Description
【０００１】[0001]
本考案は、往復摺動式電気かみそり、特に外刃及び内刃の構造に関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reciprocating sliding electric shaver, and more particularly to a structure of an outer blade and an inner blade.
【０００２】[0002]
これまで提案されている往復摺動式電気かみそりは、外刃を一枚の長方形薄板 をそのまま中央部分でＵ字形に折り曲げたものを使用しており、このＵ字形状外 刃の頂部はその長手方向において平坦となる。顔の平坦な部位を剃るときにはこ のような平坦な外刃でも肌との密接度はよいが、このような平坦な部位はむしろ 少なく、大部分において微妙に湾曲している。このため、このような湾曲部位に おいては外刃と肌の密接度は悪く、また外刃が肌に接する部分も狭い。このため に、何度か繰り返し剃らなければならなかった。 The reciprocating sliding electric razors that have been proposed so far use an outer blade made by bending a single rectangular thin plate into a U-shape at its central portion, and the top of this U-shaped outer blade has its longitudinal length. Flat in the direction. When shaving a flat part of the face, even a flat outer blade such as this has a good degree of close contact with the skin, but such a flat part is rather small, and most of them are slightly curved. Therefore, in such a curved portion, the outer blade and the skin are not closely attached, and the portion where the outer blade is in contact with the skin is narrow. For this, I had to shave several times.
【０００３】 更に、上記往復摺動式電気かみそりにおいて内刃がその中央部に設けた支軸の みで往復駆動されるものにあっては、その往復摺動の両末端部分で外刃と内刃と の間に隙間が生じ易く、切れ味がおちる。このような隙間をなくすには、内刃を 外刃に圧接するバネ力を大きくしなければならず、これは外刃ないし内刃の摩耗 の原因となり好ましくない。Further, in the reciprocating slide type electric shaver, in which the inner blade is reciprocally driven only by the support shaft provided in the central portion, the inner blade and the inner blade are reciprocally slid at both ends. A gap is likely to be created between the blade and the blade, resulting in sharpness. In order to eliminate such a gap, it is necessary to increase the spring force that presses the inner blade against the outer blade, which causes wear of the outer blade and the inner blade, which is not preferable.
【０００４】[0004]
本考案は、従来型往復摺動式電気かみそりの上記欠点に鑑み、外刃と肌の接触 感及びその接触面積を拡大し、そして外刃と内刃との密接度を高めて、剃り味の よい往復摺動式電気かみそりを堤供することにある。 In view of the above-mentioned drawbacks of the conventional reciprocating sliding electric shaver, the present invention expands the contact feeling between the outer blade and the skin and the contact area, and increases the closeness of contact between the outer blade and the inner blade to improve the shaving taste. It is to provide a good reciprocating sliding electric razor.

上記目的のため、縦断面が略Ｕ字形の外刃と当該外刃に接して往復摺動する内 刃からなる往復摺動式電気かみそりにおいて、前記外刃の頂部がその長手方向に 緩やかな円弧を形成し、そして前記内刃を構成する複数の小刃がそれぞれ前記円 弧の中心に向けて配列され、かつ外刃に弾接していることを特徴とする。 For the above-mentioned purpose, in a reciprocating sliding electric shaver comprising an outer blade having a substantially U-shaped vertical section and an inner blade that reciprocally slides in contact with the outer blade, the top of the outer blade has a gentle arc in its longitudinal direction. And a plurality of small blades forming the inner blade are arranged toward the center of the arc and are in elastic contact with the outer blade.

図１は、本考案に基づく往復摺動式電気かみそりの一部を断面した正面図、図 ２は図１の上部中央縦断面図、図３は本考案に基づく外刃の外観図、図４は内刃 台と移動片の係合状態を示す図であり、電気かみそりは、全体として、本体１お よびこの本体１の上部に着脱可能に取り付けられたカバー２の二部分から構成さ れ、このカバー２の上方開放端部に、その内側から上方に突出する形で外刃３が 取り付けられている。 1 is a front view of a part of a reciprocating sliding type electric shaver according to the present invention, FIG. 2 is a vertical cross-sectional view of the upper center of FIG. 1, FIG. 3 is an external view of an outer blade according to the present invention, and FIG. FIG. 3 is a view showing an engagement state between an inner blade base and a movable piece, and the electric shaver is composed of a main body 1 and a cover 2 detachably attached to an upper portion of the main body 1, as a whole, An outer blade 3 is attached to the upper open end of the cover 2 so as to project upward from the inside.
