Description

【０００１】
【発明の属する技術分野】
本発明は、軒樋を所定の寸法に電動鋸で切断するときに用いる軒樋の切断治具の構造に関するものである。
【０００２】
【従来の技術】
従来、この種の軒樋の切断治具は軒樋の長手方向と直交する幅方向に亙って軒樋の外周または内周に沿って被嵌し得る切断治具本体の周方向の端部に軒樋の幅方向の両端の耳部に嵌合し得る耳嵌合部を設け、軒樋の長手方向と平行な方向である切断治具本体の幅方向の両側のうち一方の側端縁に工具をガイドするガイド面を設けて形成してある（例えば、特許文献１参照）。この切断治具は軒樋の切断する位置で軒樋の外周または内周に沿わせると共に耳嵌合部を軒樋の耳部に嵌合して軒樋の取り付け、切断治具のガイド面に沿わせて鋸で切断することで軒樋を切断するようになっている。
【０００３】
切断治具Ａ′を軒樋１の外面に被せて切断する場合、図６に示すようにおこなている。切断治具Ａ′は図６（ａ）に示すように軒樋１の外面に沿う切断治具本体２′の周方向の両端に耳嵌合部３′を設けてあり、切断治具本体２′の一方の側端縁に沿ってガイド面４′を設けてある。この切断治具Ａは図６（ａ）に示すように切断治具本体２′が軒樋１の外面に沿うように被せられると共に耳嵌合部３′が軒樋１の耳部５に嵌合して軒樋１に取り付けられ、図６（ｂ）に示すように軒樋１の切断する位置にガイド面４′を沿わせて罫書き具６にガイド面４′に沿って罫書き線７が入られ、図６（ｃ）に示すように金きり鋸のような手動鋸８をガイド面４′にてガイドして切断することで罫書き線７に沿って切断されるようになっている。
【０００４】
手動鋸８に替えて電動鋸９で切断する場合、図６（ｂ）のように罫書き線７を入れた後、図７（ａ）のようにガイド代の寸法ｘだけ切断治具Ａ′を軒樋１に対してスライドさせられ、図７（ｂ）に示すように電動鋸９のベース板１０の側端縁をガイド面４′に沿わせると共に電動鋸９の回転刃１１を罫書き線７に沿わせて回転刃１１にて軒樋１を切断していた。

【発明が解決しようとする課題】
ところで、手動鋸８で切断するより電動鋸９で切断する方が労力を要せず、且つ速く切断することができるのであるが、電動鋸９は回転刃１１を動力で回転駆動して切断するものであるため、回転刃１１を軒樋１に当てて罫書き線７に沿って切断するとき、電動鋸９のベース板１０の側端縁をガイド面４′に沿わせるだけでは電動鋸９が上下左右に振動して切断位置がずれやすく、罫書き線７に沿って正確に切断できないおそれがある。
【０００７】
本発明は上記の点に鑑みてなされたものであり、電動鋸で切断するときでも電動鋸を確実にガイドして正確に軒樋を切断できる軒樋の切断治具を提供することを課題とするものである。
【０００８】
【課題を解決するための手段】
上記課題を解決するために本発明の軒樋の切断治具Ａは、軒樋１の長手方向と直交する幅方向に亙って軒樋１の外周に被嵌し得る切断治具本体２の周方向の端部に軒樋１の幅方向の両端の耳部５に嵌合し得る耳嵌合部３を設け、軒樋１の長手方向と平行な方向である切断治具本体２の幅方向の両側の側部にガイド溝４を切断治具本体２の周方向に設け、電動鋸９のベース板１０に装着した被ガイド部材１３の両側の被ガイド片１４をガイド溝４に挿入してガイド溝４に沿って摺動させる得るようにしたことを特徴とする。切断治具Ａの切断治具本体２を軒樋１の外面に沿わせると共に耳嵌合部３を軒樋１の耳部５に嵌合して切断治具Ａを軒樋１にセットし、電動鋸９の被ガイド部材１３の両側の被ガイド片１４を両側のガイド溝４に挿入し、ガイド溝４に挿入した被ガイド片１４をガイド溝４に沿って摺動させることにより電動鋸９で切断できる。このようにガイド溝４に挿入した被ガイド片１４をガイド溝４に沿って摺動させることにより電動鋸９が振動しないようにガイドして切断でき、軒樋１を所定の切断位置で正確に切断することができる。このとき両側の被ガイド片１４を両側のガイド溝４でガイドするために電動鋸９が左右に振動しないようにガイドできると共に被ガイド片４がガイド溝４に沿ってスムーズに摺動するようにガイドできて軒樋１を所定の切断位置で正確に切断できると共にスムーズに切断できる。
【０００９】
また横片１５ａと縦片１５ｂとからなる断面略逆Ｌ字状のガイド部１５を切断治具本体２の幅方向の両側の側部に切断治具本体２の周方向に設けて切断治具本体２とガイド部１５との間にガイド溝４を設けたことを特徴とすることも好ましい。ガイド溝４に被ガイド片１４を挿入して被ガイド片１４を摺動させるとき、横片１５ａにて上下に振動しないように規制できると共に縦片１５ｂにて左右に振動しないように規制でき、電動鋸９が上下左右に振動するのを確実に規制して電動鋸９で一層正確に切断できる。
【００１０】
また両側のガイド溝４間で切断治具本体２に電動鋸９の回転刃１１を挿通し得る刃挿通溝１６を切断治具本体２の周方向に穿設したことを特徴とすることも好ましい。両側のガイド溝４に沿って両側の被ガイド片１４がガイドされるが、この間に位置する刃挿通溝１６に電動鋸９の回転刃１１を挿通して切断でき、軒樋１の切断がスムーズにできる。
【００１１】
また切断治具本体２の周方向の両端から耳嵌合部３より周方向に突出するように連出片１７を連出し、刃挿通溝１６を連出片１７に至るまで穿設したことを特徴とすることも好ましい。刃挿通溝１６に挿通した電動鋸９の回転刃１１を軒樋１の幅方向の全長より長い長さに亙って挿通でき、軒樋１の耳部５まで確実に切断することができる。
【００１２】
【発明の実施の形態】
軒樋１は本例の場合、角型であり、図１に示すように前壁１ａと底壁１ｂと後壁１ｃとを有し、前壁１ａと底壁１ｂとの間に凹曲部１ｄを有しており、前壁１ａの端部及び後壁１ｃの端部に長手方向に亙って耳部５を有している。
【００１３】
