Abstract

The invention relates to a panel element (1) having an element surface (1a) and having at least two mutually opposite element edges (2, 3) which are provided with positive locking profiles (4, 5), wherein the positive locking profile of an element edge (2) Type A corresponds and is compatible with panels of type A, and that the positive locking profile of the opposite element edge (3) corresponds to a type B which is compatible with panels of a type B.

Description

  • The invention relates to a panel element with an element surface and at least two opposing element edges, which are provided with positive locking profiles.
  • Basically, it concerns the technical field of positively connectable panels, which are preferably used for the production of coverings on building ceilings, building walls and in particular building floors application.
  • Form-fitting connectable panels for building surfaces are made of different materials and in different panel thicknesses. In addition, there are many types of positive panel edges that are not compatible with each other Therefore, to create a building surface always several identical or mutually compatible panels must be connected to a covering surface. The panels, in turn, have at opposite panel edges such locking profiles that are designed to be complementary to each other. If a panel cut through parallel to the locking profiles in two parts, then the two parts can be positioned reversed and the complementary locking profiles are positively connected with each other. In practice, panels are sawn through at the end of a panel row to shorten the last panel in the row to the required length. The remaining one The rest of the panel can usually be used to start a new row of panels.
  • A flooring surface is made up of panels with similar panel edges or panel edges that are compatible with each other.
  • Such panels are intended to disguise or occupy a building surface as effectively as possible. Therefore, panels have a length and width that is many times the panel thickness. In most cases, the panels have a width which is at least ten times the thickness and the length is considerably longer than the width.
  • With the panel element proposed here is not intended to occupy large parts of a building surface.
  • Rather, the panel element is designed so that the positive locking profile of one element edge corresponds to type A and is compatible with panels of type A, and that the positive locking profile of the opposite element edge corresponds to type B which is compatible with type B panels.
  • In this case, the panels of one type (A or B) on opposite panel edges always positive locking profiles that are complementary to each other. From panels of the same type each surface building coverings can be built by the panels are positively connected with each other.
  • The proposed panel element is able to act as a coupling or adapter element between panels with different panel edges. So a building covering can be made of panels that are not compatible with each other.
  • As a rule, panels are laid in rows. To within To change a building surface from a first panel type to a second type of panel that is incompatible with the first type of panel, simply attach a row of panel elements according to the invention to the begun building panel of first type panels. Panels of the second panel type, which is compatible with the free element edge of the panel elements of the row, can then be attached to this series of panel elements.
  • Without the series of panel elements with adapter function, the panels of the second panel type could not be directly connected to the panels of the first type.
  • The panel element expediently has an extension (width) from one element edge to the opposite element edge, which is smaller than ten times the panel thickness, preferably smaller than seven times the panel thickness and particularly preferably smaller than five times the panel thickness. Panel elements arranged in a row thus visually set themselves apart from the wider panels.
  • Because the panel element is designed as an adapter element that acts as a connecting element between different panel types, it does not itself have any major function in covering the building surface. The covering function should essentially be fulfilled by those panels which can be coupled to its two element edges. Although the connecting panel element or the connecting row of panel elements also covers a smaller area of the building surface, which as a rule can be kept small, however.
  • Of course, the panel element according to the invention may alternatively have the same width as a conventional panel or even wider than this. If it has an identical width as a conventional panel, then it is almost indistinguishable within a building covering from usual panels. A distinction is then possible - if desired - based on the design of its surface.
  • In a further alternative, the minimum distance between the opposing element edges corresponds to at least half the panel thickness of the panel element at the element surface.
  • One of the element edges may have a locking profile identical to one of the locking profiles shown in FIG DE 20 2014 010 455 referred to as holding profile and there based on the embodiments of FIGS. 1a to 15b are explained by way of example.
  • Furthermore, one of the element edges may have a locking profile which corresponds to one of the locking profiles, which in the DE 202 20 655 U1 as a groove profile, referungswiese referred to as a spring profile and there on the basis of the embodiments of FIGS. 1 to 4 are explained by way of example.
  • The panel element may moreover have geometries at its opposite element edges, as known, for example, from the following publications: WO 97/47834 A1 . EP 1 462 587 A1 . WO 00/066856 A1 . WO 01/02670 A1 . WO 03/016654 A1 and European application no. 14196822 , wherein in each case geometries are selected for the opposite element edges of the panel element, which are incompatible relative to each other.
  • Suitably, at least one of the locking profiles of the opposite element edges is designed as a form-fitting, undercut locking groove and / or at least one of the locking profiles as a positive, undercut locking spring.
  • Alternatively, at least one of the locking profiles as lower hook element and / or at least one of the locking profiles designed as an upper hook element.
  • The element surface may be provided with an edge refraction at least at the edge of one of the element edges, which have the locking profiles.
  • The panel element may be provided with a second pair of locking profiles on its opposite end faces. The arranged on the end faces locking profiles of the panel element are complementary to each other. In this way, the panel elements can be connected together in a row next to each other at the frontal joints. A simple design of the locking profiles for the front sides has conventional tongue / groove, which are pushed only laterally into each other. With this simple design, no undercut can be overcome on this straight joining path. Tongue and groove can be glued.
  • Panel elements according to the invention can be designed with different decorative surfaces. They can be designed and adapted to blend well with decors-compatible panels.
  • The invention is illustrated by way of example in a drawing and described in detail with reference to several embodiments. Show it:

  • The locking profiles 4 and 5 preferably interact positively with compatible locking profiles of the corresponding panels.
  • In principle, it is also conceivable to provide an element edge 2 or 3 with a conventional groove or a conventional spring, which could be connected by means of adhesive. Because they would not be secured by a positive fit against a moving apart in the panel plane and perpendicular to the connected element edges, this function could be met by means of an adhesive bond.
  • All combinations shown here of two locking profiles on opposite element edges can be combined in various ways; Many combinations are possible, which should not be shown here. The only criterion is that the opposite locking profiles of a panel element are not compatible with the same type of panel, but always different types of panels are coupled.
