Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0057] In the following, embodiments of the invention are explained in greater detail, by way of example only, making reference to the drawings, in which:

[0058] FIG. 1 illustrates a schematic sectional view of the structure of a sports flooring with a top layer arranged above a dynamic layer;

[0059] FIG. 2 illustrates a schematic sectional view of a top layer arranged above a dynamic layer, the dynamic layer comprising microporous zeolite mineral particles; and

[0060] FIG. 3 illustrates a schematic sectional view of a top layer arranged above a dynamic layer, both layers comprising microporous zeolite mineral particles.

[0061] Like-numbered elements in these figures either are equivalent elements or perform the same function. Elements that have been discussed previously will not necessarily be discussed in later figures if the function is equivalent.

[0062] FIG. 1 illustrates a sectional view of a sports flooring 100 with a top layer 110 arranged above a dynamic layer 120. The top layer 110 comprises material selected from the group consisting of crushed shale, crushed stone, crushed brick, quartz sand and volcanic ash, or a mixture thereof. The top layer 110 may comprise microporous zeolite mineral particles. The dynamic layer 120 is provided with a layer thickness LT of 5 to 13 cm, preferably with a layer thickness of 6 to 10 cm, and is arranged below the top layer 110 and above a base layer 130, which is arranged above the soil layer 150. The dynamic layer 120 comprises a composition comprising lava particles and/or limestone particles and/or clinker particles, which are mixed with microporous zeolite mineral particles. The microporous zeolite mineral particles may be present in the amount of 4% to 65%, 4% to 10%, 10% to 20%, or 30% to 50% of the total mass of the composition. For some embodiments, the grain size of the microporous zeolite mineral particles is between 0.4 mm and 12 mm. If a filter layer 140 is present, the filter layer 140 is arranged between the base layer 130 and the soil layer 150. The sports flooring 100 can be constructed on ground areas intended for use in tennis, football, soccer, handball, basketball, badminton or other ball games. In the shown embodiment, however, the sports flooring 100 is a sports flooring for soft-surface courts, in particular so-called clay courts, sand courts or ash courts.

[0063] FIG. 2 illustrates a schematic sectional view of a top layer 110 arranged above a dynamic layer 120, wherein the dynamic layer 120 comprises microporous zeolite mineral particles 125. The top layer 110 is a common soft-surface top layer, comprising at least one material 111 selected from the group consisting of crushed shale, crushed stone, crushed brick (clay), quartz sand and volcanic ash, or a mixture thereof, wherein the grain size of the top layer particles is smaller than 3.15 mm. The dynamic layer 120 comprises a composition comprising a mixture of lava particles 121 and/or limestone particles 122 and/or clinker particles 123 and microporous zeolite mineral particles 125, wherein the microporous zeolite mineral particles 125 are present in the amount of 4% to 65% of the total mass of the composition and wherein the grain size of the microporous zeolite mineral particles 125 is between 0.4 mm and 12 mm.

[0064] FIG. 3 illustrates a schematic sectional view of a top layer 110 arranged above a dynamic layer 120, both layers 110, 120 comprising microporous zeolite mineral particles 115, 125. The top layer 110 of this embodiment comprises a composition comprising at least one material 111 selected from the group consisting of crushed shale, crushed stone, crushed brick (clay), quartz sand and volcanic ash, or a mixture thereof, as well as microporous zeolite mineral particles 115. The microporous zeolite mineral particles 115 are present in the amount of 5% to 70% of the total mass of the top layer 110. The grain size of the microporous zeolite mineral particles 115 of the top layer is between 0.03 mm and 2.2 mm. The grain size of at least one material 111 selected from the group consisting of crushed shale, crushed stone, crushed brick (clay), quartz sand and volcanic ash is smaller than 3.15 mm. The dynamic layer 120 comprises in this embodiment a composition comprising a mixture of limestone particles 122 and microporous zeolite mineral particles 125, wherein the microporous zeolite mineral particles 125 are present in the amount of 4% to 65% of the total mass of the composition and wherein the grain size of the microporous zeolite mineral particles 125 is between 0.4 mm and 12 mm.
