Abstract

An electrically powered, heated flat iron 1 has a first handle 2 and a second handle 3 joined by a hinge 4. An upper plate 6 is attached to the first handle 2, and a lower plate 7 is attached to the second handle 3. The upper plate has a groove 8 that extends generally longitudinally. The lower plate 7 has a set of raised ridges 9, the ridges 9 being aligned in a longitudinally extending row along the lower plate 7 so that the row is aligned with the groove 8.

Description

HAIR STYLING IRON WITH RAISED FINS}

The present invention relates to a handheld hair styling device, and more particularly to a hair styling device with a heating plate.

Various hair styling irons with flat heating plates are known. Some flat irons have a non-planar surface that includes one or more raised contours, grooves, pins, and channels. Each has a specific purpose, such as shaping the hair in a special way or tangling the hair, but nothing provides the best performance for straightening, tangling and maximizing heat transfer simultaneously. For example, a configuration with simply protrusions such as fins or hairs can effectively comb the hair and, in some cases, entangle the hair, but such fins are insufficient heat conductors and thus do not contribute to heat transfer. The result is that heat transfer is almost entirely limited to the iron surface of the plate in direct contact with the hair. In addition, fins tend to stick to tangled hair, especially when a relatively large number is employed, and it becomes difficult to pull them down without causing inconvenience, in particular.

Object of the present invention

It is an object of the present invention to provide a heating styling iron that straightens, entangles, and performs optimal heat transfer in order to overcome the above-mentioned problems.

These and other objects are achieved by the present invention.

Brief Summary of the Invention

According to the present invention, a heating styling iron having two opposing heating surfaces connected in a rotatable manner can be straightened, entangled, by using a row of fin-like protrusions on one flat heating surface. And achieve optimum heat transfer. The pin-like protrusions are arranged in a row in the longitudinal direction and are arranged such that the longer dimensions of the pin-like protrusions are arranged transversely with respect to the longitudinal axis. The projection thus guides the hair along its longer dimension as the iron is pulled down along the hair. Opposite flat heating surfaces have channels or grooves extending longitudinally to accommodate the series of protrusions when the heating surfaces are closed towards each other. The size and shape of the grooves are optimized to accommodate the protrusions with the heating surfaces squeezed around the hair of the hair.

1 is a perspective view of a heated iron in accordance with the present invention, including additional partial views showing various components.

The flat heating iron 1 according to the invention comprises a first member 2 and a second member 3 connected by a hinge 4. The wire 5 extends to provide electrical energy from an external power source. The upper plate 6 is attached to the first member 2, and the lower plate 7 is attached to the second member 3. The top plate comprises a groove 8 extending generally in the longitudinal direction. The bottom plate 7 comprises a series of protruding protrusions 9, each protrusion 9 having a length L, a thickness T, and a height H, where L is greater than T. The protrusions 9 are arranged in rows extending longitudinally along the lower plate 7 so that the rows are aligned with the grooves 8. Each projection 9 is arranged in the transverse direction with respect to the row whose length L extends in the longitudinal direction. The row of protrusions may be formed on an auxiliary plate fitted to the lower plate 7 or the protrusions may be integrally formed on the lower plate.

Conventional electrical heating is provided on either or both of the plates 6, 7. Conventional control buttons and dials are used as control controls including thermal controls. The various surfaces may be treated, coated or made of ceramic, tourmaline, nonmetals and other materials. Ion generators and far infrared generators may be included. The iron 1 may be vented for moisture and drying, may be provided with a steam generator and a water reservoir, and may be equipped with a fan that blows air.

While the preferred embodiments of the invention have been shown and described herein, various modifications can be made without departing from the scope of the invention.
