Description

Arrière-plan de l'inventionBackground of the invention

La présente invention a pour objet un tapis enroulable sur lui-même, configuré pour permettre le passage de véhicules, d'individus ou d'animaux, sur une surface accidentée telle que, par exemple, un chemin sur lequel sont formées des ornières, ou sur un sol boueux, marécageux ou encore sableux.The present invention relates to a self-winding mat configured to allow the passage of vehicles, individuals or animals on a rough surface such as, for example, a path on which are formed ruts, or on muddy, swampy or sandy soil.

Elle trouve en particulier de nombreuses applications dans le domaine humanitaire, en permettant d'accéder à des endroits difficiles, dans le domaine aéroportuaire, en permettant le déplacement au sol d'un avion, ou l'atterrissage d'un aéronef sur un terrain accidenté, ou sur un terrain meuble, sans que l'aéronef ne risque de s'enliser, ou dans tout autre domaine pouvant nécessiter le passage de véhicules, d'individus ou d'animaux sur un terrain accidenté et/ou instable.In particular, it finds many applications in the humanitarian field, by providing access to difficult locations in the airport field, by allowing the ground clearance of an aircraft, or the landing of an aircraft on rough terrain. , or on soft ground, without the aircraft being in danger of becoming bogged down, or in any other area that may require the passage of vehicles, individuals or animals over rough and / or unstable terrain.

Différents types de revêtements de surface configurés pour permettre une circulation sur de tels terrains accidentés sont connus de l'art antérieur.Different types of surface coatings configured to allow circulation on such uneven ground are known from the prior art.

On connaît par exemple des revêtements constitués par des lames métalliques parallèles et articulées entre elles.For example, coatings consisting of parallel metal blades and articulated between them are known.

Néanmoins, ces produits, pour être résistants de manière à pouvoir supporter le passage, par exemple, de véhicules, sont généralement lourds. En outre, ils sont habituellement encombrants, de sorte qu'ils occupent un espace significatif lorsqu'ils ne sont pas utilisés. Par ailleurs, leur production est généralement fastidieuse et coûteuse, du fait des matériaux utilisés et de leurs dimensions.Nevertheless, these products, to be resistant so as to be able to withstand the passage of, for example, vehicles, are generally heavy. In addition, they are usually bulky, so that they occupy significant space when not in use. Moreover, their production is generally tedious and expensive, because of the materials used and their dimensions.

On connaît aussi du document FR 2 976 598 , déposé par la demanderesse, un tapis constitué par la superposition d'un premier et d'un second plis enduits de couches en élastomère. Ce tapis présente une direction longitudinale et une direction transversale, et comporte une première et une deuxième poches s'étendant selon la direction transversale du tapis, chacune des première et deuxième poches étant définie entre au moins une première portion et une seconde portion fixée à la première portion, les premières portions des première et deuxième poches, d'une part, et les secondes portions des première et deuxième poches, d'autre part, formant respectivement les premier et second plis.Document is also known FR 2,976,598 , filed by the applicant, a carpet constituted by the superposition of a first and a second ply coated with elastomeric layers. This mat has a longitudinal direction and a transverse direction, and has first and second pockets extending in the transverse direction of the belt, each of the first and second pockets being defined between at least a first portion and a second portion attached to the first portion, the first portions of the first and second pockets, on the one hand, and the second portions of the first and second pockets, on the other hand, forming respectively the first and second folds.

Objet et résumé de l'inventionObject and summary of the invention

La présente invention a pour but de résoudre, parmi d'autres, les insuffisances décrites plus haut des revêtements connus, en proposant un tapis enroulable sur lui-même, résistant et occupant un espace limité, lorsqu'il n'est pas utilisé, pour permettre, lorsqu'il est déroulé, le passage sur une surface accidentée.The present invention aims to solve, among others, the shortcomings described above known coatings, by providing a self-winding mat, resistant and occupying a limited space, when not in use, for allow, when unrolled, the passage over a rough surface.

Ce but est atteint par le fait que l'invention porte sur un tapis enroulable sur lui-même dans lequel la première portion de chaque poche présente un bord latéral d'extrémité libre disposé en regard de l'autre poche et s'étendant selon la direction transversale du tapis, le bord latéral d'extrémité libre de la première portion de la première poche étant distant et distinct du bord latéral d'extrémité libre de la première portion de la deuxième poche.This object is achieved by the fact that the invention relates to a self-winding carpet in which the first portion of each pocket has a free end lateral edge arranged facing the other pocket and extending according to the transverse direction of the belt, the free end lateral edge of the first portion of the first pocket being remote and distinct from the free end lateral edge of the first portion of the second pocket.

Par cette disposition, le tapis peut aisément être enroulé sur lui-même, pour présenter un encombrement limité lorsqu'il n'est pas utilisé. Par ailleurs, le poids et le coût de fabrication du tapis sont ainsi réduits, par rapport à un tapis dont les premières portions des première et deuxième poches forment une seule et même pièce.By this arrangement, the carpet can easily be wound on itself, to present a limited space when not in use. Moreover, the weight and the manufacturing cost of the carpet are thus reduced, compared to a carpet whose first portions of the first and second pockets form a single piece.

Les poches sont configurées pour recevoir un dispositif de rigidification, de manière à augmenter la motricité et la portance de la surface lorsque le tapis est positionné sur ladite surface accidentée.The pockets are configured to receive a stiffening device, so as to increase the traction and lift of the surface when the mat is positioned on said rough surface.

