Description

La présente invention concerne les skis utilisés en sport d'hiver, et destinés à glisser sur la neige et la glace.The present invention relates to skis used in winter sports, and intended to slide on snow and ice.

Les skis généralement utilisés comportent une face inférieure de glissement se raccordant à deux faces latérales selon deux arêtes inférieures munies de carres métalliques, les faces latérales se raccordant à une face supérieure. Les skis ont une largeur relativement petite par rapport à leur longueur, leur extrémité antérieure étant recourbée vers le haut pour former une spatule. L'épaisseur du ski est généralement plus importante dans la partie centrale que dans les parties antérieure et postérieure du ski. Dans les formes conventionnelles les plus généralement utilisées, la largeur de la face inférieure du ski est plus petite dans la partie centrale que dans les parties postérieure et antérieure, la largeur étant maximale en partie antérieure du ski, c'est-à-dire au voisinage de la spatule.The skis generally used have a lower sliding face connecting to two lateral faces along two lower edges provided with metal edges, the lateral faces connecting to an upper face. The skis have a relatively small width compared to their length, their anterior end being curved upwards to form a spatula. The thickness of the ski is generally greater in the central part than in the front and rear parts of the ski. In the most generally used conventional forms, the width of the lower face of the ski is smaller in the central part than in the rear and front parts, the width being maximum in the front part of the ski, that is to say at the neighborhood of the spatula.

Dans les structures connues de ski, la face supérieure du ski est généralement une surface réglée, c'est-à-dire définie par le déplacement longitudinal d'une ligne droite transversale parallèle à la face inférieure du ski. En d'autres termes, la section transversale du ski est généralement un rectangle ou un trapèze, les grands côtés opposés du rectangle ou du trapèze étant formés par la face inférieure et la face supérieure du ski, les petits côtés opposés du rectangle ou du trapèze étant formés par les faces latérales du ski.In known ski structures, the upper face of the ski is generally a ruled surface, that is to say defined by the longitudinal displacement of a straight transverse line parallel to the lower face of the ski. In other words, the cross section of the ski is generally a rectangle or a trapezoid, the large opposite sides of the rectangle or the trapezium being formed by the lower face and the upper face of the ski, the small opposite sides of the rectangle or the trapezoid being formed by the side faces of the ski.

Le document WO 88/01190 décrit un dispositif amortisseur disposé dans des logements latéraux en dégagement par rapport à une nervure centrale surélevée du ski. Les dégagements latéraux qui reçoivent les tampons peuvent être ménagés au niveau de la ou des fixations dans l'épaisseur d'un ski classique ou provenir naturellement de la fabrication même du ski lorsqu'est prévue une saillie longitudinale centrale continue sur la longueur du ski.Document WO 88/01190 describes a damping device arranged in lateral housings in clearance with respect to an elevated central rib of the ski. The lateral clearances which receive the buffers can be provided at the level of the binding (s) in the thickness of a conventional ski or come naturally from the manufacture of the ski itself when a continuous central longitudinal projection is provided over the length of the ski.

Le document WO 87/05525 décrit un ski comprenant un corps présentant un cambre et une raideur en flexion déterminée et un insert rapporté et fixé sur la partie centrale du corps de façon à former une nervure longitudinale et à augmenter ainsi la raideur de flexion totale du ski. L'invention concerne également la méthode de production d'un ou d'une série de skis aux longueurs et raideurs adaptées à chaque catégorie de skieurs.Document WO 87/05525 describes a ski comprising a body having a camber and a determined bending stiffness and an insert inserted and fixed on the central part of the body so as to form a longitudinal rib and thus to increase the total bending stiffness of the ski. The invention also relates to the method of producing one or a series of skis with lengths and stiffnesses adapted to each category of skiers.

L'épaisseur plus importante du ski dans la zone centrale confère à cette zone centrale une rigidité accrue. Cette zone centrale est également destinée à recevoir les fixations pour l'adaptation d'une chaussure d'utilisateur. Par contre, les zones antérieure et postérieure du ski, qui présentent une épaisseur réduite, sont plus flexibles et se déforment élastiquement lors de l'utilisation du ski. Si l'on veut réaliser un ski présentant une bonne souplesse dans les zones antérieure et postérieure, il est donc nécessaire de prévoir de telles zones antérieure et postérieure présentant une épaisseur réduite.The greater thickness of the ski in the central zone gives this central zone increased rigidity. This central zone is also intended to receive the bindings for the adaptation of a user's shoe. On the other hand, the front and rear areas of the ski, which have a reduced thickness, are more flexible and elastically deform when the ski is used. If one wishes to make a ski having good flexibility in the anterior and posterior zones, it is therefore necessary to provide such anterior and posterior zones having a reduced thickness.

