Definitions

  • the invention relates to a floor covering with at least two flat floor covering elements, each of which has a usable surface and can be laid on a substrate with a bearing surface opposite the usable surface, and with at least one connecting element with which the two floor covering elements laid adjacent to one another are connected to one another, with each Floor covering element has at least one recess in the support surface, which extends away from the side surface, starting from a side surface of the floor covering element connecting the usable surface to the support surface, wherein the at least one recess in the floor covering element each has an anchoring area and a connection area connecting the anchoring area to the side surface , wherein the anchoring area has at least one undercut surface that extends laterally beyond it relative to the connection area, wherein in the two floor covering elements laid adjacent to one another, at least one recess of the first floor covering element is arranged with the connection area flush with the connection area of an associated recess of the second floor covering element, wherein the at least one connecting element from the respective bearing surface of the first and second floor covering element in the
  • floor coverings Numerous different floor coverings are known from practice, in which several flat floor covering elements are arranged adjacent to one another on a substructure or on a floor covering substructure erected on the substructure and cover the substructure.
  • the individual floor covering elements can each be fixed independently of one another to the subsurface or a corresponding substructure, for example by gluing the individual floor covering elements to the subsurface with a suitable adhesive.
  • a loose arrangement of the individual floor covering elements on the subsurface which is also referred to as floating installation of the floor covering elements, can be easily removed from the subsurface again at a given time and, for example, exchanged or replaced with another floor covering.
  • the composite effect of the floor covering elements connected to one another can reliably prevent undesired slipping of individual floor covering elements and thereby also avoid gaps or gaps occurring between adjacent floor covering elements during the intended use of the floor covering, through which gaps or gaps arise, through which an intended use of the floor covering as well as its overall aesthetic impression can be affected.
  • a reliable connection of adjacent individual floor covering elements is often not only advantageous, but also necessary in order to produce a sufficiently resilient floor covering with the help of the composite effect, in which individual floor covering elements do not move unintentionally during the intended use of the floor covering.
  • a reliable connection of the adjacent floor covering elements is of particularly great importance, since the individual floor covering elements are joined together to form the floor covering exclusively due to the composite effect caused by the respective connection of the adjacent floor covering elements and are retained as a composite on the subsoil.
  • the connection of adjacent floor covering elements takes place by forming a tongue and groove connection.
  • the tongue and groove connection is a tongue that projects laterally on a side surface of a first floor covering element and is usually in the form of a strip and is inserted into a groove that is adapted thereto and is formed on an associated side surface of a second floor covering element.
  • the tongue-and-groove connection is form-fitting perpendicular to the subsurface and causes a non-positive or clamping connection of the adjacent floor covering elements in a plane parallel to the subsurface.
  • Tongue and groove connections are also known in which a form-fitting engagement of the tongue element with the groove of the adjoining floor covering element adapted to it can also be brought about in a direction running parallel to the subsurface with undercuts through a suitable shaping of the tongue element and the groove adapted thereto .
  • the individual floor covering elements and in particular the tongue and groove connections required for connecting the adjacent floor covering elements can be produced with sufficient precision and with low manufacturing tolerances, so that even a large floor covering can be produced from the individual floor coverings essentially free of gaps and joints
  • Floor covering elements can be joined together.
  • the composite effect produced with such tongue and groove connections also has disadvantages. For example, it is not possible to easily detach an individual floor covering element that is not located at the edge of the floor covering from the composite of the individual floor covering elements in order to repair or replace it, for example. Even at For most of the floor covering elements located at the edge, it is not possible to detach the relevant floor covering element or it is only possible by damaging a laterally arranged tongue and groove connection. Especially with a complex shape of the tongue and groove connection, the assembly of individual floor covering elements is also found to be tedious and time-consuming.
  • connecting elements for floor covering elements laid next to one another are shown and described, the connecting elements engaging into the individual floor covering elements from an underside and two adjacently arranged floor covering elements being able to be connected to one another with a connecting element.
  • Connecting elements shown are designed as joint elements, which have laterally projecting engagement elements, which in turn engage in recesses on the underside of the floor covering elements. If the floor covering is to be laid in such a way that no joint elements are visible, as is the case with parquet flooring, for example, the in GB 1 350 754 A described fasteners are not used.
  • connecting elements are shown and described in each case, which are not visible from a visible or useful side of the floor covering elements and engage in correspondingly adapted recesses from the underside of the floor covering elements.
  • the arrangement and assembly of the connecting elements and the floor covering elements engaging therein and connected to one another via the connecting elements is comparatively complex and requires in particular a completely flat and hard surface, since otherwise the individual connecting elements cannot or not fully be pressed into the recesses on the underside of the floor covering elements and no reliable connection of adjacently laid floor covering elements can be effected.
