Portable Easel With Table

US Patent:
5501423, Mar 26, 1996
Filed:
Oct 6, 1994
Appl. No.:
8/319314
Inventors:
William L. Roberts - San Bernardino CA
International Classification:
A47B 9704
US Classification:
2484411
Abstract:
A portable easel with tray and table composed of two legs, joined at the top by a crosspiece having in it pegs for hanging a thin, rigid easel board to serve as backing for commercially available easel pads. The legs pass through holes at their approximate midpoint in a tray table which senses as a tray for marking instruments in the front, a table for papers, books and the like in the rear, and which holds the legs in their splayed position. The tray table rests on fittings which support the upper structures, join the legs laterally for rigidity at their midpoint, and into which the lower portion of the legs may be fitted and removed. The lower ends of the legs have rubber tips to increase friction with the floor, or may be attached to a rectangular base to afford greater stability. The lower halves of the legs, when removed, enable the easel to function as a table model, and reduce the size of the structure for transport and storage. The structure will support chalk boards, white boards and bulletin boards on both its front and rear faces.
