ECHELLE D'ACCES
Abstract:
(EN)
A two rung ladder (2, 3), with treads (4), attached to a sliding mainframe (1), which slides within sliding channels (19) of a mountable carriage. When withdrawn, a self-lifting bar (8) is activated by contact with stop bar (21), which raises telescopic tubes (9, 10), pivoted at swivel plates (14), to the position shown. Inner tubes (10) can be raised within outer tubes (9) and locked in position by locking pin (18) in locking location slot (12), so as to provide safety handles. The ladder assembly is locked into position by swivel action lock, (23, 24, & 25), which locates in locking device slot (16) provided in standing platform (15) attached to mainframe (1). By releasing the swivel action lock (23, 24 & 25), the ladder assembly can be easily stowed by sliding back into the sliding channels (19), the handles (27) being protected by protection plates (5) when stowed away.
(FR)
L'invention concerne une échelle à deux échelons (2, 3), munie de deux échelons (4), fixés sur un cadre principal (19 coulissant, qui coulisse dans des canaux de coulissement (19) d'un chariot montable. Lorsque ladite échelle est enlevée, une barre auto-levante (8) est activée par contact avec la barre d'arrêt (21) qui élève des tubes télescopiques (9, 10), qui sont mis en pivotement au niveau de plaques basculantes (14), pour passer dans la position indiquée. Des tubes intérieurs (10) peuvent être élevés dans des tubes extérieurs (9) et être bloqués en position par une goupille de verrouillage (18), dans une fente de position de blocage (12), de sorte à fournir des poignées de sécurité. Le système d'échelle est bloqué en position par verrou à action de basculement (23, 24 & 25), qui se trouve dans une fente de dispositif de blocage (16), aménagée dans une plate-forme verticale (15) fixée au cadre principal (1). Le fait de relâcher le verrou à action de basculement (23, 24 & 25) permet d'arrimer aisément le système d'échelle, par coulissement arrière des canaux de coulissement (19), les poignées (27) étant protégées par des plaques de protection (5), lorsqu'elles sont casées.
