Abstract
Rotating displays include rotation mechanisms which allow the displays to be easily rotated by consumers, yet automatically returned to one or more desired positions when released by the consumer. Holders for the display are affixed to turntables rotatably mounted upon a base wherein the turntables are attached to a biasing means capable of exerting a sufficient torque upon said turntable, relative to said base to cause an angular acceleration of said turntable toward a predetermined desired orientation. In preferred embodiments, the amplitude of the torque may be adjusted, depending upon the moment of inertia of the display, to cause a predetermined angular acceleration. The number and placement of equilibrium orientations may be selected based upon the desired geometric configuration of the display with which the rotation mechanism is to be used.
