Description

[Detailed description of the invention] This invention relates to scissors, and in particular the brand cut used when trimming the length of hair to a predetermined length according to hair mail, as well as the stroke used when combing hair. It concerns scissors that are also suitable for cutting.

In conventional scissors, the finger hook 11 extends straight in contrast to the movable and static blades.

For this reason, as shown in FIG.
2 had occurred.

This play 12 occurs because the thickness of the finger is not constant from the root to the tip, and the finger rest 12 is adjusted to fit the thick part of the finger.
This is because it determines the size of

Due to this play 12, in conventional scissors, the scissors 13 cannot be firmly fixed to the fingers, and in particular, in the case of swinging IIi scissors such as those used for stroke cutting, the finger hook 11 is not securely fixed to the fingers. As a result, the scissors 13 swayed, making it difficult to stably determine the measurement.

Further, due to the play 12, the finger hook 11 does not hit the entire finger evenly, and the entire scissors 13 is supported by a part of the finger, which places a burden on a part of the finger.

Hair cutting scissors, which are used to cut hair by moving your fingers hundreds of times a day, put a lot of strain on your fingers, which can cause calluses to form on your fingers. was.

On the other hand, in some conventional hair cutting scissors, as shown in FIG. 2, the finger hook 14 is made approximately circular to fit snugly around the fingers.

However, this is used by inserting the thumb into the lower finger rest 14a and the middle finger into the upper finger rest 14bK, with the scissor blade 15 facing the inside of the arm.

There are no scissors that are used by inserting the thumb into the upper finger rest and the middle finger into the lower finger rest, with the blades pointing toward the front of the hand, that fit snugly around the fingers like this.

Furthermore, with conventional scissors, when worn normally, the scissors 13 point slightly outward in the direction of the arm, as shown by the dotted line in FIG.

For this reason, when cutting the hair, it was almost parallel to the line of sight, making it difficult to see.

If you maintain a certain angle to the parent line as shown by the solid line in Figure 3, it will be much easier to see.

Changing the direction of conventional scissors from the dotted line position to the solid line position shown in FIG. 3 puts strain on the wrists and fingers, placing a large burden on the wrists and fingers.

Sara VC Tota, Utility Model Publication No. 50-43026 discloses scissors in which the movable blade finger hook part is formed in an oblique manner so that the thumb can be inserted diagonally from behind the stretched thumb. According to this, the stroke cut, that is, the moving blade finger hook part into which the thumb is inserted is upward.

It works well when cutting by holding the scissors so that the stationary blade finger rest where the middle or ring finger is inserted is directly above it. If you hold the scissors so that it is directly above it when cutting, you will not be able to apply pressure to your middle or ring finger inserted into the static blade finger rest, and the static blade finger rest will not be secured properly, making it difficult to cut accurately. Not only was it impossible to do this, but if you dared to do so, it would put a lot of strain on your wrists.

In this regard, according to the present invention, not only is the movable blade finger rest gently curved in the opposite direction to the side where the thumb is inserted, but the stationary blade finger rest is curved in the same direction as the side where the finger is inserted. Since it is gently curved, the middle finger or ring finger inserted into the stationary blade finger rest will have enough force to apply sufficient force not only for stroke cuts but also for brand cuts, so the static blade finger rest will be securely fixed, allowing stable and accurate cuts. It is possible to do this without putting too much stress on the wrists, and it has the remarkable effect of being able to withstand cutting for a long time.

The purpose of the hair cutting scissors of this invention is to solve the above problems, to reduce fatigue even when the fingers are moved hundreds of times, to be able to be firmly fixed to the fingers, and to be able to easily move and stand still in a position that is easy to see with respect to the line of sight. To provide hair cutting scissors whose blade tips can be directed.

Hereinafter, the structure of the present invention will be explained based on the embodiments shown in FIGS. 4 and 5.

Reference numerals 1 and 2 denote a movable blade piece and a static blade piece of the scissors, respectively, which are joined to each other by a screw 3 at the center of each button.

4 and 5 are a moving blade part and a static blade part, respectively, and the moving blade pieces 1.
The blade portion of the stationary blade piece 2 is shown.

Numerals 6 and 7 are a moving blade finger gripping portion and a static blade finger gripping portion, respectively, for inserting a finger.

Reference numerals 8 and 9 are a moving blade handle portion and a static blade handle portion, respectively, and indicate the portions where the moving blade portion 4 and the moving blade finger hook portion 6, and the static blade portion 5 and the static blade finger hook portion I are connected.

The movable blade finger hook part 6 is gently curved in the opposite direction to the side where the thumb is inserted, and the stationary blade finger hook part T is gently curved in the same direction as the side where the middle finger or ring finger is inserted. There is.

Therefore, both finger hooks 6, 7I/i are bent in opposite directions to form the configuration shown in FIGS. 4 and 5.

Next, the operation of the present invention will be explained.

To use the scissors of the present invention, insert your thumb into the movable blade finger hook 6 and your middle finger or ring finger into the static blade finger hook 7ttc and move.

At this time, the fingers are inserted into both the interlocking parts 6 and 7 from an almost perpendicular direction, and the nine fingers gradually become thicker from the tip to the base, so the finger rests at a point corresponding to the size of the finger rests 6 and 7. 6
．． 7 fits perfectly on my finger.

Therefore, the scissors are stably locked without wobbling, and there is no play between the fingers and the finger hooks 6, 7, so there is no need to place an undue burden on part of the fingers. Suitable for lightweight cutting.

By bending your middle finger, the direction of the scissors becomes almost parallel to your arm, allowing you to maintain a constant angle to your line of sight.

At this time, as shown by the one-dot chain line in FIG.
7 are bent in opposite directions, so you can grip the scissors in a natural state without putting strain on your wrists or fingers.

As mentioned above, the present invention not only curves the movable blade finger rest gently in the opposite direction to the side where the thumb is inserted, but also curves the stationary blade finger rest in the same direction as the side where the middle or ring finger is inserted. Since it is gently curved, it is suitable not only for stroke cuts but also for brand cuts, and it is less tiring even when moving it for a long time, and it can be firmly fixed on the finger.
Moreover, it has the excellent effect of allowing the user to easily direct the scissors to a position that is easy to see with respect to the line of sight.
