Benefits of technology

[0006] Accordingly, present invention has several objects and advantages.
[0007] 1. Enclosed wrapping of the ceramic core with a metal casing differentiates this product with conventional iron tools currently on the market.
[0008] 2. The heat trapping effect design allows ceramic core to retain heat longer than the opened metal casing, allowing the user to use the present invention longer without having to re-heat so.
[0009] 3. Heat is evenly and predictably distributed on the heating surface when ceramic compound touches all heating surface. Since the ceramic compound retain heat longer than metal, having constant contact with metal surface prevents hot spots on the heating surface. Hot spots occur when certain areas cool faster than other.

Problems solved by technology

If curling irons are excessively hot, they will often damage hair and may injure users who accidentally place the heated region too near their skin.
Unfortunately, the electrical heating element must be carefully regulated to avoid burning hair.
A variety of under heated or over heated electrical heating methods has eroded consumer confidence in certain electrically heated curling irons.
Inventor McGee mentions the concern of the metal iron being too heavy and causing fatigue for stylists.

first embodiment

[0031] The first embodiment as seen in figure one shows the hair iron 110 having an upper handle sleeve 145 and a lower handle sleeve 150 enveloping a pair of handles 140 and pivotally cooperating at a pivot junction 135 also called the clip assembly point. The clip extension protrudes from the clip assembly 135 and terminates in a pair of barrels. The upper barrel 120 is parallel to a lower barrel 125 and forms a pair of tong blades 115.

[0032] A pair of tong blades include a first tong blade and a second tong blade the upper barrel may have a semicircular cross section comprising a ceramic core enveloped in a metal jacket mounted on the first tong blade. The lower barrel may have a semicircular cross section comprising a ceramic core enveloped in a metal jacket mounted on the second tong blade. The upper and lower barrels meet to form an interface for holding hair to be straightened, while an upper handle and a lower handle form a pair of handles. The clip assembly pivotally joins ...

second embodiment

[0035] A second embodiment shown in FIG. 4 includes a single barrel 440 cooperating with a lower blade. The lower blade is curved and formed of rigid metal planar material and does not contain ceramic heat emitting material. The barrel holds a strand of hair and can curl hair wrapped around the outside circumference of the barrel. The cross sectional view shown in FIG. 5 provides a curved hair travel path. The ceramic material shown in FIG. 5C has a large cross section and is thus capable of retaining a substantial amount of heat.

[0036] The second embodiment shows what is typically referred to as a “curling iron.” Not only does the second embodiment allow a user with straight hair waves and curls, it also provides volume for those with finer hair. The size of the cylinder that makes up this tool is crucial; the larger the circumference of the cylinder, the larger the curls become. The curling iron with the larger cylindrical circumference produces bigger waves, while the curling iro...

third embodiment

[0037] the present invention includes the device shown in figure six and seven. The lack of a ceramic core in the upper and lower blade allow a user to cool hair, or present limited heat for hair. As seen in the cross sectional view of FIG. 7. The upper blade fits into the lower blade forming a curved path for hair. The curved path is useful in a variety of cosmetology implementations.

[0038] The third embodiment in FIG. 7 represents a tool that can serve as both a curling and straightening device. Since using the curling iron may improperly create angular creases at its ends, this tool is useful to smooth creases while leaving a curly accent to the ends. The third embodiment of the invention can also be used after blow-drying to smooth hair, similar to the effects of the flat iron, of the first embodiment. The crescent design of this tool however, will leave a slight wave rather than dull and straight ends. This tool can also be used to flip a user's hair outwards. This would be a p...

Abstract

A hair iron for straightening hair has a pair of tong blades. An upper and lower barrel of varying cross section with a solid ceramic core is enveloped in a metal jacket. Handles join tong blades and handle sleeves are mounted on the handles for free one-handed rotation.

Description

FIELD OF INVENTION [0001] The present invention relates to hair curling irons used to curl or straighten women's hair. DISCUSSION OF RELATED ARTS [0002] Since the early 1920's, hair curling irons have been used to create various styles of hair curls or to straighten women's hair. The curling irons have been typically heated, either by electricity or by the use of ovens. [0003] If curling irons are excessively hot, they will often damage hair and may injure users who accidentally place the heated region too near their skin. It has been discovered that human hair is well absorbent to infrared radiation in the range of 5 to 10. mu.m. Inventor Takimae in U.S. Pat. No. 4,740,669 points to ceramic materials like zirconia magnetite and alumina as being well adapted to radiating infrared radiation in this range. As a result, Inventor Takimae created a curling iron using ceramics on the outer surface of the curling iron rod. Unfortunately, the electrical heating element must be carefully reg...
