material which is subject to copyright protection. The copyright
owner has no objection to any reproduction by anyone of the patent
disclosure, as it appears in the United States Patent and Trademark
Office patent files or records, but otherwise reserves all

BACKGROUND OF THE PRESENT INVENTION
[0002] 1. Field of Invention
[0003] The present invention relates to a hair setter, and more
particular to a hair curling device, wherein the user is able to
drive the clamping arm to rotate 360.degree. around the heating
member via one hand operation in order to wind up the hair of the
user around the heating member in a tight and neat manner, such
that the user is able easily curl her hair easily in a "do it
yourself" manner. In addition, the clamping arm can be manually
driven manually or can be automatically driven by an electric motor
in two reversible directions.
[0004] 2. Description of Related Arts
[0005] A conventional hair curling device comprises a heating
barrel coaxially extended from an elongated handle, a clamp
pivotally coupled at the heating barrel, and a clamp operation arm
coupled at the clamp to move the clamp between an opened position
and a closed position. In order to operate the conventional hair
curling device, the user is able to pivotally move the clamp at the
opened position via the clamp operation arm to grasp a lock of hair
between the heating barrel and the clamp. Then, the user is able to
rotate the heating barrel by two hands in order to wind the hair
around the heating barrel. However, the operation of the
conventional hair curling device is troublesome and the lock of
hair is grasped and wound during the rotation of the heating
barrel.
[0006] Accordingly, there are two types of the clamp for the
conventional hair curling device.
[0007] The first one is that the clamp is coupled at the heating
barrel and is non-rotatable. During the operation of the hair
curling device, the clamp must be pivotally moved at the opened
position in order to grasp a lock of hair between the heating
barrel and the clamp. Then, the user is able to wind the lock of
hair around the heating barrel with the clamp through a two-hand
operation. Alternatively, the user is able to rotate the entire
hair curling device to wind the lock of hair around the heating
barrel with the clamp. The drawbacks of the conventional hair
curling device are that the operation thereof requires two-hand
operation such that the user will feel troublesome and tired to
curl her hairs. During the winding operation, the lock of hair
cannot be evenly and neatly wound around the heating barrel, such
that some hair at the lock may not be wound around the heating
barrel. As a result, it is difficult for the user to control the
desired tightness of the hairs when whirling the hairs around the
heating barrel. Furthermore, when the lock of hair is retained
between the clamp and the heating barrel, a clearance is formed
therebetween. In other words, when the heating barrel is heated up,
the heat thereat will not be evenly applied to the lock of hair
through the clearance in order to curl the hair at a desired
design.
[0008] The second type is that the clamp can be rotate around the
heating barrel, wherein a tubular metal frame is extended from the
handle to the heating barrel. Therefore, the heat generated from
the heating barrel will transmit to the handle through the metal
frame, which may burn the user's skin. In addition, the metal frame
will substantially increase the overall weight of the hair curling
device. The user may feel tired to hold the hair curling device
after a period of continuous use.
[0009] Furthermore, since the diameter size of the heating barrel
is relatively small, the temperature sensor must be located at the
handle and is electrically connected to the heating barrel via an
electric wire. Accordingly, the electric wire is retained at the
handle via a screw. In other words, when the heat is transmitted to
the handle, the screw will also be heated up to damage the electric
wire, which may cause a short circuit or even an electric shock.
Therefore, such configuration is unsafe for the user.
SUMMARY OF THE PRESENT INVENTION
[0010] In order to overcome the above mentioned disadvantages, the
invention provides a hair curling device, which can be operated by
one hand of the user and can secure the lock of hair being wound
around the heating member in a tight and neat manner. The hair
curling device can also minimize the clearance between the clamping
arm and the heating member, prevent the heat transmitted to the
handle member, and substantially reduce the overall weight of the
hair curling device. The connector between the handle member and
the heating member is made non-metal material and has a relatively
large installation space. The inner wall of the handle member is
connected to the connector via a plastic fastener to retain the
electric wire of the temperature sensor in position so as to
prevent the heat from the heating member being transmitted to the
electric wire.
