Description

Die Erfindung betrifft einen Regner mit einer drehbaren Düsenanordnung und einer veränderlich einstellbaren Strahlform der Düsenanordnung.The invention relates to a sprinkler having a rotatable nozzle arrangement and a variably adjustable jet shape of the nozzle arrangement.

Zur Beregnung von Rasenflächen sind u. a. Kreisregner oder Sektorenregner bekannt, welche eine Düsenanordnung enthalten, die um eine im Betrieb im wesentlichen vertikale Drehachse drehbar ist. Die Drehung der Düsenanordnung erfolgt typischerweise mittels einer wasserbetriebenen Antriebseinrichtung, wobei die Drehbewegung auch mit abwechselndem Drehsinn zwischen zwei einstellbaren Winkelgrenzen erfolgen kann.For irrigation of lawns are u. a. Circular sprinklers or sector sprinklers are known, which include a nozzle assembly which is rotatable about a substantially vertical axis of rotation in operation. The rotation of the nozzle arrangement is typically carried out by means of a water-driven drive device, wherein the rotational movement can also take place with an alternating direction of rotation between two adjustable angle limits.

Neben Düsenanordnungen mit bei der Drehung konstanter Strahlform und zur Veränderung der Strahlform, insbesondere zur Veränderung der Beregnungsweite auswechselbarer Düsenanordnung sind auch Regner bekannt, bei welchen die von der Düsenanordnung erzeugte Strahlform während der Drehung der Düsenanordnung in Abhängigkeit vom Drehwinkel veränderbar ist. Der Benutzer kann eine gewünschte Abhängigkeit der Strahlform, insbesondere der Beregnungsweite in einer Einstellphase vorgeben und auch nachträglich verändern und die Düsenanordnung wird im regulären Regnerbetrieb mittels einer Steuereinrichtung nach der vom Benutzer zuvor vorgegebenen Abhängigkeit gesteuert. Die winkelabhängige Steuerung der Düsenanordnung kann z. B. mittels elektrischer Stellmittel erfolgen, wofür in einer elektronischen Steuereinrichtung ein vom Benutzer definierbarer Steuerungsablauf als digitales Steuerprogramm einprogrammierbar ist. Ohne elektronische Steuereinrichtung sind insbesondere Regneranordnungen bekannt, bei welchen eine vom Benutzer mechanisch veränderlich einstellbare Steuerkurve im Regnerbetrieb von einem Steuerelement mechanisch abgefahren und der Steuerkurvenverlauf mechanisch auf die Düsenanordnung übertragen wird. Eine Veränderung der Strahlform kann insbesondere durch Einschwenken eines Deflektorelements in den Strahlverlauf nach einer Düsenöffnung, durch Verändern des Austrittswinkels einer Düsenöffnung, durch Verändern der Durchflussmenge oder Kombinationen solcher Maßnahmen erzielt werden. Als Parameter der Strahlform ist insbesondere die Beregnungsweite eines den gesamten Radius von der Regnerposition bis zur eingestellten Beregnungsweite beregnenden Beregnungsstrahls von Bedeutung, wobei unter einem Beregnungsstrahl in diesem Sinne auch mehrere von einer Düsenanordnung aus mehreren Düsenöffnungen gleichzeitig abgegebene Einzelstrahlen verstanden seien.In addition to nozzle arrangements with a constant-angle beam shape and for changing the jet shape, in particular for changing the irrigation width exchangeable nozzle arrangement, sprinklers are also known in which the jet shape generated by the nozzle assembly is variable during the rotation of the nozzle assembly in dependence on the rotation angle. The user can set a desired dependence of the beam shape, in particular the irrigation width in a setting phase and also subsequently change and the nozzle assembly is controlled in the regular sprinkler operation by means of a control device according to the user previously predetermined dependence. The angle-dependent control of the nozzle arrangement can, for. Example by means of electrical adjusting means, for which in an electronic control device a user-definable control sequence is programmed as a digital control program. Without electronic control device particular sprinkler arrangements are known in which a mechanically variable adjustable by the user control cam in sprinkler mode mechanically driven by a control and the cam profile is mechanically transferred to the nozzle assembly. A change in the beam shape can be achieved in particular by pivoting a deflector element in the beam path after a nozzle opening, by changing the exit angle of a nozzle opening, by changing the flow rate or combinations of such measures. As a parameter of the beam shape, in particular, the irrigation width of a sprinkling jet covering the entire radius from the sprinkler position to the set irrigation width is of importance, wherein a sprinkling jet in this sense also means a plurality of individual jets emitted simultaneously by a nozzle arrangement comprising a plurality of nozzle openings.

