Description

L'invention se rapporte au domaine du patin tel que le patin à roulettes, le patin en ligne ou le patin à glace. En particulier, l'invention concerne un patin comprenant une chaussure articulée sur un châssis pour permettre un soulèvement du talon et améliorer ainsi la pratique du patinage sur la surface de glisse.The invention relates to the field of skating such as roller skating, skating in line or ice skating. In particular, the invention relates to a skate comprising a shoe articulated on a chassis to allow a heel lift and thus improving the practice of skating on the sliding surface.

Les patins articulés sont déjà connus de l'art antérieur, notamment dans le domaine du patin à glace, où leur efficacité est maintenant reconnue en patinage de vitesse. Il a été constaté que les patins traditionnels limitent l'extension de la cheville au moment de la poussée afin d'éviter l'accrochage de la pointe du patin avec la surface de glisse. Du coup, cette limitation du mouvement engendre une perte de puissance. De plus, le temps de contact avec la surface de glisse à chaque foulée est diminué. Une structure de patin dans laquelle la chaussure est articulée sur le châssis permet le décollement du talon par rapport au châssis et libère ainsi la cheville. Le patineur peut allonger la cheville sans risque de planter la pointe dans la surface de glisse. Le contact avec la surface de glisse est aussi conservé plus longtemps alors que la cheville est encore en extension.The articulated pads are already known from the prior art, especially in the ice skating, where their effectiveness is now recognized in skating speed. It has been found that traditional skates limit the extension of the ankle at the time of the push to avoid catching the tip of the skate with the sliding surface. Suddenly, this limitation of movement causes a loss of power. In addition, the contact time with the gliding surface with each stride is decreases. A skate structure in which the shoe is articulated on the chassis allows the heel to come off relative to the chassis and thus frees the ankle. The skater can lengthen the ankle without risk of planting the point in the surface of slips. The contact with the sliding surface is also kept longer while the ankle is still extended.

Les systèmes actuels qui proposent une telle possibilité de mobilité du pied par rapport au châssis ne donnent pas entièrement satisfaction. Les systèmes existants apportent une flexibilité de la chaussure se rapprochant plus ou moins du déroulé naturel du pied, mais en contrepartie, ils sont généralement de conception compliquée et ils ont une faible rigidité en torsion. Un exemple illustrant ce problème est donné dans le document WO 96/37269 qui comprend un patin formé de deux sous-châssis mutuellement connectés par des moyens mécaniques du type à biellettes autorisant un déplacement à la fois en rotation et en translation de la chaussure. Un tel système comprend des moyens d'articulation transversaux qui sont fortement sollicités en torsion, notamment dans les phases d'extension. Afin d'obtenir une rigidité suffisante, les pièces doivent être surdimensionnées et réalisées dans des matériaux aux caractéristiques mécaniques élevées. Les patins sont donc assez lourds et de montage compliqué. D'une manière générale, ils sont coûteux à fabriquer et ils sont donc réservés à la compétition.Current systems which offer such a possibility of foot mobility by compared to the chassis are not entirely satisfactory. Existing systems bring a flexibility of the shoe approaching more or less the unwinding natural of the foot, but in return, they are generally designed complicated and they have low torsional rigidity. An example illustrating this problem is given in document WO 96/37269 which comprises a pad formed by two sub-frame mutually connected by mechanical means of the link type allowing a movement both in rotation and in translation of the shoe. A such a system comprises transverse articulation means which are strongly torsional loads, especially in the extension phases. In order to obtain a sufficient rigidity, the parts must be oversized and produced in materials with high mechanical characteristics. The skates are therefore quite heavy and complicated assembly. In general, they are expensive to manufacture and they are therefore reserved for competition.

