ABSTRACT:
A shelving system includes a pair of upright frames with a plurality of shelves connected therebetween, each upright frame including a pair of vertical posts with a plurality of braces extending between the posts to form rigid frames. Each post is generally U-shaped, with each brace having an end journaled within the U-shaped frame, and removably secured utilizing a plurality of protrusions engaged within apertures in a leg of each post. Each brace has a width which is effective to snugly secure the brace between the legs of each post. Each end of each brace has an upper and lower protrusion with a ramped distal portion for separating the legs of the post as the brace is inserted between the legs of the post. A proximal flat face on each protrusion engages a straight edge of each aperture to resist removal of the brace end from the post. The distance between the proximal flat face of each protrusion and the end of each brace is substantially the same as the distance between the web of each post and the flat distal edge of each protrusion, such that each brace end is securely engaged with the end of the brace in contact with the web of the posts and the protrusion proximal flat faces in engagement with the aperture edges. Vertical movement of each brace is resisted by use of a central protrusion on the ends of each brace located between the upper and lower protrusions, having flat upper and lower faces in engagement with straight edges of a central aperture on each post. In addition, vertical movement is resisted by the use of flat horizontal faces on the upper and lower protrusions which engage straight edges on the upper and lower apertures.
