Description

Article chaussant à flexibilité améliorée  Article of footwear with improved flexibility
L'invention concerne un article chaussant, notamment une chaussure de loisirs ou de sport, comprenant une semelle d'usure sur laquelle est associée une tige en formant un logement de réception du pied d'un utilisateur. The invention relates to an article of footwear, in particular a leisure or sports shoe, comprising an outsole on which is associated a rod forming a housing for receiving the foot of a user.
Lors d'activités de loisirs ou sportives telles que la marche ou la course à pied, le pratiquant souhaite bénéficier d'une paire de chaussures résistante et lui assurant un bon amorti lors des appuis au sol afin d'éviter les blessures et traumatismes dus à la répétition des chocs. During leisure or sports activities such as walking or running, the practitioner wants a pair of resistant shoes and ensuring good cushioning during ground support to prevent injuries and trauma due to the repetition of shocks.
A cet effet, les chaussures présentent classiquement une structure de semelle formée notamment d'une semelle d'usure et d'une semelle intermédiaire qui sont réalisées à partir respectivement d'un matériau durable relativement rigide garantissant la résistance à l'abrasion au sol et d'un matériau compressible avec une épaisseur suffisante pour atténuer l'impact des chocs. To this end, the shoes conventionally have a sole structure formed in particular of a sole and a midsole which are made respectively from a relatively rigid durable material guaranteeing resistance to abrasion on the ground and a compressible material with a thickness sufficient to mitigate the impact of shocks.
Toutefois l'augmentation des qualités d'amorti et de résistance d'une telle structure de semelle est obtenue au détriment de sa flexibilité longitudinale et/ou en torsion pourtant nécessaire pour accompagner les mouvements naturels du pied. However, the increase of the cushioning and resistance qualities of such a sole structure is achieved to the detriment of its longitudinal flexibility and / or torsion, however necessary to accompany the natural movements of the foot.
On connaît par exemple du document US-7 946 058 une chaussure dont la structure de semelle comprend une semelle intermédiaire et une semelle d'usure qui sont solidarisées entre elles par collage et sont réalisées respectivement à partir de mousse de polyuréthane pour l'amorti et de caoutchouc pour la résistance à l'abrasion. US Pat. No. 7,946,058 discloses a shoe whose sole structure comprises a midsole and an outsole which are joined together by gluing and are made respectively from polyurethane foam for cushioning and of rubber for abrasion resistance.
En particulier, la semelle intermédiaire selon ce document est équipée d'une pluralité de sillons transversaux et longitudinaux semi-circulaires dans chacun desquels s'étendent des nervures en forme de charnières qui sont réalisées dans l'épaisseur de la semelle d'usure afin d'améliorer la flexibilité de la chaussure lors des appuis au sol. Toutefois, cette solution ne donne pas entière satisfaction en ce que la fixation de la semelle intermédiaire sur la semelle d'usure contraint leur déformation conjointe lors de la flexion du pied, notamment en conditionnant l'allongement de la semelle d'usure à une compression de la semelle intermédiaire, ce qui limite l'amélioration de la flexibilité conférée par les sillons. In particular, the midsole according to this document is equipped with a plurality of semicircular transverse and longitudinal grooves in each of which hinge-shaped ribs are formed which are formed in the thickness of the outsole in order to improve the flexibility of the shoe during ground support. However, this solution is not entirely satisfactory in that the attachment of the midsole on the outsole constrains their joint deformation during bending of the foot, in particular by conditioning the elongation of the outsole to compression of the midsole, which limits the improvement of the flexibility conferred by the grooves.
L'invention vise à perfectionner l'art antérieur en proposant notamment un article chaussant dont la structure de semelle présente une flexibilité améliorée afin de garantir la liberté de mouvement du pied, tout en conservant des propriétés d'amorti et de résistance optimales. The invention aims to improve the prior art by providing in particular a footwear whose sole structure has improved flexibility to ensure the freedom of movement of the foot, while maintaining optimal cushioning and strength properties.
