Description

Bagage convertible, notamment de type sac à dos  Convertible luggage, including bag-type
Domaine technique Technical area
L'invention concerne les bagages convertibles qui par simple appareillage peuvent tenir une autre fonction ou d'autres fonctions, pouvant notamment servir de siège. Il s'agit de bagages équipés d'une ossature rigide pliante en profilés métalliques et revêtement, ainsi que d'accessoires supplémentaires notamment en matière flexible, qui donnent au sac d'abord un aspect de sac à dos ou éventuellement de sac de courses ou de valise trolley. The invention relates to convertible luggage which by simple apparatus can hold another function or other functions, which can be used as a seat. This is luggage equipped with a rigid frame folding metal profiles and coating, as well as additional accessories including flexible material, which give the bag first appearance of a backpack or possibly shopping bag or trolley case.
Les techniques existantes Existing techniques
Actuellement, il existe de nombreux modèles de sacs à dos, de sac de courses ou bien de valises, éventuellement à roulettes, et également de nombreux modèles de sièges pliants, où l'ossature est constituée en profilés métalliques et le dessus en matières textile. De tels sièges existent de différents types, allant du simple trépieds, avec les trois pieds qui se croisent à mi-hauteur, où ils sont articulés entre eux, et où aux extrémités supérieures se trouve une pièce de matière textile triangulaire, qui après déploiement dudit trépied, crée une surface d'assise ; en passant par des sièges à quatre pieds de construction similaire, où deux arcs sont reliés en croix, sur le côté supérieur desquels est toujours enfilée la surface d'assise en matière textile ou même par exemple en cuir ; jusqu'aux fauteuils ou transats plus complexes et plus confortables, avec dossier et accoudoirs voire même avec pare- soleil, ou l'ossature est alors encore plus segmentée mais les dimensions et le poids sont alors plus élevés. On connaît aussi des bagages avec un certain degré de variabilité, d'une part pourvus de roues pour leur permettre de rouler, d'autre part parfois sur la surface supérieure des bagages souvent rigides, une surface est prévue pouvant être utilisée comme siège. Les derniers bagages populaires cités ont une construction et des dimensions de valises courantes et leur inconvénient réside ici en l'impossibilité de plier le bagage lorsqu'il est transporté sans contenu, ou quand on ne prévoit pas son utilisation imminente comme siège. Dans le cadre des types connus de sièges convertibles, il y a par exemple le célèbre siège selon le brevet US D306, 543, où le populaire siège pliant avec dossier pouvant être rangé dans un sac plat de type serviette avec poignées adaptées au transport du siège en position pliée, où la surface d'assise et du dossier servent de contenant avec fermeture à glissière pour contenir l'ossature après son basculement en position plate. Ce siège ne présente toutefois, ni déployé, ni sous sa forme pliée, aucun espace de rangement, hormis l'espace de rangement pour la construction elle-même. On connaît aussi le siège pliant selon le brevet US 6,264,078, où l'ossature elle-même du siège a une structure quelque peu différente de celle du siège selon le brevet US D306.543, mais le principe d'enveloppe sur la base du siège et du dossier plié est ici presque identique au brevet précité. Ici non plus, il n'apparait aucun espace de rangement supplémentaire. On devine un bagage avec espace de rangement et usage pour s'asseoir par exemple dans le brevet US 5,819,999, où il s'agit d'un sac à dos avec, attaché à sa partie dorsale, un plateau à pli transversal au milieu, où le plateau se détache du sac à dos et se déploie comme un siège sans pied, possédant uniquement des extrémités recourbées et des deux côtés un couplage de l'extrémité avant du siège à l'extrémité supérieure du dossier. Ici, l'assise est prévue sur une base surélevée, où seul est amélioré le confort de l'assise par un moelleux cousin de siège et la création d'un dossier. C'est dans un principe similaire jusqu'à une certaine mesure qu'a été conçu le bagage selon le brevet US 2009/0308706. Il s'agit d'un chariot à quatre roues de type valise trolley, plus précisément de chariot ou diable pliant, où le siège est créé comme une construction pliante, en position de transport intégrée dans la partie verticale de l'ossature du chariot. Pas même ici, le bagage lui- même n'est pliant, sachant que le bagage est ici le ou les conteneurs, les valises ou cartons, déposés sur la plate-forme de chargement du chariot. On connaît même un bagage à caractère de sac à dos, selon le brevet US 5,927,798, où sur la paroi dorsale dudit sac à dos est accrochée l'ossature pliante d'un siège, créé sur le principe de croisement des montants, où entre les cloisons supérieures se tend une surface d'assise en position déployée. Outre le seul accrochage du siège à la partie dorsale du sac à dos, il n'y a apparemment aucune autre intégration du siège au sac décrit. Currently, there are many models of backpacks, shopping bag or suitcase, possibly with wheels, and also many models of folding seats, where the frame is made of metal profiles and the top of textile. Such seats exist of different types, ranging from simple tripods, with the three feet that intersect at half height, where they are articulated together, and where at the upper ends is a piece of triangular textile material, which after deployment of said tripod, creates a seating surface; through four-legged seats of similar construction, where two arches are connected in a cross, on the upper side of which is always threaded the seat surface of textile material or even for example leather; to the more complex and comfortable chairs or loungers, with backrest and armrests or even with sun visor, or the frame is then even more segmented but the dimensions and weight are then higher. Also known luggage with a certain degree of variability, on the one hand provided with wheels to allow them to roll, sometimes on the upper surface of the often rigid luggage, a surface is provided that can be used as a seat. The last popular baggage items mentioned have a standard construction and dimensions of suitcases and their disadvantage lies here in the impossibility of folding the baggage when it is transported without contents, or when it is not foreseen its imminent use as a seat. In the context of the known types of convertible seats, there is for example the famous seat according to the US patent D306, 543, where the popular folding seat with backrest can be stored in a flat towel-type bag with handles to transport the seat in a folded position, where the seat and backrest surface serve as a zippered container for holding the frame after tilting to a flat position. This seat, however, does not have, nor deployed in its folded form, any storage space, except the storage space for the construction itself. The folding seat according to US Pat. No. 6,264,078 is also known, where the frame itself of the seat has a structure somewhat different from that of the seat according to US Pat. No. D306,543, but the principle of envelope on the base of the seat. and the folded file is here almost identical to the aforementioned patent. Here again, there is no additional storage space. One guesses a luggage with storage space and use to sit for example in US Patent 5,819,999, where it is a backpack with attached to its dorsal part, a transverse fold tray in the middle, where the tray detaches from the backpack and unfolds like a seat without a foot, having only bent ends and on both sides a coupling from the front end of the seat to the upper end of the backrest. Here, the seat is provided on a raised base, where only the comfort of the seat is improved by a soft seat cousin and the creation of a folder. It is in a similar principle to a certain extent that was designed luggage according to US Patent 2009/0308706. It is a trolley-type trolley with four wheels, more specifically a trolley or folding trolley, where the seat is created as a folding construction, in the integrated transport position in the vertical part of the frame of the trolley. Not even here, the luggage itself is folding, knowing that the luggage is here or the containers, the suitcases or cartons, deposited on the loading platform of the trolley. There is even known baggage character of backpack, according to US Patent 5,927,798, where on the back wall of said backpack is hung the folding frame of a seat, created on the principle of cross amounts, where between upper partitions is stretched a seating surface in the deployed position. In addition to the only attachment of the seat to the back portion of the backpack, there is apparently no further integration of the seat to the bag described.
