En effet, un bon maintien du pied dans la tige permet une meilleure utilisation.A shoe may include a low or high shaft. The shoe can also be relatively flexible or on the contrary more rigid. However it is in all cases desirable that the foot of a user is sufficiently maintained. Indeed, a good support of the foot in the stem allows a better use.

Par exemple avec une chaussure souple à tige basse, telle qu'utilisée pour courir en montagne, un maintien suffisant facilite le déroulement du pied ou la transmission d'informations sensorielles. Notamment au niveau de l'empeigne, un dispositif de serrage de la tige est destiné à maintenir au moins le cou-de-pied d'un utilisateur.For example with a soft shoe with low shank, as used for running in the mountains, sufficient support facilitates the unfolding of the foot or the transmission of sensory information. In particular at the upper, a device for clamping the rod is intended to maintain at least the instep of a user.

Traditionnellement un dispositif de serrage comprend, d'une part, un lacet et, d'autre part, des points de liaison du lacet à la tige. Ces points de liaison sont matérialisés par des passants, associés à des quartiers latéral et médial de la tige. Le lacet suit un chemin qui le mène alternativement d'un quartier à l'autre. Ainsi il suffit de tirer sur le lacet pour rapprocher les quartiers et serrer la tige. Ensuite, le blocage du lacet maintient le serrage. Un premier problème devant être résolu par un bon dispositif de serrage est l'adaptation aux différentes morphologies du pied et un confort, c'est-à-dire un maintien sans surpression. Un autre problème est le maintien du confort de serrage pendant l'utilisation.Traditionally a clamping device comprises, on the one hand, a lace and, on the other hand, binding points of the lace to the rod. These points of connection are materialized by passers-by, associated with lateral and medial quarters of the stem. The lace follows a path that leads alternately from one neighborhood to another. Thus just pull on the lace to bring neighborhoods and tighten the rod. Then, the locking of the lace maintains the tightening. A first problem to be solved by a good clamping device is the adaptation to the different morphologies of the foot and comfort, that is to say a maintenance without overpressure. Another problem is maintaining the comfort of clamping during use.

En effet, en position statique la traction sur le lacet tend ce dernier de manière importante au niveau du cou-de-pied ou du pli de flexion. Mais la tension est moindre vers les orteils. C'est pourquoi le serrage est généralement plus important vers le cou-de-pied ou le pli de flexion que vers les orteils. Ensuite, pendant la marche ou l'utilisation sportive, les déformations de la tige permettent un certain équilibrage des tensions sur la longueur du lacet. Il s'ensuit que le serrage devient mieux réparti. Cependant il est apparu que le maintien du pied n'est pas toujours de bonne qualité, dans le sens où il n'est pas suffisamment uniforme.Indeed, in the static position traction on the lace tends the latter significantly in the instep or bending fold. But the tension is less towards the toes. This is why the tightening is generally greater towards the instep or the bending fold than towards the toes. Then, during the walk or sporty use, the deformations of the stem allow a certain balancing of the tensions on the length of the lace. It follows that the tightening becomes better distributed. However it has become apparent that the maintenance of the foot is not always of good quality, in the sense that it is not sufficiently uniform.

Certaines portions du pied sont trop serrées alors que d'autres ne le sont pas assez. Ou bien une portion donnée du pied est tantôt trop serrée et tantôt pas assez.Some portions of the foot are too tight while others are not enough. Or a given portion of the foot is sometimes too tight and sometimes not enough.

En fait, au cours d'un cycle de marche, le pied change de forme rapidement. Des portions se courbent et se redressent alternativement. Des sections du pied peuvent s'élargir puis se rétrécir, ou s'épaissir puis s'amincir. Le cycle de marche est si rapide que les tensions du lacet n'ont pas le temps de s'équilibrer complètement. C'est pourquoi il subsiste des disparités dans la répartition de serrage de la tige. En conséquence le maintien du pied n'est généralement pas parfait lors de l'utilisation, les disparités de serrage de la tige se répercutant sur le pied.In fact, during a walking cycle, the foot changes shape quickly. Portions bend and straighten alternately. Sections of the foot may widen, then narrow, or thicken and then thin. The walking cycle is so fast that the yaw tensions do not have time to fully balance. This is why there are still disparities in the clamping distribution of the rod. Consequently the maintenance of the foot is generally not perfect during use, the disparities of tightening of the stem affecting the foot.

L'invention a notamment pour but d'améliorer le maintien du pied d'un utilisateur dans une chaussure. Plus particulièrement, l'invention cherche à améliorer les répartitions des tensions dans un dispositif de serrage à lacet. L'invention vise à améliorer le comportement en utilisation statique et/ou dynamique.The invention particularly aims to improve the maintenance of the foot of a user in a shoe. More particularly, the invention seeks to improve the distribution of the tensions in a lace tightening device. The invention aims to improve the behavior in static and / or dynamic use.

Pour ce faire l'invention propose une chaussure comprenant une semelle et une tige, la tige comprenant un quartier latéral, un quartier médial, et un dispositif de serrage de la tige, le dispositif de serrage comprenant un premier brin de lacet latéral et au moins deux points de liaison du premier brin latéral au quartier latéral, ainsi qu'un premier brin de lacet médial et au moins deux points de liaison du premier brin médial au quartier médial.To do this, the invention provides a shoe comprising a sole and a rod, the upper comprising a lateral quarter, a medial quarter, and a device for clamping the upper, the clamping device comprising a first side lace strand and at least one two connecting points of the first lateral strand to the lateral quarter, and a first strand of medial lace and at least two points of connection of the first medial strand to the medial quarter.

La chaussure selon l'invention est caractérisée par le fait que chaque brin latéral ou médial comprend respectivement une portion intermédiaire latérale ou une portion intermédiaire médiale qui s'étend entre deux points de liaison d'un même quartier latéral ou médial, sans passer par un point de liaison de l'autre quartier latéral ou médial, et par le fait qu'elle comprend un moyen de connexion reliant les portions intermédiaires latérales et médiales des brins respectivement latéral et médial, le moyen de connexion permettant un glissement d'au moins l'un des brins latéral et médial.The shoe according to the invention is characterized in that each lateral or medial strand comprises respectively a lateral intermediate portion or a medial intermediate portion which extends between two connection points of the same lateral or medial quarter, without passing through a connecting point of the other side or medial quarter, and in that it comprises a connecting means connecting the intermediate and medial intermediate portions of the strands respectively lateral and medial, the connecting means allowing a sliding of at least l one of the lateral and medial strands.

