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, and a method for producing said building panel with said locking system.
  • a mechanical locking system comprising a displaceable and resilient tongue cooperating with a tongue groove for vertical locking is known and disclosed in, e.g., WO2006/043893 .
  • the tongue is a separate part and is made of, e.g., plastic, and positioned in an insertion groove at an edge of a panel. The tongue is pushed into the insertion groove during a vertical assembling of the panels and springs back into the tongue groove of an adjacent panel when the panels have reached a locked position.
  • a locking system for panels comprising a tongue, which is slightly longer than the width of a panel, see, e.g., WO2008/004960 , and cooperates with a tongue groove for vertical locking.
  • the tongue is a separate part and is inserted in a displacement groove.
  • the panels may be assembled by a vertical movement and the tongue is pressed between long edges of two adjacent panels and bent along its length direction.
  • WO2008/116623 discloses a locking system comprising a displaceable tongue which is integrally formed with the body of the panel.
  • a drawback with the known system is that a separate tongue must be produced and special inserting machines are required to position the tongue in the insertion groove with high precision.
  • a further object is to provide a locking system and a method to produce a locking system, which comprises a tongue that may be formed out of the edge of the building panel. Such a system simplifies the production since no loose and additional parts are necessary to produce and to position at the correct position in the locking system.
  • Another object is to provide a more efficient production method, which requires a less complicated production equipment.
  • the locking system may comprise a tongue, at first edge of a first building panel, cooperating with a tongue groove, at a second edge of an adjacent second building panel, for vertical locking of the building panels.
  • the method which is a first aspect of the invention, may comprise the steps of:
  • the forming of the insertion groove and the tongue is preferably made in a production line comprising mechanical cutting devices, such as milling tools.
  • the displacement of the tongue into the insertion groove is preferably made in the same production line.
  • the tongue may be displaced by a device, which in a first step displaces the tongue in a vertical direction and in a second step displaces the tongue in a horizontal direction and into the insertion groove.
  • the parts of the outer shape of the tongue may be formed at an upper part of the first edge, preferably above the insertion groove.
  • the insertion groove may be formed below the upper part of the first edge and the tongue may be displaced downwards and into the insertion groove.
  • the method may furthermore comprise the step of forming a connection part between the tongue and an upper edge of the first edge.
  • the method may comprise the step of forming a connection part by forming a groove between an upper edge of the first edge and outer parts of the tongue.
  • the connection part may have the advantage that the tongue is in fixed position until the tongue is displaced.
  • the method may comprise the step of breaking the connection part by the displacement of the tongue.
  • the connection part may also be cut off, preferably in connection with the displacement of the tongue.
  • the method may comprise the step of forming the tongue groove, at the second edge.
  • An inner groove may be formed throughout the tongue, between the tongue and the first edge of the building panel, in order to obtain a resilient tongue part.
  • the inner groove may extend in the longitudinal direction of the tongue and between a first and a second protruding part of the tongue, at the third and the fourth edge of the building panel respectively.
  • the resilient tongue part may extend from the first to the second protruding part. Before the tongue is displaced into the insertion groove the protruding parts may function as connection parts as described above.
  • the method may comprise the step of forming a sidewall in the insertion groove at a third edge of the first building panel, which is adjacent the first edge, and forming an opening of the insertion groove at a fourth edge at, which is opposite the third edge and adjacent the first edge.
  • the tongue may be displaced to a position in which a pressing part of the tongue protrudes through the opening of the insertion groove. This position has also a displacement of the tongue in a direction along the first edge of the building panel.
  • the tongue may, in a locked position of the first and second edge, be pressed between the sidewall and an edge of an adjacent building panel, such that the tongue bends and a part of the tongue is pushed into the tongue groove.
  • the tongue may essentially have the same length as the length of the first edge.
  • the method may comprise the step of forming a locking element at the first edge and a locking groove at the second edge or a locking element at the second edge and a locking groove at the first edge, wherein said locking element and locking groove are configured to cooperate for locking of the first and the second edge in the horizontal direction.
  • the production steps above may be performed in any order.
  • the building panel may also be positioned upside down in the production line.
  • the locking system is preferably formed by mechanical cutting, such as milling, drilling, cutting by knife and/or sawing, of the edges of the building panels.
  • a second aspect of the invention is building panels, which preferably are produced according to an embodiment of the first aspect, provided with a mechanical locking system.
  • the locking system may comprise a tongue, at first edge of a first building panel, cooperating with a tongue groove, at a second edge of an adjacent second building panel, for vertical locking of the building panels.