Pour toutes les constructions connues décrites avec création d'un siège pliant, voire même combinaison de siège pliant avec bagage, le pliage du bagage même n'est pas réglé, étant toutefois généralement possible, mais nullement en combinaison avec le pliage du siège. On connaît même la solution apportée par le brevet CZ U 23492, où l'objectif est de créer un siège convertible tel, qu'outre son couplage avec un bagage, il soit possible de plier et de déployer simultanément les deux membres de ce système, et où il soit en même temps possible d'utiliser le siège même si le bagage n'a pas à être plié ou déployé. De plus, la construction selon le brevet cité règle le problème esthétique, où il est souhaitable dans de nombreux cas que l'ossature de telles constructions soit plutôt cachée, du moins quand le siège est utilisé comme bagage, car souvent l'utilisateur ne souhaite pas qu'il soit évident que, par exemple, en plus de son sac de courses il transporte aussi un siège, ce qui accuse sa condition physique moindre et / ou son âge avancé. For all the known constructions described with creation of a folding seat, or even combination of folding seat with luggage, the folding of the baggage itself is not adjusted, however being generally possible, but not in combination with the folding of the seat. We even know the solution brought by the patent CZ U 23492, where the objective is to create a convertible seat such that, in addition to its coupling with a luggage, it is possible to fold and deploy simultaneously the two members of this system, and where it is possible at the same time to use the seat even if the luggage does not have to be folded or deployed. In addition, the construction according to the patent cited rules the aesthetic problem, where it is desirable in many cases that the frame of such constructions is rather hidden, at least when the seat is used as luggage, because often the user does not wish not that it is obvious that, for example, in addition to his shopping bag he also carries a seat, which accuses his lower physical condition and / or his advanced age.
Si le bagage convertible doit être réalisé concrètement comme un sac à dos, alors les variantes décrites de façon assez générales, apparentes dans le brevet cité CZ U 23492, ont aussi une version avec bretelles de portage, qui présente un bagage ressemblant à un sac à dos, où toutefois, pour l'utilisation pratique optimale de cette construction, concrètement pour le bagage à l'aspect de sac à dos classique, il faut résoudre aussi une combinaison d'autres détails de construction, notamment l'agencement de l'espace de rangement par rapport à l'installation, la fixation et le camouflage de l'ossature porteuse de la partie siège de l'ensemble du bagage. L'objectif de la solution technique ci-jointe apparaît justement comme la création d'une combinaison optimale d'éléments de la gaine, de l'ossature et des compartiments de l'espace de rangement dans un te! sac de type sac à dos.  If the convertible luggage must be made concretely as a backpack, then the variants described in a rather general manner, apparent in the patent cited CZ U 23492, also have a version with carrying straps, which has a luggage resembling a bag to back, where however, for the optimal practical use of this construction, concretely for luggage in the appearance of classic backpack, it is also necessary to solve a combination of other details of construction, including the arrangement of space storage relative to the installation, fixing and camouflage of the supporting frame of the seat part of the entire baggage. The purpose of the technical solution is to create an optimal combination of elements of the duct, the frame and the compartments of the storage space in one! bag-type backpack.
