[0009] 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.
[0010] 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.
[0011] In the following embodiments and their modifications, a hair clipper that cuts the hair (an example of hair) of a user or the like will be exemplified as the cutting device.
[0012] In the following embodiments and their modifications, the direction in which the movable blade slides back and forth relative to the fixed blade or the width direction of the clippers is defined as the Y direction. Furthermore, the vertical direction or up-down direction when the clippers are positioned so that the blade is located at the top and the body is located at the bottom is defined as the Z direction. The front-to-back direction of the clippers, which intersects (is perpendicular to) the Y and Z directions, is defined as the X direction.
[0013] Furthermore, when describing the hair clippers in the following embodiments and their modifications, the side on which the switch is provided is defined as the front.
[0014] (Embodiment) As shown in Figures 1 to 8, the hair clippers 10 of this embodiment include a main body 11 and a blade block 40 that is removably attached to the main body 11, and the main body 11 is formed with a grip portion 11a that can be held by hand.
[0015] The hair clippers 10 are a device for treating and styling the hair H of a subject U, for example, by cutting the hair H of the subject U to a desired length. Specifically, the blade block 40 includes a metal fixed blade 47 and a metal movable blade 46 that slides back and forth in the Y direction relative to the fixed blade 47. The blade block 40 is attached to the main body 11, and a linear motor 72, which serves as a drive unit housed within the main body 11, is used as a drive source to slide the movable blade 46 back and forth in the Y direction relative to the fixed blade 47, thereby sandwiching and cutting the hair H between the fixed blade 47 and the movable blade 46.
[0016] In this embodiment, the main body 11 is provided with a housing 12 formed of a material such as synthetic resin and forming the outer shell of the main body 11, and a switch 12a is attached to the front surface of the housing 12 so that it can be pushed inward while being exposed to the outside. Furthermore, a display 12b is formed on the front surface of the housing 12, which allows the on / off state of the power supply to be visually confirmed.
[0017] In this embodiment, the housing 12 is formed by joining multiple segments together, forming a cavity inside the housing 12. Various electrical components are accommodated in this cavity. The multiple segments can be joined together by, for example, using screws or by fitting the segments together.
[0018] A rechargeable battery 841 serving as a power supply and a linear motor 72 driven by the rechargeable battery 841 are housed in a cavity formed inside the housing 12. A drive shaft 73 that transmits the driving force of the linear motor 72 to the blade block 40 is also housed in a cavity formed inside the housing 12. In this embodiment, as shown in FIG. 8, the drive shaft 73 is housed in the cavity inside the housing 12 with its tip protruding toward the blade block 40 (upper side in FIG. 8), and is connected to a guide plate 42 of the blade block 40, which will be described later. Note that the method for driving the blade block 40 is not limited to the method described above, and various methods are possible.
[0019] Furthermore, a control board 842 that controls the power supply to the linear motor 72 in response to the pressing operation of the switch portion 12a exposed to the outside is housed in a cavity formed inside the housing 12.
[0020] The blade block 40 has a function of cutting hair H, and includes a blade portion 45 as a hair clipper blade formed by arranging a movable blade 46 and a fixed blade 47 so that they face each other, as shown in Figures 8, 15, and 16. The blade portion 45 is configured so that the movable blade crosspiece 461 of the movable blade 46 slides back and forth in the Y direction relative to the fixed blade crosspiece 471 of the fixed blade 47.
[0021] 8 and 16, the blade block 40 further includes a resin fixed plate 41 on which the blade portion 45 is disposed, and a resin guide plate 42 fixed to the movable blade 46. The blade block 40 also includes a metal push-up spring 43 that presses the movable blade 46 toward the fixed blade 47, and a resin switching lever 44 that holds the push-up spring 43. In this embodiment, the switching lever 44 is held by the fixed plate 41 in a state that allows it to rotate relatively to the fixed plate 41, and can be tilted between a lying position and an upright position.
[0022] The fixed plate 41 is a member that is fixed to the main body 11 with the fixed blade 47 fixed thereto, and includes a hook portion 41a for engaging with the main body 11.
[0023] The guide plate 42 is a member that is connected to the drive shaft 73 with the blade block 40 attached to the main body 11 and that reciprocates in the Y direction, and the movable blade 46 is fixed to this guide plate 42. The movable blade 46 slides back and forth in the Y direction relative to the fixed blade 47 in conjunction with the reciprocating movement of the guide plate 42 in the Y direction.
[0024] The push-up spring 43 is a member that presses the movable blade 46 toward the fixed blade 47, thereby ensuring that the movable blade crosspiece 461 and the fixed blade crosspiece 471 slide in contact with each other more reliably, and can be formed of, for example, a torsion spring.
[0025] Furthermore, in this embodiment, as shown in Figures 15 and 16, the blade stop spring 74 is fixed to the housing 12 by a screw or the like, and this blade stop spring 74 holds the blade block 40, thereby preventing the blade block 40 from coming off the housing 12.
[0026] In this embodiment, an attachment (not shown) can be attached to the blade block 40, and by attaching the attachment, the cutting height of the clippers 10 can be changed.
[0027] Furthermore, with the hair clippers 10 according to this embodiment, the cutting height of the hair H can be changed without using an attachment, and the main body 11 is provided with a cutting height adjustment mechanism 20. By operating the cutting height adjustment mechanism 20, the switching lever 44 is raised and lowered, and by raising and lowering the switching lever 44, the cutting height of the hair H can be changed.
[0028] As shown in Figures 8, 15, and 16, the cutting height adjustment mechanism 20 includes a cutting height adjustment dial 21 rotatably attached to the main body 11, and a transmission mechanism 22 that raises or lowers the switching lever 44 of the blade block 40 in conjunction with the rotation of the dial 21. In this embodiment, the cutting height adjustment dial 21 is provided on the front side (front side) of the housing 12, closer to the blade block 40 (upper side) than the switch unit 12a, so as to be rotatable relative to the housing 12. In this case, the dial 21 can be rotated relative to the housing 12 about a rotation shaft 211, as shown in Figure 8.
