It is a fastening system for insulation boards made of plastic, with holding profiles are provided on long narrow sides, which can be connected by a rotating joining movement. On the short narrow sides holding profiles are provided with hook elements, which can be positioned so that they overlap and successively during the rotary joining movement for the long narrow sides are joined together. On the short narrow sides, although a good positive horizontal locking of the insulation boards is available. However, a locking of the short narrow sides perpendicular to the laying plane (vertical) is missing.
  • the JP 1219975 relates to a multi-part fastening system in which plate-shaped bottom material has slots on a lower side.
  • a separate rail is provided, which cooperates with the slots of two plates.
  • the rail has holding surfaces for positive horizontal locking, which always have an undercut, which causes a positive locking perpendicular to the laying plane.
  • the WO 00/63510 A1 constitutes a post-published state of the art which is irrelevant to the assessment of inventive step. It provides a fastening system with hook elements, which are to be arranged on short narrow sides of a panel.
  • the hook elements have according to the Figures 7-9 Holding surfaces with two functions. The retaining surfaces cause a positive horizontal as well as a positive vertical locking.
  • a fastening system for panels in particular for floor panels, which are laid on a substrate and whose narrow sides are provided with retaining profiles, the retaining profile of a long narrow side and the holding profile of the opposite narrow side and the holding profiles of the other two short narrow sides of a panel match one another, that further panels are fastened to the free narrow sides of a laid panel, wherein at least the holding profiles of the long narrow sides of the panels formed as mutually associated form-fitting profiles and the panels by a rotating joining movement are fastened to each other, that the positive locking profile of the long narrow sides of a panel a recess and the opposite narrow side of this panel has a mating projection, that the wall facing the base of the recess has on the inside a cross section with a concave curvature and that the z Uordnet positive locking profile of the opposite narrow side of the panel has a projection which has on its underside facing the ground a cross section with a convex curvature, and that the convex curvature of the projection and
  • Fastening systems of this type hold panels together in the finished state by a positive connection. Especially when floating laid on a floor floor panels prevents a positive connection between the panels the emergence of joints that may arise, for example, by thermal expansion or reduction in temperature drop.
  • the known fastening system is only suitable for particularly flat substrates.
  • a panel floor with the known fastening system nestles very poorly on the shape of the irregular ground. If, for example, a panel which in the installed state is held by the adjacent panels with a small amount of air over a corrugated ground is pressed under load onto the ground, then mutually attached floor panels bend through.
  • This deflection claims in particular the joints with the interlocking positive locking profiles.
  • the interconnected panels are bent downwards or upwards and thereby pushed out of the normal laying plane. Due to the high rigidity of the connection, a high load occurs in the weak cross sections of the form-locking profiles, which are thereby damaged very quickly. The damage progresses rapidly until a projection or recess wall breaks.
  • the invention has for its object to improve the stability and durability of known fastening systems.
  • the positive locking profiles of the long narrow sides of two panels can be designed so that they form a common joint in the installed state of two panels.
  • the surface facing away from the surface of the projection of a panel then has an oblique material removal, which extends to the free end of the projection.
  • the thickness of the projection is increasingly reduced by the material removal towards the free end.
  • the removal of material creates a freedom of movement for the common joint.
  • the new design allows articulated movement of two interconnected panels.
  • two interconnected panels at the junction upwards be bent over.
  • the bending forces acting do not damage the narrow cross sections of the form-locking profiles. Instead, a joint movement takes place.
  • a laid with the proposed fastening system floor thus has a compliance adapted to irregular rough or undulating surfaces.
  • the fastening system is therefore particularly well suited for panels for renovating irregular floors in old buildings. Of course, it is also better suited for laying panels on a soft intermediate layer than the known fastening system.
  • the construction takes into account the principle of "adapted deformability". This principle is based on the recognition that very stiff and thus supposedly stable joints cause high notch stresses and thus easily fail. To avoid this, components should be designed so that they have a tailored to the application compliance or "conformable deformability" and thus reduce stress concentrations.
  • the positive locking profiles are designed so that a load on the top of the floor panels in the laid state is transmitted from the top wall of the recess of a first panel in the projection of the second panel and the projection of the second panel in the bottom wall of the first panel.
  • the walls of the recess of the first panel are in an installed state in contact with the top and bottom of the projection of the second panel.
  • the upper wall of the recess has contact with the projection of the second panel only in a short area at the free end of the upper wall of the recess.
  • the construction allows, with little elastic deformation of the walls of the recess, a hinge movement between the panel with the recess and the panel with the projection.
  • the rigidity of the connection is well adapted to an irregular pad, which inevitably leads to a bending movement between panels attached to each other.
  • panels with the fastening system according to the invention are better for a multiple Laying suitable as panels with the known fastening system, because the panels with the fastening system according to the invention even after long use on an irregular surface have no pre-damage of the form-locking profiles.
