When shaving the face or the like with a Japanese-style razor such as the one disclosed in Non-Patent Document 1, it is dangerous to use too much force in the hands, so barbers and the like adjust the amount of force they use while shaving. However, when holding such a Japanese-style razor, it is common for barbers to lift their index or middle fingers while shaving to relieve pressure, which makes it difficult to hold and apply force, especially for women. This task is extremely difficult for people with small hands, and long experience and training are required to shave successfully and safely. Furthermore, recently, for example, women often shave their faces (downy hair) before a wedding ceremony, and in this case, it is necessary to shave in a softer manner.

The present invention was made to solve the above problems, and its purpose is to enable users with small hands or inexperienced barbers to shave hair safely and smoothly. It is something to do.

A razor handle according to one aspect of the present invention is a razor handle for use in a razor having a blade body having a blade portion and a handle on which a user places a hand, the handle being The blade has a circular, elliptical, or polygonal shape in a cut plane perpendicular to the axial direction of the handle, and includes a body portion and a first constriction portion located closer to the blade body than the body portion.

According to the razor handle of the present invention, even users with small hands or inexperienced barbers can shave safely and smoothly.

The second constricted portion 25 is provided closer to the end portion 24 than the body portion 23 . Therefore, in this embodiment, the shape is bulged from the second constricted portion 25 to the end portion 24.

FIG. 4 is a front view showing an example of a razor using the razor handle according to the first embodiment of the present invention, and FIG. 5 is a front view showing an example of a razor using the razor handle according to the first embodiment of the present invention. FIG. 2 is a plan view showing an example of a razor. As shown in FIGS. 4 and 5, the razor R1 includes a handle 1 and a blade 6. As shown in FIGS.

The blade body 6 is commonly used for shaving in barbershops and the like, and includes a blade portion 6a and a connecting portion 6b. Examples of the material of the blade body 6 include metal. The mode of connection between the blade body 6a and the handle 1 through the connection portion 6b is not particularly limited as long as it does not affect the shaving operation.

FIG. 2 is a plan view showing an example of a razor. As shown in FIGS. 6 and 7, the razor R2 includes a handle 21 and a blade 6. As shown in FIGS.

FIG. 8 is a front view of a conventional razor, and FIG. 9 is a plan view of a conventional razor. The conventional razor R0 includes a handle 101 and a blade body 102.

The handle 101 is curved so as to swell downward. The handle 101 has a rectangular shape or a rounded square shape in a cut plane perpendicular to the longitudinal direction of the handle 101. The blade body 102 includes a blade portion 102a and a connecting portion 102b.

FIG. 10 is a front view showing another example of a razor using the razor handle according to the first embodiment of the present invention. As shown in FIG. 10, the razor R3 includes a handle 1 and a blade body 26. The method of connecting the handle 1 and the blade body 26 is not particularly limited, but for example, it may be inserted directly into the handle 1, or a connecting member may be provided on the side opposite to the end 4 of the handle 1, and the blade body 26 may be attached to it. May be connected.

In FIG. 10, the blade body 26 includes both an upper blade portion 26a and a lower blade portion 26b, but may include only one of them as another embodiment. The upper blade part 26a and the lower blade part 26b are a shaving razor cartridge, and usually use the same member, but different members may be used depending on the purpose and the area to be shaved.

FIG. 11 is (a) a front view and (b) an enlarged view of the vicinity of the end of the handle regarding still another example of a razor using the razor handle according to the fourth embodiment of the present invention. As shown in FIG. 11(a), the razor R4 includes a handle 31 and a blade body 26. As shown in FIG.

As shown in FIGS. 11A and 11B, the handle 31 has a plurality of grooves 37 extending parallel to the axial direction of the handle 31. As shown in FIGS. Examples of the material for the handle 31 include metal, resin, and wood.

