Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric hair clipper blade used for cutting hair.

When trimming with the blade of a conventional electric hair clipper, the lower blade is flat, so (a) it cannot adapt to and adhere to the curvature or undulations of the scalp, and the hair is stuck to the blade. It runs away more and is more difficult to mow.

(b) Since the grass can only be cut to a uniform size, even a highly skilled person will have a difference in the cutting edge and cannot do the so-called ``shading'' without using scissors to compensate.

(c) Both ends of the blade dig into the scalp, causing the area to be cut too deeply and the cut surface to be uneven.

(d) The efficiency of mowing is poor due to the cause of (a) and the consideration to avoid the consequences of (b) and (c) as much as possible.

It has the following disadvantages.

The present invention has been made in view of the conventional situation, and will be explained below with reference to embodiments of the drawings. In Figs. 1, 2, and 4, 1 indicates a blade portion.
1a and its retaining part 1b (here, the "retaining part" refers to the blade part 1
Lower base blade 2 consisting of (refers to the lower base blade part excluding a)
is an upper blade which is superimposed on the lower base blade 1 via the mounting rail 3, and 4 is a blade seat which is further fitted into the upper blade 2, and by these connections, each bolt hole 1f, 2a, which corresponds to the top and bottom is formed. The clipper main body is assembled by inserting a mounting bolt 5 into 4a from below, and screwing a blade holding nut 7 onto the mounting bolt 5 from above via a blade holding spring 6.

That is, in terms of component configuration, the present invention is the same as the conventional electric hair clipper.

In the present invention, the shape of the lower base blade 1 is devised, and the thick cross section of the lower base blade 1 is changed to a conventional planar shape, and slight edges are formed on each side end of the lower base blade 1. It is characterized in that it is formed into an inverted mountain shape 1d so that the central part between both end portions forms a ridgeline of a mountain, leaving a portion 1c.

Note that in FIGS. 1 and 2, 1e is a small protrusion provided on the edge of the edge 1c.

As described above, in the present invention, the wall thickness cross section of the lower base blade 1 is formed into an inverted mountain shape 1d such that the central part between both side ends forms a ridgeline of a mountain, leaving the edges 1c at both side ends. Therefore, if the lower base blade 1 is tilted to either side, it will form an inverted mountain shape 1d as shown in FIG.
One of the curved surfaces of the blade fits closely along the scalp surface, thus eliminating the drawback (a) listed at the beginning, and as a result of the above-mentioned cross-sectional structure, the blade portion 1a also gradually curves in height toward the center. , it also eliminates the drawback of (b) without creating a cutting boundary.

To explain this in more detail, hair is cut by the upper and lower blades working together, but in the present invention, the height of the lower blade 1a gradually increases in height as it approaches the upper part of the scalp. As a result of this, the amount of remaining hair naturally increases from the hem to the upper part of the scalp without creating a step, allowing for a shading finish.

Moreover, since the inverted mountain shape 1d extends not only to the blade part 1a but also to its retaining part 1b (that is, to the entire lower blade part 1), when advancing while applying the blade part 1a to the scalp surface, the guidance is stable and reliable. can do.

Furthermore, since the edges 1c are left on each side end of the lower blade 1, when using normal clippers to trim the side and back of the head below the cutting area by the blade of the edge 1c, Since the depths of the holes are the same, there is no difference in level, which eliminates the drawback (c) above.

In addition, as shown in FIGS. 1 and 2, the edge 1c
If a small protrusion 1e is provided on the edge of the head, when the hair needs to be shaved to the top of the head, such as in the case of elderly people, the small protrusion 1e will dig into the scalp, causing the cut surface to be damaged due to over-cutting. It is possible to more effectively prevent the formation of steps.

As is clear from the above, according to the electric hair clipper blade of the present invention, even an amateur can cut and style hair simply and quickly without requiring much skill, and can also cut hair in a particularly detailed manner (such as shading). Since such a hair styling effect can be obtained naturally without having to do so, even elderly people with weakened eyesight can work without wearing reading glasses, which is truly advantageous.
