Grating

Abstract

The invention relates to a grating consisting of parallel bearing bars connected by cross bars running perpendicular to the bearing bars, and of a frame, sheet-metal strips being located between the bearing bars. In order to improve a grating of this kind in such manner that it is easier to manufacture, it is suggested within the scope of the invention that a wire be inserted under each of the cross bars and the sheet-metal strip clamped between the wires and the cross bars.

1 . A grating consisting of parallel bearing bars connected by cross bars running perpendicular to the bearing bars, and of a frame, sheet-metal strips being located between the bearing bars, wherein a wire ( 6 ) is inserted under each of the cross bars ( 2 ) and the sheet-metal strip ( 4 ) is clamped between the wires ( 6 ) and the cross bars ( 2 ). 
   
   
       2 . The grating of  claim 1 , wherein the cross bars ( 2 ) consist of flat material. 
   
   
       3 . The grating of  claim 2 , wherein the cross bars ( 2 ) and the bearing bars ( 1 ) are press locked. 
   
   
       4 . The grating of  claim 1 , wherein the frame ( 3 ) is of T-shape configuration. 
   
   
       5 . The grating of  claim 1 , wherein the sheet-metal strips ( 4 ) have perforations ( 5 ). 
   
   
       6 . The grating of  claim 5 , wherein each sheet-metal strip ( 4 ) has two rows of square perforations ( 5 ).
