Description
La présente invention concerne le domaine des objets présentant une structure composite avec une zone déformable. On entend par déformable le fait que la zone dispose d’une souplesse permettant le pliage de l’objet dans ladite zone et/ou que ladite zone puisse s’étirer, selon les divers cas de mise en œuvre de l’invention envisageables dont certains seront évoqués de manière non limitative dans la suite de la description.The present invention relates to the field of objects having a composite structure with a deformable zone. By deformable is meant the fact that the zone has a flexibility allowing the folding of the object in said zone and/or that said zone can stretch, according to the various possible cases of implementation of the invention, some of which will be mentioned in a non-limiting manner in the remainder of the description.
Etat de la techniqueState of the art
Traditionnellement, un objet quelconque disposant d’une articulation pour mettre en mouvement une partie de l’objet par rapport à une autre partie dudit objet, est mis en œuvre par un assemblage de pièces montées en liaison pivot entre elles soit directement soit au moyen d’une charnière ou d’un mécanisme d’actionnement agencé entre les pièces. A titre d’exemple, une aile d’avion dispose de divers volets (spoilers, aérofreins, ailerons) qui sont articulés sur la structure de l’aile d’avion, ces volets permettant de faire monter, de faire descendre ou de freiner l’avion. Une voiture peut également comporter un aileron avec un volet articulé sur une structure de l’aileron, le principe étant comparable à celui d’une aile d’avion, l’objectif étant cependant de maintenir le véhicule plaqué au sol lors d’une augmentation de vitesse en faisant varier l’inclinaison du volet de l’aileron selon la vitesse atteinte. Un véhicule de type voiture, avion ou hélicoptère, par exemple, dispose de plusieurs portes qui sont articulées sur la structure dudit véhicule au moyen de charnières. Ces conceptions – qui ne sont que des exemples – présentent pour inconvénient de ne pas être étanches à l’air, à l’eau ou à la poussière, notamment, ce qui peut engendrer des nuisances telles des turbulences, des infiltrations voire des dégradations ou des disfonctionnements.Traditionally, any object having a joint to move part of the object relative to another part of said object, is implemented by an assembly of parts mounted in a pivot connection between them either directly or by means of a hinge or an actuating mechanism arranged between the parts. For example, an airplane wing has various flaps (spoilers, airbrakes, ailerons) which are articulated on the structure of the airplane wing, these flaps making it possible to raise, lower or brake the 'plane. A car can also include a fin with a flap articulated on a structure of the fin, the principle being comparable to that of an airplane wing, the objective being however to keep the vehicle flat on the ground during an increase speed by varying the inclination of the aileron flap according to the speed reached. A vehicle of the car, airplane or helicopter type, for example, has several doors which are articulated on the structure of said vehicle by means of hinges. These designs – which are only examples – have the disadvantage of not being airtight, watertight or dustproof, in particular, which can cause nuisances such as turbulence, infiltration or even damage or damage. malfunctions.
