Abstract

L'invention fournit un dispositif antichute qui peut être manipulé, notamment transporté, aisément. Ce dispositif antichute (10) est équipé d'un amortisseur (20), d'une première partie base (30), d'une seconde partie base (40) et d'un outil de raccordement (70). Le dispositif antichute (10) est installé entre une face supérieure d'un meuble (1) disposé sur le sol, et un plafond (C), et une force d'expansion d'un gaz comprimé renfermé dans un cylindre (21), est conférée dans une direction d'extension de longueur. La première partie base (30) est raccordée à une partie extrémité de l'amortisseur (20) de manière à permettre une rotation libre, et possède une première face de contact (31A) qui vient en contact avec la face supérieure du meuble (1). La seconde partie base (40) est raccordée à l'autre partie extrémité de l'amortisseur (20) de manière à permettre une rotation libre, et possède une seconde face de contact (41A) qui vient en contact avec le plafond (C). L'outil de raccordement (70) rétracte l'amortisseur (20), et le maintient dans un état de rétractation tel que la première partie base (30) et la seconde partie base (40) sont rapprochées.
