Abstract

PURPOSE:To facilitate the fitting and improve the adhesion by putting an endless non-slip net made of rubber and slightly longer than the peripheral length in the radial direction crossing the grounded section of a tire and having a width nearly equal to the tire width into close contact with the tire by use of a tension means. CONSTITUTION:An endless, belt-like, non-slip net (a) made of rubber is formed so that its length is slightly longer than the peripheral length in the radial direction crossing the grounded section of a tire b1 and its width is nearly equal to that of the tire b1. Said net (a) is covered from above the tire b1, suspended on an axle 6 inside the tire b1, and drawn down outside the tire b1. Next, the whole net (a) is fed to inside the tire b1, then withdrawn to the outside, the net (a) is covered along the outer periphery of the tire b1, and a hook 2 is coupled with a ring 3 to bring the net (a) into close contact with the tire b1. According to this constitution a non-slip tool can be fitted easily and reliably.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an anti-slip device that is attached to the tires of the wheels of an automobile to enable it to run on snow. Various anti-slip devices have been proposed in the past as anti-slip devices for tires. Among them, there are some that use rubber anti-slip nets.

This type has the advantage of not damaging the road surface and making low noise when the car is running, but on the other hand, it is relatively expensive and the installation method is the same as the normally used metal tire chain. Therefore, it is time-consuming to install the anti-slip net.In other words, the anti-slip net has a mesh shape and is wider than the width of the tire, resulting in high manufacturing costs.

In addition, the installation method is to first wrap the net around the outer circumference of the tire with the wheel jacked up, connect both ends of one side of the net with a connector inside the tire, and then pull the net out to the outside of the tire so that it remains the same. Piece 911
Connected by one 44e connector.

Then, the periphery of the net on the outside of the tire is tensioned by a tensioning means made of a spring material, a rubber material, or the like to bring the net into close contact with the tire.

The most troublesome task in the above operations is to connect the ends of the net inside the tire, which is difficult to access.

After trying all 47 mounting methods to eliminate this troublesome work, I came up with the following simple but workable method.

That is, the net is made endless in advance, and the net is wrapped around the tire from above in the radial direction across the ground contact area.

Then, the periphery of the net that went around the inside of the J tire is hooked to the axle, and the same order of the net that extends outside reaches the bottom of the tire.

In this state, after feeding the entire net to the inside of the tire, wrap the net around the outside of the tire and
The attachment is completed by pulling out the same edge on the outside j and tensioning it with a tensioning means.

However, even with the above mounting method, with conventional nets, the length is one length longer than the full contraction of the tire, and the width is wider than the width of the tire, so there is too much net on the outside of the tire, and the net is tightly tensioned. If this is not done, there is a risk that the net will not adhere to the tire sufficiently.

The present invention has developed an anti-slip device suitable for the above mounting method, and an object of the present invention is to provide an anti-slip device that is inexpensive to manufacture, easy to install, and can bring the net into close contact with the tire VCM and actual VC. It is.

An example of the implementation of the present invention will be explained with reference to the drawings. As shown in Figs. It has a tension means to make it tense when it is pressed.

Said net) (a) is made of a rubber material and is made into a belt-like endless ring forming a mesh, and is elastically deformable and expandable.

Note that the rubber material constituting the net (a) is softer than the rubber material of the tire [bl] so as not to damage the tire (bl).

Further, the net (a) may include a core material such as piano wire as a reinforcing means.

The dimensions of (a) above are the length of the tire (bt).
) is slightly longer than the circumference in the radial direction across the ground contact area, and the width is approximately equal to the width of the tire (b).

On the other hand, the above-mentioned tensioning means is provided on the same edge on the outside of the tire (bl) when it is attached to the tire (bθ) in (a), and an elastic string (1) made of rubber material or the like is attached to the same edge on the outside of the tire (bl). Tie each mesh and each elastic string (1)
By attaching a hook (2) to the end of the wheel, and pulling the string (1), the hook (2J'f: wheel (b), a ring (3) consisting of a rigid body in the middle of the wheel (b)) is secured.
It's starting to make Net 0 nervous.

In addition, when installing the tire (b) in the above net) (a),
A wire rope (5) is attached to each mesh of the river edge through a loop (4) on the river edge inside the mesh.

This wire gauge (5) regulates the elongation of the net (a) at 11i of the tire (b,) and the net &! This is to prevent the tire (L) from coming off the tire (111θ), and is made of a flexible material. It is designed to be connected.

5- That is, when the anti-slip device is not used, the wire rope (5
) is removed from the net (a) so that the net (a) can be easily folded.

The anti-slip device is mounted on the tire (bl)vc by the procedure shown in FIGS. 4 to 6.

That is, first, as shown in Fig. 4, put the net (a) over the tire (bs) from above, and place it on the inside of the tire (bl). (Net on the outside of (bl)) Lower (a).

Next, as shown in FIGS. 5 and 6, the entire net (a) is fed into the inside of the tire (bθ) and then pulled out to the outside, and the net (a) is placed along the outer circumference of the tire (bl).

Then, the net (a) is tensioned by being hooked to the hook (2) and the ring (3), which are tensioning means.

The anti-slip device installed in this way is a net (b))
is stretched by its own elastic and tensioning means to form a tire (b
Close contact with l).

As explained above, the present invention is such that the anti-slip net 6 has a length M that is slightly longer than the radial growth that cuts the ground contact area of the tire, and has a width that is almost as large as the width of the tire. Because of this, the length and width are shorter than conventional nets, which saves material costs, and the net connectors are unreliable, making manufacturing costs low.

The length of the net mentioned above is longer than the entire circumference of the tire, and since the net is endless, it can be attached to the net by covering the tire from above, and it can be attached to the inside of the tire like in the past. There is no need to perform the work of connecting the net with each other, and the installation procedure can be easily performed, and in the installed state, the net stretches due to the elasticity of the 7'n' body and securely adheres to the tire.
