Description

本発明は、理髪店や美容院等で使用される理美容用の鋏に関するものである。   The present invention relates to a barber for hairdressing and beauty used in a barber shop or a hair salon.

従来より、理髪店や美容院等で鋏を使用して髪をカットする際、いわゆる「髪が逃げる」現象への対処が問題となっていた。この「髪が逃げる」現象とは、一対の鋏刃から加えられた力により、髪が刃先方向に移動する現象である。ここで、髪が逃げようとする力は、一対の鋏刃が髪を切断する位置において、一方の鋏刃と他方の鋏刃によって形成される角度「閉じ角」によって変化し、この閉じ角が大きい程大きくなる。すなわち、刃元近くで髪を切断する場合に髪はより逃げやすく、刃先近くでは、髪は一対の刃に挟み込まれた状態となり、逃げにくくなる。   Conventionally, when hair is cut using a scissors in a barber shop or a hair salon, it has been a problem to deal with the phenomenon of so-called “hair escape”. This “hair escape” phenomenon is a phenomenon in which hair moves in the direction of the blade edge by the force applied from a pair of scissors blades. Here, the force with which the hair tries to escape changes at the position where the pair of scissors blades cuts the hair, depending on the angle “closing angle” formed by one scissors blade and the other scissors blade, and this closing angle is The bigger it is, the bigger it becomes. That is, when the hair is cut near the blade base, the hair is more likely to escape, and near the blade tip, the hair is sandwiched between the pair of blades, making it difficult to escape.

従って、櫛で髪を抑えたり、鋏を使用していない方の手指で髪を挟み込むことにより、髪を逃げにくくしたとしても、一回の切断操作で切断された髪において、刃元付近で切断された髪と刃先付近で切断された髪とでは長さが不揃いになりやすい。そのため、髪を同じ長さにそろえるために、一回の操作で切断する幅を小さくし、鋏を激しく動かして同じ位置を何度も切ったり、髪を逃がしにくくするために髪を濡らして髪同士を接着させてカットすることが行われている。また、髪を逃がしにくい鋏の改良も行われている。   Therefore, even if the hair is difficult to escape by holding the hair with a comb or holding the hair with a finger not using a scissors, the hair cut by a single cutting operation is cut near the blade edge. The length of the cut hair and the hair cut near the blade edge are likely to be uneven. Therefore, in order to align the hair to the same length, the width of cutting in one operation is reduced, the hair is moved violently to cut the same position many times, and the hair is wetted to make it difficult to escape. It is performed by bonding them together and cutting them. In addition, wrinkles that make it difficult to escape hair have been improved.

ところが、髪を逃がさずに一様な長さに切り揃えた髪は、直線的で硬い印象を与えることから、最近では、自然な仕上がりの柔らかいイメージの髪型を要望する顧客も多い。そこで、髪の長さをわずかに変化させて毛先のラインをぼかし柔らかな仕上がりとしたり、動きや軽さを表現するために、敢えて髪の長さを不規則なものとするシャギーやレイヤー等の技法によるカットが行われている。また、髪が乾いた状態で、髪を逃がしやすくしてカットすることも行われている。その他、刃幅をアールを付けて変化させた刃(笹刃)を使用し、刃幅が刃元から刃先にかけて直線的に減少する従来の鋏に比べて閉じ角を大きくした鋏も使用されている。   However, hair that has been trimmed to a uniform length without escaping the hair gives a straight and hard impression, and recently there are many customers who desire a hairstyle with a soft image with a natural finish. Therefore, shaggy or layers that intentionally make the hair length irregular in order to slightly change the length of the hair and blur the tip line to create a soft finish or to express movement and lightness. Cut by the technique of. In addition, it is also performed to make hair easy to escape while the hair is dry. In addition, using a blade with a rounded blade width (a blade), a blade with a larger closing angle is also used compared to a conventional blade in which the blade width decreases linearly from the blade edge to the blade edge. Yes.

上記の技術は、当業者においては当然のごとく知られているものであり、本出願人は、本願出願時において、上記の技術が記載されている文献を知見していない。   The above-described technique is naturally known to those skilled in the art, and the present applicant does not know a document describing the above-described technique at the time of filing this application.

しかしながら、従来の鋏では、美容師等の鋏の使用者自身が行うことのできる調整は、枢着部のネジの締付け具合を変化させ、「ため」の力(一対の鋏刃の接触圧力)を調整する程度に限定された。すなわち、鋏の使用者が閉じ角を自分で調整することはできなかった。そのため、目的とする髪形に合わせて、髪の逃げやすさを能動的に変化させ、毛先の処理に微妙な変化をつけることは困難であった。   However, with conventional scissors, adjustments that can be performed by a scissors user, such as a beautician, change the tightening condition of the screws in the pivoting portion, thereby increasing the force for the purpose (contact pressure between a pair of scissors blades). The degree of adjustment was limited. That is, the user of the heel could not adjust the closing angle by himself. For this reason, it has been difficult to actively change the ease of hair escape according to the target hairstyle and to make a subtle change in the treatment of the hair tips.

また、同じ閉じ角でも、刃の摩耗により刃が髪を捕えにくくなるため髪が逃げやすくなる。そのため、ある程度髪を逃がしやすいように設計された鋏も、鋏の使用による刃の摩耗に伴って仕上がりが異なって来てしまう問題があった。   In addition, even with the same closing angle, the blade is less likely to catch the hair due to wear of the blade, so that the hair can easily escape. For this reason, wrinkles designed to allow hair to escape to some extent have a problem that the finish differs with the wear of the blades due to the use of the wrinkles.