De préférence, les poches sont traversantes, pour permettre l'insertion et le retrait de dispositifs de rigidification.Preferably, the pockets are through, to allow insertion and removal of stiffening devices.

L'invention est déclinée ci-après dans une série de variantes de réalisation, qui peuvent être considérées seules ou en combinaison avec une ou plusieurs des précédentes.The invention is described below in a series of alternative embodiments, which may be considered alone or in combination with one or more of the previous ones.

Avantageusement, l'une des premières et secondes portions comporte un pli textile.Advantageously, one of the first and second portions comprises a textile ply.

De manière avantageuse, le pli textile est tissé.Advantageously, the textile ply is woven.

Par cette disposition, la flexibilité du tapis est permise, sans compromettre sa résistance.By this arrangement, the flexibility of the carpet is allowed, without compromising its resistance.

De préférence, au moins l'une des premières et secondes portions comporte une première face couverte d'une couche de polymère.Preferably, at least one of the first and second portions comprises a first face covered with a polymer layer.

Avantageusement, le polymère est un élastomère ; on peut également prévoir la présence, sur la première face, voire sur les deux faces, de l'une et/ou l'autre des premières et secondes portions, de tout autre matériau, tel que du caoutchouc, présentant des propriétés d'allongement à la rupture et d'adhérence intéressantes, les deux faces pouvant être couvertes de deux matériaux distincts ou identiques.Advantageously, the polymer is an elastomer; one can also predict the presence, on the first face, or both sides, of one and / or the other of the first and second portions, of any another material, such as rubber, having desirable elongation at break and adhesion properties, both faces being able to be covered with two different or identical materials.

Ainsi, la résistance du tapis est encore améliorée ; en outre, le tapis offre par cette caractéristique un coefficient d'adhérence satisfaisant entre, d'une part, les moyens de déplacement du véhicule ou de l'individu circulant sur le tapis, et, d'autre part, le tapis et la surface sur laquelle il est disposé.Thus, the resistance of the carpet is further improved; in addition, the carpet offers, by this characteristic, a satisfactory coefficient of adhesion between, on the one hand, the means of movement of the vehicle or the individual traveling on the carpet, and, on the other hand, the carpet and the surface on which he is disposed.

De manière avantageuse, selon un premier mode de réalisation, la seconde portion de la première poche et la seconde portion de la deuxième poche constituent une seule et même pièce qui s'étend entre les première et deuxième poches.Advantageously, according to a first embodiment, the second portion of the first pocket and the second portion of the second pocket constitute a single piece which extends between the first and second pockets.

Par cette disposition, la fabrication du tapis est simplifiée, les premières portions des première et deuxième poches étant disposées sur, et fixées à, la pièce constituée par les secondes portions des première et deuxième poches.By this arrangement, the manufacture of the carpet is simplified, the first portions of the first and second pockets being arranged on and fixed to the part constituted by the second portions of the first and second pockets.

Les deux faces peuvent être couvertes de deux matériaux distincts ou identiquesPreferably, the polymer is an elastomer; it is also possible to provide, on the first face of the part, or on both sides, of any other material, such as rubber, having desirable properties of elongation at break and adhesion. Both sides can be covered with two different or identical materials

Avantageusement, selon un deuxième mode de réalisation, la seconde portion de chaque poche présente un bord latéral d'extrémité libre disposé en regard de l'autre poche et s'étendant selon la direction transversale du tapis, le bord latéral d'extrémité libre de la seconde portion de la première poche étant distant et distinct du bord latéral d'extrémité libre de la seconde portion de la deuxième poche.Advantageously, according to a second embodiment, the second portion of each pocket has a free end lateral edge arranged facing the other pocket and extending in the transverse direction of the belt, the free end lateral edge of the second portion of the first pocket being remote and distinct from the free end lateral edge of the second portion of the second pocket.

Par cette disposition, le poids du tapis est encore réduit, sa flexibilité est améliorée et, par suite, l'encombrement occupé par le tapis lorsqu'il n'est pas utilisé est également réduit.By this arrangement, the weight of the carpet is further reduced, its flexibility is improved and, as a result, the space occupied by the carpet when not in use is also reduced.

De manière avantageuse, les première et seconde portions de la première poche comportent une première face couverte d'une couche de polymère, les bords latéraux d'extrémité libres des première et seconde portions étant fixés ensemble.Advantageously, the first and second portions of the first pocket comprise a first face covered with a polymer layer, the free end lateral edges of the first and second portions being fixed together.

De préférence, les bords latéraux d'extrémité libres des première et seconde portions sont vulcanisés ensemble. La fixation peut également être réalisée, par exemple, par collage, soudage ou tout autre moyen mécanique.Preferably, the free end side edges of the first and second portions are vulcanized together. The attachment can also be made, for example, by gluing, welding or any other mechanical means.

Ainsi, les première et deuxième poches sont solidement formées, et leur résistance est augmentée.Thus, the first and second pockets are solidly formed, and their strength is increased.

Avantageusement, le tapis comporte un élément de jonction reliant la première poche à la deuxième poche, ledit élément de jonction étant fixé aux bords latéraux d'extrémité libres des premières portions des première et deuxième poches.Advantageously, the belt comprises a connecting element connecting the first pocket to the second pocket, said connecting element being attached to the free end lateral edges of the first portions of the first and second pockets.

