Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates generally to hair extension
and adornment, and more particularly to a method and apparatus for
fastening bundles of hair using a hair clip, wherein a bundle of
supplemental hair may be fastened to a bundle of human hair to
produce longer hair length, greater hair volume, or a new hair
style.
[0003] 2. Description of the Prior Art
[0004] A person may wish to supplement their own natural hair with
supplemental hair in order to lengthen or increase the volume of
hair to change their appearance or to try a new fashionable hair
style. Thus, a person with short hair, or a person with sparse
hair, may have a hair style that requires longer hair, or greater
hair volume. The supplemental hair may be made of natural human
hair or synthetic fibers made to look like natural human hair.
[0005] In the prior art, supplemental hair strands may be attached
or bonded to natural hair by several methods, such as tying,
weaving, or gluing the supplemental hair to the person's natural
hair.
[0006] An example of attaching supplemental hair by weaving or
braiding is disclosed in U.S. Pat. No. 4,982,748 issued to
Trimarchi. U.S. Pat. No. 4,934,387 issued to Megna discloses a
method of attaching supplemental hair to human hair using
adhesives.
[0007] Some disadvantages of attaching supplemental hair with
adhesives include the need to apply heat to a person's hair and the
use of a hot iron near a person's scalp. Given a choice, clients
receiving supplemental hair would prefer a method that does not use
heat on their hair or near their scalp.
[0008] Another disadvantage is the loosening of the adhesive over
time and when exposed to water, shampoo, conditioner, and other
hair care and styling products.
[0009] Therefore, there is a need for an improved method and system
for applying supplemental hair to natural human hair that provides
a secure, easy-to-make fastening between supplemental hair and
natural hair that does not use heat and that does not loosen over
time with changes in moisture and exposure to chemicals or
cleaners.
SUMMARY OF THE INVENTION
[0010] The invention is directed to a clip and a method and
apparatus for using the clip to attach supplemental hair to natural
human hair. After a bundle of growing human hair is selected, a
bundle of supplemental hair is located together with the selected
bundle of growing human hair to form a joint at an attachment site.
The joint is inserted into an opening between legs of a U-shaped
hair clip, and legs of the hair clip are bent around the joint and
crimped. Strands in the bundle of supplemental hair may be
pre-glued to one another.
[0011] An apparatus for fastening a bundle of supplemental hair to
a bundle of growing human hair includes a base having an anvil.
Anvil surfaces guide and orient the clip so that the clip legs
enter bend-guiding troughs. An arm assembly is movably connected to
the base, and may be used to store and dispense clips. A driver is
coupled to the arm assembly for pressing an open hair clip into the
anvil to close and crimp the clip.
[0012] A clip for fastening hair bundles has a crown and coupled to
either side of the crown. The clip may have a length greater than
the width spaced apart legs. The clip legs are made of a malleable
material.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0042] With reference now to the drawings, and in particular with
reference to FIG. 1, there is depicted an apparatus for fastening a
clip to bundles of hair in accordance with the method and apparatus
of the present invention. Although apparatus 20 resembles a
conventional stapler, and to some degree operates like one, there
are important differences because the clip is unique and
non-conventional. The fastening of the clip is preferably used to
attach, bind, fasten, or join a bundle of supplemental hair, which
may be synthetic hair or human hair, to a bundle of human hair
growing from a person's scalp for the purpose of creating the
appearance of longer or fuller hair, or for creating a new hair
style. Alternatively, a clip of the present invention may be used
to bundle or fasten strands of hair, synthetic or natural, to
create hair pieces, or portions thereof, that may later be attached
and worn on a person's head as a part of a new hair style. A clip
of the present invention may be used to bind together strands,
cords, lanyards, or other objects that fit together within an open
clip.
[0043] FIG. 28 shows how clip fastening apparatus 20 may be used to
fasten supplemental hair bundle 39 to human hair strands 38 growing
from a person's scalp. As shown in FIGS. 1, 2, 3, 28, and 30, clip
fastening apparatus 20 includes base 22, which is coupled to arm
assembly 24 by hinge 26. Arm assembly 24 pivots about hinge 26 to
move arm assembly 24 toward base 22 in a manner similar to a common
stapler.
