BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting fixture suspender for suspending a lighting fixture.

[0002]

2. Description of the Related Art Conventionally, lighting fixtures, such as spotlights, which hang from a ceiling surface for illumination have been used. As a method of installing this lighting fixture on the ceiling surface, for example, FIG.
The installation hole 46 through which a hanging bolt a as a rod-like installation member provided to be suspended from the ceiling as shown in FIG.
1 and 461 on the upper surface, the hanging tool main body 46 having two on the upper surface is fixed to the hanging bolts a by using nuts, so that the ceiling surface b
Then, a hanging pipe 42 to which a lighting fixture is fixed is hung on the hanging tool body 46 to be installed.

A portion of the hanging tool main body 46 where the hanging pipe 42 is hung is provided so as to protrude toward the hanging pipe 42 side.
2 is provided with a hanging hole 463 for hanging. Further, two mounting holes 4 are sandwiched between the projecting pedestal portions 462.
61 and 461 are provided so that the weight of the lighting fixture and the like is not biased toward the ceiling surface b. But,
In such a hanging tool, the hanging bolts a are used to install the mounting holes 461 and 461 of the hanging tool.
It is necessary to provide two bolts by adjusting according to the interval of 461, there is a problem that there are many man-hours required to install the hanging bolt a, and it is necessary to fix nuts at two places to install the hanging tool, There was a problem that workability was low.

[0004] For this reason, as shown in FIGS. 7 (a) and 7 (b), a hanging tool which is formed so as to be locked to one hanging bolt a and fixed to a ceiling surface b has been studied. The hanging tool includes a hanging pipe 52 formed so that the lighting fixture can be fixed thereto, a pipe receiving tool 54 formed such that the hanging pipe 52 can be hung,
And a hanging tool main body 56 having one installation hole 561 on an upper surface through which the hanging bolt a can be inserted. The hanging tool main body 56 is provided on an axial extension of the hanging bolt a. By arranging the pipe 52, the weight of the lighting equipment and the like is not biased toward the ceiling surface b.
It should be noted that the hanging member main body 56 of the hanging member includes a pipe receiving member 54.
A pedestal portion 562 is provided so as to protrude toward the suspension pipe 52, so that the pipe receiver 54 can be easily mounted.

As shown in FIG. 7 (b), when the hanging tool is fixed to the ceiling surface b, the hanging bolt a is disposed in the pipe receiving tool 54. By making the portion concave on the side of the suspension pipe 52, the pipe receiving member 54 or the suspension pipe 52 does not contact the suspension bolt a, and a complicated bending process is performed. However, the pipe holder 54 subjected to such a complicated bending process has low productivity in terms of manufacturing,
There is a need for a lighting fixture hanger that can be attached using a pipe holder 54 manufactured with a small number of bending processes.
