Description

【０００１】
【産業上の利用分野】
本発明は、切断した枝を挟持する枝保持機構を備えた高枝鋏に関するものである。
【０００２】
【従来の技術】
高枝鋏は、周知の通り伸縮棒体の先部に、枢結した固定刃体と可動刃体で構成した鋏部を設け、基部に前記可動刃体と伝達杆を介して連結して鋏部を動作させる操作部を設けてなる。
【０００３】
また前記高枝鋏には、切断した枝をそのまま保持する枝挟み機構を備えた器具も知られている（特許文献１、２）。
【０００４】
特許文献１に開示されている高枝鋏は、可動刃体の側面に突出固定した基盤に、刃縁に隣接した枝挟み板の背面に設けた２本の支軸を出入自在に挿着し、基盤と枝挟み板との間に圧縮発条を改装し、固定刃体に付設した固定枝受け部とで切断枝を挟圧保持するようにしているものである。
【０００５】
また特許文献２に開示されている高枝鋏は、枝挟み部を、一端に案内部を有する板バネで形成し、前記板バネは、ほぼ鋏部の枢結軸上の位置で装着される一端から、一旦前方へ延設された後、刃縁先端付近で折り返されて再び後方へ延設され、他端が前記一端と重合状態にて案内部へ摺動可能に挿入されるごとく、ほぼ閉ループ状に湾曲形成してなり、固定枝受け部と前記枝挟み部で、切断枝を挟圧保持するようにしているものである。

【０００７】
【発明が解決しようとする課題】
前記した従来の高枝鋏の枝挟み機構は、可動枝挟み部の枝挟み面が平行に移動（特許文献１）するか、先端側が開口する方向へ移動（特許文献２）する構成である。
【０００８】
ところで細い枝の切断並びに枝保持についてはあまり問題は生じないが、太い枝を切断した場合には、枝挟み面が平行移動した場合には、切断枝と枝挟み面とが点接触であり、切断枝が他の枝に接触したり、風に煽られたりするなど、切断枝に不測の力が作用すると容易に枝の保持が解除されてしまう虞がある。また先端側が開口移動する枝挟みでは、切断枝を先端側で切断保持すると、剪断力及び保持力が弱いし、根元側ほど（枢結軸に近い方）剪断力並びに保持力が高まるが、根元側の枝挟み部は開口方向への移動が制限されるので、結果的に当該箇所での枝の切断可能太さに限界があり、太い枝は刃先側での切断保持となってしまう。
【０００９】
そこで本発明は、枝が太くとも切断刃の根元側で枝切断並びに枝保持が可能な高枝鋏を提案したものである。
【００１０】
【課題を解決する手段】
本発明に係る高枝鋏は、伸縮棒体の先部に、枢結した固定刃体と可動刃体で構成した鋏部を設け、基部に前記可動刃体を動作させる操作部を設けた高枝鋏において、固定刃体の側面に固定刃体の受け湾曲形状の刃縁に添って固定枝受け部を設け、可動刃体側に前記固定枝受け部に対面して枝挟み面を備え、刃先部分で枢結して回動自在に可動刃体に装着した可動枝挟み部を設けると共に、枝挟み面が固定枝受け部から遠ざかる回動に対して抵抗付勢する発条を付設したことを特徴とするものである。
【００１１】
従って枝を開口した刃体の間のできるだけ根元に差し入れ、操作部の動作で枝の切断を行うと共に、可動枝挟み部が回動することで、枝挟み部が切断の邪魔になることが無く、切断後は、固定枝受け部とで挟圧保持するものである。
【００１２】
【実施の形態】
次に本発明の実施の形態について説明する。全体の基本的構成は、従前の高枝鋏と同様で、伸縮棒体１と、鋏部２と操作部３を備え、鋏部２に枝保持機構４を付設したものである。
【００１３】
伸縮棒体１は内筒体１１と外筒体１２からなる二重筒体で、抜き差し自在にして伸縮可能とし、特に内部に伝達杆１３を内装し、伝達杆１３の伸縮並びに内外筒体１１，１２の伸縮固定操作を行う調整部１４を備えてなる。また内筒体１１の先端には、後述する鋏部２の固定刃体２１を連結し先端側面に鋸装着部１５を設けてなる。
【００１４】
鋏部２は、固定刃体２１と可動刃体２２とを備え、固定刃体２１は受け湾曲形状の刃を備え、その基部を内筒体１１の先端に連結固定しており、可動刃体２２は、半月状の刃で、固定刃体２１に枢結（枢結軸２３）すると共に、基端を伝達杆１３と連結してなる。
【００１５】
操作部３は、固定把手３１と操作把手３２とを備え、固定把手３１は外筒体１２の下端に連結固定し、操作把手３２を固定把手３１に枢結して回動自在とし、操作把手３２の所定位置に伝達杆１３を連結し、操作把手３２の開閉操作で鋏部２の開閉操作を行うようにしてなる。また操作把手３２を握持して鋏部２が閉じた状態を維持させるロック部３３を設けてなる。
【００１６】
本発明の特徴である枝保持機構４は、固定枝受け部４１と可動枝挟み部４２とを備えたもので、固定枝受け部４１は、固定刃体２１の側面に固定刃体２１の受け湾曲形状の刃縁に添って設けたもので、湾曲受け面は、刃縁に直交する細かい凹凸状に形成してなる。
【００１７】
可動枝挟み部４２は、鋏部２を全閉した状態で固定枝受け部４１の湾曲受け面と対応する枝挟み面４３を備え、枝挟み面４３と反対側の峰面が可動刃体２２の峰部とほぼ一致させた形状である。即ち可動刃体２２の刃縁部分が可動枝挟み部４２の枝挟み面４３より突出してなるものである。
【００１８】
前記の可動枝挟み部４２は、峰面に板バネ体４４を添わせ、可動刃体２２の先部において枢結（枢結軸４５）し、可動刃体２２の外側面に添わせると共に、板バネ体４４の先方上面に庇状に突出させた支点部体４６を、可動刃体２２に固定してなる。
【００１９】
また可動枝挟み部４２の根元側（枢結軸２３に近い方）に、枢結軸４５と平行にガイド軸４７をガイド長溝４８に挿着して、可動刃体２２側に突出させ、可動刃体２２に、前記ガイド軸４７が収まる枢結軸４５を中心とする円弧状のガイド長溝４９を設けてなる。
【００２０】
而してロック部３３を解除して、切断対象の枝Ａを開口した刃体２１，２２の間のできるだけ根元側に差し入れ、操作部（固定把手３１と操作把手３２）の握持操作で鋏部２の開閉動作を行って、枝Ａの切断をなす。前記の切断途中で枝Ａは、固定枝受け部４１と、可動枝挟み部４２とで挟圧され、切断終了時には、可動枝挟み部４２が回動し、支点部体４６で一端が抑えられている板バネ体４４が撓曲することで、挟圧力が生じ、切断後の枝Ａをしっかりと保持するものである。尚可動枝挟み部４２の可動範囲はガイド長溝４８，４９の長さの合算範囲である。
【００２１】
【発明の効果】
以上のように本発明は、高枝鋏の鋏部に枝挟み機構を付設してなり、特に当該機構を、可動刃体側に固定枝受け部に対面して枝挟み面を備え、刃先部分で枢結して回動自在に可動刃体に装着した可動枝挟み部を設けると共に、枝挟み面が固定枝受け部から遠ざかる回動に対して抵抗付勢する発条を付設して構成したもので、枝が太くとも切断刃の根元側で枝切断並びに枝保持を可能として、効果的な切断枝保持を実現した高枝鋏を提供できたものである。

