ところで、上記した梳鋏を用いて髪の毛を梳いている時、その作業性がもう一つであると感じられている。すなわち、梳鋏で髪の毛をカットし、そして梳鋏を頭から離して一本一本の櫛状刃25の間に挟まれた髪の毛から抜き取ろうとした場合において、櫛状刃25から毛がスムーズに離れ難く、そこに多少の引抜力を加えなければならなかったのである。このことは、美容師・理容師側にすれば力を要することであり、それだけ作業性が悪いことを意味する。かつ、カットを受けている側の者にとっては、髪の毛が引き抜かれるような感覚を覚えることになり、不快感を感じる。   By the way, when the hair is combed using the above-described scissors, it is felt that the workability is another. That is, when the hair is cut with a scissors, and the scissors are separated from the hairs between the comb-like blades 25 apart from the head, the hairs from the comb-like blades 25 are smooth. It was difficult to leave, and some pulling force had to be applied there. This means that it is necessary for the hairdresser / barber side, and it means that workability is worse. In addition, the person on the side receiving the cut feels the feeling that the hair is pulled out, and feels uncomfortable.

上記問題点についての考察を鋭意押し進めている中で、その原因は、一つ一つの櫛状刃25の断面が角状であることに気付くに至った。すなわち、櫛状刃25の断面が角状であるが為に、髪の毛が櫛状刃25の角部に引っ掛かり、鋏を頭から遠ざけようとした時に、どうしても髪の毛を引っ張り抜くようになっていたのである。   While eagerly pursuing consideration of the above problems, the cause of the problem has come to be noticed that each of the comb-shaped blades 25 has a square cross section. That is, since the cross-section of the comb-shaped blade 25 is square, the hair is caught by the corner of the comb-shaped blade 25 and the hair is inevitably pulled when trying to keep the eyelid away from the head. is there.

従って、櫛状刃25を丸状にすれば良いことが判った。つまり、櫛状刃25の角を無くせば良いことに気付いたのである。   Accordingly, it has been found that the comb blade 25 may be rounded. That is, it has been found that it is sufficient to eliminate the corners of the comb blade 25.

しかしながら、角を取る加工は不可能でないものの、一本一本の櫛状刃の全てにおいて角を取る加工を施すのは極めて大変であり、コストが極めて高く付く。   However, although it is not impossible to process corners, it is extremely difficult to perform corner processing on all of the individual comb-like blades, and the cost is extremely high.

よって、本発明が解決しようとする課題は、カットに際しての作業性が良好で、かつ、カットを受けている者にとっては不快感を感じることが少なく、更には製造コストが高く付かない梳鋏を提供することである。   Therefore, the problem to be solved by the present invention is that the workability at the time of cutting is good, the person who is receiving the cut feels less uncomfortable, and furthermore, the manufacturing cost is not high. Is to provide.

上記の鋏は、特に、鋏が完全に閉じられて第1の鋏半体の刃部と第2の鋏半体の櫛状刃部とが完全に重なり合った状態においては、前記第1の鋏半体の刃部と前記第2の鋏半体の櫛状刃部とは互いの刃部の先端部同士のみが重なり合うよう構成されたものである。或いは、鋏が完全に閉じられて前記第1の鋏半体の刃部と前記第2の鋏半体の櫛状刃部とが完全に重なり合った状態においては、前記櫛状刃部の該重合部分における長さが最長でも3mm(望ましくは0.1〜2mm)であるよう構成されたものである。若しくは、第1の鋏半体と刃の部分が櫛状に構成された第2の鋏半体とが枢支されてなり、前記枢支点を中心として回動させられて閉じられた場合には前記第2の鋏半体の櫛状刃部の先端が前記第1の鋏半体に重なり合うよう構成されてなる鋏において、前記第2の鋏半体の櫛状刃部の先端が、前記鋏の枢支点を通る該鋏の長手方向に沿った方向の仮想中心線を越えた1.5mm以内の領域(望ましくは略仮想中心線上)にあるよう構成されたものである。   The above-mentioned scissors, particularly when the scissors are completely closed and the first scissors half blade part and the second scissors half comb blade part completely overlap, The blade portion of the half body and the comb blade portion of the second saddle half body are configured such that only the tip portions of the blade portions overlap each other. Alternatively, when the scissors are completely closed and the blade portions of the first scissors half and the comb blades of the second scissors half are completely overlapped, the superposition of the comb blades The length of the part is 3 mm (preferably 0.1 to 2 mm) at the longest. Alternatively, when the first saddle half and the second saddle half with the blade portion configured in a comb shape are pivoted and rotated around the pivot point and closed In the scissors constructed such that the tips of the comb blades of the second kite half overlap the first kites half, the tips of the comb blades of the second kite half are the scissors It is configured to be in a region (preferably substantially on the virtual center line) within 1.5 mm beyond the virtual center line in the direction along the longitudinal direction of the rod passing through the pivot point.

