COMB
Abstract
A comb includes three rows of outer and inner comb teeth, and a
pitch dimension of the inner comb teeth is narrower than pitch
dimensions of the outer comb teeth. Each inner comb tooth is formed
with a stepped part at an intermediate position in a protruding
direction thereof, and a height of a tip end of each comb tooth are
different from each other and a depth of a tooth bottom are also
different from each other. By providing the three rows and the
stepped part, hair is easily caught with each comb tooth entirely.
As a result, resistance can be increased, suitable tension can be
obtained, and backcombed hair can easily be formed. Moreover, the
height and depth of each tooth of the inner comb teeth are
differentiated to distribute the resistance, fewer
sweater-pill-like portions are generated, and backcombed hair can
be formed uniformly.

Description
TECHNICAL FIELD
[0001] The present invention relates to a comb, where a plurality
of comb teeth protruding from a comb main body are arrayed. The
present invention particularly relates to a comb which is devised
in the shape etc. of the comb teeth so that backcombed hair can
efficiently be set.
BACKGROUND ART
[0002] Conventionally, various types of combs exist, and such combs
are used by a beautician, a barber, etc., to hairdress (to set
hair) or cut hair of a customer, other than the purpose of a user
using the combs, for example, for hairdressing his/her own hair.
Various techniques exist for the hairdressing method using a comb,
and one of the hairdressing methods is a backcomb (a technique of
puffing up or teasing hair).
[0003] FIG. 21 illustrates one example of a method of backcombing
(a method of puffing up or teasing hair). This method includes
extracting a given volume of hair bundle from bangs, pulling up the
hair bundle from a forehead of a user. The method also includes
inserting a comb into the hair bundle, and moving the comb from a
tip end side of the hair to a root side (a movement in an arrow
direction in FIG. 19) so that the comb draws through the hair
bundle to form backcombed hair which is comprised of a curled hair
portion at the hair root part (hair root section) of the hair
bundle (to puff up or tease hair). A voluminous hair style can be
achieved by such a curled hair portion (the backcombed hair). Note
that, although FIG. 21 illustrates one example in which the
backcombed hair is formed at the root part of the hair, it is also
possible to backcomb the hair in either one of an intermediate part
(intermediate section) of the hair and a tip end part (tip end
section), or all parts of the hair within the range from the root
part to the tip end part. Further, in order to finish a hair style
based on the backcombed hair, it is common to use a comb with a
narrow comb teeth interval (a so-called fine-toothed comb) and
perform a hairdressing in which the surface of backcombed hair is
smoothed down by the comb to form the hair part at the surface of
backcombed hair so as to flow into a certain direction, as a final
hair setting. Note that hairdressing may be performed so that a
hair part around the backcombed hair covers the surface of the
backcombed hair. Such a hair setting by using the backcombed hair
is effective in achieving the voluminous hair for a person who has
thin or fine hair, and thus, it is a popular hair setting method in
western countries etc. where many people have thin or fine
hair.
[0004] As one example of a conventional comb which is used for the
backcombing described above, Patent Document 1 discloses a comb
which has comb teeth dramatically shortened in the overall length
(3 mm to 7 mm). Moreover, Patent Document 2 discloses a comb which
is formed with, in addition to normal comb teeth (first comb
teeth), second comb teeth that protrude sideways from a side
surface part of a comb main body to keep the voluminous hair with
the backcombing.
[0005] Note that, although it is not related to the backcombing,
examples of a comb which has a characteristic shape are illustrated
by using combs disclosed in Patent Documents 3 to 8. For example,
Patent Document 3 discloses a comb where root side parts between
adjacent comb teeth are blocked, and Patent Document 4 discloses a
comb where a shallow slit is alternately formed in comb teeth.
Moreover, Patent Document 5 discloses a comb where taller comb
teeth and shorter comb teeth are alternately arrayed and tooth tips
are sharpened in an upper part of each shorter comb tooth, and,
further, Patent Document 6 discloses a comb where a group of thick
comb teeth and a group of thin comb teeth are alternately
arrayed.
[0006] Patent Document 7 discloses a comb for a shag haircut which
is formed with a protruding portion (convex) at a part of a teeth
root to provide a portion having different comb teeth lengths, and
Patent Document 8 discloses a comb where first longer comb teeth
and second shorter comb teeth are arrayed so as to form
concave-convex teeth tips at each comb tooth (zigzag shape).

DISCLOSURE OF THE INVENTION
Problems to be Solved by the Invention
[0023] Since the comb in accordance with Patent Document 1 has the
extremely short comb teeth, an amount of hair which enters into a
gap between the comb teeth decreases, and thereby an amount of
backcombed hair which can be formed as the result is limited.
Therefore, in order to make the hair voluminous, it is necessary to
repeat the procedure of backcombing, and thus, it is burdensome.
Further, there is also a problem that a part of the hair is formed
locally and compactly like sweater pills (fluff), and thus, it is
difficult to uniformly form the voluminous backcombed hair as a
whole. Further, as for the comb in accordance with Patent Document
1, hair is pressed against the tooth bottoms of the comb in order
to backcomb the hair. However, as for the comb in accordance with
Patent Document 1, since the depth of the tooth bottoms is constant
or uniform, the hair to be set hits the tooth bottoms uniformly.
Therefore, there is also a problem of it being difficult to obtain
tension in the hair which is suitable for backcombing the hair
(tension obtained by pressing the comb against the hair) unless the
comb is strongly pressed against the hair.
[0024] As for the comb in accordance with Patent Document 2, when
backcombing the hair, in order to improve the durability of the
voluminousness created by the backcomb, it is necessary to use both
the first comb teeth and the second comb teeth. Therefore, since it
is significantly different in the way to use the comb from the
normal comb, there is a problem that a special technique is
required for the way to use each of the comb teeth (the first comb
teeth and the second comb teeth).
[0025] Moreover, generally, in order to efficiently puff up or
tease the hair upon backcombing the hair, it is important to
suitably increase a degree to which the comb is caught by the hair
when combing the hair from the tip toward the root by the comb
(equivalent to a degree to which the hair is pulled by the comb,
tension in the hair, friction or resistance between the comb and
the hair, etc.) within a range in which the hair is not damaged
(the hair surface is not damaged). Even if the combs in accordance
with Patent Documents 3 to 8 described above are used for
backcombing the hair, a problem will arise in which a given amount
of the hair required for the backcombing cannot be suitably caught,
or is caught too much and causes damage to the hair, etc.
[0026] For example, in order to divide a hair bundle for hair
dyeing, the comb in accordance with Patent Document 3 has larger
gaps between the comb teeth compared with the normal combs.
Therefore, resistance between the comb teeth is reduced when
backcombing the hair, and thus, the hair is not easily caught
between the comb teeth. Accordingly, a suitable tension cannot be
obtained in the hair, but the hair is directly caught at the tooth
bottoms between the comb teeth, and thus, it is easy to damage the
hair at edges of the tooth bottoms. Moreover, as for the comb in
accordance with Patent Document 4, since the hair tends to escape
from the shallow slits at the comb teeth which have the shallow
slits, a sufficient amount of hair cannot be backcombed by the
shallow slits. Moreover, since a difference in a depth between the
shallow slits and the normal tooth bottoms is too large, it is
difficult to set the backcombed hair uniformly. A similar problem
with the comb in accordance with Patent Document 4 arises in the
comb in accordance with Patent Document 5 because it has a
structure in which a difference in the depth of the tooth bottoms
between the wider tip side and the comb main body side is too
large. Therefore, since the hair tends to fall out from the tooth
tips provided in the upper part of the short comb teeth, the hair
cannot efficiently be backcombed.
[0027] The comb in accordance with Patent Document 6 is a
traditional Japanese boxwood comb (a comb made of a Japanese
boxwood), and it is not originally made in consideration of being
used for backcombing the hair. Thus, even if the boxwood comb is
forcibly used for backcombing the hair, since an interval of thick
teeth in the group of thick comb teeth is large, the hair cannot
appropriately be backcombed because the hair does not tend to be
caught, and the hair is easily damaged because the edge of each
part is sharp. Moreover, as for the comb in accordance with Patent
Document 7, the hair cannot be puffed up or teased easily because
the one large protruding portion on the tooth bottom side becomes
obstructive. Further, as for the comb in accordance with Patent
Document 8, since the bottom depths between the teeth are the same
at the first long comb teeth and the first short comb teeth, except
for a center part in the longitudinal direction, the tension in the
hair which is caught at the tooth bottoms is uniform, and thus, it
is a problem that it is difficult to form the backcombed hair
uniformly. Note that some comb products which are made of a
synthetic resin or plastic and are not high in quality may have
burrs which are projected from the perimeter of the comb teeth. It
is known in practice that, if such a comb with burrs projected
therefrom is used, the hair tends to be caught easily and the
backcombed hair can easily be formed. However, since the burrs have
a thin and sharp perimeter, it is a problem that the hair is
damaged by such burrs excessively.
[0028] The present invention is made in view of the situations
described above, and one purpose of the present invention is to
provide a comb which is provided with stepped parts at intermediate
positions of comb teeth in a direction parallel to a protruding
direction of the comb teeth to additionally form hair catching
parts when backcombing the hair, and which can easily obtain a
suitable tension required for backcombing the hair, while the hair
is damaged as little as possible.
[0029] Further, another purpose of the present invention is to
provide a comb in which portions from tip end sides of the comb
teeth to the stepped parts, or a portion from the stepped part to a
root side, are tapered to form perimeters of the comb teeth
themselves into a shape which causes more resistance to the hair.
Therefore, suitable tension required for backcombing the hair can
easily be obtained.
[0030] Further, another purpose of the present invention is to
provide a comb in which tip end heights of the comb teeth or depths
of tooth bottoms are formed different from each other to disperse
the hair catching state. Therefore, it is easy to backcomb the hair
with a uniform voluminousness.
[0031] Further, another purpose of the present invention is to
provide a comb in which comb teeth where stepped parts are not
formed are arrayed to increase the number of hair catching parts by
the plurality of rows of comb teeth.
[0032] Further, another purpose of the present invention is to
provide a comb in which a shape of tooth bottoms is devised so as
to cause the hair as little damage as possible by the tooth
bottoms, and to be able to easily obtain tension stronger than that
of the conventional arts.
