Title
(EN) DAMPER FOR THE STILES OF A TELESCOPIC LADDER
(FR) AMORTISSEUR POUR MONTANTS D'UNE ÉCHELLE TÉLESCOPIQUE
Abstract
(EN)
A damper is disclosed for a ladder having telescopically collapsible stile sections. The damper operated pneumatically and comprises a plug 14 for closing off the lower end of an upper stile section 10 in each pair of adjacent stile sections, and a seal 22 projecting radially from the plug 14 so as to contact the inner wall of the lower stile section of the pair. During collapse of the stile sections of the pair, the upper style section acts as a piston to compress air present within the lower section.
(FR)
L'invention concerne un amortisseur destiné à une échelle comportant des sections de montant repliables de manière télescopique. L'amortisseur est actionné pneumatiquement et comprend un bouchon 14 permettant de fermer l'extrémité inférieure d'une section de montant supérieure 10 dans chaque paire de sections de montant adjacentes, et un joint d'étanchéité 22 faisant saillie radialement depuis le bouchon 14 de sorte à entrer en contact avec la paroi interne de la section de montant inférieure de la paire. Lors du repliement des sections de montant de la paire, la section de montant supérieure agit comme un piston pour comprimer l'air présent à l'intérieur de la section inférieure.
