Definitions

  • the invention relates to a registered trademark of a registered trademark of a registered trademark of a registered trademark of a registered trademark of a registered trademark of a registered trademark of a registered trademark of a registered trademark of a registered trademark of a registered trademark of a registered trademark of a registered trademark of a registered trademark of a registered trademark of a registered trademark of a registered trademark of a registered trademark of a registered trademark of a registered trademark of a registered trademark of a base, and at least two opposite sides each having a groove and a respective spring, wherein the Groove on the one hand is substantially congruent to the spring on the other side and the groove and the spring directly adjacent to each other.
  • Such a floor panel is for example from the DE 33 43 601 A1 known.
  • profile bars are provided on the edges to be joined, which are connected to each other by merely joining together in the transverse direction, that the plates are coupled to each other both to the plate plane and perpendicular to the plate plane.
  • the profile bars must be glued to the plate edges.
  • the side edges must be provided with corresponding recesses.
  • the panels are made of wood-based material, especially MDF or HDF.
  • the upper side is formed by a decorative layer applied to the MDF board.
  • Floor panels should be tight at the juncture of the top to prevent moisture from entering the junction, which would swell the panels of the panels. For this reason, the latching means are formed so that two nested panels are biased and at the top of the joints are firmly pressed together.
  • the panels must be connected to each other on the long sides as well as on the transverse sides. When laying the longitudinal sides are usually connected together first. Then the last scheduled panel must be moved in the longitudinal direction in order to connect to the transverse side can.
  • the CH 684 544 A5 discloses a floor panel, in particular for highly stressed floor coverings, each having a groove and a projection at the edge regions, the projection being congruent with the groove on the opposite side.
  • the plates are inserted into one another in such a way that the projection engages in the corresponding groove.
  • the DE 198 54 475 A1 discloses laminate panels provided with a tongue-and-groove joint adapted to connect two panels by angularly nesting and lowering a panel to be newly laid.
  • the spring is formed approximately in the middle of the plate on one side edge. On both sides, the spring is limited by grooves, which are directed into the core of the plate.
  • Laminate floor panels have a thickness of approx. 6 - 10 mm. The spring is dimensioned accordingly narrow. Due to the grooves introduced on both sides, the spring is additionally weakened.
  • the EP 1 045 083 A1 discloses a floor panel provided at one side edge with a spring and two grooves and at the opposite side edge with a groove and two springs machined integrally from the core of the panel. To connect two panels, they must be infiltrated and then lowered onto the subfloor.
  • the groove bottoms of the grooves are rounded as well as the tips of the springs.
  • Panels which can be interconnected by a purely vertical joining movement. If panels can be connected to each other both on the longitudinal side and on the transverse side only by a vertical joining movement, this has the consequence that the newly added panel must be pre-positioned very accurately. If the panel is not precisely aligned before lowering onto the subfloor and connecting with too high a force, there is a risk that the locking elements break off or tearing the side profiling, which is not recognizable from the outside when the floor panels are laid, but not permanently durable Connection between the panels can be obtained.
  • a generic floor panel is characterized by a core of wood-based material from which exactly one groove and exactly one spring is integrally formed on each side, and in each case a flat groove bottom in two grooves which are inclined at the same angle to the top.
  • the angle of inclination is preferably between 30 ° and 50 ° and in particular 45 °.
  • the spring is directed on one side to the bottom and the spring of the opposite side to the top. Accordingly, the groove of one side is open to the bottom and the groove of the opposite side to the top open.
  • the edges of the spring directed towards the underside are rounded, and preferably in addition the side edge closer to the upper side to the upper side When the open groove is rounded, the handling of the panels when nesting is simplified.
  • the groove open to the top has an undercut into which the spring directed towards the underside can engage with a correspondingly configured projection.
  • the panels are locked to each other.
  • the rounding radii for the spring and the groove are preferably identical.
  • the undercut can be formed by a fillet.
  • the floor panels 1, 2 consist of a core of wood-based material.
  • the upper side 13 has a decorative layer 11.
  • each panel 1, 2, each with a spring 3, 7 and a groove 4, 8 are provided.
  • the grooves 4, 8 directly adjoin the springs 3, 7, so that they have a common wall 4a, 8a.
  • the groove bottom 5, 9 of both grooves 4, 8 extends at an angle ⁇ of about 45 ° inclined to the top 13th
  • the wall 8a of the groove 8 opened to the upper side 13 runs perpendicular to its groove bottom 9.
  • the opposite wall is provided with an undercut 10 which has been produced by a fillet of radius r1.
  • the congruent to this groove 8 spring 3 on the opposite side is rounded at their edges with the radius r 2 , wherein the radii r 1 and r 2 are the same.
  • the facing away from the groove 4 wall 3a of the spring 3 is provided according to the undercut 10 with a bulge, so that in two interconnected panels 1, 2, the spring 3 is locked to the groove 8 by the bulge engages the undercut 10.
  • the groove bases 5, 9 are parallel to each other. Correspondingly inclined, the outer edges of the springs 3, 7 extend.
  • the surface 12 lies in an imaginary line with the groove bottom 9 and runs at the same angle ⁇ .
  • the panel 1, 2 On the opposite side is the panel 1, 2 at the bottom 14 with a Bevel 17 provided. Over the area formed by the chamfer 17, the panel 2 is supported on the surface 12 of the panel 1 when the panels 1, 2 are connected to each other.
  • FIG. 2 shows, formed by the rounded edges of the spring 3 at nested panels 1, 2 in the joint a cavity 18.
  • This cavity 18 serves as a dust bag.
  • a cavity 19 is formed between the perpendicular to the surface 13 extending wall 6 of the groove 4 and also perpendicular to the surface 13 extending side wall 7a of the spring 7, to avoid tension in the joint.
