Description

RELATED APPLICATION DATA

The present application is a non-provisional application based on, and claims the priority benefit of, co-pending U.S. provisional application Ser. No. 60/643,198, which was filed on Jan. 12, 2005, and is expressly incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates generally to a device for clasps and clips for retaining strands of hair and, more particularly, to clasps and clips having a friction member for improved gripping of the strands of hair.

BACKGROUND OF THE DISCLOSURE

Devices for retaining hair, such as barrettes, bobby pins, claw clips, and hair clips, are generally known in the art. These devices come in various shapes and sizes including various adornments to improve the esthetic appeal of the hair retaining device. One of the ongoing difficulties with these devices, however, is the inability to prevent these devices from sliding off of or moving relative to the strands of hair to be engaged and retained by the devices. For example, during normal movement throughout the day these devices tend to loose their grip around the strands of hair, thereby loosening the bundle of hair the devices are intended to retain.
One such device is disclosed in U.S. Pat. No. 6,257,251 to Burleson et al. which discloses a cushion coated hair clip having low friction surfaces. The hair clip includes a layer of compressible, resilient cushion material such as natural rubber or elastomer synthetic resin material, or cellular plastic foam that is bonded onto the hair engaging surfaces. A thick non-porous outer coating layer is applied to the compressible cushion layers for providing smooth, low friction, non-sticking surfacing for directly engaging the hair.
Another such device is disclosed in U.S. Pat. No. 5,996,593 to Horman which discloses a hair clip. The hair clip includes an alternating sequence of rubber teeth secured to surfaces of each of two clamping arms which are in an interlocking mating relationship, thereby providing for a greater surface area between the clamping arms of the hair clip.
Another such device is disclosed in U.S. Pat. No. 3,590,830 to Hannum which discloses a barrette. The barrette includes a pair of hingedly connected outer and inner body members. The first body member is provided with means for grippingly, non-slidably engaging the hair of the wearer. The other body member is provided with lifting means, including means for manually retracting and extending the lift means relative to the body member to permit unhindered insertion of the body member in the hair of the user.
These and similar retaining devices, however, do not provide the desired gripping ability for retaining a bundle of hair, or are too costly to manufacturer, and/or cause damage to the user's hair.

SUMMARY OF THE DISCLOSURE

In accordance with one aspect of the disclosure, a hair retaining clip having a base, a locking arm, a hinge, and a locking mechanism is disclosed. The base includes a first end, a second end and a first elongate section that is resiliently movable relative to the base. The locking arm includes a first end, a second end, and a second elongate section that operatively engages the first elongate section in a closed position. The hinge is disposed on and pivotally connects the first ends of the base and the locking arm. The locking mechanism is disposed on the second end of base for locking the clip in a closed position. At least one of the first and second elongate sections are entirely constructed from a high friction material.
In accordance to another aspect of the disclosure, a hair retaining clip having a base, a locking arm, a hinge, a locking mechanism, and an insert is disclosed. The base includes a first end, a second end and an elongate section that is resiliently movable relative to the base. The locking arm includes a first end, a second end, and an elongate web that operatively engages the elongate section in a closed position. The hinge is disposed on and pivotally connects the first ends of the base and the locking arm. The locking mechanism is disposed on the second end of the base for locking the clip in a closed position. The insert is disposed in an aperture of the web and is constructed from a high friction material.
In accordance to another aspect of the disclosure, a hair retaining clip having a base, a locking arm, a hinge, a locking mechanism, and a gripping portion is disclosed. The base includes a first end, a second end and a first elongate section that is resiliently movable relative to the base. The locking arm includes a first end, a second end, and a second elongate section that operatively engages the first elongate section in a closed position. The hinge is disposed on and pivotally connects the first ends of the base and the locking arm. The locking mechanism is disposed on the second end of the base for locking the clip in a closed position. The gripping portion is permanently attached to at least one of the first and second elongate sections.

While the method and device described herein are susceptible to various modifications and alternative constructions, certain illustrative embodiments thereof have been shown in the drawings and will be described below in detail. It should be understood, however, that there is no intention to limit the invention to the specific forms disclosed, but on the contrary, the intention is to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the disclosure and the appended claims.

