Abstract

<P>PROBLEM TO BE SOLVED: To provide a pair of thinning scissors which can prevent the distal end sections of the blades from being broken, and in addition, which is excellent in cutting performance as well. <P>SOLUTION: For this thinning scissors 10, a first scissor element 11 on which a comb blade 12 is formed, and a second scissor element 21 on which a bar blade 22 is formed are integrated by a screw 31. In the thinning scissors 10, a sharp cutting edge 15 is formed on the distal end sections of individual fine blades 13 which constitute the comb blade 12, and at the same time, a slope 24 is installed on the distal end section of the bar blade 22. Then, a cutting edge 25 is formed on the corner section of the slope 24 as well. In addition, on the slope 24, a protruding piece 26 is formed at the contact starting position with individual fine blades 13, and a release surface 27 is formed on the protruding piece 26. Thus, when the comb blade 12 comes into contact with the bar blade 22, the cutting edges 15 of the fine blades 13 do not get over the bar blade 22, and the blades are prevented from being broken. In addition, since there are the cutting edges 15 and 25 on both of the comb blade 12 and the bar blade 22, the cutting sharpness is excellent as well. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

本発明は、頭髪を刈り込む際に使用するスキ鋏に関する。   The present invention relates to a skimmer used when trimming hair.

頭髪を刈り込んで容姿を整える理美容において、頭髪のボリューム感を軽減する手法として、スキ鋏を使用したセニングと呼ばれる技術が知られている。スキ鋏は、鋏を構成する二枚の刃物のうち一方または両方が櫛状になったもので、刃と刃の間に落ち込んだ頭髪は切断されないため、短髪になることを避けながら頭髪量を調整できる。このスキ鋏の基本的な構成を図6に示す。図6(A)は全体を示す斜視図であり、対になる第一鋏体と第二鋏体がネジで回動可能に一体化されており、第一鋏体はネジの左側に櫛刃が形成され、第二鋏体はネジの左側に棒刃が形成されており、また両鋏体とも、右端に指を差し入れるためのハンドルが形成されている。棒刃は、通常の鋏と同様に先端部(鋏を閉じる際に前面となる部分)が、ネジ付近から鋏の先まで直線状に延びているが、櫛刃は、極めて刃渡りの短い微細刃と溝が交互に並び、文字通り櫛状になっている。   In hairdressing and cosmetology that trims the hair and adjusts its appearance, a technique called senning that uses skies is known as a technique for reducing the volume of hair. Ski wrinkles are ones or both of the two blades that make up the wrinkles, and the hair that falls between the blades is not cut, so the amount of hair is reduced while avoiding short hair. Can be adjusted. A basic configuration of this ski is shown in FIG. FIG. 6 (A) is a perspective view showing the whole, and a pair of first and second housings are integrated so as to be rotatable with screws, and the first housing is a comb blade on the left side of the screws. In the second housing, a rod blade is formed on the left side of the screw, and in both housings, a handle for inserting a finger is formed on the right end. The tip of the bar blade is the same as a normal scissors (the part that becomes the front when closing the scissors) extends straight from the vicinity of the screw to the tip of the scissors, but the comb blade is a fine blade with a very short blade span. And the grooves are arranged alternately, literally comb-like.

ハンドルに指を差し入れて櫛刃と棒刃を閉じていくと、まず始めにネジの近傍で微細刃と棒刃の先端部同士が接触して、その後、閉じる操作を続けていくと、先端部同士の接触位置は鋏の先に移動していく。図6(B)は図6(A)の一部を拡大したもので、鋏を閉じていく際の櫛刃と棒刃の関係を示している。図の右側にある二個の微細刃は、既に先端部同士の接触を終えているが、右から三番目の微細刃は、矢印で示す右端で先端部同士の接触が始まった段階であり、さらに鋏を閉じていくと、先端部同士の接触位置は右端から中間部を経て左端に移動していく。なお、ネジよりも左側の全域で先端部同士の接触が発生するよう、櫛刃と棒刃の一方または両方に、図のようなネジリと呼ばれる緩い曲面を設けている。   When the finger is inserted into the handle and the comb blade and the bar blade are closed, the tips of the fine blade and the bar blade first come into contact with each other in the vicinity of the screw and then the closing operation is continued. The contact position between them moves to the tip of the heel. FIG. 6 (B) is an enlarged view of a part of FIG. 6 (A), and shows the relationship between the comb blade and the bar blade when the heel is closed. The two fine blades on the right side of the figure have already finished contact between the tip parts, but the third fine blade from the right is the stage where contact between the tip parts started at the right end indicated by the arrow, As the heel is further closed, the contact position between the tip portions moves from the right end to the left end via the intermediate portion. In addition, a loose curved surface called a torsion as shown in the figure is provided on one or both of the comb blade and the bar blade so that the tip portions contact each other in the entire region on the left side of the screw.

