Abstract

The present invention has the object of providing a configuration of bed so that the fixed bed frame in rotary-type bed does not disturb care given to a physically handicapped person lying on the bed. A rotary bed frame (6) rotatable around a vertical axis is provided on the fixed bed frame (1) placed on the floor, with a front screen (3) attached to the front side, and a movable mat support member (23) which receives a mat (32) foldably provided, which is divided into a back receiving part, a waist receiving part and a leg receiving part, is provided on this rotary bed frame (6). The rotary bed frame (6) is rotated by an appropriate drive, and at the same time, the back receiving portion (23b) is caused to stand up prior to rotation. Furthermore, the front side portion of the bed frame (1) at least has a transverse width (L) permitting stepping over.

Claims

1. A rotary-type bed comprising a fixed bed frame having front and rear portions, a rotary bed frame disposed intermediate said front and rear portions of said fixed bed frame, means for rotating said rotary bed frame around a vertical axis, a front screen disposed on the front end and supported by a floor surface;

a movable mat support member receiving a mat and being attached to said rotary bed frame, said mat support member including at least a back receiving portion, a waist receiving portion and a leg receiving portion, each of said portions being independently foldable;

a leg receiving mat support receiving a mat for receiving legs provided on the rear end of the fixed bed frame;

a reversely rotatable motor and a screw cylinder attached to a side of said rotary bed frame;

a screw shaft rotatable at a reduced speed by the motor engaging said screw cylinder;

a rotation mechanism for rotating the rotary bed frame by about 90°

relative to movement of the screw cylinder and an interlocking mechanism operative to effect sequential folding of the back receiving portion, the waist receiving portion and the leg receiving portion, said rotation mechanism and said interlocking mechanisms being both disposed between the screw cylinder and the fixed bed frame, and said interlocking mechanism including means operative prior to starting rotation of the rotary bed frame and simultaneously with raising of the back receiving portion, to raise the leg receiving portion sufficiently to avoid the mat for receiving legs, and at least the front portion of the bed frame having a narrow width sufficient to permit stepping over.
