えられている。<Prior Art> A saw used for wood processing, lumbering, etc. is provided with appropriate teeth corresponding to its application. This is because the wood that the saw is trying to cut has an uneven texture, and the saw to be drawn in a direction parallel to the wood's wood (fibers) has vertical teeth, a right angle to the wood, or a direction crossing the wood. The pulling saw is equipped with lateral pulling teeth.
この発明は、上記各種の鋸のうちの縦引き歯を備える手
引き鋸の改良に向けられている。The present invention is directed to an improvement of a hand-operated saw provided with a vertical hauling tooth among the above-mentioned various saws.

る。By the way, saw blades have a sawing function to cut wood fibers into chips or sawdust, and a chip removing function to discharge the generated chips to the outside of the cut. is doing. In order for the saw to be light and well cut, it is necessary to have saw teeth that can sufficiently perform these two functions. Further, in vertical pulling teeth, since it is necessary to increase the function of removing chips, conventionally, a lower blade that is perpendicular to the sawing direction is provided, and the structure is such that chips can be removed efficiently. .

ない等の欠点があった。<Problems to be Solved by the Invention> However, in the conventional vertical pulling teeth, since the function of removing chips by the lower blade is enhanced, the function of sawing is insufficient and the sharpness is not sufficient. There was a drawback that there is. In particular, when cutting wet wood, there are drawbacks such as the vertical pulling teeth being caught without cutting the grain, or even if it can be cut, the sawing work cannot be performed lightly and lightly. It was
そこでこの発明は、新規でかつ切れ味の良い縦引き用手
引き鋸を提供することを目的とする。SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a novel hand-drawing saw for vertical pulling which has a good sharpness.

り、鋸断の機能が高められている。<Operation> According to the present invention, the upper end of the second vertical pulling tooth is formed on the tip side surface thereof, and the top of the second vertical pulling tooth has a sharp pointed shape or a shape similar thereto. There is. Therefore, unlike the first vertical pulling teeth, the sawing function is enhanced by the top of the second vertical pulling teeth.
また、切り屑排除の機能は、従来通り、第１縦引き歯に
よって十分に果たされている。Further, the function of removing the chips is sufficiently fulfilled by the first vertical pulling teeth as in the conventional case.
＜実施例＞ 以下には、図面を参照して、この発明の実施例について
詳しく説明をする。<Example> Hereinafter, an example of the present invention will be described in detail with reference to the drawings.
第１図は、この発明の一実施例にかかる縦引き用手引き
鋸の鋸歯列の拡大部分斜視図である。また、第２図は、
第１図の線II−IIに沿う断面図である。FIG. 1 is an enlarged partial perspective view of a saw tooth row of a vertical pulling hand saw according to an embodiment of the present invention. Also, in FIG.
FIG. 2 is a sectional view taken along the line II-II in FIG. 1.
第１図および第２図において、１は第１縦引き歯であ
り、２は第２縦引き歯であって、これら第１縦引き歯１
および第２縦引き歯２は、のこ身３の腹（下辺部）に列
設されている。1 and 2, 1 is a first vertical pulling tooth, 2 is a second vertical pulling tooth, and these first vertical pulling teeth 1
The second vertical pulling teeth 2 are arranged on the belly (lower side portion) of the saw body 3.
第１縦引き歯１または第２縦引き歯２には、それぞれ、

れ、アサリ振りがされている。The first vertical pulling tooth 1 or the second vertical pulling tooth 2 has,
A lower blade 11 or 21 is formed which is perpendicular to the plane of the saw-drawing direction arrow A1. Further, the first vertical pulling tooth 1 or the second vertical pulling tooth 2 has the tip portion (the lower portion in the figure) sequentially sorted to the left and right when viewed in the tooth arrangement direction, that is, the saw pulling direction A1, and the clam swing Has been done.
この実施例の特徴は、第１縦引き歯１の所定目数ごと、
たとえば２目ごとに第２縦引き歯２が配列されているこ

