  • Arrangements for facilitating assembly, service and maintenance of image-changing signboards
    Patent number: 7571559
    Abstract: An image-changing signboard comprising an upper and a lower horizontal frame member (12, 14) having a substantially U-shaped cross-section. A plurality of vertical bar-shaped display elements having a triangular cross-section are rotatably mounted in the upper and lower frame members. Individual gear units (26, 32) are mounted in one (12) of the horizontal frame members for rotating a respective display element (18). A drive motor (20) is connected to a common drive shaft (24) for simultaneously rotating respective gear units (26, 32). A plurality of gear units (26, 32) are mounted on a common mounting plate (22) so as to form a drive module, which is slidably mounted on tracks (40) in one (12) of the U-shaped horizontal frame members and which form a bottom plate bridging the gap between the legs of the frame member (12) and facing the signboard display.
