Description of the new model: [Technical field to which the new model belongs] Improvement of the hair-cutting scissors for beautician and beautician constituted by pivoting, especially \: section and handle) The knife's hand can only open and close the /, M kinds Hold the scissors ^ open the hair clipper to the end. [Prior art] > Scissors for grooming and beauty ' There are two thin-bladed scissors with straight blades, which are straight-to-blade, and -blades. This manual: General scissors are called hair clippers. In addition, there is a knife on the front end half of the knife body: It is called a "knife part" in this manual. male. In addition, if you want to cut a lot of hair by closing it in one operation, you must open the blade of the cutter as far as possible so that the scissors can hold the hair deeply. Therefore, make sure that the hair slides long. When cutting hair with a hair clipper, there are various ways to use the scissors at each stage of the grooming operation. For example, use various types of scissors, such as cutting hair with the top of the blade ... near the center of the blade, or cutting with the blade closer to the base (by the pivot axis). When cutting hair with scissors, 'Usually, it is easier to cut than to cut, so the hair is cut while sliding across the knife peak of the scissors to be closed. For example, as shown in Figure 9, the hair is cut by 1 〇Open. Look like. The two blade bodies 110 and 120 have their center lines (straight lines formed by connecting the pivoted shaft core Q and the tips γ of the blade portions m and 1 2 1) La and Lb to 15 with each other. The angle q. In addition, the opening depth W of the flared blade portions 111 and 121 is shown in the figure. The intersection point q of the center lines La and Lb is, of course, at the position of the pivot axis, and the depth of the opening M267044 degrees W refers to the location p of the intersection point of the knife peak lines A and b. Moreover, if the knife-peak lines A and B are far away from the center lines La ,; Lb, the depth w (that is, the intersection point becomes shallower. Conversely, when the right knife-peak lines A and B are close to the center line and Lb, the depth W becomes In addition, at this time, the shanks 112 and 122 are also spread apart to each other. For example, as shown in FIG. 9, the “contact point Rb of the ring n2a and the other ring 122” is connected to the pole core Q ”. Lines Ma, Mb (hereinafter referred to as
「抵接線Ma、Mb」）張開成15。的角度/3。閉合剪髮剪1〇〇 時，指環112a、122a如_ 10所示彼此抵接，故抵接線Μ&、 Mb亦重疊。又，刀部之中心線La、&亦同樣重疊。 以上之例，係刃部之中心線La、Lb與柄部之抵接線 Ma、Mb以一直線相連的例子。"Abutment lines Ma, Mb") open to 15. Angle of / 3. When the hair clipper 100 is closed, the rings 112a and 122a abut against each other as shown in FIG. 10, so the abutment lines M & and Mb also overlap. Also, the center lines La, & of the knife section also overlap. The above example is an example in which the center lines La and Lb of the blade portion and the abutment lines Ma and Mb of the shank portion are connected in a straight line.

