[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wheel cover having a structure in which attachment means to a disc wheel of an automobile is provided integrally with a cover body.
[0002]
[Problems to be solved by the invention]
Conventionally, a structure shown in FIG. 5 is generally used as a structure for attaching a wheel cover to a disk wheel of an automobile. That is, the wheel cover 1 is made of synthetic resin, and the engagement claws 3 (only one is shown in the figure) are integrally provided on the outer peripheral portion of the back surface side of the cover body 2 at a plurality of locations in the circumferential direction. A metal wire ring 4 is provided on the radially inner side of the engaging claw 3 so as to prevent each engaging claw 3 from being deformed radially inward, and the engaging projection 3 a of each engaging claw 3 is formed on the disc wheel 5. In this configuration, the rim 6 is engaged with the recess 6a.
[0003]
However, in the conventional configuration described above, since it becomes a mixed product of the wheel cover 1 made of synthetic resin and the metal wiring 4, it is necessary to separate them at the time of recycling, and the recyclability is inferior. Since the metal wiring 4 is required, there is a drawback that it is difficult to reduce the weight.
[0004]
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a wheel cover that can improve recyclability and can be reduced in weight.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the wheel cover of the present invention includes a cover body made of a synthetic resin that is disposed on a disc wheel of an automobile so as to cover a side surface thereof, and a cover body on the back side of the cover body. A cylindrical portion provided integrally with the disc wheel, and an elastic portion provided on the outer peripheral portion of the cylindrical portion so as to be integrated with the cylindrical portion and in a plurality of stages in the axial direction of the disc wheel. A plurality of deformable disc-shaped ribs, and the rim of the disc wheel includes a first curved concave portion and a second curved concave portion whose inner surface is concave, and a space between the first and second curved concave portions. And a plurality of disc-shaped ribs are formed to have different projecting dimensions from the cylindrical portion along the shape of the inner surface of the rim. The plurality of disk-shaped As the disk is pushed into the disk wheel, the outer peripheral portion of each disk-shaped rib enters the first and second curved recesses, presses against the inner surface thereof, and presses against the curved projection. This is characterized in that the configuration is held .
[0006]
In the wheel cover having the above-described configuration, when a plurality of disc-shaped ribs provided on the back side of the cover body are pushed into the disc wheel, each disc-shaped rib is elastically deformed, and the outer peripheral portion of each disc-shaped rib. There the inner surface of the first and second curved recess of the rim of the disc wheel, now pressed against the curved convex portion between the first and second curved recesses, thereby comes to be held in the disk wheel. In this case, since the disk-shaped ribs that serve as attachment means are disk-shaped, the outer peripheral portion is pressed against the inner surface of the rim over the entire circumference, and there are a plurality of disk-shaped ribs in the axial direction of the disc wheel. A large holding force can be obtained. For this reason, the wheel cover is maintained attached to the disc wheel without using a separate member wiring or the like.
[0007]
And since the disk-shaped rib used as the attachment means of a wheel cover is integrally provided in the cover main body made from a synthetic resin, only a synthetic resin is used as a wheel cover, and recyclability can be improved. Further, since no separate member wiring or the like is required, the weight can be reduced.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
First, in FIG. 2, the disc wheel 11 has a configuration in which a metal disc 12 attached to a vehicle and a metal rim 14 for mounting and holding a tire 13 are integrated. As shown in FIG. 1, the rim 14 includes first and second curved recesses 15 and 16 having a concave shape on the inner surface 14 b side opposite to the outer surface 14 a side on which the tire 13 is mounted, and the first and second A curved convex portion 17 which is located between the two curved concave portions 15 and 16 and is convex on the inner surface 14b side is formed over the entire circumference.
[0009]
On the other hand, the wheel cover 20 is made of a soft synthetic resin and has a disc-like cover main body 21 and a cylindrical portion projecting from the back surface 21a side of the cover main body 21 toward the disc wheel 11 side. 22 and a plurality of, in this case, five elastically deformable disk-like ribs 23a to 23e projecting laterally so as to form a plurality of steps in the axial direction of the disk wheel 11 (Refer to FIG. 3) is provided by integral molding. Among these, the cover main body 21 is formed in a disk shape that is slightly larger than the outer shape of the tip portion of the rim 14, and has a size that can cover the side surface (the upper surface in FIG. 2) of the disc wheel 11. Further, the five disc-shaped ribs 23a to 23e are formed so as to have different projecting dimensions from the cylindrical portion 22 along the shape of the inner surface 14b of the rim 14.
[0010]
Now, in the above configuration, when the wheel cover 20 is attached to the disc wheel 11, it is performed as follows.
First, the rear surface 21 a of the cover body 21 in the wheel cover 20 is opposed to the side surface of the disk wheel 11, and the disc-shaped ribs 23 a to 23 e are applied to the inner surface 14 b of the rim 14 in the disk wheel 11. Push it to the side. Then, as shown in FIG. 4, each disk-like rib 23a-23e is pushed into the disk wheel 11 side while being elastically deformed, and as shown in FIG. 1, the outer peripheral part of each disk-like rib 23a-23e is a rim. 14, the wheel cover 20 is held by the disc wheel 11.
[0011]
At this time, of the respective disc-shaped ribs 23 a to 23 e, the outer peripheral portions of the disc-shaped ribs 23 a and 23 b located on the tip end side of the cylindrical portion 22 enter the first curved recess 15 in the inner surface 14 b of the rim 14. The outer peripheral portions of the disc-shaped ribs 23c and 23d positioned in the intermediate portion are pressed against the curved convex portion 17, and the outer peripheral portion of the disc-shaped rib 23e positioned on the cover main body 21 side is It enters the second curved recess 16 and comes into pressure contact with its inner surface.
[0012]
In such an embodiment, each of the disc-shaped ribs 23a to 23e serving as the attachment means of the wheel cover 20 has a disc shape, so that the outer peripheral portion is pressed against the inner surface 14b of the rim 14 over the entire circumference, Moreover, since there are a plurality of (in this case, five) disk-like ribs 23a to 23e in the axial direction of the disc wheel 11, a large holding force can be obtained. For this reason, the wheel cover 20 can maintain the attachment state to the disc wheel 11 without using a separate member wiring or the like.
[0013]
In general, the dimensional accuracy of the rim 14 in the disc wheel 11 particularly on the inner surface 14b side is relatively low. However, in the present embodiment, the wheel cover 20 is formed of a soft synthetic resin, so that it has a disk shape. The amount of elastic deformation of the ribs 23a to 23e can be increased, and the dimensional error of the rim 14 can be absorbed by the elastic deformation. Therefore, the mounting property to the disc wheel 11 can be improved also by this.
[0014]
And since the disk-shaped ribs 23a-23e used as the attachment means of the wheel cover 20 are integrally provided in the cover main body 21 made of synthetic resin, only the synthetic resin is used as the wheel cover 20 and the recyclability is improved. it can. Further, since no separate member wiring or the like is required, the weight can be reduced.
[0015]
