[0011] Hereinafter, embodiments will be described in detail with reference to the drawings. However, unnecessary detailed description may be omitted. For example, detailed description of already well-known matters or redundant description of substantially the same configuration may be omitted.

[0012] The accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0013] In the following embodiments, a hair clipper for cutting human hair, animal hair, and the like will be exemplified as the cutting device.

[0014] In the following embodiments, the direction in which the attachment is attached to and detached from the cutting device is referred to as the Z direction (vertical direction: first direction), the direction in which the comb portion protrudes is referred to as the X direction (front-to-back direction: second direction), and the direction intersecting (orthogonal to) the X and Z directions is referred to as the Y direction (width direction: third direction).

[0015] The description will be given with the attachment positioned on the lower side and the cutting device positioned on the upper side, defining the up-down direction of the attachment.

[0016] In the following embodiments, the side from which the first comb portions protrude will be defined as the front side of the attachment (forward in the X direction) for the sake of convenience.

[0017] In the following description of the cutting device, the longitudinal direction of the body is defined as the up-down direction, the side of the body where the power switch is located is defined as the front side, the direction perpendicular to the up-down direction and the front-to-back direction is defined as the width direction, and the side of the body where the head is located is defined as the upper side.

[0018] (Embodiment) 1 to 6, hair clippers (an example of a cutting device) 1 according to this embodiment includes a body 10 having a drive shaft 16 driven by a rotary motor 15, and a head 20 provided with a blade unit 23 and removably attached to the body 10. The hair clippers 1 are a device that can be used, for example, to cut the hair H of a user or the like to a desired length.

[0019] [Example of body configuration] Here, an example of the configuration of the body 10 will be described.

[0020] The body 10 is cylindrical and elongated in the vertical direction, and is sized so that the user can hold it in one hand. That is, when using the hair clippers 1, the user can hold the body 10.

[0021] In this embodiment, the body 10 includes a housing 11 that forms an outer shell, as shown in Figures 2 to 5. The housing 11 can be made of, for example, an insulating synthetic resin material.

[0022] In this embodiment, the housing 11 is formed by joining a plurality of divided bodies, and a cavity is formed inside the housing 11 formed by joining the divided bodies. Various electrical components are accommodated inside this cavity.

[0023] Specifically, as shown in Figure 2, the housing 11 includes a cylindrical wall portion 12 that is approximately cylindrical and penetrates in the vertical direction, an upper lid portion 13 that is arranged to cover the upper opening of the cylindrical wall portion 12, and a lower lid portion 14 that is arranged to cover the lower opening of the cylindrical wall portion 12.

[0024] In this embodiment, as shown in FIGS. 3 and 4, a surface having a curvature different from that of the other portions is formed at the rear portion of the cylindrical wall portion 12 in the front-rear direction so as to extend vertically in an elongated manner. That is, the cylindrical wall portion 12 has a first surface 121 curved in an arc shape and a second surface 122 connected to both ends of the first surface 121 and having a curvature different from that of the first surface 121. In this embodiment, the curvature of the second surface 122 is made smaller than that of the first surface 121. Specifically, the curvature of the second surface 122 is made to be approximately zero, and the second surface 122 is formed to be a substantially flat surface. In this case, the second surface 122 may be formed so that the curvature is the same at any position in the vertical direction (axial direction of the drive shaft 16). Alternatively, the second surface 122 may be formed so that the curvature at any position in the vertical direction (axial direction of the drive shaft 16) is different from that of the other portions. In this embodiment, as shown in Figures 3 and 4, the second surface 122 is formed so that it is a flat surface (with zero curvature) where the vertical wall portion 1322 is formed, and in other areas it is a concave surface that is curved slightly inward (towards the drive shaft 16).

[0025] Furthermore, in this embodiment, the outer peripheral surface of the cylindrical wall portion 12 is configured to define the contour shape D of the body 10 when viewed in the vertical direction (the axial direction of the drive shaft 16). Therefore, in this embodiment, the contour shape D of the body 10 when viewed in the vertical direction (the axial direction of the drive shaft 16) has a shape including a first line portion D1 that is an arc with a predetermined curvature and a second line portion D2 that has a curvature different from that of the first line portion D1, as shown in FIGS. 4 and 5 . Here, in this embodiment, the curvature of the second line portion D2 is configured to be smaller than that of the first line portion D1. Specifically, the curvature of the second line portion D2 is configured to be approximately zero, and the second line portion D2 is configured to be approximately linear. As described above, in this embodiment, the second surface 122 is configured to be flat where the vertical wall portion 1322 is formed and concave wherever else it is formed. Therefore, the second line portion D2 is straight in the area where the vertical wall portion 1322 is formed, and is an arcuate line that curves inward in other areas, thereby giving the body 10 a D-cut structure.

[0026] In this way, by giving the body 10 a D-cut shape, it becomes easier to grasp the front and rear directions of the body 10 when holding the body 10. Furthermore, by giving the body 10 a D-cut shape, it becomes possible to prevent the body 10 from rolling when placed on a washbasin or the like.

[0027] In addition, in this embodiment, as shown in FIG. 5, a cavity formed inside the housing 11 houses the rotary motor 15, a rechargeable battery 171 that supplies power to the rotary motor 15, a control board 172 that controls the on / off of the power supply (on / off of driving the rotary motor 15), and the like.

[0028] Specifically, the rotary motor 15 is built into the upper part of the housing 11, and the rechargeable battery 171 is built into the lower part of the housing 11, i.e., below the rotary motor 15, with its longitudinal direction roughly aligned with the up-down direction. By arranging the rotary motor 15 and the rechargeable battery 171 side by side in the up-down direction in this way, it is possible to make the body 10 more compact in the width direction. A control board 172 is built into the cavity of the housing 11 in front of the rechargeable battery 171.

[0029] The rotary motor 15 includes a rotary motor body 151 and a rotary motor shaft 152, and is housed in the cavity of the housing 11 with the rotary motor shaft 152 protruding upward from the rotary motor body 151. That is, the rotary motor 15 is housed in the cavity of the housing 11 with the direction of the rotation axis generally aligned with the up-down direction. The drive shaft 16 is attached to the rotary motor shaft 152 that protrudes upward.

[0030] The rechargeable battery 171 may be a lithium ion rechargeable battery, a nickel-metal hydride rechargeable battery, or the like.

[0031] Furthermore, a push-type power switch 123 for turning the power on and off (turning the drive of the rotary motor 15 on and off) is formed in approximately the center in the vertical direction at the front of the cylindrical wall portion 12 so as to face the control board 172. Note that although the push-type power switch 123 is exemplified as the power switch in this embodiment, any switch that can turn the power on and off may be used, such as a slide switch.

[0032] Furthermore, the top cover 13 is a wall portion arranged to cover the upper opening of the cylindrical wall portion 12, and includes a rotary motor holding wall 131 that holds the rotary motor 15. Furthermore, the top cover 13 includes a movable wall 132 that is arranged above the rotary motor holding wall 131 in a state in which it can slide in the front-to-rear direction, and a pressing wall 133 that suppresses relative movement of the movable wall 132 in the up-and-down direction. In this embodiment, the top cover 13 is formed by fixing the rotary motor holding wall 131 and the pressing wall 133 with screws 173, with the movable wall 132 sandwiched between them.

[0033] Then, by inserting the rotary motor holding wall 131 into the cylindrical wall portion 12 from the upper opening of the cylindrical wall portion 12 with the rotary motor holding wall 131 facing downward, the upper opening of the cylindrical wall portion 12 is covered with the upper cover portion 13. At this time, the rotary motor holding wall 131 is inserted into the cylindrical wall portion 12 with the gap between the outer peripheral surface of the rotary motor holding wall 131 and the inner peripheral surface of the cylindrical wall portion 12 sealed by the packing 174.

[0034] Furthermore, a through-hole 1311 is formed in the rotary motor holding wall 131 at a position corresponding to the drive shaft 16, and the rotary motor 15 is held by the rotary motor holding wall 131 with the drive shaft 16 attached to the rotary motor shaft 152 inserted into the through-hole 1311. At this time, the rotary motor 15 is held by the rotary motor holding wall 131 with the gap between the rotary motor shaft 152 and the through-hole 1311 sealed by a waterproof rubber 175. This prevents water from entering the cavity of the housing 11 when the body 10 is washed with water, for example.

[0035] Furthermore, in this embodiment, no plate material is present in the movable wall 132 or the retaining wall 133 at a position corresponding to the drive shaft 16, and the drive shaft 16 is exposed to the outside, at least in a plan view of the body 10 (when the body is viewed from above in the vertical direction). This makes it possible to attach a power transmission unit 241 (described later) provided on the head 20 to the drive shaft 16 when the head 20 is attached to the body 10.

