Abstract
An adjustable multi-function exercise apparatus having a base and a pair of rigid spaced interconnected upstanding support "A" frames for pivotally positioning a longitudinal frame a fixed distance from the base; the pivotal long frame and upstanding supporting "A" frames being so designed as to provide for adjustable positioning of the pivotal frame to a desired fixed position. The longitudinal frame being open at one end for a pair of spaced rotatable plates. The plates are diagonally, multi-apertured for selectively receiving hand grips. The spaced rotatable plates are selectively driven by a variable speed drive, permitting variable multiple functional use of the exercising apparatus.
Claims9
An exercise apparatus for physical therapy, muscle rehabilitation and the like, comprising:
- a rigid stationary support frame including a pair of substantially parallel spaced-apart A-frame side members between which a patient may stand or sit when operating the machine,
- a substantially U-shaped pivotal support frame mounted on said stationary support frame medially of said pivotal frame and having means thereon for positively locking said pivotal support frame in a selectable fixed pivotal condition with respect to said stationary support frame, said pivotal support frame including first and second parallel lateral support arms each pivotally mounted at the top of a respective one of said side frame members, and cross-arm means fixedly attached between the open set of proximate ends thereof and interconnecting said support arms for forming a rigid open box for maintaining the support arms in parallel relationship for all positions of said pivotal movement,
- first and second peg-support members mounted respectively on said first and second support arms for rotation about respective horizontal axes,
- first and second pegs mounted respectively on said first and second peg-support members at a position spaced from said respective horizontal axes, each said peg extending in a horizontal orientation,
- an electric motor having a rotary output shaft, and
- mechanical drive means interconnecting said motor output shaft and each of said first and second rotary peg-support members for effecting rotation of each of the latter.
