Description

Bagage à structure pliable  Foldable luggage
L'invention est relative à un bagage à structure pliable, entre une conformation repliée de volume réduit de rangement ou de stockage et une conformation développée de volume d'utilisation. The invention relates to a luggage with foldable structure, between a folded conformation of reduced storage or storage volume and a developed configuration of volume of use.
L'invention est particulièrement utile dans son application à la construction de bagages à quatre roulettes munis d'une poignée télescopique.  The invention is particularly useful in its application to the construction of luggage with four wheels provided with a telescopic handle.
Actuellement, on ne connaît pas de système de bagage à structure pliable, permettant de faire varier le volume d'un bagage à quatre roulettes et à poignée télescopique de manière satisfaisante.  Currently, there is no known baggage system foldable structure, to vary the volume of a luggage with four wheels and telescopic handle satisfactorily.
Les bagages à roulettes et à poignée télescopique sont généralement constitués d'un plancher et de cadres latéraux combinés avec une feuille en polypropylène présentant une conformation en C.  Wheeled luggage and telescopic handgrips generally consist of a floor and side frames combined with a polypropylene sheet having a C-shaped conformation.
Cette conception du plancher et des cadres latéraux permet de maintenir l'écartement, la rigidité et la coplanarité des quatre roues, tout en permettant une bonne efficacité de guidage à l'aide de la poignée télescopique.  This design of the floor and side frames maintains the spacing, stiffness and coplanarity of the four wheels, while allowing a good guiding efficiency with the telescopic handle.
Le document WO2013/028974 décrit un bagage repliable, comprenant une surface inférieure, qui comprend une partie avant rigide et une partie arrière rigide. Ces dites parties avant et arrière rigides sont reliées de manière à se déplacer d'une configuration sensiblement coplanaire à une configuration sensiblement perpendiculaire. Un mécanisme de verrouillage est agencé pour verrouiller lesdites parties avant et arrière rigides dans ladite configuration sensiblement coplanaire. Ce bagage repliable comprend une surface supérieure, comprenant une partie avant et une partie arrière. Ladite partie avant et ladite partie arrière de surface supérieure sont disposées de façon à pouvoir passer d'une configuration sensiblement coplanaire à une configuration sensiblement perpendiculaire. Ce bagage repliable comprend une surface arrière, une surface latérale gauche, une surface latérale droite, et une surface avant. Le bagage peut être dans une configuration déployée, en fonctionnement, et peut être dans une configuration repliée de rangement ou de stockage. Dans ladite configuration déployée, lesdites parties avant et arrière de la surface de fond sont verrouillées dans ladite configuration sensiblement coplanaire, et lesdites parties avant et arrière de la surface supérieure sont positionnées dans ladite configuration sensiblement coplanaire. Dans ladite configuration repliée, lesdites parties avant et arrière de la surface de fond sont disposées dans ladite configuration sensiblement perpendiculaire, et lesdites parties avant et arrière de la surface supérieure sont positionnés dans ladite configuration sensiblement perpendiculaire. WO2013 / 028974 discloses a collapsible luggage, comprising a lower surface, which comprises a rigid front portion and a rigid rear portion. These rigid front and rear portions are connected so as to move from a substantially coplanar configuration to a substantially perpendicular configuration. A locking mechanism is arranged to lock said rigid front and rear portions in said substantially coplanar configuration. This collapsible luggage comprises an upper surface, comprising a front portion and a rear portion. Said front portion and said upper surface rear portion are arranged to be able to move from a substantially coplanar configuration to a substantially perpendicular configuration. This collapsible luggage includes a back surface, a left side surface, a right side surface, and a front surface. The luggage may be in an expanded configuration, in use, and may be in a collapsed storage or storage configuration. In said expanded configuration, said front and rear portions of the bottom surface are locked in said substantially coplanar configuration, and said front and rear portions of the upper surface are positioned in said substantially coplanar configuration. In said folded configuration, said front and rear portions of the bottom surface are disposed in said configuration substantially perpendicular, and said front and rear portions of the upper surface are positioned in said substantially perpendicular configuration.
Le mécanisme de verrouillage du bagage repliable décrit dans le document WO2013/028974 est situé sur le milieu de la surface inférieure, de sorte que les transmissions d'effort sur les côtés, c'est-à-dire entre les deux roues avant et arrière de gauche et les deux roues avant et arrière de droite, sont déséquilibrées.  The folding luggage locking mechanism described in WO2013 / 028974 is located on the middle of the lower surface, so that the force transmissions on the sides, that is to say between the two front and rear wheels left and the two right front and rear wheels are out of balance.
