  An embodiment of the present invention which is considered to be suitable will be briefly described with reference to the drawings showing the operation of the present invention.

  The comb blade 4 is inserted into the hair and the hair 6 sandwiched between the blade 2 and the comb blade 4 is cut. At this time, the hair supported and held in the concave portion 9 of the inclined edge portion 8 of the tip edge of the comb blade 3 is cut by the blade edge 1 of the blade plate 2 and the hair (groove bottom portion) entered into the groove between the comb blades 3. Hair collected in 6) is not cut.

  Specifically, the hair placed on the inclined edge 8 of the tip edge of each comb blade 3 is pushed and guided to the concave portion 9 with the closing movement of the blade plate 2, and according to the depth of the concave portion 9. An amount of hair is supported and cut in this recess 9. In the present invention, each comb blade 3 is set to be widened so that the distal end side is wider than the proximal end side, and the wide edge of each comb blade 3 extends along the longitudinal direction of the comb blade plate 4. Inclined edge portions 8 that are inclined downward from the base side of the comb-like blade plate 4 toward the blade edge side at an angle of 10 to 25 degrees with respect to the reference line are provided, and 0.03 mm to 0 is provided on each of the inclined edge portions 8. By forming the concave portion 9 having a depth of 15 mm, as shown in FIGS. 1 and 2, the small concave portion 9 provided on the inclined edge portion 8 that gently inclines on the wide tip edge of the comb blade 3 Further, it is possible to capture and cut a small amount of hair out of a large amount of hair placed on the tip edge of the comb blade 3, and to perform cutting with the simplest opening and closing operation.

  Further, according to the present invention, the amount of hair to be cut at the tip edge of each comb blade 3 can be set by appropriately setting the number of juxtaposed recesses 9 and the depth thereof, and the inclined edge portion 8 of each comb blade 3 can be set. By making the angle constant, the amount of hair cut by each comb blade 3 can be made constant, and the resistance at the time of cutting the hair on the blade tip side and the root side can be made uniform. There is no difference between them, it is easy to grasp the amount of hair that can be cut, it is possible to make a good cut with a uniform operation without the need to change the way of opening and closing depending on the part, compared to conventional sukiyaki, It becomes possible to cut as easily as the operator wishes.

  That is, in the conventional plow, as shown in FIG. 3, the inclination angle of the inclined edge 22 of the tip of the comb blade 23 of the comb-shaped blade plate 21 corresponding to the inclined edge portion 8 of the present invention is the blade edge side of the hook. In many cases, it is set to be large, and there is a tendency for resistance when cutting hair with the comb blade 23 on the base side to be larger than the tip side (the amount of hair to be cut increases), and a uniform resistance feeling I couldn't cut it. In the figure, Y, Y ′ and Y ″ are reference lines (parallel lines) parallel to the longitudinal direction of the comb-shaped blade plate 21 (upper and lower sides of the square center hole 24).

  In this regard, according to the present invention, as described above, it is possible to cut a constant amount of hair on both the blade tip side and the root side of the scissors and perform a cut with a uniform resistance, which can be handled more easily.

  Specific embodiments of the present invention will be described with reference to the drawings.

  In this embodiment, a blade plate 2 having a blade edge 1 and a comb-shaped blade plate 4 in which a large number of comb blades 3 are projected in a juxtaposed manner through grooves are supported at the intersection of both blade plates 2 and 4. The hair is pivotally attached by a screw 13 so as to be freely opened and closed, and the hair supported on the tip edge of the comb blade 3 is cut by the blade edge 1 of the blade plate 2, and the hair collected on the groove bottom 6 between the comb blades 3 Is a plow configured not to be cut by the blade edge 1 of the blade plate 2, and the groove bottom portion 6 between the comb blades 3 is wider than the groove opening portion 7. The comb blade 3 is set to be widened so that the distal end side is wider than the proximal end side, and the wide edge of each comb blade 3 is set to 10 with respect to a reference line parallel to the parallel arrangement direction of the comb blades 3. Each of the inclined edges 8 is provided with an inclined edge 8 inclined downward from the root side of the comb-shaped blade plate 4 toward the edge of the blade at an angle of ˜25 °, and 0.03 mm to 0.15 mm. A concave portion 9 having a depth is formed, and the hair supported and held by the concave portion 9 is cut by the blade edge 1 of the blade plate 2, and the inclination angle of each inclined edge portion 8 is set to the reference line. So that the amount of hair (hair amount) cut at each comb blade 3 is constant and the resistance at the time of cutting the hair is uniform at each comb blade 3. It is composed.

