調節しうる鋏を提供することを目的とする。[Detailed description of the invention] The present invention relates to scissors, particularly scissors suitable for hairdressing.The scissors body is easy to disassemble, assemble, adjust, and clean, and the function as scissors is not diminished.
It is an object of the present invention to provide scissors in which the blade surfaces of scissor bodies maintain substantially constant contact pressure with each other from the blade base to the cutting edge, and the user can adjust the contact pressure at any time.

構成となつている。 Conventional scissors, especially hairdressing scissors, are fixed to one scissor body by cutting a female thread directly on one fulcrum of the scissor body and inserting a screw with a slightly larger thread diameter than the female thread. The tip of the screw is caulked and fixed, and the other scissor body is rotatably supported by the screw, so that both scissors bodies can be opened and closed appropriately and smoothly. It is becoming.

れるに至る。 The conventional scissors, especially hairdressing scissors, have many opportunities to be disassembled and assembled, unlike ordinary general-purpose scissors, and the frequency of disassembling and assembling the scissor body and adjusting the screw insertion position is high. The screw engagement between the female thread and the screw thread becomes loose, and the screw is no longer fixed to one of the scissor bodies, and the screw may rotate during the opening/closing operation of the scissors. The gap space at the fulcrum changes during the opening and closing operation, expanding or contracting, causing improper contact between the blade surfaces of the two scissor bodies or separation of the two scissor bodies, and in extreme cases. Both scissor bodies may be disassembled, leading to the loss of their function as scissors.

動力を必要とし、その結果、ビスの頭溝を破損し
たり、時にはビスが捻切れることも生じる。 When tightening the screw between the female thread of the scissor body and the screw in order to prevent the screw from becoming loosely fitted, if the alignment is too tight, it may cause problems during disassembly and adjustment.
Each time a screw is opened or tightened, a large rotational force is required by a screwdriver, and as a result, the head groove of the screw may be damaged, and sometimes the screw may become twisted.

係止体が用いられる。 When assembling general-purpose scissors, depending on the function and purpose of use, instead of using screws such as those mentioned above, the scissors body is used as a fulcrum locking body, and a rivet or the like is used between both scissors bodies to secure the purpose of use. There are many types that are fixed with appropriate space gaps depending on the situation. In these general-purpose scissors, once the two scissors bodies are locked, there is almost no need to adjust the gap between the scissors bodies, so a fixed locking body is used.

や、ねじ調節を行なう頻度が極めて大である。 In the hairdressing industry, each user of scissors has a unique method of operating the scissors for the purpose of styling hair, and in order to respond to the delicate requests of customers undergoing hairdressing. The gap between the two scissor bodies is often adjusted based on the degree of sharpness of a certain standard and ease of use. Therefore, the frequency of disassembling and assembling the scissor body and adjusting the screws is extremely high.

る。 Originally, the blade surfaces of both scissor bodies of scissors were formed to be slightly curved toward the inner surface, which is the facing surface, for their function. until it closes completely.
By keeping both blade surfaces in good contact with each other, it has a cutting function as scissors.

もある。 In general-purpose scissors, both blade surfaces contact well in the state of the maximum opening angle, and in the process of completely closing down to the cutting edge, due to the elasticity of the blade surface of the scissor body itself,
The state in which the blade surfaces are pressed against each other is maintained. On the other hand, some pruning shears used in the flower arranging and landscaping industry have limited uses, but if you open the shears without applying force or performing any manipulations on the shears, both pruning shears will break. The gap between the fulcrum part of the scissor body is large,
The blade surfaces do not come into contact with each other, and when using the scissors, the delicate twisting of the scissor body with the fingertips and the application of pressure bring the two blade surfaces into contact, and while maintaining this contact state, the blades open and close for cutting. Some add manipulation.

法を用いて使用している。 Hairdressing scissors are used by hairdressers to create a certain hairstyle while cutting hair, so they are more sensitive to the pressing force of the double-edged surface than the general-purpose scissors mentioned above.
In other words, the contact pressure is small, and the gap between the two scissor bodies is adjusted so that during opening and closing operations, the two blade surfaces do not come into contact at a position with a large opening angle, and the two blade surfaces only start contacting just before the cutting edge is completely closed. When cutting with these scissors from the maximum opening angle, the hairdresser must perform a unique operation in which the two blade surfaces start contacting from the maximum opening angle by using the fingers. It is used according to the law.

