The present invention relates to a tread cover, and more particularly, to a tread cover for covering the tread is a pattern engraved on the ground plane of the tire to prevent slipping.

In general, tires make up the wheels of a car and support the load of the car. Then, the driving force or braking force generated in the vehicle is transmitted to the road surface to control the movement of the vehicle. It also mitigates the impact from the road surface and keeps the vehicle's direction of travel.

The tire has three parts: a carcass, a bead and a tread. The carcass is the skeleton of the tire and supports the load on the body, and the bead is the backbone of the tire. The end of the cord used for the carcass is wound at the end of the bead, which is fixed to the rim of the wheel.

In general, tires are made of durable rubber as the part directly contacting the road surface, and the tread is formed in a predetermined pattern on the surface of the tire to influence functions such as direction maintenance, cornering force, road surface maintenance performance, and brake performance. Therefore, the tread can be said to be important in the tire.

In general, as a medium-sized tire, treads tend to be irregularly worn, stamped, and fall off, which causes the tire body to be unable to use the entire tire, even though the tire body still has its durability.

Therefore, conventionally, in consideration of the conditions in which these tires are used, the tires that are inevitably a problem are disposed of, or they are collected by a factory equipped with a certain facility and recycled only by tread, but the tire price is quite expensive. In view of the fact and the bulk and weight thereof, and their collection, transportation and regeneration processes are cumbersome and time-consuming, the above-mentioned conventional methods always involve problems such as time and economic loss and compensate for these problems. There is a demand for tire types that can be made.

In order to solve the above problems, the conventional improved technology discloses a "tread replaceable tire" of Korean Patent Application No. 92-1040.

1 is a cross-sectional view showing a conventional tread replaceable tire.

As shown in FIG. 1, the circumferential grooves 1a and 2a and the circumferential protrusions are disposed in the circumferential direction of the tire so as to be engaged between the outer circumferential surface of the main body portion 1 of the tire and the inner circumferential surface of the tread portion 2, respectively. 1b) and 2b, and the left and right shoals are formed with axial grooves 2c and axial protrusions 2d in the axial direction of the tire and are coupled to each other.

However, although the axial grooves 2c and the axial protrusions 2d are formed in the axial direction of the tire in the left and right side shoals of the tread part 2 of the main body part 1, the main part 1 is formed in the shod part. The space between the portion 1 and the tread portion 2 is poorly bonded. Therefore, in the conventional tire, the circumferential grooves 1a and 2a and the circumferential protrusions 1b and 2b are actually coupled to each other, so that the tread portion 2 is removed from the main body portion 1 during sudden start or stop. There is a problem that turns out.

In addition, a conventional tread cover must replace the entire tread cover if a portion of the tread cover is worn or torn by another sharp edge. Therefore, although there is an economic advantage than the entire tire is replaced, the tread cover is also a state in which the remaining portion is not worn at all and is not damaged, resulting in waste of resources and economically disadvantageous. In addition, since the replaced tread cover is also treated by incineration or landfill, there is a problem of causing environmental pollution.

Accordingly, an object of the present invention for solving the above problems of the present invention is to provide a tread cover that can partially replace only the worn or damaged part of the tread cover.

Another object of the present invention is to provide a tread cover kit that is strongly coupled to the tire and the tread cover so that the tread cover does not turn away from or detach from the tire body even when the tire is transmitted with force.

It is yet another object of the present invention to provide a tread cover that can reduce waste of resources and reduce environmental pollution.

Still another object of the present invention is to provide a tread cover capable of continuously reusing a tire body.

According to a preferred embodiment of the present invention for achieving the above object of the present invention, in the tread cover for protecting the projection-shaped tread formed in a predetermined shape on the outer surface of the tire, the tread cover corresponds to the protruding outer surface of the tread It has a shape to have a cover body located on the outer surface of each tread to protect the individual tread. The tread cover may only be partially attached to the outer surface of the tread and may completely cover the tread.

Conventional tread covers cover the entire tread formed on the tire surface to form a new tread on the worn tread or to protect the existing tread as a whole. However, even if only a part of the newly covered tread cover is worn or scratched, the entire tread needs to be replaced, so that the unworn portion of the tread cover may need to be replaced together. This can be economically disadvantageous because of the waste of resources and the high cost of replacing the entire tread cover.

However, since the tread cover according to the present invention covers each tread individually, there is an advantage in that only a damaged tread cover can be replaced even if irregular wear, nailing, or falling off occurs. Therefore, in comparison with the conventional tread cover which must replace the tread cover as a whole, the tread cover according to the present invention can be economically advantageous in many respects because the replacement cost is low and the replacement work is simple.

In addition, since only a part of the worn tread cover is replaced, the amount of the tread cover that is discarded or discarded can be significantly reduced compared to the conventional method, thereby reducing environmental pollution.

The tread cover may generally be made of a resin-based material such as natural rubber and synthetic rubber, but may be made of metal only when used in quarries. At this time, the user can select the appropriate tread cover according to the environment in which the tire is used, and can replace the tread cover from time to time to optimize the work efficiency.