D’autres objets, par exemple les montres, d’articles de maroquinerie (portefeuille, sac …) ou de lunettes, comprennent également des pièces articulées entre elles. Sur une montre, le bracelet est généralement articulé sur le corps de montre est maintenu fixé audit corps au moyen d’axes de pivotement ; il se produit parfois un dégagement de l’axe de pivotement vis-à-vis du corps de montre, la montre pouvant alors se détacher du poignet de la personne et tomber sur le sol, risquant d’endommager le corps de montre qui dispose d’une vitre permettant de visualiser l’heure indiqué par ladite montre. Sur une paire de lunettes, les branches sont articulées vis-à-vis de la monture au moyen de charnières munies de vis de serrage ; il se produit parfois un desserrage total de la vis en raison des manipulations répétées de la branche, la paire de lunette pouvant alors tomber du visage de la personne et les verres correcteurs se briser lors de l’impact au sol. Les articles de maroquinerie sont souvent confectionnés à partir de pièces de cuir cousues entre elles et pliées pour former des volets, comme sur un portefeuille, voire pour former un rabat, comme sur un cartable d’écolier. La sollicitation de la partie articulée sur de tels articles de maroquinerie peut conduire à sa détérioration avec l’usage.Other objects, for example watches, leather goods (wallet, bag, etc.) or glasses, also include parts that are hinged together. On a watch, the bracelet is generally articulated on the watch body and is kept fixed to said body by means of pivot axes; sometimes the pivot axis disengages from the watch body, the watch can then come off the person's wrist and fall to the ground, risking damage to the watch body which has a window allowing to visualize the time indicated by said watch. On a pair of glasses, the branches are articulated vis-à-vis the frame by means of hinges provided with tightening screws; the screw sometimes loosens completely due to repeated handling of the arm, the pair of glasses can then fall from the person's face and the corrective lenses break on impact with the ground. Leather goods are often made from pieces of leather sewn together and folded to form flaps, like on a wallet, or even to form a flap, like on a school satchel. The solicitation of the hinged part on such leather goods may lead to its deterioration with use.
La présente invention concerne un objet présentant une structure composite et une zone déformable qui est sollicitée durant l’usage. On entend par déformable, le fait que ladite zone peut se plier et/ou s’étendre lorsqu’elle travaille, durant l’usage de l’objet. L’invention peut être mise en œuvre sur des objets divers et variés, quelques exemples étant illustrés dans la suite de la description, ces objets pouvant constituer un article à part entière voire une partie d’un article. La conception de l’objet selon l’invention permet de pallier les inconvénients évoqués précédemment sur les objets conçus traditionnellement.The present invention relates to an object having a composite structure and a deformable zone which is stressed during use. By deformable is meant the fact that said zone can bend and/or expand when it works, during use of the object. The invention can be implemented on various and varied objects, some examples being illustrated in the following description, these objects being able to constitute an article in its own right or even part of an article. The design of the object according to the invention overcomes the drawbacks mentioned above on traditionally designed objects.
Selon l’invention, l’objet présente une structure composite et au moins une zone déformable qui est sollicitée durant l’usage, ledit objet comprenant une première épaisseur de matière qui comporte au moins une première couche de textile, ladite au moins une première couche de textile étant imprégnée d’une résine non réticulée et une seconde épaisseur de matière qui comporte au moins une couche de caoutchouc, la première épaisseur de matière et la seconde épaisseur de matière étant liées mécaniquement par vulcanisation, ladite première épaisseur de matière comprenant au moins une première ouverture laissant apparaître la seconde épaisseur de matière sous ladite première épaisseur de matière de manière à définir ladite au moins une zone déformable. Ainsi, la première épaisseur de matière apporte la robustesse et la rigidité à l’objet et la seconde épaisseur de matière apporte la déformabilité à l’objet dans l’au moins une zone déformable, la liaison mécanique obtenue par vulcanisation entre la première épaisseur et la seconde épaisseur permettant de structurer ledit objet tout en conservant ladite au moins une zone déformable fonctionnelle, destinée à travailler durant l’usage. Cette conception présente de nombreux avantages permettant de pallier les inconvénients précités, puisqu’elle permet de concevoir des articulations sur des objets tout en conservant une parfaite étanchéité aux fluides liquides et gazeux, notamment l’eau et l’air, voire aux substances solides ou visqueuses, évitant ainsi les infiltrations sources de perturbations, de turbulences ou de dégradations. Cela permet également de supprimer la présence de mécanisme de liaison (axe de pivotement, charnière …) entre différentes parties de l’objet pour la mise en œuvre desdites articulations.According to the invention, the object has a composite structure and at least one deformable zone which is stressed during use, said object comprising a first thickness of material which comprises at least a first layer of textile, said at least one first layer of textile being impregnated with a non-crosslinked resin and a second thickness of material which comprises at least one layer of rubber, the first thickness of material and the second thickness of material being mechanically bonded by vulcanization, the said first thickness of material comprising at least a first opening revealing the second thickness of material under said first thickness of material so as to define said at least one deformable zone. Thus, the first thickness of material provides strength and rigidity to the object and the second thickness of material provides deformability to the object in the at least one deformable zone, the mechanical connection obtained by vulcanization between the first thickness and the second thickness making it possible to structure said object while retaining said at least one functional deformable zone, intended to work during use. This design has many advantages making it possible to overcome the aforementioned drawbacks, since it makes it possible to design joints on objects while maintaining a perfect seal against liquid and gaseous fluids, in particular water and air, or even against solid substances or viscous, thus avoiding infiltrations that are sources of disturbances, turbulence or degradation. This also makes it possible to eliminate the presence of a link mechanism (pivot axis, hinge, etc.) between different parts of the object for the implementation of said joints.