SUMMARY OF THE INVENTION
[0033] In order to solve the problems described above, in a comb in
accordance with one aspect of the present invention, a plurality of
comb teeth protruding from a comb main body having a longitudinal
direction thereof are arrayed. Each comb tooth has a stepped part
that is formed at an intermediate position of the comb tooth in a
protruding direction thereof. A first section of each comb tooth
that extends from a tip end side to the stepped part has a smaller
dimension in a direction perpendicular to the protruding direction
of the comb tooth, compared with a second section that extends from
the stepped part to a root side.
[0034] Further, in the comb in accordance with the aspect of the
present invention, the stepped part may be formed so as to be
exposed between the comb tooth and an adjacent comb tooth.
[0035] Further, in the comb in accordance with the aspect of the
present invention, the stepped part may be formed so as to be
exposed on a perimeter of the comb tooth, when the comb tooth is
seen in a direction corresponding to width directions of the comb
main body.
[0036] Furthermore, in the comb in accordance with the aspect of
the present invention, the stepped part may be formed slantly with
respect to the protruding direction so that the stepped part
spreads toward the root side of the comb tooth.
[0037] In the comb in accordance with the aspect of the present
invention, the first section may be formed in a tapered shape so
that the first section spreads from the tip end side toward the
stepped part.
[0038] Further, in the comb in accordance with the aspect of the
present invention, the second section may be formed in a tapered
shape so that the second section spreads from the stepped part
toward the root side.
[0039] Further, in the comb in accordance with the aspect of the
present invention, heights of the tip ends of three or more
adjacent comb teeth among the plurality of comb teeth may be
different from each other.
[0040] Furthermore, in the comb in accordance with the aspect of
the present invention, three or more tooth bottoms between adjacent
comb teeth among the plurality of comb teeth may be different from
each other in a tooth bottom depth.
[0041] In the comb in accordance with the aspect of the present
invention, a plurality of comb teeth where the stepped part is not
formed may be arrayed parallel to the row of the plurality of comb
teeth where the stepped part is formed. An interval of the comb
teeth where the stepped part is not formed may be wider than an
interval of the comb teeth where the stepped part is formed.
[0042] Further, in the comb in accordance with the aspect of the
present invention, rows of a plurality of comb teeth where the
stepped part is not formed may be formed parallel to and on both
sides of the row of the plurality of comb teeth where the stepped
part is formed. An interval of the comb teeth where the stepped
part is not formed may be wider than an interval of the comb teeth
where the stepped part is formed. Any of the plurality of comb
teeth where the stepped part is not formed may be formed at both
sides of any of the plurality of comb teeth where the stepped part
is formed.
[0043] In the comb in accordance with the aspect of the present
invention, the comb teeth where the stepped part is not formed may
be longer than the comb teeth where the stepped part is formed.
[0044] Further, in the comb in accordance with the aspect of the
present invention, the comb teeth where the stepped part is formed
may be longer than the comb teeth where the stepped part is not
formed.
[0045] Further, in the comb in accordance with the aspect of the
present invention, some of the plurality of comb teeth where the
stepped part is formed may be longer than the comb teeth where the
stepped part is not formed. Other comb teeth where the stepped part
is formed may be shorter than the comb teeth where the stepped part
is not formed.
[0046] Furthermore, in the comb in accordance with the aspect of
the present invention, the tooth bottom of the comb tooth where the
stepped part is formed may be formed so as to be convexed in a
center part of the comb main body in width directions thereof.
[0047] In accordance with the aspect of the present invention,
since each comb tooth is formed with the stepped part, and the
first section of each comb tooth that extends from the tip end side
to the stepped part has a smaller dimension in the direction
perpendicular to the protruding direction of the comb tooth,
compared with the second section that extends from the stepped part
to the root side, the stepped part is formed so as to be exposed on
the perimeter of the comb tooth at the intermediate position of the
comb tooth from the tip end side to the root side. Therefore, when
backcombing hair, the stepped part becomes a catching part against
the hair combed by the comb, and necessary resistance can be
obtained at the stepped part. Thus, the tension to the hair can be
increased throughout the entire comb to be higher than that with a
conventional comb, and backcombed hair can easily be formed.
[0048] In accordance with the aspect of the present invention,
since the stepped part is formed so as to be exposed between the
comb tooth and an adjacent comb tooth, the dimension of the
interval between the comb teeth changes in stages due to the
existence of the exposed stepped part. Therefore, when hair enters
between the comb teeth while backcombing hair, the resistance
against the hair changes accordingly, a degree of catching hair
increases, and the necessary tension can easily be obtained.
[0049] Further, in accordance with the aspect of the present
invention, the stepped part is formed so as to be exposed on the
perimeter of the comb tooth, when the comb tooth is seen in the
direction corresponding to the width directions of the comb main
body. Therefore, when backcombing hair, the hair is flowed in the
width directions of the comb main body along the perimeter of the
comb tooth, and then contacts the stepped parts. Thus, the
resistance against the hair when combing hair with the comb
increases, and the necessary tension can easily be obtained.
[0050] In accordance with the aspect of the present invention,
since the stepped part is formed slantly with respect to the
protruding direction, a situation such that hair is caught strongly
by the stepped part and the hair is damaged or the hair is cut can
be avoided. Moreover, when more than a certain degree of tension is
applied, the hair can be allowed to escape from the stepped part
formed slantly and then to the tooth bottom, and thus, backcombed
hair can be formed with care to the hair.
[0051] Further, in accordance with the aspect of the present
invention, since the first section which is formed from the tip end
side toward the stepped part of the comb tooth, or the second
section which is formed from the stepped part toward the root side,
is formed in a tapered shape, compared with a comb tooth formed in
a straight shape, the resistance against hair becomes stronger even
at the perimeter of the comb tooth itself which the hair contacts,
and thus, suitable tension required for backcombing hair can easily
be obtained.
[0052] In accordance with the aspect of the present invention,
since the heights of the tip ends of three or more adjacent comb
teeth are different from each other, when the comb is inserted into
hair from the tooth tips when backcombing hair, timings of the hair
contacting the tooth tips are different between the adjacent comb
teeth. Compared with parts where the tooth tips project more than
other parts, parts where the tooth tips project less than other
parts contact the hair at the tooth tips later, and thus, the
resistance becomes relatively low against hair contacting the parts
where the tooth tips are less projected. As a result, the
resistance against the hair at the tooth tips is dispersed, and
when backcombing hair, sweater-pill-like portions are generated
less within some part of the backcombed hair, and uniformly spread
backcombed hair can easily be formed without increasing density of
the hair. Note that in the present invention, the reason why the
number of teeth of which the heights of the tip ends differ is
limited to three or more adjacent comb teeth is that the degree of
dispersion of resistance by the tooth tips is not enough with two
adjacent comb teeth.
[0053] In accordance with the aspect of the present invention,
since three or more tooth bottoms between adjacent comb teeth are
different from each other in the tooth bottom depth, when
backcombing hair, timings of the hair contacting the tooth bottoms
are different between the adjacent comb teeth, and accordingly, a
degree of catching hair at the tooth bottoms is different from each
tooth bottom. In other words, a part of hair caught at the tooth
bottoms more convexed than other parts is caught strongly because
the tooth bottoms are protruding. This results in causing locally
strong and weak parts in the degree of catching hair at the tooth
bottoms of the comb, and suitable tension for backcombing hair can
be obtained mainly on the part of hair caught strongly, and thus,
backcombed hair can easily be set. Further, since the tooth bottoms
have more than three different depths, hair caught at the tooth
bottoms with intermediate bottom depths obtains an intermediate
degree of tension, and it mitigates a difference between the strong
and weak parts of the degree of catching at the most convexed tooth
bottoms and the most concaved tooth bottoms. Therefore, tangles of
hair due to the difference between the strong and weak parts of the
degree of catching are suppressed, and the comb can be moved
smoothly when backcombing hair.
[0054] In accordance with the aspect of the present invention,
since the plurality of comb teeth where the stepped part is not
formed are arrayed parallel to the row of the plurality of comb
teeth where the stepped part is formed, hair enters even between
the row of comb teeth where the stepped part is formed and the row
of comb teeth where the stepped part is not formed, and the
resistance against the hair can be increased. In addition, since
intervals between the comb teeth are different between the
respective rows, the degree of catching hair can be dispersed.
[0055] In accordance with the aspect of the present invention,
since rows of the plurality of comb teeth where the stepped part is
not formed are formed on both sides of the row of the plurality of
comb teeth where the stepped part is formed, hair enters even
between the row of comb teeth where the stepped part is formed and
the rows of comb teeth where the stepped part is not formed, and
the resistance against the hair can further be increased. In
addition, since the intervals between the comb teeth are different
between the respective rows, the degree of catching hair can be
dispersed.
[0056] In accordance with the aspect of the present invention,
since the comb teeth where the stepped part is not formed are
formed longer than the comb teeth where the stepped part is formed,
the tip ends of comb teeth where the stepped part is not formed is
located higher than the tip ends of comb teeth where the stepped
part is formed. Also, the comb teeth where the stepped part is not
formed have wide intervals between the comb teeth, and therefore,
the tip ends of the comb teeth where the stepped part is not formed
can be used as coarse teeth suited for parting the hair, rough
hairdressing, etc. Thus, the usability of the comb can be
widened.
[0057] In accordance with the aspect of the present invention,
since the comb teeth where the stepped part is formed are longer
than the comb teeth where the stepped part is not formed, the tip
ends of the comb teeth where the stepped part is formed are located
higher than the tip ends of the comb teeth where the stepped part
is not formed. Also, the comb teeth where the stepped part is
formed have narrow intervals between the comb teeth, and therefore,
the tip ends of the comb teeth where the stepped part is formed can
be used as so-called fine teeth to smooth down the surface of the
formed backcombed hair. The comb used to form backcombed hair can
be used as it is to smooth down the surface of the backcombed hair,
and thus, a series of procedures from forming backcombed hair to
hairdressing the surface of the backcombed hair can smoothly be
performed with one comb.
[0058] In accordance with the aspect of the present invention,
since some of the plurality of comb teeth where the stepped part is
formed are longer than the comb teeth where the stepped part is not
formed, and also other comb teeth where the stepped part is formed
are shorter than the comb teeth where the stepped part is not
formed, the comb has a range where the comb teeth can be used as
the so-called fine teeth, and a range where the comb teeth can be
used as the so-called coarse teeth. As a result, one comb can be
applied to the usage as the fine teeth and also to the usage as the
coarse teeth, and thus, a series of procedures from forming
backcombed hair to hairdressing can more smoothly be performed.
