ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to synthetic fiber cutting tools and more particularly pertains to a new tool for sealing synthetic hair when it is braided.
2. Description of the Prior Art
The use of synthetic fiber cutting tools is known in the prior art. More specifically, synthetic fiber cutting tools heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.
Known prior art includes U.S. Pat. No. 5,472,654; U.S. Pat. No. 3,934,115; U.S. Pat. No. 5,309,640; U.S. Pat. No. 3,474,224; U.S. Pat. Des. No. 132,140; and U.S. Pat. No. 1,532,610.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new tool for cutting synthetic hair. The inventive device includes an electric heating element and cutting blade which cuts and seals the hair in one step.
In these respects, the tool for cutting synthetic hair according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of sealing synthetic hair when it is braided.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of synthetic fiber cutting tools now present in the prior art, the present invention provides a new tool for cutting synthetic hair construction wherein the same can be utilized for sealing synthetic hair when it is braided.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new tool for cutting synthetic hair apparatus and method which has many of the advantages of the synthetic fiber cutting tools mentioned heretofore and many novel features that result in a new tool for cutting synthetic hair which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art synthetic fiber cutting tools, either alone or in any combination thereof.
To attain this, the present invention generally comprises a bottom member having a first side, a second side, a third side, a forth side, a top surface and a bottom surface. The first and third sides are parallel to each other. The bottom member has a periphery defined by the area between the top and bottom surfaces.
A heating element having a length, a width and a height such that the length is substantially greater than the width and the height. The heating element is mounted in the bottom member such that its length is adjacent and parallel to the first side of the bottom member.
An electrical power switch is located between the top and bottom portions of the bottom member. An electrical cord having wires extending through the periphery of the bottom member such the heating element and the switch are connected together.
A hinge mechanism attached to the bottom member on the top portion thereof wherein the hinge mechanism has a direction of operation parallel to the first side of the bottom member.
A top member having a first side, a second side, a third side, a forth side, a top surface and a bottom surface. The first and third sides are parallel to each other. The bottom member has a periphery defined by the area between the top and bottom surfaces.
The top member forms generally the same shape as the bottom member. The top member has a notch removed from the bottom portion adjacent to the first end. The notch has a length, width and depth such that it can house the hinge mechanism.
The top member is attached to the bottom member by the hinge mechanism such that the bottom surface of the top member covers and is generally aligned with the top portion of bottom member.
A metallic blade is removably attached to the bottom surface of the top member.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.
As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
Further, the purpose of the foregoing abstract is to enable the U.S. Patent and Trademark Office and the public generally, and especially the scientists, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application. The abstract is neither intended to define the invention of the application, which is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.
It is therefore an object of the present invention to provide a new tool for cutting synthetic hair apparatus and method which has many of the advantages of the synthetic fiber cutting tools mentioned heretofore and many novel features that result in a new tool for cutting synthetic hair which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art synthetic fiber cutting tools, either alone or in any combination thereof.
It is another object of the present invention to provide a new tool for cutting synthetic hair which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new tool for cutting synthetic hair which is of a durable and reliable construction.
An even further object of the present invention is to provide a new tool for cutting synthetic hair which is susceptible of a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such tool for cutting synthetic hair economically available to the buying public.
Still yet another object of the present invention is to provide a new tool for cutting synthetic hair which provides in the apparatuses and methods of the prior art some of the advantages thereof, while simultaneously overcoming some of the disadvantages normally associated therewith.
Still another object of the present invention is to provide a new tool for cutting synthetic hair for sealing synthetic hair when it is braided.
Yet another object of the present invention is to provide a new tool for cutting synthetic hair which includes a one step method of cutting and sealing the synthetic hair.
Still yet another object of the present invention is to provide a new tool for cutting synthetic hair that avoid the use of open flames and candles which are a prevalent method of sealing synthetic hairs. The use of open flame is dangerous, time consuming and often inaccurate.
Even still another object of the present invention is to provide a new tool for cutting synthetic hair t
