Description

  The present invention relates to a haircut razor for partially cutting hair and a haircut replacement razor used for a haircut razor.

The use of razors for haircuts has been widely used for the purpose of hair cosmetics.
For example, the invention of the form described in JP2003-190675A is known.
In this example, the blade body 32 of the razor 30 is covered with a semicircular protrusion 36 protruding from the blade edge 34 so that the blade edge 34 is intermittently covered, and the exposed blade edge 34a and the coated blade edge 34b are alternately arranged. Is provided.
A groove 38 is provided between the adjacent pair of protrusions 36, 36 for the purpose of limiting the amount of hair to be cut when cutting the hair (see FIGS. 16 and 17).
JP 2003-190675 A

However, in the above-described background art, the amount of hair supplied to the exposed blade edge 34a of the blade body 32 at the time of cutting the hair can be evaluated for the advantage of being stabilized by the protrusion 36, but it is exposed to the hair. The blade edge 34a faces a right angle (cross-shaped) like a known razor of this kind (see FIGS. 18 and 19).
Therefore, although moving the razor 30 along the scalp of the head T does not deny that the hair H can be cut reliably, there is a problem in the following points.
Since the blade edge 34a exposed to the hair H faces a right angle, the possibility of excessively cutting the hair H could not be avoided.
This point will be further described with reference to FIGS. 16 to 19. Since the blade edge 34 a of the blade body 32 moves in a direction perpendicular to the hair H as shown in the figure, the hair H is reliably cut. Although the cutting function improves as the angle of inclination of the blade edge 34a increases from the acute angle to the right angle with respect to the hair H, the hair H tends to be excessively cut as the cutting function is improved, and the cutting is not performed. There is a risk that a so-called “tiger cutting phenomenon” may occur due to a difference between the hair part of the hair part and the hair part of the cut part.
On the other hand, in order to avoid the tiger-cutting phenomenon of the hair H, even if an attempt is made to change the inclination angle of the blade edge 34a in order to suppress excessive hair cutting, the operation is not always easy.
When cutting the hair H of the head with the razor 30 by itself, the hair H on the back of the head, which is difficult to see, is taken into account, and the so-called “hanging” is performed. There is a possibility that the amount of hair cut will be too small or, conversely, the amount of hair cut may be small.
In order to avoid this tiger cutting phenomenon, it is necessary to adjust the contact angle of the blade edge 34a of the razor 30 with respect to the hair H appropriately.
However, setting the inclination angle of the blade edge 34a of the razor 30 to be constant, and maintaining the angle while continuously cutting the hair H is extremely difficult due to the nature of manual operation. It was difficult to adjust the balanced hair H.
The object of the present invention is to solve the problems of the background art configuration described above, without excessively cutting the hair and vice versa. In particular, it is to provide a haircut razor that does not cause the tiger-cutting phenomenon, and to provide a haircut replacement razor for use in the haircut razor.
Another object of the present invention is to provide a haircut razor and a haircut replacement razor that are highly safe and do not cause damage to human fingers or the like due to a knife when handling the haircut razor and haircut replacement razor. It is in.

Effects Since the first problem solving means is configured as described above, the following effects can be obtained.
The blade side of the haircut razor is directed toward the hair and is generally moved from the top side of the head to the neck side along the scalp.
In this case, the cutting edge of the blade does not touch the hair at a right angle as in the background art, and the cutting edge moves while rubbing the hair. For example, it is cut obliquely from the cutting start portion to the cutting end portion (see FIG. 6).
In this invention, by moving the razor, the cutting edge of the blade is directed downward following the length direction of the hair, and the hair is gradually cut along with the movement of the cutting edge so as to rub or scrape the hair. (See FIGS. 4, 5, and 6).
In this case, since the cutting edge of the blade is cut while being in contact with the hair, the amount of hair cut gradually decreases from the head side to the neck side.
This means that when hair is focused on the fact that the hair root side is generally thicker and gradually narrows toward the hair tip side, the hair is simulated as a natural hair and does not cause so-called tiger cutting (FIGS. 4 and 4). 5, see FIG.
Since the second problem solving means is configured as described above, it has the following effects in addition to the same effects as the first problem solving means.
When cutting the hair on the back side of the head, generally hold the hair-cut razor in the right hand and move the hair-cut razor from the right side of the back side of the head to the left side of the neck, and vice versa. The razor is moved to draw a circle from the left side of the back side of the head to the right side of the neck side.
In these cases, it is desired that the cutting edge of the blade is directed in the moving direction.
However, in order to satisfy the hope, it is necessary to produce the razor separately for the right hand and the left hand. However, it is cumbersome to produce both separately and the production cost increases. Therefore, this inventor can use both the left and right sides by arranging the cutting edges of the blades in different directions as described above.
Since the third problem solving means is configured as described above, the following effects can be obtained.
In addition to the operational effects exhibited by the first or second problem solving means, the cutting edge is inclined with the reference line of the hair-cut razor base material as a ridge, which further contributes to the improvement of the hair cutting function.
That is, the hair is cut along the spherical scalp of the human body. In this case, the cutting edge of the blade moves with a certain range of angle so as to draw an arc.
Therefore, since the cutting edge is inclined in accordance with the angle at the time of movement, a cutting angle close to ideal can be obtained, so that more preferable hair cutting can be performed.
Since the 4th problem-solving means is comprised as mentioned above, there exist the following effects.
In addition to having the same effects as the second problem solving means, since the blades are arranged in non-parallel, especially in the case of short hair, for example, in the case of male hair, the hair is in a protruding state. Since it is easily caught by the blade edge of the blade, it contributes to cutting short hair.
Since the fifth problem solving means is configured as described above, the following effects can be obtained.
In addition to having the same effects as the first problem solving means, the cutting edges of the blades are arranged in the same direction, and the blades are arranged in parallel, so further improvement of the cutting function is expected. it can.
Since the sixth problem solving means is configured as described above, the following effects can be obtained.
In addition to the operational effects of the first, second, third, fourth, or fifth problem solving means, a control member that suppresses injury when handling a haircut razor is provided beside the cutting edge. There is no risk of injury.
Since the seventh problem-solving means is configured as described above, the following effects can be obtained.
In addition to the functions and effects of the first, second, third, fourth, fifth or sixth problem solving means, the control member also serves as a bristle, so that the hair is combed while cutting the hair with the blade and the bristle. It can be performed.
Since the eighth problem-solving means is configured as described above, the following effects can be obtained.
Since this haircut replacement razor is attached to the haircut razor body, the same effect as the first problem solving means can be obtained, and the haircut replacement razor can be replaced in preparation for the deterioration of the razor. A hair-cut razor with good sharpness can be easily obtained at any time.
Since the ninth problem-solving means is configured as described above, it has the following effects.
The effects common to the second and eighth problem solving means can be obtained.
Since the tenth problem solving means is configured as described above, the following effects can be obtained.
The effects common to the third and eighth problem solving means can be obtained.
Since the eleventh problem solving means is configured as described above, the following effects are obtained.
The effects common to the fourth and eighth problem solving means can be obtained.
Since the twelfth problem solving means is configured as described above, the following effects are obtained.
The effects common to the fifth and eighth problem solving means can be obtained.
Since the thirteenth problem solving means is configured as described above, the following effects are obtained.
The effects common to the sixth and eighth problem solving means can be obtained.
The fourteenth problem solving means has the above-described configuration, and therefore has the following effects.
The effects common to the seventh and eighth problem solving means can be obtained.
According to the fifteenth problem solving means, by integrating the haircut razor tool of the present invention with a hair brush, it is possible to obtain an effect that a desired haircut can be performed simultaneously with the brushing operation.
The sixteenth problem solving means basically obtains the same function and effect as the fifteenth problem solving means, but the hair cutting operation is performed by providing a difference in bristle density before and after the blade edge in a certain direction. It is possible to obtain an effect that it becomes possible to perform the operation more smoothly.
The seventeenth problem-solving means obtains an effect that the hair cutting operation can be performed smoothly and the finished state of the brushing can be improved by making the bristle density on the front side of the blade edge smaller than that on the rear side. be able to.
The eighteenth problem-solving means is that when the haircut razor tool of the present invention is integrated with a hairbrush, even if the sharpness of the cutting edge becomes dull, it is easily replaced to ensure the necessary sharpness. The effect of being able to continue can be obtained.

