2. Description of Related Art
Existing hair treatment devices include a category of devices that crimp hair. These crimping devices, known as crimping irons or crimpers, impart a series of bends or creases to the hair. There are two uses of such crimping devices. A first use, and a common use, is to impart a visible crimp pattern to the top layer of the hair as a distinct hairstyle, this is known as a crimped hairstyle and this process is known as crimping. A second use, described in U.S. Pat. No. 7,992,578, is to use a crimping device to create the appearance of volume to a person's hair. This is done by applying the crimping device to an under layer of the hair. An under layer of hair is a layer of hair that is covered by an upper layer of hair and has at least a portion that is an interior hair layer that is not visible in a hair style because an upper layer of hair rests on top and hides it from view. In this method of use the under layer of hair is crimped. This causes the upper layer of hair to be lifted and held away from the head, creating the appearance of greater hair volume. This is because the outer layer of hair rests on the under layer further away from the head and scalp than it would have rested when the under layer was not crimped. Thus the upper layer is lifted and creates the appearance of more hair volume. This lifting application of the device has been accomplished heretofore by re-purposing the first use of the crimping device of creating a distinct pattern in the visible hair and using the same crimping device on an under layer of hair and not on the upper visible layer of hair.
There are many drawbacks to using a known crimping device in a lifting application because the crimping device is not specifically designed for use in a lifting application. A crimping application requires that the crimping device impart a distinct crimped pattern to the hair, which does, as a secondary effect, create somewhat greater volume in the hair. However, a volumizing application requires the creation of a firm support structure in the under layer of hair that can be sustained while supporting the upper layer of hair, giving the appearance of significantly greater hair volume, and that little or no discernible pattern or texture be visible, thereby leaving the basic hair style unchanged. Current hair treatment devices are not specifically designed for lifting and volumizing and do not meet these requirements.
In particular, the saw-tooth ridge design of crimping devices, such as in U.S. Pat. No. 7,992,578, does not meet these requirements for volumizing. These crimping devices employ a single row of long columnar, saw-tooth-shaped ridges on heated mating and interlocking plates, which are embedded in a handheld device that is clamped briefly on the hair. The ridges in these devices extend the entire length of the heated interlocking plates. The ridges run parallel to the long axis of the device.
There are many problems with the known crimping device with the arrangement of saw-tooth ridges in a hair-lifting or volumizing application including:
The arrangement of saw-tooth ridges leaves a noticeable, undesirable crimped pattern in the under layer of hair that shows through to the upper layers. The person's hair then appears visibly crimped, which is not the objective of users seeking to add volume and lift to hair without changing the hairstyle. Crimped hair shows through to the upper layers because the saw-tooth ridges found in existing crimping devices creates a distinct and regular pattern in the hair consisting of a series of sharp, long, accordion pleats or folds. These pleats which are as long as the length of the plates of the device are obvious in the hairstyle and tend to poke through to its upper layers. Further, any hair treatment device having ridges of any shape leaves a distinct pattern in the hair when used in a volumizing application due to the length and regularity of the folds that are created in the hair. Since a goal of a hair treatment device used in a volumizing application is to create lift and volume without creating a visibly crimped hairstyle, any use of ridges, having a saw-tooth or other profile, in such a device is undesirable.
A second problem with the saw-tooth-ridged pattern in crimping devices is that it is not able to create a firm support structure in the lower layers of hair capable of supporting the upper hair layers when used in a volumizing application. This is because the sharp, saw-tooth-shaped ridges create a series of sharp, accordion pleats in the hair that unfold or collapse under the weight of the upper hair layers resting on them and no longer aid in volumizing the hair. As one crimped pleat or fold of hair loses structure by folding or collapsing, the load of the portion of the upper layer of hair that the pleat was supporting is transferred to the adjacent crimped pleats of hair, which in turn are now weighted with more weight than they can support, leading to collapse of all pleats of the hair treated by the device in a domino, cascading fashion. Thus, structural stability is not stable in a volumizing application done with a crimping device having saw-tooth ridges.