In particular, when the tread cover is formed of a rubber material, it is difficult to fix the tread cover to the tread and the tread cover may be torn in the process of using heavy equipment. At this time, the tread cover can be easily fixed to the tread by embedding or installing a connecting plate having at least one hole in the tread cover, and it is possible to prevent the tread cover from being torn by screws. The connecting plate is made of metal and the screws are fixed to the tread through the holes formed in the connecting plate.

According to another preferred embodiment of the present invention for achieving the above object of the present invention, the tire comprises a tread of a certain shape, the tread cover for protecting the tread, the tread cover kit is a cover body and fastening means It is provided.

The cover body has a shape corresponding to the outer surface of the tread and is located on the outer surface to protect each tread. The cover body may only be partially attached to the outer surface of the tread and may completely cover the tread. The fastening means is interposed between the cover body and the tread and binds the cover body and the tread together.

Since the conventional tread cover covers the tread portion of the tire as a whole, the tread cover rotates at a high speed while being subjected to a heavy load of the vehicle, so that the tread cover may turn over or escape from the tire during sudden start or stop. However, since the tread cover kit according to the present embodiment is strongly connected to the tread by a fastening means for each tread cover, the tread cover kit is safe from driving without being separated from the tire.

In addition, the fastening means may comprise a connecting plate and a connecting screw. The connection plate is embedded in one surface of the cover body, and at least one connection hole is formed in the center portion. The connecting screw is inserted into the connecting hole and penetrates into the inside of the tread to strongly connect the tread and the tread cover. However, in another embodiment of the present invention, the fastening means may use various fastening methods such as fastening means using an adhesive and fastening means connected to nails or metal materials according to a designer's intention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited or limited by the following embodiments.

Example 1

2 is a perspective view illustrating a tread cover kit according to a first embodiment of the present invention, and FIG. 3 is a cross-sectional view illustrating the tread cover kit according to the first embodiment.

2 and 3, the tread cover kit includes a cover body 120 and a fastening means 130. The cover body 120 is located on the outer surface of the tread 110 of the tire. The cover body 120 is manufactured in the same shape as the outer surface of the tread 110 to completely cover the outside of the tread 110. Accordingly, the cover body 120 includes four side wall plates 122 having a quadrangular shape surrounding the sides of the tread 110, and is connected to the tops of the four side wall plates 122 and covers the outer surface of the tread 110. A covering cover plate 124 is included. Accordingly, the cover body 120 is provided with a receiving groove 126, which is a space provided by the side wall plate 122 and the cover plate 124. Therefore, the tread 110 may be inserted into the receiving groove 126, and the inserted tread 110 is completely in contact with the cover body 120. However, in another exemplary embodiment of the present invention, only a cover plate connected to the tread 110 and in contact with the ground may be formed according to a designer's intention. In addition, the cover body 120 is made of a rubber material. Rubber can absorb the impact of the road surface because it can support the load of the car. However, in another embodiment of the present invention, the material of the cover body may be made of metal according to the intention of the designer when the road surface is severe, such as quarries.

The fastening means 130 is interposed between the tread 110 and the cover body 120 to fasten the tread 110 and the cover body 120. Since the tread 110 is in direct contact with the road surface, vibrations generated from the outside are severely transmitted. Therefore, when the cover body 120 is not strongly bound with the tread 110, a case in which the tread 110 and the cover body 120 are separated from each other by an external shock during driving may occur. Therefore, the adhesive is applied to the inner surface of the cover body 120 to strongly adhere to each other. Therefore, the plurality of cover bodies 120 are tightly adhered to the entire tire. However, in another exemplary embodiment of the present invention, various fastening means, such as fastening by means of screws and fastening means using various kinds of adhesives, may be used according to a designer's intention. In addition, when the tread cover is sold as a product, only the cover body 120 may be sold so that the user may directly fasten the tread cover or separately from an industrial company.

The tread cover kit according to the present invention replaces only the tread cover that is damaged because the cover body 120 is in close contact with each tread 110. Therefore, it is possible to obtain economical benefits as compared with the conventional tread cover in which the cover covering the entire tread portion is replaced, and the replacement time of the tire can be greatly extended.

In addition, the tread cover kit strongly connects between the tread 110 and the cover body 120 using an adhesive. Therefore, the tread 110 and the cover body 120 may be safely driven without an external impact.

The side wall plate 222 is formed with a through hole 222a penetrating from the outside to the inside. Therefore, the tread 210 is fixed by the connecting screw 234 through the through hole 222a. In addition, the cover body 120 is made of a rubber material. Rubber can absorb the impact of the road surface because it can support the load of the car. However, in another embodiment of the present invention, the material of the cover body may be made of metal according to the intention of the designer when the road surface is severe, such as quarries.

