Description

CRAMPON POLYVALENT POUR CHAUSSURE  POLYVALENT CRAMPON FOR SHOE
Domaine technique Technical area
La présente invention porte sur un crampon pour chaussure, en particulier sur un crampon polyvalent dont l'orientation peut être modifiée par rapport à la chaussure, afin d'adapter facilement et rapidement les appuis de la chaussure en fonction du terrain et/ou des appuis recherchés par son utilisateur. The present invention relates to a shoe cleat, in particular to a versatile cleat whose orientation can be modified with respect to the boot, in order to easily and quickly adapt the supports of the shoe according to the terrain and / or supports searched by its user.
Technique antérieure Prior art
Les chaussures à crampons sont largement utilisées en sports pour faciliter l'accrochage de la chaussure. Les crampons permettent d'éviter qu'un joueur ne glisse lorsqu'il change soudainement ses appuis. Spiked shoes are widely used in sports to facilitate the attachment of the shoe. The crampons prevent a player from slipping when he suddenly changes his bearings.
Par exemple, dans le rugby, les joueurs doivent pouvoir se mouvoir rapidement sur le terrain, changer brusquement de direction pour éviter un joueur ou avoir des appuis solides pour stopper la course d'un adversaire. Les chaussures de sport à crampons actuellement utilisées offrent relativement peu de choix dans l'agencement des crampons sur une chaussure. Or, dans une équipe de rugby, il est attribué à chaque joueur un poste particulier sur le terrain. Par exemple, les trois quarts ont principalement besoin de vitesse et d'accroché maximale dans leurs appuis latéraux lors de changement de direction, les piliers ont besoin de plus de poussée lors de la mêlée, mais aussi de stabilité latérale. De fait, chaque joueur souhaite une chaussure dont les propriétés d'accroché sur le terrain lui conviennent spécifiquement. Il est donc judicieux de proposer un crampon facilement adaptable sur une chaussure de sport, pour répondre à l'attente de chaque joueur. L'accroche d'un crampon dépend notamment de la nature du terrain, de sorte que les joueurs sont amenés à changer un ou plusieurs crampons de leur chaussure en fonction de la nature du terrain et/ou des conditions météorologiques. For example, in rugby, players must be able to move quickly on the court, change direction abruptly to avoid a player or have strong support to stop an opponent's race. Currently used spike sports shoes offer relatively little choice in the arrangement of crampons on a shoe. However, in a rugby team, each player is assigned a particular position in the field. For example, three quarters of them need speed and maximum hooking in their side supports when changing direction, the pillars need more thrust during the melee, but also lateral stability. In fact, each player wants a shoe whose properties of hanging on the ground suit him specifically. It is therefore wise to offer a crampon easily adaptable on a sports shoe, to meet the expectations of each player. The hook of a crampon depends in particular on the nature of the ground, so that the players are led to change one or more crampons of their shoe depending on the nature of the terrain and / or weather conditions.
Le but de la présente invention est de proposer un crampon pour chaussure, s' adaptant aisément à une chaussure en fonction des appuis recherchés par son utilisateur, du sol et des conditions climatiques, afin d'offrir une meilleure accroche et un meilleur confort d'utilisation. The object of the present invention is to provide a shoe spike, adapting easily to a shoe according to the support sought by its user, soil and weather conditions, to provide better grip and comfort of use.
Exposé de l'invention Presentation of the invention
Pour atteindre les objectifs mentionnés ci-dessus, la présente invention propose un crampon polyvalent pour chaussure comportant une face avant et une face arrière, s'étendant entre une base et un sommet du crampon. Autrement dit, entre la base et le sommet du crampon s'étend une paroi latérale comprenant la face avant et la face arrière du crampon. En d'autres termes, la face avant et la face arrière sont jointes de manière à former une paroi latérale entourant la base du crampon. L'invention se caractérise en ce que le sommet est excentré par rapport à la base du crampon et en ce que le crampon comporte deux cavités séparées par une paroi intermédiaire, chaque cavité étant ouverte à la fois sur le sommet et la face arrière du crampon de manière à favoriser un détachement naturel de la terre lors du retrait du crampon du sol. Autrement dit, chaque cavité est ouverte à la fois sur le sommet et la face arrière du crampon de sorte à ne pas avoir de face en vis-à-vis. Par les termes « faces en vis-à-vis », on entend deux faces en regard formant un angle inférieur à 30°. Ce mode de réalisation permet avantageusement de former des cavités ne comportant pas de faces en vis-à-vis, favorables à une accumulation de terre pris en étau entre deux faces en regard. À l'inverse, l'invention propose des cavités ouvertes sur trois de leurs côtés pour favoriser un phénomène de détachement naturel de la terre remplissant les cavités lorsque le crampon est retiré du sol. Selon un mode de réalisation préféré de l'invention, les faces d'une même cavité qui sont sécantes à la base du crampon forment un angle favorisant un détachement naturel de la terre présente dans ladite cavité. De préférence, les faces d'une même cavité qui sont sécantes à la base du sommet forment un angle compris entre 300 et 120°, de préférence compris entre 8o° et ioo° ou de l'ordre de 90°. To achieve the objectives mentioned above, the present invention provides a versatile shoe lug having a front face and a rear face, extending between a base and a crampon top. In other words, between the base and the top of the crampon extends a side wall comprising the front face and the rear face of the crampon. In other words, the front face and the back face are joined to form a side wall surrounding the base of the crampon. The invention is characterized in that the top is eccentric with respect to the base of the crampon and in that the crampon comprises two cavities separated by an intermediate wall, each cavity being open on both the top and the rear face of the crampon. in order to favor a natural detachment of the earth during the removal of the crampon from the ground. In other words, each cavity is open both on the top and the rear face of the crampon so as not to have face vis-à-vis. By the terms "vis-à-vis faces" means two facing faces forming an angle less than 30 °. This embodiment advantageously makes it possible to form cavities that do not have faces facing each other, which are favorable for an accumulation of earth taken in a vice between two facing faces. Conversely, the invention proposes cavities open on three of their sides to promote a phenomenon of natural detachment of the earth filling the cavities when the crampon is removed from the ground. According to a preferred embodiment of the invention, the faces of the same cavity which are intersecting at the base of the crampon form an angle favoring a natural detachment of the earth present in said cavity. Preferably, the faces of the same cavity which are intersecting at the base of the apex form an angle of between 0 ° and 120 °, preferably between 80 ° and 100 ° or of the order of 90 °.
