Description

La présente invention concerne un équipement de sport de glisse sur neige du type constitué par une planche unique présentant une spatule relevée, sur laquelle peuvent être montées deux fixations pour la solidarisation des chaussures avec ladite planche.The present invention relates to snow gliding sports equipment of the type constituted by a single board having a raised spatula, on which two bindings can be mounted for securing the shoes with said board.

On connaît dans l'art antérieur deux types d'engins de glisse pour la neige, mettant en oeuvre une planche unique. Il s'agit des monoskis, tels que décrits par exemple dans le brevet français N° 2604631 ou le brevet américain US-3947049, dans lesquels les deux fixations sont parallèles et sont disposées sur une même ligne transversale, ou les surfs, par exemple divulgué par le brevet français n° FR-2600548 comportant une fixation avant orientée longitudinalement et une position arrière orientée transversalement, l'utilisateur tant placé en position semi-latérale.Two types of gliding devices for snow are known in the prior art, using a single board. These are monoskis, as described for example in French patent No. 2604631 or American patent US-3947049, in which the two bindings are parallel and are arranged on the same transverse line, or the surfboards, for example disclosed by French Patent No. FR-2600548 comprising a front fixing oriented longitudinally and a rear position oriented transversely, the user being placed in a semi-lateral position.

On a également proposé dans l'art antérieur des dispositifs de glisse hybrides. Par exemple, le brevet allemand DE-2557275 divulgue un monoski constitué par une planche sur lequel les fixations sont en position longitudinale décalées l'une derrière l'autre. Pour pallier au manque de maniabilité du dispositif décrit, celui-ci présente un profil convexe, et le skieur utilise une cordelette de guidage fixée à l'avant du monoski, lui permettant de donner une impulsion pour l'entrée en courbe.Hybrid gliding devices have also been proposed in the prior art. For example, German patent DE-2557275 discloses a monoski consisting of a board on which the bindings are in longitudinal position offset one behind the other. To overcome the lack of maneuverability of the device described, it has a convex profile, and the skier uses a guide cord fixed to the front of the monoski, allowing it to give an impulse for entering the curve.

Un autre document, le brevet allemand DE-3903401 décrit un dispositif de glisse.Another document, German patent DE-3903401 describes a sliding device.

On connait également dans l'état de la technique le brevet US3900204 qui divulgue une planche de glisse d'une largeur d'environ 10 à 12 inches, soit 25,4 à 30,5 centimètres, sur laquelle les fixations sont fixées pour former un angle de l'ordre de 45° avec l'axe longitudinal. L'utilisateur se orienté vers l'une des carres, et se tient sensiblement perpendiculairement à l'axe longitudinal de la planche.Also known in the prior art is US Pat. No. 3,900,204 which discloses a gliding board with a width of approximately 10 to 12 inches, or 25.4 to 30.5 centimeters, on which the bindings are fixed to form a angle of around 45 ° with the longitudinal axis. The user is directed to one of the edges, and stands substantially perpendicular to the longitudinal axis of the board.

L'objet de la présente invention est de proposer un nouvel équipement de glisse propre à procurer des sensations différentes de celles produites avec les équipements de l'art antérieur, et susceptible d'être utilisé tant sur la neige poudreuse que sur des pistes damées. Par ailleurs, par rapport au surf, l'invention vise à permettre à l'utilisateur une meilleure vision de la pente, en particulier pendant la phase de fin du virage, où le surfeur en appui sur les orteils se trouve dos à la pente.The object of the present invention is to provide new gliding equipment capable of providing sensations different from those produced with the equipment of the prior art, and capable of being used both on powder snow and on groomed tracks. Furthermore, with respect to surfing, the invention aims to allow the user a better view of the slope, in particular during the end of the turn phase, where the surfer bearing on the toes is back to the slope.

L'invention est définie dans la revendication 1. Les revendications dépendantes 2 à 18 présentent des formes de réalisation particulières de cette invention.The invention is defined in claim 1. Dependent claims 2 to 18 show particular embodiments of this invention.

L'équipement selon la présente invention est plus particulièrement caractérisé en ce qu'une première fixation est positionnée sur la planche de façon non mobile en rotation ni en translation dans une position dans laquelle son axe longitudinal forme avec l'axe longitudinal médian de la planche un angle compris entre 0 degrés et 20 degrés, et de préférence entre 4 et 16 degrés, en ce que la seconde fixation est positionnée sur la planche de façon non mobile en rotation ni en translation dans une position dans laquelle son axe longitudinal forme avec l'axe longitudinal médian de la planche un angle compris entre 0 degrés et 20 degrés, et de préférence entre 4 et 16 degrés, et en ce que lesdites fixations sont disposées en décalage longitudinal, de façon à ce que la distance, mesurée sur l'axe longitudinal, entre la ligne perpendiculaire à l'axe médian longitudinal de la planche passant par l'extrémité avant de la chaussure la plus reculée et la ligne perpendiculaire à l'axe médian longitudinal de la planche passant par l'extrémité arrière de la seconde chaussure soit au plus égale à 100 millimètres.The equipment according to the present invention is more particularly characterized in that a first attachment is positioned on the board in a manner which is not mobile in rotation or in translation in a position in which its longitudinal axis forms with the median longitudinal axis of the board. an angle between 0 degrees and 20 degrees, and preferably between 4 and 16 degrees, in that the second attachment is positioned on the board in a non-movable manner in rotation or in translation in a position in which its longitudinal axis forms with l 'median longitudinal axis of the board an angle between 0 degrees and 20 degrees, and preferably between 4 and 16 degrees, and in that said fasteners are arranged in longitudinal offset, so that the distance, measured on the longitudinal axis, between the line perpendicular to the longitudinal median axis of the board passing through the front end of the rearmost shoe and the perp line ndicular to the longitudinal median axis of the board passing through the rear end of the second shoe is at most equal to 100 millimeters.

