Abstract
Abstract Exercise apparatus is described incorporating a combination of adjustable leg and arm exercising features. Mounted on one end of a table is a pivotal leg exerciser which is engaged by the ankle and pivoted against an adjustable spring force. Mounted on the sides of the table are hand grips attached by cables to adjustable springs for exercising the arms, shoulders and chest. Mounted above the table is a bar which is to be pressed up with the legs against the force of an adjustable spring. This bar may be pivoted downwardly from its normal leg exercising position to a lowered position for pressing with the arms. The hand grips are attached to the bar to provide the resisting force in this lowered position. In either the raised or lowered position the bar is supported so that it cannot accidentally fall on the person exercising.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
124 words
Muscle-exercising apparatus comprising: a. a table including a table top; b. support means attached to each of the two sides of said table, each of said support means extending in a generally vertical direction and extending above said table top; c. a bar supported above said table top across the upper ends of said support means and movable with respect thereto, d. restraining means limiting movement of said bar to the plane of the support means; e. resilient tensioning means attached to said bar; f. anchoring means anchoring said resilient tensioning means so as to exert a downward force on said bar whereby said bar may be pushed upwardly by the user from said support means against the force of said resilient tensioning means.
Claim 2
Dependent Claim
124 words
Muscle-exercising apparatus comprising: a. a table including a table top; b. support means attached to each of the two sides of said table, each of said support means extending in a generally vertical direction and extending above said table top; c. a bar supported above said table top across the upper ends of said support means and movable with respect thereto, d. restraining means limiting movement of said bar to the plane of the support means; e. resilient tensioning means attached to said bar; f. anchoring means anchoring said resilient tensioning means so as to exert a downward force on said bar whereby said bar may be pushed upwardly by the user from said support means against the force of said resilient tensioning means.
Claim 3
Dependent Claim
45 words
Muscle-exercising apparatus as recited in claim 1 wherein said support means comprise hollow supports, said restraining means comprise rods attached to said bar and extending downwardly into said hollow supports and wherein said resilient means comprise springs attached to the lower ends of said rods.
Claim 4
Dependent Claim
25 words
Muscle-exercising apparatus as recited in claim 2 wherein said anchoring means include means for varying the anchor position so as to vary the spring force.
Claim 5
Dependent Claim
46 words
Muscle-exercising apparatus as recited in claim 1 wherein said support means is hinged at a point above said table top whereby said support means may be folded down to a generally horizontal position in which said bar may be pressed by the arms of the user.
Claim 6
Dependent Claim
92 words
Muscle-exercising apparatus as recited in claim 4 and further including a hand grip support on each side of said table, a hand grip mounted on each support, additional resilient tensioning means, flexible strands attaching said hand grips to said additional resilient tensioning means whereby said hand grips may be used for exercising the arms and further including means for attaching said hand grips to said bar when said support means is folded to the generally horizontal position and permitting said additional resilient tensioning means to provide a downward force on said bar.
Claim 7
Dependent Claim
37 words
Muscle-exercising apparatus as recited in claim 5 wherein said additional resilient tensioning means comprises separate springs for each of said hand grips and further including means for separately adjusting the tension on each of said separate springs.
Claim 8
Dependent Claim
39 words
Muscle-exercising apparatus as recited in claim 6 and further including rests mounted on said table and positioned so as to support said bar above said table top a predetermined distance above the user when said support means are folded.
Claim 9
Dependent Claim
132 words
Muscle-exercising apparatus as recited in claim 7 and further including additional leg exercising apparatus at one end of said table comprising brackets attached to said table, a pivot shaft attached between said brackets, two arms pivotally mounted on said shaft and fixed with respect to each other, one of said arms having a rest position extending generally horizontally outwardly from said table and the other of said arms having a rest position extending generally downwardly from said shaft, adjustable resilient tensioning means attached to said other arm so as to vary the resistance of pivotal movement of said arms about said shaft, and a crossbar attached at right angles to each of said arms, said crossbar adapted to be engaged by the exerciser to pivot said crossbar and arms about said shaft.
