Description
[Technical Field]
[0001] The present invention relates to scissors, and more particularly to hairdressing or beauty combing scissors. [Background technology]
[0002] First, we will briefly explain the structure and operation of scissors (cutting scissors) commonly used for barbering and beauty salons. One half of the scissors, which has a moving blade and a thumb ring, is pivotally connected to the other half, which has a stationary blade, a ring finger ring, and a pinky finger hook. By pressing the palm of the thumb against the thumb ring, the moving blade rotates relative to the stationary blade, cutting the hair between them.
[0003] In the field of barbering and beauty, hair design is highly valued. Thinning scissors can be used to create a variety of designs by changing the ends and volume of hair.
[0004] In thinning scissors, if the stationary blade has a comb blade, it is called a normal blade, and the moving blade is called a straight blade. If the moving blade has a comb blade, it is called a reverse blade, and the stationary blade is called a straight blade.
[0005] There is also a type that does not have the concept of a moving blade or a stationary blade, and the thumb can be placed in either ring (Patent Document 1). This type has a high degree of freedom in use. In this application, this type (so-called eyeglass handle) will be described as an example, but the present invention is not limited to this type. [Prior art documents] [Patent documents]
[0006] [Patent Document 1] Patent Publication No. 2004-41268 Summary of the Invention [Problem to be solved by the invention]
[0007] As the times change, a variety of new hairstyles are being proposed, and it is becoming increasingly difficult to apply conventional hair combing scissors to these styles.
[0008] SUMMARY OF THE INVENTION The present invention aims to solve the above problems and to provide scissors that can accommodate a variety of new hairstyles. [Means for solving the problem]
[0009] In order to solve the above problems, the thinning scissors of the present invention are scissors in which a first scissors half having a rod blade and a second scissors half having a comb blade are rotatably connected by a support part. The comb blade is formed by a plurality of comb teeth and spaces alternately arranged in the longitudinal direction of the scissors. A fine manipulation part is formed on the tip side of the comb blade. The tip width of the first scissors half is less than 3.3 mm, and the radius of the curve formed by the outer edge of the range of the first scissors half corresponding to the fine manipulation part is 350 mm or less. The tip width of the second scissors half is less than 4.5 mm, and the radius of the curve formed by the outer edge of the range of the second scissors half corresponding to the fine manipulation part is 350 mm or less.
[0010] The micro-operation unit allows for fine manipulation. The unique shape also allows for the installation of a micro-operation unit. The unique shape allows for the adjustment of minute irregularities on the head. This allows for a variety of new hairstyles.
[0011] In the above invention, preferably, the comb tooth width in the fine manipulation portion is 0.8 to 1.5 times the space width.
[0012] In the above invention, preferably, the fine operation section has a clearance ratio of less than 15%.
[0013] This makes the comb teeth of the fine manipulation portion suitable for fine manipulation.
[0014] In the above invention, the comb width in the area other than the fine manipulation section is preferably 1.5 to 2.2 times the space width.
[0015] In the above invention, the clearance rate in areas other than the fine operation section is preferably 20% or more.
[0016] This ensures ease of operation for the comb teeth other than the fine manipulation portion.
[0017] The fine manipulation portion is formed on the tip side of the comb blade, in a range of 5 to 25% of the length from the tip to the pivot portion.
[0018] By providing the fine manipulation portion in an appropriate range on the tip side of the comb blade, insufficient force transmission does not become a problem even with a distinctive blade tip shape.
[0019] In the above invention, preferably, the comb teeth of the fine manipulation portion are flat.
[0020] In the above invention, preferably, the comb teeth of the fine manipulation portion have cutting edges.
[0021] This allows hair to be cut from both sides of the blade. Sharpness is particularly important in the fine manipulation section.
[0022] To solve the above problem, the present invention provides a method of using the above-mentioned thinning scissors. A gradation is temporarily formed in a section of hair cut with clippers or cutting scissors using the comb teeth other than the fine manipulation unit. The comb teeth of the fine manipulation unit are used to cut the section of hair within the gradation that corresponds to the concave shape of the head.
