Description

Article chaussant à serrage facilité Footwear article with easy tightening
La présente invention se rapporte à un article chaussant comprenant une chaussure présentant une semelle et une tige équipée d'au moins une partie flexible, ledit article chaussant étant doté d'un système de serrage conçu de manière à faciliter le serrage de ladite partie flexible sur un pied introduit dans la chaussure.The present invention relates to an article of footwear comprising a shoe having a sole and a shaft equipped with at least one flexible part, said article of footwear being provided with a tightening system designed to facilitate the tightening of said flexible part on a foot introduced into the shoe.
Un tel article chaussant est par exemple connu du document US 6 378 230 qui décrit une chaussure équipée d'un système de serrage mécanique permettant un serrage automatique d'une partie de la tige sur le pied. Le desserrage est obtenu en exerçant des efforts avec l'autre chaussure sur un élément faisant saillie en partie arrière de la chaussure.Such footwear is for example known from US 6,378,230 which discloses a shoe equipped with a mechanical clamping system for automatic clamping of a portion of the rod on the foot. Loosening is obtained by exerting efforts with the other shoe on an element projecting in the rear part of the shoe.
Un autre article chaussant visant à faciliter les opérations de serrage/desserrage est divulgué dans le document WO 04034831. L'homme du métier demeure cependant dans l'attente d'un article chaussant dont le système de serrage est fiable, simple, d'un faible encombrement, d'un coût maîtrisé, facile à mettre en œuvre, aussi bien par des sportifs cherchant à optimiser leurs performances, que par des enfants, des personnes âgées ou encore des personnes pouvant présenter un handicap. La présente invention a pour but de répondre en tout ou partie à cette attente, et consiste pour cela en un article chaussant comprenant une chaussure présentant une semelle et une tige équipée d'au moins une partie flexible, ledit article chaussant comprenant un système de serrage conçu de manière à faciliter le serrage et le desserrage de ladite partie flexible sur un pied introduit dans la chaussure, caractérisé en ce que le système de serrage comprend une source d'énergie électrique, des moyens d'entraînement motorisés alimentés par la source d'énergie électrique, et des moyens de serrage reliés aux moyens d'entraînement et à ladite partie flexible de manière à permettre le serrage ou le desserrage de ladite partie flexible sur le pied. Ainsi, l'incorporation de moyens d'entraînement motorisés activés par une source d'énergie électrique permet notamment d'éviter d'avoir à faire usage de sa force physique, et de régler finement le serrage de la chaussure autour du pied.Another article of footwear intended to facilitate the tightening / loosening operations is disclosed in document WO 04034831. The person skilled in the art, however, remains waiting for an article of footwear whose clamping system is reliable, simple, of a small footprint, cost-effective, easy to implement, both by athletes seeking to optimize their performance, by children, the elderly or people who may have a disability. The present invention aims to meet all or part of this expectation, and for this purpose consists of a footwear comprising a shoe having a sole and a rod equipped with at least one flexible portion, said footwear comprising a clamping system designed to facilitate the tightening and loosening of said flexible part on a foot introduced into the shoe, characterized in that the clamping system comprises a source of electrical energy, motorized drive means powered by the source of electrical energy, and clamping means connected to the drive means and said flexible portion so as to allow the clamping or loosening of said flexible portion on the foot. Thus, the incorporation of motorized drive means activated by a source of electrical energy makes it possible in particular to avoid having to use its physical strength, and to finely adjust the tightening of the shoe around the foot.
Selon un premier mode de réalisation préféré de l'invention, la source d'énergie électrique et les moyens d'entraînement sont disposés dans au moins un évidement ménagé dans la semelle. Avantageusement, la source d'énergie électrique comprend une batterie électrique rechargeable par l'intermédiaire d'au moins un élément de connexion électrique accessible depuis l'extérieur de la chaussure.According to a first preferred embodiment of the invention, the source of electrical energy and the drive means are arranged in at least one recess provided in the soleplate. Advantageously, the source of electrical energy comprises a rechargeable electric battery via at least one electrical connection element accessible from the outside of the shoe.
