ABSTRACT:
A folding easel has three telescoping legs, leg locks for locking each of the legs at arbitrarily extended positions, two tie-bars each hinged at one end to an axle supported on a corresponding leg lock, one tie-bar being snap-engageable to an axle on a third leg lock, the remaining tie-bar being snap-engageable to an intermediate point of the first tie-bar to form a T tie-bar arrangement for maintaining the three legs in fixed spaced apart relationship and usable as a shelf for paint boxes or the like, the tie-bars being readily disengageable without removal of fasteners for folding together of the three legs.
