Description

La présente invention se rapporte à une planche de glisse sur neige telle qu'un ski, un monoski, un surf, ou autre. Elle concerne plus particulièrement un perfectionnement relatif à une planche de glisse dont la structure est du type dite"sandwich".The present invention relates to a snow board on snow such as a ski, a monoski, a surf, or other. It relates more particularly to an improvement relating to a gliding board whose structure is of the type called "sandwich".

La pratique des sports de glisse fait de plus en plus d'adeptes et a beaucoup évolué ces dernières années avec des pratiquants de plus en plus exigeants sur la qualité des produits. Tel est, par exemple, le cas des sports de glisse sur neige.The practice of boardsports is becoming more and more followers and has evolved in recent years with more and more demanding practitioners on the quality of products. This is, for example, the case of snow sports.

On connaît déjà de très nombreux modèles de planches de glisse, et notamment de skis, qui sont constitués par une poutre de forme allongée d'épaisseur variable, dont l'extrémité avant est relevée pour constituer la spatule, tandis que la surface inférieure comprend une semelle de glissement bordée par des carres métalliques.Numerous models of gliding boards, and especially skis, which are constituted by an elongated beam of variable thickness, the front end of which is raised to form the spatula, while the lower surface comprises a slip sole bordered by metal edges.

Malgré tous les efforts développés par les constructeurs pour satisfaire la clientèle, il n'existe pas, à ce jour, de ski associant parfaitement le confort d'utilisation à des caractéristiques satisfaisantes de comportement dans les trajectoires, quel que soit le type de terrain, et quel que soit l'utilisateur.Despite all the efforts made by the manufacturers to satisfy the customers, there is not, to date, ski combining perfectly the comfort of use with satisfactory characteristics of behavior in the trajectories, whatever the type of ground, and whoever the user is.

Certaines solutions ont été proposées, comme par exemple par les constructions divulguées par les brevets américains US publiés sous le numéro 2006/0091645 , le brevet français 1 294 003 , le brevet français FR 2 798 297 , le brevet japonais 55112577 , le brevet français FR 2 683 734 , 2 670 392 et 2 675 391 . Mais toutes ces propositions s'avèrent ne pas être parfaites, et la présente invention veut donc remédier à cela en proposant une planche de glisse n'ayant pas les mêmes caractéristiques de raideur sur ses bordures latérales afin de localiser des zones d'accrochage sur la neige et améliorer localement cet accrochage.Some solutions have been proposed, as for example by the constructions disclosed by US patents US published under number 2006/0091645 , the French patent 1 294 003 , the French patent FR 2 798 297 , the Japanese patent 55112577 , the French patent FR 2,683,734 , 2,670,392 and 2,675,391 . But all these proposals turn out not to be perfect, and the present invention seeks to remedy this by proposing a gliding board not having the same characteristics of stiffness on its side edges to locate snap areas on the snow and locally improve this attachment.

On connaît aussi le ski divulgué par la demande internationale de brevet WO 97/06864 qui divulgue une ski ayant la forme d'une poutre allongée d'épaisseur variable, comportant une zone centrale dite de patin prolongée vers l'avant par une zone avant relevée à son extrémité pour constituer une spatule, et vers l'arrière par une zone arrière terminée par un talon, ladite poutre comprenant un noyau longitudinal central constitue par une poutre s'étendant longitudinalement, au moins une couche de renfort, une couche supérieure de protection et de décor une couche de glissement réalisée par une feuille d'un matériau à faible coefficient de frottement bordée par deux carres, tandis qu'à chacune des faces latérales du noyau est solidarisé un chant, ce chant étant prolongé latéralement par un chant externe grâce à un passage dans la couche de renfort lors de la fabrication du ski. Selon la construction antérieure le chant externe n'est pas intimement lié au chant interne qui lui est en contact avec le noyau. Cette structure bien que perfectionnée ne permet pas de réaliser un ski qui donne satisfaction dans tout les types de neige et ne permet pas notamment de localiser des zones d'accrochage.The ski disclosed by the international patent application is also known WO 97/06864 which discloses a ski having the shape of an elongate beam of variable thickness, comprising a central zone called pad extended forwards by a front zone raised at its end to form a spatula, and backwards by a zone rear end with a bead, said beam comprising a central longitudinal core is constituted by a beam extending longitudinally, at least one reinforcing layer, a top layer of protection and decoration a sliding layer made by a sheet of a material to low coefficient of friction bordered by two edges, while each of the lateral faces of the core is secured a song, this song being extended laterally by an external edge through a passage in the reinforcing layer during the manufacture of the ski. According to the previous construction, the outer song is not intimately related to the inner song which is in contact with the nucleus. This structure, although perfected, does not make it possible to make a ski which is satisfactory in all types of snow and does not make it possible, in particular, to locate snap zones.