A cet effet, l'invention propose un article chaussant comprenant une semelle d'usure sur laquelle est associée une tige en formant un logement de réception du pied d'un utilisateur dans lequel une semelle intermédiaire est disposée, ladite semelle intermédiaire présentant une paroi inférieure qui est posée sur une paroi supérieure de ladite semelle d'usure, chacune desdites parois étant équipée d'un réseau respectivement de nervures pour l'une et de sillons pour l'autre, lesdits réseaux étant agencés pour être positionnés l'un dans l'autre en autorisant des mouvements relatifs entre les nervures et les sillons lors de la flexion conjointe des semelles intermédiaire et d'usure. For this purpose, the invention provides a footwear comprising a wear sole on which is associated a rod forming a receiving housing of the foot of a user in which a midsole is disposed, said midsole having a lower wall which is placed on an upper wall of said outsole, each of said walls being equipped with a network respectively of ribs for one and grooves for the other, said networks being arranged to be positioned one in the other allowing relative movements between the ribs and the grooves during the joint flexion of the midsoles and wear.
D'autres particularités et avantages de l'invention apparaîtront dans la description qui suit, faite en référence aux figures annexées, dans lesquelles : Other features and advantages of the invention will appear in the description which follows, made with reference to the appended figures, in which:
- la figure 1 est une représentation schématique en perspective éclatée d'un article chaussant selon un mode de réalisation de l'invention ;  - Figure 1 is a schematic perspective exploded view of an article of footwear according to one embodiment of the invention;
- les figures 2 sont des représentations schématiques en coupe longitudinale du montage de la semelle intermédiaire sur la semelle d'usure de l'article chaussant selon la figure 1 , montrant respectivement lesdites semelles en appui à plat (figure 2a) et en flexion conjointe sur une partie d'avant-pied (figure 2b) ; - la figure 3 est une représentation partielle du montage des figures 2, montrant une autre configuration de la flexion conjointe des semelles d'usure et intermédiaire. FIGS. 2 are diagrammatic representations in longitudinal section of the mounting of the midsole on the outsole of the article of footwear according to FIG. 1, respectively showing said soles resting flat (FIG. 2a) and in joint flexion on a forefoot part (Figure 2b); - Figure 3 is a partial representation of the assembly of Figures 2, showing another configuration of the joint bending of the wear soles and intermediate.
En relation avec ces figures, on décrit ci-dessous un article chaussant, telle une chaussure destinée à la marche quotidienne et/ou sportive, comprenant une tige 1 associée sur une semelle d'usure 2, par exemple par collage ou par surmoulage, de manière à former un logement interne 3 destiné à recevoir le pied d'un utilisateur. In connection with these figures, an article of footwear is described below, such as a shoe intended for daily and / or sportive walking, comprising a rod 1 associated on a outsole 2, for example by gluing or overmoulding, of to form an inner housing 3 for receiving the foot of a user.
De façon connue, la tige 1 comprend une ouverture supérieure 4 dans laquelle un utilisateur peut glisser son pied dans le logement de réception 3, ladite tige pouvant en outre être équipée d'un moyen de serrage du pied dans ledit logement, tel un lacet ou des sangles auto-agrippantes, afin notamment de favoriser la stabilité dudit pied lors de son déplacement. In known manner, the rod 1 comprises an upper opening 4 in which a user can slide his foot into the receiving housing 3, said rod may also be equipped with a foot clamping means in said housing, such as a lace or self-gripping straps, in particular to promote the stability of said foot during its movement.
La tige 1 peut être réalisée dans un matériau textile et/ou à base d'un matériau thermoplastique, par exemple par moulage par injection, ladite tige pouvant comprendre plusieurs couches de matériau associées entre elles et aux propriétés garantissant notamment la respirabilité, l'étanchéité et/ou l'isolation thermique de l'article chaussant. The rod 1 may be made of a textile material and / or based on a thermoplastic material, for example by injection molding, said rod may comprise several layers of material associated with each other and with the properties guaranteeing in particular the breathability, the tightness and / or the thermal insulation of the footwear.
