Cellphone protector

Abstract

A cellphone protector for protecting a portable appliance having a screen, the protector comprising: a cellphone protection mechanism; a protection-requirement detection mechanism adapted to actuate the cellphone protection mechanism; and a housing for housing the cellphone protection mechanism and the protection-requirement detection mechanism. The cellphone protection mechanism comprises: at least one screen protection shutter adapted to cover and uncover the screen and provide protection thereto; and a shutter opening and closure mechanism operably connected to the at least one shutter and adapted to open and close the at least one shutter for respectively uncovering and covering the screen. The protection-requirement detection mechanism is adapted to detect whether or not there is an object adjacent the protection-requirement detection mechanism, and adapted to actuate the shutter opening and closure mechanism of the cellphone protection mechanism.

What is claimed is: 
     
         1 . A cellphone protector for protecting a portable appliance having a screen, the protector comprising:
 a cellphone protection mechanism;   a protection-requirement detection mechanism adapted to actuate the cellphone protection mechanism; and   a housing for housing the cellphone protection mechanism and the protection-requirement detection mechanism,   wherein the cellphone protection mechanism comprises:
 at least one screen protection shutter adapted to cover and uncover the screen and provide protection thereto; and 
 a shutter opening and closure mechanism operably connected to the at least one shutter and adapted to open and close the at least one shutter for respectively uncovering and covering the screen; 
   and the protection-requirement detection mechanism is adapted to detect whether or not there is an object adjacent the protection-requirement detection mechanism, and adapted to actuate the shutter opening and closure mechanism of the cellphone protection mechanism.   
     
     
         2 . The protector according to  claim 1 , wherein the shutter opening and closure mechanism comprises: a winding wheel; a shutter winding shaft associated with the winding wheel; a solenoid operably connected to the winding wheel; a shutter closure shaft; a shutter retraction spring associated with the shutter closure shaft; and a micro-processor adapted to receive a signal from the detection protection-requirement detection mechanism and operably connected to the solenoid. 
     
     
         3 . The protector according to  claim 1 , wherein the shutter opening and closure mechanism comprises: a shutter opening motor;
 a shutter winding shaft associated with the shutter opening motor; a shutter closure shaft; a spring associated with the shutter closure shaft; a micro-processor adapted to receive a signal from the detection protection-requirement detection mechanism and operably connected to the shutter opening motor; and a shutter closure spring associated with shutter closure shaft.   
     
     
         4 . The protector according to  claim 1 , wherein the shutter opening and closure mechanism comprises: a shutter opening motor; a shutter closure motor; shutter winding shaft associated with the shutter opening motor; a shutter closure shaft associated with the shutter closure motor; a micro-processor adapted to receive a signal from the detection protection-requirement detection mechanism and operably connected to the shutter opening motor and the shutter closure motor. 
     
     
         5 . The protector according to  claim 1 , further comprising at least one track for guiding the shutter. 
     
     
         6 . The protector according to  claim 1 , wherein the protection-requirement detection mechanism comprises a circuit including adjacent serpentine wires. 
     
     
         7 . The protector according to  claim 1 , wherein the protection-requirement detection mechanism comprises a distance sensor for detecting the object adjacent the protection-requirement detection mechanism. 
     
     
         8 . The protector according to  claim 1 , wherein the protection-requirement detection mechanism comprises both a circuit and a distance sensor. 
     
     
         9 . The protector according to  claim 1 , wherein the protection-requirement detection mechanism comprises at least one contact and the housing is adapted to be moveable to press on the at least one contact as a result of the protector being held by a user, to close a circuit. 
     
     
         10 . The protector according to  claim 1 , wherein the shutter comprises upper and lower shutter pulling strips defining upper and lower borders of an open area, which substantially corresponds to the screen area.