  The invention of haircut razor 10 and haircut replacement razor 20 according to an embodiment of the present invention will be described with reference to the drawings.

The haircut razor 10 of Embodiment 1 is demonstrated.
In this example, a cutting tool 12 having a cutting edge 12a is fixed on a razor base material 14 for hair cutting, the cutting tools 12 are arranged in parallel, and the cutting edges 12a of the five cutting tools 12 are in the same direction. This is an example in which the upper blade edge 12a is directed to the left side (see FIG. 1). Although the details will be further described later, the example shown in FIG. 1 is a preferable example in the case of cutting the hair from the right side to the neck side on the back surface of the hair of the scalp of the head T, which can be said to be for the right hand. .
On the other hand, the example shown in FIG. 2 can be said to be for the left hand in which the cutting edge 12a is directed to the right side in the drawing in contrast to the example of FIG.
These examples are basically based on the fact that the blade 12 provided with the blade edge 12a is erected on the razor base material 14 for haircut, and the blade edge 12a is arranged in a direction perpendicular to the rising direction of the blade 12. It is a typical structure.
Although it is common in this type of razor 10 to provide a handle 16 at one end of a haircut razor base material 14, the handle 16 is merely a convenience in use and is essential in the present invention. is not.
Although the number of the blades 12 provided with the cutting edges 12a is basically one, it is generally preferable that two or more, for example, about five as shown in FIGS. 1 and 2 are raised. .
The specific configuration of the blade 12 will be further described with reference to FIG. 3. A rectangular thin plate-shaped blade 12 is placed in a plastic blade cover 12b having a substantially U-shaped cross section, and the blade edge 12a is placed on the open side of the cover 12b. The interior is exposed.
Since the blade 12 is made of metal as is generally known, when cutting the hair of the scalp, attention must be paid to controlling the danger.
Therefore, in the present invention, most of the periphery of the blade 12 except for the blade edge 12a side necessary for cutting the hair is used for the above-mentioned blade so that the blade 12 does not get injured by being in contact with the scalp of the human body during use. It is covered with a cover 12b and a haircut razor base material 14.
In addition, as described above, the blade 12 is generally a thin plate-shaped member, and it cannot be denied that the blade 12 lacks strength. Therefore, the strength of the blade 12 can be increased by installing the blade 12 in the blade cover 12b. It is also intended.
Furthermore, when plastics is employed for the blade cover 12b, the material can advantageously contribute to avoiding injury to the scalp when the razor 10 is used.
As shown in FIG. 3, the cover 12b of the blade 12 has projections 12c slightly protruding beyond the extension line of the blade edge 12a in a direction perpendicular to the extension line of the blade edge 12a of the blade 12 at regular intervals. One is provided.
In addition to being able to increase the strength of the cover 12b by these projections 12c, by providing the projections 12c at regular intervals, the hair H introduced between the adjacent blades 12 at the time of cutting is divided by the projections 12c. it can.
Therefore, since the hair H is not concentrated on the local part of the blade edge 12a, no concentrated stress is exerted on the blade edge 12a, so that the hair H can be cut smoothly and no load is applied to the blade edge 12a.
A pin-like member that is raised beside the blade edge 12a of the blade 12 is a control member 18 that protects the fingertip of the human body when the razor 10 is handled.
The position of the control member 18 is preferably deviated from the center line of the blade edge 12a to the left and right by, for example, about 5 mm so as not to damage the hair H introduced into the blade edge 12a when the hair H is cut.
The effect of the first embodiment of the present invention will be described (see FIGS. 4, 5, and 6).
The blade 12 side of the haircut razor 10 is directed toward the hair H and is generally moved from the top of the head to the neck side along the scalp T.
In this case, the cutting edge 12a of the blade 12 does not contact the hair H in a direction perpendicular to the hair H as in the background art, and the cutting edge 12a moves so as to rub the hair H along the hair H.
This point will be described in more detail. By moving the razor 10, the cutting edge 12a of the blade 12 is directed to the neck side of the human body so as to follow the length direction of the hair H, along the hair H, and The hair H is gradually cut along with the movement in the direction of the arrow Y in FIGS.
In this case, the blade edge 12a of the blade 12 moves in the acute angle direction without moving the blade body 32 in the direction perpendicular to the hair H as in the background art.
The cutting edge 12a moving in the acute angle direction gradually moves from the hair H positioned above the head to the hair H positioned on the neck side. In this case, the moving direction of the cutting edge 12a is relative to the hair H. Since the blade edge 12a never moves in a direction perpendicular to the hair H because it is an acute angle direction that is nearly parallel to the hair H, the hair edge 34a is different from that in which the blade edge 34a of the background art moves in a direction perpendicular to the hair. Since the hair H can be cut in a sharp manner and the tape H can be obtained, it is possible to make up the hair without any discomfort (see FIG. 6).
Therefore, since there is no difference in the cut amount between the cut portion and the non-cut portion of the hair H, the hair can be adjusted and averaged without causing tiger cutting.

A second embodiment will be described.
This form 2 is demonstrated with reference to FIG.
In this example, since there is little difference in the essence of the invention as compared with the first embodiment, a configuration that differs in principle will be referred to, and the description of the first embodiment described above will be used for the common configuration.
On the base material 14 for a haircut razor having a handle 16, six blades 12 having blade edges 12a are raised in parallel.
Although all the blade edges 12a of the blade 12 of the first embodiment are in the same direction, in this example, the blade edges 12a of the six blades 12 are arranged in different directions for each adjacent blade edge 12a as shown in the figure. ing.
The arrangement directions of these blade edges 12a differ from each other by 180 degrees in the illustrated example, but are not limited to 180 degrees.
The pin-like control member 18 is provided beside the cutting edge 12a of the blade 12 as in the first embodiment.
It can be easily understood from the description of the first embodiment that this example has an advantage that the cutting edge 12a of the blade 12 is provided in different directions, so that it can be used left and right as apparent from the above description when used. Will be done.

A third embodiment will be described.
In this example, since there is little difference in the essence of the invention as compared with the first embodiment, a configuration that differs in principle will be referred to, and the description of the first embodiment described above will be used for the common configuration.
This example will be described with reference to FIGS. 8 and 9. In the first embodiment, the blade 12 is provided in parallel without being inclined. In this embodiment, the blade edge of the blade 12 is provided. While the direction of 12a is set in the same direction, there are provided one inclined to the upper right in the drawing with respect to the reference line L and one inclined to the upper left in the drawing with respect to the reference line L. (See FIGS. 8 and 9).
Therefore, this embodiment is common to Embodiment 1 in that it is used for right hand and left hand in use.
The angle of the blade edge 12a with respect to the hair H when the haircut razor 10 is used is often different depending on the user's preference, the combing part of the hair H, and the part to be cut.
Furthermore, the angle with respect to the hair H is also expected to be different depending on the difference in dominant arm.
Therefore, the inventor tried to study the use angle experimentally in consideration of the difference in the use conditions.
As a result, for example, when the dominant arm is right-handed and the hair H of the right occipital region is moved from the right side toward the neck to move the haircut razor 10 diagonally, the hair H is combed and cut. In this case, the inclination angle of the blade edge 12a of the blade 12 is in the range of 10 to 80 degrees, preferably about 60 degrees, in the upper left of the drawing with respect to the reference line L of the haircut razor base material 14. It turned out to be appropriate (see FIG. 8).
On the other hand, the inclination angle when the dominant arm is a left-handed person and the hair H of the left occipital region is combed and cut is based on the reference line L of the base material 14 for the hair-cut razor symmetrically with the above. On the other hand, it was found that the range of 100 to 170 degrees in the upper right of the drawing, preferably 120 degrees, was appropriate (see FIG. 9).

