Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tire anti-skid device for traveling on a snowy road or an ice road.

[0002]

[Prior Art]

 As shown in Fig. 6, a non-metallic non-skid tire anti-skid (chain) that has been conventionally used has a ladder-like shape as a whole, and has tightening ropes 11 on both sides and a plurality of ropes between them. The anti-slip plates 14 are attached at substantially equal intervals. The outer rope 11a of this chain has a split connection portion 12, and as will be described later, the end connection fitting 13 and the connection portion 12 are connected to each other for attachment to the tire.

By the way, although this chain has a front side and a back side whose ground side is determined, two chains with the same attachment position of the connecting portion 12 are prepared, and there is no distinction between the right side and the left side. It is a thing. Therefore, in order to attach this chain to the tire, it must be arranged on the tire as shown in FIG. 6, and as shown in FIGS. 4 and 5, once in the front and once in the rear, a total of 2 It is necessary to move the vehicle once.

First, when the chain is attached to the tire on the left side of the vehicle, the grounding surface of the chain 15 is faced up, and the side where the disconnection connecting portion 12 is located (outer rope 11a) is arranged so as to face the left side of the vehicle. Put the chain 15 on the cover (Fig. 4 (A)). Connect the end connecting fittings 13 at both ends of the inner rope 11b, and move the vehicle backward (rotate the tire in the direction of the arrow) so that the chain 15 passes between the ground and the tire (Fig. 4 (B)). , Connect the end connection fittings 13 at both ends of the outer rope 11a to each other and attach them.

Next, when the tire chain is mounted on the right side of the vehicle, the grounding surface of the chain 15 is faced up, and the side with the disconnection connecting portion 12 (outer rope 11a) is different from that on the left side. Place it so that it faces the right side, and put the chain on the tire (Fig. 5 (A)). Connect the end connection fittings 13 at both ends of the inner rope 11b, and move the vehicle forward (rotate the tire in the direction of the arrow) so that the chain 15 passes between the ground and the tire (Fig. 5 (B)). ), Connect the end connection fittings 13 on both ends of the outer rope, and complete the installation. In this way, when there is no distinction between right and left, it was necessary to move the vehicle twice, forward and backward.

[0006]

[Problems to be solved by the device]

 However, in the above-mentioned conventional example, it is necessary to move the vehicle twice when attaching the chain, which is very troublesome. If the size of the vehicle is small, it is not a big problem, but if it is large like a truck or a bus, the distance between the driver's seat and the tires is long, which is extremely inconvenient for the user. There is no problem as described above if you raise the tires on the left and right at once by jacking up, but the jacking up itself is a labor-intensive work, and it is dangerous to perform jacking up on an actual ice and snow road. Not realistic. Therefore, the present invention provides a non-slip device for a tire, which can reduce the trouble of moving the vehicle when mounting the tire on the tire by moving the vehicle.

[0007]

[Means for Solving the Problems]

 That is, the anti-skid device of the present invention is a tire anti-slip device having a split connection part in the middle of one tightening rope, and the split connection part is symmetrical between the right anti-slip device and the left anti-slip device. It is characterized in that it is provided as follows.

A detailed description will be given below with reference to FIGS. 1 to 3. FIG. 1 (A) is a plan view of the chain of the present invention as seen from the ground side, and as shown in the figure, it is entirely ladder-shaped and has tightening ropes 1 on both sides and a plurality of anti-slip plates 4 between them. Are installed at approximately equal intervals. The anti-slip plate 4 is, for example, provided with concavities and convexities on the ground contact surface side and is also provided with spiking pins (not shown), thereby further improving the anti-slip effect. End fittings 3 are provided at both ends of the tightening rope 1, and when attached to a tire, they are connected to form a ring-shaped chain.

Further, in the middle part of one of the tightening ropes, there is a disconnection connecting part 2 for facilitating attachment to a tire, and this connecting part 2 can be connected by an engaging metal fitting (not shown). Is configured. A feature of the present invention is that the disconnection connecting portion 2 is provided so as to be symmetrical between the right and left anti-slip devices. When the rope with the connecting portion 2 is mounted, it is located on the side of the vehicle as the outer rope 1a, and is provided symmetrically for the right rope and the left rope, respectively. , When the vehicle is installed, it can be moved forward or backward once.

Incidentally, FIG. 1 (B) shows a modified arrangement of the chain in FIG. 1 (A) with respect to the traveling direction of the vehicle. In this case, the traveling direction of the vehicle is opposite to that in the case of FIG. It is possible to install it on both left and right tires with one forward or backward movement.

[0011]

[Action]

 The operation of the present invention will be described through the explanation of the method of mounting the above-mentioned anti-skid device on the tire. 2 and 3 are explanatory views of a method of mounting the tire on the tire. FIG. 2 shows the left side of the vehicle, and FIG. 3 shows the right side of the vehicle. First, from the left side mounting, the grounding surface of the chain 5 is set to the front, the side with the disconnection connecting portion 2 (outer rope 1a) is arranged so as to face the left side of the vehicle, and the chain 5 is put on the tire ( FIG. 2 (A)). Similarly, when mounting on the right side, place the chain contact surface on the front side, arrange so that the side with the disconnection connection part 2 (outer rope 1a) faces the right side of the vehicle, and put the chain 5 on the tire (Fig. 3 (A)). ). Then, the end connecting fittings 3 at both ends of each inner rope 1b are connected to each other, and the vehicle is moved backward (rotating the tire in the direction of the arrow) so that the chain 5 passes between the ground and the tire (see FIG. )), (Fig. 3 (B)), connect the end connection fittings 3 at both ends of the outer rope to complete the attachment.

In this way, by distinguishing the mounting positions of the engagement fittings for the right side and the left side, it is possible to mount the anti-skid device on both the left and right tires by one vehicle movement of forward or backward. . In this example, the ladder type chain is described as an example, but a net type chain can be similarly applied.

[0013]

[Effect of the device]

 As described above, according to the anti-skid device for a tire of the present invention, when the tire is mounted on the tire, the tire can be mounted on both the left and right tires by one vehicle movement of forward or backward movement, and the mounting work of the user can be performed. It can be easy.
