Description
SEMELLE DE CHAUSSURE SOLE OF A SHOE
La présente invention concerne une structure particulière d'une semelle extérieure d'une chaussure de sport. The present invention relates to a particular structure of an outsole of a sports shoe.
Afin d'améliorer le confort, la rigidité ou les performances, de nombreux développements ont été réalisés par la modification de la structure des semelles extérieures. Ces développements ont abouti par exemple à l'inclusion d'inserts, tels que les documents EP 1 048 233, EP 2 649 896, US 5 528 842 et US 8 141 272, ou à l'insertion d'une plaque notamment composite qui s'étend sur majoritairement toute la longueur du semelage, telle que dans les documents présentés ci-après. To improve comfort, stiffness or performance, many developments have been made by changing the structure of the outer soles. These developments have resulted, for example, in the inclusion of inserts, such as EP 1 048 233, EP 2 649 896, US Pat. No. 5,528,842 and US Pat. No. 8,141,272, or the insertion of a particularly composite plate which extends over most of the length of the sole assembly, as in the documents presented below.
Les documents EP 0 272 082, US 5 052 130, US 5 191 727 et FR 2 993 758, divulguent une semelle extérieure en matériau composite, qui s'étend sur toute la longueur de la chaussure et qui peut être courbée vers le haut dans la région avant de la chaussure. Le document EP 1 100 349 décrit une plaque composite ayant une forme particulière qui s'étend du talon aux doigts de pied. Cette plaque est plus élevée au centre qu'aux extrémités et permet de stabiliser le mouvement latéral du pied. Documents EP 0 272 082, US Pat. No. 5,052,130, US Pat. No. 5,191,727 and FR 2,993,758 disclose an outsole of composite material which extends over the entire length of the shoe and which can be bent upwards in the front region of the shoe. EP 1 100 349 discloses a composite plate having a particular shape extending from the heel to the toes. This plate is higher in the center than at the ends and helps stabilize the lateral movement of the foot.
Le document FR 2 775 875 décrit une semelle additionnelle rigide qui peut être en matériau plastique ou en matériau fibreux composite. Cette semelle additionnelle présente des entailles en quinconce agencées transversalement à la longueur de la semelle. Cette semelle additionnelle apporte une rigidité transversale accrue pour la randonnée sur terrain accidenté. Le document US 4 651 445 décrit une plaque en matériau composite en position supérieure d'un empilement de semelles en matière synthétique, qui apporte une élasticité élevée dans le sens du déroulé du pied et une certaine stabilité latérale. Document FR 2 775 875 describes a rigid additional soleplate which may be made of plastics material or of composite fibrous material. This additional sole has staggered notches arranged transversely to the length of the sole. This additional sole provides increased transverse stiffness for hiking on rough terrain. US 4,651,445 discloses a composite material plate in the upper position of a stack of soles of synthetic material, which provides a high elasticity in the direction of unwinding of the foot and a certain lateral stability.
La présente invention propose ainsi un perfectionnement pour une semelle extérieure d'une chaussure de sport.
Ainsi, la semelle extérieure d'une chaussure, selon l'invention, comprend une structure multicouche comprenant une couche inférieure en matériaux synthétiques, une plaque en matériaux rigides et élastiques et une couche supérieure en matériaux synthétiques, la semelle comprenant un axe médian longitudinal délimitant une partie intérieure d'une partie extérieure, la plaque s' étendant de l'extrémité distale de l'avant-pied à la zone d'appui du talon, tandis que la plaque comprend un évidement débouchant vers la périphérie distale de la semelle. The present invention thus provides an improvement for an outsole of a sports shoe. Thus, the outsole of a shoe, according to the invention, comprises a multilayer structure comprising a lower layer of synthetic materials, a plate of rigid and elastic materials and a top layer of synthetic materials, the sole comprising a longitudinal median axis delimiting an inner portion of an outer portion, the plate extending from the distal end of the forefoot to the heel bearing zone, while the plate comprises a recess opening toward the distal periphery of the sole.
Ajoutons que l'évidement est débouchant vers la périphérie extérieure de l'avant-pied. Let us add that the recess is opening towards the outer periphery of the forefoot.
Notons que l'évidement est centré ou sensiblement centré par rapport à l'axe médian longitudinal. Note that the recess is centered or substantially centered with respect to the longitudinal median axis.
