Abstract

The boot sole consists of a front section (2) and a rear section (3) which covers at least the underside of the heel. The rear section is rigid, having a module of elasticity of 260 MPa to 200 GPa, and extends forwards as far as the metatarsal-phalangeal joint zone (5). The front and rear sections of the sole overlap where they join over a length (L) in or to the rear of the metatarsal-phalangeal joint zone. The front section has a connector for attaching to a ski and its lengthwise median axis lies at an angle to that of the rear section, while the latter can be made in one piece with a heel stiffener on the upper.

Description

La présente invention concerne une semelle, notamment une semelle externe pour une chaussure destinée à des sports exigeant un déroulement du pied et/ou à des sports de glisse. Elle concerne également un procédé de fabrication des semelles et une chaussure munie d'une telle semelle, respectivement une chaussure munie d'une semelle obtenue par ledit procédé de fabrication.The present invention relates to a sole, in particular an outer sole for a shoe intended for sports requiring a movement of the foot and / or for sliding sports. It also relates to a method of manufacturing soles and a shoe provided with such a sole, respectively a shoe provided with a sole obtained by said manufacturing process.

Comme mentionné ci-dessus, la présente invention est relative aux sports exigeant un déroulement du pied, comme par exemple la randonnée à pied, le ski de fond, skating ou classique, le ski alpin, le ski télémark ou la raquette à neige. Elle s'applique également aux sports de glisse, comme par exemple le patin à glace, le patin à roulette avec des roues en ligne ou non, le snowboard ou le skateboard.As mentioned above, the present invention relates to sports requiring an unrolling of the foot, such as for example hiking, cross-country skiing, skating or classic skiing, alpine skiing, telemark skiing or snowshoeing. It also applies to board sports, such as ice skating, roller skating with wheels in line or not, snowboarding or skateboarding.

Les sports susmentionnés ont en commun des exigences relatives à la chaussure et particulièrement à la semelle, lesquelles exigences, à première vue, sont incompatibles.The aforementioned sports have in common requirements relating to the shoe and particularly to the sole, which requirements, at first sight, are incompatible.

En fait, tout ces sports exigent des déplacements du centre de gravité de l'utilisateur de la zone de talon du pied de l'utilisateur à la zone de la flexion naturelle du pied dite métatarso-phalangienne et vice versa. Ces déplacements servent à la direction et/ou la propulsion du corps de l'utilisateur, par exemple par l'intermédiaire d'une prise de carre ou des opérations équivalentes, par exemple l'impulsion de mouvement pratiquée en faisant une foulée avec un patin à roulettes, ou du ski de fond que ce soit dans la technique classique ou de skating. Lesdits déplacements du centre de gravité sont accompagnés par une transmission des efforts dans la zone de talon, d'une part, et dans quelques cas d'une flexion dans ladite zone de flexion métatarso-phalangienne, d'autre part.In fact, all these sports require displacement of the user's center of gravity from the heel area of the user's foot to the area of the natural flexion of the foot called metatarsophalangeal and vice versa. These movements are used for the direction and / or propulsion of the body of the user, for example by means of an edge grip or equivalent operations, for example the impulse of movement practiced by making a stride with a skate on wheels, or cross-country skiing whether in the classic or skating technique. Said displacements of the center of gravity are accompanied by a transmission of forces in the heel zone, on the one hand, and in some cases of flexion in said metatarsophalangeal flexion zone, on the other hand.

Il en résulte l'exigence d'une bonne transmission des efforts, sans pertes par amortissement et déformation parasite dans la zone comprise au moins entre le talon et la zone métatarso-phalangienne, et par conséquent une exigence de rigidité de la semelle dans ladite zone, souvent accompagnée de l'exigence d'un déroulement aussi naturel que possible et par conséquence d'une souplesse associée de la semelle dans la zone métatarso-phalangienne.This results in the requirement of a good transmission of the forces, without losses by damping and parasitic deformation in the zone included at least between the heel and the metatarsophalangeal zone, and consequently a requirement of rigidity of the sole in said zone. , often accompanied by the requirement of a course as natural as possible and consequently of an associated flexibility of the sole in the metatarsophalangeal area.

