Abstract
Description
La présente invention a pour objet un dispositif d'appui d'un pied dans une chaussure de sport et/ou de loisirs, et un procédé d'obtention de ce dispositif.The subject of the present invention is a support device for a foot in a sports and / or leisure shoe, and a method obtaining this device.
L'importance de l'appui d'un pied dans une chaussure, qu'il s'agisse d'une chaussure de ville, ou d'une chaussure de sport et/ou de loisirs, est reconnue depuis longtemps. Pour améliorer cet appui ou corriger certains défauts du pied, des semelles sont utilisées.The importance of the support of a foot in a shoe, that it a city shoe, or a sports shoe and / or leisure, has long been recognized. To improve this support or correct some foot defects, soles are used.
Les semelles dites orthopédiques sont destinées à modifier l'équilibre des chaínes articulaires en recréant des arches qui se sont effondrées. De telles semelles, dites correctives, sont très peu utilisées pour la pratique du sport, car elles sont traumatisantes.The so-called orthopedic insoles are intended to modify the balance of the articular chains by recreating arches which are collapsed. Such soles, called corrective, are used very little for the practice of sport, because they are traumatic.
Certaines semelles, dites proprioceptives, intègrent des surépaisseurs destinées à stimuler ou inhiber les récepteurs plantaires et modifier une tension musculaire parasite ou un déséquilibre posturostatique.Some soles, called proprioceptive, incorporate extra thicknesses intended to stimulate or inhibit plantar receptors and change parasitic muscle tension or imbalance posturostatique.
Le document FR-A.2286 638 concerne une semelle orthopédique pour corriger la rotation interne des pieds chez les jeunes enfants. Cette semelle comporte un premier coin s'étendant au niveau de la partie proximale du premier métatarse et en arrière de cette partie et un second coin s'étendant dans le prolongement du premier, vers l'arrière de la semelle, toujours du côté du bord intérieur de celle-ci. Il s'agit dans un tel cas d'exercer une action corrective permanente.Document FR-A.2286 638 relates to a sole orthopedic to correct the internal rotation of the feet in young people children. This sole has a first wedge extending at the level of the proximal part of the first metatarsus and behind that part and a second corner extending in the extension of the first, towards the rear of the sole, always on the side of the inner edge thereof. It comes in a such case to exercise a permanent corrective action.
Le document US-A.2 884 719 décrit une semelle ou un dispositif intégré à une chaussure visant à soigner une métatarsalgie en tentant de répartir les charges pour éviter un appui trop ponctuel. Ce dispositif comprend une cale s'étendant dans la zone centrale et proximale du premier métatarse ainsi que dans les parties proximales des second et troisième métatarse.Document US-A.2 884 719 describes a sole or a device integrated into a shoe intended to treat metatarsalgia in trying to distribute the loads to avoid a too punctual support. This device includes a wedge extending in the central and proximal area of the first metatarsus as well as in the proximal parts of the second and third metatarsus.
Le document US-A.2 660 814 décrit une semelle de chaussure visant à répartir les charges en mettant en oeuvre un nombre important de cales, dont essentiellement une cale sous les trois premiers métatarses et une cale en forme de fer à cheval soutenant la voûte plantaire et entourant l'extérieur du talon.Document US-A.2 660 814 describes a shoe sole aimed at distributing the loads by implementing a large number of holds, including essentially a hold under the first three metatarsals and a horseshoe-shaped wedge supporting the arch and surrounding the outside of the heel.
Il existe également des semelles thermoformables, dites physiologiques, et moulées directement sur le pied, très appréciées sur le plan sportif, car elles augmentent la surface d'appui et donnent donc un plus grand confort.There are also thermoformable insoles, called physiological, and molded directly on the foot, much appreciated on the sporting plan, because they increase the support surface and therefore give a greater comfort.
