Description

La présente invention concerne des bagages comportant une poignée rétractable rigide et aptes à être tractés sur des roulettes. L'invention se rapporte plus particulièrement à un sac à dos.The present invention relates to luggage comprising a retractable handle rigid and able to be towed on wheels. The invention relates more particularly to a backpack.

On connaít plusieurs types de sacs à dos munis de roulettes et d'une poignée rétractable. Ce genre de bagages à paroi en matériau souple s'est avéré particulièrement pratique et connaít ces dernières années un succès grandissant. Ces bagages sont constitués d'un sac adapté à un système de roulage prévu pour des valises, ce qui conduit à un sac relativement lourd et encombrant.We know several types of backpacks equipped with casters and a retractable handle. This kind of baggage with flexible material wall proved particularly practical and known in recent years a growing success. These baggage consists of a bag adapted to a rolling system provided for suitcases, which leads to a relatively heavy and bulky bag.

On connaít en effet déjà des valises ou sacs à dos à roulettes dérivant des valises roulantes du type "trolley". Il s'agit en fait d'utiliser un système télescopique de valise de cabine (dit "trolley") sur lequel un sac à dos a été adapté. Ainsi, les sacs à dos à roulettes de l'art antérieur comportent une poignée rétractable, généralement formée par deux tubes coulissants, le long de la face "arrière" c'est à dire celle qui est destinée à être en contact avec le dos de l'utilisateur. Cette disposition présente un désavantage du point de vue du comfort, le système télescopique de la poignée étant rigide. Un important rembourrage supplémentaire est nécessaire pour éviter le contact direct du dos avec cet élément longitudinal dur. We already know cases or backpacks to casters deriving from rolling suitcases of the type "trolley". It's actually about using a system telescopic cabin suitcase (called "trolley") on which a backpack has been adapted. So the backpacks to castors of the prior art have a handle retractable, usually formed by two tubes sliding, along the "back" side ie one that is intended to be in contact with the back of the user. This provision presents a disadvantage from the point of view of comfort, the telescopic system of the handle being rigid. Important padding extra is needed to avoid contact direct back with this hard longitudinal element.

De plus le système de roulage, prévu à l'origine pour être monté sur une valise, est lourd, encombrant et disproportionné. Le sac à dos est monté à la place prévue pour la valise. Les roulettes sont extérieures et situées à la base de ladite face arrière et sont ainsi, lorsque le bagage est utilisé comme un sac à dos, de nature à salir les vêtements au dos de l'utilisateur étant donné que ces roulettes ont été en contact avec le trottoir et des détritus, et éventuellement même avec des déjections de chiens. La présence d'un rabat apte à envelopper les roulettes ne constitue qu'un pis-aller car pour reprendre l'utilisation des roulettes, la face du rabat éventuellement souillée est exposée et peut être en contact avec l'utilisateur.In addition the rolling system, originally intended to be mounted on a suitcase, is heavy, bulky and disproportionate. The backpack is mounted in the place provided for the suitcase. The casters are exterior and located at the base of said rear face and so, when the luggage is used as a backpack, so dirty the clothes on the back of the user since these casters were in contact with the sidewalk and detritus, and possibly even with dogs. The presence of a flap able to envelop the casters is only a second-best the use of the casters, the flap face possibly soiled is exposed and may be in contact with the user.

L'art antérieur est illustré par de nombreux documents. Plus spécifiquement et à titre d'exemple, le document de brevet US 5.743.363 décrit notamment un bagage à roulettes et à poignée télescopique constituant un sac à dos et comprenant une plaque de rigidification. Les roulettes sont localisées sur une face latérale et adjacente à la face recevant le système télescopique.The prior art is illustrated by numerous documents. More specifically and by way of example, the US Patent 5,743,363 describes in particular a wheeled luggage and telescopic handle constituting a backpack and comprising a stiffening plate. The wheels are located on a side face and adjacent to the face receiving the telescopic system.

