Description

L'invention concerne une planche de glisse creuse.The invention relates to a hollow gliding board.

Elle pourra notamment être mise en oeuvre pour la fabrication de planche de glisse sur l'eau telles qu'un surf des mers.It can in particular be implemented for the manufacture of a board for gliding on water such as a sea surf.

Les planches de glisse sont généralement des objets pleins, même lorsqu'il s'agit de flotteurs qui doivent présenter un rapport poids/volume inférieur à celui de l'eau. Pour obtenir une planche légère, on utilise généralement une technologie de fabrication composite dans laquelle la planche comporte un noyau interne qui est formé d'un matériau léger et qui est recouvert d'un matériau externe rigide donnant à la planche sa forme et sa rigidité.Gliding boards are generally solid objects, even when it comes to floats which must have a weight / volume ratio lower than that of water. To get a light board, we generally use a composite manufacturing technology in which the board has an inner core which is formed of a light material and which is covered with a rigid external material giving the board its shape and rigidity.

Pour obtenir des planches encore plus légères, il est connu d'utiliser des technologies dans lesquelles la planche obtenue est creuse.To obtain even lighter boards, it is known to use technologies in which the board obtained is hollow.

De telles planches sont en principe beaucoup plus légères que les planches traditionnelles, ce qui présente de nombreux avantages, et ce qui permet notamment d'adopter un style de conduite de la planche beaucoup plus vif. Avec ce nouveau style de conduite. l'utilisateur est conduit à demander un nouveau type de comportement dynamique de la planche.Such boards are in principle much lighter than traditional boards, which has many advantages, and which allows in particular to adopt a style of driving the board much more lively. With this new driving style. the user is leads to request a new type of dynamic behavior of the board.

Dans ce but, l'invention propose une planche de glisse creuse comportant une coque externe qui délimite au moins une cavité interne, caractérisée en ce qu'elle comporte au moins une masselotte d'inertie.To this end, the invention provides a hollow gliding board comprising a shell external which delimits at least one internal cavity, characterized in that it comprises at least a flyweight of inertia.

L'invention sera mieux comprise en se référant à la description ci-dessous et aux dessins en annexe qui lui sont rattachés, parmi lesquels :

  • les figures 1 à 5 illustrent, en vue schématique de dessus, différentes zones possibles pour le placement de la ou des masselottes en vue d'améliorer le comportement dynamique de la planche ;
  • les figures 6 à 9 illustrent, en coupe par un plan transversal, quatre modes de réalisation de l'intégration d'une ou de plusieurs masselottes dans un flotteur creux ;
  • la figure 10 est une vue agrandie d'un détail de la figure 9.
The invention will be better understood by referring to the description below and to the attached drawings which are attached to it, among which:
  • Figures 1 to 5 illustrate, in schematic top view, different possible areas for the placement of the weight or weights to improve the dynamic behavior of the board;
  • Figures 6 to 9 illustrate, in section through a transverse plane, four embodiments of the integration of one or more weights in a hollow float;
  • FIG. 10 is an enlarged view of a detail of FIG. 9.

L'invention va être plus particulièrement décrite dans le cadre d'un flotteur de surf des mers, mais elle pourra être mise en oeuvre pour d'autres planches de glisse creuses.The invention will be more particularly described in the context of a surf float for seas, but it can be used for other hollow boards.

Sur les figures 1 à 5, on a illustré de manière schématique et en vue de dessus, des flotteurs de surf 10 sur lesquels on a représenté différentes zones 24 possibles pour le positionnement de masselottes destinées à modifier l'inertie et donc le comportement dynamique de la planche sur l'eau.In Figures 1 to 5, schematically illustrated and in top view, floats surf 10 on which different zones 24 are shown possible for positioning weights intended to modify the inertia and therefore the dynamic behavior of the board on the water.

