Abstract

Luggage of the type including means enabling it to be displaced by being rolled over the ground, characterised in that it is composed of a closed central compartment of general cylindrical shape, with a horizontal axis, and of a rolling strip concentric with this compartment, means being provided between the said compartment and the said strip to enable them to pivot freely with respect to each other, a grip (handle) being fastened on the outside of the said compartment so that the user, pulling on this handle, moves the luggage assembly by rolling the rolling strip over the ground.

Description

La présente invention concerne une nouvelle structure de bagage à main, se prêtant facilement à un transport et une manipulation quels que soient son poids et sa dimension. The present invention relates to a new structure of hand luggage, easily suitable for transport and handling regardless of its weight and size.

II est bien connu que les procédures d'enregistrement et de récupération des bagages, -notamment dans les aéroports, obligent les voyageurs à manipuler eux mêmes leurs bagages, le personnel (les porteurs de gares) étant inexistant et les chariots malcommodes ou mal adaptés. It is well known that the procedures for checking in and recovering luggage, especially at airports, require travelers to handle their luggage themselves, the staff (the porters of stations) being non-existent and the carts uncomfortable or ill-suited.

Pour pallier cet inconvénient on a proposé de nombreuses valises et bagages munis de roulettes et éventuellement de poignées et(ou de timons servant à les tirer derrière soi en les faisant rouler sur le sol. L'expérience montre que l'usage de ces artifices était toujours malcommode, la raison principale étant que lesdites roulettes sont de petites dimensions et nécessairement placées à la partie inférieure du bagage, qui se déplace inévitablement de manière instable. To overcome this drawback, numerous suitcases and luggage have been proposed fitted with rollers and possibly with handles and (or drawbars used to pull them behind by rolling them on the ground. Experience shows that the use of these devices was always inconvenient, the main reason being that said rollers are small and necessarily placed at the bottom of the luggage, which inevitably moves unstably.

L'invention vise donc une structure nouvelle grâce à laquelle il est possible de déplacer un bagage sans effort et sans risque d'instabilité, même quand il est lourd et encombrant. The invention therefore aims at a new structure thanks to which it is possible to move baggage effortlessly and without risk of instability, even when it is heavy and bulky.

A cet effet, cette nouvelle structure se compose d'un compartiment constituant luimême le bagage, de forme générale cylindrique à axe horizontal, et d'une bande de roulement sensiblement concentrique à ce compartiment et munie de moyens lui permettant de pivoter librement par rapport à ce compartiment, une poignée étant fixée extérieurement audit compartiment, de manière telle que l'usager, exerçant une traction sur ladite poignée, déplace ledit compartiment en faisant rouler sur le sol la bande de roulement à l'intérieur de laquelle demeure ledit compartiment sensiblement immobile en rotation. To this end, this new structure consists of a compartment itself constituting the baggage, of generally cylindrical shape with horizontal axis, and a tread substantially concentric with this compartment and provided with means allowing it to pivot freely relative to this compartment, a handle being fixed externally to said compartment, so that the user, exerting traction on said handle, moves said compartment by rolling the tread on the ground inside which remains said substantially stationary compartment in rotation.

Selon une réalisation de l'invention, le compartiment intérieur étant cylindrique, la poignée constitue une fourche dont les deux branches sont fixées aux extrémités de l'axe dudit cylindre, la bande de roulement ayant une section en forme de U dont les deux branches latérales se logent dans des rainures correspondantes de la surface latérale dudit cylindre, des moyens étant prévus pour permettre la rotation relative dudit cylindre et de ladite bande. According to one embodiment of the invention, the interior compartment being cylindrical, the handle constitutes a fork, the two branches of which are fixed to the ends of the axis of said cylinder, the tread having a U-shaped section of which the two lateral branches are housed in corresponding grooves of the lateral surface of said cylinder, means being provided to allow the relative rotation of said cylinder and said strip.

Selon une autre caractéristique de l'invention, le couvercle du compartiment intérieur constitue un disque solidaire d'une des branches de ladite fourche, montée basculante à cet effet. According to another characteristic of the invention, the cover of the interior compartment constitutes a disc integral with one of the branches of said fork, mounted tiltably for this purpose.

Selon une autre caractéristique encore, ledit couvercle est monté pivotant sur la face latérale correspondante dudit compartiment, I'obturation dudit compartiment se faisant par vissage dudit couvercle. According to yet another characteristic, said cover is pivotally mounted on the corresponding side face of said compartment, the closure of said compartment being made by screwing said cover.

