Description

La présente invention concerne une construction de chaussure au moins partiellement étanche et destinée notamment à un usage de type hiver.The present invention relates to a shoe construction at least partially waterproof and intended in particular for winter use.

Le but de la présente invention est de proposer une construction de chaussure qui soit d'une construction simple et d'un prix de revient avantageux tout en présentant les caractéristiques souhaitées, notamment en terme de confort, chaleur, étanchéité.The object of the present invention is to provide a shoe construction which is of a simple construction and an advantageous cost price while presenting the characteristics desired, especially in terms of comfort, warmth, waterproofing.

Ce but est atteint dans la présente invention par le fait que la chaussure comporte une semelle, une tige externe comportant une partie étanche et un élément de renfort externe assemblé à la tige par collage au moins dans la partie étanche de celle-ciThis object is achieved in the present invention by the fact that the shoe comprises a sole, an external upper comprising a waterproof part and an external reinforcement element assembled to the rod by gluing at least in the sealed part thereof

En effet, le fait que le renfort externe soit collé et non pas cousu comme dans les constructions de chaussure usuelles permet généralement de préserver l'étanchéité de la chaussure et d'éviter d'avoir recours à des moyens coûteux pour étancher les coutures qui auraient été réalisées.Indeed, the fact that the external reinforcement is glued and not sewn as in the usual shoe constructions generally makes it possible to preserve the tightness of the shoe and avoid resorting to expensive means to seal the seams that would have been carried out.

De toute façon, l'invention sera mieux comprise à l'aide de la description qui suit en référence aux dessins schématiques annexés en illustrant à titre d'exemple non limitatif un mode de réalisation préféré, et dans lequel :

  • la figure 1 est une vue en perspective éclatée de la tige externe de la chaussure avant assemblage,
  • la figure 2 est une vue du chausson,
  • la figure 3 est une vue en coupe transversale de la chaussure assemblée, sans le chausson,
  • la figure 4 est une vue similaire à la figure 1 de la tige externe d'une chaussure selon un second mode de réalisation,
  • la figure 5 est une vue similaire à la figure 1 d'une chaussure selon un troisième mode de réalisation.
In any case, the invention will be better understood with the aid of the description which follows with reference to the appended schematic drawings, illustrating by way of nonlimiting example a preferred embodiment, and in which:
  • FIG. 1 is an exploded perspective view of the external upper of the shoe before assembly,
  • FIG. 2 is a view of the boot,
  • FIG. 3 is a cross-sectional view of the assembled shoe, without the boot,
  • FIG. 4 is a view similar to FIG. 1 of the outer upper of a shoe according to a second embodiment,
  • Figure 5 is a view similar to Figure 1 of a shoe according to a third embodiment.

Ainsi que le montre la figure 1, la chaussure se compose :

  • d'une semelle externe 30,
  • d'une tige souple fermée en forme de botte, c'est-à-dire une tige haute 10 comportant une seule ouverture 11 à son extrémité supérieure. Cette tige 10 est en un matériau souple et étanche, et notamment en cuir ou textile enduit, et est fermée à son extrémité inférieure par une semelle 12, notamment en PVC,
  • d'un renfort 20 comportant une partie arrière ou renfort talon 21 entourant le talon et deux volets latéraux 22 reliés audit renfort arrière 21, et recouvrant la tige 10 de la chaussure depuis la semelle externe 30 jusqu'au niveau du cou de pied 15 de la tige,
  • chaque volet latéral 22 comporte à son extrémité supérieure des passants 23 destinés à recevoir un lacet 25 pour le serrage de la tige externe 10 de la chaussure dans la zone du cou de pied.
As shown in Figure 1, the shoe consists of:
  • an outer sole 30,
  • a flexible rod closed in the form of a boot, that is to say a high rod 10 having a single opening 11 at its upper end. This rod 10 is made of a flexible and waterproof material, and in particular of coated leather or textile, and is closed at its lower end by a sole 12, in particular made of PVC,
  • of a reinforcement 20 comprising a rear part or heel reinforcement 21 surrounding the heel and two lateral flaps 22 connected to said rear reinforcement 21, and covering the upper 10 of the shoe from the outer sole 30 to the level of the instep 15 of the stem,
  • each lateral flap 22 has at its upper end loops 23 intended to receive a lace 25 for tightening the external upper 10 of the shoe in the area of the instep.