[0059] In accordance with the aspect of the present invention,
since the tooth bottom of the comb tooth, where the stepped part is
formed, is formed so as to be convexed in the center part of the
comb main body in width directions thereof, hair caught at the
tooth bottom contacts at the convexed center part of the tooth
bottom in a line contact or a point contact. Thus, contact pressure
of the hair against the tooth bottom is increased, the degree of
catching hair at the tooth bottom is increased more, and therefore,
backcombed hair can easily be formed, and damage to the hair by an
edge of the tooth bottom etc. can be reduced.
Effects of the Invention
[0060] In accordance with the aspect of the present invention,
since the stepped part is formed so as to be exposed on the
perimeter of the comb tooth, when backcombing hair, the hair combed
by the comb is caught at the stepped part and the necessary
resistance can be obtained. Thus, as an entire comb, the tension to
the hair can be increased to be higher than the conventional comb,
and the hair can suitably be backcombed.
[0061] In accordance with the aspect of the present invention,
since the stepped part is formed slantly with respect to the
protruding direction, it can be avoided that the hair is caught
strongly by the stepped part and damaged. Moreover, when more than
a certain degree of tension is applied to the hair, the hair is
allowed to escape from the stepped part formed slantly toward the
tooth bottom, and thus, backcombed hair can be formed with care to
the hair.
[0062] In accordance with the aspect of the present invention,
since the first section which is formed from the tip end side
toward the stepped part of the comb teeth, or the second section
which is formed from the stepped part toward the root side is
formed in a tapered shape, compared to comb teeth formed in a
straight shape, the resistance against the hair can be stronger,
even at the perimeters of the comb teeth themselves where the hair
contacts, and thus, the suitable tension required for backcombing
hair can be obtained.
[0063] In accordance with the aspect of the present invention,
since the heights of the tip ends are different from each other,
the resistance against the hair at the tooth tips is dispersed, and
when backcombing hair, it can be prevented that the
sweater-pill-like portions are generated within some part of the
backcombed hair, and uniformly spread backcombed hair can be formed
without increasing density of the hair.
[0064] In accordance with the aspect of the present invention,
since the tooth bottoms are different from each other in the tooth
bottom depth, when backcombing hair, the degree of catching hair at
the tooth bottoms can be different between respective tooth
bottoms, and thus, the suitable tension required for backcombing
hair can be obtained, and backcombed hair can uniformly be set.
[0065] In accordance with the aspect of the present invention,
since the plurality of comb teeth where the stepped part is not
formed are arrayed parallel to the row of the plurality of comb
teeth where the stepped part is formed, the resistance against the
hair can be increased. In addition, since the intervals between the
comb teeth are different between the respective rows, the degree of
catching hair is dispersed and backcombed hair can easily be
set.
[0066] In accordance with the aspect of the present invention,
since the comb teeth where the stepped part is not formed are
longer than the comb teeth where the stepped part is formed, the
tip ends of the comb teeth where the stepped part is not formed can
be used as the coarse teeth, and the usability of the comb can be
widened.
[0067] In accordance with the aspect of the present invention,
since the comb teeth where the stepped part is formed are longer
than the comb teeth where the stepped part is not formed, the tip
ends of the comb teeth where the stepped part is formed can be used
as the fine teeth, and the usability of the comb can be
widened.
[0068] In accordance with the aspect of the present invention,
since some of the plurality of comb teeth where the stepped part is
formed are longer than the comb teeth where the stepped part is not
formed, and other comb teeth where the stepped part is formed are
shorter than the comb teeth where the stepped part is not formed,
some range of the comb can be used as the dense teeth and another
range can be used as the coarse teeth. In addition to the usage of
backcombing hair, the comb can be used for other usages.
[0069] In accordance with the aspect of the present invention,
since the tooth bottom of the comb tooth, where the stepped part is
formed, is formed to be convexed in the center part of the comb
main body in the width directions thereof, hair caught at the tooth
bottom contacts the tooth bottom at the convexed center part in a
line contact or a point contact. Thus, the contact pressure of the
hair against the tooth bottom can be increased, and therefore, the
degree of catching hair at the tooth bottom is increased more, and
backcombed hair can easily be formed.

MODES FOR CARRYING OUT THE INVENTION
[0091] FIGS. 1 to 3 are schematic diagrams illustrating an overall
appearance of a comb 1 in accordance with one embodiment of the
present invention. The comb 1 of this embodiment is a type which is
called a "tail comb" having a shape in which a bar-shaped grip part
4 projects from a comb main body 2, and the comb 1 is made of a
synthetic resin in this embodiment. As illustrated in FIGS. 1, 3,
etc., the comb 1 is provided with a total of three rows of comb
teeth, in which outer comb teeth 7 and 8 are arrayed in parallel to
and on both sides of a row of the inner comb teeth 20, and the
inner comb teeth 20 etc. are formed in a characteristic shape.
Therefore, it is easy to backcomb hair. Hereinafter, the comb 1 of
this embodiment is described in detail. Note that an X-axis in FIG.
1 is an axis parallel to a longitudinal direction of the comb main
body 2 from which the pluralities of the outer comb teeth 7 and 8
and a plurality of inner comb teeth 20 are protruding (the X-axis
extends in the same direction as a longitudinal direction of the
bar-shaped grip part 4). Further, a Y-axis is an axis parallel to
width directions of the comb main body 2 (an axis which is
perpendicular to the X-axis described above), and a Z-axis is an
axis parallel to the protruding direction of the inner comb teeth
20 (an axis which is perpendicular to both the X-axis and the
Y-axis described above). The directions of the X-axis, the Y-axis,
and the Z-axis (X-axis direction, Y-axis direction, and Z-axis
direction) are similar in other drawings.
[0092] In the comb main body 2, pointed comb protecting parts 5a
and 5b are protruding in the Z-axis direction from a tip end part
2a and a rear end part 2b, respectively, of a bar-shaped portion
which extends in the X-axis direction. These comb protecting parts
5a and 5b are located so as to sandwich therebetween the
pluralities of outer comb teeth 7 and 8 and inner comb teeth 20
which are arrayed in the X-axis direction, and serve as protection
for the comb teeth 7, 8 and 20. In addition, in the comb main body
2, a plurality of through-holes 6 which penetrate the comb main
body 2 from one side surface 2c to the other side surface 2d
(penetrate in the Y-axis direction) are formed in the bar-shaped
portion, at a given interval in the X-axis direction. These
through-holes 6 have an elliptical shape in which their major axes
are parallel to the X-axis direction, and a counter bore in an
elliptically recessed shape is formed around each through-hole.
[0093] Further, the comb main body 2 is formed with a
triangular-shaped coupling part 3 at the rear end part 2b so that
the comb main body 2 is connected with the bar-shaped grip part 4.
In the coupling part 3, a grooved recessed portion 3a which extends
in the X-axis direction is formed, and raindrop-shaped
through-holes 3b and 3c are formed so as to be separated from the
recessed portion 3a in the Z-axis direction. Since these recessed
portion 3a and through-holes 3b and 3c are formed in the coupling
part 3, the rigidity of the coupling part 3 is reduced to allow
itself to be elastically bent. Thus, when a user, such as a
beautician, a barber, etc., uses the comb 1 and if he/she applies a
gripping force in such a way that he/she holds both the grip part 4
and the comb main body 2, the coupling part 3 is elastically curved
or bent so that the entire comb conforms to the user's hand.
[0094] Moreover, as illustrated in FIG. 3, both the side surfaces
2c and 2d of the comb main body 2 are formed in wavy surfaces
having a concavo-convex shape (the through-hole 6 is located at
each concave part) so that the wavy surfaces of the concave-convex
shape exhibit an anti-slip function for user's fingertips when the
user holds the comb main body 2 at the side surfaces 2c and 2d with
his/her fingers. Based on a similar reason, a back surface 2e of
the comb main body 2 (a surface opposite from the side where the
comb teeth 7, 8 and 20 are located) is formed in a wavy surface
having a concave-convex shape, and a perimeter of the coupling part
3 which continues from the comb main body 2 and a perimeter of the
grip part 4 are formed in concave-convex shapes, so that those
concave-convex shape parts exhibit the anti-slip function.
[0095] As illustrated in FIG. 5, in the comb main body 2, a
plurality of pin-like comb teeth 7 and 8 are protruding from an
upper surface 2f, and an interval of the comb teeth 7 and 8 is set
to a dimension P (a pitch dimension P). Note that, as a numerical
value example of the pitch dimension P, a value within a range from
about 3 mm to about 8 mm can be considered, and it is suitable to
set the value at about 5 mm in order to easily backcomb the hair.
In addition, as illustrated in FIG. 4, an elongated groove-like
slot portion 2g is formed in the comb main body 2 so as to extend
in the X-axis direction at a center part in width directions of the
comb main body 2. The inner comb teeth member 10 which is a
separate member from the inner comb teeth 20 and where the inner
comb teeth 20 are formed is inserted or fitted into the slot
portion 2g. A latching protrusion 2h for latching the inner comb
teeth member 10 projects from a back end side of the slot portion
2g. Note that the comb main body 2 in FIG. 4 is illustrated as a
cross-sectional shape taken along a line A-A in FIG. 3.
[0096] As illustrated in FIG. 4, the inner comb teeth member 10 is
a plate-like member as a whole, and a plurality of inner comb teeth
20 are protruding from an elongated-plate-like base part 11 of the
inner comb teeth member 10. A plurality of ellipse holes 12 (these
ellipse holes 12 penetrate the base part 11) are formed at a given
interval in the base part 11 from one end part 11c to the other end
part 11d. These ellipse holes 12 are aligned with the through-holes
6 of the comb main body 2 so that the ellipse holes 12 communicate
with the through-holes 6, respectively, when the inner comb teeth
member 10 is attached to the slot portion 2g of the comb main body
2. Ventilation is secured by the through-holes 6 which communicate
with the ellipse holes 12. Thus, if the user, such as a beautician,
a barber, etc., places his/her fingers on the side surface 2c (or
the other side surface 2d) of the comb main body 2, his/her
fingertips are guided to the through-holes 6 located at the concave
part because of the wavy surface having the concavo-convex shape of
the side surface 2c (or the other side surface 2d). Therefore, a
situation in which the comb is slippery with wet fingertips can be
improved because the fingertips placed on the side surface 2c (or
the other side surface 2d) can be exposed to open air via the
through-holes 6 to dry the fingertips faster even if the fingertips
are wet with moisture, chemical solutions, etc.