Au lieu de passer alternativement d'un quartier à l'autre, comme c'est le cas pour l'art antérieur, un brin de lacet passe alternativement d'un point de liaison à un moyen de connexion entre deux brins. Ainsi la longueur du brin qui frotte sur la tige est réduite. De plus le moyen de connexion, parce qu'il permet le glissement de l'un au moins des brins, se déplace légèrement par rapport au brin pendant le cycle de marche. Bien entendu, le moyen de connexion se déplace aussi par rapport à la tige. En conséquence les tensions s'équilibrent entre les brins et au sein des brins. Le moyen de connexion prend naturellement une place pour laquelle les tensions des brins sont équilibrées. Bien entendu cette place est mobile pendant le cycle de marche. Le glissement du moyen de connexion permet également une meilleure adaptation aux différentes morphologies du pied.Instead of passing alternately from one quarter to another, as is the case for the prior art, a lace strand alternately passes from a connection point to a connecting means between two strands. Thus the length of the strand that rubs on the rod is reduced. In addition, the connection means, because it allows the sliding of at least one of the strands, moves slightly with respect to the strand during the walking cycle. Of course, the connection means also moves relative to the rod. As a result the tensions are balanced between the strands and within the strands. The connection means naturally takes place for which the tensions of the strands are balanced. Of course, this place is mobile during the walking cycle. The sliding connection means also allows better adaptation to the different morphologies of the foot.

Un avantage qui en découle est que le serrage de la tige, et donc aussi du pied, est plus homogène. L'homogénéité est conservée, à la fois en statique, par exemple si l'utilisateur se tient debout, et en dynamique, c'est-à-dire pendant la marche ou la course. Ainsi la répartition des tensions dans le dispositif de serrage à lacet est améliorée.An advantage that arises is that the clamping of the rod, and thus the foot, is more homogeneous. The homogeneity is preserved, both statically, for example if the user is standing, and dynamic, that is to say during walking or running. Thus the distribution of the tensions in the yaw clamp is improved.

La première forme de réalisation qui va être décrite après concerne plus spécialement des chaussures pour la marche ou la course à plat ou en terrain mouvementé. Cependant l'invention s'applique à d'autres domaines tels que ceux évoqués avant.The first embodiment that will be described after more specifically relates to shoes for walking or running flat or on rough ground. However, the invention applies to other fields such as those mentioned before.

La première forme est décrite ci-après à l'aide des figures 1 à 3.The first form is described below with reference to FIGS. 1 to 3.

Comme le montre la figure 1, une chaussure de course est prévue pour accueillir le pied de l'utilisateur.As shown in Figure 1, a running shoe is provided to accommodate the user's foot.

De manière connue, la chaussure 1 comprend une semelle de marche 2 et une tige 3. La chaussure 1 s'étend en longueur entre une extrémité arrière ou talon 4 et une extrémité avant ou pointe 5, et en largeur entre un côté latéral 6 et un côté médial 7.In known manner, the shoe 1 comprises a tread 2 and a shank 3. The shoe 1 extends in length between a rear end or heel 4 and a front end or tip 5, and in width between a lateral side 6 and a medial side 7.

Telle que représentée, la tige 3 comprend une portion basse 10 prévue pour entourer le pied, à l'exception d'une portion haute. Cependant, il pourrait être également prévu que la tige comprenne aussi une portion haute.As shown, the rod 3 comprises a lower portion 10 provided to surround the foot, with the exception of a high portion. However, it could also be expected that the stem also comprises an upper portion.

La chaussure 1 est structurée pour permettre un bon déroulement du pied pendant la marche, des transmissions d'informations sensorielles, et des impulsions pour des appuis ou des réceptions. C'est pourquoi la semelle 2 et la tige 3 sont relativement souples.The shoe 1 is structured to allow a smooth running of the foot during walking, transmissions of sensory information, and impulses for support or receptions. This is why the sole 2 and the rod 3 are relatively flexible.

Cependant, il pourrait être également prévu que la chaussure soit plus rigide pour faciliter certaines pratiques, comme l'escalade ou le cyclisme.However, it could also be expected that the shoe is more rigid to facilitate certain practices, such as climbing or cycling.

La tige 3 comprend un dessus 11, lequel présente notamment un quartier latéral 12, un quartier médial 13, et une languette 14. Cette dernière 14 relie l'un à l'autre les quartiers 12, 13 pour donner au dessus 11 sa continuité. Cependant, il pourrait être prévu de ne pas utiliser de languette. Dans ce cas, les quartiers 12, 13 peuvent rester séparés ou se superposer.The upper 3 comprises a top 11, which has in particular a lateral quarter 12, a medial quarter 13, and a tongue 14. The latter 14 connects the quarters 12, 13 to one another to give the top 11 its continuity. However, it could be planned not to use a tab. In this case, the neighborhoods 12, 13 may remain separate or superimposed.

Le dessus 11 est solidarisé par sa base 15 à la semelle 2, au niveau de la périphérie de la semelle. La solidarisation est faite par collage. Cependant un autre moyen tel qu'une couture, ou la combinaison d'un collage et d'une couture, pourrait convenir.The top 11 is secured by its base 15 to the sole 2, at the periphery of the sole. The joining is done by gluing. However, other means such as sewing, or the combination of a collage and a seam, could be suitable.

En référence aux figures 1 et 2, un premier dispositif de serrage 20 est prévu pour serrer le dessus 11 de manière réversible.Referring to Figures 1 and 2, a first clamping device 20 is provided for clamping the top 11 reversibly.

Le premier dispositif de serrage 20 comprend un premier brin de lacet latéral 21 et au moins deux points de liaison 22, 23, 24, 25, 26 du premier brin latéral 21 au quartier latéral 12. Plus précisément, selon la première forme de réalisation de l'invention, il est prévu des premier 22, deuxième 23, troisième 24, quatrième 25 et cinquième 26 points de liaison.The first clamping device 20 comprises a first lateral lace strand 21 and at least two connection points 22, 23, 24, 25, 26 of the first lateral strand 21 to the lateral quarter 12. More specifically, according to the first embodiment of the invention, there are provided first 22, second 23, third 24, fourth 25 and fifth 26 connection points.

Bien entendu, un nombre de points différent de cinq peut être prévu.Of course, a number of points other than five may be provided.

Par analogie, le premier dispositif de serrage 20 comprend aussi un premier brin de lacet médial 31 et au moins deux points de liaison 32, 33, 34 du premier brin médial 31 au quartier médial 13. Plus précisément, il est prévu des premier 32, deuxième 33 et troisième 34 points de liaison.By analogy, the first clamping device 20 also comprises a first medial shunt strand 31 and at least two connection points 32, 33, 34 of the first medial strand 31 to the medial area 13. More specifically, first 32 is provided, second 33 and third 34 points of connection.

Bien entendu, là encore, un nombre différent de trois peut être prévu.Of course, again, a different number of three can be expected.

