[Prior art]

 1 and 2 are a bottom view and a cross-sectional view of a female razor having a trimmer blade. The razor shown in these figures has a movable blade 1B which contacts and slides on the lower surface of the fixed blade 1A. The movable blade 1B and the fixed blade 1A have a comb-shaped blade at the tip edge 1C at the tip. The hair is guided by a comb-shaped blade and is sandwiched between the movable blade 1B and the fixed blade 1A which reciprocate. The blade edges 1C of the fixed blade 1A and the movable blade 1B are as shown in the sectional view of FIG. That is, the blade edge 1C of the movable blade 1B is slightly retracted from the blade edge 1C of the fixed blade 1A. The hair K is guided and cut between the movable blade 1B and the fixed blade 1A as shown by the chain line in the figure.

The female razor shown in these figures is characterized in that the hair guided by the trimmer blade 1 can be reliably cut. However, since the trimmer blade 1 has the edge 1C formed in a comb shape, the edge may easily damage the skin of a woman. In particular, the cutting edge 1C of the trimmer blade 1 has a comb shape with a sharp tip in order to guide the bristles smoothly to the cut portion, and therefore the touch cannot be improved. Furthermore, since the movable blade 1B, which is slightly retracted from the cutting edge 1C of the fixed blade 1A, reciprocates at a high speed, so if the trimmer blade is strongly pressed against the skin and this part is pressed against the skin, the skin is damaged. Give

In order to prevent this adverse effect, as shown by the chain line in FIG. 1 and FIG. 2, there is commercially available a female razor in which a safety cover 2 is detachably attached to a trimmer blade 1. The safety cover 2 is made of transparent plastic and is formed into a tubular shape with the edge 1C of the trimmer blade 1 open. In order to guide the bristles to the trimmer blade 1, a comb portion 2A is provided in a portion covering both sides of the trimmer blade 1. The comb portion 2A has an elongated shape protruding from the edge 1C of the trimmer blade 1.

[Problems to be solved by the device]

 In the female razor of this structure, when the trimmer blade 1 is covered with the safety cover 2, the trimmer blade 1 can be prevented from directly contacting the skin. However, the razor of this structure has the drawback that the comb 2A is provided at the tip of the safety cover 2 to guide the bristles to the trimmer blade 1, so that the feel of the razor is not comfortable. This is because the tip of the comb portion 2A is sharp and this portion pierces the skin. Further, since the tip of the thinned comb portion 2A is pressed against the skin to prevent the trimmer blade 1 from coming into contact with the skin, it is necessary to project the comb portion 2A for a relatively long time, and there is a drawback that hair cannot be cut short. is there. In particular, the tip of the comb portion 2A locally presses the skin with a thin portion, so that this bites into the skin and the tip of the trimmer blade 1 easily comes into contact with the skin. Therefore, it is necessary to lengthen the comb portion 2A to prevent the trimmer blade 1 from coming into contact with the skin. Furthermore, the razor in which the slender tapered comb portion is projected for a long time has a drawback in that the slender comb portion is easily damaged and lacks in durability.

The present invention was developed for the purpose of solving this drawback. An important objective of this idea is to provide a female razor with a trimmer blade that can protect the skin safely and that is comfortable to the touch and cuts short hairs.

[0007]

[Means for Solving the Problems]

 The razor of the present invention has the following configuration in order to achieve the above object. The razor for women is provided with a trimmer blade 1 for cutting hair between a fixed blade 1A and a reciprocating movable blade 1B. A safety cover 2 is provided on the outer side of the trimmer blade 1. The safety cover 2 has a U curved portion 2B. Inside the U-curved portion 2B of the safety cover 2, the cutting edge 1C of the trimmer blade 1 is arranged. Further, the U-shaped curved portion 2B of the safety cover 2 is provided with a gap 3 for penetrating the safety cover 2 and inserting hair into the trimmer blade 1.

Further, in the razor of the present invention, preferably, the gap 3 provided in the U curved portion 2B of the safety cover 2 is used as a slit. The slit guides the bristles smoothly inside the safety cover 2. Hair that penetrates the safety cover 2 is cut by the reciprocating trimmer blade 1. The safety cover 2 of this structure has a feature that the unshaving portion of the hair can be reduced because the hair can be smoothly inserted inside. However, the razor for women of this invention does not specify the slit provided in the U-shaped curved portion 2B of the safety cover 2 as the slit. The shape of the gap can be circular, polygonal, or any other shape through hole, similar to the outer blade of a razor for men.

[0009]

[Action]

 In the razor of the present invention, a U-shaped curved portion 2B is provided on a safety cover 2 provided outside the trimmer blade 1, and the trimmer blade 1 is built inside the U-shaped curved portion 2B. Unlike the comb portion of the conventional razor safety cover 2, the U-shaped curved portion 2B of the safety cover 2 does not press a sharp tip against the skin. The portion that comes into contact with the skin is the curved U-shaped portion 2B. The U-shaped portion 2B makes contact with a long portion of the skin and has a soft feel, which makes the skin feel comfortable. Since the U-curved portion 2B does not dig into the skin like the tip of the comb portion, the blade edge 1C at the tip of the trimmer blade 1 can approach the inside of the U-curved portion 2B. This is because it is possible to reliably prevent the edge 1C of the trimmer blade 1 from coming into contact with the skin. Therefore, the U curved portion 2B and the cutting edge 1C of the trimmer blade 1 can be brought close to each other to cut hair shortly.

