Hair comb and dual comb hair accessory having same

An improved hair comb for a dual comb hair accessory (11) or the like which has strand connections or terminations. The comb includes a spine (17) having a raised portion (19, 21, 23) that can advantageously be used to relocate or reorient strand connections to the comb or combs of the hair accessory relative to the plane of the comb, and that can provide a structure into or behind which strand connections, terminations and/or segments can be tucked. Preferably, the raised spine portions of the combs are constructed to form a raised cavity region (27) in the spine for receiving strand connections, terminations and/or segments.

BACKGROUND OF THE INVENTION

The present invention generally relates to hair accessories which employ hair combs and strands of material, typically elastic strands, which are attached to the spines of the hair combs. The invention more particularly relates to the combs used in such hair accessory products.

Hair accessory products are used to style and decorate a woman's hair. In one widely used type of hair accessory product, referred to herein as a “dual comb hair accessory,” elastic strands of material are attached to and interconnect the spines of two opposed combs. The opposed combs are pulled apart so that the elastic strands are stretched, and then the combs are folded under and inserted into the hair to retain the hair in a desired position. Often, the elastic strands, which can be parallel, braided, intertwined or crisscrossed, are beaded or fabric covered to provide a decorative element to the accessory.

Plastic combs are often used for dual comb hair accessory products. An example is found in U.S. Pat. No. 6,123,086, which discloses a dual comb hair accessory having plastic combs interconnected by fabric covered elastic bands. However, use of conventional plastic combs involves a number of difficulties. First, the spine of the comb is by necessity relatively wide in order to provide sufficient strength and thickness of material for the attachment openings for the accessory's elastic elements. The large spines create a relatively bulky comb, which is noticeable in the hair and which is not aesthetically pleasing. Further, when worn, attachment of the elastic strands to strand openings on the flat spines of the combs tends to lift the spine of the combs from the head, thereby creating stability problems. Still further, the connections of the elastics on the underside of the comb, such as knots or other forms of attachment, can create pressure points between the comb and the scalp, causing discomfort to the wearer. These connections can also cause the spine to perch up on the wearer's head, thereby exacerbating the stability problem. Still further the gathering of strand connections underneath the spine can sometimes stick out from underneath the spine, creating an unsightly look that detracts from the desired ornamental appearance of the accessory.

The present invention provides an improved hair comb that overcomes the problems associated with conventional plastic combs used with dual comb hair accessories. The improved hair comb of the invention offers greater stability for the hair accessory, and when worn, permits strand connections behind the spine to be displaced from areas where they can sometimes be seen and cause discomfort. The present invention also provides a comb having a relatively unobtrusive comb spine that is more aesthetically pleasing yet durable. Other advantages of the present invention will be readily apparent from the following specification and claims.

SUMMARY OF THE INVENTION

The invention is directed to a hair comb to which strands, and typically elastic strands, can be attached. The comb includes a spine having a raised portion that can advantageously be used to relocate and/or reorient strand connections (such as knots and/or attachment mechanisms and/or strand segments running behind the spine) relative to the plane of the comb, and that can provide a structure into or behind which such strand connections can be tucked. Preferably, the raised spine portion of the comb is constructed to form a raised cavity region in the spine for receiving the strand segments, connections or terminations.

In another aspect of the invention, a dual comb hair accessory is comprised of opposed combs, each of which has a raised spine, and strands interconnecting the combs. The strand segments, connections or terminations are tucked behind or into a cavity region in the raised spines of the opposed combs. Preferably, the strand openings are provided on the raised portion of the spines of the combs, such that strand-spine connections at the strand openings are elevated relative to the plane of the comb. From this elevated position, the pulling forces which are exerted on the combs by the tensioned strands when the combs are pulled apart are exerted from a higher location on the combs than is the case with conventional combs.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENT

Referring now to the drawings,FIGS. 1-4show a dual comb hair accessory11having a plurality of strands13extending between and connecting opposed combs15in a manner that allows the opposed combs to be folded underneath the strands, as best illustrated inFIGS. 2 and 4. The connecting strands are preferably fabricated of a stretchable elastic material, such that the opposed combs can be pulled apart against the stretching force of the elastic strands before the hair accessory is inserted into the hair. The elastic strands provide a restoring force that will hold the hair accessory in place. The strands can be made of an elastic filament or cord, or elastic bands. Preferably, the elastic strand or strands are made of an elastic material that has a 3-to-1 or more stretch capability; however, use of strands having a lesser stretch capability are possible. Suitably, elastic cord can be used that is made of rubber covered with a woven textile material that prevents hair from sticking to the rubber. Other elastic materials could be used such as latex, silicone or a polymer resin.