Généralement, la semelle de chaussures de sport est formée d'une pièce. Pour faire varier la rigidité de la semelle dans la direction longitudinale, on fait généralement varier l'épaisseur de la semelle.Generally, the sole of sports shoes is formed in one piece. To vary the rigidity of the sole in the longitudinal direction, the thickness of the sole is generally varied.

Il est évident que l'intégration de deux exigences différentes et même incompatibles dans une pièce, à savoir la semelle, ne peut être effectuée qu'au détriment d'une de ces exigences, à savoir la transmission des efforts provenant de la jambe dans la zone comprise entre le talon et la zone métatarso-phalangienne et/ou la flexibilité dans la dernière zone.It is obvious that the integration of two different and even incompatible requirements in a part, namely the sole, can only be carried out at the expense of one of these requirements, namely the transmission of forces from the leg in the zone between the heel and the metatarsophalangeal zone and / or flexibility in the last zone.

Il en résulte le problème que ladite construction de la semelle ne peut pas satisfaire à toutes les exigences en même temps, et représente d'habitude un compromis non satisfaisant entre rigidité et souplesse.This results in the problem that said construction of the sole cannot meet all requirements at the same time, and usually represents an unsatisfactory compromise between stiffness and flexibility.

Un autre problème concerne la fabrication des semelles du type susmentionnées en une seule pièce. Ces semelles représentent des coûts de fabrication assez élevés car il est nécessaire de prévoir des semelles de longueurs spécifiques et différentes pour toutes les pointures désirées. Il en résulte la nécessité de fabriquer et stocker un grand nombre de semelles différentes ou de couper les bords d'une semelle pour fabriquer une pointure au-dessous. Cette dernière technique qui n'est utilisée que pour les semelles d'usure représente un gaspillage de matériau et ne diminue en réalité guère les coûts de production.Another problem relates to the manufacture of soles of the above type in one piece. These soles represent fairly high manufacturing costs because it is necessary to provide soles of specific and different lengths for all the desired sizes. This results in the need to manufacture and store a large number of different soles or to cut the edges of a sole to make a size below. This last technique which is only used for outsoles represent a waste of material and in reality does not reduce production costs.

Dans le document US 2 581 524, il est proposé de fabriquer une semelle intermédiaire en deux parties. Cependant, ladite semelle est destinée à une chaussure de loisir et en conséquence la partie arrière, bien qu'elle ait une rigidité plus élevée par rapport à la partie avant, reste flexible. La flexibilité et un certain amortissement de la partie arrière sont obtenus en la fabriquant en des matériaux comme le liège, sciure de bois ou latex. La semelle connue dudit document n'est par conséquent pas capable de transmettre des efforts destinés par exemple à une prise de cartes, et n'apporte donc pas de solution satisfaisante aux problèmes décrits au-dessus.In document US 2,581,524, it is proposed to manufacture an intermediate sole in two parts. However, said sole is intended for a leisure shoe and consequently the rear part, although it has a higher rigidity compared to the front part, remains flexible. The flexibility and a certain damping of the back part are obtained by manufacturing it in materials like cork, sawdust or latex. The known sole of said document is therefore not capable of transmitting forces intended for example for taking cards, and therefore does not provide a satisfactory solution to the problems described above.

La présente invention a comme objectif de proposer une semelle améliorée permettant de concilier les exigences contradictoires énoncées ci-avant et notamment une transmission améliorée des efforts et une flexibilité satisfaisante de la semelle tout en gardant des coûts de production modestes.The object of the present invention is to propose an improved sole making it possible to reconcile the contradictory requirements set out above and in particular an improved transmission of forces and a satisfactory flexibility of the sole while keeping production costs modest.

Elle a en outre comme objectif de proposer un procédé de fabrication pour une semelle et une chaussure munie d'un telle semelle, respectivement une chaussure munie d'une semelle obtenue par ledit procédé.It further aims to propose a manufacturing method for a sole and a shoe provided with such a sole, respectively a shoe provided with a sole obtained by said process.

