Description

本発明は、安全かみそりに係り、特に刃ユニットが取り付けられる柄によりシェービングされる皮膚の面に沿って動く切り刃縁を有する少なくとも一枚の刃を備える安全かみそり刃ユニットに関する。刃ユニットは、必要なときはユニットを新しい刃ユニットに取り替えできるように柄に取り付けられている。置換できる刃ユニットは通常カートリッジと言われている。また刃ユニットは、一枚又は複数枚の刃が鈍くなったときカミソリ全体を廃棄する意図で柄に永久に取り付けられる。かみそりの刃ユニットは、全般的に刃の前後で皮膚とそれぞれ接触するガード又はキャップ面を有しており、この面はいわゆるシェービング形状を達成するという重要な役割、即ちシェービング中皮膚に対する刃の方向付け及び位置を決めるパラメータという重要な役割をしている。
従来安全かみそりに、刃先の前で皮膚と接触する櫛状の構体を具備する提案があり、この構体はある場合にはガード面に配設され又はガード面を構成するようになっており、一方他の配置では一対の縦に並んだ刃間のスペーサに櫛構体を包括するようになっていた。櫛構体は一方で安全と快適という問題のバランスを保ち、他方で緻密なシェービングを成すために提供された。櫛構体の従来例として米国特許第3,004,337号、4,272,885号、5,359,774号に記載されており、それらには皮膚と刃先との間の接触を減少することで改良した安全と快適さが得られることが示されている。
櫛構体を有する従来の刃ユニットは、固定刃を備えており、シェービング形状を変更するため、シェービング中遭遇する力の下で刃が動くように取り付けられている刃ユニットに適応するために簡単に対応することは困難であった。
本発明によれば、安全かみそり刃ユニットはガードとキャップ面を有するフレームと、該ガードとキャップ面間のフレームに取り付けられたほぼ並行の刃先を有する複数本の刃とを備え、該刃はシェービング中に刃に懸かる力によりシェービング形状を変更するためフレーム内に独立して動くように各刃支持体に支持され、少なくとも刃支持体は、刃支持体に支持された刃に沿って離間した素子に強固に接続され且つ刃先の前方に突出し、該素子は刃の直前で且つ刃先にほぼ正接で皮膚と接触するための皮膚接触部分を有している。
従来の櫛構体を有する刃ユニットにおいて、安全性並びに快適性を改善する試みがあったが最高の緻密性が得られなかった。本発明による安全かみそり刃ユニットの可とする実施形態では、優れた緻密性が得られるだけでなく、安全性並びに快適性を高める利点も更に備えている。好ましい実施形態では前方に突出する素子は、その側面が0.10乃至0.30mmの範囲の距離、刃先から離間した点に直線上に延びる上面部分を有している。突出する素子は、刃支持体に強固に固着された部材に形成することもできるが、刃支持体と一体で有ることが好ましい。何れの場合も素子は可動の刃を有する刃ユニットに簡易に且つ都合良く組み込むことができ、素子はシェービング中に生ずる刃の移動にも拘わらず効果的に保たれる。更に素子は全ての場合刃先に密接する皮膚接触面を有する。平坦又はアーチ状の上面部分が刃先とほぼ共通面に有ることによって、素子は皮膚面を摺動するときスキー又はランナーと同様な様子で作動する傾向にあり、それにより刃が、刃先の長手方向に変位する傾向を阻止すると同時に刃を皮膚と効果的に接触するよう案内できる。
好ましい構造では突出素子は平坦な側部と、該平坦な側部に延び湾曲状の又は次第に広がる横腹面と滑らかに合体する上面部分の横方向縁を具備する。かかる特徴は素子の有効性に寄与すると共に快適性を保持できる。
素子の適切な幅は0.1乃至0.3mmの範囲であり、上部皮膚接触面部分の幅は0.1mm以下であり、素子が毛を皮膚面に対し平らに寝かせる傾向を回避できる。
素子は2mm以下例えば0.5乃至1.5mmの範囲のピッチで配設されることが好ましく、ほぼ1.0mmのピッチが特に適切である。
素子と皮膚面との間に穏和な最初の接触を得るため、その前端に円い鼻部を設けることもでき、この鼻部は上面部分に滑らかに導かれる。

図１に示すように、安全かみそり刃ユニット即ちカートリッジは、ガード及びキャップ面が設けられ且つ長手方向のフィンを持ったエラストマー材料のストリップ２と潤滑剤のストリップ３がをそれぞれ取り付けられたモールドプラスチックフレーム１を備えている。ガードとキャップの間には３枚の並列の刃４があり、刃はガードとキャップの間にシリースに配設された前方を向く切り刃縁を備えている。各刃４は刃支持体５に固着され、刃支持体の端部はそれ自体周知であるようにばね（図示せず）の作用に対して且つシェービング中刃に加わる力の下でフレームに対して刃を移動できるようにフレームに連結されている。
