A sheet of material formed for folding into a three-dimensional structure. The sheet has edges formed with joinder structures, such as dovetails, and a plurality of folding structures, such as slits, grooves or displacements, that control folding of the sheet in a manner causing the joinder structures to be folded into interlocking interengagement. The folding structures are configured for very precise folding of the sheet so that the folding structures will be in precise registered juxtaposition. Additionally, the sheet of material includes a retention structure, such as a retention fold or a retention deformation, which will prevent unfolding of the sheet. A method for fastener-free joining of sheet edges together also is disclosed, as are the resulting three-dimensional structures.
La présente invention a trait à une feuille de matériau conformé pour le pliage en une structure tridimensionnelle. La feuille comporte des bords formés avec des structures de jonction, telles que des queues d'arondes, et une pluralité de structures de pliage, telles que des fentes, rainures ou entailles, qui contrôlent le pliage de la feuille de manière à entraîner le pliage des structures de jonction dans un engagement mutuel de blocage. Les structures de pliage sont conformées pour un pliage très précis de la feuille de sorte que les structures de pliages vont se trouver en juxtaposition calée précise. En outre, la feuille de matériau comporte une structure de retenue, telle qu'un pli de retenue ou une déformation de retenue, qui va interdire le dépliage de la feuille. L'invention a également trait à un procédé pour la jonction sans attache de bords de feuille, ainsi qu'aux structures tridimensionnelles obtenues.
