Definitions

  • the invention relates to a floor panel according to the preamble of claim 1.
  • a floor panel which has connecting means for locking in a transverse and vertical direction at a first side edge.
  • These locking means are arranged on the longitudinal side of the panel and effect the locking by inserting and pivoting the connecting means into a corresponding recess of a second panel.
  • the transverse side of the panel has two snap hooks, which engage in corresponding undercuts of an adjacent panel during installation and impede the vertical movement between the laid panels.
  • the two snap hooks lie in vertical direction with each other.
  • a disadvantage of such a profile is the fact that such a profile design does not ensure a secure locking of the panels with each other, since the snap hooks arranged one below the other are pressed in during the laying movement and, in the case of a resilient substrate, for example a carpet, in a strong occurrence, the transverse side jumps out of the lock. This is also due to the fact that the provided with the Einschnapphaken panel relative to the corresponding panel in an occurrence slightly angled, so that the panel is virtually unscrewed.
  • the WO 01/02669 A1 describes a panel and a fastening system for panels to be laid on a substrate and the narrow sides are provided with retaining profiles, the retaining profiles of the opposite sides fit together so that more panels can be fastened to the free sides of a laid panel, wherein form-fitting elements are formed, by which the panels are fastened together by a rotating joining movement.
  • the interlocking elements are designed so that they form a common joint in the installed state of two panels and that the shape is created so that a freedom of movement for the common joint is created. This makes it possible that two interconnected panels can be bent at the junction up.
  • the DE 202 03 311 U1 describes a panel element for forming a floor, wall or ceiling covering of a plurality of similar, interconnected panel elements.
  • a rib extending in the direction of the underside and a correspondingly shaped retaining channel are formed on the other side edge.
  • the rib and the retaining channel have a defined first contact point, which defines two adjacent panel elements in a direction parallel to the panel surface.
  • a second contact zone is provided which defines two adjacent panel elements in a direction perpendicular to the panel surface.
  • the second contact point is arranged with respect to the first contact point such that, as part of the movement of the rib into the retaining channel, engagement occurs in the region of the first contact point after the start of the engagement.
  • the WO 2004/001157 A1 as an older, post-published document, relates to a panel member having a first longitudinal side with a spring, one of the first longitudinal side opposite the second longitudinal side with a spring of the same design groove, wherein the spring has a projection which projects beyond a side edge of a wear layer.

Support areas are aligned substantially horizontally.
  • the WO02 / 103135 A1 as a post-published document relates to plates with laterally arranged locking elements, with which two plates can be laterally connected by a form-fitting without glue.
  • Bearing surfaces have a slope to the horizontal.
  • the DE 100 21 897 A1 relates to a plate with a groove and a correspondingly shaped spring.
  • the groove profile has an inclined surface extending to the contact surface, which rests in the assembled state on a contact surface of the spring profile.
  • a projecting portion of the spring profile engages in the assembled state in the groove profile and is held like a wedge in the groove profile.
  • a support area is designed in such an angle to the horizontal that a sliding out of the spring is conveyed out of the groove.
  • the DE 201 21 196 U1 describes a generic Gebaudeplatte, in particular a floor panel, for connecting and locking a plurality of building panels together, in which mutually opposite side edges mutually corresponding groove and tongue.
  • the tongue and groove in each case have corresponding recesses, so that they allow each other to be aligned with one another to insert the spring into the groove. To lock the building panels they are shifted from each other in the longitudinal extension of the tongue and groove.