It will be understood that the parallel configuration of elastic strands shown inFIG. 3is for illustrative purposes only, and that other strand configurations could be used to interconnect the combs, including crisscrossed strands, partially crisscrossed strands, braided, looped, intertwined and strands of other types, materials, and shapes. Also, the strands can be decorated with various decorative elements, such as beads of various sizes and shapes, to provide an aesthetic quality to the hair accessory, or could be used without any decorative elements. Still further, it is contemplated a single comb in accordance with the invention could be used with elastic strands that form loops for use as a ponytail holder or the like.

As hereinafter described, the strands13of the dual comb accessory11are attached to the spines of the combs by various forms of strand connections. As further hereinafter described, this strand connections can be made by knotting or tying the ends of the strands or by attachment mechanisms that secure the ends of the strands in place on the combs.FIGS. 1-2show an attachment mechanism in the form of terminal pins in the form of T-pins14that are secured to the ends of the strands such that the pins can be turned sidewise relative to the strands. T-pins14are suitably small tubes that can be slit longitudinally so that the ends of the strands can be inserted in the tube slits and tubes crimped onto the strand ends. It will be understood that attachment mechanisms other than the illustrated T-pin could be used. Examples of alternative attachment mechanisms will be described later in this specification.

Various embodiments of the novel comb of the invention are illustrated in greater detail inFIGS. 5-17. Each of these embodiments is characterized by a novel construction that allows the connecting strands13of the hair accessory11to be easily attached to the comb, and that allows the strand connections (knots, attachment mechanisms and/or strand segments running behind the spine) to be captured within or behind the spine above the combs radius of curvature, denoted by the letter R inFIG. 8.

FIGS. 5A-9illustrate a preferred embodiment of the hair accessory comb of the invention. In these figures, the hair comb15includes a laterally extending spine17having raised portion comprised of a raised front edge wall19forming the leading edge of the spine, a top wall portion21extending rearward from the front edge wall, and a trailing edge wall23forming the trailing edge of the spine and terminating at a bottom edge25. Walls19,21, and23are seen to form a raised cavity region27on the underside29of the spine into which connections can be tucked. A plurality of comb teeth29extend longitudinally from the front edge wall of the comp's spine17, preferably along a curvature R that allows the combs to more or less conform to the curvature of the head of the wearer of the dual hair comb accessory. Preferably, the bottom edge25of the spine's trailing edge wall will extend downwardly a sufficient distance so that it also lies, or approximately lies, on the curvature R so that the comb bottom surfaces all follow the curvature of the wearer's head. However, this trailing edge wall could be of other lengths, preferably a shorter length so that the bottom edge25does not itself create a pressure point on the wear's scalp. (Indeed, as later described, the trailing edge could be eliminated altogether.) Also, the top wall portion21could be flat or rounded, or could even be a point formed by intersecting leading and trailing edge walls.

Because of the curvature of the comb, opposed combs15of the dual comb hair accessory11shown inFIGS. 1 and 2, when worn, will lie more or less flat against the scalp with the elastic strands13, which stretch across the hair, pulling on the combs to hold them in place.

To connect the strands of material to the spine of comb15, such as the elastic strands13of the dual hair comb accessory11shown inFIGS. 1 and 2, the spine is provided with a series of strand openings31through which the connecting strands can be threaded. Preferably, these strand openings are provided, at least in part, in the front edge wall of the spine where they are raised above the level of the comb teeth and are oriented (at least in part) at an angle that is pitched up from the plane of the comb. The raised and pitched-up strand openings advantageously raises the strands relative to the plane of the combs and changes the way the tension exerted by the stretched elastic strands pull on the combs. Instead of pulling on a flat spine along the plane of the comb, the strands exert a pulling force from an elevated position. They also pull against a raised wall which inclined upwardly relative to the curved plane of the comb.

