Description

本発明は、電気かみそりの本体部に装着されて、本体部を落下衝撃や衝突衝撃から守るための防護枠を備えている電気かみそりに関する。 The present invention relates to an electric razor that is attached to a main body portion of an electric razor and includes a protective frame for protecting the main body portion from a drop impact and a collision impact.

この種の電気かみそりは、例えば特許文献１に公知である。そこでは、防護枠を電気かみそりの本体部に組み付けて、不使用状態における外刃の外面を防護枠のキャップ部で覆うようにしている。防護枠は、本体部の前後面を覆う前後一対の保護壁と、保護壁の下端どうしを繋ぐキャップ部とでＵ字状に構成してある。一対の保護壁は、それぞれ本体部の前後面に設けた支軸部で回転自在に支持してあり、使用時と不使用時とで防護枠を１８０度回転操作することにより、ヘッド部を防護枠の上方に露出させ、あるいはヘッド部をキャップ部と正対させて外刃を保護できる。同様の防護枠を備えた電気かみそりは、特許文献２、３に公知であり、これらの電気かみそりおいては、本体部の左右側面を覆う左右一対の保護壁と、保護壁の下端どうしを繋ぐキャップ部、あるいは枠体とでＵ字状に構成してある。 This type of electric shaver is known, for example, from US Pat. In this case, the protective frame is assembled to the main body portion of the electric razor so that the outer surface of the outer blade when not in use is covered with the cap portion of the protective frame. The protective frame is configured in a U shape by a pair of front and rear protective walls that cover the front and rear surfaces of the main body and a cap that connects the lower ends of the protective walls. The pair of protective walls are rotatably supported by spindles provided on the front and back surfaces of the main body, and the head is protected by rotating the protective frame 180 degrees when used and when not used. The outer blade can be protected by exposing it above the frame or by making the head portion face the cap portion. Electric razors having the same protective frame are known in Patent Documents 2 and 3, and in these electric razors, a pair of left and right protective walls covering the left and right side surfaces of the main body and the lower ends of the protective walls are connected to each other. The cap part or the frame body is U-shaped.

本発明においては、ＬＥＤを光源にして透明な枠体を利用して発光表示を行なうが、類似する表示構造は特許文献４に見ることができる。そこでは、透明な表示板の側端にＬＥＤを配置し、表示板の内面から外面側へ向かって一群の表示穴を形成し、表示穴の内奥に傾斜面を設けて、表示光を傾斜面で表示板の外面へ向かって反射できるようにしている。 In the present invention, a light emitting display is performed using an LED as a light source and a transparent frame, and a similar display structure can be seen in Patent Document 4. There, LEDs are arranged on the side edges of the transparent display panel, a group of display holes are formed from the inner surface to the outer surface of the display panel, and an inclined surface is provided inside the display hole to tilt the display light. The surface can be reflected toward the outer surface of the display board.

特許文献１ないし特許文献３における防護枠によれば、不使用時の外刃の外面を防護枠で覆って、落下衝撃によって外刃（網刃）が破損するのを防止できる。しかし、外刃を保護するための防護枠であるため、本体部を保護する機能が充分ではなく、落下衝撃や衝突衝撃を受けるような場合に、本体部や防護枠、あるいは防護枠の軸支部分が破損するおそれがある。防護枠を本体部で回転自在に軸支するので、防護枠を回転操作する際などに、誤って指先を防護枠と本体部との間に挟むおそれがある。落下衝撃を受けて、防護枠が本体部と交差する姿勢に回動するおそれもある。 According to the protective frame in Patent Document 1 to Patent Document 3, it is possible to prevent the outer blade (mesh blade) from being damaged by a drop impact by covering the outer surface of the outer blade when not in use with the protective frame. However, since it is a protective frame for protecting the outer blade, the function to protect the main unit is not sufficient, and when it receives a drop impact or collision impact, the main unit, the protective frame, or the pivot support of the protective frame The minutes may be damaged. Since the protective frame is pivotally supported by the main body, there is a risk that a fingertip may be accidentally pinched between the protective frame and the main body when the protective frame is rotated. In response to the drop impact, there is a possibility that the protective frame may turn to a posture that intersects the main body.

電気かみそりの外形寸法は、ヘッド部および本体部の前後厚みや左右幅によって概ね決まるが、上記のように防護枠を付加した電気かみそりにおいては、防護枠の前後の保護壁や左右の保護壁の分だけ、電気かみそりの前後厚み寸法や左右幅寸法が大きくなってしまう。そのため、本体部を防護枠ごとつかむときのグリップ厚みやグリップ幅が大きくなるのを避けられず、使用者によっては本体部をしっかりと握り保持するのが困難になる。 The external dimensions of the electric razor are largely determined by the front and rear thicknesses and the left and right widths of the head and main body. However, in the case of an electric razor with a protective frame as described above, the protective walls before and after the protective frame and the left and right protective walls The front and rear thickness dimensions and the left and right width dimensions of the electric razor increase by the amount. For this reason, it is inevitable that the grip thickness and the grip width when the main body is held together with the protective frame are increased, and it becomes difficult for some users to hold and hold the main body firmly.