Le principe de l'invention The principle of invention
L'optimisation annoncée dans le choix et la configuration des différents éléments du bagage convertible est principalement réglée et le bagage convertible de type sac à dos qui est aussi bien pliant que transformable ou utilisable comme siège, est conçu selon la présente invention, et ce par un bagage convertible notamment de type sac à dos, impliquant une ossature croisée pliante avec surface d'assise flexible et gaine flexible, délimitant l'espace de rangement dans ce bagage, où dans le même temps, l'ossature croisée pliante est placée le long du pourtour de l'espace de rangement du bagage, est durablement logée dans la gaine du bagage et appareillée pour le pliage et le déploiement dans le sens perpendiculaire par rapport à la paroi dorsale du bagage et en même temps la surface d'assise flexible est sous forme de revêtement flexible, attaché à la partie supérieure de l'ossature croisée pliante, tandis que le principe réside dans le fait que l'espace de rangement comprend au moins deux compartiments principaux où le premier compartiment principal est délimité par la paroi primaire ou dorsale à armature, délimité ensuite par des parois latérales moins rigides que la paroi primaire ou dorsale à armature, délimité enfin par une cloison souple d'une épaisseur et d'une rigidité encore inférieure à l'épaisseur et la rigidité des parois latérales, tandis que dans ce premier compartiment principal est logée l'ossature croisée pliante, sachant que les parois latérales sont dans leur moitié inférieure conçues dans une largeur telle, qu'elle recouvre l'ossature croisée pliante aussi bien en position pliée, qu'en position déployée, alors que lesdites parois latérales sont dans leur moitié supérieure conçues dans une largeur telle, qu'elle recouvre l'ossature croisée pliante uniquement en position repliée, tandis que lesdites parois latérales sont dans cette moitié supérieure y compris dans la partie horizontale supérieure de ladite paroi latérale dans le sens du pourtour du bagage, interrompues et connectées par le raccordement supérieur à ouverture, sous lequel est fixé, dans l'étendue entre la paroi dorsale à armature et la paroi avant externe du bagage, le rabat supérieur flexible d'une largeur qui recouvre l'ossature croisée pliante dans sa moitié supérieure aussi bien en position plié que déployée et sachant que la partie inférieure horizontale de la paroi latérale est pourvue de points d'attache reliés aux extrémités inférieures libres de l'ossature croisée pliante et reliés entre eux de sorte que, cette interconnexion des points d'attache des extrémités inférieures libres qui s'éloignent les unes des autres lors du déploiement de l'ossature croisée pliante, détermine le plus grand écartement possible entre chaque couple desdites extrémités inférieures libres qui s'éloignent les unes des autres et en même temps le deuxième compartiment principal est délimité par la paroi avant externe, les parois latérales et enfin délimité par une cloison souple dont l'épaisseur et la rigidité sont inférieures à l'épaisseur et la rigidité des parois latérales et de la paroi avant externe. Il est avantageux de fixer le rabat flexible supérieur sur les côtés également aux parois latérales, dans l'étendue entre la paroi avant externe et la paroi primaire ou dorsale à armature. Il est aussi avantageux si le raccordement supérieur à ouverture reliant l'ouverture du pourtour dans la partie supérieure des parois latérales, y compris la partie horizontale supérieure desdites parois latérales, est réalisé comme une fermeture à glissière. Il est ensuite avantageux si la cloison flexible entre le premier compartiment principal et le deuxième compartiment principal de l'espace de rangement est reliée à la gaine flexible du bagage le long de son pourtour, et ce à la jonction des parois latérales avec la paroi avant externe du bagage et en même temps ses dimensions et sa forme répondent aux dimensions et à la forme du premier compartiment principal de l'espace de rangement du bagage dans l'étendue entre le niveau ou la surface de la jonction de la cloison flexible à la gaine flexible du bagage et le niveau ou la surface de la paroi dorsale à armature. L'ossature croisée pliante est conçue en soi avantageusement, de sorte que sur les côtés, se trouvent entrecroisés et au niveau du croisement reliés entre eux par un pivot les pieds qui sont reliés dans la partie supérieure et inférieure de l'ossature croisée pliante, d'un côté à l'autre par des barres horizontales, auxquelles est attaché dans la partie supérieure, un revêtement flexible, créant en même temps la couche porteuse de la surface d'assise flexible et où le revêtement flexible relie entre elles ces barres horizontales supérieures, en position déployée du bagage, et ce en limitant par la longueur de ce revêtement flexible l'ouverture libre de la partie supérieure de l'ossature croisée pliante. Il est ensuite avantageux, pour la construction décrite de l'ossature croisée pliante, si les pieds de l'ossature croisée pliante passent par les ouvertures, créées dans la partie inférieure horizontale de la paroi latérale de la gaine flexible du bagage, où en même temps cette partie inférieure horizontale de la paroi latérale, dans les zones entre ces ouvertures pour les pieds de l'ossature croisée pliante, forme des points d'attache, reliés aux extrémités inférieures libres de l'ossature croisée pliante, alors qu'en même temps les barres horizontales inférieures entre les pieds de l'ossature croisée pliante dans sa partie inférieure sont un élément limitant l'avancement de ces pieds depuis le premier compartiment principal de l'espace de rangement vers le bas. En liaison avec les pieds de l'ossature croisée pliante il est ensuite avantageux si leur partie, dépassant vers le bas depuis l'espace de rangement est recouverte par le rabat flexible inférieur. Ce rabat inférieur flexible est avantageusement attachée à la gaine flexible du sac, sur l'un de ses côtés longitudinaux à l'aide d'une glissière inférieure séparable, par ouverture ou par retrait, et de son autre côté longitudinal, au moins en un emplacement à l'aide d'une bande autoagrippante (velcro), et où au moins dans le tiers central de la longueur du deuxième côté longitudinal du rabat inférieur flexible est logée une partie de l'élément magnétique de jonction, dont la deuxième partie est placée à la surface de la paroi avant externe du bagage, tandis qu'en même temps sur la partie inférieure horizontale de la paroi latérale du bagage apparaît parallèlement au rabat inférieur une poche de rangement dudit rabat inférieur flexible, pouvant être fermé à l'aide de la glissière inférieure de la poche. Il est également avantageux, si l'ossature croisée pliante est dans sa partie inférieure équipée d'au minimum deux roues. Il est enfin avantageux si le bagage est équipé dans la partie supérieure de sa paroi avant externe et de sa paroi primaire ou dorsale à armature, de poignées flexibles, où la paroi dorsale ou primaire à armature est en même temps conçue comme la paroi dorsale du sac à dos, laquelle est équipée de bretelles de portage. Ces poignées peuvent servirent d'une part pour maintenir le sac au moment de l'assise d'une personne sur le bagage, pour éviter qu'il ne tombe ou qu'il ne glisse sur le côté, notamment s'il est équipé de roulettes, d'autre part elles peuvent servir à se saisir des côtés respectifs du bagage pour faciliter son déploiement, donc pour le dépliage à partir de la position pliée, ou bien on peut aussi accrocher le bagage auxdites poignées, ou par exemple en cas de charge