Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to lighting devices, and in particular to a simple mounting structure for a decorative flange cover that covers the ceiling mounting portion of a pipe hanging lighting fixture such as a chandelier.

Generally, hanging lighting fixtures such as chandeliers that also serve as indoor interior decorations have a connection cord covered with a pipe, and then a ceiling mounting bracket or a rosette attached to the ceiling and a ceiling at the end of the connection cord. The part is covered with a flange cover so that the mounting hardware and sealing are not visible from the outside. By the way, conventional flange covers are formed into a hemispherical shape large enough to sufficiently cover the mounting hardware, and are inserted into the pipe, with the opening on the large diameter side facing the ceiling. It was installed and fixed. However, it required installation work at a high position, had poor workability, and was unfavorable in terms of appearance. There is also a type in which the flange cover is divided into upper and lower parts, the lower cover is fixed to the upper part of a pipe or lighting fixture, and the upper cover is attached and fixed between this and the ceiling surface. This is done by providing an appropriate protrusion on the outer peripheral surface of the upper part of the lower cover, providing an L-shaped locking groove corresponding to the projection on the inner peripheral surface of the lower part of the upper cover, and inserting the protrusion of the lower cover into the locking groove of the upper cover. They are fitted, rotated relative to each other, and then engaged and fixed. However, although the above configuration allows the flange cover to be easily installed, the locking groove remains exposed to the outside, which is unfavorable in appearance, and also prevents the flange cover from absorbing dimensional errors between the lower cover and the ceiling surface. However, since it is necessary to fix the upper surface of the lower cover to the ceiling surface, the protrusion or locking groove must be formed at an angle, and forming it in this way is difficult, time-consuming, and increases the manufacturing cost. There were some drawbacks.

In view of these points, this invention provides a lighting device that can cover the ceiling-mounted part of a pipe-suspended lighting fixture with a flange cover in an elegant and simple manner.Examples will be described below with reference to the drawings. .

In Figures 1 to 4, 1 is a ceiling surface of a house, etc., 2 is a hook-type rosette fixed to the ceiling surface 1, and 3 is a ceiling hook that connects to the rosette 2 with a locking claw on the top surface. 4, 4' into the rosette 2 and hook it. Reference numeral 5 denotes a connection cord hanging down from the ceiling 3, which is connected to a lighting fixture 6 at the bottom. 7 is a mounting bracket fixed to the ceiling surface 1,
A rectangular notch 9 with one side open to the side end surface 8 is provided in the center, and the other side is bent downward to form a bent part 10, and U-shaped hook parts 11, 1 are provided at both ends.
1' is provided, and the rosette 2 is fixed to the ceiling surface 1 with screws so as to sandwich it therebetween. 12 is lighting equipment 6
The support arms 1 on both sides are used to suspend and support the
3, 13' are bent upward, and the tips thereof are bent outward, and a locking window is provided at the upper part of the support arm 13, 13' for locking the hook part 11, 11' of the mounting bracket 7. 14, 14', and pipe 1 in the center.
5 insertion holes 16 are provided. 17 is lighting equipment 6
The lower cover is made of synthetic resin and is fixed to the upper part of the instrument body 18, and has a two-tiered structure with a large diameter upper part and a smaller diameter lower part, and an insertion hole 19 for the pipe 15 is provided in the center of the lower surface. A guide cylinder 20 is integrally provided in the. Further, a vertical groove 21 which serves as a pattern and a guide during locking is provided in the vertical direction along the entire circumference of the upper part, and the corners of the outer peripheral edge of the upper end are shaved.
Reference numeral 22 denotes an upper cover made of synthetic resin that engages with the outer circumference of the upper part of the lower cover 17 and is pressed and fixed to the ceiling surface 1. The inner diameter of the lower opening is made slightly larger than the outer diameter of the upper part of the lower cover 17, and Pressing pieces 23, 23', 2 are provided at three locations on the circumferential surface upward from the lower end.
3" upright, each pressing piece 23, 23', 23"
Locking protrusions 24, 24', and 24'' are provided at the center of the locking plate, which successively protrude in the radial direction from the bottom to the top and have step-like locking protrusions with arcuate upper portions. Note that the flange cover is composed of an upper cover and a lower cover, and the number of locking protrusions can be changed as appropriate.

In the above configuration, the notch 9 of the mounting bracket 7 is fitted to the outer periphery of the rosette 2, and the hook portions 11, 1
1' on both sides of rosette 2, and screw 2
5 to attach and fix it to the ceiling surface 1. On the other hand, in the lighting fixture 6, the upper cover 22 is inserted through the pipe 15 fixed to the center of the upper surface of the fixture body 18, the guide tube 20 of the lower cover 17 is inserted, and then the insertion hole 16 of the support fitting 12 is inserted. , the nut 26 is screwed into the threaded part 15a formed at the upper end of the pipe 15 to integrate the instrument main body 18, the lower cover 17, and the support fitting 12, and the connection cord 5 is pulled upward through the pipe 15, and the tip is sealed. Install 3. In addition, after the lower cover 17 and the support metal fittings 12 are once attached to the instrument main body 18, the upper cover 22 is inserted in a state slightly inclined from above.
It may also be brought to the instrument main body 18 side. Then, hold the support fitting 12 and carry it upward, and
Locking windows 14, 1 provided on support arms 13, 13' of 2
4' is inserted into the hook portions 11, 11' of the mounting bracket 7, and the support arms 13, 13' are engaged with the hook portions 11, 11', after which the sealing 3 is attached and connected to the rosette 2. In this state, the upper cover 22 is lifted upward, the locking protrusions 24, 24', 24'' are fitted into the vertical grooves 21 of the lower cover 17, and the upper cover 22 is pushed up while sliding upward until the upper end abuts against the ceiling surface 1. Then, the locking protrusions 24, 24', 24'' of the pressing pieces 23, 23', 23'' are pushed apart by the lower cover 17 and escape, and the locking protrusions 24, 24', 2
When the upper part of 4″ gets over the lower cover 17,
Locking protrusions 24, 2 of pressing pieces 23, 23', 23''
4', 24'' return and engage with the upper end of the lower case 17 to prevent it from deviating downwards thereafter. They are engaged by appropriate mating steps on the pieces 24, 24', 24''. As mentioned above, the lower cover 22 includes the internal rosette 2, ceiling 3, and mounting bracket 7.
When the support fittings 12 are covered, the installation of the lighting fixture 6 is completed.

The length of the support arms 13, 13' of the support fitting 12 is determined by the distance between the upper end of the lower cover 17 and the ceiling surface 1, and the length between the upper end of the upper cover 22 and the locking protrusions 24, 24', 2.
Set it so that it matches the distance from the engagement step part of 4".

When installing the upper cover 22, the upper cover 22
If the upper cover 22 is pushed up toward the ceiling surface 1 from below, it will be automatically engaged and fixed, making the work easy.
The lower cover 17 is engaged and fixed to the lower cover 17.
The dimensional error between the locking protrusions 24 and 2 is
4' and 24'', no gap is created between the upper cover 22 and the ceiling surface 1, and the attachment portion of the lighting fixture 6 to the ceiling surface 1 can be completely covered.

As explained above, according to this invention, the upper cover can be easily engaged and fixed to the lower cover in a one-touch manner, and the upper edge of the upper cover is fixed with the top edge in contact with the ceiling surface. The mounting portion can be completely covered without creating any gaps. Further, both the upper cover and the lower cover have a simple structure, are easy to manufacture, are suitable for mass production, and can be provided at low cost.
