Description

L'invention se rattache au secteur technique de la bagagerie de voyage, de randonnée, scolaire pour le portage et le transport de charges de nature quelconque, mais aussi des porte-bébés, et d'une manière générale tout équipement de portage à dos présentant un harnais s'ajustant sur le porteur.The invention relates to the technical sector of luggage travel, hiking, school for the carrying and transport of loads of any kind, but also baby carriers, and generally any carrying equipment backpacking presenting a harness adjusting on the wearer.

Le document US-A-5284279 décrit un dispositif comportant les caractéristiques du préambule de la revendication 1.The document US Patent 5284279 describes a device comprising the features of the preamble of claim 1.

Dans certaines applications de sacs à dos, il a été proposé des dispositifs de réglage en position de la partie sac, plus ou moins chargée, par rapport à un dos de sac associée avec un harnais de portage et pouvant être réglée ponctuellement et préalablement au port, ou être réglée à distance à l'aide de système de commande à distance. Les équipements proposés sont peu pratiques, complexes à réaliser et coûteux en fabrication.In certain applications of backpacks, it has been proposed adjustment devices in position of the bag portion, more or less loaded, with respect to a bag back associated with a carrying harness and can be adjusted punctually and before the port , or be remotely controlled using remote control system. The equipment offered is impractical, complex to produce and expensive to manufacture.

S'agissant du transport de bagagerie de voyage, il n'existe, à la connaissance du demandeur, aucune possibilité de réglage en position de la charge pour faciliter le confort du porteur. De plus en plus, on utilise des bagages de voyage incorporant des roulettes facilitant le transport avec poignée de préhension escamotable. Il arrive que des bagages de ce type soient agencés avec des bretelles. Les voyageurs peuvent ainsi, dans certaines circonstances d'encombrement, prendre en portage des bagages. Il n'y a aucune possibilité de réglage en position en fonction de la charge.With regard to the transport of travel luggage, there is, to the knowledge of the applicant, no possibility of adjustment in position of the load to facilitate the comfort of the wearer. Increasingly, travel luggage incorporating casters is being used to facilitate transportation with a retractable gripping handle. It happens that baggage of this type are arranged with straps. Travelers can thus, under certain circumstances of congestion, take luggage. There is no possibility of adjustment in position depending on the load.

Cette situation se trouve également pour la bagagerie scolaire, mais aussi pour les porte-bébés.This situation is also found for school baggage, but also for baby carriers.

La démarche du demandeur a donc été de réfléchir à un concept nouveau d'un dispositif de portage à dos d'une charge et de son réglage en position, apte à être mis en oeuvre pour la bagagerie de voyage, de randonnée, scolaire, pour le portage des bébés et, d'une manière générale, pour tout équipement de portage à dos par un individu porteur.The applicant's approach was therefore to reflect on a new concept of a load-carrying device and its adjustment in position, suitable for use in travel, hiking, school, luggage storage. the carrying of babies and, in general, for any backpacking equipment by a carrier individual.

Ainsi, les recherches et études du demandeur ont permis d'aboutir à la réalisation d'un dispositif apte à répondre au problème posé et dans toutes les utilisations potentielles telles que rappelées précédemment.Thus, the research and studies of the applicant have led to the realization of a device capable of responding to the problem and in all potential uses as recalled above.

Ainsi, selon l'invention, le dispositif exige l'utilisation d'un concept commun apte à être solidarisé ensuite sur chaque type de bagage ou support de charge.Thus, according to the invention, the device requires the use of a common concept adapted to be subsequently secured on each type of luggage or load carrier.

