Abstract:
1. A modular ladder assembly adapted to be placed on a support surface comprising: at least two ladder assemblies, each assembly having first and second parallel stiles and a plurality of spaced apart rungs disposed between said first and second stiles, said plurality of rungs being perpendicular to said first and second stiles; at least one adjustment assembly having first and second ends; at least one first type of fastener arrangement; at least two second type of fastener arrangements; wherein respective first stiles of said at least two ladder assemblies are mechanically connected together by said at least one first type of fastener arrangement and respective first stiles are parallel to each other; and wherein said first end of said at least one adjustment assembly is mechanically connected to said second stile of one of said at least two ladder assemblies by one of said at least two second type of fastener arrangements and wherein said second end of said at least one adjustment assembly is mechanically connected to said second stile of a second of said at least two ladder assemblies by a second of said at least two second type of fastener arrangements so that said at least two ladder assemblies and said at least one adjustment assembly have a triangular shape when viewed from a plane perpendicular to said first and second stiles of said at least two ladder assemblies; and wherein said modular ladder assembly has a folded position where said at least two ladder assemblies are substantially parallel to each other and a working position where said at least two ladder assemblies are substantially perpendicular to the support surface on which said two ladder assemblies are positioned, wherein at least one of said at least two ladder assemblies further comprises more than one attachment points to selectively connect said first of said at least one adjustment assembly to said second stile of one of said at least two ladder assemblies, the selection of attachment points determining a vertex angle between said at least two ladder assemblies.
