所定の刃厚のところに配してなる。そして、固定刃1
・可動刃2とも金属製のものに比べて、刃の切れ味及び
この寿命の向上を図るために、少なくとも固定刃1がフ
ァインセラミックスで形成されている。As shown in Figs. 3 and 4, the conventional hair cutter 7 blade is attached to one longitudinal end of the hair cutter main body, which has a built-in motor and a drive unit having an eccentric shaft as its output shaft. , is driven by engaging the scale portion 4b of the guide plate 4 with the eccentric shaft. This hair cutter blade has a comb-shaped first cutting blade 1.
It is formed from a fixed blade 1 having a fixed blade 1 and a movable blade 2 having a comb-shaped second cutting blade 2a that is pressed against the fixed blade 1 and slides back and forth.
In addition, since the blade thickness of the first cutting blade 1a of the fixed blade 1 tapers toward the tip, the tip of the second cutting blade 2a of the movable blade 2 is cut to a predetermined height to leave the hair uncut. It is arranged at a predetermined blade thickness of the fixed blade 1. And fixed blade 1
- At least the fixed blade 1 is made of fine ceramics in order to improve the sharpness and life of the movable blade 2 compared to those made of metal.
前述したようなヘアーカンタ−刃は、固定刃をファイン
セラミックスで形成しているため、これに落下等による
強い衝撃がかかると、割れ易く、特にこの端部に位置す
る切刃の破1貝がある。また、固定刃の切刃の外面が直
線状に形成されているため、例えば頭部に使用した場合
、局部的に接触圧が大きいところができて肌当たりを悪
くしている。The hair canter blade mentioned above has a fixed blade made of fine ceramics, so if it is subjected to a strong impact due to a fall, etc., it is likely to break, and in particular, the cutting blade located at this end will break. be. Furthermore, since the outer surface of the cutting edge of the fixed blade is formed in a straight line, when used, for example, on the head, there are areas where the contact pressure is locally large, making it uncomfortable to touch the skin.
本発明は、このような事由に鑑みてなしたもので、その
目的とするところは、端部側の耐落下強度を上げるとと
もに肌当たり性の優れたヘアーカッター刃を提供するに
ある。The present invention has been made in view of the above circumstances, and its purpose is to provide a hair cutter blade that has increased drop resistance on the end side and has excellent skin contact.
[課題を解決するための手段]
上記した目的を達成するために、本発明のへアーカッタ
ー刃は、櫛状の切刃を有する固定刃と、これに圧接され
て往復摺動する櫛状の切刃を有する可動刃とから形成さ
れ、かつ、毛を所定の刈り残し高さに切断するよう固定
刃と可動刃の両切刃を配してなり、少なくとも固定刃が
ファインセラミックスで形成されたヘアーカッター刃に
おいて、前記固定刃の刃厚を、刈り残し高さを決定する
中央部分に対し、端部側を厚くした構成としている。[Means for Solving the Problems] In order to achieve the above-mentioned object, the hair cutter blade of the present invention includes a fixed blade having a comb-shaped cutting edge, and a comb-shaped fixed blade that is pressed against the fixed blade and slides back and forth. A movable blade having a cutting edge, and a fixed blade and a movable cutting blade arranged to cut the hair to a predetermined uncut height, and at least the fixed blade is made of fine ceramics. In the hair cutter blade, the blade thickness of the fixed blade is thicker at the end portion than at the center portion, which determines the uncut height.
この構成によれば、所定の刈り残し高さを得る性能を下
げることなく、端部の切刃の断面積が大きくとれ、端部
の切刃の許容外力が大きくとれる。According to this configuration, the cross-sectional area of the cutting blade at the end can be increased, and the allowable external force of the cutting blade at the end can be increased, without reducing the performance of obtaining a predetermined uncut height.
さらに、固定刃の切刃の刃厚を中央部より端部を厚クシ
て、この切刃の外面を凹状にしているので、固定刃と例
えば頭部との接触圧分布がなだらかにできる。Further, since the cutting edge of the fixed blade is thicker at the end than at the center and the outer surface of the cutting edge is concave, the contact pressure distribution between the fixed blade and, for example, the head can be smooth.
以下、本発明の第1実施例を第1図に基づいて説明する
。先に説明した従来例と実質的に同一の部材には同一の
符号を何して説明する。Hereinafter, a first embodiment of the present invention will be described based on FIG. The same reference numerals will be used to refer to substantially the same members as in the conventional example described above.
1は固定刃で、ファインセラミックス材の射出成形でな
り、第1切刃1aが形成されている。そして、プラスチ
ックにて成形された基板3に固着される。この第1切刃
1aの刃厚は、刃元から刃先にかけて薄く形成されてい
る。A fixed blade 1 is made by injection molding of fine ceramic material, and has a first cutting edge 1a formed therein. Then, it is fixed to a substrate 3 made of plastic. The blade thickness of this first cutting edge 1a is formed thin from the blade base to the blade tip.
