       BACKGROUND OF THE INVENTION  
       [0004]     1. Field of the Invention  
         [0005]     The present invention relates to vehicle sunshades and in particular to a vehicle sunshade supportable by two extensible and retractable umbrella type support rods with radial support arms, each attached to a base having a suction cup with a locking pivotable activating arm, the suction cups attachable to the glass surfaces of a windshield and rear window of the vehicle.  
         [0006]     2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 1.98  
         [0007]     Vehicle interiors reach extreme temperatures when exposed to direct sunlight; temperatures too high for living creatures and people to survive if locked within the vehicle for a prolonged period of time. When a person gets into a vehicle exposed to direct sun, the seats, steering wheel and other elements of the vehicle interior are usually too hot to contact.  
         [0008]     Prior art sunshades are often difficult to set up and take down or inadequate in allowing air circulation between the sunshade and the vehicle to further assist in maintaining a cooler vehicle interior.  
         [0009]     Prior art U.S. Pat. No. 4,655,236, issued Apr. 7, 1987 to Dorame, shows a portable carport that includes a foldable cover supported at its four corners by four telescoping assemblies each including an outwardly inclined telescoping mast. Each mast includes first and second anchoring legs, each having a foot wedged between the ground and the front and rear portions of the tread of the vehicle, respectively. A lateral anchoring assembly attached to each mast includes a lateral member having a plate which presses against an upper portion of the side wall of the adjacent tire and a clamp device that extends across the tread to engage the opposite inner wall of that tire and pulls the mast toward the tire, forcing the plate against the outer side wall, thereby maintaining the mast at a fixed angle of inclination relative to the plane of the tire. A removable spacer resting on the roof of the automobile pushes the center of the flexible cover upward to provide an air space between it and the top of the automobile. This allows rainfall to run off the top of the cover.  
         [0010]     Prior art U.S. Pat. No. 4,858,985, issued Aug. 22, 1989 to Wojcik, claims a vehicle cover protector which protects most exposed parts of a motor vehicle from harsh climatic conditions including sun, rain, chemical fallout, pollution, dust, snow, sleet and hail. The cover is attached either within the vehicle or attached externally, mounted within a housing. A retractable cover covers the surface of the car. The cover may also be mounted over supporting members in order to provide additional protection from damage due to hail. The cover may be mounted upon two adjustable poles, which further provides for a sunshade available to persons or objects adjacent to the vehicle.  
         [0011]     Prior art U.S. Pat. No. 4,805,654, issued Feb. 21, 1989 to Wang, illustrates a sun shield for automobiles which has a collapsible framework for supporting a flexible cloth. The framework has at least three legs radially and isometrically extended from the framework. In the free end of each leg there is a sucker adapted to attach to the roof of an automobile. Therefore, the cloth can be easily mounted above an automobile to shade it from the unpleasant and damaging effects of the sun&#39;s rays, and it can also be easily detached from the roof of the automobile and folded into the trunk of the automobile.  
         [0012]     Prior art U.S. Pat. No. 5,388,883, issued Feb. 14, 1995 to Yang, relates a sun shield cover for a vehicle and the like is formed from a round-shaped and lightweight plastic sheet with an apron around the side. An elastic wire is sewn around to support the round shape. After one pushes the round shape into an oval one, two non-elastic plastic belts are used to keep the oval shape. A thin elastic wire is used to raise the central part of the oval-shaped shield to an umbrella shape. Two ear-shaped belts on the side of the shield are connected to the elastic fixing belt to fix the whole shield onto the top of the vehicle.  
         [0013]     Prior art U.S. Pat. No. 5,921,259, issued Jul. 13, 1999 to Ehler, concerns a portable vehicle shade assembly. The shade assembly comprises a canopy, a support structure coupled with the canopy, a support member operably coupled with the support structure for moving the support structure from a first position to a second position for moving the canopy from a closed position to an open position, and an engagement mechanism for detachably engaging the support member with the body of the vehicle, the canopy to extend outwardly from the support member in the open position to substantially shade the compartment of the vehicle exteriorly of the compartment.

The cover is substantially comprised of a sheet of cloth, several foam runners, and several attaching straps. The foam runners, preferably having a rectangular cross section, attach to the underside of the cloth. When placed on a vehicle, the foam runners support the cloth in a spaced apart relationship with the top of the vehicle. The attaching straps securely attach the cover to the vehicle by attaching to the wheel wells and the front and rear bumpers of the vehicle. The attaching straps hold the cloth in a taut condition so that the cloth remains in a spaced apart relationship with the top of the vehicle. Falling objects, such as hail, are repelled by the taut cloth and damage to the vehicle is prevented. The foam runners and straps are adjustable so that the cover fits a variety of vehicles.  
         [0022]     What is needed is a vehicle sunshade which mounts and removes easily by a single person and which supports the sunshade over the entire vehicle interior slightly elevated above the vehicle to allow air circulation between the sunshade and the vehicle.  
       BRIEF SUMMARY OF THE INVENTION  
       [0023]     An object of the present invention is to provide a vehicle sunshade which mounts and removes easily by a single person and which supports the sunshade over the entire vehicle interior slightly elevated above the vehicle to allow air circulation between the sunshade and the vehicle.  
         [0024]     Another object of the present invention is to provide a vehicle sunshade having dual umbrella supports which are mounted to the windshield and rear window by using a mechanically activated suction cup base which comprises a locking mechanism to releasably and securely attach the suction base to the glass and to prevent theft of the umbrella supports.  
         [0025]     In brief, the present invention provides a sunshade for a vehicle supported by dual umbrella structures. The umbrella support structures mount, one on the front windshield and one on the rear window of the vehicle. The umbrella supports use a strong mechanically activated suction cup to mount on each window. The sunshade is easy to mount and each of the upright umbrella supports from each of the two suction cup mounts is positioned strategically, well along the length of the sunshade, so that only the two supports are required to hold the sunshade in an elevated position above the vehicle for adequate shading of the vehicle. The suction cup mounting bases each have a locking mechanism, such as an upright lock bar that inserts within an opening through a suction-controlling lever arm. The locking mechanism locks to secure the lever arm down in the suction position, and is releasable only by using a key.  
         [0026]     An advantage of the present invention is that mounting it on the windshield and rear window provide ease of installation and access.  
         [0027]     A further advantage of the present invention is that mounting it on the windshield and rear window with umbrella type mounts positions the mounts in the optimum location for sharing the support of the sunshade material and maintaining it above the vehicle with air circulating between the sunshade and the vehicle.  
         [0028]     Another advantage of the present invention is that the umbrella type mounts are releasably and securely attached to the glass.  
         [0029]     Yet another advantage of the present invention is that the locking suction bases prevent theft.
