Definitions
- the present invention relates to an alpine ski boot which has a shell base provided with an outer sole and surmounted by a rod, the latter being provided with a central and / or anterior opening for the passage of the foot of a skier. and forming at its upper part a collar intended to enclose the lower leg by means of at least one tensioning member disposed on transverse flaps, produced on either side of the opening of the rod and co-operating in closing by mutual recovery under the action of said tensioning member.
- the problems generally encountered are constituted by the search for a compromise between a shell base having qualities of resistance to torsion for good conduct of the ski, thanks to a rear support and lateral supports, and a rod benefiting from sufficiently flexible parts able to lend themselves, that is to say to allow the adaptability of its parts to the individual aspects of the morphology of the skier's foot.
- the ski boot has a shell base provided with an outer sole and surmounted by a rod provided with a central and anterior opening for the passage of a skier's foot; this rod forms at its upper part a collar intended to enclose the lower leg by means of at least one tensioning member disposed on transverse flaps produced on either side of the opening of said rod and intended to cooperate in closing by mutual recovery under the action of said tensioning member.
- the solution to solving the problem of the sealing of the transverse flaps that is to say the overlapping parts, consists in adding a flexible waterproof cover means on the outside of the shoe to wrap the two flaps by closing the gap remaining between them in shoe closed position.
- a shoe should be easy to put on by having a zone for introducing the foot, which is wide and easy to access and capable of conforming to the foot to be held and / or tightened.

- Such a construction proves to be complex to carry out because it requires numerous parts which are to be assembled and adjusted on the shell base and does not simplify the structure of the rod in the zone corresponding to the lower leg of the skier.
- the invention aims to remedy all these drawbacks by proposing a ski boot, of the central entry type and / or from the front known as "variable volume", which is of extremely simplified construction, easy to put on and take off, easily adjustable on the lower leg and the skier's foot, and waterproof. Also, the object of the invention is to provide such a boot which is rigid laterally for good transmission of the skier's support on the upper of the boot, and relatively flexible in the longitudinal direction of the latter to elastically control in effort and / or in amplitude of displacement, the front and / or rear supports of said skier.
- the invention relates to the extremely simplified embodiment of an alpine ski boot obtained from a shell base provided with an outer sole and surmounted by a rod, provided with a central and / or anterior opening for the passage of a skier's foot, which forms a collar at its upper part intended to enclose the lower leg by means of at least one tensioning member disposed on transverse flaps, produced on either side of the opening of the rod and intended to cooperate in closing by mutual overlap, under the action of said tensioning organ.
- the ski boot is characterized in that it consists of two main parts which consist on the one hand of the shell base longitudinally open at its upper part and made of a relatively rigid material and on the other hand of a single cover-closure element attached and fixed on the periphery of the upper longitudinal opening of said shell base, this element having itself and in one piece a first substantially vertical part forming the rod enclosing the lower leg by means of the collar and a second substantially horizontal part obtained as an extension of the first and forming an upper foot-holding cover, the assembly thus formed being obtained in a material relatively less rigid than that of the shell base.
- the present invention also relates to the characteristics which will emerge during the description which follows, and which should be considered in isolation or according to all their possible technical combinations.
- the shoe 1 designated as a whole in FIG. 1 has an outer sole 2 and a shell base 3 surmounted by a rod 4 provided, on its upper part with an opening 5, central and / or anterior, to allow the passage of the skier's foot.
- the rod 4 forms, in this upper part, a collar 6 intended to enclose the lower leg by means of at least one tensioning member 7, disposed on transverse flaps 10, ie 10c, 10d, 10e, which will be described in more detail, further.
- the opening of the upper 4 takes place towards the front of the shoe 1, but of course the invention is not limited thereto.
- Said flaps 10 are consequently produced on either side of the front opening of the rod 4 and are intended to cooperate in closing by mutual overlap, under the action of the tensioning members 7.