図7は、図6によるスキ鋏の刃の断面を示しており、図7(A)は頭髪を切断する原理で、図7(B)はトラブルが発生した状態である。図7(A)は、一個の微細刃に棒刃が接触して頭髪を切断する原理を時系列で並べており、棒刃の先端部には鋭利な刃先が形成されているが、対する微細刃の先端部は鋭利ではなく平面状で、その脇に棒刃を誘導するための逃げ面が形成されている。この逃げ面は、微細刃と溝が並ぶスキ鋏に特有のもので、棒刃が個々の微細刃と接触し始める際、棒刃が微細刃の先端部に乗り上げることを防止して、棒刃を微細刃の側面に誘導する役割がある。したがって厳密には、棒刃の先端部は、微細刃の先端部に接触するのではなく、逃げ面に接触している。なお通常の鋏は、ハンドルを閉じる際、二枚の刃の先端部が途切れることなく接触を維持するため、このような乗り上げが発生することはなく、逃げ面は不要である。   FIG. 7 shows a section of the blade of the skid according to FIG. 6, FIG. 7 (A) shows the principle of cutting the hair, and FIG. 7 (B) shows a state where trouble has occurred. FIG. 7 (A) shows the principle of cutting a head hair in contact with one fine blade in chronological order, and a sharp blade edge is formed at the tip of the rod blade. The tip of the slab is not sharp but flat, and a relief surface for guiding the bar blade is formed on the side. This flank is unique to skis with fine blades and grooves, and prevents the rod blade from riding on the tip of the fine blade when the rod blade starts to contact each fine blade. There is a role to guide to the side of the fine blade. Therefore, strictly speaking, the tip of the bar blade is not in contact with the tip of the fine blade but in contact with the flank. It should be noted that when the handle is closed, the tip of the two blades maintains contact without interruption when the handle is closed, so that such riding does not occur and a flank is unnecessary.

図のように棒刃が下降していくと、その先端部が逃げ面に接触して、この間に挟み込まれた頭髪が切断される。その後、棒刃は微細刃の側面に沿って下降していくが、その先端部が溝の底部に到達する前にハンドル同士が接触して操作が終了する。そのため、溝の中に入り込んだ頭髪は切断されることがない。なお図6および図7に示すスキ鋏は、あくまでも一例であり、これとは異なる構造の製品も存在している。   When the bar blade descends as shown in the figure, the tip of the bar blade comes into contact with the flank, and the hair that is sandwiched therebetween is cut. Thereafter, the bar blade descends along the side surface of the fine blade, but the operation comes to an end when the handles come into contact before the tip of the rod blade reaches the bottom of the groove. Therefore, the hair that has entered the groove is not cut. Note that the skies shown in FIGS. 6 and 7 are merely examples, and there are products having different structures.

スキ鋏については、これまでにも様々な技術開発が行われており、その例として以下のような特許文献が公開されている。特許文献1は、切断後の頭髪が毛羽立つことを防止して、斬新なヘアースタイルを創作できることを目的としており、棒刃の刃先に一本ないし複数の溝部を形成している。特許文献2は、頭髪の先端部分を先細に形成できることなどを目的としており、棒刃の刃先に切欠や第二切欠を設けている。特許文献3は、頭髪を痛めることなく所定のせん断性能が維持できることを目的としており、棒刃の先端に凹部を設けて、この凹部に限定して刃を形成している。特許文献4は、頭髪の切断作業を終えた後に鋏を移動させる際、切れ残った頭髪の損傷防止を目的としており、棒刃の先端には鋭利な刃を形成せず、櫛刃の先端部にのみ鋭利な刃を形成しており、先の背景技術で示した図6とは構造が異なる。

図7のように、棒刃の先端部が逃げ面に接触することで頭髪を切断している。したがって棒刃の先端部が鋭利であれば切断性に何らの問題もないが、使用によって先端部が磨耗していくと、棒刃の先端部が逃げ面を過ぎた段階でも頭髪の切断が完了せず、その後、頭髪を無理やり引き裂くような状態で切断が完了することがある。このような切れ味が悪くなった状態では、頭髪の切断面が鋭利でなくなり、しかも毛先の周辺に傷が付いて枝毛などの原因になるほか、ハンドルを閉じた後に鋏を移動する際、切断されていない頭髪を引き込んでしまうなど、様々なトラブルを招くことになる。   As shown in FIG. 7, the hair is cut by the tip of the bar blade contacting the flank. Therefore, if the tip of the bar blade is sharp, there will be no problem in cutting performance, but if the tip is worn out by use, the cutting of the hair is completed even when the tip of the bar blade passes the flank. After that, the cutting may be completed in such a state that the hair is forcibly torn. In such a state of sharpness, the cut surface of the hair is not sharp, and there are scratches around the hair tip, causing split ends, etc.When moving the eyelid after closing the handle, It will cause various troubles, such as drawing in uncut hair.