[0036] As shown in FIG. 3, the drive shaft 16 has a regular hexagonal (polygonal) shape in a plan view of the body 10 (viewing the body from above in the vertical direction), allowing the power transmission unit 241 to be attached to the drive shaft 16 in a manner that suppresses freewheeling. The drive shaft 16 and power transmission unit 241 are not limited to a polygonal shape as long as they are attached in a manner that suppresses freewheeling. For example, a drive shaft with a D-cut structure like the body 10 described above, i.e., a drive shaft with a D-cut structure, may also be used. Freewheeling may also be suppressed by using a means for increasing the frictional force between the drive shaft 16 and the power transmission unit 241.

[0037] In addition, in this embodiment, the movable wall 132 is provided with a hook (fitting portion) 1321 that protrudes upward and engages with a hook (fitting portion) 2222 provided on the head 20 when the head 20 is attached to the body 10.

[0038] 3 and 5, in this embodiment, three (plural) hooks 1321 are provided spaced apart from one another on the movable wall 132. All three hooks 1321 are provided such that the portions for hooking the hooks 2222 protrude rearward in the front-rear direction.

[0039] Furthermore, a vertical wall portion 1322 is provided at the rear end of the movable wall 132 so as to extend upward. By pushing this vertical wall portion 1322 forward in the front-to-rear direction, the hook 1321 (movable wall 132) moves forward relative to the rotation motor holding wall 131 and the pressing wall 133.

[0040] By providing such hook 1321 and vertical wall portion 1322 on the movable wall 132, the vertical wall portion 1322 functions as a release button that releases the engagement between the hook 1321 and the hook 2222.

[0041] In this embodiment, the retaining wall 133 includes a top wall 1331 that covers the movable wall 132 from above and a peripheral wall 1332 that extends downward from the outer periphery of the top wall 1331. The top wall 1331 has a through-hole 1331a through which at least a portion of the hook 1321 is exposed in a plan view of the body 10 and into which the hook 2222 on the head 20 is inserted when the head 20 is attached to the body 10. The top wall 1331 also has a cylindrical rib 1331b that protrudes upward and surrounds the entire periphery of the drive shaft 16. The cylindrical rib 1331b functions to guide the connection between the drive shaft 16 and the power transmission unit 241 when the head 20 is attached to the body 10. The top wall 1331 also has a restricting wall 1331c that restricts the vertical wall portion 1322 from moving too far forward.

[0042] The peripheral wall 1332 is a portion that is inserted into the peripheral wall (upper wall 221) of the head 20 when the head 20 is attached to the body 10.

[0043] In this embodiment, the body 10 and head 20 are provided with vibration receiving sections that can receive vibrations in three or more intersecting directions on a plane perpendicular to the drive shaft 16. This makes it possible to dampen vibrations regardless of which of various heads that vibrate in different directions is attached to the body 10.

[0044] In this embodiment, three hooks (fitting portions) 1321, 2222 provided on the body 10 and the head 20, respectively, are designed to also function as vibration receiving portions.

[0045] It should be noted that the body 10 and the head 20 may be provided with hooks (fitting portions) 1321 and 2222 at four or more locations.

[0046] Furthermore, it is preferable that the three or more hooks (fitting portions) 1321, 2222 are provided so as to be positioned on the same imaginary circumference centered on the drive shaft 16. In this case, it is more preferable that they are provided at equal intervals on the same imaginary circumference centered on the drive shaft 16.

[0047] If a fitting portion is provided so as to surround the entire circumference of the drive shaft 16, one fitting portion can receive vibrations in various directions. Also, if two semicircular fitting portions are provided so as to surround the drive shaft 16, vibrations in various directions can also be received.

[0048] Furthermore, it is also possible to provide a vibration receiving portion that can receive vibrations in three or more directions that intersect with each other on a plane perpendicular to the drive shaft 16, separate from the fitting portion.

[0049] 5, lower lid portion 14 is a wall portion arranged to cover the lower opening of cylindrical wall portion 12, and includes an outer wall 141 having a generally spherical truncated shape whose diameter decreases downward, and an inner wall 142 arranged inside outer wall 141. In this embodiment, lower lid portion 14 is formed by fixing outer wall 141 and inner wall 142 with screws 173.

[0050] Then, by inserting the upper part of inner wall 142 into cylindrical wall portion 12 from the lower opening of cylindrical wall portion 12, the lower opening of cylindrical wall portion 12 is covered with lower cover portion 14. At this time, the upper part of inner wall 142 is inserted into cylindrical wall portion 12 with packing 174 sealing the gap between the outer peripheral surface of the upper part of inner wall 142 and the inner peripheral surface of cylindrical wall portion 12.

[0051] A connector 14a is formed on the underside of the lower cover 14, into which a charging cable or the like (not shown) can be inserted. That is, by inserting a charging cable or the like into the connector 14a, the rechargeable battery 171 can be charged. Note that the method of charging the rechargeable battery 171 is not limited to inserting a charging cable or the like into the connector 14a, and other methods, such as a charging method using contactless power supply or a charging method using long-distance power transmission using a power transmission system, can also be used.

[0052] [Example of head configuration] Next, an example of the configuration of the head 20 will be described.

[0053] In this embodiment, the head 20 includes a head main body 21 that is detachably attached to the body 10 , and a blade unit 23 that is detachably attached to the head main body 21 .

[0054] The head body 21 includes a head housing 22 that forms the outer shell of the head body 21. The head housing 22 can be made of, for example, an insulating synthetic resin material.

[0055] The head housing 22 is formed by joining together a number of divided bodies, and a cavity is formed inside the head housing 22 formed by joining together the divided bodies. As shown in Figure 6, a conversion mechanism 244, which will be described later, is housed in this cavity.

[0056] The head housing 22 includes an upper wall 221 that opens downward, and a lower lid portion 222 that is disposed so as to cover the lower opening of the upper wall 221. In this embodiment, the upper wall 221 and the lower lid portion 222 are integrally formed.

[0057] A notch 2221 is formed in the lower rear end of the lower cover 222 to prevent the lower cover 222 from interfering with the restricting wall 1331c and vertical wall 1322 of the body 10 when the head 20 is attached to the body 10. The restricting wall 1331c, the vertical wall 1322, and the notch 2221 also determine the attachment direction of the head 20 when the head 20 is attached to the body 10.

[0058] The lower cover 222 is a wall disposed to cover the lower opening of the upper wall 221, and three hooks (fitting portions) 2222 are provided to protrude downward on the lower cover 222. The three hooks 2222 are provided at positions corresponding to the three hooks 1321 of the body 10, and each of the hooks is provided so that the portion for hooking the hook 1321 protrudes forward in the front-to-rear direction.

[0059] The lower cover 222 holds a power transmission unit 241 of the power transmission mechanism 24 so as to be surrounded by the three hooks 2222. Inside this power transmission unit 241, a regular hexagonal (polygonal) space is formed so as to open downward when viewed from the back side of the head 20 (when viewing the head 20 from below in the up-down direction). This regular hexagonal (polygonal) space is formed to have approximately the same size as the outer diameter of the drive shaft 16, and when the head 20 is attached to the body 10, the drive shaft 16 is inserted into this regular hexagonal (polygonal) space.

[0060] The head 20 has the power transmission mechanism 24 that has the above-mentioned power transmission unit 241 and is capable of transmitting the power (rotation) of the rotary motor 15.

[0061] The power transmission mechanism 24 includes an operating shaft 242 that is attached to and operates on the above-described power transmission unit 241. The operating shaft 242 is inserted and fixed in an insertion hole 2411 formed in the upper part of the power transmission unit 241, and rotates together with the power transmission unit 241 that rotates by the power (rotation) of the rotary motor 15 transmitted from the drive shaft 16.

[0062] The power transmission mechanism 24 is held by the upper wall 221 in a state in which the upper end of the operating shaft 242 is disposed within the cavity in which the conversion mechanism 244 is housed.

[0063] The power transmission mechanism 24 is also provided with a conversion mechanism 244 attached to the operating shaft 242, which converts rotational motion into reciprocating linear motion in the width direction, and this conversion mechanism 244 is connected to a holding plate (acting portion) 235, which will be described later. In other words, the conversion mechanism 244 is interposed between the operating shaft 242 and the holding plate (acting portion) 235. In this way, the power of the rotary motor 15 causes the holding plate (acting portion) 235 to perform reciprocating linear motion in the width direction.

[0064] The conversion mechanism 244 includes a base 2441 attached to the upper end of the operating shaft 242. The base 2441 is attached to the operating shaft 242 so as to rotate together with the operating shaft 242.

[0065] The conversion mechanism 244 also includes an eccentric shaft 2442 attached to the base 2441 in an eccentric state relative to the operating shaft 242, and a link 2443 attached to the eccentric shaft 2442 and connected to the connection portion 2351 of the holding plate (acting portion) 235.

