Description

Domaine techniqueTechnical area

L'invention se rapporte au domaine des bagages et, plus particulièrement à un bagage pliant.The invention relates to the field of luggage and, more particularly to a folding luggage.

Arrière-plan technologiqueTechnological background

Les bagages visent à permettre le transport d'objets divers et variés. Ainsi, des valises permettent par exemple de transporter des vêtements ou autres objets pouvant servir lors d'un déplacement.Luggage is intended to allow the transport of various and varied objects. Thus, suitcases make it possible, for example, to transport clothes or other objects that can be used when traveling.

Le document WO 2014/127497 A1 divulgue un bagage pliant comportant un premier et un deuxième panneaux rigides parallèles l'un à l'autre, un troisième et un quatrième panneaux rigides articulés chacun sur l'un des premier ou deuxième panneaux, et un cinquième et un sixième panneau qui relient chacun le premier et le deuxième panneaux.The document WO 2014/127497 A1 discloses a collapsible luggage having a first and a second rigid panels parallel to each other, a third and a fourth rigid panels each hinged on one of the first or second panels, and a fifth and a sixth panel which each connect the first and second panels.

Il est avantageux de maximiser le volume d'objets pouvant être transportés par un bagage unique. Lorsqu'ils sont inutilisés, les bagages doivent être entreposés afin de servir à des voyages futurs. Aussi, les bagages sont inutilement encombrants lorsqu'ils sont vides.It is advantageous to maximize the volume of objects that can be carried by a single piece of luggage. When unused, baggage should be stored for use on future trips. Also, luggage is unnecessarily bulky when empty.

Il est par conséquent avantageux de réduire l'encombrement des bagages lorsqu'ils sont vides. Pour ce faire, il est connu des bagages souples qui permettent de réduire très sensiblement leur encombrement lorsqu'ils sont vides. Toutefois, en contrepartie, ils sont généralement vulnérables aux dégradations et ne protègent pas bien leur contenu contre les chocs ou les vols.It is therefore advantageous to reduce the size of the luggage when it is empty. To do this, flexible luggage is known which makes it possible to very significantly reduce its bulk when empty. However, on the other hand, they are generally vulnerable to damage and do not protect their contents well against shocks or theft.

Résumésummary

Une idée à la base de l'invention est de proposer un bagage qui soit, d'une part, peu encombrant lorsqu'il est inutilisé, et d'autre part, suffisamment rigide lorsqu'il est utilisé pour protéger efficacement son contenu.One idea underlying the invention is to provide a piece of luggage which is, on the one hand, not bulky when it is not in use, and on the other hand, sufficiently rigid when it is used to effectively protect its contents.

L'invention est définie par les revendications en annexe.The invention is defined by the appended claims.

Pour ce faire, l'invention fournit un bagage pliant comportant :

  • un premier et un deuxième panneaux, rigides, qui sont parallèles l'un à l'autre;
  • un troisième et un quatrième panneaux, rigides, qui sont chacun montés articulés sur l'un des premier et deuxième panneaux entre une position déployée dans laquelle ledit troisième ou quatrième panneau s'étend entre lesdits premier et deuxième panneaux, perpendiculairement auxdits premier et deuxième panneaux, et une position escamotée dans laquelle ledit troisième ou quatrième panneau s'étend parallèlement auxdits premier et deuxième panneaux ; les troisième et quatrième panneaux définissant avec le premier et le deuxième panneaux un cadre rigide lorsque les troisième et quatrième panneaux sont dans leur position déployée ;
  • un cinquième et un sixième panneaux qui relient chacun le premier et le deuxième panneaux et qui définissent avec le premier, le deuxième, le troisième et le quatrième panneaux, lorsque lesdits troisième et le quatrième panneaux sont dans leur position déployée, un espace interne de rangement de forme parallélépipédique; le cinquième et le sixième panneaux étant déformables selon une direction x perpendiculaire auxdits premier et deuxième panneaux entre une position dépliée et une position pliée de telle sorte que, lorsque les troisième et quatrième panneaux sont dans leur position escamotée, le premier et le deuxième panneaux soient aptes à se déplacer l'un par rapport à l'autre selon la direction x entre une position écartée d'utilisation dans laquelle le cinquième et le sixième panneaux sont dans leur position dépliée, et une position rapprochée de rangement dans laquelle le cinquième et le sixième panneaux sont dans leur position pliée.
To do this, the invention provides a folding baggage comprising:
  • a first and a second rigid panel which are parallel to each other;
  • a third and a fourth panel, rigid, which are each mounted hinged on one of the first and second panels between an extended position in which said third or fourth panel extends between said first and second panels, perpendicular to said first and second panels , and a retracted position in which said third or fourth panel extends parallel to said first and second panels; the third and fourth panels defining with the first and the second panels a rigid frame when the third and fourth panels are in their position deployed;
  • a fifth and a sixth panels which each connect the first and the second panels and which together with the first, second, third and fourth panels define, when said third and fourth panels are in their deployed position, an internal storage space parallelepipedal in shape; the fifth and the sixth panels being deformable in an x direction perpendicular to said first and second panels between an unfolded position and a folded position such that, when the third and fourth panels are in their retracted position, the first and second panels are able to move with respect to each other in the x direction between a separated position of use in which the fifth and sixth panels are in their unfolded position, and a close storage position in which the fifth and the sixth sixth panels are in their folded position.

