Description

TITLE: ROD FOR HAIR CURL

Technological Field

[1] This device is a rod for hair curls, which can be widely used in salons for

hair perms and treating curly hair.

[2]

Background Art

[3] The rod for hair curls to be introduced here was developed for usage of

making curls in or perming the hair. It is an improved version of the

existing hair-curl rods, with increased efficiency and ability to create new

forms of curls.

[4] The most commonly used type of hair-curl rods used in salons and

homes for making curls in the hair is the one in the circular cylinder form

(11) with indentations in the middle (113) and grooves for fixing rubber

bands at both the ends (121) of the cylindrical body (11) (See Figures 6

and 7). The hair-curler (e.g. hair design professional) places hair (2) on

the outer body of the rod (1), starts rolling the hair from the end upward and fixes the hair using a rubber band (not shown in the figure). By

leaving hair fixed on the rod for a specific period of time, the hair

becomes curly, i.e. permed. This commonly used type of the hair-curling

rods (11) is made of rubber or urethane in order to better hold the hair

(2) by using such materials that increase frictions on the rod body (11).

There is a lateral plate (115) on the inside where the rod body (11) and

the handle (12) meet in order to cover the inside of the rod body (11).

[5] However, using such a type of the hair-curling rods is complicated and

does not fixate the hair either. It is extremely difficult to form desired type

of curls using those curling rods, making it almost entirely up to the skills

and expertise of the hair-curler. Usage of such rods also limits the

movements of the customer, requiring for improvements in the overall

curling tools.

[6]

Disclosure of Invention

[7] This device was invented in order to resolve such aforementioned

problems. Designed structurally functional and easy for use, it enables

the hair professional to create the desired and accurate curls; is easy for anyone to use in curling the hair; minimizes the inconvenience in

movements of the customer; and reduces the harmful effects of

chemicals used to perm the hair.

[8] For this, this device elongated the length of the existing type of the

curling rods so that the hair can be curled more easily. It attached the

handles at the end(s) of the rod body, while also adopting a structure

that enables ventilation inside the rod.

Best mode for carrying out the invention

[29] Figure 1 shows a structural view of the device, and Figure 2 contains a sectional view of the Figure 1 along the A-A line.

[30] As shown in the figure, the subject rod (1) is composed of various

spokes(111) formed by indentation and protrusion; a body (11) in a

cylindrical form with a cavity (112) in between the aforementioned

spokes(111); and a supporting part (113) around the edges of the ends

of the aforementioned body (11). There is a multiple number of grooves

(121) at each end of the body for fixing the hair with rubber bands; a

multiple number of protrusions (122) in the perpendicular angles to the

circumference; and a handle (121) that connects the body (11) and the

end humps (123).

[31 ] Figure 3 shows another structural view of the device.

[32] A notable characteristic with the device is that the handle (12) is located

between the both ends of the rod body (11).

[33] Figure 4 is another structural view of the device.

[34] A notable characteristic with the device is that there are grooves (14)

along the length of the rod body (11).

[35] The process of curling hair using each characteristic part of the device

can be described as follows: [36] When the hair professional at a salon or home needs to perm or curl the

hair of a customer, the first thing the customer does is to wash hair,

which can be omitted depending on situations. The professional then

spreads a softener over the head in order to soften the hair (2). He or

she then surrounds the hair with a piece of paper or felt and starts rolling

the hair with the rod (1). The rod body of this invention (11) is indented.

A cavity is in between multiple spokes (111) at both ends. The uneven

outer part of the body (11) increases friction, which is crucial to fix the

hair covered by paper or felt. The uneven body (11) also forms fine

angles in the curled hair so that the curls can be maintained for much

longer. The spokes (111 , 111...) can be easily handled due to a cavity in

between them (112). The rod, around which the hair (2) is rolled, has a

reduced diameter if grabbed tightly, but it is restored in terms of the

diameter again after letting it go of the hand. Such a characteristic

enables the rod to fix the hair better. Also, the existing type of the rod

shown in Figure 6 creates oval curls after removing the rod (1) as it

concentrates the hair (2) into the crown-like shape in its middle. The rod

of this invention (1), however, can create even curls since its body (11) is straight.

[37] Furthermore, because the handle (12) straightly connects the body (11)

and the end humps (123) aforementioned between the multiple grooves

(121) and multiple protrusions in the perpendicular angle to the

circumference, the hair professional can easily rotate the rod by

grabbing the handle despite the slippery materials, such as chemicals

and oil, on his or her hand. The end humps (123) between the rod body

(11) and the handle (12) prevent the hair from getting slipped out of the

rod. Also, even if a rubber band is tied around the hair and the rod in

order to fix the hair (2) better on the rod body (11), such a design of the

device prevents the hair (2) from getting unshapely from the rubber band

pressure.

[38] In this case of the device with handles on both ends of the body (11) as

shown in Figure 3, the grooves between the handles (12, 12) helps to fix

the hair (2) on the rod (1) by allowing the rubber band to tie the hair

around. In case of the device with only one handle as shown in Figures

1 and 2, the hair (2) can be fixed by using glue or any other adhesive

materials in between the rolled hair curls and the upper part of the hair (2). The dried hair (2) is extracted from the body (11) of the rod (1). Here,

the hair can be easily extracted if the rod body (11) has a taper which

makes the rod thinner around the area of the handle (12).

[39] An oxidizer is spread over the head in order to maintain the curls when

the hair (2) is rolled (whether the hair is stilled rolled around the rod or

detached from it). The cavity inside the rod (11) in the cylindrical form

maximizes the oxidizer effect by allowing its foam to penetrate into the

hair layers through the cavities (112) formed in between the spokes

(111) (the existing type of hair rods does not allow penetration of the

chemical into the interior part of the rod body (11) since the inside of

those rods is not empty or since there are lateral plates (115) around the

rod body (11)). The cavities (112) also allow ventilation, assisting the

oxidizing effects. As shown in Figure 5, the indented, uneven rod (1) of

this invention has spokes (111) that contacts the hair (2) only partially.

The little grooves in the rod minimizes the softener (shown in small black

dots in Figure 5) remaining between the hair (2), the rod (1) and the

spokes(111) in order to protect the hair. This also minimizes the contact

between the oxidizer, which acts to maintain the curls, and the pre- spread softener so that the perm effects can last longer.

[40] Although the rod body (11) is composed of the spokes (111) and the

cavities (112), there are supporting parts (113) around the rims of the

ends of the body (11) so that the spokes (111) and the cavities (112) can

be combined to the rod body (11). In addition, as shown in Figure 4, the

grooves (14) along the rod body (11) allows the body contraction without

a taper or even at small angles so that the rolled hair (2) can easily be

pulled out of the body (11) of the rod (1).