relativement lourde, le porter plus facilement à deux. Les bretelles de portage sont opportunes notamment dans la version réalisée typiquement comme un sac à dos, elles peuvent être opportunes aussi dans la version bagage ou éventuellement même valise, où ce n'est plus aussi typique, mais même une telle variante est possible. Pourtant, aussi bien la version sac que valise peuvent être pourvues de roues, mais pas nécessairement. The optimization announced in the choice and configuration of the different elements of the convertible baggage is mainly regulated and the convertible luggage type backpack that is both folding and convertible or usable as a seat, is designed according to the present invention, and by a convertible bag including a backpack, involving a folding cross frame with flexible seat surface and flexible sheath, defining the storage space in this luggage, where at the same time, the folding cross frame is placed along the periphery of the luggage storage space, is permanently housed in the luggage sheath and fitted for folding and deployment in the direction perpendicular to the back wall of the luggage and at the same time the flexible seat surface is in the form of a flexible covering, attached to the upper part of the folding cross frame, while the principle is that the storage space comprises at least two main compartments where the first main compartment is delimited by the primary wall or dorsal armature, then delimited by side walls less rigid than the primary wall or dorsal frame, finally delimited by a flexible partition of a thickness and rigidity still less than the thickness and rigidity of the side walls, while in this first main compartment is housed the folding cross frame, knowing that the side walls are in their lower half designed in such a width, that it covers the folding cross frame both in folded position, in position deployed, while said side walls are in their upper half designed in such a width, that it covers the oss folded cross only in the folded position, while said side walls are in this upper half including in the upper horizontal part of said side wall in the direction of the perimeter of the luggage, interrupted and connected by the upper opening connection, under which is secured, in the extent between the backed frame wall and the outer front wall of the luggage, the flexible upper flap of a width which covers the folding cross frame in its upper half both in the folded and deployed position and knowing that the horizontal lower part of the side wall is provided with attachment points connected to the free lower ends of the folding cross frame and connected together so that this interconnection of the attachment points of the free lower ends which move away from each other; others during the deployment of the folding cross frame, determines the widest spacing possible between each pair of said free lower ends which move away from each other and at the same time the second main compartment is delimited by the outer front wall, the side walls and finally delimited by a flexible partition whose thickness and rigidity are less than the thickness and rigidity of the side walls and the outer front wall. It is advantageous to attach the upper flexible flap on the sides also to the side walls, in the extent between the outer front wall and the primary or armored rear wall. It is also advantageous if the opening top connection connecting the circumferential opening in the upper part of the side walls, including the upper horizontal part of said side walls, is made as a zipper. It is then advantageous if the flexible partition between the first main compartment and the second main compartment of the storage space is connected to the flexible sheath of the luggage along its periphery, and at the junction of the side walls with the outer front wall of the luggage and at the same time its dimensions and its shape conform to the size and shape of the first main compartment of the luggage storage space in the area between the level or the surface of the junction of the flexible partition and the flexible sheath of the luggage and the level or surface of the dorsal wall with armature. The folding cross frame is designed in itself advantageously, so that on the sides are intersecting and at the crossing connected by a pivot the feet which are connected in the upper and lower part of the folding cross frame, from one side to the other by horizontal bars, to which is attached in the upper part, a flexible coating, creating at the same time the carrier layer of the flexible seat surface and where the flexible covering interconnects these horizontal bars in the extended position of the baggage, and this by limiting the length of this flexible coating the free opening of the upper part of the folding cross frame. It is then advantageous for the described construction of the folding cross frame, if the legs of the folding cross frame pass through the openings created in the horizontal lower part of the side wall of the flexible sheath of the luggage, where at the same time time this horizontal lower part of the side wall, in the areas between these openings for the legs of the folding cross frame, forms attachment points, connected to the lower free ends of the folding cross frame, while at the same time In the meantime, the lower horizontal bars between the legs of the folding cross frame in its lower part are an element limiting the advancement of these feet from the first main compartment of the storage space downwards. In connection with the legs of the folding crossframe it is then advantageous if their part, protruding downward from the storage space is covered by the lower flexible flap. This flexible lower flap is advantageously attached to the flexible sheath of the bag, on one of its longitudinal sides with the aid of a separable lower slide, by opening or by withdrawal, and its other longitudinal side, at least one location by means of a Velcro-fastening strip, and wherein at least in the central third of the length of the second longitudinal side of the flexible lower flap is housed a part of the magnetic connecting element, the second part of which is placed on the surface of the outer front wall of the luggage, while at the same time on the lower horizontal side wall of the luggage appears parallel to the lower flap a storage compartment of said flexible lower flap, which can be closed using the lower slide pocket. It is also advantageous, if the folding cross frame is in its lower part equipped with at least two wheels. Finally, it is advantageous if the luggage is equipped in the upper part of its outer front wall and its primary or back-armored wall with flexible handles, where the rear or primary armored wall is at the same time designed as the back wall of the body. backpack, which is equipped with shoulder straps. These handles can serve on the one hand to maintain the bag when sitting on the luggage, to prevent it from falling or slipping on the side, especially if it is equipped with casters, on the other hand they can be used to seize the respective sides of the luggage to facilitate its deployment, so for unfolding from the folded position, or we can also hang the luggage to said handles, or for example in case of relatively heavy load, wear it more easily to two. The shoulder straps are appropriate especially in the version typically made as a backpack, they may be appropriate also in the baggage version or possibly even suitcase, where it is not so typical, but even such a variant is possible. However, both the bag and suit version can be wheeled, but not necessarily.
