Abstract

PURPOSE:To enable inner blades to smoothly move up and down according to the uneveness of one's face by connecting movably a blade bed to a main body through an elastic part to stick a blade body to the plane of the blade bed. CONSTITUTION:Two blade beds 1, 1 formed in the planar fashion are coupled with a main body through elongated elastic parts 8, 8. The blade beds 1, 1 each have a central lateral stage and are formed with front and rear planes 9, 10 in front and rear of the stage. Two mounting holes 16, 17 are provided respectively in the front and rear planes 9, 9 and 10, 10 of the respective blade beds 1, 1. Projections 12, 13 extend through respective through holes 14, 15 and mounting holes 16, 17, and the tips of the projections projecting from the rear surface of the blade bed are pressed to stick ceiling plates 3, 4 and both blades 5, 6 to the upper surface of the blade bed 1. Thus, even if the edge body and blade bed are pushed rearward by a resistance force in shaving, the blade bed never makes contact with the main body by the elasticity of the elastic member.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to an improvement in a safety razor having two blades.

[0002]

2. Description of the Related Art A conventional two-blade safety razor has two blades mounted on a blade base so that the upper blade edge is slightly behind the lower blade edge. The blade was positioned and there was only one guard in front of the blade base.

[0003]

Originally, a safe razor is to shave a beard with a combination of one blade and a guard portion extending in the lateral direction in front of it, and it is not enough to shave the razor only once. So you have to shave the same place a couple of times. In order to reduce this shaving as much as possible, a two-blade safety razor has emerged, as described above, in which only two blades are stacked. However, even though the conventional product has two blades, the edges of both blades are very close to each other, so it is not enough to get the effect of shaving twice by shaving once, and still the same place I had to shave many times.

[0004]

[Means for Solving the Problems]

According to the present invention, two blades 5, 6 are provided on the upper surface of the blade base 1.
In the safety razor, in which the guards 2 are mounted with the positions thereof shifted in the front-rear direction and the guard portion 2 extends laterally in front of the blade base 1,
The upper surfaces of the two blades 5 and 6 are separate top plates 3,
The front side of the top plate 3 which is covered with the front blade 5 and which covers the front blade 5 is formed as a guard portion 7 in the rear direction 6.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT The preferred embodiment is a safety razor blade assembly that is mounted on a holder such that the blade can move relative to the body during use. The blade bases 1, 1 are formed in a plate shape and are present in two, and are connected to the main body via elongated elastic portions 8, 8. Each blade base 1, 1 has a step in the central lateral direction, and forms a front plane 9 in front of and a rear plane 10 in back of the step. The rear plane 10 has a slightly higher position than the front plane 9, and the front blade 5 is placed on the front plane 9,
A rear blade 6 is mounted on the back.

Two top plates 3, which are arranged in parallel with a space
Both ends of the reference numeral 4 are connected by side members 11 and 11, and four projections 12 and 13 are integrally provided on the back surface of each top plate portion 3 and 4. Corresponding to the positions of the protrusions 12 and 13, the blades 5 and 6 are provided with four through holes 14 and 15 respectively.
The front planes 9 and 9 and the rear planes 10 and 10 of each blade part 1 and 1
Two mounting holes 16 and 17 are provided in each. The projections 12 and 13 penetrate through the through holes 14 and 15 and the mounting holes 16 and 17, respectively, and press the tips of the projections protruding to the back surface of the blade base to thereby cause the top plate portions 3 and 4 and the double blades 5 and 5.
6 is fixed to the upper surface of the blade base 1.

Since the front top plate portion 3 of the top plate portion acts as a guard portion for the rear blade 6, its cross-sectional shape has the largest thickness on the rear side portion, and the thickness gradually decreases from there to the front. It is preferable that the shape is such that it becomes thinner.

[0008]

According to the present invention having the above-mentioned structure, the two blades are mounted with the positions thereof shifted in the front-rear direction, the guard portion 2 extends laterally in front of the front blade 5, and A rear side portion of the top plate portion 3 of the blade is formed as a guard portion 7 of the rear blade 6. Therefore, this safety razor is equipped with two sets of one guard part for one original blade of the safety razor, and it is possible to obtain the same effect as shaving twice by shaving once. it can. Further, since the top plate portion 3 of the front blade 5 is used as it is as a guard portion, there is an effect that a new guard portion for the rear blade is not required.