又、第2の鋏半体の櫛状刃部の先端が、鋏の長手方向における刃の長さの略半分の位置において最も突出した略円弧状の仮想線上にあるよう構成されたものである。   Further, the tip of the comb blade portion of the second rod half is configured to lie on a substantially arcuate imaginary line that protrudes most at a position approximately half the blade length in the longitudinal direction of the rod. .

本発明では、櫛状刃を、例えば断面略D形状のものとしたから、髪の毛を櫛状刃間から抜き取り易い。すなわち、髪の毛が櫛状刃に引っ掛かり難く、抵抗なくスムーズに抜き取れる。従って、美容師・理容師側からみると、小さな力でカット作業をスムーズに行え、作業性良くリズミカルに行える。かつ、カットを受けている側の者にとっては、髪の毛が引き抜かれるような感覚がなくなる。   In the present invention, since the comb-shaped blade has, for example, a substantially D-shaped cross section, the hair can be easily extracted from between the comb-shaped blades. That is, it is difficult for the hair to be caught on the comb-shaped blade, and the hair can be smoothly extracted without resistance. Therefore, from the viewpoint of the hairdresser / barber, the cutting work can be performed smoothly with a small force and can be performed rhythmically with good workability. Moreover, the person who is receiving the cut loses the feeling that the hair is pulled out.

尚、断面略D形状の部分は櫛状刃の先端部のみでも良い。すなわち、櫛状刃を構成する為の軸の長手方向の全長に亘って断面が略D形状にされていても良いが、先端部のみでも良い。つまり、対向する第1の鋏半体と重なり合う箇所のみが断面が略D形状にされていても良い。すなわち、このように一部分のみとした場合には、それだけ加工が簡単であるからによる。   In addition, only the front-end | tip part of a comb-shaped blade may be sufficient as the part of cross-sectional substantially D shape. That is, the cross section may be substantially D-shaped over the entire length in the longitudinal direction of the shaft for constituting the comb-shaped blade, but only the tip portion may be used. That is, only the part which overlaps with the opposing first saddle half may have a substantially D-shaped cross section. That is, when only a part is formed in this way, the processing is simple.

そして、上記特長を奏する鋏が簡単に得られる。すなわち、櫛状刃における角を取るのは、櫛状刃植設前の段階において出来、つまり櫛状刃とした後で角取り加工しなくて済むから、特に、隣接して軸が設けられた状態での角取り加工で無く、隣に邪魔物が無いから、簡単である。従って、それだけ低コストで鋏が得られる。   A bag having the above features can be easily obtained. That is, the corners of the comb-shaped blades can be taken at the stage before the comb-shaped blades are planted, that is, there is no need to chamfer after making the comb-shaped blades. It is easy because it is not chamfered in the state and there is no obstacle next to it. Therefore, soot can be obtained at a lower cost.

本発明にあっては、櫛状刃(軸)の長さが比較的短いことから、軸を植設して櫛状刃を構成するに際して大きな問題が起きない。すなわち、櫛状刃(軸)の長さが長いと、櫛状刃のブレの心配がそれだけ大きくなるものの、櫛状刃(軸)の長さが短い場合には、櫛状刃のブレを心配しなくても済む。つまり、前記第1の鋏半体の刃部と前記第2の鋏半体の櫛状刃部とは互いの刃部の先端部同士のみが重なり合うよう構成された場合には、櫛状刃(軸)の長さは短いことから、櫛状刃のブレの恐れが無く、高品質な鋏が低廉なコストで得られる。   In the present invention, since the length of the comb-shaped blade (shaft) is relatively short, no major problem occurs when the shaft is implanted to configure the comb-shaped blade. In other words, if the length of the comb blade (shaft) is long, the worries of the comb blade are increased, but if the length of the comb blade (shaft) is short, worries of the comb blade are worried. You don't have to. That is, when the first blade half blade and the second blade half comb blade are configured such that only the tips of the blade portions overlap each other, the comb blade ( Since the length of the shaft) is short, there is no risk of the comb-shaped blade being shaken, and a high-quality kite can be obtained at a low cost.