Par cette disposition, des matériaux différents peuvent être utilisés, d'une part pour former l'élément de jonction, d'autre part pour former les première et seconde portions définissant les première et deuxième poches. Le tapis peut ainsi présenter des caractéristiques de résistance et de flexibilité ajustées aux sollicitations subies par ses différentes parties.By this arrangement, different materials can be used, on the one hand to form the joining element, on the other hand to form the first and second portions defining the first and second pockets. The carpet can thus have characteristics of strength and flexibility adjusted to the stresses experienced by its different parts.

De manière avantageuse, l'élément de jonction comporte un pli textile.Advantageously, the joining element comprises a textile ply.

De préférence, l'élément de jonction comporte un pli tissé ; il peut également comporter tout autre matériau, tel qu'une plaque métallique, une plaque en matériau composite, une grille pouvant présenter des propriétés de rigidité adaptées à l'usage du tapis, ...Preferably, the joining element comprises a woven fold; it may also include any other material, such as a metal plate, a composite material plate, a grid that may have rigidity properties suitable for the use of the carpet, etc.

L'élément de jonction peut ainsi être adapté à l'usage auquel le tapis est destiné, les conditions de son utilisation pouvant requérir des propriétés spécifiques de l'élément de jonction.The joining element can thus be adapted to the use for which the carpet is intended, the conditions of its use may require specific properties of the connecting element.

Avantageusement, l'élément de jonction comporte au moins une perforation.Advantageously, the joining element comprises at least one perforation.

De préférence, l'élément de jonction comporte une pluralité de perforations.Preferably, the joining element comprises a plurality of perforations.

Par cette disposition, en particulier lorsque le tapis est utilisé en milieu humide, il ne risque pas d'être détérioré par un liquide, tel que de l'eau, qui stagnerait sur l'élément de jonction lors de son utilisation. L'eau peut ainsi s'écouler au travers des perforations. La présence de la perforation permet également de faciliter le rangement du tapis, lorsqu'il n'est pas utilisé, en favorisant l'expulsion d'un matériau meuble, tel que du sable ou de la terre, qui recouvrirait l'élément de jonction suite à son utilisation.By this arrangement, particularly when the carpet is used in a humid environment, it is not likely to be damaged by a liquid, such as water, which would stagnate on the connecting element during use. Water can flow through the perforations. The presence of perforation also facilitates the storage of the carpet, when not in use, by promoting the expulsion of a loose material, such as sand or earth, which would cover the joining element following its use .

De manière avantageuse, l'élément de jonction comporte une première face couverte d'une couche de polymère.Advantageously, the junction element comprises a first face covered with a polymer layer.

Avantageusement, le polymère est un élastomère ; on peut également prévoir la présence, sur la première face de l'élément de jonction, voire sur ses deux faces, de tout autre matériau, tel que du caoutchouc, présentant des propriétés d'allongement à la rupture et d'adhérence intéressantes. Les deux faces peuvent être couvertes de deux matériaux distincts ou identiquesAdvantageously, the polymer is an elastomer; it is also possible to provide, on the first face of the joining element, or on both its faces, any other material, such as rubber, having desirable properties of elongation at break and adhesion. Both sides can be covered with two different or identical materials

De manière avantageuse, l'élément de jonction présente une bordure d'extrémité prise en sandwich entre les première et seconde portions de la première poche.Advantageously, the joining element has an end edge sandwiched between the first and second portions of the first pocket.

Par cette disposition, l'élément de jonction est fixé de manière solide à la première poche, la liaison entre la première poche et l'élément de jonction ne constituant pas une zone de fragilité qui pourrait compromettre la résistance globale du tapis.By this arrangement, the connecting element is firmly attached to the first pocket, the connection between the first pocket and the connecting element not constituting a zone of weakness that could compromise the overall strength of the carpet.

De préférence, les première et seconde portions de la première poche comportent une première face couverte d'une couche de polymère, l'élément de jonction et les première et seconde portions de la première poche étant vulcanisés ensemble.Preferably, the first and second portions of the first pocket comprise a first face covered with a polymer layer, the joining element and the first and second portions of the first pocket being vulcanized together.

La vulcanisation permet encore d'améliorer la solidité de la fixation de l'élément de jonction à la première poche ; on peut également utiliser tout autre procédé de fixation, tel que le collage, le soudage ou tout autre moyen mécanique.The vulcanization further improves the strength of the fastening of the connecting element to the first pocket; it is also possible to use any other fixing method, such as gluing, welding or any other mechanical means.

Avantageusement, le tapis comporte une première face couverte d'une couche de polymère.Advantageously, the carpet comprises a first face covered with a polymer layer.

De manière avantageuse, le polymère est un élastomère ; on peut également prévoir la présence, sur la première face du tapis, voire sur ses deux faces, de tout autre matériau, tel que du caoutchouc, présentant des propriétés d'allongement à la rupture et d'adhérence intéressantes. Les deux faces peuvent être couvertes de deux matériaux distincts ou identiquesAdvantageously, the polymer is an elastomer; it is also possible to provide the presence, on the first face of the carpet, or on both sides, of any other material, such as rubber, having desirable properties of elongation at break and adhesion. Both sides can be covered with two different or identical materials

De préférence, la première portion de la première poche s'étend sur tout ou partie de la largeur du tapis.Preferably, the first portion of the first pocket extends over all or part of the width of the carpet.