- the shoe 1 consists of two main parts which consist on the one hand of the shell base 3 longitudinally open 11 at its upper part and made of a relatively rigid material and on the other hand '' a single cover-closure element 12 attached and fixed on the periphery 11a of the upper longitudinal opening 11 of said shell base 3, this element 12 having itself and in one piece a first substantially vertical part forming the rod 4 enclosing the lower leg via the collar 6 and a second substantially horizontal part 13 obtained as an extension of the first and forming an upper foot support cover, the assembly thus formed being obtained from a relatively less material rigid than that of the hull base 3.
- the part 13 of the cover-closure element 12 forming the upper foot-holding cover covers the corresponding longitudinal opening 11 of the shell base 3 by forming at least two adjacent transverse flaps 10, ie 10a, 10b , arranged on either side of the longitudinal axis of the shell base 3 and provided with a plurality of tensioning members 7 located opposite and acting on said flaps 10 in transverse direction.
- the longitudinal opening 11 of the shell base 3 extends almost over the entire length of the latter from a front zone close to its tip 14 and along a width such as to determine a large entry opening of foot.
- transverse flaps 10 of the covering element 12, ie 10a and 10b overlap one another and extend continuously from one another, at least in the region of the cover. upper 13 for holding the foot, forming between them a fold 15 in the manner of a bellows in order to ensure a permanent seal of the shoe 1, including when the said flaps 10a and 10b are separated to give passage to the foot during putting on or taking off.
- transverse flaps 10c, 10d, 10e of the collar 6 are obtained by separate cutting and reciprocally overlap each other at their free edges directed towards the longitudinal axis of the opening 5 at least in the upper area of the rod 4.
- the flaps 10c and 10d are arranged on the same side of the collar 6 and are intended to cooperate with a single flap 10e located on the other side.
- the cover-closure element 12 forming both the rod 4 and the upper foot support cover 13 is attached. and fixed on the periphery 11a of the upper longitudinal opening 11 of the shell base 3, by means of fixing points 16 capable of connecting together two peripheral connection zones A and B arranged in superposition, and respectively constituting the lower periphery of the cover-closure element 12 and the upper periphery of the shell base 3.
- connecting zones A and B have the particularity of having relatively smaller thicknesses than that of the cover-closure element 12 and of the shell base 3 proper, themselves also of different rigidities, as already mentioned above.
- the attachment points 16 of the cover-closure element 12 relative to the shell base 3 are preferably arranged on the front periphery of the horizontal part of said element forming the upper cover 13 for holding the foot, from two articulation axes 17 located at the malleoli of the skier's foot in order to allow their relative pivoting with respect to each other, by an effect of elastic flexibility of the rod 4 relative to the upper cover 13 for holding foot, the posterior zone thereof extending beyond the hinge axes 17 and being devoid of attachment points 16 relative to the shell base 3.
- the fixing points 16 are constituted by rivets, but it is obvious that they could be replaced by any other known means of assembly such as, for example, by a respective gluing of the zones A and B in a also anterior part of the peripheries of the element 12 and the opening 11 of the shell base 3, from the same articulation axes 17.
- the shell base 3 is extended at its rear end 3a, corresponding to its heel, by a relatively rigid vertical extension 18 extending above the skier's ankle towards the base of his calf, over a height h corresponding substantially to two thirds of the total height H of the boot 1, covering at least partially the lateral zones of the skeleton's malleoli.
- the shoe 1 consists of two thirds of rigid part (the shell base 3) and one third of flexible part (the collar 6).

- the rod 4 is thus blocked rearward and offers the skier firm support for his anteroposterior balance.
- the rear vertical extension 18 of the shell base 3 preferably comprises two edges 20 of lateral support extending behind the pivot axes 17 and capable of cooperating with corresponding parts of the rod 4.
- the shoe 1 can also be provided with means 21 for limiting the amplitude of the possible pivoting of the upper 4 relative to the shell base 3 and relative to the upper cover 13 for holding the foot.

