Description

SYSTEME D'ASSEMBLAGE DE COMPOSANTS EN MOUSSE PLASTIQUE EXPANSÉE. SYSTEM FOR ASSEMBLING EXPANDED PLASTIC FOAM COMPONENTS.
La présente invention concerne un système modulaire formé de panneaux raccordables. Les applications concernent en particulier la réalisation de mobiliers modulaires pour enfants .The present invention relates to a modular system formed of connectable panels. The applications relate in particular to the production of modular furniture for children.
On connaît dans l'état de la technique des éléments de construction modulaire en mousse présentant des moyens d'accrochage en queue d'aronde. De tels éléments sont décrit dans le brevet américain US5212842. Les possibilités offertes par de tels panneaux sont toutefois limitées, et la robustesse des assemblages est limitée.There are known in the prior art modular foam construction elements having dovetail hooking means. Such elements are described in American patent US5212842. The possibilities offered by such panels are however limited, and the robustness of the assemblies is limited.
Un autre exemple de réalisation d'un système modulaire a été décrit dans le brevet américain US1894061. Il s'agit également d'un système dans lequel l'interconnexion est réalisée par des encastrements complémentaires. Les mêmes problèmes de modularité restreinte et de solidité se posent. Le but de la présente invention est de remédier à ces inconvénients en proposant un système robuste, permettant une grande variété de réalisations.Another exemplary embodiment of a modular system has been described in American patent US1894061. It is also a system in which the interconnection is achieved by complementary embedding. The same problems of restricted modularity and solidity arise. The object of the present invention is to remedy these drawbacks by proposing a robust system, allowing a wide variety of embodiments.
A cet effet, l'invention concerne selon son acception la plus générale un système modulaire composé d'une pluralité de panneaux présentant chacun des encastrements, certains panneaux au moins présentant des encastrements femelles formés par des perforations et certains panneaux au moins présentant dans la zone périphérique des tenons mâles complémentaires caractérisé en ce que les panneaux sont des panneaux de mousse expansée présentant dans la zone centrale un réseau bidimensionnel de perforations de section cylindrique fermée et en ce que les tenons s ' encastrement de force dans lesdites perforations cylindriques. On entend par cylindrique au sens de la présente demande de brevet toute forme engendrée par le déplacement d'une ligne selon un schéma continu. Une perforation cylindrique englobe donc des perforations à section carrée, triangulaire, rectangulaire, ronde, ovale etc.. . Avantageusement, les tenons forment des protubérances latérales formées sur les tranches des panneau .To this end, the invention relates in its most general sense to a modular system composed of a plurality of panels each having recesses, at least some panels having female recesses formed by perforations and at least some panels having in the area peripheral of the complementary male studs characterized in that the panels are panels of expanded foam having in the central area a two-dimensional network of perforations of closed cylindrical section and in that the studs are forcibly embedded in said cylindrical perforations. For the purposes of the present patent application, the term “cylindrical” means any shape generated by the displacement of a line in a continuous pattern. A cylindrical perforation therefore includes perforations with square, triangular, rectangular, round, oval, etc. sections. Advantageously, the studs form lateral protuberances formed on the edges of the panels.
Selon une variante préférée, les tenons présentent une section transversale carrée. Avantageusement, les perforations forment des rangées alignées avec les axes médians d'une paire de tenons disposées respectivement sur deux bords opposés.According to a preferred variant, the posts have a square cross section. Advantageously, the perforations form rows aligned with the median axes of a pair of studs disposed respectively on two opposite edges.
Selon un mode de réalisation préféré, les tenons présentent une section légèrement supérieure à la section des perforations.According to a preferred embodiment, the studs have a section slightly greater than the section of the perforations.
Selon une variante, les perforations présentent des faces internes légèrement concaves .According to a variant, the perforations have slightly concave internal faces.
Selon une autre variante, les perforations présentent des faces internes légèrement convexes . De préférence, les panneaux sont des panneaux multiplis .According to another variant, the perforations have slightly convex internal faces. Preferably, the panels are plywood panels.
L'invention concerne également un équipement pour la découpe de perforations présentant des faces internes non planes dans un panneau caractérisé en ce qu'il comporte des couteaux et une matrice complémentaire forme par une plaque (10) montée sur ressort assurant la compression du panneau au moment de la coupe.The invention also relates to equipment for cutting perforations having non-planar internal faces in a panel characterized in that it comprises knives and a complementary matrix by a plate (10) mounted on a spring ensuring the compression of the panel at the time of cutting.
