CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is a non-provisional application claiming benefit from a U.S. Provisional Patent Application bearing a Ser. No. 62/584,888 and filed Nov. 12, 2017, contents of which are incorporated herein for reference.

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.

 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 around longitudinal axis, such that the base member 10 has a concave surface 14, a convex surface 13 and two longitudinal ends 11 and 12. A second stable state where the base member has at least one wrap-around cylindrical structure coiled around lateral axis where the curved ridge 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.

An embodiment of the holding member 20 is pliable as shown in FIG. 3A and FIG. 3B. 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. The material of the holding member 20 is non-metallic and includes at least one selected from the group consisting of 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 two opposite parts 301 and 302, each of which connects each the end 201, 202 of the holding member 20 with recesses 3010 and 3020 at, or near, each corresponding the longitudinal end 101, 102 of the base member 10 such that the holding member 20 is opposed to the concave surface 14 of the base member 10. The essential element of the attaching member 30 is that it forms a closed loop for the base member 10 and the holding member 20, such that the base member's concave surface 14 faces the inside of the loop 97 and the entire longitudinal length of the base member 10 is available to hold hair.

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.

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.

When the base member 10 is made of materials with a potential of ‘sharp’ edges, a protective barrier may be employed to prevent potential injury to a user from such edges. This barrier may be a coating of plastic, or similar, or covering of fabric, leather or similar.

The attachment to form this closed loop can be a physical affixing with glue, rivet, bolt and nut, clamp, staple, welding, soldering, heat staking, dipping, injection molding, stamping or other similar. A hook, eye, tab, or other device on either the base member 10 or the holding member 20 in concert with each other may also form the requisite closed loop 97.

An example of the attaching member 30 is schematically illustrated in FIG. 3B, which the attaching member 30 functions for connecting each the end 201, 202 of the holding member 20 to corresponding each the longitudinal end 101, 102 of the base member 10 on the convex surface, wherein the holding member 20 wraps over the longitudinal end 101, 102 and along a longitudinal length of the concave surface 14, such that the entire longitudinal length of the base member 101 is available to hold hair, whereby the holding member forms the closed loop 97 with the base member 10 for receiving and restraining a bundle of hair.

In the embodiment illustrated in FIG. 4B and FIG. 4D, the attaching member 30 is surrounding and encasing at least the longitudinal ends 101, 102 of the base member 10, includes at least one selected from the group consisting of fabric, silicone, plastic, polyester, Synthetic Wig and rubber, such that the attaching member 30 integrates the holding member 20 to the base member 10 by including at least one of the group consisting of glue, tape, sewing or injection molding. For example, an injection molded holding member may include ‘caps’ at either end to securely slide over the ends of the base member and retaining the base and holding members in the required loop relationship (see FIG. 4C and FIG. 4D). In an alternative example, the base member 10 may be inserted into a fabric or similar, tube. The ends of the fabric tube would then be attached to each other by sewing, glue or other similar method (see FIG. 4A and FIG. 4B). The fabric tube then serves as both the holding member 20 and attaching member 30 with the base member 10 retained within it. In a further example, the base member 10 is cloth fitted into a synthetic wig or similar. The holding member 20 would then be attached to each the longitudinal end 101, 102 of encased base member 10 by sewing, glue, tape or other similar method.

In the embodiment illustrated in FIG. 5, the attaching member 30 is at least one pair of fasteners 39 and 40 such as a rivet, bolt and nut, clamp, staple, glue, welding, soldering, heat staking, dipping or a combination of any two of these for affixing the holding member to the base member. The holding member 20 is generally affixed at both the longitudinal ends 101 and 102 of the base member 10 but that can be affected in any of several ways. For example, the fasteners 39 and 40 may be attached at the longitudinal ends 101 and 102 of the base member 10 on the concave surface 14. Alternatively, the fasteners 39 and 40 may be implemented with bolts, screws or any other fixing members 301 and 302 attached at the longitudinal ends 101 and 102 of the base member 10 on the convex surface 13 as exemplified in FIG. 3B. The holding member 20 may wrap over the longitudinal ends 101 and 102 of the base member 10 from the concave side 14 and be affixed to the opposite convex side 13 so as to have the holding member 20 cover the entire length of the base member 10 and allowing the maximum volume of hair between the base and holding members 10 and 20.

The attaching member 30 can be integrated with the base member 10 as a part of the base member and/or integrated with the holding member 20 as a part of the holding member to provide an attaching effect. In the embodiment illustrated in FIG. 6A, the attaching member is a pair of hooks 31 and 32; in the embodiment illustrated in FIG. 6B, the attaching member is a pair of tabs 33 and 34; in the embodiment illustrated in FIG. 6C, the attaching member is a pair of loops 35 and 36; and in the embodiment illustrated in FIG. 6D, the attaching member is a pair of eyeholes 37 and 38. It is understood that a combination of any two of these can also be used as the attaching member. FIG. 6E schematically illustrates a hair styling device includes an attaching member as shown in FIG. 6D. For example, the implementation would be the base member 10 cut with the pair of holes 37 and 38 punched at the longitudinal ends 101 and 102 into which a string, lace or ribbon is inserted and knotted, or similarly stopped on the opposite side of the base member 10 so that the length of the holding member 10 string or lace rest on the concave surface 14 of the base member 10. The attaching member 30 can be integrated with the base member 10 as punched holes and integrated with the holding member 20 as knots to provide attaching method. In another example where the attaching member 30 integrates on both the base member 10 and the holding member 20, eyeholes or loops are used as the portion of the attaching member 30 on the base member 10, then hooks on the string, lace or ribbon holding member are hooked into the eye holes or loops to complete the attaching member.

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 exposed 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.

Compared with the '251 patent, the hair styling device according to the invention improves the usage when replacing the elastic strip with a strip made of inelastic, yet pliable, material. In addition, an inflexible attachment may be used. Optionally, when the hair styling device according to the invention comprises a single bistable strip, and a single inelastic strip disposed in an end-to-end configuration, the styling function can be accomplished better. The inelastic material provides a tighter hold of hair against the bistable strip than the elastic material. The inelastic strip may also be designed to be longer than the bistable strip to assure that the entire length of the bistable strip is available to hold hair. Varying lengths of the bistable strip, and therefore the entire device, can be used to accommodate varying volumes of hair. Further, the attachment between the bistable strip and the inelastic strip is not flexible. The bistable strip and the inelastic strip are designed to remain securely in alignment restricting movement of the base member and the holding member relative to each other. Furthermore, the benefits of using inelastic material (e.g. fabric, ribbon, vinyl, leather or similar) are aesthetic and tactile. The hair accessory can look good and have a variety of ‘feels’.

Furthermore, compared with the '176 patent, the invention creates a closed holding space. It always uses only a single bistable strip of metal, plastic, silicone or similar which has the requisite bistable states. Instead of a second bistable strip, the second strip of this design is a non-metallic pliable material fabric, ribbon, vinyl, leather or similar. The second strip is attached at both longitudinal ends with to the first bistable strip to create a closed holding space. Such that the device prevents the hair from slipping out and reduces the users' effort to manipulate two bistable strips simultaneously while styling, particularly during the transition of the bistable strips from their first to second state. When a non-metallic bistable strip is used, the invention further provides a safety improvement and additional convenience for the user to wear anywhere that security officials at airports or in similar security situations, might refuse to allow a metal strip, particularly such a strip which is already relatively sharp with the potential to be further sharpened. In addition to being easier to use and holding hair better, the instant design is simpler to produce. It requires less effort to produce and the single bistable strip on this device is less material than previous devices, which use two such strips.

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.
