Description

La présente invention se rapporte au domaine de la chaussure de sport, plus particulièrement à celles présentant une partie de tige montante telles que les bottes de surf des neiges, les chaussures de randonnées, les chaussures destinées à des pratiques sportives spécifiques comme le parapente, le patin en ligne ou autres.The present invention relates to the field of footwear sports, especially those with a part rising stem such as snowboard boots, hiking shoes, shoes intended for specific sports such as paragliding, skating line or others.

Le problème que l'on rencontre dans le serrage des chaussures à tige montante provient du fait que la partie inférieure ou empeigne ne réclame pas le même serrage que la partie montante.The problem encountered in tightening shoes with rising stem comes from the fact that the lower part or vamp does not require the same tightening as the rising part.

En effet, la partie inférieure comprend généralement des moyens de renvoi de forme "fermée" tels que boucles, passants, oeillets, etc qui forment un circuit permanent quelle que soit la tension de serrage par opposition aux moyens de renvoi de forme "ouverte" de la partie montante tels que crochets ou autres qui forment un circuit libérable dès que la tension de serrage est relâchée suffisamment.Indeed, the lower part generally includes return means of "closed" form such as loops, loops, eyelets, etc. which form a permanent circuit whatever the tightening tension as opposed to the return means of "open" shape of the rising part such as hooks or others which form a releasable circuit as soon as the voltage of tightening is released enough.

Dans un circuit du type permanent, les frottements sur le lacet sont importants au niveau des moyens de renvoi ; ce qui atténue la tension de serrage en direction du bout de la chaussure. Le résultat conduit à un serrage qui n'est pas homogène lorsque l'on tire sur les extrémités du lacet une première fois. Il faut ensuite reprendre le serrage en tirant en aval des parties de lacet insuffisamment serrées. Il faut donc dans cette partie améliorer le rendement avec un minimum de frottement pour obtenir un serrage correct sans reprise de serrage nécessaire.In a permanent type circuit, the friction on the lace are important in terms of return means; what attenuates the tightening tension towards the end of the shoe. The result leads to a tightening which is not homogeneous when you pull on the ends of the lace a first time. Then tighten again by pulling in downstream of the loosely tightened parts of the lace. Must therefore in this part improve the yield with a minimum of friction to obtain a correct tightening without resumption of tightening required.

Pour cela, on utilise en général des lacets de faible section et peu extensibles pour améliorer le glissement, limiter les frottements et ainsi favoriser le serrage. Mais pour un serrage efficace, il faut appliquer une tension suffisante sur les brins libres du lacet. Or, les faibles sections ont tendance à provoquer un effet de cisaillement dans les mains qui empêche d'appliquer des tensions suffisantes pour serrer efficacement la partie antérieure de tige. For this, we generally use small section laces and not very stretchy to improve sliding, limit friction and thus promote tightening. But for a tightening effective, apply sufficient tension to the strands free of the lace. However, small sections tend to cause a shearing effect in the hands which prevents apply sufficient tension to effectively tighten the anterior part of stem.

En plus, en raison de l'inextensibilité relative du lacet et de sa faible section, il est difficile d'obtenir un serrage progressif de la partie haute de tige. On a donc du mal à doser le serrage et celui-ci est souvent soit trop tendu donc provoquant un inconfort, soit trop lâche ; et dans ce cas il y a un risque que le lacet quitte les crochets lors d'une flexion notamment.In addition, due to the relative non-extensibility of the lace and of its small section, it is difficult to obtain a tightening progressive of the upper part of the rod. So it's hard to dose the tightening and it is often either too tight so causing discomfort, either too loose; and in this case there is at risk of the lace leaving the hooks during a bending in particular.

Le constat est donc qu'il n'existe pas aujourd'hui de lacet adapté aux chaussures de sport qui permette de serrer avec efficacité et homogénéité la partie de tige inférieure d'un seul geste tout en apportant une bonne préhension. Il n'existe pas plus de lacet qui confère tout à la fois un serrage efficace de la partie antérieure de la tige et une progressivité du serrage de la partie de tige montante.The observation is therefore that there is no lace today suitable for sports shoes which allows tightening with efficiency and consistency the lower stem part of a single gesture while providing a good grip. There is no no more lace which gives a tightening all at the same time effective of the anterior part of the stem and a progressive tightening of the rising stem part.

