Definitions
- the invention relates to a panel with a panel core, a top side of a panel, a bottom side of a panel and a first pair of edges and a second pair of edges, the first pair of edges being provided with a groove profile on one panel edge and a tongue profile complementary thereto on the opposite panel edge, which a pivoting movement can be locked and then interact in a form-fitting manner in such a way that a vertical locking effect can be achieved in the locked state and a moving apart of locked panels in the plane of the panels (horizontally) is counteracted, the second pair of edges being provided with complementary hook profiles on their opposite panel edges, namely a receiving hook and a locking hook, wherein the locking hook can be assembled simultaneously with the receiving hook by a joining movement in a plane perpendicular to the panel plane by means of the pivoting movement for the first pair of edges, with de r Provided that the receiving hook is provided with a retaining groove for a separate locking element with which a vertical locking effect can be achieved.
- a generic panel is known from EP 1 415 056 B1. It is a panel that has a first pair of edges with a tongue and groove profile and a second pair of edges with hook profiles included. As a result, the known panel can be locked to the groove profile of the panels of a previous row of panels by means of a pivoting movement at an edge with a tongue profile. It is seen as a great advantage that one of the edges with a hooked profile is also locked at the same time by means of the pivoting movement mentioned.
- the separate blocking element snaps into place by itself. The latching function of the blocking element is automatically triggered by the aforementioned pivoting movement on the first pair of edges of the panel.
- This type of laying is also referred to as fold-down laying or the appropriate panel as fold-down panel.
- Such panels are connected to one another in rows, resulting in transverse joints between the panels within a row of panels.
- longitudinal joints are formed between the rows of panels of a covering surface formed in this way as a composite. It is desirable that the longitudinal and transverse joints of such a covering surface should have a certain impermeability against water running through.
- water can penetrate into joints and in places run through the joint from the top of the panel to the bottom of the panel. Water penetrating or passing through in this way can lead to the formation of mould, which can spread hidden under a floor covering surface. It has been shown that moisture can penetrate or penetrate in particular via the transverse edge and the crossing points of the transverse and longitudinal edges. can go through .
- the invention has for its object to propose a panel that has an improved design at least Profiles of the second pair of edges to better counteract the passage of water at the joints.
- an abutment surface is arranged essentially orthogonally on the receiving hook relative to the top side of the panel
- a counter-abutment surface is arranged essentially orthogonally relative to the top side of the panel on the locking hook, that the counter-joint is arranged on the second pair of edges at a lower end
- a sealing lug is provided on the surface of the locking hook or on a lower end of the abutment surface of the receiving hook, which extends parallel to the respective panel edge over the entire length of the counter-abutment surface or the abutment surface.
- the sealing lug projects at the panel edge in a distal direction from the abutment surface of the receiving hook or in a distal direction from the counter abutment surface of the locking hook.
- the cross section of the sealing lug expediently has an outer contour composed of rounded and/or curved sections.
- a distal end of the curved or rounded sealing nose has an inflection point, or an inflection point tangent.
- the turning point tangent is arranged at an angle of between >30° and ⁇ 90°, preferably >45° and ⁇ 90°, in particular >60° and ⁇ 90°, relative to the top side of the panel.
- the inflection point tangent is preferably applied in the inflection point distally at the maximum distance from the panel core.
- the proposed panel is provided with a sealing measure that is spatially physically arranged in the area below the deepened joint and above the point of action for the vertical locking effect.
- the sealing lug provided on the counter-impact surface acts in the locked state together with the impact surface sealing effect achieved.
- the seal can be achieved by pressing the sealing lug against the abutting surface and/or by swelling of the sealing lug in the presence of moisture, because it is then enlarged by the swelling process and comes into sealing contact with the abutting surface.
- a further measure that contributes to sealing can be achieved if at least one of the pairs of edges has a broken edge on its two complementary panel edges, which forms a deepened joint when two of these panels are joined together.
- edge breaks of at least one of the edge pairs of the complementary panel edges are expediently provided with a larger edge break and a smaller edge break, with the larger edge break being covered by the smaller edge break in the assembled state.
- the cross section of the retaining groove for the separate blocking element can simply be retained and a known blocking element can be used. Suitable blocking elements are known, for example, from EP 1 415 056 B1, WO 2011/087425 A1, US Pat. No. 9,347,469 B2 or US Pat. No. 7,866,110 B2. Reference is hereby made to the design examples for separate blocking elements and their arrangement on a panel, as defined in the aforementioned publications, and this technical teaching is included.
- the separate locking element for the complementary hook profiles can optionally be provided as part of the panel. It is then preferably preassembled in the retaining groove of the receiving hook.
