Abstract

A boot having an external sole on which is mounted an upper open towards to the front, to enable passage of the foot and including to this end, an internal and an external quarter connected to each other by a closure system which includes a flexible link along a predetermined alternative path, a series of return elements located in a fixed manner on each side of the quarters in the vicinity of their respective edges located across from each other and defining a lacing zone, such that when an action is exerted on the two free ends (A, B) of the slack ends of the flexible link via traction members, such members tighten quarters, via return elements, so as to bring them closer to one another and consequently ensure internal retention of the foot, wherein the lacing zone can be broken down into three tightening sectors, i.e., a first primary tightening sector; a second primary tightening sector; and a third secondary tightening sector whose tightening is undertaken after that of the first and second sectors by the progressive transmission of traction forces exerted on the slack ends of the flexible link from their free ends.

Description

La présente invention concerne une chaussure notamment de sport comprenant une semelle externe sur laquelle est montée une tige ouverte vers l'avant, pour permettre le passage du pied et comportant à cet effet un quartier interne et un quartier externe reliés entre eux par un système de fermeture, constitué par un lacet ou câble, selon un parcours alternatif déterminé, une série d'éléments de renvoi disposés de façon fixe de part et d'autre desdits quartiers à proximité de leurs bords respectifs situés en vis à vis et définissant une zone de laçage, de manière que lors d'une action sur les deux extrémités libres des brins du lacet ou câble s'effectuant par traction, celui-ci agisse en serrage sur les quartiers, par l'intermédiaire des éléments de renvoi, pour les rapprocher l'un de l'autre et assurer en conséquence une tenue du pied.The present invention relates to a shoe, in particular a sport shoe, comprising an external sole on which is mounted a rod open towards the front, to allow the passage of the foot and comprising for this purpose an internal quarter and an external quarter linked together by a system of closure, constituted by a lace or cable, according to a determined alternative route, a series of deflection elements arranged in a fixed manner on either side of said districts near their respective edges located opposite and defining a zone of lacing, so that during an action on the two free ends of the strands of the lace or cable being effected by traction, the latter acts in clamping on the quarters, by means of the return elements, to bring them closer together. 'from each other and ensure foot support accordingly.

Dans les chaussures de sport connues de ce type (voir par exemple US-A-4 780 969), le laçage s'effectue par exemple (voir illustration de la figure 1) selon une méthode classique consistant à croiser régulièrement chacun des brins du lacet 20 après les avoir passés dans des oeillets ou derrière des plots situés en vis à vis sur chacun des quartiers 12, 13 de la tige et selon une progression régulière de l'avant (AV) vers l'arrière (AR) de la chaussure.In known sports shoes of this type (see for example US-A-4,780,969), the lacing is carried out for example (see illustration of FIG. 1) according to a conventional method consisting in regularly crossing each of the strands of the lace. 20 after having passed them through eyelets or behind studs located opposite each of the quarters 12, 13 of the upper and according to a regular progression from the front (AV) to the rear (AR) of the shoe.

Une autre méthode également très répandue (voir illustration de la figure 2) consiste à faire passer l'un 24 des brins du lacet 20, directement d'un premier oeillet 21 de l'un des quartiers 12 de la tige, situé vers l'arrière à un dernier oeillet 22 de l'autre quartier 13 de la tige, situé vers l'avant. Dans ce cas de figure, c'est l'autre brin 23 du lacet qui rejoint tous les autres oeillets ou plots en zig zagant d'un quartier à l'autre de la tige sur toute la longueur de la zone de laçage pour provoquer le rapprochement desdits quartiers 12, 13.Another also very widespread method (see illustration of FIG. 2) consists in passing one 24 of the strands of the lace 20, directly from a first eyelet 21 of one of the quarters 12 of the upper, located towards the rear to a last eyelet 22 of the other quarter 13 of the rod, located towards the front. In this case, it is the other strand 23 of the lace which joins all the other eyelets or studs in a zig zagging from one quarter to the other of the rod over the entire length of the lacing zone to cause the approximation of said districts 12, 13.

