Description

La présente invention concerne un ski, ou autre planche de glisse sur neige, comportant des chants latéraux rigides et distincts, matérialisés par des éléments de renfort rigides en forme de baguettes longitudinales.The present invention relates to a ski, or other gliding board on snow, with rigid and distinct side edges, materialized by stiff reinforcement elements in the form of longitudinal rods.

La présente invention concerne également un procédé de réalisation de chants latéraux rigides et distincts sous la forme d'éléments de renfort rigides.The present invention also relates to a method for producing rigid and distinct lateral edges in the form of rigid reinforcement elements.

Domaine de l'inventionField of the invention

La Figure 1 représente, schématiquement et en coupe transversale, un ski traditionnel.Figure 1 represents, schematically and in cross section, a traditional skiing.

Ce ski présente :

  • un ensemble inférieur comprenant une semelle de glissement 1 bordée de part et d'autre par des carres métalliques latérales 3 et 4 ; cet ensemble est surmonté d'une couche de renfort fibreux 2 ;
  • un noyau 5 surmontant cet ensemble inférieur, et bordé de part et d'autre par deux éléments de renfort en longerons rigides 6, 7 ; et
  • un ensemble supérieur comprenant une couche de renfort fibreux 15, surmontée d'une couche supérieure plastique 10 de protection et de décor.
This ski presents:
  • a lower assembly comprising a sliding sole 1 bordered on both sides by lateral metal edges 3 and 4; this assembly is surmounted by a fibrous reinforcement layer 2;
  • a core 5 surmounting this lower assembly, and bordered on both sides by two reinforcement elements in rigid spars 6, 7; and
  • an upper assembly comprising a fibrous reinforcing layer 15, surmounted by a plastic upper layer 10 of protection and decoration.

Les deux éléments de renfort rigides 6, 7, qui sont appelés « chants » en langage du métier, sont situés au-dessus de l'ensemble inférieur, et ils ont une épaisseur non négligeable. Les faces latérales externes 8, 9 des deux éléments de renfort rigides 6, 7 forment au moins une partie des faces latérales du ski.The two rigid reinforcement elements 6, 7, which are called "chants" in craft language, are located above the lower set, and they have a not negligible thickness. The external lateral faces 8, 9 of the two elements of rigid reinforcement 6, 7 form at least a portion of the lateral faces of the ski.

Les deux éléments latéraux de renfort rigides 6, 7 sont destinés à :

  • transmettre directement des efforts du pied de l'utilisateur à la neige ; ils permettent, en particulier, d'éviter « l'écrasement » des différents composants empilés dans la structure du ski lorsque le ski est sollicité ; la force d'impulsion générée par le skieur notamment au moment de conduite du virage, tend en effet à écraser le ski entre ses pieds et la neige ; cet écrasement se traduit par une perte de temps de réaction et une perte d'énergie donc par une perte d'efficacité ;
  • consolider la tenue des carres métalliques à l'intérieur de la structure du ski ; au cours de son utilisation, le ski est souvent malmené par la présence de pierres sur les pistes ; si l'appui situé au-dessus de la carre n'est pas assez ferme, les carres s'enfoncent ou s'arrachent sous un choc important ;
  • renforcer la structure du ski en flexion et en torsion, avec des éléments latéraux de renfort 6, 7 présentant un haut module d'Young ; on améliore les raideurs et on obtient une amélioration des résistances à la rupture ;
  • renforcer la résistance des chants du ski à l'abrasion ; les chants d'un ski alpin sont soumis à l'abrasion de la neige, à l'usure par frottement contre des obstacles rencontrés sur la piste, (sapins, rochers, ...) et à l'agression des carres de l'autre ski de la paire ;
  • participer à l'aspect esthétique du ski ; les chants du ski sont une zone bien visible de tous.
The two stiff lateral reinforcing elements 6, 7 are intended for:
  • directly transmit efforts from the user's foot to the snow; they allow, in particular, to avoid "crushing" of the various components stacked in the structure of the ski when the ski is stressed; the impulse force generated by the skier, especially at the moment of driving the turn, tends to crush the ski between his feet and the snow; this crushing results in a loss of reaction time and a loss of energy and therefore a loss of efficiency;
  • consolidate the strength of the metal edges inside the ski structure; during its use, skiing is often abused by the presence of stones on the slopes; if the support located above the edge is not firm enough, the edges sink or snap under heavy impact;
  • reinforcing the ski structure in flexion and torsion, with side reinforcing elements 6, 7 having a high Young's modulus; the stiffnesses are improved and an improvement of the breaking strengths is obtained;
  • strengthen the resistance of ski songs to abrasion; the songs of an alpine ski are subjected to the abrasion of the snow, to the friction wear against obstacles encountered on the track, (fir trees, rocks, ...) and to the aggression of the edges of the other ski of the pair;
  • participate in the aesthetic aspect of skiing; the songs of the ski are a visible zone of all.

