【Example】

 Hereinafter, embodiments embodying the present invention will be described in detail with reference to the drawings. The automobile dash silencer (hereinafter referred to as the sheet material 1) to which the clip C of this example is attached has a two-layer structure of a urethane resin layer 1a and a vinyl chloride layer 1b, and has a good cushioning property. ing. And the insertion hole 2 penetrates and is formed in the suitable place.

By the way, the clip C of this example is integrally molded of a synthetic resin material, and as shown in FIG. 1, a disc-shaped base 3 formed at a lower end thereof with a diameter larger than that of the insertion hole 2 is formed. Has been formed. A through hole 5 into which a stud bolt 4 is planted on the body B side can be loosely inserted at the center of the base 3. A shaft portion 6 is provided upright on the upper surface of the base 3 so as to surround the through hole 5. A window portion 7 having a predetermined width is formed so as to penetrate through the shaft portion 6 in the radial direction, so that the stud bolt 4 can be housed inside the shaft portion 6. Further, a pair of claw pieces 8 face each other in a direction in which the window portion 7 penetrates at the opening edge of the through hole 5, and both claw pieces 8 are elastically engaged with the stud bolt 4 as a fixing means for the body B side. Is possible.

On the upper portion of the shaft portion 6, engaging recesses 9 are provided on both side wall surfaces in a direction orthogonal to the opening direction of the window portion 7. The two engaging recesses 9 are recesses 11 that are recessed to avoid interference with the base side of the pressing piece 10, and the shaft part 6 that holds both pressing pieces 10 in the collapsed state (state in FIG. 5). As shown in FIG. 3, the engaging edges 12 are formed so as to project from the upper end edge of each of them. Is arranged (point-symmetrical arrangement).

In addition, by connecting the base side of both holding pieces 10 to the upper edges of both escape portions 11 by the thin hinges 13, from the standing state to the horizontal lying state in which the upper surface of the shaft portion 6 is closely contacted. It is possible to fold and deform, and a holding claw 14 that constitutes a holding means of the pressing piece 10 is formed on the inner surface near the tip of the holding claw 14 so as to project from the corresponding locking edge 12. Engage elastically. Further, both pressing pieces 10 are set to be substantially flush with the wall surface of the shaft portion 6 in the upright state so that they can be inserted into the insertion holes 2 of the sheet material 1, but the tip end portion is smooth. Both are curved inward with various arc surfaces. Such a bent portion serves as a sliding contact portion 10a that comes into sliding contact with the deformation guide surface 16 of the assembling jig 15, and plays a role of smoothly performing the falling deformation operation of the entire pressing piece 10. Here, the assembly jig 15 is arranged in close contact with the vinyl chloride layer 1b of the sheet material 1, that is, on the side opposite to the insertion side of the clip C. Then, the above-described deformation plan inner surface 16 is provided at a position corresponding to each insertion hole 2, and this surface is a smooth arc surface so that the deformation operation of the pressing piece 10 can be guided.

However, immediately after the sliding contact portion 10a comes into contact with the deformation guide surface 16, a stopper piece 17 is formed on the wall surface of the escape portion 11 so as to prevent the pressing piece 10 from falling backward (falling outward). , The pressing piece 10 is restricted from tilting backward more than the upright posture.

Next, the operation of attaching the sheet material 1 will be described. First, the assembly jig 15 is arranged facing the vinyl chloride layer 1b side of the sheet material 1. On the other hand, a press jig 18 is arranged on the opposite side of the sheet material 1, and a clip C is set at a position corresponding to each insertion hole 2. Then, the sliding contact portions 10a of both pressing pieces 10 are fitted into the insertion holes 2, and the press jig 18 is driven and pushed in in this state. Then, when the sliding contact portion 10a comes into contact with the deformation guide surface 16 of the assembly jig 15 and is further pushed in, the two contact pieces 10 are gradually guided by the sliding contact portion 10a being guided by the arc surface of the deformation guide surface 16. When it is deformed in the folding direction (see Fig. 4) and the pressing of the clip C is continued while the sheet material 1 is further compressed, both pressing pieces 10 are brought into a flat state in which they are closely attached to the upper surface of the shaft portion 6. Folding deformation is performed until both holding claws 14 engage the corresponding locking edges 12 (state of FIG. 5). After that, when the assembling jig 15 and the pressing jig 18 are both retracted, the clip C is temporarily attached to the sheet material 1 while the sheet material 1 is sandwiched between the base plate 3 and the pressing pieces 10.

When the clip C is attached to the sheet material 1 as described above, the attaching operation to the body B is performed. That is, when the stud bolt 4 of the body B is fitted into the through hole 5 of the clip C and the sheet material 1 is strongly pushed toward the body B side, the stud bolt 4 engages with both the claw pieces 8. Thus, the sheet material 1 is attached to the body B.

As described above, the temporary attachment of the clip C to the sheet material 1 can be performed only by inserting operation, that is, the operation can be performed from one direction to the sheet material 1, and therefore the work can be performed smoothly and quickly. You can In addition, it is easy to mechanically automate the tacking work, and it is expected that workability will be improved in this respect as well. However, of course, it is also possible to perform the work manually, in which case However, since the clip C can be temporarily attached only by inserting it if the deformation guide surface 16 is provided, the workability is improved in any case.

The present invention can be modified in various ways. For example, instead of the engagement between the holding claw 14 and the locking edge 12, a system as shown in FIG. 7 can be adopted. That is, the holding claw 14 may have a conical shape, and the shaft 6 may be provided with the locking hole 20 for elastically engaging the holding claw 14. In this case, even if an external force is applied to the pressing piece 10 in the circumferential direction, it is possible to obtain the effect of resisting this. Further, in this example, the stopper piece 17 is provided on the shaft portion 6 in order to restrict the rearward deformation of the holding piece 10, but instead of this, the inner surface of the holding piece 10 and the side of the shaft portion 6 are formed as thin connecting pieces. It is also possible to use a form of connection. Furthermore, in this example, the T-type stud bolt 4 is used for fixing to the body side, but it may be fixed by a screw type stud.
