Description

[Detailed Description of the Invention] The present invention relates to a wheel cap whose main body is made of synthetic resin.

In recent years, in the automobile industry, there has been a rush to make cars more decorative and to make automobile parts more decorative.

In order to meet these demands, the wheel caps that are attached to the disc wheels are also made of C1 instead of the conventional metal ones.
Recently, it has been proposed to make them from synthetic resin.

However, synthetic resin hubcaps tend to lack rigidity or elasticity compared to conventional metal ones. There was a problem in that it was difficult to design a rational structure for easy removal.

Conventionally, the method of attaching a synthetic resin hubcap body to a disc wheel is generally to attach a stopper to the back of the hubcap body, and to attach the hubcap body to the disc wheel via the retainer. .

However, this method has various drawbacks.

For example, in the wheel cap 2 shown in FIG. 1, the lower end side of the stopper 3 is inserted into the hole 4a of each mounting frame 4 protruding from the back surface of the dish-shaped portion 2b of the wheel cap body 2d, and the U-shaped The tip edge of the U-shaped curved lower end 3a is engaged with the lower surface of the mounting frame 4 to prevent the dish-shaped portion 2b from slipping out radially outward, while the U-shaped curved lower end 3a is cut out from the plate wall on both sides. Shoulder parts 3c on both sides.

3c is engaged with both crotches 4b formed in the hole 4a to prevent the wheel camp from moving inward in the radial direction.Furthermore, when the wheel camp 2 is mounted on the disc wheel 1, The upper edge of the U-shaped curved upper end 3b of the stopper 3 is brought into pressure contact with the outer surface of the beat seat portion 1a of the rim 1 of the disc wheel with a constant spring pressure.

In this structure, the stopper 3 has its U-shaped curved lower end 3a compressed, and the plate-shaped portion 2 is inserted into the hole 4a of the mounting frame 4.
The mounting method is to press fit from the outside in the radial direction of b to the inside, and then expand the U-shaped curved lower end 3a outside the hole.
, 3c to both side step portions 4b, 4b and the tip edge of the U-shaped curved lower end 3a to the bottom surface of the mounting frame is difficult due to the dimensional structure, 3 has the disadvantage that it inevitably rattles, and when removing the wheel cap 2 from the disc wheel 1, the stopper 3 is attached to the rim 1 of the disc wheel.
There are problems such as scratches on the back side of the

The present invention was made in view of the above-mentioned conventional circumstances, and is of the type described above, which consists of a synthetic resin wheel cap body and a plurality of fasteners, and the fasteners are attached to the mounting frame of the wheel cap body. A wheel cap with a new structure that prevents the stopper from rattling when installed, makes it easy to attach and remove from the disc wheel, has excellent adhesion, and prevents the stopper from damaging the back side of the disc wheel rim. It provides:

Hereinafter, the present invention will be specifically described with reference to the embodiments shown in FIGS. 2 to 4.

Similarly to the conventional example shown in FIG. 1, the wheel cap 12 according to the present invention also has a dish-shaped portion 12b having a roughly round dish shape (this part may be cup-shaped rather than dish-shaped, but in this case also A plurality of mounting frames 14 (included in the concept of a dish-shaped portion) are provided along the circumferential direction on the back surface of the plate-shaped portion (included in the concept of a dish-shaped portion), preferably at equal intervals.
A stopper 13 is attached to each of the mounting frames 14 of the synthetic resin wheel cap main body 12a which is integrally formed with a wheel cap body 12a (only one of which is shown in FIGS. 3 and 4). The structure of each stopper 13 is different from the conventional example.

Each mounting frame 14 is configured in a shape that can be easily molded integrally with the dish-shaped part 12b, and its characteristics are in the general radial direction of the dish-shaped part 12b, more specifically, on the radially inner side with respect to the dish-shaped part 12b. A hole 14a is provided in the shape of a cross-sectional plate that is inclined so that the two sides approach each other.
3 and an engaging stepped portion 14c that engages with a part of the stopper 13 to prevent it from coming off.
In order to simultaneously form a hole 14b along the axial direction of the dish-shaped portion 12b.

