Domaine de l'invention Field of the invention
La présente invention concerne généralement des lacets de chaussures. En particulier, des lacets élastiques, par exemple en élastomère e.g. silicone, qui, une fois mis en place sur une chaussure, permettent à cette dernière, dans un souci de confort, de s'adapter aux variations de volume du pied de l'utilisateur, et ce sans nuire au nécessaire maintien du pied et permettent également à l'utilisateur d'enfiler et d'enlever la chaussure, de façon répétée sans dénouer les lacets.  The present invention generally relates to shoe laces. In particular, elastic laces, for example elastomer eg silicone, which, once put in place on a shoe, allow the latter, for the sake of comfort, to adapt to variations in the foot volume of the user , and without harming the necessary maintenance of the foot and also allow the user to put on and take off the shoe, repeatedly without loosening the laces.
Il peut s'agir de chaussures de sport, de chaussures orthopédiques, de chaussures de ville, etc. These may include sports shoes, orthopedic shoes, street shoes, etc.
État de la technique State of the art
Les lacets sont des cordons souples qui sont engagés dans des passants, des œillets, des boucles, des crochets... et que l'on noue pour attacher la chaussure au pied. The laces are soft cords that are engaged in loops, eyelets, buckles, hooks ... and that is tied to attach the shoe to the foot.
Classiquement, les lacets sont réalisés en tissus naturels (coton, jute ou chanvre) ou synthétiques (polyesters, polyamides, polyoléfmes : polyéthylène...), en cuir, ou en matériau élastique.  Classically, the laces are made of natural fabrics (cotton, jute or hemp) or synthetic (polyesters, polyamides, polyolefmes: polyethylene ...), leather, or elastic material.
Les extrémités des lacets comprennent une partie rigide permettant de faciliter l'enfilage dans les passants, et dans le cas des lacets en tissu, d'éviter l'effilochage desdites extrémités. The ends of the laces comprise a rigid portion to facilitate threading in the loops, and in the case of laces fabric, to avoid fraying said ends.
Du fait de leurs propriétés d'allongement élastique, les lacets élastiques visent à empêcher les serrages excessifs qui traumatisent les pieds et qui entravent la circulation sanguine. Parmi les lacets élastiques déjà commercialisés, on peut citer les lacets torsadés ou les lacets à bourrelets autobloquants. Because of their elastic elongation properties, the elastic laces aim to prevent excessive tightening which traumatize the feet and which impede the blood circulation. Among the elastic laces already marketed, mention may be made of twisted laces or laces with self-locking beads.
On connaît également des lacets en élastomère silicone disponibles à la vente sous la marque Freelace® depuis 2013.  Also known silicone elastomer laces available for sale under the trademark Freelace® since 2013.
Les élastomères silicone sont des polymères à base de silicium, de carbone, d'oxygène et d'hydrogène. Ils présentent des propriétés élastiques qui sont obtenues après réticulation et qui leur permettent de supporter de très grandes déformations avant rupture. Et ils sont également dotés d'une capacité de collisions élastiques, telles le rebondissement et l'étirement élastiques, ce qui leur permet de reprendre leur forme initiale après l'arrêt de la sollicitation.  Silicone elastomers are polymers based on silicon, carbon, oxygen and hydrogen. They have elastic properties which are obtained after crosslinking and which allow them to withstand very large deformations before rupture. And they also have a capacity for elastic collisions, such as bouncing and elastic stretching, which allows them to return to their original shape after stopping the solicitation.
Ces lacets en élastomère silicone bénéficient d'une autre propriété des silicones qui est l'anti- adhérence, de sorte qu'ils sont autobloquants. These silicone elastomer laces benefit from another property of silicones which is the anti-adhesion, so that they are self-locking.
Ils sont fabriqués de manière conventionnelle par injection-moulage ou par extrusion.  They are manufactured conventionally by injection molding or extrusion.
Ces lacets en élastomère silicone disponibles sur le marché sont néanmoins perfectibles, en particulier en ce qui concerne leur potentiel de communication et leur attractivité esthétique. De même des lacets en élastomère silicone connu pourraient être améliorés au regard de leur résistance aux déchirements. These silicone elastomer laces available on the market are nevertheless perfectible, in particular as regards their communication potential and their aesthetic attractiveness. Of even laces of known silicone elastomer could be improved with regard to their resistance to tearing.
Par ailleurs, s'agissant du laçage, les lacets sont noués sur le coup de pied, avec des boucles ou des doubles boucles. Rarement avec la double boucle mais souvent avec la simple boucle, les nœuds se défont et ce qui oblige le porteur de chaussures fermées avec ces lacets dénoués, à refaire le nouage, au risque d' abîmer ses lacets ou de chuter en marchant dessus. Moreover, with regard to lacing, the laces are knotted on the kick, with loops or double loops. Rarely with the double loop but often with the simple buckle, the knots are undone and which forces the wearer of shoes closed with these loosened laces, to redo the knotting, with the risk of damaging his laces or falling while walking on it.
Ces nœuds ne sont pas toujours esthétiques et peuvent affecter l'attractivité du design de la chaussure.  These knots are not always aesthetic and can affect the attractiveness of the design of the shoe.
