Description
BACKGROUND OF THE INVENTION
1. Technical Field
The present invention relates to a wheel cover in which a fixing mechanism of fixing the wheel cover to a disk wheel of an automobile is formed integrally with a wheel cover body.
2. Related Art
Generally, a related structure shown in
FIG. 6
is known for mounting a wheel cover onto a disk wheel of an automobile. In more detail, the wheel cover
1
is made of synthetic resin. Engagement claws
3
(in the figure, only one claw is shown) formed integrally with a cover body
2
of the wheel cover
1
are disposed at plural positions in the circumferential direction at the outer periphery of the back side of the cover body
2
. Metallic wire rings
4
are disposed at the radially inner side of the engagement claws
3
in order to prevent the engagement claws
3
from being deformed inwardly in the radial direction. An engagement convex part
3
a
of the engagement claw
3
is engaged with a concave part
6
a
of a rim
6
of the disk wheel
5
.
However, the related structure is at a disadvantage in that, since the structure is composed of the synthetic resinous wheel cover
1
and the metallic wire rings
4
, and they need to be sorted out from each other when recycled, the related structure is inferior in recyclability, and, since the metallic wire ring
4
is a necessary component, weight saving is difficult.
SUMMARY OF THE INVENTION
The present invention has been made in consideration of the foregoing, and an object of the present invention is to provide a wheel cover capable of improving recyclability and, in addition, realizing weight saving.
In order to achieve the object, the wheel cover comprising:
a cover body made of synthetic resin disposed on a disk wheel of an vehicle to cover a side face of the disk wheel;
a plurality of elastic deformable fixing pieces formed integrally with the cover body engaged with a rim of the disk wheel;
a plurality of engagement portions provided with the plurality of fixing pieces, respectively; and
a plurality of engagement parts formed integrally with the cover body for keeping the plurality of fixing pieces bent by engagement with the plurality of engagement portions.
In the above construction, preferably, the engagement portion forms an engagement hole, the engagement part forms an engagement member to be inserted into the engagement hole. A large diameter part having a diameter larger than a diameter of the engagement hole is formed at an end of the engagement member. The engagement portion is formed at an intermediate part of the fixing piece. An intermediate part of the fixing piece is formed thinner than the other part of the fixing piece. The plurality of fixing pieces and the plurality of engagement parts are formed on a face of the cover body opposed to the side face of the disk wheel.
In the above-mentioned structure, when the wheel cover is mounted onto the disk wheel, each front end of the fixing pieces is first engaged with the rim of the disk wheel in such a way as to allow the cover body to cover the side face of the disk wheel. Thereafter, the cover body is pressed against the disk wheel, so that each engagement part of the cover body is engaged with the corresponding engagement portion of the fixing piece. This engagement enables the fixing piece to be kept bent. At this time, the front end of each fixing piece presses against the rim because of the elastic force of the fixing piece. The pressing force allows the disk wheel to hold the wheel cover. In this case, since each fixing piece is kept bent because of the engagement with the engagement part, the wheel cover can maintain the state of being fixed to the disk wheel without using other members such as wire rings.
Additionally, since each fixing piece and each engagement part that are the fixing mechanism of the wheel cover are formed integrally with the cover body made of synthetic resin, and all of the wheel cover is made of synthetic resin, recyclability can be improved. Additionally, since other members, such as wire rings, are not needed, weight saving can be realized.

has first and second curved concave parts
15
,
16
and a curved convex part
17
along the whole periphery thereof. The first and second curved concave parts
15
,
16
are formed so that the side of an inner surface
14
b
opposite to the side of an outer surface
14
a
onto which the tire
13
is mounted is concave. The curved convex part
17
is located between the first and second curved concave parts
15
,
16
and whose inner surface
14
b
is convex.