Die Vorgabe eines gewünschten Ablaufs der winkelabhängigen Beregnungsweite erfolgt typischerweise in einem Einstellzyklus, in welchem die Düsenanordnung wie im regulären Regnerbetrieb durch die Antriebseinrichtung um die Drehachse gedreht wird und der Benutzer die Beregnungsweite visuell kontrolliert und winkelabhängig erforderlichenfalls verändert. Hierfür ist es in der Regel erforderlich, die Drehung des Regnerkopfes anzuhalten, bis in der dabei eingenommenen Drehwinkelstellung die Beregnungsweite auf den gewünschten Wert eingestellt ist. Die Düsenanordnung bzw. ein die Düsenanordnung enthaltender Regnerkopf kann dabei vom Benutzer von Hand angehalten werden, wofür aber eine nicht unerhebliche Handkraft erforderlich ist. Soweit eine Antriebseinrichtung eine Überlastkupplung enthält, welche in einer solchen Situation anspricht, besteht die Gefahr einer frühzeitigen Abnützung von betroffenen Antriebselementen. Der Benutzer kann auch die aktuell gewählte Beregnungsweite aus seiner für das Anhalten der Drehung der Düsenanordnung notwendigen Perspektive allein nur unzureichend visuell überprüfen.The specification of a desired course of the angle-dependent irrigation width is typically carried out in a setting cycle in which the nozzle assembly is rotated about the axis of rotation by the drive means as in regular sprinkler operation and the user visually controls the irrigation width and modifies it as necessary depending on the angle. For this purpose, it is usually necessary to stop the rotation of the sprinkler head until the irrigation angle is set to the desired value in the angular position taken thereby. The nozzle assembly or a sprinkler head containing the nozzle assembly can be stopped by the user by hand, for which, however, a not inconsiderable manual force is required. As far as a drive device contains an overload clutch, which responds in such a situation, there is the danger of premature wear of affected drive elements. The user alone can not sufficiently visually inspect the currently selected irrigation width from its perspective necessary for stopping the rotation of the nozzle assembly.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, bei einem Regner mit veränderlich einstellbarer winkelabhängiger Strahlform, insbesondere winkelabhängiger Beregnungsweite die Handhabung in der Einstellphase zu verbessern.The present invention is based on the object with a sprinkler with variably adjustable angle-dependent beam shape, in particular angle-dependent Irrigation width to improve handling in the adjustment phase.

Die Erfindung ist im unabhängigen Anspruch beschrieben. Die abhängigen Ansprüche enthalten vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung.The invention is described in the independent claim. The dependent claims contain advantageous refinements and developments of the invention.

Durch die Blockiereinrichtung mit einem mit der Antriebseinrichtung in die Drehung der Düsenanordnung unterbrechend in Eingriff tretenden Blockierelement und mit wenigstens einem manuell betätigbaren Bedienelement zur Verlagerung des Blockierelements zwischen einer Blockierstellung und einer Freigabestellung braucht der Benutzer nur noch das Bedienelement betätigen, wofür eine geringe Betätigungskraft ausreicht. Vorteilhafterweise ist das Blockierelement in der die Drehung der Düsenanordnung unterbrechenden Blockierstellung selbsthaltend mit einer Haltekraft gehalten. Der Benutzer hat dadurch zum einen beide Hände für die Veränderung der Einstellung der Strahlform, insbesondere der Beregnungsweite frei und kann zudem sich auch frei bewegen, um eine visuelle Überprüfung der Beregnungsweite in der angehaltenen Winkelposition vorzunehmen. Die Haltekraft der Blockiereinrichtung ist vorteilhafterweise vom Benutzer manuell überwindbar, um das Blockierelement in die Freigabestellung, in welcher die Drehung der Düsenanordnung freigegeben ist, zurück zu verlagern.By the blocking device with a with the drive device in the rotation of the nozzle assembly intermittently engaging blocking element and at least one manually operable control element for displacement of the blocking element between a blocking position and a release position, the user only needs to operate the control, for which a small operating force is sufficient. Advantageously, the blocking element in the rotation of the nozzle assembly interrupting blocking position is held self-holding with a holding force. The user thereby has both hands free to change the setting of the jet shape, in particular the irrigation width, and can also move freely to make a visual check of the irrigation width in the stopped angular position. The holding force of the blocking device can advantageously be overcome manually by the user in order to shift the blocking element back into the release position in which the rotation of the nozzle arrangement is released.

