FIELD OF THE INVENTION
The present invention relates to a hair styling device. More particularly, the instant invention relates to a hair styling device containing two configurations of stable mechanical shapes, such that the hair styling device is capable of physical transformation to hold and retain a bundle of received hair in a desired style.
BACKGROUND OF THE INVENTION
U.S. Pat. No. 6,116,251 (hereafter '251 patent), which is entitled “Spring Strip Hair Clip”, comprises a carbon spring steel strip 1001 and an elastic strip 1002, as shown in FIG. 1A. The elastic strip 1002 is to hold hair against the carbon spring steel strip 1001 when the carbon spring steel strip 1001 coils into a closed position. The elastic strip 1002 can be stretched away from the carbon spring steel strip 1001 to allow space for hair to be placed between the carbon spring steel strip 1001 and the elastic strip 1002. However, the elastic strip 1002 can also extend too far from the carbon spring steel strip 1001 and not remain in alignment when hair weighs the device down, such that the Spring Strip Hair Clip does not hold the entered hair securely while rolling it up and snapping it into a top knot, low bun or updo hair style.
In another embodiment described in the '251 patent, wherein a flexible attachment member 1003 connects an end of the first strip to an end of the second strip as shown in FIG. 1B, the problem is that the flexible attachment of the two strips allows movement of the strips relative to each other in all three axis of motion making the securing of the bundle of hair while maintaining the alignment of the two strips cumbersome for the user.
U.S. Pat. No. 8,757,176 B2 (i.e. hereafter '176 patent), which is entitled “Hair Accessory and Method Styling Hair” comprises two pieces of metallic members 1004 and 1005 as shown in FIG. 1C. Those two pieces of metallic members 1004 and 1005 are fixedly attached to each other at one longitudinal end via a rivet 1006, and are free and unattached to each other at the other longitudinal end for receiving a bundle of hair from the opening 1007. To use the hair accessory, the two pieces of metallic members 1004 and 1005 must be lined up and manually closed at the unattached end after hair inserted for styling. It is cumbersome to insert hair, manually close and then compel both bistable strips to simultaneously snap to their second stable state. Moreover, hair might become disordered when finally inserted and positioned.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
A hair styling device that easily and securely maintains a wearer's hair in a decorative and/or functional configuration is provided. The presently disclosed technology comprises the hair styling device for receiving and retaining a bundle of hair into a desired style, like a bun, ponytail or other.
The hair styling device according to the present invention includes a base member, a holding member and an attaching member, which will be respectively described hereinafter by way of a variety of embodiments and examples with reference to the accompanying drawings. Referring to FIG. 2A and FIG. 2B, a thin strip 10 is used as an embodiment of the base member, and has two mechanical shapes stabilized by different curvature axes. A first stable state where the base member 10 is a linear structure with a curved ridge 105 extending in a longitudinal direction 106, such that the base member 10 has a concave surface 14, a convex surface 13 and two longitudinal ends 101 and 102. A second stable state where the base member has at least one wrap-around cylindrical structure coiled around lateral axis 107 where the curved ridge 105 disappears, as shown in FIG. 2C and FIG. 2D. The first stable state transforms into the second stable state when at least one point of pressures is applied on the convex surface 13 of the base member 10. The base member 10 can be reconfigured from the second stable state back to the first stable state by physically unraveling and straightening the base member 10. The base member 10 is made of any material with at least two stable physical states including one selected from the group consisting of engineering materials, steel, alloy, iron, aluminum, tin, foam skin, plastic and carbon fiber and similar.
The base member 10 may be of varying thickness, width and length to both adapt to the specific material of which it is made and to accommodate different volumes or textures of hair.
The holding member 20 is preferably pliable. When in use with the base member 10 in the first stable state, the holding member 20 has a pair of ends 201 and 202. In this position, the holding member 20 is opposed to the concave surface 14 of the base member 10 and is capable of physical transformation to accommodate the transition of the base member 10 to, and from, the first and the second stable states. In an embodiment, the material of the holding member 20 may, but not necessarily, be non-metallic, for example, fabric (e.g. mesh, legging material, vinyl, nylon and spandex), silicone, plastic, rubber, flannel woven, plush, sequin, velvet, silk, polyester, nylon, satin, PVC prismatic reflective sheet, vinyl, polyethylene, polythene, leather and other similar material.
