermined timing using an electric control circuit, a single nurse can easily take a physically handicapped person into and out of the bath.