[0029] As shown in FIGS. 8, 15, and 16, the transmission mechanism 22 is accommodated in a cavity formed inside the housing 12, and includes a first conversion mechanism 221 and a second conversion mechanism 222.
[0030] Here, the first conversion mechanism 221 is a mechanism that converts the rotation of the dial 21 into linear movement in the Z direction, which is the radial direction of the dial 21, when the dial 21 is rotated clockwise or counterclockwise around the rotation shaft 211. As shown in FIGS. 15 and 16 , the first conversion mechanism 221 includes a connecting lever 2211, which is provided with a rod 22111 having a pin 22112 and a slider 22113 provided at the tip of the rod 22111. When the dial 21 is rotated, the pin 22112 moves in a groove formed in the dial 21 in conjunction with the rotation of the dial 21. In this way, the rod 22111 and the slider 22113 move linearly in the Z direction, which is the radial direction of the dial 21, in conjunction with the movement of the pin 22112 in the groove.
[0031] Furthermore, in this embodiment, as shown in FIG. 8, a coil spring 2212 is attached to the rod 22111, and this coil spring 2212 adjusts the load required when rotating the dial 21.
[0032] On the other hand, the second conversion mechanism 222 is a mechanism that converts the linear movement converted by the first conversion mechanism 221 into rotation about a rotation axis extending in the Y direction, and is provided with an operating shaft 2221. As shown in Fig. 8, this operating shaft 2221 is attached to a hook portion 22114 provided on the slider 22113 in a state where it extends in the Y direction, and moves linearly in the Z direction together with the slider 22113.
[0033] 15 and 16, the second conversion mechanism 222 further includes a rotating member 2222 having one end connected to the operating shaft 2221. In this embodiment, the pair of rotating members 2222 are connected to both ends of the operating shaft 2221 in the Y direction (width direction).
[0034] When the operating shaft 2221 is moved linearly in the Z direction, the rotating member 2222 rotates in conjunction with the linear movement of the operating shaft 2221, and the switching lever 44 is raised or lowered in conjunction with the rotation of the rotating member 2222.
[0035] In this embodiment, when the dial 21 is rotated counterclockwise, the slider 22113 and the operating shaft 2221 move linearly downward. The rotating member 2222 rotates in conjunction with the downward movement of the operating shaft 2221. At this time, the rotating member 2222 rotates such that one end connected to the operating shaft 2221 moves downward and the other end moves upward. This causes the switching lever 44 to rotate toward the upright position against the biasing force of the push-up spring 43, and the movable blade 46 slides toward the tip (upward) via the push-up spring 43 and the guide plate 42 while maintaining a pressing state against the fixed blade 47.
[0036] On the other hand, when the dial 21 is rotated clockwise, the slider 22113 and the operating shaft 2221 move linearly upward. The rotating member 2222 rotates in accordance with the upward movement of the operating shaft 2221. At this time, the rotating member 2222 rotates so that one end connected to the operating shaft 2221 moves upward and the other end moves downward. This rotates the switching lever 44 to the lying-down position, and via the push-up spring 43 and the guide plate 42, the movable blade 46 slides toward the base (downward) while maintaining a pressing state against the fixed blade 47.
[0037] At this time, the movable blade 46 slides on the tapered portion of the fixed blade 47. That is, in this embodiment, the movable blade 46 slides between the root side and the tip side on the tapered portion of the fixed blade 47. In this way, the hair cutting height can be changed.
[0038] In this embodiment, the cutting height adjustment mechanism 20 is equipped with a holding mechanism 23 that can hold the dial 21 in stages, and by holding the dial 21 in stages with this holding mechanism 23, the cutting height can be changed in stages.
[0039] Specifically, the holding mechanism 23 includes a holding spring 231 fixed to a fixing portion 7111 provided on the main body 11. The dial 21 is rotated to releasably engage the holding spring 231 with one of a plurality of engaged portions formed on the back side of the dial 21, thereby holding the dial 21 in stages.
[0040] In this manner, in this embodiment, by operating the dial 21 of the cutting height adjustment mechanism 20, the cutting height can be set to a plurality of levels.
[0041] Here, in this embodiment, the operability of the hair clippers 10 can be further improved.
[0042] Specifically, as shown in Figures 1 to 8, the main body portion 11 is elongated in the Z direction and comprises a first main body portion 70 to which the blade portion 45 is attached on the upper side in the Z direction, and a second main body portion 80 connected to the lower side of the first main body portion 70.
[0043] The second main body portion 80 is connected to the lower side of the first main body portion 70 in a state that is elongated in the Y direction, which is a direction intersecting the Z direction.
[0044] As described above, in this embodiment, the main body 11 includes a first main body 70 arranged with its longitudinal direction substantially aligned with the Z direction as a first direction, and a second main body 80 arranged with its longitudinal direction substantially aligned with the Y direction as a second direction. The first main body 70 has the blade 45 attached to its upper end (one end in the first direction) and the second main body 80 is connected to its lower end (the other end in the first direction) so as to be elongated in the Y direction.
[0045] By doing so, the longitudinal direction of the first body portion 70 and the longitudinal direction of the second body portion 80 intersect, thereby shortening the overall length of the body portion 11. Here, the overall length of the body portion 11 refers to the vertical length from the end of the body portion 11 on the blade portion 45 side to the end on the opposite side of the blade portion 45. In this embodiment, the overall length of the body portion 11 is set to approximately 160 mm, so that most of the hair clippers 10 can fit within the hand H1. This more reliably prevents the hair clippers 10 from being dropped when in use.