そこで、本発明は上記の実情に鑑み、美容師等の鋏の使用者が、自ら、閉じ角を変化させ調整することができる鋏の提供を課題とするものである。   Therefore, in view of the above circumstances, an object of the present invention is to provide a cocoon that can be used by a cocoon user such as a hairdresser to change and adjust the closing angle.

本発明に係る鋏は、「夫々刃部及び持部を有する一対の鋏片と、前記刃部と前記持部との間に位置し、一対の前記鋏片を軸芯周りに回動可能に互いに枢着する枢着部と、一対の前記鋏片の前記刃部が物を切断する任意の切断位置において一方の前記刃部が他方の前記刃部と形成する閉じ角を、変化させて調整可能とする閉じ角調整手段と」を主に具備して構成されている。   The scissors according to the present invention are “located between a pair of scissors each having a blade part and a holding part, and the blade part and the holding part, so that the pair of scissors can be rotated around an axis. Adjusting by changing the closing angle formed by one blade part with the other blade part at any cutting position where the blade parts of the pair of hook pieces and the blade parts of the pair of scissors cut an object. The closing angle adjusting means that can be used "is mainly provided.

ここで、閉じ角調整手段は、枢着部において一方の鋏片における軸芯の位置を他方の鋏片に対して相対的に変化させるものを例示することができる。また、少なくとも一方の鋏片において刃部を持部と別体に形成し、両者が当接して一部重なり合う部分において一方を他方にネジ等により取付け、その取付け角度を可変とする機構(例えば、ネジと長孔との組合わせ等)を備えることにより、閉じ角を調整可能とするものを例示することもできる。   Here, the closing angle adjusting means can be exemplified by a mechanism that changes the position of the shaft core in one hook piece relative to the other hook piece in the pivot portion. Further, a mechanism in which the blade portion is formed separately from the holding portion in at least one of the scissors pieces, and one of them is attached to the other with a screw or the like in a portion where both of them abut and partially overlap (for example, the attachment angle is variable) A combination of a screw and a long hole, etc.) can be used to adjust the closing angle.

従って、本発明によれば、閉じ角調整手段を具備することにより、美容師等の鋏の使用者自身が、閉じ角を変化させることが可能となる。これにより、髪の逃げやすさを能動的に変化させて調整し、多様な髪型を表現することが容易となる。   Therefore, according to the present invention, by providing the closing angle adjusting means, it is possible for the user of the heel such as a beautician to change the closing angle. This makes it easy to express various hairstyles by actively changing and adjusting the ease of hair escape.

また、鋏の使用により刃部が摩耗した場合、閉じ角を微調整することにより、髪の逃げやすさについての所望の設定を維持することが可能となる。   In addition, when the blade portion is worn due to the use of the heel, it is possible to maintain a desired setting for the ease of hair escape by finely adjusting the closing angle.

さらに、本発明に係る鋏は、「前記閉じ角調整手段は、前記枢着部において一方の前記鋏片における前記軸芯の位置を、他方の前記鋏片に対して相対的に変化させる軸位置調整手段である」ものとすることもできる。   Further, the scissors according to the present invention are as follows: "The closing angle adjusting means is an axial position for changing the position of the shaft core in one of the scissors pieces relative to the other scissor piece in the pivoting portion. It can also be “adjustment means”.

ここで、軸位置調整手段は、一方の鋏片において軸芯の位置を固定し、他方の鋏片に対して軸芯位置を可変とするものであり、例えば、一方の鋏片において枢着部に複数の孔部を穿設し、そのいずれかに軸芯を挿通し、その軸芯をネジ等で係止するものが例示される。これにより、軸芯を挿通した孔の位置を中心として一対の鋏片が回動することとなり、設けた孔部の位置及び数に応じて閉じ角を変化させることが可能となる。このとき、軸芯の位置が固定されている方の鋏片において、軸芯は鋏片に挿通され、その挿通孔において回転する軸芯が一対の鋏片の回動中心となるものとすることもでき、また、軸芯自体は鋏片に固着され、軸芯に挿通されるネジ等に回動中心となる部分が設けられるものとすることもできる。   Here, the shaft position adjusting means is configured to fix the position of the shaft core in one collar piece and to change the position of the shaft core relative to the other collar piece. A plurality of holes are drilled, a shaft core is inserted into one of them, and the shaft core is locked with a screw or the like. As a result, the pair of hooks rotate around the position of the hole inserted through the shaft core, and the closing angle can be changed according to the position and number of the holes provided. At this time, in the hook piece with the fixed position of the shaft core, the shaft core is inserted into the hook piece, and the shaft core rotating in the insertion hole becomes the rotation center of the pair of hook pieces. In addition, the shaft core itself may be fixed to the flange piece, and a screw or the like inserted through the shaft core may be provided with a portion serving as a rotation center.

また、上記の複数の孔部の間に連通孔を設け、いずれかの孔部に嵌挿された軸芯をその連通孔に沿って他の孔部に案内することとしてもよい。これにより、軸芯を係止するネジ等を取り外すことなく、軸位置を他の孔部に移動させることが可能となる。   Moreover, it is good also as providing a communicating hole between said several hole parts, and guiding the shaft core inserted and inserted in one of the hole parts to another hole part along the communicating hole. As a result, the shaft position can be moved to another hole without removing a screw or the like for locking the shaft core.

