Abstract
Description
Procédé Pour la réalisation à la surface d'un objet d'un décor en relief du type guillochis et objets porteurs d'un tel décor. Process For the production on the surface of an object of a relief decoration of the guilloche type and objects carrying such a decoration.
La présente invention concerne un procédé pour la réalisation à la surface d'un objet d'un décor en relief du type guillochis, à effet esthétique amélioré. L'invention concerne également les objets porteurs d'un tel décor. The present invention relates to a method for producing on the surface of an object a relief decoration of the guilloche type, with improved aesthetic effect. The invention also relates to objects carrying such a decoration.
On sait que l'on désigne, par le terme de guillochis, un décor fonné d'un ensemble de rainures plus ou moins fines, parallèles dans leur forme de réalisation la plus simple, gravées sur la surface d'un objet. Dans des formes de réalisations plus élaborées, ces rainures peuvent avoir un profil courbe, de façon à former tel ou tel rnotif particulier. We know that we designate, by the term guilloche, a decoration formed from a set of more or less fine grooves, parallel in their simplest embodiment, engraved on the surface of an object. In more elaborate embodiments, these grooves can have a curved profile, so as to form such or such a particular motif.
Ce type de décor est très utilisé pour habiller des objets d'orfèvrerie, car, suivant leur configuration et les conditions de l'éclairage ambiant, certaines des faces de ces rainures réfléchissent ou non la lumière incidente vers l'observateur et apparaissent ainsi à celui-ci respectivement claires ou sombres. This type of decoration is widely used to dress objects of goldsmithery, because, according to their configuration and the conditions of the ambient lighting, some of the faces of these grooves reflect or not the incident light towards the observer and thus appear to that - respectively light or dark.
Lorsque l'utilisateur fait pivoter le décor autour d'un axe sensiblement parallèle aux rainures fonnant le réseau, il peut observer, à partir d'un certain angle de rotation, une permutation entre les zones claires et les zones sombres. Une telle permutation se produisant entre des zones de largeur relativement réduite est insuffisante pour donner à l'utilisateur une quelconque ù.rpression de mouvement. When the user rotates the decoration around an axis substantially parallel to the grooves forming the network, he can observe, from a certain angle of rotation, a permutation between the light areas and the dark areas. Such a permutation occurring between areas of relatively reduced width is insufficient to give the user any sense of movement.
La présente invention propose un guillochis qui, lorsqu'il est mis en oeuvre sur la surface d'un objet, est tel que, lorsqu'on imprime une rotation à cet objet, la permutation entre zones claires et zones sombres résultant de cette rotation crée une irçression de mouvement conférant au décor un caractère cinétique. The present invention provides a guilloche which, when implemented on the surface of an object, is such that, when a rotation is printed on this object, the permutation between light and dark zones resulting from this rotation creates an irresistible movement giving the decor a kinetic character.
A cet effet, l'invention a pour objet un procédé pour la réalisation sur la surface d'un objet d'un décor en relief du type guillochis, ce procédé étant caractérisé en ce que l'on forme sur ladite surface un ensemble d'au moins deux réseaux constitués chacun d'au moins deux rainures de section en V identiques, les angles fondés par au moins l'une des deux faces correspondantes de deux rainures apparténant à des réseaux différents avec ladite surface étant différents. To this end, the subject of the invention is a method for producing on the surface of an object a relief decoration of the guilloche type, this method being characterized in that a set of at least two networks each consisting of at least two identical V-shaped grooves, the angles founded by at least one of the two corresponding faces of two grooves belonging to different networks with said surface being different.
L'invention concerne également des objets dont au moins une partie de la surface comporte un décor en relief du type guillochis, ces objets étant caractérisés en ce que le guillochis de ladite surface comporte au moins deux réseaux constitués chacun d'au moins deux rainures de section en V identiques, au moins l'une des faces correspondantes des deux rainures appartenant à chacun desdits réseaux faisant un angle différent avec ladite surface. The invention also relates to objects of which at least part of the surface comprises a relief decoration of the guillochis type, these objects being characterized in that the guillochis of said surface comprises at least two networks each consisting of at least two grooves of identical V-section, at least one of the corresponding faces of the two grooves belonging to each of said networks making a different angle with said surface.
