Description

Technical Field

[0001] The present invention relates to hair cutting scissors, and particularly to electric hair cutting scissors.

Background Art

[0002] In the hair styling industry, hair styles vary according to fashion, and various hair styles are required according to individual preferences. Accordingly, hair cutting techniques have been improved, but the hair cutting scissors used here are manual scissors.

[0003] However, only manual scissors are used in the hair styling industry. In order to work with such manual scissors, the operation of cutting hair with manual scissors, that is, the operation of moving the moving blade with respect to the stationary blade, and the operation of designing a hair style must be carried out simultaneously. In particular, the operation of moving the moving blade with respect to the stationary blade requires moving the fingers for a long time, so the burden on the fingers is large. It can be said that this does not change much even with improved hair cutting scissors.

Mode for Carrying Out the Invention

[0009] Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. In the manicure scissors 1 according to an embodiment of the present invention, a moving blade 3 is swingably connected to a stationary blade 2 about a fulcrum shaft 4, and the moving blade 3 is moved by an electric mechanism 5. The electric mechanism 5 is housed in a housing 6, and the outer peripheral surface of the housing 6 serves as a gripping portion. The structure of the electric mechanism 5 is not particularly limited as long as it is a mechanism that allows the moving blade 3 to swing freely with respect to the stationary blade 2. The mechanism shown in the figure is an example, and the present invention is not limited thereto.

[0010] The base side of the stationary blade 2 is fixed to the housing 6. The base side of the moving blade 3 is a bent handle portion 7, and a slide groove 8 is formed in the longitudinal direction of the handle portion 7. The moving blade 3 is swingably connected to the stationary blade 2 via the fulcrum shaft 4. The rotating shaft of the motor 9 is connected to the rotor 12 fixed to the rotating shaft of the gear 11 via the gears 10 and 11. An engaging pin 13 is fixed to the tip of the rotor 12, and the engaging pin 13 is slidably engaged with the slide groove 8 of the handle portion of the moving blade. Thus, the engaging pin 13 of the rotor slides (reciprocates) while being engaged with the slide groove 8.

[0011] When the motor 9 is driven, the rotation of its rotating shaft is transmitted to the rotor 12 via the gears 10 and 11. Along with the rotation of the rotor 12, the engaging pin 13 at the tip of the rotor reciprocates (slides) along the slide groove 8 of the handle portion on the moving blade side, and accordingly, the moving blade 3 swings about the fulcrum shaft 4 (slider crank mechanism). Thus, similar to a normal manual scissors, the moving blade 3 swings about the fulcrum shaft 4 with respect to the stationary blade 2.

[0012] On the housing 6, switches 14 (14a, 14b) for controlling the movement of the electric mechanism 5 are provided at a plurality of locations on the outer peripheral surface that are spaced apart from each other, in the figure, at two locations on the upper and lower surfaces of the housing 6. The operation of the moving blade 3 can be controlled by operating the switch 14a or 14b at an easily operable location. Note that it is highly preferable for safety that the switch 14 (14a, 14b) is a momentary switch that is in the ON state only while the button is being pressed and becomes OFF when the button is released.

[0013] According to various cutting designs, the holding method is also changed in various ways to proceed with the cutting operation. At this time, by providing the switches 14a and 14b at a plurality of locations, the switch 14a or 14b that is easy to operate according to the holding method can be selected, so that the switch operation can be performed smoothly and the cutting operation can be carried out efficiently. If the holding method is fixed, it can be said that there is no need to provide the switch 14 at a plurality of locations. However, in hair dressing and beauty, even for manual scissors, there are various holding methods, and even for the electric hair dressing and beauty scissors 1, it is necessary to correspond to various holding methods. Therefore, providing the switch 14 at a plurality of locations has great significance.

[0014] A finger ring 15 through which a finger can pass is attached to the base end side of the housing 6 on the side opposite to the stationary blade 2 and the moving blade 3. This finger ring 15 is attached near the end on the base side of the housing 6 so as to suit the normal way of holding pliers. Passing a finger through this finger ring 15 can prevent dropping and enhance safety.

[0015] This finger ring 15 is preferably formed of an elastic body such as silicon or rubber. By forming it of an elastic body in this way, it is difficult to slip and the risk of dropping is avoided, enhancing safety. Also, since it stretches when pulled, it is easy to accommodate various ways of holding and the usability is improved.

[0016] As shown in FIG. 3, when using it in the normal way of holding where the moving blade 3 swings upward with respect to the stationary blade 2, and as shown in FIG. 5, in either case of the way of holding where the moving blade 3 swings downward with respect to the stationary blade 2, it can be easily held without twisting the wrist, and there is almost no burden on the wrist. On the contrary, in the conventional manual pliers 20, as shown in FIG. 8, from the state where the moving blade 21 swings upward with respect to the stationary blade 22, to make the moving blade 21 swing downward with respect to the stationary blade 22 as shown in FIG. 9, the wrist has to be twisted greatly, and the burden on the wrist is large.

[0017] In the normal way of holding, as shown in FIGS. 3 to 5, the housing (grip part) 6 is often held with the ring finger passed through the finger ring 15, but it can be used not only with the ring finger but also with other fingers passed through. For example, as shown in FIG. 6, it can also be used with the thumb passed through the finger ring 15. Also, as shown in FIG. 7, it can be used with the index finger passed through the finger ring 15. In this way, by appropriately changing the finger used according to the content of the cutting work, cutting work of various designs can be efficiently advanced.

[0018] The moving blade 3 is swung with respect to the stationary blade 2. At this time, the stationary blade 2 is supported by the housing 6 and does not move surely. On the other hand, with the conventional manual scissors 20, especially for beginners, it takes a considerable amount of concentration to work with the stationary blade 22 not moving surely. According to the hair and beauty scissors 1 of the present invention, such concentration is not necessary, so even beginners can easily operate it.

[0019] Note that in FIG. 1, the power supply of the electric mechanism 5 is shown as being connected from the power outlet to the main body of the electric scissors 1 via the AC adapter 16, but it can also be a cordless type with a built-in battery (rechargeable battery). Also, a speed controller (not shown) for controlling the swinging speed of the moving blade 3 can be provided.

[0020] According to the hair and beauty scissors 1 of the present invention, as described above, since the operation of moving the moving blade is automated, one can focus on the work of the cutting design, and the work efficiency can be greatly improved. Also, the burden on the fingers and wrists is significantly reduced compared to the conventional manual scissors 20, so the risk of tenosynovitis due to overusing the fingers can be greatly reduced.

Industrial Applicability

[0021] The hair and beauty scissors 1 according to the present invention can also be used as scissors for trimming pets.
