Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a fastening method and a fastening device for attaching a tire anti-slip device to a tire.

[Prior art] As a non-slip device used to prevent slipping when a vehicle is running on a snow-covered road surface, a pair of anti-slip bodies that extend across the tire tread and that go around the tire side part in an annular manner are used. There are some that are connected to connecting cables such as ropes and arranged in parallel at required intervals to form a ladder-like structure.

To attach and fix this anti-slip device to a tire, for example, as shown in Fig. 5, after wrapping the anti-slip device (A) around the outer circumference of the tire (T) and covering it, two The rope bodies (2') (2°) for connecting ropes, etc. are each tied in a ring shape.

Conventionally, hook metal fittings (5') having both ends bent into a hook shape have been used as a fastening means for this cable (2°), and the loops (2a) provided at both ends of the cable (2°) have been used. ')(2
b') was hooked onto the hook portion of the hook fitting (5°) and fastened in a ring shape. In order to facilitate the above-mentioned hooking work, the above-mentioned cable body (2゛) has a circumference slightly longer than the necessary circumference when it is tied in a ring shape, so that there is some margin. There was some slack left in the cable (2") when it was tied.

Therefore, in general, tires (T
), an auxiliary band (to') with a shorter circumference than the anti-slip device (A) is arranged concentrically with the tire (T), and is made of an elastic material such as rubber and has a hook, etc. at the end. A tightening member (11') having a locking part is attached to an auxiliary band (
The cable was hung in tension at multiple points between the cable (10°) and the cable (2°), and the cable (2°) was pulled toward the center of the tire to remove slack and maintained in tension. .

[Problems to be Solved by the Invention] In the case of the above conventional fastening method, a plurality of tightening members (11') are provided between the auxiliary band (10°) and the rope body (2°) of the anti-slip device (^). It is troublesome and time-consuming to hang the straps, and it requires quite a lot of force, so it is not something that anyone can easily tie, and there is a problem in how easily they can be attached to tires.

Moreover, since the length of the rope body (2) of the anti-slip device (^) is fixed and cannot be adjusted, the range of tire sizes that can be used with the non-slip device (-) is limited, and at retailers etc. , it was necessary to keep in stock many types of anti-slip devices of different sizes depending on the tire size.

In addition, in order to adjust the length of the anti-slip tool (A), it is possible to use the hook metal fittings (5°) with different lengths or to use a fastening structure that can be tightened. However, there are problems in that it is necessary to prepare multiple hook fittings of different lengths, and the structure becomes complicated and costs increase.

Therefore, although their use is desired in view of the dust pollution caused by spiked tires, the actual situation is that anti-slip devices for tires are not widely used.

The present invention has been made in view of the above-mentioned problems, and it is possible to easily fasten a tire slip prevention device, that is, to fasten a connecting rope, and also to easily and steplessly adjust the length of the rope. It is an object of the present invention to provide a fastening method and a fastening device that can be carried out without slipping or loosening in the fastened state, and can reliably maintain a good fastened state.

[Means for Solving the Problems] In the method for fastening a tire skid device of the present invention which solves the above-mentioned problems, one of the connecting ropes, such as two ropes, that connects the anti-slip body of the skid device. Two armors are attached to one end of one of the ropes in a hinge-like manner so that they can be opened and closed, a non-slip device is wound around the tire outer circumference, and both ends of the other rope are fastened together. To attach the mirror to the cable body, insert the end opposite to the one end through the two gongs on the one end from one side, wrap it around a part of both armors as a core, and then pass it through the mirror on one side again and attach it to both ends. Pull it out from the hall of mirrors,
It is characterized in that both chains tighten this pull-out end by the tensioning action of the cable.

The fastening device includes anti-slip bodies that are stretched along the tire tread surface and suspended between two connecting rope bodies that can be circumferentially circumferentially arranged at a required interval on the side of the tire. In an anti-slip device for tires, two armors are attached to one end of at least one of the cables in a hinge-like manner so that they can be opened and closed, and the other end of the cable can be inserted into the two mirrors and between the two cables. This is how it was done.

[Function] According to the above-mentioned fastening method and device of the present invention, after wrapping the anti-slip device around the outer circumference of the tire and fastening both ends of one of the connecting ropes, To attach the hooks to one of the connecting ropes, insert the end opposite to the one end into the two hooks at one end from one side, wrap around a portion of both ropes as the core, and then attach the end of the rope again to the anchor on one side. It can be tightened simply by passing it through the rope, pulling it out from between the two gongs, and pulling strongly to tension the rope.

In other words, when the cable is pulled, the winding part acts on the principle of a movable pulley to tighten both threads with twice the tension of the cable (7). As a result, the end of the cable pulled out from between the two cables is strongly compressed by both cables, and in particular, it is compressed so strongly that a tensile force is applied. Coupled with the Y friction resistance between the cables, the cables can be connected without fear of loosening or shifting, and can be maintained in a completely fastened state.

In addition, in the above, when the cable is loosened or stretched, both ends can open like a hinge with a certain opening angle, and the end of the cable inserted between the two ends is not crimped, for example. By loosening the cable at the fastening portion and adjusting the length of the drawn-out end, the circumferential length of the cable connected in an annular manner can be adjusted steplessly and easily.

Furthermore, when removing the cable, if the cable is loosened in the same way as described above, both ends will open, and the cable, such as a rope, can be pulled out without difficulty.

[Example code] Next, embodiments of the present invention will be described based on the drawings.

