Description
TECHNICAL FIELD
[0001] The present invention relates to a hair measurement tool
enabling measurement of hair length or hair angle based on an
objective index, and also enabling accurate haircuts at a desired
length.
BACKGROUND ART
[0002] Conventionally, when cutting hair at a barber shop or a
beauty shop, tools or devices for measuring hair length are not
used, and haircuts are normally performed by empirical values or
eyeball-measurements. Therefore, a desired hair length before the
haircut and the actual hair length after the haircut are often
different.
[0003] Meanwhile, during practical instruction at a barber school
or beauty school, or at a barber/beauty practical examination,
haircuts at a designated length are sometimes ordered. Since the
length of the haircut varies according to the angle at which the
hair is drawn from the scalp, it is very important at which angle,
relative to the scalp, the hair should be taken and cut. However,
since appropriate tools or devices for measuring the length or
direction (angle) of hair do not exist yet at present, when a
haircut in the same style is ordered during practical instruction
or at an examination, the hair length of the haircut that is
performed by each participant during instruction or at an
examination is likely to be variable, and moreover, from the
viewpoint of evaluating results during practical instruction or at
an examination, it is difficult to objectively measure the length
and angle of a haircut.
[0004] For reference, Patent Document 1, as described below,
discloses a front haircut aid for indicating a rough measurement
guide when cutting front hair. Moreover, FIG. 3 of Patent Document
2, as described below, discloses a haircut aid for enabling a
haircut at a designated length according to each part of the head.
Moreover, FIGS. 5 through 15 of Patent Document 3, as described
below, disclose a haircut aid to be mounted on the head with a
combination of wire-shaped members. Furthermore, Patent Documents 4
and 5 disclose stationery ruler-type haircut aids.

DISCLOSURE OF THE INVENTION
Problems to be Solved by the Invention
[0010] The front haircut aid according to Patent Document 1, as
described above, is limited to cutting front hair, and it is
impossible to apply it to any part other than the front hair. In
addition, according to the front haircut aid, the front hair is cut
by scissors along a front haircut line, and since the positioning
relative to the scissors depends on the ability of the user who
performs the haircut, it is problematic that the accuracy of the
haircut length depends on the skill of the user. Furthermore, the
haircut aid according to Patent Document 2 or 3 is large and wholly
covers the head, and the measurements require a long time.
Therefore, it is not suitable to perform haircuts at various
lengths accurately and easily. In addition, the haircut aids
according to Patent Documents 1 through 3 have the problem of being
incapable of hair angle (direction) measurements.
[0011] Meanwhile, the haircut aid according to Patent Document 4 or
5 is essentially used as a stationery tool, and since a
concave-convex structure formed in an edge part was not designed
with an accurately measured distance from an end part of the
structural member, it is problematic that the concave-convex
structure cannot be repurposed to perform accurate haircuts by
utilizing this haircut aid for positioning the scissors. In
particular, the edge part of the stationery ruler is a linear side
part, while the scalp having the hair is a curved surface. When
measuring hair length with a ruler, if the linear side part thereof
is placed on the scalp, both are in contact with each other at one
point, and the attitude (direction) of the ruler becomes unstable
(shaky) and difficult to fix. Therefore, it is problematic that the
length cannot be easily measured.
[0012] In light of the problems as described above, the purpose of
the present invention is to provide a hair measurement tool,
forming a concave part at a peripheral part of an elongated member
to be placed on the scalp for performing measurements, and at least
either one of multiple scale lines for length measurement or angled
lines for cutting direction is provided on a peripheral part of the
concave part, so as to secure a two-point contact state when placed
on the scalp, whereby hair length measurements at various parts can
be performed easily and accurately.
[0013] In addition, another purpose of the present invention is to
provide a hair measurement tool, forming notches for positioning
hairdressing scissors at positions corresponding to the scale
lines, so that the haircut can be accurately performed at measured
lengths.
Means for Solving the Problems
[0014] To achieve the object as described above, for a hair
measurement tool of the present invention, a concave part is formed
in at least one part of a peripheral part of an elongated member,
the elongated member indicating at least one of the following: the
scale lines indicating distances from the peripheral part of the
concave part, or angled lines indicating angles at the peripheral
part of the concave part. By placing the peripheral part of the
concave part on a scalp, either hair length measurement based on
the scale lines, or hair direction measurement based on the angled
lines, can be at least performed.
[0015] According to the present invention, since the concave part
is formed at the peripheral part to be placed on the scalp, the
hair measurement tool can maintain a stable state while being
pressed against the scalp. Namely, when the peripheral part of the
concave part is placed on the curved surface of the scalp, since
the concave part is in a recessed shape and does not contact the
scalp, the peripheral part comes into contact with the scalp at two
points, each of which is on each side of the concave part.
Accordingly, the attitude of the hair measurement tool placed on
the scalp becomes stable, and hair length measurement and hair
direction (angle) measurement at various parts can be performed
easily and accurately.
[0016] Moreover, according to the present invention, since the
concave part is formed at one end part to be placed on the scalp,
the stable state of the hair measurement tool, being pressed
against the scalp, can be maintained by securing the two-point
contact state. Accordingly, the attitude of the hair measurement
tool placed on the scalp becomes stable, and hair length
measurements at various parts can be performed easily and
accurately.
[0017] In addition, according to the present invention, since an
end part is formed to be inclined in the length direction, when the
hair measurement tool is placed on (pressed against) the scalp, the
attitude of the hair measurement tool is directed in the normal
line direction corresponding to the angle of the inclined one end
part relative to each part of the curved surface of the scalp, so
that the manner of use is consistent with the sense of direction of
the user.
[0018] In addition, according to the present invention, since the
angled lines are indicated at the one end part of the concave part,
with the hair measurement tool capable of maintaining a stable
attitude while pressed against the scalp, the hair direction
measurement can also be performed accurately and easily.
[0019] Furthermore, according to the present invention, since a
comb part is provided at the one end part, it becomes easier to
place the one end part on the scalp by plowing through the hair
with the comb part. Accordingly, in the case when the one end part
has difficulties in reaching the scalp due to certain types of
hair, such as thick hair or long hair, the one end part can be
securely placed on (pressed against) the scalp by plowing through
the hair with the comb part.
[0020] In addition, according to the present invention, since an
auxiliary concave part is formed at the peripheral part along the
length direction and auxiliary angled lines are also provided at
the peripheral part, the haircut direction can be measured by
placing the peripheral part of the auxiliary concave part on the
scalp. Namely, where the peripheral part of the concave part is
placed on the scalp, the state of the hair measurement tool becomes
lateral, not in a standing state against the scalp, and since a
wide range of length directions can be used for direction
measurements, a wide range of angle measurements can be performed
easily.
[0021] Furthermore, according to the present invention, since the
concave part is in a curve and the scale lines are curved lines
corresponding to the curve, the hair length measurement matching up
with the curved surface of the scalp can be performed. Namely, when
seeing a hair bundle (hair panel) of a predetermined volume, the
hair tip thereof is generally cut in a curved line corresponding to
the curved surface of the scalp, and therefore, with the curved
lines of the scale lines, natural hairdressing at a desired
accurate length can be performed.
[0022] In addition, according to the present invention, notches are
formed corresponding to the scale lines so as to catch the crest of
the hairdressing scissors, and therefore, in a state where the one
end part is pressed against the scalp as described above, with the
positioning of the crest of the hairdressing scissors at the notch
corresponding to a desired length, a haircut at the desired length
can be performed.
[0023] In addition, according to the present invention, since the
notches are formed on whole circumferential surfaces of the
elongated member, the positioning of the crest of the hairdressing
scissors can be performed along any of the whole circumferential
directions of the hair measurement tool, and a haircut at an
accurate length can be performed along a preferred direction of
user.
[0024] And furthermore, according to the present invention, when
the length of the hair (hair bundle) is measured with scale lines,
it is expected that the hair bundle as the measurement object is
often set (placed) on the hair measurement tool, and to prevent the
hair bundle, for example, from dropping out of the hair measurement
tool as the measurement object, the member constituting the hair
measurement tool is formed by a material capable of elastic
deformation to be warped in the width direction, so that the hair
measurement tool is deformed by the grip strength of the user in a
warped state surrounding the hair bundle as the measurement object
in the width direction, so that the hair bundle will not drop out
easily, and the length measurement can be performed smoothly.
[0025] Furthermore, according to the present invention, the member
constituting the hair measurement tool is a long-plate-shaped
member folded over to be capable of opening and closing, and
therefore, in the open state, an end side of the one end part
becomes a V-shape, and when the one end part is placed on the
scalp, three points contact the scalp, and this three-point contact
can provide more stable measurements. In addition, by arranging the
hair measurement tool so as to accommodate the hair bundle as the
measurement object in the hair measurement tool in the open state,
the hair bundle will not drop out easily, and length measurements
can be performed smoothly.
Effects of the Invention
[0026] According to the present invention, since the concave part
is formed at the peripheral part to be placed on the scalp, the
stable pressed state of the hair measurement tool against the scalp
can be maintained, and hair length measurement or hair direction
measurement at various parts can be performed easily and
accurately.
[0027] Furthermore, according to the present invention, since the
concave part is formed at the one end part to be placed on the
scalp, the stable pressed state against the scalp can be maintained
by securing the two-point contact state, whereby the stable state
of the hair measurement tool pressed against the scalp can be
maintained, and hair length measurements at various parts can be
performed easily and accurately.
[0028] According to the present invention, since the one end part
is formed to be inclined in the length direction when the hair
measurement tool is placed on the scalp, the hair measurement tool
can be directed in a prescribed direction corresponding to the
inclined angle of the one end part relative to each part of the
curved surface of the scalp, so that the manner of use is
consistent with the sense of direction of the user.
[0029] According to the present invention, since the angled lines
are indicated at the one end part of the concave part, hair
direction measurements can also be performed accurately and
easily.
[0030] According to the present invention, since the comb part is
provided at the one end part, even in the case when the one end
part has difficulties in reaching the scalp due to certain types of
hair, the one end part can be securely placed on (pressed against)
the scalp by plowing through the hair with the comb part.
[0031] According to the present invention, since the auxiliary
concave part is formed at the peripheral part along the length
direction and the auxiliary angled lines are also provided at that
peripheral part, a wide range of angle measurements can be
performed easily.
