Hair irons are tools utilized to change the structure of hair by applying heat. Different hair irons are utilized depending on the desired result. Three common hair irons are generally utilized in the art. Curling irons, utilizing a cylindrical heating barrel, are used to make hair curly. Straightening irons, commonly called straighteners or flat irons, are used to straighten hair. Crimping irons are used to create crimps of the desired size in the hair.
Flat irons work by breaking down the hair's hydrogen bonds found in the hair's cortex, which cause hair to bend and become curly. Once the bonds are broken, hair is prevented from holding its original, natural form, though the hydrogen bonds can re-form if exposed to moisture.
Existing flat irons, with heating plates typically manufactured of Teflon, ceramic, tourmaline, titanium, or other metal, employ handles that allow a user to compress hair between two heated plates formed by thermally conductive material. Known flat irons for styling hair typically include two paddle-like members each having a handle end and a heated end. The handle ends are joined to one another at a hinge, while the heated ends are free so they can be opened and closed away from and toward each other, respectively. The heated ends typically have a smooth, thermally conductive surface, such as metal, to transfer heat from an internal electrical heater to a user's hair when the hair is placed in contact with the thermally conductive surfaces, referred to as “heated plates.” Certain flat irons have smooth heated plates to impart a straightening style to a user's hair. In order to achieve the desired effect, a length of the user's hair is positioned between the two heated plates and, via the hinge, the plates are closed toward one another. The flat iron is drawn, typically away from the user's scalp, so that the hair runs through and is in contact with both plates. Heat from each plate is transferred to the hair. Generally, flat irons have power cords that plug into a wall outlet in order to power the heated plates. However, flat irons heated by butane elements and flat irons structured to utilize infrared technology are also known in the art. Known flat irons also have power and temperature controls on the handle of the iron itself which allow the user to set the desired temperature. As a result, since the user is holding the iron during use, there is a risk that the user will unintentionally or accidentally engage the power or temperature controls.
Most flat irons currently on the market are provided without a stand. During operation, it is a common for the user to rest the flat iron directly on a countertop, sink, or other surface when the iron is in a heated state. When the iron is not in use, the user may wrap the power cord around the iron, wind up the power cord, or bunch up the power cord as desired. There is an apparent risk in wrapping the power cord around the iron when the flat iron is in a heated state. This risk is also present if the cord is wound or bunched up near enough to the iron that heat from the plates can impact the cord, thereby damaging the cord and potentially causing a fire hazard. Known flat irons that are provided with or without a stand do not address this common shortcoming.
Existing flat iron stands allow the iron to be placed in the stand in one position, typically in a vertical position perpendicular to the supporting countertop surface. A flat iron in a vertical position is commonly preferred as it minimizes the footprint of the flat iron for storage. It is well known in the art that minimizing appliance footprints is preferred as commonly utilized hair appliances, such as flat irons, are generally stored in bathrooms where countertop space is at a premium. However, this storage structure does not take into account safety concerns. Specifically, when the flat iron is heated, by placing a flat iron in a vertical state, the heating plates are generally at a position which is convenient for a user to grab—a clear risk to the user which could result in burns. Therefore, when using a flat iron in a heated state, a user may desire to place the flat iron down horizontally, thereby positioning the heating plates at the furthest point from the user and encouraging the user to grab the flat iron at a non-heated point on the handle, closer to the hinge. However, without a stand structured to accept a flat iron in a horizontal state, a user often places the heated flat iron on a surface which is susceptible to damage as a result of the heat emanating from the heating plates. Furthermore, as previously mentioned, if the flat iron is placed in an insecure position on a countertop, the iron can be damaged, the cord can be damaged, or the iron can fall, creating risk to the operator as well as potential damage to property.
Known flat irons have temperature indicators or displays located on the flat iron. However, the known displays do not adequately and clearly indicate the temperature of the heated plates in certain circumstances and under certain conditions. If a user is not adequately apprised of the heated temperature of the heating plates, the flat iron may not be completely effective or may even be dangerous for use. Even in the case of known flat irons with stands, the controls are still positioned on the flat iron handles, rather than the stands which are better suited for providing a clear indication of the temperature of the heated plates.
In light of the foregoing, there is a need in the art for improved flat irons.
