BACKGROUND OF THE INVENTION
1. Technical Field
The present invention relates to a tire with a puncture-proof spare tire structure, which can be rapidly assembled and is adaptive to various tire types by using fine tuning, thereby ensuring driving safety.
2. Description of Related Art
Generally, tires can be categorized into regular tires that have an inner tube therein and tubeless tires without using an inner tube, both of which are not resistant to damages caused by external force. A tire with an inner tube is ready to work when the inner tube is inflated to expand an outer tube of the tire. Upon puncture by a knife or a sharp article, the tire becomes flat and unusable immediately, bringing the driver with much trouble, such as shoving the car. In the case such a tire gets punctured when the car using it is running fast, traffic accidents are likely to happen. On the other hand, tubeless tires are known to be able to defer the tire's complete flatness upon puncture, so as to provide sufficient buffer time for the driver to drive the car to a nearby repair workshop. While this buffering function does allow a driver with a damaged tubeless tire to safely arrive at a repair workshop, this function can also hinder a car driver from immediately noticing the tire damage as the tire pressure does not drop sharply. In this case, if the car driver is not aware of the tire damage drives his/her car in high speed or on a rugged road, the tire is likely to become unusable immediately and put the driver into the risk of a traffic accident that endangers his/her life.
In view of the shortcomings of the prior-art devices, the present inventor is concerned about the public traffic safety and has invented numerous novel tire improvements, including many that have been patented in many countries. Nevertheless, instead of being complacent about his achievements, the inventor continues to research and improve his patented inventions (as the inventor owns numerous applications and patents, the list is too long to be exhaustively named herein), and herein provides a further improved simplified structure that can be assembled rapidly in order to benefit the public in terms of driving safety.
The configuration, objectives, means and spirit of the present invention will be explained in detail in the following paragraphs and the accompanying drawing.
SUMMARY OF THE INVENTION
The present invention is directed to a tire with a puncture-proof spare tire structure. Particularly, the structure can be installed to a tire rapidly and is applicable to various tire types by using fine tuning. The spare tire structure makes the tire using the same puncture-proof. The tire has its two top inner edges formed with hooked portions for engaging with a spare tire body. Thereby the spare tire structure can be engaged with the hooked portions of the tire rapidly and arm the tire with puncture-proof ability.
The objective of the present invention is to provide such a puncture-proof structure, wherein the preassembled spare tire body is a C-shaped part that can be directly engaged with the hooked portions of the tire, thereby achieving rapid installation. Besides, a tire using the spare tire body is puncture-proof such that when punctured by sharp articles or knifes, the tire can still work to make safe arrival at a nearby repair workshop. This saves a car driver who has a flat tire from shoving the car along a high-traffic road and risking his/her life, thereby ensuring the public traffic safety.
The spare tire structure includes a spare tire body that is a C-shaped member and has its inner circular surface formed with a groove. The spare tire body also has locking blocks and ribs. The locking block has its top formed with a ridge. Each of the locking blocks has a locking hole. The first and last locking blocks each has a through hole. The spare tire body is a C-shaped member with its front and rear ends each provided with a combining block. The two combining blocks have threaded holes communicated with each other. The two combining blocks each have one lateral formed with a through hole.
The groove of the spare tire body of the spare tire structure has plural pairs of retaining holes for fittingly receiving the hooks of the V-shaped braces, so as to structurally strengthen the groove. Therein each of the retaining holes is an L-shaped hole.
The through holes of the first and last locking blocks of the spare tire body of the spare tire structure are fore a first brace seat and a second brace seat to assemble, respectively. The locking holes of the other locking blocks of the spare tire body are for a plurality of linking plates to assemble and thereby forming a string to structurally strengthen the spare tire body.
The spare tire body is a C-shaped member having its inner circular surface formed with a groove that is configured to engage with the hooked portions at the inner surface of the tire. With additional fastening components, the components can be assembled rapidly and firmly. When the tire is flat, the spare tire structure allows the tire to make safe arrival at a nearby repair workshop.
