Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a tire chain that can be easily attached to and detached from a tire.

0002

[Conventional technology]

Traditionally, spikes have been used to ensure safe driving on icy and snowy roads. Spiked tires with spikes (also called do) were widely used. Once installed on a car, these spiked tires cannot be used continuously during the winter. To prevent this, frequently drive on roads where the snow and ice have melted and the road surface is exposed (dry road surface). Sometimes, the tips of the spikes scrape the road surface. Scrape it like this The collected dust flies up into the atmosphere and causes air pollution, and the dust is harmful to the human body. is also harmful. Due to this situation, people have begun to refrain from using spiked tires. , the tire chains have been revisited.

0003

[Problem that the idea aims to solve]

However, tire chains are difficult and time-consuming to attach to cars. This is a work that requires a lot of effort. It is also tough work outdoors in the cold winter. Therefore, the present invention aims to provide a tire chain that is easy to attach to tires. purpose.

0004

[Means to solve the problem]

In order to solve the above problems, the present invention has the following configuration. i.e. parallel side chains that run along the inside and outside of the tire circumference. In anti-slip tire chains with horizontally connected chains, Along the side chain placed inside, it has flexibility and straightness. A guide member is attached, and both ends of the guide member can be connected. Ru. In addition, the connecting means of the guide member is such that an insertion bar is provided at one end, and an insertion bar is inserted at the other end. It is also possible to provide a hollow portion for the insertion.

[0005]

[Effect]

Next, the effect will be explained. Place the chain body along with the guide member on the back side of the car tire, and Pull both ends of the tire towards you from above the tire, insert the insertion bar into the hollow part and guide it. Both ends of the member are connected, and both ends of the inner side chain are connected. Furthermore, the guide member and the connecting part of the inner side chain are attached to the bottom edge of the tire. Hold the guide member and rotate the chain 180 degrees so that the Make sure to cover the upper circumferential surface of the ear. Pull both ends of the outer side chain located at the lower end toward the front of the tire, and then Connect the ends and the installation is complete.

【Example】

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 shows a plan view of a tire chain according to the present invention. The tire chain 10 according to the present invention includes a chain body 12 formed in a ladder shape and , and a guide member 20 attached to this chain body 12.

[0007] The chain body 12 consists of two chains, similar to a conventionally known tire chain. A connecting chain that connects parallel side chains 12a and 12b at predetermined intervals. 14... is suspended horizontally. Moreover, at one end of the side chains 12a and 12b, , a locking hook 16 and a locking ring 18 are provided.

[0008] The guide member 20 is made of a spirally wound spring material and has flexibility as well as linearity. (a certain degree of rigidity), and this guide material 22 The insert bar 24 is fixed to one end 22a of the insert bar 24. This insertion bar 2 4 is formed in an arc shape and can be inserted from the hollow part of the other end 22b of the guide member 22. When the insertion bar 24 is inserted from the hollow part of the other end 22b of the guide member 22, the guide member 2 0 is entirely ring-shaped. The guide member 20 is fixed to both ends of the inner side chain 12b of the chain body 12. The middle part is guided along the inner side chain 12b by the guide ring 24... It is held in such a way that it

[0009] Regarding the method of attaching the tire chain 10 configured as described above to a tire explain. A tire check is placed on the back side of a car tire 30 using the guide member 20 as a guide. 10 (see Figure 2). The guide member 20 has flexibility and linearity (a certain degree of rigidity). (because it can maintain its shape as a bar), push it from the insertion side on the back side of the tire 30 to the opposite side. Then, the tire chain 10 can be placed. Next, pull out both ends of the guide member 20 from above the tire 30 to the front side (Fig. 2). Then, insert the insertion bar 24 from the hollow part of the other end 22b of the guide member 22. (temporarily fastened with the guide member 20), and the inner side chain 12 The locking hook 16 at one end of b, the locking ring 18, and the other end of the inner side chain 12b. Link. In this state, the guide member 20 is formed into a ring shape. Then, the connecting portion of the guide member 20 and the inner side chain 12b is tied. Hold the guide member 20 and rotate it 180 degrees so that it is located at the lower end of the wheel 30. At this time, the chain body 12 is placed over the circumferential surface of the tire 30. The locking hook 16 and the locking ring 18 of the outer side chain 12a located at the lower end The tire 30 is pulled out to the front side and both ends are connected to complete the installation.

0010 On the other hand, when removing the tire chain 10, tap the connecting part of the tire chain 10. the locking hooks of the side chains 12a, 12b. The connection between the hook 16 and the retaining ring 18 is released. Then, the guide member 20 maintains the linearity. As a result, the insertion bar 24 is no longer inserted into the hollow part, and extends linearly and spreads. . Therefore, the tire chain 10 does not get tangled around the axle of the tire 30, making it easy to It can be removed.

[0011] Note that the guide member may be a simple wire or a tube made of synthetic resin, and has flexibility. It may be any material as long as it has linearity (a certain degree of rigidity). Also, The connecting means of the guide tab member 20 does not have to be an insertion/removal means and can be modified in various ways. Ru. Although various explanations have been given above using preferred embodiments of the present invention, the present invention is limited to the above embodiments. It is not a fixed value, and many modifications can be made without departing from the spirit of the invention. Of course.

[Effect of the idea]

The present invention is constructed as described above, and has the following effects. (1) Flexible and straight along the inner side chain of the chain body. Since the linear guide member is provided, hold one end of the guide member and attach it to the tire chain. The tube can be easily passed through the back of the tire. (2) Also, when both ends of the guide member are connected, the guide member becomes ring-shaped, and the inner Both ends of the side chain can be easily connected by locking hooks. (3) On the other hand, when the tire chain is uncoupled at both ends, the guide member is straight Since the chain spreads out in a shape, the tire chain does not get tangled with the axle or the like. (4) A guide member is provided along the chain body, so it can be removed during use. It can be used immediately without the chain body getting tangled. (5) If both ends of the guide member are connected by inserting an insertion bar into the hollow part, , it can also be used for chain bodies that differ to some extent in length.
