Abstract

A device for leveling and aligning tiles and method for leveling and aligning tiles are disclosed. In one embodiment, the leveling device includes a body and two spaced and parallel strip members extending transversely from the body. Each of the spaced and parallel strip members extend to the front and rear of the body. Two opposing lateral open windows are formed in the body. A breakaway section is defined along the body. A wedge device is provided for penetrating one or more of the two opposing lateral open windows and exerting a force on the tiles for leveling them relative to each other.

Claims (39)

1. A tile leveling device comprising:

a shaft having an upper portion and a lower portion;

a base orthogonally coupled to the shaft, the base extending to a front of the shaft and the base extending to a rear of the shaft;

a base to shaft coupling including a frangible breakaway section, the base and the shaft being integral prior to frangible separation, the frangible breakaway section being configured to frangibly separate the shaft from the base upon breaking;

a first notch traversing the base toward the front of the shaft, the first notch being subjacent and proximate to the shaft prior to the frangible separation;

a second notch traversing the base toward the rear of the shaft, the second notch being subjacent and proximate to the shaft prior to the frangible separation;

the first notch and the second notch, in combination, providing an I-shape to the base;

a combination of the first notch and the second notch being configured to provide a majority of tile-to-mortar-to-subfloor contact for the leveling device;

a first spacer integrally extending transversely from the front of the lower portion of the shaft and a second spacer integrally extending transversely from the rear of the lower portion of the shaft, each of the first and second spacers configured to position at least one tile at the front of the shaft and at least one tile at the rear of the shaft a predetermined distance apart; and

a vertical traversing subassembly traversing the upper portion of the shaft, the vertical traversing subassembly configured to exert force against at least one tile by pressing the at least one tile against the base.

2. The tile leveling device as recited in claim 1 , wherein the at least one tile further comprises two tiles.

3. The tile leveling device as recited in claim 1 , wherein the at least one tile further comprises three tiles.

4. The tile leveling device as recited in claim 1 , wherein the at least one tile further comprises four tiles.

5. The tile leveling device as recited in claim 1 , wherein the base further comprises spaced first, second, third, and fourth bars extending transversely from the shaft, the spaced first and second bars extending to the front of the body and the spaced third and fourth bars extending to the rear of the body.

6. The tile leveling device as recited in claim 5 , further comprising a first crossbar located between the spaced first and second bars and a second crossbar located between the spaced third and fourth bars.

7. A tile leveling device comprising:

a shaft having an upper portion and a lower portion;

a base orthogonally coupled to the shaft, the base extending to a front of the shaft and the base extending to a rear of the shaft;

a base to shaft coupling including a frangible breakaway section, the base and the shaft being integral prior to frangible separation, the frangible breakaway section being configured to frangibly separate the shaft from the base upon breaking;

a first notch traversing the base toward the front of the shaft, the first notch being subjacent and proximate to the shaft prior to the frangible separation;

a second notch traversing the base toward the rear of the shaft, the second notch being subjacent and proximate to the shaft prior to the frangible separation;

a combination of the first notch and the second notch being configured to provide a majority of tile-to-mortar-to-subfloor contact for the leveling device;

a first spacer integrally extending transversely from the front of the lower portion of the shaft and a second spacer integrally extending transversely the rear of the lower portion of the shaft, each of the first and second spacers configured to position at least one tile at the front of the shaft and at least one tile at the rear of the shaft a predetermined distance apart; and

a vertical traversing subassembly traversing the upper portion of the shaft, the vertical traversing subassembly configured to exert force against at least one tile by pressing the at least one tile against the base.

8. The tile leveling device as recited in claim 7 , wherein the at least one tile further comprises two tiles.

9. The tile leveling device as recited in claim 8 , wherein the at least one tile further comprises three tiles.

10. The tile leveling device as recited in claim 8 , wherein the at least one tile further comprises four tiles.

11. A tile leveling device comprising:

a shaft having an upper portion and a lower portion;

a base orthogonally coupled to the shaft, the base extending to a front of the shaft and the base extending to a rear of the shaft;

a base to shaft coupling including a frangible breakaway section, the base and the shaft being integral prior to frangible separation, the frangible breakaway section being configured to frangibly separate the shaft from the base upon breaking;

a first notch traversing the base toward the front of the shaft, the first notch being subjacent to the shaft prior to the frangible separation;

a second notch traversing the base toward the rear of the shaft, the second notch being subjacent to the shaft prior to the frangible separation;

a combination of the first notch and the second notch being configured to provide a majority of tile-to-mortar-to-subfloor contact for the leveling device;

a first spacer integrally extending transversely from the front of the lower portion of the shaft and a second spacer integrally extending transversely from the rear of the lower portion of the shaft, each of the first and second spacers configured to position at least one tile at the front of the shaft and at least one tile at the rear of the shaft a predetermined distance apart; and

a vertical traversing subassembly traversing the upper subassembly portion of the shaft, the vertical traversing configured to exert force against at least one tile by pressing the at least one tile against the base.

12. The tile leveling device as recited in claim 11 , wherein the at least one tile further comprises two tiles.

13. The tile leveling device as recited in claim 11 , wherein the at least one tile further comprises three tiles.

14. The tile leveling device as recited in claim 13 , wherein the at least one tile further comprises four tiles.
