Description
FIELD OF THE DISCLOSURE

The present disclosure relates to the field of hairdressing. More specifically, the present disclosure is directed toward a curling rod device and hair curling technique used for the formation of spiral curls/coils/ringlets for all hair textures, with or without heat.


BACKGROUND

Generally speaking, a hair roller or hair curler is a small tube that is rolled into a person's hair in order to curl it, or to straighten curly hair, making a new hairstyle. The diameter of a roller varies from approximately 0.8 inches (20 mm) to 1.5 inches (38 mm). A hot roller or hot curler is designed to be heated in an electric chamber before one rolls it into the hair. A hair dryer heats the hair after the rolls are in place. When the hair is heated, the rollers strain and break the hydrogen bonds of each hair's cortex, which causes the hair to curl. The hydrogen bonds reform after the hair is moistened. Alternatively, hair spray can temporarily fix curled hair in place.


There are many hair curling devices available for the purpose of creating heatless spiral curls. However, the instant disclosure recognizes the challenge in the ability to easily and effectively secure hair tresses to such known devise. The majority of existing curl rods lack ease of use, hence time spent in the curling process is a big disadvantage. As an example, some existing curl rods use a form of rubber straps extending from one end of the rod and is stretched over the wound hair tress to a fastening socket at the other end in order to hold the curl in place on the rod. This is not always easy to achieve unless one is a skilled hair dresser. The tip of hair tresses tends to slip out from the securing rubber straps and ruin the curl formation process. A great deal of devices require excess hair manipulation or pulling of hair tresses when attempting to effectively secure the curl on the rod. Some hair textures require excess re-moistening and/or chemical products in order to effectively hold looped curls in place and achieve the desired spiral curl. Clearly, there is a need and/or desire to provide a curling rod device and/or method of use thereof that is easier to use.


In addition, the instant disclosure recognizes the cumbersome nature or size of most existing curl rods and discomfort in wearing such large curling rods. As a result, there is clearly a need to provide a curling rod device that is less cumbersome and more comfortable to wear.


Furthermore, the instant disclosure recognizes the dangers of using heated curling rods, especially when used by children. Accordingly, there is clearly a need to provide a curling rod device that is safe to use, especially with children, and does not require heat.


The instant disclosure may be designed to address at least certain aspects of the problems or needs discussed above by providing a hair curling rod device for creating tight spiral curls for all hair textures, with or without the use of heat.

In another aspect, the instant disclosure embraces hair curling rod device 10 in any embodiment and/or combination of embodiments shown and/or described herein.


Referring now to FIG. 9, in another aspect, the instant disclosure embraces method 200 of curling hair without heat. Method 200 of curling hair without heat may generally include utilizing hair curling rod device 10 in any embodiment and/or combination of embodiments shown and/or described herein. As such, method 100 of curling hair without heat generally includes step 202 of providing hair curling rod device 10 in any embodiment and/or combination of embodiments shown and/or described herein. With the provided hair curling rod device 10, method 200 of curling hair without heat further includes the steps of: step 204 of spreading top member 14 from bottom member 20, like via ones fingers, as shown in FIG. 8; step 206 of wrapping the hair around the bottom member (like as shown in FIGS. 5-7); and step 208 of closing top member 14 onto bottom member 20 thereby clamping down onto the hair wrapped around bottom member 20 and applying pressure on the hair wrapped around bottom member 20 via flat bottom side 18. Whereby, the hair wrapped around the bottom member 20 is curled, spiraled, or ringleted without the need for heat.


Still referring to FIG. 9, in select possibly preferred embodiments of method 200 of curling hair without heat, step 206 of wrapping the hair around bottom member 20 may include step 210 of starting from a scalp and wrapping the hair around bottom member 20 at first end 26, and step 212 of wrapping the hair around bottom member 20 in a spiral configuration toward second end 36.


Still referring to FIG. 9, in other select possibly preferred embodiments of method 200 of curling hair without heat, step 208 of closing top member 14 onto bottom member 20 may include step 214 of locking top member 14 to bottom member 20 by sliding locking cap 62 with locking hole 70 onto upward angled portion 38 of bottom member 20 and around top member 14 thereby locking top member 14 to bottom member 20.