Un premier problème rencontré dans les structures traditionnelles de ski est que la zone centrale du ski, qui présente une épaisseur relativement importante pour lui conférer une grande rigidité, provoque un éloignement assez sensible des fixations par rapport aux arêtes inférieures du ski. Les arêtes inférieures sont les éléments qui sont destinés à mordre dans la glace, en virage. L'efficacité des arêtes inférieures munies de carres est d'autant meilleure que la liaison entre le pied de l'utilisateur et la carre est plus directe. L'éloignement entre la carre et la fixation tend à dégrader l'efficacité des carres.A first problem encountered in traditional ski structures is that the central area of the ski, which has a relatively large thickness to give it great rigidity, causes a fairly significant distance of the bindings from the lower edges of the ski. The lower edges are the elements which are intended to bite into the ice, when cornering. The effectiveness of the lower edges provided with edges is all the better as the connection between the user's foot and the edge is more direct. The distance between the edge and the binding tends to degrade the effectiveness of the edges.

Un second problème rencontré dans les structures connues de ski est que la réduction sensible de l'épaisseur des zones antérieure et postérieure du ski tend à diminuer sensiblement la masse de ces zones antérieure et postérieure, et diminue ainsi sensiblement l'inertie du ski à la fois autour d'un axe central vertical et autour d'un axe central horizontal perpendiculaires à la direction longitudinale du ski. Le moment d'inertie autour de l'axe vertical, ou axe de rotation du ski, influence le comportement du ski en rotation, en déterminant la résistance que le ski oppose à une variation de la direction du mouvement. Un ski de faible moment d'inertie, par exemple un ski court et léger à ses extrémités, est plus facile à faire tourner qu'un ski de fort moment d'inertie. Mais cette réduction du moment d'inertie diminue la stabilité du ski. Au contraire, un ski de moment d'inertie élevé est particulièrement stable en direction lors d'une descente rapide, du fait que les forces exercées latéralement sur le ski par les inégalités de la piste sont mieux absorbées en raison du plus fort moment d'inertie. D'autre part, le moment d'inertie autour de son axe horizontal central perpendiculaire à la direction longitudinale du ski influence le comportement vibratoire du ski. On sait que les vibrations peuvent être néfastes, et conduire à une perte d'adhérence au sol des arêtes inférieures du ski, et, par suite, à une instabilité directionnelle.A second problem encountered in known ski structures is that the appreciable reduction in the thickness of the anterior and posterior zones of the ski tends to significantly decrease the mass of these anterior and posterior zones, and thus significantly reduces the inertia of skiing at times around a vertical central axis and around a horizontal central axis perpendicular to the longitudinal direction of the ski. The moment of inertia around the vertical axis, or axis of rotation of the ski, influences the behavior of the ski in rotation, by determining the resistance that the ski opposes to a variation in the direction of movement. A ski with a low moment of inertia, for example a short and light ski at its ends, is easier to turn than a ski with a high moment of inertia. But this reduction in the moment of inertia decreases the stability of the ski. On the contrary, a ski with a high moment of inertia is particularly stable in direction during a rapid descent, because the forces exerted laterally on the ski by the unevenness of the track are better absorbed due to the higher moment of inertia. On the other hand, the moment of inertia around its central horizontal axis perpendicular to the longitudinal direction of the ski influences the vibratory behavior of the ski. We know that vibrations can be harmful, and lead to a loss of grip on the ground of the lower edges of the ski, and, consequently, to directional instability.

La présente invention se propose donc de remédier à ces inconvénients, par la conception d'une nouvelle forme de ski. La forme du ski est évolutive en fonction de la portion longitudinale considérée le long du ski, et cette forme évolutive est telle que l'on peut augmenter la rigidité de la zone centrale tout en réduisant la distance entre les fixations et les carres; simultanément, la forme évolutive est telle que l'on peut donner aux zones antérieure et/ou postérieure du ski une flexibilité appropriée sans réduire exagérément le moment d'inertie du ski selon un axe central vertical ou selon un axe transversal central du ski.The present invention therefore proposes to remedy these drawbacks by designing a new form of ski. The shape of the ski is scalable as a function of the longitudinal portion considered along the ski, and this scalable shape is such that the rigidity of the central zone can be increased while reducing the distance between the bindings and the edges; simultaneously, the progressive shape is such that one can give the front and / or rear areas of the ski an appropriate flexibility without excessively reducing the moment of inertia of the ski along a vertical central axis or along a central transverse axis of the ski.

La forme définie par la présente invention permet d'adapter sensiblement les caractéristiques mécaniques principales du ski en fonction du comportement recherché, et en particulier les caractéristiques d'inertie et de résistance à la flexion.The shape defined by the present invention makes it possible to substantially adapt the main mechanical characteristics of the ski in function of the desired behavior, and in particular the characteristics of inertia and resistance to bending.

