Patents Assigned to Sumac Fabrication Company Ltd.
  • Patent number: 7566151
    Abstract: The present invention is concerned with providing a support for temporary lighting for use with scaffolding systems. The support assembly comprises of two main components and the required fastening systems to affix lighting fixtures and mast light fixtures embodied in two configurations. The support consists of a thin walled pipe with a tube half clamp welded to one end and a thin walled tee welded to the opposite end. The clamp and tee are orientated to provide the support with a precise mounting position. A second thin walled pipe is positioned concentrically through the tee to create framework that has an angled appearance. The second pipe is maintained annular and concentric to the first pipe by means of two washer type collars welded above and below the tee that constrains both pipes to each other. A small space between the collar and tee provides the second pipe with unconstrained rotational movement. Lanyards incorporated in the support are fixed directly to the scaffold for job site safety concerns.
