【０００１】
【発明の属する技術分野】
本発明は、長尺の被切断物を切断する為の切断装置に関するものである。
【０００２】
【従来の技術及び発明が解決しようとする課題】
従来から、例えば屋根に配設される雪止め構造を構成する断面Ｌ字状のアングル部材（以下、Ｌ型アングル）を切断する為の切断装置（以下、従来例）が提案されている。
【０００３】
この従来例は、Ｌ型アングルの所定位置に被嵌連結し得る被嵌連結部に、被切断物を係合配設し得る係合部と、この係合部の対向位置に設けられ、該係合部に対して接離移動し得る移動部とを設け、この移動部を係合部に接近移動させた際、移動部と係合部とでＬ型アングルを挟持切断し得るように構成されたものである。
【０００４】
ところで、この従来例は、被嵌連結部をＬ型アングルに被嵌させる場合、この被嵌連結部に対してＬ型アングルをその端部から挿入して切断したい所定位置までスライドさせることでセットしなければならないが、これは切断したい位置がＬ型アングルの端部であればそれ程問題にはならないものの、Ｌ型アングルの途中位置（中央位置）を切断しようとする場合には、切断したい所定位置まで被嵌連結部をセットする作業が煩わしくて非常に作業能率が悪く、しかも、作業場所が狭かった場合には尚更厄介である（場所によっては使えない場合もあり得る。）などの問題点がある。
【０００５】
本発明は、上述の問題点に解決する従来にない作用効果を発揮する画期的な切断装置を提供する。
【０００６】
【課題を解決するための手段】
添付図面を参照して本発明の要旨を説明する。
【０００７】
長尺の被切断物１の所定位置に被嵌連結し得る被嵌連結部２に、被切断物１を係合配設し得る係合部３と、この係合部３の対向位置に設けられ、該係合部３に対して接離移動し得る移動部４とを設け、この移動部４にラチェット機構やリンク機構などの作動機構５を介して作用腕となる腕部６を連設し、この腕部６の往復操作により移動部４を係合部３に接近移動させた際、移動部４と係合部３とで被切断物１を挟持切断し得るように構成された切断装置であって、前記被嵌連結部２は、対向位置に配される対向部材７，８を前記被切断物１に対して挟み込んだ状態で被嵌し得るように設けて構成されており、この対向部材７，８の対向する一の部位同士は枢着され、この枢着部９を支点に擺動させることで他の部位同士が開放するように設けて、前記被切断物１の所定位置に対して被切断物１の長さ方向と直交する巾方向から被嵌し得るように前記被嵌連結部２を構成したことを特徴とする切断装置に係るものである。
【０００８】
また、前記係合部３と移動部４との対向間隔を被切断物１のサイズに合わせて可変自在に設けたことを特徴とする請求項１記載の切断装置に係るものである。
【０００９】
【発明の実施の形態】
好適と考える本発明の実施の形態（発明をどのように実施するか）を、図面に基づいてその作用効果を示して簡単に説明する。
【００１０】
本発明は、例えば長尺の被切断物１を切断する際、この被切断物１の所定位置に被嵌連結部２を被嵌連結して、被切断物１を係合部３に係合配設し、この状態で腕部６を往復操作することで移動部４を係合部３に接近移動させると、移動部４と係合部３とで被切断物１は挟持切断される。
【００１１】
従って、腕部６を往復操作させるだけで被切断物１を確実且つ良好に切断することができ、例えば本発明に係る切断装置を現場に持ち込み、その場で良好な切断作業が行えることになる。
【００１２】
ところで、本発明は、被嵌連結部２は、対向位置に配される対向部材７，８を前記被切断物１に対して挟み込んだ状態で被嵌し得るように設けて構成されており、この対向部材７，８の対向する一の部位同士は枢着され、この枢着部９を支点に擺動させることで他の部位同士が開放するように設けて、前記被切断物１の所定位置に対して被切断物１の長さ方向と直交する巾方向から被嵌し得るように構成されている。
【００１３】
この構成は、従来から取り扱いが困難とされてきた長尺の被切断物１の切断における作業能率の飛躍的な向上と高精度な切断作業の達成に貢献する。
【００１４】
即ち、仮に被嵌連結部が開放しない構成であった場合、この被嵌連結部に対して被切断物１をその端部から挿入して切断したい所定位置までスライドさせることでセットしなければならならず、非常に作業性が悪く、作業環境にも影響され易いなどの問題点が生じることになるが、この点、本発明は、被嵌連結部２が被切断物１の所定位置に対して被切断物１の長さ方向と直交する巾方向から被嵌し得るように構成されているから、被切断物１の切断したい所定位置にそのまま被嵌連結部２を被嵌させることができ、よって、被切断物１の切断作業が簡易且つ迅速に行えることになるから、長尺の被切断物１の切断作業における作業能率が飛躍的に向上し得ることになり、しかも、この被嵌連結部２が開放することで、被切断物１の切断する位置の確認が非常に行い易くなるから、切断したい位置を確実に切断し得る高精度な切断作業が達成されることになる。
【００１５】
また、係合部３と移動部４との対向間隔を被切断物１のサイズに合わせて可変自在に設けたから、常に良好な切断作業が行えることになる。
【００１６】
【実施例】
