DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings and initially to FIGS. 1-4, a wheel rim assembly in accordance with the preferred embodiment of the present invention comprises a wheel rim 4, a locking ring 1, a wheel rim cover 2, and a central cap 3.

The wheel rim 4 has a rim body 41 and a central hole 42. The wheel rim 4 has an inner flange 43 formed in the central hole 42.

The locking ring 1 includes a ring body 11. The ring body 11 has an outside formed with an enlarged portion 12 protruding outward. The ring body 11 has an inside provided with a groove 13 corresponding to the enlarged portion 12. The ring body 11 has an end formed with multiple positioning pieces 14 protruding outward. The positioning pieces 14 are arranged evenly and annularly. A predetermined interval is defined between the positioning pieces 14. Each of the positioning pieces 14 has a predetermined radian. Each of the positioning pieces 14 has an outside formed with a locking edge 15 protruding outward. Each of the positioning pieces 14 has an inside provided with a positioning slot 16 corresponding to the locking edge 15. The positioning slot 16 has two ends extending to two sides of each of the positioning pieces 14 respectively. The locking ring 1 further includes a C-shaped first elastic circle (or loop) 17. The first elastic circle 17 is mounted in the positioning slot 16. The locking ring 1 is mounted in the central hole 42 of the wheel rim 4, and the locking edge 15 is locked on the inner flange 43 of the wheel rim 4.

The wheel rim cover 2 includes a wheel rim cover body 21. The wheel rim cover body 21 has a center provided with a through hole 22 penetrating the wheel rim cover body 21. The through hole 22 has an inside formed with a protruding annular wall 23. The wheel rim cover body 21 has an inner side face formed with multiple locking blocks 24. The locking blocks 24 are used to lock the rim body 41 of the wheel rim 4, and the annular wall 23 corresponds to the ring body 11.

The central cap 3 includes a central cap body 31. The central cap body 31 has an end formed with multiple fixing (or securing) plates 32 protruding outward. The fixing plates 32 are arranged evenly and annularly. A predetermined interval is defined between the fixing plates 32. Each of the fixing plates 32 has a predetermined radian. Each of the fixing plates 32 has an outside formed with a protruding edge 33. Each of the fixing plates 32 has an inside formed with a retaining groove 34 corresponding to the protruding edge 33. The central cap 3 further includes a C-shaped second elastic circle (or loop) 35 mounted in the retaining groove 34. The central cap 3 extends through the through hole 22 of the wheel rim cover 2 and is fitted into the ring body 11 of the locking ring 1, so that the protruding edge 33 is locked in the groove 13, and the central cap body 31 presses the annular wall 23.

In practice, each of the positioning pieces 14 and the first elastic circle 17 have the same radian, so that the first elastic circle 17 is fitted into the positioning slot 16 closely.

In assembly, the locking ring 1 is pressed into the central hole 42 of the wheel rim 4, so that the locking edge 15 passes and is locked on the inner flange 43 of the wheel rim 4. Then, the locking blocks 24 of the wheel rim cover 2 are mounted on and secured to the rim body 41 of the wheel rim 4. Then, the central cap 3 extends through the through hole 22 of the wheel rim cover 2 and is pressed into the ring body 11 of the locking ring 1, so that the protruding edge 33 is locked in the groove 13 of the ring body 11, and the central cap body 31 presses the annular wall 23.

Accordingly, the central cap 3 is locked onto the locking ring 1 to press the wheel rim cover 2 after the locking ring 1 is locked onto the wheel rim 4, so that the wheel rim cover 2 is fixed securely, thereby preventing the wheel rim cover 2 from being detached from the wheel rim 4.

Referring to FIGS. 5-8, the two ends of the positioning slot 16 of the locking ring 1 do not extend to two sides of each of the positioning pieces 14. In addition, the positioning slot 16 of the locking ring 1 is a perforation and penetrates the locking edge 15. The first elastic circle 17 is formed with multiple insertion portions 171 by bending. Each of the insertion portions 171 is inserted into the positioning slot 16 of one of the positioning pieces 14, so that the first elastic circle 17 is positioned in place. In another preferred embodiment of the present invention, the ring body 11 of the locking ring 1 and the annular wall 23 of the wheel rim cover 2 are formed integrally as shown in FIG. 8.

Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the scope of the invention.
