发明名称 Suspended ceiling electrical bracket
摘要 A suspended ceiling electrical bracket for installation in a grid type suspended ceiling to provide a means for mounting one or more rectangular junction boxes (24) or mounting a single octagonal junction box (48), to which can be installed in such boxes, electrical devices such as electrical outlets, security cameras, emergency lighting, exit signs, and ceiling fans. The invention comprises of a flat rectangular shaped base (10) and upwardly bent lip (12) made of rigid sheet metal which replaces a portion of ceiling tile (28) and is adapted to overlap and mount flush against three adjoining grid elements (26), while allowing three u-shaped hooks (14, 16, and 18) to fit over and be secured to the vertical flanges of the respective grid elements (26). Holes (12A and 12B) are made in the lip (12) and top portion of two hooks (16 and 18), to allows the attachment of cable or chain to the building's structural members that reside above a suspended ceiling. Near the side opposite the lip (12 ), spans a support angle (20) which is rigidly attached to the base (10), and has a vertical side to which the reinstalled remaining portion of ceiling tile (28) can rest flush against. The central portion of the flat base (10) comprises of one or more punched cutouts along with support means by which can be mounted one or more rectangular junction boxes (24) or a single octagonal junction box (48).