本発明の目的は、大きな落下衝撃や衝突衝撃受けるような場合でも、本体部を防護枠で確実に保護して、堅牢で耐久性に優れた電気かみそりを提供することにある。本発明の目的は、堅牢であるばかりでなく、シンプルなデザインで高級感に富む印象を醸し興趣を惹起できる電気かみそりを提供することにある。本発明の目的は、防護枠を備えているにもかかわらずつかみやすく、しかも本体部をしっかりと握り保持することができる、使い勝手に優れた電気かみそりを提供することにある。 An object of the present invention is to provide an electric shaver that is robust and excellent in durability by securely protecting a main body portion with a protective frame even when receiving a large drop impact or collision impact. An object of the present invention is to provide an electric shaver that is not only robust, but also has a simple design and a high-class impression, and can be interesting. SUMMARY OF THE INVENTION An object of the present invention is to provide an electric shaver that is easy to grasp despite having a protective frame and that is capable of firmly grasping and holding a main body and is excellent in usability.

図３に示すように、前ケース２５ａおよび後ケース２５ｂで構成される本体ケース２５の内部に内ケース２６を配置する。内ケース２６の内部に、モーター１４、電池２８、および回路基板２９を含む電装品ユニットを収容する。 As shown in FIG. 3, an inner case 26 is arranged inside a main body case 25 composed of a front case 25 a and a rear case 25 b. The electrical component unit including the motor 14, the battery 28, and the circuit board 29 is accommodated in the inner case 26.

内ケース２６とヘッド部２との間に、これら両者２・２６の隙間を塞ぐパッキン３４を配置する。パッキン３４の外面を本体ケース２５の上部で覆って保護する。 Between the inner case 26 and the head portion 2, a packing 34 that closes the gap between the two 2 26 is disposed. The outer surface of the packing 34 is covered and protected by the upper part of the main body case 25.

本発明では、一対の縦枠５３と、両縦枠５３の下端どうしを繋ぐ底枠５４とで防護枠３を構成し、両縦枠５３および底枠５４が本体部２に密接する状態で防護枠３を本体部２に装着固定して、本体部２を防護枠３で保護できるようにした。このように、防護枠３を本体部２に密着固定する電気かみそりによれば、大きな落下衝撃や衝突衝撃を受けるような場合に、外部から加わる衝撃を防護枠３で吸収して本体部２を保護することができる。したがって、主として外刃を保護するために設けられた従来の防護枠とは異なり、防護枠３によって本体部２の破損を確実に防止できる、堅牢さと耐久性に優れた電気かみそりを提供できる。また、防護枠３を本体部２に対して密着固定するので、本体部２と防護枠３とを同時につかみ、あるいは握り持つ状態において、防護枠３がぐらつくことがなく、持ちやすく扱いやすい電気かみそりとすることができる。 In the present invention, the protective frame 3 is constituted by a pair of vertical frames 53 and a bottom frame 54 that connects the lower ends of the vertical frames 53, and the vertical frame 53 and the bottom frame 54 are protected in close contact with the main body 2. The frame 3 is attached and fixed to the main body 2 so that the main body 2 can be protected by the protective frame 3. As described above, according to the electric razor for tightly fixing the protective frame 3 to the main body 2, when receiving a large drop impact or collision shock, the external shock is absorbed by the protective frame 3 and the main body 2 is held. Can be protected. Therefore, unlike the conventional protective frame provided mainly for protecting the outer blade, it is possible to provide an electric shaver excellent in robustness and durability that can reliably prevent the main body 2 from being damaged by the protective frame 3. In addition, since the protective frame 3 is firmly fixed to the main body 2, the electric shaver is easy to hold and handle without the wobbling of the protective frame 3 when the main body 2 and the protective frame 3 are held or held at the same time. It can be.

防護枠３の左右幅Ｌが本体部２の前後厚みＢ１に比べて大きく設定してあると、防護枠３と本体部２の横断面の外郭形状を、前後厚みが小さな扁平形状にすることができるので、図１２（ａ）に示すように、電気かみそりを親指と他の４指とで前後に挟み持つ状態において、本体部２を確実に前後に挟み持って、電気かみそりの姿勢を肌面に沿って的確に追随させることができる。また、本体部２を親指と他の４指とで前後に挟み持つとき、広幅の防護枠３の後面、または前面を指先や手の平で受け止め支持できるので、電気かみそりを常に安定した状態で挟み持って、使用者の意図どおりに電気かみそりの姿勢を変更することができる。 If the lateral width L of the protective frame 3 is set to be larger than the front-rear thickness B1 of the main body 2, the outer shape of the cross section of the protective frame 3 and the main body 2 may be made flat with a small front-rear thickness. As shown in FIG. 12 (a), in the state where the electric razor is held back and forth between the thumb and the other four fingers, the main body 2 is securely held back and forth, and the posture of the electric razor is changed to the skin surface. Can be followed accurately along. In addition, when the main body 2 is sandwiched between the thumb and the other four fingers, the rear or front of the wide protective frame 3 can be received and supported by the fingertips or palms, so that the electric razor is always held in a stable state. Thus, the posture of the electric razor can be changed as intended by the user.