Ainsi, grâce à un tel agencement, les premier, deuxième, troisième et quatrième panneaux forment un cadre rigide conférant au bagage dans sa configuration dépliée d'utilisation, une rigidité lui permettant de protéger efficacement son contenu. En outre, l'encombrement du bagage est très faible lorsque les premier et deuxième panneaux sont dans leur position rapprochée de rangement.Thus, thanks to such an arrangement, the first, second, third and fourth panels form a rigid frame giving the baggage in its unfolded configuration of use, a rigidity allowing it to effectively protect its contents. In addition, the size of the baggage is very small when the first and second panels are in their close storage position.

Selon d'autres modes de réalisation avantageux, un tel bagage pliant peut présenter une ou plusieurs des caractéristiques suivantes.According to other advantageous embodiments, such a folding bag can have one or more of the following characteristics.

Selon un mode de réalisation, le cinquième panneau est réalisé dans un matériau souple et comporte :

Ceci permet d'assurer de manière simple un verrouillage du bagage pliant dans sa configuration pliée de rangement.According to one embodiment, the movable shutter is suitable for being positioned in a clamping position in which said movable shutter is wound around the first and second panels when said first and second panels are in their close position so as to keep them in said close position, the folding baggage comprising a second fixing device configured to hold the movable flap in its clamping position. This makes it possible to ensure in a simple manner a locking of the folding luggage in its folded storage configuration.

Selon un mode de réalisation, le volet mobile présente une forme rectangulaire et présente un bord qui est solidaire de l'encadrement et trois autres bords qui sont aptes à être fixés à l'encadrement dans la position de fermeture du volet mobile par le premier dispositif de fixation.According to one embodiment, the movable shutter has a rectangular shape and has an edge which is integral with the frame and three other edges which are able to be fixed to the frame in the closed position of the movable shutter by the first device. of fixation.

Description détaillée de modes de réalisationDetailed description of embodiments

Dans la description, un repère orthonormé tridimensionnel défini par trois axes x, y, z et représenté sur les figures 1 et 3 est utilisé pour décrire les éléments du bagage pliant.In the description, a three-dimensional orthonormal coordinate system defined by three axes x, y, z and represented on the figures 1 and 3 is used to describe the items of folding luggage.

En référence aux figures annexées, on décrit ci-après un bagage pliant selon un mode de réalisation. Dans ce mode de réalisation, le bagage pliant est une valise.With reference to the attached figures, a folding baggage item according to one embodiment is described below. In this embodiment, the folding baggage is a suitcase.

La valise 1 est représentée dans une configuration dépliée d'utilisation sur la figure 1 et dans une configuration pliée de rangement sur la figure 2. La valise 1 comporte six panneaux 2, 3, 4, 5, 6, 7 qui présentent chacun une forme générale rectangulaire et qui sont disposés perpendiculairement les uns par rapport aux autres de manière à définir un parallélépipède rectangle. Ainsi, les six panneaux 2, 3, 4, 5, 6, 7 définissent ensemble, lorsque la valise 1 est dans sa configuration dépliée d'utilisation, un espace interne de rangement qui présente une forme parallélépipédique rectangle et qui est apte à recevoir des objets.The case 1 is shown in an unfolded configuration of use on the figure 1 and in a folded storage configuration on the figure 2 . The case 1 comprises six panels 2, 3, 4, 5, 6, 7 which each have a generally rectangular shape and which are arranged perpendicular to each other so as to define a rectangular parallelepiped. Thus, the six panels 2, 3, 4, 5, 6, 7 together define, when the case 1 is in its unfolded configuration for use, an internal storage space which has a rectangular parallelepiped shape and which is suitable for receiving objects.

