2. Description of the Related Art As shown in FIG. 3, a tongue projecting from a main body 5 of a full wheel cover 4 is formed in a concave portion 1c behind a rim hump portion of an automobile disk wheel 3 comprising a rim portion 1 and a disk portion 2. Press the engaging portion 6c of the convex piece 6 of
A full wheel cover having a structure in which the full wheel cover 4 is fitted to the disk wheel 3 is well known.

[0003] Reference numeral 7 denotes an annular spring mounted inside the convex piece 6, which is a spring for pressing the engaging portion 6c of the convex piece 6 against the rim hump recess 1c. As another prior art, an automobile wheel cap (wheel cover) disclosed in Japanese Utility Model Laid-Open No. 6-55805 is known.

[0004] This automobile wheel cover is formed of an elastic member, has a substantially dish-shaped cross section, and has an engaging portion formed on the outer periphery thereof for engaging the inside of the outer peripheral edge of the flange of the wheel. Is fitted to the outer peripheral edge of the flange.

[0005]

In the former of the above prior arts, the rim hump portion is manufactured under the standard of the tire mounting side (outer peripheral side), so that even if the rim diameter is the same size, the rim hump portion is manufactured. If the thickness is different, the concave part 1 on the back of the rim hump
The circumference of c has a difference of 2 to 4 mm. Even if the rim size is the same, it is difficult to fit a full wheel cover unless a special one is prepared for each rim plate thickness. However, there is a problem that a full wheel cover dedicated to a disk wheel must be formed for each rim plate thickness even if the rim thickness is the same.

Further, the holding shape for attaching the annular spring 7 inside the convex piece 6 is an undercut shape, and a cam-type forming die is required, so that the forming die of the full wheel cover 4 becomes complicated. There was a problem that the mold cost was high.

Furthermore, the main body 5 of the full wheel cover 4
In addition, since the tongue-shaped convex piece 6 is protruded, the depth of the outer rim portion of the full wheel cover 4 is reduced, and the appearance tends to be poor in design.

In the latter of the above prior arts, since the outer peripheral engagement portion of the wheel cover is fitted inside the outer peripheral edge of the flange of the wheel, there is a problem that the wheel cover is likely to fall off due to an impact such as a curb ride. there were.

Further, the inner dimension of the outer peripheral edge portion of the flange of the wheel has a larger standard tolerance than the dimension of the concave portion 1c behind the rim hump portion in FIG. 3, so that the fitting of the wheel cover becomes unstable. there were.

Further, since the outer diameter of the outer peripheral edge of the flange of the wheel is larger than the outer diameter of the wheel cover, there is a problem that a full wheel cover that covers the rim flange of the wheel with the wheel cover cannot be realized.

SUMMARY OF THE INVENTION An object of the present invention is to provide a full wheel cover for an automobile for a disk wheel which can solve the above-mentioned problems of the prior art.

[0012]

In order to achieve the above object, the invention according to claim 1 is directed to a method in which a rim flange passes through a back surface of a bead seat, a recessed portion behind a rim hump portion passes through a rising portion of a disk portion, and reaches a disk surface. In a full wheel cover attached to the outside of a continuous automobile disk wheel to protect and decorate the entire surface including the disk surface from the rim flange of the disk wheel, an outer peripheral design portion opposed to the rim flange and the back surface of the bead seat, and a back of the rim hump portion. A plurality of engaging projections that engage with the concave portion, an inner peripheral design portion facing the continuous portion from the rising portion to the disk surface, and a central portion facing the disk surface are formed in order. It is a full wheel cover for an automobile.

According to a second aspect of the present invention, there is provided the full wheel cover for an automobile according to the first aspect, wherein the full wheel cover is formed only of an elastic body such as a metal plate or a resin, and the engaging convex portion is formed on a rim hump portion of the disk wheel. The wheel cover is fitted to the disc wheel by engaging with the concave portion on the back.

[0014]

When the full wheel cover is mounted on the disc wheel, the entire cover is bent by pushing the outer peripheral portion of the wheel cover, and the engaging projection engages with the concave portion on the back of the rim hump portion, so that the wheel cover is fitted. You. The wheel cover is fixed by the elasticity of the entire cover.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, preferred embodiments of the present invention will be described with reference to the drawings. 1 and 2, the disk wheel 3 is formed so as to be continuous from the rim flange 1a via the bead seat back surface 1b, from the concave portion 1c behind the rim hump portion to the disk surface 2b via the rising portion 2a of the disk 2.

Reference numeral 1 denotes a rim portion, and 2 denotes a disk portion, both of which constitute a disk wheel 3. The full wheel cover 12 is formed only of an elastic body such as a metal plate or a resin, and includes an outer peripheral design portion 8, a plurality of engagement convex portions 9, an inner peripheral design portion 10, and a central portion 11, as shown in FIG. It is integrally formed in a continuous shape. A plurality of engaging projections 9 are arranged at equal intervals in a width of several millimeters in the circumferential direction of the wheel.

When the full-wheel cover 12 having such a shape as shown in FIG. 1 is applied from the outside (the right side in the drawing) of the disk wheel 3 in FIG. Slides on the bead seat back surface 1b and is pushed to the left in the figure.

At this time, the inner peripheral design portion 10 of the full wheel cover 12 is elastically deformed mainly by bending. And
When the engaging protrusion 9 is pushed until it is fitted into the recess 1c behind the rim hump portion, the engaging protrusion 9 is fitted into the recess 1c by the elasticity of the full wheel cover 12, and the full wheel cover 1
2 is fitted and fixed to the disk wheel 3.

In this state, the elastic deformation of the full wheel cover 12 is reduced, and the distortion of the wheel cover is reduced. In addition, the full wheel cover 12 is formed to have a concave shape so that the outer rim portion has a large depth.

[0020]

Since the full wheel cover for an automobile according to the present invention is constructed as described above, if the rim diameter of the disc wheel is the same size, even if the rim plate thickness is different, the bending of the inner peripheral design portion is possible. Only the degree of (curvature) and the difference in elasticity allow the same size disk wheels to be shared,
The dimensions of the full wheel cover can be unified to a few types.

Further, the structure of the full wheel cover is simple, the mold cost can be reduced, and components such as an annular spring are not required, and the number of components can be reduced, which contributes to cost reduction.

Further, the depth of the outer rim can be increased, and the effect on the design can be improved.
