Description

[Detailed description of the invention] (Field of industrial application) This invention relates to an anti-slip net for tires.

(Technical Background) Most of the conventional anti-slip nets for tires are braided to form a diamond-shaped mesh as shown in FIG.

The above-mentioned mesh pattern is designed in consideration of continuous grip and productivity, and when manufacturing the anti-slip net, multiple (5 to 6) synthetic rubber filaments 31 are arranged in a zigzag pattern. We use a manufacturing method that involves interlacing and braiding.

Originally, anti-slip nets were used to ensure tire grip on snowy roads, and were required to prevent tires from slipping in the circumferential and lateral directions. Since it is diamond-shaped, each of the filament members 31 forming the mesh stands obliquely with respect to the tire circumferential direction and the tire width direction. However, as described above, the diagonally inclined linear members 31 cannot efficiently grip the snow on the road surface when the brakes are applied and the tire skids in the direction of travel, and it is difficult to grip the snow on the road surface efficiently. Also, it cannot be said that it has an effective function of preventing slips in the lateral direction.

Currently, an anti-slip net B as shown in FIG. 4 is being considered in order to solve the above-mentioned grip problem.

This anti-slip net B is provided with a plurality of, for example, five vertical wire members a made of synthetic rubber running parallel to each other in the entire length direction of the anti-slip net main body 21. The anti-slip net main body 21 is meshed in a lattice shape by intersecting the horizontal striations b with the longitudinal striations, and when installed, the longitudinal striations a and the horizontal striations b cross in the circumferential direction and width direction of the tire. When the tire slips in the circumferential direction and in the lateral direction, the vertical or horizontal stripes b catch the snowy road surface at right angles, thereby preventing the tire from slipping in the circumferential direction and in the lateral direction. It is an enhanced version of

However, when the anti-slip net B having the above structure is wound around a tire and attached, both sides of the anti-slip net main body 21 hanging over the shoulder D ₂ of the tire D loosen, as shown in FIG. A problem arises in that the net main body 21 cannot be reliably attached in close contact with the tire surface.

The above-mentioned problem is caused by the fact that a plurality of vertical wire members a and a' are provided to extend in the entire length direction of the anti-slip net body 21 in order to improve the grip property in the lateral direction. When the net B is attached to the tire, the vertical wire members a' and a' on both sides of the anti-slip net body B, which hang on the shoulder part _D2 whose peripheral diameter is one size smaller than the tread part _D1 , cannot be contracted. The cause is that it becomes loose.

Incidentally, in the conventional anti-slip net C, the above-mentioned problem does not occur because the diamond-shaped meshes 32 on both sides of the anti-slip net are deformed so as to collapse in the circumferential direction.

(Technical Problem) The technical problem of the present invention is to improve the grip of an anti-slip net for a tire in the circumferential direction and lateral direction of the tire, and to make the anti-slip net fit and attached to the tire.

(Means for solving the technical problems) The means taken by the present invention to solve the above-mentioned technical problems is to install a plurality of vertical wire members mainly made of synthetic rubber parallel to the entire length of the anti-slip net. At the same time, horizontal wire members similar to the vertical wire members are intersected with the above-mentioned vertical wire members to form the non-slip net main body in a lattice shape, and vertical wires on both sides of the non-slip net main body are provided. The length of the wire material is made shorter by a predetermined amount than the vertical wire material at the center of the main body of the anti-slip net.

(Function) According to the above configuration, when the anti-slip net is wound around the tire and the ends are connected to each other, the vertical wire material at the center of the anti-slip net body is wound around the tread portion of the tire, and the above-mentioned The wire members on both sides of the net main body, which are configured to be shorter than the wire members by a predetermined amount, are wound around the shoulder portion of the tire to fit. The vertical and horizontal wire members of the attached anti-slip net become protrusions that run in the tire circumferential direction and the tire width direction.

During braking and starting, when the tire slips or spins in the direction of travel, the horizontal wire material faces the tire and moves in the direction of travel at a right angle to the snowy road surface (the direction in which the road surface moves and the direction in which the wire material travels). grip at a right angle).