Il se produit une liaison chimique entre la résine non réticulée de la première épaisseur de matière et le caoutchouc de la seconde épaisseur de matière durant la vulcanisation, ce qui permet de lier mécaniquement la première épaisseur de matière et la seconde épaisseur de matière sans aucun collage entre elles. Il convient donc de choisir une résine non réticulée et un caoutchouc qui soient compatibles chimiquement durant la vulcanisation. L’absence d’un collage entre la première épaisseur de matière et la seconde épaisseur de matière garantit une meilleure tenue de l’objet dans le temps, la séparation physique desdites épaisseurs de matière n’étant possible que par arrachement du fait de la liaison chimique mise en œuvre.A chemical bond occurs between the non-cured resin of the first layer of material and the rubber of the second layer of material during vulcanization, which makes it possible to mechanically bond the first layer of material and the second layer of material without any sticking between them. It is therefore advisable to choose a non-crosslinked resin and a rubber which are chemically compatible during vulcanization. The absence of bonding between the first thickness of material and the second thickness of material guarantees a better hold of the object over time, the physical separation of said thicknesses of material being possible only by tearing due to the binding chemical implemented.
Selon une réalisation de l’objet, ladite au moins une première ouverture est constituée d’une fente séparant ladite première épaisseur de matière en deux parties et permettant de constituer l’au moins une zone déformable. Une telle fente permet de constituer une articulation entre les deux parties de la première épaisseur soit pour modifier les orientations des deux parties soit pour étirer ou comprimer l’objet en écartant ou rapprochant lesdites deux parties.According to one embodiment of the object, said at least one first opening consists of a slot separating said first thickness of material into two parts and making it possible to form the at least one deformable zone. Such a slot makes it possible to form a joint between the two parts of the first thickness either to modify the orientations of the two parts or to stretch or compress the object by moving said two parts apart or bringing them closer together.
Selon une réalisation de l’objet, l’au moins une première couche de textile est choisie parmi le carbone, le verre, l’aramide, le polyéthylène, le polyamide, le polyester, le coton et le lin. D’autres matières demeurent utilisables dans le cadre de l’invention, selon la destination de l’objet et les conditions d’usage de celui-ci.According to one embodiment of the object, the at least one first textile layer is chosen from carbon, glass, aramid, polyethylene, polyamide, polyester, cotton and linen. Other materials can still be used in the context of the invention, depending on the destination of the object and the conditions of use thereof.