【０００７】 図１に見られるように、この外刃３はその長手方向において緩やかな円弧状に 湾曲しており、もう一方の方向においては、図２及び図３に示すように、全体と して逆Ｕ字形を呈している。そして、この外刃３の相対向する下方端部の外側に 、樹脂で形成した外刃枠４がそれぞれ固着されている。この外刃枠４は、前記カ バー２内において、外刃３自体の弾性によってカバー２の内壁と接し、外刃３を 所定の位置に保持するものである。As shown in FIG. 1, the outer blade 3 is curved in a gentle arc shape in the longitudinal direction, and in the other direction, as shown in FIGS. Has an inverted U shape. The outer blade frames 4 made of resin are fixed to the outer sides of the lower ends of the outer blades 3 which face each other. In the cover 2, the outer cutter frame 4 contacts the inner wall of the cover 2 by the elasticity of the outer cutter 3 itself, and holds the outer cutter 3 at a predetermined position.
【０００８】 外刃３は、肌に押し付けられることによって変形し、この変形によって割れる ことがある。従って、それを防止するため外刃３が内方（下方）に微少移動でき るように設けている。そのため、外刃３の下方移動を規制する突起５がカバー２ の内壁に一体的に形成されている。また、外刃枠４の上端がカバー２の上方開放 端部の内側周縁部２，と当接し、外刃３はカバー２から上方へ離脱することはな い。The outer blade 3 may be deformed by being pressed against the skin and may be broken by this deformation. Therefore, in order to prevent this, the outer blade 3 is provided so that it can be slightly moved inward (downward). Therefore, the projection 5 that restricts the downward movement of the outer blade 3 is integrally formed on the inner wall of the cover 2. Further, the upper end of the outer cutter frame 4 contacts the inner peripheral edge portion 2 of the upper open end of the cover 2, and the outer cutter 3 does not separate upward from the cover 2.
【０００９】 なお、外刃３はその長手方向及びそれと直行する方向の両方向において湾曲し ているため、電鋳加工技術を利用して成形する。まず、外刃３の展開平面図をも とにネガフィルムを作り、このフィルムを使用して金属導電体上に、露光、現像 、焼付を行う。その後、それを所定形状に絞って３次元立体形状の母型を造り、 そしてこの母型に電着を繰り返し行い所定厚みに形成したものである。Since the outer blade 3 is curved in both the longitudinal direction and the direction orthogonal to the outer blade 3, the outer blade 3 is molded by using an electroforming technique. First, a negative film is prepared based on the developed plan view of the outer blade 3, and the film is used to perform exposure, development and printing on a metal conductor. After that, it is squeezed into a predetermined shape to form a three-dimensional three-dimensional master block, and this master block is repeatedly electrodeposited to form a predetermined thickness.
【００１０】 本体１の上方部分には隔壁６が設けられ、この隔壁６の中央部分にトラック状 の開孔７が形成されている。また、この隔壁６の内側には、後述する内刃８を往 復摺動させる移動片９が配置されている。この移動片９は、樹脂成形部材で、両 側部に形成された略Ｕ字形の脚部１０と、この両脚部１０間に形成された内刃駆 動部１１とからなり、前記脚部１０の上方端部が前記隔壁６の下側に固着される ことによって、本体１に固定されている。A partition wall 6 is provided in an upper portion of the main body 1, and a track-shaped opening 7 is formed in a central portion of the partition wall 6. Further, inside the partition wall 6, a moving piece 9 for sliding an inner blade 8 described later back and forth is arranged. The moving piece 9 is a resin molded member and is composed of a substantially U-shaped leg portion 10 formed on both sides and an inner blade driving portion 11 formed between the both leg portions 10. The upper end of the is fixed to the lower side of the partition wall 6 so that it is fixed to the main body 1.
【００１１】 前記内刃駆動部１１は、前記隔壁６の開孔７と同様に略平行な二面を有するト ラック状の断面形状を有し、前記開孔７を通って上方に延びている。そして、こ の内刃駆動部１１の基部近傍には補助片１２が軸支され、当該補助片１２がモー タ（図示せず。）の回転軸１３に固定した偏心軸１４と係合している。従って、 モータの回転が偏心軸１４と補助片１２を介して移動片９へ伝えられ、移動片９ が前記トラック状の開孔７に案内されて、当該開孔７内を左右方向（図１）に揺 動する。また、前記移動片９の内刃駆動部１１には縦溝１５が形成されて、その 内部に内刃８を上方へ押圧する押圧バネ１６が配され、その上部周縁部には内刃 ８を保持するための切り欠き１７が形成されている。The inner blade driving unit 11 has a track-shaped cross-sectional shape having two surfaces that are substantially parallel to each other similarly to the opening 7 of the partition wall 6, and extends upward through the opening 7. .. An auxiliary piece 12 is pivotally supported near the base of the inner blade driving section 11, and the auxiliary piece 12 engages with an eccentric shaft 14 fixed to a rotary shaft 13 of a motor (not shown). There is. Therefore, the rotation of the motor is transmitted to the moving piece 9 via the eccentric shaft 14 and the auxiliary piece 12, and the moving piece 9 is guided to the track-shaped opening 7 to move in the opening 7 in the left-right direction (see FIG. 1). ). Further, a vertical groove 15 is formed in the inner blade driving portion 11 of the moving piece 9, and a pressing spring 16 for pressing the inner blade 8 upward is arranged therein, and the inner blade 8 is provided on the upper peripheral portion thereof. A notch 17 for holding is formed.