左右一対の側枠５３と底枠５４とで防護枠３を逆門形に形成し、防護枠３の前後厚みＢ２を本体部２の前後厚みＢ１に比べて小さく設定すると、電気かみそりを親指と他の４指とで前後に挟み持つとき、防護枠３に邪魔されることもなく本体部２を確実に前後に挟み持つことができる。さらに、図１２（ｂ）に示すように、本体部２と防護枠３とを片手で握り持つ場合に、本体部２の前後面と防護枠３の左右側面の４個所を指や手の平に密着させて、手にフィットした状態で確りと握り締めることができ、全体として握りやすく扱いやすい電気かみそりとすることができる。 When the protective frame 3 is formed in a reverse portal shape with the pair of left and right side frames 53 and the bottom frame 54, and the front and rear thickness B2 of the protective frame 3 is set smaller than the front and rear thickness B1 of the main body 2, the electric razor When sandwiched between the other four fingers in the front-rear direction, the main body 2 can be reliably sandwiched in the front-rear direction without being obstructed by the protective frame 3. Furthermore, as shown in FIG. 12B, when holding the main body 2 and the protective frame 3 with one hand, the front and rear surfaces of the main body 2 and the left and right sides of the protective frame 3 are in close contact with the fingers and the palm. Thus, it is possible to make an electric razor that is easy to grasp and easy to handle as a whole.

前後に２分割された前ケース２５ａおよび後ケース２５ｂで本体ケース２５を構成し、これら前後ケース２５ａ・２５ｂを防護枠３に設けた係合部５７に係合して、本体ケース２５の上下方向および左右方向への移動を規制すると、本体部２と防護枠３とを強固に一体化できる。したがって、外部から加わる衝撃を防護枠３で吸収するとき、本体部２の一部に衝撃が集中し破損するのを防いで、防護枠３による保護機能をさらに確実に発揮できる。 The front case 25a and the rear case 25b divided into two in the front and rear form the main body case 25, and the front and rear cases 25a and 25b are engaged with the engaging portions 57 provided in the protective frame 3, so If the movement in the left-right direction is restricted, the main body 2 and the protective frame 3 can be firmly integrated. Therefore, when the shock applied from the outside is absorbed by the protective frame 3, the protective function by the protective frame 3 can be more reliably exhibited by preventing the shock from being concentrated on a part of the main body portion 2 and being damaged.

前後ケース２５ａ・２５ｂと係合部５７の外面に固定ピース８９を装着して、前後ケース２５ａ・２５ｂの前後方向の分離を阻止すると、外部から加わる衝撃によって前ケース２５ａ、あるいは後ケース２５ｂが防護枠３から分離するのを固定ピース８９で確実に阻止できる。したがって、本体部２と防護枠３とを強固に一体化して、防護枠３による保護機能をさらに強化できる。 If the front and rear cases 25a and 25b are fixed to the outer surfaces of the engaging portions 57 with the fixing pieces 89 to prevent the front and rear cases 25a and 25b from being separated in the front-rear direction, the front case 25a or the rear case 25b is protected by an external impact. Separation from the frame 3 can be reliably prevented by the fixed piece 89. Therefore, the main body 2 and the protective frame 3 can be firmly integrated to further strengthen the protection function of the protective frame 3.

防護枠３の側枠５３に係止凹部５６を備えた係合部５７を設け、前後ケース２５ａ・２５ｂに設けた係合突起３９・４５を係止凹部５６に係合して、本体ケース２５の上下方向および左右方向への移動を規制する係合構造によれば、側枠５３の上端に係合部５７を設けるだけでよいので、防護枠３の構造を簡素化して、その分だけ防護枠３の加工コストを削減できる。また、係合構造の構造をより簡素なものとしながら、本体ケース２５と防護枠３とを強固に連結し一体化できる。 An engaging portion 57 having a locking recess 56 is provided on the side frame 53 of the protective frame 3, and the engaging protrusions 39 and 45 provided on the front and rear cases 25 a and 25 b are engaged with the locking recess 56, so According to the engagement structure that restricts the movement of the frame in the vertical direction and the horizontal direction, it is only necessary to provide the engagement portion 57 at the upper end of the side frame 53. Therefore, the structure of the protection frame 3 is simplified, and the protection is made accordingly. The processing cost of the frame 3 can be reduced. Further, the main body case 25 and the protective frame 3 can be firmly connected and integrated while simplifying the structure of the engagement structure.

