The anchoring/wedging element (40) is mounted on an articulated bar (30). <IMAGE>

Description

La présente invention a pour objet un dispositif de fixation d'une chaussure à organe de glisse tel qu'un ski de fond destiné plus particulièrement à la pratique du pas de patineur ou skating, mais aussi à tout autre organe de glisse permettant la pratique d'un sport de glisse de type skating ou patinage.The present invention relates to a device for attaching a shoe to a sliding member such as a cross-country ski intended more particularly for the practice of skating or skating, but also to any other sliding member allowing the practice of '' a sliding sport of skating or skating type.

Elle concerne plus spécifiquement un dispositif de fixation dans lequel la chaussure est fixée à l'organe de glisse au moins au niveau de la zone métatarso-phalangienne ou de l'éminence du gros orteil.It relates more specifically to a fastening device in which the shoe is fixed to the sliding member at least at the level of the metatarsophalangeal area or the eminence of the big toe.

Par le FR 2 642 980, il est connu un dispositif de fixation polyvalent pour un ski de fond constitué d'une poutre articulée sur le ski, sur laquelle est ancrée la chaussure depuis l'extrémité avant de celle-ci jusque dans une zone située en avant de l'axe d'articulation métatarso-phalangienne. Un tel dispositif assure, par l'intermédiaire de la poutre, une liaison articulée, mais rigide en direction transversale, de la chaussure au ski, plus particulièrement adaptée à la pratique du ski de randonnée dit nordique.By FR 2 642 980, there is known a versatile binding device for cross-country skiing consisting of a beam articulated on the ski, on which the boot is anchored from the front end thereof to a zone located in front of the metatarsophalangeal articulation axis. Such a device ensures, by means of the beam, an articulated, but rigid connection in transverse direction, from the boot to the ski, more particularly suited to the practice of ski touring known as Nordic.

Par ailleurs, il est prévu dans ce même brevet de solidariser la poutre au ski et de ne permettre la rotation de la chaussure qu'autour d'un seul axe de rotation situé à l'avant de la chaussure, dans le but de la pratique du ski de fond proprement dit, que ce soit en technique dite classique ou skating. Un tel dispositif de fixation polyvalent s'avère malheureusement de construction trop compliquée, lourde et coûteuse. Il n'est pas non plus très adapté à la pratique du skating qui requière un bon contrôle du ski par la chaussure.Furthermore, it is provided in this same patent to secure the beam to the ski and to allow the rotation of the boot only around a single axis of rotation located at the front of the boot, for the purpose of practice cross-country skiing proper, whether in classic or skating technique. Such a versatile fixing device unfortunately turns out to be too complicated, cumbersome and expensive. It is also not very suitable for the practice of skating which requires good control of the ski by the shoe.

Il a été également proposé, pour la pratique du pas de patineur en ski de fond ou skating, des dispositifs de fixation spéciaux maintenant toute la zone avant de la chaussure jusqu'à l'axe d'articulation métatarso-phalangienne.It has also been proposed, for the practice of skating step in cross-country skiing or skating, special fixing devices holding the entire front area of the boot up to the metatarsophalangeal axis of articulation.

Un tel dispositif de fixation est par exemple décrit dans le FR 2 595 952 au nom de la demanderesse. Un tel système de fixation avec prise de la chaussure sur le ski sur toute sa zone avant jusqu'au niveau de l'axe d'articulation métatarso-phalangienne est particulièrement adapté à la pratique du skating. En effet, il apporte un meilleur guidage du ski et une meilleure stabilité, une précision accrue, ainsi qu'un bon contact ski/chaussure, et donc un bon touché de neige nécessaire à la pratique du skating.Such a fixing device is for example described in FR 2,595,952 in the name of the applicant. Such a fastening system with grip of the boot on the ski over its entire front region up to the level of the metatarsophalangeal articulation axis is particularly suitable for the practice of skating. Indeed, it provides better ski guidance and better stability, increased precision, as well as good ski / boot contact, and therefore a good touch of snow necessary for the practice of skating.

