特開２００３−８８２４５号公報 The hedge trimmer is used for cutting branches and leaves of a planted tree or the like, and for example, the following technique has been disclosed.
JP 2003-88245 A

図９に示すように、従来のヘッジトリマ１０１は、エンジン等の動力駆動手段を備える本体部１０２と、この本体部１０２に片持梁状態で端部を固定される固定板１０３と、動力駆動手段にその基端部を連結し、動力駆動手段より伝達される動力によって相対的な摺動運動を行なう上下２枚の可動刃１０４，１０５を有し、把持手段として本体部１０２の後方に突出する後方ハンドル１０６及び固定板１０３に装着される前方ハンドル１０７を備えており、可動刃１０４，１０５の前方側部には剪定面を案内するカバー１０８が取付けられていた。 As shown in FIG. 9, a conventional hedge trimmer 101 includes a main body portion 102 having power driving means such as an engine, a fixed plate 103 whose end is fixed to the main body portion 102 in a cantilever state, and power driving means. And has two upper and lower movable blades 104 and 105 that perform relative sliding movements by the power transmitted from the power drive means, and project rearward of the main body 102 as grip means. A front handle 107 attached to the rear handle 106 and the fixed plate 103 is provided, and a cover 108 for guiding the pruning surface is attached to the front side portions of the movable blades 104 and 105.

このような従来のヘッジトリマにおける可動刃の詳細を図１０に示す。図１０は、従来の可動刃及び固定板の組立状況を示す分解斜視図である。長手方向に摺動自在に往復動する一対の可動刃１０４，１０５は、図示しない本体部より突出する上下二枚の固定板１０３，１１３の間に配置されており、各可動刃１０４，１０５に形成する複数のガイド長孔１０４ａ，１０５ａに夫々ボルト１０９ａを貫通していた。 Details of the movable blade in such a conventional hedge trimmer are shown in FIG. FIG. 10 is an exploded perspective view showing an assembly state of a conventional movable blade and fixed plate. A pair of movable blades 104 and 105 slidably reciprocating in the longitudinal direction are disposed between two upper and lower fixed plates 103 and 113 protruding from a main body (not shown). The bolts 109a are respectively passed through the plurality of guide long holes 104a and 105a to be formed.

このボルト１０９ａは、固定板１０３，１１３に穿設するボルト孔１０３ａ，１１３ａを貫通し、両固定板１０３，１１３の間隔を一定に保持するためのスペーサ１１０を介在させてナット１０９ｂを用い締結されていた。 The bolt 109a passes through bolt holes 103a and 113a formed in the fixing plates 103 and 113, and is fastened using a nut 109b with a spacer 110 interposed between the fixing plates 103 and 113 so as to maintain a constant distance. It was.

一対の可動刃１０４，１０５は、夫々の外側縁に切刃１０４ｂ，１０５ｂを所定間隔で突出しており、これら切刃１０４ｂ，１０５ｂは可動刃１０４，１０５の長手方向の全長にわたり、連続して一様なパターンを繰り返していた。 The pair of movable blades 104 and 105 project the cutting blades 104b and 105b at their respective outer edges at a predetermined interval, and these cutting blades 104b and 105b are continuously arranged over the entire length in the longitudinal direction of the movable blades 104 and 105. The pattern was repeated.

可動刃１０４，１０５は、固定板１０３，１１３の間にあって、スペーサ１１０により遊動可能な状態を維持しつつ、ガイド長孔１０４ａ，１０５ａに沿って長手方向に相対的な摺動運動を行ない、切刃１０４ｂ，１０５ｂを相互に重合・離隔することによって挟み込む垣根等の樹木の枝葉を切断していた。 The movable blades 104 and 105 are located between the fixed plates 103 and 113 and perform a relative sliding movement in the longitudinal direction along the guide long holes 104a and 105a while maintaining a state in which they can be freely moved by the spacer 110. The blades 104b and 105b are superposed and separated from each other to cut the branches and leaves of a tree such as a fence.

このように固定板１０３，１１３及びボルトナット１０９ａ，１０９ｂは、可動刃１０４，１０５を遊動可能な状態で支持すると共に長手方向への往復動をガイドするための構成要素であった。 As described above, the fixed plates 103 and 113 and the bolt nuts 109a and 109b are components for supporting the movable blades 104 and 105 in a freely movable state and guiding reciprocation in the longitudinal direction.

