Abstract

(57) [Summary] [Purpose] The object of the present invention is to firmly bond a heel mat to a high-grade floor carpet having a high pile layer and a long length. [Structure] A plurality of holes 1 are provided at predetermined locations on the floor carpet 1.
B is formed, and the heel mat 2 is adhered by the hot melt adhesive 3 at the position of the hole 1B.

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 back surface periphery. 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 heel mat (2) and the floor carpet (1) are hermetically 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-mentioned conventional problems, the present invention provides a plurality of holes (1B) at predetermined locations on a floor carpet (1), and an adhesive agent is used to attach a heel mat (2) to the holes (1B). It provides a mounting structure for the heel mat (2) adhered by (3).

[0007]

[Action]

 In the present invention, since a plurality of holes (1B) are provided at predetermined places on the floor carpet (1), the adhesive (3) flows into the holes (1B) when the heel mat (2) is bonded. , Anchor effect improves adhesive strength and hermeticity.

[0008]

【Example】

 1 to 5, the floor carpet (1) has a pile layer (1A), and a plurality of holes (5A) are arranged on the upper surface as shown in FIG. It is placed on the pedestal (5) and drilled by a drilling jig (4) having a plurality of piercings (4A), and as shown in FIG. 2, a predetermined position, for example, the driver's seat side shown in FIG. Provide a plurality of holes (1 B) at.

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, and the adhesive (3) is softened. While maintaining the state, the heel mat (2) is placed on the floor carpet (1) at a predetermined position, and as shown in FIG. 4, the upper mold (7A) and the lower mold (7A) of the press (7) ( 7B) and press the heel mat (2) to the floor carpet (1).

At this time, as shown in FIG. 5, the hole (1B) of the carpet (1) is positionally corresponding to the hot melt adhesive (3) applied to the back surface of the heel mat (2), Since the adhesive (3) flows and solidifies in the hole (1B), strong adhesion and good airtightness can be obtained by the anchor effect without increasing the coating amount of the hot melt adhesive (3). The hot melt adhesive (3) does not run off the edge of the heel mat (2) even if it is applied about 10 mm inward from the edge of the heel mat (2).

[0011]

[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.
