- FIGS. 7A and 7B are schematic diagrams illustrating two different states of a hair clip according to still another embodiment of the present invention.
- FIGS. 8A and 8B are schematic diagrams illustrating examples of the lower clip piece according to the present invention.
- a hair clip according to an embodiment of the present invention includes an upper clip piece 21 and a lower clip piece 22 , which are operated to open a mouth 20 ( FIG. 2B ) for receiving a hair portion and close the mouth 20 ( FIG. 2A ) for retaining the hair portion.
- the upper clip piece 21 is further defined with a lip portion 211 , an arched body portion 212 , a pivotal portion 213 , and a handle portion 214 .
- the lower clip piece 22 has a tip portion 221 sustaining against the lip portion 211 of the upper clip piece 21 when the mouth 20 of the hair clip is closed, a base portion 222 for supporting the hair portion, a pivotal portion 223 for pivotally coupling to the pivotal portion 213 of the upper clip piece 21 , and a handle portion 224 to be operated cooperatively with the handle portion 214 of the upper clip piece 21 for opening or closing the mouth 20 of the hair clip.
- the base portion 222 of the lower clip piece 22 is a slightly curved and elongated piece having a curvature smaller than the arched body portion 212 , and preferably, but not necessarily, conforming to a common head's curvature.
- the arched body portion 212 of the upper clip piece 21 has a greater curvature than the base portion 222 of the lower clip piece 22 , a space created with the base portion and the arched body portion when the hair clip is in a rest state without hair inside is large enough to serve as a hair-accommodating space 200 when the hair clip is in a working state with hair inside.
- An effective room of the hair-accommodating space 200 can be defined with the coupling point of the lip portion 211 and the tip portion 221 , the arched body portion 212 , the base portion 222 , and the coupling point of the pivotal portions 213 and 223 .
- the hair-accommodating space 200 is enlarged compared to the prior art so as to be suitable for thick hair. Varying with the amount of the hair portion received and retained in the hair-accommodating space 200 , the tip portion 221 would sustain against a variable position of the lip portion 211 . Therefore, it is preferable, but not necessarily, that the lip portion 211 extends a little more advanced than the tip portion 221 to assure of the closure of the mouth 20 .
- the body portion 212 of the upper clip piece 21 includes at least two rows of teeth 2021 protruding downwards from a hair-pressing plate 2020 of the body portion 212 .
- the two rows of teeth 2021 are disposed at opposite sides of the hair-pressing plate 2020 , and if necessary in practice, additional row or rows of teeth (not shown) may be arranged between the two rows of teeth 2021 .
- the teeth 2021 are preferably, but not necessarily, extend down to a level of the base portion 222 or lower in order to further assure of the closure of the hair-accommodating space 200 .
- the teeth 2021 penetrate through the hair portion deeply, the frictional force between each tooth 2021 and hair prevents the hair clip from slipping away from hair so as to be suitable for less thick hair.
- the length, allocation and density of the teeth 2021 may vary with dimensions of other parts of the hair clip and depend on practical applications. Examples of the configurations of the teeth 2021 will be described later.
- the arched body portion in the above embodiment is shaped as a smooth curve.
- the arched body portion may be formed with one or more knuckle angles K evenly or unevenly distributed along the body portion, while the combined shape approximates an arch.
- FIGS. 3A-3C schematically illustrate some examples of hair clips with knuckle angles according to the present invention. In these figures, other elements such as teeth, if any, are omitted and not shown in order not to obstruct the view of the angles.
- the upper hair clip 311 as shown in FIG. 3A includes one knuckle angle K defined with linear and/or curved edges; the upper hair clip 312 as shown in FIG.
- a deformation member 40 may be optionally installed and can be stably installed in a hair-accommodating space 400 for depressing and further securing the hair portion inside with the knuckle configuration serving as a stopper.
- the deformation member 40 includes a first securing end 401 and a second securing end 402 to be coupled to the upper clip piece 41 and the lower clip piece 42 in any suitable detachable or non-detachable manner, e.g. adhesion, welding, hook, fasten, clamp, mount, etc. It is to be noted that the deformation member 40 may have a variety of configurations and allocations, depending on designing demands.