Selon une première caractéristique, le dispositif de portage à dos d'une charge et de réglage de sa position du type comprenant une structure de dos sur laquelle est positionné un harnais de portage, est remarquable en ce qu'il comprend deux moyens de commande et réglage en position établis à l'aide de commandes manuelles à distance, autonomes l'un par rapport à l'autre, et autorisant le réglage en position de la structure de dos par rapport au harnais de portage, le premier moyen permettant le relevage de la structure de dos par rapport au harnais, et le second moyen l'abaissement de la structure de dos par rapport au harnais, et en ce que la structure de dos est aménagée pour recevoir une courroie sans fin disposée dans son plan longitudinal médian, ladite courroie étant solidarisée par un brin au harnais de portage et permettant le déplacement relatif de la structure de dos par rapport au harnais par le ou les moyens de commande et réglage en position, et en ce qu'un mécanisme de verrouillage sollicité par le second moyen de commande agit et autorise le blocage en position de la courroie sans fin ou sa libération selon les phases de déplacement souhaitées, et en ce que ledit moyen de commande inclut une sangle dont une extrémité est solidarisée à la courroie de liaison et au harnais et l'autre extrémité est agencée pour constituer la poignée de commande, ladite sangle contournant le mécanisme de verrouillage en prenant appui sur ce dernier et provoquant sa mise en fonctionnement.According to a first feature, the load-carrying and position-adjusting device of the type comprising a back structure on which a carrying harness is positioned is remarkable in that it comprises two control means and adjustment in position established by means of remote manual controls, autonomous relative to each other, and allowing adjustment in position of the back structure relative to the carrying harness, the first means for the lifting of the back structure relative to the harness, and the second means lowering the back structure relative to the harness, and in that the back structure is arranged to receive an endless belt disposed in its median longitudinal plane, said belt being secured by a strand to the carrying harness and allowing relative movement of the back structure relative to the harness by the control means and adjustment in position, and in that a locking mechanism biased by the second control means acts and permits locking in position of the endless belt or its release according to the desired displacement phases, and in that said control means includes a strap of which one end is secured to the connecting belt and to the harness and the other end is arranged to form the control handle, said strap bypassing the locking mechanism by bearing on the latter and causing its operation.

Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant d'une manière non limitative illustrée aux figures des dessins.In order to make the object of the invention more concrete, it is now described in a nonlimiting manner illustrated in the figures of the drawings.

Dans la suite de la description, on décrira le dispositif de portage à dos d'une charge et de son réglage en position dans son principe en faisant référence aux figures 9 à 13. Pour l'identification des applications de portage à dos citées à titre non limitatif et illustrées aux figures 1 à 8, on a représenté par (A) la bagagerie scolaire du type cartable par exemple, par (B) la bagagerie de randonnées du type sac à dos par exemple, par (C) la bagagerie de voyage du type valise à roulettes, par (D) le porte-bébé de randonnée. Dans la suite de la description, on utilisera le terme générique Produit (P) pour identifier les applications précitées. Le dispositif de portage à dos de l'invention requiert que le produit présente une structure de dos (1) conformée solidarisée de toute manière appropriée au Produit par couture ou autrement. La structure de dos (1) est ainsi agencée sur une face pour coopérer avec le dispositif de l'invention, et sur l'autre, la partie Produit. La structure de dos (1) est constituée avec un matériau de garniture rigide ou sous forme d'une coque thermoformée et habillée d'une garniture de recouvrement textile.In the remainder of the description, the device for carrying a load on a load and its adjustment in position in its principle will be described with reference to FIGS. 9 to 13. For the identification of the backhand carrying applications mentioned in FIG. Non-limiting and illustrated in Figures 1 to 8, there is represented by (A) the school baggages of the schoolbag type for example, by (B) the baggage-type hiking baggage storage for example, by (C) the travel luggage of the wheeled suitcase type, by (D) the baby carrier. In the remainder of the description, the generic term Product (P) will be used to identify the aforementioned applications. The backing device of the invention requires that the product has a shaped back structure (1) secured in any manner appropriate to the product by sewing or otherwise. The back structure (1) is thus arranged on one side to cooperate with the device of the invention, and on the other, the product part. The back structure (1) is made of a rigid lining material or in the form of a thermoformed shell and covered with a textile covering lining.

De manière connue, la structure de dos du Produit est susceptible de recevoir, sur sa face côté porteur, un harnais (2) de portage équipé de bretelles (2a - 2b) susceptible de permettre le portage. Le positionnement réglable du harnais par rapport à la structure de dos de sac du Produit, étant connu en soi, peut s'effectuer le long de glissières tubulaires (3) ou autres profilés disposés le long de la structure de dos, le harnais présentant des passants de passage le long des dites glissières.In known manner, the back structure of the product is capable of receiving, on its load-bearing side, a harness (2) carrying straps (2a - 2b) capable of carrying. The adjustable positioning of the harness with respect to the backpack structure of the product, being known per se, can be carried out along tubular rails (3) or other sections arranged along the back structure, the harness having passers-by along the said slides.

