Definitions

  • the present invention relates to a hair styling product. More particularly, the present invention relates to a hair straightener or straightening device that uses hot air to straighten or smooth the hair.
  • a variety of different devices and methods may be used for straightening hair.
  • the user may employ a hairbrush to place tension on his or her hair while applying heated air with a hair dryer.
  • the user gathers a portion of hair and extends it away from the user's head.
  • the extended hair portion is then treated with heated air to enable it to retain its extended shape.
  • this method is a two-handed procedure that requires agility, concentration and, thus, can be strenuous and tiresome for the user.
  • the appliance has various styling attachments, such as a brush or a comb, which attach to the nozzle of the hair dryer, and typically having an elongated body with a head portion in which the hot air flow exits laterally therefrom.
  • a brush or a comb which attach to the nozzle of the hair dryer
  • the appliance can be manipulated in the same fashion as a common brush, namely one's hair being dried and styled as the user merely brushes or combs his or her hair.
  • the air outlet in a styler/dryer is a larger area than that of the typical blower/dryer and, consequently, the air exits through this outlet at a lower velocity.
  • Hair can also be straightened by applying a relaxing agent to break down the natural curls of the hair.
  • a hair dryer is then typically used to dry the hair and, in some cases, provides the requisite heat necessary to activate the relaxing agent.
  • a curling iron or similar device may facilitate straightening of hair by compressing the hair between flat surfaces of heated iron.
  • the hair straightener comprises a handle having a heat generator and a convector to direct heat away from the handle, a housing connected to the handle and having a heatable surface with one or more vents to release the heat from the housing, a guide for directing hair onto the housing, and a heat distributor adjacent the housing to direct heat from the handle through the vents.
  • the heat generated from the heat generator is directed by the convector into the housing.
  • the heat distributor moves the heat through the housing, thereby heating the heatable surface of the housing and directing heat out of the vents to facilitate the straightening of hair secured by the guide.
  • the present invention also provides an attachment for a hair care device.
  • the attachment comprises: a housing having a heatable surface with vents to release the heat from the housing, a guide for directing hair onto the housing, and a cone-shaped heat distributor in the housing to direct heat from the handle through the vents.
  • the cone-shaped heat distributor also directs heat through the housing, thereby heating the heatable surface of the housing and directing heat out of the vents to facilitate the straightening of hair secured by the guide.
  • Fig. 1 is a top view of the hair straightener of the present invention
  • Fig. 2 is a side view of the hair straightener of Fig. 1 ;
  • Fig. 3 is a side view of a portion the hair straightener of Fig. 1 , turned ninety degrees;
  • Fig. 4 is an opposite side view of the portion of the hair straightener of Fig. 3;
  • Fig. 5 is an end view of the portion of the hair straightener of Fig. 3; '
  • Fig. 6 is an exploded view of the components of the hair straightener of Fig. 1 ;
  • FIG. 7 is a schematic diagram showing the path of the airflow through the hair straightener of Fig. 1.
  • Hair straightener 10 has a body that includes a housing 50 and a handle 70 adapted to be connected to the housing via an adapter 20.
  • housing 50 and handle 70 are in axial alignment.
  • handle 70 has a lower handle 72 and an upper handle 74 that are adapted to be removably connected together. They can be secured together by conventional means, such as, for example, one or more screws or mating surfaces, one of which is female and the other of which is male that are adapted to snap fit to each other. Handle 70 also has a switch (not shown) and switch cover 76, preferably in upper handle 74, that is adapted to activate a power source. The switch cover 76 is secured to handle 70, such as, for example, one or more screws 78. At the end 71 of handle 70, opposite body 50 is a cap or end cap 80. End cap 80 is preferably removable.
  • cap 80 Between end 71 and cap 80, there can be positioned a filter 82. It is noted that the portion of handle 70 that encloses filter 82 has a plurality of holes or apertures 81 to permit the filter to breathe.
  • cap 80 is the connection from handle 70 to a power source, such as, for example, an AC power source.
  • Both lower handle 72 and upper handle 74 are made of an appropriate material, such as plastic, metal, rubber or wood.
  • the material is plastic.
  • housing 50 has a heatable surface or heat transmissive plate 56 with one or more vents 58 that permit the release of the heat from the housing.