Le document de brevet US 5.676.286 divulgue un sac à dos munies de roulettes sur une plaque solidarisée à la face inférieure du sac. Les roulettes sont opposées au côté en contact avec le dos.US 5,676,286 discloses a backpack equipped with wheels on a plate secured to the face bottom of the bag. The rollers are opposite the side in contact with the back.

Le document de brevet GB 2.300.117 décrit une structure réglable destinée à être reçue dans divers sacs de voyage. On y décrit une plaque supérieure de soutien du matériau souple de bagage fixée au bagage de l'extérieur. GB Patent 2,300,117 describes a structure adjustable to be received in various travel bags. There is described a top plate for supporting the material flexible baggage attached to luggage from the outside.

On recherche cependant toujours une augmentation de l'aspect pratique et du comfort d'utilisation de ces bagages roulants, en particulier des sacs à dos, tout en assurant une diminution du poids sans entraver la solidité.However, an increase of the convenience and comfort of using these luggage, especially backpacks, while ensuring a reduction in weight without hindering the solidity.

La présente invention vise à remédier aux inconvénients susmentionnés et à améliorer les qualités de comfort d'utilisation et de légèreté. Le sac à dos n'est plus adapté à un système de roulage, ce dernier étant au contraire adapté à la forme et à l'utilisation du sac à dos.The present invention aims at remedying the disadvantages mentioned above and to improve the comfort qualities of use and lightness. The backpack is no longer adapted to a rolling system, the latter being contrary to the shape and use of the back.

Dans ce but l'invention propose un sac à dos tel que défini dans la revendication 1 annexée. Ce sac à dos présente des parois en matériau souple, par exemple en tissu, comportant une poignée rétractable par coulissement de son manche, et une plaque intérieure de fond incurvée, l'incurvation de cette plaque semi-rigide étant imposée par la solidarisation de cette plaque, p.e. par rivetage, à un segment de profil incurvé s'étendant à partir de la base du logement télescopique, intérieur au bagage, de la poignée coulissante. La plaque semi rigide peut être une plaque en plastique, par exemple en polyéthylène avec une épaisseur variant de 1 à 5 mm.For this purpose the invention proposes a bag for back as defined in appended claim 1. This backpack has walls of flexible material, for example fabric, having a retractable handle by sliding of its handle, and a curved bottom interior plate, the curvature of this semi-rigid plate being imposed by securing this plate, eg by riveting, to a curved profile segment extending from the base of the telescopic housing, interior to the luggage, the sliding handle. The semi-rigid plate can be a plastic plate, for example polyethylene with a thickness ranging from 1 to 5 mm.

Les parois du bagage en matériau souple seront de préférence prévues pour former un bagage de forme approximativement parallélipipédique rectangle.The walls of the luggage made of flexible material will be preferably provided to form a form luggage approximately parallelepiped rectangle.

Au lieu d'une poignée à une tige, on peut également prévoir une poignée en U télescopique, comportant deux tiges coulissant dans deux logements parallèles. Chaque logement est solidarisé à la plaque incurvée inférieure et à la plaque supérieure comme pour le bagage à une seule tige.Instead of a handle with a stem, you can also provide a telescopic U-shaped handle with two sliding rods in two parallel housing. Each housing is secured to the lower curved plate and to the top plate as for single luggage rod.

Selon une variante, la plaque de fond peut être une plaque moulée plus rigide, par exemple en ABS ou polypropylène, dont l'incurvation est formée d'origine. Dans ce cas, la base du logement télescopique ne doit pas nécessairement être incurvée et/ou aplatie et peut être droite si on prévoit un moyen de fixation solide et rigide sur la partie relevée de la plaque de fond (p.e. bride).Alternatively, the bottom plate may be a plate molded more rigid, for example ABS or polypropylene, whose curvature is originally formed. In this case telescopic housing base does not necessarily have to to be curved and / or flattened and can be straight if one provides for a solid and rigid fastening means on the raised part of the bottom plate (eg flange).

Dans le cas d'une plaque semi-rigide, l'incurvation est également obtenue, en particulier au niveau de ses parties latérales, par deux éléments en arceaux de support d'axe de roues latérales faisant saillie hors de la partie incurvée de ladite plaque. In the case of a semi-rigid plate, the curvature is also obtained, in particular at the level of its parts lateral, by two elements in support arches of axis side wheels projecting out of the game curved of said plate.

