Description

  The present invention relates to a clipper blade including a fixed blade and a movable blade, and an electric clipper provided with the clipper blade.

  Conventionally, the hair introduced between the blades of the movable blade can be moved by overlapping the comb-shaped fixed blade and movable blade formed by arranging a plurality of blade bodies, and reciprocatingly sliding the movable blade with respect to the fixed blade. There is an electric clipper that is sandwiched between a blade and a fixed blade and cut.

For example, in the electric clipper disclosed in Patent Document 1, the gap in the juxtaposed direction of the blades of the movable blade differs depending on the position in the longitudinal direction of the blade of the movable blade (orthogonal direction orthogonal to the juxtaposed direction of the blades). It is like that. Specifically, a wide blade is formed on the tip side in the longitudinal direction of the blade body of the movable blade so as to spread in the juxtaposition direction, and the gap in the juxtaposition direction on the tip side of each blade body is compared. Narrow. Therefore, the hair introduced between the blades of the movable blade tends to stay between the blades, and the hair is prevented from escaping from the tip side between the blades.

  However, in the electric hair clipper described above, since the blade body is formed so that the wide blade portion is provided and the gap in the juxtaposed direction on the tip side between the blade bodies of the movable blade is narrowed, when introducing hair, There is a problem that the hair comes into contact with the wide blade portion on the tip side of the blade body of the movable blade, and the hair to be introduced is difficult to be introduced between the blade bodies.

  The present invention has been made in order to solve the above-described problems, and the object thereof is to adopt a shape of a blade body that suppresses escape of hair introduced between the blade bodies of the movable blade, and between the blade bodies. An object of the present invention is to provide a clipper blade and an electric clipper that can improve the hair introduction property.

  In order to solve the above-mentioned problem, the invention according to claim 1 is characterized in that a plurality of blade-shaped fixed blades and a plurality of blade-shaped blades are arranged side by side, and a plurality of blade bodies are arranged in parallel to the fixed blade. A hair clipper blade having a comb-shaped movable blade configured to be reciprocally slidable and configured to cut hair with the blade body of the fixed blade and the blade body of the movable blade sandwiched in the sliding direction. The blade body of the movable blade is formed with cutting blade portions on both sides, and one of the opposed cutting blade portions of the adjacent blade body is at least the adjacent blade on the tip side of the blade body. Formed as a first cutting blade portion inclined toward the body side, and the other of the opposing cutting blade portions of the adjacent blade body is opposite to the adjacent blade body from the base end to the tip end of the blade body The gist is that it is formed as a second cutting edge portion inclined toward the surface.

  In this invention, the blade body of the movable blade is formed with cutting blade portions on both sides, and one of the opposing cutting blade portions of the adjacent blade body is inclined toward the adjacent blade body side at least on the tip side of the blade body. The second cutting edge portion is formed as a first cutting edge portion, and the other of the opposing cutting edge portions of the adjacent blade body is inclined from the proximal end to the distal end of the blade body toward the opposite side of the adjacent blade body. It is formed as a cutting edge part. For this reason, the introduced hair is liable to stay between the blade bodies by the first cutting blade portion inclined toward the adjacent blade body side on the distal end side of the blade body, and the escape of the hair can be suppressed. Furthermore, as compared with the blade body in which the wider blade portion is formed so as to be closer to the tip side of the blade body as in the prior art, the second cutting blade portion is inclined toward the opposite side to the adjacent blade body. By being formed, the gap between the blade bodies on the tip side of the blade bodies can be widened, and the introduction of hair between the blade bodies can be improved.

  According to a second aspect of the present invention, in the hair clipper blade according to the first aspect, the blade of the movable blade has a first cutting edge portion on one side and a first cutting edge portion on the other side. The gist is that it is composed of two cutting edges.

  According to the present invention, it is possible to suppress the escape of hair and the blade with a movable blade having the same shape of the blade with the first cutting edge portion being the first cutting edge portion and the other cutting edge portion being the second cutting edge portion. It is possible to improve the hair introduction property between the bodies.

