Abstract

A system includes a board having opposing surfaces and at least one leg connected to one surface of the board through a first pivotable fitting to allow the board and the leg to move between a first position wherein the board and the leg are substantially parallel and a second position wherein the board and the leg are substantially perpendicular. The system also includes a locking mechanism secured to the board through a second pivotable fitting at a first end and configured to rotate at a second end opposite the first end between a storage position extending parallel with the board and a work position extending perpendicular to the board.

20. The board of claim 19 wherein the privacy shield includes a flexible covering and a biasing mechanism arranged within the flexible covering configured to bias the privacy shield to extend substantially perpendicular to the worksurface when the worksurface is in the first position.

21. The board of claim 20 wherein the biasing mechanism is configured to be overcome as the worksurface is rotated along the first path to the second position to cause the majority of the privacy shield to extend substantially parallel with the board.

22. The board of claim 1 wherein worksurface forms one of a tabletop, an easel, a display, a blackboard, and a podium.

23. A system comprising:
