Abstract

A sports boot has the two side-pieces (110) of its upper joined by a bootlace (4) passed through loops (30) of a supple material which is resistant to traction. Each loop contains a guide with an anti-friction surface (310) for the lace, possessing sufficient rigidity to prevent it from being deformed by the pressure of the lace. Each loop is made from a strip of a textile material, while its guide is made from a low-friction plastic such as PTFE, PTCFE, FEP, nylon, polyamide, polyethylene or polyacetal.

Description

La présente invention se rapporte au domaine de la chaussure de sport ; en particulier le domaine de la chaussure technique du type randonnée, surf de neige, patin en ligne, parapente, etc.The present invention relates to the field of sports shoes; in particularly the field of technical footwear of the hiking, surfing type snow, inline skating, paragliding, etc.

Une chaussure de sport du type précité comprend traditionnellement une semelle et une tige munie d'une ouverture pour le passage du pied et comportant de part et d'autre de cette ouverture des moyens de renvoi ou passants qui coopèrent avec un ou plusieurs moyens de serrage tel qu'un lacet pour assurer par serrage, la fermeture partielle de l'ouverture.A sports shoe of the aforementioned type traditionally comprises a sole and an upper provided with an opening for the passage of the foot and comprising on either side of this opening return means or passers-by who cooperate with one or more tightening means such as a lace to ensure by tightening, the partial closing of the opening.

Pour certaines chaussures, les moyens de renvoi localisés sur le dessus d'une partie de la tige subissent des pressions dans diverses circonstances. Certaines chaussures de surf des neiges, par exemple, sont destinées à coopérer avec une fixation comprenant des sangles transversales qui exercent une pression sur le dessus du pied ; et par conséquent, compriment les moyens de renvoi ou passants. On a constaté que des passants encombrants et rigides tels que des crochets, boucles ou oeillets métalliques ou plastiques peuvent occasionner des points durs ; ce qui peut engendrer un problème de douleur du pied et aussi déformer la sangle par endroit de façon plus ou moins permanente.For certain shoes, the return means located on the top of a part of the stem are under pressure under various circumstances. Some snowboard boots, for example, are intended to cooperate with a binding comprising transverse straps which exert pressure on the above the foot; and therefore compress the referral means or passersby. It has been found that bulky and rigid passers-by such as metal or plastic hooks, loops or eyelets can cause hard spots; which can cause a foot pain problem and also deform the strap in places more or less permanently.

Le document EP-A-0717942 décrit un passant pour lacet constitué d'une enveloppe extérieure et d'un viseur.The document EP-A-0717942 describes a passer-by for lace made up of an external envelope and a viewfinder.

Certaines chaussures de randonnée ou autres, qui présentent un dispositif de serrage interne d'une partie de la tige, rencontrent un problème analogue. Dans ce cas, la partie interne de tige comprend des moyens de renvoi qui subissent une pression de la part d'une partie externe de tige après serrage de cette dernière par différents moyens ( laçage, velcro, fermeture à glissière,..). Ces pressions engendrent à nouveau des problèmes d'inconfort ou de déformation de la chaussure qu'il est préférable d'éviter.Certain hiking shoes or others, which have a device for internal tightening of part of the rod, encounter a similar problem. In in this case, the internal part of the rod comprises return means which undergo a pressure from an external rod part after tightening of the latter by different means (lacing, velcro, zipper, ..). These pressures again cause discomfort or distortion of the shoe that is best avoided.

Pour remédier à ce problème, il est connu d'utiliser des passants souples et résistants à la traction sous forme de bandes textiles repliées en forme de boucle et reliées à la tige pour limiter leur encombrement et favoriser leur déformation sous l'effet d'une pression extérieure.To remedy this problem, it is known to use flexible loops and tensile-resistant in the form of textile bands folded into a loop and connected to the rod to limit their size and promote their deformation under the effect of external pressure.

Un exemple d'un tel emploi est donné dans le document FR-A-2 726 440 qui concerne une chaussure de sport comprenant un dispositif de serrage interne au niveau du cou-de-pied et une tige externe de protection contre les agressions extérieures qui enserre le dispositif interne et exerce donc des pressions sur les moyens de renvoi du dispositif.An example of such use is given in document FR-A-2 726 440 which relates to a sports shoe comprising an internal tightening device at the instep level and an external rod for protection against attack which encloses the internal device and therefore exerts pressure on the means of returning the device.

Ces moyens de renvoi ne donnent pas toutefois entière satisfaction.These removal means are not entirely satisfactory, however.

