  • the invention relates to a panel with a panel core, a panel top, a panel bottom and with at least one pair of edges of opposing complementary panel edges, which are provided with complementary locking means, the complementary locking means being designed in such a way that when two of these panels are assembled, they are below a visible joint
  • complementary locking means By means of the assembled complementary locking means, a locking effect of the panel edges can be achieved both in a direction perpendicular to the top of the panel, and a locking effect against the panels moving apart, namely within the panel plane away from one another, can be achieved in a direction perpendicular to the locked panel edges, with the proviso that that the panel edges provided with the complementary locking means have an upper portion and a lower portion based on the thickness of the panel, the complementary locking means being arranged and designed in the lower portion of the panel edges, the upper portion of the panel edges being included for the design of the upper joint area the visible part of the joint is provided and for this purpose the upper part on each panel edge of the pair of edges has an edge break, which forms
  • the assembled state of panels or complementary panel edges basically means the desired state.
  • a panel which has a joint design without recess in the upper part and has positive locking means in the lower part, which are designed in the form of a groove profile and a tongue profile.
  • An example of a panel which has complementary panel edges, which in an upper part area, based on the thickness of the panel, have a design with edge refractions of different sizes in the form of a larger chamfer and a smaller chamfer.
  • the upper portions of the panel edges are further designed in such a way that two of these panels form a V-joint when assembled form, with the larger bevel being partially covered by the smaller bevel.
  • this prior art defines a neutral position of the panel edges relative to one another, from which the panel edges can move closer to one another or further away from one another. In the neutral position, the V-joint is not closed at the base of the joint, but a gap remains there.
  • the complementary locking means provided in the lower part of the complementary panel edges from the same prior art appear to be of little load-bearing capacity and their durability is unsatisfactory.
  • a panel which is described as semi-floating planks/building panels with mechanical connection systems, a core with curved edge sections so that the surface layer on the top of the core is below the panel surface, the edges of the plank having a bevel, in the connection system
  • the surface layer and a part of the core of the connecting edge portion in the second connecting edge overlaps the surface layer which is substantially parallel to the horizontal plane of the first connecting edge of the other plank.
  • floorboards/building panels are to be produced by processing the surface structure with a large number of core grooves and applying the cover layer to the top of the core in order to at least partially cover a floor element.
  • a generic panel is from the CN 107 938 992_A known, which according to claim 1 relates to a plug-in structure for parquet floors, which is characterized in that it comprises a first panel body and a second panel body, wherein adjacent ends of the first panel body and the second panel body are connected by a plug-in mechanism and the first panel body is connected.
  • An upper portion of the side is chamfered, and the bevel is an internal concave curve.
  • the invention is based on the object of proposing a panel which has an improved design with edge breaks in the upper part of the panel edges and which ensures that the joint is closed when assembled.
  • the object is achieved in that the counter-impact surface is arranged below the smaller edge refraction in a direction which runs through the smaller edge refraction (5).
  • the two edge breaks can be designed as a chamfer, as a radius or as a fillet, etc.
  • the pairing of blunt abutting surface and counter-butting surface provided in the upper part of the panel edges interacts with the locking means arranged in the lower part of the panel edges, with which the Locking effect is effected against moving the panels apart within the panel plane and perpendicular to the locked panel edges. In this way, the closure of the joint desired in the upper part of the panel edge is supported by the locking means provided in the lower part.
  • the panel edge with the smaller of the two edge breaks has an undercut counter surface below this smaller edge break for the covered part of the larger edge break.
  • the covered part of the larger edge refraction expediently has surface contact with the undercut counter surface. This also improves the integrity of the joint and counteracts the penetration of dirt and moisture.
  • the benefit can be further improved if the abutment surface and the counter-abutment surface are prepared in such a way that when two complementary panel edges are joined together, a wedge-shaped gap is formed between the abutment surface and the counter-abutment surface so that the tip of the gap points upwards towards the top of the panel.
  • the wedge-shaped gap between the abutment surface and the counter-abutment surface promotes relative movement of two mated interlocked panels.
  • the panels can develop a kink along the interlocked panel edges as a pivot point if, for example, they are placed on an uneven surface. Can do this locked panels assume a position relative to each other in which their panel surfaces lie at an angle > 180° to one another. In this case, the wedge-shaped gap creates space within the interlocked panel edges the required angular movement of the panel edges.
  • the blunt abutment surface and the counter-abutment surface maintain contact and an opening of the joint is counteracted.
  • the blunt abutment surface and the counter-abutment surface touch each other at the tip of the wedge-shaped gap.
  • the wedge-shaped gap can have a wedge angle in the range of 0° - 10° and preferably from 1° - 5°, with a central axis of the wedge-shaped gap bisecting the wedge angle being arranged either perpendicular to the top of the panel or relative to the plumb line on the top of the panel in an angular range of ⁇ 5° is arranged.