[0066] In this way, the rotational movement of the rotary motor 15 is converted into a reciprocating movement in the width direction of the holding plate (action portion) 235 .

[0067] The head body 21 having such a configuration has a blade unit 23 detachably attached thereto.

[0068] The blade unit 23 is provided with a blade portion 231 and has the function of cutting hair. In the head 20 according to this embodiment, the width of the blade portion 231 is greater than the diameter of the body 10.

[0069] The blade portion 231 includes a fixed blade 2321 and a movable blade 2331 that slides back and forth relative to the fixed blade 2321. The movable blade 2331 is configured to move back and forth relative to the fixed blade 2321 in the width direction.

[0070] Specifically, the blade unit 23 includes a fixed plate 232 on which a plurality of fixed blades 2321 are formed, and a movable plate 233 on which a plurality of movable blades 2331 are formed. The blade unit 23 also includes a frame 234 that supports the fixed plate 232, and a holding plate 235 that supports the movable plate 233. The blade unit 23 also includes a spring 2341 that is attached to the frame 234 and presses the movable plate 233 against the fixed plate 232, thereby bringing the fixed blade 2321 and the movable blade 2331 into contact with each other.

[0071] The fixed plate 232 and the movable plate 233 are disposed so as to face each other in the front-rear direction. The frame 234 supports the fixed plate 232 from the rear side (the side opposite to the side on which the movable plate 233 is disposed relative to the fixed plate 232). This prevents the fixed plate 232 from shifting out of position. The holding plate 235 supports the movable plate 233 from the front side (the side opposite to the side on which the fixed plate 232 is disposed relative to the movable plate 233). This prevents the movable plate 233 from shifting out of position.

[0072] As the spring 2341 that brings the fixed blade 2321 and the movable blade 2331 into contact with each other, for example, a torsion spring can be used, and this torsion spring (spring 2341) is attached to the frame 234.

[0073] Furthermore, a connection part 2351 is provided on the holding plate 235, and with the blade unit 23 attached to the head main body 21, this connection part 2351 is connected to a link 2443 of the conversion mechanism 244. In this way, when the rotary motor 15 is driven, only the force in the width direction of the blade unit 23 is transmitted from the link 2443 to the connection part 2351, and the movable plate 233 moves back and forth in the width direction of the blade unit 23 via the holding plate 235. The movable blade 2331 then slides back and forth relative to the fixed blade 2321, and the hair H is pinched and cut between the movable blade 2331 and the fixed blade 2321.

[0074] In this embodiment, an attachment 3 that adjusts the length (length after cutting) of the cut hair (hair) H can be detachably attached to the head 20. When such an attachment 3 is attached to the head 20, the blade part 231, which is a functional part of the head 20, is protected by the attachment 3.

[0075] [Example of attachment configuration] Next, an example of the configuration of the attachment 3 will be described.

[0076] As shown in Figures 7 to 14, the attachment 3 in this embodiment comprises a substrate (base) 30 in the shape of a substantially rectangular plate extending in a substantially horizontal direction, a comb portion 40 provided on the substrate (base) 30 and protruding in the X direction (front-to-back direction: second direction), and a clamping wall 70 provided on the substrate (base) 30 and capable of clamping the hair clippers 1 from both sides in the Y direction (width direction: third direction).

[0077] The comb section 40 has the function of guiding the hair H to the blade section 231 while styling it, and as shown in Figure 8, has multiple combs 45 arranged side by side and spaced apart in the Y direction (width direction: third direction).

[0078] In this embodiment, each comb 45 is generally plate-shaped and is connected to the substrate (base) 30 with the plate thickness direction generally aligned with the Y direction (width direction: third direction) and protruding in the X direction (front-rear direction: second direction) as shown in Figures 9 to 11.

[0079] By doing so, when cutting hair H using the comb portion 40, the hair H can be introduced into the space formed between adjacent combs 45, and the introduced hair H is guided to the blade portion 231 while being shaped. Then, the guided hair H is cut by the blade portion 231.

[0080] 12, the comb portion 40 has an opposing surface 41 located on the upper side (one side) in the Z direction (vertical direction: first direction) and capable of facing the blade portion 231, and a skin contact surface 42 located on the lower side (the other side) in the Z direction (vertical direction: first direction) and capable of contacting the skin S. Furthermore, the comb portion 40 has a pair of side surfaces 43 that connect the opposing surface 41 and the skin contact surface 42 on both sides in the Y direction (width direction: third direction).

[0081] 13, the comb portion 40 has a tapered portion 44 that tapers from a root portion 40b located on the substrate (base) 30 side toward a tip portion 40a when viewed in the Y direction (width direction: third direction). That is, the comb portion 40 has a shape in which the distance from the skin contact surface 42 to the opposing surface 41 gradually decreases (the opposing surface 41 gradually approaches the skin contact surface 42) from the root portion 40b toward the tip portion 40a.

[0082] In this way, by making the comb portion 40 have a tapered portion 44, the cutting height can be changed by shifting the opposing position of the blade portion 231 with respect to the opposing surface 41 in the X direction (front-to-back direction: second direction).

[0083] In this embodiment, a pair of sandwiching walls 70 are formed so as to rise from both sides of the substrate (base) 30 in the Y direction (width direction: third direction) toward the upper side (one side) in the Z direction (vertical direction: first direction). The comb portion 40 is formed so as to extend from the substrate (base) 30 toward the lower side (the other side) in the Z direction (vertical direction: first direction) inside the sandwiching walls 70 in the Y direction (width direction: third direction). This forms a space between the pair of sandwiching walls 70 that is open to the upper side (one side) in the Z direction (vertical direction: first direction).

[0084] Then, the head 20 of the hair clippers 1 is introduced from above into the space formed between the pair of clamping walls 70, so that the head 20 of the hair clippers 1 is clamped by the pair of clamping walls 70 from both sides in the Y direction (width direction: third direction).

[0085] In this embodiment, an engaging protrusion (engaging portion) 74 is formed on each of the inner surfaces 71 of the pair of clamping walls 70 so as to protrude inward in the Y direction (width direction: third direction). Also, grooves 2211 are formed on both sides of the head 20 of the hair clippers 1 in the Y direction (width direction: third direction) so as to open to the attachment 3 side, and engaging recesses (engaged portions) 22111 that can engage with the engaging protrusions (engaging portions) 74 are formed on the back side of each groove 2211.

[0086] When the head 20 of the hair clippers 1 is introduced from above into the space formed between the pair of clamping walls 70, the engaging protrusion (engaging portion) 74 is introduced into the groove 2211 and engages with the engaging recess (engaged portion) 22111 formed on the back side of the groove 2211.

[0087] This allows the attachment 3 to be attached to the head 20 of the hair clipper 1 in a state where relative movement is restricted, and the distance between the blade 231 and the skin contact surface 42 can be maintained at a predetermined constant distance.

[0088] As described above, in this embodiment, the attachment 3 is configured to be detachably attached to the hair clippers 1 by moving the attachment 3 relative to the hair clippers 1 in the Z direction (vertical direction: first direction) to releasably engage the engaging protrusion (engaging portion) 74 with the engaging recess (engaged portion) 22111. In other words, the attachment 3 according to this embodiment is an attachment that can be detachably attached to the hair clippers 1 by moving the attachment 3 relative to the hair clippers 1 having the blade portion 231 in the Z direction (vertical direction: first direction).

[0089] In addition, in this embodiment, by moving the attachment 3 relative to the hair clippers 1 in the Z direction (up and down direction: first direction), the engaging protrusion (engaging portion) 74 can be engaged with the engaging recess (engaged portion) 22111, or the engagement between the engaging protrusion (engaging portion) 74 and the engaging recess (engaged portion) 22111 can be released.

[0090] Then, when the attachment 3 having such a configuration is attached to the head 20 of the hair clippers 1 and the skin contact surface 42 of the attachment 3 is brought into contact with the skin S and slid over the skin S, the hair (hair) H introduced into the space formed between adjacent combs 45 is guided to the blade portion 231 while being styled by the comb 45. Then, when the hair (hair) H guided to the blade portion 231 is cut by the blade portion 231, the hair (hair) H is trimmed to a desired uniform length (the distance between the blade portion 231 and the skin contact surface 42 when the attachment 3 is attached).

[0091] In this embodiment, the attachment 3 is attached to the head 20 of the hair clippers 1 in a state where movement (sliding) in the X direction (front-back direction: second direction) is restricted. Therefore, when using the hair clippers 1 with the attachment 3 attached, it is possible to more reliably prevent the attachment 3 from unintentionally moving in the X direction (front-back direction: second direction), which is the direction in which the cutting height is changed. As a result, when cutting hair (fur) H to a predetermined cutting height, variations in the cutting height are suppressed, and it is possible to more reliably cut hair (fur) H to a desired uniform length.

