Description

La présente invention se rapporte à un ski, tel qu'un ski alpin, un ski de fond, un monoski ou un surf pour neige. Elle concerne plus particulièrement un perfectionnement à ce type de skis.The present invention relates to a ski, such as an alpine ski, a cross-country ski, a monoski or a snowboard. It relates more particularly to an improvement to this type of skis.

Il est connu de réaliser le corps du ski grâce à une structure plus ou moins souple.It is known to make the body of the ski thanks to a more or less flexible structure.

On connait déjà différents types de ski et il en existe de très nombreuses variantes. Ceux-ci sont constitués par une poutre de forme allongée dont l'extrémité avant est courbée vers le haut pour constituer une spatule, l'extrémité arrière l'étant aussi plus légèrement pour constituer le talon.We already know different types of ski and there are many variations. These consist of an elongated beam, the front end of which is curved upwards to form a spatula, the rear end also being more slightly to form the heel.

Les skis actuels ont généralement une structure composite dans laquelle sont combinés différents matériaux de manière que chacun d'eux intervienne de façon optimale, compte-tenu de la distribution des contraintes mécaniques lors de l'utilisation du ski. Ainsi, la structure comprend généralement des éléments de protection périphériques, des éléments internes de résistance pour résister aux contraintes de flexion et de torsion, et un noyau. Ces éléments sont assemblés par collage ou par injection, l'assemblage s'effectuant généralement à chaud dans un moule présentant la forme définitive du ski, avec une partie avant fortement relevée en spatule, une partie arrière légèrement relevée en talon, une partie centrale cambrée.Current skis generally have a composite structure in which different materials are combined so that each of them intervenes optimally, taking into account the distribution of mechanical stresses when using the ski. Thus, the structure generally comprises peripheral protective elements, internal resistance elements to resist the flexural and torsional stresses, and a core. These elements are assembled by gluing or by injection, the assembly generally being carried out hot in a mold having the final shape of the ski, with a front part strongly raised in a tip, a rear part slightly raised in the heel, a central arched part. .

Malgré le souci des constructeurs de fabriquer des skis de bonne qualité, ceux-ci n'ont pas, à ce jour trouvé un ski de haute performance satisfaisant dans toutes les conditions d'utilisation.Despite the manufacturers' concern to manufacture good quality skis, they have not, to date found a high performance ski satisfactory in all conditions of use.

Les skis actuels présentent un certain nombre d'inconvénients et en particulier, celui du mauvais comportement lors des oscillations dues aux vibrations ou aux flexions du ski. En effet, les vibrations persistantes provoquent une perte d'adhérence et donc, une mauvaise conduite du ski. Il est donc très important d'amortir les vibrations, ainsi il a déjà été proposé des solutions. Notons par exemple les solutions proposées dans les demandes de brevet français n° 2 503 569 et 2 575 393. Mais ces dispositifs d'amortissement n'ont en fait que des effets tout à fait mineurs et imperceptibles pour le skieur.Current skis have a number of drawbacks and in particular that of poor behavior during oscillations due to vibrations or flexing of the ski. Indeed, the persistent vibrations cause a loss of grip and therefore, poor handling of the ski. It is therefore very important to dampen vibrations, so solutions have already been proposed. Note, for example, the solutions proposed in French patent applications Nos. 2,503,569 and 2,575,393. However, these damping devices have in fact only very minor and imperceptible effects for the skier.

La présente invention veut remédier aux différents inconvénients évoqués précédemment et propose une solution particulièrement simple, efficace et fiable aux problèmes d'amortissement des vibrations.The present invention seeks to remedy the various drawbacks mentioned above and proposes a particularly simple, effective and reliable solution to the problems of damping vibrations.

Ainsi, le dispositif destiné à amortir les vibrations d'un ski, selon l'invention est caractérisé en ce qu'il est constitué par au moins une lame de flexion reliée au ski par un moyen de liaison rigide et au moins un moyen de liaison souple, cesdits moyens étant espacés longitudinalement l'un de l'autre sur ladite lame.Thus, the device intended to dampen the vibrations of a ski, according to the invention is characterized in that it is constituted by at least one flexion blade connected to the ski by a rigid connection means and at least one connection means flexible, said means being spaced longitudinally from one another on said blade.

