CROSS REFERENCE TO RELATED APPLICATIONS

[0001 ] This application claims priority to U.S. Non-Provisional Application Number 17/840,530, filed June 14, 2022, the entire disclosures of which are incorporated herein by reference.

TECHNICAL FIELD

[0002] The present disclosure relates generally to a hair styling apparatus.

BACKGROUND

[0003] Hair styling is a very important part of an individual’s fashion. Different occasions require different looks, and hair style is an integral feature of a person’s self-image. Thus, quite often, a person is expected to change their hairstyle to go along with the outfit and/or the occasion. It may be desirable to straighten one’s hair for a certain occasion, while other situations warrant a big wave.

[0004] As a consequence to the demands of hair styling by individuals, hair styling tools and apparatus play a very important role in an individual's lives. A typical hair styling apparatus consists of a circuit and a heater to heat ha ir strands at a predetermined temperature range. Heated hair strands soften, which allows them to be suitably adjusted to give a desired shape. Most common heaters available in the arket are cylindrical-shaped (for curling hair) and fiat-shaped (for straightening hair).

[0005] T raditional flat iron hair tools generate high temperatures, which increases the chances of hair damage. Additionally, using flat irons with jaw-shaped clamps for hair straightening breaks down hair strands, making them brittle and forming split-ends. Further, current hair dressing procedures include several complicated steps that are both time-consuming and harmful to hair strands. Further, long and repeated use of such products results in damage to the scalp, which in turn lead to further unpleasant consequences such as skin irritation, hair loss, skin-burn, and so on.

[0006] Therefore, there is a need for a hair styling apparatus that enables hair styling in a short period of time without affecting or damaging hair in any way.

[0021] Referring to Fig. 1, a hair tool 10 includes heating plates 12 that are curved to appear like a U shape both laterally and longitudinally. Also, as best illustrated by Fig. 4, the heating plates 12 further include a top plate 50 and a bottom plate 52 beneath the top plate 50 concentrically arranged to each other when the hair tool 10 is in a closed position.

[0022] Fig. 2A is a front view of the top plate 50 having multiple concentric layers, and Fig. 2B is a front view of the bottom plate 52 having multiple concentric layers. The heating plates 12 are typically made of a suitable material capable of handling high temperatures, such as for example, but not limited to, ceramic, titanium, alloys of titanium. Teflon, other metals, and the like, and combinations thereof. In one embodiment, an inner side of the heat plate is provided with a metal, preferably titanium. The heating plates 12 are uncovered (i.e., for both the top plate 50 and the bottom plate 52). This allows the heat to penetrate through the hair more evenly and more quickly. This feature works especially well for curling hair. Also, the lack of covering for the heating plates 12 also help maintain the temperature at a certain level, without possibility of overheating, which may cause heat damage to the hair. Further the heating plates 12 have a free end 14 where the gap between the concentrically arranged heating plates 12 is controllable. Hair io be styled is generally placed or passed through the gap between the concentrically arranged heating plates 12 at the free end 14, typically when the plates are in a heated state that will allow styling of the hair as needed by a user.

[0023] Typical means for heating the heating plate involve use of a suitable heater (not shown). In the embodiment, the heater may include Phase Transfer Coefficient (PTC) based heaters, metal-ceramic heaters (MCH), heater based on mica sheet heater, a rope heater, and the like, and combinations thereof. The apparatus further includes a temperature sensor (not shown). Exemplary temperature sensors include negative temperature coefficient (NTC) thermistors or a diode with an aluminum piece. Temperature sensors are used for controlling a preset. The temperature values may be predetermined in a temperature control circuit (not shown), which allows users to set different temperatures.

[0024] In an embodiment, there may be three temperature control settings. Each setting can be seen on a display 60 along with the temperature and hair type settings. The temperature control settings allow the user to select the necessary setting for a specific ha ir type, and prevents heat damage to the hair. Setting 1 will be for fine hair with a temperature setting of 180 degrees Fahrenheit. Setting 2 will be for thick hair with a temperature setting of 200 degrees Fahrenheit. Setting 3 will be for course hair with a temperature seting of 350 degrees Fahrenheit.

[0025] In some embodiments, the hair styling apparatus may also include a display 60, as shown in Fig. 3. The display 60 may be configured to display temperature to allow the user to see the temperature for the necessary for the heat setting.

[1)026] Returning to Fig. 1, the gap between tire concentrically arranged heating plates 12 is controlled by a lever 16. The gap size may be adjusted by pushing or pulling the lever 16, and then locking the lever 16 at a certain point that corresponds to the predetermined gap size. Examples of locking means may include providing suitable ridges (not shown) whose position corresponds to the appropriate gap size, wherein a protrusion on the lever is allowed to rest on tire appropriate ridge. Alternately, a gear-like structure may be provided to achieve the same function. Other ways io use the lever 16 to control gap size may be encompassed within the scope of the disclosure. In the embodiment shown in Fig. 1, the lever 16 is provided on the top end of the hair styling apparatus 10.

