Description

Description: TECHNICAL FIELD The present invention relates to a tire anti-slip device mounted on the outer periphery of a tire to prevent the tire from slipping when the vehicle is traveling.

[Background Art and Items to be Solved] As a vehicle tire anti-slip device used at the time of snowfall or the like, a metal chain mounted around the tire is generally used. However, the metal chain is disadvantageous in that the mounting is complicated, the noise during running is large, and the chain hits the vehicle body and damages the vehicle body during traveling.

For this reason, a non-slip device made of rubber, urethane elastomer, or the like has been proposed (Japanese Utility Model Publication No. 54-8483). Further, there is also a tire anti-slip device in which rubber is stretched in a net shape in order to reduce the vibration during running.

In such a tire anti-slip device, a rubber band is wound around an end of the tire on the vehicle outside via a hook, and the tire is attached to the tire. The outer end of the vehicle is easy to operate because it is in front of the worker at the time of mounting,
The opposite widthwise end inside the vehicle is hidden behind the tires, and the operator must grope for the connection.

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 portions at the widthwise ends of the tire antiskid device main body 100 to each other.
The hook 108 attached to the other end loop portion 106 of the rope 102 is hooked to a mounting hole 110 at one longitudinal end of the tire slip prevention device main body 100.

Such latching is a groping operation on the back side of the tire, and requires two mountings by hooks 104 and 108, which is a complicated mounting operation. Further, a force is applied to the hook 108 during traveling, and the hook is rubbed between the rope 102 connecting the side surfaces of the anti-slip device main body to each other and the caulking fitting, thereby causing the rope to be fluffy.

The present invention has been made in view of the above circumstances, and has as its object to provide a tire anti-slip device that can be easily mounted.

[Summary and Action of the Invention] A tire anti-skid device of the present invention includes a tire anti-slip body disposed on an outer peripheral surface of a tire, and a width direction of the tire anti-slip body disposed along a longitudinal direction of the tire anti-slip body. An elongate body connecting a plurality of end portions to each other, a first hook engaged with the main body, and a second hook protruding from the first hook and engaged with one longitudinal end of the elongate body. And a third hook protruding from the first hook and locked to the other longitudinal end of the elongated body. Therefore, in the present invention, if the second hook is locked to one end of the elongated body in advance, the third hook protruding from the first hook locked to the main body is locked to the other end of the elongated body. It can be easily installed.

[Embodiment of the Invention] As shown in Fig. 1, the main body 20 of the tire anti-slip device 10 according to the present embodiment is formed so that a net shape is continuously formed in the direction of arrow D, and is wound around the outer periphery of the tire (not shown). It has become. Further, a plurality of rubber protrusions 22 are extended at both ends in the width direction of the main body 20 in a direction perpendicular to the direction of arrow D, and mounting holes 24 are formed in these protrusions 22, respectively.

As shown in FIG. 2, the protruding portion 22 on one side of the main body 20 is located on the inside of the tire 40, that is, the tire 40 on the opposite side to the worker who mounts the tire anti-slip device 10 on the tire 40 at the time of mounting.
Is arranged on the back side of the camera. For this purpose, a rope 36 is attached to these projections 22 via a hook 34. The rope 36 is made of a material with little expansion and contraction, and has a length necessary for mounting the tire anti-slip device 10 on the outer periphery of the tire 40 in advance as shown in FIG.

The rope 36 preferably has a structure in which a synthetic fiber such as urethane, thermoplastic rubber (TPR), tetron, or nylon is used as a core material, and an elastic ring whose outer periphery is coated with an elastic elastomer such as rubber is used. As a result, when the braid is used as in the related art, it becomes hard due to the freezing of the absorbed moisture,
It is possible to eliminate a poor biting at the time of caulking metal fittings. In addition, the use of the braid causes rubbing and fluffing, and muddy water is easily absorbed, but this can be solved.

As shown in FIG. 1, loop portions 50 and 52 are formed at both ends of the rope 36 by caulking fittings 38, respectively. The loop portion 50 is attached to the hook 34 of the protruding portion 22A disposed at the longitudinal end of the tire anti-skid device 10, and the loop portion 52 is formed on the protruding portion 22B at the other longitudinal end of the tire anti-skid device 10.
It is located near. The hook 34 is not attached to the protrusion 22B, and the hook 58 of the mounting bracket 54 is swaged.

