Abstract
Abstract In situ apparatus for exercising in which an operator grips suitable handles and actuates pedals while the angle of the body of the operator relative to a stationary frame varies continuously during each cycle. An upstanding arm is pivotally mounted on the frame. The operator actuated pedals are located on one end of the arm. Suitable linkages connect the pedals with the frame so that actuation of the pedals causes the angle of the arm to vary continuously. This arm supports the user such that when the angle of the arm with respect to the frame varies continuously, the angle of the operator with respect to the frame also varies continuously.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
113 words
Apparatus for physical exercise comprising: a frame; a horizontally disposed rod supported by said frame; an upstanding arm with the lower end thereof supported by said rod for pivotal movement; a shaft carried by said arm intermediate the ends thereof; pedal drive means supported by said arm at the upper end thereof and connected to said shaft for imparting rotation thereto; and first linkage connected at one end thereof to said shaft and connected at the other end thereof to said frame, said first linkage being actuated by the rotation of said shaft for moving said arm about the axis of said rod as said shaft is rotated by said pedal drive means.
Claim 2
Dependent Claim
113 words
Apparatus for physical exercise comprising: a frame; a horizontally disposed rod supported by said frame; an upstanding arm with the lower end thereof supported by said rod for pivotal movement; a shaft carried by said arm intermediate the ends thereof; pedal drive means supported by said arm at the upper end thereof and connected to said shaft for imparting rotation thereto; and first linkage connected at one end thereof to said shaft and connected at the other end thereof to said frame, said first linkage being actuated by the rotation of said shaft for moving said arm about the axis of said rod as said shaft is rotated by said pedal drive means.
Claim 3
Dependent Claim
33 words
Apparatus as claimed in claim 1 and further comprising hand supports on said frame to be gripped by the hands of an operator, said hand supports being spaced apart to accommodate the operator.
Claim 4
Dependent Claim
15 words
Apparatus as claimed in claim 1 wherein said hand supports are fixed to said frame.
Claim 5
Dependent Claim
41 words
Apparatus as claimed in claim 1 and further comprising hand supports with the lower ends thereof supported by said rod for pivotal movement, said hand supports adapted to be gripped by an operator and are spaced apart to accommodate the operator.
Claim 6
Dependent Claim
54 words
Apparatus as claimed in claim 4 wherein said first linkage also is connected to said arm below said shaft and further comprising second linkage interconnecting said shaft, said frame and said hand supports for moving said hand supports about the axis of said rod in response to the activation of said pedal drive means.
Claim 7
Dependent Claim
24 words
Apparatus as claimed in claim 1 wherein said pedal drive means includes at least one chain and sprocket drive arrangement for rotating said shaft.