De préférence, le renfort 20 est en un matériau polymère tel que du polyuréthane souple, et présente des zones de raideur différentes en fonction de l'effet recherché. Ainsi, le renfort 20 sera plus épais dans sa partie arrière 21 pour assurer un bon emboítement et une bonne tenue/protection du talon. L'ensemble renfort talon 21 et volets de serrage 22 sera aussi de préférence moulé en forme pour obtenir une adaptation au pied et un serrage optimum.Preferably, the reinforcement 20 is made of a polymer material such as flexible polyurethane, and has different stiffness zones depending on the desired effect. So the reinforcement 20 will be thicker in its rear part 21 to ensure good interlocking and good heel hold / protection. The heel reinforcement 21 and clamping flap 22 assembly will also be preferably molded in shape to obtain an adaptation to the foot and an optimum tightening.

Selon un mode de construction préféré, l'ensemble renfort 20/21/22 est assemblé sur la tige externe 10 par collage, dans une zone de collage s'étendant depuis la semelle externe 30 au moins jusqu'à une limite supérieure de collage Δ s'étendant sensiblement à mi-hauteur de la tige. La colle sera de préférence une colle à base de polyuréthane.According to a preferred construction method, the reinforcement assembly 20/21/22 is assembled on the rod outer 10 by bonding, in a bonding zone extending from the outer sole 30 to less up to an upper bonding limit Δ extending substantially halfway up the rod. The glue will preferably be a polyurethane-based glue.

Cette construction permet :

  • de garantir l'étanchéité de la chaussure, puisqu'elle nécessite un minimum de coutures, toujours préjudiciables à une bonne étanchéité,
  • de simplifier au maximum la construction et donc de réduire d'autant les coûts, puisque toute la tige externe est souple et que les seuls moyens de raidissements/serrage sont reportés sur un seul élément, à savoir l'ensemble renfort/volet de serrage, et que la fixation de l'ensemble renfort 20/21/22 par collage au lieu des coutures traditionnelles évite le recours à des techniques d'étanchage toujours coûteuses,
  • d'obtenir néanmoins un serrage performant, ce qui n'est généralement pas le cas dans une construction de type botte, puisque les extrémités supérieures des volets de serrage sont libres par rapport à la tige,
  • de dissocier les aspects, étanchéité par la tige externe et confort/chaleur par le chausson interne.
This construction allows:
  • to guarantee the waterproofness of the shoe, since it requires a minimum of seams, always detrimental to a good waterproofing,
  • to simplify construction as much as possible and therefore to reduce costs accordingly, since the entire external rod is flexible and the only stiffening / tightening means are carried over to a single element, namely the reinforcement / tightening flap assembly, and that the fixing of the reinforcement assembly 20/21/22 by gluing instead of the traditional seams avoids the use of always costly sealing techniques,
  • nevertheless obtain an efficient clamping, which is generally not the case in a boot type construction, since the upper ends of the clamping flaps are free relative to the rod,
  • to dissociate the aspects, tightness by the external rod and comfort / warmth by the internal liner.

La tige souple 11 peut être le cas échéant munie elle-même d'un contrefort talon 13 assemblé à ladite tige par une couture 14, dans ce cas la couture 14 est recouverte et étanchée par l'ensemble renfort 21 / ailes de serrage 22, et est donc complètement protégée vis à vis de l'extérieur puisque le collage de l'ensemble renfort 20/21/22 s'étend jusqu'à la ligne de collage Δ et donc au-dessus de la couture 14. Dans ce cas, la raideur du renfort talon 21 externe sera adaptée à celle du contrefort talon 13 interne.The flexible rod 11 can be optionally provided with a heel counter 13 assembled to said rod by a seam 14, in this case the seam 14 is covered and sealed by the reinforcement 21 / clamping wings 22 assembly, and is therefore completely protected from the outside since the bonding of the reinforcement assembly 20/21/22 extends to the bonding line Δ and therefore above the seam 14. In this case, the stiffness of the external heel reinforcement 21 will be adapted to that of the internal heel counter 13.