このようにスキ鋏の切れ味が悪くなると、作業者は半ば無意識のうちに、図6(A)の矢印に示すような力をハンドルに加えることがある。この力は、鋏体の回動方向に対して直交する方向であり、櫛刃と棒刃の密着性が高まり切れ味が改善する。しかしこの力が過度になると、櫛刃と棒刃の重なりが増加して、図7(B)のように、棒刃が微細刃の先端部に乗り上げてしまう場合がある。乗り上げが発生すると、切断が中途半端な状態で終了して適正な作業が困難になり、しかも棒刃の先端部に過大な荷重が作用して、刃先の変形や脱落といった回復不能な破損が発生することもある。   If the sharpness of the skies becomes worse in this way, the operator may unintentionally apply force as indicated by the arrow in FIG. 6A to the handle. This force is a direction orthogonal to the rotation direction of the housing, and the adhesion between the comb blade and the bar blade is increased, and the sharpness is improved. However, when this force becomes excessive, the overlap between the comb blade and the bar blade increases, and the bar blade may ride on the tip of the fine blade as shown in FIG. 7B. When riding up, cutting is terminated halfway, making proper work difficult, and excessive load is applied to the tip of the bar blade, causing irreparable damage such as deformation or dropping of the blade edge. Sometimes.

本発明はこうした実情を基に開発されたもので、刃の先端部の破損を防止でき、しかも切断性能にも優れたスキ鋏の提供を目的としている。   The present invention has been developed based on such a situation, and an object of the present invention is to provide a skid that can prevent the tip of the blade from being damaged and is excellent in cutting performance.

前記の課題を解決するための請求項1記載の発明は、微細刃と溝が交互に並ぶ櫛刃を有する第一鋏体と、先端部が線状に延びている棒刃を有する第二鋏体と、がネジを支点として回動可能に一体化されており、個々の微細刃の先端部には刃先が形成されており、また棒刃の先端部には、櫛刃と対面する内側面から遠ざかるに連れて最先端から後退していく傾斜面が形成され、該傾斜面と内側面との角部に刃先が形成されており、且つ棒刃と個々の微細刃との接触開始位置には、傾斜面から突出する突出片が形成され、該突出片には、傾斜面から遠ざかるに連れて内側面から後退していく逃げ面が形成されていることを特徴とするスキ鋏である。   The invention according to claim 1 for solving the above-mentioned problem is a second rod having a first blade having a comb blade in which fine blades and grooves are alternately arranged, and a rod blade having a tip extending linearly. The body is integrated with a screw as a fulcrum so that it can rotate, and the tip of each fine blade is formed with a cutting edge, and the tip of the bar blade has an inner surface facing the comb blade. An inclined surface that recedes from the leading edge as it moves away from the tip is formed, and a cutting edge is formed at the corner between the inclined surface and the inner surface, and at the contact start position between the bar blade and each fine blade Is a skid characterized in that a projecting piece projecting from an inclined surface is formed, and a flank that recedes from the inner surface as the distance from the tilted surface is formed on the projecting piece.

本発明のスキ鋏についても、その基本的な構成は従来の物と同一であり、第一鋏体と第二鋏体の二部品がネジによって回動可能に一体化されており、両鋏体とも、ネジを中心として一方の側には指を差し入れるためのハンドルが形成されており、他方の側には切断作業を実現するため、第一鋏体には櫛刃が、第二鋏体には棒刃が形成されている。櫛刃は文字通り櫛状に形成されたもので、刃渡りが数ミリ程度の微細刃が溝を隔てて連続的に並んでいる。また棒刃は、通常の鋏と同様、細長断面が連続した単純な形状で、その先端部は、ネジ付近から鋏の先まで、直線あるいは緩やかな曲面で構成されている。なお先端部とは、櫛刃および棒刃において、鋏を閉じる際に前面となる部分を指している。   The basic structure of the ski of the present invention is the same as that of the prior art, and the two parts of the first housing and the second housing are integrated so as to be rotatable by screws. In both cases, a handle for inserting a finger is formed on one side with the screw at the center, and a comb blade is provided on the first case, and a second blade is provided on the other side in order to realize a cutting operation. A bar blade is formed in the. The comb blade is literally formed in a comb shape, and fine blades with a blade span of several millimeters are continuously arranged with a groove therebetween. In addition, the bar blade has a simple shape with a long and narrow cross section, like a normal scissors, and its tip end portion is composed of a straight line or a gentle curved surface from the vicinity of the screw to the tip of the scissors. In addition, the front-end | tip part has pointed out the part which becomes a front surface when closing a scissors in a comb blade and a bar blade.

