Definitions
- the present invention relates to a particularly original cross-country ski boot because of the improvements which it benefits.
- Cross-country skiing or Nordic skiing whether used as a means of utility travel or as a leisure and competition activity, allows you to move only at low speed on snow-covered flat or slightly hilly surfaces.
- the boot is simply joined to the ski by the front of the sole and the skier must be able to walk while accelerating more or less the pace, but it is practically impossible for him to evolve by turning tight.
- the cross-country ski boot has a relatively rigid sole on which is mounted a conventional upper whose tightening on the foot is generally ensured by lacing.
- the rigidity of the sole is obtained by various means so that it can pivot at the end of the foot relative to the ski, bend in line with the metatarsus to allow the foot to unwind and in spite of this do not deform in torsion; it is indeed important that the actions of the foot on the sole can be transmitted to the ski by the latter without parasitic torsional deformations in particular disturbing the movement and causing the skier to lose in the effects obtained the precision and the purity of the movement such that it was ordered.
- the present invention aims to remedy this drawback by perfecting the cross-country ski boot so that it blocks the foot in a vertical plane passing the longitudinal axis of the ski, while allowing the folding of this foot at the metatarsus ; thus, the ankle is neutralized for all lateral movements and the foot made integral with the lower leg in the abovementioned vertical plane, while participating, by firm support in torsion, in the anteroposterior metatarsal pivotings.
- the ski boot comprises a shell made of rigid plastic material which can be dismounted on a walking shoe made of relatively thick flexible material for comfort and shoe size compensation; in the flexion zone to the right of the metatarsus, the upper part of the shell is fully perforated until substantially the outsole and the liner which is in closed pore foam, resistant to wear and more or less densified according to the place, has a thickened and compressible part which envelops the top of the foot and which has, opposite the metatarsal openwork of the shell, transverse grooves promoting anteroposterior flexion.
- the outsole of the shell has, opposite the metatarsal perforation, transverse grooves also promoting anteroposterior flexion.
- Such a shoe is particularly effective and efficient.
- the removable liner housed in the rigid shell is not only intended to ensure the comfort and tightness of the wearing of the shell; in reality, this bootie is also designed, on the one hand, as a walking shoe and, on the other hand, as a shoe size compensator.
- the cross-country ski boot of the invention comprises a shell 1 in which a boot 2 is inserted.
- the shell 1 is manufactured by injection of a thermoplastic material having the required rigidity and resistant to bending at low temperature.
- This shell is preferably constituted by elastomers of polyesters such as those sold under the name of Hytrel by du Pont de Nemours or of Arnitel by Akzo and prepared in the quality 55 shore D; it can also be constituted by a thermoplastic polyurethane from Bayer for example, by a polyamide such as that marketed under the name Zytel by du Pont de Nemours, by a polyester-polyamide copolymer, such as that marketed under the name Pebax by Ato-chimie.
- the liner is made from flexible foaming products of the polyurethane family, preferably on a polyether base which better resist hydrolysis; but a polyester base may also be suitable.
- the foam must be closed cell, so that the liner is waterproof and weatherproof: humidity, melt water, snow, ice ...
- This foam must also be resistant to wear so that the liner can be used independently of the hull when driving a vehicle, walking on the ground to the track etc ...; said foam must also be relatively flexible in order to be deformable and compressible, in particular during the above-mentioned flexions of the foot; finally, it must be more or less densifiable by the use of conventional techniques so that certain parts (at the location of the sole for example) are relatively thin and compact while other parts (at the location of the metatarsus and of the instep) are relatively thick and compressible.
- the shell 1 Since the shell 1 is molded in one piece, it monolithically includes a wear sole 3 and a rod 4. This rod has at its front end a toe 5 whose thickness is relatively reduced compared to to that of the outsole 5 which on the other hand is substantially uniform.
- the toe 5 is made integral with a lug 6 intended for the flexing or articulated fixing of the boot on the ski, by means of a thinned tongue 7 extending the sole 3.
- the rod 1 also has at its rear end a part 8 forming a buttress and quarters.
- This rising part 8 is relatively low and has clearance notches 9 facing these ankles. These notches delimit at the instep side ears 10 and 11 which do not meet completely and are separated by a slot 12 across which is disposed a clamp 13 which connects said ears.