Plus particulièrement, la valise 1 comporte :

  • deux panneaux latéraux 2, 3 rigides qui sont parallèles l'un à l'autre ;
  • un panneau avant 5 et un panneau arrière 4, qui sont parallèles l'un à l'autre, relient les deux panneaux latéraux 2, 3 et forment les deux plus grandes faces du parallélépipède rectangle, lorsque la valise 1 est dans sa configuration dépliée d'utilisation ; et
  • un panneau inférieur 6 et un panneau supérieur 7, rigides, qui sont parallèles l'un à l'autre et forment les deux plus petites faces du parallélépipède rectangle, lorsque la valise 1 est dans sa configuration dépliée d'utilisation.
More particularly, the suitcase 1 comprises:
  • two rigid side panels 2, 3 which are parallel to each other;
  • a front panel 5 and a rear panel 4, which are parallel to each other, connect the two side panels 2, 3 and form the two largest faces of the rectangular parallelepiped, when the case 1 is in its unfolded configuration d 'use ; and
  • a lower panel 6 and an upper panel 7, rigid, which are parallel to one another and form the two smaller faces of the rectangular parallelepiped, when the case 1 is in its unfolded configuration for use.

Lorsque la valise 1 est dans sa position dépliée d'utilisation représentée sur la figure 1, les panneaux latéraux 2, 3 s'étendent chacun dans un plan parallèle aux axes z et y, les panneaux avant et arrière 5, 4 s'étendent chacun dans un plan parallèle aux axes x et z et les panneaux inférieur 6 et supérieur 7 s'étendent chacun dans un plan parallèle aux axes x et y.When the case 1 is in its unfolded position of use shown in the figure 1 , the side panels 2, 3 each extend in a plane parallel to the z and y axes, the front and rear panels 5, 4 each extend in a plane parallel to the x and z axes and the lower 6 and upper 7 panels each extend in a plane parallel to the x and y axes.

Le panneau inférieur 6 et le panneau supérieur 7 sont respectivement montés articulés sur l'un et l'autre des deux panneaux latéraux 2, 3. Plus particulièrement, comme représenté sur la figure 3, le panneau inférieur 6 est monté pivotant via un axe 26 sur le panneau latéral 3, au niveau de l'extrémité inférieure de la surface interne dudit panneau latéral 3. De même, le panneau supérieur 7 est monté pivotant, via un axe 26, sur le panneau latéral 2, au niveau de l'extrémité supérieure de la surface interne dudit panneau latéral 2. Les axes 26 de pivotement des panneaux inférieur 6 et supérieur 7 sont parallèles l'un à l'autre et orientés parallèlement à l'axe y. Ainsi, chacun des panneaux inférieur 6 et supérieur 7 est monté mobile sur l'un des panneaux latéraux 2, 3 entre une position déployée dans laquelle ledit panneau inférieur 6 ou supérieur 7 s'étend entre les deux panneaux latéraux 2, 3, perpendiculairement à ceux-ci, c'est-à-dire dans un plan parallèle aux axes x et y, et une position escamotée dans laquelle ledit panneau inférieur 6 ou supérieur 7 est rabattu contre le panneau latéral 2, 3 sur lequel il est articulé et s'étend ainsi sensiblement parallèlement aux panneaux latéraux 2, 3, c'est-à-dire dans un plan parallèle aux axes y et z.The lower panel 6 and the upper panel 7 are respectively mounted articulated on one and the other of the two side panels 2, 3. More particularly, as shown in FIG. figure 3 , the lower panel 6 is pivotally mounted via an axis 26 on the side panel 3, at the lower end of the internal surface of said side panel 3. Likewise, the upper panel 7 is pivotally mounted, via an axis 26, on the side panel 2, at the level of the upper end of the internal surface of said side panel 2. The pivot axes 26 of the lower 6 and upper 7 panels are parallel to each other and oriented parallel to the y axis. Thus, each of the lower 6 and upper 7 panels is movably mounted on one of the side panels 2, 3 between an extended position in which said lower 6 or upper panel 7 extends between the two side panels 2, 3, perpendicular to these, that is to say in a plane parallel to the x and y axes, and a retracted position in which said lower panel 6 or upper 7 is folded against the side panel 2, 3 on which it is articulated and s 'thus extends substantially parallel to the side panels 2, 3, that is to say in a plane parallel to the y and z axes.

Lorsqu'ils sont dans leur position déployée, les panneaux inférieur 6 et supérieur 7 définissent avec les panneaux latéraux 2, 3 un cadre rigide apte à assurer la rigidité de la valise 1. Lorsqu'ils sont dans leur position escamotée, les panneaux inférieur 6 et 7 autorisent un déplacement relatif des panneaux latéraux 2, 3 l'un par rapport à l'autre, selon la direction x, entre une position écartée d'utilisation, représentée sur la figure 1, et une position rapprochée de rangement, illustrée sur la figure 2.When they are in their deployed position, the lower 6 and upper 7 panels together with the side panels 2, 3 define a rigid frame capable of ensuring the rigidity of the case 1. When they are in their retracted position, the lower panels 6 and 7 allow a relative displacement of the side panels 2, 3 with respect to one another, in the x direction, between a position of use apart, shown in FIG. figure 1 , and a close storage position, illustrated on figure 2 .

