- the central idea of the present invention is to improve the holding of the heel of the foot providing, at this level, a buttress, which is rigid and substantially non-flexible and a flexible buttress as defined in the claims. It is then the stiffness of the buttress which allows at the same time a satisfactory hold of the heel and a transmission of efforts. Furthermore, this construction allows flexibility of the sole. external in the so-called metatarsophalangeal area and a more natural course of the foot.
- the rigid buttress extends over at least one side of the shoe substantially up to the so-called metatarsophalangeal flexion zone. It results from the reinforcement of the rear part of the shoe, a satisfactory transmission forces from the user's leg to the front part of the foot, which is in contact permanent with the ground or the sliding support.
- the rigid buttress and essentially the rear part of the base of the foot surrounds the heel like a shell.
- This construction also allows a better transmission of forces, especially in transverse direction, thanks to the reinforcement and the hull shape of the rear part of the shoe, while keeping flexibility of the shoe in the metatarsophalangeal area.
- Said constructions allow better control of the ski by holding the heel and at the same time a general gain in energy and a direct transmission of forces by cancellation parasitic deformations of the sole and of the shoe, which deformations parasites are useless for propulsion by movements typical of sports above.

- the present invention applies also to all sports requiring a foot movement, such as for example snowshoeing, cross-country skiing, telemark skiing and hiking, and / or board sports such as snowboarding, ice skating, roller skating, ... etc.
- the following description is made with reference to a shoe for cross-country skiing.
- the shoe 1 shown comprises, in a known manner, a upper 2, a sole external 5 and an articulated collar 8, which is fixed to the rod by means of an axis 7.
- the construction of a shoe upper for cross-country skiing is well known in the art and will not be explained in detail in the description.
- the shoe 1 shown in Figures 1 and 2 is provided with a first rear buttress 13, in a material which is flexible enough to allow attachment by stitching of this flexible buttress 13 on the rod 2.
- the shoe 1 also has a second buttress 3, which is more rigid than the flexible buttress 13, and is in fact substantially non-flexible.
- This stiff buttress 3 surrounds heel 11 of shoe 1 with two walls respectively lateral 9 and medial 10, and by a rear wall at the heel 11.
- lateral wall, median respectively, each of the walls of said buttress is arranged outward and inward respectively of the foot or the shoe.
- the rigid buttress extends forward substantially up to zone 4 of flexion called metatarsophalangeal.
- the reinforcement of the shoe 1 via the rigid buttress 3 is therefore limited to an area between the heel 11 and said area 4 of metatarsophalangeal flexion.
- the user's foot is therefore well held on the side of the heel 11, while keeping flexibility of the shoe 1 in the metatarsophalangeal flexion zone 4, which allows an almost natural unfolding of the foot.
- the rigid buttress 3 has a maximum height which does not exceed that of the region located substantially below the ankle area 6, and is notably lower than the level of said area.
- the rigid buttress 3 rises substantially to the level of the ankle articulation zone and comprises the articulation axis 7 of the articulated collar 8.
- the maximum height of the buttress 3 is on the contrary more lower than the level of the hinge pin 7 which is therefore fixed only on the first buttress flexible 13, which allows more freedom in transverse direction at the collar due to the greater flexibility of the material.
- the maximum height of the buttress 3 is chosen so that the natural movement of the ankle 6 is not hampered.
- each of the walls 9, 10 decreases in height going towards the front of the buttress 2.
- each wall 9, 10 joins the upper edge 21 of the outer sole 3.
- the side wall 9 decreases in a substantially continuous manner forming a angle of approximately 45 ° with the upper edge 21 of the outer sole.
- the medial wall 10 can have the same shape.
- the side wall 9, as well as the wall medial 10 also decreases towards the rear, heel zone 11, for better comfort of the foot.
- the buttress 2 can form a stop 22 for the support of a loop 14 elastic which surrounds the back of the ankle 6 in the manner of a spur which provides a reminder elastic of the collar.
