Description

本発明は、枢軸部に特徴のある理美容鋏に関し、詳細には、枢軸部の締め付け具合の微調整を精度良く行え、枢軸部が出っ張りが少なく嵩高くない理美容鋏に関する。 The present invention relates to hairdressing scissors with a distinctive pivot, and more specifically to hairdressing scissors in which the tightness of the pivot can be precisely adjusted and the pivot does not protrude much and is not bulky.

理美容鋏は、一対の刃体の頻回な開閉により枢軸部の締め付けが緩むことがあるため、締め付け具合を調整し、刃体間の噛合圧力を調整することや使用者の好みの噛合圧力に調整することがある。また、枢軸部が出っ張りが多く嵩高いと理美容鋏を操作する上でバランスが悪くなり、使い勝手が悪くなることがある。 When a pair of hairdressing scissors' blades are frequently opened and closed, the tightness of the pivot can loosen, so the tightness can be adjusted to adjust the meshing pressure between the blades or to the user's preferred meshing pressure. Also, if the pivot protrudes too much and is bulky, the balance of the hairdressing scissors can be poor, making them difficult to use.

従来、枢軸部の締め付け具合を微調整できるように工夫された考案の提案がある。すなわち、特許文献１には、刃部と持手部を有し、支軸周りに回動可能な第一鋏片及び第二鋏片と、第一鋏片の支軸近傍の第二鋏片と対向する面に形成された深さが刃部側から持手部側に向かって浅くなる凹部と、凹部に嵌挿可能に形成された嵌挿体とを具備する鋏が開示されている。
また、枢軸部が出っ張りが少なく嵩高くなく、使用者の邪魔にならないように工夫された発明の提案がある。すなわち、特許文献に２は、各刃体の各貫通孔に少なくとも軸部と円板部が一体加工された軸部材の軸部と他の軸部材の軸部とが互いに対向するように嵌挿され、螺合連結された状態で、一体加工された軸部材に外装されたコイルバネの付勢力により両刃体を他の軸部材との間で挟み込み、一体加工された軸部材の一部を薄くすることができる鋏の枢軸構造が開示されている。 Conventionally, there have been proposals for devices that allow fine adjustment of the tightness of the pivot part. That is, Patent Document 1 discloses scissors that have a blade part and a handle part, a first scissor piece and a second scissor piece that can rotate around a support shaft, a recess that is formed on the surface of the first scissor piece near the support shaft and that faces the second scissor piece and that has a depth that becomes shallower from the blade part side toward the handle part side, and an insert that is formed so that it can be inserted into the recess.
Also, there is a proposal for an invention in which the pivot portion is designed to have little protrusion and is not bulky so as not to get in the way of the user. That is, Patent Document 2 discloses a pivot structure for scissors in which the shaft portion of a shaft member having at least a shaft portion and a disk portion integrally machined with each other is inserted into each through-hole of each blade body so that the shaft portion of another shaft member faces each other, and in a state in which they are screwed together, both blade bodies are sandwiched between the other shaft member by the biasing force of a coil spring exteriorly mounted on the integrally machined shaft member, and a part of the integrally machined shaft member can be made thin.

しかし、特許文献１の考案は、一対の刃体の接触圧力（噛合圧力）の微調整を厚みの異なる嵌挿片（嵌挿体）を使い分けて行うため作業が繁雑であり、また、鋏の構成が複雑となる。特許文献２の発明は、刃体の表面から飛び出す部分の量が減る枢軸構造ではあるが、軸部材にコイルバネが外装される構成であるため、出っ張りを少なくし嵩高さを抑えることに限界がある。 However, the invention of Patent Document 1 requires fine adjustment of the contact pressure (interlocking pressure) of a pair of blades by using inserts (inserts) of different thicknesses, which makes the work complicated and the structure of the scissors complex. The invention of Patent Document 2 has a pivot structure that reduces the amount of the part that protrudes from the surface of the blades, but because the coil spring is attached to the shaft member, there is a limit to how much it can reduce protrusion and bulk.

本発明は、上記の事情に鑑みなされたもので、枢軸部の締め付け具合の微調整が容易に行える理美容鋏を提供することを課題とする。また、枢軸部が出っ張りが少なく嵩高くない、使い勝手の良い理美容鋏を提供することを課題とする。 The present invention has been made in consideration of the above circumstances, and aims to provide hairdressing scissors that allow easy fine adjustment of the tightness of the pivot. It also aims to provide hairdressing scissors that are easy to use, with a pivot that does not protrude much and is not bulky.