Précisons que l'évidement s'étend vers l'arrière, sensiblement au niveau de la zone centrale de l'avant-pied. Selon une caractéristique, l'évidement est bordé ou sensiblement bordé latéralement de part et d'autre par un premier axe oblique et un second axe oblique, agencé en opposition par rapport à l'axe médian longitudinal, ces deux axes obliques passant par l'extrémité proximale de la semelle extérieure et faisant un angle avec l'axe médian longitudinal compris entre 2 et 15 degrés, préférentiellement compris entre 3 et 10 degrés. It should be noted that the recess extends rearward, substantially at the level of the central zone of the forefoot. According to one characteristic, the recess is bordered or substantially bordered laterally on either side by a first oblique axis and a second oblique axis, arranged in opposition with respect to the longitudinal median axis, these two oblique axes passing through the proximal end of the outsole and making an angle with the longitudinal median axis of between 2 and 15 degrees, preferably between 3 and 10 degrees.
Selon une caractéristique supplémentaire, le profil de la plaque, de l'avant vers l'arrière, se rétrécit en largeur. According to an additional characteristic, the profile of the plate, from front to rear, narrows in width.
Selon un mode de réalisation, la plaque présente une courbure vers le haut, relevée à la fois à l'avant et à l'arrière. Ajoutons que l'évidement délimite la plaque au niveau de l'avant- pied en une branche intérieure et une branche extérieure. According to one embodiment, the plate has an upward curvature, raised both at the front and at the back. Let us add that the recess delimits the plate at the level of the forefoot into an inner branch and an outer branch.
Selon une caractéristique complémentaire, la branche intérieure s'étend vers l'extrémité distale de l'avant-pied transversalement vers l'extérieur, formant une zone transversale d'appui.
D'autres caractéristiques et avantages de l'invention se dégageront de la description qui va suivre, en regard des dessins annexés qui ne sont donnés qu'à titre d'exemples non limitatifs. According to a complementary feature, the inner limb extends towards the distal end of the forefoot transversely outwards, forming a transverse bearing zone. Other features and advantages of the invention will become apparent from the description which follows, with reference to the accompanying drawings which are given by way of non-limiting examples.
Les figures 1 à 9 sont des vues d'une semelle extérieure d'une chaussure de pied gauche, selon un mode de réalisation de l'invention. Figures 1 to 9 are views of an outsole of a left foot shoe, according to one embodiment of the invention.

La figure 9 est une vue en coupe transversale selon G, G'. Une chaussure est communément équipée d'une semelle extérieureFigure 9 is a cross-sectional view along G, G '. A shoe is commonly equipped with an outsole
(1) multicouche surmontée d'une tige équipée d'une enveloppe, dans laquelle est retenu le pied de l'utilisateur. L'enveloppe a sensiblement la forme du pied de l'utilisateur, et comprend des moyens de retenue, tels que des lacets. (1) multilayer surmounted by a rod equipped with an envelope, in which the foot of the user is retained. The envelope has substantially the shape of the foot of the user, and comprises retaining means, such as laces.
Selon une caractéristique, la tige surmonte la semelle extérieure (1) pour y être encastrée par sa partie basse. La tige est, bien entendu, solidarisée
à la semelle extérieure (1), par tout moyen approprié connu, tel que par collage, et est retenue, par sa partie basse, par un rebord périphérique constitué par une paroi s' étendant vers le haut, entourant donc la partie basse de la tige. En d'autres termes, la partie supérieure de la semelle extérieure (1) comprend une cuvette centrale constituée par un profil en creux ouvert vers le haut destiné à recevoir la tige, la cuvette étant formée par le rebord périphérique. According to one characteristic, the upper overcomes the outsole (1) to be recessed by its lower part. The stem is, of course, secured to the outsole (1), by any appropriate means known, such as by gluing, and is retained, by its lower part, by a peripheral rim constituted by a wall extending upwards, thus surrounding the lower part of the rod. In other words, the upper portion of the outsole (1) comprises a central bowl constituted by an upwardly open recessed profile intended to receive the rod, the bowl being formed by the peripheral rim.
11 est également entendu que la chaussure, selon l'invention, peut être équipée d'une semelle intérieure encollée ou amovible. Selon le mode de réalisation illustré, la semelle extérieure (1) est courbée vers le haut, à la fois dans sa partie avant et dans sa partie arrière, telle que divulguée par le document FR 2 945 916. It is also understood that the shoe, according to the invention, can be equipped with a glue or removable insole. According to the illustrated embodiment, the outsole (1) is curved upwards, both in its front part and in its rear part, as disclosed by the document FR 2 945 916.
