Description

La présente invention concerne une feuille présentant des pliures prédéterminées.The present invention relates to a sheet having folds predetermined.

Elle se rapporte, plus particulièrement, à une telle feuille destinée au support d'un jeu ayant pour but de plier successivement ladite feuille, éventuellement, suivant plusieurs épaisseurs afin de reconstituer les mosaïques dessinées sur les deux côtés de la feuille.It relates, more particularly, to such a sheet intended for support of a game intended to successively fold said sheet, possibly, according to several thicknesses in order to reconstitute the mosaics drawn on both sides of the sheet.

On connaít déjà une telle feuille, constituée à partir d'une mince feuille de papier présentant la forme d'un hexagone réalisée à partir de triangles équilatéraux disposés tête bêche sur plusieurs lignes et liés entre-eux par leurs côtés. Afin de faciliter le pliage de la feuille, chaque ligne de liaison, qui forme par ailleurs la ligne de pliage, est constituée d'une succession de perforations ou de rainurages linéaires régulièrement espacées.We already know such a sheet, made from a thin sheet of paper in the shape of a hexagon made from triangles equilateral arranged head to tail on several lines and linked together by their sides. In order to facilitate the folding of the sheet, each connecting line, which forms by elsewhere the fold line, consists of a succession of perforations or regularly spaced linear grooves.

L'inconvénient majeur de ce type de liaison réside dans le fait qu'après un usage modéré dans le cas par exemple d'un tel jeu, c'est-à-dire d'une pluralité de pliage pour réaliser les mosaïques, les lignes de liaison, pour certain type de papier, se déchirent entraínant par voie de conséquence la destruction du jeu.The major drawback of this type of bond lies in the fact that after a moderate use in the case for example of such a game, that is to say of a plurality of folding to make mosaics, connecting lines, for certain types of paper, tear causing consequent destruction of the game.

Par ailleurs, il s'avère également que lors de pliages successives, la surépaisseur du papier ne permet pas de mettre en coïncidence les différentes formes géométriques afin de reconstituer notamment la représentation graphique.Furthermore, it also turns out that during successive folds, the extra thickness of the paper does not allow to coincide the different geometric shapes in order to reconstruct in particular the representation graphic.

Le but de l'invention est de proposer une feuille du type décrit ci-dessus qui permette de résoudre les inconvénients précités.The object of the invention is to propose a sheet of the type described above which solves the aforementioned drawbacks.

A cet effet, la présente invention a pour objet une feuille présentant des pliures prédéterminées constituée d'une plaque recouverte de chaque côté par un matériau plastique, caractérisée en ce que ladite plaque est pourvue d'une pluralité de formes géométriques espacées les unes des autres et reliées entre-elles par des pontets de liaisons formant lignes de pliage.To this end, the present invention relates to a sheet having predetermined folds consisting of a plate covered on each side by a plastic material, characterized in that said plate is provided with a plurality of geometrical shapes spaced from each other and linked together by connecting bridges forming fold lines.

Suivant quelques dispositions intéressantes de l'invention:

  • la plaque présente la forme d'un hexagone et en ce que les formes géométriques sont des triangles équilatéraux disposées tête bêche suivant une ligne ;
  • les triangles sont associés respectivement les uns aux autres par l'intermédiaire d'au moins deux pontets de liaison sur un triangle ;
  • les pontets de liaisons sont disposés respectivement au milieu de chaque côté d'un triangle ;
  • la longueur des pontets est définie de telle manière que celle-ci est au moins égale à un vingtième de la longueur d'un côté du triangle ;
  • l'espace entre deux formes géométriques est déterminée en fonction du grammage du matériau utilisé pour réaliser la plaque ;
  • chaque triangle est pourvu sur sa face d'une représentation graphique.
According to some interesting features of the invention:
  • the plate has the shape of a hexagon and in that the geometric shapes are equilateral triangles arranged head to tail along a line;
  • the triangles are associated with each other respectively by means of at least two connecting bridges on a triangle;
  • the connecting bridges are arranged respectively in the middle of each side of a triangle;
  • the length of the bridges is defined in such a way that it is at least equal to one twentieth of the length of one side of the triangle;
  • the space between two geometric shapes is determined according to the grammage of the material used to make the plate;
  • each triangle is provided on its face with a graphic representation.

Les caractéristiques de l'invention mentionnées ci-dessus, ainsi que d'autres, apparaítront plus clairement à la lecture de la description suivante d'un exemple de réalisation, en se référant aux dessins annexés sur lesquels:

  • la figure 1 est une vue de face d'une feuille selon la présente invention, et
  • la figure 2 est une vue de côté de la feuille selon la figure 1.
The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the following description of an exemplary embodiment, with reference to the accompanying drawings in which:
  • FIG. 1 is a front view of a sheet according to the present invention, and
  • FIG. 2 is a side view of the sheet according to FIG. 1.

