Definitions

  • the invention relates to a floor covering according to the preamble of claim 1 and to a method for its production and to the use of such a floor covering.
  • Floor coverings made of non-woven, textile fabrics are known in countless variants and embodiments. Likewise, various methods for producing such floor coverings and a wide variety of fields of application are known. A possible area of application for such floor coverings is tennis courts both indoors and outdoors, with additional requirements being placed on the flooring in the outdoor area.
  • a needle fleece designed as a sports floor covering is known.
  • the top of this sports floor covering is designed as a coarse-textured, loop-less needle felt. Rubber granules are introduced into and on this roughly structured upper side, so that such a floor covering can also be used as a tennis court covering.
  • When laying this sports floor covering is glued to the underlay on its relatively flat, flat underside.
  • a disadvantage of such a floor construction is that it can only be used in halls or covered areas, since in the event of a rain shower, the water does not run off can and the place is therefore unplayable for a long time.
  • a tennis floor covering is known from EP 0 216 953 A3, the upper side of which is structured in a rib-like or waffle-like manner with elevations and depressions for receiving granular granules. From the drawing shown in section in this document and the associated description, it follows that the back of this tennis floor covering is designed to correspond to the top. However, in the case of a rib-shaped as well as a waffle-like configuration of the underside, such a tennis floor covering is not suitable for use outdoors.
  • floor coverings are also known which have a multiplicity of grid-like plastic or latex knobs on their back.
  • Such knobs can improve the outflow of water under the floor covering, but a floor covering provided with such knobs has other disadvantages which make the use of this floor covering unsuitable as a tennis or sports field covering.
  • the plastic or latex knobs reduce that water permeable surface.
  • such knobs and the connection between the floor covering and the knobs have only a low shear and tear resistance and are subject in particular to a certain aging due to the large temperature differences occurring outdoors, as a result of which the aforementioned shear and tear resistance decrease even further.
  • such floor coverings are very expensive to manufacture, since the knobs must be applied in a separate operation and on a machine specially equipped for this purpose.
  • Another object of the invention is to design a floor covering such that it has good drainage, in particular for rain water, and that it is also long-term resistant and can withstand high mechanical loads.
  • Another object of the invention is to propose a method for its production and a use for such a floor covering.
  • the floor covering In a preferred embodiment of the floor covering, it has a depression on the side opposite the elevations in the region of the elevations. This on the one hand increases the surface of the floor covering and on the other hand reduces its thickness in these areas. This helps to drain the water quickly from the top to the back of the flooring.
  • Another preferred form of training of the floor covering provides for the elevations to be arranged in columns and rows.
  • the installed floor covering has a networked duct system on its back so that water can drain off optimally.
  • Fig. 1 shows schematically in a cross section a non-woven fabric formed as a floor covering 1.
  • the floor covering 1 is shown in an enlarged, not to scale section.
  • the floor covering 1 has elevations 4 in the form of ribs or velor, which complement one another to form a surface structure.
  • Such surface structures can take on a wide variety of tasks. If the floor covering 1 is to be used, for example, as a tennis court covering, this structure is used to hold granules. These and other tasks of such structures are known, which is why they are not dealt with in more detail here.
  • the floor covering 1 On its underside 3, the floor covering 1 has island-like and integrally formed knobs 5. These knobs 5 are preferably produced by needling and are by a Variety of individual fibers formed. The needling creates a depression 6 opposite the knobs 5. These depressions 6 on the one hand enlarge the surface of the floor covering 1 and on the other hand reduce the thickness of the floor covering 1 in the area of the knobs 5. This allows water falling on the floor covering 1 to pass through them more quickly flow in and out. The formation of the knobs 5 from individual, non-woven fibers also favors the rapid drainage of water. The direction of flow of the water through the floor covering 1 is indicated by arrows P.
  • the knobs 5 are preferably arranged in rows and columns, as shown in FIG. 2, the knobs 5 themselves being able to have a size of approximately 5 ⁇ 10 mm and a height of approximately 3 mm.
  • the distance between the knobs 5 is approximately 25 mm in the longitudinal direction of the knobs 5 and approximately 15 mm in the transverse direction. This information is only to be regarded as a guideline and can vary greatly depending on the expected load, type of load and location. Due to the relatively large distances between the individual knobs 5 and the space s remaining due to the height of the knobs 5, between the underside 3 of the floor covering and the actual sub-floor, the water can flow off quickly and without any appreciable resistance. It is irrelevant how and in which direction the underlay is inclined. To the floor covering 1 in the initial state to a distinctive appearance and to mark the side to be glued, the knobs 5 can also be highlighted in color compared to the rest of the flooring 1.
  • FIG. 3 shows in a highly simplified representation a longitudinal section through the starting material 10 for the floor covering and a first needle chair 11 of a structural needle machine.
  • the formation of a single elevation 4 in the form of a rib is shown in a snapshot.
  • the method for forming such ribs 4, which complement one another to form a surface structure, is explained below with reference to this figure. Since such methods are known, the following explanations are limited to the essentials.
  • the needle chair 11 itself essentially consists of a needle board 12 and a slatted frame 13 which has longitudinal slots 15 in the region of the elevations to be formed.