Lorsque qu'un utilisateur court sur de longues distances, une foulée se décompose, par tout d'abord l'appui du talon au sol, suivi par le déroulé du pied sur la majorité de sa surface inférieure, jusqu'à un appui prononcé de la pointe du pied. Ce type de foulée est différent par rapport à celui d'une course rapide sur de courtes distances, telle que lors d'un sprint, où les foulées sont majoritairement centrées sur la pointe du pied. When a user is running long distances, a stride decomposes, first of all by pressing the heel to the ground, followed by the unwinding of the foot on the majority of its lower surface, until a pronounced support of tiptoe. This type of stride is different from that of a fast race over short distances, such as during a sprint, where the strides are mainly centered on the tip of the foot.
Ainsi, une chaussure présentant une courbure, telle que la caractéristique précédemment décrite, à savoir, relevée à la fois à l'avant et à l'arrière de la chaussure, favorise et accentue le déroulement du pied sur la surface d'appui au sol lors des foulées de l'utilisateur. Thus, a shoe having a curvature, such as the feature described above, namely, raised both at the front and back of the shoe, promotes and accentuates the unfolding of the foot on the ground support surface during the strides of the user.
Il est entendu que selon d'autres modes de réalisation, la semelle extérieure (1) peut-être uniquement courbée vers le haut dans sa partie avant, telle que la majorité des chaussures du marché. It is understood that according to other embodiments, the outsole (1) may only be curved upwards in its front part, such as the majority of shoes on the market.
Π est également entendu que la semelle extérieure (1) s'étend vers l'avant en correspondance de l'extrémité antérieure ou distale du pied au niveau des orteils, vers le centre au niveau de l'arche du pied, et vers l'arrière en correspondance de l'extrémité postérieure ou proximale du pied au niveau du talon. It is also understood that the outsole (1) extends forwardly in correspondence of the anterior or distal end of the foot at the toes, towards the center at the arch of the foot, and towards the back in correspondence of the posterior or proximal end of the foot at the heel.
La semelle extérieure (1), telle qu'illustrée à la figure le et 2, comprend un axe médian longitudinal (X, X') délimitant une partie intérieure
(PI) d'une partie extérieure (PE), tandis que la partie extérieure (PE) comprend un premier axe oblique (W, W) passant par l'extrémité proximale (15) de la semelle extérieure (1), et faisant un angle avec l'axe médian longitudinal (X, X') compris entre 2 et 15 degrés, préférentiellement entre 3 et 10 degrés, plus préférentiellement entre 3 et 7 degrés. Précisons que la partie intérieure (PI) comprend un second axe oblique (Y, Y') passant également par l'extrémité proximale (15) de la semelle extérieure (1) et faisant un angle avec l'axe médian longitudinal (X, X') compris entre 2 et 15 degrés, préférentiellement entre 3 et 10 degrés, plus préférentiellement entre 3 et 7 degrés, en opposition du premier axe oblique (W, W) par rapport à l'axe médian longitudinal (X, X'). The outsole (1), as illustrated in Figure 1a and 2, comprises a longitudinal median axis (X, X ') delimiting an inner portion (PI) of an outer portion (PE), while the outer portion (PE) comprises a first oblique axis (W, W) passing through the proximal end (15) of the outsole (1), and making a angle with the longitudinal median axis (X, X ') between 2 and 15 degrees, preferably between 3 and 10 degrees, more preferably between 3 and 7 degrees. It should be noted that the inner portion (PI) comprises a second oblique axis (Y, Y ') also passing through the proximal end (15) of the outsole (1) and making an angle with the longitudinal median axis (X, X ') between 2 and 15 degrees, preferably between 3 and 10 degrees, more preferably between 3 and 7 degrees, opposite the first oblique axis (W, W) with respect to the longitudinal median axis (X, X').