Il en résulte une amélioration sensible de la conduite du ski dans les courbes et une augmentation de la longueur d'accrochage du ski sur neige. La stabilité directionnelle obtenue est similaire à celle des skis longs et lourds, sans toutefois augmenter le poids total du ski et en le maintenant à une valeur sensiblement inférieure à celle des skis lourds. Il apparaît également que le fait que les fixations puissent être solidarisées sur la face supérieure du ski à proximité immédiate des arêtes inférieures du ski améliore sensiblement la prise de carre et diminue les phénomènes vibratoires défavorables.This results in a significant improvement in the handling of the ski in curves and an increase in the length of attachment of the ski on snow. The directional stability obtained is similar to that of long and heavy skis, without however increasing the total weight of the ski and keeping it at a value significantly lower than that of heavy skis. It also appears that the fact that the bindings can be secured to the upper face of the ski in the immediate vicinity of the lower edges of the ski significantly improves the edge grip and reduces unfavorable vibration phenomena.

Pour atteindre ces objets ainsi que d'autres, le ski selon la présente invention et défini selon les termes de la revendication 1 est tel que :

  • la zone centrale de face supérieure du ski, destinée à recevoir les fixations pour l'adaptation d'une chaussure de l'utilisateur, comporte une nervure médiane surélevée, bordée de deux parties latérales abaissées, de sorte que la nervure médiane plus épaisse du ski confère à la zone centrale de ski une rigidité mécanique appropriée, tandis que les parties latérales plus minces du ski constituent des zones priviligiées d'appui de la fixation au plus près des arêtes inférieures du ski,
  • l'une au moins des zones antérieure ou postérieure de face supérieure du ski comporte une partie médiane abaissée, bordée de deux nervures latérales surélevées, de sorte que la partie médiane moins épaisse confère à la zone antérieure ou postérieure de ski une flexibilité appropriée, tandis que les nervures latérales plus épaisses du ski constituent des masses d'inertie additionnelles améliorant le comportement dynamique du ski.
To achieve these and other objects, the ski according to the present invention and defined according to the terms of claim 1 is such that:
  • the central area of the upper face of the ski, intended to receive the bindings for the adaptation of a shoe for the user, comprises a raised middle rib, bordered by two lowered lateral parts, so that the thicker middle rib of the ski gives the central ski area an appropriate mechanical rigidity, while the thinner side portions of the ski constitute privileged areas for supporting the binding as close as possible to the lower edges of the ski,
  • at least one of the anterior or posterior zones of the upper face of the ski has a lowered median part bordered by two raised lateral ribs, so that the thinner median part gives the anterior or posterior ski zone an appropriate flexibility, while that the thicker side ribs of the ski constitute additional masses of inertia improving the dynamic behavior of the ski.

Comme le représentent les figures, le ski comporte une face inférieure de glissement (1) se raccordant à deux faces latérales (2) et (3) selon deux arêtes inférieures respectives (4) et (5) munies de carres métalliques. Les faces latérales (2) et (3) se raccordent à la face supérieure (6). L'extrémité antérieure du ski est recourbée vers le haut pour former une spatule (70). L'extrémité postérieure du ski est légèrement recourbée vers le haut pour former le talon (80). Le ski peut notamment comprendre un embout de spatule (70), et un protège-talon (80), fixés par tous moyens tels que encliquetage ou collage par exemple.As shown in the figures, the ski has a lower sliding face (1) connecting to two lateral faces (2) and (3) along two respective lower edges (4) and (5) provided with metal edges. The lateral faces (2) and (3) are connected to the upper face (6). The front end of the ski is curved upward to form a spatula (70). The rear end of the ski is slightly bent upwards to form the heel (80). The ski may in particular comprise a tip tip (70), and a heel protector (80), fixed by any means such as snap-fastening or bonding for example.

Les faces latérales (2) et (3) du ski représenté sur les figures sont inclinées par rapport à la face inférieure (1) du ski, selon un angle variable en fonction de la position longitudinale considérée le long du ski. Dans le mode de réalisation représenté, les faces latérales (2) et (3) sont plus verticales par rapport à la surface de glissement (1) dans la zone centrale du ski représentée par les coupes C-C, D-D et E-E sur les figures 5, 6 et 7, tandis que dans les zones d'extrémité représentées sur les figures 3 et 9, les faces latérales (2) et (3) ont un angle d'inclinaison plus faible par rapport à la surface de glissement (1).The lateral faces (2) and (3) of the ski shown in the figures are inclined relative to the lower face (1) of the ski, at a variable angle depending on the longitudinal position considered along the ski. In the embodiment shown, the lateral faces (2) and (3) are more vertical with respect to the sliding surface (1) in the central zone of the ski represented by the sections CC, DD and EE in FIGS. 5, 6 and 7, while in the end zones shown in FIGS. 3 and 9, the lateral faces (2) and (3) have a smaller angle of inclination relative to the sliding surface (1).

