Description

【0001】
【発明の属する技術分野】
本発明は、切屑を受け止めるレシーバを備えた手持式芝刈機に関する。
【0002】
【従来の技術及び発明が解決しようとする課題】
特開2000−83475が開示する手持式芝刈機は上下に重なり合う櫛状の切断刃を互いに逆向きに往復角運動させることで草木を刈り込むようになっているが、このような手持式芝刈機で草木を刈ると、切屑はそのまま落下するので、後の清掃が面倒である。
【0003】
また、実開平3−74227が開示する手持式芝刈機は、上下に重なり合う櫛状の切断刃を互いに逆向きに往復直線運動させることで草木を刈り込むようになっており、この切断刃の中央に沿って配置される切屑の捕集部材を備えるが、この捕集部材は切断刃の板状押え板にボルト・ナットにより固着されるので、捕集部材の着脱が不自由であり、また手持式芝刈機の清掃作業の邪魔になる。
【0004】
【課題を解決するための手段】
上記問題点を解決するため、請求項1の発明は、櫛状の切断刃(2)による刈り込みにより生じた切屑を受け止めるレシーバ(5)が形成された手持式芝刈機を採用する。
【0005】
また、請求項2の発明は、櫛状の切断刃(2)による刈り込みにより生じた切屑を受け止めるレシーバ(5)がハウジング(1)に着脱可能に取り付けられた手持式芝刈機を採用する。
【0006】
また、請求項3の発明は、請求項1又は請求項2に記載の手持式芝刈機において、レシーバ(5)の左右縁(5a,5b)が切断刃(2)の左右両側に対応する位置に形成された手持式芝刈機を採用する。
【0007】
【発明の実施の形態】
次に、本発明の実施の形態を図面を参照して説明する。
【0008】
<実施の形態1>
図1乃至図4に示すように、この手持式芝刈機は、ハウジング1と、ハウジング1からその前方に突出する切断刃2とを具備する。
【0009】
ハウジング1は例えば左右二つ割りの割り型を結合させることにより形成される。ハウジング1の後部にはハンドル3が一体的に設けられる。ハンドル3の内側にはON・OFFスイッチのトリガー4が設けられる。図示しないが、ハウジング1の内部には、原動部、伝動部等が収納される。原動部としては例えばモータが用いられ、伝動部としては例えばカム装置が用いられる。ハンドル3を持つ手の指でトリガー4を操作し、ON・OFFスイッチをON・OFF切換えすることにより、モータが起動し又は停止する。
【0010】
切断刃2は、櫛状の上刃2aと同じく櫛状の下刃2bとを重ね合わせたうえで図示しない枢ピンで連結することにより構成される。枢ピンを支点にして上下刃2a,2bが左右に往復角運動すると、櫛状の歯が繰り返し交差して草木を切断する。図示しないが上下刃2a,2bの枢ピンより後方の部分には、それぞれ長孔が形成され、各長孔に上記カム装置の上下のカムが嵌まり込む。上下のカムは位相が180度ずれるように一体化されている。原動部のモータの起動によりカムが回転すると、上下刃2a,2bは互いに反対向きに往復角運動を行い、櫛状の歯間に入る草木を切断する。
【0011】
ハウジング1には、図5及び図6に示すレシーバ5が、図1乃至図4に示すように着脱可能に取り付けられる。
【0012】
レシーバ5は、櫛状の切断刃2による刈り込みにより生じた切屑を受け止めるための捕集具であり、図5及び図6に示すように、手持式芝刈機の左右方向に延びる底板6と、底板6の後部から斜め後方に立ち上がる背板7とを具備する。レシーバ5は例えば樹脂の射出成形、金属板のプレス成形等により望ましくは一体に形成される。底板6及び背板7の中央部にはハウジング1の前部が嵌り込む略U字形の切欠8が形成される。図1乃至図4に示すように、レシーバ5がハウジング1に取り付けられると、底板6、背板7及びハウジング1との間に切屑を受け止める捕集部が形成される。底板6の前端6aは、切断作業に支障を来たさないように切断刃2の櫛状の歯よりややハウジング1側に後退している。
【0013】
この実施の形態では、レシーバ5は次のような着脱手段を介してハウジング1に着脱自在に取り付けられる。
【0014】