Ce système de verrouillage présenté n'est pas satisfaisant, car il ne permet pas un verrouillage suffisant des parties avant et arrière rigides l'une par rapport à l'autre, pour des charges importantes.  This locking system presented is not satisfactory, because it does not allow sufficient locking of the front and rear rigid parts relative to each other, for large loads.
Ce système de verrouillage présenté n'est pas plus satisfaisant pour résister à un test de jet, car les parties avant et arrière rigides ne restent pas coplanaires.  This locking system presented is not more satisfactory to withstand a jet test, because the rigid front and rear parts do not remain coplanar.
Ce système de verrouillage présenté n'est enfin pas satisfaisant lors du roulage, car les parties avant et arrière rigides ne restent également pas coplanaires, d'où il résulte que les transmissions d'effort du haut vers le bas du produit sont imparfaites et que le roulage est imparfait.  This locking system presented is finally not satisfactory when driving, because the rigid front and rear parts also do not remain coplanar, resulting in the transmission of effort from the top to the bottom of the product are imperfect and that the rolling is imperfect.
Un premier but de l'invention est de proposer un nouveau bagage à structure pliable, dont la structure permet une application aux bagages à roulettes et aux bagages sans roulettes.  A first object of the invention is to provide a new bag with foldable structure, the structure allows an application to luggage on wheels and baggage without wheels.
Un deuxième but de l'invention est de proposer un nouveau bagage à structure pliable, de structure légère et présentant une bonne qualité de roulage et une stabilité comparable aux bagages à structure non pliable.  A second object of the invention is to provide a new luggage with foldable structure, lightweight structure and having a good quality of rolling and stability comparable to non-foldable luggage structure.
Un troisième but de l'invention est de proposer un nouveau bagage à structure pliable dont le volume choisi peut être maintenu, même en cours de roulage.  A third object of the invention is to provide a new bag with foldable structure whose chosen volume can be maintained, even while driving.
L'invention a pour objet un bagage à structure pliable entre une conformation de volume réduit de rangement ou de stockage et une conformation développée de volume d'utilisation, du type comportant une face d'accès et un fond opposé à ladite face d'accès, ledit fond étant bordé par quatre faces latérales, caractérisé en combinaison par le fait qu'une face latérale présente une structure pliable et apte à être maintenue rigidement par au moins un moyen latéral de maintien. Du fait que la structure pliable est apte à être maintenue rigidement par des moyens latéraux de maintien, la stabilité de roulage et la coplanarité des roulettes peuvent être obtenues dans une application de l'invention à la construction de bagages à roulettes. The subject of the invention is a baggage with a foldable structure between a conformation of a reduced storage or storage volume and an expanded configuration of use volume, of the type comprising an access face and a bottom opposite said access face. , said bottom being bordered by four lateral faces, characterized in combination by the fact that a lateral face has a foldable structure and able to be held rigidly by at least one lateral holding means. Because the foldable structure is able to be held rigidly by lateral holding means, the rolling stability and the coplanarity of the rollers can be obtained in an application of the invention to the construction of luggage on wheels.
Selon d'autres caractéristiques alternatives de l'invention :  According to other alternative features of the invention:

L'invention sera mieux comprise grâce à la description qui va suivre donnée à titre d'exemple non limitatif, en référence aux dessins annexés dans lesquels :  The invention will be better understood from the following description given by way of nonlimiting example, with reference to the appended drawings in which:
La figure 1 représente schématiquement une vue en perspective d'un bagage à structure pliable selon l'invention en conformation repliée de volume réduit de rangement ou de stockage.  Figure 1 schematically shows a perspective view of a bag of foldable structure according to the invention in folded conformation of reduced storage volume or storage.

La figure 4 représente schématiquement une vue partielle en perspective illustrant un moyen de verrouillage d'un bagage à structure pliable selon l'invention en conformation développée de volume d'utilisation.  FIG. 4 schematically represents a partial perspective view illustrating a locking means of a luggage with a foldable structure according to the invention in a developed configuration of use volume.
En référence aux figures 1 à 4, les éléments identiques ou fonctionnellement équivalents sont repérés par des chiffres de référence identiques.  With reference to FIGS. 1 to 4, identical or functionally equivalent elements are identified by identical reference numerals.
