Abstract

The cover plate serves for covering drainage ditches (1) of known design at sports grounds and allows good surface drainage whilst reducing the risk of accidents for sportsmen. For this purpose, it consists of a profiled plate, for example made of aluminium, which is placed on the shoulder faces (6) and edge-side support walls (11), has centrally arranged water drainage slots (13), and is provided between the latter with fastening ribs (12) for fastening edge elements (20). The height of the support walls (11) together with the thickness of the edge elements (20) above the support walls (11) is approximately equal to the height of the ribs (5) of the drainage ditches (1). The water can thus flow off easily. If the edge elements (20) consist of a caoutchouc of Shore A hardness 75, there is no risk of injury for sportsmen. Additionally, the edge elements (20) can be coloured white for the running track side and green or red for the lawn side. <IMAGE>

Description

Die vorliegende Erfindung betrifft ein Abdeckelement für Entwässerungsrinnen gemäss dem Oberbegriff des unabhängigen Patentanspruchs 1.The present invention relates to a cover element for drainage channels according to the preamble of independent claim 1.

Bei Sportplätzen ist es gemäss dem DE-U-7030096 oder dem DE-U-7127601 bekannt, für die Laufbahnränder oder für Sportgrubeneinfassungen die Ränder mit weichelastischen Elementen abzudecken. Um die Oberflächen von Hartbelagsstellen zu entwässern, sind unter den Abdeckungen Druchgänge ausgespart worden. Die Elemente sind leicht entfernbar und auswechselbar befestigt. Da jedoch das Wasser bei starken Regenfällen stehen bleibt, ist die Frage entstanden, ob es nicht machbar wäre, bekannte Entwässerungsrinnen mit Abdeckungen auszurüsten, die dieselbe Funktion wie bei den bekannten Rand-oder Sportgrubeneinfassungen auszuüben vermögen.In sports fields, it is known from DE-U-7030096 or DE-U-7127601 to cover the edges with soft elastic elements for the raceway edges or for sports pit borders. In order to drain the surfaces of hard surface areas, passages have been left underneath the covers. The elements are easily removable and replaceable. However, since the water stops during heavy rainfall, the question arises whether it would not be feasible to equip known drainage channels with covers that can perform the same function as in the known edge or sports pit enclosures.

Es sind heute schon Rinnenabdeckungen bekannt, die aus Kunststoff gebildet sind, die aber ausbrechen und durch Sportler oder Bodenbearbeitungsmaschinen aus den Rinnen herausgebrochen werden können und dadurch zu Verletzungen führen können.Gutter covers are already known today, which are made of plastic, but which break out and can be broken out of the gullies by athletes or tillage machines and can thus lead to injuries.

Dementsprechend besteht die Aufgabe der Erfindung darin, eine Abdeckung zu schaffen, die die Anforderungen für Sportplatz-Ränder voll erfüllen.Accordingly, the object of the invention is to provide a cover that fully meets the requirements for sports field edges.

Erfindungsgemäss wird dies durch die Merkmale des Patentanspruchs 1 erfüllt.According to the invention, this is achieved by the features of patent claim 1.

Ausführungsbeispiele der Erfindung werden nachfolgend anhand der Zeichnung erläutert. Es zeigen:

  • Fig. 1 eine Schnittansicht einer ersten Form einer Abdeckung nach der Erfindung in einer geschnitten dargestellten Entwässerungsrinne,
  • Fig. 2 eine Schnittansicht einer zweiten Form einer Abdeckung auf einer nur teilweise dargestellten Entwässerungsrinne,
  • Fig. 3 eine Draufsicht auf die Ausführungsform nach Fig. 2,
  • Fig. 4 eine Schnittansicht einer dritten Form einer Abdeckung auf einer ebenfalls nur teilweise dargestellten Entwässerungsrinne, und
  • Fig. 5 eine Draufsicht auf die Ausführungsform nach Fig. 4.
Embodiments of the invention are explained below with reference to the drawing. Show it:
  • 1 is a sectional view of a first form of cover according to the invention in a drainage channel shown in section,
  • 2 is a sectional view of a second form of cover on a drainage channel, only partially shown,
  • 3 is a plan view of the embodiment of FIG. 2,
  • Fig. 4 is a sectional view of a third form of cover on a drainage channel, also shown only partially, and
  • 5 is a top view of the embodiment of FIG. 4.