Selon l'invention, chaque brin latéral 21 ou médial 31 comprend respectivement une portion intermédiaire latérale 40, 41, 42, 43 ou une portion intermédiaire médiale 44, 45 qui s'étend entre deux points de liaison d'un même quartier latéral 12 ou médial 13, sans passer par un point de liaison de l'autre quartier latéral ou médial, et un moyen de connexion mobile 46, 47, 48, 49 relie les portions intermédiaires latérales 40, 41, 42, 43 et médiales 44, 45 des brins 21, 31 respectivement latéral et médial, le moyen de connexion mobile 46, 47, 48, 49 permettant un glissement d'au moins l'un des brins latéral 21 et médial 31. Le moyen de connexion mobile est constitué par exemple par un passant non attaché qui sera décrit plus loin.According to the invention, each lateral or medial strand 31 comprises respectively a lateral intermediate portion 40, 41, 42, 43 or a medial intermediate portion 44, 45 which extends between two connection points of the same lateral quarter 12 or medial 13, without passing through a connecting point of the other lateral or medial quarter, and a movable connection means 46, 47, 48, 49 connects the lateral intermediate portions 40, 41, 42, 43 and medial 44, 45 of the strands 21, 31 respectively lateral and medial, the mobile connection means 46, 47, 48, 49 allowing a sliding of at least one of the lateral strands 21 and medial 31. The mobile connection means is constituted for example by a unassigned passer which will be described later.

Ainsi un brin de lacet passe alternativement d'un point de liaison à un moyen de connexion mobile en glissant entre deux brins. Le glissement du moyen de connexion favorise l'équilibrage des tensions entre les brins et au sein des brins.Thus a lace strand alternately passes from a connection point to a mobile connection means by sliding between two strands. The sliding of the connecting means promotes the balancing of the tensions between the strands and within the strands.

Selon la première forme de réalisation de l'invention, au niveau du premier brin de lacet latéral 21, les premier 22 et cinquième 26 points de liaison sont respectivement des points d'attache. Cela signifie qu'aux points 22 et 26 le brin de lacet 21 est solidarisé à la tige 3 sans se déplacer. Le moyen de solidarisation est réalisé par exemple par couture, par collage, par nouage, à l'aide d'un bloqueur, ou par tout autre moyen.According to the first embodiment of the invention, at the first lateral lace strand 21, the first 22 and fifth 26 connection points are respectively attachment points. This means that at points 22 and 26 the yaw 21 is secured to the rod 3 without moving. The securing means is made for example by sewing, gluing, knotting, using a blocker, or by any other means.

Entre les points d'attache 22, 26, les deuxième 23, troisième 24 et quatrième 25 points de liaison sont respectivement des passants. Selon la forme de réalisation décrite, les passants 23, 24, 25 comprennent des boucles solidarisées à la tige 3, mais ils pourraient aussi se présenter sous d'autres formes, comme des orifices ménagés dans la tige 3, ou autre.Between the attachment points 22, 26, the second 23, third 24 and fourth 25 connection points are respectively passers. According to the embodiment described, the loops 23, 24, 25 comprise loops secured to the rod 3, but they could also be in other forms, such as orifices in the rod 3, or other.

Depuis le premier point de liaison 22 jusqu'au cinquième 26, et entre deux points de liaison successifs, le brin latéral 21 présente respectivement des première 40, deuxième 41, troisième 42, et quatrième 43 portions. Bien entendu, chaque portion 40, 41, 42, 43 est une subdivision du brin 21.From the first connection point 22 to the fifth 26, and between two successive connection points, the lateral strand 21 has respectively first 40, second 41, third 42, and fourth 43 portions. Of course, each portion 40, 41, 42, 43 is a subdivision of the strand 21.

Il est prévu que, en moyenne, une portion 40, 41, 42, 43 est un peu plus longue que la distance de séparation entre les points de liaison 22, 23, 24, 25, 26. Ainsi les portions 40, 41, 42, 43 sont des boucles réparties entre les attaches 22, 26. Etant donné que le brin de lacet 21 peut glisser dans les passants 23, 24, 25, les portions ou boucles 40, 41, 42, 43 peuvent respectivement s'agrandir ou se réduire. Bien entendu, l'agrandissement d'une ou plusieurs boucles engendre la réduction d'une ou plusieurs autres boucles. Les portions 40, 41, 42, 43 portent les moyens de connexion mobiles 46, 47, 48, 49 et font en fait office de passant à géométrie variable pour le brin de lacet médial 31.It is expected that, on average, a portion 40, 41, 42, 43 is a little longer than the separation distance between the connection points 22, 23, 24, 25, 26. Thus the portions 40, 41, 42 , 43 are loops distributed between the fasteners 22, 26. Since the lace strand 21 can slide in the loops 23, 24, 25, the portions or loops 40, 41, 42, 43 can respectively expand or reduce. Of course, the enlargement of one or more loops causes the reduction of one or more other loops. Portions 40, 41, 42, 43 carry the movable connection means 46, 47, 48, 49 and in fact act as a variable-geometry passer for the medial lace-strand 31.

Dans le même esprit, au niveau du premier brin de lacet médial 31, le premier point de liaison 32 est une attache et les deuxième 33 et troisième 34 points de liaison sont des passants. Le brin de lacet médial 31 s'étend non seulement entre l'attache 32 et les passants 33, 34, mais encore au-delà du passant 34 ou troisième point de liaison par une extrémité libre 55.In the same spirit, at the first medial yaw end 31, the first connection point 32 is a fastener and the second 33 and third 34 connecting points are passers-by. The medial lace strand 31 extends not only between the fastener 32 and the loops 33, 34, but also beyond the passer 34 or third point of connection by a free end 55.

Depuis le premier point de liaison 32 jusqu'au troisième 34, et entre deux points de liaison successifs, le brin médial 31 présente respectivement des première 44 et deuxième 45 portions
ou boucles. Là encore le brin 31 peut glisser dans les passants 33, 34 et les boucles 44, 45 peuvent s'agrandir ou se réduire afin de permettre le serrage de la tige, ainsi qu'on le verra mieux après. En effet l'extrémité libre 55 du premier brin 31 permet à l'utilisateur d'exercer un effort de traction dans le sens de la flèche F1 en vue du serrage. Bien entendu, cet effort F1 tend à réduire la longueur des boucles 44, 45.From the first connection point 32 to the third 34, and between two successive connection points, the medial strand 31 has first 44 and second 45 portions respectively.
or loops. Again the strand 31 can slide in the loops 33, 34 and loops 44, 45 can expand or reduce to allow the clamping of the rod, as will be seen later. Indeed the free end 55 of the first strand 31 allows the user to exert a tensile force in the direction of the arrow F1 for tightening. Of course, this effort F1 tends to reduce the length of the loops 44, 45.

