Abstract

PURPOSE:To reduce air resistance, to improve appearance, and to prevent entrance of contaminant, by a method wherein, in a wheel cover for vehicle having spoke-like appearance, plural radial recess lines are formed in the inner surface of a wheel cover body made of clear fluorescent resin. CONSTITUTION:A wheel cover body 11 is formed in a gently-sloped conical disc by the use of clear fluorescent resin, and a conical see-through part 11b, gently sloped in the direction of an outer-periphery from a central recess part 11a, is formed. Plural grooves 11d and 11e, different in depth, are formed radially from a center in the inner they cross each other. This constitution causes streaks of the rays by the grooves 11d and 11e, and enables the projection lines to be seen in a spoke-like manner through the see-through part 11b, resulting in improvement of appearance. Further, this causes formation of a flush surface, resulting in a decrease in air resistance.

The inner and outer covers 1 and 2 are concentrically stacked and fixed to the road wheel 3, giving it a spoke-like appearance.

[Problem that the invention seeks to solve]

In recent years, in order to minimize air resistance while driving, there has been a growing trend for vehicle bodies to have flush (flattened) outer surfaces, and it is desirable to have fewer protrusions, indentations, and other irregularities from the vehicle body. However, in the above-mentioned conventional wheel cover, since the spokes are exposed on the outer surface, air flow turbulence occurs around the wheel cover as the road wheel rotates, increasing air resistance, and the spokes are exposed on the outer surface. There is a problem in that dirt such as mud and dirt tends to adhere to the surface of the product, and the dirt that has accumulated is difficult to wash away with normal washing with water.

[Means for solving problems]

This invention is intended to solve the above-mentioned problems, and by providing radial grooves on the inner surface of the wheel cover body, which is formed of transparent fluorescent resin into a substantially disk shape, the outer surface of the wheel cover is flushed. To provide a vehicle wheel cover that reduces air resistance, prevents mud and dirt from being visually recognized from the outside of the wheel cover, and exhibits an excellent spoke-like appearance.

The present invention includes a wheel cover main body formed of a transparent fluorescent resin into a substantially disk shape, and a plurality of grooves formed radially from the center side to the peripheral side on the inner surface of the wheel cover main body. fl that is characterized by
This is an i-wheel cover.

[For production]

The vehicle wheel cover having the configuration described above is used by being attached to the road wheel of a vehicle with the concave groove facing the inner surface. When in use, reflections from the concave grooves of the wheel cover body made of transparent fluorescent resin form fluorescent, glittering streaks, which are visible from the outside through the wheel cover body, and are visible from the outside through the wheel cover body. It has a unique appearance. Furthermore, since the groove is covered by the wheel cover body, air turbulence does not occur. In addition, mud, dirt, etc. are not visible from the outside, and an excellent appearance can be maintained for a long period of time.

〔Example〕

Fig. 1 is a schematic sectional view showing one embodiment of the present invention, Fig. 8 is a front perspective view thereof, Fig. 3 is a back view of the wheel cover main body, and Figs. 4 and 5 are perspective views of a part thereof. , FIG. 6 is a cross-sectional view of a part of FIG. 5, and the same reference numerals as in FIGS. 8 to 8 indicate the same or equivalent parts.

The wheel cover body 11 is made of transparent fluorescent resin and is integrally molded into a roughly disc-like shape with a loose cone, and has an identification mark 12.
A gently conical transparent section 11b is formed extending outward in the outer circumferential direction from the central four parts 1.1a, which accommodates the four central sections 1.1a, and a flange section 1.1c is formed around the periphery of the transparent section 11b.
On the inner surface of b, a plurality of grooves 11d and lie extending radially from the center side to the peripheral side have different depths and are formed so as to intersect with each other.

The grooves 11d and Ile have wide portions 1.1. f, and at the intersection, one of the grooves lid intersects in a stepped manner so as to block the other groove 11e. The transparent fluorescent resin is a transparent resin tinged with fluorescence. For example, a transparent synthetic resin containing an inorganic or organic fluorescent substance is generally used, but the resin itself may be tinged with fluorescence.
