Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a hair iron for curling,
and more particularly, to a wet-and-dry-type hair iron for curling,
which has a moisture discharge structure capable of curling hair in
a state where hair is wet when hair is curled by heating hair for
permanent wave of hair, thereby simultaneously carrying out hair
drying and curling when hair is curled just after washed.
[0003] Additionally, the present invention relates to a hair iron
for curling, which has a power line connection member capable of
idling and being freely attached and detached to preventing
twisting of a power line, thereby providing convenience in carrying
and arrangement.
[0004] 2. Background Art
[0005] In general, a hair iron for curling disclosed in Korean
Patent No. 0,562,426 (patented on Mar. 13, 2006) by the same
inventor as the present invention has been used in the beauty
industry and by the general public.
[0006] Typical hair irons are generally dry type hair irons for
curling dry hair in such a way that the entire of a heat generation
part is in contact with a customer's hair.
[0007] Therefore, if hair-forming is applied to wet hair, moisture
evaporated by heating cannot be discharged to the outside
smoothly.
[0008] So, when hair is heated to temperature necessary for forming
hair, hair-forming may be interfered since moisture hinders
temperature rising of the entire wet hair.
[0009] Furthermore, there are various prior arts related with a
cable anti-twisting structure of a power source line for electronic
appliances:
[0010] Korean Utility Model Publication No. 1990-0001560 (Feb. 28,
1990) entitled "Plug and jack of telephone for preventing twist of
wire";
[0011] Korean Utility Model Registration No. 0,165,033 (Oct. 13,
1999) entitled "Cord anti-twisting device of telephone";
[0012] Korean Utility Model Registration No. 0,167,150 (Oct. 30,
1999) entitled "Cord anti-twisting structure of handset";
[0013] Korean Patent Publication No. 1999-0021304 (Mar. 25, 1999)
entitled "Power cord anti-twisting structure of hair drier";
and
[0014] Korean Utility Model Publication No. 1998-0066628 (Dec. 5,
1998) entitled "Power cord for anti-twisting.
[0015] Most of the prior arts include a sleeve for receiving and
surrounding a cylindrical rotor to realize an anti-twisting
structure and an electric connection.
[0016] However, since such prior art anti-twisting structures
applied to various cables for a power line and a telephone line are
generally in a fixed type and cannot be attached and detached via a
plug and a jack, they are disadvantageous in packing, safekeeping
and carrying.
SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0034] Reference will be now made in detail to the preferred
embodiment of the present invention with reference to the attached
drawings. In the drawings, like reference numerals designate like
or similar parts.
[0035] FIG. 1 is a perspective view of a hair curling iron (I)
according to the present invention, and FIG. 2 is an exploded
perspective view showing a state where the hair curling iron (I) of
FIG. 1 is rotated at an angle of 180.degree..
[0036] As shown in the drawings, the hair curling iron (I)
according to the present invention includes: a main body 210; and a
lever 220 combined with the main body 210 through a rotary shaft
pin 222 at the boundary between a heat generation part 213 and a
grasping part 211.
[0037] The combination of the main body 210 and the lever 220 has a
form similar to scissors, but the lever 220 combined with the main
body 210 pivots on the rotary shaft pin 222 in such a way that the
heat generation part 213 of the main body 210 and a pressurizing
part 223 of the lever 220 engage with each other without crossing
each other.
[0038] Another hair curling iron (I) shown in FIG. 8 has the same
moisture discharge supporting member, anti-twisting structure, and
attaching and detaching concept as the iron shown in FIGS. 1 to 4,
which are the cores of the present invention, but has a different
lever structure from the iron of FIGS. 1 to 4. In FIG. 8, a lever
320 includes a pressing part 325 for pivoting a pressurizing part
323 on a rotary shaft pin 322 of a connection part 321, the
pressing part 325 being located in the same direction as the
pressurizing part 323 engaging with a heat generation part 312 of a
main body 310.
[0039] The rotary shaft pin 322 has a spring (not shown) mounted
therein so as to provide elasticity to always keep engagement
between the pressurizing part 323 of the lever 320 and the heat
generation part 313 of the main body 310 when the external force is
not applied.
[0040] The rotary shaft pins 222 and 322 shown in FIGS. 1 and 8
serve as rotary shafts for the levers 220 and 320, facilitate
assembly between the main body and the lever since they have
elasticity.
[0041] Moreover, each rotary shaft pin serves as a hanger for
allowing a user to hang the iron on a holder when the user does not
use the iron (I) but conducts other work, so that the user can do
other work freely and easily.