La demande de brevet EP 0 778 058 A2 concerne un patin à roues en ligne dont la chaussure comprend deux demi-coques rigides, l'une avant, l'autre arrière, articulées entre elles par un pivot disposé transversalement. La demi-coque avant est fixée rigidement sur un châssis comprenant une série de roues alignées. L'un des inconvénients provient de ce que la chaussure a une structure de type rigide ayant tendance à être lourde, inconfortable et chaude. De plus, l'articulation est aussi soumise à des efforts importants provenant de l'augmentation du bras de levier lors de l'extension de la chaussure autour de l'axe de rotation. Patent application EP 0 778 058 A2 relates to an inline skate whose the shoe comprises two rigid half-shells, one front, the other rear, articulated together by a pivot arranged transversely. The front half-shell is rigidly fixed to a chassis comprising a series of aligned wheels. One of the disadvantages comes from the fact that the shoe has a rigid type structure having tends to be heavy, uncomfortable and hot. In addition, the joint is also subject to significant efforts from the increase in the lever arm during the extension of the shoe around the axis of rotation.

D'autres documents ont rapport avec les systèmes de patin articulés. Citons pour exemple les documents suivants DE 78 733 ; DE 297 01 659 U1 ; DE 296 14 090 ; US 1,603,588 ; IT 278004 ; NL 8702068 ; CA 2 155 444 ; EP 0 192 312 A2.Other documents have to do with articulated skid systems. Let's quote for example the following documents DE 78 733; DE 297 01 659 U1; DE 296 14 090; US 1,603,588; IT 278004; NL 8702068; CA 2 155 444; EP 0 192 312 A2.

Il existe donc toujours un besoin visant à proposer un patin simple et économique qui libère proprement la cheville en extension afin d'augmenter le rendement de la poussée lors du patinage, tout en assurant une rigidité suffisante en torsion.There is therefore always a need to offer a simple skate and economical which cleanly releases the ankle in extension in order to increase the thrust performance during skating, while ensuring sufficient rigidity in torsion.

Pour cela l'invention concerne un patin en ligne comprenant un châssis sur lequel est montée une série de roues, et une chaussure reliée à l'avant seulement du châssis de façon à permettre le soulèvement du talon de la chaussure par rapport au châssis lors du patinage. La chaussure comprend une tige souple qui apporte confort, légèreté et souplesse. La tige comprend une portion avant munie d'une base de semelle reliée fixement sur le châssis, et une portion de semelle arrière rigide, indépendante de la portion avant de tige souple, et qui est reliée de manière articulée sur le châssis. En étant reliée sur le châssis, l'articulation procure une bonne rigidité en torsion tout en apportant une liberté en extension de la cheville qui est suffisante.For this, the invention relates to an inline skate comprising a chassis on which is mounted a series of wheels, and a shoe connected to the front only of the frame so as to allow the heel of the shoe to be raised from the chassis during skating. The shoe includes a flexible upper that provides comfort, lightness and flexibility. The rod includes a front portion provided with a base of sole fixedly connected to the chassis, and a portion of rigid rear sole, independent of the front portion of flexible rod, and which is hingedly connected on the chassis. By being connected to the chassis, the joint provides good rigidity in torsion while providing sufficient freedom in extension of the ankle.

Selon une caractéristique complémentaire, la chaussure se compose d'un sous-ensemble de renforcement comprenant un contrefort de talon solidaire de la portion arrière de semelle rigide et d'un collier entourant la cheville et relié sur les côtés du contrefort de talon. Ainsi, les efforts imposés pour basculer la chaussure sont directement transmis par la structure de renforcement de la chaussure. Cela a pour conséquence d'augmenter la puissance transmise sur l'organe de glissement (lame ou roues) lors de la poussée.According to an additional characteristic, the shoe consists of a subset reinforcement comprising a heel counter fixed to the portion back of rigid sole and a collar surrounding the ankle and connected on the sides of the heel counter. Thus, the forces imposed to tilt the shoe are directly transmitted by the reinforcement structure of the shoe. This has consequence of increasing the power transmitted on the sliding member (blade or wheels) when pushing.

Selon une autre caractéristique, la portion de semelle arrière rigide est articulée sur le châssis autour d'un axe de rotation sensiblement transversal et parallèle à la base de support du châssis. L'articulation est ainsi arrangée pour favoriser une poussée perpendiculaire au châssis et participer à la rigidité en torsion de l'ensemble lors de l'extension de la cheville.According to another characteristic, the rigid rear sole portion is articulated on the chassis around an axis of rotation substantially transverse and parallel to the chassis support base. The articulation is thus arranged to favor a thrust perpendicular to the chassis and participate in the torsional rigidity of the assembly when extending the ankle.