- the proposed panel has a square basic shape on .
- the tongue profile of the first pair of edges meets the hook of the second pair of edges at one of the four corners of the panel. These two different shapes of the panel edges intersect in this corner, creating an intersection zone of the different profile shapes, resulting in a complex three-dimensional shape.
- the complex shape is due to the fact that the receiving hook must have the retaining groove for the locking element and that therefore this retaining groove at the corner meets the tongue profile of the adjacent panel edge of this corner.
- material from the panel core must be removed, for example milled. The milling of the retaining groove runs through the tongue profile at one end (transition zone) and cuts part of the panel core that formed the tongue. A part of the material of the spring profile is thus machined and removed.
- the complementary hook profiles of the second pair of edges namely the receiving hook open at the top and the locking hook open at the bottom, advantageously have retaining surfaces provided on both sides in one piece on the panel core, by means of which the locking effect prevents the panels from moving apart within the panel plane away from one another in a vertical direction to the interlocked panel edges is achievable.
- the locking effect in the perpendicular to The vertical direction lying on the top of the panel is particularly user-friendly and easily accessible by means of the separate locking element.
- the carrier plate on which a panel according to the invention is based has a fiber material, such as a high-density fiber material (HDF) or a medium-density fiber material (MDF), a coarse chipboard material
- a fiber material such as a high-density fiber material (HDF) or a medium-density fiber material (MDF), a coarse chipboard material
- the panel can also be made for the panel to have a decoration, with this decoration being formed either by applying a decorative layer that has already been printed onto a carrier plate or by directly printing the carrier plate with such a decoration.
- direct printing is also to be understood as meaning printing on a printing substrate that has previously been applied to a carrier plate.
- the panel consists of a solid wood material or is formed entirely from a wood material.
- such a fiber material can absorb water or liquid in the event of contact with moisture, which leads to swelling. Such swelling leads to an improved sealing closure in the area of the sealing lug or the abutment surface and the counter-abutment surface.
- the carrier plate on which a panel according to the invention is based comprises a plastic material, such as a polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), an acrylonitrile-butadiene-styrene copolymer (ABS), a polyvinyl chloride (PVC), a polycarbonate
- a plastic material such as a polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), an acrylonitrile-butadiene-styrene copolymer (ABS), a polyvinyl chloride (PVC), a polycarbonate
- PC polyamide
- PA polyetherketone
- PEEK polyetheretherketone
- an improvement in the tightness can be achieved by providing a projection on the panel edge with the smaller edge refraction, on the upper side of which at least part of the smaller edge refraction extends, and that on an underside of the projection an undercut counter surface for the covered part of the larger edge breaking is provided.
- the smaller chamfer of the first pair of edges is arranged on the groove profile and the larger chamfer on the tongue profile and that the smaller chamfer of the second pair of chamfers is arranged on the locking hook and the larger chamfer on the receiving hook.
- the abutment surface on the hook below the large broken edge is arranged orthogonally relative to the top side of the panel, with the counter-abutment surface provided on the locking hook being at an angle in the range of l relative to the orthogonal on the top side of the panel ° -5 ° inclined , and that the cross section of the locking hook in the inclined area of the abutment surface has an oversize , so that in the locked state a pressure can be brought about between the abutment surface and the abutment surface .
- oversize refers to the ratio of the two joinable panel edges.
- oversize means that there is more material on either the butt surface and/or the counter butt surface based on the nominal size is such that the surface of the abutment surface and/or the surface of the counter-abutment surface protrudes further distally than that nominal size .
- it can be a hundredth to a few tenths of a millimeter maximum oversize, which in practice causes the desired pressure between the abutting surface and the counter-abutting surface of the joined panel edges.
- This desired pressure is expedient in the upper area of the impact surface and the counter-impact surface and can, for. B. extend over half the height of the impact area or counter-impact area.
- An advantageous development provides that the pressure between the counter-abutment surface and the abutment surface is greater at the upper end of the abutment surface and decreases towards the lower end of the abutment surface.
- the benefit can be further improved if the sealing lug is arranged at the lower end of the pressure between the counter-abutment surface and the abutment surface, with which increased pressure against the abutment surface can be generated in the locked state.
- the separate blocking element has a snap-in means with which it can be automatically snapped into a snap-in recess in the complementary panel edge.
- An alternative provides that the holding groove for the separate blocking element has parallel groove walls.
- the groove walls of the retaining groove are expediently at a constant distance from one another.
- the retaining groove or the groove walls of the retaining groove are arranged inclined relative to the top side of the panel.