Le buste de l'utilisateur est positionné naturellement vers la spatule et ses pieds sensiblement l'un derrière l'autre.The user's bust is naturally positioned towards the spatula and his feet substantially one behind the other.

De préférence, les axes médians des deux fixations sont parallèles, les fixations étant positionnées symétriquement par rapport à un axe oblique formant un angle compris entre 4° et 16° avec l'axe longitudinal de la planche.Preferably, the median axes of the two fasteners are parallel, the fasteners being positioned symmetrically with respect to an oblique axis forming an angle between 4 ° and 16 ° with the longitudinal axis of the board.

Selon un mode de réalisation préféré, la largeur de la planche au niveau de son centre est sensiblement égale à 1,5 fois la largeur d'une chaussure. Avantageusement la largeur de la planche au niveau de son centre est de l'ordre de 140 millimètres.According to a preferred embodiment, the width of the board at its center is substantially equal to 1.5 times the width of a shoe. Advantageously, the width of the board at its center is around 140 millimeters.

Le dispositif de glisse selon ce mode de réalisation présente un confort d'utilisation amélioré et une plus grande maniabilité.The gliding device according to this embodiment has improved comfort of use and greater maneuverability.

Selon une première variante, le milieu de chacune des fixations est positionnées sur l'axe longitudinal médian de la planche, les fixations étant parallèles et positionnées l'une derrière l'autre de façon à ce que la pointe de la fixation avant arrive au niveau de l'un des bords latéraux de la planche, et le talon de la fixation arrière arrive au niveau du bord latéral opposé de la planche, les axes médians des deux fixations étant parallèles et formant avec l'axe longitudinal médian un angle d'environ 7°.According to a first variant, the middle of each of the bindings is positioned on the median longitudinal axis of the board, the bindings being parallel and positioned one behind the other so that the tip of the front binding reaches the level from one of the lateral edges of the board, and the heel of the rear binding arrives at the opposite lateral edge of the board, the median axes of the two bindings being parallel and forming with the median longitudinal axis an angle of approximately 7 °.

Selon une deuxième variante, la pointe de la fixation avant et le talon de la fixation arrière est positionnée sur l'axe longitudinal médian de la planche, la pointe de la fixation arrière et le talon de la fixation avant étant positionnés sur les bords latéraux opposés de la planche. Les pointes et les talons des deux pieds du skieur forment un polygone de sustentation en forme de losange par rapport à l'axe longitudinal médian de la planche, ce qui garantit un équilibrage satisfaisant de l'engin de glisse.According to a second variant, the point of the front binding and the heel of the rear binding is positioned on the median longitudinal axis of the board, the point of the rear binding and the heel of the front binding being positioned on the opposite lateral edges of the board. The points and heels of the two feet of the skier form a support polygon in the shape of a diamond with respect to the median longitudinal axis of the board, which guarantees a satisfactory balancing of the gliding apparatus.

De préférence, la planche comporte une spatule arrondie, une partie centrale munie d'une carre latérale délimitée, de part et d'autre, par des arcs de cercle, et un talon présente de part et d'autre un segment latéral droit.Preferably, the board comprises a rounded spatula, a central part provided with a lateral edge delimited on either side by arcs of a circle, and a heel has a right lateral segment on both sides.

La planche présente de ce fait une "taille de guêpe" ou creusé central. Par "creusé", on entend la distance mesurée selon un axe perpendiculaire à l'axe longitudinal médian du ski, entre:

  • la corde reliant la partie avant la plus large à la partie arrière la plus large,
       et
  • un point situé sur la partie la plus étroite de la planche.
The board therefore has a "wasp waist" or hollowed out central. By "in-ground" means the distance measured along an axis perpendicular to the median longitudinal axis of the ski, between:
  • the cord connecting the widest front part to the widest rear part,
    and
  • a point located on the narrowest part of the board.

Selon un mode de réalisation avantageux, la carre comprise entre le bord concave et le début de la spatule est droite. Ce segment droit procure une attaque progressive lors de la prise de carre, et évite les réactions trop nerveuses de la planche susceptible de déséquilibrer l'utilisateur dont le triangle de sustentation est réduit du fait de la configuration de l'équipement selon l'invention. Avantageusement, la longueur de la partie droite comprise entre le début de la spatule et la partie courbe est comprise entre 2 et 25 centimètres.According to an advantageous embodiment, the edge between the concave edge and the start of the spatula is straight. This straight segment provides a progressive attack when the edge is taken, and avoids overly nervous reactions from the board liable to unbalance the user whose lift triangle is reduced due to the configuration of the equipment according to the invention. Advantageously, the length of the straight part between the start of the spatula and the curved part is between 2 and 25 centimeters.