Selon une autre caractéristique, la portion de semelle arrière rigide comprend une surface inférieure d'appui sur la base de support du châssis. De plus, la portion de semelle arrière rigide est couplée à un moyen de rappel élastique opposant un couple de résistance élastique tendant à rapprocher la surface inférieure d'appui sur la base de support du châssis lors du soulèvement du talon. Le patineur trouve ainsi un appui stable et solide en position de glisse à plat. Il n'a aussi aucun effort à fournir pour passer d'une position d'extension à une position de glisse à plat; le rappel se faisant de manière automatique lorsque l'organe de glisse (lame ou roues) quitte la surface de glisse.According to another characteristic, the rigid rear sole portion comprises a lower support surface on the support base of the chassis. In addition, the portion rigid rear sole is coupled to an elastic return means opposing a elastic resistance torque tending to bring the lower bearing surface closer to the chassis support base when raising the heel. The skater thus finds a stable and solid support in the flat sliding position. He also has no effort to provide to move from an extended position to a flat sliding position; the reminder is automatically when the sliding member (blade or wheels) leaves the sliding surface.

Selon une autre caractéristique, le moyen de rappel élastique comprend une plaque de flexion élastique logée en recouvrement de la portion avant souple et de la portion arrière de semelle sur laquelle elle s'appuie pour se déformer en flexion. L'avantage réside dans la simplicité et la fiabilité du moyen de rappel mettant en oeuvre un minimum de pièces et dont l'encombrement est réduit.According to another characteristic, the elastic return means comprises a elastic bending plate housed in overlap of the flexible front portion and the rear portion of the sole on which it rests to deform in flexion. The advantage lies in the simplicity and reliability of the reminder means works a minimum of parts and whose size is reduced.

Selon une autre caractéristique avantageuse, la portion avant est reliée à la base de support du châssis par des éléments de fixation localisés dans la zone des orteils de la chaussure. La fixation de l'avant de la chaussure sur le châssis résout le problème lié à la plongée de l'avant-pied sur l'organe de glisse (lame ou roues) ou la surface de glisse pouvant ainsi engendrer des frottements. Il détermine aussi un axe de rotation disposé en retrait de la portion avant qui est fixe ; ceci ayant pour avantage de concentrer les efforts de poussée à un endroit prédéterminé, en particulier au voisinage des métatarses, alors qu'un axe mobile diffuse les efforts de poussée; ce qui entraíne une perte de rendement.According to another advantageous characteristic, the front portion is connected to the base chassis support by fasteners located in the toe area of the shoe. Attaching the front of the shoe to the chassis resolves the problem related to diving the forefoot on the sliding member (blade or wheels) or the sliding surface which can thus generate friction. It also determines an axis of rotation disposed behind the front portion which is fixed; this having for advantage of concentrating the pushing efforts in a predetermined location, particular in the vicinity of the metatarsals, while a moving axis diffuses the forces of thrust; which results in a loss of yield.

Selon une autre caractéristique, la tige souple comprend dans la région du plan vertical passant par l'axe d'articulation une souplesse suffisante permettant la flexion de la tige. L'avantage est de permettre le montage de chaussure à tige, au moins, partiellement souple par opposition aux chaussures à coques rigides telles que celles divulguées dans le document EP 0 778 958.According to another characteristic, the flexible rod comprises in the region of the plane vertical passing through the articulation axis sufficient flexibility allowing bending of the stem. The advantage is to allow the fitting of shoe with upper, at least, partially flexible as opposed to rigid shell shoes such as those disclosed in document EP 0 778 958.

D'autres caractéristiques et avantages de l'invention apparaítront dans la description détaillée qui suit en relation avec les dessins figurant en annexe dans lesquels :

  • la figure 6 est une vue partielle de détail du patin montrant différentes configurations de réglage.
    • Other characteristics and advantages of the invention will appear in the detailed description which follows in relation to the drawings in the appendix in which:
  • Figure 1 is a schematic view of an inline skate according to the invention in the pushing phase;
  • Figure 2 is a schematic view of the shoe of Figure 1 in the flat sliding phase;

  • Figure 5 is a schematic side view similar to Figure 1 but according to a variant of the invention;
  • Figure 6 is a partial detail view of the shoe showing different adjustment configurations.