つてしまうことがあり、この現象を業界では「刃
喰い現象」と呼んでいる。 When using scissors as described above, the load applied to the blade surface is greater than when using general-purpose scissors.
Large amounts of abnormal wear occur in some areas,
It becomes necessary to sharpen the blade more frequently, and it becomes necessary to adjust the screw of the fulcrum locking body and to disassemble and assemble the scissor body as necessary. When the gap between the two scissors bodies at the fulcrum part is adjusted to be large, or when the scissors have a large inward curvature of the blade surface of both scissors bodies, the opening angle is large, that is, the blade base If the two blade surfaces are brought into pressure contact by twisting the scissor body at a position close to the scissors body, the two blade surfaces may come into contact with each other with the blades cutting beyond the set blade angle.
In this case, the object to be cut (hair in the case of hairdressing)
In addition to cutting, the cutting edge of the other blade may also be cut off, and this phenomenon is referred to in the industry as the ``blade-biting phenomenon.''

通常この現象は鋏としての機能上、および切断
操作上支点部に近い刃元部分に多く発生する。 Normally, this phenomenon often occurs at the blade base near the fulcrum for the scissor function and cutting operation.

とが多い。 When the gap between the two scissors bodies at the fulcrum part is large, the structure of the fulcrum part is inappropriate for the contact movement of the blade, or the scissors have an unnecessarily large inward curvature of the blade surface, what is called in the industry When the scissors are used as loose scissors, small blade-eating phenomena often occur not only at the base but also over the entire blade surface up to the tip, and the scissors lose their ability to function well in a short period of time. I often get caught.

従つて、実際に被切断物を切断することなく行

来から理美容師の間では厳禁され、から鋏を極度
に嫌う習慣すら存在する。 Therefore, the opening and closing operation of scissors that is performed without actually cutting the object to be cut, the so-called "kara scissors" operation, has traditionally been strictly prohibited among barbers and hairdressers, and there is even a habit of extremely hating the scissors.

ともなる。 In addition, when cutting hair, hair chips enter the fulcrum from the concave surfaces inscribed on both blade surfaces and other surrounding areas, stay in the fulcrum gap, and the shaft of the fulcrum locking body due to the opening and closing movement of the scissors. It moves within the gap space as it rotates about its center. The gap space of the scissors during the opening/closing operation is approximately constant, and as mentioned above, when the scissor body is twisted in an attempt to maintain contact between the two blade surfaces during the opening/closing operation, the gap space at the fulcrum part changes to the area where the two blade surfaces contact each other. As the chips move, they are brought into eccentric contact while changing the location from time to time, so that the space with a large gap also moves around the axis of the fulcrum locking body, allowing chips to remain in the gap space. Occasionally, chips may be held as they are in uneven positions in the gap space, and in this case, the cutting angle of the contact point between the two blade surfaces becomes unstable, leading to the phenomenon of blade gouging or improper local wear. It also becomes a factor that promotes this, and also impedes smooth opening and closing operations, making it impossible to cut accurately.

より長期の滞留を許す因となる。 If the hair debris that has entered the gap space of the fulcrum part is quickly removed, the above-mentioned problem will not occur, but in addition to the unnecessarily large gap space that exists from the beginning of the opening and closing operation, it is difficult to smoothly open and close the scissors body. When lubricating oil is applied between the sliding surfaces of the fulcrum part, the viscosity of the lubricating oil traps hair debris that has entered the gap space.
This causes the particles to stay for a longer period of time.

もある。 Some scissors have a washer made of an elastic thin layer of rubber, synthetic resin, leather, etc. interposed in the gap space to prevent chips from entering and ensure smooth opening and closing operations regardless of the size of the opening angle. It is necessary to add a unique opening/closing operation to the cutting operation, making the operation complicated.
In addition, while maintaining smooth operation, the inward curvature of the blade surface has been reduced to reduce the occurrence of cross-cutting of the blade surfaces at inappropriate blade angles and uneven wear. Some scissors adjust the screw so that the gap space at the fulcrum is relatively narrow, but once the gap space is narrowed and chips enter the gap space, it is not necessarily easier to remove the chips than with conventional scissors. Moreover, the narrower the gap space, the more likely the chips will stick to the gap space, and sometimes the chips will become crushed and adhere all over the gap space.

