Abstract

Display frames involving use of angular polystyrene edging profiles supporting a back panel secured by solvent welding are assembled using a working platform shaped to centre the panel and the frame members respectively and to consolidate a solvent treated joint by compression from a cover plate. The cover plate has a soft (rubber) seal profile along its borders. Both the cover plate and the surface of the supporting platform, which is porous, can be evacuated to assist clamping and to remove superfluous solvent as vapour. Suitable for mfr. of single panel display boards or multi-panel free-standing poster display structures.

Description

La présente invention concerne le domaine de la fabrication de tableaux publicitaires, et a pour objet un procédé de fabrication d'un tableau avec cadre. The present invention relates to the field of manufacturing advertising boards, and relates to a method of manufacturing a board with frame.

l'invention a également pour objet un dispositif pour la mise en oeuvre de ce procédé, et le tableau ainsi obtenu. the invention also relates to a device for the implementation of this method, and the table thus obtained.

Actuellement, les tableaux publicitaires existants sont généralement constitues par un cadre en polystyrène, dans lequel est appliqué, au moyen de pinces, ou analogues, le support publicitaire avec interposition d'une plaque de carton et d'un poussoir en polystyrène expansé. Currently, existing advertising boards are generally constituted by a polystyrene frame, in which is applied, by means of pliers, or the like, the advertising medium with the interposition of a cardboard plate and an expanded polystyrene plunger.

Il existe également des tableaux, dont le cadre est constitué par des charnières auto-collantes assemblées avec le support. There are also tables, the frame of which consists of self-adhesive hinges assembled with the support.

Ces tableaux publicitaires, dont la durée d'utilisation est relativement réduite, sont cependant d'un prix de revient élevé, du fait qu'ils nécessitent un assemblage manuel relative ment long. En outre, de tels tableaux sont de constitution relativement fragile, et leur encombrement, notamment au stockage, est important. These advertising boards, whose duration of use is relatively short, are however of a high cost price, because they require a relatively long manual assembly. In addition, such tables are relatively fragile in constitution, and their size, especially during storage, is significant.

La présente invention a pour but de pallier ces inconvénients. The present invention aims to overcome these drawbacks.

Elle a, en effet, pour objet un procédé de fabrication d'un tableau avec cadre, caractérisé en ce qu'il consiste essentiellement à enduire un cadre profilé en polystyrène, sur le pourtour de sa face intérieure d'application du support, de solvant, à mettre le cadre en place sur le support, puis à appliquer le cadre sur ledit support sous l'effet d'une dépression s'exerçant de part et d'autre du support, de manière à réaliser une soudure des parties en présence, sous l'effet conjugué du solvant et de la pression, et enfin à munir le tableau obtenu d'une attache en polystyrène préalablement enduite d'un solvant sur sa face d'application. It has, in fact, for its object a process for manufacturing a table with a frame, characterized in that it essentially consists in coating a profiled frame in polystyrene, around the periphery of its inner face for application of the support, of solvent , to put the frame in place on the support, then to apply the frame to said support under the effect of a depression acting on either side of the support, so as to produce a welding of the parts present, under the combined effect of the solvent and the pressure, and finally to provide the table obtained with a fastener made of polystyrene previously coated with a solvent on its application face.

l'invention a également pour objet un dispositif pour la mise en oeuvre de ce procédé, caractérisé en ce qu'il est essentiellement constitué par une base d'application et de centrage du support, ainsi que de centrage du cadre, par un couvercle muni d'une bande d'application et d'étanchéité élastique ment déformable, et par un-ensemble de mise en dépression de la base et du couvercle. the invention also relates to a device for implementing this process, characterized in that it is essentially constituted by a base for application and centering of the support, as well as for centering the frame, by a cover provided an elastic and deformable application and sealing strip, and by a vacuum assembly of the base and the cover.