Objectifs de l'invention Objectives of the invention
La présente invention vise à fournir des lacets en élastomère silicone perfectionnés en termes de marquage et/ou en terme ornemental et/ou en termes d'amélioration de la résistance au déchirement et/ou en termes d'apport de nouvelles fonctionnalités autres que les propriétés mécaniques et l'aspect extérieur.  The present invention aims to provide silicone elastomer laces improved in terms of marking and / or in ornamental terms and / or in terms of improving the tear resistance and / or in terms of providing new functionalities other than the properties. mechanical and exterior appearance.

Brève description de l'invention Brief description of the invention
La présente invention satisfait à tout ou partie de ces objectifs en proposant un nouveau lacet pour une chaussure pourvue d'un passage de lacet dont les deux bords présentent des passants, ledit lacet étant essentiellement constitué d'au moins un élastomère silicone au moins en partie réticulé et comprenant un ou plusieurs polymères silicones et des charges, et, éventuellement au moins l'un des composés suivants : catalyseur(s), réticulant(s), pigment(s), agent(s) antiadhésif(s), plastifïant(s), promoteur(s) d'adhérence, caractérisé en ce qu'il comprend, dans sa partie médiane, une zone d'identification qui forme une seule pièce avec le lacet et qui est destinée, une fois le lacet mis en place au travers des passants de la chaussure, à apparaître sur le cou-de-pied de la chaussure, entre les deux passants inférieurs situés de part et d'autre et à la base du passage de lacet. Ce lacet possède une identification visuelle marquée et séduisante sur la chaussure, ce qui met en exergue son caractère distinctif et donc son attractivité commerciale. Le lacet selon l'invention est donc doté d'un marquage en son milieu. Cet emplacement de forme par exemple rectangulaire met en avant la marque choisie pour le lacet. Son emplacement entre les deux premiers passants (e.g. œillets) et sa forme identifient parfaitement le fournisseur du lacet en le différenciant de la chaussure et en faisant ainsi un objet commercial à part entière, doté de propriétés techniques avantageuses. The present invention satisfies all or part of these objectives by proposing a new lace for a shoe provided with a lace passage whose two edges have loops, said lace consisting essentially of at least one silicone elastomer at least in part crosslinked and comprising one or more silicone polymers and fillers, and optionally at least one of the following compounds: catalyst (s), crosslinking agent (s), pigment (s), anti-adhesive agent (s), plasticizer ( s), adhesion promoter (s), characterized in that it comprises, in its median part, an identification zone which forms a single piece with the lace and which is intended, once the lace has been put into place at through passers-by of the shoe, to appear on the instep of the shoe, between the two lower passers located on either side and at the base of the lace passage. This lace has a marked and attractive visual identification on the shoe, which highlights its distinctive character and therefore its commercial attractiveness. The lace according to the invention is therefore provided with a marking in the middle. This rectangular shape location, for example, highlights the mark chosen for the lace. Its location between the two first passers (eg eyelets) and its shape perfectly identify the supplier of the lace by differentiating it from the shoe and thus making it a commercial object in its own right, with advantageous technical properties.

^ Ce lacet peut également être caractérisé par une résistance au déchirement déterminée selon la norme ASTM D 624, supérieure ou égale à, exprimée en N/mm et donnée ci- après dans un ordre croissant de préférence : 1 ; 2 ; 3 ; 4; 5 ; cette résistance au déchirement étant plus préférentiellement encore comprise entre 5 et 20 N/mm. De préférence, le lacet (1) selon l'invention est caractérisé qu'il est destiné à être bloqué par rapport à la chaussure par une plaque nommée « BlocKnot » pourvue de plusieurs passages qui retiennent le lacet par entrelacement des parties terminales libres des brins de ce dernier dans les passages et donc par grip, de préférence par cheminement des parties terminales libres des brins de ce dernier au travers des passages alternativement sur l'endroit et sur l'envers de la plaque.  This lace may also be characterized by a tear strength determined according to ASTM D 624, greater than or equal to, expressed in N / mm and given hereinafter in increasing order of preference: 1; 2; 3; 4; 5; this tear resistance being more preferably still between 5 and 20 N / mm. Preferably, the lace (1) according to the invention is characterized that it is intended to be blocked relative to the shoe by a plate called "BlocKnot" provided with several passages that retain the lace by interlacing the free end portions of the strands of the latter in the passages and therefore by grip, preferably by tracking the free end portions of the strands of the latter through the passages alternately on the place and on the back of the plate.
Avantageusement, la plaque de blocage du lacet par rapport à la chaussure présente une forme générale rectangulaire ou oblongue, et mieux encore avec une région médiane plus étroite que les régions d'extrémités. Selon d'autres variantes, cette plaque peut-être circulaire rectangulaire trapézoïdale...  Advantageously, the lace blocking plate relative to the shoe has a generally rectangular or oblong shape, and more preferably with a narrower median region than the end regions. According to other variants, this plate may be rectangular trapezoidal rectangular ...
