  • Patent number: 3936023
    Abstract: A light holder for releasable attachment to an overhead member, such as a rail associated with the grid system of a suspended ceiling. The light holder includes a pair of elongated support members which are fixed together adjacent corresponding one ends thereof. A pair of oppositely facing clips are provided adjacent said one ends of the support members, which clips are adapted to engage the flanges of an overhead rail. The support members are provided with a further pair of oppositely facing clips adjacent the opposite ends thereof. The opposite ends of the support members are normally positioned closely adjacent one another, but can be resiliently deflected outwardly to separate the further clips to permit positioning of an overhead rail therebetween. Release of the opposite ends of the support members, causes the further clips to be moved inwardly into clamping engagement with the flanges of the rail.
