Abstract
A method of assembling resilient floorboards is disclosed that includes the step of bending an edge of a floorboard during the assembling. The bending reduces the force required for connection of the edge to another edge of a juxtaposed floorboard. The floorboards may be provided with a mechanical locking system for vertical and horizontal locking of two adjacent floorboards.
Claims19
A set of resilient floorboards, each floorboard provided with a mechanical locking system for vertical and horizontal locking to an adjacent floorboard, the mechanical locking system comprising a first device at a first edge, and a second device at a second edge,
- wherein the floorboards each include a core made of a thermoplastic material,
- wherein the first device comprises a downwardly protruding locking element and the second device comprises an upwardly protruding locking element,
- wherein the downwardly protruding locking element is provided with an angled first locking surface configured to cooperate with an angled second locking surface of the upwardly protruding locking element of the adjacent floorboard for locking the first edge vertically and horizontally with the second edge of the adjacent floorboard,
- wherein the first edge and the first device are resiliently bendable with an axis of curvature that is perpendicular to the second edge of the second floorboard, the curvature being convex toward the bottom surface of the floorboards,
- wherein the first device further comprises a locking groove configured to form a tight fit with the upwardly protruding locking element, wherein the angled first locking surface is configured to contact the angled second locking surface of the upwardly protruding locking element, and wherein a surface of the locking groove opposite the angled first locking surface is configured to contact a surface of the upwardly protruding locking element opposite the angled second locking surface,
- wherein the first edge comprises a first top edge and the second edge comprise a second top edge, wherein a surface of the first top edge and a surface of the second top edge are vertical.