Par cette disposition, le maintien d'un dispositif de rigidification dans la poche est assuré, le dispositif de rigidification ne risquant pas de s'échapper accidentellement de la poche lors de l'utilisation du tapis.By this arrangement, the maintenance of a stiffening device in the pocket is ensured, the stiffening device is not likely to escape accidentally from the pocket when using the carpet.

Avantageusement, la première portion de la première poche est constituée d'une pluralité d'éléments de fourreau distants les uns des autres.Advantageously, the first portion of the first pocket consists of a plurality of sleeve elements spaced from each other.

Ainsi, la quantité de matière nécessaire à la formation de la première poche peut être limitée, permettant par là même de réduire le poids du tapis. En outre, la présence d'espaces entre les éléments de fourreau consécutifs permet également de faciliter l'engagement d'un dispositif de rigidification dans la poche, et d'en faciliter le retrait, l'utilisateur pouvant guider le déplacement du dispositif de rigidification au travers de ces espaces.Thus, the amount of material needed to form the first pocket can be limited, thereby reducing the weight of the carpet. In addition, the presence of spaces between the consecutive sheath elements also facilitates the engagement of a stiffening device in the pocket, and to facilitate removal, the user can guide the movement of the stiffening device through these spaces.

De manière avantageuse, considérée selon la direction longitudinale du tapis, la distance séparant les première et deuxième poches est supérieure à la largeur de la première portion de la première poche.Advantageously, considered in the longitudinal direction of the belt, the distance between the first and second pockets is greater than the width of the first portion of the first pocket.

Ainsi, l'enroulement du tapis sur lui-même est facilité, permettant ainsi de limiter l'encombrement du dispositif lorsqu'il n'est pas utilisé.Thus, the winding of the carpet on itself is facilitated, thereby limiting the size of the device when not in use.

De préférence, le tapis comporte en outre au moins un dispositif de rigidification inséré dans chacune des première et deuxième poches.Preferably, the carpet further comprises at least one stiffening device inserted into each of the first and second pockets.

La présence du dispositif de rigidification permet ainsi d'améliorer la portance du tapis, lorsqu'il est disposé sur une surface meuble ou accidentée.The presence of the stiffening device thus makes it possible to improve the lift of the carpet, when it is placed on a loose or uneven surface.

Description détaillée de l'inventionDetailed description of the invention

Les figures 1A et 1B représentent un premier mode de réalisation d'un tapis 10 selon la présente invention.The Figures 1A and 1B represent a first embodiment of a belt 10 according to the present invention.

Le tapis 10 a une direction longitudinale L et une direction transversale T. Le tapis 10 comporte également une première 12 et une seconde 14 faces opposées l'une à l'autre.The belt 10 has a longitudinal direction L and a transverse direction T. The belt 10 also has a first 12 and a second face 14 opposite to each other.

Le tapis 10 présente une pluralité de poches 20, 20', 20" s'étendant selon la direction transversale T du tapis 10. The belt 10 has a plurality of pockets 20, 20 ', 20 " extending in the transverse direction T of the belt 10.

Par exemple, et de manière non limitative, les poches 20, 20', 20" sont traversantes, et configurées de manière à recevoir un dispositif de rigidification 21, 21', 21" ; les dispositifs de rigidification 21, 21', 21" sont, par exemple, de forme cylindrique et peuvent être formés dans un matériau résistant, tel qu'un matériau composite, de l'acier, du bois, ...For example, and without limitation, the pockets 20, 20 ', 20 " are through, and configured to receive a stiffening device 21, 21', 21"; the stiffening devices 21, 21 ', 21 " are, for example, of cylindrical shape and can be formed in a resistant material, such as a composite material, steel, wood, etc.

Chacune des poches 20, 20', 20" est définie entre une première portion 22, 22', 22" et une seconde portion 28, 28', 28" fixées l'une à l'autre en délimitant un volume intérieur.Each of the pockets 20, 20 ', 20 " is defined between a first portion 22, 22', 22" and a second portion 28, 28 ', 28 " fixed to one another by delimiting an interior volume.

Les premières portions 22, 22', 22" présentent chacune un premier 24, 24', 24" et un second 26, 26', 26" bords latéraux d'extrémité libres.The first portions 22, 22 ', 22 " each have a first 24, 24', 24" and a second 26, 26 ', 26 " free end side edges.

Par exemple et de manière non limitative, les bords latéraux d'extrémité libres 24, 24', 24", 26, 26', 26" sont parallèles les uns aux autres et s'étendent selon la direction transversale T du tapis 10 ; par exemple et de manière non limitative, la direction transversale T est perpendiculaire à la direction longitudinale L du tapis 10. For example and without limitation, the free end side edges 24, 24 ', 24 ", 26, 26', 26" are parallel to each other and extend in the transverse direction T of the belt 10; for example and without limitation, the transverse direction T is perpendicular to the longitudinal direction L of the belt 10.

Tel que cela apparaît, en particulier sur la figure 2 , les bords latéraux d'extrémité libres 26, 24' des premières portions 22, 22' de deux poches consécutives 20, 20', qui sont donc disposés en regard l'un de l'autre, sont distants et distincts.As it appears, especially on the figure 2 , The free end side edges 26, 24 'of the first portions 22, 22' of two consecutive pockets 20, 20 ', which are arranged opposite one another, are distant and distinct.

