JPH08112462A - Outer blade of reciprocative electric shaver - Google Patents

Abstract

PURPOSE: To provide a reciprocative electric shaver which can surely cut frizzy beards and long beards in such a way as to erect and dress well the beards by the slots made in the region not sliding on an inner blade and introduce the beards into the slots made at the side in the region sliding on the inner blade so as to cut them. CONSTITUTION: An outer blade 2 has a region A and a region B each provided with slots and is stretched in arch shape at the head part of a reciprocative electric razor 1. An inner blade 4 is provided, being pressure-welded with a spring or the like to the inner face side of the outer blade 2. The slot 3 made in the region A is positioned just in the position of the side and besides slides on the inner blade 4, when the outer blade 2 is stretched at the head part of the razor 1. The slot 3 in the region B is positioned in the region not sliding on the inner blade 4. At shaving, beards are erected and trimmed by the slots 3 in the region B, and next they are introduced into the slots 3 in the region B, and they are cut by the sliding with the inner blade 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer blade of a reciprocating electric shaver.

[0002]

2. Description of the Related Art In the outer blade of a reciprocating electric shaver,
There is known an outer blade having a long hole formed therein so that it can be easily cut when shaving a whisker or a long beard. For example, FIG. 6 is a plan view showing a state in which the outer blade 2 of the conventional reciprocating electric shaver is developed. The outer blade 2 is stretched in an arch shape on the head portion of the reciprocating electric shaver 1 shown in FIG. 7 or 8. An inner blade that reciprocates is provided on the inner surface side of the outer blade 2 while being pressed against it by a spring or the like. Here, although not shown, a short hole for introducing and cutting a beard is formed near the peak of the outer blade 2. The whiskers introduced are cut by the cooperative action of the inner and outer blades. Further, a long hole 3 is formed in a region A near the hillside of the outer blade 2 stretched in an arch shape. The long hole 3 is formed in a region where the outer blade 2 is in sliding contact with the inner blade, and is used for cutting a whiskers or long whiskers. The length of the long hole 3 is about 1.5 to
It is 2 mm. However, the long hole 3 is the outer blade 2
Since it is formed in the area where the inner blade and the inner blade are in sliding contact with each other, it is not possible to fully raise the hair or adjust the beard direction
The beard had been introduced into the long hole 3. As a result, the beard could not be shaved from the root, and the shave could be left behind.

There is also known a device in which a whisker and a long beard are sufficiently raised to be introduced into a long hole. For example, Japanese Unexamined Patent Publication No. 59-160486 discloses an outer blade in which a central portion of a long hole formed in the outer blade is raised to form a rib, and the rib is raised by this portion. However, there is a problem in that the outer blade having the ribs formed therein has complicated processing.

[0004]

Therefore, the present invention is
It is an object of the present invention to provide an outer blade of a reciprocating electric razor capable of sufficiently raising a whiskers or a long beard with a simple structure and introducing the whiskers into a long hole for cutting.

[0005]

In an outer blade of a reciprocating electric shaver stretched in an arch shape, a region having a region in sliding contact with the inner blade and a region not in sliding contact with the inner blade, and a region in sliding contact with the inner blade. In the area that does not slide on the hillside and the inner blade that is continuous with the hillside,
Form a long hole.

The elongated hole may be formed separately in the hillside portion of the area that is in sliding contact with the inner blade and in the area that does not slide in contact with the inner blade that is continuous with the hillside, or may extend over two portions. May be integrally formed.

[0007]

According to the present invention, when shaving a whisker or a long beard, the whiskers are first raised and trimmed by the long holes formed in the area not slidingly contacting the inner blade, and then the area slidably contacting the inner blade is prepared. A whisker is introduced into the long hole formed on the hillside to cut.

Further, since the outer blade of the present invention does not have the ribs as described in the prior art, it has a simple structure and can be easily processed.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. In addition, in this embodiment, the same reference numerals are used for the respective components described in the section of the conventional technique. As shown in the development view of FIG. 1, the outer blade 2 in this embodiment has elongated holes 3 formed in the regions A and B, respectively. The outer blade 1 is stretched in an arch shape on the head portion of the reciprocating electric shaver 1 shown in FIG. 2 or 3. An inner blade 4 that is reciprocally driven is provided on the inner surface side of the outer blade 2 while being pressed against it by a spring or the like. Here, although not shown, a short hole for introducing and cutting a beard is formed near the peak of the outer blade 2. The introduced whiskers are cut by the cooperation of the inner blade 4 and the outer blade 2.

Here, as shown in FIGS. 4 and 5,
The long hole 3 formed in the area A is provided with the outer blade 2 and the razor 1
When it is stretched on the head part of the above, it is located just on the hillside, and is located in a region where the outer blade 2 is in sliding contact with the inner blade 4. The elongated hole 3 formed in the region B is located in a region where the outer blade 2 does not slidably contact the inner blade 4. The long holes 3 formed in the regions A and B have the same shape and have a length of 1.5 to 2 m.
m, and the width is 0.2 to 0.3 mm.

When using this outer blade 2 to shave a whisker or a long beard, first, the whiskers are raised by the long holes 3 formed in the area B to be adjusted, and then the long holes 3 formed in the area A. Introduce a beard to cut.

The long hole 3 can be integrated over the area A and the area B. In this case, beard raising and cutting can be performed more smoothly and continuously.

[0013]

According to the present invention, when shaving a whisker or a long beard, first, the whiskers are raised by a long hole formed in a region not slidingly contacting the inner blade, and then slidably contacting the inner blade. A whisker is introduced into the long hole formed in the hillside of the region to cut. As a result, even if the beard is uneven, the orientation can be adjusted first and then shaving can be performed, so that the beard can be shave cleanly and the load on the blade can be reduced.

Further, since the outer blade of the present invention does not have the ribs as described in the prior art, it has a simple structure and can be easily processed.