[0023] This allows for the maintenance of workability through conventional methods, while allowing for fine adjustments to be made to defective areas and achieving subtle adjustments to the gradation. [Effects of the Invention]
[0024] The scissors of the present invention can accommodate a variety of new hairstyles. [Brief explanation of the drawings]

[0026] ~Basic configuration~ Fig. 1 shows scissors according to this embodiment. Scissor half 1 and scissors half 2 are rotatably connected by a pivot support 3. In this embodiment, an example will be described in which there is no concept of a moving blade or a stationary blade, and the thumb can be placed in either ring. Fig. 2 is a detailed view of scissors half 1 and scissors half 2.
[0027] The blade 11 is connected to the ring 13 via the handle 12, forming the scissors half 1. A little finger hook 14 is extended from the ring 13. The comb blade 21 is connected to the ring 23 via the handle 22, forming the scissors half 2. A little finger hook 24 is extended from the ring 23.
[0028] 3 is a schematic diagram of the comb blade 21. The comb blade 21 is formed by arranging a plurality of comb teeth 41, 51 and spaces 42, 52 alternately in the longitudinal direction of the scissors.
[0029] ~Characteristic composition 1~ As one characteristic configuration of this embodiment, a fine manipulation section 40 is formed on the tip side of the comb blade 21. For example, it is formed in a range of 5-25% of the length from the tip to the axial support part. Preferably, it is formed in a range of 10-20%. In the illustrated example, the fine manipulation section 40 is formed from the tip comb tooth to the fourth comb tooth, and this range is about 13% of the length from the tip to the axial support part. A part other than the fine manipulation section 50 is formed on the axial support part side of the comb blade 21.
[0030] 4 shows a schematic configuration relating to the comb tooth width and space width. The width of the comb teeth 41 in the fine-manipulation unit 40 is narrower than the width of the comb teeth 51 in the non-fine-manipulation unit 50. The width of the space 42 between the comb teeth 41, 41 in the fine-manipulation unit 40 is wider than or approximately the same as the width of the space 52 between the comb teeth 51, 51 in the non-fine-manipulation unit 50.
[0031] For example, the width of the comb teeth 41 in the fine manipulation unit 40 is 0.8 to 1.5 times the width of the space 42. It is preferably 0.9 to 1.3 times. In the illustrated example, it is about 1.1 times on average.
[0032] The width of the comb teeth 51 in the area other than the fine manipulation area 50 is 1.5 to 2.2 times the width of the space 52. It is preferably 1.7 to 2.0 times. In the illustrated example, it is about 1.8 times on average.
[0033] This makes it possible to achieve a thinning rate of less than 15% in the fine operation section 40, and a thinning rate of 20% or more in the sections other than the fine operation section 50. In the illustrated example, a thinning rate of 10% or less in the fine operation section 40 and a thinning rate of approximately 25% in the sections other than the fine operation section 50 are assumed. The thinning rate is the proportion of hair that is cut at one time. The higher the thinning rate, the more hair is cut, and the lower the thinning rate, the less hair is cut. In other words, the fine operation section 40 is suitable for fine work. Meanwhile, the sections other than the fine operation section 50 maintain the same operability as the conventional example (see Figures 7 to 9).
[0034] ~Characteristic composition 2~ Fig. 5 is a schematic diagram of the cutting edge shape in this embodiment. Fig. 6 is a schematic diagram of the outer edge of the cutting edge in this embodiment. Note that the numerical values shown in Fig. 6 are estimated values from the drawing and are for reference only. This embodiment has a cutting edge shape as another characteristic feature.
[0035] The width of the tip of the scissors half 1 is less than 3.3 mm. In the illustrated example, it is about 3.0 mm. The radius of the curve formed by the outer edge of the area corresponding to the fine manipulation unit 40 of the scissors half 1 (the rod blades do not have comb teeth) is 350 mm or less. More preferably, it is 300 mm or less.
