[Industrial applications]

 The present invention relates to a vehicle wheel having an outer surface with a design having an uneven pattern, and more particularly, to a configuration of a center cap and a portion in the vicinity thereof.

[0002]

[Prior art and its problems and problems]

 Most of the recent aluminum wheels, etc., have a center cap type appearance. Normally, an aluminum wheel has a structure in which the disc portion is screwed to the hub at multiple points by hub bolts, and the axle end projects from the central portion surrounded by the screw fastening portion. Therefore, a center cap that covers the axle protruding portion and a half cap that covers the screw fastening portion are attached to the center of the disk portion of the wheel.

As a wheel structure of this type, there is one already disclosed in Japanese Utility Model Laid-Open No. 61-87102, in which, as shown in FIG. 3, a plurality of mounting holes (8) for mounting hub bolts are provided. On the inner circumference of the annular recess (7) forming the (8), the cylindrical wall portion (4) protrudes to the wheel outer surface side and the disk portion (2) is fitted in the annular recess (7) and at the center. An annular half cap (1) having a fitting hole (5) and a tubular part (19) fitted into the fitting hole (5) of the half cap (1) are provided and extended from this tubular part. And a center cap (10) having engaging legs.

In this case, the half cap (1) is housed in the annular recess (7) of the disc portion (2), and the tubular portion (19) of the center cap (10) is attached to the half cap (1). When the engaging leg portion which is inserted into the fitting hole (5) and is continuously provided at the tip of the fitting hole portion (5) is engaged with the engaged convex portion (15) formed on the cylindrical wall portion (4), the center cap (10 ) Is attached in a retaining state, and the half cap (1) is pressed and fixed in a retaining state by a protruding step portion formed on the outer periphery of the cylindrical portion of the center cap (10). As a result, the center cap (10) projects from the center of the wheel, and the hub bolt mounting portion on the outer periphery of the center cap (10) is covered with the half cap (1).

However, in order to make the outer peripheral surface of the center cap (10) have an uneven pattern, it is difficult to secure the continuity of the uneven pattern because the area where the uneven pattern is formed is narrow. The half cap (1) is attached and fixed to the central part of the disc part (2) by the center cap (10), but the uneven pattern on the surface of the half cap (1) is completely different from that on the surface of the disc part (2). In addition, the surface of the half cap (1) is conical, and the surface of the disk portion (2) is discontinuous.

Further, since the half cap (1) has a thin plate shape, in the case of a wheel in which the outer surface of the disc portion (2) of the outer peripheral portion is provided with an uneven pattern, this half cap (1 The problem that 1) and design continuity cannot be ensured occurs. According to the present invention, "an annular half cap (1) for covering an annular recess (7) of a disk portion (2) having a plurality of mounting holes (8) (8) for fixing hub bolts, and A center cap made of synthetic resin, which is arranged so as to press the central part of the half cap (1) and engages with a cylindrical wall part (4) serving as an inner peripheral wall of the annular recess (7) in a retaining state. (10) and (10) and (2) are provided in the center of the disc part (2), so that the outer appearance of the wheel surface in the outer peripheral area of the center cap (10) is designed to be continuous over a wide range in a design manner. That is the subject.

[0007]

[Technical means]

 The technical means of the present invention taken to solve the above-mentioned problem is that "the outer surface of the disk portion (2) has an uneven pattern portion (17) in the outer peripheral area of a certain range from the outer peripheral edge of the annular recess (7). The outer peripheral wall of the annular recess (7) has a taper surface (9) at the end on the disk surface side, and the half cap (1) has a surface with the uneven pattern (17). That is, a continuous concavo-convex pattern portion (18) is formed, and at the outer peripheral edge of the other back surface, a tapered surface (6) that is in contact with at least the outer peripheral edge of the tapered surface (9) is formed ”.

[0008]

[Action]

 On the outer surface of the half cap (1), an uneven pattern portion (18) similar to the uneven pattern portion (17) formed on the outer surface of the disk portion (2) is formed. The outer peripheral edge of the half cap (1) and the peripheral wall edge of the annular recess (7) are in contact with each other by the tapered surfaces. Therefore, compared with the case where the peripheral edge is fitted in the part that is recessed at a right angle to the flat surface, the peripheral edge of the half cap (1) and the outer peripheral area of the annular recess (7) on the outer surface of the disk portion (2). And the unevenness pattern part (17) formed on the outer surface of the disc part (2) and the unevenness pattern part (18) on the outer surface of the half cap (1) are secured. Becomes In other words, the boundary portion of the uneven pattern is hard to see, and the outer appearance of the uneven pattern is uniform and continuous from the outer periphery of the main cylinder part (12) of the center cap (10).

Further, the concavo-convex pattern part is continuously formed in a wide range from the surface of the half cap (1) on the outer periphery of the center cap (10) to the surface of the disk part (2).

[0010]

【effect】

 On the outer periphery of the center cap (10), the surface of the half cap (1) and the uneven pattern part of the disk part (2) are evenly continuous, so the disk part (2) with continuous uneven pattern is formed. An external appearance can be realized in which only the center cap (10) projects at the center of the outer surface of the. Further, in this case, the boundary between the uneven pattern part (17) of the disk part (2) and the uneven pattern part (17) of the half cap (1) is difficult to see, and the continuity of the uneven pattern is sufficient. ..

