Description

La présente invention concerne une chaussure avec un passant bloqueur de cordon c'est à dire un dispositif permettant de recevoir un cordon et de bloquer ce dernier dans une certaine position pour maintenir un serrage par exemple.The present invention relates to a shoe with a cord holder, ie a device for receiving a cord and blocking the cord in a certain position to maintain a tightening for example.

Le document CH443970 décrit une solution pour serrer et fermer une chaussure qui repose sur un lacet traversant plusieurs passants en forme de boucle fermée pour permettre le rapprochement de deux parties de chaussure séparées par une échancrure afin d'obtenir le serrage de la chaussure. Cette solution comprend de plus un dernier passant avec un élément de blocage du lacet dans la partie haute de la chaussure pour permettre le maintien du serrage effectué. Ce moyen de blocage peut être manuellement déverrouillé pour l'ouverture de la chaussure. L'inconvénient principal de cette solution vient du fait que comme le serrage du lacet se fait manuellement par une traction des deux brins de lacet sortant du dernier passant bloqueur dans la partie haute de la chaussure, une longueur minimale importante du lacet est nécessaire pour permettre cette manipulation. De plus, comme le lacet a une longueur permettant une amplitude de serrage assez importante, ces brins dépassant la zone de serrage vers le haut de la chaussure peuvent avoir une longueur importante après le serrage et représenter un encombrement et un inconvénient important puisqu'ils risquent ensuite de s'accrocher accidentellement lors de la pratique d'un sport par exemple. De plus, cette solution n'est pas conviviale puisque l'utilisateur doit inventer un moyen d'accrocher ces brins dépassant excessivement dans la partie haute de la chaussure pour limiter les risques mentionnés précédemment, ce qui a aussi souvent un effet nuisible à l'esthétique d'ensemble de la chaussure. Enfin, cette solution nécessite une intervention manuelle directement sur le passant bloqueur au moins pour le déverrouiller, ce qui n'est pas convivial.The document CH443970 describes a solution for tightening and closing a shoe that rests on a lace through several passers-shaped closed loop to allow the bringing together of two shoe parts separated by a notch to obtain the tightening of the shoe. This solution further comprises a last pass with a lace locking element in the upper part of the shoe to allow the maintenance of the tightening performed. This locking means can be manually unlocked for the opening of the shoe. The main disadvantage of this solution comes from the fact that as the tightening of the lace is done manually by pulling the two yarn strands coming out of the last blocker loop in the upper part of the boot, a minimum length of the lace is necessary to allow this manipulation. In addition, as the lace has a length allowing a fairly large clamping amplitude, these strands exceeding the clamping zone towards the top of the boot can have a significant length after tightening and represent a bulk and a significant disadvantage since they risk then accidentally hang on during the practice of a sport for example. In addition, this solution is not user friendly since the user must invent a way to hang these strands protruding excessively in the upper part of the shoe to limit the risks mentioned above, which also often has a detrimental effect on the overall aesthetics of the shoe. Finally, this solution requires manual intervention directly on the blocking pass at least to unlock it, which is not user friendly.

Une autre solution de l'art antérieur est décrite dans le document FR2473280 qui repose sur un lacet spécifique possédant des crans espacés sur sa longueur. Un inconvénient majeur de cette solution est de nécessiter ce lacet particulier.Another solution of the prior art is described in the document FR2473280 which rests on a specific lace having notches spaced along its length. A major disadvantage of this solution is to require this particular lace.

Un objet général de la présente invention consiste en une solution pour bloquer un cordon de serrage d'un vêtement qui ne comprend pas les inconvénients précédents.A general object of the present invention is a solution for locking a drawstring of a garment that does not include the foregoing disadvantages.

Plus précisément, un premier objet de la présente invention consiste en une solution de guidage et blocage d'un cordon qui ne nécessite pas une longueur importante du cordon induisant la présence de brins gênants hors de la zone de serrage.More specifically, a first object of the present invention is a solution for guiding and locking a bead which does not require a large length of the bead inducing the presence of troublesome strands outside the clamping zone.

