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 includes a first stile and a second stile and a plurality of rungs extending therebetween. Each stile may comprise a plurality of columns disposed in a nested arrangement for relative axial movement in a telescopic fashion. A connector assembly 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 telescoping ladder includes a stabilizer connected to a stabilizer housing proximal to the floor surface on which the ladder is positioned. The first stabilizer can move between an extended position and a collapsed position. In the extended position, the first stabilizer extends out of a hollow body portion of the stabilizer housing and collapse into the hollow body portion of the rung in the collapsed position. The stabilizer comprises a locking button to lock the stabilizer in its extended position. The ladder comprises a flange that can release the locking button thereby unlocking the stabilizer from its extended position and move it into the collapsed position.
