。(Prior Art) Conventionally, an assembled blade body attached to a holder has been provided with means for swinging around an axis extending in the longitudinal direction and returning the swung assembled blade body to its original position. Safety razors existed. The conventional mounting means for the assembled blade body consists of a journal shaft with a circular cross section provided at the tips of two arms extending from both sides of the upper part of the holder, and a journal bearing bored into the back surface of the assembled blade body. Met.
そしてこの従来のジャーナル軸の断面は、完全な円（真
円）であった。The cross section of this conventional journal shaft was a perfect circle.
（発明が解決しようとする問題点）
組立刃体の揺動を円滑にし、肌の凹凸に刃先を対応させ
る為には、ジャーナル軸の中心すなわち揺動軸線が刃体
の刃面に近いほど良い。逆に、揺動軸線が刃面から遠い
と刃先の振幅が大きくなり肌の凹凸しこ対応しにくくな
る。(Problem to be solved by the invention) In order to smoothly swing the assembled blade body and make the cutting edge correspond to the unevenness of the skin, it is better that the center of the journal shaft, that is, the swing axis, be closer to the blade surface of the blade body. . On the other hand, if the swing axis is far from the blade surface, the amplitude of the blade edge will be large and it will be difficult to deal with the unevenness of the skin.
従来の断面円形のジャーナル軸において揺動軸線を刃面
に近づけようとすると、軸の径か細くなり軸の強度が落
ちる。逆に軸の強度を維持しようとすると揺動軸線が刃
面から遠ざかる。In a conventional journal shaft with a circular cross section, if you try to bring the swing axis closer to the blade surface, the diameter of the shaft becomes smaller and the strength of the shaft decreases. Conversely, if you try to maintain the strength of the shaft, the axis of oscillation moves away from the blade surface.

提供することを目的とする。The present invention eliminates these drawbacks of conventional products, and provides a safety razor in which the assembled blade body can swing smoothly, and therefore the assembled blade body can swing in response to the unevenness of the facial surface during use. The purpose is to provide

付近から他方の縁部方向に延びている。The assembled blade body 1 includes two blade bodies 4 between a top plate 2 and a blade base 3.
4 are sandwiched and fixed, and a spacer 5 is interposed between the two blade bodies 4°4. A pair of ribs 6.6 are integrally provided on the back surface of the blade assembly 1, and journal bearings 7, 7 are bored in each rib 6.6. The width of the bearings 7, 7 is approximately the same as the diameter of the journal shaft 22.22, which will be described later, but the depth thereof is shorter than the diameter of the shaft 22.22. A cantilevered elastic member 8 is provided at the center of the back surface of the assembled blade 1 to elastically return the swung assembled blade 1 to its original position. The elastic member 8 is located at the longitudinal edge 9 of the assembled blade body 1.
It extends from the vicinity towards the other edge.

るので実際の使用に差支えない。(Function) The present invention has the above configuration, and the blade assembly 1 has a holder 20.
It is attached to the journal and can swing around the journal axis. Further, since the oscillated assembled blade body 1 returns to its original state due to the elastic force of the elastic member 8, the oscillation is repeated in response to the unevenness of the surface of the face during shaving. The depth of the bearings 7, 7 is shorter than the diameter of the shaft 22.22, but since the upper part of the shaft 22.22 is also missing and the range of swing of the assembled blade is limited, there is no problem in actual use. .

欠けていても、それらの下部同士の当接だけで組立刃体
１を回動させることができるので、不都合はない。(Effects) A feature of the present invention is that the upper portions of the journal shafts 22, 22 and their bearings 7, 7 are missing. This allows the swing axis of the journal shafts 22, 22 to be brought closer to the blade surface of the blade body 4, and smooth swing of the assembled blade body 1 can be obtained. Even if the upper parts of the journal shafts 22, 22 and the bearings 7, 7 are missing, there is no problem because the assembled blade body 1 can be rotated simply by the contact between their lower parts.
この発明はまた、ジャーナル軸２２．２２の太さを従来

増すことができる。This invention also makes it possible to make the journal shafts 22, 22 thicker than the conventional ones so that the pivot axis can be brought closer to the blade surface. If an attempt was made to move the swing axis closer to the blade surface while maintaining the conventional journal shaft shape (a perfect circular cross section), the diameter of the journal shaft would have to be made thinner, which would reduce the strength of the shaft. In this invention, the diameter of the shaft 22.22 can be increased to bring the swing axis closer to the blade surface, so the strength of the shaft 22.22 itself can be increased.
さらに、軸２２．２２を太くすることができることによ

。この発明では、軸２２．２２の径を広くできるので、
それに応じてアーム２１．２１の幅を広くしてアーム２
１．２１の強度を増すことができる。Furthermore, since the shaft 22.22 can be made thicker, the thickness near the tip of the arm 21.21 can also be made thicker accordingly. If the width of the tip of the arm 21.21 was wider than the diameter of the shaft 22.22, the movement of the assembled blade 1 would be restricted, so it could not be made wider than the diameter of the shaft 22.22. In this invention, since the diameter of the shaft 22.22 can be increased,
Accordingly, the width of arm 21.21 is widened and arm 2
1.21 strength can be increased.
本発明は軸２２．２２やアーム２１．２１を太くしてな
お且つ揺動軸線を刃面に近づけることができるので、組
立刃体１の円滑な揺動を提供できる優れた発明である。The present invention is an excellent invention that can provide smooth rocking of the assembled blade body 1 because the shaft 22.22 and the arm 21.21 can be made thicker and the rocking axis can be brought closer to the blade surface.

かみそり。Consisting of an assembled blade body 1 and a holder 20, the assembled blade body 1 is attached to the holder 20 so as to be able to swing around a swing axis extending in the longitudinal direction, and the assembled blade body 1 is elastically The means for returning the blade to its original position is the assembled blade 1.
In the safety razor interposed between the journal shafts 22, 22 and their bearings 7, 7, the cross-sectional shapes of the journal shafts 22, 22 and their bearings 7, 7 are circular with their upper portions cut out, so that the journals have a perfectly circular cross-section. A safety razor characterized in that the axis of swing is closer to the blade surface than when a shaft is used.
