Rigid plastic door with slatted vane construction

Abstract

Extruded plastic doors having two side stiles and a top and bottom rail forming a generally rectangular configuration and having horizontal vanes covering the interior of the door. The stiles have mating indentations along their interior edge for receiving the vanes and holding the vanes in a permanently fixed position relative to the stiles and rails when the stiles and rails are assembled into a rectangular configuration. The stiles, rails and vanes are formed by an extrusion process so as to have a substantially hollow interior with reinforcing cross-members.

I claim:  
     
         1 . A synthetic resinous plastic door having a generally rectangular configuration comprising two vertical side stiles, and a top and bottom horizontal rail defining the perimeter of the door, and vanes covering the interior of the rectangular configuration, the stiles having indentations along their interior edge for receiving the vanes so as to hold the vanes in a permanently fixed position relative to the stiles and rails when the stiles and rails are assembled into a rectangular configuration, and the stiles, rails and vanes being formed by an extrusion process and having a substantially hollow interior with reinforcing cross-members, wherein the two panels of the door are attached to each other by a first hinge to permit folding of the door and one of the panels is attached to a door frame by a second hinge.  
     
     
         2 . The door of  claim 1  further comprising a middle horizontal rail.  
     
     
         3 . The door of  claim 1  wherein the foamed plastic comprises about 65% to 75% PVC, about 12% to 18% calcium carbonate, about 8% to 12% stabilizer, and about 3% to 7% titanium dioxide.  
     
     
         4 . The door of  claim 3  wherein the foamed plastic comprises about 70% PVC, about 15% calcium carbonate, about 10% stabilizer, and about 5% titanium dioxide.  
     
     
         5 . A synthetic resinous plastic door comprising two panels, each having a generally rectangular configuration comprising two vertical side stiles, and atop and bottom horizontal rail defining the perimeter of the door, and vanes covering the interior of the rectangular configuration, the stiles having mating indentations along their interior edge for receiving the vanes so as to hold the vanes in a permanently fixed position relative to the stiles and rails when the stiles and rails are assembled into a rectangular configuration, and the stiles, rails and vanes being formed by an extrusion process and having a substantially hollow interior with reinforcing cross-members, wherein the two panels of the door are each attached a door frame by a hinge to permit the panels to open from the middle.  
     
     
         6 . The door of  claim 5  further comprising a middle horizontal rail.  
     
     
         7 . The door of  claim 5  wherein the foamed plastic comprises about 65% to 75% PVC, about 12% to 18% calcium carbonate, about 8% to 12% stabilizer, and about 3% to 7% titanium dioxide.  
     
     
         8 . The door of  claim 7  wherein the foamed plastic comprises about 70% PVC, about 15% calcium carbonate, about 10% stabilizer, and about 5% titanium dioxide.  
     
     
         9 . A synthetic resinous plastic door having a generally rectangular configuration comprising two vertical side stiles, and a top and bottom horizontal rail defining the perimeter of the door, a vertical center stile and vanes covering the interior of the rectangular configuration, the stiles having mating indentations along their interior edge for receiving the vanes so as to hold the vanes in a permanently fixed position relative to the stiles and rails when the stiles and rails are assembled into a rectangular configuration, and the stiles, rails and vanes being formed by an extrusion process and having a substantially hollow interior with reinforcing cross-members.  
     
     
         10 . The door of  claim 9  further comprising a middle horizontal rail.  
     
     
         11 . The door of  claim 9  wherein the foamed plastic comprises about 65% to 75% PVC, about 12% to 18% calcium carbonate, about 8% to 12% stabilizer, and about 3% to 7% titanium dioxide.  
     
     
         12 . The door of  claim 9  wherein the foamed plastic comprises about 70% PVC, about 15% calcium carbonate, about 10% stabilizer, and about 5% titanium dioxide.
