发明名称 RETRACTABLE WINDING MECHANISM FOR ELASTIC MOTORS
摘要 A winding mechanism for an elastic motor includes a manually actuatable winding element for rotating a rotatable member connectable to the elastic motor, a one-way drive device for transmitting drive in a first direction from the winding element to the rotatable member but not in the reverse direction to the first direction and including means for preventing reverse rotation of the rotatable member and means for automatically returning the winding element into its initial position after it has been moved in the first direction.