En relation avec la figure 1 , la tige 1 présente des dimensions agencées pour recouvrir au moins partiellement le pied, notamment les parties supérieure et arrière du pied, ainsi qu'une partie de cheville de l'utilisateur, la semelle d'usure 2 s'étendant sous la plante dudit pied. In relation to FIG. 1, the shank 1 has dimensions arranged to at least partially cover the foot, in particular the upper and the rear parts of the foot, as well as an ankle part of the user, the outsole 2 s extending under the sole of said foot.
En particulier, la tige 1 est de type « sans fond », avec un bord inférieur 5 associé à un bord périphérique 6 de la semelle d'usure 2. Pour faciliter le montage de la tige 1 , le bord périphérique 6 comprend une portion supérieure 6a s'étendant verticalement en saillie de la semelle d'usure 2 et à l'extérieur de laquelle ladite tige peut être associée, son bord inférieur 5 étant disposé sur un rebord externe 7 entourant ladite portion. En variante, la semelle d'usure 2 peut être associée sur l'extérieur de la tige 1 , notamment par surmoulage d'un bord périphérique de ladite semelle autour de ladite tige. In particular, the rod 1 is of "bottomless" type, with a lower edge 5 associated with a peripheral edge 6 of the outsole 2. To facilitate the mounting of the rod 1, the peripheral edge 6 comprises an upper portion 6a extending vertically protruding from the outsole 2 and outside of which said rod can be associated, its lower edge 5 being disposed on an outer flange 7 surrounding said portion. Alternatively, the outsole 2 can be associated on the outside of the rod 1, in particular by overmolding a peripheral edge of said sole around said rod.
La semelle d'usure 2 comprend une paroi inférieure 8 destinée à être en contact avec le sol et agencée de manière avantageuse pour assurer l'adhérence de l'article chaussant au sol. A cet effet, la semelle d'usure 2 peut être réalisée en une seule pièce par moulage d'un matériau synthétique qui est résistant à l'usure et à l'abrasion, par exemple à base d'un élastomère, tel que du caoutchouc, ou à base de PVC ou de TPE. The outsole 2 comprises a bottom wall 8 intended to be in contact with the ground and advantageously arranged to ensure the adherence of the footwear to the ground. For this purpose, the outsole 2 can be made in one piece by molding a synthetic material that is resistant to wear and abrasion, for example based on an elastomer, such as rubber , or based on PVC or TPE.
Une semelle intermédiaire 9 est disposée dans le logement de réception 3 de manière à former une couche de matériau entre le pied de l'utilisateur et la semelle d'usure 2, ladite semelle intermédiaire présentant une paroi inférieure 10 qui est posée sur une paroi supérieure 1 1 de ladite semelle d'usure en la recouvrant. An intermediate sole 9 is disposed in the receiving housing 3 so as to form a layer of material between the user's foot and the outsole 2, said intermediate sole having a bottom wall 10 which is placed on an upper wall 1 1 of said outsole by covering it.
La semelle intermédiaire 9 est agencée notamment pour assurer une fonction d'amortissement des impacts sur le sol et le confort de l'utilisateur. Pour ce faire, la semelle intermédiaire 9 peut être réalisée en une seule pièce à partir d'un matériau amortissant et résilient tel qu'une mousse d'éthylène-acétate de vinyle (EVA) qui permet également de limiter le poids de l'article chaussant, et/ou une mousse de polyuréthane (PU) à cellules fermées qui présente une grande résistance à l'usage, notamment relativement au tassement en permettant de garantir la durabilité de ses propriétés amortissantes. The midsole 9 is arranged in particular to provide a damping function of the impacts on the ground and the comfort of the user. To do this, the intermediate sole 9 can be made in one piece from a damping and resilient material such as an ethylene-vinyl acetate foam (EVA) which also limits the weight of the article footwear, and / or closed-cell polyurethane (PU) foam which has a high resistance to use, particularly with regard to settlement, to ensure the durability of its damping properties.
