Storage rack and cross-bar support
First Claim
1. A cross bar for a support frame for a shelf assembly, said shelf assembly including a pair of rear posts extending upward and an opposed pair of front posts extending upward with elongated front and rear deck beams extending between and connected to respective pairs of rear posts and front posts in the same plane and parallel to each other to define a support for a shelf, each of the deck beams having an open cross-section with a vertical beam web and opposing top and bottom flanges extending from the beam web toward an inside of the shelf assembly, the opposing top and bottom flanges being separated by a distance D, the top flange having a width W and being offset vertically by a distance O below a top edge of the vertical beam web, the beam web having at least one pair of vertically aligned connectors extending inward from the beam web, each connector having an enlarged connector head with a short connector shaft extending between the head and shaft, the cross-bar comprising:
- an elongated member having a vertical cross-bar web with at least a top flange extending laterally to a first side of the cross-bar web and at right angles to the cross-bar web, the cross-bar web having a height H which is less than the distance D, the vertical cross-bar web having a reduced height web section with a height R at opposing ends of the elongated member, the reduced height web section having no top flange thereon, each reduced height web section being connected to a connecting bracket that extends laterally to the first side of the cross-bar and at right angles to the reduced height web section, each connecting bracket forming at least two hooks extending laterally in the plane of the connecting bracket with each hook defining a vertical recess and with at least one hook defining a lateral opening for each recess, the recess configured to receive the short connector shaft but not allow passage of the enlarged connector head, each hook sized to fit between the beam web and the enlarged head of the connector during use;
wherein height R of the reduced height web section is smaller than the distance D and height H and is sized to fit vertically between the opposing top and bottom flanges of the deck beam and allow the connector shafts to enter the lateral openings of the at least one hook and move downward so each connector shaft engages a different one of the recesses during use;
wherein the reduced height web section extends from the connecting bracket a distance sufficient so the top flange of the cross-bar is adjacent to the top flange of the deck-beam and the height H of the cross-bar is selected so the top flange of the cross-bar is flush with the top flange of the deck beam.

Abstract
A cross-bar is provided for a shelving assembly having vertical corner posts joined by horizontal deck beams with the cross-bar extending between deck beams to support the shelving material supported by the beams. The cross-bar has an offset connecting bracket at each end. The offset allows the bracket to fit underneath a deck beam flange so the bracket can engage protruding rivets on the inside of open-section deck beams.