  • the complementary locking means are designed as complementary hook profiles, namely an upwardly open receiving hook and a downwardly open locking hook, so that both complementary hook profiles have holding surfaces provided in one piece on the panel core, by means of which the locking effect is counteracted the movement of the panels apart within the panel plane away from each other in a direction perpendicular to the locked panel edges can be achieved, and that a separate locking element is provided for the locking effect in the vertical direction perpendicular to the top of the panel, as in the EP 1 415 056 B1 defined or in the WO 2011/087425 A1 suggested.
  • the separate locking element can be mounted on one of the complementary panel edges and have a latching means with which it can be latched into a latching contour of the complementary panel edge.
  • a technical solution other than the aforementioned locking means with hook profiles does not require a separate locking element and provides that locking means comprising a groove profile and a complementary tongue profile are provided in the lower part of the complementary panel edges, the groove profile and the complementary tongue profile having those holding surfaces by means of which the locking effect can be achieved against the panels moving apart within the panel plane away from one another in a direction perpendicular to the locked panel edges, and that the tongue profile has a contact surface on its tongue top and the groove profile has a complementary inner surface on an upper groove wall, which means that in the assembled state Locking effect can be achieved in the vertical direction perpendicular to the top of the panel.
  • the design of the lower portion of the complementary panel edges with locking means if they are designed as a groove profile and complementary tongue profile, as described above, is viewed as an independent invention, which can alternatively do without the design of the upper portion of the complementary panel edges proposed above.
  • the panel edges can then have any design; for example, no edge breakage can be dispensed with, so that no recessed joint occurs on the surface between two locked panels. This applies equally to all subsequent further developments of the panel with a groove profile and complementary tongue profile.
  • the lower groove wall advantageously protrudes further distally from the panel edge than the upper groove wall, with a retaining edge being provided at the free end of the lower groove wall, and the retaining surface for the locking effect against moving the panels apart in the panel plane being provided on said retaining edge .
  • the groove profile and the tongue profile are helpfully prepared for a snap lock, in which two identical panels are locked perpendicularly to one another by a plane displacement of the panel edges and/or are prepared in such a way that a panel can be locked with an identical panel by a pivoting movement (pivot locking ), in which the panel is positioned in an inclined plane relative to the panel plane of the identical other panel and the tongue profile can be locked with its groove profile by subsequently pivoting the inclined panel into the plane of the other panel.
  • Handling can be improved by preparing the groove profile and the tongue profile for swivel locking, wherein a flat lower heel surface is provided on the underside of the tongue, which is aligned parallel to the top of the panel, the groove profile having a support surface for the heel surface of the tongue profile on a lower groove wall, and the support surface is also flat and parallel to the top of the panel.
  • the contact surface provided on the top of the tongue can be designed parallel to the top of the panel and the complementary inner surface of the upper groove wall of the groove profile can be arranged parallel to the top of the panel for this purpose.
  • the contact surface of the top of the spring has a distal end and a proximal end and the heel surface of the bottom of the spring also has a distal end and a proximal end, with a distance expediently being provided between the distal end of the heel surface and the proximal end of the contact surface. (swivel connection)
  • the lower groove wall rises from the plane of the support surface towards the bottom of the groove.
  • the groove profile and the tongue profile are prepared for a snap lock, the tongue profile having a proximal lower shoulder surface on its tongue underside and a supporting surface distally (close to the free end of the spring profile) that the complementary groove profile supports the supporting surface of the tongue profile has a support surface on the lower groove wall, and that the complementary groove profile is provided with a suitable support surface for the lower shoulder surface of the tongue profile.
  • the supporting surface of the tongue profile as well as the associated support surface of the groove profile are expediently arranged parallel to the top of the panel.
  • the support surface is expediently arranged in an area of the lower groove wall which is opposite the upper groove wall. If there is a load on the top of the panel in the area of locked panel edges that exerts pressure on the upper groove wall, then the force is transmitted via the inner surface of the upper groove wall to the contact surface of the top of the tongue and through the tongue profile. On the underside of the spring, the force is transferred from its supporting surface to the supporting surface of the lower groove wall, which in turn transfers the force downwards into a surface on which the panel rests.
  • the support surface provided on the groove profile for the lower shoulder surface of the tongue profile can be arranged in the area of the lower groove wall, which projects further distally from the panel edge compared to the upper groove wall.
  • the support surface provided for the lower shoulder surface of the tongue profile on the groove profile is expediently flat. It can also be designed with a downward inclination in the distal direction.
  • the inclination is preferably in an angular range of 2° - 10° compared to the top of the panel. The inclination is due to the interaction with the design that the lower groove wall has in the area of its free end, as explained in more detail below.
  • the contact surface provided on the top of the spring is conveniently arranged parallel to the top of the panel, with the complementary inner surface of the upper groove wall of the groove profile then also being arranged parallel to the top of the panel, and the inner surface of the upper groove wall being larger than the support surface provided on the lower groove wall.
