Abstract

PURPOSE:To enhance anti-breakage quality by forming a cord compound material whose core body of a low elongation quality is covered with a surrounding rubber layer, into the state of a double loop of the same diameter, and binding both side end portions of the compound material in a loop state on one side to the compound material of a loop shaped body on the other. CONSTITUTION:This tightening band 10 comprises a piece of compound material 12 and 2 pieces of connectors 20. The compound material 12 is made to be of a cord shape whose rubber layer 14 covers the perimeter of a core body 13 made up of a cord or braid of a low elongation quality, and is formed into bodies 15a, 15b of a double loop shape lying one upon the other in the same diameter. The required tightening band 10 is obtained by making both side terminals of the compound material 12 of the loop shaped body 15a on one hand cross at one place so that they may be joined together in opposition on the same side surface of the compound material 12 of the loop shaped body 15b on the other, and then, binding both end portions 16, 17 of the compound material 12 forming the loop shaped body 15a on one hand against the compound material 12 forming the loop shaped body 15b on the other by means of respective connectors 20.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a tightening band that prevents a non-metallic tire skid device from spreading due to centrifugal force generated when the tire rotates.

[Prior Art] Conventionally, when attaching a non-metallic tire skid device to a tire,
The mounting rope on the front side of the tire is tightened with two or three ring-shaped rubber bands.

[Problem that the invention seeks to solve]

The rubber bands conventionally used to tighten tire cleats have a large elongation due to their rubber elasticity, so if a band with a weak tightening force is used, the cleats will expand due to centrifugal force when the tire is running at high speeds. This can cause not only damage to the anti-skid device due to contact with structures such as the tire house and shock absorber of the vehicle body, but also damage to the vehicle body structure.

In addition, in order to prevent the skids from spreading due to centrifugal force when the tire is running at high speed, using a rubber band with a strong tightening force will reduce the slippage of the skids between the tires.
In addition to making the tire more susceptible to damage, the durability of the anti-skid device decreases, and there are also problems in that the rubber band is difficult to attach and detach.

This invention solves the above-mentioned problems and makes it possible to install a non-slip device with a moderately strong tightening force, and to prevent the non-slip device from spreading due to centrifugal force when the tire rotates. The purpose is to provide bands.

[Means for solving problems]

The non-metallic tire skid tightening band of the present invention is made of a string-like composite material consisting of a low-stretch cord or braid as a core and a rubber layer coated around the core, which intersect at one point and are identical. Form a double loop-like body that overlaps in diameter, and connect each end of the composite material of one loop-like body, in which the opposite ends of the composite material are joined together, to the composite material of the other loop-shaped body that overlaps this. It has a structure in which two loop-shaped bodies are connected together.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view showing an example of a tightening band IO of the present invention, and FIG. 2 is a perspective view thereof.

The tightening band 10 of this embodiment is a single string-like composite material 12.
and two connectors 20.

As shown in the cross-sectional view of FIG. 4, the composite material 12 is a string-like material in which a low-stretch cord or braid is used as a core body 13 and a rubber layer 14 is coated around the core body 13. A double loop-shaped body 15a overlapping the material 12 with the same diameter,
15b, and the composite material 12 of the negative loop-shaped body 15a.
The both ends of the loop-shaped body 15b are crossed at one place so that they are joined together facing each other on the same side of the composite material 12 of the other loop-shaped body 15b (see FIG. 2).

The ends 16, 17 on both sides of the composite material 12 forming one loop-shaped body 15a are connected to the composite material 12 forming the other loop-shaped body 15b through connectors 20, respectively, as shown in FIG. It is concluded that

The connecting tool 20 is a metal fitting having a groove-shaped cross section that is large enough to accommodate two composite materials arranged in parallel in its original shape. , 17 and the other overlapping composite material 12 are inserted, and both side walls of the connector 20 are pressed and caulked.
As shown in FIG.
, 17 and the other composite material 12 that overlaps them are bound together, resulting in a state in which the double loop-shaped bodies isa and 15b are integrally connected.

As the core body 13 constituting the above-mentioned composite material 12, it is preferable to use a cord or braid made of lightweight fibers with high tensile strength, such as synthetic fibers such as 66 nylon and polyester. Steel fiber cords can also be used if desired.

FIG. 6 shows a tire 2 using the tightening band 10 of the present invention.
5 shows a state in which the ladder-shaped anti-skid device 30 attached to the tire is tightened on the front side of the tire.

The procedure for attaching the anti-skid device 30 to the tire 25 will be explained as follows.
First, hooks provided at both ends of the rope for attaching the anti-skid device 30 are hooked together on the back side of the tire 25 (not shown). Next, after hooking the hooks at both ends of the mounting row 131 of the anti-slip device 30 on the front side of the tire 25, a conventional rubber band 40 is hung on the hook 32 attached at a distance to the mounting rope 31. Stop and tighten the anti-slip tool 30.

One conventional rubber band 40 having an appropriate tightening force may be used.

The tightening band 10 of the present invention is formed in advance into a loop-shaped body having a circumference approximately equal to the entire length of the rubber band 40 used for tightening the anti-slip device 30 in an expanded state. The hook 32 of the rubber band 40, which is hooked to the stopper 30, is hooked to the tightening band 10.

〔Effect of the invention〕

As explained above, the non-metallic tire skid tightening band of the present invention consists of two loops of the same diameter, a string-like composite material in which a rubber layer is coated around a low-stretch core. It is formed into a shaped body, and both ends of the composite material of one loop-shaped body are tied to the composite material of the other loop-shaped body to form an integral structure.
Its structure has extremely low elongation under tension and no risk of breakage. Therefore, in the tightening band of the present invention, elongation is suppressed even when the anti-skid device is subjected to centrifugal force when the tire runs at high speed, so the spread of the anti-skid device is reduced, and slippage due to contact with the vehicle body structure is suppressed. The risk of breakage of the stop and damage to the vehicle body structure is reduced, and reliability during high-speed driving is increased.

Furthermore, according to the present invention, the rubber band used in combination with the tightening band can have an appropriate tightening force, thereby ensuring an appropriate amount of slippage between the anti-slip device and the tire. This not only reduces tire damage, but also significantly increases the durability of the anti-skid device.

Furthermore, since the tightening band of the present invention can have a large outer diameter in accordance with the elongation of the rubber band, it can be easily attached and detached.

Furthermore, since the tightening band of the present invention can be manufactured by covering the core with a rubber layer by extrusion molding and continuously vulcanizing, the tightening band is highly productive and inexpensive to manufacture. can get.
