摘要： A telescoping ladder is provided, that includes a plurality of columns disposed in a nested arrangement for relative axial movement in a telescopic fashion between a fully-extended position and a collapsed position. The columns are connected to rungs by way of connector assemblies. Each connector assembly has a locking pin moveable between an extended position or a retracted position for extending into or retracting out of openings of adjacent columns to selectively lock or release the columns respectively. The telescoping ladder includes a plurality of actuators that permit collapsing the ladder in a sequential manner, the sequence involving collapsing the columns on a lower portion of the ladder prior to collapsing columns immediately thereabove.

摘要： An extendable/retractable ladder assembly (100) includes a first stile (104) and a second stile (106) and a plurality of rungs (118,120,150) extending therebetween. Each stile may comprise a plurality of columns (108,110,112,114) disposed in a nested arrangement for relative axial movement in a telescopic fashion. A connector assembly (116) connects the rungs to respective columns in the first and second stiles. The ladder has improved manufacturability since connector assemblies may be assembled before connecting the rungs to respective columns. The standing surface of the rungs may be angled such that it is rotated towards horizontal when the ladder assembly is leaned against a wall. A latch assembly may be used to selectively lock relative axial movement between adjacent columns. The latch assembly includes a locking pin assembly comprised of a central post and an outer metal sleeve. An air damper may also be used to control airflow through the columns.

摘要： A foldable ladder has a first ladder portion and a second ladder portion hingedly attached to the first ladder portion by a pair of hinge mechanisms. Each hinge mechanism adapted to lock the first and second ladder portions such that the first ladder portion and the second ladder portion form an angle therebetween. The hinge mechanism has a shifting mechanism and a ladder angle selector coupled thereto to allow manual selection of the angle between the first and second ladder portions, and a locking pin to lock the first and second ladder portions at an angular position.

摘要： An extendable/retractable ladder assembly includes a first column and a second column, the first column nesting in the second column, and a first rung coupled to, and extending from the second column. A ladder assembly bracket includes a collar portion, which extends about the second column, and a rung portion, which extends from the collar portion into the first rung. The collar portion may be gripped by a hand of an operator in order to position a thumb of the hand in engagement with a button to retract a locking pin of a latch assembly mounted within the rung portion of the bracket.