る。 For the aforementioned reasons, it is necessary from time to time to disassemble and clean hairdressing scissors. For this reason, in recent years, some models have appeared in which the scissor body is assembled by attaching a replaceable nut to the fulcrum part of the scissor body without directly cutting a screw, and there are also screws that are made of an elastic material such as synthetic resin that is softer than metal. Mounted scissors have also appeared, and due to the elasticity of the screw, some are expected to have somewhat greater cushioning and spring effects than conventional metal ones.

る。 Furthermore, in order to cope with the frequent opening and tightening of screws such as screw adjustment and disassembly of the scissor body, the screw is larger than a normal nut and has a knurl carved on the circumference and can be opened with a fingertip. Some have been installed.

あり、その構成について、以下図面により説明す
る。 In all of the scissors described above, a gap space is always provided so that the scissors body can smoothly open and close at the fulcrum portion. Further, in the scissors equipped with a knurled screw, since the knurled screw is larger than a normal nut, the fulcrum portion is provided with a large protrusion, which is undesirable for use as hairdressing scissors as it becomes a hindrance to the operation. The present invention overcomes the drawbacks of the various types of scissors mentioned above and provides scissors particularly suitable for hairdressing.The configuration thereof will be explained below with reference to the drawings.

あつてもよい。 In the first embodiment, as shown in FIGS. 1 and 2, the scissors 1 consists of scissors bodies 2 and 3, and a fulcrum that rotatably locks the scissors bodies 2 and 3 to each other at a fulcrum part 4. As shown in FIGS. 3 and 4, the locking body 5 is attached to both the scissors bodies 2 and 3 from one side of the fulcrum portion 4 of the scissors bodies 2 and 3 (in the illustrated example, the side of the scissors body 2). A screw 6 is loosely fitted into the drilled fulcrum holes 15, 15, and a screw 6 is screwed onto the outside of the fulcrum part 4 of the other of the scissors 2, 3 (the scissors 3 in the illustrated example). The back surface 9 of the head 8 of the screw 6 is rotatable in the bottom surface 11 of a shallow cavity 10 recessed outside the fulcrum portion 4 of the one scissor body 2. The small mainspring nut 7 has a strip-shaped leaf spring body such as phosphor bronze wrapped in a multiple cylindrical spiral shape, and the leaf spring body is mounted on the cylindrical inner surface of the innermost central winding opening 12. A threaded portion 13 consisting of a female thread into which the screw 6 is screwed is cut over the entire width, and the thread diameter of the threaded portion 13 is equal to that of the screw 6.
The diameter of the screw is slightly smaller than the diameter of the screw. Note that the mainspring nut 7 is attached to the scissor body 3 as shown in FIG.
A shallow concave cavity 14 is formed on the outside of the fulcrum part 4 of the scissors 1 , and the spring nut 7 is screwed into the concave cavity 14 so that the spring nut 7 does not protrude too much from the side of the fulcrum part 4 of the scissors body 3 . Although it is preferable that the concave cavity 14 is not necessarily obstructive in the opening/closing operation of the spring nut 7 and does not cause excessive expansion of the spring nut 7, the spring nut 7 is rotatably supported relative to the scissors body 3. It would be fine if it had been done. The head 8 of the screw 6 may have a hexagonal head as shown in Fig. 4, but it may be provided with a tool locking portion such as a groove or socket that can lock a rotating tool such as a spanner or screwdriver. The head 8a may have a round shape as shown in FIG. 5, or may have the shape shown in FIGS. 6 and 7.

へは力は印加されない。勿論緩むこともない。 To assemble the scissors 1, use the fulcrum holes 15, 15 of the scissors bodies 2, 3.
, insert the screw 6 from the scissors body 2 side, attach the spring nut 7 to the scissors body 3 side, and
is screwed into the threaded portion 13 of the winding opening 12 while slightly pushing and expanding the spring nut 7. The mainspring nut 7 is attached in such a direction that the mainspring nut 7 is pushed open when the screw 6 is screwed in. Since a constant tightening force is applied in the radial direction by 7, the fulcrum locking body 5 is rotatable with both scissors bodies.
a scissors body 2 that can freely open and close relative to the body;
Unless the fulcrum part 4 of the scissors 2 and 3 is improperly locked with the fulcrum locking body 5, the relative opening and closing movement between the scissors bodies 2 and 3 will cause the fulcrum locking body 5 to No force is applied between the spring nut 7 and the screw 6 in the tightening direction. Of course it won't loosen up.