Abstract
Description
La présente invention concerne une chaussure de ski alpin qui présente une base de coque munie d'une semelle externe et surmontée d'une tige, cette dernière étant pourvue d'une ouverture centrale et/ou antérieure pour le passage du pied d'un skieur et formant à sa partie supérieure un collier destiné à enserrer le bas de jambe par l'intermédiaire d'au moins un organe tendeur disposé sur des rabats transversaux, réalisés de part et d'autre de l'ouverture de la tige et venant coopérer en fermeture par recouvrement mutuel sous l'action du dit organe tendeur.The present invention relates to an alpine ski boot which has a shell base provided with an outer sole and surmounted by a rod, the latter being provided with a central and / or anterior opening for the passage of the foot of a skier. and forming at its upper part a collar intended to enclose the lower leg by means of at least one tensioning member disposed on transverse flaps, produced on either side of the opening of the rod and co-operating in closing by mutual recovery under the action of said tensioning member.
Dans ce type de chaussure, les problèmes généralement rencontrés sont constitués par la recherche d'un compromis entre une base de coque ayant des qualités de résistance à la torsion pour une bonne conduite du ski, grâce à un appui arrière et des appuis latéraux, et une tige bénéficiant de parties suffisamment souples aptes à se prêter, c'est-à-dire à autoriser l'adaptabilité de ses parties aux aspects individuels de la morphologie du pied du skieur.In this type of boot, the problems generally encountered are constituted by the search for a compromise between a shell base having qualities of resistance to torsion for good conduct of the ski, thanks to a rear support and lateral supports, and a rod benefiting from sufficiently flexible parts able to lend themselves, that is to say to allow the adaptability of its parts to the individual aspects of the morphology of the skier's foot.
La construction d'une chaussure de ce type est enseignée par le brevet français n°2022109. Sa structure présente une base de coque rigide munie d'une semelle externe, une tige fixée rigidement sur celle-ci qui forme à sa partie supérieure un collier destiné à enserrer le bas de jambe par l'intermédiaire d'un organe tendeur et des parties extensibles élastiquement. Ces parties sont disposées en avant et en arrière de la tige pour, également, permettre et faciliter le passage du pied au chaussage - déchaussage. Un capot de fermeture supérieur antérieur constitue une partie se prêtant sur le dessus du pied, et des moyens de contrôle de la flexion, par exemple une bande élastique pourvue de ressort, sont associés à la tige.The construction of a shoe of this type is taught by French patent n ° 2022109. Its structure has a rigid shell base provided with an external sole, a rod rigidly fixed thereon which forms at its upper part a collar intended to grip the lower leg by means of a tensioning member and parts elastically extensible. These parts are arranged in front of and behind the upper to, also, allow and facilitate the passage of the foot to the boot - heaving. An anterior upper closure cover constitutes a part which lends itself to the top of the foot, and means for controlling flexion, for example an elastic band provided with a spring, are associated with the rod.
Une telle chaussure se révèle:
- très compliquée car elle fait appel à de nombreux composants, en fait au moins quatre,
- peu aisée à chausser-déchausser car elle nécessite la libération préalable des moyens de contrôle de la flexion et de l'organe tendeur,
- d'un ajustement peu précis sur le pied car elle utilise des moyens extensibles pour couvrir les parties du dessus du pied, du bas de jambe et du talon, l'organe tendeur recouvrant partiellement ces moyens ne pouvant qu'être sujet à provoquer des zones de pression localisées donc douloureuses
- peu fonctionnelle car la tige ne peut pas pivoter par rapport à la base de coque
- peu étanche car de grandes parties de recouvrement et d'enveloppement du pied sont des garnitures textiles, et présentent de nombreuses jointures.
- very complicated because it uses many components, actually at least four,
- not very easy to put on and take off because it requires the prior release of the flexion control means and of the tensioning member,
- of an imprecise adjustment on the foot because it uses extensible means to cover the parts of the top of the foot, the lower leg and the heel, the tensioning member partially covering these means can only be liable to cause zones pressure localized so painful
- not very functional because the rod cannot pivot relative to the shell base
- not very waterproof because large parts of covering and wrapping of the foot are textile linings, and have many joints.
