Apparatus for tile leveling and spacing

Abstract

A leveling spacer may include a base, a connecting piece having a breakage portion, a threaded shaft and a pressure applicator. In one embodiment, the breakage portion of the connecting piece is disposed at right angles to the base, and the other end thereof is connected with the threaded shaft. The pressure applicator is configured to engage and remove the threaded shaft, and more specifically, the pressure applicator may include a female threaded chamber to correspondingly engage with the threaded shaft. When the pressure applicator is rotated down the shaft, it can also apply pressure to level and immobilize the substrate.

What is claimed is: 
     
         1 . A leveling spacer comprising:
 a base to be inserted underneath one or more substrates;   a connecting piece having one end, which is a breakage portion, extending from the base at right angle;   a threaded shaft vertically connected to the other end of the connecting piece; and   a pressure applicator configured to engage with the threaded shaft through a corresponding female threaded chamber to rotate and apply pressure to level and immobilize the substrates;   wherein the pressure applicator can be further rotated at the end of the threaded shaft to provide an external force to cause the breakage of the connecting piece on the base, so the connecting piece along with the threaded shaft are removed from the leveling spacer.   
     
     
         2 . The leveling spacer of  claim 1 , wherein the pressure applicator includes one or more guiding channels to guide different types of connecting pieces along with the threaded shafts out of the pressure applicator after being removed from the base. 
     
     
         3 . The leveling spacer of  claim 1 , wherein threaded shaft includes a top edge having a predetermined angle to allow the pressure applicator to easily insert and remove from the shaft, and the pressure applicator has a guiding surface configured to guide the top edge into the female threaded chamber. 
     
     
         4 . The leveling spacer of  claim 2 , wherein threaded shaft includes a top edge having a predetermined angle to allow the pressure applicator to easily insert and remove from the shaft, and the pressure applicator has a guiding surface configured to guide the top edge into the female threaded chamber. 
     
     
         5 . The leveling spacer of  claim 1 , wherein the pressure applicator is made of Nylon and glass fiber.
