ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a hair iron for straight or wave-perming hairs, especially to a hair iron for expressing a predetermined desired image at hair itself, in which the hair iron is used at barbor shops, beauty salons and homes.
2. Description of the Related Arts
A hair iron for perming hair into straight or wave hairdos of the type including a pair of arms or fingers pivotally joined to each other to make an opening and closing movement is known in the art. An example of that type of hair iron, as shown in
FIG. 1
, has a pair of arms joined by a pivot
1
at their one ends to enable closing and opening movements according to appliance and release of the gripping force to the arms. The first and second arms
2
and
3
are provided with forming plates
5
and
6
, respectively. Opposing surfaces of the forming plates have planar or corrugated surfaces which match each other. At least one of the forming plates
5
and
6
is connected to a heater
4
to heat the plates electrically. A desired hairstyle is accomplished by pulling down little by little the hair iron pressing the arms after holding hair between the forming plates
5
and
6
. At this time, what state of the hair is attained is dependent on how the hair comes into contact with the forming plates
5
and
6
between which the hair is grasped, because hair, when heated, will conform to the shape of the plates on which the hair is held for a certain period of time, as is well-known.
The conventional hair irons of the type as examplarily illustrated in the above are able to make hair curled, waved, or straightened, but there have been no arts or hair irons for providing decorative figures of a character, pattern, or design to the hair itself in a region-wise manner. Therefore, hairdressing accessories have been often employed after treating the hair by using the conventional hair irons. Such hair dressing accessories are separately attached to the hair, not expressed on the very hair itself as decorative designs.
In addition, with the conventional hair irons in which the forming plates
5
and
6
approach and leave with each other by the opening and closing movement of the arms around a shaft such as a pivot pin so as to hold therebetween and treat the hair, contact about the end portions of the forming plates
5
and
6
takes place without the even surface-to-surface contact of the forming plates
5
and
6
over the entire opposed surfaces thereof so that the large portions of surfaces of the forming plates remain without contact with each other. Uneven contact between the forming plates leads to the poor gripping of the hair so as to result in a bad hairdressing state.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a hair iron having an image marker capable of expressing an image of a character, pattern, or predetermined design by forming an embossed-intaglioed or concave-convex portion on the very hair itself at a desired portion in the hair.
It is another object of the present invention to provide a hair iron having support protrusions which cause a seesaw movement of hair treatment members to allow the hair treatment members provided to each arm to be in a close and even surface-to-surface contact when the arms are closed so that the gripping and treatment of hair is attained effectively.
It is still another object of the present invention to provide a hair iron able to apply various types of hair styles by employing twined hair treatment members for holding and treating the hair which are attachable and releasable to a pair of arms or another pair of hair treatment members installed in the corresponding arms, respectively.
According to the present invention, a hair iron comprises: a gripping portion; twined hair treatment members designed to be heated up for pressing and treating hair therebetween; and an image marker of a concave and convex type provided on opposing surfaces of said hair treatment members for imparting an image with the hair by holding and pressing the hair between said hair treatment members when said hair treatment members approach each other.