La structure du bagage à structure pliable selon l'invention décrite en référence aux figures 1 à 4 est particulièrement avantageuse pour la construction de bagages à quatre roulettes, de manière à assurer une qualité de roulage dans toutes les conformations correspondant à un volume donné, tout en conservant les propriétés de résistance aux chocs, à l'utilisation et au portage des bagages à roulettes à structure non pliable de l'art antérieur.  The structure of the baggage folding structure according to the invention described with reference to Figures 1 to 4 is particularly advantageous for the construction of luggage with four wheels, so as to ensure a rolling quality in all conformations corresponding to a given volume, while retaining the impact resistance, use and carrying properties of non-foldable wheeled luggage of the prior art.
L'invention permet de faire varier le volume d'un bagage à roulettes, de manière simple et ergonomique, sans démontage et sans manipulation particulière, de plier le plancher pour le rangement ou le stockage, et de fournir un plancher rigide et continu pour le roulage. Cette variation de volume permet de réduire l'épaisseur du bagage en vue de son rangement lorsqu'il n'est pas utilisé.  The invention makes it possible to vary the volume of a wheeled luggage, in a simple and ergonomic manner, without disassembly and without particular handling, to fold the floor for storage or storage, and to provide a rigid and continuous floor for the rolling. This change in volume reduces the thickness of the luggage for storage when not in use.
En mode d'utilisation, le plancher pliable ne s'affaisse pas sous le poids de la charge, notamment au niveau de l'axe de pliage : l'invention permet ainsi de garantir l'assemblage d'un système à quatre roues sur le plancher et de garantir un roulage parfait en mode à quatre roues. In use mode, the foldable floor does not sag under the weight of the load, particularly at the level of the folding axis: the invention thus makes it possible to guarantee the assembly of a four-wheel system on the floor and guarantee a perfect ride in four-wheel mode.
Sur la figure 1, un bagage à structure pliable selon l'invention est un bagage à roulettes R et à poignée télescopique T, comportant un fond 1, un plancher 2 et un plafond 3.  In FIG. 1, a luggage with a foldable structure according to the invention is a wheeled luggage R with a telescopic handle T, comprising a bottom 1, a floor 2 and a ceiling 3.
Deux faces latérales 4 s'étendent à partir du fond 1, entre le plancher 2 et le plafond 3  Two lateral faces 4 extend from the bottom 1, between the floor 2 and the ceiling 3
Une face d'accès 5 par fermeture à glissière est opposée au fond 1 et borde les faces latérales 4, le plancher 2 et le plafond 3.  A zipper access surface 5 is opposed to the bottom 1 and borders the lateral faces 4, the floor 2 and the ceiling 3.
Le plancher 2 est un plancher pliable entre une conformation de volume réduit de rangement ou de stockage du bagage représentée à la figure 1 et une conformation de grand volume représentée à la figure 2.  The floor 2 is a foldable floor between a reduced volume configuration of storage or storage of luggage shown in Figure 1 and a large volume conformation shown in Figure 2.
Le plancher 2 comporte deux parties : une partie avant 2a rigide et une partie arrière 2b rigide articulées par une charnière 2c.  The floor 2 comprises two parts: a rigid front portion 2a and a rigid rear portion 2b articulated by a hinge 2c.
La charnière 2c peut être réalisée par couture d'enveloppes textiles solidarisées aux parties rigides 2a et 2b du plancher 2, de sorte que la partie avant peut effectuer une rotation vers l'intérieur du produit.  The hinge 2c can be made by sewing textile envelopes secured to the rigid parts 2a and 2b of the floor 2, so that the front portion can rotate inwardly of the product.
Les parties rigides 2a et 2b du plancher 2 sont repliées sensiblement à angle droit dans la conformation de volume réduit de rangement ou de stockage, pour réduire l'épaisseur du plancher 2.  The rigid portions 2a and 2b of the floor 2 are bent substantially at right angles in the configuration of reduced storage or storage volume, to reduce the thickness of the floor 2.
Les parties rigides 2a et 2b du plancher 2 sont munies chacune de deux roulettes R disposées latéralement au voisinage des faces latérales 4.  The rigid parts 2a and 2b of the floor 2 are each provided with two rollers R arranged laterally adjacent the lateral faces 4.
La partie avant 2a du plancher 2 est ainsi une partie rigide, qui porte deux boîtiers 6 de support de roulette R.  The front part 2a of the floor 2 is thus a rigid part, which carries two casings 6 of roulette support R.
La partie arrière 2b du plancher 2 est aussi une partie rigide qui porte deux autres boîtiers 6 de support de roulette R.  The rear part 2b of the floor 2 is also a rigid part which carries two other casings 6 of roulette support R.
