この考案は特に二枚刃安全剃刀において刃体の
刃先の位置決め構造に関するものである。[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) This invention particularly relates to a structure for positioning the cutting edge of a blade body in a two-blade safety razor.

作業に際して大変重要である。(Problems to be solved by conventional techniques and ideas) As a conventional two-blade safety razor,
There is one shown in No. 168273 and another shown in Japanese Patent Application No. 124195-1983. For example, with the former two-blade safety razor,
Upper and lower blade bodies are held between the blade stand and the cover via a spacer, and the cutting edges of the upper and lower blade bodies protrude to the vicinity of the shaving tangent plane connecting the cover and the guard on the front side of the blade stand. The position of the cutting edge relative to the shaving tangential plane and the mutual positional relationship between the cutting edges of the upper and lower blade bodies have a subtle effect on the shaving quality, and are therefore very important when assembling a safety razor.
通常、二枚刃安全剃刀の組立作業においては、
刃台上に下刃体、スペーサ、上刃体及びカバーを
順次重ね合わせ、上下両刃体の後側を特別な押え
具で押えて上下両刃体の刃先の左右両側をカバー
の左右両側のストツパ面に当接させた状態で、カ
バーを刃台に固定していた。ところが、特別な押
え具を必要とするため、組立作業が大変面倒であ
つた。 Normally, when assembling a double-blade safety razor,
Lay the lower blade, spacer, upper blade, and cover on the blade stand in sequence, and press the rear sides of the upper and lower blades with a special holding tool, and press the left and right sides of the cutting edges of the upper and lower blades to the stopper surfaces on both the left and right sides of the cover. The cover was fixed to the blade rest with the cover in contact with the blade. However, since a special holding tool was required, assembly work was very troublesome.
又、この刃体位置決め構造では、上下両刃体が
カバーのストツパ面に当接した状態で、ひげ剃り
接線面に対する刃先の位置や上下両刃体の刃先の
相互位置関係が最適なものになるようになつてい

うな場合には、上下両刃体の刃先が後方へずれて
刃先の位置を最適な状態に保持することができな
くなり、剃り味に悪影響を及ぼすこともある。 In addition, with this blade positioning structure, when the upper and lower blades are in contact with the stopper surface of the cover, the position of the blade with respect to the shaving tangent surface and the mutual positional relationship between the blades of the upper and lower blades are optimized. However, in the unlikely event that the blade rest and cover become loose, the cutting edges of both the upper and lower blades will shift backwards, making it impossible to maintain the optimum position of the cutting edges. It may also have a negative effect on the quality of the shave.

a, 15a are always in contact with the stopper surfaces 14, 13 due to the elasticity of the leaf springs 7, 6, so that the blade edges are not aligned with the shaving tangent plane P connecting the guard 9 of the cover 3 and the clamping portions 11, 12. 15a, 16a are accurately positioned, and the upper and lower double blade bodies 16, 15
The mutual positional relationship between the cutting edges 16a and 15a is also set accurately. Furthermore, unlike the prior art, no special presser is required during assembly, which greatly facilitates assembly. Furthermore, even if loosening occurs between the blade rest 2 and the cover 3, the loosening can be tolerated within the range of deflection of the leaf spring parts 6 and 7, thereby preventing swinging of the upper and lower blade bodies 16 and 15. be able to.
