Description
(1)上方を向く筒状の肘掛け支柱の上端部内に、前後いずれか一方の内面に斜め上方に開口する上下複数段の係止溝を備える筒状の高さ調節部材を嵌着し、該高さ調節部材内に、上端に肘当てが取付けられた肘当て支持杆を上下に摺動可能に嵌合するとともに、該肘当て支持杆に、前記係止溝と選択的に係脱可能な停止部材を設けてなる椅子の肘掛け装置において、前記高さ調節部材を、それを左右に2等分する中心線に対し、左右いずれか一方に偏倚する位置において、長手方向に沿って左右に2分割構造とし、かつ分割された左右寸法の大きい一方の半筒状片に、前記係止溝を設ける。
また、高さ調節部材を、それを左右に2等分する中心線に対し、左右いずれか一方に偏倚する位置において、長手方向に沿って左右に2分割構造とし、かつ分割された左右寸法の大きい一方の半筒状片に、係止溝を設けているので、高さ調節部材を大径としなくても、係止溝の左右寸法を大とすることができ、それに合わせて停止部材の左右寸法も大きくしうるので、肘当てに加わる荷重に対しての強度を高めることができるとともに、肘掛け支柱を小型化しうる。
また、左右の半筒状片を180°向きを変えるだけで、停止溝の位置を前後いずれかに簡単に変更することができる。
図1は、本発明の肘掛け装置の中央縦断側面図、図2は、同じく、肘当てを上昇させたときの中央縦断側面図、図3は、同じく分解斜視図である。
従って、肘当て(4)の水平(左右)方向の位置を、停止溝(56)の数だけ段階的に調節することができる。
なお、上記肘当て(4)を下向させる際、自重により急速に下降するのを防止し、下限位置で停止したときの衝撃を緩和するために、ガイド溝(15)における後部の縦溝(15b)の幅を、ガイドピン(23)が適度の摩擦力をもって摺動しうる寸法としたり、縦溝(15b)の内面にゴム等の摩擦シートを貼着するなどしてもよい。

Claims (4)
- 上方を向く筒状の肘掛け支柱の上端部内に、前後いずれか一方の内面に斜め上方に開口する上下複数段の係止溝を備える筒状の高さ調節部材を嵌着し、該高さ調節部材内に、上端に肘当てが取付けられた肘当て支持杆を上下に摺動可能に嵌合するとともに、該肘当て支持杆に、前記係止溝と選択的に係脱可能な停止部材を設けてなる椅子の肘掛け装置において、
前記高さ調節部材を、それを左右に2等分する中心線に対し、左右いずれか一方に偏倚する位置において、長手方向に沿って左右に2分割構造とし、かつ分割された左右寸法の大きい一方の半筒状片に、前記係止溝を設けたことを特徴とする椅子の肘掛け装置。 - 係止溝を、分割された一方の半筒状片の左右方向のほぼ中央部に設けた請求項1記載の椅子の肘掛け装置。
- 高さ調節部材の前部と後部の分割位置を、高さ調節部材を中心として点対称をなすように左右方向にずらしてなる請求項1または2記載の椅子の肘掛け装置。
- 係止溝の分割面側の側端を、分割面に開口させるとともに、該開口された係止溝の側端を、分割された高さ調節部材の他方の半筒状片の対向面により閉塞するようにした請求項1〜3のいずれかに記載の椅子の肘掛け装置。