Par le terme « excentré », on entend le fait que le sommet du crampon est décalé par rapport à sa base, afin que leurs centres définissent une droite formant un angle aigu avec la base. En d'autres termes, le crampon s'étend de façon oblique par rapport à sa base, de sorte qu'en modifiant l'orientation du crampon par rapport à sa direction de déplacement dans le sol, on contrôle l'intensité de la force qui s'oppose à son déplacement. Par conséquent, l'invention propose également un crampon polyvalent, dont les propriétés de pénétration et d'accroché dans le sol peuvent facilement être adaptées en fonction du type d'appui souhaité par son utilisateur, de la nature du sol et des conditions climatiques. By the term "eccentric" is meant that the top of the crampon is offset from its base, so that their centers define a straight line forming an acute angle with the base. In other words, the crampon extends obliquely with respect to its base, so that by changing the orientation of the crampon relative to its direction of movement in the ground, the intensity of the force is controlled. who opposes his move. Therefore, the invention also provides a versatile crampon, whose penetration properties and hooked into the ground can easily be adapted to the type of support desired by its user, the nature of the soil and weather conditions.
De façon avantageuse, les cavités du crampon forment des échancrures au niveau des bords du sommet afin de réduire sa surface et ainsi favoriser une meilleure pénétration du crampon dans le sol. Les cavités forment également des évidements au niveau de la face arrière du crampon, afin d'augmenter la surface de contact du crampon dans le sol. Plus exactement, chaque cavité comprend une première face opposée à la face avant du crampon et une seconde face formant un côté de la paroi intermédiaire. Les premières faces sont configurées pour s'opposer au déplacement vers l'arrière du crampon dans le sol. Les secondes faces sont configurées pour s'opposer à un déplacement latéral du crampon. Ainsi, la paroi intermédiaire permet de limiter le déplacement latéral du crampon dans le sol, afin d'offrir une sensation d'accroché plus précise et plus sûre à son utilisateur. De préférence, la paroi intermédiaire est agencée de manière à délimiter des cavités symétriques, afin d'éviter que le sol exerce des forces différentes de résistance au déplacement du crampon au niveau de chaque cavité, susceptibles d'engendrer un mouvement de pivotement du crampon. Advantageously, the cavities of the crampon form indentations at the edges of the crown in order to reduce its area and thus promote better penetration of the crampon into the ground. The cavities also form recesses at the rear face of the crampon, in order to increase the contact surface of the crampon in the ground. More exactly, each cavity comprises a first face opposite to the front face of the crampon and a second face forming one side of the intermediate wall. The first faces are configured to oppose rearward movement of the crampon into the ground. The second faces are configured to oppose lateral movement of the crampon. Thus, the intermediate wall makes it possible to limit the lateral displacement of the crampon in the ground, in order to offer a feeling of hooking that is more precise and safer for its user. Preferably, the intermediate wall is arranged so as to define symmetrical cavities, to prevent the soil exerts different forces of resistance to the displacement of the stud at each cavity, likely to cause a pivoting movement of the crampon.
Selon un mode de réalisation préféré, la paroi intermédiaire s'étend selon une direction radiale au crampon, afin que les secondes faces de la paroi intermédiaire soient les plus larges possible pour prévenir un glissement latéral du crampon dans le sol. Ce mode de réalisation permet donc de conserver les propriétés de pénétration et d'ancrage du crampon dans le sol lors de son utilisation, en assurant une évacuation régulière et naturelle de la terre présente dans les cavités à chaque fois que le crampon ressort du sol. According to a preferred embodiment, the intermediate wall extends in a radial direction to the crampon, so that the second faces of the intermediate wall are as wide as possible to prevent lateral sliding of the crampon in the ground. This embodiment thus makes it possible to retain the penetration and anchoring properties of the crampon in the ground during its use, by ensuring a regular and natural evacuation of the earth present in the cavities each time the crampon comes out of the ground.