[0092] Here, in this embodiment, the comb portion 40 includes a first comb portion 50 formed to protrude from the substrate (base) 30 to the front side (one side) in the X direction (front-rear direction: second direction), and a second comb portion 60 formed to protrude from the substrate (base) 30 to the rear side (the other side) in the X direction (front-rear direction: second direction).

[0093] Each of the first comb portion 50 and the second comb portion 60 has the function of guiding the hair (hair) H to the blade portion 231 while styling it.

[0094] Specifically, the first comb portion 50 has a plurality of first combs 51 arranged side by side and spaced apart in the Y direction (width direction: third direction).

[0095] In this embodiment, each first comb 51 is approximately plate-shaped and is connected to the front side (one side) of the substrate (base) 30 in the X direction (front-rear direction: second direction) with the plate thickness direction approximately aligned with the Y direction (width direction: third direction) and protruding to the front side (one side) of the X direction (front-rear direction: second direction).

[0096] By doing so, when cutting the hair H using the first comb portion 50, the hair H can be introduced into the space formed between the adjacent first combs 51, and the introduced hair H is guided to the blade portion 231 while being shaped. Then, the guided hair H is cut by the blade portion 231.

[0097] Each first comb 51 is formed with a first opposing surface 511 located on the upper side (one side) in the Z direction (vertical direction: first direction) and capable of facing the blade portion 231, and a first skin contact surface 512 located on the lower side (the other side) in the Z direction (vertical direction: first direction) and capable of contacting the skin S. Furthermore, each first comb 51 is formed with a pair of first side surfaces 513 that connect the first opposing surface 511 and the first skin contact surface 512 on both sides in the Y direction (width direction: third direction).

[0098] In this embodiment, each first comb 51 has a first tapered portion 514 that tapers from a first root portion 51b located on the substrate (base) 30 side toward a first tip portion 51a when viewed along the Y direction (width direction: third direction). That is, each first comb 51 has a shape in which the distance from the first skin contact surface 512 to the first opposing surface 511 gradually decreases (the first opposing surface 511 gradually approaches the first skin contact surface 512) from the first root portion 51b toward the first tip portion 51a.

[0099] In this way, by making each first comb 51 have a first tapered portion 514, the cutting height can be changed by shifting the opposing position of the blade portion 231 with the first opposing surface 511 in the X direction (front-back direction: second direction).

[0100] Similarly, the second comb portion 60 has a plurality of second combs 61 arranged side by side and spaced apart in the Y direction (width direction: third direction).

[0101] Specifically, the second comb portion 60 has a plurality of second combs 61 arranged side by side and spaced apart in the Y direction (width direction: third direction).

[0102] In this embodiment, each second comb 61 is approximately plate-shaped and is connected to the rear side (other side) of the substrate (base) 30 in the X direction (front-rear direction: second direction) with the plate thickness direction approximately aligned with the Y direction (width direction: third direction) and protruding to the rear side (other side) in the X direction (front-rear direction: second direction).

[0103] By doing so, when cutting the hair H using the second comb portion 60, the hair H can be introduced into the space formed between the adjacent second combs 61, and the introduced hair H is guided to the blade portion 231 while being shaped. Then, the guided hair H is cut by the blade portion 231.

[0104] Each second comb 61 is formed with a second opposing surface 611 located on the upper side (one side) in the Z direction (vertical direction: first direction) and capable of facing the blade portion 231, and a second skin contact surface 612 located on the lower side (the other side) in the Z direction (vertical direction: first direction) and capable of contacting the skin S. Furthermore, each second comb 61 is formed with a pair of second side surfaces 613 that connect the second opposing surface 611 and the second skin contact surface 612 on both sides in the Y direction (width direction: third direction).

[0105] In this embodiment, each second comb 61 has a second tapered portion 614 that tapers from a second root portion 61b located on the substrate (base) 30 side toward a second tip portion 61a when viewed along the Y direction (width direction: third direction). That is, each second comb 61 has a shape in which the distance from the second skin contact surface 612 to the second opposing surface 611 gradually decreases (the second opposing surface 611 gradually approaches the second skin contact surface 612) from the second root portion 61b toward the second tip portion 61a.

[0106] In this way, by making each second comb 61 have the second tapered portion 614, the cutting height can be changed by shifting the opposing position of the blade portion 231 with the second opposing surface 611 in the X direction (front-back direction: second direction).

[0107] Therefore, in this embodiment, the first opposing surface 511 formed on each first comb 51 and the second opposing surface 611 formed on each second comb 61 are formed on the comb portion 40 so as to be located on the upper side (one side) in the Z direction (up and down direction: first direction), and form opposing surfaces 41 that can face the blade portion 231.

[0108] In addition, the first skin contact surface 512 formed on each first comb 51 and the second skin contact surface 612 formed on each second comb 61 are formed on the comb portion 40 so as to be located on the lower side (other side) in the Z direction (up and down direction: first direction), thereby forming a skin contact surface 42 that can come into contact with the skin S.

[0109] The outer first side surface 513 of the first comb 51 located outermost in the Y direction (width direction: third direction) and the outer second side surface 613 of the second comb 61 located outermost in the Y direction (width direction: third direction) form a pair of side surfaces 43 of the comb portion 40 formed to connect the opposing surface 41 and the skin contact surface 42 on both sides in the Y direction (width direction: third direction).

[0110] Furthermore, in this embodiment, the first tapered portion 514 formed on each first comb 51 and the second tapered portion 614 formed on each second comb 61 form the tapered portion 44 of the comb portion 40 that tapers from the root portion 40b located on the substrate (base) 30 side toward the tip portion 40a when viewed along the Y direction (width direction: third direction).

[0111] In this embodiment, the number of first combs 51 and the number of second combs 61 are the same (7). Corresponding first combs 51 and second combs 61 are arranged at the same position in the Y direction (width direction: third direction). That is, corresponding first combs 51 and second combs 61 are formed to be positioned on the same straight line along the X direction (front-rear direction: second direction). Therefore, in this embodiment, the first combs 51 and second combs 61 connected to each other constitute one comb 45.

[0112] However, when the comb portion 40 includes the first comb portions 50 and the second comb portions 60, the above-described configuration is not necessary, and it is also possible to make the number of first combs 51 different from the number of second combs 61. It is also possible to form the first combs 51 and the second combs 61 in the same number, with the corresponding first combs 51 and second combs 61 shifted in the Y direction (width direction: third direction).

[0113] Furthermore, in this embodiment, the engaging protrusion (engaging portion) 74 includes a first engaging protrusion (first engaging portion) 741 that engages with the engaging recess (engaged portion) 22111 when the first comb portion 50 is used, and a second engaging protrusion (second engaging portion) 742 that engages with the engaging recess (engaged portion) 22111 when the second comb portion 60 is used. The first engaging protrusion (first engaging portion) 741 and the second engaging protrusion (second engaging portion) 742 are arranged side by side and spaced apart in the X direction (front-rear direction: second direction). Specifically, the first engaging protrusion (first engaging portion) 741 is formed at the front of the sandwiching wall 70 in the X direction (front-rear direction: second direction), and the second engaging protrusion (second engaging portion) 742 is formed at the rear of the sandwiching wall 70 in the X direction (front-rear direction: second direction). Thus, in this embodiment, the clamping wall 70 is provided with a plurality of engaging protrusions (engaging portions) 74 spaced apart in the X direction (front-to-back direction: second direction), which can be releasably engaged with the engaging recesses (engaged portions) 22111 formed in the hair clippers 1 by moving them relatively in the Z direction (up-down direction: first direction).

[0114] When engaging the first engaging protrusion (first engaging portion) 741 with the engaging recess (engaged portion) 22111, the head 20 of the hair clippers 1 is introduced from above into the space formed between the pair of clamping walls 70 with the tip of the blade portion 231 facing forward (one side) in the X direction (front-to-back direction: second direction).

[0115] On the other hand, when engaging the second engaging protrusion (second engaging portion) 742 with the engaging recess (engaged portion) 22111, the head 20 of the hair clippers 1 is introduced from above into the space formed between the pair of clamping walls 70 with the tip of the blade portion 231 facing rearward (the other side) in the X direction (front-to-back direction: second direction).

[0116] As described above, in this embodiment, the attachment 3 includes the first comb portion 50 and the second comb portion 60, and when attaching the hair clippers 1 to the attachment 3, the orientation of the blade portion 231 is changed. By changing the orientation of the blade portion 231, it is possible to select which comb portion to use, the first comb portion 50 or the second comb portion 60. This allows the cutting height to be adjusted for each comb portion, further increasing the variety of cutting heights.