The above-described raised spine construction of comb15has still further advantages. In conventional plastic hair combs, the spine is substantially flat and prone to breakage. To resist breakage the comb spine is normally made to be relatively wide thereby producing a relatively bulky looking comb. The raised spine can provide a U-shaped, or partial U-shape spine construction having relatively high structural integrity and allows a narrower and thus relatively unobtrusive spine to be used without sacrificing durability. Also, the raised cavity region27on the underside of the spine allows strand connections, such as knots or attachment mechanisms as hereinafter described, to be tucked away in the spinal structure where they cannot escape or be seen.

The number of strand openings31in the comb spine15can vary depending on the intended use of the comb or the desired design of a dual comb hair accessory in which the comb is used. Suitably there would be two or more openings for entry points for two or more connecting strands or strand segments threaded between opposed combs (or to allow two ends of a single strand to connect to the comb). Preferably, these openings would be evenly distributed across the length of the spine to provide a balanced hair accessory, however, an unbalanced strand distribution would be possible and considered within the scope of the invention. A single opening would also be possible, including an elongated opening or openings extending along the length of the spine. It is also contemplated that openings of varied sizes can be used.

In the embodiment illustrated inFIG. 5A-9, strand openings31are seen to be provided between the endmost comb teeth27aand their adjacent teeth27band then evenly distributed between successive pairs of comb teeth27cand27dseparated by a single comb tooth27e,27fand27g, with comb tooth27gbeing the center tooth of the comb. Adjacent comb teeth are seen to form short and long comb teeth separation channels33,35, with the strand opening31positioned behind the short separation channels33, and with the longer separation channels35extending up into the front edge wall of the spine of the comb between the strand openings. Because hair will flow into the extended length of these longer channels—which can for example extend into the spine by about ¼ inch—the longer channels will permit secure placement of the hair accessory in the hair with greater stability and comfort.

In the illustrated embodiment, a spacing for the strand openings on the spine is selected to provide two long channels between each strand opening and its associated short channel, resulting in a comb having a high percentage of long channels and a good distribution of points on the spine through which connecting strands can be threaded. Also, the distribution produces a short channel next to each of the outside teeth27aof the comb, which are preferably wider than the comb's interior teeth27b-g. It is believed that providing relatively wide outside teeth along with a channel distribution that places the short channel next to the wider outside teeth of the comb enhances the stability of the comb in the hair.

With further reference toFIGS. 5A-9, when viewed in side elevation it is seen that the thickness of each of the comb teeth, as denoted by the letter T inFIG. 9, is relatively uniform over the length of the comb and that the comb teeth terminate at rounded ends37. When seen in from the top plan view, the interior long edges39of the comb teeth are seen to taper inwardly as you move toward the spine of the comb. Thus, the comb teeth are widest at the base of the teeth and narrow at the rounded ends so that the rounded ends are relatively far apart. By keeping the ends of the comb teeth far apart, the teeth will tend to flow through the hair more uniformly.

While the above-described shape and spacing characteristics of the teeth of the comb of the invention are preferred and have particular advantages, it will be understood that the invention is not limited to combs having comb teeth with these characteristics. Hair combs having a raised spine in accordance with the invention could be provided with comb teeth of other shapes and having other spacing characteristics, such as parallel teeth having closely spaced tips or staggered rows of teeth, and could have a greater or fewer number of teeth than shown. The ends of the teeth could also be pointed, flat, square or coated with another material such as rubber or silicone.

The comb of the invention can be readily and inexpensively fabricated as a molded plastic part using plastics found in conventional hair combs. It would most suitably be fabricated of a durable plastic, such as PET, ABS plastic or polystyrene, but could be made of other materials. For example, it is contemplated that the combs could be made of stamped metal, or could have a metal spine and wire loop teeth. The dimensions of the comb can vary depending on its intended application. Generally, it is contemplated that combs in accordance with the invention can be provided in different sizes, with the width of the comb, denoted by the letter W inFIG. 6, suitably ranging 1½ to 3½ inches, and the length of the spine, denoted by “L” inFIG. 6, suitably ranging from 1 to 4½ inches. A suitable comb thickness (thickness “T” inFIG. 9) would suitably be in the range of 0.1 inches. In the embodiment shown inFIGS. 5A-9, this thickness is seen to be substantially uniform over the entire comb from the ends of the teeth to the bottom edge of the trailing edge wall of the spine. It will be understood that combs having dimensions other than indicated above are possible and within the scope of the invention.

