Abstract
A hair iron can regulate the surface of hair with the surfaces of correctors and disperse force acting on cross sectional points of each hair that are in contact with the correctors. The hair iron has clamp arms and the correctors that are arranged on the clamp arms, to face each other, hold hair between them, and heat the hair. At this time, correcting surfaces hold and correct the hair. The correcting surface of one of the correctors is roughened with irregularities to increase contact points or contact areas with the hair and the correcting surface of the other corrector is formed to be smoother than the correcting surface.

hollow grips ribs 53. Theclamp arm 7 has aprojection 55 to face theother clamp arm 9 and theclamp arm 9 has arecess 57 to receive theprojection 55. Theprojection 55 abuts against the bottom of therecess 57, to function as a stopper. - The base ends 15 and 17 of the
clamp arms grips - Cross sections of the front ends 29 and 31 of the
clamp arms FIG. 6 that is an enlarged sectional view seen from arrows SA ofFIG. 2 .FIG. 7 is an enlarged plan view showing sections of thecorrectors divisional parts clamp arms front end 29 will mainly be explained and the explanation related to thefront end 29 is applied to the otherfront end 31. - The
front end 29 has, as shown inFIGS. 6 and 7 , flatvertical walls flat bottom wall 63 that contain acore 83. Thefront end 31 has vertical and bottom walls that are similar to the flatvertical walls bottom wall 63, to contain acore 85 of symmetrical shape. Thefront end 29 has acorrector support hole 65 to movably support thecorrector 11, so that thecorrector 11 may move toward and away from the other corrector. In thecorrector support hole 65, thecorrector 11 is movably supported. - The
correctors clamp arms clamp arms - The
corrector 11 has athermal plate 67, theceramic heater 69, amagnet plate 71, and afirst spring 73 and is pushed by asecond spring 75. - The
thermal plate 67 is made of a light-weight and highly heat conductive material such as aluminum and has a rectangular shape when seen from the opposite side. The back of thethermal plate 67 is integral with acasing 77 that is movably supported in thecorrector support hole 65 so that it can move toward and away from theother corrector 13. This back-and-forth moving support is also adopted by thecorrector 13. - Top and bottom walls of the
casing 77 havestoppers thermal plate 67 within a predetermined range. Theceramic heater 69,magnet plate 71, andfirst spring 73 are contained in thecasing 77. Namely, thecorrectors casing 77 behind thethermal plate 67 and thecasing 77 accommodates themagnet plate 71 serving as a magnet and thefirst spring 73 serving as a magnet pushing means to push themagnet plate 71 toward thethermal plate 67 relative to thecasing 77. Behind thethermal plate 67, themagnet plate 71 serving as a magnet is arranged along a correcting surface. In thecasing 77, there is arranged between the back of thethermal plate 67 and themagnet plate 71 theceramic heater 69 serving as a heat generator for carrying, out heat conduction to thethermal plate 67 from the back thereof. - The
ceramic heater 69 has a rectangular shape, generates heat up to about 180° C. at the maximum, conducts the heat to thethermal plate 67, and is electrically connected to thepower source cord 3. - The
magnet plate 71 is made of, for example, a neodymium magnet of 15000 gausses and has a rectangular plate shape. Themagnet plates 71 of thecorrectors magnet plates 71 may face each other. Themagnet plates 71 may be arranged so that their N-poles face each other. Themagnet plates 71 may be permanent magnets, electromagnets, or a combination of permanent magnet and electromagnet. It is preferred that themagnet plate 71 is of 10000 gausses or over. - Magnetic action of the
magnet plate 71 provides an ion effect and a low-frequency water activating effect. The ion effect magnetically generates negative ions. The low-frequency water activating effect is achieved by low-frequency oscillations of electromagnetic waves and electromagnetic fields around themagnet plate 71 and periodically vibrates water in hair to energize the water. The magnetic action also atomizes ambient water clusters so that the atomized water may easily permeate into hair. - The
