Description

Clip {Clip}

The present invention relates to a clip for releasably connecting and fixing one side member and the other member, and more particularly, it is possible to reliably connect and secure the two members and to easily release the connection state by a simple operation The present invention relates to a clip which is very suitable for use in attaching a fender protector to a fender of an automobile.

Conventionally, automobile fenders and fender protectors have been attached using a resin clip (a) and a tapping screw (e) as shown in FIG.

That is, as shown in Fig. 9, the clip (a) forms a screw hole (a2) penetrating up and down in the S-shaped resin clip body (a1) having a substantially flat cross section, and the screw hole ( A tabular cylindrical portion a3 which is in communication with a2) is formed to protrude from the upper surface of the clip body a1.

The fender protector c is inserted into the first space a4 of the clip body a1, and the lock hole c1 of the protector c is coincided with the screw hole a2. Insert the connecting portion b1 of the fender b into the second space portion a5 of the clip body a1, and the lock hole b2 formed in the connecting portion b1 coincides with the screw hole a2. The fender b and the fender protector c have been fixed by screwing the tapping screw e into the tab portion a3 through the screw hole a2 and the lock holes b2 and c1 in the state.

However, in the connection fixing operation by the clip (a), the screw hole (a2) and the amount of the clip body (a1) with the fender (b) and the fender protector (c) inserted into the clip body (a1) It requires a very troublesome work that the lock holes b2 and c1 are matched and the screw e needs to be fitted while maintaining this state. In addition, when it is necessary to attach or detach the fender b and the fender protector c for repair or maintenance, the complicated work greatly reduces the work efficiency.

In addition, since the screw (e) is required in addition to the clip (a), and the screw tightening step is required, the fender (b) is disadvantageous in terms of cost and is used as a tool such as a screwdriver at the time of screw tightening. ) May be damaged. Moreover, in recent years, a fender may be formed with resin, and in this case, when the tightening degree by a screw e becomes too strong, there exists a possibility that a crack may arise in a fender.

On the other hand, various clips for connecting automobile parts without using a tapping screw have also been proposed. For example, a clip disclosed in Japanese Laid-Open Utility Model Publication No. 59-19647 can be exemplified.

As shown in FIG. 8, the clip d integrally connects a pair of sandwiching plates d1 and d2 arranged in parallel to be spaced apart from each other at predetermined intervals by a connecting portion d3. The protruding leg portion d4 is integrally formed on the lower surface of one side holding plate d1.

The clip d presses the leg portion d4 into the attachment hole f1 formed in the vehicle body f, and locks d41 formed on the outer circumferential surface of the leg portion d4 to the inside of the attachment hole f1. The radiator grille g is fixed to the vehicle body f by being engaged to the edge portion, and the edge portion of the radiator grille g is pressed between the two sandwiching plates d1 and d2 so that the radiator grille g is sandwiched by both sandwiching plates d1 and d2. In addition, the radiator grille g is attached to the vehicle body f by inserting the connecting portion d3 into the notched recess g1 formed at the edge portion of the radiator grille g, while being sandwiched therebetween. . In this case, according to the clip d, as described above, the radiator g is inserted into the recess g1 of the radiator g so that the connecting portion d3 of the clip d is inserted without causing a lateral shift. The grill g may be attached to the body f.

However, the clip (d) is to hold the radiator grille (g) only by the two sandwich plates (d1, d2), to temporarily fix the radiator grille (g) to the vehicle body (f) to the last. . Therefore, in the connection structure by the said clip (d), the radiator grille (g) cannot be reliably fixed to the vehicle body (f), and finally, the fastening work of screw fixing etc. is required.

Therefore, in the case where the fender and the fender protector are connected by using the clip d, it is impossible to reliably connect and secure both members even if it is possible to temporarily fix both members in the positioned state. Since a fastening operation such as screw fixing is necessary, the problem as described above remains.

The present invention has been made in view of the above circumstances, and is a simple operation that does not require a fastening operation by screws or the like when fixing one member and the other member such as when attaching a fender protector to an automobile fender. It is an object of the present invention to provide a clip which can reliably connect two members to each other, and which can attach or detach both members by a simple operation.