Ce dernier inconvénient tend à être résolu par le brevet français n°2691884 déposé par la demanderesse. Selon ce brevet, la chaussure de ski présente une base de coque munie d'une semelle externe et surmontée d'une tige pourvue d'une ouverture centrale et antérieure pour le passage du pied d'un skieur ; cette tige forme à sa partie supérieure un collier destiné à enserrer le bas de jambe par l'intermédiaire d'au moins un organe tendeur disposé sur des rabats transversaux réalisés de part et d'autre de l'ouverture de ladite tige et destinés à coopérer en fermeture par recouvrement mutuel sous l'action dudit organe tendeur. La solution pour résoudre le problème de l'étanchéité des rabats transversaux, soit des parties en recouvrement, consiste à rapporter un moyen de couverture souple étanche sur l'extérieur de la chaussure pour envelopper les deux rabats en fermant l'interstice subsistant entre eux en position de fermeture de la chaussure.This last drawback tends to be resolved by French patent n ° 2691884 filed by the plaintiff. According to this patent, the ski boot has a shell base provided with an outer sole and surmounted by a rod provided with a central and anterior opening for the passage of a skier's foot; this rod forms at its upper part a collar intended to enclose the lower leg by means of at least one tensioning member disposed on transverse flaps produced on either side of the opening of said rod and intended to cooperate in closing by mutual recovery under the action of said tensioning member. The solution to solving the problem of the sealing of the transverse flaps, that is to say the overlapping parts, consists in adding a flexible waterproof cover means on the outside of the shoe to wrap the two flaps by closing the gap remaining between them in shoe closed position.
Ce type de construction donne un résultat satisfaisant mais se révèle complexe et coûteux, car il nécessite de rapporter un moyen d'étanchéité sur les rabats et ne simplifie pas la conception de la base de coque et de la tige lesquelles, doivent comporter des amincissements de paroi à l'endroit des rabats pour faciliter leur écartement lors du chaussage - déchaussage et leur adaptation sur le dessus du pied et autour du bas de jambe lors de la fermeture de la chaussure.This type of construction gives a satisfactory result but turns out to be complex and costly, because it requires fitting a sealing means on the flaps and does not simplify the design of the shell base and of the rod which must include thinnings of wall at the location of the flaps to facilitate their spacing when putting on - heaving and fitting them on the top of the foot and around the lower leg when the shoe is closed.
En fait, il a toujours été souhaité qu'une chaussure soit aisément chaussable en présentant une zone d'introduction du pied, qui soit large et facile d'accès et apte à se conformer au pied à tenir et/ou à serrer.In fact, it has always been desired that a shoe should be easy to put on by having a zone for introducing the foot, which is wide and easy to access and capable of conforming to the foot to be held and / or tightened.
La demande de brevet italien VI 91 A 000018 tend à offrir une chaussure offrant ces qualités, grâce à la réalisation de rabats souples qui sont ensuite rapportés sur une base de coque rigide de part et d'autre d'une ouverture antérieure dont elle est pourvue et qui est dimensionnée pour permettre le passage du pied. Une telle construction se révèle complexe à réaliser car elle nécessite de nombreuses pièces qui sont à assembler et à ajuster sur la base de coque et ne simplifie pas la structure de la tige dans la zone correspondant au bas de jambe du skieur.Italian patent application VI 91 A 000018 tends to offer a shoe offering these qualities, thanks to the production of flexible flaps which are then attached to a rigid shell base on either side of a front opening with which it is provided. and which is dimensioned to allow the passage of the foot. Such a construction proves to be complex to carry out because it requires numerous parts which are to be assembled and adjusted on the shell base and does not simplify the structure of the rod in the zone corresponding to the lower leg of the skier.
L'invention vise à remédier à tous ces inconvénients en proposant une chaussure de ski, de type à entrée centrale et/ou par l'avant dite "à volume variable", qui soit de construction extrêmement simplifiée, facile à chausser-déchausser, aisément ajustable sur le bas de jambe et le pied du skieur, et étanche. Également, l'invention a pour objet de proposer une telle chaussure qui soit rigide latéralement pour une bonne transmission des appuis du skieur sur la tige de la chaussure, et relativement flexible dans le sens longitudinal de cette dernière pour maîtriser élastiquement en effort et/ou en amplitude de déplacement les appuis avant et/ou arrière du dit skieur.The invention aims to remedy all these drawbacks by proposing a ski boot, of the central entry type and / or from the front known as "variable volume", which is of extremely simplified construction, easy to put on and take off, easily adjustable on the lower leg and the skier's foot, and waterproof. Also, the object of the invention is to provide such a boot which is rigid laterally for good transmission of the skier's support on the upper of the boot, and relatively flexible in the longitudinal direction of the latter to elastically control in effort and / or in amplitude of displacement, the front and / or rear supports of said skier.
