Description

Hair volumizing appliance

FIELD OF THE INVENTION

The invention relates to the field of hair styling appliances and more particularly to appliances for volumizing hair.

BACKGROUND OF THE INVENTION

Traditionally, the volume of hair is increased by introducing curls in the hair. In the beginning, hair curling clamps were used for that purpose, as e.g. described in

US2115229. A more modern appliance for volumizing hair is a crimper. An example of a crimper is shown in prior art publication US2004089317.

A problem with the known volumizing appliances is that they are not designed to create more volume in sleek hair without introducing curls. Volumizing sleek hair is one of the main challenges in current hair styling, both in the professional as in the domestic domain.

It is an object of the present invention to solve this problem and provide an appliance for volumizing sleek hair.

SUMMARY OF THE INVENTION

According to one aspect, the invention provides a hair volumizing appliance for increasing a hair volume near a person's scalp. The appliance comprises an insertion member to be inserted between the scalp and the hair when in use, wherein the insertion member comprises an unheated, scalp facing part to be positioned adjacent to the scalp when in use, and a convex shaped hair supporting part supporting the hair when in use. The hair supporting part comprises at least one heating zone arranged on a side facing away from the scalp facing part, the convex shaped part being in contact with the hair when heated, so as to cause a bending of the hair near the root, thereby increasing the volume of the hair near the scalp.

An advantage of this configuration may be that volume may be created in sleek hair without introducing curls. According to another aspect, the invention provides a hair volumizing appliance, wherein the scalp facing part and the hair supporting part are provided on a scalp facing member and a hair supporting member respectively. The scalp facing member and the hair supporting member are adjustably connected, the appliance further comprises an adjustment mechanism to adjust a distance between the scalp facing member and the hair supporting member, so as to vary the increase of volume in the hair.

It may be an advantage of this configuration that the increase of volume may be varied by varying the distance between the scalp facing member and the hair supporting member.

According to yet another aspect, the invention provides a hair volumizing appliance, wherein the heating element is a thermal electric cooler (TEC) and wherein the cold side of the thermal electric heater is positioned in thermal contact with the unheated scalp facing part and the hot side of the thermal electric heater is positioned in thermal contact with the at least one heating zone of the hair supporting part.

The use of a TEC may have the advantage that the hair volumizing appliance may be designed in a particularly compact and an energy-efficient way.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 2 is a second embodiment of a hair volumizing appliance according to the present invention.

FIG. 3 shows a front view of the second embodiment as shown in FIG. 2 in a substantially closed position (FIG. 3A) and in an open position (FIG. 3B) when in use.

DESCRIPTION OF THE EMBODIMENTS

FIG. IA shows an embodiment of a hair volumizing appliance 1 for increasing a hair volume near a person's scalp according to the present invention. The appliance comprises an insertion member 2 to be inserted between the scalp 7 and the hair 8 when in use. The scalp 7 and the hair 8 are best seen in FIG. IB. In this application, the term hair is broadly used and includes e.g. locks of hair. The insertion member 2 comprises an unheated scalp facing part 3 to be positioned adjacent to the scalp 7 when in use, and a convex shaped, hair supporting part 4 supporting the hair 8 when in use. The hair supporting part 4 comprises at least one heating zone 5 arranged on a side facing away from the scalp facing part 3. The contact with the at least one heating zone on the convex shaped hair supporting part causes the hair to be bent. The at least one heating zone may be heated when in contact with the hair. The at least one heating zone may also be pre-heated before being inserted into the hair.

Typical dimensions of the insertion member 2 are a width 21 of 12 - 20 millimeters, a height 22 of 10 - 20 millimeters and a length 23 of 150 millimeters.

When in use, the convex shaped, hair supporting part 4 supports the hair 8 and the hair 8 is in contact with an also convexly shaped heating zone 5 provided on the hair supporting part 4. Thus, the hair 8 may be bent to increase the volume in the hair. In FIG. IB, a front view of the embodiment shown in FIG. IA when in use, seen in the direction of arrow 6 it is shown that by using a substantially flat scalp facing part 3, the scalp facing part 3 and also the convex shaped hair supporting part 4, may be positioned near or on the scalp 7. Thus, the hair 8 may be bent near the root 9 of the hair 8 to increase the volume near the scalp 7 without curling the hair 8.

Preferably, the convex shaped hair supporting part 4 has a substantially semi circular shape, however variants on the semi circular shape may be possible. In one particular variant, which is best seen in FIG. 2, the semi circle is flattened on the sides and on the top. Depending on the amount of flattening, this variant may even approach a semi square.