- the ears 10 and 11 are also separated from the end 5 by a perforation 14 which extends to the outsole 3.
- the shell 1 is relatively rigid but can however very easily bend at the 'location of the perforation 14 that is to say at the level of the metatarsus.
- transverse grooves 15 can be formed recessed in the underside of the outsole 3 opposite the aforementioned cutout 14.
- the liner 2 also came from molding but foaming with variable densification.
- the liner is therefore monolithic and has a outsole 16 secured to a rod 17.
- the outsole 16 has a substantially constant and relatively small thickness.
- the rear part 18 of the rod which corresponds to the buttress and to the quarters of the shell as regards their upper cutouts, has a thickness which is also substantially constant but slightly greater.
- the sole 16 and the rear part 18 of the upper are therefore relatively thin and compact.
- the end 19 of the upper 17 of the liner is relatively thick and compressible. It is the same also for the part 20 of the rod which envelops the top of the foot and consequently fills the slot 12 and the perforation 14 of the shell.
- This part 20 is thicker to the right of the perforation 14, that is to say of the metatarsus, than to the right of the ears 10, 11 and the tip 5, that is to say respectively of the instep and toes, zones in which the thickness of the part 20 is progressively decreasing as it moves away from the cutting 14.
- part 20 of the liner protects the foot against external agents and against any bruising due to the hardness of the shell; in particular, by blocking the strap 33, the ears 10 and 11 of the shell are tightened on the liner and the upper 19 of this liner is compressed on the instep; this ensures perfect attachment of the shoe with the foot.
- transverse grooves 21 are formed in the hollow in said part 20 in line with the cut-out 14; so the metatarsal flexion of the foot at through the liner is it greatly facilitated by the compressibility of the veil 22 which remains in the part 20 and the bringing together of the ribs 23 separating the grooves 21.
- the whistle 24 is glued to the top of the outsole 3 of the shell 1. But it is obvious that the same whistle may have come from molding with the outsole 16 of the boot 2, a reinforcement of this whistle may possibly be provided.
- the shell 1 and the liner 2 must remain integral with each other when they put on a foot and are tightened on it by the strap 13 and this not only during a walk in the absence of skis, but also when skiing.
- the rear part 18 of the liner 2 is convex and cooperates by interlocking for its retention with the rear part 8 also convex and of complementary shape to the shell 1.
- the neck 25 of the boot 2 which slightly overcomes the notches 9 is provided with a flexible lining 26 protecting the lower legs; this lining 26 is sewn on the neck and can possibly be extended by a kind of chimney fitting onto the socks.

Abstract
Description
La présente invention concerne une chaussure de ski de fond particulièrement originale en raison des perfectionnements dont elle bénéficie.The present invention relates to a particularly original cross-country ski boot because of the improvements which it benefits.
Le ski de fond ou ski nordique, qu'il soit utilisé comme moyen de déplacement utilitaire ou comme activité de loisir et de compétition permet de ne se déplacer qu'à faible vitesse sur des surfaces enneigées plates ou faiblement vallonnées.Cross-country skiing or Nordic skiing, whether used as a means of utility travel or as a leisure and competition activity, allows you to move only at low speed on snow-covered flat or slightly hilly surfaces.
Dans cette spécialité particulière, la chaussure est simplement solidarisée au ski par l'avant de la semelle et le skieur doit pouvoir marcher en accélérant plus ou moins l'allure, mais il lui est pratiquement impossible d'évoluer en virant serré.In this particular specialty, the boot is simply joined to the ski by the front of the sole and the skier must be able to walk while accelerating more or less the pace, but it is practically impossible for him to evolve by turning tight.
