Claims (6)
- モータ(17)により駆動可能な、工具のための往復駆動装置(20)を備えた手持ち鋸装置(10)であって、
前記往復駆動装置(20)には、前記モータ(17)により回転運動可能な偏心ギヤ(23)の第1偏心子(24)によって往復運動可能な往復体(21)と、前記偏心ギヤ(23)の第2偏心子(25)によって、軸線(A)に沿って逆向き往復運動可能なカウンタウェイト(22)と、を備え、
半径方向外方に延在する外周面(28)を備えた前記第2偏心子(25)は、内周壁(27)に囲まれた、前記カウンタウェイト(22)の開口(26)に係合し、前記外周面(28)と前記内周壁(27)との間の押し出し方向(D)には第1接触領域(41)、引き込み方向(Z)には第2接触領域(42)がそれぞれ存在する、該手持ち鋸装置(10)において、
前記開口(26)の前記内周壁(27)と、前記第2偏心子(25)の前記外周面(28)との間の少なくとも前記接触領域(41,42)に中間素子(30)を設け、
前記軸線(A)に平行に指向する、前記中間素子(30)の第1半径方向長さ(R1)を、前記軸線(A)に直交する方向に指向する、前記中間素子(30)の第2半径方向長さ(R2)よりも小さくしたことを特徴とした鋸装置。 - 請求項1記載の鋸装置において、前記中間素子(30)をリング状に構成し、その双方の接触領域(41,42)にそれぞれ円弧状の当接セグメント(31)を設け、これらの当接セグメント(31)は、その凹面(34)において、前記第2偏心子(25)の前記外周面(28)に形状規制的なロックを生ずるよう接触する構成とした、鋸装置。
- 請求項2記載の鋸装置において、前記円弧状の当接セグメント(31)は、10°〜40°の角度範囲(α)にわたり延在するものとした鋸装置。
- 請求項2または3記載の鋸装置において、前記円弧状の当接セグメント(31)は、20°〜30°の角度範囲(α)にわたり延在するものとした鋸装置。
- 請求項1〜4のうちいずれか一項に記載の鋸装置において、前記中間素子(30)は、ばね鋼から形成した鋸装置。
- 請求項2〜5のうちいずれか一項に記載の鋸装置において、前記中間素子(30)は、少なくとも各円弧状の当接セグメント(31)の領域に、前記内周壁(27)に接触する少なくとも2個の当接面(32)を有するものとした鋸装置。