Selon une autre caractéristique de l'invention, le centre du sommet et le centre de la base du crampon sont agencés de sorte à définir une droite formant un angle aigu avec la base. De préférence, la valeur de cet angle est inférieure à 8o° pour permettre une meilleure accroche du crampon dans le sol. La valeur de cet angle est de préférence supérieure à 6o° afin de limiter les contraintes sur la chaussure, exercées par le crampon lors de sa pénétration dans le sol. En effet, ces contraintes sont susceptibles de causer une sensation d'inconfort, voire de blesser son utilisateur, lorsqu'elles sont trop intenses. Selon un mode de réalisation préféré, la valeur de cet angle est de l'ordre de 750, cette valeur correspondant à un compromis entre une bonne accroche et une utilisation confortable du crampon. Bien entendu, ces valeurs sont susceptibles de varier en fonction de la nature du terrain, de la position et/ou de l'orientation du crampon par rapport à la chaussure. According to another characteristic of the invention, the center of the crown and the center of the crampon base are arranged so as to define a line forming an acute angle with the base. Preferably, the value of this angle is less than 80 ° to allow better grip of the crampon in the ground. The value of this angle is preferably greater than 60 ° in order to limit the stresses on the shoe, exerted by the crampon during its penetration into the ground. Indeed, these constraints are likely to cause a feeling of discomfort or injury to the user, when they are too intense. According to a preferred embodiment, the value of this angle is of the order of 75 0 , this value corresponding to a compromise between good grip and comfortable use of the crampon. Of course, these values are likely to vary depending on the nature of the ground, the position and / or the orientation of the crampon relative to the shoe.
Selon un autre mode de réalisation de l'invention, l'angle d'inclinaison de la face arrière est supérieur à l'angle d'inclinaison de la face avant par rapport à la base du crampon. Autrement dit, le sommet du crampon se projette vers l'avant du crampon de manière à favoriser un plus grand volume des cavités. Selon un mode de réalisation préféré, le contour de la base du crampon est de forme ovale ou bien circulaire. According to another embodiment of the invention, the angle of inclination of the rear face is greater than the angle of inclination of the front face relative to the base of the crampon. In other words, the top of the crampon projects towards the front of the crampon so as to favor a larger volume of the cavities. According to a preferred embodiment, the outline of the crampon base is oval or circular.
Selon une autre caractéristique de l'invention, le sommet du crampon a une surface inférieure à 60% à la surface de sa base, de préférence la surface du sommet est comprise entre 50% et 20% de la surface de sa base. According to another characteristic of the invention, the top of the crampon has a surface less than 60% at the surface of its base, preferably the surface of the top is between 50% and 20% of the surface of its base.
Selon une autre caractéristique de l'invention, au moins une cavité s'étend sur au moins 50% de la distance séparant la base du sommet du crampon, de préférence sur au moins 80% de cette distance. Autrement dit, les cavités s'étendent sur une partie seulement de la hauteur du crampon de manière à ne pas modifier la forme du contour de sa base. En d'autres termes, entre la base du crampon et les cavités, la paroi latérale est continue tout autour du crampon. Par le terme « hauteur », on entend ici la distance séparant la base du sommet du crampon. According to another characteristic of the invention, at least one cavity extends over at least 50% of the distance separating the base from the top of the crampon, preferably at least 80% of this distance. In other words, the cavities extend over only a portion of the height of the crampon so as not to modify the shape of the outline of its base. In other words, between the base of the crampon and the cavities, the side wall is continuous all around the crampon. By the term "height" is meant here the distance separating the base of the crampon vertex.
De préférence, la base et le sommet sont de surfaces planes ou sensiblement planes et parallèles ou sensiblement parallèles entre elles. Selon un mode de réalisation préféré, la surface du sommet est légèrement convexe afin de favoriser la pénétration du crampon dans le sol. Preferably, the base and the apex are of plane or substantially plane surfaces and parallel or substantially parallel to each other. According to a preferred embodiment, the surface of the top is slightly convex in order to promote the penetration of the crampon into the ground.
Selon une autre caractéristique de l'invention, la paroi intermédiaire est de forme concave au niveau de la face arrière du crampon, afin de faciliter la pénétration du crampon dans le sol. According to another characteristic of the invention, the intermediate wall is of concave shape at the rear face of the crampon, to facilitate the penetration of the crampon into the ground.
Selon une autre caractéristique de l'invention, au moins une cavité comprend une première face opposée à la face avant du crampon, de forme concave. La concavité de la première face favorise un meilleur accrochage du crampon dans le sol. À l'inverse, selon une autre caractéristique de l'invention, la face avant du crampon est de forme convexe, de préférence de surface lisse, pour favoriser sa pénétration dans le sol. According to another characteristic of the invention, at least one cavity comprises a first face opposite to the front face of the crampon, of concave shape. The concavity of the first face promotes a better grip of the crampon in the ground. Conversely, according to another characteristic of the invention, the front face of the crampon is of convex shape, preferably of smooth surface, to promote its penetration into the ground.
Selon une autre caractéristique de l'invention, le crampon comprend un moyen de fixation s'étendant depuis sa base, le moyen de fixation étant configuré pour permettre la fixation du crampon de façon réversible à une chaussure. Par le terme « réversible », on entend la possibilité pour un utilisateur de monter ou de démonter à volonté le crampon sur la chaussure. Selon un mode de réalisation préféré, le moyen de fixation comporte une tige filetée s'étendant perpendiculairement à la base du crampon. According to another characteristic of the invention, the crampon comprises a fixing means extending from its base, the fixing means being configured to allow the attachment of the crampon reversibly to a shoe. The term "reversible" means the possibility for a user to assemble or dismount at will the crampon on the shoe. According to a preferred embodiment, the fastening means comprises a threaded rod extending perpendicularly to the base of the crampon.
