Description

  The present invention relates to hairdressing scissors, and more particularly to a barber scissors for reverse hand.

  In the recent barber and beauty industry, various hairstyles have been created according to the shift of fashion, and the personal style is also diverse, so the hairstyles required are wide. In response to this, the pursuit of improving haircut technology is also active. In addition, the hairstyle completion process is shown in a show, and the cutting technique itself is made artistic. For example, novel cutting methods such as changing the conventional method of scissors scissors, opening and closing the scissors blade quickly to increase the cutting speed, or changing the cutting angle of the blade with respect to the hair are also disclosed.

  The hairdressing scissors shown in FIG. 16 is a general hairdressing scissors 100 for hairdressing, and is a tool for cutting hair by a pair of blades composed of a moving blade 101 and a stationary blade 102. Handles 101A and 102A are connected to the respective blades 101 and 102, and finger rings 101a and 102a into which fingers can be inserted are formed at the tip end region of the handle. The hairdressing scissors 100 are combined with screws 103 so that the pair of blades 101 and 102 can be freely opened and closed. Then, when the finger rings 101a and 102a located on one end side of the barber / beauty scissors 100 with the blade opened in an X shape are brought close to each other, the screw 103 serves as a fulcrum and a pair of two As the blades 101 and 102 are bitten, the hair can be cut.

  16 is a right-handed hairdressing and scissors scissors, and is represented in a posture with the moving blade 101 in front of the figure and the stationary blade 102 in the back. In the conventional normal way of holding, the right thumb is inserted into the finger ring 101a on the moving blade 101 side from the stationary blade 102 side (from the back to the front side in FIG. 16), and the ring finger is inserted into the finger ring 102a on the stationary blade 102 side. Put the hairdressing scissors 100 in the same direction as the thumb. This method of gripping scissors is said to be good.

  On the other hand, FIG. 17 shows how to hold scissors called reverse hand. The hairdressing and scissors scissors used in FIG. 17 is the hairdressing and scissors scissors 100 similar to that in FIG. 16, and the hairdressing and scissors scissors in FIG. 16 is rotated 180 degrees, that is, in a posture in which the blade edge faces downward. When a right-handed person holds the right-handed hairdressing scissors 100 with his / her reverse hand, the direction in which the finger is inserted into the finger ring is the same as that of the forward grip, but the finger ring into which the finger is inserted is reversed. Become. That is, while inserting the thumb of the right hand into the finger ring 102a on the stationary blade 102 side, from the stationary blade 102 side to the moving blade 101 side (from the back to the near side in FIG. 17), the ring finger is inserted into the finger ring 101a on the moving blade 101 side, Insert the hairdressing scissors 100 from the back to the front side.

  In this way, by grasping one scissors forward and backward, various cutting methods can be performed by freely changing the angle of the blade edge with respect to the head. However, there is a possibility that wrists, arms, shoulders, etc. may be damaged when the operator holds the scissors originally designed for hand in reverse. This is because the finger inserted into the finger ring is different between the forward and reverse hands, so the scissors that were originally considered for use with the forward hand are not adapted to the finger mounting angle when the finger ring is in the opposite hand position or angle. It is due to that. As a result, it became unstable and caused injury and fatigue.

  In order to solve this problem, scissors have been developed that can adjust the angle of the scissor handle and the position of the finger ring depending on whether the hand is used or not (for example, Patent Document 1). The barber / scissors 200 shown in FIG. 18 includes a first scissors body 210 having a stationary blade 211 and a second scissors body 220 having a moving blade 221 pivotally supported by a fulcrum shaft bolt 230. Yes. Further, the first scissors 210 has a handle 213 provided with a finger ring 216 for fixing the ring finger. The handle body 213 is connected via a stationary blade 211 and a hinge body 214. With this structure, the handle body 213 can freely rotate in two orthogonal directions to adjust the angle. Specifically, fixing bolts 215 a and 215 b are attached to both ends of the hinge body 214. First, the handle 213 can be rotated in the opening / closing direction of the stationary blade 211 and the moving blade 221 by adjusting a fixing bolt 215a attached to one end side of the hinge body 214, that is, the stationary blade 211 side. Further, by adjusting the fixing bolt 215b attached to the other end side of the hinge body 214, that is, the handle body 213 side, the handle body 213 rotates in a direction orthogonal to the opening / closing direction of the stationary blade 211 and the moving blade 221. it can.

In the second scissors 220, the moving blade 221 and the handle 223 are integrally formed, and a finger ring 224 into which a thumb can be inserted is provided at one end of the handle 223. The finger ring 224 is connected to the one end side of the handle 223 opposite to the blade edge by a fixing bolt 215c, and the angle of the finger ring 224 can be freely adjusted by adjusting the fixing bolt 215c. . With this structure, by adjusting the fixing bolts 215a, 215b, and 215c, it is possible to use hairdressing and scissors that correspond to different finger insertion angles depending on the forward and reverse hands.

  However, the adjustment function of the hairdressing scissors 200 in FIG. 18 only helps the posture when the scissors are held in a stationary state, and is difficult to use in use. This is because in an actual cutting operation, it is necessary to twist the scissors in order to change the contact angle of the blades with the object to be cut while grasping the scissors and opening and closing the blades of the scissors. . By this series of operations, the relative position between the scissors and the hand changes in a complicated manner, so that the fatigue cannot be wiped off only by adjusting the stationary state alone.

  For example, when using the hairdressing and scissors scissors in FIG. 18 to cut a predetermined region of the head, or apply a scissors blade at various angles to a bunch of hair drawn from the head Then, it is necessary to variously change the angle at which the blade contacts the surface of the scissors blade and the object, and as a result, the wrist needs to be twisted excessively. In particular, due to the structure of the hand, it is difficult to twist the wrist outward, and there is a risk of inducing tendonitis.

  The present invention has been made to solve the conventional problems. A main object of the present invention is to provide a hairdressing scissors that can easily perform a series of operations for opening and closing the blade and changing the direction of the blade while holding the scissors in the opposite hand.

  In the fifth hairdressing scissors of the present invention, a single or a plurality of finger contact portions 6 capable of contacting at least a part of the finger are formed between the second finger ring 21 and the second blade 23. It is characterized by that.

  Further, the sixth hairdressing scissors of the present invention is connected to the first blade 13 and the first finger ring 11 to fix the relative position between the first blade 13 and the first finger ring 11. And a second handle 22 that is connected to the second blade 23 and the second finger ring 21 and can fix the relative position of the second blade 23 and the second finger ring 21. A part of the second handle 22 is formed so as to be able to come into contact with the palm or finger pad.

  Further, according to the seventh hairdressing scissors of the present invention, the first handle 12 or the first finger ring 11 is provided with a region 7 protruding toward the second handle 22 side, and the cutting edge is opened. When the first blade 13 or the second blade 23 rotates in the direction of approaching each other, the protruding region 7 is the second finger ring 21 or the second finger ring 21 at a position where the first blade 13 and the second blade 23 substantially overlap each other. The second handle 22 is in contact with the first handle 13 and the second blade 23 is prevented from rotating.

  Further, the eighth hairdressing scissors of the present invention uses the fulcrum part 3 in the state where the first blade 13 and the second blade 23 are closed as the reference point G, and the cutting edge direction from the reference point G as the z-axis, Further, in the xy plan view when a straight line that passes through the reference point G and is orthogonal to the rotation surface H2 is the x-axis, and a straight line that passes through the reference point G and is parallel to the rotation surface H2 and orthogonal to the x-axis is the y-axis.

