JP7496672B2 - Scissors for cutting bangs - Google Patents

Description

The present invention relates to a barber or beauty tool, specifically to a technique for effectively cutting bangs.

When cutting hair, for example, as disclosed in JP 2018-19746 A, there are known barber scissors that have been designed to facilitate the cutting of the hair to be cut. When cutting hair, particularly bangs, i.e., hair that extends to the forehead of the person to be cut, with such known barber scissors, from a safety standpoint, the blades are cut along the forehead, i.e., by inserting the blades from the side of the face. In such cases, particularly when the user of the scissors is cutting their own bangs, problems such as "bangs falling out," "bangs escaping," "difficult to use," "tiring hands," and "difficulty in ensuring visibility of the work area" tend to occur.

On the other hand, when cutting bangs, a configuration related to a bangs-cutting auxiliary tool with a cut line indicated is known, as disclosed in, for example, JP 2007-029697 A (Patent Document 2), and it is envisioned that such an auxiliary tool will be combined with the above-mentioned barber scissors to perform the bangs cutting process.

The various techniques related to bangs cutting described above are effective in improving workability to a certain extent; however, since bangs cutting is an area close to the face, there is a demand for the development of techniques to further improve workability, including ensuring workability, visibility, and safety.
JP 2018-19746 A JP 2007-029697 A

The present invention was made in consideration of these points, and aims to provide a technology suitable for improving the workability of bangs cutting treatment.

The above problem is solved by the present invention. In the present invention, a pair of scissors for cutting bangs is provided, which comprises a first and second long scissors body component that are connected to each other around a pivot point. The first and second scissors body components each have a long blade portion and a long handle portion that are formed on either side of the pivot point.

Each of the blade sections is formed as an elongated body extending in the blade length direction, and has opposing metallic blades (also called blades or blade bodies) and a comb section formed on the tip side of the blades for selecting the bangs to be cut. The comb section is preferably made of, for example, resin or rounded metal.

Each of the gripping parts has a finger-extending gripping region formed as an elongated body extending in the longitudinal direction of the gripping part. When the user extends his/her fingers in the longitudinal direction of the gripping part to grip each of the finger-extending gripping regions, the blade parts approach each other in a cross shape toward the forehead of the person to be worked on, whereby the comb part selects bangs and the blades cut the selected bangs.

In the present invention, "bangs" is defined as hair that extends above the forehead of the person to be cut. The "comb" is defined as a member that separates bangs and selects the bangs to be cut. The "state of fingers extended" by the user preferably includes not only a state in which the fingers are fully extended, but also a state in which the fingers are slightly bent. For example, "bending" refers to bending the first and second joints of the fingers at an obtuse angle to create a state that is easy to grasp.

The "subject" of the bangs cutting process preferably includes both the user of the bangs cutting scissors according to the present invention cutting their own bangs and the user cutting the bangs of someone else. Furthermore, "approaching in a crosswise manner" to the user's forehead naturally includes an approach perpendicular or nearly perpendicular to the forehead, but considering that there are various differences in human physical structure, such as differences in race, gender, and age, it also preferably includes an approach that is somewhat inclined.

According to the present invention, the comb portion formed on the tip side of the blade portion can effectively prevent the risk of injury to the forehead or the occurrence of fear when selecting the bangs to be cut. The user of the bangs-cutting scissors can grasp the finger-extended gripping area with the fingers extended in the lengthwise direction of the gripping length and bring the blade portion close to the forehead of the person being treated in a cross shape, so that the user can approach the bangs from the front side of the person being treated and perform pre-treatment (selection process) with the comb portion and cutting process with the blade while reliably ensuring safety and visibility.

In particular, the characteristic configuration allows the user to grasp the scissors using the extended finger gripping area and perform the work by moving in a cross-like manner toward the forehead, which allows the comb and blade sections to be moved left and right (laterally) across the face of the person being treated, allowing the cutting process to be performed while effectively preventing the bangs from scattering or escaping. This significantly improves the ease of use, particularly when the user of the bangs-cutting scissors is cutting their own bangs.

In other words, the bangs-cutting scissors of the present invention provide a working environment that ensures high operability and visibility, thereby not only directly improving operability by making it "easy to use" and "less tiring," but also indirectly improving operability by significantly reducing the fear of the user and the person being worked on when handling a blade, making it "safe" and "peace of mind," thus establishing an ergonomically superior bangs-cutting technique.

The present invention is designed as scissors for cutting bangs, but it can also be suitably applied to tasks that involve approaching the face of the person being worked on in a cross-shaped manner, such as trimming or cutting eyelashes, nose hair, ear hair, and beard.

In a preferred embodiment of the present invention, the finger extension gripping area of each gripping portion is formed to extend in the longitudinal direction of the gripping portion, and each gripping portion can have a ceiling portion that can be placed on the side of the user's fingers in an extended state.

