Abstract

The invention relates to a game that comprises basic cubes having on each surface a flush magnetic element. The cubes define a rigid volume via juxtaposition, stacking, and magnetisation. The surfaces of each magnetic element correspond to a first group including surfaces flush with the visible (6) and non-visible (7) surfaces of the basic cubes, and second group including sides flush with the neutral complementary surfaces (8) of the visible or non-visible surfaces of the basic cubes with which the surfaces of the first group are flush. The surfaces of the magnetic elements of at least one of the two groups have the same polarity. It is thus possible, by consecutive rotations or turnovers of sub-assemblies of the volume, to change the visual appearance of said volume.

Description

La présente invention concerne un jeu composé de petits cubes juxtaposés et superposables formant un ensemble volumique cohérent dans lequel des sous-ensembles peuvent être pivotés et retournés manuellement suivant des axes différents entraînant une modification de l'aspect extérieur et intérieur.The present invention relates to a set composed of small juxtaposed and superimposable cubes forming a coherent volume assembly in which subassemblies can be rotated and turned manually along different axes causing a change in the external and internal appearance.

On connaît traditionnellement des jeux d'assemblage d'éléments juxtaposables et superposables que l'on place l'un sur l'autre pour édifier divers objets ou figures. Le désagrément de ces jeux est que les cubes ne se tiennent pas entre eux ce qui a pour effet de rendre l'échafaudage instable.Juxtaposable and stackable elements assembling assemblies are traditionally known and placed on top of one another to construct various objects or shapes. The inconvenience of these games is that the cubes do not stand between them which has the effect of making the scaffolding unstable.

On connaît aussi des jeux où des éléments cubiques ou de forme parallélépipédique sont pourvus d'aimants sur une partie de leurs faces. Les aimants étant positionnés à la surface, il est alors possible d'échafauder des structures stables par empilement avec la possibilité de déplacement de sous-ensembles. On crée ainsi des jeux où interviennent la polarité des aimants, la couleur des faces ou même les relations des figures entre elles collées sur les faces.Games are also known where cubic or parallelepiped shaped elements are provided with magnets on part of their faces. Since the magnets are positioned on the surface, it is then possible to build up stable structures by stacking with the possibility of moving subsets. Thus, games are created in which the polarity of the magnets, the color of the faces or even the relations of the figures between them glued on the faces intervene.

On connaît surtout le jeu Rubik's Cube® qui par une mécanique interne présente un cube qui d'aspect extérieur semble être composé d'un grand cube formé lui-même de 27 petits cubes. Chaque face du grand cube, qui présente à l'origine des couleurs différentes, peut indépendamment pivoter autour de son axe central d'un ou plusieurs quarts de tour, créant ainsi pour chaque face du grand cube un mélange de couleurs provenant des différences de couleurs des faces des petits cubes. Une fois le grand cube manipulé et mélangé, le jeu consiste soit par tâtonnement soit par la recherche d'algorithmes reconstituer les couleurs d'origine des faces du grand cube.We know above all the game Rubik's Cube® which by an internal mechanism has a cube that looks outside appear to be composed of a large cube formed itself 27 small cubes. Each face of the large cube, which originally has different colors, can independently rotate around its central axis one or more quarters of a turn, creating for each face of the large cube a mixture of colors from color differences faces of small cubes. Once the big cube is manipulated and mixed, the game consists of either trial and error or the search for algorithms restore the original colors of the faces of the big cube.

Le document WO 2004/088 615 A décrit un jeu selon le préambule de la revendication 1.The document WO 2004/088615 A describes a game according to the preamble of claim 1.

La présente invention propose un jeu, composé de petits cubes élémentaires superposables et juxtaposables, tel que défini en revendication 1 annexée.The present invention provides a set consisting of small stackable elementary cubes and juxtaposable, as defined in appended claim 1.

