Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to hair and more particularly to methods of preparing synthetic hair, such as for example synthetic hair braids.

2. Description of the Related Art

Synthetic fibers have been used in wigs for many years. More recently, synthetic fibers have been introduced as synthetic braids which can be intermingled with natural hair to create a new and popular fashion trend. However, the braids must first be finished past the length of the natural hair, by being cut to an appropriate length and then singed, so they do not unravel.

It is an object of the present invention to provide a novel tool for the preparation of synthetic hair braids.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to the figures, particularly FIGS. 4 and 8, there is provided a [0036] manual device 10 for preparing synthetic hair, having a pair of scissored first and second arms 12, 14, each of the arms supporting one of a pair of mold portions 16, 18 which, when sufficiently externally heated, are capable of cutting and singeing a braid of synthetic hair, when the arms are scissored together. The arms may be made from materials such as steel, which may be stainless or may be painted or otherwise coated. Preferably, the mold portions are made of a cast materials, such aluminum, zinc, iron, or copper or alloys thereof.
In one example, the device has first and second arms which are made from SS[0037] 304 stainless steel which has been coated with a nickel coating known as NEDOX at a thickness of 0.05+/−0.02 mm. The mold portions are cast A124-F aluminum alloy also coated with nickel coating is NEDOX. In both cases, the nickel coating provides reduced friction and increased heat resistance.
Desirably, the device has a hand grip portion [0038] 20, 22 formed on each arm 12, 14, preferably by molding plastics or other materials thereon, which will be appropriately formed to be of comfort to the user.
Each mold portion includes a pair of members [0039] 16 a, 16 b, 18 a, 18 b positioned on opposite sides of the arm which are removably fastened together by way of fasteners 16 c, 18 c. The mold members have complementary surface portions which cooperate to cut the braid of synthetic hair. At least one of the mold members, preferably both, have a plurality of cavities of different diameters to receive the braid.
The mold portions are significant because they may be heated externally, as for example, by using an oven of the type currently used in hair salons. The device is beneficial because it is less expensive than other plug or flame heated devices. The mold portions are of sufficient size that they are capable of retaining sufficient heat to prepare one or a number of braids without having to be reheated. [0040]
Each mold portion [0041] 16 a, 18 a has a plurality of cavities 22 a, 22 b of different diameters to receive the braid therein, wherein the cavities of one mold member are open to the cavities of the other mold member. The mold portion 16 a has a concave inner surface 24 a, while the mold portion 18 a has a convex inner surface 24 b. In this case, the cavities 22 a are located within the concave inner surface 24 a while the cavities 22 b are located within the convex inner surface 24 b.
The [0042] device 10 may be used for the finishing an end of a braid, made from a synthetic fibre such as that known by the trade name KANEKALON, though other synthetic fibers may also be suitable and which are capable of being cut and singed with normal heating temperatures such as, for example, a range of about 150 to 200 degrees Celsius.
The device is placed near a heating element, for example those which resemble a mini pizza oven, that currently exist in professional hair salons, at a temperature ranging from about 150 to 200 degrees Celsius, for sufficient period of time for the mold portions to reach the ambient temperature of this range. After this time period, the device may be left in the oven while the braids are prepared to a point about two inches past their desirable length and beyond the length of the client's natural hair. The heated device is then applied to the braid so that the braid is aligned with the appropriate one of three cavities provided for in the mold portions. In this case, the correct cavity may be the cavity which has a slightly smaller diameter than the braid. The arms are then scissored together to their operative position which results in the braid being slightly compressed by the cavity and therefore molded into the slightly tapered shape thereof. [0043]
The convex and concave surfaces are complementary, allowing for them to abut one another when the arms are in the operative position as shown in FIGS. 1 and 2. Any hair that is located outside the cavity and between the convex and concave surfaces is squeezed away from the cavity. Though not necessary in all cases, the convex and concave surfaces, in this example, may provide a clean end on the molded braid and thereby avoids the jagged edge that can be formed by knife edges. As a result, the braid is shaped or molded by the cavity. This process may be repeated as desired and the device reheated when necessary. It will, of course, be understood that other embodiments of the present invention may not provide the clean end as is provided in FIGS. 1 and 2. [0044]
Thus, the [0045] device 10 offers a number of benefits. It is relatively simple to operate and economical to produce. It is heated externally by means of an oven or the like and therefore eliminates the need for an internal heating element. The device is able to melt and mold the braid end while also cleanly removing excess synthetic hair by the squeezing action of the complementary convex and concave surfaces.
The cavities may either be slightly tapered or not, depending on the type of shape desired for the braid. [0046]
The [0047] device 10 may also be packaged as a kit including a number of alternative mold portions with different cavity sizes and the like, thereby providing for interchangeable mold portions which will offer still more flexibility to the user. The alternative mold portions are illustrated, for example, in dashed lines in FIG. 3.
