【従来の技術】[Prior Art]

主として理容店等において、職業的に使用されるこの種の梳鋏は、例えば実開昭６３−２２８７０号公報のように、くし歯形の刃部を形成する各刃の刃先をＶ字形にカットしたＶ型刃のものが一般に使用されている。そして、同じく梳鋏において、くし歯形の刃部を形成する各刃の刃先を平刃型にしたものが使用されるようになってきている。 This kind of carding scissors, which is used professionally mainly in barber shops, has a V-shaped cutting edge of each blade forming a comb tooth-shaped blade, as disclosed in, for example, Japanese Utility Model Publication No. 63-22870. V-shaped blades are commonly used. Also, in the same way as scissors, flat blades are used for the blades of the blades forming the comb-shaped blade.

【考案が解決しようとする課題】[Problems to be solved by the device]

梳鋏において、くし歯形の刃部の刃先をＶ型に形成する理由は、直刃形の切断刃との間で促えた毛髪をできるだけ逃がさずに切ることを目的としている。それ故、促らえられた毛髪のほとんどは切断されてしまい、毛髪を少なく梳く場合には不適当であり、その為に、くし歯形の各刃部を極細に形成することも考えられるが、製作上不可能に近く、また、たとえ製作されたとしても使用する場合に非常に不安定である。その要望にこたえるために、同じ梳鋏において、くし歯形の刃部の刃先を平刃型にしたものが製作され、使用されている。 In the carding scissors, the reason why the blade tip of the comb-teeth-shaped blade is formed in a V-shape is to cut the hair urged between the blade and the straight-blade-shaped cutting blade as much as possible. Therefore, most of the promoted hair will be cut, which is not suitable when combing a small amount of hair, and it is conceivable to form each tooth of the comb tooth shape very fine. However, it is almost impossible to manufacture, and even if it is manufactured, it is extremely unstable. In order to meet the demand, a comb-shaped scissors in which the blade tip of the comb tooth-shaped blade portion is a flat blade type is manufactured and used.

【０００４】しかし乍ら、鋏を閉じる切断行程において、枢支軸に近い手元側では、切断刃と梳刃との交差により、平刃型に形成された刃部の切先線の交差角度が比較的に大となり、交差位置が鋏の先に移るに従って鋭角に減少する。そして切先線の交差角度が大のときは、鋏に挾まれた毛髪の逃げ率が約８０％と多く、鋏の先側では逃げ率が約５０％と少なくなる。However, in the cutting process of closing the scissors, on the hand side close to the pivot shaft, the crossing angle of the cutting edge line of the blade portion formed in the flat blade type is made by the crossing of the cutting blade and the carding blade. It becomes relatively large and decreases sharply as the crossing position moves to the tip of the scissors. When the angle of intersection of the cutting lines is large, the escape rate of the hair caught by the scissors is high at about 80%, and the escape rate is about 50% on the tip side of the scissors.

【０００５】そのために、枢支軸に近い手元側と先側とでは毛髪の切断量にばらつきが生じ、そのことを少しでも無くするために、毛髪に対する鋏の当る角度を変えるとか、浮かすとかの技術的な操作を加える必要があった。それ故、くし歯形の刃部の刃先を平刃型にした梳鋏において、鋏の手元側から先端に至るまでの毛髪の逃げ率の変化をなくし、習熟を要することなく、均一な量に切断できるように改良することが解決すべき課題となっていた。Therefore, the hair cutting amount varies between the proximal side and the distal side, which are close to the pivotal axis, and in order to eliminate such variation, changing the angle at which the scissors hit the hair or floating the hair. It was necessary to add technical operations. Therefore, in carding scissors in which the blade edge of the comb-teeth shape is flat blade type, there is no change in the escape rate of the hair from the side of the scissors to the tip, and cutting to a uniform amount without proficiency. Improving as much as possible was a problem to be solved.

【課題を解決するための手段】[Means for Solving the Problems]

そこで本考案は、直刃形の刃部を設けた一方の刃を切断刃とし、くし歯形の刃部を設けた他方の刃を梳刃とする梳鋏において、くし歯形の刃部を形成する各刃は、平刃型の刃先を有し、この各刃の刃先を結ぶ切先線は、中間部分で外側に凸に湾曲する屈曲線をなすことを特徴とする梳鋏を提供するものである。 In view of this, the present invention forms a comb tooth-shaped blade portion in a carding scissor in which one blade provided with a straight blade-shaped blade portion is a cutting blade and the other blade provided with a comb tooth-shaped blade portion is a carding blade. Each blade has a flat blade type cutting edge, and the cutting line connecting the cutting edges of each blade forms a bending line that is convexly curved outward in the middle portion. is there.