En raison de la nature et des caractéristiques de la boucle ; en particulier de sa texture et de sa souplesse, le rendement de serrage n'est pas optimum. Les frottements subits par le lacet sont élevés. Par ailleurs, le lacet déforme la bande en rétrécissant sa largeur en raison de l'angle de renvoi ce qui crée des frottements supplémentaires et peut conduire à une usure prématurée de la boucle, voire à la rupture de celle-ci.Due to the nature and characteristics of the loop; especially from his texture and flexibility, the clamping performance is not optimum. The friction undergone by the lace is high. In addition, the lace distorts the strip narrowing its width due to the deflection angle which creates additional friction and can lead to premature wear of the loop, or even at the break of it.

Le but de la présente invention est donc d'apporter une solution satisfaisante aux inconvénients exposés ci-dessus.The aim of the present invention is therefore to provide a satisfactory solution to the disadvantages set out above.

Ce but est atteint en utilisant un moyen ou élément de renvoi qui comprend un élément de guidage relié à ladite boucle et présentant une surface de glissement pour le passage du moyen de serrage à l'intérieur de la boucle selon un plan de passage P ; l'élément de guidage présentant une rigidité suffisante dans le plan P pour résister à la déformation lors de la mise sous tension du moyen de serrage.This object is achieved by using a referral means or element which includes a guide element connected to said loop and having a surface of sliding for the passage of the clamping means inside the loop according to a passage plan P; the guide element having sufficient rigidity in plane P to resist deformation when the power is turned on clamping means.

Un tel moyen de renvoi présente les avantages d'un encombrement limité et d'une souplesse importante tout en réduisant les frottements avec le lacet ; lui assurant ainsi un bon rendement et une longévité importante.Such a return means has the advantages of a limited size and significant flexibility while reducing friction with the lace; him thus ensuring a good yield and a long service life.

D'autres caractéristiques et avantages de l'invention ressortiront des caractéristiques de la description détaillée suivante illustrée par les dessins annexés dont

    • Other characteristics and advantages of the invention will emerge from the characteristics of the following detailed description illustrated by the accompanying drawings, of which
  • Figure 1 shows a schematic example of a surf boot engaged in a strap fastening;
  • Figure 2 is a simplified perspective view of a shoe according to the invention;

    • En se référant à la figure 1, il s'agit d'un exemple d'application d'une chaussure de l'invention qui permet de mettre en évidence l'un des problèmes techniques déjà cités.Referring to Figure 1, this is an example of application of a shoe of the invention which makes it possible to highlight one of the problems techniques already mentioned.

    La chaussure 1 est une botte de surf des neiges comprenant une tige souple ou semi-souple 10 et un dispositif de serrage 11 de la tige. Dans la configuration représentée, la botte est en position dans une fixation de surf traditionnelle 2 qui a la particularité de comprendre une embase 20 destinée à être rattachée à une planche (non représentée) et deux sangles 20, 21 qui maintiennent fermement la botte dans l'embase 20. Shoe 1 is a snowboard boot comprising a flexible upper or semi-flexible 10 and a clamping device 11 of the rod. In the configuration shown, the boot is in position in a traditional surf binding 2 which has the particularity of comprising a base 20 intended to be attached to a board (not shown) and two straps 20, 21 which firmly hold the boot in base 20.

    Les sangles 20, 21 exercent donc une pression importante localement sur le dispositif de serrage ; d'où la nécessité de prévoir des moyens de renvoi adaptés pour éviter les risques d'inconfort et d'autres précédemment cités.The straps 20, 21 therefore exert significant pressure locally on the clamping device; hence the need to provide suitable return means to avoid the risks of discomfort and others previously mentioned.

    Comme le montre la figure 2, la solution passe par l'utilisation de moyens de renvoi 3 comprenant une boucle fermée 30 en matériau souple et résistant à la traction.As shown in Figure 2, the solution involves the use of means of return 3 comprising a closed loop 30 made of flexible material resistant to traction.

    La chaussure de la figure 2 a été volontairement simplifiée pour ne faire ressortir que l'essentiel de l'invention. La tige présente une portion 110 ; en l'occurrence portion antérieure ou empeigne, qui est munie d'une ouverture 12 délimitant deux quartiers 110a, 110b à serrer.The shoe of figure 2 has been deliberately simplified so as not to bring out that the essence of the invention. The rod has a portion 110; in the anterior portion or upper, which is provided with an opening 12 delimiting two quarters 110a, 110b to be tightened.

    Les moyens de renvoi sont répartis de façon opposée de part et d'autre de l'ouverture 12 sur chaque quartier 110a, 110b.The return means are distributed in opposite directions on either side of opening 12 on each quarter 110a, 110b.

