Claims14
A locking system for mechanical joining of a plurality of floorboards, wherein an immediately juxtaposed upper part of each of two neighboring joint edge portions of two joined floorboards together define a vertical plane which is perpendicular to a principal plane of the two joined floorboards, said locking system comprising:
- a locking groove formed in a first neighboring joint edge portion of a first floorboard and extending parallel to the first neighboring joint edge portion;
- and
- a strip integrated with a second neighboring joint edge portion of a second floorboard, the strip including a projecting portion which, at a distance from the vertical plane, supports a locking element coacting with the locking groove, the projecting portion located completely outside the vertical plane as seen from a side of the second neighboring joint edge portion,
- wherein the strip is formed by machining a sheet-shaped material, and
- wherein the strip is joined with a core of the second floorboard using a mechanical snap joint which joins the strip with the second floorboard in a horizontal direction and a vertical direction by a relative displacement of the strip and the second neighboring joint edge portion of the second floorboard towards each other, and
- wherein the locking system joins the two neighboring joint edge portions in the horizontal direction perpendicular to the vertical plane and parallel with the principal plane.
A locking system for mechanical joining of a plurality of floorboards, wherein an immediately juxtaposed upper part of each of two neighboring joint edge portions of two joined floorboards together define a vertical plane which is perpendicular to a principal plane of the two joined floorboards, said locking system comprising:
- a locking groove formed in a first neighboring joint edge portion of a first floorboard and extending parallel to the first neighboring joint edge portion;
- and
- a strip attached to a second neighboring joint edge portion of a second floorboard, the strip including a projecting portion which, at a distance from the vertical plane, supports a locking element coacting with the locking groove, the projecting portion located completely outside the vertical plane as seen from a side of the second neighboring joint edge portion;
- and
- the strip is attached to the core of the second floorboard with a mechanical snap joint which locks the strip to the second floorboard in a horizontal direction and in a vertical direction by a relative displacement of the strip and the second neighboring joint edge portion of the second floorboard towards each other;
- and
- the locking system joins the two neighboring joint edge portions in the horizontal direction perpendicular to the vertical plane and parallel with the principal plane.
A strip blank for a plurality of floorboards adapted to be locked together with a mechanical locking system in a both a vertical and a horizontal direction, the strip blank comprising at least two strips, each of the strips including at least a portion of the mechanical locking system which locks two adjoining floorboards horizontally.
A strip for a floorboard adapted to be locked to a similar floorboard with a mechanical locking system in a both a vertical and a horizontal direction, the strip comprising:
- a tongue at one end thereof for mechanically joining the strip to a strip groove in a first floorboard;
- a locking element at a second end thereof for mechanically locking the first floorboard to a second floorboard;
- wherein the strip is made from wood fibers.
A method of providing a plurality of rectangular floorboards, each floorboard having a machined joint portion, with a mechanical locking system which locks the floorboard horizontally and vertically on at least two opposite side edges to an adjoining floorboard, said locking system comprising:
- at least one strip, wherein the strip is made by machining of a sheet-shaped material, the strip is joined with the machined joint portion mechanically in a horizontal direction parallel to a principal plane of the floorboard and in a vertical direction perpendicular to the principal plane, and wherein the mechanical joining of the strip with the floorboard takes place by snapping-in relative to the joint edge.
A method of providing a plurality of rectangular floorboards, each floorboard having a machined joint portion, with a mechanical locking system which locks the floorboard horizontally and vertically on at least two opposite side edges to an adjoining floorboard, said locking system comprising:
- at least one strip locked to the machined joint portion mechanically in a horizontal direction parallel to a principal plane of the floorboard and in a vertical direction perpendicular to the principal plane, and wherein the mechanical locking of the strip with the floorboard includes a flexible portion that is bendable to enable snapping-in relative to the joint edge.
