DETAILED DESCRIPTION

[0040] Reference will now be made in detail to various embodiments of the present technology, which relate to a reversible hairclip. Although certain specific embodiments of the present technology are described, the present technology is not limited to these embodiments. On the contrary, these described embodiments are merely illustrative of the present technology, and the present technology is intended to also cover alternatives, modifications, and equivalents. Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present technology. However, it will be recognized by one of ordinary skill in the art that embodiments can be practiced without these specific details. In some instances, well known methods, procedures, compounds, compositions and mechanisms have not been described in detail as not to unnecessarily obscure aspects of embodiments of the present technology.

[0041] FIGS. 1A-4 illustrate an embodiment of a reversible hairclip 100. As shown in FIGS. 1A-1B, the reversible hairclip 100 may be worn by a user to pull their hair back into a ponytail or other hairstyle. The reversible hairclip 100, as shown in FIGS. 2A-2B, can include a band 110 and a curved pin 120. The band 110 may comprise a generally FIG. 8 shape, though other shapes, such as an oval, a triangle, square, rectangle, or any other shape, design, or pattern can be used as well (e.g., see FIGS. 9A-9C for examples of designs that can be used). Although the band 110 is depicted as substantially straight and the curved pin 120 is depicted as curved, in some embodiments, the band 110 can be curved and the pin 120 can be straight. Moreover, both the band 110 and the pin 120 could be substantially straight or curved.

[0042] In some aspects, the band 110 can comprise flexible, inelastic material. For example, the band 110 can comprise an interior spring 130 (shown in FIG. 3) coated with an exterior material. The interior spring 130 may comprise a metal or an annealed metal (e.g., zinc, steel) with spring-like properties. For example, the spring 130 may comprise a 0.3 mm cold-rolled spring steel with a hardness rated between about 42-46 Rockwell C. Although specific dimensions and hardnesses are described, other dimensions and hardnesses are contemplated and are within the scope of the present invention. The interior spring 130 is configured to bend, as shown in FIG. 3, such that the reversible hairclip 100 can secure different hair thicknesses and different hairstyles.

[0043] The exterior material coating the interior spring 130 may comprise a plastic material, such as polypropylene, thermoplastic elastomer, or the like. The exterior material may comprise a combination of two or more materials. For example, the interior spring 130 can have an injection overmold of polypropylene to provide stabilization in the secondary injection process to prevent the interior spring 130 from moving during the second overmold. Further, the interior spring 130 can have a second injection overmold of thermoplastic elastomer. The shore hardness of the exterior material is configured to sufficiently grip the user's hair in use. In some aspects, the exterior material comprises a shore hardness of about Shore 30A. In some aspects, the exterior material comprises a shore hardness of about Shore 30D to about Shore 10A. Although specific shore hardnesses are described, other shore hardnesses are contemplated and are within the scope of the present invention. A material with the described shore hardness can provide strength that prevents band 110 from indentation or deformation while still allowing the necessary flexibility to conform to the hair and desired curvature. The exterior material can also be resistant enough to bend without cracking or breaking ensuring enclosure and protection of the interior material throughout use and repeated bending of the band 110. In some aspects, the exterior material is waterproof, which prevents the interior spring 130 from contacting a fluid. The combination of the interior spring 130 overmolded with, for example, polypropylene Shore 30A, allows the band 110 to comfortably curve and grip onto objects, which gives the band 110 a flexible grip and soft-touch application. In some variants, the band 110 can comprise a single material.

[0044] In some embodiments, the band 110 comprises a first loop 116, a second loop 118, and middle section 114 between the first and second loops 116, 118. The middle section 114 may comprise a circular structure that can be configured to display a label or a logo (e.g., the circular structure 114, 214 shown in FIGS. 2A and 5A). The first and second loops 116, 118 may comprise a first end 115 and a second end 111, respectively. In some aspects, the first end 115 may comprise a first indented portion 113 and the second end 111 may comprise a second indented portion 112. The first and second indented portions 113, 112 can comprise outer diameters that are smaller than the outer diameter of the remainder of the band 110.