Par ailleurs selon d'autres caractéristiques avantageuses de l'invention :

  • les facettes du premier et du second groupe sont respectivement de polarités opposées :
  • tous les éléments magnétiques associés à l'un au moins des groupes de facettes sont formés d'aimants permanents ;
  • certaines au moins des paires de 2 cubes élémentaires adjacents comprennent des empreintes en creux et/ou empreintes en saillie respectivement complémentaires sur leurs faces adjacentes ;
  • les faces affleurées par les facettes d'un même groupe possèdent des empreintes en saillie et/ou en creux et que les faces affleurées par les facettes de l'autre groupe possèdent les empreintes complémentaires ;
  • certaines faces au moins de certains cubes élémentaires possèdent des éléments en saillie de symétrie de révolution complémentaires de cuvettes disposées sur les faces adjacentes permettant un guidage de rotation relative de sous-ensembles du jeu ;
  • dans leur position d'origine et prises isolément, les faces soit dans l'ensemble des faces visibles, soit dans l'ensemble des faces non visibles ou soit enfin dans l'ensemble des faces neutres, ont soit une même couleur soit une couleur fonction de leur orientation.
Moreover according to other advantageous features of the invention:
  • the facets of the first and the second group are respectively of opposite polarities:
  • all the magnetic elements associated with at least one of the groups of facets are formed of permanent magnets;
  • at least some of the pairs of two adjacent elementary cubes comprise indentations and / or indentations projecting complementary respectively on their adjacent faces;
  • the faces flush with the facets of the same group have indentations and / or indentations and that the faces flush with the facets of the other group have the complementary imprints;
  • at least some of the faces of certain elementary cubes have complementary projection symmetry elements of cups disposed on the adjacent faces, allowing relative rotation guidance of subsets of the game;
  • in their original position and taken in isolation, the faces either in the set of visible faces, or in the set of non-visible faces or finally in the set of neutral faces, have either the same color or a color function of their orientation.

Dans un mode de réalisation souhaité de l'invention proche du Rubik's Cube®, la présente invention se distingue par le fait que les petits cubes, dans ce mode au nombre de 27, sont groupés géométriquement en un seul grand cube et liés magnétiquement mais peuvent être séparés les uns des autres. Les faces en plus de leur possibilité de rotation autour de leur axe peuvent être séparées et remises en place après renversement. Un tel dispositif présente par rapport au Rubik's Cube® le double avantage de pouvoir reconstituer à tout moment le jeu dans sa position initiale si le joueur le désire et d'augmenter le champ de mouvements, donc la complexité du puzzle en y ajoutant une autre dimension.In a preferred embodiment of the invention close to the Rubik's Cube®, the present invention is distinguished by the fact that the small cubes, in this mode numbering 27, are geometrically grouped in a single large cube and magnetically bonded but can to be separated from each other. The faces in addition to their possibility of rotation about their axis can be separated and put back in place after overturning. Such a device has in comparison with the Rubik's Cube® the double advantage of being able to reconstitute at any moment the game in its initial position if the player wishes it and to increase the field of movements, therefore the complexity of the puzzle by adding another dimension .

La présente invention est relative à un volume constitué de cubes élémentaires assemblés magnétiquement et géométriquement.The present invention relates to a volume consisting of elementary cubes assembled magnetically and geometrically.

Dans ce document on entend par "cube élémentaire" ou encore "petit cube" tout polyèdre ou volume possédant au moins six faces planes telles que les plans qu'elles définissent partitionnent géométriquement l'espace en un ensemble de partitions volumique dont une est un cube de volume fini. Dans ce document ces six faces sont désignées comme lesdites faces dudit cube élémentaire. Par exemple un cube dont on aurait tronqué partiellement ou totalement les arêtes constitue un dit cube élémentaire dont les six dites faces sont ce qu'il reste des faces du cube initial.In this document we mean by "elementary cube" or "small cube" any polyhedron or volume having at least six planar faces such that the plans they define geometrically partition the space into a set of voluminal partitions of which one is a cube of finished volume. In this document these six faces are designated as said faces of said elementary cube. For example, a cube whose edges have been partially or totally truncated constitutes an elementary cube whose six faces are what are left of the faces of the initial cube.

Les dites faces d'un cube élémentaire sont distinguées suivant les catégories suivantes :

  • Toutes lesdites faces desdits cubes élémentaires qui sont visibles lorsque ces cubes sont assemblés dans la configuration initiale du volume sont des faces dites visibles.
  • Toutes lesdites faces desdits cubes élémentaires opposées aux faces dites visibles sont des faces dites non visibles.
  • Toutes les dites faces restantes desdits cubes élémentaires sont des faces dites cachées ou neutres.
The said faces of an elementary cube are distinguished according to the following categories:
  • All said faces of said elementary cubes which are visible when these cubes are assembled in the initial configuration of the volume are so-called visible faces.
  • All said faces of said elementary cubes opposite the so-called visible faces are so-called non-visible faces.
  • All said remaining faces of said elementary cubes are so-called hidden or neutral faces.

