Abstract

The procedure consists of making a series of parallel folds (11,12,13,14,15) in the edge of the sheet (10), the last of which is formed by a perforated line (70). The free edge of the sheet is tucked inside the recessed edge (20) formed by the first and second folds to form a hollow rigid frame member.

Description

L'invention concerne les profilés raidisseurs de plaques de tôle mince.The invention relates to plate stiffening profiles of thin sheet metal.

Lorsque on réalise des objets en tôle mince, il est généralement nécessaire de raidir les plaques de tôle pour éviter leur déformation en les dotant, sur les côtés, d'éléments profilés constituant un cadre ou en déformant les bords de la plaque de tôle pour obtenir une section offrant un moment d'inertie transversal suffisant pour s'opposer à la déformation par flexion de ladite plaque de tôle.When making thin sheet metal objects, it is generally necessary to stiffen the sheet metal plates to avoid their deformation by endowing them, on the sides, of profiled elements constituting a frame or deforming the edges of the sheet metal plate to obtain a section offering a transverse moment of inertia sufficient to oppose bending deformation of said sheet metal plate.

On connaít déjà un procédé et un dispositif permettant d'obtenir directement, à partir d'une plaque de tôle mince, des tableaux métalliques à cadre de renfort intégré (brevet français n°2.469.896). La plaque de tôle est disposée sur une forme creuse de section appropriée munie, sur les côtés, d'une garniture d'étanchéité. Une dépression est alors appliquée dans l'espace délimité par le creux de la forme, afin de donner à ladite plaque une section correspondante à celle de la forme.We already know a method and a device for directly obtaining, from a thin sheet of metal, metal tables with integrated reinforcement frame (French Patent No. 2,469,896 ). The sheet metal plate is arranged on a hollow form of suitable section provided, on the sides, with a gasket. A vacuum is then applied in the space delimited by the hollow of the form, in order to give said plate a section corresponding to that of the form.

Un tel procédé et un tel dispositif si ils permettent de réduire au strict minimum le nombre des opérations de fabrication, présentent cependant l'inconvénient d'exiger une forme par dimension de tableau et de limiter le choix de la section du cadre à des sections ouvertes ; triangulaire, trapézoïdale ou rectangulaire qui doivent être ensuite comblées par une garniture ou fermées par l'intermédiaire d'une contre-plaque, séparée ou non par un panneau de bois. Such a method and such a device if they make it possible to reduce the number of operations to a minimum manufacturing, however have the disadvantage to require one form per table dimension and limit the choice of the section of the frame to sections open; triangular, trapezoidal or rectangular which must then be filled with a filling or closed by a separate backing plate or not by a wooden panel.

On connaít aussi, par la demande de brevet français n° 2.404.164, une bande métallique, à perforations multiples, se prêtant par pliage et contre-pliage à la réalisation de profilés de diverses sections, pouvant être ensuite coudés selon différents angles. Toutefois, ce système a été conçu uniquement pour permettre à des bricoleurs de réaliser à la demande, une gamme de profilés correspondants aux sections courantes et aux dimensions les plus courantes, ceci pour un prix de revient élevé excluant toute utilisation par l'industrie.Also known, from French patent application No. 2,404,164, a metal strip, with multiple perforations, suitable for folding and counter-folding to the production of profiles of various sections, which can then be bent at different angles. However, this system has been designed only to allow DIY enthusiasts to produce on demand, a range of profiles corresponding to common sections and the most common dimensions, this for a high cost price excluding any use by industry.

La présente invention a pour but de remédier à ces inconvénients. Cette invention, telle qu'elle est caractérisée dans les revendications, résout le problème consistant à définir un procédé et à créer un dispositif permettant la transformation directe des bords d'une tôle mince pour obtenir un profilé raidisseur utilisable en particulier pour constituer un cadre.The object of the present invention is to remedy these disadvantages. This invention, as it stands characterized in the claims, solves the problem of defining a process and creating a device allowing the direct transformation of the edges of a thin sheet to obtain a usable stiffening profile in particular to constitute a framework.