As above mentioned, strands of material, typically elastic strands, can be attached to the spine of the comb in various ways. Desired strand configurations could be accomplished using a single strand by weaving the single strand between the desired strand openings of the comb or combs and attaching the end points of the strands at the comb spine or spines, such as by knotting or via an attachment mechanism. Or this could be accomplished using multiple strands.

InFIGS. 1 and 2the attachment of multiple strands13to combs15to form the dual comb hair accessory11is shown and is accomplished by simply holding the ends of the strands and pushing the terminal T-pins14through the desired strand openings31in the raised portion of the comb's spine17, as denoted by the arrow A inFIG. 1, and pulling the strand end back so that the T-pin lodges in a rotated position against the back of the opening, where it will be tucked up into the raised cavity region27of the raised spine27of the comb, as shown inFIG. 2. If desired, the end of the elastic strand can be threaded down through one strand opening, run along the underside of the spine, and then threaded up through another strand opening on the same comb, whereupon it can be stretched to the opposed comb for threading through a strand opening in the opposed comb. This back-and-forth threading process can be continued until being terminated by simply allowing the T-pin on the threaded end to rotate behind the last strand opening through which the strand end is threaded. During this process, the strands can be threaded with beads or other decorative elements for form a decorative pattern of woven or straight strands between the combs.

Referring toFIGS. 10A-14, a hair comb is shown having an alternative design for the raised spine of the comb. Here, the spine43of hair comb41has a raised portion comprising a raised front edge wall45that rises up from a flat front shoulder portion46that forms the leading edge of the spine, and a bent over top wall portion47. Unlike the embodiment shown inFIGS. 5A-9, the spine of this version of the comb has no trailing edge wall, and thus produces a raised cavity49on the comb's underside51that is open in the back. A plurality or elongated strand openings53extend from the spine's leading shoulder portion up into the raised front edge wall with one strand opening being provided behind each separation channel55for the longitudinal comb teeth57. In this case the strand openings53through which elastic strands can be threaded are virtual extensions of separation channels55and provide a greater number of strand connection points for the strands. As in the previously described embodiment, the raised cavity region of the spine structure will accommodate the tied or fastened ends of connecting strands and strand segments situated beneath the spin. Also, as in the prior embodiment, the strand openings are elevated relative to the curved plane of the comb, thus providing for elevated strand connections for improved stability.

In the embodiment of the invention shown inFIG. 15, the hair comb59is similar to the hair comb41shown inFIGS. 10A-14, except the strand openings61are located on the top wall63of the comb's spine65. This location of the strand openings elevates the connection points for the strands to the top of the raised spine, but does not have the advantage of producing a pulling force on a structure part of the spine that is inclined relative to the curved plane of the comb.

FIG. 16illustrates a hair comb (comb67) similar to the embodiment shown inFIGS. 10A-14, including a similar placement of the strand openings on the front edge wall69of the raised spine71, but with fewer strand openings. In this embodiment the strand openings72are seen to be less elongated, and unlike the version shown inFIGS. 10A-14, they do not extend into the spine's front shoulder portion73.

Yet another possible embodiment of the hair comb of the invention is shown inFIG. 17. Here, the raised spine75of hair comb77is similar to the open raised spines of the embodiments disclosed inFIGS. 10A-16, except the raised portion79of the spine contains no strand openings. Rather, in this embodiment, the strand openings79are placed in front of the raised portion of the spine on the spine's front shoulder portion81. This location of the strand openings relative to the raised portion of the spine is considered to be the least desirable location since it would produce a dual comb hair accessory that would be less stable when worn. Nonetheless, the raised portion of the spine would allow strand ties or fastening mechanisms and segments of strands running along the spine to be tucked up into the raised cavity on the underside of the spine.

It will be appreciated that other version of the hair comb of the invention are possible which are not specifically illustrated and described herein. For example, the raised portion of the spine could be comprised of a leading or raised edge wall only, without a bent over top wall portion or a trailing edge wall. In such an embodiment, strand openings could be provided in the raised edge wall thereby advantageously elevating the strand openings and connection points for the strands. Strand knots or attachment mechanisms would be tucked behind the raised edge wall and also raised so as to prevent pressure points from being produced by the connections on the wearer's head. A cavity region could be provided on the back of such a raised edge wall into which the strand connections could be tucked.