Suivant une caractéristique remarquable de l'invention, la plaque de blocage du lacet par rapport à la chaussure présente un galbe respectant la courbure du pied. Pour ce faire le matériau constitutif de la plaque peut-être un matériau souple ou un matériau rigide préformé tel que le bois ou le PVC. Le préformage courbe en vue de côté de la plaque peut-être obtenu par usinage, cintrage, moulage. La courbure de la plaque se rapproche ainsi au mieux du galbe physiologique du pied et plus précisément du cou-de-pied. According to a remarkable feature of the invention, the yaw blocking plate relative to the shoe has a curve respecting the curvature of the foot. To do this, the material constituting the plate may be a flexible material or a preformed rigid material such as wood or PVC. The curved preforming in side view of the plate can be obtained by machining, bending, molding. The curvature of the plate is thus closer to the physiological curve of the foot and more precisely to the instep.
Sur un autre de ses aspects, l'invention concerne un ensemble de laçage comprenant une plaque nommée « BlocKnot » (30) de blocage du lacet (1) par rapport à la chaussure (2), ladite plaque étant définie ci-dessus et un lacet notamment un lacet (1) selon l'invention. In another of its aspects, the invention relates to a lacing assembly comprising a plate named "BlockKnot" (30) for locking the lace (1) relative to the shoe (2), said plate being defined above and a lace in particular a lace (1) according to the invention.
Les passages de la plaque de blocage du lacet, plus exactement de l'extrémité des brins du lacet par rapport à la chaussure, sont par exemple au nombre de 6 à 10 maximum. The passages of the yaw blocking plate, more exactly the end of the strands of the lace relative to the shoe, are for example 6 to 10 maximum.
Avantageusement, ladite plaque de blocage peut présenter des signes d'identification et/ou de décoration, de préférence sur son endroit, c'est-à-dire sa face antérieure visible. Il peut s'agir par exemple des logos ou autres graphismes sur sa surface plane. Une telle décoration peut être réalisée notamment par impression, soudage, sublimation. La plaque de blocage peut être réalisée à partir de différents matériaux, selon le rendu esthétique choisi et/ou selon l'ergonomie souhaitée. Il peut s'agir par exemple d'un matériau semi-rigide garantissant ainsi l'adaptation de la plaque à la forme du pied. Cette nouvelle solution de nouage de lacets pour les chaussures à lacets (appelée « BlocKnot ») est un substitut avantageux des nœuds traditionnels des chaussures. C'est un système de laçage sûr. Advantageously, said blocking plate may have identification and / or decoration signs, preferably on its location, that is to say its visible anterior surface. It may be for example logos or other graphics on its flat surface. Such decoration can be achieved in particular by printing, welding, sublimation. The blocking plate can be made from different materials, depending on the aesthetic rendering chosen and / or according to the desired ergonomics. It may be for example a semi-rigid material thus ensuring the adaptation of the plate to the shape of the foot. This new tying solution for lace-up shoes (called "BlocKnot") is an advantageous substitute for traditional shoe knots. It is a safe lacing system.
Cette plaque qui constitue le moyen essentiel de cette solution de laçage, est en outre destinée à embellir la chaussure par sa forme et sa finesse. Celle-ci peut être de différentes couleurs, de différentes matières afin de bien se marier avec les lacets et la chaussure. Sa face antérieure visible (endroit) peut servir de support à des logos, des visuels pour valoriser l'ensemble chaussure/laçet/plaque de blocage. Pour contribuer à la sécurité, le système de laçage selon l'invention, à savoir la plaque de blocage, intègre avantageusement des moyens de signalisation visuels, par exemple des lampes telles que des LEDs. This plate is the essential means of this lacing solution, is also intended to embellish the shoe by its shape and finesse. This one can be of different colors, different materials in order to marry well with the laces and the shoe. Its anterior face visible (place) can serve as a support for logos, visuals to enhance the shoe / laçet / blocking plate. To contribute to safety, the lacing system according to the invention, namely the locking plate, advantageously integrates visual signaling means, for example lamps such as LEDs.