Ainsi la planche de glisse sur neige selon l'invention, ayant la forme d'une poutre allongée d'épaisseur variable, comportant une zone centrale dite de patin prolongée vers l'avant par une zone avant relevée à son extrémité pour constituer une spatule, et vers l'arrière par une zone arrière terminée par un talon, ladite poutre comprenant

  • un noyau longitudinal central constitué par une poutre s'étendant longitudinalement,
  • au moins une couche de renfort
  • une couche supérieure de protection et de décor
  • une couche de glissement réalisée par une feuille d'un matériau à faible coefficient de frottement bordée par deux carres,
tandis qu'à chacune des faces latérales du noyau est solidarisé un chant respectivement
est caractérisée en ce que l'un au moins des chants est constitué au moins sur une partie de la longueur de la planche, de deux éléments de chant intimement liés, s'étendant longitudinalement, à savoir un élément interne de chant dont la face latérale interne est solidarisée à la face latérale du noyau et un élément externe de chant, tandis que la largeur d'au moins un des chants varie longitudinalement, tandis que les deux éléments de chant sont solidarisés ensemble par la coopération de formes entre les faces latérales adjacentes, à savoir entre la face latérale interne de l'élément externe et la face latérale externe de l'élément interne.Thus the snow sliding board according to the invention, having the shape of an elongated beam of variable thickness, comprising a central zone called pad extended forwards by a front zone raised at its end to form a spatula, and rearwards by a rear area terminated by a heel, said beam comprising
  • a central longitudinal core constituted by a longitudinally extending beam,
  • at least one reinforcing layer
  • a top layer of protection and decor
  • a sliding layer formed by a sheet of a low friction material bordered by two edges,
while at each of the lateral faces of the core is secured a respective singing
is characterized in that at least one of the songs is made up of at least a part of the length of the board, two intimately linked, longitudinally extending edge members, namely an internal vocal element whose side face internal is secured to the lateral face of the core and an outer edge element, while the width of at least one of the songs varies longitudinally, while the two edge elements are joined together by the cooperation of shapes between the adjacent lateral faces, namely between the internal lateral face of the external element and the external lateral face of the inner element.

  • une couche de glissement (10) réalisée par une feuille d'un matériau à faible coefficient de frottement bordée par deux carres métalliques (11a, 11b), qui définissent une courbure longitudinale que l'on appelle la ligne de cotes (LC).
tandis qu'à chacune des faces latérales (12a, 12b) du noyau (7) est solidarisé directement ou indirectement un chant respectivement (13a, 13b) constitué par au moins un profil longitudinal, à savoir un chant gauche (13a) et un chant droit (13b), le noyau pouvant être recouvert d'une couche de renfort pour constituer une boite de torsion.The gliding board of the invention is for example of the type of construction called "sandwich". Thus, and as is clear from the figure 2 , the body of the gliding board includes
  • a central longitudinal core (7) consisting of a longitudinally extending beam,
  • at least one reinforcing layer (8a, 8b, 8c)
  • a top layer of protection and decoration (9)
  • a sliding layer (10) formed by a sheet of a low friction material bordered by two metal edges (11a, 11b), which define a longitudinal curvature known as the dimension line (LC).
while at each of the lateral faces (12a, 12b) of the core (7) is joined directly or indirectly a respective edge (13a, 13b) formed by at least one longitudinal profile, namely a singing left (13a) and a right edge (13b), the core may be covered with a reinforcing layer to form a torsion box.

