Function The outline of the operation of this device when bathing a patient using the device of the present invention is as follows:
The patient is made to sit down, and the lift switch 32 is operated to extend the column 2 to which the chair 33 is attached. Pillar 2
When the chair 33 is extended and the chair 33 reaches the highest position, the key 28 for locking the chair 33 automatically moves the chair 33 to the chair mounting frame 17.
It comes off from the lower hole 29 of. Manual pin 4 at this position
0 by hand, pull it out from the upper hole 41, and manually rotate the chair mounting frame 17 in the horizontal direction. When the chair mounting frame 17 is rotated by a predetermined angle (for example, 180 degrees) while the manual pin 40 is released, the manual pin 40 fits into the other upper hole 41 and the rotation of the chair mounting frame 17 is locked.

Next, the lift switch 32 is operated to contract the support column 2, and the chair 33 is lowered and stopped at an appropriate position while checking how well the patient has soaked into the hot water. At this time, when the support column 2 contracts, the keys 28 are automatically inserted into the lower holes 29 (four places in the embodiment) at other predetermined positions of the chair mounting frame 17, and the rotation of the chair 33 with respect to the support column 2 is doubly locked. has been done.

When you finish bathing, operate the lift switch 32 to extend the column 2 to the maximum extent, automatically release the key 28, and then release the manual pin 40 in this state.
is lifted and the chair mounting frame 17 is rotated toward the washing area, and then the manual pin 40 is released and the chair 33 is positioned above the washing area. When the chair 33 reaches a predetermined position on the washing area, the manual pin 40 locks the chair mounting frame 17 to the support column 2. When the support column 2 is retracted, the key 28 fits into the chair mounting frame 17 and the chair 3
3 rotation is doubly locked. The chair 33 is lowered to an appropriate height, the patient is lowered from the chair 32, and the bathing is completed.

Next, the operation of the rotation prevention mechanism 21 will be described in detail.

A key member 24 is pushed up by a spring 23 and attached to the lower part of the receiver 15 attached to the outer periphery of the lower part of the outer cylinder 6.
However, when the outer cylinder 6 reaches the highest position, the disc part 26 hits the protrusion piece 25 protruding from the inner cylinder 5, and the key member 24 is pushed down against the outer cylinder 6, and the chair mounting frame 17 is drilled. The key 28 is removed from the lower hole 29 provided in the opening.

When the key 28 is removed from the chair mounting frame 17, lift the manual pin 40 and remove the chair mounting frame 1.
When the manual pin 40 is removed from the upper hole 41 of 7, the chair mounting frame 17 rotates relative to the outer cylinder 6.

The expansion and contraction of the strut 2 is achieved by introducing pressurized water (for example, tap water) into the water conduit 9 communicating with the bottom surface of the inner cylinder 5 via a pressurized water electromagnetic valve 30 and injecting it into the inner cylinder 5, thereby raising the piston 8. Let's do it. Moreover, if the pressurized water filled in the inner cylinder 5 is drained via the drain solenoid valve 31 connected to the water pipe 9, the piston 8
The weight of the chair 33, etc. is added to the own weight of the piston 8, and the piston 8 descends, causing the support column 2 to contract.

The pressurized water electromagnetic valve 30 and the drain electromagnetic valve 31 are opened and closed by voltages selected and applied from the lift switch 32.

The lower leg support 35 of the chair 33 is for placing the lower leg of the patient, and supports the lower leg at approximately the same height as the buttocks. The handle 38 rotates around the base end of the attachment. Before the patient sits on the chair 33, the handle 38 is raised upward, and after the patient has sat down, the handle 38 is lowered and rotated to the horizontal recumbent position. make it move.

Effects of the invention In this invention, the chair mounting frame, which is rotatably fixed to the outer cylinder of the support, is always kept in a state where it is prevented from rotating relative to the outer cylinder, and the support reaches its maximum extension state. The outer cylinder is provided with a rotation prevention mechanism that automatically releases the above-mentioned rotation prevention for the outer cylinder only when the outer cylinder is closed. According to this configuration, the chair does not rotate relative to the support even if the manual pin is removed unless the support is at its maximum extension and the chair is at its highest position. If you move the chair to a specified position on the top or a specified position on the bathtub and insert the manual pin into the hole at the top, even if there is an error such as the manual pin coming out while the chair is being moved up and down, the chair will not rotate relative to the support. There's nothing to do. Therefore, accidents such as the chair colliding with the edge of the bathtub are eliminated, and bathing can be performed safely.In addition, the chair rotates relative to the support while the support is expanding and contracting, causing discomfort to the patient or putting them in danger. There is no need to do anything else, and you can bathe safely and with peace of mind.