Ces zones ont été déterminées plus particulièrement pour une planche entièrement creuse, c'est-à-dire une planche 10 dont la coque délimite une cavité interne 11 qui s'étend sur presque toute la longueur et presque toute la largeur de la planche. Comme cela est montré plus en détail sur les figures 6 à 10, une telle planche 10 peut par exemple être construite en assemblant deux demi-coques 12, 14 l'une à l'autre par collage. Chaque demi-coque 12, 14 est par exemple formée d'un matériau sandwich comprenant deux peaux externes 16. chacune composée de couches de tissus de fibres imprégnées de résine thermodurcissable, les deux peaux 16 encadrant une âme 18 en matériau très léger tel que de la mousse ou un matériau en nid d'abeille. Chaque demi-coque présente une épaisseur de l'ordre du centimètre et est conformée dans un moule pour prendre la forme, respectivement, du pont 12 et de la carène 14 du flotteur. Les deux demi-coques sont assemblées par un joint de colle le long de leur plan de joint 20 qui suit le bord périphérique de la planche. De manière connue, la planche ainsi construite peut comporter au moins un raidisseur, notamment un raidisseur longitudinal 22 réalisé sous la forme d'une cloison verticale qui s'étend dans la cavité 11 le long de l'axe longitudinal central de la planche en reliant les deux demi-coques 12, 14 l'une à l'autre. Une planche 10 construite selon ce principe est par exemple décrite dans le document US-3.514.798.These zones have been determined more particularly for an entirely hollow board, that is to say a board 10 whose shell delimits an internal cavity 11 which extends over almost the entire length and almost the entire width of the board. As shown more in detail in FIGS. 6 to 10, such a board 10 can for example be constructed in assembling two half-shells 12, 14 to each other by gluing. Each half-shell 12, 14 is for example formed from a sandwich material comprising two outer skins 16. each composed of layers of fiber fabrics impregnated with thermosetting resin, both skins 16 framing a core 18 of very light material such as foam or a material Honeycomb. Each half-shell has a thickness of the order of a centimeter and is shaped in a mold to take the shape, respectively, of the deck 12 and the hull 14 of the float. The two half-shells are assembled by a glue joint along their plane joint 20 which follows the peripheral edge of the board. In known manner, the board as well constructed may include at least one stiffener, in particular a longitudinal stiffener 22 produced in the form of a vertical partition which extends into the cavity 11 along the axis longitudinal center of the board by connecting the two half-shells 12, 14 to each other. A board 10 constructed according to this principle is for example described in document US-3,514,798.

Par rapport à une construction traditionnelle de planche pleine comportant un noyau de mousse entouré d'une couche externe de tissus de fibres imprégnées de résine, une construction creuse permet de passer d'un poids d'environ 3kg à un poids d'environ 2 kg pour une planche de surf de même forme et présentant des caractéristiques mécaniques équivalentes ou supérieures. Ce gain de poids, pouvant être supérieur à 30 %, permet de changer de manière radicale le comportement de la planche sur l'eau, et se traduit notamment par une plus grande vitesse et par une plus grande vivacité de la planche. Cependant, dans certaines conditions de vagues, et pour la réalisation de certaines figures, il est apparu qu'une planche creuse munie de masselottes judicieusement positionnées pouvait donner d'encore meilleurs résultats.Compared to a traditional solid board construction with a core of foam surrounded by an outer layer of fiber fabrics impregnated with resin, a hollow construction allows to go from a weight of about 3kg to a weight of about 2 kg for a surfboard of the same shape and having mechanical characteristics equivalent or higher. This weight gain, which can be greater than 30%, allows radically change the behavior of the board on water, and is reflected in particular by greater speed and greater liveliness of the board. However, in certain wave conditions, and for the realization of certain figures, it appeared that a hollow board fitted with carefully positioned flyweights could still give best results.