FIG. 12 is a schematic diagram showing the orientation of the tips of the fingers with respect to (a) when the hand is open and (b) when the hand is closed. When the human hand is open, the fingertips point outward and away from each other, but when the hand is closed, the fingertips point inward. Therefore, when grasping an object with your hand, it is better to create the surface of the object in accordance with the arrangement of the fingertips, which is especially important with a barber's razor where you must not apply much force when shaving.

FIG. 13 is a schematic diagram showing (a) one example of a conventional way of holding a razor, and (b) a schematic diagram showing another example. As shown in FIG. 13(a), as an example of how to hold a conventional razor, first, hold the area near the connecting portion 102b and handle 101 so as to pinch it between your thumb and index finger. Furthermore, the end side of the handle 101 is held between the dorsum of the fifth middle phalanx of the little finger and the pad of the fourth terminal phalanx of the ring finger. The middle finger is not touching the razor 100 and is in a floating state. If you hold a razor with too much force, it can damage your skin when shaving, which is very dangerous, so barbers and the like need to hold the razor without using too much force. However, as mentioned above, the user must hold the device with the middle finger in the air, making the device unstable to hold and shaving difficult, especially for people with small hands, such as women. Further, as shown in FIG. 13(b), when holding the handle of a conventional razor by rotating it 90 degrees from the state of (a) with the longitudinal direction as the axis, the middle finger should also be able to follow the handle. In this case, when the hand is closed, as shown in Figure 12(b), all the fingertips except the little finger will be placed on the flat surface of the handle, and the amount of force applied will be unnatural and the force applied during shaving will be unnatural. It becomes difficult to insert. Therefore, in the case of the conventional razor R0, it takes a very long time, for example, several to five years, until the user can shave without any problems.

FIG. 14 is a schematic diagram showing an example of how to hold a razor using the razor handle according to the first embodiment of the present invention. First, hold the first constriction part 2 of the handle 1 by pinching it between your thumb and forefinger. Furthermore, lightly touch the body part 3 with your middle finger. Then, the portion closer to the end portion 4 than the body portion 3 is sandwiched between the dorsum of the fifth middle phalanx of the little finger and the pad of the fourth terminal phalanx of the ring finger. In this embodiment, the fingertips are oriented inward when the hand is closed as shown in FIG. You can shave easily and safely. In addition, even if you change the handle to match the size of your hand, you can stably hold the razor, and even people with small hands, such as women, can hold the razor stably. Therefore, even a person who has just become a barber can shave hair in a short period of time. Furthermore, even in the case of shaving women's downy hair, which has recently become common practice, especially for women before marriage, it is possible to safely and effectively shave women's hair without damaging their skin. Furthermore, it becomes possible for general users to use the razor according to the embodiment at home, for example, for shaving their own hair.

FIG. 15 is a schematic diagram showing another example of how to hold a razor using the razor handle according to the first embodiment of the present invention. In this case as well, the handle 1 is held with the first constricted portion 2 so as to be pinched between the thumb and index finger in the same manner as shown in FIG. Furthermore, lightly touch the body part 3 with your middle finger. Then, the portion closer to the end portion 4 than the body portion 3 is sandwiched between the dorsum of the fifth middle phalanx of the little finger and the pad of the fourth terminal phalanx of the ring finger. In the case of the razor according to this embodiment, in addition to being hard to slip, the blade body 26 includes an upper blade part 26a and a lower blade part 26b, and since these are a razor cartridge for shaving, it is possible to shave more naturally. This makes it easy to use not only by professionals such as barbers but also by general consumers. Furthermore, the razor according to this embodiment can be used by both right-handed and left-handed people.

Furthermore, in the embodiment shown in FIGS. 14 and 15, when the handle 21 shown in FIG. When the handle 31 shown in FIG. 11 is used, even if soap or the like gets on the hands or the handle, the grooves 37 make it more difficult to slip, allowing safe shaving.

The embodiments disclosed this time should be considered to be illustrative in all respects and not restrictive. The scope of the present invention is indicated by the claims rather than the above description, and it is intended that all changes within the meaning and range equivalent to the claims are included.