Tous les cubes élémentaires sont constitués principalement de matières inertes d'un point de vue magnétique. Les matières inertes d'un point de vue magnétique sont les matières qui ne modifient pas un champ magnétique environnant. On définit pour l'ensemble de ce document le terme de "matière non conductrice" comme étant de la matière inerte d'un point de vue magnétique. Des exemples de matières non conductrices sont les matières plastiques, le bois ou des matières analogues.All elementary cubes are mainly made of inert materials from a magnetic point of view. Magnetically inert materials are those materials that do not alter a surrounding magnetic field. For the purposes of this document, the term "non-conductive material" is defined as being inert from a magnetic point of view. Examples of non-conductive materials are plastics, wood or the like.

Tous les cubes possèdent tous au centre de leurs six faces, un élément magnétique, de préférence en forme d'un disque cylindrique et plat (9) ou en forme cylindro-conique (16), dont une des facettes affleure globalement la face du cube élémentaire. On entend par "affleurer globalement" ou tout simplement "affleurer" tout type de disposition d'élément magnétique à l'intérieur d'un cube élémentaire dont une des facettes est placée suffisamment proche de la surface extérieure de ce cube pour pouvoir interagir magnétiquement avec une pièce située à l'extérieur du volume de ce cube élémentaire. Ainsi la facette d'un élément magnétique sous une peau ou une certaine épaisseur d'une face extérieure d'un cube élémentaire est globalement affleurant tant qu'elle peut interagir magnétiquement à l'extérieur du volume délimité par ce cube.All the cubes all have in the center of their six faces, a magnetic element, preferably in the form of a cylindrical disk and flat (9) or cylindro-conical (16), one of the facets is generally flush with the face of the cube elementary. The term "flush globally" or simply "flush" any type of magnetic element layout within an elementary cube which one of the facets is placed sufficiently close to the outer surface of the cube to be able to interact magnetically with a room located outside the volume of this elementary cube. Thus the facet of a magnetic element under a skin or a certain thickness of an outer face of an elementary cube is generally flush as long as it can interact magnetically outside the volume defined by this cube.

Par la suite on assimilera la polarité d'une face d'un cube élémentaire à la polarité de la facette de l'élément magnétique globalement affleurant et sous-jacent. On assimilera aussi la qualité visible, non visible ou neutre d'une facette d'un élément magnétique respectivement aux qualités : visible, non visible, et neutre de la face affleurée par la facette de l'élément magnétique.Subsequently we will assimilate the polarity of a face of an elementary cube to the polarity of the facet of the generally flush and underlying magnetic element. We will also assimilate the visible quality, not visible or neutral of a facet of a magnetic element respectively to the qualities: visible, non-visible, and neutral of the face flush with the facet of the magnetic element.

L'homme du métier comprendra qu'un tel petit cube puisse être constitué par l'assemblage de six semelles pyramidales tronquées à base carrée (10) possédant en leur centre une cavité circulaire (11) ayant, soit un fond de faible épaisseur (19), soit sans fond avec une collerette circulaire comme un siège de soupape (18), adaptée pour y insérer ou y loger un élément magnétique adéquat : les six semelles étant, soit collées entre elles et sur les six faces d'un noyau cubique (17), éventuellement clippées entre elles ou sur un noyau ayant une forme adéquate.Those skilled in the art will understand that such a small cube can be constituted by the assembly of six truncated pyramidal treads with a square base (10) having in their center a circular cavity (11) having either a thin bottom (19). ), either bottomless with a circular collar such as a valve seat (18), adapted to insert or accommodate a suitable magnetic element therein: the six soles being either glued together and on the six faces of a cubic core ( 17), possibly clipped together or on a core having a suitable shape.

L'ensemble des facettes dites visibles et des facettes dites non visibles constitue un premier groupe de facettes. Autrement dit ce premier groupe de facettes est composé des facettes des éléments magnétiques affleurant les faces visibles (6) et non visibles (7) des cubes élémentaires.The set of so-called visible facets and so-called non-visible facets constitutes a first group of facets. In other words, this first group of facets is composed of the facets of the magnetic elements flush with the visible (6) and non-visible faces (7) of the elementary cubes.

