【産業上の利用分野】[Industrial applications]

この考案は往復式電気かみそりに関するものである。 This invention relates to a reciprocating electric razor.

【0002】[0002]

【従来の技術】[Prior art]

電気かみそりは回転式と往復式との2つに大別することができる。回転式電気 かみそりは、モータの回転軸に内刃台が直接連結された構造であり、内刃台に設 けられた内刃の回転によってひげを切断する。回転式電気かみそりは使用時の振 動が少ない特徴がある。一方、往復式電気かみそりは、モータの回転軸に偏心軸 を介してモータの回転運動を往復運動に変換する振動子が連結され、さらにこの 振動子に内刃台が連結された構造である。このため、内刃台に設けられた内刃が 往復運動してひげを切断する。往復式電気かみそりは、回転式電気かみそりに比 べると使用時の振動が大きいが、前記内刃台に多数の内刃を植立することができ るため、ひげそりの効率がよく早剃りができるという特徴がある。 The electric razor can be roughly classified into a rotary type and a reciprocating type. The rotary electric shaver has a structure in which the inner blade base is directly connected to the rotating shaft of the motor, and the whiskers are cut by the rotation of the inner blade installed on the inner blade base. The rotary electric razor is characterized by less vibration during use. On the other hand, the reciprocating electric shaver has a structure in which a vibrator for converting the rotational motion of the motor into a reciprocating motion is connected to the rotary shaft of the motor via an eccentric shaft, and further an inner blade base is connected to the vibrator. Therefore, the inner blade provided on the inner blade base reciprocates to cut the beard. Reciprocating electric razors generate more vibrations during use than rotary electric razors, but since many inner blades can be planted on the inner blade base, shaving is efficient and quick shaving is possible. There is a feature that you can do it.

【0003】 従来の往復式電気かみそりを図1から図3に示す。図1は二連の刃を備えた往 復式電気かみそりの外観図であり、本体ケース1の一側面に駆動スイッチノブ2 が設けられ、他側面にトリマ−3とトリマ−スライドスイッチ4とが一体に設け られている。また本体ケース1のヘッド部に外刃5がアーチ状に張設されている 。A conventional reciprocating electric shaver is shown in FIGS. 1 to 3. FIG. 1 is an external view of a forward and backward electric razor equipped with two blades. A drive switch knob 2 is provided on one side of the main body case 1, and a trimmer-3 and a trimmer slide switch 4 are integrated on the other side. It is provided in. An outer blade 5 is stretched in an arch shape on the head portion of the main body case 1.

【0004】 図2は図1に示す往復式電気かみそりの駆動系分解斜視図である。モータ6の 回転軸に偏心軸7が連結され、偏心軸7の各軸心に2つの振動レバー8がそれぞ れ連結されている。各振動レバー8の先端にはそれぞれ振動子9が連結される。 前記偏心軸7の各軸心はモータの回転軸に対して左右対称に設けられているので 、2つの振動子9は互いに逆方向に往復運動する。2つの振動子9を互いに逆方 向に往復運動させると、往復運動時に発生する振動を互いに相殺させることがで き、振動の低減を図ることができる。FIG. 2 is an exploded perspective view of a drive system of the reciprocating electric shaver shown in FIG. An eccentric shaft 7 is connected to the rotating shaft of the motor 6, and two vibration levers 8 are connected to each shaft center of the eccentric shaft 7. A vibrator 9 is connected to the tip of each vibration lever 8. Since each axis of the eccentric shaft 7 is provided symmetrically with respect to the rotation axis of the motor, the two oscillators 9 reciprocate in opposite directions. When the two oscillators 9 are reciprocally moved in opposite directions, the vibrations generated during the reciprocating motion can be canceled by each other, and the vibrations can be reduced.