[0032] According to the present invention, since the concave part
is in a curve and the scale lines are curved lines corresponding to
the curve, the hair length measurements can be performed
corresponding to the curved-surface-shape of the scalp.
[0033] According to the present invention, since the notches are
formed corresponding to the scale lines so as to catch the crest of
the hairdressing scissors, a haircut at the desired length can be
performed.
[0034] According to the present invention, since the notches are
formed on the whole circumferential surface of the elongated
member, a haircut at an accurate length can be performed along the
preferred direction of the user.
[0035] According to the present invention, since the member
constituting the hair measurement tool is formed by material
capable of elastic deformation to be warped in the width direction,
when the hair measurement tool is deformed by the grip strength of
the user in the warped state surrounding the hair bundle as the
measurement object in the width direction, the hair bundle will not
drop out easily, and length measurements can be performed
smoothly.
[0036] According to the present invention, since the member
constituting the hair measurement tool is a long-plate-shaped
member folded over to be capable of opening and closing, in the
open state, more stable measurements can be performed with the
three-point contact with the scalp, and the hair bundle during
measurement can be securely prevented from dropping out, whereby
the length measurement can be performed smoothly.

MODES FOR CARRYING OUT THE INVENTION
[0061] FIG. 1 is a perspective view schematically showing an
overview of the structure of a hair measurement tool 1 according to
an embodiment of the present invention. As illustrated in FIGS. 4
and 5, the hair measurement tool 1 is used by placing it on the
scalp of head having hair (head of hair), which enables accurate
measurement of hair or hair bundles of the head (hair panel),
measurement of the direction in which the hair is to be stretched
during the measurement of length (direction in which the hair is
taken), and accurate haircuts at a desired length.
[0062] As illustrated in FIG. 1, the hair measurement tool 1
according to the present embodiment comprises an elongated member 2
formed by a flat, long-plate shape made of synthetic resin, and the
overall appearance is similar to a common stationery ruler. In
contrast to the common stationery ruler, at one end part 2a
(corresponding to one section of a peripheral part) of the
elongated member 2 constituting the hair measurement tool 1, a
curved concave (concave part 3) is formed so that the center in the
width directions thereof is the deepest, scale lines 6 are
indicated on one surface 2e with intervals at a predetermined
length unit from the one end part 2a in conformity with the curve
of the concave part 3, and notches 4 are formed in both side
surfaces 2c and 2d corresponding to each of the scale lines 6. Note
that the X-axis direction as illustrated in FIG. 1 is a length
direction of the hair measurement tool 1, the Y-axis direction is a
width direction perpendicular to the length direction of the hair
measurement tool 1, and the Z-axis direction is a height direction
of the hair measurement tool 1 (the direction perpendicular to both
the length direction and the width direction, i.e., the thickness
direction of the hair measurement tool 1). The same applies to
other drawings. Below, the hair measurement tool 1 will be
explained in detail.
[0063] The hair measurement tool 1 of the present embodiment has a
longitudinal length (in the X-axis direction) of about 360 mm, and
a lateral width (in the Y-axis direction) of 50 mm (in FIG. 1, the
hair measurement tool 1 is illustrated by cutting at the
intermediate part in the length direction). Although the size of
the hair measurement tool 1 is not limited to the above values
(length 360 mm, width 50 mm), when taking into account the
measurement of the hair bundle that is set on the hair measurement
tool 1, it is desirable to secure a width larger than approximately
20 mm. When taking into account the user-friendliness (easiness of
handling) of the hair measurement tool 1 while also guaranteeing
the ease of setting the hair bundles, it is desirable to set the
ratio of the length and the width, when the ratio of the width is
1, to be within a range of approximately 5:1 to 10:1
(length:width).
[0064] Moreover, the material of the hair measurement tool 1 is not
limited to synthetic resin, and for example, any natural material
such as wood or bamboo can also be applied. Furthermore, although
the elongated member 2 with a thickness in the range of about 0.5-5
mm can be adopted as the hair measurement tool 1, when taking into
account the ease of holding and required stiffness, for example,
the desirable thickness is about 1-2 mm.
[0065] As described above with the drawing of FIG. 2(a), the
concave part 3 is formed on an end surface of the one end part 2a.
The concave part 3 has a slightly smaller curvature than the
smallest curvature part of common human head (for example, the
approximate radius=100 to 120 mm).
[0066] Furthermore, the hair measurement tool 1 indicates scale
lines 6 on the one surface 2e (applied to the one surface 2e), in
solid lines (thickness about 0.6 mm) from the one end part 2a, with
intervals every 10 mm. These scale lines 6 are curved lines having
the same curvature as that of the concave part 3. Furthermore, the
hair measurement tool 1 indicates intermediate scale lines 7 in
dashed lines, at the intermediate position between the one end part
2a and the first scale line 6, and another intermediate position
between the second scale line 6 and the subsequent scale line 6,
and so on, so that the intermediate scale lines are indicated
between all the adjacent scale lines 6. These intermediate scale
lines 7 are also curved lines like the scale lines 6. In addition,
at every position in increments of 1 mm from the one end part 2a
(excluding the positions of the scale lines 6 and the intermediate
scale lines 7), 1-mm scale lines, which are thinner lines than each
of the scale lines 6, are indicated (the 1-mm scale lines are also
curved lines like the scale lines 6 and the intermediate scale
lines 7). With each of the scale lines 6, 7 having such curves, for
example, having the same curvature as that of the concave part 3,
the measurement can be performed in a state in which the hair
bundle has naturally curved hair tips. Note that, with reference to
the drawings other than FIGS. 2(a) and 2(c), for the purpose of
avoiding complicated illustrations, the indication of 1-mm scale
lines is omitted (in FIGS. 4, 5, for example, the intermediate
scale lines 7 are also omitted). Furthermore, the thickness of the
1-mm scale lines varies within a range of 10 mm. The 1-mm scale
line closer to the one end part 2a is the thinnest, and with
increasing distance from the one end part 2a, each of the 1-mm
scale lines becomes thicker. For example, the thickness of the 1-mm
scale line closest to the one end part 2a is 0.20 mm, and the
second 1-mm scale line is 0.22 mm, the third second 1-mm scale line
is 0.24 mm, the fourth 1-mm scale line is 0.26 mm, the sixth 1-mm
scale line is 0.28 mm, the seventh 1-mm scale line is 0.30 mm, the
eighth 1-mm scale line is 0.32 mm, and the ninth 1-mm scale line is
0.34 mm (the fifth scale line is a dashed line, as described
above). With this variation of line thicknesses of each of the 1-mm
scale lines, each 1-mm scale line can be read easily. Note that, to
the contrary, it is also possible that the 1-mm scale line closest
to the one end part 2a is the thickest, and that the thickness
becomes thinner with increasing distance from the one end part
2a.
[0067] The hair measurement tool 1 indicates values on the one
surface 2e, per scale line 6 as described above, showing the length
from the one end part 2a (for example, the first scale line 6 from
the one end part 2a indicates "10" as the value showing the length
of 10 mm, and the second scale line 6 from the one end part 2a
indicates "20" as the value showing the length of 20 mm). In
addition, the hair measurement tool 1 also indicates values on the
one surface 2e, per intermediate scale line 7 as described above,
showing the length from the one end part 2a (for example, the first
intermediate scale line 7 from the one end part 2a indicates "5" as
the value showing the length of 5 mm, and the second intermediate
scale line 7 from the one end part 2a indicates "15" as the value
showing the length of 15 mm). Moreover, the hair measurement tool 1
indicates three white arrows 9 in total, respectively pointing the
side of the one end part 2a, on the side of the one end part 2a of
the one surface 2e.
[0068] Furthermore, the hair measurement tool 1 has V-shaped
notches 4 formed on both of the side surfaces 2c, 2d. Each of the
notches 4 is formed exactly at the position corresponding to the
scale line 6. FIG. 3(a) is an enlarged view of the notch 4 formed
on the one side surface 2d, and the notch 4 according to the
present embodiment has about 2 mm of notch width W (opening width)
between both end parts 4b, 4c of a notch entrance, and also has
about 1.5 mm of notch depth D from the side surface 2d to a bottom
peak 4a. With this structure, the crest, which is the back of a
cutting blade of the hairdressing scissors, can be caught (hooked)
by the notch 4.
[0069] FIG. 3(b) illustrates common hairdressing scissors S. The
hairdressing scissors S are composed of a member serving as a
moving blade, and a member serving as a stationary blade (that is
the member in which a finger hook is projecting from a finger
ring), overlaid and rotatably connected by a screw, and each of the
members serving as the moving blade and the stationary blade,
respectively, has the cutting blade on the tip side from a
connected position.
[0070] Namely, the member serving as the stationary blade has a
cutting blade Sa on a distal side from the connected position, and
the cutting blade Sa has a blade tip Sb on the side facing the
moving blade, and also has a crest Sc on the opposite side, which
is the back side of the cutting blade Sa. As illustrated in FIG.
3(c), the cross section of the blade tip Sb is in a tapered wedge
shape, and the thickness of the crest Sc is equivalent to that of
the member serving as the stationary blade. Moreover, the cutting
blade Sa of FIG. 3(c) is the cross section of FIG. 3(b) as seen by
the line A-A, and the cross section is a blade reverse surface
having a slight clearance on the side slidably moving and facing
against the moving blade. The crest Sc of this cutting blade Sa has
a corner (edge), and when the crest Sc is placed on the notch 4 of
the hair measurement tool 1 as described above, the corner (edge)
of the crest Sc is exactly accommodated and caught in the inside of
the notch 4, whereby the positioning of the cutting blade Sa of the
hairdressing scissors S can be performed (see FIG. 3(c), FIG.
7(b)).
[0071] Furthermore, FIG. 2(b) is a view of the hair measurement
tool 1 as seen from the one side surface 2c. The plurality of
cutout-shaped notches 4 exists on the side surface 2c, and at the
same time, the scale lines 6 meet with the bottom peaks 4a of the
notches 4, so that the position per 10 mm can be confirmed also
from the side surface 2c. Furthermore, the intermediate scale lines
7 in dashed lines are also indicated by extending around the side
surface 2c. Moreover, the other side surface 2d of the hair
measurement tool 1 has substantially the same structure as that of
the one side surface 2c as illustrated in FIG. 2(b).