Le système de poignée télescopique est prévu adjacent et intérieur à la face opposée à celle qui est destinée à être en contact avec le dos, c'est à dire à celle pourvue de sangles pour l'utilisation comme sac à dos. Le comfort en est ainsi grandement amélioré.The telescopic handle system is provided adjacent and inside on the opposite side to the one intended for to be in contact with the back, ie to that provided of straps for use as a backpack. Comfort this is greatly improved.

Avantageusement, le bord de la plaque inférieure opposé à la base du logement télescopique présente un profil horizontal courbé concave. Ce profil, en contact avec le dos, épouse davantage le profil transversal du dos et augmente ainsi le confort de l'utilisateur et/ou évite une usure prématurée d'un coussin de protection prévu sur la face en contact avec le dos.Advantageously, the edge of the lower plate opposite to the base of the telescopic housing presents a profile horizontal curved concave. This profile, in contact with the back, further marries the transverse profile of the back and thus increases the comfort of the user and / or avoids a premature wear of a protective cushion provided on the face in contact with the back.

En outre on peut prévoir un bourrelet s'adaptant à la tranche présentée par ledit bord, par exemple sous la forme d'un manchon de mousse fendu longitudinalement.In addition, it is possible to provide a bead that adapts to the slice presented by said edge, for example under the shape of a foam sleeve split longitudinally.

Le manche de la poignée rétractable peut être constitué d'un tube creux de section carrée, rectangulaire ou polygonale, par exemple en aluminium, mais peut aussi constituer une poignée en U, auquel cas la section peut être ronde. Le manche sera cependant avantageusement, surtout pour les bagages de petites dimensions, constitué d'un tube télescopique simple ou double coulissant de manière connue dans un logement rigide prévu à cet effet.The handle of the retractable handle can be constituted hollow tube of square, rectangular or polygonal, for example aluminum, but can also U-shaped handle, in which case the section may to be round. The handle will however advantageously, especially for small luggage, made up of a single or double sliding telescopic tube known manner in a rigid housing provided for this purpose.

Selon un aspect important de l'invention on prévoit également une plaque de soutien du matériau souple (p.e. tissu), de préférence mais pas obligatoirement de même nature que la plaque de fond incurvée, agencée à l'extrémité supérieure du logement de la poignée télescopique, perpendiculairement à ce logement. Cette plaque est maintenue par un moyen de fixation, p.e. une noix de serrage prévue à cet effet sur le logement. La dimension de cette plaque peut varier, de telle manière que, selon un mode de réalisation préféré, seule une partie du matériau souple, entourant l'extrémité supérieure du logement peut être retenue. En particulier, cette plaque de soutien ne s'étendra de préférence pas sur toute la profondeur de la valise.According to an important aspect of the invention, also a support plate of the flexible material (e.g. tissue), preferably but not necessarily the same nature that the curved bottom plate, arranged at the upper end of the handle housing telescopic, perpendicular to this housing. This plate is held by a fastening means, p.e. clamping nut provided for this purpose on the housing. The dimension of this plate may vary, in such a way that, according to a preferred embodiment, only one part of the flexible material, surrounding the end upper housing can be retained. In particular, this support plate will not extend from preferably not on the entire depth of the bag.

La face supérieure peut alors comprendre une plaque auxiliaire indépendante, ne servant qu'à une meilleure fixation d'une poignée de type classique. En effet, de manière classique, en plus de la poignée télescopique, des poignées supplémentaires peuvent être prévues cousues et/ou rivetées sur une ou plusieurs des faces.The upper face can then include a plate independent auxiliary, serving only for a better fixing a conventional type handle. Indeed, classical way, in addition to the telescopic handle, additional handles can be planned stitched and / or riveted on one or more faces.

