Abstract

PURPOSE:To smooth the elevating operation of a bathing bed and to make the upper portion of a moving support in a compact size by providing a decelerating driving mechanism for moving the moving support, which is constructed as a two-stage deceleration belt transmission and separating a driving electric motor from the moving support by the belt wrapping span of two sets of belts. CONSTITUTION:Belts 18 and 19 are respectively wrapped round between a pulley 15 and a pulley 17a and between a pulley 12 and a pulley 17b to form a two-stage belt driven decelerating driving device A, and a screw shaft 7 is decelerated and driven to rotate by an electric motor 13. Accordingly, at the time of elevating a bathing bed 24, the operation is conducted by a belt-type decelerating transmission in its initial stage, so that there is little shock. A wide enough space L is formed between a suspending frame 27 for suspending the bathing bed 24 and a moving support 4, and a wall frame 31a of a bath tub 31 can be fitted in the space L. A frame 9 of the decelerating driving device A is projected out to the bracket 23 side to which the suspending frame 27 from suspending the bed 24 is fixed to overlap each other, so that the upper portion of the moving support 4 is made in a compact size.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a bathing device for bathing bedridden elderly people and disabled people with limbs.

Conventional technology Conventionally, a movable column that slidably fits into a cylindrical fixed column erected on a trolley is provided, and a female screw is attached to the fixed column side.
The screw shaft that is screwed into the female screw is supported rotatably on the upper side of the movable column, and the screw shaft is rotated in the forward and reverse directions to raise and lower the movable column. This bathing device for persons with disabilities has a configuration in which an electric motor is rotated by a worm gear and a worm wheel gear at a reduced speed to move up and down, and a bathing bed on which a physically disabled person is placed is suspended from this movable column via a bracket. Ta.

Problems to be Solved by the Invention In the prior art, when operating a bathing bed by moving the electric motor forward and backward to raise and lower the movable column, a shock is generated at the beginning of the raising and lowering operation due to the transmission by the worm gear and worm wheel gear. This has the disadvantage of causing discomfort to the disabled person lying on the bed.Furthermore, the electric motor, worm gear, and worm wheel gear as a deceleration drive mechanism are concentrated at the top of the moving column, making the top of the moving column extremely high. Moreover, because the bathing bed is attached to a movable support and must be separated from the movable support by the thickness of the bathtub wall frame, which is a functionally essential configuration, the bracket is attached to the movable support for bath inspection. It had the disadvantage that it protruded a lot, making it difficult to create a compact configuration.

Technical Means for Solving the Problems In order to solve the problems of the conventional device, the present invention provides a movable support 4 that is movably fitted to a cylindrical fixed support 3 installed upright on a truck 1. A female screw 6 is attached to the fixed column side, and a screw shaft 7 that is screwed into the female screw 6 is rotatably supported on the upper side of the movable column 4. Attach the protruding underframe 9, and place the positive,
A small diameter pulley 15, a large diameter pulley 17a, and a small diameter pulley 17b attached to the drive shaft 13a of a reversible electric motor 13.
The counter pulley 17, which is provided on the same shaft, and the large-diameter pulley 12, which is attached to the head of the screw shaft 7, are arranged approximately in a straight line, and belts 18 and 19 are attached to these pulleys.
A deceleration drive device A is provided which causes the screw shaft 7 to undergo deceleration transmission rotation in a form in which the electric motor 13 is separated from the movable column 4 by winding the movable column 4.
A bracket 23 is attached to the bracket 23 and the tip side extends toward the motor side, and a bathing bed 24 on which a physically handicapped person is placed to take a bath is suspended from the tip side of the bracket 23.
The bathing device for persons with disabilities is characterized in that a space is provided between the suspension frame 27 and the movable support 4 so that the wall frame 31a of the bathtub 31 can fit therein.

Functions and Effects of the Invention As described above, this invention uses a two-step deceleration belt transmission as the deceleration drive mechanism for operating the movable column, so that the bathing bed on which the disabled person is placed, which is attached to the movable column, can be smoothly raised and lowered. In addition to being able to operate slowly by movement, the electric drive motor and moving column are separated by a span between the two belts when viewed from the top, and the system straddles the side wall frame of the bathtub between these spans. In this way, the bathing bed can be suspended from the upper part of the movable column with a bracket, and by providing this bracket below the speed reduction drive mechanism, a compact structure can be achieved.

position on the top of the motor 1 and operate the switch to turn the electric motor 1
3 is reversed, the movable support 4 is lowered until the disabled person on the bed 24 is immersed in the hot water, and the motor 13 is stopped.

In this way, a person with a disability is bathed, but since the movement of raising and lowering the bathing bed 24 on which the person with a disability is lying is initially performed by a belt-type deceleration transmission, there is little shock, and the process is quiet. Does not cause fear to people with disabilities as they are being lifted and lowered. Furthermore, since the underframe 9 of the deceleration drive device A protrudes toward the bracket 23 side to which the suspension frame 27 for suspending the bed 24 is attached and overlaps vertically, the upper part of the movable support 4 becomes compact. . After bathing, the electric motor 13 is reversed by operating a switch in the opposite direction to the above operation, and the bottom of the bathing bed 24 is slowly raised higher than the upper end of the wall frame 31a of the bathing tub 31, and then one trolley is moved. , then descend to an appropriate height and move to a predetermined location.

In addition, the screw shaft 7 and the boot IJ12 of the reduction drive device A of the embodiment
It is attached using a collar 34 and a slipping washer 35, so that if an overload is applied to the screw shaft 7, only the pulley 12 will idle and the screw shaft 7 or the female screw 6
This is to prevent damage to the product.
