HAIR IRON HAVING BUFFER MEMBER
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a hair iron having a buffer member,
particularly to a
hair iron having a buffer member, which is located in between two opposing
steel plates to
help hair between the steel plates to be straightened smoothly and prevent
thermal
deformation of hair.
2. Description of the Related Art
A hair iron is an apparatus used to straighten or roll hair at home or beauty
salons.
FIG. 1 is a drawing showing the conventional hair iron. It is manufactured by
inserting
thermal wire heaters 13b into two opposing steel plates 12b. When the steel
plates 12b are
heated by the thermal wire heaters, you can straighten or roll your hair by
applying pressure
from outside of the external case 11 a. Such a conventional hair iron is
driven by a power
supply. Descriptions on the power supply, including electric wires and the
temperature
controller 70, will be omitted here.
A first pressing member 1 and a second pressing member 2 are joined by a hinge
5.
To the first pressing member I is fixed a spacing stick 60. The spacing stick
60 has a
projecting part 61 at the end. The second pressing member 2 has a spacing
member 62,
which allows the spacing stick 60 to move up and down. Thus, the spacing
between the first
pressing member and the second pressing member can be adjusted by pressing
with fingers.
At the bottom of the spacing member 62 is mounted a spring 63.
In the conventional hair roller, the steel plates 12b touch with each other,
so that it
la

does not fix hair smoothly. Also, hair may be damaged because of the heated
steel
plates.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a hair iron having a
buffer member,
which is located in between two opposing steel plates to help hair between the
steel plates to
be straightened smoothly and prevent thermal deformation of hair.
To attain the object, the present invention provides a hair iron comprising a
first
pressing member 10 and a second pressing member 20 having steel plates 12, 22,
in which
thermal wire heaters 13, 23 are built in, respectively, wherein a buffer
member 40 is attached
to the steel plate 22 attached to the second pressing member 20.

iron of the present invention. The present invention is characterized by a
hair iron
comprising a first pressing member 10 and a second pressing member 20 having
steel plates
12, 22, in which thermal wire heaters 13, 23 are built in, respectively,
wherein a buffer
member 40 is attached to the steel plate 22 attached to the second pressing
member 20.
The buffer member 40 is made of heat-resistant materials such as heat-
resistant
silicon, silver, TeflonTM or urethane rubber. The buffer member 40 may be
either attached
on the surface of the steel plate 22 or inserted in a groove 22a formed on the
surface of the
steel plate 22. Although not shown in the drawings, the buffer member 40 may
be attached
on each surface of the two steel plates 12, 22 of the first and second
pressing members 10, 20.
In addition to heat-resistant silicon, the buffer member 40 may be made of any
material that
is elastic and heat resistant.
External cases 11, 21 are attached to outside of the steel plates 12, 22,
respectively.
Each end of the first and second pressing members 10, 20 may open and shut by
a hinge 5.
A spacing stick 60 is fixed to the first pressing member 10. The spacing stick
60 has a
projecting part 61 at the end. The second pressing member 20 has a spacing
member 62,
which allows the spacing stick 60 to move up and down. The spacing between the
first
pressing member 10 and the second pressing member 20 can be adjusted by
pressing outside
of the first and second pressing members with fingers. At the bottom of the
spacing
member 62 is mounted a spring 63.
On the steel plate 22 to which the buffer member 40 is attached, a groove 22a
is
formed along the steel plate 22. Heat-resistant silicon is inserted into the
groove 22a as the
buffer member 40. The buffer member 40 has a projecting part 40a which
prevents the
buffer member 40 from being detached from the groove 22a. That is, the
projecting part 40a
is inserted into the groove 22a, and thus the buffer member 40 is not
detached.
Like other conventional hair irons, the hair iron of the present invention has
a
3

temperature controller 70, power supply wires, etc. as a means of controlling
temperature.
Detailed description thereabout is omitted, because it is well known in the
related art.
On the surface of the steel plates 12, 22 is formed a ceramic coating,
TeflonTM
coating or anodizing coating. The heat-resistant silicon used in the invention
can endure up
to 100-230 C.
Hereunder is given a description of how to straighten or roll hair using the
hair iron
of the present invention.
First, plug in the power supply to heat the steel plates 12, 22. While the
steel plates
12, 22 are heated, the temperature controller 70 maintains the temperature
adequately.
Then, locate hair in between the opposing fist and second pressing members 10,
20
and smoothly pool the hair iron while pressing the outside of the first and
second pressing
members with hand. At this point, hair is pressed in between the steel plate
12 and the
buffer member 40 and heat is transferred to the hair. Because the buffer
member 40 is made
of heat-resistant silicon, it is heat resistant and elastic. Thus, the hair
can be effectively
pressed. Consequently, hair can be straightened or rolled.
Hair located between the buffer member 40, which is attached on the steel
plate 22 of
the second pressing member 20, and the steel plate 12 is pressed well and
glides smoothly,
because the heat-resistant silicon is soft. Also, because the heat-resistant
silicon is elastic,
there will be no space between the buffer member 40 and the steel plate 22.
Also, because
the heat-resistant silicon is located between the metallic steel plates 12,
22, damage done to
hair by heat can be reduced. The buffer member 40 may be replaced with a new
one after
prolonged use.
The hair iron of the present invention has a buffer member made of heat-
resistant
silicon, which blocks direct contact of steel plates 12, 22. The buffer member
holds hair
smoothly and removes space between the steel plates. Also, hair damage can be
prevented.

Hair located between the buffer member 40, which is attached on the steel
plate 22 of the
second pressing member 20, and the steel plate 12 is pressed well and glides
smoothly,
because the heat-resistant silicon is soft. Also, because the heat-resistant
silicon is elastic,
there will be no space between the buffer member 40 and the steel plate 22.
Also, because
the heat-resistant silicon is located between the metallic steel plates 12,
22, damage done to
hair by heat can be reduced.
The buffer member of the present invention prevents hair form being pulled off
and
makes hair straightening or rolling more pleasant when using a hair iron.
While the present invention has been described in detail with reference to the
preferred
embodiments, those skilled in the art will appreciate that various
modifications and
substitutions can be made thereto without departing from the spirit and scope
of the present
invention as set forth in the appended claims.
