Abstract
Description
L'invention concerne, de façon générale, le domaine des jouets éducatifs et d'éveil.The invention relates generally to the field of educational and waking toys.
Plus précisément, l'invention concerne un jeu d'assemblage comportant au moins une vis, un écrou, et un ensemble de modules, chaque vis présentant une tête et un fût fileté propre à recevoir un écrou muni d'un taraudage, chaque écrou comportant une butée prolongée par un manchon, et chaque module présentant au moins un orifice d'assemblage permettant l'introduction d'une vis destinée à l'assembler à au moins un autre module pour former un empilement défini entre la tête de cette vis et l'écrou, une fois cet écrou engagé sur le fût de cette vis.More specifically, the invention relates to an assembly set comprising at least one screw, a nut, and a set of modules, each screw having a head and a threaded shaft adapted to receive a nut provided with a thread, each nut comprising a stop extended by a sleeve, and each module having at least one assembly opening allowing the introduction of a screw for assembling it to at least one other module to form a stack defined between the head of this screw and the nut, once this nut engaged on the barrel of this screw.
Bien que beaucoup de jeux de ce type soient connus depuis longtemps comme le montre notamment le
L'invention a au contraire pour but de proposer un jeu d'assemblage simple, bien adapté aux jeunes et très jeunes enfants.The invention instead aims to provide a simple assembly game, well suited to young and very young children.
A cette fin, le jeu de l'invention, par ailleurs conforme à la définition générique qu'en donne le préambule ci-dessus, est essentiellement caractérisé en ce que le manchon de chaque écrou présente, à l'opposé de la butée, au moins un premier bourrelet périphérique externe élastique, en ce que chaque orifice d'assemblage de chaque module est dimensionné pour recevoir le manchon de l'écrou, et en ce que le premier bourrelet, après introduction du manchon de l'écrou dans les orifices alignés d'un empilement au moins formé d'un premier et d'un dernier modules, borde l'orifice d'assemblage du dernier module en adoptant une configuration d'expansion radiale, et comprime axialement cet empilement pour en maintenir la cohésion avant même l'introduction de la vis dans l'écrou, ce jeu étant destiné aux jeunes enfants.To this end, the set of the invention, moreover in accordance with the generic definition given in the preamble above, is essentially characterized in that the sleeve of each nut has, opposite the stop, the less a first elastic outer peripheral bead, in that each assembly opening of each module is sized to receive the sleeve of the nut, and in that the first bead, after insertion of the sleeve of the nut into the aligned orifices stacking less formed of a first and a last modules, borders the assembly hole of the last module by adopting a radial expansion configuration, and axially compresses the stack to maintain cohesion even before the introduction of the screw in the nut, this game is intended for young children.
Grâce à cet agencement, le jeune enfant peut réaliser un assemblage en n'ayant en mains, à chaque instant du montage, qu'au maximum deux éléments de l'assemblage final.Thanks to this arrangement, the young child can achieve an assembly by having in hand, at each moment of the assembly, that a maximum of two elements of the final assembly.
De préférence, chaque orifice d'assemblage de chaque module comprend au moins un lamage dimensionné pour recevoir la butée de l'écrou, ce lamage bordant cet orifice d'assemblage et bloquant en rotation la butée de l'écrou qui y est engagée.Preferably, each assembly orifice of each module comprises at least one counterbore dimensioned to receive the abutment of the nut, this countersink bordering this assembly hole and blocking in rotation the abutment of the nut engaged thereto.
La butée et le manchon de l'écrou sont très avantageusement réalisés dans un matériau élastiquement déformable, le taraudage de l'écrou étant alors formé par un insert rigide noyé au moins dans la butée de cet écrou.The abutment and the sleeve of the nut are very advantageously made of an elastically deformable material, the tapping of the nut then being formed by a rigid insert embedded at least in the abutment of this nut.
Le manchon de l'écrou et l'épaisseur des modules peuvent en outre être dimensionnés de manière que la vis, une fois serrée sur l'écrou, s'appuie sur le manchon de cet écrou en comprimant axialement et en dilatant radialement le premier bourrelet périphérique, sans s'appuyer directement sur l'empilement de modules, cette disposition permettant d'éviter le serrage ou le desserrage intempestifs de la vis par pivotement relatif des modules assemblés.The sleeve of the nut and the thickness of the modules may also be dimensioned so that the screw, once tightened on the nut, rests on the sleeve of this nut by compressing axially and radially expanding the first bead. peripheral, without relying directly on the stack of modules, this arrangement to prevent the inadvertent tightening or loosening of the screw by relative pivoting of the assembled modules.
Il peut en outre être judicieux de prévoir que le manchon de l'écrou présente, à proximité de la butée, au moins un second bourrelet périphérique externe élastique, et que ce second bourrelet, après introduction du manchon de l'écrou dans l'orifice d'assemblage d'un module, borde cet orifice d'assemblage en adoptant une configuration d'expansion radiale.It may also be wise to provide that the sleeve of the nut has, near the stop, at least a second elastic outer peripheral bead, and that the second bead, after insertion of the sleeve of the nut into the assembly port of a module, borders this assembly hole by adopting a radial expansion configuration.
Chaque module peut présenter au moins deux orifices d'assemblage et le manchon de l'écrou et l'épaisseur des modules peuvent être dimensionnés pour former des empilements de deux modules.Each module may have at least two assembly orifices and the sleeve of the nut and the thickness of the modules may be sized to form stacks of two modules.

