Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a mounting bracket for being held in a slit hole of a downlight or the like.

This invention is a mounting bracket that can be used for things other than downlights, but downlights here refer to lights that are recessed into the ceiling by drilling holes in the ceiling. However, it was intended purely for the function of "lighting" and is currently being used in large quantities.

<Prior art> For example, a ceiling-embedded downlight consists of a downlight frame F for attaching a beam light bulb E, etc., as shown in Fig.
A hole H larger than the frame flange G is drilled at the lower part of the downlight frame for inserting the downlight frame F, and the frame flange G is left behind so that the downlight frame F can be inserted into the ceiling T. Note that P is a packing material. On the other hand, vertical groove-shaped frame slit holes S, S are bored in the downlight frame F, and these frame slit holes S, S are held between the downlight mounting fittings.

Fig. 3 shows a conventional example of a downlight mounting bracket (A), but the main body (B) of the mounting bracket requires a thumb screw (B) to be screwed together, so the screwing process is troublesome.
There was a drawback that the thumbscrews were damaged.

Figure 4 shows another conventional example of a downlight mounting bracket (2).The upper end of the main body of the mounting bracket (H) is folded back to form a spring shape, so the clip body is fitted with an arc-shaped outer fitting. It takes a lot of effort to insert the downlight into the section, and the downlight frame F has the disadvantage that it can only hold items of a certain thickness.

Figure 5 shows another conventional example of a downlight mounting bracket.The main body of the mounting bracket and clip are integrated, and can be held even if the thickness of the downlight frame F is slightly different. Although claws are provided on the periphery of the main body, they are not perfect and have the disadvantage of damaging the downlight frame F.

<Problems to be solved by the design diagram> In view of the above circumstances, the present invention is designed to clamp the slit in the slit hole without requiring any effort, without fear of loss, without being affected by the thickness of the slit hole, and with no risk of damage. The purpose of the present invention is to provide a one-touch mounting bracket for the purpose of

<Means for solving the problem> The mounting bracket of the present invention is composed of a main body and a clip body that are integrated as in the conventional example shown in Fig. 5, so that it does not require any effort and there is no risk of loss. did.

In addition, the tip of the shoulder of the clip body is biased and engaged with the frame slit hole, so that the clip is not affected by the thickness of the slit hole without using a claw, and there is no risk of damage. Therefore, the above problems were solved.

<Function> When the tip of the shoulder of the clip body engages with the frame slit hole, it means that the tip of the shoulder of the clip body is supported so as to pierce the surface of the frame slit in an inclined manner. This effect can be achieved by selecting the angle of inclination of the shoulder, the acute angle of the tip, and the distance from the main body. Specifically, the inclination angle is preferably about 18 to 22 degrees.

Also, biasing the clip body against the slit hole means using a spring force to engage the clip body, and in order to do so, at least the tip of the shoulder portion of the clip body must be made of HRC39 to 50, which has been heat-treated by quenching. It must be a hardened steel body with hardness,
This is because if the HRC is less than 39, the material is too soft, and if the HRC is more than 50, the material is too hard and may break.The HRC is preferably in the range of 42 to 49, and the optimum value is around HRC47. Since the clip body made of such a hardened steel body has spring characteristics, it has a repulsive spring force and can reliably act in a biased state.

<Example> The case of a downlight, which is an example of the mounting bracket of the present invention, will be described below with reference to the attached FIGS. 1A, B, and C and FIG. 2.

A downlight mounting fitting 1 consists of a clip body 2 and a main body 3. Clip body 2 is
Made of hardened steel body hardened to HRC47 hardness,
The lower half has a tongue-like shape, and the peripheral edge of the lower end 4 is rounded, but it may of course be straight.
The upper part of this tongue-like part has shoulders 5, 5 extending horizontally in the left-right direction, and the tips of these shoulders 5, 5 are located toward the back in the case of FIG. In the case of D, the shape is shaped like an acute angle a to the right, that is, it is not rounded. both shoulders 5,
5 has a neck 6 extending vertically (up and down in the case of FIG. 1B) above the center. At the upper end of this neck portion 6, support shaft portions 7, 7 extending horizontally in the left-right direction are provided. However, as shown in FIGS. 1B and 1D, the support shafts 7, 7 are plate-shaped and not cylindrical.

On the other hand, the main body 3 is provided with a support portion 8 whose lower half portion protrudes diagonally toward the outer surface O, and the lower end thereof is bifurcated to form support ends 9, 9. In the middle part of the support part 8, there is a lower tongue piece part 11 which is connected to the connection 10 at the lower part and projects to the inner surface I at the upper part. At the tip of the lower tongue piece 11, flanges 12, 12 project horizontally and are wider than the width s of the slit hole.
Similarly, in the upper middle part thereof, there is provided a tongue piece part 14 which is connected at the upper part to a connection 13 and which projects to the inner surface I at the lower part, for hooking at least the lower end 4 of the clip body 2. Further, at the upper end of the main body 3, an arcuate outer fitting part 15 is provided for rotationally gripping the support shaft parts 7, 7 of the clip body 2.

The mounting bracket 1 of the present invention has a frame slit hole S.
is held between the clip body 2 from the inner surface I. However, the neck portion 6 is shaped to straddle the frame slit hole S, and the support shaft portions 7, 7 protrude toward the outer surface O. Further, from the outer surface O, it is held between the main body 3. However, tsuba 1
2, 12 and the tongue portion 14 enter toward the inner surface I.

The mounting bracket 1 of the present invention is inserted across the inner surface I and the outer surface O in this way because the upper part of the frame slit hole S has a wide mouth S', so it is inserted from this part. reduce. This lowering is done until the supporting ends 9, 9 are placed on the ceiling T. In this state, if the clip body 2 is pressed,
First, the acute angle a at the tips of the shoulders 5, 5 of the clip body
However, as shown in FIG. 1D, in this embodiment, it is engaged with the surface of the frame slit hole S at an oblique angle of about 20°, so
Although the mounting bracket 1 can be moved downward, it cannot be moved upward, and in this state, the lower end 4 of the clip body
If the clip body 2 is hooked on the tongue piece 14,
Since it is made of hardened steel with a hardness of HRC47, it has a repulsive spring force and is held in a biased state.
Make sure to hold it securely.

<Effects of the invention> The mounting bracket of the present invention uses a two-stage method in which the shoulder of the clip body is first engaged, and then the clip is clamped under the biased state of a spring. It is convenient because it allows reliable clamping regardless of the thickness of the surroundings and can be done with one touch.

Furthermore, the present invention provides a new mounting bracket with a spring that is useful and practical and can be widely used for curtains, doors, etc. other than downlights without causing damage.
