Telescopic ladder and locking mechanism thereof
A locking mechanism for selectively securing and unsecuring the linkage of individual ladder sections of a telescopic ladder. The locking mechanism is shifted into a locked position by pivoting a lever toward a first rotational trajectory, urging a track follower in a first direction along a guiding track, and linearly displacing at least one securing rod into an aperture through multiple ladder sections, securing the linkage of the ladder sections. A lever-securing mechanism form-fittingly secures the lever within a bridge element of the locking mechanism when in a locked position. The locking mechanism is shifted into an unlocked position by pivoting the lever toward a second rotational trajectory opposite the first rotational trajectory, urging the track follower in an opposite direction along the guiding track, and linearly displacing the securing rods out from the aperture through the multiple ladder sections, unsecuring the linkage of the ladder sections.
