Abstract

The orthesis comprises a sole having an upper face (6) and a lower face, as well as an inner edge (8) and an outer edge (9), the said sole defining a heel zone (10), a plantar zone (11) and a toe zone (12). Its upper face (6) has, on the one hand, at the limit between the heel zone (10) and the plantar zone (11), a transverse projecting relief (4) forming an anchoring bar for the calcaneum (heel bone) of the foot of the user and, on the other hand, in the toe zone (6), in the vicinity of the inner edge (8) of the sole and in the immediate vicinity of the limit with the plantar zone (13), a depression (5) adapted to receive the first metatarsal head of the foot of the user.

Description

La présente invention concerne une orthèse podologique
destinée à être glissée dans une chaussure de sport ou, même
éventuellement, dans une chaussure de ville.The present invention relates to a podiatric orthosis
intended to be slipped into a sports shoe or, even
possibly in a city shoe.

Il s'agit, plus précisément, d'une semelle ayant une
face supérieure et une face inférieure, un bord intérieur et
un bord extérieur, ladite semelle définissant une zone
talonnière, une zone plantaire et une zone digitale.More specifically, it is a sole having a
upper side and a lower side, an inner edge and
an outer edge, said sole defining an area
heel, a plantar area and a digital area.

Lorsqu'un athlète court, il attaque généralement le sol du talon. Il passe ensuite de la position taligrade à la position plantaire avec un risque qu'à ce stade, son pied parte "en interne" ou "en externe". De la position plantigrade, il passe à la position digitigrade en venant en appui sur les têtes métatarsiennes. Du fait que la première tête métatarsienne est très proéminente par rapport aux autres, elle ne trouve pas sa place dans une semelle ou chaussure classique : il s'ensuit un glissement du pied en externe et une contraction des orteils, créant un déséquilibre. When an athlete runs, he usually attacks the heel floor. He then passes from the taligrade position to the plantar position with a risk that at this stage, his foot will go "internally" or "externally". From the plantigrade position, it passes to the digitigrade position while coming to bear on the metatarsal heads. Because the first metatarsal head is very prominent compared to the others, it does not find its place in a conventional sole or shoe: it follows a sliding of the foot externally and a contraction of the toes, creating an imbalance.

La présente invention a pour but de remédier à ces inconvénients en apportant une orthése adaptée à éviter au pied toute dérive latérale. The present invention aims to remedy these drawbacks by providing an orthosis adapted to avoid any lateral drift at the foot.

Ce but est atteint en ce sens que, dans l'orthèse selon l'invention, la face supérieure de la semelle présente, d'une part, à la limite entre la zone talonnière et la zone plantaire, un relief transversal en saillie formant barre d'ancrage pour le calcaneum du pied de l'utilisateur et, d'autre part, dans la zone digitale, au voisinage du bord intérieur de la semelle et à proximité immédiate de la limite avec la zone plantaire, une dépression adaptée à accueillir la première tête métatarsienne du pied de l'utilisateur. This object is achieved in the sense that, in the orthosis according to the invention, the upper face of the sole has, on the one hand, at the limit between the heel area and the plantar area, a transverse protruding relief forming a bar anchor for the calcaneum of the user's foot and, on the other hand, in the digital zone, in the vicinity of the inner edge of the sole and in the immediate vicinity of the limit with the plantar zone, a depression adapted to accommodate the first metatarsal head of the user's foot.

La barre d'ancrage du calcaneum stabilise le pied dans l'axe longitudinal et évite qu'il parte en interne ou externe, pendant le passage de la position taligrade à la position plantigrade. De son côté, la dépression, en accueillant la première tête métatarsienne, permet au premier rayon de rester dans l'axe, lors du passage en position digitigrade, apportant ainsi une meilleure stabilité au pied. The calcaneum's anchor bar stabilizes the foot in the longitudinal axis and prevents it from leaving internally or externally, during the transition from the taligrade position to the plantigrade position. For its part, the depression, by welcoming the first metatarsal head, allows the first ray to remain in the axis, when passing into the digitigrade position, thus bringing better stability to the foot.

Dans une forme d'exécution de l'invention, la face inférieure de la semelle est constituée d'une coque de matière semi-rigide. In one embodiment of the invention, the underside of the sole consists of a shell of semi-rigid material.