締力は印加されない。 Furthermore, even if an improperly fixed state occurs between the scissors body 2 or 3 and the fulcrum locking body 5, for example, one of the screws 6 of the fulcrum locking body 5 and the scissors body 2 or 3 may be in a fixed state. Even in this case, if the other mainspring nut 7 and the scissors body 3 are not in a fixed state, the mainspring nut 7 is rotated with the rotation of the screw 6, so there is no space between the screw 6 and the mainspring nut 7. , no screwing force is applied.

手段を用いる。 Also, regarding the direction in which the screw 6 and the mainspring nut 7 are loosened and separated, the tightening force is always applied to the screw 6 from the mainspring nut 7, and the mainspring nut 7 is rotated in the direction of loosening the mainspring nut 7 from the screw 6. When I try to move the mainspring nut 7, screw 6
Since rotational force is applied in the direction of tightening, the tightening force is always increased as the tightening force increases, so the spring nut 7 cannot be easily loosened from the screw 6. When it is desired to loosen the spring nut 7 from the screw 6, a device is used to release the winding force at the winding mouth 12 of the spring nut 7 and push it outward from the center.
use means.

用をなさなくなることはない。 As mentioned above, while opening and closing scissors 1,
The relative position between the screw 6 and the mainspring nut 7 does not change, so that both 6 and 7 maintain a fixed relative position. Even if the fixed state between the screw 6 and the mainspring nut 7 is frequently changed, the engagement and disengagement of both 6 and 7 is repeated, and the assembly of the scissors 1 is repeated frequently, the mainspring nut 7, which is elastic, will always maintain its elasticity. Since the spring nut 7 is restored within a certain range and maintains its normal state as a nut, the spring nut 7 will not be deformed or the screws will become loose, and the nut will not become useless.

である。 In the second embodiment, as shown in FIG. 5, the spring nut 7a of the fulcrum locking body 5 that locks the scissors bodies 2 and 3 to each other touches the outer surface of the fulcrum part 4 of the scissors body 3 at the outer peripheral end. The second embodiment has a conical coil shape in contact with the second embodiment, and the screw 6 and other configurations are the same as in the first embodiment.

らない。 In this embodiment, various effects of the mainspring nut 7 of the previous embodiment are achieved, and the threaded portion 13 of the mainspring nut 7a is structured to protrude outward from the axis in a conical shape, so that the scissors 1 When the scissors are at their maximum opening angle, the screws 6 are tightened to a point where no gap space is created between the fulcrum parts 4 of both scissors bodies 2 and 3, and the scissors bodies are held in a bonded state in which they are in deeper contact than the bonded position of conventional scissors. Also, as the scissor bodies 2 and 3 are closed together from the maximum opening angle position, the blade surfaces of both scissors bodies 2 and 3 close in sliding contact according to the inward curvature of the blade surfaces, and at the same time, the fulcrum Although the gap space between the scissors 2 and 3 of the portion 4 increases, the protrusion of the center of the spring nut 7a decreases by the amount that this space increases. Therefore, even if both scissors bodies 3 are brought into contact and tightened at the maximum opening angle, the opening and closing movement of the scissors 1 will not be hindered at all.

となる。 Conventionally, as the scissors bodies 2 and 3 open from the closed position, the gap space at the fulcrum gradually increases, but in this embodiment, as described above, the spring nut 7a is provided. Therefore, the increasing gap space can be absorbed and reduced by the spiral nut 7a protruding conically, and the blades of both the scissors 2 and 3 as the angle closes from the open angle position. Since the increase in the gap space of the fulcrum part 4 caused by the superposition of the inward curvature of the surface is compensated for by the conical depression of the spring nut 7a, unlike the conventional one, the operator can The two blade surfaces are always in contact with each other, regardless of the opening angle position during the opening and closing movement of the scissors, without any manual operation. By appropriately selecting the spring strength in the axial direction of the above-mentioned mainspring nut 7a, it is possible to obtain scissors that have the function of always opening and closing more smoothly, making it possible for any person to easily open and close the scissors.