Selon les réalisations illustrées plus particulièrement aux figures 4, 5, 7 et 8, et données à titre d'exemples non limitatifs, le corps de la planche de glisse, comprend une couche de renfort supérieur (8a), et deux couches de renfort inférieur (8b, 8c).According to the achievements illustrated in particular Figures 4, 5 , 7 and 8 and given as non-limiting examples, the body of the gliding board comprises an upper reinforcing layer (8a), and two lower reinforcing layers (8b, 8c).

De façon connue, les couches de renforts sont en matériau composite tels que de la fibre de verre, de carbone, d'aramide, de céramique ou autre imprégné d'une résine thermoplastique ou des résines thermodurcissables, voir en aluminium.In known manner, the reinforcing layers are of composite material such as fiberglass, carbon, aramid, ceramic or other impregnated with a thermoplastic resin or thermosetting resins, see aluminum.

La couche de protection et de décor (9) est par exemple en matière thermoplastique telle qu'en acrylonitrile butadiène styrène (ABS) ou en polyamide ou en polycarbonate ou autreThe protective and decorative layer (9) is for example made of thermoplastic material such as acrylonitrile butadiene styrene (ABS) or polyamide or polycarbonate or other

La couche de glissement (10) est par exemple en polyéthylène.The slip layer (10) is for example polyethylene.

Les chants (13a, 13b) sont en matière plastique comme par exemple de type ABS avantageusement chargée, voir en matière phénolique compriméeThe edges (13a, 13b) are made of plastic such as, for example, of the ABS type that is advantageously loaded, see in compressed phenolic material

Le noyau (7) est en bois ou en mousse synthétique tel qu'en polyuréthane expansé.The core (7) is made of wood or synthetic foam such as expanded polyurethane.

Selon les réalisations telles qu'illustrées, chacun des chants latéraux (13a, 13b) est un profilé longitudinal dont la hauteur (H) est supérieure à sa largeur (e). On notera que la hauteur (H) est sensiblement égale à l'épaisseur du noyau. Ainsi, la hauteur (H) de chacun des chants est variable pour évoluer avec la valeur de l'épaisseur du noyau.According to the embodiments as illustrated, each of the side edges (13a, 13b) is a longitudinal profile whose height (H) is greater than its width (e). Note that the height (H) is substantially equal to the thickness of the core. Thus, the height (H) of each song is variable to evolve with the value of the thickness of the core.

Selon l'invention la largeur (e) d'au moins l'un des chants (13a, 13b), est telle que sur la longueur, cette largeur évolue. En d'autres termes la largeur (e) du chant varie longitudinalement, pour présenter au moins une zone de largeur plus importante que celle que l'on trouve en d'autres endroits sur la longueur. Bien entendu, chacun des chants (13a, 13b) peut être concerné par la variation de largeur.According to the invention the width (e) of at least one of the songs (13a, 13b) is such that over the length, this width evolves. In other words, the width (e) of the edge varies longitudinally to present at least one zone of greater width than that which is found in other places along the length. Of course, each of the songs (13a, 13b) may be concerned with the variation of width.

Selon les modes de réalisation, représentées par les figures 2 à 12, au moins l'un des chants (13a, 13b) est constitué de deux éléments de chant (13'a, 13"a - 13'b, 13"b) intimement liés, s'étendant longitudinalement, à savoir un élément interne de chant (13"a, 13"b) dont la face latérale interne (14a, 14b) est solidarisée à la face latérale (12a, 12b) du noyau (7) et un élément externe de chant (13'a, 13'b). Notons que les deux éléments de chant sont solidarisés ensemble par la coopération de formes entres les faces latérales adjacentes (18'a,18"a- 18'b, 18"b), à savoir entre la face latérale interne (18'a, 18'b) de l'élément externe (13'a, 13'b) et la face latérale externe (18" a, 18"b) de l'élément interne (13"a, 13"b).According to the embodiments, represented by the Figures 2 to 12 at least one of the songs (13a, 13b) consists of two intimately connected singing elements (13'a, 13 "a-13'b, 13" b) extending longitudinally, namely an internal element of edge (13 "a, 13" b) whose internal lateral face (14a, 14b) is secured to the lateral face (12a, 12b) of the core (7) and an external edge element (13'a, 13 ') b). Note that the two edge elements are secured together by the cooperation of shapes between adjacent side faces (18'a, 18 "a-18'b, 18" b), namely between the inner side face (18'a, 18'b) of the outer member (13'a, 13'b) and the outer side face (18 "a, 18" b) of the inner member (13 "a, 13" b).