  • a pressure plate projecting laterally beyond the underside of the connecting element is arranged on an underside of the connecting element facing the bearing surface of the floor covering elements.
  • the floor covering according to the invention can also be laid on a soft or elastic substrate, such as footfall sound insulation or on an old carpet.
  • a connecting element does not fall into the during the assembly of adjacent floor covering elements associated recess is pressed, but is pressed by the floor covering elements in the flexible subsoil, whereby a quick and reliable laying of the floor covering is made more difficult.
  • a pressure plate is provided according to the invention that projects laterally beyond the underside of the connecting element.
  • the pressure plate should expediently have a sufficiently large base area so that the pressure plate cannot simply be pressed into the flexible subsoil, but rests on a surface of the flexible subsoil and presses the connecting element fixed thereon into the recesses in the associated floor covering elements.
  • the pressure plate can have, for example, a circular, an oval or a rectangular cross-sectional area parallel to the bearing surface of the floor covering elements.
  • the pressure plate can have a thickness of, for example, one millimeter. It is also possible for the thickness of the pressure plate to be smaller, for example only 0.5 mm, or larger, for example 1.5 mm or 2 mm or even more.
  • the connecting element connects two adjacent floor covering elements by the form-fitting engagement of the respective end area or anchoring section in the associated anchoring area of the two floor covering elements connected thereby.
  • the connecting element is pushed from the bearing surface opposite the usable surface into the recesses of the two, which are arranged in alignment with one another adjacent floor covering elements and is therefore not visible from the usable surface. Due to the respective positive engagement of the connecting element in the two recesses of the adjacent floor covering elements, the two floor covering elements are reliably fixed to one another and connected to one another in a form-fitting manner.
  • a reliable and resilient composite effect can also be produced with comparatively small connecting elements.
  • a complex tongue and groove connection that regularly extends over the entire length of the floor covering elements and that also causes only a clamping and not a form-fitting connection is not required.
  • the two adjacent floor covering elements do not have to be shifted parallel to the ground in order to be able to connect the two floor covering elements with the connecting element. Rather, it is possible in a simple manner to move one of the two floor covering elements perpendicularly to the subsoil and thus parallel to the side surface of the floor covering element in question onto or away from the subsoil and thereby to connect it to the connecting element and the adjacent floor covering element or to detach it from it . As a result, it is easily possible to detach a single floor covering element or several floor covering elements from the composite effected with the respective connecting elements from a floor covering assembled from numerous floor covering elements and to remove them from the floor covering without the adjacent floor covering elements also having to be separated from the composite effect. Both laying and subsequent replacement of individual ones Floor covering elements is possible in a simple manner and without a special tool.
  • the connecting area of the recess in the floor covering elements can be, for example, a channel running in a straight line, or a groove extending from the bearing surface into the floor covering element.
  • the anchoring area can, for example, extend deeper into the floor covering element or extend laterally further than the connecting area in at least one direction.
  • the anchoring area can be, for example, a cuboid or hemispherical depression, the dimensions of which have a larger clear width than the connecting area, particularly in a transition area to the connecting area, so that the anchoring area, which is preferably designed to be larger, in the transition area from the connecting area to the anchoring area means that a undercut surface extending beyond the connection area is formed.
  • connection area of the recess is only comparatively short and extends from the side surface of the floor covering element to the anchoring area which is only slightly spaced from the side surface of the floor covering element.
  • the connection area in the recess essentially serves to make the anchoring area accessible from the side surface, so that the connection element engages in two adjoining recesses of the adjacently arranged floor covering elements and the two Anchoring areas can connect to each other.
  • the anchoring areas can therefore also reach up to the respective side surface, so that the connection area essentially consists of an opening in the side wall, which allows the anchoring area to be accessible from the outside.
  • the recess could be formed by a circular blind hole, the base area of which is arranged to a major extent within the floor covering, so that the side wall intersects the base area of the blind hole.
  • the portion of the blind hole drilled from the support surface that is located in the floor covering element then corresponds to the anchoring area, while the lateral opening of the blind hole in the side surface of the floor covering element corresponds to the connection area of the recess.
  • the undercut surface may be oriented at an angle to an inner wall of the connection area of the recess. It is also possible that the connection area widens gradually and merges continuously into the anchoring area, so that the undercut surface can be designed as a section of the inner wall of the recess in which the clear width of the recess increases starting from the connection area.
  • the connecting element has in each of the two anchoring sections an undercut surface adapted to this and with the Undercut surface form-fitting engaging formation.
  • the formation can be, for example, a formation that protrudes laterally or from the support surface toward the usable surface, such as a latching lug or a latching hook.