Il est connu d'utiliser des moyens de blocage d'un lacet au niveau d'une partie intermédiaire du circuit.It is known to use means for locking a lace at the level of an intermediate part of the circuit.

Par exemple, selon le document WO 85/00959, la tige montante dune chaussure est serrée par un lacet qui parcourt une partie basse et une partie haute de la tige. Les moyens de blocage réversible sont situés entre l'empeigne et le cou-de-pied, c'est-à-dire très loin du sommet de la partie haute où le lacet est noué.For example, according to document WO 85/00959, the rising stem a shoe is tightened by a lace which runs through a lower part and upper part of the rod. The means of reversible locks are located between the vamp and the instep, that is to say very far from the top of the upper part where the lace is tied.

Ainsi, il est possible de serrer la tige d'une certaine façon au niveau de l'empeigne, et d'une autre façon sur le reste du circuit.Thus, it is possible to tighten the rod of a certain one way at the level of the vamp, and another way on the rest of the circuit.

Il est également connu de réaliser un lacet comprenant des portions de nature différente. Par exemple, le document US 5,074,013 concerne un lacet de chaussure résistant à la traction, réalisé en tissu, comprenant deux extrémités de brins libres recouvertes de bandes en matériau auto-agrippant du type "Velcro". Le but de cette invention est tout à fait particulier. Il s'agit de procurer, après serrage, un lien résistant au glissement et ainsi d'empêcher le déliement du lacet.It is also known to make a lace comprising portions of a different nature. For example, the document US 5,074,013 relates to a shoe lace resistant to traction, made of fabric, comprising two ends of free strands covered with strips of self-gripping material "Velcro" type. The purpose of this invention is entirely particular. This is to provide, after tightening, a link resistant to slipping and thus prevent the untying of the lace.

Le but de la présente invention est donc de remédier aux inconvénients provenant du laçage des chaussures de sport.The object of the present invention is therefore to remedy the disadvantages from lacing sports shoes.

Plus précisément, l'un des buts de l'invention est d'apporter une solution satisfaisante en permettant un serrage différencié en fonction des besoins sur une chaussure de sport ; en particulier à tige montante. Un autre but est de rendre le serrage plus rapide et en évitant les problèmes de cisaillement.More specifically, one of the objects of the invention is provide a satisfactory solution by allowing a tightening differentiated according to the needs on a shoe sport ; in particular with a rising stem. Another goal is to make tightening faster and avoiding problems of shear.

Ces objets sont atteints par le choix d'un lacet qui comprend une portion centrale et deux portions d'extrémité se rattachant à la portion centrale ; la portion centrale ayant une section inférieure à la section des deux portions d'extrémité. Le lacet est réalisé en une seule pièce d'une tresse continue de fils. De préférence, ladite portion centrale est tressée plus serrée que les portions d'extrémité tressées plus lâches.These objects are achieved by choosing a lace which includes a central portion and two end portions connecting to the central portion; the central portion having a section smaller than the section of the two portions end. The lace is made in a single piece of continuous braid of threads. Preferably, said portion center is braided tighter than the end portions braided more loosely.

Une faible section du lacet de la portion centrale favorise le rendement de serrage en diminuant les frottements alors qu'une section plus importante des portions d'extrémités réduit le cisaillement et améliore la préhension lors du serrage et procure un serrage plus progressif à cet endroit. Ainsi, on obtient un lacet qui répond parfaitement aux besoins. La portion plus serrée présente un plus faible allongement et une moindre souplesse que les autres portions ; ce qui lui confère plus de rendement au serrage. Au contraire, l'extensibilité et la souplesse des portions d'extrémité favorisent la préhension, améliorent la progressivité du serrage et diminuent le risque de desserrage.A small section of the lace in the central portion favors the clamping performance by reducing friction while a larger section of the end portions reduces the shear and improves grip when tightening and provides more progressive tightening here. So, we obtains a lace that perfectly meets the needs. The part tighter has lower elongation and less flexibility than other portions; which gives it more tightening performance. On the contrary, the extensibility and the flexibility of the end portions favor gripping, improve tightening progressiveness and reduce the risk of loosening.

En plus, un lacet d'une seule pièce peut être fabriqué en continu par des moyens à tresser traditionnels de façon économique sans occasionner de problèmes de résistance ou autres. Bien entendu, l'invention concerne aussi la chaussure de sport munie d'un tel lacet.In addition, a one-piece lace can be made in continuous by traditional braiding means so economical without causing resistance problems or other. Of course, the invention also relates to the shoe of sport with such a lace.

