Description

Semelle à cramponnage multidirectionnel pour chaussure à tige.Multidirectional studded sole for shoe with upper.
Domaine technique de l'inventionTechnical field of the invention
L'invention est relative à une semelle moulée pour chaussure à tige comprenant : - une surface d'accrochage extérieure à crampons,The invention relates to a molded sole for shoe with an upper comprising: - an external attachment surface with studs,
- une surface interne opposée de réception du pied, un axe médian d'appui de la semelle sur le sol, ayant un profil curviligne, notamment en forme de S, la partie avant de la semelle étant recourbée vers l'intérieur, tandis que le talon de la semelle est orienté vers l'extérieur, respectivement pour optimiser l'appui en pronation et en supination sur le sol.- an opposite internal surface for receiving the foot, a median axis of support of the sole on the ground, having a curvilinear profile, in particular in the shape of an S, the front part of the sole being curved inwards, while the heel of the sole is oriented outward, respectively to optimize support in pronation and supination on the ground.
Etat de la techniqueState of the art
Le document EP-A-560698 décrit une chaussure de sport dont la partie avant de la semelle présente un certain degré de mobilité par rapport à la partie arrière, grâce à un élément de rigidification autorisant un léger mouvement de pivotement autour d'un axe vertical. La semelle comporte un axe médian d'appui sur le sol, ayant un profil curviligne, notamment en forme de S.Document EP-A-560698 describes a sports shoe whose front part of the sole has a certain degree of mobility relative to the rear part, thanks to a stiffening element allowing a slight pivoting movement around a vertical axis . The sole has a central axis of support on the ground, having a curvilinear profile, in particular in the shape of an S.
La venue en engagement de la surface d'accrochage de la semelle sur le sol s'effectue pour la plupart des individus de l'arrière vers l'avant. Le phénomène de supination du pied sollicite l'appui au niveau de la partie extérieure du talon, et l'appui en pronation intervient à la partie avant intérieure située sous le gros orteil de l'individu. L'usure d'une semelle classique est particulièrement prématurée à ces deux endroits, au détriment de la durée de vie de la paire de chaussures. L'absence de crampons débordants sur la superficie de la semelle est d'autre part préjudiciable à la stabilité et au confort sur des terrains en dévers. Objet de l'inventionThe coming into engagement of the attachment surface of the sole on the ground takes place for most individuals from back to front. The phenomenon of supination of the foot requests support at the level of the external part of the heel, and the support in pronation intervenes at the interior front part located under the big toe of the individual. The wear of a conventional sole is particularly premature in these two places, to the detriment of the life of the pair of shoes. The absence of protruding studs on the surface of the sole is also detrimental to stability and comfort on slopes. Subject of the invention
Un premier objet de l'invention consiste à réaliser une semelle à cramponnage multidirectionnel permettant d'améliorer la stabilité, le confort et l'accrochage de la chaussure.A first object of the invention consists in making a multidirectional lug sole making it possible to improve the stability, comfort and attachment of the shoe.
Un deuxième objet de l'invention consiste à réaliser une semelle moulée à crampons ayant une usure très réduite.A second object of the invention consists in making a molded studded sole having very reduced wear.
La semelle selon l'invention est caractérisée en ce que :The sole according to the invention is characterized in that:
- la face frontale de la partie avant de la semelle comprend une première série de crampons s'étendant le long d'une première courbe sensiblement perpendiculaire à l'axe, et ayant un rayon de courbure supérieur à celui R1 de la surface interne conjuguée de l'avant de la semelle,the front face of the front part of the sole comprises a first series of spikes extending along a first curve substantially perpendicular to the axis, and having a radius of curvature greater than that R1 of the conjugate internal surface of the front of the sole,
- la face arrière du talon comporte une deuxième série de crampons échelonnés le long d'une deuxième courbe sensiblement perpendiculaire à l'axe, et ayant un rayon de courbure supérieure à celui R2 de la surface interne conjuguée du talon.- The rear face of the heel comprises a second series of studs staggered along a second curve substantially perpendicular to the axis, and having a radius of curvature greater than that R2 of the internal conjugate surface of the heel.
