  • Patent number: 6202334
    Abstract: Novel point-of-purchase cantilevered deflectable display assemblies, which normally extend transversely into a shopping aisle. Display assemblies which accommodate substitution of one frame-carried form or configuration of advertising for another, which can be radically different, without disconnecting the entire display assembly from its mounting to a molding at a store shelf or like. The advertising frame with which the advertising medium is associated is removably connected to a hanger portion. The hanger portion accommodates the above-mentioned on-site frame and advertisement removal and exchange while the remainder of the display assembly remains in its shelf-mounted or like position. Display assemblies are disclosed which enhance the deflectable nature of the cantilevered distal part of the display assemblies, the manner in which pivoting occurs and is controlled or limited and the way in which the display assemblies are biased toward neutral in the assembled condition.

  • Patent number: 6149340
    Abstract: Apparatus is provided for self-righting a signpost after it has been tipped over comprising a plate for connecting to the signpost and a complementary tray secured to the ground. Most of the apparatus is located below ground out of harm's way. The tray has upturned peripheral edges within which the plate resides. A chain is connected to the plate, extends through a hole in the tray and into the bore of a pipe for connecting to the bottom of a compression spring. When the signpost and plate tip, the plate rotates within the tray, displacing the chain and compressing the spring. Preferably a lip extending over the edge of the plate causes the plate to ride up the edge of the tray, increasing the chain's displacement. The increased tension in the chain urges the plate and signpost to right themselves. The plate and tray are complementary and square shape so that the square sides engage during tipping and prevent rotation of the signpost's orientation when it returns to the upright position.
