Abstract
Abstract A stationary exercising device which promotes cardiovascular exercise yet minimizes impact to critical joints, particularly the ankles and knees. A frame supports a linkage assembly having at least one linkage member with a camming surface. The linkage assembly is in turn connected to a coupling system attached to the frame. Structure is included which permits each foot of the user to move the linkage assembly in such a manner as to generate a preferred closed path movement for the foot in a preferred anatomical pattern minimizing unnecessary stress in the joints yet permitting a cardiovascular workout.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
315 words
An exercise device comprising: a frame having a base portion adapted to be supported by a floor; camming means supported by said frame; a first linkage assembly having a first reciprocating member and a first foot member, said first reciprocating member having a first end and a second end, said first end of said first reciprocating member being adapted for linear movement substantially parallel with the floor, said first foot member having a first and second end, said first foot member being pivotally attached proximate said first end of said first foot member between said first and second ends of said first reciprocating member proximate said first end of said first reciprocating member, said second end of said first foot member adapted to engage and move along said camming means; a second linkage assembly having a second reciprocating member and a second foot member, said second reciprocating member having a first end and a second end, said first end of said second reciprocating member being adapted for linear movement substantially parallel with the floor, said second foot member having a first and second end, said second foot member being pivotally attached proximate said first end of said second foot member between said first and second ends of said reciprocating member proximate said first end of said second reciprocating member, said second end of said second foot member being adapted to engage and move along said camming means; and a coupling member having a pulley supported by said frame defining a pivot axis and means for attaching said second ends of said first and second reciprocating members to said pulley so that rotation of said pulley results in the rotation of the second ends of said reciprocating members in a substantially circular path about said axis and wherein each foot of the user of the device follows a predetermined closed path having a preferred anatomical pattern.
Claim 2
Dependent Claim
315 words
An exercise device comprising: a frame having a base portion adapted to be supported by a floor; camming means supported by said frame; a first linkage assembly having a first reciprocating member and a first foot member, said first reciprocating member having a first end and a second end, said first end of said first reciprocating member being adapted for linear movement substantially parallel with the floor, said first foot member having a first and second end, said first foot member being pivotally attached proximate said first end of said first foot member between said first and second ends of said first reciprocating member proximate said first end of said first reciprocating member, said second end of said first foot member adapted to engage and move along said camming means; a second linkage assembly having a second reciprocating member and a second foot member, said second reciprocating member having a first end and a second end, said first end of said second reciprocating member being adapted for linear movement substantially parallel with the floor, said second foot member having a first and second end, said second foot member being pivotally attached proximate said first end of said second foot member between said first and second ends of said reciprocating member proximate said first end of said second reciprocating member, said second end of said second foot member being adapted to engage and move along said camming means; and a coupling member having a pulley supported by said frame defining a pivot axis and means for attaching said second ends of said first and second reciprocating members to said pulley so that rotation of said pulley results in the rotation of the second ends of said reciprocating members in a substantially circular path about said axis and wherein each foot of the user of the device follows a predetermined closed path having a preferred anatomical pattern.
Claim 3
Dependent Claim
15 words
The exercise device according to claim 1 wherein said camming means comprises a curved profile.
Claim 4
Dependent Claim
71 words
The exercise device according to claim 1 wherein said coupler member attaching means comprises: a first element attached at one end to said pulley proximate said pivot axis and at its other end to said second end of said first reciprocating member; and a second element attached at one end to said pulley proximate said pivot axis and at its other end to said second end of said second reciprocating member.
Claim 5
Dependent Claim
61 words
The exercise device according to claim 3 wherein said first element comprises means to adjust the length of said first element between said pivot axis and said second end of said first reciprocating member, and said second element comprises means to adjust the length of said second element between said pivot axis of said second end of said second reciprocating member.
Claim 6
Dependent Claim
26 words
The exercise device according to claim 1 wherein said frame further comprises a top portion adapted to provide hand support for the user of the device.
Claim 7
Dependent Claim
25 words
The exercise device according to claim 2 wherein said sloped camming means comprises a pair of members having substantially identical curvatures attached to said frame.
Claim 8
Dependent Claim
51 words
The exercise device according to claim 1 wherein said first reciprocating member includes means to adjust the length between said first and second ends of said first reciprocating member, and said second reciprocating member includes means to adjust the length between said first and second ends of said second reciprocating member.
Claim 9
Dependent Claim
30 words
The exercise device according to claim 1 wherein said device further comprises means for introducing a resistive force to said pulley so rotation of said pulley becomes progressively more difficult.