Avantageusement, les trous de passage des extrémités libres des brins du lacet, dans la plaque, peuvent être de différentes formes correspondant à la forme de la section transversale droite du lacet, e.g. : circulaire, oblong, rectangulaire trapézoïdale, triangulaire Advantageously, the passage holes of the free ends of the lace strands, in the plate, may be of different shapes corresponding to the shape of the right cross section of the lace, e.g.: circular, oblong, rectangular trapezoidal, triangular
Description détaillée de l'invention Le matériau silicone élastomère DETAILED DESCRIPTION OF THE INVENTION The elastomeric silicone material
Le lacet selon l'invention est réalisé de préférence en une seule pièce par une technique de formage conventionnel qui peut être l'injection moulage ou l'extrusion d'un silicone élastomère, se présentant sous forme liquide puis réticulant dans le moule ou en sortie de filière d'extrusion. L'élastomère silicone ou caoutchouc silicone peut-être du type gomme élastomère (SR), vulcanisant à haute température (HTV) sous l'action d'un peroxyde, ou à température ambiante (RTV) soit sous l'action d'un silicate d 'alcoyle en présence d'un catalyseur organo-stanneux, soit en présence d'un catalyseur de réticulation en particulier à base de sel de platine. Ces élastomères silicones sont également dénommés HCR : "High Consistency Silicone Rubber". Il existe des HCR peroxyde, platine ou fluoré. Il peut être en variante du type liquide (LSR) ou extra liquide (XLR) vulcanisant en général à chaud grâce à un catalyseur de réticulation en particulier à base de sel de platine et dont la viscosité est par exemple comprise entre 30 et 200 Pa.s. et plus précisément de l'ordre de 100 Pa.s. Il pourrait également s'agir de silicone cellulaire. Pour améliorer la résistance au déchirement de l'élastomère silicone réticulé formant le lacet, il est préconisé conformément à l'invention d'incorporer dans la formulation de l'élastomère par exemple, des silices pyrogéniques dont les surfaces spécifiques BET sont >100 m2/g, des silices de précipitation, des charges inactives, par exemple à base de quartz ou de terre de diatomées ou du noir de carbone. The lace according to the invention is preferably made in one piece by a conventional forming technique which may be injection molding or extrusion of an elastomeric silicone, which is in liquid form and crosslinking in the mold or in the mold extrusion die. The silicone elastomer or silicone rubber may be of the elastomeric rubber type (SR), vulcanizing at high temperature (HTV) under the action of a peroxide, or at room temperature (RTV) or under the action of a silicate of alkyl in the presence of an organo-stannous catalyst, or in the presence of a crosslinking catalyst, in particular based on platinum salt. These silicone elastomers are also referred to as HCR: "High Consistency Silicone Rubber". There is peroxide, platinum or fluorinated HCR. It may alternatively be of the liquid type (LSR) or extra liquid (XLR) vulcanizing generally hot by means of a crosslinking catalyst in particular based on platinum salt and whose viscosity is for example between 30 and 200 Pa. s. and more precisely of the order of 100 Pa.s. It could also be cellular silicone. To improve the tear strength of the crosslinked silicone elastomer forming the lace, it is recommended according to the invention to incorporate in the formulation of the elastomer, for example, pyrogenic silicas whose BET surface areas are> 100 m 2. / g, precipitated silicas, inactive fillers, for example based on quartz or diatomaceous earth or carbon black.
Après réticulation, la dureté shore A est par exemple comprise entre 30 et 100, et de préférence entre 40 et 80.  After crosslinking, the Shore A hardness is for example between 30 and 100, and preferably between 40 and 80.
La structure du lacet The structure of the lace
De part et d'autre de sa zone d'identification médiane, le lacet est un cordon ou un fil en élastomère silicone de section transversale droite polygonale, par exemple rectangulaire, circulaire, ou toute autre forme adaptée à l'enfilage au travers des passants de la chaussure. On either side of its middle identification zone, the lace is a cord or a silicone elastomer wire of polygonal straight cross-section, for example rectangular, circular, or any other form suitable for threading through passers-by of the shoe.
De la même façon, ses dimensions en section transversale droite doivent être telles qu'elles permettent le passage dans les passants de la chaussure, par exemple quelques millimètres. In the same way, its dimensions in right cross section must be such that they allow passage through the loops of the shoe, for example a few millimeters.
Le lacet peut être de différentes longueurs correspondant aux standards en vigueur par exemple : de 800 à 1800 mm. The lace can be of different lengths corresponding to the standards in force for example: from 800 to 1800 mm.
Suivant un mode de réalisation préférée, le lacet est constitué de deux brins solidaires chacun dans la partie médiane dudit lacet, de la zone d'identification, laquelle forme, de préférence, avec les deux brins, une seule et même pièce moulée, en particulier injectée-moulée.  According to a preferred embodiment, the lace is constituted by two strands integral each in the middle part of said lace, of the identification zone, which preferably forms, with the two strands, one and the same molded part, in particular injected-molded.
Par exemple, la zone d'identification fait partie intégrante du lacet. Le lacet constitué de la zone d'identification et des deux brins est réalisé de préférence dans un seul et même matériau, à savoir l'élastomère silicone, et avantageusement dans une même opération. For example, the identification area is an integral part of the lace. The lace consisting of the identification zone and the two strands is preferably made of a single material, namely the silicone elastomer, and advantageously in the same operation.
Suivant un autre mode de réalisation avantageux, les deux brins du lacet sont sensiblement de même longueur et la zone d'identification est alors un moyen de centrage du lacet entre les deux passants inférieurs situés de part et d'autre et à la base du passage du lacet sur la chaussure.According to another advantageous embodiment, the two strands of the lace are of substantially the same length and the identification zone is then a centering means of the lace between the two lower loops located on either side and at the base of the passage lace on the shoe.
Par ailleurs, conformément à l'invention, les brins du lacet de part et d'autre de la zone d'identification peuvent avoir, indépendamment l'un de l'autre, une section constante ou variable en forme ou en dimensions. Moreover, according to the invention, the strands of the lace on either side of the identification zone may have, independently of one another, a constant or variable section in shape or dimensions.