Selon la première forme de réalisation de l'invention, le dispositif de serrage 20 de la chaussure 1 comprend encore un deuxième brin de lacet médial 61. Ce dernier est relié à la tige 3 par un premier 62 et un deuxième 63 points de liaison.According to the first embodiment of the invention, the clamping device 20 of the boot 1 further comprises a second medial lace strand 61. The latter is connected to the rod 3 by a first 62 and a second 63 connecting points.

Toujours dans le même esprit, le premier point de liaison 62 du deuxième brin 61 est une attache, et le deuxième point de liaison 63 est un passant. Le deuxième brin de lacet médial 61 s'étend entre l'attache 62 et le passant 63, et aussi au-delà du passant 63 ou deuxième point de liaison par une extrémité libre 64.Still in the same spirit, the first point of connection 62 of the second strand 61 is a fastener, and the second point of connection 63 is a passer. The second medial lace strand 61 extends between the fastener 62 and the passer 63, and also beyond the passer 63 or second connection point by a free end 64.

Entre le premier 62 et le deuxième 63 point de liaison, le deuxième brin médial 61 présente une première portion 65 ou boucle. Là encore le brin 61 peut glisser dans le passant 63, et la boucle 65 peut s'agrandir ou se réduire.Between the first 62 and second 63 binding point, the second medial strand 61 has a first portion 65 or loop. Again the strand 61 can slide in the loop 63, and the loop 65 can expand or shrink.

On le verra mieux après, l'extrémité libre 64 du deuxième brin 61 permet à l'utilisateur d'exercer un effort de traction dans le sens de la flèche F2. Bien entendu, cet effort F2 tend à réduire la longueur de la boucle 65 entre les points 62 et 63.It will be seen better later, the free end 64 of the second strand 61 allows the user to exert a tensile force in the direction of the arrow F2. Of course, this effort F2 tends to reduce the length of the loop 65 between points 62 and 63.

On remarque que les points de liaison respectifs du premier brin médial 31 et deuxième brin médial 61 sont disposés en alternance sur un quartier de la tige. On trouve successivement, dans le sens de la pointe 5 vers le talon 4, le premier point 32 du premier brin 31, le premier point 62 du deuxième brin 61, le deuxième point 33 du premier brin 31, le deuxième point 63 du deuxième brin 61, et enfin le troisième point 34 du premier brin 31. Les différents points 32, 62, 33, 63, 34 se suivent selon une courbe incurvée, comme on le voit sur la figure 1. Cette observation est également valable pour les points de liaison 22 à 26 du premier brin de lacet latéral 21. Les points 22 à 26 se suivent selon une courbe incurvée. La figure 2 donne une représentation schématique alignée pour des raisons de commodité. Cependant il peut effectivement être prévu une alternative de construction pour laquelle les points sont plus alignés.Note that the respective connection points of the first medial strand 31 and second medial strand 61 are arranged alternately on a quarter of the stem. We successively find, in the direction of the point 5 towards the heel 4, the first point 32 of the first strand 31, the first point 62 of the second strand 61, the second point 33 of the first strand 31, the second point 63 of the second strand. 61, and finally the third point 34 of the first strand 31. The various points 32, 62, 33, 63, 34 follow one another in a curved curve, as can be seen in FIG. 1. This observation is also valid for the points of link 22 to 26 of the first lateral lace strand 21. The points 22 to 26 follow one another in a curved curve. Figure 2 gives a schematic representation aligned for convenience. However it can actually be expected a construction alternative for which the points are more aligned.

La chaussure 1 selon la première forme de réalisation comprend encore des moyens de connexion 46, 47, 48, 49 qui relient respectivement une portion d'un brin latéral 21 à une portion d'un brin médial 31, 61. Plus précisément un premier moyen de connexion 46 relie la première boucle 40 du premier brin latéral 31 à la première boucle 44 du premier brin médial 31. Ensuite un deuxième moyen de connexion 47 relie la deuxième boucle 41 du premier brin latéral 31 à la première boucle 65 du deuxième brin de lacet médial 61. Puis un troisième moyen de connexion 48 relie la troisième boucle 42 du premier brin latéral 31 à la deuxième boucle 45 du premier brin médial 31. Enfin un quatrième moyen de connexion 49 relie la quatrième boucle 43 du premier brin latéral 31 à l'extrémité libre 64 du deuxième brin 61.The boot 1 according to the first embodiment further comprises connection means 46, 47, 48, 49 which respectively connect a portion of a lateral strand 21 to a portion of a medial strand 31, 61. Specifically a first connection means 46 connects the first loop 40 of the first lateral strand 31 to the first loop 44 of the first medial strand 31. Then a second connection means 47 connects the second loop 41 of the first lateral strand 31 to the first loop 65 of the second medial lace strand 61. Then a third connection means 48 connects the third loop 42 of the first lateral strand 31 to the second loop 45 of the first medial strand 31. Finally a fourth connection means 49 connects the fourth loop 43 of the first lateral strand 31 to the free end 64 of the second strand 61.

Les moyens de connexion 46 à 49 se succèdent dans une direction allant de la pointe 5 au talon 4. Ces moyens 46 à 49 connectent le premier brin de lacet latéral 21 alternativement au premier brin médial 31 et au deuxième brin médial 61.The connection means 46 to 49 follow each other in a direction from the tip 5 to the heel 4. These means 46 to 49 connect the first lateral lace strand 21 alternately to the first medial strand 31 and the second medial strand 61.

Chaque moyen de connexion 46, 47, 48, 49 permet un glissement des brins de lacet 21, 31, 61 qu'il relie. C'est pourquoi le dispositif de serrage de la chaussure 1 s'apparente à un filet dont chaque maille est à périmètre variable.Each connection means 46, 47, 48, 49 allows a sliding of the lace strands 21, 31, 61 it connects. This is why the clamping device of the shoe 1 is similar to a net with each mesh is variable perimeter.