Si ces méthodes de laçage donnent satisfaction pour les chaussures ayant une zone de laçage de faible longueur, il n'en est pas de même lorsque celle-ci devient plus conséquente, comme par exemple dans les chaussures de montagne, de ski de fond ou dans celles destinées à la pratique du basket-ball, qui requièrent une tenue importante du pied, donc une zone de serrage plus longue.If these lacing methods are satisfactory for shoes with a lacing area of short length, it is not the same when it becomes more substantial, as for example in mountain boots, cross-country skiing or in those intended for the practice of basketball, which require a significant holding of the foot, therefore a longer tightening zone.

Dans ces cas, les méthodes précitées présentent un inconvénient majeur, car lorsque le laçage est long, la traction sur le ou les brins en zig-zag doit être d'autant plus importante que ces derniers sont nombreux. De plus, il est impossible de maîtriser le serrage pour sa bonne répartition sur toute la longueur de la zone de laçage.In these cases, the aforementioned methods have a major drawback, because when the lacing is long, the pull on the zig-zag strand or strands must be all the more important as the latter are numerous. In addition, it is impossible to control the tightening for its good distribution over the entire length of the lacing area.

Pour remédier à cela, l'utilisateur doit procéder au serrage de sa chaussure, non pas en exercant une traction sur les extrémités libres des brins du lacet, mais en intervenant directement sur chacune des boucles formées par celui-ci entre deux oeillets ou plot en vis à vis, de manière à serrer successivement, ces boucles de proche en proche jusqu'aux derniers oeillets situés vers la partie avant de la chaussure. Eventuellement ce serrage pourra être effectué par action sur une bouche sur deux, mais en tout état de cause, le serrage définitif des lacets de chaque chaussure s'avèrera long et fastidieux.To remedy this, the user must tighten his shoe, not by exerting traction on the free ends of the strands of the lace, but by acting directly on each of the loops formed by it between two eyelets or stud in opposite, so as to successively tighten these loops step by step until the last eyelets located towards the front of the shoe. This tightening may possibly be carried out by acting on one mouth in two, but in any event, the final tightening of the laces of each shoe will prove to be long and tedious.

La présente invention vise à remédier à ces inconvénients en proposant un dispositif de laçage permettant par une action unique, effectuée simultanément sur les extrémités libres des brins du lacet ou câble, d'obtenir un serrage aisé et réparti de manière contrôlée, uniformément sur toute la longueur de la zone de laçage.The present invention aims to remedy these drawbacks by proposing a lacing device allowing, by a single action, carried out simultaneously on the free ends of the strands of the lace or cable, to obtain an easy tightening and distributed in a controlled manner, uniformly over the whole length of the lacing area.

A cet effet, l'invention concerne une chaussure du type précité se caractérisant en ce que la zone de laçage se décompose en trois secteurs de serrage à savoir :

  • un premier secteur de serrage primaire dirigé vers l'avant de la chaussure, correspondant sensiblement à la zone d'articulation des métatarses du pied et constituant une partie inférieure de la zone de laçage directement sollicitée par un premier brin du lacet ou câble lors d'une traction exercée sur celui-ci à partir de son extrémité libre,
  • un second secteur de serrage primaire dirigé vers l'arrière de la chaussure, correspondant sensiblement à la zone du pli de flexion du pied et constituant une partie supérieure de la zone de laçage directement sollicitée par le second brin du lacet ou câble lors d'une traction exercée sur celui-ci, les brins exerçant une action simultanée sur lesdits premier et second secteurs de serrage primaire, à partir de leurs extrémités libres,
  • un troisième secteur de serrage secondaire situé entre les premier et second secteurs, correspondant sensiblement à la zone du cou-de-pied et constituant une partie centrale de la zone de laçage, dont le serrage s'effectue successivement à celui des premier et second secteurs par transmission progressive des forces de traction exercées sur lesdits brins du lacet ou câble à partir de leurs extrémités libres.
To this end, the invention relates to a shoe of the aforementioned type, characterized in that the lacing zone is broken down into three tightening sectors, namely:
  • a first primary tightening sector directed towards the front of the shoe, corresponding substantially to the articulation zone of the metatarsals of the foot and constituting a lower part of the lacing zone directly stressed by a first strand of the lace or cable during a traction exerted on it from its free end,
  • a second primary tightening sector directed towards the rear of the shoe, corresponding substantially to the area of the flexion of the foot and constituting an upper part of the lacing area directly stressed by the second strand of the lace or cable during a traction exerted on it, the strands exerting a simultaneous action on said first and second primary clamping sectors, from their free ends,
  • a third secondary tightening sector located between the first and second sectors, corresponding substantially to the instep area and constituting a central part of the lacing area, the tightening of which is carried out successively to that of the first and second sectors by progressive transmission of the tensile forces exerted on said strands of the lace or cable from their free ends.