【作用】[Action]

上記のように構成した本考案梳鋏は、くし歯形の刃部を形成する各刃の刃先が平刃型であるから、刃部を直刃形に形成した切断刃との間で毛髪を切断するときは、平刃同士の切断となり、各刃毎に生ずる切断抵抗を滑らかにする。また、くし歯部の各刃の刃先が形成する切先線は、刃部の長さの中間部分で外側に凸に湾曲した屈曲線をなしているので、枢支軸に近い手元側で、切断刃側の切先線との間に形成するＶ形の交差角が、従来の鋏に比べて小さい角度の鋭角となり、切断すべき毛髪を促え易い。また、中間部分を越えた鋏の先側では、鋏が閉じられる直前に当るので、小さな角度の鋭角を形成する。したがって、刃部の全長に亘ってＶ形に形成される上記切先線の交差角が小さく平均化し、それに従って毛髪の逃げ率も均一化するので、手元側から先端え達するまでに切れる毛髪の量が平均化し、比較的に無雑作な使用が可能になる。本考案は以上のようにして、従来の梳鋏の課題を解消したものである。 In the present invention carding scissors configured as described above, since the blade tip of each blade forming the comb tooth-shaped blade portion is a flat blade type, the hair is cut between the blade and the cutting blade formed in the straight blade type. When doing so, the flat blades are cut, and the cutting resistance generated for each blade is smoothed. In addition, the cutting line formed by the cutting edge of each blade of the comb tooth part is a bending line that is convexly bent outward in the middle part of the length of the cutting part. Thus, the V-shaped crossing angle formed between the cutting edge side and the tip line becomes an acute angle smaller than that of conventional scissors, and it is easy to promote the hair to be cut. On the tip side of the scissors beyond the middle portion, a small acute angle is formed because the scissors hit just before the scissors are closed. Therefore, the crossing angle of the above-mentioned cutting lines formed in a V shape over the entire length of the blade portion is small and averaged, and the escape rate of the hair is made uniform accordingly, so that the cutting is performed from the hand side to the tip end. The amount of hair is averaged, which enables relatively crude use. As described above, the present invention solves the problems of the conventional card scissors.

【実施例】【Example】

以下に本考案の実施例を図面について説明する。図において、１は一端に環状の指掛け部２を有し、直刃形の刃部３を具えた切断刃、４は同じく一端に環状と反り爪状の指掛け部５を有し、刃６と欠刃部７を交互に配設して、くし歯形の刃部８を形成した梳刃、９は切断刃１と梳刃４を開閉自在に交差させて枢着する枢支軸である。 Embodiments of the present invention will be described below with reference to the drawings. In the figure, reference numeral 1 denotes a cutting blade having an annular finger hook portion 2 at one end, and a straight blade-shaped blade portion 3, and 4 also has an annular and cambered finger hook portion 5 at one end, and a blade 6 And a cutting edge portion 7 are alternately arranged to form a comb-shaped blade portion 8. A reference numeral 9 is a pivot shaft that pivotally connects the cutting blade 1 and the combing blade 4 so that they can be opened and closed. .

【０００９】くし歯形の刃部８を形成する各刃６は、Ｖ字形のカットのない平刃型の刃先１０を有する。また、枢支軸９に近い手元側から鋏の先端までを形成する上記各刃６の刃先１０を結ぶ切先線Ｌは、直線ではなく、手元側から中間部分までと、中間部分Ｐから鋏の先に達するまでの部分で異なる傾斜を有し、中間部分Ｐで外側に凸に湾曲する屈曲線を形成するように上記各刃６の長さが設定されている。Each of the blades 6 forming the comb-shaped blade portion 8 has a V-shaped flat blade-shaped cutting edge 10 without a cut. Further, the cutting edge line L connecting the cutting edges 10 of the above-mentioned blades 6 forming the side closer to the pivot shaft 9 to the tip of the scissors is not a straight line, but from the proximal side to the intermediate portion and from the intermediate portion P to the scissors. The lengths of the blades 6 are set so that they have different inclinations until reaching the tip of the blade, and form a bent line that is convexly curved outward at the intermediate portion P.

【００１０】くし歯形の刃部８の刃６を、上記のように平刃型の刃先１０に形成し、切先線Ｌを上記のような屈曲線に形成したこの梳鋏は、図２中に実線で示す鋏の閉じはじめの位置で、切断刃１の刃部３と梳刃４の切先線Ｌとが形成する交差角は、上記凸の屈曲線の前半に相当して、従来の鋏の交差角よりも小さな角度の交差角度Ｐ１を形成し、両刃１、４の交差位置が中間部分Ｐを越える位置では、上記凸の屈曲線の後半に相当して、同図中、鎖線で示すように、交差角度Ｐ２を形成する。中間部分Ｐを越えた後の上記交差角度Ｐ２は、鋏が閉じられる直前に当るので、小さな角度の鋭角を形成する。したがって、湾曲する切先線Ｌが形成する交差角度は、刃の全長に亘ってほぼ均一に近く、小さな角度の鋭角となる。The carding scissors in which the blade 6 of the comb-shaped blade portion 8 is formed on the flat blade type cutting edge 10 as described above and the cutting edge line L is formed in the bending line as described above are shown in FIG. At the closing position of the scissors shown by the solid line, the intersection angle formed by the blade portion 3 of the cutting blade 1 and the cutting edge line L of the carding blade 4 corresponds to the first half of the above-mentioned convex bending line. , A crossing angle P1 that is smaller than the crossing angle of the conventional scissors is formed, and at a position where the crossing positions of the two blades 1 and 4 exceed the intermediate portion P, it corresponds to the latter half of the convex bending line, , Form a crossing angle P2, as indicated by the dashed line. The crossing angle P2 after passing over the intermediate portion P hits just before the scissors are closed, thus forming a small acute angle. Therefore, the intersecting angle formed by the curved cutting line L is almost uniform over the entire length of the blade and becomes a small acute angle.

