A relative face fastener 4 forming a couple together with the engaging fastener 3 fitted on a carpet working as a male and a female is fixed on the recess by the method of double- side tape fastening, screw fastening or the like. The engaging face fastener 3 is engaged and retained on the relative face fastener 4 fixed on a molding tool.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for attaching hook-and-loop fasteners to molded interior materials such as automobiles and houses.

[0002]

2. Description of the Related Art There is a method of using hook-and-loop fasteners as a simple fastening means for interior materials which are fastened mainly to interior panels of automobiles and interior wall surfaces of houses for the purpose of decoration.

[0003] In this method, a detachable attachment / detachment fastener using a pile is attached to a necessary portion of the back surface of the interior material in a required length and size, and the attachment fastener and the male / female portion are attached to the attachment material side. The interior material is attached by engaging with a pair of relative surface fasteners.

Conventionally, this kind of attachment surface fastener is attached to an interior material by inserting a metal needle into the surface fastener as shown in FIG. 4 and bending it by penetrating the surface fastener and the interior material. It was done by tackling.

This method is simple and reliable, but on the other hand, it requires a lot of man-hours because it is a manual work, and it is easy to cause the attachment position to be rounded, and the head of the tacker needle is internally provided. It was exposed on the surface of the material and was unattractive.

In order to solve this problem, Japanese Patent Laid-Open No. 63-
215440 provides a method of attaching a surface fastener in which one or a plurality of through holes are formed in the center of the surface fastener and a hot melt adhesive is attached to the through hole.

According to this method, the tacker is abolished and the surface fastener is fixed by the hot melt adhesive, so that the problem of exposing the tacker needle head can be solved.

However, even if the hook-and-loop fasteners are fixed by this method, most of the work still requires manual labor, takes a lot of man-hours, and the mounting position accuracy is not sufficient.

[0009]

SUMMARY OF THE INVENTION The present invention has been made as a solution to this problem, and provides a method capable of accurately and firmly attaching a fastening surface fastener to an interior material without requiring special man-hours. It is provided.

[0010]

Means for Solving the Problems The means of the present invention for solving the problems is to provide a recess at a portion corresponding to a mounting position of a fastening surface fastener of a molding die for an interior material, and to provide the depression with the fastening surface fastener and the male and female. By fixing a pair of relative surface fasteners, engaging and holding the engaging surface fasteners to the relative surface fasteners, and passing and fixing the engaging surface fasteners to the interior material during molding of the interior material.

EXAMPLES Examples of the present invention will be specifically described below by taking the case of application to a floor carpet for automobile interior as an example, but the present invention is not limited thereto.

The construction of this type of floor carpet for automobiles is such that a carpet material made of synthetic fibers such as polyester or polypropylene by tufting or needling, and a thermoplastic resin such as polyethylene or polyethylene-vinyl acetate copolymer. The backing material is mainly used as a lining material and is laid by being molded.

In this method of molding a carpet, the backing material is softened by heating the carpet with a far-infrared heater or the like, and the backing material is transferred into a molding die and clamped and shaped. The cushioning material and the reinforcing material are partially fixed at the same time (or after the molding) of the carpet.

Further, fittings for attaching to a plurality of body panels are attached to the ends of the carpet, and in particular, at the front end of the carpet, the attachments on the opposing dash insulator side and the attachment surface fasteners that form a pair of male and female are attached. .

The method of attaching the fastening surface fastener is as follows:
Conventionally, in many cases, the above-described tacker is used, and there is a method using an adhesive such as hot melt, but in any case, it is done manually after molding the carpet.

According to the present invention, in the forming die for the back surface (backing material side) of the carpet, a surface shape (25 mm × 25 mm) approximately equal to the surface fastener is provided at the attachment position of the attachment surface fastener.
50mm square) and make a pair of mating surface fasteners and mating surface fasteners to be attached to the carpet in this depression by fixing with a method such as double-sided tape or screws. A hook-and-loop fastener is engaged with and held by the hook-and-loop fastener.

At this time, the attaching surface of the engaging surface fastener that is engaged and held to the carpet is the one of the molding die (without a dent).
The depth of the depression is set so that it slightly protrudes (about 1 mm) from the general surface (usually about 2 to 5 mm).

By forming the floor carpet as described above by using the molding die in which the fastening surface fastener is engaged and held at the predetermined portion, the fastening surface fastener can be fixed to the predetermined portion on the back surface at the same time when the carpet is formed. .

That is, the attachment surface of the fastening surface fastener, which is engaged with and held by the molding die on the back surface side of the carpet and is slightly projected from the general surface, is attached to the carpet inside the backing material which is softened at the initial stage of molding. It enters and is fixed by cooling and solidifying the backing material, which is a fixed state due to a so-called anchor effect, and is firmly and accurately fixed at a predetermined position on the back surface of the carpet.

The surface fastener used here is a surface fastener such as dual lock fastener (trade name), magic fastener (trade name), etc., which can be freely attached / detached using a pile, and is used in a required shape and size.

[0021] Further, in order to further secure the attachment to the carpet backing material, the surface of the surface fastener to be attached to the carpet is fluffed, and an intervening material made of fiber, resin, or the like, which easily enters the carpet backing material, is interposed. It is also possible. (Not shown)

[0022]

As described above, according to the present invention, the surface fastener can be attached to the interior material at the same time as the molding is strong and accurate at the same time as molding by the minimum change of the molding die. In addition, unlike the conventional tacker stopper, the tacker needle is not exposed on the surface so that it does not look bad, and the number of steps can be reduced.
