A conventional tire assembly for vehicle wheel as shown in
1. Poor safety: When the tires are used in a vehicle to travel on the road, if the tires are punctured by a penetrating object, the inner tube of the tire will break and then become a flat tire, which will significantly cause a serious danger while the vehicle is running.
2. Inconvenience in operation: When the tire and the inner tube are punctured by the penetrating object, it takes a person to replace it with a new tire or repair the tire immediately. However, the process and operation of such replacement are complicated and difficult, so it causes some inconveniences in using the conventional tire.
Another conventional tire assemble as shown in
1. High manufacturing cost: The conventional tire comprises an integral foaming layer which made of rubber or plastic to become a solid form. Due to the high volume of the materials used to infill the tire, the manufacturing costs of such conventional tire are inevitably higher, which resulted in a higher selling price.
2. Inconvenience in operation: The conventional tire comprises an integral foaming layer inside which also contributes to such a heavy weight of the tire. When the tire is to be replaced or repaired for the purpose of maintenance, it will not be a convenience job to disassemble the tire due to such a heavy weight.
The present invention is intended to improve the above mentioned drawbacks of the conventional tire assembly. The present invention provides improved solutions to the problems of poor safety, inconvenience in operation and high manufacturing cost.
The primary purpose for the present invention is to provide a safety tire assembly, comprising: a tire and an annular tube, wherein the tire further comprises a mounting cavity where the annular tube is installed inside, the profile of which in circular and volute form, so that the annular tube will not break and result in a flat tire when punctured. Moreover, the manufacturing process of the tires for the present invention is very simple, so that the manufacturing costs can be reduced significantly. Meanwhile, the present invention is able to be used in an ordinary tire, to achieve the functions of safety use, convenience in operation and low manufacturing cost.
Other objects, advantages and novel features of the invention will become more apparent in the following detailed description taken in conjunction with the accompanying diagrams.
While this invention is capable of embodiment in many different forms, shown in the drawings and herein described in detail is the preferred embodiment of the invention. The preferred embodiment is disclosed with the understanding that the present description is but one example of the principles of the invention and is not intended to limit the broad aspects of the invention to the single embodiment illustrated.
The tire assembly comprises:
an annular tube 10, which is a solid and high sustained elastomer having a profile of a circular form comprising a volute structure 11, and the annular tube 10 is made of silica gel or Ethylene-Vinyl Acetate (EVA), namely to roll up to become the circular form by using the silica gel or the Ethylene-Vinyl Acetate (EVA); or optionally to roll up by using a gluey layer (not shown) installed inside of the silica gel or the Ethylene-Vinyl Acetate (EVA) which is in the form of slice, to become a fixed circular form; and
a tire 20 having securing edges 21 and a mounting cavity 22, wherein the mounting cavity 22 is used for installing the annular tube 10, and the securing edges 21 are used for securing a wheel rim 40. Meanwhile, the annular tube 10 and the tire 20 are set separately (as shown in
In light of the structural description stated above, the present invention fulfills a safety tire assembly thereof.
In the light of the above, the advantages of the present invention include:
1. High safety: Because the annular tube is an elastic annular form, when it is punctured by a penetrating object, the driver does not have to worry about the flat tire, the driving safety is therefore secured.
2. Convenience in operation: When the tire is punctured by a penetrating object, the driver has no difficulty in keep on driving the vehicle to a safe place to remove the penetrating object, and will not be distracted by the situation at that moment, so the operation of the tire assembly is convenient.
3. Cost saving: When the tire is punctured by a penetrating object, it only requires a person to remove the penetrating object instead of repairing or replacing the tire, so it has economical benefits and the advantage of cost saving.
Although numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, this disclosure is one example only, and changes may be made with regard to specific details, particularly in matters of shape, size, and arrangement of parts within the invention to the full extent indicated by the general meaning of the terms in which the appended claims are expressed.
