Description

[Detailed description of the invention] [Industrial field of application] This invention is a hair iron that curls hair by heating and deforming the hair. Targets devices that can form multiple waves.

[Conventional technology]

Conventional hair irons of this type include, for example, Utility Model No. 61789, published in 1983, or
Publication No. 106102 etc. have been proposed earlier. In such a hair iron, as shown in FIG. 7, continuous wave-shaped hair nipping surfaces 19, 20 are formed on the opposing surfaces of a pair of facing templates 17, 18, and the hair is held between the two hair nipping surfaces 19, 20. By clamping and fixing the hair along the hair clamping surfaces 19 and 20 and heating the hair for a certain period of time while maintaining this state, waves having the same shape as the hair clamping surfaces 19 and 20 can be formed on the hair. the hair pinching surface 19;
20 are formed to have the same cross-sectional shape so as to be in close contact with each other in the occlusal state, and the occlusal interval g is set to be the same in the width direction. 5a is a heater.

[Problem that the invention attempts to solve]

In the above-mentioned conventional hair iron, when hair is clamped and fixed, all the protrusions 28 and 29 on the hair clamping surfaces 19 and 20 come into contact with the hair at the same time, and simultaneously clamp and hold the hair in the width direction. . At this time, as the hair nipping surfaces 19, 20 approach each other, the hair is gradually drawn toward the center in the width direction of the hair nipping surfaces 19, 20, but the minimum distance E between the hair nipping surfaces 19, 20
When the thickness of the hair becomes smaller than the sandwiching thickness of the hair, the hair is immovably sandwiched and fixed between the adjacent protrusions 28 and 29 in opposing positions. In other words, the hair is restrained so as not to be able to move before the hair can fit along both the hair pinching surfaces 19 and 20 without any gaps. Therefore, near the center of the hair pinching surfaces 19 and 20, the hair is
At steps 8 and 29, it is strongly pressed and forcibly bent.
At this time, the hair is heated and deformed under a strong tensile force, and is easily damaged by curling, and is also prone to breakage and split ends.

[Purpose of invention]

The purpose of this invention is to obtain a hair iron that can eliminate the above-mentioned hair damage by improving the structure of the hair clipping surface.

[Means for solving problems]

In this invention, when the hair is clipped, the hair is held at the hair clipping surface 19,
The hair is sandwiched and held in order in the width direction of the hair clipping surfaces 19 and 20, so that the hair can be easily made to follow the cross-sectional shape of the hair clipping surfaces 19 and 20. For this purpose, the protrusions 2 that are adjacent to each other in opposing positions on the pair of hair-pinching surfaces 19 and 20
The minimum occlusal interval G between 8 and 29 is the hair pinching surface 1.
9 and 20 are characterized in that they gradually increase toward the outside in the width direction.

Specifically, for example, as shown in FIG.
By arranging the protrusions 28 and 29 so as to recede toward the back of the hair-pinching surfaces 19 and 20 as they move outward in the width direction from 9 as a reference, the occlusal interval G becomes outward in the width direction. The amount will be gradually increased towards the end. The arrangement positions of the convex portions 28 and 29 are preferably changed on both of the opposing hair-pinching surfaces 19 and 20, but in some cases, the change may be made on only one of them. In addition, in FIG. 1, the hair clipping surface 19,
Although the case where the minimum occlusal interval G is the minimum at the center in the width direction of 20 is shown, the part where the minimum occlusal interval G is the minimum can be anywhere between the center in the width direction and one side edge in the width direction. You can.

[Effect]

As described above, when the minimum interocclusal interval G of the hair-pinching surfaces 19, 20 is gradually increased from the center or one side edge of the surfaces 19, 20 toward the outside in the width direction, the hair is separated from the portion where the minimum interocclusal interval G is the narrowest. It is first held between the
As the minimum occlusal interval G increases from this point on, the pieces are pinched and fixed one after another. Therefore, the hair has each protrusion 28,
29, it is sufficiently pressed against the other side's hair pinching surfaces 19, 20, and can easily follow both hair pinching surfaces 19, 20, and it is possible to prevent tensile force from acting on the hair in this pinch holding state. .

[Effect of idea]

As described above, in the present invention, the opposing hair clipping surfaces 1
The minimum occlusal interval G of 9 and 20 is gradually increased outward in the width direction so that the hair is successively pinched and fixed in the width direction during use, so that the hair pinching surface 19 can be fixed without applying an unreasonable tensile force. , 20 and can be fixed by sandwiching the hair. This allows you to curl your hair without damaging it.
It is possible to prevent future hair breakage and split ends, and to maintain the hair in a healthy state even if the wave shape is repeatedly changed or erased.

1 to 4 show an embodiment in which this invention is applied to a hair iron attachment for a hair dryer.

In Fig. 2, 1 is a hair dryer body and 2 is a hair iron body. Hair is held between the hair iron body 2 and heated for a certain period of time with hot air supplied from the hair dryer body 1 to form waves. do.

The hair dryer 1, which is a hot air supply means, has a heat generating part 5 by a heater, a motor 6, and an axial fan 7 disposed in order from the front inside a main body case 4 which is elongated in the longitudinal direction. A hot air outlet 8 covered by an outlet grille 8a is provided on the front lower surface of the main body case 4, and an inlet 9 is provided at the rear.A fan 7 is rotated by a motor 6 to suck air from the inlet 9 and generate heat. After heating by section 5, air outlet 8
It blows hotter air downward. Flanges 10 are fitted to the left and right opening edges of the air outlet 8, into which the hair iron main body 2 is fitted so as to be freely inserted and removed.
10 is formed in the front-back direction.