上記の課題を解決する本発明は、第１刃体と第２刃体が枢軸部で枢着され、第１刃体の基端と第２刃体の基端にそれぞれ設けられる把持部を操作することにより第１刃体と第２刃体が開閉自在な理美容鋏であって、前記枢軸部は、前記第１刃体と前記第２刃体に挿通される、フランジを有する頭部とくびれ箇所を有する軸部とからなる軸体と、当該軸体に嵌着される転がり軸受と、当該転がり軸受を前記軸部のくびれ箇所に固着する止め輪と、前記第２刃体で前記軸部に螺着される締結体と、前記頭部のフランジの径より拡径の孔を有し、前記第１刃体の表側に固着され、前記第１刃体の前記軸体からの離脱を防ぐ止め体と、を備え、前記軸体における頭部のフランジの表側に、治具を嵌めて軸体を微妙に回すための凹部が形成され、前記転がり軸受の径は、前記頭部のフランジの径より拡径されていることを特徴とする理美容鋏に関する。この構成により、第１刃体と枢軸部が一体となり、軸体の頭部を左右に回すことにより第１刃体を動かし、第１刃体と第２刃体の間隔を調整することができる。 The present invention, which solves the above-mentioned problems, relates to hairdressing scissors in which a first blade body and a second blade body are pivotally connected by a pivot shaft, and the first blade body and the second blade body can be opened and closed by operating grips provided at the base end of the first blade body and the base end of the second blade body, respectively, the pivot shaft comprising: a shaft body which is inserted through the first blade body and the second blade body and which comprises a head with a flange and a shaft portion having a narrowed portion , a rolling bearing fitted onto the shaft body, a retaining ring which secures the rolling bearing to the narrowed portion of the shaft portion , a fastener which is screwed onto the shaft portion by the second blade body, and a stopper which has a hole with a larger diameter than the diameter of the flange of the head and is fixed to the front side of the first blade body and prevents the first blade body from coming off the shaft body, wherein a recess is formed on the front side of the flange of the head of the shaft body for fitting a jig to finely rotate the shaft body, and the diameter of the rolling bearing is larger than the diameter of the flange of the head. With this configuration, the first blade body and the pivot portion are integrated, and the first blade body can be moved by rotating the head of the shaft body left and right, thereby adjusting the distance between the first blade body and the second blade body.

上記の発明において、第２刃体に軸体の軸部と螺合する雌ねじを螺刻してもよい。この構成により、第２刃体を強固に締結できる。 In the above invention, the second blade may be threaded with a female thread that screws into the shaft portion of the shaft body. This configuration allows the second blade to be firmly fastened.

本発明によれば、枢軸部が簡単な構成でありながら、一対の刃体の間隔の微調整、ひいては刃体間の噛合圧力の微調整を精度良く行うことができるので、頻回な使用により緩んだ枢軸部の締め付け具合を精度良く微調整でき、また、使用者の好みに応じた刃体間の噛合圧力に微調整することが可能な理美容鋏を提供できる。
また、一対の刃体の間隔を適度に設定することにより触点が不要な構成とできるので、刃体の開閉を円滑に行える使い勝手に優れる理美容鋏を提供できる。 According to the present invention, although the pivot portion has a simple configuration, it is possible to precisely adjust the distance between a pair of blade bodies, and therefore the meshing pressure between the blade bodies. This makes it possible to precisely adjust the tightness of the pivot portion that has become loose due to frequent use, and also to provide hairdressing scissors that can be precisely adjusted to the meshing pressure between the blade bodies according to the user's preference.
Furthermore, by appropriately setting the distance between the pair of blades, a configuration that does not require contact can be achieved, providing a pair of hairdressing scissors that are easy to use and allow the blades to be opened and closed smoothly.

本発明によれば、枢軸部が出っ張りが少なく、嵩高くないので、操作する上でバランスが良く、使い勝手に優れる理美容鋏を提供できる。 The present invention provides hairdressing scissors that are well-balanced and easy to use because the pivot portion does not protrude much and is not bulky.

