This application claims the benefit of U.S. Provisional Application No. 61/612,883 filed Mar. 19, 2012 and U.S. Provisional Application No. 61/613,257 filed Mar. 20, 2012, each of which are incorporated herein in their entireties by reference.
BACKGROUND1. Field
Some of the present embodiments relate to hair styling devices, for example, hair straightening devices and pressing irons for straightening and/or pressing hair.
2. Description of the Related Art
A variety of devices are available for styling hair, such as curling irons, curlers, flat irons, hair straighteners, blow dryers, etc. Many of these devices function by incorporating an internal or external heating source for heating a surface of the device that contacts the hair to treat or style it. Other devices, such as blow dryers, heat and blow a stream of air onto the hair.
Thick, coarse, ethnic, curly, and/or kinky hair is particularly difficult to straighten properly with a typical flat plate iron type of hair-straightener. This is particularly true for hair typical to people of African, Latin, and Hispanic descent as well as other hair types. In some instances, hair with these types of textures can cause sticking or tangling in the hair straightening device during straightening. Thicker hair may also not be evenly or properly heated or straightened by the flat plate iron type device.
SUMMARYAn aspect of at least one of the inventions disclosed herein includes the realization that certain configurations of the heating surfaces of pressing-type hair straightening devices with blades incorporated into one or more heated plates can provide better performance, requiring less time and fewer passes to obtain the desired straightening and/or pressing. For example, some known pressing-type hair straightening/pressing devices (e.g., typical flat plate iron) can include teeth or spikes.
Another aspect of at least one of the present inventions includes the realization that using heating blades greatly reduces sticking and tangling that is associated with hair straightening devices that include teeth. Thus, in some embodiments, a hair straightening device includes one or more heating portions with blade-shaped heated surfaces. Such a configuration has been found to reduce sticking and tangling, thereby making it easier to straighten and/or press to the desired degree, hair that is thick, coarse, ethnic, curly, and/or kinky.
Yet another aspect of at least one of the inventions disclosed herein includes the realization that some hair (e.g., thick, coarse, ethnic, curly, and/or kinky hair, etc.) can be more easily straightened with a pressing type hair straightener device if more than one temperature setting is used. Thus, for example, some hair that is particularly coarse, curly and/or kinky can be more difficult to straighten by passing a known pressing type straightening iron (e.g., the typical flat plate iron) over the hair. It has been found that starting with a first temperature, and then making additional passes over the hair with an iron incorporating a heated plate with blades can help obtain the desired straightness or pressing more quickly (e.g., with fewer passes).
Thus, in some embodiments, a hair straightening and/or pressing device can have a first arm and a second arm extending along first and second longitudinal axes, respectively, and each including proximal and distal ends. The first and second arms can be pivotally or hingedly coupled at the proximal ends allowing the hair straightening and/or pressing device to be moveable between open and closed positions. The first arm can include a first heated surface and the second arm can include a second heated surface. A plurality of parallel and closely spaced blades can extend laterally across the first surface of the first arm in a direction transverse to the longitudinal axis. In some embodiments, a portion of the blades of the first arm contact a portion of the second surface of the second arm when the hair straightening and/or pressing device is in the closed position.
In some embodiments, the second surface comprises a smooth featureless plate. In some embodiments, the blades have a rounded top edge. In other embodiments, the blades have a flat top edge. While in some embodiments, the blades can have a pointed top edge.
In some implementations, the hair straightening and/or pressing device further includes first and second surfaces forming a flat nesting relationship when the hair straightening device is in the closed position. In certain embodiments, the first and second surfaces form a convex/concave shaped nesting relationship when the hair straightening and/or pressing device is in the closed position.
In some embodiments, a hair straightening and/or pressing device includes a first arm and a second arm having proximal and distal ends. The first and second arms are pivotally coupled at the proximal ends allowing the hair straightening and/or pressing device to be configurable into an open or closed position. The first arm can include a first surface and the second arm can include a second surface. One or both surfaces can be heated. The hair straightening and/or pressing device can further include at least a first and second temperature setting selectable by the user, wherein the one or more settings are better for straightening a particular type and/or condition of hair. For example, in some embodiments, relaxed hair requires less heat (e.g., lower temperature setting) than natural hair (e.g., higher temperature setting) for straightening and/or pressing. For example, but without limitation, the first temperature setting can be less than the second temperature setting yet still be sufficient for pressing and/or straightening chemically treated hair.
