Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for a spring nut for a vehicle lamp, and its purpose is to prevent the nut from falling off during installation and also to position the nut.

Looking at the conventional installation of this type of spring nut, as shown in Fig. 1, which is a perspective view of the main part, one terminal b is bent open and the upper and lower surfaces are bent to make it easier to install. A spring nut N (hereinafter simply referred to as a nut), which has screw holes h and h' drilled therein and is bent so as to have a roughly U-shaped cross section, is attached to the spring nut N (hereinafter simply referred to as the nut), which has a screw hole h'' drilled at one end. It is fitted onto the main resin panel P, and then fixed by inserting screws into each of the screw holes h, h', h''.

This type of spring nut is used for attaching moldings to vehicle lights. That is, as shown in FIGS. 5 and 6, a nut N is fitted into a rising portion E integrally provided on the lamp body B, and a screw A is inserted.
The molding M is attached to the rising part E by the following method, but during the assembly process, before inserting the screws, other objects occasionally collide with other objects while the nuts N are fitted, and each screw hole becomes misaligned. Occasionally, screws may fall off from the panel P, making it impossible to insert screws, resulting in inconveniences such as repeating the above-mentioned work, which reduces work efficiency.

This proposal is intended to solve the above-mentioned difficulties as much as possible, and the specific configuration of one embodiment will be described in detail below with reference to FIG. 2 and subsequent figures.

Figure 2A is a plan view of the spring nut according to the present invention, and Figure 2B is a cross-sectional view taken along line a-a. so that e′ stands out, and
It is slightly curved outward, and a bowl-shaped bulge w is formed near the other end to maintain elasticity when a screw (not shown) is screwed in, like a spring washer. The body portion t is folded in half to form a substantially U-shape. In addition, h,
h' indicates the screw insertion hole.

On the other hand, as shown in FIG. 3 as a perspective view of the actual product before installation, P is a panel that forms a part of a vehicle lamp made of resin or the like, and when the nut N is installed, the screw insertion hole An insertion hole h'' is drilled at a position corresponding to h and h', and holding pieces K and K' are attached to the panel P on both sides of the hole h'' so as to be higher toward the depth than the front side. They are arranged integrally or separately, and the distance d between both holding pieces K and K' is
is such that the width w' of the trunk t of the nut N is suitable for clamping and holding, and the length l is also suitable for restraining the ears e and e' when the nut N is attached. Each is determined.

The present invention consists of the above-mentioned structure.Next, to describe the mode of implementation and the effect, as shown in FIG. 3, the ears e and e' of the nut N are opposed to the edge of the panel P, It is best to push the nut in the direction of the arrow in the same figure; however, the ears e,
e' slides on the holding pieces K and K', while the other end of the nut N is restrained by the back surface of the panel P, and gradually both sides of the nut N are restrained on the holding pieces K and K'.
While being restrained and guided by K', it is gradually expanded to increase the elastic clamping force, and finally, when the rear ends of the holding pieces K and K' are removed, the clamping force by each holding piece is released. It falls onto the panel surface and strongly clamps both sides of the panel, while also restraining the nut N from moving in the opposite direction. It is preferable to insert screws (not shown) into each insertion hole and screw them in place.

According to the merits of the case, as stated above, Natsuto N.
However, since the holding pieces K and K' correctly restrict the installation direction, and also restrict movement in the removal direction after installation, there is no risk of it falling off even if it hits another object during assembly work. Since there is no damage to the screw, and it is properly fixed in place before the screw is inserted, it has an excellent effect of fully achieving the intended purpose stated at the beginning of this section.

The nut mounting structure of this proposal is shown in Figures 5 and 6.
This is used when attaching the molding as shown in the figure, and the present invention is not limited to the configuration shown in the figure. For example, the holding pieces K and K' are
Of course, it may be provided on the back side of the panel P, and in this case, the ears e and e' of the nut N may be positioned downward, and the seat w is not necessarily required. Alternatively, a separate nut may be attached to the insertion hole h' without cutting a female thread.
