Description

La présente invention concerne tout d'abord un procédé de réalisation d'une structure tridimensionnelle, ornementale ou utilitaire.The present invention relates first of all to a method of producing a three-dimensional, ornamental or utility structure.

Il s'agit surtout d'un procédé à l'attention des enfants, destiné à éveiller leurs qualités manuelles, et qui ne néglige pas pour autant le développement de leur perception spatiale des choses, ni de leurs facultés d'association. Il s'agit aussi d'offrir à ces enfants les moyens de réaliser par eux-mêmes une oeuvre matérielle, ornementale ou utilitaire et de leur inculquer le goût du travail bien fait.It is above all a process intended for children, intended to awaken their manual qualities, and which does not neglect the development of their spatial perception of things, nor of their faculties of association. It is also a question of offering these children the means to carry out by themselves a material, ornamental or utilitarian work and to instill in them the taste for work well done.

A cet effet, la présente invention concerne un procédé de réalisation d'une structure tridimensionnelle, caractérisé par le fait qu'on projette cette structure selon au moins une direction déterminée pour obtenir au moins une projection sur une surface plane, on trace sur cette surface et à l'intérieur de la projection obtenue des courbes représentatives du relief de la structure, on prédécoupe cette projection et ces courbes de relief, on isole les différentes portions de la surface comprises entre deux des courbes de relief, on éloigne ces portions deux à deux l'une de l'autre selon la direction de projection initiale, on maintient séparées ces portions dans leur position relative à l'aide de moyens de séparation appropriés, puis on fixe ces portions dans cette position pour reconstituer la structure à réaliser.To this end, the present invention relates to a method for producing a three-dimensional structure, characterized in that this structure is projected in at least one determined direction to obtain at least one projection on a flat surface, we trace on this surface and inside the projection obtained from the curves representative of the relief of the structure, this projection and these relief curves are precut, the different portions of the surface between two of the relief curves are isolated, these portions are moved away two to two from each other in the initial direction of projection, these portions are kept separate in their relative position using appropriate separation means, then these portions are fixed in this position to reconstitute the structure to be produced.

Grâce au procédé de l'invention, l'enfant doit au moins associer les portions de relief de la structure à réaliser deux à deux, les superposer convenablement dans l'espace et les fixer dans cette position. Il s'agit pratiquement d'un puzzle dans l'espace, où toutefois, au lieu d'avoir à encastrer deux pièces l'une dans l'autre sur une surface plane, il faut pratiquement superposer deux portions l'une au-dessus de l'autre, avec interposition des moyens L'invention permet de réaliser toutes sortes d'objets, utilitaires d'abord, comme des cendriers, des vases, des coupes, ornementaux ensuite, comme des statuettes en forme d'animaux, par exemple.Thanks to the method of the invention, the child must at least combine the raised portions of the structure to be produced two by two, superimpose them properly in space and fix them in this position. It is practically a puzzle in space, where however, instead of having to embed two pieces one inside the other on a flat surface, it is practically necessary to superimpose two portions one above on the other, with the interposition of means The invention makes it possible to produce all kinds of objects, utility first, such as ashtrays, vases, bowls, then ornamental, like statuettes in the shape of animals, for example.

Dans une mise en oeuvre préférée du procédé de l'invention, on projette au moins en deux endroits distincts sur la même surface plane, selon au moins une direction déterminée, la structure à réaliser et on trace, à l'intérieur des deux projections obtenues, respectivement deux séries de courbes de relief, les courbes d'une des deux séries de courbes pouvant être intercalées entre deux des courbes adjacentes de l'autre série, pour obtenir deux séries de portions de relief, et on utilise les portions de l'une des deux séries de portions comme moyens de séparation des portions de l'autre série.In a preferred implementation of the method of the invention, the structure to be produced is projected at least in two separate places onto the same flat surface, in at least one determined direction, and the two projections obtained are plotted , respectively two series of relief curves, the curves of one of the two series of curves being able to be inserted between two of the adjacent curves of the other series, to obtain two series of relief portions, and the portions of the one of the two series of portions as means for separating the portions of the other series.

