Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a tire chain structure for large trucks such as tank trucks and trailers.

[0002]

[Prior art]

 The drive wheels (rear wheels) of large trucks such as tank trucks and trailers are usually mounted in double layers. When chaining this, chain the outer tires.

[0003]

[Problems to be solved by the device]

 However, since the car body is large, it cannot be jacked up like a passenger car, and when tire wheels are needed on snowy roads, the scaffolding is usually bad. It is extremely difficult to wear, and even a driver familiar with snowy roads is forced to chain the chain in the snowstorm for 10 to 15 minutes.

[0004]

[Means for Solving the Problems]

 The inventor has been driving a tank truck for many years, and has been paying attention to running on this snowy road every winter, and has conducted research on how to improve the chain. In addition, we have succeeded in easily connecting the chain using the hole of the tire wheel by using the hook-shaped rod, and by attaching a mark to this chain, attaching and detaching the chain Is made easy.

[0005]

[Action]

 Therefore, when using this chain, no matter how bad the scaffolding is, even if it is a night road, it is possible to dismount the chain almost by fumbling, and even an inexperienced person can wear it in less than 5 minutes. It provides an epoch-making chain that can be installed in about 1 minute, and can be installed and removed without hassle, which greatly contributes to the prevention of accidents on snowy roads. is there.

【Example】

 The tire chain of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a plan view of a tire chain A, in which A-1 indicates a chain that is hung inside a tire T to be mounted, and A-2 indicates a tire T. Shows the chain hanging on the outside of the. A spring book (1) is attached to one end of the A-1 side chain, and a ring (2) is attached to the other end, and a hook-like hook (3) is attached to one end of the A-2 side chain. A ring (2) is attached to the other end.

Therefore, this tire chain A is different, including chains for small cars, except that a spring hook (1) is provided at one end of the chain A-1 that hangs inside the tire T. Further, the feature is that a mark (6) is provided at a central position with respect to the length of the chain A-2 that extends outward. The mark (6) is not particularly specified, but a ribbon is tied in the figure.

Further, the spring hook (1) is an ordinary commercially available hook metal fitting shown in FIG. 2, in which the portion (5) is opened and closed by the spring shaft (4), and only one side is provided in the direction of the arrow. It is configured to be closed by the action of the opening spring shaft (4).

FIG. 3 is a plan view of the operating rod B, which is a steel rod whose both ends are bent and formed into a hook shape (10). Therefore, the heavy-duty truck tire chain of the present invention is thus constituted by the chain A and the operating rod B.

Next, the way of attaching and detaching the tire chain A of the present invention will be described. First, referring to FIG. 4, regarding the attachment, the tire T shown in the figure is a large truck (see FIG. 5 is a tank truck vehicle). The rear wheel (driving wheel) is a tire on the outside of the tire that is double equipped, and the mark (6) of the chain A is directed to this tire T, and the mark (6) Hang it on the tire T so that is directly above the tire.

Then, since the chain A-1 hangs down on the back side of the tire T, the spring hook (1) and the ring (2) at both ends are scraped from the hole (11) of the tire wheel F by using the operating rod B. , Insert both hands through the hole (11) in the wheel F and connect. Since this connection is a spring hook (1), the ring (2) can be easily connected by groping. Then, the hook (3) of the chain A-2 on the front side of the tire T is engaged with the ring (2). Since this engagement is on the outside of the tire T 1, it can be easily engaged and the mounting of the chain A is completed. K in the figure is a rubber band for tensioning the chain A.

[0012] Next, as shown in Fig. 5 showing how to remove the chain A, when the vehicle is stopped, the driver puts the mark (6) of the chain of the tire on which the chain A on the rear is hanging at the lowest position. Stop the car. At this time, if you put a mark M on the tire cover of the car on the eyes of the driver's hand and the mark of the chain mark (6) with colored tape etc., the driver moves the car while looking backwards and looking at it. When the mark M on the tire cover and the mark (6) on the chain line up with each other, stop the car.

When the vehicle is stopped in this manner, the engaging portion of the tire chain A is located directly above the tire T, so that the hook (3) of A-2 on the front side is, of course, removed. The spring book (1) of the chain A-1 on the back side can be easily removed by putting a hand in the hole (11) of the wheel F.

[0014]

[Effect of the Invention] Since the tire chain A of the present invention has the above-described structure, it is possible to dismount the chain almost by groping no matter how bad the foothold is on a snowy road or on a night road. Since the chain can be attached and detached very easily and easily, it has an epoch-making effect that greatly contributes to the prevention of accidents on snowy roads.
