Description

  The present invention relates to a novel bag. Specifically, the present invention relates to a technique that is suitable for hairdressing and beauty work and that can be applied to a special cutting technique.

  The progress of cutting technology in the hairdressing and beauty industry is remarkable, and special technologies such as slide cutting and effect cutting have become quite popular.

  Recently, in order to further increase the cutting speed, a new method of using a kite, which is a reverse method from the conventional method of holding a kite, has appeared.

  As shown in FIG. 5, the conventional method of holding the heel is to place the heel a with the stationary blade b side up and the moving blade c side down, and in this state, the thumb d is a ring on the moving blade side. Next, the ring finger f is put in the ring g on the stationary blade side and the heel a is gripped. This method of gripping the heel shown in FIG.

  On the other hand, as shown in FIG. 6, the reverse hand inserts the thumb d into the ring e on the moving blade side with the heel a facing down on the stationary blade b side and moving blade c side up, and the middle finger i Is put into the ring g on the stationary blade side and the heel a is gripped.

  In other words, when the heel a is lifted, the cutting edge h faces directly upward (see FIG. 5) and the cutting edge h faces downward (see FIG. 6) in the reverse hand.

  Until recently, most hairdressing and technologists had never thought of using a spear in their hand. Therefore, when cutting the hair at the top of the head, as shown in FIG. 7, the right arm j (in the case of right-handed use. ) And the elbow k were greatly raised and the wrist had to be bent unnaturally.

  Continuing the cutting operation for a long time with the elbow raised as shown in FIG. 7 puts a heavy burden on the shoulder and wrist, causing stiff shoulders and tendonitis.

  Moreover, raising the elbow from the position of the shoulder and continuing the cutting operation also causes a problem that the heel a is likely to become unstable and it becomes difficult to accurately determine the hair design.

  Engineers called top beauticians and top stylists cut over 500 customers a month, so they are very tired and may be physically ill, so they are looking for ways to make accurate cuts without getting tired. It was done.

  Therefore, there is a strong demand for a heel that can be used even when the elbow position is lowered, and a heel as shown in Patent Document 1 has also been developed.

Japanese Utility Model Publication No. 2-109562

  By the way, in the scissors shown in Patent Document 1, since the blade body and the handle body are connected so as to be rotatable and adjustable in the opening and closing direction of the housing, the elbow is not raised so high. Although it has the advantage that the cutting edge can be turned down, it is not as good as the conventional scissors, but it still needs to raise the elbow, and it must be in an unnatural posture compared to normal cutting work There is no change.

  To avoid the need to raise the elbows, the insertion direction of each finger is reversed even when the hand is held with the hand for the traditional hand, so the angle of the ring or finger hook designed for the hand is It was not adapted to the angle of the finger in the case of the reverse hand, and there was a risk of scratching or blistering the finger, or severely damaging the joint.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a bag that can be applied to various cutting techniques and that can be easily operated with a reverse hand.

  In order to solve the above-mentioned problems, the present invention scissors are formed by connecting a first housing having a stationary blade and a second housing having a moving blade so as to be rotatable by a fulcrum shaft bolt. 1 includes a blade body portion in which a stationary blade is formed and the fulcrum shaft bolt is inserted, and a handle body on which a finger is hung. The blade body portion and the handle body of the first housing are The two casings are connected so as to be rotatable in an opening / closing direction of the two casings and in a direction orthogonal to the opening / closing direction.

  Therefore, in the case of the present invention, the angle of the handle on the stationary blade side with respect to the blade body can be freely adjusted.

  The kite of the present invention is a kite in which a first casing having a stationary blade and a second casing having a moving blade are rotatably connected by a fulcrum shaft bolt. And a blade body portion on which the stationary blade is formed and the fulcrum shaft bolt is inserted, and a handle body on which a finger is hung. The blade body portion and the handle body of the first housing are the two housing bodies. It is connected to the opening and closing direction and a direction orthogonal to the opening and closing direction so as to be rotatable.