Pour ce faire l'invention concerne la réalisation extrêmement simplifiée d'une chaussure de ski alpin obtenue à partir d'une base de coque munie d'une semelle externe et surmontée d'une tige, pourvue d'une ouverture centrale et/ou antérieure pour le passage du pied d'un skieur, qui forme à sa partie supérieure un collier destiné à enserrer le bas de jambe par l'intermédiaire d'au moins un organe tendeur disposé sur des rabats transversaux, réalisés de part et d'autre de l'ouverture de la tige et destinés à coopérer en fermeture par recouvrement mutuel, sous l'action dudit organe tendeur. La chaussure de ski se caractérise en ce qu'elle se compose de deux parties principales qui sont constituées d'une part de la base de coque longitudinalement ouverte à sa partie supérieure et réalisée en un matériau relativement rigide et d'autre part d'un élément unique de couverture-fermeture rapporté et fixé sur le pourtour de l'ouverture longitudinale supérieure de la dite base de coque, cet élément présentant lui-même et d'un seul tenant une première partie sensiblement verticale formant la tige enserrant le bas de jambe par l'intermédiaire du collier et une seconde partie sensiblement horizontale obtenue en prolongement de la première et formant un capot supérieur de tenue de pied, l'ensemble ainsi formé étant obtenu en un matériau relativement moins rigide que celui de la base de coque.To do this, the invention relates to the extremely simplified embodiment of an alpine ski boot obtained from a shell base provided with an outer sole and surmounted by a rod, provided with a central and / or anterior opening for the passage of a skier's foot, which forms a collar at its upper part intended to enclose the lower leg by means of at least one tensioning member disposed on transverse flaps, produced on either side of the opening of the rod and intended to cooperate in closing by mutual overlap, under the action of said tensioning organ. The ski boot is characterized in that it consists of two main parts which consist on the one hand of the shell base longitudinally open at its upper part and made of a relatively rigid material and on the other hand of a single cover-closure element attached and fixed on the periphery of the upper longitudinal opening of said shell base, this element having itself and in one piece a first substantially vertical part forming the rod enclosing the lower leg by means of the collar and a second substantially horizontal part obtained as an extension of the first and forming an upper foot-holding cover, the assembly thus formed being obtained in a material relatively less rigid than that of the shell base.
La présente invention concerne également les caractéristiques qui ressortiront au cours de la description qui va suivre, et qui devront être considérées isolément ou selon toutes leurs combinaisons techniques possibles.The present invention also relates to the characteristics which will emerge during the description which follows, and which should be considered in isolation or according to all their possible technical combinations.

D'une manière globale la chaussure 1 désignée dans son ensemble sur la figure 1, présente une semelle externe 2 et une base de coque 3 surmontée d'une tige 4 pourvue, sur sa partie supérieure d'une ouverture 5, centrale et/ou antérieure, pour permettre le passage du pied du skieur. La tige 4 forme, dans cette partie supérieure, un collier 6 destiné à enserrer le bas de jambe par l'intermédiaire d'au moins un organe tendeur 7, disposé sur des rabats transversaux 10, soit 10c, 10d, 10e, qui seront décrits plus en détail, plus loin.Overall, the shoe 1 designated as a whole in FIG. 1, has an
Selon le présent exemple de réalisation l'ouverture de la tige 4 s'effectue vers l'avant de la chaussure 1 mais bien entendu l'invention ne s'y limite pas.According to the present embodiment, the opening of the upper 4 takes place towards the front of the shoe 1, but of course the invention is not limited thereto.