[0072] FIG. 2(c) is an enlarged plan view showing the vicinity of
another end part 2b of the hair measurement tool 1. The end surface
of the other end part 2b is a projecting concave part 8, in a shape
where the concave part 3 of the one end part 2a directly shifts in
the X-axis direction, in which a center part 8a in the width
direction is the outermost extruding part, while the positions in
the width direction of the end parts 8b, 8c are set back from the
center part 8a. Moreover, the one surface 2e of the other end part
2b has substantially the same structure as that described in FIG.
2(a); namely, the scale lines 6, the intermediate scale lines 7 and
the 1-mm scale lines are indicated on the one surface 2e, and the
notches 4 are formed on both side surfaces 2c, 2d corresponding to
the respective positions of the scale lines 6.
[0073] Furthermore, for another surface 2f of the hair measurement
tool 1, that is the opposite side (reverse side) of the one surface
2e, the structure thereof is substantially the same as that
illustrated in FIGS. 2(a) and 2(c). Accordingly, the hair
measurement tool 1 indicates the scale lines 6 and the intermediate
scale lines 7 on the whole circumferential surfaces of the
elongated member 2, and consequently, a user can confirm the scale
lines 6 and the intermediate scale lines 7 from any side of the
hair measurement tool 1, so that the measurement of hair (hair
bundle) can be performed.
[0074] FIGS. 4(a) and 4(b), as well as FIG. 5 illustrate
applications of the hair measurement tool 1 as described above, and
in each of these applications, as an explanatory example, a head
model (commonly referred to as a "wig") for cutting exercises is
used as a cutting object, but the applications in the case of a
human head are substantially the same. A head model H is a whole
model of a human head, into which hair is implanted (moreover, in
FIGS. 4(a) and 4(b) and FIG. 5, for the purpose of clarifying the
applications, the hair implanted into the head is omitted, and the
hair is illustrated only in the necessary parts).
[0075] FIG. 4(a) is a perspective view as seen from the side of the
head model H, showing the case of measurement in which the one
surface 2e of the hair measurement tool 1 and the side of the head
model H are aligned with each other. In this measurement, hair
bundles (hair panels) h1, h2, and h3 as the measurement objects,
whose respective width is about 10-50 mm, are picked from the head,
and these hair bundles h1, h2 and h3 are measured by the hair
measurement tool 1. For example, as illustrated in FIG. 4(a), when
the hair bundle h3, positioned in the upper part of the back of the
head, is measured, the hair bundle h3 picked from the head is
raised from a scalp Ha, and the hair bundle h3 is applied to the
one surface 2e of the hair measurement tool 1. At that time, the
one end part 2a of the hair measurement tool 1 is placed on
(pressed against) the scalp Ha, which is a root position of the
hair bundle h3 of the head model H.
[0076] FIG. 6(a) illustrates a state in which the one end part 2a
of the hair measurement tool 1 is pressed against the scalp Ha in
the vicinity of the back of the head (FIG. 4(a) is a view
corresponding to a case in which the hair bundle h3 is measured).
Since the one end part 2a of the hair measurement tool 1 has the
concave part 3 formed in the structure as described above, when the
one end part 2a is pressed against the scalp Ha, end parts 3b, 3c
in the width direction of the concave part 3 come into contact with
the scalp Ha. Namely, the curvature of the concave part 3 is
slightly smaller than the smallest curvature position of the common
human head, and since the curvature of the implanted position of
the hair bundle h3 of the head model H is close to the flat
surface, a gap from the scalp Ha occurs in the vicinity of the
center of the concave part 3, and only the end parts 3b, 3c contact
the scalp Ha. Therefore, when the hair measurement tool 1 is
pressed against the scalp Ha, both end parts 3b, 3c come into
two-point contact with the scalp Ha, thus the hair measurement tool
1 will not be shaken in the directions of the white arrows of FIG.
6(a) (the right and left directions), and a stable attitude can be
maintained (the unstable state as shown by the white arrow
directions will not occur).
[0077] Furthermore, FIG. 7(a) illustrates a state in which the
length of the hair bundle h3 is measured by the hair measurement
tool 1. In this measurement, the length of the hair bundle h3,
aligned on the one surface 2e of the hair measurement tool 1, is
measured by the scale lines 6 and the intermediate scale lines 7
(or the 1-mm scale lines as described above) indicated on the one
surface 2e. Moreover, when a predetermined volume of hair bundle
such as the hair bundle h3 is measured, it is desirable to measure
by the total average value, not by the unit of a single hair
strand. When this measurement is performed, as explained in FIG.
6(a), as long as the one end part 2a of the hair measurement tool 1
is pressed against the scalp Ha, shaking in the right and left
directions will not occur, thus a stable measurement can be
performed, and with comparative reference between each of the scale
lines 6, 7, for example, and the hair as the measurement object,
the length can be measured accurately. In addition, since each of
the scale lines 6 and 7, for example, are curved lines, the hair
tips can be measured along with their curve, thus the trimming of
hair tips cut by a natural curved line, in accordance with the
curved surface of the scalp Ha, is facilitated.
[0078] Moreover, it is also possible to measure the other hair
bundles h1 and h2, as illustrated in FIG. 4(a), in the same manner
as that of the hair bundle h3 described above. Furthermore, the
measurement of hair can be performed, not only by the unit of one
hair bundle (hair panel) as described above, but also, of course,
by the unit of one hair strand, two hair strands, and when the
measurement by the unit of one hair strand, two hair strands is
performed by using the hair measurement tool 1 of the present
invention, it is useful for detecting natural hair loss, hair
breakage, or non-implanted hair.
[0079] FIG. 4(b) is a view as seen from the front of the head model
H, showing the case of measurement in which the one surface 2e of
the hair measurement tool 1 and the front of the head model H face
the same direction. Also in this measurement, hair bundles h10,
h11, and h12 as the measurement objects are picked from the head,
and these hair bundles h10, h11 and h12 are measured by the hair
measurement tool 1, like the case of FIG. 4(a).
[0080] FIG. 6(b) illustrates a state in which the one end part 2a
is pressed against the scalp Ha, when the hair measurement tool 1
measures the hair bundle h11 implanted in the vicinity of the top
of the head of the head model H of FIG. 4(b). Although the
curvature in the vicinity of the top of the head of the head model
H is different from the curvature in the vicinity of the back of
the head in which the hair bundle h3 is implanted as described in
FIG. 6(a), since the curvature of the concave part 3 of the hair
measurement tool 1 is slightly smaller than the smallest curvature
position of the common human head, also in this case, both end
parts 3b and 3c of the one end part 2a of the hair measurement tool
1 contact the scalp Ha. Accordingly, the hair measurement tool 1
will not be shaken in the directions of the white arrows of FIG.
6(b) (the right and left directions), and a stable length
measurement can be performed.
[0081] FIG. 5 is a view as seen from the top of the head model H,
showing the case of measurement in which the one surface 2e of the
hair measurement tool 1 and the top of the head model H face the
same direction. Also in this measurement, hair bundles h20, h21,
and h22 as the measurement objects are picked from the head, and
these hair bundles h20, h21, and h22 are measured by the hair
measurement tool 1, like the case of FIG. 4(a). Also in this case,
since the end part 2a of the hair measurement tool 1 being pressed
against the scalp Ha comes into two-point contact as illustrated in
FIGS. 6(a) and 6(b), a stable measurement can be performed.
Moreover, FIGS. 4(a) and 4(b) as well as FIG. 5 are examples of
length measurement, and substantially the same measurement can be
performed at any other position of the head.
[0082] Meanwhile, FIG. 7(b) illustrates a cut state of a hair
bundle h30 by the hairdressing scissors S, with the hair
measurement tool 1. A desired cut length of the hair bundle h30 is
measured in the states such as described above in FIG. 4 and FIG.
5, and the crest Sc, which is the opposite side to the blade tip Sb
of the cutting blade Sa, is aligned with the notch 4 at the
position of the scale line 6 corresponding to the measured cut
length. When the crest Sc of the cutting blade Sa is aligned with
the notch 4, as explained in FIG. 3(c), the crest Sc of the cutting
blade Sa is hooked and caught by the notch 4, and the position of
the cutting blade Sa is restricted. Accordingly, the cut position
naturally becomes the position indicated by the scale line 6,
corresponding to the notch 4 accommodating the crest Sc of the
cutting blade Sa, and an accurate cut can be performed at the
user's intended length based on the scale line 6.
[0083] Moreover, the present invention is not limited to the hair
measurement tool 1 of the embodiment as described above, and many
modifications exist. FIG. 8(a) is a plan view showing the essential
parts of the hair measurement tool 10 of a first modification,
characterized in that, in addition to notches 14 formed on side
surfaces 12c, 12d corresponding to the scale lines in solid lines,
intermediate notches 19 are also formed therein corresponding to
the intermediate lines in dashed lines (the other parts are
substantially the same as those of the hair measurement tool 1 of
FIG. 1, for example). The intermediate notch 19 is formed in a
smaller size than that of the notch 14, for easy distinction from
the notch 14 (for example, as compared with the notch 14 having the
notch width of about 2 mm and the notch depth of about 1.5 mm, the
intermediate notch 19 has the notch width of 1.5 mm and the notch
depth of 1 mm). Accordingly, other than with the notches 14, as
illustrated in FIG. 7(b), also with the intermediate notches 19,
the positioning (position restriction) of the cutting blade Sa of
the hairdressing scissors S can be performed, and with the hair
measurement tool 10 of the first modification, an accurate cut at
more minute unit sizes can be performed.
[0084] FIG. 8(b) is a side view showing the essential parts of a
hair measurement tool 20 of a second modification, characterized in
that each notch 24, provided corresponding to the scale lines in
solid lines, is formed on the whole circumferential surfaces of the
elongated member constituting the hair measurement tool 20 (the
other parts are substantially the same as those of the hair
measurement tool 1 of FIG. 1, for example). Namely, each of the
notches 24 on one side surface 22c, as illustrated in FIG. 8(b),
continues to one surface 22e and another surface 22f (in FIG. 8(b),
the positions shown by "V"-shaped recesses on the one surface 22e
and the other surface 22f correspond to the notches 24), and
furthermore, although not illustrated, the notches 24 also continue
to another side surface. With these notches 24 continuously formed
on the whole circumferential surfaces, the positioning (position
restriction) of the cutting blade of the hairdressing scissors used
for haircut can be performed at a desired position by the notch 24
along the whole circumferential direction of the hair measurement
tool 20, and when an individual user (beautician, barber) performs
a haircut along the direction for easily performing the haircut,
the cutting position of the hairdressing scissors can be guided
with flexibility.