- This loop 14 is also known and does not constitute an element essential of the present invention. It is for this reason that loop 14 will not be described. in detail.
- the rigid buttress 3 is fixed, for example by gluing and / or riveting, to the flexible buttress 13, which presents it with sufficient flexibility allowing its connection, for example by bonding, stitching and / or riveting on the rod 2.
- the flexible buttress 13 also allows a certain stiff padding of the buttress 3, which avoids local pressure on the foot the user.
- the rigid buttress 3 only covers the flexible buttress 13 leaving uncovered an edge 23, which projects at least the upper edge 24 of the wall lateral of the rigid buttress 3, so as to facilitate its fixing or connection to the rod.
- the preferred materials of the rigid buttress 3 are plastics which can be reinforced with fibers, for example glass or carbon, and materials metal. In any case, all the materials are suitable, essentially guaranteeing almost non-flexibility of the rigid buttress 3.
- the preferred stiffness of the rigid buttress is between 260 MPa (Mega Pascal) which corresponds to the Modulus of elasticity Pebax 6333, and 200 GPa (Giga Pascal) which corresponds to the Modulus of elasticity of a composite fiberglass + carbon.
- the outer sole according to the embodiment shown in Figure 2 is made up of two parts, a front part 15 and a rear part 16.
- the front part 15 extends essentially from the front end 24 of shoe 1 to zone 4 of flexion metatarsophalangeal. This front part is flexible enough to allow a almost natural bending in said bending zone 4.
- the rear part 16 of the outer sole and the rigid buttress 3 form an assembly monobloc and preferably single material.
- This construction has advantages in that which relates to the mounting of the rear part 16 of the sole and of the rigid buttress 3 in one piece on the upper 2, the tightness of the rear lower part of the shoe 1, particularly in the area which traditionally represents the link between the outsole and buttress, and also with regard to further reinforcement improved, compared to the embodiment described with reference to FIG. 1, of the part rear and heel of the shoe 2.
- the rigid buttress 3 shown in FIG. 3 has the shape of a section shell transverse "U" shaped and completely surrounding the heel, namely as well laterally, at the rear than from below, and at a maximum height well below the level of the ankle area 6.
- the preferred height is between approximately 2 cm and 4 cm.

Abstract
Description
La présente invention concerne une chaussure destinée à coopérer avec un engin de glisse, notamment pour des sports exigeant un déroulement du pied, comme par exemple la raquette à neige, le ski de fond, style classique ou skate, le ski télémark et la randonnée, et/ou des sports de glisse comme par exemple le snowboard, le patin à glace et le patin à roulettes, à savoir des sports nécessitant une bonne transmission des efforts exercés par le pied pour une meilleure accroche, prise de carre.The present invention relates to a shoe intended for cooperate with a gliding device, especially for sports requiring a unfolding of the foot, such as snowshoeing, cross-country skiing, classic style or skateboarding, telemark skiing and hiking, and / or board sports such as snowboarding, ice skating and roller skating, namely sports requiring good transmission of the forces exerted by the foot for better grip, edge grip.
Dans tout les sports susmentionnés, il est nécessaire de transmettre les efforts provenant de la jambe de l'utilisateur par l'intermédiaire de la cheville, du pied à la zone de contact de la chaussure avec le support de glisse.In all the aforementioned sports, it is necessary to transmit the efforts from from the user's leg through the ankle, from the foot to the contact area of the shoe with the sliding support.
La transmission des efforts provenant de la jambe de l'utilisateur à la zone métatarso-phalangienne, qui représente la zone d'impulsion du pied par rapport au sol et/ou support, est une condition à satisfaire par une chaussure destinée aux sports susmentionnés. Pour éviter des pertes d'effort par amortissement et déformation parasite, il est indispensable de rigidifier la structure de base de la chaussure.Transmission of forces from the user's leg to the metatarsophalangeal area, which represents the pulse area of the foot relative to the ground and / or support, is a condition to be satisfied by a shoe intended for sports above. To avoid losses of effort by damping and parasitic deformation, it it is essential to stiffen the basic structure of the shoe.