L'idée centrale de la présente invention est de prévoir une semelle, notamment pour une chaussure de sport, en deux parties, une partie avant et une partie arrière adjacente à la partie avant.The central idea of the present invention is to provide a sole, in particular for a sports shoe, in two parts, a front part and a rear part adjacent to the front part.

Selon un premier aspect de la présente invention, la partie arrière est rigide et sensiblement non flexible. Cette caractéristique permet une transmission efficace des efforts provenant de la jambe de l'utilisateur et destinés à la direction et/ou propulsion du corps de l'utilisateur, notamment en permettant une prise de carre efficace ou pour coopérer avec un système de guidage de type arête de guidage en ski de fond.According to a first aspect of the present invention, the rear part is rigid and substantially non-flexible. This characteristic allows an efficient transmission of the forces coming from the user's leg and intended for the direction and / or propulsion of the user's body, in particular by allowing an efficient edge grip or for cooperating with a type guidance system. guide edge in cross-country skiing.

La partie arrière rigide s'étend de préférence dans la zone comprise entre le talon et la zone métatarso-phalangienne.The rigid rear part preferably extends in the zone between the heel and the metatarsophalangeal zone.

Selon un deuxième aspect de la présente invention, les deux parties constituant la semelle se chevauchent dans et/ou derrière la zone métatarso-phalangienne dans une zone de jonction de longueur réglable en fonction de la pointure. La variation de la longueur de chevauchement permet la fabrication de semelles de pointures différentes sur la base de parties arrière et avant respectivement identiques, ce qui réduit considérablement les coûts de production et de stockage par la diminution du nombre de pièces différentes devant être fabriquées.According to a second aspect of the present invention, the two parts constituting the sole overlap in and / or behind the metatarsophalangeal area in a junction area of adjustable length depending on the size. The variation in the overlap length allows the manufacture of soles of different sizes on the basis of rear and front parts respectively identical, which considerably reduces production and storage costs by reducing the number of different parts to be manufactured.

De toute façon, l'invention sera mieux comprise et d'autres caractéristiques de celle-ci seront mise en évidence à l'aide de la description qui suit en référence au dessin schématique annexé en représentant, à titre d'exemple non limitatif, plusieurs modes de réalisation et dans lequel :

  • la figure 1 est une vue de côté d'une semelle d'un premier mode de réalisation de la présente invention,
  • les figure 2a, 2b, sont des vues de côté d'une semelle selon un autre mode de réalisation de la présente invention,
  • la figure 3 est une vue latérale d'une chaussure intégrant une semelle selon la présente invention,
  • la figure 4 est une vue de dessous d'une semelle selon la présente invention.
In any case, the invention will be better understood and other characteristics thereof will be highlighted with the aid of the description which follows with reference to the appended schematic drawing showing, by way of nonlimiting example, several embodiments and in which:
  • FIG. 1 is a side view of a sole of a first embodiment of the present invention,
  • FIGS. 2a, 2b are side views of a sole according to another embodiment of the present invention,
  • FIG. 3 is a side view of a shoe incorporating a sole according to the present invention,
  • Figure 4 is a bottom view of a sole according to the present invention.

Sur la figure 1 est représentée, d'une manière schématique, une semelle externe 1 destinée à une chaussure pour la pratique de ski de fond. Cependant, la présente invention s'applique également à tous les sports exigeant une transmission des efforts provenant de la jambe de l'utilisateur et destinés à la direction et/ou la propulsion du corps de l'utilisateur, notamment par une opération généralement appelée prise de carres. Des exemples de telles disciplines de sports sont la raquette à neige, le ski de fond, le ski télémark, la randonnée à pied, le snowboard, le patin à glace ou le patin à roulettes. Pour des raisons de simplicité, la description suivante va être effectuée en référence à une semelle externe destinée à une chaussure pour la pratique de ski de fond.In Figure 1 is shown, schematically, an outer sole 1 for a shoe for the practice of cross-country skiing. However, the present invention also applies to all sports requiring transmission of forces from the user's leg and intended for the direction and / or propulsion of the user's body, in particular by an operation generally called grip. of edges. Examples of such sports disciplines are snowshoeing, cross-country skiing, telemark skiing, hiking, snowboarding, ice skating or roller skating. For reasons of simplicity, the following description will be made with reference to an outer sole intended for a shoe for cross-country skiing.