[0027] Distal from the free end 14 of the heating plates 12 is an atached end 15 that is connected to a connecting handle 18, through which the rest of the hair styling apparatus 10 is connected to the heating plates 12. In an embodiment, the handie 18 may have finger grip indentations that allow the user to better hold and grip the hair styling apparatus, so that the hair styling apparatus does not easily slip from the user’s hand during operation

[0028] In one embodiment, the heating plates 12 are configured to extend outwardly from the connecting handle 18 in a longitudinally curved (i.e., curvilinear across the length of the hair styling apparatus 10 and/or the heating plates 12) or obliquely downward direction relative to the display 60 on the top of the hair styling apparatus, which facilitates ergonomic gripping and holding by the user, and offering better control of the hair styling apparatus while in use. Additionally, the U-shaped curve of the heating plates 12 across the transverse axis of the hair styling apparatus 10 (across a width of the hair styling apparatus 10 and/or the heating plates 12 perpendicular to the longitudinal axis of the hair styling apparatus 10 and/or the heating plates) towards the hair and head of the customer conducts neat more quickly and spreads heat across the hair more evenly than the flat shaped plates. Further, the smooth rounded edges and sides of the plates help shape the hair for the desired style whether it's for straightening, cur hug or waving.

[0029] It is noted that sizes of the heating plates 12 may vary and may be interchanged to accommodate for various lengths of hair. For example, the smaller size apparatus will accommodate the shorter hair lengths, while the larger sizes apparatus will accommodate the longer hair. In more detail, a l"X5”-sized heating plates 12 may accommodate extreme short hair, a 2”X6"-sized heating plates 12 may be preferable for short hair, a 3”X6.5”-sized heating plates 12 may be preferable for medium length hair, and a 4"x5" and 5"X7.5"-sized heating plates 12 may work best for long hair. [0030] The hair styling apparatus further includes a gripping portion 20 at a distal end of the hair styling apparatus away from the heating plates 12. The gripping portion 20 may include finger indents to enhance gripping by the user. Further, the gripping portion may be made of a suitable material such as a rubber that also enhances gripping by a user. Also, the gripping portion may be made in such a way (e.g., with insulating materials such as plastic, rubber, composites, etc. J that it is insulated from heat. This would then allow for the user to be protected by the heat emanating from the heating plates 12.

[0031] The hair styling apparatus 10 further includes a stand 22 that is configured such that the apparatus can be supported while resting on a surface such as a tabletop or a floor when not in use. Fig. 1 shows on embodiment of the stand 22 wherein it is configured to be perpendicular to a bottom plate 52 atached to the connecting handle 18 that will support the tool while not in use.

[0032] The hair styling apparatus then includes a power module 26 that allows for heating of the heating plate. The power module 26 may include a DC power source such as a battery, or may be configured to plug into an AC power source. Battery, when provided, may be of a suitable voltage and wattage as required by the apparatus. Further, bateries may be rechargeable, and may also be conveniently removably provided that will enable removal for external recharging, facile replacement, and so on. Also, battery compartment may be configured to receive a plurality of batteries to achieve the required voltage to power the apparatus.

[0033] In some embodiments, the hair styling apparatus 10 may further include tire display 60 as shown in Fig. 3 to display any number of messages to the user. The display 60 may be in the form of digits, alphabets, or alphanumeric codes, each of which corresponds to a specific message to inform the user of the apparatus’ current status. For example, a message H may be ready to indicate the apparatus is still heating, while R may be used to indicate the apparatus is ready for use, and the like. Typically, a manual is provided to go with the apparatus, wherein the manual lists the codes and their meanings for the user’s convenience. A larger display 60 may be used to display more complete words and sentences to convey the status to the user.

[0034] Fig. 4 is a perspective view of the hair styling apparatus 10 that shows the top heating plates 50 and includes a botom plate 52 connected to the handle 18. Fig. 5 is a front view of die hair styling apparatus. [0035] The present disclosure relates io a hair styling apparatus 10 that is versatile to handle any kind of styling (e.g., for straightening, curling, or waving hair). The U- shaped curves of the heating plates 12 allows for efficient heating c>f the hair strands by allowing heat to transfer through the hair more quickly than the traditional hair sty ling apparatus. More efficient heat transfer results in hair being exposed to heat for a lesser time, which in turn prevents breakage of hair.

[0036] Also, an LED (indication light) as a safety feature is disposed on the hair styling apparatus 10. Therefore, whenever the tool is off, there is no light indication, when the device is on, lire indication light will be green. Also, the hair styling apparatus will automatically shut-off when the device is not continuously in use for the last 30 minutes, which prevents the hair styling apparatus 10 from becoming a fire hazard or from needlessly consume electricity.

[0037] Further, the hair styling apparatus 10 as disclosed is provided with a stand 22 perpendicular to the bottom plate 52 attached to the connecting handle 18, which supports the hair styling apparatus 10 while not in use. The stand 22 effectively prevents the occurrence of skin burns while using the device in ease of immature use.

[0038] Because of the unique design of the hair styling apparatus 10 as disclosed, there is no need to change the plates from the connecting rod 18 for different purposes. That is, the hair styling apparatus 10 may be used to curl, wave, and straighten hair.
