Tile levelling device

1. A tile levelling device comprising:

a base portion having an upper surface and an opposing lower surface, one or more generally V-shaped recess being formed in the upper surface;

a stem frangibly connected to the base portion at or near a low point of said one or more recess, the stem including a hole adapted to receive a wedge;

wherein a proximal portion of the stem adjacent to the base portion has a generally V-shaped profile which is more acute than the profile of the generally V-shaped recess.

2. The tile levelling device of claim 1 , wherein the stem is connected to the base portion with a frangible web.

3. The tile levelling device of claim 2 , wherein the frangible web has a generally rectangular cross section.

4. The tile levelling device of claim 2 , wherein an uppermost portion of the frangible web is located below the upper surface of the base portion.

5. The tile levelling device of claim 3 , wherein an upper portion of the stem includes a rounded projection adapted to provide an impact point for separating the stem from the base portion.

6. The tile levelling device of claim 2 , wherein the upper surface of the base portion includes one or more adhesive bonding channels.

7. The levelling device claim 3 , wherein the hole is generally rectangular.

8. The tile levelling device of claim 1 , wherein the profile of the generally V-shaped recess defines an angle of approximately 90 degrees.

9. The tile levelling device of claim 1 , wherein the device is integrally formed by an injection moulding process.

10. The tile levelling device of claim 1 , wherein the one or more generally V-shaped recess comprises two generally V-shaped recesses.

11. The tile levelling device of claim 10 , wherein the stem comprises two stems, and wherein each of the two stems is frangibly connected to the base portion at or near a low point of a corresponding one of the two generally V-shaped recesses.

12. The tile levelling device of claim 11 , further comprising an upper portion, wherein the upper portion comprises a body and the two stems, and wherein the hole is bounded on two sides by the two stems, bounded on one side by the body, and bounded on one side by the base portion.

13. The tile levelling device of claim 10 , wherein one or more channels are formed in the upper surface of the base portion and positioned between the two generally V-shaped recesses.

14. The tile levelling device of claim 13 , wherein the one or more channels are substantially perpendicular to the two generally V-shaped recesses.

15. The tile levelling device of claim 10 , wherein the stem is configured to be tilted relative to the base portion due to the generally V-shaped profile of the stem being more acute than the profile of the generally V-shaped recess.

16. The tile levelling device of claim 2 wherein the stem is pivotable through a range of motion in a clockwise or counter clockwise direction, the range of motion being limited by an abutment of the proximal portion of the stem with a wall of the recess.

17. A method of levelling adjacent edges of two adjacent tiles, the method including the steps of:

placing a base portion of a tile levelling device beneath the adjacent edges, wherein the base portion includes one or more generally V-shaped recess formed in an upper surface thereof;

locating the base portion such that a stem extending away from the base portion passes between a space located between the adjacent edges, wherein a proximal portion of the stem adjacent to the base portion has a generally V-shaped profile which is more acute than the profile of the generally V-shaped recess;

forcing a wedge through a hole formed in the stem to clamp the two adjacent tiles between the upper surface of the base portion and a lower surface of the wedge; and

frangibly separating the stem from the base portion such that the base portion remains completely beneath an underside of each of the two adjacent tiles.
