BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to the field of environmental covers for automobiles in general. In particular, the present invention relates specifically to an environmental cover for an automotive windshield.
2. Description of the Known Art
As will be appreciated by those skilled in the art, a cover may be used to protect the windshield of an automobile. Details of a typical protector for a windshield are contained in U.S. Pat. No. 3,964,780, issued to Naidu on Jun. 22, 1976 and U.S. Pat. No. 4,811,982 issued to Carlyle on Mar. 14, 1989. Each of these patents is hereby expressly incorporated by reference in their entirety.
U.S. Pat. No. 3,964,780, issued to Naidu on Jun. 22, 1976 discloses Snow Protectors for Windshields. This is described as a disposable wind-shield snow protector adapted to be removably adhered to the wind-shield of an automobile, bus, truck and the like including a flexible protection sheet and a backing sheet in overlying relationship to each other. The protection sheet includes a cord reinforcing secured to the rearward side thereof and is affixed to a handle located beyond the periphery of the protection sheet. The backing sheet is adapted to be peeled away from the protection sheet to expose an adhesive coating that adapts the device to be removably secured to any desired wind-shield. Removal by hand is easily facilitated by use of the handle provided. The device is then discarded.
U.S. Pat. No. 4,811,982 issued to Carlyle on Mar. 14, 1989 discloses an Automotive Window Shield and Covering. This is described as an automobile window shield and cover formed of a thin, disposable sheet of strong water resistant paper, plastic, or similar inexpensive material. The sheets are factory cut to approximate the size and shape for various sized automobile (and other vehicle) windows, such as windshields, rear and side windows, and have an adhesive backing which is factory-applied to at least peripheral edge regions of the back to enable the sheets to be adhered to an appropriate automobile window in such a manner as to cover most of it, thereby protecting it against the buildup of snow and ice in winter weather conditions. Peeling the sheet from the window before the automobile is to be driven, thus enables the driver to remove any snow and ice from the window. The sheets may be perforated from one edge to an opposite edge in one or more places, to enable the sheets to be selectively removed in sections or strips, and may be provided in pads of a number of sheets for user convenience.
Thus, it may be seen that these prior art patents are very limited in their teaching and utilization, and an improved automotive windshield cover is needed to overcome these limitations.
SUMMARY OF THE INVENTION
The present invention is directed to an improved automotive windshield cover. In accordance with one exemplary embodiment of the present invention, a windshield cover is provided for in at least four different embodiments. In the first embodiment the cover extends across the windshield, covers a small portion of the roof, extends to cover the wipers, and is secured inside each door. In the second embodiment the cover extends across the windshield, covers the roof all the way back to the rear edge of the front doors, extends to cover the wipers, and is secured inside each door. In the third embodiment the cover extends across the windshield, covers the rear doors and extends to cover the rear windshield, extends to cover the wipers, and is secured inside each door. In the fourth embodiment the cover extends across the rear windshield, covers a small portion of the roof, and is secured inside each rear door.
Advantages of the present invention include: no standing in the cold weather for the scraping of ice; no problems with folding up a used cover which has ice covering it because the cover is disposable, no wasting fuel in heating up the vehicle, the doors of the automobile won't be frozen shut; and not waiting to remove ice or peeling off of the adhesive nature of the cover.
Other embodiments provided by the present invention also provide an improved automotive windshield cover for an automobile. These covers also use a pliable sheet with a central body that will cover the windshield. Two side tabs are adapted to be secured between the side doors and the door frames to hold the cover in place. Additional improvements include the use of a pliable sheet having a non-stick surface, a top tab to effectively overlay the roof of the automobile, and a bottom tab to cover the cowl vent and at least a part of the hood. A method for using the windshield cover is also taught as well as a unique distribution system including a plastic roll distribution for disposable covers.
These and other objects and advantages of the present invention, along with features of novelty appurtenant thereto, will appear or become apparent by reviewing the following detailed description of the invention.

DETAILED DESCRIPTION OF THE INVENTION
As shown in FIGS. 1 through 5 and FIG. 9 of the drawings, exemplary embodiments of the present invention are shown as a windshield cover 200 for covering the windshield 102 of an automobile 100. The application of the present invention is for use on an automobile 100. As is well known in the art of automobiles 100, spring biased wipers 104 may be used for removing rain and sleet form the windshield 102. Automobiles 100 are also well known to have a hood 106 with the separation of the hood 106 to the windshield 102 being known as a cowl vent 108. The cowl vent 108 has a left vent side 110 and a right vent side 112. The automobile 100 is also typically constructed with a solid or convertible roof 114. The automobile will also typically have a first side door 116 sealably closing onto a first door frame 118 and a second side door 120 sealably closing onto a second door frame 122.
The present invention is directed to an automotive windshield cover 200 constructed from a pliable sheet 202. The pliable sheet 202 defines a central body 204 which has an environment exposure side 206 and a windshield side 208 with either of both of these providing a non-stick surface 214. Flexibly connected to the central body 204 as a part of the pliable sheet is a first side tab 210 and a second side tab 212 with alternative constructions including either of both of a top tab 216 and a bottom tab 218. The bottom tab is unique in having a contoured shape 220 with a relaxed angle approach 222 so that the bottom tab may fit into the cowl vent 108.
As shown in the drawings, the window cover 200 has a length 262 and a width 264 and is manufactured from a sheet of material having a small mil thickness. Typical thickness is in the range of from 0.74 to 1.5 Mil and depending on the material utilized. The referred embodiment uses a 1.1 Mil thickness, but these numbers should not be interpreted to limit the materials or thicknesses which may be utilized.
FIG. 4 shows one embodiment in which the windshield cover 200 is constructed to define a top edge 224 connected by a top to first side angle 226 to a first side edge 228. The first side edge 228 connects through a first side to contour angle 230 to a first side primary contour edge 232. The first side primary contour edge 232 connects through a first side initial contour angle 234 to a first side secondary contour edge 236. The first side secondary contour edge 236 then connects through a first side secondary contour angle 238 to a first side tertiary contour edge 240. This then provides the connection for the first contour to bottom angle 242 for connecting to the bottom edge 244. Similar to the first side the second side shows how the bottom edge 244 connects through a second contour to bottom angle 246 to a second side tertiary contour edge 248 which connects through a second side secondary angle 250 to a second side secondary contour edge 252. The second side secondary contour edge 252 then connects through a second side primary angle 254 to the second side primary counter edge 256 which is connected through the second side initial contour angle 258 to the second side edge 260. The second side edge 260 is connected through the top to second side angle 221 to the top edge 224.
