A folding artist\s easel, particularly suited for a classroom or teaching environment, utilizes square steel tubing to form a rigid triangular base, a supporting column, and a telescopic brace, with pivotal connections therebetween. The pivotal connections are substantially free of side play and along with connection of the supporting column to a mid-point of one side of the triangular base and connection of the brace to an apex opposite this side, superior stability is provided as well as a minimum required floor space to the rear of the easel, a feature which is particularly desirable in a classroom. A workpiece, such as a drawing board or canvas stretched on a frame, is securely and gently clamped to the easel by means of individually adjustable upper and lower steel cross-members which permit adjustment in the elevation of the workpiece as well as clamping a workpiece of great height. The top of the column is adapted to receive an extension for further increasing the effective height of the easel. Either or both of the adjustable cross-members may be provided with V-shaped parts for receiving the workpiece, thus firmly securing the workpiece against forward and rearward movement on the easel, or the lower cross-piece may have an upwardly opening channel for receiving the workpiece. The entire easel is preferably galvanized steel to assure a rust-free unit as well as increasing the weight of the easel. Galvanizing is particularly advantageous for the lower cross-member in that hardened paint which tends to collect on the lower cross-member may be scraped or otherwise removed therefrom without damaging the cross-member. When the easel is folded either or both the brace or the lower cross-member may be secured in place to retain the easel in its folded position, and the pivotal connection between the base and the brace interlocks with the column to prevent side movement between these parts.

An easel comprising, a base, and column and brace members, means pivotally securing said members to each other and each to spaced apart portions of said base for swinging movement about substantially parallel axes between an erect operative position and a folded position, the securing means including a bifurcated part secured to said base and embracing an end of a first of said members with the first member pivoted to said part for said swinging movement, and when in said folded position the base, column and brace are generally parallel to each other and the bifurcation of the part embraces the other of said members to hold said members against movement transversely of each other, and means for mounting a workpiece on the column.