軒樋の切断治具Ａの切断治具本体２は帯板状であって、図２に示すように軒樋１の外面に沿う形状にしてあり、前壁部２ａと底壁部２ｂと後壁部２ｃとを有し、前壁部２ａと底壁部２ｂとの間に凹曲部２ｄを有している。前壁部２ａ及び後壁部２ｃの端部に耳部５に嵌合し得る耳嵌合部３を有している。切断治具本体２の前後方向と平行な両側の側部には周方向の略全長に亙るようにガイド部１５を設けてある。このガイド部１５は横片１５ａと縦片１５ｂで断面略逆Ｌ字状に形成されており、このガイド部１５と切断治具本体２の外面との間にガイド溝４が形成されている。また切断治具本体２の前壁部２ａや後壁部２ｃの端部から耳嵌合部３を越えて突出するように連出片１７を連出してある。切断治具本体２の両側のガイド部４間には切断治具本体２の周方向に刃挿通溝１６が穿設されるのであるが、刃挿通溝１６は耳嵌合部３を越えて連出片１７に至るまで穿設してある。
【００１４】
電動鋸９は図４に示すように電動鋸本体９ａにモータや充電池等を設けてあり、電動で回転駆動される回転刃１１を有している。また電動鋸本体９ａには矩形の平板状のベース板１０を設けてあり、ベース板１０に設けたスリット１２に回転刃１１を挿通してある。ベース板１０の周縁には立ち上がり縁２０を設けてあるが、電動鋸９で切断するとき前となる前方の位置に両側の立ち上がり縁２０には挿通穴２１を穿孔してあり、両側の挿通穴２１間の部分の突片２３に取り付けねじ具２２を螺合してある。
【００１５】
電動鋸９で切断するときに電動鋸９のベース板１０に取り付ける被ガイド部材１３は図５に示すように構成されている。左右方向に細長い取り付け板１３ａの一端から下面側に折り返すように取り付け板１３ａと平行に中間板１３ｂを一体に設けてあり、取り付け板１３ａの長手方向の中間の位置で中間板１３ｂを下方に凸曲させるように曲げて凸曲部１３ｃを設けてあり、凸曲部１３ｃの下面に摺接板１３ｄを一体に装着してある。摺接板１３ｄの長手方向の両端は凸曲部１３ｃより突出させてあり、この両側の突出した部分を被ガイド片１４としてある。この被ガイド部材１３を電動鋸９に取り付ける場合、図４（ａ）に示すように被ガイド部材１３の取り付け板１３ａがベース板１０の両側の挿通穴２１に挿通されてベース板１０が取り付け板１３ａと中間板１３ｂで挟まれ、図４（ｂ）に示すように取り付けねじ具２２を締め付けることで取り付け板１３ａが押さえられる。
【００１６】
しかして、軒樋１を切断する場合、次のように行う。裏返しにした軒樋１の切断する位置の近傍に切断治具Ａを配置し、切断治具本体２を軒樋１の外面に沿わせるように被せ、耳嵌合部３を軒樋１の耳部５に嵌合して軒樋１に切断治具Ａを取り付ける。切断治具Ａを取り付けた状態で刃挿通溝１６を軒樋１の切断位置に合わせる。次いで電動鋸９の回転刃１１を回転駆動して軒樋１を切断するのであるが、このとき、刃挿通溝１６に電動鋸９の回転刃１１を挿通し、被ガイド部材１３の両側の被ガイド片１４を図３に示すように両側のガイド溝４に挿入し、両側ガイド溝４に対して両側の被ガイド片１４を、刃挿通溝１６に対して回転刃１１を摺動させながら電動鋸９を移動させて回転刃１１にて軒樋１を軒樋１の幅方向全長に亙って切断する。このとき被ガイド片１４の先端を縦片１５ｂに摺接させて移動させることにより、軒樋１を刃挿通溝１６に沿わせて切断することができる。
【００１７】
被ガイド片１４をガイド溝４に対して摺動させるとき、ガイド部１５の横片１５ａにて規制されて電動鋸９が上下に振動するのが防止されると共に縦片１５ａにて規制されて左右に振動するのが防止され、所定の切断位置で正確に切断できる。また両側のガイド溝４で両側の被ガイド片１４がガイドされることにより、電動鋸９が左右に振動しないようにガイドできると共に電動鋸９がスムーズに移動するようにガイドでき、電動鋸９により正確に切断できると共に電動鋸９でスムーズに切断することができる。両側のガイド溝４に沿って両側の被ガイド片１４がガイドされるが、この間に位置する刃挿通溝１６に電動鋸９の回転刃１１を挿通して切断でき、軒樋１の切断がスムーズにできる。また刃挿通溝１６に挿通した電動鋸９の回転刃１１を軒樋１の幅方向の全長より長い長さに亙って挿通でき、軒樋１の耳部５まで確実に切断することができる。

【The invention's effect】
The invention according to claim 1 of the present invention provides a cutting jig body which can be fitted on the outer periphery of an eaves gutter in a width direction orthogonal to the longitudinal direction of the eaves gutter. Providing ear fitting portions that can be fitted to the ear portions at both ends, and forming guide grooves on both sides in the width direction of the cutting jig body in a direction parallel to the longitudinal direction of the eaves gutter. The guide pieces on both sides of the guided member mounted on the base plate of the electric saw are inserted into the guide grooves and can be slid along the guide grooves. The cutting jig is set on the eaves gutter by fitting the ear fitting part to the eaves gutter, and the guide pieces on both sides of the guided member of the electric saw are guided along both sides of the eaves