Par ailleurs, les panneaux avant 5 et arrière 4 sont déformables selon la direction x entre une position dépliée, illustrée sur la figure 1 et une position pliée, illustrée sur la figure 2.Furthermore, the front 5 and rear 4 panels are deformable in the x direction between an unfolded position, illustrated in the figure. figure 1 and a folded position, shown on figure 2 .

Ainsi, pour passer de la configuration dépliée d'utilisation, illustrée sur la figure 1, à la configuration pliée de rangement, illustrée sur la figure 2, l'utilisateur déplace préalablement les panneaux inférieur 6 et supérieur 7 de leur position déployée vers leur position escamotée, dans laquelle ils sont rabattus contre les panneaux latéraux 2, 3. Dans un second temps, les panneaux latéraux 2, 3 sont rapprochés l'un de l'autre selon la direction x de leur position écartée vers leur position rapprochée. Les panneaux avant 5 et arrière 4 se déforment simultanément vers leur position pliée lors du rapprochement des panneaux latéraux 2, 3.Thus, to switch from the unfolded configuration of use, illustrated on figure 1 , in the folded storage configuration, shown on figure 2 , the user first moves the lower 6 and upper 7 panels from their deployed position to their retracted position, in which they are folded against the side panels 2, 3. Secondly, the side panels 2, 3 are brought together. one from the other in the x direction from their separated position to their close position. The front 5 and rear 4 panels deform simultaneously towards their folded position when the side panels 2, 3 are brought together.

A l'inverse, pour passer de la configuration pliée de rangement à la configuration dépliée d'utilisation, l'utilisateur écarte les panneaux latéraux 2, 3 l'un de l'autre vers leur position écartée. Les panneaux avant 5 et arrière 4 se déforment simultanément vers leur position dépliée lors de l'écartement des panneaux latéraux 2, 3. Puis, lorsque les panneaux latéraux 2, 3 sont dans leur position écartée, les panneaux inférieur 6 et supérieur 7 sont déplacés de leur position escamotée vers leur position déployée dans laquelle ils forment un cadre rigide avec les panneaux latéraux 2, 3.Conversely, to switch from the folded storage configuration to the unfolded configuration for use, the user moves the side panels 2, 3 away from each other towards their separated position. The front 5 and rear 4 panels deform simultaneously towards their unfolded position during the separation of the side panels 2, 3. Then, when the side panels 2, 3 are in their separated position, the lower 6 and upper 7 panels are moved. from their retracted position towards their deployed position in which they form a rigid frame with the side panels 2, 3.

En relation avec la figure 3, on décrit ci-dessous la structure particulière des différents composants de la valise 1.In relation to the figure 3 , the particular structure of the various components of the case 1 is described below.

Le panneau avant 5 est fixé au niveau de ses deux bords latéraux à l'un et à l'autre des deux panneaux latéraux 2, 3. Le panneau avant 5 est par exemple réalisé en tissu. Il est ainsi apte à se déformer pour autoriser le mouvement des panneaux latéraux 2, 3 entre leur position écartée et leur position rapprochée. Le panneau avant 5 présente une fente 39 en forme de U de manière à ménager un encadrement 40 définissant une ouverture rectangulaire permettant d'accéder à l'espace interne de rangement et un volet mobile 29, de forme rectangulaire, qui est apte à obturer l'ouverture dans une position de fermeture ou à laisser ladite ouverture accessible dans une position ouverte. Le panneau avant 5 présente également un dispositif de fixation qui est configuré pour maintenir le volet mobile 29 dans sa position de fermeture. Dans le mode de réalisation représenté, le dispositif de fixation comporte une fermeture à glissière 10 s'étendant le long de la fente 39 en forme de U et permettant de raccorder les trois bords libres du volet mobile 29 aux trois bords en regard de l'encadrement 40. La fermeture à glissière 10 est équipée d'une ou de plusieurs tirettes 11 permettant à l'utilisateur d'ouvrir le volet mobile 29 en vue d'accéder à l'espace interne de rangement ou de fermer le volet mobile 29. Dans un autre mode de réalisation non représenté, le dispositif de fixation comporte des surfaces autoaggripantes du type velours crochets. Ainsi, l'encadrement 40 est équipé d'une ou plusieurs surfaces autoaggripantes qui sont chacune aptes à coopérer avec une surface autoaggripante complémentaire portée par le volet mobile 29.The front panel 5 is fixed at its two side edges to one and the other of the two side panels 2, 3. The front panel 5 is for example made of fabric. It is thus able to deform to allow movement of the side panels 2, 3 between their separated position and their close position. The front panel 5 has a U-shaped slot 39 so as to provide a frame 40 defining a rectangular opening allowing access to the internal storage space and a movable shutter 29, of rectangular shape, which is able to close the opening in a closed position or leaving said opening accessible in an open position. The front panel 5 also has an attachment device which is configured to hold the movable shutter 29 in its closed position. In the embodiment shown, the fixing device comprises a zipper 10 extending along the U-shaped slot 39 and allowing the three free edges of the movable shutter 29 to be connected to the three opposite edges of the frame 40. The zipper 10 is equipped with one or more zippers 11 allowing the user to open the movable shutter 29 in order to access the internal storage space or to close the movable shutter 29. In another embodiment not shown, the fixing device comprises self-gripping surfaces of the hook velvet type. Thus, the frame 40 is equipped with one or more self-gripping surfaces which are each able to cooperate with a complementary self-gripping surface carried by the movable flap 29.