En relation avec les figures 2, la semelle intermédiaire 9 présente une épaisseur agencée pour former un relief correspondant à la morphologie de la plante du pied de sorte que ladite semelle comprend une paroi supérieure 12 dont la géométrie anatomique optimise le confort de marche. In relation with FIGS. 2, the intermediate sole 9 has a thickness arranged to form a relief corresponding to the morphology of the sole of the foot so that said sole comprises an upper wall 12 whose anatomical geometry optimizes the walking comfort.
Une première de propreté peut être disposée dans le logement de réception 3 pour être interposée entre la plante du pied de l'utilisateur et la semelle intermédiaire 9. La première de propreté peut être disposée sur la paroi supérieure 12 de la semelle intermédiaire 9 de manière fixe ou réversible. En variante, une première de propreté peut être surmoulée sur la semelle intermédiaire 9. La première de propreté est agencée pour augmenter le confort de pied, en renforçant notamment une ou plusieurs propriétés particulières de la semelle intermédiaire 9, telles que l'amorti, l'absorption de l'humidité ou la réduction des frottements, ladite première de propreté pouvant être réalisée par exemple à partir de mousse polyuréthane alvéolée. A first clean can be arranged in the receiving housing 3 to be interposed between the soles of the user's foot and the intermediate sole 9. The insole can be arranged on the wall upper 12 of the midsole 9 in a fixed or reversible manner. Alternatively, a sockliner may be overmolded on the midsole 9. The sockliner is arranged to increase the foot comfort, including reinforcing one or more particular properties of the midsole 9, such as cushioning, lining. absorption of moisture or reduction of friction, said first cleanliness can be achieved for example from cellular polyurethane foam.
En outre, la semelle intermédiaire 9 et/ou la première de propreté peuvent présenter une dureté et/ou une densité localisées qui peuvent varier selon la zone de la plante du pied supportée, ladite semelle intermédiaire pouvant également comprendre des inserts agencés pour renforcer l'amorti de ladite semelle tel que de l'air encapsulé ou du gel. In addition, the midsole 9 and / or the sock may have a localized hardness and / or density which may vary depending on the area of the sole of the foot supported, said midsole may also include inserts arranged to strengthen the cushioning said sole such as encapsulated air or gel.
Afin notamment d'adapter l'article chaussant aux besoins de l'utilisateur, la semelle intermédiaire 9 peut être posée sur la semelle d'usure 2 de manière réversible, pouvant ainsi être remplacée par une semelle intermédiaire 9 aux caractéristiques similaires ou différentes en particulier en termes de capacité d'amortissement. In particular in order to adapt the footwear to the needs of the user, the intermediate sole 9 can be placed on the outsole 2 in a reversible manner, thus being able to be replaced by a midsole 9 with similar or different characteristics, in particular in terms of depreciation capacity.
Ainsi, l'utilisateur peut choisir une semelle intermédiaire 9 donnée qu'il lui suffit de glisser dans le logement 3 à travers l'ouverture supérieure 4 de la tige 1 afin d'adapter l'article chaussant à ses caractéristiques physiques et/ou physiologiques, notamment son poids et/ou son type de foulée. Thus, the user can choose a given midsole 9 that it suffices to slide in the housing 3 through the upper opening 4 of the rod 1 in order to adapt the footwear to its physical and / or physiological characteristics including weight and / or type of stride.
En particulier, le bord périphérique 6 de la semelle d'usure 2 peut être agencé pour former une cavité dans laquelle la semelle intermédiaire 9 est disposée pour optimiser son positionnement dans le logement de réception 3. De façon avantageuse, la semelle intermédiaire 9 et la cavité présentent une géométrie complémentaire afin que la semelle intermédiaire 9 soit en appui latéral contre la portion supérieure 6a du bord périphérique 6. Par ailleurs, la paroi supérieure 12 de la semelle intermédiaire 9 peut être alignée avec le haut de la portion supérieure 6a. In particular, the peripheral edge 6 of the outsole 2 may be arranged to form a cavity in which the intermediate sole 9 is arranged to optimize its positioning in the receiving housing 3. Advantageously, the midsole 9 and the cavity have a complementary geometry so that the midsole 9 is in lateral support against the upper portion 6a of the peripheral edge 6. Moreover, the upper wall 12 of the midsole 9 may be aligned with the top of the upper portion 6a.
