Description
【発明の詳細な説明】 本発明はカッターナイフ刃の改良に係るものである。[Detailed description of the invention] The present invention relates to an improvement of a cutter knife blade.
１−
従来のカッターナイフの切先は１個しかなかった。切先
が摩耗によって鈍くなると予めつけられている平行折線
の箇所で刃体を折って新たな切先として使っていた。そ
れにしても１枚の刃体で使える切先け１個だけであり、
プラスチック板等の比較的硬い物の罫書きに使用すると
十分な切れ味が得られず、また短時間で切れ味が落ちる
という欠点があった。1- Conventional utility knives had only one cutting edge. When the cutting edge became dull due to wear, the blade was broken at the pre-marked parallel fold lines and used as a new cutting edge. Even so, only one cutting edge can be used with one blade,
When used for scribing relatively hard objects such as plastic plates, sufficient sharpness cannot be obtained, and the sharpness deteriorates in a short period of time.
そこで、１枚の刃体に複数の切先を設けて、しかもそれ
らの切先が一列に並んでいるのではなく、偏在している
ことが本発明の特徴である。複数の切先が偏在している
切断具として鋸があるが、鋸の切先は鋸の刃体の縦の中
心線をはさんで交互に切先が偏在しているだけである。Therefore, a feature of the present invention is that a single blade body is provided with a plurality of cutting edges, and the cutting edges are not arranged in a line but are unevenly distributed. A saw is a cutting tool that has a plurality of unevenly distributed cutting edges, but the cutting edges of a saw are simply unevenly distributed alternately across the vertical center line of the saw blade.
これに対して本発明は刃体に設けられた複数の切先を刃
体の中心線上及び中心線の両側に偏在させることにより
プラスチックのような比較的硬い物をも切断し易くしよ
うとするものである。In contrast, the present invention attempts to make it easier to cut relatively hard objects such as plastic by unevenly distributing a plurality of cutting edges provided on the blade on the center line of the blade and on both sides of the center line. It is.

もよいが、この実施例では第３切先３の高さが第１及び
第２の切先１．２よりも高い。Next, the configuration of the present invention will be explained according to embodiments shown in the drawings. The cutter knife blade has three serrated cutting edges 1, 2 and 3, and the first cutting edge 1 in the direction of movement of the blade 4 when using the cutter knife holds the blade 4 in the holder of the cutter knife ( (not shown), the second cutting edge 2 is biased to the right of the vertical center line 6 of the blade 4, and the second cutting edge 2 is biased to the left of the center la5, contrary to the first cutting edge l. The third cutting edge 3 is located on the center line 5. In order to obtain such a configuration, the cutting edges 1, 2, and 3 are formed by cutting the edge of the blade body 4 into a slope shape on the side surfaces thereof to form a blade edge. As shown in FIG. 2, by making the widths of the left and right cutting surfaces 6 of the first cutting edge 1 and the second cutting edge 2 different from each other, the first cutting edge 1 and the second cutting edge 2 are cut at the center. They are unevenly distributed on both sides with line 5 in between. When forming the third cutting edge 3, the third gJ tip 3 is located on the center line 5 by making the width of the cutting surface 6 the same. In addition, as another method, the cutting tips are lined up on the center line 5.
Among L2.3, the first cutting edge 1 is curved to the right of the center line 5 when viewed from the holder, and the second cutting edge 2 is curved to the right of the center line 5 when viewed from the holder.
This can also be done by curving it to the left side and leaving the third tip 3 as it is. The height of each cutting edge 1.2.3 may be the same, but in this embodiment the height of the third cutting edge 3 is higher than the first and second cutting edge 1.2.
カッターナイフの使用時において刃体４を手前に引くこ
とにより、第１切先１と第２切先２が被切断物７の表面
に２条の溝８．９を形成し、続いて第３切先３が前記溝
８．９の中間山ｉ１０を削ヵ取ることにより、より深い
溝１１を形成する。When the cutter knife is used, by pulling the blade 4 toward you, the first cutting edge 1 and the second cutting edge 2 form two grooves 8.9 on the surface of the object 7, and then the third A deeper groove 11 is formed by cutting off the intermediate ridge i10 of the groove 8.9 with the cutting edge 3.
本発明は前述の如く、刃体４の少なくとも３個の切先の
うち、使用時における刃体４の進行方向の第１切先１は
刃体４の縦の中心線５からいずれか一方の側に偏してお
り、第２切先２は前記中心線５から第１切先１とは逆の
側に偏しており、かつ第３切先３は前記中心線５上に位
置しているという構成を有し、刃体４を手前に引くこと
により第１切先１と第２切先２とが２条の溝８．９を形
成するから、第３切先３は２つの溝８．９の中間山部１
０を削るだけでよい。したがって被切断物７の罫書きを
する際に、切先が１個しかないカッターナイフ又は切先
が同一線上に並んだカッターナイフで作業をするのに比
べて、本発明に係る３個の切先１．２．３の各々の作業
量は少なくてすむので、より少ない労力で罫書きをする
ことができるという効、果がある。また深い罫書きを効
果的に形成できる。As described above, in the present invention, among the at least three cutting edges of the blade 4, the first cutting edge 1 in the direction of movement of the blade 4 during use is located from one of the vertical center lines 5 of the blade 4. The second cutting edge 2 is biased toward the opposite side of the first cutting edge 1 from the center line 5, and the third cutting edge 3 is located on the center line 5. By pulling the blade 4 toward you, the first cutting edge 1 and the second cutting edge 2 form two grooves 8.9, so the third cutting edge 3 forms two grooves. 8.9 middle mountain part 1
Just remove the 0. Therefore, when scribing the workpiece 7, compared to using a cutter knife with only one cutting edge or a cutter knife with cutting edges aligned on the same line, it is possible to use three cutting edges according to the present invention. Since the amount of work in each of 1.2.3 above is small, there is an effect that marking can be done with less effort. Further, deep markings can be effectively formed.
さらに各切先１．２．３の作業量が少なくてすむことか
ら、切先１．２．３の損傷が少なく切先１．２．３が長
持ちするという効果もある。Furthermore, since the amount of work required for each cutting edge 1.2.3 is small, there is an effect that the cutting edge 1.2.3 is less likely to be damaged and can last longer.