L'ensemble des facettes dites neutres constitue un second groupe de facettes. Autrement dit ce second groupe de facettes est composé des facettes des éléments magnétiques affleurant les faces neutres (8), complémentaires des faces visibles (6) et non visibles (7) des cubes élémentaires.The set of so-called neutral facets constitutes a second group of facets. In other words, this second group of facets is composed of the facets of the magnetic elements flush with the neutral faces (8), complementary to the visible (6) and non-visible faces (7) of the elementary cubes.

L'invention est caractérisée en ce que l'ensemble des facettes de l'un au moins des deux groupes est de même polarité.The invention is characterized in that all the facets of at least one of the two groups are of the same polarity.

Un mode préféré de réalisation de l'invention est représenté en figure.1 sous la forme d'un grand cube (1) composé de cubes élémentaires que l'on placera à des fins de compréhension dans un système orthonormé dont le centre sera le centre du cube avec les trois axes OX,OY,OZ perpendiculaires respectivement aux faces principales du cube.A preferred embodiment of the invention is shown in figure 1 in the form of a large cube (1) composed of elementary cubes that will be placed for of understanding in an orthonormal system whose center will be the center of the cube with the three axes OX, OY, OZ perpendicular respectively to the main faces of the cube.

Ce grand cube peut être avantageusement constitué de 27 cubes élémentaires. Chaque face du grand cube est alors constituée de 9 cubes formant par exemple des lignes de trois cubes accolés les uns aux autres sur trois rangées. Tous ces éléments une fois assemblés forment un grand cube.This large cube may advantageously consist of 27 elementary cubes. Each face of the large cube is then made of 9 cubes forming for example lines of three cubes contiguous to each other in three rows. All these elements once assembled form a large cube.

Une fois les petits cubes regroupés, le grand cube se trouve être constitué de 27 petits cubes comprenant :

  • 8 petits cubes d'angle (2) ayant chacun trois faces extérieures ou visibles (6) et 3 autres faces dites non visibles (7) directement opposées aux faces visibles.
  • 12 petits cubes d'arête (3) avec chacun deux faces visibles (6) , 2 autres faces dites non visibles (7) directement opposées aux faces visibles ainsi que deux autres faces dites neutres ou cachées (8).
  • 6 petits cubes centre-face (4) avec chacun une seule face visible (6) et une autre face dite non visible (7) directement opposée à la face visible ainsi que 4 autres faces dites neutres ou cachées (8) .
  • 1 petit cube centre-cube ou noyau (5) avec aucune face visible ni non visible et possédant donc six faces dites neutres ou cachées (8).
Once the small cubes are grouped together, the big cube is made up of 27 small cubes including:
  • 8 small angle cubes (2) each having three outer or visible faces (6) and 3 other so-called non-visible faces (7) directly opposite to the visible faces.
  • 12 small edge cubes (3) each with two visible faces (6), 2 other so-called non-visible faces (7) directly opposite to the visible faces and two other so-called neutral or hidden faces (8).
  • 6 small center-facing cubes (4) each with a single visible face (6) and another non-visible face (7) directly opposite to the visible face and 4 other faces said neutral or hidden (8).
  • 1 small cube center cube or core (5) with no visible or non-visible face and thus having six so-called neutral or hidden faces (8).

On comprendra aisément que pour maintenir solidement le groupe de petits cubes il est indispensable que les faces des petits cubes qui sont en contact entre elles aient des polarités opposées de façon à créer une attraction magnétique au niveau des faces des petits cubes qui sont mutuellement en contact : des polarités identiques entraîneraient une répulsion entre faces. Cette condition de liaison magnétique entre toutes les faces des petits cubes en contact est obtenue en appliquant l'invention.It will be easily understood that in order to firmly hold the group of small cubes it is essential that the faces of the small cubes which are in contact with each other have opposite polarities so as to create a Magnetic attraction at the faces of small cubes which are in contact with each other: identical polarities would cause repulsion between faces. This condition of magnetic connection between all the faces of the small cubes in contact is obtained by applying the invention.

Les éléments magnétiques peuvent être pour partie des aimants. Les facettes de ces éléments magnétiques appartenant aux différents groupes de facettes sont alors des pôles de ces aimants, au moins un des groupes de facettes étant de même polarité.The magnetic elements may be partly magnets. The facets of these magnetic elements belonging to the different groups of facets are then poles of these magnets, at least one of the groups of facets being of the same polarity.

