Abstract

A tile positioning device comprising: a base having a top surface for receiving an underside of a tile and a bottom surface for being positioned on an underlying surface; an upwardly extending stem that is breakably or frangibly attached to the base, the stem including an upper portion for receiving an impact to break away the stem from the base and a lower portion for breakable attachment to the base wherein an opening is provided in the lower portion of the stem for receiving a wedge and wherein the lower portion of the stem further comprises: a connecting portion for connecting the stem with the top surface of the base; and a bridging portion extending between the connecting portion and the upper portion; wherein thickness of the connecting portion is less than thickness of the bridging portion.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A tile levelling device comprising:
 a base having a top surface for receiving an underside of a tile and a bottom surface for being positioned on an underlying surface;   an upwardly extending stem that is breakably or frangibly attached to the base, the stem including an upper portion for receiving an impact to break away the stem from the base and a lower portion for breakable attachment to the base wherein an opening is provided in the lower portion of the stem for receiving a wedge and wherein the lower portion of the stem further comprises: a connecting portion for connecting the stem with the top surface of the base; and a bridging portion extending between the connecting portion and the upper portion; wherein thickness of the connecting portion is less than thickness of the bridging portion.   
     
     
         2 . A tile levelling device in accordance with  claim 1  wherein length of the connecting portion is less than the length of bridging portion. 
     
     
         3 . A tile levelling device in accordance with  claim 1  wherein height of the connecting portion is substantially less than height of the connecting portion. 
     
     
         4 . A tile levelling device in accordance with  claim 3  comprising at least two of said lower portions being spaced apart to provide the opening below the upper portion. 
     
     
         5 . A tile levelling device in accordance with  claim 4  wherein each of the bridging portions includes opposed edges extending along a length of the bridging portion and wherein the connecting portion extends downwardly and inwardly relative to the opposed edges of the bridging portion to breakably attach to the top surface of the base. 
     
     
         6 . A tile levelling device in accordance with  claim 4  wherein the top surface of the base extends in between the two lower portions of the stem. 
     
     
         7 . A tile levelling device in accordance with  claim 1  wherein the upper portion has a thickness that is greater than thickness of the bridging portion in the lower portions of the stem. 
     
     
         8 . A tile levelling device in accordance with  claim 1  wherein the connecting portion comprises a tapered configuration. 
     
     
         9 . A tile levelling device in accordance with  claim 1  wherein thickness of the connecting portion decreases gradually in a downward direction towards the base. 
     
     
         10 . A tile levelling device in accordance with  claim 1  wherein the bridging portion comprises one or more rounded edge portions extending from one or both of said opposed edges of the bridging portions towards the adjacently located connecting portion. 
     
     
         11 . A tile levelling device in accordance with  claim 1  wherein the upper portion comprises a recessed channel extending along a length of the upper portion. 
     
     
         12 . A tile levelling device in accordance with  claim 1  wherein height of the upper portion is greater than or equal to height of the bridging portion. 
     
     
         13 . A tile levelling device in accordance with  claim 4  wherein the top surface of the base extends in between the two lower portions of the stem.