  • Six needles 14 lying in a row are shown on the needle board 12. It goes without saying that further rows of needles are arranged in planes parallel to the plane of the drawing, offset to the rear, but for the sake of clarity they are not shown here. In order to create a certain surface structure, the distance between the individual rows of needles can be different.
  • the arrangement of the needles 14 on the needle board 12 corresponds to the desired structure to be formed on the upper side of the starting material 10 or the floor covering.
  • the needles 14 themselves have on their front preferably a U-shaped notch, which has been omitted in the drawing for clarity.
  • a flat nonwoven is generally used as the starting material 10 for the floor covering.
  • This flat fleece 10 is provided with a surface structure in a known manner by the interaction of the needle board 12 and the slatted frame 13 in this first step.
  • the ribs 4 are formed by inserting the needles.
  • the flat nonwoven 10 is continuously moved forward in the direction of the arrow. This creates ribs 4 that are slightly longer than the distance between the two outermost needles.
  • the formation of the ribs 4 by means of needling creates recesses 7 on the side of the fleece opposite the formed ribs 4. Since a needle board 12 usually has several thousand needles 14, hundreds of ribs 4 are formed simultaneously.
  • needle boards 12 can also be used, which have several groups of rows of needles one behind the other.
  • FIG. 4 shows the second operation, to which the floor covering 1 formed according to the previous description is subjected. After retrofitting, this can be done both on the same structural needle machine as in the previous work step and on another similar or identical machine.
  • the floor covering 1 and a needle chair 11A consisting of a needle board 12A and a slatted base 13A can be seen in longitudinal section, the slatted base 13A again having longitudinal slots 15A in the region of the knobs to be formed.
  • the floor covering 1 is shown in this illustration, compared to FIG. 3, in a longitudinal section offset parallel to the plane of the drawing.
  • the needle board 12A Six needles 14A lying in series are drawn on the needle board 12A, which in turn have a U-shaped recess (not shown) on their front side, the distance between the individual needles 14A being the same as the distance between the respective start of two neighboring ones to be formed Knobs 5.
  • This needle board 12A also has further rows of needles in planes parallel to the plane of the drawing and offset to the rear.
  • the floor covering 1 formed from the flat fleece is rotated for this second work step, so that it comes to lie with the ribs 4 upwards, and the knobs 5 can thereby be formed on the side opposite the ribs 4.
  • knobs 5 are in turn formed by the interaction of the needle chair 12A with the slatted frame 13A, the formation of a single knob 5 being divided into six work steps.
  • the floor covering 1 is continuously moved in the direction of the arrow to carry out this method.
  • the needles 14A are inserted, there are individual ones Fibers from the upper area of the floor covering 1 are taken along by the needle and pulled down into the desired shape.
  • a single knob 5 is produced in six working steps by successively inserting the six individual needles 14A lying in series, the floor covering 1 being continuously transported between the insertion of the first, leftmost needle and the respective subsequent insertion of the next needle, in each case by the amount of the distance between two needles.
  • knobs 5 Due to the continuous transport of the floor covering 1 during the insertion of the needles 14A, an elongated configuration of the knobs 5 is achieved.
  • the needles 14A are shown at the beginning of the piercing process. Instead of six needles 14A for the formation of the knobs 5, any other number of needles can of course also be selected. In this case, the number of operations for forming a single knob is again adjusted to the number of needles.
  • This method in turn produces recesses 6 on the side of the floor covering 1 opposite the formed knobs 5. It goes without saying that several knobs 5 are also formed simultaneously in this method.
  • the two-sided treatment of the floor covering 1 After the two-sided treatment of the floor covering 1, it is impregnated, for example, by means of a back splash process. Care is taken to ensure that the water permeability of the floor covering 1 remains guaranteed.
  • the knobs 5 By forming the knobs 5 from individual fibers and the respective recesses 6 behind them, the outflow of water via the knobs 5 is also promoted.
  • a floor covering 1 designed in this way can be used in a wide variety of areas, but due to its very good drainage properties it is preferably used in areas with periodic wetness. For example, it is ideal as an outdoor tennis court surface. In order to keep the loads, in particular on the joints of the tennis players, within limits, granules can be introduced into and onto the top 2 of the floor covering provided with a structure.
  • such a floor covering 1 can also be used as a lawn carpet.
  • Floor covering 1 is also ideal as a dirt lock in a wide variety of areas.
  • such a floor covering 1 also has very good damping properties, which is reflected in a pleasant spring behavior when walking on the covering 1.
  • the floor covering 1 has to withstand higher mechanical loads, for example when used as a tennis court covering, so he or the knobs 5 is generally glued to the sub-floor. In the outdoor area, such a sub-floor usually has a slight slope.
  • the adhesive is applied in the form of a strip, in such a way that the grooves formed run parallel to the gradient of the underlay floor. As a result, the drainage properties of the floor covering 1 can be maintained.
  • such a floor covering 1 through the integral design of the knobs 5, has a very high wear resistance, in particular with regard to acting thrust and shear forces, with very good drainage properties at the same time.
  • the surface structure of the floor covering 1 can be chosen freely and adapted to individual needs.
  • the surface can be designed to receive granules, so that such a floor covering 1 is suitable as a tennis court covering, in particular for the outdoor area.
  • the floor covering 1 also has very pleasant damping properties.
