Definitions

  • the present invention relates to a floorboard with a decorative joint portion comprising a U or V-shaped groove 5 and a flooring with such floorboards.
  • the invention concerns a laminate floorboard comprising a mechanical locking system, formed at least at two opposite 10 edges and a decorative joint portion comprising an U " or V- shaped groove only at one of two opposite edges of the floorboard.
  • a mechanical locking system formed at least at two opposite 10 edges
  • a decorative joint portion comprising an U " or V- shaped groove only at one of two opposite edges of the floorboard.
  • a flooring is known with floorboards that is provided with a decorative joint portion, in the form of a bevel at both adjacent joined edges of the floorboards, for example
  • WO 03/078761 Another embodiment described in WO 03/078761 is a flooring comprising floorboards that is provided with a decorative joint portion, in the form of a lower flat portion only at one of two adjacent joined edges of the floorboards.
  • the present invention aims a floorboard and flooring with a decorative joint portion, in particular a laminate floorboard, which provides for new embodiments according to different aspects offering respective advantages.
  • Flooring and floorboards with a decorative joint portion known up to now have several disadvantages.
  • the bevelled joint edge and the joint edge with a lower flat portion both have the disadvantage that they collect moisture and dust., which penetrates into the joint down to the moisture sensitive core.
  • the dust creates a gap in the joint when, the panels move, e.g. due to humidity changes.
  • the floorboard with the decorative joint portion according to the invention results in a more resilient edge, which make it possible to provide a tighter joint, and prevent dust and moisture to enter into the joint .
  • the invention provides for a laminate floorboard comprising a front face a rear face, a surface layer of resin-impregnated sheets, a wood- based core and a decorative joint portion comprising a U or V-shaped groove. If the joint edge is provided with a cut under the groove, forming a clearance when the edge of the floorboard is joined to an adjacent edge of another adjacent floorboard, the edges become more resilient and tighter. A deeper grove also makes the joint more resilient .
  • Laminate flooring usually consists of a core of a 6-3 mm fibreboard, a 0.2-0.8 mm thick upper decorative surface layer of laminate, preferably comprising sheet material impregnated with thermosetting resins and a 0.1-0.6 mm thick lower balancing layer of laminate, plastic, paper or like material.
  • the surface layer provides appearance and durability to "the floorboards, and preferably contains at least one layer imprinted with a pattern, for example a wood pattern printed on a paper layer.
  • the core provides stability, and the balancing layer keeps the board plane when the relative humidity (RH) varies during the year.
  • the floorboards are generally laid floating, i.e. without gluing, on an existing subfloor.
  • a first advantage consists in that there are no dust or moisture collecting lower parts at the edge closet to the joint.
  • a second advantage is that the U or V-shaped groove makes a joint gap less visible.
  • a third advantage is that the joint with the U or V-shaped groove looks like a traditional joint with bevels, but is cheaper to manufacture since only one of the two adjacent joined edges is worked.
  • a fourth advantage is that the groove, due to the upwardly directed ribbon closest to the joint, and the cut make the edge more resilient, which makes- the joint tighter and prevents dust and moisture to enter into the joint .
  • a mechanical locking system is formed at least at two opposite edges of the floorboard, which facilitates the joining of a similar floorboard.
  • Mechanical locking system are for example known from WO 94/26999, and another locking system, comprising a flexible tongue, especially advantageous at the short sides of rectangular floor boards, is descibed in PCT/SE2005/001586, owner
  • only one of two opposite edges of the floorboard is provided with the groove.
  • a rectangular floorboard is preferably provided with the groove at only- one long edge. It is also possible to provide only one of the long and only one of the short edges .
  • Other shapes of the floorboards are also possible, e.g. a floorboard with 3, 5, 6, 7 and B edges.
  • the wood based core is made of MDF or HDf or a particleboard and the groove extends down to the coxe, which optionally is coloured.
  • the groove is according to another embodiment treated with oil or varnish or filled with a filling material.
  • the invention provides for a floorboard comprising a solid wood body, a front face a rear face, a decorative joint portion comprising a U or V-shaped groove.

  • the floorboard is treated with oil or varnish and/or the groove is filled with a filler.
  • the floorboard provided with the decorative joint portion comprising a U or V-shaped groove is further provided with an horizontally protruding part configured such that it overlaps an adjacent edge of an adjacent similar floorboard when the floorboard is joined to the similar adjacent floorboard.
  • the cut under the groove and above the connecting means is for some applications not necessary since the protruding part prevents dust and moisture to penetrate in to the joint.
  • the " joint still looks like a traditional joint with bevels, but is cheaper to manufacture .
