Abstract
Description
L'invention concerne un ski, dont on cherche à améliorer le confort de skiabilité, notamment par diminution des vibrations engendrées, au cours de la pratique du ski, ainsi que par les réactions inhérentes aux caractéristiques mécaniques du ski lui-même.The invention relates to a ski, the aim of which is to improve the skiability comfort, in particular by reducing the vibrations generated, during skiing, as well as by the reactions inherent in the mechanical characteristics of the ski itself.
Dans le document US-A-5 232 241, on a décrit un ski dont la face supérieure présente un évidemment, destiné à recevoir une plaque au niveau de laquelle sont fixées les fixations, à savoir butée avant et talonnière arrière. De manière avantageuse, ce document prévoit qu'à l'interface entre la plaque recevant la fixation et le ski proprement dit, on intercale une feuille réalisée en un matériau visco-élastique de telle sorte à permettre, d'une part, l'absorption de vibrations gênantes, et d'autre part, à autoriser celui-ci des mouvements de flexion de relativement large amplitude, de par l'annulation, et en tout cas l'atténuation des effets de rigidité engendrés par les dispositifs de fixations traditionnels. Un tel ski est également décrit dans le document DE-A- 39 34 891, mais dans lequel la plaque n'est pas rapportée au niveau d'un évidement. Cependant, compte-tenu de la fixation de la butée et de la talonnière au niveau seulement de cette plaque rapportée, et de par la présence de ce matériau visco-élastique, on affecte de manière significative la précision de la conduite du ski, jusqu'à atteindre un certain "flottement" de la platine porte-fixation, incompatible en tout cas avec un ski de précision, a fortiori de compétition.In document US-A-5 232 241, a ski has been described, the upper face of which has a recess, intended to receive a plate at the level of which the bindings are fixed, namely front stop and rear heel. Advantageously, this document provides that at the interface between the plate receiving the binding and the ski itself, a sheet made of a visco-elastic material is interposed so as to allow, on the one hand, absorption annoying vibrations, and on the other hand, to allow it relatively large amplitude bending movements, by the cancellation, and in any case the attenuation of the effects of rigidity generated by traditional fastening devices. Such a ski is also described in document DE-A-39 34 891, but in which the plate is not attached at the level of a recess. However, taking into account the fixing of the toe piece and the heel piece only at the level of this added plate, and by the presence of this visco-elastic material, the precision of the handling of the ski is significantly affected, up to to achieve a certain "floating" of the mounting plate, incompatible in any case with a precision ski, let alone for competition.
La structure actuelle des skis tend vers une étroitisation de la zone du patin, se traduisant par un risque accru de voir porter, lors de virages, non pas les carres, mais les bords de la chaussure, qui devient ainsi nettement plus large que cette zone. Ce risque aboutit au ripage du ski, c'est à dire à son brusque décrochement par rapport à la surface de la neige.The current structure of skis tends towards a narrowing of the skate area, resulting in an increased risk of seeing, when cornering, not the edges, but the edges of the boot, which thus becomes significantly wider than this area. . This risk leads to the skidding of the ski, that is to say its abrupt withdrawal from the surface of the snow.
Afin de s'affranchir de ce risque, on a proposé de surélever la zone du patin c'est à dire la zone recevant les fixations, par rapport au plan supérieur du ski, par exemple au moyen de cales ou de plaques vissées ou collées sur la surface supérieure du ski.In order to overcome this risk, it has been proposed to raise the area of the skate, that is to say the area receiving the bindings, relative to the upper plane of the ski, for example by means of wedges or plates screwed or glued to the upper surface of the ski.
On a par exemple décrit dans le document US-A-2 550 002 un tel ski, dans lequel on surélève la zone servant au montage des fixations par une plaque en bois avec interposition entre la plaque et la surface supérieure du ski d'une lame en caoutchouc. Cependant, dans ce cas encore, on affecte de manière significative la précision de la conduite du ski, compte tenu du flottement de la plaque porte-fixations par rapport au ski lui-même.For example, such a ski has been described in document US-A-2 550 002, in which the area used for mounting the bindings is raised by a wooden plate with interposition between the plate and the upper surface of the ski with a blade made of rubber. However, in this case again, the precision of the handling of the ski is significantly affected, taking into account the floating of the binding plate relative to the ski itself.