It is the object of the present invention to provide a flat iron and a base stand that overcome the disadvantages of the prior art. In the preferred embodiment of the present invention, the flat iron includes two handles, two heat plates, and an optional display. The base stand includes a top surface that supports the iron in either a secure vertical position or a secure horizontal position. The flat iron is generally structured to be positioned in the vertical position when not in use, and positioned in the horizontal position when in use. The vertical position limits the amount of horizontal space required by the appliance when the flat iron is positioned on a countertop and the horizontal position is structured to limit the risk of burns to the user. The base stand provides secure positioning of the flat iron in either a horizontal or vertical position, thereby allowing the user to select which position he or she prefers when the flat iron is in use or not in use. The base stand supports the flat iron in an elevated position above the countertop or other surface, thereby reducing the risk of damage to the surface or the user. The base stand further includes a display and temperature controls that allow a user to set and adjust the desired temperature of the heat plates. The base stand also includes a retraction mechanism for retracting the power cord connecting the iron to the base stand and a retraction mechanism for retracting the power cord connecting the base stand to a power outlet. While retraction mechanisms can be employed for either or both power cords, it is also contemplated by the present invention that non-retractable cords may be utilized in an alternate embodiment of the present invention.
Other objects, features, and characteristics of the present invention, as well as methods of operation and functions of the related elements of the structure and the combination of parts, will become more apparent upon consideration of the following detailed description with reference to the accompanying drawings, all of which form part of this specification.
The detailed description makes reference to the accompanying figures wherein:
The following presents a detailed description of the preferred and other embodiments of the present invention, and refers to the figures.

Base stand 200 further includes electronic circuitry encased within the interior of base 202. Base stand 200 further includes a power cord (not shown) which connects to a conventional power outlet and supplies power to the electronic circuitry within base 202. Partially inside base 202 is a retractable iron cord (not shown). The first end of the iron cord is connected to the electronic circuitry within base 202. The second end of the iron cord is connected to iron 100. The iron cord supplies power from the electronic circuitry to iron 100.
In the preferred embodiment, base stand 200 includes a mechanism for retracting the iron cord. The mechanism is contained within base 202 and preferably includes a spring and a spool, and is fastened to one end of the iron cord. The mechanism allows the opposite end of the iron cord (the end attached to iron 100) to be pulled from base stand 200. The user may pull iron 100 away from base stand 200 until the desired length of the iron cord has been reached. In the preferred embodiment, a user presses retract button 216 to trigger the retraction mechanism, which draws the iron cord back into base 202 as the user returns iron 100 to base stand 200.
In another embodiment, the mechanism retracts the iron cord once the user returns iron 100 to base stand 200. In this embodiment, a button (not shown) is located between front flat surface 204 and rear flat surface 206 that triggers the retraction mechanism when the button is pressed. As a result, when a user returns iron 100 to base stand 200, iron 100 presses down on the button (not shown) and the iron cord is automatically retracted. In some embodiments, when the desired length of the iron cord has been reached, the mechanism automatically secures the iron cord in place. When the iron cord is fully extended, the mechanism retracts the iron cord. Thus, when a user desires to have the iron cord retracted toward base stand 200, the user pulls the iron cord until it is fully extended, at which point the mechanism retracts the iron cord until iron 100 is within a short distance of base stand 200. In a similar embodiment, the retraction mechanism may include a button or similar device to be operated by a user which activates the retraction functionality, thereby allowing the user to enable the retraction mechanism. It should be appreciated that one or more alternative or additional structures may be used to retract the iron cord into base stand 200. In the preferred embodiment, base stand 200 also includes a retraction mechanism for retracting the power cord. The mechanism for retracting the power cord is similar and operates in similar fashion to the mechanism for retracting the iron cord. It should be appreciated that the mechanism for retracting the iron cord and/or the mechanism for retracting the power cord may be different and either or both may be omitted.
On/off button 208, first button 210, display 212 and second button 214 are disposed on base 202 and allow a user to control and monitor the temperature of iron 100. On/off button 208 is electronically coupled to electronic circuitry within base 202. In alternative embodiments, on/off button 208 may include a binary rocker switch, dial, touch sensor, or other suitable control. When on/off button 208 is set to the “ON” position, power is made available to display 212. First button 210 and second button 214 are electronically coupled to electronic circuitry within base 202 and preferably include conventional buttons. In alternative embodiments, one or more dials, switches, or other suitable controls may be used in place of first button 210 and second button 214.
