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.
従来のカッターナイフの切先は１個しかなかった。Conventional cutter knives had only one cutting edge.
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
。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.
それにしても１枚の刃体で使える切先は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。Even so, only one cutting edge can be used with one blade, and when used for scribing relatively hard objects such as plastic plates, it has the disadvantage that it is not sharp enough and loses its sharpness in a short period of time. Ta.
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。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.
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。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.
次に本発明の構成を図面に示す実施例に従って説明する
。Next, the configuration of the present invention will be explained according to embodiments shown in the drawings.
カッターナイフ刃は鋸歯状の切先１゜２．３を３個有し
ており、カッターナイフの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をカッターナイフのホルダー
（図示せず）の方から見て、刃体４の縦の中心線５の右
側に偏しており、第２切先２は第１切先１とは逆に前記
中心線５の左側に偏しており、第３切先３は前記中心線
５上に位置している。The cutter knife blade has three serrated cutting edges 1° 2.3, and the first cutting edge 1 in the direction of movement of the blade body 4 when using the cutter knife holds the blade body 4 in the cutter knife holder ( (not shown), the second cutting edge 2 is biased to the right of the vertical center line 5 of the blade body 4, and the second cutting edge 2 is biased to the left of the center line 5, contrary to the first cutting edge 1. The third cutting edge 3 is located on the center line 5.
このような構成とするために、切先１，２．３はそれら
の側面を刃体４の縁部を斜面状に切削して刃縁を形成す
ることにより形成されるのであるが、その際に第２図に
示すように第１切先１と第２切先２のそれぞれ左右の切
削面６の幅を互いに異ならせることにより、第１切先１
と第２切先２は前記中心線５を間にはさんで両側に偏在
する。In order to achieve 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 their side surfaces to form a blade edge. 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 as shown in FIG.
and the second cutting edge 2 are unevenly distributed on both sides with the center line 5 in between.
第３切先３を形成する際には、前記切削面６の幅を同一
にすることにより第３切先３は前記中心線５上に位置す
る。When forming the third cutting edge 3, the third cutting edge 3 is located on the center line 5 by making the width of the cutting surface 6 the same.
また、他の方法として、前記中心線５上に一列に並んだ
切先１，２．３のうち第１切先１をホルダーの方から見
て前記中心線５の右側に湾曲させ、第２切先２を前記中
心線５の左側に湾曲させ、第３切先３をそのままとして
おくことによってもできる。In addition, as another method, among the cutting edges 1 and 2.3 lined up in a row on the center line 5, the first cutting edge 1 is curved to the right of the center line 5 when viewed from the holder, and the second This can also be done by curving the tip 2 to the left of the center line 5 and leaving the third tip 3 as it is.
各切先１，２．３の高さは同一でもよいが、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。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の中間山部１０を削り取ることにより、より深い
溝１１を形成する。When using the cutter knife, by pulling the blade 4 toward you, the first cutting edge 1 and the second cutting edge 2 form two grooves 8 and 9 on the surface of the object to be cut 7, and then the third A deeper groove 11 is formed by the cutting edge 3 scraping off the intermediate peak portion 10 of the grooves 8 and 9.
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の中心線５からいずれか一力の側に偏しており、
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１０を
削るだけでよい。As described above, in the present invention, among at least three cutting edges of the blade body 4, the first cutting edge 1 in the direction of movement of the blade body 4 during use is on one side from the center line 5 of the blade body 4. biased toward
The second cutting edge 2 is offset from the center line 5 to the opposite side from the first cutting edge 1, 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 and 9, so the third cutting edge 3 forms the middle peak between the two grooves 8 and 9. Just remove 10.
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。Therefore, when scribing the workpiece 7, compared to using a cutter knife with only one cutting edge or a cutter knife with cutting edges lined up on the same line, the three according to the present invention
Since the amount of work required for each of the cutting edges 1, 2, and 3 is small, there is an effect that marking can be done with less effort.
また深い罫書きを効果的に形成できる。Further, deep markings can be effectively formed.
さらに各切先Ｌ２，３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 L2, 3 is small, there is an effect that the cutting edge 1.2.3 is less damaged and lasts for a long time.
