Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an electric hair clipper type hair clipper used in home hairdressing.

[Background Art] In order to cut around the ears as shown in FIG. 9a using a conventional electric clipper-type hair cutter, as shown in FIG. 9b and c, the hair cutter 20 is
The edge of the blade is set at α and β degrees in the plane along the skin and in the plane perpendicular to the skin, respectively (α and β are 30 to 45 degrees).
Since it is necessary to move the hair cutter 20 forward with the hair cutter 20 tilted, the tilt of the hair cutter tends to become unstable, making it difficult for beginners to handle. For this reason, many people cut by applying the full width of the cutting edge to the skin at right angles to the skin, and in that case, as shown in Figure d, the width of the cut becomes too wide, making it difficult to cut in a curved line, and cutting more than necessary. There was a risk of cutting in too much.

As a countermeasure to this problem, Japanese Utility Model Publication No. 52-39547 and Japanese Utility Model Application No. 60-2472 disclose that the effective width of the cutting edge is narrowed by covering part of the blade with a cover, making it easier to cut around the ears. However, in the conventional cover, as shown in FIG. It was not easy to use because it caused a situation where hair got into the gap G and got caught without being cut.

[Purpose of the invention] The present invention was devised in view of the above points, and its purpose is to provide a hair cutter that is easy to use and allows even beginners to easily cut around the ears.

[Disclosure of the invention] The present invention has a comb-shaped fixed blade and a comb-shaped movable blade that reciprocates in sliding contact with the fixed blade, and a cover attached to the blade is attached to each side end of the blade. In a hair cutter that is movable between two positions that expose comb teeth of a certain width, a locking member is provided to lock the cover in the two positions, and the side edge of the cover in the locking position is attached to the fixed blade. It is characterized by the fact that it matches one of the comb teeth, and by covering part of the comb teeth with a cover, the effective cutting width can be narrowed and the usability can be improved. It can be switched to the left or right, and even when switched to the left or right, the side edge of the cover matches one of the comb teeth of the fixed blade, so there is no gap that could trap hair. It is something.

The present invention will be described in detail below based on the illustrated embodiment. In FIGS. 1 to 3, a cylindrical attachment 3 is attached to a recessed step 2 formed in the front part of the hair cutter body 1. , attachment 3
A comb-shaped fixed blade 4 and a comb-shaped movable blade 5 that reciprocates in sliding contact with the fixed blade 4 are attached to the front end of the hair cutter main body 1 protruding from the front end opening.

A cover 6 having a U-shaped cross section is slidably attached to the above-mentioned double-edged part, and its width is equal to that of the fixed blade 5.
The engagement protrusions 7 and 8 formed at the edges are formed by grooves provided along the front edge on the back surface of the front end of the attachment 3. It is slidably engaged with the guide rail 9, and the cover 6 is then click-locked at either side end position of the blade part at both ends of the cover 6 and the attachment 3, as shown in FIG. 3b. A protruding click engaging portion 10 is provided for this purpose.

Note that the cover 6 is not attached directly to the hair cutter body 1, but is attached to the attachment 3, and the cover 6 is attached to the first attachment.
As shown in Figure b, the attachment 3 is detachable from the hair cutter body 1 by means of an engaging rib 11, which makes it easy to switch between a detailed cut using the cover 6 and a full cut without using the cover 6. I have to.

When in use, the cover 6 is slid to either the left or right end as shown in FIG. 4a or b. In this case, as shown in Figure 5a, first move the cover 6 to one end and trim the front side of the ear, then move the cover 6 to the other end and trim the back side of the ear, as shown in Figure 5b. If you try to reap the
The hair can be finished in a round shape as shown in figure c, and even if the inclination of the hair cutter main body 1 becomes unstable, there is no risk of cutting the hair unnecessarily because of the cover 6.

Further, as shown in FIG. 7, since the side edge 6a of the cover 6 is aligned with one of the comb teeth 4a of the fixed blade 4 at the locking position of the left and right ends, that is, the gap This prevents hair from getting caught between the cover 6 and the comb teeth of the fixed blade 4.

As shown in FIG. 4c, if the cover 6 is fixed near the center of the fixed blade 4, it is possible to easily cut in a narrow area directly above the ear. Furthermore, as shown in FIGS. 6a and 6b, even when cutting is performed by applying the cutting edge to the skin at right angles, the effective width of the cutting edge is reduced by the cover 6, so as shown in FIG. , it can be finished so that the corners of the cut marks are not noticeable. The appropriate difference D between the width of the fixed blade 4 and the cover 6 is 8 mm ± 2 mm; if it is narrower than this, the number of cutting operations will increase, making handling more troublesome; on the other hand, if it is too wide, The disadvantage is that the finish becomes angular.

[Effects of the invention] As described above, the hair cutter according to the invention has the following advantages:
Since the cover attached to the blade is movable between two positions exposing comb teeth of a constant width at each side end of the blade, it is possible to effectively cut by covering part of the comb teeth with the cover. Not only can the width be narrowed, but the usability can be switched freely, so even beginners can easily and beautifully finish the cut around the ears. When the cover is locked in place, the side edge of the cover matches one of the comb teeth of the fixed blade, causing hair to get caught between the side edge of the cover and the comb teeth of the fixed blade. It has the advantage that it can be used comfortably without causing any gaps.
