Definitions

  • the present invention relates to a board for sliding on snow, this board can be made up of skiing, surfing, a monoski, the ski considered being able to be of alpine ski, nordic ski type or cross-country skiing.
  • This gliding board is of the type comprising a set lower composed of a sole possibly bordered by edges metallic and possibly associated with a lower reinforcing layer, a central core possibly associated with reinforcing elements, and an upper shell forming a shell, composed of a wall upper extended laterally by side walls whose edges lower are supported on two longitudinal reinforcing elements themselves resting on the lower assembly, the upper envelope being possibly associated, on its internal face, with a reinforcing layer, this board being further equipped with at least one damping element vibrations.
  • Such a gliding board is illustrated, in the case of a ski, in document FR 2 683 734, in the name of the Applicant.
  • a gliding board When traveling on snow, a gliding board is subjected to vibrations generated by successive shocks against uneven ground on which it moves. These vibrations harm the stability of the board, its attachment to the snow, as well as its good glide, and are a source of discomfort for the user.
  • the documents FR 2 611 518 and 2 615 405 each concern a ski of the type of gliding board according to the invention, that is to say having a shell-like upper shell, the edges of which lower support on the lower assembly.
  • the ski includes a central core delimiting, with the envelope upper, lateral volumes used for housing over the entire length or almost the entire length of the ski of visco-elastic material having a damping function.
  • amortization makes the fairly inert ski due to excess damping.
  • Document FR 2 618 344 describes a cross-section ski rectangular, that is to say comprising a lower assembly, a wall upper and side edges defining a volume filled with a core. Transversal holes crossing a edge and extending over part of the width of the core are provided in the ski, these holes being filled with a damping material.
  • Document FR 2 599 636 relates to a ski comprising a core, in which recesses are provided containing elements depreciation. These damping elements can extend up to through the songs of skiing.
  • the object of the invention is to provide a board for gliding on snow, of the aforementioned type, which provides selective filtering of vibrations which are transmitted between a lower edge of the board in contact with the snow, and the upper face of the board, on which are fixed the feet of the user, depending on the type of board in question. Indeed, it is to dampen only the parasitic vibrations, because an excess vibration dampening would not result in a lack of liveliness of the ski.
  • the snowboard that it concerns includes at least one vibration damping element which is located on one side of the board and visibly opens on this side, and is located in the area between a lower edge of the envelope upper and lower assembly, this damping element constituting a direct barrier to vibrations propagating between the lower edge of the board in contact with snow and the top wall of the board on which are fixed the feet of the user.
  • the board When using a snowboard, the board fits on an internal lower edge when executing a turn.
  • a damping element is arranged between a lower edge of the upper envelope and a longitudinal reinforcing element.
  • the envelope upper comprises, at the level of a damping element, a boss upwards, delimiting a recess intended for housing at least partially of this damping element.
  • each element longitudinal reinforcement comprises, at the level of an element shock absorber, a recess facing upwards and opening into one side of the board, intended for at least partial housing of this element damper.
  • a damping element can be accommodated, to part, in a recess in the upper envelope and, for part, in a recess in a reinforcing element and opening into the upper face thereof.
  • a damping element is arranged between a lower edge of an element longitudinal reinforcement and the lower assembly, this element longitudinal reinforcement comprising a recess opening into its underside and on one side of the board, intended for housing the damping element.
  • a damping element is arranged inside an element longitudinal reinforcement, in a slit completely crossing the width of the element.
  • each damping element has a length of between 50 and 300 mm.
  • each damping element has a thickness which varies over the length thereof.
  • the thickness of each damping element is maximum in the central part of it and decreases towards its ends.
  • each damping element is locally equal to at least 2 mm, on much of the length of the element.
  • each vibration damping element is located in a belly of vibration.
  • the board according to the invention advantageously includes vibration damping elements on both sides.
  • the vibration damping elements arranged on both sides of the board can be symmetrical about the median plane longitudinal thereof, or asymmetrical with respect to the median plane longitudinal of this one, this asymmetry resulting from their positioning and / or their natures and / or their forms or respective dimensions.
  • each damping element is centered on one of the following two zones located at respective distances between 10 and 20%, and 70 and 90% of the bearing length of the board, starting from its heel.
  • a damping element centered in a area located at a distance between 75 and 80%, and preferably 77%, of the bearing length of the board, from its heel.
  • the material of the damping elements is chosen from rubber, polyurethane, EPDM (Ethylene Propylene Monomeric Diene), ABS (Acrylonitrile Butadiene Styrene) or other derivatives styrenic.
  • the ski represented in FIGS. 1, 2 and 6 comprises an assembly lower consisting of a sole 2 bordered by two metal edges 3 longitudinal, and associated with a metal reinforcing strip 4.
  • a core central 5 in synthetic foam rests on the assembly inferior.
  • This ski also has an upper casing 6 forming a shell constituted by an upper wall 7, extended laterally by side walls 8, the lower edges 9 of which are slightly turned outwards are supported on most of them, on two longitudinal reinforcing elements 10, themselves supported on the edges 3.
  • the upper envelope 6 is associated, on its inner face, with a reinforcing layer 12 constituted, for example, by an impregnated fabric resin.
  • this ski is equipped with four damping elements, arranged two by two so symmetrical with respect to the longitudinal median plane of the ski.
  • These elements shock absorbers made of visco-elastic material, have a length between 50 and 300 mm, and are each centered on one of the two following areas located at respective distances between 10 and 20%, and 70 and 90% of the carrying length of the ski from its heel.
  • each damping element 13 is disposed between a lower edge 9 of the upper envelope 6, and a longitudinal reinforcing element 10.
  • the upper envelope comprises, at the level of a damping element 13, an upward boss 14, delimiting a recess 15, intended for the housing of this damping element.
  • the element shock absorber has a height that varies over its length, this height being maximum in the central part of the element and decreasing towards its ends.
  • the thickness of each damping element is at least 2mm across most of its length.
  • the damping element 13 is always disposed between a lower edge 9 of the upper envelope 6, and a reinforcing element 10.
  • the reinforcing element has a recess 16 open at the top, and opening into one side of the board, intended for housing the damping element.
  • the damping element is arranged between a lower edge of an element longitudinal reinforcement 10, and a metal edge 3 of the ski.
  • the longitudinal element reinforcement 10 has a recess 17 open at the bottom and opening laterally into one side of the board.
  • a damping element 13 is arranged inside a longitudinal element reinforcement 10, while opening into one side of the board.
  • the damping element is housed in a slot 18 formed in the longitudinal element 10, over the entire width thereof.
  • FIG 10 shows, in exploded view, an embodiment identical to that shown in Figures 3 and 7, but in which the metal reinforcement 4 is replaced by a fabric 19 impregnated with resin forming a lower reinforcement, which rests on the upper face of the sole 2 and the edges 3.
  • the invention is not limited only to embodiments of this gliding board, described above as example in the context of alpine skiing, on the contrary it embraces all execution variants.
  • This is how the number and the position of the damping elements could be different, than these could be arranged asymmetrically on both sides of the ski, that the shape or dimensions of the shock absorbers could vary or that the damping element could be housed in the thickness of a longitudinal reinforcing element consisting of two superimposed parts with two opposite recesses for delimit a housing for this damping element.
