Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a razor, and more particularly to a manual safety razor.

[0002]

2. Description of the Related Art Conventionally, a razor is classified into a manual type and an electric type. Western type knife-type razors and T-shaped razors are commercially available as manual types. In such a manual razor, an attempt has been made to improve the shaving ability by using a plurality of blades as seen in a two-blade, a three-blade or the like.

[0003]

However, an increase in the number of blades means that the number of times of rubbing the skin in one operation is two.
The tendency to damage the skin is increased by increasing the number of times. Even if a single blade is used, the blade must be pressed against the skin in order to shave the hair, and the skin must be shaved at the same time. After shaving, the skin irritates and sometimes bleeds.

[0004] Specifically, when shaving, the blade presses the skin, so that the skin is dented. This means that soft skin is pressed with a sharp blade, and it is natural that the skin is shaved. A more serious problem is that the hair is laid down by holding down the skin with the blade, making it difficult to shave. Because it is difficult to shave, the blade is pressed more firmly on the skin, causing a vicious cycle on the skin.

[0005] When the blade is slid on the skin in a direction parallel to the blade tip line, the skin is cut and bleeding, sometimes leading to a serious accident. Therefore, in order to improve safety, when a thin metal thread is wound around the blade and the blade moves in the direction parallel to the blade tip line,
Some are designed to make the skin harder to cut. In this case, although the safety is slightly improved, the effect is small, while the shaving property is reduced.

[0006] It is an object of the present invention to provide a razor which can be used safely by adults, children and women without improving the safety and shaving properties and without damaging the skin.

[0007]

In order to solve the above-mentioned problems, a razor according to the present invention comprises a razor having a first blade and a second blade which are separated by a predetermined distance. Alternatively, they are configured to face each other to perform a shaving action, and when the first blade moves in the shaving direction, the second blade precedes the first blade without performing the shaving action. When the second blade moves in the shaving direction while contacting the shaved portion, the first blade contacts the shaved portion prior to the second blade without performing a shaving action, and Also in the shaving direction, the shaving target enters here, with the space where the first and second blades face each other as a common space.

As described above, the razor of the present invention is provided with the first blade and the second blade, and each blade edge is opposed to each other in order to make the shaving directions different from each other. A predetermined interval is formed between the blades, and a shaving target such as a hair, a beard, or the like inserted in the interval can be shaved in any shaving direction. Efficiency in shaving, for example, which relatively represents how much hair can be shaved in one razor movement) is very high. In addition, when one blade moves in the shaving direction, the other blade comes into contact with the shaved part in advance without performing a shaving action, so that it is possible to prevent or suppress at least the blade edge from contacting the skin. Becomes less likely to damage the skin. Furthermore, since the blade that comes in contact in advance (specifically, the back surface of the blade comes into contact) can press the skin to make the beard stand, the shaving efficiency can be further improved.

[0009] In the above configuration, in the first blade and the second blade, the back surface of each blade may have the same tangent line, or the back surface of each blade may have a surface in common contact. Can be In this case, even when the razor is moved in any of the shaving directions, the cutting edge does not hit the shaved portion at an acute angle, and moves on the shaved portion while maintaining a contact state, so that the skin is not easily damaged. .

[0010] More specifically, as a first aspect of the razor, the first blade and the second blade are formed on one side of different plate-like members, respectively. With the configuration in which the blade edges of the second blade face each other, each plate-shaped member can be held by the holding member. In this case, each plate-like member is detachably held to the holding member, and the holding member is formed in a form in which plate-like member grippers capable of holding the plate-like member face each other,
Each of the plate members may be detachably attached to the grip portion.

As described above, the first blade and the second blade are formed of different plate-like members, and each plate-like member is detachably held to the holding member, thereby providing a blade (plate-like member). Can be replaced arbitrarily, and when the blade is worn out, it can be replaced and the plate member can be disposable. The attachment and detachment of the plate member can be performed by inserting and removing the plate member into an insertion portion such as a groove formed in the holding member.