Dans ce cas, et avec une seule surface plane, on peut reconstituer aisément la structure à réaliser, d'ailleurs sans la moindre chute.In this case, and with a single flat surface, one can easily reconstitute the structure to be produced, moreover without the slightest fall.

L'invention concerne également un canevas pour la mise en oeuvre du procédé de l'invention, caractérisé par le fait qu'il y est tracé, au moins en deux endroits distincts, deux projections, selon au moins une direction déterminée, de la structure à réaliser et, à l'intérieur des deux projections, deux séries de courbes de relief, respectivement, les courbes d'une des deux séries pouvant être intercalées entre deux des courbes adjacentes de l'autre série.The invention also relates to a canvas for implementing the method of the invention, characterized in that it is traced there, at least in two separate places, two projections, in at least one determined direction, of the structure to be produced and, inside the two projections, two series of relief curves, respectively, the curves of one of the two series being able to be inserted between two of the adjacent curves of the other series.

Dans une forme de réalisation préférée du canevas de l'invention, les projections et les courbes de relief sont prédécoupées.In a preferred embodiment of the canvas of the invention, the projections and the relief curves are precut.

Il est avantageux que les courbes de relief soient des courbes de niveau.It is advantageous that the relief curves are contour lines.

L'invention sera mieux comprise à l'aide de la description suivante d'une forme de réalisation particulière du canevas de l'invention et de la mise en oeuvre du procédé de l'invention correspondante, en référence au dessin annexé, sur lequel :

  • - la figure 1 représente une vue en plan du canevas de l'invention, et
  • - la figure 2 représente une vue en perspective de la structure réalisée à partir du canevas de la figure 1.
The invention will be better understood using the following description of a particular embodiment of the canvas of the invention and the implementation of the method of the corresponding invention, with reference to the appended drawing, in which:
  • FIG. 1 represents a plan view of the canvas of the invention, and
  • - Figure 2 shows a perspective view of the structure made from the canvas of Figure 1.

La figure représente un canevas pour réaliser une structure ou, mieux, une demi-structure, de poisson en relief.The figure represents a canvas for making a structure or, better, a half-structure, of fish in relief.

Ce canevas est divisé en deux parties 1 et 2 comportant chacune une série de courbes prédécoupées obtenues par projection, selon une direction perpendiculaire à la surface du canevas, de la structure en forme de poisson à réaliser, cette structure étant, pour les deux projections considérées, disposée dans la même orientation spatiale. Dans le cas représenté, il s'agit d'une représentation latérale du poisson. La partie 1, en bas de la figure, comporte une courbe extérieure 10, correspondant au contour extérieur du poisson, et des courbes intérieures. Au niveau du corps du poisson, par exemple, sont tracées des courbes 12, 14, 16, 18 qui vont constituer, une fois la structure tridimensionnelle réalisée, des courbes ou arêtes de niveau. Ces courbes sont sensiblement équidistantes. Elles délimitent deux à deux des portions ou bandes de relief 20, 22, 24, 26, la courbe centrale 18 délimitant à elle seule une portion de relief 28.This canvas is divided into two parts 1 and 2 each comprising a series of precut curves obtained by projection, in a direction perpendicular to the surface of the canvas, of the fish-shaped structure to be produced, this structure being, for the two projections considered , arranged in the same spatial orientation. In the case shown, it is a lateral representation of the fish. Part 1, at the bottom of the figure, has an external curve 10, corresponding to the external contour of the fish, and internal curves. At the level of the body of the fish, for example, curves 12, 14, 16, 18 are drawn which will constitute, once the three-dimensional structure produced, level curves or edges. These curves are substantially equidistant. They delimit two by two of the portions or bands of relief 20, 22, 24, 26, the central curve 18 alone delimiting a portion of relief 28.

