- FIG. 4A illustrates a shape of the tube on a cross-sectional plane taken along line 4 A in FIG. 4B , in which the tube's cross-section forms a closed loop.
- the closed loop of the tube 20 is generally in an oval or elliptical shape and smoothly curved generally throughout.
- the length L 2 in the axis X is substantially larger than the length L 1 in the axis Y.
- the height of the tube 20 in axis Z is smaller than the length L 2 in the axis X, although not necessary nor limited thereto.
- FIGS. 4C-4F illustrate, not limiting, sectional shapes of tubes according to other embodiments.
- Each illustrated tube 50 , 56 , 61 and 62 is substantially longer in the X axis than in the Y axis like the tube 20 of FIG. 4A .
- the tube 50 of FIG. 4C has a generally track shape, in which two linear portions 54 are combined with two half circled end portions 52 .
- the tube 56 of FIG. 4D is generally oval or elliptical like the tube 20 of FIG. 4A except that the two ends 58 in the X axis are pointed.
- the tube 61 of FIG. 4E has a pear or egg shaped section.
- the tube 62 of FIG. 4F has a diamond or rhombus shape that is composed of four substantially straight sections connected to form a closed loop.
- the configurations of the illustrated tubes 20 , 50 , 56 , 61 and 62 provide anisotropic deformability. Specifically, the tubes are deformable more easily when a crimping force is applied in one direction than when the same crimping force is applied in another direction on a sectional plane as shown in FIGS. 4A , 4 C- 4 F. More specifically, the tubes are deformable more easily when a crimping force is applied in a first direction than when the same crimping force is applied in another direction perpendicular to the first direction on a sectional plane as shown in FIGS. 4A , 4 C- 4 F.
- the tube 20 is shaped or configured to deform more easily when a crimping force is applied between two diagonally opposing points 25 along the Y axis than when the same amount of crimping force is applied between two diagonally opposing points 27 along the X axis. In other words, it would take a smaller amount of crimping force to deform the tube 20 in the Y axis than to deform the tube 20 in the X axis. In the configuration of the oval tube 20 , it appears that deforming the tube 20 by applying crimping force between the two points 25 would be substantially easier than by applying crimping force between any two diagonally opposing points of the tube 20 on the illustrated sectional plane, i.e., the plane of the drawing sheet.
- the tubes 50 , 56 , 61 and 62 are shaped or configured to deform more easily when a crimping force is applied to the tubes along the Y axis than when the same amount of crimping force is applied along the X axis.
- deforming the tubes by applying crimping force between the two nearest diagonally opposing points would be easier than by applying crimping force between any other two diagonally opposing points on the tube 20 .
- sectional shapes providing similar anisotropic deformability to substitute the tubes 20 , 50 , 56 , 61 and 62 .
- the sectional shape of the tubes is configured such that the length in one direction (in the X axis) is substantially greater than the length in another direction perpendicular to the one direction (in the Y axis).
- the length in the X axis is greater than the length in the Y axis by more than about 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, 110%, 120%, 130%, 140%, 150%, 160%, 170%, 180%, 190%, 200%, 210%, 220%, 230%, 240%, 250%, 260%, 270%, 280%, 290%, 300%, 310%, 320%, 330%, 340%, 350%, 360%, 370%, 380%, 390% or 400% of the length of the tube in the Y axis.
- these sectional shapes are smoothly contoured or curved throughout.
- the sectional shapes may include at least one pointed portion.
- the sectional shapes may include at least one straight portion.

- FIG. 5B the blades of the crimping tool 65 contact the tube 20 about the two diagonally opposing points 27 .
- the orientation of FIG. 5B is less desirable than the orientation of FIG. 5A to hair beauticians or stylists in their hair extension service context. Typically, hair beauticians and stylists prefer speedy and easy handling of the crimping tool 65 in their hair extension process.
- this orientation of FIG. 5B requires substantially a lot more crimping force when compared to the orientation of FIG. 5A .