La présence de crampons débordants sur la majorité de la périphérie de la semelle permet d'obtenir une excellente stabilité, et un accrochage optimum en dévers.The presence of protruding studs on the majority of the periphery of the sole provides excellent stability and optimum hooking on slopes.
Selon une caractéristique de l'invention, la répartition des crampons sur la surface d'accrochage extérieure suit le déroulement curviligne du pied le long de l'axe médian d'appui de la semelle.According to a characteristic of the invention, the distribution of the studs on the external attachment surface follows the curvilinear course of the foot along the median axis of support of the sole.
Selon un mode de réalisation préférentiel, la face latérale interne de la semelle comporte à l'avant une partie convexe garnie de crampons, et à l'arrière une partie concave dépourvue de crampons.According to a preferred embodiment, the internal lateral face of the sole comprises at the front a convex part furnished with crampons, and at the rear a concave part devoid of crampons.
La semelle moulée selon l'invention peut être monobloc, ou être réalisée en deux parties élémentaires réunies l'une à l'autre par des moyens de fixation. 3 Description sommaire des dessinsThe molded sole according to the invention can be in one piece, or be made in two elementary parts joined to one another by fixing means. 3 Brief description of the drawings

Description d'un mode de réalisation préférentielDescription of a preferred embodiment
Sur les figures 1 à 3, une chaussure 10 comporte une tige 12 montée sur une semelle 14 moulée à crampons 16. La semelle 14 est subdivisée en un premier élément de semelle 14A antérieur, et un deuxième élément de 4 semelle 14B postérieur, constituant deux pièces avant et arrière distinctes obtenues par moulage d'une matière élastomère ou à base de caoutchouc.In FIGS. 1 to 3, a shoe 10 comprises a upper 12 mounted on a sole 14 molded with studs 16. The sole 14 is subdivided into a first anterior sole element 14A, and a second element of 4 rear 14B sole, constituting two separate front and rear parts obtained by molding an elastomeric or rubber-based material.
Une bavette 18 convexe est agencée à l'avant du premier élément de semelle 14A en remontant sur la face supérieure de la tige 12. Les crampons 16 sont formés par des plots venant de moulage avec les éléments de semelle, et répartis sur la majorité de la surface inférieure entre la bavette 18 et la face de liaison 20.A convex flap 18 is arranged at the front of the first sole element 14A going up on the upper face of the rod 12. The studs 16 are formed by studs coming from molding with the sole elements, and distributed over the majority of the lower surface between the flap 18 and the connecting face 20.
Le deuxième élément de semelle 14B postérieur comprend un col 22 de maintien remontant sur l'arrière de la tige 12. Toute la surface inférieure du deuxième élément de semelle 14B est équipée de crampons 16, sauf la face de liaison 24 disposée dans la zone centrale en regard de l'autre face de liaison 20 adjacente.The second rear sole element 14B comprises a collar 22 for holding up the rear of the upper 12. The entire lower surface of the second sole element 14B is fitted with studs 16, except the connecting face 24 disposed in the central zone opposite the other adjacent connecting face 20.
En fonction de la pointure souhaitée, on ajuste dans la zone centrale le décalage e2 longitudinal entre les deux éléments de semelle 14A, 14B, et on enfourche par le bas l'organe de recouvrement 26 pour recouvrir ledit décalage e2.Depending on the desired size, the longitudinal offset e2 between the two sole elements 14A, 14B is adjusted in the central zone and the covering member 26 is straddled to cover said offset e2.
L'organe de recouvrement 26 peut être constitué par une bande de maintien souple ou semi-flexible, ayant une résistance mécanique élevée, et une bonne résistance à l'abrasion. Cette bande peut être assemblée par collage ou vulcanisation aux faces de liaison 20, 24, et est réalisée en un matériau ayant des composants compatibles avec le matériau de la semelle 14. Des crampons 27 d'accrochage supplémentaires peuvent être ménagés sur la face inférieure, et sur les faces latérales opposées de l'organe de recouvrement 26.The covering member 26 can be constituted by a flexible or semi-flexible retaining strip, having a high mechanical resistance, and a good resistance to abrasion. This strip can be assembled by bonding or vulcanization to the connecting faces 20, 24, and is made of a material having components compatible with the material of the sole 14. Additional attachment studs 27 can be provided on the underside, and on the opposite lateral faces of the covering member 26.
