Abstract: A crutch is provided which is specifically designed for use by people who are overweight, or have scoliosis (a curvature of the spine condition), there being an S-curve defined in the upper portion of the crutch so that the crutch will comfortably fit into the underarm and yet bend out and continue downward spaced further out laterally from the body so that the hip of an overweight person or a person with scoliosis is detoured by the crutch. The crutch is made hinged and collapsible so that it is easier to store and transport to offset the slightly more cumbersome shape of the crutch because of the incorporation of the S-curve. The crutch also features three point adjustability so that the overall length of the crutch, and its length between the S-curve and underarm support, and between the handgrip and the ground and the handgrip and the underarm are independently adjustable.

Abstract: The invention comprises a retrieving instrument featuring a snap-lock handle connected to one end of a flexible cable, the other end of which has a releasible gripping head which may be mechanically or electromagnetically operated, there being an actuation control mechanism which locks the jaw in either the gripping mode or the release mode until the control is changed. A viewing system utilizing newly developed fiber optic techniques is preferably incorporated into the structure.

Abstract: The invention comprises a retrieving instrument featuring a snap-lock handle connected to one end of a Bowden wire type cable, the other end of which has a gripping head with jaws operated by the core cable to grip an object, the handle being such that once it is closed and the jaws gripped around an object, they automatically lock into the gripping mode until released.
