Abstract
Description
使用者が背もたれA2が姿勢を後方傾斜する時、該背もたれA2に加えた力が2つの駆動部材12を回転角度の変化を発生させ、ベース1のガイド孔13に合わせて第2支軸14の変位の裕度の設計を提供し、シートA3を同期して背もたれA2の方向へ延伸させることもできる(図7参照)。同時に、該2つの駆動部材12は、第1支軸12を支点とし、プルロッド3の背もたれA2の方向への運動を回転連動し、該プルロッド3と接続するフレーム31の作用端311にバネ4に対して施圧させ、変形を発生して背もたれA2に弾性力の支持を獲得させる(図8参照)。このような設計は、使用者が背中を寄せて後方傾斜する時にたるみを感じさせず、快適に感じさせるだけでなく、更に、重要なこととして、前記先行技術に比較して、該バネ4を押圧する作用力は、該第1支軸12からフレーム31までの作用端311のパワーアームの長さを増加し、背もたれA2の後方傾斜が発生する回転トルクも相対的に向上させ、更に省力にバネ4を圧縮する抵抗力を克服させることができる。

Claims (5)
- 椅子のシート下方に取り付けられ、背もたれと連動される背もたれ後方傾斜の弾力支持装置であって、
一端が背もたれの2つの相対側にそれぞれ接続する一対の駆動部材と、
該2つの駆動部材と対応し、第1支軸によって相互にピボット接続し、相互の回転を支持可能にさせる一対の仕切り板を有するベースと、
該ベースに設置されるバネと、
該ベースに跨り、その軸方向の二端が、それぞれ2つの駆動部材の自由端に接続し、上部にバネを包囲するフレームを環状に接続し、該フレームがバネに当接する作用端を有するプルロッドと、
を含み、背もたれが受力して後方傾斜する時、該2つの駆動部材を連動してトルクを発生してプルロッドの背もたれの方向への運動を牽引させ、同時にフレームの作用端を連動してバネを押圧してバネに受力変形させて該背もたれに弾性力の支持を獲得させる背もたれ後方傾斜の弾力支持装置。 - 前記2つの仕切り板は、該駆動部材から離れる他端にそれぞれガイド孔を設け、該ガイド孔中にシートの底部に接続する第2支軸を設け、且つ該ガイド孔は、該第2支軸をその中で変位させるように支持し、該2つの駆動部材の一端は、それぞれ第3支軸によってシートの底部とピボット接続し、背もたれを後方傾斜させた時にシートを連動可能にさせる請求項1に記載の背もたれ後方傾斜の弾力支持装置。
- 前記ベース上においてプルロッドを安置させる位置に合わせてそれぞれ限位溝を設け、該プルロッドの二端部を該2つの限位溝中に置かせて位置決めを獲得させ、該限位溝の幅がプルロッドの径よりも大きく、該プルロッドに変位可能な十分な裕度を持たせ、該2つの駆動部材の自由端箇所にプルロッドをフックするフック部材を設ける請求項1又は2に記載の背もたれ後方傾斜の弾力支持装置。
- 前記フレームの作用端は、貫通孔を有し、シャフトを通過させるようにベース中に設け、前記バネは、該シャフトの外部にスリーブ接続して作用時の支持を獲得し、該シャフトの一端に押圧プレートを接合するねじ山を設け、該押圧プレートは、バネの一端に当接する請求項1又は2に記載の背もたれ後方傾斜の弾力支持装置。
- 前記シャフトの他端は、受動ギアを設け、該ベース上に駆動ロッドを環状に接続し、該駆動ロッドの一端にシャフト上の受動ギアと噛み合う駆動ギアを設ける請求項4に記載の背もたれ後方傾斜の弾力支持装置。