La présente invention sera mieux comprise à la lecture de la description d'un exemple non limitatif de réalisation qui suit, ce référant aux dessins annexés où : la figure 1 représente une vue en perspective d'un assemblage de panneaux selon l'invention ; la figure 2 représente une vue en coupe transversale d'un panneau selonThe present invention will be better understood on reading the description of a nonlimiting exemplary embodiment which follows, referring to the appended drawings where: FIG. 1 represents a perspective view of an assembly of panels according to the invention; Figure 2 shows a cross-sectional view of a panel according to
1 ' invention ; les figures 3 et 4 représentent deux vue en coupe d'un équipement de découpe.The invention; Figures 3 and 4 show two sectional views of cutting equipment.
La figure 1 représente l'assemblage de deux panneaux (5, 6) selon l'invention. Les panneaux sont des panneaux en mousse expansée d'une épaisseur comprise entreFigure 1 shows the assembly of two panels (5, 6) according to the invention. The panels are expanded foam panels with a thickness between
5 et 100 millimètres. Il peut en particulier s'agir de panneaux multiplis formés par la superposition de plusieurs couches, par exemple 5 couches, de feuilles de mousse expansée assemblées par collage.5 and 100 millimeters. It can in particular be multi-ply panels formed by the superposition of several layers, for example 5 layers, of expanded foam sheets assembled by gluing.
Les panneaux sont découpés à la presse en une ou plusieurs passes au moyen de couteaux, suivant une trame régulière (2) de perforations (3). Ces perforations peuvent être de section carrée, circulaire, rectangulaire, triangulaire, etc. Dans l'exemple décrit, les perforations (3) sont de section carrée, et présentent une largeur légèrement inférieure à l'épaisseur du panneau, afin d'assurer un blocage ferme par déformation élastique de la partie venant s'encastrer dans la perforation. La périphérie du panneau est découpée pour former des tenons (4) à section carrée, et de forme générale cubique. Ces tenons (4) sont régulièrement espacés d'une distance correspondant à l'épaisseur du panneau. La tranche des panneaux présente un crénelage avec une alternance de tenons (4) et de découpes rentrantes de volumes identiques .The panels are cut in the press in one or more passes by means of knives, following a regular weft (2) of perforations (3). These perforations can be square, circular, rectangular, triangular, etc. In the example described, the perforations (3) are of square section, and have a width slightly less than the thickness of the panel, in order to ensure firm blocking by elastic deformation of the part which is embedded in the perforation. The periphery of the panel is cut to form tenons (4) with a square section, and of generally cubic shape. These tenons (4) are regularly spaced by a distance corresponding to the thickness of the panel. The edge of the panels has aliasing with alternating tenons (4) and re-entrant cutouts of identical volumes.
L'assemblage de deux panneaux se fait par emboîtement des tenons (4) d'un panneau dans les découpes (3) d'un autre panneau. La surface de frottement développée par les emboîtements garantit la résistance de l'assemblage grâce à l'expansion de la mousse après découpe.The assembly of two panels is done by fitting the tenons (4) of one panel into the cutouts (3) of another panel. The friction surface developed by the sockets guarantees the resistance of the assembly thanks to the expansion of the foam after cutting.
Pour améliorer cette résistance, il est proposé de procéder à une découpe des perforations comme représenté en figure 2. Les flancs des découpes sont convexes (partie droite de la figure) , la découpe présentant un volume en forme de diabolo, ou concaves (partie gauche de la figure) , la découpe présentant alors un volume en forme de tonneau. Lorsque le panneau est un panneau multiplis, les flancs des découpes sont crénelés.To improve this resistance, it is proposed to cut the perforations as shown in Figure 2. The sides of the cuts are convex (right part of the figure), the cut having a volume in the form of a diabolo, or concave (left part in the figure), the cut-out then having a barrel-shaped volume. When the panel is a plywood panel, the sides of the cutouts are crenellated.
Ces formes en « diabolo » ou en « tonneau » permettent d'améliorer l'ancrage et le verrouillage de deux panneaux assemblés.These “diabolo” or “barrel” shapes make it possible to improve the anchoring and locking of two assembled panels.