It is not arranged and has a structure where both intersect. That is, the relative position between the first finger ring and the scissors blade is three-dimensionally configured. With this three-dimensional configuration, the trajectory of the finger ring when the blade is stationary is similar to the posture of the hand holding the barber / scissors and the movement posture of the hand when opening and closing the blade. As a result, fatigue when using hairdressing scissors can be minimized. In addition, the hairdressing and scissors scissors of the present invention are rotated in the direction of the blade surface in the state where the scissors are gripped to the little finger side with the blade edge direction as an axis. Thereby, when using hairdressing scissors, it is possible to reduce the twist to the side where the burden is large due to the structure of the wrist and to widen the direction of the blade surface.

It can also be realized by sharing. In addition, the contents described in some examples and embodiments may be used in other examples and embodiments.

  FIG. 1 is a perspective view of a hairdressing scissors in a closed blade state, and FIG. 2 is a hairdressing scissors in a closed blade state in a hairdressing scissors scissors according to Example 1 (hereinafter, sometimes simply referred to as “scissors”). 3 is a front view, FIG. 4 is a rear view, FIG. 5 is a right side view, FIG. 6 is a left side view, FIG. 7 is a plan view, and FIG. Moreover, the common code | symbol in these figures has shown the member same or the same quality, and abbreviate | omits detailed description suitably.

  The hairdressing and scissor scissors 1 in FIGS. 1 to 8 include a first blade 13 and a second blade 23 (hereinafter also simply referred to as “blade”) that can be rubbed together, and the first blade. 13 and the fulcrum part 3 which pivotally supports the 2nd blade 23 rotatably. Further, the hairdressing scissors 1 has a first finger ring 11 and a second finger ring 21 (hereinafter simply referred to as “finger ring”) on which fingers can be placed. , 21 are connected to the individual blades 13, 23 with handles 12, 22. When the user puts his / her finger on the finger rings 11 and 21 and moves them, the blades 13 and 23 rotate around the fulcrum portion 3, that is, the opening and closing of the blades 13 and 23 can be adjusted with the finger rings 11 and 21. Further, in the present specification, the patterns 12 and 22 are sometimes distinguished from the first pattern 12 and the second pattern 22 for convenience by the connected finger rings. Further, the “finger ring shape surface” refers to a surface substantially including at least a part of a contour constituting the ring of the finger ring.

(Blade overlap)
In the hairdressing and scissors scissors 1 according to the embodiment, the first finger ring 11 is for the thumb, that is, the first finger ring 11 is formed so that the thumb can be hung. Further, the hairdressing and scissors scissors 1 in FIG. 1 is a state in which the first blade 13 and the second blade 23 are rubbed together, and the second blade 23 is placed on the back side of the first blade 13, that is, on the back side in FIG. The blades 23 are superposed. This state is defined as a closed blade state of the hairdressing scissors 1. When the hairdressing scissors 1 in the closed state is viewed from the front side (the left front side in FIG. 1), the first blade 13 is rotated clockwise and / or the second blade 23 is rotated counterclockwise. FIG. 2 shows a state in which the blade edges of both the blades 13 and 23 are opened, and this state is referred to as an open state of the hairdressing scissors 1.

  Also, as shown in FIGS. 1 to 8, the handles 12 and 22 are appropriately bent and formed in a desired direction, and the relative positions of the blades 13 and 23 and the finger rings 11 and 21 are fixed to a predetermined posture. In the example shown in FIG. 2, the first finger ring 11 is placed on the far side of the drawing with respect to the rotation surface H2 of the blades 13 and 23 due to the bending of the first handle 12, and the second finger ring 21 is on the near side of the drawing with respect to the rotation surface H2. Located on each side. That is, as shown in FIGS. 1 and 2 and 5 to 6, the first handle 12 connecting the first blade 13 and the first finger ring 11 straddles the second blade 23 or the second handle 22. Is bent. In other words, as shown in FIG. 1 and FIGS. 5 to 6, the second blade 23 is formed between the first finger ring 11 and the first blade 13. In the example of FIG. 2, due to the bending of the first handle 12, the first finger ring 11 is located on the far side of the drawing with respect to the rotation surface H <b> 2 of the blades 13 and 23, and the second finger ring 21 is illustrated with respect to the rotation surface H <b> 2. It is located on the near side. As a result, as shown in FIG. 2, a line (center connection of the finger rings) L <b> 1 connecting the approximate centers of the shape surfaces of the finger rings 11 and 21 is configured not to be parallel to the rotation surface H <b> 2 of the blades 13 and 23. Is done. Therefore, in the hairdressing and scissor scissors 1, when the posture in which both the blade tips in FIG. 1 substantially coincide with the vertical direction is a basic posture, the blade rotation surface H2 configured by opening and closing the blade as shown in FIG. It intersects with a vertical plane H1 containing the central connection line L1 (hereinafter sometimes referred to as “finger ring plane”).

(ring)
Moreover, the hairdressing scissors 1 shown in FIGS. 1-8 is a plane in which the rotation surface H2 of the blades 13 and 23, the shape surface of the first finger ring 11, and the shape surface of the second finger ring 21 are separate from each other. It is formed above and is not located on the same plane. In addition, as shown in FIG. 1, the center axes 15 and 25 of the respective shape surfaces of the first finger ring 11 and the second finger ring are positioned in a torsional positional relationship so that the hairdressing scissors 1 is three-dimensionally. It is composed. Further, in the example of FIG. 1, the central axis 25 of the second finger ring 21 is substantially parallel to the axial direction of the second blade 23.

  Moreover, the finger rings 11 and 21 of Example 1 are cyclic | annular as shown in FIGS. 1-8, The circumference | surroundings of a finger and the inner surface of a finger ring are made contactable by inserting a finger into this cyclic | annular hollow. As a result, the degree of close contact between the finger rings 11 and 21 and the finger is increased, and the hairdressing scissors 1 are firmly fixed with the finger rings 11 and 21, and the opening / closing state of the blade and the direction of the blade edge can be freely controlled. However, the shape of the finger rings 11 and 21 is not limited to this, and can be various shapes as long as at least a part of the periphery of the finger can be contacted, for example, a part of the ring of the finger ring opened, An annular diameter can be selected as appropriate.

  In the hairdressing and scissors scissors 1 of the first embodiment, the relative positions of the finger rings 11 and 21 and the blades 13 and 23 are important. As will be described in detail later, the two are fixed with the handles 12 and 22 so that both are in a predetermined positional relationship. The This is because the position of the finger ring greatly affects the ease of work and fatigue of the user. In the relationship between the scissors and the hand, if the finger is put on the finger ring and the scissors are gripped, the relative positions of the hand and the scissors are determined. In other words, the scissor grip style largely depends on the position of the finger ring. In addition, even when the scissors are opened and closed, the movement of the finger is defined by the movement of the finger ring. In other words, in a device with a fixed shape like scissors, finger movement is forced to the mechanical structure of the scissors, and if the hand movement and the scissor movement are significantly different, it can cause fatigue. . Therefore, it is preferable to arrange the finger ring in the closed blade state so as to match the natural finger movement. Moreover, it is preferable that the locus of the displacement of the finger ring of the scissors substantially coincides with the movement of the finger when opening and closing the blade. Thereby, since the mechanical movement of the finger ring and the movement by the structure of the hand are similar, the fatigue of the user is reduced, and the work efficiency is increased.