En variante, la semelle intermédiaire 9 peut être fixée de façon périphérique à la semelle d'usure 2 et/ou à la tige 1 , en étant par exemple solidarisée au bord périphérique 6 par exemple par collage ou par soudure. Alternatively, the intermediate sole 9 may be attached peripherally to the outsole 2 and / or the rod 1, for example being secured to the peripheral edge 6 for example by gluing or welding.
Afin de conférer à l'article chaussant une meilleure flexibilité, la semelle intermédiaire 9 et/ou la semelle d'usure 2 est équipée d'un réseau de sillons 13 formant des charnières de déformation qui sont agencées pour faciliter l'enroulé et le déroulé du pied dans le logement 3. In order to give the article of footwear greater flexibility, the midsole 9 and / or the outsole 2 is equipped with a network of grooves 13 forming deformation hinges which are arranged to facilitate the wrapping and unwinding foot in housing 3.
En outre, un réseau de nervures 14 est disposé en regard du réseau de sillons 13, lesdits réseaux étant agencés pour être positionnés l'un dans l'autre afin de favoriser le maintien de la semelle intermédiaire 9 dans le logement 3 tout en autorisant des mouvements relatifs entre les nervures 14 et les sillons 13 lors de la flexion conjointe des semelles intermédiaire 9 et d'usure 2. In addition, a network of ribs 14 is arranged facing the network of grooves 13, said networks being arranged to be positioned one inside the other to promote the maintenance of the midsole 9 in the housing 3 while allowing relative movements between the ribs 14 and the grooves 13 during the joint flexion of the intermediate soles 9 and wear 2.
En particulier, les mouvements relatifs entre les sillons 13 et les nervures 14 permettent de dissocier la déformation de la semelle d'usure 2 de celle de la semelle intermédiaire 9, limitant ainsi l'effort nécessaire à la flexion conjointe desdites semelles d'usure et intermédiaire par appui sur le sol lors du déroulé du pied. Ainsi les fonctions de résistance et d'amortissement de chacune des semelles d'usure 2 et intermédiaire 9 sont conservées à l'usage tout en améliorant leur flexibilité. In particular, the relative movements between the grooves 13 and the ribs 14 make it possible to dissociate the deformation of the outsole 2 from that of the intermediate soleplate 9, thus limiting the force required for the joint flexion of said outsoles and intermediate by support on the ground during the unwinding of the foot. Thus, the resistance and damping functions of each of the wear soles 2 and intermediate 9 are retained in use while improving their flexibility.
En relation avec les figures, le réseau de sillons 13 s'étend dans la paroi inférieure 10 de la semelle intermédiaire 9, le réseau de nervures 14 s'étendant sur la paroi supérieure 1 1 de la semelle d'usure 2. Les nervures 14 s'étendent en outre dans l'épaisseur de la semelle d'usure 2 pour former des sillons 15 dans sa paroi inférieure 8 d'appui au sol de manière à contribuer à l'amélioration de la flexibilité de ladite semelle d'usure tout en favorisant l'adhérence de la chaussure au sol. In relation to the figures, the network of grooves 13 extends into the bottom wall 10 of the midsole 9, the network of ribs 14 extending on the upper wall 1 1 of the outsole 2. The ribs 14 extend further in the thickness of the outsole 2 to form grooves 15 in its bottom wall 8 of support to the ground so as to contribute to improving the flexibility of said outsole while promoting the grip of the shoe on the ground.