  • the supporting surface on the underside of the spring is smaller than the contact surface provided on the top of the spring. Therefore, a force introduced from the top of the panel is transmitted from the upper groove wall downwards into the tongue profile via a first pair of surfaces.
  • the first pair of surfaces consists of the inner surface of the upper groove wall and the contact surface of the top of the tongue.
  • the force from the spring profile is then transmitted further downwards by means of a second pair of surfaces consisting of the supporting surface of the underside of the spring and the supporting surface of the lower groove wall.
  • the size of the contact surface of the second pair of surfaces is smaller than the size of the contact surface of the first pair of surfaces.
  • the reduced contact area of the second pair of surfaces is due to the improvement in the strength of the lower groove wall.
  • the center of the inner surface of the upper groove wall is arranged closer to the groove base than the center of the support surface of the lower groove wall. This also serves to improve the strength of the lower groove wall.
  • the groove profile can have a free cut on the inside of the upper groove wall towards its free end, which preferably has an oblique free cut surface.
  • the free cut is expediently prepared in such a way that the width of the groove profile increases towards the free end and forms an enlarged entry opening.
  • the entry opening expanded in this way of the groove profile acts like a funnel for a tongue profile that moves translationally in the direction of the groove profile.
  • the spring profile then first comes into contact with the free cut surface on its spring top.
  • the free end of the spring profile can be designed as a blunt wedge-shaped cross section, with the wedge surface promoting guidance and centering along the oblique cut-out surface of the upper groove wall in order to facilitate the insertion of the spring profile into the groove profile.
  • the wedge surface on the underside of the spring is longer and creates a larger clearance than the wedge surface on the top of the spring.
  • the free cut on the underside of the tongue serves to create space for the lower groove wall, which should be reinforced by making the lower groove wall with an increasing wall thickness towards the groove base.
  • the retaining edge provided at the free end of the lower groove wall is expediently provided with an edge surface which is arranged at a level which makes it possible to slide the underside of the spring of a complementary panel over the edge surface for a snap connection and thereby move the upper side of the spring profile with the free cut on the inside of the upper groove wall.
  • the top of the tongue is supported by the contact on the upper groove wall, which benefits the further joining movement.
  • the tongue profile is moved forward deeper into the groove profile, with the shoulder surface of the tongue profile pressing against the edge surface of the retaining edge of the lower groove wall and the lower groove wall bending elastically downwards towards the underside of the panel.
  • the tongue profile On the top of the tongue, the tongue profile is supported on the inside of the strong upper groove wall.
  • the upper groove wall is due to its smaller distal extent and less forgiving than the bottom groove wall.
  • the wall thickness of the upper groove wall is thicker than the wall thickness of the lower groove wall, which promotes the desired higher rigidity of the upper groove wall compared to the lower groove wall.
  • edge surface is expediently provided with an inclination which is adapted to the inclination of the shoulder surface of the underside of the tongue, or is identical to the inclination of the support surface of the lower groove wall. This ensures that at the beginning of the translational joining movement, the shoulder surface of the underside of the tongue has flat contact with the edge surface and pressure can be exerted evenly on the edge surface in order to begin the elastic bending of the lower groove wall.
  • the underside of the spring can have a concave contour between its supporting surface and its heel surface, with a free space being formed between the concave contour and the lower groove wall when two panels are assembled.
  • the concave contour favors the start of the joining movement. It is known from the prior art that to begin the joining movement, the underside of the spring is initially placed only on the holding edge. It has now been found that the underside of the spring can be so unfavorably inclined that it can slip down there at the very beginning of the joining movement, if it has only been placed on the edge surface of the holding edge. If you have a long panel, it may be difficult to properly place the bottom of the spring on the retaining edge along the entire length of the panel.
  • the concave contour in this area on the underside of the spring makes it easy and safe to place the spring profile on the holding edge and prevent it from slipping off the holding edge.
  • the free space makes it possible for the surface pairing of the support surface/support surface to lie against one another and at the same time for the pairing of the heel surface/support surface to lie flat against one another.
  • the free space also leaves room for particles that can appear anywhere on the lower groove wall. Such particles could disrupt the contact of the aforementioned surface pairings and impair the functionality of the lock.
  • a contact surface pairing consists of the contact surface of the top of the tongue paired with the inner surface of the upper groove wall.
  • At least a second contact surface pairing consists of the shoulder surface of the underside of the tongue paired with the contact surface of the lower groove wall.
  • a third contact surface pairing can consist of the supporting surface of the underside of the spring paired with the supporting surface of the lower groove wall.
  • a slot can be provided below the groove base of the groove profile in the area of the proximal end of the lower groove wall on the underside of the panel, which extends parallel to the panel edge To increase flexibility of the lower groove wall.
  • the slot expediently has a rounded bottom, which reduces notch stresses.
  • the slot may include parallel sidewalls or the slot may have a substantially trapezoidal cross section.