Les autres éléments magnétiques n'étant pas des aimants peuvent alors être des pièces ferromagnétiques par exemple des disques en fer doux de diamètre et d'épaisseur appropriés sans trop réduire les forces de cohésion magnétiques qui maintiennent les petits cubes entre eux.The other magnetic elements that are not magnets can then be ferromagnetic parts, for example soft iron disks of appropriate diameter and thickness without reducing the magnetic cohesive forces that keep the small cubes together.

Dans un mode de réalisation privilégié, la totalité des éléments magnétiques peuvent être des aimants. Dans ce mode de réalisation, les pôles du premier groupe de facettes sont tous d'une même polarité et les pôles du second groupe de facettes sont tous de la polarité opposée.In a preferred embodiment, all of the magnetic elements may be magnets. In this embodiment, the poles of the first group of facets are all of the same polarity and the poles of the second group of facets are all of the opposite polarity.

Comme le montre la figure.14, on peut considérer que le grand cube (1) est constitué de trois tranches parallèles (20) (23) et (20) perpendiculaires à l'axe OX. Chaque tranche est formée de neuf petits cubes groupés trois par trois et situés dans un même plan. Les tranches extérieures (20) peuvent être considérées comme des faces du grand cube. Il en est de même pour les tranches (21) et (22) suivant les axes OZ et OY. On voit donc que l'on peut virtuellement détacher six tranches distinctes (ou une face du grand cube) du reste du cube.As shown in figure.14 it can be considered that the large cube (1) consists of three parallel slices (20) (23) and (20) perpendicular to the axis OX. Each slice consists of nine small cubes grouped three by three and located in the same plane. The outer slices (20) can be considered as faces of the large cube. It is the same for the slices (21) and (22) along the axes OZ and OY. So we see that we can virtually detach six distinct slices (or one face of the big cube) from the rest of the cube.

Comme le montre la figure.22, pour détacher physiquement une face du reste du cube il faut tenir et recouvrir d'une main deux tranches inférieures (24) du grand cube et de l'autre main faire pivoter (r) la tranche restante (20) autour de son axe principal OY perpendiculaire à la face de façon à échapper aux liaisons magnétiques des 8 éléments magnétiques périphériques. Une fois ce pivotement effectué on peut séparer pratiquement sans effort (figure.23) la tranche (20) du reste du cube (24) par un soulèvement vertical (t).As shown in figure.22 to physically detach a face from the rest of the cube, two lower slices (24) of the large cube must be held and covered with one hand and the remaining slice (20) rotated around its main axis (r) OY perpendicular to the face so as to escape the magnetic bonds of the 8 peripheral magnetic elements. Once this pivoting is done, it is possible to separate practically without effort ( figure.23 ) the wafer (20) of the rest of the cube (24) by a vertical lift (t).

Comme la tranche ou face détachée (20) présente trois plans de symétrie distincts XOY,ZOY,XOZ la remise en place de cette tranche sur sa base (24) peut se réaliser de 2x2x2=8 manières différentes : par exemple, en faisant autour de l'axe OY une ou plusieurs rotations par quart de tour, suivi ou pas d'un renversement de la tranche sur elle-même, renversement qui correspond à une rotation de 180° par rapport à l'axe OX ou OY de la dite tranche.As the slice or detached face (20) has three distinct planes of symmetry XOY, ZOY, XOZ the replacement of this slice on its base (24) can be made of 2x2x2 = 8 different ways: for example, by making around the axis OY one or more rotations per quarter turn, followed or not a reversal of the wafer on itself, reversal which corresponds to a rotation of 180 ° with respect to the axis OX or OY of said slice .

L'homme du métier notera que la tranche (20), une fois détachée, a toutes les faces visibles de ses petits cubes de même polarité (+) qui sont avant la séparation les faces visibles ou non visibles de petits cubes. De même la face découverte du grand cube restant a toutes les faces des petits cubes de polarité inverse (-) puisque, ne provenant pas de faces dites visibles ou dites non visibles, elles sont neutres ou cachées (8). Il s'en suit que quelque soit le mouvement subi par la tranche (rotation ou renversement) sa remise en place sur sa base maintient la totalité des liaisons magnétiques à l'intérieur du grand cube.Those skilled in the art will note that the slice (20), once detached, has all the visible faces of its small cubes of the same polarity (+) which are before the separation the visible or non-visible faces of small cubes. Similarly, the uncovered face of the large cube remaining on all sides of small cubes of inverse polarity (-) since, not coming from so-called visible faces or said not visible, they are neutral or hidden (8). It follows that regardless of the movement undergone by the slice (rotation or overturning) its restoration on its base maintains all the magnetic bonds inside the big cube.

