Vent With Attached Screen

Abstract

An open ended box having a louvered panel, side panels and top and bottom panels extending from edges of the louvered panel defines a vent for use in a concrete block wall, brick wall or concrete wall. A screen of sheet metal with punched apertures is secured within the vent adjacent the interior surface of the louvered panel. The open end of the vent may be covered with a louvered panel or panel for supporting duct work extending from the vent. Right angle flanges may extend from the sides and bottom of the vent to position the vent in spaced relationship with adjacent elements of the wall and accommodate placement of grout therebetween. A nail or screw extending through each of the side panels adjacent elements of the wall may be used to positionally secure the vent. Flanges extending from the edges of the vent opening serve to be placed adjacent corresponding surfaces of the wall in which the vent is located.

1 . A screened louvered vent comprising in combination:
 a) an open ended box defining a louvered panel, left and right side panels and top and bottom panels;   b) a screen unit includes a panel of punched apertures and flanges extending therefrom for attachment to the inside surface of selected ones of said side panels and said top and bottom panels;   c) said box including side edges defining in part an opening and flanges extending from said side edges; and   d) a panel for covering the opening and including attachment means for securing said panel to said flanges.   
   
   
       2 . The vent as set forth in  claim 1 , including an aperture disposed in each of said side panels for penetrably receiving a nail to be driven into the adjacent surface of a wall in which said vent is to be mounted. 
   
   
       3 . The vent as set forth in  claim 1 , including right angle flanges extending from said side panels for locating said vent within a wall in which said vent is to be mounted. 
   
   
       4 . The vent as set forth in  claim 1 , including right angle flanges extending from said bottom panel for locating said vent within a wall in which said vent is to be mounted. 
   
   
       5 . The vent as set forth in  claim 4 , including right angle flanges extending from said side panels for locating said vent within the wall in which said vent is to be mounted. 
   
   
       6 . The vent as set forth in  claim 1  wherein said flanges of said screen unit extend along and are attached to said left and right side panels of said box. 
   
   
       7 . The vent as set forth in  claim 1  wherein each of said flanges of said screen unit extend along the depth of said top and bottom panels of said vent and including a further flange extending from each of said flanges of said screen unit outwardly from the respective one of said top and bottom panels of said box. 
   
   
       8 . The vent as set forth in  claim 7 , including a first retainer in engagement with said left side panel of said box and each of said further flanges and a second retainer in engagement with said right side panel of said box and each of said further flanges. 
   
   
       9 . The vent as set forth in  claim 1  wherein said box includes a first pair of flanges extending outwardly from the edge of said right side panel defining the opening a further flange disposed intermediate said first pair of flanges and extending inwardly, a second pair of flanges extending outwardly from the edge of said left side panel defining the opening and a yet further flange disposed intermediate said second pair of flanges and extending inwardly. 
   
   
       10 . The vent as set forth in  claim 9  wherein said panel covering the opening is secured to said further and yet further flange. 
   
   
       11 . The vent as set forth in  claim 10  wherein said panel covering the opening is a louvered panel. 
   
   
       12 . The vent as set forth in  claim 10  wherein said panel covering the opening is adapted for supporting duct work. 
   
   
       13 . The vent as set forth in  claim 12  wherein said panel covering the opening includes a lip disposed along each edge. 
   
   
       14 . A method for venting a concrete block wall, a brick wall or a concrete wall, said method comprising the steps of:
 a) placing an open ended box having a louvered panel and a screen unit located adjacent the inside surface of the louvered panel in the wall;   b) driving a nail through at least one side panel of the box into an adjacent element of the wall; and   c) attaching a panel to the open end of the box.   
   
   
       15 . The method as set forth in  claim 14  wherein said step of driving includes the step of driving a nail through opposed side panels of the box into elements of the wall. 
   
   
       16 . The method as set forth in  claim 15  wherein said step of attaching includes the step of securing the panel to flanges extending into the opening of the box. 
   
   
       17 . The method as set forth in  claim 14 , including the step of engaging right angle flanges extending from the bottom of the box with grout. 
   
   
       18 . The method as set forth in  claim 14 , including the step of engaging right angle flanges extending from opposed sides of the box with grout. 
   
   
       19 . The method as set forth in  claim 18 , including the step of engaging right angle flanges extending from the bottom of the box with grout. 
   
   
       20 . The method as set forth in  claim 14 , including the step of forming an opening in the panel to mate with duct work.