櫛刃は、前記のように微細刃と溝が連続して並ぶ構成であり、本発明では、全ての微細刃の先端部に鋭利な刃先が形成されている。対する棒刃は、櫛刃と対面して擦れ合う面を内側面と規定しており、この内側面の角に位置する先端部には、平面状の傾斜面が形成されている。傾斜面は、内側面から遠ざかるに連れて、最先端(内側面と傾斜面との交点)から後退するように傾いているものとする。したがって先端部を上に向けた状態で棒刃の断面を見ると、上面が傾斜面であり、傾斜面と内側面は鋭角状に交差している。さらに本発明では、この鋭角状の交差部に鋭利な刃先が形成されている。なお傾斜面は、ネジ付近から鋏の先まで連続している必要はなく、櫛刃の溝に差し掛かる部分は、実際の切断に関与しないため、この区間を省略して断続的に面が並ぶ形態でも良い。   The comb blade has a configuration in which the fine blade and the groove are continuously arranged as described above, and in the present invention, a sharp blade edge is formed at the tip of all the fine blades. On the other hand, the bar blade defines a surface that rubs against the comb blade as an inner surface, and a flat inclined surface is formed at the tip located at the corner of the inner surface. The inclined surface is inclined so as to recede from the leading edge (intersection of the inner surface and the inclined surface) as it moves away from the inner surface. Therefore, when the section of the bar blade is viewed with the tip portion facing upward, the upper surface is an inclined surface, and the inclined surface and the inner surface intersect at an acute angle. Furthermore, in the present invention, a sharp cutting edge is formed at the acute angle intersection. Note that the inclined surface does not need to be continuous from the vicinity of the screw to the tip of the hook, and the portion that reaches the groove of the comb blade is not involved in the actual cutting, so the surface is intermittently arranged by omitting this section. Form may be sufficient.

突出片は、棒刃の傾斜面から***するように形成されるもので、櫛刃と棒刃を閉じていく際、棒刃が個々の微細刃と接触し始める位置に設けられる。したがって突出片は、個々の微細刃に対応して、所定の間隔で並ぶように配置される。なお突出片の具体的な大きさや各部の形状については、微細刃の刃先を誘導する機能が発揮できるならば何らの制約もなく、棒状や角錐形などを自在に選択できる。ただしいずれの形状の場合も、内側面に隣接している必要がある。   The protruding piece is formed so as to protrude from the inclined surface of the bar blade, and is provided at a position where the bar blade starts to come into contact with each fine blade when the comb blade and the bar blade are closed. Therefore, the protruding pieces are arranged so as to be arranged at predetermined intervals corresponding to the individual fine blades. As for the specific size of the protruding piece and the shape of each part, there is no restriction as long as the function of guiding the cutting edge of the fine blade can be exhibited, and a rod shape or a pyramid shape can be freely selected. However, in any case, it is necessary to be adjacent to the inner surface.

逃げ面は、突出片の各側面のうち、棒刃の内側面に接している面であり、傾斜面から遠ざかるに連れて内側面から後退していくように形成される。この逃げ面と内側面との境界は、曲面で滑らかに仕上げることも可能だが、角を残していても構わない。なお、傾斜面から遠ざかるに連れて内側面から後退していくとは、逃げ面が内側面の奥に引き下がるように傾いていることを意味する。   The flank surface is a surface that is in contact with the inner surface of the bar blade among the side surfaces of the protruding piece, and is formed so as to recede from the inner surface as the distance from the inclined surface increases. The boundary between the flank and the inner surface can be smoothly finished with a curved surface, but the corner may remain. Note that retreating from the inner surface as it moves away from the inclined surface means that the flank is inclined so as to be pulled down to the back of the inner surface.

このように構成することで、切断作業のために櫛刃と棒刃を閉じていく際、棒刃に形成された突出片の逃げ面が微細刃と最初に接触するため、微細刃の先端部は、確実に棒刃の内側面に誘導され、従来のような乗り上げを防止できる。しかも突出片が微細刃の誘導を終えた後は、微細刃の刃先と棒刃の刃先が押し合うように接触するため、挟み込まれた頭髪は、両側から切断される。この双方の刃先が押し合う位置は、鋏を閉じていくに連れて、先の方に移動していき、その間切断作業が継続する。なお突出片は、原則として微細刃と同数を形成する必要がある。   By configuring in this way, when closing the comb blade and the bar blade for cutting work, the flank of the protruding piece formed on the bar blade comes into contact with the micro blade first, so the tip of the micro blade Is reliably guided to the inner surface of the bar blade and can prevent the conventional ride-up. Moreover, after the protruding piece finishes guiding the fine blade, the fine blade edge and the bar blade edge come into contact with each other so that the sandwiched hair is cut from both sides. The position where both of the blade edges are pressed moves toward the tip as the heel is closed, and the cutting operation continues during that time. In principle, it is necessary to form the same number of protruding pieces as fine blades.

