US Patent:

7491159, Feb 17, 2009

Filed:

Jul 30, 2004

Appl. No.:

10/903204

Inventors:

Gary W. Patterson - Denver CO, US

International Classification:

A63B 21/008

US Classification:

482112, 482137

Abstract:

A resistance assembly for a hydraulic resistance exercise apparatus includes a single-action hydraulic cylinder having a longitudinal axis and extending from a first end to a second end. The single-action cylinder provides resistance to compression of the cylinder, one end toward the other, but provides little or no resistance to extension of the cylinder, one end away from the other. A first compression linkage compresses the hydraulic cylinder in response to movement of a first exercise resistance lever in a first direction. A second compression linkage compresses the hydraulic cylinder in response to movement of a second exercise resistance lever in a second direction directly opposed to the first direction. An engagement exercise lever includes an engagement pin for selectively engaging the engagement exercise lever to move in fixed relation to one or the other the first or second exercise levers in both the first and second direction.

Abstract:

An exercise apparatus (10) includes a hydraulic resistance member (50) with a single sided hydraulic cylinder (53) for pumping fluid through a fluid circuit (80). Lever members (31, 32) pivot in a common plane and extend outward to embrace the hydraulic resistance member (50) between them. Stop members (221,223) limit movement of the lever members (31, 32), and biasing member (230) biases 10 the lever members (31,32) apart. An immobilizing member (40) may selectively immobilize either one of the lever members (31, 32). An extension arm (17) supports an exercise member (16) which may move along an exercise stroke only by pumping cylinder (53). The fluid circuit (80) allows fluid to flow from the cylinder (53) only when pressure in the cylinder (53) exceeds a selected pressure corresponding to a selected exercising force determined in accordance with the position of the member (16) along the exercise stroke by a control linkage (100). During the return stroke, no exercising force is required.