- this orientation of FIG. 5B requires opening of the crimping tool 65 almost to their maximum to grab the tube 20 as shown. Further, it would be more difficult to grab the tube 20 in the orientation shown in FIG. 5B than in the orientation shown in FIG. 5A as more contact can be made in the orientation of FIG. 5A than the other. At least for these reasons, hair beauticians and stylists are induced to grab the tube 20 as in the orientation of FIG. 5A or similar orientations.
- the blades of the crimping tool 65 contact the tube 20 about two points 298 that are located between the point 25 and the point 27 .
- the orientation of FIG. 5C is less desirable than the orientation of FIG. 5A for the same reasons as discussed in connection with the orientation of FIG. 5B . Therefore, hair beauticians and stylists are induced to change the tube 20 toward the orientation of FIG. 5A if the tube 20 is first grabbed in an orientation as in FIG. 5C . Further, when grabbing the tube 20 in an orientation like FIG. 5C , the tube 20 may turn its orientation to the orientation of FIG. 5A as crimping force is applied to the tube 20 . Therefore, self-inducement of the orientation can occur in the process of crimping the tube 20 .
- inducement of crimping orientation is discussed only in terms of the tube 20 , the same can apply to the other illustrated tubes 50 , 56 , 61 and 62 .

- the length in the X axis is greater than the length in the Y axis by more than about 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, 110%, 120%, 130%, 140%, 150%, 160%, 170%, 180%, 190%, 200%, 210%, 220%, 230%, 240%, 250%, 260%, 270%, 280%, 290%, 300%, 310%, 320%, 330%, 340%, 350%, 360%, 370%, 380%, 390% or 400% of the length of the tube in the Y axis.
- surfaces of the tube 20 where a contact of the crimping tool 65 is desired or preferred are smoothly contoured or curved, or substantially flat to provide easy and stable grabbing and crimping when the crimping tool 65 contacts the surfaces.
- the portions of tubes corresponding to the area near the point 25 of the tube 20 shown in FIGS. 3 and 5A are smoothly contoured or substantially flat.
- surfaces of the tube 20 where a contact of the crimping tool 65 is not preferable or desirable may be pointed or include bumps or other structures that could hinder stable grabbing or crimping with the crimping tool 65 .
- the portions of tubes corresponding to the area near the point 27 of the tube 20 of FIGS. 3 and 5A are pointed.
- the tubes for the extension hair piece 10 are made of such materials that are sufficiently deformable when crimping with a typical hair beautician's crimping tool as well recognized by skilled artisans. Further, in embodiments, the tubes are made of such materials that can sustain the deformed configuration afterward when no similar force is applied thereto using a typical hair beautician's crimping tool.
- the tubes including those illustrated are made of a metallic material, such as steel, copper, aluminum, tin or alloys although not limited thereto.
- certain synthetic materials including plastic materials can be used in the tubes, although not all metallic and plastic materials have needed characteristics for the tubes. However, skilled artisan in the relevant technology would appreciate various characteristics of materials and would be able to choose proper materials.
- the tubes are manufactured in such thicknesses that their shape can be deformed when a crimping force is applied using the crimping tool 65 typically used by hair beauticians and stylists. Also, the tubes are manufactured in such thicknesses that, once deformed, their deformed configurations can be sustained.
- the thickness of the tubes may vary depending upon choice of the materials again to provide proper level of deformability and structural sustainability. In some embodiments, tubes have a substantially uniform thickness throughout although not limited thereto. In other embodiments, a single tube has substantially different thicknesses at its different locations thereof. Skilled artisan in the relevant technology would be able to choose proper thicknesses in view of the choice of materials.

- 1. Field
- The present disclosure relates to hair extension, and more particularly, to an extension hair piece including a tube and a hair bundle connected to the tube.
- 2. Discussion of Related Technology
- Generally, the hair extension technology connects one or more extension hair pieces to hair of a person or an animal. The extension hair pieces are to make the person/animal's hair look longer or thicker and/or add color accents to the person/animal's hair. The extension hair pieces for hair extension are in various forms and shapes, and include hair weaves, widgets, etc. In this field, typically beauticians or hair stylists provide services of connecting extension hair pieces to hair of their customers. The foregoing discussion in this section is to provide general background information, and does not constitute an admission of prior art.
