Description

[Detailed Description of the Invention] The present invention mainly relates to a fixing device for attaching a vehicle wheel catch made of synthetic resin to a wheel.

Recently, synthetic resin wheel covers for automobiles and other vehicles have been widely used instead of metal ones because they are used for decorative purposes and can be designed in a variety of ways, and they also have the advantage of reducing weight. became.

On the other hand, with the development of expressways, the speed of automobiles has increased, and accidents involving wheel covers falling off pose a risk of causing serious accidents.

Therefore, it is highly recommended to securely attach such synthetic resin wheel covers to the wheels to prevent them from falling off! The need for skirts is increasing.

Conventionally, many fixing devices of this type have been known, in which elastic clips are provided at several locations on the circumference of a wheel cover and the wheel cover is fixed to the wheel using the clips.

However, since all of these methods are provided with clips at only a few locations, they have the following drawbacks.

1. Because the contact surface of the part caught on the wheel is small,
The rigidity of the hook part is increased to make the fitting part more sturdy.In other words, when the wheel and wheel cover are attached, a strong local pressure force is applied to the part, which can cause squeaks when driving. As the spring stiffness increases, the spring deflection characteristics decrease, and as the tips of the hooking claws wear out, the adhesion force decreases extremely.

Therefore, when initially attaching and detaching the wheel cover, an extremely large amount of force is required to remove and attach the wheel cover, and after repeated use, the wheel cover easily comes off due to an extremely small external force.

2. Types of hooks that dig into the wall surface of the wheel can damage the wall surface, cause rust to develop on the wheel, and as the corrosion progresses, there is a possibility that safety will be extremely compromised.

The present invention eliminates these drawbacks, securely fixes the wheel cover to the wheel, and allows for appropriate removal and removal when attaching and detaching the wheel cover.
The object of the present invention is to provide a fixing device for a vehicle wheel cover that can maintain a constant mounting force over a long period of time and is inexpensive to manufacture.

Hereinafter, an embodiment illustrating a vehicle wheel cover fixing device according to the present invention will be described.

1. First embodiment In FIGS. 1 and 2, d is a wheel rim, and 1a is a wheel rim.
is a hump portion of the wheel rim, that is, a groove-shaped recess provided annularly in the wheel 1.

2 is a wheel cover, 3 is a standing wall, wheel cover 2
It is formed into a more protruding annular shape.

Reference numeral 4 indicates a spring positioning rib, and reference numeral 5 indicates a spring holding rib, both of which protrude radially and alternately on the circumference of the wheel cover 2.

Reference numeral 6 denotes a band-shaped leaf spring, which has a bent tip 6a as shown in FIG.
are continuous alternately, and when attaching the band-shaped leaf spring 6 to the wheel cover 2, the recess 6c corresponds to the spring positioning rib 4,
The L-shaped bent portion 6b faces the spring holding rib 5.

7 fixes the band-shaped leaf spring 6 to multiple locations on the cylindrical surface of the upright wall 3 with caulking rivets, and the back of the tip bent portion 6a of the band-shaped leaf spring 6 is attached to the hump q of the wheel rim, 1. a to secure the wheel cover 2 to the wheel rim 1.

Note that a locking screw nut may be used instead of the caulking stud 7.

2. Second Embodiment As shown in FIGS. 4 and 5, the difference from the first embodiment is that a locking portion 9 for screwing the band-shaped leaf spring 6 to the wheel cover 2 is provided protrudingly. be.

As mentioned above, there are various ways to fix the band-shaped plate spring 6 to the wheel cover 2, but in all of them, the band-shaped plate spring 6 is securely fixed to the wheel cover by caulking studs or screws at multiple locations around the circumference as appropriate. The back part of the tip bent part 6a is locked to the hump part 1a of the wheel rim, and the wheel cover 2 is fixed by its elasticity. , to supplement the strength of the spring.

In the device of the present invention configured as described above, when the band-shaped plate spring 6 is sequentially fitted to the wheel force), <-2, the spring positioning rib 4 is fitted into the recess 6c at the base of the band-shaped plate spring 6. The band-shaped plate spring 6 can be easily guided to a proper position and fixed to the wheel cover with caulking rivets or set screws using holes formed in the band-shaped plate spring 6 and the wheel cover 2.

At this time, the band-shaped leaf spring 6 is not fixed to the wheel cover 2 by claws or friction, but is securely fixed by caulking studs or set screws.

Therefore, there is no fear of it falling off, and although a spring that is integrally formed with the synthetic resin housing has the disadvantage of causing wobbling as the synthetic resin ages, the device of the present invention does not cause wobbling.

Furthermore, in the device of the present invention, the band-shaped leaf spring 6 is engaged with the hump portion 1a of the wheel rim 1 at the back of the numerous tip bent portions 6a on the circumference of the wheel cover 2, which may damage the wall surface of the wheel rim and prevent rust. Since it is fixed by the numerous bent portions of the casing and does not require strong local pressure contact, the necessary fixing strength can be maintained for a long period of time.

Therefore, when attaching or detaching the wheel cover, the wheel cover can be attached or detached without requiring strong pressing force or removal force.

Therefore, the band-shaped leaf spring will not be damaged during attachment and detachment.

Furthermore, once the wheel cover 2 is fixed to the wheel rim 1, the back of the tip bent portion 6a of the band-shaped leaf spring 6 extends over the entire circumference of the wheel cover into the hump portion 1a of the wheel rim 1.
There is no risk of it falling off as it locks into place.

It should be noted that the band-shaped plate spring 6 can be manufactured from a band-shaped spring steel plate by progressive press working, so that the manufacturing cost can be reduced.

As described above, according to the device of the present invention, band-shaped leaf springs manufactured at low cost by progressive press processing are fixed to the wheel cover in an annular manner, and a large number of band-shaped leaf springs are arranged around the entire circumference of the wheel cover. *Since the bent end part is locked to the hump part of the wheel rim, there is no possibility of damaging the wheel rim or causing rust, and there is no need for strong removal force or pressing force when attaching or detaching. Moreover, it has excellent effects such as there is no fear of it falling off once it is fixed.
