PUSH-BACK STORAGE RACK

A push-back storage rack comprises a frame (12) defining at least one storage bay (18) having a depth sufficient to accommodate a plurality of separate storage units (19); and a track-mounted carriage assembly mounted in the bay. The carriage assembly comprises at least two articulated carts (32) connected together end-to-end for pivotal movement about a transverse horizontal axis. The carts ride on a track (24) that has an upper track section (26), a lower track section (28), and an arcuate front section (30) that joins the upper and lower track sections. The track guides the carts for movement between the front and the rear of the bay on the upper track section and directs the carts downwardly and then rearwardly on the lower track section in an inverted position as the carts move forwardly at the front end of the upper track section. The carts are thus stored underneath the upper track section and are brought upwardly to the upper track section as the carts are filled and moved rearwardly in the upper track section.
