【考案の詳細な説明】
この考案は電気かみそりの外刃の改良に係り、外刃の局
部的変形を防止し、切れ味と肌の当りのすぐれた外刃パ
ターンを提供するものである。[Detailed Description of the Invention] This invention relates to an improvement of the outer blade of an electric shaver, which prevents local deformation of the outer blade and provides an outer blade pattern with excellent sharpness and good contact with the skin.
従来この種の外刃パターンは、内刃との偏摩耗を防止し
毛導入孔の開孔率を向上させるため、外刃全面を中心か
ら外周へ拡がる複数の渦巻状筋骨で分割し、これに沿っ
て長孔を配列したものが提案されているが、このもので
は、使用時の押当力により外刃が渦巻状に凹入変形する
ため、変形しない周縁固定部との間の歪が筋骨数だけ発
生し、内方との摺接具合が悪化するだけでなく破損の原
因となっていた。Conventionally, this type of outer cutter pattern was designed by dividing the entire surface of the outer cutter into multiple spiral ribs that spread from the center to the outer periphery, in order to prevent uneven wear with the inner cutter and improve the aperture rate of the hair introduction hole. A type with long holes arranged along the edge has been proposed, but with this type, the pushing force during use deforms the outer blade in a spiral shape, so the strain between it and the peripheral fixing part that does not deform is caused by the muscular bone. This occurred several times, not only worsening the sliding contact with the inner surface but also causing damage.
この考案はこれらの欠点を解消したもので、外刃表面全
体を複数個の略三角状ブロック面に均等分割し、かつ該
各ブロック面間の分割リブは波状湾曲状をなすとともに
、各ブロック面に多数の毛導入用孔を、その長軸方向が
波状湾曲状リブに沿うように配列して外刃を構成するも
のである。This invention eliminates these drawbacks by equally dividing the entire outer cutter surface into a plurality of substantially triangular block surfaces, and the dividing ribs between each block surface are wavy and curved, and each block surface is The outer cutter is constructed by arranging a large number of hair introduction holes so that the long axis direction of the holes runs along the wavy curved ribs.
以下この考案の一実施例を図面で説明する。An embodiment of this invention will be described below with reference to the drawings.
第1図は中央部1を凹陥させ、周囲に環状の断面アーチ
部2を形成したドーナツ形状の外刃で、左側に部分省略
の平面図、右側に中央断面図を表している。FIG. 1 shows a donut-shaped outer cutter in which a central portion 1 is recessed and an annular cross-sectional arch portion 2 is formed around the outer cutter, with a partially omitted plan view on the left and a central sectional view on the right.
刃面ばゆるいS字型をした波状湾曲状基線リブAで、径
方向に6等分され、各等区分された区画Bにはそれぞれ
同一のパターンが配されている。The blade surface is divided into six equal parts in the radial direction by a wavy curved base line rib A having an S-shape with a loose blade surface, and the same pattern is arranged in each equally divided section B.
刃面全体を同一のパターンの繰返しによる6等分とした
のはいかなる部分で刺毛してもほぼ同一の刺毛効果が得
られるようにしたためである。The reason why the entire blade surface is divided into six equal parts by repeating the same pattern is to ensure that almost the same bristling effect can be obtained no matter where the bristles are pricked.
各区画Bは最外周に1筋の長孔群3が、また、中央には
2筋の長孔群4が配され、これら長孔群3.4に挟まれ
て、はぼ梯形に整形された長四角形の小孔からなる短子
LIJ5が傾斜し、かつ断面アーチ部2の頂部2aより
やや外方に偏位して配されており、その一つの先端5a
がほぼ刃面の最外周に及んでいる。Each section B has one long hole group 3 on the outermost periphery and two long hole groups 4 in the center, and is sandwiched between these long hole groups 3.4 and shaped into a trapezoidal shape. A short piece LIJ5 consisting of a rectangular small hole is inclined and is arranged slightly outwardly from the apex 2a of the cross-sectional arch part 2, and one tip 5a
extends almost to the outermost circumference of the blade surface.
したがって、梯形の短孔群5の各隅を通る同心円C,D
、E、Fを描いた場合、同心円C,D間Xと、同心円E
、 F間Yとは長孔6と短孔7が併存した地帯となり、
この部分では長毛を剪断するとともに、仕上げ剃りもて
きる。Therefore, concentric circles C and D passing through each corner of the trapezoidal short hole group 5
, E, and F, the concentric circles C and D are X and the concentric circle E is
, F-Y is a zone where long hole 6 and short hole 7 coexist,
This area not only shears long hair, but also provides a finishing shave.
環状の断面アーチ部2の頂部2aが含される同心円り、
E間Zを幅広く短孔群5で占めたのは、ドーナツ型の
外刃の形状は比較的、機械的強度が弱いとされており、
皮膚の押圧によるこの部分の変形を極力防止するためで
ある。A concentric circle including the top part 2a of the annular cross-sectional arch part 2,
The reason why the short hole group 5 occupies a wide area between E and Z is because the donut-shaped outer cutter shape is said to have relatively weak mechanical strength.
