发明名称 Portable drawing board
摘要 A novel drawing board particularly adapted for use in making drawings or sketches from charcoals, pastels or similar materials is disclosed. The drawing board comprises a base member or board and a series of plates which are adapted to be positioned around the outer edge or periphery of the board. The individual plates, which are preferably formed of a transparent plastic, are removably secured to the board and, when secured to the board, form a margin or border for the sheets being held. The plates are secured to the board by bolt or other suitable means positioned through openings and/or slots formed in the base member and plates. In the use of the drawing board, the plates are loosened and are moved perpendicular relative to the edge of the board. One or more sheets of paper are then slipped between the plates and the board with the plates then being adjusted and tightened to secure the paper. The device is easily portable, inexpensively manufactured, and readily and uniquely designed for use in making sketches, drawings or paintings.
