Description

[Detailed Description of the Invention] [Technical Field] This invention relates to an open-bottom lighting device, and more specifically to a structure for attaching a light-transmitting panel frame that closes the open bottom portion of the reflector to the reflector.

[Background technology]

FIG. 1 shows a first conventional example, in which a slit hole 4 with which the magic spring 2 engages is bored in the reflection plate 3 when attaching the transparent panel holding frame 1 to the reflection plate 3 via the magic spring 2. are doing. That is, changing from a type with an open bottom surface to a type with a light-transmitting panel required slit hole processing (post-processing), which was troublesome in terms of time and tools.

FIGS. 2 and 3 show a second conventional example, in which a frame fixture 6 is fixed to a reflecting plate 5 with screws 7, and a holding frame 10 of a transparent panel 9 is attached to the frame fixture 6 via screws 8.
This is the one with the attached. In this case, since the screws 8 are fastened at four locations, it is very troublesome to attach and remove the holding frame 10, and the heads of the screws 8 are exposed, resulting in an unsightly appearance.

[Purpose of invention]

The purpose of this invention is to make it possible to easily attach and detach the transparent panel holding frame in the same way as magic springs, without having to drill holes in the reflector, and to improve the external appearance. be.

[Disclosure of invention]

In the lighting fixture of this invention, hanging fittings with holes are fixed to both ends of the translucent panel holding frame, and correspondingly, the reflecting plate is inserted and locked into the hole of one of the hanging fittings. A first fixture having a claw for swingably suspending the panel holding frame, and a second fixture having a claw that elastically engages with the hole of the other hanging fixture are attached. The first fixture has an outer upper first mounting surface and an inner lower second mounting surface as the mounting surfaces next to the corresponding hanging tool.

An embodiment of this invention will be explained based on FIGS. 4 to 12. In FIG. 4, which schematically shows the whole, 11 is a reflecting plate, 12 is a translucent panel holding frame, 13 is a hanger fixed to both ends of the holding frame 12, and 14 is a screw 15 attached to the reflecting plate 11. The first fixture 16 is attached to the reflecting plate 11 with screws 15.

The two hanging devices 13, 13 have the same shape and are provided symmetrically. Each of the hanging tools 13 has two left and right holes (square holes) 17 formed therein as shown in FIG. 5, and the upper part 13a is bent inward.

As shown in FIG. 6, the first fixture 14 has two claws 18, 18 that are inserted and locked into the holes 17, 17 of the hanging tool 13, and each claw 18 serves as a mounting surface for the hole 17. Upper first mounting surface 19 on the outer side (base side)
and an inner (free end side) lower second mounting surface 20. 21 is a screw hole.

The second fixture 16 has two claws 22, 22 that elastically engage the holes 17, 17 of the hanging fixture 13, as shown in FIG. 23 is a screw hole.

Note that the four screws 15 also serve as screws (thumb screws) for attaching the reflector 11 itself to the instrument body. Therefore, it is also possible to attach it to an existing lighting fixture with an open bottom surface.

Next, to explain the operation procedure, first, as shown in FIG. Place it on the mounting surfaces 19, 19. From this state, as shown in FIG. 9, the panel holding frame 12 is swung in the direction of arrow A and the right hanging tool
It is coupled to the fixture 16. At that time, the inwardly bent upper part 13a of the hanging tool 13 is bent over the claw 2 of the second fixture 16.
2, 22 are pushed outward once, and when the claws 22, 22 and holes 17, 17 are aligned, the claws 22, 22 are aligned with hole 1.
7 and 17.

The setting operation of the panel holding frame 12 can be performed in a one-touch manner and is extremely simple. Also, the claws 22,2
Since the elastic pressing force of 2 is applied, the set state is stable. The distances d ₁ and d ₂ shown in FIG. 4 are also kept constant. In particular, since there are two claws 18, 18 and two claws 22, 22 on the left and right sides, the frame 12 is prevented from tilting as shown by the imaginary lines in FIG.

When removing the panel holding frame 12 when replacing a lamp, etc., first pull down the frame 12 in the direction opposite to the arrow A in FIG. First fixture 14
from the first mounting surfaces 19, 19 of the claws 18, 18 to the second
By moving it to the mounting surfaces 20, 20, the distance between the left end of the frame 12 and the inner surface of the reflecting plate 11 is widened, and in this state, the frame 12 is greatly swung in the direction of arrow B as shown in FIG. This swing angle is determined by the hanging tool 13 and the claw 18.
There is a certain limit due to the contact with the frame 18, and the frame 12 remains suspended at that angle. Since the opening between the frame 12 and the reflecting plate 11 is large, lamp replacement can be easily performed.

In addition, the height dimension H of the reflection plate 11 shown in FIG. 4 is
It only needs to be around 70mm, making it much more compact than the magic spring type, which generally has a length of 140mm.

[Effect of idea]

According to the lighting equipment of this invention, the light-transmitting panel holding frame can be easily attached and removed in one-touch manner similar to magic springs, while eliminating the need to drill holes in the reflector plate. Maintenance and inspection such as lamp replacement can be performed without changing the lamp, and the appearance can be improved. Also, the first
Since the fixture has a first mounting surface on the upper outer side and a second mounting surface on the lower inner side as mounting surfaces for the hole of the corresponding hanging tool, when the holding frame of the transparent panel is removed, the second mounting surface By placing the hanger on the mounting surface, it is possible to widen the distance between the holding frame and the inner surface of the reflecting plate, and to widen the rotation angle of the holding frame. Therefore, there is an effect that lamp replacement is easy.
