Description
本発明は、剃刀刃の剃圧を自在に調整することができる剃圧調整機構付き電気振動カミソリに関する。 The present invention relates to an electric vibration razor with a shaving pressure adjustment mechanism that can freely adjust the shaving pressure of a razor blade.
髭や髪、あるいは皮膚の表面の体毛を除去するための刃物としてカミソリがあり、カミソリは老若男女を問わず、身だしなみを整えるために広く一般に使用されている。近年においては三枚刃や四枚刃等といった非常に薄い鋼製の刃を複数並べて切れ味を向上させている製品が主流となっているが、大別すると、これらの複数枚刃と柄を一体化させた簡易構造の使い捨てタイプと、複数枚刃をプラスチックで固定したカートリッジ式の交換タイプに分かれている。特に、出張先や旅行先のホテル等で提供される髭剃用のカミソリは、コスト等の問題から、刃と柄を一体化とした使い捨てタイプが多く、全体デザインも機能も簡素化されている。これに対し、カートリッジ式の交換タイプでは、首振りヘッド機構を備えているものが多い。 There is a razor as a blade for removing wrinkles, hair, or body hair on the surface of the skin, and the razor is widely used for adjusting the appearance of both men and women. In recent years, products that improve the sharpness by arranging multiple extremely thin steel blades, such as three blades and four blades, have become the mainstream. It is divided into a disposable type with a simplified structure and a cartridge type exchange type in which multiple blades are fixed with plastic. In particular, shaving razors provided at business trip destinations and travel destination hotels are often disposable types with integrated blades and handles due to cost issues, and the overall design and functions are simplified. . On the other hand, many cartridge-type replacement types are provided with a swing head mechanism.
このような従来製品において、髭剃り時に使用されるカミソリの剃圧を調整するために、カミソリヘッド部と持ち手部のあいだに柔軟部材を設け、その素材の弾性力によって肌面に当たるカミソリ刃の剃圧を調整する方法が提案されている。例えば、棒状を成すハンドル部と、該ハンドル部の先端に連接した棒状のヘッド部と、該ヘッド部に沿って取り付けた剃刃を備え、前記ハンドル部およびヘッド部を可撓性材料で構成した「携帯用かみそり」（特許文献１参照）が提案され、公知技術となっている。 In such a conventional product, in order to adjust the shaving pressure of the razor used at the time of shaving, a flexible member is provided between the razor head part and the handle part, and the razor blade that hits the skin surface by the elastic force of the material is provided. A method for adjusting the shaving pressure has been proposed. For example, a handle portion having a rod shape, a rod-shaped head portion connected to the tip of the handle portion, and a razor blade attached along the head portion, and the handle portion and the head portion are made of a flexible material. "Portable razor" (see Patent Document 1) has been proposed and is a known technique.
また、弾性接続部材をハンドルと刃ユニットとの間で弧状ラインに形成し、刃ユニットを固定することができる端部で少なくても１つの刃が弾性接続部材の弧状ラインの接線にほぼ直角平面に配置されるように弾性接続部材に固定することができる「使い捨てカミソリ」（特許文献２参照）が提案され、公知技術となっている。 Further, the elastic connecting member is formed in an arcuate line between the handle and the blade unit, and at least one blade at the end where the blade unit can be fixed is a plane substantially perpendicular to the tangent line of the arcuate line of the elastic connecting member. A “disposable razor” (see Patent Document 2) that can be fixed to an elastic connecting member so as to be disposed in the art has been proposed and has become a publicly known technique.
また、携帯用のＴ字型振動カミソリであって、バッテリー接続端子が備えられたホルダーと、該ホルダーの上方に取り付けられる振動発生装置が付設された弾性部材で形成された連結柄と、該「連結柄へ連結するための連結部を下方に有する着脱自在のＴ字型替刃ユニットと、からなる本出願人による「携帯用Ｔ字型振動カミソリ器」（特許文献３参照）が提案され、公知技術となっている。 A portable T-shaped vibration razor comprising a holder provided with a battery connection terminal, a connecting handle formed by an elastic member provided with a vibration generating device attached above the holder, A "portable T-shaped vibratory razor" (see Patent Document 3) proposed by the present applicant, comprising a detachable T-shaped replaceable blade unit having a connecting portion for connecting to a connecting handle below, It is a known technique.