[0046] Furthermore, by shortening the overall length of the main body 11, as shown in FIG. 29 , when using the hair clippers 10 to cut the hair H of the subject U, the lower end of the main body 11 can be more reliably prevented from hitting the shoulders of the subject U, thereby improving the operability of the hair clippers 10. Note that a conventional hair clipper is shown in FIG. 29 by a two-dot chain line. From the description in FIG. 29 , it can be seen that even when a conventional hair clipper is used in a way that would cause the hair clipper to hit the shoulders of the subject U, the hair clipper 10 described in this embodiment can cut the hair H without hitting the shoulders of the subject U. In other words, it can be seen that the hair clipper 10 described in this embodiment can provide improved operability compared to conventional hair clippers.
[0047] Furthermore, as in this embodiment, by configuring the main body 11 with only two parts, the first main body 70 and the second main body 80, the shape of the main body 11 is prevented from becoming complex, and it can be made into a shape that is easier to grip.
[0048] In this case, the lower end (the other end in the first direction) of the first main body portion 70 may be connected to the center in the Y direction of the second main body portion 80. In other words, the second main body portion 80 may be connected to the first main body portion 70 in a state where it protrudes on both sides in the Y direction beyond the first main body portion 70.
[0049] This makes it easier to grip the second main body portion 80 with the hand H1, further improving the operability of the hair clippers 10.
[0050] Furthermore, the longitudinal direction of the second main body part 80 may be made to substantially coincide with the Y direction, which is the direction of reciprocation of the movable blade 46 relative to the fixed blade 47. In other words, the longitudinal direction of the second main body part 80 and the direction of reciprocation of the movable blade 46 relative to the fixed blade 47 may be made to be substantially parallel. This makes it easier to place the blade part 45 against the scalp of the subject U while holding the second main body part 80 with the hand H1. Also, the direction of reciprocation of the movable blade 46 relative to the fixed blade 47 can be more easily recognized.
[0051] In this embodiment, as shown in FIG. 16 , the first main body 70 includes a first housing 71 formed of a material such as synthetic resin and constituting an outer shell of the first main body 70. The first housing 71 is formed by joining together a plurality of divided bodies. Specifically, the first housing 71 includes a first front housing 711 and a first rear housing 712. Joining the first front housing 711 and the first rear housing 712 forms a portion of the first housing 71 having an internal cavity. In this embodiment, the linear motor 72 and the drive shaft 73 are housed in the cavity formed in the first housing 71. Specifically, a partition wall 7121 is formed on the upper portion of the first rear housing 712, and a through-hole 71211 penetrating in the Z direction is formed in the center of the partition wall 7121. The linear motor 72 is placed below the partition wall 7121 in the first rear housing 712 with its drive shaft 73 inserted from below into the through-hole 71211. In this embodiment, the through-hole 71211 is closed by a dustproof cover 75 to prevent water, dust, and the like from entering the linear motor 72 when the first main body portion 70 is formed.
[0052] Furthermore, in this embodiment, the blade block 40 and the cutting height adjustment mechanism 20 are attached to the first main body 70. Therefore, in this embodiment, the first housing 71 includes a blade base 713 that holds the blade block 40 and a cover 714 that covers a portion of the dial 21 while allowing the dial 21 to rotate. The cover 714 also includes a cover main body 7141 and a finger rest 7142 that is attached to the cover main body 7141 and allows fingers such as the thumb F1 to be placed on the cover main body 7141 when the hair clippers 10 are held. When the cover main body 7141 is attached to the first front housing 711, the front side of the blade block 40 is covered by the cover main body 7141. This configuration forms the first main body 70, which houses the linear motor 72 and the drive shaft 73, and exposes the blade portion 45 from the upper end and the dial 21 forward.
[0053] On the other hand, as shown in Fig. 17, the second main body 80 includes a second housing 81 that is made of a material such as synthetic resin and forms the outer shell of the second main body 80. This second housing 81 is also formed by joining together a plurality of divided bodies. Specifically, the second housing 81 includes a second front housing 811 and a second rear housing 812. The second front housing 811 and the second rear housing 812 are joined together to form the second housing 81 that has a cavity formed inside.
[0054] In this embodiment, a rechargeable battery 841 is accommodated in a cavity formed in the second housing 81. Specifically, the rechargeable battery 841 is held in a battery holder 8421 attached to a control board 842 to form a circuit block 84, which is accommodated in the cavity formed in the second housing 81, so that the rechargeable battery 841 is accommodated in the second main body 80.
[0055] In the present embodiment, a through-hole 8111 is formed in the second front housing 811, and the switch button 82 is inserted into and held in this through-hole 8111 in a state where it can be protruded and retracted in the X direction. Specifically, a cover member 83 is disposed inside the second front housing 811, and a switch button holding portion 832 that holds the switch button 82 is formed in this cover member 83. Then, with the switch button 82 held in the switch button holding portion 832, the front portion of the switch button 82 is inserted into the through-hole 8111 from the inside (rear side), so that the switch button 82 is held in the second front housing 811 in a state where it can be protruded and retracted in the X direction. In this manner, the switch unit 12a is formed on the front surface 801 of the second main body portion 80.
[0056] Furthermore, in this embodiment, a through hole 8112 is formed in the second front housing 811, and a lamp cover portion 831 formed on the cover member 83 is inserted into the through hole 8112 when the cover member 83 is disposed inside the second front housing 811. In this manner, the display unit 12b is formed on the front surface 801 of the second main body portion 80. The lamp cover portion 831 covers a light source such as an LED mounted on the control board 842, and has the function of guiding light emitted from the light source.
[0057] In this manner, in this embodiment, the first main body portion 70 accommodates a linear motor 72 capable of driving the blade portion 45, while the second main body portion 80 accommodates a rechargeable battery 841 capable of supplying power to the linear motor 72.
[0058] This makes it possible to more evenly balance the weight of the first main body 70 and the second main body 80, and to position the center of gravity G of the main body 11 more centrally. This improves operability when holding the hair clippers 10 in various ways, and makes the hair clippers 10 easier to use.
[0059] It is not necessary to accommodate the linear motor 72 in the first main body portion 70 while accommodating the rechargeable battery 841 in the second main body portion 80; the linear motor 72 and the rechargeable battery 841 can be accommodated in various locations in the main body portion 11.
