Method for making a sliding refrigerator shelf assembly

摘要

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.
