Abstract

La présente invention concerne un dispositif charnière (103) qui comprend au moins une première unité de charnière (108) et une seconde unité de charnière (109). La première unité de charnière (108) comprend une partie de raccordement (115); la seconde unité de charnière (109) comprend une rainure de guidage (1131); la première unité de charnière (108) est reliée de manière coulissante à la rainure de guidage (1131) de la seconde unité de charnière (109) au moyen de la partie de raccordement (115). Par conséquent, le dispositif charnière est pratique pour un utilisateur pour une utilisation selon une préférence personnelle et un besoin de changer la forme d'un élément souple. La présente invention concerne en outre un ensemble pliable (100).
