DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wheel cover mounted on a disk wheel of a motor vehicle, and more particularly, to a wheel cover configured to be mounted on a rim flange edge of a disk wheel of a motor vehicle using a mounting member. .

[0002]

2. Description of the Related Art FIG. 7A is a sectional view of a general disk wheel, and FIG. 7B is a portion B (rim) of FIG. 7A.
The enlarged view of FIG. As shown in the figure, a ridge called a hump 3 is formed at a predetermined position of a rim portion 2 of the disc wheel 1 so as to protrude outward in a radial direction of the disc wheel 1, whereby the tire end moves inward. To prevent them from doing so. In the figure, the hump portion 3 is drawn large for easy understanding, but the actual hump portion is a slight bulge having a protrusion amount of about 0.5 mm.

On the other hand, as shown in FIG. 8, a wheel cover 4 attached to the disk wheel 1 of FIG. 10 generally includes a disk-shaped main body 4a and a plurality of claw portions 4b protruding from the back surface thereof. Injection molded. Then, the protrusion 4c at the tip of the claw 4b is connected to the hump 3
Of the disc wheel 1 by pressing the tip 4c of the claw portion 4b into the recess on the back side of the hump 3 by using the wire ring 5 to the outside in the radial direction of the disc wheel 1. 1

[0004]

However, there are many types of disc wheels 1 and various types even if they have the same diameter. In many cases, the position and the depth of the hump portion 3 are different for different types.
Therefore, the disc wheel 1 is
The wheel cover 4 is fixed to each type of the disc wheel 1, and has a problem that the versatility is poor.

[0005] Therefore, the technical problem to be solved by the present invention is that disc disks having the same standard diameter dimension can be used.
It is an object of the present invention to provide a highly versatile wheel cover that can be mounted regardless of its type.

[0006]

As described above, if the type of the disc wheel is different, the position of the hump is generally different even if the standard diameter is the same. Are substantially the same regardless of the model as long as the standard diameter size is the same. The present invention has been made by paying attention to this point, and has a structure in which the wheel cover is attached to the disc wheel using the rim flange portion instead of the hump portion,
It is intended to solve the above problem.

For this reason, in the present invention, as a means for attaching the wheel cover to the edge of the rim flange of the disk wheel of an automobile, a locking piece configured as follows is used. That is, the locking piece has a locking portion formed substantially along the arc-shaped outer surface of the rim flange edge of the disk wheel, and is locked to a mounting boss standing upright on the back surface of the wheel cover. The portion is slidable between a locking position where the portion contacts the outer surface of the rim flange edge of the disk wheel, and a locking release position where the locking portion separates from the outer surface of the rim flange edge, and the end portion of the mounting boss. It is mounted to be tiltable. Further, in this mounting structure, while the locking piece is held at the locking position when not tilted, the locking piece is allowed to slide to the unlocking position when tilted, and the locking piece is moved to the non-tilting position. An urging means for urging is used.

In the above construction, the position regulating means comprises a slit formed in the locking piece and a projection formed on the back surface of the wheel cover so as to penetrate the slit. In addition, an inclined surface can be provided for regulating the positions of the locking piece when the locking piece is tilted and when it is not tilted.

In the above configuration, when attaching the wheel cover to the disk wheel, first, the wheel cover is overlaid on the outer surface of the disk wheel. At this time, since the locking piece is in a non-tilted state and is at the locking position, it temporarily stops at a position where the tip of the locking portion is in contact with the rim flange edge, but when the wheel cover is pressed against the disc wheel as it is. , The locking piece tilts. Then,
The position restriction of the locking piece by the position restricting means is released, and the locking piece can slide to the locking release position. Therefore,
As the wheel cover is further pushed toward the disk wheel, the locking portion of the locking piece slides along the rim flange edge. Since the edge of the rim flange is arc-shaped, the locking piece returns to the non-tilted position when the wheel cover is pushed toward the disk wheel. Then, when the locking piece is in the non-tilted position, it engages with the rim flange edge and the state is locked.

According to the above construction, the wheel cover is attached to the rim flange edge of the disc wheel by the locking piece attached to the wheel cover, and if the disc wheel has the same standard diameter, the rim is irrespective of the type. Since the dimensional configuration of the flange edge is almost the same, it is possible to attach the wheel cover with high versatility regardless of the type, as long as the disc wheel has the same standard diameter, and the formation of a hump It can be attached to disc wheels that have not been used.

Further, when removing the wheel cover from the disc wheel, it is sufficient to insert a tool such as a screwdriver into the gap between the wheel cover and the tire, tilt the locking piece, and remove the locking piece from the rim flange edge. The wheel cover can be easily attached to and detached from the disc wheel. In order to make the removal operation easier, it is preferable that a notch for operation by a removal tool is formed in the locking portion of the locking piece.

The mounting structure having the above structure may be provided at three or more positions for mounting the wheel cover on the disk wheel. However, this structure is applied to only one of a plurality of mounting positions. In other positions, a member having a locking portion formed substantially along the outer surface of the rim flange edge of the disk wheel in the same manner as the locking portion of the locking piece is fixed to the back surface of the wheel cover. Alternatively, this may be hooked from the outer surface to the edge of the rim flange of the disk wheel and fixed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a wheel cover mounting structure according to the present invention will be described below in detail with reference to FIGS.

FIG. 1 is an exploded perspective view showing a state in which the wheel cover 10 is mounted on the disk wheel 1 of an automobile. In the figure, 1 is a disk wheel, and 6 is a tire attached to the disk wheel 1. In the present embodiment, the wheel cover 10 is attached to the disc wheel 1 by using a hook 20 and a locking hook 30, and the hook 20 is configured as a member that simply hooks on the rim flange edge 2 a of the disc wheel 1. The locking hook 30 is configured as a member for fixing to the rim flange edge 2a.