Les avantages obtenus grâce à cette invention consistent essentiellement en ceci que :

  • Le panneau de renfort est supprimé.
  • La tôle galvanisée de contre-collage est supprimée.
  • L'opération de collage des tôles contre les faces du panneau de renfort est supprimée.
  • La plaque renforcée ainsi obtenue est considérablement allégée par rapport au modèle traditionnel.
  • Les coûts de fabrication et de transport sont diminués dans des proportions importantes.
The advantages obtained thanks to this invention essentially consist in that:
  • The reinforcement panel is removed.
  • The galvanized sheet of laminating is removed.
  • The operation of gluing the sheets against the faces of the reinforcement panel is eliminated.
  • The reinforced plate thus obtained is considerably reduced compared to the traditional model.
  • The manufacturing and transport costs are significantly reduced.

Other characteristics and advantages will appear in the description below of the design and production of a dry erase board, intended for the general public, given by way of nonlimiting example with regard to the drawings in which:
  • FIG. 1 represents a partial perspective view of the table, with indication in dashed line of a step of intermediate formation of the profile.

Les figures représentent une tôle prélaquée 10 comportant sur au moins l'un de ses côtés, en allant vers le bord dudit côté, deux lignes de pliage très rapprochées 11 et 12 destinées à la réalisation d'un soyage 20, suivies de trois lignes de pliage parallèles espacées 13, 14 et 15, délimitant des bandes 30, 40, 50 et 60 constituant après pliage les côtés de la poutre 80 correspondante, dont l'une, 13, 14 ou 15 comporte des multiperforations 70 destinées à faciliter la réalisation manuelle du pli correspondant et de l'encliquetage du bord franc 16 de la bande d'extrémité 60 derrière le soyage 20 de la plaque 10. The figures represent a prepainted sheet 10 comprising on at least one of its sides, going towards the edge of said side, two very close fold lines 11 and 12 intended for carrying out a plunge 20 , followed by three lines of parallel folding spaced 13 , 14 and 15, delimiting strips 30, 40, 50 and 60 constituting after folding the sides of the corresponding beam 80 , one of which, 13, 14 or 15 comprises multi-perforations 70 intended to facilitate manual production of the corresponding fold and of the snap-fastening of the straight edge 16 of the end strip 60 behind the grooving 20 of the plate 10 .

En examinant maintenant plus en détail les figures 1 et 2, on remarque que, dans ce mode de réalisation, ainsi d'ailleurs que dans ceux qui seront exposés ci-après, la tôle 10 elle-même est utilisée comme flan pour obtenir une poutre latérale de renfort 80 intégrée, sans recourir au soudage ou au collage, par simple réalisation tout d'abord, de multiperforations 70 selon une ligne de pliage 15, puis pliage mécanique, selon les autres lignes, à l'aide par exemple d'une profileuse à galets, avant fermeture latérale de la poutre 80 par encliquetage derrière le soyage 20.Now examining Figures 1 and 2 in more detail , we note that, in this embodiment, as well as in those which will be explained below, the sheet 10 itself is used as a blank to obtain a beam lateral reinforcement 80 integrated, without resorting to welding or gluing, by first simply making multiperforations 70 along a fold line 15, then mechanical folding, along the other lines, using for example a roller profiling machine, before lateral closing of the beam 80 by snap-fastening behind the routing 20 .

En se rapportant aux figures 3 à 5 correspondant chacune à un mode de réalisation de la poutre de renfort 80, on remarque que, selon la ligne de pliage 13, 14 ou 15 qui est choisie pour réaliser les multiperforations 70, l'opération finale, permettant d'engager le bord 16 de la bande 60 derrière le soyage 20 consistera, pour les multiperforations 70 dans la ligne 15, à assurer le pliage d'angle alpha correspondant, selon cette ligne 15 (fig.3), pour la multiperforation 70 dans la ligne 14, à assurer un pliage à angle droit vers l'intérieur, salon la ligne 14 (fig.4) et pour les multiperforations 70, dans la ligne 13, à assurer aussi un pliage à angle droit vers l'intérieur, mais en suivant la ligne 13. La bande 60 ayant été, dans ces deux derniers modes de réalisation, pré-pliée selon un angle alpha adéquat.Referring to FIGS. 3 to 5 each corresponding to an embodiment of the reinforcing beam 80, it is noted that, according to the fold line 13, 14 or 15 which is chosen to carry out the multi-perforations 70, the final operation, allowing to engage the edge 16 of the strip 60 behind the plunge 20 will consist, for the multi-perforations 70 in the line 15, in ensuring the folding of corresponding alpha angle, according to this line 15 (fig. 3), for the multi-perforation 70 in line 14, to ensure a right-angled folding inwards, in line 14 (fig.4) and for multi-perforations 70, in line 13, to also ensure a right-angled folding inwards, but following line 13 . The strip 60 having been, in these last two embodiments, pre-folded at an adequate alpha angle.