[0117] In this embodiment, the cutting height when the first comb portion 50 is used is different from the cutting height when the second comb portion 60 is used. This makes it possible to selectively change the cutting height by engaging one engaging portion selected from the multiple engaging portions (first engaging protrusion 741 and second engaging protrusion 742) that are arranged side by side and spaced apart in the X direction (front-rear direction: second direction) with the engaging recess (engaged portion) 22111.

[0118] Specifically, as shown in FIG. 13 , the length L1 of the first comb portion 50 on the substrate (base) 30 side in the Z direction (vertical direction: first direction) is different from the length L2 of the second comb portion 60 on the substrate (base) 30 side in the Z direction (vertical direction: first direction). In this embodiment, the length L2 is made shorter than the length L1. That is, the thickness of the second comb portion 60 on the substrate (base) 30 side is made thinner than the thickness of the first comb portion 50 on the substrate (base) 30 side. This makes it easier to set the mowing height when the first comb portion 50 and the mowing height when the second comb portion 60 are used to different values.

[0119] If the length L1 of the first comb portion 50 on the substrate (base) 30 side in the Z direction (vertical direction: first direction) and the length L2 of the second comb portion 60 on the substrate (base) 30 side are made different from each other, the shapes of the first comb portion 50 and the second comb portion 60 will be different, making it easier to distinguish between the first comb portion 50 and the second comb portion 60. Therefore, when attaching the attachment 3 to the head 20 of the hair clippers 1, it becomes easier to distinguish which comb portion to use, and the usability of the attachment 3 can be further improved.

[0120] 9, the engaging protrusions (engaging portions) 74 have a selective engaging group 75. Here, the selective engaging group 75 refers to a group (assembly) of engaging portions made up of two or more engaging protrusions (engaging portions) 74 that can be selectively engaged with the engaging recesses (engaged portions) 22111 when the hair clippers 1 are arranged so that the blade portions 231 are oriented in the same direction, and that can vary the distance (cutting height) from the skin contact surface 42 to the blade portions 231 when engaged with the engaging recesses (engaged portions) 22111.

[0121] That is, the attachment 3 has a selective engagement group 75 made up of two or more engagement protrusions (engagement portions) 74 that can be selectively engaged with the engagement recesses (engaged portions) 22111 when the clippers 1 are positioned so that the blade portions 231 are oriented in the same direction. The selective engagement group 75 includes at least one engagement protrusion (engagement portion) 74 that can change the distance (cutting height) from the skin contact surface 42 to the blade portions 231 when engaged with the engagement recesses (engaged portions) 22111.

[0122] In this embodiment, there are two (plural: at least two) first engagement protrusions (first engagement portions) 741 used for using the first comb portion (one comb portion) 50. The two first engagement protrusions (first engagement portions) 741 are arranged side by side at a first pitch P1 in the front of the clamping wall 70 in the X direction (front-rear direction: second direction). This allows the head 20 of the hair clippers 1, with the tip of the blade portion 231 facing forward (one side) in the X direction (front-rear direction: second direction), to be attached to the attachment 3 with a shift in the X direction (front-rear direction: second direction). In other words, the relative position of the head 20 of the hair clippers 1 with respect to the attachment 3 when one first engagement protrusion (first engagement portion) 741 is engaged with the engagement recess (engaged portion) 22111 and the relative position of the head 20 of the hair clippers 1 with respect to the attachment 3 when the other first engagement protrusion (first engagement portion) 741 is engaged with the engagement recess (engaged portion) 22111 are shifted in the X direction (front-to-back direction: second direction) by a first pitch P1.

[0123] At this time, since the first comb 51 of the first comb portion 50 has a shape having a first tapered portion 514, the cutting height will be different when one first engaging protrusion (first engaging portion) 741 is engaged with the engaging recess (engaged portion) 22111 and when the other first engaging protrusion (first engaging portion) 741 is engaged with the engaging recess (engaged portion) 22111.

[0124] In this embodiment, as shown in Figures 19 and 22, the distance (cutting height) H1 from the first skin contact surface 512 to the blade portion 231 when the first engaging protrusion (first engaging portion) 741 located on the first tip portion 51a side of the two first engaging protrusions (first engaging portions) 741 is engaged with the engaging recess (engaged portion) 22111 is greater than the distance (cutting height) H2 from the first skin contact surface 512 to the blade portion 231 when the first engaging protrusion (first engaging portion) 741 located on the first root portion 51b side is engaged with the engaging recess (engaged portion) 22111.

[0125] As described above, in this embodiment, the selective engagement group 75 has a first selective engagement group 751 which is composed of two or more first engagement protrusions (first engagement portions) 741 that can be selectively engaged with the engagement recess (engaged portion) 22111 when the hair clippers 1 is positioned so that the blade portion 231 faces the front (one side) in the X direction (front-to-back direction: second direction), and which can vary the distance from the first skin contact surface 512 to the blade portion 231 when engaged with the engagement recess (engaged portion) 22111.

[0126] Therefore, the attachment 3 according to this embodiment is configured so that two (or more) different cutting heights can be set for the first comb portion 50, which is a single comb portion, by changing the location where the head 20 of the hair clippers 1 is attached. In other words, the attachment 3 is configured so that the cutting height of the first comb portion (one comb portion) 50 can be selectively changed without sliding the attachment 3 in the X direction (front-back direction: second direction) relative to the head 20 of the hair clippers 1.

[0127] At this time, the attachment 3 is attached to the head 20 of the hair clippers 1 in a state where movement (sliding) in the X direction (front-to-back direction: second direction) is restricted. Therefore, when using the hair clippers 1 with the attachment 3 attached and set to the desired cutting height, it is possible to more reliably prevent the attachment 3 from unintentionally moving in the X direction (front-to-back direction: second direction), which is the direction in which the cutting height is changed. As a result, when cutting hair H to a predetermined cutting height using the first comb part 50, variations in the cutting height are suppressed, and it is possible to more reliably cut the hair H to a desired uniform length.

[0128] Furthermore, in this embodiment, there are three (plural: at least two) second engagement protrusions (second engagement portions) 742 used for using the second comb portion (one comb portion) 60. As shown in FIG. 12, the three second engagement protrusions (second engagement portions) 742 are arranged side by side at a second pitch P2 at the rear of the clamping wall 70 in the X direction (front-rear direction: second direction) and spaced apart at approximately equal intervals. This allows the head 20 of the hair clippers 1, with the tip of the blade 231 facing rearward (the other side) in the X direction (front-rear direction: second direction), to be attached to the attachment 3 while being shifted in the X direction (front-rear direction: second direction). In other words, the relative position of the head 20 of the hair clippers 1 to the attachment 3 when the second engaging protrusion (second engaging portion) 742 on the tip side is engaged with the engaging recess (engaged portion) 22111, the relative position of the head 20 of the hair clippers 1 to the attachment 3 when the second engaging protrusion (second engaging portion) 742 on the center side is engaged with the engaging recess (engaged portion) 22111, and the relative position of the head 20 of the hair clippers 1 to the attachment 3 when the second engaging protrusion (second engaging portion) 742 on the base side is engaged with the engaging recess (engaged portion) 22111 are all shifted by a second pitch P2 in the X direction (front-to-back direction: second direction).

[0129] At this time, since the second comb 61 of the second comb portion 60 has a shape having a second tapered portion 614, the cutting height will differ depending on whether the second engaging protrusion (second engaging portion) 742 on the tip side is engaged with the engaging recess (engaged portion) 22111, whether the second engaging protrusion (second engaging portion) 742 on the central side is engaged with the engaging recess (engaged portion) 22111, or whether the second engaging protrusion (second engaging portion) 742 on the base side is engaged with the engaging recess (engaged portion) 22111.

[0130] In this embodiment, as shown in Figures 25 and 28, the distance (cutting height) H4 from the second skin contact surface 612 to the blade portion 231 when the second engaging protrusion (second engaging portion) 742 located on the central side is engaged with the engaging recess (engaged portion) 22111 is greater than the distance (cutting height) H3 from the second skin contact surface 612 to the blade portion 231 when the second engaging protrusion (second engaging portion) 742 located on the second tip portion 61a side of the three second engaging protrusions (second engaging portions) 742 is engaged with the engaging recess (engaged portion) 22111.

[0131] Furthermore, as shown in Figures 28 and 31, the distance (cutting height) H5 from the second skin contact surface 612 to the blade portion 231 when the second engaging protrusion (second engaging portion) 742 located on the second root portion 61b side is engaged with the engaging recess (engaged portion) 22111 is greater than the distance (cutting height) H4 from the second skin contact surface 612 to the blade portion 231 when the second engaging protrusion (second engaging portion) 742 located on the central side of the three second engaging protrusions (second engaging portions) 742 is engaged with the engaging recess (engaged portion) 22111.