[0044] In a preferred embodiment, clip fastening apparatus 20
stores, dispenses and closes clip 30 to fasten bundles of hair.
Clip 30 is shown in FIGS. 4-6, which depicts U-shaped clip 30
having two opposing legs 32 connected by a rounded or arched crown
34. Legs 32 define opening 78, which may receive strands or bundles
of hair for fastening. Although not required, leg ends 36 are
preferably serrated in order to more effectively engage or grip
stands of hair in the bundles of hair that are fastened to one
another. Clip 30 has a length 118 measured along the ridge of crown
34, and a width 116 measured between points where legs 32 join
crown 34. (See FIGS. 5 and 6) In a preferred embodiment, length 118
is greater than width 116.
[0045] In a preferred embodiment, clip 30 is made from a malleable
material so that legs 32 may be bent and curved inward toward one
another and back toward crown 34 in order to close the clip and
clinch strands of hair in the bundles of hair that are to be
fastened to one another. FIG. 27 shows a cross-sectional end view
of a closed clip 30A that clinches hair strands 38 and a pre-glued
hair bundle 39. Note that when clip 30 or 30A is closed, legs 32
are curved toward one another, and may be curved back toward crown
34. Leg ends 36 may cross as alternating portions of the serrations
interleave. Ends 36 push into the hair bundles and grip the hair to
prevent longitudinal movement of the hair clip along either hair
bundle.
[0046] The embodiment of clip 30A shown in FIGS. 26 and 27 includes
tooth 40 formed in the area of crown 34. Tooth 40 projects into the
area of clinched hair strands 38 in order to provide an additional
grip to prevent hair strands 38 from sliding out of the grasp of
the closed hair clip 30A. FIG. 27 also shows a cross section of
hair bundle 39 fastened to hair strands 38. Hair bundle 39 may
include strands of hair, natural or synthetic, that have been
pre-glued to one another by an adhesive so that the bundle may be
easily handled and placed near a selected bundle of growing human
hair to form a joint or attachment site, as shown in FIG. 28. For
additional detail regarding hair bundle 39 and the method of making
same, refer to U.S. patent Ser. No. ______ (U.S. Patent Application
Publication No. 20040011372), which is hereby incorporated by
reference.
[0047] As shown in FIG. 26, which is a plan view of clip 30A before
being bent into a U-shape, tooth 40 is located in the center of
clip 30A in an area that will be along the arch of crown 34. Tooth
40 may be formed during a die-stamping operation, which may be used
to cut the shape of clip 30A from a flat sheet of material, such as
brass or another malleable metal or plastic. The material of clip
30 or 30A may also be painted or coated or otherwise colored to
match hair colors so that clip 30 or 30A will not be so noticeable
in a person's hair. Alternatively, colors may be selected so that
colored clips are noticed and become part of a hair style similar
to hair styles using colored beads.
[0048] In FIGS. 2 and 3, clip fastening apparatus 20 is shown with
arm assembly 24 opened to a loading position wherein strips 58 (see
FIG. 3) of clips 30 or 30A (note that references herein to clip 30
also refer to clip 30A) may be inserted in a manner similar to the
way staples are loaded into an open channel of a typical paper
stapler. Base 22 includes anvil 28, which, as described in more
detail below, is used for temporarily positioning bundles of hair,
for assisting in separating a dispensed clip from a next clip in a
glued strip of clips, and for closing a clip around bundles of hair
to fasten the bundles of hair to one another. Arm assembly 24
includes three elements pivotally connected by hinge 26: clip
dispenser arm 42, driver arm 44, and clip retainer 46. All such arm
elements pivot with respect to base 22 about hinge 26.