図２乃至４に詳細に示すように、各刃支持体５は全体的に直立のビーム部分１０を有し、その上端から前方上方に傾斜した刃プラットホーム１１が延び、その上面に例えばスポット溶接で刃４が固着されている。刃プラットホームから一様に離間し前方に突出して設けられた櫛素子１２は、刃先と垂直である。刃支持体上の櫛素子１２の形成は、その形状、位置及び寸法と共に本発明の重要な新規な特徴である。図示するように素子１２は、少なくとも刃先の前方に突出する区分に沿って側面は平坦であり、且つ素子は湾曲状の端部１５により側面に結合される平坦な上面部分１４を有する。上面部分１４の前方に位置する素子１２の先端は面部分１４に滑らかに導かれる円い鼻部１６を有する。素子１２の根部１７は、刃４の下面で縁の面に密接するため刃プラットホーム面よりより急峻に傾斜している上面を有するが、このことは必須要件ではなく、刃の下面と素子の間に大きな間隔があっても良い。上面部分１４の後部即ち尾端は刃先に近接しており、その間の間隙幅は、刃先から面部分１４の前方即ち先導端間での距離Ａ（図３）より数倍小さい。刃支持体の全ての素子の面部分１４は、正接の共通面即ち支持体を支持する刃先を含む面に置かれる。距離Ａは0.1mm乃至0.3mmの範囲、特に0.15mm乃至0.2mmの範囲である。この平坦な横方向の面間の素子の幅は0.5mm乃至1.5mmの範囲、例えば約1.0mmであり、素子は1.0mmピッチで配設される。
刃支持体の突出素子１２を使用することにより、刃先に垂直な方向に皮膚の上を動かすため刃ユニットに影響を与える案内効果があり、素子は皮膚に同様な方法で働き即ち皮膚面上を摺動する。これにより向上された安全と快適さが得られる。同時に素子１２は皮膚面と刃の効果的な共同作用を生み爽快感という言葉のように優れたシェービングを得ることができる。
図５乃至図９に、図１の安全かみそりユニットの一つ以上の刃の何れか一つに使用できる変形した刃支持体を示す。変形した刃支持体は図２乃至４に記載したものと同様であるが、前方突出素子２２の形状が異なる。平坦な上面部分を持つ代りに、素子は約0.07mmの曲率半径を持つアーチ状中央上面部分２４を有し、その横方向縁は平坦な側面に延びる次第に広がる横腹面２５に滑らかに合体される。図９の側面図で示すように、アーチ状上面部分の頂上は直線的に点２７まで延び、その点でこの面部分は円い鼻部２６と滑らかに合体する。素子２２の寸法は幅及びピッチに関する限り図２乃至４に記載したものと同じで、刃が刃支持体に取り付けられたとき、刃先から点２７の距離は前述のように距離Ａと同じである。図１０乃至１２に示す安全かみそりと刃支持体は、図１乃至９の実施形態のように刃支持体と一体化されている代わりに、刃先の前方に突出する素子３２が刃支持体３１に固着される分離した射出モールドプラスチック部材３０に形成されている。図示するようにモールド部材３０は、刃支持体に設けられた対応する穴３５を介して挿入される一体の杭即ちスタッド３４が長手方向に沿って離間して設けられ、スタッドの突出する自由端は例えば加熱加圧により変型され、刃支持体の後部に半径方向に拡大し、モールド体を刃支持体に緊着できる。モールド部材の上部縁は、刃３６を支持する部分の下側の刃支持体の外形に応ずるように形成され、素子３２はこの上部縁から前方に突出する。モールド部材３０の後端上面は、刃支持体３１と接触する二つの面を画定し、突出体が刃支持体と更には刃３６の切り刃縁と正確に配列することを支援する。突出体３２は図５乃至９で説明した刃支持体の素子２２と同様な形状並びに寸法を有しており、前述の実施形態に関して述べたように刃３６の鋭利な先に関して好ましく配設される。図１０乃至１２の刃及び支持体は図１の安全かみそりユニットの一つより以上の刃と支持体として使用できる。
本発明の変形並びに変更は本発明の精神並びに請求の範囲内で成すことができ、しかしながら我々の意図としては添付請求の範囲のみにより制限される。The present invention relates to a safety razor, and more particularly to a safety razor blade unit comprising at least one blade having a cutting edge that moves along the surface of the skin shaved by a handle to which the blade unit is attached. The blade unit is attached to the handle so that the unit can be replaced with a new blade unit when needed. The replaceable blade unit is usually called a cartridge. The blade unit is permanently attached to the handle with the intention of discarding the entire razor when one or more blades become dull. A razor blade unit generally has a guard or cap surface that makes contact with the skin before and after the blade, respectively, which plays an important role in achieving a so-called shaving shape, ie the direction of the blade relative to the skin during shaving. It plays an important role as a parameter that determines the position and position.
