Description

[Detailed description of the invention] The present invention relates to a mounting structure for fixing an automobile floor carpet, deck carpet, etc. to a body panel, and in particular, a mounting structure that prevents the head of the fixing clip from appearing on the surface of the carpet during installation. Regarding structure.

When installing a deck carpet for an automobile, as shown in FIG. 1, a deck carpet 1 is placed on a body panel 2 and fixed to the body panel 2 by a plurality of mounting portions 3.

As shown in the cross section of FIG. 2, the structure of one example of the conventional carpet attachment part 3 is that the carpet 1 has a felt 1b under the carpet body 1a and is fixed on the body panel 2. In the carpet 1, a through hole 1c for passing the mounting clip 4 is formed, and at the same position, a mounting hole 2a is also formed in the panel 2, and the clip 4 is inserted into the through hole 1c and the mounting hole 2a. The head 4a and the locking part 4b are used to fix the head 4a and the locking part 4b.

Although this mounting structure is simple and low cost, it has the following drawbacks.

That is, the head portion 4a of the clip 4 protrudes onto the surface of the carpet 1, resulting in a poor appearance, and the surface of the carpet body 1a around the through hole 1c is pressed into a concave shape by the head portion 4a of the clip, which reduces the flatness of the carpet 1. is damaged. As a result, the carpet 1 was wrinkled and wavy. Also, if the carpet 1 is pulled by some force,
The through hole expands and becomes larger, and the head 4a of the clip
sometimes fell off the carpet 1.

Another example of a conventional carpet mounting structure is as shown in FIG. That is, the head 14a of the clip 14 is fused to the back inner layer of the back surface of the carpet body 11a, and the through hole 11 of the felt 11b is fused.
c. The clip 14 was passed through the mounting hole 12a of the panel 12 and fixed by the locking part 14b. However, this mounting structure
Although it has the advantage of not being exposed to the surface of the carpet 11, it has the following drawbacks. Since the carpet 11 and the clip 14 are fixed and cannot be moved relative to each other, they cannot absorb the expansion and contraction of the carpet 11, dimensional tolerances, etc., and wrinkles, waves, etc. are likely to occur. Because the head 14a is fused over a small area, its attachment strength is insufficient, and the carpet often peels off at the fused portion or destroys the backing layer of the carpet body 11a.

The purpose of this invention is to prevent mounting members such as clips from being exposed on the carpet surface at the carpet mounting part, prevent wrinkles and waving of the carpet attached to the body panel, improve flatness, and achieve greater mounting strength. An object of the present invention is to provide an automobile carpet mounting structure that can be installed in a car. That is, the present invention provides a structure for attaching an automobile carpet to a body panel at a plurality of attachment points, which includes: on the back side of each attachment section of the carpet, an annular presser fixed to the carpet at the peripheral edge and having a center hole; A mounting structure for a carpet for an automobile, comprising a clip whose head is fixed between the back surface of the carpet and the presser, and the clip is fixed to a mounting hole drilled in a body panel. It is.

Next, the present invention will be explained based on embodiments with reference to the drawings. FIG. 4 is a sectional view showing the carpet mounting structure of the present invention, in which the carpet main body 21a is mounted to the body panel 22 via the felt 21b. At the mounting part 23, the carpet body 2
An annular presser 25 having a center hole 25d is fixed to the back surface of 1a. As shown in FIG.
5b are laminated. The fiber reinforcing material is preferably a plain weave fabric such as jute or polypropylene, and the thermoplastic synthetic resin is polyethylene, polypropylene, EVA, etc., but the same type as the carpet backing layer is preferred from the viewpoint of fusion bonding properties. The presser 25 is fused to the carpet body 21a at a fused portion 25c at its outer periphery, and the other portions are separated from each other. A clip 24 having a head 24a having a larger diameter than the center hole 25d is secured to the carpet body 21a by a presser 25 at the head 24a. FIG. 5 is a perspective view showing the state in which the clip 24 is engaged with the presser 25. The outer diameter of the presser 25 is determined depending on the size of the head 24a of the clip 24, but for example, when the diameter of the head 24a is 18 mm, it is preferably 30 to 50 mm. In this case, the inner diameter of the center hole 25d is 8
It is preferable to set it to 13 mm. Outer diameter of head 24a
D ₁ is smaller than the inner diameter D ₂ of the fused portion 25c, and the inner diameter d ₂ of the center hole 25d is larger than the outer diameter d ₁ of the clip 24. To attach the clip 24 to the presser 25, the clip 24 is first passed through the center hole 25d of the presser 25, and then fused to the backing layer on the back surface of the carpet body 21a at the fused portion 25c. Fusion may be performed by pressing with a heated ring, or may be performed using an ultrasonic welder. As a result, the head 24a of the clip 24 is trapped in the bag-shaped portion formed by the presser 25 and the carpet body 21a, and does not come off. Further, by allowing the inner diameter 25d of the presser 25 to have a margin with respect to the clip 24, it becomes possible for the clip 24 to be slightly displaced with respect to the carpet 21.

To attach the carpet 21 to the body panel, the clip 24 can be pushed into a mounting hole 22a formed in the mounting portion, and the clip 24 will not come off due to the locking portion 24b.

According to the present invention, since the clip 24 is attached to the back side of the carpet by the presser 25, the clip does not appear on the carpet surface at all, so the appearance is good, and since the clip and the carpet are integrated, the carpet body It is easy to assemble to the panel, and the clip and carpet can be slightly misaligned, and the presser is fixed with a circumference larger than the head of the clip, so stress from the carpet can be easily dispersed, so it can be easily attached to the carpet. Wrinkling, waving, etc. are prevented and flatness is excellent, and the outer periphery of the presser is fixed to the carpet and reinforced with fiber reinforcing material.
A high attachment strength of the clip is achieved.
