 The present invention relates to a string used for a tire slip stopper.

[0002]

[Prior art]

 An example of the anti-skid device for a tire using the belt-shaped cord of the present invention will be described with reference to FIGS. 3 and 4. The anti-slip device includes the anti-skid body 1 and the tightening string 14 which are separate bodies. Hooks 4 are attached to the side portion of the main body 1 at regular intervals. The tightening string 14 has an adjusting tool 6 fixed to one end of the string 5, the loop 5 drawing a loop, and the other end is inserted through the adjusting tool 6, and the tip of the tightening string 14 is attached with a rubber string or the like. The urging body 15 is connected, and the urging body 15 draws a loop again, and its tip is connected to the adjusting tool 6. Then, the anti-slip body 1 is wound around the tire 2, and both ends of the fixing cord 3 fixed to the inner edge of the anti-slip body are connected, and the adjusting tool 6 is locked to both ends of the outer edge thereof. The cord 5 is locked to the hook 4 attached to the outer edge and tightened, and the urging body 15 is again made into an annular shape so as to be sequentially locked and attached to the hook 4.

As shown in FIG. 5, the adjusting tool 6 rotatably supports a holding member 9 in which a side plate 8 of a main body 7 is formed with an arc-shaped holding portion 10 having an unevenness on its outer periphery, at its eccentric position. The cord 5 inserted between the holding portion 10 of the holding member 9 and the bottom portion 11 of the main body 7 is held, and the holding member 9 is attached in the usual holding direction by the spring means 12. It is energized. In this adjuster 6, the string 5 can be easily moved on the left side in FIG. 3, that is, in the direction in which the anti-slip device is tightened, but it is moved by being tightened by the holding member 9 in the direction in which the right-side tightening is loosened. However, the tightening of the string body 5 can be released by rotating the holding member 9 in the clockwise direction in the figure with the lever 13.

The adjuster 6 prevents the cord 5 from slipping in the loosening direction, and when the tire anti-skid is loosened due to the running of the vehicle, the elastic force of the biasing body 15 causes the cord 5 to move. It is said that the body 5 moves in the tightening direction and tightens strongly, and the looseness is naturally removed.

[0005]

[Problems to be solved by the device]

 Conventionally, as the fixing cord 3 and the cord body 5 in this kind of tire anti-skid device, a round striking cord such as 12 striking or 16 striking is usually used, and the surface of these cords is composed. Multifilament yarns or spun yarns of fibers have been used. As another structure, one in which synthetic fiber yarns are aligned or sweetly twisted to form a core body and a coating of rubber or synthetic resin is formed on the surface of the core body is also used.

However, in the case of the above-mentioned round striking string, when the fibers of the surface structure are subjected to a strong external force, they are easily damaged or damaged by the external damage, and particularly in the case of the string 5 in the above-mentioned tire anti-skid device. Receives a strong external force when it is tightened through the hook 4 and the adjusting tool 6, and is extremely easily damaged.

Explaining this point in more detail, for example, the relationship between the hook 4 and the round cord 5 is shown in FIG. 6, but since the round cord 5 makes point contact with the surface of the hook 4, it is partially It will take a great deal of force to. This also applies to the adjuster 6 in FIG. 5, and it goes without saying that the pinching portion 10 between the round cord body 5 and the pinching member 9 makes point contact. From these, it is known that when the round cord body 5 is used as a cord for a tire anti-skid, there is a drawback that the durability is significantly lowered.

On the other hand, it has been pointed out that a round cord body is adopted as a cord for a slip stopper of a tire and is easily loosened during traveling when the cord is attached to the tire. That is, when this string is applied to the string body 5 of the anti-skid device of the tire, since the string body 5 is made rigid by the covering and has elasticity, when it is attached to the anti-slip device body 1 in an annular shape, the hook 7 is attached in a slightly curved state as shown by the solid line in Fig. 7, and no matter how tightly tightened, the portion between the hooks 4 does not become a straight line, and this curve remains loose. is there.

Therefore, when the automobile is run in this state, centrifugal force acts on the anti-skid device of the tire due to the rotation of the tire, and the loosened portion extends linearly, so that the tire as shown by the chain line in FIG. There is room for the anti-skid device to swell, and the anti-skid device body 1 loosens with respect to the tire 2 by this amount. Moreover, since this looseness is caused by the structure of the cord body 5 itself, it is difficult to pull and tighten the end portion of the cord body 5, and the urging body 15 does not tighten it.

