Abstract:
A resistance mechanism for a resistive exercise machine, comprising:a plurality of resistance packs arranged in a stack which includes a plurality of pairs of resistance packs, each resistance pack having a substantially circular rim and a central hub connected with said rim by a plurality of resistance elements acting to resist turning of the rim of each resistance pack relative to the hub thereof;a rim connection connecting the rims of the resistance packs in each pair thereof, the hubs of the resistance packs in each pair being rotatable relative to one another;a hub connection connecting the hub of one resistance pack in each pair thereof with the hub of one resistance pack in each adjacent pair of resistance packs, the rims of the resistance packs in different pairs which are adjacent being rotatable relative to one another; andan actuator element coupled with a selected one of said resistance packs, said actuator element being accessible for manual displacement thereof in a manner to effect relative rotation between the rims and hubs of the resistance packs, with said resistance elements resisting such relative rotation to provide a resistive force opposing displacement of said resistance element.
