2. Description of the Related Art The presence of a caregiver is indispensable for patients who have been bedridden for a long time in beds for home use, hospital beds, seriously ill patients, and elderly people. In particular, when transferring to a wheelchair, or carrying the patient's body to a toilet near the bed, the caregiver moves the patient to the side of the floor and transfers to the wheelchair while supporting the patient's body. I had to give it away. At that time, depending on the patient's condition, the caregiver may have to carry the patient on his back, and the caregiver was forced to make a great deal of effort. Therefore, various lift devices for dynamically lifting a patient have been proposed. As such a lifting device, for example, a moving type or a ceiling hanging type can be cited.

[0003]

However, since the bed for home use is often arranged in a Japanese-style room, the caster sinks in the tatami when moving, which makes it very difficult to use and stable. It lacks and is unsuitable.
On the other hand, in a ceiling-suspended device, the strength of the ceiling is a problem. In particular, since the Japanese-style room is made up of wooden beams and ceiling boards, it is impossible to suspend the patient without suspending it from a thick cross beam. Therefore, the arrangement position of the bed is limited. Otherwise, it is necessary to provide a reinforcing frame or the like for special hoisting, which increases the equipment cost. An object of the present invention is to provide a bed-mounted electric care lift in which a lift means for lifting and lowering a patient is fixed to a bed.

Next, referring to FIG. 5, another embodiment of the bed-mounted electric care lift according to the present invention will be described. In the present embodiment, the electric nursing care lift 2 described above is used.
The same components as those constituting the above are designated by the same reference numerals. In this embodiment, the base frame 23 constituting the electric care lift 22 is attached to the fence receiving hole (described later) of the side frame 21 from above the side frame 21 of the bed 20. That is, a vertical frame 24 is provided on the base frame 23, and a rotary column 8 is rotatably provided on the vertical frame 24. A lifting arm 9 is movably connected to the rotary column 8 so that the rotary column 8 can be lifted. The electric actuator 10 for expanding and contracting is connected between the suspension arm 9 and the suspension arm 9 to drive the suspension arm 9 up and down. A control box 25 for operating the electric actuator 10 is mounted on the rear side of the mounting position of the electric actuator 10 on the pivot column 8. And
