Abstract

PROBLEM TO BE SOLVED: To make it possible to impart an unevenness at the tip of cut hair of by forming the comb blade by combining a straight blade of which the blade tip is rectilinear, and a recessed-form blade of which the blade tip has a recessed curved-form, and the heights of respective blades of both blades are made uneven, scissors for hairdressing, wherein a comb blade and a bar blade are pivotally attached. SOLUTION: For scissors for hairdressing wherein a comb blade and a bar blade are connected by a spindle, respective blades of the comb blade are formed in such a manner that straight blades 14 having a rectilinear blade tip, and recessed-form blades 15 which are curved into a recessed-form, are alternately arranged, and the blade tip of each linear blade 14 is provided in a manner to be an approx. rectilinear form, and in the meantime, the height of respective recessed-form blades 15 are variously set. That is, the recessed-form blades 15 have steps by various heights, but every recessed-form blade 15 is made lower than the linear 14. Also, the line of each blade tip of the linear blade 14 meets the line of blades which is formed as a bar blade, even if the comb blade is a bar blade, and by forming the linear blades in such a manner that the linear blades tilt based on a reference blade line so that the crossing angle with the blade of a closing bar blade may become smaller, the slipping off of hair is suppressed, and the cutting sharpness becomes favorable.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to hairdressing scissors.

[0002]

2. Description of the Related Art In general, cut scissors mainly used for forming a hair style and carded scissors used for adjusting the amount of hair are known as hairdressing scissors. Cutting scissors are equipped with two bar blades, and comb scissors are comb-shaped blades (hereinafter
A comb blade) and a bar-shaped blade (hereinafter, referred to as a bar blade).

[0003] In general, the tip angle (angle in the thickness direction of the blade) of a bar blade of cutting scissors is sharpened to about 35 ° in consideration of its sharpness, whereas the comb blade of combing scissors is sharpened. Considering the strength of each blade at the time of processing, it is difficult to grind to a sharp edge angle as sharp as a bar blade of cutting scissors, and it is said that combing scissors do not require sharpness as sharp as cutting scissors. From the point of view, the included angle was set to about 60 to 80 °. By the way, in recent years, by using advanced machining technology such as electric discharge machining or NC machining, it should be possible to machine even a single comb blade with a sharp edge angle.
In fact, while using such a processing technique, the shape of the conventional cutting edge has been followed without asking any questions.

In general, in cutting scissors, the bar blades are straight blades, and the bar blades reciprocately rotate and pinch the hair bundle between them to shear, so that the bar blades intersect each other. The point (shear point) moves radially outward in the rotation, and the shearing proceeds. In such a shearing mechanism, the hair is sheared so as to escape while being pushed radially outward.However, in the case of combing scissors, if the same mechanism of straight blades is used, the hair escapes from between both blades. The cut hair enters the gap between the comb blades so that the hair cannot be cut. In order to avoid such inconvenience, the cutting edge of each of the comb blades of the comb scissors is formed in a concavely curved shape as shown in an enlarged view in FIG. Therefore, the bristle bundle once sandwiched between the straight blade of the bar blade and the concave blade of the comb blade does not escape from between the two blades, that is, without escaping into the gap between the comb blades. She is caught and sheared in between. Of course, the hair that had entered the gap between the comb blades from the beginning is not sheared.

[0005] The cutting scissors and the combing scissors each having the above-mentioned characteristics are all combined in a hair style.
It has been developed as suitable for techniques based on the traditional haircut theory, such as trimming. And
Conventional carding scissors have a large edge angle as described above, and therefore have no sharpness for use as cutting scissors, and cannot be used as cutting scissors.

By the way, the applicant of the present invention has proposed that
The scissors, which are formed by alternately arranged straight blades and concave blades and look like combing scissors having comb blades, have both cutting and combing scissors.
No. 5 discloses this. The scissors may also be used by professional hairdressers or barbers to move at high speed to form hair styles like cut scissors.
While cutting the hair at high speed using these scissors, the cutting position is gradually moved from the root of the hair to the tip of the hair, and the cut hair is cut like the case with conventional cutting scissors. Instead of the lines being arranged substantially linearly, a natural expression having a moderate variation (irregularity) comes to appear. The names of the cutting scissors and the carding scissors are named based on their uses, but since their shapes are apparently different at first glance, they tend to be called by being distinguished from their shape characteristics. JP-A-8-7
Although the scissors disclosed in No. 1265 are combing scissors based on this shape characteristic, the scissors have both functions of cutting scissors and combing scissors in terms of use and function.

[0007]

The scissors and other hairdressing tools used so far have been developed as suitable for techniques based on the traditional haircut theory, such as combining and trimming hairstyles. For example, cut scissors are used to form the hair style, and the hair ends are substantially linearly aligned as described above. In addition, the comb scissors used for adjusting the amount of hair are such that every single comb blade has the same length and the same shape and are arranged at equal intervals, and only the hair cut with such comb scissors is viewed. This results in a uniform finish in which the tips of the hair are aligned. In response to such an old cutting technique, the present applicant proposes a technique based on a new haircut theory that gives a natural expression to the hair, instead of creating an artificial artificial shape for putting and trimming hair. We are developing tools for hairdressing and beauty suitable for such techniques. The present invention provides scissors suitable for giving a more natural and large variation to the tips of hairs cut based on this novel technique.

