Description

【０００１】
【発明の属する技術分野】
この発明はのこぎりを用いた材料の切断に関するものである。
【０００２】
【従来の技術】
従来、のこぎりを使って材料を切断するには、材料に直線を引きその線に沿ってのこぎりを引いて切断していたが、切断する距離が長い場合などには、のこぎりを持つ手が左右に振れたり斜めに傾いたりして素人には正確に切断することは難しかった。
また、のこぎりを一定角度の面に磁石で吸引してのこぎりを正確に保持する道具はあったが、のこぎりを吸引する磁石が固定されているため、１０センチ程度の短い距離は正確に切断できても、更に長い距離を正確に切断することは困難だった。
また、一定の角度で溝を設けたブロックに材料を当てて、その溝にのこぎりの歯を入れて材料を切断する冶具もあるが、これも長い距離を正確に切断することは出来なかった。
【０００３】
【発明が解決しようとする課題】
本発明は以上のような問題を解決し、長い距離でものこぎりで正確に切断できるようにしようとするものである。
【０００４】
【課題を解決するための手段】
今、その解決手段を図面を追って説明すれば、
（イ）台板１の一端面に沿ってのこぎりの側面をあてる面を有するガイド板２を一定の角度例えば垂直に取り付ける。
（ロ）ガイド板２ののこぎりをあてる面と反対側の面に沿って磁石３が移動するための磁石通路４を設け、その中に磁石３を入れ、磁石通路４の両端にストッパー７及びストッパー８を取り付ける。
以上のようにに構成する。
【０００５】
【発明の実施の形態】
次ぎに本発明の実施の形態を述べると、のこぎりで切断しようとする材料の切断したい線にガイド板２を合わせて置き、台板１を片手あるいは片足でおさえておいてのこぎり５の側面をガイド板２にあてると、のこぎり５は磁石通路４の中にある磁石３によってガイド板２にぴたりと吸い付く。この状態でのこぎり５を引くと、のこぎり５はガイド板２にぴたりを吸い付いたまま材料を切断してゆき、また、のこぎり５をガイド板２に吸い付けている磁石３ものこぎり５の移動に伴って磁石通路４の中を移動するので、のこぎり５を常にガイド板にぴたりと吸けた状態でのこぎりを引くことができ、材料は最初にガイド板を合わせた線のとうりに長い距離でも正確に切断される。
また、磁石３は磁石通路４の端まで移動するとストッパー７あるいはストッパー８にあたり停止するので、磁石通路４から外に飛び出すことはない。
ここで、磁石通路４の形状は、磁石３がガイド板２に沿って自由に移動できるものであれば良く、溝状のものだけでなく例えばレール状のもの等色々な形状が可能である。
また、図２に示すように台板１の底面にガイド板２に対し角度保持棒６を一定の角度例えば直角に取り付ければ、この角度保持棒６を切断しようとする材料の端面にあてることで、より簡単に正確な位置と角度で切断することができる。
更に、図３に示すように、この角度保持棒６をガイド板２に対して角度可変とし、角度保持棒６を角度目盛１０の希望の目盛にあわせて固定ネジ９を締め、角度保持棒６を台板１に固定した後、角度保持棒６を切断しようとする材料の端面にあてて上記のようにのこぎり５で切断すれば、容易に希望の角度で正確に材料を切断することができる。
ここで、角度保持棒６は必ずしも連続的に角度可変でなくても良く、例えば３０度、４５度、９０度等主に使用する角度にだけ段階的に設定可能としてもよい。
更にまた、図４に示すように、台板１とガイド板２との垂直方向の角度を可変とし、ガイド板２を台板１に対し希望の角度に傾けた後、留めネジ１１を締め上記と同様にのこぎりで切断すれば、切断しようとする材料の垂直方向の切断面の角度も容易に希望の角度で切断できる。
【０００６】
【発明の効果】
本発明によれば、日曜大工などにおいて素人でものこぎりを使って簡単に長い材料などを正確に希望の角度で切断することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to cutting a material using a saw.