図９および図１０に示すヘッジトリマ１０１はハンディタイプのもので、図示しない作業者が後方ハンドル１０６及び前方ハンドル１０７を把持しながら、本体部１０２の動力によって一対の可動刃１０４，１０５を長手方向に摺動自在に往復動させ、これら可動刃１０４，１０５をその切刃１０４ｂ，１０５ｂ方向に前進させることによって樹木等の剪定作業を行っていた。 The hedge trimmer 101 shown in FIGS. 9 and 10 is of a handy type, and an operator (not shown) holds the rear handle 106 and the front handle 107 while moving the pair of movable blades 104 and 105 in the longitudinal direction by the power of the main body 102. Pruning work such as trees is performed by reciprocating slidably and moving the movable blades 104 and 105 forward in the direction of the cutting blades 104b and 105b.

しかし、塀や建物などの構築物に沿って樹木が植栽されている場合には、最先端の切刃１０４ｂ，１０５ｂより構築物際に位置する枝は刈り取ることができなかった。これは、可動刃１０４，１０５が往復動によって構築物に衝突することを防止するためある程度先端部を構築物から離隔する必要があったこと、又先端部に衝突防止用のカバーがあって構築物に当接しながら剪定することは可能であっても最先端の切刃１０４ｂ，１０５ｂより構築物際に位置する枝を挟み込むことはできないため、このような枝葉については別途手作業にて剪定しなければならなかった。 However, when a tree is planted along a structure such as a fence or a building, a branch located at the time of the structure cannot be cut off from the cutting edges 104b and 105b. This is because it is necessary to separate the tip part from the structure to some extent in order to prevent the movable blades 104 and 105 from colliding with the structure due to reciprocation, and there is a collision prevention cover at the tip part so Although it is possible to prun while touching, the branches located at the time of construction cannot be sandwiched by the cutting edges 104b and 105b, so such branches and leaves must be manually pruned separately. It was.

この発明は、従来のヘッジトリマが有する上記の問題点を解消すべくなされたものであり、塀や建物などの構築物に沿って樹木が植栽されている場合にも構築物際の枝葉を刈り取ることが可能なヘッジトリマを提供することを目的としている。 This invention was made to eliminate the above-mentioned problems of conventional hedge trimmers, and even when trees are planted along structures such as bushes and buildings, branches and leaves at the time of construction can be cut off. It aims to provide a possible hedge trimmer.

上記課題を解決するため、この発明のヘッジトリマは、動力駆動手段を備える本体部より突出する固定板と、この固定板に支持され前記動力駆動手段より伝達される動力によって相対的な摺動運動を行ない夫々の外側縁に形成した切刃で枝などを剪定する上下２枚の可動刃を有するヘッジトリマにおいて、前記可動刃の先端部上側又は先端部下側に切刃先端より前方に突出する枝葉誘導板を設けることを特徴とするものである。 In order to solve the above-described problem, the hedge trimmer of the present invention performs a relative sliding motion by a fixed plate protruding from a main body portion having power driving means and power transmitted from the power driving means supported by the fixed plate. In a hedge trimmer having two upper and lower movable blades for pruning branches and the like with a cutting blade formed on each outer edge, the branch leaf guide plate that protrudes forward from the cutting blade tip to the upper side or the lower side of the tip of the movable blade Is provided.

枝葉誘導板は、可動刃が遊動可能なように離隔して設置し、枝葉を切刃間に誘導するための斜め切欠部を形成する。枝葉誘導板は、固定板の先端に一体的に形成するものでもよいし、独立した板体を取り付けるものでもよい。独立した板体の場合には、固定板若しくは固定板に取付けられるカバーなどから連結部材を用いて可動刃と接触しない位置に付設する。 The branch and leaf guide plate is installed so as to be movable so that the movable blade can move freely, and forms an oblique notch for guiding the branch and leaf between the cutting blades. The branch and leaf guide plate may be formed integrally with the tip of the fixed plate, or may be an independent plate. In the case of an independent plate, it is attached at a position where it does not contact the movable blade using a connecting member from a fixed plate or a cover attached to the fixed plate.

