Description

  The present invention relates to a tire, and more particularly to an original structural form related to a tire sidewall reinforcing structure.

  In the design of the structure of a traditional tire, grooves and cuts are intensively carved into the tread surface of the tire, thereby improving drainage and slip resistance. The sidewall portions on both sides of the tire are usually provided in the form of flat annular surfaces.

  Since then, several structural forms have been developed in the related industry where grooves and cuts are cut into the tire sidewalls. However, these designs are usually used for decorative designs and advertisements and do not have any positive effect on the tire structure. Although there are a small number of patterns that have a protective effect on the sidewalls, these forms lack design considerations, making it difficult to use them for tire sidewalls as an ideal and practical reinforcement structure. is there. Therefore, it is an important technical problem to further improve them.

  The present invention aims to provide a tire sidewall reinforcement structure, and the problem to be solved is a new tire structure that is more ideal and practical due to the sidewall reinforcement structure provided outside the tire sidewall. Develop a form.

  As a technical feature for solving the problems of the present invention, the sidewall reinforcing structure includes a plurality of radial ribs provided at intervals along the circumference of the sidewall. Each radial rib is provided such that the extending direction coincides with the direction extending radially from the center of the sidewall toward the tire tread surface. There is a recess formed oppositely between adjacent radial ribs. The sidewall reinforcing structure includes one or more circumferential ribs provided adjacent to the recesses formed between the radial ribs. Both sides of each circumferential rib are integrally joined with a corresponding radial rib. The extending direction of each circumferential rib coincides with the circumferential rotation direction of the sidewall. It arrange | positions so that it may mutually replace between a circumferential direction rib and a radial rib. The positions of different circumferential ribs arranged adjacent to the recesses are provided so as to be offset from each other.

  Due to such an original design, the present invention is different from the background art in that the positions of the radial ribs and the circumferential ribs arranged to be interchanged with each other and the positions between the different circumferential ribs arranged adjacent to the recesses are mutually different. The excellent grid-like reinforcing ribs that are provided so as to be shifted in the direction of the tire provide excellent reinforcement effects in the radial and circumferential directions of the tire sidewall at the same time, greatly increasing the strength, durability and service life of the tire. It has practicality and inventive step.

  1 to 5 show preferred embodiments of the tire sidewall reinforcing structure of the present invention. These examples are used for illustration only, and the present invention is not limited to these structures.

  The sidewall reinforcement structure A provided outside the sidewall 11 of the tire 10 includes a plurality of radial ribs 20 provided at intervals along the circumference of the sidewall 11. Each radial rib 20 is provided so that the extending direction coincides with the direction extending radially from the center of the sidewall 11 toward the tread surface of the tire 10. There is a recess 21 formed oppositely between the adjacent radial ribs 20. The sidewall reinforcing structure A includes one or more circumferential ribs 30 that are respectively provided adjacent to the recesses 21 formed between the radial ribs 20. Both sides of each circumferential rib 30 are integrally coupled with the corresponding radial rib 20, and the extending direction of each circumferential rib 30 coincides with the circumferential rotation direction of the sidewall 11. The circumferential ribs 30 and the radial ribs 20 are arranged so as to be interchanged with each other, and the positions of the different circumferential ribs 30 arranged adjacent to the recesses 21 are shifted from each other.

  Each of the radial ribs 20 and the circumferential ribs 30 has a cross section provided in any one of a triangular shape, a semicircular shape, and a trapezoidal shape, and the circumferential rib 30 shown in FIG. The cross section of the circumferential rib 30 </ b> B shown is a semicircular embodiment.

  Each radial rib 20 is provided so as to protrude from the sidewall 11 of the tire 10 by about 1 mm to 10 cm or about 5 mm to 10 cm. The height at which the radial rib 20 protrudes in this embodiment varies depending on the reinforcement needs corresponding to the specifications of the tire 10 in actual application.

  As shown in FIGS. 1 and 2, in this embodiment, the sidewall reinforcing structure A is provided so as to be continuously arranged in an annular shape outside the sidewall 11 of the tire 10.

  As shown in FIG. 7, in this embodiment, the side wall reinforcing structure A <b> 2 is provided outside the side wall 11 of the tire 10 so as to be arranged in a ring shape with a gap.

  As shown in FIG. 3, in this embodiment, two circumferential ribs 30 adjacent to each other with a gap therebetween and two radial ribs 20 that are integrally joined to each other are provided with a recess 21 (note: this is the recess 21 described above). (The same reference numerals are used because of the same location) and are provided so as to surround a square shape. The “b-shape” in the present embodiment may be provided in any one of a rectangle, a square, a circle, and an ellipse when actually implemented.

  As shown in FIGS. 1 to 3, the different circumferential ribs 30 arranged adjacent to the recess 21 are provided so that the numbers thereof are different from each other and their positions are shifted from each other. For example, in this embodiment, it is composed of two circumferential ribs 30 and one circumferential rib 30, which are provided so that their positions are shifted from each other.

  Due to the structure, assembly and technical features described above, the tire sidewall reinforcement structure according to the present invention includes a plurality of circumferential ribs 30 and radial ribs 20 arranged so as to be interchanged with each other, and is adjacent to the recess 21. The positions of the different circumferential ribs 30 arranged so as to be shifted from each other are provided. As a result, an excellent grid-like reinforcing rib different from the side wall pattern form of the conventional tire is formed. The radial rib 20 has an elastic reinforcing and supporting action for the radial direction of the sidewall 11 of the tire 10 and the circumferential rib 30 for the circumferential direction 8 of the sidewall 11 of the tire 10. 30 and the radial rib 20 are interchanged with each other and have a grid-like structure that is arranged so as to be joined together. Therefore, durability is reliably improved by the rigidity and stability of the rib structure, and a practical and original sidewall 11 reinforcing structure of the tire 10 is formed.

  The “tire sidewall reinforcing structure” according to the present invention includes radial ribs and circumferential ribs, and the circumferential ribs and the radial ribs are arranged so as to be interchanged with each other, and are arranged in different circles adjacent to the recesses. It has an original structure form in which the circumferential ribs are provided so that the positions thereof are shifted from each other. Due to such an original design, the present invention is different from the background art in that the positions of the radial ribs and the circumferential ribs arranged to be interchanged with each other and the positions between the different circumferential ribs arranged adjacent to the recesses are mutually different. The excellent grid-like reinforcing ribs that are provided so as to be shifted to each other can simultaneously provide excellent reinforcing effects in the radial and circumferential directions of the tire sidewall, greatly increasing the strength, durability and service life of the tire There is practicality and inventive step that can be enhanced. Therefore, even if the tire is pressed or bounced back, the tire sidewall reinforcement structure according to the present invention provides effective reinforcement and elastic support effect, so the tire strength, durability and service life There is practicality and inventive step that can greatly increase
