Definitions

  • the invention relates to a wheeled ski, simulating a snow ski, comprising a frame supported by a front wheel axle and a rear wheel axle, in which a rolling movement caused by the user on the frame causes a change of direction of a train of wheels.
  • the snow ski simulation device allows beginners of all ages to adapt safely to cross-country and downhill skiing.
  • skates and skates currently used are in no way comparable in their behavior with various existing snow skis.
  • wheeled skis corresponding to the preamble of claim 1 (Document US-A-3,545,779) designed to carry out a series of turns during a descent.
  • a lateral tilting movement of the central part pivoting along a longitudinal axis causes a change of orientation of the front axle and the rear axle of the wheels which triggers the turn.
  • a safety binding keeps the shoe flat without the possibility of lifting the heel.
  • the wheels are not protected and to avoid contact between the two skis, the movements must be strictly symmetrical in order to constantly keep the skis parallel and slightly apart. This practice requires great precision, which is difficult to obtain with beginners who are often inconsistent.
  • the blocking of the heel decreases the amplitude of the movement in displacement in alternating steps.
  • the wheeled ski according to the invention is characterized in that the eccentric front axle, of integral wheels is fixedly attached to the frame without the possibility of changing direction, while the rear wheel axle is articulated by a vertical axis on this frame and in that the frame, in its central part, comprises a set of two pedals, one of brake, the other of direction, the latter supporting the foot of the user and being itself supported with possibility lateral pivoting by the brake pedal, which is itself mounted on a horizontal and transverse axis secured to the frame, these pedals acting according to their respective function on the rear axle of the wheels by means of appropriate mechanisms.
  • the invention as characterized in the claims solves the problem of creating a device allowing the adaptation of beginners of all ages to the practice of cross-country skiing and alpine skiing.
  • the result is a complete, attractive physical preparation, with beneficial repercussions in terms of accident prevention, greater motivation to orientate oneself towards this sporting activity, and easier to follow the lessons of the ski school. It can be practiced indoors, on sports grounds, with the use of an elevated runway or on an equipped track equipped with a ski lift.
  • the eccentric front axle significantly increases the surface of the lift polygon, making it possible to combat centrifugal force during the turn and great stability during use in mono.
  • the eccentric front axle, of integral wheels ensures a progressive deceleration during each turn as a result of a slight skidding of the wheels, due to the difference in length of the radius of the interior and exterior curve. Therefore, it is possible to control the speed as it occurs during the skidding of skis on snow when driving turns.
  • micrometric adjustment of the rectilinear trajectory of each ski is carried out very easily by barrels, without taking off the skis.
  • the safety brake the activation of which requires the balanced recoil position beforehand, makes it possible, if necessary, to stop the chain of turns and to continue the movement in direct track by occupying only one side of the track.
  • the wheeled ski according to the invention allows beginners and particularly the blind to evolve on a varied terrain in order to adapt to the practice of cross-country and alpine skiing. It can be used for hiking or with the help of ski lifts.
  • It essentially comprises a frame (C) and a double control pedal comprising a brake pedal element (F) and a steering pedal element (D) supported by said element (F).
  • the frame (C) can be made of metal, fiberglass or any other light, flexible, resistant material. It comprises vertical side parts (6) covered with a smooth material reducing friction and protecting the wheels (7. 7A) which, thus, cannot catch on during the movement in alternating steps.
  • the outer rear part of the frame is notched so as not to hinder the pivoting of the wheels outside (fig.3).
  • the wheels can advantageously be fitted with tires of all types.
  • the skier's center of gravity is lowered by fixing the shoes between the wheels, and as close as possible to the ground.
  • wheeled skiing is relatively long, but the size should be compared to that of snow skis and not that of skates or skates whose use is completely different.
  • the rear axle (4) comprises two integral wheels (7A), bolted to a ball bearing hub (10) or any other system on which a brake disc (11) is fixed, the assembly being supported by a pivoting fork (12) itself mounted on the rear of the frame with, if necessary, assistance means (not shown).
  • the eccentric front axle (2) comprises two integral wheels (7) bolted to a hub (10) on which are fixed two toothed wheels (13) on which two pawls (14) act. Any other freewheel system preventing the ski from rolling back can be used.
  • a brake is arranged between the rear wheels, to act either directly on the central part of the hub, or on the vertical disc (11) provided for this purpose.
  • the wheels being integral, braking takes place simultaneously on the two rear wheels.
  • the lifting of the brake pedal element causes the movement of a right angle bent lever (18 - 19), the part (19) of which carries a cam (20).
