SUBSTANTIALLY CONSTANT-FORCE EXERCISE MACHINE

摘要

A resistance module (10) for an exercise machine (11) for providing a substantially constant force through a range of motion includes at least one cantilever spring (12a, 12j) and at least one rigid member (14b, 80j) movable with respect to one another along a path of travel (P). The rigid member causes the cantilever spring to deflect and produce a resistance force. The rigid member engages a deflection end (18a, 18j) of the cantilever spring, and constrains the deflection end to a predetermined path of deflection as the cantilever spring and the rigid member move with respect to one another. The rigid member can be a non-planer contact surface (14b) along which the deflection end tracks, or a pivot link (80j). The module can include means for operatively coupling at least one of the cantilever spring and the at least one rigid member to an exercise machine.
