Abstract

PROBLEM TO BE SOLVED: To move easily a person to be cared for at an existing home by performing continuously the operation and the reverse operation of raising the cared for-person through a chest cord by the rotation and rising of a rotating pole and then suspending and moving the cared for-person through a waist cord, with a single actuator. SOLUTION: A horizontal arm 1 is lowered to near the chest of a person to be cared for and a chest cord is hooked onto him. At this time, if possible, the person may hold the horizontal arm in his arms. Subsequently, a motor is started and a rope 12 is wound on a drum 8. Then a swiveling pole 3 is pulled up via a pulley 9 on the upper portion of a fixed pole 4 and continues swiveling. When the pole 3 becomes nearly vertical, the pole 3 compresses a spring 13, hits against a stopper, and stops rotating at a seated position. In addition, when the rope 12 is wound further, an ascending pole 2 ascends by the weight applied to the horizontal arm 1, and suspends the person by a waist cord. When the person is lifted by a fixed amount, the person is moved to a wheelchair. The person is returned by reverse operation. Thus he can be moved easily and safely.

In FIG. 1, a horizontal arm 1 on which a lifting sheet (not shown) is hung has one end fixed to an end of a lifting column 2, the lifting column 2 is slidably inserted into a rotating column 3, and the rotating column 3 has a lower end. , The horizontal arm 1 is maintained horizontal and can be inclined from the vertical by a fixed angle θ, and the fixed support 4 is fixed to the base 5 in parallel with the vertical position of the swivel support 3.
So that it does not fall even if a load is applied,
A caster 6 is provided on the lower surface of each end. A motor 7 with a speed reducer is mounted horizontally below the fixed support 4, a rope winding drum 8 is mounted on an output shaft thereof, and a rope 12 is a pulley 9 above the fixed support 4 and a pulley above the turning support 3. It is stretched via 10 and fixed to the lower end of the lifting column 2.

移動ができる。The nursing operation using the nursing lift will be described below with reference to FIG. As shown in FIG. 2A, the horizontal arm 1 is lowered near the care receiver's chest on the bed,
Multiply by one. At this time, the horizontal arm 1 may be held by the arm if possible. Next, the motor 7 is rotated to rotate the rope 12.
Is wound up on the winding drum 8, the turning column 3 is pulled up via the pulley 9 above the fixed column 4 and continues turning. When the turning column 3 approaches vertical, the spring 13 is compressed and hits a stopper (not shown) to stop turning at the position shown in FIG. When the rope 12 is further entangled, the lifting column 2 which has not been moved due to the weight of the horizontal arm 1 starts to rise. The care receiver should use the waist strap 22
When it is lifted up by the head L, it is completely separated from the bed, as shown in FIG. 2C, and can be moved to a wheelchair or a toilet.

When reaching the position shown in FIG. 2B, the turning column 3 is pushed down by the spring 13 and slightly falls from the vertical direction. When a force component in the turning direction of gravity is generated, the turning column 3 continues turning to the stopper (not shown) and continues turning as shown in FIG. Reach position and stop. At this time, even if the horizontal arm 1 hits the cared person's chest by mistake when the stopper position is set incorrectly, the rope 12 may be loosened.
It is safe without being pressed by the force of.