As shown in
FIG. 3
, the wheel cover
20
is made of synthetic resin and comprise: a cover body
21
shaped like a disk; a plurality of fixing pieces
22
(six fixing pieces in this example) spaced out evenly in the circumferential direction at the outer periphery of the back side
21
a
of the cover body
21
; and six engagement members
23
that are engagement parts disposed on the back side
21
a
of the cover body
21
in correspondence with the respective fixing pieces
22
. The cover body
21
, the fixing pieces
22
, and the engagement, members
23
are formed by integral molding.
The cover body
21
is shaped like a disk slightly larger than the outline of the front end of the rim
14
, and has a sufficient size to cover the side face of the disk wheel
11
. The cover body
21
has a plurality of openings
24
. A so-called self-hinge
25
is formed at the base of each fixing piece
22
as shown in
FIGS. 4 and 5
. Each fixing piece
22
is bent so that the front end
22
a
of the fixing piece
22
is directed outwardly in the radial direction with the self hinge
25
as a fulcrum. The front end
22
a
of the fixing piece
22
is curved so as to fit the second curved concave part
16
of the end side of the rim
14
thereto. In the fixing piece
22
, an intermediate part
22
b
in the extending direction is formed to be slightly thinner than the other part of the fixing piece
22
so as to easily bend. The intermediate part
22
b
has a circular engagement hole
26
that is the part to be engaged.
The engagement member
23
is designed to be disposed at a position corresponding to the engagement hole
26
and be engaged with the engagement hole
26
when the corresponding fixing piece
22
is bent as shown in FIG.
1
and
FIG. 5. A
large diameter part
23
a
for preventing the member
23
from sliding out of the engagement hole
26
is formed at the tip of the engagement convex part
23
.
In the above-mentioned structure, the wheel cover
20
is mounted onto the disk wheel
11
as follows.
First, the wheel cover
20
is placed on the disk wheel
11
whose side face is directed upward. At this time, the front end
22
a
of each fixing piece
22
of the wheel cover
20
is brought into contact with the second curved concave part
16
of the rim
14
and is engaged therewith (see FIG.
5
). Thereafter, after confirming that the front ends
22
a
of all the fixing pieces
22
are evenly engaged with the second curved concave parts
16
of the rim
14
, the cover body
21
is pressed against the disk wheel
11
(see arrow A of FIG.
5
). As a result, the front end
22
a
of the fixing piece
22
is pressed against the inner surface of the second curved concave part
16
of the rim
14
(see arrow B of FIG.
1
), and, accordingly, the intermediate part
22
b
of the fixing piece
22
is elastically bent so as to protect toward the cover body
21
, and the engagement member
23
is inserted into the engagement hole
26
and is engaged therewith (see FIG.
1
). This engagement allows the fixing piece
22
to maintain the state of being curved.
At this time, the front end
22
a
of the fixing piece
22
is in a state of pressing against the inner surface
14
a
of the rim
14
because of the elastic force of each fixing piece
22
, and the wheel cover
20
is held by the disk wheel
11
because of this pressing force of each fixing piece
22
. In this case, since each fixing piece
22
can maintain the state of being curved by the engagement between the engagement member convex part
23
and the engagement hole
26
, the wheel cover
20
can maintain the state of being fixed to the disk wheel
11
without using other members such as wire rings.
Since the fixing piece
22
and the engagement member convex part
23
that are the fixing means of the wheel cover
20
are formed integrally with the cover body
21
made of synthetic resin, respectively, and all the wheel cover
20
is made of synthetic resin, recyclability can be improved. Additionally, since other members, such as wire rings, are not needed, and weight saving can be achieved.
As described above, according to the present invention, since each fixing piece serving as a fixing means of the wheel cover presses against the rim while being curved, and maintains the curved state by the engagement with the engagement convex part, the wheel cover can maintain the state of being fixed to the disk wheel without using other members such as wire rings. Additionally, since the fixing piece and the engagement part each serving as a fixing means of the wheel cover are formed integrally with the cover body made of synthetic resin, and all the wheel cover is made of synthetic resin, recyclability can be improved. Additionally, since other members, such as wire rings, are not needed, weight saving can be achieved.
