Description

Technical Field

[0001] The present disclosure relates to a hair cutter for a delicate zone.

Background Art

[0002] Conventionally, in Patent Document 1, a hair cutter has been proposed that includes a pair of blade holders on both sides in the extending direction of a rod-shaped elongated portion. In this hair cutter, the blade members of each of the pair of blade holders are arranged within a comb-shaped portion, and the hair guided into the slit of the comb-shaped portion is cut by the blade members. Since the blade members are arranged within the comb-shaped portion, when cutting hair with the blade member provided on one blade holder, the user's hand can be prevented from directly touching the blade member provided on the other blade holder. As a result, it is a user-friendly hair cutter that does not require covering the other blade holder with a cap or the like when using one blade holder.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the above hair cutter, since it has a structure in which a pair of blade holders are arranged at both ends in the extending direction of the elongated portion, two types of blade members cannot be used unless the hair cutter is held upside down. Further, since the cutting directions of the two types of blade members are in the same direction, there is a possibility of making a shaving mistake.

[0005] An object of the present disclosure is to provide a hair cutter for a delicate zone (hereinafter simply referred to as a hair cutter) that can use two types of blade members without turning it upside down. Another object is to provide a hair cutter that can also prevent shaving mistakes.

Means for Solving the Problem

[0006] To achieve the above object, the invention according to claim 1 is a hair cutter for a delicate zone, comprising a body portion (10) composed of a rod-shaped member having a central axis (L) along one direction and having a tip portion (11) and a rear end portion (12) opposite to the tip portion; a first blade portion (20) including a first blade body (26) disposed on the tip portion side of the body portion and having a first blade edge (26a) disposed along a direction orthogonal to the central axis, and a first comb structure (27) having a first comb tooth (25) surrounding the first blade body, for cutting hair (101) passing through the first comb tooth with the first blade body; a second blade portion (30) disposed inside the body portion on the rear end portion side rather than the tip portion, including a second blade body (33) having a second blade edge (33a) disposed along the central axis and a second comb structure (34) formed with a second comb tooth (31) surrounding the second blade body, for cutting hair passing through the second comb tooth with the second blade body; and a gripping portion (13) configured on the rear end portion side of the body portion with respect to the second blade portion. The first blade portion performs hair cutting with the first blade body by being moved in a first cutting direction (D1) intersecting the central axis, and the second blade portion performs hair cutting with the second blade body by being moved in a second cutting direction (D2) which is a direction intersecting the central axis and different from the first cutting direction.

[0007] Thus, the first blade portion and the second blade portion are arranged on the same side with respect to the gripping portion. Therefore, when using the first blade portion and the second blade portion, hair cutting can be performed using the first blade portion and the second blade portion without changing the way of holding the gripping portion in the vertically inverted direction. Further, since the first cutting direction for hair cutting with the first blade portion and the second cutting direction for hair cutting with the second blade portion are different directions, the hair cutter is moved in different directions for each part where hair cutting is performed. Therefore, shaving mistakes can be prevented.

[0008] In the invention according to claim 2, for the first blade body (26), it is disposed on the tip end portion (11) side of the body portion (10), and a pair of leg portions (21) erected on both sides sandwiching the central axis at the tip end portion of the body portion, and a first blade body (26) bridged to both tip ends of the pair of leg portions and a first comb structure (27) having first comb teeth (25) surrounding the first blade body are included, and the hair (101) passing through the first comb teeth is configured to be cut by the first blade body. And the first blade portion is moved in a first cutting direction (D1) that intersects the direction in which the pair of leg portions are arranged and also intersects the central axis, so as to perform hair cutting by the first blade body, and the second blade portion is moved in a second cutting direction (D2) that intersects the central axis and is different from the first cutting direction, so as to perform hair cutting by the second blade body.

[0009] In this way, the structure can be such that the first comb structure is bridged to a pair of leg portions erected at the tip end portion of the body portion. Even in such a configuration, since the first blade portion and the second blade portion are arranged on the same side with respect to the gripping portion, hair cutting can be performed using the first blade portion and the second blade portion without having to change the way of holding the gripping portion in the vertically reversed direction. Also, since the first cutting direction and the second cutting direction are different directions, shaving mistakes can be prevented.

[0010] In the invention according to claim 3, between the first comb structure and the body portion, a window portion (28) surrounded by the pair of leg portions, the first comb structure, and the tip end portion of the body portion is formed. Therefore, when performing hair cutting with the first blade portion, it is possible to easily check the place where the hair cutting is performed.

[0011] In the invention according to claim 4, the pair of leg portions have recesses (21a) recessed in a direction opposite to the direction in which the tooth tips of the first blade body are directed, between the tips of the pair of leg portions where the first comb structure is disposed and the tip end portion of the body portion. Therefore, at the time of hair cutting, only the first comb structure contacts the skin, making it difficult for the leg portions to contact, and it becomes possible to facilitate hair cutting.

[0012] The invention according to claim 5 is a hair cutter for a delicate zone, comprising a body portion (10) composed of a rod-shaped member having a central axis (L) along one direction and having a tip portion (11) and a rear end portion (12) on the side opposite to the tip portion, a first blade body (26) having a first blade edge (26a) arranged along a direction orthogonal to the central axis on the tip portion side of the body portion, and a first comb structure (27) having first comb teeth (25) surrounding the first blade body, a first blade portion (20) for cutting the hair (101) passing through the first comb teeth short with the first blade body, a second blade body (33) arranged in the body portion on the rear end portion side rather than the tip portion and having a second blade edge (33a) arranged along the central axis, and a second comb structure (34) in which second comb teeth (31) surrounding the second blade body are formed, a second blade portion (30) for cutting the hair passing through the second comb teeth so as to align it longer than the first blade portion with the second blade body, and a gripping portion (13) formed on the rear end portion side rather than the second blade portion in the body portion.

