Description

【0001】
【発明の属する技術分野】
本発明は空気入りタイヤに関するもので、特に、サイドウォールの表面に、周方向に小さな間隔を置いて設けられた多数の小さなリッジよりなる環状の装飾体を備えた空気入りタイヤに関するものである。
【0002】
【従来の技術】
従来、周方向に微小間隔を置いて設けられた多数のリッジよりなる環状の装飾体をサイドウォールの表面に備えた空気入りタイヤでは、リッジの間隔が周上等間隔であった。
【0003】
【発明が解決しようとする課題】
一般に、タイヤのサイドウォールの表面には、文字、数字、記号又は図形などよりなるトレードマークやトレードドレスなどの標章の他に、規格に基づき多くの文字やマーキングを備えることが義務づけられている。そこで、限られたスペースの中に多くの文字、数字、記号又は図形などをレイアウトしても、これらの文字などの視認性が高いことが要請されている。
【0004】
本発明の目的は、サイドウォールの表面に周方向に小さな間隔を置いて設けられた多数の小さなリッジよりなる環状装飾体を備えた空気入りタイヤにおいて、この環状装飾体の上に設けられた、文字、数字、記号又は図形などよりなるトレードマークやトレードドレスなどの標章の視認性が優れているタイヤを提供することである。
【0005】
【課題を解決するための手段】
本発明は、タイヤのサイドウォールの表面に、環状の装飾体を備えた空気入りタイヤにおいて、該装飾体は、タイヤの子午線に対して0乃至80度程度の傾斜角度で同じ方向に直線状に延びる、高さが0.2乃至2.5mmのリッジを、周方向に0.4乃至5mmの間隔にて多数配列し、かつリッジ上に、文字、数字、記号又は図形などの標章を、その表面がリッジ表面よりタイヤの外側に少なくとも0.1mm突出させて配置してなり、さらに装飾体は、多数のリッジを隣接相互間でほぼ平行にかつ等間隔に配列した第一領域と、多数のリッジを、第一領域のリッジ密度と異なるリッジ密度で配列した第二領域との、それぞれ単数または複数の組み合わせであり、第二領域の周方向長さが第一領域の周方向長さに比べて短いことを特徴とする多数のリッジによる装飾体を備えた空気入りタイヤである。
【0006】
ここで、装飾体のリッジのタイヤの子午線に対する傾斜角度とは、装飾体のラジアル方向内側端部における、タイヤ子午線に対するリッジの傾斜角度である。換言すれば、ラジアル方向内側から外側に向かって直線状に延びているリッジのラジアル方向内側端部における、リッジとタイヤの子午線との角度である。
【0007】
なお、装飾体の第一領域の表面に設けられた多数のリッジのすべてが、タイヤの子午線に対し一定の方向に直線状に延びているので、厳密に言えばリッジは隣接するリッジと平行に延びているとは言えない。けだし、リッジは隣接するリッジと「ほぼ平行に」直線状に延びると表現されて所以である。
【0008】
また、上記目的を達成するために、本発明による空気入りタイヤでは、
(1) 第二領域のリッジ密度が第一領域のリッジ密度より低いこと、
(2) 第二領域のリッジが不等間隔配列であること、
(3) 第二領域の周方向長さは、装飾体の全周長さの1乃至25%であること、
(4) 装飾体は1乃至6個、とりわけ2乃至4個の第二領域を含むこと、
(5) 第二領域の周方向長さの総和が装飾体の全周長さの1乃至25%であること、
(6) 第二領域内のリッジ密度が周方向に順次変化すること、
(7) 標章が装飾体と同心円状に設けられていること、
(8) リッジの表面がサイドウォールの表面(仮想面)よりタイヤの内側に位置していること、
(9) 標章の表面がサイドウォールの表面(仮想面)よりタイヤの外側に位置していること、そして
(10)標章の表面がフラットであること、
が好ましい。
【0009】
【発明の実施の形態】
本発明による空気入りタイヤは、上述のように、装飾体のリッジ密度が第一領域と第二領域とで異なっているため、リッジの粗密によって光線の反射が微妙に変化し、リッジ上に設けられた文字、数字、記号又は図形などの標章が視覚上認識し易くなる。
【0010】
また、本発明による空気入りタイヤでは、
(1) 第二領域のリッジ密度が第一領域のリッジ密度より低いこと、
(2) 第二領域のリッジが不等間隔配列であること、
(3) 第二領域の周方向長さは、装飾体の全周長さの1乃至25%であること、
(4) 装飾体は1乃至6個、とりわけ2乃至4個の第二領域を含むこと、
(5) 第二領域の周方向長さの総和が装飾体の全周長さの1乃至25%であること、
(6) 第二領域内のリッジ密度が周方向に順次変化すること、
(7) 標章が装飾体と同心円状に設けられていること、
(8) リッジの表面がサイドウォールの表面(仮想面)よりタイヤの内側に位置していること、
(9) 標章の表面がサイドウォールの表面(仮想面)よりタイヤの外側に位置していること、そして
(10)標章の表面がフラットであること、
によって、標章が視覚上さらに認識し易くなる。
【0011】