Un ski traditionnel comporte donc des chants, ou éléments latéraux de renfort, ou longerons rigides de renfort, situés de chaque côté d'une âme centrale appelée noyau et disposés au-dessus des carres métalliques.A traditional ski therefore has songs, or lateral elements of reinforcement, or rigid reinforcing spars, located on each side of a central core called core and arranged above the metal edges.

Ces longerons peuvent avoir une longueur sensiblement égale à la longueur portante du ski, ou inférieure à celle-ci. De même, la hauteur de ces longerons peut correspondre à la hauteur totale du ski, ou être inférieure à cette hauteur.These longitudinal members may have a length substantially equal to the carrying length of the ski, or less than this. Similarly, the height of these spars may correspond to the total height of the ski, or be less than this height.

Ces longerons correspondent ainsi à un besoin de consolidation d'au moins une zone du ski soumise à des pressions ou sollicitations importantes.These spars thus correspond to a need for consolidation of least one area of the ski subject to significant pressure or stress.

Etat de la techniqueState of the art

Par exemple, il est connu par les brevets US 3.967.992, US 4.093.268, et US 4.455.037, de réaliser des skis avec des éléments de renforcement correspondant en dimensions aux surfaces latérales des skis c'est-à-dire ayant sensiblement la longueur et la hauteur du ski.For example, it is known from US Patents 3,967,992, US 4,093,268, and US 4,455,037, to make skis with reinforcing elements corresponding in size to the lateral surfaces of the skis, that is to say having substantially the length and height of the ski.

D'autres solutions intermédiaires comportant des éléments de renforcement localisés existent par les documents FR-A-2.683.734 et FR-A-2.703.915 de la Demanderesse.Other intermediate solutions with elements of localized reinforcement exist by the documents FR-A-2,683,734 and FR-A-2,703,915 of the Applicant.

Ces éléments latéraux de renfort sont de différentes natures, et différents procédés de réalisation permettent de les obtenir.These lateral reinforcing elements are of different natures, and different production methods make it possible to obtain them.

Pour la réalisation des planches de glisse comportant des carres inférieures métalliques, on trouve, à l'heure actuelle, les éléments de renfort essentiellement sous deux formes :

  • un composite lamifié, avec résine thermodurcissable à base de phénol ou de mélamine, par exemple.
  • un matériau polymère thermoplastique extrudé puis injecté tel que l'Acrylonitrile-Butadiène-Styrène (A.B.S.), par exemple.
For the realization of gliding boards with lower metal edges, there are at present reinforcing elements essentially in two forms:
  • a laminated composite with a thermosetting resin based on phenol or melamine, for example.
  • a thermoplastic polymer material extruded and then injected such as acrylonitrile-butadiene-styrene (ABS), for example.

Résumé de l'inventionSummary of the invention

L'invention a pour objet un ski, ou autre planche de glisse sur neige, dont les caractéristiques sont optimisées par l'utilisation d'éléments latéraux de renfort améliorés.The subject of the invention is a ski, or other snow-sliding board, whose characteristics are optimized by the use of lateral elements of reinforcement improved.

Un ski, ou autre planche de glisse sur neige, présentant les deux bords latéraux et longitudinaux sont constitués par des éléments en longerons rigides distincts appelés « chants ».A ski or other snow board with both edges lateral and longitudinal consist of rigid longitudinal members distinct called "songs".

Conformément à la présente invention, le ski ou autre planche de glisse sur neige est caractérisé en ce que ces chants comportent, incorporées et réparties dans leur structure, des particules métalliques inaltérables à la corrosion.According to the present invention, the ski or other board of snow is characterized in that these songs include, incorporated and distributed in their structure, metal particles uncorrelated to corrosion.

