The present invention relates to a fixture and a ceiling-mounted lighting fixture used for disposing a fixture body above a ceiling.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there is known a ceiling-embedded lighting fixture in which a fixture main body is embedded and arranged behind a ceiling using a fixing metal (for example, see Patent Document 1).
[0003]
In the lighting apparatus described in Patent Document 1, a pair of ceiling contact portions of the fixing fittings are firstly provided with fixing fixtures connected to both ends of a fixture body having an elongated box structure. The instrument body is inserted into the instrument mounting hole until the instrument body hits the lower surface of the hole edge, and the instrument body is suspended by, for example, a suspension bolt hanging from the ceiling. Thereafter, a reflector having an open bottom surface is arranged and attached below the fixing bracket.

[Problems to be solved by the invention]
However, the fixing fitting described in Patent Literature 1 has a vertical rising portion, and the ceiling contact portion and the metal fitting main portion are each bent at a right angle. The distance between the corners and the length of the main part of the bracket are formed to be substantially equal. Since it may hit the edge of the appliance mounting hole, there is a concern that the operation of attaching the appliance main body to the ceiling may not be easy.
[0006]
Further, as a method for solving this problem, a configuration in which the rising portions are inclined so that the distance between the rising portions becomes smaller as approaching the fitting main portion may be considered, but both ends of the metal fitting main portion are made. If the rising part is provided continuously inclined from the part, the separation dimension between the corners formed by the ceiling contact part and the rising part is likely to vary, and when the fixing bracket is inserted into the fixture mounting hole. There is a possibility that a part of the rising portion may come into contact with the appliance mounting hole, or the ceiling contact portion may not be properly hooked on the ceiling surface.
[0007]
Further, in the case of manufacturing a plurality of the fixing brackets as described above, manufacturing a configuration in which a rising portion is continuously provided by bending from both end portions of the metal fitting main portion is an angle formed between the ceiling contact portion and the rising portion. There is also a problem that it is complicated to suppress the variation in the separation dimension between the parts, and particularly in a configuration in which both rising portions are inclined, it is very complicated to suppress the variation.
[0008]
The present invention has been made in view of the above, and it is possible to improve the workability of mounting the instrument body, to suppress variation between products when manufacturing a plurality of products, and to easily manufacture each product. An object of the present invention is to provide a fixture and a lighting fixture.
[0009]
[Means for Solving the Problems]
The fixing bracket according to claim 1 includes: a metal fitting main part connected to an equipment main body inserted into an equipment mounting hole opened in a ceiling; and a slanting diagonally downward from both longitudinal ends of the metal fitting main part. A pair of inclined portions provided by bending; a rising portion provided by being bent downward from each of the inclined portions so as to be substantially perpendicular to a longitudinal direction of the main portion of the fitting; and a main portion of the fitting continuing from each of the rising portions. And a pair of ceiling contact portions provided in a direction parallel to the longitudinal direction of the portion and protruding outward.
[0010]
According to the present invention, first, a pair of inclined portions that are inclined obliquely downward from both ends of the metal fitting main portion connected to the appliance body inserted into the appliance mounting hole opened in the ceiling are formed. Next, a pair of rising portions is formed in a direction substantially orthogonal to the longitudinal direction of the metal fitting main portion so as to be continuous from each of the inclined portions. Then, a pair of ceiling contact portions is formed in a direction parallel to the longitudinal direction of the metal fitting main portion so as to be continuous from each rising portion and project outward.
[0011]
According to the present invention, since the main part of the fitting initially inserted into the fitting hole is narrower than the fitting hole, it is easy to insert the fixing fitting into the fitting hole when the fitting body is provided on the ceiling. Thus, it is possible to prevent the corner formed by the inclined portion and the main part of the metal fitting from being caught in the equipment mounting hole, thereby improving the mounting workability of the equipment main body.
[0012]
Further, since the metal fitting main portion, the pair of inclined portions, the pair of rising portions, and the pair of ceiling contact portions are formed by continuous bending, manufacturing of the fixing metal can be facilitated. Furthermore, when manufacturing a plurality of fixing brackets, the dimension between the pair of ceiling contact portions, which are required to have the highest dimensional accuracy, is by interposing an inclined portion between the bracket main portion and the rising portion, Since the dimensional accuracy can be easily increased, it is easy to suppress variations between products.
[0013]
The lighting fixture according to claim 2 is a fixture main body inserted into a fixture mounting hole opened in a ceiling; a fixture according to claim 1 fixed to the fixture main body; and a fixture below the fixture by covering the fixture mounting hole. And a reflector disposed on the side.
[0014]