(First finger ring)
Below, the formation position of a finger ring is demonstrated for every finger ring. First, the first finger ring 11 according to the first embodiment is connected to one end of the first handle 12, and the shape surface of the finger ring 11 is raised above the axial direction of the handle 12, as shown in FIG. Configured to posture. Further, it is preferable to arrange the finger ring 11 in a posture in which the shape surface of the finger ring 11 is twisted in the rotation direction of the first blade 13. A specific shape surface of the finger ring 11 will be described with reference to FIG. FIG. 9 is an explanatory diagram for explaining the orientation of the shape surface of the first finger ring 11, and is a member of the barber scissors 1 in order to indicate the relative position between the first blade 13 and the first finger ring 11. Shows a state in which is placed in a simulated manner in space coordinates. In FIG. 9, the origin C of the spatial coordinates is a connection position between the first finger ring 11 and the first handle 12, and the z-axis corresponds to the axial direction of the blade. The shape surface of the first finger ring 11 is three-dimensionally connected to the first blade 13, but the shape surface of the finger ring 11 is a basic plane F1 containing the axial direction D1 of the handle 12 and the x axis. From the above, it is easy to understand if it is considered to be a combination of two-stage orientation changes. Here, the orientation changes at each stage will be described individually. However, when the first finger ring 11 is actually formed, the following two steps may be performed in random order, or the first finger ring 11 may be directly formed to satisfy the final relative position.

  First, as a first step, as shown in FIG. 9A, a surface obtained by rotating the basic surface F1 in the direction closer to the positive region of the zx plane with the x axis as an axis is defined as a second surface F2. The rotation amount A1 from the basic surface F1 to the second surface F2 is preferably 0 to 90 °, and more preferably 5 to 80 °. A second stage angle change is added to the second surface F2. That is, as shown in FIG. 9B, a surface obtained by rotating the second surface F2 counterclockwise when viewed from the positive direction of the axis D2, with the diameter direction D2 of the first finger ring 11 passing through the origin C as an axis. Is the third surface F3. The rotation amount A2 from the second surface F2 to the third surface F3 is preferably 0 to 120 °, and more preferably 5 to 80 °. In the first finger ring 11 of the first embodiment, the shape surface of the finger ring is formed at the position and posture contained in the third surface F3 with the origin C of the finger ring as a reference point, and the first blade 13 is fixed. To do. Further, the length of the handle 12 is preferably 1 to 6 cm, whereby the blade 13 and the finger ring 11 are suitably separated from each other so that the scissors and fingers can move smoothly.

(Second finger ring)
On the other hand, the relative position of the second finger ring 21 with respect to the second blade 23 will be described with reference to FIG. FIG. 10 is an explanatory view showing a state in which the members of the hairdressing scissors 1 viewed from the back side are arranged in a simulated manner in the space coordinates, and the connection position of the second finger ring 21 and the second handle 22 is defined as a space. The origin of coordinates is C ′, and the z-axis corresponds to the axial direction of the second blade 23. The shape surface of the second finger ring 21 is inclined downward with respect to the axial direction d1 of the second handle 22 with the origin C ′ as a fulcrum, and is further configured to undergo one or more rotational movements. . In the embodiment, it is assumed that the relative position between the shape surface of the finger ring 21 and the blade 23 is achieved by combining three orientation changes from the reference surface as in the first finger ring 11, and the orientation change at each step is as follows. explain. However, when configuring the relative position of the finger ring and the blade, the above two steps may be achieved in any order, or the final relative position may be determined and then fixed with a handle, etc. The method is not limited.

  First, as shown in FIG. 10, an xy plane orthogonal to the blade 23 is defined as a basic surface f1, and the basic surface f1 is rotated clockwise when viewed from the positive direction of the x axis with the x axis as an axis. Let it be the second surface f2. The rotation amount a1 from the basic surface f1 to the second surface f2 is preferably 0 to 90 °, and more preferably 5 to 80 °. In addition to this rotation, as shown in FIG. 11, when the finger ring 21 is viewed on the second surface f2 from the positive direction of the z axis in the clockwise direction (the arrow direction of the thick line shown in FIG. 11), You may rotate in the range of 120 degrees, More preferably, in the range of 5 degrees-80 degrees. Subsequently, a second stage angle change is applied to the second surface f2. That is, as shown in FIG. 12, a surface obtained by rotating the second surface f2 in the clockwise direction about the diameter direction d2 of the second finger ring 21 passing through the origin C ′ is defined as a third surface f3. The rotation amount a2 from the second surface f2 to the third surface f3 is preferably 0 to 90 °, and more preferably 5 to 80 °. The second finger ring 21 of the first embodiment is fixed to the second blade 23 by forming the finger ring shape surface at the position and orientation contained in the third surface f3 with the origin C ′ of the finger ring as a reference point. To do.

  Moreover, as shown in FIG. 6, the 2nd handle | steering_wheel 22 which concerns on Example 1 inclines the axial direction d1 to the front direction (right direction of FIG. 6). Specifically, the axial direction d1 of the second handle 22 has an inclination angle a3 in the range of 0 to 90 °, more preferably in the range of 5 ° to 80 ° with the z axis corresponding to the axial direction of the second blade 23. Constitute. An inclination within this range is preferable because the tip region of the finger inserted into the second finger ring can easily come into contact with a finger contact portion 6 described later, that is, scissor fixation is further stabilized. However, without providing an inclination, that is, the second handle 22 is extended from the second blade 23 in the axial direction of the blade, that is, the axial direction d1 of the second handle 22 is set as the axis of the second blade 23. It may be substantially the same. This facilitates design and manufacture.

  Moreover, the shaping | molding method will not be specifically limited if the pattern 12 and 22 fix the relative position of a blade and a finger ring to a predetermined position as mentioned above. For example, a part of the handle of the integrally formed scissors is cut with a grinder or the like, and the cut is pressed to bend the handle in a predetermined direction, or the blade and the finger ring are placed at a predetermined position. After the positioning, the relative positions of the blade and the finger ring may be fixed by connecting the two with separate handle portions. Furthermore, the material of the patterns 12 and 22 is not particularly limited as long as the finger ring has a relative position with respect to the blade surface and has a strength that does not deform even when the blade is opened and closed. For example, in addition to the same material as the blade, a thermoplastic resin or a metal material different from the blade can be used. Moreover, a member can also be made into a rotation type by connecting each member with rotation shafts, such as a screw and a pin. For example, the connecting part between the finger rings 11 and 21 and the handles 12 and 22, the connecting part between the handles 12 and 22 and the blades 13 and 23, etc. are connected by a rotating shaft, or the handles 12 and 22 are divided into a plurality of parts By connecting the small members with the rotation shaft, the connection angle between the members can be freely configured, and the scissors can be configured in three dimensions, and the angle can be adjusted according to the size of the user's hand and the length of the finger.

(Finger and finger ring movement)
The hairdressing and scissors scissors 1 of Example 1 have the relative position of the blade and the finger ring within the above range, so that the axial direction of the finger in a state where the user grips the scissors and the direction of the central axis of the finger ring substantially coincide. Furthermore, the locus of the central axis 15 of the first finger ring can be approximated to the locus of the thumb axis in the blade opening / closing operation. The movement of the hand and the hairdressing scissors during use will be described below with reference to FIG. FIGS. 13A and 13B are explanatory views showing the usage state of the hairdressing scissors, where FIG. 13A shows the gripping state in the closed blade state, and FIG. 13B shows the gripping state in the open blade state. However, in the explanatory diagram of FIG. 13A, in order to clarify the support position of the thumb, a state in which the thumb is exposed by intentionally raising the index finger and the middle finger is shown.