Un second objet de la présente invention consiste en une solution de guidage et serrage d'un cordon conviviale.A second object of the present invention is a solution for guiding and tightening a cord friendly.

Un troisième objet de la présente invention consiste en une solution de guidage et serrage fonctionnant avec tout cordon classique comme un lacet lisse et uniforme de chaussure.A third object of the present invention is a guiding and clamping solution operating with any conventional cord such as a smooth and uniform shoe lace.

L'invention repose sur une chaussure avec un passant bloqueur de cordon selon la revendication 1.The invention is based on a shoe with a drawstring fastener according to claim 1.

L'élément de blocage peut être monté en rotation autour d'un axe sur l'embase avec un moyen de rappel qui tend à le maintenir dans la première position de blocage. L'élément de blocage peut être apte à une rotation autour de cet axe par un effort ayant une composante verticale exercé par une traction du cordon dans une direction perpendiculaire à l'embase du passant bloqueur de manière à permettre la libération totale et l'insertion du cordon.The locking element can be rotatably mounted about an axis on the base with a biasing means which tends to maintain it in the first locking position. The blocking member may be rotatable about this axis by a force having a vertical component exerted by pulling the cord in a direction perpendicular to the base of the blocking passer so as to allow complete release and insertion. cord.

Selon une variante avantageuse, l'élément de blocage présente une surface supérieure arrondie au niveau de sa proximité avec la partie supérieure de l'élément passant, qui présente aussi une surface supérieure arrondie, afin de faciliter la libération totale et la réinsertion du cordon.According to an advantageous variant, the locking element has a rounded upper surface at its proximity to the upper part of the passing element, which also has a rounded upper surface, in order to facilitate the total release and re-insertion of the bead.

L'élément de blocage peut avoir une surface de blocage comprenant des dents pour coopérer avec un cordon ou lacet lisse classique. De plus, cette surface de blocage peut former une came favorisant le glissement du cordon dans le sens du serrage uniquement.The locking member may have a blocking surface including teeth for cooperating with a conventional smooth cord or lace. In addition, this blocking surface can form a cam promoting the sliding of the cord in the tightening direction only.

Selon une première variante, l'élément passant peut comprendre une base cylindrique formant une surface de glissement lisse et un chapeau positionné sur la base cylindrique qui empêche l'échappement du cordon verticalement à l'embase dans une configuration de blocage.According to a first variant, the passing element may comprise a cylindrical base forming a smooth sliding surface and a cap positioned on the cylindrical base which prevents the escape of the cord vertically to the base in a locking configuration.

Selon une seconde variante, l'élément passant et l'embase appartiennent à la même pièce, l'élément passant ayant une forme de gouttière délimitant une partie creuse courbée et de surface lisse pour le positionnement et le glissement du cordon et un rebord.According to a second variant, the passing element and the base belong to the same part, the passing element having a gutter shape defining a curved hollow portion and smooth surface for the positioning and sliding of the cord and a flange.

Selon une variante, l'élément de blocage est monté en rotation sur l'embase et comprend une ouverture dans laquelle est positionné un ressort de rappel dont une première extrémité est en butée sur une protubérance de l'embase et une seconde extrémité est en appui sur l'élément de blocage.According to a variant, the locking element is rotatably mounted on the base and comprises an opening in which is positioned a return spring whose one end is in abutment on a protuberance of the base and a second end is in abutment. on the blocking element.

Enfin, l'invention porte aussi sur une chaussure de sport comprenant un lacet lisse et un passant bloqueur de cordon tel que défini précédemment placé dans la partie supérieure de la zone de laçage de la chaussure.Finally, the invention also relates to a sports shoe comprising a smooth lace and a cord holder as defined above placed in the upper part of the lacing zone of the shoe.

Le lacet d'une telle chaussure peut avoir une longueur telle que les brins extrêmes dépassent de moins de 10 centimètres au-delà du passant bloqueur dans la position de repos de la chaussure dans laquelle le lacet est tendu.The lace of such a shoe may have a length such that the extreme strands exceed less than 10 centimeters beyond the blocking passer in the rest position of the shoe in which the lace is stretched.