請求項1記載の発明のように、櫛刃を構成する個々の微細刃の先端部に鋭利な刃先を形成した上、棒刃の傾斜面には、個々の微細刃との接触開始位置に、逃げ面を有する突出片を形成することで、微細刃の先端部が棒刃の内側面に誘導されるため、櫛刃が棒刃に乗り上げることを防止できる。そのため鋏を確実に閉じることができ、しかも刃先が破損することもない。   As in the first aspect of the invention, a sharp cutting edge is formed at the tip of each fine blade constituting the comb blade, and the inclined surface of the bar blade is at a contact start position with each fine blade, By forming the protruding piece having the flank, the tip of the fine blade is guided to the inner surface of the bar blade, so that the comb blade can be prevented from riding on the bar blade. Therefore, the heel can be closed reliably and the cutting edge is not damaged.

また棒刃は、内側面と傾斜面との交差部に鋭角状の刃先が形成されており、しかも逃げ面の作用により、微細刃の先端は、必ずこの刃先に到達する。この双方の刃先が接触する瞬間は、頭髪の両側に刃先が食い込み、さらに刃先同士が押し合う状態になるため、頭髪は極めて円滑に切断され、毛先の周辺を痛めることがなく、しかも鋏を閉じた後に頭部から離す際、頭髪を引き込むこともない。   The rod blade has an acute-angled blade edge formed at the intersection of the inner surface and the inclined surface, and the tip of the fine blade always reaches the blade edge by the action of the flank. At the moment when both cutting edges come into contact with each other, the cutting edges bite into both sides of the hair, and the cutting edges are pressed against each other, so the hair is cut very smoothly, without damaging the periphery of the hair and without wrinkles. It does not pull in the hair when it is released from the head after closing.

図1は、本発明の構成を示しており、図1(A)はスキ鋏10全体の形状のほか櫛刃12と棒刃22の一部を拡大したもので、図1(B)は微細刃13と棒刃22が接触する直前の状態で、図1(C)は図1(B)の後、微細刃13と棒刃22が接触した状態である。図1(A)の全体形状に示すように、本発明によるスキ鋏10は、一端寄りに櫛刃12が形成され他端寄りにハンドル32が形成された第一鋏体11と、一端寄りに棒刃22が形成され、他端寄りにハンドル32が形成された第二鋏体21と、で構成され、両鋏体11、21とも鋼鉄を一体的に加工したものである。個々の鋏体11、21の中央付近には、双方を一体化するためのネジ31が挿通されており、それぞれが自在に回動できる構造になっている。なお本図のハンドル32は、鋏体11、21と一体で成形されているが、ハンドル32だけを別途に製作して、接合などで一体化する場合もある。またネジ31よりも左側は、実際に頭髪を切断するための機能を有しており、この部分全体について、第一鋏体11では櫛刃12、第二鋏体21では棒刃22と称するものとする。   FIG. 1 shows the configuration of the present invention. FIG. 1 (A) is an enlarged view of the shape of the skimmer 10 as well as a part of the comb blade 12 and the bar blade 22. FIG. FIG. 1C shows a state immediately after the blade 13 and the rod blade 22 come into contact with each other, and FIG. As shown in the overall shape of FIG. 1A, a skid 10 according to the present invention has a first housing 11 in which a comb blade 12 is formed near one end and a handle 32 is formed near the other end. The rod body 22 is formed, and the second housing 21 is formed with a handle 32 near the other end. Both the housings 11 and 21 are formed by integrally processing steel. In the vicinity of the center of each of the housings 11 and 21, a screw 31 for integrating both is inserted, and each has a structure that can freely rotate. Although the handle 32 in this figure is formed integrally with the housings 11 and 21, there may be a case where only the handle 32 is separately manufactured and integrated by joining or the like. The left side of the screw 31 has a function for actually cutting the hair, and the entire portion is referred to as a comb blade 12 in the first casing 11 and a bar blade 22 in the second casing 21. And