Lesdits rabats 10 sont réalisés par conséquent de part et d'autre de l'ouverture frontale de la tige 4 et sont destinés à coopérer en fermeture par recouvrement mutuel, sous l'action des organes tendeur 7.Said
En fait, selon l'invention, la chaussure 1 se compose de deux parties principales qui sont constituées d'une part de la base de coque 3 longitudinalement ouverte 11 à sa partie supérieure et réalisée en un matériau relativement rigide et d'autre part d'un élément unique de couverture-fermeture 12 rapporté et fixé sur le pourtour 11a de l'ouverture longitudinale supérieure 11 de la dite base de coque 3, cet élément 12 présentant lui-même et d'un seul tenant une première partie sensiblement verticale formant la tige 4 enserrant le bas de jambe par l'intermédiaire du collier 6 et une seconde partie sensiblement horizontale 13 obtenue en prolongement de la première et formant un capot supérieur de tenue de pied, l'ensemble ainsi formé étant obtenu en un matériau relativement moins rigide que celui de la base de coque 3.In fact, according to the invention, the shoe 1 consists of two main parts which consist on the one hand of the
Par ailleurs la partie 13 de l'élément de couverture-fermeture 12 formant le capot supérieur de tenue de pied, recouvre l'ouverture longitudinale correspondante 11 de la base de coque 3 en formant au moins deux rabats transversaux adjacents 10, soit 10a, 10b, disposés de part et d'autre de l'axe longitudinal de la base de coque 3 et pourvus d'une pluralité d'organes tendeurs 7 situés en vis-à-vis et agissant sur les dits rabats 10 en direction transversale.Furthermore, the
Préférentiellement l'ouverture longitudinale 11 de la base de coque 3 s'étend quasiment sur toute la longueur de celle-ci à partir d'une zone antérieure proche de sa pointe 14 et selon une largeur telle à déterminer une grande ouverture d'entrée de pied.Preferably the
Ceci a pour avantage de faciliter le chaussage et le déchaussage grâce à un dégagement important au niveau du cou de pied du skieur.This has the advantage of making it easier to put on and take off thanks to a large clearance at the skier's instep.
Plus précisément les rabats transversaux 10 de l'élément de couverture 12, soit 10a et 10b, viennent en recouvrement l'un de l'autre et s'étendent en continu l'un de l'autre, au moins dans la zone du capot supérieur 13 de tenue de pied, en formant entre eux un repli 15 à la manière d'un soufflet afin d'assurer une étanchéité permanente de la chaussure 1, y compris lorsque les dits rabats 10a et 10b sont écartés pour donner passage au pied lors du chaussage ou du déchaussage.More specifically, the
Par contre, mais non obligatoirement les rabats transversaux 10c, 10d, 10e du collier 6 sont obtenus par découpe distincte et viennent réciproquement en recouvrement les uns des autres au niveau de leurs bords libres dirigés vers l'axe longitudinal de l'ouverture 5 au moins dans la zone supérieure de la tige 4.By cons, but not necessarily the transverse flaps 10c, 10d, 10e of the
Comme le montre particulièrement bien la figure 2 les rabats 10c et 10d sont disposés d'un même côté du collier 6 et sont destinés à coopérer avec un rabat 10e unique situé de l'autre côté.As shown particularly well in Figure 2 the flaps 10c and 10d are arranged on the same side of the
Selon une autre caractéristique de l'invention l'élément de couverture-fermeture 12 formant à la fois la tige 4 et le capot supérieur 13 de tenue de pied est rapporté et fixé sur le pourtour 11a de l'ouverture longitudinale supérieure 11 de la base de coque 3, par l'intermédiaire de points de fixation 16 aptes à relier entre elles deux zones périphériques de liaison A et B disposées en superposition, et constituant respectivement le pourtour inférieur de l'élément de couverture-fermeture 12 et le pourtour supérieur de la base de coque 3.According to another characteristic of the invention, the cover-
Il est à noter que ces zones de liaison A et B ont la particularité de présenter des épaisseurs relativement plus faibles que celle de l'élément de couverture-fermeture 12 et de la base de coque 3 proprement dits par ailleurs eux même de rigidités différentes, comme déjà évoqué ci-dessus.It should be noted that these connecting zones A and B have the particularity of having relatively smaller thicknesses than that of the cover-
