Abstract
Description
(1)背凭れの左右両側部の前後両面に、後方および前方に向かって凹入する上下方向を向く凹溝を設け、前記凹溝に、オプション部材の両側部に設けた取付部材の一部を係合させて、オプション部材を前記背凭れに取り付ける。
また、オプション部材を取り外した後に、ねじ孔等の取付構造の一部が残らないので、背凭れの外観を美麗に保つことができる。
図1~図3に示すように、この椅子は、先端部にキャスタ1を備える放射状をなす5本の脚杆2を有する脚体3を備えている。脚体3の中央には、ガススプリング(図示略)を備える伸縮式の脚柱4が立設されており、脚柱4の上端には、支基5の後部が固着されている。
この背凭れ支持杆9、9の前端部は、左右方向の軸10をもって支基5に枢着され、支基5の後端部と連結板8とに前後の端部が連結されたガススプリング11(図1参照)の作用により、背凭れ支持杆9、9と背凭れ6とは、軸10を中心として、前後方向に回動したり、所望の後傾角度で停止させられたりし得るようになっている。
背板13の上半部13aは、両側杆12、12の前縁寄りに、同じく下半部13bは、両側杆12、12の後縁寄りに接合し、それらの中間には、水平の段差部(図示略)が形成されている。
この両側杆12、12と背板13とは、弾性を有する硬質合成樹脂材料により、一体成形して形成するのが好ましい。
また、背板13の下半部13bの前面両側部には、剛性を高めるための多数のリブ15が設けられている。
さらに、前覆い板16の前面と、背板13の上半部13aの前面と、背板13の上半部13aの後面とは、二つ折りにしたクッション材17により覆われている。
なお、上下の閉塞片18a、18b、19a、19bのいずれか一方を省略することにより、凹溝18、19の上端および下端のいずれか一方を上方または下方に開放しておいてもよい。
なお、この凸部20に代えて、下端面が水平をなす側面視三角形の複数の凹部(図示略)としてもよい。
すると、係合爪24が、当接片25cの前下端か、または包囲片23の前部の下端内縁を支点とし、前方に回動させられて、凸部20から前方に離脱する。
この状態で、ハンガー21全体を上方または下方に移動し、係合爪24を、上下いずれかの別の凸部20に係合させればよい。
ハンガー21を上方に移動させる際は、ハンガー21を元の後傾姿勢に戻しつつ上昇させても、係合爪24は、上方の凸部20における前上方に傾斜する下縁に乗り上がって、一旦前方に押動された後、その凸部20の上面に係合することができる。
この例では、上部フレーム28を、背面視において、上方に円弧状に湾曲させ、また、補助フレーム29を、背面視において、下方に円弧状に湾曲させ、上部フレーム28と補助フレーム29との左右の両端部同士を、左右の傾斜起立フレーム27、27の上端部に、互いに結合するようにして連設してある。
また、オプション部材を取り外した後に、ねじ孔等の取付構造の一部が残らないので、背凭れの外観を美麗に保つことができる。
さらに、機能の異なる種々のオプション部材を、単独で、または複数個を組み合わせて、背凭れに装着することにより、椅子を多様化することができる。
(1) 各側杆12に、前後の凹溝18、19のうちのいずれか一方のみを設け、他方を省略し、設けた方の凹溝18または19に、取付部材22の係合爪24を嵌合し、側杆12における凹溝を設けていない方の前後いずれかの面に、弾性部材25における弾性舌片25bと当接片25cとを圧接し、係合爪24と、弾性部材25における弾性舌片25bおよび当接片25cとにより、各側杆12を前後から挾圧把持することにより、ハンガー21を支持するようにする。