Comme on le sait, lors de l'attaque du sol par le
talon, des chocs nuisibles remontent du sol et, pour y
remédier, la zone talonnière de ladite coque présente un
évidement grossièrement circulaire et garni d'un matériau
amortissant.As we know, during the ground attack by the
heel, harmful shocks rise from the ground and, to
remedy, the heel area of said shell has a
roughly circular recess and filled with a material
cushioning.

Cet évidement pourra avoir un rayon variant entre 5 et
6,5 cm et il sera garni d'un matériau élastomère, viscoélastique, polyuréthane, etc.This recess may have a radius varying between 5 and
6.5 cm and it will be filled with an elastomeric, viscoelastic, polyurethane material, etc.

La garniture amortissante sera insérée et moulée dans
la coque semi-rigide, sans former de surépaisseur de sorte
qu'elle n'entraînera pas d'instabilités latérales.The cushioning pad will be inserted and molded into
the semi-rigid shell, without forming any extra thickness so
that it will not cause lateral instabilities.

La face supérieure de la semelle selon l'invention est constituée, pour ce qui est de la zone digitale, de la face supérieure de la coque semi-rigide et, pour ce qui est des zones plantaire et talonnière, d'un matériau rigide. The upper face of the sole according to the invention consists, as regards the digital zone, of the upper face of the semi-rigid shell and, as regards the plantar and heel zones, of a rigid material.

La face supérieure de la semelle est, quant à elle,
recouverte d'une matière absorbante.The upper side of the sole is
covered with absorbent material.

La semelle selon l'invention présente, en ~~outre,
avantageusement, le long du bord interne de la zone
plantaire, une partie relevée formant butée
sous-astragalienne.The sole according to the invention has, in addition,
advantageously, along the internal edge of the zone
plantar, a raised part forming a stop
subtalar.

L'invention est décrite ci-après en détail par
référence aux dessins annexés dans lesquels
- la figure 1 montre la direction suivie par les appuis
successifs du pied d'un athlète pendant la course,
- la figure 2 est une vue de dessus de l'orthèse selon
l'invention,
- la figure 3 est une vue de dessous correspondant à la
figure 2,
- la figure 4 est vue latérale interne de l'orthèse des figures 2 et 3,
- la figure 5 est une vue latérale externe de cette même orthose,
- la figure 6 est une coupe prise le long de la ligne Vi-Vi de la figure 2.The invention is described below in detail by
reference to the accompanying drawings in which
- Figure 1 shows the direction followed by the supports
successive feet of an athlete during the race,
- Figure 2 is a top view of the orthosis according
the invention,
- Figure 3 is a bottom view corresponding to the
figure 2,
FIG. 4 is an internal lateral view of the orthosis of FIGS. 2 and 3,
FIG. 5 is an external lateral view of this same orthosis,
- Figure 6 is a section taken along the line Vi-Vi in Figure 2.

Si l'on examine tout d'abord la figure 1, la flèche F indique la direction des appuis successifs du pied de l'utilisateur, dont le squelette est figuré. Tout d'abord le contact avec le sol se fait, en 1, au niveau du côté externe du talon (position taligrade), puis, en 2, à un niveau sensiblement médian de la plante du pied (position plantigrade), et enfin, en 3, où le pied prend appui sur la première tête métatarsienne près du bord interne de la semelle (position digitigrade!. If we first examine Figure 1, the arrow F indicates the direction of successive presses of the user's foot, whose skeleton is depicted. First of all, the contact with the ground is made, in 1, at the level of the external side of the heel (taligrade position), then, in 2, at a substantially median level of the sole of the foot (plantigrade position), and finally, in 3, where the foot rests on the first metatarsal head near the internal edge of the sole (digitigrade position !.

En 4 et 5 sont respectivement schématisées la barre d'ancrage du calcanéum et la dépression d'accueil de la première tête mêtatarsienne qui constituent les caractéristiques essentielles de l'orthèse selon l'invention. In 4 and 5 are respectively shown the anchor bar of the calcaneus and the depression of reception of the first metatarsal head which constitute the essential characteristics of the orthosis according to the invention.