コ字状の固定ピース８９を、係合突起３９・４５の外面基端に設けたスリット９２に差し込み係合して、前後ケース２５ａ・２５ｂを前後方向へ分離不能に固定する係合構造によれば、前後ケース２５ａ・２５ｂに設けた係合突起３９・４５の外面を固定ピース８９で覆って、両係合突起３９・４５の分離移動を規制できる。したがって、外部から加わる衝撃によって、各係合突起３９・４５が係合部５７から抜け外れるのを固定ピース８９で確実に阻止して、本体ケース２５と防護枠３とをさらに強固に連結し一体化できる。 According to the engagement structure in which the U-shaped fixing piece 89 is inserted into and engaged with the slit 92 provided at the base end of the outer surface of the engagement protrusions 39 and 45 so that the front and rear cases 25a and 25b are fixed in a non-separable direction. For example, the outer surfaces of the engagement protrusions 39 and 45 provided on the front and rear cases 25a and 25b can be covered with the fixed piece 89, so that the separation movement of the engagement protrusions 39 and 45 can be restricted. Therefore, the fixing piece 89 reliably prevents the engagement protrusions 39 and 45 from being detached from the engagement portion 57 due to an external impact, and the main body case 25 and the protective frame 3 are more firmly connected and integrated. Can be

固定ピース８９の外面を、本体ケース２５に係合固定される化粧ピース６８で覆うと、固定ピース８９が電気かみそりの外面に剥き出しになるのを防いで、外部から加わる衝撃を化粧ピース６８で受け止めることができる。したがって、本体ケース２５と防護枠３の係合構造部分に加わろうとする衝撃を化粧ピース６８で受け止めて、固定ピース８９が衝撃を受けて前後ケース２５ａ・２５ｂから抜け外れるのを確実に防止できる。また、化粧ピース６８の係合片９４を前後ケース２５ａ・２５ｂの係合溝９５と係合し、さらに、一対の弾性係合爪１００を係合突起３９・４５に係合して、化粧ピース６８を本体ケース２５に分離不能に係合固定するので、化粧ピース６８が前後ケース２５ａ・２５ｂから分離するのを阻止できる。 When the outer surface of the fixed piece 89 is covered with the decorative piece 68 engaged and fixed to the main body case 25, the fixed piece 89 is prevented from being exposed to the outer surface of the electric razor, and the externally applied impact is received by the decorative piece 68. be able to. Therefore, it is possible to reliably prevent the fixed piece 89 from being detached from the front and rear cases 25a and 25b by receiving the impact that is about to be applied to the engaging structure portion of the main body case 25 and the protective frame 3 by the decorative piece 68. Further, the engaging piece 94 of the decorative piece 68 is engaged with the engaging grooves 95 of the front and rear cases 25a and 25b, and the pair of elastic engaging claws 100 are engaged with the engaging protrusions 39 and 45, thereby making the decorative piece. Since 68 is engaged and fixed to the main body case 25 in an inseparable manner, it is possible to prevent the decorative piece 68 from being separated from the front and rear cases 25a and 25b.

固定ピース８９と化粧ピース６８との間にスイッチボタン６６を配置すると、固定ピース８９が係合突起３９・４５から分離するのをスイッチボタン６６で規制できる。たとえ、固定ピース８９が係合突起３９・４５から浮き離れる状態であったとしても、スイッチボタン６６を押し込み操作する際に、固定ピース８９を適正な係合状態に復帰できる。側枠５２の上端に配置される化粧ピース６８を利用してスイッチボタン６６を配置するので、本体部２の前面や後面などにスイッチ構造を配置する場合に比べて、スイッチボタン６６が目立つのを防いで電気かみそりの外観をシンプルなものとし、デザイン性を向上することができる。 When the switch button 66 is disposed between the fixed piece 89 and the decorative piece 68, the switch button 66 can regulate the separation of the fixed piece 89 from the engagement protrusions 39 and 45. Even if the fixed piece 89 floats away from the engagement protrusions 39 and 45, the fixed piece 89 can be returned to the proper engagement state when the switch button 66 is pushed. Since the switch button 66 is arranged using the decorative piece 68 arranged at the upper end of the side frame 52, the switch button 66 is more conspicuous than the case where the switch structure is arranged on the front surface or the rear surface of the main body 2. The appearance of the electric razor can be simplified and the design can be improved.

化粧ピース６８を本体部２に差し込み係合した抜止ピース９７で分離不能に固定する係合構造によれば、例えば、弾性係合爪１００が係合突起３９・４５から脱落し、あるいは弾性係合爪１００が破損したとしても、化粧ピース６８が本体部２から分離するのを抜止ピース９７で阻止して、化粧ピース６８の組み付け状態を維持できる。 According to the engagement structure in which the decorative piece 68 is fixed so as not to be separated by the retaining piece 97 inserted and engaged with the main body 2, for example, the elastic engagement claw 100 falls off from the engagement protrusions 39 and 45, or the elastic engagement Even if the nail | claw 100 is damaged, it can prevent that the cosmetic piece 68 isolate | separates from the main-body part 2 with the retaining piece 97, and the assembly | attachment state of the cosmetic piece 68 can be maintained.