Further, it is possible to obtain an appearance in which a concavo-convex pattern is formed over most of the outer peripheral region of the center cap (10).

[0012]

【Example】

 In the embodiment shown in FIG. 1 and FIG. 2, the disc portion (2) is formed with a hub hole (3) through which an axle is inserted in the center thereof, and an annular recess (7) is formed on the outer periphery of the hub hole (3). ) Are formed concentrically. The inner circumference of the annular recess (7) forms the cylinder wall (4), and in this embodiment, the tip of the cylinder wall (4) slightly projects from the outer surface of the disc (2). There is. A plurality of mounting holes (8) and (8) are formed in the bottom wall of the annular recess (7), and a hub bolt is inserted into this, and when a nut is tightened into this, the hub and the disk part (2) are fixed. To be done. The edge of the outer peripheral wall of the annular recess (7) is a tapered surface (9) that expands outward. Further, an uneven pattern portion (17) is continuously formed from the peripheral edge of the annular recess (7) on the outer surface of the disk portion (2).

The half cap (1) is an annular body made of synthetic resin, and has a fitting hole (5) formed at the center thereof to be fitted on the cylindrical wall portion (4). The outer peripheral area of 5) is an annular step (20) which is recessed from the outer surface of the entire half cap (1). The peripheral edge of the back surface of the half cap (1) is a taper surface (6) which matches the taper surface (9) in this embodiment. Further, on the entire outer surface of the half cap (1), a concavo-convex pattern portion (18) is formed over the entire outer peripheral region of the annular step portion (20), and the concavo-convex pattern is formed on the tapered surface (6) and the tapered surface (6). When it is fitted into the annular recess (7) in a predetermined posture so that it coincides with (9), it continues in series with the uneven pattern portion (17) on the outer periphery. In this embodiment, concave portions are continuously formed between mesh-shaped convex portions, and the mesh is continuous between the outer surface of the disk portion (2) and the outer surface of the half cap (1) without any break or deviation. Will be done.

Since the peripheral edge of the half cap (1) and the peripheral edge of the annular recess (7) are taper fitted, the diameter of the fitting hole (5) is smaller than the outer diameter of the cylindrical wall portion (4). Even if it is set to a large size, it will be installed in a state where the peripheral edges of both are exactly aligned. The center cap (10) has a thick main cylinder part (12) protruding from the outer peripheral edge of the top plate part (11) to the rear surface side, and a concentric mounting leg cylinder part (13) on the inner peripheral side. ) Is projected, and the height of the mounting leg cylinder portion (13) is set higher than that of the main cylinder portion (12). The main cylindrical portion (12) has a circular tip portion, and the cross-sectional outer diameter from the circular portion to the peripheral edge of the top plate portion (11) is set to a hexagonal shape, and the overall height is compared. The overall appearance is like a large nut because it is set to a low level. The inner peripheral diameter of the main cylindrical portion (12) is set to be substantially equal to or slightly larger than the outer peripheral diameter of the cylindrical wall portion (4) of the disc portion (2).

Further, a locking claw (14) is projected on the outer peripheral surface of the distal end of the mounting leg tube portion (13), and an inclined piece whose cross-sectional shape of the locking claw (14) is inclined toward the distal end is provided. It has a substantially triangular shape and is engaged with and disengaged from the engaging projection (15) having an inclined surface formed on the inner peripheral surface of the cylindrical wall portion (4) and inclined toward the distal end side of the cylindrical wall portion (4). It is possible to engage in the axial direction. In the case of the wheel configured as described above, the half cap (1) is mounted in the annular recess (7) in such a manner that the fitting hole (5) is fitted onto the cylindrical wall portion (4). At this time, the mounting position of the half cap (1) is determined so that the concavo-convex pattern part (17) of the disc part (2) and the concavo-convex pattern part (18) of the outer surface of the half cap (1) are connected. Then, the peripheral edge of the half cap (1) is taper-fitted to the peripheral edge of the annular recess (7), so that the disc portion (2) and the half cap (1) are concentric with each other and closely adhere to each other. Thus, there is almost no gap at the boundary between the uneven pattern portion (17) and the uneven pattern portion (18).

Next, when the mounting leg cylinder part (13) of the center cap (10) is inserted into the cylinder wall part (4), the position of the locking claw (14) is determined in relation to the engagement protrusion (15). Since these are engaged, the center cap (10) engages with the cylindrical wall portion (4) in a retaining state. At this time, the tip of the main cylinder part (12) is just fitted into the annular step part (20) formed following the fitting hole (5) of the half cap (1), and the main wall part (4) is It will be interposed between them.

The half cap (1) is also fixed to the disc part (2) until the peripheral edge of the annular recess (7) and the peripheral edge of the half cap (1) are maintained in the above state. In addition, when the center cap (10) is forcibly pulled out from the cylindrical wall portion (4) at the time of removal, the disk portion (2) comes off. When the wheel is in use, no external force acts in the pull-out direction on this half cap (1), so there is no risk of the center cap (10) coming off during use.
