By the way, the cutting style has recently become popular.
After ~ 2 weeks, the hair grows and the hair on the sides above the ears becomes uneven and needs to be cut. At this time, if you use the above-mentioned conventional hair cutter, you have to cut the comb diagonally according to the style and cut,
It can't be done alone, and an amateur can't finish it well.

For this reason, in Japanese Utility Model Laid-Open No. 52-36569, the line connecting the tips of the cutting guide members arranged on one side of the comb-shaped blade has a required angle with respect to the tip edge of the blade. Then, by cutting with the tip of the cutting guide member in contact with the head, it is possible to perform cutting at the required angle.

However, since the cutting guide member exists only on one side of the blade and the contact member also exists only on one side of the blade, it is only necessary to reverse the direction of moving the hair cutter on the left and right sides of the head. The cutting guide member comes into contact with the hair first and the blade comes into contact with the hair prior to the cutting guide member, so that the same finished cut cannot be obtained. If the hair cutter is moved so that the cutting guide member comes into contact with the hair before the blades on the left and right sides, the cutting guide will be placed so that the angle formed by the line connecting the tip of the cutting guide member and the tip edge of the blade is opposite. The orientation or setting of the member relative to the blade must be changed.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a hair cutter capable of easily and cleanly trimming hair in a trimming style.

[0007]

On the other hand, the slide body 31 and each bar 33 slide in the axial direction of the tubular body 30.

Then, the cutting guide member 3 is attached to the main body 1
By covering the outer surface of the tip end of the blade and operating the adjusting knob 35 of the cutting guide member 3, an angle α formed by the line connecting the tips of the skin-contacting members composed of a plurality of bars 33 and the tip edge of the blade 2 is set. According to the cutting angle, as shown in FIGS. 8 and 9, the tips of the bars 33 arranged on both sides of the blade 2 are brought into contact with the scalp, and in this state, as shown by the arrow in FIG. If the hair cutter is moved in a direction orthogonal to the tip edge of the blade 2, a cut suitable for the required mowing angle is made, and the angle α at this time operates the adjusting knob 35 as described above. By doing so, it is possible to adjust in multiple stages according to the cutting angle.

The same applies to the case of cutting on the opposite side of the head, but the bars 33 located on both sides of the blade 2 are shown in FIG.
As shown in (a), since the hair cutter is located at the same distance from the blade 2, the hair cutter moves in the opposite direction when cutting, but the same cutting method can be used, and if the left and right sides are uneven, It never happens. Even if the angle α is changed during the left and right cuts, the adjustment knob 3
It is possible to easily return to the previous state from the display by 5 and the display unit 80.

Then, by operating the operation handle 37 to slide the slide body 31 and each bar 33 as a whole with respect to the cylinder body 30 and the cover 32 as shown in FIG.
As shown in FIG. 11, the cut can be performed according to the length L of the shortest part of the hair. The hair that has been cut and entered the inside of the cutting guide member 3 from between the bars 33 is
It passes through between the slide body 31 and the cylinder body 30 and between the slide body 31 and the cover 32, and is discharged from an opening 62 provided in the cylinder body 30.

Here, the bars 3 lined up on both sides of the blade 2
3, the distance between the bars 33 on the side with a short protruding length (A in FIG. 2) is the distance between the bars 33 on the side with a long protruding length (see FIG. 2).
It is smaller than B) in the middle and the bar 3 in the middle part
It is preferable that the interval of 3 is set to an intermediate value between the above two intervals in terms of hair raising and introduction efficiency. For example, A is 7 to 9 mm and B is 15 to 16 mm.
This means that the side with the short protruding length is closer to the ear and cuts short hair, but if the interval between the bars 33 in this portion is wide, the effect of raising the short hair is lost and the portion with the long protruding length is cut off. This is because if the interval is shortened, long hair is often pushed down.

Also, when the protruding length of each bar 33 is set to be the shortest so that the line connecting the tips of the bars 33 is parallel to the tip edge of the blade 2, as shown in FIG. Also, the tip of each bar 33 is projected. The cutting guide member 3 prevents damage to the blade 2 when the product is transported.
That is why it is possible to prevent it. When cutting the burned-up portion, the cutting guide member 3 may be removed and the blade 2 may be applied as shown in FIG. This time,
If the total length W of the blade 2 is set to about 70 mm, it is possible to sharply shave the straight line of the raised portion. Further, if the length W is set as described above, the cutting according to the above-mentioned cutting angle can be performed at once, and a sparse pattern or a striped pattern unlike the case where the cutting is performed a plurality of times does not occur. . In addition, the total length W and the above-mentioned pitch A,
From the relationship of B, in the illustrated example, the six bars 33 are arranged side by side, but the number is not limited to this.

When the blade 2 having such a total length W is used, the main body 1 tends to have a large horizontal width, and when the horizontal width of the main body 1 increases, the width of the cutting guide member 3 to be covered with the main body 1 also increases. It becomes easier to hit the ears and smooth cuts cannot be made. If the side edge of the blade 2 is made to protrude beyond the side surface of the main body 1, the width of the main body 1 will not be a problem, but it will give the user a dangerous feeling, or the side edge of the blade 2 will be different. It often causes damage when applied. For this reason, FIG.
As shown in FIG.
Since 0 and 90 are provided and the side end of the blade 2 is housed in the notch 90, the width of the main body 1 is smaller than the total length W of the blade 2, and the width of the cutting guide member 3 is also smaller. At the same time, the hair can be made small, and as shown in FIG. 13 (b), the hair can be cut short, and the blade 2 is not damaged.

In the embodiment shown in FIG. 14, the main body 1 is constructed by adding a pruning board 9 having a comb-teeth-shaped tip covering the blade 2.
The figure shows a single cut that can be made by pruning.

In the embodiment shown in FIG. 15, the adjusting knobs 35 are arranged on both sides. Of the two adjusting knobs 35 that are engaged with both ends of the lever 34, the inclination angle of the line connecting the tips of the bars 33 is reversed when one of them is slid forward and the other is slid forward.
If the above inclination is reversed when the left side of the hair is cut and the right side is cut, the positional relationship between the fixed blade 20 and the movable blade 21 in the blade 2 is made the same with respect to the direction in which the hair cutter is moved. As a result, it is possible to more strictly equalize the left and right cut finishes.

In the first embodiment, the adjusting knob 35 is arranged on the side surface of the body 1 on the side where the plug cover 16 is located to enhance the design of the device and to make it compact. As shown in 16, it may be arranged on the surface of the cutting guide member 3 as a dial. In this case, the adjusting knob 35 is sandwiched on both sides of the lever 34 by a pair of protrusions (not shown) protruding from the back surface thereof, and as the adjusting knob 35 rotates, the pair of levers 34, 34 connected to each other. Tilts and the bar 33 moves.
