ABSTRACT:
A writing board has a convertible stand. Left and right standards pivot at the writing board's sides by a sliding linking mechanism, and their free ends are formed with hooks so that a selection of the following can be achieved. That is, the writing board might be hung on a door with the hook ends of the standards swung up over the door's top edge. The standards might be swung down to stand the writing board off the floor as a floor stand. The standards' linked ends might be slid up high along the sides of the writing board, and swung back a little, to prop the writing board in the manner as a book easel. Whereas a floor stand manner of standing the writing board puts it between about waist and shoulder high, a book easel manner rests its bottom edge on a desk or podium.
