Description

[Detailed explanation of the invention] [Industrial application field] This invention is used for hairdressing (barbering) and hairdressing (cosmetology).
This invention relates to electric hair cutters used for hair clippers, etc.

[Conventional technology]

Conventionally, hairdressing and beauty hair, etc. have been used for example,
Manual scissors as shown in the figure are used.

[The problem that the idea attempts to solve]

However, many barbers and hairdressers complain of hand fatigue and stiff shoulders when using manual scissors because they work long hours at barber and beauty parlors, for example, and if they continue to work for many years, they can develop tendinitis in their wrists. There is also fear.

Therefore, there has been a demand for an electric tool to replace the manual scissors.

By the way, electric hair clippers are sometimes used in hairdressing, but the styles that can be cut with electric hair clippers are very limited, such as round cuts, square cuts, and close-cropped hair, and require a variety of cutting methods and hairstyles. Hairdressing/
It cannot be used in place of manual scissors for hairdressing.

Therefore, the main purpose of this invention is to provide an electric tool that can be used at least in a similar manner to manual scissors.

[Means to solve the problem]

The electric hair cutter according to this invention includes a body, a connecting part coaxially rotatably attached to the front part of the body, and one end of the connecting part extending along the axis of the body and the body. A fixed elongated stationary blade having a large number of incisors along one long side, and an elongated and removable movable blade superimposed on the stationary blade so as to be able to reciprocate and move freely along one long side. a movable blade that has a large number of incisors along the body and cooperates with the static blade; an electric driving means that is housed in at least one of the body and the connecting part and reciprocates the movable blade; and a handle having a finger hole for passing a finger through the handle.

[Effect]

When the driving means is operated, the movable blade reciprocates on the stationary blade, and hair can be cut by the cooperation of the two blades.

What's more, this electric hair cutter has an elongated static blade and a movable blade that extend forward from the body via a connecting part, and a handle with finger holes attached to the rear, making it similar to manual scissors as a whole. Because of this, it can be used similar to manual scissors.

〔Example〕

FIG. 1 is a front view showing an electric hair cutter according to an embodiment of the invention with its moving blades disassembled. FIG. 2 is an enlarged view of the blade portion of FIG. 1 viewed in the direction of arrow P.

Simply put, this electric hair cutter consists of a body part 14, a connecting part 12, a static blade 2, a moving blade 4, and a handle part 22.
and a driving means 24, etc., and the overall shape is similar to manual scissors as shown in FIG. 4, for example.

To be more specific, the trunk 14 has a cylindrical shape, and the connecting part 12, which also has a cylindrical shape, is attached to the front part of the trunk 14.
The body 14 as shown by arrow B centering on the axis 15 of 4.
are rotatably fitted coaxially.

It is most convenient to use the rotatable angle of the connecting portion 12 at 360 degrees, but it may of course be limited to a smaller angle.

However, it is preferable that the connecting part 12 can be rotated only when desired by the user (for example, a hairdresser or beautician; the same applies hereinafter), and cannot be easily rotated at other times. To do this, for example, the fitting part 13 between the connecting part 12 and the body part 14 is provided with several protrusions on one side and recesses at required angles on the other side, so that the fit between the two can be improved. Therefore, the connecting portion 12 may be rotated by a required angle only when force is applied, or instead of doing so, a screw 16 may be provided in the body portion 14, After the connecting portion 12 is rotated in a desired direction, the fitting portion 13 may be tightened to fix the connecting portion 12.

One end of the elongated stationary blade 2 is fixed to this connecting part 12 in such a way that it extends forwardly therefrom, ie along the axis 15 of it and the body part 14 . This stationary blade 2 has a large number of cutting teeth 2a along one long side thereof. Therefore, the structure is completely different from conventional electric clippers.

In addition, this stationary blade 2 has a long and thin movable blade 4 having a large number of incisors 4a along one long side, which is disassembled in FIG. 1, but as shown in FIG. slides) can be stacked freely.

More specifically, the stationary blade 2 is provided with a protrusion 2b along the long side opposite to the incisor 2a,
A presser plate 6 is placed on top of it and several screws 10 are placed on top of it.
This creates a gap 8 between the stationary blade 2 and the holding plate 6 corresponding to the thickness of the moving blade 4.
The cutting teeth 4a of the moving blade 4 are formed in this gap 8.
The opposite side is sandwiched to prevent it from lifting up while guiding the reciprocating movement as shown by arrow A.