Selon la hauteur de la chaussure, des moyens de serrage complémentaires peuvent être prévus au niveau de la cheville/bas de jambe. En l'occurrence, ces moyens de serrage sont constitués par une sangle 50 munie de moyens auto-agrippant de type velcro apte à rapprocher les deux ailes 26 d'une extension verticale du renfort 21 en formant un collier autour du bas de jambe. Dans tous les cas, les seuls moyens de serrage 25, 50 de la chaussure autour du pied sont situés sur la partie renfort 20 de la tige externe 10. Un moyen de fermeture, en l'occurrence un lacet 16, peut également être prévu pour fermer l'ouverture 11 de la tige 10 et éviter toute pénétration d'eau, neige,...etc., à l'intérieur de celle-ci. Le chausson interne 40 peut avoir n'importe quelle construction.Depending on the height of the shoe, additional tightening means can be provided at the ankle / lower leg. In this case, these clamping means are constituted by a strap 50 provided with Velcro type hook-and-loop means capable of bringing together the two wings 26 of a vertical extension of the reinforcement 21 by forming a collar around the bottom of leg. In all cases, the only means of tightening 25, 50 of the shoe around the foot are located on the reinforcement part 20 of the external rod 10. A closure means, in the occurrence a lace 16, can also be provided to close the opening 11 of the rod 10 and avoid any penetration of water, snow, ... etc., inside it. Internal liner 40 can have any construction.

De préférence, le chausson interne 40 est amovible, de façon à en faciliter par exemple le nettoyage et le séchage.Preferably, the internal liner 40 is removable, so as to facilitate, for example, the cleaning and drying.

Avantageusement, le chausson est muni à son extrémité inférieure d'une épaisse semelle 41, de préférence collée, correspondant à une semelle intermédiaire, dite cuvette, d'une semelle externe classique. Advantageously, the bootie is provided at its lower end with a thick sole. 41, preferably glued, corresponding to an intermediate sole, called a bowl, of a classic outsole.

Cette semelle 41 est en un matériau amortissant tel que mousse PU, EVA.This sole 41 is made of a damping material such as PU foam, EVA.

Le fait de prévoir cette semelle 41 sur le chausson, et donc à l'intérieur de la chaussure, présente de nombreux avantages :

  • d'une part, ladite semelle 41 est maintenue au chaud, à l'intérieur de la chaussure, et ne durcit pas au froid, ce qui aurait pour effet de supprimer les caractéristiques d'amortissement de celle-ci, et la chaussure reste donc confortable quelles que soient les conditions extérieures,
  • la semelle 41 intègre une différence de hauteur dite Δh entre le talon et la zone avant du pied, et permet donc une marche plus facile avec le chausson seul,
  • le sous-ensemble semelle/chausson est enfilé à l'intérieur de la tige externe et est donc complètement amovible,
  • le produit global présente d'excellentes caractéristiques de confort, amortissement, chaleur, étanchéité, tout en étant d'un prix de revient particulièrement avantageux.
Providing this sole 41 on the liner, and therefore inside the shoe, has many advantages:
  • on the one hand, said sole 41 is kept warm, inside the shoe, and does not harden in the cold, which would have the effect of eliminating the damping characteristics thereof, and the shoe therefore remains comfortable whatever the external conditions,
  • the sole 41 incorporates a height difference called Δh between the heel and the front area of the foot, and therefore allows easier walking with the sole alone,
  • the sole / liner sub-assembly is threaded inside the external upper and is therefore completely removable,
  • the overall product has excellent characteristics of comfort, cushioning, heat, tightness, while being of a particularly advantageous cost price.

Le mode de réalisation de la figure 4 se distingue essentiellement du mode de réalisation précédent par le fait que les moyens de serrage sont essentiellement disposés à l'intérieur de la chaussure.The embodiment of FIG. 4 essentially differs from the embodiment precedent by the fact that the clamping means are essentially arranged inside the shoe.