[0042] The grasping part 211 of the main body 210 has a idle tube
211A combined on the outer periphery of a central rod 211B in order
to easily wind hair on the heat generation part 213 of the main
body 210 for curling hair.
[0043] Moreover, the above function may be achieved by a idle
member 213A disposed at an end portion of the heat generation part
213 having an electric heating body 214 therein and a idle tube
225A disposed on the outer periphery of a central rod 225B at the
pressing part 225 of the lever 220.
[0044] The idle member 213A disposed on the end portion of the heat
generation part 213 has radial slots 213a.
[0045] Since hair can be inserted into the slot 213a, if the main
body 210 is rotated on the idle member in a state where the idle
member 213A is in contact with hair, the main body is rotated but
the idle member 213A is not rotated along with the main body by
hair inserted into the slots 213a, so that the user can more easily
wind hair on the heat generation part 213 of the main body 210.
[0046] Furthermore, the idle function may not be used according to
hair forming types.
[0047] Considering the above, the idle tube 211A of the grasping
part 211 of the main body 210 includes a locking member 212.
[0048] The locking member 212 includes: a button 212A formed
between the grasping part and the heat generation part in such a
way as to be freely moved by the user's thumb laterally; a fitting
hole (not shown) formed on the inner periphery of the idle tube
211A for inserting a fitting end portion (not shown) of the button
when the button is pushed toward the idle tube 211A; and a locking
position mark 212B formed on the outer periphery of the idle tube
for allowing the user to easily check a position of the fitting
hole of the idle tube (see FIG. 1).
[0049] For convenience in manipulation, a temperature control dial
215b and a power on/off button 215a (see FIG. 1) are formed at the
portion of the main body 210 on which the button 212A is
formed.
[0050] Next, another locking member 226 is formed on the idle tube
225A of the pressing part 225 of the lever 220.
[0051] The locking member 226 is mounted at a portion where two
symmetric brackets 221a of the connection part 221 of the lever 220
meet with each other, and includes: a guide rail 226B formed at a
start point of the central rod 225B of the pressing part; a guided
tube 226A laterally moving along the guide rail 226B in a state
where it is prevented from separation; and a corresponding joining
portion 225a formed at a portion of the inner periphery of the idle
tube 225A in such a way as to engage with a joining portion 226a of
the guided tube 226A in a form of male and female.
[0052] The idle tube 225A of the pressing part 225 of the lever 220
is assembled to the lever 220 in such a way that the idle tube 225A
is fit onto the central rod 225B and a tightening nut 225b' is
joined and tightened to a bolt 225b of an end portion of the
central rod 225B, whereby the idle tube 225A is close toward the
guided tube 226A.
[0053] The lever 220 is combined with the main body 210 in the
steps of inserting the main body 210 to the connection part 221
having the two brackets 221a, inserting and fitting both end
portions 222a of the rotary shaft pin, especially, elastic rotary
shaft pin 222, into holes 221b of the brackets 221a at the boundary
formed between the grasping part and the heat generation part of
the main body 210, and inserting the end portions of the rotary
shaft pin into two shaft pin insertion holes 213b of the heat
generation part 213 of the main body 210.
[0054] Therefore, when the user presses the pressing part 225, the
pressurizing part 223 pivots on the rotary shaft pin 222, and the
lever 220 engages with the heat generation part 213 of the main
body 210.
[0055] It is preferable that the pressurizing part 223 has
curvature corresponding to the heat generation part 213 of the main
body 210, and so, the inner surface of the pressurizing part 223 is
in contact with the entire surface of the heat generation part when
it engages with the heat generation part.
[0056] Like Korean Patent No. 056426 invented by the same inventor
as the present invention, to curl hair more rapidly by using heat
generated from the heat generation part and the electric heating
body of the main body, and to enhance hair curling quality by
transmitting heat uniformly to hair located between the
pressurizing part of the lever and the heat generation part of the
main body, it is preferable to embed an electric heating body 224
in the lever. For this, an electric wire 223b extending from a
power line 30 of a cord (c) must be extended from the heat
generation part 213 of the main body 210 to an electric wire 223b'
for the electric heating body 224.
[0057] The hair curling iron (I) according to the present invention
is characterized in that an auxiliary moisture discharge member 230
is arranged on the inner surface of the pressurizing part 223 of
the lever 220 to realize a wet-and-dry-type iron.