Comme annoncé précédemment, l'invention concerne un jeu d'assemblage du type de ceux qui comprennent notamment des vis telles que la vis 1, des écrous tels que l'écrou 2, et des modules tels que les modules 3 et 4.As previously announced, the invention relates to a set of assemblies of the type including those including screws such as the
Chaque écrou est muni d'un taraudage 22, et chaque vis 1 présente une tête 10 et un fût fileté 11 propre à recevoir le taraudage 22 d'un écrou 2.Each nut is provided with a tapping 22, and each
Chacun des modules tels que 3 et 4 présente un ou plusieurs orifices d'assemblage, par exemple deux orifices tels que 31 et 32 pour le module 3, et 41, 42 pour le module 4.Each of the modules such as 3 and 4 has one or more assembly orifices, for example two orifices such as 31 and 32 for the
Chaque orifice tel que 31 permet l'introduction d'une vis 1 qui permet d'assembler le module 3 correspondant à par exemple un autre module 4, et de former ainsi un empilement de ces modules après engagement d'un écrou 2 sur le fût 11 de cette vis 1.Each orifice such as 31 allows the introduction of a
Selon l'invention, chaque écrou 2 comporte une butée 20 prolongée par un manchon 21, ce manchon présentant un ou plusieurs bourrelets périphériques externes élastiques, par exemple 211 et 212. Le premier bourrelet 211 est formé à distance de la butée 20, tandis que le deuxième bourrelet 212 est formé à proximité de cette butée.According to the invention, each
Par ailleurs, les orifices d'assemblage, tels que 31, 32 et 41, 42, sont dimensionnés pour recevoir sans jeu le manchon 21 d'un écrou 2.Moreover, the assembly orifices, such as 31, 32 and 41, 42, are dimensioned to receive without play the
Les
Dans cet exemple, et de façon chronologique, le manchon 21 de l'écrou 2 est d'abord introduit dans l'orifice 31 du module 3 jusqu'à ce que la butée 20 s'inscrive dans le lamage 500 bordant la partie inférieure de l'orifice 31.In this example, and chronologically, the
Pendant cette opération, le bourrelet 212 est comprimé radialement lors du passage à travers l'orifice 31, cette déformation étant par exemple rendue possible en réalisant le manchon creux 21 de l'écrou 2 dans un matériau élastiquement déformable.During this operation, the
A la fin de cette première opération, le bourrelet 212, qui a repris sa forme originelle, borde la partie supérieure de l'orifice 31 en adoptant sa configuration d'expansion radiale maximale et reste solidaire du module 3, de sorte que ce module et l'écrou 2 ne forment ensemble qu'une seule et même pièce.At the end of this first operation, the
Après alignement de l'orifice 41 du module 4 avec l'orifice 31 du module 3, le manchon 21 de l'écrou 2, lié au module 3, est alors introduit dans cet orifice 41.After alignment of the
Pendant cette opération, le bourrelet 211 est comprimé radialement lors du passage à travers l'orifice 41, cette déformation étant à nouveau rendue possible grâce par exemple à l'élasticité du manchon creux 21 de l'écrou 2.During this operation, the
A la fin de cette deuxième première opération, le bourrelet 211, qui a repris sa forme originelle, borde la partie supérieure de l'orifice 41 en adoptant sa configuration d'expansion radiale maximale, et reste solidaire du module 4, de sorte que l'écrou 2, le module 3, et ce module 4 ne forment ensemble qu'une seule et même pièce.At the end of this second first operation, the
Dans l'exemple illustré, le manchon 21 de l'écrou 2, l'épaisseur des lamages, et l'épaisseur E des modules 3 et 4 sont juste dimensionnés pour que le bourrelet 211 exerce une légère traction axiale sur le bord de l'orifice 41, donc une légère compression axiale sur l'empilement des deux modules 3 et 4, lorsque la butée 20 est en appui dans le fond du lamage 500 bordant l'orifice 31 à sa partie inférieure.In the illustrated example, the
La cohésion de l'empilement des modules 3 et 4 réalisé par l'écrou 2 étant ainsi assurée, l'enfant peut introduire la vis 1 dans l'écrou 2 et la serrer, toujours en ne tenant que deux pièces entre ses mains.The cohesion of the stack of
Lors du serrage de la vis 1 dans l'écrou 2, la base 100 de la tête 10 de cette vis vient porter sur l'extrémité 200 de l'écrou 2 sans toucher le module 4, c'est-à-dire sans appuyer directement sur l'empilement formé par les modules 3 et 4.When tightening the
Grâce à cet agencement, le pivotement relatif des modules 3 et 4 autour de l'axe de la vis 1 ne peut conduire ni à serrer cette vis, ni à la desserrer.Thanks to this arrangement, the relative pivoting of the
Une fois complètement serrée sur l'écrou 2, la vis 1, en s'appuyant sur l'extrémité 200 de l'écrou 2, comprime axialement le bourrelet périphérique 211 du manchon 21 et dilate radialement ce bourrelet, provoquant un serrage doux de l'empilement des modules 3 et 4.Once completely tightened on the
Comme le montrent les
Dans ce cas, le taraudage 22 de l'écrou 2 peut alors être formé par un insert rigide 221, par exemple en polypropylène, noyé dans l'épaisseur de la butée 20 de cet écrou.In this case, the
De même, la vis 1 peut être réalisée par un moulage bi-matière, et comprendre un noyau de polypropylène formant le fût 11 et une partie centrale de la tête 10, cette partie centrale étant recouverte d'un élastomère offrant un grand confort au toucher et du même type que celui utilisé pour réaliser le manchon 21 de l'écrou 2.Similarly, the