[0036] The width of the tip of the scissors half 2 is less than 4.5 mm. In the illustrated example, it is about 3.9 mm. The radius of the curve formed by the outer edge of the area corresponding to the fine manipulation portion 40 of the scissors half 2 is 350 mm or less. More preferably, it is 300 mm or less.
[0037] That is, the cutting edge shape of this embodiment tapers sharply toward the tip, and the tip is relatively sharp. Note that the smaller the curve radius, the greater the curvature.
[0038] The cutting edge shape of this embodiment will be further explained while comparing it with the cutting edge shapes of the conventional example and the reference example.
[0039] Fig. 7 shows scissors according to a conventional example. Fig. 8 shows a schematic diagram of the cutting edge shape in the conventional example. Fig. 9 shows a schematic diagram of the cutting edge outer edge in the conventional example. The conventional example is a commonly used thinning scissors. The basic configuration is the same as that of this embodiment.
[0040] Although the conventional example does not have a fine manipulation section, for the sake of comparison with this embodiment, we will assume that the section from the tip of the comb tooth to the fourth comb tooth corresponds to the fine manipulation section. In the example shown in the figure, the comb tooth width is an average of 2.5 times the space width.
[0041] In the illustrated example, the width of the tip of the scissors half (rod blade) is about 4.0 mm. The radius of the curve formed by the outer edge of the range corresponding to the fine manipulation portion of the scissors half (rod blade) exceeds 350 mm.
[0042] In the illustrated example, the width of the tip of the scissors half (comb blades) is about 7.2 mm. The radius of the curve formed by the outer edge of the range corresponding to the fine manipulation portion of the scissors half (comb blades) exceeds 350 mm.
[0043] The larger the radius of the curve, the smaller the curvature. In other words, the cutting edge shape of the conventional example is relatively thick at the tip while remaining relatively parallel. In general, in thinning scissors, it is difficult to transmit force to the comb teeth, so the blade width of both the rod blades and the comb blades tends to be thick to make it easier to transmit force.
[0044] Fig. 10 shows scissors according to a reference example. Fig. 11 shows a schematic diagram of the cutting edge shape in the reference example. Fig. 12 shows a schematic diagram of the cutting edge outer edge in the reference example. The reference example is a pair of scissors (cutting scissors) commonly used for barbering or beauty treatment.
[0045] In cutting scissors, the moving blade is connected to the thumb ring via the handle, forming one scissors half. A hitting point is extended from the thumb ring. The stationary blade is connected to the ring finger ring via the handle, forming the other scissors half. A little finger hook is extended from the ring finger ring. The first scissors half and the other scissors half are rotatably connected by a pivot support. By pressing the pad of the thumb against the thumb ring, the moving blade rotates relative to the stationary blade, cutting the hair between the moving and moving blades.
[0046] The scissors according to the reference example do not have comb blades and therefore do not have a fine manipulation unit. For comparison with this embodiment, the fine manipulation unit is defined as approximately 14% of the length from the tip to the pivot support.
[0047] In the illustrated example, the width of the tip of the scissors half (moving blade) is approximately 2.1 mm. The radius of the curve formed by the outer edge of the range corresponding to the fine manipulation portion of the scissors half (moving blade) is 300 mm or less.
[0048] In the illustrated example, the width of the tip of the scissors half (static blade) is approximately 2.3 mm. The radius of the curve formed by the outer edge of the range corresponding to the fine manipulation portion of the scissors half (static blade) is 300 mm or less.
[0049] When comparing the cutting edge shape of this embodiment with that of the conventional example and the reference example, the shape of this embodiment is more similar to the shape of the reference example (without comb teeth) than to the shape of the conventional example (with comb teeth). Furthermore, when comparing this embodiment with the reference example, this embodiment is characterized by having a slightly thicker cutting edge so that comb teeth are also provided on the cutting edge.
[0050] ~Ancillary Configuration~ FIG. 13 shows a comparison between the conventional example (A) and this embodiment (B) in terms of the details of the comb teeth.