De manière avantageuse, le volet mobile 29 est apte à être positionné dans une position de serrage dans laquelle il est enroulé autour des panneaux latéraux 2, 3 de manière à les maintenir dans leur position rapprochée, tel que représenté sur la figure 7. Sur la figure 7, le volet mobile 29 est représenté de manière schématique à l'aide de traits pointillés et de hachures. Comme représenté par exemple sur la figure 1, la fente 39 en forme de U ménageant le volet mobile 29 est orientée de telle sorte que le bord du volet mobile 29 qui assure la liaison du volet mobile 29 à l'encadrement 40 s'étende le long de l'un des panneaux latéraux 2, 3 ; ce qui facilite l'enroulement dudit volet mobile 29 autour des panneaux latéraux 2, 3. En outre, la valise 1 est équipée d'un deuxième dispositif de fixation, non représenté, permettant de maintenir le volet mobile 29 dans sa position de serrage. Selon un mode de réalisation, le deuxième dispositif de fixation comporte des surfaces auto-aggripantes du type velours crochets. Ainsi, à titre d'exemple, le deuxième dispositif de fixation comporte une première surface auto-aggripante qui est arrangée sur la surface externe du volet mobile 29 et qui est apte à coopérer avec une deuxième surface auto-aggripante complémentaire qui est, par exemple, fixée sur le panneau latéral 2 ou sur le panneau avant 5. De manière alternative, selon les dimensions de la valise 1, la deuxième surface auto-aggripante peut également être fixée sur le volet mobile 29 lui-même de telle sorte que le volet mobile 29 est fixé sur lui-même en faisant un tour complet autour de la valise 1 dans sa configuration pliée de rangement. Selon d'autre mode de réalisation, le deuxième dispositif de fixation peut également être réalisé au moyen d'un ou de plusieurs boutons-pression.Advantageously, the movable shutter 29 is able to be positioned in a clamping position in which it is wound around the side panels 2, 3 so as to maintain them in their close position, as shown in FIG. figure 7 . On the figure 7 , the movable shutter 29 is shown schematically using dotted lines and hatching. As shown for example on figure 1 , the U-shaped slot 39 forming the movable flap 29 is oriented such that the edge of the movable flap 29 which connects the movable flap 29 to the frame 40 extends along one of the side panels 2, 3; which facilitates the winding of said movable shutter 29 around the side panels 2, 3. In addition, the case 1 is equipped with a second fixing device, not shown, making it possible to maintain the movable flap 29 in its clamping position. According to one embodiment, the second fastening device comprises self-gripping surfaces of the hook velor type. Thus, by way of example, the second fixing device comprises a first self-gripping surface which is arranged on the outer surface of the movable flap 29 and which is able to cooperate with a second complementary self-gripping surface which is, for example , fixed on the side panel 2 or on the front panel 5. Alternatively, depending on the dimensions of the case 1, the second self-gripping surface can also be fixed on the movable flap 29 itself so that the flap mobile 29 is fixed on itself by making a complete turn around the suitcase 1 in its folded storage configuration. According to another embodiment, the second fixing device can also be produced by means of one or more press studs.