Dans les techniques les plus récentes, la chaussure de ski de fond comporte une semelle relativement rigide sur laquelle est montée une tige classique dont le serrage sur le pied est généralement assuré par laçage. La rigidité de la semelle est obtenue par divers moyens de façon qu'elle puisse pivoter en bout de pied par rapport au ski, fléchir au droit du métatarse pour permettre le déroulement du pied et malgré cela ne pas se déformer en torsion ; il est en effet important que les actions du pied sur la semelle puissent être transmises au ski par celle-ci sans que des déformations parasites en torsion notamment perturbent le mouvement et fassent perdre au skieur dans les effets obtenus la précision et la pureté du mouvement tel qu'il a été commandé.In the most recent techniques, the cross-country ski boot has a relatively rigid sole on which is mounted a conventional upper whose tightening on the foot is generally ensured by lacing. The rigidity of the sole is obtained by various means so that it can pivot at the end of the foot relative to the ski, bend in line with the metatarsus to allow the foot to unwind and in spite of this do not deform in torsion; it is indeed important that the actions of the foot on the sole can be transmitted to the ski by the latter without parasitic torsional deformations in particular disturbing the movement and causing the skier to lose in the effects obtained the precision and the purity of the movement such that it was ordered.
Tous les perfectionnements qui ont été apportés jusqu'à présent, tant en ce qui concerne l'articulation de l'extrémité avant de la semelle sur le ski, que la rigidité de cette semelle pour qu'elle soit à la fois réfléchissante au droit du métatarse et résistante à la torsion, ne donnent pas entière satisfaction au skieur. Pour qu'il en soit ainsi, il faudrait que le pied n'ait pas d'autres mouvements relatifs par rapport à la semelle que ceux qui sont nécessaires à la pratique de la marche glissée. Or, la tige qui est montée sur cette semelle tolère, notamment à sa jonction avec ladite semelle, des mouvements du pied relativement à celle-ci.All the improvements that have been made so far, both as regards the articulation of the front end of the sole on the ski, and the rigidity of this sole so that it is both reflective at the right of the metatarsal and resistant to torsion, do not give complete satisfaction to the skier. For this to be so, the foot would have to have no other relative movements with respect to the sole than those which are necessary for the practice of sliding walking. However, the upper which is mounted on this sole tolerates, in particular at its junction with said sole, movements of the foot relative to the latter.
La présente invention a pour but de remédier à cet inconvénient en perfectionnant la chaussure de ski de fond pour qu'elle bloque le pied dans un plan vertical passant l'axe longitudinal du ski, tout en permettant la pliure de ce pied au niveau du métatarse ; ainsi, la cheville se trouve-t-elle neutralisée pour tous les mouvements latéraux et le pied rendu solidaire du bas de jambe dans le plan vertical précité, tout en participant, par un maintien ferme en torsion, aux pivotements antéro-postérieurs métatarsiens.The present invention aims to remedy this drawback by perfecting the cross-country ski boot so that it blocks the foot in a vertical plane passing the longitudinal axis of the ski, while allowing the folding of this foot at the metatarsus ; thus, the ankle is neutralized for all lateral movements and the foot made integral with the lower leg in the abovementioned vertical plane, while participating, by firm support in torsion, in the anteroposterior metatarsal pivotings.
Cette chaussure de l'invention satisfait alors aux impératifs suivants :
- - pivoter en bout par rapport au ski,
- - fléchir dans sa structure au droit du métatarse,
- - améliorer la rigidification de la semelle,
- - reporter cette rigidification sur le pied,
- - assurer cependant un excellent confort de ce pied,
- - protéger contre les éléments extérieurs et contre l'abrasion.
- - pivot at the end relative to the ski,
- - flex in its structure in line with the metatarsus,
- - improve the stiffening of the sole,
- - transfer this stiffening to the foot,
- - however ensuring excellent comfort for this foot,
- - protect against external elements and against abrasion.
Pour atteindre ce but et conformément à l'invention, la chaussure de ski comporte une coque en matière plastique rigide s'emboîtant de façon démontable sur un chausson de marche en matière souple relativement épais pour le confort et la compensation de pointure ; dans la zone de flexion au droit du métatarse, la partie tige de la coque est entièrement ajourée jusqu'à sensiblement la semelle d'usure et le chausson qui est en mousse à pores fermés, résistante à l'usure et plus ou moins densifiée suivant l'endroit, comporte une partie épaissie et compressible qui enveloppe le dessus du pied et qui présente, en regard de l'ajourage métatarsien de la coque, des rainures transversales favorisant la flexion antéro-postérieure.To achieve this object and in accordance with the invention, the ski boot comprises a shell made of rigid plastic material which can be dismounted on a walking shoe made of relatively thick flexible material for comfort and shoe size compensation; in the flexion zone to the right of the metatarsus, the upper part of the shell is fully perforated until substantially the outsole and the liner which is in closed pore foam, resistant to wear and more or less densified according to the place, has a thickened and compressible part which envelops the top of the foot and which has, opposite the metatarsal openwork of the shell, transverse grooves promoting anteroposterior flexion.