[0060] Furthermore, when the main body 11 is viewed along the X direction as the third direction, the lower surface 805 of the second main body 80 may be configured to have a curved surface 8051 that is curved so as to be convex downward. In other words, when the second main body 80 is connected to the first main body 70 so as to be elongated in the Y direction and viewed along the X direction, the lower surface 805 in the Z direction (the surface on the other end side in the first direction) may be configured to have a curved shape that is convex (convex downward) in a direction away from the first main body 70.
[0061] In this way, when the side of the main body 11 opposite to the blade portion 45 (the lower end of the main body 11) is gripped with the hand H1, a larger portion of the lower surface 805 (the surface on the other end side in the first direction) of the second main body 80 can come into contact with the palm H11. As a result, the second main body 80 can be firmly gripped with the hand H1, which further reduces the strain on the wrist during comb cutting, which will be described later.
[0062] When viewing the main body 11 along the X direction, the top surface 804 of the second main body 80 may be curved to be convex downward. This allows the shape of the second main body 80 to resemble the grip of a steering wheel of a car or the like, allowing the second main body 80 to be more firmly gripped with the hand H1. Furthermore, if the shape of the second main body 80 resembles the grip of a steering wheel, the fingers gripping the second main body 80 are less likely to slip out, further improving the operability of the hair clippers 10.
[0063] Furthermore, the second main body 80 may be provided with a self-standing means that allows the main body 11 (hair clippers 10) to stand on its own with the blade 45 facing upward. This allows the hair clippers 10 to be placed with the blade 45 facing upward without using an auxiliary member such as a charging stand.
[0064] In this embodiment, ribs 806 as self-supporting means extending in the X and Z directions are formed on both sides in the Y direction of the underside 805 of the second main body 80. If such ribs 806 are provided on the underside 805 of the second main body 80 and the lower ends of the ribs 806 are brought into contact with the mounting surface 121 of the mounting portion 120 such as a desk, the hair clippers 10 can stand on the mounting surface 121 with the blade 45 positioned at the top.
[0065] In this way, by allowing the hair clippers 10 to stand on their own, damage to the blade portion 45 can be more reliably prevented, and the appearance of the hair clippers 10 in the placed state can be further improved. Furthermore, damage to the blade portion 45 can be prevented without using auxiliary components such as a charging stand or a component for protecting the blade portion 45, which can reduce manufacturing costs. Furthermore, the operation of placing the hair clippers 10 on the placement surface 121 when not in use and the operation of gripping the hair clippers 10 placed on the placement surface 121 when using the hair clippers 10 are simplified, which further improves the ease of use of the hair clippers 10.
[0066] Furthermore, a connector 8031 to which an AC cord 100 serving as an external connection cord is connected may be formed on a side surface 803 of the second main body 80. That is, in a state in which the second main body 80 is connected to the first main body 70 so as to be elongated in the Y direction, the connector 8031 to which the AC cord 100 is connected may be formed on the side surface 803, which is a portion that becomes the end face of the second main body 80 in the Y direction.
[0067] This allows the cutter to be used while receiving external power via the external connection cord. Also, by connecting the external connection cord to the end face of the second body in the second direction, it is possible to minimize the external connection cord getting in the way when using the cutter while receiving external power via the external connection cord.
[0068] Furthermore, the second main body 80 may be formed with a USB connector 8021 to which the USB cord 110 is connected. In this way, the rechargeable battery 841 can also be charged using the USB cord 110.
[0069] In this embodiment, a USB connector 8021 is formed on the rear surface 802 of the second main body 80, and the USB cord 110 can be inserted into the USB connector 8021 while the hair clippers 10 are placed on the placement surface 121. This allows the rechargeable battery 841 to be charged while the hair clippers 10 are placed on the placement surface 121.
[0070] Furthermore, the second main body portion 80 may be connected to the first main body portion 70 via a connecting portion 90. The connecting portion 90 may include a rotation shaft 92. In this way, the second main body portion 80 can be rotated relative to the first main body portion 70.
[0071] In this way, by making it possible to rotate the second main body portion 80 relative to the first main body portion 70, it is possible to more reliably prevent the second main body portion 80 from getting in the way when gripping the first main body portion 70 with the hand H1, making it possible to create a hair clipper 10 that can be gripped in a variety of ways.
[0072] In this embodiment, the connecting portion 90 is provided with a fixing member 91 that is fixed to the first main body portion 70, and this fixing member 91 is configured to be fixed to the first main body portion 70 while holding the linear motor 72.
[0073] The fixing member 91 is formed in a cylindrical shape that opens downward, and has a pair of through holes 911 formed in portions that define the Y direction so as to penetrate in the Y direction. The shaft portion of the rotating shaft 92 is adapted to be inserted into the pair of through holes 911. The connecting part 90 is provided with a shaft cap 93 that is attached to the tip of the shaft portion of the rotating shaft 92, and by attaching the shaft cap 93 to the tip of the shaft portion of the rotating shaft 92 with the rotating shaft 92 inserted into the through hole 911, the rotating shaft 92 is attached to the fixing member 91.
[0074] Furthermore, in the fixed member 91, ball holding portions 912 for holding balls 951 are formed on both sides in the Z direction of each through hole 911, and the balls 951 are held in a state in which they protrude outward in the Y direction by each ball holding portion 912. Therefore, in this embodiment, two balls 951 are held on one side in the Y direction, and two balls 951 are held on the other side in the Y direction.
[0075] The connecting unit 90 also includes a rotating member 94 that is rotatably attached to the shaft portion of the rotating shaft 92 while being fixed to the second main body unit 80. In the present embodiment, the rotating member 94 includes an accommodation wall 941 that is accommodated and held in a holding wall 8121 formed in the second rear housing 812, and a rotating unit 942 that is rotatably attached to the shaft portion of the rotating shaft 92. The rotating unit 942 also has a through hole 9421 that penetrates in the Y direction. The rotating unit 942 is inserted into the fixed member 91 from below, and the pair of through holes 911 and 9421 are communicated with each other, and the shaft portion of the rotating shaft 92 is inserted into the pair of through holes 911 and 9421, thereby rotatably attaching the rotating member 94 to the fixed member 91.
