Definitions

  • the invention relates to a panel element having a payload side, a counterpart opposite the payload side, a first side having a spring, a second side opposite the first side having a groove of the same design as the spring, wherein the spring has a connecting element which is substantially perpendicular to the Useful side extends and whose cross-section has a first edge and a second flank opposite the first flank, wherein the cross section of the connecting element has a center line extending perpendicular to the useful side.
  • the tongue and groove connection is produced by a movement perpendicular to the useful side. A shift of the panel elements parallel to the laying plane is not required.
  • a panel element in which the spring on the end face of the panel element has a hook element with an approximately circular cross-section and the groove has a diametrically opposed recess.
  • a disadvantage of the tongue and groove connection according to the DE 100 01 076 C1 is that a high force is required for connecting the spring with the groove, which is why it can easily occur in the laying of damage to the panel element, in particular the Nutzseite and / or the edges of the recess. If the edges of the recess are damaged, then the tongue and groove connection often has only a slight hold, whereby an undesired release of the tongue and groove connection can occur when the panel element is stressed.
  • Another disadvantage is that with repeated loosening and reassembly of the tongue and groove joint due to the deformations of the groove and / or the spring transferable forces of the tongue and groove connection can be greatly reduced.
  • the FR 2 278 876 A discloses a panel member with a spring having a hook member in the shape of a dovetail, wherein a flank of the dovetail is perpendicular to the useful side.
  • the groove also has a hook element in the shape of a dovetail, wherein a flank of the dovetail is perpendicular to the counter-pull.
  • a disadvantage of the panel element of FR 2 278 876 A is that only at one side of the hook element in the tongue and groove connection, a contact point is formed, so that the tongue and groove connection is not free of play due to manufacturing tolerances and against a climate-related dimensional change of the spring is given only little resistance.
  • WO 01/02670 A1 goes out a panel element with a spring, which has the shape of a dovetail, wherein a flank of the dovetail is perpendicular to the decorative side.
  • the groove also has the shape of a dovetail, with one flank of the dovetail being perpendicular to the counter-pull.
  • the panel element according to the WO 01/02670 is also disadvantageous that only at one side of the spring or the groove in the tongue and groove connection a contact point is formed, so that the tongue and groove connection is not free of play due to manufacturing tolerances.
  • the groove-and-tongue connection has in particular compared to a climate-induced dimensional change of the spring and / or the groove only a small resistance, since the spring can rotate relative to the groove.
  • the DE-U-202 03 311 discloses a panel member having a payload side, a payload side opposing counter, a second side opposite the first side with a tongue of the same configuration, the spring extending substantially perpendicular to the payload side and having two opposing flanks, wherein - in the direction of seen the useful side - in a first portion of the spring, the inclination of the first edge and the second edge respectively facing away from the center line of the spring cross-section and in a second portion, the inclination of the first edge facing away from the center line and the inclination of the second edge to the center line, wherein the distance is reduced perpendicular to the center line between the first and the second edge.
  • a rib is formed, which engages in the vertical connection between two adjacent panel elements, in a retaining channel of the adjacent panel member.
  • the object of the invention is to provide a panel element of the type mentioned, in which the known disadvantages are avoided, which allows a play-free tongue and groove connection, has a high resistance to climate-induced dimensional change of the spring and in which the production of the groove Spring connection required forces are as small as possible.
  • this is achieved in that - seen in the direction of the payload side (visible in the installed state top) - in a first portion of the connecting element, the inclination of the first edge, which is arranged on the side facing away from the panel element of the connecting element, and the second Edge facing away from the center line to the outside and in a second section, the inclination of the first edge facing away from the center line to the outside and the inclination of the second flank to Center line, wherein the distance is reduced perpendicular to the center line between the first edge and the second edge.
  • the latching resistance for the first edge and the second edge at different times has its maximum, whereby the required force and the risk of damage to the panel element according to the invention is reduced. Furthermore, because of this splitting of the detent resistors, the inclination on the two flanks of the connecting element in the first section points outward from the center line, so that a dovetail connection is provided in which at least one contact point is formed on the two flanks, whereby a good hold of the groove Spring connection against forces and moments, which act substantially perpendicular to the longitudinal axis of the spring is achieved. Due to the splitting of the maximum of the latching resistances, a greater inclination on the two flanks can furthermore be selected, and the risk of damage to the panel element due to the force required to produce the tongue and groove connection can be kept low.
  • the inclination of the first flank and the inclination of the second flank in the first section are each substantially constant.
  • This design corresponds to a conventional dovetail joint in the first section, which is easy to manufacture and gives a uniform stress distribution at the contact points.
  • the first flank in the first section has a lower inclination than the second flank.
  • the inclination is an essential measure of the transferable between the groove and the spring voltages normal to the decorative side, wherein at a greater slope greater voltages are transferable, without that the tongue and groove connection is released.
  • larger voltages normal to the decorative side than at the first edge are transferable to the second edge, whereby the transferable forces can be increased at a given contact surface on the second edge.
  • the inclination of the first flank in the second section is substantially constant and is the same as the inclination of the first flank in the first section. This results in a simple profile to be produced on the first flank, in which the latching resistance in the manufacture of the tongue and groove connection steadily decreases.
  • the second edge is rounded in the second section.
  • the rounded embodiment reduces the risk of stress peaks due to a notch effect.
  • the groove has a depression formed the same connection element and in the connected state of the tongue and groove connection on the first edge of the connecting element, a first contact point and on the second edge of the connecting element, a second contact point is trained.

  • the groove may have a further glue channel, wherein the further glue channel is arranged in the connected state of the tongue and groove connection adjacent to the end face of the spring. If the tongue and groove connection is adhesively bonded in the further glue channel by means of an adhesive, then it has a particularly high resistance to a dimensional change of the end face of the spring caused by the climate. Furthermore, the penetration of moisture into the region of the connecting element is prevented.