En variante, il doit être bien compris que tout type de batterie peut être employé, et notamment une batterie pouvant se recharger par vibrations.Alternatively, it should be understood that any type of battery can be used, including a battery that can be recharged by vibration.
Selon un deuxième mode de réalisation préféré de l'invention, la source d'énergie électrique et les moyens d'entraînement sont inclus dans un boîtier distinct de la chaussure, et cette dernière est équipée d'au moins un élément de connexion mécanique accessible depuis l'extérieur et destiné à coopérer avec au moins un élément de connexion mécanique complémentaire présenté par ledit boîtier. Cette configuration permet alors de réduire le nombre d'éléments devant être disposés dans la semelle, et au final permet de diminuer de façon non négligeable la masse globale de la chaussure ainsi équipée. Avantageusement, un jeu d'interrupteurs de commande accessible depuis l'extérieur est prévu en vue d'activer les moyens d'entraînement afin d'assurer le serrage ou le desserrage de ladite partie flexible. En variante, il doit être bien compris que l'activation des moyens d'entraînement peut être effectuée à l'aide d'une télécommande interagissant avec des moyens de commande complémentaires intégrés dans la chaussure.According to a second preferred embodiment of the invention, the source of electrical energy and the drive means are included in a separate housing of the boot, and the latter is equipped with at least one mechanical connection element accessible from the outside and intended to cooperate with at least one complementary mechanical connection element presented by said housing. This configuration then makes it possible to reduce the number of elements to be arranged in the sole, and in the end makes it possible to reduce in a significant way the overall mass of the shoe thus equipped. Advantageously, a set of control switches accessible from the outside is provided to activate the drive means to ensure the tightening or loosening of said flexible portion. Alternatively, it should be understood that the activation of the drive means can be performed using a remote interacting with additional control means integrated into the shoe.
En variante, un article chaussant selon l'invention peut comprendre au moins un premier capteur de pression en partie avant de la semelle et un deuxième capteur de pression en partie arrière de la semelle. De plus, la source d'énergie électrique et/ou les moyens d'entraînement comprennent de préférence des moyens de détection et de commande conçus pour actionner le serrage de ladite partie flexible lorsque les deux capteurs de pression sont activés.Alternatively, an article of footwear according to the invention may comprise at least a first pressure sensor at the front of the sole and a second pressure sensor at the rear of the sole. In addition, the electrical power source and / or the drive means preferably comprise detection and control means designed to actuate the clamping of said flexible portion when the two pressure sensors are activated.
Préférentiellement, la tige comprend une languette équipée d'un troisième capteur de pression. La source d'énergie électrique et/ou les moyens d'entraînement comprendront avantageusement des moyens de détection et de commande conçus pour actionner le desserrage de ladite partie flexible lorsque le troisième capteur de pression sera activé.Preferably, the rod comprises a tongue equipped with a third pressure sensor. The electrical power source and / or the drive means will advantageously comprise detection and control means designed to actuate the loosening of said flexible part when the third pressure sensor is activated.
Selon une variante de réalisation de l'invention, les moyens de serrage comprennent au moins un câble de serrage rattaché à un ensemble de serrage conçu pour être entraîné par les moyens d'entraînement de manière à alternativement tirer ou relâcher ledit câble de serrage. Selon un exemple de réalisation de l'invention, le système de serrage comprend une poulie.According to an alternative embodiment of the invention, the clamping means comprise at least one clamping cable attached to a clamping assembly designed to be driven by the drive means so as to alternately pull or release said clamping cable. According to an exemplary embodiment of the invention, the clamping system comprises a pulley.
Selon un autre exemple de réalisation de l'invention, le système de serrage comprend une tige mobile en translation. Selon une variante de réalisation préférée de l'invention, la tige comprend deux parties flexibles reliées chacune à l'ensemble de serrage par l'intermédiaire d'au moins un câble de serrage. L'ensemble de serrage est alors avantageusement réalisé à l'aide d'une poulie à double réas.According to another embodiment of the invention, the clamping system comprises a rod movable in translation. According to a preferred embodiment of the invention, the rod comprises two flexible parts each connected to the clamping assembly via at least one clamping cable. The clamping assembly is then advantageously carried out using a double sheave pulley.
