Plastic box for ceiling fan support
First Claim
1. A ceiling box adapted to support a ceiling fan thereon and adapted to be mounted on a structural member, the combination comprising:
- a body member having a lower wall and first and second opposed side walls defining a recess for receiving the structural member therein;
first means, formed in said lower wall, for receiving a first box mounting fastener therein;
second means, formed in said lower wall, for receiving a second box mounting fastener therein, said first and second means being located at opposite sides and ends of said lower wall;
third means, formed in said body member adjacent said first means, for receiving a first fan supporting fastener therein; and
fourth means, formed in said body member adjacent said second means, for receiving a second fan supporting fastener therein,said ceiling box being integrally formed of substantially rigid plastic.

Abstract
A plastic ceiling box adapted to support a ceiling fan thereon and adapted to be mounted on a structural member, such as a ceiling joist. The ceiling box comprises a body member having a lower wall and a pair of side walls defining a recess for snugly receiving the ceiling joist therein. Box mounting holes for receiving box mounting fasteners are located at opposite sides and ends of the lower wall for attaching the ceiling box to the joist. Openings for receiving fan supporting fasteners are formed in the body member adjacent the box mounting holes. Brackets at opposite ends of the body member aid in attaching the body member to the joist. This overall arrangement provides sufficient support and strength to resist dynamic loads of a ceiling fan even though the ceiling box is formed of plastic.

14. A plastic ceiling box adapted to support a ceiling fan thereon and adapted to be mounted on a ceiling joist, the combination comprising:
-
a substantially planar lower wall having means for mounting said ceiling box to the ceiling joist; first and second substantially planar opposed side walls coupled to and substantially perpendicular to said lower wall for defining a joist receiving recess sized to snugly receive a ceiling joist therein; an outer wall structure coupled to said first and second side walls and said lower wall for defining a substantially U-shaped inner cavity with a continuous bottom edge defining an open bottom; a first bracket being coupled to said outer wall structure to form a first substantially planar surface with said first side wall for contacting one side of the ceiling joist; a second bracket being coupled to said outer wall structure to form a second substantially planar surface with said second side wall for contacting the other side of the ceiling joist; and fastening means, coupled to said outer wall structure at said bottom edge, for coupling the ceiling fan thereto. - View Dependent Claims (15, 16, 17, 18, 19, 20)
