Description

Bicycle tire for prevention punctuation}

The present invention relates to a punctureless bicycle tire, and more particularly, to a punctureless bicycle tire that is prevented from puncturing and can be stably driven even in rough conditions.

Generally, bicycles are used for various purposes such as leisure sports such as mountain bike, hobby, exercise, or use for commuting.

The structure of such a bicycle includes two front and rear wheels, which are mainly used as a front wheel and a rear wheel, a bicycle body that supports the front and rear wheels, a safety seat installed on the center of the bicycle body to seat the driver's buttocks, And a steering part provided at the front of the part to steer the front wheel.

Here, bicycle tires differ from automobile tires, so they are not able to use heavy and thick tires because they interfere with driving performance. Therefore, lightweight bicycle tires are used, in which air injection type tubes are inserted mainly inside. At this time, the tube is coupled to the rim while being inserted inside the tire, and air is injected into the tube.

However, there has been a problem in that the road surface state is not good during traveling on a bicycle, or the tube coupled to the inside of the wheel is damaged by sharp metal such as glass fragments or nails, causing a puncture in the tire. In addition, when the tire is damaged, the tube itself needs to be replaced, resulting in a loss cost, and a process for repairing and replacing the tire is troublesome.

On the other hand, a no-punk tire has been disclosed in which a non-puncture tube made of a compression sponge material is inserted and coupled to the inner side of a tire so as to be semi-permanently used without shock absorption and puncture during running.

Here, the no-punk tire has an advantage that puncturing does not occur during traveling due to the action of a compression sponge, but the compression sponge is pressed due to a load, so that a sufficient shock absorbing function can not be exhibited. That is, since the compression sponge has a low elastic force, when the load is larger than the elastic force, the shock absorbing force is lowered, and the ride feeling is lowered, and normal traveling is difficult.

On the other hand, when the tire of the bicycle in which the no-func tube is inserted is inserted into the rim along the tube insertion hole formed in the inside of the bicycle tire, the portion of the bicycle tire to be fitted to the rim is broken and must be restored to the original shape do.

However, since the tire of the bicycle in which the non-puncture tube is inserted, in which the elastic force is lowered by the compression sponge material, requires considerable external force of the worker in the process of inserting the tire into the rim, the work is difficult and troublesome.

That is, it is preferable that the pin provides a function for forming the rim portion 10 into a ring shape as described above. In addition, the fins may serve to reinforce the strength of the rim 10 within the rim 10.

Tire fixing walls 11 projecting upward from the engaging portions 12 are formed at both side ends of the rim portion 10. It is preferable that the end of the tire fixing wall 11 is formed with a step toward the center of the rim 10 and extends along the circumferential direction. At this time, it is preferable that the rim body 20 is coupled between the respective tire fixing walls 11. Both sides of the rim body 20 are caught by the edge of the tire fixing wall 11 along the circumferential direction so that the detachment of the rim body 20 is restrained and fixed to the rim 10 .

The rim portion 10 may be made of various metal materials such as aluminum and stainless steel in consideration of price and weight, but it is most preferable that the rim portion 10 is made of an aluminum alloy material so that the traveling speed of the bicycle becomes light. At this time, it is preferable that the rim portion 10 transmits the driving force generated by the bicycle driver to the ground via the tires, and also supports the load generated during the traveling from the weight of the driver and the weight of the bicycle body.

It is preferable that the rim body 20 is made of a solid synthetic rubber material so that its inner end is inserted into the engagement portion 12 to be inserted thereinto. Further, it is preferable that the rim body 20 is provided in a ring shape. Here, the solid shape means that the inside of the rim body 20 is filled with a material such as synthetic rubber. That is, unlike a conventional structure in which an air tube is inserted into a tire, the present invention is characterized in that the rim body 20 and the buffer tread 30, which are made of a solid synthetic rubber material, It is preferably inserted into the inside of the rim portion 10.

Accordingly, the process of inserting the air tube into the inside of the tire coupled to the rim portion is not substantially required, and the work process is completed by inserting the rim body 10 into the rim body 10, And the installation is simplified, so that the assemblability can be improved. At this time, the rim body 20 is preferably made of a synthetic rubber material, but may be made of natural rubber, synthetic resin, or the like. Therefore, since the rim body 20 is made of a material having excellent elasticity such as synthetic rubber, natural rubber, synthetic resin, etc., the impact is absorbed by the shock absorbing action, so that the riding feel at the time of driving can be increased.

 In addition, the rim body 20 may be formed by foaming a material such as synthetic rubber, natural rubber, or the like. At this time, since synthetic rubber, natural rubber and the like are made of foam by injection foaming method, press foaming method and the like, they are lightweight, durability is increased, and corrosion and aging can be prevented.

Accordingly, the rim body 20 is made of a solid synthetic rubber material, so that even if a sharp metal such as a piece of glass, nails, tack, or wire is inserted into contact with the rim body 20, There is no puncture, and the stability can be significantly increased. Also, even if glass pieces or sharp metal such as nails are inserted into the rim body 20, punctures do not occur. Therefore, replacement is not necessary and the cost of replacing the tire is reduced and the life of the tire can be remarkably increased.

In addition, the inner end of the rim body 20 may be inserted into the coupling portion 12 so as to be inserted thereinto. Preferably, a plurality of support protrusion lines 21 are formed on the outer circumference of the rim body 20 so as to be in line contact with the inner circumference of the engaging portion 12.

In more detail, the support projection line 21 is formed at a plurality of locations on the inner side of the inner side of the rim body 20 along the circumferential direction. Here, the support protrusion line 21 may be formed with a groove along the circumferential direction so as to correspond to the shape of the engaging portion 12. Alternatively, as the rim body 20 is inserted into the rim 10 and is closely contacted, the rim portion may be formed in a groove shape. In this case, when the rim body 10 is inserted into the rim 10, the rim body 20 is formed of an elastic body such as synthetic rubber, And can be pressed and brought into close contact with each other.

Here, the support protrusion line 21 may be held in line contact with the engaging portion 12 when the rim body 20 is inserted into the rim portion 10. When a strong external force acts on the tire during driving of the bicycle, the rugged rim body 20 is further pressed against the rim portion 10 so that the support projection line 21 is in surface contact with the engaging portion 12 It is possible. Thus, in a state in which the rim body 20 is inserted into the inside of the rim portion 10 by being in line contact or surface contact with the engaging portion 12 having a plurality of the supporting protrusion lines 21 The stability and running performance of the puncture-resistant bicycle tire 100 during traveling can be improved.

Also, the buffer tread portion 30 may be formed by foaming a material such as synthetic rubber, natural rubber or the like. At this time, since synthetic rubber, natural rubber, and the like are formed into a foam, they are lightweight, durability is increased, and corrosion and aging can be prevented.

Accordingly, the buffer tread portion 30 is made of a solid synthetic rubber material, so that even if a sharp metal such as glass fragments, nails, tacks, and wire is inserted into the buffer tread portion 30 and inserted therein, The puncture is prevented and the stability can be significantly increased. Also, even if glass pieces or sharp metal such as nails are inserted into the buffering tread portion 30, no punctures are generated. Therefore, replacement is not necessary and the cost of replacing the tire can be reduced and the lifetime of the tire can be remarkably increased.

The buffer tread portion 30 may be longer in the radial direction than the conventional tread. Accordingly, since the buffer tread portion 30 is formed of a thicker resilient material such as synthetic rubber than the conventional tread during traveling of the bicycle, the buffering force is increased and the ride feeling can be further improved.
