Description

Die Erfindung betrifft ein Unterhaltsfahrzeug zur Instandstellung des Naturrasenfeldes einer Sportanlage mit einer Wasseraufnahmeeinrichtung zum Abführen von auf dem Rasenfeld angesammeltem Wasser.The invention relates to an maintenance vehicle for the maintenance of the natural grass field a sports facility with a water intake device for draining on the Lawn field of accumulated water.

Bei grossen Sportanlässen, insbesondere Fussballmätchen, kommt es immer wieder vor, dass diese kurz vor Spielbeginn abgesagt werden müssen, weil heftige Regenfällle dazu führen, dass die in offenen Stadien befindlichen Spielfelder vom Regenwasser überflutet werden und die im Rasen eingebauten Kanalisationen nicht mehr im Stande sind, das Wasser aufzunehmen und die Felder demzufolge zumindest teilweise regelrecht überschwemmt sind. Häufig werden dann Fussballspiele eben trotzdem durchgeführt, jedoch nicht mehr unter regulären Spielverhältnissen. Für einen organisierenden Verein kann ein kurz vor Beginn zu verschiebendes oder auch ein abgebrochenes Spiel nebst verärgerten Zuschauern mit erheblichem Kostenaufwand verbunden sein.At big sporting events, especially soccer girls, it always happens that these must be canceled shortly before the start of the game because of heavy rainfall cause the playing fields in open stadiums to be flooded with rainwater and the sewers installed in the lawn are no longer able to To absorb water and consequently at least partially flooded the fields are. Football games are then often played anyway, however no longer under regular playing conditions. For an organizing association one can to be postponed shortly before the start or an aborted game and angry Viewers are associated with considerable costs.

Um diesem Problem abzuhelfen wurden Wasseraufnahmeeinrichtungen vorgeschlagen, z.B. in DE-A-2 025 943, EP-A-0 120 656, DE-A-1963 300 und CH-A-471 935, welche eine Teilentwässerung erlauben.To alleviate this problem, water intake devices have been proposed e.g. in DE-A-2 025 943, EP-A-0 120 656, DE-A-1963 300 and CH-A-471 935, which a Allow partial drainage.

Leider ist das Resultat nicht völlig befriedigend und vermag Folgeschäden an den Sportanlagen nicht zu vermeiden.Unfortunately, the result is not entirely satisfactory and may cause consequential damage to the sports facilities can not be avoided.

Der vorliegenden Erfindung hat man daher die Aufgabe zugrundegelegt, mittels einer neuartigen Einrichtung am Unterhaltsfahrzeug ein Rasenfeld derart herzurichten, dass auf ihm bei jeder Witterung reguläre Spiel oder Veranstaltungen, insbesondere Fussballspiele, durchführbar sind und darüber hinaus gleichzeitig ein schonendes Pflegen des empfindlichen Rasens ermöglicht wird. The present invention is therefore based on the object, by means of a new facility on the maintenance vehicle to prepare a lawn in such a way that provide him with regular games or events in any weather, especially football matches, are feasible and at the same time gentle maintenance of the sensitive lawn.

Die Aufgabe ist erfindungsgemäss durch die Merkmale des Anspruchs 1 gelöst.According to the invention, the task is characterized by the features of Claim 1 solved.

Mit dem erfindungsgemässen Unterhaltsfahrzeug lassen sich Naturrasenfelder so vorbereiten, dass allen voran Fussballspiele inskünftig praktisch bei jeder Witterung durchführbar sind und somit kann verhindert werden, dass kurzfristig Spiele abgesagt werden müssen, Zuschauer vergeblich anreisen und dass unnötige Kostenaufwendungen für einen organisierenden Verein entstehen.With the maintenance vehicle according to the invention, natural grass fields can be prepared that above all football games can be practically carried out in any weather in the future are and thus can be prevented that games are canceled at short notice must, viewers arrive in vain and that unnecessary costs for an organizing association arise.

