PROBLEM TO BE SOLVED: To provide a subsidiary chair for a standing worker which has a saddle 1 always following and giving upward power to the lower back of the standing worker who moves three-dimensionally, and which reduces the burden of the worker's leg. SOLUTION: The subsidiary chair for a standing worker comprises a moving mechanism 5 which rotates and moves on a floor surface, a moving board 4 having the moving mechanism 5, an upward mechanism 2 using a gas spring 31 using the pressure of the gas sealed up in a tube as a power source at the upper part of the moving board 4, and a saddle 1 at the upper part of a movable part which operates by the motion of the gas spring 31. It always gives the upward power to the hip of a worker who sits on the saddle 1. COPYRIGHT: (C)2008,JPO&INPIT |
