Abstract
Abstract An improved exercise apparatus is disclosed which features a bench mounted on a frame and having rigid rotatable arms mounted at opposing ends of the frame for exercise of groups of leg muscles and arm muscles respectively. Both rotatable members are connected to rotatable disks which have a plurality of attachment points disposed on opposite sides of their axes for connection of a weight bearing member so that the direction of rotation of the disk and of the point at which its rotation starts to do work can be varied whereby a large number of differing exercises can be performed with relatively simple apparatus.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
190 words
Apparatus for the exercise of body members by the lifting of weight against the force of gravity, comprising: a frame; a bench mounted on said frame; a first rotatable arm, mounted for rotation on said frame at an end of said bench to exercise leg muscles; a second rotatable arm mounted on said frame for rotation for exercise of arm muscles; and a weight adapted to be elevated by rotation of either of said first or second arms; wherein means are provided for operative connection of both said arms to said weight, said means for connection permitting variation of the position of said arms at which rotation thereof causes elevation of said weight to commence, and of the direction of rotation of said arms which elevates said weight, said weight being elevated from a rest position upon rotation of one of said arms, said means for connection permitting variation of said rest position with respect to the position of said arms at which rotation thereof causes elevation of said weight to commence, independent of the position of said arm at which maximum effort is exerted against the force of gravity.
Claim 2
Dependent Claim
190 words
Apparatus for the exercise of body members by the lifting of weight against the force of gravity, comprising: a frame; a bench mounted on said frame; a first rotatable arm, mounted for rotation on said frame at an end of said bench to exercise leg muscles; a second rotatable arm mounted on said frame for rotation for exercise of arm muscles; and a weight adapted to be elevated by rotation of either of said first or second arms; wherein means are provided for operative connection of both said arms to said weight, said means for connection permitting variation of the position of said arms at which rotation thereof causes elevation of said weight to commence, and of the direction of rotation of said arms which elevates said weight, said weight being elevated from a rest position upon rotation of one of said arms, said means for connection permitting variation of said rest position with respect to the position of said arms at which rotation thereof causes elevation of said weight to commence, independent of the position of said arm at which maximum effort is exerted against the force of gravity.
Claim 3
Dependent Claim
56 words
The apparatus of claim 1 in which said means for connection permitting variation of the position of said arms at which rotation thereof causes elevation of said weight to commence comprises means mounted for rotation upon exertion of force on said arms, and provided with plural points of attachment to means for elevation of said weight.
Claim 4
Dependent Claim
93 words
The apparatus of claim 1 in which said means for connection permitting variation of the direction of rotation of said arms in which rotation thereof elevates said weight comprises disk means, mounted for rotation by exertion of a force on said arms, and provided with plural points of attachment to means for raising said weight upon rotation of said disk, said plural points being disposed on opposing sides of the axis of rotation of said disk with respect to the points at which rotation of said arms exerts torque on said disk means.
Claim 5
Dependent Claim
24 words
The apparatus of claim 1 including means for varying the distance said weight is raised by a given degree of rotation of said arms.
Claim 6
Dependent Claim
31 words
The apparatus of claim 4 wherein the axis of said second rotatable arm is substantially horizontal, and is furthermore adapted for rotation about a vertical axis with respect to said frame.