Ces objets, caractéristiques et avantages de la présente invention seront exposés en détail dans la description suivante de modes d'exécution particuliers faits à titre non-limitatif en relation avec les figures jointes parmi lesquelles :

These objects, features and advantages of the present invention will be set forth in detail in the following description of particular embodiments given in a non-limiting manner in relation to the appended figures among which:
  • The figure 1 is a perspective view of a cord locker according to a first embodiment of the invention;

Le bloqueur de cordon du premier mode d'exécution de l'invention, illustré sur les figures 1 et 2, comprend un premier élément 1 en forme de champignon dont la fonction est une fonction de passant de cordon, un second élément 2 coopérant avec ce premier élément et dont la fonction est plus précisément le blocage du cordon, ces deux éléments 1, 2 étant montés sur une embase 3 destinée à une fixation sur une chaussure.The cord blocker of the first embodiment of the invention, illustrated on the Figures 1 and 2 , comprises a first element 1 in the form of a mushroom whose function is a cord loop function, a second element 2 cooperating with this first element and whose function is more precisely the locking of the cord, these two elements 1, 2 being mounted on a base 3 for attachment to a shoe.

Le premier élément passant 1 a une base cylindrique 4 destinée à être au moins partiellement parcourue par un cordon, surmontée par un chapeau 6 qui assure un maintien du cordon contre cette base 4 et sur l'embase 3, évitant qu'il ne s'en échappe trop facilement par le haut en cas de cordon non tendu par exemple. La base cylindrique 4 du passant 1 a une surface cylindrique lisse qui favorise le glissement du cordon et se trouve proche d'une partie dentée 8 du second élément de blocage 2, ces deux éléments 1, 2 délimitant ainsi un espace restreint 5 pour le passage du cordon. L'élément de blocage 2 est monté en rotation autour d'un axe 7 vertical à l'embase 3, un ressort non représenté agissant sur cet élément dans le sens de rotation vers le premier élément passant 1, jusqu'à une position de butée correspondant à une configuration de blocage du passant bloqueur de cordon comme illustrée sur la figure 1.The first member passing 1 has a cylindrical base 4 intended to be at least partially traversed by a cord, surmounted by a cap 6 which ensures a maintenance of the cord against this base 4 and on the base 3, avoiding that it escapes too easily from above in case of unstretched cord for example. The cylindrical base 4 of the passage 1 has a smooth cylindrical surface which promotes the sliding of the bead and is close to a toothed portion 8 of the second locking element 2, these two elements 1, 2 thus delimiting a restricted space 5 for the passage cord. The locking element 2 is rotatably mounted about a vertical axis 7 at the base 3, a not shown spring acting on this element in the direction of rotation towards the first passing element 1, to a stop position corresponding to a locking configuration of the cord blocking passer as illustrated on the figure 1 .

Dans la configuration normale de butée de l'élément de blocage 2, l'espace 5 compris entre les dents de la surface 8 de l'élément de blocage 2 et la base cylindrique 4 du passant a une dimension légèrement inférieure au diamètre du cordon destiné à coopérer avec ce passant bloqueur afin d'assurer la pression des dents contre le cordon et obtenir le maintien du cordon. Une traction du cordon dans le sens du serrage va permettre d'exercer une force, illustrée par la flèche F sur la figure 2, s'opposant au ressort de rappel de l'élément de blocage 2 et entraînant sa légère rotation pour permettre le glissement du cordon dans l'espace 5 dans le sens de la flèche F, induisant le serrage de la chaussure. La forme de la surface 8 et de ses dents est adaptée pour faciliter le glissement du cordon dans le sens du serrage en entraînant une légère rotation de l'élément bloqueur 2 autour de son axe 7 afin d'autoriser et accompagner ce mouvement contre l'axe 4 qui remplit sa fonction de guidage et passant. Pour cela, la surface extrême 8 de l'élément bloqueur forme une came courbée dont les dents sont de plus en plus éloignées de l'axe de rotation 7 quand on s'éloigne dans le sens de la flèche F.In the normal abutment configuration of the locking element 2, the space 5 between the teeth of the surface 8 of the locking element 2 and the cylindrical base 4 of the passer has a dimension slightly smaller than the diameter of the cord for to cooperate with this passing blocker to ensure the pressure of the teeth against the cord and obtain the maintenance of the cord. A pull of the cord in the tightening direction will allow to exert a force, illustrated by the arrow F on the figure 2 , opposing the return spring of the locking element 2 and causing its slight rotation to allow the sliding of the cord in the space 5 in the direction of the arrow F, inducing tightening of the shoe. The shape of the surface 8 and its teeth is adapted to facilitate the sliding of the cord in the direction of tightening by causing a slight rotation of the blocking element 2 about its axis 7 to allow and accompany this movement against the axis 4 which fulfills its guiding and passing function. For this, the end surface 8 of the blocking element forms a curved cam whose teeth are further and further away from the axis of rotation 7 when one moves away in the direction of arrow F.

