Description

[Detailed Description of the Invention] <<Field of the Invention>> This invention relates to an improvement of a clip for attaching a trim part to a vehicle body panel.

<Prior art and its problems> As is well known, various trim parts such as door trims, body sides, rear parcels, etc. are installed in the interior of an automobile, and the installation of such trim parts is shown in Fig. 4. Attach the attachment part 4 formed at one end of the clip 3 to the Daruma hole 2 provided in the trim part 1, and attach the elastic fitting piece 5 provided at the other end of the clip 3 to the vehicle body panel 6. The trim part 1 is attached to the vehicle body panel 6 by being elastically fitted into the hole 7.

The attachment part 4 consists of a head flange 4a formed at the tip of the clip, and a center flange 4b formed at a constant interval in the axial direction from the head flange 4a. After being inserted into the large diameter hole 2a, the clip 3 is held in the trim component 1 by passing through the communication hole 2b and positioning it in the small diameter hole 2c.

In FIG. 5, the trim part 1 is replaced by the vehicle body panel 6.
Shown is the installed state.

By the way, trim parts have recently become more sophisticated, and with this, breathable skin materials 8 such as carpet and woven fabric are often used for the skin material used for trim parts 1. if you did this,
Air flows in from the inside of the vehicle through the Darumi hole 2 made in the trim part 1, and as the air flows in, dust, dirt, etc. P from the vehicle interior adheres to the surface of the skin material 8, and especially in door trims, clips There are more than 10 attachment points, and dust and dirt from inside the vehicle adheres to all of these clip attachment points, which significantly degrades the product design.
There was also the problem that the environment inside the car was not favorable.

As a countermeasure to this problem, it has been proposed to cover the pothole with adhesive tape or the like after attaching the clip, but this is not a practical solution as it requires a large number of man-hours as there are many places to attach the clip.

《Purpose of the invention》 This invention was made in view of the above-mentioned circumstances, and its purpose is to close the clip mounting hole of the trim part with a simple structure.
To provide a clip for attaching trim parts that prevents air from flowing in from inside the vehicle interior, keeps the surface of the trim components beautiful, and improves the interior environment of the vehicle.

<Structure and Effects of the Invention> In order to achieve the above object, the present invention comprises a molded core material formed into a desired shape and provided with a drilled hole for attaching a clip, a breathable skin material covering the surface of the core material. A clip for attaching a component is attached to the above-mentioned rounding hole in order to attach a trim component consisting of , a center flange, a clamping part that clamps the trim part between the flanges, and an elastic fitting piece that is fitted into the mounting hole of the vehicle body panel.
The center flange is tightly sealed along the dart hole of the trim part, thereby restricting the inflow of air from the inside of the passenger compartment to the vehicle body panel side through the breathable skin material and the dart hole.

In other words, in the parts attachment clip according to the present application, a part of the center flange extends in the radial direction to form a substantially elliptical shape, and by blocking the dart hole with the center flange, it is possible to attach the clip to the vehicle body from the inside of the vehicle. It can reliably prevent air from flowing into the panel side, and it can reliably prevent dust, dirt, etc. from adhering to the surface of trim parts due to this air inflow, so the product surface can be kept beautiful for a long time. At the same time, the environment inside the vehicle can also be improved.

Furthermore, compared to conventional methods that use adhesive tape to cover the clip mounting holes, the Darthole hole is simultaneously blocked by simply installing the clip in the correct position, so there is no need to increase the work process for clip mounting. This is a practical device that can achieve the above-mentioned effects.

<<Description of Embodiment>> Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is an overall perspective view illustrating how the clip is attached according to the present invention, Fig. 2 is a vertical sectional view showing how the clip is attached, and Fig. 3 is a perspective view of the clip showing another embodiment. .

In FIG. 1, reference numeral 10 indicates a trim component 10, and this trim component 10 consists of a molded core material 11 such as a hardboard or composite resin board molded into a desired shape, and a molded core material 11 that is adhered to the surface of the molded core material 11. It is composed of a breathable skin material 12 such as a carpet or cloth material.

Furthermore, a pothole 13 is drilled in the molded core 11 for attaching a clip to the trim part 10. As is clear from FIG. 1, this Daruma hole 13 consists of a large diameter hole 13a, a small diameter hole 13b, and a communication groove 13c that communicates the two.

On the other hand, the clip 14 attached to the Daruma hole 13 has a holding part 15 attached to the trim part 10 at one end, and elastically fits into the attachment hole 17 provided in the vehicle body panel 16 at the other end. The elastic fitting piece 18 is provided. More specifically, the holding portion 15 includes a thin circular head flange 19 that is flanged in the radial direction of the clip 14, and a thin circular head flange 19 that is flanged in the radial direction and that extends from the head flange 19 at a predetermined interval in the axial direction. The center flange 20 has a thin center flange 20 with a portion further extending in the radial direction, and is formed into a substantially elliptical shape. In addition, the above head flange 1
9 and the center flange 20, both flanges 19 and 20 are connected by a neck portion 21 having a length approximately equal to the plate thickness of the molded core material 11.

Next, when attaching the clip 14 to the trim part 10, the head flange 19 of the clip 14 is inserted into the pothole 1 provided in the molded core material 11.
After inserting the clip 1 into the large diameter hole 13a of No. 3,
4 is passed through the communication groove 13c and positioned in the small diameter hole 13b. At this time, the diameter of the neck 21 of the clip 14 is set to be slightly larger than the diameter of the communication groove 13c of the Daruma hole 13, so if the clip 14 is attached to the small diameter hole 13b of the Daruma hole 13, the clip 14 will be held at this position. Vehicle body panel 1 without falling off
6, clip 14 should be attached to small diameter hole 1.
It will be loosely fitted with the mounting clearance 3b included. Note that a tapered piece 22 that slopes outward is integrally formed on the inner surface of the center flange 20, and the clip 14 is inserted into the Daruma hole 1.
When the tapered piece 22 is installed in the appropriate position in the small diameter hole 13b of No. 3, the wall portion 22a of this tapered piece 22 fits into the large diameter hole 13a of the Daruma hole 13, and due to the resin elasticity of the center flange 20, the wall portion 22a of the tapered piece 22 fits around the large diameter hole 13a. By tightly sealing the center flange 20, the large diameter hole 1
3a is reliably closed and this closed state is reliably maintained (see FIG. 2).

As described above, in the case of the clip 14 according to the present invention, when the clip 14 is attached to the trim part 10, the center flange 20 of the clip 14 reliably closes the dart hole 13, so that It is possible to reliably prevent air from flowing in, and to reliably prevent the surface of the skin material 12 from being soiled due to air inflow.

In the above-mentioned embodiment, the center flange 20 of the clip 14 is in contact with the back surface of the molded core material 11 of the trim part 10 to close the dart hole 13, but as shown in FIG. It is obvious that the same effect can be obtained by fitting the center flange 20' of the clip 14' into the large diameter hole 13a of the Daruma hole 13, and in the present invention, the clip is attached to the trim part. There is no particular restriction on the shape of the center flange as long as the center flange of the clip closes the drill hole of the trim part in this state.
