Abstract

A tile aligning and lippage tuning system that uses an under tile base interstitial strap, which is connected to said under tile base, a shim shell cap configured to slip over the connecting tab. A bottom tile mating shim and a top shim.

Claims (40)

1. A tile aligning and leveling system comprising:

a beneath tile base;

a top shim;

a bottom tile mating shim;

an interstitial strap comprising:

a top shim mating protuberance with top shim mating protuberance teeth;

said bottom tile mating shim disposed adjacent said interstitial strap;

said bottom tile mating shim having a channel therein along a top ramp side; and

said top shim disposed in and configured to slide within said channel.

2. The system of claim 1 further comprising a shell disposed over a portion of said top shim and said bottom tile mating shim.

3. The system of claim 2 wherein said shell has a plurality of slots therein for receiving therethrough a first top shim post.

4. The system of claim 3 further comprising a second top shim post for being received in said plurality of slots.

5. The system of claim 4 wherein said top shim has a handle end which is configured to remain separated from said bottom tile mating shim and allow use as a handle.

6. A lippage control system comprising:

a member for cooperating with a back side of a plurality of adjacent tiles;

an elongated interstitial member extending away from said back side and beyond an opposing front side of said plurality of tiles;

a first wedge means for providing a variably positionable inclined ramp;

a second wedge means configured for sliding up said inclined ramp;

said second wedge means comprising a top second wedge rough surface and a bottom second wedge smooth surface;

a pair of opposing posts disposed centrally along an longitudinal axis of said elongated interstitial member; and

said pair of opposing posts configured for frictionally coupling with said rough surface.

7. The system of claim 6 further comprising a shell having opposing and separate sides each having a post receiving groove therein for guiding one of said pair of opposing posts as said second wedge is slid across said inclined ramp.

8. The system of claim 7 wherein said shell has a floor which is configured to contact said front side of said plurality of tiles and further having a first central hole therein which is sized and configured to allow said shell to be place over a top end of said elongated interstitial member and further configured to allow said pair of opposing posts to be located within said shell.

9. The system of claim 8 wherein said shell having a top region between said opposing and separate sides where said top region has a second central hole therein which is sized and configured to allow said shell to further down said elongated interstitial member and further configured to allow said pair of opposing posts to be located at least partially above said top region of said shell.

10. The system of claim 9 wherein said first wedge means has a longitudinal axis and a skew slot extending from a thin end of said first wedge means toward a thick end of said first wedge means, where said skewed slot is configured for allowing said elongated interstitial member to slide into said skewed slot.

11. The system of claim 10 wherein said first wedge means has a wedge central hole therein which is sized and configured to allow said shell, with said first wedge means fully inserted therein, to be place over a top end of said elongated interstitial member and further configured to allow said pair of opposing posts to be located within said shell.

12. The system of claim 11 wherein said first central hole and said wedge central hole are in registration so as to facilitate vertically moving said shell along said elongated interstitial member.

13. A lippage reducing system comprising:

a member configured to be located between a plurality of adjacent tiles and a back plane;

a strap extending from said member between said plurality of adjacent tiles and away from said back plane;

a first shim configured to engage a first surface of said plurality of adjacent tiles and to receive said strap through a void in said first shim; and

a second shim disposed adjacent to said first shim and configured to slide within a channel in said first shim.

14. The system of claim 13 wherein said strap comprises a central protuberance for mating with an outer surface of said second shim.

15. The system of claim 14 further comprising a ridge disposed on said central protuberance for engaging with surface features on said outer surface of said second shim.

16. The system of claim 15 wherein said member is disposed beneath said plurality of adjacent tiles, said first shim is a bottom shim disposed on top of said plurality of adjacent tiles and said second shim is a top shim disposed above said bottom shim.

17. The system of claim 15 further comprising a plurality of ridges disposed on said central protuberance.

18. The system of claim 13 further comprising a shell disposed around a central portion of said first shim and a central portion of said second shim, where said shell has a first groove therein for receiving a first protuberance coupled to said second shim.

19. The system of claim 18 wherein said shell has a first open end for receiving therein said first shim and an opposing end second open end for receiving therein said second shim, where the direction of insertion of said first shim into said shell is substantially opposite to a direction of insertion of said second shim.

20. The system of claim 19 wherein said second shim has a handle end which is configured to remain separated from said first shim and allow use as a handle.

21. The system of claim 20 wherein said shell is not required for operation of said system and said shell provides guidance to facilitate use of the system with a lower level of experience.