An embodiment of the attaching member 30 is schematically illustrated in FIG. 3A, which includes a first part 3A and a second part 3B wherein the first part 3A is directly formed on or mounted to the base member 10 at two opposite ends 101 and 102 of the base member 10, respectively, and the second part 3B is directly formed on or mounted to the holding member 20 at two opposite ends 201 and 202 of the holding member 20, respectively. FIG. 3B schematically illustrates a partially enlarged view of the attaching member 30 disposed at one end of the base and holding member assembly, wherein the first part 3A includes a plurality of hook posts 3010 and the second part 3B includes a plurality of loop posts 3020. The first part 3A and the second part 3B may be fixed onto the base member 10 and the holding member 20 by way of glue, press or any other laminating means, or integrally formed therewith. In an alternative embodiment, the first part 3A includes a magnetic set 311 of a first polarity, e.g. N pole, and the second part 3B includes a magnetic set 312 of a second polarity, e.g. S pole, attractive to the magnetic set of the first polarity, as illustrated in FIG. 3C. Each the magnetic sets 311 and 312 may include one or more magnetic pieces, and is mounted to the base member 10 and holding member 20 in selected ways suitable for the materials of the base member 10 and holding member 20. It is to be noted that, if the base member 10 is made of a metallic material or includes a metallic portion there, the magnetic set 311 can be omitted, and the magnetic set 312 can be directly coupled to the metallic base member 10.
FIG. 3D schematically exemplifies how the first part 3A and the second part 3B are coupled to the base member 10 and holding member 20 if the first part 3A and the second part 3B of the attaching member 30 cannot be directly formed on the base member 10 and the holding member 20.
In this embodiment, the first part 3A includes a first sleeve 301 and a second sleeve 302 put on the first end 101 and second end 102 of the base member 10, and the second part 3B includes a third sleeve 303 and a fourth sleeve 304 put on the first end 201 and second end 202 of the holding member 20, respectively. By combining the first sleeve 301 with the third sleeve 303 and combining the second sleeve 302 and the fourth sleeve 304, the base member 10 and the holding member 20 can be integrated with jointed longitudinal ends. In this embodiment, the first part 3A further includes a plurality of mini-posts which have a first kind of curved ends, e.g. hook posts 3010, formed on the first sleeve 301 and the second sleeve 302, and the second part 3B includes a plurality of mini-posts which have a second kind of curved ends, e.g. loop posts 3020, formed on the third sleeve 303 and the fourth sleeve 304, wherein the hook posts 3010 and the loop posts 3020 are engageable with each other when encountering, and detachable from each other when opposite-directional forces are exerted to separate them. With the engagement of the hook posts 3010 and the loop posts 3020, ends 201 and 202 of the holding member 20 can be connected with ends 101 and 102 of the base member 10, respectively, to form a closed loop. Hair can be inserted into a space 97 formed inside of the loop and rolled up to be styled. Since the hook posts 3010 and the loop posts 3020 are repeatably engageable with and detachable from each other, hair can be placed onto one of the base member 10 and holding member 20 first, and the other of the base member 10 and holding member 20 is stacked onto the base member 10 and holding member 20 with hair to have the first part 3A and the second part 3B engage with each other so as to complete the assembly. Afterwards, hair can be rolled up as desired. Likewise, the hook posts 3010 and the loop posts 3020 may be replaced with magnetic sets 311 and 312 with different polarities, which attract each other when encountering, and the magnetic set 311 can be omitted if the base member is made of a metallic material or includes a metallic portion to couple to the magnetic set 311.