[0132] Thus, in this embodiment, the selective engagement group 75 has a second selective engagement group 752 which is composed of two or more second engagement protrusions (second engagement portions) 742 that can be selectively engaged with the engagement recess (engaged portion) 22111 when the hair clippers 1 is positioned so that the blade portion 231 faces the rear (other side) in the X direction (front-to-back direction: second direction), and which can vary the distance from the second skin contact surface 612 to the blade portion 231 when engaged with the engagement recess (engaged portion) 22111.

[0133] Therefore, the attachment 3 according to this embodiment is configured so that three (two or more) different cutting heights can be set for the second comb portion 60, which is a single comb portion, by changing the location where the head 20 of the hair clippers 1 is attached. In other words, the attachment 3 is configured so that the cutting height of the second comb portion (one comb portion) 60 can be selectively changed without sliding the attachment 3 in the X direction (front-back direction: second direction) relative to the head 20 of the hair clippers 1.

[0134] At this time, the attachment 3 is attached to the head 20 of the hair clippers 1 in a state where movement (sliding) in the X direction (front-to-back direction: second direction) is restricted. Therefore, when using the hair clippers 1 with the attachment 3 attached and set to the desired cutting height, it is possible to more reliably prevent the attachment 3 from unintentionally moving in the X direction (front-to-back direction: second direction), which is the direction in which the cutting height is changed. As a result, when cutting hair H to a predetermined cutting height using the second comb part 60, variations in the cutting height are suppressed, and it is possible to more reliably cut the hair H to a desired uniform length.

[0135] In this embodiment, the cutting heights that can be achieved when using attachment 3 are H2, H1, H5, H4, and H3 in that order, and by using attachment 3, the cutting height can be adjusted in five stages from H1 to H5.

[0136] In this way, in this embodiment, the clippers 1 can be attached to the attachment 3 by changing the orientation of the blade portion 231, and the cutting height of each comb portion can be adjusted in multiple stages.

[0137] Furthermore, in this embodiment, all five engaging protrusions (engaging portions) 74 are formed on the clamping wall 70 so that the distance L to the opposing surface 41 is approximately the same. By doing so, even when the engaging recess (engaged portion) 22111 is engaged with any one of the five engaging protrusions (engaging portions) 74, the distance from the blade portion 231 to the opposing surface 41 is approximately the same.

[0138] In this embodiment, the positions (distance L) of the five engaging protrusions (engaging portions) 74 are set so that the gap between the blade portion 231 and the opposing surface 41 is minimized.

[0139] Specifically, a tip side step 5111 and a base side step 5112 are formed on the first opposing surface 511. When the engaging recess (engaged portion) 22111 is engaged with the first engaging protrusion (first engaging portion) 741 located on the first tip portion 51a side, the blade portion 231 is placed on the tip side step 5111. When the engaging recess (engaged portion) 22111 is engaged with the first engaging protrusion (first engaging portion) 741 located on the first base portion 51b side, the blade portion 231 is placed on the base side step 5112.

[0140] Similarly, the second opposing surface 611 is formed with a tip-side step 6111, a central step 6112, and a base-side step 6113. When the engaging recess (engaged portion) 22111 is engaged with the second engaging protrusion (second engaging portion) 742 located on the second tip portion 61a side, the blade portion 231 is placed on the tip-side step 6111. When the engaging recess (engaged portion) 22111 is engaged with the second engaging protrusion (second engaging portion) 742 located on the center side, the blade portion 231 is placed on the central step 6112. When the engaging recess (engaged portion) 22111 is engaged with the second engaging protrusion (second engaging portion) 742 located on the second base portion 61b side, the blade portion 231 is placed on the base-side step 6113.

[0141] In this way, by minimizing the gap between the blade portion 231 and the opposing surface 41, it is possible to more reliably prevent hair debris from entering the gap between the blade portion 231 and the opposing surface 41 when cutting the hair (hair) H. Furthermore, by preventing hair debris from entering the gap between the blade portion 231 and the opposing surface 41, it is possible to prevent a decrease in the ability of the hair clippers 1 to cut the hair (hair) H, and it becomes possible to cut the hair (hair) H more efficiently and accurately.

[0142] In this embodiment, all of the five engaging protrusions (engaging portions) 74 are formed on the sandwiching wall 70 so that the distances L to the opposing surface 41 are approximately the same, and therefore the engaging protrusions (engaging portions) 74 are formed at various height positions (positions in the first direction) on the sandwiching wall 70. That is, on the sandwiching wall 70, there are engaging protrusions (engaging portions) 74 formed at different height positions, such as the engaging protrusions (engaging portions) 74 formed on the tip portion 70a side which is located away from the substrate (base) 30, and the engaging protrusions (engaging portions) 74 formed on the root portion 70b side which is located closer to the substrate (base) 30.

[0143] The tip portion 70a of the clamping wall 70 is a portion that bends relatively large when the attachment 3 is attached to or detached from the hair clippers 1, while the base portion 70b of the clamping wall 70 is a portion that bends relatively small when the attachment 3 is attached to or detached from the hair clippers 1.

[0144] Therefore, if the five engaging protrusions (engaging portions) 74 have the same protrusion amounts W1 to W5 from the inner surface 71 of the clamping wall 70, the force required to attach and detach the attachment 3 will vary depending on the position where the hair clippers 1 are attached.

[0145] Therefore, in this embodiment, the protrusion amounts W1 to W5 of the five engaging protrusions (engaging portions) 74 from the inner surface 71 of the sandwiching wall 70 are made to differ based on the distance from the substrate (base) 30. In other words, the protrusion amounts from the inner surface 71 of the sandwiching wall 70 are set depending on the parts of the sandwiching wall 70 where the engaging protrusions (engaging portions) 74 are formed.

[0146] Specifically, as shown in Figures 9 and 12, the protrusion amount of the engaging protrusion (engagement portion) 74 formed on the base portion 70b of the clamping wall 70, which is a portion that experiences a relatively small amount of deflection when attaching or detaching the attachment 3 to the hair clippers 1, is made small, and the protrusion amount of the engaging protrusion (engagement portion) 74 formed on the tip portion 70a of the clamping wall 70, which is a portion that experiences a relatively large amount of deflection, is made large.

[0147] This makes it possible to make the force required when attaching and detaching the attachment 3 more uniform.

[0148] 7, in this embodiment, a connecting protrusion 76 connected to the engaging protrusion (engaging portion) 74 is formed on the sandwiching wall 70. The connecting protrusion 76 is formed continuously through an upper (one side) end face 73 in the Z direction (vertical direction: first direction) of the sandwiching wall 70 to the outer surface 72. In this manner, in this embodiment, the connecting protrusion 76 is provided so as to extend at least to the upper (one side) end face 73 in the Z direction (vertical direction: first direction) of the sandwiching wall 70.

[0149] This makes it easier to visually check the position of the engaging protrusion (engaging portion) 74 that engages when achieving the desired cutting height, thereby further improving the ease of attaching the attachment 3 to the hair clippers 1.

[0150] Furthermore, if the connecting protrusion 76 connected to the engaging protrusion (engaging portion) 74 is formed up to the upper (one side) end face 73 in the Z direction (up and down direction: first direction) of the clamping wall 70, this connecting protrusion 76 can also function as a guide when engaging the engaging recess (engaged portion) 22111 of the hair clippers 1 with the engaging protrusion (engaging portion) 74.

[0151] Furthermore, in this embodiment, as shown in FIG. 7, the inner surface 71 of the clamping wall 70 is formed with a rib 77 that interferes with the hair clippers 1 when the hair clippers 1 are positioned in an incorrect position.

[0152] This makes it possible to prevent the attachment 3 from being attached incorrectly to the hair clippers 1. This makes it possible to more reliably prevent the hair clippers 1 from being attached to the attachment 3 in an incorrect state (for example, in a state where the hair clippers 1 are tilted diagonally relative to the attachment 3, or in a state where the blades 231 are facing in the wrong direction, etc.).

[0153] The attachment 3 according to this embodiment is a resin molded product 100 that is integrally formed using an insulating synthetic resin material.

[0154] In this way, when the attachment 3 is made of the resin molded product 100, it is preferable to increase the thickness of the comb 45 in order to ensure the strength of the comb portion 40.

[0155] However, when forming the attachment 3 using a synthetic resin material, the thicker the comb 45, the more difficult it becomes to mold the comb portion 40. Also, if the thickness of the comb 45 is increased, warping may occur when the resin molded product 100 is manufactured.

[0156] Therefore, in this embodiment, even if the thickness of the comb 45 is increased, it is possible to more reliably prevent the occurrence of warping.