Le plafond 3 du bagage à roulettes R et à poignée télescopique T est généralement constitué avec une feuille en polypropylène présentant une conformation en C prolongeant le fond 1 et en constituant le retour. Le plafond 3 présente une ouverture permettant le montage de la poignée télescopique T.  The ceiling 3 of the wheeled luggage R and telescopic handle T is generally made of a polypropylene sheet having a C-shaped extension extending the bottom 1 and constituting the return. The ceiling 3 has an opening for mounting the telescopic handle T.
L'invention s'étend également à une variante non représentée de bagage avec plafond 3 pliable entre une conformation de volume réduit de rangement ou de stockage du bagage représentée à la figure 1 et une conformation de grand volume représentée à la figure 2. Le plafond 3 de cette variante non représentée de bagage à structure pliable selon l'invention peut comporter à cet effet une partie avant et une partie arrière pouvant être repliées sensiblement à angle droit dans la conformation de volume réduit de rangement ou de stockage. Les parties avant et arrière du plafond 3 peuvent être complémentaires du côté des faces latérales 4, pour constituer un plafond 3 sensiblement rigide. The invention also extends to an unrepresented variant of baggage with a folding ceiling 3 between a low volume configuration of storage or storage of the baggage shown in FIG. 1 and a large volume conformation shown in FIG. 3 of this variant, not shown, of luggage with a foldable structure according to the invention may comprise for this purpose a front portion and a rear portion that can be folded substantially at right angles in the conformation of reduced storage volume or storage. The front and rear parts of the ceiling 3 may be complementary side side 4, to form a substantially rigid ceiling 3.
Les faces latérales 4 s'étendant à partir du fond 1, entre le plancher 2 et le plafond 3 sont associées à des panneaux 4a de rigidification aptes à pivoter vers le fond du bagage.  The side faces 4 extending from the bottom 1, between the floor 2 and the ceiling 3 are associated with stiffening panels 4a able to pivot towards the bottom of the luggage.
Ces panneaux pivotants 4a rigides sont montés à l'intérieur de la structure du bagage à structure pliable, pour constituer des cadres de rigidification dans la conformation de grand volume représentée à la figure 2.  These rigid pivoting panels 4a are mounted inside the structure of the luggage with folding structure, to constitute stiffening frames in the large volume conformation shown in FIG.
Les panneaux 4a de rigidification sont fixés sur l'arrière ou fond 1 du bagage à structure pliable et ne sont pas fixés sur leurs autres côtés, pour pouvoir effectuer une rotation et pour se replier à l'intérieur de la structure du bagage à structure pliable.  The stiffening panels 4a are fixed on the rear or bottom 1 of the luggage with foldable structure and are not fixed on their other sides, to be able to rotate and to fold inside the structure of the baggage foldable structure .
Ces panneaux 4a de rigidification pivotent ainsi à l'intérieur de la structure du bagage à structure pliable, dans la conformation de volume réduit de rangement ou de stockage du bagage représentée à la figure 1.  These stiffening panels 4a thus pivot inside the structure of the luggage with foldable structure, in the reduced volume configuration of storage or storage of the luggage represented in FIG.
La paire de panneaux pivotants 4a rigides sont ainsi repliés l'un sur l'autre dans la conformation de volume réduit de rangement ou de stockage du bagage 1 représentée à la figure 1.  The pair of rigid pivoting panels 4a are thus folded over one another in the reduced volume configuration of storage or storage of the luggage 1 shown in FIG.
Les panneaux 4a de rigidification sont réalisés au moyen d' une enveloppe textile et sont de préférence bordés par des cadres continus rigides assurant leur maintien et leur absence de déformation à l'intérieur du bagage à structure pliable.  The stiffening panels 4a are made by means of a textile envelope and are preferably bordered by rigid continuous frames ensuring their maintenance and their absence of deformation inside the luggage with foldable structure.
L'invention décrite en référence à un bagage à structure pliable à quatre roulettes R et à poignée télescopique T s'étend également aux valises à deux roues avec ou sans cadres latéraux et à des bagages à structure pliable souples de type polochon. Les panneaux 4a de rigidification peuvent comporter d'autres éléments que des cadres latéraux, par exemple des tiges en fibre de verre, démontables ou non.  The invention described with reference to a foldable structure luggage with four wheels R and telescopic handle T also extends to two-wheeled suitcases with or without side frames and flexible foldable luggage bag type duffel. The stiffening panels 4a may comprise other elements than lateral frames, for example fiberglass rods, removable or not.