[0013] Thus, by providing two types of razors, namely the first blade portion and the second blade portion, the hair can be cut short by the first blade portion and cut so as to be aligned longer than the first blade portion by the second blade portion. Therefore, it becomes possible to perform haircuts of different lengths with the first blade portion and the second blade portion. Accordingly, it is possible to adjust the hair to different lengths according to one's preference by using the appropriate one of the first blade portion and the second blade portion according to the part where the haircut is desired. Also, even in such a configuration, since the first blade portion and the second blade portion are arranged on the same side with respect to the gripping portion, it is possible to perform a haircut using the first blade portion and the second blade portion without changing the way of holding the gripping portion in the vertically inverted direction.

[0014] For example, as in the invention according to claim 6, by making the second distance from the blade edge of the second blade body to the tooth tip of the second comb teeth in the second blade portion longer than the first distance from the blade edge of the first blade body to the tooth tip of the first comb teeth in the first blade portion, it is possible to perform haircuts of different lengths with the first blade portion and the second blade portion.

[0015] In the invention according to claim 7, when viewed from the direction along the central axis, in the radial direction centered on the central axis, all of the first blade portions are within the dimensions of the gripping portion. Therefore, the size of the first blade portion can be suppressed, and the first blade portion can be prevented from getting in the way when performing a haircut in the delicate zone.

[0016] In the invention according to claim 8, in the portion of the body portion where the second blade portion is disposed, a finger rest portion in which the body portion is partially recessed is provided on the side opposite to the side toward which the cutting edge of the second blade body is directed. As a result, the ease of gripping the gripping portion when using the second blade portion can be improved, and a stable haircut can be performed when using the second blade portion.

[0017] In the invention according to claim 9, the interval between the teeth in the second comb teeth is wider than the interval between the teeth in the first comb teeth. In this way, for the first blade portion that constitutes the T-shaped razor, the hair can be made to enter and cut in a direction close to perpendicular to the first cutting edge by narrowing the interval between the first comb teeth. Further, for the second blade portion that constitutes the L-shaped razor, by widening the interval between the second comb teeth, the hair can be cut so that it can move not only in a component perpendicular to the second cutting edge but also in a component along the direction of the second cutting edge.

[0018] In the invention according to claim 10, the gripping portion of the body portion is formed in a cylindrical shape with an open rear end portion. As a result, the body portion can be configured with a simple structure of a cylindrical shape with an open rear end portion. Further, with such a simple structure, a meat theft can be configured, so that when the body portion is configured by resin molding or the like, deformation of the body portion due to heat shrinkage or the like can be suppressed, and the body portion can be formed into a stable shape. Note that the reference numerals in parentheses attached to each component or the like indicate an example of the correspondence relationship between the component or the like and the specific components or the like described in the embodiments described later.

Embodiments for Carrying Out the Invention

[0020] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In addition, including other embodiments described below, parts that are the same or equivalent to each other among the embodiments will be described with the same reference numerals.

[0021] (First Embodiment) Hereinafter, the hair cutter 1 according to the first embodiment of the present disclosure will be described with reference to Figs. 1 to 13.

[0022] 〔Configuration of Hair Cutter 1〕 The hair clipper 1 shown in FIGS. 1 to 7 is suitable for haircuts in delicate areas such as the VIO zone. The hair clipper 1 combines two types of razors and enables the use of the two types of razors without the need to change the holding position in the vertical direction, allowing for a comfortable haircut in the VIO zone. In the case of this embodiment, the two types of razors are a T-shaped razor and an L-shaped razor, and since both the T-shaped razor and the L-shaped razor can be used with a single hair clipper 1, it is possible to achieve a haircut that makes use of the respective characteristics. Note that the V zone indicates the area below the pubis, which is called the bikini line, the I zone indicates the area from around the genitals to the anus, and the O zone indicates the area around the anus.

[0023] In addition, the X-axis, Y-axis, and Z-axis are shown in the drawings attached to this specification. As shown in FIG. 1, when the hair clipper 1 is viewed from the front, the vertical direction is called the X-axis, the left-right direction of the hair clipper 1 orthogonal to the X-axis is called the Y-axis, and the thickness direction of the hair clipper 1 orthogonal to the X-axis and Y-axis is called the Z-axis. Also, in FIG. 1, the upper side and the lower side along the X-axis direction are called the upper side and the lower side of the hair clipper 1, respectively, and the right side and the left side along the Y-axis are called the right side and the left side of the hair clipper 1, respectively.

[0024] As shown in FIGS. 1 to 7, the hair clipper 1 is configured to have a body portion 10, a first blade portion 20, and a second blade portion 30.

[0025] 〔Configuration of the body portion 10〕 The body portion 10 is a rod-shaped member having a longitudinal direction in one direction, with a tip portion 11 and a rear end portion 12 on the opposite side thereof. The first blade portion 20 is attached to the tip portion 11 of the body portion 10, the rear end portion 12 side serves as a grip portion 13, and the second blade portion 30 is built into the space between the tip portion 11 and the grip portion 13.