[0002]
[Prior art]
Conventionally, when cutting a material using a saw, a straight line was drawn on the material and a saw was drawn along the line, but when the cutting distance is long, the hand holding the saw should be It was difficult for a layman to cut accurately by swinging or tilting.
In addition, there was a tool to hold the saw accurately by attracting the saw to the surface at a certain angle with a magnet, but since the magnet for sucking the saw is fixed, it can be cut accurately for short distances of about 10 cm. However, it was difficult to accurately cut longer distances.
There is also a jig that cuts a material by applying a material to a block provided with a groove at a certain angle and inserting a saw tooth into the groove, but also cannot cut a long distance accurately.
[0003]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION The present invention is intended to solve the above-described problems and to make it possible to cut accurately with a saw even at a long distance.
[0004]
[Means for Solving the Problems]
Now, if you explain the solution with reference to the drawings,
(A) A guide plate 2 having a surface to which a side surface of a saw is applied along one end surface of the base plate 1 is attached at a predetermined angle, for example, vertically.
(B) A magnet passage 4 for moving the magnet 3 is provided along the surface of the guide plate 2 opposite to the surface on which the saw is applied, and the magnet 3 is inserted into the magnet passage 4. Stoppers 7 and stoppers are provided at both ends of the magnet passage 4 8 is attached.
The configuration is as described above.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of the present invention will be described. The guide plate 2 is placed on the line to be cut of the material to be cut with a saw, and the side of the saw 5 is held by holding the base plate 1 with one hand or one foot. When applied to the plate 2, the saw 5 is attracted to the guide plate 2 by the magnet 3 in the magnet passage 4. When the saw 5 is pulled in this state, the saw 5 cuts the material while adhering to the guide plate 2, and moves the magnet 5 that is holding the saw 5 to the guide plate 2. As it moves in the magnet passage 4, the saw 5 can be drawn while the saw 5 is constantly sucked into the guide plate, and the material is accurate even over a long distance as the line where the guide plate was first joined. Is cut off.
When the magnet 3 moves to the end of the magnet passage 4, the magnet 3 hits the stopper 7 or the stopper 8 and stops, so that the magnet 3 does not jump out of the magnet passage 4.
Here, the shape of the magnet passage 4 may be any shape as long as the magnet 3 can move freely along the guide plate 2, and various shapes such as a groove-like shape and a rail-like shape are possible.
Also, as shown in FIG. 2, if the angle holding rod 6 is attached to the bottom surface of the base plate 1 at a fixed angle, for example, a right angle with respect to the guide plate 2, the angle holding rod 6 can be applied to the end face of the material to be cut. Can be more easily cut at the correct position and angle.
Further, as shown in FIG. 3, the angle holding rod 6 is made variable in angle with respect to the guide plate 2, and the angle holding rod 6 is tightened with the fixing screw 9 in accordance with a desired scale of the angle scale 10, and the angle holding rod 6 is rotated. Is fixed to the base plate 1, the angle holding bar 6 is applied to the end face of the material to be cut, and cut with the saw 5 as described above, so that the material can be easily cut accurately at a desired angle. .
Here, the angle holding bar 6 does not necessarily need to be continuously variable in angle, and may be set in a stepwise manner only at an angle mainly used, such as 30 degrees, 45 degrees, and 90 degrees.
Furthermore, as shown in FIG. 4, the vertical angle between the base plate 1 and the guide plate 2 is made variable, the guide plate 2 is tilted at a desired angle with respect to the base plate 1, and then the fastening screw 11 is tightened. By cutting with a saw in the same manner as described above, the angle of the vertical cut surface of the material to be cut can be easily cut at a desired angle.
[0006]
【The invention's effect】
ADVANTAGE OF THE INVENTION According to this invention, even a layman can easily cut a long material etc. exactly at a desired angle using a saw even in a DIY.