- One aspect of the invention provides a hair extension device, which comprises: a tube configured to deform more easily in a first direction than in a second direction when the same amount of crimping force is applied to the tube, wherein the first and second directions are on a cross-sectional plane, in which the tube's cross-section forms a closed loop; a hair bundle comprising a plurality of extension hair strands bound together; and a link linking the hair bundle to the tube.

FIG. 1 depicts hair extension using anextension hair piece 10 according to one embodiment. Hair extension with theextension hair piece 10 makeshair 12 of theperson 14 look longer and/or thicker. In the illustrated embodiment, theextension hair piece 10 is connected tohair 12 of aperson 14. Although this disclosure is made only in the context of extending hair of a human, the same can be applied to animals. Referring toFIG. 2 , theextension hair piece 10 includes ahair bundle 22 and atube 20. In the illustrated embodiment, thehair bundle 22 includes a plurality ofextension hair strands 32 bound together at atip portion 34. In the illustrated embodiment, thetube 20 is connected to thehair bundle 22 via alink 24. In the illustrated embodiment, thelink 24 includes two flexible cords or strings, which are tied with thetube 20. Tying of the cords with thetube 20 and thereby forming thelink 24 will be discussed in more detail later. -
FIGS. 3A-3D illustrate a hair extension process using thehair extension piece 10 in accordance with one embodiment. First, as inFIG. 3A , a hair beautician stylist selects from a person's hair 12 a plurality ofhair strands 16 that are to be used in connecting thehair extension piece 10. Then thehair strands 16 are inserted into thetube 20 of thehair extension piece 10 so that thehair strands 16 pass through thetube 20 as illustrated inFIG. 3B . Optionally, the hair beautician may use a device 154 that makes the insertion easy, which is well known in the hair extension industry and practice. Subsequently, the location of thetube 20 is adjusted relative to the scalp of theperson 14. Afterward, the hair beautician crimps and flattens thetube 20 using a crimpingtool 165, which is well known in the hair extension industry and practice.FIG. 3C illustrates a cross-sectional view of thetube 20,hair strands 16 and cords that provide thelink 24, along with the crimpingtool 165.FIG. 3D illustrates completed hair extension using the foregoing technique andhair extension piece 10 in accordance with an embodiment. - Referring back to
FIG. 2 , theextension hair strands 32 are bound together at thetip portion 34 using a glue or adhesive such as a polyurethane resin. In other embodiments, theextension hair strands 32 are clipped together at thetip 34, using a clipping device (not shown), which skilled artisan would well appreciate. In the illustrated embodiment, thetip portion 34 where theextension hair strands 32 are bound together is wrapped with a wrapping material such as a paper or plastic tape andindividual strands 32 are not shown in thetip portion 34, although not limited thereto. - In embodiments, the
extension hair strands 32 are natural human hair or animal hair. Typically, natural human hair or animal hair are processed/or dyed to be bound to produce thehair bundle 22. In other embodiments, theextension hair strands 32 are synthetic artificial ones. Theextension hair strands 32 are dyed or colored to create colors of natural human hair or color accents. In embodiments, the length and thickness of the extension hair strands may vary. - As noted above, the
tube 20 connects between the person'shair 12 and thehair bundle 32. Referring toFIGS. 2 , 4A and 4B, thetube 20 defines ahollow space 26.FIG. 4A illustrates a shape of the tube on a cross-sectional plane taken alongline 4A inFIG. 4B , in which the tube's cross-section forms a closed loop. In the illustrated embodiment, the closed loop of thetube 20 is generally in an oval or elliptical shape and smoothly curved generally throughout. Further, the length L2 in the axis X is substantially larger than the length L1 in the axis Y. InFIG. 4B , the height of thetube 20 in axis Z is smaller than the length L2 in the axis X, although not necessary nor limited thereto. -
FIGS. 4C-4F illustrate, not limiting, sectional shapes of tubes according to other embodiments. Each illustratedtube tube 20 ofFIG. 4A . Thetube 50 ofFIG. 4C has a generally track shape, in which twolinear portions 54 are combined with two half circledend portions 52. Thetube 56 ofFIG. 4D is generally oval or elliptical like thetube 20 ofFIG. 4A except that the two ends 58 in the X axis are pointed. Thetube 61 ofFIG. 4E has a pear or egg shaped section. Thetube 62 ofFIG. 4F has a diamond or rhombus shape that is composed of four substantially straight sections connected to form a closed loop. - The configurations of the illustrated