Selon une réalisation de l’objet, celui-ci comprend une troisième épaisseur de matière qui comporte au moins une seconde couche de textile, ladite au moins une seconde couche de textile étant imprégnée d’une résine non réticulée. En outre, la seconde épaisseur de matière est prise en sandwich entre la première épaisseur de matière et la troisième épaisseur de matière. En outre, ladite troisième épaisseur de matière comprend au moins une seconde ouverture laissant apparaître la seconde épaisseur de matière sous ladite troisième épaisseur de matière dans ladite au moins une zone déformable. Ainsi, la seconde épaisseur de matière est liée mécaniquement par vulcanisation, d’un côté avec la première épaisseur de matière et, de l’autre, avec la troisième épaisseur de matière. De préférence, selon cette réalisation de l’objet, l’au moins une seconde ouverture est identique à l’au moins une première ouverture, ladite au moins une seconde ouverture et ladite au moins une première ouverture étant disposées en correspondance chacune d’un côté de la seconde épaisseur de matière, de sorte à définir ladite au moins une zone déformable. Selon cette réalisation de l’objet, l’au moins une seconde couche de textile est choisie parmi le carbone, le verre, l’aramide, le polyéthylène et le polyamide. D’autres matières demeurent utilisables dans le cadre de l’invention, selon la destination de l’objet et les conditions d’usage de celui-ci. De préférence, la première épaisseur de matière et la troisième épaisseur de matière sont identiques, mais il serait possible de prévoir une première épaisseur de matière différente de la troisième épaisseur de matière, notamment une première couche de textile différente de la seconde couche de textile, voire un nombre de premières couches textiles différent du nombre de secondes couches textiles.According to one embodiment of the object, the latter comprises a third thickness of material which comprises at least one second layer of textile, said at least one second layer of textile being impregnated with a non-crosslinked resin. Further, the second material ply is sandwiched between the first material ply and the third material ply. Furthermore, said third thickness of material comprises at least one second opening revealing the second thickness of material under said third thickness of material in said at least one deformable zone. Thus, the second thickness of material is mechanically bonded by vulcanization, on one side with the first thickness of material and, on the other, with the third thickness of material. Preferably, according to this embodiment of the object, the at least one second opening is identical to the at least one first opening, said at least one second opening and said at least one first opening being each arranged in correspondence of a side of the second thickness of material, so as to define said at least one deformable zone. According to this embodiment of the object, the at least one second textile layer is chosen from carbon, glass, aramid, polyethylene and polyamide. Other materials can still be used in the context of the invention, depending on the destination of the object and the conditions of use thereof. Preferably, the first thickness of material and the third thickness of material are identical, but it would be possible to provide a first thickness of material different from the third thickness of material, in particular a first layer of textile different from the second layer of textile, or even a number of first textile layers different from the number of second textile layers.
Selon une réalisation de l’objet, la seconde épaisseur de matière comprend un tissu enduit de caoutchouc. On entend par « enduit de caoutchouc » le fait que le tissu peut être enduit sur une de ses deux faces ou sur chacune de ses deux faces de caoutchouc, dans quel cas une couche de caoutchouc est déposée sur une face de la couche de tissu, de même pour l’autre face lorsque les deux faces sont enduites de caoutchouc, ou que le tissu peut être imprégné de caoutchouc lorsque la fluidité du caoutchouc avant vulcanisation et la maille du tissu permettent une telle imprégnation. La présence d’un tel tissu permet de conserver la souplesse et de supprimer voire de réduire l’élasticité, dans ladite au moins une zone déformable. De préférence, la couche de tissu est choisie parmi carbone, le verre, l’aramide, le polyéthylène, le polyamide, le polyester, le coton et le lin, d’autres matières demeurant utilisables dans le cadre de l’invention, selon la destination de l’objet et les conditions d’usage de celui-ci.According to one embodiment of the object, the second thickness of material comprises a fabric coated with rubber. The term “rubber coating” means the fact that the fabric can be coated on one of its two faces or on each of its two faces with rubber, in which case a layer of rubber is deposited on one face of the fabric layer, the same applies to the other side when both sides are coated with rubber, or when the fabric can be impregnated with rubber when the fluidity of the rubber before vulcanization and the mesh of the fabric allow such impregnation. The presence of such a fabric makes it possible to retain the flexibility and to eliminate or even reduce the elasticity, in said at least one deformable zone. Preferably, the fabric layer is chosen from carbon, glass, aramid, polyethylene, polyamide, polyester, cotton and linen, other materials remaining usable in the context of the invention, according to the destination of the object and the conditions of use thereof.
