Abstract: A hip reciprocating apparatus of a reciprocating gait brace provides for transfer of forces from movement of one leg to a reverse movement of the other leg of a user. A C-shaped pivot member pivots about a horizontal axis and is mounted at the back of the pelvic band of a gait brace. The pivot member ends are adjacent hip joints which couple the pelvic band to a leg or lower hip joint member. A length-adjustable tie rod couples the pivot member ends to posteriorly extending protrusions of the associated leg member. The pivot point of the pivot member may be equally or unequally spaced relative to the pivot member ends. The leg member protrusions may be of different lengths. A spring may be used to store energy during pivoting of the pivot member in one direction and release of the energy during pivoting in the other direction. An external power source may apply energy to movement of the pivot member in both directions.

Abstract: A mobile arm, chest, and shoulder exercise apparatus to be used to train and condition participants in sports demanding a high degree of arm speed, endurance, and power. A harness which conforms to the user's upper back and sides and provides a path for elastic cords through a system of pulleys to a position adjacent the user's armpits, where hand grips are attached to the ends of the eleastic cords. When the user grasps the hand grips and directs them away from the harness, the resistive force of the elastic cords is transferred to the user's arms, thereby providing a relatively constant resistive force directed toward the armpits for strengthening the arms, chest, and shoulders. Generation of a nearly constant force is accomplished by directing one or more of the elastic cords to the rear of the apparatus, thereby allowing for the use of an increased length of cord. The apparatus may be adjusted to fit the physical dimensions of the user, and the resistive force may be varied to fit the needs of the user.
