Description

The present invention relates to the technical field of barber / beauty salons.

  Conventionally, Japanese Laid-Open Patent Publication No. 2000-12478 has been disclosed as a scissors (barber / beauty), but the stationary blades and the moving blades constituting the scissors are fastened and pivoted via bolts and fastening nuts. ing.

  Therefore, among the two blade bodies, the moving blade cuts the hair while rotating around the required bolt and the fastening nut.

  Furthermore, as a conventional hairdressing scissor, Japanese Patent Laid-Open No. 8-266752 is disclosed, but the two blade bodies (moving blade 1 and stationary blade 2) constituting the hairdressing scissors are interposed via screws. It is pivotably attached to it.

  Therefore, among the two blades, the moving blade cuts the hair while turning around the bolts required to cut the hair.

  Further, as a conventional barber and beauty salon, Japanese Utility Model Publication No. 5-5077 published utility model gazette has been disclosed, but a pair of barb constituting members 4a and 4b constituting the barber and beauty salon are relatively swung by bolts and nuts 5. It is connected freely.

  Therefore, the heel constituting member 4a corresponding to the moving blade constituting the hairdressing and beauty candy cuts the hair while rotating around the bolts and nuts 4a and 4b.

  As described above, in each of the three disclosed barbers and beauty salons, both blade bodies (static blade and moving blade) are pivotally attached with a screw or the like, and the moving blade is a screw or the like at the pivot point. From this point, hair is cut while rotating.

  Therefore, since the range of the blade part which frequently hits at the time of cutting hair among both blades is limited, the sharpness becomes a cause of inhibition in a short time.

  Furthermore, the previously disclosed barber / beauty salon has a structure in which the movement of the moving blade rotates around the pivot point of the screw, so that the two blades receive the resistance of the hair when cutting the hair and cut the hair. It was difficult.

Further, in the above-described conventionally disclosed barber and beauty salon, since the moving blade rotates around the pivoting portion such as a screw required, the range of the blade portion hitting at the time of cutting is limited, the degree of wear of the blade portion is accelerated, and the sharpness is increased. Synergistically, the both blades are remarkably affected by the resistance of the hair when the hair is cut, and the above-mentioned sharpness is deteriorated.

  Furthermore, the present invention has an effect that the hair is not caught when the hair is cut.

  Since the embodiments related to the inventions according to claims 1 to 5 of the present invention are common, they will be described collectively as follows.

  In the drawings, a is a stationary blade constituting the hairdressing and beauty salon of the present invention, and b is a moving blade corresponding to the stationary blade a. The double blades a and b have the following configuration.

  Hereinafter, the configuration of the stationary blade a will be described. Reference numeral 1 denotes a through hole into which a required bolt 4 formed from the front side 2 to the back side 3 is inserted.

Reference numeral 5 denotes an elongated and curved groove that is inclined in the direction of the bottom surface 7 a of the handle 7 from the peak 6 in the vicinity of the through hole 1 in the back surface 3 constituting the stationary blade a. The width of the groove 5 is narrower than the width of the stationary blade a and has the same width.

  Next, the configuration of the moving blade b will be described.

  The moving blade b has a length for penetrating a fastening nut 11 to which the bolt 4 required to be inserted into the through hole 1 of the stationary blade a is screwed from the front surface side 9 to the back surface side 10 constituting the moving blade b. Hole 8 is formed.

  The elongated hole 8 penetrates the fastening nut 11 and guides the fastening nut 11, and a portion near the cutting edge 12 a constituting the moving blade b and a portion near the handle 13 are A lower bulge portion 8c is formed which has the same width, bulges the left side and the right side in a heel-curved shape, and bulges the lower portion 8b constituting the elongated hole 8 in the direction of the heel upper portion 8a (FIG. 8). ).

  And the said long hole 8 is made into the shape which the insertion part 11b of the said fastening nut 11 can insert.

  Further, according to the present invention, a surface side recess 16 having a diameter larger than that of the long hole 8 is formed on the surface side 9 of the moving blade b. A head 11 a of the fastening nut 11 is fitted in the recess 16.

  Further, according to the present invention, the back surface side concave portion 17 is formed on the back surface side 10 of the moving blade b as a hair escape pot having a diameter larger than that of the long hole 8.

