Abstract

Rigid shells for the bodies of suitcases etc. are made from a combination of a double-walled thermoplastic sheet profile linked by parallel bridges and a bonded cover of decorative material, sufficiently pliant to follow subsequent thermoforming of the thermoplastic support. Pref. the double-wall profile is extruded from ABS, polypropylene or polycarbonate. The decorative cover should be much less stiff when hot than when cold, pref. is a felt or a non-woven fabric opt. supported on an intermediate lining of flexible polyether or polyurethane foam. The component layers may be prefabricated and subsequently stuck together as flat sheets or may be continuously laminated at the extrusion stage. Used to obtain a higher stiffness/wt. ratio than for bodies made of solid sheet matls. and to avoid stitching or patching techniques for securing the cover materials.

Description

La présente invention concerne des coques de valises ou autres bagages, ainsi que leur procédé de fabrication. The present invention relates to shells of suitcases or other baggage, as well as their manufacturing process.

Actuellement les bagages rigides (valises, malettes, coffrets ou autres) sont fabriques à partir de coques pleines obtenues par formage ou injection de matières plastiques, érentuellement revêtues ensuite d'un habillage. Currently rigid luggage (suitcases, briefcases, boxes or others) are made from full shells obtained by forming or injection of plastics, erentually then coated with a covering.

Les bagages ainsi obtenus, s'ils présentent des qualités de solidité et de rigidité incontestables, sont toutefois lourds et cet inconvénient leur est souvent reproche. C'est ainsi qu'une coque de valise de 50 x 40 cm et d'une profondeur de 6 cm pèse environ 700 g. The baggage thus obtained, if it exhibits indisputable solidity and rigidity qualities, is however heavy and this drawback is often criticized. Thus a suitcase shell of 50 x 40 cm and a depth of 6 cm weighs about 700 g.

De plus, le revêtement de l'une ou des deux faces d'une couche dthabillage est une opération coûteuse du point de vue main dwoeuvre. Enfin, la finition de la ou des couches d'habillage fait apparaître des découpes et reprises apparentes dues à la forme non développable de la coque de valise. In addition, coating one or both sides with a covering layer is an expensive operation from a labor point of view. Finally, the finish of the covering layer (s) reveals visible cut-outs and overlaps due to the non-developable shape of the suitcase shell.

La présente invention s'est donnée pour but de remédier à ces inconvénients en proposant de nouvelles coques pour bagages rigides qui allient à une parfaite rigidité une légèreté non atteinte jusqu'alors, un aspect impeccable en raison de la qualité de l'habillage sans couture ni reprise et qui peut être obtenue de façon économique en raison d'une diminution certaine du coût de main d'oeuvre de l'habillage. The purpose of the present invention is to remedy these drawbacks by proposing new shells for rigid luggage which combine perfect rigidity with lightness not previously achieved, an impeccable appearance due to the quality of the seamless covering. nor recovery and which can be obtained economically due to a certain reduction in the labor cost of the covering.

C'est ainsi que l'invention a pour objet des coques pour valises et autres bagages rigides dont l'originalité consiste en ce qu'elles sont constituées d'une feuille de matière plastique à double paroi régulièrement entretoisée associée, sur au moins l'une de ses faces, à une couche d'habillage. Thus the invention relates to shells for suitcases and other rigid luggage whose originality consists in that they consist of a sheet of double-walled plastic material regularly braced associated, on at least the one of its faces, with a covering layer.

La résine synthétique constituant la feuille de matitre plastique à double paroi est avantageusement choisie parmi les résines thermoplastiques telles que les résines acrylonitrile-butadiène-styrène, polypropylène ou polycarbonate.  The synthetic resin constituting the double-walled plastic master sheet is advantageously chosen from thermoplastic resins such as acrylonitrile-butadiene-styrene, polypropylene or polycarbonate resins.

Selon un mode de réalisation préféré de l'invention, la couche d'habillage présente à chaud une résistance à la déformation très inférieure à celle qu'elle présente à froid. According to a preferred embodiment of the invention, the covering layer exhibits, when hot, a resistance to deformation much lower than that which it exhibits when cold.

Le choix de cette couche d'habillage permet de résoudre le problème spécifique posé par le thermoformage sous vide d'une coque habillée sur ses deux faces. The choice of this covering layer makes it possible to solve the specific problem posed by thermoforming under vacuum of a shell coated on its two faces.

En effet, l'habillage s'il est correctement posé sur la plaque et que l'on a résolu le problème de barrière de température qu'il occasionne, travaille en arrachement et arrive par la seule force nécessaire à sa de for- mation à désolidáriser les deux parois plastiques en arrachant les entretoises. In fact, the covering, if it is correctly placed on the plate and the problem of temperature barrier that it causes has been resolved, works in tearing and arrives by the only force necessary for its formation to detach the two plastic walls by tearing off the spacers.

Un habillage présentait à chaud une résistance à la déformation très inférieure a calle obtenue à froid, permet d'éviter l'arrachement en conservant un produit correctement lié à froid, c'est-à-dire dont la fibre ne fond pas au frottement. A covering exhibited, when hot, a resistance to deformation much lower than calle obtained when cold, makes it possible to avoid tearing by keeping a product properly bonded to cold, that is to say the fiber of which does not melt under friction.