L'inconvénient d'un tel dispositif de fixation est néanmoins le manque de débattement angulaire entre le pied et le ski ou organe de glisse, le pied étant lié par la fixation de la chaussure jusqu'au niveau des métatarses.The disadvantage of such a fastening device is nevertheless the lack of angular movement between the foot and the ski or sliding member, the foot being linked by the fixing of the boot to the level of the metatarsals.

En effet, certains skieurs de skating préfèrent avoir un débattement plus important de façon à avoir une phase de glisse la plus longue possible et par suite une impulsion plus importante. Le même souhait est valable pour les autres types de sport de patinage.Indeed, some skating skiers prefer to have a greater clearance so as to have a gliding phase as long as possible and therefore a greater impulse. The same wish holds true for other types of skating sport.

Le but de la présente invention est donc de fournir un dispositif amélioré de fixation pour organe de glisse de type patinage et conciliant les deux exigences contradictoires, d'assurer une prise de la chaussure jusqu'au niveau des métatarses et d'autoriser un débattement angulaire suffisant entre la chaussure et l'organe de glisse.The object of the present invention is therefore to provide an improved fastening device for a sliding type skating member and reconciling the two contradictory requirements, to ensure that the boot grips up to the metatarsal level and to allow angular movement sufficient between the shoe and the sliding member.

Ce but est atteint dans le dispositif selon l'invention qui est du type comportant des moyens de calage/ancrage de la chaussure dans une zone d'ancrage de celle-ci allant sensiblement de l'extrémité avant de la chaussure jusqu'au niveau de la zone d'articulation métatarso-phalangienne ou en avant de celle-ci, par le fait qu'il comporte des moyens de basculement des moyens de calage/ancrage, ces moyens de basculement étant disposés dans la zone d'ancrage de la chaussure, et ces moyens de basculement étant conçus de façon à permettre un angle de débattement déterminé de l'ensemble de la chaussure par rapport à l'organe de glisse.This object is achieved in the device according to the invention which is of the type comprising means for wedging / anchoring the shoe in an anchoring zone thereof going substantially from the front end of the shoe to the level of the metatarsophalangeal articulation zone or in front of it, by the fact that it comprises means for tilting wedging / anchoring means, these tilting means being disposed in the zone for anchoring the shoe, and these tilting means being designed so as to allow a determined angle of movement of the whole shoe with respect to the sliding member.

De cette façon, bien que la chaussure soit maintenue dans toute sa zone avant sensiblement jusqu'au niveau des métatarses, une possibilité de débattement supplémentaire du pied par rapport à l'organe de glisse est offerte. Il en résulte que la phase de glisse peut être poursuivie plus longtemps et que l'impulsion est améliorée.In this way, although the shoe is held in its entire front zone substantially up to the level of the metatarsals, a possibility of additional movement of the foot relative to the sliding member is offered. As a result, the gliding phase can be continued longer and the impulse is improved.

Selon un mode de réalisation avantageux, l'angle de rotation maximum des moyens de calage/ancrage est compris entre 5 et 30°. Une telle disposition limite le jeu inhérent au basculement des moyens de calage/ancrage et permet de garantir le guidage et la stabilité nécessaire pour la pratique du skating/patinage.According to an advantageous embodiment, the maximum angle of rotation of the setting / anchoring means is between 5 and 30 °. Such an arrangement limits the play inherent in the tilting of the wedging / anchoring means and makes it possible to guarantee the guidance and the stability necessary for the practice of skating / skating.

Lorsqu'un des moyens de calage/ancrage de la chaussure est constitué par un verrouillage articulé de type charnière, il est avantageux que l'axe du système de verrouillage soit également l'axe de pivotement de l'ensemble des moyens de calage/ancrage.When one of the wedging / anchoring means of the boot consists of an articulated hinge-type locking, it is advantageous that the axis of the locking system is also the pivot axis of all of the wedging / anchoring means .

