Description

La présente invention a pour objet un passant/bloqueur pour lacet ou similaire destiné plus particulièrement au laçage d'une chaussure. The present invention relates to a passing / blocker for lace or similar particularly intended for lacing a shoe.

Une chaussure est traditionnellement constituée d'une semelle et d'une tige munie d'une ouverture pour le passage du pied et comportant de part et d'autre de cette ouverture un ensemble de passants pour un ou plusieurs lacets destinés à permettre la fermeture de cette ouverture lorsqu'une traction est exercée sur ceux-ci. A shoe is traditionally composed of a sole and a shaft with an opening for the passage of the foot and comprising on either side of this opening a set of loops on one or more laces for allowing the closing this opening when traction is exerted thereon.

Ces passants sont généralement constitués par des crochets, mais ces crochets ne retiennent pas le lacet lorsque celui-ci est desserré, ou des boucles au travers desquelles passent les lacets, ceux-ci passant alternativement au-dessus et en-dessous du plan de chaque boucle. These loops are generally constituted by hooks, but these hooks do not retain the shoelace when the latter is loosened, or loops through which pass the laces, the latter passing alternately above and below the plane of each loop.

Un problème majeur posé par tous les systèmes de passants connus est le frottement élevé se produisant entre le lacet et son passant, de sorte que la simple traction sur les extrémités libres du lacet ne suffit pas à obtenir un serrage efficace sur toute la longueur du laçage et qu'il faut exercer une traction sur chaque brin de lacet compris entre deux passants pour obtenir un serrage efficace et homogène sur toute la zone de laçage, y compris en bout de pied. A major problem with all known passers systems is the high friction occurring between the lace and the way, so that the simple traction on the free ends of the lace is not sufficient to achieve effective clamping on the entire length of lacing and must exert a traction on each lace strand between two loops to obtain an efficient and homogeneous clamping over the entire lacing zone, including toe.

Ce problème est particulièrement crucial pour les chaussures en matériau relativement rigide, par exemple les chaussures de montagne en cuir épais ou les chaussures de patinage, présentant une coque plastique relativement rigide, pour lesquelles un serrage efficace est recherché jusqu'en bout de pied. This problem is especially crucial for shoes relatively rigid material, such as thick leather hiking boots or skating boots, having a relatively rigid plastic shell, for which effective clamping is searched until toe.

En effet, ce problème de frottement est encore accru par la longueur de la zone de laçage nécessaire pour aller jusqu'en bout de pied. Indeed, the friction problem is exacerbated by the length of the lacing zone needed to go up toe.

Par ailleurs, le frottement ou mauvais coulissement du lacet est dans une certaine mesure nécessaire car l'effet de freinage qui en résulte sert également d'anti-retour facilitant le serrage, et notamment la formation de la boucle ou noeud final. Furthermore, the friction sliding of the lace or bad is to some extent necessary for the braking effect resulting also serves as a nonreturn facilitating the clamping, and in particular the formation of the loop or endpoint.

Pour remédier à ce problème, il est connu d'utiliser des coinceurs ou des bloqueurs de lacets distincts des passants qui sont soit fixés sur le bord de la tige, soit montés coulissants sur le lacet. To remedy this problem, it is known to use jammers or blockers separate laces passersby that are either attached to the edge of the upper or slidably mounted on the lace. Dans ce dernier cas, ils sont encombrants et pas forcément faciles à manipuler du fait de leur mobilité. In the latter case, they are bulky and not always easy to handle because of their mobility.

Par le WO 96/24269 (US.A.5852857) est connu un système de passant/bloqueur pour lacet constitué d'un anneau mobile par rapport à un corps qui, selon la position qu'il occupe par rapport au corps, permet le coulissement d'un lacet ou au contraire sert de bloqueur dudit lacet. From WO 96/24269 (US.A.5852857) is known a system for passing / blocking for yaw consists of a movable ring with respect to a body which, in the position it occupies relative to the body, allows the sliding of a lace or on the contrary serves blocker said lace.

Un tel passant/bloqueur présente certes des avantages mais également des inconvénients, et notamment une structure multipièces et multimatériaux coûteuse. Such passing / blocker certainly has advantages but also disadvantages, including an expensive multi-room and multi-material structure. Par ailleurs, le rendement d'un tel système dans son mode de fonctionnement en tant que passant n'est pas optimum puisque le lacet passe alternativement de part et d'autre du plan de laçage d'où des frottements parasites. Moreover, the efficiency of such a system in its operation as passing is not optimal since the lace passes alternately on either side of the lacing plane where parasitic friction.