On a également proposé, par exemple dans le document FR-A-2 648 720, de réaliser un ski, présentant au niveau de la zone du patin, une paroi supérieure surélevée, pour intégrer dans cette zone une plaque en un matériau visco-élastique. Dans une telle structure, l'isolation des vibrations n'est cependant pas optimale.It has also been proposed, for example in document FR-A-2 648 720, to make a ski, having at the level of the skate area, a raised upper wall, to integrate into this area a plate made of a visco-elastic material . In such a structure, the vibration isolation is however not optimal.
Parallèlement, de tels systèmes sont inenvisageables avec un ski à profil plus complexe, dont l'évolution est sans cesse croissante et dont le public est de plus en plus demandeur.At the same time, such systems are unthinkable with a ski with a more complex profile, the evolution of which is constantly increasing and for which the public is increasingly demanding.
L'objet de l'invention est de proposer un ski du type en question, s'affranchissant de ces différents inconvénients.The object of the invention is to provide a ski of the type in question, overcoming these various drawbacks.
Elle propose un ski comprenant :
- une semelle de glisse, éventuellement bordée par des carres,
- un corps structurel comprenant au moins une couche supérieure de renfort recouverte d'une surface supérieure de protection,
- au niveau de la zone du patin, une structure rapportée, solidarisée par collage sur ladite surface supérieure, par l'intermédiaire d'une feuille ou plaque réalisée en un matériau visco-élastique, au moins en partie arrière, c'est à dire au niveau de la zone destinée à recevoir la talonnière assurant en coopération avec une butée la fixation de la chaussure du skieur.
- a gliding sole, possibly bordered by edges,
- a structural body comprising at least one upper reinforcing layer covered with an upper protective surface,
- at the level of the pad area, an attached structure, secured by bonding to said upper surface, by means of a sheet or plate made of a visco-elastic material, at least in part rear, that is to say at the level of the zone intended to receive the heel piece ensuring, in cooperation with a stop, the fixing of the skier's shoe.
Le ski selon l'invention se caractérise en ce que les vis de fixation de la zone antérieure de la structure rapportée traversent celle-ci pour venir s'ancrer dans la couche supérieure de renfort du corps structurel, alors que les vis de fixation de la talonnière ne viennent s'ancrer que dans la structure rapportée, au-dessus de la feuille ou plaque en matériau visco-élastique.The ski according to the invention is characterized in that the fixing screws of the anterior zone of the attached structure pass through it to come to anchor in the upper reinforcement layer of the structural body, while the fixing screws of the heel piece is anchored only in the attached structure, above the sheet or plate of visco-elastic material.
De la sorte, il est ainsi possible de cumuler d'une part, la fonction amortissante du matériau visco-élastique, fonctionnant soit par écrasement, soit par cisaillement, et d'autre part, la fonction de précision de guidage du ski par la butée avant. Par ailleurs, compte tenu de la possibilité de cisaillement conférée à la zone postérieure de la structure rapportée, de par la présence au niveau de sa fixation sur le corps structurel du ski d'une feuille ou plaque en matériau visco-élastique, l'ensemble de la fixation butée avant + talonnière n'est jamais comprimé, même en cas de fléchissement du ski.In this way, it is thus possible to combine, on the one hand, the damping function of the visco-elastic material, operating either by crushing or by shearing, and, on the other hand, the precision function of guiding the ski by the stop. before. In addition, taking into account the possibility of shearing conferred on the posterior zone of the added structure, due to the presence at its level of attachment to the structural body of the ski of a sheet or plate of visco-elastic material, the assembly of the front toe + heel piece binding is never compressed, even if the ski bends.
Avantageusement, la structure rapportée présente une surface supérieure prolongeant la forme générale de la surface supérieure du ski. En d'autres termes, on n'observe pas de discontinuité marquée dans le profil du ski, après mise en place de ladite structure rapportée, et ce, tant dans la direction longitudinale, que dans la direction transversale du ski.Advantageously, the added structure has an upper surface extending the general shape of the upper surface of the ski. In other words, there is no marked discontinuity in the profile of the ski, after the said added structure has been put in place, both in the longitudinal direction and in the transverse direction of the ski.
