[Detailed description of the invention] [Technical field] The present invention allows for easy attachment and removal of the reflector when attaching it to the mounting plate of a lighting fixture, and also prevents rotation when the reflector is attached. The present invention relates to a mounting structure for a reflecting mirror of a lighting equipment.

[Background Art] Generally, when attaching a reflector of a lighting device to a mounting plate, the reflector is attached by screwing, but with this method, the reflector must be turned by hand many times. Moreover, when the reflector is installed in a narrow space inside the shade, it is especially troublesome to attach and detach it.

[Purpose of the invention] The present invention has been made in view of the above points, and provides a lighting device that can be installed or removed with only a slight rotation, and that does not come off due to rotation due to external forces such as vibrations. The object of the present invention is to provide a structure for mounting a reflector on an instrument.

[Disclosure of the invention] That is, the reflecting mirror mounting structure for a lighting device of the present invention includes a mounting plate 4 by extending a plurality of engaging pieces 2 and inclined pieces 3 inside a frame body 1 formed in a frame shape. A cylindrical mounting portion 6 is provided at the base of the reflecting mirror 5.
An engagement recess 10 that is long in the circumferential direction is provided on the outer periphery of the mounting part 6, and a recess 9 that is long in the axial direction and that opens at the axial end face of the mounting part 6 is provided on the outer periphery of the mounting part 6. The mounting portion 6 of the reflecting mirror 5 is inserted into the frame 1 of the mounting plate 4, and the engagement piece 2 of the mounting plate 4 is passed through the recess 9 to the engagement recess 10 of the mounting plate 4.
By engaging the engaging piece 2 of the mounting plate 12 into the engaging recess 10 of the reflecting mirror 5, the reflecting mirror 5 is The above object is achieved by preventing the reflective mirror 5 from coming off and also by fitting the inclined piece 3 into the recess 9 of the reflecting mirror 5 to prevent the reflecting mirror 5 from rotating and coming off due to impact or the like.

The present invention will be described in detail below based on illustrated embodiments. As shown in FIG. 1, the reflecting mirror 5 is formed of a square frame-shaped metal plate or the like, and is formed by integrally extending an inclined piece 3 and an engaging piece 2 inside a square frame-shaped frame 1. ing. The inclined pieces 3 protrude from the center of the four sides of the frame 1, and are tapered so that their tips are inclined inward. The engaging piece 2 protrudes inward from the four corners of the frame 1, and has an engaging portion 11 bent slightly in the same direction as the inclined piece 2 at its tip.
is provided. These inclined pieces 3 and engaging pieces 2
Each has elasticity. on the other hand,
As shown in FIGS. 1 to 3, the reflecting mirror 5 of the lighting device has a generally bowl-shaped overall structure, and has a mounting portion 6 formed at its base. A stepped surface portion 7 is protruded from the outer periphery of the mounting portion 6 formed in a cylindrical shape, and a circumferentially long horizontal protrusion is formed on the outer periphery of the mounting portion 6 on the end side of the mounting portion 6 than the stepped surface portion 7. 12 and an axially long vertical protrusion 13 formed in an inverted L shape, four engagement protrusions 8 are provided with gaps between them, and a recess 9 is provided between the engagement protrusions 8 and 8. It is being Further, an engagement recess 10 is provided between the horizontal protrusion 12 of the engagement protrusion 8 and the stepped surface portion 7, and this engagement recess 10 communicates with the recess 9. The cross-sectional shape of the horizontal protrusion 12 of the engagement protrusion 8 is formed into a mountain shape, and the end surface of the horizontal protrusion 12 is formed with an inclined surface 14, and the side surface of the horizontal protrusion 12 is also formed with an inclined surface 15, respectively. has been done. Further, the cross section of the horizontal protrusion 13 is also formed in a substantially mountain shape.

