JPS5913124Y2 - Anti-slip device for vehicles - Google Patents

Description

[Detailed description of the invention] The present invention relates to a non-slip device for vehicles, and more specifically, to prevent the slip of automobile tires on snowy roads, etc. This invention relates to a non-slip device for a vehicle comprising a tire chain that can be easily attached to and detached from a tire.

When driving a car when the road surface is icy or snowing, it is necessary to install tire chains to prevent the tires from slipping.

However, with conventional tire chains, you can lay them out on the road and move a sentry vehicle to position the tire at the desired position on the tire chain, or you can place the tire chain from above the tire and then It was not possible to attach tire chains to tires without going through the preparatory steps of moving the car and wrapping the chains around the tires in the desired state.

Therefore, in the preparation stage, it is difficult to move the car so that the positional relationship between the tire chain and the tire is in the desired state, and because of this difficulty, it is difficult to move the car by adjusting the position of the tire chain. To avoid adjusting the tire chain and operating the steering wheel with dirty hands, take off your work gloves or wash your oily hands. This has the disadvantage that it is extremely troublesome.

In addition, the work of connecting the ends of one side of the tire chain, which is located on the inside of the tire, that is, on the invisible side below the vehicle body, must be done by hand because it cannot be confirmed visually, and this can be done in a short period of time. Because it requires skill to do this,
For those who have little experience in installing tire chains,
This connection work also has the disadvantage that it takes a long time, and there are problems such as the occurrence of long road congestion.

The present invention was made in view of the above-mentioned drawbacks, and aims to provide a non-slip device for vehicles that is easy to attach and detach.The present invention is characterized by a pair of long chains arranged in parallel and connected at predetermined intervals in a ladder shape. Tires that are connected by chains and each end of one elongated chain 3 is connected to each corresponding midway part of both ends of the other elongated chain 2 with a loop portion provided therein. It consists of a chain and a wheel that has an appropriate number of through holes on both sides and a locking part near the through holes on the outside of the tire, and the long chain 3 is placed inside the tire. 2 is located outside the tire, and both ends of this long chain 2 are connected, and the slack portion of each loop portion of the long chain 3 located inside the tire is connected to the outside from the through hole of the adjacent wheel. This is where you pull it out and lock it in the locking part.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a tire chain, a pair of long chains 2,
3, and a plurality of appropriately connected chains 4a, for example, seven connecting chains 4a, for connecting these long chains 2 and 3 to each other.
4b, 4C, 4d, 4e.

I have been warned since 4f and 4g.

At one end of the one elongated chain 2, in order to connect with the other end, there is an engaging piece 5 which has an inverted S-shape and is rotatably supported by an iron ring at the end. A known locking member consisting of a locking ring 6 having an inverted T-shaped through-hole portion into which the tip end of the ring 5 is hooked, and a locking ring 6 that can only slide freely along the iron ring is attached.

Each end of the other elongated chain 3 is connected to one end of each of the connecting chains 4a, 4g, respectively, to form loop portions 13a, 13b.

This loop part 13 constitutes "drawing parts 3a and 3b" between the connecting chain 4a and the connecting chain 4b and between the connecting chain 4g and the connecting chain 4f, respectively.

The lengths of these pull-out portions 3a, 3b are set to be sufficiently longer than the lengths between the connecting chains 4a, 4b and between the connecting chains 4g, 4f in the other elongated chain 2.

7 is a tire to which the tire chain 1 is to be attached, and 8 is its wheel.

The wheel 8 has five diametrically long through holes 9a, 9b, 9C, 9d, 9e and 9f to communicate with each other on both sides.
, 9g, 9h, 9i, and 9j are transparently provided at equal intervals in corresponding positions on each side surface, and each through hole 9a.

Near both sides of the wheels 9b, 9C, 9d, and 9e in the wheel center axis direction are hooks 1 that are locking parts that protrude toward the center axis direction.
0 a, 10 b, 10 C, 10 d, 10 e
, 10f, 10g, 10h, 10 i, 10
j is integrally press-molded.

In addition, 11 in the figure is a vehicle body. Next, a method for attaching the tire chain 1 configured as described above to the tire 7 provided on the wheel 8 described above will be explained.

First, the long chain 3 is hung from above the tire 7 so that it is located inside the tire 7.

Next, as shown in FIG. 5, the pull-out rod 12, which has a generally arched shape and whose tip is bent into a hook shape, is pulled from the outside of the tire 7 so that one end of the long chain 3 has a corresponding loop portion 13a. The long chain 3 is inserted into the through holes 9C and 9i, and the loop portion 13a of the long chain 3 is hooked on the tip thereof, and the loop portion 13a of the long chain 3 is pulled out toward the outside of the tire 7.

Subsequently, the slack portion of the loop portion 13a that protrudes from the through hole 9C is engaged with the hook 10e.

The same operation as above is carried out on the other end loop part 1 of the long chain 3.
3b is also pulled out from the through-holes 9b and 9j, and the protruding slack portion thereof is locked to the hook 10d at the appropriate position, thereby completing the work of locking the inner part of the tire 7 of the tire chain 1.

Subsequently, as in the conventional method, both ends of the long chain 2 are connected and a rubber band (not shown) is hung thereon, thereby completing the installation of the tire chain 1.

In this way, according to the present invention, - Tire chains can be easily attached to tires equipped on wheels of a heavy structure without moving the vehicle, so handling is easy and work time is shortened. In this way, it is possible to achieve many excellent practical effects, such as being able to work without getting your hands or clothes dirty, and being easy to remove.

Various embodiments of the present invention have been described above, but it goes without saying that the present invention is not limited to the above-mentioned embodiments. Each end of the chain may be provided with a member specifically adapted to engage with the hook, and the pull-out portion of a long chain connected at both ends to a connecting chain may be covered with a vinyl tube to prevent damage to the tire. In addition, only one end of these pull-out parts may be connected to a long chain.Furthermore, the wheel that can be used has a through hole that communicates with both sides and a surface that corresponds to the outside of the tire. Of course, many modifications may be made without departing from the spirit of the invention, such as any other structure as long as it has a locking portion.
