JPS5850756B2 - Replaceable blade razor holder - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION An object of the present invention is to provide a razor with a replaceable blade.

Conventional razors can be broadly divided into two types: cheap, disposable ones, and expensive ones that need to be sharpened.

The latter is mainly used in professional occupations such as barbering, but it is somewhat time-consuming as it must be sharpened before and during use.

In order to sharpen the blade, the thinner the blade is, the better, but there is a limit to how thin it can be when considering the feel of the blade when it comes into contact with the skin, its strength, and durability.

Also, since it was made of iron, it had to be sharpened to prevent it from rusting.

What they came up with was a razor with a replaceable blade.

By making the blade replaceable, you can save the effort of sharpening and maintain optimal sharpness.

However, what currently exists is simply a replaceable blade, and there are difficulties in supporting and mounting the blade.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to enable the blade to be replaced smoothly and easily, and to stabilize the blade.

The configuration of the present invention will be explained according to embodiments shown in the drawings.

The razor consists of a blade clamping part 1, a blade support plate 2, and a blade 3.

The blade clamping part 1 consists of a holder head 4 and a blade retaining plate 5, both of which are pivoted in the longitudinal direction slightly below the back of the blade clamping part, and the blade retaining plate 5 is centered on the axis. It can be rotated within a certain arc.

In this razor, the blade 3 and the blade support plate 2 are connected to the blade clamping part 1.
It has a means for pushing the upper part 6 apart from the axis of the holder head 4 and the blade holding plate 5 when the blade is mounted inside the blade.

The specifics of this means are shown in the drawings as follows.

That is, a through hole 7 is formed in the back of the blade clamping part 1 by opposing a recess 19 formed on the inner surface of the holder head 4 and a recess 20 formed on the inner surface of the blade holding plate 5. The through hole 7 becomes gradually narrower toward the rear.

On the other hand, an operating section 8 is integrally formed on the blade support plate 2, and the operating section 8 is exposed to the outside through the through hole 7, and is connected to the through hole T.
It can be slid inside.

The blade holding plate 5 has a protruding shaft 10 provided at the rear part 9 of the blade holding plate 5 and a shaft hole 1 provided at the rear part 11 of the holder head 4.
The tubular portion 14 fitted to the front portion 13 of the blade holding plate 5 is aligned with the internally threaded tubular portion 16 provided on the front portion of the holder head 4. Section 14.1
By inserting a male threaded pin 18 into the insertion hole 17 formed by arranging the protruding shafts 10 and the pins 18 in a row and screwing them together, It is pivoted to the holder head 4 so that it can be rotated.

When the holder head 4 and the blade holding plate 5 are pivoted together to form the blade clamping part 1, the blade support plate 2 and the blade 3 coupled thereto move inside the clamping part. Recesses 21 and 22 are provided which are continuous with the recesses 19 and 20 and open at the front so as to be slidable.

The blade support plate can be exposed from the front opening of the recesses 21 and 22.

Further, in the recesses 19, 20, 21 and 22 on the inner surfaces of the holder head 4 and the blade holding plate 5, there is a side surface of the neck 23 of the operation part 8 of the blade support plate 2 along the longitudinal direction of the blade support plate. Grooves 26 and 27 are provided for stabilizing the sliding movement of the blade support plate 2 by engaging the protrusions 24 and 25 provided thereon.

There are protrusions 28°29 at intervals on the → side of the blade support plate 2.
is provided, and the other blade body has a hole 30 through which the protrusion can be inserted.
31, and by fitting the protrusions 2B, 29 into the holes 30, 31, the blade 3 is removably connected to the blade support plate 2.

In addition, FIGS. 6 and 7 show other embodiments, in which the operation part is provided in the front part of the blade support plate and the blade support plate is pulled out and removed from the blade clamping part. This is a replaceable blade type razor holder with a replaceable blade.

Since the present invention has the above configuration, it has the effect that the blade does not shake when the blade is attached.

In other words, with conventional replaceable blade razors that do not have a blade support plate, when the blade is fed into the clamping part along the length of the razor, it does not go straight but at an angle, so when the blade is clamped, Another disadvantage is that the blade body is not parallel to the lower edge of the clamping part and must be corrected by hand.

However, in the present invention, the blade body is combined with the blade support plate, so when the blade body is fed into the clamping part, the blade moves straight without shaking, and therefore, it is installed parallel to the lower edge of the clamping part. be done.
