In this embodiment, a semicircular plate 15 is provided near the center of each of the longitudinal edges of the bed 1, and four grooves 16 are formed on the outer periphery of the plate 15 so as to open in an L shape. The rotation shafts 5 and 6 are rotatably supported below the plate, and the two ends of the rotation shafts 5 and 6 are located at a position slightly from the center of the end of the arm 2 with the arms 2 facing each other. Connect them together. A horizontal rod 20 protruding toward the opposite arm 2 is provided at the tip of each arm 2, and the horizontal rod 20 is soft and has a knee rest with a restoring force that restores the original state when the external force disappears. The body 3 is attached. Further, the forward end portion of the arm 2 is horizontally rotatable at a position advanced in the horizontal direction from the mounting position of the arm 2 mounted on the rotary shafts 5 and 6. Further, the two arms 2 are provided with two handles 10 in the outward direction with the rotating shafts 5 and 6 interposed therebetween. A gear 14 is provided at the center of the rotating shafts 5 and 6 as a driving device, and the gear 14 and the motors 7 and 8 provided on the back surface of the bed 1 in the longitudinal direction are connected via a chain 9 to the motor 7 , 8 rotates the arm 2 in the upward and downward directions by driving the rotating mechanism. Further, the driving of the motors 7 and 8 is performed by operating the operation unit 13 arranged at the bedside of the bed 1, and the control unit 4 controls the motors 7 and 8 to interlock or individually rotate forward / backward / stop. To do. As a holder for holding the angle of the arm 2 at a required angle, an opening 18 is provided in the arm 2 that is in contact with the plate 15, and the L-shaped locking piece 17 is partially exposed from the opening 18. It is inserted into the arm 2 and the spring 19 allows the L-shaped locking piece 17 to slide in the opening 18 of the arm 2.

In the present embodiment, the sick person 11 who cannot raise his knees by himself is placed so that the abdomen of the sick person comes near the attachment position of the pair of opposing arms 2 provided on the peripheral edge of the bed 1 in the longitudinal direction. The sick person 11 is lying on the bed 1. In the present embodiment, when the sick person 11 is lying on the bed 1, as shown in FIG. 7, the pair of arms 2 are rotated so as to be substantially parallel to the longitudinal edge of the bed 1, The knee support 3 is placed between the bed 1 and the vicinity of the back of the sick person's knees, but when the sick person 11 sleeps on the bed 1, the knee support 3 and the arm 2 are not obstructed.

As shown in FIG. 8, when raising the knees of the sick person 11 when changing the diaper of the sick person 11 and performing defecation, the nurse operates the operation unit 13 at the bedside of the bed.
