Description

[Detailed Description of the Invention] This invention relates to a synthetic resin hubcap that is attached to a wheel of an automobile or the like.

In recent years, wheel caps made of synthetic resin that have been colored, painted, or plated to give them a metallic appearance have become increasingly popular due to demands for greater design freedom, lower cost, and an aluminum wheel-like appearance.

The means for attaching this synthetic resin hubcap to a wheel is to provide multiple clip attachment sections along the outer periphery of the rear surface of the hubcap body, attach clips to these sections, and lock the tips of these clips to the wheel. Attachment measures were taken.

However, with this conventional attachment method, due to the thermal expansion, contraction, creep, etc. of the synthetic resin, play may occur between the clip and its attachment part, and the clip attachment of a synthetic resin wheel cap may be difficult. There was a risk that the parts would be deformed due to heat.

Therefore, it has been proposed to attach a metal ring to the clip so that the force in the center direction that occurs when the hubcap is attached to the wheel is borne by the metal ring (Japanese Patent Application Laid-Open No. 72824/1982).

However, in this case, only the clip was reinforced with a metal ring, so the effect of preventing deformation of the clip attachment part was still insufficient.

In particular, when attaching the clip, there was a risk that the portion would be deformed in the circumferential direction.

In view of the above, this invention provides a synthetic resin wheel cap in which no looseness occurs between the clip and its attachment, and in which the clip attachment of the synthetic resin wheel cap does not cause heat deformation. .

The gist of this invention is that a plurality of clip attachment sections are provided along the outer periphery of the back surface of the synthetic resin wheel cap body, and the clip attachment sections are provided with clips for securing the wheel to the wheel cap. This clip mounting part is formed with a clip receiver part that protrudes from the wheel cap body in the inner axial direction, and a support part that supports the clip receiver part, and a step part is formed at the upper end of the support part. A recess is formed between the lower surface of the clip holder and the step of the support part, and a metal ring is fitted into this recess, and the metal ring is bent at the part that contacts the lower surface of the clip holder. The synthetic resin wheel cap has a bent portion, and the clip is provided with a curved portion for preventing the metal ring covering the recess from falling off.

An embodiment of this invention will be described below with reference to the drawings.

As shown in FIGS. 1 and 2, a clip attachment part 2 is integrally formed on the outer circumference of the back surface of the synthetic resin wheel cap body 1 and projects in the inner axial direction of the wheel cap body 1. As shown in FIGS.

The clip mounting portion 2 integrally formed with the wheel cap body 1 includes a flat clip receiving portion 21 and a support portion 22 that supports the clip support portion 21 on the wheel cap body 1, and the upper end of this support portion 22 has a stepped portion. 23 is formed, and the clip receiver has a recess 24 formed between the lower surface of the portion 21 and the stepped portion 23 of the support portion 22.

Further, the clip receiver portion 21 is provided with a recess 25 for fixing the clip 4 approximately in the center thereof.

In addition, it is preferable to provide 6 to 8 clip attachment parts 2 on the outer periphery of the back surface of the synthetic resin wheel cap body 1.

The metal ring 3 is connected to the lower surface of the clip receiver part 21 and the support part 2.
It is formed into an annular shape with a diameter that allows it to fit into the recess 24 formed by the step 23 of No. 2, and the ends are welded.

Note that the end portion of the metal ring is not limited to being welded, and the clip receiver may be inserted and locked into a hole (not shown) of a metal ring locking portion provided along the portion 21.

This metal ring 3 is fitted into the recess 24 so as to come into contact with the lower surface of the clip receiver part 21 in order to prevent the clip receiver part 21 from deforming due to heat.

The clip 4 for attaching the wheel cap body 1 to the wheel is made of a leaf spring, and has a locking claw 41 bent downward at the center of the clip and projecting downward as shown in FIG. An upwardly curved portion 42 is formed, and claws 43, 43 for attaching and locking the hubcap body 1 to the wheel are formed at the tip of this curved portion 42.

In addition, both side edges have grooves 44 which are bent inward in a substantially U-shape so that the clip receiver of the clip attachment part 2 can be inserted into the part 21.
44 is formed, and a curved portion 45.45 for preventing the metal ring 3 from falling off is formed at one end so as to cover the recessed portion 24.

To attach this clip 4 to the clip receiver part 21,
Insert both edges of the clip receiver with grooves 44 and 44 formed in the section 21 and push in, and then push the locking claw 41 into the clip receiver section 21.
It is locked and fixed in the recess 25 of.

Note that the annular metal ring 3 is fitted into the recess 24 before the clip 4 is attached to the clip receiver 21.

Further, the clip receiver of the annular metal ring 3 is bent at the portion that comes into contact with the lower surface of the portion 21 to form a bent portion 31.

Note that the support part 22 is for reinforcing the clip receiver part 21 and for forming a recess 24 for mounting the metal ring 3, and its shape is not limited.

As described above, this device fits an annular metal ring into the recess formed by the bottom surface of the clip holder and the step of the support part so that it comes into contact with the bottom surface of the clip holder, and then each clip Since the force from the holder can be held evenly by the metal ring, the clip holder is prevented from creeping, reaction force of the clip secured to the wheel, repeated impact from the wheel, and heat from the wheel. It is possible to obtain a synthetic resin wheel cap in which deformation of the part is supported or prevented by the metal ring, and no looseness occurs between the clip and the part when the clip is attached.

In addition, since the metal ring is provided with a bending part, the deformation of the metal ring in the circumferential direction is prevented by preventing the metal ring from rotating and the clip holder.
