Description

Le brevet principal a pour objet un procédé de mise en place d'un médaillon rapporté sur un panneau, ou analogue, préformé, qui consiste essentiellement à introduire la périphérie du médaillon dans une gorge de faible section, de forme correspondante à celle du pourtour dudit médaillon, et à fixer ladite périphérie dans le fond de ladite gorge par soudage thermique, par induction, ou autre, de manière à obtenir un joint de soudage invisible entre le médaillon et le panneau. The main patent relates to a method of placing a medallion attached to a panel, or the like, preformed, which essentially consists in introducing the periphery of the medallion into a groove of small section, of shape corresponding to that of the circumference of said medallion, and to fix said periphery in the bottom of said groove by thermal, induction, or other welding, so as to obtain an invisible welding joint between the medallion and the panel.

Le brevet principal a également pour objet un panneau, ou analogue, préformé, muni d'un médaillon relié, à sa périphérie, au panneau, par un joint de soudage invisible disposé au fond d'une gorge de faible section de forme correspondante à celle du pourtour du médaillon. The main patent also relates to a panel, or the like, preformed, provided with a medallion connected, at its periphery, to the panel, by an invisible welding joint disposed at the bottom of a groove of small cross section of shape corresponding to that around the medallion.

La présente demande de certificat d'addition a pour objet des variantes de réalisation de ce procédé. The present request for addition certificate relates to alternative embodiments of this process.

Conformément à l'invention, le procédé consiste essentiellement à centrer le médaillon formé par un ensemble tissu à pourcentage d'allongement important et mousse, le périmètre de cette dernière étant situé en retrait par rapport à celui du tissu, sur le panneau de support, à appuyer ce complexe dans le fond d'une gorge concentrique intérieurement au pourtour du médaillon, dans la zone comportant la mousse, au moyen d'un poinçon, puis à presser et à souder les bords du tissu formant le médaillon dans le fond d'une gorge périphérique extérieure du panneau au moyen d'un poinçon de soudage. According to the invention, the method essentially consists in centering the medallion formed by a fabric assembly with a large percentage of elongation and foam, the perimeter of the latter being set back relative to that of the fabric, on the support panel, to press this complex in the bottom of a concentric groove internally around the medallion, in the zone comprising the foam, by means of a punch, then to press and weld the edges of the fabric forming the medallion in the bottom of an outer peripheral groove of the panel by means of a welding punch.

La valeur du retrait de la mousse par rapport au tissu est variable en fonction de la surface du médaillon et du volume de ce dernier.  The value of the shrinkage of the foam relative to the fabric is variable depending on the surface of the medallion and the volume of the latter.

Selon une variante de réalisation de l'invention, l'opération finale de pressage et de soudage des bords du tissu dans la gorge périphérique extérieure est effectuée en deux phases, respectivement au moyen d'un poinçon de pressage du tissu au fond de la gorge, puis au moyen d'un poinçon de soudage. According to an alternative embodiment of the invention, the final operation of pressing and welding the edges of the fabric in the outer peripheral groove is carried out in two phases, respectively by means of a punch for pressing the tissue at the bottom of the groove , then by means of a welding punch.

L'invention a également pour objet un panneau, ou analogue, préformé, muni d'un médaillon, caractérisé en ce que le médaillon est relié, par la périphérie du tissu le constituant et dépassant la périphérie de la mousse, au panneau pourvu de deux gorges concentriques, dont la gorge extérieure correspond au pourtour de la mousse constituant le médaillon, par un joint de soudage invisible disposé au fond de la gorge de plus grand développement. The invention also relates to a panel, or the like, preformed, provided with a medallion, characterized in that the medallion is connected, by the periphery of the fabric constituting it and projecting beyond the periphery of the foam, to the panel provided with two concentric grooves, the outer groove of which corresponds to the periphery of the foam constituting the medallion, by an invisible welding joint placed at the bottom of the groove of greatest development.

