Abstract: A hand truck having load shifting member which tilts the hand truck under conditions of greater leverage than that available by grasping the frame of the hand truck is disclosed. The load shifting member comprises a spring retracting lever rotatably attached to an axle journaled from the frame of the hand truck such that when in a retracted position, the lever is substantially parallel to the frame. Pulling on the upper end of the lever rotates the lever such that the lower end of the lever engages the lower portion of the hand truck frame, shifting the center of gravity of the loaded hand truck such that it may be more easily tilted to a position for moving the hand truck. A spring returns the lever to a retracted position when not in use.

Abstract: An exercise apparatus particularly designed to strengthen the gluteus and hamstring muscles is disclosed. A pivot arm includes a weight arm which can be loaded with weights as desired. The pivot arm pivots in a longitudinal direction at one side of the base of the apparatus. The pivot arm includes a paddled hip engagement bar which extends over the base. A handhold member is mounted to the base and is pivotable at a right angle to the pivot movement of the pivot arm. A latching on the pivot arm can engage a catch on the handhold member when the apparatus to be placed is in a parked position.

Abstract: A grasping tool for a corner of a box or carton includes a pair of plates joined at a hinge element which is spring loaded to cause the plates to return to a rest position. A lever is fixed to each plate such that the levers may separate the plates about the hinge axis against the load of the spring of the hinge. Each plate includes tangs which will penetrate the outer skin of a carton to which the grasping tool is to be temporarily fixed.

Abstract: A weight lifting simulator exercises the hip girdle and shoulder girdle. A user standing on an inclined foot plate grabs a pair of handles which are free to swivel and raises a head member which slides along an upright mast which is slightly inclined toward the user positioned on the foot plate.

Abstract: Exercise apparatus for strengthening the triceps, deltoid and pectoral muscles. A moveable yoke is dual hinged to an upright support mounted to a base. The yoke has a pair of spaced apart levers each perpendicularly fixed to a weight moment arm. Free weights may be attached to the weight moment arms. The yoke may be rotated about a vertical axis over a limited non-symmetrical range from a park position to an operating position. The yoke is also pivotable about a horizontal axis in the operating position. A seat and back rest are supported on the base spaced apart from the upright support.

Abstract: Exercise apparatus for the calf muscles of the legs includes a foot platform which may rock forward and rearward on the base of the apparatus. A lateral arm is supported above the base and has spaced shoulder engagement arms which overlie the foot platform. The lateral arm is raised and lowered by the action of a user rocking back and forth on the foot platform. The lateral arm is linked to a weight arm which is raised and lowered with the movement of the lateral arm. Free circular weight plates can be suspended on the weight arms.

Abstract: A hand truck having ground engaging members which tilt the hand truck under conditions of greater leverage than that available by grasping the frame of the hand truck. The ground engaging members are journaled to the frame of the hand truck. In one embodiment, the ground engaging members assume the entire weight of the loaded hand truck. In another embodiment, the ground engaging members push the front end of the hand truck upwardly, employing the wheels as a fulcrum. In the second embodiment, the wheels remain in contact with the ground. In the first embodiment, the ground engaging members serve also as a fulcrum, allowing the wheels to be elevated off the ground. In both embodiments, the ground engaging members are powered either by a foot operated lever or a hand operated lever. In the first embodiment, the foot or hand operated lever is rigidly fixed to the ground engaging members. In the second embodiment, the foot or hand operated lever is a separate part which moves flippers by a multipart linkage.