[Industrial application fields]
The present invention relates to a high branch ridge having a branch holding mechanism for holding a cut branch.
[0002]
[Prior art]
As is well known, the Takaeda ridge is provided with a collar portion composed of a fixed fixed blade body and a movable blade body at the tip portion of the telescopic rod body, and is connected to the base portion via the movable blade body and a transmission rod. The operation part which operates is provided.
[0003]
In addition, a device having a branch pinching mechanism that holds a cut branch as it is is also known as the high branch ridge (Patent Documents 1 and 2).
[0004]
The Takaashi ridge disclosed in Patent Document 1 is inserted into the base that protrudes and is fixed to the side surface of the movable blade body so that the two support shafts provided on the back surface of the branch sandwich plate adjacent to the blade edge can be freely inserted and removed. The compression ridge is refurbished between the base and the branch pinching plate, and the cutting branch is pinched and held by the fixed branch receiving portion attached to the fixed blade body .
[0005]
Moreover, the high branch ridge disclosed in Patent Document 2 has a branch pinching portion formed by a leaf spring having a guide portion at one end, and the leaf spring is mounted at a position substantially on the pivot shaft of the heel portion. After being extended forward, it is folded back in the vicinity of the edge of the blade edge and extended backward again, so that the other end is slidably inserted into the guide portion in the overlapped state with the one end. The cutting branch is clamped and held by the fixed branch receiving portion and the branch pinching portion.

[Patent Document 2]
Japanese Patent Laid-Open No. 9-9782.
[0007]
[Problems to be solved by the invention]
The above-described conventional pinch mechanism of a high branch hook is configured such that the branch pinch surface of the movable branch pinch part moves in parallel (Patent Document 1) or moves in the direction in which the tip side opens (Patent Document 2).
[0008]
By the way, there is not much problem with cutting a thin branch and holding a branch, but when a thick branch is cut, when the branch pinch plane moves in parallel, the cut branch and the pinch pinch surface are in point contact, If an unforeseen force is applied to the cut branch, such as when the cut branch comes into contact with another branch or is blown by the wind, the holding of the branch may be easily released. Moreover, in the branch pinching where the distal end side moves open, if the cutting branch is cut and held at the distal end side, the shearing force and holding force are weaker, and the shearing force and holding force increase toward the root side (the one closer to the pivot axis). Since the movement in the opening direction of the side pinch portion is restricted, there is a limit to the thickness at which the branch can be cut, and a thick branch is cut and held on the blade edge side.
[0009]
Therefore, the present invention proposes a high branch ridge that can cut and hold branches on the base side of the cutting blade even if the branches are thick.
[0010]
[Means for solving the problems]
The high-edged scissors according to the present invention are provided with a hooked part composed of a fixed fixed blade body and a movable bladed body at the tip of the telescopic rod body, and an operating part for operating the movable bladed body at the base part. The fixed blade body is provided with a fixed branch receiving portion on the side of the fixed blade body along the curved edge of the fixed blade body, the movable blade body is provided with a branch pinching surface facing the fixed branch receiving portion, A movable branch pinching portion pivotally connected to the movable blade body is provided, and a ridge that resists the rotation of the branch pin surface away from the fixed branch receiving portion is attached.
