Description

  The present invention relates to a hairdressing scissor used in a barber or beauty salon.

  As shown in FIG. 1, a hairdressing scissor generally has a configuration in which blade bodies 3 and 4 having finger ring portions 1 and 2 are pivotally attached to a flat portion 5 and 6 of a base by a pivot 7. .

  When cutting hair or the like using a hairdressing scissor, it is necessary to prevent the blade from being lifted by the hair being sandwiched between the blades in order to increase the shearing force and improve the sharpness. Therefore, when cutting hair or the like, the blades of both blades are pressed while causing one blade to bend around the pivot by a fingertip operation inserted into the finger ring.

Further, in the following Patent Document 1, a leaf spring body having a cross shape is interposed between a tightening nut screwed to a pivot and a blade body, and a lower protrusion is formed on the tip and one arm of the leaf spring body to form a blade. There has been disclosed a hairdressing scissor that holds the body and prevents the blade body from floating when cutting hair or the like.
JP-A-9-285656

  There are right-handed and left-handed scissors for barbers, and right-handed barbers and beauticians hold a left-handed barber in the right hand, as with right-handed barbers. When the opening / closing operation is performed so that the body is curled, the blade edges come to float apart from each other, and the sharpness is extremely lowered, or the hair or the like cannot be cut at all. The same applies when a left-handed barber or beautician opens and closes with a right-handed barber in his left hand.

  Regarding the method of cutting the hair, there is a method called so-called “straightening” in which the hair is cut along the head while opening and closing the ridges without using a comb. Of this thumb, of the thumb and ring finger inserted into the finger ring, there is a push-and-push to move the thumb and a pull-and-push to move the thumb. The same problem as the above, in which, as with the straight blade, if one of the blades is bent and the straight blade is pulled, the blade edges become separated and floated apart, and the sharpness is extremely reduced. Arise. The same problem arises when a barber or beautician who regularly conducts direct pulling performs push directing as well as pulling direct punching.

  The problem as described above cannot be solved even in a hairdressing scissor provided with a leaf spring body in which a lower protrusion is formed on the tip and one arm, as disclosed in Patent Document 1 above. When opening and closing operation so that one blade body is bent only by holding one side of the pivot, the other side floats and the blade edge is separated, and the leaf spring body is elastically deformed and the blade edge is the same This is because they come apart.

  The present invention solves the above-mentioned problems and does not impair the sharpness of a barber or beautician, whether right-handed or left-handed, even when performing push-toe or pull-toe. The object is to provide a hairdressing salon.

The invention according to claim 1

According to the first aspect of the invention, the first blade body is pressed against the second blade body side by the protrusion on the blade body distal end side, and the contact pressure between the blade bodies increases, and the meshing force of the blades Will increase. Also, right-handed barbers and beauticians can use left-handed barbers because the flat part of the first blade is pressed against the flat part of the second blade in close contact with the flat part by the protrusions on both sides of the pivot. Even if it is operated like a right-handed hairdressing scissors using a scissors, the blades of both blades can be prevented from rising, or the lifting can be reduced, cutting hair etc. without impairing sharpness it is possible to carry out the operation, that the barber or hairdresser left-handed is the same when carried out using the hairdressing scissors for right-handed, also a straight scissors pull the barber or hairdresser to do a straight scissors press daily When performing, or conversely, when a barber or beautician who performs straightening, the straightening of the hair or the like can be performed without impairing the sharpness. Further, by locking or fastening the tail end on the finger ring part side to the first blade body to prevent the rotation, the above-described effects can be surely produced without the washer being rotated even if the tightening nut is tightened. it can.

  FIG. 2 is a diagram for hairdressing in which the flat portions 13 and 14 formed with the first blade body 11 and the second blade body 12 at the base portion are pivotally attached by the pivot 15 with the flat portions in contact with each other. This shows the base structure of the scissors. The pivot 15 has a lower end threaded portion 15 a screwed into the second blade body 12, and is pivotally supported by the first blade body 11 via a bearing 16. . A washer 17 is fitted on the pivot 15 protruding from the first blade body 11, and a tightening nut 18 is screwed into the threaded portion 15b of the protruding portion.

  The washer 17 is made of high-rigidity steel, and as shown in FIG. 3, protrusions 21 and 22 are formed on both sides of the fitting insertion hole 19 that passes through the pivot shaft 15 and on the tip end side of the blade body. A locking portion 24 that fits and locks into a recess 23 formed in the first blade 11 is formed at the tail end.

The hairdressing scissors of the present embodiment are configured as described above, and when the washer 17 is fitted on the pivot 15 and the locking portion 24 at the tail end is fitted and locked into the recess 23 of the first blade body 11, The washer 15
1268033633187_0
The tightening nut 18 screwed into the pivot 15 is in point contact with the washer 17 at point a by inclining so that the tip end side is high and the tail end side is low. A force F is applied to the washer 17 at point a by tightening the tightening nut 18. When the distances from the contact portion b between the protrusion 21 and the first blade body 11 to the point a and the protrusion 22 are 1 and r, respectively, the protrusion 22 causes the first blade body 11 to have R = l / r · The force F is applied, whereby the first blade body 11 is pressed against the second blade body on the tip side, increasing the contact pressure between the blade bodies and increasing the meshing force of the blades.

  Also, by the force F applied to the washer 15, the projections 22 on both sides of the pivot also press the first blade body 11 on both sides of the pivot to increase the contact pressure between the flat portions. As a result, the blade body 11 does not tilt in any direction, so that the blades are not engaged with each other and the blade is not lifted. In other words, even if a right-handed person holds a left-handed heel in his right hand and tries to operate the blade 11 like a right-handed heel, the blade will not rise and impair the sharpness. When a left-handed person holds a right-handed heel in his left hand and operates in the same way as a left-handed heel, the sharpness is not impaired.

  In addition, the sharpness is not deteriorated in the same manner when performing the pushing and punching.

  The present invention is applied to barbers for hairdressing used by barbers and hairdressers.
