Definitions

  • Panel and method for manufacturing such a panel Panel and method for manufacturing such a panel.
  • the present invention relates to a panel and to a method for manufacturing such a panel.
  • the invention relates to a panel which is rectangular and has long and short edges.
  • the panel comprises a coupling part on each edge which makes it possible to couple the panel to another similar panel.
  • Such panels are known, for example from WO 97/47843.
  • the coupling part is configured at the one long edge to cooperate with the coupling part at the other long edge of another similar panel.
  • the coupling part at the one short edge is configured to cooperate with the coupling part at the other short edge of another similar panel.
  • the cooperating coupling parts form an interlocking tongue and groove connection, both at the long and at the short edges.
  • This is a tongue and groove connection which does not only produce a vertical, but also a horizontal interlocking between the coupled edges.
  • the vertical interlocking is produced by the cooperation between the tongue and the groove.
  • the horizontal interlocking results from an interlocking lip engaging with a downwardly directed interlocking groove.
  • the panels from WO 97/47843 are usually arranged in rows according to a standard pattern. In this case, the panels are installed with a short edge abutting a short edge and a long edge abutting a long edge.
  • Similar panels are also known which allow for more advanced laying patterns.
  • the panels are often installed with a short edge abutting a long edge.
  • This is the case, for example, with herringbone patterns.
  • Such herringbone patterns may be produced using the panels described in WO 03/089736 and WO 2004/063491.
  • a general problem is the fact that two different types of these panels are required in order to achieve the herringbone pattern.
  • the one type of panels is the mirror image of the other type of panels. This not only makes installation of the panels more difficult, as the correct type of panel has to be selected as the next panel to be installed, but it also makes the manufacturing process relatively complicated because two types of panels have to be manufactured.
  • WO 2011/153916 and WO 2015/155312 try to offer a solution to these problems. They propose to construct the coupling part on each edge of the panel to be similar. This offers the advantage that only one type of panel is required in order to produce herringbone patterns. Every coupling part comprises an interlocking lip which is interrupted repeatedly and an interlocking groove which is present at the location of the interruptions in the interlocking lip. With coupled panels, the interlocking lip of the one panel engages with the interlocking groove of the other panel and vice versa. Thus, both a vertical and a horizontal interlocking are produced between the coupled panels. However, the resulting interlocking is not optimal.
  • WO 2005/098163 also describes panels which only require one type in order to produce herringbone patterns.
  • the coupling parts In the coupled position, the coupling parts form an interlocking tongue and groove connection on the long edges.
  • the coupling parts on the short edges are of identical design and are configured to cooperate with each of the coupling parts on the long edges.

Abstract

La présente invention concerne un panneau qui est rectangulaire et présente des bords longs (2-3) et courts (4-5), dans lequel, sur chaque bord long (2-3) et sur chaque bord court (4-5), le panneau (1) comprend une partie d'accouplement (7-8-9-10) qui permet au panneau (1) d'être accouplé à un autre panneau similaire (1) par exemple, selon un motif de chevrons. Les parties d'accouplement au niveau d'un bord long sont partiellement absentes le long d'une partie de sorte que, dans cette partie, l'un des bords courts peut être accouplé au bord long.