Préférentiellement, au moins l'ensemble de serrage est disposé dans un support logé dans un évidement ménagé dans la semelle.Preferably, at least the clamping assembly is disposed in a support housed in a recess in the sole.
Préférentiellement encore, la tige comprend deux parties flexibles reliées l'une à l'autre par l'intermédiaire d'un lacet. La chaussure peut alors conserver un aspect esthétique classique avec un laçage parant la face avant de la tige, au niveau desdites parties flexibles. Bien évidemment, la tige pourrait comprendre en variante une partie flexible rattachée à une partie fixe de la tige, ou encore deux parties flexibles reliées l'une à l'autre, par l'intermédiaire d'au moins une bande du type Velcro®Preferably, the rod comprises two flexible parts connected to each other by means of a lace. The shoe can then maintain a classic aesthetic appearance with lacing parant the front face of the rod, at said flexible portions. Of course, the rod could alternatively comprise a flexible portion attached to a fixed portion of the rod, or two flexible portions connected to one another, via at least one Velcro® type band
L'invention sera mieux comprise à l'aide de la description détaillée qui est exposée ci-dessous en regard du dessin annexé dans lequel :The invention will be better understood with the aid of the detailed description which is set out below with reference to the appended drawing in which:
La figure 1 est une vue schématique en perspective éclatée d'un article chaussant selon le premier mode de réalisation préféré de l'invention ;Figure 1 is a schematic exploded perspective view of an article of footwear according to the first preferred embodiment of the invention;

La figure 5 est une vue schématique en perspective d'un article chaussant selon l'invention comprenant des capteurs de pression.Figure 5 is a schematic perspective view of an article of footwear according to the invention comprising pressure sensors.
Dans la description détaillée qui va suivre des figures définies ci- dessus, les mêmes éléments ou les éléments remplissant des fonctions identiques pourront conserver les mêmes références de manière à simplifier la compréhension de l'invention. Un article chaussant selon le premier mode de réalisation de l'invention, tel que représenté à la figure 1 , comprend une chaussure 1 comportant une semelle 2 sur laquelle est rapportée puis fixée une tige 3 présentant deux parties flexibles 4 disposées de part et d'autre d'un axe central longitudinal (non représenté).In the following detailed description of the figures defined above, the same elements or elements fulfilling identical functions may retain the same references so as to simplify the understanding of the invention. An article of footwear according to the first embodiment of the invention, as represented in FIG. 1, comprises a shoe 1 comprising a sole 2 on which is attached and then fixed a rod 3 having two flexible portions 4 disposed on either side of a longitudinal central axis (not shown).
La semelle 2 possède une face interne 5 dans laquelle est creusé un premier évidement 6 destiné à servir de logement à un système de serrage 7.The sole 2 has an inner face 5 in which is hollowed a first recess 6 intended to serve as a housing for a clamping system 7.
Plus précisément, ce système de serrage 7 se décompose principalement en une batterie 8 constituant une source d'énergie électrique, en des moyens d'entraînement réalisés sous la forme d'un moteur rotatif 9, et en des moyens de serrage comprenant, d'une part, un ensemble de serrage 10, et d'autre part, un câble de serrage 11 , qui possède deux extrémités 1 1 a, et qui lie les deux parties flexibles 4 l'une à l'autre par le biais de plots 25 fixés dans ces dernières.More specifically, this clamping system 7 is broken down mainly into a battery 8 constituting a source of electrical energy, drive means in the form of a rotary motor 9, and clamping means comprising: on the one hand, a clamping assembly 10, and on the other hand, a clamping cable 11, which has two ends 11a, and which links the two flexible parts 4 to each other by means of studs 25 fixed in the latter.