Even in this case, as shown in FIG. 12, the opening angle of the abutment lines Ma and Mb of the handle is the same as the opening angle α of the center line La and Lb. If the handle is opened b . , Then the centerline of the blade is also opened by 15. The point is the same. A person, a clip ν w 丨 small w from the curved concave portion of the inner surface of the cylinder 200 shown in the figure of the garden 1 3. In other words, using scissors, the cylinder 200 in FIG. 13 is used to cut off the part with the curve 201, and the remaining part 203 becomes the blade part and 204 becomes the knife peak. The chain line K in the figure indicates the bus bar κ at the lowest part in the figure. The reason for setting this curved recess on the back of the blade is to make sure that the peaks of the two blades are in contact with each other when the 6 M267044 scissors is opened and closed. That is, the scissors cannot cut hair if the knife peaks do not touch each other. However, if the back surface of the blade body is not dented, the back surfaces may sometimes contact each other. If the back surfaces are in contact with each other, it will prevent the blades from contacting each other. Therefore, the blade back is formed with a curved concave portion 'to prevent the blade backs from contacting each other. This busbar κ is in principle parallel to the knife-peak line 204 as shown in FIG. 13, which is technically correct. Fig. 14 shows the actual blade back 211 of the blade body 210, but the blade peak line 212 is slightly curved as shown in Fig. 14 and is not a straight line. The curve protrudes slightly in the center of the blade portion. The degree of protrusion is due to the straight line Q3 to G5mm connecting the line of the riding line, or more, about 0,.... Therefore, the knife-peak line 212 is approximately a straight line. Therefore, the generatrix κ also becomes a line that is approximately curved. In addition, in this case, the bus bar K is a wire passing through the screw hole 213 for pivoting of the blade body. Also, as shown in FIG. 14, the 'general line' is formed along the knife-peak line 212 and penetrates the back side 214 of the blade body to form a curved concave portion in the shape of a cylindrical inner surface. The curved concave portion of the blade back 211 is generally ground with a disc grinding wheel 300 as shown in FIG. In addition, the disc grindstone 300 was moved with a vertex of 30! "Draw, Hai mother, line K while grinding the curved concave portion of the blade back. At this time, not only the edge portion is ground and passed through the screw At the same time, the edge of the edge of the portion 215 is ground at the same time. Therefore, the peripheral edge 216 of the curved recessed portion of the pivotal portion 215 appears as shown in FIG. 14; 1 4 Tu's connection net; 5; Λ η…, the contact surface 217. The contact Φ 217 is a flat surface that is left after being grinded away from the blade back, Α, and when two blade bodies are pivotally connected by screws, Today, the contact surface 217 becomes the surface that touches each other. The surface that is blackened along the blade peak M267044. In short, the part in contact with the white-blade body in Figure 14 is divided into 218. The parts that are in contact with the other knife peak are blackened. 21 7, 21 8 are all concave parts that can be colored with the other knife body. They are not related to the other. 【New content】 In order to open the ^ hair to the end, you must open the handle. The department was greatly opened, and as a result, page 7 greatly extended the fingers of the hand scissors. However, Rimi Teacher, use the scissors 77 'throughout the day to open and close the scissors repeatedly, so the less the burden of the opening and closing operation, the better. Because &, I hope that even if the opening and closing range of the handle is only: point, the blade can still be cut. Open the scissors in such a way that the depth of the opening is deep. This is because even if the opening and closing of the fingers is small, if the opening of the scissors is opened deeply, it will reduce the burden on the beautician. Therefore, the purpose of this creation is to Provided is a hair-cutting scissors for grooming and beauty. The scissors are for the opening angle of the handle, and the blade is easier to open to the end, and the hair is easy to cut. Hereinafter, the means of this creation will be used in the embodiment described later. (1) This creation is a hairdressing and hair cutting scissors with two blades pivoted. The blade peak line of one blade is pivoted through the top of the blade and the blade. The knife-side end of the trowel (refer to symbol 14 in FIG. 3) (refer to reference 15 in FIG. 3) is retracted to form a line receding further than the end toward the back of the blade body. Generally, hair cutting The cutting knife peak line is slightly curved and roughly approximates a straight line. The straight knife peak line is set to move backward. (2) In addition, the knife peak line of the other blade body is such that the middle part of the knife peak line is M267044 points (refer to the symbol z in FIG. 4) and is formed into a bulge following