(Use state)
When the operator uses the hairdressing scissors 1, as shown in FIG. 13, the thumb as the first finger B1 is inserted into the hollow of the first finger ring 11 from the back side of FIG. A ring finger which is the second finger B2 is inserted into 21 from above. Then, by moving the first finger B1 outward, the first finger ring 11 is displaced outward as shown in FIG. 13B, and the scissors blades 13 and 23 are opened in conjunction with this movement. In the hairdressing scissors 1, the object caught by the second blade 23 when the blades 13, 23 are opened is moved closer to the second blade 23 side by the first blade 13 and finally shown in FIG. 13 (a). Thus, the object can be cut by sliding the first blade 13 and the second blade 23 together. Due to such a difference in roles, the first blade is also referred to as a moving blade 13 and the second blade 23 is also referred to as a stationary blade. However, the static blade is named based on the difference between the roles of the two blades and is not always stationary.

  On the other hand, the thumb moves very well compared to other fingers due to the structure of the joints of the hand. When the thumb is bent, the thumb faces the other four fingers. Therefore, it is preferable from the finger structure that the finger on the first finger ring is the thumb and the rotation of the hairdressing scissors 1 on the moving blade 13 side is adjusted with the thumb.

  In addition, as described above, the central axes 15 and 25 (see FIG. 1) of the finger rings 11 and 21 in the hairdressing scissors 1 are fingers inserted into the finger rings 11 and 21 in the fingers of the hand holding the scissors. This corresponds to the axial direction near the base of the. As a result, when the fingers B1 and B2 are inserted into the finger rings 11 and 21 and the barber / scissors 1 are gripped with the other hand, each finger ring naturally fits the finger of the hand in the posture that made the fist. In the gripping state of the hairdressing scissors 1, as shown in FIG. 13A, the tips of the blades 13 and 23 provided below the finger rings 11 and 21 are in the vertical direction, that is, the hairdressing scissors 1 is under the fist. The posture is hung. That is, since the weight of scissors can be supported from above the hairdressing scissors 1, the burden on the wrist can be easily reduced as compared with the conventional case of supporting the hairdressing scissors 1 from the lateral direction. As a result, the blades 13 and 23 of the hairdressing scissors 1 can be freely moved, so that agile blade cutting can be performed and hands are not tired.

  Furthermore, the locus of the normal line in the finger ring when the blade is opened and closed can be substantially equal to the locus of the thumb shaft bone when the thumb is opened and closed. Specifically, in the displacement of the finger ring 11 from the closed blade state to the open blade state, the direction of the central axis 15 of the finger ring 11 can be made substantially the same as the direction of the thumb axis P shown in FIGS. . That is, since the mechanical movement of the scissors and the movement of the finger substantially coincide, the burden on the finger due to the scissors opening / closing operation can be reduced and the operation can be performed easily.

(Finger rest)
Moreover, the 2nd handle | steering_wheel 22 which concerns on Example 1 is provided with the finger | toe contact part 6 between the 2nd blade 23 and the 2nd finger ring 21, as shown in FIG.1, FIG.6, FIG.13. The scissors support can be further stabilized by inserting the second finger B <b> 2 into the finger ring 21 and further abutting or stopping the finger pad against the finger rest 6. Therefore, the shape and material of the finger pad 6 are not particularly limited as long as at least the finger pads can come into contact. In the example of FIG. 13, the material is the same as that of the handle and is formed in a linear shape, and is connected substantially orthogonal to the axial direction of the second handle 22. In addition, the surface of the finger pad 6 can be textured to increase the frictional force, or can be covered with an elastic material such as rubber having a high friction coefficient.

  In addition, the degree of adhesion can be increased in accordance with the shape of the outer surface of the finger contact portion 6 where the finger is brought into contact with the shape of the finger belly. Furthermore, as shown in FIG. 5 and FIG. 6, by providing the step 22 and the step by projecting the finger pad 6 forward, it is possible to hang a finger on the lower side of the step, thereby grasping more scissors. It can be done easily. In particular, by placing a finger on the finger rest 6, the finger rest 6 can be supported so as to be lifted upward from the lower side of the finger rest 6, that is, can receive the gravity of the scissors. It is possible to prevent the hairdressing scissors 1 from falling off the finger ring and falling downward. In particular, the scissors for the reverse hand are held downward, that is, when the index finger or the like is pointing downward, there is a problem that the scissors are easily pulled down due to the weight of the scissors. In view of such a structure, in the present embodiment, as described above, the shape of the finger pad is devised to realize scissors that are difficult to slip off and are easy to grip.

  Furthermore, the burden which supports scissors can also be disperse | distributed by providing the finger | toe contact part 6 multiple and making a finger | toe applicable to each finger contact part 6 contact or hook. Alternatively, a plurality of fingers may be brought into contact with one finger pad. For example, in Example 1, as shown to Fig.13 (a), the length in the longitudinal direction of the finger | toe contact part 6 is extended | stretched to such an extent that it contains the area | region of the several contact | abutted several finger | toe. In use, a thumb is inserted from the back side into the hollow of the first finger ring 11 on the moving blade 13 side. At the same time, the ring finger is inserted into the second finger ring 21 from above to the vicinity of the first indirect, and the side surface region inside the ring finger is brought into contact with the finger contact portion 6. Further, the first indirect of the middle finger is bent to bring the middle finger of the middle finger into contact with the lower surface side of the finger pad 6. Thereby, it can be set as the attitude which pushes up finger touching part 6 from the lower surface side with the belly of the middle finger. As a result, it is preferable that the stationary blade side is securely fixed and a quick turning motion of the moving blade is realized. In addition, it is preferable that the cutting edge can be oriented upward by hooking a finger on the finger rest 6 and lifting the scissors from the lower side, that is, the direction of the cutting edge can be controlled over a wide range. As described above, the finger contact portion 6 is preferably configured so that a plurality of fingers can come into contact with each other, but on the other hand, there is one finger contact portion 6 corresponding to any one finger such as for the middle finger or for the ring finger. The provided structure may be sufficient.

  Further, the hairdressing and scissors scissors of Example 1 may be provided with a stopper capable of determining the closing position of the blade. The stopper means that when the blades 13 and 23 in the open state are rotated in a direction approaching each other, the blades are prevented from rotating at a position where both the blades 13 and 23 substantially overlap each other, and the blades are positioned further than the blade stacking position. Plays the role of deterring progress. In the example of FIGS. 1 to 13, a region 7 protruding from a part of the first finger ring 11 toward the second finger ring 21 is used as a stopper, and the stopper 7 is in the second blade state when the blades 13 and 23 are closed. It is comprised so that the front-end | tip part of the handle | steering_wheel 22 may contact | abut. In other words, when the stopper 7 comes into contact with the second handle 22, the displacement movement of the finger ring 11 is stopped and the blade is closed. The shape and position of the stopper 7 and the contacted portion are not particularly limited, and various materials can be used for the stopper 7. However, an elastic body such as rubber or resin capable of absorbing noise and stress at the time of contact is preferable at the stopper or the portion where the stopper is brought into contact.