[0058] The auxiliary moisture discharge member 230 has a channel
231 formed in a longitudinal direction of the lever, whereby
moisture evaporated from wet hair by heating of the two electric
heating bodies 214 and 224 can be discharged to the air along the
channel.
[0059] Furthermore, the channel 231 of the auxiliary moisture
discharge member 230 has a number of through holes 233, and the
pressurizing part 223 of the lever 220 has discharge holes 223a
corresponding to the through holes 233, so that evaporated moisture
can be discharged more smoothly.
[0060] The auxiliary moisture discharge member 230 serves as a
cover for the electric heating body 224 of the pressurizing part
223 of the lever 220.
[0061] The form and the number of the channel and the through holes
may be changed by those skilled if necessary.
[0062] Next, anti-twisting means (T) of a power line connection
member (L) and attaching and detaching means (A) for attaching and
detaching the power line to and from the hair curling iron will be
described.
[0063] First, in the hair curling iron (I) shown in FIGS. 1 to 4,
the anti-twisting means (T) is mounted on the cord (C) having the
power line 30.
[0064] However, in the hair curling iron (I) shown in FIGS. 5 to 7,
the anti-twisting means (T) is mounted on the iron (I).
[0065] For your reference, the standard of directions of the
anti-twisting means and the attaching and detaching means will be
specified referring to FIGS. 1 and 3.
[0066] In the anti-twisting means formed by combination of an idle
projection member 10 and a socket 20, a direction that a jack 27 of
the socket 20 is coupled with a plug (L1) of the power line
connection member (L) of the iron (I) is defined as a front
direction, and the opposite direction of the front direction is
defined as a rear direction.
[0067] As shown in FIGS. 1 to 4, the idle projection member 20 of
the anti-twisting means (T) is connected with the power line 30 of
the cord (C).
[0068] The jack 27 of the socket 20 coupled with the idle
projection member 10 is coupled with the plug (L1) of the power
line connection member (L).
[0069] The jack 27 and the plug L1 constitute the attaching and
detaching means (A).
[0070] The power line 30 includes: a main plug formed at an end
portion thereof and coupled with a power socket (not shown)
equipped in a living room, a bath room, or another room,
particularly, a main plug 30A (see FIG. 1) for a three-phase power
source; a copper wire 31 (see FIG. 4); an insulating covering 33
surrounding the copper wire 31; and an outer covering 35 for
covering the insulating covering 33.
[0071] In FIGS. 3 and 4, the idle projection member 10 is disposed
at the other end portion of the main plug 30A and has two contact
members 13 and 15 arranged concentrically.
[0072] The two contact members 13 and 15 of the idle projection
member 10 are connected with each other in the form of a shape, and
a damage preventing bellows portion 10b and a hanger ring 10a are
formed at a bended portion of the connected area between the two
contact members 13 and 15. At this time, the damage preventing
bellows portion 10b is thicker than the outer covering 35.
[0073] The first contact member 13 of the idle projection member 10
is directly connected with the copper wire 31 of a straight power
line in a projection type.
[0074] Particularly, a projection 13A of the first contact member
13 is empty and serves as an insertion hole 13a for the copper wire
31. The copper wire 31 inserted into the projection 13A is fixed by
soldering, and is a conductor.
[0075] An insertion member 13B made of a non-conductor material and
serving to surround the projection 13A and hide the exposed copper
wire 31 may be formed in such a way as to mold melted synthetic
resin after inserting the projection 13A into an insertion hole 11a
of a housing 11, or previously formed with a separate member.
[0076] The insertion member 13B has a direction specifying slot 13b
corresponding to a direction specifying projection 11b of the
housing so as to help a firm fixation of the first contact member
13 coupled with the housing 11.
[0077] The second contact member 15 of the idle projection member
10 includes a ring type contact portion 15a and a connection piece
15b integrated with the contact portion.
[0078] The contact portion 15a is mounted on the outer periphery of
a mounting portion 11c of the housing 11, and the connection piece
15b is inserted into a fitting slot lid of the housing 11, and
then, the copper wire 31 of another power line is soldered to an
end portion of the connection piece 15b.
[0079] The housing 11 of the idle projection member 10 has the
insertion hole 11a for the first contact member 13 as described
above.
[0080] The front side of the insertion hole 11a has the shape and
inner diameter as large as the insertion hole 11a can accommodate
the projection 13A of the first contact member 13 in contact with
the projection 13A, and the rear side thereof has the size and
shape as large as the insertion hole 11a can accommodate the
remaining portion of the insertion member 13B excepting the outer
portion of the direction specifying slot 13b.
