ABSTRACT:
An adjustable and collapsible easel having a plurality inner and outer telescoping leg sections. The upper ends of the outer leg sections are connected to a common connecting member for articulated movement between fully spread and fully folded positions. The outer ends of a plurality of foldable brace members are connected to respective ones of the outer leg sections and the inner ends of the brace members are connected to a common fitting. The brace members reinforce and hold the legs in an operative, spread position. Cam surfaces on the outer ends of the brace members engage and prevent telescoping movement of the inner leg sections relative to the outer leg sections when the legs are in either fully spread or fully folded positions. The length of the legs and locking of the same in their operative, fully spread position is effected by depressing the fitting which interconnects the inner ends of the brace members. Support means for supporting an article to be displayed on the easel is slidably and rotatably mounted on at least one of the upper leg sections. Each support means includes a pivotally mounted arm which serves to releasably lock the support means in an adjusted position on its leg section when the arm is pivoted to an outwardly extending, operative position.
