Abstract

The assembly comprises: - on the one hand, an object 1 which derives, by distortion, from a shape which is known and identifiable per se, the distortions being such that, in the image 5 which gives of the object 1 a non-planar reflective surface 3 of defined geometry, they become optically cancelled out, and; - on the other hand, such a reflective surface 3. According to the invention, the distortions of the object 1 occur in the three dimensions of space.

Description

La présente invention concerne un ensemble de divertissement et/ou éducatif comprenant - d'une part, un objet dérivant, par distorsion, d'une forme en elle-même connue et identifiable, les distorsions étant telles que, dans l'image que donne de l'objet une surface réfléchissante, non plane, de géométrie déterminée, elles se trouvent optiquement annulées, et - d'autre part, une telle surface réfléchissante. The present invention relates to an entertainment and / or educational set comprising - on the one hand, an object derived, by distortion, from a form in itself known and identifiable, the distortions being such that, in the image that gives of the object a non-planar reflecting surface, of determined geometry, they are optically canceled, and - on the other hand, such a reflecting surface.

L'invention met ainsi en pratique le phénomène connu d'anamorphose. The invention thus puts into practice the known phenomenon of anamorphosis.

Les anamorphoses à miroir se sont développées à partir au XVIIème siècle jusqu'à devenir des objets de divertissement très répandus au XIXème siècle. Elles-utilisent, d'une part, des miroirs cylindriques, coniques, etc, et, comme objets, une oeuvre graphique ou picturale dont les formes ont été distordues de telle manière que l'oeuvre ne reprenne sa configuration véritable qu'en étant regardée dans un miroir. The mirror anamorphoses developed from the XVIIth century until becoming objects of entertainment very widespread in the XIXth century. They use, on the one hand, cylindrical, conical mirrors, etc., and, as objects, a graphic or pictorial work whose shapes have been distorted so that the work resumes its true configuration only when viewed in a mirror.

La présente invention a pour but de proposer, à des fins de divertissement et/ou d'éducation, un ensemble du type précité dans lequel les distorsions de l'objet s'exercent dans les trois dimensions de l'espace, l'objet étant ainsi tridimensionnel, et non plus bidimensionnel, comme dans les ensembles pour anamorphoses antérieurement connus. The object of the present invention is to propose, for entertainment and / or educational purposes, a set of the aforementioned type in which the distortions of the object are exerted in the three dimensions of space, the object being thus three-dimensional, and no longer two-dimensional, as in the previously known sets for anamorphoses.

L'objet, par rapport à la forme connue et identifiable de laquelle il dérive, revêt donc un aspect "grotesque" le rendant difficile à identifier en l'absence de la surface réfléchissante. The object, compared to the known and identifiable form from which it derives, therefore assumes a "grotesque" appearance making it difficult to identify in the absence of the reflecting surface.

On pourra donc utiliser une collection de tels objets dans le cadre de jeux pour enfants ou adultes qui devront tenter d'identifier les différents objets, la solution leur étant donnée ou leur étant confirmée par l'image que donne desdits objets la surface réfléchissante. We can therefore use a collection of such objects in the context of games for children or adults who will have to try to identify the different objects, the solution being given to them or being confirmed to them by the image that said objects give on the reflecting surface.

Le jeu pourra être compliqué en mêlant des objets dont les distorsions sont fonction d'une surface réfléchissante d'une première géométrie et au moins des objets dont les distorsions sont fonction d'une surface réfléchissante d'une seconde géométrie, le jeu pouvant consister cette fois, non seulement à identifier les objets, mais à les classer, au jugé, par géométrie de distorsion : il est bien entendu en effet que les distorsions seront différentes selon la géométrie de la surface réfléchissante adaptée à révéler la forme connue et identifiable. The game can be complicated by mixing objects whose distortions are a function of a reflective surface of a first geometry and at least objects whose distortions are a function of a reflective surface of a second geometry, the game being able to consist of times, not only to identify the objects, but to classify them, judged, by distortion geometry: it is indeed understood that the distortions will be different according to the geometry of the reflecting surface adapted to reveal the known and identifiable shape.

