Definitions

  • the invention relates to a floor panel according to the preamble of claim 1 and claim 33.
  • 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.
  • Object of the present invention is to provide a panel with which a simple installation is possible and the secure locking both in the transverse direction and in the vertical direction is ensured.
  • the object is achieved by a floor panel with the features of claim 1 and by a panel having the features of claim 33.
  • the method of laying such a profile allows a quick and easy installation, whereby the durable locking of the panels is ensured with each other.
  • the second side edge has, in one embodiment of the invention, an outgoing from the bottom, step-shaped cutout with an inner wall and an outer wall. On each of these walls, a form-locking element extending in the transverse direction is formed, preferably milled out, which engage in corresponding undercuts of a step-shaped cut-out of the second panel to be connected, starting from the upper side.
  • the outgoing from the top, stepped cutout also has an inner and an outer wall, where the corresponding Undercuts are formed so that it can come to a positive locking in the vertical direction at the second side edge.
  • the step-shaped cut-out starting from the underside has a shoulder projecting in the direction of the underside, which forms a substantially horizontally oriented head surface, this shoulder providing a locking effective in the transverse direction, perpendicular to the second side edge.
  • the substantially horizontally oriented head surface is used to set the minimum height offset and provides a relatively large contact surface for introducing vertically acting forces.
  • a further embodiment provides that in the top surface of the paragraph, a groove aligned in the longitudinal extent of the second side edge is incorporated. This grooving creates a dust bag that can be trapped in the abrasion or imperfections created during installation without adversely affecting installation accuracy.
  • the groove further causes a slight spring effect, so that the locking on the second side edge is under a certain bias.
  • the walls of the shoulder are aligned to the top surface at an acute angle, which has either an easy insertion into a corresponding recess of the corresponding cutout of the second panel or when forming an undercut to the top surface an additional locking effect result.
  • a transverse extension of the top surface in a range of 2 mm to 6 mm provides very good durability values and a very good locking effect, wherein preferably the top surface has 0.25 to 0.4 times the total transverse extent of the step-shaped cut-out.
  • a particularly effective and simple locking on the second side edge is given when a positive locking element projects horizontally beyond the terminal edge of the top. It may be appropriate that between the Top and the excellent positive locking element is arranged a recess which undercuts the end edge of the panel to accommodate any existing abrasion or deforming material of the panel, so that a precise fit possible with minimal gap width is possible because no abraded or deformed material exerts a barrier effect ,
  • the side edge of the panel opposite the second side edge has a step-shaped cutout projecting from the upper side, with a shoulder projecting in the direction of the upper side.
  • This paragraph also has a substantially horizontally oriented head surface, wherein in the lower region of the Absatzau present inventor an undercut is formed, which corresponds to the corresponding positive locking element of the inner wall of the male side edge.
  • the arrangement of the recess in the lower portion of the Absatzau towandung increases the effectiveness of the lock.
  • a further development provides that a horizontal base surface is formed between the inner wall of the recess and the inner wall of the cutout, which is designed in such a way that, when the panels are laid, the top surface rests on the base surface and the tops of the panels lie in one plane, which means There is a minimum or no height offset between the panels. Due to the interaction of horizontal base surfaces and top surfaces, a particularly accurate assignment and adjustment of the height offset is possible, as well as the Abwinkelne Trent adjacent panels is reduced, which increases the strength of the lock.
  • the heel inside of the cutout emanating from the top extends parallel or at a shallower angle than the corresponding heel inside of the laid-in heel to either make a precise fit or provide a component of movement for the two panels in the transverse direction.
  • the upwardly projecting shoulder of the cutout emanating from the top is not formed over the entire length of the second side edge, but is in particular at an end region of the second side edge, which is in the direction of the spring-loaded first Side edge is directed, milled to the base surface or not formed.
  • the removal or non-formation of the protruding shoulder facilitates pivoting about the axis parallel to the first side edge, so that a blocking effect by the positive locking elements only takes place when the adjacent at the second and the opposite side edge panels at an acute angle to each other lie. This means that only a short distance in the vertical direction must be covered in order to fully lock the panels at the second and opposite side edge.
  • the formation of the recess as a groove with an upper lip and a lower lip ensures that a reliable assignment of the panels to be laid is done to each other, so that a minimum height offset of the panels can be achieved, which is a quality feature in floor panels.
  • the spring is latched in the transverse direction in the groove, wherein the lower front portion of the spring rounded to allow easy pivoting into the corresponding, trained groove.
  • the spring is rounded at the bottom to allow easy pivoting into the groove.
  • the underside of the spring has a continuous curved contour, wherein the radius of curvature of the contour of the underside of the spring remains substantially constant over at least 90 °, so that a uniform pivoting movement and a simple sliding on the corresponding Recess can be made.
  • the positive-locking element on the wall is a projection and on the front shoulder a corresponding recess, which were produced by a corresponding cutout.
  • an upper side of the spring rests in the mounted state on an underside of the upper lip in order to effect a further positive locking.
  • the parallel formation of the underside of the spring and the top of the lower lip to the top of the panels allows a large-area support of a panel on the other panels, so that a low surface pressure in the tongue and groove connection prevails and a very low height offset of the panels can be realized to each other.
  • the formation of the recess as a groove with an upper lip and a lower lip ensures that a reliable assignment of the panels to be laid is done to each other, so that a minimal height offset of the panels can be achieved, which is a quality feature in floor panels.
  • the spring is latched in the transverse direction in the recess, wherein the spring and the recess in cross section have a wedge-shaped contour to allow easy insertion and to achieve a good self-centering of the spring in the groove.
  • the spring and the recess are formed such that in the assembled state between the front of the spring and the adjoining the upper lip area the recess has a gap in which the abrasion can accumulate and serves as a movement space of the two panels each other.
  • the gap tapers toward the front lip of the lower lip to provide a smooth transition between the areas of full surface area and clearance for moving and accumulating debris.
  • Any existing abrasion can also be absorbed in a space formed between the spring and the top of the panels by an undercut.
  • the distal end of the spring is formed vertically and serves as a conclusion of the first side edge.
  • Corresponding to the groove bottom is also formed perpendicular to the top, so that a good assignment of the panels can be made in the transverse direction.
  • a substantially flat surface at an angle to the horizontal, preferably 45 °, is formed in the rear region of the spring. This surface interacts with a corresponding projection in the groove of the adjacent panels and causes a locking in the transverse direction, so that slipping perpendicular to the first side edge is effectively prevented.
  • the spring is adjoined by a support region for supporting on a shoulder terminating the groove of the second panel, which increases the effective contact surface and allows a uniform distribution of force.
  • the support area extends substantially horizontally, but may have a slight inclination to the horizontal to effect a horizontal movement under vertical load.

  • the recess is formed as a groove with an upper lip and a lower lip, in which the spring is latched in the transverse direction, the lower front portion of the spring is rounded and connects to the rounded front portion of the spring a flattened, substantially horizontally extending support area.