Avantageusement, la butée et la talonnière sont maintenues sensiblement parallèles à la semelle au moyen d'éléments rapportés sur ladite structure et de forme appropriée complémentaire pour s'adapter au profil particulier de cette structure, notamment lorsque celle-ci présente une section transversale globalement triangulaire.Advantageously, the toe piece and the heel piece are kept substantially parallel to the sole by means of elements attached to said structure and of a suitable complementary shape to adapt to the particular profile of this structure, in particular when the latter has a generally triangular cross section. .
La manière dont l'invention peut être réalisée et les avantages qui en découlent ressortiront mieux des exemples de réalisation qui suivent, donnés à titre indicatif et non limitatif à l'appui des figures annexées.The manner in which the invention can be implemented and the advantages which ensue therefrom will emerge more clearly from the following exemplary embodiments, given by way of indication and without limitation in support of the appended figures.
La figure 1 est une représentation schématique en perspective d'un ski conforme à l'invention.Figure 1 is a schematic perspective representation of a ski according to the invention.
La figure 2 est une représentation partielle en section longitudinale selon la ligne II-II de la figure 1, notamment de la zone du patin du ski conformément à l'invention.Figure 2 is a partial representation in longitudinal section along the line II-II of Figure 1, in particular of the ski skid area according to the invention.
Les figures 3 et 4 sont des représentations schématiques en section transversale d'un ski, d'une part au niveau de la butée avant selon la ligne III-III de la figure 2, et d'autre part, au niveau de la talonnière selon la ligne IV-IV de ladite figure 2.Figures 3 and 4 are schematic representations in cross section of a ski, on the one hand at the front stop along line III-III of Figure 2, and on the other hand, at the heel according line IV-IV of said figure 2.
La figure 5 est une représentation schématique en perspective d'un ski à profil particulier, selon l'invention.Figure 5 is a schematic perspective representation of a ski with a particular profile, according to the invention.
Les figures 6 et 7 sont des représentations schématiques en section transversale analogues aux figures 3 et 4, mais d'un ski à profil particulier selon la figure 5.FIGS. 6 and 7 are schematic representations in cross section similar to FIGS. 3 and 4, but of a ski with a particular profile according to FIG. 5.
La figure 1 représente très schématiquement un ski (1) de profil traditionnel, et qui comporte au niveau du patin (2) une structure (3) rapportée sur la face supérieure dudit ski au niveau de ce patin. Ce ski comporte en outre une semelle de glisse (13), bordée par des carres latérales métalliques (16), le sous-ensemble semelle ainsi réalisé étant recouvert d'un élément de renfort (12). Par ailleurs, le ski représenté comporte également des chants latéraux (17), par exemple réalisés en ABS (acryl-butyl-styrène).FIG. 1 very schematically represents a ski (1) of traditional profile, and which comprises at the level of the skate (2) a structure (3) attached to the upper face of said ski at the level of this skate. This ski also comprises a gliding sole (13), bordered by metal lateral edges (16), the sole subassembly thus produced being covered with a reinforcing element (12). Furthermore, the ski shown also has lateral edges (17), for example made of ABS (acryl-butyl-styrene).
Plus spécifiquement, la structure (3), dont on a représenté sur les figures 2, 3 et 4 un mode de réalisation, est par exemple réalisée en bois, en plastique moulé, ou encore selon une structure plus complexe. Par ailleurs, bien que représentée sous forme monobloc dans les figures, cette structure rapportée (3) peut être constituée de deux parties, respectivement une partie antérieure et une partie postérieure.More specifically, the structure (3), an embodiment of which has been shown in FIGS. 2, 3 and 4, is for example made of wood, molded plastic, or else according to a more complex structure. Furthermore, although shown in one-piece form in the figures, this added structure (3) may consist of two parts, respectively an anterior part and a posterior part.
Une feuille ou plaque (8) d'un matériau visco-élastique est intercalée entre la structure (3) et la face supérieure (9) du ski (1). Il est à noter que si dans les exemples décrits en liaison avec les figures, cette feuille ou plaque en matériau visco-élastique s'étend selon toute la longueur de la structure rapportée (3), ladite feuille (8) peut être limitée à la seule zone postérieure de la structure rapportée (3), c'est à dire au niveau de la zone de fixation de la talonnière (7).A sheet or plate (8) of a visco-elastic material is interposed between the structure (3) and the upper face (9) of the ski (1). It should be noted that if in the examples described in connection with the figures, this sheet or plate of visco-elastic material extends along the entire length of the attached structure (3), said sheet (8) can be limited to the single posterior zone of the attached structure (3), that is to say at the level of the heel attachment zone (7).
