Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a vehicular ring that covers the front surface of the rim of a disc wheel.

[Prior Art] Conventionally, as a vehicle ring for decorating the front surface of the rim of an automobile disc wheel, as shown in FIG. A ring body 2 having an L-shaped cross section is used, and on the back side of the cylindrical portion 2b of the ring body, a circular arc portion that fits into the hump groove 10 of the rim is provided at the tip of a spring plate having an F-shaped cross section. An arc-shaped claw 9 having a shape 9a was fixed by welding. In addition, 13 in the figure is a tire.

Since the depth of the cylindrical portion 2b of the ring body is long enough to reach the base of the bulb 11, it is necessary to provide a notch 12 in the bulb portion as shown in FIG. The hump groove 10 is supported in pressure contact with the circular arc portion 9a at the tip thereof.

[Problem to be solved by the invention] Therefore, in the conventional vehicle ring, since the ring body 2 is locked using the hump part 10 of the rim, the arc part 9a is formed at the tip. Since it is necessary to extend the arc-shaped claw 9 to the hump part, there is a drawback that the dimension of the cylindrical part 2b in the depth direction inevitably becomes large.

In addition, since the tire valve 11 protrudes from the rim 1, the vehicle ring is attached to the tire valve 11.
It was necessary to create a shape with a relief, and a notch 12 as shown in FIG. 7 was required, making the manufacturing process extra long.

Furthermore, in the current environment surrounding automobiles, weight reduction is being strongly promoted as a measure to improve fuel efficiency.

The present invention provides a ring that has a simplified ring body and claws, reduces manufacturing costs, and is lightweight.

[Means for Solving the Problems] The vehicle ring of the present invention is a vehicle ring that covers the front surface of the rim of a disc wheel, and is formed integrally with the flange portion 2a in the depth direction from the inner peripheral end thereof. A ring main body 2 having an L-shaped cross section and a cylindrical portion 2b has an S-shaped side surface formed on both end edges of the back surface such that the curve of the lower half is inscribed in the inner circular arc portion 1a of the flange 1b of the rim. The lower end of the leaf spring material 4 that has been cut is further extended forward, and two cuts 5, 5 are made along the S-shaped curve from its tip edge.
into the lower curve of the S-shape, and bend its central part deeply downward from the middle of the extension part to form the side horizontal U-shaped clamping claw 6, and the tip edges 7, 7 of both ends are also bent downward. a plate spring material 4 which is curled into a shape, and further has triangular protrusions 3 facing downward on both sides of the plate spring material at positions corresponding to the lower ends of the S-shape;
The tip edge 7 and the upper end 8 are fixed at a plurality of equal pitches by caulking.

[Embodiment of the invention] Fig. 1 is a partial cross-sectional view showing a state in which the vehicular ring of the present invention is attached to a disc wheel, and Fig. 2 is a front view of the vehicular ring.

The ring main body 2 having an L-shaped cross section has a flange portion 2
a, and a cylindrical portion 2b integrally formed in the depth direction from the inner circumferential end, and the cylindrical portion 2b has a length located outside the tire valve 11. Between both edges of the back surface of the ring body 2, several plate spring members 4 of a constant width made of elastic metal and having S-shaped side surfaces are caulked and fixed.

FIG. 3 is a front view of the leaf spring material 4, and FIGS. 4 and 5 are cross-sectional views of the leaf spring material.

The leaf spring material 4 is formed into an S-shaped side surface so that the curve of the lower half is inscribed in the inner circumferential arc portion 1a of the rim,
The lower end of the S-shape is further extended forward, and two incisions 5, 5 are made from the tip edge along the S-shaped curve to the lower curve of the S-shape, and the center part is inserted into the extension part. At the same time, the clipping claws 6 are bent deeply downward from the middle to form the horizontal U-shaped clamping claws 6, and the tip edges 7, 7 on both sides are also curled downward, and these lower edges 7, 7 form the flange portions of the ring body 2. The upper end 8 is caulked to the rear surface of the outer peripheral edge of the cylindrical portion 2b, and the upper end 8 is caulked to the rear surface of the inner edge of the cylindrical portion 2b.

Triangular protrusions 3 are provided on both sides of the leaf spring material 4 at positions corresponding to the lower ends of the S-shape, facing downward.

[Function] When attaching the vehicle ring of the present invention to a disc wheel, the cross-sectional lateral U formed on the leaf spring material 4
When the letter-shaped clamping claw 6 is clamped to the tip of the flange 1b of the rim, the triangular protrusions 3, 3 act to bite into the inner circular arc portion 1a of the flange of the rim, and the clamping claw 6 is clamped. It is designed to strengthen the tightening force.

[Effect of the invention] The vehicle ring of the invention has a horizontal U at the lower end of the leaf spring 4.
Due to the clamping force of the letter-shaped clamping claws 6 on the rim and the biting of the triangular protrusions 3 into the rim, the vehicle will not be dislodged outward from the rim even when subjected to impact during driving.

In addition, since the leaf spring material 4 is fixed in a state in which the curve of the lower half of the S-shape is pressed against the inner circumferential arc portion 1a of the rim, it remains in a fixed position even against external force in the circumferential direction. It also has the effect of maintaining stable retention.

Furthermore, the ring main body 2 is made short with an L-shaped cross section, and the leaf spring material 4 has a substantially S-shaped cross section, and both ends are supported by both edges of the back surface of the ring main body. Since it is attached, there is no fear of it breaking or coming off, and the weight of the leaf spring material 4 itself can be reduced by using several pieces of a constant width.

In addition, the vehicle ring of this invention can be polished to shine like conventional rings, and like white ribbons on tires, the ring can also be painted to improve the quality of the suspension. The present invention provides a ring that is lightweight, inexpensive, and has a wide range of applications in terms of design.