La partie 2, en haut de la figure, comporte une série de courbes aussi sensiblement équidistantes, par exemple 11, 13, 15, 17, 19 au niveau du corps du poisson, qui vont constituer, une fois la structure tridimensionnelle réalisée, des courbes de niveau respectivement intercalées entre deux des courbes de niveau de la partie 1 du canevas. Ainsi, la courbe 11 de la partie 2 est destinée à être intercalée entre les courbes 10 et 12 de la partie 1, la courbe 13 de la partie 2 entre les courbes 12 et 14 de la partie 1, comme représenté en traits mixtes sur la partiel 1 de la figure.Part 2, at the top of the figure, comprises a series of curves which are also substantially equidistant, for example 11, 13, 15, 17, 19 at the level of the body of the fish, which will constitute, once the three-dimensional structure realizes sée, contour lines respectively interspersed between two of the contour lines in part 1 of the canvas. Thus, curve 11 of part 2 is intended to be inserted between curves 10 and 12 of part 1, curve 13 of part 2 between curves 12 and 14 of part 1, as shown in phantom on the Part 1 of the figure.

Les courbes 11, 13, 15, 17, 19 de la partie 2 du canevas délimitent deux à deux des bandes de relief 21, 23, 25, 27 destinées à être intercalées entre deux bandes de relief issues de la partie 1 du canevas ou, en d'autres termes, à être respectivement superposées sur une bande de relief de la partie 1 du canevas et correspondant à un niveau inférieur.The curves 11, 13, 15, 17, 19 of part 2 of the canvas delimit two by two of the relief bands 21, 23, 25, 27 intended to be interposed between two relief bands coming from part 1 of the canvas or, in other words, to be respectively superimposed on a relief strip of part 1 of the canvas and corresponding to a lower level.

Le canevas représentée sur la figure 1 est caractérisé en ce qu'une courbe de relief ou de niveau d'une partie peut toujours être intercalée entre deux courbes adjacentes de l'autre partie, si bien que la portion ou bande de relief ou de niveau correspondant à la courbe intercalaire peut prendre appui sur la bande correspondant aux deux courbes adjacentes et élever ainsi la structure d'une hauteur correspondant à l'épaisseur du canevas.The canvas shown in Figure 1 is characterized in that a relief or level curve of one part can always be interposed between two adjacent curves of the other part, so that the portion or strip of relief or level corresponding to the intermediate curve can rest on the strip corresponding to the two adjacent curves and thus raise the structure by a height corresponding to the thickness of the canvas.

A cet égard, on a considéré un canevas formé de deux parties. Mais il est clair que l'invention n'est pas limitée à un tel canevas et qu'on pourrait envisager un canevas formé de trois parties et plus. Dans ce Cas, entre deux courbes adjacentes d'une même partie pourraient s'intercaler deux courbes, ou plus, appartenant respectivement aux deux autres parties, avec pour effet d'augmenter plus rapidement le relief de l'objet à réaliser.In this regard, we considered a framework made up of two parts. But it is clear that the invention is not limited to such a canvas and that one could envisage a canvas formed of three parts and more. In this case, between two adjacent curves of the same part, two or more curves could be inserted, belonging respectively to the two other parts, with the effect of increasing the relief of the object to be produced more quickly.

Par ailleurs, on a, dans le cas représenté, considéré des courbes de niveau sensiblement équidistantes. L'invention bien entendu n'est pas limitée à une telle caractéristique. Dans le cas où ces courbes sont effectivement équidistantes, le relief de la structure tridimensionnelle réalisée est du type conique à génératrice rectiligne. Si on désire obtenir un relief sphrique ou autre, il suffit de prévoir des courbes de niveau non équidistantes, étant entendu que l'épaisseur de chaque niveau intercalaire dans la structure finale reste égale à l'épaisseur du canevas.Furthermore, we have, in the case shown, considered substantially equidistant contours. The invention of course is not limited to such a characteristic. In the case where these curves are effectively equi distant, the relief of the three-dimensional structure produced is of the conical type with a straight generator. If it is desired to obtain a spherical or other relief, it suffices to provide non-equidistant contour lines, it being understood that the thickness of each intermediate level in the final structure remains equal to the thickness of the canvas.

