Description

[Detailed description of the device]

[0101]

[Technical field to which the device belongs]

 The present invention relates to hairdressing scissors used for barber beauty.

[0092]

[Prior art]

 Traditionally, hairdressing scissors have good sharpness when the hair is cut (that is, when the finger rests are opened) and the front and back blades are in close contact, and when the front and back blades are opened (that is, when the finger rests are closed). ) Was required to move lightly. However, it is extremely difficult to provide barber scissors having these two contradictory functions, and at the barber-cosmetic site, it is the fact that the barber-cosmetician's barber-cosmetic technology compensates for this defect. That is, when cutting, a force is applied in the direction of squeezing the thumb and the middle finger and three fingers against it, and when releasing, a force is applied to open the thumb and four fingers against it conversely, and the action is momentary. And rhythmically repeats. However, in the barber and beauty industry, when the above operation is repeated thousands of times a day (more than 10,000 times on a lot of days), those five fingers (further the muscles and nervous system from the finger to the upper arm) The burden on the patient is extremely large, causing chronic fatigue such as “stiff shoulders” and “octopus”, and the load over many years has also been a cause of occupational diseases unique to barber and beautician such as tendonitis. Although various technical improvements have been tried to solve these problems, they have not been put to practical use. For example, some bearings are provided on the contact surfaces of the front and back blades near the connecting tool to reduce the mobility when opening and closing. However, the improvement plan is lighter when it is movable, but on the contrary when it is cut, the adhesion becomes poor, and it is necessary to apply extra pressure to the fingertip (it is necessary to squeeze the finger hook part). Not used critically.

[0093]

[Problems to be solved by the device]

 The present invention eliminates these drawbacks and provides hairdressing scissors that adhere well to the front and back blades when cutting hair, have excellent mobility when the hair is open, and do not put extra load on the five fingers. It was made.

[004]

[Means for Solving the Problems]

 According to the present invention, a through hole is provided at a position slightly closer to the handle part than the connecting tool of the front blade portion, and after inserting the back indenter into the through hole, the front and back blades are passed through the back indenter by the pressing means installed on the front blade. The scissors for hairdressing and beauty are characterized in that a separating force can be applied so that they separate from each other. More specifically, the pressing means installed on the front blade is a leaf spring, and one end of the leaf spring is fixed near the through hole of the front blade, and the other end of the leaf spring comes into contact with the back pressure element to apply pressure. Alternatively, the pressing means installed on the front blade is a spiral spring, and the separating force of the spiral spring is contacted so that it can be transmitted to the back blade through the back pressure element. The hairdressing and scissors are configured to cover the spring and the back pressure element with a stator and pivotally attached to the front blade (Claim 3).

[0095]

[Embodiment of device]

 Since the present invention has the above-described structure, when using it, like the ordinary scissors for hairdressing, attach the thumb and the other four fingers to the finger hooks respectively, and open and close for cutting. Repeat the operation. However, when trying to close both blades when cutting the hair, the back indenter provided on the front blade is pressed by the pressing means and slightly comes out from the through hole, so the separating force is transmitted and the back blade is pushed. This is nothing but enhancement of the adhesion between the facing cutting edges of the front and back blades. Therefore, the user can close the scissors and cut the hair without applying extra adjustment force to the five fingers or the wrist. Also, when opening both blades, it is possible to move the thumb and other four fingers lightly, just as in the conventional case.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. The first embodiment of the present invention is shown in FIG. 2 which is an assembly view of the main part thereof and FIG. 3 is a side sectional view of the main part thereof. As shown in the above figure, a through hole 4 is provided at a position slightly closer to the finger rest than the connecting tool 3 of the front blade portion 1, the back pressure element 5 is inserted into the through hole 4, and then the pressure applied to the front blade The scissors for hairdressing and cosmetics are configured so that a separating force can be applied to the front and back blades by means of the step 6 through the back indenter. The pressing means 6 installed on the front blade 1 is a leaf spring A, one end of the leaf spring A is fixed to the vicinity of the through hole of the front blade by a pivoting screw 7, and the other end of the leaf blade A is a spine. It is configured to contact the indenter 5 to apply pressure. Next, a second embodiment of the present invention is shown in FIG. 4 which is an assembly drawing of the main part thereof and FIG. 5 is a side sectional view of the main part thereof. In the second embodiment, as shown in the above figure, the back pressure element 5 has a ball shape, one end of the leaf spring is fixed to the vicinity of the through hole by the welded portion 8, and the other end of the leaf spring A contacts the back pressure element 5. It is configured to pressurize. FIG. 6 is an assembly view of the essential parts of the third embodiment of the present invention, and FIG. 7 is a side sectional view of the essential parts thereof. In the third embodiment, as shown in the above figure, the pressing means 6 installed on the front blade 1 is the spiral spring B, and the separating force of the spiral spring B is contacted so that it can be transmitted to the back blade through the back pressure element 5. Further, the hollow concave stator 8 covers the spring B and the back pressure element 5 and is pivotally attached to the front blade. The back pressure element 5 of the present invention has a length slightly thicker than that of the front blade as in the above-described embodiment, and the shape thereof is formed into a rod shape or a spherical shape. Further, the leaf spring is preferably made of a repeatable material such as a hard material, and as in the above-mentioned embodiment, one end thereof is fixed to the front blade by means of pivotal attachment or welding, adhesion, fitting, etc. To be done.

[Effect of device]

 Since the present invention has such a configuration, the following excellent effects are exhibited. Equipped with a self-pressurizing means such as a leaf spring or a spiral screw, it is possible to apply a reciprocal force to the front and back blades. Therefore, the adhesion of the cutting blade crossing surface required for hair cutting is extremely good, and the fine adjustment of the hand and wrist that a hairdresser does as a hairdressing and beauty technique is unnecessary. Especially for hair cutting on the far side / downward side where the line of sight is hard to reach, even a skilled hairdresser was struggling to adjust the five fingers, but with the scissors of the present invention, the adjustment of the fingertips is almost unnecessary. In addition, the work can be done very easily. In addition, the load on the five fingers and wrists will be reduced, and chronic symptoms such as stiff shoulders and octopus, and occupational diseases peculiar to hairdressers such as tendonitis will be relieved. When opening the scissors, there is no discomfort with conventional products, and it has the advantage that it can be used naturally.
