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.

Information display rail system

A vertical stringer or rail system is provided for use with an electronic price display system in a store, warehouse or other application. A vertical rail is made of an insulating material and is of substantially constant cross section along its extent, with ridges along each edge. A channel in the front face of the rail carries a plurality of exposed conductors, and the channel and edges are keyed. Snap-on connectors fit to the rail, and due to the keying it is impossible to snap the connector on backwards. The snap-on connectors each have a flat cable running to a shelf rail at the front of a shelf, and electronic price display labels lie within the shelf rail. U-shaped snap-on cable clamps provide clamping of the flat cable to the vertical rail nearby to the snap-on connectors, and the cable clamps are captive to the flat cable so they are not easily misplaced. Because the snap-on connectors and clamps may be snapped on at a multitude of locations they can easily accommodate shelves at varying heights. Shelf moves are easily accommodated regardless of starting and ending shelf positions.
