The present invention relates to a hair iron for providing a straight permanent or permanent wave to the hair.

Conventional hair irons include, for example, those shown in Figs. 10A and 10B (see Japanese Patent Laid-Open No. 2001-137038). FIG. 10A is an overall view and FIG. 10B is a sectional view of principal parts.

10A and 10B, in the conventional hair iron 201, a power cord 205 is connected to an iron body 203, and a temperature control device 207 is connected to an intermediate part of the power cord 205. The power plug 209 is installed at the end.

The iron body 203 is provided with a pair of sandwiching arms 211 and 213 made of resin. In the sandwiching arms 211 and 213, the proximal ends 215 and 217 are rotatably coupled to each other, and the correcting bodies 223 and 225 are disposed opposite to the distal ends 219 and 221.

An intermediate portion of the clamping arms 211 and 213 is configured as the grip portions 224 and 226, and an inverted portion located behind the correctors 223 and 225 on the front end side of the grip portions 224 and 226. (227) 229 are comprised.

Then, the power plug 209 is plugged into an outlet, and the temperature correcting elements 223 and 225 are heated by the temperature control device 207 to hold the holding portions 224 and 226, and the thumbs to the power point portions 227 and 229. When the force is applied to the index finger, the correcting members 223 and 225 on the tip sides 219 and 221 perform the pinching operation. By holding the hair by this clamping operation, the hair is slid while being held, and the hair can be clamped by applying a warming action due to the heat generated by the correcting members 223 and 225.

Therefore, by using such a hair iron, it is possible to straighten innate curly hair or fix an artificial permanent wave.

By the way, since the iron main body 203 of the said hair iron 201 carries out work by holding for a predetermined time, it is as lightweight as possible. That is, as mentioned above, the clamping arms 211 and 213 are resin-made and the inside is hollow. Therefore, the iron main body 203 can continuously work for a predetermined time and work to avoid the minute curls.                         

However, due to the heat generated by the correcting bodies 223 and 225, in particular, the hardness of the front end sides 219 and 221 where the correcting bodies 223 and 225 are present decreases with the temperature rise, and thus the stationary portions 227 and 229 When the force is applied to clamp the hair, the tip ends 219 and 221 may be easily deformed. For this reason, a force does not transfer smoothly from the inflection point 227, 229 to the front end side 219, 221, but it interferes with the pinching of the hair by the straighteners 123, 125, and the curled hair There was a problem that things could not be performed smoothly.

In response to such a problem, by easily increasing the heat capacity by increasing the thickness of the sandwiching arms 211 and 213, easy deformation due to heat on the tip ends 219 and 221 can be suppressed to some extent. However, increasing the thickness of the sandwiching arms 211 and 213 increases the overall size and increases the weight. Therefore, the holding of the iron body 203 and the fine curling hair by the free operation are continued for a certain time. It may be accompanied by difficulty.

Therefore, even when the temperature rises, it is a problem that both the smooth transfer of the force from the power point portions 227 and 229 to the tip ends 219 and 221 and the weight reduction of the entire iron body 203 are difficult.

An object of this invention is to provide the hair iron which can aim at both the smooth transfer of a force and the weight reduction of the whole iron body irrespective of temperature rise.

The core member 83 is provided with ball fastening portions 89 and 91 at both ends of the long plate-shaped base portion 87. The ball fastening portions 89 and 91 are fastened together with the fitting fastening of the divided portions 43a and 45a and the divided portions 43b and 45b. The ball fastening portion 89 is formed with a hole 89a for inserting a screw, which is a fastener, and a hole 91a is formed in the ball fastening portion 91 in the same manner. A temporary stop 93 is provided at an end thereof in succession to the ball fastening portion 91. The temporary stop 93 is provided at one end in the long side direction of the core material 83 and is for coupling to the divided portion 45a in advance. The temporary stop 93 is provided with a positioning hole 93a into which the positioning pin 94 protruding toward the divided portion 45a is fitted. Further, the temporary stop 93 is provided with a hole 93b for inserting a bis which is a temporary stop fastener.

A vertical wall portion 95 is provided along one edge of the base portion 87. The vertical wall portion 95 serves as a stopper portion of the corrector 11. The other vertical wall part 97 is provided along the other edge of the said base part 87, the ball fastening part 91, and the other edge of the temporary stop part 93. As shown in FIG.

First and second fastening wall portions 99 and 101 are additionally protruded from the vertical wall portion 97. These first and second fastening walls 99, 101 are fastened and fixed to the divided portion 43a. Further, the first fastening wall 99 is located between both ends 75a and 75b of the second spring 75. That is, the 1st fastening wall part 99 comprises the accommodating part which can support the said 2nd spring 75 facing the back part of the 2nd spring 75 which is a press means.

