Abstract

An improved electronic price display system has rails into which are installed price display labels. Ridges along the top and bottom of the rails are shaped to receive a label readily. A removal tool may be engaged to release the pawls of the label to extract the label. Ridges at the rear of the rails, together with a resilient insert, permit quick mounting to a shelf with a minimal number of fasteners. A hemicylindrical feature at the back of the rails permits generous area of contact with a mounting screw having a hemispherical head. Opposed groove features permit the concealment of the screw heads and provide a visual design element. Angled ridges on the rear face of the label engage with knurls on the rails providing contact wiping, enhancing electrical integrity of the label-to-rail connection, and also fix the label in place. A feature along an edge of the rail provides a cylindrical concavity. An optional clear plastic cover mounted with a cylindrical edge bead in the concavity provides a hinged connection therebetween. A protruding button on the face of the label is actuated by the pressing of the cover in the vicinity of the button. A subassembly of the label provides a robust carrier for springy contacts providing electrical connection long conductors on the rails.
