Definitions

  • the invention relates to a floor covering, a panel and a fastening system for panels with on the narrow sides of the Panels arranged holding profiles, especially for floor panels, opposing holding profiles as complementary Form-fit profiles are formed.

  • Fastening systems of the type mentioned keep panels ready installed condition by a positive connection. Especially when laid floating on a surface Floor panels prevent a positive connection between the panels the creation of joints, for example through thermal expansion or shortening when the temperature drops can arise.
  • the known fastening system is disadvantageously suitable only for particularly flat surfaces. With irregular, rough and corrugated surfaces nestle with a panel floor the known fastening system only very poorly in shape of the irregular surface. For example, if a panel, that when laid through the neighboring panels with some air over a corrugated surface Load pressed on the surface, so bend together paved floor panels. This deflection claims especially the connection points with the interlocking ones Form-fitting profiles. Depending on the load, the interconnected panels bent down or up and pushed out of the normal installation level. Because of the high rigidity of the connection, a high load occurs in the weak cross sections of the positive locking profiles which can be damaged very quickly. The injury progresses quickly to a ledge or a recess wall breaks.
  • the invention is therefore based on the object, the known To further develop the fastening system so that the rigidity of the Connection of two interlocking positive locking profiles to the Strain is adjusted to the connections when laying the panels have to endure on an irregular surface.
  • the object is achieved in that Positive locking profiles an articulated and flexible connection the panels is possible.
  • the form-fitting profiles of the long narrow sides of two panels form a joint in the installed state of two panels.
  • the top of the projection facing away from the ground of a panel preferably has an oblique material removal that extends to the free end of the projection.
  • the thickness of the projection is favorable due to the material removal increasingly reduced towards the free end. Through the Material removal is a freedom of movement for the common Joint created.
  • the new construction allows articulated movement of two interconnected panels.
  • two can work together connected panels at the connection point upwards be buckled.
  • a panel is on top of one Underground with an elevation so that a narrow side of the panel is pressed onto the surface when loaded and - the opposite narrow side bounces upwards, so one second panel attached to the upward rocking narrow side moved up with.
  • a floor laid with the proposed fastening system shows an irregular rough or wavy surface adjusted compliance.
  • the fastening system is therefore particularly suitable for panels for renovation irregular Floors in old buildings. Of course it is also for laying panels on a soft intermediate layer more suitable than the known fastening system.
  • the construction is based on the principle of "adapted deformability" Bill. This principle is based on the knowledge that very stiff and therefore supposedly stable connection points cause high notch stresses and therefore easily fail. Around To avoid this, components should be designed so that they a compliance or "adapted to the intended use Have deformability "and in this way notch stresses can be reduced.
  • the positive locking profiles are designed so that a load on the top of the floor panels in the installed Condition of the top wall of the recess of a first Panels in the projection of the second panel and from the projection of the second panel in the underside wall of the first Panels is transferred.
  • the walls of the recess of the first When installed, panels have contact with the top and Bottom of the protrusion of the second panel.
  • the recess has only a short area on the free end of the top wall of the recess contacting the protrusion of the second panel. In this way, the construction allows with little elastic deformation of the walls of the Recess a joint movement between the panel with the recess and the panel with the tab. That way the rigidity of the connection is perfectly adapted to an irregular one Underlay, which inevitably leads to a kinking movement between panels fastened together.
  • the convex curvature of the projection and the concave curvature of the cutout essentially a segment of a circle, where in the installed state the center of the circle Circular sections on the top of the tab or below the top of the projection is arranged. In the latter case the center of the circle lies within the cross-section of the projection.
  • the joint properties of two interconnected panels can be further improved if the one facing the underground Wall of the recess of a panel on the inside has an oblique material removal that extends up to the free End of the wall extends and the wall thickness of this wall to free end is increasingly thinner. This is due to material removal When two panels are installed, there is freedom of movement created for the common joint. With this improvement is the proportion of elastic deformation of the walls the recess during the deflection of the installed panels further decreased upwards.
  • the holding profiles of the short narrow side are simply one Panels with conventional approximately rectangular tongue and groove cross-sections Mistake. These are very simple and inexpensive producible and can be added after joining the long Narrow sides of a panel are particularly easy thanks to the side Move into one another. Even the long ones Narrow sides of the panels along their entire length in parallel Slide towards each other.
  • the form-fitting profiles are preferably in one piece on the narrow sides molded on the panels.
  • the panels can be very easily and produce with little waste.
  • the form-fitting profiles according to the invention are particularly suitable, if the panels are essentially made of MDF (Medium Density Fiberboard), HDF (High Density Fiberboard) or one Chipboard material exist. These materials are just too process and receive, for example by machining, adequate surface quality. Also point these materials have a high dimensional stability of the milled Profiles on.

