Abstract
Abstract A ski exercise machine is provided. The machine includes side-by-side, wheeled foot skate assemblies positioned on three tracks, a center track and two outer tracks. Movable arm poles are operably connected to the center track and extend generally upwardly and outwardly from between the skate assemblies. The foot skates are attached to an adjustable resistance belt system and the arm poles are rotated about an adjustable resistance system. The ski exercise machine is ergonomically designed for aesthetic appearance as well as function and utility in exercising.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
162 words
An exercise machine for providing exercise for a user by simulating cross-country skiing, said machine comprising: two generally parallel, spaced outer tracks; a center track having a longitudinal axis, said center track disposed generally between and parallel to said outer tracks; a pair of reciprocating skate means for receiving said user's feet, said pair of skate means each operably coupled to said center track and a respective outer track; right and left arm pole means for said user to grasp and move, each of said arm pole means pivotally coupled to said center track, each extending from said center track in respective vertical planes parallel to said longitudinal axis of said center track, each diverging from said center track, and each terminating in respective vertical planes in the vicinity of said outer tracks, whereby said arm pole means do not interfere with said user's body while exercising; and skate resistance means for adjustably varying the resistance of said skate means to movement.
Claim 2
Dependent Claim
162 words
An exercise machine for providing exercise for a user by simulating cross-country skiing, said machine comprising: two generally parallel, spaced outer tracks; a center track having a longitudinal axis, said center track disposed generally between and parallel to said outer tracks; a pair of reciprocating skate means for receiving said user's feet, said pair of skate means each operably coupled to said center track and a respective outer track; right and left arm pole means for said user to grasp and move, each of said arm pole means pivotally coupled to said center track, each extending from said center track in respective vertical planes parallel to said longitudinal axis of said center track, each diverging from said center track, and each terminating in respective vertical planes in the vicinity of said outer tracks, whereby said arm pole means do not interfere with said user's body while exercising; and skate resistance means for adjustably varying the resistance of said skate means to movement.
Claim 3
Dependent Claim
72 words
The exercise machine according to claim 1, wherein said skate means includes a first foot-receiving skate means for reciprocating movement generally parallel to and between said center track and one of said outer tracks, and a second foot-receiving skate means for reciprocating movement generally parallel to and between said center track and the other of said outer tracks, said first and second foot skate means being operably coupled to said respective tracks.
Claim 4
Dependent Claim
57 words
The exercise machine according to claim 1, and arm pole resistance means for adjustably resisting the movement of said right and left arm pole means, said arm pole resistance means operably coupled to said right and left arm pole means and to said center track, said skate resistance means being independent of said arm pole resistance means.
Claim 5
Dependent Claim
76 words
The exercise machine according to claim 1, wherein said skate resistance means comprises: a belt; front hub means for receiving said belt, said front hub means operably coupled to and substantially covered by said center track; rear hub means for receiving said belt, said rear hub means operably coupled to and substantially covered by said center track; and adjustment means for adjusting the tension of said belt, said adjustment means operably coupled to said front hub.
Claim 6
Dependent Claim
78 words
The exercise machine according to claim 4, wherein said front and rear hubs are mounted substantially completely under said center track, and wherein said belt has opposing runs under said center track and extends around said hubs in taut relation, each one of said opposing runs of said belt being connected to a different one of said skate means, said adjustment means connected to said center track and engaging at least one of said runs of said belt.
Claim 7
Dependent Claim
48 words
The exercise machine according to claim 3, wherein said arm pole resistance means comprises torque means connected to said arm pole means for resisting the movement of said arm pole means, said torque means being coupled to said center track adjacent the longitudinal axis of said center track.