La rigidité verticale du sac à dos en matériau souple est assurée essentiellement par le système de roulage, la plaque incurvée et le système télescopique. L'invention propose donc des bagages dont la structure rigide est essentiellement en L, ou en forme de cornière, dans la mesure ou la plaque supérieure transversale est de surface relativement réduite, ce qui favorise l'empilabilité étant donné que les faces latérales et , en partie, la face supérieure peuvent être repliées vers l'intérieur.The vertical stiffness of the backpack made of soft material is essentially ensured by the rolling system, the curved plate and telescopic system. The invention therefore proposes luggage whose rigid structure is essentially L-shaped, or angle-shaped, in the measure or the upper cross plate is from relatively small area, which favors stackability since the side faces and, in part, the upper side can be folded towards inside.

Selon un mode de réalisation, le moyen d'ouverture du sac à dos décrit ci-dessus sera une ouverture à glissière s'étendant de la face supérieure, sur les faces latérales, de part et d'autre, de manière telle qu'une fois le sac ouvert, la partie du matériau souple supportée par la plaque supérieure est séparée de la partie du matériau souple non supportée.According to one embodiment, the means for opening the bag backpack described above will be a zipper opening extending from the upper face, on the lateral faces, on both sides, so that once the bag open, the part of the flexible material supported by the upper plate is separated from the part of the material flexible unsupported.

Selon une variante, une des faces comporte le long de trois côtés de son périmètre une fermeture à glissière permettant le rabattement de cette face.According to one variant, one of the faces comprises along three sides of its perimeter a zipper allowing the folding of this face.

La face ou partie de face rabattable peut comprendre une ou plusieurs poches et/ou un ou plusieurs compartiments auxiliaires.The flip-up face or portion may include a or several pockets and / or one or more compartments Auxiliary.

Dans le cas de sacs à dos de plus grandes dimensions, on peut avantageusement prévoir un renfort vertical s'étendant sur une partie de la face adjacente au système télescopique de poignée, solidarisé à la plaque supérieure par fixation à un équerre. Selon une variante on peut prévoir un élément en cornière intégré. Un équerre n'est alors plus nécessaireIn the case of larger backpacks, can advantageously provide a vertical reinforcement extending over part of the face adjacent to the system telescopic handle, secured to the top plate by fixing to a square. According to a variant one can provide an integrated angle element. A square is not then no longer necessary

Selon un autre mode de réalisation de l'invention, on prévoit en outre un jonc métallique en U renversé parcourant le bord supérieur et les deux bords latéraux de la face adjacente au système télescopique. Ce jonc est avantageusement intégré dans un passepoil souple dont les extrémités dépassent les branches du U et sont incurvées pour former ainsi les deux bords inférieurs latéraux. According to another embodiment of the invention, also provides an inverted U-shaped metal ring traversing the upper edge and the two lateral edges of the face adjacent to the telescopic system. This ring is advantageously integrated in a flexible piping whose ends protrude from the branches of the U and are curved to thus form the two lower lateral edges.

Il est bien entendu que les parois intérieures des compartiments des bagages selon l'invention peuvent être avantageusement doublées avec une garniture en tissu, cachant la plaque de fond et le logement télescopique.It is understood that the interior walls of luggage compartments according to the invention may be advantageously doubled with a cloth lining, hiding the bottom plate and the telescopic housing.

L'invention sera mieux comprise à l'examen des dessins soumis en annexe, uniquement à titre d'exemple, dans lesquels

  • la figure 1 représente un schéma de la structure interne d'un sac à dos selon l'invention
  • la figure 2 représente en perspective une vue "avant" d'un sac à dos complet selon l'invention
  • la figure 3 représente une vue "arrière" d'un sac à dos selon l'invention,
  • la figure 4 représente une variante du sac à dos comportant une poignée en U
  • les figures 5a et 5b illustrent un détail de réalisation de l'invention consistant en un jonc de rigidification de la face adjacente au système télescopique.
The invention will be better understood on examining the drawings submitted in the appendix, solely by way of example, in which
  • FIG. 1 represents a diagram of the internal structure of a backpack according to the invention.
  • FIG. 2 represents in perspective a "front" view of a complete backpack according to the invention

  • FIG. 4 shows a variant of the backpack comprising a U-shaped handle
  • Figures 5a and 5b illustrate a detail of the invention consisting of a reinforcing ring of the side adjacent to the telescopic system.

