Locking assembly for a telescoping ladder
Embodiments include a telescoping ladder with a plurality of columns and rungs. The ladder can have a plurality of locking assemblies for locking adjacent columns to a rung thereby restricting relative sliding motion between adjacent columns. The locking assembly can have a locking button positionable against the rung front surface and rotatable with respect thereto between a locked position and an unlocked position. The locking assembly can have a locking pin positioned within the rung and slidable between an extended position and a retracted position along a locking pin axis generally perpendicular to the rotational axis. The locking assembly can have a connector pin extending in a direction parallel to the rotational axis, for connecting the locking button to the locking pin such that rotation of the locking button about the rotational axis slides the locking pin about the locking pin axis.