- FIGS. 5A-5D schematically illustrate allocation examples of a deformation member. It is to be noted that in spite the deformation member 40 is used in the examples illustrated in FIGS. 5A-5D , any other suitable deformation member, which may be similar to or different from the configuration, e.g. number, shape and/or material, of the deformation member 40 can also be used. In these figures, other elements such as teeth, if any, are omitted and not shown in order not to obstruct the view of the parts.
- the first securing end 401 is coupled to the upper clip piece 41
- the second securing end 402 is coupled to the lower clip piece 42 . Therefore, an effective room of the hair-accommodating space 400 is defined with the coupling point of the lip portion 411 of the upper clip piece 41 and the tip portion 421 of the lower clip piece 42 , the deformation member 40 , the base portion 422 of the lower clip piece 42 , and the coupling point of the pivotal portions 413 and 423 .
- the effective room of the hair-accommodating space 400 in this embodiment is smaller than that of the hair-accommodating space 200 in the embodiment illustrated in FIG. 2 , so it is suitable for relatively thin hair. Nevertheless, due to the elastically deformable feature of the deformation member 40 , the hair clip is also suitable for thick hair since the hair-accommodating space 400 is adaptively changeable with the deformation of the deformation member 40 pressed by hair.
- an effective room of the hair-accommodating space 400 is defined with the coupling point of the lip portion 411 of the upper clip piece 41 and the tip portion 421 of the lower clip piece 42 , the arched body portion 412 , the deformation member 40 , the coupling point of the pivotal portions 413 and 423 , and optionally the base portion 422 if the second securing end 402 is disposed a little more ahead of the pivot portion 423 .
- the effective room of the hair-accommodating space 400 in this embodiment is smaller than that of the hair-accommodating space 200 in the embodiment illustrated in FIG.
- the hair clip is also suitable for thick hair since the hair-accommodating space 400 is adaptively changeable with the deformation of the deformation member 40 pressed by hair.
- FIG. 5C is similar to that illustrated in FIG. 5B except that the second securing end 402 is coupled to the pivot portion 423 of the lower clip piece 42 .
- the first securing end 401 may be coupled to the lip portion 411 of the upper clip piece 41 and/or the second securing end 402 may be coupled to the pivot portion 413 of the upper clip piece 41 .
- the first securing end 401 is coupled to the lower clip piece 42
- the second securing end 402 is coupled to the upper clip piece 41 .
- FIG. 5E and FIG. 5F schematically illustrates other examples of deformation member 50 .
- the deformation member 50 is made of an elastic ring such as a rubber band.
- the upper clip piece 41 has an indentation or notch 511 in a lip portion 411 of the upper clip piece 41 , and the pivot portion 413 has also an indentation or notch 512 .
- the rubber band 50 is looped around the indentations or notches 511 and 512 .
- the upper clip piece 41 has a first securing mechanism 513 , e.g.
- An end of the rubber band 50 is secured at the first securing mechanism 513 , and the other end penetrates through the pivot portions 413 and 423 to be secured at the second securing mechanism 521 , thereby providing the desired elastically deforming feature.
- the second securing mechanism 521 may also be disposed at any suitable position on the base portion 422 of the lower clip piece 42 .
- the deformation member 50 may be provided instead of the deformation member 40 at similar positions to those exemplified in FIGS. 5A and 5D . It is to be noted that the deformation members exemplified in FIGS. 5A-5F may also be properly combined depending on practical requirements. Furthermore, it is to be noted that in spite the arched body portion 412 with a knuckle angle is used in the examples illustrated in FIGS. 5A-5F , an arched body portion with more knuckle angles or a smoothly arched body portion without a knuckle angle may also be used.
- each of the teeth 6021 may have a tapered structure. That is, it is wider near the arched body portion 612 of the upper clip piece 61 while narrower near the base portion 622 of the lower clip piece 62 .
- the arched body portion 612 of the upper clip piece 61 may be made larger than the arched body portion 212 of the upper clip piece 21 .
- the hair clip in this embodiment is advantageous in adaptivity for both thick and thin hair since the relative large arched body portion and the relative wide tooth base result in a better stopping effect for thin hair.
- hair clip when the hair clip is applied to thick hair, hair would push the upper clip piece 61 and lower clip piece 62 to move away from each other so as to create a larger space 600 .
- the reduced width of the teeth 6021 means more space reserved for hair.
- FIG. 7A and FIG. 7B schematically illustrate an open configuration and a closed configuration of a hair clip according to a further embodiment of the present invention, respectively, wherein a further example of teeth is shown.
