Description

本発明は、２つの刃体がＸ状に交差して回動可能に結合された理髪用鋏に関する。 The present invention relates to hairdressing scissors in which two blades intersect in an X shape and are rotatably connected.

従来、例えば特許文献１に開示されているように、カット時に髪の毛が刃線に沿って滑るのを防止するため、鋏の刃の部分に切り込み溝をつけた溝付きハサミがあった。特許文献１の図面には、円弧形やＶ字形の切り込み溝が記載されている。 Conventionally, as disclosed in Patent Document 1, for example, there has been a grooved scissors having a notch groove in the blade portion of the scissors in order to prevent the hair from slipping along the blade line at the time of cutting. The drawing of Patent Document 1 describes an arc-shaped or V-shaped notch groove.

理髪用鋏は、カット時に髪の毛を滑りにくくする効果と、指に抵抗感なくスムーズにカットできる切れ味の両方を備えていることが重要である。しかし、滑り止め効果と切れ味は相反する機能であり、特許文献１の溝付きハサミの構造では、滑り止め効果と切れ味をバランスよく向上させることが難しく、さらなる改善が必要である。 It is important that the hairdressing scissors have both the effect of making the hair less slippery when cutting and the sharpness that allows the hair to be cut smoothly without feeling resistance to the fingers. However, the anti-slip effect and the sharpness are contradictory functions, and it is difficult to improve the anti-slip effect and the sharpness in a well-balanced manner with the structure of the grooved scissors of Patent Document 1, and further improvement is required.

本発明は、優れた滑り止め効果と優れた切れ味をバランスよく実現できる理髪用鋏を提供することを目的とする。 An object of the present invention is to provide hairdressing scissors capable of achieving an excellent anti-slip effect and an excellent sharpness in a well-balanced manner.

本発明は、２つの刃体がＸ状に交差して回動可能に結合された理髪用鋏であって、前記２つの刃体の中の少なくとも一方が、刃線に複数の凹溝が鋸歯状に連続形成された溝付き刃体であり、前記凹溝は、前記溝付き刃体の刃線を直角に切り込むように形成された第一の切り込み面と、前記溝付き刃体の刃線を鈍角に切り込むように形成されて前記第一の切り込み面の最深部に達する第二の切り込み面とで構成され、前記第一の切り込み面が刃先側に、前記第二の切り込み面が刃元側に各々配置されている理髪用鋏である。 The present invention is a hairdressing scissors in which two blades intersect in an X shape and are rotatably connected, and at least one of the two blades has a plurality of concave grooves on the blade line. It is a grooved blade that is continuously formed in a shape, and the concave groove has a first cut surface formed so as to cut the blade line of the grooved blade at a right angle, and a blade line of the grooved blade. It is composed of a second cut surface that is formed so as to cut at an blunt angle and reaches the deepest part of the first cut surface, the first cut surface is on the cutting edge side, and the second cut surface is on the cutting edge side. Hairdressing scissors placed on each side.

例えば、前記第一の切り込み面の切り込み深さが０．０８〜０．１２ｍｍの範囲に設定され、前記凹溝の開口幅が０．１５〜０．５５ｍｍの範囲に設定され、凹溝の厚みが０．２〜０．３ｍｍの範囲に設定されている。 For example, the depth of cut of the first cut surface is set in the range of 0.08 to 0.12 mm, the opening width of the groove is set in the range of 0.15 to 0.55 mm, and the thickness of the groove is set. Is set in the range of 0.2 to 0.3 mm.

前記２つの刃体のうちの一方の静刃である刃体に前記凹溝が形成され、他方の動刃である刃体には前記凹溝が形成されていないものである。 The concave groove is formed in one of the two blades, which is a static blade, and the concave groove is not formed in the blade, which is the other moving blade.

本発明の理髪用鋏は、２つの刃体の中の少なくとも一方が、刃線に複数の凹溝が鋸歯状に連続形成された溝付き刃体であり、各凹溝が独特な形状に形成されているので、優れた滑り止め効果と優れた切れ味という相反する機能をバランスよく実現することができる。 The hairdressing scissors of the present invention are grooved blades in which at least one of the two blades has a plurality of concave grooves continuously formed in a sawtooth shape on the blade line, and each concave groove is formed in a unique shape. Therefore, the contradictory functions of excellent anti-slip effect and excellent sharpness can be realized in a well-balanced manner.

また、凹溝の各部の寸法を規定範囲内に設定することによって、特に日本人女性の髪の毛のカットに好適な理髪用鋏を得ることができる。 Further, by setting the dimensions of each part of the concave groove within the specified range, it is possible to obtain hairdressing scissors particularly suitable for cutting the hair of Japanese women.