き歯（従来の縦引き歯と等しい構造）と異なる次のよう
な構造にされていることである。The feature of this embodiment is that every predetermined number of the first vertical pulling teeth 1,
For example, the second vertical pulling teeth 2 are arranged every two stitches. And the structure of the 2nd vertical pulling tooth 2 is made into the following structures different from the 1st vertical pulling tooth (structure same as the conventional vertical pulling tooth).
すなわち、第２縦引き歯２の先端部には、その側面側に
上目22が形成されている。上目22は、第２縦引き歯２の

されている。次に述べるように、この天23は、鋸断作用
の向上に威力を発揮する。That is, the upper eye 22 is formed on the side surface side of the tip portion of the second vertical pulling tooth 2. The upper eye 22 is formed on the side surface of the second vertical pulling tooth 2 on the set side, and a sharp pointed top 23 is formed by the inner edge of the lower blade 21 and the tip of the upper eye 22. . As described below, the ceiling 23 is effective in improving the sawing action.
すなわち、第３図に示すように、切削作業時において、
第１縦引き歯１は主として下刃11の下端辺によって木材
４の切削を行うが、第２縦引き歯２は、主として鋭利な
天23によって木材４の切削を行う。つまり、第２縦引き
歯２の天23によって木材４の切条溝41の底が切削され
る。天23が鋭利であることから、切削は容易であり、の
こ引き作業が軽く行え、かつ、鋸の切れ味が良くなる。That is, as shown in FIG. 3, during cutting work,
The first vertical pulling tooth 1 mainly cuts the wood 4 by the lower end side of the lower blade 11, while the second vertical pulling tooth 2 mainly cuts the wood 4 by the sharp top 23. That is, the bottom of the cut groove 41 of the wood 4 is cut by the top 23 of the second vertical pulling tooth 2. Since the top 23 is sharp, the cutting is easy, the sawing work is light, and the sharpness of the saw is good.
上述の実施例においては、第２縦引き歯２は、第１縦引
き歯１の所定目数ごと、たとえば２目ごとに挿入配列さ
れているものを取上げたが、これに代え、第１縦引き歯
１と第２縦引き歯２とは、それぞれ、所定数の目数、た
とえば２目を単位として、交互に配列されていてもよ
い。In the above-described embodiment, the second vertical pulling teeth 2 are taken up by inserting the first vertical pulling teeth 1 every predetermined number of stitches, for example, every two stitches, but instead of this, the first vertical pulling teeth 2 are used. The pulling teeth 1 and the second vertical pulling teeth 2 may be alternately arranged with a predetermined number of stitches, for example, two stitches as a unit.
また、上述の所定目数は、２目に限られるわけではな
く、３目以上の任意の目数とすればよいことはもちろん
である。Further, the above-mentioned predetermined number of stitches is not limited to two, and it goes without saying that it may be any number of stitches of three or more.
なお、アサリ振りの振り具合は図示は一例であり、もっ
と大きく振られていても、あるいは小さく振られていて
もよい。It should be noted that the state of swinging the clams is an example shown in the figure, and may be swung further or slightly.
第４図は、第２縦引き歯２の変形例を示す図である。FIG. 4 is a view showing a modified example of the second vertical pulling teeth 2.
第４図に示すように、上目22と下刃21とによって形成さ
れる天23が、尖頭形状でなく、下刃21の下端辺の一部が
残るように、上目22を形成してもよい。この場合におい
ても、第２縦引き歯２の下端辺（天）は、第１縦引き歯
１の先端辺12と比べて相対的に短く、鋭利であるから、
鋸断性能の向上を図れる。As shown in FIG. 4, the upper eye 22 is formed so that the top 23 formed by the upper eye 22 and the lower blade 21 does not have a pointed shape but a part of the lower end side of the lower blade 21 remains. May be. Also in this case, since the lower end side (top) of the second vertical pulling tooth 2 is relatively shorter and sharper than the tip side 12 of the first vertical pulling tooth 1,
The cutting performance can be improved.