En outre, il est important d'éviter tout mouvement du pied par rapport à la chaussure. Il en résulte notamment la condition d'une tenue satisfaisante du talon à l'intérieur de cette chaussure.In addition, it is important to avoid movement of the foot in relation to the shoe. he This results in particular in the condition of a satisfactory hold of the heel inside this shoe.
EP-A-0 651 953 dévoile une chaussure de glisse munie d'un contrefort.EP-A-0 651 953 discloses a sliding shoe provided with a buttress.
US-A-4 638 576 décrit la combinaison d'un contrefort rigide avec un élément flexible, mais uniquement dans le cas d'une chaussure d'athlétisme. US-A-4,638,576 describes the combination of a rigid buttress with a flexible element, but only in the case of an athletic shoe.
La présente invention a donc comme objectif de fournir une chaussure de conception améliorée qui remédie aux désavantages rencontrés dans l'art antérieur et qui concilie les exigences contradictoires, d'améliorer la tenue du talon tout en étant de construction simple et peu coûteuse.The present invention therefore aims to provide a shoe design which remedies the disadvantages encountered in the prior art and which reconciles conflicting requirements, to improve heel hold while being of simple and inexpensive construction.
L'idée centrale de la présente invention est d'améliorer la tenue du talon du pied prévoyant, à ce niveau, un contrefort, qui est rigide et sensiblement non flexible et un contrefort flexible tels que définis dans les revendications. C'est alors la rigidité du contrefort qui permet en même temps une tenue satisfaisante du talon et une transmission des efforts. Par ailleurs, cette construction permet une flexibilité de la semelle externe dans la zone dite métatarso-phalangienne et un déroulement plus naturel du pied.The central idea of the present invention is to improve the holding of the heel of the foot providing, at this level, a buttress, which is rigid and substantially non-flexible and a flexible buttress as defined in the claims. It is then the stiffness of the buttress which allows at the same time a satisfactory hold of the heel and a transmission of efforts. Furthermore, this construction allows flexibility of the sole. external in the so-called metatarsophalangeal area and a more natural course of the foot.
Selon un premier aspect de la présente invention, le contrefort rigide s'étend sur au moins un coté de la chaussure sensiblement jusqu'à la zone de flexion dite métatarso-phalangienne. Il résulte, du renforcement de la partie arrière de la chaussure, une transmission satisfaisante des efforts provenant de la jambe de l'utilisateur à la partie avant du pied, qui est en contact permanent avec le sol ou le support de glisse.According to a first aspect of the present invention, the rigid buttress extends over at least one side of the shoe substantially up to the so-called metatarsophalangeal flexion zone. It results from the reinforcement of the rear part of the shoe, a satisfactory transmission forces from the user's leg to the front part of the foot, which is in contact permanent with the ground or the sliding support.
Selon un deuxième aspect de la présente invention, le contrefort rigide et essentiellement la partie arrière de la base du pied entoure le talon à la manière d'une coque. Cette construction, elle aussi permet une meilleure transmission des efforts, notamment en direction transversale, grâce au renforcement et à la forme de coque de la partie arrière de la chaussure, tout en gardant une flexibilité de la chaussure dans la zone métatarso-phalangienne.According to a second aspect of the present invention, the rigid buttress and essentially the rear part of the base of the foot surrounds the heel like a shell. This construction, it also allows a better transmission of forces, especially in transverse direction, thanks to the reinforcement and the hull shape of the rear part of the shoe, while keeping flexibility of the shoe in the metatarsophalangeal area.
Lesdites constructions permettent un meilleur contrôle du ski par le tenue du talon et en même temps un gain général d'énergie et une transmission directe des efforts par annulation des déformations parasites de la semelle et de la chaussure, lesquelles déformations parasites sont inutiles pour la propulsion par les mouvements typiques des sports susmentionnés.Said constructions allow better control of the ski by holding the heel and at the same time a general gain in energy and a direct transmission of forces by cancellation parasitic deformations of the sole and of the shoe, which deformations parasites are useless for propulsion by movements typical of sports above.