La plante du pied ou la face inférieure du squelette du pied est constituée de trois parties, à savoir, d'arrière en avant, le tarse, le métatarse et les phalanges. Le métatarse et les phalanges correspondent à l'avant-pied. La semelle extérieure (1) selon l'invention, telle qu'illustrée aux figures 1 à 9, se présente sous la forme d'une structure multicouche, comprenant une couche inférieure (2) en matériau(x) synthétique (s), une plaque (3) en matériau(x) rigide(s) et élastique(s), et une couche supérieure (4) en matériau(x) synthétique(s). Selon le mode de réalisation illustré, la plaque (3) s'étend avantageusement sur toute la longueur ou sensiblement toute la longueur de la semelle extérieure (1). Plus précisément, la plaque s'étend longitudinalement de l'extrémité des phalanges à la zone d'appui du talon (10), telle qu'illustrée à la figure 2. Une plaque (3) en matériau(x) rigide(s) et élastique(s) a des propriétés à accumuler de l'énergie lors de sa flexion et de libérer cette énergie lors de sa détente. Ce/ ces matériau(x) sont par exemple un composite à base de fibre tissée ou non tissée, par exemple en fibre de verre, en fibre de carbone, en fibre métallique telle qu'en aluminium ou en titane ou un mélange de fibres, tel qu'un mélange de fibre de verre et de fibre de carbone. Ces fibres tissées ou non tissées sont enrobées d'une matrice polymère, telle qu'en polyuréthane ou en résine époxy.
Selon des modes de réalisation la plaque (3) composite peut être en fibres de carbone enrobées d'une résine polyuréthane ou en fibres de verre enrobées d'une résine polyester. The sole of the foot or the underside of the skeleton of the foot is made up of three parts, namely, from behind forwards, the tarsus, the metatarsus and the phalanges. The metatarsal and the phalanges correspond to the forefoot. The outer sole (1) according to the invention, as illustrated in FIGS. 1 to 9, is in the form of a multilayer structure, comprising a lower layer (2) of synthetic material (s), a plate (3) of rigid (s) material (s) and elastic (s), and an upper layer (4) of synthetic material (s). According to the illustrated embodiment, the plate (3) advantageously extends over the entire length or substantially the entire length of the outer sole (1). More specifically, the plate extends longitudinally from the end of the phalanges to the bearing zone of the heel (10), as shown in Figure 2. A plate (3) of rigid material (s) (s) and elastic (s) has properties to accumulate energy during its flexion and release this energy during its relaxation. This / these material (s) are for example a composite based on woven or non-woven fiber, for example fiberglass, carbon fiber, metal fiber such as aluminum or titanium or a mixture of fibers, such as a mixture of fiberglass and carbon fiber. These woven or non-woven fibers are coated with a polymer matrix, such as polyurethane or epoxy resin. According to embodiments, the composite plate (3) may be made of carbon fibers coated with a polyurethane resin or glass fibers coated with a polyester resin.
Une plaque (3) en matériau rigide et élastique peut être également en fibres synthétiques enrobées d'une résine polymère, par exemple en fibres d'aramide (kevlar) enrobées d'une résine époxy. A plate (3) of rigid and elastic material may also be synthetic fibers coated with a polymer resin, for example aramid fibers (kevlar) coated with an epoxy resin.
La plaque (3) peut-être également en matériaux polymères, tels qu'en polycarbonate (PC), en polyuréthane (PU), en acrylonitrile butadiène styrène (ABS) ou en polyéther bloc amide (PEBA). The plate (3) may also be made of polymeric materials, such as polycarbonate (PC), polyurethane (PU), acrylonitrile butadiene styrene (ABS) or polyether block amide (PEBA).
Selon un mode de réalisation préféré, notamment pour une chaussure destinée à la compétition, la plaque (3) est en fibres de carbone enrobées d'une matrice polyuréthane. According to a preferred embodiment, in particular for a shoe intended for competition, the plate (3) is made of carbon fibers coated with a polyurethane matrix.
Selon un autre mode de réalisation, notamment pour une chaussure destinée aux sports de loisir, la plaque (3) est en matériau(x) polymère(s). According to another embodiment, in particular for a shoe intended for leisure sports, the plate (3) is made of polymer material (s).
Ainsi lors d'une foulée où l'utilisateur pose son talon au sol, il déroule son pied jusqu'à prendre appui sur la pointe de son pied, la plaque à effet ressort, accumule de l'énergie lors de la phase du déroulé et la libère en fin de foulée, afin d'apporter une propulsion à chacune des foulées de l'utilisateur. Thus during a stride where the user puts his heel on the ground, he unrolls his foot to rest on the tip of his foot, the plate spring effect, accumulates energy during the phase of the unwinding and release it at the end of the stride, to bring a propulsion to each stride of the user.