In use, hair tresses are arranged to be wrapped in a spiral of multiple loops around the lower cylindrical sleeve 50 of bottom member 20 while flat bottom side 18 of top member 14 clamps down on the spirally wound/wrapped tresses to prevent shifting, thus effectively securing hair on bottom member 20. Hair tresses are wound around cylindrical sleeve 50 of bottom member 20 at first end 26 starting from the scalp, moving along the length of bottom member 20, to the second end 36 where the hair tresses are clamped in place. The clamping action on the spirally wrapped tresses applies pressure needed to form/set curl with or without heat. Soft locking cap 62 may be fastened onto second end 36 of hair curling rod device 10 to hold top member 14 in a closed position on bottom member 20, further securing hair tresses in place in case of disturbing activities such as workout, sleep etc. Soft locking cap 62 may consist of soft, non-porous foam 72 with tiny venting holes 74 which may enable venting/drying of hair wherein, when water/moisturizer/curl setting product is used. Soft locking cap 62, along with protective cover member 60 may prevent the metal material 48 of hair curling rod device 10 from being in contact with the scalp, which may assure maximum comfort to the wearer, as well as comfortable night's sleep if desired to be worn overnight. Second end 36 of hair curling rod device 10 is uneven, or top member 14 is disproportionate in length with bottom member 20, which provide the ease of opening top member 14 from bottom member 20 and inserting hair tresses. As shown in FIG. 8, top member 14 is spread from bottom member 20 using 2-5 fingers, where sectioned hair tresses are slipped between top member 14 and bottom member 20 and wound in a circular/spiral motion along the length of bottom member 20, from first end 26 toward second end 36 of hair curling rod device 10 (see FIGS. 5-7). Once hair is wound around bottom member 20, the finger grip is released, enabling top member 14 to clasp down on wound hair. Soft locking cap 62 may then be slipped on to complete the process.


Hair curling rod device 10 can be designed and configured with varying rod lengths and cylindrical sleeve tube sizes to accommodate different hair lengths and desired curls.


Hair curling rod device 10 may provide crossover between classic hair rollers, perm rods, and curl rod devices, that can be used on human or synthetic hair textures (wigs, extensions, doll hair etc.).


In sum, the present disclosure is directed to an innovative heatless hair curling rod device 10 that may be designed and configured to create tight spiral curls for all hair textures, with or without the use of heat. Hair rod curling device 10 may provide a construction/shape of a devise that is arranged to apply pressure to hair tresses wrapped around a soft smooth rod member/disposed in between, when the rod is in clamped/closed position, thereby causing the tresses to form curls without the need for an application of heat or use of excess hair curl setting mediums (wax, gel, foam, mousse). Optionally, water/curl setting medium may be applied to spirally wrapped tresses on rod afterwards, to facilitate the formation of curls. A great feature of the present disclosure is its ability to reduce the time spent achieving desired curls. The reduced time spent correlates with the technique used to wound hair tresses around hair rod and method used to quickly secure hair tresses to rod.


The disclosed device and method may be designed to allow curls to be spirally wound, where they are not wound on top of each other, like the classic hair rollers. Classic hair rollers described as such usually produce short, round, puffy/frizzy curls or waves. With the present disclosure, hair tresses are wound adjacently to each other in a spiral manner to achieve stretched-out/elongated defined curls (see FIG. 7), or short tight spiral curls (see FIGS. 5-6). Curls may be achieved on dry hair or with a slight spritz of water, moisturizer, or curl setting medium. This may be particularly useful for individuals that do not wash hair daily/use excess curl setting mediums/use hot tools or dryer. Water/curl setting medium may be applied after hair tresses are secured on the rod.


Another great feature of the present disclosure may be its ability to produce strong clamping action on the wound hair tresses, thereby securing the curl in place. Soft locking cap 62 may be fastened on second end 36 of hair curling rod device 10, slightly overlapping a portion of clamped hair for an ultimate hold. The clamping action/pressure of curl rod on hair tresses promotes its ability to be used without heat or application of excessive curl setting products, thereby avoiding heat damage or excessive hair manipulation/pulling force/damage. Hair curling rod device 10 may efficiently permit the clamping of hair tress for sufficient time necessary to set spiral curls.


Another feature of the present disclosure is its ability to achieve tight spiral/corkscrew-like curls on dry or slightly moistened/spritzed hair with little or no manipulations. Some hair textures may require excess re-moistening and/or chemical products in order to effectively hold looped curls in place and achieve the perfect spiral curl. The clamping action of hair curling rod device 10 may eliminate unnecessary use of hair products and forceful manipulation. Less manipulation may lead to less breakage and may promote retention of hair length over time.


Another feature of the disclosed hair curling rod device 10 may be the comfort or wearability. Most curling devices are cumbersome in size or made of hard plastic. This present disclosure is compact, and the metal core is surrounded by soft silicone. A protective soft foam locking cap 62 may be fastened/affixed onto the tip of device as well as protective cover portion 60 used at the opposite u-bend end to prevent the metal core rubbing/being in contact with the scalp. This may ensure maximum comfort for prolonged wear.


Another feature of the disclosed hair curling rod device 10 may be its versatility. The ability of the disclosed device to be use on extremely short hair due to clamping action may be revolutionary. Most curl rod devices require longer hair tresses in order to work properly. The disclosure may provide a breakthrough for all hair types, especially those with little to no natural curl pattern.