L'invention vise un dispositif particulier permettant le réglage en position de la structure de dos associée au Produit par rapport au harnais de portage, et ainsi l'aménagement de l'ensemble structure de dos-hamais pour assurer cette fonction. Ledit réglage doit ainsi s'effectuer selon deux mouvements en déplacement de la structure de dos du Produit par rapport au harnais de portage, ce dernier étant à position fixe sur le porteur.The invention relates to a particular device for adjusting the position of the back structure associated with the product relative to the carrying harness, and thus the arrangement of the back-hamais structure assembly to provide this function. Said adjustment must be made in two movements in displacement of the back structure of the product relative to the carrying harness, the latter being in a fixed position on the carrier.

Selon l'invention, le dispositif de réglage du dos de sac par rapport au harnais de portage comprend un premier moyen de réglage (M1) établi à l'aide d'une commande à distance sollicitée manuellement par l'opérateur lui-même. Ce premier moyen permet et a pour fonction essentiellement de provoquer le relevage de la structure de dos associée au Produit par rapport au harnais.According to the invention, the device for adjusting the back of the bag relative to the carrying harness comprises a first adjustment means (M1) established using a remote control manually requested by the operator himself. This first means allows and essentially functions to cause the lifting of the back structure associated with the product relative to the harness.

Il comprend un moyen de traction (4) non élastique dont une première extrémité libre (4a) est située dans la partie basse de la structure de dos associée au Produit, ladite extrémité étant agencée pour constituer un moyen de préhension et de traction sous forme de boucle, poignée et similaire (4b). L'autre extrémité (4c) est fixée directement ou non au harnais (2).It comprises a non-resilient traction means (4) whose first free end (4a) is located in the lower part of the back structure associated with the Product, said end being arranged to constitute a gripping and traction means in the form of loop, handle and the like (4b). The other end (4c) is attached directly or not to the harness (2).

On comprend ainsi que toute traction manuelle par le porteur sur l'extrémité de préhension (4c) du moyen (4) va provoquer le tirage du moyen et ainsi le rapprochement de la partie basse de la structure de dos par rapport à la partie basse du harnais et ainsi le relevage de la structure de dos associée au Produit.It is thus understood that any manual traction by the wearer on the gripping end (4c) of the means (4) will cause the pulling of the means and thus the approximation of the lower part of the back structure with respect to the lower part of the harness and thus the lifting of the back structure associated with the product.

Le dispositif de l'invention comprend également un moyen (M2) permettant de faire descendre la structure de dos par rapport au harnais et ainsi d'affiner le réglage en position de l'un par rapport à l'autre.The device of the invention also comprises a means (M2) for lowering the back structure relative to the harness and thus refine the adjustment in position of one relative to the other.

Plus spécifiquement, ledit moyen (M2), pris dans son ensemble, comprend un moyen de liaison (5) entre le harnais (2) et la structure de dos (1) permettant le déplacement de l'un par rapport à l'autre, selon les positions de relevage maximum, ou d'abaissement maximum ou des positions intermédiaires, et un second moyen de commande (6) permettant les réglages en positions souhaités.More specifically, said means (M2), taken as a whole, comprises a connecting means (5) between the harness (2) and the back structure (1) allowing the displacement of one relative to the other, according to the maximum lifting position, or maximum lowering position or intermediate positions, and a second control means (6) allowing the adjustments in the desired positions.

Le moyen de liaison (5) est réalisé sous forme d'une courroie sans fin établie en tous matériaux appropriés, cette courroie étant située dans l'axe médian longitudinal de la structure de dos. Cette courroie est maintenue en tension, mais est en libre déroulement et est positionnée par rapport à un premier moyen de renvoi (7) situé fixement dans la partie haute de la structure de dos, et à un second moyen de renvoi (8) situé fixement dans la partie basse de la structure de dos.The connecting means (5) is in the form of an endless belt made of all suitable materials, this belt being located in the longitudinal median axis of the back structure. This belt is maintained in tension, but is free-flowing and is positioned relative to a first return means (7) fixedly located in the upper part of the back structure, and to a second return means (8) located fixedly in the part low back structure.