さらに、一方の鋏片において枢着部に長い孔部を穿設し、この孔部に嵌挿させた軸芯を任意の位置で係止可能なものとすることにより、軸位置を調整可能としたものも例示できる。これにより、孔部の長さに対応した範囲内で、閉じ角を連続的に変化させ、任意の閉じ角を設定することが可能となる。ここで、長い孔部の形状は特に限定されず、長方形、長円形、湾曲したもの等が例示される。また、孔部を設ける方向も、鋏片の刃幅方向の成分を有すれば特に限定されないが、閉じ角の変化を大きくするためには、孔部の長手方向を刃幅方向と一致させることが効果的である。   Furthermore, by making a long hole in the pivot part in one of the collar pieces and making it possible to lock the shaft core fitted in this hole at any position, the axial position can be adjusted. It can also be illustrated. As a result, the closing angle can be continuously changed within a range corresponding to the length of the hole, and an arbitrary closing angle can be set. Here, the shape of the long hole is not particularly limited, and examples thereof include a rectangle, an oval, and a curved shape. Also, the direction in which the hole is provided is not particularly limited as long as it has a component in the blade width direction of the flange, but in order to increase the change in the closing angle, the longitudinal direction of the hole should be matched with the blade width direction. Is effective.

なお、孔部において軸芯位置を係止する手段としては、軸芯に螺合させるネジに、孔部の幅より広幅の頭部を有するネジを使用し、鋏片と軸芯とを締め付けて固定するもの、軸芯に螺合させるネジによる押さえの力が加わる面積をワッシャや板バネ等を介在させて孔部の幅より広くした上で固定するもの、孔部の内側面に配した止めネジ等で軸芯を固定するもの等を例示することができる。   As a means for locking the position of the shaft core in the hole, a screw having a head wider than the width of the hole is used as a screw to be screwed into the shaft core, and the collar piece and the shaft core are tightened. What is fixed, what is fixed after the area where the pressing force by the screw screwed into the shaft is applied is made wider than the width of the hole with a washer or leaf spring, etc., and a stopper arranged on the inner surface of the hole An example of fixing the shaft core with a screw or the like can be given.

従って、本発明によれば、軸位置調整手段を具備することにより、枢着部において一方の鋏片における軸芯の位置を、他方の鋏片に対して相対的に変化させることができる。これにより、鋏の使用者が閉じ角を調整することが可能となる。   Therefore, according to the present invention, by providing the shaft position adjusting means, the position of the shaft core in one hook piece can be changed relative to the other hook piece in the pivoting portion. As a result, the user of the bag can adjust the closing angle.

加えて、本発明に係る鋏は、「前記軸位置調整手段は、前記枢着部において一方の前記鋏片に穿設され、長手方向を前記鋏片の刃幅方向と一致させた長孔と、前記枢着部において他方の前記鋏片に穿設された円形孔と、該円形孔より径の小さな断面を有する円柱部、該円柱部の端部を前記円形孔より広径に拡径した軸芯端部、前記円柱部のもう一方の端部に形成され前記長孔に嵌挿された状態で前記長孔の内側面に当接して前記長手方向に摺動可能な角柱部、該角柱部に設けられた軸ネジ孔部を備える軸芯と、前記軸芯の前記軸ネジ孔部に螺合可能な軸ネジと、前記長孔の短手方向の一対の内側面から、夫々前記鋏片を貫通して設けられた一対の止めネジ孔部と、一対の該止めネジ孔部に夫々螺合可能に挿通され、その螺進及び螺退により前記長孔に嵌挿された前記角柱部の前記長孔における位置を調整可能な一対の止めネジと」を具備する構成とすることもできる。   In addition, the scissors according to the present invention have the following: “The shaft position adjusting means is formed in one of the scissors pieces in the pivot portion and has a long hole whose longitudinal direction coincides with the blade width direction of the scissors pieces. The circular hole drilled in the other flange piece in the pivotally attached portion, the cylindrical portion having a cross section having a smaller diameter than the circular hole, and the end of the cylindrical portion having a diameter larger than that of the circular hole. A prismatic column that is formed at the other end of the cylindrical portion and the axial end, and is slidable in the longitudinal direction in contact with the inner surface of the elongated hole while being fitted in the elongated hole. A shaft core provided with a shaft screw hole provided in a portion, a shaft screw that can be screwed into the shaft screw hole portion of the shaft core, and a pair of inner surfaces in the short direction of the long hole, respectively, A pair of set screw hole portions provided through the pieces and a pair of set screw hole portions that are threadably engageable with each other. It can also be configured to include a "and adjustable pair of set screw position in the slot of the prism portion which is inserted into the long hole.

ここで、軸芯の円柱部は、一方の鋏片の枢着部において穿設された円形孔よりその断面径が小さいため、この円形孔に挿通される。そして、円形孔の径より広径に形成された軸芯端部により、それ以上の侵入が防止される。これにより、軸芯は、円形孔に挿通された状態でこの円柱部において回転可能となり、一対の鋏片を回動自在とする回動中心となる。   Here, the cylindrical part of the shaft core has a smaller cross-sectional diameter than the circular hole drilled in the pivotal part of one of the flange pieces, and thus is inserted into the circular hole. Further, further intrusion is prevented by the end portion of the shaft core having a diameter larger than the diameter of the circular hole. As a result, the shaft core can be rotated in the cylindrical portion while being inserted into the circular hole, and becomes a rotation center that allows the pair of hook pieces to rotate.