S'il est indiqué que la gaine flexible du sac délimite à l'intérieur l'espace de rangement, comprenant au minimum deux compartiments principaux, alors dans cet esprit on peut créer également une délimitation de l'espace de rangement partagé à l'intérieur en plusieurs compartiments principaux et éventuellement aussi en segmentant ces principaux compartiments par exemple par des cloisons en plusieurs sections ou espaces de rangement partiels. Il est également possible d'accrocher à la gaine du sac, de manière fixe ou détachable d'autres espaces de rangements comme des pochettes, des poches, etc.  If it is indicated that the flexible sheath of the bag delimits inside the storage space, comprising at least two main compartments, then in this spirit it is also possible to create a delimitation of the shared storage space inside. in several main compartments and possibly also by segmenting these main compartments for example by partitions in several sections or partial storage spaces. It is also possible to attach to the sheath of the bag, in a fixed or detachable manner, other storage spaces such as pouches, pockets, etc.
Ainsi est conçu ce bagage, notamment de type sac à dos, d'une grande polyvalence et avec la possibilité de créer deux modifications, celle du bagage et du siège, sachant que le bagage restera toujours utilisable comme sac à dos et aussi comme siège et il sera toujours possible de les plier en même temps, donc de plier en même temps les parties constituant le bagage et le siège, car le mécanisme de pliage est intégré directement au bagage lui-même. Explication des dessins Thus, this luggage is conceived, particularly of the backpack type, of great versatility and with the possibility of creating two modifications, that of the luggage and the seat, knowing that the luggage will always remain usable as a backpack and also as a seat and it will always be possible to fold them at the same time, so to fold at the same time the parts constituting the luggage and seat, because the folding mechanism is integrated directly to the luggage itself.

Exemple de réalisation de l'invention Exemplary embodiment of the invention
Le bagage convertible 00 de type sac à dos pris ici pour exemple est décrit comme un sac à dos contenant une ossature croisée pliante 10 avec une surface d'assise flexible 14 et une gaine flexible 20, délimitant l'espace de rangement dans ledit bagage 100, où en même temps l'ossature croisée pliante 10 est placée à l'intérieur et le long du pourtour de l'espace de rangement du sac 100, logée fixement dans la gaine flexible 20 du bagage 100 et réglée pour un pliage et un déploiement dans le sens perpendiculaire à la paroi dorsale à armature 21 du bagage 100, ici du sac à dos, et en même temps, la surface d'assise flexible 14 est fabriquée comme un revêtement flexible, attaché à la partie supérieure de l'ossature croisée pliante 10. La combinaison technique des éléments suivants, à l'aide desquels on parvient à des effets et possibilités avantageux et globaux d'utilisation du bagage décrit pour exemple, est essentielle. L'espace de rangement comprend deux compartiments principaux, sachant que le premier compartiment principal 210 et délimité par la paroi dorsale à armature 21, équipée de bretelles de portage 212. puis délimité par les parois latérales 24 dont la rigidité est inférieure à celle de la paroi dorsale à armature 21, et enfin délimité par la cloison flexible 23 dont l'épaisseur et la rigidité sont encore inférieures à l'épaisseur et la rigidité des parois latérales 24. C'est pourtant dans ce premier compartiment principal 210 que se trouve l'ossature croisée pliante 10 sachant que les parois latérales 24 sont dans leur moitié inférieure conçues d'une épaisseur telle, qu'elle recouvre l'ossature croisée pliante 10 aussi bien en position pliée qu'en position déployée, alors que les parois latérales 24 sont dans leur moitié supérieure, y compris la partie supérieure horizontale 242 de cette paroi latérale 24, d'une largeur telle, qu'elle recouvre l'ossature croisée pliante 10 uniquement dans sa position pliée, tandis que ces parois latérales 24 sont dans cette moitié supérieure, y compris la partie supérieure horizontale 242 de cette paroi latérale 24, dans le sens du pourtour du sac 100 interrompues et reliées par un raccordement supérieur à ouverture 240, ici une fermeture à glissière courante, sous laquelle dans l'étendue entre la paroi dorsale à armature 2J_ et la paroi avant externe22 du bagage 100, est attachée le rabat supérieure flexible 25 d'une largeur qui recouvre l'ossature croisée pliantelO dans sa moitié supérieure aussi bien en position pliée qu'en position déployée. La partie inférieure horizontale 241 de la paroi latérale 24 est pourvue de points d'attache 2410. reliés aux extrémités inférieures libres de l'ossature croisée pliante 10 et en même temps aux autres points d'attache 2410 reliés entre eux, de sorte que cette interconnexion des points d'attache 2410 lors du déploiement de l'ossature croisée pliante 10 et de l'éloignement des extrémités libres inférieures de la dite ossature 10^ détermine l'écartement maximal possible pour chaque couple desdites extrémités inférieures libres. En même temps, le deuxième compartiment principal 220 de l'espace de rangement est délimité par la paroi avant externe 22, les parois latérales 24, et enfin délimité par une cloison flexible 23 d'une épaisseur et d'une rigidité inférieures à l'épaisseur et la rigidité des parois latérales 24 et de la paroi avant externe 22. L'accès avec fermeture, au deuxième compartiment est conçu comme un raccordement avant à ouverture 222. qui est concrètement réalisé ici par une fermeture à glissière courante, laquelle après avoir été ouverte, ouvre ledit deuxième compartiment principal 220 pour placer ou retirer le contenu de ce deuxième compartiment principal 220. Le rabat flexible supérieur 25 est ici fixé en même temps sur les deux côtés aux parois latérales 24 dans l'étendue entre la paroi avant externe 22 et la paroi dorsale à armature 2Λ . La cloison flexible 23 entre le premier compartiment principal 210 et le deuxième compartiment principal 220 de l'espace de rangement est ici relié à la gaine flexible 20 du bagage 00 le long de son pourtour, et ce à la jonction des parois latérales 24 avec la paroi avant externe 22 du bagage 100 et en même temps ses dimensions et sa forme répondent aux dimensions et à la forme du premier compartiment principal 210 de l'espace de rangement du bagage 100 dans l'étendue entre le niveau ou la surface de jonction de la cloison flexible 23 avec la gaine flexible 20 du bagage et le niveau ou la surface de la paroi dorsale à armature 21 du sac à dos. Ainsi, c'est pratiquement tout l'espace de rangement, soit la somme du volume du premier compartiment principal 210 et du deuxième compartiment principal 220, qui est utilisable comme volume utile pour le matériel à y placer. L'ossature croisée pliante 10 est ici à elle-seule avantageuse, ainsi sur ses côtés sont conçus les pieds H