  Further, the second handle 22 may be provided with a grip assisting portion 4 that can come into contact with the palm. In the example of FIG. 1, the grip assisting portion 4 is curved upward from the tip region of the second handle 22, that is, from the connection position with the second finger ring 22 to the tip portion. When the hairdressing scissors 1 is gripped, the curved portion comes into contact with the vicinity of the finger base or the finger pad of the palm. As a result, the finger resting portion 6 and the bending portion can be held between the middle finger and the vicinity of the palm, so that the stationary blade side can be gripped more stably. Furthermore, with the palm portion in contact with the curved portion as a fulcrum, the hairdressing scissors 1 are pulled up from below by placing the middle finger or other finger on the finger rest portion 6 so that the cutting edge is easily raised upward. be able to. That is, the direction of the cutting edge can be easily changed, which is preferable. However, the shape of the grip assisting portion 4 is not limited to the curved shape in the distal end region of the second handle 22. For example, in order to increase the contact area with the palm, various shapes such as a planar shape may be used, or separate members may be connected. Moreover, although the formation location of the holding | maintenance auxiliary | assistant part 4 is not limited to the 2nd handle 22, it is preferable to form in the member connected with the stationary blade side. As a result, the stationary blade side is securely gripped, and the opening / closing movement of the blade can be easily controlled. In the second handle 22 according to the first embodiment, a part of the handle is molded so as to be in contact with the palm, thereby forming the grip assisting portion 4, and the tip of the handle 22 is covered with an elastic cap so as to be a stopper. 7 is also used as a contact portion.

(Blade stacking order)
Further, in the hairdressing and scissors scissors 1 of Example 1, the way in which the blades overlap is different from that of conventional scissors. That is, when the operator uses the scissors with his / her reverse hand, as shown in FIGS. 17 and 18, in the conventional scissors, the moving blades 102 and 221 are stacked on the upper side of the stationary blades 101 and 211, that is, on the side away from the operator. On the other hand, in the hairdressing scissors 1 of Example 1, as shown in FIGS. 1 to 13, the stacking order of the blades is opposite, that is, the stationary blade 23 is on the upper side of the moving blade 13, and the moving blade 13. Is located remotely from the operator. This is a conventional scissors for hand and comparable to the way the left-handed scissors blades overlap. With this structure, when the blades 13 and 23 are rubbed together, the operator only has to move the first finger ring 11 to the remote side and does not need to pull it forward. This is due to the lever principle. That is, if the fulcrum part 3 is used as a fulcrum and the handle 12 on the thumb side, which is the power point side, is pressed to the remote side, the moving blade 13 which is the action point side is brought closer to the inner side, that is, the stationary blade 23 side, Both blades are better aligned.

  With conventional scissors, it is necessary to raise the finger ring toward the back of the hand, that is, the operator side while keeping the finger ring close together, and to bring the finger ring closer to the index finger side. Because it is not, unnatural power enters and it becomes a cause of overwork. Or if it is going to tighten | tighten the screw | thread of the fulcrum part 3 and implement | achieve the favorable friction of a blade, the frictional force between blades will become large and the force required for opening and closing of a blade will increase. As a result, the user tends to get tired. On the other hand, in the case of the blade stacking order by the hairdressing scissors of Example 1, as described above, the insertion direction of the thumb coincides with the pressing direction on the power point side for realizing satisfactory blade alignment. Therefore, the finger ring is pressed in the insertion direction without being particularly conscious, that is, good blade alignment can be realized by the natural movement of the thumb. This significantly reduces the burden on the hand as compared with the operation of pulling up the finger ring toward the front side, and can control the speed of the opening and closing movement of the blade with high accuracy. In addition, since the screw of the fulcrum part 3 can be loosened, the blade can be opened and closed with a light force, and fatigue can be further reduced.

(Direction of blade surface)
Further, the hairdressing scissors 1 of the first embodiment is configured such that when the operator holds the hairdressing scissors 1, the blade surface of the hairdressing scissors 1 faces the second finger ring 21 side, that is, the operator's little finger side. Yes. The twist of the blade surface will be described with reference to FIG. As shown in FIG. 2, the center connection line L <b> 1 of the finger rings 11 and 21 intersects the rotation surface H <b> 2 of the blades 13 and 23. In other words, the finger ring surface H1 including the center connection line L1 of the finger rings 11 and 21 is not parallel to the rotation surface H2 including the blade surfaces of the first and second blades, but is configured to intersect. That is, the finger ring surface H1 and the blade surface H2 intersect with each other at a rotation angle A3 of greater than 0 ° and less than or equal to 90 °, more preferably 5 ° to 80 ° with the vertical direction as an axis.

  On the other hand, the relationship between the hand and the blade surface when the operator holds the hairdressing scissors will be described with reference to FIG. FIG. 14 is an explanatory view showing the relationship between the hand and the cutting direction by the scissors in the gripping state, and is a simplified view of the operator I who performs the haircut and the haircut person Y from above. First, in the gripping posture of the operator I's scissors, the posture in which the worker has a wrist substantially straight and the finger ring surface H1 is substantially parallel to itself or the object is set as a reference gripping posture. . In other words, in the standard gripping posture, the operator I or the hair subject Y is substantially parallel to the finger ring surface H1, but the blade surface H2 is oriented toward the operator's little finger. That is, when the operator I holds the hairdressing scissors 1 and the operator I views the hairdressing scissors 1 from above, the blade surface H2 is rotated by a rotation angle of A3 in the clockwise direction with respect to the vertical axis. It is configured in a rotated state, that is, a posture twisted in an obliquely downward right direction shown in FIG.

  By twisting the blade surface H2, the burden of twisting the operator's hand can be reduced, and the possible orientation angle of the blade surface can be increased. This will be described with reference to FIG. When worker I cuts hair while standing behind hair Y, in the area opposite to the dominant hand side (the left area of hair I if the right-handed worker), twist the wrist outward. It is necessary to repeat the opening and closing operation of the blade in the state where In addition, even when cutting blades from multiple directions into a bundle of hair drawn from the head, it is necessary to twist the scissors to change the blade surface in various ways, and conventional scissors cause fatigue. It was. For example, in dry cutting, first, the worker I pulls out a bundle 8 of hair of the hair person Y from the head as shown in FIG. Cut the corners of the ends of the hair bundle 8 and arrange the hair in a pencil shape. The cut hair bundle 8 is released. Pull another bunch of hair out of the head again, cut the corners of the hair ends, and cut this hair bunch into a spire. Repeat this.

  Specifically, as shown in FIG. 14, when cutting the blade from two directions C1 and C2 (in the direction of the arrow in FIG. 14) in order to cut off symmetrical two corners of an arbitrary bundle of hair bundles 8, the conventional scissors are used. In order to achieve this, the wrist needs to be twisted greatly. This is because, in the conventional scissors, the finger ring surface h1 and the blade surface H2 are substantially the same, and therefore it is necessary to twist the finger ring surface h1 by an orientation angle equivalent to the orientation angle of the blade surface H2, which places a heavy burden on the wrist. In particular, due to the wrist structure, the operation of twisting the wrist outward is difficult compared to the operation of twisting inward, and the possible twist angle is also reduced. For example, in the case of FIG. 14, it is necessary to twist the wrist to the right to achieve the blade surface in the C1 direction. In addition, conventional scissors require an opening / closing motion while pulling up the finger ring on the moving blade side. Therefore, a further burden arises.

  On the other hand, the hairdressing and scissors scissors 1 of Example 1 can reduce the burden on the wrist and orient the blade surface outward. Specifically, if it is intended to cut in the C1 direction in FIG. 14, the finger ring surface H1 required to achieve the blade surface H2 parallel to the C1 direction is not the same as the blade surface H2, and the operator side It is located in the foreground. That is, as described above, the blade surface H2 has already been rotated in the outer direction (rightward direction in FIG. 14) in the reference gripping posture, and thus the finger ring surface H1 necessary to achieve the degree of rotation of the blade surface H2. Twisting is reduced. As a result, as shown in the figure, the actual wrist twist is reduced and the burden on the wrist is significantly reduced.