図1(a),(b),(c),(d),(e)は本発明になる鋏の一実施形態を示すもので、図1(a)は鋏の要部の正面図、図1(b)は第1の鋏半体の要部の正面図(図1(a)とは反対側から見た図)、図1(c)は櫛状刃を有する第2の鋏半体の要部の背面図、図1(d)は第2の鋏半体の要部の側面図(櫛状刃の先端側から見た図)、図1(e)は棒状の櫛状刃の要部の斜視図である。   1 (a), (b), (c), (d) and (e) show an embodiment of a bag according to the present invention, and FIG. 1 (a) is a front view of the main part of the bag. FIG. 1 (b) is a front view of a main part of the first saddle half (viewed from the side opposite to FIG. 1 (a)), and FIG. 1 (c) is a second half with a comb-like blade. FIG. 1 (d) is a side view of the main part of the second saddle half (viewed from the tip side of the comb blade), and FIG. 1 (e) is a rod-like comb blade. It is a perspective view of the principal part.

各図中、Aは、本実施形態になる梳鋏である。   In each figure, A is a bag which becomes this embodiment.

梳鋏Aは、第1の鋏半体(非櫛状刃)1と第2の鋏半体(櫛状刃)2とが螺子3によって螺着された構造のものである。   The scissors A have a structure in which a first scissors half (non-comb blade) 1 and a second scissors half (comb blade) 2 are screwed together by screws 3.

第1の鋏半体(非櫛状刃)1は、上部(刃部)4と中部(螺着部)5と下部6(指通部:図示せず)とからなる。そして、図1(b)からも判る通り、刃部4の刃先7の全体形状がその真ん中辺りで多少凸状に膨出した円弧状に形成されている。すなわち、図1(b)にも示される通り、本実施形態における第1の鋏半体(非櫛状刃)1は、鋏Aの長手方向(図1中、上下方向)であって、かつ、螺子3が挿通される螺子孔8を通る中心線を多少(例えば、0.1〜2mm程度。本実施形態では、特に、1〜1.5mm程度。)越えた(図1(b)で説明すると、中心線よりも右側に多少越えた)位置に、円弧状の刃先7があるように構成されている。   The first saddle half (non-comb blade) 1 includes an upper portion (blade portion) 4, a middle portion (screwed portion) 5, and a lower portion 6 (finger passage portion: not shown). As can be seen from FIG. 1 (b), the entire shape of the cutting edge 7 of the blade portion 4 is formed in an arc shape that bulges slightly in the middle. That is, as shown in FIG. 1 (b), the first scissors half body (non-comb blade) 1 in this embodiment is in the longitudinal direction of the scissors A (vertical direction in FIG. 1), and The center line passing through the screw hole 8 through which the screw 3 is inserted slightly exceeds (for example, about 0.1 to 2 mm. In this embodiment, particularly about 1 to 1.5 mm) (in FIG. 1B). If it demonstrates, it will be comprised so that the circular-arc-shaped blade edge 7 may exist in the position (slightly beyond the center line).

第1の鋏半体(非櫛状刃)1と対になる第2の鋏半体(櫛状刃)2は、上部(櫛状刃部)9と中部(螺着部)10と下部11(指通部:図示せず)とからなる。そして、図1(c)からも判る通り、櫛状刃部9の刃先12の形状が、その真ん中辺りで多少凸状に膨出した円弧状に形成されている。又、櫛状刃部9であることから、勿論、櫛状にも形成されている。   The second saddle half (comb blade) 2 paired with the first saddle half (non-comb blade) 1 includes an upper part (comb blade part) 9, a middle part (screwed part) 10, and a lower part 11. (Finger passage: not shown). As can be seen from FIG. 1 (c), the shape of the cutting edge 12 of the comb-shaped blade portion 9 is formed in an arc shape that bulges slightly in the middle. Moreover, since it is the comb-shaped blade part 9, of course, it is also formed in a comb shape.

