DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety razor which can be used for shaving, body hair treatment and the like comfortably.

[0002]

2. Description of the Related Art As shown in FIG. 11, a conventional safety razor is a two-blade replaceable blade type, and a fixed type and a swing type have been widely used. That is, the handle 1 is formed in a straight or inwardly bar-like shape having a warp.
The mounting member 3 is provided at the distal end of the support member 2 while maintaining an angle that intersects the support member 2 protruded from the distal end of the handle member 2 and bent inward by approximately 30 ° in the longitudinal direction of the handle 1. The center of gravity was provided at or near the center of the handle 1.

[0003] In the spare blade, that is, the blade holder 4, two blades, an upper blade and a lower blade, are held in parallel between the safety rod and the blade angle stabilizing plate, and the skin blade angle is about 30 °. Angle was maintained.

[0004] The conventional safety razor has the following disadvantages. In use, it is due to experience, feeling and care, rough and beards tend to remain, and the remaining beards are shaved neatly, that is, reverse shaving. Reverse shaving is a process in which the razor is turned upside down, and from the bottom up, while changing the direction angle, in the process of repeatedly shaving a complex growing beard, the sharp edge causes damage to the skin, soreness, bleeding It was accompanied by discomfort such as burning and burning after shaving.

[0005] The reasons for this are that, because of the structure described above, (1) As shown in FIG. Lower blade 8. Upper blade 7. This is a state in which the blade angle stabilizers 5 are sequentially contacted and closely attached. In order to perform such an operation, the elbow is stretched, and it is difficult to perform a smooth operation on each part of the undulating face. And because the tip is light, it is easy to apply force to the cutting edge,
This is because they come into strong contact. (2) For a smooth operation, a safety bar 6 is attached to the skin surface 10. Lower blade 8. The upper blade 7 contacts in order, but the blade angle stabilizer 5 is operated without contacting the skin surface 10, and as shown in FIG. 12, the blade stands on the skin surface 10,
This is because the sharpness is reduced.

In view of the above technical problems, the present invention provides a safety razor that is easy to use, secures safety without damaging the skin, shave taste without leaving shaving, and soft feel to the skin. is there.

[0007] The above-mentioned objectives, ease of use, safety, and how to shave the beard softly were considered. To make the safety razor easier to use, shape it to match the natural movement of the human body. That is, the handle 1 is formed in a bar shape having a warp outward, whereby the handle 1 absorbs and eliminates unpleasant pressure applied to the cutting edge. Since the weight of the cutting tool is required in proportion to the mass of the object, the supporting member 2 is provided by protruding inward from the tip of the handle 1 having a center of gravity at the tip and bending inward. The mounting member 3 is provided at the tip of the support member 2 so as to be in flat contact with the skin surface 10 while maintaining an angle perpendicular to the length direction of the support member 1. As will be described in an embodiment, the shape of the handle 1 may be round, square, or hexagonal.

[0008] The shaving is performed on the skin surface 10 as shown in FIG.
The whiskers 11 protruding from the razor are removed by sliding the cutting edge of the safety razor, which is called a cutting action. Then, in order to improve the cutting action, it is necessary to make the skin surface 10 bend well and shave diagonally. By sharpening the blade, the beard is captured at an acute angle and cutting resistance is reduced. By shaving the beard obliquely, a shift stress is generated, cutting friction is reduced, and shaving is further improved. And
As shown in FIG. 9, a space where the skin surface 10 does not contact the blade is also referred to as a clearance angle 12 or a skin angle. Since the empty space is unstable, the blade angle stabilizer 5 is provided. And, depending on the thickness of the blade and the polishing angle, point angle 1
As 3, approximately 10 ° is suitable.

As described above, the present invention has been completed by considering that the conventional disadvantages have been solved at once, and the present invention is as follows.

The handle 1 is formed in the shape of a rod having a warp outward, and a support member 2 protruding from the tip of the handle 1 and bent inward is maintained at an angle crossing the handle 1 at right angles to the length direction thereof. The mounting member 3 is provided at the tip of the support member 2, the razor blade and the blade holder 4 for holding the blade angle stabilizing plate are attached to the mounting member 3, the center of gravity is provided at the tip, and the blade angle with respect to the skin is 10 °. Safety razor set from ° to 20 °.

2. The blade holder according to claim 1, wherein two blades, an upper blade and a lower blade, are provided in parallel between the safety rod and the blade angle stabilizing plate at an oblique angle. Safety razor.

The safety razor of the present invention is used as follows. Applying soap, cream, etc. to the face and shaving downward from above is called shave. The forward shaving is performed by holding the middle part of the handle 1 behind the thumb and the third finger, the middle finger, and the third finger, and holding the safety bar 6 on the skin surface 10 as shown in FIG.
In this state, the lower blade 8, the upper blade 7, and the blade angle stabilizing plate 5 come into contact with and are in close contact with each other. Since the center of gravity is provided at the tip, the weight is used to move the blade so as to slide. When you hold your little finger away, your wrist joints become softer, and you can shave soft, smooth, and shave parts of your face with undulations and bumps.

Shaving from the bottom to the top is called reverse shaving. Reverse shave, turn the safety razor upside down, handle 1
Holding the pen with the thumb, forefinger and middle finger in a manner to hold the pen with the back of the center part, stretch the skin with one free hand, and close the skin surface 10 as described above to raise the direction angle upward. While changing, you can shave a beard that has a complicated growth by digging it with the cutting edge and repeating it little by little. In this reverse shave, the safety razor of the present invention is further exhibited. Since the blade angle stabilizer 5 serves as the clearance angle 12, each part of the face can be used while maintaining a safe blade angle.
