ABSTRACT:
A folding easel wherein there is an articulated joint between the upper ends of the legs and a further articulated joint between support arms and a central leg. Each articulated joint includes a ball and socket arrangement with there being a loop of elastic cord extending through the legs and the ball and sockets to hold the parts together while functioning as a pivot member. The support arms are secured to the central leg utilizing a similar ball and socket and loop of elastic cord arrangement. An elastic cord also extends between outer ends of the support arms for holding the support arms in the operative state of the easel. The same elastic cord is utilized in association with headed members on lower portions of the legs to pull the lower portions of the legs together in the folded state of the easel.
