Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an attachment device for a cap such as a wheel cap or center cap that has a rotation prevention structure.

Conventionally, among the hubcaps that are attached to the wheels of automobiles, etc., those that are fastened to the wheel with bolts, etc. at the center of the hubcap have small seats for the fastening bolts, so they are susceptible to inertia generated during driving. The wheel cap rotates due to other slight external forces, which causes the tightening bolt to loosen.

In addition, when tightening the fastening bolt, the wheel cap rotates together with the fastening bolt, which may come into contact with the tire's air injection valve and deform the valve, causing an accident such as the center of the hubcap's valve hole and the air valve. In some cases, the center did not match, resulting in an unsightly appearance.

On the other hand, center caps that are tightened with bolts at the center are generally small and the inertial force exerted by the rotation of the wheel is small. This may cause the same problem as hubcaps.

In view of the above circumstances, the present invention aims to provide a wheel cap or center cap mounting device that eliminates these drawbacks.

The present invention is a wheel cap or center cap that is fixed to the wheel at the center of the cap, and on the wheel side,
A cap characterized in that a member having planes parallel to an axis and facing each other is provided, and the cap side is provided with a surface that corresponds to and comes into contact with the opposing plane of the member near the pedestal inside the cap. It is a mounting device.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In Figs. 1 and 2, reference numeral 1 denotes a bowl-shaped wheel cap or center cap (hereinafter referred to as the cap), which has a through hole 2 and four parts 3 in the center of which a tightening bolt is inserted and abuts, and a concave part 3. A pedestal 5 protruding from the inner wall 4 of the cap 1 is formed on the back side of the cap 1 .

6 is a pair of ribs protruding from the outside of the base 5,
They each have parallel surfaces 7.

The iron surface 7 is a surface parallel to the central axis of the cap 1.

3 to 5 show a holder 11 formed into a chevron shape.

The holder 11 has a flat portion 12 on its top and a boss 13 on its back surface.

A female thread 14 is bored in the boss 13 so that a fastening bolt can be screwed through the flat part 12.

Surfaces 15 are formed on both sides of the flat portion 12, and the iron surface 1
Reference numeral 5 corresponds to a pair of surfaces 7 provided on the rib 6 of the cap 1, and consists of parallel surfaces that contact the iron surfaces 7, respectively.

16 is a pair of mounting holes, and 17 is a reinforcing rib.

Before attaching the cap 1 to the wheel, this device first performs the following steps.
For example, the brake drum 2 on the wheel side as shown in FIG.
The holder 11 is attached to the holder 1 (fixed by L16).

Next, the cap 1 is attached from above the holder 11.

In this case, the flat part 12 of the holder 11 is inserted between the pair of adhesive surfaces 7 protruding from the back side of the cap 1 so as to be sandwiched therebetween.

That is, the two are fitted with the surfaces 7 in contact with the parallel surfaces 15 on both sides of the flat portion 12 from both sides.

Next, the pedestal 5 of the cap 1 is brought into contact with the flat part 12, and both are fixed with the fastening bolts 22.

Now, even if inertia force or external force acts on cap 1,
Since the pair of surfaces 7 of the rib 6 protruding from the back surface of the cap 1 and the surfaces 15 on both sides of the flat portion 12 of the holder 11 are fitted, rotation of the cap 1 is restricted, and therefore the fastening bolt 22 is It never comes loose.

FIG. 7 shows another embodiment, in which 31 is a brake drum;
32 is a bolt, 33 is a male screw provided on the bolt 32,
34 is a tightening nut into which the bolt 32 is screwed.

The bolt 32 is provided with a flat surface 35 at the top. Now, to attach the cap 1, as in the previous embodiment, insert the opposing parallel side wall surfaces 37 of the nut 34 between the surfaces 7 of the pair of ribs 6 protruding from the back side of the cap 1. The side wall surface 37 and the surface 7 of the rib 6 are brought into abutting fit.

Next, after the pedestal 5 of the cap 1 is brought into contact with the flat surface 35 of the bolt 32, the two may be fixed with a fastening bolt 36.

Therefore, even if an inertial force or an external force acts on the cap 1, the pair of surfaces 7 of the rib 6 protruding from the back surface of the cap 1 and the pair of opposing side wall surfaces 37 of the nut 34 will Since the cap 1 is fitted, rotation of the cap 1 is restricted, and therefore the fastening bolt 36 will not loosen.

As described above, according to the present invention, even in wheel caps or center caps that are fastened at the center using fastening bolts, it is possible to prevent rotation of the cap due to inertial force and joint external forces without changing the method. Therefore, loosening of the fastening bolt can be prevented.

Further, the center of the valve hole provided in the cap can be easily aligned with the center of the valve, and the center of the valve does not shift, so that the unsightly appearance can be improved.

Furthermore, damage to the air valve due to rotation of the cap can be naturally prevented.
