Abstract
Abstract An apparatus for exercising the calf muscles defined by a framework in which a top extremity thereof is provided with a pair of horizontally extending arms pivoted to a pair of top frame members interconnected and capable of rotation, shoulder pads disposed on the bottom face of these rods at extremities remote from the pivot point, a rigidifying cross brace provided with an opening through which a vertically extending rod is adjustably pinned. This rod traverses through a plurality of weights whose magnitude is selectable and substantially beneath the shoulder pads there is provided on the floor a toe support so that one's toes while standing thereon allows the heel to extend out into space. The exercise is performed by flexing the arch and standing on one's toes which provides tension to the calf muscle.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
196 words
A standing calf machine comprising a base framework, a pair of vertically upstanding rod members extending from and supported by one end of said base framework, a pivotable shaft extending between termini of said rod members remote from said base framework, a pair of elongate parallel bar members extending over said base framework and attached to said pivotable shaft and having downwardly depending shoulder pads remote from said pivotable shaft, a rod extending between said bar members between said shoulder pads and said pivotable shaft, a cylindrical rod member slideably extending downwardly therethrough and provided with means for selectively fastening said last mentioned rod together, said cylindrical rod member terminating in a weight stack having holes therethrough complemental with holes on said cylindrical rod member whereby insertion of a pin therethrough selects the magnitude of weight to be used, said weights constrained in a weight cage defined by upper and lower cross bars transverse to said cylindrical rod member which slideably extends therethrough, said cross bars interconnected at extremities thereof by a pair of cylindrical rods spaced from, shorter than, and parallel to said cylindrical rod member, said lower cross bar affixed to said base framework.
Claim 2
Dependent Claim
196 words
A standing calf machine comprising a base framework, a pair of vertically upstanding rod members extending from and supported by one end of said base framework, a pivotable shaft extending between termini of said rod members remote from said base framework, a pair of elongate parallel bar members extending over said base framework and attached to said pivotable shaft and having downwardly depending shoulder pads remote from said pivotable shaft, a rod extending between said bar members between said shoulder pads and said pivotable shaft, a cylindrical rod member slideably extending downwardly therethrough and provided with means for selectively fastening said last mentioned rod together, said cylindrical rod member terminating in a weight stack having holes therethrough complemental with holes on said cylindrical rod member whereby insertion of a pin therethrough selects the magnitude of weight to be used, said weights constrained in a weight cage defined by upper and lower cross bars transverse to said cylindrical rod member which slideably extends therethrough, said cross bars interconnected at extremities thereof by a pair of cylindrical rods spaced from, shorter than, and parallel to said cylindrical rod member, said lower cross bar affixed to said base framework.
Claim 3
Dependent Claim
48 words
The device of claim 1 wherein said means for selective fastening comprise an apertured sleeve, holes in a top portion of said cylindrical rod member which passes through said apertured sleeve which overlies said rod(21) whereby a pin extending therethrough can alter the height of said shoulder pads.
Claim 4
Dependent Claim
23 words
The device of claim 2 including handle members disposed on outer faces of said elongate parallel bar members to assist in height adjustment.
Claim 5
Dependent Claim
27 words
The device of claim 3 including a toe pad on said base framework remote from said vertically upstanding rod members to give purchase for the calf exercise.
Claim 6
Dependent Claim
19 words
The device of claim 4 including diagonal braces extending from said base framework to said vertically upstanding rod members.
