Japanese Patent No. 3015366 (paragraph number 0019, FIG. 2)

  In the above clippers, the scissors cutting is performed with the second shearing blade protruding forward from the cutting edge portion of the first shearing blade, so that the cutting edge portion of the second shearing blade can be clearly seen and cut at the hairline. And finish cutting can be performed accurately. However, since the second shearing blade moved to the operating position protrudes greatly beyond the cutting edge portion of the first shearing blade, the external force moment increases when a drop impact acts on the cutting blade portion. Inevitably, the blade holder and body case are easily damaged. There are also disadvantages that tend to give fear to third parties.

  In order to reciprocate the second shear blade, the rotational power of the motor is converted to reciprocating power by a dedicated vibrator, and the reciprocating motion of the vibrator is transmitted to the movable blade via the drive lever. Becomes complicated and the overall cost of the clippers increases.

  An object of the present invention is to provide a robust clipper that is not easily damaged even when a drop impact acts on the cutting blade portion by optimizing the posture switching structure of the second shearing blade unit. An object of the present invention is to provide a hair clipper capable of cutting hair and wrinkles in a state in which the cutting edge portion of the second shearing blade unit is clearly viewed, and thus can accurately perform cutting at the hairline and finishing cutting. An object of the present invention is to provide a clipper capable of simplifying the drive structure of the second shear blade unit and reducing the overall cost accordingly.

The clipper of the present invention includes a first shear blade unit 3 including a saw blade-shaped fixed blade 17 and a saw blade-shaped movable blade 18 that can reciprocate along the surface of the fixed blade 17, and a saw blade-shaped fixed blade. Two shear blade units 3 and 4 of the second shear blade unit 4 including a blade 35 and a saw blade-like movable blade 36 that can reciprocate along the surface of the fixed blade 35 are provided. First shearing blade unit 3 is placed on the front of the body case 1, and is further second shearing cutter unit 4 is arranged on the front upper surface of the main body case 1. The first shear blade unit 3 is disposed at the front portion of the main body case 1 with the cutting tip associated with the overlapping portion of the fixed blade 17 and the movable blade 18 rising and inclined. The second shearing blade unit 4 has a standby posture in which the cutting blade portion retracts backward from the cutting blade portion of the first shearing blade unit 3 and lies on its side, and moves forward from the standby posture to the second shearing blade unit. 4 is supported so that it can be switched to a use posture that stands up and inclines in the same direction as the first shear blade unit 3. Therefore, the cutting edge tip of the second shearing blade unit 4 in the use posture is located in the vicinity of the vertical plane V passing through the cutting blade tip of the first shearing blade unit 3 . The second shear blade unit 4 in the standby posture is held in a state where the unit center axis P is inclined downward toward the first shear blade unit 3 as shown in FIG.

  As shown in FIG. 6, the inclination angle θ2 of the cutting blade surface of the second shearing blade unit 4 in the use posture can be set to be substantially the same as the inclination angle θ1 of the cutting blade surface of the first shearing blade unit 3.

  A passive arm 41 that inherits the reciprocating power is provided on the lower surface side of the second shear blade unit 4, and in a state where the second shear blade unit 4 is switched to the use posture, the passive arm 41 is the driving claw 22 of the first shear blade unit 3. It can be configured to be able to engage with.

  Inside the guide frame 29 arranged on the front upper surface of the main body case 1, there are a second shearing blade unit 4, an operation knob 31 for operating the second shearing blade unit 4 between a standby posture and a use posture, The second shear blade unit 4 and the joint piece 32 that connects the operation knob 31 in a refractive manner are incorporated. On the left and right side walls of the guide frame 29, a guide groove 61 for moving and guiding a slide pin 49 provided on the blade holder 34 of the second shear blade unit 4 and a regulation recess 62 continuous with the guide groove 61 are formed. In a state where the second shearing blade unit 4 is switched to the use posture, the slide pin 49 can be dropped into the restriction recess 62 and engaged.

  In the clipper of the present invention, the second shear blade unit 4 disposed on the upper surface of the front portion of the main body case 1 is erected and inclined in the same direction as the first shear blade unit 3 in the use posture, and further the second shear blade unit in the use posture. The cutting edge tip of 4 was positioned in the vicinity of the vertical plane V passing through the cutting edge tip of the first shearing blade unit 3. That is, unlike the conventional clippers of this type, the second shearing blade unit 4 is made to stand by inclining the cutting edge tip of the second shearing blade unit 4 above the cutting edge tip of the first shearing blade unit 3. The second shearing blade unit 4 can be used independently while avoiding a large protrusion from the cutting blade portion of the first shearing blade unit 3.