On considère la zone centrale de face supérieure du ski, constituée par la partie de ski située entre le tiers et les deux tiers centrée au milieu du ski entre les zones de coupe C-C et E-E représentées sur les figures 1 et 2. Cette zone centrale du ski comprend une face supérieure, destinée à recevoir les fixations pour l'adaptation d'une chaussure d'utilisateur. La face supérieure comporte une nervure médiane (7) surélevée, bordée de deux parties latérales (8) et (9) abaissées. La nervure médiane (7) constitue une partie plus épaisse du ski, c'est à dire que la distance entre la face supérieure de nervure médiane (7) et la face inférieure (1) du ski est accentuée, pour conférer à la zone centrale du ski une rigidité mécanique appropriée. Par contre, les parties latérales (8) et (9) plus minces du ski constituent des zones priviligiées d'appui de la fixation au plus près des arêtes inférieures (4) et (5) du ski. La nervure médiane (7) comprend une face supérieure (71) sensiblement plane et de largeur L1 sensiblement constante sur une longueur L2 d'au moins 50 centimètres, de part et d'autre du plan de coupe moyen D-D, c'est à dire dans la zone destinée à recevoir les fixations. Dans cette même zone, la distance H séparant la face supérieure (71) de la nervure (7) et les faces supérieures respectives (81) et (91) des parties latérales (8) et (9) est sensiblement constante, les faces supérieures (81) et (91) étant elles-mêmes sensiblement planes. De cette façon, il est possible de régler la position longitudinale de la fixation adaptée sur la face supérieure du ski, en fonction de la taille de la chaussure de l'utilisateur. La face supérieure (71) de la nervure (7) se raccorde aux faces supérieures (81) et (91) des parties latérales abaissées (8) et (9) par des parties rayonnées (82) et (92), concaves, comme le représentent les figures 5 à 7.We consider the central area of the upper face of the ski, consisting of the ski part located between one third and two thirds centered in the middle of the ski between the cutting zones CC and EE shown in FIGS. 1 and 2. This central zone of the ski includes an upper face, intended to receive the bindings for the adaptation of a user boot. The upper face has a raised middle rib (7), bordered by two lowered side parts (8) and (9). The middle rib (7) constitutes a thicker part of the ski, that is to say that the distance between the upper face of the middle rib (7) and the lower face (1) of the ski is accentuated, to give the central area ski with adequate mechanical rigidity. On the other hand, the thinner side parts (8) and (9) of the ski constitute privileged areas for supporting the binding as close as possible to the lower edges (4) and (5) of the ski. The middle rib (7) comprises an upper face (71) substantially planar and of width L1 substantially constant over a length L2 of at least 50 centimeters, on either side of the mean cutting plane DD, that is to say in the area intended to receive the fixings. In this same zone, the distance H separating the upper face (71) of the rib (7) and the respective upper faces (81) and (91) of the lateral parts (8) and (9) is substantially constant, the upper faces (81) and (91) being themselves substantially flat. In this way, it is possible to adjust the longitudinal position of the suitable binding on the upper face of the ski, depending on the size of the shoe of the user. The upper face (71) of the rib (7) is connected to the upper faces (81) and (91) of the parts lateral lowered (8) and (9) by radiated parts (82) and (92), concave, as shown in Figures 5 to 7.

Dans le mode de réalisation représenté, les deux parties latérales abaissées (8) et (9) présentent avantageusement la même épaisseur.In the embodiment shown, the two lowered side parts (8) and (9) advantageously have the same thickness.

Dans le mode de réalisation représenté sur les figures, l'une et l'autre des zones antérieure et postérieure du ski comportent une partie médiane abaissée bordée de deux nervures latérales surélevées. Ainsi, la zone antérieure du ski, ou zone située entre la spatule (70) et le plan de coupe transversal C-C, présente une face supérieure (6) dont la partie médiane (10) est abaissée, et est bordée de deux nervures latérales (11) et (12) surélevées. Il en résulte que la partie médiane du ski est moins épaisse, et confère à la zone antérieure du ski une flexibilité appropriée, tandis que les nervures latérales plus épaisses (11) et (12) du ski constituent des masses d'inertie additionnelles améliorant le comportement dynamique du ski.In the embodiment shown in the figures, both of the front and rear zones of the ski have a lowered middle part bordered by two raised lateral ribs. Thus, the anterior zone of the ski, or zone situated between the tip (70) and the transverse cutting plane CC, has an upper face (6), the middle part (10) of which is lowered, and is bordered by two lateral ribs ( 11) and (12) raised. As a result, the middle part of the ski is thinner, and gives the front region of the ski appropriate flexibility, while the thicker lateral ribs (11) and (12) of the ski constitute additional masses of inertia improving the dynamic behavior of the ski.