La semelle 1 représentée est constituée uniquement de deux parties 2, 3, qui sont adjacentes l'une à l'autre. La construction de la semelle 1 en deux parties 2, 3, a comme avantage, que chaque partie 2, 3, peut être conçue d'une manière optimale selon les exigences respectivement à satisfaire et de façon à pouvoir standardiser la production comme on le verra plus loin. La liberté de conception adaptée aux exigences particulières de chaque partie 2, 3, d'une manière indépendante de l'autre, se manifeste par exemple par la possibilité d'un choix de matériaux différents pour la partie 2 avant et la partie 3 arrière.The sole 1 shown consists only of two parts 2, 3, which are adjacent to each other. The construction of the sole 1 in two parts 2, 3 has the advantage that each part 2, 3 can be optimally designed according to the requirements respectively to be satisfied and so as to be able to standardize the production as will be seen further. The design freedom adapted to the particular requirements of each part 2, 3, independently of the other, manifests itself for example by the possibility of a choice of different materials for the part 2 front and the part 3 rear.

De préférence, la partie arrière 3 s'étend dans une zone comprise entre le talon 4 et la zone 5 de flexion naturelle dite métatarso-phalangienne.Preferably, the rear part 3 extends in an area between the heel 4 and the area 5 of natural flexion called metatarsophalangeal.

Comme il est représenté dans la figure 1, la partie avant 2 de la semelle 1 peut être munie d'un élément 6 d'accouplement, tel qu'un axe transversal, destiné à l'accouplement à un support de glisse tel qu'un ski de fond non représenté sur la figure. Ce support de glisse peut être par exemple un ski quelconque, un patin à glace ou à roulettes, un snowboard ou une raquette à neige.As shown in Figure 1, the front part 2 of the sole 1 may be provided with a coupling element 6, such as a transverse axis, intended for coupling to a sliding support such as a cross-country skiing not shown in the figure. This sliding support can be for example any ski, an ice or roller skate, a snowboard or a snowshoe.

La partie arrière 3 est de préférence rigide et sensiblement non flexible, ce qui évite des pertes par amortissement et déformations parasites et permet une meilleure transmission des efforts. La partie arrière 3 est réalisée en tout matériau garantissant une quasiment flexibilité de cette partie, et notamment en matière plastique de rigidité appropriée éventuellement renforcée par des fibres telles que verre ou carbone, ou des matériaux métalliques. Cette partie arrière aura de préférence un module d'élasticité compris entre 260 MPa (Mega Pascal) et 200 GPa (Giga Pascal).The rear part 3 is preferably rigid and substantially non-flexible, which avoids losses by damping and parasitic deformations and allows better transmission of forces. The rear part 3 is made of any material guaranteeing almost flexibility of this part, and in particular of plastic material of appropriate rigidity possibly reinforced by fibers such as glass or carbon, or metallic materials. This rear part will preferably have a modulus of elasticity between 260 MPa (Mega Pascal) and 200 GPa (Giga Pascal).

La partie avant 2, par contre, est de préférence flexible, de façon à permettre un déroulement aussi naturel que possible au pied. Cette caractéristique apporte des avantages vis à vis de l'utilisation pour des sports comme le ski de fond et la randonnée qui exigent un déroulement de la zone métatarso-phalangienne du pied.The front part 2, on the other hand, is preferably flexible, so as to allow the foot to be as natural as possible. This characteristic brings advantages with respect to the use for sports like cross-country skiing and hiking which require an unrolling of the metatarsophalangeal zone of the foot.

Cette partie avant 2 sera donc de préférence réalisée en matériau plastique présentant une flexibilité appropriée pour un tel déroulement du pied.This front part 2 will therefore preferably be made of plastic material having an appropriate flexibility for such an unwinding of the foot.