Selon le mode de réalisation illustré, la plaque (3) a une forme particulière notamment à son extrémité distale et à la zone correspondant à I'avant-pied (5). According to the illustrated embodiment, the plate (3) has a particular shape, in particular at its distal end and at the zone corresponding to the forefoot (5).
La plaque (3) comprend ainsi un évidement (7) sous une forme d'une découpe dans sa partie distale, débouchant vers la périphérie extérieure de la semelle extérieure (1), avantageusement à la périphérie distale au niveau de la partie extérieure (PE), à savoir la périphérie extérieure de l'avant pied (5). The plate (3) thus comprises a recess (7) in the form of a cutout in its distal portion, opening towards the outer periphery of the outsole (1), advantageously at the distal periphery at the outer portion (PE ), namely the outer periphery of the forefoot (5).
Selon le mode de réalisation illustré, cet évidement (7) est centré ou sensiblement centré par rapport à l'axe médian longitudinal (X, X') et délimité ou sensiblement délimité latéralement par le premier axe oblique (W, W) et le deuxième axe oblique (Y, Y'), tel qu'illustré aux figures le et 2.
Cet évidement (7) s'étend vers l'arrière, à son extrémité proximale, sensiblement entre la jonction des zones correspondantes des phalanges et du métatarse, préférentiellement sensiblement au niveau de la zone centrale (11) de l'avant-pied (5), plus préférentiellement en dessous de la zone centrale (11) de l'avant-pied (5), tout en étant dans la zone correspondante au métatarse. According to the illustrated embodiment, this recess (7) is centered or substantially centered with respect to the longitudinal median axis (X, X ') and delimited or substantially delimited laterally by the first oblique axis (W, W) and the second oblique axis (Y, Y '), as illustrated in Figures 1 and 2. This recess (7) extends rearward, at its proximal end, substantially between the junction of the corresponding zones of the phalanges and the metatarsus, preferably substantially at the level of the central zone (11) of the forefoot (5). ), more preferably below the central zone (11) of the forefoot (5), while being in the zone corresponding to the metatarsal.
Cet évidement (7) délimite latéralement la zone supérieure de la plaque (3) en deux branches (8, 9), à savoir une branche intérieure (8) et une branche extérieure (9). En d'autres termes, la plaque (3) est prolongée vers son extrémité distale en deux branches (8, 9) longitudinales. L'extrémité distale de la branche extérieure (9) est alignée ou sensiblement alignée avec le premier axe oblique (W, W), tandis que l'extrémité distale de la branche intérieure (8) est alignée ou sensiblement alignée avec le second axe oblique (Y, Y'). This recess (7) delimits laterally the upper zone of the plate (3) in two branches (8, 9), namely an inner branch (8) and an outer branch (9). In other words, the plate (3) is extended towards its distal end in two longitudinal branches (8, 9). The distal end of the outer leg (9) is aligned or substantially aligned with the first oblique axis (W, W), while the distal end of the inner leg (8) is aligned or substantially aligned with the second oblique axis (Y, Y ').
Précisons que l'extrémité distale de la branche extérieure (9) s'étend au moins jusqu'à la zone correspondant au cinquième orteil, tandis que l'extrémité distale de la branche intérieure (8) s'étend au moins jusqu'à la zone correspondant au premier orteil. Note that the distal end of the outer branch (9) extends at least to the area corresponding to the fifth toe, while the distal end of the inner branch (8) extends at least to the area corresponding to the first toe.
Selon une caractéristique, l'extrémité distale de la branche intérieureAccording to one characteristic, the distal end of the inner branch
(8) s'étend transversalement vers l'extérieur, de préférence, jusqu'à la périphérie extérieure de la semelle (1). L'évidement (7) est ainsi bordé dans sa partie distale par la zone transversale (12) de la branche intérieure (8). (8) extends transversely outwards, preferably to the outer periphery of the sole (1). The recess (7) is thus bordered in its distal portion by the transverse zone (12) of the inner branch (8).