ことになる。 As mentioned above, among the unique operating methods of conventional scissors using the operator's fingers, the force of contact between the blade surfaces can be reduced by eliminating the need for the operator to consciously twist the blades slightly to bring them into contact when opening the scissors. However, scissor body 2,
During the process of opening/closing movement in step 3, the opening angle is constant at any opening angle position, and the cutting angle of both blade surfaces at the time of contact is also close to constant and stable, so the crossing of the double blade surfaces at a natural cutting angle and As a result, the frequency of occurrence of blade wear and reduction in blade bite is reduced, and as a result, the scissors can maintain their sharpness and good cutting condition for a longer period of time. By maintaining this good condition, for those who use scissors, the unique operation of the hands and fingers, which is the most important technically and has determined the superiority or inferiority of the technique, will be simplified, and the skill of the person who uses the scissors will be improved. You will be freed from the time and effort required to learn and the hassle of adjusting the sharpness of scissors.

空間での固着は生起しない。 Furthermore, when fine chips (hair chips in the case of hairdressing) generated by the cutting operation of scissors invade the periphery of the fulcrum locking body 5 and the gap in the fulcrum part 4, conventionally, there is a large amount of space in the above-mentioned areas. Because of this, it is easy for chips etc. to enter, causing various troubles as mentioned above, and in the end the scissors had to be disassembled for cleaning. However, with the configuration of this embodiment, the opening angle of the scissors can During the closing angle operation process, there is hardly any gap space between the scissors bodies 2 and 3, or even if it does, the gap is minimal, so it is difficult for chips etc. to enter.
Furthermore, even if the scissors enter, the action of the spring nut 7a as a spring creates a gap space equal to the thickness of the accumulated chips, etc., allowing the smooth opening and closing movement of the scissors to continue. No fixation occurs in space.

The chips and the like do not remain in the gap space, but are gradually moved outward in the radial direction, and are finally discharged outside the gap space.

鋏の開閉動作が出来なくなることすらある。 As mentioned above, the intrusion of chips, etc. into the area around the gap between the scissors and the scissors 3 is prevented by the spring nuts 7 and 7.
By wearing a, this is less likely to occur than with conventional scissors, and even if it does, the cutting debris will be quickly discharged. In this case, it may not always be possible to discharge the intruded chips etc. sufficiently. Examples of the causes are as follows: (a) The degree of inward curvature of the blades of both scissors bodies 2 and 3 of the scissors,
In the case of scissors that are formed small in advance and that almost no gap space is created on the inscribed surface from the cutting edge of both blades to the fulcrum part 4 even when both blades are closed together, When the protrusion height of the sliding floor part 17 of the fulcrum part 4 protruding from the inscribed surface of the scissors bodies 2 and 3 is smaller than the opening position of the fulcrum hole 15, C. Both scissors bodies 2 , 3, if the sliding area of the sliding floor part 17 of the fulcrum part 4 of the scissors is wider than necessary, d. The sliding surface has unevenness,
If the scissors are not flat and have a shape that causes wobbling during the opening and closing operation of the scissors, or that chips etc. may accumulate in the recesses of the sliding surface of the sliding bed section 17, the following causes may occur. In some cases, the above-mentioned causes are combined, and in some cases, the degree of closeness of the sliding surface of the sliding floor part 17 is good, and the gap space of the fulcrum part 4, which should originally be secured to some extent, is If there is no
Although there is little chance of chips etc. entering between the sliding surfaces, once the chips etc. enter between the sliding surfaces, it becomes difficult to remove the intruded chips, etc., and in some cases, the sliding surfaces may stick together.
You may even be unable to open and close scissors.

て下記のごとき事態が生ずる。 In addition, considering the causes of cutting work, hair cutting work in the hairdressing industry has recently become more
First, by pre-wetting the hair with water or an aqueous solution containing a humectant, or a dry fixing agent such as a setting lotion, the hairdresser can get an idea of the shape of the hairstyle and the desired hairstyle settings of the customer. At the same time, the hair is swollen and softened to make it easier to cut. However, in the cutting operation that is carried out after such preparatory work, the following situations occur regarding cuttings and the like.

