Shielding device for vehicle while opening the door

Abstract

A shielding device for shielding a space between a door and an object when the door is opened, includes two seats, a spool rotatably secured between the seats with a shaft and having a frustum shape, and a sector shield having one side edge secured to the spool and to be wound onto or unwound from the spool when the spool is rotated around the shaft. The seats and the other side edge of the shield are secured to the object and the door respectively for allowing the shield to be unwound from the spool to shield the space between the door and the object when the door is opened.

I claim:  
     
         1 . A shielding device for shielding a space formed between a door panel and an object when the door panel is opened relative to the object, said shielding device comprising: 
 a pair of spaced seats,    a shaft disposed between said seats,    a spool rotatably engaged on said shaft, said spool including a first end portion and a second end portion, said first end portion of said spool including an outer diameter smaller than that of said second end portion of said spool, and    a shield including a sector shape having a first side edge secured to said spool, for allowing said spool to be wound onto or unwound from said spool when said spool is rotated around said shaft, and said shield including a second side edge,    said seats and said second side edge of said shield being provided for securing to the object and the door panel respectively for allowing said shield to be unwound from said spool to shield the space formed between the door panel and the object when the door panel is opened relative to the object.    
     
     
         2 . The shielding device according to  claim 1 , wherein said spool includes a slit formed therein for receiving said first side edge of said shield and for allowing said first side edge of said shield to be secured to said spool.  
     
     
         3 . The shielding device according to  claim 2 , wherein said spool includes a longitudinal passage formed therein, and a rod engaged in said longitudinal passage of said spool and secured to said first side edge of said shield.  
     
     
         4 . The shielding device according to  claim 3 , wherein said first side edge of said shield includes a sleeve provided therein for receiving said rod.  
     
     
         5 . The shielding device according to  claim 3 , wherein said spool includes a recess formed in said second end portion thereof and communicating with said longitudinal passage of said spool, and a bearing received in said recess of said spool and secured to said spool, for retaining said rod in said longitudinal passage of said spool.  
     
     
         6 . The shielding device according to  claim 1  further comprising means for recovering said spool after said spool is released.  
     
     
         7 . The shielding device according to  claim 6 , wherein said recovering means includes a spring secured between said spool and said shaft.  
     
     
         8 . The shielding device according to  claim 7 , wherein said spring is a coil spring engaged onto said shaft, and includes a first end secured to said shaft and a second end for securing to said spool.  
     
     
         9 . The shielding device according to  claim 8 , wherein said shaft includes a peripheral bulge extended radially outward therefrom, said coil spring includes a portion force-fitted onto said peripheral bulge of said shaft.  
     
     
         10 . The shielding device according to  claim 7 , wherein said spool includes a recess formed in said second end portion thereof, and a bearing received in said recess of said spool and secured to said spool and rotated in concert with said spool, said spring includes a first end secured to said bearing.  
     
     
         11 . The shielding device according to  claim 1 , wherein said spool includes a peripheral bead extended radially outward from said first end portion of said spool, and a peripheral stop extended radially outward from said second end portion of said spool, for retaining said shield on said spool.  
     
     
         12 . The shielding device according to  claim 1 , wherein said shield includes an outer peripheral portion, said spool includes a peripheral groove formed in said second end portion thereof for receiving said outer peripheral portion of said shield and for positioning said shield relative to said spool.  
     
     
         13 . The shielding device according to  claim 1 , wherein said spool includes a hollow structure having a peripheral chamber formed therein and having at least one reinforcing partition provided therein for reinforcing said spool.
