Definitions

  • the invention comprises a marking line system adaptable to the height of artificial turf according to the preamble of claim 1.
  • the marking line system is particularly suitable for sand-filled artificial turf tennis courts.
  • Commonly used court marking lines for tennis courts are made of flexible, hard plastic. Depending on the type of court, the marking lines are either anchored directly into the ground with nails or mounted on a rail system that is anchored to the ground. Especially on clay courts, marking lines are anchored directly into the ground with nails. Artificial turf is subject to significant wear, which gradually reduces the thickness or height of the turf surface. The marking lines, on the other hand, show hardly any wear. Over time, marking lines may protrude above the turf surface or become detached because the height of the artificial turf has decreased due to wear.
  • marking line systems with height-adjustable marking lines, such as in the Disclosure document EP 2 957 329 B1 described.
  • the marking line system according to EP 2 957 329 B1 This system allows the marking line height to be adjusted to the artificial turf height, thus accommodating the progressive wear and tear of the turf.
  • This marking line system features screw connections that serve as anchors and spacers between a lower and an upper profile section. The upper profile section can be adjusted in height relative to the lower profile section using these screws. This can take some time during assembly. Furthermore, screw connections are tricky in a sandy environment, as the sand can interfere with tightening.
  • a profile rail system for permanent field marking which is anchored in place in the playing field using anchor cables and pegs.
  • the system consists of a base rail with at least one anchor lug projecting into the ground on its underside and a replaceable covering on its upper side that marks the playing field.
  • This system also requires no screw connections, but is also not height-adjustable.
  • a cost-effective and, if possible, simple line system is to be provided.
  • Another object of the present invention is to provide a line system that can be adapted as easily as possible to a changing artificial turf surface, especially one that decreases in thickness.
  • the system aims to prevent marking lines from protruding beyond the surface.
  • Such a line system should also be cost-effective and have a simple and robust design. With such a system, the aforementioned disadvantages should be largely eliminated or at least partially avoided.
  • the line system in particular its lower profile part (13), is designed to be removable (e.g., by grinding), especially when laid out on a pitch, in order to define a lower marking line after removal than before. This allows the line system to be adapted to a decreasing or diminishing height of the artificial turf.
  • the gripping structures of the first profile section and the ribbed structure of the second profile section when the two sections are assembled, define a certain marking line height.
  • the gripping structures of the first profile section define the marking line height when the two sections are assembled, in particular by determining the height of the ribbed structure above the ground depending on the length of the gripping structures in a transverse view, and consequently, by determining the overall marking line height.
  • the first longitudinal gripping structure or the legs of the first profile part project into planes that lie above the ground support structure.
  • the first longitudinal gripping structure, or rather its legs, protrude beyond the base support structure, it can be ensured that, once the first profile section is mounted on the ground, the first longitudinal gripping structure, or the legs of the first profile section that stand out from the ground, can be planed, milled, sanded, or ground down from above without damaging the first profile section or compromising its integrity.
  • the base support structure retains its supporting function during planing, milling, or sanding and remains intact. Therefore, the height of the first profile section can be reduced as needed by planing, milling, or sanding, thus adjusting the height of the marking line to accommodate artificial turf that settles over time.
  • the line height therefore, depends significantly on the dimensions of the first profile section, or rather, the dimensions of the first longitudinal gripping structure.
  • the second profile section is removed before planing, milling, or grinding the first profile section and reattached after planing, milling, or grinding.
  • the existing second profile section can be replaced with a new one if necessary.
  • the extent to which the height of the line system, and thus of a marking line, can be changed can be determined by the difference in dimensions of the longitudinal gripping structures or the legs of the first and second profile sections.
  • the first longitudinal gripping structure has a first contact surface
  • the second longitudinal gripping structure has a second contact surface, wherein, in a cross-sectional view of the respective profile section, the contact surface of the first longitudinal gripping structure is longer than the contact surface of the second longitudinal gripping structure.
  • the first contact surface is at least 30%, or more preferably at least 50%, longer than the length of the second contact surface.
  • the inventive line system is particularly suitable for marking lines on artificial turf tennis courts. It is especially well suited for sand-filled artificial turf tennis courts.
  • the second longitudinal gripping structure is shorter than the first longitudinal gripping structure, or the legs of the second profile part are shorter than the legs of the first profile part.
  • the second longitudinal gripping structure is extended beyond the first longitudinal gripping structure.
  • This allows the first profile section (or the first longitudinal gripping structure or the legs of the first profile section) to be grasped or clamped by means of the second profile section (or the second longitudinal gripping structure or the legs of the first profile section).