The fasteners 13 attached to each mounting frame 14 of the above structure are made by appropriately bending a sheet metal having spring properties, and as shown in FIG.
3d in opposite directions and in a U-shape,
A pair of U-shaped protrusions 1 curved in the same direction as the U-shaped curved upper end 13b on both sides and below the U-shaped curved upper end 13b.
3c and 13c are provided.

The U-shaped curved lower end 13a of the stopper 13 is tapered toward the lower end, as is clear from the unfolded state shown by the dashed line.

The stopper 13 of the above structure is the wheel cap body 12a.
A broom 3 is attached to each attachment frame 14 as shown in FIG.

That is, the U-shaped curved upper end 13b of the stopper 13 faces inward in the axial direction of the dish-shaped portion 12b, and the lower end side of the stopper 13 is inserted into the hole 14a of the mounting frame 14 from the outside in the radial direction to the inside. Press fit into.

During this press-fitting, the U-shaped curved lower end 13a of the stopper 13 is tapered, so it can be easily inserted into the hole 14a.
In addition, it is compressed when passing through the hole 14a, and expands again when it exits from the hole 14a and protrudes into the hole 14b, so that its leading edge engages with the inner surface of the hole 14b, that is, the engagement stepped portion 14c for preventing removal. do.

At the same time as this engagement, a pair of U-shaped curved protrusions 13c.

13c engages with the outer peripheral surface of the hole 14a.

At this time, the U-shaped curved lower end 13a and the pair of U-shaped curved protrusions 13c, 13c receive reaction forces from each other and are engaged with each other with a constant spring pressure.
No wobbling within 4a.

In addition, at this time, the lower end bottom part 13e of the stopper 13 is connected to the hole 14.
A slight distance is maintained without contact with the bottom 14d of b.

The wheel cap 12, which has a plurality of fasteners 13 on the back surface of the main body 12a, is pushed in the direction of the arrow X in FIG. 3 and fitted onto the rim 11 of the disc wheel.

As shown in FIG. 3, the U-shaped curved upper end 13b of the stopper 13 fits and presses into the face of a hump 11b generally formed on the beat seat portion 11a of the rim 11.

At this time, the entire stopper 13 is pushed into the hole 14a slightly deeper than before fitting the wheel cap 12 into the disc wheel 11, and the lower end bottom 13e of the stopper 13 is pushed into the hole 14a slightly deeper than before the wheel cap 12 is fitted into the disc wheel 11.
contacts the bottom 14d of the hole 14b.

The tip edge of the U-shaped curved upper end 13b of the stopper 13 is
As shown in the figure, although it does not cut into the surface of the disc wheel, the U-shaped curved upper end 13b is entirely fitted into the groove of the hump llb, so that the wheel cap 12 is easily removed from the disc wheel 11. There is no such thing as escaping.

The present invention can be implemented in various modified forms other than the above embodiments.

For example, a pair of U-shaped curved upper ends 13b may be formed on both sides of the plate, and one U-shaped curved protrusion 13c may be formed between them, or the U-shaped curved protrusion 13c may be cut and raised to form a protrusion. It may be formed in any manner.

As is clear from the above detailed description, the wheel cap according to the present invention has a synthetic resin hub cap body attached to a disc wheel via a plurality of fasteners, and the fasteners are shaped like a flat plate. By bending the sheet metal, the upper and lower ends are bent into a U-shape, and a U-shaped curved protrusion is provided below the upper end of the U-shaped curve.
The fasteners are very easy to process and can be provided at low cost.
Moreover, to attach the stopper to the mounting frame of the wheel cap body, insert the lower end side into the hole of the mounting frame.
The tip edge of the lower end of the U-shaped curve is attached to the engagement step to prevent the hole from being removed.
Since the tip of the U-shaped curved protrusion engages the outer surface of the hole with a constant spring pressure, the stopper does not rattle, and the installation is easy to maintain regardless of the condition. Since the upper end of the U-shaped curve fits and presses against the hump of the disc wheel rim, the fastening metal has excellent adhesion to the disc wheel and does not easily come off.
Further, the surface of the rim will not be damaged by the stopper.

Further, since the U-shaped curved upper end of the stopper does not bite into the rim, the hubcap can be easily attached to and removed from the disc wheel.
