JPS5835186Y2 - Replaceable blade razor holder - Google Patents

Description

[Detailed description of the invention] The object of the 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 the barber industry and other professions, but it is somewhat time-consuming as it requires sharpening 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 eliminate the hassle of sharpening and maintain optimal sharpness.

The purpose of the present invention is to facilitate the replacement of this blade.

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

The razor consists of a blade holder 1 and a blade 2.

The blade attachment part 1 consists of a holder head 3 and a blade holding plate 4, both of which are pivoted in the longitudinal direction slightly below the back of the blade attachment part 1.

That is, the blade holding plate 4 has a protruding shaft 5 provided at the rear of the blade holding plate fitted into a shaft hole 6 provided at the rear of the holder head, and a tubular portion 7 provided at the front of the blade holding plate. A pin 9 is provided at the front of the holder head and is aligned with the female threaded tubular part 8, and is male threaded in the insertion hole formed by arranging both the tubular parts 7 and 8 in a row. By inserting and screwing together the protruding shaft 5 and the pin 9, the protruding shaft 5 and the pin 9 are pivotally attached to the head of the holder so that they can be rotated within a certain arc around the axes of the protruding shaft 5 and the pin 9.

A part of the inner surface of the holder head 3 and the blade holding plate 4 is made into a recess, and by pivoting the two, a groove 10 is formed on the back of the blade clamping part, and the blade clamp is inserted into the groove 10. A wedge body 11 is rotatably pivoted to the back of the blade holder so as to spread out the back of the holder.

Since the present invention has the above configuration, it has the following effects.

Conventionally, a tapered hole was provided at the back of the clamping part, and the blade was attached and detached by sliding a slider back and forth within the hole. There is a drawback that the slider becomes difficult to slide if dirt or dust adheres to the slider.

Since the present invention uses the wedge body to attach and detach the blade as described above, it does not have the drawbacks of the conventional blade and is convenient to handle.