    Un moyen de serrage tel qu'un lacet 4 est prévu pour circuler au travers de chaque boucle 30 selon un circuit croisé et alternant un moyen de renvoi et son opposé, par exemple ; ce qui provoque le rapprochement des quartiers l'un vers l'autre.A tightening means such as a lace 4 is provided to circulate through each loop 30 according to a crossed circuit and alternating a return means and its opposite, for example; which brings the neighborhoods towards one the other.

    Une telle méthode de laçage n'est pas la seule réalisation possible, bien entendu.Such a lacing method is not the only possible realization, well heard.

    La figure 3 qui illustre l'art antérieur, montre le défaut majeur provoqué sur le moyen de renvoi. La boucle 30 qui se présente sous la forme d'une portion de sangle reliée à la portion de tige 110, subit une traction importante de la part du moyen de serrage ou lacet 4. L'angle de renvoi 'a' étant relativement faible lorsque les boucles sont rapprochées l'une de l'autre, il y a déformation de la sangle par réduction de largeur et donc apparition de forces de frottements élevées qui s'opposent au glissement du lacet dans la boucle. Ceci peut avoir pour conséquence d'affecter l'homogénéité du serrage, en particulier en bout, lorsque l'on tire sur les extrémités du lacet. Il faut ensuite reprendre le serrage en tirant à nouveau sur chaque brin de lacet compris entre deux boucles. L'opération de laçage peut ainsi devenir fastidieuse et longue.FIG. 3 which illustrates the prior art, shows the major fault caused on the means of reference. The loop 30 which is in the form of a portion of strap connected to the rod portion 110, undergoes significant traction from the tightening means or lace 4. The angle of return 'a' being relatively small when the loops are brought together, there is deformation of the strap by reduction of width and therefore appearance of frictional forces which oppose the sliding of the lace in the loop. This may have consequence of affecting the uniformity of the tightening, in particular at the end, when we pull on the ends of the lace. Then tighten again by pulling new on each lace strand between two loops. The operation of lacing can thus become tedious and long.

    Ces frottements peuvent conduire à une usure prématurée de la sangle de la boucle jusqu'à rupture possible.This friction can lead to premature wear of the strap of the loop until break possible.

    La figure 4 montre la solution de l'invention. Le moyen de renvoi 3 représenté comprend une boucle fermée identique à celle de la figure 3 mais qui est associée à un élément de guidage 31.Figure 4 shows the solution of the invention. Means of reference 3 shown includes a closed loop identical to that of Figure 3 but which is associated with a guide element 31.

    Comme le montre la figure 5, l'élément de guidage 31 présente une surface de glissement 310 pour le passage du moyen de serrage 4 à l'intérieur de la boucle souple 30 selon un plan de passage P. Cette surface a pour fonction de faciliter le passage et le glissement du moyen de serrage 4. Le plan P est pris pour référence afin de faciliter les explications et correspond approximativement au plan du trajet du lacet 4 au voisinage de chaque moyen de renvoi. Bien entendu, le plan P peut varier d'une région à l'autre de la chaussure en raison de la forme incurvée de la tige.As shown in FIG. 5, the guide element 31 has a surface of sliding 310 for the passage of the clamping means 4 inside the loop flexible 30 along a passage plane P. The function of this surface is to facilitate the passage and sliding of the clamping means 4. The plane P is taken for reference in order to facilitate the explanations and corresponds approximately to the plan of the path of the lace 4 in the vicinity of each return means. Of course, the plan P may vary from region to region of shoe due to the curved shape of the stem.

    L'élément de guidage a pour autre caractéristique importante de présenter une certaine rigidité dans le plan P ainsi défini. Cette rigidité doit être telle que la mise sous tension du moyen de serrage ne puisse provoquer la déformation latérale de l'élément de guidage et par conséquent n'affecte la largeur de la sangle de la boucle. Ainsi, l'élément de guidage aura une largeur au moins égale à celle de la boucle.Another important characteristic of the guide element is that it has a certain rigidity in the plane P thus defined. This rigidity must be such that the setting under tension of the clamping means cannot cause lateral deformation of the guide element and therefore does not affect the width of the strap of the loop. Thus, the guide element will have a width at least equal to that of the loop.

