Abstract
Abstract A TWO-POSITION CONVERTIBLE DESK HAVING A PANEL UNIT WHICH CAN BE RAISED TO PROVIDE PRIVACY FOR INDIVIDUAL LEARNING SITUATIONS AND LOWERED TO RETRACT DIVIDER PANELS FOR GROUP LEARNING SITUATIONS. THE PANEL UNIT INCLUDES A REAR PANEL WHICH SERVES AS A SCREEN WHEN THE PANEL UNIT IS RAISED, AND WING PANELS WHICH DIVIDE THE DESK INTO TWO WORKING AREAS WHEN THE PANEL UNIT IS RAISED. WHEN THE PANEL UNIT IS LOWERED, THE REAR PANEL EXTENDS THE WORKING AREA OF THE DESK, AND THE WING PANELS RETRACT NEARLY OUT OF THE WAY.