Selon un mode de réalisation préféré, la fixation avant est positionnée de façon à ce que le milieu de l'avant de la chaussure soient situé sur l'axe longitudinal médian de la planche, la fixation arrière est positionnée de façon à ce que le milieu de l'arrière de la chaussure soient situé sur l'axe longitudinal médian de la planche.According to a preferred embodiment, the front binding is positioned so that the middle of the front of the shoe is located on the median longitudinal axis of the board, the rear binding is positioned so that the middle from the back of the shoe are located on the median longitudinal axis of the board.

Selon une autre variante, la planche présente également une partie droite comprise entre l'extrémité arrière de la partie courbe et le début du talon.According to another variant, the board also has a straight part between the rear end of the curved part and the start of the heel.

De préférence, le centre de courbure de chacun des arcs de cercle se situe sur la droite perpendiculaire à l'axe longitudinal de la planche, coupant celle-ci en un point situé respectivement en avant de la fixation avant et en arrière de la fixation arrière.Preferably, the center of curvature of each of the circular arcs is located on the line perpendicular to the longitudinal axis of the board, cutting the latter at a point respectively in front of the front attachment and behind the rear attachment. .

Dans ce cas, la planche présente une légère asymétrie, les creusés étant décalés longitudinalement.In this case, the board has a slight asymmetry, the hollows being offset longitudinally.

De préférence, le creusé central de la planche est compris entre 1 et 3 centimètres.Preferably, the central hollow of the board is between 1 and 3 centimeters.

Selon une variante, l'équipement selon l'invention comporte une platine de liaison comportant deux fixations pour des chaussures, la planche comportant deux fixations de sécurité longitudinales pour la solidarisation de la platine de liaison avec la planche.According to a variant, the equipment according to the invention comprises a connecting plate comprising two fastenings for shoes, the board comprising two longitudinal safety fasteners for securing the connecting plate to the board.

Selon une variante préférée, la platine de liaison présente une forme de losange, et présente des extrémités avant et arrière propre à coopérer avec des fixations de sécurité de type connues, ladite platine comportant:

  • une cale arrière d'une épaisseur comprise entre 5 et 30 millimètres, ladite cale arrière étant fixée sur la platine de liaison de manière réglable angulairement,
  • une cale avant d'une épaisseur comprise entre 5 et 30 millimètres, ladite cale arrière étant fixée sur la platine de liaison de manière réglable angulairement,
  • deux cales centrales d'une épaisseur comprise entre 0 et 20 millimètres, lesdites cales centrales étant fixées sur la platine de liaison de manière réglable latéralement.
According to a preferred variant, the connection plate has a diamond shape, and has front and rear ends suitable for cooperating with safety fasteners of known type, said plate comprising:
  • a rear wedge with a thickness of between 5 and 30 millimeters, said rear wedge being fixed on the connection plate in an angularly adjustable manner,
  • a front wedge with a thickness of between 5 and 30 millimeters, said rear wedge being fixed on the connection plate in an angularly adjustable manner,
  • two central wedges with a thickness of between 0 and 20 millimeters, said central wedges being fixed to the connection plate in a laterally adjustable manner.

Les moyens de fixation des chaussures sont solidaires des cales.The shoe fastening means are integral with the wedges.

L'équipement selon l'invention dont un exemple de réalisation est décrit en figure 1 comporte une planche (1) présente à sa partie avant une spatule (2) et à sa partie arrière un talon (3). La longueur totale de la planche varie en fonction de la taille et du poids du skieur. A titre d'exemple, la longueur est de 178 centimètres.The equipment according to the invention, an exemplary embodiment of which is described in FIG. 1, includes a board (1) which has a spatula (2) at its front part and a heel (3) at its rear part. The total length of the board varies depending on the size and weight of the skier. As an example, the length is 178 centimeters.

La largeur de la planche (1), mesurée au milieu de la planche, est comprise entre 105 et 150 millimètres, dans le présent exemple de 140 millimètres.The width of the board (1), measured in the middle of the board, is between 105 and 150 millimeters, in the present example 140 millimeters.

La partie centrale (4) présente un axe longitudinal médian (5).The central part (4) has a median longitudinal axis (5).

Latéralement, la planche (1) est délimitée par des carres (20, 21) constituées par des arcs courbes sur la plus grande partie de la longueur de la planche. Le creusé de la planche, dans sa partie médiane, est compris entre 10 et 30 millimètres, de préférence de l'ordre de 25 millimètres. La largeur maximale est de l'ordre de 230 millimètres au niveau du début de la spatule (2) et de l'ordre de 220 millimètres au niveau du début de talon (3).Laterally, the board (1) is delimited by edges (20, 21) formed by curved arcs over the greater part of the length of the board. The hollow of the board, in its middle part, is between 10 and 30 millimeters, preferably of the order of 25 millimeters. The maximum width is of the order of 230 millimeters at the start of the tip (2) and of the order of 220 millimeters at the start of the heel (3).