本発明の一実施形態の理髪用鋏の外観を示す斜視図である。It is a perspective view which shows the appearance of the hairdressing scissors of one Embodiment of this invention. 溝付き刃体の刃線及び凹溝の部分を刃線側から見た拡大図（ａ）、刃線及び凹溝の部分の拡大平面図（ｂ）である。It is an enlarged view (a) which looked at the blade line and the concave groove part of the grooved blade body from the blade line side, and is the enlarged plan view (b) of the blade line and the concave groove part.

以下、本発明の理髪用鋏の一実施形態について、図面に基づいて説明する。この実施形態の理髪用鋏１０は、図１に示すように、刃体１２（静刃）と刃体１４（動刃）とがＸ字状に交差し、軸部材１６を介して互いに回動可能に結合された構造になっている。刃体１２，１４の刃線１２ａ，１４ａは、直線と曲線のどちらでもよく、この実施形態では直線刃に適用した例を示す。刃体１２の刃線１２ａには、刃先１２ｂから刃元１２ｃにかけて、複数の凹溝１８が鋸歯状に連続形成されており、以下、刃体１２を溝付き刃体１２と称する。 Hereinafter, an embodiment of the hairdressing scissors of the present invention will be described with reference to the drawings. In the hairdressing scissors 10 of this embodiment, as shown in FIG. 1, the blade body 12 (static blade) and the blade body 14 (moving blade) intersect in an X shape and rotate with each other via the shaft member 16. It has a structure that is possible to combine. The blade lines 12a and 14a of the blade bodies 12 and 14 may be either straight or curved, and in this embodiment, an example applied to a straight blade is shown. A plurality of concave grooves 18 are continuously formed in the blade line 12a of the blade body 12 from the blade edge 12b to the blade base 12c in a sawtooth shape. Hereinafter, the blade body 12 is referred to as a grooved blade body 12.

図２（ａ）、（ｂ）に示すように、各凹溝１８は、刃先１２ｂ側に配置された第一の切り込み面２０と、刃元１２ｃ側に配置された第二の切り込み面２２とで構成されている。第一の切り込み面２０は、刃線１２ａを直角に切り込むように形成され、第二の切り込み面２２は、刃線１２ａを鈍角に切り込むように形成されて第一の切り込み面１８の最深部に達している。 As shown in FIGS. 2A and 2B, each of the concave grooves 18 includes a first cutting surface 20 arranged on the blade edge 12b side and a second cutting surface 22 arranged on the blade edge 12c side. It is composed of. The first cut surface 20 is formed so as to cut the blade line 12a at a right angle, and the second cut surface 22 is formed so as to cut the blade line 12a at an obtuse angle to the deepest portion of the first cut surface 18. Has reached.

刃線１２ａに対して直角な第一の切り込み面２０は、カット時、髪の毛Ｈａが刃先１２ｂの方に向かって移動するのを防止するストッパの働きをする。一方、刃線１２ｂに対して傾斜している第二の切り込み面２２は、カット時、髪の毛Ｈａを刃先１２ｂの方向に少しだけ滑らせる働きをし、これによって刃線１２ｂ，１４ｂが髪の毛Ｈａに食い込みやすくなり、切れ味が良くなる。そして、これらの動作が良好に行われるように寸法Ａ，Ｂ，Ｃを調節する。 The first cut surface 20 perpendicular to the blade line 12a acts as a stopper that prevents the hair Ha from moving toward the blade edge 12b during cutting. On the other hand, the second cut surface 22 inclined with respect to the blade line 12b functions to slightly slide the hair Ha in the direction of the cutting edge 12b at the time of cutting, whereby the blade lines 12b and 14b become the hair Ha. It becomes easier to bite and the sharpness improves. Then, the dimensions A, B, and C are adjusted so that these operations are performed well.

例えば、第一の切り込み面２０の切り込み深さＡは、浅くし過ぎると滑り止め効果が弱くなり、深くし過ぎると切れ味が悪くなる。また、凹溝１８の開口幅Ｂは、広くし過ぎると滑り止め効果が弱くなり、狭くし過ぎると切れ味が悪くなる。また、凹溝１８の厚みＣは、厚くし過ぎると刃線１２ａの尖鋭さが低下して切れ味が悪くなり、薄くし過ぎると刃線及び凹溝が破損しやすくなる。そして、寸法Ａ，Ｂ，Ｃの最適値は、髪の毛Ｈａの太さによって異なってくる。 For example, if the cutting depth A of the first cutting surface 20 is too shallow, the anti-slip effect will be weakened, and if it is too deep, the sharpness will be poor. Further, if the opening width B of the concave groove 18 is too wide, the anti-slip effect is weakened, and if it is too narrow, the sharpness is deteriorated. Further, if the thickness C of the concave groove 18 is too thick, the sharpness of the blade line 12a is lowered and the sharpness is deteriorated, and if it is too thin, the blade line and the concave groove are easily damaged. The optimum values of the dimensions A, B, and C differ depending on the thickness of the hair Ha.