- the teeth 7021 are configured as elongated and pointed rings.
- the pointed feature facilitates insertion of the teeth 7021 into hair.
- the rings are elastically deformable. The rings entering the hair are pressed by hair at the narrowed sides of the elongated rings, as indicated by arrows. Meanwhile, restoration of the elongated ring pressed by hair pushes hair to be securely retained in between the rings.
- the hair clip illustrated in FIG. 7A and 7B further includes a deformation member 70 .
- the deformation member 70 may be implemented with any of the above-described examples of deformation members.
- the lip portion of the upper clip piece may be made to extend forward and downward from the arched body portion, and has a down-curved free end.
- the down curving of the free end further facilitates enclosure of hair inside the hair-accommodating space.
- the base portion 222 of the lower clip piece 22 may be made of a single strip 2220 .
- the single strip may optionally have an elongated gap or a recess in the middle.
- the base portion 222 of the lower clip piece 22 may be made of a plurality of separate strips arranged in parallel, as shown in FIG. 8A , or in waves, as shown in FIG. 8B .

Abstract
Description
- The present application is a nonprovisional application claiming benefit from a prior-filed provisional application bearing a Ser. No. 62/664,252 and filed Apr. 29, 2018, and another prior-filed provisional application bearing a Ser. No. 62/745,582 and filed Oct. 15, 2018, the entities of which are incorporated herein for reference.

- A conventional hair clip consists of an upper piece and a lower piece, which are assembled with a pin and a coil spring for lever movement or an equivalent. By pressing back ends of the upper and lower pieces toward each other, the hair clip opens for accommodating hair, and a bundle of hair can be clamped by the upper and lower pieces and retained in a hair holding space defined by the upper and lower pieces when the pressing force is released. Such a hair clip, however, provides only a clamping force between the upper and lower pieces for retaining hair. Hair is likely to escape from the opening between the free ends of the upper and lower pieces, or the hair clip is likely to slide along hair flow and falls.
- Another conventional hair clip as shown in
FIG. 1 is so-called as a gator hair clip, which includes anupper piece 11 and alower piece 12, functioning for providing a clamping force as described above, and in addition, afinger piece 13 for further securing the hair clip from falling off the head. The upper andlower pieces lower pieces portions 101, and the corresponding portions of the upper andlower pieces portions 102 to be operated for pivotally opening and closing the hair-clippingportions 101. Since the hair clip is formed by adding thefinger piece 13 onto the conventional upper andlower pieces lower pieces - Therefore, there is a need to design a hair clip, which has an improved hair-retaining capability for either thin or thick hair.
- In an aspect of the present invention, a hair clip comprises an upper clip piece being a single piece defined with a lip portion, an arched body portion, an upper pivot portion and an upper handle portion; a lower clip piece defined with a tip portion, a base portion, a lower pivot portion coupled to the upper pivot portion, and a lower handle portion in cooperation with the upper handle portion, wherein a space created with the base portion and the arched body portion when the hair clip is in a rest state without hair inside is large enough to serve as a hair-accommodating space when the hair clip is in a working state with hair inside; and a plurality of teeth extending from the arched body portion of the upper clip piece toward the base portion of the lower clip piece, and being long enough to bridge the hair-accommodating space between the arched body portion and the base portion. The hair clip in the working state is switchable between an open configuration and a closed configuration by operating the upper handle portion and the lower handle portion to have the upper clip piece and the lower clip piece pivot on the upper pivot portion and the lower pivot portion. When the hair clip is in the open configuration, the lip portion of the upper clip piece is apart from the tip portion of the lower clip piece to open a mouth for receiving hair therefrom. When the hair clip is in the closed configuration, the lip portion of the upper clip piece overbites the tip portion of the lower clip piece so that the hair in the hair-accommodating space is sharply separated from adjacent hair which is excluded from the hair clip.
