Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art In a conventional two-blade safety razor, upper and lower blades and a spacer between them are sandwiched between a blade base and a top plate, and the top plate has a plurality of overlapping blades. Convex covering portions are provided along the edge of the blade at intervals.

[0003]

Although such a covering portion takes into consideration the safety during use, in the above-mentioned two-blade safety razor, the covering portion is only on the upper blade and not on the lower blade. So, the safety effect was lessened. It is an object of the present invention to improve the safety of a two-blade safety razor by improving the formation position of the covering portion.

[0004]

DISCLOSURE OF THE INVENTION The present invention is directed to an elongated blade base 1.
Two blade mounting surfaces 2 and 11 are provided in parallel with each other in the longitudinal direction of the upper surface of the blade, and the leading blade 3 and the trailing blade 4 mounted on these blade mounting surfaces are respectively attached by the blade holding portions 12 and 13. In a fixed two-blade safety razor, a guard part 1 extending in parallel with the leading blade 3 at a distance in front of the leading blade 3.
7 and the upper surfaces of the double-edged clasps 12, 13 have double-edged edges 14, 1
5, the protrusions 7, 8 and 9 projecting higher than 5 are provided so as to be in a line in a direction perpendicular to the blade edge, and the protrusions 7 in this line are
8, 9 are provided in parallel in a plurality of rows on the upper surfaces of the guard part 17 and the double-edged clamping parts 12, 13.

[0005]

Embodiments of the present invention will now be described with reference to the drawings. The tool rest 1 is formed of plastic integrally with the handle 16. The two blade mounting surfaces 2 and 11 are formed on the upper surface of the blade base 1 in parallel with the longitudinal center line of the blade base 1 as a boundary. Both the blade mounting surfaces 2 and 11 are inclined surfaces that rise forward. Therefore, the boundary between the two blade mounting surfaces 2 and 11 forms a step.

An elongated whiskers discharge hole 6 is provided on the trailing blade mounting surface 11 along the step. Further, an elongated whiskers discharge hole 5 is provided along the front edge of the blade stand 1 in the front portion of the leading blade mounting surface 2. The front portion of the whiskers discharge hole of the leading blade 3 becomes a guard portion 17 extending in the longitudinal direction.

A top plate 20 integrally formed of plastic is placed on the two blades 3 and 4, and some projections 21 formed on the back surface of the top plate penetrate through the circular holes of the blades to form a hole 22.
And the top plate 20 is attached to the blade stand 1. The top plate 20 is composed of both side plate portions 23, 23 and two parallel blade holding portions 12, 13 connecting between the both side plate portions, and these two blade holding portions 12, 13 are the leading blade 3 and the trailing blade. It serves to fix the blade 4 on the blade mounting surface.

Projections 7, 8 and 9 are provided on the upper surfaces of the guard portion 17 and the double-blade holding portions 12 and 13 so as to form a line in a direction perpendicular to the blade edges 14 and 15. The projection 7 provided on the guard portion 17 has a short length, but the double-edged clasp portions 12, 13 are provided.
The protrusions 8 and 9 provided on the blade are formed to be long over the entire front and rear width of the blade holding portions 12 and 13. These protrusions 7,
8 and 9 project higher than the two blade edges 14 and 15.

The present invention is constructed as described above, and the projections 7, 8 projecting higher than the double-edged edges 14, 15 are provided on the upper surfaces of the guard part 17 and the double-edged clamping parts 12, 13. 9 are provided so as to form a line in the direction perpendicular to the blade edge, and the protrusions 7, 8 and 9 in this line are provided in parallel in a plurality of lines. Therefore, since these projections 7, 8 and 9 have the same effect as when the two blade edges 5 and 6 are covered at regular intervals, the safety of the two-blade safety razor can be enhanced.