In the preferred embodiment, display 212 includes a screen with light-emitting diode (LED) lights. In alternative embodiments, display 212 may include another suitable display capable of indicating a temperature via numerals, text, audible signals, or graphics. In the preferred embodiment, base light 220 is positioned at the underside of base stand 200 and is structured to emit a colored light representing the temperature of iron 100. Specifically, base light 220 may emit blue light for low temperature, yellow light for moderate temperature, and red light for high temperature. Base light 220 acts as a safety feature to notify a user that iron 100 is hot. Base light 220 preferably remains lit even after iron 100 is turned off, thereby providing a warning to nearby people that first heat plate 106 and second heat plate 108 are hot. Base light 220 may also serve as a nightlight when the unit is not in use. In such embodiments, nightlight switch 218 can be switched to the ON position to turn on base light 220. Base light 220 will then remain on until nightlight switch 218 is switched to the OFF position. In some embodiments, base light 220 may be replaced by one or more other light sources and may be positioned elsewhere on base stand 200 or iron 100. In some embodiments, a dimmer switch may be used in place of, or in addition to, nightlight switch 218 and used to set the color or brightness of base light 220.
In the preferred embodiment, first temperature setting button or first button 210 and second temperature setting button or second button 214, are used to set the desired temperature of first heat plate 106 and second heat plate 108. Specifically, when first button 210 is pressed, the desired temperature of first heat plate 106 and second heat plate 108 is raised. When second button 214 is pressed, the desired temperature of first heat plate 106 and second heat plate 108 is lowered. In one embodiment, the desired temperature of first heat plate 106 and second heat plate 108 may be raised and lowered among a few preset temperatures. In this embodiment, exemplary settings may be 350 degrees, 370 degrees, 390 degrees, and 410 degrees Fahrenheit, or may be referred to by terms such as “low,” “medium,” “high,” and “maximum.” In an alternative embodiment, the desired temperature of first heat plate 106 and second heat plate 108 may be raised and lowered in increments, such as by individual degrees. The desired temperature is displayed on display 212. Time is required for first heat plate 106 and second heat plate 108 to be heated up to the desired temperature, so the desired temperature and actual temperature are not always equal. For this reason, the actual temperature is preferably also displayed to the user via display 212.
Iron 100 and/or base stand 200 preferably include an audio device for emitting sound. In the preferred embodiment, an audio device is contained within second handle 102. The audio device beeps or otherwise emits a sound when first heat plate 106 and second heat plate 108 have reached the desired temperature. In some embodiments, sound may be generated for the duration of time that first heat plate 106 and second heat plate 108 are at or above a particular temperature. In the preferred embodiment, the audio device also beeps when the iron 100 is turned on or off.
Iron 100 and/or base stand 200 preferably include a timer that detects the amount of time between user activity. In the preferred embodiment, a timer is embodied in the electronic circuitry within base stand 200 and monitors the amount of time after a user presses on/off button 208, first button 210 or second button 214. In an alternative embodiment, a motion sensor in iron 100 detects movement of iron 100 by a user, and the timer monitors the amount of time after a user moves iron 100. When the timer determines that a threshold amount of time has passed since the last user activity, the timer instructs iron 100 and base stand 200 to no longer provide heat or power to first heat plate 106 and second heat plate 108. In the preferred embodiment, display 212 will remain operational and indicate the current temperature of first heat plate 106 and second heat plate 108. In an alternative embodiment, the timer may shut off iron 100 and/or base stand 200 completely.

According to an embodiment, to reduce the likelihood of iron 100 falling or being placed in an unsafe position, iron 100 is structured so that the center of mass is in the center of iron 100 or on the side of iron 100 opposite first heat plate 106 and second heat plate 108. As an additional or alternative embodiment, iron 100 is structured so that it fits horizontally onto base stand 200 only when placed in a specific orientation. For example, the structure of first handle 102 and/or second handle 104 may be shaped so that they fit onto front flat surface 204 and rear flat surface 206 only when first heat plate 106 and second heat plate 108 are positioned away from base stand 200, such as in the configuration depicted in
To properly use iron 100, a user first plugs in the power cord to a conventional power outlet. The user then activates the iron 100 by pressing on/off button 208. The user then selects the desired temperature of iron 100 by pressing first button 210 to raise the temperature setting and by pressing second button 214 to lower the temperature setting. Display 212 displays the current temperature setting. Once first heat plate 106 and second heat plate 108 have reached the desired temperature, display 212 will blink or otherwise indicate that the desired temperature has been reached. The user picks up iron 100 by gripping first handle 102 and second handle 104. As the user pulls iron 100 away from base stand 200, the iron cord is extended from base stand 200. The user applies first heat plate 106 and second heat plate 108 to the user's hair as desired. During use, first heat plate 106 and second heat plate 108 are maintained at the desired temperature.