    • Le patin 1 illustré à la figure 1 comprend une base de chaussure 2 et un train roulant 3 sur lequel est monté la chaussure. Le train roulant s'entend de la partie du patin qui assure le contact avec la surface de glisse. Il comprend généralement un châssis 4 formé d'un profilé en forme de U renversé entre lequel s'étend une série de roues 5 ; lesquelles sont individuellement disposées dans une configuration alignée selon une direction d'extension longitudinale principale.The shoe 1 illustrated in FIG. 1 comprises a shoe base 2 and a train roller 3 on which the shoe is mounted. The running gear means the part of the shoe which ensures contact with the sliding surface. It usually includes a chassis 4 formed by an inverted U-shaped profile between which extends a series of wheels 5; which are individually arranged in an aligned configuration in a main longitudinal extension direction.

    La chaussure peut présenter différentes configurations en fonction des disciplines spécifiques qui lui sont destinées. Néanmoins, l'invention trouve un avantage à utiliser une chaussure à tige souple par opposition aux chaussures a coque dérivées de la pratique du ski alpin. La tige de la chaussure s'entend de la partie de chaussure entourant le pied de l'utilisateur. La tige comprend donc une portion avant 20 recouvrant l'avant du pied, y compris les orteils, et une portion montante 21 qui entoure la cheville et s'étend plus ou moins haut au voisinage du mollet. La souplesse de la tige est essentiellement apportée par le choix de matériaux appropriés. De tels matériaux procurent résistance, confort et respirabilité. Ils peuvent être choisis parmi les tissus, le cuir et les plastiques souples. Toutefois, la tige souple peut être renforcée localement par des portions de renfort en matériau relativement rigide. Par exemple, la portion en pointe de la chaussure est préférablement renforcée d'une pièce en plastique semi-rigide ou rigide procurant une protection des orteils (non représenté). Il faut donc entendre par tige souple, une tige constituée en majorité de portions souples assemblées les unes aux autres, sans toutefois exclure l'assemblage de portions relativement plus rigides.The shoe can have different configurations depending on the specific disciplines intended for him. Nevertheless, the invention finds a advantage of using a shoe with a flexible upper as opposed to shoes with hull derived from alpine skiing. The upper of the shoe means the shoe part surrounding the user's foot. The rod therefore comprises a front portion 20 covering the forefoot, including the toes, and a portion rising 21 which surrounds the ankle and extends more or less high in the vicinity of the calf. The flexibility of the upper is mainly provided by the choice of materials appropriate. Such materials provide strength, comfort and breathability. They can be chosen from fabrics, leather and flexible plastics. However, the flexible rod can be locally reinforced by reinforcing portions of material relatively rigid. For example, the point portion of the shoe is preferably reinforced with a semi-rigid or rigid plastic part providing toe protection (not shown). Soft rod should therefore be understood to mean a rod consisting mainly of flexible portions assembled together, without however, exclude the assembly of relatively more rigid portions.

    La pratique du patinage impose de concevoir une structure de renforcement qui a pour fonction de transmettre les efforts de poussée du patineur vers le sol, mais aussi d'assurer la protection et la sécurité de la jambe qui tiennent compte des sollicitations subies par celle-ci lors de la pratique. Cette structure de renforcement se présente sous forme d'un sous-ensemble 6 qui entoure les zones sensibles du pied. En particulier, le sous-ensemble comprend un contrefort de talon 60 et un collier 61 relié sur les côtés du contrefort par des moyens d'articulation 62.The practice of skating requires designing a reinforcement structure which has the function of transmitting the pushing forces of the skater towards the ground, but also to ensure the protection and safety of the leg which take into account stresses experienced by it during practice. This reinforcement structure is present in the form of a sub-assembly 6 which surrounds the sensitive areas of the foot. In particular, the sub-assembly includes a heel counter 60 and a collar 61 connected on the sides of the buttress by articulation means 62.