Cette chaussure se compose :

  • d'une semelle externe 130,
  • d'une tige mi-haute 110, en matériau étanche tel que du textile enduit, munie à son extrémité supérieure d'une large ouverture 111 et à son extrémité inférieure d'une semelle 112 et comportant dans la zone talon un contrefort talon 113 assemblé à la tige par des coutures 114,
  • d'une guêtre souple étanche 140 cousue en 141 le long de l'ouverture 111 de la tige et remontant le long de la jambe de l'utilisateur, la guêtre 140 étant munie d'une ouverture longitudinale latérale fermée par une fermeture à glissière 142 et d'un cordon de serrage 143 de son ouverture supérieure 144,
  • d'un renfort 120 comportant une partie arrière ou renfort talon comportant deux branches 121 recouvrant latéralement la zone talon de la tige mi-haute 110, et s'étendant vers le haut en se rejoignant pour former un collier 126 entourant la partie haute de la tige 141 et la guêtre 140, le collier 126 étant muni de moyens de serrage 150 de type velcro ou autre.
This shoe consists of:
  • an outer sole 130,
  • a mid-high rod 110, made of waterproof material such as coated textile, provided at its upper end with a wide opening 111 and at its lower end with a sole 112 and comprising in the heel area an heel stiffener 113 assembled to the rod by seams 114,
  • a flexible waterproof gaiter 140 sewn at 141 along the opening 111 of the rod and rising along the user's leg, the gaiter 140 being provided with a lateral longitudinal opening closed by a zipper 142 and a drawstring 143 from its upper opening 144,
  • of a reinforcement 120 comprising a rear part or heel reinforcement comprising two branches 121 laterally covering the heel zone of the mid-high upper 110, and extending upwards by joining to form a collar 126 surrounding the upper part of the rod 141 and the gaiter 140, the collar 126 being provided with clamping means 150 of the Velcro or other type.

Un chausson amovible (non représenté sur le dessin), similaire au chausson 40 de la figure 2 est destiné à être introduit à l'intérieur de la tige pour fournir le confort et les caractéristiques d'isolation thermique et d'amortissement souhaitées.A removable liner (not shown in the drawing), similar to liner 40 in the figure 2 is intended to be inserted inside the upper to provide comfort and features thermal insulation and damping desired.

La tige mi-haute 110 est par ailleurs munie d'un système de serrage interne constitué de deux volets souples 115 respectivement médial et latéral, s'étendant dans la zone cou de pied de la chaussure. Ces deux volets 115 sont fixés à leur extrémité inférieure 116 à la tige 110 et à la semelle 130, notamment dans la zone d'assemblage 112 mutuel de celles-ci appelée prise de montage.The mid-high rod 110 is also provided with an internal clamping system consisting of two flexible flaps 115 respectively medial and lateral, extending in the instep area of the shoe. These two flaps 115 are fixed at their lower end 116 to the rod 110 and to the sole 130, in particular in the mutual assembly area 112 of these called grip mounting.

Ces deux volets 115 sont par ailleurs fixés dans leur zone arrière par une couture 117 à la tige 110. Le rôle des coutures 117 est d'une part de renforcer la liaison des volets à la tige, et d'autre part de faciliter la mise en place du chausson, les volets 115 fixés dans leur zone arrière ne gênant pas son introduction.These two flaps 115 are moreover fixed in their rear region by a seam 117 at the rod 110. The role of the seams 117 is on the one hand to strengthen the connection of the flaps to the rod, and on the other hand to facilitate the installation of the liner, the flaps 115 fixed in their zone rear not obstructing its introduction.

Les volets de serrage 115 sont munis à leur extrémité supérieure libre de passants 118 recevant un lacet 119 pour le serrage du pied de l'utilisateur à l'intérieur de la tige 110. Le lacet 119 peut être fermé par un noeud ou un système de bloqueur 160 tel que connu par le brevet français n° 2 706 743.The clamping flaps 115 are provided at their upper end free of passers-by 118 receiving a lace 119 for tightening the user's foot inside the upper 110. The lace 119 can be closed by a knot or a blocker system 160 as known by the French Patent No. 2,706,743.

