Abstract

PURPOSE:To prevent the looseness of a bolt due to vibration during vehicle running by engagingly locking an ornament onto the inside of a locking projection formed on a disk part in such a manner as to be attachable and removable, passing a fixing bolt through the skirt part of the ornament in the state spirally fitted in the axle direction, and bringing its top end surface into contact with the disk part. CONSTITUTION:An ornament 3 covers the axle end of an axle hole, and locking parts 32... are intermittently protruded on the skirt part 31 of the ornament 3. The locking parts 32 are engagingly locked to the inside of locking projections 121 of a spoke part 12. To mount the ornament 3 onto a wheel W, the ornament 3 is fitted to the enlarged diameter part 21 of the axle hole 2 in the state where the locking parts 32... of the ornament 3 are situated between the locking projections 121... of the disk part 1. The locking parts 32 of the ornament 3 are situated on the inside of the locking projections 121 of the spoke part, and a fixing bolt 4 is fastened to press the top end of the bolt 4 onto a hub 11, whereby the frictional resistance of the screw part is enlarged, so that the fixing bolt 4 is difficult to loosen.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ornament mounting structure for a vehicle wheel.

0002

2. Description of the Related Art In a conventional mounting structure of this type, the ornament was bolted to the disc portion of the wheel (Utility Model Application No. 8331/1983).

0003

[Problems to be Solved by the Invention] However, in such a conventional structure, the bolt is simply passed through the flange portion of the ornament and then screwed into the disk portion. This bolt tends to loosen due to vibrations while the vehicle is running, resulting in the inconvenience that it takes time and effort to manage the attachment of the ornament.

[0004] An object of the present invention is to eliminate such inconveniences.

[0005]

[Means for Solving the Problems] In order to achieve the above object, in the ornament mounting structure for a vehicle wheel according to the present invention, an ornament is installed on the surface side of a disc part, and the ornament is formed on the disc part by the ornament. In the ornament mounting structure for a vehicle wheel that covers a fixed axle hole, a required number of locking protrusions are formed on the disk portion, and the ornament is removably latched inside the locking protrusions, and the ornament A fixing bolt is threaded through the hem of the disc along the axle direction, and the distal end surface of the fixed bolt is brought into contact with the disc part.

[0006] The locking protrusion may also be formed on a spoke portion of the disk portion.

[0007]Furthermore, a hem portion may be provided protruding from the peripheral edge of the ornament, and this hem portion may be fitted into the axle hole without a gap.

[0008]

[Operation] Since the ornament mounting structure for a vehicle wheel according to the present invention is constructed as described above, when the fixing bolt is tightened, the ornament is locked to the locking protrusion of the disk portion and is attached to the disk portion. Since the distance is to be widened, the friction in the rotational direction between the male threaded portion of the fixing bolt and the female threaded portion of the ornament into which the fixing bolt is screwed increases.

[0009] Since the spoke portions of the disk portion protrude toward the surface side, if the locking protrusions are formed on these spoke portions, the locking protrusions can be easily formed.

[0010] Furthermore, if a hem portion is provided protruding from the peripheral edge of the ornament and this hem portion is fitted into the axle hole without a gap, it is difficult for water, dirt, etc. to enter the axle hole.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, W is a vehicle wheel, 1 is a disk portion of this wheel W, and R is a rim portion integrally formed with the disk portion 1. Note that the disk part 1 is the hub part 1.
1 and spoke portions 12 extending radially from the hub portion 11.
, 12,...

Next, in FIG. 2, 2 is an axle hole;
It is formed at the center of the hub portion 11. This axle hole 2
The vehicle axle passes through it. Reference numeral 21 denotes an enlarged diameter portion of the axle hole 2, which is formed on the surface side of the hub portion 11. This enlarged diameter portion 21 is for fitting the peripheral portion of the ornament 3 described later. Note that 121, 121, . . . are locking protrusions, which are formed at appropriate intervals on the edges of the spoke portions 12, 12, . The inner diameter of this locking protrusion 121 is larger than the inner diameter of the enlarged diameter portion 21. The functions of the locking protrusions 121, 121, . . . will be described later. Reference numeral 3 designates a crown-shaped ornament, which is fitted into the enlarged diameter portion 21 of the hub portion 11 . This ornament 3 covers the end of the axle passing through the axle hole 2. Reference numerals 32, 32, . . . are hook portions, which are intermittently protruded from the hem portion 31 of the ornament 3. This latching portion 32 is latched to the inside of the latching protrusion 121 of the spoke portion 12 . Reference numeral 33 denotes a bolt hole, which is formed in the skirt portion (of the ornament 3) 31 along the axle direction. The fixing bolt 4 is screwed into this bolt hole 33. The fixing bolt 4 is threaded into the bolt hole 33, passes through the skirt portion 31, and comes into contact with the hub portion 11. Therefore, when the fixing bolt 4 is tightened, the ornament 3 can be attached to the locking protrusions 121 of the spoke parts 12, 12, .
121, . . ., the distance from the hub portion 11 increases, so the friction in the rotational direction between the male threaded portion of the fixing bolt 4 and the female threaded portion of the bolt hole 33 increases. Therefore, the fixing bolt 4 is difficult to loosen. The fixing bolts 4 can be determined as appropriate depending on the design of the disk portion 1 and the number or shape of the spokes. For example, it may be one. Also, 11
1 is a locking recess, which is formed in the hub portion 11. The tip of the fixing bolt 4 enters this locking recess 111 to position the fixing bolt 4 relative to the hub portion 11.

In this ornament mounting structure, in order to attach the ornament 3 to the wheel W, first, the locking portions 32, 32, . . . of the ornament 3 are positioned between the locking protrusions 121, 121, . In this state, the ornament 3 is fitted into the enlarged diameter portion 21 of the axle hole 2. Then, rotate ornament 3 appropriately (around the axis).
, the locking portions 32, 32, . . . are the locking protrusions 12 of the disk portion 1.
This rotation is stopped when it is located inside 1, 121, . Then, the ornament 3 is fixed to the wheel W by tightening the fixing bolt 4 and bringing the tip of the fixing bolt 4 into pressure contact with the hub portion 11.

[0014]

[Effects of the Invention] The ornament mounting structure for a vehicle wheel according to the present invention is such that an ornament is installed on the surface side of a disc portion, and the ornament covers an axle hole formed in the disc portion. A required number of locking protrusions are formed on the disk portion, the ornament is removably latched on the inside of the locking protrusions, and a fixing bolt is screwed along the axle direction on the hem of the ornament. The end surface of the fixing bolt that passed through was brought into contact with the disc part, so when the fixing bolt is tightened, the ornament is locked with the locking protrusion of the disc part and is connected to the disc part. Since the distance is to be widened, the friction in the rotational direction between the male threaded portion of the fixing bolt and the female threaded portion of the ornament into which the fixing bolt is screwed increases.

[0015] Therefore, if this ornament mounting structure is used, the fixing bolts are unlikely to loosen even if vibrations occur while the vehicle is running, and as a result, the ornament mounting can be easily managed.

[0016] Since the spoke portions of the disk portion protrude toward the surface side, if the locking protrusions are formed on these spoke portions, the locking protrusions can be easily formed.

[0017] Furthermore, if a hem portion is provided protruding from the peripheral edge of the ornament, and this hem portion is fitted into the axle hole without a gap, it is difficult for water, dirt, etc. to enter the axle hole.
