Many people have the desire for curled or styled hair. Most people manually style their hair with devices such as curling irons and flat irons, which takes some knowledge of hair styling in order to produce desirable hair styles. Automatic hair styling devices are available, but some can be difficult to use and can result in hair tangling and imperfectly curled or styled hair.
The present invention overcomes the limitation of the prior art by providing an automatic hair styling device designed to produce consistent curls and styles without extensive knowledge or effort from the user with reduced likelihood of tangling.
This invention is directed to a hair styling device that automatically styles a user's hair with very little effort or knowledge required on the part of the user. In one embodiment, the device comprises a handle, an elongated, substantially cylindrical, heatable rod that provides a curling surface and is supported by the handle, a heater for heating the curling surface, a rotatable member rotatable relative to the curling surface for wrapping hair around and in contact with the curling surface of the rod, an opening in the rotatable member for receiving a user's hair, and a motor for rotating the rotatable member.
In one version, there is a support spaced apart from the curling surface of the rod. The device can also comprise two or more supports.
In one version, there are one or more flexible, heat-resistant first clamps supported by the support and extending from the support toward the curling surface for clamping hair against the curling surface of the rod. The distance between the portion of the clamp closest to the curling surface and the curling surface can be from about 0.1 mm to about 3 mm. The clamp can have a first cross sectional area proximate to the curling surface and a second cross sectional area at the support, where the first cross sectional area is less that the second cross sectional area. The clamp can be proximate to the curling surface and can be triangular in lateral cross section. The clamp can be made of an elastomeric material, such as silicone. The clamp is advantageous in that it helps to smooth and polish the user's hair.
In another version, instead of or in addition to the first clamps, one or more second clamps are supported by the rotatable member.
Preferably, the device does not have a housing around any portion of the curling surface of the rod. The lack of a housing is advantageous because the curling surface is accessible and visible to the user 360 degrees around the rod.
The device can also comprise a hook flanking the opening in the rotatable member for engaging the user's hair. The hook can be made from an elastomeric material such as silicone. Optionally, the hook can have finger-like projections formed from the elastomeric material.
There can be a magnet on the rotatable member, a magnet sensor sensing the magnet, and a controller for positioning the opening in the rotatable member in response to the magnet sensor for receiving a user's hair when the rotation of the rotatable member ceases rotation.
A timer can be used to track the amount of time the hair is placed against the curling surface, and sounds an alarm when the hair should be released from the device. The device can further comprise an optical sensor for detecting when hair has been removed from the curling surface. When the hair is removed from the rod, the timer resets to a starting position.
The device can also comprise a flexible, heat-resistant restrainer arm supported by the restrainer arm support which can be one of the clamp support arms. The restrainer arm extends from the restrainer arm support toward the rod. The restrainer arm is advantageous in that it prevents the hair from twisting as it wraps around the rod. The restrainer arm can have a first cross sectional area proximate to the curling surface and a second cross sectional area at the restrainer arm support, the first cross sectional area being less that the second cross sectional area. The restrainer arm can be constrained proximate to the rod and can be triangular in lateral cross section. Optionally, the restrainer arm can move away from the rod in order to release hair from the device. The restrainer arm can be made of elastomeric material, such as, for example, silicone.
The invention also provides methods for using the hair styling devices described above. The device can be used by placing a selected portion of hair through the opening in the rotatable member, and activating the rotatable member so that the rotatable member winds the selected portion of hair around the curling surface of the rod. The hair is smoothed and polished by the clamp during styling. Once curling of the hair is complete, the user pulls the device away from the hair, thereby releasing the hair from the device.

This invention is directed to a hair styling device 100 for automatically styling a user's hair, such as by curling. As shown in
The rod 104 provides a curling surface 105 on which the user's hair is wrapped around and styled. The rod 104 and curling surface 105 can be made of any type of material that is able to be heated and is heat conductive, such as, for example, metal or ceramic. The curling surface 105 can be different material then the remainder of the rod 104. The device 100 does not have an enclosed housing around any portion of the curling surface 105. Thus, the curling surface 105 can be visible, and accessible, 360 degrees around the rod 104. This is advantageous because the device requires less material than if it had an enclosed housing, so that manufacturing costs of the device is reduced. The device 100 also weighs less without a housing, so that the user's arm is less likely to tire from holding the device 100. Another advantage is that the user can view the hair as it is wrapped around the rod 104. Yet another advantage is that since there is no housing, the outside of the device 100 is not heated, which provides a cost savings in manufacturing since heaters are not needed. Furthermore, a user can grasp the outside of the heated device 100 without injury. Additionally, the heated device 100 can be placed directly on a surface such as a counter without fear of the device burning the counter.
The device 100 comprises a handle 102. There is a heater 114 in the handle 102 for heating the rod 104 and curling surface 105, as shown in
The device 100 also comprises a rotatable member 108 located near the proximal end 104a of the rod 104. The rotatable member 108 also has a hub 162 so that the rod 104 can be positioned on it, as shown in
In use, the rotatable member 108 can be rotated 360 degrees by the motor 116 in either a clockwise or counterclockwise direction. The handle 102 can comprise a rotation direction selection switch 126, shown in
The handle 102 contains opening 110 which allows for placement of a section of hair 164 into the device 100. The section of hair 164 typically contains enough strands of hair that the hair can be placed in the opening 110, but not too many strands of hair so that the section of hair 164 is too large to fit inside the opening 110.