本発明の具体的な実施例について図面に基づいて説明する。
【００１７】
本実施例は、長尺の被切断物１（Ｌ型アングル）を切断する為のものである。
【００１８】
尚、本実施例は、長尺の被切断物１を切断する為の切断装置を、Ｌ型アングルを切断する専用の切断装置としているが、本実施例の特性を発揮し得る構成であればその適用範囲は多岐に亙るものである。
【００１９】
具体的には、図１に図示したように下部に接地部１０ａを設けた棒状本体１０の先端部に被切断物１の所定位置に被嵌連結し得る被嵌連結部２を設けている。
【００２０】
この被嵌連結部２は、図１〜４に図示したように上下対向位置に配される対向部材７，８で構成されている。
【００２１】
この対向部材７，８のうち、下方対向部材８は、その基端部を棒状本体１０の先端位置に付設され、上方対向部材７は、その基端部を下方対向部材８の対向基端部と枢着されて擺動自在に設けられており、この枢着部９を支点に上方対向部材７を擺動させることで、被嵌連結部２の前方、即ち、上方対向部材７の先端部と下方対向部材８の先端部とが開放するように構成されている。
【００２２】
従って、被嵌連結部２は、その前方位置が上下に開閉して被切断物１の所定位置を挟み込んだ状態で被嵌し得るように構成されており、実際に被嵌させる場合には、被切断物１の所定位置（切断した位置）に対して被切断物１の長さ方向と直交する巾方向から被嵌し得ることになる。
【００２３】
また、被嵌連結部２は、上方対向部材７の開放擺動を阻止する開放阻止機構１１が設けられている。
【００２４】
この開放阻止機構１１は、図１〜５に図示したように上方対向部材７の先端面部に垂設される係止部材１２と、この係止部材１２の先端係止部１２ａが係止する下方対向部材８の先端面部に設けられた係止段部１３とで構成されており、この係止部材１２の先端係止部１２ａが係止段部１３に係止している際には被嵌連結部２は開放方向には開放せず、確実に被切断物１に対する挟み込んだ被嵌連結状態が維持されることになる。また、この係止部材１２を回動させて係止段部１３に対する係止を解除して、上方対向部材７を上方へ擺動させることで被嵌連結部２は開放し得ることになり、この状態で被切断物１の配設及び取り出しが可能となる。符号１４は係止部材１２を係止段部１３へ係止する方向へ付勢する板バネである。
【００２５】
また、係止部材１２は、その上端部に連設される昇降機構を介して上下方向（図５中ａ方向）に移動自在に設けられている。
【００２６】
この昇降機構は、上方対向部材７の先端突部７ａに貫通するボルト状部材１５と、このボルト状部材１５に螺着されるナット状部材１６とで構成されており、このボルト状部材１５は、その下端部には係止部材１２が回動自在に枢着されるボックス状の連結部材１８が吊り下げ状態に設けられ、その上端部にして先端突部７ａの上面から突出する部位には前記ナット状部材１６が螺着されるネジ棒部１５ｂが設けられている。符号１７は常時下方へ付勢する発条である。
【００２７】
従って、ナット状部材１６を回動（螺動）させてボルト状部材１５を引上げることで、係止部材１２は上昇することになり係止段部１３への係止度合いを強めることができ、一方、これとは反対方向にナット状部材１６を回動させてボルト状部材１５を下げることで、係止部材１２は降下することになり係止段部１３への係止度合いを弱めることができる。
【００２８】
この構成は、係止部材１２における係止段部１３への係止度合いの調整を行えるようにする為の構成であるのは勿論、後述する係合部３と移動部４とで挟持される被切断物１のサイズ（厚み）に対応して該係合部３と移動部４との対向間隔を可変し得るようにするための構成でもあり、実際に切断しようとする際には、常に係合部３に係合配設された被切断物１の上面に移動部４が当接した状態から切断作業を始めることができることになる。
【００２９】
また、被嵌連結部２には、被切断物１を係合配設し得る係合部３と、この係合部３の対向位置に設けられ、該係合部３に対して接離移動し得る移動部４とを設け、この移動部４を係合部３に接近移動させた際、移動部４と係合部３とで被切断物１を挟持切断し得るように構成されている。
【００３０】
係合部３は、被嵌連結部２に係る下方対向部材８の上面部中央位置にＶ字状の凹部３を形成して構成されており、断面Ｖ字状の被切断物１の外面を係合配設し得るように構成されている。この構成から被切断物１は切断の際において前後方向にスライドすることはなく安定保持されることになる。
【００３１】
移動部４は、適宜な金属板製の移動体４を設けて構成されており、この移動体４の下端部は断面Ｖ字状の被切断物１の内面に合わせたＶ字状に形成されている。
【００３２】
また、移動体４は、ラチェット機構５から成る作動機構５を介して作用腕となる腕部６が連設され、この腕部６の往復操作により移動部４を係合部３に接近移動し得るように構成されている。
【００３３】
具体的には、移動体４は、図５〜１０に図示したように上方対向部材７に形成されたスライド凹部７ｂ内を上下方向にスライド移動自在となるように配設されている。
【００３４】
