【考案の詳細な説明】 この考案は、内刃を直線往復運動させる型式の電気かみ
そりの内刃取付装置に関するものである。[Detailed Description of the Invention] This invention relates to an inner cutter attachment device for an electric shaver that causes the inner cutter to move in a linear reciprocating manner.

この種の電気かみそりにおいては、駆動部の対して内刃
を外せるように腰かつ装着時には切味を保つために内刃
を外刃に密着させる必要がある。In this type of electric shaver, it is necessary to hold the inner cutter in close contact with the outer cutter so that the inner cutter can be removed from the drive unit, and to maintain sharpness when worn.

従来は、駆動部に連結されて直線往復運動する作動体に
嵌合部を形成し、この嵌合部に嵌合されるピンを内刃に
抜は止めしつつ設けたり内刃と一体的に形成し、これら
の嵌合部とピンとを嵌合している。Conventionally, a fitting part is formed on the actuating body that is connected to the drive part and moves linearly reciprocatingly, and a pin that is fitted into this fitting part is provided on the inner cutter while preventing it from being removed, or it is integrated with the inner cutter. These fitting portions and pins are fitted into each other.

しかし、作動体の嵌合部がピンにより摩滅したり潰れて
外れ易くなり、また、ピンと嵌合部とに不自然な応力が
生じて内刃が外刃になじまず切味が低下する欠点を有し
ている。However, the fitting part of the actuating body is easily worn out or crushed by the pin and comes off easily, and unnatural stress is generated between the pin and the fitting part, causing the inner cutter to not fit in with the outer cutter and resulting in poor cutting quality. have.

この考案はこのような点に鑑みなされたもので、切味を
高めしかも内刃台と作動体との連結部の耐久性を高めう
る電気かみそりの内刃取付装置をうろことを目的とする
ものである。This idea was devised in view of these points, and the purpose is to create an inner blade attachment device for an electric shaver that can improve the cutting quality and the durability of the connection between the inner cutter stand and the operating body. It is.

し、しかも、内刃台と作動体との耐久性を高めうるよう
に構成したものである。This invention consists of a plurality of flexible locking pieces facing each other on one side of the inner cutter base that holds the inner cutter and an actuating body connected to the drive unit, and a locking edge that slopes in a reverse taper direction on the other side. forming and elastically deflecting the flexible locking piece to engage the locking edge, thereby
It prevents the inner cutter stand from falling off from the operating body, allows the inner cutter to conform to the outer cutter due to the bending action of the flexible locking piece, maintains good cutting quality, and also improves the durability of the inner cutter stand and the operating body. It is designed to enhance the character.

この考案の一実施例を図面に基いて説明する。An embodiment of this invention will be explained based on the drawings.

１は本体ケースで、この本体ケース１の中には図示しな
いがモータ等の駆動部が収納され、一端には駆動部に連
結されて軸方向と直交する方向に直線往復運動する軸２
が突出されている。Reference numeral 1 designates a main body case. Although not shown in the main body case 1, a drive unit such as a motor is housed in the main body case 1. A shaft 2 is connected to the drive unit at one end and moves in a linear reciprocating direction in a direction perpendicular to the axial direction.
is prominent.

この軸２には作動体である内刃取付台３が連結されてい
る。An inner cutter mount 3, which is an operating body, is connected to this shaft 2.

すなわち、軸２には内刃押上ばね４の上端に当接するば
ね受５がピン６により抜は止めされつつ嵌合され、この
ばね受５はその両側から突出する支軸７を前記内刃取付
台３に形成した軸孔８に嵌合することにより内刃取付台
３に対し相対的にシーン運動自在に保持されている。That is, a spring receiver 5 that contacts the upper end of the inner blade push-up spring 4 is fitted onto the shaft 2 while being prevented from being removed by a pin 6, and this spring receiver 5 has a support shaft 7 protruding from both sides of the spring receiver 5 that is attached to the inner blade. By fitting into a shaft hole 8 formed in the base 3, it is held so as to be movable relative to the inner cutter mounting base 3.

ついで、内刃９を保持する内刃台１０が設けられている
。Next, an inner cutter stand 10 for holding the inner cutter 9 is provided.

この内刃台１０は弾性を有する樹脂により形成されたも
ので、相対向する可撓係止片１１とこれらの可撓係止片
１１の外側に位置するストッパ１２とを有している。This inner cutter base 10 is made of elastic resin and has flexible locking pieces 11 facing each other and a stopper 12 located outside of these flexible locking pieces 11.