  • Chipboard material are just too process and receive, for example by machining, adequate surface quality. Also point these materials have a high dimensional stability of the milled Profiles on.
  • An alternative design of the fastening system provides that a short narrow side of a panel is a first hook element and the opposite short narrow side of the panel has a complementary hook element to the first hook element and that the hook elements are provided with holding surfaces are through which the panels against each other in the assembled state are kept on the short narrow sides results in a gap-free abutting surface of the panels.
  • the form-fitting profiles must first be used the long narrow sides of the panels. For this, a panel is placed at an angle and with the projection a long narrow side in the recess of the long narrow side of a laid panel. This is how it forms common joint. After that, the panel will be in the oblique position held and shifted so far in its longitudinal direction, until it hits the short narrow side of an adjacent panel encounters. In this position the hook elements of the overlap short narrow sides of the adjacent panels. If so slanted panel folded down using the hinge the overlapping hook elements fit into each other. It there is a grip behind, which prevents the panels from pulling apart locked in the longitudinal direction. Through the hook elements a degree of undercut is achievable that at is about a third of the total panel thickness.
  • the kind of Locking the short narrow sides of the panels is a reminder roof tiles that reach behind on the side.
  • the first hook element is simply one of the short narrow side protruding approximately vertically and on the Panel top arranged web formed, being on the free At the end of the web a hook projection pointing towards the underside of the panel is arranged and the second hook element from one protruding from the short opposite side and a web arranged on the underside of the panel, at the free end of this web one towards the top of the panel pointing hook projection is arranged.
  • the top of the panel goes from the area with the thickness of the complete panel with a thickness gradation across in Web.
  • the web has a thickness that is about a third of that Corresponds to panel thickness.
  • the same goes for the bottom of the Panel.
  • the webs and the hook projections are therefore relatively solid educated. Therefore, there is an improvement in strength and durability for the fastening system according to the invention.
  • the hook projection of the underside web is advantageously in the assembled state of a panel on the top web of a second panel. It is also between the hook projection of the upper web of the second panel and the lower one Web of the first panel air is provided.
  • a further development of the fastening system provides that the Reach behind the retaining surfaces of the hook projections that they can only be hooked into one another by elastic deformation are. In this way, the hook elements can be prevented for example because of an uneven surface Load can be moved apart. With a load one panel becomes the connected panel with the loaded panel moved in the same direction. The joint remains together.

  • An alternative embodiment with hook elements on the short Narrow sides of the panel is designed 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 locking element that in an undercut recess of the other hook element of the panel.
  • This construction has proven special well manageable because the holding profiles with light pressure and lock into place under elastic deformation to let.
  • the holding elements have good wear resistance on what favors multiple laying. The wear resistance is good because different locking functions exercised by different holding element areas are distributed and the stress on the holding element occurs.
  • the panels are, for example, by the locking element and the recess is locked perpendicular to the installation plane. The Locking the panels against pulling apart in their longitudinal direction is, however, by the holding surfaces of the hook projections accomplished.
  • the protruding locking element of the first panel is simply formed as a bead that extends over the entire length the narrow side extends and the undercut recess of the second panel is formed as an elongated throat, which takes up the bead in the assembled state.
