Description

[Detailed description of the invention] [Technical field] This invention relates to an electric hair clipper in which a head case equipped with a fixed blade and a movable blade is pivotally connected to a grip case so as to be swingable. The purpose is to facilitate the swinging operation of the head case.

[Background technology]

Regarding this type of electric hair clipper with a swinging head,
This has already been proposed by the applicant, as shown in FIGS. 2 and 3, the fixed blade 2
A head case 1b equipped with a movable blade 3 that slides on the upper surface of the head case 1b is pivotally connected to the grip case 1a so as to be swingable around a support shaft 4, and a fixed blade 2
The angle between the grip and the case 1a can be variably adjusted.
In particular, the neckline can be easily trimmed with a comfortable grip.

However, the problem with this is that head case 1
(b) Holding it directly in your hand and operating it by swinging it. During or after use, a lot of hair particles adhere to the top of the head case 1b, so when you grip the head case 1b when swinging the head, the hair particles stick to your hands, which not only makes you feel uncomfortable. , the hand slipped, making it difficult to swing the head case 1b.

[Purpose of invention]

This idea was made in order to solve this problem.The operating knob that can swing the head case is attached to the grip case, which does not have hair particles attached to it. This allows the head case to be swung easily and reliably without causing any trouble. Examples thereof will be described below based on the drawings.

[First Embodiment] Figures 1 to 3 show an embodiment of an electric hair clipper according to this invention, in which a main body case 1 has a long box-shaped grip case 1a that is long in the front and back direction.
and a head case 1b provided with a fixed blade 2 and a movable blade 3, and the head case 1b is pivotally attached to the grip case 1a so as to be swingable around a support shaft 4. Specifically, the grip case 1a and the head case 1b have two positions: a basic position where the head case 1b is in a substantially straight line in front of the grip case 1a (see the virtual line state in FIG. 3), and an upwardly tilted position. (See the solid line state in the same figure) It is pivotally connected to the left and right support shafts 4, 4 so that it can swing freely.

In FIG. 2, a motor 5, a battery 6, etc., which are the power source of the movable blade drive mechanism, are built into the grip case 1a. A blade unit 7 having a fixed blade 2 and a movable blade 3 is removably assembled on the lower surface side of the head case 1b. The blade unit 7 includes a comb-shaped fixed blade 2 inside a unit base 8 having a U-shaped cross section.
The movable blade 3, also in the shape of a comb, is pressed against the upper surface of the fixed blade 2 by a spring 10 attached to the unit base 8. A vibrator 1 is installed inside the head case 1b.
1, and a vibration lever 12 integrally formed at the front end of the vibrator 11 is made to protrude forward to move the movable blade 3.
It removably engages with a passive piece 13 fixed to the upper surface side. Further, an eccentric pin 15 fixed on the shaft of the motor 5 is engaged with a vertically long groove 14 formed on the rear end surface of the vibrator 11. In such a case, the vibrator 11 is moved to the eccentric pin 15 by driving the motor 5.
When the movable blade 3 is vibrated back and forth in the same direction, the vibration lever 12 integrated with this vibrates back and forth in the same direction.
slides back and forth on the upper surface of the fixed blade 2 in the left-right direction. For example, when cutting the nape of the neck, head case 1b
However, due to this upward attitude, the angle α of the fixed blade 2 with respect to the upper surface of the grip case 1a becomes smaller than when the head case 1b is in the straight basic position, so the grip case The nape of the neck can be trimmed in an easy-to-grip posture at a substantially right angle without having to lie the device 1a vertically relative to the head.

In the electric clipper having such a structure, the present invention is characterized in that the operation knob 16 for swinging and rotating the head case 1b is mounted on the outer surface of the grip case 1a rearward of the support shaft 4. That is,
In the illustrated example, the support shaft 4 of the grip case 1a is
The operation knob 16 is mounted on the lateral outer surface of the rear side so as to be slidable in the front and back direction, while the head case 1b
An elongated hole 17 is formed in the radial direction of the shaft in a portion offset from the center on the inner end surface of the support shaft 4 protruding from the inner surface of the main body case, and the base end of the link 18 installed inside the main body case is connected to the operation knob 16 with the screw 19. At the same time, a pin 20 protruding from the tip of the link 18 is engaged with the elongated hole 17. A means for positioning the operating knob 16 is provided between the operating knob 16 and the grip case 1a. Specifically, an engaging element 21 is provided on the operation knob 16 side via a spring 22 so as to be freely retractable, and recessed portions 2 are provided on the grip part case 1a side at two positions, front and rear.
By selectively engaging one of the engaging elements 3 and 24 with the engaging element 21, the operating knob 16 is held switchably between two positions A and B, front and rear.

When the operation knob 16 is stopped at the rear position B as shown in FIG. When it is slid forward from B, the head case 1 is moved through the link 18.
b rotates upward around the support shaft 4, and the operation knob 16
When the head case 1b stops at the front position A, the head case 1b is tilted upward at a desired angle. On the other hand, when the operation knob 16 is slid backward from the front position A to the rear position B, the head case 1b returns to its original basic position of approximately a straight line.

[Second Embodiment] In the first embodiment, the head case 1b swings and rotates via the link 18 by sliding the operation knob 16.
The head case 1b may be oscillated via the parallel links 25 and 26 by rotating the operation knob 16 as shown in FIGS. Specifically, the operation knob 16 is rotatably fitted into a circular opening 27 opened on the lateral outer surface of the grip case 1a, and the operation knob 16 and the inner end surface of the support shaft 4 of the head case 1b are connected to each other. The parts are connected by mutually parallel links 25 and 26. When it comes to scolding, now.
As shown in FIG. 4, when the operation knob 16 is rotated by a predetermined angle β in the direction C under the basic posture in which the head case 1b is in the aforementioned substantially straight line, the head case 1b
b rotates around the support shaft 4 through the parallel movement of the parallel links 25 and 26, and assumes an upwardly inclined position as shown in FIG.

In addition, in any embodiment, the head case 1
b can be made to be able to swing in two or more steps from the basic posture of being in a substantially straight line.

In addition, by operating the operation knob 16, the head case 1
The specific means for swinging the operating knob 16 may be other than the link mechanism described above. For example, the operating knob 16 and the head case 1b are transmitted by a rack and pinion, and the operating knob 16 is rotated. Then, the head case 1b may swing around the support shaft 4 via these rack and pinions.

[Effect of idea]

As explained above, according to this invention, the operation knob 16 for swinging the head case 1b
is positioned on the outer surface of the grip case 1a rearward from the support shaft 4, and hair debris is rarely attached to the outer surface of the grip case 1a.
Using the operating knob 16, the head case 1b can be swung comfortably, simply and reliably, and is easy to use.
