Abstract
Abstract A convertible drawing article of furniture includes a support structure and a drawing board which can be mounted on the support structure in a prostrate position or in an upright position, so that the assembly can be used as a drawing desk or as an easel. The drawing board includes a mounting frame and a slate board which is supported on a circumferential recessed ledge of the frame and held thereon at its front corners by holding members. A compartmentalized tray is attached by compatible male and female connecting formations to the lateral section of the mounting frame in the prostrate position and to the front region of a support frame forming a part of the support structure in the upright position of the drawing board. The support structure further includes two front and two rear legs, of which the rear legs are telescopically extendable so that the drawing board can rest thereon in its upright position while its then lower section is engaged with rear projections of the tray. An embellishing accessory is mounted on the rear section of the drawing board in two possible orientations in one of which it extends substantially normal to, and in the other substantially along, the plane of the drawing board, by cooperating male and female attaching formations.
