Definitions

  • longitudinal movement of the skis may be imparted by a crank arrangement which acts upon flexible pulley cords or belts to lengthwise shift the skis.
  • a further embodiment of the invention contemplates vertical pivotal movement of each roller through the provision of a hydraulic cylinder drive arrangement which is operatively associated with lever members acting upon the rollers.
  • a further embodiment of the invention and serving for producing irregular longitudinal and transverse tilting movement of the skis contemplates eccentrically mounting the rollers upon transverse axles, the forward and rearward rollers of each pair being counter rotated by means of a gear train, the rollers supporting one ski rotating faster than those supporting the other ski to thereby produce both longitudinal and tilting movement of the skis.
  • the invention also teaches the possibility of not powering the rollers but having such mounted so as to be freely rotatable in response to forward and rearward movement of the skis.
  • Weights or springs may be used for rotationally biasing the rollers to a rest position and providing resistance against rotation.
  • Hydraluc cylinders or cam operated crank arms may also be prov1ded for effectmg vertical or pivotal movement of each roller relative to the others.
  • This invention relates to ski training devices, and particularly to a practice device for simulating the movements involved in actual skiing.
  • One such known device comprises a plurality of mats having bristles or the like ontheir upper surfaces, which mats may be placed semi-permanently upon a level surface or a slope and which offer a fair substitute for snow for skiing upon.
  • mats must cover a wide area and hence take up a great deal of space, and inasmuch as they represent a considerable investment of space and money, these mats can obviously not be used in all cations and under all circumstances where they might otherwise be desirable.
  • a ski training device which, generally speaking, comprises at least one supporting means movable elevationally and in the lengthwise direction of the ski, and upon which the ski always bears.
  • the invention comprises supporting means for each ski comprising at least a pair of rollers having parallel axes disposed transversely to the axes of the skis, the skis resting either directly upon the rollers or upon endless belts passing around and extending between the forward and rearward rollers in each pair.
  • the rollers are eccentrically mounted upon their transverse axles out of phase with respect to each other and the rollers of each pair are counter-rotated by a motor and gear drive so that alternate forward and rearward longitudinal and tilting movements are produced.
  • Means are provided for sequential or independent vertical and pivoting movements of the respective axles to further produce sideways tilting motions.
  • the rollers are non-powered and rotate responsive to longitudinal movements of the skis thereupon.
  • the rollers are centrally mounted upon their respective axles and include means to bias each roller rotationally to a rest position and/or means to produce vertical or pivotal movements of each axle.

  • Flooring panels 7, 8, and 9 fill the spaces in front of forward rollers 2 and 3 and behind the rearward rollers l and 4 as well as between the forward and rearward rollers, and are recessed below the upper surfaces of the rollers.
  • Control rod 10 is connected by a suitable mechanical linkage, switch means, or other means, not shown, to control means within a vertically extending control housing 14 situated at one corner of the device, and serves to control the on-off operation of the device.
  • control rod 10 may be rigidly secured to vertical support member 11 at one end thereof, which support member is pivotable about its lower end within side wall 6, and is suitably connected to a linkage or switch means so that lateral displacement of control rod 10 to either side of its central vertical position, in the direction of the double arrow, will actuate the drive means for the rollers.
  • control rod 10 release of control rod 10 to its central upright position, for instance, will shutrdown the device and thus acts as a so-called dead-man control.
  • floor panels 7, 8 and 9, or any combination thereof, if desired, can also function to shut-off the mechanism, as in the event the skier falls from the rollers onto one of the panels. Then the floor panels act also as dead-man pedals with a reverse switching action.

  • Drums 1 and 2 corresponding generally to drums 1 and 2 in FIGS. 1 and 2, are rotatably mounted on the inner ends of horizontal portions of lever arms SH-l and SH-Z, respectively, and are counter-rotated by means of drive motors M-l, M-2 and drive belts R-l and R-2, respectively, the drive motors also being secured to the respective lever arms to pivot therewith.
  • Lever arms SH-1 and SH-2 pivot about fixed pivot points secured to the frame, and have the lower ends of their vertical portions pivotally connected to the outer ends of piston rods PL-l and PL-2, which piston rods have pistons Pk-l and PK2 on the opposite ends thereof, sliding within hydraulic cylinders P-1 and P-2, respectively.
  • the hydraulic cylinders P-1 and P-2 may be kept at a constant pressure or may be subject to a cyclically variable pressure to effect oscillating motion of the lever arms SH-l and SH-2 and hence the drums I and 2.
  • the center of gravity shifts accordingly and exerts greater or lesser pressure on each of the respective drums l and 2, thus creating a greater or lesser frictional force between the rotating drum and the SK and resulting in the ski being driven alternately forwardly and backwardly as the weight shifts.
  • the skier is constantly forced to shift his own weight to compensate for or match these movements of the skis.
  • FIG. 4 Means are shown in FIG. 4 for producing irregular longitudinal and transverse tilting of the skis.

  • the toothed gears on each side of the device are driven by a motor M-ll, M-Z through bevel gear pair W-l, W-2 and a pair of counter-rotating gears ZS, Z6 and Z-7, 2-8, which respectively engage the gears 2-1, 2-2, 2-4, and 2-3.
  • Gears 2-5 and Z7 of each counter-rotating pair each have fewer teeth than gears Z6 and 2-8 of the respective pairs, so that forward drums 2" and 3 rotate at a greater speed that rear drums 1" and 4".
  • motors M-ll and M-12 may operate at different speeds so that all four drums are rotating at different speeds from each other. Due to the eccentric mounting of the rollers upon their respective hollow shafts, rotation of the rollers will produce a highly irregular cyclic pattern of longitudinal and transverse tilting of the skis SK supported thereby, particularly if different drive speeds are used for the rollers. Alternately, the forward and rearward rollers may be driven at the same speed, in which case the rollers are constantly out of phase and produce a regular tilting movement whose frequency will depend upon the rotational speed of the rollers.
  • FIGS. 5 through 9 depict modifications of the invention which can be utilized to effect various combinations of tilting motions.

  • the weight of rollers 100, 200 will keep the cam followers 111, 112 biased towards the surface of cam EX. and that rotation of the cam will cause the lobes to move the cam follower rollers I11, 112 outwardly and hence pivot the supports for rollers 100 and 200 upwardly.
  • any desired pattern or sequence of pivoting may be provided for rollers
  • rollers 100 and 200 and endless belt 101 are not power driven but are substantially free to rotate responsive to forward and rearward longitudinal movements of the skier, depicted by arrow SKB.