  According to a third aspect of the present invention, in the hair clipper blade according to the first aspect, the blade body of the movable blade includes first and second blade bodies that are alternately arranged, and the first blade body is formed on both sides. Both of the first and second cutting blade portions are configured, and the second blade body has both the cutting blade portions on either side of the first and second cutting blade portions. It is made up of that.

  In this invention, the 1st blade body of the line symmetry shape which has the 1st cutting blade part on both sides, and the 2nd blade body of the line symmetry shape which has the 2nd cutting blade part on both sides are comprised by turns. With the movable blade, it is possible to suppress the escape of the hair and improve the introduction of the hair between the blade bodies.

Inclined linearly toward the opposite side and linearly inclined toward the adjacent blade body side from the intermediate portion to the tip, and the second cutting edge portion is inclined linearly The gist is that it is formed.

  In this invention, the first cutting edge portion is inclined toward the opposite side of the adjacent blade body from the base end to the intermediate portion of the blade body, and is inclined toward the adjacent blade body side from the intermediate portion to the distal end. The second cutting edge is formed so as to incline linearly. Thereby, for example, the scissors angle formed by the first and second cutting blade portions of the blade body of the movable blade and the cutting blade portion of the blade body of the fixed blade can be easily made constant at an appropriate angle.

  According to a fifth aspect of the present invention, in the hair clipper blade according to the fourth aspect, the first and second cutting blade portions have a full scissor angle formed by the cutting blade portions provided on both sides of the fixed blade. The gist is that they are formed to be the same in the cutting edge region.

  In the present invention, the first and second cutting edge portions are formed so that the scissor angle formed by the cutting edge portions provided on both sides of the fixed blade is the same in the entire cutting edge region. Thereby, the cutting ability can be easily improved by setting the scissor angle to an appropriate angle (in the range of 0 to 40 degrees, particularly in the vicinity of 20 degrees).

The gist of the invention described in claim 6 is that the movable blade is configured by alternately arranging a blade body having a short length and a long blade body in the orthogonal direction orthogonal to the juxtaposed direction.
In this invention, since the movable blade is configured by alternately arranging the blades having a short length in the orthogonal direction orthogonal to the juxtaposed direction and the blades having a long length, the movable blade is arranged to the tip of the blade body having a short length in the orthogonal direction. After being introduced, it becomes possible to cut the hair located at the tip of the short blade with a long blade, which can contribute to the improvement of the cutting ability for cutting the hair.

  The invention according to claim 7 is the clipper blade according to claim 6, wherein the short blade has the second cutting edge, and the tip of the second cutting edge of the short blade. The length in the orthogonal direction of the short blade body is set so that the perpendicular line at the corner portion is a position passing the proximal end side from the tip corner portion of the first cutting blade portion of the long blade body. The gist.

  In this invention, the short blade body is provided with the second cutting blade portion, and the perpendicular at the tip corner portion of the second cutting blade portion of the short blade body is longer than the tip corner portion of the first cutting blade portion of the blade body. The length in the orthogonal direction of the short blade body is set so that the position passes through the base end side. Thereby, for example, when the hair is bounced without being cut by the second cutting blade portion of the short blade body by reciprocating sliding in the direction in which the movable blades are arranged side by side, the hair is moved in the vertical direction of the second cutting blade portion. Therefore, the repelled hair is likely to be positioned closer to the base end side than the distal end (front end corner portion) of the first cutting blade portion of the long blade body. Therefore, it is possible to suppress the escape of hair bounced by the second cutting blade portion of the short blade body.

The gist of the invention described in claim 8 is that it comprises the clipper blade according to any one of claims 1 to 7 and a drive source for moving the movable blade of the clipper blade.
In this invention, the clipper blade according to any one of claims 1 to 7 and a drive source for moving the movable blade of the clipper blade are provided, so that any one of claims 1 to 7 is provided.