Dans un tel décor, les faces correspondantes de rainures appartenant à deux réseaux distincts formant avec la surface de base des angles différents réfléchiront les rayons lumineux incidents sous des angles différents. C'est donc pour une orientation différente de la surface de guillochis que les rayons lumineux réfléchis par les deux réseaux de-rainures rencontrent l'oeil de l'observateur. La différence angulaire introduite, suivant l'invention, entre les faces correspondantes de rainures appartenant à des réseaux différents permet d'étendre au niveau du réseau des permutations entre zones claires et zones sombres n'existant précédemment qu'au niveau de la rainure. De ce fait, le caractère cinétique de l'effet visuel produit est considérablement amélioré. In such a setting, the corresponding faces of grooves belonging to two distinct networks forming with the base surface different angles will reflect the incident light rays from different angles. It is therefore for a different orientation of the guilloche surface that the light rays reflected by the two networks of grooves meet the eye of the observer. The angular difference introduced, according to the invention, between the corresponding faces of grooves belonging to different networks makes it possible to extend, at the level of the network, permutations between light zones and dark zones which previously existed only at the level of the groove. As a result, the kinetic nature of the visual effect produced is considerably improved.
Avantageusement, les rainures de deux réseaux voisins seront symétriques par rapport à un plan perpendiculaire au plan de ladite surface. Advantageously, the grooves of two neighboring networks will be symmetrical with respect to a plane perpendicular to the plane of said surface.
Afin d'accroître l'aspect décoratif d'un tel guillochis, on pourra prévoir un second ensemble d'au moins deux réseaux de rainures, constitués chacun, comne pour le premier réseau, d'au moins deux rainures de section en V identiques, au moins 1 'une des faces correspondantes des deux rainures appartenant à chacun desdits réseaux du second ensemble faisant un angle différent avec ladite surface, les rainures formant ce second ensemble étant sécantes de celles du premier ensemble. In order to increase the decorative aspect of such a guilloche, a second set of at least two networks of grooves may be provided, each consisting, as for the first network, of at least two grooves of identical V-section, at least one of the corresponding faces of the two grooves belonging to each of said networks of the second set making a different angle with said surface, the grooves forming this second set being intersecting from those of the first set.
Dans une réalisation intéressante de l'invention, les rainures constituant chacun de ces deux ensembles sont parallèles entre elles et sont perpendiculaires à celles de l'autre ensemble. In an interesting embodiment of the invention, the grooves constituting each of these two sets are mutually parallel and are perpendicular to those of the other set.
Naturellement, des variantes décoratives peuvent être conçues par l'homme de l'art sans sortir du cadre de l'invention. C'est ainsi, par exemple, que deux réseaux contigus de rainures pourront être séparés par une portion plane. Naturally, decorative variants can be designed by those skilled in the art without departing from the scope of the invention. Thus, for example, two contiguous networks of grooves can be separated by a flat portion.

Les figures 8 à 10 sont des vues de dessus d'autres formes de réalisation de guillochis selon l'invention ;
La figure 11 est une coupe schématique d'un guillochis conforme à l'invention formé sur une surface courbe.Figures 8 to 10 are top views of other embodiments of guillochis according to the invention;
Figure 11 is a schematic section of a guilloche according to the invention formed on a curved surface.
Le guillochis représenté sur les figures 1à 3 est constitué de deux réseaux formés de rainures parallèles de section en V, respectivement l et 2, couvrant chacun la moitié de la surface de l'objet à décorer. The guillochis shown in FIGS. 1 to 3 consists of two networks formed by parallel V-shaped grooves, respectively l and 2, each covering half of the surface of the object to be decorated.
Les faces 3 et 4 des rainures 1 du premier réseau forment avec le plan de base (c' est-à-dire un plan parallèle à la surface dans laquelle on a creusé le décor) des angles, respectivement d et alors que les faces correspondantes 5 et 6 des rainures 2 du second réseau forment avec le plan de base des angles, respectivement et Cfl. Ainsi, les rainures 1 et 2 de ces deux réseaux sont symétriques par rapport à un plan perpendiculaire au plan de base et figuré sur la coupe transversale de la figure 1 par la ligne I-I. The faces 3 and 4 of the grooves 1 of the first network form with the base plane (that is to say a plane parallel to the surface in which the decoration has been dug) angles, respectively d and while the corresponding faces 5 and 6 of the grooves 2 of the second network form with the base plane angles, respectively and Cfl. Thus, the grooves 1 and 2 of these two networks are symmetrical with respect to a plane perpendicular to the base plane and shown in the cross section of Figure 1 by the line I-I.
Les rayons lumineux incidents I1, qui rencontrent les faces 3 des rainures 1 du premier réseau se réfléchissent suivant une direction R1 et sont susceptibles d'être vus par un observateur disposé en X. Pour celui-ci, les faces 3 seront donc éclairées. The incident light rays I1, which meet the faces 3 of the grooves 1 of the first network are reflected in a direction R1 and are likely to be seen by an observer positioned at X. For this one, the faces 3 will therefore be lit.