また、軸芯の角柱部は、もう一方の鋏片に穿設された長孔に嵌挿された状態で長孔の内側面に当接してその長手方向に摺動可能とされるため、一対の側面の長さは長孔の短手方向の長さと略同一とされる。そして、もう一対の側面の長さは長孔の長手方向の長さより短く、その差が大きいほど軸芯位置を可変とする範囲が大きくなる。   In addition, since the prismatic part of the shaft core is slidable in the longitudinal direction while being in contact with the inner surface of the long hole while being fitted in the long hole formed in the other flange, The length of the side surface is substantially the same as the length of the long hole in the short direction. The length of the other pair of side surfaces is shorter than the length of the long hole in the longitudinal direction, and the larger the difference, the larger the range in which the axial center position can be varied.

さらに、長孔は、その長手方向が鋏片の刃幅方向と一致している。ここで、長孔の形状は、その内側面に軸芯の角柱部を当接させ摺動させるため、長手方向の一対の内側面が平行であれば特に限定されず、矩形や端部を円形に湾曲させて形成された形状が例示される。   Furthermore, the longitudinal direction of the long hole coincides with the blade width direction of the flange. Here, the shape of the long hole is not particularly limited as long as the pair of inner side surfaces in the longitudinal direction are parallel because the prismatic portion of the shaft core is brought into contact with and slides on the inner side surface, and the rectangular shape and the end portion are circular. The shape formed by curving is illustrated.

また、軸ネジは角柱部に設けらた軸ネジ孔部と螺合することにより、一方の鋏片にその円柱部を挿通し、他方の鋏片の長孔にその角柱部に嵌挿させた軸芯を係止し、一対の鋏片を互いに枢着させる。ここで、軸ネジの種類は特に限定されないが、ネジのヘッド部が鋏片から大きく突出することがなく、髪が引掛かったり絡まったりしにくい形状であることが望ましい。   Further, the shaft screw is screwed into a shaft screw hole provided in the prismatic part, so that the cylindrical part is inserted into one collar piece, and the prismatic part is fitted into the elongated hole of the other collar piece. The shaft core is locked and the pair of hooks are pivotally attached to each other. Here, the type of the shaft screw is not particularly limited, but it is desirable that the head portion of the screw does not protrude greatly from the collar piece and the hair is not easily caught or tangled.

さらに、止めネジ孔部は、長孔の短手方向の一対の内側面に設けられ、夫々刃幅方向に鋏片を貫通している。これにより、止めネジ孔部に挿通した止めネジを、枢着部において鋏片の外部の側面から調整することが可能となる。   Furthermore, the set screw hole portion is provided on a pair of inner side surfaces in the short direction of the long hole, and penetrates the flange piece in the blade width direction, respectively. Thereby, the set screw inserted through the set screw hole can be adjusted from the outside side surface of the collar piece at the pivotally attached portion.

また、止めネジは、拡径した頭部を有しない棒状又は筒状のピン型ネジを使用することができる。一般的に、先端の形状には、平先、棒先、丸先、尖り先等があるが、角柱部の側面に当接してその位置を調整するため、平面との当接状態が安定する平先や棒先ものが好適である。ここで、止めネジの螺進及び螺退は、棒状の止めネジの頭部のすり割部分をドライバーで回して行ったり、筒状の止めネジの六角孔を六角レンチで回して行うこともできる。また、止めネジの先端に竜頭を取付けて鋏片の外部に延出させ、その竜頭を回すことにより止めネジを螺進及び螺退させるものとすれば、鋏の使用者が工具を使用することなく、軸位置の調整、すなわち閉じ角の調整を行うことができる。   The set screw can be a rod-shaped or cylindrical pin-type screw that does not have an enlarged head. In general, the tip has a flat tip, rod tip, round tip, pointed tip, etc., but because it abuts on the side surface of the prism and adjusts its position, the contact state with the flat surface is stable. A flat tip or a rod tip is preferred. Here, the screwing and unscrewing of the set screw can be performed by turning the slit part of the head of the rod-like set screw with a screwdriver or by turning the hexagon hole of the cylindrical set screw with a hexagon wrench. . Also, if the crown is attached to the tip of the set screw and extended to the outside of the rod, and the set screw is screwed and unscrewed by turning the crown, the user of the kite should use the tool. Without adjustment, the shaft position can be adjusted, that is, the closing angle can be adjusted.

なお、角柱部の位置の固定は、かかる止めネジを使用しなくとも、角柱部の軸ネジ孔部と螺合する軸ネジにより、軸芯と鋏片を締付けて係止することによっても可能ではあるが、軸ネジとは別個の止めネジを使用することにより、軸ネジを外さなくても軸芯の位置を調整することが可能となる。また、軸ネジは軸芯位置の調整とは無関係となるため、軸ネジにより枢着部の締付け具合の調整をすることも可能となる。   Note that the position of the prism portion can be fixed by tightening and locking the shaft core and the flange with the shaft screw that is screwed into the shaft screw hole portion of the prism portion without using such a set screw. However, by using a set screw separate from the shaft screw, the position of the shaft core can be adjusted without removing the shaft screw. Further, since the shaft screw has no relation to the adjustment of the shaft center position, it is possible to adjust the tightening degree of the pivotally attached portion by the shaft screw.

