Definitions

  • the invention relates to a floor tile for the production of coverings on the floor of sports facilities according to the preamble of claim 1.
  • Floor coverings for indoor and outdoor sports facilities which are composed of floor tiles, preferably plastic tiles, are particularly suitable for the efficient and inexpensive renovation of outdated sports fields.
  • Such modular floor coverings are used in particular for tennis, football and basketball courts.
  • many of these flooring products offer little to no shock absorbing properties, resulting in increased fatigue and increased stress on ligaments, joints and discs from walking, running, jumping or other activities on the flooring.
  • synthetic floor tiles are made from a rigid or semi-rigid material.
  • a modular floor tile for producing a floor covering for sports fields is from the document US 2016/0222674 A1 CERNY ET AL. known.
  • This known modular floor plate has a surface with a large number of ribs or structural elements.
  • a one-piece support system in the form of a grating is formed by the ribs or structural elements.
  • the base plate comprises primary support elements, one of which is arranged in each opening of the grating between the rib elements.
  • Each primary support element comprises a central support post, which rests on the floor even in the unloaded state of the base plate, and a plurality of flexible arms which are connected to the grating, the arms extending outwards from the central support post.
  • the invention aims to remedy this.
  • the invention is based on the object of creating a floor tile with damping properties that are gentle on the joints and that can be produced simply and inexpensively.
  • the invention achieves the stated problem with a floor tile for the production of coverings on the floor of sports facilities, which has the features of claim 1.
  • the plate-shaped or shell-shaped and elastically bendable cover elements produce a sufficient spring force and no abrupt end of the spring travel is generated
  • a shock-absorbing floor covering for sports facilities can be produced which, due to its cell structure with plate or shell-shaped and elastically deflectable cover elements, ensures simple and inexpensive production of the floor covering compared to known floor tiles with spring elements, which each have several arms and support posts; and
  • the floor covering does not require any additional top layer.
  • the ratio FD: FZ is at least 70%, preferably at least 80%.
  • the plate or shell-shaped cover elements form thin plates or shells which are bent when a load is applied and which, even with a relatively small thickness, can have a higher flexural rigidity than linear arms which are subjected to bending loads.
  • the cover elements can be convexly curved towards the top in the shape of a shell. This has the advantage that the introduction of force when a load occurs on the top of the cover elements is preferably carried out in the middle of the cover elements.
  • the cover elements can have recesses in the corners of the polygonal cells. This results in the advantage that there is no accumulation of material at the corners of the polygonal cells, which would constitute a considerable disadvantage, in particular when the floor tile is manufactured using injection or die-casting techniques. This also prevents rainwater from collecting.
  • the cover elements can - as viewed from the top - comprise a central recess.
  • the central recess has the advantage that rainwater does not collect and run off on the upper side of the plate-shaped or shell-shaped cover elements.
  • the central recess has the effect that the plate-shaped or shell-shaped cover elements become more flexible.
  • the cover elements can also include pins or knobs on the top.
  • the pins can increase the slip resistance (grip) of the floor tile, in particular also in wet conditions in the case of outdoor arrangements of the floor covering.
  • grip slip resistance
  • the cover elements can - viewed from the top - have a center and the pins or knobs can be evenly distributed around the center on one or more circles.
  • Each cover element advantageously comprises at least six pins or knobs.
  • the pins or knobs can expediently be arranged on the mid-perpendicular of the partition walls.
  • the pins have a height H which is expediently at least 0.5 mm, preferably at least 0.7 mm.
  • the height H of the pins is expediently at most 1.0 mm, preferably at most 0.8 mm.
  • the cover elements have a curvature with a height h which is expediently a maximum of 1.8 mm, preferably a maximum of 1.2 mm.
  • the cover elements can expediently be elastically deflectable by at least 0.7 mm, preferably by at least 1.0 mm, against the underside.
  • the cover elements can expediently be elastically deflectable against the underside by a maximum of 1.8 mm, preferably by a maximum of 1.2 mm.
  • the cells - viewed from the top - each have the shape of a regular polygon.
  • the cells can each have the shape of an equilateral hexagon.
  • the advantage of this arrangement is that in each case in a node, i. in one corner of the cell, only meet three partition walls, so that the accumulation of material can be minimized.
  • the equilateral hexagon expediently has an internal dimension of at least 30 mm, preferably at least 32 mm, between two parallel sides.
  • the equilateral hexagon expediently has an internal dimension of at most 40 mm, preferably at most 38 mm, between two parallel sides. Typically the inside dimension can be 35 mm.
  • the cells can be designed as a prism, preferably as a straight prism.
  • the floor tile can be square and have four sides, the cells advantageously being arranged such that seven cells are arranged next to one another in the direction of a first side.
  • the advantage of this embodiment is that there is a smooth transition from tile to tile for a standard tile dimension of 10 inches x 10 inches, ie the suspension of the edge cells is not disturbed by additional partition walls because the connection is made at a node. Furthermore, when several floor tiles are joined together, a flowing visual transition of the hexagonal cells of the individual floor tiles, so that a uniformly harmonious surface of the floor covering results.
  • the seven cells lined up in a row in the direction of the first side are arranged with parallel partition walls of the equilateral hexagon arranged next to one another.
  • the cells arranged in the direction of a second side, which is perpendicular to the first side, can each have two cells on the outside, which are centrally separated from two opposite corners of the hexagon.
  • the cover elements can have a thickness that increases in relation to the partition walls. This enables a substantially constant tension to be achieved in the cover elements.
  • the thickness of the cover elements in the area of the partition walls is expediently at least 1.8 mm, preferably at least 2.0 mm.
  • the thickness of the cover elements in the area of the partition walls is expediently at most 2.5 mm, preferably at most 2.2 mm. Typically the thickness in this area is 2.1 mm.
  • the thickness of the cover elements in a central area of the cell viewed from the top is expediently at least 0.8 mm, preferably at least 1.0 mm.
  • the thickness of the cover elements in a central area of the cell viewed from the top is expediently at most 1.4 mm, preferably at most 1.2 mm. Typically, the thickness in this area is 1.1 mm.
  • the floor tile is advantageously formed in one piece. This enables the floor tile to be manufactured by injection molding or die casting.
  • the cover elements can have radially extending depressions on a surface directed towards the underside of the floor tile. These recesses form segments of the cover elements, which provide soft, 3-dimensional cushioning when the sports shoe hits the top of the floor tile ensure that joints and intervertebral discs are protected from hard blows.
  • the floor tile can have four sides and comprise spring clips on two mutually perpendicular sides and plug-in elements that can be snapped into the spring clips on the opposite sides.
  • the spring clips and the plug-in elements form a snap connection system for connecting several floor tiles for lowering a surface on the floor of a sports facility and are preferably designed so that the floor tiles according to the invention can also be combined with other, already known floor tiles.
  • the spring clips can also be designed to be elastically deformable in both directions parallel to the respective sides.
  • the spring clips and plug-in elements enable a resilient displacement of the floor tiles relative to one another in two axial directions parallel to the top.
  • the partition walls can be formed recessed from the top with respect to the cover elements.
  • the floor tile can advantageously be made from a flomopolymer or copolymer, preferably from a polypropylene.
  • the rigidity of the plate or shell-shaped cover elements is expediently designed so that at maximum load the limit stress of the material from which the floor tile is made is a maximum of 35 N / mm 2 .