Le procédé consiste à assembler les différents composants par emboîtement des parties mâles dans les perforations ou redans. La surface de frottement développée par un nombre adéquat d'emboîtements garantit la résistance de l'assemblage désirée grâce à l'expansion de la mousse après découpe. Cette expansion s'inscrit selon une forme particulière optimisant les frottements donc la résistance de l'encastrement.The method consists in assembling the different components by fitting the male parts into the perforations or steps. The friction surface developed by an adequate number of sockets guarantees the resistance of the desired assembly thanks to the expansion of the foam after cutting. This expansion takes place in a form particular optimizing friction therefore the resistance of embedding.
Pour y atteindre, un procédé de découpe à la presse au moyen de couteaux (7) détermine un profil particulier dans l'épaisseur de la mousse : les parties femelles ou perforations (3) comportent des faces internes légèrement concaves ou légèrement convexes de telle façon que les parties mâles ou tenons (4) affectant à contrario des faces extérieures légèrement convexes ou concaves s'encastrent à force en déterminant un verrouillage rendant l'arrachement de l'assemblage difficile (Fig. 3).To achieve this, a press cutting process using knives (7) determines a particular profile in the thickness of the foam: the female parts or perforations (3) have slightly concave or slightly convex internal faces so that the male parts or tenons (4) affecting, on the contrary, slightly convex or concave outer faces are forced into place by determining a locking making the tearing of the assembly difficult (Fig. 3).
Les tenons (4) peuvent être d'une section légèrement supérieure à celle des perforations (3) afin d'augmenter la pression exercée par l'expansion de la mousse après découpe.The studs (4) can be of a section slightly greater than that of the perforations (3) in order to increase the pressure exerted by the expansion of the foam after cutting.
Le profil des tenons (4) et des perforations (3) est traité de façon aléatoire en fondant l'essentiel des frottements sur la section supérieure des tenons par rapport à celle des perforations. A la fabrication des pièces dans la presseThe profile of the studs (4) and of the perforations (3) is treated randomly by basing most of the friction on the upper section of the studs relative to that of the perforations. In the production of parts in the press
(12), on utilise des couteaux selon le profil (7 ou 8) selon qu'il s'agit de provoquer un profil concave ou convexe, complétés d'un dispositif (9) comprenant une plaque (10) montée sur ressort (11) de rappel qui comprime la mousse (1) au moment de la coupe et permet de déterminer le profil courbe (Fig. 3 et 4) . Au montage, on introduit perpendiculairement et à force la pièce (5) comportant les redans dans celle comportant les découpes (6). Quand l'emboîtement est engagé à fond, on obtient un encastrement satisfaisant grâce à la pression exercée sur les redans (4) par l'expansion des parois des perforations (3).(12), knives are used according to the profile (7 or 8) depending on whether it is a question of causing a concave or convex profile, supplemented by a device (9) comprising a plate (10) mounted on a spring (11 ) reminder which compresses the foam (1) at the time of cutting and makes it possible to determine the curved profile (Fig. 3 and 4). During assembly, the part (5) comprising the steps is inserted perpendicularly and by force into that comprising the cutouts (6). When the fitting is fully engaged, we get a fitting satisfactory thanks to the pressure exerted on the steps (4) by the expansion of the walls of the perforations (3).
Une variante de réalisation consiste à découper d'abord une pluralité de feuilles de mousse expansée en découpant en particulier des perforations (3) présentant des flancs non plans. Ces feuilles sont assemblées après découpe par collage pour réaliser un panneau multiplis. Les déformations des perforations superposées conduisent à des flancs intérieurs La présente invention trouve son application naturelle dans le domaine du mobilier.An alternative embodiment consists in first cutting a plurality of sheets of expanded foam by cutting in particular perforations (3) having non-planar sides. These sheets are assembled after cutting by gluing to make a plywood panel. The deformations of the superimposed perforations lead to internal sides. The present invention finds its natural application in the field of furniture.
En effet, elle se prête à une fabrication industrielle en série des composants avec une faible main d ' œuvre . Le contenu des perforations en forme de cubes étant conservé à sa place, il n'y a pas manutention et la pièce est réputée finie et propre au conditionnement dès la sortie de la presse. A partir d'un nombre limité de composants partageant la même trame, il est possible de développer un large nombre de combinaisons enrichies esthétiquement d'une possibilité d'association de panneaux- formats de coloris variés . Indeed, it lends itself to industrial mass production of components with a low labor force. The content of the cube-shaped perforations being kept in its place, there is no handling and the part is deemed finished and suitable for packaging as soon as it leaves the press. From a limited number of components sharing the same frame, it is possible to develop a large number of aesthetically enriched combinations with the possibility of combining panels - formats of various colors.