Au contraire, toute traction du cordon dans le sens opposé au serrage tend à entraîner, sous l'effet combiné des dents et de la forme de la surface 8 de l'élément de blocage 2 décrite ci-dessus, la rotation de cet élément 2 vers sa position de butée contre le passant 1, rotation assistée par la force du ressort de rappel. Quand la butée est atteinte, cette rotation est impossible et toute traction dans cette direction opposée à la flèche F entraîne une plus forte pénétration des dents de l'élément de blocage 2 dans le cordon et le maintien de ce dernier dans sa position. Ainsi, tout serrage d'un cordon est donc bien maintenu par le dispositif bloqueur de cordon qui n'autorise qu'une seule direction de glissement du cordon.On the contrary, any traction of the cord in the opposite direction to the tightening tends to cause, under the combined effect of the teeth and the shape of the surface 8 of the locking element 2 described above, the rotation of this element 2 towards its stop position against the passer 1, rotation assisted by the force of the return spring. When the stop is reached, this rotation is impossible and any traction in this direction opposite the arrow F causes a greater penetration of the teeth of the locking element 2 in the bead and the maintenance of the latter in its position. Thus, any tightening of a cord is well maintained by the cord lock device which allows only one direction of sliding of the cord.

Selon la caractéristique principale de l'invention, le passant bloqueur permet de plus la libération totale du cordon. Pour cela, une traction du cordon dans une direction s'éloignant verticalement de l'embase 3 du dispositif passant bloqueur va entraîner le cordon vers le rebord 6 de la partie haute du passant 1 puis son glissement entre les deux éléments 1, 2, favorisé par une forme courbée de l'élément 6 d'une part et d'autre part par la partie supérieure 9 arrondie disposée au niveau de l'extrémité de l'élément 2 à proximité du chapeau 6 de l'élément passant 1. Ces deux formes courbées forment un entonnoir qui favorise le glissement du cordon. L'effort de traction exercé sur le cordon crée une force ayant une composante perpendiculaire à l'embase 3 et va entraîner un écartement de l'élément de blocage 2 par sa rotation autour de l'axe 7, s'opposant à la force de rappel exercée par le ressort de rappel, vers une position telle qu'illustrée en figure 2 dans laquelle le cordon non représenté va pouvoir échapper totalement au dispositif passant bloqueur par l'espace créé dans la partie supérieure de ce dispositif, entre les parties supérieures 6 et 9 des éléments 1 et 2. En remarque, la traction sur le cordon dans cette manoeuvre de libération comporte aussi une composante dans le sens du serrage qui participe aussi à la rotation de l'élément de blocage 2.According to the main characteristic of the invention, the blocking passer also allows the total release of the bead. For this, pulling the cord in a direction away vertically from the base 3 of the blocking passing device will cause the cord to the flange 6 of the upper part of the passer 1 and its sliding between the two elements 1, 2, favored by a curved shape of the element 6 on the one hand and secondly by the rounded upper portion 9 disposed at the end of the element 2 near the cap 6 of the passing element 1. These two Curved shapes form a funnel that promotes the sliding of the cord. The tensile force exerted on the cord creates a force having a component perpendicular to the base 3 and will cause a spacing of the locking element 2 by its rotation about the axis 7, opposing the force of return by the return spring to a position as illustrated in FIG. figure 2 in which the cord not shown will be able to completely escape the blocking device by the space created in the upper part of this device, between the upper parts 6 and 9 of the elements 1 and 2. Note, the pull on the cord in this release maneuver also comprises a component in the tightening direction which also participates in the rotation of the locking element 2.

