发明名称 Multipurpose easel
摘要 An easel having a pair of segmented front legs and a segmented rear leg member with the legs and segments slidably joined by dovetails and dovetail grooves for varying easel height. The front leg segments, in addition to being extensible, are pivotally joined to the main members of the legs to permit angular positioning of the front leg segments to the vertical to serve as the front legs of the drafting table configuration. In this configuration, the upper ends of the main members are positioned downwardly along the rear leg member to provide a sloping, workpiece supporting surface in the nature of a drafting board. A detachable cross member serves to brace the vertical front leg segments against swaying while a brace assembly braces the connection between the main leg members and the rear leg member.