  As described above, if the cutting edge tip positions of both units 3 and 4 are aligned, the chance that an external force such as a drop impact will act on the cutting edge portion of the second shearing blade unit 4 can be halved. Compared with this, the projecting dimension of the second shearing blade unit 4 from the main body case 1 can be made smaller. Therefore, it is possible to reliably prevent an excessive external force moment from acting on the second shearing blade unit 4 or the main body case 1 and breakage. A hard and robust hair clipper is obtained. Furthermore, in a state where the cutting edge portion of the second shearing blade unit 4 is clearly visually observed, cutting at the hairline or hairline or finishing cutting can be performed accurately. Moreover, since the cutting edge tip positions of both units 3 and 4 are aligned, the main body case 1 is grasped and held when the first shearing blade unit 3 is used and when the second shearing blade unit 4 is used. There is no need to change the position, and hair and wrinkles can be cut while holding the fixed position, so the usability of clippers can be improved.

  In the standby posture, when the unit center axis P of the second shearing blade unit 4 is inclined downward toward the first shearing blade unit 3, when cutting hair or wrinkles using the first shearing blade unit 3, The second shearing blade unit 4 is prevented from getting in the way, and hair and wrinkles can be cut lightly and quickly in the same manner as a clipper that does not include the second shearing blade unit 4. Further, as shown in FIG. 5, when the cutting edge portion of the second shearing blade unit 4 is positioned within the outline of the main body case 1 in the standby state, the second shearing blade unit 4 is used when cutting hair and wrinkles. Further, it is possible to more reliably prevent obstruction, and it is possible to prevent the blade edge portion from being damaged by receiving the drop impact by the main body case 1.

  According to the clipper in which the inclination angle θ2 of the cutting blade surface of the second shearing blade unit 4 in the use posture and the inclination angle θ1 of the cutting blade surface of the first shearing blade unit 3 are set substantially the same, each shearing blade unit 3・ When using 4, there is no need to change the position to hold and hold the main body case 1, and the hair case and the wrinkle can be accurately positioned with the same angle of inclination when the hair clipper is applied to the skin. It can be cut and the usability of clippers can be further improved.

  A passive arm 41 is provided on the lower surface side of the second shear blade unit 4, and the passive arm 41 is engaged with the drive claw 22 of the first shear blade unit 3 in a state where the second shear blade unit 4 is switched to the use posture. According to the clipper configured to inherit the reciprocating motion by combining the two, the structure for driving the second shear blade unit 4 can be simplified, and the overall cost of the clipper can be reduced accordingly. Since the reciprocating power is transmitted from the first shear blade unit 3 only when the second shear blade unit 4 is used, power loss when using the first shear blade unit 3 can be reduced. As the drive structure is simplified, the failure rate can be reduced and the weight can be reduced.

  A guide frame 29 is arranged on the upper surface of the front part of the main body case 1, and the second shear blade unit 4, the operation knob 31, and a joint piece 32 for connecting both of these 4 and 31 are incorporated in the guide frame 29. According to the clipper configured to move and guide the slide pin 49 of the blade holder 34 with the guide groove 61, at the connecting portion between the second shear blade unit 4 and the joint piece 32, and the operation knob 31 and the joint piece 32. The second shear blade unit 4 and the joint piece 32 can be refracted. That is, in the state where the second shear blade unit 4 is switched to the use posture, the second shear blade unit 4 can be held and fixed in a stable state while being largely tilted upright. Further, the slide pin 49 of the blade holder 34 is lowered and engaged with the restriction recess 62 in the use posture, so that the second shear blade unit 4 can be reliably prevented from returning to the standby posture due to external force. The cutting at the hairline and the hairline by the 2-shear blade unit 4 and the finish cutting can be accurately performed in a stable state.

  As described above, when the guide groove 61 is formed in an inverted character shape, the second shear blade unit 4 only moves forward while the pair of front and rear slide pins 49 move along the curved groove 61a. However, when the front slide pin 49 enters the turning groove 61b, the second shearing blade unit 4 advances while the cutting blade portion stands up in a direction to float away from the main body case 1.

  Then, as shown in FIG. 1, in a state where the front slide pin 49 falls into and engages with the restriction recess 62 and the second shear blade unit 4 is completely switched to the use posture, the first shear blade unit 3 and Similarly, the blade holder 34 is inclined upward (standing upright) toward the cutting edge portion, and the lower surface of the rear portion of the blade holder 34 is held by the guide frame 29. At the same time, the passive arm 41 is engaged between the pair of drive claws 22 (FIG. 6). reference).

  As shown in FIG. 6, the cutting edge tip of the second shearing blade unit 4 when switched to the use posture is located on a vertical plane V that passes through the cutting edge tip of the first shearing blade unit 3. Thus, when the cutting edge tip positions of both units 3 and 4 are aligned, the chance that an external force such as a drop impact acts on the cutting edge portion of the second shearing blade unit 4 can be halved.