DETAILED DESCRIPTION

Referring now to the drawings and with specific reference to FIGS. 1-3, a hair clip constructed according to the teachings of the disclosure is generally depicted by reference numeral 20. As shown therein, the hair clip 20 in this exemplary embodiment includes a fastener 22 fixedly attached to a shroud 24. The shroud 24 may be attached to the fastener 22 in various ways known to those skilled in the art, and in this exemplary embodiment is fastened to the fastener 22 via screws 26. The shroud 24 may be a separate piece from the fastener 22 and may, in an alternative embodiment, be constructed in one unitary or over-molded piece.
The fastener 22 includes a base 28 operatively connected to a locking arm 30. The base 28 has a generally elongate shape and is fixedly attached to the shroud 24. The base 28 also includes a spring or biasing member 31 that may be slidably and/or fixedly connected to the base 28. The spring member 31 has a generally elongate shape and, in this embodiment, is constructed from a high friction or non-slip material such as, for example, Styrene, Polypropylene, Polyethylene, Styrene, Nylon, Kostrate, Styrene Acrylonitrile (SAN), Polyvinyl Chloride (PVC), Acetate, Neoprene or a Thermoplastic Elastomer (TPE) material. The spring member 31 may also include a thinning or reduced center section, which may be adapted to engage the base 28, as seen in FIG. 3, and may possess a variety of textures and geometries that would provide an increased holding power. Furthermore, as seen in FIG. 2, the spring member 31 may include a bow or curvature, such that spring member 31 can absorb a force placed on the fastener 22 when the clip 20 is in a closed position similar to FIGS. 1 and 3. The locking arm 30 also has a generally elongate shape and may include one or more apertures 33 that may receive portions of the spring member 31.
A hinge or pivot mechanism 32 is disposed at a first end 34 of the fastener 22 and pivotally connects the base 28 to the locking arm 30. A locking mechanism 36 is disposed at a second end 38 of the fastener 22 that secures or locks the fastener 22 in a closed position. In other words, the base 28 has a hinge 32 that pivotally engages the locking arm 30 at one end, and the clasp or locking mechanism 36 that engages an opposite (free) end of the locking arm 30 to secure the locking arm 30 relative to the base 28. The hair clip 20, as seen in FIG. 2, is in an open position thereby providing a detailed view of the locking mechanism 36. The locking mechanism 36 includes a pair of locking arms 44 that are integrally formed with and extend upwardly from with the base 28. The locking arms 44 each include a button 46 disposed at the end thereof, and a hook 48 disposed between the button 46 and the base 28. The free end of the locking arm 30 includes a slot 40 that is defined by a pair of locking tabs 42 (FIG. 2). In operation, to close the fastener 22, the locking mechanism 36 is pressed towards the free end of the locking arm 30, thereby locking the fastener 22. Specifically, as the free end of the locking arm 30 is pressed against the locking mechanism 36, the hooks 48 are forced together by engagement with and deflection of the arms 44 into the slot 40 until the locking tabs 42 pass the hooks 48, at which time the hooks 48 engage the locking tabs 42 to retain the locking arm 30 in the closed position. To open the fastener 22, the user presses the buttons 46 inwardly toward each other until the hooks 48 disengage from the locking tabs 42 to release the locking arm 30. Once the buttons 46 are released, the arms 44 will return to their original position.
An operation of the hair clip 20 will be herein described as retaining a bundle of hair (not shown), but it should be understood that the hair clip 20 may be used to retain, hold, or be disposed on a variety of objects in a variety of ways. As best illustrated in FIGS. 2 and 3, a user may engage an open clip 20 with a bundle of hair, such that an inner spring surface 50 (FIG. 2) abuts a first portion of the bundle of hair (not shown). The user may then close the clip 20 by engaging an inner surface 52 of the locking arm 30 (FIG. 2) with a second portion of the bundle of hair (not shown), and engage the locking mechanism 36 with the free end of the locking arm 30, thereby closing the clip 20. As a result, the bundle of hair is retained in the clip 20. Additionally, the high friction or non-slip material of which the spring member 31 is constructed will aid in the retention of hair in the hair clip 20, as the high friction or non-slip material will provide addition gripping ability of the hair compared to previous constructions.
The above exemplary embodiment may be varied or altered to achieve and create similar, additional or alternative features. For example, even though the above exemplary embodiment is describing a certain type of hair clip, the sprit and scope of the invention covers other types of hair clips, such as other types of barrettes, snap clips, living hinge clips, etc. For example, barrettes or other hair clips currently on the market, could be altered by applying a gripping or friction member.