A fourth embodiment will be described.
In this example, since there is little difference in the essence of the invention as compared with the first embodiment, a configuration that differs in principle will be referred to, and the description of the first embodiment described above will be used for the common configuration.
This example will be described with reference to FIG. 10. In Embodiment 1 described above, the blade edge 12a of the blade 12 is provided only on one side, but in this example, the blade edge 12a is provided on both sides of the blade 12. Thus, this is an example in which the convenience of use is considered regardless of the right and left classification.
Other configurations are not different from those of the first embodiment.

A fifth embodiment will be described.
In this example, since there is little difference in the essence of the invention as compared with the first embodiment, a configuration that differs in principle will be referred to, and the description of the first embodiment described above will be used for the common configuration.
This example will be described with reference to FIG. 11. In Embodiment 1 described above, the cutting edge 12a of the blade 1 is arranged in the same direction, and the blade 12 is arranged in parallel. In this example, As shown in the figure, six blades 12n1, 12n2, 12n3, 12n4, 12n5, and 12n6 are arranged in non-parallel.
That is, when viewed from the plane, the six blades 12n adjacent to each other have their blade edges a in different directions.
Then, as shown in FIG. 11, six blades 12n1, 12n2, 12n3, 12n4, 12n5, and 12n6 are positioned on the upper side in the drawing from the left end to the right end of the first blade 12n1 (left end). Then, the cutting edge 12a of the second cutting tool 12n2 is directed downward in the drawing, and the cutting tool 12n2 protrudes upward in the drawing. Hereinafter, the cutting edge 12a of the third cutting tool 12n3 is sequentially changed from that of the first cutting tool 12n1. The fourth cutting tool 12n4 is set in common with the cutting edge 12a and the fourth cutting tool 12n4 is set in common with the second cutting tool 12n2. Hereinafter, the above-described configuration is repeated, and the fifth cutting tool 12n5 and the sixth cutting tool ( The right edge) blade 12n6 is configured to be uneven, that is, non-parallel.
In the case of such a configuration, a finger or the like during handling of the razor 10 is located beside the cutting edges 12a of the first blade 12n1 located at the left end and the sixth blade 12n6 located at the right end in the drawing. It is desirable to provide a control member 18 such as a safety pin as described above for the purpose of suppressing obstacles.
On the other hand, the respective blade edges 12a of the blades 12n2, n3, n4, n5 located between these two blades 12n1, n6 are opposite to the blade edges 12a of the respective adjacent blades 12n1, 12n2, n3, n4, n5, n6. Will be located inside each.
Therefore, since the blade edge 12a is located on the inner side opposite to the blade edge 12a of the adjacent blades 12n1, 12n2, n3, n4, n5, and n6, a finger or the like at the time of handling the razor 10 can use these blades 12n1, 12n2, n3. , N4, n5, and n6, the opposite sides of the blade edges 12a interfere with each other. Therefore, the control member 18 described above is not necessarily required except for the blade edges 12a of the blades 12n1 and n6 on both sides.
In particular, when the blades 12n1, 12n2, n3, n4, n5, and n6 are respectively provided in the above-described blade cover 12b, fingers or the like are interfered with the blade cover 12b when the razor 10 is handled. Therefore, there is no risk of injury.

A sixth embodiment will be described.
In this example, since there is little difference in the essence of the invention as compared with the first embodiment, a configuration that differs in principle will be referred to, and the description of the first embodiment described above will be used for the common configuration.
This example will be described with reference to FIG. 12. In the above-described first embodiment, a so-called bristle is not raised around the blade 12, but in this embodiment, the control that also serves as the above-described bristle is provided. A large number of members 18 are raised beside the cutting edge 12a.
The configuration of the blade 12 shown in FIG. 12 is symmetric to the example shown in the fifth embodiment, but is not limited at all.
The term “brissle” in this specification is variously referred to as a brush tooth, a comb tooth, a brush hair, a comb tooth, and the like, and is common to these terms.
In general, the pin is in the shape of an elongated pin, but the shape is not limited as long as the cross section is circular, and the pin is angular and does not damage a finger or the like.
When the control member 18 also serves as a bristle, the hair H can be cut while combing the hair H.
Next, still another embodiment of the present invention will be described.
In the example described below, a haircut replacement razor 20 is detachable from a haircut razor base material 14 in preparation for deterioration due to the use of the blade 12 of the haircut razor 10 described above.
Details of the haircut razor 20 are apparent with reference to FIGS. 13 to 15, but the haircut razor 10 is attached to the haircut razor base material 14 in a non-detachable manner. In the haircut razor 20 for haircut, instead of mounting the blade 12 on the haircut razor base material 14, the difference is that the blade 12 and the control member 18 are provided on the razor base material 22, The description is abbreviate | omitted about the structure which is common with the razor 10 for haircut which was done, and the description is abbreviate | omitted.
Moreover, the structure of the razor base material 22 which makes the haircut razor 10 detachable is also demonstrated (refer FIG.13, FIG.14, FIG.15).
In the haircut razor 10, the blade 12 is erected on the razor base material 22, and the control member 18 is erected beside the blade 12 (see FIGS. 13 and 14).
In this embodiment, five blades 12 are provided, but the number of blades 12 can be freely provided as necessary, as in the case of the haircut razor 10 described above.
The haircut razor 10 is provided so as to be detachable in the fitting hole 24 formed in the razor base material 22, so that the blade base material 22 is provided corresponding to the form of the fitting hole 24. (See FIGS. 13 to 15).
More specifically, one side of the base material 22 is formed as a wavy uneven surface 22 a, while one side of the fitting hole 24 of the haircut razor base material 14 is wavy on one side of the base material 22. Corrugated surface 22a is formed as a corrugated surface (see FIG. 14).
Further, stoppers 22b and 22b are formed on both sides of the base material 22 in the longitudinal direction.
On the other hand, engagement step portions 22e and 22e corresponding to the stoppers 22b and 22b are formed on both sides of the opening of the fitting hole 24 on the surface side of the haircut razor base material 14 (see FIG. 15). ).
Thus, the blade 12 side of the haircut razor 10 is directed from the front surface to the lower surface of the haircut razor base material 14, and the blade base material 22 is fitted into the fitting hole 24 of the haircut razor base material 14.
And the wavy uneven surface 22a of the base material 22 is fitted into the wavy uneven surface of the fitting hole 24 of the hair-cut razor base material 14, and further stoppers 22b, 22b provided on the base material 22 Is supported by the engaging step portions 22e and 22e of the hair-cut razor base material 14, and the hair-cut replacement razor 20 can be securely attached to the hair-cut razor base material 14 without being reluctant, and the hair-cut replacement razor A knob 22c is provided on the base material 22 in preparation for removal (see FIG. 13).
Thus, by fitting the base material 22 of the haircut razor 20 to the fitting hole 24 of the haircut razor base material 14, the cutting tool 12 having the blade edge 12 a becomes the haircut razor base material 14. A haircut razor 10 raised up can be obtained (see FIGS. 13 and 14).
The effect of the haircut razor on which the haircut razor 20 is mounted is the same as that of the haircut razor 10 described above.
When the blade 12 is deteriorated, the haircut replacement razor 20 is removed from the haircut razor base material 14, and a new haircut replacement razor 20 is attached, so that a haircut razor having an excellent cutting function can be easily obtained. Can get to.
Further, another embodiment of the present invention will be described.
That is, as shown in FIG. 20, the haircut razor 10 of the present invention is integrally formed in the bristle of the hair brush, and the density of the bristle is particularly determined between the front side and the rear side of the cutting edge. It can be understood that it is characterized by making it different.
That is, on the side where the bristle density is relatively low, there is less resistance when actually brushing the hair and the like, and the brush is better. On the other hand, on the side where the bristle density is high, the resistance of brushing becomes relatively large, but the brushing itself is delicately and carefully performed, and it is possible to realize a good finished state.
Whether the bristle density on the front or rear side is relatively increased with respect to the cutting edge of the haircut razor 10 may be arbitrarily selected according to the purpose. However, in order to realize the effect of actually performing hair cutting and brushing, it is necessary to make the relative difference in bristle density before and after the blade edge at least 5%. More preferably, the bristle density difference should be 10-30%.
In the present invention, in order to efficiently perform hair cutting and brushing, it is desirable that the bristle density on the front side of the cutting edge is relatively lower than that on the rear side. That is, it is only necessary to prepare a relatively rough hair before cutting the hair at the blade edge, and it is desirable that the hair after the cutting is carefully brushed.