[0085] FIGS. 9(a) and 9(b) are plan views showing one end part 32a
and another end part 32b of a hair measurement tool 30 of a third
modification. Unlike the hair measurement tool 1 shown in FIG. 1,
for example, the hair measurement tool 30 of the third modification
does not have a concave part in the one end part 32a, and has a
straight-line shape, with the one end part 32a and the other end
part 32b perpendicular to both side surfaces 32c, 32d. Furthermore,
each of the scale lines in solid lines and the intermediate scale
lines in dashed lines is also a straight line parallel to end
surfaces of the one end part 32a and the other end part 32b, with
notches 34 formed on the side surfaces 32c, 32d corresponding to
the respective scale lines in solid lines.
[0086] And furthermore, the hair measurement tool 30 of the third
modification indicates, on one surface 32e of the one end part 32a
and the other end part 32b, width scale lines 31 in solid lines and
width intermediate scale lines 39 in dashed lines, with intervals
at a predetermined length unit in the width direction (Y-axis
direction).
[0087] The width scale lines 31 indicate the length with intervals
every 10 mm from the one side surface 32d, and a value (10, 20, 30,
40) showing the length from the one side surface 32d is allotted to
each of the width scale lines 31. Furthermore, the intermediate
width scale lines 39 are indicated at the intermediate position
between the one side surface 32d and the first width scale line 31,
and also at the intermediate positions between each of the second
and subsequent width scale lines 31. With the width scale lines 31
and the intermediate width scale lines 39 provided on the one end
part 32a and the other end part 32b, the width of the hair bundle
(hair panel) as the measurement object or the cutting object can be
confirmed by the width scale lines 31 and the intermediate width
scale lines 39, whereby the volume of the hair bundle (hair panel)
as the measurement object or the cutting object can be roughly
estimated by the size, that is by the width.
[0088] Moreover, the width scale lines 31 and the intermediate
width scale lines 39 can be indicated, not only on the one surface
32e, but also on an end surface of the one end part 32a or the
other end part 32b, and when the indication is applied to the end
surface, it is also possible to confirm the width of the picked
hair bundle (hair panel) on the side of the end surface. It is, of
course, possible to indicate the width scale lines 31 and the
intermediate width scale lines 39 on the other surface on the
reverse side of the one surface 32e. Furthermore, it is also
possible to provide the width scale lines 31 and the intermediate
width scale lines 39 only on either side of the one end part 32a or
the other end part 32b, and when provided in the one end part 32a
only, the hair bundle width can be measured on the root side from
which the hair is growing, and when provided in the other end part
32b only, the hair bundle width can be measured on the hair tip
side.
[0089] FIG. 9(c) illustrates one end part 42a of a hair measurement
tool 40 of a fourth modification, and the hair measurement tool 40
of the fourth modification is exactly a combination of the hair
measurement tool 1 as illustrated in FIG. 1, for example, with the
hair measurement tool 30 of the third modification as illustrated
in FIGS. 9(a) and 9(b), wherein width scale lines 41 in solid lines
and intermediate width scale lines 49 in dashed lines are provided
in the one end part 42a, with intervals at a predetermined length
unit in the width direction (Y-axis direction) (the other parts are
substantially the same as those of the hair measurement tool 1 of
FIG. 1, for example). With the width scale lines 41 and the
intermediate width scale lines 49, even at the one end part 42a in
a curve, the width of the hair bundle (hair panel) as the
measurement object or the cutting object can be confirmed.
[0090] FIG. 10(a) illustrates one end part 52a of a hair
measurement tool 50 of a fifth modification, and the hair
measurement tool 50 of the fifth modification is exactly in a shape
where a comb part is provided in the one end part 2a of the hair
measurement tool 1, as illustrated in FIG. 1, for example. Namely,
the hair measurement tool 50 is provided with a comb part 51,
having a plurality of comb tines 51a, in the one end part 52a, and
the other parts are substantially the same as those of the hair
measurement tool 1 as illustrated in FIG. 1, for example, with the
scale lines in curved solid lines and the intermediate scale lines
in curved dashed lines, and also with notches 54 formed on side
surfaces 52c, 52d.
[0091] The tips of the comb tines 51a of the comb part 51 are
aligned along an imaginary curved line, whose curve corresponds to
the end surface of the one end part 2a of the concave part 3 of the
hair measurement tool 1 as illustrated in FIG. 1, for example.
Accordingly, even when the tips of the comb tines 51a are pressed
against the scalp Ha of the head as illustrated in FIGS. 4 and 5,
like the case of the hair measurement tool 1 as illustrated in FIG.
1, for example, the length of hair (hair bundle) can be measured
with the two-point contact by the comb tines on both ends. Since
each of the comb tines 51a is pressed against the scalp Ha, when
taking into account the application for the human head, it is
desirable to form the round-shaped tips to some degree, so as not
to form steeple-shaped tips. Furthermore, according to the example
as illustrated in FIG. 10(a), the tine length of each of the comb
tines 51a is about 5 mm, but the tine length is not limited to this
example, and it is possible to apply various lengths in a range
from approximately 1-10 mm, and in particular, when a reliable comb
function (the function to plow through the hair) is desired, it is
desirable to secure a tine length of more than 3 mm.
[0092] FIG. 10(b) is a schematic perspective view showing an
application of the hair measurement tool 50. Since the hair
measurement tool 50 has the comb part 51 in the one end part 52a,
in the case of hair length measurement, when the one end part 52a
is pressed against the scalp Ha, it is possible to plow through
hair bundles h40, h41 by the comb tines 51a of the comb part 51
provided in the one end part 52a. Furthermore, since each of the
individual hair strands constituting the plowed-through hair
bundles h40, h41 enters the space between each of the comb tines
51a, the tips of the comb tines 51a can contact the scalp Ha.
Accordingly, even when the thick hair (hair bundle) of the head is
measured, with the plow-through of hair by the comb part 51, the
one end part 52a (the tips of the comb tines 51a) of the hair
measurement tool 50 of the fifth modification can be securely
pressed against the scalp, whereby the hair length can be measured
accurately.
[0093] FIG. 11(a) is a plan view showing one end part 62a of a hair
measurement tool 60 of a sixth modification. The hair measurement
tool 60 of the sixth modification is chiefly a modification of the
shape of the concave part 3 of the one end part 2a of the hair
measurement tool 1 as illustrated in FIG. 1, for example. Namely,
the hair measurement tool 60 is characterized so that both end
parts 63b, 63c of a concave part 63 in the width direction (Y-axis
direction) are in round shapes (arc shapes with R), not in steeple
shapes of the end parts 3b, 3c of the concave part 3 of the hair
measurement tool 1 as illustrated in FIG. 1, for example.
Furthermore, the curvature (degree of curve) of the concave part 63
is larger than the concave part 3 of FIG. 1, so that a center part
63a of the concave part 63 recesses deeper than that of FIG. 1.
[0094] In addition, unlike the hair measurement tool 1 as
illustrated in FIG. 1, for example, scale lines 66 in solid lines
and intermediate scale lines 67 in dashed lines indicated on one
surface 62e of the hair measurement tool 60 are straight lines.
This is because, since the degree of the curvature of the concave
part 63 is larger than that of the hair measurement tool 1 as
illustrated in FIG. 1, for example, if curved lines like those of
the hair measurement tool 1 are applied, the degree of curvature of
each scale line will become too large, and the length measurement
cannot be performed easily. Therefore, for the purpose of avoiding
such a situation, the scale lines 66 and the intermediate scale
lines 67 are straight lines (the scale lines 66 and the
intermediate scale lines 67 are straight lines perpendicular to
side surfaces 62c, 62d). Moreover, the other parts of the hair
measurement tool 60 are substantially the same as those of the hair
measurement tool 1 as illustrated in FIG. 1, for example, with
notches 64 formed on the side surfaces 62c, 62d. When the one end
part 62a of the hair measurement tool 60 is pressed against the
scalp, since both end parts 63b, 63c of the concave part 63
contacting the scalp are in round shapes, a gentle feeling is given
to the scalp on contact, and at the same time, since the end parts
63b, 63c come into contact corresponding to the curvature of the
scalp, a secure two-point contact can be obtained.
[0095] FIGS. 11(b) and 11(c) are plan views showing one end part
72a and another end part 72b of a hair measurement tool 70 of a
seventh modification. The one end part 72a of the hair measurement
tool 70 of the seventh modification is in an oblique shape and
curve in the length direction (X-axis direction), forming a concave
part 73 having a recessed substantial center part 73a. The oblique
side of the concave part 73, inclining at an angle of about 45
degrees with respect to the length direction (X-axis direction),
has the curvature equivalent to that of the concave part 3 of the
hair measurement tool 1 as illustrated in FIG. 1, for example.
[0096] With the concave part 73 of the hair measurement tool 70 of
the seventh modification, in a state of being pressed against the
head, the attitude of the hair measurement tool 70 is aligned with
the absolute vertical direction or the absolute horizontal
direction, facilitating user-friendliness as an index matching the
sense of direction of the user (beautician or barber). Namely, when
the user (beautician or barber) performs a haircut or hair setting,
the user will unconsciously utilize lines indicating the vertical
direction or lines indicating the horizontal direction existing
around the working space, such as the vertical lines or the
horizontal lines of rectangular mirror frames, or the vertical
lines or the horizontal lines of cabinet, as the rough index for a
substantially vertical direction or a substantially horizontal
direction. Therefore, since the position of the hair measurement
tool 70 pressed against the scalp can indicate a substantially
vertical direction or a substantially horizontal direction, the
attitude thereof is aligned with the vertical lines in the vertical
direction or the horizontal lines in the horizontal direction
existing as a rough index in the working space of the user,
matching the sense of direction of the user, effective for
practical usage (see FIGS. 12(a) and 12(b)).
[0097] Furthermore, scale lines 76 in solid lines and intermediate
scale lines 77 in dashed lines indicated on one surface 72e of the
hair measurement tool 70 are curved lines having the same curvature
as those of the concave part 73 (the concave part). Moreover, at
the other end part 72b of the hair measurement tool 70, as
illustrated in FIG. 11(c), the scale lines 76 and the intermediate
scale lines 77 are discontinued, due to their oblique curved lines,
on the side of a side surface 72d in the upper part of the drawing.
