COLLAPSIBLE LADDER

摘要

There is provided a collapsible ladder comprising several collapsible ladder sections, each or at least part of the ladder sections comprising two hollow ladder bars arranged parallel to each other and interconnected at an upper end by a rung, and each collapsible ladder section being telescopically inserted into a lower ladder section. Each ladder bar of a collapsible ladder section has a locking hole adjacent the lower end part of the ladder bar and an extension below the locking hole. Retaining mechanisms are provided in at least part of the rungs for locking the collapsible ladder sections relative to one another when the collapsible ladder sections are extended, each of or part of said retaining mechanisms comprising a locking pin, which can be brought into an extended and locked position in order to engage a corresponding locking hole provided in the ladder bar of a ladder section positioned there above, and each of or part of said retaining mechanisms further comprising a release part with a release lever or arm for retracting the locking pin from the locked position into the un-locked position. For at least one lower ladder section two actuating elements are provided on top of the rung of the lower ladder section with one actuating element at each end of the rung, each said actuating element being arranged for actuating a release lever of a retaining mechanism provided in the rung of an above positioned ladder section, and each of said actuating elements having an inner side face extending in a direction along a corresponding ladder bar of the above positioned ladder section. It is preferred that an upper part of an outer side face of the actuating element is inclined inward towards the ladder bar resulting in an acute angleαof not above 45° between the ladder bar and the upper part of the outer side face of the actuating element. Thus, the actuating element may urge the fingers or a body part of a user to be displaced laterally when the rung of the above ladder section is moving downwards when collapsing the ladder. It is also preferred that the release levers or arms of the above positioned ladder section has an at least partly inclined or convex end part for contacting the inclined upper part of the corresponding actuating elements of the lower ladder section.