  According to the present invention as described above, it is possible to easily and speedily realize an appropriate and safe haircut operation, and even a person who does not have special technical skills can reliably perform a desired haircut operation. In addition to being able to achieve this, it will be possible to efficiently carry out delicate hair-cutting work that has conventionally required troublesome work even for those who have specialized skills. Therefore, it should be understood that the present invention is superior in industrial applicability.

[Document Name] Description [Title of Invention] Haircut Razor and Haircut Replacement Razor [Technical Field]
The present invention relates to a haircut razor for partially cutting hair and a haircut replacement razor used for a haircut razor.
[Background]
The use of razors for haircuts has been widely used for the purpose of hair cosmetics.
For example, the invention of the form described in JP2003-190675A is known.
In this example, the blade body 32 of the razor 30 is covered with a semicircular protrusion 36 protruding from the blade edge 34 so that the blade edge 34 is intermittently covered, and the exposed blade edge 34a and the coated blade edge 34b are alternately arranged. Is provided.
A groove 38 is provided between the adjacent pair of protrusions 36, 36 for the purpose of limiting the amount of hair when cutting the hair (see FIGS. 12 and 13 ).
[Patent Document 1] JP 2003-190675 A [Disclosure of the Invention]
[Problems to be solved by the invention]
However, in the above-described background art, the amount of hair supplied to the exposed blade edge 34a of the blade body 32 at the time of cutting the hair can be evaluated for the advantage of being stabilized by the protrusion 36, but it is exposed to the hair. The blade edge 34a faces a right angle (cross-shaped) like a known razor of this kind (see FIGS. 14 and 15 ).
Therefore, although moving the razor 30 along the scalp of the head T does not deny that the hair H can be cut reliably, there is a problem in the following points.
Since the blade edge 34a exposed to the hair H faces a right angle, the possibility of excessively cutting the hair H could not be avoided.
This point will be further described with reference to FIGS. 12 to 15. Since the blade edge 34 a of the blade body 32 moves in the direction perpendicular to the hair H as shown in the figure, the hair H is reliably cut. Although the cutting function improves as the angle of inclination of the blade edge 34a increases from the acute angle to the right angle with respect to the hair H, the hair H tends to be excessively cut as the cutting function is improved, and the cutting is not performed. There is a risk that a so-called “tiger trimming phenomenon” may occur due to a difference between the hair part of the part and the hair part of the cut part.
On the other hand, in order to avoid the tiger-cutting phenomenon of the hair H, even if an attempt is made to change the inclination angle of the blade edge 34a in order to suppress excessive hair cutting, the operation is not always easy.
When cutting the hair H of the head with the razor 30 by itself, the hair H on the back of the head, which is difficult to see, is taken into account, and the so-called “hanging” is performed. There is a possibility that the amount of hair cut will be too small or, conversely, the amount of hair cut may be small.
In order to avoid this tiger cutting phenomenon, it is necessary to adjust the contact angle of the blade edge 34a of the razor 30 with respect to the hair H appropriately.
However, setting the inclination angle of the blade edge 34a of the razor 30 to be constant, and maintaining the angle while continuously cutting the hair H is extremely difficult due to the nature of manual operation. It was difficult to adjust the balanced hair H.
The object of the present invention is to solve the problems of the background art configuration described above, without excessively cutting the hair and vice versa. In particular, it is to provide a haircut razor that does not cause the tiger-cutting phenomenon, and to provide a haircut replacement razor for use in the haircut razor.
Another object of the present invention is to provide a haircut razor and a haircut replacement razor that are highly safe and do not cause damage to human fingers or the like due to a knife when handling the haircut razor and haircut replacement razor. It is in.
Other purposes of the haircut razor and haircut replacement razor will be readily understood with reference to the following description and drawings.
[Means for Solving the Problems]
The present invention has been devised through repeated experiments and examinations to solve the problems in the existing technology as described above, and has the following technical characteristics.

In the razor, the blade tips of at least two blades are arranged in the same direction, and the blades are arranged in parallel .
In this specification, the fact that the cutting edge is arranged in a direction perpendicular to the rising direction of the blade means that the cutting edge of the blade is arranged at a right angle (90 degrees) to the rising direction of the blade, The case where the angle is smaller than the right angle includes the case where the angle is larger. In other words, it means that it is only necessary to have an angle in a range that can be rubbed along the hair when cutting the hair.