[0026] The body part 10 is made of, for example, resin. The body part 10 has a central axis L along the longitudinal direction, and the overall shape is a columnar shape, an elliptical columnar shape, an oblong columnar shape, or a polygonal columnar shape with a cross-sectional shape that is circular, elliptical, oblong, or a polygon with rounded corners, with the central axis L as the normal direction. In the present embodiment, as shown in FIG. 6, the body part 10 is an elliptical columnar shape with an elliptical cross-section. Also, the dimensions in each direction in the radial direction centered on the central axis L in the body part 10 are the same along the central axis L in the gripping part 13, and the part of the tip part 11 that leads to the second blade part 30 is also made to have substantially the same dimensions as the gripping part 13.

[0027] The body part 10 may be solid with a filled interior, but in the present embodiment, as shown in FIGS. 6 and 7, in the gripping part 13, it has a cylindrical shape with a hollow part 14 opening at the rear end part 12. In this way, material savings can be achieved by forming the hollow part 14, etc., and molding defects due to thermal shrinkage when forming the body part 10 by resin molding can be suppressed.

[0028] Note that the body part 10 can also have material savings other than the hollow part 14. Here, as shown in FIG. 2, a recess 13a is also formed as a material saving at a position adjacent to the second blade part 30 in the gripping part 13. As shown in FIG. 7, inside the gripping part 13, the tip of the hollow part 14 is hemispherical. The recess 13a is located between the boundary position with the second blade part 30 in the gripping part 13 and the tip of the hollow part 14, and is formed in a triangular shape on both the left and right sides with the central axis L interposed therebetween.

[0029] On the tip 11 side of the holding part 13 in the body part 10, that is, the position where the second blade part 30 is built in, has the shape in which the second comb teeth 31 described later in the second blade part 30 are formed. Specifically, as shown in FIG. 1, taking the right part of the body part 10 as the base part 15, the second comb teeth 31 are formed so as to protrude in the Y-axis direction from the base part 15. At the position where the second blade part 30 is built in, the body part 10 is recessed from the left side to the right side of the hair cutter 1, and a plurality of slits 16 arranged at equal intervals along the central axis L are formed. A plurality of the second comb teeth 31 are constituted by the protruding parts 17 left between the respective slits 16 in the body part 10.

[0030] The base part 15 supports the second comb teeth 31 and extends along the central axis L to connect the tip 11 and the holding part 13. The base part 15 has dimensions that can withstand the load when using the first blade part 20 and the second blade part 30.

[0031] Also, an opening 18 is formed on the right side surface of the part that becomes the base part 15 in the body part 10, that is, the side surface opposite to the second comb teeth 31, as shown in FIG. 7. Components of the second blade part 30 shown in FIG. 8 are fitted into this opening 18, and the opening 18 is covered and tightened by a holder 32 described later among the components. The bottom part 32a of the holder 32 that is exposed to the outside on the right side of the body part 10 serves as a part of the body part 10. And the bottom part 32a is recessed in an arc shape, and a finger rest part 19 in which the body part 10 is partially recessed is constituted by this recessed part. The finger rest part 19 becomes a part where the user's finger is placed when performing a haircut using the second blade part 30.

[0032] The tip portion 11 of the body portion 10 is located on the side opposite to the gripping portion 13 across the portion of the body portion 10 where the second blade portion 30 is built in, and is the portion where the first blade portion 20 is provided. By providing the first blade portion 20 at the tip portion 11 in this way, the hair cutter 1 has a structure in which the first blade portion 20, the second blade portion 30, and the gripping portion 13 are arranged in order from top to bottom. Note that the shape of the tip portion 11 is arbitrary, but it is arc-shaped between a pair of leg portions 21 of the first blade portion 20 described later. Between the tip position that is arc-shaped in the tip portion 11 and the second blade portion 30, recesses 11a and 11b that constitute meat theft are formed. The recess 11a is formed at a location closer to the second blade portion 30 in the tip portion 11 and at a location corresponding to the recess 13a provided on the gripping portion 13 side, and has a triangularly recessed shape. The recess 11b has a semi-circularly recessed shape between the recess 11a and the arc-shaped tip position of the tip portion 11.

[0033] Note that even in the portion where the second blade portion 30 is built in, in the portion of the second comb teeth 31, the dimensions in each radial direction centered on the central axis L are aligned with the gripping portion 13. Also, at the base portion 15, the portion that is the finger-attaching portion 19 has a smaller radial dimension than the gripping portion 13, but the dimensions in each radial direction are aligned with the gripping portion 13 in the portions other than the finger-attaching portion 19.

[0034] 〔Configuration of the first blade portion 20〕 The first blade portion 20 is attached to the tip portion 11 of the body portion 10 and constitutes a T-shaped razor. The first blade portion 20 performs hair cutting with the first cutting direction D1 being a direction that intersects the central axis L and goes from the far side of the paper surface of FIG. 1 to the near side of the paper surface, and the left direction of the paper surface of FIG. 3. In the hair cutter 1 of the present embodiment, actually, as shown in FIG. 3, the first cutting direction D1 intersects the central axis L but is not perpendicular, but is a direction slightly inclined with respect to the Z-axis direction, but will be described as a direction along the Z-axis direction.

[0035] Specifically, the first blade part 20 includes a pair of leg parts 21, and each part such as the support part 22 is attached to the body part 10 via this pair of leg parts 21. The pair of leg parts 21 and the support part 22 may be separate from the body part 10, but in the case of this embodiment, by being integrally formed with the body part 10, the rigidity of the pair of leg parts 21 is enhanced.