first spring 73 is a plate spring that pushes themagnet plate 71 in thecasing 77 toward the back of thethermal plate 67, so that theceramic heater 69 is tightly attached to the back of thethermal plate 67. At the same time, it stably supports themagnet plate 71. The spring constant of thefirst spring 73 is set so that, when the opposingmagnet plates 71 are arranged with their S-poles facing each other, thefirst spring 73 may not bend due to the repulsive force of themagnet plates 71. - The
second spring 75 is supported at a rear end of thecasing 77. Thesecond spring 75 serves as a corrector pushing means to push thecorrectors correctors second spring 75 is a plate spring having inclined ends 75 a and 75 b whose edges engage with projections of thedivisional part 43 a in a left-right direction (longitudinal direction) ofFIG. 7 . - The details of the
correctors second springs FIGS. 8 to 12 .FIG. 8( a) is a front view showing the corrector,FIG. 8( b) a back view of the same,FIG. 8( c) a plan view of the same,FIG. 8( d) a sectional view of the same,FIG. 9( a) a sectional view showing essential part of a second correcting surface,FIG. 9( b) a sectional view showing essential part of a first correcting surface,FIG. 10( a) a sectional view showing a hair treating state according to the embodiment,FIG. 10( b) a sectional view showing a hair treating state according to a comparative example,FIG. 11( a) a plan view of the first spring,FIG. 11( b) a back view of the same,FIG. 12( a) a plan view of the second spring,FIG. 12( b) a front view of the same, andFIG. 12( c) a side view of the same. - As shown in
FIGS. 8( a) to 8(d), thethermal plates 67 of thecorrectors surfaces 87 that face each other. - As shown in
FIG. 9( a), the correctingsurface 87A of thecorrector 11 includes abase material 88A of aluminum (Al) whose surface is mirror-finished and a platinum (Pt)layer 90. Theplatinum layer 90 is plated to a thickness of about 0.01 μm. Between the surface of the base material 88 and theplatinum layer 90, a titanium dioxide (TiO2)layer 92 is formed. Between the surface of the base material 88 and thetitanium dioxide layer 92 and between thetitanium dioxide layer 92 and theplatinum layer 90, nickel (Ni) layers 94 and 96 are formed. - The correcting
surface 87B of one of thecorrectors surface 87A of the other thereof is formed to be smoother than the correctingsurface 87B. - Namely, only the correcting
surface 87A of thecorrector 11 is formed into a mirror state, and as shown inFIG. 9( b), the correctingsurface 87B is roughened with irregularities to increase contact points or contact areas with hair. - In connection with the correcting
surface 87B of thecorrector 13, the surface of the aluminum (Al)base material 88B is not mirror-finished but it is left as it is, or the surface roughness thereof is adjusted, and the platinum (Pt)layer 90 is arranged. Irregularities at the surface of theplatinum layer 90 of the correctingsurface 87B are in the range of 5 to 15 μm. - To adjust the surface roughness, irregular lines may be formed in a width direction of the correcting
surface 87B, i.e., in a direction to slide the correcting surface relative to hair to treat. For example, irregular lines are formed in a vertical direction ofFIG. 8( a). Irregular lines may obliquely be formed in a width direction of the correctingsurface 87B, or they may obliquely be curved. Irregularities may be formed into a reticulate state when seen from the front of the correctingsurface 87B. - The
platinum layer 90 of the correctingsurface 87B is plated to a thickness of about 0.01 μm like that of the correctingsurface 87A. Between the surface of the base material 88 and theplatinum layer 90, a titanium dioxide (TiO2)layer 92 is formed. Between the surface of the base material 88 and thetitanium dioxide layer 92 and between thetitanium dioxide layer 92 and theplatinum layer 90, nickel (Ni) layers 94 and 96 are formed. - The
platinum layer 90 has a water-retaining function and a catalytic function. The water-retaining function collects water from air and provides hair with the water. The catalytic function atomizes harmful substances and organic compounds. - The
