Carpet Cleaning Device

Abstract

A carpet cleaning device includes a rigid liquid lifting sheet that includes a top surface and, opposed, a bottom surface which together extend laterally to side edges and longitudinally from a proximal portion having a liquid lifting edge, to a distal portion that is spaced from the proximal portion. The liquid lifting edge extends laterally between the side edges in an angled configuration that includes at least one vertex which is longitudinally forward of adjacent portions of the liquid lifting edge. A liquid receiver is positioned to receive the liquid that is lifted from the carpet by the liquid lifting edge and the rigid liquid lifting sheet.

What is claimed is: 
     
         1 . A carpet cleaning device for lifting a liquid from a carpet, the carpet cleaning device comprising:
 a rigid liquid lifting sheet that includes a top surface and, opposed, a bottom surface which together extend laterally to side edges and longitudinally from a proximal portion having a liquid lifting edge, to a distal portion that is spaced from the proximal portion;   wherein the liquid lifting edge extends laterally between the side edges in an angled configuration that includes at least one vertex which is longitudinally forward of adjacent portions of the liquid lifting edge; and   a liquid receiver that receives the liquid that is lifted from the carpet by the liquid lifting edge and the rigid liquid lifting sheet.   
     
     
         2 . The carpet cleaning device of  claim 1 , wherein the leading edge is angled downwardly in the direction of the bottom surface of the rigid liquid lifting sheet. 
     
     
         3 . The carpet cleaning device of  claim 1 , further comprising at least one flange extending upwardly from the top surface of the rigid liquid lifting sheet, the at least one flange being disposed longitudinally and extending to the liquid lifting edge. 
     
     
         4 . The carpet cleaning device of  claim 3 , wherein the at least one flange includes a plurality of flanges that are parallel to one another. 
     
     
         5 . The carpet cleaning device of  claim 1 , wherein the liquid lifting edge includes a single vertex, and the adjacent portions are angled to form a triangular shape. 
     
     
         6 . The carpet cleaning device of  claim 1 , wherein the liquid lifting edge includes a plurality of vertices. 
     
     
         7 . The carpet cleaning device of  claim 1 , wherein the liquid receiver is in the form of a reservoir tank mounted adjacent the rigid liquid lifting sheet opposite the liquid lifting edge, the reservoir tank having an opening operably positioned adjacent to a distal end of the rigid liquid lifting sheet. 
     
     
         8 . A carpet cleaning device for lifting a liquid from a carpet, the carpet cleaning device comprising:
 a rigid liquid lifting sheet that includes a top surface and, opposed, a bottom surface which together extend laterally to side edges and longitudinally from a proximal portion having a liquid lifting edge, to a distal portion that is spaced from the proximal portion;   wherein the liquid lifting edge extends laterally between the side edges in an angled configuration that includes at least one vertex which is longitudinally forward of adjacent portions of the liquid lifting edge;   at least one flange extending upwardly from the top surface of the rigid liquid lifting sheet, the at least one flange being disposed longitudinally and extending to the liquid lifting edge; and   a liquid receiver that receives the liquid that is lifted from the carpet by the liquid lifting edge and the rigid liquid lifting sheet.   
     
     
         9 . The carpet cleaning device of  claim 8 , wherein the leading edge is angled downwardly in the direction of the bottom surface of the rigid liquid lifting sheet. 
     
     
         10 . The carpet cleaning device of  claim 8 , wherein the at least one flange includes a plurality of flanges that are parallel to one another. 
     
     
         11 . The carpet cleaning device of  claim 8 , wherein the liquid lifting edge includes a single vertex, and the adjacent portions are angled to form a triangular shape. 
     
     
         12 . The carpet cleaning device of  claim 8 , wherein the liquid lifting edge includes a plurality of vertices. 
     
     
         13 . The carpet cleaning device of  claim 1 , wherein the liquid receiver is in the form of a reservoir tank mounted adjacent the rigid liquid lifting sheet opposite the liquid lifting edge, the reservoir tank having an opening operably positioned adjacent to a distal end of the rigid liquid lifting sheet.