Cette structure (3), qui peut être de profil variable, reçoit deux éléments respectivement (4) et (5) à l'aplomb du lieu d'implantation de la fixation, à savoir de la butée avant (6) et de la talonnière (7). Ces éléments (4) et (5), par exemple réalisés en polyuréthane, sont destinés à permettre le positionnement de ladite fixation selon un plan parallèle à la semelle au niveau du patin (2). Leur fixation sur la structure (3) s'effectue au moyen de vis d'ancrage ou système équivalent (14, 15) (figures 3 et 4).This structure (3), which can be of variable profile, receives two elements respectively (4) and (5) directly above the location of the binding, namely the front stop (6) and the heel piece (7). These elements (4) and (5), for example made of polyurethane, are intended to allow the positioning of said attachment along a plane parallel to the sole at the level of the shoe (2). They are fixed to the structure (3) by means of anchoring screws or equivalent system (14, 15) (Figures 3 and 4).
Selon une caractéristique de l'invention, la fixation de la butée (6) sur l'élément (4) au niveau de la structure (3) au moyen des vis (14) s'ancre plus profondement que la structure (3) elle-même, puisqu'elle vient s'ancrer au niveau de la zone supérieure du ski (1) tel qu'on peut bien l'observer sur la figure 3, et ce, en traversant la plaque visco-élastique (8), puis la feuille de protection de la surface supérieure du ski, faisant en outre office de décor (9), pour se visser dans l'élément supérieur de renfort (10) et dans le noyau (11), constituant l'âme du corps structurel du ski.According to a characteristic of the invention, the fixing of the stop (6) on the element (4) at the level of the structure (3) by means of the screws (14) is anchored more deeply than the structure (3) it -same, since it comes to be anchored at the upper zone of the ski (1) as can be observed in FIG. 3, and this, by crossing the visco-elastic plate (8), then the protective sheet of the upper surface of the ski, also serving as a decoration (9), to be screwed into the upper reinforcing element (10) and into the core (11), constituting the core of the structural body of the ski.
En revanche, la talonnière (7) fixée sur l'élément (5) ne vient s'ancrer qu'au niveau de la structure (3), tel qu'on peut mieux l'observer sur la figure 4, donc sans atteindre la feuille (9) de protection de la surface supérieure du ski, et a fortiori sans atteindre le corps structurel dudit ski.On the other hand, the heel piece (7) fixed on the element (5) is only anchored at the level of the structure (3), as can be better seen in FIG. 4, therefore without reaching the sheet (9) for protecting the upper surface of the ski, and a fortiori without reaching the structural body of said ski.
De la sorte, la structure (3) est isolée du corps du ski par la présence de la plaque de matériau visco-élastique (8), de sorte qu'un grand nombre de vibrations sont absorbées par ce matériau et ne sont pas transmises au skieur.In this way, the structure (3) is isolated from the ski body by the presence of the plate of visco-elastic material (8), so that a large number of vibrations are absorbed by this material and are not transmitted to the skier.
En revanche, de par l'ancrage profond de la butée avant (6) au moyen des vis (14) au niveau de la face supérieure du ski (9) et du renfort (10), on confére de la sorte une plus grande précision dans la conduite du ski, notamment en virage.On the other hand, due to the deep anchoring of the front stop (6) by means of the screws (14) at the level of the upper face of the ski (9) and of the reinforcement (10), this gives greater precision. when driving the ski, especially when cornering.
Ainsi, la zone postérieure de la structure rapportée (3) est fixée par collage sur la face supérieure de la feuille ou plaque (8) en visco-élastique, elle même collée par sa surface inférieure sur le corps structurel du ski. De la sorte, la talonnière, fixée à l'aplomb de cette zone sur la seule structure rapportée, est à même de permettre l'occurence de cisaillement, de par le feuille visco-élastique (8).Thus, the posterior zone of the attached structure (3) is fixed by gluing to the upper face of the sheet or plate (8) in visco-elastic, itself glued by its lower surface to the structural body of the ski. In this way, the heel piece, fixed to the plumb of this zone on the only added structure, is able to allow the occurrence of shearing, by the visco-elastic sheet (8).