本発明によれば、分解・組立が容易で、刃研ぎなどのメンテナンスを円滑に行える理美容鋏を提供できる。 The present invention provides hairdressing scissors that are easy to disassemble and assemble, and allow for smooth maintenance such as blade sharpening.

本実施形態に係る理美容鋏１００は、図１に示すように、第１刃体６０、第２刃体７０、把持部６５、７５及び枢軸部９０から構成されている。 As shown in FIG. 1, the hairdressing scissors 100 according to this embodiment are composed of a first blade 60, a second blade 70, gripping portions 65 and 75, and a pivot portion 90.

本実施形態に係る理美容鋏１００の枢軸部９０を構成する軸体１０は、図３に示すように、フランジ１５を有する頭部１１と軸部１２とから構成されている。軸部１２は略中央にくびれ箇所１３が形成され、当該くびれ箇所１３から下に雄ねじが螺刻されている。頭部１１のフランジ１５の表側には、図１０に示す治具８０を嵌めて軸体１０を回すための凹部１４が形成されている。 As shown in FIG. 3, the shaft 10 constituting the pivot 90 of the hairdressing scissors 100 according to this embodiment is made up of a head 11 having a flange 15 and a shaft 12. A narrowed portion 13 is formed in the approximate center of the shaft 12, and a male thread is threaded downward from the narrowed portion 13. A recess 14 is formed on the front side of the flange 15 of the head 11 into which a jig 80 shown in FIG. 10 is fitted to rotate the shaft 10.

本実施形態に係る理美容鋏１００の枢軸部９０を構成する転がり軸受２０は、図４に示すように、インナーレース２１とアウターレース２２間に玉が転動体として介在する玉軸受けである。転がり軸受２０の上下方向の一方にフランジ２３が形成されている。フランジ２３の径は、軸体１０における頭部１１のフランジ１５の径より拡径されている。また、転がり軸受２０は、フランジ２３を設けず、転がり軸受２０の径自体を頭部１１のフランジ１５の径より拡径に形成してもよい。さらに、転がり軸受２０は、玉軸受けに限定されす、他の転がり軸受でもよい。 The rolling bearing 20 constituting the pivot portion 90 of the hairdressing scissors 100 according to this embodiment is a ball bearing in which balls are interposed as rolling elements between an inner race 21 and an outer race 22, as shown in FIG. 4. A flange 23 is formed on one side of the rolling bearing 20 in the vertical direction. The diameter of the flange 23 is larger than the diameter of the flange 15 of the head 11 in the shaft body 10. The rolling bearing 20 may also be formed so that the diameter of the rolling bearing 20 itself is larger than the diameter of the flange 15 of the head 11 without providing the flange 23. Furthermore, the rolling bearing 20 is not limited to a ball bearing, and may be another rolling bearing.

本実施形態に係る理美容鋏１００の枢軸部９０を構成する図５に示すＥ－リング３０は、固着手段に相当する。固着手段は、Ｅ－リングに限定されず、Ｃ－リングのような他の止め輪でもよく、また金属用接着剤等でもよい。 The E-ring 30 shown in FIG. 5, which constitutes the pivot portion 90 of the hairdressing scissors 100 according to this embodiment, corresponds to the fastening means. The fastening means is not limited to an E-ring, but may be another type of retaining ring such as a C-ring, or may be a metal adhesive, etc.

本実施形態に係る理美容鋏１００の枢軸部９０を構成する締結体４０は、図６に示すように、リング状をなし、中央に孔４１を有する。孔４１の内周には、軸体１０の軸部１２の雄ネジと螺合する雌ネジが螺刻されている。締結体４０の表側には、治具８０を嵌めて締結体４０を回すために用いる凹部４２が形成されている。 The fastener 40 constituting the pivot 90 of the hairdressing scissors 100 according to this embodiment is ring-shaped and has a hole 41 in the center, as shown in FIG. 6. A female thread is threaded on the inner circumference of the hole 41 to be engaged with the male thread of the shaft 12 of the shaft body 10. A recess 42 is formed on the front side of the fastener 40, into which a jig 80 is fitted to turn the fastener 40.