This configuration allows the user to use the bangs-cutting scissors by placing them on the outstretched fingers. In other words, the user can naturally maintain a holding position without having to consciously "hold the bangs-cutting scissors so as not to drop them." As a result, it is possible to create ergonomically superior bangs-cutting scissors that further reduce fatigue during use.

In a preferred embodiment of the present invention, each of the cutting blades may further include a resin cover for covering a rear portion of the blade.
With this configuration, safety can be further improved when working near the forehead of a worker, and fear felt by the user and the worker can be more effectively alleviated.

As a further preferred embodiment of the present invention, the comb portion, the cover and the grip portion may be configured as an integrally molded body made of resin.
By configuring it in this manner, it is possible to improve the efficiency of resin molding production in the manufacturing process of bangs-cutting scissors, and to increase the ingenuity of the design by imparting a sense of unity in appearance to the resin molded part.

In a further preferred embodiment of the present invention, if the vertical direction when the user brings the bangs-cutting scissors close to the face in a cross-like manner toward the forehead is defined as the up-down direction, the extending direction of the blade portion and the extending direction of the grip portion can be formed to cross each other so as to form a predetermined obtuse angle in the downward direction.

With this configuration, when the blade is brought horizontally (or nearly horizontally) from the front toward the subject's forehead, the grip extends at an angle downward from the horizontal, so the user does not need to raise their elbows very high to grasp the grip, and does not need to assume an awkward position to work. This makes it possible to perform a more ergonomic bangs cutting operation.

In a further preferred embodiment of the present invention, the first scissors body component 1 and the second scissors body component are each provided with a magnet that repels each other, and the repulsive force generated between the magnets creates a rotational force acting around the pivot point between the first scissors body component and the second scissors body component in the direction away from each other.

With this configuration, after the user has cut the bangs, the first scissors body component and the second scissors body component can be automatically separated (opened) without any special operation, and the initial position for the next job is automatically set. This allows the user to concentrate on sorting and cutting the bangs with the comb part while minimizing the accumulation of fatigue associated with the job, and further provides a highly ergonomic working environment.

The application of rotational force in the direction of separation between the first and second scissors body components can also be achieved by, for example, placing a tangible elastic element such as a spring or rubber, or a damping element, between the two components. However, in these cases, there is concern that the design of the bangs-cutting scissors may be adversely affected by adding an additional element to the appearance. Furthermore, with these tangible functional components, there is concern that the separation rotational force may decrease due to wear over time. The magnet configuration of the present invention makes it possible to preemptively dispel such concerns.

Furthermore, as a preferred aspect of the present invention, when no external force is applied to the bangs-cutting scissors, the first scissors body component and the second scissors body component can be maintained in an open state by the repulsive force generated between the magnets.
By configuring in this manner, the state in which the first scissors body component and the second scissors body component are open to each other can be set as the initial position, further improving operability for the user.

In a further preferred embodiment, the first scissors body component and the second scissors body component further have caps that cover the blade portions when they are closed to each other, and when the caps are attached, the caps and the pair of gripping portions can form a streamlined, integrated, continuous outer shell.
By configuring it in this manner, it is possible to impart excellent design to the outer casing of the bangs-cutting scissors, which consists of a cap covering each blade portion and a pair of gripping portions, thereby improving the appeal of the bangs-cutting scissors and increasing the satisfaction of their owners.

From the standpoints of size, safety, and external design, it is preferable that the cap be configured to cover each blade portion when the first scissors body component and the second scissors body component are closed to each other.
The cap may be configured to cover not only the blades but also the grips, that is, to cover the entire pair of bangs-cutting scissors. In this case, however, the outer dimensions of the container may become unnecessarily large, but the present invention can eliminate such concerns.

The present invention provides a technique suitable for improving the workability of bangs cutting by using the above-mentioned configurations.

An embodiment of the present invention will be described with reference to Figs. 1 to 5. As shown in Fig. 1, the bangs-cutting scissors 1 according to the embodiment of the present invention are mainly composed of a first scissors body component 11 and a second scissors body component 21 that are connected to each other so as to be rotatable relative to each other about a pivot point 13.

The first scissors body component 11 and the second scissors body component 21 are each formed in an elongated shape and have blades 110, 210 and gripping parts 120, 220 on either side of the pivot fulcrum 13.

The blades 110, 210 are each configured as elongated bodies extending in the blade length direction BL, and have opposing metallic blades 113, 213, resin combs 115, 215 formed on the tip side of the blades 113, 213, and resin covers 117, 217 that cover the backs of the blades 113, 213.

