ABSTRACT:
The purpose of this invention is to provide an easel assembly reversibly transformable between a deployed position suitable for supporting at least one planar item thereon and a collapsed position suitable for transport and storage. The easel assembly includes a pair of support members. Each support member is pivotally interconnected for selective movement between a folded position where said support members are generally parallel and a deployed position where said support members divaricate. In addition, each support member is integrally connected to a base member which is constructed and arranged for removable, pivotal interconnection at the end opposite the support member. The connected base members are constructed and arranged for positioning on a planar surface when the easel assembly is in the deployed position, thereby distributing any downward load of the easel assembly along the planar surface to resist tipping and maintain the stability of the deployed easel. The support members also include an upper and lower portion which are connected together in a manner that allows the easel assembly to attain a collapsed state suitable for transport and storage.