本体部２に配置されるきわ剃りユニット４で抜止ピース９７の外面を覆うと、抜止ピース９７が電気かみそりの外面に露出するのをきわ剃りユニット４で防止できる、さらに、抜止ピース９７が本体ケース２５から抜け外れるのをきわ剃りユニット４で阻止できる。 Covering the outer surface of the retaining piece 97 with the shaving unit 4 arranged in the main body 2 can prevent the retaining piece 97 from being exposed on the outer surface of the electric razor. The shave unit 4 can be prevented from coming off 25.

スイッチボタン６６を化粧ピース６８の側面に開口した操作窓６９ａを介して外面に露出させると、電気かみそりの外面のうちでも、目立たない個所に目立たない状態でスイッチボタン６６を配置できる。したがって、本体部２の前面や後面の外観をすっきりさせて、電気かみそり全体の印象をシンプルでデザイン性に優れたものとすることができる。 When the switch button 66 is exposed to the outer surface through the operation window 69a opened on the side surface of the decorative piece 68, the switch button 66 can be arranged in an inconspicuous position on the outer surface of the electric razor. Therefore, the appearance of the front and rear surfaces of the main body 2 can be made clear, and the overall impression of the electric shaver can be made simple and excellent in design.

スイッチボタン６６を防護枠３の外郭線の左右幅内に配置すると、外部から加わる衝撃を防護枠３で受け止めて、スイッチボタン６６を保護できる。あるいは、電気かみそりが他物と衝突するような場合に、スイッチボタン６６が押し込まれてオン状態に切り換わるのを防護枠３で防止できる。 When the switch button 66 is disposed within the lateral width of the outline of the protective frame 3, it is possible to protect the switch button 66 by receiving an impact applied from the outside by the protective frame 3. Alternatively, when the electric razor collides with another object, the protective frame 3 can prevent the switch button 66 from being pushed and switched to the on state.

防護枠３を透明プラスチック材で形成すると、透明な側枠５３および底枠５４を介して防護枠３の前後面を見通すことができるので、防護枠３と一体化された本体部２が宙に浮いているような印象を与えることができ、デザイン性を向上できる。また、防護枠３の全体が透明であるため、防護枠を不透明なプラスチック材で形成する場合に比べて、防護枠３より幅狭の本体部２が強調されることになり、全体として電気かみそりの印象をスリムなものとすることができる。 When the protective frame 3 is formed of a transparent plastic material, the front and rear surfaces of the protective frame 3 can be seen through the transparent side frame 53 and the bottom frame 54, so that the main body 2 integrated with the protective frame 3 is suspended in the air. A floating impression can be given and design can be improved. Further, since the entire protective frame 3 is transparent, the main body 2 narrower than the protective frame 3 is emphasized as compared with the case where the protective frame is formed of an opaque plastic material, and the electric shaver as a whole. The impression can be made slim.

防護枠３に発光表示部５８を設けると、防護枠３が透明であることを利用して表示部を構成できるので、発光表示部５８の構造を簡素化できる。さらに、発光表示部５８を構成する光源や、表示光を表示位置まで案内する導光体などの構成部品を、堅牢な防護枠３で保護することができる。 When the light emitting display part 58 is provided in the protective frame 3, the display part can be configured by utilizing the fact that the protective frame 3 is transparent, so that the structure of the light emitting display part 58 can be simplified. Furthermore, components such as the light source that constitutes the light emitting display unit 58 and the light guide that guides the display light to the display position can be protected by the robust protective frame 3.

本体部２の内部に光源６３を配置し、防護枠３の側枠５３に設けた凹部の内奥に反射面６１を形成して、光源６３から発光された表示光を反射面６１で前面側へ向かって反射する発光表示部５８によれば、使用者は反射面６１で反射された光を見ることになり、反射面６１に入射する光を見ることはできない。そのため、側枠５３の内部に位置する反射面６１が光源であるかのような印象を与え、さらに、反射面６１が透明な側枠５３の内部で宙に浮いたような幻想的な印象を与えることができる。また、光源６３から発光された表示光を、側枠５３の内部に設けた反射面６１で前面側へ向かって反射するので、折れ曲がった光路によって発光表示を行なうにもかかわらず、発光表示部５８の構造を簡素化して、コスト削減に寄与できる。 A light source 63 is disposed inside the main body 2, a reflective surface 61 is formed in the inner part of the recess provided in the side frame 53 of the protective frame 3, and display light emitted from the light source 63 is reflected on the front surface side by the reflective surface 61. According to the light emitting display unit 58 that reflects toward the user, the user sees the light reflected by the reflecting surface 61 and cannot see the light incident on the reflecting surface 61. Therefore, an impression is given as if the reflecting surface 61 located inside the side frame 53 is a light source, and a fantastic impression that the reflecting surface 61 floats in the air inside the transparent side frame 53 is provided. Can be given. Further, since the display light emitted from the light source 63 is reflected toward the front surface by the reflecting surface 61 provided inside the side frame 53, the light emitting display section 58 is provided regardless of the light emitting display by the bent optical path. This can simplify the structure and contribute to cost reduction.

