[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for attaching a heel mat to a floor carpet laid on the floor of a vehicle such as an automobile.

[0002]

2. Description of the Related Art As shown in FIG. 6, a floor carpet (1) for an automobile floor mat is provided on the driver's seat side.
A heel mat (2) is attached to prevent wear of the heel. Floor carpet with such heel mat (2)
Conventionally, as shown in FIG. 7, a hot-melt adhesive (3) is applied to the heel mat (2) in a bead shape about 10 mm inward from the rear edge of the heel mat, as shown in FIG. There is provided a structure in which a mat (2) is bonded to a predetermined position of a floor carpet (1) by pressing the mat (2) between an upper mold (4A) and a lower mold (4B) of a press (4) (Japanese Utility Model Publication No. Sho 63-2697).
No. 6).

[0003]

[Problem to be solved by the invention] In the conventional structure described above, when the heel mat (2) is crimped to the floor carpet (1), the hot melt adhesive (3) is applied to the floor carpet (1).
Flow to the root of the pile layer (1A) of the pile, thereby firmly bonding the heel mat (2) to the floor carpet (1) and sealing between the heel mat (2) and the floor carpet (1). Garbage and the like do not enter.

However, recently, as the floor carpet (1) is upgraded, the density and length of the pile layer (1A) tend to increase. In the floor carpet (1) having such a high-density and long pile layer (1A), the hot-melt adhesive of the heel mat (2) is used as shown in FIG.
(3) is difficult to flow to the root of the pile layer (1A) to form a gap S, and the heel mat (2) is in a floating state with respect to the floor carpet (1) of the heel mat (2). The adhesive strength is reduced, and the space between the heel mat (2) and the floor carpet (1) is not sealed, and there is a possibility that dust or the like may enter.

[0005] Even in the case of a floor carpet (1) having a high-density and long pile layer (1A), the pile layer (1A) can be increased by increasing the amount of hot melt adhesive (3) applied to the heel mat (2).
The hot melt adhesive (3) can flow to the root of the heel mat (3). In this case, the hot melt adhesive (3) protrudes from the periphery of the heel mat (2) as shown in FIG. If the hot melt adhesive (3) is applied more than 10 mm from the periphery of the heel mat (2) to prevent this, there is a problem that the periphery of the heel mat (2) is turned up.

[0006]

Means for Solving the Problems The present invention provides a floor carpet (1) as a means for solving the above-mentioned conventional problems.
A plurality of through holes with (1B) provided at a predetermined location of the through-hole (1B)
The heel mat (2) is adhered to the heel mat (2) with an adhesive (3) at the portion (1), and an attachment structure for the heel mat (2) is provided, in which the adhesive (3) flows into the through hole (1B) .

[0007]

[Function] In the present invention, since a plurality of through holes (1B) are provided at predetermined positions of the floor carpet (1),
Heel mat (2) of the adhesive when the adhesive (3) is inflows City said through <br/> hole (1B), protrudes from the surrounding heel mat (2)
It is prevented that to, and improves the adhesion and sealing properties by the anchor effect.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to an embodiment shown in FIGS. 1 to 5. The floor carpet (1) has a pile layer (1A) and a plurality of holes (5A) as shown in FIG. Is placed on a receiving table (5) arranged on the upper surface, and is pierced by a piercing jig (4) having a plurality of piercings (4A). As shown in FIG. Multiple through holes on driver side shown
(1B) is provided.

On the other hand, as shown in FIG. 3, a heel mat (2)
Hot melt adhesive about 10mm inside from the back edge
(3) is applied in a bead shape with an applicator (6),
While the adhesive (3) is kept in a softened state, the heel mat (2) is placed at a predetermined position on the floor carpet (1), and is placed on a press (7) as shown in FIG. Mold (7A) and lower mold (7B)
To press the heel mat (2) against the floor carpet (1).

At this time, as shown in FIG.
Through hole (1) (1B) Heel mat (2) and positionally corresponding hot melt adhesive agent applied on the rear surface and (3), said hot-melt adhesive (3) the through-hole (1B) since the flow solidified by entering within, strong adhesion and good sealing properties by the anchor effect without increasing the amount of coating hot-melt adhesive (3) is obtained. The hot melt adhesive (3) does not protrude from the periphery of the heel mat (2) even when applied about 10 mm inward from the periphery of the heel mat (2).

[0011]

In the [effect of the proposed] Accordingly, the present invention, adhesives is a protruding to the carpet surface from the periphery of the heel mat
Contamination without, and even density of the pile layer is high and the long fine carpet can be adhered firmly and sealed with good heel mat.
