Abstract: A lamp reflector comprises a pre-formed member molded from a polymer into a smooth and continuously curved shape. The members have a rigidity characteristic sufficient for maintaining its shape. A reflecting layer is bonded directly to the molded member to provide a reflector surface without facets or sharp angles. The shape of the member is comprised of a rear portion being an involute spline and side portions being defined by conic sections. The method of providing such a reflector decreases the amount of light reflected back into the lamp and trapped or absorbed within the lighting fixture. The method further eliminates the need for adhesive layers between the metal reflecting layer and the substrate which generally decreases the optical efficiency of the luminaire.

Abstract: An umbrella includes a hollow tubular handle, a hub slidably contained in the handle between an upper extended position and a lower stored position; a spider hinge mounted on the hub and including radially extending spider arms; a plurality of flexible struts, each having a fixed end and a free end, with each strut having a width which tapers from the fixed end to the fre end and with the fixed end being secured on each spider arm; a retainer bushing and plug which fixedly secures the spider hinge onto the hub; each strut further having a block thereon with an outwardly radially extending opening; a cord extending peripherally about the umbrella and connected within the openings of the blocks and thereby to the struts for applying a pre-loading tensioning force to the struts so as to bend the struts into a bowed configuration; and a one-piece web of flexible, water-resistant material connected to the ends of the tensioned struts.
