Title (EN) FIBERGLASS EXTENSION LADDER
(FR) ECHELLE A COULISSE EN FIBRE DE VERRE
Abstract:
(EN) An extension ladder (10) comprised of a pair of base rails (20) interlocked in a tongue (32) and groove (22) relationship with a pair of slide rails (30) is disclosed. The rails (20, 30) may be manufactured in a variety of shapes including 'I' beams, rectangles, boxes, or even ovals or circular shapes. Some embodiments of the ladder (10) include a pulley assembly (70) which is fastened to a fly rail rung (50) and a rope (10) is passed through the pulley (70) to form a continuous loop around the rungs (40) of the base set of rail rungs and the fly rail rungs (50). In addition, some embodiments include means (170) for attaching tools to the fly rail.
(FR) Echelle à coulisse (10) comprenant une paire de rails supports (20) associée, par l'intermédiaire d'une languette (32) et d'une rainure (22), à une paire de rails coulissants (30). Les rails (20, 30) peuvent être fabriqués suivant une variété de formes telles que profilés en « I », rectangulaires, boîtes, ou même, ovales ou circulaires. Certaines formes d'exécution de l'échelle (10) comprennent un ensemble à poulies (70) qui est fixé à un échelon (50) du rail mobile, cependant qu'un câble (10) est passé sur la poulie (70) de manière à former une boucle continue autour des échelons (40) du jeu d'échelons du rail fixe et d'échelons (50) du rail mobile. En outre, suivant certaines formes d'exécution, il est prévu des moyens (170) permettant d'attacher des outils au rail mobile.
