Abstract

PROBLEM TO BE SOLVED: To ensure strong clamping force without generating defect of appearance such as stringing and play by caulking and clamping a projected part formed around a caulking pin fitting part under a condition where it is embedded in a head part for stopping falling out. SOLUTION: A caulking pin 2 is projected on a molding base sheet 1 being a trim main body consisting of a thermoplastic resin and after a pin fitting part of a member 10 to be fitted is fitted thereon, a free end of a caulking pin 2 is formed into a molten and solidified head part 3 for stopping falling out to fix the member 10 to be fitted. A step part 10a is formed on the lower part of the inside of the member 10 to be fitted and positioning is performed under a condition where the curved apex part 1a of the molding base sheet 1 is brought into contact with this step part 10a and a projected part 11 for connection is formed around a caulking pin fitting part 10b. Caulking clamping is performed under a condition where this projection 11 for connection is embedded in the head part for stopping falling out. positioning between the molding base sheet 1 and the member 10 for to be fitted 10 is facilitated thereby.

2. Description of the Related Art For example, in an automobile interior material such as a door trim, a caulking pin is projected on a trim molded substrate made of a thermoplastic synthetic resin, a member to be mounted is fitted on the caulking pin, and the free end of the caulking pin is attached to the caulking pin. It has been widely practiced to fix a member to be attached by molding it on a retaining head that is melted and solidified with a high frequency wave or an ultrasonic horn (for example, Japanese Utility Model Laid-Open No. 62-114724 and Japanese Patent Laid-Open No. Hei. 2-13013
No. 0 publication etc.).

However, since the molded substrate and the member to be attached are usually made of the same material, if the caulking fastening is to be made firm, not only the caulking pin but also the member to be attached will be melted and burrs such as stringing will occur. However, there is a problem that if the caulking is weakened to avoid this, rattling occurs and it causes abnormal noise. Was not easy to set to an optimum value, which was a factor to reduce workability.

The drawing shows a case where a trim body and a lid body in an automobile door trim are caulked and fastened, in which 1 is a molded substrate which is a trim body made of a thermoplastic synthetic resin, and 10 is crimped to the molded substrate 1. It is a member to be attached as a lid body made of synthetic resin of the same material to be fastened. Then, a caulking pin 2 is provided on the molded substrate 1 so that a pin fitting portion of a member 10 to be mounted is fitted to the caulking pin 2 and a free end of the caulking pin 2 is melted and solidified to a retaining head 3. The point that the mounted member 10 is fixed by molding is basically the same as the caulking type fastening mechanism in the conventional synthetic resin product of this type.

Further, the caulking pin fitting portion 10b of the mounted member 10 is formed with through holes for inserting the caulking pins, and four connecting projections 11 are equally spaced around the through hole. As shown by the one-dot chain line, for example, when the free end of the caulking pin 2 is melted and solidified by the ultrasonic horn to form the retaining head 3, the tip of the connecting convex portion 11 is detached. By being caulked and fastened in a state of being embedded on the lower surface side of the stopper head 3, the mounted member 10 is firmly fastened to the molded substrate 1 without rattling or the like. That is, according to the present invention, unlike the prior art in which the free end of the caulking pin is melted and solidified on the peripheral portion of the caulking pin fitting portion in a plane and wholly, the connection convex portion 11 is melted and solidified in spots. Therefore, even the mounted member 10 is not melted to generate burrs such as stringing, and a strong fastening force is secured.

Incidentally, the caulking pin fitting portion 10b of the member 10 to be mounted is usually formed with a through hole corresponding to the caulking pin 2. However, as shown in FIG. The cutout groove 12 may be formed as a cutout groove. In this case, the opening side of the cutout groove 12 may be inserted into the caulking pin 2 so that the cutout groove 12 can be assembled. It is possible to greatly expand the degree of freedom in design and secure a strong fastening force. Further, as shown in FIG. 3, it is needless to say that the invention can be similarly applied to a type in which the caulking pin 2 has a fin 4 for fixing an attached member at a lower portion thereof.

Next, the caulking fastening process of the vehicle door trim will be briefly described. As shown in FIG. 4, each caulking pin 2 is fitted into the caulking pin fitting portion 10b of the member 10 to be mounted, and It is supported by an arm 21 which can be rotated and moved up and down from the side through pedestals 20a and 20b, and ultrasonic horns 22a and 22b melt and solidify the free ends of the caulking pins. In this case, a stepped portion 10a is formed in the lower inner portion of the mounted member 10, and the stepped portion 10a and the curved front end portion 1a of the molded substrate 1 are simply brought into contact with each other to position the molded substrate 1. The positioning with the mounting member 10 can be ensured, and at the same time, the caulking pin 2 and the caulking pin fitting portion 10
Positioning with b can also be performed. In the fitting step, the caulking pin fitting portion 10b is cut into the groove 1
The number is 2 and the opening side of the cutout groove 12 is simply inserted into the caulking pin 2 so that the caulking pin 2 can be assembled in a simple and short time.

By setting the fastening force of the ultrasonic horn to be slightly weakened during the crimping step, crimping is performed with the connecting projection 11 embedded in the retaining head 3, and the thread is tightened. Burrs such as pulling and rattling will not occur, and a strong fastening force will be secured.
In addition, as described above, the connecting projection 11 has the retaining head 3
Since the caulking is performed in the state where it is embedded in the housing, a sufficiently strong fastening force can be secured even if the control conditions such as the temperature difference of the outside air and the pressure change of the ultrasonic horn are wide, which is difficult to achieve with conventional methods. The fastening work can be easily performed without setting a proper fastening force.

As is apparent from the above description, according to the present invention, it is possible to secure a strong fastening force without causing appearance defects such as stringing and rattling, and to set the caulking fastening force. Is also easy and can greatly improve workability. Therefore, the present invention is extremely large in that it contributes to the development of industry as a caulking type fastening mechanism in a synthetic resin product that eliminates the conventional problems.