Selon la variante de réalisation illustrée à la figure 2, les éléments externes de chant (13'a,13'b), ne présentent pas d'ondulation, et suivent le profil de la ligne de cote tout en ayant une largeur (e) constante, et l'élément interne de chant (13"a, 13"b) présente une ondulation notamment vers le plan (P). Ainsi, le chant (13a, 13b) comprend deux zones de moindre largeur (15a, 15'a - 15b, 15'b), séparées par une zone en saillie (16a, 16b) dite saillie centrale s'étendant vers le plan (P), tandis que la zone avant de moindre largeur (15a, 15b) est limitée vers l'avant (AV) par une saillie avant (16'a, 16'b), tandis que la zone arrière de moindre largeur (15'a,15'b) est limitée longitudinalement par la saillie centrale (16a, 16b) et vers l'arrière (AR), par une saillie arrière (16"a, 16"'b). On a compris que la succession d'une saillie (16'a, 16'b), d'un creux (15a, 15b) d'une saillie (16a, 16b) et d'un creux (15'a, 15'b) suivi d'une saillie (16"a, 16"b) forme une ondulation de la face interne (14a, 14b) du chant (13a, 13b). Cette ondulation est réalisée en particulier sur une planche de surf pour améliorer son accrochage sur la neige. Ainsi, grâce à la construction proposée la planche de glisse comporte des zones où l'accrochage est maximum dans les zones ou le chant et notamment ses éléments internes de chant sont en saillie et de plus grande largeur.According to the embodiment variant illustrated in figure 2 the outer edge elements (13'a, 13'b) do not show any undulation, and follow the profile of the dimension line while having a constant width (e), and the inner edge element ( 13 "a, 13" b) has a corrugation in particular towards the plane (P). Thus, the edge (13a, 13b) comprises two zones of smaller width (15a, 15'a-15b, 15'b), separated by a protruding zone (16a, 16b) said central projection extending towards the plane ( P), while the front zone of smaller width (15a, 15b) is limited forwardly (AV) by a front projection (16'a, 16'b), while the rear zone of smaller width (15 ') a, 15'b) is limited longitudinally by the central projection (16a, 16b) and rearwardly (AR), by a rear projection (16 "a, 16"'b). We have understood that the succession of a projection (16'a, 16'b), a recess (15a, 15b) of a projection (16a, 16b) and a recess (15'a, 15'b) followed by a protrusion (16 "a, 16" b) forms a corrugation of the inner face (14a, 14b) of the edge (13a, 13b). This wave is made especially on a surfboard to improve its grip on the snow. Thus, thanks to the proposed construction the gliding board has areas where the attachment is maximum in the areas where the edge and in particular its internal singing elements are projecting and wider.

Selon les modes de réalisations décrits précédemment, c'est la face latérale interne (14a, 14b) du chant (13a, 13b), en contact et solidarisé avec la face latérale externe (12a, 12b) du noyau (7) qui comprend la ou les zones en saillie (16'a, 16a, 16"a - 16'b, 16b, 16"b), mais il pourrait en être autrement. Car en effet, c'est la face latérale externe (17a, 17b) du chant (13a, 13b) qui pourrait comprendre la ou les zones en saillie, voir l'ondulation.According to the embodiments described above, it is the internal lateral face (14a, 14b) of the edge (13a, 13b), in contact and secured to the external lateral face (12a, 12b) of the core (7) which comprises the or the protruding areas (16'a, 16a, 16 "a - 16'b, 16b, 16" b), but it could be otherwise. Indeed, it is the external lateral face (17a, 17b) of the song (13a, 13b) which could include the projecting zone or zones, see the undulation.

