Abstract
A mechanical arm mechanism for moving a table or similar board type work surface in an arcuate path from a stored position to one or more user positions at various selected elevations and angles of inclination. The mechanism uses at least one set of spaced apart arms each of which has one end pivotally attached to a respective fixed pivot point on a support member and the opposite end pivotally attached to a respective movable pivot point on the bottom or back side of a board member with the lengths between the fixed pivot points, the moveable pivot points and the arms forming the sides of a trapezoid which sides change their relative angular orientation as the table or board is moved in its arcuate path of travel.