Comme le montre la figure 3, chaque moyen de connexion 46, 47, 48, 49 comprend un corps 70 évidé pour laisser passer des brins de lacet. En l'occurrence, par exemple, le corps 70 du troisième moyen de connexion 48 est traversé par un premier 71 et un deuxième 72 orifices qui guident respectivement le premier brin de lacet médial 31 et le premier brin de lacet latéral 21. Chaque orifice 71, 72 est un tube qui traverse le corps 70. Chaque tube 71, 72 présente une section supérieure ou égale à celle du lacet. Les tubes sont sensiblement situés dans un même plan. Ils 71, 72 sont incurvés pour donner une régularité de parcours au brin de lacet. Cependant ils 71, 72 pourraient alternativement être plus droits. Le corps 70 comprend une matière plastique ou une matière métallique. Le corps 70 constitue en fait un passant mobile, c'est-à-dire non attaché à la tige.As shown in Figure 3, each connection means 46, 47, 48, 49 comprises a hollow body 70 for passing lace strands. In this case, for example, the body 70 of the third connecting means 48 is traversed by a first 71 and a second 72 orifices which respectively guide the first medial lace strand 31 and the first lateral lace strand 21. Each orifice 71 , 72 is a tube which passes through the body 70. Each tube 71, 72 has a section greater than or equal to that of the lace. The tubes are substantially located in the same plane. They 71, 72 are curved to give a regularity of course to the yaw. However they 71, 72 could alternatively be more straight. The body 70 comprises a plastics material or a metallic material. The body 70 is in fact a mobile loop, that is to say not attached to the rod.

Etant donné que les brins de lacet 21, 31, 61 glissent dans leurs passants respectifs 23, 24, 25, 33, 34, 63, et que les brins de lacet 21, 31, 61 glissent aussi dans les moyens de connexion 46, 47, 48, 49, les tensions dans les trois brins s'équilibrent facilement dans l'ensemble du dispositif de serrage 20. Si les attaches 22, 26, 32, 62 et les passants 23, 24, 25, 33, 34, 63 sont solidaires du quartier latéral 12 ou du quartier médial 13 de la tige 3, les moyens de connexion 46, 47, 48, 49 sont quant à eux mobiles par rapport à la tige 3 dans le sens où ils ne sont pas solidaires de la tige. Ils 46, 47, 48, 49 peuvent s'approcher ou s'éloigner d'un quartier 12, 13, ou bien bouger longitudinalement dans un sens de rapprochement ou d'éloignement de la pointe 5. Les moyens de connexion peuvent aussi bouger dans un sens de hauteur de la chaussure, en s'approchant ou en s'éloignant de la semelle. Chaque brin de lacet 21, 31, 64 passe en fait alternativement par des passants fixes 23, 24, 25, 33, 34, 63 solidaires de la tige et par des passants mobiles 46, 47, 48, 49 par rapport à la tige.Since the lace strands 21, 31, 61 slide in their respective loops 23, 24, 25, 33, 34, 63, and the lace strands 21, 31, 61 also slide in the connection means 46, 47 , 48, 49, the tensions in the three strands are easily balanced throughout the clamp 20. If the fasteners 22, 26, 32, 62 and the loops 23, 24, 25, 33, 34, 63 are secured to the lateral quarter 12 or the medial quarter 13 of the rod 3, the connection means 46, 47, 48, 49 are in turn movable relative to the rod 3 in the sense that they are not integral with the rod. They 46, 47, 48, 49 can approach or move away from a quarter 12, 13, or move longitudinally in a direction of approximation or removal of the tip 5. The connection means can also move in a sense of height of the shoe, approaching or moving away from the sole. Each lace strand 21, 31, 64 in fact passes alternately by fixed loops 23, 24, 25, 33, 34, 63 secured to the rod and by movable loops 46, 47, 48, 49 relative to the rod.

Du fait de cette mobilité, les moyens de connexion 46, 47, 48, 49 se placent naturellement dans une position d'équilibre des tensions entre les brins 21, 31, 61 et s'adaptent donc dans un premier temps à la morphologie du pied, selon un mode de serrage statique, puis dans un deuxième temps aux variations de formes du pied, selon un mode de serrage dynamique. Les placements varient pendant un cycle de marche. Les différentes boucles 40, 41, 42, 43, 44, 45, 65 s'agrandissent ou se réduisent alternativement pendant le cycle. Comme les tensions des brins sont équilibrées, aucune portion du pied maintenu n'est trop serrée ou trop relâchée.Due to this mobility, the connection means 46, 47, 48, 49 are naturally placed in a position of equilibrium of the tensions between the strands 21, 31, 61 and thus adapt initially to the morphology of the foot. , according to a static clamping mode, then in a second step to variations of foot shapes, according to a dynamic clamping mode. The placements vary during a walking cycle. The different loops 40, 41, 42, 43, 44, 45, 65 expand or decrease alternately during the cycle. As the strand tensions are balanced, no portion of the foot maintained is too tight or too loose.

Un avantage qui en découle est une tenue plus homogène du pied et une meilleure adaptation à la morphologie, par rapport à une chaussure selon l'art antérieur, aussi bien en mode statique que dynamique.A resulting advantage is a more uniform behavior of the foot and a better adaptation to the morphology, compared to a shoe according to the prior art, both in static and dynamic mode.

De manière complémentaire, il est précisé que le serrage du dispositif 20 est obtenu par traction selon les flèches F1, F2 sur le premier brin médial 31 et sur le deuxième brin médial 61. Bien entendu, le maintien du serrage est réalisé par tout moyen tel qu'un nouage, un blocage par tout dispositif approprié, ou autre, et le nombre de passants peut être modifié.In a complementary manner, it is specified that the tightening of the device 20 is obtained by traction according to arrows F1, F2 on the first medial strand 31 and on the second medial strand 61. Of course, the clamping is maintained by any means such as that a knot, a blocking by any suitable device, or other, and the number of passers-by can be modified.

Les autres formes de réalisation de l'invention sont présentées ci-après à l'aide des figures 4 à 11.The other embodiments of the invention are presented hereinafter with reference to FIGS. 4 to 11.

Pour des raisons de commodité, seules les différences par rapport à la première forme sont mises en évidence.For the sake of convenience, only the differences from the first form are highlighted.

La deuxième forme de réalisation est présentée à l'aide de la figure 4. Elle concerne simplement un changement de structure des moyens de connexion 46, 47, 48, 49 selon la première forme. Dans la deuxième forme, un au moins des moyens de connexion comprend un corps 80 évidé pour laisser passer des brins de lacet. En l'occurrence le corps 80 est traversé par un orifice 81 prévu pour guider plusieurs brins de lacet, par exemple au nombre de deux. L'orifice 81 peut présenter une section constante, pour faciliter sa production à l'aide d'une filière par exemple. L'orifice 81 peut alternativement présenter une section variable. Dans ce cas les extrémités peuvent être évasées, par rapport au centre plus réduit. La section variable offre une surface de guidage dont la courbure rappelle celle des boucles des brins de lacet.The second embodiment is presented with the aid of FIG. 4. It simply concerns a structural change of the connection means 46, 47, 48, 49 according to the first form. In the second form, at least one connecting means comprises a hollow body 80 for passing lace strands. In this case the body 80 is traversed by an orifice 81 provided for guiding a plurality of yaw strands, for example two in number. The orifice 81 may have a constant section, to facilitate its production using a die for example. The orifice 81 may alternatively have a variable section. In this case the ends can be flared, compared to the smaller center. The variable section offers a guiding surface whose curvature recalls that of the loops of the lace strands.

