Abstract

(57) [Summary] (with amendments) [Purpose] To securely bridge cross cables at regular intervals between two side cables via side metal fittings having joints with uneven surfaces formed on the inner surface. [Structure] When multiple cross cables are bridged between two parallel side cables at fixed intervals via side metal fittings, a large number of wires are connected to the cross cable side connecting portion of the side metal fittings. An uneven surface having a shape, a mesh shape, or an irregular shape is formed, and the end portion of the cross cable is crushed and caulked using the uneven surface as an inner surface. As a result, the protruding portions of the uneven surface bite into the space between the strands of the cross cable, significantly increasing the frictional force between them, thereby making the connection stronger and improving durability.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a cable-type tire anti-slip device for automobiles used when driving on icy and snowy roads. The purpose is to improve the durability of anti-slip devices.

0002

[Conventional technology]

As shown in Fig. 8, the conventionally known cable type tire slip prevention device Outer side wire a that runs along the side tread surface and the inner tread of the tire. Two parallel side cables are created by the inner side wire b that runs along the board surface. A spring d, a collar e, etc. wound in a coil at regular intervals are placed between the bulls. Fold back the inserted cross cable c at both ends to create a crushed part. Attach them orthogonally through the side fittings f, and then attach the tires at both ends. Attach a plate hook g and a hook h to the end of the cut corresponding to the inner circumferential side. Attach an S-shaped plate hook i to one side of the cut end corresponding to the outer circumference of the ear. A corresponding C-shaped link j is installed on the opposite side of the link. .

[Problem that the idea aims to solve]

However, in the conventional cable type tire slip prevention device mentioned above, The connection between the cross cable side connection part of the loss fitting and both ends of the cross cable is simply Since this is done by crushing and caulking the joints, the amount of caulking is insufficient. If the cross cable is connected to the cross bracket, it will be relatively easy to pull out from the cross If the amount of wire is excessive, crush and cut the bare wires of the cross cable, or There were problems such as inhibiting durability against repeated loads.

0004 Therefore, in this case, it is necessary to maintain and manage the amount of caulking by the cross metal fittings optimally. was extremely difficult and required a lot of experience.

[0005]

[Means to solve the problem] Therefore, in the present invention, we have solved the various problems in the prior art described above. In addition to improving the durability of various types of anti-slip devices, it also reduces the This eliminates the need for extensive experience, and specifically requires two parallel side cables. In between, multiple cross cables are strung at regular intervals via side metal fittings. In the ladder-type tire anti-slip device, the above-mentioned side bracket cross The cable side joint has many linear, mesh, or irregularly shaped surfaces. At the same time, the uneven surface is used as the inner surface and the end of the cross cable is crushed and caulked. This invention relates to a cable type tire slip prevention device characterized by:

[0006]

[Effect]

Forming uneven surfaces such as many linear, mesh-like, or irregular shapes on side metal fittings. Insert the cross cable into the cross cable side joining part formed by the cross cable with the uneven surface inside. If you wrap it around the end and then crush and swage it, the protruding part of the uneven surface mentioned above will be crimped. It bites between the wires of the loss cable and significantly increases the frictional force between them. This will unite the two together and more firmly.

[0007]

【Example】

The specific contents of the present invention will be explained below based on the first embodiment shown in FIGS. 1 to 4. Then, 1 represents a cross cable, 2 represents a side cable, and 3 represents a side metal fitting. The side metal fittings 3 are made by processing a flat metal plate to connect the cross cable side joint 3a and the support. A side cable side coupling portion 3b is formed. Side cable side joint part 3b The tip is folded back and connected to the side cable 2, and the clip The loss cable side joint portion 3a is curved to cover the end of the cross cable 1. It is formed with a cross cable on its inner surface as shown in Figures 3 and 4. A large number of linear uneven surfaces are formed in a direction perpendicular to the length direction of 1. Ru.

[0008] Also shown in FIG. 5 is a second embodiment of the present invention, in which the cross case is On the inner surface of the bull side coupling part 3a, there are many A linear uneven surface is formed. Further, FIG. 6 shows a third embodiment of the present invention. In this case, the cross cable 1 is attached to the inner surface of the cross cable side coupling part 3a. A large number of linear uneven surfaces are formed that are inclined at a certain angle with respect to the length direction. .

[0009] Furthermore, FIG. 7 shows a fourth embodiment of the present invention, in which the cross A mesh-like uneven surface is formed on the inner surface of the cable side joint portion 3a. Other black Regarding the shape of the unevenness formed on the uneven surface of the connecting part on the cable side, It is not limited to the examples, but also includes irregular shapes such as irregular uneven shapes. It will be done. The formation of these various uneven surfaces can be done, for example, by knurling process or It can be easily shaped by coining or embossing.

[Effect of the idea]

As mentioned above, this invention has a large number of wires at the cross cable side connection part of the side metal fitting. It has an uneven surface in the shape of a shape, a mesh shape, or an irregular shape, and the uneven surface is formed on the inner surface. Because the cross cable ends are crushed and caulked, the protrusion of the uneven surface is prevented. The part that has been cut into the wires of the cross cable will bite into the wires, significantly increasing the frictional force between them. This allows the two to be integrated and more firmly connected, making this type of cable type connector As an anti-slip device, it is durable enough to withstand repeated loads from harsh use. can be significantly improved.