De toute façon, l'invention sera mieux comprise et d'autres caractéristiques de celle-ci seront mises en évidence à l'aide de la description qui suit en référence au dessin schématiquement en représentant, à titre d'exemple non limitatif, plusieurs modes de réalisation et dans lequel :

Sur les figures 1 et 2 est représentée une chaussure 1 destinée à la pratique du ski de fond, particulièrement pour le style dit skate. Cependant, la présente invention s'applique également à tous les sports exigeant un déroulement du pied, comme par exemple la raquette à neige, le ski de fond, le ski télémark et la randonnée, et/ou des sports de glisse comme par exemple le snowboard, le patin à glace, le patin à roulettes,...etc. Pour des raisons de simplicité, la description suivante est effectuée en référence à une chaussure pour la pratique du ski de fond.In Figures 1 and 2 is shown a shoe 1 intended for the practice of cross-country skiing. background, particularly for the so-called skate style. However, the present invention applies also to all sports requiring a foot movement, such as for example snowshoeing, cross-country skiing, telemark skiing and hiking, and / or board sports such as snowboarding, ice skating, roller skating, ... etc. For some reasons of simplicity, the following description is made with reference to a shoe for cross-country skiing.
La chaussure 1 représentée comporte, d'une manière connue, une tige 2, une semelle
externe 5 et un collier articulé 8, qui est fixé à la tige par l'intermédiaire d'un axe
d'articulation 7. La construction d'une tige d'une chaussure pour la pratique de ski de fond
est bien connue dans l'état de technique et ne va pas être expliquée en détail dans la
description.The shoe 1 shown comprises, in a known manner, a upper 2, a sole
external 5 and an articulated
La chaussure 1 représentée sur les figures 1 et 2 est munie d'un premier contrefort arrière
13, en un matériau qui est assez souple pour permettre une fixation par piquage de ce
contrefort souple 13 sur la tige 2.The shoe 1 shown in Figures 1 and 2 is provided with a first
Selon la présente invention, la chaussure 1 présente en outre un second contrefort 3, qui
est plus rigide que le contrefort souple 13, et est en fait sensiblement non flexible. Ce
contrefort 3 rigide entoure le talon 11 de la chaussure 1 par deux parois respectivement
latérale 9 et médiale 10, et par une paroi arrière au niveau du talon 11. Par paroi latérale,
respectivement médiane, on entend chacune des parois dudit contrefort disposée
respectivement vers l'extérieur et vers l'intérieur du pied ou de la chaussure. Dans l'exemple
représenté, le contrefort rigide s'étend vers l'avant sensiblement jusqu'à la zone 4 de flexion
dite métatarso-phalangienne.According to the present invention, the shoe 1 also has a
Le renforcement de la chaussure 1 par l'intermédiaire du contrefort 3 rigide est donc
limité à une zone comprise entre le talon 11 et ladite zone 4 de flexion métatarso-phalangienne.