【0005】 さて、振動子9は中央部から上方に向かって突出軸10が設けられている。突 出軸10には毛屑が内部に入り込むのを防止するゴム製の毛止め11を介して内 刃台12が取り付けられる。また内刃台12には複数の内刃素片13が所定の間 隔で整然と植立されている。前記突出軸10と内刃台12との連結は、突出軸1 0に設けられた係合用の孔14と、内刃台12の下面中央部に設けられた係合突 起15(図3a参照)とによって行われる。前記突出軸10と内刃台12との連 結の際、スプリング16を挿入しておく。スプリング16は前記外刃5との接触 圧を調整したり、またひげそり時の外圧を吸収して肌との接触圧を適切にする。The vibrator 9 is provided with a protruding shaft 10 which extends upward from the central portion. An inner cutter base 12 is attached to the protrusion shaft 10 via a rubber hair stopper 11 that prevents dust from entering the inside. In addition, a plurality of inner blade pieces 13 are planted on the inner blade base 12 at regular intervals. The protrusion shaft 10 and the inner blade base 12 are connected by an engagement hole 14 provided in the protrusion shaft 10 and an engagement protrusion 15 provided in a central portion of the lower surface of the inner blade base 12 (see FIG. 3a). ) And by. When connecting the protruding shaft 10 and the inner blade base 12, a spring 16 is inserted. The spring 16 adjusts the contact pressure with the outer blade 5 and absorbs the outer pressure at the time of shaving to make the contact pressure with the skin appropriate.

【0006】[0006]

【考案が解決しようとする課題】[Problems to be solved by the device]

以上のような構成の往復式電気かみそりは、前記内刃台12が往復運動時に上 下に振れる傾向がある。これは、前記振動子の突出軸10と内刃台12とが中央 部の一点で連結されているため、往復反転時に連結部分を支点にしてシーソー運 動するからである(図3b参照)。その結果、内刃素片13の往復動方向の端部 で前記外刃5の内面と離れたり極度に押しつけられたりして接触圧が変化してし まう。このため、前記端部でひげそりが不均一となったり、内刃素片13や外刃 5の内面が偏摩耗してしまうという欠点がある。 In the reciprocating electric shaver having the above structure, the inner blade base 12 tends to swing up and down during the reciprocating motion. This is because the protruding shaft 10 of the vibrator and the inner blade base 12 are connected at one point in the central portion, and therefore, when the reciprocating reversal is performed, the seesaw moves around the connecting portion as a fulcrum (see FIG. 3b). As a result, the contact pressure changes due to the end of the inner blade element 13 in the reciprocating direction being separated from the inner surface of the outer blade 5 or being extremely pressed. Therefore, there are disadvantages that the shaving becomes uneven at the end portion and the inner surfaces of the inner blade element 13 and the outer blade 5 are unevenly worn.

【0007】 従って、この考案の目的は、内刃台の往復反転時のシーソー運動による内刃素 片や外刃の内面の偏摩耗を防止することにある。Therefore, an object of the present invention is to prevent uneven wear of the inner surfaces of the inner blade element and the outer blade due to the seesaw movement when the inner blade base is reciprocally reversed.

【0008】[0008]

【課題を解決するための手段】[Means for Solving the Problems]

この考案の構成は、内刃が、内刃台と、この内刃台に所定の間隔で複数枚植立 された内刃素片とから構成され、前記内刃台はモータの回転運動を往復運動に変 換する振動子の突出軸に対して前記内刃台の往復動方向の中央部で連結される。 そして前記内刃素片は前記内刃台の端部側にある素片上端と前記外刃内面との間 に間隙を形成するように植立される。 According to the structure of the present invention, the inner blade is composed of an inner blade base and a plurality of inner blade pieces that are planted on the inner blade base at a predetermined interval. The inner blade base reciprocates the rotational movement of the motor. The central axis of the inner blade base in the reciprocating direction is connected to the projecting shaft of the oscillator that is converted into motion. Then, the inner blade element is planted so as to form a gap between the upper end of the element on the end side of the inner blade base and the inner surface of the outer blade.

【0009】 また、前記内刃素片は、前記内刃台の中央部から端部に向かって素片上端と前 記外刃内面との間の間隙が順次大きくなるように植立される。Further, the inner blade pieces are erected such that the gap between the upper end of the piece and the inner surface of the outer blade is gradually increased from the central portion to the end portion of the inner blade base.