Les premières portions 22, 22', 22" s'étendent, par exemple et de manière non limitative, sur toute la largeur du tapis 10 ; on pourrait bien évidemment concevoir un tapis 10 dont les premières portions 22, 22', 22" ne s'étendraient que sur une partie de la largeur du tapis 10, sans sortir du cadre de la présente invention.The first portions 22, 22 ', 22 " extend, for example and without limitation, over the entire width of the belt 10, one could of course design a belt 10 whose first portions 22, 22', 22" do not would extend only over a portion of the width of the belt 10, without departing from the scope of the present invention.

Par exemple, les premières portions 22, 22', 22" comportent un pli textile, tel qu'un tissu ; elles peuvent également, de manière alternative ou en combinaison avec un pli textile, comporter une couche de polymère disposée sur l'une et/ou l'autre de leurs faces.For example, the first portions 22, 22 ', 22 " comprise a textile ply, such as a fabric, they may also, alternatively or in combination with a textile ply, comprise a layer of polymer disposed on one and / or the other of their faces.

On peut également concevoir un tapis 10 dont les premières portions 22, 22', 22" comportent, de manière alternative ou en combinaison avec les éléments précédents, une feuille de matériau, tel que du polymère.It is also conceivable a belt 10 whose first portions 22, 22 ', 22 " comprise, alternatively or in combination with the previous elements, a sheet of material, such as polymer.

Dans le mode de réalisation du tapis 10 représenté en particulier par les figures 1A, 1B et 2 , les secondes portions 28, 28', 28" des poches 20, 20', 20" constituent une seule et même pièce 34 qui s'étend entre les différentes poches 20, 20', 20". In the embodiment of the belt 10 shown in particular by the Figures 1A, 1B and 2 , The second portions 28, 28 ', 28 "of the pockets 20, 20', 20" form a single piece 34 which extends between the various pockets 20, 20 ', 20 ".

Par exemple et de manière non limitative, la pièce 34 comporte un pli textile ; on peut également concevoir un tapis 10 dont l'une ou l'autre des faces de la pièce 34 est couverte d'une couche de matériau, tel que du polymère.For example and without limitation, the part 34 comprises a textile ply; it is also conceivable a carpet 10 , one or the other of the faces of the part 34 is covered with a layer of material, such as polymer.

On comprend donc que les premières portions 22, 22', 22" des poches 20, 20', 20" sont rapportées sur la pièce 34 selon la direction transversale T du tapis 10. It is therefore understood that the first portions 22, 22 ', 22 " of the pockets 20, 20', 20" are attached to the piece 34 in the transverse direction T of the belt 10.

Par exemple et de manière non limitative, les bords latéraux d'extrémité libres 24, 26, 24', 26' des premières portions 22, 22' sont cousus, agrafés, collés ou fixés par tout autre moyen sur la pièce 34 constituée par les secondes portions 28, 28' des poches 20, 20'. For example and without limitation, the free end side edges 24, 26, 24 ', 26' of the first portions 22, 22 ' are sewn, stapled, glued or fixed by any other means on the piece 34 constituted by the second portions 28, 28 ' of the pockets 20, 20'.

Dans l'hypothèse où les premières portions 22, 22' et la pièce 34 comportent au moins une couche de polymère sur leurs faces disposées en regard l'une de l'autre, on peut également concevoir un tapis 10 dont les bords latéraux d'extrémité libres 24, 26, 24', 26' des premières portions 22, 22' sont vulcanisés sur la pièce 34. In the event that the first portions 22, 22 ' and the piece 34 comprise at least one layer of polymer on their faces disposed facing each other, it is also possible to design a mat 10 whose lateral edges of free end 24, 26, 24 ', 26' of the first portions 22, 22 ' are vulcanized on the piece 34.

Tel que cela apparaît sur la figure 2 , on constate que, lorsque le tapis 10 est considéré selon une coupe longitudinale, les poches 20, 20', 20" sont formées par au moins deux couches distinctes constituées respectivement par les premières 22, 22' et secondes 28, 28' portions, alors que la partie s'étendant entre deux poches consécutives 20, 20' présente un nombre strictement inférieur de couches ; en l'espèce, les poches 20, 20' sont constituées par la superposition de deux couches, alors que la partie s'étendant entre deux poches consécutives 20, 20' comporte une unique couche.As it appears on the figure 2 , It is observed that when the mat 10 is seen in longitudinal section, the pockets 20, 20 ', 20 "are formed by at least two separate layers respectively constituted by the first 22, 22' and second 28, 28 'portions, while the portion extending between two consecutive pockets 20, 20 ' has a strictly lower number of layers, in this case, the pockets 20, 20' are constituted by the superposition of two layers, while the portion extending between two consecutive pockets 20, 20 ' comprises a single layer.

Par ces dispositions, outre le gain de matière significative qu'une telle caractéristique permet de réaliser, le tapis 10, tel que représenté en particulier sur la figure 1B , peut être plus facilement enroulé sur lui-même, de manière par exemple, à en réduire l'encombrement lorsqu'il n'est pas utilisé. Les barres de rigidification 21, 21',21" peuvent alternativement être maintenues dans les poches 20, 20', 20" lorsque le tapis est replié sur lui-même, ou être insérées dans les poches 20, 20', 20" après que le tapis 10 a été déplié, tel que représenté sur la figure 1A . By these provisions, in addition to the significant material gain that such a characteristic makes it possible to achieve, the belt 10, as represented in particular on the Figure 1B Can be more easily wound on itself, so for example, to reduce clutter when not in use. The stiffening bars 21, 21 ', 21 " may alternatively be held in the pockets 20, 20', 20" when the carpet is folded on itself, or inserted into the pockets 20, 20 ', 20 " after the belt 10 has been unfolded, as shown on the Figure 1A .