In einer typischen Ausführung der Antriebseinrichtung mit einem mehrstufigen Getriebe, welches zwischen einer Eingangswelle und einer Ausgangswelle eine Drehzahluntersetzung aufweist, greift das Blockierelement vorteilhafterweise in einer Getriebestufe ein, in welcher nur eine geringe Kraft zum blockieren dieser Getriebestufe und damit auch aller nachfolgenden Stufen erforderlich ist. Bei einem Drehzahluntersetzungsverhältnis n des Getriebes, wobei n als Verhältnis der Drehzahl der Eingangswelle zur Drehzahl der Ausgangswelle im regulären Regnerbetrieb definiert und wesentlich größer als Eins ist, greift das Blockierelement vorteilhafterweise in eine Getriebestufe des Getriebes ein, welche ein Drehzahluntersetzungsverhältnis m als Verhältnis der Drehzahl der Eingangswelle zur Drehzahl der Getriebestufe aufweist, welches maximal gleich der Quadratwurzel aus n ist. Vorzugsweise ist m>1, also die Getriebestufe nicht mit der Eingangswelle identisch.In a typical embodiment of the drive device with a multi-stage transmission, which has a speed reduction between an input shaft and an output shaft, the blocking element advantageously engages in a gear stage in which only a small force is required to block this gear stage and thus also all subsequent stages. At a speed reduction ratio n of the transmission, where n is the ratio Defines the speed of the input shaft to the speed of the output shaft in regular sprinkler operation and is substantially greater than one, engages the blocking element advantageously in a gear stage of the transmission, which has a speed reduction ratio m as the ratio of the speed of the input shaft to the speed of the gear stage, which is equal to the maximum Square root of n is. Preferably, m> 1, ie the gear stage is not identical to the input shaft.

Das Blockierelement kann aber auch direkt auf die Eingangswelle oder über zusätzlich zu dem Getriebe mit der Drehung der Eingangswelle gekoppelte, gegebenenfalls in der Drehzahl reduzierte Elemente indirekt auf die Eingangswelle einwirken. Bei einem Eingriff des Blockierelements direkt mit der Turbine sind Maßnahmen zur Abdichtung zwischen dem Bedienelement und dem im wasserführenden Raum um die Turbine befindlichem Blockierelement zu berücksichtigen, welche bei Eingriff des Blockierelements in einem nicht wasserführenden Bereich entfallen. Beispielsweise kann ein einfach, z. B. über einen O-Ring abzudichtender linear verschiebbarer Stößel, direkt in die Turbine geführt werden. Ein solcher Aufbau ist insbesondere vorteilhaft, wenn der Regner als Unterflurregner ausgeführt ist. Es braucht dann kein offener Getriebebereich abgedichtet werden.The blocking element can also act directly on the input shaft or in addition to the transmission with the rotation of the input shaft coupled, optionally reduced in speed elements indirectly on the input shaft. When the blocking element engages directly with the turbine, measures for sealing between the operating element and the blocking element located in the water-bearing space around the turbine are to be taken into account, which are eliminated when the blocking element engages in a non-water-conducting area. For example, a simple, z. B. be sealed via an O-ring linearly displaceable plunger, are guided directly into the turbine. Such a structure is particularly advantageous when the sprinkler is designed as underfloor sprinkler. It then needs no open gear range to be sealed.

Der Eingriff des Blockierelements in die Antriebseinrichtung kann kraftschlüssig über eine Bremsfläche erfolgen, erfolgt aber vorzugsweise formschlüssig, wofür insbesondere das Blockierelement in eine Verzahnung, insbesondere eine Außenverzahnung eines Zahnrads einer Getriebestufe eingreift und in seiner Ausformung auf eine solche Verzahnung abgestimmt ist. Die Eingriffsrichtung, in welcher das Blockierelement in die Blockierstellung bewegt wird, kann in einfacher Ausführung radial bezüglich der Drehachse eines für den Eingriff eingerichteten Getriebeelements erfolgen, verläuft aber vorteilhafterweise im wesentlichen tangential zu einer Umfangsfläche eines gedrehten Elements der Antriebseinrichtung, mit welchem das Blockierelement in blockierenden Eingriff tritt. Die Bewegung des Blockierelements aus der Blockierstellung in die Freigabestellung kann einem anderen Weg folgen als die Bewegung in die Blockierstellung, ist aber vorzugsweise rein gegenläufig auf gleichem Bewegungsweg.The engagement of the blocking element in the drive device can be frictionally via a braking surface, but preferably takes place positively, for which in particular the blocking element engages in a toothing, in particular an external toothing of a gear of a gear stage and is tuned in its formation to such a toothing. The engagement direction, in which the blocking element is moved into the blocking position, can take place in a simple embodiment radially with respect to the axis of rotation of a meshed gear element, but advantageously extends substantially tangential to a peripheral surface of a rotated member of the drive means with which the blocking member enters into blocking engagement. The movement of the blocking element from the blocking position to the release position may follow a different path than the movement into the blocking position, but is preferably purely in opposite directions on the same path of movement.