[0076] This allows the second main body portion 80 to rotate relatively back and forth with respect to the first main body portion 70.
[0077] Furthermore, when the second body portion 80 is rotated back and forth relative to the first body portion 70 and reaches a predetermined angular position, the rotation of the second body portion 80 relative to the first body portion 70 may be restricted. Furthermore, when the second body portion 80 reaches an angular position different from the predetermined angular position, the rotation of the second body portion 80 relative to the first body portion 70 may also be restricted.
[0078] In this way, the connecting portion 90 may be provided with a holding mechanism 95 that can hold the second body portion 80 in a stepwise manner as it is rotated back and forth relative to the first body portion 70. This allows the hair clippers 10 to be adapted to various gripping methods. Furthermore, by holding the second body portion 80 in a predetermined state, the second body portion 80 is prevented from moving relative to the first body portion 70 when the hair clippers 10 are in use, thereby further improving the ease of use of the hair clippers 10.
[0079] In this embodiment, a holding mechanism 95 is configured by a ball 951 fixed to a fixed member 91 and a ball receiver 952 fixed to a rotating member 94 .
[0080] Furthermore, a plurality of ball receiving holes 9521 are formed in the ball receiver 952 along the circumferential direction. Each ball 951 fits into one of the plurality of ball receiving holes 9521, thereby restricting rotation of the second main body portion 80 relative to the first main body portion 70.
[0081] In this embodiment, the ball receiver 952 is fixed to the rotating member 94 in a rotation-preventing state by inserting the retaining piece 9522 into an insertion hole 9422 formed in the rotating portion 942. Therefore, when the rotating member 94 is rotated relative to the fixed member 91 and the rotating shaft 92, the ball receiver 952 also rotates in conjunction with the rotation of the rotating member 94. When the ball receiver 952 rotates, the engagement between each ball 951 and a specific ball receiving hole 9521 is released. When the ball receiver 952 rotates in a state in which the engagement between each ball 951 and a specific ball receiving hole 9521 is released, each ball 951 fits into another ball receiving hole 9521 that is circumferentially adjacent to the specific ball receiving hole 9521. In this way, rotation of the second main body portion 80 relative to the first main body portion 70 is restricted when the second main body portion 80 is in an angular position different from the predetermined angular position.
[0082] The connecting portion 90 having such a configuration can be assembled, for example, in the following manner.
[0083] First, the ball 951 is held by the ball holding portion 912 formed on the fixing member 91 .
[0084] Next, the rotating portion 942 of the rotating member 94 is inserted into the fixed member 91 from below so that the pair of through holes 911 and 9421 communicate with each other.
[0085] Next, the holding piece 9522 of the ball receiver 952 is inserted into the insertion hole 9422 formed in the rotating part 942 from the outside in the Y direction (width direction: second direction), and the ball receiver 952 is held on the rotating part 942 with the ball 951 and the fixing member 91 sandwiched therebetween. At this time, the through hole of the ball receiver 952 is in communication with the pair of through holes 911 and 9421.
[0086] Next, the shaft portion of the rotation shaft 92 is inserted through the through-hole of the ball receiver 952 , the pair of through-holes 911 and 9421 .
[0087] Finally, a shaft cap 93 is attached to the tip of the shaft portion of the rotating shaft 92.
[0088] In this way, the connecting portion 90 is assembled.
[0089] By attaching the second main body portion 80 and the first main body portion 70 to this connecting portion 90, the hair clippers 10 can be configured to rotate the second main body portion 80 relative to the first main body portion 70 while gradually changing and holding the rotation angle of the second main body portion 80 relative to the first main body portion 70.
[0090] 9 and 10, the second body block 60, which is made up of the second body portion 80, the rotating member 94, and the ball receiver 952, rotates back and forth relative to the first body block 50, which is made up of the first body portion 70, the fixing member 91, the rotating shaft 92, the shaft cap 93, and the ball 951. Note that although FIGS. 9 and 10 show the first body block 50 with the first front housing 711 and the first rear housing 712 removed, in reality the first body block 50 also includes the first front housing 711 and the first rear housing 712.
[0091] The hair clippers 10 described in this embodiment are designed to prevent deterioration in operability even when used in various ways of holding the hair clippers.
[0092] Next, a method for holding the hair clippers 10 according to this embodiment will be described. Note that the holding method described below is merely an example, and the hair clippers 10 can also be held in a manner other than the method described below.
[0093] The hair clippers 10 can be held, for example, in the manner shown in Figures 19 and 20. Figures 19 and 20 show a way of holding the hair clippers 10 with the thumb F1 placed on the finger rest 7142 and the other fingers (index finger F2, middle finger F3, ring finger F4, little finger F5) placed on the back surface of the main body 11. That is, in the way shown in Figures 19 and 20, the hair clippers 10 are held with the hand H1 wrapped around the right side of the first main body 70.
[0094] Even when the hair clippers 10 are held in this manner, the hair clippers 10 can be used with good operability.
[0095] For example, by holding the hair clippers 10 in this manner, the user can move the hair clippers 10 from bottom to top to cut (shave) the hair H of the subject U. In this case, since the overall length of the main body 11 of the hair clippers 10 according to the present embodiment is short, it is possible to more reliably prevent the bottom end of the main body 11 from hitting the shoulders of the subject U, thereby further improving the operability of the hair clippers 10.
[0096] It is also possible to hold the hair clippers 10 in the manner shown in Fig. 21. Fig. 21 shows a way of holding the hair clippers 10 with the thumb F1 placed on the left side of the first main body portion 70 and the other fingers (index finger F2, middle finger F3, ring finger F4, little finger F5) placed on the back surface of the main body portion 11. That is, in the way shown in Fig. 21, the hair clippers 10 are held with the hand H1 wrapped around the front surface of the first main body portion 70.