titanium dioxide layer 92 has a photocatalytic function. This photocatalytic function converts the harmful substances atomized by theplatinum layer 90 into harmless water and carbon dioxide. In addition, the titanium dioxide layer provides an ion effect to generate negative ions to neutralize the harmful substances. - The
nickel layer 94 prevents oxidization of the aluminum base material 88 when theplatinum layer 90 is plated. Thenickel layer 96 helps settle theplatinum layer 90 onto thetitanium layer 92. - According to this embodiment, the
platinum layer 90 is formed by electrolytic plating to a thickness of 0.01 μm. Theplatinum layer 90 may be formed by non-electrolytic plating. Thetitanium dioxide layer 92 is formed by vapor deposition to a thickness of 5 to 15 μm. Thetitanium dioxide layer 92 is formed when deposited titanium (Ti) changes into titanium dioxide (TiO2) as time passes. Namely, a product to be marketed includes thetitanium dioxide layer 92 altered from a deposited titanium layer. The nickel layers 94 and 96 are each formed by coating to a thickness of 0.5 μm. - The
platinum layer 90, titanium dioxide (TiO2)layer 92, and nickel (Ni) layers 94 and 96 may have optional thicknesses if their respective functions are secured. - The functions of the
platinum layer 90 and titanium dioxide (TiO2)layer 92 and the magnetic action of themagnet plate 71 effectively cause oxidization and reduction to permanently process hair without losing moisture of the hair. - Treating hair as shown in
FIG. 10( a) with thecorrector 11 having the correctingsurface 87A and thecorrector 13 having the correctingsurface 87B can regulate the surfaces of hair H and gloss the hair due to the operation of the mirror surface of the correctingsurface 87A. In addition, the hair enters into the recesses of the correctingsurface 87B of thecorrector 13, to increase contact points or contact areas of the hair. The increased contact points or contact areas disperse force “f” of thecorrector 13 acting on the hair. In addition, the increased contact points or contact areas disperse heat transmitted from the correctingsurface 87B to the hair. - On the other hand, the comparative example of
FIG. 10( b) includescorrectors surface 87A whose aluminum (Al) base material is mirror-finished on which a platinum (Pt)layer 90 of about 0.01 μm is plated. - When
such correctors correctors mirror correcting surfaces 87A of thecorrectors - On the other hand, according to the embodiment of the present invention, the correcting
surface 87B disperses heat and force acting on each hair, to suppress a dry finished state and curls. In addition, the correctingsurface 87A of mirror state can gloss the hair. - The
casing 77 is hollow and is formed along aflat back 89 of thethermal plate 67. Each end of thecasing 77 is open at each end of the corrector 11 (13). From one end of thecasing 77, it is possible to insert thefirst spring 73,ceramic heater 69, andmagnet plate 71 into thecasing 77. Thecasing 77 has arear wall 91 having anopening 93. Upper and lower edges of therear wall 91 haverecesses 95 to support and slide thesecond spring 75. - As shown in
FIG. 11 , thefirst spring 73 is made of a plate spring. The center of thefirst spring 73 has acurved portion 97. One end of thefirst spring 73 has a foldedportion 99 and the other end thereof has abent portion 101. The foldedportion 99 andbent portion 101 support themagnet plate 71. - As shown in
FIG. 12 , thesecond spring 75 is made of a plate spring. The ends 75 a and 75 b of thesecond spring 75 are formed on each side of a flatmiddle portion 103. Each widthwise edge of themiddle portion 103 forms ahook portion 105. Each edge of theends engaging part 107 to engage with a projection of thedivisional part 43 a as mentioned above. - For assembling, the
magnet plate 71 is supported with the foldedportion 99 andbent portion 101 of thefirst spring 73 in advance as shown inFIG. 10 . Theceramic heater 69 is arranged on themagnet plate 71. Thefirst spring 73,magnet plate 71, andceramic heater 69 are assembled into an assembly, which is inserted into thecasing 77. At this time, the assembly can easily be inserted through an end opening of thecasing 77. - Once the assembly is received in the