Le centre du cercle ou le centre des deux foyers déterminant un arc elliptique est placé sur la perpendiculaire (22, 23) l'axe longitudinal médian (5) de la planche (1) passant entre l'avant de la fixation avant et l'arrière de la fixation arrière, dans le cas où la planche est symétrique. Dans le cas où la planche est asymétrique, les centres de l'arc de cercle gauche et droit, ou le milieu des deux foyers définissant les arcs elliptiques gauche et droit sont décalés longitudinalement, et sont par exemple situés respectivement légèrement en arrière et légèrement en avant de l'axe perpendiculaire passant par le milieu des centres des deux fixations (la fixation gauche étant la plus avancée dans l'exemple décrit).The center of the circle or the center of the two focal points determining an elliptical arc is placed on the perpendicular (22, 23) the median longitudinal axis (5) of the board (1) passing between the front of the front fixing and the rear of the rear attachment, if the board is symmetrical. In the case where the board is asymmetrical, the centers of the left and right arc of a circle, or the middle of the two focal points defining the arcs left and right ellipticals are offset longitudinally, and are for example situated slightly behind and slightly in front of the perpendicular axis passing through the middle of the centers of the two fixings (the left fixture being the most advanced in the example described).

Entre le début (25, 26) de la spatule (2) et le début des courbes (20, 21) la planche (1) présente un segment de carres sensiblement rectiligne (27, 28) facilitant la prise de carre et améliorant la stabilité en début de virage. Les deux segments rectilignes (27) et (28) sont de longueur identique, et l'angle β par rapport à l'axe médian longitudinal (5) de la planche (1) est déterminé par la tangente du segment courbe qu'il prolonge.Between the start (25, 26) of the spatula (2) and the start of the curves (20, 21) the board (1) has a substantially straight edge segment (27, 28) facilitating edge grip and improving stability at the start of the turn. The two rectilinear segments (27) and (28) are of identical length, and the angle β relative to the longitudinal median axis (5) of the board (1) is determined by the tangent of the curved segment which it extends .

De la même façon, il est possible de prévoir des segments droits (30, 31) entre la partie arrière des secteurs courbes (20, 21) et le début (32, 33) du talon (3). La longueur de ces segments droits (30, 31) est sensiblement égale à la longueur des segments droits avants (27, 28) soit de l'ordre de 10 centimètres, et de préférence compris entre 2 centimètres et 25 centimètres.Similarly, it is possible to provide straight segments (30, 31) between the rear part of the curved sectors (20, 21) and the beginning (32, 33) of the heel (3). The length of these straight segments (30, 31) is substantially equal to the length of the front straight segments (27, 28) is of the order of 10 centimeters, and preferably between 2 centimeters and 25 centimeters.

La zone médiane de la partie centrale de la planche (1) permet la solidarisation d'une platine de liaison (100) pour la fixation des chaussures de ski ou de surf. Cette platine de liaison comporte deux fixation (6, 7) décrite plus en détail en référence aux figures 2 et 3 dans ce qui suit. L'axe longitudinal (8) de la fixation (6) forme avec l'axe longitudinal (5) de la planche (1) un angle réglable entre 1 degrés et 16 degrés.The central zone of the central part of the board (1) allows the attachment of a connecting plate (100) for fixing ski or snowboard boots. This connecting plate comprises two fasteners (6, 7) described in more detail with reference to Figures 2 and 3 in the following. The longitudinal axis (8) of the fixing (6) forms with the longitudinal axis (5) of the board (1) an adjustable angle between 1 degrees and 16 degrees.

L'axe longitudinal (9) de la fixation arrière (7) forme avec l'axe longitudinal (5) de la planche (1) un angle réglable entre 1 degrés et 16 degrés. Les axes longitudinaux (8, 9), des deux fixations respectivement (6, 7) sont de préférence parallèles.The longitudinal axis (9) of the rear attachment (7) forms with the longitudinal axis (5) of the board (1) an adjustable angle between 1 degrees and 16 degrees. The longitudinal axes (8, 9) of the two fasteners respectively (6, 7) are preferably parallel.

La perpendiculaire (10) à l'axe longitudinal (5) de la planche (1), passant par l'extrémité arrière de la fixation (6) la plus avancée est en arrière, ou au plus confondue, avec la perpendiculaire (11) à l'axe longitudinal (5) de la planche (1), passant par l'extrémité arrière de la fixation (7) la plus reculée. La distance entre les deux perpendiculaire (10) et (11) est comprise entre 0 et 100 millimètres et est de préférence de l'ordre de 50 millimètres.The perpendicular (10) to the longitudinal axis (5) of the board (1), passing through the rear end of the most advanced fixing (6) is behind, or at most combined, with the perpendicular (11) to the longitudinal axis (5) of the board (1), passing through the rear end of the most distant fixing (7). The distance between the two perpendiculars (10) and (11) is between 0 and 100 millimeters and is preferably of the order of 50 millimeters.

