Vehicle self-collapsible cover

Abstract

The present invention discloses a vehicle self-collapsible cover including generally a protective awning, an extension-structure, and a storage-case. The protective awning comprises two or four rolls of thin and tough material able to substantially cover the vehicles body. The extension-structure is driven by a central-lead-screw having two kinds of thread including right-handed thread and left-handed thread so as to be able to extend said rolls of awning. In one embodiment of the invention, the device is divided into two symmetrical halves joined together by a hinge and therefore foldable. Each half of the storage-case is supported by its own supporting structures and respectively capable to store two rolls of awning and one extension-structure. In another embodiment of the invention, the device is one unit which is assembled either fixedly by clamping or actively by screws on the top of vehicle. The self-collapsible cover may be operated manually or by motors. It also can be controlled by a remote.

1 . A self-collapsible cover for a vehicle body comprising: 
 a) a protective awning is divided into four rolls able to substantially cover a vehicle body, in which each roll has one or more ring-springs mounted inside to keep it tensioned all the time; and    b) an extension structure able to extend said four rolls of awning comprising: 
 i) four extension-racks, in which each comprises a main-rack and a sub-rack which is joined to the main-rack by a joining structure; and  
 ii) a central-lead-screw being divided into two halves respectively having right-handed thread and left-handed thread; and  
 iii) two main-moving-pivots; and  
 iv) four sub-moving-pivots; and  
   c) a storage-case being divided into two halves which join together by a hinge to be able to store said four rolls of awnings and said extension structure, and comprising: 
 i) a base-gear, a cable, and reels; and  
 ii) supporting structures including suction-cups and supporting leg;  
   
   
   
       2 . The self-collapsible cover according to  claim 1 , wherein said protective awning is constructed from tough and thin material selected from the group consisting of polyethylene, polystyrene, polyvinylchloride, polyester, gortex, cotton, parachute fabric, or a combination thereof.  
   
   
       3 . The self-collapsible cover according to  claim 1 , wherein said protective awning is made of reflective and water-resistant material.  
   
   
       4 . The self-collapsible cover according to  claim 1 , wherein the rotation of said four rolls of awning is assisted by the rotation of the central-lead-screw by means of gears.  
   
   
       5 . The self-collapsible cover according to  claim 1 , wherein four extra-rolls of coverings are added to expand the ability of the device of the present invention to cover more effectively the sides of vehicle body.  
   
   
       6 . The self-collapsible cover according to  claim 1 , wherein each of said sub-racks is controlled by a sub-moving-pivot which is pulled and pushed by the main-moving-pivot.  
   
   
       7 . The self-collapsible cover according to  claim 6 , wherein the main-moving-pivot pulls the sub-moving-pivot by means of a loop and a spring-tensioned latch.  
   
   
       8 . The self-collapsible cover according to  claim 7 , wherein the spring-tensioned latch slides on a latch-mate pallet.  
   
   
       9 . The self-collapsible cover according to  claim 8 , wherein the latch-mate pallet has a hole for the spring-tensioned latch able to fall into it.  
   
   
       10 . The self-collapsible cover according to  claim 9 , wherein the hole is either non-movable or movable being controlled by a sub-thread-rod.  
   
   
       11 . The self-collapsible cover according to  claim 6 , wherein the main-moving-pivot pushes the sub-moving-pivot right after a wedge raises the spring-tensioned latch up out of the hole.  
   
   
       12 . The self-collapsible cover according to  claim 1 , wherein the hinge of the storage-case is appended with a spring so as to keep the storage-case to be able to fold itself up when the cable is released from the reels.  
   
   
       13 . The self-collapsible cover according to  claim 1 , wherein the foldable-storage case is equipped with a pair of V-shaped springs to make an angle between two halves of the storage-case so as to facilitate the cable to pull and open the foldable-storage case.  
   
   
       14 . The self-collapsible cover according to  claim 1 , wherein the foldable-storage case is secured by a spring-tensioned and tough-material anti-theft straps with hooks.  
   
   
       15 . The self-collapsible cover according to  claim 1 , further comprising a rotating means able to rotate the base-gear.  
   
   
       16 . The self-collapsible cover according to  claim 1 , further comprising a rotating means able to rotate the central-lead-screw.  
   
   
       17 . A self-collapsible cover for a vehicle body comprising: 
 a) a protective awning is divided into two rolls able to substantially cover a vehicle body, in which each roll has one or more ring-springs mounted inside to keep it tensioned all the time; and    b) an extension structure able to extend said two rolls of awning comprising: 
 i) two extension-racks, in which each comprises a main-rack and a sub-rack which is joined to the main-rack by a joining structure; and  
 ii) a central-lead-screw having right-handed thread and left-handed thread; and  
 iii) two main-moving-pivots; and  
 iv) four sub-moving-pivots; and  
   c) a storage-case being able to store said two rolls of awnings and said extension structure.    
   
   
       18 . The self-collapsible cover according to  claim 17 , wherein the self-collapsible cover is assembled fixedly on the top of vehicle by a fixing structure, for example, but not limited to, a clamping.  
   
   
       19 . The self-collapsible cover according to  claim 17 , wherein the self-collapsible cover is assembled actively in a groove on the top of vehicle by a mounting structure, for example, but not limited to, screws.