Yes, 24 is a fitting hole, H is hair, T is a head, and 25 is a hair brush.
Effects Since the first problem solving means is configured as described above, the following effects can be obtained.
The blade side of the haircut razor is directed toward the hair and is generally moved from the top side of the head to the neck side along the scalp.
In this case, the cutting edge of the blade does not touch the hair at a right angle as in the background art, and the cutting edge moves while rubbing the hair. For example, it is cut obliquely from the cutting start portion to the cutting end portion (see FIG. 6).
In this invention, by moving the razor, the cutting edge of the blade is directed downward following the length direction of the hair, and the hair is gradually cut along with the movement of the cutting edge so as to rub or scrape the hair. (See FIGS. 4, 5, and 6).
In this case, since the cutting edge of the blade is cut while being in contact with the hair, the amount of hair cut gradually decreases from the head side to the neck side.
This means that when hair is focused on the fact that the hair root side is generally thicker and gradually narrows toward the hair tip side, the hair is simulated as a natural hair and does not cause so-called tiger cutting (FIGS. 4 and 4). 5, see FIG.
The second problem solving means further contributes to the improvement of the hair cutting function because the cutting edge is inclined with respect to the reference line of the base material for the haircut razor.
That is, the hair is cut along the spherical scalp of the human body. In this case, the cutting edge of the blade moves with a certain range of angle so as to draw an arc.
Therefore, since the cutting edge is inclined in accordance with the angle at the time of movement, a cutting angle close to ideal can be obtained, so that more preferable hair cutting can be performed.
In the third problem solving means, since a control member for suppressing injury at the time of handling the haircut razor is provided beside the blade edge, there is no possibility of causing injury to the finger or the like.
In the fourth problem solving means, since the control member also serves as a bristle, the hair can be cut while combing the hair with the blade and the bristle.
The fifth problem solving means is that this haircut replacement razor is attached to the haircut razor body so that the haircut replacement razor can be replaced in preparation for deterioration of the razor. Can be easily obtained.
The sixth problem solving means contributes to the improvement of the hair cutting function as the second problem solving means because the cutting edge of the blade is inclined with respect to the reference line of the razor base material.
Since the control member which suppresses the injury at the time of handling is provided by the 7th problem-solving means beside the blade edge | tip of a cutter, there is no possibility of causing damage to a finger etc. similarly to the 3rd problem-solving means.
In the eighth problem solving means, since the control member also serves as a bristle, the hair can be cut with the blade and the bristle, and the cutting can be performed in the same manner as the fourth problem solving means.
The ninth problem solving means is that in which the haircut razor is integrated in the bristle of the hair brush, the bristle density on the blade tip side and the blade rear side is made different, so that the hair of the hair during brushing The resistance can be differentiated between the blade tip side and the blade rear side.
In the tenth problem solving means, since the bristle density on the blade edge side is smaller than that on the blade rear side, the resistance of the hair during brushing can be made smaller on the blade edge side than on the blade rear side.
In the eleventh problem solving means, the haircut razor integrated with the hair brush is detachable and replaceable with respect to the brush, so that the sharpness is good like the fifth problem solving means. A haircut razor can be easily obtained at any time.
BEST MODE FOR CARRYING OUT THE INVENTION
The invention of haircut razor 10 and haircut replacement razor 20 according to an embodiment of the present invention will be described with reference to the drawings.
[Example 1]
The haircut razor 10 of Embodiment 1 is demonstrated.
In this example, a cutting tool 12 having a cutting edge 12a is fixed on a razor base material 14 for hair cutting, the cutting tools 12 are arranged in parallel, and the cutting edges 12a of the five cutting tools 12 are in the same direction. This is an example in which the upper blade edge 12a is directed to the left side (see FIG. 1). Although the details will be further described later, the example shown in FIG. 1 is a preferable example in the case of cutting the hair from the right side to the neck side on the back surface of the hair of the scalp of the head T, which can be said to be for the right hand. .
On the other hand, the example shown in FIG. 2 can be said to be for the left hand in which the cutting edge 12a is directed to the right side in the drawing in contrast to the example of FIG.
These examples are basically based on the fact that the blade 12 provided with the blade edge 12a is erected on the razor base material 14 for haircut, and the blade edge 12a is arranged in a direction perpendicular to the rising direction of the blade 12. It is a typical structure.
Although it is common in this type of razor 10 to provide a handle 16 at one end of a haircut razor base material 14, the handle 16 is merely a convenience in use and is essential in the present invention. is not.
Although the number of the blades 12 provided with the cutting edges 12a is basically one, it is generally preferable that two or more, for example, about five as shown in FIGS. 1 and 2 are raised. .
The specific configuration of the blade 12 will be further described with reference to FIG. 3. A rectangular thin plate-shaped blade 12 is placed in a plastic blade cover 12b having a substantially U-shaped cross section, and the blade edge 12a is placed on the open side of the cover 12b. The interior is exposed.
Since the blade 12 is made of metal as is generally known, when cutting the hair of the scalp, attention must be paid to controlling the danger.
Therefore, in the present invention, most of the periphery of the blade 12 except for the blade edge 12a side necessary for cutting the hair is used for the above-mentioned blade so that the blade 12 does not get injured by being in contact with the scalp of the human body during use. It is covered with a cover 12b and a haircut razor base material 14.
In addition, as described above, the blade 12 is generally a thin plate-shaped member, and it cannot be denied that the blade 12 lacks strength. Therefore, the strength of the blade 12 can be increased by installing the blade 12 in the blade cover 12b. It is also intended.
Furthermore, when plastics is employed for the blade cover 12b, the material can advantageously contribute to avoiding injury to the scalp when the razor 10 is used.
As shown in FIG. 3, the cover 12b of the blade 12 has projections 12c slightly protruding beyond the extension line of the blade edge 12a in a direction perpendicular to the extension line of the blade edge 12a of the blade 12 at regular intervals. One is provided.
In addition to being able to increase the strength of the cover 12b by these projections 12c, by providing the projections 12c at regular intervals, the hair H introduced between the adjacent blades 12 at the time of cutting is divided by the projections 12c. it can.
Therefore, since the hair H is not concentrated on the local part of the blade edge 12a, no concentrated stress is exerted on the blade edge 12a, so that the hair H can be cut smoothly and no load is applied to the blade edge 12a.
A pin-like member that is raised beside the blade edge 12a of the blade 12 is a control member 18 that protects the fingertip of the human body when the razor 10 is handled.
The position of the control member 18 is preferably deviated from the center line of the blade edge 12a to the left and right by, for example, about 5 mm so as not to damage the hair H introduced into the blade edge 12a when the hair H is cut.
The effect of the first embodiment of the present invention will be described (see FIGS. 4, 5, and 6).
The blade 12 side of the haircut razor 10 is directed toward the hair H and is generally moved from the top of the head to the neck side along the scalp T.
In this case, the cutting edge 12a of the blade 12 does not contact the hair H in a direction perpendicular to the hair H as in the background art, and the cutting edge 12a moves so as to rub the hair H along the hair H.
This point will be described in more detail. By moving the razor 10, the cutting edge 12a of the blade 12 is directed to the neck side of the human body so as to follow the length direction of the hair H, along the hair H, and The hair H is gradually cut along with the movement in the direction of the arrow Y in FIGS.
In this case, the blade edge 12a of the blade 12 moves in the acute angle direction without moving the blade body 32 in the direction perpendicular to the hair H as in the background art.
The cutting edge 12a moving in the acute angle direction gradually moves from the hair H positioned above the head to the hair H positioned on the neck side. In this case, the moving direction of the cutting edge 12a is relative to the hair H. Since the blade edge 12a never moves in a direction perpendicular to the hair H because it is an acute angle direction that is nearly parallel to the hair H, the hair edge 34a is different from that in which the blade edge 34a of the background art moves in a direction perpendicular to the hair. Since the hair H can be cut in a sharp manner and the tape H can be obtained, it is possible to make up the hair without any discomfort (see FIG. 6).
Therefore, since there is no difference in the cut amount between the cut portion and the non-cut portion of the hair H, the hair can be adjusted and averaged without causing tiger cutting.
[Example 2]
Embodiment 2 will be described.
In this example, since there is little difference in the essence of the invention as compared with the first embodiment, a configuration that differs in principle will be referred to, and the description of the first embodiment described above will be used for the common configuration.
This example will be described with reference to FIGS. 7 and 8. In the first embodiment, the blade 12 is provided in parallel without being inclined. In this embodiment, the blade edge of the blade 12 is provided. While the direction of 12a is set in the same direction, there are provided one inclined to the upper right on the drawing with respect to the reference line L and one inclined to the upper left on the drawing with the reference line L as a boundary. (See FIGS. 7 and 8).
Therefore, this embodiment is common to Embodiment 1 in that it is used for right hand and left hand in use.
The angle of the blade edge 12a with respect to the hair H when the haircut razor 10 is used is often different depending on the user's preference, the combing part of the hair H, and the part to be cut.
Furthermore, the angle with respect to the hair H is also expected to be different depending on the difference in dominant arm.
Therefore, the inventor tried to study the use angle experimentally in consideration of the difference in the use conditions.
As a result, for example, when the dominant arm is right-handed and the hair H of the right occipital region is moved from the right side toward the neck, the hair cutting razor 10 is moved diagonally, and the hair H is combed and cut. The inclination angle of the cutting edge 12a of the blade 12 is in the range of 10 to 80 degrees, preferably about 60 degrees, in the upper left of the drawing with respect to the reference line L of the base material 14 for the haircut razor. It turned out to be appropriate (see FIG. 7).
On the other hand, the inclination angle when the dominant arm is a left-handed person and the hair H of the left occipital region is combed and cut is based on the reference line L of the haircut razor base material 14 symmetrically with the above. On the other hand, it has been found that the range of 100 to 170 degrees in the upper right of the drawing, preferably 120 degrees, is appropriate (see FIG. 8).
[Example 3]
Next, still another embodiment of the present invention will be described.
In the example described below, a haircut replacement razor 20 is detachable from a haircut razor base material 14 in preparation for deterioration due to the use of the blade 12 of the haircut razor 10 described above.
The details of the haircut razor 20 are apparent with reference to FIGS. 9 to 11, but the haircut razor 10 is attached to the haircut razor base material 14 in a non-detachable manner. In the haircut razor 20 for haircut, instead of attaching the blade 12 to the haircut razor base material 14, the difference is that the blade 12 and the control member 18 are provided on the razor base material 22. The description is abbreviate | omitted about the structure which is common with the razor 10 for haircut which was done, and the description is abbreviate | omitted.
Moreover, the structure of the base material 22 for razors which makes the haircut razor 10 detachable is also demonstrated (refer FIG.9, FIG.10, FIG.11).
In the haircut razor 10, the blade 12 is erected on the razor base material 22, and the control member 18 is erected beside the blade 12 (see FIGS. 9 and 10).
In this embodiment, five blades 12 are provided, but the number of blades 12 can be freely provided as necessary, as in the case of the haircut razor 10 described above.
The haircut razor 10 is provided so as to be detachable in the fitting hole 24 formed in the razor base material 22, so that the blade base material 22 is provided corresponding to the form of the fitting hole 24. (See FIGS. 9 to 11).
More specifically, one side of the base material 22 is formed as a wavy uneven surface 22 a, while one side of the fitting hole 24 of the haircut razor base material 14 is wavy on one side of the base material 22. Corrugated surface 22a is formed as a corrugated surface (see FIGS. 9 and 10).
Further, stoppers 22b and 22b are formed on both sides of the base material 22 in the longitudinal direction.
On the other hand, engagement step portions 22e and 22e corresponding to the stoppers 22b and 22b are formed on both sides of the opening of the fitting hole 24 on the surface side of the haircut razor base material 14 (see FIG. 11). ).
Thus, the blade 12 side of the haircut razor 10 is directed from the front surface to the lower surface of the haircut razor base material 14, and the blade base material 22 is fitted into the fitting hole 24 of the haircut razor base material 14.
And the wavy uneven surface 22a of the base material 22 is fitted into the wavy uneven surface of the fitting hole 24 of the hair-cut razor base material 14, and further stoppers 22b, 22b provided on the base material 22 Is supported by the engaging step portions 22e and 22e of the hair-cut razor base material 14, and the hair-cut replacement razor 20 can be securely attached to the hair-cut razor base material 14 without being reluctant, and the hair-cut replacement razor A knob 22c is provided on the base material 22 in preparation for removal (see FIG. 9).
Thus, by fitting the base material 22 of the haircut razor 20 to the fitting hole 24 of the haircut razor base material 14, the cutting tool 12 having the blade edge 12 a becomes the haircut razor base material 14. A haircut razor 10 raised up can be obtained (see FIGS. 9 and 11).
The effect of the haircut razor on which the haircut razor 20 is mounted is the same as that of the haircut razor 10 described above.
When the blade 12 is deteriorated, the haircut razor 20 is removed from the haircut razor base material 14 and a new haircut razor 20 is attached, so that a haircut razor with an excellent cutting function can be easily obtained. Can get to.
Further, another embodiment of the present invention will be described.
That is, as shown in FIG. 16, the haircut razor 10 according to the present invention is integrally formed in the bristle of the hair brush, and the density of the bristle is particularly determined between the front side and the rear side of the cutting edge. It can be understood that it is characterized by making it different.
That is, on the side where the bristle density is relatively low, there is less resistance when actually brushing the hair and the like, and the brush is better. On the other hand, on the side where the bristle density is high, the resistance of brushing becomes relatively large, but the brushing itself is delicately and carefully performed, and it is possible to realize a good finished state.
The term “brissle” in this specification is variously referred to as a brush tooth, a comb tooth, a brush hair, a comb tooth, and the like, and is common to these terms.
In general, the pin is in the shape of an elongated pin, but the shape is not limited as long as the cross section is circular, and the pin is angular and does not damage a finger or the like.
When the control member 18 also serves as a bristle, the hair H can be cut while combing the hair H.
Whether the bristle density on the front or rear side is relatively increased with respect to the cutting edge of the haircut razor 10 may be arbitrarily selected according to the purpose. However, in order to realize the effect of actually performing hair cutting and brushing, it is necessary to make the relative difference in bristle density before and after the blade edge at least 5%. More preferably, the bristle density difference should be 10-30%.
In the present invention, in order to efficiently perform hair cutting and brushing, it is desirable that the bristle density on the front side of the cutting edge is relatively lower than that on the rear side. That is, it is only necessary to prepare a relatively rough hair before cutting the hair at the blade edge, and it is desirable that the hair after the cutting is carefully brushed.
[Industrial applicability]
According to the present invention as described above, it is possible to easily and speedily realize an appropriate and safe haircut operation, and even a person who does not have special technical skills can reliably perform a desired haircut operation. In addition to being able to achieve this, it will be possible to efficiently carry out delicate hair-cutting work that has conventionally required troublesome work even for those who have specialized skills. Therefore, it should be understood that the present invention is superior in industrial applicability.