Therefore, the movable blade 4 is provided with a screw at a position corresponding to the screw 10 in order to insert the movable blade 4 into the gap 8 so as not to interfere with the screw 10, and to guide the sliding of the movable blade 4 in the inserted state. A notch 4b is provided.

Further, at the rear end of the moving blade 4, an elongated hole 4 is provided for inserting an eccentric pin 30a of a bevel gear 30, which will be described later.
With this structure, the movable blade 4 is removable, that is, replaceable. The method of exchange will be described later.

The holding plate 6 may be made of metal, or may be made of resin such as Teflon from the viewpoint of reducing friction. The pressing pressure can be adjusted using the screw 10, and thereby the strength of contact between the movable blade 4, the static blade 2, and the presser plate 6 can be adjusted. However, the protrusion 2b may be provided on the holding plate 6 side, or the holding plate 6 may be integrated with the stationary blade 2.

Also, in this example, the number of incisors 4a of the moving blade 4 is greater than the number of incisors 2a of the stationary blade 2 to prevent a large amount of hair from entering both incisors 2a and 4a at once. , the load on the motor 26, which will be described later, is lightened.

In addition, in this example, both incisors 2a and 4a are sharpened towards the joint between them, as shown in FIG. 2, so that the shape resembles the cutting edge of manual scissors. . Furthermore, as shown in FIG. 2, the tip of the incisor 4a of the movable blade 4 is slightly retracted from the incisor 2a of the stationary blade 2 to prevent injury to people.

On the other hand, in this example, an electric driving means 24 for reciprocating the movable blade 4 is housed inside the body section 14 and the connecting section 12.

An example of this driving means 24 will be explained with reference to FIG. 3. A motor 26 is housed in the body 14, and a bevel gear 28 is attached to the rotating shaft of the motor 26.
and a bevel gear 30 rotatably housed within the connecting portion 12 are meshed within the connecting portion 12.

On the opposite side of the bevel gear 30 from the teeth, an eccentric pin 30a eccentric from the center of rotation is erected, and this is inserted into the elongated hole 4c of the moving blade 4 described above.

Therefore, when the motor 26 is rotated and the bevel gear 30 is rotated, for example, as shown by arrow C, the eccentric pin 30a and the elongated hole 4c of the moving blade 4 cooperate to
The movable blade 4 reciprocates as shown by arrow A.

The motor 26 is turned on and off by operating the switch 20 provided at the bottom of the body 14 with the thumb. For example, the switch 20 has an end portion 20a.
When you press the side, it turns on only while you press it, and the end 2
A switch that turns on continuously when the 0b side is pressed and turns off when pressed again is convenient and safe to use, but of course other switches may also be used.

Note that various types of electric drive means 24 can be used in addition to the above-mentioned configuration. For example, the eccentric pin 30a of the bevel gear 30 and the moving blade 4 may be connected using a crank, or the moving blade 4 may be directly reciprocated using a piston type motor or vibrator instead of the rotary motor 26. It may be something that makes you do something.

Further, as the power supply system for driving the motor 26, various systems such as an AC 100V power supply, a DC power supply using an external adapter, and a rechargeable battery can be used depending on the system and purpose of the driving means 24. In the case of a battery-powered device, the body portion 14 may be appropriately enlarged and housed therein.

Furthermore, a handle part 22 is attached to the rear part of the body part 14, and has a shape similar to the handle of manual scissors and has a finger hole 22a through which a finger (ring finger) is passed.

The handle portion 22 may be fixed to the body portion 14, but it is preferable that the handle portion 22 can be bent up and down within a predetermined angle as shown by arrow D as in this embodiment. In that case, similarly to the case of the connecting part 12, the handle part 22 may also be bent in a moderation manner at a predetermined angle, or may be bent continuously, but in any case, here Since a relatively large force is applied to the screw 18,
It is preferable to fix it with

To show an example of cutting hair using this electric hair cutter, the ring finger of one hand of the user is passed through the finger hole 22a, and the hair is cut from the handle 22 to the body 14, similar to holding manual scissors. Hold this electric hair cutter in the desired direction by grasping the loose end. Then, with your thumb turning on the switch 20 and reciprocating the movable blade 4, just lightly apply the incisors 2a and 4a of both blades 2 and 4 to the part of the hair that you want to cut, and the blade will automatically cut. hair is cut. In that case, you may attach a comb held in the other hand as needed, just as when using manual scissors.