    Selon l'invention, la chaussure comprend une portion de semelle arrière 63 qui est suffisamment rigide pour ne pas, ou peu, se déformer lors du mouvement de patinage. Cette portion est indépendante de la tige souple 2 et fait partie intégrante du sous-ensemble de renforcement 6. Par 〈〈 indépendante 〉〉, il faut entendre que la portion est considérée comme structurellement distincte de la tige souple bien qu'elle puisse lui être reliée par des moyens de fixation permanents ou détachables.According to the invention, the shoe comprises a rear sole portion 63 which is rigid enough so that it does not, or only slightly, deform during the movement of skating. This portion is independent of the flexible rod 2 and is an integral part of the reinforcement subset 6. By 〈〈 independent 〉〉, it should be understood that the portion is considered to be structurally distinct from the flexible stem although it can be connected to it by permanent or detachable fixing means.

    Comme l'illustre la figure 1, la portion de semelle arrière 63 comprend une extrémité avant 63a se terminant sous la tige souple, en arrière de la pointe de la chaussure, et qui est reliée au châssis par une articulation 7. De préférence, l'articulation se situe dans la région des métatarses ou légèrement en arrière de la région des métatarses. Selon l'invention, il a été déterminé que c'est dans cette région que l'on obtient le meilleur rendement en puissance. L'articulation correspond, de préférence, à un axe de rotation simple. La portion de semelle rigide 63 peut être intégrale avec le contrefort talon ou, dans une alternative, être constituée d'une partie indépendante reliée par des moyens de liaison tels que par collage, des vis ou des rivets, ou une combinaison de ces moyens.As illustrated in FIG. 1, the rear sole portion 63 includes a front end 63a ending under the flexible rod, behind the tip of the shoe, and which is connected to the chassis by a hinge 7. Preferably, the joint is located in the metatarsal region or slightly behind the metatarsal region. According to the invention, it has been determined that it is in this region that we get the best power output. The articulation corresponds, from preferably a simple axis of rotation. The rigid sole portion 63 can be integral with the heel counter or, in an alternative, be made up of a independent part connected by connecting means such as by gluing, screws or rivets, or a combination of these.

    La portion avant 20 de la tige souple comprend, quant à elle, une portion de semelle 22 qui est reliée de manière fixe au châssis 4. La portion de semelle avant 22 est fixée par des moyens de fixation 23 localisés dans la région des orteils. La portion de semelle se prolonge vers l'arrière par une portion arrière 24 qui repose sur la portion de semelle arrière rigide 63 du sous-ensemble de renforcement. La semelle de la tige est fixée sur le châssis seulement dans la région avant du pied ; c'est-à-dire, en avant de l'articulation 7. De la sorte, la tige souple est forcée de fléchir lors du soulèvement du talon de la chaussure. La flexion s'exerce sensiblement dans le plan vertical passant par l'articulation. Il est donc avantageux de prévoir que la chaussure ait une souplesse suffisante au moins dans cette zone. La tige doit en fait être à la fois résistante aux mouvements de flexion répétés dans cette zone et suffisamment souple pour ne pas gêner la flexion libre de la chaussure. Il faut aussi noter que le talon de la tige souple se déplace dans le contrefort talon rigide 60 de quelques millimètres lors de la flexion de la tige. Pour favoriser ce déplacement, il est prévu que la portion de semelle arrière 24 de la tige souple soit libre par rapport à la portion de semelle rigide 63. La tige peut être couplée au sous-ensemble de renforcement 6 par des moyens tels qu'une sangle 64 ou des moyens supplémentaires de liaison (non représentés) favorisant l'entraínement de la tige en flexion de façon à éviter un décollement du talon de la tige par rapport à la base.The front portion 20 of the flexible rod comprises, for its part, a portion of sole 22 which is fixedly connected to the chassis 4. The front sole portion 22 is fixed by fastening means 23 located in the toe region. The part of the sole is extended towards the rear by a rear portion 24 which rests on the rigid rear sole portion 63 of the reinforcement sub-assembly. The sole of the rod is fixed to the frame only in the front region of the foot; that is to say, in front of the joint 7. In this way, the flexible rod is forced to bend during the heel lift of the shoe. The bending is exerted appreciably in the plane vertical passing through the joint. It is therefore advantageous to provide that the shoe have sufficient flexibility at least in this area. The rod should actually be both resistant to repeated bending movements in this area and sufficiently flexible so as not to hinder the free bending of the shoe. It should also be noted that the heel of the flexible upper moves in the rigid heel counter 60 by a few millimeters during bending of the rod. To encourage this movement, it is expected that the portion of rear sole 24 of the flexible upper is free relative to the sole portion rigid 63. The rod can be coupled to the reinforcement sub-assembly 6 by means such as a strap 64 or additional connecting means (not shown) promoting the entrainment of the rod in bending so as to avoid detachment of the heel from the upper relative to the base.