On a représenté à la figure 1, une feuille présentant des pliures prédéterminées selon un mode de réalisation particulier de la présente invention dans le cadre d'une application à un jeu de pliage du type « casse tête ».There is shown in Figure 1, a sheet having folds predetermined according to a particular embodiment of the present invention in the context of an application to a folding game of the “puzzle” type.

La feuille 1 est formée à partir d'une plaque 2 dans laquelle est réalisée une pluralité de triangles équilatéraux T1 à Tn disposées tête bêche suivant une ligne et agencés de manière à obtenir un hexagone. Chaque triangle étant pourvu sur chacune de ses faces d'une représentation graphique, non représentée.The sheet 1 is formed from a plate 2 in which is made a plurality of equilateral triangles T1 to Tn arranged head to tail in a line and arranged so as to obtain a hexagon. Each triangle being provided on each of its faces with a graphic representation, not represented.

Selon l'invention, les triangles sont espacés entre eux d'une distance d, comme visible à la figure 1, et associés respectivement les uns aux autres par l'intermédiaire d'au moins deux pontets P1, P2 de liaison sur un triangle disposés respectivement au milieu de chaque côté de ce demier.According to the invention, the triangles are spaced apart by a distance d, as shown in Figure 1, and associated with each other by through at least two bridges P1, P2 connecting on a triangle arranged respectively in the middle of each side of the latter.

On comprend aisément que les triangles Tn disposés autour de la feuille 1 ne soient pourvus que de deux pontets ceux-ci n'étant voisin que de deux triangles, tandis que les autres sont pourvus de trois pontets de liaison Pn étant associé à trois triangles. It is easily understood that the triangles Tn arranged around the sheet 1 are only provided with two jumpers, these being only close to two triangles, while the others are provided with three connecting bridges Pn being associated with three triangles.

Avantageusement, la longueur des pontets est définie de telle manière que celle-ci est au moins égale à un vingtième de la longueur d'un côté du triangle.Advantageously, the length of the bridges is defined in such a way that this is at least equal to one twentieth of the length of one side of the triangle.

Par ailleurs, selon le choix de la plaque, réalisée de préférence soit dans du carton ou dans du papier épais, l'espace d et par conséquent la largeur des pontets Pn varie en fonction du grammage du matériau utilisé et est adapté de manière à permettre un pliage d'une ligne sur l'autre des plus aisé.Furthermore, depending on the choice of plate, preferably made either in of cardboard or thick paper, the space d and therefore the width of the bridges Pn varies according to the grammage of the material used and is adapted to so as to allow folding of a line on the other of the easiest.

De même, on notera que le découpage des différents triangles Tn à l'intérieur de la plaque 2 est obtenu avantageusement par une découpe au laser permettant un gain de temps et une rapidité d'exécution de la manoeuvre.Similarly, it will be noted that the division of the different triangles Tn to the inside of the plate 2 is advantageously obtained by laser cutting saving time and speed of execution of the maneuver.

La plaque 2, ainsi, réalisée est ensuite recouverte entièrement sur chacune de ces faces d'un matériau du type film plastique mince 3, 3', comme visible à la figure 2, destiné à rigidifier la plaque 1.The plate 2, thus produced, is then completely covered on each of these faces of a material of the thin plastic film type 3, 3 ′, as visible on the Figure 2, intended to stiffen the plate 1.

La mise en place de ce film plastique 3, 3' est obtenue de manière traditionnelle par un laminage à chaud de la plaque 2 entre les deux films plastiques.The establishment of this plastic film 3, 3 'is obtained so traditional by hot rolling of plate 2 between the two films plastics.

On comprend à la lecture de la description ci-dessus que la feuille 1 selon l'invention est relativement simple à réaliser de par la présence des pontets offrant une réalisation de la plaque monopièce et permet une liaison de pliage très résistante de par les caractéristiques des films plastiques.It is understood from reading the description above that sheet 1 according to the invention is relatively simple to carry out by the presence of the bridges offering a one-piece plate construction and allows a folding connection very resistant due to the characteristics of plastic films.

Bien que l'invention ait été décrite en liaison avec un mode de réalisation particulier dans le cadre d'une application à un jeu, elle comprend tous les équivalents techniques des moyens décrits.Although the invention has been described in connection with an embodiment particular in the context of a game application, it includes all technical equivalents of the means described.

Ainsi, la plaque 2 peut être constitué d'une autre forme géométrique que des triangles équilatéraux, tel que par exemple des carrés définissant dans un tel cas que deux axes de pliage An au lieu de trois dans le cas des triangles équilatéraux. De même, elle peut comporter une multitude de forme géométrique.Thus, the plate 2 can be made up of another geometric shape than equilateral triangles, such as for example squares defining in such case that two folding axes An instead of three in the case of triangles equilateral. Similarly, it can include a multitude of geometric shapes.

La présente invention trouve donc une application dans tout dispositif nécessitant des pliages résistants, tel que par exemple les chemises de protection de documents ou autres.The present invention therefore finds application in any device requiring strong folds, such as for example shirts document or other protection.