[0097] Even when the hair clippers 10 are held in this manner, the hair clippers 10 can be used with good operability.
[0098] For example, by holding the hair clippers 10 in this manner, the user can move the hair clippers 10 from bottom to top to cut (shave) the hair H of the subject U. In this case, since the overall length of the main body 11 of the hair clippers 10 according to the present embodiment is short, it is possible to more reliably prevent the bottom end of the main body 11 from hitting the shoulders of the subject U, thereby further improving the operability of the hair clippers 10.
[0099] The hair clippers 10 can also be held in the manner shown in Fig. 22. Fig. 22 shows a way of holding the hair clippers 10 with the thumb F1 placed on the right side of the first main body portion 70 and the other fingers (index finger F2, middle finger F3, ring finger F4, little finger F5) placed on the front of the main body portion 11. That is, in the way shown in Fig. 22, the hair clippers 10 are held in a state where the hand H1 is wrapped around the rear surface of the first main body portion 70 (backhand grip).
[0100] Even when the hair clippers 10 are held in this manner, the hair clippers 10 can be used with good operability.
[0101] For example, if the hair clippers 10 are held in this manner, the hair clippers 10 can be moved from above to below to cut the hair H of the subject U (to finely adjust the length of the hair).
[0102] The hair clippers 10 can also be held as shown in FIGS. 23 and 24. FIGS. 23 and 24 show a holding method in which the side of the first body portion 70 is pinched between the thumb F1 and the index finger F2 and middle finger F3, while the ring finger F4 and little finger F5 are placed on the rear surface of the body portion 11. In other words, in the holding method shown in FIGS. 23 and 24, the hair clippers 10 are held in a manner similar to gripping a pen. At this time, the second body portion 80 is rotated forward relative to the first body portion 70. This prevents the second body portion 80 from getting in the way of the hand H1 when gripping the first body portion 70.
[0103] Even when the hair clippers 10 are held in this manner, the hair clippers 10 can be used with good operability.
[0104] For example, if the hair clippers 10 are held in this manner, the hair H on the top of the head of the subject U can be cut by moving the hair clippers 10 from rear to front.
[0105] The hair clippers 10 can also be held as shown in FIGS. 25 and 26. FIGS. 25 and 26 show a holding method for holding the hair clippers 10 with the thumb F1 placed on the left side of the first body portion 70, the index finger F2 and middle finger F3 placed on the right side of the first body portion 70, and the ring finger F4 and little finger F5 placed on the top surface 804 of the second body portion 80. That is, in the holding method shown in FIGS. 25 and 26, the hair clippers 10 are held with the hand H1 wrapped around the front of the first body portion 70 and the fingers pinching the sides of the first body portion 70. At this time, the second body portion 80 is rotated backward relative to the first body portion 70. This prevents the second body portion 80 from getting in the way of the hand H1 when pinching the first body portion 70.
[0106] Even when the hair clippers 10 are held in this manner, the hair clippers 10 can be used with good operability.
[0107] For example, by holding the hair clippers 10 in this manner, the user can move the hair clippers 10 from bottom to top to cut (shave) the hair H of the subject U. In this case, since the overall length of the main body 11 of the hair clippers 10 according to the present embodiment is short, it is possible to more reliably prevent the bottom end of the main body 11 from hitting the shoulders of the subject U, thereby further improving the operability of the hair clippers 10.
[0108] 27 and 28 show a holding method for holding the hair clippers 10 in such a manner that the underside 805 of the second body portion 80 is in contact with the palm H11, the thumb F1 is placed on the front side of the second body portion 80, and the other fingers (index finger F2, middle finger F3, ring finger F4, little finger F5) are placed on the rear side of the second body portion 80 and the rear side of the first body portion 70. That is, in the holding method shown in FIGS. 27 and 28, the hair clippers 10 are held with the tip (underside 805) of the second body portion 80 facing the palm H11 and wrapped around the hand H1, with the front and rear sides of the second body portion 80 sandwiched between the fingers.
[0109] Even when the hair clippers 10 are held in this manner, the hair clippers 10 can be used with good operability.
[0110] For example, by holding the hair clippers 10 in this manner, it becomes possible to use the comb 130 to cut (comb cut) the hair (head hair) H of the subject U. In this case, since the overall length of the main body 11 of the hair clippers 10 according to the present embodiment is short, the center of gravity G of the hair clippers 10 can be positioned closer to the palm H11 than the fingertips. In this way, the hair clippers 10 can be held stably in the manner shown in FIGS. 27 and 28. As a result, it becomes possible to more reliably prevent the hair clippers 10 from shaking when in use.
[0111] Furthermore, if the hair clippers 10 are held in the manner shown in Figures 27 and 28, the main body 11 can be held without bending the wrist, thereby further reducing the strain on the wrist when combing.
[0112] The hair clippers 10 may also have the configurations shown in FIGS.
[0113] The hair clippers 10 shown in Figures 30 to 35 are also elongated in the Z direction and include a first main body portion 70 to which the blade portion 45 is attached on the upper side in the Z direction, and a second main body portion 80 connected to the lower side of the first main body portion 70.
[0114] The second main body portion 80 can be provided below the first main body portion 70 and connected thereto in an elongated state in a direction intersecting the Z direction.
[0115] As such, in Figures 30 to 35, the main body portion 11 is configured to include a first main body portion 70 that is arranged with its longitudinal direction approximately aligned with the Z direction as a first direction, and a second main body portion 80 that can be arranged with its longitudinal direction approximately aligned with the X direction as a second direction that intersects with the Z direction.
[0116] 30 to 35, the second main body portion 80 can be connected to the first main body portion 70 via a connecting portion 90. That is, the second main body portion 80 can be made to rotate relatively with respect to the first main body portion 70.
[0117] 30 to 35 show an example in which one longitudinal end of the second main body portion 80 is connected to the underside of the first main body portion 70 via a connecting portion 90. The example also shows an example in which the second main body portion 80 can be rotated back and forth relative to the first main body portion 70 with the Y direction as an axis.
