Description
後端に非円形または多角形の窪みの形状の形状適合要素56を有するアジャスタ装置50を通して、そのアジャスタ装置50の変位により、および、したがって、ねじ駆動部を介して軸方向に調整可能な弁ばねホルダ60の変位により、ピストンロッド140を介するばねの予張力の手動調整を達成することができる。回転の方向に応じて、ばね30は緩められるかまたは引っ張られる。屈曲運動における油圧ダンパ100の作動の過程で、屈曲室100において過負荷ピークが発生する場合、弁体30がばね30のばね力に抗して弁座10から押し出され、弁座10から押し出されることにより弁1が開き、これにより通路40が開通して、油圧流体が流路(図示せず)を介して屈曲室131から伸長室132内に流れることができる。伸長運動において高圧が生じた場合に弁1を制御された方法で開くことができるように、屈曲室131および伸長室132を周囲で変更することも原理的には可能である。予張力ばね30の調整可能能力のおかげにより、一方では、弁体20の開放圧力をより正確に調整することができ、他方では、使用中の予張力を様々な活動、様々な歩行状況、または整形外科用装置の使用者の変化に合わせて調整し、対応する調整を実現することができる。
以下に、本願出願の当初の特許請求の範囲に記載された発明を付記する。
[1]油圧ダンパと、
弁座(10)を有し、予張力を付与された弁ばね(30)を介して前記弁座(10)の方向に閉鎖力を受ける弁体(20)を有する弁(1)と、
前記油圧ダンパと前記弁座(10)との間の流体接続(40)と、
を具備し、
前記弁(1)は、前記弁ばね(30)に付与された前記予張力を調節するためのアジャスタ装置(50)を備えていることを特徴とする整形外科用装置。
[2]前記アジャスタ装置(50)は、ねじ付ドライブを有することを特徴とする[1]に記載の整形外科用装置。
[3]前記アジャスタ装置(50)は、前記弁ばね(30)に結合され、ハウジング(70)内に取り付けられた弁ばねホルダ(60)を有し、前記弁ばねホルダ(60)上に形成され、前記ハウジング(70)内に配置された第2のねじ山(75)と係合する第1のねじ山(65)を有することを特徴とする[2]に記載の整形外科用装置。
[4]前記弁体(20)上の前記予張力は、無段階に調節可能であることを特徴とする[1]乃至[3]のいずれか1に記載の整形外科用装置。
[5]前記アジャスタ装置(50)は、設定マーキング(55)を有することを特徴とする[1]乃至[4]のいずれか1に記載の整形外科用装置。
[6]前記アジャスタ装置(50)は、該アジャスタ装置(50)を作動させることができる形状適合要素(56)を有することを特徴とする[1]乃至[5]のいずれか1に記載の整形外科用装置。
[7]前記アジャスタ装置(50)は、電動ドライブ(80)と、前記電動ドライブ(80)を制御する目的のために前記電動ドライブ(80)に結合されたコントローラ(85)と、を備えていることを特徴とする[1]乃至[6]のいずれか1に記載の整形外科用装置。
[8]前記整形外科用装置は、コントローラ(85)に結合された操作要素(90)を有し、および/または、前記電動ドライブ(80)を作動させるための通信インターフェース(91)を有することを特徴とする[7]に記載の整形外科用装置。
[9]前記整形外科用装置は、前記コントローラ(85)に結合された少なくとも1つのセンサ(95)を有することを特徴とする[7]または[8]のいずれか1に記載の整形外科用装置。
[10]前記コントローラ(85)は、少なくとも1つのセンサ値に従って前記ばねの前記予張力を調節するように構成されることを特徴とする[9]に記載の整形外科用装置。
[11]前記コントローラ(85)は、少なくとも1つのセンサ(95)によって体重および/またはユーザの動きのパラメータの値を決定し、1つまたは複数の決定された値から、前記ドライブ(80)の少なくとも1つの制御パラメータを算出するため、および前記弁ばね(30)の前記予張力を調節するために、前記ドライブ(80)を自動的に起動することを特徴とする[10]に記載の整形外科用装置。
