CA 2541640

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. Another aspect of the invention is the tube half clamp, which can provide quick assembly and infinite positional placement on a horizontal or vertical pipe member of a scaffolding system.

La présente invention concerne la fourniture d'un support d'éclairage temporaire pour échafaudage. Le support comprend deux composants principaux et les dispositifs de fixation nécessaires pour monter les boîtiers d'éclairage et les montants prévus dans deux configurations. Le support consiste en un premier tube à parois minces pourvu d'une demi-bride soudée à une extrémité et en un raccord en té à parois minces soudé à l'extrémité opposée. La bride et le té sont orientés de manière à optimiser le positionnement précis du support. Un second tube à parois minces est fixé à la pièce en té, perpendiculairement, de manière à former un cadre à angle droit. Le second tube est maintenu perpendiculairement au premier tube au moyen de deux bagues à rondelle soudées au-dessus et au-dessous du raccord en té, lequel maintient fermement les deux tubes l'un contre l'autre. Un petit espace aménagé entre la bague et le raccord en té permet au second tube de pivoter librement en rotation. Les cordons intégrés au support sont directement attachés à l'échafaudage pour des raisons de sécurité. Un autre aspect de l'invention concerne la demi-bride de tube, qui offre une possibilité d'assemblage rapide et une multitude de possibilités de positionnement sur les structures tubulaires horizontales ou verticales de l'échafaudage.