In the above embodiments, the hook posts 3010 and the loop posts 3020 face each other to be engaged when assembling. In other embodiments as illustrated in FIGS. 4A, 4B and 4C, which have basic structures similar to those shown in FIGS. 3A, 3B and 3D, respectively, the hook posts 3010 are formed on the convex surface 13 of the base member 10, and the loop posts 3020 formed on the holding member 20 face the convex surface 13 of the base member 10. By having the holding member 20 longer than the base member 10 and wraps over the longitudinal ends 101 and 102 of the base member 10, the first part 3A and the second part 3B may engage with each other at the convex surface 13 of the base member 10. In this way, the space 97 is maximized as the entire longitudinal length of the base member 10 is available to hold hair. Likewise, the hook posts 3010 and the loop posts 3020 may be replaced with magnetic sets 311 and 312 with different polarities, which attract each other when encountering, and the magnetic set 311 can be omitted if the base member is made of a metallic material or includes a metallic portion to couple to the magnetic set 311.
Please refer to FIG. 5A and FIG. 5B. FIG. 5A is a schematic diagram which illustrates a hair styling device according to a further embodiment of the present invention; and FIG. 5B is a side view schematically illustrating the hair styling device of FIG. 5A, which has a securing member for securing the second stable state where the base member has a wrap-around cylindrical structure coiled around lateral axis where the curved ridge disappears. In this embodiment, a plurality of hook posts 3030 are provided onto the convex surface 13 of the base member 10, and a plurality of loop posts 3040 are provided onto the surface of the holding member 20 facing away from the base member 10, collaboratively serving as a securing member. With the hook posts 3030 and the loop posts 3040, a hook-and-loop fastening function can be performed for securing the second stable state where the base member has a wrap-around cylindrical structure coiled around lateral axis where the curved ridge disappears. It is understood by those skilled in the art, the hook posts 3030 and loop posts 3040 may be exchanged, or alternatively, hybridized or arranged in patches, as long as the hook-and-loop fastening purpose can be achieved. Furthermore, the hook-and-loop fastener is merely an example of the securing member, and may be replaced with other engaging/disengaging means, e.g. magnetic sets with different polarities.
Likewise, as shown in FIG. 6A and FIG. 6B, by properly arranging hook/loop posts 3030 and 3040 on the sleeves 301, 302, 303 and 304, the second stable state, where the base member 10 has a wrap-around cylindrical structure coiled around lateral axis where the curved ridge disappears, may be secured with the engagement of the hook/loop posts 3030 and 3040. Another embodiment schematically illustrated in FIG. 6C differs from that schematically illustrated in FIG. 6A in that mini-posts provided on the sleeve 304 need to be different from those provided on the sleeve 303, e.g. hook posts 3040′ and loop posts 3040, so as to able to form two wrap-around cylindrical structures as schematically shown in FIG. 6D.
Similar discussion applies to the embodiment illustrated in FIG. 7A and FIG. 7B, which is modified from the embodiment illustrated in FIG. 5A, as well as the embodiment illustrated in FIGS. 8A and 8B, which is modified from the embodiment illustrated in FIG. 6. In these embodiments, a hook-and-loop fastener is also used as a securing member for securing the second stable state where the base member has the wrap-around cylindrical structure(s). Likewise, the hook-and-loop fastener is merely an example of the securing member, and may be replaced with other engaging/disengaging means, e.g. magnetic sets with different polarities.