[0045] In some aspects, the band 110 may comprise a length of between approximately 40 millimeters to approximately 120 millimeters, approximately 50 millimeters to approximately 110 millimeters, approximately 60 millimeters to approximately 110 millimeters, approximately 70 millimeters to approximately 100 millimeters, or approximately 80 millimeters to approximately 90 millimeters. In some aspects, the band 110 may comprise a width of between approximately 10 millimeters to 50 millimeters, approximately 15 millimeters to approximately 45 millimeters, approximately 20 millimeters to approximately 40 millimeters, or approximately 25 millimeters to approximately 35 millimeters. Although specific lengths are described, other lengths of the band 110 are contemplated and are within the scope of the present invention.

[0046] As described above, the reversible hair clip 100 can include a curved pin 120. The curved pin 120 may comprise any suitable material, such as a metal (e.g., zinc, steel) or a plastic (e.g., polycarbonate, glass-reinforced polycarbonate). In some aspects, the curved pin 120 may comprise a radius of curvature of approximately 160 millimeters. In some aspects, the curved pin 120 may comprise a radius of curvature of between approximately 120 millimeters to approximately 180 millimeters, approximately 130 millimeters to approximately 170 millimeters, or approximately 140 millimeters to approximately 150 millimeters. In some aspects, the curved pin 120 may comprise a length of between approximately 50 millimeters to approximately 150 millimeters, approximately 60 millimeters to approximately 140 millimeters, approximately 70 millimeters to approximately 130 millimeters, approximately 80 millimeters to approximately 120 millimeters, or approximately 90 millimeters to approximately 110 millimeters. Although specific lengths are described, other lengths of the curved pin 120 are contemplated and are within the scope of the present invention.

[0047] In some embodiments, the curved pin 120 may comprise a knob 122, a slot 126, and a tip end 124. As shown in FIG. 4, the knob 122 of the curved pin 120, according to some embodiments, can comprise a first portion 122a and a second portion 122b. During manufacturing, the first indented portion 113 of the band 110 can be inserted between the first and second portions 122a, 122b of the knob 122 and into the slot 126. After the band 110 is inserted into the slot 126, the first and second portions 122a, 122b of the knob 122 can be sonically welded together, adhered together, welded together, or otherwise attached. The knob 122 can comprise a generally circular shape as well as other shapes, such as a generally cylindrical shape (e.g., the knob 222 shown in FIGS. 5A-5B). In some embodiments, the knob 122 is configured to pass through the first loop 116 of the band 110 such that the curved pin 120 may rotate about the band 110, as further described below with reference to FIG. 2B.

[0048] In some aspects, the slot 126 of the curved pin 120 may comprise a length of between approximately 10 millimeters to approximately 80 millimeters, approximately 20 millimeters to approximately 70 millimeters, approximately 30 millimeters to approximately 60 millimeters, or approximately 40 millimeters to approximately 50 millimeters. Although specific lengths are described, other lengths of the slot 126 are contemplated and are within the scope of the present invention.

[0049] As described above, the curved pin 120 can comprise a rigid material, such as plastic, that maintains the curvature of the curved pin 120. Referring to FIG. 2B, in some embodiments, the curved pin 120 may comprise a plurality of notches 128a on a second longitudinal side 132b (e.g., a concave side) of the curved pin 120 adjacent the tip end 124 and a plurality of notches 128b on a first longitudinal side 132a (e.g., a convex side) of the curved pin 120 adjacent the tip end 124. The plurality of notches 128a, 128b can include any number of notches (e.g., two notches, three notches, four notches, five notches, or more than five notches). In some configurations, the curved pin 120 may comprise a single notch 128a, 128b on the first longitudinal side 132a and/or the second longitudinal side 132b. The number of notches 128a on the second longitudinal side 132b can be the same or different than the number of notches 128b on the first longitudinal side 132a. For example, the first longitudinal side 132a may have no notches and the second longitudinal side 132b may have two notches 128a. Alternatively, the first longitudinal side 132a may have two notches 128b and the second longitudinal side 132b may have four notches 128a. In some aspects, the plurality of notches 128a, 128b may be configured to engage with the second indented portion 112 to secure the user's hair in use. In some aspects, the plurality of notches 128a, 128b can be configured to retain the tip end 124 of the pin within the second loop 118 of the band 110.

