Abstract

L'invention concerne un dispositif ménager comprenant une unité de fixation (12a-e), destinée à fixer au moins partiellement une unité plane (14a-e) à une unité de base (16a-b). Pour produire un dispositif générique présentant des propriétés améliorées en termes d'efficacité, il est proposé que l'unité de fixation (12a-e) permette, dans au moins un état assemblé, un mouvement limité d'au moins une partie de l'unité plane (14a-e) par rapport à l'unité de base (16a-b) dans une direction de déplacement (18a-b) au moins sensiblement parallèle à un plan d'extension principal de l'unité plane (14a-14a-e).