The other parts of the hair measurement tool 70 of the seventh
modification are substantially the same as those of the hair
measurement tool 1 as illustrated in FIG. 1, for example, and
notches 74 are formed on a side surface 72c and the side surface
72d.
[0098] FIGS. 12(a) and 12(b) illustrate applications of the hair
measurement tool 70 of the seventh modification for the head model
H. Moreover, like the cases of FIGS. 4(a) and 4(b) as well as FIG.
5, also in FIGS. 12(a) and 12(b), for the purpose of clarifying the
applications, all the hair is omitted, and the hair (head of hair)
is illustrated only in the necessary parts (hereinafter, the same
applies to FIGS. 20, 21, 23 and 24).
[0099] FIG. 12(a) is a view as seen from the side of the head model
H, showing the case of measurement in which the one surface 72e or
another surface 72f of the hair measurement tool 70, and the side
of the head model H, are aligned with each other. For example, when
the length of a hair bundle h50, implanted in the vicinity of the
neck at the back of the head of the head model H, is measured, the
one end part 72a of the hair measurement tool 70 is pressed against
the scalp in a state in which the one surface 72e and the side of
the head model H face the same direction. Here, the scalp Ha of the
head model H in the vicinity of the neck at the back of the head is
an oblique downward curved surface, as illustrated by a
left-oriented downward line in FIG. 12(a), and when the one end
part 72a of the hair measurement tool 70 is pressed against this
downward curved surface of the scalp Ha, because of the shape of
the concave part 73 of the one end part 72a, the attitude of the
hair measurement tool 70 is substantially directed in the
horizontal direction.
[0100] In addition, also when the length of a hair bundle h51,
implanted in the vicinity of the rear at the top of the head of the
head model H, is measured, the one end part 72a of the hair
measurement tool 70 is pressed against the scalp Ha in a state in
which the one surface 72e and the side of the head model H are
aligned with each other. The scalp Ha of the head model H in the
vicinity of the rear at the top of the head is an oblique upward
curved surface, as illustrated by a right-oriented downward line in
FIG. 12(a), and when the one end part 72a of the hair measurement
tool 70 is pressed against this upward curved surface of the scalp
Ha, because of the shape of the concave part 73 of the one end part
72a, the attitude of the hair measurement tool 70 is substantially
directed in the vertical direction.
[0101] Furthermore, when the length of a hair bundle h52, implanted
in the vicinity of the front at the top of the head of the head
model H, is measured, the one end part 72a of the hair measurement
tool 70 is pressed against the scalp Ha in a state in which the
other surface 72f and the side of the head model H are aligned with
each other. The scalp Ha of the head model H in the vicinity of the
front at the top of the head is an oblique upward curved surface,
as illustrated by a left-oriented downward line in FIG. 12(a), and
when the one end part 72a of the hair measurement tool 70 is
pressed against this upward curved surface of the scalp Ha, because
of the shape of the concave part 73 of the one end part 72a, the
attitude of the hair measurement tool 70 is substantially directed
in the vertical direction.
[0102] On the other hand, FIG. 12(b) is a view as seen from the
front of the head model H, showing the case of measurement in which
the one surface 72e or the other surface 72f of the hair
measurement tool 70, and the front of the head model H, face the
same direction. For example, when the length of a hair bundle h53,
implanted in the vicinity of the left upper part of the head model
H, is measured, the one end part 72a of the hair measurement tool
70 is pressed against the scalp Ha in a state in which the other
surface 72f and the front of the head model H face the same
direction. The scalp Ha of the head model H in the vicinity of the
upper part at one side of the head is an oblique upward curved
surface, as illustrated by a right-oriented downward line in FIG.
12(b), and when the one end part 72a of the hair measurement tool
70 is pressed against this upward curved surface of the scalp Ha,
because of the shape of the concave part 73 of the one end part
72a, the attitude of the hair measurement tool 70 is substantially
directed in the horizontal direction.
[0103] Furthermore, when the length of a hair bundle h54, implanted
in the vicinity of the left part at the top of the head model H, is
measured, the one end part 72a of the hair measurement tool 70 is
pressed against the scalp Ha in a state in which the one surface
72e and the front of the head model H face the same direction. The
scalp Ha of the head model H in the vicinity of the left part at
the top of the head is an oblique upward curved surface, as
illustrated by a right-oriented downward line in FIG. 12(b), and
when the one end part 72a of the hair measurement tool 70 is
pressed against this upward curved surface of the scalp Ha, because
of the shape of the concave part 73 of the one end part 72a, the
attitude of the hair measurement tool 70 is substantially directed
in the vertical direction.
[0104] In addition, when the length of a hair bundle h55, implanted
in the vicinity of the right part at the top of the head model H,
is measured, the one end part 72a of the hair measurement tool 70
is pressed against the scalp Ha in a state in which the other
surface 72f and the front of the head model H face the same
direction. The scalp Ha of the head model H in the vicinity of the
right part at the top of the head is an oblique upward curved
surface, as illustrated by a left-oriented downward line in FIG.
12(b), and when the one end part 72a of the hair measurement tool
70 is pressed against this upward curved surface of the scalp Ha,
because of the shape of the concave part 73 of the one end part
72a, the attitude of the hair measurement tool 70 is substantially
directed in the vertical direction.
[0105] And furthermore, when the length of a hair bundle h56,
implanted in the vicinity of the right upper part of the head model
H, is measured, the one end part 72a of the hair measurement tool
70 is pressed against the scalp Ha in a state in which the one
surface 72e and the front of the head model H face the same
direction. The scalp Ha of the head model H in the vicinity of the
upper part at the right side of the head is an oblique upward
curved surface, as illustrated by a left-oriented downward line in
FIG. 12(b), and when the one end part 72a of the hair measurement
tool 70 is pressed against this upward curved surface of the scalp
Ha, because of the shape of the concave part 73 of the one end part
72a, the attitude of the hair measurement tool 70 is substantially
directed in the horizontal direction.
[0106] As described above, with the oblique one end part 72a, in a
state of being pressed against the head (scalp), since the attitude
of the hair measurement tool 70 of the seventh modification can be
aligned easily along a substantially vertical direction or a
substantially horizontal direction, the usage matching up with the
sense of direction of the user (beautician or barber) can be
realized.
[0107] FIGS. 13(a) to (c) illustrate a hair measurement tool 80 of
an eighth modification. The hair measurement tool 80 is formed by
an elongated plate member, made of synthetic resin having
flexibility capable of elastic deformation, so as to be warped in
the width direction (Y-axis direction). The plate thickness of the
hair measurement tool 80 is less than 1 mm, and as illustrated in
FIG. 13(a), when the user grasps both side surfaces 82c, 82d and
increases the grip strength so as to close the thumb and the index
finger together, then as illustrated in FIG. 13(b), an end surface
of one end part 82a elastically deforms so as to form a warped
shape (the hair measurement tool 80 as a whole becomes a gutter
shape by elastic deformation). Furthermore, when the grip strength
is reduced, it returns to a flat state. Moreover, the other parts
of the hair measurement tool 80 of the eighth modification are
substantially the same as those of the hair measurement tool 1 as
illustrated in FIG. 1, for example, with notches 84 formed on the
side surfaces 82c, 82d (a concave part is formed at the one end
part 82a placed on the scalp).
[0108] With the hair measurement tool 80 having the above
characteristics, in a warped state in the width direction as
illustrated in FIG. 13(c), when a hair bundle 60 as the length
measurement object is placed on one surface 82e, as compared with
the flat state, the hair bundle 60 will not drop easily from the
one surface 82e, and stable measurements can be performed.
Furthermore, in the warped state as described above, when the one
end part 82a of the hair measurement tool 80 is pressed against the
scalp of the head, since the end surface of the one end part 82a is
curved because of a concave part, both end parts and a center part
in the warped state, namely three points in total, come into
contact with the scalp, and as compared with the flat state, a more
stable pressed state can be secured, and also from this viewpoint,
stable measurements can be performed.
[0109] Moreover, as a further modification of the eighth
modification, the elongated member constituting the hair
measurement tool, maintaining the warped state, can be formed by
synthetic resin, and with this structure, as illustrated in FIG.
13(a), the hair measurement tool in the warped state, without
requiring grip strength, can be provided. Furthermore, when the
hair measurement tool in the warped state, not in the flat state,
is formed by synthetic resin, other than the warped state
(substantially in "U"-shape), a bent state (deflected to form a
substantially "V"-shaped bent) can also be formed, and in addition,
modifications with various depths of warp (or bent) can be
provided.
[0110] FIGS. 14(a) to (c) illustrate a hair measurement tool 90 of
a ninth modification. The hair measurement tool 90 is formed by a
plate member elongating in the length direction (X-axis direction),
in a state of being folded along the length direction. In
particular, a first plate part 91 as one part to be folded over,
and a second plate part 92 as another part, are connected by one
side part 99 elongated in the length direction (a side part on the
connecting side of folding over), and the side surfaces 91c, 92d of
the respective plate parts 91, 92, namely the side parts on the
other side (the side parts on the opening side), can be opened and
closed by making the one side part 99 the pivot. The hair
measurement tool 90 with this structure is formed integrally by
synthetic resin, and since the one side part 99 connecting both
parts 91, 92 has a hinge-like flexibility, the one side part 99
elastically deforms so as to allow opening and closing of both
parts 91, 92.
[0111] The structure of each of the plate parts 91, 92 is
essentially equivalent to the hair measurement tool 70 of the
seventh modification as illustrated in FIGS. 11(b) and 11(c), with
a concave part 93 at one end parts 91a, 92a, also with scale lines
in solid lines and intermediate scale lines in dashed lines
indicated on one of surfaces 91e, 92e and another one of surfaces
91f, 92f, and with notches 94 formed on one of the side surfaces
91c, 92c.
[0112] Furthermore, on the other side surfaces 91d, 92d connecting
the first plate member 91 and the second plate member 92, the one
side part 99 is substantially formed in a slim stick shape, and
notches 94 are also formed in this one side part 99 corresponding
to each of the positions of the scale lines in solid lines as
described above (see FIG. 14(b)).