La planche (1) comporte deux fixations de sécurité (101, 102) de type connu, disposées sur l'axe longitudinal médian (5) de la planche. Ces fixations sont fixées par vissage, dans une orientation longitudinale. Elles sont écartées d'une distance correspondant sensiblement à la longueur de la platine de liaison (100), qui correspond environ à la longueur de deux chaussures de ski, soit de l'ordre de 500 millimètres.The board (1) has two safety fasteners (101, 102) of known type, arranged on the median longitudinal axis (5) of the board. These fixings are fixed by screwing, in a longitudinal orientation. They are spaced apart by a distance corresponding substantially to the length of the connecting plate (100), which corresponds approximately to the length of two ski boots, ie of the order of 500 millimeters.

La platine de liaison (100) est constituée par une plaque présentant globalement une forme de losange. La longueur, mesurée sur l'axe longitudinal médian, et de 500 millimètres, et la largeur mesurée sur l'axe transversal médian, est légèrement inférieure à la largeur de la planche (1). L'extrémité arrière (103) de la platine (100) est découpée pour présenter une zone arrondie s'étendant sur environ 30 degrés de part et d'autre de l'axe longitudinal médian, avec un rayon de courbure de l'ordre de 30 millimètres, de façon à présenter le profil habituel du talon d'une chaussure de ski.The connecting plate (100) consists of a plate having a generally diamond shape. The length, measured on the median longitudinal axis, and of 500 millimeters, and the width measured on the median transverse axis, is slightly less than the width of the board (1). The rear end (103) of the plate (100) is cut to present a rounded zone extending over approximately 30 degrees on either side of the median longitudinal axis, with a radius of curvature of the order of 30 millimeters, so as to present the usual profile of the heel of a ski boot.

L'extrémité avant (104) de la platine (100) est découpée pour présenter une zone arrondie s'étendant sur environ 25 degrés de part et d'autre de l'axe longitudinal médian, avec un rayon de courbure de l'ordre de 25 millimètres, de façon à présenter le profil habituel de la pointe d'une chaussure de ski.The front end (104) of the plate (100) is cut to present a rounded zone extending over approximately 25 degrees on either side of the median longitudinal axis, with a radius of curvature of the order of 25 millimeters, so as to present the usual profile of the tip of a ski boot.

La partie centrale (105) de la platine de liaison (100) est de forme rectangulaire, d'une longueur d'environ 120 millimètres.The central part (105) of the connecting plate (100) is rectangular, with a length of about 120 millimeters.

La partie arrière (106) de la platine de liaison (100) présente deux lumières (108, 109) en forme d'arcs de cercle coaxiaux, symétriques par rapport à l'axe longitudinal médian.The rear part (106) of the connecting plate (100) has two shaped lights (108, 109) coaxial arcs of circle, symmetrical with respect to the median longitudinal axis.

De même, la partie avant (110) de la platine de liaison (100) présente deux lumières (111, 112) en forme d'arcs de cercle coaxiaux, symétriques par rapport à l'axe longitudinal médian.Likewise, the front part (110) of the connecting plate (100) has two slots (111, 112) in the form of coaxial arcs of a circle, symmetrical with respect to the median longitudinal axis.

La partie centrale (105) présente de part et d'autre de l'axe médian deux lumières respectivement (113, 114) et (115, 116) symétriques deux à deux par rapport à l'axe longitudinal médian.The central part (105) has on either side of the median axis two lumens respectively (113, 114) and (115, 116) symmetrical in pairs with respect to the median longitudinal axis.

Les lumières (113, 115) sont constituées par des arcs de cercle dont le centre de courbure correspond au centre (117) des lumières arrières (108, 109), et dont l'ouverture angulaire couvre un secteur compris entre 1 degré et 16 degrés par rapport à l'axe longitudinal médian de la platine de liaison (100).The lights (113, 115) are constituted by arcs of a circle whose center of curvature corresponds to the center (117) of the rear lights (108, 109), and whose angular opening covers a sector comprised between 1 degree and 16 degrees relative to the median longitudinal axis of the connecting plate (100).

Symétriquement par rapport à l'axe transversal médian, les lumières (114, 116) sont constitués par des arcs de cercle dont le centre de courbure correspond au centre (118) des lumières avant (111, 112), et dont l'ouverture angulaire couvre un secteur compris entre 1 degré et 16 degrés par rapport à l'axe longitudinal médian de la platine de liaison (100).Symmetrically with respect to the median transverse axis, the lights (114, 116) are constituted by arcs of a circle whose center of curvature corresponds to the center (118) of the front lights (111, 112), and whose angular opening covers a sector between 1 degree and 16 degrees relative to the median longitudinal axis of the connecting plate (100).

Les sections des lumières (108, 109, 111 à 116) présentent une première partie inférieure dont la largeur correspond à la section de la tête d'un boulon de fixation, et une partie supérieure dont la largeur correspond à la section du corps dudit boulon de fixation.The sections of the lights (108, 109, 111 to 116) have a first lower part whose width corresponds to the section of the head of a fixing bolt, and an upper part whose width corresponds to the section of the body of said bolt of fixation.

