Description

[Detailed Description of the Invention] (1) Object of the Invention (a) Field of Industrial Application This invention relates to improvement of hairdressing shears.

(b) Prior Art Conventionally, hairdressing scissors of this type have a scissors body 2' having a cutting edge 1' and cutting blades 3', 3', as shown in Figures 5 to 10 of the attached drawings. During the closing operation with the scissor body 4', when the blade line of the cutting blade 1' and the base ends 6', 6' of each of the combing blades 3', 3' overlap and slide, the edges should be smooth. In order to achieve overlapping cross-sliding contact with the combing blades 3', 3', the back surface of each combing blade 3', 3' is partially or completely chamfered 8',
It is 8'.

(c) Problem to be solved by the invention In this case, on the back side of each of the combing blades 3', 3', there is a line extending from the base end 6', 6' of each combing blade 3', 3' toward the tip of each combing blade 3', 3'. The blade line 7' of each combing blade 3', 3' that existed before the chamfering 8' is removed or displaced by the chamfering 8'. Therefore, on the back side of each combing blade 3', 3', a gap is created between the blade line 3'', 3'' created by the chamfer 8' and the blade line of the opposing cutting blade 1', and the blade line 3 ``, 3'' and the cutting blade 1' lack the degree of overlapping, which reduces the scissors cutting rate.
At the blade base 3', at the point where the chamfered portion 8' on the back surface of each blade base end 6', 6' overlaps and intersects the cutting edge 1',
Hair is bitten into the gap created between the chamfered portion 8' and the cutting blade 1', and the cutting blade 1' and each combing blade 3', 3' open vertically, and the degree of overlapping between them increases. This has the disadvantage that hair cutting efficiency is significantly reduced.

(2) Structure of the Invention (a) Means for Solving the Problems This invention has been made by focusing on the above-mentioned conventional problems, and it provides a scissors body having a cutting blade 1 for hairdressing scissors. 2 and a scissor body 4 having comb blades 3 and 3 facing each other
Of these, protrusions 6, 6 are provided at the base ends of the respective combing blades 3, 3 provided on the scissors body 4 having the combing blades 3, 3, and on the back surfaces of the combing blades 6, 6, It is characterized by chamfering 8, 8 at an arbitrary angle on the tip of the protrusion 6, 6 or on the part up to the blade line 7 of each carding blade 3, 3. (b) Function Cutting blade 1 and the scissors body having combing blades 3, 3, the blade lines 7, 7 of each combing blade 3, 3 are entirely aligned with the blade of the opposing cutting blade 1. The cutting rate is good because the hair overlaps and comes into close contact with the wire without creating a gap, and when the hair is engaged with the base end of each combing blade 3, 3, the hair is attached to the blade of each combing blade 3, 3. The protrusions 6, 6 provided at the corners of the base end are used to cut the cutting blade 1 and each of the combing blades 3, 3 at the starting point of their overlap, and the protrusions 8, 8 and the cutting blade 1 are Because it doesn't get caught in the middle,
The cutting blade 1 and the combing blades 3, 3 overlap and come into close contact with each other without opening up and down, thereby improving the hair cutting efficiency.

(c) Example A scissors body 2 with a cutting edge 1 on one side edge and a scissors body 4 with combing blades 3, 3 on one side edge are arranged so that the cutting blade 1 and the combing blades 3, 3 are in close contact with each other. In the hairdressing scissors in which the scissors bodies 2 and 4 are pivotally mounted on a pivot shaft 5 while polymerizing, a protrusion is provided at the corner of the base end of each of the combing blades 3 and 3, respectively. 6, 6 are provided, and the back side of the protrusions 6, 6 is cut from the tip of the protrusions 6, 6 to the blade line 7, of each comb blade 3, 3.
The portions up to 7 are chamfered at arbitrary angles 8, 8.

(3) Effects of the invention As explained above, this invention has the following unique effects.

A protrusion is provided at the corner of the base end of each comb blade,
By simply chamfering the back side of the protrusion at an arbitrary angle from the tip of the protrusion to the blade line of each combing blade, the blade line of each combing blade is completely aligned with the blade of the opposing cutting blade. The cutting rate is good because the lines overlap closely without creating any gaps, and the protrusion provided at the base end of each combing blade allows the back edge line of the protrusion to be closely connected to the opposing cutting edge. In order to prevent hair from being bitten in between, the blade line of the cutting blade and the blade line of the combing blade are provided on each side edge with a scissor body having a cutting blade and a scissor body having a combing blade opposite to the scissors body. This is a significant invention that has the effect of significantly improving hair styling efficiency by allowing light opening and closing operations while closely connecting the two, and has the effect of being simple in structure, easy to manufacture and process, suitable for mass production, and easy to handle. It is.