[0050] In some aspects, the slot 126 of the curved pin 120 may be configured to receive the first indented portion 113 of band 110. The first indented portion 113 of the band 110 can be configured to move along the length of the slot 126. The curved pin 120 may be configured to rotate about an axis of the band 110 that runs through the length of the first indented portion 113 such that the knob 122 of the pin 120 can pass through the first loop 116. The curved pin's 120 ability to rotate about the first indented portion 113 of the band 110 allows the plurality of notches 128a, 128b on the concave and convex sides 132b, 132a of the pin 120 to be able to engage with the second indented portion 112 of the band 110. This rotation, the plurality of notches 128a, 128b on both sides of the pin 120, and the concave and convex sides 132b, 132a of the pin 120 allow the hairclip 100 to be reversible and to accommodate different hair thicknesses and different hairstyles. For example, a user with thick hair may use a notch of the plurality of notches 128a, 128b closest to the tip end 124 to secure their hair with the pin 120. Or the user may wear the hairclip 100 such that the hair of the user is secured between the band 110 and the concave side 132b of the curved pin 120. Alternatively, a user with thinner hair may use a notch of the plurality of notches 128a, 128b furthest from the tip end 124. Or the user may wear the hairclip 100 such that the hair of the user is secured between the band 110 and the convex side 132a of the curved pin 120. Moreover, a user may use the hairclip 100 with one hairstyle and rotate the curved pin 120 about the band 110 to wear the hairclip 100 with a different hair style.

[0051] Other embodiments of the reversible hairclip, the curved pin and the band are illustrated in FIGS. 5A-11. FIGS. 5A-12 show embodiments of the hairclip, the curved pin, and the band that are similar to the hairclip 100, the curved pin 120, and the band 110 described with reference to FIGS. 2A and 2B and can have similar features. Reference numerals of the same or substantially the same features may share the same last two digits. The hairclip 200 shown in FIG. 5A has a curved pin 220 (FIG. 5B) with a cylindrically shaped knob 222. The curved pin 220 can include a slot 226 between first and second portions 222a, 222b of the curved pin 220. The knob 222 can comprise a unitary structure that can secure the first portion 222a of the curved pin 220 and the second portion 222b of the curved pin 220. For example, the first and second portions 222a, 222b of the curved pin 220 can each include a coupling end (not shown) at an end opposite the tip end 224 of the curved pin 220. The coupling ends of the first and second portions 222a, 222b can be received by the knob 222. The first and second portions 222a, 222b of the curved pin 220 can have a wider cross section along the curved pin 220 relative to the tip end 224 and/or the coupling ends. In some configurations, the slot 226 can be located within the wider cross section of the curved pin 220. This embodiment may also include a band 210 with a middle section 214 that comprises a circular structure 214. The circular structure 214 can be configured to display a label or a logo. The band 210 can include a first indented portion 213 and a second indented portion 212. The first indented portion 213 can be inserted into the slot 226 between the first and second portions 222a, 222b of the curved pin 220. The knob 222 can secure the band 210 within the slot 226 by securing the first and second portions 222a, 222b.

[0052] The hairclip 300 shown in FIGS. 6A-6B is similar to the embodiment of the hairclip 200 shown in FIGS. 5A-5B. The knob 322 of the curved pin 320 comprises a circular shape and the band 310 does not include a circular structure in the middle portion 314.

[0053] In the embodiment of the hairclip 400 shown in FIG. 7, the curved pin 420 does not include a knob or a plurality of notches. FIG. 8A illustrates a top view of the hairclip 500, FIG. 8B illustrates a side view of the hairclip 500, and FIG. 8C illustrates a bottom view of the hairclip 500. The knob 522 of the hairclip 500 can comprise a unitary structure configured to secure first and second portions 522a, 522b of the curved pin 520.