[0118] Therefore, Figures 30 to 35 show examples of hair clippers 10 in which second body portion 80 is connected to first body portion 70 so that it can protrude to only one side in the second direction relative to the first body portion 70.
[0119] This also makes it possible to further improve the operability of the hair clipper 10.
[0120] In this way, the hair clippers 10 shown in FIGS. 30 to 35 can also achieve substantially the same effects and advantages as the hair clippers 10 shown in the above embodiment.
[0121] In addition, the hair clippers 10 shown in Figures 30 to 35 can also be configured so that the longitudinal direction of the second main body portion 80 is approximately aligned with the longitudinal direction of the first main body portion 70, making it possible to select a configuration that is approximately the same as that of conventional hair clippers.
[0122] The hair clippers 10 may also have the configurations shown in FIGS.
[0123] The hair clippers 10 shown in Figures 36 to 41 are also elongated in the Z direction and include a first main body portion 70 to which the blade portion 45 is attached on the upper side in the Z direction, and a second main body portion 80 connected to the lower side of the first main body portion 70.
[0124] The second main body portion 80 can be provided below the first main body portion 70 and connected thereto in an elongated state in a direction intersecting the Z direction.
[0125] As such, in Figures 36 to 41, the main body portion 11 is configured to include a first main body portion 70 that is arranged with its longitudinal direction approximately aligned with the Z direction as a first direction, and a second main body portion 80 that can be arranged with its longitudinal direction approximately aligned with the Y direction as a second direction that intersects with the Z direction.
[0126] 36 to 41, the second main body portion 80 can be connected to the first main body portion 70 via a connecting portion 90. That is, the second main body portion 80 can be made to rotate relatively with respect to the first main body portion 70.
[0127] 36 to 41 show an example in which one longitudinal end of the second main body portion 80 is connected to the underside of the first main body portion 70 via a connecting portion 90. The example also shows an example in which the second main body portion 80 can be rotated left and right relative to the first main body portion 70 with the X direction as an axis.
[0128] Therefore, Figures 36 to 41 show examples of hair clippers 10 in which second body portion 80 is connected to first body portion 70 so that it can be protruded to only one side in the second direction relative to the first body portion 70.
[0129] This also makes it possible to further improve the operability of the hair clipper 10.
[0130] In this way, the hair clippers 10 shown in FIGS. 36 to 41 can also achieve substantially the same effects and advantages as the hair clippers 10 shown in the above embodiment.
[0131] In addition, the hair clippers 10 shown in Figures 36 to 41 can also be configured so that the longitudinal direction of the second main body portion 80 is approximately aligned with the longitudinal direction of the first main body portion 70, making it possible to select a configuration that is approximately the same as that of conventional hair clippers.
[0132] The hair clippers 10 may also be configured as shown in FIGS.
[0133] The hair clippers 10 shown in Figures 42 and 43 are also elongated in the Z direction and comprise a first main body portion 70 to which the blade portion 45 is attached on the upper side in the Z direction, and a second main body portion 80 connected to the lower side of the first main body portion 70.
[0134] The second main body portion 80 is connected to the lower side of the first main body portion 70 in a state that is elongated in the X direction, which is a direction intersecting the Z direction.
[0135] Thus, in Figures 42 and 43, there is provided a first main body portion 70 arranged with its longitudinal direction approximately aligned with the Z direction as a first direction, and a second main body portion 80 arranged with its longitudinal direction approximately aligned with the X direction as a second direction that intersects with the Z direction.
[0136] In this way, the hair clippers 10 shown in FIGS. 42 and 43 can also achieve substantially the same effects and advantages as the hair clippers 10 shown in the above embodiment.
[0137] In the hair clippers 10 shown in FIGS. 42 and 43, the second main body portion 80 may also be configured to be rotatable relative to the first main body portion 70.
[0138] (Addendum) The above description of the embodiments discloses the following techniques.
[0139] (Technology 1) A cutting device comprising: a main body; and a blade portion attached to one end of the main body in a first direction, the main body being elongated in the first direction; a first main body having the blade portion attached to one end in the first direction; and a second main body that can be connected to the other end of the first main body in the first direction in an elongated state in a second direction that intersects with the first direction.
[0140] This makes it possible to make the longitudinal direction of the first main body portion intersect with the longitudinal direction of the second main body portion, thereby shortening the overall length of the main body portion, i.e., the length in the first direction from the end of the main body portion on the blade side to the end opposite the blade portion.
[0141] In this way, by shortening the overall length of the main body, it becomes possible to prevent the tip of the main body (the other end in the first direction) from hitting the subject's shoulder when the blade of the cutting device is placed against the subject's hair from below (neck side) and moved upward to cut the hair.
[0142] Furthermore, by shortening the overall length of the main body, when the tip end (the other end in the first direction) of the second main body is held facing the palm and the side of the first main body is grasped with the fingers, the center of gravity of the cutting device can be positioned closer to the palm than the fingertips. In other words, the cutting device can be held with the center of gravity located in the hand. This allows the cutting device to be stably held with the hand wrapped around the side of the main body opposite the blade. As a result, shaking of the cutting device can be more reliably prevented when the cutting device is held with the hand wrapped around the side of the main body opposite the blade.
[0143] By shortening the overall length of the main body in this way, it is possible to make the cutting device easy to use even when the side of the main body opposite the blade portion is held by wrapping the hand around it. Furthermore, by holding the side of the main body opposite the blade portion by wrapping the hand around it, it becomes possible to hold the main body without bending the wrist. Therefore, by holding the side of the main body opposite the blade portion by wrapping the hand around it, it becomes possible to use a comb to cut the subject's hair (comb cut) while holding the main body without bending the wrist, which further reduces the strain on the wrist when comb cutting.
[0144] Furthermore, by shortening the overall length of the main body, the main body can be more easily held in the palm of the hand when holding the cutting device, which makes it possible to more reliably prevent the cutting device from being dropped when in use.
