[0002]

2. Description of the Related Art FIG. 9 shows a known molding fixing clip for fixing a molding to a body panel of an automobile. In FIG. 9A, the molding 2 fixed to the body panel 1 is shown in a cross section, and extends long in the direction perpendicular to the paper surface of FIG. The inner holding edges 3 of both edges of the molding 2 are previously locked with the molding holding portions 6 of the clip body 5 at a plurality of predetermined locations. Clip body 5
Comprises a molding holding portion 6 and a pin 7 extending from the molding holding portion 6. A hollow bush 9 is inserted into the mounting hole and fixed to the body panel 1. The pin 7 of the clip body 5 of the molding 2 is indicated by an arrow 10 in FIG.
As shown in (1), the clip body 5 is pushed into the bush 9, and the clip body 5 is fixed to the bush 9, whereby the molding 2 is fixed to the body panel 1. FIG. 9 shows the state after fixing.
It is shown in (B). In addition, since the clip body 5 is attached to a plurality of predetermined locations of the molding 2, the respective pins 7 are pressed in accordance with the bushes 9 on the body panel 1. In this operation, since the operator simply holds the molding 2 and pushes the pin 7 in accordance with the bush 9, the work of attaching the molding is simplified.

[0003]

In the above conventional clip for fixing a molding, since the bush 9 is attached to the body panel 1 only by being pushed into the body panel attachment hole, the mounting hole of the body panel 1 is sealed. Is not enough. Therefore, water such as rain sprayed from the outer side of the molding 2 penetrates into the back surface of the body panel (the lower surface in FIG. 1A) from the mounting hole where the bush 9 is mounted. Rusting the body panel or infiltrating water into other parts. In addition, in the work of attaching the molding, the plurality of clip bodies 5 are held in advance at the designated positions of the molding 2, and then the pin 2 of the clip body 5 is
Is inserted into the corresponding bush 9, but the positioning of the pin and the bush is a difficult operation due to a shift in the holding position, a pitch shift, or the like, which has led to a failure in fixing.

Accordingly, an object of the present invention is to increase the sealing of the mounting hole of the body panel, eliminate the need for troublesome alignment in mounting the molding, and align the center of the clip with the center of the mounting hole to thereby determine the accuracy of the mounting position. It is an object of the present invention to provide a clip for an automobile which maintains a high level.

[0005]

According to the present invention, there is provided, in accordance with the present invention, an automotive clip for fixing a component such as an outfitting component for an automobile to a body panel, comprising a metal blind rivet and a plastic clip. The blind rivet is composed of a hollow cylindrical rivet body having a flange formed at one end thereof, and a mandrel extending through the rivet body, the mandrel being opposite to the flange of the rivet body. An enlarged diameter head is formed at an end and a small diameter portion that can be broken is formed in the middle. The clip body has a hollow shaft portion for receiving the rivet body, and a clip portion formed at one end of the shaft portion to form the rivet body. It comprises a flange and a hollow component fixing portion for receiving the mandrel, and the component fixing portion is formed between the surface on which the flange of the rivet body is seated and the body. A rivet body of the blind rivet, the rivet body of the blind rivet being formed of a seating portion having an opposite surface to be seated on the flannel, and a component holding portion formed integrally with the seating portion and locking the component to hold the component. A clip is provided, wherein the blind rivet and the clip body form an assembly with the flange of the rivet body inserted into the shaft portion and seated on the seating portion of the clip body.

[0006]

In the clip of the present invention, the mandrel portion projecting from the flange of the rivet body is gripped by the nose of the blind rivet fastening tool, and the molding fixing clip is held by the nose of the fastening tool. The clip is moved as it is to a mounting hole at a predetermined position on the body panel, the shaft of the clip body is inserted into the mounting hole, and the clip is pushed until the seating portion of the clip body comes into contact with the body panel. When the fastening tool is operated in this state and the mandrel is pulled so strongly that it breaks at the small diameter part, the enlarged head of the mandrel begins to deform so that the rivet body part expands, and the mandrel continues to be pulled. The enlarged diameter part moves toward the flange while increasing,
This enlarged portion cooperates with the seating portion of the clip body on which the flange is seated, and begins to strongly clamp the body panel.
Since the shaft portion of the clip main body outside the rivet main body is also expanded in diameter by expanding the rivet main body, the enlarged diameter portion of the clip main body shaft portion and the clip main body seating portion include the mounting hole of the body panel. Strongly adheres to both sides of the panel near. In addition, since the diameter of the rivet main body is evenly increased in the mounting hole in the diameter increasing operation, the center of the rivet main body (and, consequently, the center of the entire clip) coincides with the center of the mounting hole. The clip fixed to the body panel may be fitted with a fitting part such as a molding, and the locking portion may be pushed into the clip main body while being aligned with the component holding portion of the clip body.

[0007] Therefore, the clip for molding fixing is securely and strongly fixed to the body panel by deformation of the rivet main body of the metal blind rivet without operating the fastener and only by operating the fastening tool. Since it is made of plastic, the sealing of the mounting hole is securely and strongly maintained, and the watertightness is high, so that water such as rain from the molding side does not leak to the back surface of the panel, and there is no rust. In addition, since the connection is performed by being sandwiched from both sides by the clip flange portion whose diameter is enlarged by the rivet body of the metal blind rivet and the clip flange, the clamping force is high and stable. Furthermore, the work of attaching the molding also eliminates the need to previously hold the clip in the molding, eliminates the displacement of the holding position and the pitch, and pushes the molding onto the molding holding portion and pushes in as it is.
It can be mounted very easily without any difficulty in alignment. Also, in the operation of fastening the blind rivet, the center of the rivet body and thus the center of the entire clip coincides with the center of the mounting hole, so that the mounting accuracy of the clip is kept high.

In the above-mentioned clip for molding fixing, the seating surface of the rivet body flange of the seating portion of the molding fixing portion can be formed so as to protrude from the outer edge toward the center, and the axis of the mandrel is inclined. Even if the rivet body flange is tilted, the body panel seating surface maintains the posture in contact with the body panel, thereby
Even if the mandrel axis is shaken during the fastening operation of the fastening tool, the clip body is securely fixed to the body panel, and the clip is mounted in a posture perpendicular to the body panel. Position accuracy is improved. Also, the hollow shaft portion of the clip body is formed in a shape with a closed end so as to seal the rivet body, and a protruding portion extending in the longitudinal direction is formed on the inner wall of the tip so as to frictionally engage with the rivet body. In addition, high watertightness can be obtained, and the connection between the blind rivet and the clip body before fastening can be strengthened. As parts to be attached,
Typically, there is a molding, and when attaching the molding to the body panel, the molding holding portion of the clip body is formed by a wall standing upright from the outer edge of the seating portion, and on the outer surface of the wall,
A locking shoulder for receiving and locking the inner bent edge of the molding can be formed, and the surface of the locking shoulder on the front side in the insertion direction can be formed with a gentle slope, thereby facilitating the pressing operation of the molding. it can. Also, when mounting the molding, the component holding portion of the clip body, the wall body standing upright from the outer edge of the seating portion,
An elastic piece extending outward from the wall may be formed to hold both edges of the molding by the elastic piece.
The component to be attached may be composed of a member forming the design surface and a locking piece attached to the member, or may be an integrally molded plastic product.