Par ailleurs, l'efficacité d'un tel bloqueur dépend énormément du diamètre du lacet à coincer entre le corps et son anneau mobile. Furthermore, the effectiveness of such a blocker is highly dependent on the diameter of the lace trapped between the body and movable ring.

Le document US 4,290,173 se rapporte à un dispositif de blocage en tension d'un lacet ayant un canal de glissement pour mettre en tension le lacet et un espace de forme tronconique pour effectuer le blocage du lacet. US 4,290,173 relates to a tensioning device for locking a lace having a sliding channel for tensioning lace and a frustoconical space to perform the locking of the lace. Le canal et l'espace s'inscrivent dans des plans angulairement distincts ; The channel and the space register in angularly distinct planes; ce qui augmente le risque de coincement du lacet lors de la mise en tension et favorise la perte de rendement du lacet. which increases the risk of jamming lace during tensioning and promotes the loss of yaw performance.

Le document US 3,296,669 concerne un dispositif de blocage d'un lacet destiné à maintenir en tension le lacet sans devoir effectuer le noeud du lacet. US 3,296,669 relates to a locking device of a lace for maintaining tension in the lace without having to make the yaw node. Un tel dispositif n'a pas pour fonction de servir de passant au lacet et sert simplement de bloqueur remplaçant le noeud de lacet. Such a device does not function to serve passing lace and simply serves blocker replacing the shoelace knot.

Le document US 5,467,511 concerne un système de laçage rapide de lacet comprenant un guide et une fente espacée du guide et positionnée dans la même direction que le guide. US 5,467,511 relates to a rapid yaw lacing system comprising a guide and a spaced guide slot and positioned in the same direction as the guide. Un tel dispositif a pour inconvénient de favoriser la perte en tension du à l'agencement particulier du guide par rapport à la fente de blocage. Such a device has the drawback of promoting the voltage loss due to the particular arrangement of the guide relative to the locking slit.

Le but de la présente invention est de remédier aux inconvénients de l'état de la technique et de fournir un passant/bloqueur amélioré, qui soit d'un coût et d'un encombrement minimum, et qui permette de concilier les deux exigences antagonistes d'améliorer le rendement du serrage, et d'offrir une fonction coinceur en fin de serrage. The purpose of the present invention is to overcome the disadvantages of the prior art and provide a passing / improved blocker, which is a cost and a small footprint, and that reconciles the two opposing requirements improve the tightening efficiency, and provide a cam function at the end of tightening.

Le passant/bloqueur selon l'invention doit également être ergonomique et facile à utiliser. The passing / block according to the invention must also be ergonomic and easy to use. Ce but est atteint dans le dispositif de guidage et blocage d'un lacet selon la revendication 1 pour une chaussure selon la revendication 13. This object is achieved in the guiding and locking of a lace according to claim 1 for a shoe according to claim 13.

  • une partie de coulissement définissant un chemin de passage, pour le guidage d'un lacet coulissant au travers du chemin, ladite partie étant orientée dans une direction de guidage correspondant sensiblement à la direction de la force de traction exercée pour mettre le lacet sous tension lors du serrage ; a sliding portion defining a passageway for guiding a drawstring through the path, said portion being oriented in a guiding direction substantially corresponding to the direction of the pulling force to put the lace on when tightening;
  • une partie de coincement arrangée le long d'une direction de blocage pour maintenir le lacet dans une position de blocage ; a wedge portion arranged along a locking direction for holding the lace in a locking position; la partie de coincement étant arrangée en continuité de la partie de coulissement ; the clamping portion being arranged in continuity of the sliding portion;
  • caractérisé en ce que, characterized in that
    la direction de blocage est orientée dans un même plan que la direction de guidage, le plan correspondant au passage continu du lacet dans les deux parties, the locking direction is oriented in the same plane as the guide direction, the plane corresponding to the continuous passage of the lace in both parts,
    et en ce que, and in that,
    la direction de blocage forme un angle non nul par rapport à la direction de guidage pour exercer le blocage du lacet dans la partie de coincement. the locking direction forms a non-zero angle with respect to the guide direction to carry the lace locking in the clamping portion.

    Le fait que la partie de coincement se trouve en continuité avec la partie de glissement permet d'obtenir un effet de coincement immédiat à l'issue de l'opération de serrage proprement, -c'est-à-dire celle où un effort de traction est exercé sur les brins du lacet, dès que l'on ramène lesdits brins transversalement à la direction de traction pour former le noeud. The fact that the clamping portion is in continuity with the sliding part provides an immediate wedging effect at the end of the tightening process itself, -that is to say that where an effort traction is exerted on the strands of the lace, as soon as it is brought back said strands transversely to the pulling direction to form the knot.

