Abstract
Flooring material including sheet-shaped floor elements with a mainly square or rectangular shape. The floor elements are provided with edges, a lower side and an upper decorative layer. The floor elements are intended to be joined by means of joining members. The floor elements are provided with male joining members on a first edge while a second edge of the floor elements are provided with a female joining member. The male joining member is provided with a tongue and a lower side groove while the female joining member is provided with a groove and a cheek, the cheek being provided with a lip. The floor elements are provided with a male vertical assembly joining member on a third edge while a fourth, opposite, edge is provided with female vertical assembly joining member.
Claims20
A system of surface elements forming a surface comprising:
- a first surface element comprising:
- an upper surface;
- a lower surface;
- a first edge and a second edge, opposite said first edge, joining said upper surface to said lower surface;
- and
- a third edge and a fourth edge, opposite said third edge, joining said upper surface to said lower surface;
- wherein said third edge comprises a separate locking part positioned in a cavity, said separate locking part being formed from at least one member selected from the group consisting of a thermoplastic, a thermosetting resin, and a metal;
- a second surface element, comprising an edge sized and shaped to join with said first edge of said first surface element through relative rotational movement, wherein said first edge of said first surface element and said edge of said second surface element lock said first surface element to said second surface element to limit relative vertical movement;
- and
- a third surface element, comprising an edge sized and shaped to join with said third edge of said first surface element through relative vertical movement, wherein said third edge of said first surface element and said edge of said third surface element lock said first surface element to said third surface element to limit relative vertical movement.
A method of forming a surface comprising:
- providing a first surface element comprising:
- an upper surface;
- a lower surface;
- a first edge and a second edge, opposite said first edge, joining said upper surface to said lower surface;
- and
- a third edge and a fourth edge, opposite said third edge, joining said upper surface to said lower surface;
- providing a second surface element, comprising an edge sized and shaped to join with said first edge of said first surface element through relative rotational movement;
- joining said first edge of said first surface element to said edge of said second surface element through relative rotational movement;
- providing a third surface element, comprising an edge sized and shaped to join with said third edge of said first surface element through relative vertical movement;
- positioning a separate locking part in a cavity formed in the third edge, said separate locking part being formed from at least one member selected from the group consisting of a thermoplastic, a thermosetting resin, and a metal;
- and
- joining said third edge of said first surface element to said edge of said third surface element through relative vertical movement, wherein said separate locking part locks said first surface element to said third surface element to limit relative vertical movement.
A system of surface elements forming a surface comprising:
- a first surface element comprising:
- an upper surface;
- a lower surface;
- a first edge and a second edge, opposite said first edge, joining said upper surface to said lower surface;
- a third edge and a fourth edge, opposite said third edge, joining said upper surface to said lower surface, said third edge comprising a first locking surface;
- and
- a second surface element, comprising an edge sized and shaped to join with said first edge of said first surface element through relative rotational movement, wherein said first edge of said first surface element and said edge of said second surface element lock said first surface element to said second surface element to limit relative vertical movement;
- and
- a third surface element, comprising a second locking surface sized and shaped to join with said first locking surface of said third edge of said first surface element through relative vertical movement, wherein said first locking surface and said second locking surface lock said first surface element to said third surface element to limit relative vertical movement.
A method of forming a surface comprising:
- providing a first surface element comprising:
- an upper surface;
- a lower surface;
- a first edge and a second edge, opposite said first edge, joining said upper surface to said lower surface;
- a third edge and a fourth edge, opposite said third edge, joining said upper surface to said lower surface, said third edge comprising a first locking surface;
- and
- providing a second surface element, comprising an edge sized and shaped to join with said first edge of said first surface element through relative rotational movement;
- joining said first edge of said first surface element to said edge of said second surface element through relative rotational movement;
- providing a third surface element, comprising a second locking surface sized and shaped to join with said first locking surface of said third edge of said first surface element through relative vertical movement;
- joining said third edge of said first surface element to said edge of said third surface element through relative vertical movement, wherein said first locking surface and said third locking surface lock said first surface element to said third surface element to limit relative vertical movement.
