Protective cover unfolding and positioning device

Abstract

A protective cover unfolding and positioning device has a position restoring element installed at a folding portion adjacent to upper and lower support portions of a first protective plate for providing a restoring resilience for bending or folding the upper and lower support portions. A telecommunication product or an electronic device may be disposed obliquely on a peripheral surface of a second protective plate peripheral surface, The weight of the telecommunication product or electronic device exerted on the first protective plate upper, the lower support portions and the restoring resilience provided by the position restoring element to the upper and lower support portions Maintain stability of the that the telecommunication product or electronic device.

What is claimed is: 
     
         1 . A protective cover unfolding and positioning device, comprising a first protective plate and a second protective plate coupled with each other and foldable and unfoldable with respect to each other, and the first protective plate being provided for accommodating a telecommunication product or an electronic device, and having a transverse folding portion disposed on a peripheral surface of the first protective plate for dividing the first protective plate into an upper support portion and a lower support portion; characterized in that a position restoring element is installed at a position of folding portion adjacent to the upper and lower support portions of the first protective plate, and the position restoring element provides a restoring resilience for bending and folding the upper and lower support portions by using the folding portion as a base. 
     
     
         2 . The protective cover unfolding and positioning device of  claim 1 , wherein the position restoring element is made of an elastic material with a position restoring effect selected from the collection of polyurethane (PU), thermoplastic polyurethane elastomer (TPU), thermoplastic elastomer (TPE), synthetic rubber and rubber. 
     
     
         3 . The protective cover unfolding and positioning device of  claim 1 , wherein the position restoring element comes with a quantity of one and is installed at a position of the folding portion adjacent to the upper and lower support portions of the first protective plate. 
     
     
         4 . The protective cover unfolding and positioning device of  claim 1 , wherein the position restoring elements come with a plural quantity and a shorter length and are installed at positions of the folding portion adjacent to the upper and lower support portions of the first protective plate. 
     
     
         5 . The protective cover unfolding and positioning device of  claim 1 , wherein the position restoring element is installed at a position of the folding portion adjacent to the upper and lower support portions of the first protective plate by an adhesion, sewing or riveting method. 
     
     
         6 . The protective cover unfolding and positioning device of  claim 1 , wherein the position restoring element is covered by an inside material and a decorative outside material of the inner and outer surfaces of the upper and lower support portions of the first protective plate and sheltered into a hidden form. 
     
     
         7 . The protective cover unfolding and positioning device of  claim 1 , wherein the position restoring element is covered onto the first protective plate, and the inside material and decorative outside material of the inner and outer surfaces of the upper and lower support portions are covered and sheltered into a hidden form, and both sides of the position restoring element are coupled to the upper and lower support portions. 
     
     
         8 . The protective cover unfolding and positioning device of  claim 1 , wherein the position restoring element is installed on an inner peripheral surface or an outer periphery surface of the folding portion adjacent to the upper and lower support portions of the first protective plate. 
     
     
         9 . The protective cover unfolding and positioning device of  claim 1 , wherein the position restoring element is installed on an inner peripheral surface or a periphery surface of the folding portion adjacent to the upper and lower support portions of the first protective plate. 
     
     
         10 . The protective cover unfolding and positioning device of  claim 6 , wherein the inside material and the decorative outside material of the inner and outer surfaces of the upper and lower support portions of the first protective plate are cloth or leather.