En examinant maintenant la figure 6 correspondant à un mode de réalisation particulier de l'invention, la bande 60 est élargie et pré-pliée selon un angle béta, vers l'extérieur, préalablement au pliage final, selon le même angle béta que la bande 50 par rapport à la ligne 14 comportant les multiperforations 70, la largeur de ladite bande 50, ayant été déterminée de façon à obtenir le clipsage du pli 15 derrière le soyage 20. Now examining FIG. 6 corresponding to a particular embodiment of the invention, the strip 60 is widened and pre-folded at a beta angle, towards the outside, before the final folding, at the same beta angle as the strip 50 with respect to the line 14 comprising the multi-perforations 70, the width of the said strip 50, having been determined so as to obtain the clipping of the fold 15 behind the plunge 20.

Quel que soit le mode de réalisation, le clipsage du bord 16 de la bande 60 ou du pli réalisé selon la ligne 15 de la poutre 80 peut être obtenu manuellement ou mécaniquement par simple pliage au niveau de la ligne comportant les multiperforations 70 suivies d'une pression.Whatever the embodiment, the clipping of the edge 16 of the strip 60 or of the fold produced along line 15 of the beam 80 can be obtained manually or mechanically by simple folding at the level of the line comprising the multi-perforations 70 followed by a pressure.

Ainsi, le procédé de réalisation d'un tableau en tôle mince prélaquée comportant un cadre raidisseur intégré, selon l'invention, s'effectue en réalisant successivement les étapes ou opérations suivantes :

  • a) Découpage d'un flan de tôle comportant, sur les côtés, le développement des poutres d'encadrement et de renfort.
  • b) Réalisation des multiperforations 70 dans la ligne de pliage choisie 13, 14 ou 15.
  • c) Réalisation du pré-pliage, selon la version choisie.
  • d) Fermeture latérale de la poutre par pliage au niveau de la ligne comportant les multiperforations 70.
  • e) Encliquetage derrière le soyage 20 réalisé dans le flan à l'étape (C).
    • Thus, the process for producing a table made of pre-coated thin sheet metal comprising an integrated stiffening frame, according to the invention, is carried out by successively carrying out the following steps or operations:
  • a) Cutting a sheet blank comprising, on the sides, the development of the support and reinforcement beams.
  • b) Realization of multi-perforations 70 in the chosen fold line 13, 14 or 15 .
  • c) Carrying out pre-folding, depending on the version chosen.
  • d) Lateral closure of the beam by folding at the level of the line comprising the multi-perforations 70 .
  • e) Clicking behind the groove 20 made in the blank in step (C) .

    • Le dispositif et le procédé de renfort d'une tôle mince, selon l'invention, sont destinés principalement à la réalisation de tableaux tels que :

    • Tableau effaçable à sec.
    • Tableau d'affichage magnétique.
    • Grande ardoise.
    • Etc.
    The device and the method for reinforcing a thin sheet, according to the invention, are intended mainly for the production of panels such as:
    • Dry erase board.
    • Magnetic display board.
    • Large slate.
    • Etc.

    Toutefois, d'autres applications de l'invention sont envisageables, sous réserve d'adaptation évidente pour l'homme de métier, en particulier à partir de la version représentée à la figure 6.However, other applications of the invention are possible, subject to obvious adaptation for the person skilled in the art, in particular from the version shown in Figure 6.