Un modèle destiné à la course à pied simple, peut présenter par exemple deux brins de section rectangulaire sur toute leur longueur et terminés chacun par un biseautage d'environ 30° permettant l'enfïlement aisé du lacet dans les œillets des chaussures.  A model intended for simple running, may for example have two strands of rectangular section along their entire length and each terminated by a beveling of about 30 ° for easy enfilement of the lace in the eyelets of the shoes.
Le laçage peut se terminer ou non par un nœud traditionnel ou par un petit nœud à la fin de chaque dernier œillet et en coupant le surplus de lacet.  The lacing may or may not end with a traditional knot or a small knot at the end of each last grommet and cut off the excess lace.
En lieu et place du nœud traditionnel, il est préférable, conformément à l'invention de terminer le laçage par blocage des extrémités libres des brins du lacet, par rapport à la chaussure, à l'aide de la plaque selon invention nommée « BlocKnot », laquelle est pourvue de plusieurs passages qui retiennent le lacet par entrelacement du lacet dans les passages et donc par grip. Le lacet en silicone à un coefficient de friction tel qu'il est possible de garder la position du lacet par rapport à la plaque de blocage, après introduction dudit lacet dans les passages de ladite plaque, à l'instar d'une piqûre de couture. Instead of the traditional knot, it is preferable, in accordance with the invention to terminate the lacing by locking the free ends of the strands of the lace, with respect to the shoe, using the plate according to the invention named "BlocKnot" which is provided with several passages which retain the lace by interlacing the lace in the passages and thus by grip. The silicone lace has a coefficient of friction such that it is possible to keep the position of the lace relative to the locking plate, after introduction of said lace in the passages of said plate, like a seam stitching .
Un modèle destiné aux sports d'appuis, peut présenter par exemple deux brins ayant chacun des sections différentes sur leur longueur réparties sur plusieurs zones distinctes.  A model for sports support, for example may have two strands each having different sections along their length spread over several separate areas.
Ce modèle peut être décliné en trois tailles répondant ainsi au besoin des utilisateurs de différentes tailles de pied : S - M - L. La taille L peut correspondre par exemple à une longueur de 920 mm.  This model can be declined in three sizes thus meeting the needs of users of different sizes of foot: S - M - L. The size L may correspond for example to a length of 920 mm.

Comme montré sur la figure 1 , le lacet 1 selon l'invention permet de sécuriser l'attache du pied de l'utilisateur dans une chaussure 2, qui est, en l'occurrence, est par exemple, une chaussure de sport. Classiquement, ce lacet 1 est disposé sur un passage 3 prévu sur le cou-de-pied de la chaussure 2 et délimité par deux bords latéraux 4,5 et par une languette 6 de la chaussure 2. Ces deux bords latéraux 4,5 présentent des passants 7 dans lesquels est enfilé en zigzags le lacet 7, à partir de la base du passage 3 et plus particulièrement des deux passants inférieurs 7i. As shown in Figure 1, the lace 1 according to the invention secures the attachment of the foot of the user in a shoe 2, which is, in this case, is for example, a sports shoe. Classically, this lace 1 is arranged on a passage 3 provided on the instep of the shoe 2 and delimited by two lateral edges 4,5 and by a tongue 6 of the shoe 2. These two lateral edges 4,5 have passers 7 in which is zigzagged lace 7, from the base of the passage 3 and more particularly the two lower loops 7i.
Ce lacet 1 est un fil en élastomère silicone réticulé constitué de deux brins 8i et 82 chacun solidaire dans la partie médiane du lacet 1 , d'une zone d'identification 9, qui est constituée en l'espèce et par exemple par une plaque de forme rectangulaire, et qui présente un signe 10 verbal d'identification et/ou de communication, formé sur les figures 2B, 3 & 5 par la dénomination "WOLF" et sur la figure 2A par la dénomination "UNCIA". This lace 1 is a cross-linked silicone elastomer yarn consisting of two strands 8i and 8 2 each integral in the middle part of the lace 1, with an identification zone 9, which is constituted in this case and for example by a plate of rectangular shape, and which has a verbal sign of identification and / or communication, formed in Figures 2B, 3 & 5 by the name "WOLF" and in Figure 2A by the name "UNCIA".
