Abstract

Floor coverings having a greige good, an adhesive layer, and a secondary backing material. The greige good has a primary backing component having adjoined first and second portions, and a plurality of fibers. The secondary backing material has an attached portion and a first exposable portion, with the attached portion adhered to the first portion of the primary backing component by contact with the adhesive layer. The second portion of the primary backing component is unattached to the first exposable portion of the secondary backing material, and the first exposable portion defines a portion of the first end edge of the floor covering. The second portion of the primary backing component is selectively moveable relative to the first portion to a position in which at least a portion of the second portion of the primary backing component does not overlie the first exposable portion of the secondary backing material.

First claim

What is claimed is:

1. A floor covering having opposed first and second side edges and opposed first and second end edges extending between and oriented perpendicularly to the first and second side edges, the floor covering having a width corresponding to a distance between the first and second side edges and a length corresponding to a distance between the first and second end edges, the floor covering comprising:
(a) a greige good comprising:
(i) a primary backing component defining a face surface and an opposed back surface and having a first portion and a second portion adjoining the first portion, wherein the first and second portions of the primary backing component extend along respective portions of the length of the floor covering; and
(ii) a plurality of fibers attached to the primary backing component and extending from the face surface of the primary backing component; and

(b) an adhesive layer having a first surface and an opposed second surface and comprising an adhesive composition, wherein the first surface of the adhesive layer is applied to the back surface of the first and second portions of the primary backing component, wherein the portion of the adhesive layer applied to the second portion of the primary backing component and the second portion of the primary backing component cooperate to define a moveable body; and
(c) a secondary backing material having an attached portion and at least a first exposable portion, wherein the attached portion is adhered to the first portion of the primary backing component by contact with the second surface of the adhesive layer underlying the first portion of the primary backing component, wherein the moveable body is unattached to the first exposable portion of the secondary backing, and wherein the first exposable portion defines a portion of the first end edge of the floor covering,
wherein the moveable body is selectively moveable relative to the first portion of the primary backing component to a position in which at least a portion of the second surface of the adhesive layer of the moveable body is vertically spaced from the first exposable portion of the secondary backing material.

2. The floor covering of claim 1 , further comprising a sealing material disposed onto the second surface of the adhesive layer applied to the moveable body, wherein the sealing material is configured to create a barrier between the adhesive layer of the moveable body and the first exposable portion of the secondary backing material.

3. The floor covering of claim 1 , wherein the moveable body is configured for selective pivotal movement relative to the first portion of the primary backing component such that the moveable body is moveable about and between a closed position and an open position, wherein in the closed position, the moveable body overlies the first exposable portion of the secondary backing material and cooperates with the first exposable portion to define the first end edge of the floor covering.

4. The floor covering of claim 3 , wherein the moveable body is configured to pivot about a pivot axis defined at an intersection between the first and second portions of the primary backing component such that the moveable body is moveable between the closed position and the open position, wherein the pivot axis is perpendicular to a longitudinal axis of the floor covering extending from the first end edge to the second end edge, wherein in the open position, the moveable body is folded inwardly toward the first portion of the primary backing component, and wherein the pivot axis is spaced from the first end edge by a selected distance corresponding to a length of the moveable body.

5. The floor covering of claim 1 , wherein each of the primary backing component and the secondary backing component comprises polypropylene, polyethylene terephthalate, polyethylene, or combinations thereof.

6. The floor covering of claim 1 , wherein the adhesive composition comprises a thermoplastic elastomer selected from the group consisting of a polyethylene elastomer, a polypropylene elastomer, and an ethylene methyl acrylate (EMA) elastomer.

7. The floor covering of claim 1 , wherein the secondary backing material further comprises a polymer film, wherein the polymer film is continuous and substantially free of perforations, and wherein the polymer film is substantially impermeable to at least one of fluid or gas.

8. The floor covering of claim 7 , wherein the polymer film is a thermoplastic film or a composite film and comprises polyethylene, polypropylene, polyurethane, polyester, polyvinylchloride, or a combination thereof.

9. The floor covering of claim 7 , wherein the polymer film comprises a polypropylene core.

10. The floor covering of claim 8 , wherein the polymer composite film comprises at least three layers, and wherein each outer layer of the composite film comprises polyethylene.

11. The floor covering of claim 7 , wherein the polymer film is an extruded film, a blown film, a cast film, an engineered film, or combinations thereof.

12. The floor covering of claim 1 , wherein the plurality of fibers are synthetic turf fibers.

13. The floor covering of claim 1 , wherein the primary backing component further comprises a third portion adjoining the first portion of the primary backing component, wherein the first, second, and third portions of the primary backing component extend along respective portions of the length of the floor covering such that the first portion is positioned between the second and third portions relative to the length of the floor covering, wherein the first surface of the adhesive layer is applied to the back surface of the first, second, and third portions of the primary backing component, wherein the portions of the adhesive layer applied to the second and third portions of the primary backing component and the second and third portions of the primary backing component cooperate to define respective first and second moveable bodies, wherein the secondary backing material further comprises a second exposable portion, wherein the second moveable body is unattached to and configured to overlie the second exposable portion of the secondary backing material, wherein the second exposable portion defines a portion of the second end edge of the floor covering, and wherein the second moveable body is selectively moveable relative to the first portion of the primary backing component to a position in which at least a portion of the second surface of the adhesive layer of the second moveable body is vertically spaced from the second exposable portion of the secondary backing material.

14. The floor covering of claim 13 , further comprising a sealing material disposed onto the second surfaces of the adhesive layer applied to the first and second moveable bodies, wherein the sealing material is configured to create a barrier between the adhesive layer of the first and second moveable bodies and the first and second exposable portions of the secondary backing material.

15. The floor covering of claim 13 , wherein the second moveable body is configured for selective pivotal movement relative to the first portion of the primary backing component such that the second moveable body is moveable about and between a closed position and an open position, wherein in the closed position, the second moveable body overlies the second exposable portion of the secondary backing material and cooperates with the second exposable portion to define the second end edge of the floor covering.

16. The floor covering of claim 15 , wherein the second moveable body is configured