La bande peut également être conformée selon un collier en plastique interchangeable en fonction de la rigidité mécanique souhaitée.The strip can also be shaped according to an interchangeable plastic collar depending on the desired mechanical rigidity.
L'organe de recouvrement 26 peut également être relié à la tige 12 par des moyens de coutures. 5 Sur la figure 4, le démoulage des deux éléments de semelle 14A, 14B s'opère selon deux directions F1 , F2 obliques différentes par rapport à la surface d'appui de la semelle 14 sur le sol. Les deux directions F1 , F2 forment entre elles un angle obtu prédéterminé en fonction de l'orientation des crampons 16 faisant saillie des deux éléments 14A, 14B. Une paire de moules de dimensions réduites est nécessaire pour la fabrication des deux éléments de semelle 14A, 14B, et il est possible de fabriquer des semelles de pointures différentes, telles qu'il en ressort des figures 5 à 7.The covering member 26 can also be connected to the rod 12 by stitching means. 5 In Figure 4, the release of the two sole elements 14A, 14B takes place in two directions F1, F2 different oblique to the bearing surface of the sole 14 on the ground. The two directions F1, F2 form between them a predetermined obtuse angle as a function of the orientation of the studs 16 projecting from the two elements 14A, 14B. A pair of reduced-size molds is necessary for the manufacture of the two sole elements 14A, 14B, and it is possible to manufacture soles of different sizes, as shown in FIGS. 5 to 7.
Sur la figure 5, la semelle 14 correspond à une pointure P1 minimum, et les faces de liaison 20, 22 des deux éléments de semelle 14A, 14B se trouvent sensiblement en aboutement le long de la direction longitudinale. L'organe de recouvrement 26 est séparé du premier crampon de l'élément de semelle 14A par une distance d1 , et de celui de l'autre élément de semelle 14B par une distance d2.In FIG. 5, the sole 14 corresponds to a minimum size P1, and the connecting faces 20, 22 of the two sole elements 14A, 14B are located substantially in abutment along the longitudinal direction. The covering member 26 is separated from the first stud of the sole element 14A by a distance d1, and from that of the other sole element 14B by a distance d2.
Pour obtenir une semelle 14 d'une pointure P2 supérieure à celle P1 , il suffit d'écarter en sens opposés les deux éléments de semelle 14A, 14B jusqu'à un décalage e2 longitudinal prédéterminé (figure 6). Le même organe de recouvrement 26 de longueur 11 est utilisé dans les semelles des figures 5 et 6, mais les distances d3 et d4 dans la figure 6 sont respectivement supérieures à celles d1 et d2 de la figure 5.To obtain a sole 14 with a size P2 greater than that P1, it suffices to separate the two sole elements 14A, 14B in opposite directions until a predetermined longitudinal offset e2 (FIG. 6). The same covering member 26 of length 11 is used in the soles of FIGS. 5 and 6, but the distances d3 and d4 in FIG. 6 are respectively greater than those d1 and d2 of FIG. 5.
Dans la figure 7, la semelle 14 correspond à la pointure P2 et au décalage e2 longitudinal de celle de la figure 6, mais avec un organe de recouvrement 26 de longueur 12 supérieure à celle 11 des figures 5 et 6. Dans ce cas, les distances d1 et d2 sont identiques à celles utilisées pour la semelle de pointure P1 de la figure 5.In FIG. 7, the sole 14 corresponds to the size P2 and to the longitudinal offset e2 from that of FIG. 6, but with a covering member 26 of length 12 greater than that 11 of FIGS. 5 and 6. In this case, the distances d1 and d2 are identical to those used for the sole of size P1 in FIG. 5.