すなわち、図5及び図6に示すように、背板7の切欠8に臨む箇所に一対の凹部9が形成され、図1乃至図4に示すように、ハウジング1の左右の側面には各凹部9に嵌まり込む凸部10が形成される。凸部10はハウジング1の左右の側面から水平に突出する丸軸として形成され、凹部9は各凸部10である丸軸が入り込む丸穴として形成される。凹部9である丸穴の下部にはレシーバ5をハウジング1に着脱する際に凸部10を通すための開口9aが形成される。図1乃至図4に示すように、凹凸部9,10の嵌合によりレシーバ5は前後方向に動かないようハウジング1に取り付けられる。また、図5及び図6に示すように、レシーバ5の底板6の後縁から切欠8内へと係止片11が舌状に突出する。図2乃至図4に示すように、この係止片11がハウジング1の底面1aに弾性変形を伴って接触することにより、レシーバ5は凹凸部9,10を支点に上下に回動しないようハウジング1に固定される。
【0015】
このレシーバ5は切断刃2の左右縁よりもさらに外側へと大きく突出するように形成してもよいが、望ましくは図1、図3及び図4に示すように、左右縁5a,5bが切断刃2の左右両側に対応するように形成される。この場合もレシーバ5の左右縁5a,5bは切断刃2の左右両側よりも多少突出するが、その突出量は例えば数mm程度である。芝草等を際刈りする場合、このレシーバ5の左右縁5a,5bをガイドとして図示しないブロック塀等に沿ってスライドさせれば、刈り取り作業が効率化される。
【0016】
次に、この手持式芝刈機の作用について説明する。
【0017】
まず、レシーバ5を切断刃2の下方からハウジング1に近づけて係止片11をハウジング1の底面1aに当て、続いてレシーバ5を後方向にスライドさせ、レシーバ5の凹部9をハウジング1の凸部10に対向させる。そこで、レシーバ5又は係止片11を撓ませて凹部9内に凸部10を嵌め込む。
【0018】
レシーバ5は、図1乃至図4に示すように、凹凸部9,10の嵌合、係止片11のハウジング底面1aへの係止、切欠8内へのハウジング1の挿入等により、ハウジング1に固定される。
【0019】
そこで、手持式芝刈機のハンドル3を持ちトリガー4を引くと、モータが起動し、切断刃2の上下刃2a,2bが左右に往復角運動を行う。この切断刃2を草木に当てることにより、草木が刈り込まれる。
【0020】
刈り込みにより生じた切屑は手持式芝刈機下に落下することなくレシーバ5の底板6と背板7との間の空所に受け止められレシーバ5上に蓄積する。
【0021】
レシーバ5をハウジング1から外すには、レシーバ5を上方向に押し上げるようにしてレシーバ5と係止片11を弾性変形させ、凹凸部9,10を離反させる。続いてレシーバ5をハウジング1の前方へとスライドさせ、係止片11をハウジング1の底面1aから離脱させる。
【0022】
これにより、レシーバ5は手持式芝刈機から取り外され、レシーバ5と手持式芝刈機はそれぞれ清掃等に付される。
【0023】
<実施の形態2>
図7乃至図9に示すように、この実施の形態2では、実施の形態1の場合と異なり、レシーバ5とハウジング1に形成される凹凸部9,10がそれぞれ角穴と角軸により形成される。具体的には、凸部10が板片として形成され、凹部9が板片の嵌まり込む矩形穴として形成される。
【0024】
このように凹凸部9,10が角穴と角軸により形成されるとレシーバ5は上下方向に回動し難くなるので、係止片11は省略可能である。
【0025】
なお、この実施の形態2において実施の形態1における部分と同一部分には同じ符号を付して示すこととしその詳細な説明は省略する。
【0026】
<実施の形態3>
図10乃至図12に示すように、この実施の形態3では、実施の形態1及び実施の形態2の場合と異なり、レシーバ5をハウジング1に取り付けるための凹部9がハウジング1の左右の側面に形成され、凸部10がレシーバ5の切欠8に臨む箇所に形成される。
【0027】
この凹凸部9,10は実施の形態1の場合のように丸穴及び丸軸とすることもできる。係止片11は必要に応じて設けることが可能である。
【0028】
なお、この実施の形態3において実施の形態1又は実施の形態2における部分と同一部分には同じ符号を付して示すこととしその詳細な説明は省略する。
【0029】
<実施の形態4>
図13及び図14に示すように、この実施の形態4では、実施の形態1乃至実施の形態3の場合と異なり、ハウジング1の底板部1bがハウジング本体に対して着脱自在に形成され、レシーバ5がこのハウジング1の底板部1bと一体的に形成される。ハウジング1の底板部1bをハウジング本体に対し着脱するために、底板部1bの左右縁と後縁にはそれぞれ嵌合片12とバネ片13が設けられる。