La troisième forme de réalisation est présentée à l'aide des figures 5 et 6.The third embodiment is presented using FIGS. 5 and 6.

Comme dans la première forme, on retrouve une chaussure 91 avec une semelle de marche 92, une tige 93, un talon 94, une pointe 95, un côté latéral 96, et un côté médial 97.As in the first form, there is a shoe 91 with a tread 92, a shank 93, a heel 94, a point 95, a lateral side 96, and a medial side 97.

La chaussure 91 comprend aussi une portion basse 100, un dessus 101, un quartier latéral 102, un quartier médial 103, et une languette 104.The shoe 91 also comprises a lower portion 100, a top 101, a lateral quarter 102, a medial quarter 103, and a tongue 104.

La chaussure 91 comprend encore un premier dispositif de serrage 110. Dans ce dispositif on retrouve, à l'image de celui selon la première forme, un premier brin de lacet latéral 111, ainsi qu'une première attache 112 et trois passants 113, 114, 115. Le dispositif de serrage 110 comprend aussi un premier brin de lacet médial 121, ainsi qu'une première attache 122 et un passant 123. Le dispositif de serrage 110 comprend encore un deuxième brin de lacet médial 131, ainsi qu'une première attache 132 et un passant 133.The shoe 91 also comprises a first clamping device 110. In this device, like the one according to the first form, there is a first lateral lace strand 111, as well as a first fastener 112 and three loops 113, 114 115. The clamping device 110 also includes a first medial yoke strand 121, as well as a first fastener 122 and a passer 123. The clamping device 110 further comprises a second medial yaw length 131, as well as a first attachment 132 and a passer 133.

Le premier dispositif de serrage 110 comprend également trois moyens de connexion 140, 141, 142 des brins entre eux.The first clamping device 110 also comprises three connection means 140, 141, 142 of the strands between them.

A la différence de la première forme de réalisation de l'invention, la chaussure 91 selon la deuxième forme comprend en plus un deuxième dispositif de serrage 150. Celui-ci 150 est destiné à serrer, de manière réversible, un emboîtage 151 de la chaussure 91. Bien entendu, l'emboîtage 151 est la portion de la chaussure destinée à accueillir le talon du pied de l'utilisateur.Unlike the first embodiment of the invention, the shoe 91 according to the second form further comprises a second clamping device 150. The latter 150 is intended to reversibly tighten a casing 151 of the shoe 91. Of course, the casing 151 is the portion of the boot for receiving the heel of the foot of the user.

Le deuxième dispositif de serrage 150 comprend un brin de lacet 152 qui contourne l'emboîtage 151. Ainsi le lacet 152 longe le quartier latéral 102, puis le talon 94, et enfin le quartier médial 103. Pour guider le lacet 152 autour de l'emboîtage 151, il est prévu un guide latéral 153, un guide arrière 154, et un guide médial 155. Chacun des guides 153, 154, 155 peut être fait d'un bloc ou bien de plusieurs parties associées, lesquelles sont juxtaposées ou espacées. Dans tous les cas un guide 153, 154, 155 impose au lacet 152 sa trajectoire.The second clamping device 150 comprises a lace strand 152 which bypasses the casing 151. Thus the lace 152 runs along the lateral quarter 102, then the heel 94, and finally the medial quarter 103. To guide the lace 152 around the casing 151, there is provided a lateral guide 153, a rear guide 154, and a medial guide 155. Each of the guides 153, 154, 155 may be made of a block or of several associated parts, which are juxtaposed or spaced apart. In all cases a guide 153, 154, 155 imposes on the lace 152 its trajectory.

De manière non limitative, les guides latéral 153 et médial 155 sont situés plus près de la semelle 92 que ne l'est le guide arrière 154. Ainsi, le serrage du lacet 152 provoque la flexion vers l'avant du talon 4 en même temps qu'une réduction du périmètre de l'entrée 156 de la chaussure 91.Without limitation, the lateral guides 153 and medial 155 are located closer to the sole 92 than is the rear guide 154. Thus, the tightening of the lace 152 causes forward bending of the heel 4 at the same time that a reduction of the perimeter of the entry 156 of the shoe 91.

Selon la troisième forme de réalisation de l'invention, les premier 110 et deuxième 150 dispositifs de serrage sont couplés.According to the third embodiment of the invention, the first 110 and second 150 clamping devices are coupled.

Un moyen de connexion latéral 160 relie l'un à l'autre le premier brin de lacet latéral 111 du premier dispositif 110 au brin de lacet 152 du deuxième dispositif 150. En fait les brins 111, 152 sont attachés l'un et l'autre au moyen de connexion 160, lequel n'est pas solidarisé à la tige 93. Le moyen de connexion 160 comprend aussi un passant 161 dans lequel passe le deuxième brin de lacet médial 131.A lateral connection means 160 connects the first lateral lace strand 111 of the first device 110 to the lace strand 152 of the second device 150. In fact, the strands 111, 152 are attached one to the other. other by means of connection 160, which is not secured to the rod 93. The connection means 160 also comprises a loop 161 in which passes the second medial lace strand 131.

Dans le même esprit un moyen de connexion médial 165 est relié à la tige 93, par un moyen de liaison comprenant deux attaches 166, 167 et un troisième brin de lacet médial 168. Ce dernier est très court, et confère au moyen de connexion médial 165 une certaine liberté d'orientation et de positionnement par rapport à la tige.In the same spirit a medial connection means 165 is connected to the rod 93, by a connecting means comprising two fasteners 166, 167 and a third medial lace strand 168. The latter is very short, and gives the means of medial connection 165 a certain freedom of orientation and positioning relative to the rod.

Le brin de lacet 152 du deuxième dispositif 150 est attaché au moyen de connexion médial 165, lequel comprend aussi un passant 169 dans lequel passe le premier brin de lacet médial 121.The lace strand 152 of the second device 150 is attached to the medial connection means 165, which also includes a loop 169 through which the first medial yarn strand 121 passes.