  • the tongue is preferably produced of material of the first edge.
  • the tongue may be at least partly positioned in an insertion groove at the first edge.
  • the tongue may be displaceable in the insertion groove to enable a vertical assembling of the first and the second edge.
  • An embodiment may have a resilient part between the displaceable tongue and a bottom wall of the insertion groove.
  • the resilient part makes it possible to push the displaceable tongue into insertion groove, by an edge of the second edge, during a vertical assembling of the first and the second edge.
  • the tongue springs back and into the tongue groove when the first and the second building panel have reached a locked position.
  • the embodiment with the resilient part is particularly useful for building panels with edges comprising a rigid material, such as solid wood.
  • a resilient part may not be necessary for building panels with edges comprising a resilient material, such as plastic and vinyl. For such building panels it may be possible to configure a tongue, which is compressible enough to be pushed into insertion groove during the vertical assembling.
  • the displaceable tongue may, in another embodiment, be configured such that when pressed between a sidewall in the insertion groove and an edge of an adjacent third building panel the tongue bends and a part of the tongue is pushed into the tongue groove.
  • This solution is particularly useful for building panels with edges comprising wood, such as HDF or MDF.
  • the sidewall may be arranged in the insertion groove at a third edge of the first building panel, which is adjacent the first edge and the insertion groove may have an opening at a fourth edge, which is opposite the third edge and adjacent the first edge.
  • the displaceable tongue may be positioned such that a press part of the displaceable tongue protrudes through the opening. Such a position improves the possibilities to apply a force on the press part.
  • Another embodiment comprises a fixed tongue, which preferably is arranged firmly in the insertion groove.
  • the fixed tongue comprises a protruding part, which protrudes outside the upper edge of the first edge and cooperates with the tongue groove for the vertical locking.
  • a first and a second edge provided with a locking system comprising the fixed tongue may be assembled by an angular movement.
  • This embodiment is particularly advantageous for thin building panels, preferably with a thickness in the range of about 3-7 mm or more preferably in the range of about 4-6 mm.
  • a reason is that it's easier to produce a locking system, which comprises a displaceable tongue, at the edge of a thicker building panel than at the edge of a thinner building panel.
  • the tools for forming a locking system with a displaceable tongue require more space and material than the tools for forming a locking system with a fixed tongue.
  • This embodiment is particularly useful for plastic and vinyl tiles, which normally have a thin thickness.
  • Embodiments of the locking system and the building panels in the above first and the second aspect may comprise the features described below.
  • a contact surface of the tongue groove may cooperate, for the vertical locking, with a contact surface of the tongue.
  • the contact surface may be positioned such that when the displaceable tongue springs back and into the tongue groove, during a vertical assembling of the building panels, the tongue is prevented to reach its original position.
  • the contact surface of the tongue asserts a force against the contact surface of the tongue groove in order to avoid a play between the panels.
  • the contact surface may be positioned such that when the displaceable tongue is pushed into the tongue groove the contact surface of the tongue asserts a force against the contact surface of the tongue groove in order to avoid a play between the panels.
  • the locking system may comprise a locking element, preferably arranged on a locking strip, at the first edge of the first panel and a locking groove at the second edge of the second panel or locking groove at the first edge of the first panel and a locking element at the second edge of the second panel. Said locking element and locking groove cooperate, for locking the panels horizontally.
  • the first and the second building panel are preferably essentially equal, thus an edge opposite said first edge of the first panel is provided with the same parts of the locking system as said second edge of the second panel.
  • the panels may be square-shaped and the edges between said first and said opposite edge are preferably provided with a locking system, which enables assembling to an adjacent panel by an angling movement.
  • the insertion groove may be filled with a resilient material or part, such as plastic or rubber, to improve the resilient properties of the displaceable part and/or to make the locking system stronger.
  • the building panel may be a floor panel, a wall panel, a ceiling panel, a furniture component or the like.
  • the core of the building panels may be a wood-based core, preferably made of MDF, HDF, OSB, WPC, or particleboard or of plastic, e.g., vinyl or PVC.
  • the edge of the panels, of which the locking system may be made may comprise the core material.
  • a known locking system for building panels which comprises a displaceable and resilient tongue 30, at a first edge 4a of a first panel 1, cooperating with a tongue groove 20, at a second edge 4b of a second panel 1', for vertical locking of the first and a second edge 4a, 4b, is shown in FIG. 1 .
  • the tongue 30 is a separate part and is made of, e.g., plastic, and is arranged in an insertion groove at the first edge 4a.