En outre, les courbes prédécoupées sur le canevas de l'invention sont bien destinées à former des courbes de niveau de la structure finale réalisée, en raison du fait que le canevas est plan. Il est clair que ces courbes de niveau ne correspondent pas forcément à des courbes de niveau de la structure projetée de base, et c'est pourquoi elles ont été désignées sous le nom de courbes de relief. Ces courbes de relief peuvent évidemment être des courbes de niveau, c'est-à-dire s'étendant dans des plans parallèles, mais ce n'est pas une condition limitative de l'invention.In addition, the precut curves on the canvas of the invention are indeed intended to form level curves of the final structure produced, due to the fact that the canvas is planar. It is clear that these contour lines do not necessarily correspond to contour lines of the basic projected structure, and that is why they have been designated as relief curves. These relief curves can obviously be contour lines, that is to say extending in parallel planes, but this is not a limiting condition of the invention.

D'autre part, toutes les courbes de niveau du canevas représenté sont sensiblement homothétiques les unes des autres. Il ne s'agit pas là encore d'une condition impérative.On the other hand, all the contour lines of the represented canvas are substantially homothetic to each other. Again, this is not an imperative condition.

De plus, la projection de la structure à réaliser dans l'espace, dans le cas considéré, a été effectuée selon une direction perpendiculaire au canevas. On pourrait imaginer également une projection oblique. On pourrait aussi prévoir, dans des cas particuliers, qu'un canevas selon l'invention comporte une première série de courbes de projection suivant une direction et une deuxième série de courbes de projection suivant une autre direction.In addition, the projection of the structure to be produced in space, in the case considered, was carried out in a direction perpendicular to the canvas. One could also imagine an oblique projection. One could also provide, in particular cases, that a canvas according to the invention comprises a first series of projection curves in one direction and a second series of projection curves in another direction.

Enfin, l'invention n'est naturellement pas limitée à la réalisation de structures ne possédant qu'un seul contour extérieur. On pourrait ainsi prévoir de réaliser des objets creux, percés ou troués, possédant au moins deux contours extérieurs, profils ou gabarits, comme par exemple un tore. Dans ce cas, l'une des courbes de relief ou de niveau deviendrait une deuxième projection au sens défini plus haut.Finally, the invention is naturally not limited to the production of structures having only one external contour. It would thus be possible to provide for hollow objects, drilled or perforated, having at least two external contours, profiles or templates, such as for example a torus. In this case, one of the relief or level would become a second projection in the sense defined above.

A partir du canevas qui a été décrit plus haut, et pour la réalisation de la structure, on isole les bandes de niveau des deux parties du canevas, on prend la bande 20 de la partie 1, donc éloignée de la bande 22 de cette même partie, on superpose verticalement la bande 21 de la partie 2 sur la bande 20, puis on superpose de la même manière la bande 22 de la partie 1 sur la bande 21 de la partie 2 qui maintient ainsi séparées les deux bandes 20 et 22 de la partie 1, et ainsi de suite, pour obtenir la structure tridimensionnelle du corps du poisson. On répète ces opérations pour la tête, la queue et les nageoires du poisson, avant de fixer en position toutes les bandes de relief du poisson.From the canvas which was described above, and for the realization of the structure, we isolate the level strips of the two parts of the canvas, we take the strip 20 from part 1, therefore distant from the strip 22 of this same part, the strip 21 of part 2 is vertically superimposed on the strip 20, then the strip 22 of part 1 is superimposed in the same way on the strip 21 of part 2 which thus keeps the two strips 20 and 22 separate. part 1, and so on, to get the three-dimensional structure of the body of the fish. These operations are repeated for the head, the tail and the fins of the fish, before fixing in position all the relief bands of the fish.

La fixation des bandes de niveau peut être avantageusement réalisée à la colle, le canevas pouvant être proposé, par exemple, en carton, bois ou matière plastique. Les différentes bandes de niveau peuvent enfin être avantageusement peintes.The fixing of the level strips can advantageously be carried out with glue, the canvas being able to be proposed, for example, in cardboard, wood or plastic. The different level strips can finally be advantageously painted.
