Definitions

  • the invention relates to a panel with a panel core, a panel top with a wear layer, a panel underside and with edge pairs provided in pairs on opposite panel edges, at least one first edge pair being provided with complementary locking means, of which a locking means on a groove side of the edge pair as a locking groove and that Complementary locking means on a spring side of the pair of edges is designed as a locking spring which fits in a form-fitting manner with the locking groove, so that similar panels can be locked together, the locking tongue of a first panel being attachable to the locking groove of a second similar panel while tilting this panel, and then by a rotating one Joining movement of the panels relative to each other, both panels can be locked with one another in a form-fitting manner, so that the achievable positive locking locks the apart from moving counteracts the panel edges in a direction that lies in the plane of the locked panels and at the same time perpendicular to the locked panel edges, the locking spring on its spring top having a contact surface that is directed toward the top of the panel (the surface normal
  • a generic panel is from the EP 3 087 280 B1 known. Its overall thickness is relatively small. It can be 2 mm or less than 4 mm in total.
  • the panel edges of the known panel are designed in such a way that the panel edges can be profiled accordingly.
  • the known panel is also provided with a panel core made of a carrier material which has a matrix material comprising plastic. It contains a portion of solid material. According to one embodiment, the solid material is a mineral filler, for example talc.
  • the invention is based, in particular, on the fact that the panel core has a carrier material comprising a matrix and at least one filler provided therein in the form of particles, it being possible for the carrier material to have a certain fragility.
  • the filler is preferably a mineral filler, such as a layered silicate.
  • the design of the known panel has weaknesses in terms of the stability of the panel edges.
  • the free end of the locking spring has particular weaknesses; it can be damaged in particular by mechanical action from the outside prior to installation.
  • the carrier material has a structure with a certain brittleness, weaknesses occur in the known panel.
  • the invention has for its object to propose a panel that benefits from a shape of the panel core that improves stability.
  • the object is achieved in that a rounding on the contact surface connects to the front of the locking spring, that the rounding forms a free end of the locking spring with a round cross section, that a round transition to the underside of the spring is created, and that the rounding of the locking spring has a radius , which is the same size or larger than the distal extension of the contact surface.
  • the size of the radius of the curve is preferably in a range from 10% to 20% of the total thickness of the panel, particularly preferably in the range from 10% to 15% of this total thickness.
  • the cross section of the free end of the locking spring is designed as a relatively large radius. This measure has improved the stability of the panel edge equipped with the locking spring. Even if the panel core has a carrier material that tends to be fragile, the proposed panel turns out to be more stable than the prior art. In particular, it can be seen that a panel core made of a carrier material with a certain brittleness achieves better cohesion of the entire structure. Without being bound by this theory, it turns out to the inventor that something special arises when plate-shaped mineral particles, for example from talc, are used. The plate-shaped mineral particles are initially randomly embedded in a matrix during production. They are in a granulate during manufacture.
  • a certain orientation of the plate-shaped particles appears, predominantly in a direction parallel to the plate plane. This may be due to the fact that a certain orientation of the plate-shaped particles under the action of heat and one certain pressure, which is caused in a direction perpendicular to the plate plane.
  • the invention is preferably intended for panels which have a total thickness in the range from 2 to 6 mm, more preferably the total thickness is between 2.5 to 5 mm and particularly preferably between 2.8 and 4 mm.
  • the locking groove expediently has a groove base which is round in cross section and adjoins the contact surface of the upper groove wall, the groove base having a radius which is the same size or larger than the distal extension of the contact surface.
  • This groove base is further preferably adapted to the front rounding of the locking spring in such a way that, in the locked state, a small gap remains between the bottom of the groove and the rounding of the locking spring. This ensures that a closed joint is created above the locking spring when two panels are locked.
  • a further improvement of the panel can be achieved if the contact surface is inclined downwards in the distal direction, the angle of inclination of the contact surface with respect to the horizontal being in a range from 3 ° to 15 °, preferably 5 ° to 10 ° and particularly preferably 7 ° 9 °.
  • the panel level is usually aligned horizontally when two panels are locked.
  • the term “horizontal” means an orientation parallel to the plane of the panel or the top of the panel. Due to the inclination of the contact surface, in particular in the case of a panel core made of a carrier material that has brittleness, better cohesion can be achieved, which come to the surface in the region of the contact surface.
  • the curvature of the locking spring expediently merges into an outer surface that extends along the underside of the spring curved contour (convex).
  • the convex contour can be a radius.
  • the outwardly curved contour of the underside of the tongue is an outwardly curved radius, the center of which is located above the upper side of the panel.
  • This measure forms a relatively elongate spring underside. It works together with an equally elongated lower groove wall, which has a concave contour adapted to the underside of the tongue.
  • the curvatures of the bottom of the tongue and the lower groove wall are small and the area is relatively large.
  • the panel edge with the locking spring benefits from a high load-bearing capacity between the tongue underside and the lower groove wall when the top of the panel is loaded.
  • a tangential transition from the rounding of the free end of the locking spring into the convex contour of the underside of the spring is preferably provided. Dispensing with an angular transition also increases the stability of the panel edge or panel at this point.
  • the locking groove can have a short upper groove wall with a free end and a long lower groove wall on which a marginal strip is provided distally.
  • the edge strip has a holding surface and the surface normal of the holding surface points in the proximal direction. Arranged in this way, the holding surface can achieve a good holding force in order to counteract a movement of the panel edges apart perpendicularly from one another in the panel plane (horizontally).