  Further, in order to achieve the blade surface H2 in the C2 direction, it is necessary to configure the finger ring surface H1 as shown in FIG. The blade surface H2 in the C2 direction can be achieved by twisting the wrist inward. However, as shown in the drawing, if the hairdressing / cosmetic scissors of the first embodiment are used, the actual finger ring surface H1 twist direction is larger than the blade surface H2, that is, compared with the conventional hairdressing / cosmetic scissors where the blade surface and the finger ring surface are the same. As a result, the twist of the wrist constituting the finger ring surface is increased. However, as described above, it is easier to twist the wrist in the inner direction than in the outer direction, so even if the degree of twist in the inner direction slightly increases, the magnitude of the load does not change much.

  As described above, it is possible to increase the orientation angle at which the blade surface can be realized by reducing the necessity of twisting in the outward direction, which has a heavy burden on wrist twist. FIG. 15 is an explanatory view showing a region in which the blade surface H2 can be oriented. In FIG. 15, the shaded area indicates the area R1 that can be realized with the conventional barber / cosmetic scissors, while the dot area indicates the area R2 that can be realized with the barber / cosmetic scissors of the first embodiment. However, since the limit of the twist of the wrist has individual variations, there is a deviation in the region where the blade surface orientation can be realized, but here, based on the region where the conventional hairdressing and scissor scissors can be realized, the theory of Example 1 is used. The blade surface area of the beauty scissors will be described. FIG. 15 is a simplified view of the right-handed worker I and the to-be-haired person Y as seen from above, as in FIG.

  In the conventional hairdressing and scissors scissors where the blade surface H2 and the finger ring surface h1 are the same as described above, the regions where the blade surface H2 and the finger ring surface h1 can be oriented are equal. That is, the region of the finger ring surface h2 that can be realized by twisting the wrist is a region in which the blade surface H2 can be oriented. Therefore, as shown in FIG. 15, the region R1 where the conventional barber / beauty scissors can be oriented is scarce on the left hemisphere side of the object corresponding to the side where the wrist burden is large. On the other hand, in the region R2 where the hairdressing scissors can be orientated in Example 1, since the direction of the blade surface is oriented in the outward direction in advance, this is promoted, and even if the wrist is twisted, a wider range is obtained. Can be cut in the area.

  Further, in the right hemisphere of the subject that is the subject hair Y, it corresponds to a range that can be realized with the wrist twist inside, but as described above, the burden due to the difference in the twist angle of the wrist is not so much affected, There is not much difference in the region between R1 and R2. That is, in the conventional hairdressing scissors, the balance of the region where the blade surface can be oriented is poor on the left hemisphere side where the burden is large and on the right hemisphere side where the burden is light, but this is eliminated with the hairdressing scissors in the first embodiment. A substantially symmetric alignment region can be realized, which is preferable. In addition, since the work area on the left hemisphere side that greatly affects the increase / decrease of the alignment area increases, the total alignment area can be increased even if the alignment area on the right hemisphere side slightly decreases. However, this orientation region can be realized by changing the standing position of the worker I even with conventional scissors. However, the worker I needs to move and is troublesome. With the hairdressing and scissors scissors 1 of the embodiment, it is possible to cut a wide range by reducing the twist of the wrist while keeping the same standing position. Further, since the amount of movement of the worker can be reduced, work efficiency is increased.

As described above, the twisting state of the blade surface by the standard gripping posture depends on the angle A3 (see FIG. 2) formed by the finger ring surface H1 and the blade surface H2. The angle A3 constituted by the finger ring surface H1 and the blade surface H2 is preferably larger than 0 ° and not larger than 90 °, more preferably 5 ° to 80 °. If it is this range, said effect can be acquired effectively. If the angle A3 is small, the degree of twisting of the blade surface is small, and if it is larger than 90 °, the difference between the conventional hairdressing scissors and the hairdressing scissors of Example 1 is not negligible when twisting inward of the wrist. It will be a burden.
Further, the second finger B2 applied to the second finger ring 21 is not limited to the ring finger, and may be any of the index finger, the middle finger, and the little finger. By using the second finger B2 combined with the thumb as an alternative, the gripping posture of the hairdressing scissors on each finger can be changed. That is, the twist angle A3 of the blade surface in the reference gripping state can be adjusted by the selected second finger. In other words, the direction of the blade surface H2 can be changed stepwise with the finger inserted into the second finger ring 21, and the directionality of the blade surface can be widened.
1 to 13 are right-handed barber / scissors, that is, right-handed barber / scissors for use with a thumb on the first finger ring. Needless to say, this hairdressing scissors structure can be used for left-handed hairdressing scissors. That is, the first blade on the moving blade side is superimposed on the second blade, that is, the first blade is located on the remote side from the user. And, as long as the relative position of the finger ring with respect to the blade is held as described above so that the position of each finger ring substantially coincides with the position of the dominant hand, the shape and material of the hairdressing scissors are not particularly limited. And can.

  Furthermore, the hairdressing scissors grasping assisting portion can have various shapes in addition to the curved shape as described above. For example, a hairdressing scissor scissor 20 in which the grip assisting portion is substantially aligned with the extending direction of the blade is formed into a second embodiment, and a front view of the hairdressing scissor scissor 20 is shown in FIG. FIG. 21 shows a state in which the hairdressing scissors 20 in FIG. 19 is gripped. In the hairdressing and scissors scissors 20 of the second embodiment, the same members and structures as those of the hairdressing and scissors scissors 1 of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted as appropriate.

  As shown in FIGS. 19 and 21, the barber / beauty scissors 20 of the second embodiment includes the grip assisting portion 14 on the extension of the second handle 22 as in the first embodiment. Specifically, the grip assisting portion 14 is provided on the other end side of the second handle 22 facing the second blade 23 on one end side. The grip assisting portion 14 has a linear shape continuous from the second handle 22, and the end portion protrudes upward (in the direction opposite to the blade edge) from the second finger ring 21. In the example of FIGS. 19 and 21, the second blade 23, the second handle 22, and the grip assisting portion 14 are formed in a straight line continuously in the longitudinal direction. However, it is not necessary to precisely match the extending directions of these members. For example, the hairdressing and scissors scissors shown in FIG. 23 is a front view of a hairdressing and scissors scissors according to another embodiment of the second embodiment. Compared with the hairdressing and scissors scissors in FIG. The stretching direction is different. That is, the second handle 22 is inclined from the connection area with the second blade 23 to the left side in FIG. 23, that is, in a direction away from the first finger ring 11. Furthermore, the grip assisting portion 14 is provided continuously with the grip assisting portion 14 on the extension of the inclined second handle 22. That is, the shape is separated from the first finger ring 11 toward the distal end side of the grasping assisting portion 14, and thereby a space space between the first finger ring 11 and the second finger ring 21 can be earned. As a result, with the user holding the scissors 20, the third finger B3 between the first finger B1 and the second finger B2 is placed in this space, and the second finger and the third finger It is possible to easily hold the grip assisting portion 14 with the fingers. Alternatively, the first handle 12 and the second handle are inclined by tilting the second handle 22 to the outside (left side in FIG. 23) with the middle position from one end to the other end of the second handle 22 as a fulcrum. It is good also as a form which spaces apart 22 and ensures the space space between the 1st finger ring 11 and the 2nd finger ring 21. FIG. Further, in accordance with the inclination of the second handle 22, the extending direction of the first handle 12 from the first blade 13 and the connection angle between the first handle 12 and the first finger ring 11 are appropriately adjusted, The gripping state can be adjusted. In addition, the grip assisting portion 14 can be composed of the same member as the second handle 22, and the grip assisting portion 14 and the second handle 22 can be connected as separate members so as to be integrated.