Par exemple et de manière non limitative, tel que représenté sur la figure 3 , une ou plusieurs couches 36, 38 de matériau supplémentaires, tel que du polymère, peuvent être disposées sur l'une ou l'autre des première 12 et seconde 14 faces du tapis 10 ; l'ajout de telles couches de matériau permet ainsi de renforcer le tapis 10, sans en compromettre la flexibilité. En outre, la présence de tels matériaux sur les faces 12, 14 du tapis 10 permet la formation d'empreintes, permettant d'améliorer encore la motricité et la portance de la surface sur laquelle le tapis 10 est destiné à être disposé.For example and in a nonlimiting manner, as represented on the figure 3 , One or more layers 36, 38 additional material such as the polymer, may be disposed on one or the other of the first 12 and second 14 faces of the belt 10; the addition of such layers of material thus reinforces the belt 10, without compromising flexibility. In addition, the presence of such materials on the faces 12, 14 of the belt 10 allows the formation of fingerprints, to further improve the motor and the lift of the surface on which the belt 10 is intended to be arranged.

Par exemple et de manière non limitative, les couches de matériau 36, 38 sont collées ou vulcanisées sur les faces 12, 14 du tapis 10. For example and without limitation, the material layers 36, 38 are glued or vulcanized on the faces 12, 14 of the belt 10.

La figure 4 représente une autre variante de réalisation du tapis 10 selon la présente invention.The figure 4 represents another variant embodiment of the belt 10 according to the present invention.

Dans cette variante, les premières portions 22, 22', 22" des poches 20, 20', 20" sont constituées d'une pluralité d'éléments de fourreau 23, 23', 23", les éléments de fourreau 23, 23', 23" étant fixés, par exemple soudés, collés ou vulcanisés, sur la pièce 34. In this variant, the first portions 22, 22 ', 22 " of the pockets 20, 20', 20" consist of a plurality of sheath elements 23, 23 ', 23 ", the sheath elements 23, 23' , 23 "being fixed, for example welded, glued or vulcanized, on the piece 34.

Cette variante permet encore de réduire la quantité de manière nécessaire à la fabrication du tapis 10 ; elle présente en outre l'avantage, par la présence d'un espace entre deux éléments de fourreau 23, 23', 23" consécutifs d'une première portion 22, 22', 22", de faciliter l'introduction et le retrait des dispositifs de rigidification 21, 21', 21" dans les poches 20, 20', 20". This variant also makes it possible to reduce the quantity necessary for the production of the belt 10; it also has the advantage, by the presence of a space between two sheath members 23, 23 ', 23 " consecutive of a first portion 22, 22', 22", to facilitate the introduction and withdrawal of stiffening devices 21, 21 ', 21 " in the pockets 20, 20', 20".

Les figures 5A et 5B représentent schématiquement un deuxième mode de réalisation de tapis 110 selon la présente invention.The Figures 5A and 5B schematically represent a second embodiment of carpet 110 according to the present invention.

De manière similaire au premier mode de réalisation décrit précédemment en référence aux figures 1 à 4 , le tapis 110 a une direction longitudinale L et une direction transversale T. Similarly to the first embodiment described above with reference to the Figures 1 to 4 , the belt 110 has a longitudinal direction L and a transverse direction T.

Il comporte également une pluralité de poches 120, 120', 120" dans lesquelles peuvent être introduits des dispositifs de rigidification 121, 121', 121". It also comprises a plurality of pockets 120, 120 ', 120 " into which stiffening devices 121, 121', 121" can be introduced .

Par ailleurs, les poches 120, 120', 120" sont également définies entre des premières portions 122, 122', 122" et des secondes portions 128, 128', 128" ; les premières portions 122, 122', 122" présentent chacune deux bords latéraux d'extrémité libres 124, 126, 124', 126', les bords latéraux d'extrémité libres 126, 124' de poches consécutives 120, 120' disposés en regard l'un de l'autre étant également, de manière similaire au premier mode de réalisation, distants et distincts l'un de l'autre.On the other hand, the pockets 120, 120 ', 120 " are also defined between first portions 122, 122', 122" and second portions 128, 128 ', 128 ", the first portions 122, 122', 122" each presenting two free end lateral edges 124, 126, 124 ', 126', the free end lateral edges 126, 124 ' of consecutive pockets 120, 120' disposed facing each other also being similar to the first embodiment, remote and distinct from each other.

Par ailleurs, les secondes portions 128, 128', 128" des poches 120, 120', 120" comportent également des bords latéraux d'extrémité libres 130, 130', 132, 132', les bords latéraux d'extrémité libres 132, 130' de deux poches consécutives 120, 120' disposés en regard l'un de l'autre étant également distants et distincts l'un de l'autre.On the other hand, the second portions 128, 128 ', 128 " of the pockets 120, 120', 120" also have free end lateral edges 130, 130 ', 132, 132', the free end lateral edges 132, 130 ' of two consecutive pockets 120, 120' arranged opposite one another are also distant and distinct from each other.

