Abstract:
A Collapsible Car Sun Shade assembly installed on vehicle consists of non-perforated Fabric having multiple eye-lets on its corners for covering the vehicle&#39;s roof surface. The Fabric has air outlets, covering with Lids made of ultra-light material. Lids are attached with the Fabric by means of strings, which are long enough to move themselves upward by the air pressure build under the Fabric. The Fabric is deployed on weather proof Telescopic Pipes having four levels and equipped with spring pin-locks. The top end of the upper level of Telescopic Pipes is equipped with the Eye-let Lock. The Telescopic Pipes are attached on a Dial on which they can be locked at any angle and direction over the surface of the vehicle. The Dial is fixed on the vinyl-coated Metallic Plate, which is secured by means of screws and slide-able tension adjuster equipped with the vinyl-coated wire pulling the Metallic Plates toward each other. The Fabric along with Lids can be dumped into the truck of the vehicle and the Telescopic Pipes can be collapsed, if shade is not desired.

       BACKGROUNG OF THE INVENTION  
       [0002]     This invention of Collapsible Car Sun Shade can be categorized in the field of consumer products. In summer everyone wants to park their vehicle under the shade, either of tree or building, in order to protect him or herself with damaging sunlight exposure. Parking lots of almost all the departmental stores, malls, shopping plazas, roadside businesses, schools, hospitals &amp; clinics, apartment complexes, office buildings, parks, theme parks, cinemas, and other public and private business places do not have any facility to park the car under the shade. This invention provide handy sun shade any where at any time for any vehicle for not only protecting the consumer from the chances of probable heat stroke due to high temperature inside the vehicle, but also for increasing the fuel efficiency of the vehicle along with car AC&#39;s life.  
         [0003]     The only way to reduce the inside temperature of the vehicle is to have the sufficient gap for flowing air between the top of the surface of the vehicle and the shade. This was being achieved earlier either by assembling bulk structure with excess physical efforts or by time consuming and confusing procedures. This invention overcomes all these difficulties.  
       SUMMARY  
       [0004]     This invention of Car Sun Shade provides totally effortless operation and easy deployment of sunshade in a very little time. Since all the assembly except the fabric sheet, are mounted on a vehicle without effecting the vehicle beautification and cosmetics and without tempering the vehicle body, consumer does not need to waste time in arranging parts before the deployment of sun shade and placing suction or weighted objects, tighten loops or screws after the deployment of the Sun Shade. The consumer is also free from the fear of stealing of assembly mounted on a vehicle as it cannot be removed until the car is unlocked. The Consumer has also the piece of mind that the assembly and the Sun Shade have all possible protective measures to avoid the damage of any kind to the vehicle due to air turbulence. The consumer also saves time in removing the Sun Shade without any physical effort.