従って、本発明によれば、一方の鋏片に穿設された円形孔に挿通させた軸芯に形成された角柱部を、他方の鋏片に穿設された長孔に嵌挿させ、長孔にそって摺動させることにより、一対の鋏片の間で軸芯の位置を相対的に変化させることができる。これにより閉じ角を変化させ調整することが可能となる。また、長孔は長手方向を鋏片の刃幅方向と一致させて形成されているため、軸芯位置の変化により効果的に閉じ角が変化する。   Therefore, according to the present invention, the rectangular column formed in the shaft core inserted through the circular hole drilled in one collar piece is fitted into the long hole drilled in the other collar piece, By sliding along the hole, the position of the shaft core can be relatively changed between the pair of flanges. As a result, the closing angle can be changed and adjusted. Moreover, since the long hole is formed so that the longitudinal direction coincides with the blade width direction of the scissors, the closing angle is effectively changed by changing the axial position.

さらに、長孔における角柱部の位置は、一対の止めネジの螺進及び螺退により任意の位置で固定することができるため、角柱部が長孔において摺動可能な長さに相応する範囲内で、閉じ角を連続的に変化させて任意の閉じ角を設定し、また、微調整することが可能となる。   Further, the position of the prism portion in the long hole can be fixed at an arbitrary position by screwing and unscrewing of the pair of set screws. Thus, the closing angle can be continuously changed to set an arbitrary closing angle and fine adjustment can be performed.

加えて、長孔における角柱部の位置の調整を、止めネジを使用して行うため、軸ネジを外すことなく軸位置を変化させ、閉じ角を調整することが可能となる。   In addition, since the position of the prismatic part in the long hole is adjusted using a set screw, it is possible to adjust the closing angle by changing the shaft position without removing the shaft screw.

以上のように、本発明の鋏によれば、美容師等の鋏の使用者が、自ら、閉じ角を変化させ調整することが可能となる。   As described above, according to the bag of the present invention, the user of the bag such as a beautician can change and adjust the closing angle by himself.

以下、本発明の実施するための最良の一実施形態である鋏について、図1乃至図4に基づき説明する。図1(a)は本発明の鋏の一例を示す全体図であり、図1(b)は要部を拡大して示す拡大図であり、図2は図1の鋏の分解斜視図であり、図3及び図4は図1の鋏の軸芯の位置の変化に対応した閉じ角の変化を示す説明図である。   Hereinafter, a kite which is the best embodiment for carrying out the present invention will be described with reference to FIGS. FIG. 1A is an overall view showing an example of the bag of the present invention, FIG. 1B is an enlarged view showing an essential part, and FIG. 2 is an exploded perspective view of the bag of FIG. FIGS. 3 and 4 are explanatory views showing changes in the closing angle corresponding to changes in the position of the shaft core of the heel shown in FIG.

本実施形態の鋏1は、夫々刃部2a,2b及び持部3a,3bを有する一対の鋏片4a,4bと、刃部2a,2bと持部3a,3bとの間に位置し、一対の鋏片4a,4bを軸芯11周りに互いに回動可能に枢着する枢着部5とを主に具備して構成されている。   The scissors 1 of this embodiment are positioned between a pair of scissors pieces 4a and 4b having blade portions 2a and 2b and holding portions 3a and 3b, and between the blade portions 2a and 2b and the holding portions 3a and 3b, respectively. The pivot piece 4a, 4b is mainly provided with a pivoting portion 5 pivotally pivoted around the shaft core 11.

そして、枢着部5において一方の鋏片4aに穿設され、長手方向を鋏片4aの刃幅方向と一致させた矩形の長孔20と、枢着部5において他方の鋏片4bに穿設された円形孔10と、軸芯11と、軸芯11に螺合可能な軸ネジ30と、長孔20の内側面に設けられた一対の止めネジ孔部21a,21bと、これらの止めネジ孔部21a,21bに螺合可能な一対の止めネジ22a,22bとにより、本発明における閉じ角調整手段(軸位置調整手段)が構成されている。   Then, a rectangular long hole 20 is formed in one of the collar pieces 4a in the pivot portion 5 and the longitudinal direction thereof coincides with the blade width direction of the collar piece 4a, and the other collar piece 4b in the pivot portion 5 is drilled. The circular hole 10 provided, the shaft core 11, the shaft screw 30 that can be screwed to the shaft core 11, a pair of set screw hole portions 21a and 21b provided on the inner surface of the long hole 20, and these locks The pair of set screws 22a and 22b that can be screwed into the screw holes 21a and 21b constitute a closing angle adjusting means (axial position adjusting means) in the present invention.

更に詳しく説明すると、軸芯11は、円柱部12、円柱部12の端部に設けられた軸芯端部13、円柱部12のもう一方の端部に形成された角柱部15、角柱部15に設けられた軸ネジ孔部16を具備している。   More specifically, the shaft core 11 includes a column portion 12, a shaft end portion 13 provided at the end portion of the column portion 12, a prismatic portion 15 formed at the other end portion of the columnar portion 12, and a prismatic portion 15. A shaft screw hole portion 16 is provided.

ここで、軸芯11の円柱部12は、その断面径が鋏片4bの枢着部5において穿設された円形孔10より小さいものとされ、円形孔10に挿通可能である。そして、円形孔10の径より広径に形成された軸芯端部13により、それ以上の侵入が防止される。これにより、軸芯11は、この円柱部12において回転可能となり、一対の鋏片4a,4bを回動自在とする回動中心となる。   Here, the cylindrical portion 12 of the shaft core 11 has a smaller cross-sectional diameter than the circular hole 10 drilled in the pivoting portion 5 of the collar piece 4 b, and can be inserted into the circular hole 10. Further, further intrusion is prevented by the shaft end portion 13 formed to have a diameter wider than the diameter of the circular hole 10. Thereby, the shaft core 11 becomes rotatable at the cylindrical portion 12, and becomes a rotation center that allows the pair of flange pieces 4a and 4b to rotate freely.