[0097] In addition, a plurality of elongated groove portions 13 are
formed in the base part 11 of the inner comb teeth member 10 at
three locations above the ellipse holes 12, respectively, so that
the inner comb teeth member 10 easily enters into the slot portion
2g of the comb main body 2. In addition, a latching recessed
portion 11e is formed in the other end part 11d of the inner comb
teeth member 10. When the inner comb teeth member 10 is fitted or
inserted into the slot portion 2g of the comb main body 2, the
locking projection 2h of the slot portion 2g is engaged with the
latching recessed portion 11e and the latching recessed portion 11e
functions as a stopper of the inner comb teeth member 10. Note that
a surface of an upper part 11b where the inner comb teeth 20
protrude and which is opposite from a back surface 11a of the base
part 11 of the inner comb teeth member 10, is formed in a zigzag
shape by differentiating bottom depths between the comb teeth in
the inner comb teeth 20 as will be described later.
[0098] FIG. 6 illustrates the plurality of the inner comb teeth 20
provided to the inner comb teeth member 10 in detail. The inner
comb teeth 20 of this embodiment have the inner comb teeth in a
total of three patterns: first inner comb teeth 30, second inner
comb teeth 40, and third inner comb teeth 50, of which tip end
heights are different from each other. One of the first inner comb
teeth 30, one of the second inner comb teeth 40, and one of the
third inner comb teeth 50, which continue sequentially and are
adjacent to each other, constitute one comb teeth group as a group
unit. Thus, the inner comb teeth 20 are an aggregate of such comb
teeth groups where a plurality of comb teeth groups are arrayed in
the X-axis direction. Note that FIG. 6 illustrates the inner comb
teeth 20, seen in a direction parallel to the Y-axis direction (a
direction when the side surface 2c of the comb main body 2 is seen
from a front elevational view).
[0099] Among the first inner comb tooth 30, the second inner comb
tooth 40, and the third inner comb tooth 50, the third inner comb
tooth 50 has the highest tip position. The second inner comb tooth
40 has the second highest tip position (a tip end 40a of the second
inner comb tooth 40 is lower than a tip end 50a of the third inner
comb tooth 50 by a height dimension h2). The first inner comb tooth
30 has the lowest tip position (a tip end 30a of the first inner
comb tooth 30 is lower than the tip end 40a of the second inner
comb teeth 40 by a height dimension h1). As numerical value
examples of the height dimensions h1 and h2, values within a range
from about 1 mm to about 3 mm can be considered, and about 1 mm is
preferred because it is easy to form the uniform backcombed
hair.
[0100] Note that, as illustrated in FIG. 5, in a state where the
inner comb teeth member 10 is inserted or fitted into the comb main
body 2, even the third inner comb teeth 50 with the highest tip
position are lower than the outer comb teeth 7 (the outer comb
teeth 8) by a height dimension H (a dimension from a tip end 7a of
the outer comb tooth 7 to the tip end 50a of the third inner comb
tooth 50). Thus, the outer comb teeth 7 (the outer comb teeth 8)
are longer than the inner comb teeth 20, and since the inner comb
teeth 20 (the first inner comb teeth 30, the second inner comb
teeth 40, and the third inner comb teeth 50) do not exist within a
range of the height dimension H from the tip end side thereof, it
is possible to use the outer comb teeth 7 (the outer comb teeth 8)
of the comb 1 within a range of the height dimension H from the tip
end side as coarse teeth with the pitch dimension P, and the parts
of the outer comb teeth 7 (the outer comb teeth 8) can be used for
parting the hair, rough hairdressing, etc. Note that, as a
numerical value example of the height dimension H, a value within a
range from about 3 mm to about 10 mm can be considered, and about 5
mm is preferred because this makes the comb easy to use.
[0101] Further, as illustrated in FIG. 6, a stepped part 32 is
formed at an intermediate position of the first inner comb tooth 30
in the comb tooth protruding direction (the Z-axis direction) which
is the longitudinal direction of the first inner comb tooth 30. The
stepped part 32 is formed so that its thickness dimension (a
dimension parallel to the X-axis direction) increases toward the
root side (the base part 11 side which is an origin of protrusion)
and its perimeter becomes diagonal. As the result, the stepped part
32 has a trapezoidal shape as a whole. Such a perimeter side of the
stepped part 32 seen in a direction parallel to the Y-axis
direction (the direction when the side surface 2c of the comb main
body 2 is seen from the front elevational view) is exposed between
the adjacent second inner comb teeth 40 (between the comb
teeth).
[0102] In addition, the first inner comb tooth 30 has a first
section 31 ranging from the tip end 30a to an upper end 32a of the
stepped part 32, and a second section 33 ranging from a lower end
32b of the stepped part 32 to a root 30b (a protrusion base part of
the upper part 11b of the base part 11). The first section 31 is
formed in a tapered shape so that a thickness dimension thereof
parallel to the X-axis direction spreads from the tip end 30a to
the stepped part 32 (a dimension in a direction perpendicular to
the protruding direction of the first inner comb tooth 30). To be
more specific, assuming that a thickness dimension on the tip end
30a side is w1 and a thickness dimension on the upper end 32a side
of the stepped part 32 is w2, a relation of w1<w2 is satisfied.
Similarly, the second section 33 is formed in a tapered shape so
that a thickness dimension parallel to the X-axis direction spreads
from the lower end 32b of the stepped part 32 to the root 30b. To
be more specific, assuming that a thickness dimension of the lower
end 32b of the stepped part 32 is w3 and a thickness dimension on
the root 30b side is w4, a relation of w3<w4 is satisfied (a
numerical value example of w4 can be considered to be a value
within a range from about 0.8 mm to about 2.0 mm). Note that since
the entire stepped part 32 has the trapezoidal shape as described
above, the thickness dimension w2 at the lower side of the first
section 31 is smaller than the thickness dimension w3 at the upper
side of the second section 33 (w2<w3).
[0103] Stepped parts etc. of the second inner comb teeth 40 and the
third inner comb teeth 50 basically have an equivalent structure to
the first inner comb teeth 30 described above. That is, stepped
parts 42 and 52 of a trapezoidal shape are formed at an
intermediate position in the comb teeth protruding direction (the
Z-axis direction), respectively, and sections from tip ends 40a and
50a to upper ends 42a and 52a of the stepped parts 42 and 52 are
first sections 41 and 51 of a tapered shape, respectively. Sections
from lower ends 42b and 52b of the stepped parts 42 and 52 to roots
40b and 50b are second sections 43 and 53 of a tapered shape,
respectively. Note that although the inner comb teeth 30, 40, and
50 are differentiated from each other in their heights of the tip
ends 30a, 40a, and 50a, respectively, as described above, the
heights of the stepped parts 32, 42, and 52 in the inner comb teeth
30, 40, and 50 are the same.
[0104] The intervals (pitch dimensions) of the adjacent inner comb
teeth 30, 40, and 50 are the same in this embodiment. Specifically,
if the pitch dimension between the first inner comb tooth 30 and
the second inner comb tooth 40 is p1, the pitch dimension between
the second inner comb tooth 40 and the third inner comb tooth 50 is
p2, and the pitch dimension between the third inner comb tooth 50
and another first inner comb tooth 30 which constitutes the
subsequent comb teeth group is p3, a relation of p1=p2=p3 is
satisfied. Since the inner comb teeth 30, 40, and 50 have the shape
as described above, gap dimensions between the comb teeth varies
depending on locations in the protruding direction (the Z-axis
direction) of the inner comb teeth 30, 40, and 50, even if the
intervals of the inner comb teeth 30, 40, and 50 are p1=p2=p3. Note
that, as specific numerical value examples of p1, p2, and p3,
values within a range from about 0.7 mm to about 2 mm can be
considered, and about 1 mm is preferred because this makes it easy
to backcomb the hair.
[0105] As illustrated in FIG. 6, for example, a gap between the
third inner comb tooth 50 and the first inner comb tooth 30 which
constitutes the subsequent comb teeth group is w5, as the gap
dimension at the tip end of the first inner comb tooth 30. However,
since the first sections 31 and 51 have the tapered shape,
respectively, a gap dimension w6 at the upper end 52a of the
stepped part 52 is narrower than the gap dimension w5 (w6<w5).
Further, a gap dimension at the lower end 52b of the stepped part
52 is narrower so that a relation of [the gap dimension w7<the
gap dimension w6] is satisfied since the stepped parts 32 and 52
have the trapezoidal shape, respectively. Further, a gap dimension
at the root 50b is further narrower so that a relation of [the gap
dimension w8<the gap dimension w7] is satisfied since the second
sections 33 and 53 have the tapered shape, respectively. Note that,
as a numerical value example of the gap dimension w6, a value
within a range from about 0.8 mm to about 1.2 mm can be considered,
and as a numerical value example of the gap dimension w7, a value
within a range from about 0.3 mm to about 0.7 mm can be considered.
As described above, the gap between the third inner comb teeth 50
and the first inner comb teeth 30 which constitutes the subsequent
comb teeth group is narrower in the gap dimension toward the tooth
bottom, and moreover, since the stepped parts 32 and 52 of the
trapezoidal shape exist at the intermediate locations, the gap
dimension does not become narrower constantly, but the gap
dimension becomes narrower suddenly at the locations corresponding
to the stepped parts 32 and 52. Therefore, when the hair enters
between the third inner comb teeth 50 and the first inner comb
teeth 30, the gap acts as friction or resistance to achieve the
necessary tension in the hair. Such a condition of variation in the
gap dimension between the comb teeth is similarly applied to the
gap between the first inner comb teeth 30 and the second inner comb
teeth 40, and the gap between the second inner comb teeth 40 and
the third inner comb teeth 50.
[0106] Further, the bottom depths at the gaps between the
respective inner comb teeth 30, 40, and 50, which continue and are
adjacent to each other, are differentiated, similar to the tip end
heights described above. For example, a first tooth bottom 25 at
the gap between the third inner comb teeth 50 and the first inner
comb teeth 30 which constitutes the subsequent comb teeth group is
the deepest. The second deepest is a second tooth bottom 26 at the
gap between the first inner comb teeth 30 and the second inner comb
teeth 40. A third tooth bottom 27 at the gap between the second
inner comb teeth 40 and the third inner comb teeth 50 is the
shallowest and is located higher by a height dimension h3 than the
first tooth bottom 25 which is the deepest. The third tooth bottom
27 is located higher by a height dimension h4 than the second deep
bottom 26 which is the second deepest. Note that numerical value
examples of the height dimensions h3 and h4 are about the same as
the height dimensions h1 and h2 described above.