Le nombre et la répartition des sillons 13 et des nervures 14 dépendent du degré de flexibilité souhaitée qui est notamment fonction de l'utilisation de la chaussure. De manière avantageuse, les sillons 13 et les nervures 14 s'étendent au moins dans les parties de semelle subissant les pressions maximales du pied en flexion, notamment lors de l'attaque dudit pied au sol, afin de favoriser l'enroulé et le déroulé dudit pied lors de l'appui. En particulier, les sillons 13 et les nervures 14 peuvent être uniquement ou principalement disposés au niveau de l'avant du pied. The number and the distribution of grooves 13 and ribs 14 depend on the degree of flexibility desired, which depends in particular on the use of the shoe. Advantageously, the grooves 13 and the ribs 14 extend at least in the sole portions undergoing the maximum flexural foot pressure, in particular during the attack of said foot on the ground, in order to favor the wrapping and unwinding. said foot during the support. In particular, the grooves 13 and the ribs 14 may be solely or mainly arranged at the forefoot.
La profondeur des sillons 13 et la hauteur des nervures 14 peuvent varier en fonction de la flexibilité de la chaussure souhaitée et/ou de leur disposition au sein des réseaux. Les sillons 13 et les nervures 14 peuvent également être formés de manière à présenter une inclinaison par rapport au plan horizontal de la chaussure, notamment selon leur disposition au sein des réseaux, pouvant être inclinés vers l'avant ou vers l'arrière de ladite chaussure pour limiter la déformation des matériaux sans perte de flexibilité lors d'une flexion longitudinale. The depth of the grooves 13 and the height of the ribs 14 may vary depending on the flexibility of the desired shoe and / or their arrangement within the networks. The grooves 13 and the ribs 14 can also be formed so as to have an inclination relative to the horizontal plane of the shoe, in particular according to their arrangement within the networks, which can be inclined forwards or backwards of said shoe to limit the deformation of the materials without loss of flexibility during longitudinal bending.
En outre, l'orientation des sillons 13 et des nervures 14 peut différer en fonction des mouvements du pied que l'utilisateur souhaite favoriser. Les réseaux peuvent ainsi présenter un jeu respectivement de sillons 13a et de nervures 14a qui s'étendent transversalement pour favoriser une flexion longitudinale du pied de l'utilisateur. In addition, the orientation of the grooves 13 and the ribs 14 may differ according to the movements of the foot that the user wishes to promote. The networks may thus have a set respectively of grooves 13a and ribs 14a which extend transversely to promote longitudinal flexion of the foot of the user.
En variante ou de manière complémentaire, les réseaux peuvent présenter un jeu respectivement de sillons 13b et de nervures 14b qui s'étendent longitudinalement pour garantir une stabilité latérale du pied ou favoriser les mouvements de supination et/ou de pronation dudit pied selon leurs dimensions relatives. Selon le mode de réalisation représenté sur la figure 1 , les sillons 13a et les nervures 14a transversaux s'étendent entre les côtés médial et latéral respectivement de la semelle intermédiaire 9 et de la semelle d'usure 2. En outre, des sillons 13b et des nervures 14b longitudinaux s'étendent entre respectivement les sillons 13a et les nervures 14a transversaux. Alternatively or in a complementary manner, the networks may have a set respectively of grooves 13b and ribs 14b which extend longitudinally to ensure lateral stability of the foot or to promote the supination and / or pronation movements of said foot according to their relative dimensions. . According to the embodiment shown in FIG. 1, the grooves 13a and the transverse ribs 14a extend between the medial and lateral sides respectively of the midsole 9 and the outsole 2. In addition, grooves 13b and longitudinal ribs 14b extend respectively between the grooves 13a and transverse ribs 14a.
Les sillons 13a et les nervures 14a transversaux sont plus nombreux dans les parties d'avant-pied et de talon des semelles intermédiaire 9 et d'usure 2, afin de faciliter les flexions longitudinales respectivement plantaire et dorsale du pied lors du cycle de la marche, lesdites nervures et lesdits sillons étant plus espacés dans la partie de médio-pied. The grooves 13a and transverse ribs 14a are more numerous in the forefoot and heel portions of the intermediate soles 9 and wear 2, in order to facilitate the longitudinal flexions respectively plantar and dorsal foot during the cycle of walking said ribs and said grooves being further spaced in the midfoot portion.