請求項２記載のヘッジトリマにおける可動刃は、相対的な摺動運動時にあっても前記枝葉誘導板との重合部を有する先端切刃を備えることを特徴とするものである。先端切刃は、一方の可動刃に形成するものであって少なくとも隣接する切刃方向の側面に刃部を設ける。 The movable blade in the hedge trimmer according to claim 2 is provided with a tip cutting edge having an overlapping portion with the branch and leaf guide plate even during relative sliding movement. The tip cutting edge is formed on one movable blade, and is provided with a blade portion on at least the side surface in the direction of the adjacent cutting edge.

この先端切刃が前方側に、他方の可動刃が手元側に夫々摺動した時、先端切刃の刃部と他方の可動刃における最先端の切刃間に空隙が生じ、誘導された枝葉を収容する。その後、先端切刃が手元側に、他方の可動刃が前方側に移動すると挟み込んだ枝葉を切断する。 When this tip cutting edge slides forward and the other movable blade slides to the proximal side, a gap is created between the cutting edge of the tip cutting edge and the cutting edge of the other movable blade, and the induced branches and leaves To accommodate. Thereafter, when the tip cutting edge moves to the proximal side and the other movable blade moves to the front side, the sandwiched branches and leaves are cut.

この時、枝葉誘導板の斜め切欠部と先端切刃の前面は、夫々次に切断すべき枝葉に当接する。先端切刃及び他方の可動刃が、夫々限界値まで移動した場合であっても、先端切刃は枝葉誘導板との間に空隙を発生させない幅を有する。 At this time, the oblique notch portion of the branch and leaf guide plate and the front surface of the tip cutting blade are in contact with the branches and leaves to be cut next. Even when the tip cutting edge and the other movable blade move to their respective limit values, the tip cutting edge has a width that does not generate a gap between the branch leaf guide plate.

この発明のヘッジトリマは、可動刃の先端部上側又は先端部下側に切刃先端より前方に突出する枝葉誘導板を設けるので、塀や建物などの構築物に沿って樹木が植栽されている場合にも構築物際の枝葉を切刃間に誘導することができ、これを刈り取ることができる。 The hedge trimmer according to the present invention is provided with a branch and leaf guide plate protruding forward from the tip of the cutting blade on the upper end or lower end of the movable blade, so that when a tree is planted along a structure such as a fence or a building Also, the branches and leaves at the time of construction can be guided between the cutting blades, and this can be cut off.

請求項２記載のヘッジトリマは、相対的な摺動運動時にあっても枝葉誘導板との重合部を有する先端切刃を備えるので、先端切刃と枝葉誘導板との間に枝葉を挟み込むことがなくなり、切断不能により作動停止状態が発生するのを防止することができる。 Since the hedge trimmer according to claim 2 includes the tip cutting edge having the overlapping portion with the branch and leaf guide plate even during relative sliding motion, the branch and leaf can be sandwiched between the tip cutting blade and the branch and leaf guide plate. It is possible to prevent the operation stop state from occurring due to the inability to cut.

次にこの発明の実施の形態を添付図面に基づき詳細に説明する。図１はこの発明のヘッジトリマにおける可動刃及び固定板の組立状況を示す分解斜視図である。長手方向に摺動自在に往復動する一対の可動刃４，５は、図示しない本体部より突出する上下二枚の固定板３，１３の間に配置されており、各可動刃４，５に形成する複数のガイド長孔４ａ，５ａに夫々ボルト９ａを貫通する。 Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is an exploded perspective view showing an assembly state of a movable blade and a fixed plate in the hedge trimmer of the present invention. A pair of movable blades 4 and 5 slidably reciprocating in the longitudinal direction are disposed between two upper and lower fixed plates 3 and 13 protruding from a main body (not shown). The bolts 9a are respectively inserted through the plurality of guide long holes 4a and 5a to be formed.

このボルト９ａは、固定板３，１３に穿設するボルト孔３ａ，１３ａを貫通し、両固定板３，１３の間隔を一定に保持するためのスペーサ１０を介在させてナット９ｂを用い締結されている。上側の固定板３の下面には剪定面を案内するためのカバー８が挟み込まれる。 The bolt 9a passes through the bolt holes 3a and 13a formed in the fixing plates 3 and 13, and is fastened by using a nut 9b with a spacer 10 interposed between the fixing plates 3 and 13 so as to maintain a constant distance. ing. A cover 8 for guiding the pruning surface is sandwiched between the lower surface of the upper fixing plate 3.

