Abstract:
Apparatus for bi-directional ankle exercise movements has a main-frame with a seat and upwardly extending columns at either side to support a “U” shaped sub-frame, mounted so that it pivots about a horizontal axis passing very nearly through the ankles of a seated user and interconnecting linkages simultaneously enforcing ankle inversion, with plantarflexion and then ankle eversion, with dorsiflexion, about perpendicularly intersecting axes, while resisting such movements, so as to provide bidirectional ankle exercises according to a progressive resistance program, thus strengthening the ankle muscle groups for enhanced balance and dynamic stability.
Abstract:
A method and apparatus for bi-directional exercising of upper body muscle groups including the steps of mounting lever arms for pivotal movement about primary and secondary axes; arranging the axes so that they are essentially perpendicular and intersect at a shoulder of a user, wherein the user exercises by grasping the lever arms and pivoting each of them independently about both axes simultaneously moving them close together from an extended position, with resistance opposing such exercise movements.
Abstract:
A compact weight lifting machine includes a lift bar assembly including a lift cable and a lift bar which operates through the lift cable to lift selected weights from a weight stack responsive to either upward or downward movement of the lift bar. A seat assembly is positioned beneath the lift bar and includes first and second sections selectively positionable to support a user to perform a variety of exercises. A leg extension/leg curl mechanism located at one end of the seat assembly and a butterfly mechanism located at the opposite end of the seat assembly also operate through the lift cable to lift selected weights from the weight stack.
Abstract:
Apparatus for bi-directional torso exercise movements has a main-frame base with a seat and upwardly extending columns at either side to support a “U” shaped first sub-frame, mounted so that it pivots about a horizontal first axis passing above the seat, and a second sub-frame mounted to the first sub-frame cross bar for pivotal movement about a second axis generally perpendicular to the horizontal first axis and thereby, mounted for pivotal movement about both axes. A motion transfer linkage is provided to force simultaneous pivotal movement of both sub-frames when either is moved, so as to involve compound muscle groups in an exercise movement.
Abstract:
An exercise device includes forced pronation or supination movement of the hands and arms in conjunction with the standard range of motion for a specified exercise. The device comprises a conventional frame and a centrally mounted seat. Pivotally attached to the frame is a sub-frame including a pair of levers that pivot in tandem about a first horizontal axis of rotation A1 and movably attached to the distal end of each lever is a double “L” shaped handle that includes a grip that pivots about a second axis of rotation A2. A2 is substantially perpendicular to A1 and the second leg of the double “L” shaped handle is movably attached with a ball and socket connection to a first end of a linkage rod. The second end of the linkage rod is movably attached with a second ball and socket connection to the frame.

Abstract:
A weight lifting machine for performing a wide range of exercises, has a lift bar angularly adjustable for a starting lift position angularly upward or downward of a substantially horizontal position. An actuating bar is connected to the lift bar for movement therewith. First and second pulleys are movably mounted above and below the actuating bar such that the first pulley moves upwardly with the actuating bar and the second pulley moves downwardly with the actuating bar. The first pulley is prevented from moving downwardly when the second pulley is moved downwardly with the actuating bar and the second pulley is likewise prevented from moving upwardly when the first pulley is moved upwardly. A lift cable is threaded through the first and second pulleys such that movement of the lift bar in either direction lengthens the distance between the pulleys, thereby lifting a plate-type weight stack. The machine is also equipped with butterfly bars and a leg extension, with the lift bar, butterfly bars and leg extension all connected to the weight stack through a single lift cable.