また、長孔20は、その長手方向が鋏片4aの刃幅方向と一致する矩形に形成されている。そして、軸芯11の角柱部15は、その一対の側面の長さは長孔20の短手方向の長さと略同一とされ、もう一対の側面の長さは長孔20の長手方向の長さより短いものとされている。これにより、軸芯11の角柱部15は長孔20に嵌挿された状態で、その側面を長孔20の内側面に当接して長手方向に摺動可能となる。   Moreover, the long hole 20 is formed in the rectangle in which the longitudinal direction corresponds with the blade width direction of the collar piece 4a. The length of the pair of side surfaces of the prism portion 15 of the shaft 11 is substantially the same as the length of the long hole 20 in the short direction, and the length of the other pair of side surfaces is the length of the long hole 20 in the long direction. It is supposed to be shorter. As a result, the prismatic portion 15 of the shaft core 11 is slidable in the longitudinal direction with the side surface abutting against the inner surface of the long hole 20 in a state of being fitted into the long hole 20.

また、本実施例では、軸芯11の円柱部12の直径と角柱部15の対角線の長さは略同一とされ、円柱部12及び角柱部15の高さは、夫々鋏片4a,4bの厚さよりも小さく設定されている。そのため、軸芯11を一対の鋏片4a,4bに取付けた状態で、角柱部15側の端部が鋏片4aから突出することがない。これにより、軸ネジ30を角柱部15に設けられた軸ネジ孔16に螺合させた状態で、軸ネジ30の頭部と鋏片4aとの間に余分な隙間を生じることがなく、枢着部5のがたつきを防止することができる。   In the present embodiment, the diameter of the cylindrical portion 12 of the shaft core 11 and the length of the diagonal line of the rectangular column portion 15 are substantially the same, and the height of the cylindrical portion 12 and the rectangular column portion 15 are the heights of the flange pieces 4a and 4b, respectively. It is set smaller than the thickness. Therefore, in the state where the shaft core 11 is attached to the pair of flange pieces 4a and 4b, the end on the prismatic portion 15 side does not protrude from the flange piece 4a. As a result, in the state in which the shaft screw 30 is screwed into the shaft screw hole 16 provided in the prism portion 15, no extra gap is generated between the head of the shaft screw 30 and the flange 4a. The rattling of the wearing part 5 can be prevented.

次に、軸ネジ30は、半球を平たくした形状のヘッド部を有する小ネジで、角柱部15に設けらた軸ネジ孔部16と螺合する。これにより、鋏片4bの円形孔10にその円柱部12を挿通し、他方の鋏片4aの長孔20にその角柱部15に嵌挿させたを軸芯11を係止し、一対の鋏片4a,4bを互いに枢着させる。   Next, the shaft screw 30 is a small screw having a head portion with a flattened hemisphere, and is screwed into the shaft screw hole portion 16 provided in the prism portion 15. Thus, the cylindrical portion 12 is inserted into the circular hole 10 of the flange piece 4b, and the shaft core 11 is inserted into the elongated hole 20 of the other flange piece 4a and is inserted into the rectangular column portion 15 to lock the pair of flanges. The pieces 4a and 4b are pivotally attached to each other.

また、止めネジは、一対の六角孔付き止めネジ22a,22bが使用され、これに螺合する止めネジ孔部21a,21bは、長孔20の短手方向の一対の内側面の夫々の略中央に設けられている。これにより、止めネジ22a,22bを夫々止めネジ孔部21a,21bに挿通し、一方を螺進させ他方を螺退させることにより、長孔20に嵌挿された角柱部15の位置を調整し固定することができる。そして、止めネジ孔部21a,21bは夫々刃幅方向に鋏片4aを貫通しているため、枢着部5において、鋏片4aの外部の側面から止めネジ22a,22bを調整することが可能となる。このとき、止めネジ22a,22bの外側の先端に竜頭を取付けて鋏片4aの外部に延出させ、鋏の使用者が工具を使用することなく、その竜頭を回すことにより軸位置の調整、すなわち閉じ角の調整を行うものとすることができる。   Further, as the set screw, a pair of set screws 22a and 22b with hexagonal holes are used, and the set screw hole portions 21a and 21b screwed to the set screws are respectively abbreviated on the pair of inner side surfaces in the short direction of the long hole 20. It is provided in the center. Accordingly, the position of the prism portion 15 inserted into the elongated hole 20 is adjusted by inserting the set screws 22a and 22b into the set screw hole portions 21a and 21b, respectively, screwing one and screwing the other. Can be fixed. And since the set screw hole parts 21a and 21b have penetrated the collar piece 4a in the blade width direction, respectively, it is possible to adjust the set screws 22a and 22b from the side surface outside the collar piece 4a in the pivoting part 5. It becomes. At this time, the crown is attached to the outer ends of the set screws 22a and 22b and extended to the outside of the rod piece 4a, and the shaft user can adjust the axial position by turning the crown without using a tool. That is, the closing angle can be adjusted.

