| Abstract: |
A poster display, subject to out-of-door wind forces that will develop substantial overturning forces against the poster display, is provided with a self-righting feature by using a hollow support base, with a convex support side, that is ballasted by a flowable ballast material such as water, and upon which base, an upright, wind-catching, panel is mounted to project away from said convex support side. The base and panel are molded of inexpensive plastics. The base and panel may be formed as separate parts, or as an integral assemblage. In one preferred construction the base and panel are separate parts, have interfitting tongue and socket means provided on adjacent portions of the two parts. The panel is preferably provided with transverse edge flange means that bound the region adapted to receive a removable display sheet thereonto.

| Claim |
What is claimed and desired to be secured by Letters Patent of the United States is:
1. In a self-righting display device, the combination of a self-righting hollow base, shaped to provide an elongated rocking body with a laterally elongated, convex, lowermost rocking wall, a laterally elongated, flat, rectangular upper wall spaced opposite the convex rocking wall, said upper wall having one pair of opposed end edges and a pair of opposed side edges, the end edges being transverse to the side edges; and four upright side walls, each side wall extending from one edge of the laterally elongated upper wall to an edge of the convex rocking wall, to provide a first pair of parallel, spaced, upright end walls of partially frustro-conical shape, as seen in elevation, and a second pair of side walls that are outwardly inclined from an elongated edge of the upper wall to an elongated edge of the convex rocking wall, and the lateral ends of each side wall being integral with an edge of an end wall to provide a hollow six-sided base for the self-righting display device, said six sides of said laterally elongated six-sided base bounding a hollow chamber that is adapted to receive and hold therein a flowable ballast material to provide a substantial weight within the base;
- the base being formed of plastic to provide a lightweight body;
- one upright wall of the base having a selectively openable and closeable aperture provided therein, through which a flowable ballast may be introduced into the hollow chamber of the base;
- a rigid display panel means that is provided separable from said base, but is adapted to be easily assembled on the base, in the field, to be supported on the base, said display panel means providing a bottom edge of a size and shape to abut only the upper wall of the base;
- the upper wall of the base having an upstanding laterally elongated tongue thereon; and
- the lower edge of said rigid display panel means having a single non-circular socket, generally congruent with said tongue, for receiving thereinto, in telescoping cooperation said upstanding laterally elongated tongue of the base, to provide a structurally sound interconnection between said base and said rigid display panel means.
