Clip for cast stone wall system

Abstract

A tenon clip for affixing cast stone elements to a supporting wall surface having a U-shaped fastening portion with a first fastening side and opposing sidewalls generally perpendicular to the first fastening side. An anchoring flange extends from each of the sidewalls. The first fastening side has a fastening aperture therethrough for fastening the tenon clip to the supporting wall surface. Each anchoring flange has one or more anchors to secure the tenon clip within the cast stone element.

What is claimed is: 
     
         1 . A tenon clip for affixing cast stone elements to a supporting wall surface, comprising a U-shaped fastening portion with a first fastening side and opposing sidewalls generally perpendicular to the first fastening side and an anchoring flange extending from each of the sidewalls, wherein the first fastening side has a fastening aperture therethrough for fastening the tenon clip to the supporting wall surface and, wherein each anchoring flange has one or more anchors to secure the tenon clip within the cast stone element. 
     
     
         2 . The tenon clip of  claim 1 , wherein the one or more anchors comprises one or more apertures through the anchoring flanges. 
     
     
         3 . The tenon clip of  claim 2 , wherein the one or more anchors comprises a tab extending generally perpendicularly from the anchoring flanges. 
     
     
         4 . The tenon clip of  claim 3 , wherein the tenon clip has a length and the cast stone element has a height separating the opposing top and bottom edges and, wherein the length of the tenon clip is greater than the height of the cast stone element. 
     
     
         5 . The tenon clip of  claim 4 , wherein the fastening aperture is located adjacent one end of the first fastening side and a second fastening aperture is located adjacent the opposing end of the first fastening side. 
     
     
         6 . The tenon clip of  claim 5 , wherein the anchoring flanges have a length substantially equal to the height of the cast stone element and, wherein the tabs are positioned at the top and bottom edges of the cast stone element. 
     
     
         7 . A cast stone wall system, comprising:
 a supporting wall surface;   a cast stone element having a decorative face, a rear face opposite the decorative face, a top edge, and a bottom edge; and   a tenon clip having a U-shaped fastening portion with a first fastening side and opposing sidewalls generally perpendicular to the first fastening side and an anchoring flange extending from each of the sidewalls and is at least partially embedded in the rear face of the cast stone element, wherein the first fastening side has a fastening aperture therethrough for fastening the tenon clip to the supporting wall surface and, wherein each anchoring flange has one or more anchors to secure the tenon clip within the cast stone element.   
     
     
         8 . The cast stone wall system of  claim 7 , wherein the one or more anchors comprises one or more apertures through the anchoring flanges. 
     
     
         9 . The cast stone wall system of  claim 8 , wherein the one or more anchors comprises a tab extending generally perpendicularly from the anchoring flanges. 
     
     
         10 . The cast stone wall system of  claim 9 , wherein the tenon clip has a length and the cast stone element has a height separating the opposing top and bottom edges and, wherein the length of the tenon clip is greater than the height of the cast stone element. 
     
     
         11 . The cast stone wall system of  claim 10 , wherein the fastening aperture is located adjacent one end of the first fastening side and a second fastening aperture is located adjacent the opposing end of the first fastening side. 
     
     
         12 . The cast stone wall system of  claim 11 , wherein the anchoring flanges have a length substantially equal to the height of the cast stone element and, wherein the tabs are positioned at the top and bottom edges of the cast stone element.