Le pied de l'utilisateur est donc bien tenu du côté du talon 11, tout en gardant
une flexibilité de la chaussure 1 dans la zone de flexion métatarso-phalangienne 4, ce qui
permet un déroulement quasi naturel du pied.The reinforcement of the shoe 1 via the
Le contrefort 3 rigide a une hauteur maximale qui n'excède pas celle de la région située
sensiblement au-dessous de la zone de cheville 6, et est notamment plus bas que le niveau
de ladite zone.The
Dans l'exemple de la figure 1, le contrefort 3 rigide monte sensiblement jusqu'au niveau
de la zone d'articulation de la cheville et comporte l'axe d'articulation 7 du collier articulé 8.In the example of FIG. 1, the
Dans l'exemple de la figure 2, la hauteur maximale du contrefort 3 est au contraire plus
basse que le niveau de l'axe d'articulation 7 qui n'est donc fixé que sur le premier contrefort
souple 13, ce qui permet d'avoir plus de liberté en direction transversale au niveau du collier
du fait de la plus grande souplesse du matériau.In the example of FIG. 2, the maximum height of the
De toute façon, le hauteur maximale du contrefort 3 est choisie de telle façon que le
mouvement naturel de la cheville 6 ne soit pas entravé. In any case, the maximum height of the
En partant de la zone au-dessous de la zone de cheville 6 représentant la hauteur
maximale en direction transversale du contrefort 2, chacune des parois 9, 10, décroít en
hauteur en allant vers l'avant du contrefort 2. A l'extrémité avant 12 du contrefort 2, chaque
paroi 9, 10, rejoint le bord 21 supérieur de la semelle externe 3. Dans l'exemple représenté
sur la figure 1, la paroi latérale 9 décroít d'une manière sensiblement continue en formant un
angle d'à peu près 45° avec le bord 21 supérieur de la semelle externe. La paroi médiale 10
peut avoir la même forme.Starting from the area below the
En partant de la zone au-dessous de la zone de cheville 6 représentant la hauteur
maximale en direction transversale du contrefort 2, la paroi latérale 9, de même que la paroi
médiale 10, décroít également vers l'arrière, zone de talon 11, pour un meilleur confort du
pied.Starting from the area below the
Par ailleurs, le contrefort 2 peut former une butée 22 pour l'appui d'un boucle 14
élastique qui entoure l'arrière de la cheville 6 à la manière d'un éperon qui fournit un rappel
élastique du collier. Cette boucle 14 est par ailleurs connue et ne constitue pas un élément
essentiel de la présente invention. C'est pour cette raison que la boucle 14 ne va être décrite
d'une manière détaillée.Furthermore, the
Etant donnée la rigidité du contrefort 3 rigide, qui peut rendre impossible une fixation du
contrefort 3 rigide directement sur le tissu et/ou cuir de la tige 2,
le contrefort 3 rigide est fixé, par exemple par collage et/ou rivetage, sur le contrefort souple
13, qui lui présente une flexibilité suffisante permettant sa liaison, par exemple par collage,
piquage et/ou rivetage sur la tige 2. Le contrefort 13 souple permet en outre un certain
rembourrage du contrefort 3 rigide, ce qui évite des pressions locales sur le pied de
l'utilisateur.Given the rigidity of the
Enfin, la structure en deux couches du contrefort 3, 13, confère à celui-ci une raideur
supplémentaire à la somme des deux raideurs individuelles par l'effet "lamellé-collé"
obtenu.Finally, the two-layer structure of the
De préférence le contrefort 3 rigide ne couvre le contrefort 13 souple que partiellement
en laissant découvert un bord 23, qui déborde au moins le bord supérieur 24 de la paroi
latérale du contrefort 3 rigide, de façon à faciliter sa fixation ou liaison sur la tige.Preferably the
Les matériaux préférés du contrefort 3 rigide sont des matières plastiques qui peuvent
être renforcées par des fibres, par exemple en verre ou en carbone, et des matériaux
métalliques. De toute façon, sont adaptés tous les matériaux garantissant essentiellement
une quasi non flexibilité du contrefort 3 rigide. La rigidité préférée du contrefort rigide est
comprise entre 260 MPa (Mega Pascal) ce qui correspond au Module d'élasticité Pebax
6333, et 200 GPa (Giga Pascal) ce qui correspond au Module d'élasticité d'un composite
fibre verre + carbone.The preferred materials of the