[0054] FIGS. 9A-9C show different embodiments of the band 810, 910, 1010 that comprise different shapes. In some embodiments, as shown in FIG. 10, the curved pin 120 comprises a knob 122 comprising a barb tip 602 and a bead 604. The bead 604 can comprise a hole 604a that extends through the bead 604. The barb tip 602 can have a first portion comprising a barbed section 601a and a neck section 603a and a second portion comprising a barbed section 601b and a neck section 603b.

[0056] Embodiments of a reversible hairclip that incorporate a decorative element are illustrated in FIGS. 12A-15E. As shown in FIG. 13, the reversible hairclip 700 can comprise a curved pin 720 and a band 710. The band 710 may comprise a generally FIG. 8 shape, though other shapes, such as an oval, a triangle, square, rectangle, or any other shape, design, or pattern can be used as well (e.g., see FIGS. 9A-9C for examples of designs that can be used). In some aspects, the band 710 can comprise an interior portion and an exterior portion. The interior portion may comprise a metal wire (e.g., zinc). The interior portion can be configured to bend such that the reversible hairclip 700 can secure different hair thicknesses and accommodate different hair styles. In some aspects, the exterior portion may comprise decoration, such as beads 719 (see FIGS. 12A-13).

[0057] In some embodiments, the band 710 comprises a first loop 716, a second loop 718, and clamp 714 between the first and second loops 116, 118. The first and second loops 716, 718 may comprise a first end 715 and a second end 711, respectively. The first end 715 may be configured to be moveably received in the slot 726 of the curved pin 720, described further below. The second end 711 may be configured to engage with the plurality of notches 728a, 728b of the curved pin 720 such that the user's hair is secured between the band 710 and the pin 720 in use.

[0058] FIGS. 14A-14D illustrate different views of the clamp 714. The clamp 714 can have a generally FIG. 8 shape with a first loop 740 and a second loop 742. The first and second loops 740, 742 of the clamp 714 may be configured to receive portions of the band 710 (shown in FIG. 13). The clamp 714 may comprise a metal material (e.g., zinc or steel) but other materials, such as a plastic material (e.g., polycarbonate), may also be used. In some aspects, the clamp 714 may comprise dimensions sufficient to provide a platform for a user's hair to push against to create more tension in the band 710 in use. In some aspects, the clamp 714 may also comprise an opening 744. During manufacturing, the portions of the band 710 may be inserted into the first or second loop 740, 742 via the opening 744. After the two portions of the band 710 are inserted into the first and second loops 740, 742, the two sides of the clamp 714 may be pushed together such that the band 710 is secured.

[0059] As shown in FIG. 13, the reversible hairclip 700 may comprise a curved pin 720. The curved pin 720 may be cast molded and comprise any suitable material, such as a metal (e.g., zinc, steel) or a plastic (e.g., polycarbonate, glass-reinforced polycarbonate). In some aspects, the curved pin 720 may comprise a radius of curvature of approximately 160 millimeters. In some aspects, the curved pin 720 may comprise a radius of curvature of between approximately 120 millimeters to approximately 180 millimeters, approximately 130 millimeters to approximately 170 millimeters, or approximately 140 millimeters to approximately 150 millimeters. In some aspects, the curved pin 720 may comprise a length of between approximately 50 millimeters to approximately 150 millimeters, approximately 60 millimeters to approximately 140 millimeters, approximately 70 millimeters to approximately 130 millimeters, approximately 80 millimeters to approximately 120 millimeters, or approximately 90 millimeters to approximately 110 millimeters. Although specific dimensions are described, other radii of curvature and lengths of the curved pin 720 are contemplated and are within the scope of the present invention.