    Selon un mode de réalisation préféré, la partie de coulissement et la partie de coincement sont sensiblement coplanaires, et le plan médian de la partie de coulissement et la partie de coincement est sensiblement coplanaire au plan de laçage. According to a preferred embodiment, the sliding portion and the wedge portion are substantially coplanar, and the median plane of the gliding part and the wedging part is substantially coplanar with the plane of lacing. De ce fait un rendement optimal du serrage est garanti puisque le lacet reste toujours sensiblement dans le même plan de laçage et que les frottements sont ainsi réduits au maximum. Thus optimum tightening efficiency is guaranteed because the lace is always substantially the same lacing plane and friction are reduced to the maximum.

    D'autres modes particuliers de réalisation selon l'invention sont indiqués dans les revendications 2-12,14,15. Other particular embodiments of the invention are indicated in the claims 2-12,14,15.

    De toute façon, 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 au dessin schématique annexé en illustrant à titre d'exemples non limitatifs quelques modes de réalisation préférés, et dans lequel : Anyway, the invention will be better understood and other characteristics thereof will become apparent with the following description with reference to the accompanying drawings illustrating by way of non-limiting examples of some ways preferred embodiment, and wherein:

    • la figure 1 est une vue de dessus d'une chaussure illustrant le fonctionnement du passant au cours de l'opération de traction sur le lacet, Figure 1 is a top view of a shoe illustrating the operation of passing during the pulling operation on the lace,
    • la figure 2 est une vue similaire à la figure 1 illustrant le fonctionnement du passant au cours de l'opération de coincement du lacet, Figure 2 is a view similar to Figure 1 illustrating the operation of passing over the lace wedging operation,
    • la figure 3 est une vue en coupe selon III-III de la figure 4, Figure 3 is a sectional view along III-III of Figure 4,

    • la figure 6 est une vue similaire à la figure 5 d'un passant/bloqueur selon un second mode de réalisation. Figure 6 is a view similar to Figure 5 of a Guide / block according to a second embodiment.

    Les figures 1 et 2 illustrent le fonctionnement d'un passant/bloqueur 10 selon l'invention disposé à l'extrémité supérieure d'une zone de laçage 9 d'une chaussure 1, laquelle zone de laçage 9 comporte une pluralité de passant 8 disposés de part et d'autre d'une ouverture 6 de la chaussure, et à travers lesquels passe un lacet 7. Figures 1 and 2 illustrate the operation of a through / hold circuit 10 according to the invention arranged at the upper end of a lacing zone 9 of a shoe 1 which lacing zone 9 has a plurality of through 8 arranged on either side of an opening 6 of the shoe, and through which pass a loop 7.

    Comme le montrent plus particulièrement les figures 3 à 5, le passant/bloqueur 10 est constitué tout d'abord d'une patte 11 de fixation à la chaussure permettant aussi bien un liaison par couture que par rivet. As shown more particularly in Figures 3 to 5, the through / hold circuit 10 consists firstly of a lug 11 for attachment to the shoe allowing both a bonding seam by rivet. Bien entendu tout autre mode de fixation à la chaussure peut également être prévu. Of course any other method of attachment to the shoe can also be provided.

    La partie fonctionnelle du passant/bloqueur 10 est constituée essentiellement de deux parties, à savoir une première partie 20 de coulissement et une seconde partie 30 de coincement. The functional part of the through / hold circuit 10 consists essentially of two parts, namely a first part 20 of sliding and a second part 30 of jamming.

    La partie de coulissement 20 est constituée essentiellement par un logement essentiellement cylindrique dont le diamètre est légèrement supérieur à celui du lacet devant coulisser dans le passant 10, et qui définit pour ledit lacet un chemin de passage 21 orienté selon une direction "T" correspondant à la direction de traction du lacet (cf. flèches "T" sur les figures 1 et 3), et orientée sensiblement parallèlement à la direction générale de la zone de laçage 9. The sliding portion 20 is constituted essentially by a substantially cylindrical housing having a diameter slightly greater than that of the lace to slide through the loop 10, and which defines for said lace a passageway 21 oriented in a direction "T" corresponding to the yaw pulling direction ( "T" cf. arrows in figures 1 and 3), and oriented substantially parallel to the general direction of the lacing zone 9.

