Claims

[Scope of Claim for Utility Model Registration] One side edge of a fixed base and a movable base are bent and connected freely at the center, the other edge of the fixed base is attached to a base frame fixed to the floor, and the other edge of the movable base is attached to a wheel. In a folding stage set in which each pivot is attached to a foot stand provided with the stand, and both stands are folded into an upright position from the central connecting part, an upper end is located below the connecting part. A pair of bent arm pieces are attached to the shaft so that they can rotate freely, and can be bent into a dogleg shape in the middle of the length, and the lower ends are connected together by the shaft to form a pantograph shape, and the lower ends are connected. A wheel and a lower pulley are provided at the part, and a pair of upper pulleys are provided opposite to the bent parts of the bent arms,
The wire fed out from the wire winding device provided in the base frame is hung on the lower pulley, then passed from one upper pulley to the other upper pulley, and again to the lower pulley to make a loop, and then wrapped around the footrest side. The folding arm piece is placed on a folding pulley prepared for the above-mentioned operation, and the end thereof is fixed to the base frame by passing it under the lower pulley again, and by the wire winding operation of the winding device, both upper pulleys are pulled together, and both bent arm pieces are extended. A stage set in which the fixed base and movable base connection parts are pushed up, and then the folding pulley is pulled toward the base frame and folded into two.