De toute façon, l'invention sera mieux comprise et les caractéristiques de celle-ci seront mises en évidence à l'aide de la description qui suit en référence au dessin schématique annexé dans lequel :

  • la figure 1 est une vue en coupe longitudinale partielle du dispositif de fixation selon l'invention avec une chaussure de ski de fond associée,
  • la figure 2 est une vue similaire à la figure 1 montrant l'angle de débattement possible,
  • la figure 3 est une vue similaire à la figure 1 d'un dispositif de fixation selon un autre mode de réalisation,
  • la figure 4 est une vue similaire à la figure 1 d'un dispositif de fixation selon encore un autre mode de réalisation.
In any case, the invention will be better understood and the characteristics thereof will be demonstrated using the description which follows with reference to the appended schematic drawing in which:
  • FIG. 1 is a view in partial longitudinal section of the binding device according to the invention with an associated cross-country ski boot,
  • FIG. 2 is a view similar to FIG. 1 showing the possible angle of movement,
  • FIG. 3 is a view similar to FIG. 1 of a fixing device according to another embodiment,
  • Figure 4 is a view similar to Figure 1 of a fixing device according to yet another embodiment.

Les figures 1 et 2 illustrent l'application de l'invention au verrouillage sur un organe de glisse pour la pratique du skating d'une chaussure 10 présentant deux axes d'ancrage 11, 12, l'un des axes 11 étant situé à l'extrémité avant de la chaussure, et le second axe 12 étant situé sensiblement au niveau de la zone d'articulation métatarso-phalangienne ou en avant de celle-ci.Figures 1 and 2 illustrate the application of the invention to locking on a sliding member for the practice of skating a shoe 10 having two anchoring axes 11, 12, one of the axes 11 being located at the 'front end of the shoe, and the second axis 12 being located substantially at the level of the metatarsophalangeal articulation zone or in front thereof.

Une position préférée de l'axe 12 est située entre 30 et 60 mm à l'arrière de la face avant 14 de la chaussure. Ces deux axes 11, 12 délimitent la zone de calage/ancrage 15 de la chaussure.A preferred position of the axis 12 is located between 30 and 60 mm behind the front face 14 of the shoe. These two axes 11, 12 delimit the wedging / anchoring zone 15 of the shoe.

Le dispositif de fixation 20 est constitué essentiellement d'une embase 21 destinée à être fixée sur le ski 1, d'une poutre 30 articulée sur l'embase 21 autour d'un axe transversal 33, d'un chariot de verrouillage 40 monté déplacable longitudinalement à l'intérieur de la poutre 30 et d'un système de verrouillage 50 à genouillère de type connu en soi.The fixing device 20 essentially consists of a base 21 intended to be fixed on the ski 1, of a beam 30 articulated on the base 21 around a transverse axis 33, of a locking carriage 40 mounted movable longitudinally inside the beam 30 and a locking system 50 with a toggle joint of a type known per se.

Le système de verrouillage à genouillère est constitué d'un coulisseau 51, déplacable en direction longitudinale du ski, le long d'une glissière non représentée sur le dessin, et qui est articulé en 43 sur le chariot 40.The toggle locking system consists of a slide 51, movable in the longitudinal direction of the ski, along a slide not shown in the drawing, and which is articulated at 43 on the carriage 40.

Ce coulisseau 51 est maintenu en position de verrouillage de la chaussure par un fil ressort 60 en forme de U articulé, d'une part, sur une partie fixe de l'embase 21 du dispositif par sa partie médiane 61, et, d'autre part, à chacune de ses extrémités 62 sur un lever de déverrouillage 70 en forme de chape qui est lui-même articulé en 71 sur le coulisseau 51.This slider 51 is held in the boot locking position by a U-shaped spring wire 60 articulated, on the one hand, on a fixed part of the base 21 of the device by its middle part 61, and, on the other part, at each of its ends 62 on an unlocking lever 70 in the form of a yoke which is itself articulated at 71 on the slide 51.

L'ensemble 51, 60, 70, constitue un système à genouillère dont les axes sont constitués par les axes 61, 62 et 71, les deux axes 61, 71, définissant la ligne de point mort de la genouillère.The assembly 51, 60, 70 constitutes a toggle joint system, the axes of which consist of the axes 61, 62 and 71, the two axes 61, 71, defining the neutral line of the knee joint.