[0036] The pair of leg parts 21 are erected on both sides of the center axis L at the tip part 11, respectively, sandwiching the center axis L. The direction that intersects the direction in which the pair of leg parts 21 are arranged and also intersects the center axis L1 is the first cutting direction D1. The pair of leg parts 21 are arranged offset to the side opposite to the Z-axis direction from the center axis L in FIG. 1, that is, to the right side of the paper surface in FIG. 3. And between the tips of the pair of leg parts 21 and the tip part 11 of the body part 10, a recess 21a recessed in the direction opposite to the first cutting direction D1 is formed. The recess 21a is formed in a shape that gradually curves and recesses from the tip of each leg part 21 and the tip part 11 of the body part 10 toward the central position of the leg part 21. By providing this recess 21a, it becomes difficult for the leg part 21 to contact the skin during a haircut, and it becomes easier to cut hair.

[0037] As shown in FIG. 1, when the hair cutter 1 is viewed from the front, the pair of leg parts 21 are arranged parallel to the center axis L at a place equidistant from the center axis L. And as shown in FIG. 5, when viewed from the direction along the center axis L, in the radial direction centered on the center axis L, all of the first blade part 20 including the pair of leg parts 21 is made to fit within the dimensions of the gripping part 13.

[0038] The support part 22 is formed so as to bridge both tips of the pair of leg parts 21, and in this embodiment, it is integrally formed with the pair of leg parts 21. And a cover part 23 is arranged so as to cover the upper part of the support part 22.

[0039] The cover part 23 is attached to the support part 22. By forming a plurality of groove parts 24 together with the support part 22, the first comb teeth 25 are constituted, and it is a part for fixing the first blade body 26 between it and the support part 22. The support part 22 and the cover part 23 that constitute the groove part 24 and the first comb teeth 25, and the first blade body 26 disposed therebetween constitute the first comb structure 27.

[0040] The cover part 23 is configured separately from the support part 22, but is formed of, for example, the same material and the same color as the support part 22. Thereby, the appearance unity between the support part 22 and the cover part 23 is maintained. As shown in FIGS. 2 and 7, on one surface of the cover part 23 on the support part 22 side, columnar engagement protrusions 23a are provided at two locations arranged in the Y-axis direction, and the cover part 23 is attached to the support part 22 by fitting the engagement protrusions 23a into through holes 22a formed in the support part 22. As shown in FIG. 9, the first blade body 26 is in a substantially rectangular plate shape, and a haircut is performed with one side of the long side as the first blade tip 26a. An oval long hole 26b having the Y-axis direction as the major axis is formed inside the first blade body 26, and the cover part 23 is attached to the support part 22 by inserting the engagement protrusion 23a of the cover part 23 into the long hole 26b. The minor axis dimension of the long hole 26b is aligned with the diameter of the engagement protrusion 23a, and the first blade body 26 is held between the support part 22 and the cover part 23 without play.

[0041] Although not shown, on one surface of the cover part 23 on the support part 22 side, there is a recess formed in the shape of the first blade body 26, and the first blade body 26 is accommodated in the recess. For this reason, outside the recess, the cover part 23 and the support part 22 are in contact without a gap, and the outer wall surfaces of the cover part 23 and the support part 22 form a seamless and smooth curved surface that is continuous without a joint. Also, by protruding one of the four corners of the first blade body 26 on the side opposite to the first blade tip 26a, the front and back of the first blade body 26 can be easily discriminated.

[0042] As shown in FIGS. 3 and 4, the support portion 22 and the cover portion 23 are structured to protrude toward the first cutting direction D1 side, and the tip of the support portion 22 protrudes slightly more than the tip of the cover portion 23. And the boundary surface between the support portion 22 and the cover portion 23 is slightly inclined with respect to the YZ plane having the central axis L as the normal direction. For this reason, the first blade body 26 fixed between the support portion 22 and the cover portion 23 is also inclined such that the first blade tip 26a located on the first cutting direction D1 side faces slightly downward.

[0043] A plurality of groove portions 24 are formed on the front wall surface of the support portion 22 and the cover portion 23 facing the first cutting direction D1, that is, the wall surface appearing in FIG. 1. And a plurality of first comb teeth 25 are constituted by the protrusion portions formed between the respective groove portions 24. The plurality of groove portions 24 and the plurality of first comb teeth 25 are formed so as to extend in the direction of the central axis L when the hair cutter 1 is viewed from the front as shown in FIG. 1.

[0044] The plurality of groove portions 24 are arranged at equal intervals along the Y-axis direction. Each groove portion 24 has the same width, and the arrangement interval is also an equal pitch. Also, each of the first comb teeth 25 formed on the support portion 22 and the cover portion 23 is configured at equal intervals and equal pitch. In the first blade portion 20, the distance from the first blade tip 26a to the tip of the first comb tooth 25 is shortened so that a short haircut can be performed. For this reason, the interval between the comb teeth of the first comb teeth 25 is narrowed to prevent skin cuts. And as shown in FIG. 1, the respective groove portions 24 formed in the support portion 22 and the cover portion 23 are formed at the same position in the Y-axis direction and are connected in the X-axis direction to form the same line. Similarly, each of the first comb teeth 25 formed in the support portion 22 and the cover portion 23 is formed at the same position in the Y-axis direction and is connected in the X-axis direction to form the same line.