しかしながら、それらの提案の何れも、連結部に弾性部材を設け、その弾性部材の弾性力によってカミソリ刃を剃圧する方法を採っているため、使用される弾性部材の変形度合いの範囲内での剃圧力に限定され、使用者の好みや肌合いに合った剃圧調整ができない問題があった。 However, since all of these proposals employ a method in which an elastic member is provided in the connecting portion and the razor blade is shaved by the elastic force of the elastic member, the shaving within the range of deformation of the elastic member used is employed. There is a problem that the shaving pressure cannot be adjusted according to the user's preference and skin condition.
また、近年では、電気的に微小な振動を発生させるＴ字型の振動カミソリも多数のメーカーから製造販売されている。これらは、微小振動をカミソリに与えて髭等を立たせることにより、剃刀性の向上を図ることを目的としたものや、剃刀時の肌への滑らか感を与えることを主たる目的としているものである。しかし、係る電気振動カミソリは、発生させた振動の強さやサイクルを調整することができても、剃刀部位に押しつけたカミソリヘッド部の剃圧を調整することができないため、肌の弱い人が使用すると、その振動がダイレクトに肌に押しつけられることにより髭剃り負けを起こして肌を傷つけ、剃刀部位から出血してしまうという問題がある。係る問題を回避する手段として、振動部とカミソリ部のあいだに柔軟な素材を介在させることが考えられるが、単純に、振動部とカミソリ部のあいだに柔軟材料を介して接続すると、その材質によっては振動伝達を抑え過ぎてしまい、振動源から伝える振動力を低減してしまい、前記電気振動カミソリの目的を達成できなくなってしまう。即ち、微振動による前記効果を維持しつつ、必要以上の剃圧がかかった時はそれを逃がすことができる技術が求められているといえる。 In recent years, T-shaped vibration razors that generate electrical minute vibrations are also manufactured and sold by many manufacturers. These are mainly intended to improve the razor performance by giving a razor to the razor to make a heel stand, and to give a smooth feeling to the skin when razor. is there. However, even if the electric vibration razor can adjust the intensity and cycle of the generated vibration, it cannot adjust the shaving pressure of the razor head pressed against the razor part, so it is used by people with weak skin. Then, there is a problem that the vibration is directly pressed against the skin, causing shave loss and hurting the skin and bleeding from the razor site. As a means for avoiding such a problem, a flexible material may be interposed between the vibrating part and the razor part, but if a simple connection is made between the vibrating part and the razor part via a flexible material, depending on the material This suppresses vibration transmission excessively, reduces the vibration force transmitted from the vibration source, and cannot achieve the purpose of the electric vibration razor. That is, it can be said that there is a demand for a technique capable of escaping a shaving pressure more than necessary while maintaining the above-described effect due to microvibration.
そこで、本出願人は、前記種々の問題を解決すべく、持ち手部となる本体部と剃刀部間の距離と素材の関係、及び振動部とカミソリ部間の振動伝達状態に着目し、物質の持つ固有振動数と加振力の振動数をコントロールし、振動現象の共振や減衰等を考慮しながら、発生した微振動を上手く利用すれば、弾性部材の持つ弾性力による剃り圧調整を可能とすることのみならず、バイブレーション機構から得られる微振動の振幅を減衰させることなく、有効に剃刀部に振動を与えることができるのではないかとの着想の下、本発明に至ったものである。 Therefore, in order to solve the various problems, the present applicant pays attention to the relationship between the distance between the main body part and the razor part, which is the handle part, and the material, and the vibration transmission state between the vibration part and the razor part, By controlling the natural frequency and vibration frequency of the vibration force and taking into account the resonance and damping of vibration phenomena, it is possible to adjust the shaving pressure by the elastic force of the elastic member if it is used well The present invention has been achieved under the idea that vibration can be effectively applied to the razor portion without attenuating the amplitude of the fine vibration obtained from the vibration mechanism. .