Les figures 2a, 2b et 4, illustrent un autre mode de réalisation de la présente invention, et en particulier le procédé de fabrication d'une semelle selon la présente invention.Figures 2a, 2b and 4 illustrate another embodiment of the present invention, and in particular the method of manufacturing a sole according to the present invention.

Comme montré sur les figures 2a, 2b, 4, la partie avant 2 et la partie arrière 3 de la semelle 1 se chevauchent sur une zone de jonction 5 de longueur "L" prédéterminée, cette longueur étant réglable en fonction de la pointure ainsi que cela sera expliqué plus loin. La zone de jonction ou de chevauchement s'étend de préférence dans et/ou derrière la zone de flexion métatarso-phalangienne.As shown in FIGS. 2a, 2b, 4, the front part 2 and the rear part 3 of the sole 1 overlap on a junction zone 5 of predetermined length "L", this length being adjustable as a function of the size as well as this will be explained later. The junction or overlap area preferably extends into and / or behind the metatarsophalangeal flexion area.

La limite avant extrême de la zone de chevauchement 5 est constituée par l'axe "Δ" d'articulation métatarso-phalangienne. Pour des raisons de progressivité, confort et afin d'assurer un meilleur déroulement du pied, sans rupture, la zone de chevauchement 5 aura de préférence une rigidité comprise entre celles de la partie arrière 3 et de la partie avant 2, voire même une rigidité allant en diminuant progressivement depuis sa zone de jonction avec la partie arrière, jusqu'à sa zone de jonction avec la partie avant pour une transition parfaite entre ces deux rigidités extrêmes.The extreme front limit of the overlap zone 5 is constituted by the axis "Δ" of metatarsophalangeal joint. For reasons of progressiveness, comfort and in order to ensure a better unrolling of the foot, without breaking, the overlap zone 5 will preferably have a rigidity comprised between those of the rear part 3 and of the front part 2, or even a rigidity gradually decreasing from its junction zone with the rear part, to its junction zone with the front part for a perfect transition between these two extreme rigidities.

Le procédé de fabrication d'une semelle selon la présente invention va maintenant être décrit en référence au figures 2a, 2b.The method of manufacturing a sole according to the present invention will now be described with reference to FIGS. 2a, 2b.

D'abord, comme première étape, on prévoit plusieurs parties avant 2 et plusieurs parties arrières 3, qui sont respectivement identiques et ont des formes correspondant sensiblement à la partie avant, respectivement arrière d'un pied humain. Cependant, les parties avant 2 et/ou arrière 3 pourraient également avoir une forme qui nécessite un découpage pour la finition de la semelle, à savoir une forme essentiellement rectangulaire.First, as a first step, several front parts 2 and several rear parts 3 are provided, which are respectively identical and have shapes corresponding substantially to the front part, respectively rear of a human foot. However, the front 2 and / or rear 3 parts could also have a shape which requires cutting for the finishing of the sole, namely an essentially rectangular shape.

Les parties avants 2 et les parties arrières 3 peuvent être formées en des matériaux différents. Un choix de matériaux différents facilite en outre la prévision de rigidités différentes, si désiré, des pièces avant 2 par rapport aux pièces arrières 3.The front parts 2 and the rear parts 3 can be formed from different materials. A choice of different materials also makes it easier to predict different stiffnesses, if desired, of the front pieces 2 compared to the rear pieces 3.

Comme deuxième étape, on aligne la partie avant 2 par rapport à la partie arrière 3 d'une manière chevauchante. Afin de mieux correspondre à la forme naturelle d'un pied humain et comme il est illustré dans la figure 4, les deux parties 2, 3, peuvent être alignées de telle sorte que leurs axes longitudinaux médians respectivement M-M' forment un angle correspondant à un angle de l'anatomie naturelle du pied au lieu d'être confondus.As a second step, the front part 2 is aligned with respect to the rear part 3 in an overlapping manner. In order to better correspond to the natural shape of a human foot and as illustrated in FIG. 4, the two parts 2, 3, can be aligned so that their median longitudinal axes respectively MM 'form an angle corresponding to a angle of the natural anatomy of the foot instead of being confused.

