Abstract

Abstract A trouble light guard and reflector molded of plastic dielectric material for rapid mounting on a trouble light. The structure is molded in two halves hingedly joined at the top. One half comprises longitudinal and transverse spaced bars permitting the light to pass through. The other half comprises a reflector and is segmented into three angularly positioned panels. The open side is similarly angled. At the juncture, the plastic is pliable and acts as the hinge. At the outer ends, both halves are provided with integral arcuate sections adapted to surround a light socket. One arcuate section has an opening at each end and the other arcuate section has resilient hook members adapted to enter and lock in the openings to lock the guard to the light socket. A plastic hook is provided with a depending shank having a button end. The hinge portion is provided with a central opening having a slot for resiliency. The button end of the hook can be forced into the opening to lock in place. The entire structure is dielectric, light and strong.