  • the positive locking profiles are dimensionally stable and durable. They can be used much longer and reused more often during their life cycle.
  • the convex curvature of the projection and the concave curvature of the recess substantially each form a circular section, wherein in the installed state, the circular center of the circular sections on the top of the projection or below the top of the projection is arranged. In the latter case, the circle center lies within the cross section of the projection.
  • the most projecting point of the convex curvature of the projection of a panel is arranged such that it is located approximately below the upper edge of the panel. This results in a relative to the total thickness of the panel relatively strong cross section for the projection.
  • the concave curvature of the recess provides a sufficiently large undercut for the convex curvature of the projection, so that they are hardly moved apart by acting in the laying plane tensile forces.
  • the joint properties of two interconnected panels can be further improved if the wall facing the ground of the recess of a panel on its inside has an oblique material removal, which extends to the free end of the wall and the wall thickness of this wall is increasingly thinner to the free end. In this case, a space for movement of the common joint is created by the removal of material in the laid state of two panels. With this improvement, the proportion of elastic deformation of the walls of the recess during the upward deflection of the laid panels is further reduced.
  • the holding profiles of the short narrow sides of a panel are also formed as mutually associated form-fitting profiles and fastened to each other by a rectilinear joining movement.
  • the retaining profiles of the short narrow side of a panel are simply provided with conventional approximately rectangular tongue and groove cross-sections. These are very simple and inexpensive to produce and can be particularly easy to bring by joining the long narrow sides of a panel by sliding sideways. Also, the long narrow sides of the panels can be pushed into each other along their entire length in a parallel direction. Another development of the short narrow side of a panel provides that the cross sections of the positive locking profiles substantially correspond to the cross sections of the positive locking profiles of the long narrow sides of the panel. The ability to use two panels To join articulated on their short narrow sides, the resilience of a floor covering benefits.
  • the positive locking profiles are integrally formed on the narrow sides of the panels.
  • the panels can be produced very easily and with little waste.
  • the positive-fit profiles according to the invention are particularly suitable if the panels consist essentially of an MDF (Medium Density Fiberboard), HDF (High Density Fiberboard) or particle board material. These materials are easy to process and obtain, for example, by a machining, a sufficient surface quality. In addition, these materials have a high dimensional stability of the milled profiles.
  • MDF Medium Density Fiberboard

  • the freedom of movement for the joint joints is provided with a soft-elastic hardening filler.
  • This filler preferably closes all joints and in particular the top-side joint such that no moisture and no dirt can penetrate.
  • the soft elastic filler is squeezed or stretched depending on the direction of rotation of the joint movement. He always adheres to the contact surfaces of the narrow sides of the panels and takes on the decline of the joint movement back to its original shape. The filler contributes to the recovery of the joint by its elastic inner deformation.
  • An alternative embodiment of the fastening system provides that a short narrow side of a panel has a first hook element and the opposite short narrow side of the panel has a hook element complementary to the first hook element and that the hook elements are provided with retaining surfaces through which the panels in the assembled state against each other are held that results in a gap-free abutting surface of the panels on the short narrow sides.
  • the positive locking profiles of the long narrow sides of the panels must first be joined together.
  • a panel is tilted and inserted with the projection of a long narrow side in the recess of the long narrow side of a laid panel. This forms the common joint.
  • the panel is held in the oblique position and moved in its longitudinal direction until it abuts against the short narrow side of an adjacent panel.
  • the hook elements of the short narrow sides of the adjacent panels overlap.
  • the hook elements fit together. This results in a rear engagement, which locks the panels against pulling in the longitudinal direction.
  • a degree of undercut can be achieved, which is about one third of the total panel thickness.
  • the type of locking the short narrow sides of the panels is reminiscent of laterally engaging behind roof tiles.
  • the first hook element is simply formed from a web which protrudes approximately perpendicularly from the short narrow side and is arranged on the top side of the panel, wherein a hook projection pointing towards the underside of the panel is arranged at the free end of the web and the second hook element protrudes from one protruding from the opposite short narrow side and arranged on the underside of the panel web formed, wherein at the free end of this web a pointing to the top panel hook projection is arranged.
  • the top of the panel goes from the area with the thickness of the complete panel with a thickness graduation into the web.
  • the bridge has about a thickness which is one third of the Panel thickness corresponds. The same goes for the bottom of the panel.
  • the lower-side web extends from the area of the complete thickness of the panel with a thickness graduation into the web, which likewise has approximately one third of the thickness of the panel.
  • the webs and the hook projections are thus formed relatively solid. Therefore, there is an improvement in strength and durability for the fastening system of the invention.
  • the hook projection of the lower-side web is in the mounted state of a panel on the upper-side web of a second panel.
  • air is provided between the hook projection of the upper-side web of the second panel and the lower-side web of the first panel.
