Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a mounting device for an embedded lighting fixture that is mounted on a ceiling surface using a leaf spring.

[Background Art] FIG. 4 shows a perspective view of a conventional lighting device main body 3, and a pair of leaf springs 4' are attached to the outer peripheral surface of this lighting device main body 3. This leaf spring 4' is attached so as to spread upward, and by pushing the leaf spring 4' towards the lighting fixture main body 3, the main body 3 is aligned with the embedded hole 2 opened in the ceiling 1, which is smaller than the outer circumference of the main body 3.
When pushed in, the plate spring 4' inserted through the embedded hole 2 returns outward, completing the installation. FIG. 5 shows this state, in which the flange 5 at the bottom of the main body 3 abuts the lower outer circumference of the embedded hole 2 in the ceiling 1, and the returning force of the plate spring 4' causes the plate spring 4' to be embedded. The main body 3 is attached to the ceiling 1 by making elastic contact with the inner edge of the insertion hole 2. Incidentally, the lamp 6 attached to the socket 7 is arranged inside the main body 3. Here, in FIG. 5, if the thickness of the ceiling 1 is thin and the size is A, the leaf spring 4' will expand greatly as shown by the solid line in the figure, and the main body 3
The fixation is ensured. Also, when the plate thickness of the ceiling 1 becomes thicker, such as dimension B, the plate spring 4' comes to the position indicated by the broken line in the figure, and the plate spring 4' becomes larger than in the previous case.
The elastic contact force of becomes weaker. However, there is no problem if the thickness of the ceiling 1 is as shown in Figure 5, but as shown in Figure 6, if the thickness of the ceiling 1 becomes even thicker, the leaf spring 4' will stand vertically. It is in a raised state, the upward pulling force is poor, and the spring force only works to press against the inner surface of the embedded hole 2.
If the device is heavy, there is a possibility that it may fall off. In addition, the ceiling board thickness is generally 3 mm to 45 mm.
The conventional leaf spring structure is only suitable for 3mm to 15mm.

[Purpose of the invention] The present invention was provided in view of the above-mentioned points, and the purpose is to provide a mounting device for a recessed lighting fixture that can maintain its holding force on both thin and thick plate ceilings. That is.

[Disclosure of the invention] Hereinafter, embodiments of the invention will be described with reference to the drawings.
The present invention is characterized by the structure of the leaf spring that is the spring body, and the lighting fixture body 3 itself is the same as the conventional example, so a description of this part will be omitted and the leaf spring will be explained. As shown in FIGS. 1 and 2, a pair of leaf springs 4 are attached to the outer surface of the lighting device main body 3, and the lower part of the leaf spring 4 is rotatably connected to the main body 3 by a shaft 8. It is attached. This leaf spring 4
is inclined upwardly of the main body 3 and has a biasing force outward from the main body 3. That is, the leaf spring 4 is pivoted at its lower end above the flange portion 5 to the circumferential surface of the main body 3 by a shaft 8 so as to be flexible in a plane parallel to the lower surface of the main body 3, Main body 3
It tilts away from the sky. Therefore, the leaf spring 4 can be bent so as to wrap around the peripheral surface of the main body 3. When the leaf spring 4 is wound around the circumferential surface of the main body 3, it has a length that extends from the bottom to the top of the main body 3. Further, a lever 9 is formed below the shaft 8 of the leaf spring 4 and projects laterally, and the upper end of the leaf spring 4 is approximately T-shaped to be hooked into a hook hole 11 formed in the main body 3. claw 1
0 is integrally formed. The leaf spring 4 has an urging force that opens outward with the shaft 8 as a fulcrum as shown in FIGS. 1 and 3b.

In order to attach the main body 3 to the embedded hole 2 in the ceiling 1, first, the claw 10 at the tip of the leaf spring 4 is bent and attached to the hook hole 11 of the main body 3. Then, as shown in FIG. 3a, the main body 3 is inserted into the embedding hole 2. Then, the lever 9 of the leaf spring 4 hits the lower surface of the ceiling 1, and the claw 10 of the leaf spring 4 hits the shaft 8 as the center.
is removed from the hook hole 11 of the main body 3, and the leaf spring 4 is removed from the third
As shown in Figure b, it opens linearly due to the return force. As shown in FIG. 3c, the lower edge of the leaf spring 4 comes into contact with the upper edge of the opening periphery of the embedded hole 2 in the ceiling 1, so that the main body 3 can be firmly fixed to the ceiling 1 regardless of its plate thickness. become. That is, although the leaf spring 4 is flexible in a plane parallel to the lower surface of the main body 3, it hardly bends in the vertical direction. Since the spring 4 does not bend, the main body 3 can be firmly fixed to the ceiling 1. Moreover, since the leaf spring 4 is inclined so that the upper part is further away from the main body 3, it can be installed regardless of the thickness of the ceiling 1, and the installation strength is almost the same regardless of the thickness of the ceiling 1. It becomes constant. Furthermore, the installation work of the lighting fixture body 3 is extremely simple, as it is simply pushed into the embedded hole 2 in the ceiling 1.

[Effects of the invention] As described above, the present invention has a flat spring that is flexible in a plane parallel to the lower surface of the lighting equipment main body and tilts away from the lighting equipment main body as the upper part approaches.
Since the lower end is fixed above the flange on the peripheral surface of the lighting fixture body, the leaf spring is flexible in a plane parallel to the bottom surface of the main body, but it hardly bends in the vertical direction. This has the advantage that the leaf spring does not bend even if a downward external force acts on the main body, and the main body can be firmly fixed to the ceiling. Furthermore, since the leaf spring is slanted away from the main body toward the top, it can be installed regardless of the thickness of the ceiling, and the installation strength is almost constant regardless of the thickness of the ceiling. be effective. Furthermore, since it is a plate spring, it can be automatically expanded after being wrapped around the main body and inserted into the embedding hole, making installation work extremely easy.