Selon la variante illustrée à la figure 3, la face latérale interne (18'a, 18'b) de l'élément externe de chant (13'a, 13'b) présente une ondulation en coopération de forme avec une ondulation de forme et de dimensions correspondantes, réalisée sur la face latérale externe (18"a, 18"b) de l'élément interne de chant (13"a, 13"b).According to the variant illustrated in figure 3 the inner side face (18'a, 18'b) of the outer edge element (13'a, 13'b) has a shape-compliant corrugation with a corrugation of corresponding shape and size, formed on the external side face (18 "a, 18" b) of the inner edge element (13 "a, 13" b).

Selon les modes de réalisation décrits précédemment, les faces latérales externes (17a, 17b) s'étendent verticalement pour faire sensiblement un angle droit (A) avec la surface de glisse (S). Les génératrices engendrant les surfaces latérales externes (17a, 17b) des chants (13a, 13b) sont sensiblement perpendiculaires par rapport à la surface de glisse (S) et suivent longitudinalement les lignes de cotes (LC).According to the embodiments described above, the outer lateral faces (17a, 17b) extend vertically to make substantially a right angle (A) with the sliding surface (S). Generators generating the external lateral surfaces (17a, 17b) of the edges (13a, 13b) are substantially perpendicular with respect to the sliding surface (S) and follow longitudinally the dimension lines (LC).

Ainsi les figures 4 et 5 sont des vues en coupe transversale selon A-A de la figure 2 et de la figure 3 pour l'illustration de la figure 4 et selon B-B de la figure 3 pour l'illustration de la figure 5.So the Figures 4 and 5 are cross-sectional views along AA of the figure 2 and some figure 3 for the illustration of the figure 4 and according to BB of the figure 3 for the illustration of the figure 5 .

La figure 6 est une vue schématique de dessus, d'une variante selon laquelle le chant (13a, 13b) comprend comme précédemment, deux éléments de chant (13'a, 13'b - 13"a, 13"b) et selon laquelle la face latérale externe (17a, 17b) est inclinée. Ainsi au niveau des carres, la face latérale externe présente la courbure inférieure (C1) tandis qu'en partie haute elle présente la courbure supérieure (C2), ces deux courbures suivant la ligne de cote (LC). Cette disposition peut d'ailleurs être obtenue par usinage des chants. Ce qui aura pour effet si les éléments de chants sont de couleur différente de voir à certains endroits apparaître la couleur de l'élément interne de chant, créant ainsi des effets de couleurs.The figure 6 is a schematic view from above, of a variant according to which the edge (13a, 13b) comprises, as before, two edge elements (13'a, 13'b-13 "a, 13" b) and according to which the face external side (17a, 17b) is inclined. Thus at the edges, the outer side face has the lower curvature (C1) while in the upper part it has the upper curvature (C2), these two curvatures along the dimension line (LC). This arrangement can also be obtained by machining the songs. Which will have the effect if the elements of songs are of different color to see in some places appear the color of the inner element of song, thus creating effects of colors.

Selon une autre réalisation illustrée à la figure 6a, et aux figures 7 et 8, l'angle d'inclinaison (A) est variable pour avoir une valeur importante dans la zone du patin (2) et diminuer progressivement vers les extrémités. La figure 7 est une vue en coupe selon C-C de la figure 6a, tandis que la figure 8 est une vue en coupe selon D-D de la figure 6a.According to another embodiment illustrated in figure 6a , and Figures 7 and 8 , the angle of inclination (A) is variable to have a significant value in the area of the pad (2) and gradually decrease towards the ends. The figure 7 is a sectional view according to CC of the figure 6a while the figure 8 is a sectional view according to DD of the figure 6a .

Notons que si la génératrice est suffisamment inclinée, sur les faces latérales de la planche de glisse apparaitront les deux éléments constituant les chants.Note that if the generator is sufficiently inclined, on the side faces of the gliding board will appear the two elements constituting the songs.