[0011] Another advantage of the invention is to provide a hair
curling device which is an automatic hair curling device and can be
operated by one hand of the user to drive the clamping arm being
automatically rotated 360.degree. about the heating member so as to
whirl the lock of hair around the heating member. In particular,
when the two-directional-control operation button is depressed to
activate the electric motor, which is preferably a micro electric
motor, the clamping arm can be controlled to rotate about the
heating member at either clockwise direction or counter clockwise
direction, so as to whirl the lock of hair around the heating
member for curling the hairs.
[0012] Additional advantages and features of the invention will
become apparent from the description which follows, and may be
realized by means of the instrumentalities and combinations
particular point out in the appended claims.
[0013] According to the present invention, the foregoing and other
objects and advantages are attained by a hair curling device which
comprises a handle member, a heating member, a connector connecting
the handle member with the heating member, and a clamping arm
rotatable around the heating member in 360.degree.. The connector
is made of plastic (such as PPS) to connect the handle member with
the heating member. A rotatable hub unit comprises an upper
rotatable hub (made of nylon with 30% of fiberglass) and a lower
rotatable hub (made of nylon with 30% of fiberglass) being coupled
at the upper and lower portions of the connector. An operation
button (made of nylon with 30% of fiberglass) and a rotatable
clamping arm (made of nylon with 30% of fiberglass) are coupled at
an outer surface of the upper rotatable hub (made of nylon with 30%
of fiberglass) via a button cap (made of nylon with 30% of
fiberglass) to form a 360.degree. free rotatable clamping unit,
such that the rotatable clamping arm is rotatable about the heating
member. Accordingly, the clamping arm is coupled to the rotatable
hub unit via the operation button and is coupled to the connector
via the rotatable hub unit. During the operation of the hair
curling device, the PPS made connector and the nylon made rotatable
clamping unit will substantially reduce the heat being transmitted
from the heating member to the handle member. When the clamping arm
is rotated about the heating member, the clamping arm will guide
and comb the lock of hair to whirl the lock of hair around the
heating member neatly. The hair curling device of the present
invention further comprises a lock provided at the lower rotatable
hub to selectively lock up the rotatable hub unit with the handle
member. Therefore, when the lock is released, the clamping arm can
be freely rotated about the heating member at 360.degree. while the
handle member is held immovably. Or, when the lock is actuated, the
clamping arm can be driven to rotate by the rotational movement of
the handle member. In other words, the clamping arm and the handle
member are rotated at the same time. Since the clamping arm is
coupled at the connector, the user is able to operate the hair
curling device of the present invention by one hand to control the
curliness of the hairs easily and safely.
[0014] Another advantage of the invention is that the hair curling
device of the present invention can be operated by one hand of the
user, wherein the clamping arm can be tightly contacted with the
surface of the heating member to control the tightness of the hairs
therearound. The overall weight of the hair curling device will be
substantially reduced by the non-metal made connector which can
also reduce the heat being transmitted from the heating member to
the handle member for enhancing the safety of the hair curling
device.
[0015] In accordance with another aspect of the invention, the
present invention comprises a hair curling device, which comprises
a power operating arrangement provided between the handle member
and the heating member. The power operating arrangement comprises
an electric motor, a gear assembly operatively coupled with the
electric motor, and a rotatable hub unit driven by the electric
motor through the gear assembly, wherein a clamping arm is coupled
at the rotatable hub. Therefore, when the two-directional-control
operation button is depressed to activate the electric motor, the
clamping arm can be controlled to rotate about the heating member
via the rotatable hub at either clockwise direction or counter
clockwise direction, so as to whirl the lock of hair around the
heating member for curling the hairs.
[0016] Another advantage of the invention is that the hair curling
device of the present invention, which has a simple structural
configuration, can be operated by one hand of the user, wherein the
clamping arm can be automatically rotated around the heating member
at either clockwise direction or counter clockwise direction by a
depression of the operation button to whirl the lock of hair around
the heating member.
[0017] Still further objects and advantages will become apparent
from a consideration of the ensuing description and drawings.
[0018] These and other objectives, features, and advantages of the
present invention will become apparent from the following detailed