[0113] And furthermore, for the purpose of maintaining the closed
state of the first plate part 91 and the second plate part 92, the
hair measurement tool 90 has a locking mechanism. The locking
mechanism is composed of stick-shaped projections 91g projecting
from the other surface 91f in the vicinity of the one end part 91a
and in the vicinity of the other end part 91b of the first plate
part 91, and locking holes 92g formed in the second plate part 92
so as to face these projections 91g, respectively. The hole
diameter of the locking hole 92g and the outer diameter of the
projection 91g are determined according to the size relationships
of the so-called "transition fit" or "interference fit" in the
field of "fitting" in machine design. Accordingly, when the
projections 91g, respectively formed in the vicinity of the one end
part 91a and in the vicinity of the other end part 91b, are
inserted into the locking holes 92g, respectively formed in the
vicinity of the one end part 92a and in the vicinity of the other
end part 92b, the projections 91g are fit into (locked by) the
locking holes 92g, and the first plate part 91 and the second plate
part 92 are folded over and achieve an integrated state (see FIG.
14(b) and the drawing on the left of FIG. 14(c)).
[0114] Furthermore, from the closed state of the first plate part
91 and the second plate part 92, when each of the side surfaces
91c, 92c is open, the projections 91g come out of the locking holes
92g, and the first plate part 91 and the second plate part 92 are
open by making the one side part 99 as the pivot, and the cross
section thereof in the width direction becomes a "V" shape (see
FIG. 14(c)).
[0115] Regardless of whether it is open or closed, the hair
measurement tool 90 of the ninth modification as described above
can be used for hair length measurement, for example, and in the
closed state, it is possible to use in substantially the same
manner as the hair measurement tool 70 of the seventh modification,
as illustrated in FIGS. 11(b) and 11(c) as well as in FIGS. 12(a)
and 12(b).
[0116] Furthermore, FIG. 15 illustrates a state in which the one
end parts 91a, 92a of the hair measurement tool 90 in the open
state are pressed against the scalp Ha in the vicinity of the neck
at the back of the head of the head model H. In this case, since
the hair measurement tool 90 is open, at the one end parts 91a, 92a
pressed against the scalp Ha, the two end parts of a curved oblique
side part 93 on the sides of the side surfaces 91c, 92c, and the
end surface of the one side part 99, for a total of three points,
come into contact with the scalp Ha. Therefore, the hair
measurement tool 90 in the pressed state will not be shaken in the
upward/downward or right/left directions (the directions of the
white arrows of FIG. 15), thus a stable attitude can be maintained,
and more stable length measurements can be performed.
[0117] In addition, in the open state of the "V"-shape, since the
hair or hair bundle as the measurement object can be accommodated
in a space between the first plate part 91 and the second plate
part 92, the drop-off of the hair or hair bundle as the measurement
object can be prevented, and a stable measurement can be performed.
Moreover, since the one end parts 91a, 92a of the hair measurement
tool 90 of the ninth modification form the curved oblique side part
93, like the case of the hair measurement tool 70 of the seventh
modification as illustrated in FIGS. 12(a) and 12(b), it is also
possible to be pressed against the head in the attitude aligning
with the vertical direction or the horizontal direction, whereby a
usage consistent with the sense of direction of the user
(beautician or barber) can be realized.
[0118] FIGS. 16(a) and 16(b) illustrate a hair measurement tool 100
according to a tenth modification. As compared with the hair
measurement tool 70 of the seventh modification of FIGS. 11(b) and
11(c), the hair measurement tool 100 has a form in which the curved
parts are modified to be straight. Namely, with reference to the
hair measurement tool 100, one end part 102a is formed as a mere
oblique straight line part 103, and no concave is formed at a
center part 103a (moreover, although the angle of the oblique
straight line part 103 to side surfaces 102c, 102d is 45 degrees,
the angle is not limited to this value).
[0119] Furthermore, scale lines 106 and intermediate lines 107
indicated on one surface 102e of the hair measurement tool 100 are
also oblique straight lines parallel to the oblique straight line
part 103 of the one end part 102a. These scale lines 106 and the
intermediate scale lines 107 are indicated on the one surface 102e
from the one end part 102a to another end part 102b, and
discontinue at the other end part 102b, since the other end part
102b is in a straight line perpendicular to side surfaces 102c and
102d. Moreover, another surface on the reverse side of the one
surface 102e of the hair measurement tool 100 is substantially the
same as the one surface 102e, and notches 104 are formed on the
side surfaces 102c, 102d, at the positions corresponding to the
scale lines 106, like the cases as described above.
[0120] Since the scale lines 106 and the intermediate scale lines
107 of the hair measurement tool 100 are straight oblique lines,
the user can intuitively determine the cut length without
difficulties, and this is suitable for users who cannot manage the
hair measurement tool 70 of the seventh modification.
[0121] FIGS. 17 through 21 illustrate a hair measurement tool 110
according to an eleventh modification, as a further modification of
the hair measurement tool 70 of the seventh modification of FIGS.
11(b) and 11(c), suitable for hair length measurement, for example,
along an angular direction of a desired hair setting. Namely, as
illustrated in FIGS. 17(a) and 17(b), one end part 112a of an
elongated member 112 of the hair measurement tool 110 according to
the eleventh modification is aligned with an imaginary oblique line
K1 at an angle of 45 degrees to the X axis as illustrated in FIG.
17(c) (when referring to the hair measurement tool 70 of FIGS.
11(a) and 11(b) as the standard, corresponding to 135 degrees
relative to the X axis), and a curved concave part 113 is formed so
that an approximate center 113a is the innermost part, and in
addition, at an end part 113b on the side of one side surface 112d,
the curve direction changes to form a projecting curve. Therefore,
the one end part 112a has a combined curved line, composed of a
recessing curved line of the concave part 113, and a projecting
curved line of the end part 113b of the one side surface 112d,
connected at the inflection point, so that the imaginary straight
oblique line K1 is tangent to the one end part 113b and another end
part 113c. Moreover, as illustrated in FIG. 17(a), the hair
measurement tool 110 has a mark 114 indicating that the angle
relative to the one end part 112a is 45 degrees, on one surface
112e in the vicinity of the one end part 112a.
[0122] As illustrated in FIG. 17(a), scale lines 116 and
intermediate scale lines 117, in the same curve as that of the one
end part 112a, are indicated on the one surface 112e of the hair
measurement tool 110. These scale lines 116 and the intermediate
scale lines 117 are indicated with predetermined intervals from the
one end part 112a to another end part 112b, like the case of the
other embodiment and modifications as described above. Moreover,
the hair measurement tool 110 indicates a center line 119 from the
one end part 112a to the other end part 112b, at the center in the
width direction of the one surface 112e. And furthermore, distances
from the one end part 112a are indicated on each of the scale lines
116 of the hair measurement tool 110, on both sides as seen from
the center line 119.
[0123] Furthermore, as illustrated in FIG. 17(b), the shape of the
other end part 112b of the hair measurement tool 110 is based on an
inclined angle different from that of the one end part 112a.
Namely, as illustrated in FIG. 18(c), the other end part 112b of
the hair measurement tool 110 is aligned with an imaginary oblique
line K2 at the angle of 22.5 degrees to the X axis, and a curved
concave part 118 is formed so that an approximate center 118a is
the innermost part, and at an end part 118b on the side of the
other side surface 112c, the curve direction changes to form a
projecting curve. Since this shape of the other end part 112b on
the one surface 112e is different from the curved lines of the
scale lines 116 and the intermediate scale lines 117 as described
above, an area without indication of the scale lines 116 or the
intermediate scale lines 117 exists in proximity to the other end
part 112b on the one surface 112e. Moreover, FIG. 17(b) illustrates
the vicinity of the other end part 112b as seen from the one
surface 112e, while FIG. 18(c) illustrates the vicinity of the
other end part 112b as seen from another surface 112f.
[0124] As described above, the other end part 112b has a combined
curved line, composed of a recessing curved line of the concave
part 118, and a projecting curved line of the end part 118b of the
other side surface 112c, connected at the inflection point, so that
the imaginary straight oblique line K2 is tangent to the one end
part 118b on the side of the other side surface 112c and another
end part 118c on the side of the one side surface 112d (see FIG.
18(c)).
[0125] Furthermore, as illustrated in FIGS. 18(a) and 18(b), the
other surface 112f of the hair measurement tool 110 indicates scale
lines 116' and intermediate scale lines 117' in the same curve as
that of the other end part 112b. The scale lines 116' and the
intermediate scale lines 117' are indicated with predetermined
intervals from the other end part 112b to the one end part 112a,
showing distances from the other end part 112b on each of the scale
lines 116', on both sides as seen from the center line 119.
Moreover, as illustrated in FIG. 18(b), the hair measurement tool
110 has a mark 114' indicating that the angle to the other end part
112b is 22.5 degrees, on the other surface 112f in the vicinity of
the other end part 112b. Moreover, since the shape of the curved
lines of the scale lines 116' and the intermediate scale lines 117'
as described above are different from the shape of the one end part
112a, as illustrated in FIG. 18(a), an area without indication of
the scale lines 116' or the intermediate scale lines 117' exists in
proximity to one end part 112a on the other surface 112f.
[0126] FIG. 19(a) illustrates a plurality of first through third
angled lines 115a-115c, respectively indicated at the center
between the one end part 112a and the other end part 112b on the
one surface 112e of the hair measurement tool 110. The first angled
line 115a is a straight line perpendicular to the center line 119
(parallel to the Y axis); the second angled line 115b is a straight
line inclined at an angle of 45 degrees to the center line 119, and
the third angled line 115c is a straight line inclined at an angle
of 45 degrees to the center line 119 on the side opposite to the
second angled line 115b (the third angled line 115c and the second
angled line 115b are symmetrical with respect to the center line
119, and the third angled line 115c is parallel to the imaginary
oblique line K1 as illustrated in FIG. 17(c)). The first, second,
and third angled lines 115a-115c are indicated at three positions
in total on the one surface 112e with intervals, in particular, at
positions of about 140 mm, about 240 mm, and at about 340 mm,
respectively, from the one end part 112a, and at these three
positions, the direction along which hair is picked can be
confirmed by the first, second, and third angled lines
115a-115c.
