。[Detailed description of the invention] The present invention has a protrusion for engaging the inner blade body on the upper surface of the fitting part of the rotating eccentric cam on the lower surface of the flat part, and the lower end of the flat part is inserted into the main body case from both sides. The present invention relates to a vibrating electric shaver in which the inner cutter body is reciprocated by a vibrator having a mouth-shaped overall shape and having elastic legs fixed in place, and in particular, the vibrator is moved upward in response to external pressure. The shape of the blade is designed to generate repulsive force, eliminating the need for a spring to push up the inner blade.
This realizes a simplified structure and cost reduction.

以下、本考案の一実施例を図面に基づいて説明すると、
１は電気かみそりの本体ケース、２はモーター３をネジ
４，４で支持固定する基板で、両端に起立片５，５を有
する。Hereinafter, one embodiment of the present invention will be described based on the drawings.
1 is a main body case of an electric shaver; 2 is a board for supporting and fixing a motor 3 with screws 4, 4, and has upstanding pieces 5, 5 at both ends.

６はモーター軸に固定した偏心カムである。6 is an eccentric cam fixed to the motor shaft.

７は合成樹脂により成る振動子にして、平担部８の下面
に前記偏心カム６との嵌合部９、上面に内刃体１０との
係合突起１１が設けられ、平担部８の両側からは、開口
部１２．１２を介して両側の脚１３．１３が若干中央で
浅くく字状に屈曲している弾性脚１４．１４が一体に形
成され、更に該弾性脚１４．１４の下端にはヒンジ部１
５，１５を介して肉厚の取付足部１６．１６が水平に設

ている。Reference numeral 7 designates a vibrator made of synthetic resin, and the lower surface of the flat portion 8 is provided with a fitting portion 9 for engaging the eccentric cam 6, and the upper surface is provided with an engaging protrusion 11 for engaging the inner blade 10. From both sides, the legs 13.13 on both sides are integrally formed with an elastic leg 14.14 bent in a shallow dogleg shape slightly in the center through the opening 12.12, and the elastic leg 14.14 is bent slightly in the center. Hinge part 1 at the bottom end
A thick-walled mounting foot 16.16 is provided horizontally via 5, 15, in which a rectangular mounting hole 17.17 is drilled.

従って、前記取付足部１６．１６の取付付孔１７，１７
を前記基板２の起立片５，５に嵌め込み、この部分を共

く装着固定される。Therefore, the mounting holes 17, 17 of the mounting foot 16.16
is fitted into the upright pieces 5, 5 of the base plate 2, and these parts together form a U-shaped rib 18.1 formed inside the main body case 1.
8 from the horizontal direction, it is installed and fixed as shown in FIGS. 1 and 2.

１９は外刃枠にして、外刃２０がアーチ状に張設されて
おり前記内刃体１０を押下げる程度の寸法で本体ケース
１の上部に着脱自在に嵌着される。Reference numeral 19 designates an outer cutter frame, on which an outer cutter 20 is extended in an arch shape, and is detachably fitted into the upper part of the main body case 1 with a size that is large enough to push down the inner cutter body 10.

２１は本体ケース１の側壁１′よりコイルス。プリング
２２で常時突出している係止鈎で、前記外刃枠１９の一
方と嵌合し、又２３は該外刃枠１９の他方と係合する固
定の突起である。21 is a coil from the side wall 1' of the main body case 1. A locking hook that is always protruding from the pull 22 is engaged with one side of the outer cutter frame 19, and 23 is a fixed protrusion that is engaged with the other side of the outer cutter frame 19.

以上の構成で次に本考案の作用を述べると、第２図のよ
うに外刃枠１９を本体ケース１にセットしない時は、振
動子７の弾性脚１４．１４には上部から外圧が掛かつて
おらずこの弾性脚１４，１４の屈曲に基づく上方への弾
力は作用していない。With the above configuration, the operation of the present invention will be described next. When the outer cutter frame 19 is not set in the main body case 1 as shown in FIG. For the first time ever, the upward elasticity based on the bending of the elastic legs 14, 14 is not acting.