[0145] As described above, if the cutting device is configured as described in Technique 1, the operability of the cutting device can be further improved.
[0146] Furthermore, if the main body portion is made up of only two parts, the first main body portion and the second main body portion, the shape of the main body portion is prevented from becoming complex, and it can be made into a shape that is easier to grip.
[0147] (Technology 2) The cutting device described in Technology 1, wherein the main body portion is configured so that the second main body portion can be connected to the first main body portion in a state where the second main body portion protrudes on both sides in the second direction more than the first main body portion.
[0148] This makes it easier to grip the second main body portion with the hand, further improving the operability of the cutting device.
[0149] (Technology 3) The cutting device according to Technology 1 or Technology 2, wherein the first body portion houses a drive unit capable of driving the blade portion, and the second body portion houses a power supply unit capable of supplying power to the drive unit.
[0150] This allows for a more even weight balance between the first and second main bodies, and allows the center of gravity of the main bodies to be positioned more centrally. Positioning the center of gravity of the main body more centrally also improves operability when the cutting device is held in various ways, thereby further improving the ease of use of the cutting device.
[0151] (Technology 4) A cutting device according to any one of technologies 1 to 3, wherein the blade portion comprises a fixed blade and a movable blade that reciprocates relative to the fixed blade, and the reciprocating direction of the movable blade relative to the fixed blade is the second direction.
[0152] In this way, the longitudinal direction of the second main body part and the reciprocating direction of the movable blade are approximately parallel, making it easier to place the blade part against the scalp, etc., while holding the second main body part in one's hand. Also, by making the longitudinal direction of the second main body part and the reciprocating direction of the movable blade approximately parallel, it becomes easier to recognize the reciprocating direction of the movable blade.
[0153] (Technology 5) A cutting device according to any one of technologies 1 to 4, wherein when the second main body portion is connected to the first main body portion so as to be elongated in the second direction and viewed along a third direction intersecting the first and second directions, the surface on the other end side in the first direction has a curved shape that is convex in a direction away from the first main body portion.
[0154] In this way, when the user wraps his / her hand around the side of the main body opposite the blade, a larger portion of the other end of the second main body in the first direction comes into contact with the palm of the hand, allowing the user to grip the second main body firmly in his / her hand, further reducing the strain on the wrist when combing.
[0155] (Technology 6) A cutting device according to any one of technologies 1 to 5, wherein the second main body portion is connected to the first main body portion via a connecting portion, and the connecting portion has a rotation axis that allows the second main body portion to rotate relative to the first main body portion.
[0156] By allowing the second body to rotate relative to the first body, it is possible to more reliably prevent the second body from interfering with gripping the first body, resulting in a cutting device that can be adapted to various gripping styles.
[0157] (Technology 7) The cutting device according to Technology 6, wherein the connecting portion is provided with a holding mechanism capable of holding the second main body portion in stages.
[0158] This also makes it possible to provide a cutting device that can be held in a variety of gripping positions. Furthermore, by making it possible to hold the second body in a predetermined position, the second body is prevented from moving relative to the first body when the cutting device is in use, further improving the ease of use of the cutting device.
[0159] (Technology 8) A cutting device according to any one of technologies 1 to 7, wherein the second main body portion is formed with a self-supporting means that enables the main body portion to stand on its own with one end side in the first direction facing upward.
[0160] This allows the cutting device to stand on its own (i.e., placed with the blade portion at the top without using an auxiliary member such as a charging stand). Making the cutting device stand on its own in this way more reliably prevents damage to the blade portion and improves the appearance of the cutting device when placed. Furthermore, since damage to the blade portion can be prevented without using an auxiliary member such as a charging stand or a member for protecting the blade portion, manufacturing costs can be reduced. Furthermore, the operation of placing the cutting device on a placement surface when not in use and the operation of gripping the cutting device placed on a placement surface when in use are simplified, thereby further improving the ease of use of the cutting device.
[0161] (Technology 9) A cutting device according to any one of technologies 1 to 8, wherein, when the second main body portion is connected to the first main body portion so as to be elongated in the second direction, a connector to which an external connection cord is connected is formed on a portion of the second main body portion that serves as an end face in the second direction.
[0162] This allows the cutter to be used while receiving external power via the external connection cord. Also, by connecting the external connection cord to the end face of the second body in the second direction, it is possible to minimize the external connection cord getting in the way when using the cutter while receiving external power via the external connection cord.
[0163] (Technology 10) The cutting device according to any one of Technologies 1 to 9, wherein the second body portion is formed with a USB connector to which a USB cord is connected.
[0164] This will allow you to charge it using a USB cord.
[0165] [others] The cutting device according to the present disclosure has been described above, but it is not limited to this description, and it will be obvious to those skilled in the art that various modifications and improvements are possible.
[0166] For example, the present disclosure can be applied to embodiments in which the configurations shown in the above-described embodiments and their modifications are modified, 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.
[0167] Furthermore, the above embodiment and its modified examples illustrate hair clippers 10 in which second body 80 can be rotated relative to first body 70. However, it is not necessary to rotate second body 80 relative to first body 70, and it is also possible to use hair clippers in which second body 80 is connected to first body 70 in a state where relative movement therebetween is restricted.
[0168] Furthermore, in the above embodiment and its variations, an example is given of a hair clipper 10 in which the second body part 80 can be rotated in both directions (front and back, left and right, etc.) relative to the first body part 70, but the hair clipper may also be one in which the second body part can be rotated in only one direction (front only, left only, etc.) relative to the first body part.
[0169] It is also possible to make a hair clipper in which the second main body portion 80 is detachably attached to the first main body portion 70.
[0170] Furthermore, the specifications of the first main body portion, the second main body portion, and other details (shape, size, layout, etc.) can also be changed as appropriate. [Industrial Applicability]
[0171] As described above, the cutting device according to the present disclosure can further improve operability, and can therefore be applied to hair clippers for cutting human hair, pet hair clippers for cutting pet hair, and the like. [Explanation of symbols]