9A to 9D of the first fastening wall portion 99 in the left and right directions, both ends of the long side direction of the first fastening wall portion 99 in the state of FIG. 75a, 75b), or it is set in the state which opposes with a slight gap.

The core material 83 is disposed in the tip side 29 as shown in Figs. 6 and 7, the base portion 87 is disposed on the bottom wall surface 63, and the vertical wall portion 95 forms the vertical wall surface 61. The vertical wall portion 97 and the first and second fastening portions 99 are disposed along the vertical wall surface 59. In this state, the first and second fastening wall portions 99 and 101 are fastened and fixed to the divided portion 43a side by the bis 103 as fasteners.

The ball fastening portions 89 and 91 are fastened to each other by the screws 48 and 49 together with the fastening of the divided portions 43a and 45a. Moreover, in the temporary stop part 93, the positioning pin 94 of the division part 45a side is fitted in the positioning hole 93a, and it is provided to the division part 45a side by a screw in the hole 93b. Are combined.

That is, when attaching the core material 83, the core material 83 is arrange | positioned at the division part 45a side before fastening and combining the division parts 43a and 45a, and the positioning pin (a) is located in the positioning hole 93a. 94 is inserted, the screw is passed through the hole 93b and fastened to the divided portion 45a side. As a result, the core material 83 is temporarily stopped at the divided portion 45a side.

Next, the corrector 11 is mounted, and the screws 48, 49, and 51 are fastened and fixed by aligning the divided portion 43a with the divided portion 45a. As a result, the divided portions 43a and 45a are fastened to each other, and the ball fastening portions 89 and 91 of the core material 83 are fastened together by the bis 48 and 49 as described above. Therefore, the core material 83 can be mounted very easily.

In the mounting of the core 83, even if the hole 89a of the ball fastening portion 89 is slightly shifted from the screw hole of the divided portions 43a and 45a, the temporary stop 93 is the core 83. Since the core member 83 is easily bent using the temporary stop 93 as a supporting point, the shim can be easily aligned by inserting a bis. The fastening by the screw 48 can be performed very easily.

Next, the case where the curling hair is straightened or the artificial permanent wave is fixed using the hair iron 1 will be described. It goes without saying that the permanent wave can also be performed by the hair iron 1.

First, in the use of the hair iron (1), firstly, ammonia, monoethanolamine, triethanolamine, or the like is contained in an aqueous solution mainly containing a first agent, ie, a mercapto compound (reducing agent) such as thioglycolic acid or cysteine, in the hair. The basic material of was added, and the liquid agent adjusted to pH 6-10 is apply | coated. By this application, the disulfide bond of cysteine contained in the keratin protein in the hair is reduced and cleaved as a mercapto group. After that, the hair is washed and dried with a dryer or the like, and then heated to 140 to 180 ° C. This hair is straightened by the iron (1).

Specifically, the gripping portions 21 and 23 of the clamping arms 7 and 9 are gripped, and a force such as a thumb and forefinger is applied to the emphasis portions 25 and 27 to provide the corrective bodies 11 and 13. The hair is sandwiched between the hot plates (67). Thereafter, the state can be maintained and the pinching arms 7 and 9 can be slid to the tip of the hair. As a result, the hair sandwiched between the hot plates 67 heated by the ceramic heater 69 is stretched while being heated.

At this time, since the hair moves at a predetermined speed between the magnet plates 71 in which the S poles are replaced, reducing energy is generated by the right hand rule of flaming. This energy is generated at the S pole of the magnet plate 71 in which the electrons of the magnetic pole turn right, thereby promoting the reducing action of the first liquid. Moreover, it also functions to close the cuticle forming the surface layer of the hair. When the cuticle is closed, it can block ultraviolet rays from entering the hair, preventing the hair from being damaged by the ultraviolet rays.

Moreover, this reduction energy reduces the cluster of the water of a 1st liquid. As this cluster becomes smaller, the permeability of the first liquid to the hair is increased. Therefore, the reducing action of the first liquid is further promoted. As a result, the procedure time accompanying the fear of hair damage can be shortened, and hair damage can also be suppressed.

After that, a second liquid comprising an aqueous solution of an oxidizing agent such as sodium succinate or hydrogen peroxide is applied to the hair. As a result, the mercapto group is oxidized to generate new disulfide bonds in the hair, thereby fixing the straight hair state. .

In such hair insertion straightening, the heat of the ceramic heater 69 is also conducted to the tip ends 29 and 31 of the pinching arms 7 and 9, so that the tip sides 29 and 31 of the pinching arms 7 and 9 are transferred. The hardness of the resin decreases and the deformation becomes easy.                     

