Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mounting tool for attaching to a tire a tire anti-slip device that is attached to the outer periphery of the tire and prevents the tire from slipping when the vehicle is moving.

[Background Art and Issues to be Solved] A metal chain attached to the outer circumference of a tire is generally used as a vehicle tire anti-slip device used during snowy conditions. However, metal chains are complicated to install, make a lot of noise when the vehicle is running, and have the disadvantage that the chain hits the vehicle body while the vehicle is running, causing damage to the vehicle body.

For this reason, anti-slip devices made of rubber or urethane elastomer have been proposed (Utility Model Publication No. 54-8483), and further anti-slip devices in which rubber is stretched in a net shape to reduce vibrations during driving. There is also.

Such a tire anti-slip device is attached to the tire by wrapping a rubber band around the end of the tire on the outside of the vehicle via a hook. This edge on the outside of the vehicle is in front of the worker when it is installed, making it easy to operate, but the edge in the width direction on the inside of the vehicle on the opposite side is hidden behind the tire, and the worker has to feel around when connecting it. I have to.

In this connection structure, as shown in FIG. 7, a hook 104 is attached to one end of a rope 102 that connects a plurality of widthwise ends of the tire slip IL device body 100 to 11, and this hook 104 is attached to the other end of the rope 102. A hook 108 attached to the loop portion 106 at the other end is hooked to a mounting hole 110 at one longitudinal end of the tire slipping device main body 100.

This type of latching requires some fumbling work on the back side of the tire, and requires attachment at three locations using the hooks 104 and 108, making it a complicated installation process.Furthermore, it is a complicated installation process because the hooks 104 and 108 must be attached at three locations. In addition, friction between the rope 102 connecting the sides of the anti-slip device body and the caulking fitting may cause the rope to become frayed.

The present invention has been made in consideration of the above-mentioned facts, and an object of the present invention is to obtain a mounting tool for a tire slip prevention device that is easy to install.

[Summary and operation of the invention] The present invention is used for attaching a tire slip prevention device to a tire by connecting both ends in the longitudinal direction of a tire slip prevention device body to each other, and is used for attaching a tire slip prevention device to a tire. a second hook that protrudes from the first hook and is latched to one longitudinal end of the main body; and a third hook that protrudes from the first hook and is latched to the other longitudinal end of the main body. It is characterized by having the following.

Therefore, in the present invention, it is only necessary to lock the second hook and third hook protruding from the first hook that is locked to the intermediate portion in the longitudinal direction of the main body to one end in the longitudinal direction of the main body and the other end in the longitudinal direction of the main body, respectively. [Embodiment of the Invention] As shown in FIG. 1, the main body 20 of the tire slip prevention device 10 according to the present embodiment has a continuous net shape in the direction of the arrow 1. It is designed to be wrapped around the outer circumference of a tire (not shown). A plurality of rubber protrusions 22 extend from both ends of the main body 20 in the width direction perpendicular to the arrow direction, and mounting holes 24 are formed in each of these protrusions 22.

As shown in FIG. 2, the protruding portion 22 on one side of the main body 20 is arranged on the inside of the tire 40, that is, on the back side of the tire 40, which is the opposite side from the operator who attaches the tire slip prevention device 10 to the tire 40 during attachment. It is now possible to do so. For this purpose, ropes 36 are attached to these protrusions 22 via hooks 34. This rope 36 is made of a material with little expansion and contraction, and its length is set in advance to a length necessary to attach the tire slip prevention device 10 to the outer periphery of the tire 40, as shown in FIG.

The core material of this rope 36 is urethane and thermoplastic rubber (
It is preferable to use a synthetic m-fiber such as TPR), Tetoron, or nylon to form an elastic ring whose outer periphery is coated with an elastic elastomer such as rubber.This prevents the absorption of moisture from freezing when using conventional braided cords. It is possible to eliminate problems such as hardening and poor biting of metal fittings such as the hook 46 when caulking.

Also, as the braided cord is used, it becomes strained, becomes fluffy, and tends to absorb muddy water, but this can also be resolved.

As shown in FIG. 1, loop portions 50 and 52 are formed at both ends of the rope 36 using caulking metals A38. The loop portion 50 is attached to the hook 34 of the protrusion 22A disposed at the longitudinal end of the tire anti-slip device 10,
The loop portion 52 is arranged near the protruding portion 22B at the other longitudinal end of the tire anti-slip device 2110. The hook 34 is not attached to this protrusion 22B, but the hook 58 of the mounting bracket 54 is caulked.

