BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvement of a safety razor mainly used in ordinary households.

[0002]

2. Description of the Related Art Traditional safety razors from ancient times cannot cope with unevenness of the face during shaving because the blade is completely fixed, and shaving must be done at the same place many times. It resulted in leaving.

In order to eliminate the drawbacks of the traditional safety razor and to elastically support the elongated blade in order to cope with the irregularities of the face during shaving, the blade has the irregularities of the face during shaving. In response, a safety razor has been devised in which the blade body moves up and down elastically.

Still another conventional product has been devised in which a slender blade is formed to be extremely thin so as to be easily bent, and the blade is placed on a blade base which is also made to be flexible. In this safety razor, the blade reacts to the irregularities of the face during shaving and bends in an arc shape, so that the shaving can be performed efficiently.

[0005]

The conventional safety razor that reacts to the unevenness of the face is as described above, and the one that elastically supports the blade has a structure in which only the blade moves up and down independently. However, the structure for elastically supporting the blade body is complicated and requires a high technology for manufacturing, which results in high cost.

[0006] Also, the blades that are made thin and flexible are
If the blade is too thin, the strength of the blade will be weakened, and the blade is also thin. Therefore, there is a drawback in that the blade cannot react sufficiently to the unevenness of the face during shaving.

[0007]

The structure of the present invention is a safety razor in which an elongated shaving apparatus is attached to the upper end of a handle at a right angle to the upper edge of the elongated shaving apparatus in the longitudinal direction of the elongated shaving apparatus. , A plurality of blades 2 having a short length are provided on the base 1 through elastic portions 3, respectively, and a blade 4 having a short length is further provided on each blade base 2. Is characterized in that top plates 5 having short lengths are stacked and fixed.

[0008]

Embodiments of the present invention will now be described with reference to the drawings. The drawings shown by way of example are spare blade cartridges that are separately attached to the handle of a safety razor.

The base 1 has a frame shape and is surrounded by both side frames 6, 6, a front frame 7 and a rear frame 8. On the inner side of the rear frame 8, a beam 9 is provided in parallel with the rear frame 8 across both side frames 6 and 6. In front of the beam 9, five blades 2 having a short length are lined up in a row in the longitudinal direction of the base 1. These blades 2 are formed integrally with the beam 9 via a thin elastic portion 3. ing.
In addition, each blade 4 is provided with two holes 11, 11.

The length of the blade body 4 is slightly shorter than that of the blade base 2, and the front and rear width thereof is formed longer than the front and rear width of the blade base 2 so that the blade edge 12 projects further than the front of the blade base 2. And blade 4
Also, punch holes 13, 13 having the same size as the hole portion 11 of the blade stand are formed. The top plate 5 has the same length as the blade base 2,
The width in the front-rear direction is longer than that of the blade body 4, the front portion is bent downward and a window portion 16 is formed in that portion, and a guard portion 15 is formed further in front of this window portion 16. Two projections 14, 14 are provided from the back surface of the top plate 5.

The blade body 4 is placed on the blade base 2, and the top plate 5 is further stacked thereon, and the projections 14 and 14 are removed from the holes 13 and 1.
3 and the holes 11, 11, the end of the blade 2
The blade body 4 and the top plate 5 are fixed to the blade base 2 by crushing the protruding end portion. The blade edge 12 of the blade body is exposed from the window portion 16 of the top plate, which enables shaving. Therefore, a short shaving portion of a normal safety razor is completed on one blade 2. In the shaving apparatus of the present invention, a number of these short shaving portions are arranged side by side to form a shaving apparatus.

[0012]

The present invention is constructed as described above, and a plurality of blade bases 2 having blades 4 and a top plate 5 fixed in the longitudinal direction of the base 1 are provided with elastic portions 3 on the base 1. It is provided through.
Therefore, these blade bases 2 move independently during shaving, so that the beard can be efficiently shave while the blade moves along the unevenness of the skin.