Dans sa partie inférieure, ladite courroie (5) s'enroule autour d'un axe (8a) d'une attache en boucle, tandis que le second axe (8b) de celle-ci permet l'enroulement d'un passant (9) dont l'extrémité inférieure (9a) est fixée de manière appropriée sur la structure de dos dans sa partie inférieure.In its lower part, said belt (5) wraps around an axis (8a) of a loop fastener, while the second axis (8b) thereof allows the winding of a loop (9). ) whose lower end (9a) is suitably fixed to the back structure in its lower part.

La courroie sans fin de liaison (5) est maintenue en tension supérieure sur l'axe (7a) du moyen de renvoi supérieur (7) et situé entre les ailes (7b) de ce dernier.
La courroie sans fin est disposée d'un seul côté de la structure de dos. Ladite courroie sans fin, est, par l'un de ses brins (7c), solidaire du harnais (2) de portage par un ou plusieurs moyens de liaison (10). On comprend ainsi que le déplacement du harnais par rapport à la structure de dos est étroitement associé au déplacement de ladite courroie sans fin selon une amplitude qui est définie par les parties externes, haute et basse, du harnais par rapport à la structure de dos. Ladite liaison harnais-courroie sans fin est établie par tous moyens appropriés.The endless connecting belt (5) is held in upper tension on the axis (7a) of the upper deflection means (7) and located between the wings (7b) thereof.
The endless belt is arranged on one side of the back structure. Said endless belt is, by one of its strands (7c), integral with the harness (2) portage by one or more connecting means (10). It is thus understood that the movement of the harness relative to the back structure is closely associated with the movement of said endless belt according to an amplitude which is defined by the external parts, high and low, of the harness relative to the back structure. Said harness-endless belt connection is established by any appropriate means.

Le moyen de renvoi (7) comprend une partie chape (7d) avec un axe (7a) sur lequel passe le brin de la courroie (5). La base (7e) du moyen de renvoi supérieur (7) est fixée à la structure de dos (1) par tous moyens appropriés. Le moyen de renvoi (7) inclut un axe (7f) complémentaire sur lequel s'articule un mécanisme de verrouillage (11). Le moyen de renvoi (7) inclut un axe supérieur (7g) entre les ailes (7b) dont la fonction sera précisée par la suite. Le moyen de verrouillage (11) monté pivotant sur l'axe (7f) est agencé avec une forme profilée dentelée (11a) susceptible de venir en contact et pression sur la partie en regard de la courroie sans fin (5). Le moyen de verrouillage (11) présente un prolongement (11b) qui se trouve dans une angulation en V avec la forme dentelée (11a) en étant dans un plan déporté extérieurement par rapport au plan de ladite forme (11a). Un ressort de rappel (12) du type à épingle est monté sur l'axe (7f) et l'une de ses branches (12a) est susceptible de prendre appui sur une paroi d'appui (7h) formée sur le moyen de renvoi (7) et l'autre branche (12b) vient en appui sur la face arrière du prolongement (11b).The return means (7) comprises a clevis portion (7d) with an axis (7a) on which the strand of the belt (5) passes. The base (7e) of the upper return means (7) is fixed to the back structure (1) by any appropriate means. The return means (7) includes a complementary axis (7f) on which a locking mechanism (11) is articulated. The means of return (7) includes an upper axis (7g) between the wings (7b) whose function will be specified later. The locking means (11) pivotally mounted on the axis (7f) is arranged with a serrated profiled shape (11a) capable of coming into contact and pressure on the part opposite the endless belt (5). The locking means (11) has an extension (11b) which is in a V-angulation with the serrated shape (11a) being in a plane offset outwardly with respect to the plane of said shape (11a). A pin-type return spring (12) is mounted on the axis (7f) and one of its branches (12a) is able to bear against a support wall (7h) formed on the return means (7) and the other branch (12b) bears on the rear face of the extension (11b).