2は可動刃で、ファインセラミックス材でつくられるも
のは固定刃1と同様にして形成されるが、金属製の場合

・押さえばねがブロック化され、かつ、可動刃2は固
定刃1に対して略往復自在に支持される。Reference numeral 2 designates a movable blade, and if it is made of fine ceramics, it is formed in the same manner as fixed blade 1, but if it is made of metal, this second cutting blade 2a is formed by punching and forming a metal plate, and then grinding it. are doing. This movable blade 2 is pressed against the fixed blade 1 using a reaction force of a torsional force of a presser spring (not shown), which will be described later. The presser springs are torsion coil springs, and two of them are located symmetrically with respect to the center axis of the board 3, and each has one end connected to a locking part (not shown) provided on the board 3, and the other end connected to a locking part (not shown) provided on the board 3. is attached to the movable blade 2 by being hooked onto the locking portion 4d of the guide plate 4 attached to the movable blade 2. With this installation, fixed blade 1 and movable blade 2
- The presser spring is made into a block, and the movable blade 2 is supported with respect to the fixed blade 1 in a substantially reciprocating manner.
本発明の要部は、前記固定刃1の第1切刃1aにある。The main part of the present invention resides in the first cutting edge 1a of the fixed blade 1.
この第1切刃1aの刃厚を、中央部分より端部1b側に
向かって徐々に厚く形成している。これにより、固定刃
1の第1切刃1aの外面が凹状となる。この結果、固定
刃1と例えば頭部との接触圧分布がなだらかになり、肌
当たりをやわらか(するとともに頭に沿い易くなる。な
お、両端部1b、1bの第1切刃1aの刃厚のみ厚くす
るようにしてもよい。The thickness of the first cutting edge 1a is gradually increased from the center toward the end 1b. Thereby, the outer surface of the first cutting edge 1a of the fixed blade 1 becomes concave. As a result, the contact pressure distribution between the fixed blade 1 and, for example, the head becomes gentle, making it soft against the skin (as well as making it easier to follow the head. Note that only the blade thickness of the first cutting blade 1a at both ends 1b, 1b) It may be made thicker.
次に、本発明の第2実施例を第2図に基づいて説明する
。Next, a second embodiment of the present invention will be described based on FIG. 2.
本発明の要部は、前記可動刃1の第2切刃2aにある。The main part of the present invention resides in the second cutting edge 2a of the movable blade 1.
この要部以外の部材は、先に説明した第1実施例と同様
であるので、実質的に同一の部材には同一の符号を付し
て詳細な説明は省略する。Members other than this essential part are the same as those in the first embodiment described above, so substantially the same members are given the same reference numerals and detailed explanations will be omitted.
この第2切刃2aの先端を、固定刃1の第1切刃1aの
先端に対して、第1切刃1aの刃厚に応じて、刃厚の厚
いところは近づけ、薄いところは離している。すなわち
、第1切刃1aの所定の刈り残し高さ相当の刃厚部分に
略位置させている。この結果、第1切刃1aと第2切刃
2aの先端間の寸法は、固定刃1の第1切刃1aの中央
部から端部1bに向けて小さくなっている。このように
することにより、第1実施例に比べてさらに刈り残し高
さを正確に均一化することができる。The tip of the second cutting edge 2a is moved closer to the tip of the first cutting edge 1a of the fixed blade 1 depending on the thickness of the first cutting edge 1a, and closer to the edge where the blade is thicker and farther away from where it is thinner. There is. That is, the first cutting edge 1a is located approximately at a blade thickness portion corresponding to a predetermined uncut height. As a result, the dimension between the tips of the first cutting edge 1a and the second cutting edge 2a becomes smaller from the center of the first cutting edge 1a of the fixed blade 1 toward the end 1b. By doing so, it is possible to more accurately equalize the uncut height than in the first embodiment.
本発明のへアーカノター刃は、所定の刈り残し高さを得
る性能を下げることなく、端部の切刃の断面積を大きく
して、この許容外ノjを大きくし、かつ、固定刃の切刃
の刃厚を中央部より端部を厚くして、この切刃の外面を
凹状にして、固定刃と例えば頭部との接触圧分布をなだ
らかにしたので、ヘアーカッター刃の耐衝撃性と脱出た
り性の向上が図れる。The hair cutter blade of the present invention increases the cross-sectional area of the cutting edge at the end without reducing the performance of obtaining a predetermined uncut height, increases this permissible notch j, and improves the cutting edge of the fixed blade. The edge of the blade is thicker than the center, and the outer surface of this cutting edge is concave to smooth the contact pressure distribution between the fixed blade and, for example, the head, which improves the impact resistance of the hair cutter blade. You can improve your ability to escape.