Sur la figure 2, le bagage à structure pliable 1 selon l'invention est représenté dans une conformation de grand volume d'utilisation.  In FIG. 2, the luggage with foldable structure 1 according to the invention is represented in a conformation of large volume of use.
Dans cette conformation de grand volume d'utilisation, la partie avant 2a est coplanaire avec la partie arrière 2b du plancher 2.  In this conformation of large volume of use, the front portion 2a is coplanar with the rear portion 2b of the floor 2.
Les parties avant 2a et arrière 2b sont reliées par l'articulation 2c. Des moyens 2d latéraux de verrouillage sont montés alternativement sur la partie avant 2a ou la partie arrière 2b, au voisinage des boîtiers 6 de support de roulette R. The front portions 2a and 2b are connected by the hinge 2c. Lateral locking means 2d are alternately mounted on the front part 2a or the rear part 2b, in the vicinity of the casing support casings R.
Les emplacements des moyens 2d latéraux de verrouillage sont ménagés de préférence dans les parties internes 6a des boîtiers 6 de support de roulette R.  The locations of the lateral locking means 2d are preferably arranged in the internal parts 6a of the casings 6 of the R carrier.
Les moyens 2d latéraux de verrouillage peuvent être constituées en tout matériau rigide, par exemple en fibre de verre, en acier, ou en plastique rigide.  The lateral locking means 2d can be made of any rigid material, for example fiberglass, steel, or rigid plastic.
L'écartement des moyens 2d latéraux de verrouillage de la partie avant 2a et de la partie arrière 2b du plancher 2 permet d'éviter les concentrations de contraintes au milieu du plancher 2. On évite ainsi de constituer une flexion déviée au milieu du plancher 2, et de déformer le plan de roulage au niveau des emplacements des boîtiers 6 de support de roulette R, du fait que l'on répartit les efforts sur une plus grande largeur, correspondant aux bordures intérieures du plancher 2.  The spacing of the lateral locking means 2d of the front part 2a and of the rear part 2b of the floor 2 makes it possible to avoid the stress concentrations in the middle of the floor 2. It is thus avoided to constitute a deflection deflected in the middle of the floor 2 , and to deform the rolling plane at the locations of casings R of caster support 6, as the forces are distributed over a wider width, corresponding to the inner edges of the floor 2.
En conformation de grand volume d'utilisation, l'avant de chaque panneau 4a de rigidification est fixé et maintenu à un bord avant de face latérale 4 par une bande Velcro (marque déposée) ou par des boutons-pression.  In conformation of large volume of use, the front of each panel 4a stiffening is fixed and maintained at a front edge of side face 4 by a Velcro (registered trademark) or by snaps.
L'arrière de chaque panneau 4a de rigidification est fixé et maintenu à l'arrière de chaque face latérale 4 par une charnière 4c, qui peut être réalisée par couture d'enveloppe textile solidarisée à l'arrière de chaque face latérale 4.  The rear of each stiffening panel 4a is fixed and held at the rear of each side face 4 by a hinge 4c, which can be made by sewing textile envelope secured to the rear of each side face 4.
Dans le mouvement de déplacement vers une conformation de grand volume, chaque panneau 4a de rigidification est guidé par la charnière 4c solidarisée à l'arrière de chaque face latérale 4. Les panneaux pivotants 4a rigides s'ouvrent ainsi vers l'extérieur en étant articulés sur la face arrière du bagage, de sorte que les panneaux pivotants 4a rigides adoptent des positions sensiblement parallèles dans la conformation de grand volume.  In the displacement movement towards a conformation of large volume, each rigidification panel 4a is guided by the hinge 4c secured to the rear of each lateral face 4. The rigid pivoting panels 4a thus open outwardly by being articulated on the back side of the luggage, so that the rigid pivoting panels 4a adopt substantially parallel positions in the large volume conformation.
Du fait qu'au moins une de deux faces latérales est associée à au moins un panneau de rigidification apte à pivoter vers le fond du bagage pliable, les transmissions d'effort du haut vers le bas du produit sont régulièrement transmises et le roulage est amélioré.  Since at least one of two lateral faces is associated with at least one stiffening panel capable of pivoting towards the bottom of the foldable baggage, the transmission of effort from the top to the bottom of the product is regularly transmitted and the rolling is improved. .