Eine tangentiale Bewegung des Blockierelements bei den Verlagerungen zwischen der Blockierstellung und der Freigabestellung ermöglicht vorteilhafterweise auch eine leicht drehende Einwirkung auf die blockierte Getriebestufe und die vor dieser liegenden Getriebestufen, um eine dort z. B. durch ein Sandkorn oder dergleichen aufgetretene Blockierung des Getriebes zu lösen.A tangential movement of the blocking element at the displacements between the blocking position and the release position advantageously also allows a slightly rotating action on the blocked gear stage and lying before this gear stages to a z. B. by a grain of sand or the like occurred blocking the gearbox to solve.

In Fig. 1 ist beispielhaft ein Kreis- oder Sektorenregner mit einem um eine Drehachse DA drehbaren, eine Düsenanordnung DU beherbergenden Regnerkopf RK in teilweise aufgeschnittener Ansicht dargestellt. Der Regnerkopf RK mit der Düsenanordnung DU ist auf einem Regnergehäuse GE um die Drehachse DA drehbar gelagert. Bei auf ebener horizontaler Aufstellfläche aufstehendem Regnergehäuse GE als typischer Betriebsstellung verläuft die Drehachse DA vertikal.In Fig. 1 is an example of a circular or sector sprinkler with a rotatable about a rotational axis DA, a nozzle assembly DU harboring sprinkler head RK shown in partially cutaway view. The sprinkler head RK with the nozzle arrangement DU is rotatably mounted on a sprinkler housing GE about the axis of rotation DA. When standing on a flat horizontal footprint sprinkler housing GE as a typical operating position, the axis of rotation DA runs vertically.

Die Düsenanordnung DU sei um eine Düsenachse VA verschwenkbar, wodurch ein als Strahlbild SB abgegebener Wasserstrahl in seiner Ausstoßrichtung relativ zu der Drehachse DA winkelverstellbar ist, wobei mit der Verstellung der Düsenanordnung DU auch eine Veränderung der Beregnungsweite des Strahlbilds SB einhergeht.The nozzle arrangement DU is pivotable about a nozzle axis VA, whereby a jet of water discharged as jet image SB is angularly adjustable in its ejection direction relative to the axis of rotation DA, with the adjustment of the nozzle arrangement DU also accompanied by a change in the irrigation width of the jet pattern SB.

Auf dem Regnergehäuse GE ist eine die Drehachse DA und den Regnerkopf RK umgebende Steuerkurve SK angeordnet, welche eine Lauffläche LF für ein aus dem Regnerkopf RK seitlich heraus ragendes Ende eines Steuerhebels TH bildet. Die Steuerkurve SK ist an einer Mehrzahl von Abstützungspunkten über Stellhebel SH in ihrer Höhe veränderlich einstellbar, so dass sich typischerweise eine nicht ebene Ringfläche als Lauffläche LF ergibt. Bei im Regnerbetrieb um die Drehachse DA gedrehtem Regnerkopf überträgt der um eine Hebelachse HA schwenkbare Steuerhebel TH Höhenveränderungen der Lauffläche LF der Steuerkurve gegebenenfalls über weitere nicht im einzelnen bezeichnete Hebel auf die um die Düsenachse VA drehbare Düsenanordnung DU, so dass sich in Abhängigkeit von der Drehwinkelposition der Düsenanordnung um die Drehachse DA eine Veränderung der Strahlform, insbesondere eine Veränderung der Beregnungsweite durch das Strahlbild SB ergibt.On the sprinkler housing GE a control axis SK surrounding the axis of rotation DA and the sprinkler head RK is arranged, which forms a running surface LF for a laterally protruding from the sprinkler head RK end of a control lever TH. The control curve SK is variably adjustable in height at a plurality of support points via adjusting lever SH, so that typically results in a non-planar annular surface as tread LF. When in sprinkler operation rotated about the rotation axis DA sprinkler head pivotally about a lever axis HA control lever TH transmits changes in height of the tread LF of the control curve optionally not designated in more detail lever on the rotatable about the nozzle axis VA nozzle assembly DU, so that in dependence on the rotational angular position the nozzle arrangement about the axis of rotation DA results in a change of the beam shape, in particular a change of the irrigation width by the jet pattern SB.

In einer Einstellphase, in welcher die winkelabhängige Steuerung der Düsenanordnung, insbesondere die Beregnungsweite an eine vorgegebene, zu beregnende Fläche angepaßt wird, verstellt der Benutzer die Höhe der Lauffläche LF der Steuerkurve durch Verschwenken der Stellhebel SH um Hebelgelenke HG nach oben oder nach unten. Der mit der Düsenanordnung und dem Regnerkopf RK im Regnerbetrieb mitgedrehte Steuerhebel TH ist vorteilhafterweise auf der dem abgegebenen Wasserstrahl entgegen gesetzten Seite der Drehachse DA angeordnet, so dass der Benutzer bei der Verstellung des jeweils maßgeblichen Stellhebels sich immer in einem nicht von dem Wasserstrahl aktuell betroffenen Bereich befindet.In an adjustment phase, in which the angle-dependent control of the nozzle arrangement, in particular the irrigation width is adapted to a predetermined area to be wetted, the user adjusts the height of the tread LF of the control cam by pivoting the lever SH to lever joints HG up or down. The associated with the nozzle assembly and the sprinkler head RK in sprinkling operation control lever TH is advantageously arranged on the opposite side of the axis of rotation of the dispensed water jet DA, so that the user in the adjustment of each relevant control lever is always in an area not currently affected by the water jet located.

