Description

[Detailed description of the invention] The present invention relates to a convenient two-blade razor that has a structure that eliminates the spacer that is used to maintain a constant distance between the upper blade body and the lower blade body, making it possible to fix the two blades. .

Conventionally, in a two-blade convenient razor, a spacer had to be interposed between the upper blade and the lower blade to maintain a necessary distance.

The spacer also serves to fix the lower blade, and for this reason as well, the spacer is necessary in two-blade razors.

However, when shaving, the spacer prevents shaving shavings from being removed, and the shaving shavings get stuck between the spacer and the blade, causing the blade to become clogged.

In addition, since the two blade bodies also require a spacer component, the number of components increases accordingly, resulting in higher costs, and there are also problems in that assembly becomes troublesome.

The present invention was developed to eliminate the above-mentioned drawbacks.It has a structure that does not require a spacer, and allows two blades to be fixed, allowing shaving debris such as beard to be removed without clogging.
The purpose is to obtain a convenient single-blade razor.

That is, the present invention provides a cylindrical fitting protrusion whose protruding portion is larger than the thickness of the lower blade body and has a through hole inside the support base, and the lower blade body has a fitting hole in the cylindrical fitting protrusion. mated,
A part of the cylindrical fitting protrusion is pushed out onto the lower blade body to fix the lower blade body, and an upper blade body having a through hole is placed on the cylindrical fitting protrusion to open the through hole and the through hole. The support plate and the presser plate are fixed together after the bar-shaped protrusion of the presser plate having the rod-shaped protrusion is inserted into the through hole of the upper blade body and the through hole of the cylindrical fitting protrusion. It is.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. A lower blade body 4 having a fitting hole 5 is fitted into a cylindrical fitting protrusion 2 having a through hole 3 provided on a support base 1. A part of the fitting protrusion 2 is pushed apart from the lower blade body 4 to fix the lower blade body 4.

In this case, the cylindrical fitting protrusion 2 is made of a material that can be pushed and expanded, such as plastic, and in order to be pushed and expanded onto the lower blade body 4, press working or heat or ultrasonic processing is performed.

In the embodiment of the present invention, as shown in FIG. can be fixed to the support 1.

In this case, the lower blade body 4 is fixed to the support base 1 and at the same time has a resistance force applied to the blade edge from below to above during shaving.

Further, as shown in FIG. 5, the side portion 2b of the cylindrical fitting protrusion 2
The lower blade body 4 can also be fixed to the support base 1 by pushing outward.

In order to spread the opening, the side portion 2b of the cylindrical fitting protrusion 2 can be pushed outward by applying pressure from the inside of the through hole 3.

In this case, as shown in FIGS. 9 and 10, a stepped rod-shaped protrusion 8 made of a cylinder having a diameter that matches the diameter of the through hole 3 and a slightly larger diameter is provided on the presser plate 9. By inserting this into the through hole 3, the side portion 2b of the cylindrical fitting protrusion 2 is pushed outward and the lower blade body 4 can be fixed to the support base 1.

Furthermore, as shown in FIG. 6, it is of course possible to fix the two in combination.

Note that it is preferable that the cylindrical fitting protrusion 2 is pressed and expanded as little as possible in order to keep the upper surface of the cylindrical fitting protrusion 2 at a constant level.

The upper surface of the cylindrical fitting protrusion 2 serves as a stand for the upper blade 6 as it is, and when the upper blade 6 is placed on the cylindrical fitting protrusion 2, there is no space between it and the lower blade 4 that was fixed earlier. There is a gap between.

That is, the above-mentioned gap is formed between the upper blade body and the lower blade body, which was maintained by interposing a spacer in the conventional two-blade convenience razor.

The upper blade body 6 is provided with a through hole 7 so as to match the through hole 3.

Then, as shown in FIGS. 7 to 10, the rod-shaped protrusion 8 provided on the presser plate 9 is inserted into the through hole 7 and the through hole 3, and the upper blade body 6
is fixed between the cylindrical fitting protrusion 2 and the holding plate 9, and the through hole 3
The tip of the rod-shaped projection 8 that protrudes below the support base 1 is flattened by means such as ultrasonic welding, and the presser plate 9 is fixed to the support base 1.

In addition, an adhesive may be used as the fixing means, or the support base and the presser plate may be formed integrally with a self-hinge and simply fit together.

According to the present invention, it is possible to fix two blades with a structure that eliminates a spacer, so a gap is created between the upper blade body and the lower blade body, and shaving debris such as whiskers can be smoothly removed without clogging.

Further, since one spacer component is omitted, costs can be reduced, and assembly is also simple.
