Definitions

  • the present invention relates to a building panel such as a floor panel, a wall panel, a ceiling panel, a furniture component or the like, which is provided with a mechanical locking system comprising a displaceable tongue.
  • a mechanical locking system comprising a displaceable tongue cooperating with a tongue groove for vertical locking is known and disclosed in, e.g., FR 2 975 716 .
  • the mechanical locking system in FR 2 975 716 has a displaceable tongue comprising an outer element which is pushed by a wedge part of a removable inner part of the tongue into a tongue groove, for vertical locking of adjacent edges of two floorboards.
  • a drawback with this known system is that the locking strength is rather low.
  • a further object of embodiments of the present disclosure is to provide building panels, such as floorboards, wall panels or panels for furniture, provided with a locking system that comprises a tongue that improves the vertical locking of the floorboards.
  • Another object of embodiments of the present disclosure is to provide a more efficient production method, which requires less complicated production equipment.
  • the building panels such as floorboards, are provided with a locking system that comprises a displacement groove at a first edge of a first floorboard and a tongue groove at a second edge of a second floorboard.
  • a tongue is arranged in the displacement groove and is configured to cooperate, in a second position, with the tongue groove for vertical locking of the first edge and the second edge.
  • the tongue comprises, in a first position, an inner element and an outer element.
  • the inner element is removable along the displacement groove, and is configured to cooperate with the outer element to obtain a displacement of the outer element towards the tongue groove and thereby obtain the second position.
  • the inner element and the outer element are preferably configured to vertically overlap each other in the first position to obtain an increased contact surface between a surface of the displacement groove and the outer element of the tongue in the second position.
  • the inner element and the outer element are arranged such that the increased contact surface takes up a moment of force that arises on the tongue when a load is applied on the first or the second floorboard.
  • the inner element in the first position may be arranged above or below the outer element.
  • the inner element in the first position may also be arranged partly above and partly behind the outer element, or may be arranged partly below the outer element and partly behind the outer element.
  • the entire outer element is in the first position preferably arranged within the displacement groove.
  • the first position may be an initial position before a removal of inner element is initiated.
  • Said inner element and said outer element preferably vertically overlap each other when the inner element is displaced in order to remove the inner element from the displacement groove.
  • the inner element is preferably a bar element.
  • An advantage with a bar element may be that the inner element may be displaced forth and back in the case the inner element gut stuck during the removal of the inner element.
  • An innermost surface of the inner element, in the first position, may be arranged within the guiding groove along an inner surface of the outer element.
  • the outer element may be provided with a guiding groove at either an inner and upper edge of the outer element or at an inner and lower edge of the outer element, wherein at least a part of the inner element in the first position is arranged in said guiding groove.
  • the outer element may be provided with a guiding groove at an inner surface of the outer element, between an upper surface and lower surface of the outer element, wherein at least a part of the inner element is arranged in said guiding groove in the first position.
  • the guiding groove facilitates the removal of the inner element by guiding the inner element in a controlled manner and provides a groove without obstructions and with an eligible friction.
  • the guiding groove preferably extends essentially along the whole longitudinal length of the outer element. This embodiment of the outer element provides for a simple production of the outer element for example by plastic profile extrusion and cutting of the profile in the desired length.
  • the inner element preferably comprises a first protruding part configured to cooperate with the guiding groove, to obtain said displacement of the outer element.
  • the first protruding part in the first position is preferably arranged outside of the outer element and/or in a recess of the outer element.
  • the first protruding part may be wedge shaped or of an essentially spherical shape. Such shapes facilitate the displacement of the inner element.
  • the outer element may also be provided with guiding surfaces at the location of the first protruding part in the first position.
  • the first protruding part is preferably elastic, to make it easier to displace the first protruding part over irregularities in the displacement groove.
  • the first protruding part may comprise an elastic material and may be provided with a recess to increase the elasticity.
  • the inner element is preferably provided with a second protruding part, preferably configured such that the second protruding part is easy to grasp by an installer of the floorboards.
  • the second protruding part may also be configured such that the inner element is secured in the correct position.
  • the cross section of the inner element may be L-shaped or rectangular or of an essentially circular shape.
  • the inner element may comprise plastic and may be produced by injection moulding or extrusion.
  • An extruded inner element of plastic may be provided with the first and or the second protruding part by heating and compressing a part of the extruded profile in a press tool.
  • the inner and outer element may be produced in one piece by injection moulding of plastic and connected together by a connection configured to break when the inner element is displaced or when the tongue is inserted into the displacement groove.
  • the building panels may comprise a wood-based core, preferably made of at least one of MDF, HDF, OSB, WPC (Wood Plastic Composite), and particleboard, or of plastic, such as vinyl or PVC.