Selon la caractéristique précédente, l'extrémité distale de la plaque (3), à savoir l'extrémité distale de la branche intérieure (8) est centrée ou sensiblement centrée sur le second axe oblique (Y, Y'). La structure particulière de la zone d'avant-pied (5) de la plaque (3), à savoir, la présence de la branche intérieure (8) et de la branche extérieureAccording to the preceding feature, the distal end of the plate (3), namely the distal end of the inner limb (8) is centered or substantially centered on the second oblique axis (Y, Y '). The particular structure of the forefoot zone (5) of the plate (3), namely, the presence of the inner branch (8) and the outer branch
(9) , permet d'apporter un effet ressort non seulement modulé, voire différent, entre la partie intérieure (PI) et extérieure (PE) de la semelle extérieure (1), mais également par la structure de l'extrémité distale de la branche intérieure (8), d'obtenir un effet de propulsion augmenté par la zone transversale (12) d'appui à la pointe du pied.
En effet, l'extrémité distale de la branche intérieure (8) s'étendant transversalement vers l'extérieur, permet un appui prononcé d'au moins le premier, le second et avantageusement le troisième orteil. (9), makes it possible to provide a spring effect not only modulated, or even different, between the inner (PI) and outer (PE) part of the outsole (1), but also by the structure of the distal end of the inner branch (8), to obtain an increased propulsion effect by the transverse zone (12) of support at the tip of the foot. Indeed, the distal end of the inner branch (8) extending transversely outwardly, allows a pronounced support of at least the first, the second and preferably the third toe.
Selon une caractéristique supplémentaire, le profil de la plaque (3), de l'avant vers l'arrière, se rétrécit en largeur, afin d'obtenir une partie centrale et proximale, correspondant à la zone de l'arche et la zone d'appui du talon (10), ayant une flexibilité supérieure par rapport à la partie supérieure de la plaque correspondant à l'avant-pied (5). Cette flexibilité accrue de la plaque (3), dans la zone centrale et proximale, augmente la capacité de propulsion de la semelle extérieure (1) et donc de la foulée de l'utilisateur lors de son avancée. According to an additional characteristic, the profile of the plate (3), from front to rear, narrows in width, in order to obtain a central and proximal part, corresponding to the zone of the arch and the zone of heel support (10), having greater flexibility with respect to the upper part of the plate corresponding to the forefoot (5). This increased flexibility of the plate (3), in the central and proximal zone, increases the propulsion capacity of the outsole (1) and therefore the stride of the user during its advance.
Précisons que selon le mode de réalisation illustré, notamment aux figures lb et d, la plaque (3) épouse la forme de la semelle extérieure (1). La plaque (3) présente ainsi une courbure, relevée à la fois à l'avant et à l'arrière. La combinaison de cette courbure, favorisant le déroulé du pied, et de la structure particulière de la plaque (3), contribue à accroître la capacité de propulsion de la semelle extérieure (1). Note that according to the illustrated embodiment, particularly in Figures lb and d, the plate (3) matches the shape of the outer sole (1). The plate (3) thus has a curvature, raised both at the front and at the back. The combination of this curvature, favoring the unwinding of the foot, and the particular structure of the plate (3), contributes to increase the propulsion capacity of the outsole (1).
Ainsi la zone centrale de la plaque (3) correspondante à la zone de l'arche, est sensiblement rectiligne, voir présente une légère courbure relevée à la fois à l'avant et à l'arrière. Thus the central area of the plate (3) corresponding to the area of the arch, is substantially rectilinear, see has a slight curvature raised both at the front and rear.
Selon une caractéristique supplémentaire, le profil de la plaque (3) est légèrement désaxé par rapport à l'axe médian longitudinal (X, X') de la semelle extérieure (1), dirigé vers la partie intérieure (PE). En outre, la plaque (3) a une certaine courbure transversale, opposée à celle de la semelle extérieure (1) qui est dirigée communément vers l'intérieur, notamment à son extrémité proximale, telle qu'illustrée aux figures 7 et 8. According to an additional characteristic, the profile of the plate (3) is slightly off-axis with respect to the longitudinal median axis (X, X ') of the outer sole (1), directed towards the inner part (PE). In addition, the plate (3) has a certain transverse curvature, opposite that of the outsole (1) which is commonly directed inwards, in particular at its proximal end, as illustrated in FIGS. 7 and 8.
Rappelons que la semelle extérieure (1) se présente par une structure multicouche comprenant une plaque (3) agencée entre une couche inférieure (2) et une couche supérieure (4). La couche inférieure (2) de la semelle extérieure (1), selon le mode de réalisation illustré, comprend deux types de zones, à savoir des zones
d'accroché (13) en matériaux rigides, et des zones d'amortissement (14) en matériaux moins rigides, voire tendres. Recall that the outer sole (1) is a multilayer structure comprising a plate (3) arranged between a lower layer (2) and an upper layer (4). The lower layer (2) of the outer sole (1), according to the illustrated embodiment, comprises two types of zones, namely zones hooked (13) of rigid materials, and damping areas (14) of less rigid materials or soft.