The hair iron main body 2 includes a pair of upper and lower battledore-shaped hair clipping plates 3A and 3B arranged so as to be able to swing toward each other. The hair clipping plates 3A and 3B have band-like grip portions 12 and 13, and hair clipping portions 14 and 15 having a dish-shaped cross section and integrally formed at the tips of the grip portions 12 and 13, respectively. The rear ends of 13 are connected to the support shaft 16
The hair clipping plates 3A and 3B are pivoted so as to be swingable, and a torsion coil spring 16a urges the hair clipping plates 3A and 3B into an open position.
Templates 17 and 18 made of punching metal are fixed to the opposing surfaces of the hair clipping portion, respectively.
18 is bent into a corrugated cross-section to form hair-pinching surfaces 19 and 20 that interlock with each other. template 17,
A large number of holes 18 are used as ventilation holes 21 on the template 17 side and as exhaust holes 22 on the template 18 side.

A hot air supply port 23 is provided on the back side of the upper hair clipping section 14.
is opened, and the hot air supply port 23 is connected to the air blow hole 2.
1 is connected. On the other hand, the lower hair clipping part 15
A large number of blow-off holes 24 are formed in the back wall surface of the blow-off hole 24, and the blow-off holes 24 are communicated with the exhaust hole 22.

As shown in FIG. 4, the hot air supply port 23 opened on the back side of the upper hair clipping part 14 is formed to match the opening size and shape of the hot air outlet 8 of the hair dryer 1, and The hot air supply port 23
Planar view U surrounding only the left, right, lateral, and front three sides of
A letter-shaped boss 25 is provided protrudingly. This boss 25
is inserted into the flanges 10, 10 from the front, slid backward, and fixed at a position where the hot air outlet 8 and the hot air supply port 23 match. Then,
As shown in FIG. 2, the grip part 1 of the upper hair clipping plate 2
2 is attached to the lower surface side of the main body case 4.

The most distinctive feature of this invention is that, in the above-mentioned hair iron, the occlusal interval between the protrusions 28 and 29 adjacent to each other at opposing positions of the hair clipping surfaces 19 and 20 is set as follows.

In FIG. 1, the distance between adjacent convex portions 28 and 29 at the center in the width direction of the hair-pinching surfaces 19 and 20, that is, the minimum occlusal distance G at the center, is set to be the minimum value, and as it goes outward from this, The minimum interocclusal interval G is set to gradually increase. Specifically, the imaginary lines P and Q connecting the tips of the convex portions 28 and 29 on each hair-pinching surface 19 and 20 are set as projecting arcs, and the minimum occlusal interval G of both hair-pinching surfaces 19 and 20 is set in order. change.

In the hair iron configured as described above, the main body case 4 and the lower hair clipping plate 3B are held, and hair is sandwiched and fixed between the hair clipping surfaces 19 and 20. At this time, adjacent convex portions 28 on each hair pinching surface 19, 20,
Since the minimum occlusal interval G of No. 29 gradually increases from the center toward the outside in the width direction, the hair is first held in place at the center, and then held in order toward the outside. Therefore, the hair can be made to fit along the upper and lower hair nipping surfaces 19 and 20 without strain.

The hot air supplied from the hot air outlet 8 is transferred to the template 17.
The air is blown onto the hair through the air outlet 21 of
It is released to the outside via 4. By allowing the hot air to pass through both the hair nipping surfaces 19 and 20 in this way, the hair is constantly exposed to new hot air and can be heated efficiently. When the templates 17 and 18 are separated after being heated for a certain period of time, waves having the same shape as the hair pinching surfaces 19 and 20 are formed on the hair.

[Another example]

Only one of the hair-pinching surfaces 19 and 20 in the above embodiment may be formed into a projecting arc shape.
In other words, the imaginary lines P and Q connecting the tips of either the convex portions 28 group or the convex portions 29 groups may be formed as projecting arcs, and the other may be arranged so as to be flat.

Alternatively, as shown in FIG. 5, the minimum interlocking interval G may be set at one side edge of the hair-pinching surfaces 19, 20, and the interval G may be gradually increased from there toward the other side edge. In this case, the imaginary lines P and Q connecting the respective protruding ends of the convex portions 28 and 29 may be straight lines as shown.

FIG. 6 shows that the minimum occlusal interval G is achieved by sequentially changing the cross-sectional shape of the convex portions 28 and 29, that is, the apex angle is small in the center and increases as it goes outward. It is a gradual increase. In this case, both the group of convex portions 28 and the group of convex portions 29 may be arranged on the same flat plane.

In addition to the above, the present invention is also intended to be applied to a method in which the templates 17 and 18 are directly heated with the heater 5a, as explained in the conventional example in FIG. It is not limited to the hot air heating method. Furthermore, in the above embodiments, a case has been described in which the present invention is applied to an attachment for a hair dryer, but it is needless to say that this is not necessary and a machine exclusively for hair irons may be used. Furthermore, the templates 17 and 18 can also be formed of metal nets.