また、この移動体４の側部には回転体１９が配設されており、この回転体１９は上方対向部材７を横断する回転軸２０を介して回転自在に設けられ、この回転軸２０には該回転軸２０の軸芯Ｌ１と異なる軸芯Ｌ２を有する鍔状の偏心部２１が繞設され、この偏心部２１は移動体４に設けた正面視方形状の貫通部４ａ内を左右移動し得るスライド部材２２の円形貫通孔２２ａ内で自転回動自在に設けられている。
【００３５】
従って、回転体１９を回動させることにより回転軸２０が回動すると、偏心部２１がスライド部材２２の円形貫通孔２２ａ内で自転回動し、この回転に伴いスライド部材２２が左右方向にスライドしつつ、この偏心部２１が偏心している分だけ移動体４は上下方向に強制的に移動することになる（図７〜９参照）。
【００３６】
また、この回転体１９は、その周面にして放射方向（４５°ごと）に複数の凹部１９ａが形成されると共に、作用椀となる杆状の腕部６の先端連結部６ａが被嵌連結されており、この先端連結部６ａの内面には各凹部１９ａに係止し得る突没体２３が設けられている。符号６ｂは腕部６の過度回動を防止する回動阻止突起である。
【００３７】
この突没体２３は、発条２４により常時凹部１９ａに係止する方向に付勢されており、その先端係止部分はテーパー面に形成されており、よって、腕部６の往復動は回転体１９を一方向にのみしか回動できないように構成され（これがラチェット機構５である。）、腕部６の一回の往復動は回転体１９を約４５°回転させることになる。符号２５は腕部６を上方に回動させた際に回転体１９が回転するのを防止する回転防止部材、２６は回転体１９を強制的に回動させる回転ハンドルである。
【００３８】
以上の構成から、腕部６の往復動を繰り返し行うことで、移動部４は係合部３に対して接離移動し得るように構成され、腕部６を下方に回動させた際に移動部４は接離移動する。
【００３９】
本実施例は上述のように構成したから、例えば長尺の被切断物１を切断する際、この被切断物１の所定位置に被嵌連結部２を被嵌連結して、被切断物１を係合部３に係合配設し、この状態で腕部６を往復操作することで移動部４を係合部３に接近移動させると、移動部４と係合部３とで被切断物１は挟持切断される。
【００４０】
よって、本実施例によれば、腕部６を往復操作させるだけで被切断物１を確実且つ良好に（楽に）切断することができ、例えば本発明に係る切断装置を現場に持ち込み、その場で良好な切断作業が行えることになり、しかも、被嵌連結部２が被切断物１の所定位置に対して被切断物１の長さ方向と直交する巾方向から被嵌し得るように構成されているから、被切断物１の切断したい所定位置にそのまま被嵌連結部２を被嵌させることができ、よって、被切断物１の切断作業が簡易且つ迅速に行えることになるから、長尺の被切断物１の切断作業における作業能率が飛躍的に向上し得ることになり、しかも、この被嵌連結部２が開放することで、被切断物１の切断する位置の確認が非常に行い易くなるから、切断したい位置を確実に切断し得る高精度な切断作業が達成されることになる。
【００４１】
また、本実施例は、係合部３と移動部４との対向間隔を被切断物１のサイズに合わせて可変自在に設けたから、常に良好な切断作業が行えることになる。
【００４２】
尚、本発明は、本実施例に限られるものではなく、各構成要件の具体的構成は適宜設計し得るものである。
【００４３】
【発明の効果】
本発明は上述のように構成したから、長尺の被切断物の切断における作業能率の飛躍的な向上と高精度な切断作業が達成されるなど極めて商品価値の高い画期的な切断装置となる。
【００４４】
また、請求項２記載の発明においては、常に良好な切断作業が行えることになるなど極めて商品価値の高い画期的な切断装置となる。

[0010]
In the present invention, for example, when cutting a long workpiece 1, the fitting connection portion 2 is fitted and connected to a predetermined position of the workpiece 1, and the workpiece 1 is engaged with the engagement portion 3. When the moving unit 4 is moved closer to the engaging unit 3 by reciprocating the arm unit 6 in this state, the workpiece 1 is nipped and cut by the moving unit 4 and the engaging unit 3.
[0011]
Therefore, the workpiece 1 can be reliably and satisfactorily cut simply by reciprocating the arm 6. For example, the cutting device according to the present invention can be brought into the field and a good cutting operation can be performed on the spot. .