本実施形態に係る理美容鋏１００の枢軸部９０を構成する止め板５０は、図７に示すように、板状をなし、軸体１０における頭部１１のフランジ１５より拡径の孔５１が形成されている。また、ビス止め用の穴５２が形成されている。止め板は、板状であれば形状は特に限定されず、図８に示すような円板状でもよい。 The retaining plate 50 constituting the pivot portion 90 of the hairdressing scissors 100 according to this embodiment is plate-shaped as shown in FIG. 7, and has a hole 51 with a larger diameter than the flange 15 of the head 11 of the shaft body 10. It also has a hole 52 for fastening with a screw. The shape of the retaining plate is not particularly limited as long as it is plate-shaped, and it may be a disk shape as shown in FIG. 8.

本実施形態に係る理美容鋏１００の第１刃体６０は、図２に示すように、転がり軸受２０のフランジ２３を収容する第１凹部６１と当該第１凹部６１に連通し軸部１２が挿通される第１孔６２が形成されている。また、上記の転がり軸受２０にフランジ２３を設けない構成とする場合、第１凹部は必要ではない。第２刃体７０は、図２に示すように、締結体４０を収容する第２凹部７１と当該第２凹部７１に連通し軸体１０の軸部１２が挿通される第２孔７２が形成されている。第２孔７２の内周には、軸体１０の軸部１２と螺合する雌ねじが螺刻されている。また、第２刃体７０に軸体１０の軸部１２と螺合する雌ねじを螺刻せず、第２刃体７０を軸体１０の軸部１２に螺着しない構成としてもよい。さらに、第２凹部７１を設けることなく、第２刃体７０から軸体１０の軸部１２を突出させ、突出した軸部１２に締結体４０を螺着する構成としてもよい。また、通常、第１刃体６０は静刃で、第２刃体７０は動刃であるが、上記の第１刃体が動刃で、第２刃体が静刃でもよい。 2, the first blade body 60 of the hairdressing scissors 100 according to this embodiment is formed with a first recess 61 that accommodates the flange 23 of the rolling bearing 20 and a first hole 62 that communicates with the first recess 61 and through which the shaft portion 12 is inserted. In addition, if the rolling bearing 20 is configured not to have a flange 23, the first recess is not necessary. As shown in FIG. 2, the second blade body 70 is formed with a second recess 71 that accommodates the fastener 40 and a second hole 72 that communicates with the second recess 71 and through which the shaft portion 12 of the shaft body 10 is inserted. A female thread that screws into the shaft portion 12 of the shaft body 10 is threaded on the inner circumference of the second hole 72. In addition, the second blade body 70 may not be threaded with a female thread that screws into the shaft portion 12 of the shaft body 10, and the second blade body 70 may not be threaded into the shaft portion 12 of the shaft body 10. Furthermore, the second recess 71 may not be provided, and the shaft portion 12 of the shaft body 10 may be protruded from the second blade body 70, and the fastener 40 may be screwed to the protruding shaft portion 12. Also, while the first blade body 60 is usually a stationary blade and the second blade body 70 is a moving blade, the above-mentioned first blade body may be a moving blade and the second blade body may be a stationary blade.

上記の軸体１０、転がり軸受２０、Ｅ－リング３０、締結体４０及び止め板５０を備える枢軸部９０は、図９に示すように構成されている。すなわち、転がり軸受２０は、軸体１０に嵌着され、軸体１０のくびれ箇所１３に嵌め込まれたＥ－リング３０で固着されている。転がり軸受２０が固着された軸体１０は、第１刃体６０の第１凹部６１と第１孔６２に挿通され、止め板５０は第１刃体６０の表側にビス５３で固着されている。転がり軸受２０のフランジ２３の径は、軸体１０における頭部１１のフランジ１５の径より拡径されているため、止め板５０の下側はフランジ２３の上側に当接し、止め板５０は第１刃体６０が軸体１０から離脱するのを防止する。また、第２刃体７０は、軸体１０の軸部１２に螺着されている。締結体４０は、治具８０を用いて第２凹部７１内で軸部１２に螺着され、第２刃体７０を締結している。このように、本実施形態に係る理美容鋏１００の枢軸部９０は、軸体１０、転がり軸受２０、Ｅ－リング３０、締結体４０及び止め板５０を第１刃体６０と第２刃体７０に組み付けることにより得られる簡単な構成となっている。 The pivot part 90 including the shaft body 10, rolling bearing 20, E-ring 30, fastener 40 and stop plate 50 is configured as shown in FIG. 9. That is, the rolling bearing 20 is fitted to the shaft body 10 and fixed by the E-ring 30 fitted into the necked portion 13 of the shaft body 10. The shaft body 10 to which the rolling bearing 20 is fixed is inserted into the first recess 61 and the first hole 62 of the first blade body 60, and the stop plate 50 is fixed to the front side of the first blade body 60 with a screw 53. Since the diameter of the flange 23 of the rolling bearing 20 is larger than the diameter of the flange 15 of the head 11 of the shaft body 10, the lower side of the stop plate 50 abuts against the upper side of the flange 23, and the stop plate 50 prevents the first blade body 60 from coming off the shaft body 10. The second blade body 70 is screwed to the shaft part 12 of the shaft body 10. The fastener 40 is screwed to the shaft 12 in the second recess 71 using a jig 80, fastening the second blade 70. In this way, the pivot 90 of the hairdressing scissors 100 according to this embodiment has a simple structure that is obtained by assembling the shaft 10, the rolling bearing 20, the E-ring 30, the fastener 40, and the stopper plate 50 to the first blade 60 and the second blade 70.