Les éléments de semelle 14A, 14B sont standards pour plusieurs pointures de chaussures, et un seul jeu de moules est suffisant pour la fabrication des semelles d'une partie de la gamme de chaussures, à tige 12 basse ou montante. 6 Sur la figure 8, le profil inférieur du premier élément de semelle 14A et du deuxième élément de semelle 14B suit des courbes C3 et C4 représentatives de l'enroulement naturel du pied pendant la foulée. La longueur B du deuxième élément de semelle 14B est supérieure aux deux tiers de la longueur A du premier élément de semelle 14A. Un tel dimensionnement de la semelle 14 tient compte de la répartition des charges, étant donné que 55% du poids est transmis à la chaussure dans l'axe tibia-péroné.The sole elements 14A, 14B are standard for several shoe sizes, and a single set of molds is sufficient for the manufacture of the soles of a part of the range of shoes, with a low or rising upper. 6 In FIG. 8, the lower profile of the first sole element 14A and of the second sole element 14B follows curves C3 and C4 representative of the natural winding of the foot during the stride. The length B of the second sole element 14B is greater than two thirds of the length A of the first sole element 14A. Such a dimensioning of the sole 14 takes account of the distribution of the loads, given that 55% of the weight is transmitted to the shoe in the tibia-fibula axis.
Sur les figures 8A et 8B, certains au moins des crampons 16 situés sous la surface inférieure du premier élément de semelle 14A sont conformés selon des plots 30 ayant chacun une arête postérieure 32 droite, sensiblement perpendiculaire à la face de liaison 20, et une arête antérieure 34 oblique. Inversement, le plot 36 de certains crampons 16 du deuxième élément de semelle 14B est doté d'une arête postérieure 38 oblique, et d'une arête antérieure 40 droite. Chaque plot 30, 36 comporte avantageusement une empreinte d'accrochage 42, 44 ménagée sous la face d'appui du crampon.In FIGS. 8A and 8B, at least some of the studs 16 situated under the lower surface of the first sole element 14A are shaped according to studs 30 each having a straight rear edge 32, substantially perpendicular to the connecting face 20, and an edge anterior 34 oblique. Conversely, the stud 36 of certain studs 16 of the second sole element 14B is provided with an oblique rear edge 38, and a straight front edge 40. Each stud 30, 36 advantageously comprises a fastening imprint 42, 44 formed under the bearing face of the crampon.
Sur la figure 9, les ailes latérales de l'organe de recouvrement 26 sont prolongées vers le haut pour former un collier 46 de retenue de l'avant pied. Le collier 46 entoure toute la périphérie de la partie antérieure de la tige 12, et comporte au sommet des moyens d'adaptation 48 d'un dispositif de serrage de la tige 12.In FIG. 9, the lateral wings of the covering member 26 are extended upward to form a collar 46 for retaining the forefoot. The collar 46 surrounds the entire periphery of the front part of the rod 12, and comprises at the top adaptation means 48 of a device for tightening the rod 12.
Sur la figure 10, le collier 46 est équipé en plus d'un bracelet 50 entourant horizontalement la tige 12 au niveau de la cheville pour constituer un dispositif de maintien en forme de Y. L'effet de cerclage horizontal et vertical de la tige 12 dû à la présence du collier 46 associé au bracelet 50 permet d'obtenir une immobilisation optimum du pied par rapport à la semelle 14.In FIG. 10, the collar 46 is additionally equipped with a bracelet 50 horizontally surrounding the rod 12 at the ankle to form a Y-shaped holding device. The effect of horizontal and vertical strapping of the rod 12 due to the presence of the collar 46 associated with the bracelet 50 makes it possible to obtain optimum immobilization of the foot relative to the sole 14.
