Definitions

  • the invention relates to a system of panels, in particular floor panels, with the features of the preamble of claim 1.
  • Such panels are typically used for a floor covering, such as parquet or laminate flooring, or for ceiling and wall coverings.
  • the individual panels can be combined by a mechanical connection to a flat whole, so that laying the panels without adhesives or additional mechanical fasteners, eg. B. Screws or nails is possible.
  • additional mechanical fasteners eg. B. Screws or nails.
  • the panels are preferably used as a floor panel and consist for example of
  • Laminate floor panels or lacquered floor panels are in turn preferably made of a wood material. Suitable wood-based materials include other medium-density fiberboard (MDF), high-density fiberboard (HDF), chipboard or Oriented Strand Boards (OSB).
  • MDF medium-density fiberboard
  • HDF high-density fiberboard
  • OSB Oriented Strand Boards
  • the panels may also be made of wood in the form of parquet strips or panels or of a plastic. The panels can also be used for other uses, such as wall or ceiling panels.
  • BESTATIGUNGSKOPIE WO 94/26999 and WO 97/47834 describe profile geometries which each have a tongue and groove connection for vertical locking.
  • the profiles have a hori zontal locking, in which a pair of generally obliquely to the top of the panels aligned Verriegelungsf is provided surfaces. The locking surfaces for the horizontal locking come into engagement with each other during the connection by a latching operation.
  • Detent process means that the locking elements for the horizontal locking of the first side edge of a first panel s laugh with the Verriegelungsf the hori zontal locking of the second side edge of a second panel come into contact.
  • at least one element of the connection is bent during the process of connection, so that it comes to latching, that is to say the element is bent back. Therefore, a mechanical resistance is in each case to be overcome in the joints, irrespective of whether the panels are pushed horizontally toward one another or whether they are brought into engagement with one another by a pivoting movement.
  • the connections are therefore also called detent or snap connections.
  • RO / nk 041254G Panels are built forces that can deform in particular the fasteners of the horizontal connection. A bad fit in the vertical direction is then the result.
  • the present invention is therefore based on the technical problem of providing a panel in which on the one hand the accuracy of fit remains sufficiently maintained and on the other hand, the disturbing creaking in the connecting elements is avoided under load. Another technical problem is to produce the panels with the lowest possible material consumption.
  • the system includes at least a first panel having at least one side edge having a groove formed by an upper lip and a lower 'lip, and at least one second panel having at least one side edge with a spring
  • a locking groove is arranged and on the underside of the spring, a locking projection is arranged.
  • a contact surface is arranged and above the spring, a contact surface is arranged.
  • the groove has a substantially equal width on both sides of the locking groove and the spring has a substantially equal thickness on both sides of the locking projection, the width of the groove and the thickness of the spring coincide.
  • the locking groove has a locking surface arranged towards the distal end of the groove
  • the locking projection has a locking surface arranged facing away from the distal end of the tongue.
  • both the upper surfaces of the groove and the upper surfaces of the spring and arranged on both sides of the locking groove lower surfaces of the groove and arranged on both sides of the locking projection lower surfaces of the spring abut each other and thus cause the vertical locking.
  • the contact surfaces and the locking surfaces cause a horizontal lock, wherein in the horizontal direction, a mechanical clearance is provided, which corresponds to the sum of the horizontal distance between the contact surfaces and the horizontal distance between the locking surfaces.
  • RO / nk 041254G by the concerns of the tongue and groove surfaces creates a stable connection, although a game is present in the connection.
  • the play ensures that the connection between the locking elements is not under a bias by which the two panels are biased towards each other. In particular, it is prevented by the play that a strong friction between the abutting upper abutment surfaces arises under a load of the region of the abutting edge of two panels. The loose in the size of the game connection can thus effectively avoid the occurrence of a creak.
  • the game is preferably kept small and is in the range of 0, 01 mm to 0, 10 mm, in particular from 0, 01 mm to 0, 05 mm and in particular from 0, 02 mm to 0, 05 mm. Therefore, the game has just been chosen so large that on the one hand the function of the connection between each two panels is guaranteed without the occurrence of a creak and so on the other hand no too large gap formation, so a formation of visible columns occurs. Under visible columns is
  • a resulting further advantage arises in the case of a floor laid from the previously described panels with a shrinkage and expansion process occurring as a result of a seasonal change.
  • strong tensile forces which act in particular on the short interconnected side edges.
  • a visible gap appear on a weaker side edge, that is to say in a size that is conspicuous to a viewer.
  • For the relief of at least part of the tension is distributed evenly over all side edges by the game contained in each connection leads to uniform opening behavior along the row.
  • all side edges of the series are relieved and only with a tensile stress occurring beyond it can lead to an enlarged opening of the side edges or only individual side edges.
  • the horizontal abutment surface arranged near the front end of the lower lip of the groove and the corresponding abutment surface on the spring bring about a further advantage of the connection between in each case two panels.
  • the contact point between the tongue and groove at this point is located very close below the abutting edge between the two panels.
  • the force exerted on the spring panel is so strong that it has to dodge by a predetermined path down.
  • the contact surface at the front end of the lower lip is advantageous. Because of the vertical movement above all, a force acts on a location remote from the base of the groove on the lower lip, so that because of the lever arm, the force to be applied is less than if the same movement would act on the groove bottom closer position on the lower lip. As a result, and also because of the overall larger area, the force and thus also the plastic deformations on the lower lip and on the spring are reduced. The lasting stability of the connection between the two panels is therefore improved.
  • the particular configuration of the connecting elements furthermore ensures that the forces occurring during the use of the panels can be absorbed better within the connection. It also means that cracks,
  • RO / nk 041254G which possibly arose during the addition with deflection of the lower lip, do not expand further and lead to an inaccurate fit of the connection.
  • a generation of a vertical offset at the abutting edge of the two panels is effectively prevented.
  • the profile geometry described causes the connection to move more easily as a hinge when forces are exerted by a load at unevenness of the ground.
  • the hinge movement prevents then because of the greater compared to a compound with bias margins excessive force into the compound.
  • too strong bending of the lower lip is prevented again, which would lead to a weakening of the compound in too frequent occurrence.