Le tableau avec cadre obtenu par mise en oeuvre du procédé conforme à l'invention dans le dispositif décrit ci-dessus est caractérisé en ce qu'il est constitué par un cadre profilé, dans lequel est fixé, contre sa face avant, le support, et dont la section de bord présente un angle obtus permettant un gerbage de plusieurs tableaux sur une faible hauteur. The table with frame obtained by implementing the method according to the invention in the device described above is characterized in that it is constituted by a profiled frame, in which is fixed, against its front face, the support, and the edge section of which has an obtuse angle allowing stacking of several tables over a small height.

l'invention sera mieux comprise grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence aux dessins schématiques annexés, dans lesquels la figure 1 est une vue en perspective du dispositif pour la mise en oeuvre du procédé conforme à l'invention, la figure 2 est une vue partielle en perspective et en coupe d'un tableau conforme à l'invention, et les figures 3 à 6 montrent schématiquement divers modes de présentation de tableaux conformes à l'invention. the invention will be better understood from the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawings, in which FIG. 1 is a view in perspective of the device for implementing the method according to the invention, FIG. 2 is a partial perspective view and in section of a table according to the invention, and FIGS. 3 to 6 schematically show various modes of presentation of tables according to the invention.

Comme le montre plus particulièrement, à titre d'exemple, la figure 1 des dessins annexés, le dispositif pour la mise en oeuvre du procédé conforme à l'invention est essentiellement constitué par une base 1 d'application et de centrage du support, par un couvercle 2 muni d'une bande 3 d'application et d'étanchéité élastiquement déformable, et par un ensemble 4 de mise en dépression de la base 1 et du couvercle 2. As shown more particularly, by way of example, FIG. 1 of the appended drawings, the device for implementing the method according to the invention essentially consists of a base 1 for applying and centering the support, by a cover 2 provided with an elastically deformable application and sealing strip 3, and by an assembly 4 for depressurizing the base 1 and the cover 2.

La base 1 se présente sous forme d'un plateau muni de multiples perforations, et pourvu à deux de ses coins de taquets 5 permettant un centrage du support. Cette base 1 est, en outre, munie de bords inclinés 6 permettant un centrage automatique du cadre, et ces bords sont raccordés à une boite à dépression 7 s'étendant sous toute la surface de la base 1. Cette boite de dépression 7 est raccordée à une turbine 8, par l'intermédiaire d'un conduit 9, et est munie d'un clapet 10 de mise à l'air libre commandé au moyen d'une tringlerie Il et d'une pédale 12, ou au moyen d'un levier, ou analogue. La boite 7 est, en outre, reliée par l'intermédiaire d'un conduit flexible 13 au couvercle 2 où elle débouche dans l'espace délimité par la bande d' étanchéité 3.Le couvercle 2 est relié au châssis de la base 1 au moyen de charnières 14, et sa bande d'étanchéité 3 est avantageusement
constituée en caoutchouc, ou en une autre matière à élasticité de caoutchouc. Pour garantir son maintien en position ouverte, le couvercle 2 est, en outre, pourvu à sa partie arrière d'un levier 15 actionné par un ressort 16 solidaire du châssis.The base 1 is in the form of a tray provided with multiple perforations, and provided with two of its wedges of lugs 5 allowing centering of the support. This base 1 is, moreover, provided with inclined edges 6 allowing automatic centering of the frame, and these edges are connected to a vacuum box 7 extending under the entire surface of the base 1. This vacuum box 7 is connected to a turbine 8, via a conduit 9, and is provided with a valve 10 for venting controlled by means of a linkage II and a pedal 12, or by means of a lever, or the like. The box 7 is, moreover, connected via a flexible conduit 13 to the cover 2 where it opens into the space delimited by the sealing strip 3. The cover 2 is connected to the chassis of the base 1 at hinge means 14, and its sealing strip 3 is advantageously
made of rubber, or other rubber elastic material. To guarantee that it remains in the open position, the cover 2 is further provided at its rear part with a lever 15 actuated by a spring 16 secured to the chassis.

Comme le montre la figure 2, l'invention a également pour objet un tableau avec cadre constitué par un cadre profilé 17, en polystyrène, par un support 18 fixé derrière le rebord 18 de la face avant du cadre 19, et par une attache de fixation murale non représentée. As shown in Figure 2, the invention also relates to a table with frame consisting of a profiled frame 17, made of polystyrene, by a support 18 fixed behind the flange 18 of the front face of the frame 19, and by a fastening wall mounting not shown.

