Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle interior material such as a vehicle door trim having an attachment to a vehicle body.

[0002]

[Prior art]

 As an interior material for vehicles such as vehicle door trims that are equipped with attachments to the vehicle body, a plate-like main body made of a rigid urethane foam molded body with a glass fiber mat as the core material is used as the vehicle body. Japanese Unexamined Patent Application Publication No. 1-187037 proposes an integrated mounting tool for mounting. In the conventional interior materials for vehicles of this type, a rigid urethane foam molded body has a hard urethane in the meat. Since it is normal to use insert molding of a specific resin fixture such as ABS resin with good adhesiveness, the attachment strength of the fixture to the main body is insufficient and the strength of the fixture itself is also insufficient. It is enough. Also, when trying to insert mold a fixture made of polypropylene resin or metal, which is superior in strength compared to the fixture made of ABS resin, it is necessary to apply a primer treatment in advance to improve the adhesiveness. This is troublesome and expensive. In addition, all of those obtained by these conventional methods require a mounting tool having an embedding leg portion having a large surface area capable of securing sufficient adhesive strength, which results in an increase in size as a whole. However, there are problems such as being severely limited in design.

[0003]

[Problems to be solved by the device]

 The object of the present invention is to solve the above problems and to provide a fixture made of any material to a main body made of a rigid urethane foam molded body having a glass fiber mat as a core material. The purpose is to provide a vehicle interior material that is easily and accurately integrated with mounting strength at low cost.

[0004]

Means for Solving the Problems An interior material for a vehicle according to the present invention, which has solved the above-mentioned problems, requires a plate-shaped main body made of a rigid urethane foam molded body having a glass fiber mat as a core material. In an interior material for a vehicle, in which a mounting tool for mounting this on a vehicle body is integrated at a location, the mounting tool is embedded mainly in a leg portion having a locking claw and is integrated. Is entangled with the glass fiber mat.

[0005]

[Action]

 Such interior materials for vehicles are similar to the conventional interior materials for vehicles of this type, for example, when a vehicle is interiorly mounted by attaching a mounting tool to a vehicle body, a hard urethane foam molded body having a glass fiber mat as a core material is used. The fixture attached to the required location of the main body is easily detached because the locking claws formed on the legs inside the meat of the rigid urethane foam are entangled with the glass fiber mat. It can be used for a long period of time.

[0006]

【Example】

 Next, the present invention will be described in detail by taking the vehicle door trim shown in the drawings as an embodiment. Reference numeral 1 denotes a plate-shaped main body molded from a rigid urethane foam molded body 3 having a glass fiber mat 2 as a core material, and the main body 1 is attached to a required portion with an arbitrary material such as synthetic resin or metal. The tool 4 is embedded and integrated with a horizontal leg 5 having an upward engaging claw 6, and each engaging claw 6 formed at the tip of the leg 5 is the glass fiber mat. It is entangled in 2.

[0007] The thus-configured one is designed to mount a door inside a vehicle body with a fitting as in a conventional door trim for a vehicle of this type. In the present invention, however, the fitting 4 is made of glass fiber. Not only is the leg 5 embedded in a plate-shaped main body 1 made of a hard urethane foam molded body 3 having the mat 2 made as a core material, but also the leg 5 of the fixture 4 in the meat of the main body 1 Since the upward engaging claw 6 at the tip of the is entangled with the glass fiber mat 2, the fixture 4 does not come out of the main body 1, and excellent mounting strength can be secured. Further, since the attachment strength is secured by the locking claws 6 as described above, the attachment strength of the attachment tool 4 to the rigid urethane foam molded body 3 may not be sufficient. Since it is possible to use fixtures made of polypropylene resin or metal with insufficient properties without pretreatment such as primer treatment to improve adhesion, the cost for pretreatment can be saved. You can go down. Further, all of the products obtained by the conventional method were required to have a fixture having a large surface area for embedding legs so as to ensure sufficient adhesive strength, and the size of the fixture was restricted and the design was restricted. On the other hand, according to the present invention, since a small mount 4 can be adopted, the degree of freedom in design is improved.

In order to manufacture such a vehicle interior material, however, a lower mold for molding a main body 1 made of a rigid urethane foam molded body 3 is set with a glass fiber mat 2 serving as a core material in advance. The fitting 4 which has been formed is put on the glass fiber mat 2 by engaging the locking claw 6 at the front end of the leg 5 formed at the lower end thereof with the mating glass fiber mat 2 and forming a recess corresponding to the fitting 4. Since the upper dies thus prepared are matched with each other and a rigid urethane foam material is supplied by an ordinary method to form the main body 1 made of the rigid urethane foam molded body 3 and at the same time to integrate the fixture 4, the mass production can be carried out at low cost. Note that, when using a fixture 4 as shown in FIG. 2 in which a horizontal leg 5 having an upward engaging claw 6 formed on the tip of the leg end of the fixture body is projected, Although manual work is required to entangle the claw 6 with the glass fiber mat 2, as shown in FIG. 3, the locking claw 6 is formed at the tip of the leg body of the fixture body via the hinge portion 7. When using the fixture 4 in which the legs 5 are connected in series, as shown in FIGS. 4 and 5, the fixture 4 is simply locked on the glass fiber mat 2 set in the lower mold 11. A state in which the nail 6 is placed so as to come into contact with the glass fiber mat 2 and the upper mold 12 having the recess 13 corresponding to the fixture 4 is clamped, or the fixture 4 is set in the recess 13. If the upper die 12 is clamped with, the hinge portion 7 will naturally Part 5 is engaging claw 6 to expand Gerare meantime outward is facilitated more fabrication becomes to be penetrating entangled in fiberglass mat 2.

[0009]

[Effect of device]

 As will be apparent from the above description, the present invention is a fixture for attaching a plate-like main body made of a rigid urethane foam molded body having a glass fiber mat as a core material to a vehicle body and having a leg portion having locking claws. Not only is it embedded and integrated in the leg, but the locking claws of the legs are entangled with the glass fiber mat, so it is easy to accurately attach fixtures of any material to the main body with excellent attachment strength. It has the advantage that it can be used for a long period of time. Therefore, the present invention solves the problems of the conventional interior materials for vehicles of this type, and has an extremely large practical value in combination with the advantages of being easy to manufacture and providing at low cost.