Conventionally, a safety razor has been proposed to have a comb-like structure that comes into contact with the skin in front of the cutting edge. In some cases, this structure is arranged on the guard surface or constitutes the guard surface. In other arrangements, a comb structure is included in a spacer between a pair of vertically arranged blades. The comb structure was provided to balance the problem of safety and comfort on the one hand, and on the other hand to create a dense shaving. Prior art examples of comb structures are described in U.S. Pat. It is shown.
A conventional blade unit with a comb structure has a fixed blade and is easy to adapt to a blade unit that is mounted so that the blade moves under the forces encountered during shaving to change the shaving shape. It was difficult to respond.
According to the present invention, the safety razor blade unit comprises a frame having a guard and a cap surface, and a plurality of blades having substantially parallel cutting edges attached to the frame between the guard and the cap surface, the blade being shaved. An element which is supported by each blade support so as to move independently in the frame to change the shaving shape by the force applied to the blade, and at least the blade support is separated along the blade supported by the blade support And has a skin contact portion for contacting the skin immediately in front of the blade and substantially tangentially to the blade edge.
In the conventional blade unit having a comb structure, there has been an attempt to improve safety and comfort, but the highest density has not been obtained. The possible embodiment of the safety razor blade unit according to the present invention not only provides excellent precision, but also has the advantage of increasing safety and comfort. In a preferred embodiment, the forward projecting element has a top surface that extends linearly at a point whose side is spaced from the cutting edge by a distance in the range of 0.10 to 0.30 mm. The protruding element can be formed on a member firmly fixed to the blade support, but it is preferable that the protruding element is integral with the blade support. In either case, the element can be easily and conveniently incorporated into a blade unit having a movable blade, and the element is effectively maintained despite the blade movement that occurs during shaving. Furthermore, the elements all have a skin contact surface that is in intimate contact with the cutting edge. By having a flat or arched upper surface portion approximately in common with the cutting edge, the element tends to operate in a manner similar to a ski or runner when sliding on the skin surface, so that the blade is in the longitudinal direction of the cutting edge. The blade can be guided to make effective contact with the skin at the same time as preventing the tendency to displace.
In a preferred construction, the projecting element comprises a flat side and a lateral edge of the top portion that smoothly mates with a curved or gradually expanding lateral belly surface extending to the flat side. Such features contribute to the effectiveness of the device and can maintain comfort.
The appropriate width of the element is in the range of 0.1 to 0.3 mm, and the width of the upper skin contact surface portion is 0.1 mm or less, thereby avoiding the tendency of the element to lay the hair flat against the skin surface.
The elements are preferably arranged with a pitch of 2 mm or less, for example in the range of 0.5 to 1.5 mm, with a pitch of approximately 1.0 mm being particularly suitable.
In order to obtain a gentle initial contact between the element and the skin surface, a round nose can also be provided at its front end, which is smoothly guided to the upper surface part.
The foregoing or other features of the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1, a safety razor blade unit or cartridge has a molded plastic frame provided with a strip 2 of elastomeric material and a lubricant strip 3 provided with guards and cap surfaces and having longitudinal fins, respectively. 1 is provided. There are three parallel blades 4 between the guard and the cap, and the blade is provided with a cutting blade edge facing the front disposed in the series between the guard and the cap. Each blade 4 is secured to a blade support 5 and the end of the blade support is against the frame under the action of a spring (not shown) and under the force applied to the blade during shaving as is known per se. It is connected to the frame so that the blade can be moved.
