Abstract
Description
上記のような嵌め込み式の滑り止め装置においては、使用前に、滑り止め体は、自動車のタイヤの幅に応じて内幅を調整する。滑り止め体の内幅は、滑り止め装置の使用中、自動車の走行中、一定に維持される。
ところが、自動車のタイヤは、充填空気量や車体の積載重量の増減、走行中の車体から受ける力の変動などによって変形し、軸心方向の幅が変動する。タイヤは、滑り止め装置を装着した後でも、自動車の走行中でも、幅が増減する。
滑り止め体は、内幅の調整に多くの手間が掛らないことが望まれる。
嵌め込み式の滑り止め装置において、滑り止め体は、当て部材を弾性力でタイヤの側面に押し当てることにする。
タイヤの幅が減少し、当て部材が当たっているタイヤの側面が当て部材と反対側に移動すると、当て部材が弾性力でタイヤの側面側に前進する。逆に、タイヤの幅が増加し、当て部材が当たっているタイヤの側面が当て部材側に移動すると、当て部材が弾性力に抗して後退する。当て部材は、タイヤの側面の移動に応じて移動する。当て部材とタイヤ側面との接触が維持される。
具体的には、滑り止め体の外側部又は内側部に軸を滑り止め体の幅方向に沿って取り付ける。その軸は、滑り止め体の幅方向、タイヤの軸心方向に前後動可能にする。滑り止め体内に突出した軸の内端は、当て部材を設ける。当て部材付きの軸に前進力を与える弾性部材を設ける。
滑り止め体の外側部又は内側部に軸をタイヤの軸心方向に沿って取り付け、軸はタイヤの軸心方向に前後動可能にし、滑り止め体内に突出した軸の内端に当て部材を設け、当て部材付きの軸に前進力を与える弾性部材を設け、
当て部材を弾性部材の弾性力でタイヤの外側面又は内側面に押し当て、当て部材が当たっているタイヤの外側面又は内側面が当て部材と反対側に移動すると、当て部材が弾性部材の弾性力で前進し、当て部材が当たっているタイヤの外側面又は内側面が当て部材側に移動すると、当て部材が弾性部材の弾性力に抗して後退する構成にした。
2.上記1のタイヤの滑り止め装置において、
弾性部材は、螺旋ばねにし、軸の内端側部分に嵌合し、当て部材と滑り止め体の外側部又は内側部の間に嵌め込んだ。
3.上記2のタイヤの滑り止め装置において、
螺旋ばねは、竹の子ばねにし、最大収縮時に渦巻き形状になる構成にした。
4.上記2又は3のタイヤの滑り止め装置において、
滑り止め体外に突出した軸の外端に抜け止めを施し、軸の外端側部分に外側の調整板を嵌合し、外側の調整板を抜け止めと滑り止め体の外側部又は内側部の間に嵌め込んだ。
5.上記2、3又は4のタイヤの滑り止め装置において、
軸の内端側部分に内側の調整板を嵌合し、内側の調整板と螺旋ばねを当て部材と滑り止め体の外側部又は内側部の間に嵌め込んだ。
本例のタイヤの滑り止め装置は、自動車のタイヤTに装着した状態を自動車の外側から視た正面図を図1に示す。自動車の外側になる部分は実線で、内側になる部分は破線で示す。滑り止め装置は、図1に矢印で示す自動車前進時のタイヤTの正回転方向の前側から順に、第1滑り止め体1a、第2滑り止め体1bと第3滑り止め体1cをタイヤTの周方向に等間隔に配置して連結している。
本例のタイヤの滑り止め装置は、図10と図11に示すように、滑り止め体1を第1滑り止め体1aと第2滑り止め体1bの2個にしている。2個の滑り止め体1a、1bは、帯状に連結している。滑り止め体1a、1bは、前側のU形状部材2と後側のU形状部材3の構成を変更している。当て部材6の取付構造を変更している。
その他の点は、第1例におけるのと同様である。第1例におけるのと同様な部分には、図中、第1例におけるのと同一の符号を付ける。
本例のタイヤの滑り止め装置は、図12に示すように、第1例又は第2例における当て部材6付き軸7に前進力を与える弾性部材を、円筒形状の螺旋ばね9に替えて、円錐台筒形状の螺旋ばね、竹の子ばね42にしている。
その他の点は、第1例又は第2例におけるのと同様である。
本例のタイヤの滑り止め装置は、図14と図15に示すように、第3例における当て部材6の取付構造に調整板43、44を追加している。
その他の点は、第3例におけるのと同様である。第3例におけるのと同様な部分には、図中、第3例におけるのと同一の符号を付ける。
1.上記の実施形態において、外側と内側の両側の当て部材6は、タイヤTの外側面又は内側面の移動に応じて移動可能にしているが、外側又は内側の片側のみの当て部材6を移動可能にする。
2.上記の実施形態において、当て部材6の取付構造は、当て部材6付き軸7に前進力を与える弾性部材に、円筒形状や円錐台筒形状の螺旋ばね9、42を用いているが、その他の弾性部材を用いる。
3.上記の実施形態の第4例において、外側と内側の調整板43、44は、円輪板形状にしているが、馬蹄形状やその他の形状にする。
4.上記の実施形態において、当て部材6の取付構造は、軸7の抜け止めに割ピン8を用いているが、ロックナットや止め輪などのその他の抜け止め手段を用いる。
5.上記の実施形態において、当て部材取付部材は、第1例においてはU形状部材2、3にし、第2例においてはU形状部材2、3に取り付けた部材16~19、41にしているが、内側の線状部材4、前側の連結部材11、後側の連結部材12や線状の連結部材5にする。
