The blade portion 21 and the handle portion 22 are connected by screwing the fastening member 4 to the female screw 21d of the connecting portion 21e and the female screw 22d of the connecting portion 22e.

この理美容鋏1Aでは、刃体部21または柄部22が破損した場合、刃体部21のみ、または、柄部22のみを交換することができる。   In the hairdressing and beauty salon 1A, when the blade part 21 or the handle part 22 is damaged, only the blade part 21 or only the handle part 22 can be replaced.

図2(a)から(c)は、理美容鋏1Aの変形例を表す図である。図1に示す理美容鋏1Aと同一の部材については同一の符号を付しその説明を省略する。また、説明の便宜上、図2(b)の上および下をそれぞれ理美容鋏1Aの上および下として説明する。   2 (a) to 2 (c) are diagrams showing a modification of the barber / beauty salon 1A. The same members as those of the hairdressing and beauty salon 1A shown in FIG. For convenience of explanation, the upper and lower parts of FIG. 2B will be described as the upper and lower parts of the hairdressing and beauty salon 1A, respectively.

図2(a)および(b)に示すように、回動受け部21bのうち連結部21eから遠い側の部分(回動受け部21bのうち、嵌合孔21c中心に対し連結部21e寄りの部分ではなく連結部21eから遠い部分)には、傾斜部21fが形成されている。図2(b)のB−1矢視断面図に示すように、傾斜部21fは、回動受け部21bから嵌合孔21c中心に向けて下方に傾斜している。   As shown in FIGS. 2A and 2B, a portion of the rotation receiving portion 21b that is far from the connection portion 21e (of the rotation reception portion 21b, closer to the connection portion 21e with respect to the center of the fitting hole 21c). An inclined portion 21f is formed in a portion far from the connecting portion 21e (not a portion). 2B, the inclined portion 21f is inclined downward from the rotation receiving portion 21b toward the center of the fitting hole 21c.

図2(a)および(b)に示すように、軸部突起22cには、傾斜部21fに係合する傾斜突起22fが形成されている。傾斜突起22fは、軸部突起22cのうち連結部22eから遠い側の部分(軸部突起22cのうち、軸部突起22c中心に対して連結部22e寄りの部分ではなく連結部22eから遠い部分)に形成されている。図2(b)のB−2矢視断面図に示すように、傾斜突起22fは、軸部突起22cの上面から軸部突起22c中心に向けて下方に傾斜している。   As shown in FIGS. 2A and 2B, the shaft protrusion 22c is formed with an inclined protrusion 22f that engages with the inclined portion 21f. The inclined protrusion 22f is a portion of the shaft portion protrusion 22c that is farther from the connecting portion 22e (the portion of the shaft portion protrusion 22c that is far from the connecting portion 22e than the portion near the connecting portion 22e with respect to the center of the shaft portion protrusion 22c). Is formed. As shown in the B-2 arrow sectional view of FIG. 2B, the inclined protrusion 22f is inclined downward from the upper surface of the shaft protrusion 22c toward the center of the shaft protrusion 22c.