Selon une autre caractéristique de l'invention, le crampon comporte des échancrures et/ou d'autres cavités, de manière à alléger son poids. According to another characteristic of the invention, the crampon comprises indentations and / or other cavities, so as to lighten its weight.
Selon une autre caractéristique de l'invention, le crampon comporte au moins deux parois intermédiaires, chaque paroi intermédiaire séparant deux cavités ouvertes à la fois sur le sommet et la face arrière du crampon. Selon un mode de réalisation préféré, les parois intermédiaires sont parallèles entre elles. Selon un autre mode de réalisation préféré, les parois intermédiaires sont sécantes de sorte à former un angle inférieur à 6o°, de préférence compris entre io° et 20°. La présente invention porte également sur une chaussure comprenant au moins un crampon tel que défini ci-dessus. En particulier, l'invention vise à équiper des chaussures de sport utilisées par exemple dans le domaine du rugby, du foot, du golf ou autre. According to another characteristic of the invention, the crampon comprises at least two intermediate walls, each intermediate wall separating two cavities open on both the top and the rear face of the crampon. According to a preferred embodiment, the intermediate walls are parallel to each other. According to another preferred embodiment, the intermediate walls are intersecting so as to form an angle less than 60 °, preferably between 10 ° and 20 °. The present invention also relates to a shoe comprising at least one crampon as defined above. In particular, the invention aims to equip sports shoes used for example in the field of rugby, football, golf or other.
L'invention concerne aussi un kit de montage d'un crampon décrit ci- dessus, comportant : The invention also relates to a kit for mounting a crampon described above, comprising:
- un crampon selon l'invention comprenant une tige filetée s'étendant perpendiculairement à sa base ;  a spike according to the invention comprising a threaded rod extending perpendicularly to its base;
- une rondelle comprenant une ouverture en son centre, configurée pour permettre le passage de la tige filetée ;  - A washer comprising an opening in its center, configured to allow the passage of the threaded rod;
- un outil comportant un logement de forme complémentaire au sommet du crampon et un moyen de préhension configuré pour faciliter le pivotement du crampon selon l'axe de la tige filetée. De préférence, la rondelle est de nature élastique. Ainsi, lors du vissage du crampon sur une chaussure, la rondelle intercalée entre le crampon et la chaussure subit des forces de contraintes aptes à faire varier l'épaisseur de la rondelle. En fonction de l'écrasement de la rondelle entre le crampon et la chaussure, l'orientation du crampon peut être modifiée simplement et rapidement. Le kit de montage permet ainsi à un même crampon d'avoir de nombreuses positions différentes de montage sur une même chaussure. a tool comprising a housing of complementary shape at the top of the crampon and a gripping means configured to facilitate the pivoting of the crampon along the axis of the threaded rod. Preferably, the washer is of an elastic nature. Thus, when screwing the crampon on a shoe, the washer interposed between the crampon and the shoe undergoes stress forces capable of varying the thickness of the washer. Depending on the crushing of the washer between the crampon and the shoe, the orientation of the crampon can be changed simply and quickly. The mounting kit thus allows the same crampon to have many different mounting positions on the same shoe.

Manière de réaliser l'invention Way of realizing the invention
Pour rappel, l'invention propose un crampon pour chaussure, s'adaptant aisément à une chaussure en fonction des appuis recherchés par son utilisateur, du sol et des conditions climatiques. Les figures l à 3 illustrent un exemple non limitatif de réalisation d'un crampon 100 selon l'invention. Selon le présent exemple, le crampon comprend une paroi latérale 110 s'étendant entre une base 120 et un sommet 130. Plus précisément, la paroi latérale 110 délimite le contour du crampon entre sa base et son sommet. As a reminder, the invention provides a shoe cleat, easily adapting to a shoe according to the supports sought by its user, soil and weather conditions. Figures 1 to 3 illustrate a non-limiting embodiment of a crampon 100 according to the invention. According to the present example, the crampon comprises a side wall 110 extending between a base 120 and a top 130. More specifically, the side wall 110 defines the outline of the crampon between its base and its top.
La base 120 du crampon est de forme circulaire et de surface plane. Le diamètre de la base est compris entre 10mm et 100mm, de préférence compris entre 10mm et 50mm. Selon le présent exemple, le diamètre de la base 120 est de l'ordre de 20mm. Depuis le centre A de la base s'étend, perpendiculairement à sa surface, une tige filetée 140. La longueur, le diamètre ainsi que le pas du filetage de la tige sont configurés pour permettre à un utilisateur de visser la tige filetée dans une semelle de chaussure. Selon le présent exemple, la tige filetée se caractérise par un filetage de type M5XO.8 et une longueur de l'ordre de 6mm. The base 120 of the crampon is circular in shape and flat surface. The diameter of the base is between 10mm and 100mm, preferably between 10mm and 50mm. According to the present example, the diameter of the base 120 is of the order of 20 mm. From the center A of the base extends perpendicular to its surface, a threaded rod 140. The length, the diameter and the pitch of the thread of the rod are configured to allow a user to screw the threaded rod in a sole shoe. According to the present example, the threaded rod is characterized by a thread type M5XO.8 and a length of the order of 6mm.