【0010】[0010]

【作用】[Action]

この考案によれば、内刃素片が、内刃台の端部側にある素片上端と前記外刃内 面との間に間隙を形成するように植立されているので、内刃台の往復反転時にシ ーソー運動が生じても、内刃台の端部に植立された内刃素片の上端が外刃の内面 に極度に押しつけられることを抑え、内刃素片や外刃内面の偏摩耗を防止できる 。 According to this invention, the inner blade piece is erected so as to form a gap between the upper end of the piece on the end side of the inner blade base and the inner surface of the outer blade base. Even if a seesaw motion occurs when reciprocating the blade, the upper edge of the inner blade element that is planted at the end of the inner blade base is prevented from being excessively pressed against the inner surface of the outer blade, and the inner blade element and outer blade are prevented. Uneven wear on the inner surface can be prevented.

【0011】 またこの考案によれば、内刃素片が、内刃台の中央部から端部に向かって素片 上端と前記外刃内面との間の間隙が順次大きくなるように植立されているので、 前記シーソー運動時に内刃素片の上端が外刃内面に沿うようにして外刃内面と接 近する。このため、内刃素片や外刃内面の偏摩耗を防止しながら、素片上端と外 刃内面との圧接状態を適切に保ち良好な剃り味を保持することができる。According to this invention, the inner blade pieces are erected so that the gap between the upper end of the inner blade and the inner surface of the outer blade increases in order from the center to the end of the inner blade base. Therefore, during the seesaw movement, the upper end of the inner blade element is brought into close contact with the inner surface of the outer blade so that the upper end of the inner blade element is along the inner surface of the outer blade. Therefore, while preventing uneven wear of the inner blade element and the inner surface of the outer blade, it is possible to properly maintain the pressure contact state between the upper end of the element and the inner surface of the outer blade and maintain a good shaving taste.

【実施例】【Example】

以下本考案の実施例を図面に基づき説明する。図4は本考案による往復式電気 かみそりの内刃及び外刃の正面図である。なお、この内刃は前述の従来例のもの と同様にして往復式電気かみそりに組み込まれる。この内刃は、樹脂製の内刃台 12に内刃素片13が所定の間隔で複数枚植立されている。内刃素片13は例え ばステンレスの素材にセラミックがコーティングされており、刃先硬度が高くま たエッジが鋭くなっている。内刃素片13は半円状に形成され、底辺の部分が前 記内刃台に埋め込まれるようにインサート成形される。 An embodiment of the present invention will be described below with reference to the drawings. FIG. 4 is a front view of an inner blade and an outer blade of a reciprocating electric shaver according to the present invention. The inner blade is incorporated into the reciprocating electric shaver in the same manner as the above-mentioned conventional example. In this inner blade, a plurality of inner blade pieces 13 are planted at a predetermined interval on an inner blade base 12 made of resin. The inner blade element 13 is made of, for example, a stainless steel material coated with ceramic, and has a high edge hardness and a sharp edge. The inner blade element 13 is formed in a semicircular shape, and is insert-molded so that the bottom portion is embedded in the inner blade base.

【0013】 さて、この内刃素片13の円弧の上端は内刃台12の中央部が高く、端部が低 くなるように設けられている。例えば、図4aは、内刃素片13の上端を通る軌 跡が内刃台12の長手方向中心点と両端部の各上端の3点を通る円弧状になって いる。また図4bは、前記3点を通る楕円状に形成されている。また図4cは内 刃台を長手方向に3等分し、中央部分Aを同一高さにして、両端部分を円弧状に して、端部を最も低くしたものである。By the way, the upper end of the arc of the inner blade element 13 is provided so that the central portion of the inner blade base 12 is high and the end portion is low. For example, in FIG. 4a, a track passing through the upper end of the inner blade element 13 has an arc shape passing through a center point in the longitudinal direction of the inner blade base 12 and three points at each upper end of both ends. Further, FIG. 4b is formed in an elliptical shape passing through the three points. Further, FIG. 4c shows that the inner blade base is divided into three equal parts in the longitudinal direction, the central portion A has the same height, both end portions have an arc shape, and the end portions have the lowest height.

