By rolling on the surface 3, the moving table 1 is configured to be able to move with a light force in an arbitrary direction. The wheel caster provided on the leg of an ordinary office chair does not move unless a large force is initially applied depending on the moving direction, whereas the ball caster 2 is a spherical ball (resin (Made balls) are rotatably supported, and can be moved in any direction with a light force without requiring a large force.

On the moving table 1 turntable 6 is supported so as to be rotatable in a horizontal plane by interposing the turntable mechanism 5 cyclic. As shown in FIG. 4, the turntable mechanism 5 is provided with a plurality of roller bearings 8 at appropriate intervals in an annular rail 7 fixed to the upper surface of the movable table 1, and the lower surface of the turntable 6 by the roller bearings. For example, a bearing-type turntable commercially available from Osaka Taiyu Co., Ltd. under the trade name “Mawarmini” can be used.

  On the turntable 6, a chair 13 is erected on both sides of the supporting legs 10 a and 10 b, a rear supporting leg 10 c, a seat 11, a backrest 12, and an armrest 12 a. 14 is a side stopper provided on the support legs 10a and 10b on both sides of the chair 13, and the side stopper 14 has a housing 16 fixed to a mounting plate 14a fixed to the outside of the support legs 10a and 10b. A shaft rod 15 is vertically penetrated through the body 16 so as to be slidable in the vertical direction, and a coil spring for biasing the shaft rod 15 upward is provided in the housing 16. An engagement plate 17 is pivotally attached to the mounting plate 14 a at an upper portion of the housing 16, and a compression coil spring 17 a is interposed between the engagement plate 17 and the housing 16 so that the engagement plate 17 faces upward. The shaft rod 15 protruding from the upper portion of the housing 16 is loosely fitted in the through hole formed in the engagement plate 17, and the rubber is attached to the lower end portion of the shaft rod 15 protruding from the lower portion of the housing 16. A pad portion 18 made of metal is fixed, and a handle portion 19 made of rubber is fixed to the upper end portion of the shaft 15. A part of the outer peripheral edge of the turntable 6 is cut into a concave shape so that the pad portion 18 can face the floor surface 3. For this reason, by holding the handle portion 19 by hand and pushing down the shaft 15 and pressing the pad portion 18 down to the floor surface 3, the movable base 1 can be prevented from moving and at the same time the rotational base 6 is prevented from rotating. be able to. In this state, the engagement plate 17 is inclined by the biasing force of the coil spring 17a, and the inner peripheral edge of the through hole of the engagement plate 17 is engaged with the outer periphery of the shaft rod 15, so that the shaft rod 15 is prevented from rising. By maintaining the side stopper 14 in such an operating state, the movable table 1 and the rotating table 6 can be brought into an immobile state. On the other hand, when the side stopper 14 is maintained in the operating state as described above, the engagement plate 17 is pushed down against the elasticity of the coil spring 17a by hand to engage the engagement plate 17 with the shaft rod 15. Since the state is released and the shaft rod 15 is raised by the elasticity of the coil spring provided in the housing 16, the side stopper 14 can be brought into a non-operating state.

  Also, leg rests 20a and 20b are formed below the front edge of the seat 11 of the chair 13 and on the upper surface of the turntable 6 so that both feet of the cared person can be positioned. The footrests 20a and 20b are formed by fixing a linear partition piece 21 and an arcuate partition piece 22 on the upper surface of the turntable 6 so that both feet of the cared person are independently enclosed on the left and right. In addition, by using the ball caster 2 and the turntable mechanism 5, the height of the footrest portions 20a and 20b from the floor surface 3 can be 30 mm or less. Reference numeral 23 denotes a concave notch formed on the outer peripheral edge of the front part of the turntable 6, and the caregiver can position the heel of the foot in the notch so that the rotation of the turntable 6 can be stopped.

  In the transfer assist device configured as described above, for example, when a cared person sitting in a bed is transferred to a wheelchair or when a cared person sitting in a wheelchair is transferred onto a Western-style toilet in a toilet, FIG. As shown in the above, after the caregiver A sits on the seat 11 and sets the side stopper 14 in an activated state to make the chair 13 immovable, the caregiver A has a crotch shape at the front of the chair. Facing the cared person B, both the legs of the cared person A are positioned on the floor 3 and the legs of the cared person B are positioned on the footrests 20a and 20b between the crotch of the cared person A. As shown in FIG. 7, the caregiver A holds the caregiver B by turning both hands of the caregiver A from the armpit to the back of the caregiver B and holds the caregiver B, and the posture of the caregiver A falls back as shown in FIG. Sit on. At this time, both the feet of the cared person B are standing on the footrests 20a and 20b, and the weight of the cared person B is temporarily supported by the standing, so that the physical strength of the cared person A is based on the lever principle. Burden is reduced. The backrest 12 is indispensable for supporting the caregiver A who falls back. The side stopper 14 is inactivated in such a posture as to hold the care recipient B, and the caregiver A kicks the floor surface 3 with his / her foot, thereby rotating the turntable 6 and moving the stand as necessary. 1 is moved horizontally, and a wheelchair, a Western-style toilet, etc. are located behind the care receiver B. The armrest 12a can be safely rotated and moved while preventing the body of the caregiver A from tilting sideways when rotating and moving while holding the care receiver B. And the chair 13 is made immovable again by making the side stopper 14 into an operating state, and the cared person B is fallen on a wheelchair or a Western-style toilet while holding the cared person B. At this time, the caregiver A can stand up according to the principle of the lion by the reaction of the weight that the care receiver B falls backward, so that the physical burden of the caregiver A is not directly applied to the caregiver A. It is reduced.