    Ce chemin de passage 21 est défini latéralement par une paroi externe 22 sensiblement curviligne en direction transversale, mais s'étendant sensiblement parallèlement à la direction de traction "T" en direction longitudinale, et par une paroi interne 23, c'est-à-dire située du côté de la zone de laçage, de forme sensiblement curviligne en direction longitudinale et comportant deux rayons d'entrée et de sortie respectivement 24, 25. Il est également défini en haut et en bas par deux parois respectivement 26, 27, arrondies. This passageway 21 is defined laterally by an outer wall 22 substantially curvilinear in cross direction but extending substantially parallel to the pulling direction "T" in the longitudinal direction, and by an inner wall 23, that is, say on the side of the lacing zone, a substantially arcuate shape in longitudinal direction and having two input and output beams respectively 24, 25. It is also defined in the top and bottom respectively by two walls 26, 27, rounded .

    Le chemin de passage 21 ainsi défini permet, par ses parties arrondies et son orientation générale, un coulissement optimum du lacet. The passageway 21 thus defined makes it possible, by its rounded parts and its overall orientation, an optimum sliding of the lace. Par ailleurs, ce chemin de passage 21 définit un trajet du lacet, dont le plan médian est toujours situé dans le même plan "P", qui est celui du laçage, sans passage d'un côté et de l'autre de ce plan. Furthermore, this passageway 21 defines an estimated yaw whose median plane is always located in the same plane "P", which is that of the lacing, without passage on one side and the other of this plane. Il en résulte un glissement encore amélioré du lacet, et donc un rendement optimum du serrage du fait de la suppression des frottements parasite, liés au passage du lacet de part et d'autre du plan de laçage, typiques des systèmes de passants classiques. This results in a further improved sliding of the lace, and thus an optimum tightening efficiency due to the removal of parasitic friction associated with hand lace passing side of the lacing plane, typical of conventional systems passersby.

    La partie de coincement 30 est située dans le prolongement de la partie de coulissement 20, au niveau de l'extrémité de sortie de ladite partie de coulissement 20 et son plan médian est confondu avec le plan médian "P" de ladite partie de coulissement, et est orienté selon une direction "B" sensiblement perpendiculaire (c'est-à-dire faisant un angle "a" compris entre sensiblement 45° et 90°) à la direction de traction "T", et correspondant à la direction de blocage. The wedge portion 30 is located in the extension of the sliding portion 20 at the outlet end of said sliding portion 20 and its median plane coincides with the median plane "P" of said sliding portion, and is oriented in a direction "B" substantially perpendicular (that is to say forming an angle "a" between substantially 45 ° and 90 °) to the pulling direction "T", and corresponding to the locking direction .

    Cette partie de coincement 30 est définie, du côté de la zone de laçage, par une paroi cylindrique 31 venant en prolongement de la paroi 25 de la partie de coulissement 20, et en haut et ne bas par deux parois sensiblement horizontales respectivement 32, 33. This part of jamming 30 is defined, on the side of the lacing zone, by a cylindrical wall 31 from an extension of the wall 25 of the sliding portion 20 and the top and bottom by two substantially horizontal walls, respectively 32, 33 .

    La partie 30 n'est pas fermée, du côté opposé à la zone de laçage, de façon à permettre le rabattement du lacet 7, à partir de sa position de coulissement représentée en trait mixtes selon la direction "T" sur la figure 3. The portion 30 is not closed, the side opposite the lacing zone, so as to allow the folding of the lace 7, from its sliding position shown in chain line in the direction "T" in Figure 3.

    Les deux parois 32 et 33 sont en retrait par rapport aux parois adjacentes 26, 27, de la partie de coulissement 20 et délimitent ainsi une section de passage d'une hauteur "h" sensiblement réduite par rapport à la hauteur "H" de la section de passage du chemin 21 (cf. figure 4). The two walls 32 and 33 are recessed relative to the adjacent walls 26, 27, the sliding portion 20 and thus define a flow section with a height "h" substantially reduced relative to the height "H" of the passage section of the path 21 (Figure 4).

    Cette réduction de la hauteur de passage permet d'obtenir un premier effet de coincement sur le lacet 7. This reduction in clearance height provides a first wedging effect on the lace 7.

    De préférence, le rapport "h/H" est compris entre environ 0,3 et 1. Preferably, the ratio "h / H" is between about 0.3 and 1.

    Pour améliorer l'effet de coincement, les parois 32, 33, sont également munies de dents 34. To improve the wedging effect, the walls 32, 33 are also provided with teeth 34.

    Ces dents sont de préférence inclinées, selon un angle "a" d'environ 45° par rapport à la direction de blocage "B" indiquée sur la figure 3. These teeth are preferably inclined at an angle "a" of approximately 45 ° with respect to the locking direction "B" shown in Figure 3.

    Ces dents pourraient également être droites et par exemple parallèles à la direction de la paroi 22. These teeth may also be straight, for example parallel to the direction of the wall 22.