本発明は、上記問題点に鑑み、剃刀刃の剃圧を自在に調整することができる剃圧調整機構付き電気振動カミソリの提供を図る。 In view of the above problems, the present invention aims to provide an electric vibration razor with a shaving pressure adjustment mechanism that can freely adjust the shaving pressure of a razor blade.
本発明は、カミソリ刃の剃圧を自在に調整することができる剃圧調整機構付き電気振動カミソリであって、Ｔ字型湿式シェーブカミソリの持ち手部を挟持するための挿入口及び挿入穴が設けられた弾性力を有する可撓性部材で形成される挟持部と、電動式バイブレーション機構を内蔵する本体部とから成り、前記挟持部と前記本体部とは、スライド機構を介して摺動可能に連結し、前記本体部に対する前記挟時部の突き出し量を調整可能としたことを特徴とする剃圧調整機構付き電気振動カミソリとした。 The present invention is an electric vibration razor with a shaving adjustment mechanism that can freely adjust the shaving pressure of a razor blade, and has an insertion port and an insertion hole for sandwiching a handle portion of a T-shaped wet shave razor. It consists of a clamping part formed of a flexible member having elasticity and a main body part that incorporates an electric vibration mechanism, and the clamping part and the main body part are slidable via a slide mechanism. The electric vibration razor with a shaving pressure adjusting mechanism is characterized in that the protruding amount of the clamping portion relative to the main body portion can be adjusted.
また、本発明は、前記挟持部をダブルモールド成形により弾性係数の異なる二種以上の可撓性部材で一体形成し、該挟持部の素材構成が、前記挿入口に向かうに従って、弾性係数の小さい可撓性部材よりも弾性係数の大きい可撓性部材が断面比において大きくなっていく構成を採用していることを特徴とする前記記載の剃圧調整機構付き電気振動カミソリとすることもできる。 Further, according to the present invention, the sandwiching portion is integrally formed of two or more types of flexible members having different elastic coefficients by double molding, and the material configuration of the sandwiching portion has a smaller elastic coefficient as it goes to the insertion port. The above-described electric vibration razor with a shaving pressure adjusting mechanism may be employed, in which a flexible member having a larger elastic coefficient than that of the flexible member is increased in cross-sectional ratio.
また、本発明は、前記挟持部において、Ｔ字型湿式シェーブカミソリの持ち手部を固定するための固定具を一以上備えたことを特徴とする前記剃圧調整機構付き電気振動カミソリとすることもできる。 Further, the present invention provides the electric vibration razor with a shaving pressure adjusting mechanism, wherein the clamping portion includes at least one fixture for fixing a handle portion of the T-shaped wet shave razor.

本発明の剃圧調整機構付き電気振動カミソリによれば、剃圧を調整する機構として、本体に対して挟時部の突き出し量を調整するという簡易な構造を採用したことで、使い勝手が良い上に軽量化ならびに製造コストの低廉が図れるという優れた効果を奏する。 According to the electric vibration razor with a shaving pressure adjusting mechanism of the present invention, as a mechanism for adjusting the shaving pressure, a simple structure that adjusts the protruding amount of the clamping portion with respect to the main body is adopted, so that it is easy to use. In addition, an excellent effect is achieved in that the weight can be reduced and the manufacturing cost can be reduced.
本発明の剃圧調整機構付き電気振動カミソリによれば、物質の持つ固有振動数と加振力の振動数をコントロールし、振動現象の共振と減衰を上手く利用できる構成を採用したことで、弾性部材の持つ弾性力による剃圧調整を可能とすることのみならず、バイブレーション機構から得られる振幅の減衰を抑えて、有効に剃刀部に振動を与えることができるという優れた効果を奏する。 According to the electric vibration razor with a shaving pressure adjustment mechanism of the present invention, by adopting a configuration that can control the natural frequency of the substance and the vibration frequency of the excitation force, and can effectively use the resonance and damping of the vibration phenomenon, Not only can the shave pressure be adjusted by the elastic force of the member, but also the vibration can be effectively applied to the razor part by suppressing the attenuation of the amplitude obtained from the vibration mechanism.