Les figures 9 à 12 sont des demi-vues schématiques de dessus partielles similaires à la figure 6, illustrant quatre variantes de réalisation.The Figures 9 to 12 are partial schematic half-views of partial tops similar to the figure 6 illustrating four alternative embodiments.

Selon la variante illustrée à la figure 9 le chant est tel que dans la zone du patin (2) le chant (13a, 13b) est constitué seulement d'un élément interne de chant (13"a, 13"b) tandis que dans les zones avant (3) et arrière (1) de la planche de glisse, le chant est constitué de deux éléments de chant (13'a, 13"a - 13'b, 13"b) intimement liés, s'étendant longitudinalement, à savoir un élément interne de chant (13"a, 13"b) dont la face latérale interne (14a, 14b) est solidarisée à la face latérale (12a, 12b) du noyau (7) et un élément externe de chant (13'a, 13'b). Notons que les deux éléments de chant sont solidarisés ensemble par la coopération de formes entres les faces latérales adjacentes (18'a,18"a- 18'b, 18"b), à savoir entre la face latérale interne (18'a, 18'b) de l'élément externe (13'a, 13'b) et la face latérale externe (18"a, 18"b) de l'élément interne (13"a, 13"b). On notera aussi que selon ce mode de réalisation la largeur du chant (e) est variable. On notera que dans la zone du patin (2) le chant (13a, 13b) n'est constitué que de l'élément interne de chant (13"a, 13"b), tandis que dans les zones avant (3) et arrière (5) le chant comprend les deux éléments de chant. La figure 4 est une vue selon la demi coupe transversale A-A de la figure 9. La figure 5 est une vue selon la demi coupe transversale B-B de la figure 9.According to the variant illustrated in figure 9 the edge is such that in the area of the pad (2) the edge (13a, 13b) consists only of an inner edge element (13 "a, 13" b) while in the front (3) and rear zones (1) of the gliding board, the song consists of two intimately linked singing elements (13'a, 13 "a-13'b, 13" b), extending longitudinally, namely an internal singing element (13 "a, 13" b) whose inner lateral face (14a, 14b) is secured to the lateral face (12a, 12b) of the core (7) and an external edge element (13'a, 13'b) . Note that the two edge elements are secured together by the cooperation of shapes between adjacent side faces (18'a, 18 "a-18'b, 18" b), namely between the inner side face (18'a, 18'b) of the outer member (13'a, 13'b) and the outer side face (18 "a, 18" b) of the inner member (13 "a, 13" b). Note also that according to this embodiment the width of the song (e) is variable. Note that in the area of the shoe (2) the edge (13a, 13b) consists only of the inner edge element (13 "a, 13" b), while in the front zones (3) and back (5) the song includes both singing elements. The figure 4 is a view along the half-cross section AA of the figure 9 . The figure 5 is a view along the half-cross section BB of the figure 9 .

Selon la variante illustrée à la figure 10 le chant (13a, 13b) est constitué de deux éléments de chant (13'a, 13"a - 13'b, 13"b) intimement liés, s'étendant longitudinalement, à savoir un élément interne de chant (13"a, 13"b) dont la face latérale interne (14a, 14b) est solidarisée à la face latérale (12a, 12b) du noyau (7) et un élément externe de chant (13'a, 13'b). Notons que comme précédemment, les deux éléments de chant sont solidarisés ensemble par la coopération de formes entres les faces latérales adjacentes (18'a,18"a- 18'b, 18"b), à savoir entre la face latérale interne (18'a, 18'b) de l'élément externe (13'a, 13'b) et la face latérale externe (18"a, 18"b) de l'élément interne (13"a, 13"b). On notera aussi que selon ce mode de réalisation la largeur de l'élément interne de chant (13"a, 13"b) du chant est constante tandis que la largeur de l'élément externe (13'a, 13'b) est variable pour augmenter depuis la zone du patin (2) vers les extrémités. La figure 5 est une vue selon la demi coupe transversale B-B de la figure 10. On a compris que le chant (13) comprenait deux éléments de chant (13a,13'a) dans les zones avant (3) et arrière (5) dont la largeur varie sur leur longueur.According to the variant illustrated in figure 10 the edge (13a, 13b) consists of two intimately connected singing elements (13'a, 13 "a-13'b, 13" b) extending longitudinally, namely an internal vocal element (13 "a , 13 "b) whose inner lateral face (14a, 14b) is secured to the lateral face (12a, 12b) of the core (7) and an outer edge element (13'a, 13'b). Note that as before, the two edge elements are secured together by the cooperation of shapes between the adjacent side faces (18'a, 18 "a-18'b, 18" b), namely between the internal lateral face (18 'a, 18'b) of the outer member (13'a, 13'b) and the outer side face (18 "a, 18" b) of the inner member (13 "a, 13" b). It will also be noted that according to this embodiment the width of the internal singing element (13 "a, 13" b) of the edge is constant while the width of the outer element (13'a, 13'b) is variable to increase from the pad area (2) to the ends. The figure 5 is a view along the half-cross section BB of the figure 10 . It has been understood that the edge (13) comprises two edge elements (13a, 13'a) in the front (3) and rear (5) zones whose width varies along their length.

