发明名称 Thigh muscle stretching device
摘要 An improved thigh muscle stretching device includes a central spine or post having a seat bottom on one end thereof, and an elongate worm gear mounted for free rotation adjacent the opposing end of the spine. A movable housing is threadedly received on the worm gear, and a pair of elongate rod members are dual-plane pivotally mounted on opposing sides of the housing. The distal ends of the rod members are adapted for receiving the legs of a user. Rotation of the worm gear is controlled by a multiple-plane pivoting handle positioned for user operation.
