Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for tightening an anti-slip net for tires.

(Prior Art) As a conventional anti-slip net for tires, there is one as shown in Fig. 13, and this first slip net (B) has a net inside the net body (1) formed in a belt shape. A non-stretchable inner connecting rope (21) is fixed to the handle 1, and both ends of this connecting rope (21) can be connected to the mating U, and each latching hook is attached to the outside. A tightening rubber band (23) (see Fig. 15) can be hooked along (22).

When attaching this anti-slip net (B) to the tire,
As shown in Figures 14 and 15, the net (B) is wound around the outer circumference of the tire (C), and both ends of the connecting band part (24) at one end are inserted into the connecting parts (25) (25) at the other end. Connect both ends of the connecting rope (21) attached to the inside of the non-slip net body (b), and then connect the hooks attached to each of the hooks (26) on the outside of the net body (b). Hook the ring-shaped tightening rubber band to the stop hook (22), and
Tie the anti-slip net (B)! It is made to come into pressure contact with the outer peripheral surface.

However, as mentioned above, since the inner connecting rope (21) is non-stretchable, the outer side of the anti-slip net (1) cannot be completely tightened against the tire (C), and after installation, It is in a slightly looser state than it should be completely tightened.

With this, the anti-slip net (B) is completely tied.
It is not in close contact with (C).

For this reason, during running, the anti-slip net (B) may float or shift laterally relative to the tie r (C), which may lead to noise generation or damage to the anti-slip net (B) itself.

(Technical Problem) The technical problem to be solved by the present invention is to tightly adhere the anti-skid net 1 for a tire to the tire surface so as not to lift up or shift laterally.

(Means for Solving the Technical Problems) The technical means taken by the present invention to solve the above problems is to attach an anti-slip net to a tire, and to cover the inside of the anti-slip net with an elastic inner fastener. It is characterized in that it is tightened with an attachment band, and the outside is tightened with an elastic outer tightening band.

(Function) After wrapping the anti-slip net for tires around the tire and connecting both ends, when the inside of the anti-slip net is tightened with the inner tightening band, the inside of the anti-slip net will be drawn towards the center of the tire and the inside half will be closed. When the net tightly adheres to the tire surface and the outside of the anti-slip net is tightened with the outer tightening band, the outside of the anti-slip net is pulled towards the center of the tire and the outer half tightly adheres to the tire surface. , the entire anti-slip net adheres strongly to the tire surface with uniform tension.

When driving, when centrifugal force is generated due to tire rotation, the inner connecting lobe becomes tense and C? ￥J The anti-slip net tries to spread outward, but the inner tightening band attached to the inside of the anti-slip net tries to contract and suppresses the inward expansion, and the outer tightening band attached to the outside of the anti-slip net tries to contract. To prevent an attachment band from expanding outward when it tries to contract, and to strongly hold both inner and outer edges of an anti-slip net that is about to spread toward the outer periphery.

(Effects of the Invention) Since the present invention is configured as described above, the tire anti-slip net attached to the tire is pulled toward the center of the tire by the inner tightening band, and the inner half is brought into contact with the tire surface. The outer side is pulled toward the center of the tire by the outer tightening band, and the outer half is tightly attached to the tire surface. Therefore, the entire anti-slip net can be drawn toward the center of the tire with a uniform force and brought into close contact with the tire surface, thereby preventing troubles caused by slipping or lifting of the anti-slip device during driving.

Therefore, the intended purpose can be achieved.

(Example) Embodiments of the present invention will be described below based on the drawings.

FIG. 1 and FIG. 2 show that the anti-slip tire net (A) is attached to the tire r (C), and is tightened by the inner tightening band (al) by implementing the tightening method of the present invention.
The figure shows a state in which the anti-slip net (A) is tightly attached to the tire (C) surface by tightening the outer side with the outer tightening band (a2).

As shown in Figure 3, the anti-slip net (△) is a non-stretchable net that runs along the inner and outer edges of the net body (1), which is formed into a band by appropriately braiding wire materials with a high-tensile core material inside. Attach the connecting lobes (2) (2'), and attach the hooks (2) (2') to both connecting lobes (2) (2') at appropriate intervals.

3), and at the same time, strongly stretch the loop part (6) on the other end side and hook it on the latching hook (3) at an appropriate position, and strongly tighten the inside of the anti-slip net (A).

As a result, the anti-slip net (A) has a tire (C) on the inside.
It is pulled towards the center and the inner half becomes the inner tire (C
) will be in a state of strong adhesion. It should be noted that the inner tightening band (al) does not necessarily need to be tied together in plurality as described above, but one band formed into a ring shape of an appropriate size can be crushed as it is, as shown in Fig. 7. Attach the hooks along each of the inner hooks (3), and hook the loops (6) (6) formed at both ends to the hooks (3) at appropriate positions in the same manner as described above. Stop, anti-slip net (A
) may be strongly tightened on the inside.

Next, as shown in FIG. 6, both ends of the outer connecting lobes (2') are connected in the same manner as described above, and then the outer tightening bands (al) are attached along each of the outer hooks (3'). Attach.

The outer tightening band (al) is the same as the inner tightening band (al).

(3'), and attach each hook in a circular manner along each hook (3'). Then, an appropriate number of outer tightening bands (al) are sequentially attached in an annular manner along each of the hooks (3') by the same operation as lo1, and the outer side of the anti-slip net (A) is strongly tightened. As a result, the outer side of the anti-slip net (A>) is drawn toward the center of the tire (C), and the outer half of the anti-slip net (A> is in close contact with the tire (C2)).

The number of outer tightening bands (al) to be attached may be one, but by increasing the number by two or more as necessary, the outer side of the anti-slip device (Δ) can be tightened more strongly (
You can

This completes the operation of attaching and tightening the anti-slip net (A) to the tire (C), and the inside half of the anti-slip net (A) is tightened by the inner tightening band (al). It tightly adheres to the tire (C), and the outer side is strongly tightened by the outer tightening band (al), so that the outer half is tied tightly.
