Abstract
A multiple purpose exercise device has a stable ground-supported frame having a single structural rail extending vertically at the rear thereof. A series of vertically aligned holes in a flange attached to the rail receive fastening pins for separately adjustably securing an exercise bench and a lever arm. The lever arm may be secured in a rigid position or in an upwardly or downwardly biased position by an interchangeable series of rigid connecting bars and spring members to allow the user to perform various pushing and pulling exercises.
Claims8
Multiple purpose exercise apparatus comprising:
- a frame having forward and rearward positions comprising a ground-supported base and a stationary vertical support member extending upwardly from the rear of the base,
- a bench, support means associated with said frame for maintaining the bench at a level above the base,
- a lever arm pivotally attached to said vertical support member and extending outwardly over said base, fastening means for securing the lever arm to the support member comprising a plurality of vertically aligned bores in the support member, a transverse bore carried by the rearward portion of the lever arm, and pin means extending through both bores for removably pivotally attaching the lever arm to the vertical support member such that the lever arm can move freely only in a vertical plane, biasing means attachable to the lever arm at a position spaced from the connection of the lever arm on the vertical support member for selectively providing resistance to upward or downward motion of the lever arm in the vertical plane, and
- attachment means mountable in the vertically aligned bores for selectively attaching the biasing means at various position on the vertical support member.
