Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a tire anti-slip device, and more particularly to a tire anti-slip device that can be more reliably and easily attached to and removed from a tire.

(Prior Art) Conventionally, a tire slip prevention device has a structure in which, for example, a connecting chain is disposed at intervals between an inner chain and an outer chain, and the ends of each chain can be engaged with each other. A locking chain is provided at one end of the inner chain, and a through ring for holding the locking chain is provided at the other end of the inner chain and the opposite end of the outer chain. established,
A structure in which the locking chain is inserted through the loop and its front end is engaged with one end of the outer chain is known and used.

In addition, devices with various other configurations are known (for example, see Japanese Utility Model Publication No. 58-55051). However, all of these devices have the same basic structure as the tire anti-slip device of the above-mentioned configuration. The configuration is the same.

(Problems to be Solved by the Invention) Conventionally known tire anti-slip devices have the configurations described above, but these have the following problems.

The conventional model has the problem that the length of the inner chain and the outer chain are almost the same, and it is difficult to attach and detach the inner chain because it is necessary to grope or hide under the vehicle body. be.

Also, unlike the conventional example, the locking chain extends from one end of the inner chain, making it easy to attach and remove the tire, but there is a problem that it tends to come off while driving. .

Further, tire anti-skid devices having other configurations cannot completely solve the above problems.

The present invention was developed in response to the above-mentioned problems, and its purpose is to solve the problems of conventional tire anti-slip devices, namely, to make it easier to attach and detach them from the tire. To provide a tire anti-slip device that is easily made, can be reliably attached to and removed from a tire, and is less likely to come off during driving.

(Means for Solving the Problems) The anti-skid device of the present invention as a means for achieving the above object includes a connecting chain arranged at intervals between an inner chain and an outer chain. In the tire anti-slip device, a locking wire having locking devices at both ends is inserted and inserted into one end of the inner chain via a support ring, and
A locking device is provided at one end of the outer chain facing the inner chain, and the other ends of the inner chain and the outer chain, and a locking device is provided at the other end of the inner chain and the outer chain. A holder made of a through ring or the like for inserting and holding the locking wire in the direction of the outer chain from the inner chain is provided at each part of both chains near the tool, and the locking wire is The locking tool at one end is locked with the locking tool at the other end of the inner chain, and the locking tool at the other end of the locking wire is connected to the outer chain via the holding part. It consists of a structure that allows it to be stopped.

Here, the support ring is a ring that fits and supports the locking wire and allows arbitrary movement of the locking wire, and is formed of a normal ring.
In some cases, it is formed by a ring at the end of the chain.

As the locking wire, a chain having a length equal to or slightly longer than the connecting chain, a flexible plate-like material, or a cylindrical material is generally used. This is to improve the anti-slip effect of the chain. Note that the term "locking wire" as used herein is a concept that includes strings such as ropes. Note that a rope or other string may be attached to one end of the locking wire. In this case, handling becomes easier.

Further, as the holding portion, a through ring or a pressing member having an anti-slip function and suspended between the inner chain and the outer chain is used. However, the holding portion is not limited to this, and may have other configurations.

Furthermore, although the locking device is usually formed of a hook or a ring that engages with the hook, other configurations may also be used.

In addition, here, ``Inside'' in ``A locking device is provided at the other end of the inner chain and the outer chain, and on the inside...'' refers to ``the inner chain and the outer chain in the direction of one end when viewed from the other end.''"location". Furthermore, the chains constituting the inner chain and outer chain are not only chains but also include strings such as wires or ropes. Thus, for example, it may be designed as an inner wire and an outer wire.

(Operation) Next, the operation of the present invention will be explained based on the above configuration.

First, after covering the tire with a tire anti-slip device,
a stop formed on the other end of the inner chain;
By engaging with the locking tool formed at the end of the locking wire disposed at one end, that is, by moving the locking wire to the one end side via the support ring. The maximum length serves to facilitate engagement with the locking device formed at the other end of the inner chain.

Next, when the other end of the locking wire is pulled, the inner chain is tightened, and the locking wire is further pulled and locked to the outer chain through the holding part, and both ends of the outer chain are tightened. The engagement allows the tire anti-skid device to be attached to the tire.

Next, in order to remove the tire anti-skid device from the tire, after releasing the engagement between the locking tool formed at the end of the locking wire and the outer chain,
If the locking wire falls off, stop the vehicle so that it does not get entangled with the vehicle's axle, or attach the locking tool formed at the end of the locking wire to the outer chain side end of the holding part or the The device works so that the tire anti-slip device can be removed by locking it nearby, peeling off the inner chain and dropping it on the outside of the tire, and then driving the car forward or backward again, or by lifting the car body with jacks, etc. .

In the case of this configuration, the inner chain can be removed, which was difficult in the conventional tire slip prevention device attachment/detachment work, by simply loosening the tightened locking wire (string, etc.).

(Example) Next, the present invention will be described in more detail based on the example shown in the drawings.