Le couplage des deux dispositifs de serrage 110, 150 permet de serrer simultanément le dessus 101, dans la zone de la languette 104, et l'emboîtage 151. Une traction du premier brin de lacet médial 121 et du deuxième 131 brin de lacet médial, selon les flèches F3, F4, engendre non seulement le serrage du premier dispositif 110, comme expliqué pour la première forme, mais aussi le serrage du deuxième dispositif 150. En effet, les efforts F3, F4 engendrent des tractions sur le premier brin de lacet latéral 111. Par répercussion le brin de lacet 152 du deuxième dispositif se tend.The coupling of the two clamping devices 110, 150 makes it possible to simultaneously clamp the top 101, in the zone of the tongue 104, and the casing 151. A traction of the first medial lace strand 121 and the second medial lace strand 131, according to the arrows F3, F4, not only causes the tightening of the first device 110, as explained for the first form, but also the tightening of the second device 150. Indeed, the forces F3, F4 cause traction on the first yaw Lateral 111. By repercussion lace yarn 152 of the second device stretches.

Bien entendu, là encore le serrage est maintenu par tout moyen connu. Un avantage de la troisième forme de réalisation est l'obtention d'un serrage global avec deux brins de lacet. On peut également envisager de dissocier les deux dispositifs de serrage 110 et 150.Of course, here again the clamping is maintained by any known means. An advantage of the third embodiment is to obtain overall tightening with two yarn strands. It is also possible to separate the two clamping devices 110 and 150.

La quatrième forme de réalisation est présentée à l'aide de la figure 7.The fourth embodiment is presented with the aid of FIG.

On retrouve, comme pour la troisième forme, une chaussure 181 avec un premier 182 et un deuxième 183 dispositifs de serrage. La particularité de cette chaussure 181 est de présenter une tige haute, avec une portion de tige basse 184 et une portion de tige haute 185. Des passants 186 sont disposés sur la portion haute 185 pour étendre le champ d'action du premier dispositif de serrage 182.There is, as for the third form, a shoe 181 with a first 182 and a second 183 clamping devices. The peculiarity of this shoe 181 is to present a high stem, with a low stem portion 184 and a high stem portion 185. Passers 186 are disposed on the upper portion 185 to extend the field of action of the first clamping device 182.

La cinquième forme de réalisation propose un premier dispositif de serrage 200 simplifié, présenté à l'aide de la figure 8.The fifth embodiment proposes a first simplified clamping device 200, presented with the help of FIG. 8.

Le dispositif 200 comprend un premier brin de lacet latéral 201, lequel suit un chemin qui passe successivement par une première attache 202, deux passants 203, 204, et une deuxième attache 205. Le dispositif 200 comprend aussi un premier brin de lacet médial 206, lequel chemine depuis une première attache 207 pour passer par deux passants 208, 209, et présenter ensuite une extrémité libre 210. Trois moyens de connexion 211, 212, 213 relient l'un à l'autre les brins de lacet 201, 206 entre les passants. Il suffit de tirer sur l'extrémité libre 210 pour serrer le dispositif 200, dans le sens de la flèche F5. Une particularité de cette forme de réalisation est d'obtenir le serrage par traction sur un seul brin du lacet médial 206. En effet le premier brin de lacet 201 sert en fait à former le passant à géométrie variable, tandis que le premier brin de lacet médial 206 sert à exercer le serrage proprement dit par traction sur son extrémité libre 210.The device 200 comprises a first lateral lace strand 201, which follows a path which successively passes through a first fastener 202, two loops 203, 204, and a second fastener 205. The device 200 also comprises a first medial lace strand 206, which travels from a first fastener 207 to pass through two loops 208, 209, and then present a free end 210. Three connecting means 211, 212, 213 connect to each other the yaw strands 201, 206 between the passersby. Just pull on the free end 210 to tighten the device 200, in the direction of the arrow F5. A peculiarity of this embodiment is to obtain the traction tightening on a single strand of the medial lace 206. Indeed the first lace strand 201 serves in fact to form the variable geometry passer, while the first strand of lace medial 206 serves to exert the proper clamping by pulling on its free end 210.

Bien entendu, il peut être prévu un nombre différent de passants et de moyens de connexion.Of course, it may be provided a different number of passers and connection means.

La sixième forme de réalisation, tournée vers un autre premier dispositif de serrage 220 simplifié, est présentée à l'aide de la figure 9.The sixth embodiment, facing another simplified first clamping device 220, is shown with reference to FIG. 9.

Le dispositif 220 comprend un lacet unique 221 ayant un brin latéral et un brin médial, quatre passants latéraux 222, 223, 224, 225, un passant avant 226, et quatre passants médiaux 227, 228, 229, 230. Le lacet 221 passe par ses brins respectivement latéral et médial successivement par les quatre passants latéraux 222, 223, 224, 225, par le passant avant 226, puis par les quatre passants médiaux 227, 228, 229, 230. Trois moyens de connexion 240, 241, 242 relient l'une à l'autre une subdivision latérale 243 et une subdivision médiale 244 du lacet 221, entre les passants. Une extrémité latérale 245 et une extrémité médiale 246 du lacet 221 permettent de serrer le dispositif 220, par traction selon les flèches F6, F7. Par rapport aux formes de réalisation précédentes, le lacet 221 sert uniquement au serrage et ne forme pas de passant mobile le long d'un quartier de la tige, les seuls éléments mobiles étant les moyens de connexion mobiles.The device 220 comprises a single lace 221 having a lateral strand and a medial strand, four lateral loops 222, 223, 224, 225, a front passer 226, and four medial loops 227, 228, 229, 230. The lace 221 passes through its strands respectively lateral and medial successively by the four lateral loops 222, 223, 224, 225, by the forward passer 226, then by the four medial loops 227, 228, 229, 230. Three connection means 240, 241, 242 connect to each other a lateral subdivision 243 and a medial subdivision 244 of the lace 221, between the passers-by. A lateral end 245 and a medial end 246 of the lace 221 make it possible to tighten the device 220, by traction according to the arrows F6, F7. Compared to the previous embodiments, the lace 221 serves only for clamping and does not form a movable loop along a quarter of the rod, the only moving elements being the mobile connection means.

Bien entendu, là encore les nombres de passants et de moyens de connexion peuvent être différents.Of course, again the numbers of passers and connection means may be different.

La septième forme de réalisation propose aussi un premier dispositif de serrage 260 simplifié, présenté à l'aide de la figure 10.The seventh embodiment also proposes a first simplified clamping device 260, presented with the aid of FIG.