  Specifically, in this embodiment, as shown in FIGS. 1 and 2, the inclination angle of each inclined edge 8 is unified to a predetermined angle α, and a plurality of the recesses 9 are arranged in parallel with the inclined edge 8. The plurality of recesses 9 on each comb blade 3 are set to the same depth β.

  Further, a flat bottom edge 10 is provided at the groove bottom portion 6 between the comb blades 3 so as to be substantially parallel to the direction in which the comb blades 3 are juxtaposed, so that the groove bottom portion 6 has a wide flat bottom shape instead of a round bottom shape. A concave curved corner edge 11 that smoothly connects the side edge of the comb blade 3 and the flat bottom edge is provided on the side edge base end side of the left and right comb blades 3 adjacent to the groove. In the figure, reference numeral 14 is a thumb hole, 15 is a ring finger hole, and 16 is a square center hole.

  Specifically, in this embodiment, the groove bottom 6 has a flat bottom shape that is wider than the groove opening 7 (wider from the groove opening 7 toward the groove bottom 6), and enters from the groove opening 7. When the hair smoothly contacts the groove bottom 6 in a dispersed state and the comb blade 4 is pulled out of the hair, the hair is flat in a state of being widely dispersed from the flat bottom edge 10 to the concave curved corner edge 11. The hair can be pulled out along the bottom edge 10 and the concave curved corner edge 11, and the hair can be pulled out very efficiently and smoothly. The hair that has entered between the comb blades 3 can be smoothly pulled out while being cut into two pieces, and the wrinkles can be put into and taken out from the hair faster, so that the workability of the cut can be greatly improved without damaging the hair. .

  Each part will be specifically described.

  A large number of comb blades 3 project from the comb-like blade plate 4 in a juxtaposed manner in a state of being curved along the opening and closing track of the blade edge of the blade plate 2 pivotally attached to the comb-like blade plate 4 at the crossing portion. . The side edges of the comb blade 3 are arranged so that the comb blade 3 is gradually widened from the proximal end side toward the distal end side, from the comb blade distal end side toward the comb blade proximal end side, The comb blade 3 is set to be curved in the same direction (blade edge side) so as to be gradually narrowed.

  Therefore, the groove between the comb blades 3 gradually becomes wider from the groove opening 7 side toward the groove bottom 6 side, and the hair that has entered between the comb blades 3 does not stagnate from the groove opening 7 to the groove bottom 6. Can be moved to. Further, since the groove bottom portion 6 becomes wider, the capacity of the groove bottom portion 6 increases accordingly, and even when a large number of hairs enter, it is difficult to be densely packed, and there is no resistance when pulling out the blades 2 and 4 in a closed state. The hair can be smoothly pulled out from the groove bottom 6.

  The groove bottom portion 6 is composed of a flat bottom edge portion 10 and a concave curved corner edge portion 11 which are flat in a direction substantially orthogonal to the hair entering direction from the groove opening 7. Accordingly, when the hair enters the groove, the hair naturally moves to the groove bottom 6 due to its own weight, and since the groove bottom 6 is wide and flat and has no irregularities that hinder the movement of the hair, the hair naturally disperses in the groove bottom 6. It will be in contact with the whole.

  That is, the groove bottom portion 6 has a flat bottom shape with rounded corners (curved R shape), so that when the comb-shaped blade plate 4 is pulled out from the hair, the groove bottom portion 6 becomes a groove between the comb blades 3 due to the presence of the flat bottom edge portion 10. The hair that has entered can be dispersed and moved to the left and right along the flat bottom edge 10 so that it does not concentrate at the central part, and comes out in a state of being widely dispersed on the flat bottom edge 10, and is recessed along the side edge of the comb blade 3. The hair that has reached the curved corner edge 11 and the hair that is about to spread along the flat bottom edge 10 can be satisfactorily pulled out without the concave curved corner edge 11 being caught. Can be removed.