On notera que selon les variantes illustrées aux figures 9 et 10, la planche de glisse présente deux zones où l'accrochage est maximal localisées dans les extrémités de ladite planche et plus particulièrement dans les zones avant (3) et arrière (5), là où le chant présente une plus grande largeur et est constitué de deux éléments de chant (13'a, 13"a), alors que dans la zone du patin (2), le chant n'est constitué que de l'élément interne de chant (13"a).It will be noted that according to the variants illustrated in Figures 9 and 10 , the gliding board has two areas where the attachment is maximum localized in the ends of said board and more particularly in the front (3) and rear (5) areas, where the edge has a greater width and consists of two singing elements (13'a, 13 "a), whereas in the zone of the pad (2), the edge consists only of the internal singing element (13" a).

Selon la variante illustrée à la figure 11 le chant (13a, 13b) est constitué de deux éléments de chant (13'a, 13"a - 13'b, 13"b) intimement liés, s'étendant longitudinalement, à savoir un élément interne de chant (13"a, 13"b) dont la face latérale interne (14a, 14b) est solidarisée à la face latérale (12a, 12b) du noyau (7) et un élément externe de chant (13'a, 13'b). Notons que comme précédemment, les deux éléments de chant sont solidarisés ensemble par la coopération de formes entres les faces latérales adjacentes (18'a,18"a- 18'b, 18"b), à savoir entre la face latérale interne (18'a, 18'b) de l'élément externe (13'a, 13'b) et la face latérale externe (18"a, 18"b) de l'élément interne (13"a, 13"b). On notera aussi que selon ce mode de réalisation, l'élément interne de chant (13"a, 13"b) présente une ondulation et sa largeur est constante, tandis que l'élément externe de chant (17a, 17b) est tel que sa face externe ne présente pas d'ondulation et suit par exemple la ligne de cote (LC) de la planche de glisse. La figure 5 est une vue selon la demi coupe transversale B-B de la figure 11.According to the variant illustrated in figure 11 the edge (13a, 13b) consists of two intimately connected singing elements (13'a, 13 "a-13'b, 13" b) extending longitudinally, namely an internal vocal element (13 "a , 13 "b) whose inner lateral face (14a, 14b) is secured to the lateral face (12a, 12b) of the core (7) and an outer edge element (13'a, 13'b). Note that as before, the two edge elements are secured together by the cooperation of shapes between the adjacent side faces (18'a, 18 "a-18'b, 18" b), namely between the internal lateral face (18 'a, 18'b) of the outer member (13'a, 13'b) and the outer side face (18 "a, 18" b) of the inner member (13 "a, 13" b). It will also be noted that according to this embodiment, the inner edge element (13 "a, 13" b) has a corrugation and its width is constant, whereas the external edge element (17a, 17b) is such that its outer face does not have any undulation and for example follows the dimension line (LC) of the gliding board. The figure 5 is a view along the half-cross section BB of the figure 11 .