  • This has the advantage that, in the assembled state, The second profile part clamps or grips the first profile part or the first longitudinal gripping structure across the cross-section from the outside, or the longitudinal sides of the first profile part from the outside, by means of the second longitudinal gripping structure.
  • the profile parts are designed such that the gripping structure of the first profile part has a greater length than the gripping structure of the second profile part, in particular such that the gripping structure of the first profile part supports the gripping structure of the second profile part or that the gripping structure of the second profile part does not abut the gripping structure of the first profile part.
  • the first longitudinal gripping structure has contact surfaces and the second longitudinal gripping structure has contact surfaces for mutually interlocking and/or clamping the at least one first profile part with the at least one second profile part, wherein, in cross-sectional extent or in cross-sectional view of the respective profile part, the contact surfaces of the first longitudinal gripping structure are longer than the contact surfaces of the second longitudinal gripping structure, preferably by at least 30%, more preferably by at least 50% of the length of the second contact surfaces.
  • the respective extent of the contact surface along a leg of the first longitudinal gripping structure can be longer than the respective extent of the contact surface along a leg of the second longitudinal gripping structure.
  • the first longitudinal gripping structure separates the longitudinal rib structure from the longitudinal floor support structure, so that in the assembled state there is a cavity between the longitudinal rib structure and the longitudinal floor support structure.
  • the at least one second profile part advantageously rests on or is supported by the first gripping structure of the at least one first profile part.
  • the longitudinal rib structure has a bottom and a top surface, and the second longitudinal gripping structure protrudes (or the longitudinal legs of the second profile part protrude) downwards from the underside of the longitudinal rib structure, so that in the assembled state the second profile part sits with the underside of the rib structure on the gripping structure of the first profile part, preferably on the leg end of the gripping structure of the first profile part, or is in direct contact with it.
  • the first longitudinal gripping structure or the contact surfaces formed thereon and the second longitudinal gripping structure or the contact surfaces formed thereon preferably have surface structures by virtue of which the two profile parts can be locked and/or clamped together or do lock and/or clamp together.
  • the profile parts can be connected to each other in particular by the fact that at least one second profile part can be placed or plugged onto at least one first profile part and the profile parts can be clamped and/or locked together (or snapped into each other) in particular under pressure (in particular a pressure which exceeds the pressure due to the weight of the second profile part).
  • first longitudinal gripping structure and the second longitudinal gripping structure interact in such a way that when the at least one first and at least one second profile part are joined together, a hollow profile with at least one longitudinal cavity is formed, or in the joined state, a hollow profile with at least one longitudinal cavity is present.
  • the first profile section is advantageously designed so that, when installed, it can be removed (e.g., sanded, planed, or milled) or modified by removal (e.g., grinding, planing, or milling) from the free end of the first gripping structure (or from the free end of the legs of at least one first profile section), particularly when the second profile section has been removed or not yet installed.
  • This has the advantage that the line height (marking line height) of the line system can be adjusted to the height of the artificial turf by removing, sanding, planing, or milling.
  • the first longitudinal gripping structure is longer than the second longitudinal gripping structure, and the first longitudinal gripping structure is designed in such a way that, in cross-section of the first profile part, it can be shortened by removal (in particular, for example, by grinding, planing, or milling) such that, after shortening, the two profile parts in their assembled state define a lower line height (marking line height) than before shortening.
  • the legs of the first profile part are longer than the legs of the second profile part, and the legs of the first profile part are designed in such a way that they can be shortened (preferably together) from their free ends by removing material (in particular, for example, by grinding, planing, or milling) such that, after shortening, the two profile parts define a lower line height in the assembled state than before shortening and, if necessary, form a longitudinal cavity in the assembled state whose cross-sectional area is smaller than before shortening.
  • the second profile section By shortening, for example by grinding, planing, or milling, the first longitudinal gripping structure or the legs of the first profile section, the second profile section can be positioned closer to the ground than before shortening. This results in the slat structure, which is part of the second profile section, being positioned closer to the ground after shortening. The height of a slat structure laid on the ground can thus be adjusted to compensate for the decreasing height of the artificial turf over time due to wear.
  • the profile sections can be slid against each other, particularly along the legs in the direction of the leg depth. Therefore, the mutual distance between the parallel profile sections can be adjusted or shortened in a direction normal to the longitudinal orientation of the profile sections.