【0014】 このように本考案による往復式電気かみそりの内刃素片13の上端は内刃台1 2の長手方向の両端部で最も低く設けられているので、外刃5の内面との間に間 隙を形成することができる。このため、内刃台の往復反転時にシーソー運動が生 じても、内刃素片が外刃の内面に極度に押しつけられることを抑え、内刃素片や 外刃の内面の偏摩耗を防止できる。As described above, since the upper end of the inner blade element 13 of the reciprocating electric shaver according to the present invention is provided at the lowest at both longitudinal end portions of the inner blade base 12, the space between the inner blade 13 and the inner surface of the outer blade 5 is reduced. A gap can be formed in Therefore, even if a seesaw motion occurs when the inner blade base is turned back and forth, the inner blade element is prevented from being excessively pressed against the inner surface of the outer blade, and uneven wear of the inner surface of the inner blade element and the outer blade is prevented. it can.

【0015】 特に図4a及びbのように、内刃素片13が、内刃台の中心点から端部に向か って素片13の上端と前記外刃5の内面との間の間隙が順次に大きくなるように 植立すれば、前記シーソー運動時に内刃素片13の上端が外刃5の内面に沿うよ うにして外刃5の内面と接近する。このため、内刃素片13や外刃5の内面の偏 摩耗を防止しながら、素片13の上端と外刃5の内面との圧接状態を適切に保ち 良好な剃り味を保持することができる。In particular, as shown in FIGS. 4 a and 4 b, the inner blade element 13 has a gap between the upper end of the element 13 and the inner surface of the outer blade 5 from the center point of the inner blade base toward the end. When the seesaw is moved, the upper end of the inner blade element 13 approaches the inner surface of the outer blade 5 so as to follow the inner surface of the outer blade 5. Therefore, while preventing uneven wear of the inner surfaces of the inner blade piece 13 and the outer blade 5, it is possible to properly maintain the pressure contact state between the upper end of the piece 13 and the inner surface of the outer blade 5 and maintain a good shaving taste. it can.

【考案の効果】[Effect of device]

この考案によれば、内刃素片が、内刃台の端部側にある素片上端と前記外刃内 面との間に間隙を形成するように植立されているので、内刃台の往復反転時にシ ーソー運動が生じても、内刃台の端部に植立された内刃素片の上端が外刃の内面 に押しつけられることを抑え、内刃素片や外刃内面の偏摩耗を防止できる。 According to this invention, the inner blade piece is erected so as to form a gap between the upper end of the piece on the end side of the inner blade base and the inner surface of the outer blade base. Even if a seesaw motion occurs when reciprocating, the upper edge of the inner blade element that is planted at the end of the inner blade base is prevented from being pressed against the inner surface of the outer blade, and Uneven wear can be prevented.

【0017】 またこの考案によれば、内刃素片が、内刃台の中央部から端部に向かって素片 上端と前記外刃内面との間の間隙が順次大きくなるように植立されているので、 前記シーソー運動時に内刃素片の上端が外刃内面に沿うようにして外刃内面と接 近する。このため、内刃素片や外刃内面の偏摩耗を防止しながら、素片上端と外 刃内面との圧接状態を適切に保ち良好な剃り味を保持することができる。According to this invention, the inner blade element is planted such that the gap between the upper end of the element blade and the inner surface of the outer blade is gradually increased from the center to the end of the inner blade base. Therefore, during the seesaw movement, the upper end of the inner blade element is brought into close contact with the inner surface of the outer blade so that the upper end of the inner blade element is along the inner surface of the outer blade. Therefore, while preventing uneven wear of the inner blade element and the inner surface of the outer blade, it is possible to properly maintain the pressure contact state between the upper end of the element and the inner surface of the outer blade and maintain a good shaving taste.

【0018】 その結果、内刃または外刃を長期にわたって使用でき、また、内刃素片と外刃 との接触面積が低減して負荷を軽くし、電力消費等を低くすることもできる。As a result, the inner blade or the outer blade can be used for a long period of time, and the contact area between the inner blade element and the outer blade can be reduced to reduce the load and reduce power consumption and the like.
