Abstract
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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
231 words
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.
Claim 2
Dependent Claim
231 words
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.
Claim 3
Dependent Claim
44 words
An exercise apparatus for physical therapy, muscle rehabilitation and the like in accordance with claim 1, wherein said first and second peg-support members each includes means for mounting the associated one of said pegs at a selectable distance from the axis of rotation thereof.
Claim 4
Dependent Claim
50 words
An exercise apparatus for physical therapy, muscle rehabilitation and the like in accordance with claim 1, wherein said first and second peg-support members each includes means for mounting the associated one of said pegs at a selectable angular position with respect to the rotational position of said rotary peg-support member.
Claim 5
Dependent Claim
40 words
An exercise apparatus for physical therapy, muscle rehabilitation and the like in accordance with claim 1, wherein said respective horizontal axes of rotation of said first and second peg-support members are in alignment, constituting a common axis of rotation therefor.
Claim 6
Dependent Claim
35 words
An exercise apparatus for physical therapy, muscle rehabilitation and the like in accordance with claim 1, wherein said mechanical drive means effects simultaneous rotation of said first and second peg-support members at a common speed.
Claim 7
Dependent Claim
33 words
An exercise apparatus for physical therapy, muscle rehabilitation and the like in accordance with claim 5, and including speed-control means for selectively varying said common speed of rotation of said two peg-support members.
Claim 8
Dependent Claim
40 words
An exercise apparatus for physical therapy, muscle rehabilitation and the like in accordance with claim 1, and including a patient-support member connected to said stationary support frame for supporting the patient at a position of access to said peg-support members.
Claim 9
Dependent Claim
29 words
An exercise apparatus for physical therapy, muscle rehabilitation and the like in accordance with claim 7, wherein said patient-support member is selectively adjustable relative to said stationary support frame.
Claim 10
Dependent Claim
105 words
An exercise apparatus for physical therapy, muscle rehabilitation and the like in accordance with claim 1, and including a second adjustable support frame mounted on said stationary support frame below said first adjustable support frame and in substantial vertical alignment therewith, said second adjustable support frame including third and fourth support arms each pivotally mounted on a respective one of said side frame members for movement in respective planes each parallel to said side frame members, and second cross-arm means fixedly attached to and interconnecting said third and fourth support arms for maintaining the latter in parallel relationship for all positions of said pivotal movement.
