ELECTRIC ASSISTING DEVICE

摘要

An electric assisting device for varying the moving speed of a movable object in response to the demand of the user. When a cabinet of an electric suspended closet (10) is moved, a microcomputer (82) derives a target rotational speed from the level of the voltage outputted from a strain sensor (72) provided to a handle part and rotates the rotary shaft of a motor (40) at the target rotational speed by feedback control. In consequence, the arm of the electric suspended closet (10) is rotated to rotate the cabinet. Thus, the lowering or raising of the cabinet by the user is assisted. That is to say, if the load needed to move the cabinet is heavy (the load of the cabinet is heavy or the cabinet is fast moved), the speed of the movement of the cabinet is high, and the assisting force by the motor (40) is strong. Therefore, in response to the demand of the user, the moving speed of the cabinet can be varied.