Selon des caractéristiques complémentaires, la lame de flexion comprend à l'une au moins de ses extrémités un moyen de liaison souple.et à l'autre de ses extrémités un moyen de liaison rigide..According to additional characteristics, the bending blade comprises at one of its ends a flexible connection means. And at the other of its ends a rigid connection means.

Selon une disposition particulière, la lame de flexion est une lame en aluminium ou en matériau composite.According to a particular arrangement, the bending blade is an aluminum or composite material blade.

   Selon des dispositions particulières, la lame de flexion est fixée à la surface supérieure du ski ou dans sa structure.The invention also relates to a ski equipped with the device according to the invention
According to particular provisions, the flexion blade is fixed to the upper surface of the ski or in its structure.

Le ski (1) comprenant le dispositif est constitué par une poutre allongée ayant sa propre distribution d'épaisseur, de largeur et donc sa propre raideur. Il comprend une partie centrale (2) appelée aussi zone de montage des fixations (3, 4) destinées à retenir la chaussure sur le ski, la fixation avant (3) étant communément appelée butée, tandis que la fixation arrière (4) est appelée généralement talonnière. L'extrémité avant (5) du ski (1) est relevée pour former la spatule (6), tandis que l'extrémité arrière (7) l'est aussi pour former le talon (8) du ski. La poutre comprend par ailleurs une surface inférieure de glissement (9) et une surface supérieure (10). Notons que le contact de la surface inférieure (9) avec la neige se fait entre le point de contact avant (11) et le point de contact arrière (12) correspondant aux endroits où ladite surface inférieure commence à se relever.The ski (1) comprising the device consists of an elongated beam having its own distribution of thickness, of width and therefore its own stiffness. It comprises a central part (2) also called a mounting area for the bindings (3, 4) intended to retain the boot on the ski, the front binding (3) being commonly called a stop, while the rear binding (4) is called generally heel. The front end (5) of the ski (1) is raised to form the tip (6), while the rear end (7) is also raised to form the heel (8) of the ski. The beam further comprises a lower sliding surface (9) and an upper surface (10). Note that the contact of the lower surface (9) with the snow takes place between the front contact point (11) and the rear contact point (12) corresponding to the places where said lower surface begins to rise.

Selon les premiers modes de réalisation représentés aux figures 1 à 25, le dispositif d'amortissement selon l'invention est constitué par une lame de flexion (13, 13a, 13b) disposée sur la surface supérieure (10) du ski en dehors de sa structure proprement dite.According to the first embodiments shown in FIGS. 1 to 25, the damping device according to the invention consists of a bending blade (13, 13a, 13b) disposed on the upper surface (10) of the ski outside of its structure itself.

Selon une caractéristique de l'invention, la lame est reliée au ski par des moyens de liaison rigide (15, 150) et au moins des moyens de liaison souple (17, 18, 180) espacés longitudinalement desdits moyens de liaison rigide (15, 150).According to a characteristic of the invention, the blade is connected to the ski by rigid connection means (15, 150) and at least means for flexible connection (17, 18, 180) spaced longitudinally of said rigid connection means (15, 150).