A hook 56 of a mounting fitting 54 is caulked to the loop portion 52. This mounting bracket 54 has the shape shown in FIGS. 3(A) to 3(D), and is formed by bending a steel wire. That is, one end of the mounting fitting 54 is a hook 56 bent into a loop shape, and the other end is a hook 58 that projects in a direction perpendicular to the hook 56. Further, the middle part is bent into a double tonne to form a hook 6° opposite the hook 56. The folded part forming the hook 60 is wider than the other parts to prevent it from being pulled out. Further, the doubly bent hooks 60 may be fixed to each other by welding or the like.

After the hook 56 is inserted into the loop portion 52, the attachment fitting 54 is caulked and attached to the rope 36.

Further, the hook 58 is caulked to the protrusion 22B, and the hook 6
0 serves as a river to 1 for insertion into the loop portion 50. However, the loop portion 52, without crimping the hooks 56 and 58,
It may also be used by attaching it to the protrusion 22B.

Further, as shown in FIG. 1, a hook 42 is attached to the attachment hole 24 of the protrusion 22 located on the other side of the tire 40, that is, on the outside of the vehicle, when the tire 40 is mounted. These hooks 42 are adapted to hang one key part on the protruding part 22, and to hang the intermediate part of the annular rubber band on the other key part. It is preferable to hook the hook 42 into the attachment hole 24 in advance so that it does not come off.The rubber band may be made of a material other than elastic rubber. multiple protrusions 22
Hooks 46 are hooked to the rubber protrusions 22A and 22B at the ends of the main body 20 in the long hair direction (arrow direction in FIG. 1), so that the rubber protrusions 22A and 22B are continuous. .

The symbol T shown in FIG. 1 indicates the corresponding position of a portion of the tire shoulder when the main body 20 is attached to the tire.

Next, the operation of this embodiment will be explained.

When attaching the tire anti-slip device 2i10 to the tire 40, as shown in FIG. Both ends of the tire anti-slip device 10 may be attached using the metal fittings 54.

In this installation, the hook 60 of the mounting bracket 54 shown in FIG. 1 is inserted into the loop portion 50. In this case, unlike the conventional method, the hook 60 is simply inserted into the loop portion 50, and the operation is easy.

On the front side of some of the tires 40, the hooks 42 may be connected to each other using a rubber band (not shown).

Next, FIGS. 4 and 5 show mounting fittings 66 and 68 used in the second and third embodiments of the present invention, respectively.

These mounting fittings 66 and 68 are both made of thin plate material, and have a circular hole 70 formed at one longitudinal end into which the loop portion 52 of FIG. 1 is inserted, and a hook 60 at the other end. The hook 60 of the mounting bracket 66 is formed by bending the end of the plate into a U-shape, and the hook 60 of the mounting bracket 68 is formed by cutting and bending a part of the plate.

Further, an extension part protrudes from the middle part of the plate material in a perpendicular direction, and a hook 58 is formed in this extension part. In the mounting bracket 66, the hook 58 is formed by bending a plate material into a loop shape, and in the mounting bracket 68, the hook 58 is formed by cutting and bending similarly to the hook 60.

Therefore, these fittings 66 and 68 can also facilitate the connection of both lengthwise ends of the tire anti-slip device 10, similarly to the fittings 54 of the first embodiment.

FIG. 6 shows a fourth embodiment of the invention. In this embodiment, a mounting bracket 80 is used in addition to the mounting bracket 66. This fitting JJ80 has a caulking portion 82 formed at one end thereof, into which the loop portion 50 of the rope 36 is caulked, and a long hole 84, into which the hook 60 of the attachment fitting 66 is latched, at the other end.

Therefore, the loop part 50 and the hook 60 as in the above embodiment
The loop part 50 will not be rubbed due to the latching.

Note that the hook 56 and the circular hole 70 in each of the above embodiments may be directly attached to an appropriate position such as the middle part of the tire slip prevention device 10 without using the loop portion 52 of the rope 36. .66.68 can be applied not only to the inside of the tire but also to the outside of the vehicle when installing a tire anti-slip device.

[Effects of the Invention] As explained above, the present invention is used for attaching a tire skid prevention device to a tire by connecting both longitudinal ends of the tire skid prevention device body to each other, and is used for attaching the tire skid prevention device to the tire by connecting the longitudinal ends of the tire skid prevention device body to each other. a second hook that protrudes from the first hook and is locked to one longitudinal end of the main body; and a second hook that projects from the first hook and is locked to the other longitudinal end of the main body.
