Abstract: A support structure for supporting a portion of a body, the support structure including a support member having a support surface, wherein said support surface is divided into a plurality of pieces; and a mechanism configured to couple said plurality of pieces to each other, said flexible mechanism including: a fixed side member having a first plurality of overlapping plates which are arranged in parallel at intervals; a tilted side member having a second plurality of overlapping plates which alternately overlap on said first overlapping plates of said fixed side member; a coupling shaft which pierces an overlapping position of said first plurality of overlapping plates and said second plurality of overlapping plates to fasten said first plurality of overlapping plates and said second plurality of overlapping plates together, wherein said tilted side member is adapted to rotate around said coupling shaft to impart an angle on the support member.

Abstract: Disclosed is a stretcher with a first shaft that is fixed onto a frame of the stretcher. A second shaft is provided on a head rest. A support arm is installed on the first shaft in a way that it can rotate, and also that supports the second shaft in a way that it can rotate. A rotation prevention member has a being pressed sloped part that receives a pressing force, and a pressing part that is pressed onto the circumference surface of the first shaft or the second shaft, and which can come near to or separate from the first shaft or the second shaft. A wedge shaped member has the pressed sloped part that presses while sliding on the being pressed sloped part of the rotation prevention member, and which presses the rotation prevention member onto the first shaft or the second shaft by the wedge action caused between this press sloped part and the being pressed sloped part.

Abstract: A stretcher capable of transforming into a stretcher configuration and a wheelchair configuration, which increases the rigidity of its frame structure to facilitate retention of a posture of a patient, enhancing safety and is superior in the operability such that transformation is enabled by one operation. A frame of the stretcher is divided into at least four portions, i.e., an above knee portion (4) constituting a seat portion supporting a femoral region of a patient, a lumbar portion (3) included in a backrest supporting an upper portion of a body of the patient, an armrest portion (6) constituting an armrest, and a below knee portion (5) capable of supporting a lower limb region.

Abstract: A rolling walker 1 comprises a first frame 3 supported by a front caster 2 at both ends thereof and a second frame 5 supported by a rear caster 4 at both ends thereof, and a handle 7 provided to either first frame 3 or second frame 5. The first frame 3 and the second frame 5 are foldably connected each other by a connecting shaft 6. The rolling walker 1 has a closed frame fixing means 11 which fixes the first frame 3 and the second frame 5 in a closed position and connects the first frame 3 and the second frame 5 to stand when the first frame 3 and the second frame 5 are rotationally folded around the connecting shaft 6, so that each frame 3, 5 can be kept folded to stand when the rolling walker 1 is not used.

Abstract: A rocking apparatus has a supported member and a supporting member. The supported member rotatably supported on the supporting member at two distant points on a rotary shaft. The rotary shaft is provided with a reaction force imparting member, which is constantly pushed toward its initial position by a reaction force imparting mechanism, so as to be capable of oscillation. A strut is provided between the reaction force imparting member and the supported member, and the supported member is supported on the reaction force imparting member and the rotary shaft by the three-point support using the connecting members and the strut.
