The invention relates to wheel rims and more particularly to a detachable rim for a vehicle wheel.
A vehicle tire is mounted on a rim which is an important component of an automobile. A conventional wheel rim includes a hub rotatably mounted on an axle, a plurality of spokes radially extending from the hub, and a rim member. The wheel rim has characteristics of being structurally strong, reliable in use and lightweight. Also, it addresses issues including being quick in assembly or disassembly.
For the conventional wheel rim, the rim member is secured to a tire and the tire is kept airtight. However, it is required that a mechanic, rather than an ordinary individual, uses a tool and/or a device to mount a tire on the wheel rim or detach the tire therefrom. In detail, in a tire replacement operation, a mechanic must deflate the tire, insert an elongated, flat rod into a joining portion of the tire and the rim member, exert force to slightly separate the tire and the rim member, and finally use a tire removal device to detach the tire from the rim member.
However, the above operation is both labor intensive and time consuming. Further, it can be done only by a mechanic rather than an ordinary individual.
Thus, the need for improvement still exists.
It is therefore one object of the invention to provide a wheel rim in which only a tool (e.g., screwdriver) is required for the assembly of a tire or the detachment of the tire therefrom. Further, an individual, rather than a mechanic, can do it in an easy way.
It is another object of the invention to provide a wheel rim capable of quickly, easily mounting a tire thereon and keeping the tire in airtight thereafter.
For achieving above an other objects of the invention, there is provided a rim of a vehicle wheel, comprising a rim body including a central member and a peripheral well with a tire secured thereon wherein the central member includes an outboard tire bead seat is formed between an outer annular flange of the peripheral well and an inner annular ridge thereof, an inboard tire bead seat is formed between an inner annular flange of the peripheral well and an outer annular ridge of the peripheral well, an outboard tire bead of the tire is mounted on the outboard tire bead seat, an inboard tire bead of the tire is mounted on the inboard tire bead seat, and a diameter of the outer annular flange is less than that of the inn annular flange so that the tire is configured to replace with a new one by removing through a peripheral opening; and a ring releasably secured to a peripheral edge of the rim body to close the peripheral opening.
Preferably, the peripheral edge extends from an outer surface of the outer annular flange to an outer surface of the cavity, and wherein the peripheral edge is shaped complementarily to the ring so that the ring is configured to secure thereto.
Preferably, wherein the ring includes a plurality of holes equally spaced apart, the central member further comprises a plurality of equally spaced apart cavities on an annular edge, each cavity is formed with one of a plurality of threaded holes, and a plurality threaded fasteners are configured to drive through the holes into the threaded holes respectively, thereby securing the ring the peripheral edge of the rim body.
Preferably, the ring is shaped complementarily to the inner annular flange.
Preferably, the central member further comprises a hub and at least one spoke radially extending from the hub to an annular edge of the peripheral well.
The invention, as well as its many advantages, may be further understood by the following detailed description and drawings in which:
Referring to
The rim body 10 includes a central member 11 and a peripheral well 12 with tire 50 secured thereon. The central member 11 includes a hub 13 with an axle (not shown) of a vehicle fastened therein, and a plurality of spokes 14 radially extending from the hub 13 to an annular edge of the peripheral well 12.
The ring 30 includes a plurality of holes 31 equally spaced apart. A plurality of equally spaced apart cavities 15 are formed on an annular edge of the central member 11. A plurality of threaded holes 16 each are formed on the cavity 15. A plurality of screws 40 are driven through the holes 31 into the threaded holes 16 respectively. As a result, the ring 30 is secured to a peripheral edge 17 of the rim body 10.

In a tire 50 mounting operation, the individual may perform reverse operations. In detail, the tire 50 is mounted on the rim body 10 by passing through the opening 24. Next, air is inflated into the tire 50 to urge both the outboard tire bead 51 of the tire 50 against the outboard tire bead seat 20 and the inboard tire bead 52 of the tire 50 against the inboard tire bead seat 23 respectively. As an end, the tire 50 is mounted. It is envisaged by the invention that only a tool (e.g., screwdriver) is required for the assembly or detachment of the tire 50. Further, an individual, rather than a mechanic, can do it in an easy way.
As shown in
Many changes and modifications in the above described embodiment of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claims.
