Description

【０００１】
【産業上の利用分野】
この発明は、雪路や凍結路を自動車で走行する際に、タイヤがスリップしないようにタイヤに巻いて使用するタイヤの滑り止め具に関するものである。
【０００２】
【従来の技術】
従来のタイヤの滑り止め具としては、金属製の鎖を梯子形に連結したものが一般に良く知られている。しかし、この従来のタイヤの滑り止め具は、鎖を梯子形に連結したものであるため走行時に上下の振動が発生したり、鎖が路面に当たって騒音が生ずるなど乗り心地が悪いだけでなく、金属製であることから重量が重いという問題点があった。
【０００３】
そこで、このタイヤの滑り止め具に代わるものとして、特開昭６１−５４３０７号のように、可撓性合成樹脂材からなる滑止片を複数枚帯状に連結した重量の軽いものが開発された。
【０００４】
この開発された滑り止め具は、それぞれの滑止片どうしを、滑止片がタイヤのサイドウォール部に当接する部分で連結するようにしたものであるので、滑り止め具の装着位置が正規の位置からずれた場合には、滑止片の端部がタイヤのトレッド部に密着せずに浮き上がり、振動や騒音の原因となるという問題点があった。
【０００５】
【発明が解決しようとする課題】
この発明は、上記従来の問題点を解決するためになされたもので、重量が軽く、しかも滑り止め具の装着位置が正規の位置から多少ずれた場合でも、滑止片の端部がタイヤのトレッド部に密着して浮き上がらないようにしたタイヤの滑り止め具を提供することを課題とするものである。
【０００６】
【課題を解決するための手段】
そのため、この発明では、それぞれ可撓性合成樹脂材からなる左側の滑止片１、中央の滑止片２、右側の滑止片３を帯状に連結してなるタイヤの滑り止め具であって、左側の滑止片１は、輪郭形状が三角形の左側部１１と輪郭形状が菱形の中央部１２及び右側部１３からなり、中央の滑止片２は、輪郭形状が菱形の左側部２１、中央部２２及び右側部２３からなり、右側の滑止片３は、輪郭形状が菱形の左側部３１及び中央部３２と、輪郭形状が三角形の右側部３３からなり、左側の滑止片１において、左側部１１のタイヤの裏側のサイドウォールに当接する部分に、右側に短絡片１６が形成されており、滑止片１の右側部１３のタイヤの裏側のサイドウォールに当接する部分に、左側に短絡片１６ａ、右側に短絡片１６ｂが形成されており、左側部１１の右側の短絡片１６が中央部１２の端１７と、右側部１３の左側の短絡片１６ａが中央部１２の端１７と、右側部１３の右側の短絡片１６ｂが中央の滑止片２の左側部２１の端２７と連結され、さらに左側の滑止片１の右側端は幅方向中央で幅狭になっており、中央の滑止片２との連結部１８となっており、中央の滑止片２において、中央部２２のタイヤの裏側のサイドウォールに当接する部分に、左側に短絡片２６、右側に短絡片２６ａが形成されており、左側の短絡片２６が左側部２１の端２７と、右側の短絡片２６ａが右側部２３の端２７ａと連結され、さらに中央の滑止片２の左側端は左側の滑止片１との連結部２８となっており、中央の滑止片２の右側端は右側の滑止片３との連結部２８ａとなっており、これら連結部２８、２８ａは幅方向中央で幅狭になっており、右側の滑止片３において、左側部３１のタイヤの裏側のサイドウォールに当接する部分に、左側に短絡片３６、右側に短絡片３６ａが形成されており、滑止片３の右側部３３のタイヤの裏側のサイドウォールに当接する部分に、左側に短絡片３６ｂが形成されており、左側部３１の左側の短絡片３６が中央の滑止片２の右側部２３の端２７ａと、左側部３１の右側の短絡片３６ａが中央部３２の端３７と、右側部３３の左側の短絡片３６ｂが中央部３２の端３７と連結され、さらに右側の滑止片３の左側端は幅方向中央で幅狭になっており、中央の滑止片２との連結部３８となっているタイヤの滑り止め具とした。上記構成とすれば、滑り止め具の装着位置が正規の位置からずれた場合でも、滑止片１、２、３の端部がタイヤのトレッド部に密着して浮き上がらなくなる。また、滑り止め具が多少正規の位置からずれて曲がってタイヤに装着された場合でも、連結部分で曲がりやすくなっているので、滑止片１、２、３がタイヤのトレッド部に密着しやすくなる。
【０００８】
前記滑止片１，２，３どうしは、滑止片１，２，３の連結部18,28,28a,38の裏側両面に渡って当てられた裏当金６と、裏当金６と滑止片１，２，３を締結する鋲により連結することが好ましい。