  Therefore, in the case of the present invention, the angle of the handle on the stationary blade side with respect to the blade body can be freely adjusted. Therefore, it is possible to reduce the burden on the elbow, shoulder, finger, and the like by adjusting the angle of the handle that is the part on which the finger is hung so as to match the position of the finger in the employed cutting technique. In addition, since the unnatural posture is not forced, the hair design can be determined accurately.

  In the invention described in claim 2, the second casing includes a blade body portion in which a moving blade is formed and the fulcrum bolt is inserted, and a moving blade side ring for inserting a finger. The formed handle is integrally connected, and the moving blade side ring includes a plate-shaped belly contact portion that contacts the belly side of the finger, and a substantially semi-annular shape whose open end is substantially closed by the belly contact portion. The belly pad and the anti-separation part are attached to the handle at one end of the anti-separation part and the anti-separation part so as to be adjustable in a direction substantially perpendicular to the opening and closing directions of the two housings. Therefore, the load on the elbow, shoulder, finger, etc. can be reduced by adjusting the angle of the moving blade side ring to match the position of the finger in the cutting technique that employs the angle. In addition, since the unnatural posture is not forced, the hair design can be determined accurately.

  In the invention described in claim 3, the handle portion of the first casing is provided with a stationary blade side ring and a finger hanging portion for inserting a finger, and the stationary blade side ring and the finger hanging portion are provided. Is configured such that the angle with respect to the opening / closing direction of the two casings can be adjusted separately, so that a finger to be inserted into the stationary blade side ring, for example, a ring finger, and a finger to be hung on the finger hanging portion, for example, a little finger It is possible to work in a posture most suitable for the cutting technique to be used by adapting to individual differences in the distance between each other, the angle between each other, and the length of each finger.

  According to a fourth aspect of the present invention, the finger hanging portion is attached to the stationary blade side handle by screwing a fixing bolt inserted through the stationary blade side handle, and the finger hanging portion and the stationary blade Since it is possible to insert a spacer that can be inserted / removed and increased / decreased between the side handle body, the height (position in the opening / closing direction of the housing) of the finger rest portion with the stationary blade side ring Adjustments can be made, and individual differences can be handled more precisely.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  The scissors 1 are formed by a first housing 10 having a stationary blade 11 and a second housing 20 having a moving blade 21 being rotatably coupled by a fulcrum shaft bolt 30. Each of the casings 10 and 20 is composed of blade bodies 12 and 22 each having a stationary blade 11 or a moving blade 21 and handle bodies 13 and 23 that are parts to be hooked with fingers. The ends close to the handle bodies 13 and 23 are coupled by fulcrum shaft bolts 30, and the stationary blades 11 and the moving blades 21 formed respectively are opposed to each other.

  In the following description, when the direction is indicated, for convenience, the direction in which the blade edges of the stationary blade 11 and the moving blade 21 are directed is the front, the opposite side is the rear, and the side on which the stationary blade 11 is positioned is the lower side. explain.

  The blade body 12 and the handle 13 of the first casing 10 on the stationary blade side are connected via a hinge body 14 so as to be rotatable in two directions orthogonal to each other. One end of the hinge body 14 is connected to the rear end portion of the blade body portion 12 by a fixing bolt 15 so as to be rotatable along the opening / closing direction of the two blade body portions 12 and 22. The fixing bolt 15 has a screw shaft portion (not shown) and a head portion 15a provided at one end of the screw shaft portion, and an engaging groove 15b is formed in the head portion 15a. Then, the screw shaft portion of the fixing bolt 15 is screwed into a screw hole (not shown) formed at the rear end of the rear blade body portion 12 inserted from the side through an insertion hole (not shown) formed at the front end of the hinge body 14. In this state, the hinge body 14 is fixed to the blade body portion 12 by strongly screwing the fixing bolt 15 into the screw hole of the blade body portion. Then, by loosening the fixing bolt 15 with respect to the screw hole of the blade body portion 12, the hinge body 14 can be rotated in a direction along the opening / closing direction of the blade body portions 12 and 22. It should be noted that a large force needs to be transmitted to the fixing bolt 15 when the fixing bolt 15 is strongly screwed into the screw hole or when the fixing bolt 15 that is strongly screwed is loosened. Therefore, a large rotational force can be transmitted to the fixing bolt 15 by engaging the tip of the minus driver or the peripheral edge of the coin with the engaging groove 15b of the head 15a and rotating the driver or the coin.

