Abstract:
PROBLEM TO BE SOLVED: To provide a device for bending and forming a titanium alloy slender material which is smaller in size than a conventional one, uses less heat quantity, and can perform curve-forming of the titanium alloy slender material with a desired curvature and thickness in a short period of time. SOLUTION: The device 10 for bending and forming the titanium alloy slender material includes: a delivering mechanism 14 for intermittently delivering the titanium alloy slender material; a material sandwiching heating mechanism 16 including a pair of sandwiching members 16f, 16m sandwiching a part in a curve processing area of a material 12 delivered by the delivering mechanism from a direction intersecting the longitudinal direction of the material while the delivery of the material is stopped and heating the material to a curve enable temperature; and a material heating curve processing mechanism 18 being adjacent to the heating mechanism, including a pair of curve forming type members 18f, 18m having respectively curve processing surfaces 18P having a curvature with which the part of the curve processing area is curved and heated to the curve enable temperature, and sandwiching the heated part of the curve processing area of the material delivered from the heating mechanism by the curve processing surfaces and allowing it to be along the curve processing surfaces while the delivery of the material is stopped.

Abstract:
PROBLEM TO BE SOLVED: To provide a training machine for a wheelchair user depending on the wheelchair for about 70-80% of a day, especially an aged wheelchair user using the wheelchair for rehabilitation of a bone fracture, capable of preventing the user from becoming bedridden and from suffering the disuse syndrome caused by the bedridden state. SOLUTION: The training machine for the wheelchair user has an actuator 10 driven to extend a driving rod 19, and a slider frame 6 is horizontally raised by using a parallel link mechanism composed of front links 5 and 5 and rear links 7 and 7. With this structure, the seat surface 12 of a sliding chair 11 is raised to the height of transfer to the wheelchair by an electric lift mechanism, so that the seat surface can be stopped at a desired height. Since the seat surface of the sliding chair can be stopped at a desired height in this way, there will be no difference in level in the transfer caused by the difference in the manufacturer or model of the wheelchair 22.