Par contre, les rayons lumineux incidents I2, parallèles à Il, qui rencontrent les faces correspondantes 5 des rainures 2 du second réseau se réfléchissent suivant une direction R2 et ne seront pas vus par l'observateur placé en X. Pour celui-ci, les faces 5 seront donc sombres. Quant aux faces 4 et 6, on voit aisément qu'elles ne sont pas éclairées par le faisceau de rayons parallèles Il, 12. On the other hand, the incident light rays I2, parallel to II, which meet the corresponding faces 5 of the grooves 2 of the second network are reflected in a direction R2 and will not be seen by the observer placed at X. For this, the sides 5 will therefore be dark. As for the faces 4 and 6, it is easy to see that they are not illuminated by the beam of parallel rays Il, 12.
L'observateur voit ainsi la surface guillochée sous l'aspect représenté sur la figure 2, mais, s'il fait varier l'angle d'incidence des rayons lumineux, en faisant pivoter par exemple la surface de l'objet, ce sont les faces des rainures l qui lui paraîtront sombres et celles des rainures 2 qui apparaîtront éclairées, conrne représenté sur la figure 3. On obtient donc, au cours du mouvement de l'objet, un effet cinétique d'éclairage de la surface guillochée, sur laquelle les zones claires et sombres alternent et permutent. The observer thus sees the guilloche surface under the aspect represented in FIG. 2, but, if he varies the angle of incidence of the light rays, by rotating for example the surface of the object, these are the faces of the grooves l which will appear dark to it and those of the grooves 2 which will appear illuminated, as shown in FIG. 3. One therefore obtains, during the movement of the object, a kinetic effect of lighting the guilloche surface, on which light and dark areas alternate and swap.
iQaturellement, outre l'ensemble de réseaux de raiuures parallèles représentés sur les figures 1 à 3, la surface de l'objet peut coMprendre un second ensemble de réseaux de rainures parallèles, mais croisant le premier. Avantageusement, les rainures du second ensemble seront perpendiculaires à celles du premier ensemble, et l'on pourra ainsi obtenir des aspects complètement différents de la surface d'un mme objet, suivant qu'il est éclairé alternativement suivant deux directions perpendiculaires (flèches F et F' des figures 4 et 5), ou qu'il est éclairé simultanément suivant deux directions perpendiculaires, que l'on inverse ensuite (flèches F1 et F2 de la figure 6 et flèches F'1 et F'2 de la figure 7). iQururally, in addition to the set of networks of parallel grooves shown in FIGS. 1 to 3, the surface of the object can include a second set of networks of parallel grooves, but crossing the first. Advantageously, the grooves of the second set will be perpendicular to those of the first set, and it will thus be possible to obtain completely different aspects of the surface of the same object, depending on whether it is lit alternately in two perpendicular directions (arrows F and F 'in Figures 4 and 5), or that it is lit simultaneously in two perpendicular directions, which are then reversed (arrows F1 and F2 in Figure 6 and arrows F'1 and F'2 in Figure 7) .
Les rainures constituant les réseaux suivant l'invention ne sont pas exclusivement rectilignes et, comme montré sur les figures 8 à 10, peuvent prendre, au contraire, des formes courtes, de façon à former tel ou tel décor particulier. The grooves constituting the networks according to the invention are not exclusively rectilinear and, as shown in FIGS. 8 to 10, can, on the contrary, take short forms, so as to form such or such a particular decoration.
D'autre part, ce genre de décor peut être réalisé, corme montré sur la figure 11, sur des objets 10 dont la surface externe n'est pas plane, tels que, par exemple, des stbrlographes. On the other hand, this kind of decoration can be produced, corme shown in FIG. 11, on objects 10 whose external surface is not flat, such as, for example, stbrlographs.
Les réseaux de rainures conformes à l'illvention peuvent naturellement être réalisés par les moyens usuels de la technique et l'aspect cinétique original du guillochis selon l'invention est donc obtenu sans aucune majoration du coût des guillochis d'un type classique. The groove networks according to the invention can naturally be produced by the usual means of the technique and the original kinetic appearance of the guillochis according to the invention is therefore obtained without any increase in the cost of guillochis of a conventional type.
On notera que les décors du type guillochis conformes à l'invention peuvent être réalisés non seulement par guillochage, mais également par moulage, par fornage, etc.. It will be noted that the decorations of the guilloche type in accordance with the invention can be produced not only by guilloche, but also by molding, by forging, etc.