the aforementioned formula. The shape of the dog; I dog. ^ The square of the knife-back line (3) and the blade back of the two blades are curved concave portions that make the cylinder face the long side of the blade. At this time ,, The recessed part has a square back. The recessed part. That is, the first recessed part is provided with a first recessed part and a second recessed part 7 of the recessed part 7 through a screw hole 1 busbar provided in the pivoted part to be concave. Evening 筮 1 & from the second recess, the mother: =! Cheng, starting at the base end of the knife part from the back side of the first busbar than the first position (above, please refer to ㈣ ... (4 ) In claim 1, a blade body is made of 岌, and is the position where the knife peak line passes, that is, the approximately straight knife peak line A, as shown in FIG. 3, which can be referred to as the general axis, the axis of the axis The wire near the core. X, near the shaft core means that, for example, if the blade width of the pivot part is llmm ', the knife peak line A can also pass through a small circle with a radius of 1 mm or 1.5 mm centered on the shaft center. Alternatively, the knife peak line can pass through a small circle with a radius of less than 10% of the blade width. Because of the composition of (1) or (4) above, the two haircut lines of this creation become lines with different shapes. That is, the first knife peak line is raised to show "the top of the knife body" and "a position receding more than the end of the blade side", but the second "retreating position" can be limited to "pivot axis" (refer to the request Item 2) Also, the pivot shaft is located at a position retracted from the blade-side end. Shape, the other knife-peak line is approximately straight. In this regard, the two peak lines of a general haircut are approximately straight lines. Strictly speaking, even if they are slightly curved, the curved shape is still the same shape, but the curved shapes of the two peak lines of this creation are different. . M267044 According to the above description, the hair clipper of this creation has a deeper opening depth than the scissors without cutting back. That is, if the two knives σ: the knives and the bees of the two knives are followed by the other knives of the opened scissors: open :: I is far away, so the depth of the opened scissors is deep. 2 'Right as described in claim 2,' The line at the base end of the knife-peak line passing through the pivot axis' is shown in FIG. 4, and the knife-peak line is close to middle La. In this regard, the general haircut line shown in Figure 9 or Figure 11. Line B is not backed off as in this creation. In detail, it is connected to the "pivot part: the end in the direction of the direction (Figure 9 of the The symbol 125, the symbol 22 "in the figure u. In addition, compared to the common knife-peak line B, this creative system has a knife-peak line receding to the back 13 side, as shown in Figure 4, even if the center line La, Lb's Zhang 'Angle Phase JS] The intersection of the 77 peak lines is still at the innermost position. That is to say, compared with the hair cutting shears that have not receded, the opening depth of the scissors is deeper. In addition,' Related ( 2) The structure, the middle part of the knife-peak line is left: the-blade body knife-peak line recedes in a raised shape, so when the scissors are combined, the hair can be cut smoothly. The reason is as follows. When the scissors are at the intersection of the knife-peak lines with each other and angle :, called the "crossing angle"), there is a proper angle range. This angle: when the scissors are narrow, the angle of the two blades is too wide. The hair of the person holding the knife body slipped past the knife peak, so the hair fled away and the helmet grasped it, so the hair could not be cut. …, B, on the contrary, 'if the intersection angle is too narrow, the hair does not slide, so: Γ hair cutting', so 'causes a load on the closing operation when cutting, making it difficult M267044 On the other hand, even if the center line is the same Opening angle. If you want to deepen the opening of the scissors, you need to make the intersection angle smaller. Fig. 16 is a conceptual diagram of scissors showing two types of knife peak line setting methods at the same opening angle of a male knife. As shown in Figure 16, the knife-peak lines ((a; [, b) and (A2, b)) of the two types of graphs, even if the opening angles of the center lines La and Lb are the same, the depths / results at the intersections P1 and p2 The parent point P2 has a smaller intersection angle (0 1 > 0 2). This series means that the angle of the intersection of this creative haircut, which can deepen, becomes smaller. In addition, if the angle of intersection is narrow, the problem of difficult cutting due to the pressure cutting of the hair may occur. There are other cases about the angle of the intersection. That is, as shown in (a) and (b) of FIG. 17, generally, the closer the intersection point p of the scissors is to the top of the blade portion, the smaller the parent point angle 0 is. In the case of a scissors with a smaller intersection angle as in