La platine de liaison supporte une paire de fixations respectivement (120, 121) et (122, 123) de chaussures de surf de type connu. Les fixations (120 à 123) sont solidarisées sur la platine de liaison (100) par l'intermédiaire de vis traversant les lumières (108, 109, 111 à 116). Des cales (130 à 133) sont intercalées entre la surface supérieure de la platine de liaison (100) et les fixations respectivement (120 à 123). Les cales avant (130) et arrière (133) intercalées entre la platine et respectivement la fixation de talon (120) de la chaussure la plus reculée (135) et la fixation de la pointe (123) de la chaussure la plus avancée (136) sont plus épaisses que les cales médianes (131, 132).The connecting plate supports a pair of fasteners respectively (120, 121) and (122, 123) of known type of surf shoes. The fasteners (120 to 123) are secured to the connection plate (100) by means of screws passing through the slots (108, 109, 111 to 116). Wedges (130 to 133) are interposed between the upper surface of the connecting plate (100) and the fasteners respectively (120 to 123). The front (130) and rear (133) wedges interposed between the plate and respectively the heel binding (120) of the rearmost shoe (135) and the toe binding (123) of the most advanced shoe (136) are thicker than the middle wedges (131, 132).

L'épaisseur des cales d'extrémités (130, 133) est d'environ 20 millimètres, et l'épaisseur des cales médianes (131, 132) est d'environ 10 millimètres.The thickness of the end wedges (130, 133) is approximately 20 millimeters, and the thickness of the middle wedges (131, 132) is approximately 10 millimeters.

Les cales médianes (131, 132) sont positionnées sur deux lumières médianes opposées, soit (113, 116) ou (115, 114).The middle wedges (131, 132) are positioned on two opposite middle lumens, either (113, 116) or (115, 114).

La forme semi-circulaire des lumières arrières (108, 109) et des lumières avant (111, 112) et la forme allongée des lumières médianes (113 à 116) permet d'ajuster le positionnement angulaire des fixations (120 à 123) entre un angle de 1° et un angle de 16° par rapport à l'axe longitudinal de la platine de liaison (100).The semi-circular shape of the rear lights (108, 109) and the front lights (111, 112) and the elongated shape of the middle lights (113 to 116) allow the angular positioning of the fixings (120 to 123) to be adjusted between a angle of 1 ° and an angle of 16 ° relative to the longitudinal axis of the connecting plate (100).

Les formes des cales (130 à 133) sont déterminées pour coopérer avec le profil des chaussures de surf (135, 136).The shapes of the wedges (130 to 133) are determined to cooperate with the profile of the surf shoes (135, 136).

La platine de liaison (100) présente à sa partie arrière (106) un stop-ski (140) dont la forme et le fonctionnement sont connus dans l'art antérieur.The connecting plate (100) has at its rear part (106) a ski stop (140) whose form and operation are known in the prior art.

La platine de fixation (100) est solidarisée avec la planche (1) par l'intermédiaire de fixations de sécurité (101, 102) garantissant une séparation de la platine de liaison (100) par rapport à la planche si le couple subit par le skieur dépasse une valeur prédéterminée réglable.The fixing plate (100) is secured to the board (1) by means of safety fixings (101, 102) guaranteeing a separation of the connecting plate (100) relative to the board if the torque undergone by the skier exceeds an adjustable predetermined value.

Les figures 3 et 4 représentent une variante de réalisation des fixations pour un engin de glisse selon l'invention, respectivement en vue de coupe et en vue de dessus.Figures 3 and 4 show an alternative embodiment of the fasteners for a sliding device according to the invention, respectively in sectional view and in top view.

Les fixations comportent une butée de sécurité arrière (101) et une butée de sécurité avant (102) de type connu. Ces butées (101, 102) sont décalées latéralement par rapport à l'axe longitudinal médian (5) et forment avec celui-ci un angle α d'environ 7 degrés. Les deux fixations (101, 102) sont écartées d'une distance correspondant sensiblement à la longueur de deux chaussures de ski. Elles sont fixées sur la planche par des vis de façon connue. La butée de retenu arrière (101) est munie d'un stop-ski (140).The bindings include a rear safety stop (101) and a front safety stop (102) of known type. These stops (101, 102) are offset laterally with respect to the median longitudinal axis (5) and form therewith an angle α of approximately 7 degrees. The two fixings (101, 102) are spaced apart by a distance corresponding substantially to the length of two ski boots. They are fixed to the board by screws in a known manner. The rear retaining stop (101) is provided with a ski stop (140).

Les fixations comportent en outre un ensemble de retenue médian (260) constitué par deux butées (261, 262) mobiles longitudinalement par rapport à un rail de guidage (263). La butée de retenue avant (261) coopère avec le talon de la chaussure la plus avancée, et est décalée latéralement, dans l'exemple illustré, vers la gauche de la planche.The fastenings further comprise a median retaining assembly (260) constituted by two stops (261, 262) movable longitudinally relative to a guide rail (263). The front retaining stop (261) cooperates with the heel of the most advanced shoe, and is offset laterally, in the example illustrated, to the left of the board.