Inversement, il est possible de réintroduire le cordon dans le dispositif passant bloqueur, par une manoeuvre relativement inverse. Pour cela, il suffit de placer le cordon au-dessus du dispositif dans la zone frontière entre les deux éléments 1, 2 et d'exercer une traction sur ce cordon avec une composante verticale vers l'embase 3 du dispositif. Un tel effort va permettre le glissement du cordon sur les parties arrondies au sommet des éléments 1, 2, l'écartement de l'élément de blocage 2 de sa position de butée puis l'abaissement du cordon dans l'espace 5 contre la base 4 de l'élément passant 1, l'élément de blocage 2 reprenant sa position normale de butée et de blocage sous l'effet de son ressort de rappel. En remarque, cette phase de réinsertion du cordon comprend avantageusement une traction du cordon avec une composante dans le sens du serrage F pour favoriser la rotation de l'élément de blocage 2.Conversely, it is possible to reintroduce the cord into the device passing blocker, by a relatively inverse maneuver. For this, simply place the cord above the device in the border area between the two elements 1, 2 and exert traction on the cord with a vertical component to the base 3 of the device. Such a force will allow the sliding of the cord on the rounded portions at the top of the elements 1, 2, the spacing of the locking element 2 from its abutment position and the lowering of the cord in the space 5 against the base 4 of the passing element 1, the locking element 2 resuming its normal position of abutment and locking under the effect of its return spring. As a reminder, this reinsertion phase of the cord advantageously comprises pulling the cord with a component in the tightening direction F to promote the rotation of the locking element 2.

Ce passant bloqueur présente donc l'avantage de permettre la libération totale du cordon et sa réinsertion de manière conviviale et facile, sans nécessiter de manipulation du dispositif lui-même, mais seulement par une traction sur les extrémités du cordon. Cet avantage du passant bloqueur sera détaillé lors de la description de son application pour une chaussure de sport, en référence aux figures 6 et 7.This blocking loop therefore has the advantage of allowing the complete release of the cord and its reinsertion in a user-friendly and easy manner, without requiring manipulation of the device itself, but only by pulling on the ends of the cord. This advantage of the blocking passer will be detailed when describing its application for a sports shoe, with reference to the Figures 6 and 7 .