刃体部21と柄部22とを連結させたとき、図2(c)に示すように、傾斜部21fと傾斜突起22fとは係合(当接)する。したがって、例えば刃体部21が内側に(他方の刃体部21に向けて)撓んだ場合や柄部22が内側に(他方の柄部22に向けて)撓んだ場合であっても、回動受け部21bの反対側の面(外側面)うち連結部21eから遠い部分21b’と、基部22bのうち連結部22eから遠い部分22b’とが離反することがない。傾斜部21fおよび傾斜突起22fを設けず、締結部材4によって連結部21eと連結部22eとが連結されているだけの場合には、刃体部21が内側に撓んだ場合や柄部22が内側に撓んだ場合には、部分21b’と部分22b’とが離反し、それによって連結部21eおよび連結部22eに応力が集中し、連結部21eまたは連結部22eが破損することが懸念される。しかし、傾斜部21fおよび傾斜突起22fが係合することにより、部分21b’と部分22b’とが離反することが防止され、連結部21eおよび連結部22eへの応力集中を避けることができる。   When the blade body portion 21 and the handle portion 22 are connected, as shown in FIG. 2C, the inclined portion 21f and the inclined protrusion 22f are engaged (contacted). Therefore, for example, even when the blade 21 is bent inward (toward the other blade 21) or the handle 22 is bent inward (toward the other handle 22). The portion 21b ′ far from the connecting portion 21e and the portion 22b ′ far from the connecting portion 22e in the base portion 22b do not separate from the opposite surface (outer surface) of the rotation receiving portion 21b. When the inclined portion 21f and the inclined protrusion 22f are not provided and the connecting portion 21e and the connecting portion 22e are merely connected by the fastening member 4, the blade portion 21 is bent inward or the handle portion 22 is When bent inward, the portion 21b ′ and the portion 22b ′ are separated from each other, thereby concentrating stress on the connecting portion 21e and the connecting portion 22e, and possibly damaging the connecting portion 21e or the connecting portion 22e. The However, the engagement between the inclined portion 21f and the inclined protrusion 22f prevents the portion 21b 'and the portion 22b' from separating, and stress concentration on the connecting portion 21e and the connecting portion 22e can be avoided.

図3は理美容鋏1Aの別の変形例を表す図である。図1に示す理美容鋏1Aと同一の部材については同一の符号を付しその説明を省略する。回動受け部21bのうち連結部21eから遠い側の部分(回動受け部21bのうち、嵌合孔21c中心に対し連結部21e寄りの部分ではなく連結部21eから遠い部分)には、二つの雌ネジ21gが形成されている。基部22bには、雌ネジ21gに整合する二つの雌ネジ22gが形成されている。雌ネジ22gは、基部22bのうち連結部22eから遠い側の部分(基部22bのうち、軸部突起22c中心に対して連結部22e寄りの部分ではなく連結部22eから遠い部分)に形成されている。雌ネジ21gおよび雌ネジ22gにはネジなどの締結部材5が螺合される。このような方法によっても、部分21b’と部分22b’とが離反することが防止され、連結部21eおよび連結部22eへの応力集中を避けることができる。   FIG. 3 is a diagram illustrating another modification of the hairdressing and beauty salon 1A. The same members as those of the hairdressing and beauty salon 1A shown in FIG. Two portions of the rotation receiving portion 21b far from the coupling portion 21e (the portion of the rotation receiving portion 21b far from the coupling portion 21e rather than the portion near the coupling portion 21e with respect to the center of the fitting hole 21c) Two female screws 21g are formed. Two female screws 22g that match the female screw 21g are formed on the base 22b. The female screw 22g is formed in a portion of the base portion 22b that is far from the connecting portion 22e (a portion of the base portion 22b that is far from the connecting portion 22e rather than a portion near the connecting portion 22e with respect to the center of the shaft protrusion 22c). Yes. A fastening member 5 such as a screw is screwed into the female screw 21g and the female screw 22g. Also by such a method, the part 21b 'and the part 22b' are prevented from being separated from each other, and stress concentration on the connecting part 21e and the connecting part 22e can be avoided.

図4に示す理美容鋏1Bは、刃体部21と柄部22とが溶接接合によって分離不能に接続されている。刃体部21と柄部22とを溶接接合する方法は、例えば、特開2016−016429に開示されているレーザを用いた接合方法を使用することができる。   In the hairdressing and beauty salon 1B shown in FIG. 4, the blade body portion 21 and the handle portion 22 are connected to each other so as not to be separated by welding. As a method of welding and joining the blade part 21 and the handle part 22, for example, a joining method using a laser disclosed in JP-A-2006-016429 can be used.

図5に示すように、医療用鉗子10は、作動部材11と、本発明の複合材料によって作製された操作部12と、作動部材11と操作部12との間に配置されたパイプ13と、パイプ13内に形成され、操作部12の操作によって作動部材11を作動(開閉および回転)させるための作動機構(不図示)と、を備えている。作動機構は、医療用鉗子において、公知の機構を採用することができる。   As shown in FIG. 5, the medical forceps 10 includes an operation member 11, an operation unit 12 made of the composite material of the present invention, a pipe 13 disposed between the operation member 11 and the operation unit 12, An operating mechanism (not shown) that is formed in the pipe 13 and operates (opens and closes and rotates) the operating member 11 by operating the operation unit 12 is provided. As the operation mechanism, a known mechanism can be adopted in the medical forceps.