[0081] The housing 11 has a form for combining with cases 29A and
29B which are fixing means for restricting the coupled state
between the idle projection member 10 and the socket 20 while
allowing the idle projection member 10 and the socket 20 can be
rotated idly. For this, the housing 11 has a separation preventing
projection 11A formed on the front of the outer periphery thereof
and a separation preventing groove 11A' coupled with separation
preventing jaws 29b of the cases 29A and 29B.
[0082] Moreover, the housing 11 has a ring-shaped holding jaw 11B
and a holding groove 11B' formed at the rear thereof. An inward
projection type front end portion 10c extending from the damage
preventing bellow portion 10b of the idle projection member 10,
namely, extending from the outer covering 35 of the power line 30,
for preventing exposure of the connection state between the first
and second contact members 13 and 15 and the copper wire to provide
an insulation function is fit to the holding jaw 11B and the
holding groove 11B' so as to prevent separation of the idle
projection member 10 and the housing 11.
[0083] Next, referring to FIGS. 1 and 3, the socket 20 having first
and second coupling members 23 and 25 respectively connected with
the first and second contact members 13 and 15 of the idle
projection member 10 will be described.
[0084] The socket 20 has the jack 27 arranged at the front of a
socket body 21. The jack 27 is a typical jack generally used in
electronic appliances.
[0085] The jack 27 includes: contact sleeves 27a made of a
conductor material, each contact sleeve having an empty inside; and
fitting holes 27b to which a number of pins (L2) (two pins in the
drawings) of the plug (L1) of the power line connection member (L)
are inserted.
[0086] At the rear of the contact sleeves 27a, the first coupling
member 23 connected with the first contact member 13 of projection
type and the second coupling member 25 connected with the second
contact member 15 of ring type are respectively joined and arranged
through connection portions 23b and 25b.
[0087] Particularly, the first and second coupling members 23 and
25 are elastic pieces curved roundly and having elasticity, whereby
contact portions 23a and 25a for the first and second contact
members 13 and 15 of the idle projection member 10 surround the
outer periphery of each contact member.
[0088] As described above, the cases 29A and 29B as shown in the
drawing can fix the combination between the contact members 13 and
15 of the idle projection member 10 and the coupling members 23 and
25 of the socket 20, namely, prevent twisting of the cord by
guaranteeing a relative idle between the idle projection member and
the socket.
[0089] Particularly, to guarantee water-tightness between the
contact surfaces of the two cases 29A and 29B, one of the cases has
a projection (not designated in the drawing) and the other has a
recess (not designated) in such a way as to be coupled with each

housing 11 of the idle projection member 10 is formed at the rear
(left side in the drawing) of each case.
[0091] Moreover, an oval shaped separation preventing jaw 29c which
will be inserted into an oval shaped separation preventing groove
21a formed at the rear of the body 21 of the socket 20 is formed at
the front of each case (right side in the drawing).
[0092] A support flange 29a having a support recess 29a to which
the first contact member 13 of the idle projection member 10 is
inserted is formed between the separation preventing jaws 29b and
29c, so as to guarantee stable combination and idle between the
idle projection member and the socket.
[0093] For your reference, the reference numeral 29d in FIG. 3
designates a projection coupled with a recess 27c formed on the
outer periphery of the jack 27.
[0094] The separation preventing groove 21a of the body 21 of the
oval shaped socket 20 and the separation preventing jaw 29c of the
cases 29A and 29B function as mounting direction restricting means
for specifying an assembling direction of each part.

[0117] The connection piece 113b' is fit into the fitting hole 110d
of the housing 110 and soldered with another connection line 111c,
and the rear end portion of the connection line is also soldered
with another projection (L2a) of the plug (L1).
[0118] Next, referring to FIGS. 6 and 7, the intermediating means
120 having first and second coupling members 123 and 125 for the
first and second contact members 113A and 113B will be
described.
[0119] It is preferable that the intermediating means 120 is
mounted in a specified direction for easiness in assembly when it
is mounted on the hair curling iron.
[0120] For this, it is preferable to adopt mounting direction
restricting means to the intermediating means 120.
[0121] In the drawings, the mounting direction restricting means
includes a restricting piece 121a and two restricting projections
121b formed at the front of a body 121 thereof. Alternatively, the
mounting direction restricting means may be embodied by forming the
intermediating means in an oval shape.
[0122] The first coupling member 123 of the intermediating means
120 for the first contact member 113A is located at the front of a
mounting portion 121A of the intermediating means body 121, and the
connection piece 123a of the first coupling member 123 is exposed
forwardly from the outer periphery of the body 121 after passing
through a slit 121c of the body 121.