[0045] Also, as shown in FIG. 5, a first structural portion 25a, which is a portion of the first comb tooth 25 on the cover portion 23 side, and a second structural portion 25b, which is a portion on the support portion 22 side, protrude toward the first cutting direction D1 side. The second structural portion 25b protrudes more than the first cutting edge 26a in the first cutting direction D1. The first structural portion 25a is configured such that the protruding amount is aligned with that of the first cutting edge 26a or protrudes more than the first cutting edge 26a in the first cutting direction D1. For this reason, the first cutting edge 26a is located inside the tip of the first comb tooth 25, and the first blade body 26 is surrounded by the first comb tooth 25.

[0046] Here, if the shortest distance from the tip of the first comb tooth 25 to the first cutting edge 26a is defined as a first distance, the hair length when cutting hair by the first blade portion 20 is determined based on this first distance. Specifically, as shown in FIG. 10, when cutting hair with the first blade portion 20, the hair 101 is cut such that the first comb tooth 25 touches the user's skin 100. At this time, the shortest distance from the skin 100 to the first cutting edge 26a becomes the hair cutting length. For this reason, the tip of the first comb tooth 25 that determines the hair cutting length is the location where the distance to the first cutting edge 26a is the shortest among the portions of the first comb tooth 25 that are in contact with the skin 100 when the first comb tooth 25 touches the user's skin 100. When the first comb tooth 25 is divided into the first structural portion 25a and the second structural portion 25b as in this embodiment, a gap is formed therebetween. In this case, regarding the gap, a virtual line connecting the tip of the first structural portion 25a and the tip of the second structural portion 25b, that is, the line indicating the skin 100 in FIG. 10 may be defined as the tip of the first comb tooth 25. The first distance can be arbitrarily set, but it is preferably 0.5 to 6 mm, and more preferably 1 to 4 mm.

[0047] Furthermore, each groove portion 24 is formed of a round groove with a rounded bottom, and the first comb teeth 25 are also formed as protrusions with a round cross-section whose tips are rounded. For this reason, including the portions of the first comb teeth 25 that protrude toward the first cutting direction D1 side among the first structural portion 25a and the second structural portion 25b, the tips of the first comb teeth 25 are rounded, and the feeling when the first comb teeth 25 contact the user's skin 100 during the use of the hair cutter 1 can be softened. Also, since the bottoms of the groove portions 24 are rounded, the adhesion of dirt into the groove portions 24 can be suppressed, and even if the cut hair 101 adheres, it can be easily removed.

[0048] In this way, the first blade portion 20 has a structure in which the first comb structure 27 is bridged between a pair of leg portions 21 erected at the tip portion 11. And a window portion 28 penetrating from the front side to the back side of the hair cutter 1 is formed between the tip portion 11, the pair of leg portions 21, and the first comb structure 27, so that the state of hair cutting can be confirmed through the window portion 28 during the use of the first blade portion 20.

[0049] With such a structure, the first blade portion 20 that cuts the hair 101 passing through the first comb teeth 25 with the first blade body 26 is configured.

[0050] 〔Configuration of the second blade portion 30〕 The second blade portion 30 is built in between the tip portion 11 and the gripping portion 13 of the body portion 10 and constitutes an L-shaped razor. And the second blade portion 30 performs hair cutting in a direction intersecting the central axis L and different from the first cutting direction D1, specifically, the direction toward the left side of the paper surface of FIG. 1 is defined as the second cutting direction D2.

[0051] The second blade portion 30 is composed of second comb teeth 31 formed of a part of the body portion 10, a holder 32 assembled to the opening portion 18 of the body portion 10, and a second blade body 33 provided in the holder 32.

[0052] As described above, the second comb teeth 31 are constituted by a plurality of protrusions 17 between a plurality of slits 16 formed in the body portion 10. The slits 16 are shaped to be recessed in a direction opposite to the second cutting direction D2, that is, from the left side to the right side of the paper surface of FIG. 1, of the body portion 10, and the second comb teeth 31 are shaped to protrude along the second cutting direction D2 from a base portion 15 that is the root portion. When the hair cutter 1 is viewed from the left side as shown in FIG. 4, the slits 16 and the second comb teeth 31 are formed along the Z-axis direction.

[0053] The plurality of slits 16 are arranged side by side at equal intervals along the X-axis direction. Each slit 16 has the same width, and the arrangement intervals are also at an equal pitch. Also, the second comb teeth 31 are also configured at equal intervals and equal pitch. However, in the second blade portion 30, the distance from the second blade tip 33a of the second blade body 33 to the tooth tip of the second comb teeth 31 is made longer so that a longer haircut than the first blade portion 20 is performed, and the interval between the comb teeth of the second comb teeth 31 is also made wider than the interval between the comb teeth of the first comb teeth 25. Also, when performing a haircut, it is done while holding the gripping portion 13, but even if the second blade portion 30 is held, the interval of the slits 16 is set so that the flesh of the hand does not touch the second blade body 33.

[0054] Also, as shown in FIG. 1, the second comb teeth 31 protrude more in the second cutting direction D2 than the second blade tip 33a. For this reason, the second blade tip 33a is located inside the tip of the second comb teeth 31, and the second blade body 33 is surrounded by the second comb teeth 31.

[0055] As shown in FIG. 8, the holder 32 is a component in which the second blade body 33 is housed and integrated inside. The holder 32 has a bottom portion 32a corresponding to the shape of the opening 18 formed in the body portion 10, and when it is fitted into the opening 18 together with the second blade body 33, it is integrated with the body portion 10 so as to lid-close the opening 18 by the bottom portion 32a. As described above, the bottom portion 32a is shaped to be recessed in an arc shape, and the portion recessed in the arc shape constitutes the finger attachment portion 19.

