In the structure shown in FIG. 9, an electrical connection is made to a hanging ceiling body 101 mounted on the ceiling by a hanging sealing cap 102. 103, the hooking ceiling 101,
102 is performed separately. More specifically, the insertion hole 10 through which the hooking sealing body 101 can be passed.
4 is fixed to the ceiling 111 with a wood screw 110. Next, the hooking sealing body 10
1 and a hooking sealing cap 102 is attached thereto for connection, and a flange cover 106 covering the hooking ceilings 101 and 102 is attached to a mounting bracket. In this mounting method, a plurality of screws 105 provided on the mounting bracket 103 are passed through a flange cover 106 and fastened with a decorative nut 107. A lighting fixture body (not shown) is suspended from the flange cover 106 via an eye nut 108 and a chain 109. A power supply line 112 extending from the hooking sealing cap 102 extends along the chain 109 from inside the flange cover 106 through the inside of the eye nut 108 to a lighting fixture main body (not shown).

In this mounting structure, a plurality of wood screws 1
10, the mounting bracket 103 is attached to the ceiling 111 surface, and a plurality of decorative nuts 107 are used to mount the flange cover 1 on the ceiling 111.

It has been pointed out that it is inclined with respect to the surface, and a gap is easily generated between the ceiling 111 surface and the flange cover 106. In addition, the directionality (horizontal rotation angle) of the lighting equipment greatly affects the layout and design of the room, and if lighting equipment is installed in two or more places, the orientation must be the same. Is desired, but after installation, the user may feel that the directionality of the lighting fixture is deviated. In such a case, the flange cover 106 is removed, the wood screw 110 is loosened, and the direction of the mounting bracket 103 is changed according to another direction (horizontal rotation angle).
Again, it becomes necessary to retighten the wood screw 110 using a tool such as a screwdriver.

FIG. 6 is an enlarged cross-sectional view of a main part of a lighting fixture mounting structure according to another embodiment. FIG. 6A shows a structure using a rectangular hooking sealing body as a hooking sealing body. B) shows a structure using an embedded hanging rosette as a hanging sealing body. There are several different heights of the hooking sealing body, such as a tall rectangular hooking sealing body and a low height hooking rosette. Specifically, in the rectangular hooking sealing body 1 of (A), the height is 22 mm, and (B)
The height of the embedded rosette 10 is 11 mm, and the height difference is 11 mm. In the mounting structure of this embodiment, the flange cover 6 is
11, the screw structure 61 attached to the hanging sealing cap 1 is the embedded hanging rosette 10 shown in (B), which is the minimum length required for screwing from the flange cover 3. The length is set so that about 10 mm appears. Thereby, (A)
In the case of the rectangular hooking sealing body 1 having a height of 22 mm as shown in FIG.
It will come out 1mm. Accordingly, the screw member 7 such as a decorative nut to be attached to the screw structure portion 61 is also set to have a completely threaded portion with a depth of 21 mm or more, so that the ceiling 111 has two different heights of the hooking sealing body. It is possible to correspond to. Thus, the screw structure 61
Is equal to or greater than the sum of the difference in height and the length required for screwing so as to correspond to several types of hooking sealing bodies 1 and 10 having different heights. By doing so, it can be used commonly for several types of hooking sealing bodies.

As described above, in the mounting structure according to this embodiment, the length of tightening the decorative nut may be 20 mm or more. Therefore, at the time of removal, it is necessary for the user to keep turning the screw member 7 such as a decorative nut in a state where the user cannot recognize when the screw comes off. in this way,
When the removal operation takes a longer time than usual, a situation in which the screw member 7 such as the decorative nut comes off the screw structure portion 61 when the user is not aware of the moment when the decorative nut comes off may be considered. In that case, it is conceivable that the screw member 7 such as a decorative nut cannot be received and is dropped. Therefore, it is important for the user to recognize the moment when the screw member 7 comes off in order to prevent the screw member 7 from dropping. Therefore, as shown in FIG. 7A, a coloring portion 66 is provided at the lower end portion of the screw structure portion 61 in the support shaft 6 of the hooking sealing cap 2. Thereby, it is possible to make the used winding recognize that the terminal end of the screw is near, and call attention. Also, from the same meaning, FIG.
As shown in (B), the user can also recognize the tip of the screw by a method in which a notch 67 is provided at the tip of the screw structure 61. As in these examples, it is also preferable to implement a means for recognizing the approach of the screw tip to the user.

From the above situation, it is conceivable that the screw member 7 falls at the moment when the screw member 7 comes off. As a method for preventing such a situation, it is preferable to provide the screw member 7 with a fall prevention means. . FIG. 8 shows an example of the fall prevention means. One end of a connecting member 72 such as a string (a string, a chain or a wire) is attached to the screw member 7 so as not to hinder the rotation of the screw member 7 from being tightened. The other end is attached to the flange cover 3 so that it can be stored. In this case, it is effective not only to prevent the screw member 7 from dropping but also to prevent the screw member 7 from being lost.

Further, although not shown, as another drop prevention means, the screw member 7 is provided with a magnetic force that does not drop even if it comes off the screw structure portion 61, thereby screwing the screw portions together. Even in a state in which the screw member 7 is not provided, a method of creating a situation in which the screw member 7 itself is attached to the support shaft 6 made of iron or the like, and a method of preventing the screw member 7 from falling can be considered. In this case, even if the magnetic force is applied, the magnetic force is set to such a degree that the user can easily remove the magnetic force. It is sufficient that at least one of the screw member 7 and the support shaft 6 is provided with a magnetic force, for example, the support shaft 6 is provided with a magnetic force, and the two are attached by the magnetic force.

In addition to the above embodiments, the present invention can be implemented with various modifications. For example, a male screw is formed on the screw member 7 and a female screw is formed on the support shaft 6. It may be. In addition to the screw, a fixing member using elastic resistance such as a claw or a fixing member as a cylindrical body, a screw is provided in a direction intersecting the axis of the cylindrical body,
It is also possible to change the support shaft to the one fixed by pressing with the screw. Further, the support shaft 6 may be directly attached to the hooking sealing cap 2. Further, the support shaft 6 is formed into a cylindrical body through which the power supply line 8 can pass, and a passage for passing the power supply line 8 is also provided in the fixing member (screw member 7) to fix the support member 6 (screw member 7). The power supply line 8 may be drawn from the outside. Alternatively, the lighting fixture body 9 may be passed through the support shaft 6 and supported by a fixing member (screw member 7). Instead of fixing the upper end 32 of the flange cover 3 in contact with the ceiling 111 surface, the upper end 32 of the flange cover 3 may be fixed with a gap provided between the upper end 32 of the flange cover 3 and the ceiling 111 surface. .
