Abstract
Abstract A resistance exercising machine having a similarly configured triangularly shaped main frame adapted to carry at least one stack of weights and a pivoted engagement mechanism which is operably coupled with the weights and is adapted to be engaged by the trainee to cause a controlled movement of the mechanism relative to the main frame against the urging of the weights.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
193 words
An exercising apparatus, comprising: (a) a triangularly shaped main frame including a base member adapted to engage a supporting surface, a generally vertically extending guide means connected to said base member and an angularly extending member interconnecting said base member and said guide means; said base member and said angularly extending member being disposed in a coplanar relationship; (b) body engaging means carried by said main frame for movement with respect thereto for engagement by the user during the performance of exercises, said body engaging means comprising a pair of spaced apart lever arms disposed on opposite sides of the plane of said base member and said angularly extending member, said lever arms being pivotally connected to said angularly extending member and having proximate one end thereof engagement means for engagement by the trainee; and (c) resistance means movable relative to said guide means and operably associated with said body engaging means for yieldably resisting movement thereof in a first direction, said resistance means being operably coupled with said lever arms intermediate their ends by coupling means, whereby said resistance means will yieldably resist movement of said engagement means in a first direction.
Claim 2
Dependent Claim
193 words
An exercising apparatus, comprising: (a) a triangularly shaped main frame including a base member adapted to engage a supporting surface, a generally vertically extending guide means connected to said base member and an angularly extending member interconnecting said base member and said guide means; said base member and said angularly extending member being disposed in a coplanar relationship; (b) body engaging means carried by said main frame for movement with respect thereto for engagement by the user during the performance of exercises, said body engaging means comprising a pair of spaced apart lever arms disposed on opposite sides of the plane of said base member and said angularly extending member, said lever arms being pivotally connected to said angularly extending member and having proximate one end thereof engagement means for engagement by the trainee; and (c) resistance means movable relative to said guide means and operably associated with said body engaging means for yieldably resisting movement thereof in a first direction, said resistance means being operably coupled with said lever arms intermediate their ends by coupling means, whereby said resistance means will yieldably resist movement of said engagement means in a first direction.
Claim 3
Dependent Claim
93 words
An apparatus as defined in claim 1 in which said guide means includes a pair of substantially vertically disposed guide elements located on either side of the plane of said base member and said angularly extending member and in which said coupling means comprises a pair of first sleeve means interconnected with said resistance means and adapted for reciprocal movement relative to said guide elements of said guide means and a pair of second sleeve means interconnected with said first sleeve means for receiving therethrough said lever arms of said body engaging means.
Claim 4
Dependent Claim
38 words
An apparatus as defined in claim 2 in which each of said second sleeve means carries a fixedly mounted fulcrum means for engagement with said lever arms as said lever arms are moved in an upward first direction.
