ABSTRACT:
This invention is a leg stretcher with a frame having a seat mounted thereon. A pair of leg platforms are hingedly mounted on opposite sides of the seat with removable hinge pins so that the platforms can be quickly connected and disconnected from the seat. A vertically disposed hydraulic jack is mounted on the frame below the seat. A vertically disposed lift beam is mounted on the hydraulic jack with rollers on the end thereof for engaging a block on the underside of each of the leg platforms so that as the jack raises the beam, the outer ends of the leg platforms will be raised toward a more horizontal position with smooth rolling contact between the wing blocks and the rollers. Elongated handles are connected at one end to the release valve and pump arm of the hydraulic jack with the other ends being disposed adjacent the seat so that the person using the leg stretcher can manipulate the hydraulic jack upwardly and downwardly while sitting on the seat.