[0056] As shown in FIG. 11, the holder 32 accommodates the second blade body 33 so as to sandwich it. As shown in FIG. 8, the holder 32 has a protrusion 32b at a position corresponding to the second comb tooth 31 protruding in the second cutting direction D2 from the second blade tip 33a, and a recess 32c at a position corresponding to the slit 16 being recessed from the second blade tip 33a. When the holder 32 is fitted into the opening 18, the protrusion 32b fits into the second comb tooth 31, and as shown in FIG. 1, the recess 32c is disposed at the tip of the slit 16, and the second blade tip 33a is exposed at the tip of the slit 16.

[0057] As shown in FIG. 11, the holder 32 is composed of two parts, a first part 32d that is brought into contact with one surface side of the second blade body 33 and a second part 32e that is brought into contact with the other surface side of the second blade body 33. The first part 32d is integrally formed with a wall surface 32f that contacts one surface of the second blade body 33 in addition to the bottom 32a. The second part 32e has a shape corresponding to the wall surface 32f of the first part 32d. The second part 32e is provided with cylindrical engagement protrusions 32g at two positions arranged in the X-axis direction, and the second part 32e is assembled to the first part 32d by fitting the engagement protrusions 32g into through holes 32h formed in the wall surface 32f. Further, a cylindrical protrusion 32i for positioning the second blade body 33 is formed on the second part 32e separately from the engagement protrusion 32g.

[0058] As shown in FIG. 7, the second blade body 33 is in the shape of a substantially rectangular plate, and a haircut is performed with one side of the long side facing the second cutting direction D2 as the second blade tip 33a. An oval-shaped long hole 33b corresponding to the protrusion 32i is formed inside the second blade body 33, and the first part 32d and the second part 32e are assembled such that the protrusion 32i is inserted into the long hole 33b. The minor axis of the long hole 33b is aligned with the diameter of the protrusion 32i, and the diameter of the engagement protrusion 32g is aligned with the diameter of the through hole 32h, so that the second blade body 33 is held between the first part 32d and the second part 32e without play.

[0059] Although not shown in the drawings, on one surface of the first component 32d on the side of the second component 32e, there is a recess formed in the shape of the second blade body 33, and the second blade body 33 is accommodated in the recess. Therefore, outside the recess, the first component 32d and the second component 32e are in contact with each other without a gap.

[0060] Regarding the protrusions 32b provided on each of the first component 32d and the second component 32e, they may have a symmetrical shape centered on the second blade body 33, but here they have different shapes. Specifically, as shown in FIG. 11, regarding the protrusion 32b on the second component 32e side, it slightly protrudes from the second blade tip 33a or has the same protruding amount as the second blade tip 33a. And regarding the protrusion 32b on the first component 32d side, it is made into a claw shape that protrudes more than the second blade tip 33a and wraps around to reach the tip of the protrusion 32b on the second component 32e side while covering the second blade tip 33a. Thus, when assembling the second component 32e after attaching the second blade body 33 to the first component 32d, by placing the second blade tip 33a against the claw-shaped portion of the protrusion 32b of the first component 32d, the positioning of the second blade body 33 can be achieved.

[0061] Together with the holder 32 configured as described above, the second blade body 33 is fitted into the opening 18 of the body portion 10 and integrated with the body portion 10 such that the second blade tip 33a of the second blade body 33 is directed in the second cutting direction D2. And the second blade body 33 is surrounded by the second comb teeth 31, and a second comb structure 34 is formed by the second comb teeth 31, the holder 32, and the second blade body 33. With such a structure, a second blade portion 30 for cutting the hair 101 passing through the second comb teeth 31 with the second blade body 33 is formed.

[0062] Note that also in the second blade portion 30, the bottom 35 of the slit 16 and the tips of the second comb teeth 31 are also rounded in cross section. For this reason, when the second comb teeth 31 hit the user's skin 100 during the use of the hair cutter 1, the feeling can be softened. Also, since the bottom 35 of the slit 16 is rounded, the adhesion of dirt to the bottom 35 can be suppressed, and even if the cut hair 101 adheres, it can be easily removed.

[0063] Here, if the shortest distance from the tooth tip of the second comb tooth 31 to the second cutting edge 33a is defined as the second distance, the length of the hair 101 when cutting the hair with the second blade portion 30 is determined based on this second distance. That is, when cutting the hair with the second blade portion 30, similar to the first blade portion 20, the second comb tooth 31 touches the user's skin 100 to cut the hair 101, and the shortest distance from the skin 100 to the second cutting edge 33a at that time becomes the length of the hair cut. Therefore, the tooth tip of the second comb tooth 31 that determines the length of the hair cut is the location where the distance to the second cutting edge 33a is the shortest among the portions of the second comb tooth 31 that are in contact with the skin 100 when the second comb tooth 31 touches the user's skin 100. When the second comb tooth 31 is formed in an oval cross-section according to the overall shape of the body portion 10 as in the present embodiment, the distance from the second cutting edge 33a is substantially equal throughout the entire area of the second comb tooth 31. Therefore, the distance between the tooth tip of the second comb tooth 31 and the second cutting edge 33a in the Z-axis direction may be defined as the second distance. The second distance can also be arbitrarily set, but it is preferably 6 to 20 mm, and more preferably 8 to 12 mm.

