ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to ice scrapers and more particularly pertains to a new circular windshield ice scraper for scraping ice and frost off of the windshield and windows of a vehicle.
2. Description of the Prior Art
The use of ice scrapers is known in the prior art. More specifically, ice scrapers 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. 4,422,206; U.S. Pat. No. 3,214,834; U.S. Pat. No. 5,263,222; U.S. Pat. No. 4,275,476; U.S. Pat. No. 4,719,660; and U.S. Pat. No. Des. 156,638.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new circular windshield ice scraper. The inventive device includes a scraping blade has a top face, a generally frusta-conical perimeter side, and a downwardly facing concave bottom face. The perimeter side and the bottom face of the scraping blade form a generally circular lower scraping edge designed for scraping ice off of a surface. The ice scraper also includes a body coupled to the scraping blade. The body has a generally frusta-conical lower portion and an upper portion. The upper portion is designed for grasping by a user's hand.
In these respects, the circular windshield ice scraper 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 scraping ice and frost off of the windshield and windows of a vehicle.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of ice scrapers now present in the prior art, the present invention provides a new circular windshield ice scraper construction wherein the same can be utilized for scraping ice and frost off of the windshield and windows of a vehicle.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new circular windshield ice scraper apparatus and method which has many of the advantages of the ice scrapers mentioned heretofore and many novel features that result in a new circular windshield ice scraper which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art ice scrapers, either alone or in any combination thereof.
To attain this, the present invention generally comprises a scraping blade has a top face, a generally frusta-conical perimeter side, and a downwardly facing concave bottom face. The perimeter side and the bottom face of the scraping blade form a generally circular lower scraping edge designed for scraping ice off of a surface. The ice scraper also includes a body coupled to the scraping blade. The body has a generally frusta-conical lower portion and an upper portion. The upper portion is designed for grasping by a user's hand.
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 circular windshield ice scraper apparatus and method which has many of the advantages of the ice scrapers mentioned heretofore and many novel features that result in a new circular windshield ice scraper which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art ice scrapers, either alone or in any combination thereof.
It is another object of the present invention to provide a new circular windshield ice scraper which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new circular windshield ice scraper which is of a durable and reliable construction.
An even further object of the present invention is to provide a new circular windshield ice scraper 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 circular windshield ice scraper economically available to the buying public.
Still yet another object of the present invention is to provide a new circular windshield ice scraper 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 circular windshield ice scraper for scraping ice and frost off of the windshield and windows of a vehicle.
Yet another object of the present invention is to provide a new circular windshield ice scraper which includes a scraping blade has a top face, a generally frusta-conical perimeter side, and a downwardly facing concave bottom face. The perimeter side and the bottom face of the scraping blade form a generally circular lower scraping edge designed for scraping ice off of a surface. The ice scraper also includes a body coupled to the scraping blade. The body has a generally frusta-conical lower portion and an upper portion. The upper portion is designed for grasping by a user's hand.
Still yet another object of the present invention is to provide a new circular windshield ice scraper that allows a user to use a circular motion to remove ice from a windshield or window.
Even still another object of the present invention is to provide a new circular windshield ice scraper that lets a user apply more force to remove ice than is possible with conventional ice scrapers.
These together with other objects of the invention, along with the various features of novelty which characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and the specific objects attained by its uses, reference should be made to the accompanying drawings and descriptive ma