The comb portion 115, 215 is made of resin such as ABS, and is used to select the bangs to be cut. The comb portion 115, 215 may be made of metal and may have rounded tips.
The covers 117, 217 are formed from a resin such as ABS, and by covering the backs of the blades 113, 213, they ensure safety for the user and the person receiving the bangs cutting treatment, as well as providing a sense of psychological security.

The gripping parts 120, 220 are each made of resin, such as ABS, and are formed as elongated bodies extending in the gripping part's longitudinal direction HL, and each have finger-extending gripping areas 123, 223.

The comb parts 115, 215, covers 117, 217, and grip parts 120, 220 are formed as a single piece by resin injection molding when the bangs-cutting scissors 1 are manufactured, and are made of the same material and color scheme to give them a unified appearance.

Magnets 129, 229 are embedded in the opposing surfaces of the finger-extending gripping areas 123, 223. The magnets 129, 229 are made of magnetic material that repel each other (both north poles or both south poles), and are configured to apply a rotational force around the pivot 13 to the gripping parts 120, 220 and the finger-extending gripping areas 123, 223 in directions that move them away from each other, i.e., in directions that open from each other.

On the other hand, the first scissors body component 11 and the second scissors body component 21 are maintained in an open state at the maximum rotation angle relative to each other by the rotation stoppers (not shown) coming into contact with each other. Figure 1 shows the bangs-cutting scissors 1 in an open state at the maximum rotation angle.

As shown in FIG. 2 , which is a side view of the bangs-cutting scissors 1, the blade portions 110, 210 and the grip portions 120, 220 are configured so that the blade length direction BL and the grip portion extension direction HL intersect with each other on the lower side at a predetermined obtuse angle θ (approximately 120° in this embodiment).
The user is configured to grasp the gripping portions 120, 220 with their fingers F (in this embodiment, the first finger F1 (thumb), the second finger F2 (index finger), and the third finger F3 (middle finger)) extended along the gripping portion extension direction H.

As shown in Fig. 3, which is a cross-sectional view taken along line A-A in Fig. 2, the finger-extending gripping area 123, 223 has side portions 125, 225 , ceiling portions 127, 227 , and upper portions 128, 228 for gripping with the surface of the user's fingers when the user extends the fingers. The side portions 125, 225 and ceiling portions 127, 227 are formed as smooth, integral, continuous curved surfaces, and are configured to fit the pads or sides of the user's fingers. The upper portions 128, 228 are portions that are located vertically upward during use, and are portions that are shown in plan in the cross-sectional view in Fig. 3.

3, the user brings the belly FB of the first finger F1 (thumb) into surface contact with the side surface 125 in the finger extension gripping region 123 of the first scissors body constituent part 11, and brings the side FS of the first finger F1 in the extended state into surface contact with the ceiling part 127. Meanwhile, the belly FB of the second finger F2 (index finger) to the third finger F3 (middle finger) in the extended state into surface contact with the side surface 225 in the finger extension gripping region 223 of the second scissors body constituent part 21, and brings the side FS of the second finger F2 to the third finger F3 into surface contact with the ceiling part 227. Preferably, the abdominal part FB and the side part FS of the third finger F3 (middle finger) in the extended state are brought into surface contact with the side part 225 and the ceiling part 227 of the second scissors body part 21, respectively, and the abdominal part or the side part of the second finger F2 (index finger) in the extended state is brought into surface contact with the upper part 128 of the first scissors body part 11 or the upper part 228 of the second scissors body part 21, thereby sandwiching the first scissors body part 11 between the first finger F1 and the second finger F2, or sandwiching the second scissors body part 21 between the third finger F3 and the second finger F2 (see FIG. 4). Note that each finger in FIG. 3 is shown in schematic cross section.

(How to use the bangs cutting scissors 1)
The following describes how the bangs-cutting scissors 1 configured as described above are used. In this embodiment, as an example of use, a case in which a user of the bangs-cutting scissors 1 cuts his or her own bangs, i.e., a case in which the user and the person to be cut are the same person, will be described.

1, 2 and 4, a user U holds the finger-extended gripping regions 123, 223 of the gripping portions 120, 220 of the front hair-cutting scissors 1 with fingers F extended in the longitudinal direction HL of the gripping portion. Specifically, the user holds the finger-extended gripping region 123 of the gripping portion 120 with the thumb F1 extended in the longitudinal direction HL of the gripping portion, and holds the finger-extended gripping region 223 of the gripping portion 220 with the index finger F2 (or middle finger F3) extended (see also FIG. 1 for the configuration of the gripping portion 220). 4, the finger-extended gripping region 223 of the gripping portion 220 is preferably gripped with the middle finger F3 in an extended state, and the index finger F2 is placed on the upper portion 128 of the finger-extended gripping region 123 of the gripping portion 120 or the upper portion 228 of the finger-extended gripping region 223 of the gripping portion 220. In this way, the gripping portion 120 is pinched between the index finger F2 and the thumb F1, or the gripping portion 220 is pinched between the index finger F2 and the middle finger F3. At this time, due to the human body structure, there is some bending at the joints of the fingers, but in this embodiment, such a state is defined as a state in which the fingers F are extended.

