JPS5837685Y2 - Center cap mounting device - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an attachment device for a center cap that covers the center portion of a wheel disc.

Conventionally, decorative hubcaps that cover the entire wheel and center caps that cover only the center part have been attached to the wheel discs of automobile wheels, etc., but in both cases, the hubcap is attached to the wheel disc. For the purpose of attaching the wheel cap to the wheel cap, a mounting claw was attached to the wheel cap body by caulking or screwing.

In order to obtain sufficient safety performance, this holder used to be heavy and expensive, but recently, the undercarriage part has been made lighter to save fuel and improve comfort. There is a trend towards simplifying the installation means with the aim of reducing costs in order to absorb the increase in safety and pollution control costs.

In view of these trends, the present invention provides a center cap mounting device that is advantageous in terms of weight, is inexpensive, and prevents detachment due to vibration impact during rotation.

An embodiment of the present invention will be described below based on the drawings.

Fig. 1 shows a perspective view of the mounting claw 2, in which a U-shaped notch is provided in the center of the flat strip, this portion is bent downward to provide a hook-shaped elastic claw 4, and one end of the flat plate is provided with a hook-shaped elastic claw 4. A retaining part 3 is formed by forming a diagonally upward hooking part 5 on one end, bending the other end upward into an R-shape 6, and forming an S-shape at the tip.

Note that 13 is a reinforcing flange provided on the central side of the flat plate for the purpose of increasing the strength of the mounting claw.

Fig. 2 shows a cross-sectional view of the center cap attached to the wheel disc using the above-mentioned mounting claw.The hook-shaped elastic claw 4 provided below the center of the mounting claw 2 is Insert into the round hole 11 of the reinforcing rib 10 formed in advance on the wheel disc 1, and attach the hook part 5 provided diagonally upward at the rear end of the J mounting claw 2 to the wheel disc 1.
At the same time, a plurality of R-shaped portions 6 of the front end engaging portion are elastically fitted to the inner peripheral edge of the reinforcing bead 7 of the wheel disc.

On the other hand, the center cap 14 has a curl 12 formed inward at its outer peripheral end so that it can fit with appropriate elasticity into the outer recess of the S-shaped engaging portion 3 of the mounting claw 2. has been done.

In the present invention, the outer circumferential curl portion 12 of the center cap 14 is elastically fitted into the plurality of attachment claws 2 fixed to the wheel disc 1 as described above.

In addition, FIG. 3 shows another embodiment, in which the groove in which the hooking part 5 at one end of the mounting claw 2 fits is not annular, but a plurality of cut-out parts 15 are provided in the wheel disc. Locking groove 10
The hole 17 is also provided outside the cut-and-raised portion, not in the reinforcing lip.

As described above (the center cap mounting claw according to the present invention can be manufactured from a flat plate using a progressive press or a transfer press, etc., and since the center cap can be attached and held on this claw, it is not possible to use the conventional center cap holder). It is superior in terms of cost and weight reduction compared to those with mounting claws all around the circumference, and in the automobile industry, where labor saving and cost reduction are in demand,
It has particularly great industrial applicability.