  When the operator inserts the first finger B1 and the second finger B2 into the first finger ring 11 and the second finger ring 21, respectively, as shown in FIG. 21, the first finger B1 and the second finger B2 The third finger B3 located between the two comes into contact with the linear gripping assisting portion 14. Specifically, in the form in which the thumb B1 is inserted into the first finger ring 11 and the middle finger B2 is further inserted into the second finger ring 21, the index finger corresponds to the third finger B3, and this index finger B3 is a linear grip assist. It will be in the state which contacted the part 14. FIG. Almost simultaneously with this, the middle finger B2 inserted through the second finger ring 2 also comes into contact with the linear gripping assisting portion 14, so that the index finger B2 and the middle finger B3 can close the linear gripping assisting member 14 tightly. That is, by providing the grip assisting portion 14, the stationary blade 23 side can be stably supported by a plurality of fingers, and efficiency and safety in using the scissors 20 can be improved.

  Further, the hairdressing scissors 20 may add various members or change the shape of the already-described members in order to stably support the stationary blade 23 side. For example, as shown in FIG. 19, the finger pad 16 can be annular. Similar to the finger pad portion 6 of the first embodiment, the finger pad portion 16 is located between the second finger ring 21 and the second blade, and is formed so as to be able to contact at least a part of the finger. Yes. More specifically, the finger pad 16 is fixed between the second finger ring 21 and the fulcrum part 3. The connection region between the finger pad 16 and the second handle 22 is located below the connection region between the second finger ring 21 and the second handle 22. Moreover, it is preferable that at least a part of the inner surface of the finger pad 16 is formed in a shape along the outer surface of the second finger B2. As a result, with the second finger B2 hung on the second finger ring 21, the tip end side of the second finger B2 can be firmly brought into contact with the finger contact portion 16, and as a result, the scissors 20 can be stabilized. It can be gripped.

  Further, the separation distance between the second finger ring 21 and the finger pad 16 is not particularly limited. For example, by fixing the finger pad 16 to a position where it can contact the joint of the second finger B2, the frame of the finger pad 16 is sandwiched between the bent parts of the joint, and the finger pad 16 is placed between the fingers. Can be supported in a posture that lifts from bottom to top. As a result, it is preferable that the scissors 20 can be prevented from falling in the vertical direction when the scissors 20 are gripped with the blade edge down.

  In addition, the connection point between the second finger ring 21 and the second handle 22 and the connection with the center point of the second finger ring 21 are defined as a second finger ring axis t2, and the finger rest 16 and the second handle 22 are similarly formed. A connection point between the connection point and the center point of the finger pad 16 is defined as a finger pad axis t4. The shape surface u1 including the outer shape of the second finger ring 21 can be tilted downward within a range of 0 ° to 30 ° from the surface orthogonal to the second handle 22. That is, as shown in FIGS. 19 and 23, the second handle 22 is preferably fixed to the second handle 22 in such a posture that an angle e1 formed between the second finger ring axis t2 and the extending direction of the blade edge is 60 ° to 90 °. . In addition to this, the shape surface u1 of the second finger ring is rotatable about the second finger ring axis t2. Specifically, as shown in FIG. 20, while maintaining the angle e1 formed between the second finger ring axis t2 and the blade edge direction in the above range (60 ° to 90 °), the second finger ring axis t2 as an axis, The shape surface u1 of the finger ring containing the axis t2 can be a surface u1 ′ rotated by a rotation amount v toward the front or back in the drawing. That is, as shown in FIG. 20, the second finger ring 21 is fixed at a position rotated in the front or back direction in the drawing around the connection point with the second handle 22. The rotation amount v of the shape surface of the second finger ring 21 is set in a range of 0 ° to ± 10 ° symmetrically with respect to the second handle with respect to the plane u1.

  Further, the fixed position of the finger pad 16 can be varied within the same range as the second finger ring 21 described above. That is, the finger pad 16 has a shape surface u2 containing the outer shape of the finger pad 16 with the finger pad axis t4 as an axis while maintaining an angle e2 formed with the extending direction of the blade edge at 60 ° to 90 °. The surface u2 ′ can be made to be rotated by the above-described rotation amount v in the front or back direction in FIG. The finger pad 16 is configured so that the normal of the shape surface u2 containing the outer shape of the finger pad 16 is substantially the same as the central axis of the second finger ring 21, and the normal of the finger pad 16 is the second finger ring. It is preferable that the second finger B2 is placed so as to substantially coincide with the insertion direction of the second finger B2 hung on both the finger rest part 21 and the finger pad 16. In other words, it is preferable that the shape surfaces u 1 and u 1 ′ of the second finger ring 21 and the shape surfaces u 2 and u 2 ′ including the outer shape of the finger pad 16 are substantially parallel. By setting the arrangement position or relative position of the second finger ring 21 and the finger pad 16 as described above, the hairdressing and scissors scissors 20 substantially matched with the work posture of the hand can be obtained. Therefore, the hairdressing scissors 20 can be gripped naturally, and fatigue due to the use of the scissors can be minimized. On the other hand, as shown in FIG. 22, the second finger ring 21 and the finger contact portion 16 may be configured to approach each other on the far side from the second handle 22. Thereby, since the normal direction of each shape surface in the 2nd finger ring 21 and the finger contact part 16 differs, it becomes easy to engage with the finger to insert. In other words, it is difficult for the scissors 20 to fall off the finger and the safety of use is increased, and at the same time, the movement of the cutting edge can be controlled effectively. Specifically, it is preferable that the finger contact portion 16 increases the angle e2 formed with the extending direction of the blade edge as compared with the second finger ring 21 (e2> e1). That is, it is preferable to reduce the downward inclination of the finger pad 16. This is because it is possible to easily abut the finger firmly below the finger pad 16 on the outer surface (surface including the nail) of the second finger B2. As a result, when the blade edge is lifted upward, it can be easily pressed outward around the contact area on the lower side of the finger pad 16. By this pressing, the finger pad 16 moves forward and the cutting edge easily rises, and this posture can be easily supported. More specifically, the above-described effect can be obtained by setting the finger contact portion axis to a position t4 ′ inclined upward in the range of 0 ° to 5 ° with respect to the position t4 parallel to the second finger ring axis t2. This is preferable. That is, it is preferable that the angle s formed between the second finger ring 21 and the finger pad 16 is in the range of 0 ° to 5 °. Furthermore, it is preferable that the finger pad 16 has a reduced shape of the second finger ring 21, that is, an annular shape with a reduced diameter in the example of FIG. As a result, the contact area between the second finger B2 and the finger pad 16 can be increased, and the scissors 20 can be further prevented from falling off from the second finger B2 hanging on the second finger ring 21.

  On the other hand, the finger pad 16 may have a continuous annular shape or a shape of at least a part of an annular circumference, that is, a fragment shape. This example is shown in FIG. 24 is a semi-annular shape in which a part of the annular shape is cut out, and is formed in a substantially symmetrical shape with the connection portion with the second handle 22 as the center. In other words, the finger rest portion 26 is formed in a semicircular shape only on the side close to the second handle 22 and has an arc shape lacking an outer semicircular shape facing this. In other words, the finger rest 26 is formed around a region where stress is applied when the grasping assisting portion 14 is tightly attached between the second finger and the third finger. Moreover, it is preferable that the finger contact part 16 is made into the circular arc shape containing the area | region which can contact at least with the belly of the finger B2. As a result, the tip of the second finger B2 can be easily hooked on the finger rest 16 and a contact area with the finger can be earned.