Lors de la marche, on observe un transfert du poids du corps. Lors de l'impact, le pied étant supinateur, le talon touche le sol d'abord sur son bord latéral externe. Le pied subit alors une force pronatrice. L'appui se poursuit le long de l'arche externe du pied, puis sur la cinquième et sur les autres têtes métatarsiennes jusqu'au gros orteil au moment de la phase finale de propulsion. Pendant ce temps, le centre de poussée devient central, puis se porte sur l'intérieur de l'avant-pied entre les première et deuxième têtes métatarsiennes, c'est-à-dire la partie antéro-médiale du pied, plus ou moins en dedans selon les individus.While walking, there is a transfer of body weight. On impact, the foot being a supinator, the heel touches the ground first on its outer lateral edge. The foot then undergoes a pronating force. The support continues along the external arch of the foot, then on the fifth and on the other metatarsal heads to the big toe at moment of the final propulsion phase. Meanwhile, the center of thrust becomes central, then goes on the inside of the forefoot between the first and second metatarsal heads, i.e. the part antero-medial of the foot, more or less inward depending on the individual.
En accélérant le mouvement, c'est-à-dire lors d'un mouvement de course, le centre de poussée se porte beaucoup plus sur l'intérieur pendant les phases d'appui et de propulsion. Ce phénomène est amplifié lors de gestes sportifs nécessitant un appui important sur l'intérieur, par exemple, lors de la pratique du ski, du patin, du golf ou de la course lors de changements de direction, accélérations ou décélérations, notamment sur des terrains en dévers.By accelerating the movement, that is to say during a movement of racing, the center of thrust is much more on the inside during the support and propulsion phases. This phenomenon is amplified during sports gestures requiring significant support on the inside, for example example, when skiing, skating, golfing or running when changes of direction, accelerations or decelerations, in particular on slopes.
Ce mouvement biomécanique du pied, dit prono-supinateur, s'accompagne d'une rotation de l'axe jambier formé par le tibia et le péroné. La supination entraínant la rotation externe du squelette jambier et la pronation entraínant la rotation interne du squelette jambier, l'équilibre entre ces rotations et la contre-rotation engendrée par l'appui au sol est principalement régulé par le muscle long péronier latéral.This biomechanical movement of the foot, called prono-supinator, is accompanied by a rotation of the leg axis formed by the tibia and the fibula. The supination causing the external rotation of the leg skeleton and pronation causing internal rotation of the leg skeleton, balance between these rotations and the counter-rotation generated by the ground support is mainly regulated by the long lateral peroneal muscle.
Dans les cas d'appuis extrêmes, tels que ceux résultant des sports indiqués ci-dessus, et d'appuis répétés, apparaissent souvent des irritations ligamentaires et tendineuses dues à la fatigue musculaire qui peut se manifester sous forme de crampes. En outre, le muscle long péronier latéral, sollicité au-delà de son amplitude habituelle, perd son rôle de contrôle prono-supinateur, diminuant la performance escomptée.In cases of extreme support, such as those resulting from sports indicated above, and repeated support, often appear ligament and tendon irritation due to muscle fatigue which may manifest as cramps. In addition, the long muscle lateral fibula, stressed beyond its usual range, loses its role prono-supinator control, reducing the expected performance.
Le but de l'invention est de fournir un dispositif d'appui d'un pied dans une chaussure de sport ou de loisirs, qui vise non pas à corriger une forme de pied mais à freiner et contrôler une pression se portant progressivement sur une zone précise du pied.The object of the invention is to provide a support device for a foot in a sports or leisure shoe, which is not intended to correct a form of foot but to brake and control a pressure bearing gradually over a specific area of the foot.
A cet effet, le dispositif qu'elle concerne, comprend en combinaison un élément de suspension disposé dans la zone servant à l'appui de l'extrémité distale de la première tête métatarsienne du pied et un élément de suspension transversal, disposé dans la zone médio-tarsienne, enveloppant la partie antérieure du talon.To this end, the device which it relates to includes combination a suspension element arranged in the area used to the support of the distal end of the first metatarsal head of the foot and a transverse suspension element, placed in the mid-tarsal area, enveloping the anterior part of the heel.
Avantageuseusement l'élément de suspension servant à l'appui de la première tête métatarsienne est disposé dans la zone servant plus précisément à l'appui du berceau phalango-bisesamoïdien dans lequel s'articule la première tête métatarsienne encroûtée de cartilage.Advantageously the suspension element used for the support of the first metatarsal head is arranged in the area serving more precisely in support of the phalango-bisesamoïdien cradle in which articulates the first metatarsal head encrusted with cartilage.