Subsidiairement, la semelle d'usure de la coque présente, en regard de l'ajourage métatarsien, des rainures transversales favorisant également la flexion antéro-postérieure.Alternatively, the outsole of the shell has, opposite the metatarsal perforation, transverse grooves also promoting anteroposterior flexion.
Une telle chaussure est particulièrement efficace et performante.Such a shoe is particularly effective and efficient.
Un autre avantage extrêmement important mérite d'être signalé. Le chausson démontable logé dans la coque rigide n'est pas seulement destiné à assurer le confort et l'étanchéité du port de la coque ; en réalité, ce chausson est également conçu, d'une part, comme une chaussure permettant la marche et, d'autre part, comme un élément compensateur de pointure.Another extremely important benefit is worth noting. The removable liner housed in the rigid shell is not only intended to ensure the comfort and tightness of the wearing of the shell; in reality, this bootie is also designed, on the one hand, as a walking shoe and, on the other hand, as a shoe size compensator.
Ce dernier aspect de la conception permet de réduire l'outillage de moulage au plus strict minimum. En effet, pour 12 pointures de chaussures de ski de fond, il suffit de réaliser, pour la coque 4 moules au maximum, et pour le chausson 4 moules et 12 formes au maximum.This last aspect of the design makes it possible to reduce the molding tools to the strictest minimum. Indeed, for 12 sizes of cross-country ski boots, it suffices to make, for the
Pour plus de précision et en ce qui concerne la taille 40 par exemple :
- - un moule permet d'obtenir une coque commune convenant pour les pointures 38, 39 et 40,
- - un autre moule permet d'obtenir la conformation extérieure de chausson adaptée à cette coque et coopère sélectivement avec trois formes 38, 39 et 40 permettant d'obtenir la conformation intérieure des trois chaussons ayant ces pointures.
- - a mold makes it possible to obtain a common shell suitable for sizes 38, 39 and 40,
- - Another mold makes it possible to obtain the external conformation of the liner adapted to this shell and cooperates selectively with three shapes 38, 39 and 40 making it possible to obtain the internal conformation of the three slippers having these sizes.
Il est clair que l'outillage de moulage se trouve considérablement réduit et il en est de même par conséquent pour le coût de la fabrication. Mais à cela s'ajoute un autre avantage à caractère commercial. En effet, il devient possible de vendre indépendamment la coque et le chausson, de réduire le stock au niveau des coques et de faciliter les commandes, de rendre la location plus facile puisqu'une même coque peut recevoir 3 ou 4 tailles de chausson.It is clear that the molding tool is considerably reduced and it is the same consequently for the cost of manufacture. But there is another commercial advantage. Indeed, it becomes possible to sell the shell and the liner independently, to reduce the stock in the hulls and to facilitate the orders, to make the rental easier since the same shell can receive 3 or 4 sizes of liner.
Divers autres caractéristiques et avantages de l'invention ressortent d'ailleurs de la description détaillée qui suit.Various other characteristics and advantages of the invention will also emerge from the detailed description which follows.
Une forme de réalisation de l'objet de l'invention est représentée, à titre d'exemple non limitatif, sur le dessin annexé.An embodiment of the object of the invention is shown, by way of nonlimiting example, in the accompanying drawing.
Sur ce dessin :
- la figure 1 est une perspective montrant par le dessus une chaussure de ski de fond conformément à l'invention,
- la figure 2 est une perspective illustrant par le dessous la même chaussure,
- la figure 3 est une perspective faisant ressortir le chausson de ladite chaussure avant qu'il soit monté dans la coque,
- la figure 4 est une coupe longitudinale de ladite chaussure,
- les figures 5 à 7 sont des coupes transversales prises suivant les lignes V-V à VII-VII respectivement de la figure 4.