La section de bord du cadre profilé 17 présente un angle obtus entre la face avant et le coté, de sorte que lors du stockage de plusieurs tableaux de même dimension, ceux-ci peuvent facilement etre empilés sur une faible hauteur. Cet angle est avantageusement de 120O, de sorte qu'il est possible d'assembler plusieurs tableaux par les bords de leur cadre, au moyen de pinces, ou analogues, pour former des diptyques ou des triptyques pouvant, par exemple, être exposés en vitrines. The edge section of the profiled frame 17 has an obtuse angle between the front face and the side, so that during the storage of several tables of the same dimension, these can easily be stacked on a low height. This angle is advantageously 120 °, so that it is possible to assemble several tables by the edges of their frame, by means of pliers, or the like, to form diptychs or triptychs which can, for example, be displayed in display cases. .

Ainsi, les figures 3 et 4 montrent deux modes d'assemblage de trois tableaux pour former des triptyques, et la figure 5 représente la réalisation dtun diptyque, ces divers modes dtas- semblage ne nécessitant aucun élément extérieur de stabilisation. Thus, FIGS. 3 and 4 show two modes of assembling three tables to form triptychs, and FIG. 5 represents the production of a diptych, these various modes of assembly requiring no external element of stabilization.

La figure 6 représente le montage d'un tableau sur un support carton connu en soi.Figure 6 shows the mounting of a table on a cardboard support known per se.

La fabrication d'un tableau conforme à l'invention s'effectue de la manière suivante
Un support est posé sur la base 1 et centré sur celle-ci au moyen des taquets 5, puis un cadre est enduit sur la partie intérieure de sa face avant d'un solvant, au moyen d'un tampon en feutre, et est mis en place sur la base 1 au-dessus du support, le centrage du cadre étant effectué grâce aux bords inclinés 6 de la base 1.La turbine 8, reliée à la boîte de dépression 7 de la base 1, par l'intermédiaire du conduit 9, est alors mise en marche, et le support est légèrement plaqué sur la base 1, puis le couvercle 2 est rabattu sur la base 1, de telle sorte qu'il appuie par sa bande d'étanchéité 3 sur le cadre, et la dépression, créée dans l'espace délimité par le couvercle 2 et la bande 3 au-dessus du support, grâce au conduit 12, a pour effet de serrer le -cadre sur le support, et de provoquer ainsi un soudage des parties en contact des deux éléments.Pour arrêter l'effet de serrage, l'opérateur appuie sur la pédale 12, afind'ouvrir le clapet 10 de mise à l'air libre, de sorte que la dépression dans le couvercle 2 et sous le support est supprimée, ledit couvercle 2 pouvant alors être soulevé sous l'action du ressort 16 sur le levier 15, et de sorte que le tableau définitif peut être retiré. le tableau ainsi réalisé peut alors encore être pourvu d'une attache fixée par pression sur la face arrière du support après enduction de la face d'application avec un solvant.The manufacture of a table according to the invention is carried out as follows
A support is placed on the base 1 and centered on it by means of the cleats 5, then a frame is coated on the inner part of its front face with a solvent, by means of a felt pad, and is put in place on the base 1 above the support, the centering of the frame being effected by means of the inclined edges 6 of the base 1. The turbine 8, connected to the vacuum box 7 of the base 1, via the conduit 9, is then started, and the support is slightly pressed on the base 1, then the cover 2 is folded down on the base 1, so that it presses by its sealing strip 3 on the frame, and the depression, created in the space delimited by the cover 2 and the strip 3 above the support, thanks to the conduit 12, has the effect of tightening the frame on the support, and thus causing a welding of the parts in contact with the To stop the clamping effect, the operator presses on the pedal 12, in order to open the air valve 10, so that the dep ression in the cover 2 and under the support is removed, said cover 2 can then be lifted under the action of the spring 16 on the lever 15, and so that the final table can be removed. the switchboard thus produced can then also be provided with a fastener fixed by pressure on the rear face of the support after coating the application face with a solvent.

Grâce à l'invention, il est possible de fabriquer des tableaux, en particulier des tableaux publicitaires, d'un faible pri#x de revient, et présentant un encombrement réduit lors du stockage, du fait qu'ils sont gerbables,