In one embodiment, the convex shaped hair supporting part 4 comprises a base with a convex shaped hair supporting element on top of the base, wherein the convex shaped hair supporting element is removable attached to the base. In this configuration, different convex shaped supporting elements may be attached to the base depending on the desired volumizing effect and depending on the type of hair 8. The convex shaped elements are preferably made of ceramic material, to avoid harming the hair 8.

In the embodiment shown in FIG. 1, the scalp facing part 3 is unheated in a passive way. In alternative embodiments, the scalp facing part 3 may be actively cooled, e.g. by using a heat sink like a copper rod, a fluid streaming along the inner side of the scalp facing part 3 or air blowing through the scalp facing part 3.

In this embodiment, the temperature of the heating zone 5 may be 15O⁰C. Depending on the quality of the hair 8 and the desired styling effect the temperature of the heating zone 5 may vary between 8O⁰C and 300⁰C. Preferably the heating element has a controllable heating rate to choose the temperature depending on e.g. the thickness and sensitivity of the hair 8.

In the embodiment from FIG. 1, wherein no active cooling of the unheated scalp facing part 3 is applied, the unheated scalp facing part 3 and the heating zone 5 of the hair supporting part 4 may be separated by an insulating member (not shown), so as to avoid a negative impact of the heating zone 5 on the unheated scalp facing part 3 and vice- versa.

In this embodiment, the hair volumizing appliance 1 comprises a heating element configured for heating the heating zone 5 of the hair supporting part 4. In other embodiments, the hair volumizing appliance 1 may be a top-piece or and end-piece for a multi functional hair styling body. In that case, the body comprises the heating element and several top- or end-pieces may be connected to the body, e.g. a piece for curling straight hair 8, a piece for straitening curled hair 8 or a piece for volumizing straight hair 8 without curling.

In one embodiment, the heating element is a thermal electric cooler (TEC), based on the Peltier effect. A TEC usually has a cold and a hot side. In this embodiment, the cold side of the TEC is positioned in thermal contact with the unheated scalp facing part 3 and the hot side of the TEC is in thermal contact with the heating zone 5 of the hair supporting part 4. The use of a TEC may result in a particularly compact hair styling appliance and an energy- efficient design. Besides, a TEC permits for controllable heating and cooling rates, if wished. They may be provided in various sizes and with various maximum temperature differences.

Also in other embodiments of the hair volumizing appliance, the heating element may comprise a Peltier element. A Peltier element may easily be integrated into a hair styling appliance due to its relatively small size and weight. Besides, Peltier elements may be dimensioned to allow for mains operation or for battery operation.

An alternative way of heating the hair 8 is by emitting infra-red light between 6000 and 40000 nanometers. An advantage of using infra-red light of this wavelength range is that it may not harm the hair 8. Instead, it may even have a protective function by letting the inner organization of the hair 8 get more nourished.

In another embodiment of the hair volumizing appliance 101 according to the present invention as shown in FIG. 2, the scalp facing part 3 and the hair supporting part 4 are provided on a scalp facing member 10 and a hair supporting member 11 respectively. The scalp facing member 10 and the hair supporting member 11 are adjustably connected and the volumizing appliance comprises an adjustment mechanism to adjust a distance between the scalp facing part 3 and the hair supporting part 4, so as to vary the increase of volume in the hair 8.

In this embodiment, the scalp facing member 10 and the hair supporting member 11 are hinged connected by means of hinge 12. The adjustment mechanism is arranged to adjust an angle α 13 between the scalp facing part 3 and the hair supporting part 4.

In the embodiment shown in FIG. 2, a front part 14 of the insertion member 2, the front part 14 being the part that is inserted between the scalp 7 and the hair 8 first when in use, is bluntly formed, so as to prevent injuring the scalp 7 when the insertion member 2 is inserted. To further prevent injuring the scalp, the front part may also be unheated.

In another embodiment, to ease insertion, the front part 14 of the insertion member 2 may be thinner than the rest of the insertion member 2. The insertion member 2 may e.g. be duckbill shaped, which means that the insertion member 2 has a relatively narrow, blunt front that may conically widen and increase in height towards an end portion of the insertion member 2.

The adjusted front part shapes may of course also be applied to embodiment 1 as shown in FIG. 1.

FIG. 3 shows a front view in the direction of arrow 15 from FIG. 2 of embodiment 101 when in use. Reference numbers in FIG. 3 are identical to the reference numbers in FIG. 1. FIG. 3 A shows embodiment 101 in a substantially closed position and FIG. 3B shows embodiment 101 in an open position. The hair volumizing appliance is preferably inserted into the hair 8 in the closed position, to enable easy insertion. In closed position, the increase of volume is relatively small. Once inserted, the hair volumizing appliance 101 may be opened to heat a larger part of the hair 8 and to further increase the volume of the hair 8.
