Abstract
An all plastic shelf is part of a shelving system and is provided for uses where metal shelves might rust or corrode, especially if attacked by hostile chemicals. The underside of the plastic shelf has a channel formed around the periphery thereof. A welded metal frame fits into the channel, with either the width of the frame or a cover plate substantially covering the channel in order to prevent an entry of foreign matter therein. Sockets are formed in the corners of the frame to receive corner posts for supporting the shelf. These sockets fit into corner sockets which are molded into the metal frame.
Claims22
A shelf for a rack of shelves which are supported by at least two corner posts, each of said corner posts provided with a plurality of recesses spaced at intervals along the length of said posts, a plurality of sleeves for receiving said corner posts, each of said sleeves having an internal passageway complementary in shape to said corner posts whereby said sleeves may slide longitudinally along said posts, detent means formed on the inside of said passageway of each of said sleeves for cooperating with said recesses whereby said sleeves may be held in place on said posts by said detent means fitting into a selected one of said recesses, comprising a molded or formed all plastic shelf having a surface and having at least one peripheral open channel formed therein and on the underside therof, said channel opening to the exterior of the shelf surface, plastic sockets molded into at least two corners of said shelf for receiving said corner posts, metal reinforcing members inserted within said channel through said channel opening, a plurality of metal sockets disposed in said plastic sockets for receiving and capturing said sleeves when said sleeves are held in place on said posts.
A shelving system of all plastic shelves having corners with corner post receiving sockets formed therein;
- corner posts with a plurality of capture means formed periodically along the length thereof for engaging and securing said shelf in place at a desired position on said posts;
- keeper means for mating with said capture means and adapted to fit around said corner posts and to engage said shelves and to secure the shelves in place on said posts at selected ones of said capture means;
- comprising a plurality of shelves being made of molded or formed plastic, each of said shelves having at least one channel extending peripherally along the edge of said shelf and terminating in said corner sockets which are attached to said shelf;
- a metal frame having side rails disposed in said channel;
- and a plurality of metal sockets attached to said side rails and disposed in said molded or formed corner sockets, the metal sockets of said metal frame being shaped and dimensioned to receive and hold said keeper.
A shelf for a rack of shelves which are supported by at least two corner posts, each of said corner posts provided with a plurality of capture means formed periodically along the length thereof for engaging and securing said shelf in place at a desired position on said posts, a plurality of keeper means for mating with said capture means and adapted to fit around said corner posts to secure said shelves in place on said posts, comprising a molded or formed all-plastic shelf having a surface and having at least one open peripheral channel formed therein and on the underside thereon, said channels opening to the exterior of the shelf surface, plastic sockets molded or formed into at least two corners of said shelf, metal reinforcing members inserted within said channel, said members comprising a metal frame formed from a plurality of side rails each of which includes a transverse flange disposed along the bottom of said rail and positioned to extend across the opening in said channel thus tending to seal the channel against any entry of foreign matter, and a plurality of metal sockets disposed in said plastic sockets for receiving and holding said keepers when said keepers are mated with said capture means.