Le dispositif 260 comprend un lacet unique 261, ainsi qu'une première attache latérale 262 située près de l'entrée de la chaussure, trois passants latéraux 263, 264, 265, un passant avant 266, et quatre passants médiaux 267, 268, 269, 270. Le lacet 261 suit un chemin qui part de l'attache latérale 262, puis passe successivement par les trois passants latéraux 263, 264, 265, par le passant avant 266, puis par les quatre passants médiaux 267, 268, 269, 270. Trois moyens de connexion 280, 281, 282 relient l'une à l'autre une subdivision latérale 283 et une subdivision médiale 284 du lacet 261, entre les passants. Une extrémité médiale 285 du lacet 261 permet de serrer le dispositif 260, par traction selon la flèche F8. La différence par rapport à la forme de réalisation selon la figure 9 est que le serrage s'effectue par traction sur une seule extrémité 285 du lacet 261 du fait de la fixation de l'autre extrémité par la première attache 262.The device 260 comprises a single lace 261, and a first lateral attachment 262 located near the entrance of the shoe, three lateral loops 263, 264, 265, a front passer 266, and four medial passers 267, 268, 269, 270. The lace 261 follows a path that starts from the lateral attachment 262, then passes successively through the three lateral loops 263, 264, 265, by the passer before 266, then by the four medial passers 267, 268, 269, 270. Three connecting means 280, 281, 282 connect to each other a lateral subdivision 283 and a medial subdivision 284 of the lace 261 between the loops. A medial end 285 of the lace 261 makes it possible to tighten the device 260 by traction along the arrow F8. The difference with respect to the embodiment according to Figure 9 is that the tightening is performed by pulling on one end 285 of the lace 261 due to the fixing of the other end by the first fastener 262.

Encore une fois les nombres de passants et de moyens de connexion peuvent être différents.Once again the numbers of passers-by and means of connection may be different.

La huitième forme de réalisation propose un premier dispositif de serrage 300, équivalent à celui selon la première forme, présenté à l'aide de la figure 11.The eighth embodiment proposes a first clamping device 300, equivalent to the one according to the first form, presented with the help of FIG.

Le premier dispositif de serrage 300 comprend un premier brin de lacet latéral 301, une première attache latérale 302, trois passants latéraux 303, 304, 305, et une deuxième attache latérale 306. Le dispositif de serrage 300 comprend aussi un premier brin de lacet médial 311, une première attache médiale 312, un premier passant médial 313 et un deuxième passant médial 314 pour le premier brin médial 311, ainsi qu'un deuxième brin de lacet médial 321, une première attache médiale 322, et un premier passant médial 323 pour le deuxième brin médial 321.The first clamping device 300 comprises a first side lace strand 301, a first side fastener 302, three side loops 303, 304, 305, and a second side fastener 306. The clamp 300 also includes a first medial lace strand 311, a first medial clip 312, a first medial passer 313 and a second medial passer 314 for the first medial strand 311, and a second medial lace strand 321, a first medial clip 322, and a first medial passer 323 for the second medial strand 321.

Quatre moyens de connexion 330, 331, 332, 333 connectent le lacet latéral 301 avec le premier lacet médial 311, ou bien avec le deuxième lacet médial 321, dans un esprit similaire à celui de la première forme de réalisation.Four connecting means 330, 331, 332, 333 connect the lateral lace 301 with the first medial lace 311, or with the second medial lace 321, in a spirit similar to that of the first embodiment.

La particularité des moyens de connexion, selon la huitième forme, est liée à leur structure. Un moyen de connexion 330, 331, 332, 333 est réalisé par passage d'un brin 301, 311, 321 autour de l'autre. En d'autres termes les deux lacets médiaux 311, 321 servent à réaliser le serrage, tandis que le lacet latéral 301 sert à former le passant latéral à géométrie variable et les moyens de connexion mobiles. Bien entendu les brins glissent les uns par rapport aux autres pour équilibrer les tensions dans le dispositif 300. Chaque brin peut comprendre des matériaux à faible coefficient de frottement, pour faciliter les glissements. Par exemple du polyéthylène convient, au moins pour la surface du brin.The particularity of the connection means, according to the eighth form, is related to their structure. A connection means 330, 331, 332, 333 is made by passing one strand 301, 311, 321 around the other. In other words, the two medial laces 311, 321 serve to effect the tightening, while the lateral lace 301 serves to form the variable geometry lateral passer and the mobile connection means. Of course the strands slide relative to each other to balance the voltages in the device 300. Each strand can include low friction materials, to facilitate sliding. For example polyethylene is suitable, at least for the surface of the strand.

Dans tous les cas l'invention est réalisée à partir de matériaux et selon des techniques de mise en oeuvre connus de l'homme du métier.In all cases the invention is made from materials and according to processing techniques known to those skilled in the art.

Bien entendu l'invention n'est pas limitée aux formes de réalisation ci-avant décrites, et comprend tous les équivalents techniques pouvant entrer dans la portée des revendications qui vont suivre.Naturally, the invention is not limited to the embodiments described above, and includes all technical equivalents that fall within the scope of the claims that follow.

En particulier dans tous les cas l'architecture d'un dispositif de serrage peut être inversée, dans le sens où les spécificités liées à un côté médial peuvent se retrouver sur un côté latéral et vice versa.In particular in all cases the architecture of a clamping device can be reversed, in the sense that the specificities related to a medial side can be found on a lateral side and vice versa.

On peut également envisager une construction dans laquelle des passants à géométrie variable sont formés avec des brins de lacets sur chacun des côtés respectivement latéral et médial de la tige, en plus des moyens de connexion mobiles.It is also possible to envisage a construction in which loops of variable geometry are formed with strands of laces on each of the lateral and medial sides respectively of the rod, in addition to the mobile connection means.

Un dispositif de serrage peut être centré transversalement par rapport à la tige, ou bien décalé vers le côté latéral ou vers le côté médial.A clamping device may be centered transversely to the shaft, or offset to the lateral or medial side.

Un dispositif peut être rectiligne, ou former des ondulations transversales.A device can be rectilinear, or form transverse corrugations.

Les différents points de liaison, du dispositif de serrage à la tige, peuvent être alignés transversalement ou bien décalés.The different points of connection, from the clamping device to the rod, can be aligned transversely or shifted.

Les distances entre les points de liaison, d'un même côté de la chaussure, peuvent être identiques ou différentes.The distances between the connection points on the same side of the shoe may be identical or different.

On peut généraliser l'invention en écrivant qu'un lacet comprend au moins un brin qui passe alternativement par des passants respectivement latéraux et médiaux, le brin passant par au moins un moyen de connexion mobile entre les passants.It is possible to generalize the invention by writing that a lace comprises at least one strand which passes alternately by passers respectively lateral and medial, the strand passing through at least one means of mobile connection between passers.

On peut préciser aussi qu'au moins un passant est mobile par rapport à la tige.It can also be specified that at least one passer is movable relative to the rod.

Dans tous les cas un lacet ou un brin de lacet peut comprendre de la corde, de la ficelle, de la sangle, du câble, du fil comprenant toute matière. Le lacet est donc un lien ou un morceau de lien au sens large.In all cases a lace or a yarn may comprise rope, string, strap, cable, wire including any material. The lace is therefore a link or a piece of link in the broad sense.
