ABSTRACT:
A novel presentation board has a body of molded plastic which forms a strong, hollow, lightweight unit with a projecting tray and grip on a front surface and a corresponding recesses on a rear surface so the units can be conveniently stacked. The front surface of the body bears an extruded track for insertion and replacement of a whiteboard or other writing surface. The whiteboard is secured at a top edge of the body by two metal pegs, sized and spaced apart to accept a prepunched pad of flip chart paper, that pass through the whiteboard into threaded inserts in the plastic body. The grip protrudes from a top edge of the whiteboard and is slidably mounted on the pegs. When slid into a lower position, the grip hides the pegs and locks the pad in position. A pair of U-shaped tubular metal legs can be slid into channels in a rear surface of the body. The channels are covered, at all but part of their lower ends, by cover plates. Grasping the lower leg ends allows one to slide the legs from the unit. One leg slides straight down remaining in the plane of the board. A second leg slides part of the way down and then is automatically pivoted to the rear by torsion springs, thereby forming a convenient prop to elevate the board.