Le panneau arrière 4 est réalisé dans un matériau plastique rigide, tel que du polyéthylène ou du polyvinyle. Afin de permettre sa déformation selon l'axe x lorsque les panneaux latéraux 2, 3 sont déplacés l'un vers l'autre en direction de leur position rapprochée, le panneau arrière 4 comporte une portion centrale 17a et deux portions latérales 17b, 17c qui sont disposées de part et d'autre de la portion centrale 17a selon la direction x, comme représenté sur la figure 3. Les portions latérales 17b, 17c sont chacune, d'une part, mobiles en rotation autour d'un axe géométrique parallèle à l'axe z par rapport au panneau latéral 2, 3 auquel ladite portion latérale 17b, 17c est liée et, d'autre part, mobiles en rotation autour d'un axe géométrique parallèle à l'axe z par rapport à ladite portion centrale 17a. Sur la figure 3, les portions latérales 17b, 17c sont chacune reliées à l'un des panneaux latéraux 2, 3 par une ou plusieurs charnières 20 de manière à assurer la rotation desdites portions latérales 17b, 17c par rapport aux panneaux latéraux 2, 3. En outre, chacune des portions latérales 17b, 17c est reliée à la portion centrale 17a par une ligne de pliure 18, 19 assurant un degré de liberté en rotation desdites portions latérales 17b, 17c par rapport à la portion centrale 17a. A titre d'exemple, les lignes de pliures 18, 19 sont formées par un amincissement de matière le long d'une ligne parallèle à l'axe Z et sont réalisées lors du moulage du panneau arrière 4.The rear panel 4 is made of a rigid plastic material, such as polyethylene or polyvinyl. In order to allow its deformation along the x axis when the side panels 2, 3 are moved towards one another in the direction of their close position, the rear panel 4 comprises a central portion 17a and two side portions 17b, 17c which are arranged on either side of the central portion 17a in the x direction, as shown in figure 3 . The side portions 17b, 17c are each, on the one hand, movable in rotation about a geometric axis parallel to the z axis relative to the side panel 2, 3 to which said side portion 17b, 17c is linked and, of on the other hand, movable in rotation about a geometric axis parallel to the z axis with respect to said central portion 17a. On the figure 3 , the side portions 17b, 17c are each connected to one of the side panels 2, 3 by one or more hinges 20 so as to ensure the rotation of said side portions 17b, 17c relative to the side panels 2, 3. In addition, each of the lateral portions 17b, 17c is connected to the central portion 17a by a fold line 18, 19 ensuring a degree of freedom in rotation of said lateral portions 17b, 17c relative to the central portion 17a. By way of example, the fold lines 18, 19 are formed by thinning of material along a line parallel to the Z axis and are produced during the molding of the rear panel 4.

Dans d'autres modes de réalisation, les articulations entre les panneaux latéraux 2, 3 et les portions latérales 17b, 17c du panneau arrière 4 sont réalisées au moyen de lignes de pliure. De même, dans d'autres modes de réalisation, chaque articulation entre l'une des portions latérales 17b, 17c et la portion centrale 17a est susceptible d'être réalisée au moyens d'une ou de plusieurs charnières.In other embodiments, the joints between the side panels 2, 3 and the side portions 17b, 17c of the rear panel 4 are made by means of fold lines. Likewise, in other embodiments, each articulation between one of the lateral portions 17b, 17c and the central portion 17a is capable of being produced by means of one or more hinges.

La valise 1 comporte en outre un dispositif de préhension 21 qui est fixé sur la portion centrale 17a du panneau arrière 4. Le dispositif de préhension 21 comporte une poignée 12 qui est fixée à l'extrémité d'un manche télescopique. Le manche télescopique est quant à lui logé dans un fourreau 23 qui est fixé sur la portion centrale 17a du panneau arrière 4. Lorsque le manche télescopique est dans un état rétracté, la poignée 12 s'étend légèrement au-dessus du bord supérieur des panneaux latéraux 2, 3 de manière à ce que ladite poignée 12 n'interfère pas avec les panneaux latéraux 2, 3 lors de leur mouvement en direction de leur position rapprochée.The case 1 further comprises a gripping device 21 which is fixed to the central portion 17a of the rear panel 4. The gripping device 21 comprises a handle 12 which is fixed to the end of a telescopic handle. The telescopic handle is itself housed in a sheath 23 which is fixed to the central portion 17a of the rear panel 4. When the telescopic handle is in a retracted state, the handle 12 extends slightly above the upper edge of the panels. side panels 2, 3 so that said handle 12 does not interfere with side panels 2, 3 during their movement towards their close position.

Dans le mode de réalisation représenté, les panneaux supérieur 7 et inférieur 8 sont ajourés de manière à limiter le poids de la valise 1. Dans ce cas, lesdits panneaux supérieur 7 et inférieur 8 sont recouverts d'un revêtement en tissu de manière à garantir que l'espace interne de rangement soit clos.In the embodiment shown, the upper 7 and lower 8 panels are perforated so as to limit the weight of the case 1. In this case, said upper 7 and lower 8 panels are covered with a fabric covering so as to guarantee that the internal storage space is closed.