Enfin, l'invention a pour objet un dispositif pour la mise en oeuvre du procédé décrit ci-dessus caractérisé en ce qu'il est essentiellement constitué par un poinçon de formage et de soudage comportant un élément de centrage du complexe tissu et mousse formant le médaillon monté à déplacement, contre l'action de ressorts, sur des axes de guidage verticaux et sur lequel s'emboite la matrice de réception du panneau à munir du médaillon, par au moins un poinçon de pressage du complexe ou du tissu à pourcentage d'allongement important dans l'une des gorges concentriques du panneau, monté concentriquement dans l'élément de centrage avec possibilité de déplacement, contre l'action de ressorts, en direction d'une plaque de support servant simultanément au montage des axes de guidage de l'élément de centrage du complexe, et par un poin çon de soudage disposé concentriquement entre le ou les poinçons de pressage et l'élément de centrage et monté de manière fixe sur la plaque de support. Finally, the subject of the invention is a device for implementing the method described above, characterized in that it is essentially constituted by a punch for forming and welding comprising an element for centering the fabric and foam complex forming the medallion mounted to move, against the action of springs, on vertical guide pins and on which fits the receiving matrix of the panel to be provided with the medallion, by at least one punch for pressing the complex or percentage tissue significant elongation in one of the concentric grooves of the panel, mounted concentrically in the centering element with the possibility of displacement, against the action of springs, in the direction of a support plate serving simultaneously for mounting the guide axes of the centering element of the complex, and by a welding punch arranged concentrically between the pressing punch (s) and the centering element and fixedly mounted on the support plate.

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
les figures la à ld sont des vues partielles en élévation latérale et en coupe des diverses phases de réalisation du procédé conforme à l'invention ;

la figure 3 est une vue en élévation latérale et en coupe, à plus grande échelle, du dispositif pour la mise en oeuvre du procédé.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
Figures la to ld are partial views in side elevation and in section of the various stages of carrying out the process according to the invention;
FIG. 2 is a partial view in side elevation and in section of a panel provided with a medallion according to the invention, and
Figure 3 is a side elevational view in section, on a larger scale, of the device for carrying out the method.

Conformément à l'inventionr et comme le montrent plus particulièrement, à titre d'exemple, les figures la à lc des dessins annexés, le procédé de mise en place d'un médaillon 1 rapporté sur un panneau 2, ou analogue, préformé, consiste essentiellement à centrer le médaillon 1 constitué par un ensemble tissu à pourcentage d'allongement important et mousse, le périmètre de cette dernière étant situé en retrait par rapport à celui du tissu, sur le panneau de support 2, à appuyer ce complexe dans le fond d'une gorge 6 concentrique intérieurement au pourtour du médaillon 1, dans la zone comportant la mousse, au moyen d'un poinçon 7, puis à presser et à souder les bords du tissu formant le médaillon 1 dans le fond d'une gorge périphérique extérieure 8 du panneau 2 au moyen d'un poin çon de soudage 9.Ainsi, il est possible de réaliser un centrage parfait du médaillon 1 sur le panneau 2 au moyen du poinçon 7, le poinçon de soudage 9 réalisant simultanément l'introduction et le soudage des bords du tissu au fond de la gorge périphérique extérieure 8. In accordance with the invention and as shown more particularly, by way of example, FIGS. 1a to 1c of the appended drawings, the method of fitting a medallion 1 attached to a panel 2, or the like, preformed, consists essentially to center the medallion 1 consisting of a fabric assembly with a large percentage of elongation and foam, the perimeter of the latter being set back relative to that of the fabric, on the support panel 2, to support this complex at the bottom a groove 6 concentrically inside the periphery of the medallion 1, in the zone comprising the foam, by means of a punch 7, then pressing and welding the edges of the fabric forming the medallion 1 in the bottom of a peripheral groove outside 8 of the panel 2 by means of a welding punch 9. Thus, it is possible to achieve perfect centering of the medallion 1 on the panel 2 by means of the punch 7, the welding punch 9 performing simultaneously t the introduction and welding of the edges of the fabric at the bottom of the outer peripheral groove 8.