  • This cam is intended, on the one hand, to push a piece in the shape of a "U” (21) which, by means of axes (22), brings the jaw (16) closer to the disc, and, on the other hand hand, by resting on the part (21), pushing the jaw (16A) also towards the disc.
  • Two return springs (23) return the jaws (16 - 16A) to their initial position by sliding guides (24) on an axis (25) the ends of which are held by an inner nut (26) and an outer nut (27 ).
  • the brake pedal element (F) which supports the steering pedal element (D) pivots about an axis (28) located slightly in front of the vertical passing through the heel. The position of this axis is adjustable according to the size of the skier.
  • the brake pedal element (F) - steering pedal element (D) assembly lifts at the front; the part located behind the axis of rotation (28) descends, pulling on a flexible transmission (29) fixed at (30) on the element (F), which transmission acts on the brake lever (18 -19) .
  • This last lever, in contact with the cam (20) causes the jaws (16 16A) to come together which slow down the rotation of the disc (11) located between the rear wheels (7A).
  • the rear part of the pedal approaches the ground. It includes a large rubber pad (31) or other similar material which can, in the event of a break in the flexible transmission, press the ground directly and thereby act as an emergency brake.
  • the brake can be removed and replaced by direct braking on the ground.
  • the support on one side of the skate causes the change of direction.
  • the user must seek the elevation on one side of the pedal by moving the two knees together on the opposite side. This roll movement is identical to that performed on snow for a series of turns.
  • An axis (34) on which a double transmission (34A-34B) is fixed moves to the right in this case, causing the operation of the elements of the transmission which act on the pivoting fork (12) and cause its rotation.
  • the flexible double transmission (34A - 34B) includes adjusting barrels (36) which can be used without taking off the shoes in order to obtain a perfectly rectilinear movement (Fig. 13).
  • the pivoting mechanism of the fork is locked when the ski is back, body weight on the front ski.
  • the center of gravity is during this phase on the front part of the binding of the rear ski, the heel being raised: the rear part of the steering pedal lifts, a cam (35) engages in the cylindrical guides (37) and blocks the entire steering mechanism, the ski moves in a straight line.
  • the cam (35) is released and can pass below the guides (37) to perform the movements lateral allowing turns.
  • the body weight is distributed over the entire surface of the foot.
  • the steering pedal presses flat on its guides (32) which pass through the brake pedal element (F) through holes (39) to allow rotation of the steering pedal element (D) on the tubes ( 33).
  • an upper pulley (46) mounted by a pin (47) on the upright (45) leaves the center and tends to move laterally under the action of the elastic element (40) the tension of which is adjustable at its fixing point (41), improving the operation of the steering.
  • a window (48) is formed in the flange (42) to allow the movement of the axis (47) through this flange and the upper pulley (46) is likely to meet on the flange (42) an inclined plane ( 49) in two parts leaving between them a central part.
  • a window arrangement (48A) is also adopted to allow the movement of the transmission axis (34) through a flange (42A) disposed opposite the flange (42) on the '' brake pedal element (F).
  • an arrangement with a lower pulley (43A) mounted on an upright (45A) of the steering pedal element (D) and associated with an elastic or spring (40A) fixed at (41A) on a flange (42A) of the brake pedal element (F) is provided at this end of the steering pedal element (D) and brake pedal element (F) assembly.
  • the steering pedal element (D) is suspended in a cradle on the brake pedal element (F).
  • a device (50) keeps the brake pedal element (F) in a horizontal position.
  • This mechanism is fixed by two bolts (51) on the part (2) of the frame. It receives and blocks an axis (52) fixed on the flange (42) of the brake pedal element (F) when the skier is in the descent position.
  • This lever mechanism (53) for locking a pivot axis (54) is adjustable by tensioning a spring (55) connecting the levers, according to the weight of the ski.
  • the axis (52) lifts, draws aside the levers (53) which blocked it, and the brake pedal element (F) is released.
  • the shoe must transmit all movements to the braking and steering mechanism. This movement is lateral or anteroposterior.
  • the flat foot In the descent position, the flat foot is locked at the heel by a guide (57) preventing any lateral movement.
  • Poles of snow skis whose point is provided with a rubberized or metallic tip, depending on the state of the ground, can be used normally.
  • the wheeled ski according to the invention simulating snow skis, makes it possible to move in a straight line, go up, down, brake, turn using the movements of the lower joints of the individual, as happens on snow.
  • the wheeled ski according to the invention offers great security.
  • the brake pedal lifts and the brake comes into action; the skier moves forward while the ski is blocked. As a result, the balance is restored and the fall back is avoided.