Fig. 1 zeigt eine Entwässerungsrinne in allgemein bekannter Ausführungsform, die als Rinnenelemente 1 von 1 m Länge meist in Polyesterbeton vorfabriziert sind. Diese Rinnenelemente 1 bestehen aus einer Bodenwand 4, die auf ihrer Innenfläche 7 gewölbt und auf ihrer Aussenfläche 8 eben ausgebildet ist. Beidseits dieser Bodenwand 4 ragen Seitenwäne 2, 3 nach oben, die im wesentlichen senkrecht auf der Aussenfläche 8 stehen. Die Stirnseiten der Seitenwände 2, 3 bilden an der verbreiterten Aussenpartie je eine längsverlaufende Rippe 5 und nach innen gerichtete, an diese Rippen 5 anschliessende horizontale Schulterflächen 6.Fig. 1 shows a drainage channel in a generally known embodiment, which are usually prefabricated as channel elements 1 of 1 m in length in polyester concrete. These channel elements 1 consist of a bottom wall 4 which is curved on its inner surface 7 and is flat on its outer surface 8. On both sides of this bottom wall 4, side walls 2, 3 project upwards, which are essentially perpendicular to the outer surface 8. The end faces of the side walls 2, 3 each form a longitudinal rib 5 on the widened outer part and inward horizontal shoulder surfaces 6 adjoining these ribs 5.

Auf diesen Schulterflächen 6 liegt eine Profilplatte 10 auf, die seitliche Stützwände 11 hat, die an den Rippen 5 des Rinnenelementes 1 anliegen und so einen Schutz für die Rippen 5 bilden, aber auf denen auch ein weichelastisches Randelement 20 aufliegt. Zur Halterung dieses Randelementes dient eine profilierte Rippe 12 mit aufrecht stehendem Steg 14 und einer horizontalen Halteschiene 15. Im Randelement 20 gibt es eine gegengleiche Nut 21, so dass das weichelastische Randelement 20 auf das Halteelement 12 angestülpt werden kann. Wie Fig. 1 deutlich zeigt, ist die Höhe der Stützwand 11 und die Dicke des Randelementes 20 über der Stützwand 11 wenigstens angenähert gleich hoch wie die Höhe der Rippe 5 über der Schulter 6.On these shoulder surfaces 6 there is a profile plate 10, which has lateral support walls 11, which bear against the ribs 5 of the channel element 1 and thus form a protection for the ribs 5, but on which there is also a soft elastic edge element 20. A profiled rib 12 with an upright web 14 and a horizontal holding rail 15 is used to hold this edge element. In the edge element 20 there is an opposite groove 21, so that the soft-elastic edge element 20 can be put onto the holding element 12. As clearly shown in FIG. 1, the height of the support wall 11 and the thickness of the edge element 20 above the support wall 11 are at least approximately the same height as the height of the rib 5 above the shoulder 6.

Die Profilplatte 10 hat am Rand in der Stützwand 11 einen Ausschnitt 19, der auch in Fig. 3 mit strichlierter Linie dargestellt ist. Dieser Ausschnitt 19 dient zum Einstecken eines Stabes oder dgl. zum Herausheben des Randelementes 20.The profile plate 10 has at the edge in the support wall 11 a cutout 19, which is also shown in Fig. 3 with a dashed line. This cutout 19 is used for inserting a rod or the like. For lifting out the edge element 20.

Die Profilplatte 10 ist überdies auf ihrer ganzen Länge mit Wasserablaufschlitzen 13 versehen wie sie auch in Fig. 3 und 5 ersichtlich sind.The profile plate 10 is also provided over its entire length with water drainage slots 13 as can also be seen in FIGS. 3 and 5.

In Fig. 1 ist die Profilplatte 10 mit beidseits angeordneten Stützwänden 11 versehen. Selbstverständlich könnte in diesem Fall auch nur einseitig eine Stützwand 11 vorgesehen sein, nämlich als Auflage für das einerseits gezeigte Randelement 20.In Fig. 1, the profile plate 10 is provided with support walls 11 arranged on both sides. In this case, of course, a support wall 11 could also be provided on one side only, namely as a support for the edge element 20 shown on the one hand.