The user may return iron 100 to base stand 200 by placing it on base stand 200 in the vertical position as depicted in

An audio device generates a sound to notify the user that the temperature has reached 390 degrees. It should be appreciated that various sounds may be used to indicate one or more temperatures, and a sound may be generated each time a predetermined temperature is reached. One of skill in the art will appreciate that variations to the display and audio may be made without departing from the principles disclosed herein.

The ion generator IG1 with a control and a button BC1 is shown positioned in both iron 100 and base stand 200. However, the ion generator IG1 with a control and a button BC1 exists, in one embodiment, only in the iron 100. In other embodiments, the generator, the control, and the button BC1 are each separate and distributed separately in either the iron 100 or the base stand 200 or both. That is in one embodiment the generator IG1 with the control is located in the iron 100 with the button BC1, while a second button BC1 and also the control exist in the base stand 200. In another embodiment, the control is entirely in the base stand, and the button BC1 appears in both or only one of the iron and base stand. In an embodiment, the ion generator IG1 with control in the base stand 200 include only the electronic control that controls the ion generator IG1 in the iron 100; with further control for the ion generator IG1 by the control in the iron 100. The button BC1 in one embodiment appears only in the iron 100, or the base stand 200.

Base stand 200 and base 202 further includes electronic circuitry EC1 encased within the interior of base 202. Base stand 200 further includes a power cord PC1 which connects to a conventional power outlet and supplies power to the electronic circuitry EC1 within base 202. Partially or entirely inside base 202 is a retractable iron cord R1C1. The first end of the iron cord R1C1 is connected to the electronic circuitry EC1 within base 202. The second end of the iron cord is connected to iron 100. The iron cord supplies power from the electronic circuitry EC1 to iron 100.
In the preferred embodiment, base stand 200 includes a retracting mechanism RM1 for retracting the iron cord RIC1. The retracting mechanism RM1 is contained within base 202 and preferably includes a spring and a spool, and is fastened to one end of the iron cord RIC1. The retracting mechanism RM1 allows the opposite end of the iron cord IRC1 attached to iron 100 to be pulled from base stand 200.
The user may pull iron 100 away from base stand 200 until the desired length of the iron cord has been reached. In the preferred embodiment, a user presses retract button 216 to trigger the retraction mechanism, which draws the iron cord back into base 202 as the user returns iron 100 to base stand 200.
In another embodiment, the retracting mechanism RM1 retracts the iron cord RIC1 once the user returns iron 100 to base stand 200. In this embodiment, a button RB1 located between front flat surface 204 and rear flat surface 206 that triggers the retracting mechanism RM1 when the button RB1 is pressed. As a result, when a user returns iron 100 to base stand 200, iron 100 presses down on the button RB1 and the iron cord RIC1 is automatically retracted. In some embodiments, when the desired length of the iron cord has been reached, the retracting mechanism RM1 automatically secures the iron cord RIC1 in place. When the iron cord RIC1 is fully extended, the retracting mechanism RM1 retracts the iron cord. Thus, when a user desires to have the iron cord RIC1 retracted toward base stand 200, the user pulls the iron cord until it is fully extended, at which point the retracting mechanism RM1 retracts the iron cord until iron 100 is within a short distance of base stand 200. In a similar embodiment, the retracting mechanism RM1 may include a button or similar device to be operated by a user which activates the retraction functionality, thereby allowing the user to enable the retraction mechanism. In the preferred embodiment, base stand 200 also includes a retraction mechanism RM2 for retracting the power cord PC1. The retracting mechanism RM2 for retracting the power cord PC1 is similar and operates in similar fashion to the mechanism for retracting the iron cord RIC1.
On/off button 208, temperature-increase-control and first button 210, display 212, temperature-decrease-control and second button 214, and retract button 216. are disposed on base 202 and allow a user to control and monitor the temperature of iron 100. On/off button 208 is electronically coupled to electronic circuitry within base 202.