Das erfindungsgemässe Unterhaltsfahrzeug weist neben der Wasseraufnahmeeinrichtung und dem Vertikulieraggregat, vorzugsweise noch eine Oberflächenwalze und eine Warmluftblaseinrichtung auf. Dadurch kann ein Naturrasen eines Spielfeldes je nach Bedarf mit einem minimalen Aufwand in den optimalen Zustand gebracht werden.The maintenance vehicle according to the invention has in addition to the water intake device and the verticulating unit, preferably also a surface roller and a warm air blowing device. This means that a natural turf on a field can vary Needs to be brought into the optimal condition with minimal effort.

Das Unterhaltsfahrzeug 10 soll derart leistungsstark ausgebildet sein, dass mit ihm anfallendes Regenwasser innert kürzester Zeitdauer von einem Spielfeld entfernt werden kann. Dies richtet sich je nach Menge zwischen 30 und 120 Minuten. Dieses Unterhaltsfahrzeug 10 eignet sich daher speziell, unmittelbar vor dem Spielbeginn oder während einer Spielunterbrechung eingesetzt zu werden und es kann beispielsweise bei starkem Regenfall auch während des Spiels vor und in der Pause eingesetzt werden.The maintenance vehicle 10 should be of such high performance that that rainwater accumulating with it within a very short period of can be removed from a field. This depends on the amount between 30 and 120 minutes. This maintenance vehicle 10 is suitable therefore special, immediately before the start of the game or during a Game interruption to be used and it can for example in case of heavy rain even during the game before and during the break be used.

Das Unterhaltsfahrzeug 10 ist mit einem Vertikulieraggregat 32, vorzugsweise mit einer Oberflächenwalze 34 sowie einer Warmluftblaseinrichtung 50 ausgerüstet. Das Vertikulieraggregat 32 und die Oberflächenwalze 34 sind unterhalb des Fahrzeuges 10 zwischen den Rädern 12 angeordnet und dabei in einer hydraulisch höhenverstellbaren Halterung 33 drehbar gelagert. In der gezeigten Stellung sind diese von der Halterung 33 auf den Boden gepresst. Das Vertikulieraggregat 32 hat eine von einem Antrieb gedrehte Schlitzwalze 35 mit messerartigen Schneiden 38, welche in den Boden eindringen und eine Belüftung desselben auf an sich bekannte Art und Weise erlauben. Diese Schlitzwalze 35 und die parallel zu ihr angeordnete Oberflächenwalze 34 erstrecken sich annähernd über die Fahrzeugbreite und drehen sich beim Fortbewegen des Fahrzeuges, wobei mit der Walze 34 Bodenunebenheiten ausgeglichen werden. Wenn diese beiden Einrichtungen nicht benutzt werden, können sie über eine nicht näher gezeigte Hebevorrichtung vom Boden abgehoben werden.The maintenance vehicle 10 is equipped with a scarifier 32, preferably with a surface roller 34 and a warm air blowing device 50 equipped. The verticalizing unit 32 and the surface roller 34 are below the vehicle 10 between the wheels 12 and arranged in a hydraulically height adjustable Bracket 33 rotatably mounted. In the position shown, these are from the bracket 33 pressed onto the floor. The verticalizing unit 32 has a slit roller 35 rotated by a drive with knife-like Cutting 38, which penetrate the ground and ventilation allow the same in a manner known per se. This Slit roller 35 and the surface roller arranged parallel to it 34 extend approximately across the vehicle width and rotate when moving the vehicle, with the roller 34 Uneven floors are compensated for. If these two bodies can not be used, they can not be specified shown lifting device are lifted off the ground.

Die Warmluftblaseinrichtung 50 ist im hinteren Bereich des Fahrzeuges 10 angeordnet und besteht im wesentlichen aus einer Lufterwärmungsanlage 52 und einem mit dieser gekoppeltem Warmluftgebläse 54, aus welchem Warmluft aus seiner gegen den Boden gerichteten Auslassöffnung 54' herausströmt und somit eine Trocknung des Rasenfeldes bewirkt. Diese Öffnung 54' erstreckt sich vorteilhaft ebenfalls über die Fahrzeugbreite.The hot air blowing device 50 is in the rear area of the vehicle 10 arranged and consists essentially of an air heating system 52 and a hot air blower 54 coupled therewith what warm air from its outlet opening directed towards the floor 54 'flows out and thus dries the lawn causes. This opening 54 'advantageously also extends over the Vehicle width.