tubes FIGS. 4A , 4C-4F. More specifically, the tubes are deformable more easily when a crimping force is applied in a first direction than when the same crimping force is applied in another direction perpendicular to the first direction on a sectional plane as shown inFIGS. 4A , 4C-4F. - For example, the
tube 20 is shaped or configured to deform more easily when a crimping force is applied between two diagonally opposingpoints 25 along the Y axis than when the same amount of crimping force is applied between two diagonally opposingpoints 27 along the X axis. In other words, it would take a smaller amount of crimping force to deform thetube 20 in the Y axis than to deform thetube 20 in the X axis. In the configuration of theoval tube 20, it appears that deforming thetube 20 by applying crimping force between the twopoints 25 would be substantially easier than by applying crimping force between any two diagonally opposing points of thetube 20 on the illustrated sectional plane, i.e., the plane of the drawing sheet. - Likewise, the
tubes tube tube 20. - Although not illustrated, there are numerous other sectional shapes providing similar anisotropic deformability to substitute the
tubes - The tubes according to embodiments are shaped or configured to induce application of crimping force to one or more particular orientations when attempting to crimp the tubes with a crimping tool.
FIGS. 5A-5C illustrate various orientations of thetube 20 relative to a crimping tool 65, and hence various orientations of crimping force application. The orientation ofFIG. 5A is preferred or desirable, in which the blades of the crimping tool 65 contact about the two diagonally opposingpoints 25 on the wall of thetube 20. - Referring to
FIG. 5B , the blades of the crimping tool 65 contact thetube 20 about the two diagonally opposing points 27. The orientation ofFIG. 5B is less desirable than the orientation ofFIG. 5A to hair beauticians or stylists in their hair extension service context. Typically, hair beauticians and stylists prefer speedy and easy handling of the crimping tool 65 in their hair extension process. However, this orientation ofFIG. 5B requires substantially a lot more crimping force when compared to the orientation ofFIG. 5A . Also, this orientation ofFIG. 5B requires opening of the crimping tool 65 almost to their maximum to grab thetube 20 as shown. Further, it would be more difficult to grab thetube 20 in the orientation shown inFIG. 5B than in the orientation shown inFIG. 5A as more contact can be made in the orientation ofFIG. 5A than the other. At least for these reasons, hair beauticians and stylists are induced to grab thetube 20 as in the orientation ofFIG. 5A or similar orientations. - Referring to
FIG. 5C , the blades of the crimping tool 65 contact thetube 20 about twopoints 298 that are located between thepoint 25 and thepoint 27. The orientation ofFIG. 5C is less desirable than the orientation ofFIG. 5A for the same reasons as discussed in connection with the orientation ofFIG. 5B . Therefore, hair beauticians and stylists are induced to change thetube 20 toward the orientation ofFIG. 5A if thetube 20 is first grabbed in an orientation as inFIG. 5C . Further, when grabbing thetube 20 in an orientation likeFIG. 5C , thetube 20 may turn its orientation to the orientation ofFIG. 5A as crimping force is applied to thetube 20. Therefore, self-inducement of the orientation can occur in the process of crimping thetube 20. - Although inducement of crimping orientation is discussed only in terms of the
tube 20, the same can apply to the other illustratedtubes FIGS. 4A , 4C-4F. For example, the length in the X axis is greater than the length in the Y axis by more than about 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, 110%, 120%, 130%, 140%, 150%, 160%, 170%, 180%, 190%, 200%, 210%, 220%, 230%, 240%, 250%, 260%, 270%, 280%, 290%, 300%, 310%, 320%, 330%, 340%, 350%, 360%, 370%, 380%, 390% or 400% of the length of the tube in the Y axis. - In some embodiments, surfaces of the