図1(A)の拡大図のように、櫛刃12は、刃渡りの短い微細刃13が溝14を隔てて連続的に並んだ櫛形になっており、各微細刃13の先端付近は棒刃22側に湾曲しており、さらに鋭利な刃先15が形成されている。対する棒刃22は、細長断面の単純な板状であり、そのうち櫛刃12に対面している領域を内側面23と称するものとするほか、図の底部に傾斜面24が形成されている。傾斜面24は、内側面23から遠ざかるに連れて、棒刃22の最先端から後退する方向に傾いているため、傾斜面24と内側面23は鋭角状に交差しており、この箇所にも鋭利な刃先25が形成されている。なお内側面23とは逆の裏面28側については、傾斜面24との接続部分が滑らかな円弧状に仕上げられている。   As shown in the enlarged view of FIG. 1A, the comb blade 12 has a comb shape in which fine blades 13 having a short span are continuously arranged with a groove 14 therebetween. A sharp cutting edge 15 is formed which is curved toward the side 22. On the other hand, the bar blade 22 has a simple plate shape with an elongated cross section, and a region facing the comb blade 12 is referred to as an inner side surface 23, and an inclined surface 24 is formed at the bottom of the figure. The inclined surface 24 and the inner side surface 23 intersect at an acute angle because the inclined surface 24 is inclined in the direction of retreating from the forefront of the bar blade 22 as the distance from the inner side surface 23 increases. A sharp cutting edge 25 is formed. In addition, about the back surface 28 side opposite to the inner surface 23, the connection part with the inclined surface 24 is finished in the smooth circular arc shape.

傾斜面24は単純な平面ではなく、この面から***した突出片26が並んで形成されている。この突出片26は、櫛刃12と棒刃22が閉じていく際、棒刃22が個々の微細刃13と接触し始める位置に限定して配置されており、しかも突出片26の一側面には、内側面23から連続する逃げ面27が形成されている。逃げ面27は、突出片26の先端(図の下方)に向かうに連れて、内側面23よりも後退するように傾いており、接触する微細刃13を棒刃22の内側面23に誘導することができる。したがって逃げ面27と内側面23との間には、微細刃13の移動を拘束する段差などはない。   The inclined surface 24 is not a simple flat surface, but is formed with protruding pieces 26 protruding from this surface. The protruding piece 26 is disposed only at a position where the bar blade 22 starts to come into contact with each fine blade 13 when the comb blade 12 and the bar blade 22 are closed. Is formed with a flank 27 continuous from the inner surface 23. The flank 27 is inclined so as to recede from the inner surface 23 toward the tip of the protruding piece 26 (downward in the figure), and guides the contacting fine blade 13 to the inner surface 23 of the bar blade 22. be able to. Therefore, there is no step or the like that restrains the movement of the fine blade 13 between the flank 27 and the inner surface 23.

図1(B)は、棒刃22の一部分と一個の微細刃13だけを抽出して描いており、突出片26の機能を示している。突出片26は、櫛刃12と棒刃22を閉じていく際、棒刃22が微細刃13と接触し始める位置に形成されているため、微細刃13の右端の真上に位置している。また鋏は、図6に示す従来技術のようにネジリが与えられているため、微細刃13の刃先15は、棒刃22の内側面23よりも奥側に入り込んでいる。そのため双方の刃先15、25が接触する直前の時点で、微細刃13の刃先15が突出片26の逃げ面27に接触して、その後、微細刃13の刃先15は逃げ面27に沿って移動していき、やがて内側面23に到達する。   FIG. 1B shows only a part of the bar blade 22 and one fine blade 13, and shows the function of the protruding piece 26. The protruding piece 26 is formed at a position where the bar blade 22 starts to come into contact with the fine blade 13 when the comb blade 12 and the bar blade 22 are closed, and is thus located immediately above the right end of the fine blade 13. . Further, since the scissors are provided with a twist as in the prior art shown in FIG. 6, the cutting edge 15 of the fine blade 13 is deeper than the inner surface 23 of the bar blade 22. Therefore, immediately before the two cutting edges 15 and 25 come into contact with each other, the cutting edge 15 of the fine blade 13 contacts the flank 27 of the protruding piece 26, and then the cutting edge 15 of the fine blade 13 moves along the flank 27. Then, it eventually reaches the inner surface 23.

図1(C)は、図1(B)の後、さらに櫛刃12と棒刃22を閉じていった状態であり、突出片26は、既に微細刃13の刃先15よりも下に位置しており、微細刃13を誘導する役割を終えている。そして微細刃13の中央付近では、双方の刃先15、25が対向するように接触している。この際は、ネジリによって刃先15、25同士が押し付け合っているため、間に挟み込まれた頭髪は容易に切断される。   FIG. 1C shows a state in which the comb blade 12 and the bar blade 22 are further closed after FIG. 1B, and the protruding piece 26 is already positioned below the cutting edge 15 of the fine blade 13. The role of guiding the fine blade 13 is finished. In the vicinity of the center of the fine blade 13, both the blade edges 15 and 25 are in contact with each other. At this time, since the blade edges 15 and 25 are pressed against each other by twisting, the hair sandwiched between them is easily cut.