[0157] 13, the substrate (base) 30 includes a substantially plate-shaped base body 31 having an upper surface 311 and a lower surface 312, and extending substantially horizontally with a thickness T1 substantially aligned with the Z direction (vertical direction: first direction), and a pair of thin plates (crossing wall portions) 32 connected to both ends of the base body 31 in the X direction (front-to-back direction: second direction) and extending substantially vertically with a thickness T2 substantially aligned with the X direction (front-to-back direction: second direction), which is a direction intersecting the extension direction of the base body 31. In this manner, in this embodiment, the thickness T2 of the pair of thin plates (crossing wall portions) 32 is the thickness in the X direction (front-to-back direction: second direction), and the thickness T1 of the base body 31 is the thickness in the Z direction (vertical direction: first direction).

[0158] In this embodiment, the pair of thin plates (cross wall portions) 32 are formed to protrude downward from the lower surface 312 of the base body 31. All the combs 45 are connected by the thin plates (cross wall portions) 32. In this manner, in this embodiment, there is at least one thin wall (cross wall portion) 32 extending vertically from the base body 31 to connect the combs 45 to each other.

[0159] This makes it possible to more reliably prevent warpage from occurring when the resin molded product 100 is manufactured.

[0160] In this embodiment, the thin plate (intersecting wall portion) 32 is formed so as to protrude downward (toward the extending side of the combs 45) from the lower surface 312 of the base body 31. Therefore, when the resin molded product 100 is manufactured, the thin plate (intersecting wall portion) 32 prevents warpage from occurring in a direction that shortens the distance between the combs 45.

[0161] Furthermore, by suppressing warping in the direction that shortens the distance between the combs 45, it is possible to prevent the tip end 70a of the clamping wall 70 from opening outward in the Y direction (width direction: third direction). This prevents the engagement force between the engaging protrusion (engaging portion) 74 and the engaging recess (engaged portion) 22111 from weakening, making it possible to more reliably attach the attachment 3 to the hair clippers 1.

[0162] When forming such a thin plate (intersecting wall portion) 32, it is preferable that the plate thickness T2 is thinner than the plate thickness T1. This allows the thin plate (intersecting wall portion) 32 to solidify before the other portions (base body 31, comb portion 40) when manufacturing the resin molded product 100, thereby more reliably suppressing the occurrence of warpage.

[0163] In this embodiment, the plate thickness T2 is set to 1 / 3 to 1 / 2 of the plate thickness T1, which allows the solidification of the thin plate (intersection wall portion) 32 to be accelerated while maintaining the strength of the thin plate (intersection wall portion) 32.

[0164] Furthermore, by providing the thin plate (intersecting wall portion) 32, the strength of the attachment 3 can be further improved, and therefore the shape stability of the attachment 3 can be further improved.

[0165] Furthermore, if the attachment 3 is formed using a synthetic resin material, unevenness formed during manufacturing by resin molding (such as unevenness formed to maintain a uniform thickness of the comb portion 40 of the attachment 3, or unevenness formed to prevent sink marks) may appear on the exterior, which may result in a poor appearance.

[0166] Therefore, in this embodiment, an extension wall 80 is formed on the substrate (base) 30 so as to extend from the substrate (base) 30 downward (to the other side) in the Z direction (vertical direction: first direction), and this extension wall 80 is connected to the clamping wall 70.

[0167] In this way, the extension wall 80 can hide any irregularities that are formed when the attachment is manufactured by resin molding (such as irregularities formed to keep the thickness of the comb portion 40 of the attachment 3 uniform, or irregularities provided to prevent sink marks), thereby further improving the appearance of the attachment 3.

[0168] At this time, by connecting the clamping wall 70 and the extension wall 80 with a small curvature, the side of the attachment 3 approaches a flatter surface, and the side of the attachment 3 is prevented from bulging out too much.

[0169] In addition, in this embodiment, the extension wall 80 has a lower end surface that is similar in shape to the skin contact surface 42 of the comb portion 40 in a side view, and this lower end surface is formed to be located higher than the skin contact surface 42 of the comb portion 40. Therefore, in this embodiment, the lower end surface of the extension wall 80 serves as a skin-facing surface 81 that faces the skin S across a space when the skin contact surface 42 of the comb portion 40 is in contact with the skin S.

[0170] Furthermore, in this embodiment, the extension wall 80 has a side surface 82, and this side surface 82 has a side portion 821 with a relatively small curvature and connecting portions 822 with a relatively large curvature that are connected to the front and rear of the side portion 821. The connecting portions 822 located at the front and rear are connected to the first tip portion 51a of the first comb 51 located at the outermost position and the second tip portion 61a of the second comb 61 located at the outermost position, respectively.

[0171] In this way, the comb-shaped extension wall 80 serves as a dummy comb.

[0172] 8 and 11, in this embodiment, a recess 90 that opens downward (to the other side) in the Z direction (vertical direction: first direction) is formed between the extension wall 80 and the comb portion 40. That is, an elongated recess 90 is formed in the X direction (front-rear direction: second direction) between the extension wall 80 connected at the front and rear and the outermost comb 45.

[0173] This allows short hairs to enter the recess 90 formed between the extension wall 80 and the comb portion 40 when using the hair clippers 1 with the attachment 3 attached. This reduces the resistance that occurs when the attachment 3 is used by contacting it with the skin S. This further improves the ease of use of the attachment 3.

[0174] Furthermore, by allowing short hairs to enter the recess 90 between the extension wall 80 and the comb portion 40, when using the hair clippers 1 with the attachment 3 attached, the hair (hair) H is prevented from being pulled by the attachment 3 in a crushed state, thereby preventing damage to the hair (hair) H from the attachment 3.

[0175] 14 to 16, in this embodiment, the skin contact surface 42 of the comb part 40 is textured to form an uneven textured portion (uneven portion) 421. This reduces the frictional force generated between the skin S and the skin contact surface 42, further improving the smoothness of the skin contact surface 42 on the skin S, and reduces the resistance felt when using the attachment 3.

[0176] The textured portion (uneven portion) 421 can be formed by applying a physical surface treatment such as etching or sandblasting to the surface of a mold and then transferring that surface to the attachment 3, a process known as textured processing. In this case, it is preferable that the arithmetic mean roughness (Ra) of the skin contact surface 42 be 1.0 μm to 4.50 μm. This further improves the comfort of using the attachment 3.

[0177] In this embodiment, a first textured portion (first uneven portion) 5121 is formed on the first skin contact surface 512 of the first comb 51, and a second textured portion (second uneven portion) 6121 is formed on the second skin contact surface 612 of the second comb 61. Furthermore, a lower end surface 4511 connecting the first skin contact surface 512 and the second skin contact surface 612 is also textured, and a textured portion (uneven portion) 45111 is formed on the lower end surface 4511. That is, in this embodiment, the lower end surface 451 of the comb 45 has the first skin contact surface 512, the second skin contact surface 612, and the lower end surface 4511 connecting the first skin contact surface 512 and the second skin contact surface 612, and the textured portion (uneven portion) 421 is formed over the entire lower end surface 451 of the comb 45.

[0178] In this embodiment, the surface roughness of the side surface 452 of each comb 45 is set to be smaller than the surface roughness of the bottom end surface 451 of the comb 45. In other words, the side surface 452 of each comb 45 is set to be smoother than the bottom end surface 451.

[0179] This makes it possible to further improve the introduction of hair (hair) H into the space formed between the adjacent combs 45.

[0180] Next, an example of how to use the attachment 3 configured as above when attached to the head 20 will be described.

[0181] First, the head 20 is attached to the body 10, and the power transmission unit 241 is attached to the drive shaft 16. Then, any one of the five engagement protrusions (engagement portions) 74 is engaged with the engagement recess (engaged portion) 22111 of the head 20, and the attachment 3 is attached to the head 20. Note that the attachment of the head 20 to the body 10 and the attachment of the attachment 3 to the head 20 may be performed in any order.

[0182] In this state, the power switch 123 is pressed to drive the rotary motor 15, thereby rotating the drive shaft 16.

[0183] In this way, the rotation of the drive shaft 16 is transmitted to the power transmission unit 241, and the power transmission unit 241 rotates together with the drive shaft 16. At this time, the operating shaft 242 attached to the power transmission unit 241, the base 2441 attached to the operating shaft 242, and the eccentric shaft 2442 attached to the base 2441 also rotate together with the power transmission unit 241. Then, as the eccentric shaft 2442 rotates, the link 2443 attached to the eccentric shaft 2442 moves back and forth in a linear motion in the width direction.

[0184] In this way, when the link 2443 makes a linear reciprocating motion in the width direction, only the force in the width direction is transmitted from the link 2443 to the connection part 2351, and the holding plate 235 makes a linear reciprocating motion in the width direction. At this time, the movable plate 233 supported by the holding plate 235 also makes a linear reciprocating motion in the width direction, and the movable blade 2331 provided on the movable plate 233 makes a linear reciprocating motion (slides) in the width direction while abutting against the fixed blade 2321.

[0185] In this way, the movable blade 2331 and the fixed blade 2321 cooperate to cut the body hair (hair) H at a desired cutting height.