casing 77, thecurved portion 97 of thefirst spring 73 bends to produce a repulsive force that tightly pushes theceramic heater 69 against the back 89 of thethermal plate 67. This results in fixing the assembly of thefirst spring 73,magnet plate 71, andceramic heater 69 within thecasing 77, thereby making the assembling work easier. - Next, the
hook portions 105 of thesecond spring 75 are engaged with therecesses 95 of therear wall 91 of the corrector 11 (13), to attach themiddle portion 103 of thesecond spring 75 to therear wall 91 of the corrector 11 (13). At this time, thesecond spring 75 is slid from an end of therear wall 91. Alternatively, themiddle portion 103 of thesecond spring 75 is placed on therear wall 91 and is pressed to therear wall 91. When thesecond spring 75 is attached to therear wall 91, themiddle portion 103 is attracted by themagnet plate 71 and thesecond spring 75 is thereby positioned with respect to therear wall 91. In this way, thesecond spring 75 can freely be moved relative to therear wall 91 and can be positioned at a moved location with the magnetic force mentioned above. In this way, the positioning of thesecond spring 75 can very easily be carried out. - Thereafter, the corrector 11 (13) with the assembly of the
second spring 75 is placed in thecorrector support hole 65 of thedivisional part 45 a (45 b), the otherdivisional part 43 a (43 b) is attached thereto, and predetermined locations are fastened to complete the fabrication. - Operation of the
hair iron 1 to straighten curly hair or artificial permanent waves of hair will be explained. - When using the
hair iron 1, a first water solution mainly containing a mercapto compound (reduction agent) such as thioglycol acid and cysteine is prepared. To the first water solution, a basic material such as ammonia, monoethanolamine, and triethanolamine is added to adjust pH to 6 to 10. This liquid is applied to hair. The liquid reduces disulfide bonds of cystine contained in keratin protein of the hair and cuts the same as mercapto groups. Thereafter, the hair is washed with water and is successively dried with a drier. Thehair iron 1 is adjusted to a temperature of 160 to 180° C. and is applied to the hair to straighten the hair. - More precisely, the
grips clamp arms pressing points thermal plates 67 of thecorrectors clamp arms thermal plates 67 heated with theceramic heaters 69. - At this time, the correcting
surface 87B disperses heat and force acting on the hair, to suppress dryness and curl of finished hair and the mirror-state correcting surface 87A glosses the hair. The correctingsurface 87A must be put on the surface side of the hair, to gloss the surface of the hair. To make the correctingsurfaces clamp arms - The platinum layers 90 of the
correctors thermal plates 67 from drying. At this time, themagnet plates 71 achieve magnetic action to pulverize ambient water clusters so that the hair may easily absorb the water. Namely, the magnet plates pulverize the ambient water clusters collected by the platinum layers 90 so that the hair may easily absorb water and increase water content. - Each
platinum layer 90 achieves a catalytic function to atomize harmful substances and organic compounds and eachtitanium dioxide layer 92 carries out a photocatalytic function to convert the substances atomized by theplatinum layer 90 into harmless water and carbon dioxide. The photocatalytic function of the titanium dioxide layers 92 also generates negative ions to neutralize the harmful substances. - At the same time, each
magnet plate 71 performs a magnetic action to generate negative ions. In addition, themagnet plates 71 create low-frequency oscillations of electromagnetic waves and electromagnetic fields around the same to periodically vibrate water in the hair, energize the water, and activate the water. - In this way, each
platinum layer 90 achieves the water sustaining effect on the hair, so that thethermal plates 67 may surely correct curls of the hair and secure a gloss of the hair. - The platinum layers 90 and titanium dioxide layers 92 provide a synergistic effect (catalytic effect) to treat hair and promote health of the hair.
- The synergistic effect of the platinum layers 90 and titanium dioxide layers 92 decomposes harmful substances into harmless substances to improve a hair treating environment.