    La figure 2 montre la chaussure lors d'une configuration de repos sur le châssis ou correspondant à une phase de glisse ou roulement à plat. La portion de semelle arrière 63 du sous-ensemble de renforcement 6 possède une surface inférieure d'appui 63b qui repose sur la base de support 40 du châssis. La base 40 correspond à une surface transversale, de préférence sensiblement plane, reliant les côtés du châssis supportant les roues. Cette base 40 peut s'étendre de façon continue sur toute la longueur du châssis ou, au contraire, ne s'étendre que sur une partie de sa longueur. De part et d'autre de la surface inférieure d'appui 63b, la portion de semelle 63 se prolonge latéralement et vers le bas par deux parois de guidage 63c, 63d (figure 4). Ces deux parois sont espacées transversalement l'une de l'autre d'une distance sensiblement supérieure à la largeur du châssis 4. Ces parois servent à assurer un meilleur guidage de la partie arrière de la chaussure dans le plan longitudinal d'articulation P de la chaussure par rapport au châssis et permet de diminuer le risque de vrillage autour de l'articulation.Figure 2 shows the shoe during a resting configuration on the chassis or corresponding to a sliding or rolling phase. The sole portion rear 63 of the reinforcement sub-assembly 6 has a lower surface 63b support which rests on the support base 40 of the chassis. The base 40 corresponds to a transverse surface, preferably substantially planar, connecting the sides of the chassis supporting the wheels. This base 40 can extend continuously over any the length of the chassis or, on the contrary, only extend over part of its length. On either side of the lower bearing surface 63b, the portion of sole 63 extends laterally and downwards by two guide walls 63c, 63d (Figure 4). These two walls are spaced transversely from one another by distance substantially greater than the width of the chassis 4. These walls serve to ensure better guidance of the rear part of the shoe in the plane longitudinal hinge P of the shoe relative to the chassis and allows reduce the risk of twisting around the joint.

    Comme le montre la figure 3, un élément de rappel élastique 8 équipe, de préférence, le patin pour favoriser le retour en position de repos ou d'appui talon de la chaussure sur le châssis. Ce moyen de rappel oppose un couple de résistance élastique qui tend à rapprocher la surface inférieure d'appui 63b de la portion de semelle rigide 63, sur la base de support 40 du châssis lors du soulèvement du talon. La force de l'élément de rappel doit être suffisante pour permettre ce rapprochement en l'absence d'effort volontaire d'extension de la part du patineur ; de sorte que le train roulant revient en position de repos automatiquement après la poussée, sans que le patineur n'ait à se soucier de la position du train roulant par rapport à sa chaussure.As shown in Figure 3, an elastic return element 8 equips, preferably, the pad to favor the return to the rest position or heel support of the shoe on the chassis. This reminder opposes a resistance couple elastic which tends to bring the lower bearing surface 63b closer to the portion of rigid sole 63, on the support base 40 of the chassis when the heel is raised. The force of the return element must be sufficient to allow this approximation in the absence of a voluntary extension effort on the part of the skater; so that the undercarriage returns to rest position automatically after pushing, without that the skater does not have to worry about the position of the running gear in relation to his shoe.

