Storage rack beam having surface enabling indicia at high or low elevation to be easily read
First Claim
1. A storage rack positioned on a substantially horizontal surface, said storage rack including a front portion facing toward an aisle and a rear portion facing away from the aisle, said storage rack comprising an upright frame and means including a tubular support beam made of steel and connected to the upright frame for supporting a pallet load, said support beam including at least four integral, generally flat walls, said integral, generally flat walls including an upper, substantially horizontal wall defining a generally flat, substantially horizontal, load-supporting surface, said integral, generally flat walls further including an outer, substantially vertical wall and an inner, substantially vertical wall, the substantially vertical walls extending below the upper wall, being substantially parallel, and being spaced horizontally from each other by at least the width of the upper, substantially horizontal wall, the substantially horizontal wall and substantially vertical walls forming an inverted channel opening downwardly, said integral, generally flat walls further including an inclined wall extending below the outer, substantially vertical wall, the inclined wall defining a generally flat, indicia-receiving surface facing outwardly and downwardly from the front portion of said storage rack so as to be readily visible from the aisle when a pallet load is supported on said support beam, said indicia-receiving surface being inclined at a fixed angle in a range from about 10°
- to about 80°
relative to a vertical plane, said support beam having a lowermost edge, said indicia-receiving surface extending to the lowermost edge.

Abstract
A support beam for a storage rack has a tubular profile, which defines a ledge opening upwardly and inwardly, and which defines a generally flat, indicia-receiving surface facing outwardly and either downwardly or upwardly at an angle from about 20° to about 70° relative to a vertical plane. Alternatively, the tubular profile may define two such surfaces defining an obtuse angle relative to each other, namely an upper surface at an angle from about 20° to about 45° relative thereto and a lower surface at an angle from about 45° to about 70° relative thereto, or a generally arcuate, indicia-receiving surface having a suitable measurement. The indicia-receiving surface enables a person who is standing, or who is sitting on a lift truck, to have a generally perpendicular line of sight to such surface. The support beam may also be used in combination with a properly positioned fire extinguishing device to extinguish a fire in a supported load. When the fire extinguisher is activated, the fluid that is discharged impinges off the indicia-receiving surface, which may be inclined or curved, and onto the load.
