Abstract

(57) [Summary] [Structure] A tire slip that is attached to a tire at one end of a non-slip net with a hook attached at regular intervals to tighten the anti-slip net on the tire. The stopper belt is composed of a hollow weave structure of multifilament yarns obtained by binding a large number of filaments with an adhesive.

It is superior in strength and abrasion resistance compared to anti-skid belts that use filament yarn.

Description

[Detailed description of the device]

[0001]

[Industrial application]

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

[0002]

[Prior Art]

 FIG. 5 shows a main part of a general tire slip stopper. FIG. 5 is a perspective view showing a part of the anti-skid net 1 mounted on the tire in the longitudinal direction. In FIG. 5, metal hooks 2 are attached to the end of the non-slip net 1 on the outside of the tire at predetermined intervals. The tire 3 is tightened by connecting both ends of the net 1 and the belt 3 into a ring shape while the elastic hook stopper belt 3 is hooked on the hook hook 2. An enlarged view of the state where the belt 3 is hooked on the hook 2 is shown in FIG. The bottom portion and both side portions of the belt 3 are in contact with and hooked on the hook portion 4 of the hook 2.

The belt 3 is generally composed of a core structure extending in the length direction and a surface structure composed of a hollow weave structure of multifilament yarn covering the outer periphery of the core structure.

[0004]

[Problems to be solved by the device]

 However, since the surface of the belt 3 is repeatedly moved or bent in the direction of the arrow in FIG. 6 when it is attached to the tire or when it is running, the multifilament yarn on the surface of the belt 3 forming the contact surface with the hook 2 is Wear out. When the bonds between the filaments are weakened due to the abrasion of the multifilament yarn, the filaments constituting the multifilament yarn are separated, and the filaments are sequentially cut, and finally the belt 3 is cut.

On the other hand, it may be possible to form the surface of the belt 3 with a thick monofilament yarn. However, since the monofilament yarn is generally inferior in strength to a multifilament yarn having the same thickness, a belt composed of the multifilament yarn is used. To obtain the same strength, the width and thickness of the belt must be increased. The present invention has been made to solve such a problem, and its object is to provide a multi-filament yarn even if the surface is worn, even though the surface is made of multi-filament yarn. An object is to provide a belt for a non-slip device in which filament yarn is not frayed.

[0006]

[Means for Solving the Problems]

 The anti-skid belt of the present invention is fastened to the tire by attaching the anti-slip net to the tire by hooking the anti-slip net on one end of the anti-slip net at regular intervals. A belt for a tire slip stopper is formed of a hollow weave structure of multifilament yarn in which a large number of filaments are fixed with an adhesive.

[0007]

[Action]

 Since the multifilament yarns constituting the surface of the anti-slip belt of the present invention are firmly bonded to each other by the adhesive, some of the filaments are worn by rubbing with the hooks. The multifilament yarn does not fray even when broken, preventing the belt itself from cutting and maintaining the initial strength and flexibility.

[0008]

【Example】

 The anti-skid belt of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of an anti-skid belt 5 according to an embodiment of the present invention, and FIG. 2 is a sectional view taken along the line AA of FIG. In the figure, the anti-slip belt is formed of a tubular weave structure in which the multifilament yarn 6 is used as warp yarns and weft yarns and is woven into a tubular or bag shape. Each of the multifilament yarns 6 used here has a structure shown in FIG. 3, that is, a structure in which a large number of filaments 7 are fixed with an adhesive 8.

As the filaments 7 constituting the multifilament yarn 6, synthetic fibers such as aramid fibers, polyester fibers, polyethylene fibers, polyamide fibers, inorganic fibers such as carbon fibers, and combinations thereof are used. The thickness of each filament is about 6 to 30 denier, and the thickness of the multifilament yarn 6 is about 210 to 1680 denier.

The adhesive 8 used in the present invention can be appropriately selected depending on the type of filament such as phenol resin, isocyanate compound, and epoxy resin. Since the filaments 7 of the multifilament yarn 6 are firmly bonded to each other with the adhesive 8, even if some of the filaments 7 are worn and broken, the multifilament yarn 6 does not fray and the number of filaments 7 simply decreases. Can be present as the multifilament yarn 6 formed. The anti-slip belt made of the multifilament yarn 6 having a hollow weave structure has the same strength as the belt having a smaller width and thickness as compared with the case where the surface structure is made of monofilament yarn having the same diameter. Can be obtained. Moreover, unlike the conventional multifilament yarn in which a large number of filaments are simply twisted, cutting of some filaments does not become a factor that accelerates cutting of the remaining filaments, so that the initial strength can be maintained.

Compared with the conventional anti-skid belt having the above-mentioned structure, the anti-skid belt is superior in wear resistance and strength to the conventional anti-skid belt using the multifilament yarn that is not hardened with an adhesive. .. Further, even when compared with a belt for a non-skid device having the same shape and the same size in which the surface structure is made of monofilament yarn, the abrasion resistance is about the same, and this example is superior in terms of strength. Further, when compared with a single rope in which all the filaments are hardened with an adhesive, the anti-skid belt of this example woven with threads treated with an adhesive has the threads tied together. Since it is easy to bend due to slipping between threads, it has excellent flexibility. Therefore, the work of mounting the anti-slip device on the tire becomes easy.

The anti-skid belt of the present invention has the necessary and sufficient strength without the core structure as in the above-mentioned embodiment, but like the conventional anti-skid belt, it is shown in FIG. Thus, if the core structure 10 made of the high-strength fibers 9 aligned in the length direction of the belt in the unwoven or untwisted state is present inside the hollow weave structure, the strength is further increased. preferable.

Next, another embodiment of the anti-skid belt of the present invention will be described with reference to FIG. As the multifilament yarn 12 forming the anti-slip belt 11 shown in FIG. 4, three multifilament yarns 6 shown in FIG. 3 are combined and further hardened with an adhesive 13. When a plurality of multifilament yarns 6 are combined in this way, the connection between the individual filaments becomes stronger and the strength of the belt as a whole is improved.

[0014]

[Effect of the device]

 In the tire anti-skid belt of the present invention, even if a part of the filaments that make up the multifilament yarn is cut by sliding with the hook, by firmly solidifying the individual filaments with the adhesive, It is possible to prevent other fillers from being sequentially worn and cut. Therefore, the tire anti-skid belt of the present invention has a strength equal to or higher than that of the conventional anti-skid belt having a surface texture composed of multifilament yarns in which a large number of filaments are not fixed with an adhesive. Moreover, it has excellent wear resistance.