[0051] In the conventional comb, grooves are formed in the blade width direction. Also, the comb teeth do not have cutting edges. As a result, hair is held down through the grooves in the comb teeth, and the hair is cut by the cutting edges on the rod blades.
[0052] The comb teeth in this embodiment are flat and do not have grooves. The comb teeth have blade surfaces at the tops. This allows hair to be cut by both the blade surfaces of the comb teeth and the blade surfaces of the rod blades.
[0053] In this embodiment, it is preferable that the comb teeth of the fine manipulation unit 40 have the above-mentioned additional configuration. The comb blades of the fine manipulation unit are particularly required to be sharp.
[0054] The comb teeth of the other part of the fine manipulation section 50 may be the same as those of the conventional example. Also, the comb teeth of the other part of the fine manipulation section 50 may be the aforementioned additional configuration.
[0055] ~Usage example~ An example of use of this embodiment will be described.
[0056] In the fields of barbering and beauty, hair design is considered important. Thinning scissors can be used to create a variety of designs by varying the ends and volume of hair. As times change, a variety of new hairstyles are being proposed. For example, a hair design known as a fade cut is popular among male athletes.
[0057] In a traditional updo, the hair is roughly uniform, about 3 to 15 mm, whereas in a fade cut, the hair is about 0 mm at the bottom and gets darker as it goes to the top, creating a gradation. The subtleties of the gradation affect the design. However, traditional updos do not require the same subtleties as fade cuts.
[0058] Here's how to create a fade cut: First, use clippers or scissors (example) to roughly align the cut area to the correct length.
[0059] 14 shows an example of using this embodiment. At this location, hair is combed using the comb blades of the fine manipulation unit 50 of this embodiment to form a gradation. Conventional combing scissors may also be used.
[0060] Figure 15 shows an example of a problem that occurs during hair cutting. If the shape of the head is close to a sphere, it is possible to create a gradation as desired using clippers or cutting scissors and thinning shears. However, each individual head shape has subtle irregularities. Therefore, even if the hair is cut to the appropriate length, the hair in the concave areas, for example, will be longer than the surrounding areas (see Figure 17), making it appear darker than the surrounding areas. As a result, it is not possible to create a beautiful gradation line.
[0061] 16 and 17 show examples of using this embodiment. At that location, the comb blade of the fine manipulation unit 40 of this embodiment is used to cut the area that appears darker than the surrounding area.
[0062] Figure 18 shows a good example of cutting. By slightly cutting the area that looks darker than the surrounding area to make it lighter, a beautiful gradation line is created.
[0063] Although the application of this embodiment to a fade cut has been described as an example of use, it is also suitable for cuts that require fine manipulation.
[0064] ~Effects~ In this embodiment, a fine manipulation unit 40 (characteristic configuration 1) is formed on the tip side of the comb blade, and fine manipulation is possible via the fine manipulation unit 40. On the other hand, the fine manipulation unit 40 is specialized for fine manipulation. With a thinning rate of the fine manipulation unit 40 of less than 15%, the amount of hair cut is small, and no problems related to insufficient force transmission occur.
[0065] As a result, in this embodiment, a characteristic blade tip shape (characteristic configuration 2) can be achieved. The fine operation portion 40 can be formed in the characteristic blade tip shape.
[0066] Furthermore, the unique blade shape allows the scissors to be positioned to accommodate the subtle unevenness of the head (see Figure 17).However, with conventional blade shapes, it is difficult to perform fine manipulation to accommodate the subtle unevenness of the head.
[0067] The parts other than the fine operation unit 50 are similar to those of the conventional example, and can be used in the same manner as the conventional example. In other words, this embodiment allows both normal operation and fine operation. By using the fine operation unit 40 and the parts other than the fine operation unit 50 appropriately, fine operation and operability can both be achieved.
[0068] As described above, in this embodiment, the interaction between characteristic configuration 1 and characteristic configuration 2 produces a synergistic effect, which cannot be predicted from the conventional example. [Explanation of symbols]