L'homme du métier notera aussi que quelques soient les mouvements aléatoires imposés aux diverses tranches du grand cube les cubes d'angle restent des cubes d'angle. Il en est de même pour les cubes d'arêtes et les cubes de centre face.Those skilled in the art will also note that, whatever the random movements imposed on the various slices of the large cube, the angle cubes remain cubes of angle. It is the same for the cubes of edges and the cubes of center face.

Dans un mode préféré de réalisation, afin d'assurer une parfaite rotation des tranches (20,21,22), le cube central (5) du grand cube (1) ou noyau du grand cube peut être pourvu sur chacune de ses 6 faces d'éléments en saillie de symétrie de révolution, par exemple un tourillon (13), de préférence de faible longueur, comme l'indique la figure.11. Pour assurer la compatibilité avec le tourillon des noyaux, les cubes centre face (4) possèdent préférentiellement sur leur face visible et leur face non visible, une cuvette en creux (12) de forme complémentaire aux éléments en saillie du noyau (13). Les faces des petits cubes pourvues de cuvettes ou de tourillons peuvent garder le même type d'affleurement des aimants que les autres faces. Cependant on peut aussi aisément garder la cohérence du grand cube en supprimant les aimants de ces faces.In a preferred embodiment, to ensure a perfect rotation of the slices (20,21,22), the central cube (5) of the large cube (1) or core of the large cube can be provided on each of its six faces protruding elements of symmetry of revolution, for example a trunnion (13), preferably of short length, as indicated by figure.11 . To ensure compatibility with the journal of the cores, the center-facing cubes (4) preferably have on their visible face and their non-visible face, a hollow bowl (12) of complementary shape to the projecting elements of the core (13). The faces of the small cubes provided with bowls or trunnions may keep the same type of outcropping magnets as the other faces. However one can also easily keep the coherence of the big cube by removing the magnets of these faces.

Bien évidemment l'utilisation sur des faces de cubes élémentaires d'éléments en saillie ayant une symétrie de révolution avec sur les faces adjacentes des cuvettes complémentaires à ces éléments s'étend à tous les modes de réalisation de la présente invention. Ces éléments permettent le guidage de rotation relative de sous-ensembles du jeu.Of course, the use on surfaces of elementary cubes of protruding elements having a symmetry of revolution with on the adjacent faces cuvettes complementary to these elements extends to all the embodiments of the present invention. These elements allow the relative rotation guidance of subsets of the game.

Dans un autre mode préféré de réalisation, on peut assurer un bon repositionnement des tranches ou un parfait blocage mécanique de l'ensemble des petits cubes entre eux. Les faces affleurées par des facettes du premier groupe de facettes peuvent alors en partie ou en totalité présentées une même empreinte en saillie et/ou en creux (14) respectant de préférence la symétrie des cubes élémentaires. Les faces affleurées par des facettes du second groupe de facettes présentant alors, pour leur ensemble ou en partie, l'empreinte en creux et/ou en saillie complémentaire (15), ce système assure un blocage mécanique des cubes entre eux améliorant la tenue et la rigidité de l'ensemble.In another preferred embodiment, it is possible to ensure a good repositioning of the slices or a perfect mechanical blocking of all the small cubes between them. Faces flush with facets first group of facets may then in part or in whole presented the same projecting and / or hollow recess (14) preferably respecting the symmetry of the elementary cubes. The faces flush with facets of the second group of facets then having, in whole or in part, the indentation and / or complementary projection (15), this system provides a mechanical blocking cubes between them improving the holding and the rigidity of the whole.

Ce dernier mode de réalisation peut aussi s'appliquer en complément du mode de réalisation précédent. Ainsi toutes les faces ne possédant pas de tourillons ou de cuvettes peuvent accueillir l'empreinte en creux et/ou en saillie (14) ou l'empreinte complémentaire (15) suivant la polarité de sa face.This last embodiment can also be applied in addition to the previous embodiment. Thus all the faces having no trunnions or cuvettes can accommodate the indentation and / or projection (14) or the complementary imprint (15) according to the polarity of its face.