次に、本実施形態の鋏1における軸位置の調整方法、すなわち、閉じ角の調整方法について説明する。まず、図1(b)に示すように、軸芯11の角柱部15の中心を長孔20の中心Cに位置させて固定すれば、軸芯11がいずれの鋏片4a,4bにおいても中央にあり、通常の鋏と同様の状態で使用することができる。なお、図1(b)では、長孔20内での角柱部15の位置を明示するため、軸ネジ30を省略して図示している。   Next, a method for adjusting the shaft position in the heel 1 of the present embodiment, that is, a method for adjusting the closing angle will be described. First, as shown in FIG. 1B, if the center of the prism portion 15 of the shaft core 11 is positioned and fixed at the center C of the long hole 20, the shaft core 11 is centered in any of the flange pieces 4a and 4b. It can be used in the same state as a normal bag. In FIG. 1B, the shaft screw 30 is omitted in order to clearly show the position of the prism portion 15 in the long hole 20.

そして、図3に示すように、閉じ角を大きくしたいとき、すなわち、髪をより逃がしやすくして切断したい場合は、軸芯11の角柱部15を長孔20において鋏を使用する手の親指側の側面20aに向かって摺動させる。このとき、角柱部15が側面20aに当接したとき、軸位置はAとなり、閉じ角が最大となる。ここで、図3においては、軸が長孔20の中央Cに位置する場合の鋏片4aを二点鎖線で示し、軸が中央Cにある場合と、軸位置をAに変化させた場合とで、一対の鋏片4a,4bが噛合う状態を、鋏片4b側の位置を任意の位置Xに固定して比較し、軸の位置をCからAに移動させたことにより閉じ角がθから拡大した様子を図示している。なお、図3では、角柱部15の位置を明示するため、軸ネジ30を省略して図示している。   As shown in FIG. 3, when it is desired to increase the closing angle, that is, when it is desired to cut the hair more easily, the prism 15 of the shaft core 11 is placed on the thumb side of the hand using the heel in the long hole 20. Slide toward the side surface 20a. At this time, when the prism portion 15 is in contact with the side surface 20a, the axial position is A, and the closing angle is maximum. Here, in FIG. 3, when the axis is located at the center C of the long hole 20, the flange 4 a is indicated by a two-dot chain line, and when the axis is at the center C and when the axis position is changed to A Then, the state in which the pair of collar pieces 4a and 4b are engaged is compared with the position on the collar piece 4b side fixed at an arbitrary position X, and the closing angle becomes θ by moving the shaft position from C to A. The state of being enlarged from is shown. In FIG. 3, the shaft screw 30 is omitted to clearly show the position of the prism portion 15.

更に、図4に示すように、閉じ角を小さくしたいとき、すなわち、髪を逃がさずに切断したい場合は、軸芯11の角柱部15を長孔20において鋏を使用する手の小指側の側面20bに向かって摺動させる。このとき、角柱部15が側面20bに当接したとき、軸位置はBとなり、閉じ角が最小となる。ここで、図4においては、図3と同様に、軸が長孔20の中央Cに位置する場合の鋏片4aを二点鎖線で示し、軸が中央Cにある場合と、軸位置をBに変化させた場合とで、一対の鋏片4a,4bが噛合う状態を、鋏片4b側の位置を位置Xに固定して比較し、軸の位置をCからBに移動させたことにより、閉じ角がθから減少した様子を図示している。なお、図4においても、軸ネジ30を省略して図示している。   Furthermore, as shown in FIG. 4, when it is desired to reduce the closing angle, that is, when the hair is to be cut without escaping, the side of the little finger side of the hand that uses the heel in the long hole 20 is formed in the rectangular column portion 15 of the shaft 11. Slide toward 20b. At this time, when the prism portion 15 is in contact with the side surface 20b, the axial position is B, and the closing angle is minimum. Here, in FIG. 4, similarly to FIG. 3, the flange 4 a when the shaft is located at the center C of the long hole 20 is indicated by a two-dot chain line, and when the shaft is located at the center C, the shaft position is represented by B The state in which the pair of hook pieces 4a and 4b are engaged with each other is compared with the position of the hook piece 4b side fixed at the position X, and the shaft position is moved from C to B. The state in which the closing angle is decreased from θ is illustrated. In FIG. 4, the shaft screw 30 is omitted.

以上のように、鋏片4aの刃部2aの任意の位置Xにおいて、閉じ角が最大値及び最小値となる場合を示したが、止めネジ22a,22bによる軸芯11位置の微調整により、この範囲内で任意の閉じ角を設定することが可能となる。   As described above, the case where the closing angle becomes the maximum value and the minimum value at the arbitrary position X of the blade portion 2a of the flange piece 4a has been shown. By fine adjustment of the position of the shaft core 11 by the set screws 22a and 22b, An arbitrary closing angle can be set within this range.

また、鋏の使用者が上記のように閉じ角を調整し、髪の逃がしやすさの設定を所望のものとしても、刃部が摩耗すると刃が髪を捕えにくくなり、同じ閉じ角でも髪が逃げ易くなってしまう。この場合は、上記の同様の操作により閉じ角を微調整することにより、髪の逃げやすさについての所望の設定を維持することができる。   In addition, even if the user of the heel adjusts the closing angle as described above and sets the desired ease of hair release, the blade becomes difficult to catch the hair when the blade wears, and even at the same closing angle Easier to escape. In this case, it is possible to maintain a desired setting for the ease of hair escape by finely adjusting the closing angle by the same operation as described above.

