Abstract
A variable slant work board pivotally mounted to a base such as a table or desk. A winch actuated segmented arm supplies an upward force on the underside of the work board to pivot it upwardly toward the fully raised vertical position. A horizontally disposed expansion spring is attached by cable to the underside of the work board to bias it toward the fully lowered horizontal position. The work board is infinitely adjustable between the vertical and horizontal positions.