[0049] When clip dispenser arm 42 is opened to the loading
position, where an angle between clip dispenser arm 42 and base 22
is large and may be obtuse, a strip of clips 58, which is made of
clips 30 glued to one another at legs 32, may be loaded into clip
channel 48 in clip dispenser arm 42. Clips 30 are stored in clip
channel 48 before they are dispensed from dispenser arm opening 50
(see FIGS. 1, 2, 3, 30, 31, and 32). As arm assembly 24 is opened
to this wide loading angle, clip feed spring retractor 56 engages
clip strip feeder 52 (see FIG. 3A), compressing feeder spring 54
and moving clip strip feeder 52 toward hinge 26. Thus, when clip
dispenser arm 42 is opened to the loading position, clip feed
spring retractor 56, which is pivotally coupled at one end to base
22, compresses feeder spring 54 with the other end by sliding clip
strip feeder 52 in clip channel 48 back toward hinge 26. With clip
strip feeder 52 retracted in this manner there is space to load a
new strip of clips 58.
[0050] The space in clip channel 48 for storing clips, such as clip
strip 58, may be referred to more generally as a clip chamber. This
is a space to hold many clips prior to being dispensed through
dispenser arm opening 50. In other embodiments, clips 30 may be
stored and dispensed in different ways. For example, some
embodiments may store clips loosely, or individually, where they
are not glued or connected to one another.
[0051] Because the strip of clips 58 may buckle and rise out of
clip channel 48 when the spring pressure behind clip strip feeder
52 is applied to the newly loaded strip, clip retainer 46 may be
pivoted, after loading the strip, into a position above clip
channel 48 where it will keep the newly loaded strip of clips 58
supported and retained in a straight line within clip channel 48.
Thus, surface 76 (See FIGS. 2, 3, and 32) of clip retainer 46 is
positioned slightly above and possibly touching crowns 34 of clips
30 after being loaded in clip channel 48.
[0052] With reference now to FIGS. 7-11, various views of anvil 28
are depicted. As illustrated therein, anvil 28 includes anvil base
94 having mounting holes 80 for receiving fasteners that fasten
anvil 28 to base 22. Appropriate fasteners that may be used include
screws, rivets, or the like. In a preferred embodiment, anvil 28
includes two guide arms 98, with one guide arm 98 including next
clip support arm 64. Guide arms 98 extend away from, and
substantially perpendicular to, anvil base 94. Next clip support
arm 64 is narrow enough and long enough to extend into dispenser
arm opening 50 in clip dispenser arm 42 when dispenser arm 42 is
closed toward base 22. Next clip support arm 64 extends away from,
and substantially perpendicular to, anvil base 94, extending
further than guide arm 98. The function and operation of next clip
support arm 64 is described more completely below.
[0053] Guide arms 98 have guide surfaces 72, which are facing each
other and positioned adjacent to two bend-guiding troughs 74
(troughs 74). Guide surfaces 72 are used to guide clip legs 32 into
troughs 74. Troughs 74 are preferably adjoining, concave curved
surfaces for guiding and bending legs 32 as clip 30 is bent closed
to clinch strands of hair 38. Troughs 74 may be described as a
surface formed by moving an arc or similar conic curve (the
generatrix) along a line (the directrix) perpendicular to the
curve. An axis of troughs 74 may be located at the center of the
arc or conic curve. An axial length of trough 74 may be the length
of the axis or directrix.
[0054] Troughs 74 are preferably open-ended because surfaces are
not needed to bend clip 30 lengthwise, along the axis of the clip,
to shorten the length of the clip. Open-ended troughs 74 allows the
placement of strands of hair close to, or in, troughs 74. Troughs
74 have outer edges 114 running parallel to the axis of trough 74
wherein the curved surface of trough 74 joins guide surface 72.
Inner edge 120 also runs parallel to the axis of trough 74 and are
preferably touching, as shown in FIG. 7.
[0055] Guide surfaces 72 are preferably nearly perpendicular to
anvil base 94, with a slight tilt or opening away from the outer
edges 114 of troughs 74. Guide surfaces 72 brace legs 32 of clip 30
so that clip 30 does not rotate around the clip axis, so that legs
32 enter troughs 74 perpendicular to anvil base 94. Guide surfaces
72 and troughs 74 form a cavity that receives the hair bundles and
that forms clip 30 around the hair bundles during the closing or
crimping process. The bottom of the cavity is contoured by troughs
74 so as to bend legs 32 of clip 30 more than 90.degree., thereby
causing legs 32 not only to enclose the hair bundles, but to
interlock.
