[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a string used for a tire slip stopper.

[0002]

2. Description of the Related Art Referring to FIGS. 3 and 4, an example of a non-slip device for a tire using a belt-shaped string according to the present invention will be described. ,
Hooks 4 are attached to the side of the slip stopper body 1 at regular intervals. The tightening string 14 has an adjusting tool 6 fixed to one end of the string body 5. The string body 5 is drawn in a loop, the other end is inserted through the adjusting tool 6, and a rubber string or the like is further attached to the end thereof. The biasing body 15 is connected, and the biasing body 15 draws a loop again, and its tip is connected to the adjusting tool 6. And
The non-slip device main body 1 is wound around the tire 2 and both ends of the fixing cord 3 fixed to the inner edge thereof are connected, and the adjusting device 6 is locked at both ends of the outer edge thereof, and is attached to the outer edge. The string body 5 is locked to the hook 4 and tightened, and the urging body 15 is again annularly formed to be sequentially locked and attached to the hook 4.

[0005] As shown in FIG. 5, such an adjusting tool 6 includes an arc-shaped holding portion 1 having an uneven surface on a side plate 8 of a main body 7.
0 is rotatably supported at its eccentric position at the eccentric position, so that the cord body 5 inserted between the holding portion 10 of the holding member 9 and the bottom 11 of the main body 7 is held. The holding member 9 is always urged by the spring means 12 in the holding direction. In this adjusting tool 6,
In FIG. 3, the cord body 5 can be easily moved in the left direction, that is, in the direction in which the non-slip device is tightened, but cannot be moved in the right direction, that is, in the direction in which the tightening is loosened, by being clamped by the holding member 9.
The tightening of the cord body 5 can be released by rotating the holding member 9 clockwise in the figure with the lever 13.

The adjuster 6 prevents the cord 5 from slipping in the loosening direction, and when the anti-slip device of the tire is loosened due to the running of the automobile, the elastic body of the urging member 15 causes the cord to become loose. 5 moves in the tightening direction and tightens strongly.
The looseness is naturally removed.

[0005]

Conventionally, as a fixing string 3 or a string body 5 in a non-slip device of this type, a regular 12-stroke or 16-stroke round string is conventionally used. In many cases, multifilament yarns or spun yarns of synthetic fibers have been used for the surface of these strings. As another structure, there is also used one in which synthetic fiber yarns are aligned or sweetly twisted to form a core, and a rubber or synthetic resin coating is formed on the surface of the core.

[0006] However, in the case of the above-mentioned round-hitting string, when the fiber of the surface texture is subjected to a strong external force, it is susceptible to damage or abrasion and is easily damaged. Is extremely easily damaged when it is tightened through the hook 4 or the adjusting tool 6, and is very easily damaged.

To explain this point in more detail, FIG. 6 shows the relationship between the hook 4 and the round string 5, for example. Will be subjected to great power. This is illustrated in FIG.
It is needless to say that the same applies to the adjustment tool 6 in the above, and that the holding portion 10 between the round string body 5 and the holding member 9 is in point contact. From these facts, it has been found that when the round cord body 5 is used as a non-slip cord of a tire, there is a disadvantage that the durability is significantly reduced.

On the other hand, it has been pointed out that a round cord body is adopted as a non-slip cord of a tire, and when the tire is attached to the tire, it is easy to loosen during running. That is, when this cord is applied to the cord 5 in the non-slip device of the tire, the cord 5 is rigid by coating and has elasticity. As shown by the solid line in FIG. 7, the portions between the hooks 4 are attached in a slightly curved state, and even if they are tightened no matter how much, the portion between the hooks 4 does not become linear, and this curvature remains loose.

Therefore, when the automobile is driven in this state,
The rotation of the tire causes a centrifugal force to act on the anti-slip device of the tire, and the looseness extends linearly, whereby the anti-slip device of FIG.
As shown by the chain line, there is room for the antiskid device of the tire to expand, and the antiskid device body 1 is loosened relative to the tire 2 by that much. In addition, since the looseness is caused by the structure of the string body 5 itself, it is difficult to pull and tighten the end of the string body 5, and the string body 5 is not tightened by the urging body 15.