entrecroisés entre eux et reliés à leur croisement par un pivot 110, lesquels dans la partie supérieure et inférieure de l'ossature croisée pliante 10 sont reliés des deux côtés par des barres horizontales supérieures 12 et des barres horizontales inférieures 13, où les cloisons supérieures horizontales 12 sont reliées à un revêtement flexible qui constitue en même temps la couche porteuse de la surface d'assise flexible 14 et où ce revêtement flexible relie entre elles ces barres horizontales supérieures 12, en position déployée du bagage 100, et cela en limitant l'ouverture libre de la partie supérieure de l'ossature croisée plianteThe convertible bag 00 of the backpack type taken here for example is described as a backpack containing a folding cross frame 10 with a flexible seating surface 14 and a flexible sheath 20 defining the storage space in said luggage 100 where at the same time the folding cross frame 10 is placed inside and along the periphery of the storage space of the bag 100, fixedly housed in the flexible sheath 20 of the luggage 100 and set for folding and deployment. in the direction perpendicular to the dorsal frame wall 21 of the baggage 100, here the backpack, and at the same time, the flexible seat surface 14 is manufactured as a flexible coating, attached to the upper part of the crossbeam Folding 10. The technical combination of the following elements, through which the advantageous and comprehensive effects and possibilities of use of the luggage described for example are achieved, is essential. The storage space comprises two main compartments, knowing that the first main compartment 210 and delimited by the rear wall frame 21, equipped with shoulder straps 212. then delimited by the side walls 24 whose rigidity is less than that of the rear wall 21, and finally delimited by the flexible partition 23 whose thickness and rigidity are still less than the thickness and rigidity of the side walls 24. However, it is in this first main compartment 210 that is the folding cross frame 10 knowing that the side walls 24 are in their lower half designed to a thickness such that it covers the folding cross frame 10 also in a folded position in the extended position, while the side walls 24 are in their upper half, including the upper horizontal portion 242 of this side wall 24, of such a width that it covers the folding cross frame 10 only in its folded position, while these side walls 24 are in this upper half, including the upper horizontal portion 242 of this side wall 24, in the direction of the periphery of the bag 100 interrupted and connected by an upper opening connection 240, here a current slide fastener, in which in the extent between the armored back wall 2J_ and the outer front wall 22 of the luggage 100, The flexible top flap 25 is attached with a width which covers the folding crossbeam in its upper half both in the folded and extended positions. The horizontal lower part 241 of the side wall 24 is provided with attachment points 2410. connected to the free lower ends of the folding cross frame 10 and at the same time to the other attachment points 2410 connected to each other, so that this interconnection of the attachment points 2410 during the deployment of the folding crossframe 10 and the removal of the lower free ends of said frame 10 ^ determines the maximum possible spacing for each pair of said free lower ends. At the same time, the second main compartment 220 of the storage space is delimited by the outer front wall 22, the side walls 24, and finally delimited by a flexible wall 23 of a thickness and a rigidity less than thickness and rigidity of the side walls 24 and the outer front wall 22. The access with closure, the second compartment is designed as an opening front connection 222. which is concretely realized here by a current zipper, which after having was opened, opens said second main compartment 220 to place or remove the contents of this second main compartment 220. The upper flexible flap 25 is here fixed at the same time on both sides to the side walls 24 in the extent between the outer front wall 22 and the back wall with 2Λ armature. The flexible partition 23 between the first main compartment 210 and the second main compartment 220 of the storage space is here connected to the flexible sheath 20 of the luggage 00 along its periphery, and at the junction of the side walls 24 with the outer front wall 22 of the luggage 100 and at the same time its dimensions and shape correspond to the dimensions and shape of the first main compartment 210 of the luggage storage space 100 in the extent between the level or the connecting surface of the flexible partition 23 with the sheath flexible bag 20 and the level or the surface of the rear wall frame 21 of the backpack. Thus, it is virtually all the storage space, ie the sum of the volume of the first main compartment 210 and the second main compartment 220, which can be used as a useful volume for the material to be placed there. The folding cross-frame 10 is here in itself advantageous, and on its sides are designed the feet H intersecting with each other and connected to their intersection by a pivot 110, which in the upper and lower part of the folding cross frame 10 are connected on both sides by upper horizontal bars 12 and lower horizontal bars 13, where the horizontal upper partitions 12 are connected to a flexible liner which is at the same time the carrier layer of the flexible seat surface 14 and where this coating flexible connects these upper horizontal bars 12, in the extended position of the luggage 100, and this by limiting the free opening of the upper part of the folding cross frame
10 par la longueur de cette surface d'assise flexible 14. Il y a ensuite pour la construction décrite ici, d'ossature croisée pliante 10 un aménagement où les pieds10 by the length of this flexible seat surface 14. There is then for the construction described here, folding cross frame 10 a layout where the feet