[0186] Instead of using one type of attachment 3, multiple types of attachments 3 that can achieve different cutting heights may be provided so that the desired attachment 3 can be selectively attached to the hair clippers 1.

[0187] [Modifications of attachment configuration] Next, a modified example of the attachment 3 will be described.

[0188] 32 and 33 show an example of an attachment 3 according to a first modified example.

[0189] 32 and 33, the attachment 3 according to the first modified example is configured so that a pair of thin plates (intersecting wall portions) 32 are formed in a state where they protrude above the upper surface 311 of the base body 31. All of the combs 45 are connected by the thin plates (intersecting wall portions) 32.

[0190] In this way, by forming the pair of thin plates (intersecting wall portions) 32 so that they protrude above the upper surface 311 of the base body 31, when manufacturing the resin molded product 100, these thin plates (intersecting wall portions) 32 will prevent warping from occurring in the direction that shortens the distance between the clamping walls 70.

[0191] Furthermore, by suppressing the occurrence of warping in the direction in which the distance between the clamping walls 70 becomes shorter, it becomes possible to prevent the tip side (skin contact surface 42 side) of the comb 45 from opening outward in the Y direction (width direction: third direction).

[0192] Therefore, by using the attachment 3 shown in FIGS. 32 and 33, it is possible to more reliably prevent warpage from occurring when the resin molded product 100 is manufactured.

[0193] The pair of thin plates (intersecting wall portions) 32 may be formed so as to protrude upward from the upper surface 311 of the base body 31 and also protrude downward from the lower surface 312 of the base body 31. In this way, it becomes possible to more reliably prevent warpage from occurring when the resin molded product 100 is manufactured.

[0194] 34 and 35 show an example of an attachment 3 according to a second modified example.

[0195] As shown in FIGS. 34 and 35, the attachment 3 according to the second modified example is formed by assembling two or more members.

[0196] Specifically, the attachment 3 of the second modified example is a resin assembly 110 formed by assembling a comb member 111 that becomes the comb portion 40 and a holding member 112 that becomes the clamping wall 70 and extension wall 80 that hold the comb portion 40.

[0197] In this way, by assembling two or more members to form the attachment 3, it becomes possible to form the comb portion 40 from a more optimal material, and to form the clamping wall 70 from a more optimal material. In other words, it becomes possible to manufacture the attachment 3 using materials that are optimal for each function.

[0198] For example, the retaining member 112 (the clamping wall 70 and the extension wall 80) can be formed from polyoxymethylene (POM), which has relatively high abrasion resistance, and the comb member 111 (the base 30 and the comb portion 40) can be formed from acrylonitrile-butadiene-styrene copolymer (ABS resin), which is relatively resistant to deformation.

[0199] This arrangement increases the strength of the comb portion 40 and also improves the ease of attaching and detaching the attachment 3 to the hair clippers 1.

[0200] At this time, it is preferable that the resin assembly 110 be formed by assembling the components (comb component 111, holding component 112, etc.) in a removable state.

[0201] In this way, if the resin assembly 110 is assembled in a state where each component (comb component 111, holding component 112, etc.) can be removed, it becomes possible to replace the comb component 111 with a different cutting height by attaching it to the holding component 112. This further increases the variety of cutting heights available for the attachment 3.

[0202] 36 and 37 show an example of an attachment 3 according to a third modified example.

[0203] As shown in Figures 36 and 37, the attachment 3 of the third modified example is an insert-molded product 130 that integrates a metallic comb portion 40 as an insert member 140 and a substrate (base) 30 as a filling resin 150.

[0204] In this way, the comb 45 of the attachment 3 can be made thinner to improve hair styling performance, while the strength of the comb portion 40 can be improved.

[0205] (Addendum) The above description of the embodiments discloses the following techniques.

[0206] (Technology 1) An attachment for a cutting device that can be detachably attached to a cutting device having a blade portion, the attachment having a base, an opposing surface located on one side in a first direction and capable of facing the blade portion, and a skin contact surface located on the other side in the first direction and capable of contacting the skin, the attachment also comprising: a comb portion provided on the base and protruding in a second direction intersecting with the first direction; and clamping walls provided on the base and capable of clamping the cutting device from both sides in a third direction intersecting with the first direction and the second direction, the skin contact surface having an uneven portion formed thereon.

[0207] By providing the skin contact surface with irregularities in this way, the contact area between the skin contact surface and the skin can be reduced, and the frictional force generated between the skin contact surface and the skin can be reduced, thereby further improving the slipperiness of the skin contact surface on the skin.

[0208] (Technology 2) The attachment for a cutting device according to Technology 1, wherein the uneven portion is a embossed portion formed by applying a embossing process to the skin contact surface.

[0209] In this way, by forming the unevenness on the skin-contacting surface by texturing, it becomes possible to form the unevenness on the skin-contacting surface more easily. Furthermore, by forming the texturing on the skin-contacting surface, it becomes possible to form the fine unevenness almost uniformly over the entire skin-contacting surface, which more reliably improves the slipperiness of the skin-contacting surface on the skin.

[0210] (Technology 3) The attachment for a cutting device according to Technology 1 or Technology 2, wherein the surface roughness of the side surface of the comb portion is smaller than the surface roughness of the skin contact surface.

[0211] This prevents the sides of the comb from interfering with the introduction of hair into the blade section, which results in the hair passing through the blade section more easily and more efficiently, allowing the hair to be trimmed to the desired uniform length.

[0212] (Technology 4) An attachment for a cutting device described in any one of Technologies 1 to 3, wherein the clamping wall is formed to extend from the base toward one side in the first direction, the comb portion is formed to extend from the base toward the other side in the first direction, inside the clamping wall in the third direction, and an extension wall is formed on the base to extend from the base toward the other side in the first direction, and the extension wall is connected to the clamping wall.

[0213] In this way, for example, the extension wall can hide irregularities that are formed when the attachment is manufactured by resin molding (irregularities formed to keep the attachment's thickness uniform, irregularities provided to prevent sink marks, etc.), which can further improve the appearance of the attachment.

[0214] (Technical Aspect 5) The attachment for the cutting device according to Technical Aspect 4, wherein a recessed portion that opens to the other side in the first direction is formed between the extension wall and the comb portion.

[0215] This allows short hairs to get into the recess between the extension wall and the comb when using the cutting device with the attachment attached, thereby reducing the resistance that occurs when the attachment is used in contact with the skin, and improving the ease of use of the attachment.

[0216] Furthermore, by allowing short hairs to enter the recess between the extension wall and the comb portion, the impact of the attachment on the hair can be reduced compared to when the attachment is slid over the skin while the hair is crushed by the wall between the extension wall and the comb portion. For example, when the attachment is slid over the skin while the hair is crushed by the wall between the extension wall and the comb portion, the crushed hair may be pulled by the attachment, causing damage to the hair. However, by allowing the hairs to enter the recess between the extension wall and the comb portion, the hair is prevented from being pulled by the attachment, thereby further reducing damage to the hair caused by the attachment.

[0217] (Technology 6) A cutting device to which the attachment for a cutting device according to any one of the first to fifth techniques is attached.

[0218] In this way, it is possible to obtain a cutting device equipped with an attachment that allows the cutting height to be selectively changed while more reliably preventing variations in cutting height when cutting hair to achieve the selected cutting height.

[0219] [others] The above describes the attachment and cutting device to which the attachment is attached according to the present disclosure, but it will be obvious to those skilled in the art that the present disclosure is not limited to these descriptions and that various modifications and improvements are possible.

[0220] For example, the present disclosure can be applied to embodiments in which the configurations shown in the above-described embodiments and their modifications have been changed, replaced, added, omitted, etc. Furthermore, it is also possible to combine the components described in the above-described embodiments and their modifications to create new embodiments.

[0221] Furthermore, in the above embodiment and its variations, clippers for cutting human hair, animal hair, etc. are exemplified as cutting devices to which attachments are attached, but the present disclosure can also be applied to attachments attached to other cutting devices, such as beard trimmers.

[0222] Furthermore, in the above embodiment and its modified examples, the attachment 3 including the first comb portion 50 and the second comb portion 60 has been exemplified, but it is also possible to provide an attachment including only one comb portion.

[0223] The present disclosure can also be applied to a sliding attachment, and to an attachment that does not have an adjustable cutting height (an attachment that has only one set cutting height).

[0224] It is also possible to configure the substrate (base) 30 without the thin plate (intersecting wall portion) 32.

[0225] Furthermore, in the above embodiment and its modified examples, a type of hair clipper 1 in which the head 20 is detachably attached to the body 10 is exemplified, but it is also possible to make a hair clipper (cutting device) in which the body and head are integrated.

[0226] The hair clipper head can also be used as part of a personal care kit that can be fitted with heads having various functions (such as an electric toothbrush head or an electric razor head) on a common body.