[0056] Anvil 28 may also include openings 82 for receiving and
retaining hair strand retainer springs 84, which spring is
illustrated in FIGS. 9, 11, 16 and 17. The purposes of hair strand
retainer springs 84 is to temporarily position and hold strands or
bundles of hair together to form a joint at an attachment site
before clip 30 is pressed into anvil 28 to fasten the strands or
bundles of hair together. Hair strand retainer springs 84 are
preferably made from a resilient material, such as steel wire.
FIGS. 9 and 11 show hair strand retainer springs 84 installed in
openings 82 in anvil 28, where they can position strands of hair
between and slightly away from anvil surfaces 72 so that legs 32
can move past the strands along anvil surfaces 72. One or more
retainer springs 84 may be installed on either or both sides of
guiding arms 98 as shown in FIG. 11. One end of retainer spring 84
is fastened to anvil base 94 and may extend into recess 96, while
the non-fastened end is free to move in opening 82 when strands or
bundles of hair are inserted between hair strand retainer springs
84.
[0057] Referring now to FIGS. 12-15, various views of driver 68 are
depicted.
[0058] Driver 68 is used to press clip 30 into anvil 28. As
illustrated, driver 68 is includes shaft 86 mounted perpendicularly
to mounting base 88. Mounting base 88 includes mounting holes 90
which receive fasteners for fastening mounting base 88 to driver
arm 44 (See FIG. 3). Appropriate fasteners may include screws,
rivets, or the like. Driving surface 92 is located at the end of
shaft 86, and preferably has a concave curvature adapted to match
or conform to the curvature of crown 34 of clip 30.
[0059] With reference now to FIGS. 18-20, various views of driver
arm spring 70 are depicted. As shown, driver arm spring 70 includes
a base 100 with mounting holes 102. Driver arm spring 70 is mounted
to driver arm 44 with fasteners in mounting holes 102. Appropriate
fasteners that may be used include screws, rivets, or the like.
Spring arm 104 applies force to clip retainer 46 to retract driver
68 back into dispenser arm opening 50 after a clip 30 is closed.
Driver arm spring 70 is preferably made from a springy resilient
material, such as steel or plastic.
[0060] FIG. 21 is an illustration of arm assembly spring 66. As
shown, arm assembly spring 66 includes base 106 with one or more
mounting holes 108 for receiving fasteners to secure spring 66 to
base 22. Screws, rivets, or the like may be used as fasteners.
Spring arm 110 applies force to arm assembly 24 to keep arm
assembly 24 open or away from base 22, ready to receive hair
bundles before a fastener is attached, or retracting arm assembly
24 after a clip attachment. Arm assembly spring 66 includes slot
112 so that spring 66 will not interfere with clip feed spring
retractor 56 when clip dispenser arm 42 is opened to a loading
position as shown in FIG. 2.
[0061] With regard to the operation of clip fastening apparatus 20,
several steps in the process of dispensing and closing a clip 30
are depicted in FIGS. 22-25. To start the operation, an operator
places bundle 38 of natural hair in the anvil cavity. The operator
then places supplemental hair bundle 39 (i.e. a second hair bundle)
in the cavity (or vice versa, so that two or more bundles are in
the cavity). The operator may also place hair bundles together, and
then place both in the anvil cavity. Once the bundles are in the
cavity, the operator squeezes arm assembly 24 and base 22 to force
driver 68 toward the cavity. Hair bundles 38 and 39 are shown in
the cavity of anvil 28 in FIGS. 22-25. Hair retaining springs 84
are only shown in FIG. 22 for clarity, and in a preferred
embodiment they are also used (but not shown) in FIGS. 23-25 to
hold hair bundles 38 and 39 in place while the clip is closed and
crimped.
[0062] As shown in FIG. 22, a strip of clips 58 is in position for
dispensing clip 60, which is the first clip beneath driver 68.