Les deux brins 8i & 82 du lacet 1 ont dans cet exemple de réalisation une section transversale droite rectangulaire (e.g. longueur de 4 mm et largeur de 2 mm) formant, avec la plaque/zone d'identification 9, une seule et même pièce injectée-moulée. Comme cela apparaît sur les figures 3 à 6, le lacet 1, et plus particulièrement sa plaque/zone d'identification 9, est prise en sandwich entre, d'une part, un support 11 rectangulaire situé en dessous de la plaque/zone d'identification 9, et, d'autre part, une coque transparente 12 (Figure 4) disposée en regard de la face extérieure apparente 13 de la plaque/zone d'identification 9. Par ailleurs, la plaque/zone d'identification 9 comprend des évidements 14 qui correspondent au signe 10 verbal d'identification et/ou de communication, en l'occurrence la dénomination «WOLF ». Le support 11 rectangulaire qui est sensiblement de même dimension que la plaque/jaune d'identification neuve et qui est réalisée par exemple dans une matière plastique moulée telle que le polychlorure de vinyle (PVC), le polyéthylène téréphtalate (PET) ou le polyéthylène (PE), présente sur sa face supérieure 15 (par référence à la disposition des figures 1, 2A, 2B et 3) un motif 16 en relief correspondant au signe 10 verbal d'identification et/ou de communication, en l'occurrence la dénomination «WOLF », qui est enfoncé dans les évidements 14 de la plaque/zone d'identification 9 et qui possède une hauteur telle par rapport à l'épaisseur de la plaque/zone d'identification 9, que la partie supérieure dudit motif 16 est saillante par rapport à la face extérieure apparente 13 de la plaque/zone d'identification 9. The two strands 8i and 8 2 of the lace 1 have in this embodiment a rectangular cross section (eg length of 4 mm and width of 2 mm) forming, with the plate / identification zone 9, a single piece injected-molded. As it appears in FIGS. 3 to 6, the lace 1, and more particularly its plate / identification zone 9, is sandwiched between, on the one hand, a rectangular support 11 located below the plate / zone d 9, and, on the other hand, a transparent shell 12 (FIG. 4) disposed opposite the apparent external face 13 of the identification plate / zone 9. Furthermore, the identification plate / zone 9 comprises recesses 14 which correspond to the verbal sign of identification and / or communication, in this case the denomination "WOLF". The rectangular support 11 which is substantially of the same size as the new identification plate / yellow and which is made for example of a molded plastic such as polyvinyl chloride (PVC), polyethylene terephthalate (PET) or polyethylene ( PE), has on its upper face 15 (with reference to the arrangement of Figures 1, 2A, 2B and 3) a pattern 16 in relief corresponding to the verbal sign of identification and / or communication, in this case the denomination "WOLF", which is pressed into the recesses 14 of the plate / identification area 9 and which has a height such as to the thickness of the plate / identification area 9, that the upper part of said pattern 16 is protruding with respect to the apparent external face 13 of the plate / identification zone 9.
Ces caractéristiques structurelles créent un effet visuel esthétique et attractif qui met particulièrement en valeur le signe 10 verbal d'identification et/ou de communication en l'occurrence la dénomination «WOLF ». These structural features create an aesthetic and attractive visual effect that particularly emphasizes the verbal sign of identification and / or communication in this case the denomination "WOLF".
Cet effet est encore accentué par la coque transparente 12 qui est ancrée dans la plaque/zone d'identification 9 au moyen de quatre picots 17 qui sont introduits et retenus dans des trous This effect is further accentuated by the transparent shell 12 which is anchored in the plate / identification zone 9 by means of four pins 17 which are introduced and retained in holes
18,19 alignés et ménagés, respectivement, dans la plaque/zone d'identification 9 en élastomère silicone et dans le support 11 rectangulaire, comme cela apparaît sur la figure 3. 18,19 aligned and arranged, respectively, in the plate / identification zone 9 silicone elastomer and in the rectangular support 11, as shown in Figure 3.
Ce motif 16 en relief et cette coque transparente 12 optimisent la visibilité commerciale du lacet This pattern 16 in relief and this transparent shell 12 optimize the commercial visibility of the lace
1. 1.
La figure 1 montre que le lacet 1 équipé de sa plaque/zone 9 porteuse du signe 10 verbal et/ou figuratif d'identification et/ou de communication, se détache de la chaussure 1 et apparaît au consommateur comme un accessoire à part entière et indépendant de la chaussure 2. La disposition de la plaque/zone d'identification 9 à la base du passage 3 de la chaussure 2, entre les 2 passants inférieurs 7i, est une place de choix pour la mise en valeur de la marque du lacet 1. Comme montrée sur la figure 6, la face inférieure 20 du support 1 1 rectangulaire, reposant sur la languette 6 de la chaussure 2, entre les deux passants inférieurs 7i du passage 3, peut être utilisée comme support d'informations 21 d'identification ou de marquage/traçage anticontrefaçons.  Figure 1 shows that the lace 1 equipped with its plate / area 9 bearing the verbal sign 10 and / or figurative identification and / or communication, detaches from the shoe 1 and appears to the consumer as an accessory in its own right and independent of the shoe 2. The layout of the plate / identification zone 9 at the base of the passage 3 of the shoe 2, between the 2 lower loops 7i, is a place of choice for the enhancement of the lace mark 1. As shown in FIG. 6, the lower face 20 of the rectangular support 11, resting on the tongue 6 of the boot 2, between the two lower loops 7i of the passage 3, can be used as information carrier 21 of identification or marking / tracing anti-counterfeits.