[0107] FIG. 7 illustrates a cross section taken along a line B-B in
FIG. 6, and illustrates a state in which the first inner comb tooth
30 is seen from the tip end side of the comb main body 2 (a diagram
seen in a direction parallel to the X-axis direction). Even when it
is seen in this direction, the first inner comb tooth 30 is formed
so that the stepped part 32 is exposed on the perimeter at the
intermediate position in the comb teeth protruding direction (the
Z-axis direction), and even when it is seen in the direction
illustrated in FIG. 7, the perimeter side of the stepped part 32 is
formed slantly (the stepped part 32 is also formed in the
trapezoidal shape when seen in the direction illustrated in FIG. 7)
so that the width dimension (the dimension parallel to the Y-axis
direction) increases toward the root side, similar to the case
illustrated in FIG. 6.
[0108] Further, even when it is seen in the direction illustrated
in FIG. 7, the first inner comb tooth 30 is formed in the tapered
shape within the first section 31 from the tip end 30a to the upper
end 32a of the stepped part 32. The first inner comb tooth 30 is
also formed in the tapered shape, even when it is seen in the
direction illustrated in FIG. 7, within the second section 33 from
the lower end 32b of the stepped part 32 to the root 30b side.
According to such a shape, if it is assumed that a width dimension
on the tip end 30a side of the first inner comb tooth 30 when it is
seen in the direction illustrated in FIG. 7 is w10, and a width
dimension on the upper end 32a side of the stepped part 32 is w11,
a relation of w11>w10 is satisfied. As for the second section
33, if it is assumed that a width dimension on the lower end 32b of
the stepped part 32 is w12 (w12>w11) and a width dimension on
the root side is w13, a relation of w13>w12 is satisfied (as a
numerical value example of w13, a value within a range from about
1.5 mm to about 2.5 mm can be considered). The shapes of the second
inner comb teeth 40 and the third inner comb teeth 50 are about the
same as the shape of the first inner comb teeth 30 when seen in the
direction illustrated in FIG. 7 as described above. Note that
although the outer comb teeth 7 and 8 where no stepped part is
formed are illustrated by lines formed by alternating one long and
two short dashes in FIG. 7, the outer comb teeth 7 and 8 are
located at positions separated from the inner comb teeth 20 (the
first inner comb teeth 30, the second inner comb teeth 40, and the
third inner comb teeth 50) described above by a given gap.
[0109] Further, as illustrated in FIG. 7, the first tooth bottom 25
at the gap between the third inner comb tooth 50 and the first
inner comb tooth 30 together have a chevron shape as a whole. More
specifically, the first tooth bottom 25 is formed in a convex shape
so that a center part 25a in the width directions of the comb main
body 2 (Y-axis direction) is curved and protrudes the most, and
both side parts 25b and 25c of the center part 25a are concavely
curved. The shapes of the other second tooth bottom 26 and third
tooth bottom 27 are similar to the shape of the first tooth bottom
25 described above. Thus, since the tooth bottoms 25 to 27 have the
curved peripheral shapes at various locations, the hair which is
caught by the first tooth bottoms 25 is made difficult to contact
corner(s) of the upper part 11b in the base part 11 of the inner
comb teeth member 10. Therefore, the hair will not be damaged more
than necessary when backcombing the hair.
[0110] FIGS. 1 to 3, and 5 illustrate a state in which the base
part 11 of the inner comb tooth member 10 which is provided with
the inner comb teeth 20 described above is inserted or fitted into
the slot portion 2g of the comb main body 2. Since the base part 11
is inserted or fitted in this way, the base part 11 of the inner
comb teeth member 10 becomes integral with the comb main body 2.
Therefore, the inner comb teeth 20 of the inner comb teeth member
10 also protrude from the comb main body 2, and the row of the
inner comb teeth 20 and the rows of the outer comb teeth 7 and 8
are parallel to the X-axis direction (refer to FIG. 3). Note that,
in the state in which the inner comb teeth member 10 is inserted or
fitted into the comb main body 2 and becomes integral with the comb
main body 2, the first tooth bottoms 25 which are formed the
deepest in the inner comb teeth 20 are disposed higher in the
Z-axis direction than the upper surface 2f of the comb main body 2,
and thereby, when backcombing the hair, the first tooth bottoms 25
at the deepest position can also contact the hair easily to apply
the tension to the hair, as illustrated in FIG. 5 etc.
[0111] Further, the interval between the outer comb teeth 7 and 8
where the stepped parts are not formed (the pitch dimension P
illustrated in FIG. 5) differs from the interval between the inner
comb teeth 20 illustrated in FIG. 6 (the pitch dimensions p1, p2,
and p3), and the pitch dimension P of the outer comb teeth 7 and 8
is wider than the pitch dimensions p1, p2, and p3 of the inner comb
teeth 20 (P>p1, p2, and p3). According to the difference between
the pitch dimension P and the pitch dimensions p1, p2, and p3, when
the inner comb teeth member 10 is inserted into the comb main body
2, some of the plurality of inner comb teeth 20 are sandwiched from
both sides by either the outer comb teeth 7 or the outer comb teeth
8. For example, in FIG. 5, the second one among the first inner
comb teeth 30 and the third one among the second inner comb teeth
40 when counted from the comb protecting part 5a which is located
on the tip end side of the comb 1 (from the left in FIG. 5) are
sandwiched by the outer comb teeth 7 and the outer comb teeth
8.
[0112] Next, as illustrated in FIG. 19, a situation when
backcombing the hair using the comb 1 having the structure
described above is described. First, when the comb 1 is inserted
into a bundle of hair of a given volume which is extracted and held
up from the rest of the hair, the hair enters into respective
intervals between the outer comb teeth 7, 8 and the inner comb
teeth 20.
[0113] FIG. 9 illustrates a situation in which hair Hr enters into
respective intervals between the inner comb teeth 20 (the first
inner comb teeth 30, the second inner comb teeth 40, and the third
inner comb teeth 50). Note that the hair Hr illustrated in FIG. 9
is illustrated as a circular cross-sectional shape.
[0114] When the comb 1 is inserted into the hair bundle, the hair
Hr contacts each of the tip ends 30a, 40a, and 50a of the first
inner comb teeth 30, the second inner comb teeth 40, and the third
inner comb teeth 50. However, since the heights of the tip ends
30a, 40a, and 50a are different from each other as described above,
the tip end 50a of the third inner comb teeth 50 which is located
the highest tends to contact the hair Hr first. Thus, since the
situations (timings) of the hair contacting the tip ends 30a, 40a,
and 50a differ for the inner comb teeth 30, 40, and 50, the
contacting situations to the inner comb teeth 30, 40, and 50 are
dispersed. Therefore, the hair which can be backcombed becomes
uniform, and sweater-pill-like portions are generated less within
the backcombed hair.
[0115] Next, a situation in which the hair Hr enters into
respective intervals between the inner comb teeth 20, 30, and 50 is
described. As described above, since the first sections 31, 41, and
51 are formed in the tapered shape, the intervals between the tip
ends are quite larger than the intervals between the tooth bottoms.
Therefore, the hair Hr easily enters into intervals between the
comb teeth smoothly.
[0116] Since among the hair Hr entered in intervals between the
comb teeth, some of the hair Hr which enters along the inner comb
teeth 20, 30, and 50 moves along the first sections 31, 41, and 51
of the tapered shape, certain levels of resistance can be obtained.
Further, the hair Hr which has moved along the first sections 31,
41, and 51 then moves to the stepped parts 32, 42, and 52. However,
since the stepped parts 32, 42, and 52 have different angles from
the first sections 31, 41, and 51, high resistance can be obtained
when the hair enters into the ranges of the stepped parts 32, 42,
and 52. Therefore, the tension required for backcombing the hair
can be obtained. Further, since the stepped parts 32, 42, and 52
have the trapezoidal shape as described above, the hair Hr which
moves along the stepped parts 32, 42, and 52 receives resistance
stronger than the resistance at the first sections 31, 41, and 51
of the tapered shape described above.
[0117] Further, the hair Hr which has moved along the stepped parts
32, 42, and 52 then moves toward the second sections 33, 43, and
53. However, since the intervals between the comb teeth in the
second sections 33, 43, and 53 are narrower than the intervals at
the tip ends 30a, 40a, and 50a described above, resistance by
pressure which is caused by the narrow intervals can be obtained.
Since the second sections 33, 43, and 53 are also formed in the
tapered shape, a certain level of resistance can be obtained in the
hair Hr which moves toward the tooth bottoms along the second
sections 33, 43, and 53. In addition, since the interval dimensions
between the comb teeth in the second sections 33, 43, and 53 are
narrower toward the tooth bottoms, resistance which is caused by
increasing the density of the hair Hr can also be obtained
according to the narrowing dimensions. Further, when the hair Hr
which has moved to the tooth bottoms 25, 26, and 27 increases, the
hair Hr is deposited at each tooth bottom part, and thus,
resistance by increasing the hair density can be obtained. Note
that quantities of the hair Hr which are deposited between the comb
teeth in the second sections 33, 43, and 53 differ from each other
because the depths of the tooth bottoms 25, 26, and 27 also differ
from each other as described above, and the resistance between the
comb teeth in the second sections 33, 43, and 53 varies
accordingly. Therefore, the backcombed hair formed becomes uniform,
and sweater-pill-like portions are generated less within the
backcombed hair.
[0118] Further, FIG. 10 illustrates the contacting situation of
hair Hr4 at the first tooth bottom 25. As described above, the
first tooth bottom 25 protrudes so as to have a peak at the center
part 25a while both the side parts 25b and 25c are dented.
Therefore, the hair Hr4 which enters into the first tooth bottom 25
mainly comes to contact with the first tooth bottom 25 at the
protruding center part 25a. Thus, the hair Hr4 contacts the first
tooth bottom 25 in not a surface contact but a line contact or a
point contact, and a contacting area is smaller than the surface
contact. Accordingly, the contact pressure can be increased and a
strong tension is applicable to the hair Hr4 which is in contact
with the first tooth bottom 25. Further, since the center part 25a
protrudes in the curved shape, it does not cause damage to the hair
due to the tension. Further, since both the side parts 25b and 25c
are dented, both the corners of the upper part of the base part 11
will not cause damage to the hair Hr4. Such a situation for the
hair at the first tooth bottom 25 is similar for the other second
tooth bottom 26 and third tooth bottom 27.