- In another aspect of the present invention, a hair clip comprises an upper clip piece being a single piece defined with a lip portion, an arched body portion, an upper pivot portion and an upper handle portion; a lower clip piece defined with a tip portion, a base portion, a lower pivot portion coupled to the upper pivot portion, and a lower handle portion in cooperation with the upper handle portion, wherein a space created with the base portion and the arched body portion when the hair clip is in a rest state without hair inside is large enough to serve as a hair-accommodating space when the hair clip is in a working state with hair inside; a plurality of teeth extending from the arched body portion of the upper clip piece toward the base portion of the lower clip piece; and a deformation member disposed between the upper clip piece and the lower clip piece for adaptively changing an effective room of the hair-accommodating space. The hair clip in the working state is switchable between an open configuration and a closed configuration by operating the upper handle portion and the lower handle portion to have the upper clip piece and the lower clip piece pivot on the upper pivot portion and the lower pivot portion. When the hair clip is in the open configuration, the lip portion of the upper clip piece is apart from the tip portion of the lower clip piece to open a mouth for receiving hair therefrom. When the hair clip is in the closed configuration, the lip portion of the upper clip piece overbites the tip portion of the lower clip piece to close mouth so that the hair in the hair-accommodating space is sharply separated from adjacent hair which is excluded from the hair clip.

It is to be noted that the following descriptions of preferred embodiments of this invention are presented herein for purpose of illustration and description only; it is not intended to be exhaustive or to be limited to the precise form disclosed.
- As illustrated in
FIG. 2A andFIG. 2B , a hair clip according to an embodiment of the present invention includes anupper clip piece 21 and alower clip piece 22, which are operated to open a mouth 20 (FIG. 2B ) for receiving a hair portion and close the mouth 20 (FIG. 2A ) for retaining the hair portion. Theupper clip piece 21 is further defined with alip portion 211, anarched body portion 212, apivotal portion 213, and ahandle portion 214. Thelower clip piece 22 has atip portion 221 sustaining against thelip portion 211 of theupper clip piece 21 when themouth 20 of the hair clip is closed, abase portion 222 for supporting the hair portion, apivotal portion 223 for pivotally coupling to thepivotal portion 213 of theupper clip piece 21, and ahandle portion 224 to be operated cooperatively with thehandle portion 214 of theupper clip piece 21 for opening or closing themouth 20 of the hair clip. Thebase portion 222 of thelower clip piece 22 is a slightly curved and elongated piece having a curvature smaller than thearched body portion 212, and preferably, but not necessarily, conforming to a common head's curvature. Since thearched body portion 212 of theupper clip piece 21 has a greater curvature than thebase portion 222 of thelower clip piece 22, a space created with the base portion and the arched body portion when the hair clip is in a rest state without hair inside is large enough to serve as a hair-accommodatingspace 200 when the hair clip is in a working state with hair inside. An effective room of the hair-accommodatingspace 200 can be defined with the coupling point of thelip portion 211 and thetip portion 221, thearched body portion 212, thebase portion 222, and the coupling point of thepivotal portions arched body portion 212, the hair-accommodatingspace 200 is enlarged compared to the prior art so as to be suitable for thick hair. Varying with the amount of the hair portion received and retained in the hair-accommodatingspace 200, thetip portion 221 would sustain against a variable position of thelip portion 211. Therefore, it is preferable, but not necessarily, that thelip portion 211 extends a little more advanced than thetip portion 221 to assure of the closure of themouth 20. - In this embodiment, the
body portion 212 of theupper clip piece 21 includes at least two rows ofteeth 2021 protruding downwards from a hair-pressingplate 2020 of thebody portion 212. The two rows ofteeth 2021 are disposed at opposite sides of the hair-pressingplate 2020, and if necessary in practice, additional row or rows of teeth (not shown) may be arranged between the two rows ofteeth 2021. Theteeth 2021 are preferably, but not necessarily, extend down to a level of thebase portion 222 or lower in order to further assure of the closure of the hair-accommodatingspace 200. Furthermore, since theteeth 2021 penetrate through the hair portion deeply, the frictional force between eachtooth 2021 and hair prevents the hair clip from slipping away from hair so as to be suitable for less thick hair. The length, allocation and density of theteeth 2021 may vary with dimensions of other parts of the hair clip and depend on practical applications. Examples of the configurations of theteeth 2021 will be described later. - The arched body portion in the above embodiment is shaped as a smooth curve. Alternatively, the arched body portion may be formed with one or more knuckle angles K evenly or unevenly distributed along the body portion, while the combined shape approximates an arch.