De la même façon, la zone postérieure du ski, comprise entre le talon (80) et le plan de coupe F-F, présente une forme similaire avec une partie médiane (13) d'épaisseur réduite bordée de deux nervures latérales (14) et (15).In the same way, the posterior zone of the ski, comprised between the heel (80) and the cutting plane FF, has a similar shape with a median part (13) of reduced thickness bordered by two lateral ribs (14) and ( 15).

Comme le représente la figure 2 en vue de côté, la nervure médiane (7) de zone centrale se raccorde à la partie médiane (13) de zone postérieure et à la partie médiane (10) de zone antérieure du ski par une pente de raccordement progressive. De même, les parties latérales (8) et (9) de zone centrale se raccordent aux nervures latérales correspondantes (11, 12, 14 et 15) par des pentes de raccordement progressives.As shown in Figure 2 in side view, the central rib (7) in the central zone is connected to the central part (13) of the posterior zone and to the central part (10) of the anterior zone of the ski by a connection slope. progressive. Likewise, the lateral parts (8) and (9) of the central zone are connected to the corresponding lateral ribs (11, 12, 14 and 15) by progressive connection slopes.

Les nervures latérales (11, 12, 14 et 15) comportent chacune une face supérieure sensiblement plane, et les nervures latérales ont sensiblement la même épaisseur.The lateral ribs (11, 12, 14 and 15) each have a substantially planar upper face, and the lateral ribs have substantially the same thickness.

La partie médiane (10) de zone antérieure et la partie médiane (13) de zone postérieure de ski sont toutes deux sensiblement planes, ou sont tout au moins des surfaces réglées définies par des génératrices transversales parallèles à la face inférieure du ski. Elles se raccordent aux nervures latérales correspondantes par des parties rayonnées convexes (respectivement 182, 192 et 282, 292) comme le représentent les figures.The middle part (10) of the front region and the middle part (13) of the rear ski region are both substantially flat, or are at least regulated surfaces defined by transverse generatrices parallel to the underside of the ski. They are connected to the corresponding lateral ribs by convex radiated parts (respectively 182, 192 and 282, 292) as shown in the figures.

Dans la zone centrale du ski, la nervure médiane (7) présente une largeur (L1) comprise entre le quart et les trois quarts de la largeur totale de zone centrale du ski. A titre d'exemple non limitatif, un ski dont la zone centrale présente une largeur de 64 millimètres environ peut comprendre une nervure médiane (7) de largeur comprise entre 16 millimètres et 48 millimètres.In the central area of the ski, the middle rib (7) has a width (L1) of between a quarter and three quarters of the width total central ski area. By way of nonlimiting example, a ski whose central zone has a width of approximately 64 millimeters may include a middle rib (7) of width between 16 millimeters and 48 millimeters.

La partie médiane abaissée (10) de zone antérieure du ski présente une largeur (L3) comprise entre la moitié et les trois quarts de la largeur du ski dans ladite zone. Il en est de même de la partie médiane abaissée (13) de zone postérieure du ski.The lowered middle part (10) of the front region of the ski has a width (L3) of between half and three quarters of the width of the ski in said zone. It is the same for the lowered middle part (13) of the posterior region of the ski.

La forme particulière de la surface supérieure du ski, dans la zone centrale destinée à recevoir les fixations, offre également d'autres avantages. En particulier, les évidements létaraux formés par l'espace situé au-dessus des parties latérales (8) et (9) constituent deux logements pouvant recevoir une partie du mécanisme de fonctionnement des fixations et/ou des freins de ski. Par la présence de la nervure centrale (7), à un niveau plus élevé que les parties latérales (8) et (9), la surface supérieure du ski se trouve augmentée, et constitue ainsi une surface de collage accrue pour le collage éventuel des fixations. La présence de la nervure (7) constitue également un moyen de guidage pour le positionnement et la solidarisation d'une fixation sur la surface supérieure du ski.The particular shape of the upper surface of the ski, in the central zone intended to receive the bindings, also offers other advantages. In particular, the lethal recesses formed by the space located above the lateral parts (8) and (9) constitute two housings which can receive part of the mechanism for operating the bindings and / or the ski brakes. By the presence of the central rib (7), at a higher level than the lateral parts (8) and (9), the upper surface of the ski is increased, and thus constitutes an increased bonding surface for the possible bonding of the fixings. The presence of the rib (7) also constitutes a guide means for positioning and securing a binding on the upper surface of the ski.

Selon le mode de réalisation précédent, l'épaisseur "e" correspondant à la hauteur des faces latérales (2,3) du bord latéral du ski subit une variation telle que l'épaisseur "ed" est inférieure à l'épaisseur "ec" et "ee", de même que "ec" est inférieur à "eb", et "ee" inférieur à "ef". De plus, l'épaisseur "eb" est supérieure à l'épaisseur "ea" et "ef" est supérieure à "eg".According to the previous embodiment, the thickness "e" corresponding to the height of the lateral faces (2,3) of the lateral edge of the ski undergoes a variation such that the thickness "e d " is less than the thickness "e c "and" e e ", just as" e c "is less than" e b ", and" e e "less than" e f ". In addition, the thickness "e b " is greater than the thickness "e a " and "e f " is greater than "e g ".

