Abstract

(57) [Abstract] [Purpose] The blade part of the carding blade was formed into a flat blade type with excellent sharpness, and the escape of hair caused by the carding blade of the flat blade type was suppressed especially at the hand side of the blade part. Make card scissors easy to manufacture and suitable for mass production. [Structure] The cutting blade 1 is formed by forming an inclined flat blade 8 in which the blade tip 6 is inclined to one side from the hand side to the middle of the blade portion 4 of the carding blade 3.
The contact angles of the blades with the blade portions 2 were set to be close to parallel to each other.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a carding scissor having a blade having a straight blade shape as a cutting blade, and the blade part is opened and closed with respect to a combing tooth-shaped carding blade and used for hairdressing.

[0002]

[Prior art]

 As for this kind of carding scissors mainly used in barber shops and the like, for example, Japanese Patent Application No. 3-114292 is a prior application of the applicant.

[0003]

[Problems to be solved by the device]

 The comb-shaped comb-shaped blade having a flat blade-type blade has a drawback that the hair easily escapes from the cutting edge when the cutting blade slides on the straight blade-shaped blade. In order to eliminate this drawback, V-shaped or U-shaped blades with V-shaped or U-shaped cutting edges are used, but these conventional products reduce the escape of hair. Since the hair caught in the cutting edge is gathered in a bundle and cut at one time, the cutting resistance becomes large and the hair is easily damaged at the cut end.

In view of the above, the applicant of the present invention, in the above-mentioned prior application, in the flat blade type carding blade by gradually reducing the length of the blade on the hand side so that the blade line formed by the blade part of the carding blade is curved. We proposed a carding scissor that suppresses the escape of hair as much as possible and increases the cutting rate.

In the above-mentioned prior application, the angle at the time of sliding between the blade portion of the cutting blade and each blade of the carding blade, that is, the sliding angle becomes large on the hand side of the scissors. In the case of carding blades, paying attention to the high rate of hair escape from the cutting edge, set the length of each carding blade to reduce the sliding angle formed at the relevant part, and adjust the length of each blade By shortening the length of the blade and gradually increasing the blade length toward the middle of the blade, the sliding angle between the blade tip of each blade and the blade of the cutting blade is formed to be small on average, which helps the escape of hair. I tried to keep it low.

However, the carding blade of the above-mentioned prior application is difficult to form when a blade having a short blade length is formed on the side of the scissors, is not suitable for mass production, is expensive, and has a short blade length. There was a technical problem that it was difficult to achieve sharpness.

From the above, the blade portion of the carding blade is formed of a flat blade having good sharpness, and the escape of the hair from the tip which occurs in the carding blade of the flat blade type is suppressed to a low level, and it can be easily produced. Doing so remained a problem to be solved in this kind of card scissors.

[0008]

[Means for Solving the Problems]

 Therefore, the present invention provides a carding scissor including a cutting blade having a straight blade-shaped blade portion and a carding blade having a comb tooth-shaped blade portion, wherein the blade portion of the carding blade forming the comb tooth shape is It is equipped with inclined flat blades that are inclined so that the blade length becomes shorter on the side surface on the proximal side of the scissors, at least from the proximal side of the scissors to the middle of the blade section. The blade is formed so that the angle of inclination is increased on the hand side of the blade so as to approach the direction parallel to the sliding angle of the blade, and the angle of inclination is gradually reduced toward the middle of the blade. It provides scissors.

[0009]

[Action]

 As described above, the inclined flat surface is designed so that the side surface on the proximal side is shortened from the proximal side of the scissors to the portion reaching the middle of the blade, and the inclined angle is increased on the proximal side. Compared with conventional scissors, the carding scissors of the present invention in which the blade is provided on the blade of the carding blade have a small sliding angle with the cutting blade side compared to conventional scissors, even if the blade length is not particularly short on the hand side. It becomes a sharp angle and it is easy to catch the hair to be cut.

Therefore, it is possible to maintain the sharpness of the blade portion of the flat blade type, which is optimal for cutting hair, and at the same time, it is possible to perform the same molding process as that for forming a normal carding blade, which facilitates production. The present invention solves the above problems as described above.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. In the figure, 1 is a cutting blade in which a blade portion 2 is formed in a straight blade shape, 3 is a carding blade in which a blade portion 4 is formed in a comb tooth shape, and 5 is a cutting blade 1 and a carding blade 3 which are pivotally attached so as to be openable and closable. A pivot shaft P0 provided so as to slide the blade portions 2 and 4 together is an intersection angle between the blade edge line L1 of the cutting blade 1 and the blade edge line L3 formed by the blade portion 4 on the carding blade side.

As shown in FIG. 2, the blade portion 4 of the carding blade 3 is formed by a normal flat blade type blade 7 in which the blade edge 6 is aligned with the blade edge line L3 from the tip to the middle of the scissors. From the end to the hand side of the scissors, the blade tip 6 is formed by an inclined flat blade 8 inclined to one side.

Each of the inclined flat blades 8 has a blade edge 6 that is inclined so that the length up to the blade edge 6 becomes short on the side surface on the proximal side. Further, as shown in FIG. 3, the inclination angle pn of each blade edge 6 is set so that the angle on the hand side of the blade portion 4 is large, and the inclination angle pn is gradually reduced toward the middle of the blade portion 4. There is.

As shown in FIG. 4, the inclination angle pn of the inclined flat blade 8 provided as described above is the sliding angle Ln with the cutting edge line L1 of the cutting blade 1 formed for each cutting edge 6. So that they approach each other almost parallel to each other. Therefore, the escape of hair, which is particularly likely to occur in the blade portion 2 of the carding blade 3 from the proximal side where the inclined flat blade 8 is provided to the middle, is suppressed, and the sharpness of the flat blade blade portion can be sufficiently exhibited.

In implementing the present invention, although not shown, an inclined flat blade may be provided over the entire length of the blade portion of the carding blade.

[0016]

[Effect of device]

 According to the present invention in which the inclined flat blade is provided on the blade of the carding blade as described above, the sliding angle between the cutting blade and the blade of the carding blade is small from the hand side of the scissors to the tip. Since an acute angle is formed, the amount of hair cut is averaged over the entire length of the blade portion, and carding scissors having excellent sharpness can be used.

Further, according to the present invention, as shown in the drawing, a flat-blade type carding blade having a blade length substantially the same as that of a normal carding scissor can be manufactured, which facilitates the processing technique. It has many practical effects such as being suitable for mass production.