Comme troisième étape, on détermine la longueur respectivement "L1, L2" (cf. figures 2a, 2b) de chevauchement des deux parties 2, 3, de telle sorte que la longueur respectivement "P1, P2" (cf. figures 2a, 2b) effective de la semelle finie corresponde à la pointure désirée de la semelle, et par conséquent de la chaussure qui va être munie d'une telle semelle. Il est à noter que la différence entre deux pointures consécutives est généralement à peu près à 7mm. Ainsi, comme l'illustre bien la comparaison des figures 2a et 2b, un chevauchement sur une longueur "L1" plus grande permet d'obtenir une semelle d'une longueur totale "P1" plus petite et inversement.As a third step, the length respectively "L1, L2" is determined (cf. FIGS. 2a, 2b) of overlap of the two parts 2, 3, so that the length respectively "P1, P2" (cf. FIGS. 2a, 2b ) effective of the finished sole corresponds to the desired size of the sole, and consequently of the shoe which will be provided with such a sole. It should be noted that the difference between two consecutive sizes is generally around 7mm. Thus, as well illustrated by the comparison of FIGS. 2a and 2b, overlapping over a longer length "L1" makes it possible to obtain a sole with a shorter overall length "P1" and vice versa.

De préférence, une combinaison de certaines parties avant 2 identiques et parties arrière 3 identiques est utilisée pour la fabrication de semelles 1 dont la longueur "P" correspond à une gamme de deux à trois pointures. Cela se traduit par une réduction de moitié respectivement d'un tiers du stock de parties 2, 3, différentes. De préférence, la variation de la longueur "L" de chevauchement est donc égale à 14 respectivement 21mm.Preferably, a combination of certain identical front parts 2 and identical rear parts 3 is used for the manufacture of soles 1 whose length "P" corresponds to a range of two to three sizes. This results in a reduction by half respectively of a third of the stock of parts 2, 3, different. Preferably, the variation in the length "L" of overlap is therefore equal to 14 and 21mm respectively.

Il est à noter que, en faisant varier la longueur "L" de chevauchement, il est possible, grâce à la présente invention, de fabriquer des semelles selon un système de pointures continues, c'est-à-dire dont la gradation entre pointure soit aussi fine que désiré, sur la base d'un stock de parties 2, 3, constituant un système de gradation grossière.It should be noted that, by varying the length "L" of overlap, it is possible, thanks to the present invention, to manufacture soles according to a system of continuous sizes, that is to say of which the gradation between sizes is as fine as desired, based on a stock of parts 2, 3, constituting a coarse grading system.

De préférence, c'est la partie avant 2 qui chevauche la partie arrière 3. Cet arrangement présente particulièrement des avantages concernant la durabilité de la fixation de la partie avant 2 à la partie arrière 3, notamment lorsque la partie avant 2 présente une rigidité inférieure à celle de la partie arrière 3. Comme le montrent les figures 2a, 2b, l'extrémité avant 31 de la partie arrière 3 présente en direction longitudinale une section décroissante en biseau, de même que la partie arrière 21 de la partie avant 2. Ceci permet d'une part, un chevauchement des deux parties sans surépaisseur dans la zone de transmission, et d'autre part, de moduler la rigidité de la zone de transmission dans la direction longitudinale.Preferably, it is the front part 2 which overlaps the rear part 3. This arrangement has particularly advantages concerning the durability of the fixing of the front part 2 to the part rear 3, in particular when the front part 2 has a rigidity lower than that of the rear part 3. As shown in FIGS. 2a, 2b, the front end 31 of the rear part 3 has in longitudinal direction a decreasing bevel section, as well as the rear part 21 of the front part 2. This allows on the one hand, an overlap of the two parts without excess thickness in the transmission zone, and on the other hand, to modulate the rigidity of the transmission zone in the longitudinal direction.