[0012]
By the way, in the present invention, the fitted connecting portion 2 is configured so as to be fitted in a state where the opposed members 7 and 8 arranged at the opposed positions are sandwiched with respect to the workpiece 1, The opposing parts of the opposing members 7 and 8 are pivotally attached to each other, and the pivoting part 9 is pivoted on a fulcrum so that the other parts are opened, and the predetermined position of the workpiece 1 is set. It is comprised so that it can fit with respect to the width direction orthogonal to the length direction of the to-be-cut | disconnected object 1 with respect to.
[0013]
This configuration contributes to a dramatic improvement in work efficiency and achievement of high-precision cutting work in cutting long objects 1 that have been difficult to handle.
[0014]
In other words, if the fitted connecting portion is not opened, it must be set by inserting the workpiece 1 into the fitted connecting portion from its end and sliding it to a predetermined position to be cut. However, the workability is very poor and problems such as being easily influenced by the work environment will occur. However, in this respect, the present invention is such that the fitting connecting portion 2 is located at a predetermined position of the workpiece 1. Since it is configured so that it can be fitted from the width direction orthogonal to the length direction of the workpiece 1, the fitting connecting portion 2 can be fitted as it is at a predetermined position where the workpiece 1 is to be cut. Therefore, since the cutting work of the workpiece 1 can be performed easily and quickly, the work efficiency in the cutting work of the long workpiece 1 can be dramatically improved. The to-be-cut object 1 is cut | disconnected by the connection part 2 opening. Since confirmation of location is very easily performed, high-precision cutting operation is to be achieved which can reliably cut the position to be cut.
[0015]
In addition, since the facing interval between the engaging portion 3 and the moving portion 4 is provided to be variable according to the size of the workpiece 1, a good cutting operation can always be performed.