  The width of the flat bottom edge 10 of the groove bottom 6 is about 55% of the width of the groove bottom 6 (maximum width of the groove). The width of the flat bottom edge 10 varies depending on the parallel pitch of the comb blades 3, but in order to obtain a smooth pulling comfort, the ratio of the width of the groove bottom 6 to the width of the flat bottom edge 10 is 4: 1 or more. More preferably, it has been confirmed by various experiments that it is desirable to set it to 2: 1 or more (50% or more of the width of the groove bottom 6) (when the flat bottom edge 10 is too narrow, a concave curved corner edge) 11 becomes larger, and movement to both sides of the hair is hindered.)

  An inclined edge 8 is provided at the tip edge of the comb blade 3 of the comb-shaped blade plate 4. The inclined edge portion 8 is a reference line (parallel line in the longitudinal direction of the comb-like blade plate 4, specifically parallel to the longitudinal direction of the comb-like blade plate 4. X, X ′, X ′ in the figure. ′ And X ′ ″) are inclined downward from the root side of the comb-shaped blade plate 4 toward the blade edge side at an angle α of 10 to 25 °. In this embodiment, the reference line parallel to the longitudinal direction of the comb-shaped blade plate 4 is a vertical line A passing through the most distal point and the most proximal end point of the comb-shaped blade plate 4 as shown in FIG. , B and a line C orthogonal to each other. Specifically, in this embodiment, the line C is parallel to the parallel upper and lower sides of the square center hole 16. Further, for example, a reference line parallel to the juxtaposed direction of the comb blades 3, specifically, the plural juxtaposed directions (two or three) on the root side may be used.

  A plurality of (in this embodiment, five) recesses 9 having a depth β of 0.03 mm to 0.15 mm are arranged in parallel near the cutting edge side of each inclined edge 8 of each comb blade 3. The recess 9 has a curved arc shape. Further, the number and depth of the concave portions 9 of each comb blade 3 and the arrangement position (tip edge shape of the comb blade 3) in the inclined edge portion 8 are made the same.

  If the inclination angle of the inclined edge 8 is less than 10 °, too much hair stays at the leading edge, and if it exceeds 25 °, too little hair stays at the leading edge, which is not preferable. In addition, if the depth of the concave portion 9 is less than 0.03 mm, the amount of hair that can be supported and held becomes too small, and if it exceeds 0.15 mm, the amount of hair that can be supported and held becomes too large.

  Further, a protruding edge portion 12 that is inclined at a stronger inclination angle than the inclined edge portion 8 is provided at the base side portion of the inclined edge portion 8.

  Accordingly, the hair placed on the tip edge of the comb blade 3 is pushed by the blade edge 1 with the closing movement of the blade plate 2, and the like, and the concave portion 9 on the base side of the protruding edge portion 12 and the inclined edge portion 8. The flat slanted portion that does not exist is slid down and drawn into the concave portion 9, and the portion that cannot be stored in the concave portion 9 is discharged into the groove between the comb blades 3, and the hair supported and held in the concave portion 9 is removed from the blade plate. It is cut by two blade edges 1.

  Further, the inclination angle of each inclined edge 8 is set to be the same angle with respect to the reference line, the amount of hair to be cut is constant, and the resistance when cutting the hair is uniform in each comb blade 3 It is trying to become.

  The cutting edge line (virtual line) connecting the tips of the protruding edges 12 of each comb blade is set so as to gently and smoothly descend from the root side to the tip side. Here, in the past, the plow was designed based on the cutting edge line (blade line). However, the present invention was designed based on the center hole 16, and in this respect is the conventional plow. The design philosophy is completely different.

  Further, it has been confirmed that the inclined edge portion 8 is preferably provided in a range of 80% or more and less than 95% of the tip edge of the comb blade 3.

  Therefore, in this embodiment, the amount of hair cut by each comb blade is constant, and the plow is easy to handle and can be cut with uniform resistance between the tip side and the base side of the heel and has excellent practicality.

  Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
