Abstract:
The invention relates to a telescopically extendable and collapsible ladder assembly having a top ladder section, a bottom ladder section, and one or more intermediate ladder sections. According to a first aspect of the invention sliding automatic release actuators are provided, having a slanted actuating surface for interaction with actuator surfaces of spacers provided at each end of a rung of an adjacent ladder section, such that, when a rung is moved towards the rung of an adjacent lower ladder section, the activation surfaces of the spacers push the release actuators into an unlocking position and subsequently position the rung at an anti-finger pinching distance. According to a second aspect of the invention, the top rung of the bottom ladder section is provided with a centrally arranged grip element that forms a housing for manually operable release actuators provided at the bottom side of the rung.