En outre, selon des variantes avantageuses de l'invention, le support 11 rectangulaire et/ou la plaque/zone d'identification 9 en élastomère silicone moulé, pourrai(en)t contenir ou supporter des dispositifs électroniques miniaturisés (RFID, capteurs localisation, capteurs cinématique, capteurs paramètres physiologiques, capteurs météorologiques, émetteur/récepteur,...), des sources d'énergie électrique, des lampes. .. Autant de moyens permettant de doter le lacet (1) de multiples fonctionnalités au service de l'utilisateur. In addition, according to advantageous variants of the invention, the rectangular support 11 and / or the identification plate / zone 9 made of molded silicone elastomer may contain or support miniaturized electronic devices (RFID, location sensors, kinematic sensors, physiological parameters sensors, meteorological sensors, transceiver, ...), sources of electrical energy, lamps. .. So many ways to provide the lace (1) multiple features in the service of the user.
Les figures 7A à 7D montrent une lere variante de la coque 12 constituée de 2 parties 12i et 122 articulées et encapsulant la plaque/zone d'identification 9 en élastomère silicone se prolongeant par les 2 brins 81,82 réalisés dans la même matière et en une seule pièce. Le signe verbal 10 d'identification et/ou de communication est ici constitué par la dénomination « S-LACE ». 7A to 7D show a variant of the era shell 12 consists of two parts 12i and 12 two articulated and encapsulating the plate / identification zone 9 silicone elastomer extending through the two strands 81,82 made of the same material and in one piece. The verbal sign 10 of identification and / or communication is here constituted by the name "S-LACE".
Les figures 8 A à 8D montrent une 2eme variante de la coque 12 constituée là encore de 2 parties 12i et 122 articulées et encapsulant la plaque/zone d'identification 9 en élastomère silicone se prolongeant par les deux brins 81,82 réalisés dans la même matière et en une seule pièce. Le signe verbal 10 d'identification et/ou de communication est ici encore constitué par la dénomination « S-LACE ». Mais, de manière différente de la première variante des figures 7A- 7D, la plaque/zone d'identification 9 comprend 2 extrémités formant chacune une région 8O1 8Ο2 intermédiaire de liaison avec le brin 81,82 respectivement. Ces régions 8O1 8Ο2 terminales sont plus épaisses que le reste de la plaque/zone d'identification 9. La coque 12 transparente articulée enveloppe cette zone amincie située entre les deux régions 8O1 8O2 terminales. Figures 8 A to 8D show a 2 nd embodiment of the shell 12 again consists of two parts 12i and 12 two articulated and encapsulating the plate / identification zone 9 silicone elastomer extending through the two strands 81,82 made in the same material and in one piece. The verbal sign 10 of identification and / or communication is here again constituted by the name "S-LACE". But, unlike the first variant of FIGS. 7A-7D, the plate / identification zone 9 comprises 2 ends each forming an intermediate 8O1 8Ο2 region of bond with the strand 81, 82 respectively. These 8O1 8Ο2 end regions are thicker than the rest of the plate / identification zone 9. The hinged transparent shell 12 envelops this thinned zone located between the two terminal 8O1 8O2 regions.
Dans les deux variantes des figures 7A-7D et 8A à 8D, les deux parties articulées 12i et 122 de la coque transparente 12 sont assemblées l'une à l'autre par exemple au moyen de clips. La fabrication du lacet In both variants of FIGS. 7A-7D and 8A to 8D, the two articulated parts 12i and 12 2 of the transparent shell 12 are assembled to one another for example by means of clips. Lace making
Le lacet 1 est avantageusement injecté-moulé à partir d'une matière première silicone non réticulée, par exemple du type de celle à base de LSR ou HCR et commercialisée sous la dénomination ELASTOSIL® R, FLR ou LR, ou encore CENUSIL® R 340 par la société WACKER.  The lace 1 is advantageously injected-molded from a non-crosslinked silicone raw material, for example of the type based on LSR or HCR and marketed under the name ELASTOSIL® R, FLR or LR, or else CENUSIL® R 340 by the company WACKER.
Le dispositif d'injection moulage peut être par exemple une machine de moulage par injection de caoutchouc en silicone YIZUMI YL-V360L, YL-AB500L ou YL-AB550L. The injection molding device may be for example a YIZUMI YL-V360L, YL-AB500L or YL-AB550L silicone rubber injection molding machine.
Un autre objet de l'invention est formé par un procédé de fabrication des lacets tels que définis dans le présent exposé, ledit procédé consistant essentiellement à : Another object of the invention is formed by a method of manufacturing laces as defined in the present disclosure, said method consisting essentially of:
- mettre en œuvre une matière première silicone non réticulée, comprenant un ou plusieurs polymères silicones et des charges, et, éventuellement au moins l'un des composés suivants : catalyseur(s), réticulant(s), pigment(s), agent(s) antiadhésif(s), plastifiant(s), promoteur(s) d'adhérence; implementing a non-crosslinked silicone raw material, comprising one or more silicone polymers and fillers, and optionally at least one of the following compounds: catalyst (s), crosslinking agent (s), pigment (s), agent ( s) nonstick (s), plasticizer (s), adhesion promoter (s);
- effectuer le formage du lacet par extrusion ou injection moulage de cette matière première silicone, de telle sorte que cette matière première réticule et se transforme en élastomère silicone durci, après mise en forme au sein de l'extrudeuse ou du moule ;  effecting the forming of the lace by extrusion or injection molding of this silicone raw material, such that this raw material cross-links and is transformed into a cured silicone elastomer, after forming within the extruder or the mold;
- éventuellement découper à la bonne longueur le lacet ;  - optionally cut the lace to the correct length;
- récupérer les lacets ainsi obtenus ;  - recover the laces thus obtained;
- refroidir lesdits lacets ; - conditionner lesdits lacets en vue de leur commercialisation. - Cool said laces; - conditioning said laces for sale.