Please refer to another embodiment of hair styling tool according to the present invention, as illustrated in FIG. 9A. In this embodiment, the attaching member includes a first part 5A and a second part 5B, wherein the first part 5A includes a supporting base 501 formed with mini-posts 5010 and attached onto the base member 10, and the second part 5B includes a supporting base 502 formed with mini-posts 5020 and attached onto the holding member 20. The supporting base 501 is wrapped around the base member 10, and the supporting base 502 is wrapped around the holding member 20. Mini-posts 5010 are distributed on the supporting base 501 not only at positions corresponding to the longitudinal ends 101 and 102 of the base member 10 as described above, but also in a middle portion 103 of the base member 10. Likewise, the mini-posts 5020 are distributed on the supporting base 502 not only at positions corresponding to the longitudinal ends 201 and 202 of the holding member 10 as described above, but also in a middle portion 203 of the holding member 20. The first part 5A and the second part 5B are fixed to each other by connecting the supporting base 501 and the supporting base 502 at the opposite ends 101 and 102 of the base member 10 and the opposite ends 201 and 202 of the holding member 20, thereby forming a closed loop, and hair can be inserted into the space 97 from an opening of the closed loop. The first part 5A and the second part 5B can be further fixed to each other with the mini-posts 5010 and 5020 to have the middle portion 103 of the base member 10 and the middle portion 203 of the holding member 20 coupled to each other. In this embodiment, the engagement of the mini-posts 5010 and 5020 further secures hair in the space 97 in a well-distributed state, so that hair can be evenly rolled up with the base member 10 and holding member 20 to have a better styling effect. In this embodiment, the mini-posts 5010 are hook posts, and the mini-posts 5020 are loop posts. Likewise, the hook-and-loop fastener is merely an example of the attaching member, and may be replaced with other engaging/disengaging means, e.g. magnetic sets with different polarities. Since the base member 10 and the holding member 20 has already been connected together at opposite ends, the mini-posts 5010 and the mini-posts 5020 do not need to be of different types for fastening the base member 10 with the holding member 20. Instead, the curved parts of the mini-posts can interact with hair so as to smooth hair when penetrating through hair. Therefore, the mini-posts 5010 and the mini-posts 5020 may be, for example, both loop posts or both hook posts. Alternatively, either the mini-posts 5010 in the middle portion 103 of the base member 10 or the mini-posts 5020 in the middle portion 203 of the holding member 20 may be omitted. Likewise, the magnetic set arranged on the holding member 20 can be omitted if the base member 10 is made of a metallic material or includes a metallic portion to couple to the magnetic set.
In an alternative embodiment, the supporting part 5A may be integrally formed with the base member 10 and/or the second part 5B may be integrally formed with the holding member 20. In other words, the loop posts 5010 are directly formed on the base member 10 without the supporting base 501, and/or the hook posts 5020 are directly formed on the holding member 20 without the supporting base 502.
In an alternative embodiment modified from the embodiment of FIG. 4C and the embodiment of FIG. 9A, which is schematically illustrated in FIG. 9B, the second sleeve 302 with hook posts 3010 and the fourth sleeve 304 with loop posts 3020 are omitted, and the corresponding ends 102 and 202 of the base member 10 and holding member 20 are jointed in another way instead of the hook-and-loop fastener manner. Further examples of the jointing ways between the base member 10 and holding member 20 can be referred to the parent U.S. patent application Ser. No. 15/842,873, contents of which are incorporated herein for reference. In this embodiment, the base member 10 and the holding member 20 may form a closed loop and hair is inserted into the space 97 from an opening of the closed loop, or the ends 101 and 201 of the base member 10 and holding member 20 can be opened to receive hair therefrom, and then closed with the hook posts 3010 and loop posts 3020. Likewise, the hook-and-loop fastener is merely an example of the attaching member, and may be replaced with other engaging/disengaging means, e.g. magnetic sets with different polarities.
FIG. 10A schematically illustrates another embodiment of hair styling tool according to the present invention. In this amendment, the attaching member includes a first part 6A and a second part 6B, wherein the first part 6A includes a supporting base 601 formed with a plurality of magnetic pieces 6010 attached onto the base member 10, and the second part 6B includes a supporting base 602 formed with a plurality of magnetic pieces 6020 attached onto the holding member 20. The supporting base 601 may be wrapped around the base member 10, and the supporting base 602 may be wrapped around the holding member 20. The base member 10 and the holding member 20 may be made of the same or different material. For example, the holding member 20 may also be made of metal, metallic material, plastic material or any other suitable material that has two stable states similar to the base member 10. In this embodiment, the base member 10 and the holding member 20 are connected to each other by longitudinal sides 104 and 204 thereof instead of or in addition to their longitudinal ends 101/102 and 201/202. More specifically, the supporting base 601 and the supporting base 602 are integrally formed as a single piece of material. An opening 99 is disposed between the supporting base 601 and the supporting base 602 for receiving therefrom hair, and the supporting base 602 can be folded to overlap with the supporting base 601 after hair is inserted from the opening 99. The magnetic pieces 6010 and the magnetic pieces 6020 are of different polarities and attract each other to stably clamp hair in the space between the base member 10 and the holding member 20. Afterwards, hair can be rolled up with the base member 10 and the holding member 20 to style hair. Alternatively, the magnetic pieces 6010 and the magnetic pieces 6020 may be replaced with hook posts and loop posts as mentioned above, which are coupled to each other to clamp hair therebetween.