一対の可動刃４，５は、夫々の外側縁に切刃４ｂ，５ｂが突出し、摺動する際に夫々の刃先が接触するような向きで形成されている。一方の可動刃５の先端部には幅広の先端切刃５ｃを設ける。先端切刃５ｃは一般切刃５ｂより前方に突出する切っ先部５ｄを設け、隣接する一般切刃５ｂ方向の側面に切断刃部５ｅを設ける。 The pair of movable blades 4 and 5 are formed in such an orientation that the cutting blades 4b and 5b protrude from the outer edges of the pair of movable blades 4 and 5 and the respective blade edges come into contact with each other when sliding. A wide end cutting edge 5 c is provided at the tip end of one movable blade 5. The tip cutting edge 5c is provided with a cutting edge part 5d protruding forward from the general cutting edge 5b, and a cutting edge part 5e is provided on the side surface in the direction of the adjacent general cutting edge 5b.

この可動刃５の下側に位置する下側固定板１３の先端部には一般切刃４ｂ，５ｂ及び先端切刃５ｃよりも前方に突出する枝葉誘導板１３ｂを形成する。枝葉誘導板１３ｂも切っ先部５ｄと同様な斜め切欠部１３ｃを形成する。 At the distal end portion of the lower fixed plate 13 positioned below the movable blade 5, the general cutting blades 4b and 5b and the branch and leaf guide plate 13b projecting forward from the distal cutting blade 5c are formed. The branch and leaf guide plate 13b also forms an oblique cutout 13c similar to the cut end 5d.

次に作動時における可動刃及び枝葉誘導板の位置関係を図２乃至図５に基づき説明する。図２は上面固定板を省略した可動刃の先端部拡大平面図、図３は下面固定板及び可動刃の先端部拡大底面図、図４及び図５は可動刃の摺動状態を示す先端部拡大底面図である。 Next, the positional relationship between the movable blade and the branch / leaf guide plate during operation will be described with reference to FIGS. 2 is an enlarged plan view of the tip of the movable blade with the upper surface fixed plate omitted, FIG. 3 is an enlarged bottom view of the tip of the lower surface fixed plate and the movable blade, and FIGS. 4 and 5 are tip portions showing the sliding state of the movable blade. It is an enlarged bottom view.

図２及び図３は上側可動刃４が手元側(図２において左方)、下側可動刃５が前方側（図２において右方）の限界値まで移動した状態を示す。この時上側可動刃４の切刃４ｂと下側可動刃５の切刃５ｂとの間には空隙Δ₀が形成されている。又、先端切刃５ｃの切断刃部５ｅと切刃４ｂとの間にも空隙Δが生じている。 2 and 3 show a state where the upper movable blade 4 has moved to the limit value on the hand side (left side in FIG. 2) and the lower movable blade 5 has moved to the limit value on the front side (right side in FIG. 2). At this time, a gap Δ ₀ is formed between the cutting edge 4 b of the upper movable blade 4 and the cutting edge 5 b of the lower movable blade 5. Further, a gap Δ is also generated between the cutting blade portion 5e of the tip cutting blade 5c and the cutting blade 4b.

下側可動刃５は前方に最大移動した場合であっても枝葉誘導板１３ｂの端部を越えないようにする。これにより枝葉誘導板１３ｂを構造物に当接しながら剪定しても可動刃４，５が構造物に衝突する恐れがなくなる。 Even when the lower movable blade 5 is moved forward to the maximum, it does not exceed the end of the branch guide plate 13b. Accordingly, there is no possibility that the movable blades 4 and 5 collide with the structure even when the branch guide plate 13b is pruned while being in contact with the structure.

上側可動刃４及び下側可動刃５が反対方向に移動し始めると、図４に示すように上側可動刃４の切刃４ｂと先端切刃５ｃの切断刃部５ｅの空隙Δは縮小し、この間に収容されていた枝葉は切断される。 When the upper movable blade 4 and the lower movable blade 5 begin to move in opposite directions, the gap Δ between the cutting blade 4b of the upper movable blade 4 and the cutting blade portion 5e of the tip cutting blade 5c is reduced as shown in FIG. The branches and leaves accommodated during this time are cut.