In another possible embodiment (not shown), the raised portion of the spine could be two or more raised spinal sections which are not continuous along the length of the spine. This would create gaps, such as flat portions of the spine, between the raised spinal sections. The raised spinal sections would in turn create non-continuous raised cavity portions on the underside of the spine for receiving stand terminations or connections.

FIGS. 18-20illustrate alternative attachment mechanisms for the securing the ends of the strands of the dual comb hair accessory11. InFIGS. 18,19, and19A, the attachment mechanisms are provided on the form of spine cavity plugs101. The plugs101, which are suitably made of a soft rubber or plastic material, preferably have a half round shape, and are sized such that the plug's curved side103fits snugly in the raised cavity region27on the underside of the spines17of combs15. When a plug101is pressed by hand into the spine cavity27of one of the combs15, the plug's flat side105will remain tucked within the cavity27so that the plug does not protrude from the underside of the comb and press on the wearer's scalp. The length and width of the plug should be large enough such that, when pressed into the spine cavity, it will be retained in the cavity until it is forced or “popped” out of the cavity by a prying force exerted by the user, such as by the user's finger.

As best seen inFIG. 19A, the plugs101can be attached to the ends of the strands13by threading the ends of the strands through a hole107that extends the length of the plug, and then knotting the strand ends. This is done after the strands are threaded through the comb's strand openings in a desired strand configuration, for example, in a parallel or crisscross configuration. Once the spine cavity plugs are installed on the strand ends and the strand ends knotted, the plugs are slid firmly up against the strand's knotted ends. Preferably, one end to the plug hole107is enlarged to form a recess109. Thus, by orienting the plug so that its recess end faces the knot109made at the end of the strand, the knot can be pulled into the recess. This not only hides the knot, it also prevents the knot from hanging outside of the plug where it might lodge between the scalp and the plug, or between the scalp and the underside of the comb.

It is noted that, instead of threading the strand ends through the plugs101, the plugs could simply be pressed into the spine cavity27over the ends of the strand to keep the strand ends tucked into the spine cavity. Preferably, the strand ends would be knotted before doing this to prevent the strands from pulling out of the spine.

FIG. 20shows yet another attachment mechanism for the strands of the dual comb hair accessory11. In this embodiment, the ends of the strands13are provided with strand end connectors that can be connected together behind the spines of the combs15. One end of the strands has a female connector element111and the other end has a male connector element113, and at least one and preferably both of the connector elements have a sufficiently small profile that allows the connector elements to be inserted through the combs' strand openings31. The male connector113has a base114, which has an opening (not shown) for receiving the strand ends, and to which strand ends can be attached such as by crimping the base onto the strand ends. The female connector element similarly has a base end112for attachment of this connector element to the other ends of the strands. The male and female connectors are designed such that the user can insert the projecting end of the male connector into the female connector without male connector pulling out of the female connector during use, but such that the connectors can be later separated by the user. In the version of the connector shown inFIG. 20, the male connector is provided with a metal barbed end116(with metal barbs115) that fits into a sheath end117of the female connector element, which is suitably fabricated of a soft material such as latex. The barbs of the male connector will stick in the soft sheath with enough holding force to keep the ends joined during use. It will be understood that connectors types and configurations other than illustrated inFIG. 20could be used, including snap connectors and hook and loop fastener such as Velcro®.

Once the strand ends are connected together behind the spine of one of the combs as shown by the arrow inFIG. 20, the strand connections can tucked up into the cavity27formed on the underside of the spine. Thus, the strand end connections will not protrude below the plane of the comb where it could press against the wearer's scalp. It will be appreciated that the strand end connectors can be used to the attach strand ends of both multiple short strands behind each of the comb as shown inFIG. 20, or they can be used to attach the ends of one or a few longer strands that are threaded back and forth between the combs. For example, a relatively long single elastic strand having complimentary connectors at each end could be threaded back and forth between the combs' strand openings such that the two connector ends both emerge in the cavity region27behind the raised spine of the same comb. (Again, at least one of the connectors must be sized to fit through the strand openings of the combs.) Here they can be joined together to secure the strand ends, and the single strand connection can be tucked into spinal cavity of the comb behind which the connection is made. The raised cavity region on the underside of the spine allows the segments of the single strand that run behind the comb spines when it is threaded back-and-forth between the combs to be tucked into the spine.

While the present invention has been described in considerable detail in the forgoing specification and the accompanying, it shall be understood that it is not intended that the invention be limited to such detail, except as necessitated by the following claims.
