Ski exercising and rehabilitation apparatus
First Claim
1. A ski-exercising and rehabilitation apparatus comprising:
- (a) frame having a substantially rectilinear base having two sides, a forward end and a rearward end, and two side members 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 forward and rearward ends to an apex;
(b) a downhill-run unit supported by the frame and comprising;
(i) a first and a second external clamping beam substantially longitudinally parallel and each having first and second ends;
(ii) an upper drive roll connected to the first and second external clamping beams at their respective first ends;
(iii) a lower drive roll connected to the first and second external clamping beams at their second ends;
(iv) a central beam located between and substantially parallel to the first and second external clamping beams, the central beam having a first central beam end and a second central beam end, the central beam ends being supportably connected to respective first and second shock absorbers;
(v) a plurality of rotatable rolls each mounted in bearings in the central beam and one of the first and second external clamping beams;
(vi) a drive means comprising at least one motor;
(vii) rocking means operatively connecting each of the external clamping beams to the drive means;
(viii) actuator means operatively connecting each of the external clamping beams to the frame; and
(ix) a track mat having a bristled upper surface and being supported by the upper and lower drive rolls and at least some of the rotatable rolls, and having light sign means provided to the bristled upper surface.

Abstract
A ski-exercising and rehabilitation apparatus of the invention wherein the down-hill-run unit (22), has a system of rotatable rolls (25) mounted with bearings in external clamping beams (20) and (21) and in the central beam (26) so that their rotation axes lie in one arched plane, whereas said central beam (26) is supported on its ends with shock absorbers (27), whereas the ends of external clamping beams (20 and 21) are jointed at one end with the shorter articulated connecting rods (18 and 19) of variable lengths and at the other end with the longer articulated connecting rods (23 and 24) of variable lengths, the other ends of which are rotatably connected with respective discs of the gear wheels (13, 14, 15 and 16) mounted on the front drive shaft (11) and rear drive shaft (12), said external clamping beams (20 and 21) being also jointed to rocking levers (34 and 35) which are connected to actuators (36) mounted in the frame base (1) of the apparatus, whereas the light signs (54), imitating the positions of slalom poles, are located on the track mat (30) of said downhill-run unit (22) in form of bristled track mat banding arcwise the upper drive roll (32) and lower drive roll (31).