然し、第１図の様に外刃枠１９をセットすると、外刃２
０が内刃体１０の刃片１０’、１０’・・・に当たり、
内刃体１０全体を若干押下げることになる。However, when the outer cutter frame 19 is set as shown in Fig. 1, the outer cutter 2
0 corresponds to the blade pieces 10', 10'... of the inner blade body 10,
The entire inner blade body 10 will be pushed down slightly.

それにより、振動子７自体も押し下げられる。As a result, the vibrator 7 itself is also pushed down.

その結果、弾性脚１４．１４はより深＜、＜の字状に内
方へ屈曲せしめられ、そして、その屈曲による反撥弾力
が上方への附勢力となって、内刃体１０全体を押上げる
よう作用し、内刃体１０の刃片１０’、１０’・・・と
外刃２０との密着をより一層強いものとする。As a result, the elastic legs 14.14 are bent inward in a deeper <, < shape, and the repulsive force caused by the bending becomes an upward force, pushing up the entire inner blade body 10. This acts to further strengthen the close contact between the blade pieces 10', 10', . . . of the inner blade body 10 and the outer blade 20.

この弾性脚１４．１４の屈曲に基づく上方への復元弾力
はひげそり時に、外刃２０に掛かる皮膚面からの押圧力
に追従して変わり、従来の振動子７と内刃体１０との間
に介挿された内刃押上バネと同等の働きをすることにな
る。The upward restoring elasticity based on the bending of the elastic legs 14.14 changes in accordance with the pressing force from the skin surface applied to the outer cutter 20 during shaving, and the difference between the conventional vibrator 7 and the inner cutter 10 is It functions in the same way as the inserted inner blade push-up spring.

よって、内刃押上げバネが不要なので、従来の様に該バ
ネを一つ一つ内刃体に装着すると言う面倒な作業が省け
、組み立てが容易になると共に、バネ力の不揃いにより
均等した品質のものが得られ難いと言う欠点がなくなる
。Therefore, since there is no need for a spring to push up the inner blade, the troublesome work of attaching the springs to the inner blade body one by one as in the conventional method is eliminated, making assembly easier, and uniform quality due to uneven spring force. The drawback of being difficult to obtain things is eliminated.

脚がこのく字状々態を越える程に深く屈曲され、その時
上方への復元弾性力が働いて振動子全体を上方へ附勢せ
しめるよう作用する結果、内刃体の各月と外刃との密着
は確実に保たれ、従来と変わらぬ切れ味が得られる。As described above, the present invention has a fitting part for the rotating eccentric cam on the lower surface of the flat part, a protrusion for engaging with the inner blade body on the upper surface, and the lower ends of the elastic legs provided on both sides are fixed appropriately within the main body case. In those that reciprocate the inner blade using a vibrator with a mouth-shaped overall shape,
Conventionally, an inner blade pushing spring was interposed between the inner blade and the vibrator, and this spring pushed up the inner blade and applied blade pressure with the outer blade, but in the present invention, this spring This structure simplifies the structure and provides uniform blade pressure by omitting the above-mentioned elastic legs. The elastic legs are bent deeply enough to exceed this dogleg state due to the pressing force applied from the skin surface through the outer cutter during shaving, and at that time, the upward restoring elastic force acts to move the entire vibrator upward. As a result of the energizing action, the close contact between each month of the inner blade body and the outer blade is reliably maintained, and the same sharpness as before can be obtained.

又、外部からの押圧力に応じて前記弾性脚はその屈曲度
合が変化し、それに応じた上方への弾性力を付与してい
るので、常時安定した刃圧が得られ、従来の様に装着さ
れる内刃押上バネによって夫々バネ力が異なり、刃圧が
不揃いとなる懸念が解消される。In addition, the degree of bending of the elastic leg changes according to the external pressing force, and a corresponding upward elastic force is applied, so that stable blade pressure can be obtained at all times, and it can be worn as usual. The spring force differs depending on the inner blade push-up spring, which eliminates the concern that the blade pressure will be uneven.

以上の様に非常に簡単な装置で、従来の内刃押上げバネ
を不要とし、且刃圧力は十分に発揮できる振動式電気か
みそりの振動子が提供でき、その実用的効果は犬である
。As described above, it is possible to provide a vibrator for a vibrating electric shaver that does not require the conventional inner blade push-up spring and can exert sufficient blade pressure using a very simple device, and its practical effects are outstanding.