このとき、滑止片１，２，３の位置がタイヤのトレッド部の所定の位置から多少ずれて装着されても、滑止片１，２，３の端部どうしが幅方向略中央位置で連結されているので、滑止片１，２，３がタイヤのトレッド部に密着し、振動や騒音が発生することがない。
【００２１】
図６は、滑止片１と滑止片２、及び滑止片２と滑止片３の接続部18,28,28a,38の別の実施例である。
【００２２】
この実施例では、接続部18,28,28a,38の裏側に当てられた裏当金６を、タイヤの周方向に向けて配置して滑止片を連結する代わりに、タイヤの幅方向に向けて配置して滑止片を連結した例である。このとき、滑止片の一方の接続部18,28aに凸部と凹部を形成し、対応する接続部28,38 に前記凸部と凹部と嵌合する凸部と凹部を形成し、その裏側に裏当金６を当て、裏当金６と滑止片をスパイクピン10により締結して連結したものである。このように、接続部の裏当金６の配置は、任意に変更することができる。
【００２３】
【発明の効果】
この発明のタイヤの滑り止め具は、滑止片１，２，３が合成樹脂材で形成されているため重量が軽い、しかも滑り止め具の装着位置が正規の位置からずれた場合でも、滑止片１，２，３の端部がタイヤのトレッド部に密着して浮き上がらなくなっているので、振動や騒音が少なく乗り心地のよいものとなる。
【００２４】
請求項２記載の発明では、請求項１記載の構成に加え、滑止片１，２，３どうしを連結する連結部18,28,28a,38を幅狭形状に形成しており、連結部分で曲がりやすくなっているので、滑止片１，２，３がタイヤのトレッド部に密着しやすくなっている。そのため、より振動や騒音が少なく乗り心地のよいものとなるという効果が生ずる。
【００２５】
前記滑止片１，２，３どうしは、滑止片１，２，３の連結部18,28,28a,38の裏側両面に渡って当てられた裏当金６と、裏当金６と滑止片１，２，３を締結する鋲により連結することが好ましく、前記構成とすることにより、連結部の強度が増した耐久性に優れたものとなる。
【００２６】
前記鋲を頭部に突起10a を形成したスパイクピン10とすれば、駆動力が増し、雪道での走破性が優れたものになるという効果が生ずる。

This is an example in which the anti-slip pieces are connected to each other. At this time, a convex portion and a concave portion are formed in one connection portion 18, 28a of the anti-skid piece, and a convex portion and a concave portion that are fitted to the convex portion and the concave portion are formed in the corresponding connection portion 28, 38, and the back side The backing metal 6 is applied to the back, and the backing metal 6 and the non-slip piece are fastened and connected by the spike pin 10. In this way, the arrangement of the backing metal 6 of the connecting portion can be arbitrarily changed.

【The invention's effect】
The anti-skid tool of the tire according to the present invention is light in weight because the anti-skid pieces 1, 2 and 3 are formed of a synthetic resin material, and even when the anti-skid tool mounting position deviates from the normal position, Since the end portions of the stop pieces 1, 2 and 3 are in close contact with the tread portion of the tire and do not float, the vibration and noise are reduced and the ride quality is improved.
[0024]
In the invention described in claim 2, in addition to the structure described in claim 1, the connecting portions 18, 28, 28a, 38 for connecting the antiskid pieces 1, 2, 3 are formed in a narrow shape, Therefore, the anti-slip pieces 1, 2 and 3 are easily adhered to the tread portion of the tire. Therefore, there is an effect that the vibration and noise are reduced and the ride quality is improved.
[0025]
The anti-skid pieces 1, 2, 3 are connected to a backing metal 6 that is applied over both sides of the connecting portions 18, 28, 28 a, 38 of the anti-skid parts 1, 2, 3, It is preferable to connect the antiskid pieces 1, 2, and 3 with a hook that fastens, and by adopting the above-described configuration, the durability of the connecting portion is increased and the durability is excellent.
[0026]
If the spear is a spike pin 10 having a projection 10a on the head, the driving force is increased, and the effect of running on a snowy road is excellent.
