Definitions

  • This invention relates to a device that is mounted on a ski and to a method for the practice of alpine skiing using the said device.
  • an integrated system is widely known and used in ski-building that controls the longitudinal flexibility of the skis through the action of control button with several adjustment levels installed at the tail, whose effect is to longitudinally stress up or release two integrated rods in the upper part over the entire length of the ski, by compressing or decompressing two springs fixed at their ends, previously, at the tip of the ski; this stressing up or release means that the longitudinal curvature of the ski during turning movements can be set in accordance with the wish of the skier to either make a large- radius turning movement or a small-radius movement, thus controlling the response of the ski runner to the external forces that bend it out on the horizontal axis during a turning movement.
  • Such devices have certain disadvantages, for example they only ensure the adjustment of longitudinal bending during turning movements, as described above, or they only reduce vibrations, and ensure an even bending of the ski over its longitudinal axis during a turning movement, or elevate the bindings-boots system against the snow layer etc., without reducing the effort exerted by the skier during turning movements by an additional inclination of the ski runner on its edge, which would contribute to increased safety and efficiency.
  • the device for alpine skiing to be mounted on a ski or embedded into it comprises a long rod and a short rod, fastened at their threaded external ends into some nuts that are joined together with some molded parts embedded into the ski, the said rods transmitting the force to an upper plate through hydraulic means, or in an alternative embodiment the rods transmit the force to another plate through mechanical means, in the case of hydraulic means the ends that are inside the rods being in connection with some pistons placed into two median cylinders, to the front and to the back, provided with chambers that communicate by means of a conduit, which in turn communicates by means of a short pipe, against a hole, with a distributor that has a cylindrical and translating sliding valve which directs the pressure fluid from cylinders to and from several pistons, mounted laterally to the left and to the right, placed into four cylinders mounted vertically, with two lower chambers of the first two cylinders being joined together by means of a lateral pipe, while the chambers of the other two cylinders are joined together by means of another lateral pipe,
  • Another embodiment of the device according to the invention consists in the fact that the said distributor has a casing provided with holes, against which there are two cylinders containing two pistons that are in contact with each one of two springs, and also two expansion chambers.
  • Still another embodiment of the device according to the invention consists in the fact that the front-end joint includes a molded part embedded into the ski, which encases and fastens the front median cylinder and supports a longitudinal spindle that goes through a hinge ear to the front of the plate, while the back-end joint comprises a molded part embedded into the ski that encases and fastens the back cylinder and supports a spindle that goes through a back hinge ear of the plate.
  • each of the four sensors includes two contacts, normally closed and normally open, that creates the link between a continuous power source and two solenoids that can change the position of the core along with the cylindrical sliding valve it is affixed to.
  • the device according to the invention also solves the problem through the fact that, if the plate is operated through mechanical means, the two internal end parts that have affixed on them some wedge-shaped parts at an angle of 10° - 45°, which in turn are placed into special seats, delimitated below by the upper surface of the ski and above by the lower molded wall of an upper plate, these seats being so shaped as to allow the pieces to glide in concurrence with the ski getting further out from the upper plate, guided by a front joint and by a back joint, situated laterally against an exterior edge between the upper surface of the ski and the lower molded wall of the upper plate, the front joint allowing the ski to rotate around a longitudinal axis situated at the level of the outside edge, and comprising a spindle fastened to the ski, around which the hinge ear of a part fastened to the plate can rotate, while the back joint has two degrees of freedom: one to rotate around the same longitudinal axis, and the other to glide along it, and it comprises another spindle fastened to the ski, which rotates
  • the device described above is placed under the right foot of the skier; the building of the device for the left foot mirrors the design of the former.
  • Another aspect of the invention is a method which applies by means of the device and solves the problem by partially taking over the resulting forces applied to the tip and tail areas of the ski, in relation to the central part of the ski, which produce a longitudinal bending during a turning movement by the skier, and using the force that results from this to effect a mechanical work that results in an interactive positioning of the sliding plane of the ski in relation to the skier's sole plane, and returning to the initial position as soon as the ski is no longer bent.
  • the method according to the invention consists also in the fact that the interactive positioning of the ski in relation to the skier's sole plane is being achieved by hydraulic means and by the resulting force and, depending on the sense of the turning movement, there is a simultaneous positioning of both skis in relation to the skier's sole plane, increasing the inclination angle between the snow layer plane and the skier's sole surface, the value of this additional angle being mainly determined by the elasticity of the ski, its shape, the weight of the skier, the radius of the turn and the speed of turning.
  • the method according to the invention provides the fact that the interactive position is achieved through mechanical means by the resulting force, a situation where the skier's sole that finds itself on the outside of the turn is inclined against the snow surface at a larger angle than the usually known inclination of the ski, through the mechanical movement of a plate that is in contact with the ski boot sole, so that it creates an additional force that transmits to the ski at the level of its edge.
  • the method according to the invention refers also to the fact that the skis achieve a rotation movement around a longitudinal axis, the amount of angular movement depending mainly on the amount of the longitudinal bending of each ski during a turning movement, simultaneously with the achievement of a relative movement along a longitudinal axis against the skier's sole planes and the upper plates of the devices.
  • the method according to the invention refers also to the fact that, during a turn made by the skier, the resulting forces applied to the tail and tip areas of the ski are partially taken over, in order to effect a mechanical work whose result is to move along the gliding plane of the ski against the skier's sole plane.

  • Each one of sensors 30, 31 , 32 and 33 includes two contacts, r and s, normally closed and normally open, which make the link between source 43 and solenoids 35 and 36.

Abstract

La présente invention concerne un dispositif qui est monté sur un ski et un procédé pour la pratique du ski alpin à l’aide dudit dispositif. Le dispositif selon l’invention, monté sur un ski ou inclus dans celui-ci, comprend une longue tige (1 ou 60) et une tige courte (2 ou 61), fixées à hauteur de leurs extrémités externes filetées (e, f, a', b') dans certains écrous (8, 9, 62, 63) qui sont joints ensemble avec certaines pièces moulées (11, 12, 64, 65) incluses dans le ski (10), les tiges (1 et 2) transmettant la force à une plaque supérieure (29) par l’intermédiaire de moyens hydrauliques pendant que les tiges (60 et 61) transmettent la force à une autre plaque (68) par l’intermédiaire de moyens mécaniques. Le procédé selon l’invention est caractérisé en ce que, lors d’un mouvement de virage réalisé par le skieur, il se produit une transmission partielle des forces résultantes appliquées aux zones de pointe et de queue du ski, par rapport à la partie centrale du ski, ce qui produit une courbure longitudinale lors d’un mouvement de virage par le skieur, et l’utilisation de la force qui résulte de cela pour effectuer un travail mécanique qui entraîne un positionnement interactif du plan de glisse du ski en relation avec le plan de la semelle du skieur, et le retour à la position initiale dès que le ski n’est plus courbé.
