  • Rotating advertising sign with rotating louvers
    Patent number: 5572816
    Abstract: The sign (10) includes a plurality of elongated louvers (170) arranged parallel to one another in a cylindrical array to form a carousel (30) of louvers rotatable about a central axis (15). Each louver (170) is rotatable about is own length to display different images, with the images of adjacent louvers being coherent to form a progressive coherent image about the carousel, and the louvers are turned on their own axes in timed relationship with respect to one another, either simultaneously or progressively, to change the images. Sign (10) has a circular frame (30) which is rotatably supported on a support base (20). Frame (30) has twelve panel frames (36) which are interconnected to form one rigid circular frame assembly (30) about central axis (15).