La couche d'habillage est de préférence un feutre ou non tissé dont les fibres sont liées par voie physique, physicochimique ou chimique, et est éventuellement doublée d'une couche de mousse synthétique en polyéther ou polyu éthane.  The covering layer is preferably a felt or nonwoven, the fibers of which are linked physically, physicochemically or chemically, and is optionally lined with a layer of synthetic polyether or polyurethane foam.

La présente invention sera mieux comprise à l'aide de la description qui suit d'un mode de fabrication de la coque formée selon l'invention, en référence au dessin schématique annexé dans# lequel
Figure i est une vue en coupe schématique d'un mode de réalisation du complexe avant l'opération de formage
Figure 2 est une vue schématique en coupe d'une partie de la coque selon figure 1, après formage.The present invention will be better understood on the basis of the following description of a method of manufacturing the shell formed according to the invention, with reference to the appended schematic drawing in which #
Figure i is a schematic sectional view of an embodiment of the complex before the forming operation
Figure 2 is a schematic sectional view of part of the shell according to Figure 1, after forming.

Comme on le voit sur les figures, la coque selon l'invention est essentiellement constituée d'une feuille de matière plastique a double paroi régulièrement entretoi séb 3 , associée sur une de ses faces à une couche d'habillage i.  As can be seen in the figures, the shell according to the invention essentially consists of a sheet of double-walled plastic material regularly maintained between seb 3, associated on one of its faces with a covering layer i.

Le schéma de fabrication (non représenté) du complexe selon l'invention est le suivant
La feuille de matière plastique à double paroi ré gulierement entretoisée 3, obtenue par extrusion d'une résine thermoplastique telle qu'une résine acrylonitrile dutadiène-styrène, une résine polypropylène ou une résine polycarbonate est, à la sortie de l'extrudeuse, associée par collage ou autre à la couche d'habillage 4.Cette couche peut être constituée de tout feutre ou non tissé de type connu en soi, obtenu à partir de fibres de toute origine liées entre elles par voie physique, physico-chimique ou chimique, et est éventuellement contrecollée à une couche de mousse plastique telle qu'une couche de mousse de polyéther ou de polyurethane (non représentée). Le collage de la feuille de matière plastique 3 et de la couche d'habillage 4 est effectué par tout procédé connu en soi qu'il s'agisse de thermocollage effectué directement à la sortie de l'extrudeuse ou de collage par apport d'un adhésif convenable, éventuellement suivi d'une opération de séchage et/ou de polymérisation.The manufacturing scheme (not shown) of the complex according to the invention is as follows
The regularly braced double-walled plastic sheet 3 obtained by extruding a thermoplastic resin such as an acrylonitrile dutadiene-styrene resin, a polypropylene resin or a polycarbonate resin is, at the outlet of the extruder, associated by bonding or other to the covering layer 4.This layer can consist of any felt or nonwoven of the type known per se, obtained from fibers of any origin linked together by physical, physico-chemical or chemical means, and is optionally laminated with a layer of plastic foam such as a layer of polyether or polyurethane foam (not shown). The bonding of the plastic sheet 3 and the covering layer 4 is carried out by any process known per se, whether it is heat-bonding carried out directly at the outlet of the extruder or bonding by adding a suitable adhesive, possibly followed by a drying and / or polymerization operation.

Le complexe 2 ainsi obtenu est ensuite soumis à une opération classique de thermoformage sous vide au cours de laquelle il acquiert sa forme définitive telle que, par exemple, celle représentéé à la figure 2. The complex 2 thus obtained is then subjected to a conventional vacuum thermoforming operation during which it acquires its final shape such as, for example, that shown in FIG. 2.

Comme on le voit sur cette figure, l'ôpaisseur de la coque 2 reste constante sur toute la surface, même aux points d'inflexion du galbe communiqué au cours de cette opération de formage sous vide. As can be seen in this figure, the thickness of the shell 2 remains constant over the entire surface, even at the points of inflection of the curve communicated during this vacuum forming operation.

Il est bien évident que, selon le même processus, les deux faces de la feuille 3 pourraient être revêtues d'une couche d'habillage telle que i.  It is obvious that, according to the same process, the two faces of the sheet 3 could be coated with a covering layer such as i.

Le procédé de fabrication qui vient d'être décrit permet de réaliser des économies importantes en main d'oeuvre pour l'opération d'habillage ; on dispose ainsi de coques alliant à une parfaite rigidité une légèreté non atteinte jusqu'alors et ne présentant ni couture, ni reprise sur leur face habillée. The manufacturing process which has just been described makes it possible to achieve significant savings in labor for the dressing operation; shells are thus available which combine perfect rigidity with a lightness not previously attained and presenting neither stitching nor recovery on their dressed face.

Comme il va de soi et comme il ressort de ce qui précède, la présente invention ne se limite pas à la seule réalisation ci-dessus décrite à titre d'exemple non limitatif ; elle en embrasse, au contraire, toutes les variantes de réalisation, quelles que soient notamment la nature et l'épaisseur relative des constituants de la coque, ainsi que la forme communiquée à ladite coque.  As is obvious and as appears from the above, the present invention is not limited to the single embodiment described above by way of nonlimiting example; on the contrary, it embraces all the variant embodiments thereof, whatever in particular the nature and the relative thickness of the constituents of the shell, as well as the shape communicated to said shell.
