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.

I claim: 1. A combination writing board and convertible stand, comprising: a generally planar writing board having a framed portion and a frame of left and right stiles as well as top and bottom rails surrounding the framed portion; left and right standards extending between linked ends pivotally linked to the left and right stiles, respectively, and free ends formed with crook spans; manually-operated pivot-locks for locking the standards in fixed angular positions relative the stiles; wherein the standards and crook spans are sized and arranged so the standards can be: pivoted and locked with the crook spans disposed above the link ends as well as contained in planes generally perpendicular to the writing board and thereby simulating hooks adapted for hooking over a top edge of a door and thus suspending the writing board for abutting the door, pivoted and locked with the crook spans situated generally level with and behind the bottom rail and thereby prop up the writing board with the crook spans and bottom rail resting on a common base surface, and pivoted and locked with the crook spans disposed generally level with or lower than the bottom rail and thereby simulating feet to stand the writing board up off a given base surface. 2. The combination writing board and convertible stand of claim 1 further comprising: left and right sliding links engaged on the left and right stiles for axially sliding therealong and formed with pivot-formations for forming pivotal links with the left and right standards, respectively; and manually-operated slide-locks for locking the links in fixed axial positions on the stiles. 3. The combination writing board and convertible stand of claim 1 wherein, with pivoted and locked with the crook spans disposed generally level with or lower than the bottom rail and thereby simulating feet to stand the writing board up off a given base surface, the standards can furthermore be: linked to the stiles such that the crook spans are contained in planes generally parallel with or co-planar to the writing board and thereby stand the writing board on the given base surface while the writing board leans against a vertical surface. 4. The combination writing board and convertible stand of claim 3 further comprising a receiver mounted high up on the writing board and adapted for receiving a hanger or fastener in the vertical support surface for stabilizing the writing board relative to said vertical support surface. 5. The combination writing board and convertible stand of claim 3 wherein the left and right stiles are provided with dual linking provisions for linking the left and right standards, one which has the standards swinging in planes generally perpendicular to the writing board, and the other which has the standards swinging in planes generally parallel or co-planar to the writing board. 6. The combination writing board and convertible stand of claim 1 wherein: the standards comprise joints intermediate the ends thereof which partition the standards into inner and outer spans and which are at least releasably lockable in extension; and the standards can furthermore be pivoted and locked with the joints flexed and situated generally level with and behind the bottom rail and thereby prop up the writing board with the joints and bottom rail resting on the common base surface. 7. The combination writing board and convertible stand of claim 6 wherein the joints are flexed to dispose the crook spans proximate the bottom rail. 8. The combination writing board and convertible stand of claim 6 wherein the joints are flexed to rest the outer spans on the common base surface. 9. The combination writing board and convertible stand of claim 1 wherein the crook spans rake back beyond a right angle to increase stability when hooked over the top edge of doors. 10. The combination writing board and convertible stand of claim 1 wherein crook spans terminate in hooked-back tip ends to reduce chances of dislodgment of the crook spans when hooked over the top edge of doors. 11. The combination writing board and convertible stand of claim 1 wherein, with the standards pivoted and locked with the crook spans disposed generally level with or lower than the bottom rail and thereby simulating feet to stand the writing board up off a given base surface, the standards can furthermore be: linked to the stiles such that the crook spans are contained in planes generally perpendicular to the writing board. 12. The combination writing board and convertible stand of claim 11 further comprising a receiver mounted high up on the writing board and adapted for receiving a hanger or fastener in a vertical support surface for stabilizing the writing board in a lean against said vertical support surface. 13. A combination writing board and convertible stand, comprising: a generally planar writing board having a framed portion and a frame of left and right stiles as well as top and bottom rails surrounding the framed portion; left and right standards extending between linked ends pivotally linked to the left and right stiles, respectively, and free ends formed with crook spans; manually-operated pivot-locks for locking the standards in fixed angular positions relative the stiles; wherein the standards and crook spans are sized and arranged so the standards can be set in any two settings chosen from the following group: a) pivoted and locked with the crook spans disposed above the link ends as well as contained in planes generally perpendicular to the writing board and thereby simulating hooks adapted for hooking over a top edge of a door and thus suspending the writing board for abutting the door, b) pivoted and locked with the crook spans situated generally level with and behind the bottom rail and thereby prop up the writing board with the crook spans and bottom rail resting on a common base surface, c) pivoted and locked with the crook spans disposed generally level with or lower than the bottom rail and thereby simulating feet to stand the writing board up off a given base surface, and furthermore linked to the stiles such that the crook spans are contained in planes generally parallel with or co-planar to the writing board and thereby stand the writing board on the given base surface while leaned against a vertical surface, and d) standards pivoted and locked with the crook spans disposed generally level with or lower than the bottom rail and thereby simulating feet to stand the writing board up off a given base surface, and furthermore linked to the stiles such that the crook spans are contained in planes generally perpendicular to the writing board. 14. The combination writing board and convertible stand of claim 13 further comprising: left and right sliding links engaged on the left and right stiles for axially sliding therealong and formed with pivot-formations for forming pivotal links with the left and right standards, respectively; and manually-operated slide-locks for locking the links in fixed axial positions on the stiles. 15. The combination writing board and convertible stand of claim 13 wherein the left and right stiles are provided with dual linking provisions for linking the left and right standards, one which has the standards swinging in planes generally perpendicular to the writing board, and the other which has the standards swinging in planes generally parallel or co-planar to the writing board. 16.
