[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tire slipper that is used by being wound around the outer peripheral surface of an automobile tire.

[0002]

[Prior Art]

 Conventionally, as this kind of tire anti-skid, a tire anti-skid 1 composed of an anti-slip body made of an elastic material such as rubber shown in FIG. 4 has been known (for example, see JP-A-62-128810). .. The anti-skid 1 shown in FIG. 4 comprises a ladder-like grounding part 3 in which the anti-skid body 2 is orthogonal to the longitudinal direction, a diagonal cross mesh part 4 connecting the grounding part 3, and connecting strips at both ends in the longitudinal direction. 5, and both ends in the width direction are hooked portions 6 and 7, and a high-tensile fiber such as nylon or a core material 8 made of an organic fiber (rubber-coated cord) is embedded inside.

Then, the anti-skid body 2 is wrapped around the outer circumference of the tire (see FIG. 5), the connecting belt portions 5 are opposed to each other and are connected using the connecting hooks 9 and 10, and the hooking portions are connected to each other. The non-stretch tightening cords 11 and 12 are hooked to the 6, 7 via the engaging hooks 13 and 14, respectively, and in particular, the outer side tension tightening cord 12 (rope or belt) of the tire T is tightened. Tightened with attachment 15.

Further, the core members 8 are arranged in a diagonal cross mesh shape, and intersect each other at the longitudinal connecting portions 6A and 7A of the hook portions 6 and 7, respectively.

[0005]

[Problems to be solved by the device]

 In the above conventional technique, when the anti-skid device 1 is attached to the tire T, the tightening cord 12 of the tightening device 15 is tightly tightened in the vicinity of the engaging hook 14 on the pulling side A as shown in FIG. The tightening condition of the tightening cord 12 fixed side B engagement hook 14 to the tool 15 is not good. Therefore, the tightening cord 12 is loosened immediately after the start of traveling, and the anti-skid body 2 is displaced and eccentric to prevent the anti-skid function. There is a problem that it cannot be emitted, and it is necessary to stop the vehicle and refasten (tighten) the tightening cord 12.

Further, since the core material 8 intersects at the connecting portion 7A of the hooking portion 7 of the anti-skid body 2 at a distance of 7A, even if the hooking portion 7 becomes loose, it cannot be absorbed and the tightening cord 12 Since the tightening due to the tightening becomes insufficient, the above-mentioned additional tightening work is indispensable. If the additional tightening is not performed, the original anti-slip function cannot be exhibited, and the service life will be significantly reduced. The present invention has been made in view of the above-mentioned circumstances, and the purpose thereof is to be able to absorb the looseness of the hooking portion and the like, and to perform the full anti-skid function without the need for additional tightening. To provide a tire slipper.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention takes the following technical means. That is, according to the present invention, a non-stretchable core material is embedded in a non-metallic material non-slip body, and a tightening cord is hooked to a hooking portion at each end in the width direction of the main body via an engaging hook. In the tire anti-skid device as described above, at least the core material arranged between the hooking portions on the outer side of the tire does not intersect with each other.

[0008]

[Action]

 According to the present invention, when the anti-skid device is attached to the tire, the core material does not intersect at least the longitudinal (circumferential) connecting portion of the hooking portion on the tire outer side due to the tightening of the tightening cord. Therefore, it can be properly extended in the width direction and the longitudinal direction, and the looseness and displacement of the hooking portion at the time of mounting can be absorbed. The slack that occurs immediately after running after wearing the anti-skid is absorbed by the elasticity between the connecting parts of the above-mentioned latching parts, and the eccentricity due to the deviation is naturally corrected to the optimum condition, causing problems such as detachment from the tire. To be prevented.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a first embodiment of the present invention. Since the basic structure of the tire slip stopper 1 is the same as that shown in FIG. 4, the same reference numerals as those in FIG. Description will be made also with reference to FIG.

The anti-skid body 2 of the tire anti-skid 1 is made of a non-metallic material such as rubber and has a strip shape. The rudder-like grounding portions 3 are parallel to each other and are orthogonal to the longitudinal direction thereof. It is equipped with a diagonal cross mesh part 4 for connecting with each other and connecting strips 5 at both ends in the longitudinal direction, and each widthwise edge is a catching part 6,7, and a non-stretch (high tension) fiber (for example, nylon, organic A cord-shaped core material 8 in which fibers and the like) are covered with rubber is embedded over the entire surface.