そして、これらの可撓係止片１１に係合する係止縁１３
が前記内刃取付台３の両側に形成されている。A locking edge 13 that engages with these flexible locking pieces 11
are formed on both sides of the inner cutter mounting base 3.

これらの係止縁１３は上方に向うにつれ外側に拡開する
方向に傾斜しつつ形成されている。These locking edges 13 are formed so as to be inclined in a direction that widens outward as they go upward.

また、前記本体ケース１には外刃１４を湾曲しつつ保持
する外刃ケース１５が係止爪１６，１７により着脱自在
に取付けられている。Further, an outer cutter case 15 that holds the outer cutter 14 in a curved manner is detachably attached to the main body case 1 by locking claws 16 and 17.

１８は外刃１４を保護するカバーである。18 is a cover that protects the outer cutter 14.

このような構成において、内刃取付台３に内刃台１０を
内刃９とともに取付けるには、第５図ａに示すように内
刃台１０を内刃取付台３に対向させ、第５図Ｃに示すよ
うに係止縁１３に可撓係止片１１を係合する。In such a configuration, in order to attach the inner cutter stand 10 to the inner cutter mount 3 together with the inner cutter 9, the inner cutter stand 10 should be opposed to the inner cutter mount 3 as shown in FIG. As shown in C, the flexible locking piece 11 is engaged with the locking edge 13.

このときに、第５ｂに示すように可撓係止片１１を片側
ずつ係合すると連結作業も容易である。At this time, if the flexible locking pieces 11 are engaged on one side at a time as shown in No. 5b, the connection work can be facilitated.

また、このときに可撓係止片１１は弾性的に外側に撓む
が過剰な動きはストッパ１２により制限するので弾性を
失ったり折損することはない。Further, at this time, the flexible locking piece 11 bends elastically outward, but excessive movement is restricted by the stopper 12, so that it does not lose its elasticity or break.

また、係止縁１３は上方に向うにつれ拡開し、可撓係止
片１１も自らの弾性により内方向へ付勢されているので
係合力は強く、内刃取付台３からの内刃台１０の脱落は
防止される。Further, the locking edge 13 widens upward, and the flexible locking piece 11 is also urged inward by its own elasticity, so the engagement force is strong, and the inner cutter base from the inner cutter mounting base 3 10 is prevented from falling off.

ひげそりに際しては内刃取付台３と内刃台１０及び内刃
９が直線往復運動するが、内刃９は内刃押圧ばね４によ
り上方へ付勢され、ばね受５も内刃取付台３もシーソ運
動自在であり、しかも、内刃台１０の可撓係止片１１は
弾性的に屈撓しうる。During shaving, the inner blade mount 3, the inner blade holder 10, and the inner blade 9 move linearly back and forth, but the inner blade 9 is urged upward by the inner blade pressing spring 4, and the spring receiver 5 and the inner blade mount 3 are It is movable in a see-saw manner, and the flexible locking piece 11 of the inner cutter stand 10 can be elastically bent.

したがって、内刃９は往復運動中宮に外刃１４になじみ
切味は良好である。Therefore, the inner cutter 9 conforms to the outer cutter 14 during reciprocating motion and has a good cutting quality.

また、係止縁１３や可撓係止片１１の摩耗や折損を防止
することが可能で耐久性は高い。Further, it is possible to prevent the locking edge 13 and the flexible locking piece 11 from being worn out or broken, and the durability is high.

なお、可撓係止片を内刃取付台に設け、係止縁を内刃台
に形成してもよいものである。Note that the flexible locking piece may be provided on the inner cutter mounting base, and the locking edge may be formed on the inner cutter base.

この考案は上述のように構成したので、可撓係止片の弾

しかも、内刃台と作動体との連結部の耐久性を高めるこ
とができる等の効果を有するものである。Since this device is configured as described above, the inner cutter can be brought into close contact with the outer cutter by the elastic bending action of the flexible locking piece, thereby improving the cutting quality, and the flexible locking piece can be elastically bent. By forming the locking edge that engages with the blade with a reverse taper, it is possible to strengthen the engagement force and prevent the inner cutter stand from falling off from the operating body.
Moreover, it has the effect of increasing the durability of the connecting portion between the inner cutter stand and the operating body.
