[Problems to be solved by the device]

 However, the conventional bathroom chair with the structure shown in Fig. 8 is not rotatable, so the user's body cannot be turned, and each time the caregiver moves back and forth to wash it. did not become. In order to eliminate this inconvenience, it may be possible to attach casters to the legs to make it mobile, but this is not preferable because the chair must be fixed by hand to wash the body such as limbs and back so that it does not move. In addition, since the conventional handrail has a fixed handrail, even if only the tip part is openable, it is inconvenient to get on and off, and there is relatively little space when storing when not in use or when placing it in an appropriate place. It was inconvenient in terms of handling, such as taking.

This invention has been improved in order to solve the above-mentioned drawbacks of the conventional bathroom chair, and the conventional fixed type chair can be rotated so that the body direction can be freely changed. It aims to provide a swivel chair for the bathroom, which can be fixed in any position by operation, and the whole handrail can be opened and closed, and can be hung in a position where it does not interfere when not in use.

[Action]

 The seat bearing mounting structure for receiving the seat pipe is such that the seat bearing is placed on a flat plate fixed to the upper surface of the connecting pipe of the leg so that the bottom surface of the seat bearing overlaps, and a screw pin that serves as the rotation center axis Then, the nut is tightened and fixed to the screw. Further, as the rotation lock device for the seat bearing, for example, a lock pin that is constantly pressed downward by a spring and slowly penetrates the seat bearing and the flat plate is attached to the bearing receiving side, and the lock pin is used as a lever. It is possible to use a mechanism having a mechanism whereby the lock of the seat bearing is released by pulling it upwards. The seat bearing was made by bending a single metal plate (stainless steel plate or iron plate) in order to simplify the structure and improve drainage. The sheet rotates 360 degrees about the screw pin with the upper surface of the flat plate as the sliding contact surface.

In the seat pipe and the handle pipe, for example, a tubular body made of the same pipe shorter than the pin is rotatably fitted to a connecting pin protruding from the joint end of the seat pipe, and the connecting pin is projected. It is connected by fitting the joint end of the handle pipe to the part in a detachable manner. Since the handrail is pivotally attached to the rotary cylinder so as to be vertically rotatable, the handrail pivots horizontally and vertically. Further, the supporting pipe for attaching the handrail to the seat pipe is connected by fitting the lower end of the supporting pipe to a connecting pin projecting upward on the seat pipe, and the attaching / detaching mechanism is, for example, the supporting pipe. L-shaped lock lever attached to the lower end of the rotatably in the left-right direction is positioned directly below the connecting pin, and is locked by horizontally rotating the lock lever Can be used.

According to this invention, the seat can be freely rotated by releasing the rotation lock device of the seat bearing, and the seat can be fixed at any position by locking the rotation lock device. You can freely change the orientation of your body while holding it, and you can fix your body in any orientation. Also, when getting on and off the chair, moving the lock lever of the handrail support pipe to the side releases the handrail lock, and the handrail can be opened, which makes it easy and easy to get on and off.
