Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. Embodiment 1

FIG. 1 is a front view of the rotary transfer chair of the first embodiment, and FIG. 2 is a plan view of the rotary transfer chair of the first embodiment. A disk-shaped support 101 is installed on the floor, and supports the entire rotary transfer chair. Support base 10
1 is a cylindrical upright rotating shaft 10 extending upward from the center of
3 is upright. The support 101 and the upright rotating shaft 103 are firmly attached. Annular handwheel 1
The manual handle 102 is firmly attached to the upper end of the upright rotary shaft 103. Near the lower end of the upright rotating shaft 103, the horizontal movable plate 10
4 is rotatably mounted and arranged in a horizontal plane. When the manual handle 102 is manually rotated clockwise or counterclockwise, the horizontal movable plate 104 is accordingly rotated clockwise or counterclockwise around the upright rotating shaft 103 as shown by an arrow 5. Rotate clockwise. Near the outer periphery of the rotation of the horizontal movable plate 104, a chair 105 is mounted upright. The chair 105 includes an upright portion and a seat, and the upper surface of the seat is arranged in a horizontal plane. Chair part 105 is horizontal movable part 1
04 can be rotated.

When the subject 20 sits on the seat of the chair 105 and places his feet on the horizontal movable plate 104, the knee can be bent by about 90 °, and the subject 20 can sit in a comfortable posture. When the subject 20 rotates around the chair 105 and faces the manual handle 102 and grasps the manual handle 102 with his / her hand, the elbow is in a comfortable posture in which the elbow is bent by about 90 °. Therefore, the subject 20 can turn the manual handle 102 while sitting on the chair 105, and accordingly, the chair 105 rotates around the upright rotation shaft 103.

Second Embodiment FIGS. 3 and 4 are front sectional views of a rotary transfer chair according to a second embodiment, showing a state in which a lock mechanism is functioning and a state in which the lock mechanism is released, respectively. ing. FIG.
FIG. 9 is a plan view of a rotary transfer chair according to a third embodiment.

In the second embodiment, the support table 101,
The upright rotation shaft 103 and the manual handle 102 are integrally formed. A hollow cylindrical first flange 141 and a second cylindrical flange 142 stand upright from the horizontal movable plate 104.

An upright rotating shaft 103 is inserted through the hollow portion of the first flange 141, and a ball bearing is interposed between the shafts. Also, the horizontal movable plate 104 and the support 1
01 and a ball bearing is interposed. Therefore, the horizontal movable plate 104 can freely rotate around the upright rotation shaft 103.

A first flange 141 is provided near one end of the horizontal movable plate 104, and a chair 1 is provided near the other end.
05 stands upright.

The cylindrical portion of the cylindrical lock pin 106 having a side branch is inserted through the hollow portion of the second flange 142. A grip portion is provided at the upper end of the lock pin 106 so that the subject can easily grip it with his / her hand. Lock pin 106
A helical spring 107 is attached near the free end of the side branch of the helical spring, and the other end of the helical spring 107 is attached to the horizontal movable plate 104. Therefore, the lock pin 106 is urged vertically downward by the spring force of the helical spring 107.

The support 101 has a cylindrical lock hole 18.
1, 182, 183, 184, 185, 186 are arranged. When the horizontal movable plate 104 rotates about the upright rotation shaft 103, the trajectory of the second flange 142 is on a circle centered on the upright rotation shaft 103, but the lock hole 18
1, 182, 183, 184, 185, 186 are arranged on the circle, and the central angle is, when the lock hole 181 is 0 °, the lock holes 182, 183, 184, 185, 18
6 are 90 °, 135 °, 180 °, and 225, respectively.
° and 270 °. Lock holes 181, 182, 18
3, 184, 185, 186 have a lock pin 1
06 slightly larger than the diameter. Therefore, when the second flange 142 comes directly above the lock hole, the lock pin 1
The lower end of the lock pin 106 is fitted into the lock hole 108 because the coil 06 is urged downward by the helical spring 107. When the lock pin 106 is fitted into any of the lock holes 108, the horizontal movable plate 104 is locked and cannot be rotated. To unlock, lock. After manually lifting the pin 106 upward, the horizontal movable plate 104 must be rotated. Therefore, the angle at which the lock hole is arranged, that is, 0 °, 90 °,
The horizontal movable plate can be locked at positions of 135 °, 180 °, 225 °, and 270 °.