Sur la figure 1, on a illustré la possibilité de disposer deux masselottes d'inertie 24 sur les côtés flotteur, longitudinalement au niveau du point milieu du flotteur ou légèrement en avant de celui-ci. Avec cette configuration, on augmente de manière non négligeable le moment d'inertie en rotation autour de l'axe longitudinal de la planche. Un résultat optimal est obtenu en utilisant deux masselottes ayant chacune un poids inférieur à 100 grammes, de préférence de l'ordre de 50 grammes. On voit donc que, au global, on conserve un poids largement inférieur à celui d'une planche de surf traditionnelle. Le léger ajout de poids ne pénalise pas les qualités de vitesse et de maniabilité de la planche creuse, mais le surcroít d'inertie en roulis permet de mieux contrôler la prise de carres, donc de mieux contrôler la planche en virages.In Figure 1, there is illustrated the possibility of having two flywheels 24 on the float sides, longitudinally at the midpoint of the float or slightly forward of it. With this configuration, the moment is significantly increased of inertia in rotation around the longitudinal axis of the board. Optimal results are obtained using two weights each weighing less than 100 grams, preferably of the order of 50 grams. So we see that, overall, we keep a weight largely lower than that of a traditional surfboard. The slight addition of weight does not penalize the qualities of speed and maneuverability of the hollow board, but the additional inertia in roll allows better control of the edge grip, therefore better control of the board when cornering.

Sur la figure 2, on a illustré la possibilité de disposer une masselotte 24 dans une zone située près de l'extrémité arrière de la planche, cette zone pouvant aller jusqu'à la zone d'appui du pied arrière du surfeur. En disposant une masselotte dans cette zone, la planche gagne en stabilité mais aura tendance à perdre en vitesseIn FIG. 2, the possibility of having a counterweight 24 in an area has been illustrated. located near the rear end of the board, this area can go up to the support area of the surfer's back foot. By placing a flyweight in this area, the board gains stability but will tend to lose speed

Sur la figure 3, on a illustré la possibilité de disposer une masselotte 24 dans la zone qui correspond à la zone d'appui du pied avant du surfeur. Cette zone correspond sensiblement à la zone du centre de gravité de la planche. Ici, la masselotte sera d'un poids inférieur à 200 grammes, de préférence compris entre 100 et 150 grammes. Avec, cette position de la masselotte, la planche est légèrement moins vive qu'une planche sans masselotte, ce qui pourra faciliter le contrôle de la planche dans certaines conditions. De plus, le surcroít de poids, et donc d'inertie, permet à la planche de conserver plus facilement de la vitesse en fin de manoeuvre.In FIG. 3, the possibility of having a counterweight 24 has been illustrated in the area which corresponds to the support area of the front foot of the surfer. This zone corresponds substantially to the area of the center of gravity of the board. Here, the weight will be of a weight less than 200 grams, preferably between 100 and 150 grams. With, this position of the counterweight, the board is slightly less lively than a board without counterweight, which may facilitate the control of the board under certain conditions. In addition, the additional weight, and therefore of inertia, allows the board to keep speed more easily at the end maneuver.

Une autre possibilité, représentée à la figure 4, consiste à disposer une masselotte d'inertie 24 longiligne répartie sur une partie au moins de la longueur de chacun des bords de la planche. A l'extrême, la masselotte 24 pourra ainsi s'étendre sur toute la périphérie de la planche. Bien entendu, la masse globale des masselottes ainsi réparties doit rester relativement faible, et on aura donc tout avantage à utiliser comme masselotte un cordon de mousse. Avantageusement, on pourra prévoir que l'assemblage des deux demi-coque 12, 14 soit réalisé à l'aide d'une résine adhésive moussante, et que la masselotte périphérique 24 soit réalisée à l'aide du même matériau, éventuellement au cours de la même opération en faisant en sorte que le joint de collage "déborde" vers l'intérieur de la cavité interne 11 de la planche.Another possibility, shown in Figure 4, is to have a flywheel 24 slender spread over at least part of the length of each of the edges of the board. In the extreme, the counterweight 24 can thus extend over the entire periphery of the board. Of course, the overall mass of the weights thus distributed must remain relatively low, and it will therefore be advantageous to use a foam bead as a counterweight. Advantageously, provision may be made for the assembly of the two half-shells 12, 14 to be carried out using a foaming adhesive resin, and that the peripheral counterweight 24 is produced at using the same material, possibly during the same operation making sure that the bonding joint "projects" towards the inside of the internal cavity 11 of the board.