FIGS. 3A-3C schematically illustrate some examples of hair clips with knuckle angles according to the present invention. In these figures, other elements such as teeth, if any, are omitted and not shown in order not to obstruct the view of the angles. Theupper hair clip 311 as shown inFIG. 3A includes one knuckle angle K defined with linear and/or curved edges; theupper hair clip 312 as shown inFIG. 3B includes two knuckle angles K defined with linear and/or curved edges; and theupper hair clip 313 as shown inFIG. 3C includes more knuckle angles K defined with linear and/or curved edges. With the knuckle angle or angles K, specific functional effects can be provided for further improving hair-retaining capability and/or specific visual effects can be made for decorative purposes. For example, as shown inFIG. 4 , adeformation member 40 may be optionally installed and can be stably installed in a hair-accommodatingspace 400 for depressing and further securing the hair portion inside with the knuckle configuration serving as a stopper. A space created with the base portion and the arched body portion when the hair clip is in a rest state without hair inside is large enough to serve as the hair-accommodatingspace 400 when the hair clip is in a working state with hair inside. Thedeformation member 40 includes a first securingend 401 and asecond securing end 402 to be coupled to theupper clip piece 41 and thelower clip piece 42 in any suitable detachable or non-detachable manner, e.g. adhesion, welding, hook, fasten, clamp, mount, etc. It is to be noted that thedeformation member 40 may have a variety of configurations and allocations, depending on designing demands. -
FIGS. 5A-5D schematically illustrate allocation examples of a deformation member. It is to be noted that in spite thedeformation member 40 is used in the examples illustrated inFIGS. 5A-5D , any other suitable deformation member, which may be similar to or different from the configuration, e.g. number, shape and/or material, of thedeformation member 40 can also be used. In these figures, other elements such as teeth, if any, are omitted and not shown in order not to obstruct the view of the parts. - In the example illustrated in
FIG. 5A , the first securingend 401 is coupled to theupper clip piece 41, and the second securingend 402 is coupled to thelower clip piece 42. Therefore, an effective room of the hair-accommodatingspace 400 is defined with the coupling point of thelip portion 411 of theupper clip piece 41 and thetip portion 421 of thelower clip piece 42, thedeformation member 40, thebase portion 422 of thelower clip piece 42, and the coupling point of thepivotal portions space 400 in this embodiment is smaller than that of the hair-accommodatingspace 200 in the embodiment illustrated inFIG. 2 , so it is suitable for relatively thin hair. Nevertheless, due to the elastically deformable feature of thedeformation member 40, the hair clip is also suitable for thick hair since the hair-accommodatingspace 400 is adaptively changeable with the deformation of thedeformation member 40 pressed by hair. - In the example illustrated in
FIG. 5B , both the first securingend 401 and the second securingend 402 are coupled to thelower clip piece 42. Therefore, an effective room of the hair-accommodatingspace 400 is defined with the coupling point of thelip portion 411 of theupper clip piece 41 and thetip portion 421 of thelower clip piece 42, thearched body portion 412, thedeformation member 40, the coupling point of thepivotal portions base portion 422 if the second securingend 402 is disposed a little more ahead of thepivot portion 423. The effective room of the hair-accommodatingspace 400 in this embodiment is smaller than that of the hair-accommodatingspace 200 in the embodiment illustrated inFIG. 2 , so it is suitable for relatively thin hair. Nevertheless, due to the elastically deformable feature of thedeformation member 40, the hair clip is also suitable for thick hair since the hair-accommodatingspace 400 is adaptively changeable with the deformation of thedeformation member 40 pressed by hair. - The example illustrated in
FIG. 5C is similar to that illustrated inFIG. 5B except that the second securingend 402 is coupled to thepivot portion 423 of thelower clip piece 42. Alternatively, the first securingend 401 may be coupled to thelip portion 411 of theupper clip piece 41 and/or the second securingend 402 may be coupled to thepivot portion 413 of theupper clip piece 41. In the example illustrated inFIG. 5D , the first securingend 401 is coupled to thelower clip piece 42, and the second securingend 402 is coupled to theupper clip piece 41. -