Les figures 1 à 10 montrent une première variante selon laquelle le dispositif d'amortissement est tel que c'est l'extrémité arrière (130) de la lame de flexion (13) qui est fixée au ski dans la zone centrale (2), et s'étend vers l'avant (AV). La lame de flexion (13) est par exemple constituée par une bande d'aluminium d'épaisseur "e1" comprise entre 1 et 5 millimètres, de largeur "l1" comprise entre 10 et 60 millimètres et de longueur comprise entre 100 et 1200 millimètres.. Son extrémité arrière (130) est fixée rigidement au ski au niveau de la butée (3) par des moyens de liaison rigide. Ainsi, l'extrémité arrière (130) de la bande en aluminium est par exemple disposée sous la plaque de base (14) de la fixation (3) et retenue avec elle par les vis (15). A cet effet, l'extrémité (130) de la bande se termine par une partie élargie (130') comprenant des trous (16) permettant le passage des vis de fixations (15). Selon l'invention l'extrémité avant (131) de la lame de flexion (13) est liée à la surface supérieure du ski par des moyens d'amortissement (17) constituant les moyens de liaison souple. Ainsi, on a disposé entre l'extrémité avant (131) de la lame de flexion (13) et le ski, une interface (18) réalisée par une couche d'un matériau souple du type élastique et notamment de type viscoélastique. Cette couche d'épaisseur "e2" comprise entre 0,5 et 4 millimètres est collée ou soudée d'une part sous la surface inférieure (132) de la lame et d'autre part sur la surface supérieure (10) dudit ski (1). Elle peut avoir la même largeur "l2" que la largeur "l1" de la lame et une longueur "L2" comprise entre 2 et 15 centimètres. On notera que les moyens de liaison rigide (15) sont espacés longitudinalement d'une distance "D" des moyens de liaison souple (17).FIGS. 1 to 10 show a first variant according to which the damping device is such that it is the rear end (130) of the flexion blade (13) which is fixed to the ski in the central zone (2), and extends forward (AV). The bending blade (13) is for example constituted by an aluminum strip of thickness "e 1" between 1 and 5 millimeters, of width "l 1" between 10 and 60 millimeters and of length between 100 and 1200 millimeters .. Its rear end (130) is rigidly fixed to the ski at the stop (3) by rigid connection means. Thus, the rear end (130) of the aluminum strip is for example placed under the base plate (14) of the fixing (3) and retained with it by the screws (15). To this end, the end (130) of the strip ends in an enlarged part (130 ') comprising holes (16) allowing the passage of the fixing screws (15). According to the invention, the front end (131) of the flexion blade (13) is linked to the upper surface of the ski by damping means (17) constituting the flexible connection means. Thus, there is disposed between the front end (131) of the flexion blade (13) and the ski, an interface (18) produced by a layer of a flexible material of the elastic type and in particular of the viscoelastic type. This layer of thickness "e 2" between 0.5 and 4 millimeters is glued or welded on the one hand under the lower surface (132) of the blade and on the other hand on the upper surface (10) of said ski ( 1). It can have the same width "l2" as the width "l 1" of the blade and a length "L 2" of between 2 and 15 centimeters. It will be noted that the rigid connection means (15) are spaced longitudinally by a distance "D" from the flexible connection means (17).

Le matériau utilisé peut être élastique d'une densité de 10 à 85 shores A ou du matériau viscoélastique de module d'élasticité de 15 à 160 mégapascal, d'une dureté de 50 à 95 shores A et d'une valeur d'amortissement de 0,13 à 0,72. Bien entendu, ces données ne sont que des exemples de réalisation, pour une température de 20 degrés et une fréquence de 15 Herz. La fixation de l'interface (18) sur la lame (13) et sur la surface supérieure du ski est réalisée soit par une résine thermodurcissable du type epoxyde poylester, vinylester ou polyuréthane, soit par un film thermoplastique ou tout autre moyen. Bien entendu, il est possible de fixer l'extrémité arrière (130) de la lame de façon indépendante et indépendamment de la butée (3), comme cela est représenté aux figures 6 et 7. A la figure 6, la lame est fixée devant la butée, tandis qu'à la figure 7, elle est fixée derrière. Dans ce cas, la lame (13) passe librement sous la plaque de base (14) de ladite butée (voir figure 8). A cet effet, la surface inférieure de la plaque de base comprend un profil en creux (140) dont les dimensions sont supérieures aux dimensions de la lame (13) pour en permettre le passage et le libre mouvement. La lame étant alors fixée directement au ski par des vis (150) dans la zone comprise entre la fixation avant (3) et la fixation arrière (4).The material used can be elastic with a density of 10 to 85 shores A or a viscoelastic material with a modulus of elasticity of 15 to 160 megapascals, a hardness of 50 to 95 shores A and a damping value of 0.13 to 0.72. Of course, these data are only exemplary embodiments, for a temperature of 20 degrees and a frequency of 15 Herz. The interface (18) is fixed to the blade (13) and to the upper surface of the ski either by a thermosetting resin of the poylester, vinylester or polyurethane epoxy type, or by a thermoplastic film or any other means. Of course, it is possible to fix the rear end (130) of the blade independently and independently of the stop (3), as shown in Figures 6 and 7. In Figure 6, the blade is fixed in front the stop, while in Figure 7, it is fixed behind. In this case, the blade (13) passes freely under the base plate (14) of said stop (see Figure 8). For this purpose, the lower surface of the base plate includes a hollow profile (140) whose dimensions are greater than the dimensions of the blade (13) to allow passage and free movement. The blade is then fixed directly to the ski by screws (150) in the area between the front binding (3) and the rear binding (4).