Selon une autre caractéristique de l'invention, l'opération finale de pressage et de soudage des bords du tissu dans la gorge périphérique extérieure est effectuée en deux phases, respectivement au moyen d'un poinçon de pressage 10 du tissu au fond de ladite gorge périphérique extérieure 8, puis au moyen d'un poinçon de soudage 11 (figure ld). Dans ce mode de réalisation du procédé, le poinçon de soudage 9 suivant le premier procédé (figure lc) est remplacé par un deuxième poinçon de pressage 10 et le soudage du bord du tissu dans la gorge extérieure 8 n'est réalisé, avec le poinçon 11, qu'après application du bord dudit tissu au fond de ladite gorge 8. According to another characteristic of the invention, the final operation of pressing and welding the edges of the fabric in the outer peripheral groove is carried out in two phases, respectively by means of a punch 10 for pressing the fabric at the bottom of said groove external device 8, then by means of a welding punch 11 (FIG. ld). In this embodiment of the method, the welding punch 9 according to the first method (FIG. 1c) is replaced by a second pressing punch 10 and the welding of the edge of the fabric in the external groove 8 is not carried out, with the punch 11, only after application of the edge of said fabric to the bottom of said groove 8.

Ce mode de réalisation permet d'améliorer encore le centrage du médaillon 1 sur le panneau 2 et d'améliorer la précision de l'insertion des bords du tissu dans la gorge extérieure 8. This embodiment makes it possible to further improve the centering of the medallion 1 on the panel 2 and to improve the precision of the insertion of the edges of the fabric in the external groove 8.

L'invention a également pour objet un dispositif pour la mise en oeuvre du procédé décrit ci-dessus, qui est essentiellement constitué par un poinçon de formage et de soudage comportant un élément 12 de centrage du complexe tissu et mousse formant le médaillon 1 monté à déplacement, contre l'action de ressorts 13, sur des axes de guidage verticaux 14. Sur cet élément 12 s'emboite la matrice 15 de réception du panneau 2 à munir du médaillon 1. Le dispositif comporte, en outre, au moins un poinçon 7 de pressage du complexe ou du tissu à pourcentage d'allongement important dans l'une, 6, des gorges concentriques du panneau 2, monté concentriquement dans l'élément de centrage 12 avec possibilité de déplacement, contre l'action de ressorts 16, en direction d'une plaque de support 17 servant simultanément au montage des axes 14 de guidage de l'élément de centrage 12 du complexe. The invention also relates to a device for implementing the method described above, which essentially consists of a forming and welding punch comprising an element 12 for centering the tissue and foam complex forming the medallion 1 mounted at displacement, against the action of springs 13, on vertical guide pins 14. On this element 12 fits the matrix 15 for receiving the panel 2 to be provided with the medallion 1. The device further comprises at least one punch 7 for pressing the complex or the fabric with a large percentage of elongation in one, 6, of the concentric grooves of the panel 2, mounted concentrically in the centering element 12 with the possibility of displacement, against the action of springs 16, towards a support plate 17 serving simultaneously for mounting the axes 14 for guiding the centering element 12 of the complex.

Enfin, un poinçon de soudage 18 est disposé concentriquement entre le poinçon de pressage 7 et l'élément de centrage 12 et est monté de manière fixe sur la plaque de support 17. Finally, a welding punch 18 is arranged concentrically between the pressing punch 7 and the centering element 12 and is fixedly mounted on the support plate 17.

Dans la constitution décrite ci-dessus le dispositif permet la mise en oeuvre du procédé selon le premier mode de réalisation, à savoir permet de réaliser un pressage du complexe tissu et mousse au moyen du poinçon 7 dans la gorge intérieure 6 et le soudage au moyen du poin çon 18 qui correspond, dans ce mode de réalisation, au poinçon 9 de la figure lc. In the constitution described above the device allows the implementation of the method according to the first embodiment, namely allows to carry out a pressing of the tissue and foam complex by means of the punch 7 in the inner groove 6 and the welding by means of the punch 18 which corresponds, in this embodiment, to the punch 9 of FIG.

