この発明は、電気かみそり刃に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an electric razor blade.
従来の電気かみそりで内刃と外刃が摺接しない
部分では、第１０図のようにひげ７０が刃穴７１
に侵入することによりひげそり時にひげ７０が方
向Ａに移動させられたとき刃穴７１の刃先７２で
ひげ７０を引張り、刺激を与えるという欠点があ
つた。また第１１図のように長いひげ（１〜３
mm）７３および女性のわき毛などは、毛先が刃穴
７４に入り、内刃などで毛先が倒されて隣りの刃
穴７５から毛先が外刃の表面側に飛び出してから
み状態となり、電気かみそりが移動することによ
つて刃穴７４，７５の刃先７６，７７で毛７３を
引張るという欠点があつた。
In conventional electric razors, where the inner and outer blades do not make sliding contact, the whiskers 70 are located in the blade holes 71 as shown in Figure 10.
When the beard 70 is moved in the direction A during shaving, the cutting edge 72 of the blade hole 71 pulls the beard 70, causing irritation. Also, as shown in Figure 11, long beards (1 to 3
mm) 73 and women's armpit hair, the tips of the hair enter the blade hole 74, are knocked down by the inner blade, etc., and the tips of the hair protrude from the adjacent blade hole 75 to the surface of the outer blade, resulting in a tangled state. There was a drawback that the hair 73 was pulled by the cutting edges 76 and 77 of the cutting holes 74 and 75 as the electric shaver moved.
これらの欠点を解消するものとして、従来、第
１２図および第１３図のように外刃の内刃摺動側
に、刃穴７８に対応する溝部７９をもつたコーム
８０が外刃８１の内側に付設されたものがあつ
た。 To solve these drawbacks, conventionally, as shown in FIGS. 12 and 13, a comb 80 having a groove 79 corresponding to the blade hole 78 on the sliding side of the inner cutter of the outer cutter is provided on the inner side of the outer cutter 81. There was something attached to it.
しかしながら、第１２図の場合ひげ８２の移動
方向Ａに対して刃穴７８の反対側刃先８３で毛を
引く機会は削減できたが、移動方向Ａ側の刃先８
４で毛８２を引く欠点があつた。これは特に刃穴
７８の毛導入幅Ｂが小さい程刃先８４に対する角
度が直角になり、引掛りの発生ひん度が大とな
る。 However, in the case of FIG. 12, the chance of pulling hair with the cutting edge 83 on the opposite side of the cutting hole 78 with respect to the moving direction A of the beard 82 could be reduced, but the cutting edge 83 on the moving direction A side could be reduced.
4 had the drawback of pulling 82 hairs. Particularly, the smaller the bristle introduction width B of the blade hole 78, the more perpendicular the angle to the blade edge 84, and the more likely the hair will get caught.
また第１３図の場合、溝部７９の幅と刃穴７８
の幅とを一致したものであるが、外刃８１は

りにより毛を引く欠点がある。 In addition, in the case of FIG. 13, the width of the groove 79 and the blade hole 78
However, the outer blade 81 is
While the main material is SUS or electroforming, the comb 80 is made of a material with good workability such as resin or aluminum.
Due to wear and chipping in the vicinity of the
Furthermore, the cutting edges 83 and 84 of the outer cutter 81 come out into the groove 79 due to rounding (sink marks, due to the mold structure) during molding, and thus pull the bristles 82 as well. Also, metals with good workability such as aluminum have the same drawbacks as molded resins, but they also have the disadvantage that burrs occur near the cutting edges 83 and 84 during processing of the groove 79, and the burrs draw hair.
また、外刃８１とコーム８０の組合せ工程にお

た。 Furthermore, in order to more reliably prevent the hair from getting caught in the part of the inner blade that does not make sliding contact, it has been proposed that the cutting edge part 86 of the cutting hole 85 is made into an arc as shown in FIG. 57-14375). However, with the electroforming method, it is extremely difficult to manufacture a matrix in which only the non-sliding parts of the inner and outer blades are machined into circular arcs, as shown in Figure 14, and the outer blade cannot be manufactured using the SUS material press method. The same applies to press mold production. Furthermore, it is possible to form methods in subsequent processes, such as masking the sliding contact areas of the inner and outer cutters and applying plastic processing or honing to the rest, but it is possible to stabilize the machining accuracy, It has disadvantages such as the strength of the outer cutter (part) and deformation of the outer cutter frame, as well as the disadvantage of high cost.
この発明の目的は、内刃が内接しない外刃の部
分における毛の引掛りをより確実に防止すること