La plaque de blocage des .extrémités, libres, des. brins, .du .lacet .par rapport, à. la. chaussure Le matériau de la plaque « BlocKnot » Blocking plate . ends, free, of . strands. of . lace . compared to . the . shoe The material of the plate «BlocKnot»
La plaque « BlocKnot » selon l'invention est réalisée de préférence en une seule pièce par différentes techniques de fabrication selon le matériau choisi : par exemple moulage d'un matériau plastique puis perforation pour réaliser les passages du lacet dans la plaque. II est préconisé conformément à l'invention d'utiliser des matériaux dits semi-rigides afin d'obtenir une souplesse pour une harmonisation du galbe du pied et de la plaque et un minimum de rigidité pour bloquer le lacet par son passage dans la succession de trous. À titre d'exemple de matériau semi rigide adapté, on peut citer : le polypropylène en en plaque d'environ 1 mm d'épaisseur.  The "BlocKnot" plate according to the invention is preferably made in one piece by different manufacturing techniques depending on the chosen material: for example molding a plastic material and perforation to make the lace passes through the plate. It is recommended according to the invention to use so-called semi-rigid materials in order to obtain flexibility for a harmonization of the curve of the foot and the plate and a minimum of rigidity to block the lace through its passage in the succession of holes. As an example of suitable semi-rigid material, mention may be made of: polypropylene in a plate approximately 1 mm thick.
Selon une variante et pour des raisons notamment esthétiques, le bois peut être utilisé comme matériau constitutif de la plaque. Un usinage avec un galbe est réalisé pour respecter la forme du pied, plus particulièrement du coup de pied. According to a variant and for particularly aesthetic reasons, the wood can be used as the constituent material of the plate. A machining with a curve is made to respect the shape of the foot, especially the kick.
Selon une autre variante, on met en œuvre une matière souple telle qu'un matériau silicone silicone, par exemple du même type que celui constituant le lacet selon l'invention. La souplesse d'un matériau silicones permet une très bonne adaptation à la forme du pied. En outre, le silicone de la plaque bloquante contribuerait comme le silicone du lacet au blocage (pas de glissement : coefficient de friction élevé) de ces 2 éléments l'un par rapport à l'autre.  According to another variant, use is made of a flexible material such as a silicone silicone material, for example of the same type as that constituting the lace according to the invention. The flexibility of a silicone material allows a very good adaptation to the shape of the foot. In addition, the silicone of the blocking plate would contribute as the silicone lace blocking (no slip: high coefficient of friction) of these 2 elements relative to each other.
Pour l'utilisation sur des lacets de types élastomères réclamant un chaussage et déchaussage sans défaire les nœuds, nous préconisons l'utilisation d'un matériau résistant à l'étirement. For use on laces of elastomeric type requiring a boot and heaving without undoing the knots, we recommend the use of a material resistant to stretching.
La structure de la plaque « BlocKnot » The structure of the "BlocKnot" plate
La dite plaque est généralement de forme rectangulaire. Mais elle peut avoir des variantes comme le triangle, le cercle, etc. Elle peut aussi avoir des formes dites personnalisées pouvant reprendre le contour d'un logo d'une marque, par exemple.  The said plate is generally rectangular in shape. But it can have variants like triangle, circle, etc. It can also have so-called custom shapes that can take the outline of a logo of a brand, for example.
Ses dimensions peuvent être aussi variantes selon la nature du matériau ou la taille de la chaussure. L'invention est souvent réalisée dans une dimension dite standard de 20 mm de large sur 50 mm de long. Les extrêmes sont de 50 mm de large sur 100 mm de long. Its dimensions may also be different depending on the nature of the material or the size of the shoe. The invention is often made in a so-called standard dimension of 20 mm wide and 50 mm long. The extremes are 50 mm wide and 100 mm long.
Son épaisseur est aussi variable selon le matériau choisi. Si nous reprenons l'exemple du polypropylène une plaque de 20 mm sur 50 mm aura une épaisseur variant entre 0.5 mm et 1.2 mm d'épaisseur, 0.8mm étant une bonne moyenne. Les trous de passage des lacets peuvent être de différentes formes. Leur taille est généralement plus petite que le lacet utilisé. Le passage du lacet dans la succession de 3 trous (au minimum), qui au demeurant sont plus petits, bloque le lacet par freinage et par grip. Its thickness is also variable depending on the chosen material. If we take again the example of the polypropylene a plate of 20 mm on 50 mm will have a thickness varying between 0.5 mm and 1.2 mm of thickness, 0.8mm being a good average. The passage holes of the laces can be of different shapes. Their size is usually smaller than the lace used. The passage of the lace in the succession of 3 holes (at least), which in fact are smaller, blocks the lace braking and grip.
