Abstract

Systems and methods can include scoring a backing material of a luxury vinyl plank (“LVP”) to allow an otherwise rigid plank to flex within a scoring section. The scoring section can include multiple parallel grooves that reach a depth that partially scores the backing material. The LVP can be positioned on a stair tread such that the scoring section wraps around an edge of the tread nose. The LVP can be clamped on top and bottom of the stair tread nose to allow adhesives to take effect. A scoring device can include a blade assembly with multiple blades to create multiple scored grooves in one pass.

Claims (36)

1. A luxury vinyl floorcovering that can be used on flat surfaces or stair treads, comprising:

a rectangular decorative layer for foot traffic; and

a rectangular backing layer comprising a bottommost layer, wherein the backing layer is adhered to the decorative layer, the backing layer including a scoring section of parallel grooves that run parallel to a width of the backing layer and the luxury vinyl floorcovering, wherein the scoring section flexes for bending the decorative and backing layers around a rounded stair nose on a jobsite,

wherein the parallel grooves do not fully penetrate the bottommost layer; and

wherein the parallel grooves are approximately 1/16 inches apart and approximately 1/16 inches deep.

2. The luxury vinyl floorcovering of claim 1 , wherein the scoring section is closer to a first side of the luxury vinyl floorcovering than to a second side and is created at a jobsite by cutting the parallel grooves into the backing layer.

3. The luxury vinyl floorcovering of claim 1 , wherein the luxury vinyl floorcovering is flat prior to bending around a stair nose.

4. The luxury vinyl floorcovering of claim 1 , wherein the parallel grooves have the depth and width.

5. The luxury vinyl floorcovering of claim 1 , wherein the parallel grooves do not fully penetrate the backing layer.

6. The luxury vinyl floorcovering of claim 1 , wherein the backing layer is polyvinyl chloride (“PVC”).

7. The luxury vinyl floorcovering of claim 1 , wherein the luxury vinyl floorcovering is attached to a stair that includes the rounded stair nose by directly applying glue to the stair.

8. The luxury vinyl floorcovering of claim 1 , wherein the scoring section is less than three inches deep when measuring across the parallel grooves.

9. The luxury vinyl floorcovering of claim 1 , further comprising an adhesive for attaching the backing layer to a stair at a jobsite.

10. The luxury vinyl floorcovering of claim 1 , further comprising an installation clamp with an opening that has a thickness selected to match a thickness of a stair tread to which the LVP is being attached.

11. The luxury vinyl floorcovering of claim 1 , wherein the scoring section is closer relative to one side of the luxury vinyl floorcovering than to an opposite side, and has a size and location based on measurements of the stair tread.

12. The luxury vinyl floorcovering of claim 1 , wherein the scoring section is closer relative to one side of the luxury vinyl floorcovering than to an opposite side, and is created with a scoring tool with multiple parallel blades that make at least some of the parallel grooves in a single pass across the backing layer.

13. The luxury vinyl floorcovering of claim 1 , wherein the scoring section is closer relative to one side of the luxury vinyl floorcovering than to an opposite side, and is created using a guide on the backing layer, wherein a scoring instrument is run parallel to the guide.

14. A system for installing luxury vinyl floorcovering, comprising:

a router with multiple parallel blades; and

a luxury vinyl floorcovering that includes:

a rectangular decorative layer for foot traffic; and

a rectangular backing layer with a bottommost layer, the backing layer being adhered to the decorative layer, wherein the router creates a scoring section on the backing layer, the scoring section including parallel grooves that run parallel to a width of the backing layer, wherein the scoring section flexes for bending the decorative and backing layers around a rounded stair nose at a jobsite,

wherein the parallel grooves do not fully penetrate the bottommost layer; and

wherein the parallel grooves are approximately 1/16 inches apart and approximately 1/16 inches deep.

15. The luxury vinyl floorcovering system of claim 14 , wherein the parallel grooves are approximately 1/16 inches apart and approximately 1/16 inches deep.

16. The luxury vinyl floorcovering system of claim 14 , wherein the scoring section is created at the jobsite by cutting the parallel grooves into the backing layer.

17. The luxury vinyl floorcovering system of claim 14 , wherein the LVP plank is flat prior to bending around a stair nose.

18. The luxury vinyl floorcovering system of claim 14 , wherein the router adjusts blade height according to backing layer thickness such that the parallel grooves do not fully penetrate the backing layer.

19. A method for covering one or more stairs with luxury vinyl floorcovering, comprising:

scoring a backing material of a piece of luxury vinyl floorcovering to create parallel scored grooves that partially penetrate the backing material and form a scoring section wherein the parallel scored grooves are oriented perpendicularly to a first side of the piece;

placing the piece of luxury vinyl floorcovering onto a stair tread, wherein the scoring section is wrapped around a nose of the stair tread; and

securing the piece of luxury vinyl floorcovering on a top and a bottom of the stair tread with at least one of glue, staples, and a piece of trim, wherein the scoring is performed by using a scoring device that comprises:

a housing;

a trolley that guides the housing in a straight line;

a blade assembly at least partially within the housing that includes multiple blades positioned on an axle; and

a motor to rotate the axle while the scoring device travels down the trolley.