本体ケース２５の内部に内ケース２６を配置し、その内部に、モーター１４、電池２８、および回路基板２９などの電装品ユニットを収容すると、防護枠３を含めて３層の構造体で脆弱な電装品ユニットを保護できるので、耐久性を向上して故障しにくい電気かみそりとすることができる。 When the inner case 26 is disposed inside the main body case 25 and an electrical component unit such as the motor 14, the battery 28, and the circuit board 29 is accommodated therein, the three-layer structure including the protective frame 3 is fragile. Since the electrical component unit can be protected, it is possible to improve the durability and make the electric razor less likely to break down.

内ケース２６とヘッド部２との間の隙間を塞ぐパッキン３４を設け、パッキン３４の外面を本体ケース２５の上部で覆うようにすると、パッキン３４が電気かみそりの外面に露出するのを避けながら本体ケース２５で保護できる。したがって、他物との接触によって脆弱なパッキン３４が傷つけられあるいは破損されるのを防いで、防塵機能および防水機能を長期にわたって安定した状態で発揮させることができる。パッキン３４を本体ケース２５で覆って隠蔽することにより、外観上の印象をシンプルなものとして、デザイン性を向上できる。 When a packing 34 that closes the gap between the inner case 26 and the head portion 2 is provided and the outer surface of the packing 34 is covered with the upper portion of the main body case 25, the main body is avoided while the packing 34 is exposed to the outer surface of the electric razor. The case 25 can protect it. Therefore, it is possible to prevent the fragile packing 34 from being damaged or broken due to contact with other objects, and to exhibit the dustproof function and the waterproof function in a stable state over a long period of time. By covering and concealing the packing 34 with the main body case 25, the appearance can be simplified and the design can be improved.

The upper end of the packing 34 is sandwiched between the joint surfaces of the head base 7 and the motor holder 13, and the lower end of the packing 34 is sandwiched between the upper ends of the inner case 26 and the inner frame 27.

図６および図７に示すように本体ケース２５は、前後に２分割された前ケース２５ａおよび後ケース２５ｂで構成する。前ケース２５ａは、前突状の湾曲壁からなる前壁３６と、前壁３６に連続する左右一対の側壁３７・３７と、前壁３６および側壁３７・３７の下端に連続する底壁３８とで樋体状に形成してある。両側壁３７・３７の上端寄りには、前ケース２５ａを防護枠３に固定するための係合突起３９が横臥Ｌ字状に突設してある。側壁３７の前縁寄りには、後述する側枠５３の前面内縁を受け止める段部４０が形成してある（図１１参照）。 As shown in FIGS. 6 and 7, the main body case 25 includes a front case 25 a and a rear case 25 b which are divided into two in the front and rear directions. The front case 25a includes a front wall 36 formed of a front-projecting curved wall, a pair of left and right side walls 37 and 37 that are continuous with the front wall 36, and a bottom wall 38 that is continuous with the front wall 36 and the lower ends of the side walls 37 and 37. It is formed in a box shape. Engagement protrusions 39 for fixing the front case 25a to the protective frame 3 are provided in a horizontal L-shape near the upper ends of the side walls 37. Near the front edge of the side wall 37, a step 40 is formed to receive the inner front edge of the side frame 53 described later (see FIG. 11).

後ケース２５ｂは、後突状の湾曲壁からなる後壁４１と、前壁４１に連続する左右一対の側壁４２・４２と、後壁４１および側壁４２・４２の下端に連続する底壁４３とで樋体状に形成してある。後壁４１の上部にはきわ剃りベース４４が一体に形成してあり、その外面にきわ剃りユニット４が組み付けられる。両側壁４２・４２の上端寄りには、後ケース２５ｂを防護枠３に固定するための係合突起４５が横臥Ｌ字状に突設してある。側壁４２の後縁寄りには、後述する側枠５３の後面内縁を受け止める段部４６が形成してある（図１１参照）。 The rear case 25b includes a rear wall 41 formed of a rear-projecting curved wall, a pair of left and right side walls 42 and 42 that are continuous with the front wall 41, and a bottom wall 43 that is continuous with the rear wall 41 and the lower ends of the side walls 42 and 42. It is formed in a box shape. A shaving base 44 is integrally formed on the upper portion of the rear wall 41, and the shaving unit 4 is assembled on the outer surface thereof. Engagement protrusions 45 for fixing the rear case 25b to the protective frame 3 project in a horizontal L shape near the upper ends of the side walls 42 and 42. Near the rear edge of the side wall 42, a step 46 is formed for receiving the rear inner edge of the side frame 53 described later (see FIG. 11).

