Abstract

PROBLEM TO BE SOLVED: To easily fix boots to a surfer's feet, easily adjust the boots to the feet, and hold the formation of uppers or an inner shoe by providing a layer formed of material with a low coefficient of friction in an area where a cross flap overlaps a small tongue-like member. SOLUTION: Uppers 4 of boots 1 are covered with or formed of deformable material such as leather, cloth, woven fabric or the like. A cross flap 47 and a small tongue-like member 6 are covered with the above material and at least one of these elements is provided with a layer 11 of material with a low coefficient of friction in an area where they overlap each other. To be precise, the material layer 11 is disposed and fixed on the cross flap 4' on the side directed toward the small tongue-like member 6. Further, the material layer 11 is extended only to a high part 12 of the boots 1 corresponding to the leg lower part of the surfer. By this arrangement, the use of a strap type device 7 can obtain different holding members between a lower part 13 surrounding the foot and a higher part 12 surrounding the lower leg part.

Description

La présente invention concerne une botte de surf de neige dont la tige se ferme à l'aide de deux rabats transversaux qui viennent en recouvrement d'une languette qui s'étend sur la partie antérieure du pied et du bas de jambe du surfeur.The present invention relates to a snowboard boot whose stem is closed by means of two transverse flaps which overlap with a tongue which extends over the anterior part of the foot and the lower leg of the surfer.

La quasi totalité des bottes de surf de neige connues présente ce type de structure de tige avec un système de fermeture à laçage, que la botte soit obtenue d'une pièce, c'est-à-dire avec une enveloppe extérieure pourvue de rembourrages de confort, ou en deux pièces, c'est-à-dire avec une enveloppe extérieure et un chausson amovible de confort. Dans ces bottes de surf, la tige est conçue pour présenter une possibilité de flexion relativement importante vers l'avant ainsi qu'une certaine résistance au mouvement à partir d'une position fléchie. En effet, les pieds du surfeur étant en position transversale par rapport au surf, la nécessité de ramener la verticale du centre de gravité sur l'axe central du surf impose une flexion des chevilles. De plus, à partir de cette attitude de base, chevilles fléchies, l'absorption du relief du sol et les flexions-extensions doivent être possibles sans que les jambes se heurtent à une trop grande rigidité de la tige des bottes, ou inversement, qu'elles ne rencontrent aucune résistance du fait qu'une trop grande laxité de la tige.Almost all known snowboard boots have this type of rod structure with a lacing closure system, that the boot is obtained from a piece, that is to say with an outer casing provided with padding. comfort, or in two pieces, that is to say with an outer shell and a removable boot comfort. In these surf boots, the upper is designed to have a relatively large forward flexing capability as well as some resistance to movement from a bent position. Indeed, the feet of the surfer being in position transverse to the surf, the need to bring the vertical center of gravity on the central axis of the surf imposes bending of the ankles. Moreover, from this basic attitude, bent dowels, the absorption of the ground relief and the flexion-extensions must be possible without the legs colliding with too much rigidity of the stem of the boots, or conversely, that they do not meet any resistance because too much laxity of the stem.

Pour ces différentes raisons, les tiges des bottes de surf sont généralement construites et habillées avec des matériaux relativement souples, assez facilement déformables, mais pratiquement pas élastiques tels que du cuir, des toiles, des tissus,...etc., qui sont éventuellement enduits pour des questions d'étanchéité ou de protection à l'usure. Ces matériaux permettent par ailleurs de multiples combinaisons d'assemblage et ainsi des constructions de tiges très diverses et plus ou moins souples, adaptées en fonction de la pratique pour laquelle les bottes de surf sont plus spécialement destinées, par exemple pour des pratiques sur tous les terrains et toutes les neiges, ou sur des pistes telles que celles aménagées en forme de demi tube.For these reasons, the stems of the surf boots are generally constructed and dressed with relatively soft materials, quite easily deformable, but practically not elastic such as leather, canvases, fabrics, etc., which are possibly coatings for sealing or protection against wear. These materials also allow multiple combinations of assembly and thus very diverse and more or less flexible rod constructions, adapted according to the practice for which the surf boots are more specifically intended, for example for practices on all terrain and all snow, or tracks such as those arranged in the form of a half tube.

Par ailleurs, le choix de matériaux dont la texture de surface paraît nature et rustique répond à la mode actuelle des surfeurs en matière d'habillement et ajoute une impression de confort à la botte.In addition, the choice of materials whose surface texture looks natural and rustic meets the current fashion of surfers in terms of clothing and adds a feeling of comfort to the boot.

