VI. DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIGS. 1 through 3 thereof, a new pneumatic windshield clearing system embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 3, the pneumatic windshield clearing system 10 generally comprises a blower assembly 20, a suction assembly 30, and air source assembly 40.
The blower assembly 20 is preferably positioned on the hood of an automobile. The blower assembly 20 has at least one outlet 21 for directing high pressure airflow onto the windshield of the automobile for forcing rain, snow, and other debris off of the windshield. The blower assembly 20 is operationally coupled to the air source assembly 40.
The blower assembly 20 may include a shield portion 22 extending through the hood of the automobile. The shield portion 22 protects the outlet 21 and facilitates the direction of the air. The shield portion 22 may also facilitate directing airflow passing over the hood of the automobile.
Preferably, the blower assembly 20 includes a plurality of outlets 21 positioned along a bottom edge of the windshield to increase the area of coverage.
The suction assembly 30 is positioned on a perimeter of the windshield. The suction assembly 30 takes in air, rain, snow and other debris from the windshield through suction. The suction assembly 30 may be operationally coupled to the air source assembly 40.
Preferably, the suction assembly 30 includes a plurality of suction inlets 31 deployed along the perimeter edge of the windshield for maximizing the area of coverage.
The air source assembly 40 provides high pressure air to the blower assembly 20. The air source assembly 40 may be operationally coupled to the automobile.
In use, the system is activated whenever rain, snow, or other debris is blown of falls onto the windshield. The blower assembly forces the debris off of the windshield, while the suction assembly similarly pulls debris of the windshield. The combined action facilitates clearing the windshield without the need for wipers.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