En référence à la figure 11 , la partie avant du premier élément de semelle 14A d'une chaussure de gauche est légèrement recourbée vers l'intérieur, de manière à optimiser l'appui en pronation lors de la marche. Le talon du deuxième élément de semelle 14B est orienté vers l'extérieur pour bénéficier d'un appui stable avec le sol suite à l'effet de supination du pied. Le profil de la chaussure suit l'axe 52 médian d'appui de la semelle 14 sur le sol, ledit axe 7 étant curviligne en forme de S. La première série de crampons 16 sur la face frontale du premier élément de semelle 14A s'étend le long d'une première courbe C1 sensiblement perpendiculaire à l'axe médian 52. D'une manière similaire, la deuxième série de crampons 16 sur la face arrière du deuxième élément de semelle 14B s'étend le long d'une deuxième courbe C2 perpendiculaire à l'axe médian 52. La répartition des crampons 16 sur la surface inférieure de la semelle 14 (figure 3) suit également le déroulement curviligne du pied lors d'une foulée. La face latérale interne de la semelle 14 comporte une partie convexe 54 garnie de crampons 16 au niveau du premier élément de semelle 14A, et une partie concave 56 dépourvue de crampons au niveau du deuxième élément de semelle 14B. Le rayon de courbure externe de la première courbe C1 des crampons avant est supérieur au rayon de courbure R1 interne de l'avant de la" semelle 14. Il en est de même du rayon de courbure externe de la deuxième courbe C2 des crampons arrière comparé à celui R2 du talon interne de la semelle 14. Une telle répartition des crampons 16 sur la surface externe de la semelle 14 permet d'obtenir une bonne stabilité d'accrochage et un confort optimum pendant la marche, ainsi qu'une résistance à l'abrasion accrue de cette partie de la semelle très sollicitée lors de l'impact du talon sur le sol. Le rayon de courbure externe des courbes C1 et C2 est d'autre part supérieur à la moitié de la longueur de la semelle 14.With reference to FIG. 11, the front part of the first sole element 14A of a shoe on the left is slightly curved inwards, so as to optimize the support in pronation when walking. The heel of the second sole element 14B is oriented towards the outside to benefit from stable support with the ground following the supine effect of the foot. The profile of the shoe follows the central axis 52 of support of the sole 14 on the ground, said axis 7 being curvilinear in the shape of an S. The first series of studs 16 on the front face of the first sole element 14A extends along a first curve C1 substantially perpendicular to the median axis 52. In a similar manner, the second series of spikes 16 on the rear face of the second sole element 14B extends along a second curve C2 perpendicular to the median axis 52. The distribution of the spikes 16 on the lower surface of the sole 14 (FIG. 3) also follows the curvilinear course of the foot during a stride. The internal lateral face of the sole 14 has a convex part 54 furnished with spikes 16 at the first sole element 14A, and a concave part 56 devoid of spikes at the second sole element 14B. The external radius of curvature of the first curve C1 of the front studs is greater than the internal radius of curvature R1 of the front of the " sole 14. The same is true of the external radius of curvature of the second curve C2 of the rear studs compared to that R2 of the internal heel of the sole 14. Such a distribution of the studs 16 on the external surface of the sole 14 makes it possible to obtain good grip stability and optimum comfort during walking, as well as resistance to wear. increased abrasion of this part of the sole, which is very stressed during the impact of the heel on the ground, and the radius of external curvature of the curves C1 and C2 is more than half the length of the sole 14.
La figure 12 est une vue identique de la figure 11 pour une semelle d'un pied droit. L'axe curviligne médian 52 est conformé dans ce cas selon un S renversé.Figure 12 is an identical view to Figure 11 for a sole of a right foot. The median curvilinear axis 52 is shaped in this case according to an inverted S.
Sur la figure 13, la présence des crampons 16 débordants sur les bords latéraux de la semelle 14 procure un effet d'accrochage multidirectionnel sur sols plats ou en dévers.In FIG. 13, the presence of the studs 16 projecting over the lateral edges of the sole 14 provides a multidirectional hooking effect on flat or sloping soils.
Certaines zones les plus sollicitées de la semelle 14 peuvent être mises visuellement en évidence, soit avec des colorations prédéterminées, soit avec des matériaux de compositions différentes. Some of the most stressed areas of the sole 14 can be visually highlighted, either with predetermined colors, or with materials of different compositions.