Les bottes de surf ainsi construites présentent cependant l'inconvénient d'être relativement difficiles à assujettir au pied notamment au niveau de leur tige à l'aide des rabats transversaux qui viennent en recouvrement de la languette. En effet, les matériaux précités tels que le cuir, les tissus, les toiles,...etc., qui constituent et/ou habillent la tige présentent dans leur état habituel une texture de surface volontairement rugueuse et peu glissante qui augmente considérablement le frottement entre la languette et les rabats transversaux. La fermeture de la tige requiert par conséquent d'exercer un effort de serrage relativement important sur le système de laçage pour rapprocher les rabats transversaux entre eux et ainsi faire plaquer la languette contre le pied et/ou le bas de jambe du surfeur. Cette nécessité d'un serrage énergique est non seulement contraignante mais également la source de blessures aux mains car le lacet du système de laçage n'offre qu'une très petite surface de prise alors que l'effort de traction qui lui est appliqué est important. Le même problème se pose avec les chaussures dans le cas de bottes en deux pièces.The surf boots thus constructed have the disadvantage of being relatively difficult to fasten to the foot especially at their stem with the transverse flaps that overlap the tongue. Indeed, the abovementioned materials such as leather, fabrics, canvases, etc., which constitute and / or dress the stem present in their usual state a voluntarily rough and slightly slippery surface texture which considerably increases the friction between the tongue and the transverse flaps. The closure of the rod therefore requires a relatively large tightening force on the lacing system to bring the transverse flaps together and thus press the tab against the foot and / or the lower leg of the surfer. This need for energetic tightening is not only restrictive but also the source of hand injuries because the lace of the lacing system offers only a very small grip surface while the effort of traction applied to it is important. The same problem arises with shoes in the case of two-piece boots.

La présente invention a pour but de faciliter l'assujettissement de la botte de surf au pied du surfeur tout en conservant une construction de tige ou de chausson faite avec des matériaux déformables capables de se conformer aisément au pied, tels que du cuir, des toiles, des tissus,...etc. Pour atteindre ce but, l'invention propose de réduire considérablement la valeur du frottement entre les rabats et la languette qui assurent la fermeture de la botte de surf ou du chausson.The present invention aims to facilitate the subjection of the surf boot at the foot of the surfer while maintaining a rod or shoe construction made of deformable materials capable of easily conforming to the foot, such as leather, canvases , fabrics, ... etc. To achieve this goal, the invention proposes to significantly reduce the value of the friction between the flaps and the tongue that ensure the closure of the surf boot or slipper.

A cet effet, la tige de la botte de surf est dotée, dans la zone où les rabats transversaux chevauchent la languette, d'au moins une couche de matière à faible coefficient de frottement, en particulier par rapport aux matériaux qui l'habillent. Selon diverses réalisations de l'invention, il s'agit d'un film ou d'une pellicule que l'on dépose par exemple par enduction, ou d'une feuille d'un matériau présentant une surface glissante que l'on rapporte juste dans la zone de recouvrement des rabats sur la languette. Cette couche de matière est par ailleurs disposée indifféremment sur les rabats et/ou sur la languette. Selon diverses constructions, la couche de matière s'étend sur toute la zone où les rabats transversaux chevauchent la languette ou seulement en partie, notamment pour obtenir un maintien différencié par exemple entre le pied et le bas de jambe du surfeur.For this purpose, the upper of the surf boot is provided, in the area where the transverse flaps overlap the tongue, at least one layer of low friction material, particularly with respect to the materials that dress it. According to various embodiments of the invention, it is a film or film that is deposited for example by coating, or a sheet of a material having a slippery surface that is reported just in the overlap area of the flaps on the tongue. This layer of material is also arranged indifferently on the flaps and / or on the tongue. According to various constructions, the layer of material extends over the entire area where the transverse flaps overlap the tongue or only partially, especially to obtain a differentiated support for example between the foot and the lower leg of the surfer.

La même construction peut être appliquée au chausson dans le cas d'une chaussure en deux pièces, au moins un des rabats, ou la languette s'il y en a une, étant muni d'une telle couche à faible coefficient de frottement.The same construction can be applied to the shoe in the case of a shoe in two pieces, at least one of the flaps, or the tongue if there is one, being provided with such a low friction layer.

Par exemple une matière à faible coefficient de frottement a été utilisée dans le document EP-A-0 551 704 pour réduire le frottement entre les rabats de la manchette d'un patin en ligne et la languette de la botte détachable du patin.For example, a low friction material has been used in EP-A-0 551 704 to reduce the friction between the flaps of the in-line pad cuff and the tongue of the pad removable boot.

L'invention sera du reste mieux comprise en se reportant à la description qui va suivre en référence au dessin annexé montrant, à titre d'exemple, deux modes de réalisation d'une botte de surf qui en est dotée.The invention will be better understood by referring to the description which follows with reference to the accompanying drawing showing, by way of example, two embodiments of a surf boot which is provided.