本実施形態にあっては、刃先12の全体形状が円弧状に形成されていると言うだけで無く、一つ一つの櫛状刃9,9,……,9の長さが従来の梳鋏における櫛状刃の長さよりも短い。すなわち、図2との対比からも判る通り、一つ一つの櫛状刃9,9,……,9の長さが、従来の梳鋏の一つ一つの櫛状刃の長さの約2/3〜1/2程度の長さに設計されている。従って、図1(a)に示される如く、鋏Aが完全に閉じられた状態(第1の鋏半体1の刃部4と第2の鋏半体2の櫛状刃部9とが完全に重なり合った状態)において、第1の鋏半体1の刃部4と第2の鋏半体2の櫛状刃部9とは互いの刃部の先端部同士のみが重なり合っているに過ぎないと言える程度に設計されている。更に具体的に説明すると、図1(a)に示される如く、鋏Aが完全に閉じられた状態(第1の鋏半体1の刃部4と第2の鋏半体2の櫛状刃部9とが完全に重なり合った状態)において、櫛状刃部9と刃部4とが重なり合っている部分の長さが3mm以下(本実施形態の場合では、特に、1〜2mm)であるように櫛状刃9,9,……,9の長さが設計されている。言い換えると、一つ一つの櫛状刃9,9,……,9の先端が、螺子孔8,13を通る鋏Aの長手方向に沿った方向の仮想中心線を越えた1.5mm以内の領域(本実施形態の場合では、ほぼ仮想中心線上)にあるよう櫛状刃9,9,……,9の長さが設計されている。 In the present embodiment, not only say overall shape of the cutting edge 12 is formed in an arc shape, each one of comb-shaped blades 9 1, 9 2, ..., 9 the length of n is conventional It is shorter than the length of the comb-shaped blade in the cocoon. That is, as can be seen from the comparison with FIG. 2, the length of each comb blade 9 1 , 9 2 ,..., 9 n is the length of each comb blade of the conventional scissors. Is designed to have a length of about 2/3 to 1/2. Accordingly, as shown in FIG. 1A, the heel A is completely closed (the blade portion 4 of the first heel half 1 and the comb-like blade portion 9 of the second heel half 2 are completely closed). In the state where the blades 4 of the first rod half 1 and the comb-like blade 9 of the second rod half 2 are overlapped, only the tips of the blades overlap each other. It is designed to the extent that it can be said. More specifically, as shown in FIG. 1A, the heel A is completely closed (the blade portion 4 of the first heel half 1 and the comb blade of the second heel half 2). In the state where the portion 9 is completely overlapped), the length of the portion where the comb-like blade portion 9 and the blade portion 4 overlap is 3 mm or less (in the case of this embodiment, in particular, 1 to 2 mm). The lengths of the comb blades 9 1 , 9 2 ,..., 9 n are designed. In other words, the tips of the individual comb-shaped blades 9 1 , 9 2 ,..., 9 n have passed the virtual center line in the direction along the longitudinal direction of the flange A passing through the screw holes 8 and 13. The lengths of the comb-shaped blades 9 1 , 9 2 ,..., 9 n are designed so as to be in an area within 5 mm (in the case of the present embodiment, substantially on the virtual center line).

尚、梳鋏であることから、図1(a)に示される如く、鋏Aが完全に閉じられた状態において、櫛状刃間には長手状の空隙14が形成されているものである。尚、この空隙14に髪の毛が入る。   Since it is a scissors, as shown in FIG. 1 (a), when the scissors A are completely closed, a long gap 14 is formed between the comb-shaped blades. In addition, hair enters this gap 14.