L'invention va être maintenant exposée plus en détail grâce à la description ciaprès d'un mode de réalisation illustré par le dessin annexé sur lequel
La figure 1 est une vue latérale d'une valise selon l'invention, et la figure 2 est une coupe diamétrale de la même valise.The invention will now be explained in more detail thanks to the following description of an embodiment illustrated by the appended drawing in which
Figure 1 is a side view of a suitcase according to the invention, and Figure 2 is a diametrical section of the same suitcase.

Selon l'invention, la valise se compose d'un compartiment intérieur cylindrique 1, considéré comme fixe, autour duquel est disposé pivotante une bande de roulement 2, I'ensemble étant destiné à être manipulé par une poignée 3 montée sur une fourche 4-4' fixée aux extrémités de l'axe XX' du cylindre 1. According to the invention, the bag consists of a cylindrical interior compartment 1, considered to be fixed, around which a tread 2 is pivotally disposed, the assembly being intended to be manipulated by a handle 3 mounted on a fork 4- 4 'fixed to the ends of the axis XX' of the cylinder 1.

Le compartiment 1, destiné à être rempli d'un contenu quelconque, est fermé par un couvercle 5 pouvant être manipulé par basculement de la fourche 4' autour d'un pivot 6, comme indiqué en trait interrompu. The compartment 1, intended to be filled with any content, is closed by a cover 5 which can be manipulated by tilting the fork 4 'around a pivot 6, as indicated in broken lines.

La bande de roulement entoure le compartiment 1 avec interposition de moyens lui permettant de tourner par rapport à lui, tels que billes, galets ou analogues, désignés par la référence générale 7. The tread surrounds compartment 1 with the interposition of means allowing it to rotate relative to it, such as balls, rollers or the like, designated by the general reference 7.

Elle est adaptée autour du compartiment 1 par exemple par enroulement et serrage par tout moyen approprié, de préférence démontable, et immobilisée contre tout déplacement latéral par coopération entre des nervures 8 et des rainures 9. It is adapted around compartment 1, for example by winding and tightening by any suitable means, preferably removable, and immobilized against any lateral displacement by cooperation between ribs 8 and grooves 9.

L'utilisation de ce bagage est simple. Une fois l'intérieur du compartiment 1 rempli, on referme le couvercle 5, et on l'immobilise par exemple par vissage, par rotation autour d'un axe 10. The use of this baggage is simple. Once the interior of the compartment 1 is filled, the cover 5 is closed, and it is immobilized for example by screwing, by rotation about an axis 10.

On retourne alors le bagage, en le faisant reposer sur le sol et par la bande de roulement 2. Il suffit alors de le tirer par la poignée 3, la bande 2 roulant sur le sol S tandis que le compartiment 1 demeure immobile en rotation. Grâce au grand diamètre de roulement, il est facile de manipuler le bagage quels que soient les obstacles et les inégalités de terrain telles que les trottoirs. The luggage is then turned over, making it rest on the ground and by the tread 2. It then suffices to pull it by the handle 3, the band 2 rolling on the ground S while the compartment 1 remains stationary in rotation. Thanks to the large rolling diameter, it is easy to handle the luggage regardless of obstacles and uneven terrain such as sidewalks.

II est évident que l'on pourrait imaginer une forme simplifiée de ce bagage, dans laquelle c'est le compartiment 1 qui roule directement sur le sol, rendant superflue la bande 2. It is obvious that one could imagine a simplified form of this baggage, in which it is the compartment 1 which rolls directly on the ground, making the strip 2 superfluous.

Toutefois, I'expérience montre qu'à l'usage une tel bagage simplifié présente de nombreux inconvénients dont le moindre n'est pas le désordre créé dans le contenu du compartiment 1, soumis à un véritable mélangeage par sa rotation. However, experience has shown that in use such a simplified baggage has many drawbacks, the least of which is not the disorder created in the contents of compartment 1, which is subjected to real mixing by its rotation.

C'est pour écarter cet inconvénient que le bagage selon l'invention comporte la bande de roulement rotative 2 et le compartiment 1 qui doit demeurer immobile. It is to overcome this drawback that the luggage according to the invention comprises the rotating tread 2 and the compartment 1 which must remain stationary.

Pour assurer cette immobilité, non seulement les moyens 7 doivent permettre la rotation relative à la bande 2 par rapport au compartiment 1, mais au surplus, il est préférable que les extrémités 11 des branches 4 et 4' de la fourche soient fixées à l'axe XX' de manière soit à immobiliser cet axe, soit à empêcher le compartiment 1 de tourner sur cet axe. To ensure this immobility, not only the means 7 must allow rotation relative to the strip 2 relative to the compartment 1, but moreover, it is preferable that the ends 11 of the legs 4 and 4 'of the fork are fixed to the axis XX 'so as either to immobilize this axis, or to prevent compartment 1 from rotating on this axis.