    Chaque dent 34 comporte, dans le sens de la direction de blocage "B", une première partie 34a en forme de rampe ascendante et une seconde partie 34b relativement droite de façon à faciliter, par l'effet rampe, le coincement du lacet, et à retenir, par l'effet mur de leur partie droite 34b, ledit lacet en position de coincement. Each tooth 34 has, in the direction of the locking direction "B", a first portion 34a shaped ascending ramp and a second portion 34b relatively straight so as to facilitate, by virtue ramp, wedging the lace, and retaining, by the effect of their right wall portion 34b, said yaw wedging position.

    Selon un autre mode de réalisation représenté à la figure 6 et pour lequel les mêmes éléments seront désignés par des références identiques, chaque dent 34 comporte par ailleurs un profil 34c en forme de rampe allant en s'évasant du fond 31 de la partie de coincement 30 jusque vers les extrémités libres de celle-ci en formant avec la paroi 32, 33, un angle "β", compris entre environ 0 et 15°, et de préférence environ 6°, de façon à procurer un effet de coincement supplémentaire. According to another embodiment shown in Figure 6 and for which the same elements will be designated by identical references, each tooth 34 further comprises a shaped profile 34c ramp which widens from the bottom 31 of the clamping portion 30 up to the free ends thereof forming with the wall 32, 33, an angle "β" between about 0 and 15 ° and preferably about 6 °, so as to provide an additional clamping effect.

    Le passant/bloqueur 10 selon l'invention est d'une utilisation très simple et facile. The passing / hold 10 of the invention is a very simple and easy to use.

    En effet, sa partie de coulissement permet d'appliquer très facilement l'effort de tension de serrage souhaité par simple traction selon "T" sur chaque brin du lacet 7 (cf. figure 1). Indeed, its sliding portion allows to apply easily the clamping tension force desired by simple traction as "T" on each strand of the lace 7 (see Figure 1).

    Une fois la tension de serrage souhaitée obtenue, il suffit de rabattre les brins de lacet vers l'intérieur selon la direction "B", ce qui correspond exactement au mouvement nécessaire pour commencer à faire un noeud, pour coincer les brins de lacet 7 dans la partie 30 du passant/bloqueur, et donc empêcher tout desserrage intempestif. Once the desired clamping voltage obtained, simply fold the lace strands inwardly in the direction "B", which corresponds exactly to the movement necessary to start making a node for clamping the lace strands 7 in the part 30 of the through / hold, and thus prevent accidental loosening. Le noeud peut ensuite être terminé sans risque de desserrage intempestif, et donc de perte de tension, du lacet. The node can then be done without risk of accidental loosening, and thus loss of tension, yaw.

    De plus, même dans cette position (lacet bloqué dans les crans 34) on peut réajuster la tension de serrage par simple traction sur le lacet car celui-ci se déverrouille automatiquement du fait des rampes 34a et de l'angle "α" des dents 34. Moreover, even in this position (lace blocked in the notches 34) can adjust the clamping tension by simple traction on the lace because it automatically unlocks due to the ramps 34a and the angle "α" of the teeth 34.

    Par ailleurs, la réalisation du noeud est grandement facilitée puisqu'elle peut être effectuée sur des brins libérés de toute tension, du fait de l'effet de blocage obtenu. Moreover, the realization of the node is greatly facilitated since it can be performed on strands released from tension, due to the blocking effect obtained.

    On notera que ce passant/bloqueur est particulièrement simple et facile à utiliser puisque les mouvements nécessaires à l'effet de traction ou de blocage correspondent exactement à ceux qui sont naturellement effectués. Note that this passer / blocker is particularly simple and easy to use since the movements required for the pulling effect or blocking exactly match those that are naturally made.

    Notamment, le blocage n'impose pas de rabattre le lacet dans un plan inférieur comme c'est le cas dans le passant/bloqueur du WO 96/24269, (US.A.5852857) et est donc beaucoup plus pratique d'emploi. In particular, the blocking does not impose fold the lace in a lower plane as is the case in the passing / blocking of WO 96/24269, (US.A.5852857) and is therefore much more convenient to use.

    On notera aussi la simplicité de déverrouillage réalisé lui aussi par l'effet de l'écartement naturel des lacets. Note also the unlocking simplicity achieved also by the effect of natural separation of the laces.

    Enfin, un tel passant/bloqueur peut être réalisé très facilement puisqu'il ne comporte pas de pièce mobile de façon monobloc par moulage d'un matériau plastique approprié, et est donc peu coûteux à réaliser. Finally, such a through / hold circuit can be achieved very easily since it has no moving parts in one piece by molding a suitable plastic material and is therefore inexpensive to produce.
