Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wheel cover, particularly the structure of a portion of the wheel cover that engages with a road wheel.

Conventionally, as a system for locking a wheel cover to a road wheel, a system using the elastic force of a ring-shaped wire is known, as shown in Japanese Patent Application Laid-open No. 51-143228.

As shown in Figure 1, a shelf A is formed on the back surface of the outer circumferential side of the wheel cover, a hole B is formed in this shelf A, and a ring shape is formed in the hole B as shown in Figure 2. The protruding part P of the wire W, which has been bent so as to project outwardly, is inserted from the inside so that the protruding part P protrudes outward from the hole B. The tip side of this protrusion P is adapted to engage with a road wheel.

Both ends of the wire W are connected by caulking or welding, and the force acting outward of the wire presses the tip of the protrusion P against the inner wall of the road wheel, and this frictional force locks the wheel cover H. It is something to do.

However, according to the above method, it is necessary to shape the protrusion P by deforming the wire W, which is relatively hard and has a high elasticity, and this operation becomes complicated and costs are high.

In addition, it is not easy to insert the protrusion P into the hole B and attach the wire W to the shelf A, and the end of the wire W must be connected by caulking or welding. It also becomes complicated.

In addition, since the protruding part P protrudes in a substantially triangular shape, its tip side comes into point contact with the road wheel, which reduces the frictional force against the road wheel and makes it easier to separate from the road wheel. It has various drawbacks, such as the need for other parts to prevent idling.

An object of the present invention is to eliminate the above-mentioned drawbacks by providing a locking piece that is pressed outwardly by a wire on the shelf, and will be described in detail below using examples.

Figures 3 to 9 are simplified configuration diagrams showing one embodiment of the wheel cover according to the present invention. In each figure, 1 is a disc-shaped wheel cover with various designs, and is press-molded from a metal plate. A rectangular shelf part 2 is formed near the outer periphery of the rear surface of the shelf part 2, which is shaped by a method such as injection molding or injection molding of synthetic resin, and protrudes in a direction substantially parallel to the axle. A step portion 3 is formed on the inside of the upper portion, and a hole 4 extending in the outer circumferential direction is formed on the upper side of the shelf portion 2.

A locking piece 5 consisting of a base 51 and a protruding piece 52 is provided in the hole 4.
The protruding piece 52 is inserted, and the end 53 side of the protruding piece 52 protrudes from the outside of the shelf 2, and the base 51 is installed on the step 3.

The inside of the base 51 has a groove 7 extending along the circumferential direction into which a part of the ring-shaped wire 6 shown in FIG. 68 is formed in the same direction as the protruding piece 52 and with a constant depth.

The wire 6 is formed into a ring shape, bent so that both ends thereof face outward, and the bent portions m are abutted against each other.
By inserting the wire 6 into the hole 8 of the locking piece 5 in
can maintain a ring-shaped shape, and the part of the wire 6 other than the abutting part n is inserted into the groove 7 of the base 51 of the locking piece 5 on the other shelf, so that it can be easily removed from the base 51. It is set to not.

This wire 6 always applies an outward force to the locking piece 5, and the tip side 53 of the protruding piece 52 always comes into pressure contact with the inner wall Y of the road wheel H, as shown in FIG. 8, so that it does not come off easily. .

In this case, the surface shape of the tip side 53 of the protruding piece 52 is
As shown in the figure, the protruding piece 52 of the road wheel H is formed so as to be in close contact with the inner wall surface Y of the portion to be engaged, and is in line or surface contact, thereby preventing it from easily separating from the road wheel H.

According to the above structure, the protruding piece 52 of the locking piece 5 pressed outward by the wire 6 comes into pressure contact with the inner wall surface of the road wheel, thereby reliably fixing the wheel cover.

In this case, the shape of the wire 6 is simply a ring, and unlike in the conventional case, a part is deformed outward and no protrusion is formed, making it easy to manufacture the wire and also to set the wire in the wheel cover. Since it is only necessary to fit the wire into the groove 7 formed in the base 51, the installation work of the wire 6 is facilitated.Furthermore, a bent portion is formed at the end of the wire 6, and the bent portions are butted against each other. It is only necessary to insert the wire into the hole 8 of the locking piece on any shelf, eliminating the need for welding and caulking as required in the past.Furthermore, the locking piece 5 is a separate part from the wire 6. By molding the locking piece 5 by injection molding, for example, the surface shape of the tip 53 side of the protruding piece 52 can be set to any desired shape, and by molding it into a shape most suitable for the inner wall of the road wheel, The wheel cover can be engaged with the wheel cover with a large frictional force, and a highly reliable wheel cover can be obtained.

Furthermore, since the frictional force against the road wheel is increased, no other parts are required to prevent slippage, resulting in low cost.

In addition, in the present invention, the base 51 of the locking piece 5 on each shelf
Although the hole 8 has been described as being formed in the locking piece 5 of the shelf portion where only the abutting portion 1 of the bent portion of the wire 6 is to be fixed, the hole 8 may be formed only in the locking piece 5 of the shelf portion.

Further, a groove may be formed on the tip 53 side of the protruding piece 52 of the locking piece 5 to increase the frictional force against the road wheel.

As explained above, according to the present invention, a shelf is formed on the back side of the wheel cover, projecting in a direction parallel to the axle, and a hole extending outward is formed in this shelf. A locking piece that is pressed outward by a ring-shaped wire is inserted, and the tip of this locking piece protrudes from the hole so that the tip comes into pressure contact with the road wheel, thereby reducing the locking force against the road wheel. There are various effects such as eliminating the risk of the wire becoming large and easily coming off or spinning idly, and making it extremely easy to attach or manufacture the wires and the like.