[0064] 〔Usage method of the hair cutter 1〕 As described above, the hair cutter 1 is provided with two types of razors, namely, the first blade portion 20 composed of a T-shaped razor and the second blade portion 30 composed of an L-shaped razor. Therefore, the user can perform hair cutting using the type of razor suitable for the part where the hair cutting is to be done.

[0065] For example, for the I-zone and the O-zone, there is a desire to perform a hair cut that can cut the hair 101 more finely and shorter. When performing a hair cut in these zones, the first blade portion 20 is used. For example, as shown in FIG. 12, hold the hair cutter 1 so that the back side is positioned between the thumb and the index finger when the palm is facing up, and hold the grip portion 13 with all fingers. In this state, direct the first cutting edge 26a side of the first blade portion 20 toward the hair 101 to be cut, and move the first blade portion 20 in the first cutting direction D1.

[0066] As a result, the hair 101 passing through the first comb teeth 25 can be cut by the first blade body 26. At this time, since the first distance from the tip of the first comb teeth 25 to the first blade tip 26a is shortened, the hair 101 in the I zone and the O zone can be cut short. In particular, since the first blade part 20 is configured as a T-shaped razor, it is suitable for shaving the hair 101 shorter, and it can be shaved short to a length where almost no hair 101 remains. As a result, it becomes possible to keep the I zone and the O zone clean.

[0067] Also, when cutting hair using the first blade part 20, it is difficult to cut hair while looking at the first blade body 26 depending on the location where the hair is cut. However, in the case of the hair cutter 1 of the present embodiment, it is possible to cut hair while checking the first blade part 20 through the window part 28, enabling a more comfortable and accurate hair cut.

[0068] On the other hand, for the V zone, there is a desire to cut the hair relatively long and evenly. For hair cutting in such a case, the second blade part 30 is used. For example, as shown in FIG. 13, in the case of a right-handed user, press the finger rest part 19 of the hair cutter 1 with the index finger, and grasp the grip part 13 so that the thumb side is on the front side of the hair cutter 1 and the middle finger, ring finger, and little finger are on the back side of the hair cutter 1. In this state, direct the second blade tip 33a side of the second blade part 30 toward the hair 101 side to be cut, and move the second blade part 30 in the second cutting direction D2. At this time, if the hair 101 to be cut is slightly pulled with the left hand while cutting the hair with the second blade part 30, it becomes easier to cut the hair 101 to the desired length. As a result, the hair 101 passing through the second comb teeth 31 can be cut by the second blade body 33. At this time, since the second distance from the tip of the second comb teeth 31 to the second blade tip 33a is longer than the first distance, the hair 101 in the V zone can be cut so as to be relatively long and even. As a result, the hair 101 in the V zone can be neatly aligned while leaving it at a certain length, and the V zone can be kept clean. Here, the case of a right-handed user is taken as an example, but even in the case of a left-handed user, the hair can be cut in the same way by simply turning the hair cutter 1 inside out compared to the right-handed case.

[0069] [Effect of the hair cutter 1] (1) The hair cutter 1 of the present embodiment has a structure in which the first blade portion 20 and the second blade portion 30 are arranged on the same side with respect to the grip portion 13. Therefore, when using the first blade portion 20 and the second blade portion 30, hair cutting can be performed using the first blade portion 20 and the second blade portion 30 without changing the way of holding the grip portion 13 in the vertically inverted direction.

[0070] Further, since the first blade portion 20 and the second blade portion 30 are arranged close to one side with respect to the grip portion 13, the grip portion 13 can be held when performing hair cutting using any of the blade portions.

[0071] Usually, when designing a hair cutter in which two blade portions are integrated, as shown in Patent Document 1, a structure is adopted in which one blade portion is provided on each side of the grip portion. In such a structure, when trying to perform hair cutting using one blade portion, it becomes a form of holding the other blade portion, and there is resistance from the user's psychology. To make a structure in which it is not necessary to hold the other blade portion, it is necessary to lengthen the grip portion. On the other hand, the hair cutter 1 of the present embodiment is based on an idea different from the conventional one in which the second blade portion 30 is built in the body portion 10, and realizes a structure in which the first blade portion 20 and the second blade portion 30 are arranged close to one side with respect to the grip portion 13. Because of such a structure, it does not become a form of holding the other blade portion when using one blade portion. Thereby, when using the hair cutter 1, it becomes possible to give a sense of security to the user.

[0072] However, when using the first blade portion 20, it may be possible to hold near the second blade portion 30. However, the second blade portion 30 is for aligning the hair 101 long, and in addition to the second distance from the second blade tip 33a to the tooth tip of the second comb tooth 31 being lengthened, the interval of the slit 16 is set so that the flesh of the hand does not touch the second blade body 33. For this reason, even if the hand touches the second blade portion 30, it can be guarded by the second comb tooth 31 and the hand will not be cut, so that the user can be given a further sense of security.

[0073] (2) Since the first cutting direction D1 for hair cutting by the first blade portion 20 and the second cutting direction D2 for hair cutting by the second blade portion 30 are different directions, the hair cutter 1 will be moved in different directions for each part where hair cutting is performed. Therefore, shaving mistakes can be prevented.

[0074] (3) A window portion 28 surrounded by a pair of leg portions 21, the first comb structure 27, and the tip portion 11 of the body portion 10 is formed between the first comb structure 27 and the body portion 10. Therefore, when performing hair cutting by the first blade portion 20, it is possible to easily confirm the place where hair cutting is to be done.