Eine Drehung des Regnerkopfes RK mit Düsenanordnung DU und Steuerhebel TH um die Drehachse DA erfolgt über eine in einem Antriebsgehäuse GG angeordnete Antriebseinrichtung unter der Einwirkung von über einen Wassereinlassanschluss WE zugeführtem und zur Düsenanordnung DU strömenden Wasser, wobei in gebräuchlicher Weise lediglich ein Teil des zur Düsenanordnung DU strömenden Wassers für den Antrieb einer auf der Eingangswelle eines Getriebes angeordneten Turbine benötigt wird und ein weiterer Anteil über eine Bypassleitung an der Turbine vorbei geführt wird.A rotation of the sprinkler head RK with nozzle arrangement DU and control lever TH about the axis of rotation DA via a arranged in a drive housing GG drive means under the action of supplied via a water inlet port WE and flowing to the nozzle assembly DU water, in a conventional manner, only a part of the nozzle assembly DU flowing water is required for driving a arranged on the input shaft of a transmission turbine and another portion is guided over a bypass line to the turbine over.

Die Antriebseinrichtung enthält ein drehzahluntersetzendes Getriebe, welches die hohe Drehzahl der auf der Eingangswelle des Getriebes befestigten Turbine in eine niedrige Drehzahl einer den Regnerkopf relativ zum Regnergehäuse um die Drehachse DA drehenden Ausgangswelle verringert. Bei der skizzierten Ausführung einer Antriebseinheit wird das Antriebsgehäuse GG zusammen mit der Düsenanordnung relativ zu dem Gehäuse GE gedreht. Die Turbine dreht sich im regulären Regnerbetrieb beispielsweise mit 1000 U/min. und die Düsenanordnung dreht sich relativ zum Regnergehäuse GE um die Drehachse DA beispielsweise mit 1 U/min., so dass sich ein Drehzahluntersetzungsverhältnis n = 1000 für das gesamte Getriebe ergibt. Das Getriebe ist typischerweise mehrstufig mit stufenweiser Herabsetzung der Drehzahl aufgebaut. Derartige wasserbetriebene Antriebseinrichtungen in Kreis- oder Sektorenregnern sind seit langem bekannt und gebräuchlich, so dass auf deren Funktion und Aufbau nicht weiter eingegangen wird.The drive means includes a speed reducing gear which reduces the high speed of the turbine mounted on the input shaft of the transmission to a low speed of an output shaft rotating the sprinkler head relative to the sprinkler housing about the axis of rotation DA. In the sketched embodiment of a drive unit, the drive housing GG is rotated together with the nozzle assembly relative to the housing GE. The turbine rotates in regular sprinkler operation, for example, with 1000 rpm. and the nozzle assembly rotates relative to the sprinkler housing GE about the axis of rotation DA, for example at 1 rpm, so that a speed reduction ratio n = 1000 results for the entire transmission. The transmission is typically constructed in multiple stages with gradual reduction of the speed. Such water powered drive devices in circular or sector sprinklers are has long been known and common, so that their function and structure will not be discussed further.