内ケース２６は有底筒状に形成してあり、その底壁の下方から挿通される左右一対のビス４７（図８参照）を内フレーム２７の下端のねじボスにねじ込むことにより、内フレーム２７が分離不能に固定してある。内ケース２６の後面下部には、充電用のプラグ４８を備えたソケット４９がビスで締結固定してある（図６参照）。プラグ４８は、後ケース２５ｂの後面下部に開口したプラグ窓５０を介してケース外面に臨ませてある。 The inner case 26 is formed in a bottomed cylindrical shape, and a pair of left and right screws 47 (see FIG. 8) inserted from below the bottom wall are screwed into a screw boss at the lower end of the inner frame 27, thereby Is fixed inseparable. A socket 49 having a charging plug 48 is fastened and fixed to the lower rear surface of the inner case 26 with screws (see FIG. 6). The plug 48 faces the outer surface of the case through a plug window 50 opened at the lower rear surface of the rear case 25b.

防護枠３は、透明なアクリル樹脂あるいはポリカーボネイト樹脂を素材とする射出成形品からなり、左右一対の側枠（縦枠）５３・５３と、両側枠５３・５３の下端どうしを繋ぐ底枠５４とで逆門形に形成してある。両側枠５３・５３の対向面、および底枠５４の上面には、不透明な塗料を塗布して隠蔽層５５が形成してある（図１参照）。隠蔽層５５を設けることにより、防護枠３の内部に組み付けた本体部２の両側面および底面が視認されるのを防止できる。 The protective frame 3 is made of an injection-molded product made of a transparent acrylic resin or polycarbonate resin, and includes a pair of left and right side frames (vertical frames) 53 and 53, and a bottom frame 54 connecting the lower ends of both side frames 53 and 53. It is formed in a reverse portal shape. A concealing layer 55 is formed on the opposing surfaces of the side frames 53 and 53 and the upper surface of the bottom frame 54 by applying an opaque paint (see FIG. 1). By providing the concealing layer 55, it is possible to prevent the both side surfaces and the bottom surface of the main body 2 assembled inside the protective frame 3 from being visually recognized.

隠蔽層５５は、側枠５３・５３および底枠５４を介して視認されるので、側枠５３・５３および底枠５４の透明感と相俟って、防護枠３の外観の印象をシンプルなデザインでありながら高級感に富み、重厚なものとすることができる。とくに、側枠５３および底枠５４を、ぶ厚く太いプラスチックブロック状に形成して、防護枠３の外観上の印象を堅牢で重厚感に富むものとしている。具体的には、両側枠５３の左右幅を１０ｍｍ、底枠５４の上下高さを２１ｍｍ、両枠５３・５４の前後厚みを１６ｍｍとしている。ヘッド部１の左右幅と、防護枠３の左右幅はほぼ一致している。このように、底枠５４の上下高さを、側枠５３の左右幅および前後厚みに比べて大きく設定すると、重心位置を防護枠３の下半側に位置させることができるので、防護枠３を縦長姿勢で立てた状態の安定感を向上できる。さらに、防護枠３を立てた状態で本体部２を組み付けることができるので、組み付け性を向上できる。なお、この実施例における防護枠３の重量は４９ｇ、前ケース２５ａの重量は９ｇ、後ケース２５ｂの重量は８．６ｇ、内ケース２６の重量は１０ｇである。 Since the concealment layer 55 is visually recognized through the side frames 53 and 53 and the bottom frame 54, the impression of the appearance of the protective frame 3 is simplified in combination with the transparency of the side frames 53 and 53 and the bottom frame 54. Although it is a design, it is rich in luxury and can be made profound. In particular, the side frame 53 and the bottom frame 54 are formed in a thick and thick plastic block shape so that the appearance of the protective frame 3 is robust and rich. Specifically, the lateral width of both side frames 53 is 10 mm, the vertical height of the bottom frame 54 is 21 mm, and the longitudinal thickness of both frames 53 and 54 is 16 mm. The left-right width of the head portion 1 and the left-right width of the protective frame 3 are substantially the same. As described above, when the vertical height of the bottom frame 54 is set to be larger than the horizontal width and the front-rear thickness of the side frame 53, the center of gravity can be positioned on the lower half side of the protective frame 3, so that the protective frame 3 It is possible to improve the sense of stability when standing in a vertically long position. Furthermore, since the main-body part 2 can be assembled | attached in the state which stood the protective frame 3, assembly | attachment property can be improved. In this embodiment, the weight of the protective frame 3 is 49 g, the weight of the front case 25 a is 9 g, the weight of the rear case 25 b is 8.6 g, and the weight of the inner case 26 is 10 g.