本発明の剃圧調整機構付き電気振動カミソリ１は、Ｔ字型湿式シェーブカミソリ１０の持ち手部１２を挟持するための挟持部２０に弾性力を有する可撓性部材で形成したことと、これを電動式バイブレーション機構３３を内蔵した本体部３０にスライド機構４０を介して摺動可能に連結させて、該本体部３０に対する該挟時部２０の突き出し量を調整可能とする構成を採用したことで、高い剃刀性を発揮させると共に、カミソリ負けをしないように肌を保護できることを最大の特徴とする。以下、実施例を図面に基づいて説明する。 The electric vibration razor 1 with a shaving pressure adjusting mechanism of the present invention is formed of a flexible member having elasticity in the holding part 20 for holding the handle part 12 of the T-shaped wet shave razor 10, and Is configured to be slidably connected to the main body portion 30 including the electric vibration mechanism 33 via the slide mechanism 40 so that the protruding amount of the clamping portion 20 with respect to the main body portion 30 can be adjusted. The most important feature is that the skin can be protected so as not to lose the razor while exhibiting high razor properties. Embodiments will be described below with reference to the drawings.
なお、本実施例で示される剃圧調整機構付き電気振動カミソリ１の全体形状及び各部の形状は、下記に述べる実施例に限定されるものではなく、本発明の技術的思想の範囲内、即ち、同一の作用効果を発揮できる形状及び寸法の範囲内で変更することができるものである。 The overall shape and the shape of each part of the electric vibration razor 1 with a shaving pressure adjusting mechanism shown in the present embodiment are not limited to the embodiments described below, and are within the scope of the technical idea of the present invention, that is, These can be changed within a range of shapes and dimensions that can exhibit the same effects.

FIG. 2 (a) shows a state where the sandwiching portion 20 does not protrude from the main body portion 30, and FIG. FIG. 2C shows a state in which the clamping part 20 protrudes from the main body part 30, and FIG. 2C shows a handle of the T-shaped wet shave razor 10. The state where the portion 12 is shallowly held in the insertion hole 22 and the T-shaped wet shave razor 10 protrudes from the holding portion 20 is shown. FIG. 2D shows a state in which the main body portion 30 protrudes from the sandwiching portion 20.
本発明に係る剃圧調整機構付き電気振動カミソリ１は、Ｔ字型湿式シェーブカミソリ１０の持ち手部１２を挟持するための弾性力を有する可撓性部材で形成される挟持部２０と、電動式バイブレーション機構３３を内蔵する本体部３０とをスライド機構４０を介して摺動可能に連結したことで、前記本体部３０に対する前記挟時部２０の突き出し量の調整を可能とする構成を採用している。 An electric vibrating razor 1 with a shaving pressure adjusting mechanism according to the present invention includes a clamping portion 20 formed of a flexible member having an elastic force for clamping a handle portion 12 of a T-shaped wet shave razor 10, and an electric motor. Adopting a configuration that allows adjustment of the protruding amount of the clamping portion 20 with respect to the main body portion 30 by slidably connecting the main body portion 30 having the built-in type vibration mechanism 33 via the slide mechanism 40. ing.