Lors de la pratique d'un sport, tel que le ski, le patin ou le golf, ou encore au cours de certains mouvements de course à pied, cet élément de suspension a pour fonction de contrôler la pression du pied et de contrôler l'affaissement de l'avant-pied lorsque l'appui s'y porte durant la phase prépropulsive, afin de soulager le muscle long péronier latéral et de conserver à ce dernier toute son efficacité.When playing a sport, such as skiing, skating or golf, or even during certain running movements, this element suspension function is to control the pressure of the foot and control the sag of the forefoot when the support is carried during the pre-propulsive phase, to relieve the long lateral peroneal muscle and keep it effective.
Il doit être noté que les éléments de suspension ne concernent pas les rayons métatarsiens latéraux qui constituent la zone de freinage cinétique du pied, mais seulement le premier rayon métatarsien qui est le seul propulsif et le seul à présenter une flexion plantaire active. La présence d'un élément de suspension dans la zone médio-tarsienne enveloppant la partie antérieure du talon permet, en association avec l'élément de suspension situé dans la zone d'appui de l'extrémité distale de la première tête métatarsienne, de réaliser la mise en tension de l'aponévrose plantaire par la dorsiflexion du gros orteil, connue sous le nom de "Windlass Mechanism". Il en résulte une facilitation du système de verrouillage passif et une augmentation des surfaces d'appui.It should be noted that the suspension elements do not concern not the lateral metatarsal rays which constitute the braking zone kinetics of the foot, but only the first metatarsal ray which is the the only propellant and the only one with active plantar flexion. The presence of a suspension element in the mid-tarsal area enveloping the anterior part of the heel allows, in association with the suspension element located in the support area of the distal end of the first metatarsal head, to realize the tensioning of plantar fascia by dorsiflexion of the big toe, known as name of "Windlass Mechanism". This results in a facilitation of the passive locking and increased support surfaces.
Les éléments de suspension possèdent une épaisseur de l'ordre de 2 à 8 mm et sont réalisés en une matière souple viscoélastique ou à mémoire élastique, telle que, par exemple, en Ethylène Vinyle Acétate EVA d'une dureté shore comprise entre 20 et 50 et d'une densité supérieure à 70 kg/m3, ou en polyéthylène d'une dureté shore comprise entre 60 et 140 et d'une densité supérieure à 100 kg/m3.The suspension elements have a thickness of the order of 2 to 8 mm and are made of a flexible viscoelastic or elastic memory material, such as, for example, Ethylene Vinyl Acetate EVA with a shore hardness of between 20 and 50 and of a density greater than 70 kg / m 3 , or of polyethylene with a shore hardness between 60 and 140 and a density greater than 100 kg / m 3 .
De tels éléments de suspension n'étant pas traumatisants et pouvant convenir à différentes formes de pied d'une même pointure, ils peuvent être compatibles avec un système de production industrielle, que les éléments de suspension soient disposés sur la face inférieure d'une semelle intérieure de chaussure ou sur la face supérieure du fond d'une chaussure. Such suspension elements are not traumatic and may be suitable for different foot shapes of the same size, they can be compatible with an industrial production system, that the suspension elements are arranged on the underside of a shoe insole or on the upper side of the bottom of a shoe.
La densité et l'épaisseur des éléments de suspension sont choisies selon la pointure, l'activité pratiquée et éventuellement le poids de l'utilisateur.The density and thickness of the suspension elements are chosen according to the size, the activity practiced and possibly the weight of the user.
Avantageusement, dans le cas d'une chaussure de golf, le dispositif d'appui peut être complété par un élément de suspension médiotarsien prolongé le long du bord intérieur du talon, afin de favoriser l'équilibre postural et le placement des hanches, et d'orienter le transfert de charge pendant le passage de l'éversion adaptative à l'inversion de rigidification.Advantageously, in the case of a golf shoe, the support device can be completed with a suspension element mediotarsal extended along the inner edge of the heel to promote postural balance and hip placement, and to guide the transfer load during the transition from adaptive eversion to inversion of stiffening.
Les éléments de suspension peuvent également être ménagés sur la face supérieure de la semelle, ou sur le fond de la chaussure, sur la face supérieure de celui-ci ou sur sa face inférieure prenant appui sur le sol.The suspension elements can also be arranged on the upper side of the sole, or on the bottom of the shoe, on the upper face of the latter or on its lower face bearing on the ground.