Les zones d'accroché (13) sont localisées au niveau de la partie intérieure (PE) avant, plus précisément au niveau de la zone intérieure de l'avant-pied (5), et agencées de manière latérale de part et d'autre de l'axe médian longitudinal (X, X'), au niveau de la partie arrière, en périphérie de la zone d'appui du talon (10). The hooked areas (13) are located at the level of the inner part (PE) before, more precisely at the level of the inner area of the forefoot (5), and arranged laterally on both sides of the longitudinal median axis (X, X '), at the rear portion, at the periphery of the heel support zone (10).
Les zones d'amortissement (14) sont réparties sur toute la surface inférieure de la semelle extérieure (1) en complémentarité des zones d'accroché (13). The damping zones (14) are distributed over the entire lower surface of the outsole (1) in complementarity of the hooked areas (13).
Ces zones d'amortissement (14) permettent comme leurs noms l'indiquent, d'amortir les impacts au contact du sol, ce qui est d'autant plus important par rapport à une semelle extérieure conventionnelle, de par la présence de la plaque (3). La couche supérieure (4) s'étend de préférence de l'extrémité distale à l'extrémité proximale de la semelle extérieure (1), mais il pourrait en être autrement, la couche supérieure (4) s'étend de la partie centrale à la partie proximale. These damping zones (14) allow, as their names indicate, to damp the impacts in contact with the ground, which is all the more important compared to a conventional outsole, due to the presence of the plate ( 3). The upper layer (4) preferably extends from the distal end to the proximal end of the outsole (1), but it could be otherwise, the upper layer (4) extends from the central portion to the proximal part.
Selon le mode de réalisation illustré, la couche supérieure (4) s'étend sur toute la longueur de la semelle extérieure (1). According to the illustrated embodiment, the upper layer (4) extends over the entire length of the outer sole (1).
Selon des modes de réalisation, la couche supérieure (4) comprend différentes zones qui sont produites en différant matériaux ou en un matériau ayant différentes densités, par exemple en EVA de différentes densités. According to embodiments, the upper layer (4) comprises different zones that are produced by differing materials or a material having different densities, for example EVA of different densities.
Selon les modes de réalisation précédents, la zone correspondant à l'avant pied (5) est constituée d'un premier matériau, tandis que la zone d'appui du talon (10) est constituée d'un second matériau. De préférence, le second matériau a une capacité d'amortissement supérieur au premier matériau. According to the preceding embodiments, the zone corresponding to the forefoot (5) consists of a first material, while the heel support zone (10) consists of a second material. Preferably, the second material has a greater damping capacity than the first material.
Les couches supérieure (4) et inférieure (2) sont par exemple en polyuréthane (PU), en polyéthylène (PE), en polyéthylène acétate de vinyle (PEVA), préférentiellement en polyéthylène acétate de vinyle.
Selon un mode d'exécution, les couches supérieure (4) et inférieure (2) sont réalisées dans un même matériau, mais il pourrait en être autrement, les couches (2, 4) sont réalisées dans des matériaux différents. The upper (4) and lower (2) layers are for example polyurethane (PU), polyethylene (PE), polyethylene vinyl acetate (PEVA), preferably polyethylene vinyl acetate. According to one embodiment, the upper (4) and lower (2) layers are made of the same material, but it could be otherwise, the layers (2, 4) are made of different materials.
Selon un autre mode d'exécution, les couches supérieure (4) et inférieure (2) ont une densité différente, par exemple en EVA de différentes densités. According to another embodiment, the upper (4) and lower (2) layers have a different density, for example EVA of different densities.
Selon des modes de réalisation, la couche supérieure (4) est confondue avec la semelle intérieure. According to embodiments, the upper layer (4) is merged with the insole.
La structure multicouche de la semelle extérieure apporte non seulement un effet ressort, produisant une propulsion à chaque foulée, mais également un confort d'utilisation à l'utilisateur.
The multilayer structure of the outsole not only provides a spring effect, producing a propulsion at each stride, but also a comfort of use to the user.
