An exercise device for use with a support frame as 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.

Why it's free to use
- Filed February 5, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 5, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 5, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