The electric shaver blade of the present invention includes an outer cutter having a cutter hole, an inner cutter inscribed in a part of the outer cutter, and a portion of the outer cutter that is provided in close contact with the edge of the cutter hole that is not inscribed with the inner cutter. The comb has a groove corresponding to the blade hole, and a groove edge of the groove projects inward from the cutting edge of the blade hole.

きる。 According to the structure of this invention, the groove of the comb corresponds to the hole in the outer cutter where the inner cutter is not located, and the groove edge protrudes inwardly than the cutting edge, so that the hair introduced into the cutting hole is pulled by the cutting edge. This prevents hair from getting caught and allows you to shave comfortably. Furthermore, the structure is simple and can be realized at low cost.

たがつてモータ（図示せず）に連動する内刃フレ
ーム５の回転により、内刃８，９が外刃３の内面
を摺動し、刃穴１３に侵入したひげを切断する。 A first embodiment of the present invention will be described based on FIGS. 1 to 6. That is, in this rotary electric shaver blade, an outer cutter frame 1 is formed in a cylindrical shape, has a threaded portion 2 at one end, an outer cutter 3 is attached to the other end, and is held down by a cover 4. On the other hand, the inner cutter frame 5 is arranged inside the outer cutter frame 1, and the inner cutters 8 and 9 passed through the slits 6 and 7 of the inner cutter frame 5 are fixed to the lower surface of the inner cutter frame 5 by the heat seal part 10. The tip of the push-up spring 11 is supported by the opening 12 and inscribed in the inner surface of the outer cutter 3. Therefore, as the inner cutter frame 5 rotates in conjunction with a motor (not shown), the inner cutters 8 and 9 slide on the inner surface of the outer cutter 3 and cut the hair that has entered the cutter hole 13.

ひげの導入をよくするため摺接しない外刃に刃穴
を構成する必要があるためである。 By the way, as is clear from the figure, the outer cutter 3 has portions I 1 to I 4 that are not in contact with the inner cutter. This is because the outer cutter 3 has annular recesses 14 and 15 for introducing bristles and an outer peripheral wall 16, and due to the eccentricity between the outer and inner cutter sides and the eccentricity of the joint that connects the motor shaft and the inner cutter frame, the inner and outer cutters This is because there is a risk of interference between the two blades, and because it is necessary to form a hole in the outer blade that does not make sliding contact in order to improve the introduction of the whiskers.

の刃先を被覆している（第４図）。 Now, among the parts of the outer cutter 3 where the inner cutter does not come into sliding contact, a comb 17 is provided on the outer periphery of the outer cutter 3,
A groove 19 is formed in the comb 17, as shown in FIGS. 3 to 5, in correspondence with the outer circumferential cutting hole 18 of the outer cutter 3. That is, the width of the groove 19 is smaller than the width of the cutting hole 18, and the edge 20 of the groove 19 has a curved surface 20' and projects from the cutting edge 21 by an amount G (FIG. 3). In addition, the groove 19
The bottom surface 22 of is raised by K (Fig. 4). Further, the width B 2 of the outer peripheral hole 18 on the outer peripheral wall 16 side is widened, the width B 1 of the center side of the blade hole 18 is narrowed, and the end 17a of the comb 17 is connected to the connecting portion 2 of the different widths of the blade hole 18.
3 (Fig. 5), and the recess 24 as shown in Fig. 6.
prevent the formation of Further, a thin coating portion 25 of about 0.2 mm extends from the tip of the comb 17 to cover the cutting edge of the comb 17 at the blade hole 18 in the gap I between the inner cutter 9 (FIG. 4).