本実施形態に係る理美容鋏１００の枢軸部９０は、上記のように、軸体１０における頭部１１のフランジ１５の径より拡径された転がり軸受２０のフランジ２３及び止め板５０が設けられていることにより、第１刃体６０と枢軸部９０が一体となる構成となっている。そのため、治具８０を用いて軸体１０の頭部１１を左右に回し、第１刃体６０を動かすことにより、第１刃体６０と第２刃体７０の間隔の調整を行うことができる。このように、治具８０を用いて頭部１１を微妙に回すことができるという構成及び第１刃体６０を動かすという構成により、第１刃体６０と第２刃体７０の間隔の微調整を精度良く行うことができ、ひいては第１刃体６０と第２刃体７０間の噛合圧力の微調整を精度良く行うことができる。また、第１刃体６０と第２刃体７０の間隔を適度に設定することにより本実施形態に係る理美容鋏１００を触点が不要な構成とすることができる。 As described above, the pivot part 90 of the hairdressing scissors 100 according to this embodiment is configured such that the first blade 60 and the pivot part 90 are integrated by providing the flange 23 of the rolling bearing 20, which has a diameter larger than the diameter of the flange 15 of the head 11 of the shaft body 10, and the stop plate 50. Therefore, the distance between the first blade 60 and the second blade 70 can be adjusted by rotating the head 11 of the shaft body 10 left and right using the jig 80 to move the first blade 60. In this way, the configuration in which the head 11 can be delicately rotated using the jig 80 and the configuration in which the first blade 60 is moved allow for precise fine adjustment of the distance between the first blade 60 and the second blade 70, and thus allows for precise fine adjustment of the meshing pressure between the first blade 60 and the second blade 70. In addition, by appropriately setting the distance between the first blade 60 and the second blade 70, the hairdressing scissors 100 according to this embodiment can be configured to not require a contact point.

本実施形態に係る理美容鋏１００の枢軸部９０は、軸体１０の頭部１１を治具８０を用いて左右に回し、また、第２刃体内に収容される締結体４０を治具８０を用いて左右に回す構成であるため、第１刃体の表側からの出っ張り及び第２刃体の表側からの出っ張りが少なく、枢軸部９０は嵩高くない構成となっている。 The pivot part 90 of the hairdressing scissors 100 according to this embodiment is configured so that the head 11 of the shaft 10 is rotated left and right using a jig 80, and the fastener 40 housed within the second blade body is also rotated left and right using a jig 80. This means that the pivot part 90 does not protrude much from the front side of the first blade body or the front side of the second blade body, and is not bulky.

本実施形態に係る理美容鋏１００の分解・組立は、止め板５０の着脱及び治具８０を用いた締結体４０の着脱により簡単に行うことができる。 The disassembly and assembly of the hairdressing scissors 100 according to this embodiment can be easily performed by attaching and detaching the retaining plate 50 and attaching and detaching the fastener 40 using the jig 80.

本発明は、理容分野や美容分野で利用することができ、使用者に大きな福音をもたらすことができる。 This invention can be used in the barber and beauty industries, and can be a great blessing to users.