    Un tel moyen de rappel élastique 8 est, de préférence, une plaque de flexion élastique logée dans la chaussure. Comme le montre la figure 3, la plaque se trouve en recouvrement de la portion arrière rigide 63 sur laquelle elle s'appuie et de la portion avant 20 de tige pour se déformer ainsi en flexion lors d'un soulèvement de la portion arrière par rapport au point d'articulation 7. La plaque peut être logée discrètement sous une semelle interne, par exemple. Il s'agit donc d'un élément simple, fiable et économique à mettre en oeuvre. Bien entendu, d'autres moyens élastiques remplissant une fonction de rappel équivalente peuvent être envisagés sans que l'on sorte de la portée de l'invention. Ainsi, on peut envisager de remplacer la plaque de flexion par des ressorts de torsion montés sur l'axe d'articulation 7.Such elastic return means 8 is preferably a bending plate elastic housed in the shoe. As shown in Figure 3, the plate is located covering the rigid rear portion 63 on which it rests and the front portion 20 of rod so as to deform in bending during a lifting of the rear portion relative to the articulation point 7. The plate can be accommodated discreetly under an insole, for example. It is therefore an element simple, reliable and economical to implement. Of course, other means elastic bands performing an equivalent return function can be envisaged without going beyond the scope of the invention. So we can consider replacing the bending plate by torsion springs mounted on the hinge pin 7.

    La figure 4 illustre l'agencement de la tige par rapport au sous-ensemble de renforcement dans la partie arrière de la chaussure. La portion de tige souple s'insère dans le contrefort talon 60 du sous-ensemble de renforcement 6. Une liaison entre la portion souple 24 interne et la portion de semelle rigide 63 externe n'est pas souhaitable de façon à autoriser un glissement relatif de la tige souple par rapport à la structure de renforcement dans la région de la semelle lors de la flexion. En revanche, une liaison 61a entre la tige et la structure de renforcement est nécessaire, par exemple, au niveau du collier 61, pour maintenir la tige solidaire du sous-ensemble de renforcement.FIG. 4 illustrates the arrangement of the rod relative to the subset of reinforcement in the rear part of the shoe. The flexible rod portion is inserted in the heel buttress 60 of the reinforcement sub-assembly 6. A connection between the flexible portion 24 internal and the rigid sole portion 63 external is not desirable so as to allow relative sliding of the flexible rod relative to the reinforcing structure in the sole region when flexing. In however, a connection 61a between the rod and the reinforcement structure is necessary, for example, at the level of the collar 61, to keep the rod integral with the sub-assembly reinforcement.

    La figure 5 concerne une variante de l'invention dans laquelle la portion de semelle arrière rigide 63 est un élément indépendant de la structure de renforcement et se présente sous forme d'une plaque sur laquelle prend appui la tige 2. La portion arrière de semelle de la tige est, de préférence, liée à la plaque 63 par des moyens de liaison du type coulissant autorisant un mouvement relatif longitudinal avant/arrière lors de la flexion de la tige. De tels moyens peuvent comprendre des fourreaux 63e, 63f, reliés sur la semelle de la tige souple et dans lesquels coulisse la plaque 63. Plusieurs fourreaux peuvent être répartis longitudinalement sur la plaque selon les besoins. Ils ont pour fonctions de maintenir la tige et la plaque 63 solidaire lors de la rotation tout en favorisant un guidage longitudinal relatif de la tige par rapport à la plaque.FIG. 5 relates to a variant of the invention in which the portion of rigid rear sole 63 is an independent element of the reinforcement structure and is in the form of a plate on which the rod 2 rests. The portion rear of the sole of the upper is preferably linked to the plate 63 by means of sliding type link allowing relative longitudinal movement front / rear when bending the rod. Such means may include sleeves 63e, 63f, connected on the sole of the flexible rod and in which the plate 63. Several sleeves can be distributed longitudinally on the plate as required. Their function is to keep the rod and the plate 63 integral during rotation while promoting relative longitudinal guidance of the rod by compared to the plate.

    La structure de renforcement 6 est localisée en partie au moins à l'intérieur de la tige souple comme le montrent les lignes pointillées. Cette structure peut être formée d'un contrefort de talon 60 et d'un élément de support 61 entourant au moins partiellement la cheville. Le contrefort de talon et l'élément de support peuvent être formés d'une seule pièce par moulage d'un plastique rigide.The reinforcing structure 6 is located in part at least inside the flexible rod as shown by the dotted lines. This structure can be formed a heel counter 60 and a support element 61 surrounding at least partially the ankle. The heel counter and the support element can be formed in one piece by molding a rigid plastic.