The fastening means 230 includes a connecting plate 232 and a connecting screw 234. The connecting plate 232 is embedded in the inner surface of the cover plate 224 in contact with the cover body 220 and the tread 210. The connecting plate 232 is inserted into the cover body 220 using an injection molding method. And, the connecting plate 232 is formed in a rectangular shape with a smaller size than the cover plate 224. However, in another embodiment of the present invention, the connecting plate may be formed in various shapes corresponding to the shape of the tread. In addition, the inner surface of the connecting plate 232 is provided with a connecting hole 232a at a position in contact with the through hole 222a. Therefore, the connection screw 234 penetrates through the connection hole 232a and is bound to the connection plate 232. Two connection holes 232a are formed at positions symmetrical to the inner surface of the connection plate 232, but the number of connection holes 232a is not limited to two. The connecting plate 232 is made of a metal material. The cover body 220 is made of a rubber material to obtain a cushioning effect, but in order to be connected to the tread 210 and the connecting screw 234, the connecting plate 232 is preferably made of a large metal material. The connecting screw 234 is positioned corresponding to the connecting hole 232a, and the two connecting screws 234 are secured to the tread 210 while being embedded in the inside of the tread 210 through the connecting plate 232. Therefore, the connection screw 234 prevents the cover body 220 and the tread 210 from being bound to each other to be separated from an external impact. The connecting screw 234 can be inserted from the outside of the cover body 220, so that the user can easily connect.

The tread cover kit according to the present embodiment strongly binds the cover body 220 and the tread 210 through the fastening of the connecting plate 232 and the connecting screw 234. Therefore, the cover body 220 and the tread 210 are prevented from being separated by an external shock. In addition, since the connection screw 234 is simple to connect to the cover body 220, the user can be easily fastened. Therefore, since it can be replaced at any place or time, it can be manufactured as a portable product.

6 to 8, the tread cover kit includes a cover body 320 and a fastening step 330.

The cover body 320 is located on the outer surface of the tread 310 of the tire. The cover body 320 includes four sidewall plates 322 surrounding the sides of the tread 310, and includes a cover plate 324 connected to the four sidewall plates 322 and covering the top of the tread 310. Include. In addition, the cover body 320 is provided with a receiving groove 326 which is a space provided by the side wall plate 322 and the cover plate 324. The side wall plate 322 is formed with a through hole 322a penetrating from the outside to the inside. A plurality of through holes 322a is formed to correspond to the connection holes 332a. In addition, the cover body 120 is made of a rubber material.

The fastening means 330 includes a connecting plate 332, a connecting screw 334, and a female screw part 336. The connecting plate 332 is embedded in the inner surface of the cover plate 324 in contact with the cover body 320 and the tread 310. The connecting plate 332 is connected to the three connecting plate 332 at regular intervals on the cover plate 324. The inner surface of the connecting plate 332 is provided with a connecting hole 332a at a position in contact with the through hole 322a. Two connection holes 232a are formed at positions symmetrical to the inner surface of the connection plate 232. In addition, the connecting plate 332 is formed with a fixing protrusion 332b protruding upward from the surface. The fixing protrusion 332b of the connecting plate 332 is embedded in the inner surface of the cover body 320 to fix the connecting plate 332 to the cover body 320. Therefore, the connecting plate 332 is prevented from falling off from the cover body 320 by the tire that moves in a circle while driving the vehicle. The connecting plate 232 is inserted into the cover body 220 using an injection molding method. In another embodiment of the present invention, however, the connecting plate may be inserted into the cover body from the outside according to the intention of the designer. Since the connecting plate 332 is made of a metal material, the cover body 220 and the tread 210 are strongly bound. The connection screw 334 is positioned corresponding to the connection hole 332a, and six connection screws 334 pass through three connection plates 332 to be connected to the internal female parts 336 of the tread 310. The female screw part 336 is embedded into the tread 310 from the side where the tread 310 and the connecting screw 334 meet. The female screw part 336 is formed in an unevenly curved shape so that the outer surface has a height difference when viewed from the outside. Therefore, when the female screw portion 336 tries to fall out by force to the outside, the outer surface is fixed to the inner material of the tread 310 without being detached. Therefore, the tread 310 and the cover body 320 can be more stably fixed.

Therefore, since the tread cover and the tread cover kit according to the present invention are individually covered on each tread, it is possible to obtain economic benefits by replacing only the tread cover that is damaged by irregular wear, stamping, or falling out.

In addition, the tread cover is strongly bound by the fastening means, so that the tread cover does not turn away from the tire body or provide a tread cover that helps safe driving.

In addition, since the connection screw is simply connected to the cover body, the user can easily fasten it so that it can be replaced regardless of place or time, and thus can be manufactured as a portable product.

In addition, since only the damaged portion of the tread cover can be replaced, it is possible to reduce the waste of resources compared to the conventional replacement of the tread cover as a whole, and the amount of worn tread cover can be reduced compared to the conventional one can reduce the environmental pollution. In addition, there is an advantage that the remaining tire body can also be used continuously without replacement.