  • the first profile part or in particular the longitudinal floor support structure, is designed with a base, preferably by the longitudinal floor support structure having bases which are designed, for example, as longitudinal side structures of the longitudinal floor support structure.
  • At least one first profile section and/or at least one second profile section are made of plastic and/or aluminum. Profile sections made of plastic are particularly preferred.
  • the longitudinal rib structure of the at least one second profile section typically has a top and a bottom surface.
  • the top surface can be ribbed, particularly longitudinally ribbed, making it suitable as a marking line because it is relatively non-slip.
  • the at least one second profile section can have mounting structures, preferably on the longitudinal rib structure, onto which a marking line, preferably with a surface texture, can be clamped.
  • the second profile section, or its longitudinal guide structure preferably forms a substantially flat surface, the height of which can be adjusted to match the artificial turf by machining (such as grinding, planing, or milling) the gripping structure of the first profile section.
  • the aforementioned substantially flat surface can be equipped with a non-slip surface, for example, a ribbed or studded surface structure and/or a non-slip material.
  • the first longitudinal gripping structure is preferably designed in the form of at least two longitudinal legs
  • the second longitudinal gripping structure is preferably also designed in the form of at least two longitudinal legs. wherein the at least two longitudinal legs are aligned in such a way that the at least one second profile part can be attached and/or clamped onto the at least one first profile part by allowing the two legs of one profile part to engage with the legs of the other profile part.
  • the base support structure connects the at least two longitudinal legs of the first longitudinal gripping structure in a spaced-apart parallel arrangement (fixed).
  • a first embodiment of a line system according to the invention is shown in Fig. 1 in a sectional view transverse to the longitudinal extent of the line system 11, or in a cross-section of the profile parts 13 and 15. This representation particularly clarifies the arrangement of the profile parts 13 and 15 in their assembled state of an installed, ready-to-use line system.

  • a lower profile section or several lower profile sections 13, 13' or 13" are designed such that the respective upper profile section(s) 15, 15' or 15" can be plugged onto the lower profile section(s) 13, 13' or 13" respectively.
  • Upper profile sections can extend over points where two lower profile sections abut each other in their longitudinal direction; conversely, lower profile sections can extend over points where two upper profile sections abut each other in their longitudinal direction. This means that the upper and lower profile sections can be inserted into each other with a longitudinal offset. This allows for the creation of particularly stable marking line systems that are longer than the individual lower and/or upper profile sections.

  • the legs 25 and 27 of the lower profile part 13 are so much longer than the legs 21 and 23 of the upper profile part 15 that even after one or preferably several grinding, planing or milling of the lower profile part 13 or after one or several shortening of the length of the legs 25 and 27 of the lower profile part 13, an upper profile part 15 can be placed on top again and, if necessary, snapped into place, so that the seating surface 69 of the upper profile part 15 sits on the ends 73 of the legs 25 and 27 of the lower profile part 13.
  • lateral support feet 65, 67 should be attached as low as possible (i.e., close to the ground) to the lower profile and be thin, because this ensures maximum overlap of the legs 21, 23 of the upper profile part 15 over the legs 25, 27 of the lower profile part 13.
  • the gripping structure 25, 25', 27, 27' (or the legs) of the lower profile part 13, 13' is (are) advantageously designed in cross-sectional view of the profile part (at least in its new state or during initial assembly) such that the extent of the gripping structure 25, 25', 27, 27' of the lower profile part (in particular, for example, from the leg base 71, 71', 75, 75' to the leg end 73, 73', 77, 77') has (have) a greater length than the gripping structure 21, 21', 23, 23' of the upper profile part (or the legs, i.e. in particular the thighs from the thigh insertion 81, 81', 85, 85' to the thigh end 83, 83', 87, 87').
  • the gripping structure 25, 25', 27, 27' of the lower profile part 13, 13' has a greater length than the gripping structure 21, 21', 23, 23' of the upper profile part 15, 15', in particular such that the gripping structure 25, 25', 27, 27' of the lower profile part 13, 13' supports the gripping structure 21, 21', 23, 23' of the upper profile part 15, 15', but the gripping structure 21, 21', 23, 23' of the upper profile part 15, 15' does not abut the gripping structure of the lower profile part (or neither the gripping structure of the lower profile part nor anywhere else on the lower profile part).
  • this ensures that the leg ends 83, 83', 87, 87' of the upper profile section 15, 15' remain free and are not in contact with the lower profile section 13, 13'.
  • This allows the upper profile section to be placed onto the lower profile section in such a way that, when assembled, the leg ends of the gripping structure of the lower profile section support the upper profile section without the ends 83, 83', 87, 87' of the gripping structure of the upper profile 15, 15' striking the lower profile 13, 13'.