  • a development of the fastening system provides that the retaining surfaces of the hook projections engage behind in such a way that they can be hooked into one another only by elastic deformation. In this way it can be prevented that the hook elements can be moved apart, for example because of an uneven ground under load.
  • the connected panel becomes the loaded panel moved in the same direction. The joint stays together.
  • the retaining surfaces of the hook projections are inclined and taper the hook projections from their free ends to the webs out. Furthermore, the holding surfaces of complementary hooks are at least partially adjacent to each other. This is a simple design of the provided with an undercut hook projections, because as an undercut easily manufacturable planar support surface is provided.
  • an air gap between the panels can be tolerated in the joint area.
  • An alternative embodiment with hook elements on the short narrow sides of the panel is constructed so that at least one of the end faces of one of the hook elements of the panels has at its free end a protruding detent element which engages in an undercut depression of the other hook element of the panel.
  • This construction has proven to be particularly easy to handle, because the retaining profiles can be locked together with slight pressure and under elastic deformation.
  • the holding elements have a good wear resistance, which favors a multiple installation. The wear resistance is good because of different locking functions be exercised by different holding element areas and the stress of the holding element occurs so distributed.
  • the panels are locked, for example, by the locking element and the depression perpendicular to the laying plane. The locking of the panels against pulling in the longitudinal direction, however, accomplished by the retaining surfaces of the hook projections.
  • the protruding latching element of the first panel is formed as a bead which extends over the entire length of the narrow side and the undercut recess of the second panel is formed as an elongated throat, which receives the bead in the assembled state.
  • bead and throat must be interlocked under elastic deformation of the hook elements.
  • This embodiment of the fastening system is then, if no gluing is made, especially good for multiple installation.
  • it is expedient first to lift a row of adjacent panels in such a way that they rotate obliquely upwards in the hinge. Then, the projections are pulled in an oblique direction from the recesses and taken apart the joint. The panels are then connected only on the short narrow sides. It is advisable to pull apart the interlocking holding elements of the short narrow sides in their longitudinal extent, in order to avoid material-fatiguing deformation of the hook elements in this way during disassembly.
  • a further improvement is seen in that the areas provided with air in the assembled state of two panels form glue pockets.
  • the proposed attachment system for glue-free installation of floor panels it is particularly well suited for bonding with glue.
  • those parts of the holding profiles which must be provided with glue, for example in an instruction manual or be marked by markings on the holding profile itself. In this way, the user can attach glue there very exactly where resulting in the assembled state of two panels glue bags.
  • the glued laying is considered to be the most convenient method of laying. This is because the durability of the panels is significantly improved.
  • the gluing of the holding profiles has the effect that penetration of dirt and moisture into the joints is almost prevented. The moisture absorption and the swelling of the panels in the joining area of the holding profiles is thereby minimized.
  • the panels are formed from a coated carrier and the holding profiles integrally formed on the narrow sides of the panels.

  • the fastening system 1 is explained using the example of elongate rectangular panels 2 and 3, of which in Fig. 1 a section is shown.
  • the fastening system 1 has arranged on the narrow sides of the panels holding profiles, which are formed as complementary positive locking profiles 4 and 5.
  • the opposite positive locking profiles of a panel are each formed complementary. In this way, a further panel 3 can be attached to each already laid panel 2.
  • the positive locking profiles 4 and 5 are based on the prior art of the German utility model G 79 28 703 U1. In particular, on the form-locking profiles of the embodiment, which is disclosed in Figures 14, 15 and 16 and in the associated description part of G 79 28 703 U1.
  • the positive locking profiles according to the invention are developed such that they allow an articulated and resilient connection of panels.
  • One of the positive locking profiles 4 of the present invention is provided with a projecting from the narrow side projection 6.
  • the underside of the projection 6, which faces in the installed state of the pad, has for the purpose of articulated connection a cross section with a convex curvature 7 on.

  • the arranged below the projection 6 part 8 of the narrow side of the panel 3, which faces in the installed state of the base, is further from the free end of the projection 6 than the above the projection 6 arranged part 9 of the narrow side.
  • the portion 8 of the narrow side arranged below the projection 6 recedes approximately twice as far from the free end of the projection 6 as the portion 9 of the narrow side arranged above the projection 6. This is due to the fact that the circular portion of the convex curvature 7 is formed relatively wide. As a result, the most projecting point of the convex curvature 7 of the projection 6 is arranged so that it is located approximately below the upper edge 10 of the panel 3.
  • the part 9 of the narrow side which is arranged above the projection 6, protrudes from the narrow side on the upper side of the panel 3 and forms a joint abutment surface 9a. Between this joint abutment surface 9a and the projection 6 of the panel 3, the part 9 of the narrow side is reset. This ensures that the part 9 of the narrow side always forms a closed top-side joint with the complementary narrow side of another panel 2.
  • the convex curvature 7 of the projection 6 opposite upper side of the projection 6 has a short straight portion 11, which is also arranged parallel to the substrate U in the installed state.