影響がない。 With this configuration, the edge 20 of the groove 19 of the comb 17 that is in close contact with the cutting edge 21 of the blade hole 18 protrudes inward, so that the bristles 26 do not catch the cutting edge 21. Moreover, it becomes more effective if the edge 20 of the groove 19 is made into a curved surface. Furthermore, if it is made of a molded resin material, it will be more slippery and the pulling force of the bristles 26 will be even smaller. Since the comb 17 is inscribed in the outer blade 3 and the groove 19 is formed in correspondence with the blade hole 18, entanglement of the hair 26, which is conventional, can be prevented. Fourth
As shown in the figure, a step K is formed on the bottom surface 22 of the groove 19 of the comb 17 from the end 18a of the blade hole 18 in the outer peripheral wall 16 of the outer cutter 3, which is the part where the outer cutter 3 protrudes toward the inner cutter 9 side. 17 protrudes toward the outer blade side, it is possible to prevent the bristles 26 from getting caught at the cutting edge of the end portion 18a of the cutter hole 18, and promote the effect of introducing the bristles, which is the function of the outer peripheral cutter hole 18. This point is the outer peripheral wall 1 of the outer cutter 3.
Not only the annular recesses 14 and 15 but also the annular recesses 14 and 15 can be similarly configured. Furthermore, it is necessary to form a gap I between the inner cutter 9 and the comb 17 in consideration of the eccentricity of the inner cutter side and the outer cutter side as described above. By extending the thin (approximately 0.2 mm) covering portion 25 to the blade wall blade hole 18, it is possible to prevent hairs from getting caught in the blade hole 18 in the gap I. Note that, depending on the dimensions, the tip of the covering portion 25 may intrude into the inner cutter side (indicated by 25'), but since it is made of synthetic resin, it is scraped off by the inner cutter 9, so no load noise or abnormality occurs. In addition, the inner blade sliding contact area on the center side of the blade hole 18 reduces the blade hole width B 1 due to stimulation.
The width B of the area on the outer peripheral wall 16 side needs to be large in order to introduce hair. In this case, as shown in FIG. 6, a recess 24 is formed that brings the end 17a of the comb 17 into the hair introduction area, and the whiskers 26 fit into the recess 24 and the hair 26 is pulled by the cutting edge. Since the end 17a of the comb 17 is provided so as to reach the width B1 side, there is no recess 24 and the bristles 26 are not caught. Furthermore, according to this embodiment, there is no deformation or deterioration in strength of the outer cutter 3, and the cost can be reduced. Also, interference between the inner and outer cutters can be prevented by supporting the comb 17, and furthermore, when the comb 17 is provided on the outer cutter 3, positional deviation may occur. Even if this occurs, the groove width is small, so there is no effect even if there is a slight deviation.
なお、第３図ないし第５図の構成は往復式電気
かみそりを適用することもできる。 Note that the configurations shown in FIGS. 3 to 5 can also be applied to a reciprocating electric shaver.

The width on the bottom side of 9' is increased by dimension H. In this case, the degree of freedom of the bristles 26 is increased from θ 1 to θ 2 compared to the first embodiment (imaginary line in the figure) in which the width is not increased.
(θ 1 <θ 2 ), and the pulling force of the hair can be reduced.
Also, since the volume of hair debris has increased, the amount of hair debris flying out is reduced.

ができる。 A third embodiment of the invention is shown in FIGS. 8 and 9. That is, a hair introduction groove 31a is formed in the center of the outer cutter 31 of the reciprocating electric shaver blade, a blade hole 33 is formed across the side wall 32 and the upper surface, and the groove 31a is formed in the center of the inner cutter 34. Escape recess 3
A comb 36 is provided in the recess 35 on the inner blade 34 side of the groove 31a, and the bottom 38 of the slit 37 corresponding to the blade hole 33 protrudes beyond the lower end 33a of the blade hole 33, and the blade edge 33 'a covered;
In addition, a thin coating portion 25' is extended from the comb 36 into the gap I' between the comb 36 and the inner cutter 34 to fill the gap.
The cutting edge of the cutting hole 33 at I' is covered. Note that 39 is a push-up spring. Therefore, the effect is that, like the first embodiment, it is possible to reliably prevent hair from getting caught at the cutting edge where no inner cutter is present.