gutter. And the guide piece inserted in the guide groove can be cut by an electric saw by sliding along the guide groove. By sliding the guided piece inserted along the guide groove along the guide groove, the electric saw can be cut and guided so as not to vibrate, and the eaves gutter can be cut accurately at a predetermined cutting position. Since the guided pieces on both sides are guided by the guide grooves on both sides, the electric saw can be guided so that it does not vibrate to the left and right, and the guided pieces can be guided so that they slide smoothly along the guide grooves, and the eaves gutter is specified. Can be cut accurately and smoothly at the cutting position.
[0019]
According to a second aspect of the present invention, in accordance with the first aspect, a guide part having a substantially inverted L-shaped cross-section comprising a horizontal piece and a vertical piece is provided on both sides of the cutting jig main body in the width direction. Since the guide groove is provided between the cutting jig body and the guide part by being provided in the circumferential direction of the main body, when inserting the guided piece into the guide groove and sliding the guided piece, The vibration can be restricted so as not to vibrate, and the vertical piece can be restricted so as not to vibrate left and right. The vibration of the electric saw can be surely controlled so as to be able to cut more accurately by the electric saw.
[0020]
According to a third aspect of the present invention, in the first or second aspect, a blade insertion groove through which the rotary blade of the electric saw can be inserted into the cutting jig body between the guide grooves on both sides is provided. The guide pieces on both sides are guided along the guide grooves on both sides, but can be cut by inserting the rotary blade of the electric saw into the blade insertion groove located between them, and cutting the eaves gutter It can be done smoothly.
[0021]
According to a fourth aspect of the present invention, in the third aspect, the extension piece is extended from both ends of the cutting jig body in the peripheral direction so as to protrude in the peripheral direction from the ear fitting portion, and the blade insertion groove is extended. Since the drilling is made up to the piece, the rotary blade of the electric saw inserted through the blade insertion groove can be inserted over a length longer than the entire length of the eaves gutter in the width direction, and it is reliably cut to the ears of the eaves gutter. Is what you can do.
