When shaving the face or the like with a Japanese-style razor as in Non-Patent Document 1, it is dangerous to apply force to the hands, so barbers and the like shave while adjusting the force. However, when using such a Japanese-style razor, it is common for barbers and others to shave with the index finger or middle finger floating in order to relax. For people with small hands, such as shaving, the operation is very difficult, and long experience and training are required to shave well and safely. In addition, recently, for example, women's face (downy hair) is frequently shaved before a wedding ceremony, and in this case, it is necessary to perform a softer shaving method.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to safely and smoothly shave hair even for users with small hands or inexperienced barbers. 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 to which a user attaches a hand, the handle comprising: The handle has a circular, elliptical, or polygonal shape in a cross-section perpendicular to the axial direction of the handle, and includes a trunk and a first constricted portion positioned closer to the blade than the trunk.

As shown in FIG. 2( a ), the handle 11 has a first constricted portion 12 , a trunk portion 13 and an end portion 14 . The handle 11 has a polygonal shape on a cross section orthogonal to the axial direction of the axis O, and has a wavy contour in plan view. Although the cut surface of the handle 11 is hexagonal in FIG. 2B, it may be polygonal, for example, quadrangular, octagonal, or hexagonal. Also, it may not be a regular polygon and may have rounded corners.

FIG. 3 is a plan view of a razor handle according to a third embodiment of the present invention; As shown in FIG. 3 , the handle 21 has a first constricted portion 22 , a trunk portion 23 , an end portion 24 and a second constricted portion 25 . Materials for the handle 21 include metal, resin, and wood.

The second constricted portion 25 is provided closer to the end portion 24 than the trunk portion 23 . Therefore, in the present embodiment, the shape is such that the portion from the second constricted portion 25 to the end portion 24 is swollen.

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 razor using the razor handle according to the first embodiment of the present invention It is a top view which shows an example of a razor. As shown in FIGS. 4 and 5, the razor R1 includes a handle 1 and a blade body 6. As shown in FIGS.

The blade body 6 is generally used for shaving in a barber shop or 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 manner in which the blade body 6a and the handle 1 are connected by the connecting portion 6b is not particularly limited as long as it does not affect the shaving operation.

FIG. 6 is a front view showing an example of a razor using the razor handle according to the third embodiment of the present invention, and FIG. It is a top view which shows an example of a razor. As shown in FIGS. 6 and 7, the razor R2 includes a handle 21 and a blade body 6. As shown in FIGS.

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

The handle 101 is curved so as to expand downward. The handle 101 has a rectangular shape or a square shape with rounded corners on a cross section orthogonal 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 a razor handle according to the first embodiment of the present invention. As shown in FIG. 10, the razor R3 has a handle 1 and a blade 26. As shown in FIG. The method of connecting the handle 1 and the blade 26 is not particularly limited, but for example, it may be directly inserted into the handle 1, or a connecting member may be provided on the opposite side of the end 4 of the handle 1 and the blade 26 attached thereto. may be connected.

In FIG. 10, the blade body 26 has both an upper blade portion 26a and a lower blade portion 26b, but as another embodiment, only one of them may be provided. The upper blade portion 26a and the lower blade portion 26b are shaving razor cartridges, and normally the same member is used, but different members may be used depending on the application and the shaved area.

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 a 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. 11( a ) and 11 ( b ), the handle 31 has a plurality of grooves 37 extending parallel to the axial direction of the handle 31 . Materials 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 are oriented outward, but when the hand is closed, the fingertips are oriented inward. Therefore, when grasping an object with the hand, it is better to prepare the surface of the object along this arrangement of the fingertips, which is particularly important with a razor for hairdressing, in which too much force must not be applied during shaving.

FIG. 13 is (a) a schematic diagram showing one example and (b) a schematic diagram showing another example of how to hold a conventional razor. As shown in FIG. 13(a), as an example of how to hold a conventional razor, first, hold the vicinity of the connecting portion between the connecting portion 102b and the handle 101 so as to pinch with the thumb and forefinger. Furthermore, the end side of the handle 101 is sandwiched between the back of the fifth middle phalanx of the little finger and the pad of the fourth distal phalanx of the ring finger. The middle finger does not touch the razor 100 and is in a floating state. If the hand holding the razor is too strong, the skin may be damaged during shaving, which is extremely dangerous. However, as described above, the middle finger must be held in a floating manner, and especially for women with small hands, the way of holding becomes unstable and shaving becomes difficult. In addition, as shown in FIG. 13(b), when a conventional razor is rotated 90 degrees from the state of (a) with the longitudinal direction as an axis to hold the handle, the middle finger should also be placed along the handle. Then, when the hand is closed as shown in FIG. It becomes difficult to put in. Therefore, in the case of the conventional razor R0, it takes a very long time, for example several years to five years, until shaving can be performed without 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, the handle 1 is held by the first constricted portion 2 so as to be pinched between the thumb and index finger. Further, the middle finger is lightly placed on the trunk 3. Then, the portion closer to the end portion 4 than the trunk portion 3 is sandwiched between the back of the fifth middle phalanx of the little finger and the pad of the fourth distal phalanx of the ring finger. In this embodiment, as shown in FIG. 12(b), when the hand is closed, the fingertips are directed toward the inside, so that the barber or the like can hold the razor without exerting force, and the razor does not slip. You can shave easily and safely. Moreover, even if the part holding the handle is changed according to the size of the hand, the razor can be stably held, and even a person with small hands such as a woman can stably hold the razor. Therefore, even a person who has just become a barber can shave hair in a short period of time. Furthermore, even in shaving lanugo hair, especially for women before marriage, which is often practiced these days, shaving can be safely and effectively performed without damaging the skin of the woman. Also, general consumers can use the razor according to the embodiment for shaving their own hair at home, for example.

FIG. 15 is a schematic diagram showing another example of how to hold the razor using the razor handle according to the first embodiment of the present invention. Also in this case, the handle 1 is held by the first constricted portion 2 so as to be pinched between the thumb and index finger in the same manner as shown in FIG. Further, the middle finger is lightly placed on the trunk 3. Then, the portion closer to the end portion 4 than the trunk portion 3 is sandwiched between the back of the fifth middle phalanx of the little finger and the pad of the fourth distal phalanx of the ring finger. In addition to being non-slip, the razor for this embodiment provides a more natural shave because the blade body 26 includes an upper blade portion 26a and a lower blade portion 26b, which are shaving razor cartridges. This makes it easy for not only professionals such as barbers but also general consumers to use it. Also, the razor according to the present embodiment can be used by both right-handed and left-handed people.

Also, in the embodiment shown in FIGS. 14 and 15, when the handle 21 shown in FIG. 3 is used, the ring finger and little finger can be more stably and safely supported by the second constricted portion 25 and the end portion 24. When the handle 31 shown in FIG. 11 is used, even if soap or the like gets on the hand or the handle, the grooves 37 make it more difficult to slip, and safe shaving can be performed.

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