  A distal end portion of the handle 13 is connected to a rear end portion of the hinge body 14 by a fixing bolt 15 so as to be rotatable. The fixing bolt 15 is screwed into a screw hole (not shown) formed in the hinge body 14 from below through an insertion hole (not shown) formed in the tip end portion of the handle body 13 of the fixing bolt 15 and fixed in this state. By firmly screwing the bolt 15 into the screw hole of the hinge body 14, the angular relationship between the handle body 12 and the hinge body 14 in the direction orthogonal to the opening / closing direction of the blade body portions 12 and 22 is fixed. And the angle in the direction orthogonal to the opening-and-closing direction of the blade parts 12 and 22 with respect to the hinge body 14 of the handle 13 can be adjusted by loosening the fixing bolt 15 with respect to the screw hole of the hinge body 14.

  As described above, the handle 13 is connected to the blade body 12 via the hinge body 14 so that the angle of the handle 13 with respect to the blade 12 can be freely adjusted in two directions orthogonal to each other. .

  The handle 13 of the first housing 10 is provided with a ring 16 for inserting a finger, usually a ring finger, and a finger hooking portion 17 for placing a finger, usually a little finger. The ring 16 has a substantially annular shape, and the direction in which the circumference is developed is fixed in the direction along the front-rear direction on the upper surface at a position slightly behind the center in the front-rear direction of the handle 13.

  The finger-hanging portion 17 is substantially L-shaped, and an upright portion 17b projects upward from the rear end of the base portion 17a. A screw shaft portion of a fixing bolt 15 inserted from below through an insertion hole (not shown) formed vertically through the handle 13 behind the ring 16 is formed on a base portion 17a of the finger hook portion 17 (not shown). The angle in the direction perpendicular to the opening / closing direction of the blade body parts 12 and 22 with respect to the handle body 13 of the finger hanging part 17 by screwing the fixing bolt 15 into the screw hole of the finger hanging part 17 in this state. The relationship is fixed. And the angle in the direction orthogonal to the opening-and-closing direction of the blade body parts 12 and 22 with respect to the handle 13 of the finger hook part 17 can be adjusted by loosening the fixing bolt 15 with respect to the screw hole of the finger hook part 17.

  Spacers 18 and 18 can be interposed between the finger-hanging portion 17 and the handle 13 as necessary. The spacer 18 has a thin plate shape, and by inserting the spacer 18, the height of the finger hook portion 17 from the handle 13 can be increased. Although FIG. 1 shows a state in which two spacers 18 are inserted, one or more spacers 18 may be inserted, or the spacers 18 may not be inserted.

  In the second casing 20 on the moving blade side, the blade body portion 22 and the handle body 23 are integrally formed. A ring 24 for inserting a finger, usually a thumb, is provided at the rear end of the handle 23. The ring 24 includes a belly pad portion 25 on which the belly of the finger abuts, and a drop prevention unit 26 that abuts the belly on the belly pad portion 25 to prevent the finger from coming off. The belly pad 25 has a plate shape, for example, a substantially disk shape, and an insertion hole (not shown) is formed in the peripheral edge portion. The slip-out prevention part 26 is formed to have a substantially U-shape, and a screw hole (not shown) is formed in the one end part 26a.

  The belly pad portion 25 and the slip-off preventing portion 26 constituting the ring 24 are attached to the rear end portion of the handle body 23 by the fixing bolt 15. That is, the screw shaft portion of the fixing bolt 15 inserted from above through the insertion hole (not shown) penetrating the rear end portion of the handle body 23 in the vertical direction is inserted through the insertion hole of the abdomen pad portion 25, and further removed. When the fixing bolt 15 is firmly screwed into the screw hole of the removal prevention part 26 in this state, the removal prevention part 26 and the belly pad part 25 are screwed into the screw hole formed in the one end 26a of the prevention part 26. The angular relationship in the direction perpendicular to the opening / closing direction of the blade parts 12 and 22 with respect to the handle 23 is fixed. And the angle in the direction orthogonal to the opening-and-closing direction of the blade body parts 12 and 22 with respect to the handle 23 of the belly pad part 25 and the removal prevention part 26 by loosening the fixing bolt 15 with respect to the screw hole of the removal prevention part 26. Can be adjusted.