挟持部２０は、Ｔ字型湿式シェーブカミソリ１０の剃刀刃１１に適度な剃圧をかけることが可能な、柔軟性と弾性を有する素材で形成する。例えば、エラストマー(elastomer)や発泡樹脂（foamed plastics）等の可撓性部材を用いるのが一般的といえる。しかし、使用環境を考慮すれば、水分による加水分解し易いものを避けるために、シリコンゴム(silicone rubber)など高い耐水性を有する合成樹脂素材を用いることが望ましい。但し、ウレタン樹脂やウレタンゴムなどのポリウレタンを用いる場合においては、反発弾性率や曲げ弾性率の関係から、復元力の小さな素材では、剃刀刃１１に適度な剃圧をかけられず、また、電動式バイブレーション機構３３により発生した微細振動を吸収してしまうことになる。そこで、挟持部２０には、該剃刀刃１１に適切に振動を伝えることができ、且つ、その振動による柔らかい剃り味感等を阻害することにならない素材とする。 The clamping part 20 is formed of a material having flexibility and elasticity that can apply an appropriate shaving force to the razor blade 11 of the T-shaped wet shave razor 10. For example, it is common to use a flexible member such as an elastomer or foamed plastics. However, in consideration of the usage environment, it is desirable to use a synthetic resin material having high water resistance such as silicon rubber in order to avoid those which are easily hydrolyzed by moisture. However, when polyurethane such as urethane resin or urethane rubber is used, due to the relationship between the resilience elastic modulus and the flexural modulus, the razor blade 11 cannot be applied with an appropriate shaving force with a material having a small restoring force. Fine vibrations generated by the vibration mechanism 33 are absorbed. Therefore, the sandwiching portion 20 is made of a material that can appropriately transmit vibration to the razor blade 11 and that does not hinder a soft shaving taste or the like due to the vibration.
また、挟持部２０は略筒状体で形成され、中心内部には、Ｔ字型湿式シェーブカミソリ１０の持ち手部１２を挿入するための挿入口２１及び挿入穴２２が設けられている。該挿入口２１の開口面積及び挿入穴２２の深さは、一般的な使い捨て用カミソリの持ち手部１２を挟持できる寸法とする。例えば、ザ・ジレツト・カンパニーから販売されているＧｉｌｌｅｔｔｅ（登録商標）ＣＵＳＴＯＭＰＬＵＳ（登録商標）ＥＸや、貝印株式会社から販売されているベスティ（登録商標）ＥＸなど、広く流通している一般的な使い捨て用のものでは、持ち手部１２の長さが８０ｍｍから１００ｍｍ程度で、縦横を其々１０ｍｍ程度の寸法としているものが多い。そこで、例えば、挿入口２１の断面形状を略正方形状とし、縦横寸法を其々８ｍｍ程度とし、成功挿入穴２２の穴の深さを１００ｍｍから１３０ｍｍとする。挿入口２１の断面形状を略正方形状とした場合は、Ｔ字型湿式シェーブカミソリ１０を、図に示した状態から９０度回転させて装着することも可能である。 Moreover, the clamping part 20 is formed in a substantially cylindrical body, and an insertion port 21 and an insertion hole 22 for inserting the handle part 12 of the T-shaped wet shave razor 10 are provided inside the center. The opening area of the insertion port 21 and the depth of the insertion hole 22 are set to dimensions that can hold the handle portion 12 of a general disposable razor. For example, Gillette (registered trademark) CUSTOMPLUS (registered trademark) EX sold by The Gillett Company and Vesti (registered trademark) EX sold by Kaiin Co., Ltd. In many cases, the length of the handle portion 12 is about 80 mm to 100 mm, and the length and width are about 10 mm each. Therefore, for example, the cross-sectional shape of the insertion port 21 is a substantially square shape, the vertical and horizontal dimensions are about 8 mm each, and the depth of the successful insertion hole 22 is 100 mm to 130 mm. When the cross-sectional shape of the insertion port 21 is a substantially square shape, the T-shaped wet shave razor 10 can be mounted by being rotated 90 degrees from the state shown in the figure.
