Quad spacer for installation of flooring systems

1. A spacer for creating a properly dimensioned gap during the installation of a flooring system, the spacer being a generally rectangular base and having opposed sides, opposed ends, a bottom and a top, the improvement characterized by:

the spacer for creating at least three different sized expansion gaps;

the spacer top comprising first, second and third parts each part being a different height above the bottom of the base and each part extending in the same direction above the bottom of the base;

the distance between each of said first, second and third parts and the bottom of the base thus respectively providing first, second and third projections for three different sized expansion gaps, and

the distance between the opposed ends providing a fourth projection and being a different distance when compared to each of the distances between the three parts of the top and the bottom of the base respectively.

2. A spacer for creating one of at least three different sized gaps during the installation of a flooring system, comprising:

a generally rectangular base having first and second opposed sides, first and second opposed ends, a bottom and a top;

the top of the base having an upper surface and a lower surface with a vertical wall therebetween, the upper and lower surfaces being generally parallel to each other and generally parallel to the bottom of the base;

a projection extending upwardly from the base upper surface in a direction opposite to said base lower surface, the projection including a generally flat surface parallel to the upper surface of the base and having a vertical wall between the projection flat surface and the base upper surface;

a first gap width (W 1 ) defined as the distance of the base between two opposed ends;

a second gap width (W 2 ) defined as the distance between the generally flat surface of the projection and the bottom of the base;

a third gap width (W 3 ) defined as the distance between the upper surface of the top of the base and the bottom of the base;

a fourth gap width (W 4 ) defined as the distance between the lower surface of the top of the base and the bottom of the base;

wherein at least two gap widths differ from each other and

wherein one of said gap widths extends transverse to at least one of said second, third and fourth gap widths.

3. The spacer according to claim 1 or claim 2 wherein each of the distances is non-adjustable.

4. A method of installing a floor using flooring planks, each flooring plank having a plank edge, comprising placing at least one spacer of any preceding claim on a subfloor in an abutting relationship with the plank edge to provide a gap between the plank edge and an adjacent structure.

5. The method according to claim 4 wherein the gap is provided between a plank edge and an adjacent vertical wall.

6. The method according to claim 4 wherein the gap is provided between the plank edges of adjacent planks.

7. The spacer according to any of the preceding claims , wherein the spacer comprises a single moulded body.

8. The spacer according to any of the preceding claims , wherein the spacer comprises a single moulded body comprised of a rigid suitable thermoplastic.

9. The spacer according to any of the preceding claims , wherein the spacer is removable and reusable.

10. A method of installing a flooring system with an expansion gap having a non-adjustable width, comprising selecting a spacer according to any of the preceding claims , inserting the spacer on a subfloor adjacent to a vertical surface, and placing a flooring plank in an abutting relationship to the spacer.

11. The method according to claim 10 wherein the spacer has four different gap width projections.

12. The spacer according to claim 2 wherein no two gap widths are the same.

13. The spacer according to claim 1 and further including an additional projection extending upwardly relative to the base to facilitate use of the spacer.

14. The spacer according to claim 2 and further including an additional projection extending upwardly relative to the base to facilitate use of the spacer.

15. The method of claim 4 wherein the spacer includes an additional projection extending upwardly relative to the base to facilitate placing said at least one spacer into said abutting relationship.

16. The method of claim 13 wherein said additional projection facilitates removal of said spacer.

17. The method of claim 10 wherein the spacer includes an additional projection extending upwardly relative to the base to facilitate inserting said spacer on said subfloor.

18. The method of claim 17 wherein said additional projection facilitates removal of said spacer.