L'identification des objets à distorsions tridimensionnelles, sans avoir recours à la surface réfléchissante révélatrice, développera l'imagination des enfants et leur sens de la géométrie dans l'espace. Identifying objects with three-dimensional distortions, without resorting to the revealing reflective surface, will develop children's imagination and their sense of geometry in space.

I1 est bien entendu que l'objet à distorsions tridimensionnelles pourra être intégré dans un support qui, lui-même, ne comportera aucune distorsion. It is understood that the object with three-dimensional distortions can be integrated into a support which, itself, will not include any distortion.

La surface réfléchissante pourra être cylindrique, conique ou tronconique, -pyramidale ou en tronc de pyramide, en polygone régulier droit ou oblique, ou avoir toute autre forme, pourvu qu'elle ne soit pas plane. The reflecting surface may be cylindrical, conical or frustoconical, -pyramidal or in pyramidal trunk, in regular straight or oblique polygon, or have any other shape, provided that it is not planar.

L'invention est décrite ci-après en référence au dessin annexé dans lequel
-- la figure t est une vue de dessus d'un objet selon une forme d'exécution de l'invention destinée au domaine du divertissement pour les adultes, et
- la figure 2 est une vue en perspective dudit objet et de sa surface réfléchissante révélatrice.
The invention is described below with reference to the accompanying drawing in which
FIG. t is a top view of an object according to an embodiment of the invention intended for the field of entertainment for adults, and
- Figure 2 is a perspective view of said object and its revealing reflecting surface.

Si l'on se réfère à la figure 1, on voit un objet 1 de forme "grotesque" qu'il est relativement difficile d'identifier. If we refer to Figure 1, we see an object 1 of "grotesque" shape that is relatively difficult to identify.

La figure 2 montre un cylindre 2 dont la surface externe 3 est réfléchissante. Si l'on dispose ce cylindre 3 à l'intérieur de la zone 4 (figure 1) entourée par l'objet 1, on voit que la surface réfléchissante 3 donne de cet objet 1 une image 5 qui restitue une forme identifiable, en l'espèce un nu. On notera que les ombres et les plages de lumière de l'objet I étant, elles aussi, bien entendu réfléchies par la surface cylindrique 3, on obtient selon l'invention un effet de relief inconnu jusqu'ici avec les anamorphoses d'objets plans. FIG. 2 shows a cylinder 2 whose external surface 3 is reflective. If this cylinder 3 is placed inside the zone 4 (FIG. 1) surrounded by the object 1, we see that the reflecting surface 3 gives this object 1 an image 5 which restores an identifiable shape, in l 'a naked species. It will be noted that the shadows and the light ranges of the object I also being, of course, reflected by the cylindrical surface 3, there is obtained according to the invention a relief effect hitherto unknown with the anamorphoses of planar objects. .

I1 est bien entendu que la présente invention n'est pas limitée à la forme d'exécution décrite et représentée. En particulier, l'objet 1 et le cylindre 2 pourraient appartenir à des articles utilitaires. Par exemple, le cylindre 2, avec sa surface extérieure réfléchissante 3, pourrait être partie constitutive d'un récipient, tel qu'une tasse. It is understood that the present invention is not limited to the embodiment described and shown. In particular, the object 1 and the cylinder 2 could belong to utility articles. For example, the cylinder 2, with its reflective outer surface 3, could be part of a container, such as a cup.

L'objet I pourrait, lui, être incorporé, comme décor, dans un support tel qu'une soucoupe, ou constituer un objet autonome, par exemple former petite cuillère ou tout autre couvert. Object I could, for its part, be incorporated, as decoration, in a support such as a saucer, or constitute an autonomous object, for example forming a small spoon or any other cutlery.