The gripping member for solid hair accessories, such as wood, plastic, or metal, can be achieved by coating the hair accessory with a vinyl or epoxy type product, lining or wrapping the product with a rubber or other gripping material including Velcro®, or by manufacturing a product that has two components (i.e. a two shot injection molding machine where a TPE coating is applied over a plastic part). The gripping member can be applied during the initial manufacturing step or in a secondary operation.
In the embodiment shown in FIGS. 4-6, a hair clip 120 includes a fastener 122 having a base 128 pivotally connected to a locking arm 130 via a hinge 132. In this exemplary embodiment, the spring member 131 is part of the locking arm 130 as opposed to the base 28 of the previous embodiment, and includes an insert or plug 154 disposed in an aperture 156 (FIG. 5) of the spring member 131. Additionally and/or alternatively, the insert 154 may be disposed on other components of the hair clip 120, such as base 128 or the locking arm 130, depending on the construction and placement of the spring member 131. The insert 154, as best seen in FIG. 5, includes an inner portion 158 for abutting the strands or bundle of hair, and a groove 160 for engaging the aperture 156. The insert 154 may be used to retrofit or update existing hair clips 120 having at least one aperture 156, with the insert 154 being press fit into the aperture 156.
The insert 154 may be designed in a variety of shapes and sizes and possess a variety of textures that can improve the holding power of the hair clip 120. The materials that may be used are “soft” such as natural rubber, neoprene, santoprene, TPE, silicone, nylon, etc. The processes that can produce these insert, plugs, or snap-over pieces 154 may be injection molded, extruded, stamped and casted. The insert 154 may also be designed to be a harder plastic insert possessing bumps, ridges, or any form of geometry to increase surface area for gripping.
In another exemplary embodiment, as illustrated in FIGS. 7 a-c, the clip 122 may include one or more inserts 154 that may be disposed generally parallel, perpendicular, and/or diagonal (not shown) to a length of the hair clip 120.
In another exemplary embodiment, illustrated in FIG. 8, a hair clip 220 includes one or more friction members 260 disposed on a base 238 of a fastener 222. In this exemplary embodiment, the base 238 includes a plurality of recesses, grooves or divots 262 oriented in a generally diagonal direction with respect to the length of the hair clip 220 in which the friction members 260 are disposed. The friction members 260 may, however, be disposed in any direction relative to the length of the hair clip 220. The manner in which the friction members 260 are affixed or connected to the fastener 222 may also vary greatly.
For example, in one embodiment, one or more portions of the fastener 222 may be dipped into a vat of liquid material that then cures to a soft, gripping material. Alternatively, the friction members 260 may be dripped onto one or more portions of the fastener 222. As a result, the fiction member(s) 260 may cover a majority of one or more of the components of the fastener 222 with a contiguous cover of the friction member 260. Additionally, as briefly disclosed above, the fastener 222 may include grooves, recesses, slots, or tabs to aid in securing the friction members 260 and/or to provide additional gripping power. As another alternative, the fastener 222 may be placed in an injection molding machine to undergo an over-molding process in which one or more of the components of the fastener 222 are over-molded with a friction member 260 or insert 154 such that the over-molded portion is non-removable.
In a further embodiment as illustrated in FIGS. 9-11, a fastener 322 shown without a shroud includes a sheath or cover 364. Specifically, as seen in FIG. 10, a base 328 of the fastener 322 includes the sheath 364 that surrounds a substantial portion of the base 328. In addition, the sheath 364 may include bumps 368, ridges, or any form of geometry to increase surface area for additional gripping strength. Alternatively, the sheath 364 may be disposed on a lower clip portion 330 or on a spring member (not shown). The sheath 364 may be manufactured separately and then slid or snapped onto the fastener 322 before final forming of the fastener 322 is complete. Alternatively, the sheath 364 may also be manufactured by placing the fastener 322 in an injection molding machine to undergo an over-molding process in which one or more of the components of the fastener 322 are over-molded with a friction member (TPE, silicone, etc.) before final forming of fastener 322 is complete.
In another exemplary embodiment as illustrated in FIG. 12, a fastener 422 includes a sheath 464 created by wrapping, coiling or otherwise disposing a band, tape, or other elongate frictional member 460 having a positive frictional property around one or more of a base 428 and a locking arm 430 of the fastener 422. The elongate frictional member 460 may be wrapped in a criss-cross, spiral, or other pattern, and may be affixed to the fastener 422 in several manners. For example, one or more portions of the frictional member 460 may be glued, melted, or otherwise adhered to the fastener 422. Additionally and/or alternatively, the frictional member 460 may be connected to itself such that, for example, a first and second end of the frictional member 460 are connected, thereby connecting the frictional member 460 to the fastener 422.
