| 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 permits of rocking motion and 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 the 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 provided on adjacent portions of the two parts. The panel is preferably provided with a transverse edge flange that bound the region adapted to receive a removable display sheet thereonto. In alternate forms of construction, the concept of a convex support side that permits of rocking motion of the poster display is preserved, but the ballasting of the poster display is secured through a plate of heavy density material located either within the hollow support base, or on the exterior of the convex support side of the base of the rocking display, and with the center of gravity of the ballasting located substantially in the medial vertical plane through the poster display device. In another alternate form of construction, the display does not rock, but the poster display is free to swing relative to the support structure.

First Claim:
Show all 4 claims |
What is claimed and desired to be secured by Letters Patent of the United States is:
1. In a self-righting, rockable, display device that is adapted to be positioned out-of-doors and to be moved by wind blowing thereagainst, and having an axially elongated arcuate lowermost convex rocking wall portion, about which rocking of the display device, in response to wind, takes place, and wherein the display device includes a pair of identical, vertically elongated, segments, that are joined together in mirror image relationship along a continuous, peripheral, elongated seam that extends along the entire vertical height and width of the rockable display device;
- the improvement comprising, in combination: a transverse shelf mounted above said convex rocking wall portion and serving to divide the display device into an upper section above which an advertising display is to be positioned, and a lower section, said transverse shelf being smaller in cross sectional area than the lower section and at least as large in cross sectional area as the upper section;
- said upper section being further shaped to provide a pair of laterally spaced sides connected to and extending above the transverse shelf to bound a sign holding section that is adapted to hold a pair of oppositely facing display panels positioned above the transverse shelf and between the pair of upright sides that extend above the transverse shelf;
- said lower section including a pair of laterally spaced, lower upright side walls which are coplanar with said pair of lateral upright sides that extend above the transverse shelf, said laterally spaced, lower upright side walls extending below said transverse shelf and being joined to the axial ends of said axially elongated convex rocking wall portion;
- said pair of vertically elongated segments being molded of plastic to provide a lightweight construction; and
- weighting means carried by said lower section to provide stability for the lightweight construction, and to cause said self-righting display to be normally positioned in an upright attitude.