また、挟持部２０には、本体部３０と摺動可能に接合させるためのスライド機構４０が底面部に設けられており、例えば、図２（ａ）に示すように、挟持部２０の底面部にＬ字状の凹溝を設け、これに対して組み合わされるＬ字状の凸溝とした場合であれば、挟持部２０のヘッド部１３側端部の位置Ｐ１から反対端部の位置Ｐ３のまでの長さＬ３を有する。 In addition, the holding part 20 is provided with a slide mechanism 40 for slidably joining to the main body part 30, for example, as shown in FIG. 2A, the bottom part of the holding part 20. If an L-shaped groove is provided in the L-shaped groove and the L-shaped groove is combined with the L-shaped groove, the position P1 from the end P1 side of the clamping unit 20 to the position P3 of the opposite end is changed. Length L3.
本体部３０は、内部に振動用モータ３１とバッテリー３２から構成される電動式振動機構３３を備え、上面には前記挟持部２０の底面部に設けられるＬ字状の凹溝に対応するＬ字状の凸溝を備える。該凸溝は、位置Ｐ１から所定の距離Ｌ１だけ離れた位置Ｐ２から始まり、反対端部Ｐ４のまでの長さＬ２を有する。なお、振動用モータ３１の出力軸に偏芯ウェイトを備えて振動を発生させる場合等では、該偏芯ウェイトが位置Ｐ２近くになるように配置し、発生した振動を効率よくカミソリヘッド部１３へ伝達させることが望ましい。 The main body 30 includes an electric vibration mechanism 33 including a vibration motor 31 and a battery 32 inside, and an L-shape corresponding to an L-shaped groove provided on the bottom surface of the clamping portion 20 on the top surface. A convex groove is provided. The convex groove has a length L2 starting from a position P2 that is a predetermined distance L1 away from the position P1 and extending to the opposite end P4. In the case where the output shaft of the vibration motor 31 is provided with an eccentric weight to generate vibration, the eccentric weight is disposed near the position P2, and the generated vibration is efficiently transmitted to the razor head unit 13. It is desirable to communicate.
第一実施例に係る剃圧調整機構５０は、図２に示すように、本体部３０と挟持部２０との突き出し量、及びＴ字型湿式シェーブカミソリ１０の挿入状態により剃刀部位や好みに応じて剃圧を調整する。具体的には、剃圧強さは位置Ｐ２を支点とした位置Ｐ１までの可撓性部材の長さと、位置Ｐ１からカミソリヘッド部１３の位置Ｐ５までの距離Ｌ４又は距離Ｌ５と、持ち手部１２の挿入深さにより変動する。可撓性部材の弾性力を最も作用させないようにするには、図２（ｄ）のように弾性力を作用させる位置Ｐ１から位置Ｐ２の距離Ｌ６のように短くし、持ち手部１２を挿入穴２２に深く挿入する。他方、剃圧を弱めたいのであれば、図２（ｃ）のような配置構成にすればよい。即ち、図２上では（ｄ）、（ａ）、（ｂ）、（ｃ）の順に剃圧は強い。なお、距離Ｌ４及び距離Ｌ５は、位置Ｐ１からカミソリヘッド部１３の位置Ｐ５までの長さであり、Ｔ字型湿式シェーブカミソリ１０の持ち手部１２が挿入穴２２へ挿入される深さによって変動する。係る距離Ｌ４から距離Ｌ５の挿入深さ調整は、使用するカミソリヘッド部１３の持つ固有振動数と加振力の振動数の関係から、共振等による異常な振動現象が起きた場合などに、該挿入深さを変えることによって調整する。 The shaving pressure adjusting mechanism 50 according to the first embodiment, as shown in FIG. 2, depends on the amount of protrusion between the main body portion 30 and the clamping portion 20 and the insertion state of the T-shaped wet shave razor 10 according to the razor site and preference. Adjust the shaving pressure. Specifically, the shaving strength includes the length of the flexible member from the position P2 to the position P1, the distance L4 or the distance L5 from the position P1 to the position P5 of the razor head portion 13, and the handle portion 12. Varies depending on the insertion depth. In order to minimize the elastic force of the flexible member, it is shortened as shown by a distance L6 from the position P1 to the position P2 where the elastic force is applied as shown in FIG. Insert deeply into hole 22. On the other hand, if it is desired to reduce the shaving pressure, an arrangement configuration as shown in FIG. That is, the shaving pressure is strong in the order of (d), (a), (b), and (c) on FIG. The distance L4 and the distance L5 are the lengths from the position P1 to the position P5 of the razor head portion 13, and vary depending on the depth at which the handle portion 12 of the T-shaped wet shave razor 10 is inserted into the insertion hole 22. To do. The insertion depth adjustment from the distance L4 to the distance L5 is performed when an abnormal vibration phenomenon due to resonance or the like occurs due to the relationship between the natural frequency of the razor head unit 13 to be used and the vibration frequency. Adjust by changing the insertion depth.