Ainsi, grâce à l'invention, le bagage à structure pliable présente une structure stable et rigide dans la conformation de grand volume : en effet, les parties latérales 4 sont stabilisées par les panneaux pivotants 4a rigides dans la conformation de grand volume. Sur la figure 3, un moyen de verrouillage d'un bagage à structure pliable selon l'invention en conformation repliée de volume réduit de rangement ou de stockage est représenté . Thus, thanks to the invention, the luggage with foldable structure has a stable and rigid structure in the large volume conformation: in fact, the lateral portions 4 are stabilized by the rigid pivoting panels 4a in the large volume conformation. In Figure 3, a locking means of a foldable structure luggage according to the invention in folded conformation of reduced storage or storage volume is shown.
Les parties avant 2a et arrière 2b sont reliées par l'articulation 2c.  The front portions 2a and 2b are connected by the hinge 2c.
Des moyens 2d latéraux de verrouillage sont montés dans cet exemple sur la partie arrière 2b, au voisinage des boîtiers 6 de support de roulette R.  Lateral locking means 2d are mounted in this example on the rear part 2b, in the vicinity of the casings R of caster R.
Les emplacements des moyens 2d latéraux de verrouillage sont ménagés et directement intégrés dans les parties internes 6a des boîtiers 6 de support de roulette R.  The locations of the lateral locking means 2d are formed and directly integrated into the inner parts 6a of the casings R of caster R.
Les moyens 2d latéraux de verrouillage comportent des éléments allongés The lateral locking means 2d comprise elongated elements
7 en matériau rigide, par exemple en fibre de verre, en acier, ou en plastique rigide. 7 in rigid material, for example fiberglass, steel, or rigid plastic.
Les éléments allongés 7 en matériau rigide sont montés à rotation entre une position libre sensiblement parallèle au fond 1 et une position forcée sensiblement perpendiculaire au fond 1.  The elongated elements 7 of rigid material are rotatably mounted between a free position substantially parallel to the bottom 1 and a forced position substantially perpendicular to the bottom 1.
Dans la position libre sensiblement parallèle au fond 1, les éléments allongés 7 en matériau rigide ne dépassent pas la ligne de l'articulation 2c.  In the free position substantially parallel to the bottom 1, the elongate elements 7 of rigid material do not exceed the line of the articulation 2c.
Dans le cas d'une pluralité d'éléments allongés 7 en matériau rigide, les éléments allongés 7 en matériau rigide peuvent être articulés sur l'avant ou sur l'arrière du plancher 2 d'un bagage à structure pliable selon l'invention.  In the case of a plurality of elongate elements 7 made of rigid material, the elongated elements 7 of rigid material may be articulated on the front or rear of the floor 2 of a baggage folding structure according to the invention.
Lorsque les éléments allongés 7 en matériau rigide sont articulés sur l'arrière, comme représenté, les panneaux pivotants 4a rigides présentent des conformations échancrées vers le bas, pour autoriser le passage au-dessus des parties internes 6a des boîtiers 6 de support de roulette R du bagage à structure pliable.  When the elongated elements 7 of rigid material are hinged to the rear, as shown, the rigid pivoting panels 4a have notched conformations downwards, to allow the passage over the inner parts 6a of the casings 6 R roulette support luggage with foldable structure.
Lorsque les éléments allongés 7 en matériau rigide sont articulés sur l'avant du bagage à structure pliable, du côté de l'ouverture d'accès 6, les panneaux pivotants 4a rigides peuvent ne comporter pas de conformations échancrées vers l'arrière.  When the elongated elements 7 of rigid material are hinged on the front of the baggage foldable structure, the side of the access opening 6, the pivoting panels 4a rigid may not have notched conformations rearward.
Sur la figure 4, chaque élément allongé 7 en matériau rigide est verrouillé dans deux logements 8a, 8b, de manière à constituer ainsi une liaison rigide de maintien coplanaire des parties avant 2a et arrière 2b reliées par l'articulation 2c.  In FIG. 4, each elongate element 7 made of rigid material is locked in two housings 8a, 8b, so as to constitute a rigid coplanar holding connection of the front 2a and rear 2b parts connected by the hinge 2c.
Les emplacements des logements 8a, 8b sont situés de préférence sur les parties internes 6a des boîtiers 6 de support de roulette R. Cette liaison rigide de maintien coplanaire fournit ainsi une bonne qualité de roulage du bagage à structure pliable à quatre roulettes R et à poignée télescopique T. The locations of the housings 8a, 8b are preferably located on the internal parts 6a of the casings 6 of R roulette support. This rigid coplanar holding connection thus provides good rolling quality of the luggage with foldable structure with four wheels R and telescopic handle T.