日本人女性の髪の毛Ｈａの太さは、平均値で０．０８ｍｍと言われている。そこで、発明者が鋭意検討したところ、日本人女性用の理髪用鋏１０は、第一の切り込み面２０の切り込み深さＡを０．０８〜０．１２ｍｍ（より好ましくは０．０９〜０．１１ｍｍ）の範囲とし、凹溝１８の開口幅Ｂを０．１５〜０．５５ｍｍ（より好ましくは０．２５〜０．４５ｍｍ）の範囲とし、凹溝１８の厚みＣを０．２〜０．３ｍｍ（より好ましくは０．２３〜０．２７ｍｍ）の範囲とすることによって、優れた滑り止め効果と優れた切れ味をバランスよく実現できることが分かった。 The average hair thickness of Japanese women is said to be 0.08 mm. Therefore, as a result of diligent studies by the inventor, the hairdressing shears 10 for Japanese women have a cut depth A of the first cut surface 20 of 0.08 to 0.12 mm (more preferably 0.09 to 0. 11 mm), the opening width B of the concave groove 18 is in the range of 0.15 to 0.55 mm (more preferably 0.25 to 0.45 mm), and the thickness C of the concave groove 18 is 0.2 to 0. It was found that an excellent anti-slip effect and an excellent sharpness can be achieved in a well-balanced manner by setting the range to 3 mm (more preferably 0.23 to 0.27 mm).

髪の毛Ｈａの太さは、人種や性別によって異なる（例えば、欧米人女性の髪の毛Ｈａの太さは、平均値で０．０５ｍｍと言われている。）ので、日本人女性以外の髪の毛Ｈａをカットする理髪用鋏１０の寸法Ａ，Ｂ，Ｃは、日本人女性用とは異なる値に設定することが好ましい。 The thickness of hair Ha varies depending on race and gender (for example, the thickness of hair Ha of Western women is said to be 0.05 mm on average), so hair Ha other than Japanese women should be used. It is preferable that the dimensions A, B, and C of the hairdressing shears 10 to be cut are set to values different from those for Japanese women.

動刃である刃体１４は、滑らかな直線状又は曲線状の刃線を有し、主に髪の毛Ｈａの切断機能を有する。 The blade body 14, which is a moving blade, has a smooth straight or curved blade line, and mainly has a function of cutting hair Ha.

以上説明したように、理髪用鋏１０は、一方の刃体１２が、刃線１２ａに複数の凹溝１８が鋸歯状に連続形成された溝付き刃体１２であり、各凹溝１８が独特な形状に形成されているので、刃体１２側で優れた滑り止め効果を発揮し、刃体１４による髪の毛Ｈａの切断時に、髪の毛Ｈａが刃先１２ｂ側に逃げず、優れた切れ味を得ることができる。これにより、髪の毛Ｈａの滑り止めと切れ味と言う相反する機能をバランスよく実現することができる。 As described above, in the hairdressing scissors 10, one blade body 12 is a grooved blade body 12 in which a plurality of concave grooves 18 are continuously formed in a sawtooth shape on the blade line 12a, and each concave groove 18 is unique. Since it is formed in a slender shape, it exhibits an excellent anti-slip effect on the blade 12 side, and when the hair Ha is cut by the blade 14, the hair Ha does not escape to the blade edge 12b side, and excellent sharpness can be obtained. it can. As a result, the contradictory functions of non-slip and sharpness of hair Ha can be realized in a well-balanced manner.

なお、本発明の理髪用鋏は、上記実施形態に限定されるものではない。上述の通り、刃体１２，１４の刃線１２ａ，１４ａは、直線と曲線のどちらでも良いが、本発明の実施結果からは、曲線刃の方が滑らかな切れ味が得られた。従って、曲線刃に応用することにより、より有利な効果が得られる。その他、上記の理髪用鋏１０は、静刃である刃体１２だけが溝付き刃体になっているが、動刃である刃体１４だけを溝付き刃体にしてもよいし、刃体１２と１４の両方を溝付き刃体にしてもよい。その他、軸部材の構造やハンドルの形状等は、自由に変更することができる。 The hairdressing scissors of the present invention are not limited to the above embodiments. As described above, the blade lines 12a and 14a of the blade bodies 12 and 14 may be either straight or curved, but from the results of the present invention, the curved blade has a smoother sharpness. Therefore, a more advantageous effect can be obtained by applying it to a curved blade. In addition, in the above-mentioned hairdressing scissors 10, only the blade 12 which is a static blade is a grooved blade, but only the blade 14 which is a moving blade may be a grooved blade. Both 12 and 14 may be grooved blades. In addition, the structure of the shaft member, the shape of the handle, and the like can be freely changed.
