Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a tire chain.

[0002]

2. Description of the Related Art A tire chain wound around a tire when traveling on a snowy road is, for example, a ladder-type tire chain in which horizontal chains are connected to each other at predetermined intervals between vertical chains arranged in parallel. , Is used a lot.

[0003]

When such a conventional tire chain is wound around a tire and mounted, it is necessary to lift the tire with a jack or to move the vehicle back and forth. It was very troublesome.

Accordingly, an object of the present invention is to provide a tire chain that can be mounted on a tire with good workability without having to jack up the tire or move the vehicle.

[0005]

In order to achieve the above-mentioned object, a tire chain according to the present invention comprises a ladder-type tire chain, in which a part in the longitudinal direction is divided at one side,
A connection / detachment tool is interposed in the dividing section.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings showing embodiments of the present invention.

FIG. 1 is a plan view of an expanded state of a tire chain showing one embodiment, FIG. 2 is an explanatory view of a connecting operation of a connecting / detaching tool, and FIG. 3 is an explanatory view of an attaching operation of a tire chain.
In these figures, reference numeral 1 denotes a vertical chain and an inner chain.
Consists of 11 and outer chain 12. Reference numeral 2 denotes a horizontal chain, which is connected between the two chains 11 and 12 at a predetermined interval.

The outer chain 12 is divided at its central portion, and a connecting / detaching tool 4 is attached to the dividing portion 3 so that the outer chain 12 can be detachably connected to a link 122 at a corresponding end. A connecting and detaching tool 5 is also attached to one end of the inner chain 11 and the outer chain 12, and the connecting and removing tool 5 can be detachably connected to the links 111 and 121 on the other end.

The connecting and detaching tool 4 (5) is shown in FIGS.
As shown in (D), a long link 41 (51), a locking link 42 (52) movably fitted to the long link 41 (51),
Locking arm 43 (53), and the locking arm 43 (53)
A link hole 431 (531) into which the end of the long link 41 (51) is inserted is formed at the base of the link 122, and the link 122 at the end of the dividing part 3 (or the link 111, 121 at one end). A locking concave portion 432 (532) is formed for locking, and a hook-shaped locking end 433 (533) is formed at a tip portion that curves from the base and extends to a pointed shape. The locking end 433 (533) is locked to the locking link 42 (52) so that a locked state can be formed.

[0010] The connection work of the connecting and detaching tool 4 (5) will be described in detail. First, as shown in FIG. Link
122 (or the links 111 and 121 on the other end side) are fitted, and the connecting / detaching tool 4 (5) is rotated clockwise so that the link 122 (or the links 111 and 121) is moved to the position shown in FIG. As shown in the figure, the locking recess 432 (532) is locked, and the distal end is fitted into the long link 41 (51). When turning the connecting / detaching tool 4 (5) clockwise, the link 122
(Or the links 111 and 121) are pulled in the tightening direction, and the tightening action is exerted.

Next, the locking link 42 (52) is moved to the position shown in FIG.
After moving in the direction of the arrow, the tip of the connecting / detaching tool 4 (5) is rotated counterclockwise, and its locking end 433 (533) is
As shown in FIG. 2D, the locking link 42 (52) is locked. Thereby, the connection operation is completed.

With such a structure in which a part of the outer chain 12 is cut off, there is no need to jack up the tire 6 or move the vehicle, and the tire chain C can be moved to the position shown in FIG.
As shown in (A) to (D), it can be mounted with extremely high workability.

The mounting operation will be described in order. First, as shown in FIG. 3 (A) when the tire chain C is viewed from the bottom, the tire 6 is in a stopped state. The tire chains C are arranged on the ground so as to correspond to the tire tread surface 7 and to the side chains 2 and 2 of the dividing portion 3 on both sides of the tire tread surface 7.

Next, as shown in FIG. 3 (B), the connection / detachment tool 4 of the dividing portion 3 is connected to the link 122 at the corresponding end. FIG. 3 showing the tire 6 viewed from above.
The tire chain C is wound around the tire 6 as shown in FIG. 3C and a side view of FIG.

At this time, each of the horizontal chains 2 is put on the tire 6 at an equal pitch so that the number of inner and outer extra links (portions protruding from the tread portion) is the same. Next, the connection of the connection / detachment tools 5 at one end of the inner chain 11 and the outer chain 12 is connected to the links 111 121 at the other end, respectively, whereby the mounting of the tire chain C is completed.

In the case where the tire contact surface 7 is a soft road surface or a snowy road surface, when the tire chain C is initially laid, for example, as shown in FIG. The horizontal chains 2, 2 of the part 3 may spread outward. However, even in such a state,
The link 122 at the end can be locked in the locking recess 432 of the connecting / detaching tool 4 to complete the connection, and the mounting workability is extremely good.

More specifically, when the width of the tire contact surface 7 is large, when the link 122 at the end is locked in the locking recess 432 of the connecting / detaching tool 4, As shown in FIG. 5, the outer chain 12 has a trapezoidal shape with the bottom as the bottom, leaving an interference 2 d (both interferences d are not always equally distributed).

As described above, the tightening margin 2d is erased by completing the connection of the connecting and detaching tool 4 having a tightening action, and the divided portion 3 is finally brought into a rectangular tension state. . In other words, even if the outer chain 12 is expanded up to the closing margin 2d at the dividing portion 3, the tire chain C
Can be completed.

After the mounting of the tire chain C is completed, for example, as shown in FIG. 6, the outer chain 12 is further tightened by using a tightening band 9 to thereby further tighten the tire chain. You are free to make C even more nervous.

As described above, the tire chain C of the present invention
According to this, the tire 6 to be mounted is jacked up or the (ladder type tire chain C deployed on the ground)
The vehicle does not need to be moved (since the tires are mounted on it), the work is extremely easy, and the work can be performed without soiling the clothes.

It should be noted that the present invention is not limited to the dividing portion 3 of the tire chain C at the center portion, as long as at least a part in the longitudinal direction is divided on one side (outer chain 12). Good.

Further, the material constituting the tire chain may be other synthetic resin material or a combination thereof in addition to metal.

[0023]

According to the first aspect of the present invention, at least a part of the tire chain in the longitudinal direction is divided at one side 12 and the connecting / detaching tool 4 is interposed in the dividing portion 3. The tire 6 does not need to be jacked up and the vehicle does not need to be moved.
Can be attached to