Ainsi, et comme le montrent plus particulièrement les figures 2 et 10, les parties latérales (8) et (9) constituent des zones en creux par rapport aux nervures latérales (11,12 et 14,15) correspondantes. Mais cette disposition et la variation d'épaisseur des bords latéraux du ski peuvent être tout autrement, et notamment comme cela est représenté aux figures 11 à 18.Thus, and as shown more particularly in Figures 2 and 10, the lateral parts (8) and (9) constitute recessed areas with respect to the corresponding lateral ribs (11, 12 and 14, 15). However, this arrangement and the variation in thickness of the lateral edges of the ski can be quite different, and in particular as shown in FIGS. 11 to 18.

Selon cette variante d'exécution, les parties latérales (8) et (9) ne constituent plus des zones en creux par rapport aux nervures latérales corespondantes. A cet effet, l'épaisseur des bords latéraux diminuent progressivement vers l'avant et vers l'arrière. Ainsi,
   "ed" est supérieur à "ec"
   "ec" est supérieur à "eb"
   "eb" est supérieur à "ea"
   "ed" est supérieur à "ee"
   "ee" est supérieur à "ef"
   "ef" est supérieur à "eg".According to this alternative embodiment, the lateral parts (8) and (9) no longer constitute recessed zones relative to the corresponding lateral ribs. For this purpose, the thickness of the lateral edges gradually decrease towards the front and towards the rear. So,
"e d " is greater than "e c "
"e c " is greater than "e b "
"e b " is greater than "e a "
"e d " is greater than "e e "
"e e " is greater than "e f "
"e f " is greater than "e g ".

Cette variation d'épaisseur est donnée à titre d'exemples non limitatifs et l'on pourrait bien entendu prévoir que l'épaisseur "e" soit constante sur au moins une partie de la longueur du ski, comme par exemple dans la zone centrale.This thickness variation is given by way of nonlimiting examples and it could of course be provided for the thickness "e" to be constant over at least part of the length of the ski, as for example in the central zone.

Les figures 19 et 20 sont des vues similaires aux figures 6 et 15 représentant deux variantes de réalisation d'un ski selon l'invention. Selon ces variantes, la face supérieure (71) de la nervure (7) se raccorde aux faces supérieures (81) et (91) des parties abaissées (8) et (9) par des faces latérales (83) et (93). Selon la première de ces variantes représentée figure 19, les faces latérales (83) et (93) sont verticales ou sensiblement verticales, tandis que selon la deuxième variante représentée à la figure 20, celles-ci sont inclinées pour être convergeantes vers le haut. Notons aussi que l'inclinaison des deux faces peut être identique ou différente et que l'angle d'inclinaison A peut être variable.Figures 19 and 20 are views similar to Figures 6 and 15 showing two alternative embodiments of a ski according to the invention. According to these variants, the upper face (71) of the rib (7) is connected to the upper faces (81) and (91) of the lowered parts (8) and (9) by lateral faces (83) and (93). According to the first of these variants shown in Figure 19, the side faces (83) and (93) are vertical or substantially vertical, while according to the second variant shown in Figure 20, these are inclined to be converging upwards. Note also that the inclination of the two faces can be identical or different and that the angle of inclination A can be variable.

La structure du ski peut être du type sandwich ou du type à caisson ou de tout autre type. A la figure 21, on a représenté une structure préférée comprenant un renfort supérieur (103) rigide en forme de coque recouvrant un noyau (105), l'ensemble étant fermé à sa partie inférieure par un élément inférieur comportant les carres métalliques (50,40), une couche (100) de glissement généralement en polyéthylène, ainsi que des éléments de renfort inférieur (101,102). Une couche supérieure superficielle (104) recouvre le renfort supérieur pour former le décor du ski.The structure of the ski can be of the sandwich type or of the box type or of any other type. In FIG. 21, a preferred structure is shown comprising an upper rigid reinforcement (103) in the form of a shell covering a core (105), the assembly being closed at its lower part by a lower element comprising the metal edges (50, 40), a sliding layer (100) generally made of polyethylene, as well as lower reinforcing elements (101, 102). An upper surface layer (104) covers the upper reinforcement to form the decoration of the ski.

Les couches de renfort (101,102,103) peuvent être de tout type tels que des couches de matériaux composites comme de la fibre de verre, fibre de carbone avec de la résine époxy ou polyester, ou en alliage métallique.The reinforcing layers (101, 102, 103) can be of any type, such as layers of composite materials such as fiberglass, carbon fiber with epoxy or polyester resin, or a metal alloy.

