Metal Pallet Racking

A metal pallet racking of the vertically adjustable type having at least four rectangularly

spaced vertical support posts, a plurality of pairs of horizontal shelf beams detachably mounted on the posts by means of post-to-beam connectors, and a plurality of stamped steel metal hook elements integrally attached to each post-to-beam connector, the hook elements being detachably engageable with a vertical series of keyhole shaped apertures in the front wall of each post, each such keyhole shaped aperture having a minimum lateral dimension substantially greater than the gauge of the sheet metal of said hooks.

The present invention relates to metal pallet racking of the vertically adjustable type finding particular but not exclusive utility in warehouses and supply depots. More particularly, the invention relates to an improvement over the prior pallet racking disclosed in U.S. Pat. Nos. 2,925,920 and 3,142,386 issued Feb. 23, 1960 and July 26, 1964, respectively, on the application of Leroy F. Skubic. One form of such prior rack is currently marketed by The Paltier Corporation, of Michigan City, Ind., under the designation "Series 3200 Standard Pallet Rack".

The present invention represents an improvement over still another prior pallet racking which is also currently marketed. This prior rack bears some similarity to the prior racks just mentioned but utilizes different vertical posts and post-to-beam connectors. The posts are formed with relatively wide keyhole shaped apertures which slidingly interfit with headed studs on the post-to-beam connectors. The connectors themselves abut against the outer walls of the vertical post and may utilize a separate locking means to preclude disengagement. These post-to-beam connections do not permit the substantial horizontal pivotal movement of the prior racks discussed above in event of horizontal displacement of the post due to accidental impact. Although this type of rack is supplied with overall dimensions relatively close to those of the other prior racks mentioned above, their components are not interchangeable.

It is, accordingly, an object of the present invention to provide a vertically adjustable pallet racking with post-to-beam connectors having stamped sheet metal hooks, the components of which rack will be interchangeable with those of prior racks having relatively wide keyhole shaped apertures which slidingly interfit with headed studs on the post-to-beam connectors.
