Abstract:
1. A ski-exercising and rehabilitation apparatus comprising: a. a drive motor; b. a frame having a rectilinear base having two sides and a forward end and a rearward end and two side members each attached to the base at first and second attachment points proximate to the forward and rearward ends of the base respectively, the side members each defining a convex arcuate upper profile from the first end to an apex; c. an upper drive roller connected to each side member about a first axis joining the apex of each side member and adapted to be driven rotatably thereabout by the drive motor; d. a lower drive roller connected to each side member about a second axis joining each side member along a point equidistant along the upper profile and proximate to the first attachment point and adapted to be driven rotatably thereabout by the drive motor in the same direction as the upper drive roller; e. a plurality of freely rotatable rollers extending between corresponding points of the upper profile of each side member between the upper and lower drive members; f. an endless material loop surrounding the upper and lower drive rollers and the freely rotatable rollers; g. a covering extending between corresponding portions of the upper profile of each side member beyond the endless material loop; and h. a pair of support sticks extending substantially uprightly from the cover, each support stick having a handle positioned over the endless material loop; wherein the upper profile has a maximum perpendicular extension beyond a line connecting the apex and the first attachment point of between 2 and 5 cm.