Le noyau (105) peut être de la mousse chargée ou non, du bois ou du nid d'abeille en aluminium.The core (105) can be filled or unloaded foam, wood or aluminum honeycomb.

La couche superficielle assurant le décor peut être en polyamide ou autre, tel qu'en matériau thermoplastique. Elle peut être monocouche ou constituée de plusieurs couches. Eventuellement un insert (106) peut être ajouté, qui peut être en matériau composite ou métallique.The surface layer providing the decoration may be made of polyamide or other material, such as a thermoplastic material. It can be monolayer or made up of several layers. Optionally an insert (106) can be added, which can be of composite or metallic material.

Les couches de renfort (103) et notamment ses parois latérales (103a) et (103b) sont en matériau composite dont les renforts sont avantageusement du tissu tramé dont la trame est placée du côté du noyau (105). Ce type de disposition permet à la poutre ainsi constituée, d'avoir une meilleure résistance et tenue mécanique à la flexion et à la torsion.The reinforcing layers (103) and in particular its side walls (103a) and (103b) are made of composite material, the reinforcements of which are advantageously woven fabric, the weft of which is placed on the side of the core (105). This type of arrangement allows the beam thus formed to have better resistance and mechanical resistance to bending and torsion.

La chaussure du skieur est de façon connue en soi, retenue au ski par des fixations (17) généralement déclenchables permettant la libération du skieur lors de sollicitations trop intenses. Ces fixations sont solidaires du ski et le ski comprend généralement une fixation avant (170) ou butée retenant l'avant de la chaussure et une fixation arrière (171) ou talonnière retenant le talon de celle-ci.The skier's boot is in a manner known per se, held in ski by generally triggerable bindings (17) allowing the skier to be released during too intense stresses. These bindings are integral with the ski and the ski generally comprises a front binding (170) or stop holding the front of the boot and a rear binding (171) or heel holding the heel thereof.

Ces fixations peuvent être fixées directement sur la face supérieure (71) de la nervure (7), comme cela est représenté à la figure 22. Toutefois, il est particulièrement avantageux que les appuis soient reportés sur les faces supérieures (81) et (91) des parties latérales (8) et (9) comme cela est représenté aux figures 23 à 29.These fixings can be fixed directly to the upper face (71) of the rib (7), as shown in FIG. 22. However, it is particularly advantageous for the supports to be transferred to the upper faces (81) and (91 ) side parts (8) and (9) as shown in Figures 23 to 29.

Ainsi, selon une caractéristiques complémentaire de l'invention, le ski comprend au moins un support (16) destiné à recevoir la ou les fixations (17) de retenue de la chaussure du skieur. Cedit support (16) a la forme d'un étrier (figure 25) ayant la forme d'un "U" renversé et comprend une paroi supérieure (160) prolongée latéralement et vers le bas par deux parois latérales (161,162) pour constituer un logement (18) inférieur ayant la forme d'un profil en creux s'étendant longitudinalement destiné au passage de la nervure (7). Il faut noter qu'avantageusement, les dimensions du logement aussi bien horizontale "L4" que verticale "H4" sont supérieures aux dimensions horizontale "L1" et verticale "H" de la nervure. Selon une caractéristique de ce mode de réalisation de l'invention, la nervure (7) ne reçoit pas directement les sollicitations du skieur car le support ou l'étrier (16) est en appui uniquement sur les faces supérieures (81) et (91) des parties latérales (8) et (9).Thus, according to a complementary characteristic of the invention, the ski comprises at least one support (16) intended to receive the binding (s) (17) for retaining the skier's boot. Said support (16) has the shape of a stirrup (FIG. 25) having the shape of an inverted "U" and comprises an upper wall (160) extended laterally and downwards by two side walls (161,162) to constitute a lower housing (18) in the form of a longitudinally extending hollow profile intended for the passage of the rib (7). It should be noted that advantageously, the dimensions of the housing, both horizontal "L4" and vertical "H4" are greater than the horizontal dimensions "L1" and vertical "H" of the rib. According to a characteristic of this embodiment of the invention, the rib (7) does not directly receive the stresses of the skier because the support or the stirrup (16) is supported only on the upper faces (81) and (91 ) lateral parts (8) and (9).

A cet effet, les extrémités inférieures des parois latérales (161) et (162) du support sont reliées auxdites faces supérieures par exemple de façon rigide, par collage, par soudage ou tout autre moyen, tel que mécanique.To this end, the lower ends of the side walls (161) and (162) of the support are connected to said upper faces, for example rigidly, by gluing, by welding or any other means, such as mechanical.

Le support (16) constitue ainsi l'élément mécanique de transmission et de distribution des sollicitations du skieur au ski.The support (16) thus constitutes the mechanical element for transmitting and distributing the stresses of the skier when skiing.

