(54) | Ladder articulation |
(57) This invention covers an ARTICULATION suitable for simple articulated ladders with
two or more step sectors, extension articulated ladders or telescopic ladders. This
articulation has elongated arms with castings near the ends of a varied geometric
configuration, whereby this geometric configuration is always the same as the periphery
of the members used for the ladder steps. The castings (1 and 2) allow the step closest
to the articulation (3) to be applied by crossing the articulation arm and the flange
where it was inserted, such that it is flared on the outside (4), adjusting and fastening
the articulation.