Mais l'invention sera mieux comprise et d'autres caractéristiques encore seront mises en évidence à l'aide de la description qui suit en référence aux dessins schématiques annexés qui illustrent un mode de réalisation préféré, et dans lesquels :

  • la figure 1 est une vue en perspective de 3/4 avant d'une chaussure de sport selon l'invention au moment du serrage de la partie inférieure de tige ;
  • la figure 2 est une vue similaire à celle de la figure 1 une fois le serrage de la chaussure complètement réalisé ;
  • la figure 3 montre une vue générale d'un lacet de l'invention ;
  • la figure 3a est une vue en section selon A-A de la vue de la figure 3 ;
  • la figure 3b est une vue en section selon B-B de la vue de la figure 3 ;
  • la figure 3c est une vue en section selon C-C de la vue de la figure 3.
However, the invention will be better understood and other characteristics will be highlighted with the aid of the description which follows with reference to the appended schematic drawings which illustrate a preferred embodiment, and in which:
  • Figure 1 is a front 3/4 perspective view of a sports shoe according to the invention when tightening the lower part of the upper;
  • Figure 2 is a view similar to that of Figure 1 once the tightening of the shoe completely achieved;
  • Figure 3 shows a general view of a lace of the invention;
  • Figure 3a is a sectional view along AA of the view of Figure 3;
  • Figure 3b is a sectional view along BB of the view of Figure 3;
  • FIG. 3c is a view in section along CC of the view in FIG. 3.

En se reportant à la figure 1 ; il s'agit d'une chaussure ou botte 1 destinée à la pratique du surf des neiges. Une telle chaussure doit avoir une certaine souplesse favorisant la marche. Elle est destinée à être reliée à une planche de glisse par un dispositif de fixation comprenant des sangles de tension réglable (non représentées).Referring to Figure 1; it is a shoe or boot 1 intended for snowboarding. Such a shoe must have a certain flexibility favoring the market. It is intended to be connected to a gliding board by a fixing device comprising tension straps adjustable (not shown).

La chaussure comprend une semelle externe de marche 10, une tige souple 11 rattachée à la semelle.The shoe includes a walking outsole 10, a flexible rod 11 attached to the sole.

La tige 11 comprend une partie antérieure ou empeigne 110 et une partie de tige montante 111 prolongeant la partie antérieure 110 vers le haut pour recouvrir le bas de jambeThe rod 11 comprises an anterior part or vamp 110 and a part of rising stem 111 extending the front part 110 up to cover the lower leg

La tige 11 présente une ouverture 112 pour le passage du pied délimitée par deux quartiers latéraux antérieurs 110a, 110b de la partie antérieure et deux quartiers latéraux supérieurs 111a, 111b de la partie de tige montante. Les quartiers antérieurs sont bien entendu reliés aux quartiers supérieurs et la limite entre les uns et les autres ne peut pas toujours être déterminée de façon précise selon le type de construction de la chaussure.The rod 11 has an opening 112 for the passage of the foot bounded by two anterior lateral quarters 110a, 110b of the front part and two upper lateral quarters 111a, 111b of the rising stem part. The forequarters are of course connected to the upper districts and the limit between each other cannot always be determined precisely according to the type of construction of the shoe.

Une languette 114 est fixée à l'extrémité avant de la chaussure et recouvre partiellement l'ouverture entre les quartiers antérieurs et se prolonge entre les quartiers supérieurs.A tongue 114 is fixed to the front end of the shoe and partially covers the opening between the forequarters and extends between the quarters higher.

La tige 11 dispose d'un dispositif de serrage qui comprend une première série de moyens de renvoi 20 répartis de façon opposée sur chaque quartier latéral antérieur 110a, 110b dans la partie antérieure de la tige et une seconde série de moyens de renvoi 21 répartis de façon opposée sur chaque quartier latéral supérieur dans la partie de tige montante pour le serrage de la tige et la fermeture partielle de l'ouverture 112.The rod 11 has a clamping device which includes a first series of return means 20 distributed in opposite manner on each anterior lateral quarter 110a, 110b in the part anterior of the rod and a second series of return means 21 distributed in opposite directions on each lateral quarter upper in the rising stem part for tightening the rod and partial closure of the opening 112.