Les sillons 13 et les nervures 14 présentent chacun une géométrie arrondie ayant une dimension respectivement intérieure et extérieure qui sont agencées pour disposer lesdites sillons sur lesdites nervures entre une position non contrainte en l'absence d'appui au sol et une position contrainte entre le pied et le sol dans laquelle la surface intérieure de chaque sillon 13 épouse la surface extérieure de la nervure 14 correspondante. La dimension intérieure des sillons 13 peut être légèrement supérieure ou égale à la dimension extérieure des nervures 14 sur lesquelles lesdits sillons sont positionnés pour permettre leur plaquage en appui au sol et favoriser leur mouvement relatif en l'absence d'appui. En particulier, les sillons 13 notamment transversaux 13a peuvent présenter une dimension longitudinale qui est supérieure à celles des nervures 14 correspondantes. The grooves 13 and the ribs 14 each have a rounded geometry having an inner and outer dimension, respectively, which are arranged to arrange said grooves on said ribs between an unstressed position in the absence of ground support and a constrained position between the foot. and the floor in which the inner surface of each groove 13 matches the outer surface of the corresponding rib 14. The internal dimension of the grooves 13 may be slightly greater than or equal to the external dimension of the ribs 14 on which said grooves are positioned to allow their plating in support of the ground and promote their relative movement in the absence of support. In particular, the grooves 13 in particular transverse 13a may have a longitudinal dimension which is greater than those of the corresponding ribs 14.
En relation avec la figure 2a, lorsque le pied de l'utilisateur est en appui à plat au sol, la pression dudit pied sur toute la longueur de la semelle intermédiaire 9 induit un plaquage des sillons 13 de ladite semelle intermédiaire sur les nervures 14 de la semelle d'usure 2 correspondantes. In relation with FIG. 2a, when the user's foot is resting flat on the ground, the pressure of said foot along the entire length of the intermediate sole 9 induces a plating of the grooves 13 of said intermediate sole on the ribs 14 of the corresponding outsole 2.
Lorsque le pied est en flexion, par exemple plantaire (figure 2b), la différence de rayon de courbure entre la paroi inférieure 8 et la paroi supérieure 12 provoque un étirement de la semelle d'usure 2 vers la zone d'appui au sol et une compression opposée de la semelle intermédiaire 9, ce qui induit un effort de cisaillement à l'interface entre lesdites semelles. La possibilité de déplacement des nervures 14 dans les sillons 13 permet de dissocier, au moins partiellement, ces deux contraintes au niveau de la zone de la semelle d'usure 2 qui n'est pas pressée contre le sol, permettant ainsi de diminuer la résistance à la flexion conjointe des semelles intermédiaire 9 et d'usure 2. When the foot is in flexion, for example plantar (FIG. 2b), the difference in radius of curvature between the lower wall 8 and the upper wall 12 causes a stretching of the outsole 2 towards the ground support zone and an opposite compression of the intermediate sole 9, which induces a shear force at the interface between said flanges. The possibility of displacement of the ribs 14 in the grooves 13 dissociates, at least partially, these two stresses in the area of the outsole 2 which is not pressed against the ground, thereby reducing the resistance at the joint flexion of the intermediate soles 9 and wear 2.
Sur la figure 3, les nervures transversales 14a sont déplacées par rapport aux sillons 13a dans lesquels elles sont engagées de part et d'autre de la zone de contact de la semelle d'usure 2 avec le sol pour diminuer la résistance à la flexion conjointe des semelles d'usure 2 et intermédiaire 9. In FIG. 3, the transverse ribs 14a are displaced with respect to the grooves 13a in which they are engaged on either side of the zone of contact of the outsole 2 with the ground in order to reduce the resistance to joint bending. wear soles 2 and intermediate 9.
