DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair scissor scissors in which two blades, a flat blade and a comb-shaped blade, are pivotally connected to each other so that the blades are rubbed against each other.

[0002]

2. Description of the Related Art In general, a comb-type scissors of this type, in which a flat blade-shaped blade is used as a stationary blade and a comb-shaped blade is used as a moving blade, is closed by a comb-shaped blade when a moving blade applied to hair is closed. It is used to cut a part of the hair while stopping the slipping of the hair hitting the cutting edge, and to adjust the hair while allowing a part of the hair to escape into a cutting groove forming a cut-off portion.

In this type of scissors, in which the length of the hair to be cut is increased or decreased, the width of the cutting groove becomes relatively large, and the width of the comb-shaped blade becomes relatively small, so that the cutting blade occupies the blade. As the proportion of the length of the part is reduced, the amount of hair that can be cut with one scissor is reduced, and the difference between the cut and the uncut part becomes noticeable, so use small scissors Will be required.

On the other hand, if the flat blades are rubbed with each other by omitting the use of a comb-shaped blade, the amount of hair that slides on the blade at the time of cutting is increased, and the length of the hair cut at the hand side of the scissors and the length of the tip side are reduced. Since the difference between the length of the hair and the length of the cut hair is formed, the effect of the comb scissors that cuts the hair with a certain difference in length without increasing the number of times of using the scissors is lost.

For this purpose, for example, in the comb scissors disclosed in Japanese Patent Publication No. 6-159, individual cutting blades forming a comb-shaped blade are formed in a Y-shape, and the width of the blade edge is made as large as possible. By increasing the ratio occupied by the length of the cutting edge of the cutting edge, while reducing the entrance width of the notched edge formed between each cutting edge, and by rapidly increasing the back width , While the hair is prevented from slipping by the V-shaped concave cutting edge, the hair cut efficiently with the wide cutting edge, and the hair escaping into the narrow cutting edge is guided into the expanding space, and Clogging and pinching on the sliding surface are eliminated, but the Y-shaped cutting blade
The amount of hair caught by the part is large, and it should be cut at the back of the recess
Therefore, the cutting resistance is increased, and the work of using the scissors is increased, resulting in a disadvantage that fatigue is easily caused.

[0006]

In view of the above, the comb-shaped cutting edge portion is designed to be as close as possible to a flat blade shape so that the length of each cutting edge in contact with the hair is increased and the cutting edge at the time of cutting is increased. While allowing the escape of hair to reduce cutting resistance, increasing the ratio of the length of the cutting edge smoothly guides the hair in the narrow cut groove, such as clogging by the escaped hair. It is to prevent the pinching of the thread each other surface has been a problem to be solved and have you in this kind of Kezu鋏.

[0007]

SUMMARY OF THE INVENTION Accordingly, the present invention relates to a hair-dressing comb scissors in which a flat blade-shaped blade and a comb-shaped blade are connected to be openable and closable such that their blades are slid together by a pivot shaft. grooves cut to form the cutting portion to the tool of the comb teeth are open to the sides of the blade to the inner end, than the groove width of the cut recess Ru with a circular hole of large diameter. Notch grooves on both sides