<実験結果>
表1に実施例1〜4で得られた複合材料の曲げ強度、曲げ弾性率および密度を示す。表1に示すように、実施例1〜4で得られた複合材料は、曲げ強度:68〜145MPa、曲げ弾性率:4.7〜23.0GPa、密度:6.0〜13.0g/cmを有していた。
<Experimental result>
Table 1 shows the bending strength, flexural modulus, and density of the composite materials obtained in Examples 1 to 4. As shown in Table 1, the composite materials obtained in Examples 1 to 4 have a bending strength of 68 to 145 MPa, a flexural modulus of 4.7 to 23.0 GPa, and a density of 6.0 to 13.0 g / cm. 3 had.

このように、本発明の複合材料では、樹脂および金属粒子の種類や、樹脂と金属粒子との配合割合などを変えることにより、曲げ強度および曲げ弾性率などの機械的性質や、密度を変えることができる。これにより、当該複合材料から理美容鋏の柄部または医療用鉗子の操作部を作製した場合、形状は金属材料から作製した場合と同じであるが、柔軟性や重さなどの特性は使用者の要求に応じて変えることができる。そのため、理美容鋏の柄部または医療用鉗子の操作部を握った際の手の感触は変えずに、理美容鋏の柄部または医療用鉗子の操作部の特性を使用者の要求に応じて変えることができる。   As described above, in the composite material of the present invention, the mechanical properties such as the bending strength and the bending elastic modulus and the density can be changed by changing the kind of the resin and the metal particles, the blending ratio of the resin and the metal particles, and the like. Can do. Thus, when a hairdressing scissor handle or medical forceps operation part is made from the composite material, the shape is the same as that made from a metal material, but the characteristics such as flexibility and weight are the same as the user. Can be changed according to the demands. Therefore, without changing the feel of the hand when grasping the handle part of the barber / beauty salon or the operation part of the medical forceps, the characteristics of the handle part of the barber / beauty salon or the operation part of the medical forceps can be changed according to the user's request. Can be changed.

また、本発明の複合材料では、樹脂を含有しているため、金属材料と比較して柔軟性がある。これにより、当該複合材料で作製された理美容鋏の柄部または医療用鉗子の操作部は、その使用時に、金属材料から作製された理美容鋏の柄部または医療用鉗子の操作部と比較して撓るため、使用者の手首への負担が軽減され、腱鞘炎予防に役立つ可能性がある。   Further, since the composite material of the present invention contains a resin, it is more flexible than a metal material. As a result, the handle part of the barbershop or medical forceps made of the composite material is compared with the handle part of the barbershop or medical forceps made of a metal material when used. Therefore, the burden on the wrist of the user is reduced, which may help prevent tendonitis.

本発明の複合材料は、溶融した樹脂と金属粒子との混合物を冷却させることにより製造され、金属粉末射出成形法と異なり焼結されない。したがって、本発明の複合材料は、低コストで製造することができる。   The composite material of the present invention is manufactured by cooling a mixture of molten resin and metal particles, and is not sintered unlike the metal powder injection molding method. Therefore, the composite material of the present invention can be manufactured at a low cost.

本発明の製造方法で理美容鋏の柄部などを製造する場合、光沢化(鏡面仕上げ)工程にメッキを採用することができるため、金属材料から製造する場合には必要であったバフ研磨を行う必要がない。その結果、製造工程を簡略化することができると共に、製造コストを低下させることができる。   When manufacturing the handle part of a hairdressing and beauty salon with the manufacturing method of the present invention, plating can be employed in the glossing (mirror finish) process, so buffing, which was necessary when manufacturing from a metal material, is performed. There is no need to do it. As a result, the manufacturing process can be simplified and the manufacturing cost can be reduced.