更に限界値まで移動すると図５に示すように、先端切刃５ｃの切断刃部５ｅは次の切刃４ｂの近傍まで摺動することになるが、この時であっても先端切刃５ｃの前方端部は枝葉誘導板１３ｂとの重合部を保持している。 When it further moves to the limit value, as shown in FIG. 5, the cutting blade portion 5e of the leading edge cutting blade 5c slides to the vicinity of the next cutting edge 4b. The front end portion holds the overlapping portion with the branch guide plate 13b.

次にヘッジトリマの使用状況を図６に基づき説明する。図６は構築物際の植栽を剪定する際の説明図である。塀や建物などの構築物６に沿って樹木が植栽されている場合には、枝葉誘導板１３ｂを構築物６にあてがい、これをガイドとして白抜き矢印の方向にヘッジトリマを移動させる。 Next, the usage status of the hedge trimmer will be described with reference to FIG. Drawing 6 is an explanatory view at the time of pruning planting in the case of a construction. When a tree is planted along the structure 6 such as a fence or a building, the branch guide plate 13b is applied to the structure 6, and the hedge trimmer is moved in the direction of the white arrow using this as a guide.

この時構築物際の樹木の枝葉７は枝葉誘導板１３ｂの斜め切欠部１３ｃに当接し、その斜面に沿って手元側に移動させられる。下側可動刃５が前方側限界まで移動した時、先端切刃５ｃの切断刃部５ｅと切刃４ｂとの間には空隙が生じているため、この空隙に誘導された枝葉７が収容される（図６（ａ））。 At this time, the branches and leaves 7 of the tree at the time of construction are brought into contact with the oblique notch 13c of the branch and leaf guide plate 13b and are moved to the hand side along the slope. When the lower movable blade 5 moves to the front limit, a gap is generated between the cutting blade portion 5e of the tip cutting blade 5c and the cutting blade 4b, so that the branches and leaves 7 guided in this gap are accommodated. (FIG. 6A).

その後、先端切刃５ｃが手元側に、他方の可動刃４が前方側に移動すると挟み込んだ枝葉７は切断される（図６（ｂ））。更に先端切刃５ｃの切断刃部５ｅが手元側の限界値まで移動した時、先端切刃５ｃの前方端部は枝葉誘導板１３ｂと未だ重なっているため、枝葉７は枝葉誘導板１３ｂの斜め切欠部１３ｃと先端切刃５ｃの切っ先部５ｄで支持されている（図６（ｃ）。 Thereafter, when the tip cutting edge 5c is moved to the proximal side and the other movable blade 4 is moved to the front side, the sandwiched leaves 7 are cut (FIG. 6B). Further, when the cutting blade portion 5e of the tip cutting edge 5c moves to the limit value on the hand side, the front end portion of the tip cutting edge 5c still overlaps the branch guide plate 13b, so that the branches and leaves 7 are oblique to the branch guide plate 13b. It is supported by the notch part 13c and the cutting edge part 5d of the tip cutting edge 5c (FIG. 6C).

枝葉誘導板１３ｂは、可動刃４，５から離隔して設置されているため、元々切断機能がなく、先端切刃５ｃと枝葉誘導板１３ｂとの間に枝葉が挟まってしまうとヘッジトリマが作動停止状態となってしまう。このように先端切刃５ｃと枝葉誘導板１３ｂが重合部を常に保持している構成であると、切断不能による作動停止状態が発生するのを防止することができる。 Since the branch and leaf guide plate 13b is installed separately from the movable blades 4 and 5, there is originally no cutting function, and the hedge trimmer is deactivated when a branch or leaf is caught between the tip cutting blade 5c and the branch and leaf guide plate 13b. It becomes a state. Thus, when the tip cutting edge 5c and the branch and leaf guide plate 13b are configured to always hold the overlapping portion, it is possible to prevent the operation stop state due to the inability to cut.

以上説明したヘッジトリマは可動刃の先端部下側において、下側固定板の先端に一体的に枝葉誘導板を形成する構成であるが、枝葉誘導板は可動刃の先端部上側、例えば上側固定板に一体的に設けるものでもよい。 The hedge trimmer described above has a structure in which the branch and leaf guide plate is integrally formed at the tip of the lower fixed plate at the lower side of the tip of the movable blade. It may be provided integrally.