The rotatable member opening 170 can form a hook 118, flanking the opening 110 for engaging the user's hair. The hook 118 can also have material for gripping and retaining the user's hair in the rotatable member opening 170. For example, an elastomeric material 109 can be positioned in the nook of the hook 118 as shown in
The purpose the rotatable member opening 170, and in particular the hook 118, is to capture the hair and aid in guiding the hair as it is wound around the rod 104.
As shown in
In one embodiment, the device 100 can have at least one support 106 that is spaced apart from the rod 104. The device can also comprise two or more supports 106. The supports 106 extend parallel to the rod 104 and has a proximal end 107a supported by the lower support element 136 and a distal end 107b supported by an upper support element 138.
In one embodiment, the device 100 comprises a flexible, heat-resistant first clamp 112. In one embodiment, the first clamp 112 extends from the support 106 near the lower support element 136, as shown in
An advantage of the first clamp 112 is that it positions the hair to abut the heated curling surface 105 for the entire styling period. This results in much tighter curls, which are more desirable by the user. The clamping of the hair also facilitates rapid transfer of heat in minimal time, resulting in less damage to the hair. In addition, the clamp helps smooth and polish the user's hair as it passes over the user's hair.
The distance between the clamp and the curling surface 105 can be from about 0.1 mm to about 3 mm. The distance between the first clamp 112 and the curling surface 105 depends on the thickness of the user's hair wrapped around the rod 104. It is contemplated that the first clamp 112 can be a passive clamp, meaning that the clamp has to be engaged by the hair to hold the hair. The end of the first clamp 112 attached to the support 106 is fixed, while the end of the first clamp 112 that is closest to the curling surface 105 moves passively away from the rod as the hair is wrapped around the rod 104. The less hair that is wrapped around the rod, the smaller the distance between the first clamp 112 and the curling surface 105. Conversely, the more hair wrapped around the rod 104, the larger the distance between the first clamp 112 and the curling surface 105.
It is also contemplated that the first clamp 112 can be an active clamp, meaning that it is automatically engaged by a switch or otherwise activated to hold the hair against the curling surface 105.
The first clamp 112 can have a first cross sectional area proximate to the rod 104 and a second cross sectional area at the support 106, the first cross sectional area being less that the second cross sectional area. The first clamp 112 can be triangular in lateral cross section.
The first clamps 112 can be made out of any material that is heat resistant, such as an elastomeric material. The clamp elastomeric material 113 can be, for example, silicone, thermoplastic polyurethane elastomeric rubber, thermoplastic rubber, and polypropylene.
In another embodiment, the device can contain one or more second clamps 154 positioned on the rotatable member 108, as shown in
The device can also contain a flexible, heat-resistant restrainer arm 132, as shown in
The restrainer arm 132 has a first cross sectional area proximate to the curling surface 105, and a second cross sectional attached to the support 106. In one embodiment, the first cross sectional area is less that the second cross sectional area. It is contemplated that the restrainer arm 132 is triangular in lateral cross section. In another embodiment, the restrainer arm 132 is constrained proximate to the curling surface 105 by a notch 134 in the rod 104, as can be seen in
The restrainer arm can be made out of any heat resistant, flexible material, such as, for example, an elastomeric material such as, for example, silicone, thermoplastic polyurethane elastomeric rubber, thermoplastic rubber, or polypropylene.
Optionally, the device 100 can have a timer 130, which tracks the amount of time the hair is placed against the curling surface 105, and sounds an alarm when the hair should be released from the device 100. The device 100 can have any number of timer lengths. The user has the ability to select the timer length depending on the type of hair being styled, the amount of hair in the section, and the style of hair the user is seeking to achieve.
The timer alarm can be in the form of a sound, such as a loud beep or a series of beeps, or the notification can be in the form of a visual indicator, such as a flashing light. Alternatively, the notification can be in the form of a vibration of the device 100 which allows a user who cannot see or hear to know when the timer 130 has gone off. Combinations of two or more notifications can also occur. This is advantageous because a sight or hearing impaired user may require different types of notification.
Additionally, the device 100 can also comprise an optical sensor. The optical sensor can determine when the user's hair has been removed from the device 100, thus allowing the timer 130 to operate effectively and allowing the rotatable member 108 to return to its starting position with the rotatable member opening 170 aligned with housing opening 110 and the lower support element opening 137.
The operation and use of the device 100 will now be described. The device 100 can be used by first turning the device on using the on/off switch 124 and selecting the desired temperature using the temperature controller slide switch feature of 124. Prior to operation of the device, the rotatable member opening 170 is aligned with housing opening 110 and the lower support element opening 137.
As shown in
Once the entire section of hair 164 has been wound around the rod 104, the rotatable member stops rotating, and the timer 130 begins its countdown. Once the end of the countdown is reached, the device 100 will signal to the user that the time has expired and the section of hair 164 is done curling and ready to be released from the device 100.
Once the hair has been heated to the desired temperature for the requisite amount of time, the user can pull the device 100 away from their head, thereby sliding the section of hair 164 from between the clamp and the curling surface and removing the section of hair 164 from the distal end of the device 100 via the vertical movement of the restrainer arm 132.
Although the present invention has been described in considerable detail with reference to certain preferred embodiments, other embodiments are possible. The steps disclosed for the present methods, for example, are not intended to be limiting nor are they intended to indicate that each step is necessarily essential to the method, but instead are exemplary steps only. Therefore, the scope of the appended claims should not be limited to the description of preferred embodiments contained in this disclosure. All references cited herein are incorporated by reference.