    La figure 6 montre une vue de détail d'une variante de l'invention dans laquelle il existe des possibilités de réglage de la position longitudinale de la chaussure par rapport au châssis selon différentes configurations. Dans une première configuration, la portion avant 20 de la chaussure comprend un moyen de fixation 23 destiné à coopérer sélectivement avec une série de positions de réception du moyen de fixation espacées longitudinalement l'une de l'autre sur le châssis. Par exemple, le moyen de fixation peut être un ensemble vis 23a / écrou 23b. La vis 23a passe au travers de la portion de semelle avant 22 de la chaussure. Une série de trous 41a, 41b, 41c, sont disposés dans la base 40 du châssis de manière espacée longitudinalement d'un pas prédéterminé p1. Chaque trou correspond à une position sélectionnée de la portion avant 20 de la chaussure dès lors que l'ensemble vis/écrou coopère avec l'un des trous. On peut ainsi déplacer la position avant fixe de la tige souple de la chaussure par rapport au châssis. Pour des raisons de simplification, un seul moyen de fixation 23a été représenté, mais bien entendu, il peut être envisagé plusieurs moyens de fixations espacés transversalement et/ou longitudinalement l'un de l'autre.Figure 6 shows a detailed view of a variant of the invention in which there are possibilities of adjusting the longitudinal position of the shoe relative to the chassis in different configurations. In a first configuration, the front portion 20 of the shoe comprises a fastening means 23 intended to cooperate selectively with a series of positions for receiving the fastening means spaced apart longitudinally from one another on the chassis. For example, the fixing means can be a screw 23a / nut 23b assembly. The screw 23a passes through the front sole portion 22 of the shoe. A series of holes 41a, 41b, 41c, are arranged in the base 40 of the chassis in a longitudinally spaced manner by a predetermined pitch p 1 . Each hole corresponds to a selected position of the front portion 20 of the shoe as soon as the screw / nut assembly cooperates with one of the holes. We can thus move the fixed front position of the flexible upper of the shoe relative to the chassis. For reasons of simplification, a single fixing means 23 has been shown, but of course, it is possible to envisage several fixing means spaced transversely and / or longitudinally from one another.

    Une seconde configuration de réglage peut être proposée pour déplacer longitudinalement le point d'articulation 7 relativement au châssis 4. La position de l'articulation influence, en effet, de manière très significative le rendement de la poussée exercée par le patineur. Le réglage permet d'ajuster la position de l'articulation par rapport à la position relative des métatarses en fonction de la morphologie de chaque patineur. Le réglage est obtenu, par exemple, en prévoyant une série de paliers transversaux 42a, 42b, 42c dans le châssis destinés à la réception de l'axe d'articulation de la portion de semelle rigide 63. Les axes de paliers sont espacés d'un pas prédéterminé p2. Dans une configuration possible, le pas p1 peut être égal au pas p2 ; ce qui permet un déplacement relatif de l'ensemble de la chaussure par rapport au châssis. Dans une variante, p1 et p2 peuvent avoir des valeurs distinctes. D'une manière générale, on peut envisager l'un ou l'autre des réglages, ou les deux en combinaison.A second adjustment configuration can be proposed to move the articulation point 7 longitudinally relative to the chassis 4. The position of the articulation has a very significant effect on the efficiency of the thrust exerted by the skater. The adjustment adjusts the position of the joint relative to the relative position of the metatarsals according to the morphology of each skater. The adjustment is obtained, for example, by providing a series of transverse bearings 42a, 42b, 42c in the chassis intended for the reception of the articulation axis of the rigid sole portion 63. The bearing axes are spaced from a predetermined step p 2 . In a possible configuration, the step p 1 can be equal to the step p 2 ; which allows relative movement of the entire shoe relative to the chassis. Alternatively, p 1 and p 2 can have separate values. In general, one can consider one or other of the settings, or both in combination.