A hook 56 of a mounting bracket 54 is swaged to the loop portion 52. The mounting bracket 54 has a shape shown in FIGS. 3A to 3D, and is formed by bending a steel wire. That is, one end of the mounting bracket 54 is a hook bent in a loop shape.
The other end is a hook 58 protruding in a direction perpendicular to the hook 56. In addition, the middle portion is bent twice to form a hook 60 facing the hook 56. The folded portion forming the hook 60 is wider than the other portions and is used for retaining. The double bent hooks 60 may be fixed to each other by welding or the like.

The mounting bracket 54 is caulked after the hook 56 is inserted into the loop portion 52, and is mounted on the rope 36. The hook 58 is swaged to the protruding portion 22B, and the hook 60 is
It is for insertion hooking to 0. However, the hooks 56 and 58 may be hooked onto the loop portion 52 and the protruding portion 22B without being swaged.

As shown in FIG. 1, a hook 42 is attached to the other side of the tire 40 at the time of mounting, that is, to the mounting hole 24 of the protruding portion 22 arranged on the outside of the vehicle. These hooks
Reference numeral 42 locks one key portion to the protruding portion 22 and locks an intermediate portion of the annular rubber band to the other key portion. It is preferable to hook the hook 42 in advance so as not to come off the mounting hole 24. As the rubber band, a material other than elastic rubber can be used. Hooks 46 are hooked on rubber protrusions 22A and 22B at the ends of the main body 20 in the longitudinal direction (the direction of arrow D in FIG. 1) of the plurality of protrusions 22, and the rubber protrusions 22A and 22B are hooked.
Is to be continuous.

Reference symbol T shown in FIG. 1 indicates a corresponding position of the tire shoulder portion when the main body 20 is mounted on a tire.

 Next, the operation of the present embodiment will be described.

When the anti-skid device 10 is mounted on the tire 40, as shown in FIG.
One side in the width direction of the tire anti-slip device 10 may be arranged on the axle side where the 40 is mounted, and both ends of the tire anti-slip device 10 may be mounted using the mounting bracket 54.

In this mounting, the mounting bracket 54 shown in FIG.
Then, the hook 60 is inserted into the loop portion 50. In this case, unlike the conventional case, only the hook 60 is inserted into the loop portion 50, and the operation is easy.

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

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

Each of these mounting brackets 66 and 68 is formed of a thin plate material, and has a circular hole 70 at one end in the longitudinal direction through which the loop portion 52 of FIG. 1 is inserted, and a hook 60 at the other end. In the mounting bracket 66, the hook 60 is formed by bending a plate end into a U-shape, and in the mounting bracket 68, the hook 60 is formed by cutting and raising a part of the plate material.

In addition, the extension part projects perpendicularly from the middle part of the plate,
A hook 58 is formed here. The hook 58 is formed by bending the plate material into a loop in the mounting bracket 66, and the hook 58 is formed by cutting and raising the mounting bracket 68 in the same manner as the hook 60.

Therefore, these mounting brackets 66 and 68 can also easily connect both ends of the tire anti-slip device 10 in the longitudinal direction, similarly to the mounting bracket 54 of the first embodiment.

FIG. 6 shows a fourth embodiment of the present invention. In this embodiment, a mounting bracket 80 is used in addition to the mounting bracket 66. The mounting bracket 80 has a caulking portion 82 at one end where the loop portion 50 of the rope 36 is swaged, and an elongated hole 84 at the other end where the hook 60 of the mounting bracket 66 is hooked.

For this reason, there is no rubbing of the loop portion 50 due to the hook between the loop portion 50 and the hook 60 as in the above embodiment.

The hook 56 and the circular hole 70 in each of the above embodiments are ropes.
The tire anti-slip device 10 does not need to go through the loop portion 52 of 36.
May be directly attached to an appropriate position such as an intermediate portion. These mounting brackets 54, 66, 68 can be applied not only to the inside of the tire but also to the case where the anti-skid device is installed outside the tire.