In some implementations, the hair straightening and/or pressing device can further include indicia to indicate a position for each of the first and second temperature settings. In some embodiments, the hair straightening device can be used with or in conjunction with a pressing oil in order to further assist with straightening and/or pressing hair.

With reference to
The connection 12 at the proximal ends 8, 10 can be any type of hinge type mechanism, such as a loaded spring, that biases apart or maintains the distal ends 14, 16 of first and second arms 4, 6 of the hair straightening device 2 in a generally open position, spaced a distance apart from each other. The connection 12 can be configured to maintain or bias the first and second arms 4, 6 away or apart from each other. Additionally, the connection 12 can be a rod, shaft or pin that allows one arm to move, rotate, and/or pivot relative to the other arm. A user can apply pressure or a closing force in an opposite direction of the biasing force of the pivotal connection 12 to close or push together the first and second arms 4, 6.
In some embodiments, a portion of the first and second arms 4, 6 at the proximal ends 8, 10 are fixed or secured together while other portions are pivotable relative to one another. In some embodiments, the arms 4, 6 are configured to move or pivot between open and closed positions about the connection 12. In some embodiments, the device 2 comprises a biasing mechanism (e.g., one or more elastic elements, springs, etc.) positioned between the arms 4, 6 and configured to operate in conjunction with the connection 12. For example, as illustrated in
The space or distance between the two arms can vary depending on how much pressure or force a user applies to close, press or push together the two arms. In different embodiments, the width of the arms 4, 6 can be varied. For example, the arms 4, 6 can have a width of ½ inch, 1 inch, 1.5 inches, values in between or otherwise. Likewise, each arm can be of various lengths.
In some embodiments, as illustrated in
As illustrated in
In some embodiments, the power is used to heat hair contacting surfaces 26, 28 of the two arms 4, 6 that are configured to press and/or straighten a user's hair between the two surfaces when the arms 4, 6 are pressed together. Each arm 4, 6 has an opposing surface 26, 28 that face each other and extend along a portion of an underside of each arm in a longitudinal direction between the proximal 8, 10 and distal ends 14, 16. The surfaces 26, 28 are configured to be heated via a heating circuit and heating elements in thermal communication with the hair contacting surfaces 26, 28, connected to the power source (described in more detail below). The heated surfaces 26, 28 are generally aligned in some embodiments and can abut or contact each other when the device 2 is moved into a closed position by the user, such as the positions illustrated in
In some embodiments, the surfaces 26, 28 are formed as part of plate members 54 and 56 (e.g., optional heating members) respectively as shown in
In other embodiments, one or both surfaces 26, 28 can include surface features. These features can include teeth, blades, blade shaped tines, grooves, ridges, projections or other protrusions that can project out from surfaces 26 and/or 28. In some embodiments, the surfaces 26, 28 do not include spiked-shaped teeth. These features can be heated as a result of the surface they project from being heated. In some embodiments, the features are heated directly. For example, the surfaces 26, 28 can be connected in thermal communication with heating electric elements. In some embodiments, the surfaces 26, 28 can be made from thermally conductive materials, such as aluminum, steel, ceramic, or other materials.
In some embodiments, such as that illustrated in
In some embodiments, the blades 30 and/or surfaces 26, 28 can extend to the edge or border of the lateral sides of each respective arm 4, 6. In some embodiments, the blades 30 and/or surfaces 26, 28 extend past or overlap a portion of the first and second lateral sides 64, 66 of the arms 4, 6 as shown in
Each blade can be configured such that they form a substantially solid and continuous material or protrusion extending across the width of one or both surfaces 26, 28. In some embodiments, the top of the blades 30 are configured to contact or abut the top of the opposing surface of the opposite arm when the arms 4, 6 of the device are biased together into a substantially closed position.
