First Claim
Patent Images
1. A weight-lifting apparatus operable by a person for weight training comprising:
- a frame;
a plurality of weights mounted on said frame for generally vertical reciprocal movement from a rest position upwardly against gravity force to an upper position during a lifting stroke, and downwardly from said upper position under said gravity force to said rest position during a negative stroke;
actuating means operable to lift said weights against said gravity force and lower said weights under said gravity force; and
;
means imposing a force in addition to said gravity force of said weights on said actuating means during at least a portion of said downward movement of said weights to provide for restraint of a greater force on the negative stroke than on the lifting stroke.

Abstract
A weight-lifting apparatus operable by a person for weight training. The apparatus has a frame; a plurality of weights mounted on said frame for generally vertical reciprocal movement from a rest position upwardly against gravity force to an upper position, and downwardly from said upper position under said gravity force to said rest position. The apparatus also has a structure for lifting said weights against said gravity force and lowering said weights under said gravity. A resisting force in addition to said gravity force on the weight is applied to said structure during at least a portion of said downward movement of said weights.

8. A weight-lifting apparatus for arm curling exercises for a person'"'"'s arms comprising:
-
a frame; a table for supporting the upper portion of said person'"'"'s arms, said table being pivotal about an axis with respect to said frame; means for locking said table in various fixed angular positions with respect to said frame; a bar mounted for pivotal movement with respect to said frame, said bar including handle means for grasping said bar; and weight means operably connected to said bar and mounted on said frame for generally vertical reciprocal movement from a rest position upwardly against gravity force to an upper position, and downwardly from said upper position under said gravity force to a rest position, said bar being pivotable in one direction to lift the weights and being pivotable in an opposite direction to return said weights, and further including means for adjusting the initial angular position of the bar with respect to the frame. - View Dependent Claims (9)