FIG. 10B schematically illustrates an alternative embodiment of the hair styling tool according to the present invention, which is similar to and modified from the hair styling tool shown in FIG. 10A. In this embodiment, the base member 10 is made of a metallic material, and the supporting base 602 is used not only for disposing the magnetic pieces 6020 but also serving as the holding member. The supporting base 602 can be folded to overlap with the supporting base 601 before or after hair is inserted from the opening 99, and the magnetic pieces 6020 is coupled to the metallic base member 10 to stabilize the well-distributed hair before rolling up. Similar variations can be made as described with reference to FIG. 10A, and are not to be redundantly described herein.
In an alternative embodiment modified from the embodiment shown in FIG. 10A, the magnetic pieces 6010 and 6020 (or hook/loop posts) arranged at the longitudinal sides, i.e. arranged in parallel to the base member 10 and holding member 20, are omitted. In other words, magnetic pieces 6010 and 6020 (or hook/loop posts) are only disposed at longitudinal ends of the base member 10 and holding member 20. Meanwhile, the supporting base 601 and the supporting base 602 are connected to each other or integrally formed as a single piece of material with the opening 99 remained for passing therethough hair.
Further referring to a further embodiment illustrated in FIGS. 11A and 11B, which are modified from the embodiment illustrated in FIG. 9B. By properly arranging hook/loop posts 3040 and 3040′ on the holding member at opposite ends, the second stable state, where the base member 10 has a wrap-around cylindrical structure coiled around lateral axis where the curved ridge disappears, may be secured with the engagement of the hook/loop posts 3040 and 3040′. In this embodiment, the mini-posts 5010 and 5020 for interacting with hair to smooth hair when penetrating through hair may be both or either provided or omitted. The hook-and-loop fastener is merely an example of the securing member, and may be replaced with other engaging/disengaging means, e.g. magnetic sets with different polarities.
FIG. 12A illustrates a further embodiment of a hair styling device according to the present invention, and FIG. 12B schematically exemplifies the formation of the hair styling device of FIG. 12A. In this embodiment, a base member 10 is attached to or wrapped by an elongated holding member 20. The holding member 20 is folded to have one end thereof, which is disposed with mini-posts 3010, engage with mini-posts 3020 (partially shown) disposed at the other end of the holding member 20 and underlying the base member 10, thereby form a closed loop with none, one or both ends able to be opened for receiving hair therein. As described above, after hair is clamped into the space 97, the entire device can be wrapped around, and meanwhile, the mini-posts 3030 and 3040 engage with each other to secure the second stable state.
It is to be noted that in the above embodiments, the first part 3A/5A includes hook posts and the second part 3B/5B includes loop posts. Alternatively, the first part 3A/5A may include loop posts and the second part 3B/5B includes hook post. The first part 3A/5A and the second part 3B/5B may also have mixed hook and loop posts as long as they can be successfully engaged with each other. Moreover, the above-mentioned sleeves are only examples for attaching the hook and/or loop posts onto the base member and the holding member, and can be replaced with supporting sheets, which are, for example, glued, taped or sewn onto the base member and the holding member. The hook and/or loop posts can also be provided onto the base member and the holding member in any other proper way with or without the supporting bases.
For further improving hair-smoothing and hair-styling performance, it is preferred that the hair styling device can release heat to hair. For achieving this purpose, the base member 10 is preferably made of a heat-conducting material, which retains heat when heated by an external heat source, e.g. hair dryer, microwave, oven, electricity, steam, sun, induction, or any other suitable heating source, and dissipates heat to hair inserted between the base member and the holding member. The material that is suitable to be used to form the base member 10 includes, for example, a metal or a metallic material.
