The space 18 is served as a hook engaging part 18 of a rope for mounting the antiskid tire. With this arrangement, it is possible to facilitate attachment/detachment of the tighten band.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a tightening band that improves the tightening force and ease of attaching and detaching a non-metallic tire skid device when it is attached to a tire.

[Conventional technology]

Conventionally, one or more rubber bands have been used when tightening a non-metallic tire stopper via a tire attachment rope.

[Problem that the invention seeks to solve]

Conventional tightening rubber bands for tire skids have been found to elongate due to centrifugal force when the tire is running at high speeds, causing the skids to expand and separate from the tire, causing damage to tire houses and shock absorbers. Not only can the non-slip tool be damaged by contact with other vehicle body structures, but it may also cause damage to the vehicle body structure.

In addition, in order to prevent the non-slip device from spreading due to centrifugal force,
If a rubber band with strong tightening force is used, there will be less slippage between the skid and the tire, which will not only damage the tire, but also reduce the durability of the skid and make it difficult to attach and remove it. The problem is that it gets worse.

The object of the present invention is to solve the above-mentioned problems and provide a tightening band that has an appropriate tightening force when a non-metallic tire skid is attached to a tire and is easy to attach and detach. do.

[Means for solving problems]

The tightening band for a non-metallic shaft stopper of the present invention is made of an inner band part in which the surface of a circular reinforcing cord is coated with a rubber layer, and a circular rubber part with a larger diameter than the inner band part. The outer band portions are concentrically connected by connecting rubber portions arranged at predetermined intervals in the circumferential direction, and a space is formed between the inner and outer band portions via the connecting rubber portions. This is the hook latching part for the tire mounting robe of the anti-skid device.

〔Example〕

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

FIG. 1 is a plan view showing an embodiment of the tightening band 10 of the present invention, in which a circular inner band portion 12 and an outer band portion 16 are connected to a connecting rubber portion 17 arranged at equal intervals in the circumferential direction.
They are concentrically connected via.

As shown in the partially enlarged perspective view of FIG. 2 and the enlarged sectional view of FIG. 3, the inner band portion 12 is formed into a circular shape by covering the surface of the reinforcing cord 13 with a rubber layer 14 having a circular cross section.
The outer band part 16 is made of rubber having the same outer diameter as the rubber layer 14 of the inner band part 12 and is formed into a circular shape having a larger diameter than the inner band part 12.

As the reinforcing cord 13 of the inner band portion 12, it is preferable to use a lightweight fiber having high tensile strength, for example, a synthetic fiber such as 66 nylon or polyester.

The connecting rubber portion 17 that connects the inner band portion 12 and the outer band portion 16 is formed to have a thickness and width that are approximately the same as the outer diameter (rubber diameter) of the cross section of the inner band portion 12 .

In order to suppress elongation, it is desirable that the width of the connecting portion 17 is wide.

Between the inner band part 12 and the outer band part 16, 14 spaces with substantially equal lengths in the circumferential direction are formed via a connecting rubber part 17, and these spaces are used as tire attachment ropes of the anti-skid device. It is a hook holding part 18. Regarding the number of hook latching parts 18, it is sufficient that at least the same number as the number of hooks are provided at approximately equal intervals in the circumferential direction of the inner and outer band parts 12.16, but in this case, the connecting rubber part 1
It is preferable that the width of the hook 7 is longer than the circumferential length of the hook latching portion 18. In addition, when the number of hook latching portions 18 is greater than the number of hooks, it is preferable to set the width to an integral multiple of the number of hooks within a range that does not make the width of the connecting rubber portion 17 too small.

In the tightening band 10 having the above configuration, the hook of the tire attachment rope of the anti-slip device attached to the tire is attached to the hook hooking portion 18.
When the hook is stopped, the tensile force by the hook is applied to the inner band part 12 via the connecting rubber parts 17 adjacent to the left and right sides of the outer band part 16 at the position where the hook is stopped. Since the elongation of the band portion 12 is suppressed by the reinforcing cord 13, elongation due to the tensile force of the hook occurs in the outer band portion 16 where the hook is not hooked and the connecting rubber portions 17 on both sides thereof. .

Therefore, by setting the circumferential length of the hook holding part 18 and the width of the connecting rubber part 17 to appropriate lengths,
The extension of the outer band portion 16 can be adjusted to an appropriate size.

FIG. 4 is a plan view showing another embodiment of the invention.

In this embodiment, the connecting rubber parts 17 are arranged in three circumferential intervals, large, medium, and small, and the inner band part 12 and the outer band part 16 are connected by connecting the inner band part 12 and the outer band part 16. Stop portion 18a.

Seven pieces each of 18b and 18C are provided at approximately equal intervals in the circumferential direction.

According to the tightening band 10 of this embodiment, the elongation of the outer band portion 16 differs depending on where the hook latching portions 18a, 18b, and 18c are used. 18b, 1.8c
The most appropriate tightening force can be obtained by appropriately selecting one of them.

FIG. 5 is a perspective view showing the state in which the tightening band of the present invention is used.

The hook 22 of the tire mounting lobe 21 of the anti-slip device 20 attached to the tire 30 is hooked to the hook latching portion 18 of the tightening band 10 having a small length in the circumferential direction, and the tire mounting rope 21 is attached. It's making me nervous.

〔Effect of the invention〕

As explained above, in the non-metallic tire skid tightening band of the present invention, the outer band part made of rubber and the inner band part made of a reinforcing cord covered with a rubber layer are concentrically connected by the connecting rubber part. However, a hook latching portion is formed in the space between the outer and inner band portions via a connecting rubber portion. For this reason, even when the tire is running at high speed, centrifugal force causes the outer band to elongate less and the non-slip device spreads less, resulting in damage to the non-slip device and damage to the vehicle body structure due to contact with the vehicle body structure. This reduces the risk and provides a highly reliable tightening band during high-speed running.

Furthermore, according to the present invention, it is possible to suppress the elongation of the tightening band simply by applying a moderately strong tightening force.
An appropriate amount of slippage is ensured between the anti-skid device and the tire, which not only reduces damage to the tire but also significantly improves the durability of the anti-skid device.

Further, according to the present invention, even if the outer diameter of the tightening band is increased, elongation can be suppressed without increasing the tightening force by appropriately setting the dimensions and shapes of the connecting rubber part and the hook latching part. Therefore, a tightening band with good attachment and detachment properties can be obtained.