Typiquement, ces particules ou inclusions peuvent être des billes métalliques d'un diamètre maximal de 100 µm, ou des paillettes métalliques dont la longueur peut varier entre 5 et 100 µm, et elles sont arrangées de façon discrète dans la structure desdits chants. Elles sont préférentiellement en un métal noble et de densité relativement faible par rapport à l'acier. A titre de métal utilisé pour ces inclusions, on peut citer par exemple le Titane ou le Zirconium, d'aspect blanc et brillant, ou l'Or, d'aspect jaune et brillant.Typically, these particles or inclusions may be balls metal with a maximum diameter of 100 μm, or metallic flakes the length can vary between 5 and 100 μm, and they are arranged in a discreet way in the structure of said songs. They are preferably in a noble metal and relatively low density compared to steel. As a metal used for these inclusions, mention may be made, for example, of titanium or zirconium, of white appearance and brilliant, or gold, of yellow and brilliant appearance.

Conformément à un deuxième aspect de l'invention, un procédé de réalisation de chants latéraux rigides et distincts destinés à un ski ou a une autre planche de glisse sur neige comprend les étapes consistant à recouvrir une mince feuille de papier d'une couche de résine thermodurcissable, saupoudrer cette couche de résine thermodurcissable de particules métalliques, renouveler de nombreuses fois ces deux premières étapes, afin d'obtenir un empilage de feuilles encollées, mettre sous presse cet empilage et déclencher la polymérisation de la résine, et découper l'empilage aux dimensions des chants latéraux.According to a second aspect of the invention, a method of making rigid and distinct lateral edges for a ski or another snowboarding board includes the steps of covering a thin sheet of paper a layer of thermosetting resin, sprinkle this thermosetting resin layer of metal particles, renew many times these first two steps, in order to get a stack of sheets glue, press this stack and start the polymerization of the resin, and cut the stack to the dimensions of the side edges.

Conformément à un troisième aspect de l'invention, un procédé de réalisation de chants latéraux rigides et distincts pour un ski ou autre planche de glisse sur neige comprend les étapes consistant à incorporer des particules métalliques aux granulés de matériaux polymères, les extruder et découper des plaques moulées obtenues aux dimensions des chants latéraux.According to a third aspect of the invention, a method of making rigid and distinct side edges for a ski or other board snow sliding includes the steps of incorporating particles metal granules of polymeric materials, extrude and cut molded plates obtained to the dimensions of the side edges.

Description détailléedetailed description

En se référant aux Figures 2 et 3, ce ski se différencie d'un ski traditionnel selon la Figure 1 par le fait que ses chants 6, 7 comportent, incorporées et réparties à l'intérieur de leur structure, une multitude d'inclusions métalliques 11 constituées ici par des paillettes de Titane dont la longueur est typiquement comprise entre 5 et 100 µm.Referring to Figures 2 and 3, this ski is different from a ski according to Figure 1 in that its songs 6, 7 include, incorporated and distributed within their structure, a multitude of inclusions 11 formed here by titanium flakes whose length is typically between 5 and 100 microns.

Si ces chants 6, 7 sont réalisés par découpe d'une plaque 19 en composite lamifié selon la Figure 4, l'invention consiste, à la conception des plaques 19, à déposer une mince feuille de papier 16, à la recouvrir d'une couche de résine liquide thermodurcissable 17, à saupoudrer cette couche de résine liquide de paillettes métalliques 18, puis à renouveler de nombreuses fois cette opération pour obtenir un empilage de feuilles encollées, enfin à mettre sous presse cet empilage pour déclencher la polymérisation de la résine. La plaque ainsi obtenue sera ensuite découpée aux dimensions souhaitées du chant du ski.If these songs 6, 7 are made by cutting a plate 19 into composite laminated according to Figure 4, the invention consists, in the design of plates 19, to deposit a thin sheet of paper 16, to cover it with a layer thermosetting liquid resin 17, to sprinkle this layer of resin metal flake liquid 18, then to renew many times this operation to obtain a stack of sheets glued, finally to put under This stack is pressed to initiate polymerization of the resin. The plaque thus obtained will then be cut to the desired dimensions of the song of the ski.

Si les chants 6, 7 sont réalisés en un matériau polymère thermoplastique tel qu'en A.B.S., les paillettes métalliques sont incorporées aux granulés de polymère destinés à réaliser des plaques en A.B.S. par moulage, dans lesquelles seront taillés les chants ou seront obtenus des profilés par extrusion.If the edges 6, 7 are made of a polymer material As in A.B.S., the metal flakes are incorporated into the polymer granules for making A.B.S. by molding, in which will be cut the songs or will be obtained profiles by extrusion.