[0119] Note that, as illustrated in FIG. 10, the first inner comb
teeth 30 have the peripheral shape in which the first section 31
and the second section 33 are formed in the tapered shapes, similar
to the case in which they are seen in the direction parallel to the
Y-axis direction illustrated in FIG. 9 even when they are seen in
the direction parallel to the X-axis direction. In addition, the
stepped parts 32 are formed in the trapezoidal shape. Therefore, a
given level of resistance can be obtained against the hair which
contacts the first inner comb teeth 30 and moves toward the tooth
bottoms. Further, when the first inner comb teeth 30 are seen in
the direction parallel to the X-axis direction, the outer comb
teeth 7 and 8 are located on both sides of the first inner comb
teeth 30. Thus, even in the gap between the first inner comb teeth
30 and the outer comb teeth 7, or the gap between the first inner
comb teeth 30 and the outer comb teeth 8, a given level of
resistance can be obtained also at the gaps between the first inner
comb teeth 30 and the outer comb teeth 7 and 8 because the first
inner comb teeth 30 have the shape described above and the width
dimension of the gap becomes narrower as it goes toward the tooth
bottom. Situations at the gaps between the second inner comb teeth
40 and the outer comb teeth 7 and 8, or the gaps between the third
inner comb teeth 50 and the outer comb teeth 7 and 8, are similar
to the situation at the gaps between the first inner comb teeth 30
and the outer comb teeth 7 and 8.
[0120] Further, FIG. 8 illustrates a situation in which hair Hr1 to
3 enter into the gaps between the inner comb teeth 20 and the outer
comb teeth 7 and 8 so as to transverse the inner comb teeth 20 and
the outer comb teeth 7 and 8. FIG. 8 illustrates a situation in
which the hair Hr1 enters into the gap on the right side in FIG. 8
of the outer comb teeth 7 and 8 parallel to the Y-axis direction.
In such a case, the hair Hr1 is pinched linearly between the inner
comb tooth 20 which is located immediately on the right side of the
outer comb teeth 7 and 8 in the X-axis direction. Further, the hair
Hr2 enters into one of the places where the outer comb teeth 7 and
8 are located on both sides of the inner comb tooth 20 in the
direction parallel to the Y-axis direction. Therefore, the hair Hr2
is bent by the inner comb tooth 20 and is pinched by the inner comb
tooth 20 and the outer comb tooth 7 or 8, and strong resistance can
be obtained accordingly. Further, also in a situation in which the
inner comb tooth 20 does not exist between the outer comb teeth 7
and 8, since a situation in which hair Hr3 is bent is produced as
well, the given level of resistance can be obtained because the
inner comb tooth 20 is located at a location adjacent to the outer
comb teeth 7 and 8 in the X-axis direction.
[0121] As described above, since the comb 1 in accordance with this
embodiment devises the shape which produces the given level of
resistance at various locations, the comb 1 can give the hair a
suitable tension as a whole when backcombing the hair. Therefore,
it is easy to backcomb the hair. Further, in the comb 1 of this
embodiment, there are three different patterns of the tip end
heights of the inner comb teeth 20 and the depths of the tooth
bottoms. Thus, since variations in the resistance feel are created,
the uniform backcombed hair can be formed while preventing parts
where the hair is curled like pills from being created within the
backcombed hair by the concentrated resistance. Moreover, if
suitable tension is secured as described above, since the stepped
parts 32, 42, and 52 are formed in the shapes in which their
perimeters are open, situations in which the hair is damaged at
sharp parts like the edges, and the hair is caught by the stepped
parts 32, 42, and 52 and is damaged or torn off, do not occur. Note
that the comb in accordance with the present invention is not
limited to the embodiment described above but various modifications
can be considered.
[0122] For example, although all the pitch dimensions p1, p2, and
p3 of the adjacent inner comb teeth 30, 40, and 50 of the inner
comb teeth 20 are the same in the description related to FIG. 6, it
is also possible to have dimensions different from each other. For
example, the relation of the pitch dimensions may be set as
p1<p2<p3 so that the pitch dimension p1 between the first
inner comb tooth 30 and the second inner comb tooth 40 is the
narrowest, the pitch dimension p2 between the second inner comb
tooth 40 and the third inner comb tooth 50 is the second narrowest,
and the pitch dimension p3 between the third inner comb tooth 50
and the first inner comb teeth 30 which constitutes the subsequent
comb teeth group is the widest. Thus, since the pitch dimensions
are different from each other, the resistance between the comb
teeth at the narrowest pitch dimension p1 is the highest when
backcombing. The resistance between the comb teeth at the pitch
dimension p2 is the second highest, and the resistance between the
comb teeth at the pitch dimension p3 is lower than others.
Therefore, the resistance is suitably dispersed by the difference
in the pitch dimension between the inner comb teeth 20 as a whole,
and it is useful to form the uniform backcombed hair. Note that a
variation of the different pitch dimensions may include
p1>p2>p3, in addition to p1<p2<p3. In such a case, the
levels of resistance between the respective comb teeth are in a
reversed order from the case described above.
[0123] Further, according to the previous description, as for the
shape of the inner comb tooth 20, the stepped part 32 when the
inner comb tooth 20 (the first inner comb tooth 30) is seen in the
direction parallel to the Y-axis direction illustrated in FIG. 6
and the stepped part 32 when the inner comb tooth 20 (the first
inner comb tooth 30) is seen in the direction parallel to the
X-axis direction illustrated in FIG. 7 are formed at the same
position in a direction parallel to the Z-axis direction (the
protruding direction of the inner comb tooth 20), and both the
stepped parts 32 in respective directions are continuously integral
in all directions. Alternatively, the stepped part 32 (the first
stepped part) in the direction illustrated in FIG. 6 and the
stepped part 32 (the second stepped part) in the direction
illustrated in FIG. 7 are formed at different positions in the
direction parallel to the Z-axis direction so that these stepped
parts 32 are exposed respectively on the perimeter of the inner
comb tooth (the first inner comb tooth 30) as separate parts from
each other. As constructed in such a way, the resistance caused by
the stepped parts (the first stepped part and the second stepped
part) in the respective directions occurs at different positions in
the Z-axis direction, between the direction parallel to the Y-axis
direction illustrated in FIG. 6 and the direction parallel to the
X-axis direction illustrated in FIG. 7. Therefore, multi-stage
friction can be obtained against the hair bundle. Alternatively,
each stepped part 32 may be formed so as to be revealed on the
perimeter of the comb tooth only either when the inner comb tooth
20 (the first inner comb tooth 30) is seen in the direction
parallel to the Y-axis direction illustrated in FIG. 6, or when the
inner comb tooth 20 (the first inner comb tooth 30) is seen in the
direction parallel to the X-axis direction illustrated in FIG. 7.
Therefore, the shape of the comb teeth can be simplified.
[0124] FIG. 11(a) illustrates inner comb teeth (a first inner comb
teeth 130, a second inner comb teeth 140, a third inner comb teeth
150) of a modification. Unlike the inner comb teeth 20 illustrated
in FIG. 6, these inner comb teeth 130, 140, and 150 are
characterized by being constructed so that first sections 131, 141,
and 150 on the tip end 130a, 140a, and 150a sides and second
sections 133, 143, and 153 on root 130b, 140b, and 150b sides are
not formed in the tapered shapes, and their thickness dimensions
(in the direction parallel to the X-axis direction) are constant.
In addition, the oblique angles at the perimeter side of stepped
parts 132, 142, and 153 are further increased (tilted to increase
the angles with respect to the Z-axis).
[0125] Since the thickness dimensions of the first sections 131,
141, and 150 are constant, it is advantageous that projecting
amounts of the stepped parts 132, 142, and 153 increase, and when
the comb is inserted into the hair bundle, the resistance caused by
the stepped parts 132, 142, and 153 against the hair which moves
along the first sections 131, 141, and 150 increases. Further,
since the thickness dimensions of the second sections 133, 143, and
153 are constant, the hair which enters between the respective comb
teeth can be smoothly led to tooth bottoms 125, 126, and 127 on
respective root 130b, 140b, and 150b sides of the inner comb teeth
130, 140, and 150, and it is easy to obtain tension produced by the
tooth bottoms 125, 126, and 127, respectively.
[0126] Note that the constant thickness dimension of each section
illustrated in FIG. 11(a) may also be applied to only one of the
first sections 131, 141, and 150 or the second sections 133, 143,
and 153. For example, the first sections 131, 141, and 150 on the
tip ends 130a, 140a, and 150a sides may be formed to have the
constant thickness dimensions as illustrated in FIG. 11(a), while
the second sections 133, 143, and 153 may be formed in the tapered
shapes as illustrated in FIG. 6. Alternatively, in a reversed
manner, the first sections 131, 141, and 151 may be formed in the
tapered shapes as illustrated in FIG. 6, while the second sections
133, 143, and 153 may have the constant thickness dimensions as
illustrated in FIG. 11(a).
[0127] FIG. 11(b) illustrates the inner comb tooth (the first inner
comb tooth 130) of the modification related to FIG. 11(a) described
above. Also, when it is seen in the direction parallel to the
X-axis direction, the first section 131 on the tip end 130a side
and the second section 133 on the root 130b side are not formed in
the tapered shapes, and their thickness dimensions are constant,
similar to the case when seen in the direction parallel to the
Y-axis direction of FIG. 11(a). Thus, since the thickness
dimensions are also constant in the direction illustrated in FIG.
11(b), a similar advantage to the structure illustrated in FIG.
11(a) can be obtained. Although in FIG. 11(b), the case in which
the thickness dimensions of both the first section 131 and the
second section 133 are constant is illustrated, either the first
section 131 or the second section 133 may be formed in the tapered
shape, similar to the case of FIG. 11(a) described above. Note
that, of course, the structures related to FIGS. 11(a) and (b)
described above are also applicable to the second inner comb teeth
140 and the third inner comb teeth 150 which are other inner comb
teeth.
[0128] FIG. 12(a) illustrates an inner comb tooth (the first inner
comb tooth 230) of another modification when seen in the direction
parallel to the Y-axis direction, and illustrates the shape when a
plurality of stepped parts 232 and 235 are provided. In other
words, the first inner comb tooth 230 is sequentially provided with
a first section 231, the first stepped part 232, a second section
236, the second stepped part 235, and a third section 233 from a
tip end 230a side to a root 230b side. In this modification, since
the two stepped parts (the first stepped part 232 and the second
stepped part 235) are provided, it is advantageous in that the
friction which is obtained by the stepped parts can be doubled
compared with the case illustrated in FIGS. 6 and 11. Although FIG.