Um dem Benutzer bei den verschiedenen Winkelpositionen der Drehung der Düsenanordnung DU um die Drehachse DA hinreichend Zeit für die präzise Einstellung der gewünschten Beregnungsweite zu geben und/oder mit geringer Handkraft die Drehung der Düsenanordnung zu unterbrechen, ist vorgesehen, dass mittels eines von dem Benutzer betätigbaren Bedienelements BE, welches im skizzierten Beispiel durch eine Aussparung in der Deckelfläche des Regnerkopfes ragt und um eine mit der Drehachse DA zusammen fallende Betätigungsachse um einen begrenzten Winkel verdrehbar ist, eine Weiterdrehung der Düsenanordnung DU um die Drehachse DA vorübergehend blockierbar ist, bis die gewünschte Beregnungsweite hinreichend genau eingestellt ist. In dem nachfolgend noch näher beschriebenen bevorzugten Ausführungsbeispiel ist das Bedienelement BE beispielsweise um ca. 30° um die Drehachse DA zwischen einer in Fig. 1 dargestellten Freigabestellung, in welcher die Düsenanordnung mittels der Antriebseinrichtung um die Drehachse DA gedreht wird, und einer Blockierstellung, in welcher die Weiterdrehung der Düsenanordnung mit dem Steuerhebel TH um die Drehachse DA blockiert ist, verschwenkbar. Die Betätigung des Bedienelements BE wird mittels eines Übertragungselements UE auf ein in Fig. 1 verdeckt liegendes Blockierelement übertragen, welches mit einem Element der Antriebseinrichtung in der Weise zusammen wirkt, dass in einer Freigabestellung die Antriebseinrichtung ungehindert eine Verdrehung der Düsenanordnung um die Drehachse DA bewirkt und dass in einer Blockierstellung das Blockierelement in Eingriff mit einem Element der Antriebseinrichtung steht und eine Bewegung dieses Elementes verhindert und die gesamte Antriebseinrichtung blockiert, so dass die Düsenanordnung ihre Winkelausrichtung um die Drehachse DA beibehält, bis über das Bedienelement BE das Blockierelement wieder außer Eingriff mit dem Element der Antriebseinrichtung gebracht wird und die Antriebseinrichtung die Drehung der Düsenanordnung DU um die Drehachse DA fortsetzt. Während der Blockierung fließt unverändert Wasser von dem Wassereinlass WE durch die Turbine und durch die Bypassleitung zu der Düsenanordnung DU und wird von dieser als Wasserstrahl im Strahlbild SB abgegeben. Die dabei von dem durch die Turbine strömenden Wasser auf die Turbine ausgeübte Kraft wird durch die zwischen Blockierelement und blockiertem Element der Antriebseinrichtung bestehende Kraft kompensiert, so dass die Turbine durchströmt wird, ohne sich zu drehen.To give the user at the various angular positions of the rotation of the nozzle assembly DU about the axis of rotation DA sufficient time for the precise setting of the desired irrigation width and / or to interrupt the rotation of the nozzle assembly with little manual force, it is provided that by means of a user-operable Operating element BE, which projects in the sketched example through a recess in the lid surface of the sprinkler head and about a coincident with the axis of rotation DA actuating axis is rotated by a limited angle, a further rotation of the nozzle assembly DU is temporarily blocked about the axis of rotation DA until the desired irrigation width is set sufficiently accurately. In the preferred embodiment described in more detail below, the operating element BE is, for example, about 30 ° about the axis of rotation DA between a in Fig. 1 illustrated release position in which the nozzle assembly is rotated by the drive means about the rotation axis DA, and a blocking position in which the further rotation of the nozzle assembly is blocked with the control lever TH about the rotation axis DA, pivotable. The actuation of the operating element BE by means of a transmission element UE on a in Fig. 1 transmitted concealed blocking element which cooperates with an element of the drive means in such a way that in a release position, the drive means unhindered causes a rotation of the nozzle assembly about the axis of rotation DA and that in a blocking position, the blocking element is in engagement with an element of the drive means and a Movement of this element prevents and blocks the entire drive means, so that the nozzle assembly maintains its angular orientation about the axis of rotation DA until the operating element BE, the blocking element out of engagement with the Element of the drive device is brought and the drive means continues the rotation of the nozzle assembly DU about the axis of rotation DA. During the blockage, water continues to flow from the water inlet WE through the turbine and through the bypass line to the nozzle assembly DU and is discharged therefrom as a jet of water in the jet pattern SB. The force exerted on the turbine by the water flowing through the turbine is compensated by the force existing between the blocking element and the blocked element of the drive device, so that the turbine is flowed through without turning.

In Fig. 2 bis Fig. 4 ist eine vorteilhafte Ausführung einer Blockiereinrichtung dargestellt. Das Bedienelement BE ist um die Drehachse DA über einen begrenzten Drehwinkel BR drehbar auf einem Düsenträger DT, welcher in Fig. 2 und Fig. 4 ohne die Düsenanordnung DU dargestellt ist, angeordnet.In Fig. 2 to Fig. 4 an advantageous embodiment of a blocking device is shown. The operating element BE is rotatable about the rotational axis DA over a limited angle of rotation BR on a nozzle carrier DT, which is in 2 and FIG. 4 is shown without the nozzle assembly DU arranged.

