Abstract

A floor panel and a floating floor system include a top surface and a bottom surface. The top surface has a visible decorative pattern and the bottom surface has a recess which extends about the periphery of the bottom surface. The recess has a recess surface. The floor panel includes a joining member with a top surface and a bottom surface. The top surface of the joining member is adhered to the recess surface of the recess. The bottom surface of the joining member and the bottom surface of the floor panel are essentially flush which each other. The use of the joining member does not create any imprints on the top surface of the floor panel.

First claim

What is claimed is:

1. A floor panel apparatus comprising:
a floor panel comprising:
a first end, a second end, a third end, a fourth end, a top surface, a side surface extending downwardly from the top surface to define a periphery of the floor panel, and a bottom surface, the top surface having a visible decorative pattern, the bottom surface of the floor panel having a recess which extends about the periphery of the floor panel, the recess defined by a recess wall and a recess surface, wherein the recess surface extends from the side surface of the floor panel to the recess wall as a continuous planar surface, and the recess surface is parallel to the bottom surface of the floor panel;
a longitudinal axis extending from the first end of the floor panel to the second end of the floor panel;
a transverse axis extending from the third end of the floor panel to the fourth end of the floor panel; and

a joining member coupled to the floor panel by an adhesive positioned between the recess surface of the recess and a top surface of the joining member, the adhesive adhering the top surface of the joining member to the recess surface of the recess, a bottom surface of the joining member and the bottom surface of the floor panel being essentially flush with each other, wherein the joining member protrudes longitudinally beyond the first end of the floor panel in the first longitudinal direction and protrudes transversely beyond the fourth end of the floor panel in a first transverse direction.

2. The floor panel apparatus according to claim 1 wherein the joining member is an L-shaped member.

3. The floor panel apparatus according to claim 1 further comprising a release member adhered to the portion of the joining member that protrudes longitudinally beyond the first end of the floor panel in the first longitudinal direction and transversely beyond the fourth end of the floor panel in a first transverse direction.

4. The floor panel apparatus according to claim 1 wherein the floor panel comprises one or more of a mix layer, a print film comprising the visible decorative pattern, a wear layer and a top coat.

5. The floor panel apparatus according to claim 1 wherein the recess continuously extends about the periphery of the floor panel to form a closed-geometry.

6. The floor panel apparatus according to claim 5 wherein the closed-geometry is a rectangle.

7. The floor panel apparatus according to claim 1 wherein the adhesive covers an entirety of the top surface of the joining member.

8. The floor panel apparatus according to claim 1 wherein the joining member comprises a first portion that extends substantially parallel to the longitudinal axis and second portion that extends substantially parallel to the transverse axis, the first and second portions being integrally formed as single component.

9. The floor panel apparatus according to claim 1 wherein the recess is defined by a recess wall and a recess surface, the recess wall extending from the bottom surface of the floor panel to the recess surface as a continuous planar surface, the recess surface extending from the side surface of the floor panel to the recess wall as a continuous planar surface, wherein the side surface terminates at the top surface and at the recess surface.

10. The floor panel apparatus according to claim 1 wherein the joining member is a film or a tape, and wherein the floor panel is a flexible sheet.

11. A floor panel apparatus comprising:
a floor panel comprising:
a first end, a second end, a third end, a fourth end, a top surface, a side surface extending downwardly from the top surface to define a periphery of the floor panel, and a bottom surface, the top surface having a visible decorative pattern, the bottom surface of the floor panel having a recess which extends about the periphery of the floor panel to the side surface of the floor panel as a substantially rectangular continuous planar surface;
a longitudinal axis extending from the first end of the floor panel to the second end of the floor panel;
a transverse axis extending from the third end of the floor panel to the fourth end of the floor panel; and

a joining member positioned within the recess and coupled to the floor panel by an adhesive, a bottom surface of the joining member and the bottom surface of the floor panel being essentially flush with each other, the joining member comprising:
a first portion that extends substantially parallel to the longitudinal axis, the first portion: (1) protruding transversely beyond the fourth end of the floor panel in a first transverse direction; and (2) protruding longitudinally beyond the first end of the floor panel in a first longitudinal direction; and
the first portion having a first end and a second end, the second end of the first portion being offset from the second end of the floor panel in the first longitudinal direction; and
a second portion that extends substantially parallel to the transverse axis, the second portion protruding longitudinally beyond the first end of the floor panel in the first longitudinal direction, the second portion having a first end that is offset from the third end of the floor panel in the first transverse direction.

12. The floor panel apparatus according to claim 11 wherein the recess is defined by a recess wall and a recess surface, the recess wall extending from the bottom surface of the floor panel to the recess surface as a continuous planar surface, the recess surface extending from the side surface of the floor panel to the recess wall as a continuous planar surface, wherein the side surface terminates at the top surface and at the recess surface, the periphery comprising the first, second, third and fourth ends of the floor panel.

13. The floor panel apparatus according to claim 12 wherein the side surface of the floor panel extends from the top surface of the floor panel to the recess surface as a continuous planar surface, and wherein the periphery of the floor panel defines an outermost boundary of the floor panel.

14. The floor panel apparatus according to claim 12 wherein the adhesive adheres a top surface of the joining member to the recess surface of the recess.

15. The floor panel apparatus according to claim 11 wherein the joining member is an L-shaped member.

16. The floor panel apparatus according to claim 11 further comprising a release member adhered to the portion of the joining member that protrudes longitudinally beyond the first end of the floor panel in the first longitudinal direction and transversely beyond the fourth end of the floor panel in a first transverse direction.

17. The floor panel apparatus according to claim 11 wherein the floor panel comprises one or more of a mix layer, a print film comprising the visible decorative pattern, a wear layer and a top coat.

18. The floor panel apparatus according to claim 11 wherein the adhesive covers an entirety of the top surface of the joining member.

19. The floor panel apparatus according to claim 11 wherein the first and second portions are integrally formed as a single component.