[0127] FIG. 19(b) illustrates a plurality of first through seventh
angled lines 115a-115g, respectively indicated at the center
between the one end part 112a and the other end part 112b on the
other surface 112f of the hair measurement tool 110. The first
through third angled lines 115a-115c are the same as those on the
one surface 112e as described above. Furthermore, the fourth angled
line 115d is a straight line inclined at an angle of 22.5 degrees
to the center line 119 (parallel to the imaginary oblique line K2
as illustrated in FIG. 18(c)), the fifth angled line 115e is a
straight line inclined at an angle of 67.5 degrees to the center
line 119, the sixth angled line 115f is a straight line inclined at
an angle of 112.5 degrees to the center line 119, and the seventh
angled line 115g is a straight line inclined at an angle of 157.5
degrees to the center line 119. Moreover, the fourth angled line
115d and the fifth angled line 115e, and the seventh angled line
115g and the sixth angled line 115f, are symmetrical, respectively,
with relation to the center line 119. The first through seventh
angled lines 115a-115g are indicated at three positions in total on
the other surface 112f with intervals, in particular, at positions
of about 80 mm, about 180 mm and at about 330 mm, respectively from
the other end part 112b, and at these three positions, the
direction along which hair is picked can be confirmed by the first
through seventh angled lines 115a-115g.
[0128] Moreover, for the purpose of avoiding complicated drawings,
FIGS. 17(a) and 17(b) as well as FIGS. 18(a) and 18(b), as
described above, omit the illustration of 1-mm unit scale lines,
and each of the various scale lines is not illustrated in FIG.
17(c), FIG. 18(c) as well as FIGS. 19(a) and 19(b). Furthermore,
unlike the hair measurement tool 70 of the seventh modification of
FIGS. 11(b) and 11(c) as described above, since the hair
measurement tool 110 according to the eleventh modification does
not form notches for positioning the crest of hairdressing
scissors, the elongated member 112 uses a thin material at a
thickness of 1 mm for the purpose of weight saving (it is of course
possible to form notches in the hair measurement tool 110 of the
eleventh modification, like the case of the hair measurement tool
70 of the seventh modification).
[0129] FIGS. 20(a) and 20(b) illustrate states in which the hair
measurement tool 110 of the eleventh modification is used for the
head model H. FIG. 20(a) is a view as seen from the side of the
head model H, showing the state in which the one end part 112a of
the hair measurement tool 110 is pressed against (placed on) the
scalp Ha of the head model H. For example, when the hair bundle
h61, implanted in the vicinity of the neck at the back of the head
of the head model H, is measured, for the purpose of coordinating
with the natural direction of hair implantation (backward
direction), the one end part 112a of the hair measurement tool 110
is pressed against the scalp Ha in a state in which the one surface
112e and the side of the head model H face the same direction. At
that time, since the concave part 113 is formed at the one end part
112a, the end parts 113b and 113c as illustrated in FIGS. 17(a) and
17(c), namely the two points come into contact with the scalp Ha,
thus the hair measurement tool 110 in a pressed state is maintained
in a stable attitude, and the accurate measurement can be
performed.
[0130] Here, as illustrated by the imaginary oblique line K1 of
FIG. 17(c), since the one end part 112a is inclined at an angle of
45 degrees to the X axis, the length measurement at an angle of 45
degrees to the curved surface of the scalp Ha, into which the hair
bundle h61 is implanted, can be performed easily, and when a
desired hair set direction is at an angle of 45 degrees to the
scalp Ha, an accurate length measurement relative to the hair set
direction can be performed. In this case, since the direction at an
angle of 45 degrees to the scalp position, against which the hair
measurement tool 110 is pressed, is along the direction of the
center line 119, an angle of 45 degrees to the scalp can be
understood easily by looking at the center line 119. Furthermore,
with the first through third angled lines 115a-115c as illustrated
in FIG. 19(a), with reference to the inclined direction at an angle
of 45 degrees as the standard (the center line 119 serves as the
standard line), the angles of 45 degrees and 135 degrees relative
to the standard (the center line 119 as the standard line) can be
determined by the second angled line 115b and the third angled line
115c, and the direction of picking the hair bundle along various
angular directions can be measured accurately.
[0131] In addition, also in the case of measuring a hair bundle h62
implanted in the vicinity of the rear at the top of the head of the
head model H, like the case as described above, the one end part
112a of the hair measurement tool 110 is pressed against the scalp
Ha. Also in this case, similarly as above, the length measurement
in the direction at an angle of 45 degrees to the curved surface of
the scalp Ha, into which the hair bundle h62 is implanted, can be
performed securely.
[0132] Furthermore, when the lengths of the hair bundles h63, h64,
respectively implanted in the vicinity of the front at the top of
the head model H, are measured, for the purpose of coordinating
with the direction of hair implantation (forward direction), the
one end part 112a of the hair measurement tool 110 is pressed
against the scalp Ha in a state in which the other surface 112f and
the side of the head model H face the same direction. Accordingly,
the length measurement in the direction at an angle of 45 degrees
to the curved surface of the scalp Ha, into which the hair bundles
h63, h64 are implanted, can be performed securely. Moreover,
further in this case, it is also possible to understand various
angular directions by the angled lines 115a-115g indicated on the
other surface 112f. Moreover, unlike the direction of hair
implantation, in the case of stand-up hair setting, in a state
where the one surface 112e and the side of the head model H face
the same direction, the one end part 112a is pressed against the
positions of the scalp Ha into which the hair bundles h63, h64 are
implanted.
[0133] Meanwhile, FIG. 20(b) is a view as seen from the front of
the head model H, and when taking into account the hair set
direction after haircut, the measurement is performed in a state
where the one surface 112e or the other surface 112f of the hair
measurement tool 110, and the front of the head model H, face the
same direction. For example, when the length of a hair bundle h71,
implanted in the vicinity of the left side of the head of the head
model H, is measured, in order to coordinate with the
downward-oriented hair, the one end part 112a of the hair
measurement tool 110 is pressed against the scalp in a state where
the one surface 112e and the front of the head model H face the
same direction. With the concaved part 113 of the one end part
112a, the hair measurement tool 110 maintains a stable attitude,
whereby length measurements at an angle of 45 degrees relative to
the curved surface of the scalp position, into which the hair
bundle h71 is implanted, can be performed.
[0134] Furthermore, in regard to the other hair bundles h72, h73
and h74, the one end part 112a of the hair measurement tool 110 is
pressed against the scalp in a state where the one surface 112e or
the other surface 112f, and the front of the head model H, face the
same direction. Accordingly, a length measurement at an angle of 45
degrees relative to the curved surfaces of the scalp positions,
into which the hair bundles h72, h73 and h74 are implanted
respectively, can be performed. Moreover, in the case of stand-up
hair setting after a haircut, the one end part 112a of the hair
measurement tool 110 may be pressed against the scalp in a state
where the one surface 112e or the other surface 112f, and the front
of the head model H, face the same direction, unlike the state as
illustrated in FIG. 20(b) (for example, when the stand-up hair set
of the hair bundle h72 is performed, the one end part 112a of the
hair measurement tool 110 is pressed against the scalp in a state
where the other surface 112f faces forward toward the head).
[0135] Moreover, although FIGS. 20(a) and 20(b) respectively
illustrate the state where the one end part 112a of the hair
measurement tool 110 is pressed against the scalp, when the hair is
set after a haircut so that it traces the shape of the scalp, it is
preferable to press the other end part 112b against the scalp. In
this case, as illustrated in FIG. 18(c), since the other end part
112b is inclined at an angle of 22.5 degrees, the length
measurement at an angle of 22.5 degrees to the curved surface of
the scalp at the pressed position, can be performed (the direction
at the angle of 22.5 degrees to the pressed position can be
confirmed by the center line 119).
[0136] FIGS. 21(a) and 21(b) are views as seen from the top of the
head model H, showing states in which the one end part 112a or the
other end part 112b is pressed against the scalp Ha. Namely, FIG.
21(a) illustrates the states in which the one end part 112a of the
hair measurement tool 110 is pressed against the scalp Ha, wherein
the one surface 112e of the hair measurement tool 110 and the top
of the head model H face the same direction for hair bundles h81,
h84 at cater-cornered positions, and the other surface 112f and the
top of the head model H face the same direction for hair bundles
h82, h83 at the other cater-cornered positions. By pressing the
hair measurement tool 110, the length measurement at an angle of 45
degrees, namely in the natural hair direction, can be performed at
the implanted position of each of the hair bundles h81 through h84
(the direction at an angle of 45 degrees is the direction of the
center line 119).
[0137] Furthermore, FIG. 21(b) illustrates states in which the
other end part 112b of the hair measurement tool 110 is pressed
against the scalp Ha, wherein the one surface 112e of the hair
measurement tool 110 and the top of the head model H face the same
direction for hair bundles h91, h93 at cater-cornered positions,
and the other surface 112f and the top of the head model H face the
same direction for hair bundles h92, h94 at the other
cater-cornered positions. By pressing the hair measurement tool
110, a length measurement at an angle of 22.5 degrees can be
performed at the implanted position for each of the hair bundles
h91 through h94 (the direction at an angle of 22.5 degrees is the
direction of the center line 119).
[0138] As described above, since the inclined angles of the one end
part 112a and the other end part 112b of the hair measurement tool
110 of the eleventh modification are different, the length
measurement at two angles (for example, 45 degrees and 22.5
degrees) relative to the scalp can be performed by appropriately
changing the side that is pressed against the scalp (see the
pressing states of FIG. 21(a) and the pressing states of FIG.
21(b)). Furthermore, when the one surface 112e and the other
surface 112f are reversed appropriately, the length measurement can
be performed at two more angles relative to the scalp (for example,
135 degrees against the above 45 degrees, and 157.5 degrees against
the above 22.5 degrees) (see FIGS. 20(a) and 20(b)). Besides, with
reference to each of the angled lines 115a-115g and the center line
119 indicated on the one surface 112e and the other surface 112f,
various angles can be confirmed, whereby various directions to pick
up hair as the length measurement object can be confirmed.
[0139] FIGS. 22(a) and 22(b) illustrate a hair measurement tool 120
according to a twelfth modification of the present invention. The
hair measurement tool 120 is a modification of the hair measurement
tool 1 according to the embodiment of FIG. 1, characterized by
another concave part (auxiliary concave part 131) that is formed at
an approximate center part 122g of one side surface 122c in the
length direction of an elongated member 122 (corresponding to one
part of a peripheral part of the elongated member). This auxiliary
concave part 131 is an arc-shaped (fan-shaped) cutout of the
approximate center part 122g, and the curvature of the arc is
equivalent to that of a concave part 123 formed at one end part
122a, and it is also desirable, for example, to be equivalent to
the curvature around the human neck (R=100, for example).
