[Prior art]

従来の枝打ち工具としてオノ・ナタ・ノコ等があるが木に昇って作業をする必要があり大変危険で重労働であつた。又エンジン付き枝打ち機は条件の整った一部の木にしか間に合いませんし機械自体の重量が重いため運搬取り付けが大変であつた。又伸縮自在棹による枝打ち工具もあるが太い枝や高い木の枝を打つのに充分（重量・能率等）でなかった。 Conventional pruning tools include Ono, Nata, and Saw, but it is very dangerous and hard work because it is necessary to climb to a tree and work. Moreover, the pruning machine with an engine can be used only for a part of trees that are in good condition, and the heavy weight of the machine itself makes it difficult to install and transport. There are also pruning tools that use flexible rods, but they were not sufficient (weight, efficiency, etc.) to hit thick branches or tall tree branches.

B) It is safe and easy to work because you do not have to climb trees. B) This machine is lightweight and can be manufactured. C) You can hit thick branches and tall tree branches. 2 Work can be performed regardless of weather conditions such as wind and rain. B) Because there is no need to climb a tree. 3 Work efficiency is good and costs are low. B) A tree climbing tool (such as a ladder) is not required, and pruning can be done with this single machine. B) Since it is a simple machine, it can be used for a long period of time by simply sharpening the blade or replacing the blade when it becomes difficult to cut. C) This machine can be cheap, so the cost is low.

[Means for Solving the Problems]

のこ刃で木の枝を切る場合には押し付ける力と引く力を同時に作用させなければ木の枝は切れない。押し付ける力は枝から離れるほど力が弱くなり、よつて木の枝のように高いところの枝をのこ刃にて切る場合には距離に関係なく、のこ刃に適度の押し付ける力を作用させる必要がある。よつてこの考案は枝に対し常に適度の押し付ける力を作用させ引く力だけで木の枝を切るものである。のこ刃（１）を固定ワク（５）に回転軸（２）にて取り付け、のこ刃（１）の先端にワイヤー（３）等にて取り付けワイヤー（３）等を通し方向を変える装置（４）固定ワク（１）に取り付けバネ等の弾性体（６）をワイヤー（３）等に接続しネジ（７）等にて固定ワク（５）に取り付ける。又この本機と伸縮竿（８）を脱着装置（９）により取り付ける手動軽量枝打ち機である。 When cutting a tree branch with a saw blade, the pressing force and the pulling force must be applied simultaneously to cut the tree branch. The force of pressing becomes weaker as it moves away from the branch, and when cutting a branch at a high place like a tree branch with a saw blade, an appropriate pressing force is applied to the saw blade regardless of the distance. There is a need. Therefore, this invention always cuts a tree branch by applying an appropriate pressing force to the branch and pulling it. Attach the saw blade (1) to the fixed frame (5) with the rotating shaft (2), and attach the wire (3) to the tip of the saw blade (1) with the wire (3) etc. Fixing the device (4) Attach the elastic body (6) such as a spring to the wire (3) and attach it to the wire (3) with screws (7) and the like. It is also a manual light-weight pruning machine that attaches this machine and a telescopic rod (8) with a detaching device (9).

[Action]

伸縮自在竿（８）を両手で握り本機の、固定ワク（５）を木の枝の根元に挟み込み伸縮自在竿（８）を引くと、のこ刃（１）と固定ワク（５）に力がかかる。のこ刃（１）にかかる力は回転軸（２）と、のこ刃の先端の二箇所で、のこ刃の先端にかかる力はバネ等の弾性体（６）の作用により、のこ刃（１）の先端が固定ワク（５）に接してひらく。又伸縮竿（８）を押すと、のこ刃（１）及び固定ワク（５）にかかる力は弱くなり元に戻ろうとする。これをくりかえす。 Grasp the telescopic rod (8) with both hands, sandwich the fixed stick (5) of this machine at the base of the tree branch, and pull the telescopic rod (8) to saw the saw blade (1) and the fixed stick (5). Takes power. The force applied to the saw blade (1) is at two points, the rotating shaft (2) and the tip of the saw blade, and the force applied to the tip of the saw blade is due to the action of an elastic body (6) such as a spring. Open the tip of the blade (1) in contact with the fixed arm (5). Further, when the telescopic rod (8) is pushed, the force applied to the saw blade (1) and the fixed tack (5) becomes weak and tries to return to the original state. Repeat this.