[0123] The front end portion of the connection piece 123a has a
connection hole 123a' to which a connection line 122 for
introducing electric power to the hair curling iron is inserted and
which is soldered.
[0124] The connection piece 123a has a fixed projection 123b
pressurized at a portion adjacent to the slit 121c of the body 121
so as to prevent separation of the first coupling member 123
coupled with the body 121.
[0125] The projection 113A of the first contact member 113A is
actually fit to a coupling portion 123B formed between two curved
pieces 123A of the first coupling member 123.
[0126] Additionally, the second coupling member 125 arranged on the
mounting portion 121A at the rear of the first coupling member 123
has a connection piece 125a having a connection hole 125a' formed
at the front end portion thereof. The connection line 122 is
inserted into the connection hole 125a' and soldered, and the
connection piece 125a is fit into the slit 121d of the body 121 of
the intermediating means 120 and exposed to the outside.
[0127] In addition, the second coupling member 125 has a fixed
projection 125b for preventing separation of the second coupling
member 125 from the body 121.
[0128] Furthermore, the second coupling member 125 actually coupled
with the second contact member 113B in such a way that the second
contact member is fit to a coupling portion 125B formed by two
curved pieces 125A.
[0129] Hereinafter, to more perfectly embody the anti-twisting
means (T) of the hair curling iron according to the present
invention, fixing means arranged on a contact surface between the
idle projection member 110 and the intermediating means 120 to
guarantee idle of the idle projection member to the intermediating
means and to provide resistance when the idle projection member is
separated from the intermediating means will be described.
[0130] In FIGS. 6 and 7, the fixing means 127 includes elastic
pieces 127A and 127B disposed on the body 121 of the intermediating
means 120.
[0131] The elastic pieces 127A and 127B are separated from each
other by cut portion 127b located between them.
[0132] To provide proper resistance when the idle projection member
is separated from the intermediating means, some elastic pieces, in
more detail, every second elastic piece, respectively have a
pressurizing projection 127a formed on the inner surface of the
elastic piece 127A.
[0133] In a state where the idle projection member and the
intermediating means are coupled with each other, the separation
preventing groove 110A' coupled with the pressurizing projection
127a of the elastic piece 127A is formed on the front part 110F of
the idle projection member.
[0134] As described above, the present invention can allow a user
to easily assemble and disassemble the idle projection member and
the intermediating means by the elastically pressurizing member
without using great power, and prevent accidents such as an
electric shock since it can be prevented that the idle projection
member is separated from the intermediating means during not
knowing even though the hair curling iron is shaken during the
use.
[0135] As described above, the wet-and-dry-type hair curling iron
according to the present invention, which includes the lever
engageably connected to the main body having the grasping part and
the heat generation part, has the auxiliary moisture discharge
member having the channel and the through holes introduced to the
pressurizing part engaging with the heat generation part of the
main body, thereby smoothly discharging vapor evaporated from wet
hair by heating.
[0136] Furthermore, the wet-and-dry-type hair curling iron has the
idly rotatable anti-twisting means introduced to the power line
connection member of the grasping part of the main body and the
attaching and detaching means of a jack and plug type, thereby
enhancing convenience in use.
[0137] Moreover, the wet-and-dry-type hair curling iron has an
electric heating body introduced to the pressurizing part of the
lever, thereby heating and curling hair more rapidly together with
an electric heating body disposed on the heat generation part of
the main body and enhancing a hair-forming quality by uniformly
transmitting heat to hair located between the pressurizing part of
the lever and the heat generation part of the main body.
[0138] Finally, if those skilled in the hair beauty field and the
general public use the wet-and-dry-type hair curling iron according
to the present invention, the hair curling iron can provide a rapid
hair curling performance of high quality since it can
simultaneously carry out hair drying and curling when hair is
curled just after washed.
[0139] The hair curling iron according to the present invention
which can prevent twisting of power connection line and allow the
user to freely attach and detach the power line provides
convenience in carrying and arrangement.
[0140] In this description, common and well-known technologies
related with the general hair curling iron is omitted, but those
skilled can guess and expect such common and well-know
technologies.
[0141] While the present invention has been described with
reference to the particular illustrative embodiments, it is not to
be restricted by the embodiments but only by the appended claims.
It is to be appreciated that those skilled in the art can change or
modify the embodiments without departing from the scope and spirit
of the present invention.