L'invention sera mieux comprise et d'autres caractéristiques de celle-ci seront mises en évidence à l'aide de la description qui suit, en référence aux dessins schématiques annexés, illustrant, à titre d'exemple non limitatif, comment l'invention peut-être réalisée et dans lesquels :

La chaussure de sport désignée dans son ensemble et représentée sur la figure 3 comprend une semelle externe 10 sur laquelle est montée une tige 11 ouverte vers l'avant, pour permettre le passage du pied et comportant à cet effet un quartier interne 12 et un quartier externe 13 reliés entre eux par un système de fermeture 14 constitué en l'occurrence par un lacet 15 formant deux brins 15a et 15b reliant entre eux, selon un parcours déterminé, une série d'éléments de renvoi 1 à 7 disposés fixement de part et d'autre desdits quartiers 12, 13, à proximité de leurs bords respectifs 12a, 13a situés en vis à vis. Ces bords 12a, 13a définissent entre eux une zone de laçage 16, de manière que lors d'une action sur les extrémités libres A, B des brins 15a et 15b du lacet 15, s'effectuant par l'intermédiaire de moyens de traction 17, ceux-ci agissent en serrage sur les quartiers 12, 13, par l'intermédiaire des éléments de renvoi 1 à 7. Ainsi, lesdits quartiers sont rapprochés l'un de l'autre et assurent conséquemment une tenue du pied à l'intérieur de la chaussure.The sports shoe designated as a whole and represented in FIG. 3 comprises an external sole 10 on which is mounted a rod 11 open towards the front, to allow the passage of the foot and comprising for this purpose an internal quarter 12 and a quarter external 13 connected to each other by a closure system 14 constituted in this case by a lace 15 forming two strands 15a and 15b connecting together, according to a determined route, a series of return elements 1 to 7 fixedly fixed in part and other of said districts 12, 13, near their respective edges 12a, 13a located opposite. These edges 12a, 13a define between them a lacing zone 16, so that during an action on the free ends A, B of the strands 15a and 15b of the lace 15, effected by means of traction means 17 , these act in clamping on the quarters 12, 13, by means of the return elements 1 to 7. Thus, the said quarters are brought closer to one another and consequently ensure a holding of the foot inside. of the shoe.

Selon l'invention, la zone de laçage 16 se décompose en trois secteurs de serrage à savoir :

  • un premier secteur de serrage primaire P1 dirigé vers l'avant (AV) de la chaussure, correspondant sensiblement à la zone d'articulation des métatarses du pied et constituant une partie inférieure de la zone de laçage 16 directement sollicitée par l'un 15b des brins du lacet 15 lors d'une traction exercée sur celui-ci à partir de son extrémité libre B (voir figure 4),
  • un second secteur de serrage primaire P2 dirigé vers l'arrière (AR) de la chaussure, correspondant sensiblement à la zone du pli de flexion du pied et constituant une partie supérieure de la zone de laçage 16 directement sollicitée par l'autre brin 15a du lacet 15 lors d'une traction exercée sur celui-ci, les brins 15a, 15b exerçant une traction simultanée sur lesdits premier et second secteurs, respectivement P1, P2, de serrage primaire, à partir de leurs extrémités libres A, B (voir figure 5),
  • un troisième secteur de serrage secondaire S situé entre les premier et second secteurs P1, P2, correspondant sensiblement à la zone du cou-de-pied et constituant une partie centrale C de la zone de laçage 16, dont le serrage s'effectue successivement à celui des premier et second secteurs P1, P2 par transmission progressive des forces de traction exercées sur les brins 15a et 15b du lacet 15 à partir de leurs extrémités libres A, B (voir figure 6).
According to the invention, the lacing zone 16 is divided into three tightening sectors, namely:
  • a first primary tightening sector P1 directed towards the front (AV) of the shoe, corresponding substantially to the articulation zone of the metatarsals of the foot and constituting a lower part of the lacing zone 16 directly biased by one of the strands of the lace 15 during a traction exerted thereon from its free end B (see FIG. 4),
  • a second primary tightening sector P2 directed towards the rear (AR) of the shoe, corresponding substantially to the area of the flexion fold of the foot and constituting an upper part of the lacing area 16 directly stressed by the other strand 15a of the lace 15 during a traction exerted on it, the strands 15a, 15b exerting a simultaneous traction on said first and second sectors, respectively P1, P2, of primary tightening, from their free ends A, B (see figure 5),
  • a third secondary clamping sector S situated between the first and second sectors P1, P2, corresponding substantially to the instep zone and constituting a central part C of the lacing zone 16, the clamping of which is carried out successively at that of the first and second sectors P1, P2 by progressive transmission of the tensile forces exerted on the strands 15a and 15b of the lace 15 from their free ends A, B (see FIG. 6).