Les points de fixation 16 de l'élément de couverture-fermeture 12 par rapport à la base de coque 3 sont disposés de préférence sur le pourtour antérieur de la partie horizontale du dit élément formant le capot supérieur 13 de tenue de pied, à partir de deux axes d'articulation 17 situés au niveau des malléoles du pied du skieur afin de permettre leur pivotement relatif l'une par rapport à l'autre , par un effet de flexibilité élastique de la tige 4 par rapport au capot supérieur 13 de tenue de pied, la zone postérieure de celle-ci s'étendant au delà des axes d'articulation 17 et étant dépourvue de points de fixation 16 par rapport à la base de coque 3.The
Selon le présent exemple les points de fixation 16 sont constitués par des rivets, mais il est évident qu'ils pouvaient être remplacés par tout autre moyen d'assemblage connu tel que, par exemple, par un encollage respectif des zones A et B dans une partie également antérieure des pourtours de l'élément 12 et de l'ouverture 11 de la base de coque 3, à partir des mêmes axes d'articulation 17.According to the present example, the
Selon une autre caractéristique de l'invention la base de coque 3 se prolonge à son extrémité postérieure 3a, correspondant à son talon, par une extension verticale 18 relativement rigide s'étendant au dessus de la cheville du skieur vers la base de son mollet, sur une hauteur h correspondant sensiblement aux deux tiers de la hauteur totale H de la chaussure 1, en couvrant au moins partiellement les zones latérales des malléoles du skieur.According to another characteristic of the invention, the
Ainsi on peut dire globalement que la chaussure 1 est constituée de deux tiers de partie rigide (la base de coque 3) et d'un tiers de partie souple (le collier 6).Thus we can say overall that the shoe 1 consists of two thirds of rigid part (the shell base 3) and one third of flexible part (the collar 6).
Il est ainsi obtenue une rigidité latérale optimum car la tige 4, bloquée sur l'extension rigide 18 au niveau de son axe d'articulation 17, chevauche cette dernière jusqu'à son extrémité postérieure au dessus du talon.Optimal lateral rigidity is thus obtained since the rod 4, blocked on the
Avantageusement, l'extrémité verticale postérieure 18 de la base de coque 3 comporte un élément d'appui arrière 19 situé dans l'axe longitudinal de la chaussure 1 et apte à coopérer avec une partie correspondante de la partie formant la tige 4 de l'élément de couverture-fermeture 12 monté pivotant sur la base de coque 3. La tige 4 est ainsi bloquée vers l'arrière et offre au skieur un appui ferme pour son équilibre antéro-postérieur. Pour renforcer la qualité de cet appui, l'extension verticale postérieure 18 de la base de coque 3 comporte de préférence deux bordures 20 d'appui latéral s'étendant en arrière des axes de pivotement 17 et aptes à coopérer avec des parties correspondantes de la tige 4.Advantageously, the rear
Comme représenté sur la figure 3, la chaussure 1 peut également être pourvue de moyens 21 de limitation de l'amplitude du pivotement possible de la tige 4 par rapport à la base de coque 3 et par rapport au capot supérieur 13 de tenue de pied. Ces moyens 21 permettent de contrôler le débattement de la tige 4 et donc la possibilité de flexion postéro-antérieure de la jambe du skieur.As shown in FIG. 3, the shoe 1 can also be provided with
D'autres moyens connus de reprise d'appui arrière et de contrôle de la flexion pourront bien entendu être mis en oeuvre et être équipés d'éléménts de réglage aptes à modifier la position initiale d'appui arrière de la tige 4 par rapport à la base de coque 3 et/ou l'amplitude du débattement autorisé.Other known means for taking up the rear support and controlling the bending could of course be implemented and be equipped with adjustment elements capable of modifying the initial position of the rear support of the rod 4 relative to the
Encore, des dispositifs ou organes déformables élastiquement par exemple pourront être couplés/associés à la tige 4 et à la base de coque 3 afin de varier à la demande l'intensité des efforts résistants à la flexion de la tige.Again, elastically deformable devices or members for example can be coupled / associated with the rod 4 and the
