Abstract
A foldable easel strut assembly is provided for supporting the easel when the easel is in use, and for moving the legs of the easel to a storage position when the easel is to be stored. The invention comprises an easel support board to which a rear leg assembly is pivotally connected. A pair of forward struts are pivotally connected at a first end to the support board. A pair of rear struts each have a first end pivotally connected to a second end of a corresponding forward strut, and a second end of each rear strut is pivotally connected to the rear leg assembly. Each rear strut includes a stop flange that abuts an upper edge of a corresponding forward strut when the rear leg assembly is pivoted away from the support board to a maximum position. In an embodiment, two front legs are pivotally connected to the support board, and the rear leg assembly comprises a rear leg member that pivotally folds against a bracket, and the bracket folds against the support board, when the easel is in its storage position.