FIG. 3 is an exploded perspective view of a female razor having a trimmer blade 1. This figure is a view showing a part of the trimmer blade 1. The razor for women of the present invention is characterized in that the portion to which the safety cover is attached has a unique structure. The mechanism for reciprocating the movable blade of the trimmer blade uses, for example, a mechanism for converting the rotational movement of the motor into reciprocating movement. This mechanism connects an oscillator that converts rotational motion to reciprocating motion via an eccentric shaft that is fixed to the rotating shaft of a motor, and connects a movable blade of a trimmer blade to this oscillator for reciprocating motion.

In the female razor shown in this figure, a trimmer blade 1, a safety cover 2 and a case 5 are fixed on a base 4 in order. The trimmer blade 1 is composed of a fixed blade 1A and a movable blade 1B. The fixed blade 1A is fixed to the base 4 so as not to vibrate. Therefore, as shown in FIG. 1, the fixed blade 1A penetrates through the fixing hole 7 into which the pin 6 protruding from the base 4 is inserted. The movable blade 1B is connected to the base 4 so that it can reciprocate. Therefore, the movable blade 1B is provided with an elongated hole 8 through which the pin 6 is inserted so that the movable blade 1B can reciprocate laterally with the pin 6 protruding from the base 4 as a guide. The long hole 8 is extended in the vibration direction of the movable blade 1B. Further, the movable blade 1B has a convex portion 9 on the rear side, and the convex portion 9 is connected to a reciprocating oscillator (not shown) to be reciprocated. Further, the movable blade 1B is elastically pressed against the lower surface of the fixed blade 1A by the leaf spring 10 so that the movable blade 1B comes into close contact with and slides on the lower surface of the fixed blade 1A.

The leaf spring 10 is formed by cutting an elastically deformable metal plate into an H shape, and has four corners gently bent upward. A through hole 11 to be inserted into the pin 6 of the base 4 is provided in the center. The leaf spring 10 is arranged between the movable blade 1B and the base 4, and pushes the movable blade 1B upward to elastically press the movable blade 1B against the lower surface of the fixed blade 1A.

A safety cover 2 is arranged above the trimmer blade 1. The safety cover 2 has a U-shaped portion 2B with its tip portion curved. On the U-curved portion 2B of the safety cover 2, a cutting edge 1C of the trimmer blade 1 is arranged, as shown in the sectional view of FIG. The safety cover 2 is made of a metal plate such as stainless steel. As shown in FIG. 5, the U-shaped curved portion 2B of the safety cover 2 has a slit-shaped gap 3 for inserting hair into the trimmer blade 1. The U-shaped curved portion 2B provided with the slit is connected by the tip edge 2C thereof, and the tip edge 2C is bent inward for curling. The curled U-shaped curved portion 2B has a front edge 2C that is strongly reinforced and has a feature that the user feels comfortable when touching the skin and that the skin is prevented from being damaged.

In the safety cover 2 shown in FIG. 5, the pitch (P1) of the slits provided in the U curved portion 2B is the same as the pitch (P2) of the comb blades of the fixed blade 1A. The safety cover 2 is provided with a curved muscular bone 12 between slits opened in the U curved portion 2B. The safety cover 2 that makes the pitch of the slits the same as the pitch of the comb blade of the fixed blade 1A positions the tip of the comb blade of the fixed blade 1A on the back surface of the muscle 12. The safety cover 2 of this structure allows the bristles to pass through the slits to be efficiently guided to the trimmer blade 1, and even when the tip of the fixed blade 1A comes very close to the safety cover 2, the fixed blade 1A comb blade It has the feature that it can effectively prevent the tip from hitting the skin.

However, if the tip of the fixed blade 1A is slightly separated from the U-shaped portion 2B, the tip of the fixed blade does not necessarily have to be located on the back surface of the muscular bone 12. This is because it is possible to effectively prevent the U-shaped portion from coming into contact with the skin over a wide area and entering the inside of the slit.

In order to fix the safety cover 2 at a fixed position on the base 4, the safety cover 2 also has a through hole 13 through which the pin 6 of the base 4 is inserted. The safety cover 2 is arranged at a fixed position on the fixed blade 1A by inserting the through hole 13 into the pin 6 of the base 4. In the razor of the structure shown in FIG. 3, the leaf spring 10, the movable blade 1B, the fixed blade 1A, and the safety cover 2 are sequentially inserted into the pin 6 of the base 4 and arranged at these fixed positions. The case 5 is fixed on the upper end, and these parts are mounted in place. In this state, the movable blade 1B is reciprocated to cut the hair that has passed through the slit of the safety cover 2 with the trimmer blade 1.

In the razor having the above structure, the gap of the safety cover that guides the bristles to the inside is a slit. The slit can effectively guide the hair inside. However, the razor of this invention does not specify the gap as a slit. The gap may be of any shape capable of guiding the bristles inside, for example circular, elliptical or polygonal.