図３は、本発明の第二実施例に係る剃圧調整機構の説明図であり、図３（ａ）は、挟時部２０に対しＴ字型湿式シェーブカミソリ１０の持ち手部１２が挿入穴２２に深く挟持されている状態であって、挟持部２０と本体部３０とが突き出しの関係とならない状態を示している。また、図３（ｂ）は、挟時部２０に対し、Ｔ字型湿式シェーブカミソリ１０の持ち手部１２が挿入穴２２に深く挟持されているが、挟時部２０が本体部３０に対し突き出している状態を示している。図３（ｃ）は挟時部２０に対しＴ字型湿式シェーブカミソリ１０の持ち手部１２が挿入穴２２に浅く挟持させたときの状態を示している。 FIG. 3 is an explanatory view of the shaving pressure adjusting mechanism according to the second embodiment of the present invention. FIG. 3 (a) shows that the handle portion 12 of the T-shaped wet shave razor 10 is inserted into the sandwiching portion 20. A state in which the holding part 20 and the main body part 30 do not protrude is shown in a state where the holding part 20 is deeply held in the hole 22. In FIG. 3B, the handle portion 12 of the T-shaped wet shave razor 10 is deeply held in the insertion hole 22 with respect to the holding portion 20. The protruding state is shown. FIG. 3C shows a state in which the handle portion 12 of the T-shaped wet shave razor 10 is held shallowly in the insertion hole 22 with respect to the holding portion 20.
第２の実施形態における剃圧調整機構付き電気振動カミソリ１では、ダブルモールド成形により弾性係数の異なる二種以上の可撓性部材で挟持部２０を一体形成し、該挟持部２０の素材構成が、位置Ｐ２から位置Ｐ１の挿入口２１に向かうに従って、弾性係数の小さい可撓性部材よりも弾性係数の大きい可撓性部材が断面比において大きくなっていく構成を採用している。 In the electric vibration razor 1 with a shaving pressure adjusting mechanism in the second embodiment, the clamping part 20 is integrally formed by two or more flexible members having different elastic coefficients by double molding, and the material configuration of the clamping part 20 is as follows. A configuration is adopted in which the flexible member having a larger elastic coefficient becomes larger in sectional ratio than the flexible member having a smaller elastic coefficient as it goes from the position P2 to the insertion port 21 at the position P1.