Un second mode d'exécution du passant bloqueur de cordon est illustré sur les figures 3 à 5, dans lequel l'embase 13 et le passant 11 représentent une seule pièce sur laquelle vient se monter un élément de blocage de cordon 12. L'élément passant 11 a la forme d'une gouttière arrondie comprenant une partie creuse lisse et courbée 14 dans laquelle se loge un cordon et un rebord supérieur 16 pour le maintenir dans sa position. L'embase 13 comprend un axe 17 sur lequel peut coopérer une ouverture 22 de l'élément de blocage 12 pour son montage en rotation sur cette embase autour de cet axe 17. Cet élément de blocage 12 comprend de plus une seconde ouverture 21 dans laquelle se loge un ressort de compression 19 dont une première extrémité est en butée sur une protubérance 20 de l'embase 13, positionnée dans l'ouverture 21 de l'élément de blocage 12, alors que sa seconde extrémité est en appui sur cet élément de blocage 12. Ce ressort 19 agit ainsi comme un ressort de rappel qui tend à maintenir l'élément de blocage dans une configuration de blocage dans laquelle sa surface dentée 18 se trouve proche de la partie creuse 14 du passant 11, à une distance légèrement inférieure au diamètre du cordon à bloquer, délimitant ainsi un espace 15 dans lequel le cordon est apte à se déplacer dans le sens du serrage. L'embase 13 du dispositif est apte à une fixation sur un vêtement ou une chaussure par un rivet traversant l'ouverture 22 et l'ouverture centrale de l'axe 17 du dispositif.A second embodiment of the cordon-on loop is illustrated on the Figures 3 to 5 , in which the base 13 and the passage 11 represent a single piece on which is mounted a cord locking element 12. The passing element 11 has the shape of a rounded gutter comprising a hollow portion smooth and curved 14 in which lodges a cord and an upper rim 16 to maintain it in its position. The base 13 comprises an axis 17 on which can cooperate an opening 22 of the locking element 12 for its rotational mounting on this base around this axis 17. This locking element 12 further comprises a second opening 21 in which a compression spring 19 is housed, one end of which is in abutment with a protuberance 20 of the base 13, positioned in the opening 21 of the locking element 12, while its second end bears against this element of Blocking 12. This spring 19 thus acts as a return spring which tends to maintain the locking element in a locking configuration in which its toothed surface 18 is close to the hollow portion 14 of the passer 11, at a slightly smaller distance. the diameter of the cord to be blocked, thereby defining a space 15 in which the cord is able to move in the direction of tightening. The base 13 of the device is suitable for attachment to a garment or shoe by a rivet through the opening 22 and the central opening of the axis 17 of the device.

Le fonctionnement de ce cordon bloqueur est sensiblement le même que celui du premier mode d'exécution décrit précédemment. L'élément de blocage 12 comprend une surface arrondie 29 au niveau de la partie supérieure de la surface dentée 18, qui favorise le glissement du cordon lors de ses phases de libération et de réinsertion. De même, la gouttière 11 présente une extrémité courbée pour favoriser à la fois la libération et l'insertion d'un cordon.The operation of this blocking cord is substantially the same as that of the first embodiment described above. The locking element 12 comprises a rounded surface 29 at the upper part of the toothed surface 18, which promotes the sliding of the cord during its release and re-insertion phases. Similarly, the channel 11 has a curved end to promote both the release and the insertion of a cord.

Les figures 6 et 7 illustrent l'utilisation d'un passant bloqueur selon l'invention sur une chaussure de sport. Toutefois, une implémentation sur tout autre vêtement sur lequel le même problème technique se poserait serait aussi possible. La chaussure comprend une échancrure centrale 30 occupée par un lacet lisse classique 31 qui réalise des va et vient entre des passants 32 répartis de part et d'autre de l'échancrure. De chaque côté de l'échancrure, le dernier passant est un passant bloqueur 33 selon l'invention.The Figures 6 and 7 illustrate the use of a passing blocker according to the invention on a sports shoe. However, an implementation on any other garment on which the same technical problem would arise would also be possible. The shoe comprises a central notch 30 occupied by a classic smooth lace 31 which goes back and forth between passers-by 32 distributed on both sides of the notch. On each side of the notch, the last passer is a blocking passer 33 according to the invention.

La figure 6 illustre une phase de serrage de la chaussure, dans laquelle les deux brins extrêmes 34 du lacet 31 sont relativement courts et sont positionnés hors du passant bloqueur 33 pour faciliter leur prise en main sur toute une longueur au-delà du dernier passant simple 32. En remarque, le lacet 31 peut aussi être enlevé de quelques autres passants 32 pour un serrage progressif de bas en haut par exemple. Une fois le serrage effectué, l'utilisateur retient les deux brins 34 dans ses mains et les positionne dans leur logement dans les passants bloqueurs 33 qui vont alors maintenir ce serrage automatiquement. Il sera alors possible de finaliser le serrage par une nouvelle traction sur ces brins 34, le passant bloqueur 33 autorisant le glissement du lacet 31 dans le sens du serrage. La figure 7 illustre la configuration finale de la chaussure quand le lacet est serré. Cette solution permet donc un bon serrage de la chaussure même avec un lacet 31 plus court que dans l'art antérieur, dont les deux brins extrêmes 34 peuvent ne dépasser que d'une très faible longueur des passants bloqueurs 33.The figure 6 illustrates a clamping phase of the shoe, in which the two end strands 34 of the lace 31 are relatively short and are positioned outside the blocker 33 to facilitate their grip over a whole length beyond the last single pass 32. In note, the lace 31 can also be removed from some other loops 32 for a progressive tightening from bottom to top, for example. Once the tightening is done, the user holds the two strands 34 in his hands and positions them in their housing in the blocking loops 33 which will then maintain this clamping automatically. It will then be possible to finalize the tightening by a new traction on these strands 34, the blocking pass 33 authorizing the sliding of the lace 31 in the tightening direction. The figure 7 illustrates the final configuration of the shoe when the lace is tight. This solution therefore allows a good tightening of the shoe even with a lace 31 shorter than in the prior art, the two end strands 34 may only exceed a very short length of the blocking loops 33.

