  • Patent number: 8016077
    Abstract: A clip for maintaining a first side rail of a first ladder adjacent to a second side rail of a second ladder which is in series with the first side rail. The clip includes a first portion connected to a support element and a second portion connected to the support element. The first portion, second portion and support element are one continuous piece. The first portion defines a hooking engagement with the first side rail and the second portion defines a receiving engagement with the second side rail. The first and second portion opening from opposite sides of the support element, respectively, which conform to the portion of the respective side rail that it receives for removably and frictionally holding the respective side rails in a self-gripping and form-fitting manner such that the side rails are maintained adjacent and in series to each other so that no damage is possible to the ladders by relative movement of the side rails under dynamic conditions brought about by motion during transportation.

  • Publication number: 20050178617
    Abstract: A dynamic hinge includes a first member connected to a first ladder portion of a ladder, and a second member connected to a second ladder portion. The first member pivots relative to the second member about a pivot axis that does not intersect both the first and second members. The first member includes first and second parallel segments, and the second member includes a third and fourth parallel segments. A guide plate is attached to either the first or second member, and the guide plate is positioned between the first and second segments and between the third and fourth segments. The guide plate includes two non-linear slots, and an other of the first and second members includes two pins, respectively adapted to slide within the two non-linear slots. The pins extend between either the first and second segments or the third and fourth segments.