Par ailleurs, selon l'invention, le moyen de commande (M2) inclut une sangle (6) dont une extrémité (6a) se trouve solidarisée à la courroie de liaison (5) dans une zone (10) se situant à l'endroit de fixation de ladite courroie (5) avec le harnais (2). Ladite sangle (6), comme il apparaît aux figures 9 à 13, contourne le mécanisme de verrouillage (11) et prend appui sur celui-ci en particulier sur la partie de prolongement (11b) du levier basculant (11). La sangle (6) s'enroule autour de l'axe supérieur (7g) pour être ensuite guidée entre la structure de dos et le brin arrière de la courroie de liaison (5). La sangle (6) présente sur son brin d'extrémité libre (6b), pour s'accoupler à la poignée de commande du moyen (M2) réalisée sous la forme d'une bande de préhension (13). La sangle (6) ainsi agencée constitue dans sa globalité le moyen de commande (M2) pour la mise en position relative de la structure de dos de sac et du harnais.Furthermore, according to the invention, the control means (M2) includes a strap (6) whose one end (6a) is secured to the connecting belt (5) in a zone (10) located at the place fastening said belt (5) with the harness (2). Said strap (6), as shown in Figures 9 to 13, bypasses the locking mechanism (11) and bears thereon in particular on the extension portion (11b) of the rocking lever (11). The strap (6) wraps around the upper axis (7g) and is then guided between the back structure and the rear end of the connecting belt (5). The strap (6) has on its free end strand (6b) to mate with the control handle of the means (M2) in the form of a gripping strip (13). The strap (6) thus arranged constitutes in its entirety the control means (M2) for the relative positioning of the bag back structure and the harness.

Dans cette mise en oeuvre, le moyen de renvoi supérieur (7) présente un axe (7g) qui permet le passage et le renvoi de la sangle (6), avec une orientation de ladite sangle (6) en situation oblique hors du plan de la courroie sans fin de liaison (5) et pour être tirée par le porteur. L'axe (7g) est conformé dans une configuration bombée ou conique (7g1). Cette configuration bombée ou conique est fonction de la largeur de la sangle (6) et du choix de l'orientation donnée au positionnement de celle-ci. Cela a pour effet de permettre une orientation de la sangle (6) latéralement par glissement et l'amener à prendre la position en oblique.In this implementation, the upper return means (7) has an axis (7g) which allows the passage and return of the strap (6), with an orientation of said strap (6) obliquely out of the plane of the endless binding belt (5) and to be pulled by the wearer. The axis (7g) is shaped in a convex or conical configuration (7g1). This convex or conical configuration is a function of the width of the strap (6) and the choice of the orientation given to the positioning of the latter. This has the effect of allowing an orientation of the strap (6) laterally by sliding and cause it to take the position obliquely.

Dans le cas où la sangle peut être tirée dans une orientation à droite ou à gauche du dos du sac, ledit axe (7g) présente une configuration bombée et la sangle (6) est de largeur inférieure environ de moitié à la longueur de l'axe (7g) pour être positionnée et glissée alternativement à droite et à gauche donnant l'orientation voulue.In the case where the strap can be pulled in an orientation to the right or left of the back of the bag, said axis (7g) has a curved configuration and the strap (6) is of width less than half the length of the axis (7g) to be positioned and slid alternately right and left giving the desired orientation.

Si l'orientation de la sangle (6) en oblique n'est que d'un côté, l'axe (7g) est conique avec une pente orientée dans le sens du côté de positionnement de la sangle. La largeur de la sangle peut être alors plus importante.If the orientation of the strap (6) obliquely is only one side, the axis (7g) is conical with a slope oriented in the direction of the positioning side of the strap. The width of the strap can be then greater.

Il convient de se référer aux figures pour exposer les modalités d'usage du dispositif de l'invention.Reference should be made to the figures to describe the methods of use of the device of the invention.

L'actionnement du moyen de commande (M1) entraîne la sollicitation du moyen (4) et donc la traction de la courroie de liaison (5) associée au harnais (2) sur lequel est attachée l'extrémité (4c) du moyen (4). Cela provoque le défilement vers le bas de la courroie (5) et ce, à l'encontre du moyen de verrouillage (11) qui pivote selon la flèche (F1), le dos de sac remonte selon la flèche (F2), le harnais restant en place sur l'utilisateur.Actuation of the control means (M1) causes the biasing of the means (4) and therefore the traction of the connecting belt (5) associated with the harness (2) to which the end (4c) of the means (4) is attached. ). This causes the belt (5) to move downwards and against the locking means (11) which pivots according to the arrow (F1), the back of the bag rises according to the arrow (F2), the harness remaining in place on the user.