- FIG. 1 is a perspective showing from above a cross-country ski boot according to the invention,
- FIG. 2 is a perspective illustrating the same shoe from below,
- FIG. 3 is a perspective showing the liner of said shoe before it is mounted in the shell,
- FIG. 4 is a longitudinal section of said shoe,
- FIGS. 5 to 7 are cross sections taken along lines VV to VII-VII respectively of FIG. 4.
Ainsi que cela ressort clairement du dessin, la chaussure de ski de fond de l'invention comporte une coque 1 dans laquelle est inserré un chausson 2.As is clear from the drawing, the cross-country ski boot of the invention comprises a shell 1 in which a
La coque 1 est fabriquée par injection d'une matière thermoplastique ayant la rigidité requise et résistant aux flexions à basse température. Cette coque est de préférence constituée par des élastomères de polyesters tels que ceux commercialisés sous le nom de Hytrel par du Pont de Nemours ou de Arnitel par Akzo et préparés dans la qualité 55 shore D ; elle peut aussi être constituée par un polyuréthane thermoplastique de chez Bayer par exemple, par un polyamide tel que celui commercialisé sous le nom de Zytel par du Pont de Nemours, par un copolymère de polyester-polyamide, tel que celui commercialisé sous le nom de Pebax par Ato-chimie.The shell 1 is manufactured by injection of a thermoplastic material having the required rigidity and resistant to bending at low temperature. This shell is preferably constituted by elastomers of polyesters such as those sold under the name of Hytrel by du Pont de Nemours or of Arnitel by Akzo and prepared in the quality 55 shore D; it can also be constituted by a thermoplastic polyurethane from Bayer for example, by a polyamide such as that marketed under the name Zytel by du Pont de Nemours, by a polyester-polyamide copolymer, such as that marketed under the name Pebax by Ato-chimie.
Le chausson est fabriqué à partir de produits moussants souples de la famille des polyurétha- nes de préférence sur une base polyéther qui résistent mieux à l'hydrolyse ; mais une base polyester peut également convenir. La mousse doit être à cellules fermées, pour que le chausson soit étanche et résiste aux intempéries : humidité, eau de fusion, neige, glace... Cette mousse doit aussi être résistante à l'usure pour que le chausson puisse être utilisé indépendamment de la coque lors de la conduite d'un véhicule, de la marche sur le terrain jusqu'à la piste etc... ; ladite mousse doit aussi être relativement souple afin d'être déformable et compressible notamment lors des flexions précitées du pied ; elle doit enfin être plus ou moins densifiable par la mise en oeuvre des techniques classiques afin que certaines parties (à l'endroit de la semelle par exemple) soient relativement minces et compactes alors que d'autres parties (à l'endroit du métatarse et du cou de pied) soient relativement épaisses et compressibles.The liner is made from flexible foaming products of the polyurethane family, preferably on a polyether base which better resist hydrolysis; but a polyester base may also be suitable. The foam must be closed cell, so that the liner is waterproof and weatherproof: humidity, melt water, snow, ice ... This foam must also be resistant to wear so that the liner can be used independently of the hull when driving a vehicle, walking on the ground to the track etc ...; said foam must also be relatively flexible in order to be deformable and compressible, in particular during the above-mentioned flexions of the foot; finally, it must be more or less densifiable by the use of conventional techniques so that certain parts (at the location of the sole for example) are relatively thin and compact while other parts (at the location of the metatarsus and of the instep) are relatively thick and compressible.
