Abstract
本発明は鋸身全体の鋸歯を有効に利用し、より円滑な切断作業を行うことができるカーブソーを実現する。
【解決手段】
鋸身1は基部から先方に向けて湾曲させる。湾曲させた鋸身1の凹弧状側縁に多数の鋸歯2を形成し、鋸身1の基部に位置する鋸歯2の基方側縁である切れ刃3と鋸歯2の刃先4を結ぶ刃先線5との交差角度αを大きく、鋸身1の先方部に位置する鋸歯2の基方側縁である切れ刃3と鋸歯2の刃先4を結ぶ刃先線5との交差角度αを小さく形成する。これにより、鋸身の基部から先方部まで全体の鋸歯を有効に利用し、一定の力で円滑に切断作業を進めることができる鋸、主として剪定鋸を実現することができる。
【選択図】 図1
Description
引用文献1には、刃先線の曲率半径の中心線と鋸歯の裏刃、すなわち切れ刃との交差角度が、手元側から先端側へ行くに従って徐々に小さな角度となるように位相変化させた曲刃鋸(カーブソー)の思想が開示されている。この思想は、鋸身の先端側では切断対象物に対する引っ掛かりが悪くなるのを防止するという認識に基づいている。
このような実情に鑑み、本発明は鋸身全体の鋸歯を有効に利用し、より円滑な切断作業を行うことができるカーブソーを実現することを目的とするものである。
図1は本発明に係るカーブソーの鋸身全体の正面図、図2は鋸身の基部における切断状況を示す断面図、図3鋸身の先方部における切断状況を示す断面図である。
図5には、長い柄7の先端に鋸身1を固定した高枝剪定鋸を示しているが、この鋸によって被切断物Aである枝を切断する場合、鋸身1全体が上下方向に往復移動し、被切断物Aは鋸身の基部に位置する鋸歯と先方部に位置する鋸歯との間を往復して切断作業が進行する。
Claims (3)
- 基部から先方に向けて湾曲する鋸身の凹弧状側縁に多数の鋸歯を形成し、鋸身の基部に位置する鋸歯の基方側縁である切れ刃と鋸歯の刃先を結ぶ刃先線との交差角度を大きく、鋸身の先方部に位置する鋸歯の基方側縁である切れ刃と鋸歯の刃先を結ぶ刃先線との交差角度を小さく形成したことを特徴とするカーブソー。
- 凹弧状側縁に形成する鋸歯の切れ刃と鋸歯の刃先を結ぶ刃先線との交差角度が、大きな角度である基部に位置するものから小さな角度である先方部に位置するものに、順次連続的に変化することを特徴とする請求項1記載のカーブソー。
- 凹弧状側縁の基部から先方部に形成する鋸歯を複数の領域に区分し、区分した領域ごとに個々の鋸歯の切れ刃と鋸歯の刃先を結ぶ刃先線との交差角度を変化させることを特徴とする請求項1記載のカーブソー。