Chaque élément allongé 7 en matériau rigide est encastré dans les logements 8a, 8b solidaires des demi-plancher 2a avant et demi-plancher 2b arrière, de sorte qu'aucun effort n'est appliqué sur l'axe de rotation de l'élément allongé 7 en matériau rigide.  Each elongate element 7 made of rigid material is embedded in the housings 8a, 8b integral with the half-floor 2a before and half floor 2b rear, so that no force is applied on the axis of rotation of the elongated element 7 in rigid material.
L'invention couvre également la variante non représentée selon laquelle au moins un élément allongé 7 en matériau rigide est monté à rotation entre une position libre sensiblement parallèle au fond 1 et une position forcée sensiblement perpendiculaire au fond 1 dans le demi-plancher 2a avant.  The invention also covers the variant not shown in which at least one elongate element 7 made of rigid material is rotatably mounted between a free position substantially parallel to the bottom 1 and a forced position substantially perpendicular to the bottom 1 in the floor 2a before floor.
L'invention couvre également la variante non représentée comportant un seul élément allongé 7 en matériau rigide monté à rotation entre une position libre sensiblement parallèle au fond 1 et une position forcée sensiblement perpendiculaire au fond 1.  The invention also covers the variant not shown comprising a single elongated element 7 made of rigid material rotatably mounted between a free position substantially parallel to the bottom 1 and a forced position substantially perpendicular to the bottom 1.
L'invention couvre également la variante non représentée comportant un nombre supérieur à deux d'éléments allongés 7 en matériau rigide montés différemment, pour constituer une liaison rigide de maintien coplanaire des parties avant 2a et arrière 2b de plancher 2.  The invention also covers the variant not shown having a number greater than two of elongate elements 7 of rigid material mounted differently, to form a rigid coplanar holding connection of the front 2a and rear 2b floor 2.
L'essentiel est que l'invention fournisse un moyen latéral de liaison rigide entre une roue avant R et une roue arrière R du même côté. Cette liaison rigide est assurée par les deux tiges 7 de liaison reliant des boîtiers intérieurs 6a de roue et permettant la rigidification du plancher pliable 2. L'invention permet, en position déployée, de relier la roue avant R avec la roue arrière R correspondante, afin de créer un lien rigide entre les deux roues R et d'en assurer la coplanarité.  The essential point is that the invention provides a lateral means of rigid connection between a front wheel R and a rear wheel R of the same side. This rigid connection is provided by the two connecting rods 7 connecting inner wheel housings 6a and allowing stiffening of the foldable floor 2. The invention allows, in the deployed position, to connect the front wheel R with the corresponding rear wheel R, in order to create a rigid link between the two wheels R and to ensure coplanarity.
L'invention prévoit simplement deux tiges ou liens rigides 7, qui relient, en position déployée, directement et de manière rigide une zone proche de la roue avant R avec une zone proche de la roue arrière R correspondante.  The invention simply provides two rods or rigid links 7, which connect, in the deployed position, directly and rigidly an area near the front wheel R with a zone near the corresponding rear wheel R.
Ainsi, au moins une tige 7 effectue une rotation autour d'un point fixe situé à proximité d'une des roues R, et peut ainsi occuper deux positions principales : une position repliée ne reliant pas les boîtiers de roues et parallèle au fond 1 de la valise, et une position déployée venant créer un lien avec une autre roue sur l'autre demi-plancher et perpendiculaire au fond 1 de la valise. L'invention permet ainsi, en position déployée, de garantir une parfaite transmission de l'effort entre l'avant et l'arrière du bagage, et de maintenir les roues avant et arrière dans le même plan, pour assurer un roulage parfait en mode quatre roues. Thus, at least one rod 7 rotates about a fixed point located near one of the wheels R, and can thus occupy two main positions: a folded position not connecting the wheel housings and parallel to the bottom 1 of the bag, and an extended position to create a link with another wheel on the other half floor and perpendicular to the bottom 1 of the bag. The invention thus makes it possible, in the deployed position, to guarantee a perfect transmission of the force between the front and the rear of the luggage, and to keep the front and rear wheels in the same plane, to ensure a perfect running in four wheels.
Dans le mode de réalisation préféré de l'invention, il est prévu de placer le système de tiges 7 à l'intérieur de la valise pliable, d'intégrer le système de fixation, rotation et maintien des tiges 7 directement sur les boîtiers intérieurs 6a de roues à l'intérieur de la valise.  In the preferred embodiment of the invention, it is intended to place the rod system 7 inside the foldable case, to integrate the system for fixing, rotating and holding the rods 7 directly on the inner housings 6a. wheels inside the suitcase.
