In addition, although it is not a particularly essential component of this invention,
In this embodiment, the flange receiver is a metal fitting 38 as shown in FIG.
and Fransilogold 39 are used.

The metal fitting 38 of the flange receiver is formed of a thin sheet metal into a cylindrical shape with a bottom, and a roll screw is formed on the peripheral wall as shown in FIG.

In addition, as shown in Fig. 6, there is an intermediate holder 1 in the center of the bottom plate.
A circular hole (
The inner diameter F) 40 is small, and there are small holes 4 on both sides of the circular hole 40.
1 a and 41 b are formed, respectively.

Furthermore, the circular hole 40 extends from the bottom plate portion to the upper end of the peripheral wall portion.
A communication path 42 is formed which communicates with the.

The width dimension of this communication path 42 is made to match the width dimension C of each communication path 22.31 of the hanging fitting 15 and the intermediate holder 15.

The Franshiro gold 39 is formed of a thin metal plate into a cylindrical shape, and the flange receiver has a roll screw formed on the outer periphery of the lower end as shown in FIG. A flange portion 43 is formed.

The decorative cover 7 is attached to the lower surface of this flange portion 43.
The lower end of is the mounting point.

Next, a method of attaching the jump rear 1 to the ceiling surface 2 using this lighting fixture attaching device 13 will be explained.

First, the hook ceiling main body 9 is attached to the ceiling surface 2, and a pair of mounting arms 12a,
12b is made to protrude horizontally.

In addition, the cord of the chantrier 1 is inserted into the support tube 16 from the lower end side, and the hook sealing lid 10 is connected to the insertion end, and the lower end of the support tube 16 is fixed to the lamp body 3 of the jump rearer 1. A locking body 17 is fixed to the upper end of 16 by screwing.

Therefore, the mounting arms 12 a , 12 b are inserted into the through holes 24 a , 24 b of the hanging metal fitting 14 , and the hanging metal fitting 14 is attached.
After suspending the intermediate holder 15 from the sealing body 9, insert the cylindrical holding part 28 of the intermediate holder 15 into the circular mounting hole 19 of the hanging metal fitting 14 from above, and attach the intermediate holder 15 as shown in FIG. 7a, l). The notch surfaces 34 a and 34 b of the hanging fitting 14 are made to face the bent edges 27 a and 27 b of the hanging fitting 14, and the communicating passages 22 and 31 of both are made to overlap.

In addition, the flange receiver connects the metal fitting 38 to the mounting member 2 of the hanging metal fitting 14.
5 a and 25 b using the small holes 41 a and 41 b and the threaded holes 26 a and 26 b. position it below.

At this time, the annular protrusion 35 at the lower end of the intermediate holder 15 fits into the circular hole 40 of the flange receiver 38 as shown in FIG.
The intermediate holder 15 is positioned.

Then, after inserting the decorative tube 8 and the Franshiro gold 39 to which the decorative cover 7 is fixed to the outside of the support tube 16,
The locking body 17 is attached to the Okima holder 15 in the state fixed to the support tube 16 in the following manner.

That is, the sealing lid body 10 and the locking body 17 are inserted into the inside of the hanging metal fitting 14 through the large opening 21 of the hanging metal fitting 14, and the support tube 16 is inserted into the communication path 42, 22, 31.
is introduced into the center hole 30 of the intermediate holder 15 through the middle holder 15, and one arc-shaped elongated hole (for example, 37a) of the locking body 17 is fitted into the positioning protrusion 32 of the intermediate holder 15 from above. Place it on the top surface.

At this time, the locking body 17 is rotatably held inside the positioning edge 33 and prevents the support tube 16 from being pulled out from the intermediate holder 15.

As shown in FIG. 8, the rotation amount of the locking body 17 is approximately 45 mm due to the engagement between the circular arc-shaped elongated hole 37a and the positioning protrusion 32.
It will be limited to a range of °.

In this state, the sealing cover 10 is engaged with the sealing body 9 to establish an electrical connection.Next, when the flange cover 39 is screwed into the flange holder 38 from below, the upper edge of the decorative cover 7 comes close to or in close contact with the ceiling surface 2, and the installation of the chanterrier 1 is completed.

Further, even after being installed in this manner, the jump rear 1 can be rotated together with the locking body 17 within a range of about 45 degrees, and the installation direction can be easily corrected.

Incidentally, in order to remove the chanter rear 1 from the ceiling surface 2 in the event of a malfunction of the jump rearer 1 during use or damage to the lamp cover 6 or the like, the procedure for attaching the chanter rear 1 described above may be reversed.

FIG. 9 shows a modification in which the flange receiver is installed without using the metal fittings 38 and the flange metal fittings 39, and the decorative tube 8 is also not used. A decorative nut 44 is prepared, and the lower end of the decorative cover 7' is held between this decorative nut 44 and the lower surface of the central horizontal plate portion 18 of the hanging metal fitting 14.

The lighting equipment mounting device of the present invention described in detail above has the configuration described in the above-mentioned utility model registration claims, so it uses a hook ceiling and a pair of mounting arms protruding from the hook ceiling body. For hanging metal fittings,
The locking body fixed to the upper end of the hook sealing lid and the support tube can be inserted through the large opening, and the locking body is simply placed on the top surface of the intermediate holder and is not restricted from upward movement. , and the support tube can be inserted and removed through the central hole of the intermediate holder through a communication path narrower than the large opening, making it easy to mount the lighting fixture on a mounting surface such as a ceiling. Since it is removable, it is easy to attach and detach during construction or repair, and its practical effects are great.

Coupled with this ease of attachment and detachment, the weight of the lighting fixture is transferred through the support tube, locking body, intermediate holder, hanging bracket, and hook ceiling body with a pair of mounting arms. Since the cord is supported on the mounting surface, the weight of the appliance does not act on the cord, which is advantageous for use in heavy lighting appliances such as jump rear lights.

Furthermore, since the locking body that prevents the support tube from being pulled out downward from the intermediate holder can be rotated horizontally with the support tube relative to the intermediate holder, the lighting fixture can be installed later. The mounting of the fixture has the advantage of being able to correct direction, and this is another reason why it is suitable for use in lighting fixtures such as chantilliers and the like.

Moreover, the cord connecting the lighting fixture and the hanging ceiling lid can be passed through the support pipe, and the hanging ceiling lid can be freely inserted into the large opening of the hanging fitting as described above, and both side plates of the hanging fitting can be inserted. Because a hook ceiling is placed in between,
The cord does not touch the hanging fittings.

Therefore, there is an effect that the cord is not damaged by the edges of the hanging fitting.
