ABSTRACT:
Improved portable easel (10) comprising two functional sections, base (12) and arm holder (16) fastened together with locking hinge mechanism (14) formed by adjustable clutches (14A,14B). The arm holder comprises a plurality of members with an elbow-shaped bend (52A,52B), containing a plurality of openings in the distal end attached to the hinge mechanism (14) and a plurality of openings in the proximal end, such that proximal openings are at right angles. This hinge mechanism permits the curved holder to fold down over the base and the legs for compact storage and up for a range of angles. Adjustable length arms (22) are attached to arm holder with adjustable clutches (18), allowing arms to freely pivot in a plane until locked in position. Adjustable support legs (20) are pivotally fastened within angled cutouts (42) in the base. Sliding, adjustable, artwork holders (24) are attached to the arms with adjustable clamps.
