Modular half door

Abstract

A side door assembly is provided for an automotive vehicle body having a side opening. The side door assembly includes a one-piece casting for hinged connection to the vehicle body. The casting forms a frame. At least one panel insert is selectively connected from the interior of the vehicle outward by a plurality of rotary attachment features to the frame. The frame includes a plurality of reinforcement features to add structure and rigidity, while reducing weight, to the side door assembly.

         7 . The door assembly described in  claim 1 , wherein the frame includes a plurality of reinforcement features to add structure and rigidity, while reducing weight of said side door assembly. 
     
     
         8 . The door assembly of  claim 1 , wherein said door is a half door. 
     
     
         9 . The door assembly of  claim 1 , wherein said door is a full door. 
     
     
         10 . The door assembly of  claim 1 , wherein said frame also mounts a rear view mirror. 
     
     
         11 . The door assembly of  claim 1 , further comprising a door paddle latch. 
     
     
         12 . The door assembly of  claim 1 , wherein an operating cable for said door latch is operably connected to said frame and operably routed to a door paddle latch mechanism. 
     
     
         13 . The door assembly of  claim 1 , further comprising a window frame connected to said side door assembly. 
     
     
         14 . The door assembly of  claim 1 , further comprising a plurality of structural reinforcements that are strengthening ribs, wherein said strengthening ribs extend from a wall forming said opening outward to an outer wall of said frame. 
     
     
         15 . The door assembly of  claim 1 , wherein said rotary attachment features are toggles. 
     
     
         16 . The door assembly of  claim 1 , wherein said at least one inner panel is transparent. 
     
     
         17 . A side door assembly for a vehicle body having a side opening, said side door assembly comprising:
 a door frame operably hinged to the vehicle body;   an opening defined by a wall of said one-piece door frame; and   at least one panel insert selectively attached to said frame of the side door assembly by a plurality of attachments to selectively attach the at least one insert panel to said frame to close off said opening.   
     
     
         18 . The door assembly described in  claim 17 , wherein said plurality of attachments are rotary selectively coupling said at least one insert panel to said one-piece frame to close off said opening. 
     
     
         19 . The door assembly of  claim 17 , further comprising a plurality of structural reinforcements that are strengthening ribs integrated with said frame, wherein each of said strengthening ribs extend outward from said wall defining said opening. 
     
     
         20 . The door assembly of  claim 17 , wherein said at least one inner panel is transparent. 
     
     
         21 . A side door assembly for a vehicle body having a side vehicle opening, said side door assembly comprising:
 a door frame operably connected to the vehicle body and operable to open/close said side vehicle opening;   an opening provided through said door frame;   at least one panel insert pressed against said door frame over top said opening and selectively held in place against said door frame of said side door assembly by a plurality of attachments to selectively attach said at least one insert panel over said opening closing off said opening, and wherein selectively releasing said plurality of attachments allows said at least one insert panel to be removed from over said opening to open up said opening to the outside environment when an open air experience is desired.
