ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to windshield wipers and more particularly pertains to a new full coverage windshield wiper for completely cleaning a windshield of a vehicle.
2. Description of the Prior Art
The use of windshield wipers is known in the prior art. More specifically, windshield wipers 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 windshield wipers include U.S. Pat. Nos. 4,274,175; 5,093,953; U.S. Pat. No. Des. 307,408; U.S. Pat. Nos. 5,291,109; 5,327,613; and 5,009,459.
In these respects, the full coverage windshield wiper 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 completely cleaning a windshield of a vehicle.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of windshield wipers now present in the prior art, the present invention provides a new full coverage windshield wiper construction wherein the same can be utilized for completely cleaning a windshield of a vehicle.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new full coverage windshield wiper apparatus and method which has many of the advantages of the windshield wipers mentioned heretofore and many novel features that result in a new full coverage windshield wiper which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art windshield wipers, either alone or in any combination thereof.
To attain this, the present invention generally comprises a vehicle having a front or rear windshield frame. As shown in
FIG. 1
, the frame includes an inner peripheral edge with a pair of generally vertical side edges. Each vertical side edge has both a forwardly extending peripheral lip and a rearwardly extending peripheral lip. These lips reside in coplanar relationship with respect to each other and further perpendicular with the inner peripheral edge, as shown in
FIGS. 3 & 4
. The forwardly extending lips each have a front inwardly extending flange integrally coupled thereto. The rearwardly extending peripheral lips each have a rear inwardly extending flange integrally coupled thereto. As such, the rear inwardly extending flange is adapted for defining a slot with the corresponding front inwardly extending flange.
FIGS. 2-3
show a pair of elongated elastomeric bushings with a generally U-shaped cross-section along an entire length thereof. The elastomeric bushings are each situated within one of the slots of the vehicle windshield frame. In operation, the bushing work to maintain a transparent windshield within the frame of the vehicle. Next provided is a full horizontally oriented, linear windshield wiper formed from a flexible elastomeric material. The windshield wiper has a length equal to a width of the windshield. A pair of ends of the wiper are each equipped with a rigid slider block mounted thereon. As shown in
FIG. 4
, each slider block is slidably situated within one of the slots between the front inwardly extending flange and the windshield. An actuation assembly is provided including a pair of pulley units. The pulley units each include a top pulley rotatably mounted within one of the slots adjacent a top end thereof. For ensuring coincident rotation of the top pulleys, an elongated post is fixed in coaxial relationship therebetween. Each pulley unit further has a lower pulley rotatably mounted adjacent to a lower end of the corresponding slot. The lower pulleys are maintained in communication with the associated top pulley via a band. For reasons that will soon become apparent, each band is coupled to an associated one of the slider blocks of the windshield wiper. Note FIG.

. Coupled to one of the bottom pulleys is a motor for raising and lowering the windshield wiper.
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 full coverage windshield wiper apparatus and method which has many of the advantages of the windshield wipers mentioned heretofore and many novel features that result in a new full coverage windshield wiper which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art windshield wipers, either alone or in any combination thereof.
It is another object of the present invention to provide a new full coverage windshield wiper which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new full coverage windshield wiper which is of a durable and reliable construction.
An even further object of the present invention is to provide a new full coverage windshield wiper 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 full coverage windshield wiper economically available to the buying public.
Still yet another object of the present invention is to provide a new full coverage windshield wiper 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 full coverage windshield wiper for completely cleaning a windshield of a vehicle.
Even still another object of the present invention is to provide a new full coverage windshield wiper having a pair of ends slidably situated with respect to a windshield of a vehicle. The wiper is adapted for sliding between a top end and a bottom end of the windshield and further constantly remaining in a full coverage orientation. Further provided is motor and pulley sys