La butée de retenue arrière (262) coopère avec la pointe de la chaussure la plus reculée, et est décalée latéralement, dans l'exemple illustré, vers la droite de la planche. Le rail de guidage (263) est disposé sur l'axe longitudinal médian (5) de la planche. Il assure le guidage des éléments de retenue (261, 262) selon une direction sensiblement parallèle à l'axe médian (5).The rear retaining stop (262) cooperates with the tip of the rearmost shoe, and is laterally offset, in the example illustrated, to the right of the board. The guide rail (263) is arranged on the median longitudinal axis (5) of the board. It guides the retaining elements (261, 262) in a direction substantially parallel to the median axis (5).

Un ressort (264) agissant sur deux coulisseaux (266, 267) solidaire respectivement des butées de retenue (261), (262) repoussent celle-ci contre les extrémités des chaussures. Le ressort est taré de façon à permettre le déchaussage lorsque les contraintes s'exerçant sur les jambes du skieur dépasse une valeur prédéterminée.A spring (264) acting on two slides (266, 267) respectively secured to the retaining stops (261), (262) push it against the ends of the shoes. The spring is calibrated so as to allow heaving when the stresses exerted on the skier's legs exceed a predetermined value.

Les figures 5 et 6 représentent une deuxième variante de réalisation des fixations pour un engin de glisse selon l'invention, respectivement en vue de coupe et en vue de dessus.Figures 5 and 6 show a second alternative embodiment of the fasteners for a sliding device according to the invention, respectively in sectional view and in top view.

Les fixations comportent comme dans la variante précédemment décrite une butée de sécurité arrière (101) et une butée de sécurité avant (102) de type connu. Ces butées (101, 102) sont décalées latéralement par rapport à l'axe longitudinal médian (5) et forment avec celui-ci un angle α d'environ 7 degrés. Les deux fixations (101, 102) sont écartées d'une distance correspondant sensiblement à la longueur de deux chaussures de ski. Elles sont fixées sur la planche par des vis de façon connue. La butée de retenu arrière (101) est munie d'un stop-ski (140).The bindings include, as in the previously described variant, a rear safety stop (101) and a front safety stop (102) of known type. These stops (101, 102) are offset laterally with respect to the median longitudinal axis (5) and form therewith an angle α of approximately 7 degrees. The two bindings (101, 102) are spaced apart by a distance corresponding substantially to the length of two ski boots. They are fixed on the board by screws in a known manner. The rear retaining stop (101) is provided with a ski stop (140).

L'ensemble de fixations comporte en outre deux butées médianes (271, 272) supportées par une platine (273) fixée sur la planche (1) par des vis (274, 275).The set of fasteners further comprises two middle stops (271, 272) supported by a plate (273) fixed to the board (1) by screws (274, 275).

Les butées médianes (271, 272) sont articulées par rapport à la platine fixe (273) par l'intermédiaire de deux pivots respectivement (276, 277) sensiblement perpendiculaires à la surface de la planche (1). Les butées (271, 272) sont couplées mécaniquement par des secteurs dentés respectivement (278, 279). Le pivotement de l'une des butées médianes entraîne le pivotement de l'autre butée selon une course angulaire de même amplitude. Un ressort de rappel (280) assure le retour des butées médianes en position de repos dans laquelle elles forment avec l'axe longitudinal médian (5) un angle identique à l'angle que forme l'axe longitudinal des butées de sécurité (101, 102) avec l'axe longitudinal (5), soit environ 7°.The central stops (271, 272) are articulated relative to the fixed plate (273) by means of two pivots respectively (276, 277) substantially perpendicular to the surface of the board (1). The stops (271, 272) are mechanically coupled by toothed sectors respectively (278, 279). The pivoting of one of the middle stops causes the other stop to pivot along an angular stroke of the same amplitude. A return spring (280) returns the central stops to the rest position in which they form with the longitudinal central axis (5) an angle identical to the angle formed by the longitudinal axis of the safety stops (101, 102) with the longitudinal axis (5), about 7 °.

La figure 7 représente une vue de face d'un engin de glisse selon un deuxième mode de réalisation de l'invention.FIG. 7 represents a front view of a sliding device according to a second embodiment of the invention.

La longueur totale de la planche varie en fonction de la taille et du poids du skieur. A titre d'exemple, la longueur est de 178 centimètres. Les dimensions sont indiquées pour un engin de glisse pour adulte. Il est entendu que pour un engin de glisse pour enfant, les dimensions devront être réduites proportionnellement tout en conservant le même ratio.The total length of the board varies depending on the size and weight of the skier. As an example, the length is 178 centimeters. The dimensions are indicated for an adult sliding device. It is understood that for a gliding apparatus for children, the dimensions will have to be reduced proportionally while maintaining the same ratio.

La largeur de la planche (201), mesurée au milieu de la planche, est comprise entre 110 et 150 millimètres, dans le présent exemple de 100 millimètres.The width of the board (201), measured in the middle of the board, is between 110 and 150 millimeters, in the present example 100 millimeters.

La partie centrale (204) présente un axe longitudinal médian (205). La zone médiane de la partie centrale de la planche (201) permet la solidarisation de deux fixations (206, 7) pour la fixation des chaussures de ski ou de surf.The central part (204) has a median longitudinal axis (205). The central zone of the central part of the board (201) allows the attachment of two bindings (206, 7) for fixing ski or snowboard boots.

