Abstract
Description
この種の椅子は、着座者が作業を進める上で心地良いと感じた動作が可能なように、着座者の後傾動作に応じて座や背凭れが傾動し得るように構成されていたり、着座者の所要の姿勢が実現され得る位置に座および背凭れを固定し得るように構成されたりし、バネ反力を適切に設定できるように工夫されている。
一方、近時においてデスクワークの効率や適切な姿勢を高めるために、座が後方のみならず前方へ移動するような所謂揺れる椅子も検討されつつある。このような椅子を実現しようとする場合、従来の反力機構を用いると座が前端に達しても背の反力機構が働く構成となり、基準位置を境に前後に揺れて再び基準位置に戻るような機能は実現できない。このため、このような機能を実現するためには、新たに何らかの構造を創出することが求められる。
<第2実施形態>
2…座
4…第1の復帰力発生機構(前後方向)
40、41、42…弾性部材
5…第2の復帰力発生機構(左右方向)
Claims (11)
- 座が移動可能な範囲内で、前後方向の中間位置に基準位置を有するものであって、
前記基準位置から少なくとも前後方向に移動した座を前記基準位置へ戻す方向の復帰力を発生させる復帰力発生機構を備え、
前記復帰力発生機構が、前記基準位置からの移動量が大きくなるにつれて前記基準位置へ戻す方向の復帰力を大きくする弾性部材を有することを特徴とする椅子。 - 前記基準位置は、前後の移動可能範囲の中間にあって、人が着座していないときの位置であり、前記基準位置で前後方向の弾性力が0または釣り合うことで座が静止している請求項1記載の椅子。
- 前記復帰力発生機構が、弾性付勢力を変更可能に調整され得るものである請求項1又は2の何れかに記載の椅子。
- 座が基準位置よりも前方に位置しているときに基準位置方向に弾性付勢力を作用させる弾性部材と、座が基準位置よりも後方に位置しているときに基準位置方向に弾性付勢力を作用させる弾性部材とを各々有している請求項1〜3の何れかに記載の椅子。
- 座が基準位置よりも前方に位置しているときに基準位置方向に弾性付勢力を作用させるものと、座が基準位置よりも後方に位置しているときに基準位置方向に弾性付勢力を作用させるものを単一の弾性部材によって実現している請求項1〜3の何れかに記載の椅子。
- 弾性部材の初期変位量を変更することで弾性付勢力を変更調整可能とした請求項1〜5の何れかに記載の椅子。
- 弾性部材の初期位置を変更することで座の変位に伴う弾性部材の変位量を変え、弾性部材の反発力特性を調節変更可能とした請求項1〜5の何れかに記載の椅子。
- 弾性部材の初期変位量または初期位置を変更することで、前記基準位置が移動するように構成されている請求項1〜5の何れかに記載の椅子。
- 座の後方に背を有し、背座が共に前後方向に連動して移動可能なものであって、
移動量に応じて座の移動方向先端側が下方に傾斜することを特徴とした請求項1〜8記載の椅子。 - 座は、互いに独立した前後移動機構と左右移動機構によって支持されて、前後及び左右に移動可能に構成されており、左右方向にも独立した復帰力発生機構を備えていることを特徴とする請求項1〜9の何れかに記載の椅子。
- 左右の復帰力発生機構が、基準位置からの前記座の動作に伴い前記座の重心が上昇することを特徴とする請求項10記載の椅子。
