Description

[Detailed Description of the Invention] This invention relates to an electric hair clipper that can easily and efficiently perform trimming around the ears, trimming edges, etc.

Conventionally, in order to trim around the ears with electric clippers, the electric clippers are tilted and moved from behind the ears to the front along the base of the ears to trim or align the edges of the ears. In this case, since the left and right sides of the tip of the main case of the electric clipper are formed as straight flats in the front-rear direction, the left or right side facing the ear base will float above the ear base, resulting in an unstable position. It is not easy to move the hair accurately along the base of the ear, and it is especially difficult for amateurs to trim the hair at this point.

This invention focuses on this fact and attempts to provide an electric hair clipper that allows even an amateur to easily and efficiently trim and trim around the ears.

The details will be explained below based on the drawings. The drawing illustrates an electric hair clipper according to this invention.
The main body case 1 of this device consists of upper and lower plastic cases 1a and 1b that are split into two halves, and inside the lower case 1b, in order from the tip, there is a clipper-type reaping device 2, a plastic vibrator 3 that drives this, and a motor. 4 and a storage battery 5, and an upper case 1a is screwed onto the upper case 1a, so that it has a long box-like structure that is long in the front-rear direction.

The vibrator 3 has a thick rear wall 3a fixed to the lower case 1b, and a thick front wall 3 having a forwardly protruding interlocking arm 3d connected to the movable blade 2a of the reaping device 2.
b are connected by thin left and right side walls 3c and 3c to form a parallelogram in plan view, and the crank pin 8 is engaged with a vertically long long groove 7 formed on the rear surface of the front wall 3b. By rotating the front wall 3b at high speed with the motor 4, the front wall 3b vibrates back and forth in the left and right directions through elastic deformation of the left and right side walls 3d.

The reaping device 2 includes a fixed blade 2 mounted on a fixed blade support 10 that is removably pivoted to a support shaft 9 on the lower case 1b.
a is caulked and fixed, and the movable blade 2b, which is caulked and fixed to the movable blade support 11, is attached to the upper surface of the fixed blade 2a by a helical spring 14 attached to the fixed blade support 10 via a support shaft 13. The fixed blade 2a and the movable blade 2b are pressed and biased to be slidable, and the cutting edges of the fixed blade 2a and the movable blade 2b protrude forward from the tips of the upper and lower cases 1a and 1b. The protrusion 15 protruding from the upper surface of the movable blade support 11 is engaged with the tip engagement hole 16 of the interlocking arm 3d of the vibrator 3, so that the horizontal vibration of the vibrator 3 is linked to the movable blade 2b. .

In the electric hair clipper having such a structure, this invention is applied to the left and right side surfaces 1c and 1 near the tip of the main body case 11.
Guide protrusions 17 for following the ears are provided protruding from c.
The guide protrusion 17 shown in FIGS. 3 and 4 consists of a semicircular disk portion 17a having a semicircular shape in plan view, and a handle portion 17b protruding from the right edge of the semicircle toward the inside of the main case 11. The portion 17b is inserted into the stepped end portion 18a of the boss 18 that projects downward from the inner surface of the upper case 1a, and is held between the end surface of the end portion 18a and the inner wall 19 of the lower case 1b that abuts against the stepped end portion 18a. fixedly, and the semicircular portion 17a is attached to the upper and lower cases 1a/1.
It protrudes outward from between the abutting surfaces of b. Note that the boss 18 and the inner wall 19 are butted against each other.
Tapping screws 20 are screwed into the housings 1 and 2 to connect the upper and lower cases 1a and 1b.

In such a case, when trimming or aligning the edges around the ears, use the guide protrusion 1 along the ears as shown in Figure 5.
By sliding the clipper 7 forward from behind the ear along the base of the ear, the entire clipper can be moved stably and smoothly around the ear, and the moving operation is also simplified. Since the ear guide protrusions 17 are provided on both left and right side surfaces 1c of the main body case 1, it is possible to trim or align the edges around the left and right ears under the same conditions.

FIG. 6 shows another modified embodiment of the guide protrusion 17, in which the guide protrusion 17 is formed into a roll shape and is installed in the upper and lower cases 1a and 1b so as to freely rotate around the vertical axis 21. At the same time, a part of this circumference protrudes outward from between the notches in the abutting surfaces of the upper and lower cases 1a and 1b. According to this, the guide protrusion 17 rotates while sliding on the base of the ear, thereby reducing friction. There is almost no resistance, and movement around the ears is extremely smooth and light.

The guide protrusion 17 may be made of soft rubber or soft plastic, and the guide protrusion 17 may be shaped not only in a semi-disc shape but also in a hemispherical shape so as to feel good against the ear and not cause discomfort. is preferred.

Note that the guide protrusions 17 are not only formed separately from the main case 1 as in each of the above embodiments, but also formed by bulging a portion of the left and right side surfaces 1c and 1c of the main case 1 outward. Including those who do.

As explained above, the electric clipper of this invention has the left and right sides 1c and 1c near the tip of the main body case 1.
Guide protrusions 17 and 17 that can be placed along the ears.
Since it is a protruding part, even an amateur can trim the edges of the left and right ears and align the edges very well and easily, which is advantageous in that it is easy to use.