La batterie 8 est par exemple du type employé de nos jours dans les combinés de téléphonie mobile, à savoir des piles lithium extra-plates et ultra-légères. Cette batterie 8 est de préférence reliée à un élément de connexion électrique 12 par un jeu de câbles électriques 13, ledit élément de connexion électrique 12 étant logé dans un deuxième évidement 14 ménagé dans la face interne 5 de la semelle 2, et étant accessible depuis l'extérieur de ladite semelle 2. La batterie 8 pourra être ainsi rechargée régulièrement par l'intermédiaire d'un câble alimentation électrique (non représenté) connecté à une prise électrique et à l'organe de connexion électrique 12.The battery 8 is for example of the type used today in mobile phone handsets, namely ultra-thin and ultra-light lithium batteries. This battery 8 is preferably connected to an electrical connection element 12 by a set of electric cables 13, said electrical connection element 12 being housed in a second recess 14 formed in the inner face 5 of the sole 2, and being accessible from the outside of said soleplate 2. The battery 8 can thus be recharged regularly via a power supply cable (not shown) connected to an electrical outlet and the electrical connection member 12.
L'ensemble de serrage est réalisé sous la forme d'une poulie 10 à double réas 15, 16 connectée mécaniquement au moteur rotatif 9, et disposée dans le prolongement de ce dernier.The clamping assembly is in the form of a pulley 10 double sheaves 15, 16 mechanically connected to the rotary motor 9, and arranged in the extension thereof.
Le moteur rotatif 9 ainsi que la poulie 10 sont intégrés dans un support 17 dont la forme est complémentaire de celle du premier évidement 6. Ce support 17 incorpore deux interrupteurs de commande 18, 19 assurant la liaison électrique entre la batterie 8 et le moteur rotatif 9 par l'intermédiaire de câbles de commande 20, 21. Ce support 17 comporte deux alésages 22, 23 ménagés respectivement de part et d'autre de la poulie 10, et traversés chacun par l'une des deux extrémités 11a. Ces dernières sont alors enroulées respectivement autour des réas 15 et 16.The rotary motor 9 and the pulley 10 are integrated in a support 17 whose shape is complementary to that of the first recess 6. This support 17 incorporates two control switches 18, 19 providing the electrical connection between the battery 8 and the rotary engine 9 by means of control cables 20, 21. This support 17 has two bores 22, 23 respectively formed on either side of the pulley 10, and each through one of the two ends 11a. The latter are then wound respectively around the sheaves 15 and 16.
Les interrupteurs dé commande 1 8, 1 9 permettent ainsi de commander une mise en tension ou un relâchement des extrémités 11 a du câble de serrage 1 1 par l'intermédiaire de la poulie 10 entraînée par le moteur rotatif 9, selon que ce dernier est entraîné en rotation dans un sens ou dans un autre.The control switches 1 8, 1 9 thus make it possible to control the tensioning or loosening of the ends 11a of the clamping cable 1 1 by means of the pulley 10 driven by the motor rotary 9, as the latter is rotated in one direction or another.
Certaines parties du câble de serrage 11 peuvent être logées dans des caches 24a, 24b sensiblement tu bu l a i res afin d 'éviter q u e les déplacements du câble de serrage 11 ne génèrent une usure prématurée de la tige 3 au niveau des zones de contact avec ledit câble de serrage 11.Some parts of the clamping cable 11 can be housed in covers 24a, 24b substantially you bu lle res to prevent the movements of the clamping cable 11 generate premature wear of the rod 3 at the contact areas with said tightening cable 11.
L'article chaussant représenté à la figure 2 diffère de celui décrit précédemment par le fait qu'il comporte une chaussure 101 équipée en sus d'un lacet 26 lié de façon classique aux plots 25. II est possible d'utiliser deux câbles de serrage 11 distincts l'un de l'autre. En effet, chacun de ces câbles de serrage 11 présente alors une première extrémité 11 a fixée dans l'un des réas 15, 16 correspondant, et une seconde extrémité 11 b fixée dans l'une des deux parties flexibles 4.The footwear shown in Figure 2 differs from that described above in that it comprises a shoe 101 equipped in addition to a lace 26 conventionally connected to the pads 25. It is possible to use two clamping cables 11 distinct from each other. Indeed, each of these clamping cables 11 then has a first end 11a fixed in one of the sheaves 15, 16 corresponding, and a second end 11b fixed in one of the two flexible parts 4.