On a représenté sur les figures 5 à 7 une autre forme de réalisation de l'invention, dans laquelle le profil du ski (18) n'est pas traditionnel, comme représenté sur la figure 1, mais est complexe et notamment présente une section triangulaire variant tout au long de la longueur du ski.Another embodiment of the invention is shown in FIGS. 5 to 7, in which the profile of the ski (18) is not traditional, as shown in FIG. 1, but is complex and in particular has a triangular section. varying throughout the length of the ski.
Le profil de la surface supérieure de ce ski (18) forme deux pans (19, 20), d'inclinaison variable sur la longueur du ski, lesdits pans se rejoignant en formant une arête supérieure (21). Au niveau du patin, ainsi que l'on peut l'observer sur les figures 6 et 7, la section du ski est sensiblement trapézoïdale, et est surmontée d'une structure rapportée (22) de section triangulaire, prolongeant la forme des côtés de la section trapézoïdale, de telle sorte à conférer au ski un profil triangulaire continu, exempt de discontinuités de forme.The profile of the upper surface of this ski (18) forms two sections (19, 20), of variable inclination over the length of the ski, said sections joining together forming an upper edge (21). At the level of the skate, as can be seen in FIGS. 6 and 7, the section of the ski is substantially trapezoidal, and is surmounted by an attached structure (22) of triangular section, extending the shape of the sides of the trapezoidal section, so as to give the ski a continuous triangular profile, free of discontinuities in shape.
Au niveau de la zone du patin, le ski reçoit entre sa face supérieure, constituée par la petite base de la section trapézoïdale, et la structure rapportée (22), une bande (8) réalisée en un matériau visco-élastique.At the level of the skate area, the ski receives between its upper face, constituted by the small base of the trapezoidal section, and the attached structure (22), a strip (8) made of a visco-elastic material.
De la sorte, et dans ce cas, les éléments (4) et (5) présentent une forme adaptée et complémentaire au profil considéré, de sorte à maintenir dans le même plan parallèle à la semelle au niveau du patin, respectivement la butée avant (6) et la talonnière (7).In this way, and in this case, the elements (4) and (5) have a shape adapted and complementary to the profile considered, so as to maintain in the same plane parallel to the sole at the level of the shoe, respectively the front stop ( 6) and the heel piece (7).
Le mode de fixation demeure équivalent, à savoir ancrage profond des vis (14) traversant l'élément (4) recevant la butée avant (6), à l'intérieur de la face supérieure du ski (18), et notamment au niveau du renfort (10), et ancrage limitée des vis (15) traversant l'élément (5) support de la talonnière (7) à l'intérieur de la seule structure rapportée (22), afin de permettre les phénomènes de cisaillement à ce niveau.The method of attachment remains equivalent, namely deep anchoring of the screws (14) passing through the element (4) receiving the front stop (6), inside the upper face of the ski (18), and in particular at the level of the reinforcement (10), and limited anchoring of the screws (15) passing through the element (5) supporting the heel piece (7) inside the single added structure (22), in order to allow shearing phenomena at this level .
Outre les avantages déjà développés dans le cadre de la description de l'exemple de réalisation se rapportant aux figures 1 à 4, cette forme particulière de réalisation permet d'obtenir un bon guidage latéral des éléments intermédiaires (4, 5), et partant de la butée avant (6) et de la talonnière (7), par rapport à l'axe longitudinal du ski, ce guidage étant en effet optimisé par le profil particulier en forme de nervure du ski, aboutissant à une coopération plus étroite entre lesdits éléments (4, 5) et la surface supérieure du ski.In addition to the advantages already developed in the context of the description of the exemplary embodiment relating to FIGS. 1 to 4, this particular embodiment makes it possible to obtain good lateral guidance of the intermediate elements (4, 5), and therefore the front stop (6) and the heel piece (7), with respect to the longitudinal axis of the ski, this guidance being in fact optimized by the particular rib-shaped profile of the ski, resulting in closer cooperation between said elements (4, 5) and the upper surface of the ski.