Diese Warmluftblaseinrichtung 50 trägt mit dazu bei, dass ein Fussballterrain innert kürzester Zeit in einen optimalen Zustand gebracht werden kann. Fernerhin kann mit dieser auch Schnee oder Eis geschmolzen und somit momentan ein schneefreier und annähernd trockener Rasen herbeigeführt werden. Zu beachten ist dabei, dass die Warmluft eine solche Temperatur aufweist, dass dem Rasen nicht Verbrennungsschäden zugefügt werden.This warm air blowing device 50 contributes to the fact that a Football terrain in optimal condition within a very short time can be brought. Furthermore, it can also be used for snow or ice melted and thus currently a snow-free and almost dry lawn can be brought about. It should be noted that the Warm air has such a temperature that the lawn does not Burn damage can be inflicted.

Die vier Räder 12 des Fahrzeuges 10 sind einzeln über Differentiale angetrieben und mit weichen profillosen Breitpneus ausgestattet, welche beispielsweise eine Breite zwischen 0.30 und 0.80 Metern aufweisen, wie die Fig.2 zeigt. Zweckmässigerweise wird das von diesen einzelnen Rädern 12 auf das Spielfeld 11 wirkende Gewicht pro Flächeneinheit so gewählt, dass es dasjenige einer normalen Person nicht übersteigt.The four wheels 12 of the vehicle 10 are individually via differentials driven and equipped with soft treadless wide tires, which for example, have a width between 0.30 and 0.80 meters, as Fig.2 shows. This is conveniently done by these individuals Wheels 12 on the playing field 11 weight per unit area so chosen that it does not exceed that of a normal person.

Es könnte hinten am Fahrzeug ein Sand- oder ein Samenstreuer montiert werden. Zudem könnte eine Einrichtung im Fahrzeug vorgesehen sein, mittels der Spielfeldbegrenzungen gezeichnet werden könnten. Daraus resultiert eine universelle Gebrauchsmöglichkeit dieses Fahrzeuges 10. Es verfügt überdies über einen Motor, der zum Beispiel mit Propangas betrieben wird. Zur Betätigung des hebbaren Trägers 30 wie auch der Halterung 33 muss ein Hydraulikaggregat vorgesehen sein, welches wie auch der Motor nicht im Detail veranschaulicht sind, jedoch in an sich bekannter Art gebaut sind.There could be a sand or seed spreader on the back of the vehicle to be assembled. It could also be a device in the vehicle be provided, are drawn by means of the field boundaries could. This results in a universal use of this Vehicle 10. It also has an engine, for example is operated with propane gas. For actuating the liftable carrier 30 as well as the holder 33, a hydraulic unit must be provided which, like the engine, are not illustrated in detail, but are built in a manner known per se.

Fig.3 zeigt ein alternatives erfindungsgemässes Fahrzeug 60, das an sich ähnlich demjenigen nach der Fig. aufgebaut ist und daher im folgenden nurmehr die Unterschiede näher erläutert sind. Es verfügt wiederum über ein Vertikulieraggregat 32, eine Oberflächenwalze 34 sowie über eine Warmluftblaseinrichtung 50. Ferner ist im vorderen Teil des Fahrzeuges 60 ein andeutungsweise veranschaulichter Motor 66 integriert.3 shows an alternative vehicle 60 according to the invention is constructed similar to that of the Fig. and therefore in the following only the differences are explained in more detail. It has again via a verticalizing unit 32, a surface roller 34 as well as a warm air blowing device 50. Furthermore, in the front part of the vehicle 60 is an engine 66, which is illustrated as an indication integrated.

Gemäss der Fig.4 ist ein zweiteiliges Chassis 61, 62 des Fahrzeuges 60 vorgesehen, bei welchem die beiden Chassisteile 61, 62 über eine Gelenkverbindung 63 aneinander gehalten sind. Diese Gelenkverbindung 63 bildet eine zum Boden des Spielfeldes 11 senkrecht verlaufende Schwenkachse und ermöglicht eine beschränkte Schwenkbewegung des vorderen gegenüber dem hinteren Chassisteil 61, 62, dadurch die Wendbarkeit des Fahrzeuges 60 verbessert und damit die Rasenfläche geschont wird, insbesondere dann, wenn mit der als Wasseraufnahmeeinrichtung ausgebildeten Saugwalze 80 gearbeitet wird.4 is a two-part chassis 61, 62 of the vehicle 60 provided, in which the two chassis parts 61, 62 via a Hinge connection 63 are held together. This articulation 63 forms a perpendicular to the floor of the playing field 11 Swivel axis and allows a limited swivel movement the front compared to the rear chassis part 61, 62, thereby improving the maneuverability of the vehicle 60 and thus the Lawn area is protected, especially if with the as Water absorption device trained suction roller 80 worked becomes.