De façon connue en soi, le blocage de la genouillère est obtenu lorsque l'axe d'articulation défini par 62 passe en-dessous de la ligne de point mort définie par les axes 61, 71.In a manner known per se, the locking of the toggle joint is obtained when the articulation axis defined by 62 passes below the dead center line defined by the axes 61, 71.

Le verrouillage du système est obtenu par déplacement vers l'arrière, c est-à-dire vers la droite dans le dessin, du coulisseau 51, le coulisseau entraînant dans son déplacement dans cette direction le chariot de verrouillage 40.The locking of the system is obtained by moving backwards, that is to say to the right in the drawing, of the slider 51, the slider causing the locking carriage 40 to move in this direction.

Inversement, le déverrouillage est obtenu par pivotement du levier de déverrouillage 70 dans le sens horaire, autour de son axe 71, ce déplacement entraînant le coulissement vers l'avant du coulisseau 51, et par conséquent du chariot de verrouillage 40.Conversely, the unlocking is obtained by pivoting the unlocking lever 70 clockwise around its axis 71, this displacement causing the slide 51, and consequently of the locking carriage 40, to slide forward.

Le chariot de verrouillage 40 comporte deux crochets 41, 42, ayant sensiblement la forme d'un C ouvert vers l'arrière.The locking carriage 40 has two hooks 41, 42, having substantially the shape of a C open towards the rear.

Chacun des crochets 41, 42, coopère à la façon d'une mâchoire/contre mâchoire avec une face d'appui fixe respectivement 31, 32, pour le verrouillage d'un axe associé respectivement 11, 12, de la chaussure.Each of the hooks 41, 42 cooperates in the manner of a jaw / against jaw with a fixed bearing face respectively 31, 32, for locking an associated axis respectively 11, 12, of the shoe.

Ainsi que le montrent les figures, la face d'appui 31 est verticale tandis que la face d'appui 32 présente une légère pente, de façon à permettre un déclenchement ainsi qu'on le verra plus loin. Ces deux faces d'appui 31, 32, sont réalisées sur la poutre 30 articulée sur l'embase 21. Le crochet 42 comporte également une légère rampe 44 formant avec la face d'appui 32 une sorte de Vé permettant un chaussage automatique.As shown in the figures, the bearing face 31 is vertical while the bearing face 32 has a slight slope, so as to allow tripping as will be seen below. These two bearing faces 31, 32 are produced on the beam 30 articulated on the base 21. The hook 42 also includes a slight ramp 44 forming with the bearing face 32 a kind of Vee allowing automatic fitting.

Le crochet 41 est solidaire du chariot de verrouillage 40, tandis que le crochet 42 est monté déplacable en direction longitudinale sur ce chariot 40.The hook 41 is integral with the locking carriage 40, while the hook 42 is mounted displaceable in the longitudinal direction on this carriage 40.

Un ressort 45 sollicite en permanence le crochet 42 vers l'arrière de la fixation, c'est-à-dire en direction de la face d'appui 32, dans la position de verrouillage de l'axe 12.A spring 45 permanently urges the hook 42 towards the rear of the binding, that is to say in the direction of the bearing face 32, in the locking position of the axis 12.

Par conséquent, en cas d'un effort trop important s'exerçant sur l'axe 12, celui-ci peut glisser vers le haut le long de la rampe 32 en repoussant le crochet mobile 42 vers l'avant, à l'encontre de la force du ressort 45, jusqu'à être libéré de son logement.Consequently, in the event of an excessive force exerted on the axis 12, the latter can slide up along the ramp 32 by pushing the movable hook 42 forwards, against the force of the spring 45, until it is released from its housing.

Inversement, cette construction permet également un chaussage automatique de l'axe 12 à l'aide du Vé de chaussage constitué par les rampes 44, 32, l'axe 12 repoussant le crochet 42 à l'encontre de l'action du ressort 45.Conversely, this construction also allows automatic fitting of the axis 12 with the aid of the fitting V formed by the ramps 44, 32, the axis 12 pushing the hook 42 against the action of the spring 45.