Lorsque c'est le moyen de commande (M2) qui est entraîné, cela entraîne l'actionnement de la sangle (6). Par l'effort de traction, la sangle fait pivoter le levier (11) par un appui sur sa branche en prolongement (11b) libérant ainsi la courroie de liaison (5). Cela permet le déplacement vers le bas du dos de sac.When the control means (M2) is driven, this causes the operation of the strap (6). By the tensile force, the strap rotates the lever (11) by pressing on its branch extension (11b) thereby releasing the connecting belt (5). This allows the downward movement of the back of the bag.

Selon une autre caractéristique de l'invention, celle-ci inclut un moyen de contrôle et de lecture en position permettant au porteur de mémoriser les positions relatives de la structure de dos- harnais les plus appropriées selon les conditions d'utilisation.According to another characteristic of the invention, this includes a means of control and reading in position allowing the wearer to memorize the relative positions of the structure of back-harnesses most appropriate according to the conditions of use.

Selon une disposition particulière, la sangle (6) présente sur une partie de sa longueur, sensiblement à l'endroit de passage et de contournement du moyen de renvoi (7) une échelle graduée (14) selon un pas préétabli et définissant ainsi des positions relatives de la structure de dos par rapport au harnais.According to one particular arrangement, the webbing (6) has, over a part of its length, substantially at the point of passage and bypass of the deflection means (7), a graduated scale (14) in a pre-established pitch and thus defining positions relative structure of the back with respect to the harness.

Cette échelle graduée (14) est visible par le porteur et un index de repérage (15) peut être établi sur le moyen de renvoi (7) précité permettant d'établir la base de référence.This graduated scale (14) is visible to the wearer and a registration index (15) can be established on the aforementioned means of return (7) for establishing the reference base.

Dans une mise en oeuvre particulière cependant (figures 11 à 13), le moyen de renvoi (7) supérieur est agencé pour recevoir un capot de protection (16) de l'ensemble du mécanisme de verrouillage (11). Ce capot de protection (16) est monté fixe ou articulé sur le moyen de renvoi, et il est réalisé en tout matériau approprié. II présente sur sa face avant (16a) une fenêtre (16b) verticale qui est susceptible d'être en regard de la sangle (6) et de son échelle graduée en particulier. Le capot présente alors l'index de référence (15). Le porteur peut donc parfaitement visualiser la zone graduée de la sangle (6), et mémoriser les graduations appropriées correspondant à des positions spécifiques de la structure de dos par rapport au harnais. Cet aménagement est pratique, le réglage étant rapide, d'autant s'il y a plusieurs porteurs différents de la structure de dos, ou s'il y a, par suite de manipulation inappropriée, des modifications de réglage. L'échelle graduée peut être numérique, alphanumérique ou autre.In a particular embodiment however (FIGS. 11 to 13), the upper return means (7) is arranged to receive a cover of protection (16) of the entire locking mechanism (11). This protective cover (16) is fixedly mounted or articulated on the return means, and is made of any suitable material. It has on its front face (16a) a vertical window (16b) which is likely to be opposite the strap (6) and its graduated scale in particular. The cover then has the reference index (15). The wearer can thus perfectly visualize the graduated zone of the strap (6), and memorize the appropriate graduations corresponding to specific positions of the back structure relative to the harness. This arrangement is practical, the setting being fast, especially if there are several different carriers of the back structure, or if there is, due to improper handling, adjustment changes. The graduated scale can be numeric, alphanumeric or other.

Ainsi, selon l'invention, le porteur peut ajuster et optimiser, de manière micro-métrique, le positionnement de la structure de dos associé au Produit par rapport au harnais de portage.Thus, according to the invention, the wearer can adjust and optimize, in a micro-metric manner, the positioning of the back structure associated with the product relative to the carrying harness.

La mise en place est aisée à réaliser et simple dans sa mise en oeuvre. La solution apportée permet d'offrir un meilleur confort au porteur qui peut ajuster en toutes circonstances et immédiatement en position le Produit. Le contrôle de la position de la structure de dos par rapport au harnais présente aussi un confort d'utilisation.The implementation is easy to perform and simple in its implementation. The solution provided allows to offer a better comfort to the wearer who can adjust in all circumstances and immediately in position the Product. The control of the position of the back structure relative to the harness also has a comfort of use.

L'invention s'applique au Produit précité dont les applications qui ont été illustrées sont données à titre non limitatif.The invention applies to the aforementioned Product whose applications which have been illustrated are given without limitation.