Selon la variante illustrée à la figure 12, le chant (13a, 13b) est constitué au moins dans certaines zones, de deux éléments de chant (13'a, 13"a - 13'b, 13"b) intimement liés, s'étendant longitudinalement, à savoir un élément interne de chant (13"a, 13"b) dont la face latérale interne (14a, 14b) est solidarisée à la face latérale (12a, 12b) du noyau (7), et un élément externe de chant (13'a, 13'b). Notons que comme précédemment, les deux éléments de chant sont solidarisés ensemble par la coopération de formes entres les faces latérales adjacentes (18'a,18"a- 18'b,18"b), à savoir entre la face latérale interne (18'a, 18'b) de l'élément externe (13'a, 13'b) et la face latérale externe (18"a, 18"b) de l'élément interne (13"a, 13"b). On notera aussi que selon ce mode de réalisation, l'élément interne de chant (13"a, 13"b) présente une ondulation, tandis que l'élément externe de chant (13'a, 13'b) n'est localisé que dans certaines zones, pour suivre par sa face externe la ligne de cote (LC) de la planche de glisse. La figure 4 est une vue selon une coupe transversale A-A de la figure 12, tandis que la figure 5 est une vue selon une coupe transversale B-B de la figure 12. On notera que selon la variante de la figure 12, le chant (13) n'est constitué de deux éléments de chant (13a, 13'a) que dans certaines zones du ski, comme par exemple au moins une partie la zone du patin (2) et au moins une partie des zones avant (3) et arrière (5).According to the variant illustrated in figure 12 the edge (13a, 13b) consists at least in certain areas of two intimately connected singing elements (13'a, 13 "a-13'b, 13" b), extending longitudinally, namely an element internal edge (13 "a, 13" b) whose internal lateral face (14a, 14b) is secured to the lateral face (12a, 12b) of the core (7), and an external edge element (13'a, 13'b). Note that as before, the two edge elements are secured together by the cooperation of shapes between the adjacent side faces (18'a, 18 "a-18'b, 18" b), namely between the internal lateral face (18 'a, 18'b) of the outer member (13'a, 13'b) and the outer side face (18 "a, 18" b) of the inner member (13 "a, 13" b). It will also be noted that according to this embodiment, the inner edge element (13 "a, 13" b) has a corrugation, while the outer edge element (13'a, 13'b) is not localized. only in certain areas, to follow by its external face the side line (LC) of the gliding board. The figure 4 is a view in a cross section AA of the figure 12 while the figure 5 is a view in a cross section BB of the figure 12 . It will be noted that according to the variant of figure 12 the edge (13) consists of two edge elements (13a, 13'a) only in certain areas of the ski, such as at least a part of the zone of the shoe (2) and at least a part of the zones front (3) and rear (5).

On a vu précédemment que les deux éléments de chants pouvaient être de couleurs différentes, mais ils pourraient être de matériaux différents, voir de même matériau mais de caractéristiques mécaniques différentes et par exemple l'un des éléments pourrait être tel que son matériau présente des inclusions métalliques ou autre. Notons aussi que la largeur des deux éléments de chant peuvent être de la même largeur dans une coupe transversale, voir de largeur différentes, sachant que l'élément interne de chant sera avantageusement plus nlarge que l'élément externe.We saw previously that the two elements of songs could be of different colors, but they could be of different materials, to see of same material but of different mechanical characteristics and for example one of the elements could be such that its material presents inclusions metal or other. Note also that the width of the two edge elements can be of the same width in a cross section, or of different width, knowing that the internal singing element will advantageously nger greater than the external element.

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. Ainsi, la hauteur (H) des chants pourrait être inférieure à l'épaisseur (E) du noyau (7). De même la planche de glisse pourrait être dissymétrique, notamment en ce qui concerne les chants.Of course, the invention is not limited to the embodiments described and represented by way of examples, but it also includes all the technical equivalents as well as their combinations. Thus, the height (H) of the edges could be less than the thickness (E) of the core (7). Similarly the gliding board could be asymmetrical, especially with regard to the songs.