  Thus, in the form in which the finger rest 26 is formed only in the region effective for fixing the stationary blade 23 side, only a part of the periphery of the finger is used as the grip assisting portion 14 instead of the entire circumference of the finger. Can contact. As a result, regardless of the thickness of the operator's finger, the second finger B2 and the finger contact portion 26 can always be in close contact with each other. In other words, the second finger B2 is used as the finger rest unit without depending on the difference in the diameter of the finger selected as the second finger B2 on the second finger ring 21 and the difference in the thickness of the finger by various workers. The grip assisting portion 14 can be fixed by being brought into firm contact with 26.

  Further, the hairdressing and scissors scissors 20 of the second embodiment can further stabilize the gripping state by further providing a second gripping auxiliary portion 24 separately. For example, in the example of FIGS. 19 to 24, the second grasping assisting portion 24 is disposed between the first finger ring 11 and the second finger ring 21. When the operator holds the barber / scissors 20, the third finger B <b> 3 can be brought into contact with the second holding assist part 24. In other words, the gripping position of the third finger B3 is positioned by the second grip assisting unit 24 supporting the third finger B3, and as a result, the second handle 22 is firmly held by the third finger. Can be stationary. Specifically, the second grasping assisting part 24 is connected to a part of the second finger ring 21. However, the connection position is not limited to the second finger ring 21, and can be on the second handle 22, for example. Further, the second grip assisting part 24 is formed in a linear shape protruding from the second finger ring 21 toward the first finger ring 11 side. Then, as shown in FIG. 21, the first finger ring 11 and the second finger ring 21 are put with the thumb B1 and the middle finger B2, respectively, and the abdomen side of the index finger B3 is brought into contact with the second grasping assisting portion 24. . More specifically, the grip assisting portion 24 can be narrowed and supported firmly by folding the first joint of the index finger B3. By providing the second grip assisting portion 24 in this manner, the operator stably holds the second handle 22 on the stationary blade 23 side, and the second handle 22 is also in the open or closed state of the scissors. Can be fixed so as to be substantially stationary.

(Position of the second finger ring)
Further, as described above, the hairdressing scissors can be fixed so that the second finger ring 21 can be rotated clockwise as viewed from the positive direction of the z-axis as shown in FIG. is there. As a result, the relative position of the first finger ring 11 and the second finger ring 21 such as a separation distance and a configuration angle thereof is adjusted, so that the operator can easily hold the scissors 1 and the posture of the hand to the hand posture. Can be adapted. The connection position of the first finger ring 11 will be described below.

  FIG. 25 is a plan view of the barber / beauty scissors 20 according to the second embodiment observed from the blade edge side. Here, the fulcrum part 3 is set as a reference point G, and the cutting edge direction (from the back to the front in FIG. 25) in the closed blade state from the reference point G is set as the z axis. Further, a straight line that passes through the reference point G and is orthogonal to the rotation surface of the blade is taken as the x-axis. In addition, a straight line that passes through the reference point G and is parallel to the rotation surface of the blade and orthogonal to the x-axis is defined as the y-axis. In the x-axis, the second blade 23 side (the right direction in FIG. 25) is the positive direction of the x-axis, and the upward direction in FIG. 25 is the positive direction of the y-axis. That is, FIG. 25 is an xy plan view of the barber / scissors 20 of the second embodiment. The direction from the reference point G to the center point J of the shape surface of the second finger ring 21 is defined as the fixing direction m of the second finger ring 21. The angle formed by the fixing direction m of the second finger ring with the negative y-axis direction is referred to as a second finger ring connection angle θ.

  The hairdressing scissors 20 is configured in a posture in which the first finger ring 11 is arranged in the first quadrant and the second finger ring 21 is located in the third quadrant or the fourth quadrant in the xy plan view of FIG. ing. Specifically, the connection angle θ of the second finger ring 21 is in the range of 0 ° to 120 °, preferably 0 ° to 90 °, more preferably 30 ° to 60 °. Within this range, even if the second finger B2 is the index finger, middle finger, ring finger, little finger, or there is a slight difference in the length or thickness of the fingers B1 and B2 applied to the finger ring by the operator. However, it is possible to use the hairdressing and scissors scissors 20 that allow the operator to naturally grip these variations. In other words, the operator's appearance of holding the hairdressing scissors 20 is that there is a slight shift in the posture of the hand, such as the distance between the first thumb B1 and the second finger B2, the height difference of the fingers, and the configuration angle. Arise. This is because the relative positions of the first finger and the second finger are slightly different due to the difference in the shape of the finger selected as the second finger B2 or the difference in the shape of the finger unique to the operator. . Therefore, if the connection angle θ of the second finger ring 21 with respect to the horizontal direction of the blade surface is set to the above range, the operator's work appearance will be improved regardless of the selected finger. Since the movement can be similar, scissors can be easily grasped.

  Further, when the scissors 20 are used by specifying the second finger B2 as any one finger, it is preferable to position the first finger ring 11 and the second finger ring 21 in more detail. Thereby, the structure of the hairdressing scissors 20 can be further matched to the gripping posture constituted by the first finger B1 and the second finger B2. For example, when the second finger B2 is the middle finger, the connection angle θ of the second finger ring 21 is preferably about 45 °. As a result, hairdressing and beauty scissors that are easy to grip and work can be obtained, and safety and efficiency can be improved.

  In addition, the hairdressing scissors can be provided with stoppers of various shapes that can determine the closing position of the blade as described in the first embodiment. For example, in the hairdressing and scissors scissors 20 of FIGS. 19 to 23, a convex portion protruding from a part of the second handle 22 to the first handle 12 side is provided, and this is used as a stopper 17. When the first finger ring 11 is rotated to move from the open blade state to the closed blade state, the first handle 12 is brought closer to the second handle 22 side, and the first handle 12 is further moved to the tip of the stopper 17. Abut. At this contact position, the displacement of the finger ring 11 stops and the rotation of the blade also stops.

  Further, the stopper and the receiving portion abutted against the stopper can be shaped to fit each other. For example, the hairdressing and scissors scissors shown in FIG. 26 includes a stopper 7 protruding in a prismatic shape from a part of the first finger ring 11 and a receiving portion 18 that comes into contact with the stopper 7 and stops the movement of the stopper 7. 26 is located at the tip of the curved second handle 22, and has a shape cut out along the protruding shape on the stopper 7 side. Specifically, the receiving portion 18 is stepped so that the outer surface forming a right angle on the stopper 7 side is in contact with the inner surface of the notched portion of the receiving portion 18. The protruding shape of the stopper 7 is fitted to the stepped notch portion of the receiving portion 18 so that the hairdressing scissors are in a closed blade state. In this way, in the contact portion, it is preferable that the contact members are formed in a fitting shape so that the contact position can be stabilized. Further, in the above example, the convex portion side and the concave portion side of the contact portions that are fitted to each other are made to correspond to the stopper and the receiving portion, but the stopper may be the concave portion side and the receiving portion may be the convex portion side. Needless to say. Further, in the hairdressing and scissor scissors in FIG. 26, as in the example in FIG. 23, at least a part of the second handle 22 may be inclined in a direction away from the first finger ring 11.

  The hairdressing scissors of the present invention can be applied to hairdressing scissors.
