を改良した電気かみそりの刃に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric shaver blade, and more particularly to an electric shaver blade having an improved structure of a fixed blade and a movable blade that slide back and forth.

Description of the Related Art Conventionally, in a blade of an electric razor such as a trimmer in which a fixed blade and a movable blade, which are almost comb-shaped, slide reciprocally, the fixed blade and the movable blade are generally formed in a plane and are superposed. The tip edges of these blades are formed in a straight shape or a convex shape protruding forward from both end portions of the blade width to the central portion.

けるおそれがあった。The blade of such an electric razor can efficiently shave hair when the part of the body that hits the blade is generally flat or concave, as in the case of shaving the hair under the armpit, but as shown in FIG. There is a problem in that a gap is formed between the body part 52 and the blade 51 with respect to the arm or leg where the body part 52 is a convex curved surface, which is inefficient and requires a long time for shaving waste. At the same time, if the blade 51 is strongly pressed against the body surface part 52 in order to improve efficiency, the blade 51 may bite into the skin and be damaged.

に形成したものである。In order to solve such a problem, for example, JP-A-56-97480 and JP-A-53-20672 have been already proposed. Of these, JP-A-56-97480 is for adjusting the eyebrows, and the tip edge of the blade is formed into a convex or concave shape to match the shape of the eyebrows.
No. 672 is a blade for haircut and is formed in a concave shape according to the shape of the head.

よく完全に除去することは不可能であった。However, since all of these blades are flatly formed, even if they are diverted to use for dead hairs of arms and legs, the blades contact the body part depending on the angle of contact with the skin. Since the contact length of the hair was changed, it was impossible to remove the waste hair efficiently and completely.

る、という問題がある。Therefore, it is conceivable to bend the so-called trimmer blade in the sliding direction so as to match the concave portion and the convex portion of the body part, but in this case, the blade is curved in the entire sliding direction. If the movable blade and the fixed blade are not brought into close contact with each other without a gap, the sharpness becomes poor, and the sliding resistance is partially concentrated to increase the load, resulting in a large noise.

騒音の小さい電気かみそりの刃を提供することにある。The present invention has been proposed in view of the above points, and an object of the present invention is to bend a fixed blade and a movable blade instead of a planar shape so that the blades overlap with each other to form a curved movable blade.
An object of the present invention is to provide a blade of an electric razor that has a fixed blade in close contact with the entire area and has excellent sharpness and low noise.

And the curved contact surfaces of the fixed blade and the movable blade are curved in the sliding direction to be overlapped, and the relationship between the radius of curvature of the movable blade and the radius of curvature of the fixed blade is located on the protruding direction side. The above-mentioned object is achieved by setting the radius of curvature of the blade to be smaller than the radius of curvature of the other blade.

Keeping the radius of curvature smaller than that of the blade, the blade with the smaller radius of curvature is pressed against the other blade during assembly and deforms along the curved shape of the other blade, so both blades are in close contact over the entire area. It is designed to be sharp, sharp, and quiet.

Ｒ2 に設定されている。この理由については後述する。However, when the sliding contact surfaces of the fixed blade 8 and the movable blade 9 are curved in the sliding direction and overlapped with each other, the curvature radius R 1 of the movable blade 9 and the curvature radius R 2 of the fixed blade 8 are The relationship is such that the radius of curvature of the blade located on the projecting direction side is smaller than the radius of curvature of the other blade. That is, in the example shown in FIG. 3, the fixed blade 8 and the movable blade 9 are formed so as to project downward and are curved, and in this case, the fixed blade 8
And the relationship between the radii of curvature R 2 and R 1 of the movable blade 9 is R 1 >
It is set to R 2 . The reason for this will be described later.

いる。However, in this embodiment, as shown in FIG. 4 (a), the blade tip edges 35 and 34 of the movable blade 9 and the fixed blade 8 are formed in a concave shape toward the front, and in FIG. As shown in, the sliding contact surfaces 28 and 25 of the movable blade 9 and the fixed blade 8 are formed so as to curve downward at the central portion thereof, in other words, the fixed blade 8 and the movable blade 9 are orthogonal to the sliding direction. And the radius of curvature R 1 of the movable blade 9 and the radius of curvature R 2 of the fixed blade 8 are smaller than the radius of curvature of the other blade. And it has a configuration.

せ、切れ味を良くし、かつ騒音を小さくさせている。In the above, when the sliding contact surfaces 28 and 25 are curved in a concave shape, it is conceivable to form and grind along the direction of arrow A in the fixed blade 8 of FIG. In this case, if the radii of curvature R 1 , R 2 of the sliding contact surfaces 28, 25 do not match, a gap is created in the sliding contact surfaces 28, 25, and the sharpness deteriorates. Therefore, in order to bring the sliding contact surfaces 28 and 25 into close contact with each other while setting the grinding accuracy relatively rough, the radius of curvature R 2 of the fixed blade 8 is set to the radius of curvature R 1 of the movable blade 9 as described above.
When the size is made smaller, when assembled, the movable blade 9 is brought into close contact with the fixed blade 8 by pressing one or a plurality of locations near the central portion of the movable blade 9 in the direction of the fixed blade 8 by the push-up spring 29. In this way, the sliding contact surfaces 28 and 25 are brought into close contact with each other to improve sharpness and reduce noise.