Comme quatrième étape, on fixe la partie avant 2 par rapport à la partie arrière 3 d'une manière solidaire. Les moyens préférés de fixation sont le collage et le rivetage. Cependant, sont adaptés tous les moyens de fixation qui permettent une fixation solide, même sous des sollicitations en flexion ou torsion et sous des températures variables.As a fourth step, the front part 2 is fixed relative to the rear part 3 in an integral manner. The preferred means of attachment are bonding and riveting. However, all the fixing means are suitable which allow a solid fixing, even under bending or torsional stresses and under variable temperatures.

Comme résultat du procédé de fabrication selon la présente invention, on obtient une semelle d'une pointure désirée dans toute la gamme de tailles possibles sur la base de parties 2, 3, disponibles en nombre de tailles plus limité.As a result of the manufacturing process according to the present invention, a sole of a desired size is obtained in the whole range of possible sizes on the basis of parts 2, 3, available in a more limited number of sizes.

Un autre mode de réalisation de la présente invention est montré à la figure 3.Another embodiment of the present invention is shown in Figure 3.

Selon le mode de réalisation montré à la figure 3, la partie arrière 3 de la semelle 1 forme un ensemble monobloc avec un contrefort arrière 8 de la chaussure. Ledit contrefort 8 entoure le talon du pied à la manière d'une coque. De préférence, le contrefort 8 s'étend de la zone du talon 4 jusqu'à la zone 5 de flexion naturelle métatarso-phalangienne. L'effet de tenue, à la manière d'une coque, du talon du pied par l'ensemble monobloc formé par la partie 3 arrière de la semelle 1 et le contrefort 8 est nettement amélioré lorsque le contrefort 8 est sensiblement rigide, et d'une rigidité similaire à celle de la semelle. De préférence, la rigidité du contrefort 8 est quand même inférieure à la rigidité de la partie 3 arrière de la semelle 1, qui comme mentionné ci-dessus, est sensiblement non flexible.According to the embodiment shown in Figure 3, the rear part 3 of the sole 1 forms a one-piece assembly with a rear buttress 8 of the shoe. Said buttress 8 surrounds the heel of the foot in the manner of a shell. Preferably, the buttress 8 extends from the heel area 4 to the area 5 of natural metatarsophalangeal flexion. The holding effect, in the manner of a shell, of the heel of the foot by the one-piece assembly formed by the rear part 3 of the sole 1 and the buttress 8 is significantly improved when the buttress 8 is substantially rigid, and d '' a rigidity similar to that of the sole. Preferably, the rigidity of the buttress 8 is still less than the rigidity of the rear part 3 of the sole 1, which, as mentioned above, is substantially non-flexible.

Le choix de rigidités du contrefort 8 et de la partie arrière 3 de la semelle 1, respectivement, peut être effectué d'une manière optimale en formant le contrefort 8 et la partie arrière 3 de la semelle 1 en un même matériau ou au contraire en des matériaux différents, tout en gardant l'ensemble monobloc.The choice of stiffnesses of the buttress 8 and of the rear part 3 of the sole 1, respectively, can be made in an optimal manner by forming the buttress 8 and the rear part 3 of the sole 1 in the same material or, on the contrary, in different materials, while keeping the whole unit.

Les matériaux préférés pour le contrefort 8 sont le cuir ou des matériaux plastiques éventuellement renforcés par des inserts en matières métalliques ou des fibres de verre ou carbone.The preferred materials for the buttress 8 are leather or plastic materials possibly reinforced with inserts made of metallic materials or glass or carbon fibers.

La figure 4 est une vue de dessous représentant une semelle selon la présente invention. Comme représenté dans la figure et de façon à mieux correspondre à la forme naturelle d'un pied humain, les deux parties 2, 3, sont alignées de telle sorte que leurs axes longitudinaux médians M-M' forment un angle au lieux d'être confondus.Figure 4 is a bottom view showing a sole according to the present invention. As shown in the figure and so as to better correspond to the natural shape of a human foot, the two parts 2, 3, are aligned so that their median longitudinal axes M-M 'form an angle instead of being merged.