Enfin ce dernier mode de réalisation s'applique aussi dans le cas le plus général de l'invention. Les faces affleurées par des facettes du même groupe peuvent alors présenter une même empreinte et les faces affleurées par des facettes de l'autre groupe peuvent présenter l'empreinte complémentaire. On peut voir qu'il n'est pas nécessaire que toutes les faces possèdent une empreinte.Finally, this last embodiment also applies in the most general case of the invention. The faces flush with facets of the same group may then have the same fingerprint and the flush faces by facets of the other group may have the complementary fingerprint. It can be seen that it is not necessary for all faces to have an imprint.

Dans tous les modes de réalisations permis par l'invention, on peut rajouter des marquages de couleurs sur les différentes faces des cubes élémentaires, visibles, non visibles et même neutres, permettant de constituer un puzzle dont la configuration d'origine est la configuration que l'on cherche à obtenir après un mélange des différents cubes élémentaires par rotation ou retournement des sous ensembles. Pour prendre un exemple, on peut visualiser le mode de réalisation de l'invention en forme de Rubik's Cube® avec des autocollants de couleurs sur les faces des cubes élémentaires.In all the embodiments enabled by the invention, it is possible to add color markings on the different faces of the elementary cubes, visible, non-visible and even neutral, making it possible to constitute a puzzle whose original configuration is the configuration that we seek to obtain after a mixture of the different elementary cubes by rotation or inversion subsets. To take an example, one can visualize the embodiment of the invention shaped Rubik's Cube® with colored stickers on the faces of the elementary cubes.

Dans ce dernier mode les faces des cubes élémentaires ont une couleur qui est fonction de l'orientation des faces dans la configuration initiale. Cette caractéristique peut s'appliquer bien évidemment à tous les modes de réalisation de l'invention.In the latter mode the faces of the elementary cubes have a color that is a function of the orientation of the faces in the initial configuration. This characteristic can obviously apply to all the embodiments of the invention.

D'autres modes de marquages couleurs sont encore réalisables permettant la création de puzzles originaux.Other modes of color markings are still feasible allowing the creation of original puzzles.

On peut tout d'abord complexifier le marquage couleur de type Rubik's Cube® en attribuant une couleur à une face non seulement en fonction de son orientation mais aussi en fonction de son caractère visible ou non visible ou même neutre.Rubik's Cube® color marking can first be complicated by attributing a color to a face not only according to its orientation but also according to its visible or non-visible or even neutral character.

On peut aussi simplement donner une couleur à toutes les faces visibles et une autre à toutes les faces non visibles. On obtient alors, dans le cas du grand cube de 27 petits cubes élémentaires, dans la configuration initiale un grand cube entièrement noir que l'on peut à l'aide des différentes manipulations rendre entièrement blanc.We can also simply give a color to all visible faces and another to all non-visible faces. In the case of the large cube of 27 small elementary cubes, in the initial configuration, we obtain a large, entirely black cube that can be made entirely white using the various manipulations.

L'utilisation des marquages couleurs pour les faces de cubes élémentaires n'est bien évidemment pas limitée au mode de réalisation de l'invention sous la forme proche d'un Rubik's Cube® mais s'étend à la généralité du jeu que revendique l'invention.The use of color markings for the faces of elementary cubes is obviously not limited to the embodiment of the invention in the form of a Rubik's Cube® but extends to the generality of the game claimed by the invention.

De même les marquages couleurs peuvent aisément être remplacés par des petites images ou photographies sur une partie ou la totalité des faces de cubes élémentaires créant un jeu comparable à un puzzle de dimension supérieure à 2.In the same way the color markings can easily be replaced by small images or photographs on some or all the faces of elementary cubes creating a game comparable to a puzzle of dimension superior to 2.

Enfin il bien évident que l'invention s'étend aussi aux modes de réalisation où les marquages de couleurs ne sont pas réalisés par des éléments disposés sur les faces des cubes élémentaires mais directement par la matière des faces de cubes élémentaires.Finally, it is obvious that the invention also extends to the embodiments where the color markings are not made by elements arranged on the faces. elementary cubes but directly by the material of the faces of elementary cubes.