[0060] In some embodiments, the curved pin 720 may comprise a knob 722, a slot 726, and a tip end 724. The tip end 724 may include a plurality of notches 728a, 728b adjacent both sides of the tip end 724. The plurality of notches 728a, 728b may be configured to engage with the second end 711 of the band 710. The number of notches along the tip end 724 may vary (e.g., see FIGS. 15A-15E). The slot 726 of the curved pin 720 may be configured to receive the first end 715 of the band 710. The first end 715 of the band 710 may move along the length of the slot 726. Additionally, the curved pin 720 may rotate about an axis of the band 710 that runs through the length of the first end 715. The curved pin's 720 ability to rotate about the band 710 allows the plurality of notches 728a, 728b on both sides of the pin 720 to be able to engage with the second end 711 of the band 710. In some embodiments, the hairclip 700 has two configurations. In a first configuration, the hair of the user can be secured between the concave side of the pin 720 and the band 710. In a second configuration, the hair of the user can be secured between the convex side of the pin 720 and the band 710. Thus, the user may use the hairclip 700 in the first configuration for a first hairstyle then change to the second configuration for a second hairstyle by rotating the curved pin 720 with respect to the band 710. In some variants, the two opposite sides of the band 710 may be ornamented differently (e.g., different colors, different patterns). This allows the user to wear the reversible hairclip 700 in a first configuration to match with a first outfit and in a second configuration to match with a second outfit.

[0065] FIGS. 16A-16L illustrate different views and components of a curved pin 2120. The curved pin 2120 can have similar features as the curved pins 120, 220, 320, 420, 520, 720, 1120, 1620, 1720, 1820, 1920, 2020 described herein. Reference numerals of the same or substantially the same features may share the same last two digits. For example, the curved pin 2120 can be made of any of the materials or combination of materials as described herein. Additionally, the curved pin 2120 can come in different sizes (e.g., small, medium, and large) as described above in relation to FIGS. 15A-15E.

[0066] As shown in FIGS. 16A-16D, the curved pin 2120 can include a knob 2122 configured to receive two prongs 2122a, 2122b of the curved pin 2120. For example, as shown in FIGS. 16G-16I, the knob 2122 can include a first through-hole 2136 and a second through-hole 2138. In some configurations, the first through-hole 2136 can extend approximately perpendicularly to the second through-hole 2138. The first through-hole 2136 can be configured to receive the two prongs 2122a, 2122b. As shown in FIG. 16E, the knob 2122 can be secured to the two prongs 2122a, 2122b via a securement mechanism 2134. For example, the securement mechanism 2134 can be a screw 2134 or a rod. In some configurations, the curved pin 2120 can include an opening 2122c formed between the two prongs 2122a, 2122b. The opening 2122c can be configured to align with the second through-hole 2138 when the knob 2122 is secured onto the two prongs 2122a, 2122b. In some configurations, the securement mechanism 2134 can extend through the second through-hole 2138 and the opening 2122c to secure the knob 2122 to the two prongs 2122a, 2122b.

[0067] The curved pin 2120 can be configured to be secured to any of the bands 110, 210, 310, 410, 510, 710, 810, 910, 1010 described herein. For example, the securement mechanism 2134 can be removed from the knob 2122 such that the knob 2122 can be removed from the two prongs 2122a, 2122b. A first band 110, 210, 310, 410, 510, 710, 810, 910, 1010 can be inserted into the slot 2126 and the knob 2122 can be secured onto the two prongs 2122a, 2122b to secure the first band 110, 210, 310, 410, 510, 710, 810, 910, 1010 within the slot 2126. If the user wants to wear a different style or a different sized band 110, 210, 310, 410, 510, 710, 810, 910, 1010, the user can remove the knob 2122 and the first band 110, 210, 310, 410, 510, 710, 810, 910, 1010 from the curved pin 2120. The user can then insert the second band 110, 210, 310, 410, 510, 710, 810, 910, 1010 into the slot 2126 and secure it with the knob 2122. Additionally, if the user wants to use the same band 110, 210, 310, 410, 510, 710, 810, 910, 1010 and a different style or a different sized curved pin 2120, the user can exchange the pin 2120 in this same or similar manner.

