Abstract

The drawing horse and multi-task work station is adapted to support a planar board for use by a user. The station includes a generally rectangular, three dimensional central frame structure having a width small enough to be straddled by the user. Planar, rectangular end frame structures are mounted on either end of the central frame structure. The end frame structures include upwardly extending frame portions with a pair of extending end posts thereat. In one embodiment, the work station is provided with a removable drafting board system having pivotal end support elements, supporting the drafting board thereon, mounted to left and right side cross support beams. The cross support beams are removably mounted on the end posts of the end frame structures with end post caps. The caps are at either end of the cross support beams. In another embodiment, the station includes a tray. The bottom side of the tray has a complementary shape to mate with the open frame work of one of the end frame structures such that, when the central frame structure is turned on its end and the end frame structures are vertically aligned (one on the ground plane and the other elevated by the central frame structure), the tray sits atop the open frame work of the raised end frame structure. Other accessories include a drawing board and a vertical support structure for the planar drawing board removably mounted atop the tray, an easel which is an adjustable vertical support structure for painting surfaces removably mounted atop the tray and locked securely to the station, depending legs for each of the end frame structures, and wheels mounted on the terminal ends of the depending legs.