On définit une position de repos de la chaussure dans laquelle les deux parties 35 de la chaussure autour de l'échancrure 30 sont dans leur position naturelle, sur laquelle le lacet 31 n'exerce aucune contrainte. Grâce à la solution de l'invention, il est possible de choisir un lacet de longueur telle que dans cette position de repos de la chaussure, le lacet 31 tendu sans exercer de contrainte sur les deux parties 35 de la chaussure parcourt tous les passants 32 et présente deux brins 34 dépassant des passants bloqueurs 33 de quelques centimètres seulement, par exemple de 5 centimètres, et préférentiellement de moins de 10 centimètres.A rest position of the shoe is defined in which the two parts of the shoe around the notch 30 are in their natural position, on which the lace 31 exerts no stress. Thanks to the solution of the invention, it is possible to choose a lace length such that in this rest position of the shoe, the lace 31 stretched without exerting stress on the two parts 35 of the shoe travels all passersby 32 and has two strands 34 protruding blocking passers 33 of a few centimeters only, for example 5 centimeters, and preferably less than 10 centimeters.

Une caractéristique essentielle des passants bloqueurs selon l'invention est donc leur possibilité de libérer totalement un cordon de manière simple et conviviale. Pour cela, un espace est libéré au-dessus du cordon de manière à l'enlever ou le repositionner dans le passant bloqueur, dans une direction sensiblement perpendiculaire à l'embase du passant bloqueur.An essential characteristic of the blocking passers according to the invention is therefore their ability to completely release a cord in a simple and user-friendly manner. For this, a space is released above the cord so as to remove or reposition in the blocking pass in a direction substantially perpendicular to the base of the blocking pass.

Cette solution permet ainsi de répondre aux objets de l'invention et de présenter les avantages suivants :

  • la longueur du lacet est minimale tout en permettant un serrage efficace grâce à un élément de blocage ;
  • la solution est conviviale puisque le passant bloqueur se comporte finalement de manière similaire à un passant classique. Un utilisateur peut enlever ou positionner un lacet contre le passant bloqueur par des manipulations très similaires avec celles effectuées avec un lacet et un passant sans élément de blocage ;
  • la solution permet l'utilisation d'un lacet comprenant une poignée, voire un simple noeud, à l'extrémité de ses deux brins pour faciliter la traction manuelle, puisque le lacet n'a pas besoin d'être passé dans des boucles fermées de petites dimensions ;
  • enfin, la solution est simple, peu coûteuse, et esthétique.
This solution thus makes it possible to respond to the objects of the invention and to offer the following advantages:
  • the length of the lace is minimal while allowing effective tightening thanks to a locking element;
  • the solution is user-friendly since the blocking pass-through finally behaves similarly to a conventional pass-through. A user can remove or position a lace against the blocking by manipulations very similar to those made with a lace and a passer without blocking element;
  • the solution allows the use of a lace comprising a handle, or even a simple knot, at the end of its two strands to facilitate manual traction, since the lace does not need to be passed in closed loops of small dimensions;
  • finally, the solution is simple, inexpensive, and aesthetic.