De même que dans l'exemple précédent, le renfort de tige 120 est fixé à la tige 110 de la chaussure jusqu'à mi-hauteur de celle-ci, c'est-à-dire depuis la semelle externe 130 jusqu'à la limite supérieure de collage Δ.As in the previous example, the rod reinforcement 120 is fixed to the rod 110 of the shoe to mid-height thereof, that is to say from the outer sole 130 to the upper bonding limit Δ.

De même que précédemment, la forme du renfort de tige 120 est prévue de façon à couvrir et à étancher par son collage toutes les coutures 117, 114 de la tige 110 située dans une partie étanche de celle-ci.As before, the shape of the rod reinforcement 120 is provided so as to cover and to seal by gluing all the seams 117, 114 of the rod 110 located in a part waterproof of it.

De ce fait, les seules coutures restant à étancher sont celles 141 reliant la guêtre à la tige, ces coutures étant étanchées de façon connue en soi par une application de colle ou de film étanche sur le côté interne de la tige 110.Therefore, the only seams remaining to be sealed are those 141 connecting the gaiter to the rod, these seams being sealed in a manner known per se by applying an adhesive or film watertight on the internal side of the rod 110.

Que ce soit dans le mode de réalisation de la figure 1 ou de la figure 4, le collage du renfort externe 20, 120 sur la tige sur une grande surface dudit renfort permet, par une construction simple et peu chère, de garantir une bonne étanchéité de la chaussure tout en étant, de façon surprenante, suffisamment résistant pour résister aux efforts notamment de traction s'exerçant sur ledit renfort lors du serrage d'au moins sa partie supérieure 50, 150.Whether in the embodiment of FIG. 1 or of FIG. 4, the bonding of the reinforcement external 20, 120 on the rod over a large area of said reinforcement allows, by a construction simple and inexpensive, to guarantee a good seal of the shoe while being, so surprising, strong enough to withstand the tensile stresses exerted in particular on said reinforcement when tightening at least its upper part 50, 150.

Dans le mode de réalisation montré à la figure 5, la chaussure se compose d'une semelle externe 230, d'une tige mi-haute 210 comportant à l'arrière un contrefort talon 213 assemblé à ladite tige 210 par des coutures 214, la tige 210 recouvrant le contrefort talon 213 par l'extérieur.In the embodiment shown in Figure 5, the shoe consists of a sole external 230, of a mid-high rod 210 comprising at the rear a heel stiffener 213 assembled at said rod 210 by seams 214, rod 210 covering the heel counter 213 by outside.

De même que dans les modes de réalisation précédents, un renfort supplémentaire 220 comportant une zone talon 221 est collé à l'arrière sur le contrefort talon 213, recouvrant les coutures 214 d'assemblage de ce dit contrefort à la tige, réalisant ainsi leur étanchage.As in the previous embodiments, an additional reinforcement 220 having a heel area 221 is glued to the back on the heel counter 213, covering the stitching 214 of assembly of this said buttress to the rod, thus achieving their sealing.

La seule différence de ce mode de réalisation par rapport aux modes de réalisation précédents est que le renfort 220 est solidaire de la semelle externe 230 et est donc collé simultanément avec celle-ci à la tige.The only difference of this embodiment compared to the embodiments previous is that the reinforcement 220 is integral with the outer sole 230 and is therefore glued simultaneously with this to the rod.

Dans ce cas le renfort 220 est réalisé dans le même matériau que la semelle externe 230. Ladite semelle 230 peut également être réalisée en deux parties, à savoir une partie arrière rigide et sensiblement non flexible qui est alors solidaire du renfort 220, et une partie avant plus souple, comme décrit dans le FR 2 743 989.In this case, the reinforcement 220 is made of the same material as the outer sole 230. Said sole 230 can also be made in two parts, namely a rear part rigid and substantially non-flexible which is then secured to the reinforcement 220, and a front part more flexible, as described in FR 2,743,989.
