Abstract
Abstract A one-piece lamp shade construction that is capable of being manufactured in a wide variety of styles. The lamp shade has a circumferential framework of wire mesh or perforated sheet stock and a layer of plastic forming the body of the shade. The plastic is molded from the inside of the pre-formed framework and extends through the openings in the framework thereby joining the framework to the plastic body. The invention is concerned with the lamp shade construction and method.
