Abstract:
A free-standing physical exercise device which can be configured for use in either a knee support mode or in an upstanding mode, both based on a single ground supported frame comprising:(a) a forward first and a rearward second cross member located at the respective longitudinal ends of an elongate rigid member, adapted for conferring stability during operation;(b) a knee support element located intermediate of the longitudinal ends of the elongate rigid member;(c) a substantially rigid, upstanding mast pivotally anchored at its lower longitudinal end to the rigid member at a point intermediate of the knee support element and the forward first cross member;(d) a slidable action mechanism adapted to track and complement the rigid mast, being reciprocally moveable in a slidable manner, so as to engage the mast which then serves as a support means in a plurality of vertical operating positions;(i) means to interruptibly interlock the upstanding mast and action mechanism in any one of the plurality of vertical positions;(e) a dual sidewall, support bracket pivotally anchored proximal to the upper end of the slidable channel action mechanism and extending substantially horizontally therefrom, the bracket provided with one slot-like aperture intermediate the free ends of one of the spaced apart sidewalls;(f) a rigid rod disposed transversely of the dual sidewalls and being movable reciprocally within the one aperture;(g) an elongate lever component projecting rearwardly and interconnecting operatively with support bracket;(h) a plate rigidly engaging the central segment of the lever component proximal to a first rearward edge of the plate;(i) a set of at least three spaced apart, detents provided in the periphery of the opposing forward edge of the plate, which are adapted to receive interruptibly the shaft of the rigid rod;(j) a elongate component projecting rearwardly of the upstanding mast and interconnecting operatively with the support bracket thereof; and,(k) a resistance means aligned in the plane of the rigid member and the associated upstanding mast, being operatively connected at one longitudinal end thereof to the support bracket and with the other longitudinal end of the resistance means being pivotally connected proximal to the lower longitudinal end of the action mechanism;(l) whereby the triple engagement positions as provided by the set of peripheral detents correspond to three distinct juxtapositions for the lever component, and which lever juxtapositions correlate with the several vertical alignments available for the slidable action mechanism.