On the other hand, as a second aspect of the razor, the first blade and the second blade are formed on mutually opposite sides of the same plate-like member, and the plate-like member warps. Thereby, the first blade and the second blade can be configured to face each other. In this case, the razor of the present invention can be easily configured simply by warping one plate-shaped member. In addition, the back surface of each blade is formed by a warped convex surface, and the convex surface comes into contact with the shaved portion in advance, so that it is possible to smoothly slide on the shaved portion and the skin is less likely to be damaged.

The warped plate-shaped member is detachably held by a holding member having at least a cylindrical portion having a cylindrical shape, and the cylindrical portion has a predetermined notch formed therein. The first and second blades may project into a space formed by the notch. In this case, the first blade and the second blade are formed of the same plate-like member, and the plate-like member is detachably held to the holding member, thereby replacing the blade (plate-like member). Can be performed arbitrarily, and can be replaced when the blade is worn out, and the plate member can be disposable. In this case as well, the attachment and detachment of the plate-like member can be performed by inserting and removing the plate-like member into an insertion portion such as a groove formed in the holding member.

Further, the razor of the present invention is constituted by a cylindrical member, and a predetermined notch is formed in a longitudinal direction of the cylindrical member, and the notch is formed in two notch surfaces formed in the longitudinal direction. The first blade and the second blade may be formed. In this case, the back surface of each blade is formed by the convex curved surface of the cylinder, and the convex curved surface comes into contact with the shaved portion first, so that the razor can be smoothly slid over the shaved portion. That is, since the skin and the blade are in surface contact, the skin is smooth and safe, and the shaving of the skin is prevented or suppressed, so that no pain is felt even when shaving. In addition, it becomes possible to press the skin and cause the beard or the like to be shaved to stand up before the subsequent first or second blade in which the convex curved surface is mainly shaved, and the standing beard can be effectively deepened. It is possible to shave off.

The notch of the tubular member is formed in a spiral shape in the longitudinal direction along the circumferential surface of the tubular member, and the first blade and the second blade are formed in a spiral shape. May be provided along. By forming each blade in a spiral shape, the object to be shaved can be shaved regardless of the direction in which the cylindrical member is moved. Preferably, the lead angle of the spiral is 45 ° or less, or a double spiral or the like. It is good to form with.

Next, in a different embodiment of the razor of the present invention, the cylindrical member is notched in its longitudinal direction, or the substantially cylindrical member is notched obliquely along the peripheral surface thereof, or the cylindrical member is notched. Notched spirally along the peripheral surface, and those notched 2
The first surface and the second blade are formed by processing each of the two surfaces into a blade shape so as to be able to shave the object to be shaved, and the cutting edge of the first blade and the cutting edge of the second blade are formed. With the cutting edge,
The first blade is configured to face each other so as to alternatively perform a shaving action at a predetermined interval, and when the first blade moves in the shaving direction, the second blade does not perform the shaving action. The second blade contacts the shaved portion prior to the first blade;
When the first blade moves in the shaving direction, the first blade contacts the shaved portion prior to the second blade without performing a shaving action, and in any shaving direction,
The distance at which the second blade is opposed is set as a common distance, and the object to be shaved enters here.

As described above, the cylindrical member is cut in the longitudinal direction, the substantially cylindrical member is cut obliquely along the peripheral surface, or the cylindrical member is cut spirally along the peripheral surface. By machining the two missing surfaces into blade-like shapes so that the shaving target can be shaved, it is possible to easily obtain the series of first blades and second blades described above. is there.

In the case where the convex surface such as the cylindrical member and the warped structure comes in contact with the shaved portion, it is possible to shave without looking at the mirror for safety, and the invisible portion such as the back of the neck can be removed. It is possible to shave. In addition, not only women who are not used to razors and elderly people, but also those who are handicapped or blind can use it with peace of mind. Also, it can be used in beauty salons etc. who feel resistance to razors,
Because the blade is not exposed, it is safe and secure when carrying.