De ce fait, la chaussure 1 01 présente un aspect esthétique traditionnel avec un lacet 26 en façade.As a result, the shoe 1 01 has a traditional aesthetic appearance with a lace 26 in front.
De plus, il doit être bien compris qu'il n'est plus nécessaire de faire/défaire le nœud du lacet 25 lors du serrage/desserrage de la chaussure 101. En effet, une fois les parties flexibles 4 écartées l'une de l'autre, l'espace est suffisant pour permettre une introduction/extraction du pied sans toucher au nœud dudit lacet 25.In addition, it should be understood that it is no longer necessary to make / untie the lace node 25 during tightening / loosening of the boot 101. Indeed, once the flexible parts 4 apart one of the other, the space is sufficient to allow introduction / extraction of the foot without touching the knot of said lace 25.
Un article chaussant selon la deuxième mode de réalisation préféré de l'invention est représenté schématiquement à la figure 3. A la différence des deux articles chaussants précédemment décrits, la source d'énergie électrique et les moyens d'entraînement ne sont pas intégrés dans la chaussure 201 , mais dans un boîtier 230 muni d'un interrupteur de commande 231. Seuls les moyens de serrage sont disposés dans la semelle 2. Ces moyens de serrage comprennent notamment un ensemble de serrage réalisé sous la forme d'une poulie 10 à double réas 15, 16, et d'un câble de serrage 11.An article of footwear according to the second preferred embodiment of the invention is shown schematically in FIG. 3. Unlike the two footwear items previously described, the source of electrical energy and the drive means are not integrated into the shoe 201, but in a housing 230 provided with a control switch 231. Only the clamping means are arranged in the sole 2. These clamping means comprise in particular a clamping assembly in the form of a double pulley 10 sheaves 15, 16, and a clamping cable 11.
Plus précisément, la poulie 10 est liée à un élément de connexion mécanique réalisée sous la forme d'une roue 232 dentée à laquelle est associé un organe de blocage 233 anti-retour. Ce dernier est constitué par un bras monté pivotant autour d'un axe 234, et présente, d'une part, une première extrémité pourvue d'un ergot 235 apte à coopérer avec la denture de la roue 232, et d'autre part, une seconde extrémité, qui est rattachée à un organe de renvoi élastique 236 du type ressort, et qui fait avantageusement saillie de la semelle 2. Par ailleurs, les moyens d'entraînement comprennent un moteur rotatif (non représenté) pourvu d'un élément de connexion complémentaire 237 conçu pour être introduit dans l'orifice central de la roue 232 en vue d'entraîner cette dernière ainsi que la poulie 10 en rotation. Le desserrage peut être réalisé en exerçant au préalable une pression sur la seconde extrémité de l'organe de blocage 233, qui est accessible depuis l'extérieur, afin de libérer la roue 232 de l'ergot 235.More specifically, the pulley 10 is connected to a mechanical connection element made in the form of a toothed wheel 232 to which a non-return locking member 233 is associated. The latter is constituted by an arm pivotally mounted about an axis 234, and has, on the one hand, a first end provided with a lug 235 adapted to cooperate with the toothing of the wheel 232, and secondly, a second end, which is attached to a resilient return member 236 of the spring type, and which advantageously projects from the sole 2. Furthermore, the drive means comprise a rotary motor (not shown) provided with a complementary connecting element 237 designed to be introduced into the central orifice of the wheel 232 in order to drive the latter and the pulley 10 in rotation. The loosening can be achieved by first exerting pressure on the second end of the locking member 233, which is accessible from the outside, in order to release the wheel 232 of the lug 235.