The user U brings the bangs-cutting scissors 1 close to the face value FS of his/her forehead in a cross shape and brings the bangs-cutting scissors 1 to his/her bangs H.
Then, the comb portion 115, 215 is used to select and hold the bangs to be cut, and the outstretched fingers H are used to operate the gripping portion 120, 220 in the closing direction, so that the selected bangs H are cut by the blades 113, 213 provided on the cutting portion 110, 210 (see Figures 1 and 2 for the detailed structure of the bangs-cutting scissors 1).

In this case, the user holds the bangs-cutting scissors 1 with extended fingers and approaches the face FS in a crossed manner to perform the operation, thereby moving the comb parts 115, 215 and the blade parts 110, 210 left and right (lateral direction) of the face of the person being worked on, and the cutting process can be performed while effectively preventing the bangs from "scattering" or "running away."

Moreover, as explained in Figure 3, the user can use the bangs-cutting scissors 1 by placing them on the extended fingers F1, F2, or F3, and can naturally maintain a holding position without having to consciously "hold the bangs-cutting scissors 1 so as not to drop it." As a result, fatigue during work can be reduced to a minimum.

In addition, in the bangs-cutting scissors 1 according to this embodiment, the blade length BL and the grip length HL are configured to intersect at an obtuse angle θ downward as described above (see FIG. 2). Therefore, when the blades 112, 210 are brought close to each other in a cross-like manner toward the face value FS, the user does not need to lift the elbow EL very much, which can further reduce fatigue during work.

In this embodiment, by using the bangs-cutting scissors 1 configured as described above, the user U can operate the scissors by extending his/her fingers F in a cross shape toward the face value FS of the person to be cut (i.e., the user himself/herself), thereby providing excellent operability in light of the structure of the human body. In addition, the blades 110, 210 (specifically the tips of the combs 115, 215) approaching the face value FS in a cross shape are easy to see, and good operability can be maintained even when cutting one's own bangs.

In addition, when the bangs-cutting scissors 1 are brought close to the face value FS in a cross-like manner, it is normal for this to cause fear as the blade approaches the face (especially the area close to the eyes). However, in this embodiment, a resin comb portion 115, 215 is provided on the tip side of the blade 113, 213, and the back of the blade 113, 213 is covered with a resin cover 117, 217, so the user can concentrate on the work without worrying or feeling fearful of being injured by sharp metal.

As described above, magnets 129, 229 that repel each other are arranged in the finger-extending gripping areas 123, 223, respectively, so that a rotational force acts on the finger-extending gripping areas 123, 223 around the pivot fulcrum 13 in a direction that moves them apart, i.e., in a direction that opens toward each other. Therefore, when the user releases the application of external force by the fingers after cutting the bangs, the first scissors body component 11 and the second scissors body component 21 are automatically biased to the maximum opening angle and maintained in the open state, and the initial state for the next job is automatically secured without the user having to take the trouble of performing manual operations.

In addition, by using embedded magnets 129, 229 to apply rotational force in the direction separating the first scissors body component 11 and the second scissors body component 21, it is possible to avoid adding unnecessary elements to the appearance of the bangs-cutting scissors 1, and it is also possible to ensure a good means of durability over time.

(Storage, design, portability)
5, the front hair-cutting scissors 1 according to this embodiment further includes a cap 15 that covers the blades 110, 210 when the first scissors body component 11 and the second scissors body component 21 are closed to each other. When the cap 15 is attached to the front hair-cutting scissors 1, the cap 15 and the gripping portions 120, 220 form a streamlined, integral, continuous outer shell. The cap 15 is made of the same material as the gripping portions 120, 220 (ABS resin in this embodiment) and has the same color scheme and tone as the gripping portions 120, 220, to promote unity in design.

With this configuration, the caps that cover the blades 110, 210 and the grips 120, 220 give the outer structure of the bangs-cutting scissors 1 an appearance with excellent design, which can increase the satisfaction of the owner.

When the cap 15 is attached, the first scissors body component 11 and the second scissors body component 12 are closed to each other, and the cap 15 and the gripping parts 120, 220 form a continuous, integral outer shell. This minimizes the risk of the bangs-cutting scissors 1 being damaged by other items when the scissors are carried in a bag or the like. In this respect, the bangs-cutting scissors 1 according to this embodiment are particularly suitable for use as a beauty tool, from the standpoint of functionality as well as excellent design and portability.

The bangs-cutting scissors 1 according to this embodiment provide a technology that is ideal for improving the workability of bangs cutting.