  • This also ensures that the gripping structure of the lower profile section, or its leg ends 73, 73', 77, 77', can be ground down if necessary to adapt the height of the line system to a change in the artificial turf height.
  • the lower profile section 13, 13' has one or more cavities 17, 17', 19, 19' between its profile legs 25, 15' and 27, 27'.
  • the cavity(ies) 17, 17', 19, 19' preferably extend along the entire length of the profile section 13, 13'. Extending the entire length of the profile section 13, 13' offers advantages in terms of manufacturing and also facilitates cleaning, e.g., with a broom, when the upper profile section 15, 15' is not seated.
  • the cavity 17, 17', 19, 19' contained in the first profile section 13 is covered from above by the second profile section, or more specifically by its rib structure 61, 61'.
  • Each of the cavities 17, 17', 19, 19' forms a channel along the longitudinal extent of the first, lower profile section 13, 13' or the rib system.
  • the cavities 17', 19' can be filled with sand after the lower profile sections 13' have been laid, which improves the stability of the installed rib system.
  • the rib structure 61, 61' of the upper profile section 15, 15' may include transverse slots along its longitudinal extent (not shown in the figures). Such transverse slots may allow sand to penetrate into the cavities 17, 19 even after the assembly of the line system 11, 11". This more complex design of the upper profile section can be produced, for example, by introducing transverse slots in a machining step following extrusion.
  • the lower profile section 13, 13' can expediently have projecting support structures 65, 65', 67, 67' on the respective longitudinal outer side of the profile legs 25, 25' and 27, 27', i.e., on the outer side facing away from the cavity 17, 17', 19, 19'.
  • These support structures 65, 65', 67, 67' can be designed on the lower profile section 13, 13' as essentially flat plates, which project from the legs 25, 25' and 27, 27' respectively at an angle of approximately 90° (i.e., essentially horizontally) on the bottom side and thus act as a base for the linear system.
  • the artificial turf which is expediently designed as a carpet, advantageously lies on the additional, projecting support structures 65, 65', 67, 67' on both sides of the lower profiles 13, 13' after installation, thereby stabilizing the position and orientation of the lower profile part 13, 13' or the fully assembled line system.
  • the upper profile section 15, 15' can have further retaining structures (not shown in the figures) that allow a marking line, e.g., made of hard plastic, to be clipped on.
  • retaining structures could, for example, be provided longitudinally on the outside of the upper profile section 15, 15', which could be designed as undercuts onto which, for example, a marking line with laterally curved clamping structures could be clipped.
  • the artificial turf sections and the 11, 11', 11" track system are laid in such a way that the edges of the artificial turf sections rest on the support feet 65, 67, 65', 67' of the lower profile section 13, 13'.
  • the upper profile section 15, 15' can be pre-mounted onto the lower profile section 13, 13' at the factory before installation or alternatively, it can be mounted on-site.
  • the height of the slat system can be adjusted to the height of the artificial turf on the installed lower profiles 13, 13' before the upper profiles 15, 15' are installed, or after the upper profiles 15, 15' have been removed. Where the leg ends 73, 73', 77, 77' and/or the end of the support structure 49, 49' of the lower profile 13, 13' rise too high or above the artificial turf, they can be trimmed back to such an extent that the slat height of the subsequently installed slat system corresponds approximately to the current thickness of the artificial turf.
  • the upper profile part 15, 15' is placed onto the lower profile part 13, 13', so that the legs 25, 25', 27, 27' of the lower profile part 13, 13' can engage with the legs 21, 21', 23, 23' of the upper profile part 15, 15'.
  • the upper profile part 15, 15' can be pressed onto the lower profile part 13, 13', snapping into place.
  • the strip structure 61, 61' of the upper profile part 15 rests on the free ends of the leg pair 25, 25', 27, 27' and, if applicable, the support structure 49, 49' of the lower profile part 13, 13'.
  • the upper profile part 15, 15' is attached to the lower profile part 13, 13' by mutually interlocking the toothed leg sides 31, 31', 33, 33', 35, 35', 37, 37'.
  • the slat height resulting from joining the two profile parts 13, 13', 15, 15' depends on the leg length of the legs 25, 25', 27, 27' of the lower profile part 13, 13'.
  • the aim is to adjust the height of the line system to the current artificial turf height, so that the surface of the artificial turf carpet and the surface of the marking line are at approximately the same horizontal height level.
