Floorboards, flooring systems and method for manufacturing and installation thereof
Floorboards with a format corresponding to a traditional parquet block for laying of mechanically joined floating flooring. Rectangular floorboards include a surface layer and a core with two long sides and two short sides, for making a floating flooring, which floorboards are mechanically lockable and which along their four sides have pairs of opposing connectors for locking similar, adjoining floorboards to each other both vertically and horizontally wherein the long sides have a length not exceeding 80 cm and the short sides have a width not exceeding 10 cm.
1. A flooring, which comprises rectangular floor-boards for providing a patterned floating flooring, said floorboards comprising:
first and second opposing long edges, and first and second connectors extend along the long edges for locking together one floorboard with a second floorboard,
such that upper edge portions of said one floorboard and said second floorboard, in a joined state, together define a vertical plane,
whereby said first connectors comprise an upwardly projecting locking element on one of the long edges cooperating with a locking groove on the other of the long edges of the second floorboard for locking together said floorboard and said second floorboard in a horizontal plane, perpendicular to said vertical plane, and
whereby said second connectors comprise a tongue and a groove for locking together said floorboard and said second floorboard in a vertical direction, perpendicular to a main plane of said floorboards, wherein
the floorboard further includes first and second opposing short edges, the short edges of said floorboards having a length not exceeding 10 cm, and
the short edges having a locking system comprising a locking element for horizontally locking of said floorboards to another floorboard, and wherein one of the first and second short edges does not have any portion thereof extending past the vertical plane so as to enable the short edges to be joined by vertical folding.
2. The flooring as claimed in claim 1 , wherein the vertical extent of the locking element is 0.1 times the floor thickness and the horizontal extent of the locking element is 0.3 times the floor thickness.
3. The flooring as claimed in claim 1 , wherein said connectors are adapted for locking together said one floorboard and said second floorboard at least by means of inward angling, such that when the long edge of the second floorboard is pressed against an upper part of the long edge of the one floorboard and is then angled down, the locking element can enter the locking groove.
4. The flooring as claimed in claim 3 , wherein said locking system at the short edge are adapted for locking together said one floorboard and said second floorboard by means of inward angling and displacement along the short edge.
5. The flooring as claimed in claim 1 , wherein said connectors are adapted for releasing said one floorboard and said second floorboard by means of upward angling, away from a sub-floor.
6. The flooring as claimed in claim 1 , wherein said second floorboard is substantially identical with said one floorboard.
7. The flooring as claimed in claim 1 , wherein said one floorboard has a surface layer comprising a thermosetting resin.
8. A rectangular floorboard for providing a patterned floating flooring in accordance with claim 1 .
9. The flooring as claimed in claim 1 , wherein the short edge locking element has a vertical extent and a horizontal extent that fits within a locking groove, and the combined vertical and horizontal extent is adapted to withstand a tensile load of about 100 kg or more.
10. A flooring, which comprises rectangular floor-boards for providing a patterned floating flooring, said floorboards being provided,
along opposing long edges, with integrated first and second connectors for locking together one floorboard with a second floorboard,
such that upper edge portions of said one floorboard and said second floorboard, in a joined state, together define a vertical plane,
whereby said first connectors comprise an upwardly projecting locking element on one long side cooperating with a locking groove on the other long side of the second floorboard for locking together said floorboard and said second floorboard in a horizontal plane, perpendicular to said vertical plane, and
whereby said second connectors comprise a tongue and a groove for locking together said one floorboard and said second floorboard in a vertical direction, perpendicular to a main plane of said floorboards,
with first and second opposing short edges having a locking system comprising a locking element for horizontally locking of said one floorboard to another floorboard and wherein one of the first and second short edges does not have any portion thereof extending past the vertical plane so as to enable the short edges to be joined by vertical folding,
the short edge locking element has a vertical extent and a horizontal extent that fits within the locking groove, and the vertical extent is 0.1 times the floor thickness and the horizontal extent is 0.3 times the floor thickness.
11. The flooring as claimed in claim 1 , wherein the long edges of said floorboards have a length not exceeding 80 cm.
12. The flooring as claimed in claim 1 , wherein the short edge locking system only locks horizontally, and a vertical and a horizontal extent of the short edge locking element is adapted to withstand a tensile load of about 100 kg or more without vertical displacement of the short edge.
13. The flooring as claimed in claim 10 , wherein the short edge locking element is adapted to withstand a tensile load of about 100 kg or more.
14. A flooring, which comprises rectangular floorboards for providing a patterned floating flooring, said comprising:
first and second opposing long edges, and first and second connectors extend along the long edges for locking together one floorboard with a second floorboard,
such that upper edge portions of said floorboard and said second floorboard, in a joined state, together define a vertical plane,
whereby said first connectors comprise an upwardly projecting locking element on one of the long edges cooperating with a locking groove on the other of the long edges of the second floorboard for locking together said floorboard and said second floorboard in a horizontal plane, perpendicular to said vertical plane, and
whereby said second connectors comprise a tongue and a groove for locking together said floorboard and said second floorboard in a vertical direction, perpendicular to a main plane of said floorboards, wherein
the floorboard further includes first and second opposing short edges, the short edges of said floorboards having a length not exceeding 10 cm, and the short edges do not include a locking system.
15. The flooring as claimed in claim 14 , wherein the long edges of said floorboards have a length not exceeding 80 cm.
