Abstract

(57) [Summary] (with amendments) [Purpose] Using a side metal fitting with left and right folded parts formed between two side cables through a cut groove in the middle part in the width direction, the left and right folded parts are By caulking the side cables, the cross cables are strung at regular intervals to make it stronger. [Structure] When multiple cross cables are bridged between two parallel side cables at fixed intervals via side metal fittings, the side cable side joining part of the side metal fittings mentioned above is connected in the width direction. Through the cut groove in the middle part,
A pair of left and right folded parts are formed, and the respective folded axes of the folded parts are oriented in the axial direction of the side cable to be tensioned in an annular shape, and the left and right folded parts are crushed and caulked to the side cable. This increases the coupling force of the cross cable to the side cable and improves the durability of the anti-slip device.

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 Figure 4, 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 side cable side connection part of the loss fitting and the side cable is simply folded back. The amount of crimping is insufficient because it is done by crushing and crimping. Because the side metal fittings may slip against the side cables, The mounting position often moved, which caused problems in terms of durability.

0004 On the other hand, if the amount of caulking is excessive, it may crush the side cable wires. There were problems such as cutting or inhibiting durability against repeated loads. 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 slip prevention device, the side bracket of the side metal fittings described above is The cable side joint part has a pair of left and right folded parts through a cut groove in the middle part in the width direction. At the same time, the respective folded axes of the folded portions are tensioned in an annular shape. Hold the left and right folded portions of the side cable in the axial direction of the side cable. A cable-type tire slip prevention device featuring a crushing caulk attached to a bull. related.

[0006]

[Effect]

A pair of left and right grooves are formed in the side cable side connection part of the side metal fitting. Attach the folded portions to the side cables that are tensioned in an annular shape by crushing and caulking them. When an ear anti-slip device is configured, the bonding strength is doubled, and In particular, the respective axes of the left and right folded portions are in different directions, that is, in an annular shape. The cross cable is oriented in the axial direction of the side cable, which is tensioned in When the cross cable receives the driving torque, the driving torque is applied to the cross cable. is applied to the side cable due to repeated bending. This can greatly improve the durability of the device.

[0007]

【Example】

The specific content of the present invention will be explained below based on the embodiments shown in FIGS. 1 to 3. , 1 represents a cross cable, 2 represents a side cable, and 3 represents a side metal fitting. sa The side metal fitting 3 is made by processing a flat metal plate to connect the cross cable side joint part 3a and the side A cable side joint portion 3e is formed. The cross cable side joint part 3a is It is curved to cover the end of the loss cable 1, and is Accordingly, a large number of linear or mesh-like uneven surfaces are formed on the inner surface.

[0008] In addition, the side cable side joint portion 3e has a cut groove 3b in the middle portion in the width direction. Fold back the left and right plates to form the folded part 3c. and 3d respectively, and , the folding axis A-A of the folding part 3c, and the folding axis B- of the folding part 3d. B and B are oriented in different directions, and their respective folding axes are tensioned in an annular shape. The side cable 2 is configured to face in the axial direction of the side cable 2.

[0009] Using the above side metal fitting 3, connect the cross cable to the cross cable side joint 3a. At the same time, the end of the cable 1 is crushed and caulked, and the side cable side joint part 3e is folded. part 3c. After inserting the side cable 2 inside 3d, crush it. It is caulked to form an anti-slip device.

[Effect of the idea]

As mentioned above, this invention uses a side metal fitting between two parallel side cables. A ladder-shaped tie constructed by spanning multiple cross cables at regular intervals. In the anti-slip device, the side cable side connection part of the side metal fitting mentioned above is A pair of left and right folded parts are formed through a cut groove in the middle part in the width direction. This is because the left and right folded parts are used to crush and caulk the side cables. , the bonding strength is doubled.

[0011] In particular, the above-mentioned pair of left and right folds formed at the side cable side joining part of the side metal fittings. The respective folding axes in the folding part are set in different directions, that is, circularly. Because the side cable is oriented in the axial direction where it is tensioned, the cross cable is Even if the cable receives a drive torque, the drive torque is not generated in the cross cable. to reduce the excessive force exerted on the side cables due to repeated bending. This can greatly improve the durability of the device.