12(a) illustrates one example in which the two stepped parts 232
and 235 are provided, three or more stepped parts may also be
provided. Further, although FIG. 12(a) illustrates the case in
which thickness dimensions of all the sections 231, 233 and 236 are
constant, any one or two of the sections 231, 233, and 236 may also
be formed in the tapered shapes, similar to the case of FIG. 11(a)
described above. Note that the structure related to FIG. 12(a)
described above is also applicable to the second and third inner
comb teeth which are other inner comb teeth.
[0129] FIG. 12(b) illustrates an inner comb tooth (the first inner
comb tooth 230) of a modification related to FIG. 12(a) described
above. Also, when the inner comb tooth is seen in a direction
parallel to the X-axis direction, FIG. 12(b) illustrates the shape
where two stepped parts (the first stepped part 232 and the second
stepped part 235) are provided, similar to the case in which it is
seen in the direction parallel to the Y-axis direction of FIG.
12(a), and it is advantageous also in this case in that the
friction which is obtained by the stepped parts can be doubled.
Note that the elements illustrated in FIG. 12(a) described above
are also similarly applicable to the case illustrated in FIG.
12(b).
[0130] FIGS. 13(a) to (c) illustrate various modifications of the
tip end heights of the inner comb teeth. FIG. 13(a) illustrates one
example in which the number of comb teeth having different tip end
heights which are included in one comb teeth group is not three, as
illustrated in FIG. 6 etc., but four. In other words, in the
example of FIG. 13(a), one comb teeth group includes a total of
four comb teeth: an inner comb tooth having a tip end 20A located
the lowest, an inner comb tooth having a tip end 20B located the
third highest, an inner comb teeth having a tip end 20C located the
second highest, and an inner comb tooth having a tip end 20D
located the highest. A plurality of such comb teeth groups are
arrayed sequentially in a direction illustrated by an arrow in the
X-axis direction. Thus, since the comb teeth group is constituted
by a total of four inner comb teeth which have different tip end
heights, a difference in the resistance which is produced by the
difference in the tip end height can further be dispersed, and it
becomes even easier to form the uniform backcombed hair. Although
in FIG. 13(a) one example in which one comb teeth group is formed
by the total of four inner comb teeth is described, one comb teeth
group may also, of course, be formed by a total of five or more
inner comb teeth. The difference in the resistance can further be
dispersed by increasing the number of comb teeth having the
different tip end heights which constitute the comb teeth group.
The modifications illustrated in FIGS. 11, 12, etc. described above
are also applicable to the case illustrated in FIG. 13(a).
[0131] FIG. 13(b) illustrates a modification in which the arrayed
order of the inner comb teeth having the different tip end heights
is reversed, compared with the cases illustrated in FIG. 6, etc. In
other words, in the example of FIG. 13(b), one comb teeth group
includes, from the left in the drawing, an inner comb tooth having
a tip end 20C located the highest, an inner comb tooth having a tip
end 20B located the second highest, and an inner comb tooth having
a tip end 20A located the lowest. A plurality of such comb teeth
groups are sequentially arrayed in the direction illustrated by an
arrow in the X-axis direction. Such an arrayed order is suitable
because the friction on the comb tip end side which is an opposite
from the side where the bar-shaped grip part is provided in the
X-axis direction can be entirely increased. In other words, since
the comb tip end side (equivalent to the tip end side of the comb
main body) is the side apart from the grip part, the user's holding
force is generally difficult to be transmitted to the comb tip end
side. However, since the arrayed order as illustrated in FIG. 13(b)
is adopted so that the friction on the comb tip end side is
increased, the user can sense a suitable resistance of the entire
comb also at the comb tip end side in an actual use scenario.
Therefore, when backcombing the hair, uniform tension can be sensed
by the user through the entire comb, and a suitable feel can be
obtained when backcombing the hair. Note that the example in which
the four or more inner comb teeth having the different tip end
heights constitute one comb teeth group as illustrated in FIG.
13(a) described above can also be applied to the case illustrated
in FIG. 13(b), and further, the modifications illustrated in FIGS.
11, 12, etc. described above are also applicable thereto.
[0132] FIG. 13(c) illustrates a modification in which the arrayed
order of the inner comb teeth having the different tip end heights
is random, compared with the case illustrated in FIG. 6, etc. In
other words, the example of FIG. 13(c) includes an inner comb tooth
having a tip end 20A located the lowest, an inner comb tooth having
a tip end 20B located the second highest, and an inner comb tooth
having a tip end 20C located the highest, and it is characterized
by the fact that the arrayed order of these comb teeth is random
(irregular). Thus, since the arrayed order of the tip end heights
is random, friction produced by the hair contacting tip ends 20A,
20B, and 20C of the inner comb teeth also becomes random.
Therefore, it is advantageous in that the resistance obtained by
the entire comb can be uniform. Note that the example in which the
four or more inner comb teeth having the different tip end heights
are used as illustrated in FIG. 13(a) described above is also
applicable to the case illustrated in FIG. 13(c), and further, the
modifications illustrated in FIGS. 11, 12, etc. described above are
also applicable thereto. Note that if the structure (specification)
of the inner comb teeth is to be simplified, the tip end heights of
the inner comb teeth may be the same. In such a case, in order to
facilitate the use of the outer comb teeth as coarse teeth, it is
preferred that the inner comb teeth are aligned in the tip end
height with the tip end 20A located the lowest or the tip end 20B
located the second highest.
[0133] FIGS. 14(a) to (c) illustrate various modifications of the
tooth bottom depths of a plurality of inner comb teeth, based on
the ideas equivalent to the various modifications of the tip end
heights of the inner comb teeth illustrated in FIGS. 13(a) to (c)
described above. FIG. 14(a) corresponds to FIG. 13(a), and
illustrates one example in which the number of inner comb tooth
bottoms having different tooth bottom depths is four. In other
words, in the example of FIG. 14(a), a tooth bottom 29A located the
deepest, a tooth bottom 29B located the second deepest, a tooth
bottom 29C located the third deepest, and a tooth bottom 29D
located the shallowest are formed, and this arrayed order of the
tooth bottoms continues repeatedly in the direction illustrated by
an arrow in the X-axis direction. Thus, since the tooth bottoms are
constructed so that the four different tooth bottom depths are
repeated successively, tension produced by the tooth bottoms 29A to
29D can further be dispersed, and it becomes easy to form the
uniform backcombed hair. Further, in FIG. 14(a), a total of five or
more tooth bottoms having different tooth bottom depths is, of
course, also formed similar to the case of FIG. 13(a), and further,
the modifications illustrated in FIGS. 11, 12, etc. are also
applicable to the comb teeth which form the tooth bottoms described
above.
[0134] FIG. 14(b) illustrates one example in which the arrayed
order of the tooth bottoms having different tooth bottom depths is
reversed to the case illustrated in FIG. 6, based on the concept
equivalent to FIG. 13(b). Thus, also in FIG. 14(b), the friction on
the comb tip end side (the tip end side of the comb main body) can
be increased, and it becomes suitable because the user can suitably
sense the resistance through the entire comb, including the comb
tip end side, in an actual use scenario. Note that the example in
which the tooth bottom depth is different at the four or more
places as illustrated in FIG. 14(a) described above is also
applicable to the case illustrated in FIG. 14(b), and further, the
modifications illustrated in FIGS. 11 12, etc. described above are
also applicable thereto.
[0135] FIG. 14(c) illustrates one example in which the arrayed
order of the tooth bottoms having different tooth bottom depths is
random, based on the idea equivalent to FIG. 13(c). Thus, also in
FIG. 14(c), the tension produced at the tooth bottoms 29A to 29C is
dispersed, and it becomes easy to form the uniform backcombed hair.
Note that the example in which the tooth bottom depth is different
at four or more places as illustrated in FIG. 14(a) described above
is also applicable to the case illustrated in FIG. 14(c), and,
further, the modifications illustrated in FIGS. 11, 12, etc.
described above is also applicable thereto.
[0136] Note that in the modifications etc. illustrated in FIGS.
14(a) to (c) described above, the shape of the tooth bottoms
29A-29C is preferably a shape in which a center part thereof in the
Y-axis direction is convexed as illustrated in FIG. 7. However, in
order to disperse the tension obtained at the tooth bottoms, any of
the tooth bottoms may be formed in a flat shape, instead of the
shape illustrated in FIG. 7. Thus, the possibility of any of the
tooth bottoms being formed in the flat shape is entirely applicable
to the comb in accordance with the present invention. In such a
case, it is suitable that, in order to disperse the tension, the
flat shape is repeatedly formed at a rate of one every two or more
tooth bottoms. Further, in order to simplify the structure
(specification) of the tooth bottoms between the inner comb teeth,
the tooth bottom depths may be the same. In such a case, in terms
of easily backcombing, it is preferable to align the tooth depths
with the tooth bottom 29B located the second deepest, or the tooth
bottom 29A located the deepest (of course, such an example of the
bottom shape is also applicable to the comb 1 illustrated in FIG.
1, etc.).
[0137] FIGS. 15 and 16 illustrate examples in which the number of
rows of comb teeth is differentiated from the case illustrated in
FIG. 3. FIG. 15(a) illustrates a modification of the comb in which
the number of rows of the comb teeth is a total of four rows. The
comb is characterized by the fact that inner comb tooth members 10'
having inner comb teeth 20' are newly inserted into a comb main
body 2' on one side surface 2c' of the comb main body 2' and the
opposite side surface 2d'. Thus, from the one side surface 2c'
toward the other side surface 2d', a total of four rows of comb
teeth are formed: the outer comb teeth 7, the inner comb teeth 20,
the outer comb teeth 8, and the inner comb teeth 20'. In the
example illustrated in FIG. 15(a), compared with the case
illustrated in FIG. 3, it is advantageous in that the comb has a
structure to which the row of the inner comb teeth 20' is added,
and the tension obtained by the inner comb teeth described above
can be doubled.
[0138] FIG. 15(b) illustrates a modification of the comb in which
the number of rows of the comb teeth is a total of five rows, and
the modified comb is characterized, compared with the example
illustrated in FIG. 15(a), by the fact that a row of outer comb
teeth 9 is further provided at a side surface 2d'' which is
opposite from one side surface 2c'' of a comb main body 2''. Thus,
in the example illustrated in FIG. 15(b), since a total of three
rows of outer comb teeth 7, 8, and 9 exist, it is advantageous in
that the resistance of the hair can be increased by the hair being
caught by the outer comb teeth 7 to 9 and the inner comb teeth 20
and 20' as illustrated in FIG. 8. Note that if four or more rows of
comb teeth are provided, it is suitable, in terms of producing the
caught state of the hair as illustrated in FIG. 8, to alternately
array the row of the outer comb teeth 7 (the outer comb teeth 8)
and the row of the inner comb teeth 20 in the Y-axis direction.