なお、本実施形態では、刃部2a,2bとして、刃幅をアールを付けて変化させた刃(笹刃)を使用しているが、刃幅が刃元から刃先にかけて直線的に減少する通常の鋏においても、上記と同様に、軸位置の変化により閉じ角を変化させることができる。   In this embodiment, the blades 2a and 2b use blades (blade blades) whose blade widths are changed with rounded corners, but the blade widths generally decrease linearly from the blade base to the blade tip. As in the case described above, the closing angle can be changed by changing the axial position.

以上のように、本実施形態の鋏1によれば、一方の鋏片に穿設された円形孔10に挿通させた軸芯11に形成された角柱部15を、他方の鋏片に穿設された長孔20に嵌挿させ、長孔20にそって摺動させることにより、一対の鋏片4a,4bの間で軸芯11の位置を相対的に変化させることができる。これにより、閉じ角を変化させ調整することが可能となる。また、長孔20は長手方向を鋏片の刃幅方向と一致させて形成されているため、軸芯11の位置の変化により効果的に閉じ角が変化する。   As described above, according to the collar 1 of this embodiment, the prism portion 15 formed in the shaft core 11 inserted through the circular hole 10 formed in one collar piece is drilled in the other collar piece. The position of the shaft core 11 can be relatively changed between the pair of flanges 4a and 4b by being inserted into the elongated holes 20 and sliding along the elongated holes 20. As a result, the closing angle can be changed and adjusted. Moreover, since the long hole 20 is formed so that the longitudinal direction coincides with the blade width direction of the flange, the closing angle is effectively changed by the change in the position of the shaft core 11.

さらに、長孔20における角柱部15の位置は、一対の止めネジ22a,22bの螺進及び螺退により任意の位置で固定することができるため、角柱部15の摺動可能な長さに相応する範囲内で閉じ角を連続的に変化させ、微調整することが可能となる。   Further, the position of the prism portion 15 in the long hole 20 can be fixed at an arbitrary position by screwing and unscrewing of the pair of set screws 22a and 22b, and therefore corresponds to the slidable length of the prism portion 15. It is possible to make fine adjustment by continuously changing the closing angle within the range.

これにより、美容師等の鋏の使用者が、鋏の閉じ角を自ら変化させることができ、髪を逃がし難くして切断することも、敢えて髪を逃がし易くして切断することも可能となる。そして、閉じ角を微調整しながら所望の設定として鋏を使用することにより、毛先の処理を微妙に変化させた多様な髪形を表現することが可能となる。   This makes it possible for a user of a beard, such as a hairdresser, to change the closing angle of the beard, making it difficult for hair to escape, or to dare to make hair easy to escape. . Then, by using the wrinkle as a desired setting while finely adjusting the closing angle, it is possible to express various hairstyles with subtle changes in the processing of the hair ends.

加えて、鋏の使用により刃が摩耗した場合においても、鋏の使用者が自ら閉じ角を調整し、髪の逃げ易さについての所望の設定を維持することが可能となる。   In addition, even when the blade is worn due to the use of the heel, the heel user can adjust the closing angle by himself and maintain a desired setting for the ease of hair escape.

以上、本発明について好適な実施形態を挙げて説明したが、本発明はこの実施形態に限定されるものではなく、以下に示すように、本発明の趣旨を逸脱しない範囲において、種々の改良及び設計の変更が可能である。   The present invention has been described with reference to a preferred embodiment. However, the present invention is not limited to this embodiment, and various improvements and modifications can be made without departing from the spirit of the present invention as described below. Design changes are possible.

例えば、本実施例では、円形孔は動刃に穿設され、長孔は静刃に穿設された場合を示したが、これに限定されず逆の関係であってもよく、静刃において軸芯を固定し、動刃に対して軸芯の位置を変化させるものとすることもできる。   For example, in the present embodiment, the case where the circular hole is drilled in the moving blade and the long hole is drilled in the stationary blade is shown, but the present invention is not limited to this, and the reverse relationship may be used. It is also possible to fix the shaft core and change the position of the shaft core with respect to the moving blade.

また、本実施形態では、長孔は矩形形状とされているが、長手方向の一対の内側面が平行であればこの形状に限定されず、例えば、端部が円形に湾曲したものとすることもできる。   In this embodiment, the long hole is rectangular, but the shape is not limited to this shape as long as the pair of inner side surfaces in the longitudinal direction are parallel. For example, the end is assumed to be circularly curved. You can also.

更に、円柱部の径と角柱部の対角線の長さとの関係、及び両者の高さと鋏片の厚さの関係は、本実施例のものに限定されず、円柱部及び角柱部が共に円形孔に挿通でき、軸芯の角柱部側の端部が長孔を設けた鋏片から突出しない範囲で設定可能である。例えば、円柱部の径に比べて角柱部が小さく形成され、これに対応して長孔の短手方向の長さを短いものとしてもよく、また、円柱部の高さを鋏片の厚さよりも大きなものとし、角柱部と共に長孔に嵌挿されるものとすることもできる。   Furthermore, the relationship between the diameter of the cylindrical portion and the length of the diagonal line of the prism portion, and the relationship between the height and the thickness of the flange are not limited to those of the present embodiment, and both the cylindrical portion and the prism portion are circular holes. The end of the shaft core on the side of the prism portion can be set within a range in which it does not protrude from the flange piece provided with the long hole. For example, the prismatic part is formed smaller than the diameter of the cylindrical part, and the length of the long hole in the short direction may be shortened correspondingly, and the height of the cylindrical part may be less than the thickness of the flange. It can also be made large and can be inserted into the elongated hole together with the prism portion.
