Abstract

PROBLEM TO BE SOLVED: To provide a high branch cutting saw which can cut a high branch by just grasping a handle and pulling a sliding gripper using a saw and a holding bar for clamping a branch which are mounted at the tip of a pipe in order to cut a high branch.SOLUTION: A saw tooth 1 mounted on the tip of a pipe 3 and a holding bar 2 mounted to clamp a branch are mounted on a stay 10 mounted on the tip of the pipe, a spring 13 is provided in a fulcrum 6 thereof so that the holding bar is always opened from the saw tooth by the restitution of the spring, the stay is connected to a sliding gripper 4 by a wire 11, and a holding part spring 9 is inserted into the gap between the stay and the sliding gripper so as to prevent the branch from being held more strongly than necessary. A pulling part stopper 7 is a stopper for stopping the sliding gripper, an opening part stopper 8 is a stopper for preventing the holding bar from opening too much, and a guide 12 is for suppressing waving of the wire.SELECTED DRAWING: Figure 1

Description

本発明は、高い場所の枝を切断するために、パイプの先端に取り付けた鋸と枝を挟む押え棒に依って、持ち手とスライド握り手を握り鋸を引くだけで高い場所の枝を切断出来る高枝切る鋸に関するものである。The present invention uses a saw attached to the end of a pipe and a presser bar that sandwiches the branch to cut the branch at a high place, and the branch at a high place can be cut only by grasping the handle and the slide gripping hand and pulling the saw. It relates to a saw that can cut high branches.

高枝切り鋸は、パイプの先端に鋸を取り付け、枝に治具を引っ掛けたり、鋸と鎌を先端に取り付け、枝を挟んで切ったり、鋸歯が向かい合わせになり、その中へ枝を入れて切断する鋸がある。A high branch cutting saw attaches a saw to the tip of a pipe, hooks a jig to the branch, attaches a saw and a sickle to the tip, cuts across the branch, saw blades face each other, put a branch into it There is a saw to cut.

特開２０１２−０３９９４２特開２０１１−０８７５０６特開２０００−２３６７４８特許文献１においては、枝を挟んで鋸で切る方法であるが、枝を挟まなければならず、高い場所に有る枝を挟むのは技術が必要であり、鎌の刃が枝との摩擦で切りにくいのではないか。
特許文献２においては、特許文献１同様に枝を挟む作業が必要で有り、鋸を引く場合に鋸で枝を押す力が必要である。バネの常時弾発付勢する力だけでは、枝を挟む力が弱い様に思う。
特許文献３においては、枝にフックを掛ける様にパイプ支えを使用し、枝を固定することは大変良い方法と思うが、治具を取り付けることで先端部分が重くなるのと、ロープで鋸歯を動かすのは大変疲れると思う。 JP 2012-039942 A JP 2011-087506 A JP 2000-236748 In Patent Document 1, it is a method of sandwiching and cutting with a branch, but it is necessary to sandwich the branch, and a technique is necessary to sandwich the branch at a high place, and the blade of the sickle is caused by friction with the branch. Isn't it difficult to cut?
In Patent Document 2, as in Patent Document 1, an operation for pinching a branch is necessary, and when a saw is drawn, a force for pushing the branch with a saw is required. I think that the force to pinch the branches is weak only by the force of the springs constantly firing and energizing.
In Patent Document 3, using a pipe support like a hook on a branch and fixing the branch is a very good method, but when the tip becomes heavy by attaching a jig, I think it ’s very tired to move.

特許文献の開示で見られるように、鋸歯を向かい合わせに取り付けた物や、枝を押えて切る方法や、枝を挟んで切る方法が開示されているが、枝を鋸で押し付けなければならない、これは作業上とても疲れる。鋸は切る物に対して押して引かなければ切れない、高い場所に有る枝に押す力を持続するのは大変な労力を必要とする。本発明は、枝を鋸歯で押しつける力は必要とせず、鋸を引くだけで高い場所の枝を切ることが出来る鋸を提供する。As seen in the disclosure of the patent document, a method in which saw blades are attached to each other, a method of pressing and cutting a branch, and a method of cutting by sandwiching a branch are disclosed, but the branch must be pressed with a saw, This is very tiring to work. A saw needs to be pushed and pulled against the material to be cut, and maintaining a pushing force on a branch in a high place requires great effort. The present invention provides a saw that does not require the force of pressing a branch with a saw tooth and can cut a branch at a high place by simply pulling the saw.

本発明は、パイプ（３）の先端に取り付けられた鋸歯（１）と、枝を挟む為に取り付けた押え棒（２）を、パイプ（３）の先端部のステー（１０）に付け、その支点（６）にはバネ（１３）を設け、常に鋸歯（１）より押え棒（２）がバネ（１３）の反発力で開く様にする。ステー（１０）と、スライド握り手（４）の、間はワイヤー（１１）で接続され、その間には押え部スプリング（９）を入れることで、必要以上に枝を押え込まない為のものである。引き部ストッパー（７）は、スライド握り手（４）を止めるためのストッパーである。開き部ストッパー（８）は、押え棒が開き過ぎるのを止めるためのストッパーで、ガイド（１２）は、ワイヤー（１１）が、波打つのを防ぐものである。The present invention attaches the saw blade (1) attached to the tip of the pipe (3) and the presser bar (2) attached to sandwich the branch to the stay (10) at the tip of the pipe (3). A spring (13) is provided at the fulcrum (6) so that the presser bar (2) is always opened by the repulsive force of the spring (13) from the saw tooth (1). The stay (10) and the slide grip (4) are connected by a wire (11), and a presser spring (9) is inserted between them to prevent the branch from being pushed more than necessary. is there. The pulling portion stopper (7) is a stopper for stopping the slide grip hand (4). The opening portion stopper (8) is a stopper for stopping the presser bar from opening too much, and the guide (12) prevents the wire (11) from wavy.

本発明は、パイプの先端に取り付けた鋸歯と、枝を挟む為の押え棒をパイプの先端部に付けたステーに取り付け、持ち手を持ちスライド握り手を引く事で、ワイヤーと接続された押え棒が枝を挟み、鋸を引く力が鋸を枝に押しつける力になるので引く力だけで切ることが出来る鋸である。The present invention provides a presser connected to a wire by attaching a saw tooth attached to the tip of a pipe and a presser bar for holding a branch to a stay attached to the tip of the pipe, holding the handle and pulling the slide gripping hand. This is a saw that can be cut only with the pulling force because the rod pinches the branch and the force of pulling the saw pushes the saw against the branch.