A la figure 5, on voit qu'il est aussi possible de disposer la masselotte 24 dans une zone avant de la planche. Cette possibilité pourra notamment être exploitée pour des planches relativement longues destinées à la pratique du surf dans des vagues hautes.In FIG. 5, it can be seen that it is also possible to arrange the counterweight 24 in an area front of the board. This possibility could in particular be exploited for boards relatively long intended for the practice of surfing in high waves.

Bien entendu, en fonction des résultats recherchés, on pourra être amené à déterminer d'autres positions préférentielles pour la ou les masselottes. On pourra aussi combiner plusieurs positions de masselottes, notamment plusieurs des positions qui sont décrites plus haut.Of course, depending on the results sought, we may have to determine other preferential positions for the flyweight (s). We can also combine several weights positions, in particular several of the positions which are described more high.

Sur les figures 6 à 10, on a illustré divers modes de constructions de ces masselottes.In Figures 6 to 10, various modes of construction of these weights have been illustrated.

Comme illustré à la figure 6, la masselotte 24 peut être constituée d'un bloc de matière fixé sur une des faces de la cavité interne 11. La matière utilisée pourra être une matière dense, par exemple un bloc de résine, auquel cas la masselotte 24 sera de petite taille, et l'ajout de masse sera alors parfaitement concentré, tant dans son positionnement horizontal dans le plan de la planche que selon la direction verticale dans le sens de l'épaisseur de la planche. A l'inverse, la masselotte pourra être constituée par un matériau peu dense tel qu'un bloc de mousse, auquel cas la masselotte sera de plus grande dimension. Dans l'exemple de la figure 6, la masselotte ne fait pas la liaison en hauteur entre le pont et la carène, et il est donc possible de la fixer soit du côté du pont 12, soit du côté de la carène 14 (comme illustré). Bien entendu, le choix de tel ou tel positionnement aura des incidences sur le comportement de la planche.As illustrated in FIG. 6, the counterweight 24 can consist of a fixed block of material on one of the faces of the internal cavity 11. The material used may be a dense material, for example a block of resin, in which case the counterweight 24 will be small, and the addition of mass will then be perfectly concentrated, both in its horizontal positioning in the plane of the board only in the vertical direction in the thickness direction of the board. Conversely, the counterweight may be made of a sparse material such as a block of foam, to which in this case the weight will be larger. In the example in Figure 6, the flyweight does not make the connection in height between the deck and the hull, and it is therefore possible to fix it either on the side of the deck 12, or on the side of the hull 14 (as illustrated). Of course, the choice of such or such positioning will affect the behavior of the board.

Dans l'exemple de la figure 7, la masselotte 24 s'étend au contraire sur toute la hauteur de cavité interne et elle peut former, en plus de son rôle de modification de l'inertie de la planche, un renfort entre le pont 12 et la carène 14 pour limiter l'apparition d'enfoncements. Dans ce cas, compte tenu du poids limité de la masselotte, le matériau utilisé sera de préférence une mousse ou un matériau en nid d'abeille. Un tel mode de réalisation sera par exemple utilisé pour les planches les moins épaisses, ou lorsque la masselotte 24 est disposée dans une zone de faible épaisseur de la planche, comme par exemple dans le cas des modes de réalisation des figures 2 et 5. In the example of FIG. 7, the counterweight 24, on the contrary, extends over the entire height of internal cavity and it can form, in addition to its role of modifying the inertia of the board, a reinforcement between the deck 12 and the hull 14 to limit the appearance of sinking. In this case, given the limited weight of the counterweight, the material used will preferably be a foam or honeycomb material. Such an embodiment will for example be used for thinner boards, or when the counterweight 24 is placed in an area thin board, as for example in the case of embodiments of Figures 2 and 5.