前述の諸原因から、鋏の両鋏体の支点部間隙に
侵入した切屑が容易には支点部から排出されない
場合も生起しうる。 Due to the above-mentioned reasons, there may be cases where chips that have entered the gap between the fulcrum portions of both scissor bodies of the scissors are not easily discharged from the fulcrum portions.

前述の切屑の排出をより容易とするためには、
下記のごとき構造を支点部に付加するとよい。 In order to make the above-mentioned chip evacuation easier,
It is recommended to add the following structure to the fulcrum part.

A plurality of spiral grooves 25, 25 are provided in a radial manner and extend in the same direction around the center. As shown in FIGS. 11 and 12, the shape of the groove 25 is such that the inner surface 26 of the spiral line (the side near the fulcrum hole 15) is steep, and the outer surface 27 is carved with a gentle slope. has been done.

隙空間に侵入、挟持される切屑は、鋏の開閉運動
の度毎に、外側へ向つて押出されていく。 When the scissors bodies 2a, 3a are assembled into a scissor, the grooves 25, 25 carved in the inscribed surface of the fulcrum portion 4 have a structure in which they face each other and intersect. Said groove 2
5 and 25 are in a state where they always intersect during the opening and closing movement of the scissors, regardless of the fluctuation of the opening angle, and the inner surface 26
Since the outer surface 27 has a gentle slope, the chips that enter the gap space of the fulcrum part 4 including the sliding floor part 17 and are caught will be removed every time the scissors open and close. It is pushed outward.

In the case where the groove 25 has a spiral line shape in the direction shown in FIG. The intersection points of the side surfaces 26 are pushed radially outward from the center of the fulcrum hole 15, and when rotated in the closing angle direction, the outer surface 2 of the groove 25
7 has a gentle slope, the chips roll in the gap space in the same circumferential shape from the center of the fulcrum hole 15.

しめるものであつた。 If the spiral line of the groove 25 is in the opposite direction, chips will be discharged outward every time the scissors are rotated in the closing angle direction. Another function of the groove 25 is to retain lubricating oil. The sliding floor portion 17 is slightly protruded on the opposite side of the blade portion 24 around the fulcrum locking body 5 on substantially the same circumference, and
When both scissors bodies 2a, 3a rotate, both sliding floor parts 1
7 and 17 are rotated while contacting each other, and the cutting blades 28 and 17 are rotated while contacting each other, and the cutting blades 28,
It is responsible for assisting the pushing of 28 people,
Therefore, it is desirable to lubricate the contact surface to enable smooth sliding, but in the conventional sliding floor section 17, the sliding surface easily runs out of oil, increasing frictional resistance. Ta.

立つ。 The above-mentioned grooves 25 become places where lubricant can accumulate, and when the scissors are opened and closed, both scissors bodies 2
In order to change the intersection position of the grooves 25, 25 where the grooves a and 3a intersect, the lubricant in the grooves 25 is removed from the sliding floor 17.
The scissors can be gradually spread outward over the entire surface of the scissors 2a and 3a, and fine powder and chips generated by the wear caused by sliding of the scissors 2a and 3a are discharged outward along the grooves 25. Therefore, the presence of the groove 25 also serves to protect the entire sliding surface of the fulcrum portion 4.

前記條溝２５は支点孔１５周辺の摺動面に刻設
したものは、あらゆる種類の鋏に対しても有効で
あるが、特に理美容用の鋏のごとく、支点部周辺

用する場合に顕著な効果を発揮しうる。 The groove 25 carved into the sliding surface around the fulcrum hole 15 is effective for all kinds of scissors, but it is especially effective for cutting into the gap space around the fulcrum, such as hairdressing scissors. This method can be particularly effective when applied to scissors where it is difficult to remove chips.

なお、條溝の深さは間隙空間に滞留する切屑
（理美容用の鋏の場合は毛髪層）の厚さより僅か
に大とするのが好ましい。 The depth of the groove is preferably slightly larger than the thickness of the cuttings (hair layer in the case of hairdressing scissors) remaining in the gap space.

た構成の鋏がある。 As mentioned above, the washer is made from a thin, relatively soft and elastic material such as leather, rubber, or synthetic resin, which is conventionally used in some scissors, and is inserted between the screw that is the fulcrum shaft and the scissor body. There is a pair of scissors that is designed to be attached to a scissor and to achieve smooth opening and closing movement while suppressing rattling caused by a pre-existing gap between the two scissors bodies.