In another embodiment illustrated in FIG. 13, a hair fastener 522 is shown as a snap clip or contour clip 522, and includes a base 528 and an integral arm 530 that extends from the base 528 and is at least partially disposed on an opening of the base 528. The hair fastener 522 may be constructed from a plastic or metal material capable of providing the biasing force necessary to open and close the fastener 522. Specifically, the fastener 522 as illustrated in FIG. 13 is in an open position such that the base 528 has a convex shape relative to the integral arm 530. More specifically, in the open position, the base 528 has a convex shape such that a free end of the integral arm 530 is disposed apart from the base 528.
In closing the fastener 522, the user forces the base 528 from the convex shape to a concave shape, in essence snapping the fastener 522 from an open position to a closed position. In a closed position, the base 528 has a concave shape complementary to that of the integral arm 530, such that the free end of the integral arm 530 is disposed adjacent the base 528, thereby retaining the hair between the integral arm 530 and the base 528. In other words, the user forces the base 528 from the convex shape to a concave shape, in essence snapping the fastener 522 from an open position to a closed position. The fastener 522 may be dipped into a vinyl bath to produce a gripping surface on the entire fastener 522 or may be provided with an insert pad assembled into an aperture of the fastener 522 or portion of a positive friction member to prevent slippage of the hair. A soft touch paint may also be applied to cover one or more surfaces of fastener 522.
In a still further embodiment illustrated in FIG. 14, a hair fastener 622 includes a base 628 and an outwardly extending locking arm 630 having a living hinge 632 disposed between proximal and distal ends thereof. The fastener 622 in this embodiment may be constructed from a single molded plastic piece having a first end 634 and a second end 638. The living hinge 632 is disposed at the first end 634 of the fastener 622 and pivotally connects the base 628 to at least a portion of the locking arm 630. A locking mechanism 636 is disposed at the second end 638 of the fastener 622, and secures or locks the fastener 622 in a closed position, when the distal end of the locking arm 630 is folded about the hinge 632 and placed into contact with the locking mechanism 636. The fastener 622, as seen in FIG. 14, is in an open position, thereby providing a detailed view of the locking mechanism 636. The locking mechanism 636 is disposed near an end of the base 628 and comprising a post 644 that engages an aperture 640 disposed at the distal end of the locking arm 630. The clip 622 may be dipped into a vinyl bath to produce a gripping surface on the entire clip 622 or may be provided with a pad or portion of a positive friction member 654 to prevent slippage of the hair. Fastener 622 may further include an aperture (not shown) to allow for an insert to be assembled onto fastener 622 or over-molded with a resilient cushion material such as TPE, silicone, or the like.
In another embodiment, as illustrated in FIG. 15, a fastener 722 includes a first member or half 728 and a second member or half 730. The fastener 722 in this embodiment, may be constructed from one or more pieces of pliable material such as, leather, woven material, etc. A pivot or hinge 732 is disposed at a first end 734 of the fastener 722 and pivotally connects the first member 728 to the second member 730. A locking mechanism 736 is disposed at an opposing end of the fastener 722 and secures or locks the fastener 722 in a closed position. The locking mechanism 736 in this embodiment, includes a first magnet 736 a disposed near an end of the first member 728 and a second magnet (or metal piece) 736 b disposed near an end of the second member 730. The magnets 736 a and 736 b are positioned such that the magnetic attraction between them secures the first and second members 728, 730 together, as illustrated in FIG. 16. Specifically, the clip 722 may include pockets or openings disposed near the ends of the first member 728 and the second member 730, in which the magnets 736 a and 736 b may be placed. The magnetic locking mechanism 736 allows a one-handed actuation of the fastener 722, and allows the consumer to more closely adjust the fastener 722 to the amount of hair that is placed in the fastener 722, due to the lack of a positive locking mechanism. Alternatively, the magnetic locking mechanism 736 may be replaced by a snapping mechanism, such that a male portion of the snap mechanism is disposed on an inside surface of the first member 728 and a female portion of the snap mechanism is disposed on an inside surface of the second member 730.
While the present invention has been described with reference to specific examples, which are intended to be illustrative only and not to be limiting of the invention, it will be apparent to those of ordinary skill in the art that changes, additions or deletions may be made to the disclosed embodiments without departing from the spirit and scope of the invention.
