Tile Leveling System

Abstract

A tile leveling system includes a fixture and a rotary member mounted on the fixture. The fixture includes a base, at least one spacer integrally formed on the base, and a connecting portion formed on the at least one spacer. The at least one spacer is provided with a breaking point. The connecting portion has a top having a central position provided with an internal thread. The connecting portion has two sides each having a top provided with a shoulder. The rotary member is provided with a hollow receiving chamber which has an inner diameter slightly greater than the maximum width defined by an outer edge of the at least one spacer. A threaded rod is mounted in the hollow receiving chamber and is screwed into the internal thread.

1 . A tile leveling system comprising:
 a fixture; and   a rotary member mounted on the fixture;   wherein:   the fixture includes:   a base;   at least one spacer integrally formed on and extending upward from the base; and   a connecting portion formed on and extending upward from the at least one spacer;   the at least one spacer is provided with a breaking point;   the connecting portion has a top having a central position provided with an internal thread;   the connecting portion of the fixture has two sides each having a top provided with a shoulder;   the rotary member is provided with a hollow receiving chamber which has an inner diameter slightly greater than the maximum width defined by an outer edge of the at least one spacer; and   a threaded rod is mounted in the hollow receiving chamber of the rotary member and is screwed into the internal thread of the fixture.   
     
     
         2 . The tile leveling system of  claim 1 , wherein the fixture includes a spacer which is centered at a central point of the base. 
     
     
         3 . The tile leveling system of  claim 1 , wherein the fixture includes a plurality of spacers which are centered at a central point of the base and are equally spaced from each other. 
     
     
         4 . The tile leveling system of  claim 1 , wherein the shoulder of the fixture has an arcuate shape. 
     
     
         5 . The tile leveling system of  claim 1 , wherein:
 the threaded rod has a top provided with a limit portion;   the rotary member has a top provided with a through hole connected to the hollow receiving chamber; and   the through hole of the rotary member has two sides each provided with a locking portion for locking the limit portion of the threaded rod, so that the threaded rod is locked onto the rotary member and extends into the hollow receiving chamber.   
     
     
         6 . The tile leveling system of  claim 1 , wherein the threaded rod and the rotary member are made of plastic material. 
     
     
         7 . The tile leveling system of  claim 1 , wherein the threaded rod and the rotary member are made of different material. 
     
     
         8 . The tile leveling system of  claim 7 , wherein the threaded rod is made of metallic material, and the rotary member is made of plastic material. 
     
     
         9 . The tile leveling system of  claim 1 , wherein the threaded rod and the rotary member are made of plastic material and are formed integrally.