11 de l'ossature croisée pliante 10 traversent des points d'attache 2410, réalisés ici comme des ouvertures à bordures renforcées dans la partie horizontale inférieure 241 de la paroi latérale 24 de la gaine 20 du bagage, où en même temps cette partie horizontale inférieure 241 de la paroi latérale 24, dans les zones entre ces points d'attache 2410. des ouvertures déjà cités réalisées pour les pieds H, de l'ossature croisée pliante 1ÇL. crée des liaisons entre les points d'attache cités 2410. reliés aux extrémités libres inférieures de l'ossature croisée pliante 10, soit aux extrémités inférieurs libres des pieds H, tandis qu'en même temps celles des barres horizontales12,13 entre les pieds H de l'ossature croisée pliante 10, qui se trouve dans sa partie inférieure, soit les cloisons inférieures 13, sont un élément limitant de l'avancement desdits pieds H par les points d'attache 2410. ici donc par les ouvertures à bordures renforcées dans la partie horizontale inférieure 241 de la paroi latérale 24, et ce par l'élément limitant la mesure de l'avancement des pieds H depuis le premier compartiment 210 de l'espace de rangement vers le bas. En plus de cela, ladite liaison, réalisée par entrelacement des forces des points d'attache 24 0 par-dessus la surface qui les sépare, de la partie inférieure horizontale 241 de la paroi latérale 24, assure aussi la limite du déploiement libre de l'ossature croisée pliante 10, et cela dans sa partie inférieure, de même qu'une telle ouverture est limitée dans sa partie supérieure par la liaison mutuelle de leurs barres horizontales supérieures 12 à l'aide de la surface d'assise flexible 14. 11 of the folding crossbeam 10 pass through attachment points 2410, made here as openings with reinforced borders in the lower horizontal portion 241 of the side wall 24 of the sheath 20 of the luggage, where at the same time this lower horizontal portion 241 of the side wall 24, in the areas between these attachment points 2410. already mentioned openings made for the feet H, folding cross frame 1ÇL . creates bonds between the attachment points cited 2410. connected to the lower free ends of the folding cross-frame 10, either at the free lower ends of the legs H, while at the same time those of the horizontal bars 12, 13 between the legs H of the folding cross frame 10, which is in its lower part, the lower partitions 13, are a limiting element of the advancement of said feet H by the attachment points 2410. here, therefore, by the openings with reinforced edges in the lower horizontal portion 241 of the side wall 24, and this by the element limiting the measurement of the advancement of the feet H from the first compartment 210 of the storage space down. In addition to this, said connection, made by interleaving the forces of the attachment points 24 0 over the surface which separates them, from the horizontal lower part 241 of the side wall 24, also ensures the limit of the free deployment of the 10, and this in its lower part, as such an opening is limited in its upper part by the mutual connection of their upper horizontal bars 12 with the aid of the flexible seat surface 14.
Par rapport aux pieds 11 de l'ossature croisée pliante 10,. une adaptation a été réalisée ici, avec une partie des pieds 11 dépassant vers le bas de l'espace de rangement, recouverte par un rabat inférieur flexible 26. Ce rabat flexible inférieur 26 est ici attaché à la gaine flexible 20 du bagage 100 sur l'un de ses côtés longitudinaux à l'aide d'une glissière inférieure séparable 261, et cela par séparation ou par retrait, et de l'autre de ses côtés longitudinaux libres, ici uniquement en son milieu, à l'aide d'une bande autoagrippante (Velcro) 262, accrochable à la surface externe de la paroi dorsale à armature 21 du sac à dos et en même temps à mi- longueur de l'autre côté longitudinal libre du rabat flexible inférieur 26 se trouve logée la première partie 2641 de l'élément magnétique de jonction 264. ici concrètement un des deux aimants permanents, dont la deuxième partie 2642 ici donc le deuxième aimant permanent de pôle opposé, est placé à la surface de la paroi avant externe 22 du bagage 100, où il est possible alternativement de fixer le bord libre du rabat inférieur flexible 26. En même temps, sur la partie horizontale inférieure 241 de la paroi latérale 24 du bagage 100 apparaît, parallèlement à ce rabat flexible inférieur 26. une poche de rangement 260 de ce rabat inférieur flexible 26, pouvant être fermée par la fermeture à glissière de poche séparable inférieure 263. L'ossature croisée pliante 10 peut aussi avantageuse être équipée dans sa partie inférieure, d'un moins deux roues, sachant que cette réalisation n'est pas ici illustrée, par soucis de simplification. Comme avantage, le bagage 100 est ici équipé dans la partie supérieure de sa paroi avant externe 22 d'une poignée flexible avant 221 et dans la partie supérieure de sa paroi dorsale à armature 21 d'une poignée flexible arrière 211. où en même temps, la paroi primaire ou dorsale à armature (21) est dans cette version réalisée comme la paroi dorsale du sac à dos, pourvue des bretelles 212 déjà citées. Les poignées citées 221.211 peuvent servirent d'une part pour maintenir le bagage 100 au moment de l'assise d'une personne sur le bagage 100, pour éviter qu'il ne tombe ou qu'il ne glisse sur le côté, notamment s'il est équipé de roulettes, d'autre part elles peuvent servir à se saisir des côtés respectifs du bagage 100 pour faciliter son déploiement, donc pour le dépliage à partir de la position pliée, ou on peut aussi accrocher le bagage 100 à l'aide de ces poignées 221 ,211 , ou par exemple en cas de charge relativement lourde, le porter plus facilement à deux. Compared to the feet 11 of the folding cross frame 10 ,. an adaptation has been made here, with part of the feet 11 protruding down from the storage space, covered by a flexible lower flap 26. This lower flexible flap 26 is here attached to the flexible sheath 20 of the luggage 100 on the one of its longitudinal sides by means of a separable lower slide 261, and this by separation or by withdrawal, and on the other of its free longitudinal sides, here only in its middle, with the aid of a Velcro strap 262, hookable to the outer surface of the rear wall 21 of the backpack and at the same time halfway length of the other free longitudinal side of the lower flexible flap 26 is housed the first part 2641 of the magnetic junction element 264. here concretely one of the two permanent magnets, whose second part 2642 here therefore the second permanent magnet of opposite pole, is placed on the surface of the outer front wall 22 of the luggage 100, where i Alternatively, the free edge of the lower flexible flap 26 may be secured. At the same time, on the lower horizontal portion 241 of the side wall 24 of the luggage 100, parallel to the lower flexible flap 26, there is a storage pocket 260 of this bag. flexible lower flap 26, which can be closed by the lower separable pocket zipper 263. The folding crossframe 10 can also be advantageous in its lower part, of at least two wheels, knowing that this embodiment is not illustrated here, for the sake of simplification. As an advantage, the luggage 100 is here equipped in the upper part of its outer front wall 22 with a flexible front handle 221 and in the upper part of its rear frame wall 21 with a rear flexible handle 211. Where at the same time , in this version, the primary or dorsal frame wall (21) is made as the back wall of the backpack, provided with the straps 212 already mentioned. The handles mentioned 221.211 can serve on the one hand to hold the baggage 100 when a person sits on the luggage 100, to prevent it from falling or slipping on the side, particularly it is equipped with wheels, on the other hand they can be used to seize the respective sides of the luggage 100 to facilitate its deployment, so for unfolding from the folded position, or we can also hang the luggage 100 with the help of these handles 221, 211 or, for example, in the case of a relatively heavy load, more easily to two.