[0008]

Means for Solving the Problems The scissors for hairdressing and beauty according to the present invention are provided with the following constitutions in order to solve the above-mentioned technical problems and achieve the object. That is, in a hairdressing scissors in which a comb blade and a bar blade are rotatably connected by a support shaft, the comb blade includes a straight blade having a straight blade edge and a concave blade having a concave curved edge. The heights of the straight blades and the concave blades are different from each other.

When the comb blade and the bar blade are closed, the back surface of the blade of the bar blade is formed so that the blade edge of the bar blade contacts and crosses the blade edge of the concave blade. It is preferable to present a concavo-convex shape so as to protrude in the thickness direction at a position corresponding to the concave blade.

[0010] The arrangement of the combination of the straight blades and the concave blades is preferably an alternating arrangement.

Further, each straight blade of the comb blade may be inclined with respect to a reference blade line which is a line of a blade formed as a bar blade when it is assumed that the comb blade is a bar blade. .

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a hairdressing scissor according to the present invention will be described below with reference to FIGS.
FIG. 1 is a front view showing scissors having a configuration in which a comb blade and a bar blade are rotatably connected by a support shaft. In the figure, 11 is a comb blade, 12 is a bar blade, and 13 is a spindle. The hairdressing scissors of the present invention is basically characterized by the configuration of the comb blade 11. Comb blade 1
As shown in FIGS. 2A, 2B, and 2C, each individual blade has a straight blade 14 having a straight blade edge and a concave blade 15 curved in a concave shape, which are alternately arranged. And the cutting edges of the straight blades 14 are arranged substantially in a straight line,
The height of each concave blade 15 is set variously. FIG.
In the example of (A), the concave blades 15 have steps at various heights, and each of the concave blades 15 is lower than the straight blade 14 having a constant height. On the other hand, in the example of FIG. 2B, both the straight blades 14 and the concave blades 15 are arranged at a constant height, but the concave blades 15 are lower than the straight blades 14 by uniform steps. . Further, in the example of FIG. 2C, a concave blade 15 having the same height as the straight blade 14 (a concave blade in the center of the figure) is partially combined.

In the scissors of the above-described embodiment, one straight blade and one concave blade are alternately arranged. For example, two concave blades are arranged for one linear blade, It is also possible to arrange one concave blade for each two blades.
Also, the arrangement may be made in a random combination without regularity.

Further, the line of each cutting edge of the straight blade shown in FIG. 2 is a line of a blade formed as a bar blade if it is assumed that the comb blade is a bar blade (in this specification, this is a line of a blade). 3 (A), but as shown in FIG. 3 (A), by using a straight blade that is inclined with respect to the reference blade line so that the angle of intersection with the blade of the closing bar blade becomes small. The escape of hair can be suppressed and the sharpness can be improved. Conversely, FIG.
It is also possible to intentionally promote the escape of the hair and adjust the sharpness by taking the direction of inclination of the straight blade opposite as shown in FIG. Further, as shown in FIG. 3 (B), a sharp portion and a dull portion can be intentionally created with one scissors by variously combining the inclination directions of the straight blades.

In general, as shown in FIG. 5, the scissors are provided with a blade 2 as shown in FIG. 5 in order to prevent a gap from being formed between both blade edges at the point where the blades intersect when the blades are closed.
The surface 21 on the back side of 0 is concavely curved so as to reduce the wall thickness (the drawing is exaggerated for easy understanding). Therefore, in the case of the comb blade having a change in the height of the concave blade as described above, the direction in which the blade edge 22 of the concave blade (corresponding to the blade indicated by the phantom line in FIG. 5) moves away from the blade edge of the bar blade by the reduced amount. The edge of the straight blade edge (20 in FIG. 5)
(Corresponding to the dimension T in FIG. 5). In other words, simply lowering the concave blade of the comb blade creates a gap between the blade edge of the low concave blade and the blade edge of the bar blade, and the blade and blade no longer intersect as scissors at that portion, and the blade is cut. The problem disappears.

In the scissors of this embodiment, in order to avoid the above-mentioned inconvenience, the cutting edge of the bar blade and the surface on the back side of the blade have an irregular shape as shown in FIG. Are formed). The protruding cutting edge 23 of the bar blade 12 protrudes by a height corresponding to the dimension T shown in FIG. 5 to engage with the lowered concave blade 15 of the comb blade 11. When the height of the concave blades 15 is different from each other as shown in FIGS.
The height corresponding to T can of course be varied. Thus, the bar blade 1
For the first time, by making the back surface of the blade 2 uneven,
Even with the lowered concave blade, the cutting edge of the bar blade crosses the cutting edge of the bar blade without separating and cuts as scissors.

The straight blade 14 of the comb blade 11 is formed by electric discharge machining or NC machining so as to have a blade angle of about 35 ° as in the case of a conventional cutting scissor bar blade.
It has the same sharpness as cutting scissors.

【The invention's effect】

If the hairdressing scissors of the present invention configured as described above is used, a professional blade is used with scissors in which the straight blades and the concave blades are alternately arranged and the line of the edge of the concave blades is changed. By cutting at high speed, it is possible not only to adjust the hair amount like combing scissors but also to cut the hair style like cutting scissors at the same time, but not to move the scissors delicately as usual However, since the cutting line is rich in unevenness, the line of the tip does not align, and if you move the scissors as before, you can easily add a more natural and rich change of the tip line be able to.