The present invention has been made in view of the above circumstances, and is a belt-like tire anti-skid device that is flexible and does not loosen, has excellent wear resistance and external damage resistance, and is durable. The purpose is to provide a cord.

[0011]

[Means for Solving the Problems]

 The present invention has been made in order to achieve the above-mentioned object, and a flat core structure made of high-strength and low-extension fibers extending in the longitudinal direction is braided with synthetic fibers in a bag shape. The present invention relates to a belt-like non-skid strap for a tire, which is covered with a woven surface texture, and preferably for a tire non-slip tire in which the synthetic fiber constituting the surface texture is a monofilament fiber. It is a string.

[0012]

[Action]

 The cord for the anti-skid device of the present invention itself has a belt shape, and the core structure has a flat plate shape and is covered with a surface structure. The core structure is composed of a flat plate-shaped high-strength low-elongation fiber, and the high-strength low-elongation fiber is untwisted or twisted and is extremely sweet, and extends in the length direction of the cord. .

The core structure is made of high-strength and low-elongation fibers, does not extend by bearing the strength, keeps the tire anti-slip device fastened to the tire, and prevents the tire anti-slip device by centrifugal force. As a high-strength, low-elongation fiber that constitutes the core structure, a multifilament yarn such as aramid fiber, glass fiber, carbon fiber, etc. is usually used as the high-strength, low-elongation fiber. used. In addition, high-strength, low-elongation type polyester fibers, nylon fibers, polyethylene fibers, polyvinyl alcohol fibers, and other multifilament yarns can also be used.

Further, the surface texture is preferably excellent in wear resistance and external damage resistance, is not damaged even when it is rubbed by an adjusting tool or the like, and is excellent in durability. This surface structure is made of synthetic fibers such as nylon, polyester and polyethylene, and it is particularly preferable to use monofilament yarn. Among them, nylon yarn is excellent in various properties such as flexibility, abrasion resistance and trauma resistance. It is especially suitable.

【Example】

 Hereinafter, the present invention will be described in more detail with reference to the drawings. FIG. 1 is a partially cutaway perspective view of a belt-like tire anti-skid string 16 of the present invention. The core structure of the cord is a high-strength, low-elongation fiber 19 used as a core thread, which is formed into a flat plate shape. In this example, the front structure and the back structure of the surface structure 18 are joined to form a belt. On the other hand, the surface texture 18 is formed by weaving a monofilament thread 20 as a warp thread and using an appropriate yarn as a weft thread in a warp weave design to form the surface texture 18. As a preferable example of the monofilament yarn 20 forming the surface texture 18, a diameter of 0.1 to 0.5 mm (about 100 to 2000 d in the case of nylon monofilament yarn) is suitable. If it is excessively thin, it is inferior in wear resistance. On the other hand, if it is excessively thick, the string 16 becomes rigid and the aforementioned looseness is likely to occur.

FIG. 2 is a cross-sectional view showing an example in which the belt-like tire anti-slip cord 16 obtained by the present invention is hooked on the hook 4. As shown in the figure, the contact between the cord 16 and the hook 4 of the present invention is a surface contact, and there is no concentration of force, and the durability of the cord 16 for the anti-skid device of the tire is improved accordingly. Although not shown, even when the belt-like tire anti-skid strap of the present invention is used for the adjuster 6 shown in FIG. 5, the belt-like strap body 5 (16) and the holding member 9 are provided. The sandwiching portion 10 between and becomes a surface contact, and the durability of the cord body is improved.

Further, since the cord body 16 is in the form of a belt, even if it is between the hooks 4 and 4, the cord 16 can be easily attached in a straight line while ensuring the flexibility, so that there is no looseness and the core tissue 17 Since the extension is prevented, even if the tire rotates at a high speed and a large centrifugal force acts, the anti-skid device of the tire does not swell and the tire does not loosen.

[0018]

[Effect of device]

 Therefore, according to the present invention, since the tires are linearly arranged between the hooks at the time of mounting and are not loosened, and the extension is prevented by the core tissue, the tire rotates at a high speed and a large centrifugal force acts. However, the anti-skid tires will not swell and will not loosen.

Further, in the present invention, when the surface tissue is a monofilament thread, the frictional resistance when passing through the adjusting tool when tightening the string through the adjusting tool is small, and it is easy to hook. Since it slides, it can be tightly tightened, and even when it is loosened during use, it can be easily tightened through the adjuster with a small pulling force by the biasing body, and the looseness can be removed. In addition, since there is little absorption of water into the inside of the cord and the water is drained well, it does not freeze and become hard and difficult to handle.