  Furthermore, although the hair and the heel can be cut with the cutting edge portion of the second shearing blade unit 4 clearly observed, the projecting dimension of the second shearing blade unit 4 from the main body case 1 is larger than that of the conventional clipper. Can be small. Therefore, it is possible to reliably prevent an excessive external force moment from acting on the second shearing blade unit 4, the guide frame 29, or the main body case 1, and a robust clipper that is not easily damaged can be obtained.

  Moreover, since the cutting edge tip positions of both units 3 and 4 are aligned, the main body case 1 is grasped and held when the first shearing blade unit 3 is used and when the second shearing blade unit 4 is used. There is no need to change the position, and hair and wrinkles can be cut while holding the fixed position.

  When the second shearing blade unit 4 is switched to the use posture, the inclination angle θ2 of the cutting blade surface with respect to the center axis of the clipper is 30 degrees, but the inclination angle of the cutting blade surface of the second shearing blade unit 4 ( 30 degrees) and the inclination angle (36 degrees) of the cutting blade surface of the first shear blade unit 3 are substantially the same, when the shear blade units 3 and 4 are used in the same manner as described above, It is not necessary to change the position for grasping and holding 1, and hair and wrinkles can be cut accurately with the inclination angle of the body case 1 when the clipper is applied to the skin surface being substantially the same.

  In the state where the second shearing blade unit 4 is switched to the use posture, the slide pin 49 falls into and engages with the regulating recess 62, so that it is ensured that the second shearing blade unit 4 receiving the external force returns to the standby position side. Therefore, it is possible to accurately perform the cutting and finishing cutting at the hair and wrinkle by the second shearing blade unit 4 in a stable state.

  As shown in FIG. 5, in the state where the second shearing blade unit 4 is switched from the use posture to the standby posture, the second shearing blade unit 4 is accommodated in the paragraph surface 60 of the pocket 30 of the guide frame 29, and the center of the unit. Since the axis P is held in a state of being inclined downward toward the first shearing blade unit 3, when the first shearing blade unit 3 is used, the second shearing blade unit 4 obstructs the cutting of hair and wrinkles. Can be prevented. Further, in the standby state, the cutting edge portion of the second shearing blade unit 4 is located within the front outline of the guide frame 29, so that it is less likely to get in the way and damage to the cutting edge can be well prevented.

  When cutting hair or wrinkles with the first shearing blade unit 3, the length of the hair or wrinkles after cutting can be made constant by attaching the cap 9 for hair cutting to the head portion 8. By shifting the mounting position of the cap 9 with respect to the head portion 8 back and forth, the length of the hair and wrinkles after cutting can be changed to a large or small size. For this purpose, a front and back adjustment mechanism including an adjustment ring 10 is incorporated in the main body case 1.

  An internal gear 75 is formed on the inner surface of the adjustment ring 10, and the adjustment screw shaft 72 is rotated by transmitting the rotational operation of the internal gear 75 to a passive gear 76 provided at the rear end of the adjustment screw shaft 72. can do. The adjustment screw shaft 72 is pivotally supported by a wall that sandwiches the passive gear 76 in the front-rear direction, and can be freely rotated but cannot be moved back and forth. Therefore, when the adjustment screw shaft 72 is rotated, the female screw body 73 and the adjustment arm 74 can move back and forth according to the amount of rotation of the adjustment screw shaft 72 to change and adjust the front and rear position of the cap 9.

  As shown in FIG. 7, the drive mechanism for the adjustment ring 10 includes a plate spring click spring 80 fastened and fixed to the inner frame of the drive unit 2 with screws 79, and the inner surface of the adjustment ring 10 at equal intervals. It consists of twelve click recesses 81 formed in a recess.

  At the free end of the click spring 80, a partially spherical projection 82 is formed to drop into and engage with the click recess 81. By rotating the adjustment ring 10 by an amount corresponding to the adjacent pitch of the click recess 81, the front / rear position of the cap 9 can be finely adjusted with a minimum feed amount of 1/12 of the screw pitch of the adjustment screw shaft 72. An anti-slip groove 83 is formed on the peripheral surface of the adjustment ring 10.

  When the cap 9 is used in combination, the cylinder base 65 is attached to the head 8 with the second shearing blade unit 4 switched to the standby position. In this attached state, the upper wall of the cylinder base 65 is the blade. Cover the upper surface of the holder 34. Therefore, even if the operation knob 31 is slid forward, the blade holder 34 is received by the tube base 65, and therefore the operation knob 31 cannot be slid. That is, the posture of the second shearing blade unit 4 cannot be switched in a state where the cap 9 is attached to the head portion 8.

  In addition to the above embodiment, when the front case 12 is constituted by a pair of left and right divided cases, the guide frame can be formed integrally with the front case 12. The operation knob 31 and the joint piece 32 can be omitted. In that case, the second shear blade unit 4 may be directly operated to switch between the standby posture and the use posture.