Therefore, unlike manual scissors, this electric hair cutter allows you to cut hair very easily and continuously and efficiently, increasing work efficiency and reducing hand fatigue even after long hours of work. There is no risk of developing tendinitis in the wrists even if you continue working for many years.

Moreover, this electric hair clipper is completely different from conventional electric hair clippers, and has an elongated stationary blade 2 and moving blade 4, and a handle 22 with finger holes 22a, and has a shape similar to manual scissors as a whole. Ori,
It can be used similar to manual scissors. That is,
You can create free cuts and hairstyles such as straight lines and curves.

On the contrary, since the movement of the moving blade 4 is finer and continuous than with manual scissors, it is possible to cut straight lines, curves, etc. more freely and continuously in three dimensions than with manual scissors. Therefore, it is possible to create a variety of free hairstyles not only for hairdressing but also for beautiful hair with great fashionability.

Of course, you can also use it like a conventional electric clipper to perform round, square, and cropping operations.
In that case, unlike conventional electric clippers, the length of hair left on the head can be freely adjusted by changing the angles of the static blade 2 and the movable blade 4 with respect to the surface of the head.

In addition, in this electric hair cutter, the connecting part 1
By rotating 2 in the direction of arrow B, the orientation of the incisors 2a and 4a can be freely changed not only upward as in the illustrated example but also in other directions. The direction of approach can be freely changed. Therefore, hair can be cut more easily, freely, delicately, and accurately without forcing the user's arms, wrists, etc. to take an unreasonable posture.

Furthermore, in this embodiment, the handle 22 can be bent in the direction of arrow D, so that the relationship between the user's wrist and the direction in which the double blades 2 and 4 extend can be adjusted to suit the user. You can choose the one that suits you best. Therefore, from this point of view as well, hair can be cut more easily and freely.

In addition, since the moving blade 4 of this electric hair cutter is removable, even if the cutting quality deteriorates due to long-term use, it is not necessary to repair the entire electric hair cutter (unlike manual scissors). ), there is no need to send the moving blade 4 to the user, etc.
can be easily replaced. Therefore, the interval between repairs can be extended, and one electric hair cutter can be used efficiently.

Note that when replacing the moving blade 4, it is not necessarily necessary to remove the holding plate 6; for example, if necessary, the screw 10 may be slightly loosened, the cover of the connecting portion 12 may be removed, and the moving blade 4 may be shifted as much as possible. In this state, the connection between the elongated hole 4c and the eccentric pin 30a of the bevel gear 30 is removed, and the movable blade 4 is taken out from the gap 8.
Furthermore, if the sharpness does not recover much even after replacing the movable blade 4, you can send it in for repair and replace the stationary blade 2 as well.

[Effect of idea]

As mentioned above, the electric hair clipper of this invention has a movable blade that moves back and forth with respect to a static blade, but unlike conventional electric hair clippers, it has an elongated static blade, a moving blade, and a finger hole. The overall shape is similar to that of manual scissors, such as having a handle, and it can be used similar to manual scissors.

What's more, it allows you to freely and continuously cut straight lines and curved lines, so it is as effective as or better than manual shears.
You can freely cut your hair and create your own hairstyle. Of course, you can also use it in the same way as a conventional electric clipper.

What's more, since it's electric, you can cut hair very easily and efficiently, increasing your work efficiency, and even if you work for long hours, you won't get tired hands or stiff shoulders, and you can work for many years. Even if you continue using it, there is no risk of developing tendinitis in your wrist.

In addition, the connecting part is rotatable so that the orientation of the incisors of the static and moving blades can be freely changed, making it easier to use without forcing the user's arms or wrists into uncomfortable positions. Hair can be cut freely and accurately.

In addition, since the moving blade is detachable and replaceable, the sharpness can be easily restored by replacing the moving blade, thereby extending the repair interval for the entire electric hair cutter. Therefore, one unit can be used efficiently.