各側枠５３の上端には、本体ケース２５の前後ケース２５ａ・２５ｂを固定するための係合部５７が形成してある。図９に示すように係合部５７は、側枠５３の上端から上向きに突出する縦壁５７ａと、縦壁５７ａの上端に連続して外側方へ突出する横壁５７ｂとで逆Ｌ字状に形成してある。これにより、側枠５３の上端に防護枠３の中央部側へ向かって凹む係止凹部５６を備えた係合部５７が形成される。左右の係合部５７のうち、右方の係合部５７に限って円形の穴５７ｃが左右貫通状に形成してある。 At the upper end of each side frame 53, an engaging portion 57 for fixing the front and rear cases 25a and 25b of the main body case 25 is formed. As shown in FIG. 9, the engaging portion 57 is formed in an inverted L shape by a vertical wall 57a protruding upward from the upper end of the side frame 53 and a horizontal wall 57b protruding outward from the upper end of the vertical wall 57a. It is formed. Thereby, the engaging part 57 provided with the latching recessed part 56 dented toward the center part side of the protective frame 3 in the upper end of the side frame 53 is formed. Of the left and right engaging portions 57, only the right engaging portion 57 is formed with a circular hole 57c penetrating left and right.

右側の側枠５３の上端寄りには発光表示部５８が設けてある。図８および図１１に示すように発光表示部５８は、モーター１４が通電状態にあるとき表示される第１表示部５９と、２次電池２８が充電状態にあるとき表示される第２表示部６０とで構成する。両表示部５９・６０は、それぞれ側枠５３の後面側に設けた断面が四角形状の凹部で形成してあり、凹部の内奥に斜めの反射面６１を備えている。 A light emitting display portion 58 is provided near the upper end of the right side frame 53. As shown in FIGS. 8 and 11, the light-emitting display unit 58 includes a first display unit 59 that is displayed when the motor 14 is in an energized state and a second display unit that is displayed when the secondary battery 28 is in a charged state. 60. Both display parts 59 and 60 are each formed with a quadrangular concave section provided on the rear surface side of the side frame 53, and are provided with an oblique reflecting surface 61 inside the concave section.

上記の第１・第２の表示部５９・６０に対応して、本体部２の側壁寄りの内部に光源６３を上下に配置し、さらに、光源６３と対向する内ケース２６の周壁に透明な導光板６４を固定している。各光源６３はチップ型のＬＥＤ（発光ダイオード）からなり、内ケース２６に収容した回路基板２９に実装してある。各光源６３は、側枠５３へ向かって表示光を照射する。詳しくは、各光源６３から発光された表示光は、導光板６４を介して第１・第２の表示部５９・６０へ到達し、それぞれの反射面６１で電気かみそりの前面側へ向かって反射される。したがって、使用者は各表示部５９・６０の発光状態を視認して、電気かみそりが運転状態にあること、あるいは充電状態にあることを知ることができる。因みに、電気かみそりと正対する状態の使用者は、側枠５３の内部に位置する反射面６１で反射された光を見ることになり、反射面６１に入射する光を見ることはできない。そのため、反射面６１が透明な側枠５３の内部で宙に浮いたような印象を与えることができる。上記のように光源６３および導光板６４は、本体部２の側壁寄りに設けられるが、その外面が剛性に富む防護枠３の側枠５３で覆われるので、落下衝撃を受けるような場合でも破損しにくい。 Corresponding to the first and second display portions 59 and 60 described above, the light source 63 is vertically arranged inside the main body 2 near the side wall, and further transparent on the peripheral wall of the inner case 26 facing the light source 63. The light guide plate 64 is fixed. Each light source 63 is formed of a chip-type LED (light emitting diode) and mounted on a circuit board 29 accommodated in the inner case 26. Each light source 63 irradiates display light toward the side frame 53. Specifically, the display light emitted from each light source 63 reaches the first and second display portions 59 and 60 via the light guide plate 64, and is reflected toward the front side of the electric razor by the respective reflection surfaces 61. Is done. Therefore, the user can visually recognize the light emission state of each of the display units 59 and 60 and know that the electric razor is in the operating state or in the charged state. Incidentally, the user in a state of facing the electric razor sees the light reflected by the reflecting surface 61 located inside the side frame 53, and cannot see the light incident on the reflecting surface 61. Therefore, it is possible to give an impression that the reflecting surface 61 floats in the air inside the transparent side frame 53. As described above, the light source 63 and the light guide plate 64 are provided near the side wall of the main body 2. However, since the outer surface is covered with the side frame 53 of the protective frame 3 having a high rigidity, the light source 63 and the light guide plate 64 are damaged even when receiving a drop impact. Hard to do.

発光表示部５８の上部側に隣接して、モーター１４への通電状態を切り換えるスイッチボタン６６を配置し、スイッチボタン６６と対向する本体部２の内部にスイッチ６７を配置している。スイッチ６７はチップ化してあり、内ケース２６に収容した回路基板２９に実装してある。図９および図１０においてスイッチボタン６６は、長方形状の操作部６６ａと、操作部６６ａの内面中央に突設される操作軸６６ｂとを一体に備えており、その周囲は本体ケース２５に係合装着した化粧ピース６８で覆われている。この化粧ピース６８の側壁には、操作部６６ａを外面に露出させる操作窓６８ａが開口してある。 A switch button 66 for switching the energization state of the motor 14 is disposed adjacent to the upper side of the light emitting display section 58, and a switch 67 is disposed inside the main body section 2 facing the switch button 66.
