Exercise apparatus with adjustable lever arm
DCFirst Claim
1. Exercise apparatus, comprising:
- a vertical support frame;
resistance means on said frame for providing resistance to exercises performed on said apparatus;
an elongate lever arm having a rear end pivotally mounted on said frame for rotation about a first, horizontal axis, and a forward end spaced outwardly from said rear end;
releasable locking means for releasably locking said lever arm in a selected orientation about said first axis;
a first pulley attached to said lever arm for rotation about a second axis adjacent said rear end parallel to and spaced forwardly from said first axis and a second pulley attached to said lever arm adjacent the forward end of said lever arm; and
a cable having a first end linked to said resistance means and a second end, the second end of said cable extending first around at least part of said first pulley and then around at least part of said second pulley for attachment to an exercise device or tie-off.

Abstract
An exercise apparatus having a support frame, an exercise resistance device such as a weight stack, and a linkage such as a cable and pulley linkage extending from the weight stack to various exercise stations, has a lever arm pivotally mounted on the frame for rotation about a first horizontal pivot axis into any one of a plurality of selected orientations relative to the frame, and a locking device for locking the lever arm in the desired orientation. A cable linked to the exercise resistance extends around a first pulley attached to the arm for rotation about a second horizontal axis spaced forwardly from the first and a second pulley at the end of the arm on the lever arm and has a connector at its free end for connecting the cable to a selected exercise device or to a tie-off point. Adjusting the orientation of the lever arm raises and lowers the point of connection to the exercise resistance or tie-off, and allows adjustment for different types of exercises.