Plus précisément et selon le présent exemple de réalisation, le premier secteur de serrage primaire P1 comprend au moins trois éléments de renvoi 5, 6, 7 dont deux 6, 7 situés de part et d'autre des quartiers interne 12 et externe 13 sont dirigés vers l'avant (AV) de la chaussure et sont reliés entre eux par une boucle d'extrémité I, commune aux deux brins 15a, 15b du lacet 15. Le troisième élément de renvoi 5 est dirigé vers l'arrière (AR) de la chaussure relativement aux précédents, et l'un des brins 15b forme, à partir de ce renvoi 5 et après avoir contourné l'un des éléments précédents 6, une double boucle inversée I, II, III dont l'extrémité libre B est directement reliée aux moyens de traction 17 (voir figure 4).More precisely and according to the present embodiment, the first primary clamping sector P1 comprises at least three deflection elements 5, 6, 7 two of which 6, 7 located on either side of the inner 12 and outer 13 quarters are directed towards the front (AV) of the boot and are connected together by an end loop I, common to the two strands 15a, 15b of the lace 15. The third return element 5 is directed towards the rear (AR) of the shoe relative to the preceding ones, and one of the strands 15b forms, from this return 5 and after having bypassed one of the previous elements 6, an inverted double loop I, II, III, the free end B of which is directly connected to the traction means 17 (see FIG. 4).

Par ailleurs, le second secteur de serrage primaire P2 comprend au moins deux éléments de renvoi 1, 2 disposés vers l'arrière (AR) de ladite chaussure de part et d'autre des quartiers interne 12 et externe 13 de la tige 11, et réunis entre eux par une double boucle inversée IV, V, VI formée par un des brins 15a du lacet ou câble 15 dont l'extrémité libre A est directement reliée aux moyens de traction 17 (voir figure 5).Furthermore, the second primary clamping sector P2 comprises at least two deflection elements 1, 2 arranged towards the rear (AR) of said shoe on either side of the internal 12 and external 13 quarters of the upper 11, and joined together by a double inverted loop IV, V, VI formed by one of the strands 15a of the lace or cable 15 whose free end A is directly connected to the traction means 17 (see FIG. 5).

Par ailleurs, le troisième secteur de serrage secondaire S comprend au moins deux éléments de renvoi 3, 4 disposés de part et d'autre des quartiers interne 12 et externe 13, dans une zone intermédiaire C, réunis entre eux par une double boucle inversée IV, VII, VIII formée par un des brins 15a du lacet ou câble 15 (voir figure 6).Furthermore, the third secondary clamping sector S comprises at least two deflection elements 3, 4 arranged on either side of the internal 12 and external 13 quarters, in an intermediate zone C, joined together by a double inverted loop IV , VII, VIII formed by one of the strands 15a of the lace or cable 15 (see FIG. 6).

Ainsi et en résumé, le brin 15a forme à partir de son extrémité libre A, les boucles successives VI, V, IV, VII, VIII et le brin 15b forme à partir de son extrémité libre B, les boucles successives III, II, I.Thus and in summary, the strand 15a forms from its free end A, the successive loops VI, V, IV, VII, VIII and the strand 15b forms from its free end B, the successive loops III, II, I .