In an alternative embodiment, the hair styling device is similar to any of the embodiments described above (taking the embodiment as illustrated in FIG. 3A as an example herein) and further comprises a heater material 200 disposed adjacent to the base member 10 for dissipating heat to hair when hair is inserted between the base member 10 and the holding member 20. The heater material 200 can spontaneously dissipate heat and/or be heated after being placed in the hair styling device, as illustrated in FIG. 13A or FIG. 13B. In the embodiment shown in FIG. 13A, the heater material 200 is disposed on the surface 14 of the base member 10, facing the holding member 20; and in the embodiment shown in FIG. 13B, the heater material 200 is disposed on the surface 13 of the base member 10, away from the holding member 20. To avoid overheat, a heat-buffering material, e.g. silicon, may be sleeved around the base member 10 with the heater material 200. The heater material 200, for example, may be a sheet of ceramic, copper, aluminum, titanium, foil, iron, steel, carbon fiber, fiber glass, ceramic, clay, magnesium or metallic material, or a heating bag. The materials applicable in a reflective foil technology, such as heat-reflective aluminum film coated fiber glass fabric or cloth, a ceramic fiber paper, PTFE (Polytetrafluoroethylene) rope with graphite coating, weld backing tape, etc., may also be used in the invention as the heater material 200.
In a further embodiment as illustrated in FIG. 14, the hair smoothing device is similar to any of the embodiments described above (taking the embodiment as illustrated in FIG. 3A as an example herein) and the base member 10 further comprises a gripping portion 98 to improve the positioning and retention of hair. Materials with properties suitable to improve the positioning and holding of hair, such as silicone, rubber, synthetic wig or anti-slippage material may be affixed, or otherwise added, to either, or both, the base member or holding member. The holding member further comprises a gripping portion 99 to improve the positioning and retention of hair. Materials with properties suitable to improve the positioning and holding of hair, such as silicone, rubber, synthetic wig or anti-slippage material may be affixed, or otherwise added, to either, or both, the base member 10 or holding member 20. The gripping portion 98 and the gripping portion 99 may coexist with the hook/loop posts in the middle portions 103 and 203 of the base member 10 and holding member 20.
Decorative materials such as fabric, leather, flannel woven, plush, sequin, velvet, silk, polyester, Polyester, nylon, satin, PVC prismatic reflective sheet, vinyl, polyethylene, polythene or other may be added to either the base member 10 or the holding member 20 for aesthetic considerations to improve the visual attractiveness for the user or ‘feel’ of the device when touched by the user, while the hook/loop posts are exposed to be in contact with hair.
There are number of ways to use the hair styling device. Two simple methods of usage are provided below as examples of how the hair styling device can be employed to achieve top-knot, low bun, updo, ponytail or other type hair styles.
Uncoiled the hair styling device as it is in the first state of the base member where the hair styling device stays straight. Put a bundle of hair through the closed loop of the hair styling device where the base member is on the bottom facing wearer's nape. Spread the hair out evenly across the concave surface. Slide the hair device toward to the tip of the hair. Further, roll away from the neck from the bottom of the device and fold the hair styling device with restraining hair by flipping them along the hair upward to the root of the hair until desired length of the hair with the concave surface of the base member facing upward. Applying force to at least one point of the base member to bend the ends of the convex side of the base member downward to snap and capture the bundle of hair into the second state of the base member. The hair device will form a circle or two small circles. The wearer can adjust the hair to cover the exposing portion of the hair styling device to make perfect style.
A second styling method begins by positioning the device identically to above. In this example, the bottom of the device is rolled towards the neck (opposite direction of rolling in the first example). Hair is rolled and folded by the rolling of the hair styling device which restrains hair as the device is rolled toward the root of the hair until the desired length of the hair is achieved with the concave surface of the base member facing downward, rather than upward as in the first example. Applying force to at least one point of the base member to bend the ends of the convex side of the base member upward to snap and capture the bundle of hair into the second state of the base member. The hair styling device will form a circle or two small circles. The wearer can adjust the hair to cover the exposed portion of the hair styling device to make a perfect style.
Furthermore, the hair styling device according to the invention, if made of a proper material with a proper size, can be used as a hair roller.
It is to be noted that the above embodiments and examples are only given for better understanding the invention, but should not be used for confining the implementations of the invention. Various modifications and similar arrangements are covered and included within the spirit and scope of the claims which are to be accorded with the broadest interpretation so as to encompass all such modifications and similar structures.