Une butée 25 solidaire de l'embase 21 est par ailleurs prévue pour limiter le pivotement vers le haut de la poutre articulée 30. Un ressort 26 interposé entre la poutre et cette butée sollicite par ailleurs cette poutre vers le bas, dans une position de rotation "nulle" montrée à la figure 1.A stop 25 integral with the base 21 is also provided to limit the upward pivoting of the articulated beam 30. A spring 26 interposed between the beam and this stop also biases this beam downwards, in a "zero" rotation position shown in FIG. 1.

Les axes 33 et 43 sont disposés de façon à coincider en position de verrouillage du chariot 40, de façon à permettre une rotation simultanée de la poutre 30 et du chariot 40 autour de leur axe commun 33, 43, dans cette position de verrouillage.The axes 33 and 43 are arranged so as to coincide in the locked position of the carriage 40, so as to allow simultaneous rotation of the beam 30 and the carriage 40 around their common axis 33, 43, in this locked position.

Ainsi que le montre clairement la comparaison des figures 1 et 2, le dispositif de fixation constitué par le chariot 40 et la poutre 30 peut pivoter vers le haut et assurer ainsi à l'ensemble de la chaussure un débattement angulaire a supplémentaire apte à prolonger la phase de glisse. On notera qu'il s'agit bien ici d'un réel débattement angulaire de l'ensemble de la chaussure par rapport au ski qui réalise donc un réel compromis entre une prise sur toute une zone avant de la chaussure tel que connue par le FR 2 595 952 et une articulation totale, néfaste à un bon guidage, de la chaussure sur le ski comme dans le FR 2 642 980.As clearly shown in the comparison of FIGS. 1 and 2, the fastening device constituted by the carriage 40 and the beam 30 can pivot upwards and thus provide the whole of the shoe with an additional angular movement able to extend the sliding phase. It will be noted that this is indeed a real angular displacement of the whole of the boot relative to the ski which therefore achieves a real compromise between a grip over an entire front area of the boot as known by the FR 2,595,952 and a total articulation, detrimental to good guidance, of the boot on the ski as in FR 2 642 980.

La butée 25 qui limite la course de la poutre articulée est choisie de façon à permettre un angle de rotation maximum compris entre 5 et 30° et de préférence compris entre 10 et 20°.The stop 25 which limits the stroke of the articulated beam is chosen so as to allow a maximum angle of rotation of between 5 and 30 ° and preferably between 10 and 20 °.

L'axe d'articulation 33, 43, peut être déplacé vers l'arrière jusqu'à une position correspondant à celle de l'axe 12.The articulation axis 33, 43 can be moved backwards to a position corresponding to that of the axis 12.

C'est l'exemple de réalisation montré dans la figure 3.This is the example of embodiment shown in Figure 3.

Dans ce cas, le dispositif de fixation 120 a exactement le même type de construction, à savoir une embase fixe 121, une poutre 130 articulée sur l'embase autour d'un axe 133, un chariot de verrouillage 140 monté déplaçable longitudinalement à l'intérieur de la poutre 130 et dont le déplacement est commandé par un coulisseau 151, lui même commandé par un système de verrouillage à genouillère 160, 170.In this case, the fixing device 120 has exactly the same type of construction, namely a fixed base 121, a beam 130 articulated on the base around an axis 133, a locking carriage 140 mounted movable longitudinally to the inside the beam 130 and whose movement is controlled by a slide 151, itself controlled by a toggle locking system 160, 170.

Bien qu'ayant des formes différentes du fait de la position de l'axe de rotation 133, 143, les éléments ayant la même fonction sont donc désignés par des références identiques augmentées de 100.Although having different shapes due to the position of the axis of rotation 133, 143, the elements having the same function are therefore designated by identical references increased by 100.