Dans l'exemple de la figure 8, la planche est du type comportant un raidisseur longitudinal interne 22, et les masselottes 24 sont disposées au voisinage des flotteurs, comme dans les exemples de réalisation des figures 1 et 4. Ici. la masselotte peut par exemple être réalisée avec un bloc de mousse rigide taillé à forme adéquate, ou il peut s'agir d'un bloc de mousse que l'on laisse s'expanser à l'intérieur de la planche au moment de l'assemblage des deux demi-coques 12, 14.In the example of FIG. 8, the board is of the type comprising a longitudinal stiffener internal 22, and the flyweights 24 are arranged in the vicinity of the floats, as in the exemplary embodiments of FIGS. 1 and 4. Here. the counterweight can for example be carried out with a rigid foam block cut to an appropriate shape, or it can be a foam block which is allowed to expand inside the board when the two are assembled half-shells 12, 14.

Dans l'exemple de la figure 9, dans laquelle on peut voir que la planche comporte trois raidisseurs longitudinaux 22, la masselotte 24 est directement intégrée dans la structure de l'une des demi-coque. En l'occurrence, comme le montre le détail de la figure 10, la demi-coque présente une structure sandwich et la masselotte 24 est intégrée dans l'âme 18, entre les deux peaux 16 du sandwich. La masselotte 24 peut par exemple être formée d'une feuille de matériau dense, éventuellement une feuille métallique. Dans l'exemple illustré, la masselotte est située du côté intérieur de l'âme qui est le plus proche de la cavité 11. On peut prévoir aussi que la masselotte soit agencée du côté extérieur de l'âme, ou encore que la masselotte s'étende sur toute l'épaisseur entre les deux peaux 16. Bien entendu, une telle construction peut être prévue aussi bien sur la carène 14 que sur le pont 12, et la masselotte 24 peut être agencée transversalement au centre ou au contraire sur les côtés de la planche.In the example of Figure 9, in which we can see that the board has three longitudinal stiffeners 22, the counterweight 24 is directly integrated into the structure of one of the half-hulls. In this case, as shown in detail in Figure 10, the half-shell has a sandwich structure and the flyweight 24 is integrated into the core 18, between the two skins 16 of the sandwich. The counterweight 24 can for example be formed from a sheet of dense material, possibly a metallic foil. In the example illustrated, the flyweight is located on the inner side of the core which is closest to the cavity 11. We can provide also that the counterweight is arranged on the outer side of the core, or that the counterweight extends over the entire thickness between the two skins 16. Of course, such a construction can be provided both on the hull 14 and on the deck 12, and the counterweight 24 can be arranged transversely in the center or on the contrary on the sides of the board.

Bien entendu, d'autres modes de réalisation sont possibles pour la construction de la ou des masselottes.Of course, other embodiments are possible for the construction of the one or more weights.

Dans tous les cas, la masselotte selon l'invention ne devra pas être confondue avec un renfort et un raidisseur classique, desquelles elle se démarque, outre par sa fonction, par son positionnement et par son poids qui en règle générale ne dépassera pas 200 grammes. La planche de glisse ainsi proposée est donc originale, notamment en ce sens que l'invention permet de modifier de manière sensible le comportement d'une planche creuse, en conservant une très grande partie des qualités intrinsèques dues à la légèreté de ces planches creuses.In all cases, the counterweight according to the invention should not be confused with a reinforcement and a classic stiffener, from which it stands out, in addition to its function, by its positioning and its weight which as a rule will not exceed 200 grams. The gliding board thus proposed is therefore original, in particular in that the invention allows you to significantly modify the behavior of a hollow board, keeping a very large part of the intrinsic qualities due to the lightness of these hollow planks.
