The present invention relates to a manual safety razor, and in particular, by allowing the rotational force of the driving roller which rotates in contact with the skin to be transmitted to the rotary blade having a spiral blade, it is easy to shave without the need for a separate electric power source A manual safety razor that makes it possible.

Commonly used razors are generally divided into electric shavers (hereinafter referred to as electric shavers) using electric or battery, and manual razors which replace disposable razor blades. By covering the surface of the rotating blade with a protective net, the user's skin could be protected from the blade, while the blade was rotated at high speed to allow for a quick shave.

However, such a shaver is configured to rotate the built-in motor using electricity or batteries (battery), so if the power is cut off during use, the beard will be gathered between the guard net and the blade, which can lead to very bad feelings. In terms of the structure, the volume of the motor storage space for rotating the blade portion has to be secured, thereby increasing the volume, resulting in inconvenience in carrying.

In addition, passive shavers have the advantage of being hygienic, easy to carry, and can be used anywhere, but the razor blades are exposed outside the fixed shaver. Not only does it occur frequently, but in order to shave smoothly, it has to be applied to the skin with lubricating substances such as soap and lotion. Most of them are used for one-time use, and in addition to the difficulty of recycling, the treatment of the shaver that was used requires a careful treatment out of reach of children.

The present invention has been devised to solve the above problems, it can be used easily in any place without using an electric power source, the rotary blade installed inside the protective net by the drive roller is driven in contact with the skin Its main purpose is to provide a safety razor that can effectively prevent the case of damaging the shaving part during use by being able to be driven directly.

Another object of the present invention is to arbitrarily adjust the rotational speed of the rotary blade to appropriately use according to the user's taste, and another object is a thin, easy to carry, yet extremely monotonous configuration, the durability of the razor semi-permanently To keep it.

Hereinafter, the present invention for achieving the above object will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing the overall appearance of the present invention, FIG. 2 is a cross-sectional view taken along line II-II of FIG. 1 for explaining the operation of the present invention, and FIG. 3 shows the overall configuration of the rotary blade and the driving body. As the exploded perspective view of the drive unit, according to the safety razor of the present invention, the helical blade 16 and the drive body 15 having the drive gears 12 connected to the drive shafts 13 on both sides thereof so that the drive rollers 11 can be fitted. The rotary blades 20, which are projected to the drum-shaped rotating body 17 at a predetermined interval, can be engaged with each other, and are embedded in the razor body 10.

In addition, the driving roller 11 is inserted and coupled to the outside of the drive gear 12 to form a part exposed to the outside through the roller insertion hole (10a) perforated on the razor body 10, the drive roller 11 The drum-type rotary body 17, which receives the rotational force through the driving gear 12 and the interlocking gear 18 in accordance with the rotation of the), has a protection net so that the spiral blade 16 protruding from the surface thereof does not directly touch the user's skin. 21) is protected.

The above-mentioned driving gear 12 is provided with a stopper 14 for preventing the reverse rotation to be resilient, which prevents the phenomenon that the drum-type rotating body 17 and the driving body 15 is operated in the opposite direction of rotation due to the stopper 14. The elasticity is provided to a part of the driving roller 11 driven by being in direct contact with the skin to prevent skin damage and to relieve discomfort caused by contact.

On the other hand, the drive shaft 13 and the interlocking shaft 19 extending from the drive body 15 and the drum-shaped rotary body 17 are respectively supported on the inner surface of the shaver body 10, the drive roller to drive the body in contact with the skin Rotation of the (11) is changed to the rotational movement of the drum-shaped rotating body 17, the shaving by the spiral blade 16 is made.

As shown in FIG. 2, the shaver main body 10 is provided with a fastening groove 22 so as to fit the handle portion 23 so that the fastener 24 formed at the tip of the handle portion 23 at the time of use is simply provided. In order to be assembled, it is possible to provide convenience of portability by storing them separately from each other during storage.

According to the above, in FIGS. 2 to 3, the driving body 15 and the drum-shaped rotating body 17 are directly coupled as the gears 12 and 18 to rotate in opposite directions. According to the embodiment, although not shown, it may be possible to rotate in the same direction by providing a transmission gear between the driving body 15 and the drum-shaped rotating body 17. However, the drum-type rotating body may be used when the transmission gear is installed. (17) It would be desirable to arrange the direction of the spiral blade 16 provided as the surface in the opposite direction as shown in the figure.

The present invention configured as described above, after assembling the razor main body 10 and the handle portion 23, the front surface of the razor main body 10 is in close contact with the portion to be shaved lightly pushed, roller insertion hole (10a) As the driving roller 11 protruding along the skin rotates in contact with the skin, the drum-shaped rotor 17 is rotated in the rotational direction of the driving roller 11 or in the opposite direction thereof, so that the drum-shaped rotor 17 Shaving can be performed by the spiral blade 16 protruding at regular intervals from the surface.

In this case, when the driving roller 11 in contact with the skin is formed of a rubber material having excellent elasticity in order to prevent damage to the skin, the elasticity of the built-in stopper 14 is improved along with the elasticity of the contact, thereby eliminating discomfort. By installing the porous guard net 21 for the protection of the spiral blade 16, it is possible to shave with an increase in cutting force, and in particular, it is possible to manufacture with a soft edge by a simple structural coupling is easy to carry It is very useful to be able to use without regard to place.

Claims (1)

The stopper 14 is attached to a pair of drive gears 12 to which the drive rollers 11 are coupled, and then connected to each other by a drive shaft 13. The lower part of the drive gear 12 is spirally formed on the surface of the drum-shaped rotor 17. The rotary blade 20 protruding the blade 16 at regular intervals is installed so as to be engaged with each other by the interlocking gear 18, and the driving roller with a roller insertion hole 10a formed at the upper end of the razor body 10.
