Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvement of an anti-slip body of a ladder-type tire anti-skid device having spike pins.

[0002]

[Prior art]

 Conventionally, the anti-slip body of this type of ladder-type tire anti-slip device has an anti-slip body body formed of rubber or the like in a desired width, and a thread made of high-tensile fiber provided inside the body in the width direction. A strip-shaped core material that is juxtaposed in parallel with each other and covered in a thin film with rubber, and the upper end is exposed on the surface of the main body and the lower end is positioned above the core material so that It was configured with spike pins that were installed.

[0003]

[Problems to be solved by the device]

 However, this kind of anti-slip body with spike pins is mounted on a tire to run on an icy road surface, and when the brakes are applied, the spike pins on the surface are caught on the icy road surface to enhance the breaking effect. At this time, a large force is applied to the spike pin in the direction opposite to the traveling direction (that is, backward when the brake is applied when moving forward), and the above-mentioned conventional technology cannot counter that force. However, there was a risk that the spike pin would fall out.

That is, in the above-mentioned conventional anti-slip body, although the core material is internally provided to suppress the extension of the main body of the anti-slip body, the core material is merely a yarn arranged side by side in the width direction to form a combed weave. Since it was not able to resist the force in the direction opposite to the traveling direction, that is, the extension force applied in the width direction, the rubber around the spike pin due to the force applied to the spike pin was not able to be resisted. The extension could not be suppressed and the spike pin would fall out due to the above force.

The present invention has been made in view of such problems of the prior art, and an object thereof is to prevent the spike pin from being pulled out.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the technical means made by the present invention is to provide a non-slip body having a desired width with a strip-shaped core material whose outer peripheral surface is covered with rubber, and to attach each end portion of the core material. Ladder type in which spike pins are inscribed by being wound around the winding parts of the hooks provided inside both ends of the main body, exposing the upper end on the surface of the main body, and positioning the lower end above the core material. In the non-slip body of the tire anti-skid device, a core material woven by high-tensile fiber threads arranged side by side in the width direction, and a core material laid in the length direction and formed by weave That is, the above-mentioned strip-shaped core material is configured by stacking a desired number of sheets.

[0007]

[Action]

 Therefore, even if the spike pin is caught on the frozen road surface when the vehicle runs on the frozen road surface and the brakes are applied, and even if a great force is applied to the spike pin in the direction opposite to the traveling direction, the spike pin is installed below the spike pin. The core material prevents the rubber around the spike pin from expanding in the width direction.

【Example】

 Hereinafter, one embodiment of the present invention will be described with reference to the drawings. In the figure, a represents a non-slip body of the present invention, and both ends of the non-slip body a are attached and fixed to both inner and outer connecting ropes 14, 14. By arranging a desired number of these anti-skid bodies a side by side at an appropriate interval, a ladder-type tire anti-skid device A having a ladder-like structure is formed.

The non-slip body a is composed of a non-slip body 1, a belt-shaped core member 6, hooks 9, 9 and spike pins 10, and the non-slip body 1 is made of natural or synthetic rubber. Alternatively, using synthetic resin (for example, polyurethane, polyvinyl chloride, etc.), the portions 4 and 4 that transition from the central portion 2 corresponding to the tire tread surface to the shoulder portions 3 and 3 on both ends are gently curved. The belt-like shape is formed to have an appropriate width, and in the present embodiment, the width of both end portions 5 and 5 is appropriately made larger than the width of the central portion 2 for illustration. There is.

That is, as described above, the ends 5, 5 are made wider than the central part 2 because the ends 5, 5 have a wider area and are closely attached to the tire side face. This is to increase the resistance to the twisting force in the direction 11.

The strip-shaped core material 6 is a core formed by arranging threads 13 made of high-tensile fiber such as polyester fiber, nylon fiber, glass fiber or metal fiber in the lengthwise direction 12 in a strip-shaped weave. The material 8 and the above-mentioned yarns 13 are arranged side by side in the width direction 11 and the core material 7 woven in the shape of a strip and woven in different directions 11 and 12 of different core materials 7 and 8 are appropriately combined and superposed. Each of the core materials 7, 7 and 8 is covered with rubber in a thin film shape, and the above-mentioned combination is formed by interlacing the core material woven in the width direction with the core material woven in the length direction. As long as it has a woven core material, the core material may be of two-layer, three-layer, or four-layer shape and is not limited in any way. Are placed one above the other, and interleaved with a core material 8 that is woven in the direction of 12 in the lengthwise direction, and is heavy-weighted. It has a three-layer structure.