- The platinum layers 90, titanium dioxide layers 92, and
magnet plates 71 provide synergistic effects of minimizing damages on hair due to heat and pressure produced by thehair iron 1 and atomizing, decomposing, and removing harmful substances and organic compounds, to maintain best hair treating conditions. - When the
hair iron 1 is used on hair after carrying out a one-liquid treatment of the permanent liquid in a permanent process, the particle decomposing function of the platinum layers 90 atomizes harmful substances and organic compounds. At the same time, the titanium dioxide layers 92 achieve the oxidation-reduction catalytic action and ion effect. These functions and effects deodorize the permanent liquid and decompose harmful substances. - Generally, an odor of ammonia remains on hair after a two-liquid treatment in the permanent process. The platinum layers 90 and titanium dioxide layers 92 can remove the smell of ammonia remaining after the permanent process, to maintain a proper hair treating environment.
- The hair is moved at a given speed between the
magnet plates 71 whose S- or N-poles are facing each other. Themagnet plates 71 generate reduction energy due to the Fleming's right-hand rule. This energy is generated by the S-pole of eachmagnet plate 71 where electrons turn rightward, to promote a reduction action of the one-liquid. The energy also works to close cuticles on the surface of each hair. Closing the cuticles prevents ultraviolet rays from entering and damaging the hair. - The reduction energy makes water clusters in the first liquid smaller. The small water clusters help the first liquid permeating into hair. The reduction energy also promotes reduction of the first liquid, to shorten a treatment time to thereby prevent the hair from being damaged.
- Thereafter, the two-liquid, i.e., a water solution of oxidant such as sodium bromate and hydrogen peroxide is applied to the hair, to oxidize mercapto groups and produce new disulfide bonds on the hair. This results in settling the straightened state of the hair.
- In the case of the
magnet plates 71 arranged so that their S-poles face each other, themagnet plates 71 repel each other when thecorrectors clamp arms magnet plates 71 become parallel to each other. This results in aligning thecorrectors surfaces 87 parallel to each other. When theclamp arms surfaces 87 of thecorrectors - If the
magnet plates 71 are arranged so that their S- and N-poles face each other, themagnet plates 71 quickly attract each other. At this time, thesecond springs 75 bend to make themagnet plates 71 parallel to each other. Namely, when the correctingsurfaces 87 of thecorrectors surfaces 87 are already in parallel with each other. - In this way, when the
correctors clamp arms magnet plates 71 andsecond springs 75 cooperate to automatically make thecorrectors - When the
correctors correctors - When the
magnet plates 71 are arranged with their S- and N-poles facing each other, thecorrectors clamp arms second springs 75 absorb a shock, to properly treat hair. - Each
magnet plate 71 is pressed toward thethermal plate 67 by thefirst spring 73, so that themagnet plate 71 is stably supported on the corrector 11 (13). Themagnet plates 71 andfirst springs 73 cooperate to surely align thecorrectors - Between the back 89 of the
thermal plate 67 and themagnet plate 71 in thecasing 77, theceramic heater 69 is arranged to conduct heat through the back 89 to thethermal plate 67. Theceramic heater 69 is tightly attached to theback 89 of thethermal plate 67 by the pressing force of thefirst spring 71, so that theceramic heater 69 can efficiently conduct heat to thethermal plate 67. - The present invention is not limited to the above-mentioned embodiment.
- For example, the
body 5 may have an optional shape. The temperature controller and temperature display can be arranged at optional locations on thebody 5. - The
magnet plate 71 may be arranged on only one of thecorrectors correctors magnet plate 71. It is possible to omit thefirst spring 73. One of the correctingsurfaces - Only one of the correcting
surfaces 87 of thecorrectors platinum layer 90, titanium dioxide (TiO2)layer 92, and nickel (Ni) layers 94 and 96. - It is possible to omit the titanium dioxide (TiO2)
layer 92 and/or the nickel (Ni) layers 94 and 96.