Further, when the tire skids while the vehicle is running, the filament members extending in the circumferential direction of the tire catch the snowy road surface moving laterally opposite the tire at right angles.

(Effects) Since the present invention is as described above, it is possible to improve the grip of the tire in the circumferential direction and the lateral direction on snowy roads, and therefore, it is possible to suppress slips, slips, and skidding during braking. can.

In addition, in order to improve the grip property, the anti-slip net body may be constructed in a lattice shape by intersecting the longitudinal stripes running in the overall length direction of the anti-slip net and the horizontal strips running in the width direction. The vertical wires on both sides of the net body are made a predetermined amount shorter than the vertical wires in the center of the net body, so both sides of the anti-slip net body can be wrapped around the shoulder of the tire, making the anti-slip net It can be installed securely with the whole thing fitted to the tire.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

The anti-slip net A is made of vertical filaments a ₁ to a ₅ and horizontal filaments made of synthetic rubber reinforced by internally reinforcing a high-tensile core material C such as wire, synthetic fiber such as nylon, or glass fiber. A strip-shaped anti-slip net body 1 is formed by meshing the material b in a lattice shape, and hooking portions 1a for attaching the hooking fittings 2 are provided on both sides of the body 1, and one side edge of the net A tightening rope 3 is attached to each latch 2.

The anti-slip net main body 1 has five vertical stripes a ₁ ... a ₅
While running parallel to the entire length direction of the main body 1,
A large number of horizontal wire members b are made to fly in the width direction of the main body 1 at regular intervals, and are intersected with the vertical wire members _a1 ... _a5 to form a mesh in a lattice shape.

The vertical strip in the center of the above-mentioned anti-slip net A
A ₂ , a ₃ , and a ₄ are wound around the tread portion D ₁ of the tire D as shown in Fig. 5, and are formed to have approximately the same length as the circumference of this tread portion. .

Further, the vertical wire members a ₁ and a ₅ on both sides of the anti-slip net main body 1 are connected to both shoulder parts D ₂ and D ₂ of the tire D.
The same vertical wire material a ₁ and a ₅
The length l ₂ is the length that matches the circumference of the shoulder parts D ₂ and D ₂ of the tire to which the anti-slip net A is attached, and the length l 2 of the longitudinal wire members a ₂ , a ₃ , and a ₄ in the central part length
l Form a predetermined amount shorter than ₁ . As a result, the shape of both ends of the anti-slip net main body 1 becomes a shape as shown in the figure.

On both side edges of the anti-slip net main body 1 constructed as described above, latching portions 1a for attaching latching fittings 2 are provided at predetermined intervals. Further, connection bands 4, 4 are integrally formed at one end of the vertical wire members a ₁ and a 5 so as to face sideways, and the connection bands 4 and ₄ are integrally formed at the other end of the vertical wire members a ₁ and a ₅ . Connecting parts 5, 5 into which the bands 4, 4 are inserted and hooked are formed.

When attaching the anti-slip net A to the tire D, first wrap the anti-slip net A around the tire D, and insert the connecting bands 4, 4 at one end of the net A into the connecting parts 5, 5 at the other end. and then lock it, and then
After connecting both ends of the tightening rope 3 inside the tire, a rubber band 6 is hooked to the latch fitting 2 inside the tire D, and the entire net A is tightened and mounted on the tire C surface.

After installation, both ends of the anti-slip net A are aligned and connected in a substantially straight line as shown in FIG. This is done by adjusting the lengths of the vertical wire members a ₁ and a ₅ on both sides of the anti-slip net main body 1 to match the circumference of the tire shoulder portion D ₂ as described above, and adjusting the lengths of the longitudinal wire members a 2 and a in the central portion to match the circumference of the tire shoulder portion D ₂ . ₃ and A ₄ are formed shorter than each other, so when both connecting bands 4, 4 are inserted into and hooked to the connecting parts 5, 5, both ends of both vertical wire members a ₁ , a ₅ are drawn in so that they meet. By drawing both longitudinal wire members a ₁ and a ₅ , the anti-slip net A is attached with its both side edges in close contact with the shoulder portion of the tire D.