On peut aussi fixer la lame de flexion (13) à la surface supérieure (10) du ski (1) parcollage ou soudage.It is also possible to fix the bending blade (13) to the upper surface (10) of the ski (1) for gluing or welding.

Les figures 9, 9a, 10, 10a représentent schématiquement le fonctionnement de l'amortissement. La figure 9 montre le ski à l'état de repos et la figure 10, en cours de flexion. Au repos, le point "a" de l'extrémité avant (131) de la lame de flexion correspond à un point "b" de la surface supérieure (10) du ski. Au cours de la flexion (figure 10), on constate qu'il y a déplacement relatif longitudinal (d) entre les points "a" et "b". Au cours de ce déplacement, il y a cisaillement de la couche de matériau souple et donc amortissement. Le choix du matériau de l'interface et de ses dimensions déterminant les conditions d'amortissement.Figures 9, 9a, 10, 10a schematically show the operation of depreciation. Figure 9 shows the ski in the rest state and Figure 10, during bending. At rest, the point "a" of the front end (131) of the flexion blade corresponds to a point "b" of the upper surface (10) of the ski. During bending (FIG. 10), it is noted that there is a relative longitudinal displacement (d) between the points "a" and "b". During this displacement, there is shearing of the layer of flexible material and therefore damping. The choice of interface material and its dimensions determining the depreciation conditions.

Bien entendu, le dispositif d'amortissement peut être disposé à l'arrière du ski, comme cela est représenté aux figures 11 et 12. Ainsi selon cette variante, la lame (13) de flexion est fixée au ski de façon rigide par son extrémité avant (131) et s'étend vers l'arrière. L'extrémité arrière (130) de la lame étant quant à elle liée au ski par des moyens d'amortissement (17) constitués comme précédemment par une interface (18) en matériau souple.Of course, the damping device can be arranged at the rear of the ski, as shown in FIGS. 11 and 12. Thus according to this variant, the flexion blade (13) is fixed to the ski rigidly by its end. front (131) and extends rearward. The rear end (130) of the blade being linked to the ski by damping means (17) constituted as before by an interface (18) made of flexible material.

Il va de soi que le ski peut comprendre à la fois une lame de flexion avant (13a) et une lame de flexion arrière (13b), comme cela est représenté aux figures 13 et 14.It goes without saying that the ski can comprise both a front bending blade (13a) and a rear bending blade (13b), as shown in FIGS. 13 and 14.

Les figures 15 et 16 représentent un autre mode de réalisation selon lequel la lame de flexion (13) est fixée à l'avant du ski par son extrémité avant (131) grâce à des vis (150). La lame (13) s'étendant alors vers l'arrière et son extrémité arrière (130) est liée au ski et plus précisément à sa surface supérieure (10) par des moyens d'amortissement (17) qui sont identiques à ceux décrits précédemment, c'est à dire par une interface collée (18) en matériau souple.Figures 15 and 16 show another embodiment according to which the flexion blade (13) is fixed to the front of the ski by its front end (131) by means of screws (150). The blade (13) then extending rearward and its rear end (130) is linked to the ski and more precisely at its upper surface (10) by damping means (17) which are identical to those described above, that is to say by a bonded interface (18) made of flexible material.