Dans les différentes figures, les numéros de référence identiques se rapportent à des éléments identiques ou fonctionnellement équivalents.In the different figures, the reference numbers identical refer to identical elements or functionally equivalent.

La fig. 1 représente schématiquement en perspective une vue partiellement éclatée de la structure rigide d'un sac à dos selon l'invention. On reconnaít une tige ou un manche 1 et un logement métallique 10 dans lequel coulisse le tube ou manche 1 doublement télescopique de section carrée ou rectangulaire, de préférence en aluminium. La partie inférieure 11 du logement s'étend sous la forme d'un segment incurvé auquel est solidarisé par rivetage une plaque de fond 2 semi-rigide par exemple en polyéthylène. Cette partie incurvée prolongeant le logement télescopique peut être avantageusement aplatie, et peut résulter en fait de l'aplatissement d'une extrémité d'un profilé creux à section carrée ou rectangulaire. La plaque de fond 2 comprend deux ouvertures 8 pour accueillir des roulettes prévues sur des éléments en arceaux 5, à solidariser de l'extérieur par rivetage à la plaque 2. Ces arceaux contribuent ainsi à l'incurvation homogène sur toute sa largeur. On illustre également des pieds 6 du côté opposées aux roulettes. Fig. 1 schematically represents in perspective a partially exploded view of the rigid structure of a bag backpack according to the invention. We recognize a stem or a sleeve 1 and a metal housing 10 in which slides the tube or sleeve 1 doubly telescopic section square or rectangular, preferably aluminum. The lower part 11 of the housing extends in the form a curved segment to which is secured by riveting a semi-rigid bottom plate 2 for example in polyethylene. This curved part extending the housing telescopic can be advantageously flattened, and can result in fact from the flattening of one end of a hollow profile with square or rectangular section. The bottom plate 2 includes two openings 8 for accommodate casters provided on elements in hoops 5, to be secured from the outside by riveting to the plate 2. These arches thus contribute to the curvature homogeneous over its entire width. We also illustrate feet 6 on the opposite side to the rollers.

On notera que le profil de la tranche 12 de la plaque peut également être incurvé pour mieux épouser le profil du dos, lorsque la valise est utilisée comme sac à dos. La tranche étant en outre couverte d'un manchon de protection 14 fendu longitudinalement.Note that the profile of the slice 12 of the plate can also be curved to better fit the profile of the back, when the suitcase is used as a backpack. The slice being additionally covered with a protective sleeve 14 split longitudinally.

Une plaque de soutien 3 de même nature que la plaque de fond est prévue à la partie supérieure du logement 10, fermement maintenue par un moyen de fixation, par exemple une noix de serrage 4. De préférence cette plaque de soutien ne s'étendra pas sur toute l'épaisseur de la valise afin d'éviter un contact avec la partie supérieure du dos ou avec le cou de l'utilisateur. On illustre également un renfort vertical 15, également sous la forme d'une plaque, solidarisée à la plaque de soutien supérieure 3 par fixation à une équerre 9 intermédiaire.A support plate 3 of the same nature as the plate of bottom is provided at the top of housing 10, firmly held by a fastening means, for example a clamping nut 4. Preferably this plate of support will not extend over the full thickness of the suitcase to avoid contact with the upper from the back or with the user's neck. We illustrate also a vertical reinforcement 15, also in the form a plate, secured to the support plate upper 3 by fixing to an intermediate square 9.

