1. Field of the Invention
The present invention relates to a tire protection device and, more particularly, to an annulus tire protection device integrated with a tire externally to avoid the tire from wear out of direct friction with pavements and to optimize aesthetics of the tire.
2. Description of the Related Art
The treads of general tires installed on a running car directly rub on pavements and are fast worn, so that old tires are routinely replaced and become lots of abandoned tires which enormously affect the environment and increase expenses of drivers. On the other hand, visual effects of general tires with black appearance are also weakened.
Therefore, an objective of the present invention is to provide a tire protection device to improve the aforementioned shortcoming and deficiency of the prior art. The tire protection device of the present invention is adapted for covering a tire's external tread to minimize direct friction-induced wear between the tread of the tire and pavements, frequent replacement of tires, and any abandoned environmental-unfriendly tires. Furthermore, the tire protection device of the present invention is capable of optimizing and diversifying an appearance and colors of the tire.
To achieve the foregoing objective, a tire protection device of the present invention includes an annular wall and two centripetal lip portions extending inwards from two side ends of the annular wall in a radial direction respectively. The annular wall includes an accommodating space internally for receiving a tier. The annular wall further includes internal and external surfaces spaced in the radial direction. Concave and convex patterns are formed on the internal surface of the annular wall to match tread patterns on a tread of the tire. The tread of the tire is wrapped by the annular wall with the lip portions compactly covering two sidewalls of the tire when the tire is received in the accommodating space.
In a preferred form, an inner diameter of the annular wall is slightly greater than or equal to an outer diameter of the tire, and a spacing between the two lip portions is not less than a width of the tire. Patterns and textures are formed on the external surface of the annular wall and the lip portions respectively.
In a preferred form, each of the lip portions covers approximate half one of the sidewalls of the tire in the radial direction.
The present invention will become clearer in light of the following detailed description of illustrative embodiments of this invention described in connection with the drawings.
The illustrative embodiments may best be described by reference to the accompanying drawings where:
A tire protection device of an embodiment of the present invention is shown in
The car with the tire protection devices 10 installed on the tires 2 for running on a road allows the external surfaces 15 of the annular walls 1 to replace the treads 21 of the tires 2 and to contact pavements without direct friction-induced wear between the tires 2 and pavements. In addition, the new tire protection device 10 substitutes for an old one removed because of the annular wall 1 worn and unserviceable to realize neither renewal of any tires nor the abandoned and environmental-unfriendly tires. On the other hand, the patterns 152 and the textures 151 on the annular wall 1 and the lip portions 11, 12 also optimize visual aesthetics of the tire 2.
Thus since the invention disclosed herein may be embodied in other specific forms without departing from the spirit or general characteristics thereof, some of which forms have been indicated, the embodiments described herein are to be considered in all respects illustrative and not restrictive. The scope of the invention is to be indicated by the appended claims, rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are intended to be embraced therein.
