Description

本考案は木工用、或は竹挽き用及び樹脂用鋸における鋸刃に関する。 The present invention relates to a saw blade for woodworking, or for bamboo sawing and resin sawing.

従来の鋸刃は、複数の列状刃先によって切断対象物の状態や切断方向、そして切削速度に合わせた刃先が形成され用いられてきた。
また特公平７−８５８８１号公報には、縦引き用の手引き鋸の鋸刃として、鋸の引き方向に対して面垂直な下刃を有する縦引き歯であり、その刃は、第１縦引き歯１と、第２縦引き歯２とに区別され、第１縦引き歯１は、左右に振り分ける２刃で形成され、第２縦引き歯２は、刃の先端部を鋭利な尖頭状の上目１２ｂに削成し、前記第１縦引き歯１の所定目数ごとに挿入して形成された鋸刃が提供されている（特許文献１）。
また特開２００２−３２１２０２号公報には、アサリ振りした先端に上目８を削成したアサリ歯２と、最先端５に略同一線状の刃付部４を形成した切り歯３とで形成され、前記アサリ歯２を配列する中に、歯の先端が該アサリ歯２より突出する前記切り歯３を混在配置して構成された鋸刃が提供されている（特許文献２）。A conventional saw blade has been used by forming a cutting edge in accordance with the state of the object to be cut, the cutting direction, and the cutting speed by a plurality of row-shaped cutting edges.
Japanese Patent Publication No. 7-85881 discloses a vertical pulling tooth having a lower blade perpendicular to the saw pulling direction as a saw blade for a vertical pulling hand saw. The first vertical pulling tooth 1 is formed with two blades that are distributed to the left and right, and the second vertical pulling tooth 2 has a sharp pointed tip at the tip of the blade. There is provided a saw blade that is formed by cutting into the upper eye 12b and inserting it for each predetermined number of the first longitudinal pulling teeth 1 (Patent Document 1).
Japanese Patent Application Laid-Open No. 2002-321202 is formed by a set tooth 2 having a top edge 8 cut at the tip of the set and a cutting tooth 3 having a cutting edge 4 that is substantially collinear at the most distal end 5. In addition, a saw blade is provided in which the cutting teeth 3 whose tips protrude from the set teeth 2 are mixedly arranged while the set teeth 2 are arranged (Patent Document 2).

また特許文献１に示す鋸刃の場合、前記第１縦引き歯１の配列が前記第２縦引き歯２の挿入配列数より多いため、切断機能が不十分となり、木材を縦引きする場合は切断が出来ても、切れ味が悪いため他の切断物を軽快に切断し難いことや、力を入れて切断しないといけない問題がある。
また特許文献２に示す鋸刃の場合、前記切り歯３が前記アサリ歯２よりも突出しているため、木材などを切断する時に歯の高低差によって鋸が上下に跳ねるようになり、鋸を挽く際、力を入れて切断なければならない不便さや、その切断において何度も引っ掛かかり切れ味が悪いなどの問題があった。Further, in the case of the saw blade shown in Patent Document 1, since the arrangement of the first vertical pulling teeth 1 is larger than the number of the arranged arrangements of the second vertical pulling teeth 2, the cutting function becomes insufficient, and the wood is pulled vertically. Even if it can be cut, there is a problem that it is difficult to cut other cuts lightly because of poor sharpness, and there is a problem that it is necessary to cut with force.
In the case of the saw blade shown in Patent Document 2, since the cutting teeth 3 protrude from the set teeth 2, when the wood or the like is cut, the saw jumps up and down due to the height difference of the teeth, and the saw is ground. At this time, there are problems such as inconvenience that must be cut with force and that the cutting is caught many times and the sharpness is poor.
