Abstract: A shelf system comprising a shelf plate having a length defined by a longitudinal axis and a width defined by a latitudinal axis. A series of ribs are molded into the plate on its bottom face. These ribs are offset from the longitudinal axis and the latitudinal axis so that they intersect these axes at non-right angles, preferably forming diamond shaped patterns on the underside of the shelf plate. These diamond shaped patterns are designed to increase the strength of these shelves with a minimal amount of support material.

Abstract: A modular display sign having a base section with a base support rail secured to the base section. A first display section is removably attached to the base support rail in a plane perpendicular to the base section. At least one second display section is removably attached to the first display section in a plane perpendicular to the base section. This arrangement enables the vertical stacking of display sections thereby increasing the display area and adjusting the height of the display sign.

Abstract: A slatwall section having a groove formed above and behind the upper most slat for providing additional structural integrity. The formed groove enables a slatwall to be manufactured having uniform thickness. A mating engagement between upper and lower slatwall sections provides a connection point that is concealed within a formed slat, and thereby eliminates the use of exteriorly disposed sink holes or fasteners.

Abstract: A device for displaying a sign at various heights including a sign holder and a base. The sign holder includes a framed transparent window with hollow frame members disposed along the lateral sides of the sign holder. The sign is removably mounted to the transparent window. The base includes upwardly extending support rods for frictionally and slidably engaging the hollow interior of the frame member. The sign holder and sign are selectively maintained at various heights along the support rod. Upon completely lowering the sign holder, the support rods are completely disposed within the hollow frame members, providing an aesthetically pleasing appearance.

Abstract: A device for displaying a sign at various heights, including a base and a pair of spaced, parallel uprights extending upwardly from the base. A cardholder is slidably positioned between the uprights with the sign being removably mounted to the cardholder. A frictional retaining force exerted between the uprights and the cardholder maintains the cardholder and the sign at various heights.

Abstract: A clamp useful as part of a sign holder which displays identifying characteristics of merchandize on a display rack support rod of circular cross-section. The clamp has an upper housing and a lower housing hingably connected together. The free ends of the housings engage each other as they are overlapped one over the other. When the upper and lower housings overlap, teeth on each are resiliently urged toward each other to engage each other to releasably lock the housings into any desired one of a plurality of relative rod encircling positions. Friction pads are urged by the upper and lower housings against the rod. The pads compress in response to increasing the amount of overlap by relative movement of the upper and lower housings. The clamp completely encircles the rod.