Comme on l'en déduit par ce qui précède, les éléments de renvoi 1 à 7 sont donc en nombre impair, l'un des quartiers 12 en comprenant un nombre n + 1 : soit quatre, 1, 3, 5, 7, par rapport à l'autre 13 en comprenant un nombre n : soit trois, 2, 4, 6. Ainsi que le montrent les figures 4 à 7, les éléments de renvoi sont disposés de façon décalée sur les quartiers en vis à vis pour avoir un trajet sensiblement horizontal des boucles I, II,......VIII.As can be deduced from the above, the reference elements 1 to 7 are therefore in an odd number, one of the districts 12 comprising a number n + 1: that is to say four, 1, 3, 5, 7, by relative to the other 13 by including a number n: that is to say three, 2, 4, 6. As shown in FIGS. 4 to 7, the deflection elements are arranged in an offset fashion on the opposite quarters in order to have a substantially horizontal path of loops I, II, ...... VIII.

Selon le présent exemple, les éléments de renvoi 1 à 7 sont au moins au nombre de sept, dont quatre 1, 3, 5, 7 sont disposés sur l'un des quartiers 12 de la tige 11 et trois, 2, 4, 6 sur l'autre quartier 13 mais comme le montre bien la figure 8, on peut aisément imaginer que les éléments de renvoi 3, 5, 7 et 2, 4, 6 de chacun des quartiers 12, 13 de la tige 11 soient disposés en vis à vis à l'exception de l'un d'eux 1 dirigé vers l'arrière (AR) de la chaussure.According to the present example, the return elements 1 to 7 are at least seven in number, of which four 1, 3, 5, 7 are arranged on one of the quarters 12 of the rod 11 and three, 2, 4, 6 on the other quarter 13 but as shown in FIG. 8, one can easily imagine that the return elements 3, 5, 7 and 2, 4, 6 of each of the quarters 12, 13 of the rod 11 are arranged in screws with the exception of one of them 1 directed towards the rear (AR) of the shoe.

Selon un exemple de réalisation, les moyens de traction 17 sont constitués par un dispositif de verrouillage mécanique solidaire de la chaussure et actionné par un levier tendeur en liaison avec les extrémités libres A, B des brins 15a, 15b du lacet 15.According to an exemplary embodiment, the traction means 17 are constituted by a mechanical locking device secured to the boot and actuated by a tensioning lever in connection with the free ends A, B of the strands 15a, 15b of the lace 15.

Dans ce cas, un élément de guidage 18 peut être prévu, solidaire de l'un des quartiers 13 comportant n éléments de renvoi et interposé entre le dispositif de verrouillage 17 et les premiers éléments de renvoi 1, 2 de chacun des brins 15a, 15b du lacet ou câble 15.In this case, a guide element 18 may be provided, integral with one of the quarters 13 comprising n return elements and interposed between the device locking 17 and the first return elements 1, 2 of each of the strands 15a, 15b of the lace or cable 15.

Bien entendu, comme le montre la figure 9, les moyens de traction peuvent également être manuels, l'immobilisation des brins 15a et 15b du lacet 15 s'effectuant par un noeud 19 pratiqué aux extrémités A, B desdits brins.Of course, as shown in FIG. 9, the traction means can also be manual, the immobilization of the strands 15a and 15b of the lace 15 being effected by a knot 19 made at the ends A, B of said strands.

Comme le montre également cette figure, les éléments de renvoi peuvent également être au nombre de neuf, les deux éléments supplémentaires 8, 9 faisant partie ici du serrage primaire P1, mais ils pourraient être disposés de sorte à faire partie de l'une ou l'autre des zones de serrage P2 ou S.As this figure also shows, there are also nine return elements, the two additional elements 8, 9 being part of the primary clamping P1 here, but they could be arranged so as to be part of one or the other. other of the P2 or S tightening zones

Selon une variante de réalisation, les éléments de renvoi 1 à 9 sont des pots sertis sur les quartiers 12, 13 de la tige 11 et aptes à être contournés par les brins 15a, 15b du lacet ou câble 15.According to an alternative embodiment, the return elements 1 to 9 are pots crimped onto the quarters 12, 13 of the rod 11 and capable of being circumvented by the strands 15a, 15b of the lace or cable 15.

