Definitions

  • the invention relates to floorboards.
  • floorboards is subsequently any Floor covering construed in which at least two identically constructed elements be engaged with each other.
  • Examples of claimed in the invention floorboards are under other prefabricated parquet with a wear layer, the manner of a Schiffsêtparquet or designed in the manner of a plank.
  • the floorboards also count Three-layer planks, consisting of three layers of approximately equal thickness, preferably solid wood or veneer are constructed.
  • Floor boards, in the context of the invention are often composed of three layers. Examples for this are Prefabricated parquet with a thin layer of veneer or solid wood, a central layer made of glued or glued sticks and a counterpoise of inferior Veneer or solid wood. The layers are about 90 ° with the main fiber direction offset to each other to achieve maximum dimensional stability. Layered boards are usually of three approximately equally strong and qualitatively approximately equal layers of Solid wood or veneer built. Veneer or bar racks are on individual products also by wood material layers or plates to replace.
  • WO 00/47841 proposes floor panels on all sides with a Provide profile, in which a perpendicular to the plate plane to be closed connection is proposed, which provides groove, spring and locking elements.
  • the locking elements should have a horizontal contact surface and a shifting of the Prevent floor panels perpendicular to the board plane.
  • the locking elements should be elastic.
  • the disadvantage of this solution is that either separate Components must be inserted or glued, the parts of the locking elements and which are positioned very precisely for exact locking have to. This is laborious.
  • Another disadvantage is that the locking elements when joining can be easily damaged when on the in WO 00/47841 proposed manner have horizontal contact surfaces.
  • the elastic deformability of spring or tongue and groove so the deflection of Spring or tongue and groove when joining the profile or second floor elements also contribute to the protection of the locking elements and of the groove and spring at.
  • the deflection of the spring or tongue and groove protects the corresponding Locking elements when joining the floorboards be engaged with each other.
  • the floor elements or floorboards to be joined are in their horizontal Position set particularly effective to each other when tongue and groove formed as a cone are. This positive connection of the profile fixes the two floorboards in a simple and secure way.
  • the conicity of tongue and groove can be maintained be, even if corresponding locking elements or special Embodiments of tongue and groove are provided. It is enough if tongue and groove at least partially designed for conical engagement.
  • the spring of the profile is designed so that that it is deflected when joining the profile, and then after that Engagement of tongue and groove again assume the starting position.
  • This elasticity can be made by giving the required clearance for the engagement of a lip the groove is required, so deeply worked out that the remaining connecting bar allows the profile or the floor element deflecting the spring.
  • the spring of the profile is in two parts educated.
  • a first spring part is elastic, a second spring part is rigidly formed.

  • An embodiment of the profile according to the invention, with a joint-free assembly ensures the front sides of floor elements in a simple manner is designed so that the spring is a first part of a corresponding Locking element has that with a second part of the corresponding Locking element can be engaged. This second part of the corresponding Locking element is attached to a short, free lip of the groove and points to the spring.
  • the profile according to the invention requires a certain elasticity of the material. Brittle Material such. As high density fiberboard or materials with low bending strength such as As chipboard, are not well suited for the production of the above Profile. It is therefore preferred if plastic, solid wood or plywood for Production of the profile can be used. These materials have good machinability with known tools on a sufficient elasticity to the reliable Ensuring the functioning of the profile.
  • the profile according to the invention can, depending on requirements, either prefabricated as a separate component be mounted on end faces of floor elements, for example, by gluing in a groove in the front. Is the material suitable? the floor element, z. B. in the case of a solid wood floorboard, then the profile according to the invention is milled out integrally from the material of the floor element become.