[0075] (4) Recesses 21a are provided in the pair of leg portions 21. Therefore, only the first comb structure 27 touches the skin during hair cutting, and it is possible to make the leg portions 21 less likely to touch, making it easier to perform hair cutting.

[0076] (5) Since two types of razors, the first blade portion 20 and the second blade portion 30, are provided, the hair 101 can be cut short by the first blade portion 20 and the hair 101 can be cut to be aligned longer than the first blade portion 20 by the second blade portion 30. In this way, since it is possible to perform hair cutting of different lengths with the first blade portion 20 and the second blade portion 30, it is possible to adjust the hair 101 to different lengths according to one's preference by using the appropriate one of the first blade portion 20 and the second blade portion 30 according to the part where hair cutting is performed.

[0077] For example, by making the second distance from the second blade tip 33a to the tooth tip of the second comb teeth 31 in the second blade portion 30 longer than the first distance from the first blade tip 26a to the tooth tip of the first comb teeth 25 in the first blade portion 20, hair cutting of different lengths becomes possible.

[0078] (6) When viewed from the direction along the central axis L, all of the first blade portion 20 is within the dimensions of the gripping portion 13 in the radial direction centered on the central axis L. For this reason, the size of the first blade portion 20 can be suppressed, and the first blade portion 20 can be prevented from getting in the way when performing a haircut in the delicate zone. Further, when the hair cutter 1 is placed on a floor surface such as a table, it is possible to suppress the first blade portion 20 from locally hitting the floor surface, and it is possible to suppress damage to the first blade portion 20.

[0079] (7) In the portion of the body portion 10 where the second blade portion 30 is disposed, a finger rest portion 19 in which the body portion 10 is partially recessed is provided on the side opposite to the side toward which the second blade tip 33a is directed. Thereby, the ease of gripping of the gripping portion 13 when using the second blade portion 30 can be improved, and a stable haircut can be achieved when using the second blade portion 30.

[0080] (8) The interval between the teeth in the second comb teeth 31 is wider than the interval between the teeth in the first comb teeth 25. In this way, for the first blade portion 20 that constitutes the T-shaped razor, the hair 101 can be made to enter and cut in a direction close to perpendicular to the first blade tip 26a by narrowing the interval between the first comb teeth 25. Further, for the second blade portion 30 that constitutes the L-shaped razor, by widening the interval between the second comb teeth 31, the hair 101 can be cut so that it can move not only in a component perpendicular to the second blade tip 33a but also in a component along the direction of the second blade tip 33a.

[0081] And by providing the two functions of the T-shaped razor and the L-shaped razor, there is no need to prepare the T-shaped razor and the L-shaped razor separately. Therefore, this also leads to a reduction in waste, which corresponds to "SDGs Goal 12. Responsibility to produce, responsibility to use, Target 12.5 By 2030, significantly reduce waste generation through prevention, reduction, recycling and reuse of waste".

[0082] (9) The gripping portion 13 of the body portion 10 is formed in a cylindrical shape with the rear end portion 12 side being open. As a result, the body portion 10 can be configured with a simple structure of a cylindrical shape with the rear end portion 12 side being open. Also, with such a simple structure, meat theft can be configured, so when the body portion 10 is configured by resin molding or the like, deformation of the body portion 10 due to heat shrinkage or the like can be suppressed, and the body portion 10 can be formed into a stable shape.

[0083] (10) Since the first blade portion 20 and the second blade portion 30 are arranged close to one side of the body portion 10, the other side can be configured only by the gripping portion 13, and the rear end portion 12 can be made flat. For this reason, when not in use, it is also possible to store the hair cutter 1 vertically with the rear end portion 12 as the bottom surface. Therefore, it is not necessary to prepare a large space as the storage space for the hair cutter 1.

[0084] (Other embodiments) The present disclosure is not limited to the above-described embodiments, and can be appropriately modified within the scope described in the claims. In the above embodiments, it goes without saying that the elements constituting the embodiments are not necessarily essential, except in cases where it is explicitly stated that they are essential or when they are considered to be clearly essential in principle. Also, in the above embodiments, when numerical values such as the number, numerical value, amount, range, etc. of the components are mentioned, they are not limited to that specific number, except in cases where it is explicitly stated that they are essential or when they are clearly limited to a specific number in principle. Further, in the above embodiments, when referring to the shape, positional relationship, etc. of the components, etc., they are not limited to that shape, positional relationship, etc., except in cases where it is explicitly stated or when they are clearly limited to a specific shape, positional relationship, etc. in principle.

[0085] For example, in the above-described embodiment, the cover portion 23 of the first blade portion 20 is configured as a separate component from the body portion 10. However, by integrally molding the first blade body 26 when forming the body portion 10, the first blade portion 20 can also have an integral structure with the body portion 10. Conversely, although the pair of leg portions 21 and the support portion 22 are configured as a single component with the body portion 10, they may be configured as separate components and assembled to the tip of the body portion 10.

[0086] Also, in the above-described embodiment, the holder 32 of the second blade portion 30 is configured as a separate component from the body portion 10. However, by integrally molding the second blade body 33 when forming the body portion 10, the second blade portion 30 can also have an integral structure with the body portion 10.

[0087] Further, in the above-described embodiment, the meat theft is formed by opening the grip portion 13 from the rear end portion 12 side to form the hollow portion 14. However, instead of from the rear end portion 12 side, a plurality of recesses for forming the meat theft may be provided on the side surface of the grip portion 13, such as the recess 13a.
