  • Patent number: 4299043
    Abstract: A generally rectangular framework is constructed to hold a plurality of individual advertizing panels. The bottom and two sides of the frame are formed from channel members connected at their corners and designed to snugly but freely receive the plurality of panels. A pair of panel support members which are formed as parallel spaced walls extend between the tops of the side channel members and form the top of the framework. Each wall is connected to the ends of the legs of an angle iron member, the apexes of which are facing and spaced horizontally by approximately the width of the panels. The apexes are spaced vertically by an amount to allow the panels to be slid between them at an angular orientation so that the panels can be lifted in an angled position, pulled between the angle iron members, and rotated to a vertical position to be dropped between the sides of the channel member on the bottom of the framework.