又、枝葉誘導板は、固定板から独立した板体を取り付ける構成でもよい。この実施の形態を図７に示す。図７は別の実施の形態のヘッジトリマにおける可動刃及び固定板の組立状況を示す分解斜視図である。この実施の形態では一対の可動刃４，５は、上側の固定板３に支持されるもので固定板３に取付けられるカバー８にボルト孔８ａを穿設し、可動刃５の下側に配設する枝葉誘導板２３をボルト１９ａ及びナット９ｂを用いて締結する。 Moreover, the structure which attaches the plate body independent from the fixed board may be sufficient as a branch-and-leaf guide plate. This embodiment is shown in FIG. FIG. 7 is an exploded perspective view showing an assembled state of the movable blade and the fixed plate in the hedge trimmer according to another embodiment. In this embodiment, the pair of movable blades 4, 5 are supported by the upper fixed plate 3, and a bolt hole 8 a is formed in the cover 8 attached to the fixed plate 3, and is arranged below the movable blade 5. The branch and leaf guide plate 23 to be provided is fastened using bolts 19a and nuts 9b.

枝葉誘導板２３も、一般切刃４ｂ，５ｂより前方に突出する斜め切欠部２３ｃを形成し、その基部２３ｂにはボルト孔２３ａを穿設する。枝葉誘導板２３はボルト１９ａにスペーサ２０を介在させることで、可動刃４，５から離隔して設置され、これら可動刃４，５が遊動可能となる。 The branch and leaf guide plate 23 also has an oblique notch 23c that projects forward from the general cutting edges 4b and 5b, and a bolt hole 23a is formed in the base 23b. The branch and leaf guide plate 23 is spaced apart from the movable blades 4 and 5 by interposing the spacers 20 on the bolts 19a, so that the movable blades 4 and 5 can move freely.

なお、この実施の形態においても可動刃５の先端部には幅広の先端切刃５ｃを設ける。 In this embodiment as well, a wide tip cutting edge 5c is provided at the tip of the movable blade 5.

独立した板体形式の枝葉誘導板の取付方法は、可動刃が遊動可能で、枝葉を切刃間に誘導することができれば上述した例には限定されず、上側固定板３若しくはカバー８に直接取り付ける構成でもよい。 The attachment method of the branch plate guide plate in the form of an independent plate is not limited to the above example as long as the movable blade can move freely and the branches and leaves can be guided between the cutting blades, and is directly attached to the upper fixed plate 3 or the cover 8. The structure which attaches may be sufficient.

又、このヘッジトリマは可動刃片刃タイプのみならず、両刃タイプでも適用可能である。この実施の形態を図８に示す。図８は可動刃両刃タイプの先端部拡大平面図である。両刃の可動刃３４，３５は、上側固定板３３と下側固定板４３との間に配置されており、一方の可動刃３５の先端部には両側部に幅広の先端切刃３５ｃを設ける。この場合も先端切刃３５ｃは一般切刃３５ｂより前方に突出する切っ先部３５ｄを形成する。 Moreover, this hedge trimmer is applicable not only to a movable blade single blade type but also to a double blade type. This embodiment is shown in FIG. FIG. 8 is an enlarged plan view of the tip of the movable blade double-edged type. The movable blades 34 and 35 of both the blades are disposed between the upper fixed plate 33 and the lower fixed plate 43, and the distal end portion of one movable blade 35 is provided with wide distal cutting blades 35c on both sides. Also in this case, the tip cutting edge 35c forms a cutting edge portion 35d protruding forward from the general cutting edge 35b.

又可動刃３５の下側に位置する下側固定板４３の先端部には一般切刃３４ｂ，３５ｂ及び先端切刃３５ｃより前方に突出する枝葉誘導板４３ｂを設ける。枝葉誘導板４３ｂも切っ先部３５ｄと同様な斜め切欠部４３ｃを形成する。 Further, general cutting edges 34b and 35b and a branch and leaf guide plate 43b projecting forward from the leading edge cutting edge 35c are provided at the distal end portion of the lower fixed plate 43 positioned below the movable blade 35.