Tel que cela apparaît en particulier sur la figure 5A , qui représente une vue partiellement éclatée du tapis 110, les bords latéraux d'extrémité libres 124, 126, 124', 126', 130, 132, 130', 132' sont fixés ensemble par des moyens mécaniques de fixation ; par exemple et de manière non limitative, les bords latéraux d'extrémité libres sont cousus, collés ou agrafés ensemble.As it appears in particular on the Figure 5A , which shows a partially exploded view of the belt 110, the free end lateral edges 124, 126, 124 ', 126', 130, 132, 130 ', 132' are fixed together by mechanical fastening means; for example and without limitation, the free end side edges are sewn, glued or stapled together.

Par exemple et de manière non limitative, les premières et secondes portions 122, 122', 128, 128' comportent un pli textile ; elles peuvent également être couvertes d'une couche de polymère, sur l'une et/ou l'autre de leurs faces, la présence d'une couche de polymère permettant alors aux bords latéraux d'extrémité libres d'être vulcanisés ensemble pour former les poches 120, 120'. For example and without limitation, the first and second portions 122, 122 ', 128, 128' comprise a textile ply; they can also be covered with a layer of polymer, on one and / or the other of their faces, the presence of a polymer layer then allowing the free end side edges to be vulcanized together to form the pockets 120, 120 '.

Par ailleurs, le tapis 110 comporte une pluralité d'éléments de jonction 140, 140', 140", qui relient les poches 120, 120', 120" consécutives.Furthermore, the carpet 110 has a plurality of junction elements 140, 140 ', 140 ", which connect the pockets 120, 120', 120" consecutive.

Par exemple et de manière non limitative, les éléments de jonction 140, 140', 140" comportent un pli textile, tel que du tissu ; ils peuvent également comporter au moins une perforation permettant ainsi l'évacuation de matériau, tel que de l'eau ou du sable, qui se trouverait sur l'élément de jonction 140, 140', 140". For example and in a nonlimiting manner, the connecting elements 140, 140 ', 140 " comprise a textile ply, such as fabric, they may also comprise at least one perforation thus allowing the evacuation of material, such as water or sand, which would be on the joining element 140, 140 ', 140 ".

Par exemple et de manière non limitative, les éléments de jonction 140, 140', 140" peuvent comporter une plaque métallique, ou une plaque en matériau composite, une grille ou tout autre élément pouvant être utilisé pour constituer un support permettant de circuler sur des terrains meubles ou accidentés.For example and in a nonlimiting manner, the joining elements 140, 140 ', 140 " may comprise a metal plate, or a plate made of composite material, a grid or any other element that can be used to constitute a support making it possible to circulate on loose or uneven grounds.

Les éléments de jonction 140, 140', 140" présentent une première 142, 142', 142" et une seconde 144, 144', 144" bordures d'extrémité ; ils ont également une première 146, 146', 146" et une seconde 148, 148', 148" faces opposées l'une à l'autre.The junction elements 140, 140 ', 140 " have a first 142, 142', 142" and a second 144, 144 ', 144 " end edges, they also have a first 146, 146', 146" and a second 148, 148 ', 148 " faces opposite one another.

Par exemple et de manière non limitative, l'une ou l'autre des faces 146, 146' ,148 ,148' des éléments de jonction 140, 140' est couverte d'une ou plusieurs couches d'un matériau tel que du polymère.For example and without limitation, one or other of the faces 146, 146 ', 148, 148' of the connecting elements 140, 140 ' is covered with one or more layers of a material such as polymer .

Tel que cela apparaît en particulier à l'observation de la figure 5A , les bordures d'extrémité 142, 142', 144, 144' des éléments de jonction 140, 140' sont prises en sandwich entre les premières et secondes portions 122, 122', 128, 128' des poches 120, 120'. As it appears in particular in the observation of the Figure 5A , The end edges 142, 142 ', 144, 144' of the joining members 140, 140 'are sandwiched between the first and second portions 122, 122', 128, 128 'of the pockets 120, 120'.

Par exemple et de manière non limitative, les bordures d'extrémité des éléments de jonction 140, 140' sont vissées, collées, soudées, ou vulcanisées avec les première et seconde portions des poches 120, 120'. For example and without limitation, the end edges of the connecting elements 140, 140 ' are screwed, glued, welded, or vulcanized with the first and second portions of the pockets 120, 120'.

On pourrait bien évidemment concevoir un tapis 110 dont les premières et secondes portions des poches 120, 120' seraient directement fixées l'une à l'autre, les bordures d'extrémité 142, 142', 144, 144' des éléments de jonction 140, 140' étant alors rapportés sur l'une ou l'autre des faces externes des premières et secondes portions des poches 120, 120'. One could of course design a carpet 110 whose first and second portions of the pockets 120, 120 ' would be directly attached to one another, the end edges 142, 142', 144, 144 ' of the connecting elements 140 , 140 ' then being reported on one or other of the outer faces of the first and second portions of the pockets 120, 120'.

Par face externe des premières et secondes portions, on entend la face opposée à celle disposée en regard de la portion correspondante ; en d'autres termes, il s'agit de la face configurée pour être disposée sur la surface accidentée ou meuble, ou pour être au contact du véhicule ou de l'utilisateur circulant sur le tapis lorsqu'il est déplié.By external face of the first and second portions, we mean the opposite side to that arranged opposite the corresponding portion; in other words, it is the face configured to be disposed on the rugged or loose surface, or to be in contact with the vehicle or the user traveling on the carpet when unfolded.

