Air register

Abstract

An air register is described in which top and bottom panels are disposed to opposed sides of a central grid. The grid includes at least one open ended cell formed by wall members that extending between the top and bottom panels. The top panel includes a top opening in open communication with the cell and adjacent one wall member of the grid. The bottom panel includes a bottom opening in open communication with the cell adjacent another wall member of the grid.

1 . An air register, comprising: 
 a top panel having a top surface and an opposed bottom surface, and having top openings extending between the top and bottom surfaces;    an air transmission grid with top and bottom grid surfaces, including a plurality of individual cells formed by cell walls, at least some of which open along grid top and bottom surfaces;    the grid being joined to the bottom surface of the top panel such that at least some of the cells open into the openings;    a bottom panel having an upper surface and an opposed lower surface and having bottom openings extending between the upper and lower surfaces;    wherein the bottom panel is joined to the grid along the bottom grid surface; and    wherein the bottom and top openings are offset to opposed sides of associated cells.    
     
     
         2 . The register of  claim 1  wherein the openings are elongated, with each opening overlapping a plurality of cells.  
     
     
         3 . The register of  claim 1  wherein open ends of the cells are of greater dimension than the top and bottom openings.  
     
     
         4 . The register of  claim 1  wherein the grid is a rectangular grid.  
     
     
         5 . The register of  claim 1  wherein the grid is a rectangular grid and the cells are of rectangular cross section.  
     
     
         6 . The register of  claim 1  wherein the top and bottom panels are flat and planar.  
     
     
         7 . The register of  claim 1 , further comprising a joining bracket mechanically connecting the panels and grid together.  
     
     
         8 . The register of  claim 1 , further comprising a joining bracket, connecting the top and bottom panels on opposed sides of the grid.  
     
     
         9 . The register of  claim 1 , wherein the grid is comprised of square cells.  
     
     
         10 . The register of  claim 9  wherein the bottom openings are elongated and span a plurality of said cells.  
     
     
         11 . The register of  claim 10  wherein top openings are elongated and span a plurality of said cells.  
     
     
         12 . The register of  claim 11  wherein the elongated openings include width dimensions and the cells include cell width dimensions, and wherein the cell width dimensions are greater than the width dimensions of the openings.  
     
     
         13 . The register of  claim 1  wherein the cells include cell walls that are at least substantially perpendicular to the upper surface of the bottom panel.  
     
     
         14 . The register of  claim 13  wherein the cell walls are at least substantially perpendicular to the bottom surface of the top panel.  
     
     
         15 . An air register, comprising: 
 a laminated body including top and bottom panels on opposed sides of a central grid;    wherein the grid includes wall members extending between the top and bottom panels and arranged to form at least one open ended cell;    wherein the top panel includes a top opening in open communication with the cell adjacent one wall member of the grid and the bottom panel includes a bottom opening in open communication with the cell adjacent another wall member of the grid.    
     
     
         16 . The air register of  claim 15  wherein the wall members are substantially perpendicular to the top and bottom panels.  
     
     
         17 . The air register of  claim 15  wherein the cell is rectangular and the top and bottom openings are situated adjacent opposed walls of the cell.  
     
     
         18 . The air register of  claim 17  wherein the cell includes a width dimension and wherein the top and bottom openings each include width dimensions that are less than the cell width dimension.  
     
     
         19 . The air register of  claim 18  wherein the top and bottom opening width dimensions are less than one half the width dimension of the cell.  
     
     
         20 . The air register of  claim 15  further comprising a bracket joining the top and bottom panels on opposed sides of the grid.