上記のように構成させた梳鋏Aは、その櫛状刃9,9,……,9の長さが従来の梳鋏の櫛状刃の長さよりも短い。従って、櫛状刃に力が作用しても、ブレが起き難い。例えば、櫛状刃の長さが長いと、櫛状刃に力が作用した場合、例えば第1の鋏半体1側に押圧するような力が作用した場合には、櫛状刃9,9,……,9の中の何れかの櫛状刃が第1の鋏半体1の刃部4側に押され、櫛状刃部9と刃部4とは必要以上に圧接するようになり、鋏の動作性が非常に低下する。逆に、第1の鋏半体1側から離間させる方向の力が作用した場合には、櫛状刃9,9,……,9の中の何れかの櫛状刃が第1の鋏半体1の刃部4側から離れるようになり、櫛状刃部9と刃部4とは必要以上に離間するようになり、鋏の切れ味が非常に低下する。すなわち、何れにしても、櫛状刃9,9,……,9がブレ易いことは決して好ましいことでは無い。そして、このブレ易さは、櫛状刃では無い刃部4には起き難いものであるのに対して、櫛状刃部9は櫛状刃であるが故に起き易いものである。しかしながら、ブレが起き易いと雖も、その長さが短い場合には、ブレは起き難い。つまり、本実施形態の梳鋏は、櫛状刃にブレが起き難く、従って梳鋏の動作性が良好であると共に切れ味にも優れたものである。 The length of the comb-shaped blades 9 1 , 9 2 ,..., 9 n of the kite A configured as described above is shorter than the length of the conventional comb-shaped blade. Therefore, even if a force acts on the comb-shaped blade, blurring hardly occurs. For example, when the length of the comb-shaped blade is long, when a force acts on the comb-shaped blade, for example, when a force that presses against the first saddle half 1 side acts, the comb-shaped blade 9 1 , Any comb blade in 9 2 ,..., 9 n is pushed toward the blade portion 4 side of the first saddle half 1 and the comb blade portion 9 and the blade portion 4 are in pressure contact more than necessary. As a result, the operability of the bag is greatly reduced. Conversely, when the force to separate from the first鋏半body 1 side is applied, the comb-shaped blades 9 1, 9 2, ..., is one of the comb-shaped blade in the 9 n first As a result, the comb-shaped blade portion 9 and the blade portion 4 are separated from each other more than necessary, and the sharpness of the reed is greatly reduced. That is, in any event, the comb-shaped blades 9 1, 9 2, ..., is not in any way desirable is 9 n be easily shake. This ease of shaking is unlikely to occur in the blade portion 4 that is not a comb-shaped blade, whereas the comb-shaped blade portion 9 is likely to occur because it is a comb-shaped blade. However, if the blur is likely to occur, the blur is less likely to occur if the length is short. That is, the scissors according to the present embodiment are less likely to be shaken in the comb-like blades, and therefore the operability of the scissors is good and the sharpness is excellent.

又、櫛状刃の長さが短くて済むことは、それだけ櫛状刃を形成する作業性が良いことを意味する。かつ、材料も少なくて済むので、省資源の観点からも好ましい。   In addition, the fact that the length of the comb-shaped blade is short means that the workability for forming the comb-shaped blade is good. In addition, since less material is required, it is preferable from the viewpoint of resource saving.

又、櫛状刃9の長さ、櫛状刃9の長さ、……、櫛状刃9の長さ、即ち、各櫛状刃の長さに変動が少なく、従来の梳鋏の如く、(一番長い櫛状刃の長さ)/(一番短い櫛状刃の長さ)が2倍以上にもなると言ったことが無く、1.1<(一番長い櫛状刃の長さ)/(一番短い櫛状刃の長さ)<1.5と言った如く、各櫛状刃の長さに大きな相違が無く、ほぼ一定の長さであることから、切り始めと切り終わりとの間における鋏の開閉角度は小さく、従ってカットに際しての動作性も良い。 Further, the comb-shaped blades 9 1 length, the comb-shaped blades 9 2 lengths, ..., comb blade 9 n length, i.e., less variation in the length of the comb-shaped blades, conventional Kezu鋏As described above, (the length of the longest comb-shaped blade) / (the length of the shortest comb-shaped blade) has never been more than twice, 1.1 <(the longest comb-shaped blade) Length) / (shortest comb blade length) <1.5, there is no significant difference in the length of each comb blade, and the length is almost constant. The opening / closing angle of the heel between the cutting end and the cutting end is small, so that the operability in cutting is also good.

そして、上記の梳鋏(第2の鋏半体(櫛状刃)2)は、特に、次のような特徴も持っている。   The above-described kite (second kite half (comb blade) 2) also has the following characteristics.