[0140] Furthermore, as illustrated in FIG. 22(a), the hair
measurement tool 120 indicates a protractor mark 125 above the
auxiliary concave 131 on the one surface 122e, and also indicates a
plurality of angled lines 125a-125g (corresponding to auxiliary
angled lines) in accordance with this protractor mark 125. Each of
the angled lines 125a-125g indicates the same angle as that of each
of the angled lines 115a-115g illustrated in FIG. 19(b), and the
intersection of the angled lines 125a-125g coincides with the
center of the protractor mark 125, and also coincides with the apex
of the auxiliary concave part 131. Furthermore, the hair
measurement tool 120 indicates a center line 129 on the one surface
122e showing the center in the width direction, and also indicates
angle marks 124 (an angle of 90 degrees relative to the length
direction of the X axis) for the one end part 122a.
[0141] And furthermore, the other end part 122b of the hair
measurement tool 120 is in a straight-line shape along the Y-axis
direction. Furthermore, the parts other than described above on the
one surface 122e of the hair measurement tool 120 are equivalent to
those of the embodiment and modification as described above. In
particular, like the case of FIG. 9(c), width scale lines 114 are
indicated, and curved scale lines 126 that are substantially the
same as those of FIG. 2(a), for example, are indicated (FIGS. 22(a)
and 22(b) omit the indication of various scale lines, such as
intermediate scale lines, and distances, for example). Moreover,
other than those as illustrated in FIGS. 2(a) and 2(c), the
distances from the one end part 122a may be indicated, for example,
both on the side of one side surface 125c and on the side of
another side surface 125d for the scale lines 126, and each of the
values is indicated symmetrically by designating the center line
129 as the symmetrical center. With the indication of values in
this direction, the distance can be confirmed by the value on any
one side, regardless of whether it is viewed at the side surface
125c or 125d. Moreover, the distances regarding the intermediate
scale lines may also be indicated along the center line 129.
[0142] FIG. 22(b) illustrates another surface 122f of the hair
measurement tool 120. Basically, the other surface 122f also has
scale lines as illustrated in FIG. 9(a), with the indication of
width scale lines 114' and straight scale lines 126'. Moreover, the
center line 129 elongating in the X-axis direction at the center in
the width direction is also indicated, and although not
illustrated, distances from the other end part 122b are indicated
corresponding to the scale lines 126', like the case of the one
surface 122e.
[0143] Furthermore, the hair measurement tool 120 indicates a
protractor mark 125' showing concentric arcs with predetermined
intervals, for the arc-shaped curve line of the auxiliary concave
part 131 formed at the approximate center part 122g in the length
direction, and a plurality of angled lines 125a'-125g'
(corresponding to auxiliary angled lines) in dashed lines are
indicated in accordance with the center of the protractor mark
125'. The angles of the angled lines 125a'-125g' are equivalent to
those of the angled lines 125a-125g indicated on the one surface
122e. Moreover, the angled line 125a' coincides with the scale line
126' at the position in the vicinity of the approximate center part
122g.
[0144] In addition, the hair measurement tool 120 also indicates an
auxiliary protractor mark 132 in the vicinity of the one end part
122a on the other surface 122f, and also indicates angled lines
132b-132g, respectively elongating from the center of the auxiliary
protractor mark 132. The angles of the angled lines 132b-132g are
the same as those of the angled lines 125b-125g described above.
Based on the angled lines 132b-132g, the hair measurement tool 120
can perform measurements related to haircut direction also at the
one end part 122a. Moreover, the hair measurement tool 120
according to the twelfth modification has no notch on either side
surface for the positioning of hairdressing scissors, and the
thickness of the elongated member 122 made of synthetic resin,
constituting the hair measurement tool 120, is about 1 mm.
[0145] Like the cases of FIGS. 4 and 5, the hair measurement tool
120 can stably measure the length of the hair bundle with the
two-point contact of both end parts 123b, 123c of the concave part
123 by pressing the one end part 122a against each part of the
scalp. Furthermore, even in the pressed state, the angle of the
hair bundle (the direction along which the hair bundle is picked)
can be confirmed by the angled lines 132b-132g and the center line
129 indicated on the other surface 122f, and in particular, the
direction perpendicular to the pressed part of the scalp can be
confirmed by the center line 129, and furthermore, the length can
be measured by taking into account the haircut and hair setting
direction by the angled lines 132b-132g.
[0146] Furthermore, as illustrated in FIGS. 23(a) and 23(b) as well
as in FIG. 24(a), the hair measurement tool 120 according to the
twelfth modification can measure the angular direction of hair
easily and more stably. Namely, when the auxiliary concave part
131, provided at the approximate center part 122g in the length
direction, is placed on the scalp Ha of the head model H, based on
each of the angled lines 125a-125g indicated on the one surface
122e or each of the angled lines 125a'-125g', indicated on the
other surface 122f, the measurement of haircut direction
(measurement of hair angle) can be performed.
[0147] When the auxiliary concave part 131 is placed, as compared
with the case where the one end part 122a is placed, since the
angled lines 125b, 125c, 125f, 125g, 125b', 125c', 125f and 125g',
respectively extending in the lateral direction at an angle of 22.5
degrees or 45 degrees, are indicated by lines, which are longer
than the angled lines 132b, 132c, 132f and 132g indicated on the
one end part 122a at the same angles, it is advantageous that the
angle can be measured more easily with longer lines. In addition,
when the auxiliary concave part 131 is placed, since the dimensions
are pressed along the width direction of the hair measurement tool
120, the dimensions become considerably shorter than in the case of
pressing one end part 122a, and therefore, the hair as the
measurement object can be picked up easily without interference by
the hair measurement tool 120. Furthermore, when the auxiliary
concave part 131 of the hair measurement tool 120 in the direction
corresponding to the back of the head, as illustrated in FIG.
24(a), is placed on the back of the neck (scruff), the direction of
the hair neckline (the direction of hair tips), for example, can be
measured by the angled lines 125a-125g and 125a'-125g'.
Furthermore, with the hair measurement tool 120 in the direction
corresponding to the front of the head as illustrated in FIG.
24(a), the direction of each of hair panels (the direction of the
hair tips) forming the front hair can also be measured by the
angled lines 125a-125g and 125a'-125g'.
[0148] Besides, when the auxiliary concave part 131 is placed,
since the hair measurement tool 120 is set in a connective attitude
to the curved surface of the scalp, as compared to the attitude
projecting in the normal line direction of the curved surface of
the scalp when the one end part 122a is pressed (see FIGS. 4 and 5,
for example), the user can handle the hair measurement tool 120
more easily.
[0149] And furthermore, as illustrated in FIG. 24(b), when the
auxiliary concave part 131 is placed on the scalp Ha, since both
end parts 131a, 131b of the auxiliary concave part 131 only come
into two-point contact, the hair measurement tool 120 will not
become unstable in a placed state, and the measurements can be
performed while positioned in a stable attitude. Accordingly, for
example, when the auxiliary concave parts 131 are placed on the
front, top and back of the head as seen from the side viewpoint of
FIG. 23(a), or when the auxiliary concave parts 131 are placed on
the left side, top and right side of the head as seen from the
front viewpoint of FIG. 23(b), or when the auxiliary concave parts
131 are placed on the front and back of the head as seen from the
top viewpoint of FIG. 24(a), the hair measurement tool 120 can
maintain a stable attitude, whereby more accurate angle
measurements can be realized. Moreover, with reference to FIG.
24(a), for the purpose of clearly understanding the direction of
the head, the drawing is prepared so that the eyes and the nose can
be seen through the auxiliary concave part 131 placed on the front
of the head.
[0150] Moreover, the structure of the hair measurement tool 1, as
well as those of the hair measurement tools 10-120 of the first
through twelfth modifications, may be combined arbitrarily. For
example, the intermediate notches 19 for the hair measurement tool
10 of the first modification, as illustrated in FIG. 8(a), may also
be applied to the hair measurement tools 20-120 of the second
through twelfth modifications. And besides, the notches 24 formed
on the whole circumferential surfaces for the hair measurement tool
20 of the second modification, as illustrated in FIG. 8(b), may
also be applied to the hair measurement tool 10 of the first
modification as well as to the hair measurement tools 30-120 of the
third through twelfth modifications. And furthermore, the comb part
51 of the hair measurement tool 50 of the fifth modification, as
illustrated in FIGS. 10(a) and 10(b), may also be applied to the
hair measurement tools 70-120 of the seventh through twelfth
modifications.
[0151] Furthermore, for the hair measurement tool 1 of FIG. 1, for
example, the hair measurement tools 10-120 of the first through
twelfth modifications, and the various combination examples
described above, as a whole, it is not necessary to indicate the
scale lines and the intermediate scale lines in the whole
circumferential surfaces, and they may be indicated only on the
necessary surfaces. In addition, when the elongated member
constituting the hair measurement tool is made of transparent
material, with the scale lines and the intermediate scale lines,
for example, indicated only on one surface, it is preferable that
the scale lines and the intermediate scale lines, for example, can
be confirmed from the other transparent surface, for example. And
in addition, for the hair measurement tool 1 of FIG. 1, for
example, the hair measurement tools 10-90 of the first through
ninth modifications, and the various combination examples described
above, as a whole, where the positioning (position restriction) of
the hairdressing scissors S as illustrated in FIG. 7(b), for
example, is not required and hair (hair bundle) length measurement
is the main application, the notches (and the intermediate notches)
as described above may be omitted. Furthermore, as the measurement
unit of the scale lines related to the length of the various hair
measurement tools 10-120, as described above, it is of course
possible to apply any unit other than mm or cm; for example,
English measurements can be applied. Furthermore, the combination
of different measurement system units may be also applied; for
example, the scale lines and sizes may be indicated by metric units
(mm) on the one side of the center line in the width direction,
while the scale lines and the sizes may also be indicated by
English units on the other side of the center line in the width
direction.
INDUSTRIAL APPLICABILITY

bundles) based on an objective index, and for haircut at a desired
length.
