Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a claw portion of a wheel ornament for decorating the surface side of a wheel of an automobile or the like, and in particular, a circular wiring can be attached to a star-shaped wheel ornament that escapes a hub nut.

[0002]

[Prior art]

 FIG. 4 is a vertical cross-sectional view showing a mounted state of the conventional wheel ornament 6. A plurality of hub nut mounting portions 2 are formed on the disc wheel 1 by counterbore, and a notch concave portion 4 into which the claw 9 of the wheel ornament 6 is fitted is formed on the inner peripheral surface of the hub hole 3. A shelf 5 is formed at the upper opening of the hub hole 3. The wheel ornament 6 has a shape in which the outer edge is cut out so as not to interfere with the hub nut, that is, a star shape, and normally five metal claw mounting holders 7 are provided on the outer periphery of the rear surface of the wheel ornament 6. In addition to being provided in a hanging shape, a spring steel claw support 8 having a convex metal claw 9 is fitted into the holder 7.

[0003]

[Problems to be solved by the device]

 The convex metal claws 9 and the metal claw mounting holders 7 have variations in manufacturing, and when the two are combined in the worst condition, the variations may be about ± 0.5 mm at maximum. There is. Moreover, if the variation of about ± 0.2 mm in the notched concave portion 4 of the disc wheel 1 overlaps with this, the variation becomes about ± 0.7 mm, which directly affects the parting of the disc wheel 1 when the wheel ornament 6 is mounted. There is also a variation in the amount of protrusion of the metal claw 9 in the height direction, that is, the outer peripheral direction, with respect to the notched concave portion 4 of the disc wheel 1 into which the metal claw 9 of the wheel ornament is fitted. As a result, some parts of the wheel ornament may have a stinging or sinking part that makes them look ugly.

In addition, in the conventional wheel ornament 6 using the metal claw 9 made of spring steel, the spring force is finally retained at the metal claw mounting holder 7 in a state where the metal wheel is attached to the disc wheel 1. The resin itself requires a certain level of strength, and it is necessary to select a crystalline resin containing 6 nylon + glass fiber from the wax slim bar, which has the drawback of increasing the material cost. However, if a crystalline resin undergoes a thermal shock test, it has the property of shrinking due to heat (recrystallization), so the holder diameter (metal claw attachment) should be taken into consideration to prevent wheel ornaments from falling off during driving. It is necessary to increase the outer diameter size), but there is also the drawback that the disc wheel 1 will be hard to mount.

[0007] Although not shown, a method in which the portion of the metal claw mounting holder 7 is formed into a spoon-shaped claw and a star-shaped wiring is provided inside the claw-shaped claw to urge the spoon-shaped claws outwardly, respectively. However, in this case, not only is the die cost for wiring molding significantly increased, but also the processing itself is complicated and the cost is high, so it is difficult to use in practice.

[0006]

[Means for Solving the Problems]

 The present invention makes it possible to use the circular wiring 10 by providing the spoon-shaped claw 11 and the wiring holder 13 inside the resin-shaped wheel ornament 6 near the outer periphery of the back surface of the resin wheel ornament, so that there is little variation in the product. The purpose is to provide a wheel ornament that can be molded with inexpensive resin.

That is, the structure of the claw portion of the resin wheel ornament of the present invention is such that a plurality of spoon-shaped claws 11 are integrally provided in a drooping shape near the outer periphery of the back surface of the resin wheel ornament 6. At the inner lower end of the claw 11, a wiring holder 13 having a recess 12 for accommodating the wiring 10 on the inner surface thereof is formed on the inner surface of the wheel ornament 6 via a connecting portion 14 so as to face the spoon-shaped claw 11. It is hung on the surface.

[0008]

[Action]

 In the resin wheel ornament of the present invention, the repulsive force when mounted on the disc wheel 1 is applied to the wiring 10 in the central portion, so that a stable elastic force can be obtained without using the conventional high-strength crystalline resin. Can be kept. Further, since the present invention does not use the metal claws 9, the above-mentioned conventional variations do not occur, and the appearance when mounted is significantly improved.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a vertical sectional view taken along the line AA of FIG. 2 showing a state where the wheel ornament of the present invention is mounted on a disc wheel, FIG. 2 is a rear view of the wheel ornament, and FIG. 3 is a spoon-shaped claw. 11 is a partially enlarged perspective view showing 11 and a wire ring holder 13 portion. FIG. The resin wheel ornament 6 is provided with a plurality of spoon-shaped claws 11 integrally formed in a drooping manner on the outer periphery of the back surface thereof. The spoon-shaped claw 11 has an inner lower end facing the spoon-shaped claw 11. As described above, the wiring holder 13 having the recess 12 for accommodating the wiring 10 on the inner surface thereof is provided on the back surface of the wheel ornament 6 in a hanging manner via the connecting portion 14 as described above. The space formed above the connecting portion 14 is necessary to prevent sink marks on the surface of the wheel ornament 6 and can be easily formed by sliding the mold laterally during resin molding. it can.

[0010]

[Effect of device]

 According to the present invention, a spoon-shaped claw 11 provided in a drooping shape near the outer periphery of the back surface and a wiring holder 13 are connected by a connecting member 14, and a wire ring 10 is provided on the inner surface of the wiring holder 13, and by the action of the wiring ring 10. Since the spoon-shaped claw 11 is biased outward via the connecting member 14, for example, a star-shaped wheel ornament 6 having a notched outer edge portion so as not to interfere with the hub nut is used. The circular wiring 10 that is easy to manufacture and inexpensive can be used. Further, when mounted on the disc wheel 1, the repulsive force is applied to the wiring 10, so that the strength of the spoon-shaped claw portion is not particularly required as in the conventional case. Therefore, a low-cost amorphous resin can be used. It is not necessary to worry about the characteristic (recrystallization) of crystalline resin, such as shrinkage due to heat. Furthermore, in the conventional wheel ornament using the metal claws 9, the outer diameter of the metal claws 9 varies in manufacturing, and the height of the convex metal claws 9 varies during assembly. However, since the present invention does not use the claw support 8, these variations do not occur, and the appearance when mounted is significantly improved.
