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： 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.