The hook 20 is formed of a thin metal plate, and is formed in a curved shape such that one end 20a is along the arc-shaped outer surface of the rim flange edge 2a of the disk wheel 1. A mounting hole 20b for mounting a boss (not shown) formed on the rear surface of the wheel cover 10 with a screw 31 (see FIG. 4) is formed substantially at the center. Although the hook 20 is not particularly detented with respect to the wheel cover 10,
When the rim is fixed to the disk wheel 1, the rim is held in a direction along the outer surface of the rim flange edge 2a.

FIG. 2 is a perspective view of a locking hook 30 used as a locking piece for fixing the wheel cover 10 to the disk wheel 1, and FIG. 3 shows a structure for regulating the position of the locking hook 30. FIG. 4 is a perspective view, and FIG. 4 is a sectional view of a main part showing a state where the wheel cover 10 is attached to the disk wheel 1. The locking hook 30 has one end 30a formed as a locking portion having a shape substantially along the arc-shaped outer surface of the rim flange edge 2a of the disk wheel 1. The mounting hole 30b to the wheel cover 10 is an elongated hole, and is slidably mounted on the boss 11 on the rear surface of the wheel cover 10 by a screw 31.

The elongated hole 30b is formed so that the locking portion 30a of the locking hook 30 is connected to the rim flange edge 2a of the disc wheel 1.
Is formed so as to be slidable between a locking position in contact with the outer surface of the rim flange and a locking release position in which the locking portion 30a is separated from the outer surface of the rim flange edge 2a. Also, screw 31
A spring 32 and a washer 33 are mounted between the locking hook 30 and the locking hook 30, so that the locking hook 30 can be tilted with respect to the end face of the mounting boss 11, and the locking hook 30 is normally in a non-tilted position. It is configured as follows.

On the other hand, while the locking hook 30 is held at the locking position when not tilted, it can slide to the unlocking position when tilted. 30c (slit) is formed,
On the back surface of the wheel cover 10, a projecting piece 12 that engages with the opening 30c is formed. The protruding piece 12 has an inclined surface 12a at the distal end on the radially inner surface side of the wheel cover 10, and the base end of the inclined surface 12a is a horizontal surface 12b having the same height as the boss 11, and the locking hook 30 is provided with the inclined surface 12b. It constitutes a stopper to keep it parallel.

FIG. 5 shows a modification. This example is an example in which a narrow locking hook 34 is attached to the wheel cover 10 with one screw 31. in this case,
The opening 34c is formed to have such a small width that only one protruding piece 12 can be inserted, as shown in (b), and the mounting hole 34b is formed only at one location.

FIG. 6 is a process diagram showing a procedure for attaching the wheel cover 10 to the disk wheel 1. First,
After attaching the hooks 20 and 30 to the wheel cover 10, the hooks 20 are hooked on the outer surface of the rim flange edge 2 a of the disc wheel 1, and the wheel cover 10 is overlapped on the outer surface of the disc wheel 1. At this time, since the locking hook 30 is not tilted with respect to the wheel cover 10, it comes into contact with the rim flange edge as shown in FIG.

When the wheel cover 10 is pressed against the disc wheel 1 as it is, the locking hook 30 tilts.
(FIG. 6 (b)). Then, the inclined surface 12a of the protruding piece 12
When the positional relationship of the end face 30d of the slit 30c with respect to the position changes, the position restriction of the locking hook 30 to the locking position is released, and the locking hook 30 can slide to the locking release position side.
Accordingly, the locking portion 30a of the locking hook 30 slides along the rim flange edge 2a as the wheel cover 10 is further pushed into the disk wheel 1 side (FIG. 6C). Further, since the rim flange edge 2a has an arc shape, the locking piece 30 returns to the non-tilt position when the wheel cover 10 is pushed toward the disk wheel 1. When the locking hook 30 is at the non-tilt position, it engages with the rim flange edge 2a and the state is locked (FIG. 6D).

According to the above construction, the wheel cover 10 is fixed to the rim flange edge 2 of the disc wheel 1 by the locking pieces (locking hooks) 30 attached to the wheel cover 10.
a, and if the disc wheel 1 has the same standard diameter, the dimensions of the rim flange edge 2a are almost the same regardless of the type. Regardless of the type, the wheel cover 10 can be mounted with high versatility, and can be mounted on the disc wheel 1 on which no hump is formed.

When the wheel cover 10 is to be removed from the disc wheel 1, a tool 40 (see FIG. 4) such as a screwdriver is inserted through a gap between the wheel cover 10 and the tire 6, and the locking hook 30 is moved from the rim flange edge 2a. Since it is sufficient to remove the wheel cover 10, the wheel cover 10 can be easily removed as well as attached to the disk wheel 1. In order to make this removal operation easier, the locking portion 30a of the locking hook 30 is used.
In addition, for example, as shown by a virtual line in FIG. 2, it is preferable to form a notch 30e for removal operation using a removal tool such as a screwdriver.

In the above configuration, two types of hooks (the hook 20 and the locking hook 30) are used, but all of them may be the locking hook 30. The number of attachment locations may be appropriately determined as long as the number is three or more, and the engagement hook 30 serving as the engagement means of the present invention may be used at any one or more locations.

In addition, since the hooks 20 and 30 are used for attachment, the claws (4b and 4c in FIG. 8) formed on the conventional wheel cover become unnecessary, and the boss 11 without undercut is not required. In addition, since it is only necessary to form the protruding piece 12, the molding die for the wheel cover can be made to have a simple structure without using a slide. Therefore, cost reduction becomes possible.