The core material 8 has one line, and every other one of the ladder-shaped grounding portions 3 from one end in the longitudinal direction intersects at the connection portion 6A between the hooking portions 6 on the inner side of the tire, and the ladder-shaped grounding portion 3 And the connecting portion 7A between the hooking portions 7 on the outer side of the tire are arranged so as to reciprocate so as not to intersect with each other. The connecting portion 7A easily extends in the longitudinal direction (circumferential direction) and the width direction, and the loosening absorbing function is secured. Has been done.

Reference numerals 9 and 10 are linking hooks made of a metal material, which are wound around the tire T to connect the linking strips 5, 5 as shown in FIG. 5. The linking hook 9 on the inner side of the tire is one The connecting band 5 is fixed to one end by caulking, one end of the tightening cord 11 is fixed, and the hook 9A is connected to the locking ring 11A formed at the other end of the tightening cord 11. The other link hook 10 is for connecting the link strips 5, 5 on the outer side of the tire and has two hook portions 10A, 10B on the side of the anti-skid body 2 and one of the hook portions 10A is The connecting band 5 is fastened to the other end (outer side of the tire) by caulking, and the hook part 10B on the other side is hooked on the connecting band 5 of the other side to connect both connecting bands 5,5. The hook portion 10C formed on the tightening cord 12 side is locked to the fastener 15.

The tightening cords 11 and 12 are made of a non-stretchable material. An endless rope is used for the tightening cord 11, and a metal member whose one end is caulked and fixed to the hook portion 6 of the anti-skid body 2. The other side of the combined hook 13 is fixed to the tightening cord 11 by crimping. An end rope or a belt is used for the tightening cord 12, and it is hooked and engaged with a metal engaging hook 14 fixed by caulking to the hooking portion 7 on the outer side of the tire, and a tightening tool 15 is used. The ends of the tightening cords 12 are linked together and tightened.

The tightening tool 15 has been conventionally used, and is provided with a rope locking means (not shown), and the tightening rope 12 is hooked on the engaging hook 14 fixed to the anti-skid body 2. The end portion 12A of the tightening cord 12 engaged with the attachment 15 is pulled and fixed. In the first embodiment described above, the attachment of the anti-skid device 1 to the tire is carried out by the same operation as in the conventional example, but since the core material 8 does not intersect at the connecting portion 7A between the hooking portions 7, it expands and contracts. Compared to the example, it is simpler and easier to tighten, and it can be done in a short time, and the entire part excluding the connecting part 6A between the latching parts 6 extends, so a centripetal force acting toward the axle axis acts, and the anti-skid body 2 Problems such as displacement caused by eccentric mounting are eliminated.

Furthermore, the looseness that occurs immediately after the start of running after the anti-skid device is attached is absorbed by the elasticity of the connecting portions 7A between the latching parts 7, and the slippage, eccentricity, etc. of the anti-skid device body 2 when it is attached are It will be naturally corrected inside and it will be in the optimal wearing state, exhibiting the original function of the anti-skid and preventing it from coming off the tire. Also, during high-speed running, due to the elasticity limit of the anti-skid body 2 as well as the hook connecting portion 7A, the anti-skid body 2 does not lift from the tire outer periphery and may contact the tire housing. Absent.

When the tire slip stopper 1 is removed from the tire, the tightening of the tightening cord 12 by the tightening tool 15 is released and the engaging hook 14 is removed in the same manner as in the conventional case, and the link hooks 9, 9 of the connecting band portion 5, By removing 10, you can easily remove it. FIG. 2 shows a second embodiment of the present invention, which is different from the first embodiment only in the arrangement of the core material 8 and has substantially the same action and effect. That is, in the second embodiment, one strip of the core material 8 is provided from the center of the anti-skid body 2 in the width direction to the diagonal cross mesh portion 4 on the tire inner side, and from the connecting strip portion 5 at one end in the longitudinal direction to the other. After being arranged without intersecting toward the connecting belt portion 5, they are arranged in the diagonally crossed mesh portion 4 on the outer side of the tire without intersecting in the opposite direction.

In the second embodiment, not only the connecting portions 6A and 7A between the hooking portions on the tire inner side and the tire outer side but also the entire portion expands and contracts to absorb the looseness of the hooking portions 6 and 7 on both the inner and outer sides. Eccentricity, deviation, etc. can be corrected. FIG. 3 shows a third embodiment of the present invention, which is different from the first embodiment in that the ladder-like grounding portion of the main body 2 of the anti-skid device is eliminated and the whole is made into a diagonal cross mesh shape. Has the same effect as the example. Therefore, detailed description is omitted.