Selon une autre variante, les éléments de renvoi 1 à 9 sont des oeillets réalisés sur les quartiers 12, 13 de la tige 11 et aptes à être traversés par les brins 15a, 15b du lacet ou câble 15.According to another variant, the return elements 1 to 9 are eyelets produced on the quarters 12, 13 of the rod 11 and capable of being crossed by the strands 15a, 15b of the lace or cable 15.

Dans tous les cas de figures, chacun des éléments de renvoi 1 à 9 ne supporte qu'un seul brin 15a, 15b du lacet ou câble 15.In all cases, each of the return elements 1 to 9 supports only one strand 15a, 15b of the lace or cable 15.

Ceci permet d'éviter tout emmêlage du lacet 15 et également toute surpression au niveau du pied.This avoids any tangling of the lace 15 and also any overpressure at the foot.

On comprend bien selon la description qui précède que le parcours de serrage défini par le lacet, par rapport aux éléments de renvoi permet lors du verrouillage du levier tendeur du dispositif 17, de serrer dans un premier temps, les deux zones de serrage primaires P1, P2 simultanément, et ensuite d'agir sur la zone intermédiaire secondaire S.It is clearly understood from the foregoing description that the tightening path defined by the lace, relative to the deflection elements makes it possible, when locking the tensioning lever of the device 17, to first tighten the two primary tightening zones P1, P2 simultaneously, and then to act on the secondary intermediate zone S.

Ainsi, lorsqu'une traction est exercée sur le brin 15a du lacet 15, celui-ci se déplace par exemple d'une distance "d" (voir figure 4). Ledit brin 15a déplace en premier lieu, successivement l'élément de renvoi 1, puis 2, puis 3, etc.... Ceci a pour conséquence de déplacer :

  • l'élément 1 vers 2 et levier 17 = effet primaire P2,
  • l'élément 3 vers 2 et 4 = effet secondaire S.
Thus, when traction is exerted on the strand 15a of the lace 15, the latter moves for example by a distance "d" (see FIG. 4). Said strand 15a moves in the first place, successively the deflection element 1, then 2, then 3, etc. This has the consequence of moving:
  • element 1 to 2 and lever 17 = primary effect P2,
  • element 3 to 2 and 4 = side effect S.

Simultanément, le brin 15b déplace en premier lieu successivement l'élément 5, puis 6, puis 7, etc.... Ceci a pour conséquence de déplacer :

  • l'élément 6 vers 7 et 5 = effet primaire P2,
  • l'élément 4 vers 5 et 3 = effet secondaire S.
Simultaneously, the strand 15b first moves the element 5 successively, then 6, then 7, etc. This has the consequence of moving:
  • element 6 to 7 and 5 = primary effect P2,
  • element 4 to 5 and 3 = side effect S.

Etant donné que les brins 15a et 15b se déplacent en même temps, le serrage se fait donc d'abord en deux zones P1, P2, puis progressivement en une zone intermédiaire secondaire S.Since the strands 15a and 15b move at the same time, the tightening is therefore done first in two zones P1, P2, then gradually in a secondary intermediate zone S.

Cela permet bien d'effectuer le serrage simultanément à l'avant et à l'arrière du cou-de-pied, puis progressivement, sans effort supplémentaire sur le cou-de-pied. Il est ainsi avantageusement obtenu un serrage bi-actif.This makes it possible to perform the tightening simultaneously at the front and at the rear of the instep, then gradually, without additional effort on the instep. It is thus advantageously obtained a bi-active tightening.

Par ailleurs, le serrage ainsi réalisé permet une répartition de la tension de serrage plus homogène tout en étant effectué très rapidement et sans surpression aucune au niveau du pied.Furthermore, the tightening thus produced allows a more uniform distribution of the tightening tension while being carried out very quickly and without any overpressure at the level of the foot.

Des câbles en polyamide seront utilisés de préférence à des lacets pour une transmission plus rapide des efforts de serrage et un serrage plus efficace et plus rapide.Polyamide cables will be used in preference to laces for faster transmission of the tightening forces and a more efficient and faster tightening.