[Document Name] Description [Title of Invention] Haircut Razor and Haircut Replacement Razor [Technical Field]
The present invention relates to a haircut razor for partially cutting hair and a haircut replacement razor used for a haircut razor.
[Background]
The use of razors for haircuts has been widely used for the purpose of hair cosmetics.
For example, the invention of the form described in JP2003-190675A is known.
In this example, the blade body 32 of the razor 30 is covered with a semicircular protrusion 36 protruding from the blade edge 34 so that the blade edge 34 is intermittently covered, and the exposed blade edge 34a and the coated blade edge 34b are alternately arranged. Is provided.
A groove 38 is provided between the adjacent pair of protrusions 36, 36 for the purpose of limiting the amount of hair to be cut when the hair is cut (see FIGS. 12 and 13).
[Patent Document 1] JP 2003-190675 A [Disclosure of the Invention]
[Problems to be solved by the invention]
However, in the above-described background art, the amount of hair supplied to the exposed blade edge 34a of the blade body 32 at the time of cutting the hair can be evaluated for the advantage of being stabilized by the protrusion 36, but it is exposed to the hair. The blade edge 34a faces a right angle (cross-shaped) like a known razor of this kind (see FIGS. 14 and 15).
Therefore, although moving the razor 30 along the scalp of the head T does not deny that the hair H can be cut reliably, there is a problem in the following points.
Since the blade edge 34a exposed to the hair H faces a right angle, the possibility of excessively cutting the hair H could not be avoided.
This point will be further described with reference to FIGS. 12 to 15. Since the blade edge 34 a of the blade body 32 moves in a direction perpendicular to the hair H as shown in the figure, the hair H is reliably cut. Although the cutting function improves as the angle of inclination of the blade edge 34a increases from the acute angle to the right angle with respect to the hair H, the hair H tends to be excessively cut as the cutting function is improved, and the cutting is not performed. There is a risk that a so-called “tiger trimming phenomenon” may occur due to a difference between the hair part of the part and the hair part of the cut part.
On the other hand, in order to avoid the tiger-cutting phenomenon of the hair H, even if an attempt is made to change the inclination angle of the blade edge 34a in order to suppress excessive hair cutting, the operation is not always easy.
When cutting the hair H of the head with the razor 30 by itself, the hair H on the back of the head, which is difficult to see, is taken into account, and the so-called “hanging” is performed. There is a possibility that the amount of hair cut will be too small or, conversely, the amount of hair cut may be small.
In order to avoid this tiger cutting phenomenon, it is necessary to adjust the contact angle of the blade edge 34a of the razor 30 with respect to the hair H appropriately.
However, setting the inclination angle of the blade edge 34a of the razor 30 to be constant, and maintaining the angle while continuously cutting the hair H is extremely difficult due to the nature of manual operation. It was difficult to adjust the balanced hair H.
The object of the present invention is to solve the problems of the background art configuration described above, without excessively cutting the hair and vice versa. In particular, it is to provide a haircut razor that does not cause the tiger-cutting phenomenon, and to provide a haircut replacement razor for use in the haircut razor.
Another object of the present invention is to provide a haircut razor and a haircut replacement razor that are highly safe and do not cause damage to human fingers or the like due to a knife when handling the haircut razor and haircut replacement razor. It is in.
Other purposes of the haircut razor and haircut replacement razor will be readily understood with reference to the following description and drawings.