La valise 1 comporte en outre un élément arrière en tissu 24 qui présente une portion rectangulaire qui recouvre le panneau arrière 4 et le fourreau 23 du dispositif de préhension 21 et permet ainsi de dissimuler ledit fourreau 23. L'élément arrière en tissu 24 est fixé au niveau de ses deux bords latéraux aux panneaux latéraux 2, 3. L'élément arrière en tissu 24 comporte également deux portions triangulaires qui recouvrent respectivement le panneau supérieur 7 et le panneau inférieur 6 lorsque la valise 1 est dans sa configuration dépliée d'utilisation. La valise 1 comporte également deux éléments supérieur et inférieur en tissu 25 présentant une échancrure correspondant aux portions triangulaires de l'élément arrière en tissu 24 et qui sont chacun fixés, par exemple par couture, à la portion triangulaire adjacente de l'élément arrière en tissu 24. Les deux éléments supérieur et inférieur de tissu 25 sont également fixés aux panneaux latéraux 2, 3 et au panneau avant 5. Par conséquent, l'élément arrière en tissu 24 ainsi que les éléments supérieur et inférieur en tissu 25 forment avec le panneau avant 5 une enveloppe souple permettant de conserver l'espace interne de rangement clos lorsque les panneaux inférieur 6 et supérieur 7 sont dans leur position escamotée et, permettant, par conséquent de dissimuler notamment les panneaux inférieur 6 et supérieure 7, leur articulation et les dispositifs de verrouillage desdits panneaux inférieur 6 et supérieur 7.The suitcase 1 further comprises a rear fabric element 24 which has a rectangular portion which covers the rear panel 4 and the sleeve 23 of the gripping device 21 and thus makes it possible to conceal said sleeve 23. The rear fabric element 24 is fixed. at the level of its two side edges to the side panels 2, 3. The rear fabric element 24 also comprises two triangular portions which respectively cover the upper panel 7 and the lower panel 6 when the suitcase 1 is in its unfolded configuration of use . The suitcase 1 also comprises two upper and lower fabric elements 25 having a cutout corresponding to the triangular portions of the rear fabric element 24 and which are each fixed, for example by sewing, to the adjacent triangular portion of the rear element in fabric 24. The two upper and lower fabric elements 25 are also secured to the side panels 2, 3 and the front panel 5. Therefore, the rear fabric element 24 as well as the upper and lower fabric elements 25 form together with the fabric. front panel 5 a flexible envelope making it possible to keep the internal storage space closed when the lower 6 and upper 7 panels are in their retracted position and, consequently allowing, in particular to conceal the lower 6 and upper 7 panels, their articulation and the locking devices of said lower 6 and upper 7 panels.

La valise 1 comporte en outre une poignée 16 qui est fixée sur le morceau de tissu 25 recouvrant le panneau supérieur 7.The case 1 further comprises a handle 16 which is fixed to the piece of fabric 25 covering the top panel 7.

Alternatively, the other side panel 3 may also have a handle. rigid outer shell and a rigid inner shell, fixed one inside the other.

Selon un mode de réalisation, la liaison entre les panneaux latéraux 2, 3 et, les éléments souples, tel que le panneau avant 5, l'élément arrière en tissu 24 et les éléments inférieur et supérieur en tissu 25 est assurée en pinçant les bords desdits éléments souples entre les deux coques externe et interne de chacun des panneaux latéraux 2, 3. De manière alternative, cette liaison peut être assurée par thermocollage et/ou ou par couture.According to one embodiment, the connection between the side panels 2, 3 and the flexible elements, such as the front panel 5, the rear fabric element 24 and the lower and upper fabric elements 25 is provided by pinching the edges. of said flexible elements between the two outer and inner shells of each of the side panels 2, 3. Alternatively, this connection can be provided by heat sealing and / or or by stitching.

La valise 1 est également équipée d'un jeu de quatre mécanismes à roulette 8 permettant de déplacer la valise 1. Deux des mécanismes à roulette 8 sont fixés sur l'extrémité inférieure du panneau latéral 2 tandis que les deux autres sont fixés sur l'extrémité inférieure de l'autre panneau latéral 3. La fixation des mécanismes à roulette 8 sur les panneaux latéraux 2, 3 rigides permet d'assurer une fixation des roulettes dans un même plan, sur des zones rigides, quelle que soit la configuration de la valise 1. Chacun de mécanisme à roulette 8 comporte un axe assurant la rotation de sa roulette selon un axe parallèle à l'axe x et, de préférence assure également une rotation de l'axe de rotation des roulettes autour d'un axe parallèle à l'axe z.The case 1 is also equipped with a set of four roller mechanisms 8 for moving the case 1. Two of the roller mechanisms 8 are attached to the lower end of the side panel 2 while the other two are attached to the. lower end of the other side panel 3. The fixing of the roller mechanisms 8 on the rigid side panels 2, 3 makes it possible to secure the castors in the same plane, on rigid areas, whatever the configuration of the suitcase 1. Each of the roller mechanism 8 comprises an axis ensuring the rotation of its wheel along an axis parallel to the x axis and, preferably also ensuring a rotation of the axis of rotation of the wheels about an axis parallel to the z axis.