  • Housing 50 is adapted to receive a covering 60 about its outer exterior.
  • covering 60 is a two-piece structure that surrounds heat transmissive plate 56.
  • Covering 60 has two or more, and preferably a series (which is at least three) of rings 61 , and two or more, and preferably a series of, guides or teeth or series of tines 62.
  • the series of rings 61 are preferably curved, and surround the exterior of housing 50.
  • the teeth or series of tines 62 protrude from housing 50 to evenly distribute hair.
  • the covering 60 is held together at the top by a tip 52 and at the bottom by adapter 20.
  • Adapter 20 operatively connects and secures housing 50 and covering 60 to handle 70 and allows for the transmission of air from the handle to the housing. Further, adapter 20 prevents any rotation or movement of covering 60, thereby allowing for hair to be securely guided for straightening.
  • Heat transmissive plate 56 is preferably made of a material that is capable of absorbing heat from the hot air produced by the fan located in handle 70 and transmitting the absorbed heat to the user's hair.
  • a material is metal, such as aluminum, or a heat conducting polymer, such as a talc-filled nylon, or a metal filled polycarbonate.
  • covering 60 is made of plastic.
  • the rings 61 and teeth 62 may be made of plastic, rubber, or any mixtures thereof. However, the curved rings 61 and teeth 62 may also be integral to covering 60 as shown in the figures.
  • housing 50 is preferably cylindrical. Housing 50 has an air restrictor or air baffle 66 that is connected to a heat distributor or air diverter 64.
  • connection is removable.
  • Baffle 66 is preferably located in the center of housing 50.
  • Heat transmissive plate 56 surrounds the air baffle 66 and air diverter 64.
  • the one or more vents 58 of heat transmissive plate 56 direct the heated air.
  • the heat distributor or diverter 64 in housing 50 directs heat from handle 70 through the one or more vents 58.
  • diverter 64 is cone-shaped to facilitate the direction of heat. In a preferred embodiment, the tip of the cone-shape of diverter 64 is directed to handle 70.
  • heat transmissive plate 56 is preferably laterally curved so that the hair may glide over its upper surface. Also, heat transmissive plate 56 is situated underneath covering 60 such that curved rings 61 surround heat transmissive plate 56.
  • the rings 61 are designed so that neither the user's scalp nor neck, come into contact with heat transmissive plate 56. The rings 61 help to separate and guide the user's hair.
  • the plurality of teeth 62 of covering 60 weave through the user's hair and pull the hair to create tension so that the hair is drawn evenly and tightly across heat transmissive plate 56. Thus, the tension of pulling the user's hair straightens the hair, and the action of drawing the hair across heat transmissive plate 56 causes the hair to be straightened.
  • housing 50 is preferably connected to handle 70 by adapter 20, which is preferably configured to releasably receive and secure both housing 50 and handle 70.
  • Adapter 20 also preferably is configured to enable housing 50 to be releasably connected to various different hair care devices. However, any other method of connection which allows for the transferability of housing 50 to other hair care devices may also be used.
  • housing 50 can be readily attached and detached from handle 70, and readily attached onto another hair care device such as, for example, a hair dryer.
  • Fig. 6 also shows adapter 20 and housing 50 with components thereof that make up and connect the housing to handle 70. These components include cap 52, air baffle 66, air diverter 64, heat transmissive plate 56 with vents 58, and covering 60 with rings 61 and teeth 62.
  • Air baffle 66 preferably has a plurality of openings and functions to restrict the flow of air from handle 70 to housing 50 and to distribute the airflow evenly through and between each vent 58 in housing 50.
  • Air diverter 64 as described above, facilitates the transfer of heated air from housing 50 to heat transmissive plate 56 and vents 58.
  • Fig. 7 illustrates the air flow pattern through housing 50.
  • An additional feature of the present invention is a "cool shot button" that allows for momentary removal of heat from device 10 yet continues the flow of air to cool and set hair after straightening.
  • This is preferably accomplished by the arrangement of the heat generator with the convector.
  • a portion of the heat generator serves as a voltage dropping, series resistor for the convector.
  • the heat generator is switched off and the portion of the heat generator that is in series with the convector remains open. This allow for the convector to continue to operate and generate an airflow while the heat generator ceases to produce heat thereby creating cool shot of air.
