Electric Hair Curling Iron
The present invention provides an electric hair curling device comprising a main handle, a cylindrical barrel for emitting heat operationally, a clamp member extending along one side of the cylindrical barrel which is shaped cylindrically to complement the shape of the barrel and a thermally insulated tip coupled to the cylindrical barrel. The thermally insulated tip is rotatable relative to the cylindrical barrel and is shaped as a small handle for gripping purpose. During operation, one of the user hand rolls the main handle, while the other hand holds the thermally insulated tip, thus providing a steady support which makes the overall curling process easier and less tiring for the user.

This application claims the benefit of Singapore patent application entitled “Electric Hair Curling Iron” filed on 13 Apr. 2010 having application number 201002670-6.
FIELD OF THE INVENTIONThe present invention generally relates to an electric hair curling device, and in particular to a rotatable electric hair curling device.
BACKGROUNDHair iron is a hairstyling tool used to change the structure of the hair through heat. There are two types of hair irons; flat or straightening irons and curling irons. As its name implied, straightening irons are used to straighten the hair and curling irons are used to create waves or curls in the hair.
Various types of curling irons or curling tongs are available in the market. During operation, a small portion of hair is clamped between a heated cylindrical barrel and a clamp member. The curling iron is then rolled up towards the hair root so that the hair is wrapped around the heated barrel. With heat, the hair is held around the curling iron for a few seconds and once the curl is formed, the hair can be unwrapped from the curling irons.
U.S. Pat. No. 4,565,916 assigned to Matshushita Electric Works, Ltd discloses an electric hair curling iron with a rotatable power cord. The electric power supply cord is connected to the electrically heated rod by a rotatable connector located on the end of the first handle. The axis of rotation of the connector is designed to be coaxial with the centerline between the two handles and to be in the same plane as the pivotal connection between the handles, such that the hair curling iron can be rotated without twisting the power cord.
U.S. Pat. No. 4,604,514 assigned to Windmere Corporation discloses an electric curling iron with rotatable main handle and clamp handle for enabling the cylinder and the clamp member to be rotated within the hand of the user while the hair is clamped between the clamp member and the cylinder. The main and clamp handle are each equipped with a locking mechanism selectively movable between a first position locking the respective handle against rotation and a second position wherein the respective handles are free to rotate.
SUMMARYThe following presents a simplified summary to provide a basic understanding of the present invention. This summary is not an extensive overview of the invention and is not intended to identify key features of the invention. Rather, it is to present some of the inventive concepts of this invention in a generalized form as a prelude to the detailed description that is to follow.
The present invention provides an electric hair curling iron. According to one aspect of the invention, the electric hair curling device comprises a main handle, a cylindrical barrel attached to the main handle at the proximal end for emitting heat operationally, a clamp member extending along one side of said barrel and is shaped cylindrically to complement a shape of the barrel, and a thermally insulated tip coupled to the cylindrical barrel, which is rotatable relative to the cylindrical barrel.
In one embodiment of the present invention, the electric hair curling device further comprises an electrical cable for supplying electrical power, which is coupled to a distal end of the main handle.
In another embodiment of the present invention, the thermally insulated tip is configured as a small handle for gripping during operation.
In yet another embodiment of the present invention, the cylindrical barrel and the electrical cable are rotatable relative to the main handle.
The objectives and advantages of the present invention will become apparent from the following detailed description of embodiments thereof in connection with the accompanying drawings.
Preferred embodiments according to the present invention will now be described with reference to the figures accompanied herein, in which like reference numerals denote like elements;
Embodiments of the present invention shall now be described in detail, with reference to the attached drawings. It is to be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the illustrated device, and such further applications of the principles of the invention as illustrated therein being contemplated as would normally occur to one skilled in the art to which the invention relates.
The clamp member 30 is pivotally mounted at a short distance from the proximal end on the cylindrical barrel 20 with a clamp plate 32 extends along one side of the cylindrical barrel 20. The clamp plate 32 is cylindrically shaped to complement the curve of the cylindrical barrel 20. The clamp member 30 is spring loaded at the pivot to keep the clamp plate 32 on the cylindrical barrel 20. A clamp handle 40 extended towards the opposing side of the clamp plate 32 and projected on the main handle 10 is provided for user handling. When the clamp handle 40 is pressed against the main handle 10, the clamp plate 32 is pivotally lifted to open the clamp member 30.
Typically, the main handle 10, on top of being a handle, is also a housing for components, and the controlling means of the electric hair-curling device 1 may also be disposed at the proximal end of the handle 10. In accordance with a further embodiment, the electric hair-curling device may further provide a display screen for showing operating states and other relevant information.
The electrical cable 60 for supplying electrical power is coupled to a distal end of the main handle 10. It may be desired that the electrical cable 60 be configured to be rotatable about the axis against the main handle 10 in an alternative embodiment.
In a further embodiment, the thermally insulated tip 50 can be configured as a relatively small handle for better gripping. The thermally insulated tip 50 can further be shaped ergonomically for holding comfort. The thermally insulated tip 50 can be any thermally insulated means that rotatably attached to the cylindrical barrel 50 such that it is rotatable freely about the axis against the cylindrical barrel 50.
While specific embodiments have been described and illustrated, it is understood that many changes, modifications, variations and combinations thereof could be made to the present invention without departing from the scope of the invention.