Therefore, the position of the recess 9 formed in the mounting portion 6 of the reflecting mirror 5 having the above structure is formed to correspond to the position of the inclined piece 3 and the engagement piece 2 formed on the mounting plate 12. , when attaching the reflecting mirror 5 to the mounting plate 12 of the lighting equipment, insert the mounting part 6 of the reflecting mirror 5 into the frame 1 of the mounting plate 4 as shown in FIGS. 4 to 6. The engaging piece 2 is inserted into the recess 9 of 5. That is, the engaging piece 2 is inserted into the recess 9 shown by B in FIG. 5a. Next, when the reflecting mirror 5 is rotated to the right, the engagement piece 2 enters the engagement recess 10 formed between the engagement protrusion 8 and the stepped surface 7 from the position of the recess 9. (position shown by A in FIG. 5a), the engaging portion 11 of the engaging piece 2 is engaged between the horizontal protrusion 12 of the engaging protrusion 8 and the step surface portion 7 as shown in FIG. 5b. It will be done. Here, the inclined piece 3 has an engaging protrusion 8 when the reflecting mirror 5 is attached.
It is in elastic contact with the outer surface of the horizontal protrusion 12, and then by rotating the reflector 5, it moves from state B to state A in FIG. 6, and when the reflector 5 is attached, it is in the recess 9. It is fitted with At this time, the inclined piece 3 is elastically biased inward and comes into elastic contact with the mounting part 6 in the recess 9, and both the engaging protrusions 8, 8
Since the reflecting mirror 5 is located in between, rotation of the reflecting mirror 5 is restricted. Therefore, when attaching the reflector 5, the engagement piece 2 engages in the engagement recess 10 and cannot be removed, and the rotation of the reflector 5 is stopped by the inclined piece 3. , it will not come off due to external force such as vibration of the reflecting mirror 5. Furthermore, the mounting plate 12 also serves as a heat shield for the reflecting mirror 5.

Now, when the reflecting mirror 5 is to be removed from the mounting plate 12 of the lighting fixture, the reflecting mirror 5 is rotated approximately 45 degrees in the opposite direction to that described above. The engaging piece 2 moves in the circumferential direction from within the engaging recess 10 and is located within the recess 9, and the inclined piece 3 elastically moves from within the recess 9 onto the horizontal protrusion 12 of the engaging protrusion 8. I ended up riding it,
As a result, as soon as the engagement of the reflecting mirror 5 is released, the reflecting mirror 5 is pushed forward by the elastic force of the inclined piece 3, and the reflecting mirror 5 is ejected. Therefore, even when the reflecting mirror 5 is installed or removed in a narrow space surrounded by the shade 16 as shown in FIG. 7, the work is easy.

In addition, in the above embodiment, when attaching the reflecting mirror 5 to the mounting plate 12, the engaging piece 2 of the reflecting mirror 5 is attached to the mounting plate 1.
2 into the recess 9, and then the reflecting mirror 5 is rotated. However, the elasticity of the engaging piece 2 is used to apply the engaging protrusion 8 directly to the position of the engaging piece 2, and By pressing the reflector 5 toward the mounting plate 12, the engagement piece 2 is elastically deformed as shown from the imaginary line to the solid line in FIG. They may be fitted together.

[Effects of the invention] As described above, the present invention forms an engaging piece and an inclined piece on the frame, and provides communication between the engaging recess and the recess on the outer periphery of the mounting portion of the reflector. The mounting part of the mounting plate is inserted into the frame of the mounting plate, and the engaging piece of the mounting plate passes through the recess and is engaged with the engaging recess of the mounting plate, and the slanted piece is fitted into the recess. The reflector can be attached to the mounting plate by inserting the engagement piece of the mirror into the recess and rotating it so that it engages in the engagement recess, making it easy to attach the reflector without having to turn it many times. It also requires little rotational torque and is easy to attach and detach, even in narrow spaces. Further, at this time, the inclined piece fits into the recess to stop the rotation of the reflecting mirror, so that the reflecting mirror will not come off from the mounting plate even if an external force such as vibration is applied. Moreover, the reflector is attached with the inclined piece in elastic contact with the reflector, and when the reflector is removed from the mounting plate, the reflector will pop out from the mounting plate, making it easy to remove the reflector. It is something that can be done.