La différence essentielle réside dans cette position de l'axe d'articulation 133, 143, commun à la poutre 130 et au chariot de verrouillage 140, au niveau de l'extrémité arrière de la zone d'ancrage, position qui permet notamment d'avoir un angle de débattement a plus grand.The essential difference lies in this position of the hinge pin 133, 143, common to the beam 130 and to the locking carriage 140, at the rear end of the anchoring zone, a position which allows in particular to have a greater angle of travel.

Dans ce mode de réalisation, la butée limitant le débattement angulaire est constituée par la surface supérieure du ski 1 ou de l'embase 121, et la position de rotation "nulle" est celle représentée à la figure 3 où le ressort 126 situé à l'avant du dispositif de fixation sollicite la poutre articulée 130 vers le haut.In this embodiment, the stop limiting the angular movement is constituted by the upper surface of the ski 1 or of the base 121, and the "zero" rotation position is that shown at Figure 3 where the spring 126 located at the front of the fixing device biases the articulated beam 130 upwards.

Selon l'effet recherché, il est possible de déplacer l'axe d'articulation de la poutre dans toute position intermédiaire entre l'extrémité avant 14 de la chaussure et la limite arrière de la zone de calage/ancrage 115 de la chaussure.Depending on the desired effect, it is possible to move the articulation axis of the beam in any intermediate position between the front end 14 of the shoe and the rear limit of the wedging / anchoring zone 115 of the shoe.

Un tel axe d'articulation peut notamment être disposé dans une position médiane par rapport aux deux extrémités d'une telle zone. Il peut également être confondu avec l'un des axes de verrouillage du dispositif de fixation.Such a hinge pin can in particular be arranged in a middle position relative to the two ends of such a zone. It can also be confused with one of the locking axes of the fixing device.

La figure 4 illustre un mode de réalistion simplifié dans lequel la chaussure est maintenue non pas par le biais d'axes de verrouillage, mais par le biais d'un plot de verrouillage 242 orienté vers l'arrière et coopérant avec un évidement associé 212 de la chaussure et d'un système d'accroche 241 de type connu en soi coopérant avec une boucle d'accrochage 211 de la chaussure.FIG. 4 illustrates a simplified embodiment in which the shoe is held not by means of locking pins, but by means of a locking stud 242 oriented towards the rear and cooperating with an associated recess 212 of the shoe and an attachment system 241 of a type known per se cooperating with an attachment loop 211 of the shoe.

La zone d'accroche 215 de la chaussure est donc délimitée, à l'avant, par la boucle 211 et à l'arrière par l'évidement 212.The grip zone 215 of the shoe is therefore delimited, at the front, by the buckle 211 and at the rear by the recess 212.

Dans ce cas, le débattement des moyens d'ancrage/calage (211, 212, 241, 242) est obtenu par simple interposition d'une couche de matériau élastique 230 entre la surface supérieure du ski 1 et ces moyens d'ancrage/calage.In this case, the movement of the anchoring / wedging means (211, 212, 241, 242) is obtained by simple interposition of a layer of elastic material 230 between the upper surface of the ski 1 and these anchoring / wedging means .

Une telle couche peut être constituée en tout matériau élastique connu en soi. De préférence, la couche de matériau élastique aura une épaisseur comprise entre 10 et 20 mm.Such a layer can be made of any elastic material known per se. Preferably, the layer of elastic material will have a thickness of between 10 and 20 mm.

Des moyens de type butée (non représentés sur le dessin) pourront être prévus pour empêcher tout déplacement en direction transversale de cette couche élastique.Means of the abutment type (not shown in the drawing) may be provided to prevent any displacement in the transverse direction of this elastic layer.

Une telle solution est particulièrement intéressante dans le cas où un faible angle de débattement est souhaité.Such a solution is particularly advantageous in the case where a small deflection angle is desired.

Bien entendu, l'invention n'est pas limitée au seul exemple d'application indiqué et peut être utilisée pour la liaison d'une chaussure avec tout organe de glisse de type patin, patin à glace, patin à roues en ligne, ski de skating...Of course, the invention is not limited to the sole example of application indicated and can be used for the binding of a shoe with any sliding member of the skate, ice skate, inline skate, inline ski type. skating ...