FIG. 5E andFIG. 5F schematically illustrates other examples ofdeformation member 50. Thedeformation member 50 is made of an elastic ring such as a rubber band. In the example shown inFIG. 5E , theupper clip piece 41 has an indentation or notch 511 in alip portion 411 of theupper clip piece 41, and thepivot portion 413 has also an indentation or notch 512. Therubber band 50 is looped around the indentations ornotches FIG. 5F , theupper clip piece 41 has afirst securing mechanism 513, e.g. ahook 5131 in aslot 5132 as shown in the enlarged view, in thelip portion 411, and asecond securing mechanism 521, e.g ahook 5211 on apost 5212 as shown in the enlarged view, is disposed on thehandle portion 424 of thelower clip piece 42. An end of therubber band 50 is secured at thefirst securing mechanism 513, and the other end penetrates through thepivot portions second securing mechanism 521, thereby providing the desired elastically deforming feature. Alternatively, thesecond securing mechanism 521 may also be disposed at any suitable position on thebase portion 422 of thelower clip piece 42. In other examples, thedeformation member 50 may be provided instead of thedeformation member 40 at similar positions to those exemplified inFIGS. 5A and 5D . It is to be noted that the deformation members exemplified inFIGS. 5A-5F may also be properly combined depending on practical requirements. Furthermore, it is to be noted that in spite thearched body portion 412 with a knuckle angle is used in the examples illustrated inFIGS. 5A-5F , an arched body portion with more knuckle angles or a smoothly arched body portion without a knuckle angle may also be used. - Hereinafter, examples of teeth will be described. In the examples shown in
FIG. 2 , theteeth 2021 are of a linear structure substantially extending downwards in parallel, and each of theteeth 2021 is substantially of the same or slightly reduced width from top to bottom. Alternatively, referring toFIG. 6 , each of theteeth 6021 may have a tapered structure. That is, it is wider near thearched body portion 612 of theupper clip piece 61 while narrower near thebase portion 622 of thelower clip piece 62. In addition, thearched body portion 612 of theupper clip piece 61 may be made larger than thearched body portion 212 of theupper clip piece 21. The hair clip in this embodiment is advantageous in adaptivity for both thick and thin hair since the relative large arched body portion and the relative wide tooth base result in a better stopping effect for thin hair. On the other hand, when the hair clip is applied to thick hair, hair would push theupper clip piece 61 andlower clip piece 62 to move away from each other so as to create alarger space 600. Meanwhile, the reduced width of theteeth 6021 means more space reserved for hair. -
FIG. 7A andFIG. 7B schematically illustrate an open configuration and a closed configuration of a hair clip according to a further embodiment of the present invention, respectively, wherein a further example of teeth is shown. In this example, theteeth 7021 are configured as elongated and pointed rings. The pointed feature facilitates insertion of theteeth 7021 into hair. It is preferred that the rings are elastically deformable. The rings entering the hair are pressed by hair at the narrowed sides of the elongated rings, as indicated by arrows. Meanwhile, restoration of the elongated ring pressed by hair pushes hair to be securely retained in between the rings. which means theteeth 7021 are deformable to retain a resilient force when pressed by hair entering the hair-accommodatingspace 700, and theteeth 7021 can restore to the original configuration after hair is released from the hair clip. For example, the elastic deformability can be caused by using an elastically deformable material to form theteeth 7021. In another case that theteeth 7021 is integrally formed with the relatively rigidupper clip piece 71, the elastic deformable feature can be achieved by using a thin enough ring. The hair clip illustrated inFIG. 7A and 7B further includes adeformation member 70. Thedeformation member 70 may be implemented with any of the above-described examples of deformation members. - As shown in the embodiments described above, the lip portion of the upper clip piece may be made to extend forward and downward from the arched body portion, and has a down-curved free end. The down curving of the free end further facilitates enclosure of hair inside the hair-accommodating space.
- Referring back to
FIG. 2B , thebase portion 222 of thelower clip piece 22 may be made of asingle strip 2220. The single strip may optionally have an elongated gap or a recess in the middle. Alternatively, thebase portion 222 of thelower clip piece 22 may be made of a plurality of separate strips arranged in parallel, as shown inFIG. 8A , or in waves, as shown inFIG. 8B . In these embodiments, there may be small bumps or mini-posts 2221 provided in the middle of thestrip 2220 or in the middle recess of thestrip 2220. Alternatively, the small bumps or mini-posts 2221 may be distributed randomly over thestrip 2220 for increasing frictional forces. Furthermore, theteeth 2021 may extend down to at least agap 2023 between two of theseparate strips 2220, or lower. - All the designs as embodied above intend to make a well enclosed and adaptively adjusted accommodation space for hair. With the above-described designs, hair can be securely retained in the hair clip.
- While the invention has been described in terms of what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention needs not be limited to the disclosed embodiments. On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims which are to be accorded with the broadest interpretation so as to encompass all such modifications and similar structures.