[0068] In some configurations, the curved pin 2120 may rotate about an axis of the band 110, 210, 310, 410, 510, 710, 810, 910, 1010 that runs through the length of the first end of the band 110, 210, 310, 410, 510, 710, 810, 910, 1010. In some configurations, the user can remove the band 110, 210, 310, 410, 510, 710, 810, 910, 1010 from the curved pin 2120, rotate the curved pin 2120, and reinsert the band 110, 210, 310, 410, 510, 710, 810, 910, 1010 into the curved pin 2120. The curved pin's 2120 ability to rotate about the band 110, 210, 310, 410, 510, 710, 810, 910, 1010 and the user's ability to rotate the curved pin 2120 allows the plurality of notches 2128a, 2128b on both sides of the pin 2120 to be able to engage with the second end of the band 110, 210, 310, 410, 510, 710, 810, 910, 1010. This allows the curved pin 2120 to be able to accommodate different hair thicknesses. For example, when the first longitudinal side 2132a is facing toward the band 110, 210, 310, 410, 510, 710, 810, 910, 1010, the hairclip can accommodate thinner hair or less hair. The first longitudinal side 2132a can be convex such that there is a smaller opening between the pin 2120 and the band 110, 210, 310, 410, 510, 710, 810, 910, 1010 compared to when the second longitudinal side 2132b faces the band 110, 210, 310, 410, 510, 710, 810, 910, 1010 to accommodate thinner hair or less hair. When the second longitudinal side 2132b is facing toward the band 110, 210, 310, 410, 510, 710, 810, 910, 1010, the hairclip can accommodate thicker hair or more hair. The second longitudinal side 2132b can be concave such that there is a larger opening between the pin 2120 and the band 110, 210, 310, 410, 510, 710, 810, 910, 1010 compared to when the first longitudinal side 2132a faces the band 110, 210, 310, 410, 510, 710, 810, 910, 1010 to accommodate thicker hair or more hair

[0069] As shown in FIG. 16E, the second through-hole 2138 can include a length L.sub.1 and a width W.sub.1. In some configurations, the length L.sub.1 can be between about 5 mm and about 20 mm, about 10 mm and about 15 mm, or about 8 mm. In some configurations, the width W.sub.1 can be between about 1 mm and about 10 mm, about 4 mm and about 8 mm, or about 2 mm. In some configurations, the second through-hole 2138 can include different lengths L.sub.1 and/or widths W.sub.1 for the different sizes of the curved pin 2120.

[0070] FIGS. 16J-16L illustrates an example securement mechanism 2134. The illustrated configuration of the securement mechanism 2134 is a screw 2134. The screw 2134 can have a head end comprising a first or head end 2134a, and a threaded portion 2134b comprising a second end 2134b.

[0071] As shown in FIGS. 16K-16L, the screw 2134 can include a length L.sub.2, a maximum width W.sub.2, and a minimum width W.sub.4. In some configurations, the length L.sub.2 can be between about 1 mm and about 20 mm, about 5 mm and about 15 mm, or about 5 mm. In some configurations, the maximum width W.sub.2 can be between about 1 mm and about 10 mm, about 4 mm and about 8 mm, or about 4 mm. In some configurations, the minimum width W.sub.4 can be between about 1 mm and about 10 mm, about 4 mm and about 8 mm, or about 2 mm. In some configurations, the screw 2134 can have different sizes to accommodate the different sizes of the curved pin 2120.

[0072] The head end 2134a can include an aperture sized and configured to removably receive a tool for securing the screw 2134 to the knob 2122. For example, the tool can be a wrench (e.g., a hex key or hexagon wrench) or a screwdriver. The aperture can include a width W.sub.3. In some configurations, the width W.sub.3 can be between about 1 mm and about 5 mm, or about 1.3 mm. The head end 2134a can include the maximum width W.sub.2 of the screw 2134. The head can include sidewalls that taper from the maximum width W.sub.2 of the head end 2134a to the minimum width W.sub.4 of the threaded portion 2134c at an angle Θ between the side walls. The angle Θ can be between about 60 degrees and about 120 degrees, or about 90 degrees. The head of the screw 2134 can include a length L.sub.3. In some configurations, the length L.sub.3 can be between about 0.5 mm and about 5 mm, about 2 mm and about 4 mm, or about 1.2 mm.