tube 20 where a contact of the crimping tool 65 is desired or preferred are smoothly contoured or curved, or substantially flat to provide easy and stable grabbing and crimping when the crimping tool 65 contacts the surfaces. For example, the portions of tubes corresponding to the area near thepoint 25 of thetube 20 shown inFIGS. 3 and 5A are smoothly contoured or substantially flat. In some embodiments, surfaces of thetube 20 where a contact of the crimping tool 65 is not preferable or desirable may be pointed or include bumps or other structures that could hinder stable grabbing or crimping with the crimping tool 65. For example, the portions of tubes corresponding to the area near thepoint 27 of thetube 20 ofFIGS. 3 and 5A are pointed. - In embodiments, the tubes for the
extension hair piece 10 are made of such materials that are sufficiently deformable when crimping with a typical hair beautician's crimping tool as well recognized by skilled artisans. Further, in embodiments, the tubes are made of such materials that can sustain the deformed configuration afterward when no similar force is applied thereto using a typical hair beautician's crimping tool. In embodiments, the tubes including those illustrated are made of a metallic material, such as steel, copper, aluminum, tin or alloys although not limited thereto. In other embodiments, certain synthetic materials including plastic materials can be used in the tubes, although not all metallic and plastic materials have needed characteristics for the tubes. However, skilled artisan in the relevant technology would appreciate various characteristics of materials and would be able to choose proper materials. - The tubes are manufactured in such thicknesses that their shape can be deformed when a crimping force is applied using the crimping tool 65 typically used by hair beauticians and stylists. Also, the tubes are manufactured in such thicknesses that, once deformed, their deformed configurations can be sustained. The thickness of the tubes may vary depending upon choice of the materials again to provide proper level of deformability and structural sustainability. In some embodiments, tubes have a substantially uniform thickness throughout although not limited thereto. In other embodiments, a single tube has substantially different thicknesses at its different locations thereof. Skilled artisan in the relevant technology would be able to choose proper thicknesses in view of the choice of materials.
- Typically, the tubes are produced using metal or plastic extrusion technology although not limited thereto. Although the production method and technology are not discussed in detail, skilled artisans in the relevant art would appreciate technology and adopt proper technology as advancements arrive given parameters of the tubes.
- Referring back to
FIG. 2 , thelink 24 flexibly links between thetube 20 and thehair bundle 22 to provide theextension hair piece 10. In the illustrated embodiment, more specifically, thelink 24 is tied with thetube 20 and fixed to thetip portion 34 of thehair bundle 22. Now, one embodiment of making theextension hair piece 10 is discussed with reference toFIGS. 6A-6C . - In
step 51, aflexible string 76 is folded in half. Instep 53, two ends 72 or the folded middle 74 of thestring 76 is inserted through thetube 20 as shown inFIG. 6A . Subsequently instep 55, the two ends 72 of thestring 76 are inserted through a space 82 defined by the folded middle portion and thetube 20. Then instep 57, thefree end 72 is pulled away, and thestring 76 becomes tied with thetube 20. Afterward instep 59, the ends 72 of thestring 76 are integrated with thetip portion 34 of thehair bundle 22 using an appropriate method. In one embodiment, the two ends 72 are bonded to the tip portion using an appropriate adhesive or glue. Then a portion of thestring 76 interposed between thetube 20 and thetip portion 34 becomes thelink 24. - In some embodiments, when or prior to integrating the
string 76 to thetip portion 34, a portion of thestring 76 may be cut to shorten the length of thelink 24. Some small length of thelink 24 is desirable in order to allow independent and flexible movement of the bundle relative to thetube 20. On the other hand, if thelink 24 between thetube 20 and thetip portion 34 is too long, thehair bundle 22 could swing too much independent of the hair 12 (FIG. 1 ) of theperson 14, which is not desirable. - For the sake of explanation,
FIGS. 7A and 7B are two embodiments, each illustrating a cross-sectional view of thetube 20 after flattening along with thestring 76 andhair strands 16. In the embodiment ofFIG. 7A two portions of thestring 76 are generally centered within the flattenedtube 20, whereas in the embodiment ofFIG. 7A twostring portions 76 are off the center of the flattenedtube 20. As a result, the centeredstring portions 76 ofFIG. 7A contact and engage withmore hair strands 16 than the decenteredstring portions 76 ofFIG. 7B . Therefore, the centeredstring portions 76 ofFIG. 7A would have more friction withhair strands 76 and be less slippery than the decenteredstring portions 76 ofFIG. 7B when theextension hair piece 10 is pulled away. - In embodiments, the position of string or