Selon une réalisation de l’objet, la résine non réticulée est choisie parmi une résine époxy, une résine polyester et une résine phénolique. D’autres résines non réticulées restent utilisables dans le cadre de l’invention.According to one embodiment of the object, the non-crosslinked resin is chosen from an epoxy resin, a polyester resin and a phenolic resin. Other non-crosslinked resins can still be used within the scope of the invention.
Tel qu’évoqué précédemment, l’invention trouve son application pour une multitude d’objets présentant une zone déformable destinée à être sollicitée (travailler) durant l’usage. ainsi, par exemple, l’objet selon l’invention peut correspondre à une partie d’aile d’avion avec un volet, les zones déformables étant alors mises en œuvre entre le corps de ladite partie d’aile d’avion et le volet. On entend par volet un spoiler, un aérofrein ou un aileron que l’on peut trouver sur une aile d’avion, selon le type d’avion, comme cela est déjà connu sur les avions traditionnels, voire également un foil de bateau. L’objet peut aussi correspondre à un aileron de voiture avec un volet, ledit volet étant réglable en fonction de la vitesse de la voiture de sorte à la maintenir convenablement plaquée au sol, les zones déformables étant alors mises en œuvre entre le corps de l’aileron et le volet. L’objet peut aussi correspondre à une montre avec un bracelet articulé, le corps de montre et le bracelet formant une seule pièce composite, deux zones déformables étant présentes entre le corps et les deux parties du bracelet. L’objet peut aussi correspondre à un portefeuille avec au moins deux volets articulés et rabattables l’un contre l’autre, une zone déformable étant mise en œuvre entre les deux volets. L’objet peut aussi correspondre à un doigt de robot articulé, lequel peut présenter une phalange distale, une phalange intermédiaire et une phalange proximale, reliées entre elles par des zones déformables. L’objet peut aussi correspondre à une partie d’aile d’avion avec des brise-glaces pour le dégivrage de l’aile d’avion, les brise-glaces étant mis en œuvre par des zones déformables gonflables, le gonflage des zones déformables permettant de briser la glace se formant sur l’aile d’avion durant le vol. L’objet peut aussi correspondre à une porte articulée sur une structure, par exemple un véhicule de type voiture, avion ou hélicoptère, voire d’autres aéronefs, la zone déformable constituant une charnière entre la porte et la structure. L’objet peut également correspondre à un assemblage de wagons articulés entre eux grâce à des zones déformables formées entre lesdits wagons.As mentioned previously, the invention finds its application for a multitude of objects having a deformable zone intended to be stressed (work) during use. thus, for example, the object according to the invention may correspond to a part of an airplane wing with a flap, the deformable zones then being implemented between the body of said part of the airplane wing and the flap . By flap is meant a spoiler, an airbrake or an aileron that can be found on an aircraft wing, depending on the type of aircraft, as is already known on traditional aircraft, or even a boat foil. The object can also correspond to a car spoiler with a flap, said flap being adjustable according to the speed of the car so as to keep it suitably flat on the ground, the deformable zones then being implemented between the body of the aileron and flap. The object can also correspond to a watch with an articulated bracelet, the watch body and the bracelet forming a single composite part, two deformable zones being present between the body and the two parts of the bracelet. The object can also correspond to a wallet with at least two hinged and folding flaps against each other, a deformable zone being implemented between the two flaps. The object may also correspond to an articulated robot finger, which may have a distal phalanx, an intermediate phalanx and a proximal phalanx, interconnected by deformable zones. The object may also correspond to part of an airplane wing with icebreakers for de-icing the airplane wing, the icebreakers being implemented by inflatable deformable zones, the inflation of the deformable zones to break the ice forming on the aircraft wing during flight. The object can also correspond to a door hinged on a structure, for example a vehicle of the car, airplane or helicopter type, or even other aircraft, the deformable zone constituting a hinge between the door and the structure. The object can also correspond to an assembly of wagons articulated together thanks to deformable zones formed between said wagons.