Compte tenu du fait que les faces latérales 8, 9 du ski sont réalisées, avec leurs classiques rebords latéraux inférieurs 12, 13, ou « débordants », par usinage des côtés latéraux du ski lors des opérations de finition consécutives au moulage du ski, les inclusions métalliques 11, 18 deviennent apparentes sur ces faces latérales, comme on le voit sur la Figure 3.In view of the fact that the lateral faces 8, 9 of the ski are made, with their classic lower side edges 12, 13, or "overflowing", by machining of the ski's lateral sides during finishing operations following the molding of the ski, the metal inclusions 11, 18 become apparent on these side faces, as seen in Figure 3.

Comme elles sont constituées d'un métal d'aspect brillant, l'effet visuel ainsi obtenu est particulièrement saisissant, cet effet visuel tendant à valoriser la qualité de ce ski.As they are made of a metal of shiny appearance, the effect This visual effect is particularly striking, this visual effect tending to value the quality of this ski.

A noter que, sur toute la surface apparente des deux débordants 12, 13, cet aspect saisissant est « rénové » à chaque affûtage des carres 3, 4 car une surface neuve des débordants 12, 13 est alors mise à nu.Note that over the entire apparent surface of the two overflowing 12, 13, this striking aspect is "renovated" with each sharpening of the edges 3, 4 because a new surface of the overflows 12, 13 is then exposed.

Le fait d'inclure des éléments métalliques de faible densité dans les éléments de renforcement latéraux a finalement pour effets :

  • d'augmenter le module d'Young des chants donc d'améliorer la résistance à l'écrasement et les résistances en flexion et torsion ;
  • d'augmenter la résistance à l'abrasion sans pénaliser l'aptitude à l'usinage du débordant ;
  • d'obtenir un effet esthétique et un aspect « technique » persistant, qu'une peinture métallisée (de surface) n'aurait pas pu assurer après usure par abrasion.
Including low density metal elements in the lateral reinforcing elements ultimately has the following effects:
  • to increase the Young's modulus of the edges thus to improve the resistance to crushing and the resistances in bending and torsion;
  • to increase the resistance to abrasion without penalizing the machining ability of the overflow;
  • to obtain an aesthetic effect and a persistent "technical" aspect, which a metallic paint (of surface) could not have ensured after wear by abrasion.

L'invention n'est pas limitée à l'exemple de réalisation qui vient d'être décrit.The invention is not limited to the embodiment which comes to be described.

Au lieu de paillettes métalliques, on peut choisir d'incorporer, dans les chants 6, 7, des billes métalliques d'un diamètre pouvant aller jusqu'à 100 µm environ.Instead of metallic flakes, one can choose to incorporate, in the edges 6, 7, metal balls with a diameter of up to 100 μm about.

Le métal constitutif de ces billes ou paillettes doit être un métal inaltérable à la corrosion, typiquement inaltérable à l'eau et à l'air. Les particules métalliques choisies doivent être inoxydables. Dans ce cas, à la différence d'autres renforts fibreux les charges métalliques sont hydrophobes, et l'on ne court donc pas le risque de détérioration des chants par infiltration d'eau, cette dernière pouvant en outre se transformer en particules de glace destructrices.The constituent metal of these beads or flakes must be a metal unalterable to corrosion, typically unalterable to water and air. The particles selected metal must be stainless. In this case, unlike other fibrous reinforcements the metal charges are hydrophobic, so we do not run the risk of deterioration of the songs by infiltration of water, the latter can also turn into destructive ice particles.

Il doit en outre avoir un aspect brillant. Pour ne pas alourdir le ski, il est préférable qu'il soit de relativement faible densité par rapport à l'acier ou les autres métaux courants.He must also have a brilliant appearance. To avoid weighing down the ski, he It is preferable that it be of relatively low density compared with steel or other common metals.

On peut bien sûr pour ceci utiliser de l'Aluminium, ou un alliage d'Aluminium, ou un alliage de Cuivre, ou, dans un mode de réalisation s'écartant de la portée de l'invention, des oxydes de Magnésium ou de Zirconium. Il est possible d'utiliser un matériau noble, tel que du Titane ou de l'Or.We can of course for this use aluminum, or an alloy aluminum, or a copper alloy, or, in an embodiment outside the scope of the invention, oxides of magnesium or Zirconium. It is possible to use a noble material, such as titanium or Gold.