Dans l'exemple présenté, les moyens de renvoi de la première série 20 sont constitués de boucles fermées 20a, 20b, 20c, 20d, 20e, 20f, 20g, 20h se présentant sous la forme de sangles repliées et dont les extrémités sont reliées à la tige. Un tel mode présente l'avantage d'une construction avec surépaisseur minimale et est donc adaptée pour être insérée dans une fixation par sangles de surf des neiges sans création de surpressions ou point durs localisés au niveau des boucles. Les extrémités de rattachement des boucles sont, par exemple, cousues sur les bords de chaque quartier 110a, 110b de façon à ce que la partie en boucle proprement dite déborde de chaque quartier pour éviter une surépaisseur.In the example presented, the means of returning the first series 20 consist of closed loops 20a, 20b, 20c, 20d, 20th, 20f, 20g, 20h in the form of straps folded and whose ends are connected to the rod. Such mode has the advantage of a construction with extra thickness minimal and is therefore suitable for insertion into a binding by snowboard straps without creating overpressures or hard spots located at the loops. The ends of attachment loops are, for example, sewn on edges of each quarter 110a, 110b so that the portion in a proper loop overflows from each district to avoid an extra thickness.

Bien entendu, les moyens de renvoi préférés pourraient être remplacés par d'autres types de boucles fermées en métal, des oeillets, etc.Of course, the preferred return means could be replaced by other types of closed metal buckles, eyelets, etc.

Les moyens de renvoi de la seconde série sont, de préférence, des crochets ouverts 21a, 21b, 21c, 21d, 21e, 21f reliés à la tige ; et plus précisément aux quartiers supérieurs 111a, 111b.The return means of the second series are preferably open hooks 21a, 21b, 21c, 21d, 21e, 21f connected to the stem; and more precisely to the upper quarters 111a, 111b.

Entre les moyens de renvoi situés dans la partie antérieure 110 et ceux de la partie montante 111, il peut y avoir d'autres moyens de renvoi localisés à la frontière tels que ceux 30a, 30b représentés. Dans cet exemple, chaque moyen 30a, 30b est relié à une bande 113 cousue sur le reste de la structure de tige dont le serrage améliore la tenue de pied (?).Between the return means located in the front part 110 and those of the rising part 111, there may be other means of removal located at the border such as those 30a, 30b represented. In this example, each means 30a, 30b is connected to a band 113 sewn onto the rest of the rod structure, tightening improves foot support (?).

Pour compléter le dispositif de serrage, un lacet 4 selon l'invention est prévu pour le serrage de la tige 11.To complete the tightening device, a lace 4 according to the invention is intended for tightening the rod 11.

Le lacet s'étend de la partie antérieure 110 jusqu'en haut de la partie de tige montante 111.The lace extends from the front part 110 to the top of the rising stem part 111.

Le lacet 4 comprend une première portion ou portion centrale 40 coopérant avec la première série de moyens de renvoi 20 agissant en serrage sur lesdits quartiers antérieurs 110a, 110b et deux secondes portions ou portions d'extrémité 41, 42 coopérant avec la seconde série de moyens de renvoi 21 agissant en serrage sur lesdits quartiers supérieurs 111a, 111b et se terminant par deux bouts de brins libres. Selon une caractéristique importante de l'invention, la portion centrale 40 présente une section inférieure à la section des deux portions d'extrémité 41, 42.The lace 4 includes a first portion or central portion 40 cooperating with the first series of return means 20 acting in clamping on said front quarters 110a, 110b and two second portions or end portions 41, 42 cooperating with the second series of return means 21 acting clamped on said upper quarters 111a, 111b and ending with two ends of free strands. According to one important characteristic of the invention, the central portion 40 has a section smaller than the section of the two end portions 41, 42.

La figure 1 montre l'opération de serrage de la partie antérieure 110 de la chaussure. La section plus importante des portions 41, 42 favorise une bonne préhension du lacet au moment d'exécuter un effort de traction des deux brins libres du lacet ; tandis que la section plus faible de la portion centrale 40 confère un meilleur rendement de serrage en diminuant les frottements dans les boucles fermées de la série des moyens de renvoi 20.Figure 1 shows the tightening operation of the part anterior 110 of the shoe. The larger section of portions 41, 42 promotes good grip of the lace at the time to execute a traction effort of the two free strands of the lace ; while the lower section of the central portion 40 provides better clamping performance by reducing the friction in closed loops of the series of means reference 20.