  A hit point 27 protrudes upward from the upper surface of the end of the handle body 23 side of the handle body 23 of the second housing 20. A buffer body 27a made of hard rubber, synthetic rubber or the like is fixed to the upper end portion of the hit point 27. When the stationary blade 11 and the moving blade 21 are closed and the cutting operation is performed, the tip of the hit point 27 comes into contact with the lower surface of the blade body portion 12 of the first casing 10 and the stationary blade 11 is further exceeded. And the moving blade 21 are prevented from meshing with each other. As a result, the engagement between the stationary blade 11 and the moving blade 21 becomes too deep, and the operation of opening the stationary blade 11 and the moving blade 21 is prevented from slowing down, so that the cutting speed is not lowered.

  In the heel 1, the ring 24 for inserting the thumb is usually constituted by the belly pad portion 25 and the slip-off preventing portion 26, and both the bell pad portion 25 and the slip-off preventing portion 26 have different angles with respect to the handle 23. It is possible to adjust. As a result, the angle and the shape of the ring 24 are optimized in the case of gripping the heel 1 with the forward hand and the case of gripping the heel 1 with the reverse hand so that, for example, the thumb does not hurt due to the excessive finger posture. In addition, the position of the finger relative to the heel 1 can be stabilized. For example, in the case of a reverse hand, the abdomen pad part 25 and the drop prevention part 26 are adjusted as shown in FIG. 2, and in the case of a forward hand, the abdomen pad part 25 and the drop prevention part 26 are adjusted as shown in FIG. Note that the adjustment states shown in FIGS. 2 and 3 are merely examples, and there are various adjustment positions depending on the characteristics of the user's hand and fingers.

  As described above, for example, the position and state of the thumb with respect to the heel 1 are stabilized. Next, the index finger, the middle finger, the ring finger, and the little finger need to be in a position and state where the heel 1 can be grasped without difficulty. At this time, the most important is the relationship between the ring finger and the little finger. The shape of the hand, the length of the five fingers, and the ratio are not all the same, but they are all different. When using the heel 1, it is ideal that the ring 16 stops on the nail side of the second joint of the ring finger. However, an engineer with a short little finger cannot do this, and when trying to stabilize the little finger, Goes too deep into the ring and hurts the joints.

  In the above-described scissors 1, unlike a normal scissors, the stationary blade side ring 16 and the finger hooking portion 17 are completely separated. Therefore, the optimal position can be determined without the ring finger and the little finger being influenced by each other. For example, in order to align the ring 16 with the nail side of the second joint of the reference ring finger, the fixing bolt 15 that fixes the hinge body 14 and the handle 13 is loosened with respect to the screw hole of the hinge body 14, As shown in FIG. 4, the ring 16 is rotated to the near side or the opposite side of the state shown in FIG. Next, the fixing bolt 15 that fixes the finger hook 17 to the handle 13 is loosened with respect to the screw hole of the finger hook 17 so that the finger hook 17 is positioned at the first joint of the little finger. It is rotated with respect to the handle 13 to obtain an optimum angle. At this time, if the height of the finger rest 17 from the handle 13 is too low for the engineer, no force is applied to the little finger and the cutting edges 11a and 21a of the heel 1 become unstable. It is good to interpose between the finger hook part 17 and the handle 13.

  As described above, the bag of the present invention can adjust the angle and position of the ring and the finger-hanging part according to the characteristics of the user's hand and fingers, is extremely easy to use, and has little fatigue. In particular, it is suitable for performing special techniques such as slide cutting and effect cutting by the reverse method.

  It should be noted that the structure and shape of each part shown in the above-described embodiments are merely examples of the implementation performed in carrying out the present invention, and the technical scope of the present invention is interpreted in a limited manner by these. There should be no things.