Le support 17, dans lequel sont incorporés les moyens de serrage, peut avoir une forme sensiblement triangulaire dans une telle configuration. Un autre exemple de réalisation du système de serrage 7 est représenté à la figure 4. Les moyens d'entraînement sont constitués par un vérin électrique 9 traditionnel possédant un corps 9a duquel fait saillie une tige 9b déplaçable en translation. Cette tige 9b présente une extrémité équipée d'un embout 9c sensiblement parallélépipédique dans lequel est ménagé un orifice 9d afin de permettre le passage du câble de serrage 11. Ainsi, selon que la tige 9b sera translatée respectivement en direction du corps 9a ou dans le sens opposé, le câble de serrage 11 sera mis sous tension ou au contraire relâché. Le support 17 a sensiblement la forme d'un T dans cette configuration.The support 17, in which the clamping means are incorporated, can have a substantially triangular shape in such a configuration. Another exemplary embodiment of the clamping system 7 is shown in Figure 4. The drive means are constituted by a conventional electric cylinder 9 having a body 9a which projects a rod 9b movable in translation. This rod 9b has an end equipped with a substantially parallelepipedal tip 9c in which is formed an orifice 9d to allow the passage of the clamping cable 11. Thus, as the rod 9b will be translated respectively towards the body 9a or in the In the opposite direction, the clamping cable 11 will be energized or loosened. The support 17 has substantially the shape of a T in this configuration.
Enfin, l'article chaussant représenté à la figure 5 se différencie de celui matérialisé à la figure 1 par le fait que la chaussure 301 comprend, d'une part, deux capteurs de pression 302a, 302b disposés respectivement en partie avant et en partie arrière de la semelle 2, et d'autre part, un capteur de pression 303 intégré dans une languette 304 s'étendant de façon classique entre les parties flexibles 4. D e p l u s , d e s m oye n s de détection et de commandeFinally, the article of footwear represented in FIG. 5 differs from that shown in FIG. 1 by the fact that the boot 301 comprises, on the one hand, two pressure sensors 302a, 302b disposed respectively in the front part and in the rear part. of the sole 2, and secondly, a pressure sensor 303 integrated in a tongue 304 extending in a conventional manner between the flexible portions 4. D eplus, detection and control m eans
(non représentés) sont intégrés dans le support 17 et permettent à la fois de détecter les informations transmises par les différents capteurs de pression, et de commander l'actionnement des moyens d'entraînement 9.(not shown) are integrated in the support 17 and make it possible both to detect the information transmitted by the different pressure sensors, and to control the actuation of the drive means 9.
En l'espèce, le serrage sera automatiquement réalisé lorsque le pied exercera des contraintes à la fois sur le capteur de pression 302a et sur le capteur de pression 302b.In this case, the clamping will be automatically performed when the foot will exert constraints on both the pressure sensor 302a and the pressure sensor 302b.
Le ca pteu r d e press ion 303 permettra de commander le relâchement du câble de serrage 11 lorsque le pied aura tendance à gonfler au cours de la journée. Bien évidemment, il doit être bien compris que ce troisième capteur de pression 303 pourra le cas échéant également servir à arrêter automatiquement le serrage. De plus, dans une variante de réalisation particulièrement perfectionnée, il pourra être possible de modifier la valeur de la pression souhaitée par une commande wi-fi par exemple.The pressure sensor 303 will control the release of the clamping cable 11 when the foot will tend to inflate during the day. Of course, it should be understood that this third pressure sensor 303 may also be used to automatically stop the clamping. In addition, in an embodiment variant particularly sophisticated, it may be possible to change the value of the desired pressure by a wi-fi command for example.
Il doit être noté que le desserrage complet peut être commandé par le biais d'une télécommande coopérant avec des moyens de commande complémentaires (non représentés) intégrés dans la semelle 2, ou encore à l'aide d'un interrupteur par exemple.It should be noted that the complete loosening can be controlled by means of a remote control cooperating with complementary control means (not shown) integrated in the sole 2, or with the aid of a switch for example.
Bien que l'invention ait été décrite en liaison avec des exemples particuliers de réalisation, il est bien évident qu'elle n'y est nullement limitée et qu'elle comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci entrent dans le cadre de l'invention. Although the invention has been described in connection with particular embodiments, it is obvious that it is not limited thereto and that it comprises all the technical equivalents of the means described and their combinations if they are within the scope of the invention.
