Description

[Detailed Description of the Invention] The present invention relates to a fixing device for attaching a molding to be decorated on the side surface of an automobile body.

Conventionally, when attaching moldings to a car body, one known method was to install stud bolts in the car body in advance and attach them to scaffolding, and another method was as shown in Figure 1. Similarly, there is a piece 1 that fits into the pocket a of the molding A, a bolt 2 for the hole to be drilled into the vehicle body B, a nut 3 for tightening the bolt, a washer 4, etc.
A method of attaching using a clip that combines a plurality of parts is known.

However, the former method requires welding work and the molding must be inserted by sliding it through a large number of bolts, which can sometimes damage the painted surface of the car body or prevent smooth installation. Additionally, there were restrictions that made installation impossible depending on the location.

In the case of using the latter clip, as shown in the figure, after assembling the piece 1 through a bolt, fit the piece 1 into the pocket a of the molding, and insert the protruding bolt 2 into the through hole of the car body. It is installed by tightening the nut 3 from the back side, but as shown here, there are a large number of parts, and since they have to be assembled together, it is difficult to work, and the metal material is used with exposed parts. However, it had the disadvantage of causing rust and staining the car body.

The present invention was devised in view of these conventional defects, especially the latter defect mentioned above.The main part of the clip is molded from synthetic resin, and the elasticity of the material allows it to be firmly attached to the vehicle body. It is an object of the present invention to provide a molding clip which is substantially made into a single piece and whose handling and workability are dramatically improved.

The following drawings show a specific example of the present invention, and the present invention will be explained in detail based on these drawings. , 4 is a sectional view showing the state of use, and the reference numeral 10 in the drawing
1 is the head mainly consisting of the molding clip, 11 is the leg, 1
2 indicates a tightening screw.

The head 10 is formed in the shape of a rectangular plate, and both edges are curved in one direction (downward) around the center of the head 10 to form an arched cross section. The leg portion 11 extends from the center of the lower surface of the head.

The leg part 11 is molded integrally with the head part and has a cylindrical shape, and a hollow part at its axis passes through the head part 10 and has an opening 13 upward.

A pedestal part 14 is formed at the base end of the leg part with a diameter larger than that of the main body part, and several slits 15 are formed along the length direction on the circumferential surface of the leg part.

The slits 15 are formed in a vertically elongated manner while leaving the circumferential surface at the end of the leg until reaching the pedestal 14, and are provided so as to divide the circumferential surface of the leg into a plurality of parts with a constant interval between the slits. be.

In this embodiment, four slits are provided to divide the circumferential surface of the leg into four parts.

On the other hand, the tightening screw 12 is a normal screw having a head 12a, and is inserted into the hollow part of the leg 11 with the lower surface of the screw head 12a abutting the leg end.

When this tightening screw is not in use, the tip of the shaft is long enough to reach the base end of the leg where the slit 15 is not provided, and the thread of the screw is on the inner wall surface of the hollow part of the shaft of the base end. It is screwed in such a way that it snaps into place.

As described above, the fixing device of the present invention has a leg 1 attached to the lower surface of the head 10.
The head 10 and the legs 11 are integrally molded from a thermoplastic synthetic resin material.

The tightening screw 12 is introduced by molding the head and leg parts and then screwing them into the hollow part from the leg end, or by embedding them at the same time as the molding.

In this case, considering cost and productivity, in the latter case, in other words, if the tightening screw 12 is placed in the mold and integrally molded when molding the head 10 and the leg 11, the effort of screwing can be saved. is advantageous.

Next, the method of using the fixing device of the present invention formed in this manner will be explained. First, the head 10 is inserted from the end side into the pocket a of the molding A formed in a C-shape in cross section, and both ends are molded. Assemble by engaging the folded parts on both edges of A.

After doing so, the leg portion 11 protrudes toward the opening side of the pocket portion a.
(see Figure 3), then press the top of molding A to prevent the leg from coming out and expose the leg end. The molding can be fixed by twisting and tightening the head 12a of the tightening bolt 12 with a screwdriver.

That is, when the tightening bolt 12 is twisted, at least the threaded part at the tip enters into the hollow part since it is injected into the inner wall surface of the hollow part of the leg part, and accordingly, the head part 12a is attached to the leg part. In order to crush the leg part 11 in the axial direction by compressing the end, when the leg part 11 can no longer withstand this pressing force, the divided piece of the leg peripheral surface provided with the slit 15 bends in a dogleg shape and expands radially. This is because it forms a tsuba (see Figure 4).

In this case, when the tightening bolt 12 is tightened, the circumferential surface of the leg expands, and at the same time, the head 10 on the opposite side of the vehicle body, that is, the front side, is attracted, so that the molding A is firmly fixed to the surface of the vehicle body. It turns out.

In this embodiment, the pedestal section 14, which is also provided at the base end of the leg, is attracted and press-fitted to the opening of the through hole a, so that the through hole can be sealed.

In addition, FIG. 5 shows another embodiment in which the above-mentioned sealing effect is further ensured, in which an umbrella-shaped collar 16 is integrally extended from the edge of the pedestal portion 13, that is, the peripheral edge of the abutting surface with the vehicle body B. When the tightening bolt is tightened, this collar 16 is pressed against the surface of the vehicle body to cover and seal the through hole a.

The present invention has been explained above based on the illustrated embodiment, but the fixing device of the present invention only requires fitting the head 10 into the molding A, passing the leg 11 through the through hole a, and tightening the tightening bolt 12. Since the molding can be fastened by the above-mentioned work, the workability is dramatically improved compared to the conventional method, and the tightening bolt 12 is essentially embedded in the leg and becomes a single piece. Therefore, it is easy to handle during use and is extremely advantageous in terms of storage management.

Of course, since the fixing device of the present invention can be integrally molded including the tightening bolt as described above, it is easy to manufacture and has the advantage of being suitable for mass production.

In addition, the head and legs utilize the elasticity of the synthetic resin material to secure the moldings, so they can be secured without wobbling, and even if there is variation in the tightening of the tightening bolts, this difference can be avoided. Since the elastic absorbs the material, there is no risk of it coming loose during use, so it has the advantage of being safe to use.

Furthermore, as mentioned above, since the through holes through which the legs pass are sealed from the surface side, it is effective to prevent rainwater from entering and to prevent rust from forming through the through holes.