[0139] FIG. 16(a) illustrates a modification of the comb in which
the number of rows of the comb teeth is a total of two, and the
modified comb is characterized, compared with the case illustrated
in FIG. 3, by the fact that the outer comb teeth are not provided
at a side surface 102d which is opposite from one side surface 102c
of a comb main body 102, but the inner comb teeth 20 of the inner
comb teeth member 10 are arrayed. Since the example illustrated in
FIG. 16(a) can be simplified in the structure, compared with the
case illustrated in FIG. 3, and the outer comb teeth 7 exists at
the one side surface 102c side, the situation in which the hair is
caught by the respective outer comb teeth and the inner comb teeth
so that the resistance as illustrated in FIG. 8 can still be
produced, and the comb can also be applied to the usage in which
the outer comb teeth 7, which exist in one row, are used as the
coarse teeth.
[0140] FIG. 16(b) illustrates a modification of the comb in which
the number of rows of the comb teeth is one, and the modified comb
is characterized, compared with the case illustrated in FIG. 3, by
having a structure in which the outer comb teeth located at one
side surface 202c side of the comb main body 202 and the outer comb
teeth located at the opposite side surface 202d side are omitted,
but only the inner comb teeth 20 of the inner comb teeth member 10
still remain in existence. In this example illustrated in FIG.
16(b), since the structure can be dramatically simplified compared
with the case illustrated in FIG. 3, it is advantageous in that the
inner comb teeth 20 having a complicated shape can be easily molded
integrally with the comb main body 52 (an integral molding with a
synthetic resin etc. becomes easier. Of course, the integral
molding of the entire comb with a synthetic resin etc. is also
technically possible for the examples other than FIG. 16(b)). Note
that the structure of each modification described above is also
applicable to any of the inner comb teeth 20 illustrated in FIGS.
15 and 16 described above (including the inner comb teeth 20'
illustrated in FIG. 15(a)).
[0141] FIG. 17 illustrates a modification of the outer comb teeth
and illustrates one example in which outer comb teeth 107 and 108
are protruding so as be tilted toward inner comb teeth 330,
respectively. Thus, since the outer comb teeth 107 and 108 are
tilted, intervals between the inner comb teeth 330 and the outer
comb teeth 107 and 108 are narrower than the case illustrated in
FIG. 7, and it is easy to increase the resistance of the hair at
the intervals between the inner comb teeth 330 and the outer comb
teeth 107 and 108. Note that in FIG. 17, the example in which a
first section 331 of the inner comb tooth 330 is formed in the
tapered shape and a second section 333 located below the stepped
part 332 is formed in the straight shape is illustrated. However,
it is also possible to use inner comb teeth having a shape other
than the shape described above. Further, in FIG. 17, although tooth
bottom 25 in FIG. 7 are illustrated (the tooth bottom shape in
which the center part 25a is convexed), upper surfaces of the tooth
bottoms 25 may be formed in a somewhat flat shape if the tension at
the tooth bottoms is too strong as described above.
[0142] FIG. 18 illustrates one example in which the structure in
accordance with the present invention is applied to a comb 350
having the structure without the bar-shaped grip part 4 illustrated
in FIG. 1. Thus, also for the comb 350 which does not have the grip
part, one row of the inner comb teeth 20 can be protruding from a
comb main body 352 as illustrated in FIG. 16(a) between comb
protecting parts 355a and 355b on both ends which protrude from
both sides of the comb main body 352 in the Z-axis direction.
Therefore, the advantages described above can be obtained by the
one row of inner comb teeth 20. Note that the inner comb teeth 20
can possibly be provided to the inner comb teeth member 10 as
described above and the inner comb teeth member 10 is then attached
to the comb main body 352, or the inner comb teeth 20 can possibly
be integrally molded with the comb main body 352. Further, also for
the comb 350 which does not have the grip part illustrated in FIG.
18, the plurality of rows of comb teeth described above may be
provided, or the various modifications described above may be
applied thereto.
[0143] FIG. 19 illustrates a comb 400 of a modification in which a
relation between the length of inner comb teeth and the length of
outer comb teeth is reversed from the case illustrated in FIG. 5. A
plurality of outer comb teeth 407 (408) of a pin shape which
protrude from an upper surface 402f of a comb main body 402 are
shorter than a comb protecting part 405a which projects from a tip
end of the comb main body 402 in the Z-axis direction. In the
meantime, although a plurality of inner comb teeth 420 (which are
comprised of inner comb teeth 430, 440, and 450) provided to the
inner comb teeth member 410 forms stepped parts 432, 442, and 452
similar to the inner comb teeth 20 (the inner comb teeth 30, 40,
and 50) illustrated in FIGS. 5, 6, etc., each tip end is formed to
be located at a same level with the comb protecting part 405a so
that the overall length is longer than the outer comb teeth 407
(408). Therefore, the tip ends of the inner comb teeth 20 (for
example, tip ends 440a of the inner comb teeth 440 illustrated in
FIG. 19) are located higher than tip ends 407a of the outer comb
teeth 407 by a height dimension H'. Note that tooth bottoms 425,
426, and 427 between the inner comb teeth are similar to the tooth
bottoms 25, 26, and 27 illustrated in FIGS. 5, 6, etc.,
respectively. Further, although FIG. 19 illustrates a part of the
modified comb 400, a relation of the inner comb teeth 420 and the
outer comb teeth 407 (408) is equivalent to the structure
illustrated in FIG. 19 also in other parts which are not
illustrated in FIG. 19.
[0144] In such a modified comb 400 illustrated in FIG. 19, since
the inner comb teeth 420 form the stepped parts 432, 442, and 452,
and the tooth bottoms 425, 426, and 427 having different bottom
depths, similar to the comb 1 illustrated in FIGS. 5, 6, etc., it
is advantageous in that the uniform backcombed hair can easily be
formed, and when the surface of the backcombed hair is smoothed
down and hairdressed, the tip ends of the inner comb teeth 420
which are longer than the outer comb teeth 407 can be used as fine
teeth. In addition, it is also advantageous in that both the
backcombed hair formation and the smoothing down (hairdressing) of
the surface of the backcombed hair can be performed by the single
comb 400. Note that since the smoothing down (hairdressing) of the
surface of the backcombed hair is only to hairdress the surface,
the tip end part of the comb teeth used for the hairdressing only
extends within a very short dimensional range. Therefore, a
numerical value example of the height dimension H' illustrated in
FIG. 19 can be considered as the value within a range from about 1
mm to about 10 mm. Generally, if the height dimension H' is about 1
mm to about 3 mm, it is enough to smooth down (hairdress) the
surface of the backcombed hair.
[0145] Further, in terms of smoothing down (hairdressing) the
surface of the backcombed hair, it is preferred that the tip ends
of the inner comb teeth 420 are formed to be located at the same
height. Therefore, among the modifications described above, the
modifications which have the tip end heights other than those
illustrated in FIGS. 13(a) to (c) can also be applied to the comb
400 illustrated in FIG. 19, and the structure of the modification
illustrated in FIG. 19 is, of course, applicable to the type which
does not have the grip part illustrated in FIG. 18.
[0146] FIG. 20 illustrates a comb 500 of a modification having a
structure in which the case illustrated in FIG. 5 is combined with
the case illustrated in FIG. 19, in terms of the relation in the
length between the inner comb teeth and the outer comb teeth. In
other words, within a section surrounded by comb protecting parts
505a and 505b which are provided on both sides of a comb main body
502 in the longitudinal direction thereof (the X-axis direction),
the comb 500 has a structure equivalent to the structure
illustrated in FIG. 19 within a first section 500a closer to the
comb protecting part 505a which is a tip end side, and has a
structure equivalent to the structure illustrated in FIG. 5 within
a second section 500b closer to the comb protecting part 505b which
is a grip part 504 side.
[0147] Specifically, inner comb teeth 520 located in the first
section 500a among the plurality of inner comb teeth of the comb
500 have a structure equivalent to the comb teeth 420 illustrated
in FIG. 19, and are formed longer than the outer comb teeth 507
(508), while inner comb teeth 620 located in the second section
500b have a structure equivalent to the comb teeth 20 illustrated
in FIG. 5, and are formed shorter than the outer comb teeth 517
(518). Note that the outer comb teeth 507 (508) located in the
first section 500a are formed shorter than the comb protecting part
505a similar to the outer comb teeth 407 (408) illustrated in FIG.
19, and, on the other hand, the outer comb teeth 517 (518) located
in the second section 500b are formed to have a length equivalent
to the length of the comb protecting part 505a (505b) similar to
the outer comb teeth 7 (8) illustrated in FIG. 5, etc. Further,
both the inner comb teeth 520 of the first section 500a and the
inner comb teeth 620 of the second section 500b are provided to the
same inner comb teeth member 510. Other than the parts described
above, the modified comb 500 has a structure equivalent to the comb
1 illustrated in FIG. 1, etc.
[0148] Since such a modified comb 500 illustrated in FIG. 20 has
the first section 500a having the structure equivalent to FIG. 19,
tip end parts of the inner comb teeth 520 in the first section 500a
can be used as fine teeth to smooth down (hairdress) the surface of
the backcombed hair. Further, the efficient uniform backcombed hair
can be formed mainly on the inner comb teeth 620 and the outer comb
teeth 517 (518) of the second section 500b. In addition, tip end
parts of the outer comb teeth 517 (518) in the second section 500b
can be used as coarse teeth. Therefore, the modified comb 500 is
advantageous in that the single comb 500 can be used for a variety
of purposes. Note that, as for the comb 500, the modification
equivalent to the illustrated case in FIG. 19 is applicable to the
first section 500a, while the various modifications described above
are applicable to the second section 500b. Further, the structure
of the modification illustrated in FIG. 20 is also applicable to
the type of the comb illustrated in FIG. 18 which does not have the
grip part.
INDUSTRIAL APPLICABILITY
[0149] In accordance with the present invention, since the scheme
where friction is easily produced at the comb teeth, intervals
between the comb teeth, and the tooth bottoms, etc. is adopted when
combing the hair, it is advantageous in that suitable tension can
be obtained in the hair when backcombing the hair, the backcombed
hair can easily be formed efficiently, and the uniformity of the
backcombed hair becomes suitable.
