CA 2209491

The set is essentially formed of parallelepipedic base pieces (1) with a perimetric groove in the edge thereof for inserting tongues (3) projecting from some of the edges. They are provided with at least one axial opening (4) which receives another piece embodied by a stepped cylindrical button (5) which may rotate in its housing due to the presence of four axial peripheral lugs (7) which are housed into an annular undercut (6) of the base piece (1), said undercut being concentric with respect to the opening. Both the annular undercuts (6) and the axial lugs (7) are provided on both sides of the piece. The cylindrical button (5) has a diametral groove (9) which is open at the periphery. Other triangular pieces (13, 14) are also provided by cutting diagonally the square base pieces (1), having protuberances (15) and recesses (16) for interconnection purposes. The set also includes hinge-type articulated pieces (17) of which the wings are similar to the square base pieces (1). There are also covers (19) which are nestable between each other and into the axial opening (4) by means of the annular undercut (6) of any other piece; there are also triangular covers (20) acting as half-elements. By using the base pieces (1) it is possible to form on a board mosaic drawings with the square (19) and triangular (20) covers.

L'ensemble est constitué essentiellement de pièces de base parallélépipédiques (1) présentant une rainure périmétrique en leur bord dans laquelle on peut introduire une languette (3) partant de certains des bords des pièces. Ces pièces présentent au moins un vide ou trou axial (4) recevant une autre pièce matérialisée par un bouton cylindrique étagé (5) qui peut tourner dans son logement à l'aide de quatre ergots axiaux périphériques (7) qui se logent dans une entaille annulaire (6) de la pièce de base (1), cette entaille étant concentrique au trou respectif. Tant les entailles annulaires (6) que les ergots axiaux (7) se trouvent sur les deux faces de la pièce. Le bouton cylindrique (5) possède une rainure diamétrale (9) ouverte à la périphérie. Il existe d'autres pièces triangulaires (13, 14) obtenues en coupant en diagonal les pièces de base carrées (1), et présentant elles aussi des protubérances (15) et des rentrants (16) pour assurer l'interconnexion. Des pièces articulées (17) de type charnière sont prévues, leurs ailes étant semblables aux pièces de base carrées (1). Des couvercles (19) emboîtables entre eux et dans le trou axial (4) au moyen de l'entaille annulaire (6) de n'importe quelle autre pièce sont également prévus; il existe aussi des couvercles triangulaires (1) jouant le rôle de demi-éléments. A l'aide de cet ensemble de pièces de base (1), il est possible de former sur une planche ou support similaire des dessins en mosaïque avec les couvercles carrés (19) et triangulaires (20).