Outre la hauteur du contrefort rigide 3, la différence principale entre les chaussures des
figures 1 et 2 réside dans la construction de la semelle externe. Besides the height of the
En effet, la semelle externe selon le mode de réalisation représenté dans la figure 2 est
constituée en deux parties, une partie avant 15 et une partie arrière 16. La partie 15 avant
s'étend essentiellement de l'extrémité avant 24 de la chaussure 1 jusqu'à la zone 4 de flexion
métatarso-phalangienne. Cette partie 15 avant est suffisamment souple pour permettre une
flexion quasi naturelle dans ladite zone 4 de flexion.Indeed, the outer sole according to the embodiment shown in Figure 2 is
made up of two parts, a
La partie arrière 16 de la semelle externe et le contrefort 3 rigide forment un ensemble
monobloc et de préférence monomatière. Cette construction présente des avantages en ce
qui concerne le montage de la partie arrière 16 de la semelle et du contrefort 3 rigide en une
pièce sur la tige 2, l'étanchéité de la partie inférieure arrière de la chaussure 1,
particulièrement dans la zone qui représente de façon traditionnelle la liaison entre la
semelle externe et du contrefort, et également en ce qui concerne un renforcement encore
amélioré, par rapport au mode de réalisation décrit en référence à la figure 1, de la partie
arrière et du talon de la chaussure 2.The
Des constructions préférées du contrefort 3 rigide vont maintenant être décrites d'une manière détaillée en référence aux figures 3 et 4.Preferred constructions of the rigid buttress 3 will now be described in detail. in detail with reference to Figures 3 and 4.
Le contrefort 3 rigide représenté sur la figure 3 a la forme d'une coque de section
transversale en forme de "U" et entourant complètement le talon, à savoir aussi bien
latéralement, à l'arrière que par en-dessous, et a une hauteur maximale bien au-dessous du
niveau de la zone de cheville 6. La hauteur préférée est comprise entre environ 2 cm et 4
cm. Le mode de réalisation selon la figure 2, à savoir la construction monobloc de la partie
arrière de la semelle externe avec le contrefort 3 rigide, est symbolisée par des traits en
pointillé.The
Le contrefort 3 rigide représenté dans la figure 3 couvre entièrement la base du pied.
Bien entendu, le contrefort 3 pourrait aussi bien ne couvrir la partie de base du pied que
partiellement, par exemple en formant un creux ou un ou plusieurs évidements dans la partie
de base 17 du contrefort 3 rigide. De toute façon la construction du contrefort 3 rigide selon
l'exemple représenté dans la figure 3 permet un entourage du talon et de la partie arrière de
la base du pied à la manière d'une coque. En serrant un système de serrage, qui n'est pas
représenté dans les figures, et qui peut être constitué par exemple par un laçage, le pied est
pressé dans la coque formée par le contrefort 3 rigide et est alors bien tenu au talon.The
Comme il est représenté sur la figure 3, la paroi 9 latérale et/ou la paroi 10 médiale du
contrefort 3 rigide peuvent être pourvues d'évidements 18, ce qui permet une réduction du
poids du contrefort 3 rigide tout en gardant sa rigidité.As shown in FIG. 3, the
Dans l'exemple représenté dans la figure 4, le contrefort 3 rigide dépourvu de fond 17 et
muni de rebords 19 s'étend à partir des bords inférieurs respectivement de la paroi 9 latérale
et de la paroi 10 médiale, horizontalement vers l'intérieur. Ces rebords 19 transversaux
servent à la fixation du contrefort par intercalation entre une première de montage de la tige
2 et la semelle externe. En outre, ces rebords 19 transversaux participent à la rigidification
du contrefort 3 rigide, notamment en torsion. Bien entendu, ces rebords 19 transversaux
peuvent être prévus assez larges de telle sorte qu'ils se rejoignent presque en ne laissant
qu'une fente entre eux.In the example shown in FIG. 4, the rigid buttress 3 without
La paroi 9 latérale du contrefort 3 rigide, dans l'exemple représenté dans les figures, peut
s'étendre plus loin dans la direction longitudinale que la paroi 10 médiale en respectant
l'orientation de la ligne de flexion naturelle dans la zone 4 métatarso-phalangienne, qui