This is to prevent deformation of this part due to pressure on the skin as much as possible.
また番孔3. 4. 5. 6. 7の長軸a、 b、
C,dは波状湾曲基線リブAに沿って配列されてお
り、これがため、番孔3,4゜5.6.7は各ブロック
面で半径方向に拡がって配されている。Also, number hole 3. 4. 5. 6. 7 long axes a, b,
C, d are arranged along the undulating curved baseline rib A, so that the holes 3, 4° 5, 6, 7 are arranged radially extending on each block face.
特に、上記番孔3,4,5,6,7の長軸a。In particular, the long axis a of the holes 3, 4, 5, 6, and 7.
b、 C,dが波状湾曲状基線リブAに沿って配される
ことにより、外刃の中心部から周辺へ向けての番孔3,
4,5,6.7の並びは、一度は必ず逆方向を向き、図
示しない内刃とのはさみ角が増加方向および減少方向へ
変化することになり、方向性の無秩序な長毛の導入をス
ムーズにし、この長毛を効率良く剪断できる。By arranging b, C, and d along the wavy curved base line rib A, the number holes 3,
The arrangement of 4, 5, 6, and 7 always faces in the opposite direction once, and the scissor angle with the inner cutter (not shown) changes in the increasing and decreasing directions, making it possible to smoothly introduce long hairs with disordered directionality. This allows the long hair to be sheared efficiently.
以上の構成を有するこの考案によれば、次のような効果
が得られる。According to this invention having the above configuration, the following effects can be obtained.
ブ冶ツク面を分割するリブAをゆるいS字型のような波
状湾曲状リブとしこれに沿って毛導入用孔3. 4.
5. 6. 7の長軸方向を沿わせ、この番孔をブロッ
ク面に多数配列したため、角ブロツク面は、使用時外刃
中央で受けた押当力を均等に分散できることは勿論各ブ
ロック面の力は、分割リブAに沿って毛導入孔3,4,
5,6.7の配列により、半径方向に沿って分散し、こ
れがため、外刃全体は柔らかく中心に向かって凹入変形
でき皮膚への感触を高め、かつ外刃の変形方向に長い長
孔自体も変形できるため、長毛の導入効率も高めること
ができる。The rib A that divides the block surface is a wavy curved rib like a gentle S-shape, and the hair introduction holes 3. 4.
5. 6. 7 along the long axis direction, and a large number of these holes are arranged on the block surface, so that the square block surface can not only evenly distribute the pressing force received at the center of the outer cutter when in use, but also the force on each block surface. Hair introduction holes 3, 4, along the dividing rib A
Due to the arrangement of 5, 6, and 7, they are dispersed along the radial direction, which allows the entire outer blade to be soft and deformed toward the center, increasing the feel on the skin, and having long holes in the direction of deformation of the outer blade. Since the hair itself can be deformed, the efficiency of introducing long hair can also be increased.
殊に分割リブAがゆるい波状でなく単一円弧面の場合外
刃中心から外周へ拡がり分散する押当力が方向性をもつ
ため、分割数に応じたいびつな変形を生じ、外刃割れの
原因となるが、本考案のごとくゆるいS字型で体表され
る波状湾曲状リブでは、外周の孔位置、孔数に応じて分
散するため、局部的に変形を生じることが防止でき、よ
って内刃との摺接具合も良く、切れ味と肌の当りのすぐ
れた外刃を得ることができる。In particular, when the dividing rib A is not a gently wavy shape but a single circular arc surface, the pushing force that spreads and disperses from the center of the outer blade to the outer periphery has directionality, resulting in distorted deformation depending on the number of divisions, resulting in cracking of the outer blade. However, in the case of the wavy curved rib which is represented by a loose S-shape as in the present invention, the holes are dispersed depending on the position and number of holes on the outer periphery, so local deformation can be prevented. The outer blade has good sliding contact with the inner blade and has excellent sharpness and good contact with the skin.
さらに、番孔3,4,5,6.7の長軸a。Furthermore, the long axis a of the holes 3, 4, 5, 6.7.
b、 C,dが波状湾曲状基線リブAに沿って配される
ことにより、外刃の中心ブロックから周辺へ向けてのつ
まりは半径方向での番孔の並びが、一度は必ず逆方向を
向くことになり、内刃とのはさみ角を連続的に増減変化
させることができ、無秩序な方向性の長毛の導入をスム
ースに行え、長毛の剪断効率を助長できる。By arranging b, C, and d along the wavy curved base line rib A, the arrangement of the holes in the radial direction from the center block of the outer cutter to the periphery will always be in the opposite direction. This allows the scissor angle with the inner blade to be continuously increased or decreased, allowing smooth introduction of long hair in a disordered direction, and promoting efficiency in shearing long hair.