Von dem Bedienelement BE führt ein starr mit der Drehung des Bedienelements BE verbundenes Übertragungselement UE in Richtung des Gehäuses GG der Antriebseinrichtung. In dem Gehäuse GG ist in einer Seitenwand eine Aussparung GA freigelegt, durch welche die mit einer Außenverzahnung AZ versehene Umfangsfläche eines von mehreren Zahnrädern des Untersetzungsgetriebes zugänglich ist. In der in Fig. 2 dargestellten Freigabestellung der Blockiereinrichtung ist die Außenverzahnung AZ des Zahnrads nicht in Eingriff mit dem in Fig. 2 verdeckt liegenden Blockierelement und die dem Zahnrad zugeordnete Getriebestufe und das gesamte Getriebe daher unter Einwirkung der auf der Eingangswelle befestigten Turbine frei drehbar. Das Zahnrad, dessen Außenverzahnung AZ durch die Aussparung GA zugänglich ist, drehe sich mit einer gegenüber der Eingangswelle um ein Untersetzungsverhältnis n>1 reduzierten Drehzahl.From the operating element BE leads a rigidly connected to the rotation of the operating element BE transmission element UE in the direction of the housing GG of the drive device. In the housing GG, a recess GA is exposed in a side wall, through which the provided with an external toothing AZ circumferential surface of one of a plurality of gears of the reduction gear is accessible. In the in Fig. 2 illustrated release position of the blocking device, the external toothing AZ of the gear is not engaged with the in Fig. 2 concealed blocking element and the transmission gear assigned to the gear and the entire transmission therefore freely rotatable under the action of the turbine mounted on the input shaft. The gear, whose external toothing AZ is accessible through the recess GA, turns with a speed reduced by a reduction ratio n> 1 with respect to the input shaft.

In Fig. 3 ist ein die Aussparung GA mit der Außenverzahnung AZ des Zahnrades umfassender Ausschnitt vergrößert dargestellt, wobei das Übertragungselement UE weitgehend weggelassen ist und lediglich dessen unteres Ende, an welchem das Blockierelement BL ausgebildet ist, dargestellt ist. Das Blockierelement BL besitzt eine zu der Aussparung GA hin weisende Verzahnung BZ, welche auf die über die Aussparung GA zugängliche Außenverzahnung AZ des Zahnrades des Getriebes abgestimmt ausgeformt ist und beispielsweise als ein Bogensegment einer Verzahnung ausgeführt ist. Ein Wandabschnitt RS des Getriebegehäuses bildet gegenüber der Aussparung GA eine Lücke, in welche das Blockierelement bei Betätigung des Bedienelements gedreht werden kann. In Fig. 4 ist in zu Fig. 2 entsprechender Ansicht die Blockiervorrichtung in der Blockierstellung dargestellt, in welcher das Bedienelement BE um die Drehachse DA gegenüber der Freigabestellung nach Fig. 2 verschwenkt ist. Die Blockiereinrichtung ist in dieser Stellung mit einer Haltekraft selbsthaltend, was durch Reibungskraft oder durch Verrastung erfolgen kann. Die Haltekraft ist durch den Benutzer manuell überwindbar, um das Bedienelement wieder in die in Fig. 2 dargestellte Freigabestellung zurück zu schwenken. Es können auch gesonderte Arretiermittel vorgesehen sein, um die Blockiereinrichtung in der in Fig. 4 dargestellten Blockierstellung zu halten, wobei solche Arretiermittel gleichfalls vorzugsweise durch den Benutzer manuell lösbar sind.In Fig. 3 is a recess comprising the recess GA with the external toothing AZ of the gear shown enlarged, wherein the transmission element UE is largely omitted and only the lower end, on which the blocking element BL is formed, is shown. The blocking element BL has a toothing BZ which points toward the recess GA and which is shaped in a coordinated manner with the external toothing AZ of the toothed wheel of the gearbox accessible via the cutout GA and is embodied, for example, as an arc segment of a toothing. A wall section RS of the gear housing forms opposite to the recess GA a gap into which the blocking element can be rotated upon actuation of the operating element. In Fig. 4 is in too Fig. 2 corresponding view, the blocking device shown in the blocking position, in which the operating element BE about the axis of rotation DA relative to the release position to Fig. 2 is pivoted. The blocking device is self-holding in this position with a holding force, which can be done by frictional force or by locking. The holding force is manually overcome by the user to return the control element to the in Fig. 2 swing back shown release position. It may also be provided separate locking means to the blocking device in the in Fig. 4 hold blocking position shown, wherein such locking means are also preferably manually detachable by the user.