Die als Wasseraufnahmeeinrichtung ausgebildete Saugwalze 80 umfasst gemäss Fig.5 bis Fig.7 im wesentlichen eine trommelförmige Walze 85 mit einem Schaumgummiüberzug 90, eine achsparallel zur Walze 85 angeordnete und auf dieser liegende drehbare Gewichtsrolle 87, eine die Walze 85 über Naben 82 drehbar lagernde Achse 81 sowie eine von letzterer gehaltene stationäre Auffangwanne 88, deren Öffnung 88' sich innerhalb der Walze 85 annähernd über deren gesamte Länge und über eine in etwa deren Innendurchmesser entsprechende Breite erstreckt. Die Öffnung 88' ist dabei vorzugsweise oberhalb der Drehachse der Walze 85 in horizontaler Ausrichtung ausgebildet und der Boden der Wanne 88 ist unmittelbar über der unteren Rundung der Walze 85 angeordnet. Die Achse 81 und damit auch die Walze 85 sind beidseitig an je einer auf der Unterseite der Fahrzeugkabine 15 quer angeordneter Blattfeder 94 festgehalten, durch welche die Walze 85 mit einer Federkraft gegen den Boden des Spielfeldes gedrückt wird und mit ihr Bodenunebenheiten ausgeglichen werden können. Diese Blattfedern 94 sind zu diesem Zwecke jeweils beiden Endes und überdies auf der einen Endseite zur Aufnahme ihrer Längenausdehnung um einen Hebel 96 gelenkig gelagert. Die trommelförmige Walze 85 ist perforiert und hat daher über den gesamten Mantel verteilte Löcher 86. Der Schaumgummiüberzug 90 seinerseits ist von einer netzartigen Textilhaut 91 ummantelt und dadurch geschützt. Die Gewichtsrolle 87 erstreckt sich annähernd über die gesamte Länge der Walze 85, ist beidseitig je an einem am Fahrzeug 60 schwenkbar gelagerten Hebel 83 drehbar gehalten und drückt durch ihr Eigengewicht auf den Schaumgummiüberzug 90, welcher im vorliegenden Ausführungsbeispiel eine Dicke von cirka 4 Zentimetern aufweist, jedoch auch mit einer grösseren oder kleineren Wandstärke versehen sein könnte. Das Gewicht der Gewichtsrolle 87 und die Konsistenz des Schaumgummis sind dabei derart aufeinander abgestimmt, dass das vom Boden beim Drehen der Walze schwammartig aufgesaugte Wasser in optimaler Weise ausgepresst wird. Das auf der oberen Seite der Walze 85 ausgepresste Wasser 92 fällt aufgrund der Schwerkraft durch die Löcher 86 in die Auffangwanne 88. Dort wird es zwecks Entleerung der Wanne 88 von einer strichpunktiert gezeigten Leitung 93 in einen im Fahrzeug 60 enthaltenden Wassertank geführt. Dadurch kann sehr schnell eine grosse Menge Wasser aufgesaugt und gesammelt werden.The trained as a water absorption device Suction roller 80 essentially comprises one according to FIGS. 5 to 7 drum-shaped roller 85 with a foam rubber coating 90, one Axially parallel to the roller 85 and rotatable lying thereon Weight roller 87, a roller 85 rotatably mounted on hubs 82 Axis 81 and a stationary drip pan held by the latter 88, the opening 88 'approximately within the roller 85 over their entire length and over an approximately their inner diameter corresponding width extends. The opening 88 'is there preferably horizontally above the axis of rotation of the roller 85 Alignment formed and the bottom of the tub 88 is immediate arranged above the lower curve of the roller 85.
