  • Exercise device
    Patent number: 6503175
    Abstract: An exercise device for use with a support frame is disclosed. The device includes a pair of spaced clamp members each having a body portion terminating in first and second edges. A length-adjustable attachment member interconnects the clamp members, and a grip element is associated with the attachment member intermediate the clamp members. A leverage mechanism is operatively connected to the clamp members so that when the clamp member first edges are supported on a frame, the leverage mechanism urges the clamp member second edges laterally inwardly against the support frame in response to a downward force exerted on the grip element.