図2は、図1に描かれた棒刃22の詳細を示しており、図2(A)は棒刃22の傾斜面24を上に向けており、図2(B)は図2(A)のB−B断面で、図2(C)は図2(A)のC−C断面で、図2(D)は図2(A)のD方向から見た側面である。図2(A)のように、棒刃22の上面には、内側面23を頂点として下方に進む傾斜面24が形成されており、この面上に突出片26が等間隔で並んでいる。また図2(B)は、突出片26が形成されている部分の断面図であり、突出片26には内側面23から次第に後退していく逃げ面27が形成されている。なお逃げ面27と内側面23との境界は、鈍角状に折れ曲がっている。次に図2(C)は、突出片26が形成されていない部分の断面図であり、傾斜面24と内側面23との交差部は、面取りなどの処理がされておらず、鋭角状の刃先25が形成されている。したがってこの部分も、微細刃13の刃先15と同様、頭髪に食い込んでいくことができる。そのほか、傾斜面24と裏面28との境界については形状に制約がなく、円弧で滑らかに結んでいる。   2 shows details of the bar blade 22 depicted in FIG. 1, FIG. 2 (A) shows the inclined surface 24 of the bar blade 22 facing upward, and FIG. 2 (B) shows FIG. 2 (A). 2B is a cross-sectional view taken along the line CC in FIG. 2A, and FIG. 2D is a side view as viewed from the direction D in FIG. 2A. As shown in FIG. 2A, the upper surface of the bar blade 22 is formed with an inclined surface 24 that proceeds downward with the inner surface 23 as an apex, and projecting pieces 26 are arranged at equal intervals on this surface. FIG. 2B is a cross-sectional view of a portion where the protruding piece 26 is formed. The protruding piece 26 has a flank 27 that gradually retreats from the inner surface 23. The boundary between the flank 27 and the inner surface 23 is bent in an obtuse angle. Next, FIG. 2C is a cross-sectional view of a portion where the protruding piece 26 is not formed, and the intersection of the inclined surface 24 and the inner surface 23 is not subjected to chamfering or the like and has an acute angle shape. A cutting edge 25 is formed. Therefore, this portion can also penetrate into the hair like the cutting edge 15 of the fine blade 13. In addition, the boundary between the inclined surface 24 and the back surface 28 is not limited in shape, and is smoothly connected by an arc.

図2(D)は、棒刃22を内側面23の方から見たもので、図の左側にネジ31があるものとする。櫛刃12と棒刃22を閉じていく際、棒刃22は、微細刃13のネジ31側から接触を開始する。そのため突出片26は、微細刃13の左端に接触する位置に形成されており、その間隔は当然ながら微細刃13の間隔に一致する。なお突出片26の間隔は2mm程度だが、突出片26の長さは0.2mm程度、高さも0.2mm程度であり、微細刃13と比較しても格段に小さい。   FIG. 2D shows the rod blade 22 as viewed from the inner side surface 23, and it is assumed that there is a screw 31 on the left side of the figure. When the comb blade 12 and the bar blade 22 are closed, the bar blade 22 starts contact from the screw 31 side of the fine blade 13. Therefore, the protruding piece 26 is formed at a position in contact with the left end of the fine blade 13, and the interval thereof naturally matches the interval of the fine blade 13. Although the interval between the protruding pieces 26 is about 2 mm, the length of the protruding pieces 26 is about 0.2 mm and the height is about 0.2 mm, which is much smaller than the fine blade 13.

図3は、本発明によるスキ鋏10の動作原理を時系列で示すため、櫛刃12および棒刃22の端面を描いたもので、図3(A)は突出片26が形成されている部分で、図3(B)は突出片26が形成されていない部分である。両図とも左から右に進むに連れて、棒刃22が下方に移動していく。図3(A)では、まず微細刃13の刃先15に棒刃22の突出片26が接近していき、やがて突出片26の逃げ面27に、微細刃13の刃先15が接触する。その後、微細刃13の刃先15は逃げ面27に沿って移動していくが、この際、微細刃13は逃げ面27によって押し戻されるような荷重を受けるため、微細刃13の刃先15は逃げ面27との接触を維持しながら、やがて内側面23に移動していく。   FIG. 3 depicts the end surfaces of the comb blade 12 and the bar blade 22 in order to show the operation principle of the skimmer 10 according to the present invention in time series. FIG. 3A shows a portion where the protruding piece 26 is formed. FIG. 3B shows a portion where the protruding piece 26 is not formed. In both figures, the bar blade 22 moves downward as it proceeds from left to right. In FIG. 3A, first, the protruding piece 26 of the bar blade 22 approaches the cutting edge 15 of the fine blade 13, and eventually the cutting edge 15 of the fine blade 13 contacts the flank 27 of the protruding piece 26. Thereafter, the cutting edge 15 of the fine blade 13 moves along the flank 27. At this time, since the fine blade 13 receives a load that is pushed back by the flank 27, the cutting edge 15 of the fine blade 13 is flank. While maintaining contact with 27, it eventually moves to the inner surface 23.

