  • Patent number: 5499467
    Abstract: An information stand with a plurality of faces which are successively exposed to a viewer. The stand has a rigid hollow frame within which one or more multi-face information carrier elements are positioned. The frame has a pair of unequal in length parallel vertical sides and inclined upper and lower parts. Each of the information carrier elements is fixedly attached to a rotational shaft. A plurality of lever arms extend in a symmetrical relationship from the shaft, each of the lever arms being fixedly attached, at one end, to the shaft. A free end of each of the lever arms is intermittently received within a shorter side of the frame. A weight descends under gravity within the shorter side and contacts the free end of the lever arm, imparting rotation on the lever arm, the shaft and the information carrier element. A powered drive lifts the weight within the longer side of the frame, from where the weight moves again under gravity to cause rotation of the information carrier element.
