Definitions

  • the invention relates to a system of at least two panels, in particular floor panels, for forming a covering, the two panels having a first side edge and a second side edge opposite the first side edge, the first side edge and the second side edge connecting the first side edge of a panel formed with the second side edge of another panel by a movement substantially perpendicular to the covering, wherein the first side edge has a locking bar and a spring means, wherein the second side edge has a locking element cooperating with the locking bar, wherein the locking bar in one piece from a carrier layer of the panel and is designed to be movable, so that the locking bolt can assume an outer position and an inner position relative to the first side edge, wherein the spring means is coupled to the locking bolt such that the spring means in the inner position a croqu restoring force on the locking latch in the direction of the outer position, wherein the locking bar and the locking element each having a locking surface, wherein the locking surface of the locking bar to the underside of the panel and is provided at a free end of the locking bar, wherein in
  • Panels of this type can be connected to one another to form a floor covering, in particular floor covering.
  • the first and second side edges of adjacent panels are therefore formed corresponding to each other.
  • the joining of each of the first and the second side edges of adjacent panels is effected by a movement which is substantially perpendicular to the floor covering, in the case of a floor covering substantially vertically.
  • the panels thus differ quite fundamentally from those in which the first and second side edges are incised into one another by means of a pivoting movement or are pushed into one another by a movement substantially parallel to the covering.
  • Such panels are for example from the WO 97/47834 A1 known.
  • the first and second side edges of the panels of the type mentioned have locking latch and locking elements which engage with each other in the connected state.
  • the panels can then no longer against each other be lifted off to the top. So there is a locking substantially perpendicular to the covering.
  • an additional locking of the panels can take place substantially parallel to the covering.
  • the first and second side edges of the panels are therefore to be laid without the use of glue or other fasteners, such as screws or nails.
  • floor panels are understood to mean, in particular, laminate floor panels.
  • Laminated floor panels generally have at least one layer with a resin-soaked decorative paper and at least one counter-tensile layer with a likewise resin-impregnated paper on both sides of a so-called carrier layer.
  • the base body of the panels forming carrier layer is made in particular of a wood material. Suitable wood-based materials are, for example, medium-density fiberboard (MDF), high-density fibreboard (HDF), chipboard or Oriented Strand Boards (OSB).
  • MDF medium-density fiberboard
  • HDF high-density fibreboard
  • OSB Oriented Strand Boards
  • solid wood a wood / plastic composite or a compact board made from pressed, resin-impregnated papers as a carrier material.
  • Panels of the type mentioned are approximately from the EP 1 518 032 A1 known.
  • the opposing first and second side edges of the panels are formed corresponding to each other.
  • the second side edge can be connected to the first side edge from above, ie substantially perpendicular to the covering. In the connected state, the panels can not be lifted upwards, since it is at Connecting to a latching operation between a locking lip and a locking lug of the side edges comes.
  • the locking lip and the locking lug are matched to one another such that the locking lug presses against the locking lip during connection.
  • the locking lip has the necessary flexibility to consequently be pushed from an outer position relative to the first side edge to an inner position.
  • the flexibility of the locking lip is provided by an elasticity groove adjacent to the locking lip, which may be filled with an elastic means as needed to adjust the flexibility.
  • the locking lip If the locking lip is forced to the inner position, the locking lug can slide past the locking lip. Subsequently, the locking lip springs back into its outer position and engages behind the locking lug of the adjacent side edge. Thus, corresponding locking surfaces of locking lip and locking lug come into abutment with each other, which are each slightly inclined relative to the plane of the lining.
  • the necessary elasticity of the locking bar for the spring back of the same is also provided, if necessary, essentially by the spring means.
  • the locking lip is formed integrally with the carrier layer of the panel. When connecting two side edges, however, the locking lip may break. If the elastic means is a type of glue, the locking lip will remain on the panel despite such breakage fixed. The locking of the side edges perpendicular to the floor covering is retained. However, a connection with a broken locking lip can only absorb reduced vertical pull-out forces, depending on the elastic means. At high loads, it may therefore come to a height offset of the connected panels. If the load continues to increase, the panels may become disengaged due to the offset in height, or may permanently rupture the locking lip.
  • Systems of panels with corresponding side edges to form floor coverings which can be connected by a substantially vertical movement to the floor covering and locked by means of a movable locking bolt are, for example, from WO 2011/001326 A2 and the WO 2009/080328 A1 known.
  • the WO 2008/060232 A1 from which the invention proceeds, also has a spring means in the form of an elastic mass for adjusting the restoring force of the locking bolt.
  • the invention is based on the technical problem to provide a system of panels of the type mentioned, with the higher vertical extraction forces can be ensured.
  • the first and second side edges become substantially perpendicular to the covering to be produced from the panels by a movement in one direction connected.
  • the connection of the first and second side edges does not have to be exactly perpendicular to the covering. It is sufficient if the movement for connecting the first and the second side edges runs predominantly from top to bottom.
  • a movement essentially perpendicular to the covering can be understood to mean a movement which runs predominantly perpendicularly (> 45 °) to the covering. However, the movement will preferably have an angle of> 70 ° to the covering.
  • the first and the second side edge can also be connected by a pivoting movement about another side edge.
  • one end of the first side edge may be in engagement with the second side edge rather than the other end of the first side edge.
  • the second side edge is pushed from the top to the first side edge.
  • the locking bar having first side edge is preferably already on the ground.
  • the locking member then approaches the locking latch from above and pushes the locking latch against the panel from the outer position to the inner position. If the locking element has passed the locking bar, this is pressed by the spring means in the direction of the possibly original, outer position, so that the locking bolt and the locking element lock together. In the connected state, the locking element engages under the locking latch.

  • the locking bar It is advisable for a permanent locking of the side edges, to manufacture the locking bar of a material or with such dimensions that it is not excessively compressed. It also makes sense if the locking bar is supported against a part of the first side edge, which can absorb the forces introduced via the locking bar, without being unduly deformed or destroyed. The corresponding part of the first side edge therefore points as well as the locking bar preferably has a high rigidity and strength.
  • the locking bar may be formed so that it breaks in an excessive load in a predictable manner. It can therefore be provided a kind of predetermined breaking point.
  • the locking bolt may be formed so that a possible fracture plane extends at an obtuse angle to the force acting on the locking bolt when lifting the second side edge. The sharper this angle is, the higher is the risk that the two break edges created by the break will slip against each other and the first and second side edges will no longer be locked perpendicularly to the lining.
  • the locking surface of the locking bar faces downward, i. to the bottom of the panel.
  • the locking bar is pressed up against the panel. In this way, high extraction forces can be absorbed by the connection between a first and a second side edge even with a broken locking bolt.