A third problem with existing crimping devices, such as found in U.S. Pat. No. 7,992,578, is that the ridge height is not adequate to lift the hair significantly up and away from the head and scalp, in order to create the appearance of substantially greater hair volume.
A fourth problem with prior art devices is the undesirable appearance of frizzy hair from the crimped under layer poking through to the upper layers of hair, caused by the use of closely-spaced, jagged, saw-tooth ridges. Frizzy hair appears dull, kinky, and unhealthy.
A hair volumizing device is designed specifically for adding lift or volume to any hairstyle. The device comprises two arms with heated interlocking plates that employ interlocking two dimensional arrays of individual treatment elements with alternating spaces. The individual treatment element design and the two-dimensional array pattern provide substantial lift and holding strength. The individual treatment elements of the volumizing device transforms the under layer of hair of a person into a matrix that can support the outer or upper visible layer of hair to create volume. The various embodiments also minimize any discernible pattern left in the hair.

A hair treatment device is optimized for lifting and volumizing hair. The volumizing device leaves little or no visible pattern or frizz in the hair and creates significantly greater and longer lasting volume in the hair. In an embodiment, these benefits are achieved through a design that employs arrays of outwardly projecting individual treatment elements arranged in a two-dimensional array pattern, such as a checkerboard or waffle pattern, instead of long, regular ridged, parallel treatment elements. The volumizing device may be for use by end users on their own hair as well as users on the hair of others, such as in salons by stylists and hair technicians.
The hair volumizing device allows users to impart significant volume or lift to hair by creating a three-dimensional matrix of hair in the under layers of the hair that serves to lift portions of the upper layers of the hair away from the head, creating the appearance of greater hair volume, without creating a clearly visible pattern in the hair. An under layer of hair is a portion of hair that is not visible in a hairstyle because it is located beneath the upper layers of hair that comprise the hair visible to others in a hairstyle. To separate an under layer from the upper visible layer of hair, a comb may be used to part the hair slightly below the point where the user typically parts the hair. The upper hair is separated and hair clips may be used to keep it out of the way while the under layer is being treated. The selected under layer of hair, is then treated with the volumizing device. This process can be repeated all over the head in order to lift hair away from the scalp, giving the appearance of greater hair volume. Users may treat only the portion of hair closest to where it leaves the scalp or they may additionally treat hair as far down the hair shaft as they desire.
A volumizing sub-structure in the under layers of the hair is created by clamping the hair between the interlocking plates of the volumizing device, which are made up of arrays of outwardly projecting individual treatment elements. The plates are heated and briefly clamped on the under layers of hair in order to create structural support for the upper layers.
In an embodiment, the interlocking plates may have a long axis in the direction of the length of the arms and a short axis in the direction of the width of the arms. Either or both of the interlocking plates may be heated by a heating element located within the arm. In an embodiment, the heating element may heat an interlocking plate by any conventional heating method including, for example, electrical resistance, induction, infrared, combustion, or steam. The heating element may heat an interlocking plate to an operating temperature in a range of about 250° F. to about 430° F. The temperature, as well as an on/off function, in some embodiments, may be controlled by an analog or digital circuit located, for example, within an arm of the device. In an embodiment, the device may be powered by an internal power supply, such as a battery. In an embodiment, the device may be powered by an external source through, for example, a power cord 9. Section A-A of
In an embodiment, the interlocking plates may have a complementary design such that, when the ends of the arms at which they are located are clamped together, the interlocking plates interlock with each other, as shown in
In an embodiment, each interlocking plate may include, for example, a two-dimensional array of separated individual treatment elements 10 separated on all sides by spaces 11. The embodiments of
When the heated plates clamp an under layer of hair, the hair is bent and formed by the heated plates to create a matrix of piers which serve to support the upper visible layer of hair and hold it away from the head, thus creating the appearance of greater hair volume. The hair treated by the device takes the shape of the treatment elements.
The array of alternating gap and treatment element design not only creates a strong support structure in the lower layers of hair, but it also does this without creating a clear pattern that is visible in the upper layer as is the case when using conventional crimping devices. This is because each treatment element creates a firm support pier in the hair that alternates with surrounding recessed piers, thus breaking up and obscuring any clear pattern of folds in the hair. This is in sharp contrast to the long, accordion pleat folds left in the hair by the long ridges of known crimping devices, which leave a clear pleated or crimped pattern that is visible in the upper layers of hair.