La figure 1 montre, vue en perspective de trois quart avant, une botte de surf obtenue en une pièce et dont la tige comporte une couche de matière à faible coefficient de frottement selon l'invention.FIG. 1 shows, in perspective three quarter front view, a surf boot obtained in one piece and whose upper comprises a layer of material with a low coefficient of friction according to the invention.

La figure 2 représente, vue de dessus, la botte de surf de la figure 1 en position de fermeture.Figure 2 shows, viewed from above, the surf boot of Figure 1 in the closed position.

La figure 3 illustre, vue de dessus, une botte de surf comportant un chausson et une enveloppe extérieure, cette dernière étant dotée au niveau de sa tige d'une couche de matière à très faible coefficient de frottement.FIG. 3 is a plan view of a surf boot comprising a liner and an outer casing, the latter being provided at its upper with a layer of material with a very low coefficient of friction.

La botte de surf 1, représentée aux figures 1 et 2, est obtenue en une pièce, c'est-à-dire avec une enveloppe extérieure 2 et un rembourrage de confort 3. Ce dernier assure l'interface entre l'enveloppe extérieure et l'ensemble pied-bas de jambe du surfeur indiqué par la référence numérique 5 sur la figure 2. De manière connue en soi, l'enveloppe extérieure 2 est munie d'une semelle 10 et comporte une tige 4 qui se ferme à l'aide de deux rabats transversaux 4' qui viennent en recouvrement d'une languette 6 qui s'étend sur la partie antérieure du pied et du bas de jambe 5 du surfeur. Un système de fermeture à laçage 7, comprenant un lacet 8 et des passants 9 disposés sur les rabats 4' de la tige 4, est prévu pour permettre l'ajustage et l'assujettissement de la botte 1 sur le pied et le bas de jambe 5 du surfeur.The surf boot 1, shown in FIGS. 1 and 2, is obtained in one piece, that is to say with an outer shell 2 and a comfort padding 3. The latter provides the interface between the outer shell and the foot-lower leg of the surfer indicated by the reference numeral 5 in Figure 2. In known manner, the outer casing 2 is provided with a sole 10 and has a rod 4 which closes to the using two transverse flaps 4 'which overlap with a tongue 6 which extends over the anterior part of the foot and the lower leg 5 of the surfer. A lacing closure system 7 comprising a lace 8 and passers 9 arranged on the flaps 4 'of the rod 4, is provided to allow the adjustment and securing of the boot 1 on the foot and lower leg 5 of the surfer.

Dans ce but, la tige 4 de la botte 1 est avantageusement habillée et/ou construite avec des matériaux déformables tels que du cuir, des tissus, de la toile,...etc., qui présentent ce que l'on appelle communément du prêtant, c'est-à-dire qui peuvent dans une certaine mesure s'étirer, s'étendre avant l'apparition d'un comportement élastique.For this purpose, the upper 4 of the boot 1 is advantageously dressed and / or constructed of deformable materials such as leather, fabrics, canvas, etc., which have what is commonly known as lending, that is to say which can to a certain extent stretch, extend before the appearance of elastic behavior.

Pour cette raison, entre autres, les rabats transversaux 4' et la languette 6 sont habillés de ces matériaux et, conformément à l'invention, au moins l'un de ces éléments est doté d'une couche 11 de matière à faible coefficient de frottement dans la zone où ils se recouvrent. Plus précisément, dans le présent exemple de réalisation, la couche 11 de matière est disposée-fixée sur les rabats transversaux 4', du côté dirigé vers la languette 6. Par ailleurs, la couche 11 s'étend uniquement dans la partie haute 12 de la botte 1 en correspondance du bas de jambe du surfeur, c'est-à-dire au-dessus de la partie basse 13 qui chausse le pied proprement dit.For this reason, inter alia, the transverse flaps 4 'and the tongue 6 are dressed with these materials and, in accordance with the invention, at least one of these elements is provided with a layer 11 of material with a low coefficient of friction in the area where they overlap. More specifically, in the present embodiment, the layer 11 of material is arranged-fixed on the transverse flaps 4 ', the side directed towards the tongue 6. Moreover, the layer 11 extends only in the upper part 12 of the boot 1 corresponding to the lower leg of the surfer, that is to say above the lower part 13 which shoes the foot itself.

Par ces dispositions, la mise en oeuvre du système de laçage 7 permet d'obtenir un maintien différencié entre la partie basse 13 qui entoure le pied et la partie haute 12 qui entoure le bas de jambe, car la couche 11 favorise le glissement des rabats 4' sur la languette 6 uniquement à son emplacement. Par conséquent, le serrage de la partie haute 12 s'en trouve facilité.By these provisions, the implementation of the lacing system 7 provides a differentiated maintenance between the lower part 13 which surrounds the foot and the upper part 12 which surrounds the lower leg, because the layer 11 promotes the sliding of the flaps 4 'on the tongue 6 only at its location. Therefore, the tightening of the upper part 12 is facilitated.