Clips 30, including dispensed clip 60 and next clip 62, are glued
to one another at legs 32. Driver 68, which is carried by driver
arm 44, has been moved toward base 22 and anvil 28 so that next
clip support arm 64 on anvil 28 is positioned in opening 78 (see
FIG. 6) of next clip 62 and contacts next clip 62 on the inside of
crown 34. Next clip 62 is held in place by next clip support arm
64. When arm assembly 24 moves toward base 22 arm assembly spring
66 (See FIGS. 3, 21, 26, and 30) is compressed. When driver 68
moves toward dispensed clip 60 and out through dispenser arm
opening 50 (See FIGS. 30-32) driver arm spring 70 is
compressed.
[0063] Note that FIG. 22 depicts the position of strip of clips 58,
next clip support arm 64, and driver 68 at an instant before
dispensed clip 60 is broken apart from next clip 62 as it is driven
toward anvil 28.
[0064] FIG. 23 shows dispensed clip 60 after it is has been
separated from next clip 62 and pushed downward (with respect to
the orientation of the Figs.) by driver 68. Driver 68, which is
attached to driver arm 44, has continued to move toward base 22
thereby continuing to compress driver arm spring 70 (See also FIGS.
30-32).
[0065] At the point in the process shown in FIG. 23, legs 32 of
clip 30 are beginning to contact and slide along guide surfaces 72,
which surfaces are more clearly indicated in FIGS. 9 and 22. Guide
surfaces 72 help keep clip 30 in a vertical position as additional
force is applied to crown 34 of clip 30 in order to bend legs 32
closed.
[0066] As shown in FIG. 24, clip legs 32 have entered troughs 74
and are beginning to curve toward one another as legs 32 move along
the bend-guiding surfaces of troughs 74. In FIG. 24, driver 68
applies force to crown 34 of dispensed clip 60 as driver 68
continues to move toward base 22. Force on crown 34 and the
directing of the force by the curved surfaces of troughs 74 cause
the bending and closing of legs 32.
[0067] In FIG. 25, dispensed clip 60 has been closed after legs 32
have followed the curved surface of troughs 74. Legs 32 are
beginning to overlap to further compress any strands or bundles of
hair that may be in dispensed clip 60, as the serrated ends of leg
ends 36 interdigitate.
[0068] The manufacturing of strip of clips 58 may begin with a flat
piece of metal, similar to that shown in FIG. 26. The flat metal is
then bent to form crown 34 with legs 32 that have flat parallel
surfaces. The clips are then joined by an adhesive at the outer
flat parallel surfaces of legs 32 of adjacent clips 30. A mold or
channel may be used to hold a series of clips in a straight line,
with leg ends 36 coplanar, as the adhesive sets.
[0069] Since the clip fastening method and apparatus of the present
invention does not require a hot iron to melt adhesive, the present
invention has the advantage of securely fastening bundles or
strands or hair without using a very hot iron on a person's hair,
or near a person's scalp. In addition, the fastening may be used
without applying adhesive or other chemicals to a person's hair. In
many cases, the joint formed between hair strands using the hair
clip of the present invention will last longer, and withstand more
shampoos and other chemical treatments for hair, than hair
attachments that use adhesives. Use of the present invention is
simple and fast. Unlike a conventional stapler, which drives a
fastener through the objects being fastened, clip fastening
apparatus 20 fastens a clip around objects, which may require less
force.
[0070] The hair clips of the present invention may be removed by
opening legs 32 to loosen the grip of clip 30.
[0071] The foregoing description of a preferred embodiment of the
invention has been presented for the purpose of illustration and
description. It is not intended to be exhaustive or to limit the
invention to the precise form disclosed. Obvious modifications or
variations are possible in light of the above teachings. The
embodiment was chosen and described to provide the best
illustration of the principles of the invention and its practical
application, and to enable one of ordinary skill in the art to
utilize the invention in various embodiments and with various
modifications as are suited to the particular use contemplated. All
such modifications and variations are within the scope of the
invention as determined by the appended claims when interpreted in
accordance with the breadth to which they are fairly, legally, and
equitably entitled.