Etant donné que la coque 1 est venue de moulage en une seule pièce, elle comporte de façon monolithique une semelle d'usure 3 et une tige 4. Cette tige présente à son extrémité antérieure un bout 5 dont l'épaisseur est relativement réduite par rapport à celle de la semelle d'usure 5 qui par contre est sensiblement uniforme. Le bout 5 est rendu solidaire d'une patte 6 destinée à la fixation fléchissante ou articulée de la chaussure sur le ski, par l'intermédiaire d'une languette amincie 7 prolongeant la semelle 3.Since the shell 1 is molded in one piece, it monolithically includes a wear sole 3 and a
La tige 1 présente également à son extrémité postérieure une partie 8 formant contrefort et quartiers. Cette partie montante 8 est relativement basse et présente en regard de la cheville des échancrures de dégagement 9. Ces échancrures délimitent à l'endroit du cou de pied des oreilles latérales 10 et 11 qui ne se rejoignent pas complètement et se trouvent séparées par une fente 12 en travers de laquelle est disposée une bride de serrage 13 qui relie lesdites oreilles.The rod 1 also has at its rear end a
Suivant l'invention, les oreilles 10 et 11 sont également séparées du bout 5 par un ajourage 14 qui s'étend jusqu'à la semelle d'usure 3. Ainsi, la coque 1 est relativement rigide mais peut cependant très facilement fléchir à l'endroit de l'ajourage 14 c'est-à-dire au niveau du métatarse. D'ailleurs, pour faciliter encore la flexion antéro-postérieure de la coque, des rainures transversales 15 peuvent être ménagées en creux dans le dessous de la semelle d'usure 3 en regard de l'ajourage 14 précité.According to the invention, the
Le chausson 2 est lui aussi venu de moulage mais en moussant avec une densification variable. Le chausson est donc monolithique et présente une semelle d'usure 16 solidaire d'une tige 17.The
La semelle d'usure 16 a une épaisseur sensiblement constante et relativement faible. La partie postérieure 18 de la tige qui correspond au contrefort et aux quartiers de la coque quant à leurs découpes supérieures, a une épaisseur également sensiblement constante mais un peu plus forte. La semelle 16 et la partie postérieure 18 de la tige sont donc relativement minces et compactes. Par contre, le bout 19 de la tige 17 du chausson est relativement épaisse et compressible. Il en est de même également pour la partie 20 de la tige qui enveloppe le dessus du pied et comble par conséquent la fente 12 et l'ajourage 14 de la coque. Cette partie 20 est plus épaisse au droit de l'ajourage 14, c'est-à-dire du métatarse, qu'au droit des oreilles 10, 11 et du bout 5, c'est-à-dire respectivement du cou de pied et des doigts de pieds, zones dans lesquelles l'épaisseur de la partie 20 est progressivement décroissante en s'éloignant de l'ajcurage 14.The
Suivant l'invention, la partie 20 du chausson protège le pied contre les agents extérieurs et contre toute meurtrissure due à la dureté de la coque ; en particulier, en bloquant la bride 33, on serre les oreilles 10 et 11 de la coque sur le chausson et on comprime le dessus 19 de ce chausson sur le cou de pied ; on assure ainsi une solidarisation parfaite de la chaussure avec le pied. Mais étant donné l'épaisseur relativement grande de la partie 20 de la tige 17 du chausson 2, des rainures transversales 21 sont ménagées en creux dans ladite partie 20 au droit de l'ajourage 14 ; ainsi, la flexion métatarsienne du pied à travers le chausson se trouve-t-elle grandement facilitée grâce à la compressibilité du voile 22 qui subsiste dans la partie 20 et au rapprochement des nervures 23 séparant les rainures 21.According to the invention,
Bien entendu, dans cette chaussure, il est souhaitable d'incorporer un sifflet 24 formant cambrion et talon. Dans la forme de réalisation représentée sur le dessin, le sifflet 24 est collé sur le dessus de la semelle d'usure 3 de la coque 1. Mais il est bien évident que le même sifflet peut être venu de moulage avec la semelle d'usure 16 du chausson 2, un renforcement de ce sifflet pouvant éventuellement être prévu.Of course, in this shoe, it is desirable to incorporate a
Il est bien évident que la coque 1 et le chausson 2 doivent rester solidaires entre eux lorsqu'ils chaussent un pied et sont serrés sur celui-ci par la bride 13 et cela non seulement lors d'une marche en l'absence de skis, mais également lors de la pratique du ski. A cet effet, la partie postérieure 18 du chausson 2 est convexe et coopère par emboîtement pour sa retenue avec la partie postérieure 8 également convexe et de forme complémentaire de la coque 1.It is obvious that the shell 1 and the
Enfin, comme le montrent les figures 1, 2 et 4 et plus précisément la figure 7, l'encolure 25 du chausson 2 qui surmonte légèrement les échancrures 9 est munie d'une garniture souple 26 protégeant le bas des jambes ; cette garniture 26 est cousue sur l'encolure et peut éventuellement être prolongée par une sorte de cheminée s'emboîtant sur les chaussettes.Finally, as shown in Figures 1, 2 and 4 and more specifically Figure 7, the
