Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Field of Industrial Application) The present application relates to the structure of the attachment of a T-shaped razor blade and a holder.

(Prior Art) A T-shaped razor is configured to be replaceably attached to a holder by fitting a thick and/or thin mounting portion of the blade into a mounting groove in the holder. be. Alternatively, as in Japanese Utility Model Application No. 49-136490, a blade mounting member is provided on the blade body, and the proximal bulge provided on the blade mounting member is fitted into the mounting groove of the holder. There is something. Conventionally, in a cutlery configured in this way, the blade body has a thick wall and/or a mounting portion, etc.
Alternatively, when forming a thin walled portion, a metal plate having a uniform thickness as a whole is pressed or cut. or,
In the case where a blade attachment member is provided, the proximal end must be curved to provide a bulge.

However, forming the blade body in this way not only complicates the manufacturing process, but also causes problems such as the thickness of the machined part becoming uneven and the surface becoming rough. I couldn't build a body. Furthermore, when the blade was attached to the holder, a gap was created between the blade and the mounting groove of the holder, making it impossible to reliably assemble the two. Further, in the case where a blade attachment member is provided, there is also a problem that the number of parts for this purpose increases.

(Problems to be Solved by the Invention) Therefore, in the present application, when forming thick and/or thin wall parts on the blade body, not only does the manufacturing process become complicated, but also the plate thickness of the machined part of the blade body is insufficient. Solved the problem of not being able to create a highly accurate blade due to uniformity or roughness of the surface, which in turn made it impossible to securely attach the blade to the holder, and the problem of an increase in the number of parts. It is for the purpose of

Structure of the Invention (Means for Solving the Problems) In order to solve the above problems, in a T-shaped razor, a mounting groove is formed by a blade rest of a holder and an upper plate located above the blade rest. , two blade bodies each having a thick wall portion and a thin wall portion are produced by processing an irregularly shaped plate that has a thick wall portion and a thin wall wall portion, and has high plate thickness accuracy and surface finish accuracy. The two blade bodies are superimposed and held in the mounting groove.
