Title: Hook ceiling body
Inventor: UEDA KO
IPC: F21Y103/02
Filed: 2000-03-09
Abstract: PROBLEM TO BE SOLVED: To provide a hook ceiling for allowing a stable mounting of a lighting fixture as well as less use of relatively expensive heat-resistant resin for a material cost reduction. SOLUTION: A hook ceiling body 41 is composed of an upper ceiling body 43 mounted on a surface 42 for mounting a lighting fixture for ceiling use and a lower ceiling body 44 mounted so that it is partially fit into the bottom of the upper body. The lower ceiling body 44 has a small diameter cylindrical part 48 at an upper part thereof. The weight of the lighting apparatus is therefore supported by the cylindrical part held in between with a metal hook on the lighting fixture side not shown. An outer circumference 45 of the upper ceiling body 43 has a larger diameter than that of the cylindrical part 48 and the metal hook is regulated to move upward. In addition, a n outer- circumferential claw 46 projecting toward the cylindrical part 48 beginning at the upper ceiling body 43 blocks the rotation of the metal hook. The above allows the stable mounting of the lighting fixture.  No other part than the lower ceiling body 44 requires the use of the expensive heat-resistant resin, thus allowing a reduction in the material cost.