As shown in detail in FIGS. 2 to 4, each blade support 5 has an upright beam portion 10 as a whole, and a blade platform 11 inclined forward and upward from its upper end extends from the upper surface thereof, for example, by spot welding. The blade 4 is fixed. The comb element 12 provided uniformly spaced from the blade platform and protruding forward is perpendicular to the blade tip. The formation of the comb element 12 on the blade support is an important novel feature of the present invention along with its shape, position and dimensions. As shown, the element 12 is flat on the side along at least a section protruding forward of the cutting edge, and the element has a flat top portion 14 that is joined to the side by a curved end 15. The tip of the element 12 positioned in front of the upper surface portion 14 has a round nose 16 that is smoothly guided to the surface portion 14. The root portion 17 of the element 12 has an upper surface that is inclined more steeply than the blade platform surface in order to be in close contact with the edge surface at the lower surface of the blade 4, but this is not a requirement and is not a requirement. There may be large intervals in The rear or tail edge of the upper surface portion 14 is close to the blade edge, and the gap width therebetween is several times smaller than the distance A (FIG. 3) from the blade edge to the front of the surface portion 14 or the leading edge. The face portions 14 of all elements of the blade support are placed on a tangential common surface, i.e. the surface containing the cutting edge that supports the support. The distance A is in the range of 0.1 mm to 0.3 mm, particularly in the range of 0.15 mm to 0.2 mm. The width of the element between the flat lateral surfaces is in the range of 0.5 mm to 1.5 mm, for example about 1.0 mm, and the elements are arranged at a pitch of 1.0 mm.
By using the protruding element 12 of the blade support, there is a guiding effect that affects the blade unit in order to move it over the skin in a direction perpendicular to the blade edge, the element acting in a similar way on the skin, i.e. on the skin surface. Slide. This provides improved safety and comfort. At the same time, the element 12 produces an effective joint action between the skin surface and the blade, and an excellent shaving can be obtained as the word “exhilaration”.
FIGS. 5-9 illustrate a modified blade support that can be used with any one or more blades of the safety razor unit of FIG. The deformed blade support is the same as that described in FIGS. 2 to 4, but the shape of the forward projecting element 22 is different. Instead of having a flat top surface portion, the element has an arcuate central top surface portion 24 with a radius of curvature of about 0.07 mm, the lateral edges of which are smoothly merged into a gradually expanding lateral belly surface 25 extending to the flat side surface. . As shown in the side view of FIG. 9, the top of the arched upper surface portion extends linearly to point 27, at which point the surface portion smoothly merges with the round nose 26. The dimensions of the element 22 are the same as described in FIGS. 2-4 as far as the width and pitch are concerned, and when the blade is attached to the blade support, the distance from the blade tip to the point 27 is the same as the distance A as described above. . The safety razor and the blade support shown in FIGS. 10 to 12 are integrated with the blade support as in the embodiment of FIGS. 1 to 9, and an element 32 protruding forward of the blade tip is provided on the blade support 31. It is formed on a separate injection mold plastic member 30 to be secured. As shown in the figure, the mold member 30 is provided with integral piles or studs 34 inserted through corresponding holes 35 provided in the blade support so as to be spaced apart along the longitudinal direction, and the free end from which the stud protrudes. Can be deformed, for example, by heating and pressurizing, radially expanding at the rear of the blade support, and the mold body can be fastened to the blade support. The upper edge of the mold member is formed to conform to the outer shape of the lower blade support that supports the blade 36, and the element 32 projects forward from the upper edge. The upper surface of the rear end of the mold member 30 defines two surfaces that contact the blade support 31 and assists in accurately aligning the protrusion with the blade support and further with the cutting edge of the blade 36. The protrusion 32 has the same shape and dimensions as the blade support element 22 described in FIGS. 5-9 and is preferably disposed with respect to the sharp tip of the blade 36 as described with respect to the previous embodiment. . The blades and supports of FIGS. 10-12 can be used as more than one blade and support of the safety razor unit of FIG.
Variations and modifications of the invention can be made within the spirit and scope of the invention, but our intent is limited only by the scope of the appended claims.
