Patent number: 6267491Abstract: This invention discloses a lamp housing adaptable for snapped-in installation of the lens member. The interior wall of the housing is provided with an annular step and integrally formed raised projections which together form slots for receiving the peripheral edge of the lens member. The raised projections are shaped to facilitate the installation and retention of the lens. The lens member, made of resilient material, is of sufficient flexibility that it can be pressed past the raised projections and be lodged in the slots. A gasket is interposed between the lens member and the annular step. The slots are so dimensioned that the raised projections press against the lens and the gasket to retain the lens in the slots and additionally seal the interior of the housing from the outside environment.Type: GrantFiled: October 25, 1999Date of Patent: July 31, 2001Assignee: Grote Industries, Inc.Inventor: Albert Parrigin

Patent number: 6183116Abstract: Apparatus for use in retaining a lamp in a housing include a member having a central opening, a first sidewall facing the central opening, a substantially opposing second sidewall facing away from the central opening, a front wall extending between the first and second sidewalls and a substantially opposing back wall extending between the first and second sidewalls. A plurality of spaced apart through holes passing through the member from the front wall to the back wall are provided. Each of these through holes include joined first and second openings. The first opening is located closer to the first sidewall and the second opening is located closer to the second sidewall. These members are particularly useful in combinations in which a lamp is located at least partially in a lamp housing. A member, as noted above, is provided in close proximity to the lamp face, for example, by fastener assemblies, to reduce the risk of the lamp falling from the housing, for example, during extreme storm conditions.Type: GrantFiled: February 22, 1999Date of Patent: February 6, 2001Assignee: New Bedford Panoramex CorporationInventors: Kenneth J.