Les figures 17 et 18 montrent une autre variante selon laquelle la lame (13) est fixée sur l'arrière du ski par des vis (150) et s'étend vers l'avant pour être reliée au ski par une interface (18) dans une zone située derrière la talonnière.Figures 17 and 18 show another variant in which the blade (13) is fixed to the rear of the ski by screws (150) and extends forward to be connected to the ski by an interface (18) in an area behind the heel.

Il va de soi que dans les modes de réalisation des figures 15 à 18, les lames flexion peuvent être plus ou moins longues.It goes without saying that in the embodiments of FIGS. 15 to 18, the bending blades can be more or less long.

Ainsi, la lame (13) de la figure 19 est engagée librement sous la butée (3) pour s'étendre au-delà de celle-ci, pour être liée élastiquement au ski. A cet effet, la plaque de base (14) comprend un profil en creux (140) dont les dimensions permettent le passage et le libre mouvement de la lame de flexion (13).Thus, the blade (13) of Figure 19 is freely engaged under the stop (3) to extend beyond the latter, to be linked elastically to the ski. To this end, the base plate (14) comprises a hollow profile (140) whose dimensions allow the passage and the free movement of the bending blade (13).

Les figures 21 à 24 représentent une variante selon laquelle il y a multiplication des effets longitudinaux dus aux flexions du ski. A cet effet, le ski comprend deux lames de flexion (13a, 13b): une première lame de flexion avant (13a) et une deuxième lame de flexion arrière (13b). La lame de flexion avant (13a) est fixée au ski devant la butée (3) par son extrémité avant (131a) grâce à des vis (150) et s'étend vers l'arrière en passant librement sous ladite butée (3). De même, la lame de flexion arrière (13b) est fixée au ski derrière la talonnière (4) par son extrémité arrière (130b) pour s'étendre vers l'avant en passant librement sous ladite talonnière (4) jusque dans la zone centrale (2) entre les deux fixations (3, 4). On constate qu'il y a recouvrement des deux extrémités. L'extrémité arrière (130a) de la première lame (13a) étant engagée sous l'extrémité avant (131b) de la deuxième lame (13b). Le recouvrement se faisant sur une longueur "l₃".Figures 21 to 24 show a variant in which there is a multiplication of longitudinal effects due to the flexing of the ski. To this end, the ski comprises two flexion blades (13a, 13b): a first front flexion blade (13a) and a second rear flexion blade (13b). The front flexion blade (13a) is fixed to the ski in front of the stop (3) by its front end (131a) by means of screws (150) and extends backwards passing freely under said stop (3). Likewise, the rear flexion blade (13b) is fixed to the ski behind the heel piece (4) by its rear end (130b) to extend forwards passing freely under said heel piece (4) as far as the central zone (2) between the two fixings (3, 4). It is noted that there is overlap of the two ends. The rear end (130a) of the first blade (13a) being engaged under the front end (131b) of the second blade (13b). The covering is done over a length "l₃".

Dans cette variante, les moyens d'amortissement sont constitués par une interface (18) constituée par une couche en matériau souple ou viscoélastique, comme précédemment, mais disposée non pas sur le ski, mais entre les deux lames dans leur zone de recouvrement. Ainsi, les extrémités arrière (130a) de la première lame (13a) et avant (131b) de la deuxième lame (13b) ne sont pas du tout liées au ski.In this variant, the damping means consist of an interface (18) constituted by a layer of flexible or viscoelastic material, as above, but disposed not on the ski, but between the two blades in their overlap zone. Thus, the rear ends (130a) of the first blade (13a) and front (131b) of the second blade (13b) are not at all linked to the ski.

Pour éviter un quelconque soulèvement des extrémités (130a et 131b) des lames de flexion (13a et 13b), on peut prévoir un organe de retenue verticale, tel qu'une vis (19) logée dans un trou oblong (190) réalisé dans l'empilage des deux extrémités (130a et 131b) et de la couche d'amortissement, comme cela est représenté aux figures 23 et 24. La retenue verticale pourrait aussi être réalisée par un étrier en forme de U renversé ou tout autre moyen.To avoid any lifting of the ends (130a and 131b) of the bending blades (13a and 13b), it is possible to provide a vertical retainer, such as a screw (19) housed in an oblong hole (190) produced in the stack of the two ends (130a and 131b) and of the damping layer, as shown in FIGS. 23 and 24. The vertical restraint could also be achieved by an inverted U-shaped bracket or any other means.