L'axe longitudinal (208) de la fixation (206) et l'axe longitudinal (209) de la fixation arrière (207) forment avec l'axe longitudinal (205) de la planche (201) un angle d'environ + 7 degrés.The longitudinal axis (208) of the binding (206) and the longitudinal axis (209) of the rear binding (207) form with the longitudinal axis (205) of the board (201) an angle of approximately + 7 degrees.

La perpendiculaire (210) à l'axe longitudinal (205) de la planche (201), passant par l'extrémité arrière de la fixation (206) la plus avancée est en avant, ou au plus confondue, avec la perpendiculaire (211) à l'axe longitudinal (205) de la planche (201), passant par l'extrémité arrière de la fixation (207) la plus reculée. La distance entre l'extrémité arrière de la fixation avant (206) et l'extrémité avant de la fixation arrière (207) est comprise entre 0 et 300 millimètres et est de préférence de l'ordre de 50 millimètres.The perpendicular (210) to the longitudinal axis (205) of the board (201), passing through the rear end of the most advanced fixing (206) is in front, or at most confused, with the perpendicular (211) to the longitudinal axis (205) of the board (201), passing through the rear end of the most remote fixing (207). The distance between the rear end of the front attachment (206) and the front end of the rear attachment (207) is between 0 and 300 millimeters and is preferably of the order of 50 millimeters.

Les centres (212, 213) des fixations respectivement (206, 207) sont décalés latéralement par rapport à l'axe longitudinal médian (205) de la planche (201).The centers (212, 213) of the fasteners respectively (206, 207) are offset laterally with respect to the median longitudinal axis (205) of the board (201).

Latéralement, la planche (201) est délimitée par des carres (220, 221) constituées par des arcs courbes sur la plus grande partie de la longueur de la planche. Le creusé de la planche, dans sa partie médiane, est compris entre 14 et 30 millimètres, de préférence de l'ordre de 25 millimètres. La largeur maximale est de l'ordre de 230 millimètres au niveau du début de la spatule (202) et de l'ordre de 220 millimètres au niveau du début de talon (203).Laterally, the board (201) is delimited by edges (220, 221) formed by curved arcs over the greater part of the length of the board. The hollow of the board, in its middle part, is between 14 and 30 millimeters, preferably of the order of 25 millimeters. The maximum width is of the order of 230 millimeters at the level of the start of the tip (202) and of the order of 220 millimeters at the level of the start of the heel (203).

Le centre du cercle ou le centre des deux foyers déterminant un arc elliptique est placé sur la perpendiculaire (222, 223) l'axe longitudinal médian (205) de la planche (201) passant sensiblement par le milieu des centres des fixations (206 et 207), dans le cas où la planche est symétrique. Dans le cas où la planche est asymétrique, les centres de l'arc de cercle gauche et droit, ou le milieu des deux foyers définissant les arcs elliptiques gauche et droit sont situés respectivement légèrement en arrière et légèrement en avant de l'axe perpendiculaire passant par le milieu des centres des deux fixations (la fixation gauche étant la plus avancée).The center of the circle or the center of the two foci determining an elliptical arc is placed on the perpendicular (222, 223) the median longitudinal axis (205) of the board (201) passing substantially through the middle of the centers of the fixings (206 and 207), in the case where the board is symmetrical. In the case where the board is asymmetrical, the centers of the left and right arc of a circle, or the middle of the two foci defining the left and right elliptical arcs are located slightly back and slightly in respectively before the perpendicular axis passing through the middle of the centers of the two fixings (the left fixation being the most advanced).

Entre le début (225, 226) de la spatule (202) et le début des courbes (220, 221) la planche (201) présente un segment de carres sensiblement rectiligne (227, 228) facilitant la prise de carre et améliorant la stabilité en début de virage. Les deux segments rectilignes (227) et (228) sont de longueur identique, et l'angle β par rapport à l'axe médian longitudinal (205) de la planche (201) est déterminé par la tangente du segment courbe qu'ils prolongent.Between the start (225, 226) of the tip (202) and the start of the curves (220, 221) the board (201) has a substantially straight edge segment (227, 228) facilitating edge grip and improving stability at the start of the turn. The two rectilinear segments (227) and (228) are of identical length, and the angle β relative to the longitudinal median axis (205) of the board (201) is determined by the tangent of the curved segment which they extend .

De la même façon, il est possible de prévoir des segments droits (230, 231) entre la partie arrière des secteurs courbes (220, 221) et le début (232, 233) du talon (203). La longueur de ces segments droits (230, 231) est sensiblement égale à la longueur des segments droits avants (227, 228) soit de l'ordre de 10 centimètres, et de préférence compris entre 2 centimètres et 25 centimètres.In the same way, it is possible to provide straight segments (230, 231) between the rear part of the curved sectors (220, 221) and the beginning (232, 233) of the heel (203). The length of these straight segments (230, 231) is substantially equal to the length of the front straight segments (227, 228) is of the order of 10 centimeters, and preferably between 2 centimeters and 25 centimeters.