Effects Since the first problem solving means is configured as described above, the following effects can be obtained.
The blade side of the haircut razor is directed toward the hair and is generally moved from the top side of the head to the neck side along the scalp.
In this case, the cutting edge of the blade does not touch the hair at a right angle as in the background art, and the cutting edge moves while rubbing the hair. For example, it is cut obliquely from the cutting start portion to the cutting end portion (see FIG. 6).
In this invention, by moving the razor, the cutting edge of the blade is directed downward following the length direction of the hair, and the hair is gradually cut along with the movement of the cutting edge so as to rub or scrape the hair. (See FIGS. 4, 5, and 6).
In this case, since the cutting edge of the blade is cut while being in contact with the hair, the amount of hair cut gradually decreases from the head side to the neck side.
This means that when hair is focused on the fact that the hair root side is generally thicker and gradually narrows toward the hair tip side, the hair is simulated as a natural hair and does not cause so-called tiger cutting (FIGS. 4 and 4). 5, see FIG.
Second means for solving the problem, the knives are, because becomes disposed with orientation so as to intersect the reference line L and the acute angle parallel to the longitudinal direction of the hair cutting razor preform, further, improved hair cutting function Contributes to
That is, the hair is cut along the spherical scalp of the human body. In this case, the cutting edge of the blade moves with a certain range of angle so as to draw an arc.
Therefore, since the cutting edge is inclined in accordance with the angle at the time of movement, a cutting angle close to ideal can be obtained, so that more preferable hair cutting can be performed.
In the third problem solving means, since a control member for suppressing injury at the time of handling the haircut razor is provided beside the blade edge, there is no possibility of causing injury to the finger or the like.
In the fourth problem solving means, since the control member is an elongated pin-shaped member, the hair can be cut while combing the hair with the blade and the elongated pin-shaped member .
The fifth problem solving means is that this haircut replacement razor is attached to the haircut razor body so that the haircut replacement razor can be replaced in preparation for deterioration of the razor. Can be easily obtained.
Sixth means for solving the problem, the knives are, because becomes disposed with orientation so as to intersect the reference line L and the acute angle parallel to the longitudinal direction of the razor preform, as in the second means for solving problems hair This contributes to the improvement of the cutting function.
Since the control member which suppresses the injury at the time of handling is provided by the 7th problem-solving means beside the blade edge | tip of a cutter, there is no possibility of causing damage to a finger etc. similarly to the 3rd problem-solving means.
In the eighth problem solving means, since the control member is an elongated pin-shaped member, the hair can be cut with the blade and the elongated pin-shaped member , and cutting can be performed in the same manner as the fourth problem solving means.
The ninth problem solving means is that in which the haircut razor is integrated into the elongated pin-shaped member of the hair brush, the density of the elongated pin-shaped member on the blade tip side and the blade rear side is made different. The resistance of the hair during brushing can be differentiated between the blade tip side and the blade back side.
In the tenth problem solving means, since the density of the elongated pin-like members on the blade edge side is made smaller than that on the blade back side, the resistance of the hair during brushing can be made smaller on the blade edge side than on the blade back side. .
In the eleventh problem solving means, the haircut razor integrated with the hair brush is detachable and replaceable with respect to the brush, so that the sharpness is good like the fifth problem solving means. A haircut razor can be easily obtained at any time.
BEST MODE FOR CARRYING OUT THE INVENTION
The invention of haircut razor 10 and haircut replacement razor 20 according to an embodiment of the present invention will be described with reference to the drawings.
[Example 1]
The haircut razor 10 of Embodiment 1 is demonstrated.
This example, blades 12 having a cutting edge 12a is fixed on the sword preform 14 shaved Heaka' DOO, blades 12 is a parallel, each of the cutting edge 12a of the five blades 12 is a same direction drawings This is an example in which the upper blade edge 12a is directed to the left side (see FIG. 1). Although the details will be further described later, the example shown in FIG. 1 is a preferable example in the case of cutting the hair from the right side to the neck side on the back surface of the hair of the scalp of the head T, which can be said to be for the right hand. .
On the other hand, the example shown in FIG. 2 can be said to be for the left hand in which the cutting edge 12a is directed to the right side in the drawing in contrast to the example of FIG.
These examples are basically that the blade 12 having a cutting edge 12a respectively are TatsuOkoshi sword preform 14 shaved Heaka' DOO, are arranged in a perpendicular direction that the cutting edge 12a is against TatsuOkoshi direction of the blade 12 It is a typical structure.
Providing a handle 16 at one end of Heaka' preparative razor blade preform 14 is common in the razor 10 of this kind, but because the handle 16 is of mere convenience of use, as an essential in the present invention is not.
Although the number of the blades 12 provided with the cutting edges 12a is basically one, it is generally preferable that two or more, for example, about five as shown in FIGS. 1 and 2 are raised. .
The specific configuration of the blade 12 will be further described with reference to FIG. 3. A rectangular thin plate-shaped blade 12 is placed in a plastic blade cover 12b having a substantially U-shaped cross section, and the blade edge 12a is placed on the open side of the cover 12b. The interior is exposed.
Since the blade 12 is made of metal as is generally known, when cutting the hair of the scalp, attention must be paid to controlling the danger.
Therefore, in the present invention, most of the periphery of the blade 12 except for the blade edge 12a side necessary for cutting the hair is used for the above-mentioned blade so that the blade 12 does not get injured by being in contact with the scalp of the human body during use. It is covered by a cover 12b and Heaka' preparative razor blade preform 14.
In addition, as described above, the blade 12 is generally a thin plate-shaped member, and it cannot be denied that the blade 12 lacks strength. Therefore, the strength of the blade 12 can be increased by installing the blade 12 in the blade cover 12b. It is also intended.
Furthermore, when plastics is employed for the blade cover 12b, the material can advantageously contribute to avoiding injury to the scalp when the razor 10 is used.
As shown in FIG. 3, the cover 12b of the blade 12 has projections 12c slightly protruding beyond the extension line of the blade edge 12a in a direction perpendicular to the extension line of the blade edge 12a of the blade 12 at regular intervals. One is provided.
In addition to being able to increase the strength of the cover 12b by these projections 12c, by providing the projections 12c at regular intervals, the hair H introduced between the adjacent blades 12 at the time of cutting is divided by the projections 12c. it can.
Therefore, since the hair H is not concentrated on the local part of the blade edge 12a, no concentrated stress is exerted on the blade edge 12a, so that the hair H can be cut smoothly and no load is applied to the blade edge 12a.
A pin-like member that is raised beside the blade edge 12a of the blade 12 is a control member 18 that protects the fingertip of the human body when the razor 10 is handled.
The position of the control member 18 is preferably deviated from the center line of the blade edge 12a to the left and right by, for example, about 5 mm so as not to damage the hair H introduced into the blade edge 12a when the hair H is cut.
The effect of the first embodiment of the present invention will be described (see FIGS. 4, 5, and 6).
The blade 12 side of the Heaka' preparative razor blade 10 toward the hair H, and thereby along the scalp T is generally moved to the neck side from the top of the head.
In this case, the cutting edge 12a of the blade 12 does not contact the hair H in a direction perpendicular to the hair H as in the background art, and the cutting edge 12a moves so as to rub the hair H along the hair H.
This point will be described in more detail. By moving the razor 10, the cutting edge 12a of the blade 12 is directed to the neck side of the human body so as to follow the length direction of the hair H, along the hair H, and The hair H is gradually cut along with the movement in the direction of the arrow Y in FIGS.
In this case, the blade edge 12a of the blade 12 moves in the acute angle direction without moving the blade body 32 in the direction perpendicular to the hair H as in the background art.