は増大する。 In this embodiment, in addition to the screws and the spring nut, a washer that is exactly the same as the one described above is attached by the same conventional means.By attaching the washer, the smoothness of the opening and closing movement of the scissors is increased. do. In this case, if the elasticity or softness of the washer is too large, the spring elasticity that the spring nut originally has will be added and increased, which will weaken the contact pressure between the two blade surfaces when opening and closing the scissors. Or,
Depending on the force of the fingers during opening and closing operations, the twisting of the scissors body may create a forced gap at the fulcrum, resulting in an inappropriate cutting angle when the two blade surfaces intersect. The washer must be removed or the spring nut must be made with a stronger spring. As mentioned above, by selecting an appropriate spring elastic strength for the mainspring nut, the presence of the washer can reduce the friction between the screw and the fulcrum of the scissor body, resulting in smooth opening and closing movement. The effect of this increases.

次に第６図〜第８図に示す第４の実施例につい

のである。 Some conventional hairdressing scissors have a radial ball bearing attached to the fulcrum shaft in order to reduce friction on the fulcrum shaft and promote smoother opening and closing movements. In many cases, the structure is such that the inward curvature of both blade surfaces is reduced as much as possible to narrow the gap between the two scissor bodies that occurs at the fulcrum, and the opening and closing movement is performed smoothly only in the rotating direction. In the conventional configuration described above, there is no effective means of counteracting the friction that occurs in the axial direction due to the increase or decrease in the gap space that occurs when opening and closing based on the internal curvature of both blade surfaces with respect to the fulcrum shaft. This is because thrust-type bearings cannot be installed on scissor-like structures, so only radial-type bearings, which are effective in the direction of rotation, are used.

動機能を維持できるか否かにかかつている。 As shown in FIGS. 7 and 8, current scissors have a double-edged surface facing the blade surface for cutting across the screw 6, which is the fulcrum shaft, and on the opposite side of the blade surface and the screw 6. The sliding floor portion 17 is slightly protruded on the sliding surface side of the scissors 2 and 3 so as to cause pressure contact. During the opening/closing movement, friction occurs in the scissors in three places: between the screw 6, which is the fulcrum shaft, and the fulcrum holes 15, 15 of the scissors bodies 2, 3, between the cutting blades, and in the sliding floor part 17. . Of these, although the friction at the cutting edge portion and the friction at the sliding bed portion 17 can be reduced to some extent,
Due to its cutting function as scissors, it cannot be completely erased. Friction around the screw 6, which is the fulcrum shaft, is unnecessary for the cutting function of the scissors, and wear around the screw 6 will fatally reduce the function of the scissors. The problem with operating movement is not whether the scissors can be opened and closed smoothly with light force, but rather whether it is possible to reduce wear on the fulcrum shaft and maintain good opening/closing movement function for a longer period of time. It depends on.

印加される力との両力が支点軸部に印加される。 When operating scissors for hairdressing, etc., when performing simple opening/closing movements without special operations with fingers, the amount of force applied to the fulcrum shaft is quite large for general-purpose scissors, etc. It is something. In order to overcome the friction on both blade surfaces and the friction on the sliding bed provided to press the blade surfaces, it is necessary to reduce the force in the rotational direction to the fulcrum shaft and the gap space between the fulcrum. Both forces are applied to the fulcrum shaft portion, including a tensile force applied in the direction in which the tension increases, and a force applied in the axial direction to suppress the tensile force.

ものとなるのである。 With scissors for hairdressing, the force applied to the fulcrum shaft is relatively small when the scissors are opened and closed in a natural state without any twisting motion, but once the force is applied to the fulcrum shaft, Since the friction due to the biased contact of the scissors increases both in the rotating direction and in the axial direction of the fulcrum shaft, the force applied to the fulcrum shaft becomes large.

できる。 When installing the mainspring nut of this example and also installing a ball bearing, there is only the usual minimum gap space between the fulcrums of both scissor bodies, so both the rotational direction and the axial direction are In both directions, both the rotational frictional force and the axial tension force are reduced, producing the effect of making the rotational movement of the scissors smoother. At the same time, since the occurrence of wear in both the rotational direction and the axial direction is reduced, the function of the scissors can be maintained for a longer period of time.
