Description
- This disclosure is generally related to hair styling appliances and devices, and methods for using the same.
- Heated curling irons, flat irons, and hair straighteners are commonly used in styling hair and may be used to create a wide variety of hair styles. Such appliances, for example, may be used to impart a curl that does not naturally occur in someone's hair, or to straighten someone's hair to remove a naturally occurring kink or curl. More specifically, a circular or semicircular-shaped curl can be created by wrapping hair about the outer surface of a heated cylindrically shaped curling iron.
- However, prolonged use of traditional curling irons (e.g., by hair stylists at a salon) can lead to muscle fatigue and/or result in injury. Furthermore, traditional curling irons can be unwieldy and difficult to operate, often times requiring a user to contort their arms, head and/or shoulders during use, which may prevent the appliance from being properly used and may also result in muscle fatigue and/or injury to the user. These issues with traditional curling irons are particularly problematic when traditional curling irons are used to self-style hair (as opposed to using the curling iron to style another person's hair). Therefore, what is needed is an effective and efficient curling iron that facilitates extended use and self-styling.
- The present invention is directed to an adjustable curling iron that may be suitable for extended use and/or facilitate effortless self-styling, as well as a method for using the same. In a first embodiment, an adjustable curling iron is disclosed comprising a handle assembly comprising a proximal end configured to receive a power supply; a distal end; and one or more switches mounted on the surface of the handle; a heating rod comprising a first end and a second end; a cylindrical housing extending from the first end toward the second end; a tip positioned at the second end; and a heating element connected to the power supply and extending within the cylindrical housing along its length; and a coupling assembly configured to engage the distal end of the handle assembly and the first end of the heating rod, and further configured to adjust the position of the heating rod from a first position, wherein a longitudinal axis of the heating rod is substantially parallel to a longitudinal axis of the handle assembly, to a second position, wherein an angle formed between the longitudinal axis of the heating rod and the longitudinal axis of the handle assembly is between 90 degrees and 150 degrees.
- In another aspect of the invention, a method of styling hair is disclosed, the method comprising the steps of providing an adjustable curling iron of the present invention; contacting the hair with the housing when the heating rod is in the first position; adjusting the heating rod from the first position to the second position; and contacting the hair with the housing when the heating rod is in the second position.
- The accompanying drawings, which are incorporated herein and form part of the specification, illustrate the present invention and, together with the description, further serve to explain the principles of the invention and to enable a person skilled in the relevant art(s) to make and use the invention.

FIGS. 1 and 2 illustrate a first embodiment of anadjustable curling iron 100. Theadjustable curling iron 100 may include ahandle assembly 200, aheating rod 300, and acoupling assembly 400. Thecoupling assembly 400 may be configured to engage thehandle assembly 200 andheating rod 300 and allow for the adjustment of thehandle assembly 200 andheating rod 300 relative to one another. In this way, the user is able to choose the configuration that is most comfortable to them, thereby improving ease of use and reducing the stress experienced by the user. - In some embodiments, the
handle assembly 200 may have aproximal end 201 and adistal end 202, and may be configured to receive apower supply 204. As illustrated inFIGS. 1 and 2 , thepower supply 204 may be received at theproximal end 201 of thehandle assembly 200, where it may be electrically coupled to power circuitry. Thepower supply 204 may be received at any positions of thehandle assembly 200, for example, along the length of thehandle assembly 200. Thepower supply 204 may also be attached to thehandle assembly 200 using a coupling assembly, which may provide for the flexible attachment of thehandle assembly 200 to thepower supply 204. Thehandle assembly 200 may also be provided with one ormore buttons 203 that a user can manipulate to adjust performance parameters of theadjustable curling iron 100. Thebuttons 203, for example, may be electrically coupled to the power circuitry of theadjustable curling iron 100, which may be able to control the temperature of theheating rod 300 by adjusting the amount of power supplied to the heating element by the power circuitry. - The
buttons 203 may be mounted on the surface of thehandle assembly 200, or may otherwise be disposed such that the user can manipulate theswitches 203 when holding the handle assembly. Thebuttons 203, for example and without limitation, may be provided as mechanical switches and/or capacitive buttons. In some embodiments, thehandle assembly 200 may additionally, or alternatively, be provided with an interactive display (e.g., a capacitive touchscreen display) and may present the user with a graphical user interface (GUI) through which the user may control performance of the device. In such cases,buttons 203 may be provided as part of the GUI. - By way of example, with reference to