In the figure, (^) indicates the anti-slip device for tires to be fastened, and this anti-slip device (A) consists of a plurality of anti-slip bodies formed in the form of strips of a required thickness from rubber material reinforced with cords, etc. (1) and two connecting rope bodies (2) and (3) such as ropes that connect these anti-slip bodies (1). Through-holes (4) in the width direction are provided at both ends of the anti-slip body (1), and the cable bodies (2) and (3) are directly inserted into the through-holes (4) as shown in the figure. Alternatively, by connecting the metal fittings to the cable body (2) through a connecting metal fitting (not shown), each anti-slip body (1) is arranged at a required interval and the two cable bodies (2) and (3) are connected to each other. It is suspended on. The anti-slip body can also be connected to the cable body by means of connection means other than those described above.

The length of the above-mentioned rope bodies (2) and (3) is that of a tire (T).
The outer circumferential length of the tire (T) is substantially equal to or slightly longer than the outer circumference of the tire (T), and can be connected in an annular manner when attached to the tire (T). The length of the cables (2) and (3), which is approximately equal to the circumference when the tires are blued, is 6 to 6.
Divide into 16 equal parts, use the equal length as the pitch length, and place the same number of anti-slip bodies (1
) to constitute a ladder-shaped tire slip stopper (A).

In the present invention, among the two connecting cables (2) and (3) of the anti-slip device (A), one end (21) of one of the cables (2) has a substantially same shape. Two G (5a) (5
B>, with both of them overlapped, pass the end of the cable body (2) through this, fold back with the - part of both B (5a) and (5b) as the center, and connect the folded end (21a) to the cable. Body (2
) is attached to the main part (20) of the Ex (5a) (5b) by an appropriate means so that it can be opened and closed like a hinge, thereby making it possible to change the opening angle (α) of the two Ex (5a) (5b). , the other end (22) of the cable body (2) is inserted into these two 8 (5a) (5b) and both ends (5a).
(5b) so that it can be inserted between the two. This becomes the fastening device in the present invention.

The above-mentioned 8 (5a) and (5b) are not limited to the shapes shown in the figures, but are circular, oval, or have an irregular armor shape with constricted sides, so that the cable (2) can be inserted through it. In addition, the sandwiching between the two can be implemented in various forms, and the material can also be made of a rigid material other than metal.

In addition, both ends of the other cable body (3) are formed into ring-shaped parts (3a) and (3b) in the same manner as before, and both ends are bent using hook fittings bent into a key shape. Form it so that it can be connected. Of course, it is also possible to provide and implement connection means with other connectable structures.

Then, attach the above anti-slip device (A) to the car tire (T).
When installing it on a tire, for example, attach the side of the connecting cable (2) having the fastening device according to G (5a) (5b) above to the tire (
The anti-slip device (A) is placed outside the anti-slip device (A
) around the outer circumference of the tire (T). In this way, the rope body (3) located inside the tire (T) is connected in an annular manner by joining both ends of the rope body (3) by using a hook fitting similar to the conventional method.

Thereafter, both ends of the other cable body (2) located outside the tire (T) are fastened in the procedure shown in FIGS. 3(a) to 3(d).

That is, first, as shown in FIG. 3(a), the cord body (2)
Two prongs (5a) attached to one end (21) of (
5b), attach the other end (22) of the cord (2) to both jE

) as a core, wind it as shown in Figure (b), then pass it through 8 (5a) on one side again and pull it out from between the two armors (5a) and (5b), as shown in Figure (c). , chordate (2
) Just pull it hard to make it tense.

In this way, when the pull-out end (22a) of the cable (2) is strongly pulled, both mirrors (5a) are
The winding portion (22b) of the cable (2) around (5b) tightens both Et (5a) and (5b) using the principle of a movable pulley with a force approximately twice as strong as the above-mentioned tensile force. the result,
The base of the pull-out end (22a) of the cable (2) pulled out from between both G (5a) (5b) is connected to both jE2 (5a).
) (5b) The stronger the clamping pressure is applied, and the more a particularly strong tensile force is applied, the more strongly the crimping is performed, preventing the connector from being pulled out and reliably keeping it in the fastened state.

In particular, the ends of the cable body (2) are connected to both Ji! (5a) (5b
) by winding it several times and pulling it out from between the two armors, the above-mentioned connection will become even stronger.

In addition, in the state where the cable body 2) is loosened or stretched (as shown in Figure 3 [C]), both 8 (5a)
(5b) Since the end of the cable (2) inserted between the cables (2) is not crimped, the pullout end (22a) may be pulled out while loosening the main body (20) side of the cable (2), or vice versa. Push the end (22a) into the main body (2).
0) Cable body (2) connected in a ring by pulling the side
The circumference can be adjusted steplessly and without difficulty.

Furthermore, when removing the cable, if the cable body (2) is loosened in the same manner as described above, both Q (5a) and (5b) will open, and the cable body (2) such as a rope can be pulled out without difficulty.

Note that the above cable body (2) is also attached to one end of the other cable body (3).
), attach two armors with the same configuration as in the case of
It can also be constructed so that it can be fastened in the same manner as described above. In this case, the possible range of length adjustment according to the tire size is expanded.

[Effects of the Invention] As described above, according to the present invention, the fastening device can be easily used by simply inserting the other end into the two armors attached to one end of the cable, winding the rope, and pulling out the end. Due to its simple structure, the fastening operation can be easily performed during use, and it can be quickly attached to the tire. Furthermore, the force required to pull and tighten the rope is small, so anyone can easily install it, and it is possible to maintain a secure and secure fastened state.

In addition, since the circumference of the rope can be easily and steplessly adjusted, fluctuations in tire size can be absorbed, and a single anti-slip device can be used for tires of different sizes, widening its range of use. There will also be fewer types of products in stock at stores, etc.

Furthermore, since it does not require auxiliary devices such as auxiliary bands and tightening members as in the past, the structure is simple, and
It can be produced at low cost and provided at low cost.