Further, in this embodiment, the width of each of the core members 7, 7 and 8 is slightly narrower than the width of the non-slip body 1, and the lengths of the core members 7 and 7 are different from each other (the core members 7 and 7). , 7, the core material 8 has a short shape.

The reason why the widths of the respective core members 7, 7 are made closer to the width of the main body 1 is to increase the resistance against the twisting force in the width direction 11, and the lengths are made different. This is because the number of steps is reduced to enhance the adhesive force when the film is wound around the retaining metal fitting 9 which will be described later and is folded and bonded.

It should be noted that the above example is merely an example and is not limited in any way and is arbitrary. The strip-shaped core member 6 has its end portions 6a, 6a wound around the respective winding portions 9b, 9b of the respective retaining metal fittings 9, 9 and folded back to be adhered (wrapped) so that the non-slip body 1 is in a tensioned state. It is installed inside.

For example, as shown in the drawing, the latching metal 9 is formed by integrally connecting the upper ends of two side J-shaped latching portions 9a, 9a which are juxtaposed at appropriate intervals with one rod-shaped winding portion 9b. The upper end of the winding portion 9b is internally provided in the end portion 5 of the non-slip body 1, and the hook portions 9a, 9a are projected to the lower surface of the end portion 5. The end portions 6a, 6a of the strip-shaped core material 6 are wound around the respective winding portions 9b, 9b from the upper side or the lower end so as to be folded and adhered to be stretched in a tension state.

The spike pin 10 has a desired shape as shown in the drawing, and its lower end 10b is located above the surface 6b of the strip-shaped core member 6 provided inside the anti-skid body 1 and its upper end 10a. Are exposed on the surface 1a of the non-slip body 1 and are provided inside the anti-slip body 1 in a desired number, and the number and arrangement are arbitrary.

Therefore, the non-slip body a having the above-mentioned structure is attached to both of the inner and outer connecting ropes 14 and 14 which are juxtaposed at appropriate intervals, and the hooking portions 9a, 9a, 9a, 9a of the hooking metal 9, 9 at both ends. A ladder-type tire slip stopper A having a desired length is formed by hooking and disposing a desired number of slip stoppers a ... Then, when the tire B is mounted as shown in FIG. 3, the hooking metal fittings 9, 9 at both ends are pulled toward the center b of each of the inner and outer sides of the tire B, and the tread surface B ′ and the inner and outer side surfaces B of the tire B are pulled. The non-slip body 1 is brought into close contact along ", B".

At this time, the pulling force of the tire B toward the center direction b is also applied to the main body so as to make close contact with the tire B as described above. The strip-shaped core material 6 hung between the metal fittings 9 and 9 opposes the pulling direction to suppress the pulling force.

When the vehicle travels on an icy road surface and the brakes are applied, the spike pins 10 ... Hook on the icy road surface, and the spike pins 10 ... Reverse the traveling direction (the width direction indicated by 11 in the figure). Even if a great amount of force is applied to the spike pin 10, the strip-shaped core material 6 provided below the spike pin 10 ... suppresses the expansion of the rubber 11 around the spike pin 10 ... in the width direction 11, so that the spike pin 10 ... Will not fall out.

The anti-skid body a ′ shown in FIGS. 4 and 5 is applied to a ladder-type tire anti-skid device A ′ used for a double tire of a truck or the like, and shows another embodiment of the present invention. This is an example. Since the non-slip body 1'is formed in a substantially X-shape in plan view, it is the same as the above-mentioned embodiment, and therefore the same portions are designated by the same reference numerals and the description thereof is omitted.

[0021]

[Effect of device]

 Since the present invention has the structure as described above, the spike pin is attached to a frozen road surface when the tire is fitted with a ladder-type tire anti-slip device constructed by using a desired number of the anti-skid bodies of the present invention and the tire is run. Even if a large amount of force is applied to the spike pin in the direction opposite to the advancing direction, the strip-shaped core material that is internally provided below the spike pin is formed by arranging threads made of high-tensile fibers side by side in the width direction. It has a structure in which a core material woven in the shape of a blind and a core material woven in the shape of a blind which are arranged side by side in the lengthwise direction are stacked, and the band-shaped core material resists the force applied to the spike pins and the width of the non-slip body. Since the extension in the direction can be suppressed, the extension of the rubber around the spike pin can be suppressed, and as a result, there is no fear that the spike pin will be pulled out. Therefore, this type of anti-slip body can be effectively used for a long period of time and its durability can be improved, so that it has high commercial value.