【００１２】 内刃８は、内刃台１８とこの内刃台１８に立設された複数の小刃１９からなり 、内刃台１８は長方形の枠部２０と取付部２１からなる。この取付部２１は枠部 ２０の下側中央部分に形成された突状片で、前記内刃駆動部１１の縦溝１５に挿 通し、同時に公知の方法で前記切り欠き１７にその側部を嵌合させ、内刃８が容 易に離脱しないように保持している。さらに、この取付部２１の下方端は、前記 押圧バネ１６の上端に当接し、この押圧バネ１６の作用を受ける。従って、内刃 ８はこの押圧バネ１６によって常に上方に付勢され、常に外刃３の内壁面と弾接 している。また、前記内刃駆動部１１の上端は枠部２０の内側にまで伸びており 、内刃駆動部１１の両平坦面１１’と枠部２０の内側が当接することによって、 内刃８の水平方向の回動が規制されている。The inner blade 8 includes an inner blade base 18 and a plurality of small blades 19 provided upright on the inner blade base 18, and the inner blade base 18 includes a rectangular frame portion 20 and a mounting portion 21. The mounting portion 21 is a projecting piece formed in the lower central portion of the frame portion 20, and is inserted into the vertical groove 15 of the inner blade driving portion 11, and at the same time, the side portion thereof is formed in the notch 17 by a known method. The inner blade 8 is fitted and held so as not to easily come off. Further, the lower end of the mounting portion 21 contacts the upper end of the pressing spring 16 and receives the action of the pressing spring 16. Therefore, the inner blade 8 is always biased upward by the pressing spring 16 and is always in elastic contact with the inner wall surface of the outer blade 3. In addition, the upper end of the inner blade driving unit 11 extends to the inside of the frame unit 20, and the flat surfaces 11 ′ of the inner blade driving unit 11 and the inner side of the frame unit 20 contact each other, so that the inner blade 8 moves horizontally. Rotation in the direction is restricted.
【００１３】 前記枠部２０の上面には、等間隔で複数の小刃１９を立設している。これらの 小刃１９は、かまぼこ形状の薄板で構成し、その上方エッジは外刃３の内壁面の 形状に対応して円弧状に並置整列されている。このように、内刃８は全体として 外刃３に対応した円弧状を有し、個々の小刃１９はそれぞれ対応する外刃３の内 壁に対して直角に固定されている。すなわち、図１に示したように、各小刃１９ は前記外刃３の円弧の中心に向かって扇形に配列されている。On the upper surface of the frame portion 20, a plurality of small blades 19 are provided upright at equal intervals. These small blades 19 are made of a semi-cylindrical thin plate, and their upper edges are juxtaposed in an arc shape corresponding to the shape of the inner wall surface of the outer blade 3. In this way, the inner blade 8 has an arc shape corresponding to the outer blade 3 as a whole, and the individual small blades 19 are fixed at right angles to the inner wall of the corresponding outer blade 3. That is, as shown in FIG. 1, the small blades 19 are arranged in a fan shape toward the center of the arc of the outer blade 3.
【００１４】 従って、内刃８が外刃３に弾接しつつその内壁に沿って往復摺動したとき、各 小刃１９のエッジは常に外刃３の内壁面に対して直角に位置し、外刃３の切刃孔 より導入された髭は確実に切断される。切断された髭は、枠部２０と外刃３間の 間隙及び枠部２０内の孔２０’より本体１の隔壁６上に落ちる。２２は隔壁６の 開孔７に嵌合したカバーパッキンである。Therefore, when the inner blade 8 elastically contacts the outer blade 3 and reciprocally slides along the inner wall of the outer blade 3, the edge of each small blade 19 is always positioned at a right angle to the inner wall surface of the outer blade 3, and The beard introduced through the cutting hole of the blade 3 is surely cut. The cut beard falls on the partition wall 6 of the main body 1 through the gap between the frame 20 and the outer cutter 3 and the hole 20 ′ in the frame 20. Reference numeral 22 is a cover packing fitted in the opening 7 of the partition wall 6.
【００１５】[0015]