  • the formation can also be a suitably designed thickening or widening of the end area, which is adapted to a shape of the anchoring area of the recess and is designed larger than the connecting area of the recess, so that the connecting element with the thickening or widening at the end area can be introduced into the anchoring area of the recess and fixed therein.
  • the connecting element may have a plurality of laterally protruding latching lugs or latching lamellae in one or both anchoring sections, which may engage with a plurality of undercut surfaces extending laterally beyond the connecting region of the recess.
  • the connecting element and the recesses in the adjoining floor covering elements are suitably matched to one another such that the two adjoining floor covering elements are pressed tightly against one another with the connecting element and thus without gaps and are connected to one another.
  • the connecting element can optionally be made of an elastic material and the distance between the two anchoring sections of the connecting element can be slightly smaller than the distance between the two anchoring areas of the associated recesses in the adjacent floor covering elements, so that the connecting element undergoes a certain deformation when it is introduced into the two recesses and as a result a force effect is generated which presses the two floor covering elements against one another.
  • each floor covering element has side surfaces designed without undercuts along the side edges.
  • the floor covering element can have, for example, a square or rectangular bearing surface and an identically designed usable surface.
  • the side edges then each extend perpendicularly from the bearing surface, projecting from the bearing surface to the usable surface.
  • Side surfaces designed without undercuts can ensure that each floor covering element can be detached from the floor covering and consequently also from the connecting elements initially still engaged with the floor covering element by moving the side surfaces designed without undercuts relative to the adjoining side surfaces of the adjoining floor covering elements.
  • the individual connecting elements do not have to be accessible for a floor covering element to be pulled out in this way.
  • the connecting element is arranged completely within the two mutually associated recesses of the first and second floor covering element.
  • the connecting element can fill the two recesses completely or have a smaller volume than the two recesses and optionally be arranged and fixed in the recesses at a distance from the bearing surface of the floor covering elements.
  • the connecting elements are therefore either arranged flush with the surface or offset inwards in the recesses of the floor covering elements and in any case do not protrude beyond the bearing surface. The laying of the floor covering elements on the ground is therefore not affected by the connecting elements.
  • each anchoring section of a connecting element has at least one engagement element, which is designed to project laterally over the connecting section in the direction of the working surface and/or parallel to the side surface.
  • a form-fitting engagement of the engagement element with the anchoring area in the recess can be effected in a simple manner by an engagement element projecting at least in one direction beyond the connecting section.
  • the engagement element can, for example, only protrude in the direction of the working surface over the connecting section, or only laterally parallel to the side face over the connecting section.
  • the engagement element projects over the connecting section both in the direction of the working surface and parallel to the side surface in both lateral directions.
  • the engagement element can be, for example, a latching element already mentioned above or a laterally projecting formation.
  • the engagement element can also be formed by a thickened or widened end area of the connecting element.
  • everyone Anchoring section can also optionally have several engagement elements, each of which abuts and can engage with the same undercut surface, or engage with several undercut surfaces, which are formed in the transition area from the connecting area to the anchoring area in the recesses.
  • each anchoring section of a connecting element has at least two engagement elements which are resiliently fixed to the connecting section and are clamped in the anchoring section of the associated recess.
  • the resiliently designed engagement elements make it possible for two adjacent floor covering elements to be pressed against one another with a spring force generated by the connecting element and thus to be connected to one another particularly reliably and without a gap.
  • the engagement elements that are resiliently fixed to or formed on the connecting section can also ensure that the connecting element is fixed and retained in a clamping manner in the relevant recess, thereby facilitating the laying of the floor covering.
  • each anchoring section of a connecting element has a cross-sectional area aligned parallel to the contact area with an approximately circular outer contour, and that each anchoring area of a recess in the floor covering element has a shape adapted thereto.
  • a recess with a circular cross-sectional area can be produced in a simple manner, for example by drilling a hole in the floor covering elements.
  • the recess in the floor covering element can therefore be produced cost-effectively, for example, by means of a blind hole and an adjoining milled groove for the connection area.
  • an upper side of the connecting element facing away from the bearing surface of the floor covering elements has a convexly curved surface.
  • the surface can have a chamfer running along the upper side edges, for example. It is also conceivable that the convex surface has a continuous curvature or rounded upper side edges. In this way, it can be avoided that a connecting element can cant when being inserted into a recess and the introduction of the connecting element into the recesses is made more difficult as a result.
  • an opening surface of the recess formed in the contact area in the floor covering element is smaller than one parallel to the contact area aligned cross-sectional area of the recess.
  • a recess which tapers towards the contact area can ensure that a connecting element arranged in the recess is retained in the recess, for example by an opening edge protruding inwards.