S'il est indiqué ici, que la gaine du bagage délimite à l'intérieur l'espace de rangement, comportant au minimum deux compartiments principaux, plus précisément dans la réalisation pilote présente, justement deux compartiments principaux 210,220, alors dans cet esprit, la délimitation de l'espace de rangement peut être réalisée par segmentation intérieure en plusieurs compartiments principaux et éventuellement par segmentation de ces compartiments principaux eux-mêmes 210,220, par exemple par des cloisons en plusieurs sections, ou segments partiels d'espaces de rangement. Il est également possible d'attacher à la gaine flexible 20 du bagage 100, durablement ou de façon détachable, d'autres espaces de rangement, comme des pochettes, poches, etc. L'ajout de ces autres compartiments, cloisons, etc. n'est pas ici représenté par soucis de simplification, mais leur réalisation est connue et un spécialiste dans ce domaine saura facilement les créer. Dans la version décrite, le sac à dos, peut même être complété, par les moyens habituels, d'une ceinture lombaire avec ouverture, etc.  If it is indicated here, that the sheath of the luggage delimits inside the storage space, comprising at least two main compartments, more precisely in the pilot embodiment present, precisely two main compartments 210,220, then in this spirit, the delimitation of the storage space can be achieved by internal segmentation into several main compartments and possibly by segmentation of these main compartments themselves 210,220, for example by partitions in several sections, or partial segments of storage spaces. It is also possible to attach to the flexible sheath 20 of the luggage 100, durably or releasably, other storage spaces, such as pouches, pockets, etc. The addition of these other compartments, partitions, etc. is not here represented for the sake of simplification, but their realization is known and a specialist in this field will easily create them. In the version described, the backpack, can even be completed, by the usual means, a lumbar belt with opening, etc.
Ici aussi, comme exemple, on réalise un bagage de type sac à dos avec une grande variabilité et la possibilité de réaliser les deux modifications, où le bagage sera toujours utilisable comme sac à dos et aussi comme siège et en même temps il sera toujours possible de le plier, en pliant en même temps les parties formant le bagage et le siège, car le mécanisme pliant est intégré directement à l'espace de rangement. Le premier compartiment principal 210 sert à recevoir l'ossature croisée pliante 0 et le sépare notamment du deuxième compartiment principal 220 qui est destiné à contenir le matériel, ainsi au contraire cette charge est protégée du contact avec cette ossature 10 et ainsi d'une détérioration éventuelle causée par l'ossature 10. Le rabat inférieur flexible 26 sert à protéger les objets et les personnes alentours de salissures et de détériorations causées par les extrémités libres des pieds H qui dépassent. Pourtant ce rabat flexible inférieur 26 peut, soit être entièrement enroulé et logé dans la poche 260, ou bien il peut être entièrement détaché. En position de recouvrement des pieds H le rabat flexible inférieur 26 attaché par sa lisière libre par une bande autoagrippante (Velcro) 262 à la partie inférieure de la paroi dorsale à armature 21, ou inversement en position de pieds 11 découverts, donc typiquement en position assise sur le siège, le rabat inférieur flexible 26 est attaché par sa lisière libre par un élément magnétique de raccordement 264 à la partie inférieure de la paroi avant externe 22. Here too, as an example, we realize a bag-type bag with great variability and the possibility of making both modifications, where the baggage will always be used as a backpack and also as a seat and at the same time it will always be possible fold it, at the same time folding the parts forming the luggage and the seat, because the folding mechanism is integrated directly into the storage space. The first main compartment 210 serves to receive the folding cross frame 0 and separates including the second main compartment 220 which is intended to contain the material, and on the contrary this load is protected from contact with the frame 10 and thus deterioration possibly caused by the frame 10. The flexible lower flap 26 serves to protect objects and people around dirt and damage caused by the free ends of feet H which protrude. However, this lower flexible flap 26 can either be fully wound and housed in the pocket 260, or it can be completely detached. In the covering position of the feet H the lower flexible flap 26 attached by its free edge by a hook and loop fastener (Velcro) 262 to the lower part of the backed frame wall 21, or conversely in the position of the feet 11 discovered, so typically when seated on the seat, the flexible lower flap 26 is attached by its free edge by a magnetic connecting element 264 to the lower part of the outer front wall 22.
