Description

[Detailed description of the device]

[0001]

[Industrial applications]

 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]

[Prior art]

 As shown in FIG. 6, a heel mat (2) is installed on the driver side of the floor carpet (1) for automobile floor covering to prevent the wear of the floor carpet (1). In order to attach such a heel mat (2) to the floor carpet (1), as shown in Fig. 7, a bead-like hot melt adhesive (3) is applied to the inside of the heel mat (2) by about 10 mm from the rear edge. A structure in which the heel mat (2) is applied to the floor carpet (1) at a predetermined position as shown in FIG. 8 by pressing it between the upper mold (4A) and the lower mold (4B) of the press (4). Is provided (Jitsuko Sho 63-26976).

[0003]

[Problems to be solved by the device]

 In the above conventional structure, when the heel mat (2) is pressure-bonded to the floor carpet (1), the hot melt adhesive (3) flows to the root of the pile layer (1A) of the floor carpet (1), As a result, the heel mat (2) is firmly adhered to the floor carpet (1) and the space between the heel mat (2) and the floor carpet (1) is sealed to prevent dust and the like from entering.

However, recently, the density and length of the pile layer (1 A) tend to increase as the floor carpet (1) becomes more sophisticated. In the floor carpet (1) having such a high density and long pile layer (1A), as shown in FIG. 9, the hot melt adhesive (3) of the heel mat (2) is the pile layer (1A). The heel mat (2) is in a floating state because it does not easily flow to the root of the heel mat (2) and the adhesion strength of the heel mat (2) to the floor carpet (1) is lowered, and the heel The mat (2) and floor carpet (1) may not be sealed and dust may enter.

Even in the case of a floor carpet (1) having a high density and a long pile layer (1A), if the application amount of the hot melt adhesive (3) of the heel mat (2) is increased, the root portion of the pile layer (1A) is increased. The hot melt adhesive (3) can be flowed up to, but in this case, as shown in FIG. 10, the hot melt adhesive (3) protrudes from the periphery of the heel mat (2) and spoils the appearance. In order to prevent this, if the hot melt adhesive (3) is applied to the inside of the heel mat (2) by 10 mm or more from the peripheral edge, the peripheral edge of the heel mat (2) may be turned up.

[0006]

[Means for Solving the Problems]

 As a means for solving the above conventional problems, the present invention has a heel mat (2) in a mounting recess (1B) formed by melting or cutting a pile layer (1A) at a predetermined location of a floor carpet (1). It provides a structure for attaching a heel mat in which the above is adhered by an adhesive (3).

[0007]

[Action]

 According to the present invention, the pile layer (1A) is melted or cut at a predetermined portion of the floor carpet (1) to form a mounting recess (1B), and a heel mat is formed in the mounting recess (1B) with an adhesive (3). Glue (2). Therefore, even when the pile layer (1A) is dense and long, the adhesive (3) can reach the bottom of the floor carpet (1) without increasing the coating amount.

[0008]

【Example】

 1 to 5, the floor carpet (1) has a pile layer (1A) and is made of a heat-meltable fiber such as polypropylene fiber or low-melting polyester fiber. I am trying.

As shown in FIG. 1, the floor carpet (1) is contacted with a heating jig (5) at a predetermined position, for example, the driver's seat side shown in FIG. 6, to melt the pile layer (1A), As shown in 2, form a groove-shaped mounting recess (1B). It is desirable that the temperature of the heating jig (5) be higher than the melting point of the fibers of the pile layer (1A) by about 10 ° C., and the width of the mounting recess (1B) is usually about 10 to 15 mm. And Further, it is desirable that the pressing surface (5A) of the heating jig (5) be embossed to form fine unevenness on the surface of the mounting recess (1B) to improve the adhesive strength by the anchor effect.

On the other hand, as shown in FIG. 3, a hot melt adhesive (3) is applied in a bead shape by an applicator (6) on the inner side of the back surface of the heel mat (2) by about 10 mm to soften the adhesive (3). While the state is maintained, the heel mat (2) is placed on the floor carpet (1) at a predetermined position, and the upper mold (4A) and the lower mold (4A) of the press (4) are placed as shown in FIG. 4B) and press the heel mat (2) to the floor carpet (1).

At this time, as shown in FIG. 5, the mounting recess (1B) of the carpet (1) is in positional correspondence with the hot melt adhesive (3) applied to the back surface of the heel mat (2), and Since the adhesive (3) easily reaches the bottom of the mounting recess (1B) of the carpet (1) and solidifies, strong adhesion is achieved without the need to increase the amount of hot melt adhesive (3) applied. A tight seal can be obtained. Even if the hot melt adhesive (3) is applied to the inside of the heel mat (2) by about 10 mm, the hot melt adhesive (3) does not stick out from the periphery of the heel mat (2).

In addition to the above embodiments, in the present invention, when the pile layer of the floor carpet is not composed of the heat-meltable fiber, the pile layer is cut without melting to form the mounting recess. May be.

[0013]

[Effect of device]

 Therefore, in the present invention, even in a high-class carpet having a high pile layer density and a long length, the heel mat can be firmly bonded with good sealing property without the adhesive squeezing out from the periphery of the heel mat.