In embodiments shown in
When the plates are clamped together, as shown in
In addition to the treatment element configuration shown in the embodiment of
Non-rectilinear designs, such as those shown in
In embodiments, the treatment elements may be arranged in a variety of patterns. These arrangements may include rows and columns not parallel to either the long or short axes of the interlocking plate. Further, in some embodiments rows or columns of treatment elements may not be parallel to other rows or columns of treatment elements and may not be in a symmetrical pattern of rows and columns. In some embodiments the treatment elements may assume a spiral pattern, as shown in
The sides 12 of the individual treatment elements shown in the embodiment of
As shown in
In some embodiments the interlocking plates may be flat and rectangular, as shown in the embodiment in
In some embodiments, the overall device, including the arms and the interlocking plates may be straight and in some embodiments the overall device, or components thereof, may be curved, including, for example, along the long or short axes of the arms. In an embodiment, a curved volumizing device is curved to be better adapted to reach the back of the head more easily or to match the curvature of the head. In some embodiments, the overall device is made of smaller components to suit travel applications. In some embodiments, the travel version may have as few as two columns of individual separate treatment elements in any of the above described patterns.
In some embodiments, the construction of the interlocking plate may be made from ceramic or metal, including, for example, aluminum, aluminum alloys, copper, steel, iron, zinc and nickel alloys. In some embodiments, the metals may be coated with various materials, including, for example, silicone, anodized metal, TEFLON, ceramics, including, for example, tourmaline and titanium-infused ceramics or some combination thereof. In some embodiments, the treatment elements may have both thermally conductive and insulating layers and may contain materials designed to create friction to help hold the hair in place during treatment. Fabrication of the interlocking plates and treatment elements is done with any manufacturing method, including, for example, die casting, mold casting, extrusion, milling, drawing, laser cutting, and other metal forming and fabrication methods.
Referring now to the operation of a volumizing device such as that of the embodiment shown in
When a lower layer of hair is clamped between the heated plates of the device as shown in
By virtue of a checkerboard-like three-dimensional alternating treatment element pattern, portions of hair that are folded along a given row serve to support the neighboring hair portions in adjacent rows that are folded in the opposite direction. These alternating hair folds may create a strong foundation of support due to a grid of flat topped piers that are more stable and less likely than hair treated with columnar treatment elements, found in crimping devices, to collapse in a domino cascading fashion. This system also minimizes the spans between piers, so that the upper or outer layer of hair is better supported. This individual treatment element arrangement creates a more laterally stable platform to hold the upper hair up and away from the head or scalp, thereby adding the volume desired and holding it for long periods of time.
This alternating treatment element checkerboard design may provide such support without leaving a distinct visible pattern in the hair, due to the individual, flat-topped treatment elements and their alternating arrangement on the interlocking plates. Because each treatment element alternates with gaps on all sides, any clear pattern of folding in the hair created by each raised treatment element is broken up and obscured by the adjacent gaps between the treatment elements, especially when concealed beneath an upper layer of hair not treated by the volumizing device. This is in contrast to the long, sharp-peaked, accordion pleated folds left in the hair by the long, saw-tooth ridges of a crimping device, which leave a clear pleated or crimped pattern that is clearly visible in the upper layers of hair.
Additionally, the device creates volume and lift without creating undesired frizz in the lower layers that protrudes into the upper visible layers. When a segment of hair is placed over the entire active surface of the interlocking plate, and clamped briefly between two interlocking plates, a strong three-dimensional support system is created in the lower layer of treated hair that supports the upper visible layer, while the outer or upper hair layer remains untreated. This process can be repeated as far down the hair shaft as desired, thereby building volume on the top and on the sides of the head for a long-haired user. It can also be repeated in an under layer close to the scalp, over the entire head of hair, adding volume in the back of the head.
In summary, these plates impart to the hair a foundation of strong support designed to create, lift and add volume in hair, while minimizing a visible pattern in the hair and without creating undesired frizz.