Conformément à une autre caractéristique de l'invention, le dispositif est avantageusement pourvu de deux poinçons de pressage concentriques, à savoir un poinçon 7 intérieur et un poinçon 10 extérieur, supportant les axes de guidage 19 et les ressorts de montage élastique 16 du poinçon 7, et monté lui-même, concentriquement dans le poinçon de soudage 18, à coulissement contre l'action de ressorts 21 avec guidage sur des axes 22
Dans cette conformation, le dispositif permet la mise en oeuvre de la variante du procédé, dans laquelle le complexe est d'abord pressé par le poinçon 7 dans la gorge 6 puis le bord du tissu est pressé dans la gorge 8 avant soudage dans cette dernière, le poinçon de soudage 18 correspondant, dans ce cas, au poinçon de soudage 11 suivant la figure ld.According to another characteristic of the invention, the device is advantageously provided with two concentric pressing punches, namely an inner punch 7 and an outer punch 10, supporting the guide pins 19 and the elastic mounting springs 16 of the punch 7 , and mounted itself, concentrically in the welding punch 18, sliding against the action of springs 21 with guidance on axes 22
In this configuration, the device allows the implementation of the variant of the method, in which the complex is first pressed by the punch 7 in the groove 6 then the edge of the fabric is pressed in the groove 8 before welding in the latter , the welding punch 18 corresponding, in this case, to the welding punch 11 according to FIG. 1d.

Comme le montre la figure 3 des dessins annexés, le panneau 2 est disposé sur un appui périphérique de l'élément 12 permettant son précentrage, ledit élément 12 se déplaçant et s'emboîtant dans la matrice 15 avec le complexe destiné à former le médaillon 1 et les différents poinçons 7, 10 et 18. As shown in Figure 3 of the accompanying drawings, the panel 2 is disposed on a peripheral support of the element 12 allowing its pre-centering, said element 12 moving and fitting into the matrix 15 with the complex intended to form the medallion 1 and the various punches 7, 10 and 18.

Bien entendu, de manière connue, les différents éléments constituant le médaillon 1 sont préalablement munis, sur leurs faces de contact entre eux et avec le panneau 2, d'un adhésif polymérisable qui est réactivable ou non par haute fréquence après soudage des bords du tissu dans la gorge périphérique 8. Ledit adhésif, situé sur la face de la mousse tournée vers le panneau ne devra pas être disposé dans la zone comprise entre les deux gorges périphériques de pressage et de soudage. Of course, in known manner, the various elements constituting the medallion 1 are previously provided, on their contact faces with one another and with the panel 2, with a polymerizable adhesive which can be reactivated or not by high frequency after welding the edges of the fabric in the peripheral groove 8. Said adhesive, located on the face of the foam facing the panel, must not be placed in the area between the two peripheral pressing and welding grooves.

L'invention a également pour objet un panneau, ou analogue, préformé, muni d'un médaillon 1 relié, par la périphérie du tissu le constituant et dépassant la périphérie de la mousse, au panneau 2 pourvu de deux gorges concentriques 6 et 8 dont la gorge extérieure 8 correspond au pourtour de la mousse constituant le médaillon 1, par un joint de soudage invisible disposé au fond de la gorge de plus grand développement 8 (figure 2). The invention also relates to a panel, or the like, preformed, provided with a medallion 1 connected, by the periphery of the fabric constituting it and projecting beyond the periphery of the foam, to the panel 2 provided with two concentric grooves 6 and 8 of which the outer groove 8 corresponds to the periphery of the foam constituting the medallion 1, by an invisible welding joint placed at the bottom of the groove of greatest development 8 (FIG. 2).

Grâce au procédé et au dispositif conformes à l'invention, il est possible d'utiliser, pour la réalisa tion du médaillon, une large gamme de tissu, du fait que le complexe formant ledit médaillon peut être centré de manière particulièrement précise et qu'il peut être maintenu en position, en particulier lors du soudage, de telle manière qu'une interposition néfaste de mousse entre le tissu et le fond de la gorge périphérique extérieure est évité. En outre, les procédé et dispositif conformes à l'invention permettent une adaptation à toutes formes de panneaux, à savoir convexes, plans, etc... Thanks to the method and the device according to the invention, it is possible to use, for the realization of the medallion, a wide range of fabric, since the complex forming said medallion can be centered in a particularly precise manner and that it can be held in position, in particular during welding, so that harmful interposition of foam between the fabric and the bottom of the outer peripheral groove is avoided. In addition, the methods and device in accordance with the invention allow adaptation to all forms of panels, namely convex, planes, etc.

Le procédé conforme à l'invention est de mise en oeuvre simple et rapide, permet une économie de matière appréciable par rapport aux procédés utilisés à ce jour et permet la réalisation de pièces d'un aspect impeccable. The process according to the invention is simple and quick to implement, allows a considerable saving of material compared to the processes used to date and allows the production of parts with an impeccable appearance.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.  Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