図3(B)は、突出片26が形成されていない部分での微細刃13と棒刃22との関係を示しており、一番左側の状態では、微細刃13の刃先15の真上に棒刃22の傾斜面24が位置しており、さらに左から二番目のように、棒刃22が微細刃13に接触する直前でも、刃先15の上を傾斜面24が覆っている。しかしその後、図3(A)のように、微細刃13の刃先15が突出片26に接触して、以降は櫛刃12と棒刃22が押し戻されるように変形する。そのため図3(B)の左から三番目のように、必然的に棒刃22の刃先25と微細刃13の刃先15が一致して押し合う瞬間が発生する。この時、双方の間に頭髪が挟み込まれていれば、その両側から刃先15、25が食い込んでいき、頭髪は速やかに切断される。この双方の刃先15、25が押し合う位置は、鋏を閉じていくに連れて、微細刃13の刃渡り方向に移動していき、その間切断作業が継続する。   FIG. 3B shows the relationship between the fine blade 13 and the bar blade 22 at a portion where the protruding piece 26 is not formed. In the leftmost state, the blade is directly above the cutting edge 15 of the fine blade 13. The inclined surface 24 of the bar blade 22 is located, and the inclined surface 24 covers the blade edge 15 even immediately before the bar blade 22 contacts the fine blade 13 as the second from the left. However, thereafter, as shown in FIG. 3A, the cutting edge 15 of the fine blade 13 comes into contact with the protruding piece 26, and thereafter, the comb blade 12 and the bar blade 22 are deformed so as to be pushed back. For this reason, the third moment from the left in FIG. 3B inevitably occurs when the cutting edge 25 of the bar blade 22 and the cutting edge 15 of the fine blade 13 are matched and pressed. At this time, if the hair is sandwiched between the two, the cutting edges 15 and 25 bite in from both sides, and the hair is quickly cut. The position where both the blade edges 15 and 25 are pressed moves in the crossing direction of the fine blade 13 as the blade is closed, and the cutting operation is continued during that time.

図4は、突出片26の形状例を示しており、図4(A)は角錐形で、図4(B)は円錐形である。突出片26は、逃げ面27によって微細刃13の刃先15を円滑に誘導できるならば、その形状は自在であり、図1などに示す箱状のほか、本図のように角錐形や円錐形などでも構わない。なお傾斜面24については、必ずしも図4(A)のように全域を平面状とする必要はなく、櫛刃12の溝14に差し掛かるため頭髪の切断に関与しない部分では、図4(B)のように、凹部33などを設けることも可能であり、傾斜面24が分断されることもある。当然ながら凹部33には刃先25を形成できない。   FIG. 4 shows an example of the shape of the protruding piece 26. FIG. 4A shows a pyramid shape, and FIG. 4B shows a conical shape. The protruding piece 26 can have any shape as long as the cutting edge 15 of the fine blade 13 can be smoothly guided by the flank 27. In addition to the box shape shown in FIG. 1 and the like, the protruding piece 26 has a pyramid shape or a cone shape as shown in FIG. It doesn't matter. Note that the inclined surface 24 does not necessarily have to be flat as shown in FIG. 4A, and the portion that does not participate in the cutting of the hair because it reaches the groove 14 of the comb blade 12 is shown in FIG. As described above, the recess 33 or the like can be provided, and the inclined surface 24 may be divided. Naturally, the cutting edge 25 cannot be formed in the recess 33.

図5は、図1とは異なる本発明の形態例を示しており、図5(A)は全体で、図5(B)は櫛刃12と棒刃22の一部を拡大したものである。図1では棒刃22の突出片26は、微細刃13のネジ31側に接触していた。しかし本図の微細刃13の刃先15は、ネジ31の方に進むに連れて後退していくような傾きが付いている。この場合、櫛刃12と棒刃22を閉じていくと、各微細刃13の左端(ネジ31から最も遠い位置)から棒刃22が接触していく。そのため図5(B)のように、突出片26は、微細刃13の刃先15のうちネジ31から遠い方の端部に接触するように配置されている。   5 shows an embodiment of the present invention different from FIG. 1, FIG. 5 (A) is the whole, and FIG. 5 (B) is an enlarged view of a part of the comb blade 12 and the bar blade 22. . In FIG. 1, the protruding piece 26 of the bar blade 22 is in contact with the screw 31 side of the fine blade 13. However, the cutting edge 15 of the fine blade 13 in this figure is inclined so as to recede as it advances toward the screw 31. In this case, when the comb blade 12 and the bar blade 22 are closed, the bar blade 22 comes into contact with the left end of each fine blade 13 (the position farthest from the screw 31). Therefore, as shown in FIG. 5B, the protruding piece 26 is disposed so as to come into contact with the end portion farther from the screw 31 in the cutting edge 15 of the fine blade 13.
