Description

  The present invention relates to a barber for barber.

  The barb for scissors is for cutting the hair so that it is thinned out. Basically, one cutting blade part of the two scissors members is formed in a comb-like shape, and a blade is provided at the tip of each comb tooth. The hair that is formed and part of the hair escapes into the gap between the comb teeth when the hair is cut, and the hair sandwiched between the comb-like blade portion and the opposing blade portion is cut.

  By the way, the cross-section of the blade part of the barber for scissors has a so-called clam shape, and the back surface of the blade part (blade-grinding surface) is shallow and the surface of the blade part is an inclined surface from the peak to the blade edge. In general, the shape of the peak part is a R surface (patent document 1) or a cliff (patent document 2) from the blade surface to the peak part.

  And the part (ridge back side part) from a blade part back surface to a peak part is not clear in the state of illustration, but chamfering by grinding | polishing is common.

  Moreover, although the cross-sectional shape of the comb bar which comprises a comb blade part is generally square, it is also proposed to make it the polygonal shape which chamfered each corner | angular part (patent document 3).

FIG. 4 of Japanese Patent Laid-Open No. 2001-149668. FIG. 4 of Japanese Patent Application Laid-Open No. 8-299622. FIG. 4 of JP-A-10-174788.

  When cleaning the firewood, the wiping with a cloth covers the peak with a cloth and wipes off the dirt from the pivotal part toward the blade edge. At this time, since the back side portion of the blade peak is a square surface, the touch is not necessarily good. Further, when the heel is housed in the sheath, there is also a problem that the insertion into the sheath is smooth because the ridge back side portion has a square shape.

  Further, the comb bar constituting the comb blade portion has an effect of not damaging the hair (non-cutting target hair) that has entered the gap between the comb teeth when the corner portion is chamfered as proposed in Patent Document 3 above. Considering its own elasticity, simply chamfering cannot solve the problem that the corners after chamfering come into contact with and rub against the hair.

  Therefore, the present invention proposes a barber's scissors that solve the problems in the ridges of the scissors and the chamfered portions of the comb bars.

  The barb for scissors according to the present invention is composed of two scissors members provided with a finger hole part on the end side and provided with a blade part having a cross section gradually thinned from the peak part to the blade edge on the other side. The members are crossed and the crossing part is pivoted. The blade part of one hook member is a comb blade part and the other is a narrow rod-like blade part. In a barber shears formed in a shape that protrudes from the edge of the blade and is exposed, the exposed ridge when the two blades are closed is formed in an arcuate surface that straddles the front and back.

  Therefore, since the ridges of the blade part are both R surfaces, the fingertip feels good and cleans when wiping away the ridge part from the pivotal part to the blade edge with a cloth when cleaning the shears. It is easy to insert the bag into the sheath smoothly when the bag is stored in the sheath.

  The present invention (Claim 2) is characterized in that both side corners of each comb bar portion constituting the comb blade portion are chamfered in an R shape.

  Accordingly, since the hair (non-cutting target hair) that has entered the gap between the comb teeth comes into contact with the R-shaped chamfered portion, there is no problem of being rubbed and damaged.

  In the present invention, by forming a peak portion of a predetermined range in the blade portion of the firewood on the R-shaped arc surface straddling the front and back, the blade portion can be easily maintained, and the sheath can be stored smoothly. Further, the corner portion of the comb bar constituting the comb blade portion is formed on the R surface, thereby preventing the hair from being damaged during use.

  Next, an embodiment of the present invention will be described. The scissors shown in the embodiment is basically the same as the previous one, and two scissors members A are provided with finger holes 1a, 1b on one end side and blades 2a, 2b on the other side. , B, crossing both hook members A, B at the center, and pivoting the crossing part C. The blade part of one hook member A is the comb blade part 2a, and the other hook member B The blade portion is formed as a narrow rod-shaped blade portion 2b, and when the two blade portions 2a and 2b are closed, the ridge portions 21a and 21b are formed so as to protrude from the edge of the other blade portion and be exposed.

  Furthermore, each peak part 21a, 21b of the said blade part 2a, 2b is formed in the arcuate surface ranging over the front and back in the range (L range) exposed when the collar is closed. Specifically, as illustrated in FIG. 3B, the back side portion (X1 portion) of the ridge portion in the cross-section of the blade portion of the conventional scissors is the large R surface (X portion) in FIG.

  Further, each comb bar 22 of the blade portion 2a has a corner portion facing the comb tooth gap 23 as an R-shaped arcuate surface (Y portion). That is, the cross section has a rounded corner shape, which is clear as compared with the conventional device in which the corner Y1 in FIG. 4B is not chamfered at all and the chamfered corner Y2 described in Patent Document 3 shown in FIG. It is what.

  The arcuate surface Y can be easily formed by using a rotating grindstone Z whose outer peripheral grinding surface has a concave arcuate surface. Of course, after roughing as shown in FIG. 4C as rough polishing, an arcuate surface may be formed.

  Thus, when hair is prepared by attaching fingers to the finger holes 1a and 1b in the same manner as a general barb for scissors, a part of the hair escapes to the comb-tooth gap 23, and the mowing is realized. In particular, even if the hair that has escaped into the comb-tooth gap 23 comes into contact with the peripheral surface of the comb bar 22 and rubs due to relative movement with the wrinkles, the hair is not damaged because the portion is an R-shaped surface. . In addition, when the comb bar side surface 24 of the comb bar 22 is formed in a bulging arc-shaped surface as shown in FIG. 5, the subsequent occurrence of hair is further suppressed in combination with the arc-shaped surface Y.

  Moreover, since the ridges 21a and 21b projecting from the edge of the opposing blades 2a and 2b are R surfaces across the front and back surfaces, the ridges 21 are stained from the pivoted part to the cutting edge with cloth. When wiping, the fingertip feels good and dirt is easy to remove. Further, when the flange members A and B are closed, the R surface is limited to the exposed peak portion, so the back surface of the blade edge portion is in close contact with the back surfaces of the opposed blade portions 2a and 2b. Since the edge of the blade is not lifted, insertion into the sheath can be performed smoothly even when the heel is stored in the sheath.

1 is an overall view of an embodiment of the present invention (opening state of a flange member). FIG. In the cross-sectional view of the blade part, (a) shows an example of the present invention (b) shows a conventional example. In the longitudinal section of the comb blade portion, (a) shows an example of the present invention (b) and (c) shows a conventional example. The cross-sectional view of another example of the blade part.