this creation, the angle of the intersection of the scissors near the top is smaller. As a result, the angle of the intersection of the top part of the scissors is smaller than the angle range suitable for hair cutting, making it difficult to cut the hair. In other words, "If the angle of the intersection point becomes smaller, the U 2 knife peak lines will gradually approach parallel, and the hair will not slide, and it will be in a state of pressure cutting hair, and the closing resistance will increase," making it difficult to cut the hair. Therefore, it is easy to produce a problem on the tip side of the scissors, which makes it difficult to cut hair due to the narrow intersection angle. In this regard, as shown in FIG. 18, the structure of (2) in this work is to form the other ridge line m to form a convex bulge in such a manner that it follows the ridge line A to retreat. In this way, if another knife peak line B1 forms a curved shape from the base end X to the top end Y, the knife peak line B1 at the top ^ γ has a shape toward the back side 23 of the blade portion 21. Therefore, the scissors of this creation can obtain a large intersection angle even at the same intersection position ρ ′ compared to the intersection point of the blade line B2 which is curved so convexly. Therefore, since the intersection angle is increased, the intersection angle suitable for hair cutting can be ensured, and the hair can be easily cut. Also, because this composition has the structure of (3), Dao Feng can make sure contact with each other necessary for cutting. That is, as shown in FIG. 19, if the second concave portion 18b is formed with the same generatrical line as the first concave portion 18a genera Ka on the negative edge of the blade body i 〇 that is retracted by the blade peak line, the blade peak S is left. The other knife peak (refer to the symbol G in Figure 丨 9) and cannot be contacted. Therefore, in response to the receding knife-peak line A, the curved concave portion (the second concave portion) must also be retracted, and this situation is expressed in the form of the busbar receding. Thereby, the curved concave portion of the blade back can be appropriately arranged as the second concave portion, the contact between the blade peaks becomes better, and as a result, good cutting performance can be obtained. (5) In this creation, the back of a blade body (the opposite side of the blade) is retracted, and the amount of the retreat is equivalent to the amount of retreat of the knife-peak line (see request item 3). Generally speaking, the two blade peaks of the scissors need to be pressed against each other by a force perpendicular to the back of the blade (this force is called "side pressure"). This side pressure is one of the elements to maintain the cutting performance. Without this side pressure, when cutting hair, the knife peaks sometimes _ will be separated (in the vertical direction of the back of the blade), creating gaps between the knife peaks and causing obstacles to cutting performance. Therefore, the blade must have a strength or thickness sufficient to withstand this lateral pressure. In this regard, if the knife-peak line recedes, the width of the blade becomes narrower due to the receding, and the strength of the blade becomes weaker. However, in this creation, the blade is retracted to prevent the blade from narrowing. Therefore, the strength can be maintained and a sufficient side pressure can be obtained. 12 M267044 [Embodiment] Next, the embodiment of this creation will be described based on the drawings. As shown in FIG. 2, the hair clipper of this embodiment is a hairdressing hair clipper formed by pivoting two blade bodies (moving blade 10 and static blade 20), and the blade body has a blade portion 11, 21 和 柄 部 12,22。 21 and the handle 12,22. -In the moving blade 10 of the blade body ', as shown in FIG. 3, the blade peak line A is formed to connect the tip of the blade body and the articulated shaft. Therefore, the knife-peak line A is a line receding further toward the back 13 side than the blade-side end portion 15 which is wider than the blade body of the pivot portion 14. Also, as shown in the outer shape line of the perspective scissors shown in FIG. 4, the knife peak line a is close to substantially overlap the center line La. In addition, there is a segment portion 16 at the connecting portion between the pivot portion 14 and the blade portion η, and the arrangement relationship is that the blade portion 11 itself is retracted toward the back 13 side by about -half the width of the blade body of the pivot portion 14. In other words, the back of the blade body is the amount of retreat equivalent to that of the blade peak line. In addition, the back 13 side also has a special design, and a boundary portion with the pivotal portion 14 is formed into a protruding portion 17 through a concave curved shape. The peak line B of the stationary blade 20, which is another blade body, is formed as a line connecting the top end of the blade body and the vicinity of the blade-side end h of the pivot portion 24 as shown in FIG. 4. Furthermore, the middle part ζ of the knife blade line B is formed in a raised shape so as to