Le sommet 130 du crampon est également de surface plane et parallèle ou sensiblement parallèle à la base 120. La hauteur du crampon, définie comme la distance séparant sa base de son sommet, est comprise entre 5mm et 30mm, de préférence comprise entre 10mm et 21mm. Selon le présent exemple, la hauteur du crampon est de l'ordre de 18 mm. Le centre B du sommet est décalé par rapport à l'axe de la tige filetée 140, de sorte que les centres A et B définissent une droite (AB) formant un angle aigu a avec la base 120. La valeur de cet angle est comprise entre 500 et 850, il est de préférence compris entre 6o° et 900 pour les raisons mentionnées ci-dessus. Selon le présent exemple, la valeur de l'angle a est de l'ordre de 75 °. Il est à noter que la face arrière est plus inclinée que la face avant par rapport à la base du crampon. The top 130 of the crampon is also of flat surface and parallel or substantially parallel to the base 120. The height of the crampon, defined as the distance separating its base from its top, is between 5mm and 30mm, preferably between 10mm and 21mm . According to the present example, the height of the crampon is of the order of 18 mm. The center B of the apex is offset with respect to the axis of the threaded rod 140, so that the centers A and B define a straight line (AB) forming an acute angle a with the base 120. The value of this angle is included between 50 0 and 85 0 , it is preferably between 60 and 90 0 for the reasons mentioned above. According to the present example, the value of the angle a is of the order of 75 °. It should be noted that the rear face is more inclined than the front face relative to the base of the crampon.
Comme illustré à la figure 1, la paroi latérale 110 comprend une face avant 150 et une face arrière 160. La face arrière 160 est opposée à la face avant 150 et lesdites faces sont jointes sur leur côté de manière à former une paroi latérale entourant la base 120 du crampon 100. Selon le présent exemple, la face avant 150 du crampon s'étend sur 1800 autour de la base, la face arrière 150 s'étendant sur les 1800 complémentaires. As illustrated in Figure 1, the side wall 110 comprises a front face 150 and a rear face 160. The rear face 160 is opposite the front face 150 and said faces are joined on their side so as to form a side wall surrounding the base 120 of the crampon 100. According to the present example, the front face 150 of the crampon extends over 180 0 around the base, the rear face 150 extending over the 180 0 complementary.
La face arrière 160 comporte deux cavités 170 distinctes telles que représentées à la figure 2. Chaque cavité est ouverte à la fois sur la face arrière 160 et sur le sommet 130 du crampon. Autrement dit, les cavités forment des renfoncements au niveau de la face arrière 160 et du sommet 130 du crampon. Il est à noter que les cavités 170 peuvent éventuellement s'étendre sur une partie de la face avant 150, selon un mode de réalisation alternatif non représenté. The rear face 160 has two distinct cavities 170 as shown in FIG. 2. Each cavity is open both on the rear face 160 and on the top 130 of the crampon. In other words, the cavities form recesses at the rear face 160 and the top 130 of the crampon. It should be noted that the cavities 170 may possibly extend over a portion of the front face 150, according to an alternative embodiment not shown.
Comme illustré à la figure 3, les cavités 170 forment ainsi une échancrure 132 au niveau du sommet 130. Autrement dit, les cavités 170 débouchent sur le sommet 130 de manière à modifier la forme de son contour. As illustrated in Figure 3, the cavities 170 and form a notch 132 at the top 130. In other words, the cavities 170 open on the top 130 so as to change the shape of its outline.
Les cavités 170 sont symétriques par rapport à une paroi intermédiaire 180 de manière à ce que le contour du sommet 130 s'apparente à la forme d'un « T ». La paroi intermédiaire 180 s'étend selon une direction allant de l'avant vers l'arrière du crampon et est délimitée par une partie de la face arrière 160 du crampon visible sur les figures 2 et 3. The cavities 170 are symmetrical with respect to an intermediate wall 180 so that the outline of the vertex 130 is similar to the shape of a "T". The intermediate wall 180 extends in a direction from the front to the rear of the crampon and is delimited by a portion of the rear face 160 of the crampon visible in Figures 2 and 3.
