摘要： PROBLEM TO BE SOLVED: To surely prevent the movement of a device at the time of helping a standing operation by providing a motor-driven movement braking device on an intermediate wheel which is a fixed wheel and performing braking based on electric signals. SOLUTION: A walking operation helping part is composed of front wheels composed of casters provided on front leg parts, rear wheels composed of the casters provided on rear leg parts 3a (3b, not shown in the figure) and the intermediate wheels 11a (11b, not shown in the figure) composed of the fixed wheels provided between the front wheels and the rear wheels. The moving operation braking parts 13a (13b, not shown in the figure) at the time of the standing operation of a user are respectively provided on the rear leg parts 3a (3b, not shown in the figure.) In the moving operation braking part 13a, when a solenoid 18a is operated, a member 19a connected to a straight motion moving part and a wheel abutting rod 16a are moved in a left direction, the wheel abutting rod 16a is abutted to the left intermediate wheel 11a and the rotation of the wheel is stopped by frictional force. When the solenoid 18a is released, the wheel abutting rod 16a is energized by a spring 17a and moved in a right direction from the left intermediate wheel 11a and the wheel becomes rotatable.

摘要： PROBLEM TO BE SOLVED: To provide a self-walking aid device which achieves excellent safety and high versatility along with ease of handling. SOLUTION: A lifting motor 7 of a lifting member is provided with a rotation detecting means 17 to detect and output the number of revolutions of the motor 7. An output value (number of revolutions of the motor 7) of the rotation detecting means 17 is outputted as the current number N of revolutions of the motor to a control means 12 and the control means 12 controls the number of revolutions of the motor 7 based on the current number N of revolutions of the motor. This control regulates the number of revolutions of the motor 7 so that the current number N of revolutions of the motor is almost equal to a set number Ns of revolutions. Thus, the number of revolutions of the motor can be kept constant against changes in the load of the motor 7, especially when a user different in weight uses the device, thereby a lifting speed of the lifting member or the like for assistance from standing action to sitting action can always be kept constant.