La botte de surf 31 représentée à la figure 3 se distingue de la botte 1 précédente essentiellement par le fait qu'elle est obtenue globalement en deux pièces principales, soit une enveloppe extérieure 32 et un chausson de confort amovible 33. Tous les autres composants étant identiques à ceux de la botte de surf 1 des figures 1 et 2, leur description et/ou leur fonctionnement ne sont donc pas repris.The surf boot 31 shown in FIG. 3 differs from the previous boot 1 essentially in that it is generally obtained in two main parts, namely an outer shell 32 and a removable comfort boot 33. All the other components being identical to those of the surf boot 1 of Figures 1 and 2, their description and / or operation are not included.

Dans un tel cas de construction le chausson de confort amovible 33 peut, lui-même, être doté d'une couche de matière 11 à très faible coefficient de frottement dans sa zone de fermeture.In such a case of construction the removable comfort liner 33 may, itself, be provided with a layer of material 11 with a very low coefficient of friction in its closure zone.

Bien entendu, le chausson 33 peut se fermer comme la botte de surf 31, c'est-à-dire avec une paire de rabats transversaux 34 qui recouvrent une languette 36. Il peut également se fermer simplement à l'aide de deux rabats 34 qui se recouvrent mutuellement, c'est-à-dire sans présence d'une languette 36. Dans ce cas, la couche de matière 11 à faible coefficient de frottement est fixée sur l'un seulement des rabats 34 dans la zone de chevauchement.Of course, the boot 33 can be closed like the surf boot 31, that is to say with a pair of transverse flaps 34 which cover a tongue 36. It can also be closed simply by means of two flaps 34 which overlap each other, i.e. without the presence of a tongue 36. In this case, the layer of material 11 with a low coefficient of friction is fixed on only one of the flaps 34 in the overlap zone.

Selon une variante de réalisation de l'invention, une couche de matière 11 à faible coefficient de frottement est disposée entre la languette 36 du chausson 33 et la languette 6 et/ou les rabats 4' de la tige 4 de la botte de surf.According to an alternative embodiment of the invention, a layer of material 11 with a low coefficient of friction is disposed between the tongue 36 of the shoe 33 and the tongue 6 and / or the flaps 4 'of the rod 4 of the surf boot.

Encore, le chausson de confort amovible 33 peut être prévu avec une zone de fermeture disposée plus ou moins latéralement à la tige.Again, the removable comfort boot 33 may be provided with a closure zone disposed more or less laterally to the rod.

Il est bien entendu que la botte de surf 1 ou 31 peut être réalisée d'autres manières sans pour cela sortir du cadre de l'invention. Ainsi, par exemple, la couche 11 de matière à faible coefficient de frottement peut être fixée sur la languette 6, du côté dirigé vers les rabats 4', et/ou s'étendre sur toute la zone où il y a chevauchement entre lesdits rabats 4' et ladite languette 6. Encore, la couche 11 de matière à faible coefficient de frottement peut être mise en oeuvre uniquement sur un des deux rabats transversaux 4'.It is understood that the surf boot 1 or 31 can be made in other ways without departing from the scope of the invention. Thus, for example, the layer 11 of low friction material may be attached to the tongue 6, the side directed to the flaps 4 ', and / or extend over the entire area where there is overlap between said flaps 4 'and said tongue 6. Again, the layer 11 of low friction material can be implemented only on one of the two transverse flaps 4 '.

Enfin, la couche 11 de matière à faible coefficient de frottement peut être constituée par le dépôt d'un film sur la zone où les rabats 4' chevauchent la languette 6 et la réalisation de ce dépôt est, par exemple, obtenue par enduction, trempage,...etc. La couche 11 peut aussi être constituée par une feuille ou une bande plus ou moins étroite, présentant une surface glissante, qui est rapportée sur les rabats 4' et/ou sur la languette 6 dans la zone de recouvrement.Finally, the layer 11 of low friction material may be constituted by the deposition of a film on the area where the flaps 4 'overlap the tongue 6 and the realization of this deposit is, for example, obtained by coating, soaking ... etc. The layer 11 may also be constituted by a sheet or a more or less narrow strip, having a slippery surface, which is attached to the flaps 4 'and / or the tongue 6 in the overlap area.

Par couche à faible coefficient de frottement on entend une couche dont le coefficient de frottement est plus faible que celui des matériaux environnants de façon à faciliter le glissement mutuel desdits matériaux.By low coefficient of friction layer is meant a layer whose coefficient of friction is lower than that of the surrounding materials so as to facilitate the mutual sliding of said materials.