De préférence, la surface du sommet 130 est comprise entre 20% et 60% de la surface de la base. Selon le présent exemple, la surface du sommet correspond à 30% de la surface de la base 120. Plus précisément, chaque cavité 170 est délimitée par une première face 172 opposée à la face avant 150 ou à l'avant du crampon 100, une deuxième face 174 correspondant à un côté de la paroi intermédiaire 180 et une troisième face 176 en regard de la base 120. La première face 172 et la deuxième face 174 sont de forme concave afin de favoriser une meilleure attache du crampon dans le sol. La troisième face 176 est parallèle ou sensiblement parallèle à la base 120 et est située à une distance du sommet 130 comprise entre 10% et 90% de la hauteur du crampon, de préférence entre 60% et 80%. Par le terme « hauteur », on entend ici la distance séparant la base du sommet du crampon. Selon le présent exemple, la troisième face 176 est située à une distance du sommet 130 de l'ordre de 75% de la hauteur du crampon. De ce fait, les cavités 170 ne s'étendent pas jusqu'à la base 120 du crampon. Preferably, the top surface 130 is between 20% and 60% of the base area. According to the present example, the surface of the apex corresponds to 30% of the surface of the base 120. More specifically, each cavity 170 is delimited by a first face 172 opposite to the front face 150 or to the front of the crampon 100, a second face 174 corresponding to one side of the intermediate wall 180 and a third face 176 facing the base 120. The first face 172 and the second face 174 are concave in order to promote better attachment of the crampon in the ground. The third face 176 is parallel or substantially parallel to the base 120 and is located at a distance from the top 130 of between 10% and 90% of the height of the crampon, preferably between 60% and 80%. By the term "height" is meant here the distance separating the base of the crampon vertex. According to the present for example, the third face 176 is located at a distance from the top 130 of the order of 75% of the height of the crampon. As a result, the cavities 170 do not extend to the base 120 of the crampon.
La deuxième face 174 s'étend selon une direction radiale ou sensiblement radiale à l'axe de la tige filetée 140. L'intersection entre la deuxième face 174 et la troisième face 176 forme une arrête 175 indexée sur la figure 3, dont la longueur est comprise entre 20% et 80% du diamètre de la base 120, de préférence entre 50% et 80%. Selon le présent exemple, la longueur de l'arrête 175 correspond à 50% du diamètre de la base 120. De même, l'intersection entre la première face 172 et la troisième face 176 forme une arrête 173 indexée à la figure 2, dont la longueur est comprise entre 20% et 80% du diamètre de la base 120, de préférence entre 20% et 50%. Selon le présent exemple, la longueur de l'arrête 173 correspond à 30% du diamètre de la base 120. The second face 174 extends in a direction radial or substantially radial to the axis of the threaded rod 140. The intersection between the second face 174 and the third face 176 forms a stop 175 indexed in Figure 3, whose length is between 20% and 80% of the diameter of the base 120, preferably between 50% and 80%. According to the present example, the length of the stop 175 corresponds to 50% of the diameter of the base 120. Similarly, the intersection between the first face 172 and the third face 176 forms a stop 173 indexed in FIG. the length is between 20% and 80% of the diameter of the base 120, preferably between 20% and 50%. According to the present example, the length of the stop 173 corresponds to 30% of the diameter of the base 120.
En particulier, les arrêtes 173 et 175 se croisent selon un angle β compris entre 300 et 1200, de préférence compris entre 8o° et 1000. Selon le présent exemple, la valeur de l'angle β est de l'ordre de 900. Ainsi, les cavités 170 s'étendent sur une partie du périmètre du crampon 100. Chaque cavité 170 peut ainsi s'étendre entre 5% à 30% du pourtour du crampon 100. Selon le présent exemple, chaque cavité s'étend sur 20% du pourtour. Les cavités 170 sont séparées par la paroi intermédiaire 180 indexée sur la figure 3, délimitée par les deuxièmes faces 174 des cavités. L'épaisseur de la paroi intermédiaire, mesurée sur la face arrière 160 au niveau des deuxièmes faces 174 des cavités, correspond entre 1% et 30% du pourtour du crampon 100. Selon le présent exemple, l'épaisseur est de l'ordre de 5% du pourtour du crampon. Selon un mode de réalisation préféré, les deuxièmes faces 174 sont parallèles entre elles, afin que l'épaisseur de la paroi intermédiaire soit constante. À l'inverse, selon un autre mode de réalisation préféré, les deuxièmes faces 174 sont agencées de manière à converger au niveau de la face arrière 160. En d'autres termes, l'épaisseur de la paroi intermédiaire 180 peut varier selon une direction radiale à l'axe de la tige filetée 140. De préférence, l'épaisseur de la paroi intermédiaire 180 décroît à proximité de la face arrière 160 afin d'offrir un profil effilé, plus favorable à la pénétration du crampon dans le sol. In particular, the edges 173 and 175 intersect at an angle β between 30 0 and 120 0 , preferably between 80 ° and 100 0 . According to the present example, the value of the angle β is of the order of 90 ° . Thus, the cavities 170 extend over a part of the perimeter of the crampon 100. Each cavity 170 can thus extend between 5% and 30% of the periphery of the crampon 100. According to the present example, each cavity extends over 20%. around. The cavities 170 are separated by the intermediate wall 180 indexed in Figure 3, delimited by the second faces 174 of the cavities. The thickness of the intermediate wall, measured on the rear face 160 at the second faces 174 of the cavities, corresponds to between 1% and 30% of the periphery of the crampon 100. According to the present example, the thickness is of the order of 5% around the crampon. According to a preferred embodiment, the second faces 174 are parallel to each other, so that the thickness of the intermediate wall is constant. Conversely, according to another preferred embodiment, the second faces 174 are arranged to converge at the rear face 160. In other words, the thickness of the intermediate wall 180 may vary according to a direction radial to the axis of the threaded rod 140. Preferably, the thickness of the intermediate wall 180 decreases near the rear face 160 to provide a tapered profile, more favorable to the penetration of the crampon into the ground .
