Abstract

On cherche a rendre possible differentes formes d'execution en systeme modulaire pour la creation d'un programme de meubles a partir d'un meuble, par exemple a partir d'une chaise, en permettant de combiner des sieges et/ou des dossiers differents avec des pieds de longueurs differentes. Dans ce but les cadres (11), reliant entre eux les pieds. (10), sont faits en tubes metalliques et possedent des extremites elargies en trompette formees de facon complementaire a la forme du trace du pied de maniere telle qu'elles entourent une partie du pourtour du pied, ces cadres etant relies au pied de facon demontable au moyen d'une vis (17), s'etendant dans le prolongement du cadre et traversant le pied de part en part. L'ecrou correspondant (18) est, de preference, soude dans le cadre (11) tandis que la tete de la vis se trouve dans une encoche metallique (15), qui elle se trouve dans une gorge transversale (14) du pied, qui est de preference en bois, ladite encoche etant formee de maniere telle qu'elle ne depasse pas le pourtour du pied.