    Les figures 6 et 7 montrent la forme particulière de la surface de glissement destinée à guider le moyen de serrage 4 au glissement. La surface de glissement de l'élément de guidage présente une génératrice de forme convexe dans le plan de passage P et une génératrice de forme concave dans le plan P' perpendiculaire à P. La concavité dans le plan P' favorise la tenue et le guidage du lacet au contact de l'élément. Le glisssement est quant à lui amélioré par la convexité selon P.Figures 6 and 7 show the particular shape of the sliding surface intended to guide the clamping means 4 to sliding. The sliding surface of the guide element has a generator of convex shape in the plane of passage P and a generator of concave shape in the plane P 'perpendicular to P. The concavity in the plane P 'favors the holding and guiding of the lace in contact with item. The sliding is improved by the convexity according to P.

    La forme de gorge ainsi définie en termes généraux n'est toutefois pas la seule possible. On peut aussi prévoir une forme tubulaire de la surface afin de garantir un guidage du lacet dans toute direction radiale.The throat shape thus defined in general terms is not, however, the only one possible. It is also possible to provide a tubular shape of the surface in order to guarantee yaw guidance in any radial direction.

    De préférence, les épaisseurs des bords latéraux 310a, 310b de l'élément de guidage seront prévues en fonction du matériau utilisé de façon à présenter une certaine déformabilité en compression dans la direction selon le plan P'. De ce fait, le phénomène de point dur déjà évoqué disparait complètement.Preferably, the thicknesses of the lateral edges 310a, 310b of the element guidance will be provided depending on the material used so as to present a some deformability in compression in the direction along the plane P '. From this fact, the hard point phenomenon already mentioned disappears completely.

    Selon une autre caractéristique de l'invention, l'élément de guidage présente une lumière 311 permettant d'assurer le passage de la portion de sangle 30 au travers de l'élément de guidage et sa liaison avec l'élément de guidage. La lumière traverse l'élément d'un bord 310a à l'autre 310b. Ce moyen de liaison a pour avantage d'être le plus résistant et le plus simple pouvant être mis en oeuvre. Toutefois d'autres moyens de liaison peuvent être envisagés comme le rivetage, clippage/pincement, agrafage,....According to another characteristic of the invention, the guide element has a light 311 making it possible to pass the strap portion 30 to the through the guide element and its connection with the guide element. The light passes through the element from one edge 310a to the other 310b. This means of connection has the advantage of being the most resistant and the simplest that can be put in artwork. However, other means of connection can be envisaged such as riveting, clipping / pinching, stapling, ....

    Comme le montrent les diverses figures, les moyens de renvoi 3 sont répartis de façon opposée sur chaque quartier 110a, 110b et sont agencés de manière que chaque boucle présente une partie reliée sur un des quartiers et une partie incluant ledit élément de guidage qui déborde du quartier sur l'ouverture 12.As the various figures show, the return means 3 are distributed opposite on each quarter 110a, 110b and are arranged so that each loop has a part connected to one of the districts and a part including said guide element which projects beyond the quarter on the opening 12.

    De la sorte, l'élément de guidage prend position dans l'épaisseur du quartier en cas de pression exercée sur le dispositif de serrage par un élément extérieur ; et ce en partie grâce à la souplesse de la boucle. On diminue ainsi le risque de point dur.In this way, the guide element takes position in the thickness of the quarter in the event of pressure exerted on the clamping device by an external element; and this in part thanks to the flexibility of the loop. This reduces the risk of point hard.

    De préférence, la portion de sangle est choisie en matériau textile en raison de ses propriétés de souplesse et de résistance en traction. Dans certains cas, on pourrait éventuellement envisager d'utiliser des portions de bandes en caoutchouc ou en cuir. La portion de sangle est reliée à la tige par couture, de préference, ou encore par d'autres moyens tels que rivetage, agrafage, ou une combinaison de plusieurs moyens. Il rentre aussi dans la cadre de l'invention de prévoir une portion de sangle comme une partie continue d'un morceau de tissu de la tige.Preferably, the strap portion is chosen from textile material because of its flexibility and tensile strength properties. In some cases, could possibly consider using portions of strips in rubber or leather. The strap portion is connected to the upper by sewing, preference, or by other means such as riveting, stapling, or a combination of several means. It is also part of the invention of provide a portion of strap as a continuous part of a piece of fabric of the stem.

    L'élément de guidage est, bien entendu, constitué dans un matériau de faible coefficient de frottement. Différents matériaux sont susceptibles de convenir. Avantageusement, l'élément de guidage est constitué dans un matériau plastique choisi parmi les PTFE, les PTFCE, les FEP, les nylons, les polyamides, les polyéthylènes, les polyacéthals.The guide element is, of course, made of a material of low coefficient of friction. Different materials are likely to be suitable. Advantageously, the guide element is made of a plastic material chosen from PTFE, PTFCE, FEP, nylons, polyamides, polyethylenes, polyacethals.
