Abstract

PROBLEM TO BE SOLVED: To provide a pair of combing scissors capable of preventing hair from being damaged and performing smooth haircut work. SOLUTION: In this pair of combing scissors, two cutters, that is, a cutter having a straight-flute knife edge and a comb-tooth cutter having alternations of a cutting blade part 4 and a partially missing cutting blade part 5 at the knife edge are connected to be freely opened and closed by a pivot shaft to rub each other. The corner part of the bottom 5' of the partially missing cutting blade part of the comb-tooth cutter is rounded.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blade having a straight blade and a comb-shaped blade having a cutting edge and a cutting edge alternately on the blade so that two blades rub against each other. The present invention relates to barber scissors for hairdressing and beauty, which are used to open and close freely with a pivot shaft, and mainly for combing hairy portions to finish hair with a light or soft feel.

[0002]

2. Description of the Related Art A barber or cosmetic comb scissors is composed of two blades, namely, a blade having a straight blade and a comb-shaped blade having a cutting edge portion and a cutting edge portion alternately. It has a structure in which it can be freely opened and closed by a pivot shaft so as to rub against each other.

In the above-mentioned comb scissors, the hair is cut only at the portion where the cutting edge of the comb-shaped blade and the cutting edge of the straight blade are rubbed, and the remaining hair is cut off at the comb-shaped blade. The amount of hair is reduced by being left in the section and left uncombed (that is, not cut).
There is a problem that hair is easily damaged when hair is cut using comb scissors.

[0004] This is considered to be due to the fact that a large amount of hair is pushed into the missing blade portion of the comb-shaped blade so that the entered hair strongly rubs against the bottom surface, wall surface and the like of the missing blade portion. .

[0005] In particular, in the conventional comb scissors, as shown in FIG. 3, the bottom surface (15 ') of the cutting edge (15) of the comb-tooth-shaped blade is connected to the side surface (15) of the cutting edge (15). 17) and a corner (18) having a substantially right-angled cross section. When the surface of the hair is rubbed with the sharp corner (18) or when the scissors are closed (when cutting), the corner (18) is formed. It is thought that the moment when the hair comes into contact with 18) and a strong force is applied momentarily is the biggest cause of damage to the hair.

[0006] If the scissors can be always vertically applied to the hair, it is considered that there will not be much problem. However, such a problem is usually impossible, and especially in the recent barber / beauty industry. At the time of haircut, the scissors tend to move much faster than before, and it is considered that the hair is more severely damaged in such a fast-moving operation. On the other hand, there is also a problem that the hair is caught on the corner and cannot be moved smoothly even if it is desired to move the scissors quickly.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above, and an object of the present invention is to provide comb scissors in which hair is not easily damaged during hair cutting. Further, it is an object of the present invention to provide a comb scissors in which the scissors do not catch on the hair, and thus can move the scissors faster and more smoothly.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a comb scissors according to the present invention comprises: a cutting tool having a straight-edged cutting edge;
Comb-type scissors in which two blades, a comb-shaped blade having a cutting edge portion and a notched blade portion alternately at a blade edge, are connected to each other so as to rub against each other and can be freely opened and closed by a pivot shaft. It is assumed that the corner of the bottom surface of the cutting edge of the blade has a rounded shape (claim 1).

It is preferable that the bottom surface of the cut edge portion of the comb-shaped blade is substantially arc-shaped in cross section.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings, but the present invention is not limited thereto.

FIG. 1 is a plan view showing an embodiment of the comb scissors according to the present invention.

As shown in the figure, the comb scissors of the present invention are similar to conventional comb scissors, and have a blade having a straight blade edge (2) (hereinafter also referred to as a straight blade) (1). And a comb-shaped blade (3) having a cutting edge (4) and a cutting edge (5) alternately at the cutting edge. These two blades (1) and (3)
They are connected to each other so as to freely open and close by a pivot shaft (6) so as to rub against each other.

The shape of the cutting tool (1) having the straight cutting edge (2) may be exactly the same as that of the conventional scissors.

In the comb-shaped blade (3), cutting blades (4) are formed at substantially equal intervals on the side of the straight blade-shaped blade (1) facing the blade edge (2). Therefore, between each cutting edge part (4) and the cutting edge part (4), a cutting edge part (5) having substantially the same width is formed. The shape and thickness of the cutting edge portion (4) and the interval between them (that is, the width of the cutting edge portion (5)) are not particularly limited, and may be the same as conventional ones.

FIG. 2 is a partially enlarged cross-sectional view showing the cutting edge portion (4) and the cutting edge portion (5) of the comb-shaped blade (3) along the line AA in FIG.

As shown in this figure, the shape of the cutting edge (4) is the same as that of the conventional one, but the shape of the bottom (5 ') of the cutting edge (5) is substantially circular in cross section. , And is smoothly connected to the side surface (7) of the blade (3). That is, on the bottom surface (5 ') of the cutting edge portion (5) of the comb scissors,
As shown in FIG. 3, the bottom surface (1)
There is no corner as in 5 ').

Since the bottom surface (5 ') of the cutting edge (5) has the above-described shape, the comb scissors of this embodiment can be cut at any angle against the hair. The hair that has entered the blade portion (5) abuts on the gently curved bottom surface (5 '), and does not abut on the sharp corner of the bottom surface as in the prior art. Therefore, the conventional hair is not damaged.
Moreover, the scissors are not caught, and the haircut operation can be performed more smoothly.

Note that the shape of the bottom surface of the cutting edge portion (5) is not limited to the above-described substantially arc-shaped cross section, and can be appropriately changed within a range in which the object of the present invention can be achieved. In other words, the bottom surface of the notched blade portion may have a rounded shape so that the hair is not caught by the hair, and as long as this condition is satisfied, for example, it may have a cross-sectional shape close to a trapezoid. Good.

[0019]

According to the card scissors of the first aspect, since the bottom edge of the cut-off portion is rounded, the hair is not caught as in the prior art, and therefore it is hard to damage the hair at the time of haircut. In addition, the haircut work can be performed more smoothly.

In particular, when the bottom surface is formed to have a substantially arc-shaped cross section, the above-mentioned effect is remarkably obtained.