The present invention has been made in view of the above circumstances, and is intended to be a non-slip device for a belt-shaped tire which is flexible, does not loosen, and has excellent abrasion resistance, trauma resistance and durability. The purpose is to provide a string.

[0011]

Means for Solving the Problems The present invention has been made in order to achieve the above-mentioned object, and has a flat core structure made of high-strength low-elongation fiber extending substantially in the longitudinal direction. The present invention relates to a belt-shaped tire anti-slip device cord which is characterized in that synthetic fibers are covered with a bag-shaped braided or woven surface texture, and preferably, the synthetic fibers constituting the surface texture are monofilament fibers. An anti-slip cord for a tire.

[0012]

The cord for the anti-slip device of the tire according to the present invention is in the form of a belt, and has a flat core structure and a surface structure. The core structure is made of a flat high-strength low-elongation fiber, and the high-strength low-elongation fiber is in a non-twisted or extremely twisted state and extends in the length direction of the cord.

[0013] The core structure is made of high-strength low-elongation fiber, does not extend while bearing the strength, holds the anti-slip device of the tire tightly to the tire, and inflates the anti-slip device of the tire due to centrifugal force. Multifilament yarns such as aramid fibers, glass fibers, and carbon fibers are usually used as the high-strength, low-elongation fibers constituting the core structure. Also, high strength,
Multifilament yarns such as low elongation type polyester fiber, nylon fiber, polyethylene fiber and polyvinyl alcohol fiber can also be used.

The surface texture is preferably excellent in abrasion resistance and trauma resistance, is not damaged even when subjected to friction with an adjusting tool or the like, and is excellent in durability. This surface texture is made of synthetic fibers such as nylon, polyester and polyethylene, and particularly preferably monofilament yarn.
Among them, nylon yarn is particularly suitable because of its excellent properties such as flexibility, abrasion resistance, and scratch resistance.

[0015]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is a partially cutaway perspective view of a strap 16 for a non-slip device of a belt-shaped tire according to the present invention. The core structure of the cord body is formed by using the high-strength low-elongation fiber 19 as a core yarn, 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 structure 18 is formed by weaving a monofilament yarn 20 as a warp yarn and weaving an appropriate yarn as a weft in a vertical opening weave structure to form the surface structure 18. The monofilament yarn 20 as a preferred example of forming the surface texture 18 has a diameter of 0.1 to 0.5 mm.
(About 100 to 20 for nylon monofilament yarn
About 00d) is appropriate. If this is excessively thin, the abrasion resistance is inferior.
Become rigid, and the above-mentioned loosening is likely to occur.

FIG. 2 is a cross-sectional view showing an example in which the strap 16 of the belt-shaped tire obtained by the present invention is hooked on the hook 4. As shown, the string 1 of the present invention
The contact between the hook 6 and the hook 4 is a surface contact, and there is no concentration of force, so that the durability of the anti-slipping cord 16 of the tire is improved. Although not shown, even when the belt-shaped tire anti-slip strap of the present invention is used as the adjusting tool 6 shown in FIG. 5, the belt-shaped cord 5 (16) and the holding member 9 are used. Is in 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, the cord 16 is easily mounted in a straight line while maintaining flexibility as the cord 16, so that there is no slack. Since the elongation is prevented, even when the tire rotates at a high speed and a large centrifugal force acts thereon, the anti-slip device of the tire does not expand and loosening does not occur.

[0018]

According to the present invention, therefore, the tire is arranged at a straight line between the hooks at the time of mounting so that there is no looseness and the extension is prevented by the core structure, so that the tire rotates at a high speed and a large centrifugal force is applied. Does not cause the tire anti-slip device to swell and does not loosen.

Further, in the present invention, when the surface texture is a monofilament yarn, the frictional resistance when passing through the adjusting tool when tightening the cord through the adjusting tool is small,
Also, it is easy to slip on the hook, so it can be tightened strongly, and even when loosened during use, it can be easily tightened through the adjusting tool with a small pulling force by the biasing body, eliminating slack. Can be. In addition, the absorption of water into the cord is small, and the drainage is good, so that it is not hardened due to freezing and it is not difficult to handle.
