Definitions

  • the invention relates to a floor covering element for forming a floor covering grid, in particular for forming a fall protection covering, according to the preamble of claim 1.
  • Floor coverings in particular fall protection coverings, are known per se.
  • covering elements or plates which in particular have a fall protection function, i. in that the covering acts to absorb energy relative to a force acting perpendicularly on the surface of the covering, so that a falling person - such as a child on a public or private children's playground - experiences comparatively low acceleration forces when hitting the covering.
  • the risk of injury decreases with a decreasing acceleration force.
  • a disadvantage of the known coverings is that they require the installation of a costly substructure and / or cover a vegetative, natural soil under the covering almost completely.
  • known fall arresting pads on flexible bridge parts wherein by a bending of the same the energy absorbing effect is achieved in the event of a force. Due to this permanent bending load on the bridge parts, the service life of the lining is reduced considerably.
  • the invention is therefore based on the object to provide flooring elements for forming a floor covering grid and for forming an arrangement of floor covering grids, which does not have the disadvantages of the prior art and at the same time inexpensive to produce, as well as universally applicable by a variable plug-in system.
  • a floor covering element for forming a floor covering grid has a first partial area forming a first side and a second partial area forming a second side, the floor covering element having a main extension direction parallel to the first and second sides and wherein the first partial area has at least one the course of the first side interrupting recess and the second portion has a in a direction perpendicular to the main extension direction of the recess overlapping third portion.
  • Variation of the height of the flooring element parallel to the vertical direction allows for variation of the fall protection capability of the flooring, as the amount or thickness of the more absorbent material varies with respect to a vertical force action on the flooring.
  • the fall protection capability, the visual effect and / or the water permeability of the floor covering are adjustable by adjusting the distance between the recesses in the main direction of extension, wherein preferably a floor covering element is provided with a plurality of recesses, which each have a constant distance from each other.
  • the number of recesses of a floor covering element is arbitrary, for example, at least two, at least 6 or at least 10 recesses, preferably 13 or 14 recesses, provided in a floor covering element.
  • the length of the recess is provided parallel to the main extension direction substantially equal to the width of the third portion perpendicular to the main extension direction and to the vertical direction, wherein particularly preferably the entire floor covering element has the constant width of the third portion.
  • a positive connection between a plurality of flooring elements is realized in the formation of a floor covering grid and thus the stability, in particular the torsional rigidity, of the floor covering grid significantly increased.
  • the variation of the width of the floor covering element allows a further adaptation of the fall protection capability, the optical effect and / or the water permeability of the floor covering.
  • an elastic material is used, so that a force acting on the floor covering element causes a reversible deformation of the same, for example.
  • the flooring element When a child falls on the floor covering or on entering the Flooring by one person.
  • This reversible deformation of the flooring element is provided for reducing an acceleration voltage, for example, when hitting the falling child, so that the floor covering element can be used in particular as an element of a fall protection covering.
  • the material has such an impact resistance that damage or irreversible deformation of the flooring element, for example, by breaking or tearing of the material when entering by persons or a plurality of persons is prevented.
  • the flooring element is in particular of a weather-resistant material, so that the flooring element in the outdoor area, ie outdoors, can be used and the usual environmental influences such as temperature fluctuations, moisture and sunlight without reducing the fall resistance, for example, at least over a plurality of years, ie that the floor covering element in Free preferably has at least one usual average longevity of known outdoor floors, in particular plastic outer floors.
  • the floor covering element has an overall length of 0.1 to 20 meters, preferably 0.2 to 10 meters and particularly preferably 0.25 to 3 meters, parallel to the main extension direction.
  • Such units of length of the flooring element ensure a comparatively simple handle and thus favor the assembly process of the floor covering elements. Furthermore, flooring elements of such lengths can be transported in a cost effective manner.
  • Another object of the invention is a floor covering grid with a plurality of flooring elements according to the invention, wherein a plurality of first flooring elements are arranged side by side and parallel to each other in a first direction and a plurality of second flooring elements in a direction perpendicular to the first direction second direction such side by side and parallel to each other arranged that the third portions of the first floor covering elements engage in the recesses of the second floor covering elements.
  • This grid arrangement wherein the first or second side of the first floor covering elements and the second or first side of the second floor covering elements form the visible side of the floor covering grid, has the advantage over the prior art that an aesthetic and natural effect of the floor covering by filling the grid clearances with a Filling material and / or by over- or overgrowth of the grid, for example.
  • a Filling material With grass, meadow and / or plants, achieved without limiting the fall protection capability.
  • sand and / or earth are provided as filling materials, thus at the same time achieving fixing of the floor covering grid to horizontal force effects on the floor covering grid.
  • Such a naturally appearing floor covering which at the same time has the highest possible fall protection capability, is of great importance, in particular with regard to its use on children's playgrounds, public squares, parks and / or in gardens.
  • a vegetative overgrowth of the floor covering grid is further promoted by the comparatively good water permeability of the floor covering grid.
  • no cost-intensive foundation of the soil is necessary, in particular because the risk of under-washing when using a grid structure is significantly reduced.
  • Another advantage is that the fall protection effect is achieved by a deformation of the floor covering elements themselves, so that no undermined structures are required, which are significantly shorter-lived by the permanent bending load.
