A shelf assembly for a refrigerator compartment such as a refrigerator for food products includes a shelf member slidably supported for extension and retraction on a shelf support. The shelf member includes side members which are preferably molded as a rim on an article support surface from an ethylene-polypropylene copolymer and include slide surfaces engaging spaced, generally horizontal and parallel shelf support surfaces preferably formed by L-shaped brackets on the shelf support. A guide member depends from at least one, and preferably both, of the side members to guide the sliding movement. A stop on the guide member limits travel by engaging a limit surface on the shelf support. The guide member and stop may be molded integrally with the side members to define a molded slide channel or formed by a rigid insert embedded in the rim during molding. The method includes injecting the moldable around a rigid core positioned in a mold cavity and withdrawing the core after removing the molded rim to leave a slide channel in the rim.

[ The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:] [1.] A shelf assembly for a refrigerated compartment comprising:a shelf support including a pair of spaced, generally horizontal, generally parallel, shelf support surfaces, a guide surface on each shelf support surface extending at an angle to said shelf support surface, an undersurface beneath each shelf support surface, and at least one mounting member adapted to mount said shelf support in a refrigerated compartment;a shelf member slidably mounted for extension and retraction on said shelf support, said shelf member including an article support surface and a pair of spaced side members, said side members being molded in one piece on said article support surface from a moldable material and extending along opposite sides of said article support surface, each side member including a slide surface slidably engaging one of said shelf support surfaces, at least one of said side members having a depending guide member adjacent said slide surface to guide sliding movement of said shelf member, said one guide member including a stop thereon, said guide member extending along said guide surface to limit lateral movement of said shelf member with respect to said shelf support, said guide member also including a laterally extending, lift restraining member, said lift restraining member extending under and immediately adjacent said shelf support undersurface and adapted to engage said undersurface in the event said shelf member is lifted to restrict vertical movement of said shelf member with respect to said shelf support; andsaid shelf support also including an elongated opening for receiving and allowing movement of said stop when said shelf member is slidably extended or retracted, and at least one limit surface for engaging said stop member to limit at least one of the extension or retraction of said shelf member.