Un premier boîtier 6a de roue R, par exemple le boîtier arrière au dos de la valise, porte la tige 7 montée autour d'un axe de rotation.  A first wheel housing 6a R, for example the rear housing on the back of the bag, carries the rod 7 mounted about an axis of rotation.
Un logement supplémentaire 8a de coincement de tige 7 en position déployée a été prévu pour éviter la transmission des efforts au point de fixation et à l'axe de rotation de la tige 7.  An additional rod locking housing 8a 7 in the extended position has been provided to prevent the transmission of forces at the point of attachment and the axis of rotation of the rod 7.
Un deuxième boîtier 6a de roue R, par exemple le boîtier avant de la valise, porte un logement 8b qui vient maintenir et verrouiller sur l'autre demi- plancher la tige 7 en position déployée.  A second wheel housing 6a R, for example the front housing of the bag, carries a housing 8b which maintains and lock on the other half floor the rod 7 in the deployed position.
L'invention couvre également la variante non représentée selon laquelle au moins un élément allongé 7 en matériau rigide est intégré à un boîtier 6b extérieur de roue R.  The invention also covers the variant not shown according to which at least one elongated element 7 made of rigid material is integrated in an outer casing 6b of wheel R.
L'invention couvre également la variante non représentée selon laquelle au moins un élément allongé 7 en matériau rigide, non intégré directement sur un boîtier de roue intérieur ou extérieur, est monté à proximité, directement ou au moyen d'une une pièce rapportée, notamment dans le cas d'une fabrication par injection en plusieurs morceaux.  The invention also covers the variant not shown according to which at least one elongate element 7 made of rigid material, not integrated directly on an inner or outer wheel casing, is mounted in proximity, directly or by means of an insert, in particular in the case of a manufacture by injection into several pieces.
Pour mettre en œuvre l'invention, l'utilisateur commence par déplier le plancher 2, puis fixe ensuite les tiges 7 aux boîtiers 6a. Enfin, il effectue la rotation des panneaux pivotants 4a rigides, depuis l'intérieur vers l'extérieur et l'avant du bagage à structure pliable.  To implement the invention, the user begins by unfolding the floor 2, then secures the rods 7 to the housings 6a. Finally, it rotates rigid pivoting panels 4a from the inside to the outside and the front of the foldable luggage.
Lors de ce mouvement de rotation, le bas des panneaux pivotants 4a rigides risque de heurter ou de se bloquer sur les boîtiers 6a de roue, sur les surfaces de logement 8a, 8b dépassant du plancher 2.  During this rotational movement, the bottom of the rigid pivoting panels 4a may hit or lock on the wheel housings 6a, on the housing surfaces 8a, 8b protruding from the floor 2.
Dans le cas où la présence des logements 8a, 8b de maintien de tige 7 sur les boîtiers intérieurs 6a pose des problèmes d'encombrement lors de la manipulation, on prévoit des panneaux pivotants 4a rigides de hauteur légèrement inférieure à la hauteur interne de la valise. Les bas des panneaux pivotants 4a rigides ne touchent pas le bas du produit, et sont échancrés, de manière à passer au-dessus des logements 8a, 8b de boîtiers intérieurs 6a de roue R lors de la rotation In the case where the presence of the rod holding housing 8a, 8b 7 on the inner housings 6a poses congestion problems during handling, rigid pivoting panels 4a are provided with a height slightly less than the internal height of the bag. . The bottom of the rigid pivoting panels 4a do not touch the bottom of the product, and are indented, so as to pass over the housings 8a, 8b of inner casings 6a of wheel R during rotation
Dans ce cas, chaque boîtier intérieur 6a de roue R comprend un rebord 9 surélevé de contre-appui de cadre rigide de panneau pivotant 4a. Ce rebord 9 permet non seulement de maintenir correctement un cadre rigide de panneau pivotant 4a mobile, mais aussi de compenser la hauteur raccourcie du cadre rigide de panneau pivotant 4a et de le soutenir à bonne hauteur.  In this case, each inner casing 6a of wheel R comprises a raised rim 9 against rigid frame support of pivoting panel 4a. This flange 9 not only makes it possible to correctly maintain a rigid frame of pivoting panel 4a mobile, but also to compensate for the shortened height of the rigid frame of pivoting panel 4a and to support it at a good height.