Il est à noter qu'il est envisageable de modifier une ou plusieurs valeurs mentionnées ci-dessus, dans les plages de valeurs indiquées, afin d'obtenir d'autres modes de réalisation d'un crampon selon l'invention. Autrement dit, une ou plusieurs valeurs mentionnées ci-dessus peuvent être changées indépendamment des autres. It should be noted that it is conceivable to modify one or more values mentioned above, within the indicated ranges of values, in order to obtain other embodiments of a crampon according to the invention. In other words, one or more values mentioned above can be changed independently of others.
Un crampon 100 décrit ci-dessus peut être réalisé à partir d'au moins un des matériaux suivants : étain, aluminium, titane, magnésium, chrome-cobalt et/ou un polymère synthétique. A crampon 100 described above can be made from at least one of the following materials: tin, aluminum, titanium, magnesium, chromium-cobalt and / or a synthetic polymer.
De préférence, un crampon 100 est fabriqué par une technique de moulage, d'injection ou par une technique d'impression en trois dimensions. Preferably, a crampon 100 is manufactured by a molding technique, injection or by a three-dimensional printing technique.
La présente invention porte aussi sur un kit de montage 200 illustré aux figures 4 à 6, d'un crampon 100 sur une semelle de chaussure. Le kit de montage comprend un outil 210 représenté aux figures 4 et 5. L'outil 210 comporte un moyen de préhension 220 et un logement 230 de forme complémentaire au sommet 130 du crampon 100. L'outil 210 est ainsi configuré pour permettre à un utilisateur d'engager et maintenir fermement une partie du crampon dans le logement 230, puis pivoter le crampon selon l'axe de sa tige fileté 140 à l'aide du moyen de préhension 220. L'outil 210 permet avantageusement à un utilisateur de visser la tige filetée 140 dans la semelle d'une chaussure, avec un couple de serrage plus important. The present invention also relates to a mounting kit 200 illustrated in Figures 4 to 6, a crampon 100 on a shoe sole. The mounting kit comprises a tool 210 shown in Figures 4 and 5. The tool 210 comprises a gripping means 220 and a housing 230 of complementary shape at the top 130 of the crampon 100. The tool 210 is thus configured to allow a user to engage and hold firmly a portion of the crampon in the housing 230, then rotate the clamp along the axis of its threaded rod 140 with the gripping means 220. The tool 210 advantageously allows a user to screw the threaded rod 140 in the sole of a shoe, with a greater torque.
Le kit de montage 200 comprend également une rondelle 240 comportant une ouverture en son centre. Comme illustré à la figure 6, l'ouverture est configurée pour permettre le passage de la tige filetée 140 à travers la rondelle. L'épaisseur de la rondelle 240, délimitée par ses faces latérales, est comprise entre 0,5 mm et 5mm, elle est de préférence de l'ordre de 0,8mm. La rondelle est élastique afin de permettre sa déformation lors du serrage du crampon contre une semelle. Ainsi, en fonction du serrage du crampon, celui-ci peut être orienté différemment vis-à-vis de la semelle. The mounting kit 200 also includes a washer 240 having an opening at its center. As illustrated in Figure 6, the opening is configured to allow the passage of the threaded rod 140 through the washer. The thickness of the washer 240 delimited by its lateral faces is between 0.5 mm and 5 mm, it is preferably of the order of 0.8 mm. The puck is elastic to allow its deformation when tightening the crampon against a sole. Thus, depending on the tightening of the crampon, it can be oriented differently vis-à-vis the sole.
La présente invention porte également sur une semelle 300, comprenant un ou plusieurs crampons tels que décrits ci-dessus. Les figures 7 et 8 illustrent une semelle 300 comprenant 6 crampons 100 montés à l'aide du kit de montage 200. Selon un premier exemple illustré à la figure 7, la semelle comprend des logements identiques configurés pour accueillir : deux crampons 310 au niveau de l'avant 302, deux crampons 320 sur les côtés 304 et deux crampons 330 au niveau de l'arrière 306. Les logements sont taraudés de façon identique, de sorte à être compatibles avec le pas de vis de la tige filetée 180 d'un crampon 100. Dans chaque logement est vissée la tige filetée 180 d'un crampon 100 à l'aide de l'outil 210. Il est interposé une rondelle 240 entre chaque crampon et la semelle. Les crampons 310 sont vissés selon un premier couple de serrage de sorte à diminuer l'épaisseur de leur rondelle jusqu'à ce que leur face arrière soit orientée vers l'arrière de la semelle 300. Autrement dit, les rondelles sont comprimées entre les crampons 310 et la semelle 300 de manière à ce que l'axe (VR) passant par la face avant 150 et la paroi intermédiaire 180 d'un crampon 310, soit parallèle à la direction longitudinale (SS') de la semelle. Les crampons 320 sont vissés selon un deuxième couple de serrage de sorte à diminuer l'épaisseur de leur rondelle jusqu'à ce que leur face avant soit orientée vers l'extérieur de la semelle. Autrement dit, les rondelles sont comprimées entre les crampons 320 et la semelle 300 de manière à ce que l'axe (VR) passant par la face avant 150 et la paroi intermédiaire 180 d'un crampon 310, soit perpendiculaire à la direction longitudinale (SS') de la semelle. Les crampons 330 sont vissés selon un troisième couple de serrage de sorte à diminuer l'épaisseur de leur rondelle jusqu'à ce que leur face arrière soit orientée vers l'avant de la semelle. Autrement dit, les rondelles sont comprimées entre les crampons 320 et la semelle 300 de manière