Selon le mode de réalisation représenté à la figure 4, la partie avant 2 de la semelle 1 comporte deux zones 11, 12, qui sont de préférence formées en des matériaux différents. La zone 11 constitue la zone "L" de chevauchement de la partie avant 2 de la semelle 1, comme indiqué auparavant cette zone de chevauchement 11 peut s'étendre vers l'avant jusqu'à l'axe "Δ" d'articulation métatarso-phalangienne. De préférence aussi, cette zone de chevauchement 11 présente une rigidité supérieure à celle de la zone avant 12 et qui est comprise entre la rigidité de la partie avant 2 et la rigidité de la partie arrière 3 de la semelle 1. Cette construction permet une fixation améliorée de la partie avant 2 à la partie arrière 3 en diminuant les différences de rigidité entre deux pièces adjacentes dans la zone "L" de chevauchement.According to the embodiment shown in Figure 4, the front part 2 of the sole 1 has two zones 11, 12, which are preferably formed from different materials. Zone 11 constitutes the zone "L" of overlap of the front part 2 of the sole 1, as indicated previously this zone of overlap 11 can extend forwards up to the axis "Δ" of metatarsal articulation -phalangeal. Also preferably, this overlap zone 11 has a rigidity greater than that of the front zone 12 and which is between the rigidity of the front part 2 and the rigidity of the rear part 3 of the sole 1. This construction allows attachment improved front part 2 to the rear part 3 by reducing the differences in rigidity between two adjacent parts in the overlapping area "L".

La zone 4 de talon de la partie 3 arrière de la semelle 1 est, notamment dans le cas d'une chaussure de ski de fond, munie d'une rainure 10 de guidage qui est apte à coopérer avec un dispositif en forme d'arête prévue sur un support de glisse, par exemple un ski de fond. Une telle rainure de guidage se prolonge également dans la partie avant 2 de la semelle. Il est à noter que la partie arrière 3 de la semelle 1 peut, selon son utilisation désirée, être munie d'un quelconque système coopérant avec un support de glisse et/ou un profilé pour une tenue et une prise de carres améliorées de la semelle 1 sur le sol.The heel zone 4 of the rear part 3 of the sole 1 is, in particular in the case of a cross-country ski boot, provided with a guide groove 10 which is able to cooperate with a device in the form of an edge provided on a sliding support, for example a cross-country ski. Such a guide groove also extends into the front part 2 of the sole. It should be noted that the rear part 3 of the sole 1 can, depending on its desired use, be provided with any system cooperating with a sliding support and / or a profile for improved grip and grip of the sole. 1 on the floor.

La partie avant 2 de la semelle 1 est, comme déjà décrit, munie d'un élément d'accrochage 6 pour une fixation articulée de l'avant de la chaussure munie de la semelle 1 sur un ski de fond. Il est à noter que la partie avant 2 peut aussi être munie d'un tout autre système de fixation coopérant avec un support de glisse ou de marche, comme par exemple un snowboard ou une raquette à neige.The front part 2 of the sole 1 is, as already described, provided with a hooking element 6 for an articulated fixing of the front of the boot provided with the sole 1 on a cross-country ski. It should be noted that the front part 2 can also be provided with any other fixing system cooperating with a sliding or walking support, such as for example a snowboard or a snowshoe.

Bien entendu, la précédente description a été effectuée à titre d'exemple non limitatif. Il est évident pour l'homme du métier que de nombreuses modifications peuvent être effectuées sans sortir de la portée de l'invention telle que définie par les revendications. Par exemple, une semelle selon la présente invention peut aussi bien comporter plus que deux parties constitutives, par exemple en divisant la partie arrière et/ou la partie avant en plusieurs sous-parties.Of course, the previous description has been made by way of nonlimiting example. It is obvious to those skilled in the art that many modifications can be made without departing from the scope of the invention as defined by the claims. For example, a sole according to the present invention may as well have more than two constituent parts, for example by dividing the rear part and / or the front part into several sub-parts.