follow the moving knife blade line A. The corpus callosum protrudes 2.0 mm from the straight line at both ends of the connecting knife-peak line. Therefore, the one-knife line A has an approximately straight shape, and the other-knife line B has a shape that is more raised than the receding-knife-line A. The two knurls have different shapes. In addition, in the hair-cutting of this embodiment ... the degree of receding of the knife-peak line is large, 13 M267044 If the receding degree is not as large as in this embodiment, the protrusion amount produced by the bulge may be about 1.8mm or 1-6mm. As described above, as the static blade 20 of the other blade body, the blade peak line B of the base end X to the top end γ of the blade body 21 is formed in a convex shape. The knife peak line B is close to the center line Lb in a state close to the base end X, and the knife peak line B is bent to a state where it gradually reverses toward the back 23 as it approaches the top end γ. The shape of the static blade 20, the base end X of the back 23 up to the top end γ, is a concave shape formed along a convex shape substantially along the blade line B. Fig. 5 'shows the back of another blade body 20 after the hair is cut. A curved concave portion 26 is provided on the back of the other blade body 20, and the generatrix K at the lowest position of the concave portion 26 is drawn from the pivotal portion 24 through the screw hole 27 to draw a generaine k parallel to the blade line B. Specifically, the recessed portion% is ground on the disc grindstone 300 shown in FIG. B and moved so that the vertex 301 moves on the generatrix κ. The quasi " Hai busbar K, in fact, gradually moves away from the knife peak line B as it approaches the top end, so it is not the correct parallel. If the busbar κ is separated from the knife peak line in this way ^, when the two knife bodies are pivoted, the closer the knife peak is to the top, γ will become more body-side, and the two Lai Zhi knife peaks will squeeze each other, so the side pressure As a result, good shear performance is obtained. Again, when it is to be close to the pivot portion 24, the grinding wheel 300 that has left the blade back is gradually approached while moving. Therefore, as shown in FIG. Contact with the other-knife contact surface 29. The body is connected to the blade back. Fig. 6 shows the blade back 14 of a blade body 10 M267044 having a first recessed portion 18a and a second recessed portion 18b. The first recessed portion 18a is provided at the pivotal connection portion M centered on the screw hole, and the first bus bar κ is aligned with the longitudinal direction of the blade portion. In addition, the peripheral edge of the i-th concave portion 18a is also semicircular, and a contact φ 19 formed around the peripheral edge can be brought into contact with a contact surface 29 of the other blade body 20. '..., the edge end X' of the four bars in the mouth of the Kouzhou strip, and the second bus bar Kb starts at a position receding from the bus bar & toward the back side. In addition, the second bus Kb starts at a distance D from the knife peak line A which is half the width of the end X; 隹 _ ^ Ί moves forward, gradually extends away from the knife peak line Λ, and finally passes through the back side 13. Therefore, 筮 1 Α and the second concave portion 18b are formed into curved concave portions in accordance with the arrangement of the first bus bar Kb. When the hair clipper 1 is opened, as shown in FIG. 7-, the depth of the hair clipper 1 is assumed to be Wi when the handle 12 is opened 15 °. The depth W2 at the time of opening W1 is the same as that of the conventional hair-cutting shear 100 of FIG. 7 (1)), and the depth Wi peak line A of the hair-cutting haircut 丨 in this embodiment is receded. And increased. & with knife 11 and

Because of the angle of 12 to 22 open hands, even if the opening and closing width of the finger is small,: ' The necessary depth of the dry scissors 1 can reduce the burden of grooming and opening the scissors to six reams. The opening angle of the scissors 1 is set to 5. In the vicinity of the top end, the intersection point θ of the t-blade 1 shown in Fig. 8 (a) uses the angle θ 2 of the intersection point θ 1 of the scissors 1 and the scissors shown in Fig. 8 (b), and the angle becomes θ 1. The angle of the intersection point near the top of the peak will not be too small, which is the same, that is, the knife must have an intersection angle suitable for hair cutting size 15 M267044 •. This is because the blade peak line b of the stationary blade 20 reverses to the back 23 side near the top end γ, that is, the blade peak line β of the stationary blade 20 has a convex relationship. Therefore, even when the hair is cut with the tip of the scissors, the hair can still be properly slipped, and when it is not slipped, the closing resistance is not generated and the hair can be cut smoothly. Also, as described above, although the blade peak line of one blade body moves backward, the curved concave portion of the blade back is provided so that the second bus bar moves backward, so that it can definitely contact the other blade peak and cut hair with certainty.