La figure 2 est une vue en perspective du sac à dos vu du côté de la paroi adjacente à la poignée rétractable. Le mécanisme télescopique est interne au sac à dos. On distingue un compartiment avant 21 et la tirette 23 d'ouverture qui s'étend sur deux faces latérales et la face supérieure et permet en rabattant la paroi arrière d'avoir accès au compartiment principal 24. A la base de trois faces verticales, le matériau souple est doublé d'un second matériau 25 de préférence en plastique, par exemple en PVC grainé, rendant la base des faces latérales 26 moins souple, en diminuant l'usure, et permettant avantageusement un nettoyage plus aisé. Les arceaux des roulettes 28 sont situés aux coins inférieurs de la face comportant le système télescopique et comportent un rebord incurvé 29 de protection du passepoil 22, épousant le bord incurvé de la plaque de fond. La plaque de support intérieure non montrée s'étend jusqu'à la tirette 23 et sert également de support à la poignée classique 30.FIG. 2 is a perspective view of the backpack as seen from side of the wall adjacent to the retractable handle. The Telescopic mechanism is internal to the backpack. We distinguishes a front compartment 21 and the zipper 23 opening which extends on two lateral faces and the upper side and allows by folding the rear wall to have access to the main compartment 24. At the base of three vertical faces, the flexible material is doubled with a second material 25 preferably plastic, for example in grained PVC, making the base of the lateral faces 26 less flexible, reducing wear, and allowing advantageously easier cleaning. The hoops roulettes 28 are located at the lower corners of the face having the telescopic system and having a rim curved 29 of piping protection 22, marrying the edge curved bottom plate. The support plate interior not shown extends to the zipper 23 and also serves as a support for the classic handle 30.

La figure 3 est une représentation d'un sac à dos similaire à celui de la figure 2 vue du côté opposé à la paroi adjacente à la poignée rétractable. On distingue les sangles 31 qui peuvent être partiellement détachées au niveau des boucles d'attache 32 et introduites dans une poche 33 prévue à cet effet. De plus un coussin 34 est prévu pour protéger davantage encore la partie inférieure du dos de l'utilisateur. La poignée 30 est fixée sur la partie rabattable avec la face opposée à celle adjacente au système télescopique, le matériau souple adjacent à cette poignée étant intérieurement renforcé par une petite plaque non illustrée.Figure 3 is a representation of a backpack similar to that of Figure 2 seen from the opposite side to the wall adjacent to the retractable handle. We distinguish straps 31 which can be partially detached to the level of the attachment loops 32 and introduced into a pocket 33 provided for this purpose. In addition a cushion 34 is planned to further protect the lower part from the back of the user. The handle 30 is fixed on the foldable part with the opposite side to the adjacent one the telescopic system, the flexible material adjacent to this handle being internally reinforced by a small plate not illustrated.

La figure 4 représente une variante du sac à dos tel que représenté dans les figures 2 et 3, plus adaptée pour un bagage de grandes dimensions. La poignée télescopique 7 comprend en effet deux tiges doublement télescopiques 1,1'. De plus, cette poignée 7 peut se rétracter jusqu'à l'intérieur du sac et être recouverte par un rabat 40 avec fermeture à glissière. FIG. 4 shows a variant of the backpack as shown in Figures 2 and 3, more suitable for a large luggage. The telescopic handle 7 includes two double telescopic rods 1.1. In addition, this handle 7 can retract up to inside the bag and be covered by a flap 40 with zipper.

On peut prévoir un passepoil 22 qui comprend un élément métallique 50 formant jonc de rigidification, illustré à la figure 5a, en U renversé parcourant trois bords de la face adjacente au système télescopique. Ce jonc 50 est avantageusement intégré dans un passepoil souple (22) dont les extrémités dépassent les branches du U et sont incurvées à l'intérieur de l'arceau 5, protégé par le rebord 29 pour former ainsi les deux arêtes inférieures latérales.We can provide a piping 22 which comprises a metal element 50 forming a stiffening ring, illustrated in FIG. 5a, inverted U traversing three edges of the face adjacent to the telescopic system. This ring 50 is advantageously integrated in a flexible piping (22) whose ends protrude from the branches of the U and are curved inside the hoop 5, protected by the rim 29 for thus form the two lower lateral edges.

La figure 5b est un agrandissement du profil en perspective du passepoil 22 dans lequel l'élément 50 s'insère au montage.Figure 5b is a enlargement of the perspective profile of the piping 22 in which the element 50 is inserted in the assembly.