第二実施例に係る剃圧調整機構５０では、図３に示すように、挟時部２０に対しＴ字型湿式シェーブカミソリ１０の持ち手部１２を挿入穴２２に深く挟持させた状態では、カミソリヘッド部１３に作用した剃圧により挟持部２０に作用する曲げ応力に対し、弾性係数の小さい可撓性部材５１よりも弾性係数の大きい可撓性部材５２が断面比において大きいため、係る曲げ応力に対する反発弾性力Ｍ２が大きく、カミソリヘッド部１３反り角Ｒは小さくなる。これに対し、持ち手部１２を挿入穴２２に浅く挟持させた状態では、カミソリヘッド部１３に作用した剃圧により挟持部２０に作用する曲げ応力に対し、弾性係数の大きい可撓性部材５２よりも弾性係数の小さい可撓性部材５１が断面比において大きいため、係る曲げ応力に対する反発弾性力Ｍ１が小さく、カミソリヘッド部１３反り角Ｒは大きくなる。即ち、挟持部２０に対する持ち手部１２の挿入状態により、剃刀部位や好みに応じて剃圧を調整する。 In the shaving pressure adjusting mechanism 50 according to the second embodiment, as shown in FIG. 3, in the state where the handle portion 12 of the T-shaped wet shave razor 10 is deeply held in the insertion hole 22 with respect to the holding portion 20, Since the flexible member 52 having a larger elastic coefficient than the flexible member 51 having a smaller elastic coefficient is larger in the cross-sectional ratio than the flexible member 51 having a smaller elastic coefficient with respect to the bending stress acting on the clamping part 20 due to the shaving pressure acting on the razor head part 13, The rebound elastic force M2 against stress is large, and the razor head portion 13 warp angle R is small. On the other hand, in a state where the handle portion 12 is shallowly held in the insertion hole 22, the flexible member 52 having a large elastic coefficient with respect to the bending stress acting on the clamping portion 20 due to the shaving pressure acting on the razor head portion 13. Since the flexible member 51 having a smaller elastic coefficient than the sectional ratio is large, the rebound elastic force M1 against the bending stress is small, and the warp angle R of the razor head portion 13 is large. That is, the shaving pressure is adjusted according to the razor part and the preference according to the insertion state of the handle portion 12 with respect to the sandwiching portion 20.
第三実施例に係る剃圧調整機構付き電気振動カミソリ１では、挟持部２おの上部に、Ｔ字型湿式シェーブカミソリ１０の持ち手部１１を固定するための固定具２３を一以上備えた構成を採用している。持ち手部１１をしっかりと保持すること、及び、使用するＴ字型湿式シェーブカミソリ１０によっては、持ち手部１１の断面形状が略長方形状のものなどにも挟持可能とするためである。具体的には、蝶ボルト等のおねじ螺合部材で挟持部２０の外側から押圧することにより持ち手部１１を保持する。この場合、柔軟な弾性部材で成形されている挟持部２０に直接めねじ等の螺合部を形成すると、該螺合部が崩れやすいため、金象又は硬質樹脂のヘリサートを用いることが望ましい。 In the electric vibration razor 1 with a shaving pressure adjusting mechanism according to the third embodiment, one or more fixing tools 23 for fixing the handle portion 11 of the T-shaped wet shave razor 10 are provided on the upper portion of the clamping portion 2. The configuration is adopted. This is because the handle portion 11 can be firmly held, and depending on the T-shaped wet shave razor 10 to be used, the handle portion 11 can be clamped even in a substantially rectangular shape. Specifically, the handle portion 11 is held by pressing it from the outside of the clamping portion 20 with a screw threaded member such as a butterfly bolt. In this case, it is desirable to use a metal elephant or a hard resin helisert because a screwed portion such as a female screw is formed directly on the pinching portion 20 formed of a flexible elastic member.
本発明の剃圧調整機構付き電気振動カミソリ１は、弾性力を有する可撓性部材で形成される挟持部と、電動式バイブレーション機構を内蔵する本体部とを、スライド機構を介して摺動可能に連結し、本体部に対する挟時部の突き出し量を調整することで、適度な押圧と振動を肌部等に与えることを可能としたことを特徴とするものであるため、歯ブラシや、美顔マッサージ具、ネイル研磨具、除去作業工具の柄等に応用することができるもので、本発明に係る剃圧調整機構付き電気振動カミソリ１の産業上の利用可能性は大きいものと思量される。 The electric vibration razor 1 with a shaving pressure adjusting mechanism according to the present invention can slide through a slide mechanism between a clamping portion formed of a flexible member having elasticity and a main body portion incorporating an electric vibration mechanism. It is possible to apply moderate pressure and vibration to the skin part etc. by adjusting the protruding amount of the pinching part with respect to the main body part. It can be applied to a tool, a nail polishing tool, a handle of a removal work tool, etc., and the industrial applicability of the electric vibration razor 1 with a shaving pressure adjusting mechanism according to the present invention is considered to be great.