De manière similaire au premier mode de réalisation décrit précédemment, on constate que, lorsque le tapis 110 est considéré selon sa direction longitudinale L, la partie s'étendant entre deux poches consécutives 120, 120' présente un nombre de couches strictement inférieur à celui présenté par les poches 120, 120', une telle disposition permettant, tel que représenté en particulier sur la figure 5B , de replier le tapis 110 sur lui-même.Similarly to the first embodiment described above, it is found that when the belt 110 is considered in its longitudinal direction L, the portion extending between two consecutive pockets 120, 120 ' has a number of layers strictly less than that presented. by the pockets 120, 120 ', such a provision allowing, as shown in particular on the Figure 5B , Fold the mat 110 on himself.

La figure 6 représente une variante du tapis 110 selon la présente invention, dans laquelle l'élément de jonction 140, reliant les poches 120, 120', présente une pluralité de perforations 150. Ces perforations permettent entre autres d'évacuer un liquide ou un matériau qui stagnerait sur l'une des faces de l'élément de jonction, tout en permettant de réduire le poids du tapis 110. The figure 6 represents a variant of the belt 110 according to the present invention, in which the connecting element 140, connecting the pockets 120, 120 ', has a plurality of perforations 150. These perforations make it possible, among other things, to evacuate a liquid or a material which would stagnate on one of the faces of the connecting element, while allowing to reduce the weight of the carpet 110.

De manière similaire à la variante du tapis 10 représentée sur la figure 3, on peut concevoir un tapis 110 dont l'une ou l'autre de ses faces est couverte par une couche de matériau tel que du polymère, sans sortir du cadre de la présente invention.In a manner similar to the variant of the belt 10 shown in FIG. figure 3 a carpet 110 may be designed, one or the other of its faces is covered by a layer of material such as polymer, without departing from the scope of the present invention.

Tel que représenté en particulier sur les figures 2 et 6 , considérée selon la direction longitudinale L du tapis 10, 110, la distance d séparant des poches 20, 20', 120, 120' consécutives est supérieure à la largeur ℓ des premières portions 22, 22', 122, 122' des mêmes poches 20, 20', 120, 120'. As shown in particular on figures 2 and 6 , considered in the longitudinal direction L of the belt 10, 110, the distance d between consecutive pockets 20, 20 ', 120, 120' is greater than the width ℓ of the first portions 22, 22 ', 122, 122' of the same pockets 20, 20 ', 120, 120'.

On pourrait également concevoir une variante du tapis 110 selon le second mode de réalisation, dans laquelle les premières portions 122, 122' seraient constituées, de manière similaire au tapis 10 représenté sur la figure 4 , d'une pluralité d'éléments de fourreau distants les uns des autres.One could also design a variant of the belt 110 according to the second embodiment, in which the first portions 122, 122 ' would be constituted, in a manner similar to the belt 10 shown in FIG. figure 4 , a plurality of sheath elements spaced from each other.

La description ci-dessus est donnée à titre d'exemple, et n'est donc pas limitative de l'invention.The above description is given by way of example, and is therefore not limiting of the invention.

En particulier, on peut concevoir, sans sortir du cadre de la présente invention, un tapis qui combine ensemble différents matériaux, pour former les premières et secondes portions des poches et, alternativement, la pièce s'étendant entre les poches ou les éléments de jonction reliant deux poches consécutives, de manière à obtenir un tapis enroulable sur lui-même et configuré pour permettre la circulation par exemple de véhicule ou de personnes sur une surface accidentée ou instable. On peut également concevoir un tapis comprenant une superposition de différentes couches de textile, de matériau du type polymère, les unes sur les autres.In particular, it is conceivable, without going outside the scope of the present invention, a carpet which combines together different materials, to form the first and second portions of the pockets and, alternatively, the part extending between the pockets or the connecting elements connecting two consecutive pockets, so as to obtain a mat that is rollable on itself and configured to allow circulation for example vehicle or people on a rough or unstable surface. It is also conceivable a carpet comprising a superposition of different layers of textile, polymer-type material, on top of each other.

On peut tout aussi bien concevoir un tapis constitué par des portions formées à partir des différents modes de réalisation décrites précédemment, et solidarisées ensemble par des moyens de jonction mécanique.It is equally possible to design a carpet consisting of portions formed from the various embodiments described above, and secured together by mechanical joining means.

De la même manière, dans les modes de réalisation décrits précédemment, les poches formées dans le tapis sont traversantes et sont configurées pour recevoir des dispositifs de rigidification de section cylindrique ; on pourrait bien évidemment concevoir, sans sortir du cadre de la présente invention, un tapis dont les extrémités des poches seraient fermées, de manière à maintenir les dispositifs de rigidification en place. Les poches pourraient également être conformées pour recevoir, par exemple et de manière non limitative, des plaques allongées formant dispositifs de rigidification.In the same way, in the embodiments described above, the pockets formed in the belt are through and are configured to receive cylindrical section stiffening devices; it would of course be possible to design, within the scope of the present invention, a belt whose ends of the pockets would be closed, so as to maintain the stiffening devices in place. The pockets could also be shaped to receive, for example and without limitation, elongate plates forming stiffening devices.