【0030】
ハウジング1の底板部1bがハウジング本体に嵌め込まれると同時にレシーバ5がハウジング1に装着され、ハウジング1の底板部1bがハウジング本体から取り外されると同時にレシーバ5がハウジング1から除去される。
【0031】
なお、この実施の形態4において実施の形態1乃至実施の形態3における部分と同一部分には同じ符号を付して示すこととしその詳細な説明は省略する。
【0032】
<実施の形態5>
図15及び図16に示すように、この実施の形態5では、実施の形態1乃至実施の形態4の場合と異なる着脱手段を介してレシーバ5がハウジング1に着脱自在に取り付けられる。
【0033】
すなわち、背板7の切欠8に臨む左右の二箇所からハウジング1の左右の側面に沿うように取付板14が後方へと突出し、これらの取付板14がハウジング1の側面に取付用ネジ15で固定される。取付用ネジ15は図示しないネジ棒につまみを固定してなるもので、ネジ棒が取付板14を貫通しハウジング1の側面に形成された図示しないネジ孔に螺合する。取付用ネジ15が締め付けられることによりレシーバ5は取付板14を介しハウジング1に固定され、取付用ネジ15が緩められることによりレシーバ5はハウジング1から取り外される。
【0034】
なお、実施の形態5の場合には、例えば取付用ネジ15の箇所を支点にして、レシーバ5を回動し、レシーバ5の取付角度を変更することにより、芝草等の刈り込み高さを調整することも可能である。また、実施の形態5の場合には、取付板14に形成された取付用ネジ15の貫通穴を上下方向の長穴に形成し、レシーバ5の取付位置を上下に位置変更可能に形成すると、芝草等の刈り込み高さをより容易に調整可能である。
【0035】
なお、この実施の形態5において実施の形態1乃至実施の形態4における部分と同一部分には同じ符号を付して示すこととしその詳細な説明は省略する。
【0036】
<実施の形態6>
図17及び図18に示すように、この実施の形態6では、実施の形態1乃至実施の形態5の場合と異なる着脱手段を介してレシーバ5がハウジング1に着脱自在に取り付けられる。
【0037】
すなわち、レシーバ5の底板6の後縁から切欠8内へと舌状に突出する係止片11がハウジング1の底面1aに取付ネジ16により固定される。取付ネジ16が締め付けられることによりレシーバ5はハウジング1に固定され、取付ネジ16が緩められることによりレシーバ5はハウジング1から取り外される。
【0038】
なお、この実施の形態6において実施の形態1乃至実施の形態5における部分と同一部分には同じ符号を付して示すこととしその詳細な説明は省略する。
【0039】
その他、上記各実施の形態において、レシーバ5は手持式芝刈機のハウジング1と成形当初より一体的に形成することも可能である。
【0040】
【発明の効果】
請求項1に係る発明によれば、櫛状の切断刃による刈り込みにより生じた切屑を受け止めるレシーバが形成された手持式芝刈機であるから、レシーバにより切屑を受け止めつつ刈り込み作業を行うことで後の切屑等の清掃が不要になる。また、レシーバを形成したことにより、延長コードが切断刃に接触しにくくなるので、誤って延長コードを切断してしまうことがなくなると共に、レシーバが、ハンドルを握持した作業者の手のガードとしても機能し、作業者は安心して刈り込み作業を行うことができる。
【0041】
請求項2に係る発明によれば、櫛状の切断刃による刈り込みにより生じた切屑を受け止めるレシーバがハウジングに着脱可能に取り付けられた手持式芝刈機であるから、レシーバにより切屑を受け止めつつ刈り込み作業を行うことで後の切屑等の清掃が不要になり、また、レシーバをハウジングから工具等を使用することなく速やかに取り外すことで手持式芝刈機の保守、点検を簡易に行うことができる。
【0042】
請求項3に係る発明によれば、請求項1に記載の手持式芝刈機において、レシーバの左右縁が切断刃の左右両側に対応する位置に形成された手持式芝刈機であるから、芝草等の際刈りを行う場合にレシーバの左右縁をガイドとして使用することができ、刈り取り作業を効率よく行うことができる。