Une autre variante est représentée à la figure 25 où une deuxième couche d'amortissement (180) est collée sous l'extrémité arrière (130a) de la première lame (13a) et à la surface supérieure du ski (10).Another variant is shown in FIG. 25 where a second damping layer (180) is bonded under the rear end (130a) of the first blade (13a) and to the upper surface of the ski (10).

Dans la différentes réalisations proposées aux figures 1 à 25, le dispositif d'amortissement est disposé en dehors de la structure proprement dite du ski. Mais on ne sortirait bien entendu pas du cadre de l'invention si celui-ci était disposé dans la structure même du ski, tel que cela est représenté de façon schématique aux figures 26 et 27.In the various embodiments proposed in FIGS. 1 to 25, the damping device is arranged outside the structure proper of the ski. However, it would of course not go beyond the scope of the invention if it were arranged in the very structure of the ski, as shown schematically in FIGS. 26 and 27.

Les skis sont le plus souvent constitués d'un noyau (101) recouvert par une ou plusieurs couches de renfort supérieur (102), voire même inférieur (103). Le dessus du ski étant recouvert généralement par une couche de décors (104), tandis que le dessous comprend une couche de glissement en polyéthylène (105).The skis most often consist of a core (101) covered by one or more layers of upper reinforcement (102), or even lower (103). The top of the ski is generally covered by a layer of decorations (104), while the bottom comprises a sliding layer of polyethylene (105).

La lame de flexion, dans l'exemple représenté, est fixée sous le renfort supérieur (102) et prend place dans un logement (106) réalisé dans le noyau. Il va de soi que l'on ne sortirait pas du cadre de l'invention quelle que soit la place du dispositif d'amortissement. En effet, la lame de flexion pourrait se trouver entre le noyau (101) et le renfort inférieur (103) ou même entre le renfort supérieur (102) et la couche superficielle (104).The bending blade, in the example shown, is fixed under the upper reinforcement (102) and takes place in a housing (106) produced in the core. It goes without saying that it would not go beyond the scope of the invention whatever the place of the damping device. Indeed, the bending blade could be between the core (101) and the lower reinforcement (103) or even between the upper reinforcement (102) and the surface layer (104).

Il faut remarquer que la lame de flexion représentée et décrite précédemment a une section transversale constante, mais il pourrait en être tout autrement. Ainsi, la section de la lame, dans une coupe transversale peut être variable. En effet, la largeur peut varier, de même que l'épaisseur. La forme du profil qui, dans les réalisations représentées, est rectangulaire, pourrait être trapézoïdale et varier sur sa longueur.It should be noted that the bending blade shown and described above has a constant cross section, but it could be otherwise. Thus, the section of the blade, in a cross section can be variable. Indeed, the width can vary, as well as the thickness. The shape of the profile which, in the embodiments shown, is rectangular, could be trapezoidal and vary along its length.

La figure 28 représente une autre variante en vue latérale selon laquelle le dispositif d'amortissement est constitué par une lame (13c) fixée dans sa partie centrale (132) et dont les extrémités avant (131) et arrière (130) sont reliées élastiquement au ski (1).FIG. 28 represents another variant in side view according to which the damping device consists of a blade (13c) fixed in its central part (132) and whose front (131) and rear (130) ends are elastically connected to the ski (1).

La figure 29 montre une variante selon laquelle les lames (13c) et (13b) liées élastiquement ensemble dans la zone centrale (2) du ski sont fixées par leurs extrémités par les fixations de ski correspondantes (3 et 4).FIG. 29 shows a variant according to which the blades (13c) and (13b) linked elastically together in the central zone (2) of the ski are fixed by their ends by the corresponding ski bindings (3 and 4).

Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés à titre d'exemples, mais elle comprend aussi tous les équivalents techniques ainsi que leurs combinaisons.Of course, the invention is not limited to the embodiments described and shown by way of examples, but it also includes all the technical equivalents and their combinations.