【００１１】図３ａ、ｂは、梳鋏における毛髪の切断状態を説明するもので、同図ａに示すように、Ｖ字形のカットを刃先１１に形成した従来品においては、刃先１１内に促えた毛髪Ｈのほとんどを一挙に切断する。そして、同図ｂに示すように、平刃型の刃先１０を有する本考案の場合は、刃先１０に促える毛髪Ｈの逃げ率が大きいが、前記交差角度が小さい場合に、鋏が閉じる時の力が毛髪Ｈを押す方向よりも切断する方向に大きく働いて、切断率が高くなることを示している。FIGS. 3 a and 3 b are for explaining the cutting state of the hair in the carding scissors. As shown in FIG. 3 a, in the conventional product in which a V-shaped cut is formed on the cutting edge 11, the cutting is promoted within the cutting edge 11. Most of the obtained hair H is cut at once. Then, as shown in FIG. 6B, in the case of the present invention having the flat blade type cutting edge 10, the escape rate of the hair H urged by the cutting edge 10 is large, but the scissors are closed when the crossing angle is small. It is shown that the force of time acts more greatly in the cutting direction than in the pressing direction of the hair H, and the cutting rate increases.

【００１２】即ち、この実施例は、平刃型の刃物同士の切断によって、各刃６毎の毛髪の切断を除除に行なって抵抗を軽減し、鋏の切りはじめに生ずる交差角を小さな角度の鋭角に形成せしめることによって、毛髪の逃げ率を低く抑え、元来、上記交差角が小さくなって毛髪の逃げ率が低くなる中間部分Ｐから先の切断では、通常の梳鋏の場合とほとんど同様の切断を行う。That is, in this embodiment, the cutting of the hair of each blade 6 is eliminated by cutting the flat blade type blades together to reduce the resistance, and the crossing angle at the beginning of cutting the scissors is reduced to a small angle. By forming it at an acute angle, the escape rate of the hair is suppressed to a low level. Originally, when cutting from the middle part P where the crossing angle becomes small and the escape rate of the hair becomes low, it is almost the same as in the case of normal carding scissors. Make the same disconnection.

【考案の効果】[Effect of the device]

以上のように、直刃形の刃部を設けた一方の刃を切断刃とし、くし歯形の刃部を設けた他方の刃を梳刃とする梳鋏において、本考案は、くし歯形の刃部を形成する各刃の刃先を平刃型にして毛髪の切断を平刃型の刃物同士の切断によって行うようにしたので、切断に際して生ずる抵抗を軽減し、切れ味がスムーズとなる。また、くし歯形の刃部の各刃の刃先を結ぶ切先線が、中間部分で外側に凸に湾曲する屈曲線をなすように形成することによって、切断刃と梳刃の刃部の切先線との交差角を鋏の中間部分から手前側では小さな角度の鋭角を形成せしめるようにしたので、切りはじめから中間部分に至るまでの間の毛髪の逃げ率を低く抑えることができ、刃部の長さの全長に亘って毛髪の切断量を平均化し得る。したがって、本考案によれば、特段の調髪技術を要さずに梳鋏を使用することができ、また、疲労も少くないという実用的効果がある。 As described above, in the carding scissors in which one of the blades having the straight blade shape is the cutting blade and the other blade having the comb tooth-shaped blade is the carding blade, the present invention provides the comb-shaped blade. The blade tip of each blade forming the part is a flat blade type to cut the hair by cutting the blades of the flat blade type, so that the resistance generated during cutting is reduced and the sharpness is smooth. In addition, by forming the cutting line connecting the cutting edges of the comb-shaped blades so as to form a curved line that bends outward in the middle, the cutting edges of the cutting blade and the carding blade are cut. Since the angle of intersection with the front line is set to form a small acute angle from the middle part of the scissors to the front side, the escape rate of hair from the beginning of cutting to the middle part can be kept low, The amount of hair cut can be averaged over the entire length of the blade. Therefore, according to the present invention, there is a practical effect that the carding scissors can be used without requiring a special hairdressing technique and the fatigue is small.