string portions 76 is adjusted for more effective engagement of thetube 20 withhair strands 16. More specifically, the position of string orstring portions 76 is adjusted relative to thetube 20 or its configuration to maximize contacts, friction and engagement betweenhair strands 16 and surfaces of thestring 76 after thetube 20 is crimped. In one embodiment, the string orstring portions 76 are generally positioned in the center or middle along a longer axis (X axis inFIGS. 4A , 4C-4F). Referring toFIG. 7C , for example, the twostring portions 76 are tied with a generally central portion of the tube's wall in the X axis. In other configurations of the tube inFIGS. 4C-4F , the string orstring portions 76 are tied with the tube's wall in its central portion along the X axis. - In some embodiments, the string or
string portions 76 are tightly tied to the central portion of the tube's wall to prevent undesirable displacements. Further in some embodiments, the string orstring portions 76 are glued to the central portion of the tube's wall to prevent its displacement from the central portion. In one embodiment, a portion of thestring 76 positioned inside thetube 20 is glued to an interior surface of thetube 20. In another embodiment, a portion of thestring 76 positioned outside the 26 of thetube 20 is glued to an exterior surface of thetube 20. In another embodiment, thestring 76 is bonded to both the interior and exterior surfaces of thetube 20. Bonding of thestring 76 can be performed with any appropriate material and at any appropriate stage of making theextension hair piece 10 or thereafter. For example, bonding of thestring 76 is made between thesteps steps steps step 59. - In one embodiment illustrated in
FIG. 7D , thetube 20 has anotch 132 in its wall generally at the center in its X axis. Although not illustrated, the string orstring portions 76 are tied with the notched portion of thetube 20. Thenotch 132 will facilitate tying of the string orstring portions 76 at the central portion of the tube's wall and further to prevent displacement of the string orstring portions 76 from the central portion once tied properly. In embodiments, thenotch 132 can be made in various configurations and sizes. In some embodiments, the string orstring portions 76 are glued as well as tied with the notched portion of the tube's wall. - In embodiments, the
string 76 for thelink 24 can be made of a material or made in a form that can provide a surface roughness. The surface roughness is needed to provide friction with hair strands 16 (FIG. 3D ) of theperson 14 to further the non-slip engagement once thehair piece 10 has been connected to the person'shair 12. In some embodiments, thestring 76 is made of a fiber string. In other embodiments, thestring 76 is made of a non-fiber string. In some embodiments, thestring 76 is a twisted one, and in other embodiments the string is a non-twisted one. In embodiments, thestring 76 is sufficiently flexible to allow thehair bundle 22 to move relative to thetube 20 given an appropriate distance between thetube 20 and thehair bundle 22. Also, in some embodiments, thestring 76 can be elastic. - Other Connections Between Tube and Hair Bundle

FIGS. 8A-8C provide other forms of linking between thetube 20 and thehair bundle 22. InFIG. 8A , astring 102 is tied with thetube 20, in which thestring 102 is inserted through thetube 20 unfolded to turn around the wall of thetube 20 and knotted at the bottom. Then, two ends 101 of thesingle strand string 102 are put together and attached to thetip portion 34. In one embodiment, a portion of thestring 102 is bonded to thetube 20 as discussed above in connection with the embodiments ofFIGS. 6A and 6B . - In another embodiment of
FIG. 8B , a portion of astring 112 enters into thetube 20 and glued to an interior surface of thetube 20. In the illustrated embodiment, the bottom end of thestring 112 is fixed to thetip portion 34 of thehair bundle 22. In another embodiment ofFIG. 8C , astring 122 has a hook portion 124 hanging over a top edge of thetube 20. In the additional embodiments ofFIGS. 8B and 8C , thestring - In some embodiments, an extension hair piece may include two or more hair bundles. Referring to