FIGS. 1 and 2 , thehandle assembly 200 may have a power button, a ‘+’ button, a ‘−’ button and a mode button. The power button may be used to power on or power off theadjustable curling iron 100, the ‘+’ and ‘−’ buttons may be used to increase or decrease its operating temperature, and the mode button may change its mode of operation. Pressing the ‘+’/‘−’ buttons, for instance, may incrementally adjust the operating temperature of the adjustable curling iron 100 (e.g., increasing or decreasing the temperature by 5°) or cycle between pre-defined temperature settings of the adjustable curling iron 100 (e.g., cycling between 390°, 410°, 430° and 450°). As another example, pressing the mode button once may allow the user to set an automatic shut-off time. Further, where a GUI is provided through an interactive display, pressing the mode button twice may return the user to a previous screen or a home screen of the GUI. - In some embodiments, some or all of the
buttons 203 may be placed into a ‘locked’ mode wherein their functionality is disabled so that a user does not inadvertently adjust the performance parameters of theadjustable curling iron 100 during use. Thebuttons 203 may then be ‘unlocked’ to resume normal functionality. In some embodiments, one or more of thebuttons 203 may be ‘locked’ and ‘unlocked’ by toggling a mechanical switch. In other embodiments,buttons 203 may be ‘locked’ and ‘unlocked’ based on a pattern of button presses. By way of example, pressing and holding the power button for a short period of time (e.g., between 2-4 seconds) or pressing the power button in rapid succession (e.g., quickly pressing the power button 5 times) may lock/unlock the mode and ‘+’/‘−’ buttons. In some embodiments, thebuttons 203 may automatically assume the ‘locked’ mode after a period of inactivity has been detected (e.g., if nobutton 203 is pressed for 1 minute). - The
heating rod 300, in turn, may have afirst end 301 and asecond end 302, and may include ahousing 303 extending from thefirst end 301 to thesecond end 302. Thehousing 303 may contain a heating element that extends along its entire length. Theheating rod 300 may also be provided with atip 304, which may be located at thesecond end 302 of theheating rod 300. Thetip 304 may be formed of a material that does not conduct a significant amount of heat, whereby a user can safely touch the tip during operation without suffering any burns or experiencing discomfort. As illustrated inFIGS. 1 and 2 , thehousing 303 may have a cylindrical shape of constant diameter. But the invention is not thus limited, and thehousing 303 may take other suitable shapes. -
FIGS. 3 and 4 , for instance, illustrate a second embodiment of anadjustable curling iron 100 that includes structural and functional features similar to those described above with respect to the first embodiment illustrated inFIGS. 1 and 2 . But in contrast to the first embodiment, thehousing 303 of theheating rod 300 may have a tapered cylindrical (or truncated conical) shape. As illustrated inFIGS. 3 and 4 , thehousing 303 may taper from thefirst end 301 to thesecond end 302, whereby the diameter of thehousing 303 at thesecond end 302 may be smaller than the diameter of thehousing 303 at thefirst end 301. In yet other embodiments, thehousing 303 may be ‘bubbled,’ having spherical bubbles along its length from thefirst end 301 to thesecond end 302. - As for the
coupling assembly 400, the term “coupling assembly” may generally refer to a component configured to facilitate the connection of ahandle assembly 200 and aheating rod 300. As illustrated inFIGS. 1-4 , thecoupling assembly 400 may engage thehandle assembly 200 at itsdistal end 202 and theheating rod 300 at itsfirst end 301. The structure of thecoupling assembly 400 may allow wiring and/or other electrical components to be run from thehandle assembly 200 to theheating rod 300, and may, for example, provide a channel or conduit for doing so. Thecoupling assembly 400 may also be configured to allow a user to adjust the position of theheating rod 300 relative to thehandle assembly 200, whereby an angle is formed between the longitudinal axis of theheating rod 300 and the longitudinal axis of thehandle assembly 200.FIGS. 1 and 3 , for example, illustrate anadjustable curling iron 100 in a first position wherein a longitudinal axis of theheating rod 300 is substantially parallel to a longitudinal axis of thehandle assembly 200.FIGS. 2 and 4 , similarly, illustrate theadjustable curling iron 100 in a corresponding second position wherein an angle is formed between the longitudinal axis of theheating rod 300 and the longitudinal axis of thehandle assembly 200. - The range of possible adjustment positions may vary depending on the embodiment. For example, in some embodiments, the
coupling assembly 400 may allow the user to adjust the relative position of theheating rod 300 and handle assembly 200 from anywhere between 180° and 90°. While in others, the adjustment range may be larger (e.g., between 270° and 90°) or smaller (e.g., between 150° and 120°). Furthermore, some embodiments, may allow the relative position of theheating rod 300 and handleassembly 200 to be adjusted in a continuous fashion, while others may only allow for adjustment between a set number of positions. Thecoupling assembly 400, for example, may only allow the relative position between theheating rod 300 and handleassembly 200 to be adjusted to form an angle of either 90°, 120°, 150°, or 180°. -
FIGS. 5 and 6 illustrate an exploded view of thecoupling assembly 400 of the first and second embodiments of the adjustable curling iron. As illustrated inFIGS. 5 and 6 , thecoupling assembly 400 may be a two-part construction, for example, having top and bottomcomponent housing portions coupling assembly 400.