Comme il ressort des figures 2 à 6, l'orthèse ou semelle présente une face supérieure 6, une face inférieure 7, un bord interne 8 et un bord externe 9. As can be seen in FIGS. 2 to 6, the orthosis or sole has an upper face 6, a lower face 7, an internal edge 8 and an external edge 9.

La semelle comporte, de droite à gauche sur le dessin, une zone talonnière 1#, une zone plantaire il et une zone digitale 12. Au niveau de la jonction entre la zone talonnière 1# et la zone plantaire 11, la semelle selon l'invention comporte un relief transversal 4 saillant à la surface supérieure de la semelle. Ce relief forme barre d'ancrage pour le calcaneum. Par ailleurs, au voisinage du bord interne 8 et de la jonction entre la zone plantaire il et la zone digitale 12, la face supérieure de ladite zone digitale présente une dépression 5 adaptée à recevoir la première tête métatarsienne. The sole comprises, from right to left in the drawing, a heel area 1 #, a plantar zone il and a digital zone 12. At the junction between the heel zone 1 # and the plantar zone 11, the sole according to the invention comprises a transverse relief 4 projecting from the upper surface of the sole. This relief forms an anchor bar for the calcaneum. Furthermore, in the vicinity of the internal edge 8 and of the junction between the plantar zone 11 and the digital zone 12, the upper face of said digital zone has a depression 5 adapted to receive the first metatarsal head.

La semelle comporte en outre, le long d-u bord interne 8 de la zone plantaire 11, une partie relevée 13 formant butée sous-astragalienne.  The sole further comprises, along the internal edge 8 of the plantar zone 11, a raised portion 13 forming a subtalar abutment.

Comme il ressort de la figure 6, la face inférieure de la semelle est constituée d'une coque en un premier matériau 14 qui présente, dans la zone talonnière, un évidement ou une découpe 15 obturée par un second matériau 16. Le premier matériau est semi-rigide et le second matériau possède des propriétés amortissantes. Comme on le voit, la garniture de matériau amortissant 16 ne forme aucune surépaisseur dans la semelle. La face supérieure de la semelle est constituée, dans la zone digitale, par la face supérieure de la coque semi-rigide 14 et, dans les zones plantaire et talonnière, par un troisième matériau 17 qui est rigide. La partie avant de la semelle est donc relativement souple, tandis que les parties centrale et arrière sont rigides. Une couche de matériau absorbant 18 recouvre la face supérieure de la semelle. Ce matériau peut être constitué de mousse néoprène, de mousse réticulée ou de tout autre matériau pouvant contribuer à améliorer l'énergie cinétique du sujet en déplacement. As can be seen from FIG. 6, the underside of the sole consists of a shell of a first material 14 which has, in the heel area, a recess or a cutout 15 closed by a second material 16. The first material is semi-rigid and the second material has damping properties. As can be seen, the cushioning of damping material 16 does not form any additional thickness in the sole. The upper face of the sole is formed, in the digital area, by the upper face of the semi-rigid shell 14 and, in the plantar and heel areas, by a third material 17 which is rigid. The front part of the sole is therefore relatively flexible, while the central and rear parts are rigid. A layer of absorbent material 18 covers the upper face of the sole. This material can be made of neoprene foam, cross-linked foam or any other material that can help improve the kinetic energy of the moving subject.

Comme on le voit, l'usage du matériau amortissant 16 est limité, selon l'invention, à la zone talonnière et en tant que sous-couche. De ce fait, il n'amortit pas l'énergie cinétique comme le font les matériaux amortissants appliqués sur toute la surface de la semelle. As can be seen, the use of the cushioning material 16 is limited, according to the invention, to the heel area and as an underlay. Therefore, it does not absorb kinetic energy as do the shock absorbing materials applied to the entire surface of the sole.

L'orthèse selon l'invention est adaptée à prévenir et à traiter certaines pathologies, telles que les tendinites, fractures de fatique, entorses, etc. fréquentes chez les sportifs, ces problèmes ayant une cause commune, à savoir l'instabilité du pied dans la chaussure, à laquelle remédie l'invention.  The orthosis according to the invention is suitable for preventing and treating certain pathologies, such as tendinitis, fractures of the fatigue, sprains, etc. frequent in athletes, these problems having a common cause, namely the instability of the foot in the shoe, which the invention remedies.