【Example】

私は、市販の枝打ち工具、機械（枝打ちロボット）を購入して、自分の山林の枝打ち作業を行ってまいりましたが、木に上って枝打ち作業をするのは大変危険で重労働である。又機械は条件の整った一部の木にしか間にあいませんし、運搬、取り付けが大変である。又、木が濡れてる場合には作業ができない点がある。そのため自然条件に左右されずに誰でも安全で簡単に作業ができる方法はないか考えてきた訳です。本考案は、図１・図２・図３のとおり試作機（枝径６５ｍｍ高さ６ｍ迄・重量本機０，３５ｋｇ・５ｍのアルミ伸縮棹１，３５ｋｇ合計１，７ｋｇ）を作り自分の山林にて実演してまいりました。以下、図に基づいて説明する。伸縮棹（８）本機を脱着装置（９）により取り付け、伸縮棹（８）を両手で握り木の枝の高さまで伸縮棹（８）を伸ばして固定し、木の枝の根元へ本機を上から乗せるようにし、伸縮棹（８）を引くと、のこ刃（１）と固定ワク（５）に力がかる。のこ刃（１）にかかる力は回転軸（２）とのこ刃（１）の先端の二箇所で、のこ刃（１）の先端にかかる力はバネ等の弾性体（６）の働きによりのこ刃（１）に適度の押し付ける力をかけ、のこ刃の先端が固定ワク（５）に接してひらく。伸縮棹（８）を押すと、のこ刃（１）及び固定ワク（５）にかかる力は弱くなり元に戻ろうとする。これをくりかえす。（伸縮棹を上げ下げするだけ） I purchased commercially available pruning tools and machines (pruning robots) to do the pruning work in my forest, but climbing trees to do pruning work is very dangerous and hard work. In addition, the machine is only available for some trees that are in good condition, which makes transportation and installation difficult. Moreover, there is a point that work cannot be performed when the tree is wet. Therefore, we have been wondering if there is a safe and easy way for anyone to work regardless of the natural conditions. As shown in Fig. 1, Fig. 2 and Fig. 3, this invention made a prototype machine (branch diameter 65mm, height 6m, weight machine 0,35kg, 5m aluminum expansion rod 1,35kg, total 1,7kg) and made my own forest. I have demonstrated it at. The following is a description based on the figure. Telescopic rod (8) Attach this machine with the detaching device (9), hold the telescopic rod (8) with both hands and extend and fix the telescopic rod (8) to the height of the branch of the tree, and then fix it to the root of the tree branch. With the machine on top and pulling on the telescopic rod (8), force is applied to the saw blade (1) and the fixed tack (5). The force applied to the saw blade (1) is at two points, the rotating shaft (2) and the tip of the saw blade (1), and the force applied to the tip of the saw blade (1) is due to the action of an elastic body (6) such as a spring. Apply an appropriate pressing force to the saw blade (1) so that the tip of the saw blade comes into contact with the fixed arm (5) and opens. When the telescopic rod (8) is pushed, the force exerted on the saw blade (1) and the fixed sack (5) becomes weak and tries to return to the original state. Repeat this. (Just raise and lower the expansion rod)

[Effect of device]

本考案は上記した構造をなすものであるから、木の下より本機の伸縮竿を上げ下げするだけで、木の高さや、木の種類に関係なく能率良く安全に枝打ちできる。又、本機は小型軽量であり、素人でも枝打ち可能で、天候に左右されずに作業ができるため、底コストで山林保全管理に役立つ効果がある。 Since the present invention has the above-mentioned structure, it is possible to prun efficiently and safely regardless of the height of the tree and the type of tree by simply raising and lowering the telescopic rod of this machine from under the tree. In addition, this machine is small and lightweight, and even practitioners can prun it and can work without being affected by the weather.
