Definitions

  • the disclosure generally relates to the field of mechanical locking systems for floor panels and building panels.
  • the disclosure shows floorboards, locking systems, installation methods and production methods.
  • the present invention is particularly suitable for use in floating floors, which are formed of floor panels which are joined mechanically with a locking system integrated with the floor panel, i.e. mounted at the factory, are made up of one or more upper layers of veneer, decorative laminate powder based surfaces or decorative plastic material, an intermediate core of wood-fibre-based material or plastic material and preferably a lower balancing layer on the rear side of the core.
  • the long and short edges are mainly used to simplify the description of the invention.
  • the panels may be square.
  • the invention is preferably used on the short edges. It should be emphasised that the invention may be used in any floor panel and it may be combined with all types of known locking system formed on the long edges, where the floor panels are intended to be joined using a mechanical locking system connecting the panels in the horizontal and vertical directions on at least two adjacent sides.
  • the invention may also be applicable to, for instance, solid wooden floors, parquet floors with a core of wood or wood-fibre-based material and a surface of wood or wood veneer and the like, floors with a printed and preferably also varnished surface, floors with a surface layer of plastic or cork, linoleum, rubber. Even floors with hard surfaces such as stone, tile and similar materials are included and floorings with soft wear layer, for instance needle felt glued to a board.
  • the invention may also be used for joining building panels which preferably contain a board material for instance wall panels, ceilings, furniture components and similar.
  • Laminate flooring usually comprises a core of a 6-12 mm fibre board, a 0.2-0.8 mm thick upper decorative surface layer of laminate and a 0.1-0.6 mm thick lower balancing layer of laminate, plastic, paper or like material.
  • a laminate surface comprises of melamine-impregnated paper.
  • the most common core material is fibreboard with high density and good stability usually called HDF - High Density Fibreboard. Sometimes also MDF - Medium Density Fibreboard - is used as core.
  • the visible surface of the installed floor panel is called “front side”, while the opposite side of the floor panel, facing the sub floor, is called “rear side”.
  • the edge between the front and rear side is called “joint edge”.
  • horizontal plane is meant a plane, which extends parallel to the outer part of the surface layer.
  • Immediately juxtaposed upper parts of two adjacent joint edges of two joined floor panels together define a “vertical plane” perpendicular to the horizontal plane.
  • vertical locking is meant locking parallel to the vertical plane in D1 direction.
  • horizontal locking is meant locking parallel to the horizontal plane in D2 direction.
  • up is meant towards the front side, by “down” towards the rear side, by “inwardly” mainly horizontally towards an inner and centre part of the panel and by “outwardly” mainly horizontally away from the centre part of the panel.
  • locking systems co acting connecting elements, which connect the floor panels vertically and/or horizontally.
  • the long edges are installed by angling.
  • the panel is than displaced in locked position along the long side.
  • the short edges are locked by horizontal snapping.
  • the vertical connection is generally a tongue and a groove.
  • a strip with a locking element is bent and when the edges are in contact, the strip springs back and a locking element enters a locking groove and locks the panels horizontally.
  • Such a snap connection is complicated since a hammer and a tapping block may need to be used to overcome the friction between the long edges and to bend the strip during the snapping action.
  • Similar locking systems may also be produced with a rigid strip and they are connected with an angling-angling method where both short and long edges are angled into a locked position.
  • Figure 1a, 1b show a flexible tongue 30 with a flexible snap tab extending from the edge.
  • Figure 1c, 1d show a displaceable tongue with an inner flexible part that is bendable horizontally in a cross section of the tongue or along the joint.
  • Such systems are referred to as vertical snap systems and they provide an automatica locking during the folding action.
  • the locking system may also be locked with a side push action such that a displaceable tongue 30 is pushed into a locked position from the long side edge when adjacent sort side edges are folded down to the sub floor.
  • a side push action could be difficult to combine with a simple angling and the friction may be too strong for wide panels.
  • Figure 1e shows a fold down system with a flexible tongue 30 that is made in one piece with the core.
  • Figure 1 f shows a long edge locking system in a fold down system that is connected with angling.
  • EP 2270291 A1 discloses a device having a core made of wooden material or wooden material-plastic mixture in a direction perpendicular to a visible side.
  • a groove is provided in a recess opened to a lower side and opened in a direction of the recess.
  • An upwardly aligned projection has another recess lying opposite to the groove.
  • a spring element e.g. a ring, is arranged in the latter recess and deformed in a direction parallel to the visible side in a compressed and/or deformable manner. The spring element is inserted into a structural panel.
  • WO 2011/012104 A2 discloses a covering comprising panels that can be connected to each other mechanically.
  • the covering has adjacent first and second panels, each having a groove on the sides thereof that are complementary to each other.
  • the grooves each have upper and lower groove sides having different lengths and in one of the grooves a spring is arranged that can be moved relative to the panel at least in parts.
  • the spring is suitable for engaging in the corresponding groove of the adjacent panel when the adjacent panels are connected, and the spring has at least one projection which points in the direction of the area of the longer groove sides of the other groove that protrudes relative to the shorter groove sides.
  • the projection is intended to be moved transversely to the laying plane of the panels in the event of contact with the area of the groove side, wherein the projection is operatively connected to a locking section of the spring.
  • the locking section can be moved in the direction of the groove of the adjacent panel as a result of the motion of the projection
  • An overall objective of embodiments of the present invention is to provide a locking system for primarily rectangular floor panels with long and short edges installed in parallel rows, which allows that the short edges may be locked to each other automatically without a snap action that creates a locking resistance and separation forces of the short edges during folding.