Les éléments de suspension peuvent être constitués non pas par une matière souple, mais par des zones suspendues d'une semelle préformée.The suspension elements can be made up not by a flexible material, but by suspended areas of a sole preformed.
De préférence, l'élément de suspension possède une gorge longitudinale pour le logement du long fléchisseur propre du premier orteil.Preferably, the suspension element has a groove longitudinal for housing the long flexor proper of the first toe.
Le procédé d'obtention du dispositif d'appui tel que précité comprend l'étape consistant à mouler ce dispositif sur le pied de l'utilisateur ou sur une forme reproduisant ce pied.The process for obtaining the support device as mentioned above includes the step of molding this device on the foot of the user or on a form reproducing this foot.
De toute façon, l'invention sera bien comprise à l'aide de la
description qui suit, en référence au dessin schématique annexé
représentant, à titre d'exemple non limitatif, deux formes d'exécution
d'une semelle intérieure de chaussure :
La figure 1 représente une semelle, désignée par la référence générale 2, réalisée, par exemple, en un matériau thermoformable pour adopter la forme générale de la face inférieure d'un pied et assurer un support satisfaisant de celle-ci.Figure 1 shows a sole, designated by the reference general 2, made, for example, of a thermoformable material for adopt the general shape of the underside of a foot and ensure satisfactory support thereof.
Suivant l'invention et comme montré aux figures 1, 2 et 4,
cette semelle présente un élément de suspension 3 dans la zone destinée à
servir d'appui à l'extrémité distale de la première tête métatarsienne 6 du
pied. Cet élément de suspension 3 sert plus précisément à l'appui du
berceau phalango-bisesamoïdien 7 dans lequel s'articule la première tête
métatarsienne. Cet élément de suspension est réalisé en un matériau
souple à mémoire élastique, afin de reprendre rapidement sa forme initiale
après avoir été comprimé. L'épaisseur de l'élément de suspension est de
l'ordre de 3 à 6 mm. Compte tenu de sa souplesse, cet élément de
suspension ne nuit pas au confort de la chaussure équipée d'une telle
semelle.According to the invention and as shown in FIGS. 1, 2 and 4,
this sole has a
L'élément de suspension disposé sous la semelle peut être réalisé en EVA ou en polyéthylène, par exemple, dont les densités ont été indiquées précédemment.The suspension element arranged under the sole can be made of EVA or polyethylene, for example, whose densities have been indicated above.
La semelle représentée aux figures 1 à 3, qui est
particulièrement adaptée à l'équipement d'une chaussure pour la pratique
du golf, comprend également un élément de suspension transversal
médiotarsien 4 enveloppant la partie antérieure du talon sous l'axe médian
du pied, muni d'un prolongement 5 vers l'arrière du côté intérieur du talon.
Cet élément de suspension 4, 5 combiné à l'élément de suspension 3
favorise l'équilibre postural et le déplacement des hanches et oriente le
transfert de charge pendant le passage de l'éversion adaptative à
l'inversion de rigidification en assurant la mise en tension de l'aponévrose
plantaire par la dorsiflexion du gros orteil.The sole shown in Figures 1 to 3, which is

zone de freinage cinétique correspondante.It should be noted that the
Les figures 4 à 8 montrent une autre semelle dans laquelle les
mêmes éléments sont désignés par les mêmes références que
précédemment. Dans ce cas, l'élément de suspension 4, 5 est situé sur la
face supérieure de la semelle, et un élément amortisseur 9, connu en soi,
est disposé sous la semelle au niveau du talon.Figures 4 to 8 show another sole in which the
same elements are designated by the same references as
previously. In this case, the
Comme il va de soi, l'invention ne se limite pas à la seule forme d'exécution de cette semelle, décrite ci-dessus à titre d'exemple, elle en embrasse au contraire toutes les variantes. C'est ainsi notamment que ce dispositif d'appui du pied pourrait être non pas associé à une semelle intérieure de chaussure, mais au fond même de la chaussure, ou encore que les éléments de suspension pourraient être constitués par des zones suspendues de la semelle.It goes without saying that the invention is not limited to the single form of execution of this sole, described above by way of example, it on the contrary embraces all variants. This is how it foot support device could not be associated with a sole inside of the shoe, but at the very bottom of the shoe, or that the suspension elements could consist of zones suspended from the sole.