De manière avantageuse, la valise 1 comporte en outre un dispositif de verrouillage, illustré sur les figures 4 à 6, agencé pour assurer, dans un état actif, le maintien des panneaux supérieur 7 et inférieur 6 dans leur position déployée. La description ci-dessous est faîte en relation avec le dispositif de verrouillage du panneau inférieur 6. Toutefois, le dispositif de verrouillage du panneau supérieur 7 présente une structure identique.Advantageously, the suitcase 1 further comprises a locking device, illustrated in the figures 4 to 6 , arranged to ensure, in an active state, the maintenance of the upper 7 and lower 6 panels in their deployed position. The The description below is given in relation to the lower panel locking device 6. However, the upper panel locking device 7 has an identical structure.

Les panneaux latéraux 2 et 3 comportent chacun un rebord 30 faisant saillie selon l'axe X, en direction de l'autre panneau latéral 2, 3. Ce rebord 30 forme une surface d'appui contre laquelle vient reposer l'extrémité distale 38 du panneau inférieur 6 lorsqu'il est dans sa position déployée. Comme représenté sur la figure 4, ce rebord 30 est susceptible d'être recouvert d'un élément en mousse 31 dans la portion destinée à recevoir l'extrémité distale 38 dudit panneau inférieur 6. Cette mousse 31 permet notamment d'amortir les bruits et de limiter les jeux entre le panneau inférieur 6 et son dispositif de verrouillage.The side panels 2 and 3 each comprise a flange 30 projecting along the X axis, in the direction of the other side panel 2, 3. This flange 30 forms a bearing surface against which the distal end 38 of the device rests. lower panel 6 when in its deployed position. As shown on figure 4 , this rim 30 is capable of being covered with a foam element 31 in the portion intended to receive the distal end 38 of said lower panel 6. This foam 31 makes it possible in particular to dampen noise and limit the clearances between the lower panel 6 and its locking device.

Le dispositif de verrouillage comporte une poignée de butée 32 montée pivotante selon un axe parallèle à l'axe y entre une position inactive, représentée sur la figure 4, dans laquelle elle autorise le pivotement dudit panneau inférieur 6 entre sa position escamotée et sa position déployée et une position active dans laquelle elle plaque l'extrémité distale 38 du panneau inférieur 6 contre le rebord 30 du panneau latéral 2 et empêche ainsi le mouvement dudit panneau inférieur 6 en direction de sa position escamotée.The locking device comprises a stop handle 32 pivotally mounted along an axis parallel to the y axis between an inactive position, shown in FIG. figure 4 , in which it allows the pivoting of said lower panel 6 between its retracted position and its deployed position and an active position in which it presses the distal end 38 of the lower panel 6 against the rim 30 of the side panel 2 and thus prevents the movement of said lower panel 6 in the direction of its retracted position.

Dans le mode de réalisation représenté, le panneau inférieur 6 est équipé d'un taquet 35, notamment représenté sur les figures 5 et 6 faisant saillie vers l'espace interne de rangement et contre laquelle la poignée de butée 32 vient en butée lorsqu'elle est dans sa position active. Le taquet 35 et la poignée de butée 32 sont dimensionnées de telle sorte qu'ils frottent l'un contre l'autre lorsque la poignée de butée 32 est dans sa position active, ce qui assure un verrouillage du dispositif. En effet, l'utilisateur doit exercer un effort suffisant pour vaincre les efforts de frottement en vue de déplacer la poignée de butée 32 de sa position active vers sa position non active.In the embodiment shown, the lower panel 6 is equipped with a stopper 35, in particular shown in the figures 5 and 6 projecting towards the internal storage space and against which the stop handle 32 abuts when it is in its active position. The stopper 35 and the stopper handle 32 are dimensioned such that they rub against each other when the stopper handle 32 is in its active position, which ensures a locking of the device. Indeed, the user must exert a sufficient effort to overcome the friction forces in order to move the stop handle 32 from its active position to its inactive position.

De manière avantageuse, comme représenté sur la figure 4, chaque panneau inférieur 6 et supérieur 7 est équipé d'une poignée 34 permettant à l'utilisateur de manœuvrer le panneau inférieur 6 ou supérieur 7 afin de les faire pivoter entre leurs positions déployée et escamotée.Advantageously, as shown in figure 4 , each lower 6 and upper 7 panel is equipped with a handle 34 allowing the user to maneuver the lower 6 or upper panel 7 in order to make them pivot between their deployed and retracted positions.
