Abstract:
1. A holding system comprising: a first ladder having a first side C-shaped rail having a web and opposed curved flanges with a tip; a second ladder having a second C-shaped side rail having a web and opposed curved flanges with a tip; and a clip maintaining the first side rail of the first ladder adjacent to the second side rail of the second ladder which is in series with the first side rail comprising: a first U shaped portion having a first leg with a hook and a second leg connected to a support element and a second U shaped portion having third and fourth legs connected to the support element, the first portion, the second portion and the support element are one continuous piece, the first portion defining a hooking engagement with the first side rail and the second portion defining a receiving engagement with the second side rail, said first and second portion opening from opposite sides of said support element, respectively, and conform to outer surface of the curved flange of respective side rail that it receives, and removably and frictionally holding the respective side rails in a self-gripping and form-fitting manner such that the respective 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 respective side rails under dynamic conditions brought about by motion during transportation, the hook has a first part which is curved toward the support element and a second part which is extends from the first part essentially perpendicularly towards a center of the first rail, the hook is adapted to contact and extend along and hold an inner surface of the first side rail flange, a surface of the support element and an inner surface of the first leg form a first curved surface and an inner surface of said first part and second part forms a second curved surface facing the first curved surface, one of the curved flange and tip of the first side rail being matingly, enveloped between the first and second curved surfaces, the legs and the support element are formed of molded plastic.
