Ski exercise machine

Claim 2

A ski exercise machine according to Claim 1, characterised in that it comprises: two substantially parallel tracks (12, 14 and 12, 16); two foot skates (22, 24) mounted respectively on said tracks by means of wheels (86, 88, 90, 92); a belt or web (109) secured to and linking the foot skates; and adjustable tensioning means (109, 176, 178, 180, 194) to tension the belt or web and thereby pre-determine the resistance to longitudinal movement of the foot skates in their respective tracks.

Claim 3

A ski exercise machine characterised in that it comprises: a. opposing side tracks (14, 16) at a first elevation; b. a center track (12) between said opposing side tracks at a second elevation; c. cross bars (18, 20) securing said tracks with respect to each other; d. two foot skates (22, 24) in said tracks and including opposing wheels (86, 88, 90, 92) and skate anchors (104) for anchoring a web (109) secured to each foot skate; e. a rear hub under said center track; f. a front hub; and g. an adjustable tensioning means (109, 176, 178, 180, 194) to tension said web.

Claim 4

A ski exercise machine according to Claim 3, which includes opposing movable arm pole means (30, 32) secured to a front of said center track for movement by a user.

Claim 5

A ski exercise machine according to Claim 4, which includes an electronic mounting housing.

Claim 6

A ski exercise machine characterised in that it comprises: a base (12, 14, 16, 18, 20); two arm poles (30, 32) mounted for pivotal movement with respect to the base thereby to simulate the movement of poles used in skiing; and the shape, dimensions and/or disposition on the base of the arm poles being such that the torque generated by movement of each of them by a user of the machine is substantially counteracted by the other arm pole.

Claim 7

A ski exercise machine according to Claim 6, which includes: two substantially parallel tracks provided by, or supported on, the base; two linked foot supports (22, 24) respectively mounted for reciprocal movement on the tracks; and means (109, 176, 178, 180, 194) to provide a predetermined resistance to said movement.

Claim 8

Resistance belt apparatus for an exercise machine, comprising: a. a front U-shaped channel (142, 144, 146) including a forwarding extending plate for anchoring under a front cross bar plate (20) and including two opposing holes (200, 204 and 202, 206) for receiving friction hubs, friction hubs (176, 178) including retaining beads (300, 302, 304, 306) for engagement in said holes, two opposing slots (186, 188) between said opposing holes, a tensioning shoe (180) with opposing tabs (182, 184) for engaging in said slots, a nut in a base of said channel, a tension bolt (124) with a knob (126) at one end; b. a rear U-shaped channel including a rearwardly extending plate for anchoring under a rear cross bar plate (18) and including opposing holes for receiving a friction hub; a friction hub (194) including a retaining bead (308, 310) for engagement in said holes; c. two skate anchors (104) secured onto and spaced with respect to each other and including a plurality of belt securing slols (110a - 110n and 228a -228n); and d. a belt (109) secured through slots (228a - 228n) in one end of said skate anchor, over said frame friction hubs (176, 178) and engages said tension shoe (180), through slots (110a - 110n) in said other bracket, about said rear friction hub (194) and secured to another end of said first bracket.