  • the dimensions of the connecting element and the inwardly projecting opening edge can be adapted to one another in such a way that the connecting element must be deformed somewhat when the connecting element is pressed into the recess in order to overcome the inwardly projecting opening edge of the recess.
  • the connecting element is then held back in the recess by the inwardly projecting edge of the opening. If a floor covering element is to be detached from the composite, if desired, the retaining force generated by the inwardly projecting opening edge must be overcome when it is pulled off the connecting element.
  • the connecting element By suitably adapting the shapes of the connecting element and the inwardly projecting edge of the opening, it is possible to ensure that the connecting element not only reliably fixes the floor covering element in all directions parallel to the subsoil, but also generates an additional restraining force that has an undesirable effect Displacement of the flooring elements prevented perpendicular to the ground. As a result, it can be avoided in a simple manner that individual floor covering elements laid loosely on the subsurface shift somewhat upwards due to normal use of the floor covering and thereby form an uneven surface of the floor covering.
  • an underside of the connecting element facing the bearing surface of the floor covering elements has a convexly curved surface.
  • the convex underside of the connecting elements like the top side, can have a lateral chamfer or rounded edges.
  • the underside of the connecting elements and the inwardly projecting opening edges of the recesses in the floor covering elements can have a shape that is adapted to one another in such a way that the connecting elements are accommodated in the recesses with essentially no play and a form fit of the anchoring sections of the connecting elements that acts in all directions in the associated anchoring areas of the recesses is effected.
  • This form fit can be established or released by a suitable configuration of the anchoring sections with resilient engagement elements by overcoming a retaining force in order to fix the connecting elements in the recesses or release them from the recesses again.
  • a particularly reliable composite effect of the floor covering composed of the floor covering elements can be achieved by a form fit of the anchoring sections of the connecting elements acting in all directions in the associated recesses of the floor covering elements.
  • the recess in the floor covering element is milled out with the aid of a ball-nose cutter.
  • the spherical milling cutter which dips into the recess perpendicular to the bearing surface, can be easily adjusted in the anchoring area of the recess by a Milling process caused lateral offset mill out an inwardly projecting opening edge or an undercut in a side wall of the recess.
  • the recess can also be produced within a comparatively short milling time using a special milling tool whose shape and cutting edges are specially adapted to the shape of the recess.
  • the special milling tool can, for example, resemble a ball milling cutter, the shank of which is also designed with cutting edges, at least in an area that faces the ball cutting edges and adjoins it.
  • the special milling tool penetrates the floor covering element during a milling process with the shank parallel to the bearing surface from the bearing surface, the anchoring area is milled out by the spherical cutters and the connection area of the recess is milled out by the cutters formed along the shank.
  • laterally displacing the immersed milling tool inwardly projecting opening edges or lateral undercuts can be produced in the side walls of the recess.
  • damping elements from a elastically deformable material are set.
  • the damping elements can be, for example, felt strips or felt plates that are self-adhesive or fastened with a separate adhesive.
  • the damping elements can also be flat strips or plates made of foam rubber or a suitable foam material.
  • connection element can be designed in one piece.
  • the connecting element can be produced, for example, from a suitable plastic material using a conventional injection molding process.

  • Resilient engagement elements can be produced in a simple manner by suitably shaping the one-piece connecting element.
  • the at least two floor covering elements each have a cuboid shape.
  • the floor covering elements accordingly have a rectangular or square contact area and a usable surface congruent thereto as well as planar side walls directed perpendicularly from the contact area.
  • Such floor covering elements can be produced quickly and inexpensively.
  • a reliable composite effect of several cuboid floor covering elements can already be achieved by a connecting element being arranged on each side surface and connecting the adjacent floor covering element adjoining this side surface.
  • a connecting element being arranged on each side surface and connecting the adjacent floor covering element adjoining this side surface.

  • the two connecting elements are easier and more reliable to connect with those arranged above Connect floor covering elements by pressing the floor covering elements onto the connecting devices resting on the ground and thereby pressing the two connecting elements into the respective associated recess in the floor covering elements.
  • a further advantage which is considered to be essential, is the possibility of being able to connect three or four adjacent floor covering elements to one another by means of a single connecting device.
  • two floor covering elements can be connected to one another with each connecting element, and up to four floor covering elements can therefore be connected to one another with the two connecting elements connected to one another via a common pressure plate.

It is not necessary to push individual floor covering elements to the side, which conventionally have to be connected to adjacent floor covering elements by means of a tongue and groove connection. In this way, floor covering elements with any shape of the base area can be connected to one another and, for example, numerous floor covering elements with an individual or matching shape can be joined together to form a star-shaped or wavy mosaic.