In einer weiteren Ausbildung sind beidseits Randelemente 20 vorhanden, die beide identisch ausgebildet sind und je mittels eines Halteelementes 12 lösbar befestigt sind. Die Halteelemente 12 können ebenfalls wie oben beschrieben, mit Steg 14 und horizontaler Halteschiene 15 ausgebildet sein.In a further embodiment, edge elements 20 are provided on both sides, both of which are of identical design and are each detachably fastened by means of a holding element 12. The holding elements 12 can also be designed, as described above, with a web 14 and a horizontal holding rail 15.

In der Draufsicht gemäss Fig. 3 sind an den beiden Rändern die Rippen 5 der Entwässerungsrinne 1 erkennbar. Die Stützwände 11 der Abdeckplatte 10 sind durch die beiden Randelemente 20 überdeckt und daher nicht ersichtlich. Deutlich sind jedoch die Wasserablaufschlitze 13 ersichtlich.3, the ribs 5 of the drainage channel 1 can be seen on the two edges. The support walls 11 of the cover plate 10 are covered by the two edge elements 20 and are therefore not visible. However, the water drainage slots 13 are clearly visible.

Dadurch, dass die Randelemente 20 die Rippen 5 nicht überstehen, kann auch das Wasser der angrenzenden Flächen gut abfliessen und die Entwässerungsrinnen können ihren Dienst erfüllen.Because the edge elements 20 do not protrude from the ribs 5, the water of the adjacent surfaces can also do well drain and the drainage channels can do their job.

Eine weitere Ausführungsform ist in Fig. 4 und 5 dargestellt. Die Profilplatte 10 weist links in der Zeichnung eine Stützwand 11, wie in Fig. 1 dargestellt, auf und ist ebenso mit einem Randelement 20, wie dort beschrieben, versehen. Rechts in der Zeichnung bildet die Profilplatte 10 ein Stützprofil 16, das eine geringere Breite als die halbe Breite der Profilplatte 10 hat. Dieses Stützprofil 16 hat die Form eines liegenden, quadatischen Prismas und weist in der oberen, der Profilplatte 20 gegenüberliegenden Wand 17 einen Längsschlitz 18 auf.Another embodiment is shown in FIGS. 4 and 5. The profile plate 10 has a support wall 11 on the left in the drawing, as shown in FIG. 1, and is also provided with an edge element 20, as described there. On the right in the drawing, the profile plate 10 forms a support profile 16, which has a smaller width than half the width of the profile plate 10. This support profile 16 has the shape of a lying, square prism and has a longitudinal slot 18 in the upper wall 17 opposite the profile plate 20.

Ein Schutzelement 22 mit Hohlkammern 24 und einer Halterippe 23 mit Steg 25 und Haltewulst 26 dient zum Haltern des Schutzelementes 22 auf dem Stützprofil 16. Zwischen dem Stützprofil 16 und dem Randelement 20 gibt es einen Abstand, in welchem Gebiet wieder die Wasserablaufschlitze 13 angeordnet sind.A protective element 22 with hollow chambers 24 and a holding rib 23 with web 25 and retaining bead 26 serves to hold the protective element 22 on the support profile 16. There is a distance between the support profile 16 and the edge element 20, in which area the water drainage slots 13 are again arranged.

Anstelle der durchgehenden Rippen 12 der Profilplatte 10 oder der Rippen 23 an den Schutzelementen 22 könnten auch pilzförmige Zapfen vorgesehen sein, so dass sie wie die männlichen Teile von Druckknöpfen in der Bekleidungsindustrie aussehen und funktionieren. Vorteilhafterweise bestehen die Randelemente und die Schutzelemente aus einem Kautschuk mit einer Shore-Härte von A75. Sie können je nach der Verwendungsart grün oder rot für den rasenseitigen Abschluss und z.B. weiss für die Laufbahnseite gefärbt sein. Die Profilplatte kann beispielsweise ein Aluminiumprofil sein, es wäre aber auch denkbar einen stabilen und belastbaren Kunststoff zu verwenden.Instead of the continuous ribs 12 of the profile plate 10 or the ribs 23 on the protective elements 22, mushroom-shaped pins could also be provided, so that they look and function like the male parts of push buttons in the clothing industry. The edge elements and the protective elements advantageously consist of a rubber with a Shore hardness of A75. Depending on the type of use, they can be colored green or red for the lawn-side finish and, for example, white for the track side. The profile plate can be an aluminum profile, for example, but it would also be conceivable to use a stable and resilient plastic.