The cutting edge 12a moving in the acute angle direction gradually moves from the hair H positioned above the head to the hair H positioned on the neck side. In this case, the moving direction of the cutting edge 12a is relative to the hair H. Since the blade edge 12a never moves in a direction perpendicular to the hair H because it is an acute angle direction that is nearly parallel to the hair H, the hair edge 34a is different from that in which the blade edge 34a of the background art moves in a direction perpendicular to the hair. Since the hair H can be cut in a sharp manner and the tape H can be obtained, it is possible to make up the hair without any discomfort (see FIG. 6).
Therefore, since there is no difference in the cut amount between the cut portion and the non-cut portion of the hair H, the hair can be adjusted and averaged without causing tiger cutting.
[Example 2]
A second embodiment will be described.
In this example, since there is little difference in the essence of the invention as compared with the first embodiment, a configuration that differs in principle will be referred to, and the description of the first embodiment described above will be used for the common configuration.
This example will be described with reference to FIGS. 7 and 8. In the first embodiment, the blade 12 is provided in parallel without being inclined. In this embodiment, the blade edge of the blade 12 is provided. While the direction of 12a is set in the same direction, there are provided one inclined to the upper right on the drawing with respect to the reference line L and one inclined to the upper left on the drawing with the reference line L as a boundary. (See FIGS. 7 and 8).
Therefore, this embodiment is common to Embodiment 1 in that it is used for right hand and left hand in use.
The angle of the blade edge 12a with respect to the hair H when the haircut razor 10 is used is often different depending on the user's preference, the combing part of the hair H, and the part to be cut.
Furthermore, the angle with respect to the hair H is also expected to be different depending on the difference in dominant arm.
Therefore, the inventor tried to study the use angle experimentally in consideration of the difference in the use conditions.
As a result, for example, when the dominant arm is right-handed and the hair H of the right occipital region is moved from the right side toward the neck, the hair cutting razor 10 is moved diagonally, and the hair H is combed and cut. The inclination angle of the cutting edge 12a of the blade 12 is in the range of 10 to 80 degrees, preferably about 60 degrees, in the upper left of the drawing with respect to the reference line L of the base material 14 for the haircut razor. It turned out to be appropriate (see FIG. 7).
On the other hand, the inclination angle when the dominant arm is a left-handed person and the hair H of the left occipital region is combed and cut is based on the reference line L of the haircut razor base material 14 symmetrically with the above. On the other hand, it has been found that the range of 100 to 170 degrees in the upper right of the drawing, preferably 120 degrees, is appropriate (see FIG. 8).
[Example 3]
Next, still another embodiment of the present invention will be described.
In the example described below, a haircut replacement razor 20 is detachable from a haircut razor base material 14 in preparation for deterioration due to the use of the blade 12 of the haircut razor 10 described above.
The details of the haircut razor 20 are apparent with reference to FIGS. 9 to 11, but the haircut razor 10 is attached to the haircut razor base material 14 in a non-detachable manner. In the haircut razor 20 for haircut, instead of attaching the blade 12 to the haircut razor base material 14, the difference is that the blade 12 and the control member 18 are provided on the razor base material 22. The description is abbreviate | omitted about the structure which is common with the razor 10 for haircut which was done, and the description is abbreviate | omitted.
Moreover, the structure of the base material 22 for razors which makes the haircut razor 10 detachable is also demonstrated (refer FIG.9, FIG.10, FIG.11).
In the haircut razor 10, the blade 12 is erected on the razor base material 22, and the control member 18 is erected beside the blade 12 (see FIGS. 9 and 10).
In this embodiment, five blades 12 are provided, but the number of blades 12 can be freely provided as necessary, as in the case of the haircut razor 10 described above.
The haircut razor 10 is provided so as to be detachable in the fitting hole 24 formed in the razor base material 22, so that the blade base material 22 is provided corresponding to the form of the fitting hole 24. (See FIGS. 9 to 11).
More specifically, one side of the base material 22 is formed as a wavy uneven surface 22 a, while one side of the fitting hole 24 of the haircut razor base material 14 is wavy on one side of the base material 22. Corrugated surface 22a is formed as a corrugated surface (see FIGS. 9 and 10).
Further, stoppers 22b and 22b are formed on both sides of the base material 22 in the longitudinal direction.
On the other hand, engagement step portions 22e and 22e corresponding to the stoppers 22b and 22b are formed on both sides of the opening of the fitting hole 24 on the surface side of the haircut razor base material 14 (see FIG. 11). ).
Thus, the blade 12 side of the haircut razor 10 is directed from the front surface to the lower surface of the haircut razor base material 14, and the blade base material 22 is fitted into the fitting hole 24 of the haircut razor base material 14.
And the wavy uneven surface 22a of the base material 22 is fitted into the wavy uneven surface of the fitting hole 24 of the hair-cut razor base material 14, and further stoppers 22b, 22b provided on the base material 22 Is supported by the engagement step portions 22e and 22e of the haircut razor base material 14, and the haircut razor 20 can be securely attached to the haircut razor base material 14 without being reluctant, and the haircut replacement razor A knob 22c is provided on the base material 22 in preparation for removal (see FIG. 9).
Thus, by fitting the base material 22 of the haircut razor 20 to the fitting hole 24 of the haircut razor base material 14, the cutting tool 12 having the cutting edge 12 a becomes the haircut razor base material 14. A haircut razor 10 raised up can be obtained (see FIGS. 9 and 11).
Effects of the hair-cutting razor haircut replacement razor 20 is attached, it is common to the effects of the hair-cutting razor 10 described above.
When the blade 12 is deteriorated, the haircut replacement razor 20 is removed from the haircut razor base material 14, and a new haircut replacement razor 20 is attached, so that a haircut razor having an excellent cutting function can be easily obtained. Can get to.
Further, another embodiment of the present invention will be described.
That is, typically a embodiment allowed integrally constituting the hair-cutting razor 10 of the present invention in an elongated pin-shaped portion member of hairbrush as shown in FIG. 16, the density of especially the elongate pin-like member It can be understood that the feature is that the front side and the rear side of the cutting edge are different.
That is, on the side where the density of the relatively long and narrow pin-shaped member is low, there is less resistance when actually brushing the hair and the like, and the brush is good. On the other hand, the brushing resistance is relatively increased on the high-density side of the elongated pin-shaped member, but the brushing itself is delicately and carefully performed, and a good finished state can be realized.
"Elongate pin-like member", brush teeth, combing teeth, brush bristles, or the like can be used comb, addition lateral cross section is circular, angular any form unless such as to provide injury such as finger Absent.
When the control member 18 is an elongated pin-shaped member , the hair H can be cut while combing the hair H.
Whether to increase the density of the elongated pin-shaped member on the front or rear side relative to the cutting edge of the haircut razor 10 may be arbitrarily selected according to the purpose. However, in order to realize the effect of actually performing hair cutting and brushing, it is necessary to set the relative difference in the density of the elongated pin-shaped members before and after the cutting edge to at least 5%. More preferably, the difference in the density of the elongated pin-shaped members should be 10 to 30%.
To efficiently perform hair cutting and brushing in the present invention is desirably as relatively lower than the rear side the density of elongate pin-like member in front of the cutting edge. That is, it is only necessary to prepare a relatively rough hair before cutting the hair at the blade edge, and it is desirable that the hair after the cutting is carefully brushed.
[Industrial applicability]
According to the present invention as described above, it is possible to easily and speedily realize an appropriate and safe haircut operation, and even a person who does not have special technical skills can reliably perform a desired haircut operation. In addition to being able to achieve this, it will be possible to efficiently carry out delicate hair-cutting work that has conventionally required troublesome work even for those who have specialized skills. Therefore, it should be understood that the present invention is superior in industrial applicability.