Therefore, when there are no cores 83 and 85, the tip side 29 is formed by the reaction force applied to the tip sides 29 and 31 of the clamping arms 7 and 9 during the hair insertion operation between the hot plates 67. , 31) is easily deformed, and there is a fear that the pinching of the hair by the hot plate 67 may not be performed evenly. On the other hand, by providing the core materials 83 and 85, this problem can be improved.

In other words, the cores 83 and 85 are embedded from the tip side 29 and 31 at least over the grip portions 21 and 23, and the grip portion 21 and 23 side is compared with the tip side 29 and 31. It maintains the temperature state so that it can be grasped | broken by, and the core materials 83 and 85 can be firmly supported by the holding part 21 and 23 side.

And the ball fastening part 91 side of such firmly supported core material 83 and 85 is located in the inversion part 25 and 27 of the holding part 21 and 23, and the core material (from the inversion part 25 and 27) 83, 85) can accurately transmit force.

By correct force transmission to the cores 83 and 85, the correcting bodies 11 and 13 are supported by the cores 83 and 85, and easy deformation of the tip sides 29 and 31 can be prevented. . Therefore, the hot plates 67 can be precisely opposed to each other to pinch the hair, so that the procedure can be performed more accurately.

In addition, in this embodiment, since the correctors 11 and 13 are pressed by the second spring portion 75 which is the press means, the clamping states 11 and 13 are elastically adjusted to each other. The above procedure can be performed more accurately.

The movement of the correctors 11 and 13 in the projecting direction can be regulated by the vertical wall portion 95 as the stopper portion, the shape of the correctors 11 and 13 can be suppressed, and the second spring portion ( The accurate retraction operation of the correcting members 11 and 13 by the pressing operation of 75 can be maintained for a long time, and the precise clamping state of the hot plate 67 can be maintained accurately.

The second fastening wall portion 99 as the receiving portion can receive the second spring portion 75 by bringing both ends 75a and 75b into contact with the rear portion of the second spring 75 as the pressing means. Therefore, the reaction force of the second spring portion 75 can be accurately acted on the hot plate 67.

Therefore, the holding | maintenance state of the clamping body 11 and 13 mutually by the 2nd spring 75 can be hold | maintained correctly, regardless of the heat rise of the front end side 29 and 31. As shown in FIG. In addition, since the first fastening wall portion 99 serving as the housing portion is partially provided in the cores 83 and 85, the clamping arms 7 and 9 are held by the grip portion (as shown in, for example, the plane of FIG. 8). Even if it is a form tapered to the front end side 29 and 31 side from 21 and 23, it can form without being influenced by this shape. The base portion 87 of the cores 83 and 85 can be disposed on the flat bottom wall surface 63 on the tip sides 29 and 31, so that the base portion 87 can be straight and straight to the grip portions 21 and 23 side. Can be.

In addition, this invention is not limited to the said Example. For example, one or both of the correcting bodies 11 and 13 may be fixed so as not to move with respect to the tip sides 29 and 31. The magnet plate 71 and the first spring 73 can also be omitted. The vertical wall portion 95, the first fastening wall portion 99, and the like of the core materials 83 and 85 may be omitted.

The cores 83 and 85 may be integrally provided on any one of the divided portions 45a and 45b or the divided portions 43a and 43b by two-color molding or the like.

In the invention of claim 1, when the gripping portion of the middle portion of the gripping arm is gripped and operated, the proximal end rotates with each other, and the distal end side performs the gripping operation. By this clamping operation, the hair can be clamped by the straighteners which are arranged on the distal end side of the clamping arm.

And a core material is embedded so that it may follow a long side direction from the front end side of the said clamping arm to at least the holding part, The said core material will maintain hardness to a temperature higher than the said clamping arm, and the tip of the clamping arm at the time of heat_extraction of the said correct | amendment body Easy deformation due to heat on the side can be regulated. Accordingly, the gripping portion of the gripping arm can be gripped to smoothly transfer the force from the distal end side of the gripping arm to the straightener, so that the hair can be clamped reliably.

Therefore, even if the narrowing arm is thinned and the heat capacity is reduced, the pinching of the hair can be reliably carried out, and the weight of the pinching arm can be reliably reduced. It becomes easy to carry out.

In the invention of claim 2, in addition to the effect of the invention of claim 1, the clamping arm is movable and supported such that one side of the corrective body is retractable with respect to the other side, and the clamping body is pressed against the clamping arm to sandwich the corrected body with each other. Since the pressurizing means which adjusts a state elastically is provided, the hair can be reliably clamped by the straight body.

Moreover, since the receiving member is provided with the core member facing the rear portion of the pressing means, the holding portion capable of supporting the pressing means can receive the clamping reaction force by the correcting body by the receiving portion through the pressing means. The hair can be clamped more reliably.

Since the said accommodating part is provided, the shape is hard to be influenced by the clamping arm side curved shape etc., and the accommodating part can be easily arrange | positioned at the back part of a press means.