En condition normale de desserrage de la partie antérieure de tige, il est préférable que la longueur de la portion centrale du lacet 4 soit au moins égale au circuit de liaison de la première série des moyens de renvoi 20.In normal condition of loosening of the anterior part of stem, it is better that the length of the central portion of yaw 4 is at least equal to the link circuit of the first series of return means 20.

Par contre, dans les moyens de renvoi 30a, 30b peuvent s'engager le début des portions d'extrémité 41, 42 pour obtenir un certain frottement en aval de la série des moyens 20 ; propice à maintenir un serrage de la partie de tige antérieure. Avantageusement, les moyens de renvoi 30a, 30b peuvent être remplacés par des moyens de blocage de lacet aptes à conserver la tension de serrage de la partie antérieure avant d'effectuer le laçage et serrage de la partie de tige montante.On the other hand, in the return means 30a, 30b can engage the beginning of the end portions 41, 42 to obtain some friction downstream of the series of means 20; conducive to maintaining a tightening of the front rod part. Advantageously, the return means 30a, 30b can be replaced by yaw locking means capable of retaining the tightening tension of the front part before carrying out lacing and tightening of the rising rod part.

La figure 2 montre la chaussure 1 lorsque le laçage est entièrement réalisé. Grâce au lacet de l'invention qui offre des portions de surface de contact variables avec les moyens de renvoi, il est possible d'obtenir un serrage relativement différencié entre la partie antérieure 110 et la partie montante 111 de la tige. Le serrage est ainsi plus homogène dans chaque partie et plus adapté aux besoins en matière de tenue de pied, sensations, confort, etc.Figure 2 shows shoe 1 when the lacing is fully realized. Thanks to the lace of the invention which offers variable contact area with the means of reference, it is possible to obtain a relatively tightening differentiated between the front part 110 and the rising part 111 of the stem. The tightening is thus more homogeneous in each part and more adapted to the needs in terms of foot holding, sensations, comfort, etc.

Les figures 3, 3a, 3b, 3c montrent un exemple d'un lacet selon l'invention.Figures 3, 3a, 3b, 3c show an example of a lace according to the invention.

La portion centrale 40 possède une section plus faible que la section des extrémités 40, 41. Par section, il faut entendre la surface représentée par la coupe du lacet dans un état sans tension.The central portion 40 has a smaller section than the section of the ends 40, 41. By section, we mean the surface represented by the lace cut in a state without voltage.

De préférence, la portion 40 présente un pourtour sensiblement circulaire pour favoriser le glissement quel que soit le vrillage de la portion du lacet.Preferably, the portion 40 has a periphery substantially circular to promote sliding whatever the twist of the lace portion.

Les portions d'extrémité 41, 42 peuvent présenter quant à elles un pourtour circulaire ou non circulaire.The end portions 41, 42 may have as to they have a circular or non-circular periphery.

Avantageusement, le lacet est réalisé en une seule pièce d'une tresse de fils. La portion centrale sera tressée plus serrée que les portions d'extrémité tressées plus lâches. Autrement dit, la densité de fil est plus importante dans la portion 40 que dans les autres portions. Cette portion est par conséquent plus raide et présente un allongement inférieur ; ce qui améliore son rendement au serrage dans un circuit du type à boucles "fermées". Advantageously, the lace is made in a single piece of braid of son. The central portion will be braided tighter than the looser braided end portions. In other words, the wire density is higher in portion 40 than in the other portions. This portion is therefore steeper and has a lower elongation; which improves his tightening efficiency in a loop type circuit "Closed".

Le tressage s'obtient en continu par des techniques traditionnelles de tressage au moyen de métiers à tresser du type circulaire et dont les paramètres sont modifiés au cours du tressage pour obtenir les différentes portions caractéristiques.Braiding is obtained continuously by techniques traditional braiding by means of braiding looms circular type and whose parameters are modified during the braiding to obtain the different characteristic portions.

Le lacet peut être réalisé dans des fils souples de différente nature telle qu'en matériau naturel ou synthétique. Il peut être renforcé par une âme métallique ou comprendre des fils métalliques mélangés aux fils souples. Bien entendu, la présente invention n'est pas limitée aux modes de réalisation décrits et inclut tout mode équivalent rentrant dans le cadre des revendications ci-après.The lace can be made in flexible threads of different nature such as in natural or synthetic material. He can be reinforced by a metallic core or include wires of metal mixed with flexible wires. Of course, this invention is not limited to the embodiments described and includes any equivalent mode falling within the scope of claims below.