すなわち、第2の鋏半体(櫛状刃)2は、第2の鋏半体(櫛状刃)2の上部(櫛状刃部)9が、基部(一つ一つの棒状の櫛状刃9,9,……,9が植設される部分)9と、櫛状刃9,9,……,9とから構成されている点にも特徴がある。すなわち、棒状の櫛状刃9,9,……,9の下端部(基端部)が基部9に形成された各々の断面が円形状(又は、180°を越えた角度の円弧状)の穴に挿入・植設されたものである。かつ、櫛状刃9,9,……,9は、円柱状の軸(少なくとも、軸の先端側)が加工されて断面が略D形状のものとされると共に、先端側に刃が形成されたものである。つまり、図1(e)に示される通り、基部9の第k番目の穴に挿入・植設された丸棒9kの先端部9sが、第1の鋏半体1と重なり合った場合に第1の鋏半体1の面に摺接し得るようにする為、第1の鋏半体1対向面が断面略D形状面(平坦面)9Dに加工されている。かつ、丸棒9kの先端部9sが刃となるように加工されている。 That is, the second saddle half (comb blade) 2 has an upper portion (comb blade portion) 9 of the second saddle half (comb blade) 2 as a base (each bar-like comb blade). 9 1, 9 2, ..., and 9 parts n is implanted) 9 0, comb-shaped blades 9 1, 9 2, ..., is characterized in that it is composed of a 9 n. That is, comb-like blades 9 1 rod-shaped, 9 2, ..., 9 lower end portion of the n (base end portion) of the base portion 9 0 which is formed on each of the circular cross-section shape (or, the angle of which exceeds 180 ° It is inserted and planted in an arc-shaped hole. In addition, the comb-shaped blades 9 1 , 9 2 ,..., 9 n have a cylindrical shaft (at least the tip side of the shaft) processed to have a substantially D-shaped cross section, and a blade on the tip side. Is formed. That is, as shown in FIG. 1 (e), when the distal end portion 9 s of the k-th inserted and implanted into the hole of the the round bar 9 k of the base 9 0, overlapping first and鋏半body 1 In order to be able to come into sliding contact with the surface of the first collar half 1, the surface facing the first collar half 1 is processed into a substantially D-shaped surface (flat surface) 9 D in cross section. And round bar 9 k of the front end portion 9 s are processed so that the blade.

基部9側に近い部分は断面D形状では無く、断面が略円形であっても良い。すなわち、図1(a)のような鋏が閉じられた状態において、第1の鋏半体(非櫛状刃)1に摺接する部分のみが断面D形状になっていれば十分である。尚、棒状(丸棒状)の櫛状刃9,9,……,9は、差し込まれる穴が円弧状(端部が開口状)の場合には、棒の端が図1(d)に示される通り、食み出している。従って、棒の上端を断面D形状に成形すれば、櫛状刃9,9,……,9の刃と第1の鋏半体(非櫛状刃)1の刃とが摺接し得る。これに対して、棒状(丸棒状)の櫛状刃9,9,……,9の差し込まれる穴が円形の場合には、この差込部の径が刃の形成される部分の径よりも小さな、即ち、大径部と小径部を有する凸状の棒を用いて櫛状刃9,9,……,9を構成する必要が有る。つまり、このようにすることによって、上記の如きの食み出し部が得られ、断面D形状部を形成できるからである。 Part close to the base 9 0 side is not a cross-section D-shaped cross section may be substantially circular. That is, it is sufficient that only the portion that is in sliding contact with the first half halves (non-comb-like blades) 1 has a D-shaped cross section in a state where the heel is closed as shown in FIG. It should be noted that the rod-shaped (round bar-shaped) comb-shaped blades 9 1 , 9 2 ,..., 9 n have an arc-shaped hole (opened at the end) and the end of the rod is shown in FIG. ) As you can see, it is sticking out. Therefore, if the upper end of the bar is formed into a D-shaped cross section, the blades of the comb blades 9 1 , 9 2 ,..., 9 n and the blades of the first saddle half (non-comb blade) 1 are in sliding contact. obtain. On the other hand, when the hole into which the bar-like (round bar-like) comb-like blades 9 1 , 9 2 ,..., 9 n are inserted is circular, the diameter of the insertion portion is the diameter of the portion where the blade is formed. It is necessary to configure the comb blades 9 1 , 9 2 ,..., 9 n using convex rods that are smaller than the diameter, that is, having a large diameter portion and a small diameter portion. That is, by doing in this way, the above-mentioned protrusion part can be obtained and the cross-section D-shaped part can be formed.