à ce que l'axe (VR) passant par la face avant 150 et la paroi intermédiaire 180 d'un crampon 310, soit parallèle à la direction longitudinale (SS') de la semelle. Ainsi, les faces arrière 160 des crampons 310 sont orientées de sorte à assurer une meilleure accroche de la semelle lorsque son utilisateur se déplace vers l'avant. À l'inverse, les crampons 330 situés à l'arrière de la semelle ont leur face arrière 160 orientée vers l'avant de la semelle, afin de permettre à l'utilisateur de la semelle de s'arrêter rapidement. Les faces arrière 160 des crampons 320 sont orientées vers l'intérieur de la semelle afin d'offrir de meilleurs appuis latéraux. The present invention also relates to a soleplate 300 comprising one or more studs as described above. Figures 7 and 8 illustrate a sole 300 comprising 6 studs 100 mounted using the mounting kit 200. In a first example shown in Figure 7, the sole comprises identical housings configured to accommodate: two spikes 310 at the level of the front 302, two studs 320 on the sides 304 and two studs 330 at the rear 306. The housings are threaded identically, so as to be compatible with the thread of the threaded rod 180 of a crampon 100. In each housing is screwed the threaded rod 180 of a crampon 100 with the tool 210. It is interposed a washer 240 between each crampon and the sole. The crampons 310 are screwed in a first tightening torque so as to reduce the thickness of their washer until their rear face is oriented towards the rear of the sole 300. In other words, the washers are compressed between the crampons 310 and the soleplate 300 so that the axis (VR) passing through the front face 150 and the intermediate wall 180 of a crampon 310, is parallel to the longitudinal direction (SS ') of the sole. The crampons 320 are screwed in a second tightening torque so as to reduce the thickness of their washer until their front face is oriented towards the outside of the sole. In other words, the washers are compressed between the crampons 320 and the soleplate 300 so that the axis (VR) passing through the front face 150 and the intermediate wall 180 of a crampon 310, is perpendicular to the longitudinal direction ( SS ') of the sole. The crampons 330 are screwed in a third tightening torque so as to reduce the thickness of their washer until their rear face is oriented towards the front of the sole. In other words, the washers are compressed between the crampons 320 and the soleplate 300 so that the axis (VR) passing through the front face 150 and the intermediate wall 180 of a crampon 310, is parallel to the longitudinal direction ( SS ') of the sole. Thus, the rear faces 160 of studs 310 are oriented so as to ensure better grip of the sole when the user moves forward. Conversely, the crampons 330 located at the rear of the sole have their rear face 160 facing the front of the sole, to allow the user of the sole to stop quickly. The rear faces 160 of the crampons 320 are oriented towards the inside of the sole in order to provide better lateral support.
La figure 8 illustre un deuxième exemple d'utilisation des crampons 100 sur une semelle 300. Cet exemple diffère du précédent en ce que les faces arrières 160 des crampons 310 sont pivotés de 180° de sorte à être dirigées vers l'avant de la semelle. FIG. 8 illustrates a second example of use of the crampons 100 on a soleplate 300. This example differs from the previous one in that the rear faces 160 of the crampons 310 are pivoted by 180 ° so as to be directed towards the front of the soleplate. .
La figure 7 montre ainsi un exemple de montage de crampons 100 selon l'invention, sur une semelle destinée à un joueur offensif, de type trois quart dans une équipe de rugby, alors que la figure 8 illustre un montage de crampon pour un joueur défensif de type pilier, nécessitant de bonnes qualités d'accroché de l'avant de la semelle pour exercer des poussées efficaces dans des regroupements de jeu. FIG. 7 thus shows an exemplary mounting of crampons 100 according to the invention, on a sole intended for an offensive player, of type three quarter in a rugby team, while FIG. 8 illustrates a crampon assembly for a defensive player. pillar type, requiring good qualities of hanging from the front of the sole to exert effective thrusts in game groupings.
L'invention porte également sur une chaussure munie d'une semelle 300 comportant un ou plusieurs crampons 100. De préférence, la chaussure est une chaussure de sport qui peut être utilisée dans le domaine du foot, du rugby, du golf ou autre. The invention also relates to a shoe with a sole 300 having one or more crampons 100. Preferably, the shoe is a sports shoe that can be used in the field of football, rugby, golf or other.
En conclusion, l'invention propose un nouveau type de crampon 100 offrant une plus grande efficacité d'accroché, un meilleur confort d'utilisation et une plus grande adaptabilité. Plus précisément, l'invention permet aisément et facilement à un utilisateur de modifier l'orientation de chaque crampon par rapport à la semelle, sans faire appel à de nombreux outils, ce qui lui donne la possibilité d'adapter rapidement l'accroche de sa chaussure en fonction du sol et/ou de la façon de jouer de son utilisateur. In conclusion, the invention proposes a new type of crampon 100 offering greater hooking efficiency, better user comfort and greater adaptability. More specifically, the invention easily and easily allows a user to change the orientation of each spike relative to the sole, without using many tools, which gives him the ability to quickly adapt the grip of his footwear depending on the ground and / or how to play the user.
