  • Patent number: 5681247
    Abstract: An exercise device has a support frame and a lever arm attached to the support frame and pivotably movable between a rest position, wherein the lever arm hangs downwardly relative to the support frame, and an extended position, wherein the lever arm is pivoted upwardly from its rest position. A range of motion (ROM) block is rigidly attached to the lever arm, and pivots with the lever arm. The orientation of the ROM block relative to the lever arm can be selectively varied.A tackle is attached to the ROM block to provide an opposing force to motion of the lever arm from the rest position to the extended position. This tackle includes two pulleys that are attached to the ROM block. The tackle also includes a substantially taut cable that extends between the pulleys, and the cable is connected to a mass.

  • Patent number: 5674167
    Abstract: A strength training exercise apparatus includes a frame having an upright back rest, and a horizontal seat, and further includes opposing arm members pivotally mounted to the back rest. The arm members are movable through an arcuate range of motion, and include locking pins for selectively locking the arm members in desired angular positions. The apparatus still further includes a resistance assembly consisting of a fixed anchor mounted on the frame, a movable anchor which is movable relative to the fixed anchor, and a plurality of elastomeric resistance cords releasably secured between the movable anchor and the fixed anchor to provide resistance to movement of the movable anchor. A pull line is mounted on guide pulleys along the length of the arm members, and is received in association with the movable anchor whereby outward movement of the pull line with respect to the arm members causes movement of the movable anchor with respect to the fixed anchor.

  • Patent number: 5667464
    Abstract: An apparatus and a method for performing a shoulder press exercise are disclosed. A user support and a primary hinge are mounted to a frame. A secondary hinge is mounted to the primary hinge. An arm mounted to the secondary hinge has a handle adapted to be grasped by the user. The two hinges permit the user to displace the handle in either or both the longitudinal and lateral directions. A means for resisting the displacement of the handle, preferably in both the lateral and longitudinal directions, is provided. The resistance means may include a post attached to the arm for mounting weight plates. A second handle, arm, and secondary hinge may be provided for the other hand so that the user may exercise both halves of his body. The arms may be connected such that both handles move the same longitudinal and/or lateral distance.

  • Patent number: 5658223
    Abstract: A longitudinal frame supports a seat whose longitudinal position on the frame is adjustable. A pair of footbeams are mounted on either side of the forward end of the frame near the floor and extend generally upwardly. The footbeams independently pivot on the frame so that the user can operate them in an alternating reciprocating fashion. Pivotal movement of the footbeams by the user is resisted, thereby requiring the user to expend energy in operating the device. The footbeams are preferably interconnected so that their respective movements am coordinated. In alternative embodiments, the footbeams pivot about a point just below the seat. The seat can also be adapted to recline, preferably at an angle greater than 30.degree. from the vertical. The footbeams can also be replaced by a crank with footpedals that are used to drive a flywheel and a generator.

  • Patent number: 5628715
    Abstract: An apparatus and a method for performing a squat press exercise are disclosed. A user support, such as a seat and a backrest, is mounted to a frame. A four-bar linkage is mounted to the frame distal to the user support. A footplate is mounted to the four-bar linkage. A lever is mounted to the four-bar linkage and is adapted to support removable weight plates. As the user presses the footplate, the four-bar linkage rotates, controlling the orientation of the footplate such that the footplate does not rotate with respect to the user support (and, thus, the user). The lever also rotates, causing the weight plates to lift in an arcuate path, thereby providing an increasing resistance to the movement of the footplate during the concentric portion of the exercise. In accord with another aspect of the invention, a method is provided for exercising the legs and lower torso. A weight resistance is selected. A user is supported on a user support and places her feet on a footplate.

    Abstract: A lower-body exercise machine is provided having a frame, a carriage assembly pivotally attached to the frame and moveable in an upwardly and downwardly arcuate path about the frame, a support beam attached to and extending upwardly from the frame, and a platform pivotally attached to the frame and angling downwardly. A hookbar assembly is pivotally attached to the carriage assembly for releasably engaging the support beam to arrest the downward motion of the carriage assembly. The hookbar assembly comprises a hook bar rotatably attached to the carriage assembly, an elongated hook attached to and extending upwardly from the hook bar, and an elongated engagement handle attached to the hook bar. A rung is attached to the support beam. By moving the engagement handle upwardly, the hook bar rotates and pivots the hook towards the support beam to engage the rung and arrest the downward movement of the carriage assembly.