Selon le mode de réalisation des figures 23 et 24, le support (16) reçoit à l'avant la fixation avant (170) et s'étend vers l'arrière jusque sous la fixation arrière (171). Ladite fixation arrière (171) appelée communément talonnière étant elle-même fixée sur la partie arrière dudit support (16).According to the embodiment of FIGS. 23 and 24, the support (16) receives the front fixing at the front (170) and extends rearwards as far as the rear fixing (171). Said rear attachment (171) commonly called heel being itself fixed on the rear part of said support (16).

La figure 26 représente une variante selon laquelle le ski comprend deux supports (16) espacés l'un de l'autre, un premier support avant (16a) sur lequel est fixée la butée avant (170) de retenue de la chaussure, et un deuxième support ou support arrière (16b) sur lequel est fixée la talonnière (171).FIG. 26 represents a variant according to which the ski comprises two supports (16) spaced from one another, a first front support (16a) on which is fixed the front stop (170) for retaining the boot, and a second support or rear support (16b) on which the heel piece (171) is fixed.

Le support (16, 16a, 16b) peut être un élément injecté en matière plastique ou un profilé métallique, un élément en plastique pultrudé ou extrudé. Bien entendu, le support (16, 16a, 16b) peut être d'une seule et même pièce ou être constitué de différentes pièces, voire même constitué par une partie de la fixation correspondante.The support (16, 16a, 16b) can be a plastic injected element or a metal profile, a pultruded or extruded plastic element. Of course, the support (16, 16a, 16b) can be in one and the same piece or be made up of different pieces, or even made up of a part of the corresponding fixing.

Notons aussi que la liaison entre le support (16, 16a, 16b) et le ski proprement dit peut être rigide comme cela est décrit précédemment, mais aussi souple. Les figures 28 et 29 représentent une telle variante dans laquelle la liaison est réalisée par un interface (19) en matériau souple.Note also that the connection between the support (16, 16a, 16b) and the ski itself can be rigid as described above, but also flexible. Figures 28 and 29 show such a variant in which the connection is made by an interface (19) of flexible material.

La liaison pourrait aussi être du type à glissière, comme cela est représenté à la figure 27, pour permettre le coulissement longitudinal éventuel du support (16) par rapport au ski. Ce coulissement longitudinal pouvant, par exemple permettre de régler et verrouiller la fixation dans la position choisie, ou encore coulisser contre l'action d'un ressort, comme il est d'usage et bien connu dans les talonnières de retenue de talon de chaussure.The connection could also be of the slide type, as shown in FIG. 27, to allow possible longitudinal sliding of the support (16) relative to the ski. This longitudinal sliding being able, for example, to adjust and lock the binding in the chosen position, or to slide against the action of a spring, as is customary and well known in the heel retaining heels of a shoe.

Les figures 30 et 31 montrent des variantes selon lesquelles l'interface souple (19) liant le support au ski a une épaisseur qui n'est pas constante. Dans la variante de la figure 30, l'épaisseur augmente vers l'avant, mais celle-ci pourrait tout aussi bien augmenter vers l'arrière. Dans la variante représentée à la figure 31, l'interface augmente en épaisseur à la fois à l'avant et à l'arrière.Figures 30 and 31 show variants according to which the flexible interface (19) connecting the support to the ski has a thickness which is not constant. In the variant of FIG. 30, the thickness increases towards the front, but this could just as easily increase towards the rear. In the variant shown in FIG. 31, the interface increases in thickness both at the front and at the rear.

La figure 32 montre une variante de réalisation du support (16a). Selon cette variante, le support est constitué de deux matériaux différents : une première partie (161) en matériau (M1) par exemple rigide et une deuxième partie (162) en un autre matériau (M2) par exemple plus souple. La partie rigide (161) comprend une partie horizontale (163) et deux parties latérales (164), la partie souple (162) étant disposée sous la partie horizontale et se trouvant du côté du centre du ski.Figure 32 shows an alternative embodiment of the support (16a). According to this variant, the support consists of two different materials: a first part (161) made of material (M1), for example rigid, and a second part (162) made of another material (M2), for example, more flexible. The rigid part (161) comprises a horizontal part (163) and two lateral parts (164), the flexible part (162) being arranged under the horizontal part and being on the side of the center of the ski.

La figure 33 montre un ski équipé du support (16a) de la figure 32. A l'arrière, le support (16b) est identique avec sa partie souple tournée du côté du centre du ski.FIG. 33 shows a ski equipped with the support (16a) of FIG. 32. At the rear, the support (16b) is identical with its flexible part turned towards the center of the ski.

La présente invention n'est pas limitée aux modes de réalisation qui ont été explicitement décrits, mais elle en inclut les diverses variantes et généralisations contenues dans le domaine des revendications ci-après.The present invention is not limited to the embodiments which have been explicitly described, but it includes the various variants and generalizations thereof contained in the field of claims below.