The plurality of rows of blades 30 are aligned such that individual rows are positioned adjacent to each other, one row in back of or in front of another, such that they form a series of blades longitudinally along the surface of an arm without any spike shaped disposed between the blades 30. As illustrated in an embodiment of the blades 30 in
In some embodiments, the arms 4, 6, surfaces 26, 28 and plurality of rows of blades 30 can be configured into different shapes such as flat, rectangular, circular, semi-circular, arc, convex and concave. The rows of blades 30 can be parallel to each other and closely spaced. As illustrated in
As illustrated in
In other embodiments, as illustrated in
With reference to
In some embodiments, the device 2 can also comprise rows of protrusions or blades 48 on an outer surface of the first arm 4 facing away from the surface 26 with the blades 30. These protrusions 48 can facilitate or improve the passing of the hair through the device 2. In some embodiments, these protrusions 48 can assist in pressing or straightening the hair. In some embodiments, the protrusions 48 can assist in curling the hair after it is passed through the heated blades.
In some embodiments, the straightening device 2 can include a tab, button, knob or switch 20 located on either the first or second arm to turn the device 2 on and off. As illustrated, a user can push or slide the switch 20 or tab to a first position to turn the device on or to a second position to turn the device off. Indicators can depict “on” and “off” to show a user which direction or position to slide the tab or button to turn the device on or off. In other embodiments, a button can be used to power on or off the device. For example, a user can simply press a button once to turn the device on and press it again to turn it off. Additionally, an indicator such as a light source 24 can be positioned on a surface of one of the arms of the device 2 and connected to the switch 20 so as to indicate whether the device is on or off. For example, the light source 24 can emit light when a user has turned or powered on the device 2. A light source, in some embodiments, can also indicate a specific temperature setting as discussed below.
In other embodiments, as illustrated in
In some embodiments, a first temperature setting can be lower than a second, third and/or more temperature settings. The first temperature setting in some embodiments can be lower than what is optimum for straightening hair or thicker, coarser hair while the second and third temperature settings can be higher than the first temperature setting and at a more optimal temperature for straightening hair. For example, in one embodiment, the “pretreat” temperature setting at 240 degrees Fahrenheit may not actually be high enough to straighten some types of hair. However, a user may wish to first heat hair at this temperature setting prior to using the other higher settings, “relaxed” and “natural.” Heating the hair at the lower temperature “pretreat” setting prior to straightening with the higher temperature settings can lead to improved straightening overall. The heating device 2 can have more than or less than three different temperature settings.
In some embodiments, the tab 22 can also comprise a light source 62. Depending on which indicator 58 and 60 the light source 62 is positioned adjacent to, a user can see or know which temperature setting the device 2 is set to.
In some embodiments, the arms 4, 6 can comprise fins, channels, or recesses 50 in the distal ends 14, 16 as illustrated in FIGS. 1 and 11-12. In some embodiments, these channels 50 can facilitate the cooling or removal of heat away from the surfaces 26, 28 when the device is powered off.
As noted above, the device 2 can include a heating circuit configured to provide electrical power to heating elements disposed in the device and configured to heat the hair contacting surfaces 26, 28. The heating elements can be any one of numerous commercially available heating elements, including those with integrated thermostat circuits. Additionally, the selector switch (
For example, such a circuit can include a power source providing electrical power to at least a first and second heat source to heat surfaces 26, 28 or plates of the first and second arm. The heating circuit can also include a switch allowing a user to turn the power on and off. The first and second heat sources can be any type of commercially available heat source that can be electrically connected to a power source. Examples include resistors, thermistors, variable resistors, or potentiometers. In certain embodiments, more than one resistor or heat source can be connected to the circuit such that different temperature settings can be realized or selected. In certain embodiments, a potentiometer or variable resistor can be used allowing a user to vary the resistance level and thus the temperature of the heat source. In some embodiments, the heat source can be connected to heating coils.
Various heating circuit layouts can be used with switches, thermostats, and heat sources in parallel and/or in series such that the device 2 allows a user to select different temperatures to heat the plates, surfaces, or surface features of the device 2. In some embodiments, a single heat source can be used to heat the surfaces, plates, or surface features. In other embodiments, more than one heat source can be used or connected to the circuit. In some embodiments, one heating circuit is used to activate a heat source or sources to heat the surfaces or features of the device for each respective temperature setting. In other embodiments, more than one heating circuit is used to activate a heat source or sources to heat the surfaces or features for the device for each respective temperature setting.
One embodiment of a method of straightening hair using the device 2 includes pressing the arms 4, 6 together, for example, in the direction of arrow C (
In some embodiments, a hair styling or heating oil, gel, or liquid can be used in conjunction with the device 2 in order to facilitate the straightening of hair. This oil can be applied to the surface or plates of the device 2 or to the hair directly prior to using the device.