Embodiment 1 In this embodiment, as shown in FIG. 1, a plurality of connecting chains 12 are arranged at intervals between an inner chain 10 and an outer chain 11, and a support ring is provided at one end of the inner chain 10. 13 is formed.

Here, the support ring 13 is formed of a pulley (a ring with a guide groove on the outer circumferential surface), and the support ring 13 has a locking wire 16 having locking tools 14 and 15 at both ends. is inserted and arranged. The locking wire 16 can be moved freely in the direction of the locking tools 14 and 15 via the support ring 13. That is, when the locking wire 16 is prevented from moving, its length becomes longer. Further, the locking wire 16 may be partially provided with a chain having the same length as the connecting chain or a little longer than the connecting chain.

Furthermore, a locking tool 17 is provided at one end of the outer chain 11 facing the inner chain 10.

Furthermore, locking devices 18 and 19 are provided at the other ends of the inner chain 10 and the outer chain 11, respectively. A holding portion 20 for holding the locking wire 16 is disposed inside thereof.

Here, the holding portion 20 is formed by a through ring 21. The through rings 20 are usually disposed on the inner chain 10 and the outer chain 11 so as to be perpendicular to the tire to be attached (see FIG. 2). For example, a direction changing member such as an S-shaped member is used so that the through ring 20 portion is always perpendicular to the tire to be attached.

In this configuration, the locking wire 16 is
It becomes possible to facilitate the insertion of the

Further, in order to facilitate the insertion of the locking wire 16 during attachment and detachment, the loop 20 is preferably shaped so that the chains on both sides are not located inside, as shown in FIG. 3.

Next, the operation of this configuration will be explained.

In FIG. 1, first, when the tire is covered with a tire anti-slip device, one of the locking tool 18 formed at the other end of the inner chain 10 and the locking wire 16 disposed at one end. By engaging the locking tool 14 formed at the end of the inner chain 16, that is, by moving the locking wire 16 to one end thereof via the support ring 13, the inner chain 16 is set to the maximum length. It acts to facilitate engagement with the locking tool 18 formed at the other end.

Next, when the other end of the locking wire 16 (locking device 15 side) is pulled, the inner chain 10 and the locking wire 16 are tightened, and then the inner chain 10 and the locking wire 16 are tightened. By locking onto the chain 11 and engaging both ends 17 and 19 of the outer chain 11, the tire anti-skid device can be attached to the tire. Note that the engagement of the locking portions 17 and 19 is controlled by the locking portions 14 and 18.
A similar effect occurs even after the engagement of .

Next, in order to remove the tire anti-skid device from the tire, after releasing the engagement between the locking device 15 formed at the end of the locking wire 16 and the outer chain 11, the locking wire 16 Stop the car so that it does not get entangled with the axle of the car even if it falls off, or attach the locking tool 15 formed at the end of the locking wire 16 to the end of the outer chain 11 side of the holding part 20 or the end of the locking wire 16. The tire anti-slip device can be removed by locking it nearby, peeling off the inner chain 10 and placing it on the outside of the tire, and then driving the car forward or backward again, or by lifting the car body with a jack or the like. do.

In the case of this configuration, the inner chain 10 can be removed, which was difficult in the conventional tire slip prevention device attachment/detachment work, by simply loosening the tightened locking wire 16 (string, etc.). do.

Example 2 In this example, as shown in FIG. 4, in Example 1, the holding part 20 is formed by a holding member 22 having an anti-slip function and suspended between the inner chain 10 and the outer chain 11. . here,
The holding member 22 has a recessed portion in its bottom portion so that the locking wire 16 can be just accommodated so that the locking wire and the like will not protrude due to the centrifugal force of the tire during installation.

Furthermore, one end of the holding member 22 (particularly on the outer chain side) may not be fixed to the chain 10 or 11, but may be detachable.

In this embodiment, the locking wire 1
6 wear and tear can be reduced.

Embodiment 3 As shown in FIG. 5, in this embodiment, a part of the locking wire 16 in Embodiment 1 is provided with a flexible plate or cylinder having the same length as the connecting chain or slightly longer. It consists of a structure in which a body 23 is arranged.

It should be noted that the present invention is not limited to the embodiments described above, and may be modified without changing the gist of the embodiments. Incidentally, a configuration as shown in FIG. 6 may be used. That is, in the first embodiment, a locking wire (chain) having a locking tool at each end is provided at both ends of the inner chain 10. In this configuration, each locking wire can be attached to and detached from the tire by being held by a holding portion located at the other end.

Here, the holding portion may be formed at a position slightly inside the end of the inner chain.

(Effect of the invention) As is clear from the above explanation, the present invention provides a tire skid device in which a connecting chain is disposed at intervals between an inner chain and an outer chain, in which a support ring is attached to one end of the inner chain. A locking wire with locking tools at both ends is inserted and inserted through the chain, and the chain can be attached using the locking wire, so it can be easily attached to and detached from the tire. This has the effect of providing a tire anti-slip device that can be reliably attached to and removed from a tire and is less likely to come off while driving.
