Description

[Detailed description of the invention] The present invention relates to the improvement of a device for installing a louver to a lighting fixture. The louver holder has a plurality of plates 2 that protrude inwardly and has a spring property, and this louver holder has a through hole 3 formed in the plate 2, and a looper 4 disposed inside the lighting fixture body 1. A plurality of locking rods 5, 5 are installed horizontally so that the locking rod 5 protrudes from the outer surface of the looper 4.
The attachment of the louver to the lighting fixture, which is made by removably fitting the tip of the locking rod 5 to the JL3, is related to the device.

As shown in FIG. 2, a U-shaped louver holder is attached to a plate 2' on the inner circumferential surface of a box-shaped luminaire main body 1' in which a light source 6 is housed. This louver holder was used to place the locking rod 5 of the looper 4 on the plate 2', so there was no problem that the looper 4 could easily come off from the lighting fixture body 1' even if there was vibration or a small external force. there were.

As another conventional example, as shown in FIGS. 6 and 7, a U-shaped louver receiver with spring properties is used on both sides of the plate 2''.
A'' is curved in an arc to face each other, and the louver holder is connected to plate 2.
It has been proposed that the locking groove 5 of the looper 4 is accommodated in the bottom of the plate 2'', but even if the louver is installed in such a lighting device, if an external force is applied from below, the louver holder will be attached to the bottom of the plate 2''. The side plate 2a” easily expands outward and the looper 4
However, there still remains the problem that the lamp comes off from the lighting fixture main body 1''.

The present invention was developed in view of the above points, and its purpose is to prevent vibrations and some external force from being applied to the louver, even though the louver is easy to attach to the lighting equipment body. An object of the present invention is to provide a device for attaching a louver to a lighting fixture without causing the louver to come off the lighting fixture.

Hereinafter, the present invention will be explained in detail with reference to examples.

2 is a louver plate formed by bending a spring plate material at an acute angle, and the mounting part 7 is made up of a part 8, and the receiving part 8 has a through hole 3 in the center. For mounting, a tightening rivet insertion hole 7a is formed in the center of the portion 7, and a rotation stopper projection 7b is provided at the lower edge.

The lighting fixture main body 1 is box-shaped with an opening at the bottom, and the inner peripheral surface of the lower edge of the opening is provided with tightening stud insertion holes 9 at appropriate intervals in the circumferential direction. A stop notch 10 is formed.

Then, after inserting the anti-rotation protrusion 7b into the anti-rotation notch 10, the louver receiver plate 2 is fixed to the lighting fixture body 1 with the rivets 11. The receiving portion 8 of No. 2 protrudes toward the inside of the lighting fixture body 1 as it goes downward.

As shown in FIG. 9, if the tip of the locking rod 5 of the louver 4 is moved downward while sliding it onto the outer surface of the receiving part 8 of the louver plate 2, the receiving part 8 will be drawn along the broken line. If the locking rod 5 is bent as shown in and further moved downward, the rounded tip of the locking rod 5 will fall into the through hole 3 of the plate 2, and at the same time, the louver support will move back from the original position of the plate 2. The tip of the locking rod 5 of the louver 4 is then fitted into the through hole 3 of the plate 2.

FIG. 10 shows another embodiment of the present invention, in which the louver holder is from part 8 of piece 2 to part 12 of the U-shaped preliminary holder.
The louver holder of the locking rod 5 of the louver 4 can be used to prevent the louver 4 from falling if the fitting operation to the plate 2 is mistaken, and even if the springiness of the plate 2 deteriorates. I try not to.

11 and 12 show an example in which the locking rod 5 is biased outward by a spring and the tip of the locking rod 5 is directly fitted into the lighting fixture body 1, and is fixed to the louver 4. Spring plate 13
is attached to the base of the locking rod 5, and the tip of the square locking rod 5 is moved inward against the spring force of the spring plate 13. The tip of the rod 5 can be fitted by the spring force of the spring plate 13.

15 is a stopper, and 16 is a ceiling plate.

As described above, the present invention has a louver holder with a plate protruding from the lower edge of the lower edge of the main body of the box-shaped lighting fixture, which has an opening at the bottom. A through hole is formed approximately in the center of the plate in the protruding direction, and the end of the locking rod protruding from the louver is removably fitted into this hole, so the tip of the locking rod of the louver is inserted into the louver receiver. If the outer surface of the board is slid and moved, the locking rod can be easily fitted into the hole in the board, making it easy to install the louver to the lighting fixture body. Once the louver retainer is fitted into the through hole of the plate, the louver locking rod will not fall off due to external force applied to the louver, and when attempting to remove the louver, the louver retainer will hold the plate. This has the effect that it can be easily removed by simply bending it.

Furthermore, by attaching a plurality of locking rods to the louver in a horizontal direction so that the locking rods protrude from the outer surface of the louver, and by attaching the tips of the locking rods to the main body of the lighting fixture, the locking rods can be fixed horizontally. The louver and the lighting fixture body can be connected through the louver, and there is no need to drill holes in the louver for attachment, making the structure of the device extremely simple.