  Reference numeral 18 denotes a guide pin that is inserted into the groove 5 of the stationary blade a that is formed in a protruding shape in the vicinity of the back surface side concave portion 17 near the handle 7b of the moving blade b. The height of the protruding portion of the pin 18 is slightly shorter than the depth of the concave groove 5 of the stationary blade a so that a gap is not formed when the pin 18 is in close contact with the stationary blade a. The reason for this is that when the guide pin 18 is inserted into the concave groove 5, if it is longer than the depth of the concave 5, the blades a and b are lifted up without being brought into close contact with each other, and a gap is formed. This is because hair cannot be cut smoothly.

  Reference numeral 11a denotes a head of a fastening nut 11 which is screwed to the bolt 4 and penetrates through the long hole 8 of the moving blade b. The diameter of the head portion 11a of the nut 11 is slightly smaller than the diameter of the surface-side recess 16 and does not protrude from the surface side of the moving blade b. Further, a female screw 19 into which the bolt portion of the required bolt 4 is screwed is formed inside the insertion portion 11c opposite to the head portion 11a.

  Furthermore, the cap c is used in the inventive hairdressing and beauty salon.

  The cap c has a diameter larger than that of the surface-side concave portion 16 formed on the surface side 9 of the moving blade b, and is fitted into a cap-inserting concave portion 16a of a size that encloses the guide pin 18 and is capped.

  And the protrusion part 23 with the recessed part 24 inserted in the said guide pin 18 is formed in the back surface part 22 of the said cap c when the cap c is inserted in the said cap insertion insertion recessed part 16a.

  Further, the relationship between the cap insertion recess 16a and the cap c is that when the cap c is inserted into the cap insertion recess 16a, the guide pin 18 is inserted into the recess 24 of the protrusion 23, and The surface portion 21 of the cap c slightly protrudes from the surface portion 9 of the moving blade b or is in the same plane.

  The cap c is usually made of transparent plastic.

  When assembling the stationary blade a and the moving blade b having the above-described configuration, the pin 18 on the side of the moving blade b is inserted into the concave groove 5 on the stationary blade a side, and the required bolt 4 is inserted into the through hole 1. The bolt portion of the main bolt 4 inserted as described above is screwed to the female screw 19 of the fastening nut 11 inserted from the elongated hole 8 of the stationary blade b. At that time, the head 11a of the fastening nut 11 is inserted into the front surface side recess 16 and does not fly out from the front surface side 9 of the moving blade b.

The cap c provided separately is inserted into the cap insertion recess 16a having a larger diameter than the surface side recess 16 of the stationary blade a assembled as described above.

The guide pin 18 is inserted into the cap c recess 24 and is not easily removed.

  When the stationary blade a and the moving blade b are assembled as described above and the both blades are fully developed, the pin 18 guides the inside of the concave groove 5, and at the same time, the head 11a of the fixing nut 11 in the fixed state is In the surface side concave portion 16 of the moving blade b, it moves closer to the handle portion 7a and stops the development of the moving blade b.

  Next, when the moving blade 6 is moved in the direction of the stationary blade a so as to cut the hair, the head portion 11a of the fastening nut 11 slides on the surface-side recess 16 near the blade edge 12. During the sliding, both the blades a and b are closed. At the same time, the pin 18 slides in the groove 5 near the handle 7 of the stationary blade a.

  Therefore, the moving blade b becomes longer or shorter every time the deployment angle with respect to the stationary blade b is different, with the fixing nut 11 fitted in the long hole 8 of the moving blade b as a base point.

  That is, when the development angle of the moving blade b with respect to the stationary blade a increases, it looks longer, and when the development angle gradually decreases, the length decreases proportionally. Further, when the fastening nut 11 is slid into the elongated hole 8 near the blade edge 12a and the left side portion 14 of the surface side recess 16, the lengths of the stationary blade a and the moving blade b become the same, and both the blades a and b The blade edges 12 and 12a are configured to be aligned.

  Therefore, when the moving blade b cuts the hair, the pin 18 slides along the concave groove 5 when the developing angle is gradually narrowed from a state where the developing angle with the stationary blade a is widened and widened. The moving blade b is cut while the pin 18 slides and at the same time the moving blade b pulls the hair forward along the elongated hole 8 with the fixing nut 11 as a base point. This is the structural feature of the present invention.

  Accordingly, since the present invention cuts the hair as described above, resistance is not applied to the blades a and b, and the sharpness is very good.

  Further, since resistance is not applied to the blades a and b when the hair is cut, wear of the blade portions 12b and 12c of the blades a and b of the blades a and b is small. Therefore, there is an advantage that the number of times of polishing for the blade portions 12b and 12c can be reduced.