  • the locking spring expediently has a counter-holding surface which is provided with a proximally oriented surface normal, and that the counter-holding surface in the locked state of two panels with the holding surface of the edge strip the lower groove wall interacts.
  • the concave contour of the lower groove wall can also rise in the direction of the edge strip and, together with the matching convex contour of the underside of the tongue, form an overlap that counteracts a movement of the panel edges apart in the above-mentioned horizontal direction, but this is by means of a pronounced holding surface and for this matching counter-holding surface achievable horizontal locking effect significantly improved.
  • the holding surface of the edge strip and the counter-holding surface of the locking spring are arranged parallel to one another in the locked state and at the same time relative to the solder of the top of the panel in an angular range from -10 ° to + 10 °, preferably -5 ° to + 5 ° are arranged. If the holding surface / counter-holding surface is in the negative part of the angular range, there is an additional undercut between these two surfaces. Due to the additional undercut, locking is also effected in a direction perpendicular to the panel plane (vertical). To produce the lock, it is necessary during the joining process to have a certain elastic deformation in the area of the locking means in order to produce the additional undercut and to bring the holding surface into engagement with the counter-holding surface.
  • the locking means can be connected to one another without elastic deformation and the locked state can be produced more easily. Then locked panel edges only have a locking effect in the horizontal direction. This locking effect is the better the lower the angle of inclination of the solder on the panel surface differs.
  • an abutment surface At the free end of the upper groove wall there is useful an abutment surface, the panel edge with the locking spring above it having a counter abutment surface which, when two panel edges are locked together, cooperates with the abutment surface of the upper groove wall.
  • the mating surface / mating surface limits the joining movement during the production of the lock, i.e. the locking spring can then not be moved deeper into the locking groove.
  • a closed joint forms between the panel edges involved on the top of the panel.
  • Both the abutting surface mentioned and the counter-abutting surface are expediently arranged perpendicular to the plane of the panel. If a certain contact pressure occurs that presses the abutment surface and the counter-closing surface against one another, then these surfaces can absorb the contact pressure. There is then no risk that the two surfaces will slide relative to each other and that there may be a height offset on the top of the panel. If the pairing of the abutment surface / counter-abutment surface were inclined with respect to the solder of the panel plane, a relative displacement of these surfaces would be risked, which could have a disadvantageous effect on the top side of the panel.
  • the lower groove wall has a recess at the transition to the edge strip, the recess merging into the holding surface of the edge strip.
  • This measure is advantageously accompanied by the fact that the holding surface at its lower end can be better used. For example, it can also extend somewhat deeper down into the recess. At least the recess creates a cut-out area that helps the underside of the spring to settle freely and that The counter-holding surface of the locking spring can position exactly on the holding surface of the edge strip of the lower groove wall.
  • the edge strip can alternatively be designed somewhat higher in order to enlarge the holding surface upwards and to give it the desired stability.
  • the top of the panel has an edge break on that panel edge with the locking groove and / or has an edge break on the panel edge with the locking spring.
  • a panel edge can also be improved in the area of the upper side of the panel, because a broken edge, which can be designed, for example, as a phase or radius, acts as edge protection.
  • the locking spring has on its upper side a distal extension from the mating surface to the free end of the locking spring.
  • two locked panel edges each have an edge break, for example one chamfer each
  • two edge breaks form a common free space.
  • the common free space can be, for example, a V-shaped free space (V-joint). It is preferred if the width of the common free space is greater than the distal extension of the top of the locking spring.
  • the front part of the locking spring should have a cross section which is approximately the same size as the free cross section of the free space.
  • the front part of the locking spring can have a cross section that is to a certain extent smaller or to a certain extent larger than the free cross section of the free space.
  • the cross section of the front part of the locking spring should then be in the range of 80-120% of the size of the cross section of the free space.
  • the width of the edge break and / or its depth can be in a range from 5% to 20%, based on the total thickness of the panel.
  • the dimensions of the edge break are related to the size of the radius of the curve of the locking spring; there is a certain overlap based on the total thickness of the panel, because the radius should be in the range of 10% - 20% of the total thickness.
  • Fig. 1 shows an embodiment of a panel according to the invention.
  • the panel is shown divided in order to be able to represent its opposite panel edges 1 and 1 'and their complementary locking means 2 and 3 in the locked state.
  • the panel edges shown in detail can also be understood as a representation of two panels which are not severed.
  • the design according to the invention is preferably provided so that the stressed panels can be made with a small overall thickness.
  • the small overall thickness should be possible even if the panel core is made of a carrier material that has fragility.
  • the panel according to Fig. 1 consequently has a panel core 4 made of a carrier material, which has a plastic as the matrix material.
  • a portion of solid material is provided as a filler, namely a mineral filler in the form of talc.
  • This carrier material has a certain fragility due to the filler.
  • Fig. 1 Basically it is about Fig. 1 around a panel with a top side 5 of the panel with a wear layer 6, a bottom side 7 of the panel as well as with panel edges 1 or 1 ′ lying opposite one another in pairs, which form a pair of edges.
  • the edge pair shown has complementary locking means 2 or 3 with a tongue and groove profile, namely a locking groove 8 on a groove side of the edge pair and a locking spring 9 on a tongue side of the edge pair.
  • this edge pair acts positively against moving two panels apart perpendicular to the locked panel edges and away from each other.