上記特徴の第2の鋏半体(櫛状刃)2は次のようにして得られる。
先ず、櫛状刃9,9,……,9は円柱状軸が植設されて構成されるのであるから、櫛状刃9,9,……,9となる円柱状軸が植設できるものとなる第2の鋏半体(櫛状刃)2の基体を製造する。
The second scissors half body (comb blade) 2 having the above characteristics is obtained as follows.
First, the comb-shaped blades 9 1, 9 2, ..., 9 since n is the cylindrical shaft is configured is implanted, comb-shaped blades 9 1, 9 2, ..., cylindrical as a 9 n The base body of the second halves (comb blades) 2 with which the shaft can be implanted is manufactured.

この基体は、従来からの梳鋏において櫛状刃を除去した構造と同様な構造を基本的に持つものであるが、櫛状刃9,9,……,9が構成される位置に対応して開口部を有する円弧状の穴が形成されたものである。 The substrate is the same structure as the removal of the comb-shaped blade in Kezu鋏from conventional one in which essentially have a comb-shaped blade 9 1, 9 2, ......, 9 n constitute position An arc-shaped hole having an opening corresponding to is formed.

すなわち、軸を植設し、次いで該軸を加工して刃とし、以って第2の鋏半体(櫛状刃)2とするのであるが、軸を植設する前段階の状態の基体を製造する。   That is, a shaft is implanted, and then the shaft is machined to form a blade, thereby forming a second saddle half (comb blade) 2, but the substrate in a state before the shaft is implanted Manufacturing.

又、上記基体の基部9に形成された断面が円弧状の穴の径と同径の外径を持つ所定長さの断面が円形の軸を製造する。 Also, the cross-section of a predetermined length that the base 9 0 which is formed in the cross-section of the substrate having an outer diameter of the same diameter as the diameter of the arc-shaped holes to produce a circular shaft.

次に、上記軸を基部9の上面に穿たれた穴に差し込み、軸を植設する(図1(d)参照)。 Then, insertion into a hole bored the shaft on the upper surface of the base portion 9 0, implanting the axis (see FIG. 1 (d)).

この後、図1(a),(c),(d),(e)に示される如く、軸の先端側9sに対して切削・研磨加工を施し、断面D形状9Dにする。すなわち、該軸の丸味が無い平坦面(前記D形状における平面部)9D側が第1の鋏半体(非櫛状刃)1の面に対向・摺接するよう加工される。 Thereafter, as shown in FIG. 1 (a), (c) , (d), (e), subjected to cutting and polishing to the distal end side 9 s axes, to a cross-sectional D shape 9 D. That is, the flat surface (the flat surface portion in the D shape) 9 D side without the roundness of the shaft is processed so as to face and slide into contact with the surface of the first saddle half (non-comb blade) 1.

次いで、上記軸の先端部(断面D形状部)先端9sを切削・研磨加工し、先端部に刃を形成する。 Next, the tip 9 s of the shaft (D-shaped section) is cut and polished to form a blade at the tip.

このようにして第2の鋏半体(櫛状刃)2が得られるので、この第2の鋏半体(櫛状刃)2と通常の工程を経て得られた第1の鋏半体(非櫛状刃)1とを組み合わせ、螺子3によって螺着することで本発明の梳鋏が得られる。   In this way, since the second saddle half (comb blade) 2 is obtained, the second saddle half (comb blade) 2 and the first saddle half obtained through the normal process ( By combining with the non-comb blade 1 and screwing with the screw 3, the scissors of the present invention can be obtained.

尚、上記実施形態にあっては、上記軸の先端部9sが断面D形状に形成された場合であるが、この平坦面に対向してもう一つの面が存在するような形態であっても良い。すなわち、上記軸の先端部9sが溝状に形成され、この溝内に第1の鋏半体(非櫛状刃)1が嵌り込むようになっていても良い。すなわち、このような場合でも、軸の先端部9sが断面D形状部を有するものである。 In the above-described embodiment, the tip portion 9 s of the shaft is formed in a D-shaped cross section, and there is another mode in which another surface exists opposite to the flat surface. Also good. That is, the tip end 9 s of the shaft may be formed in a groove shape, and the first scissors half body (non-comb blade) 1 may be fitted into the groove. That is, even in such a case, the tip portion 9 s of the shaft has a D-shaped section.