In dem in der Darstellung der Fig. 3 entsprechenden vergrößerten Ausschnitt in Fig. 5 zu der Blockierstellung des Blockierelements bzw. des Bedienelements BE nach Fig. 4 ist anschaulich dargestellt, dass das Blockierelement BL nunmehr in die Lücke zwischen dem Wandabschnitt RS des Gehäuses GG und der Außenverzahnung AZ einliegt und dabei die Zahnreihe BZ des Blockierelements BL in formschlüssigem Eingriff mit der Außenverzahnung AZ des Zahnrades steht. Das Zahnrad ist dadurch nicht mehr drehbar und somit das Getriebe und die Drehung der Düsenanordnung DU um die Drehachse DA blockiert. Das Blockierelement BL als unteres Ende des Übertragungselements UE ist durch den Wandabschnitt RS radial abgestützt, so dass der formschlüssige Eingriff der Verzahnungen AZ und BZ zuverlässig erhalten bleibt und das untere Ende des Übertragungselements mit dem Blockierelemente BL nicht unter der Einwirkung der über die weiterhin wasserdurchströmte Turbine auf das Zahnrad ausgeübte Kraft radial nach außen ausweichen kann. Der Wandabschnitt RS bildet ferner eine Führung bei der Verschwenkung des Blockierelements.In the in the presentation of the Fig. 3 corresponding enlarged detail in Fig. 5 to the blocking position of the blocking element or the operating element BE after Fig. 4 is clearly shown that the blocking element BL now rests in the gap between the wall portion RS of the housing GG and the outer toothing AZ and thereby the row of teeth BZ of the blocking element BL is in positive engagement with the external toothing AZ of the gear. The gear is thus no longer rotatable and thus the gear and the rotation of the nozzle assembly DU blocked around the axis of rotation DA. The blocking element BL as the lower end of the transmission element UE is radially supported by the wall section RS, so that the interlocking engagement of the teeth AZ and BZ is reliably maintained and the lower end of the transmission element with the blocking elements BL not under the influence of over the continued water-flow turbine force exerted on the gear can escape radially outward. The wall section RS further forms a guide during the pivoting of the blocking element.

Bei der Verschwenkung des Blockierelements aus der in Fig. 3 dargestellten Freigabestellung in die in Fig. 5 dargestellte Blockierstellung beschreibt das Blockierelement mit der Zahnreihe BZ einen Weg auf einem Kreissegment um die Drehachse DA, um welche das Bedienelement BE verdrehbar ist. Der Radius dieses Kreissegments ist wesentlich größer als der Radius der Außenverzahnung AZ des Zahnrades, so dass die Bewegung des Blockierelementes als tangential bezüglich der durch die Außenverzahnung AZ gebildeten Umfangsfläche des Zahnrads angesehen werden kann.When pivoting the blocking element from the in Fig. 3 shown release position in the in Fig. 5 illustrated blocking position describes the blocking element with the row of teeth BZ a path on a circular segment about the axis of rotation DA, about which the operating element BE is rotatable. The radius of this circle segment is substantially greater than the radius of the external toothing AZ of the gear, so that the movement of the blocking element can be regarded as tangential with respect to the peripheral surface of the gear formed by the external toothing AZ.

Solange sich die Blockiereinrichtung in der in Fig. 4 und Fig. 5 dargestellten Blockierstellung befindet, ist die Weiterdrehung der Düsenanordnung DU um die Drehachse DA blockiert und der Benutzer kann ohne Zeitdruck und ohne die Blockiereinrichtung festhalten zu müssen, die in dieser Ausrichtung der Düsenanordnung von ihm gewünschte Beregnungsweite über die Stellhebel einstellen. Nach erfolgter Einstellung einer gewünschten Beregnungsweite verlagert der Benutzer die Blockiereinrichtung durch Zurückdrehen des Bedienelements BE in die in Fig. 2 dargestellte Freigabestellung und die Antriebseinrichtung setzt die Drehung der Düsenanordnung DA um die Drehachse DA fort. Ein zusätzlicher vorteilhafter Effekt der mehrere Zähne aufweisenden Zahnreihe BZ des Blockierelements BL besteht darin, dass durch Hin- und Herdrehen des Bedienelements BE um einen gegenüber der maximalen Verdrehbarkeit BR kleineren Drehwinkel bei in Blockierstellung befindlichem Blockierelement dem Getriebe gleichfalls eine Bewegung in abwechselnden Richtungen aufgezwungen wird und so bei einer eventuellen Blockierung des Getriebes durch ein Sandkorn oder dergleichen in einer der der Turbine nahen Getriebestufen eventuell auf einfache Weise gelöst werden kann.As long as the blocking device in the in 4 and FIG. 5 Blocking position is shown, the further rotation of the nozzle assembly DU is blocked around the axis of rotation DA and the user can hold without time pressure and without the blocking device, set in this orientation of the nozzle assembly of him desired irrigation width via the lever. After setting a desired irrigation width, the user moves the blocking device by turning back the operating element BE in the in Fig. 2 illustrated release position and the drive means continues the rotation of the nozzle assembly DA about the axis of rotation DA. An additional advantageous effect of the plurality of teeth having row of teeth BZ of the blocking element BL is that by turning back and forth of the control element BE to a smaller than the maximum twistability BR smaller angle of rotation in blocking position befindlichem blocking element the transmission is also forced to move in alternating directions and Thus, in a possible blockage of the transmission by a grain of sand or the like in one of the turbine close gear stages may possibly be solved in a simple manner.
