Door apparatus

Abstract

A multi-piece door assembly including a first door portion and a second door portion, which are removable to create a partially open-air experience or fully open-air experience. A pin pocket design is provided for selectively attaching the first door portion to a variety of different types of second door portions. A blow-out tab is provided to keep the multi-piece door assembly from blowing outwardly away from the vehicle with the increase of internal pressures at high speeds or crosswind situations.

         2 . The two-piece door assembly of  claim 1 , wherein at least the first door portion is removable from the vehicle to create a partially open-air experience. 
     
     
         3 . The two-piece door assembly of  claim 1 , wherein the vehicle is an off-road vehicle or utility task vehicle. 
     
     
         4 . The two-piece door assembly of  claim 1 , wherein the plurality of attachment portions are pin pocket designs. 
     
     
         5 . The two-piece door assembly of  claim 4 , wherein the plurality of attachment portions each include an attachment member operably connected to one of the first or second door portions and each include a fastener member operably connected to the other of the first or second door portion. 
     
     
         6 . The two-piece door assembly of  claim 5 , wherein the fastener member is a pin which is received within the pin pocket design. 
     
     
         7 . The two-piece door assembly of  claim 6 , wherein the attachment member is a pin pocket, and, the pin is received and held within the pin pocket. 
     
     
         8 . The two-piece door assembly of  claim 6 , wherein the attachment member is a clamp that receives the pin and is operably connected to one of the first or second door portions. 
     
     
         9 . The two-piece door assembly of  claim 8 , further comprising a tube section, wherein the clamp straddles the tube section to secure the tube section against the one of the first or second door portions. 
     
     
         10 . The two-piece door assembly of  claim 1 , further comprising at least one mounting bracket operable to connect to one of the first or second door portions and to the plurality of attachment portions for connect the plurality of attachment portions to the one of the first or second door portions. 
     
     
         11 . The two-piece door assembly of  claim 1 , further comprising at least one blow-out tab that engages the vehicle structure to keep the two-piece door assembly from pulling away from the vehicle with increased internal pressures at higher speeds or crosswinds. 
     
     
         12 . The two-piece door assembly of  claim 11 , wherein each of the at least one blow-out tabs is welded to the first and/or second door portions. 
     
     
         13 . The two-piece door assembly of  claim 1 , wherein the vehicle is a 4-door or 2-door sport utility vehicle. 
     
     
         14 . The two-piece door assembly of  claim 1 , wherein the first and/or second door portions include a wire frame. 
     
     
         15 . The two-piece door assembly of  claim 14 , further comprising at least one blow-out tab welded to a wire frame of the first and/or second door portions include a wire frame to keep the door assembly from blowing outwardly under higher speeds or crosswinds. 
     
     
         16 . The two-piece door assembly of  claim 1 , further comprising a door frame including an upper frame with at least one bracket, wherein said bracket is operably connected to a vehicle frame. 
     
     
         17 . A multi-piece door assembly for a motor vehicle, comprising
 a first door half having a plurality of fastener members;   a second door half having a plurality of cooperating attachment members selectively coupled to the plurality of fastener members, wherein said second door half is selectively removable from the motor vehicle when desired; and,   at least one blow-out tab that engages the vehicle structure to keep the two-piece door assembly from pulling away from the vehicle with increased internal pressures at higher speeds or crosswinds.   
     
     
         18 . The multi-piece door assembly of  claim 17 , wherein the plurality of attachment members are pin pockets that receive a respective pin. 
     
     
         19 . The multi-piece door assembly of  claim 18 , further comprising a plurality of mounting brackets operably coupled to the plurality of attachment members, respectively, said plurality of mounting brackets operably connected to a second frame assembly of the first door half. 
     
     
         20 . A multi-piece door assembly for a motor vehicle, comprising
 an upper door portion having a plurality of fastener members;   a lower door portion having a plurality of mounting plates operably connected to a plurality of receiving members, respectively, wherein said plurality of fastener members are selectively slidably received within respective receiving members to connect said upper and lower door portions together;   at least one blow-out tab operably connected to said upper door portion and, when in the motor vehicle installed position, is immediately adjacent a rollover protective structure of said motor vehicle to prevent the multi-piece assembly from pulling outward from the motor vehicle by vacuum generated by airflow.
