Description

TECHNISCHES GEBIETTECHNICAL AREA

Die vorliegende Erfindung betrifft eine Ablaufanordnung für die Dachentwässerung umfassend eine Ablaufvorrichtung und eine Einlaufvorrichtung nach dem Oberbegriff von Anspruch 1.The present invention relates to a drain arrangement for roof drainage comprising a drain device and an inlet device according to the preamble of claim 1.

STAND DER TECHNIKSTATE OF THE ART

Aus dem Stand der Technik sind Entwässerungssysteme für Flächen, wie beispielsweise Flachdächer, bekannt. Solche Entwässerungssysteme umfassen dabei ein Rohrsystem, über welches das auf den Flächen liegende Wasser abgeführt wird. Typischerweise herrscht im Rohrsystem ein Unterdruck, welcher für eine schnelle und sichere Entwässerung sorgt.Drainage systems for surfaces such as flat roofs are known from the prior art. Such drainage systems include a pipe system through which the water lying on the surfaces is discharged. Typically, there is a negative pressure in the pipe system, which ensures fast and safe drainage.

Die Anmelderin selbst vertreibt ein solches Entwässerungssystem unter dem Namen Pluvia. EP 2468979 A1 offenbart ferner eine gattungsgemäße Ablaufanordnung mit einer Ablaufvorrichtung und einer Einlaufvorrichtung.The applicant itself sells such a drainage system under the name Pluvia. EP 2468979 A1 also discloses a generic drain arrangement with a drain device and an inlet device.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Ausgehend von diesem Stand der Technik liegt der Erfindung eine Aufgabe zugrunde, eine Ablaufanordnung für Dachentwässerungssysteme anzugeben, welche die Nachteile des Standes der Technik überwindet. Insbesondere soll eine Ablaufvorrichtung angegeben werden, welche möglichst flexibel montierbar ist.Proceeding from this prior art, the object of the invention is to specify a drain arrangement for roof drainage systems which overcomes the disadvantages of the prior art. In particular, a drainage device is to be specified which can be mounted as flexibly as possible.

Diese Aufgabe löst der Gegenstand von Anspruch 1. Demgemäss umfasst eine Ablaufanordnung für die Dachentwässerung eine Ablaufvorrichtung und eine Einlaufvorrichtung. Die Ablaufvorrichtung weist einen Rohrstutzen und mindestens ein Halteelement, das vorzugsweise mit dem Rohrstutzen in Verbindung steht, auf. Das Halteelement könnte auch anderweitig befestigt sein, beispielsweise gebäudeseitig. Die Einlaufvorrichtung umfasst ein Abdeckteil zur Abdeckung des Rohreintritts mit seitlichen Durchgängen, durch welche Wasser zum Rohreintritt zuführbar ist, und zwei Funktionsteile, welche unterhalb des Abdeckteils wahlweise anordbar sind. Eines der Funktionsteile ist ein eine Stauhöhe definierendes Staufunktionsteil und ein anderes der Funktionsteile ist ein Notüberlauffunktionsteil mit einem eine Einlaufhöhe definierenden Einlauf. Sowohl das Staufunktionsteil als auch das Notüberlauffunktionsteil und das Abdeckteil sind zum besagten mindestens einen Halteelement befestigbar.This object is achieved by the subject matter of claim 1. Accordingly, a drain arrangement for roof drainage comprises a drain device and an inlet device. The drain device has a pipe socket and at least one Retaining element, which is preferably connected to the pipe socket, on. The holding element could also be fixed in some other way, for example on the building side. The inlet device comprises a cover part for covering the pipe inlet with lateral passages through which water can be fed to the pipe inlet, and two functional parts which can be optionally arranged below the cover part. One of the functional parts is a storage function part that defines a storage height, and another of the functional parts is an emergency overflow function part with an inlet that defines an inlet height. Both the storage function part and the emergency overflow function part and the cover part can be fastened to said at least one holding element.

Das Halteelement dient also der Aufnahme des Staufunktionsteils und des Abdeckteils bzw. des Notüberlauffunktionsteils und des Abdeckteils. Somit kann die also die Paarung Staufunktionsteils und Abdeckteil und die Paarung Notüberlauffunktionsteil und Abdeckteil am gleichen Halteelement befestigt werden. Diese Ausbildung ist vorteilhaft, weil eine Anpassung der Halteelemente mit Blick auf die Funktion der Ablaufanordnung entfällt.The holding element thus serves to accommodate the accumulation function part and the cover part or the emergency overflow function part and the cover part. Thus, the pairing of storage function part and cover part and the pairing of emergency overflow function part and cover part can be fastened to the same holding element. This design is advantageous because there is no need to adapt the holding elements with regard to the function of the drain arrangement.

Darüber hinaus ergeht auch der Vorteil, dass die Ablaufanordnung flexibler einsetzbar ist.In addition, there is also the advantage that the drain arrangement can be used more flexibly.

So kann der Installateur vor Ort entscheiden, ob die Teile der Ablaufanordnung als Notüberlauf oder als normaler Einlauf eingesetzt werden können.In this way, the installer can decide on site whether the parts of the drain arrangement can be used as an emergency overflow or as a normal inlet.

Vorzugsweise werden sowohl das Staufunktionsteil als auch das Notüberlauffunktionsteil durch das Abdeckteil am Halteelement gehalten. In diesem Fall dient das Abdeckteil als Befestigungsmittel für das Staufunktionsteil und das Notüberlauffunktionsteil zum Halteelement. Es können also zusätzliche Befestigungselemente entfallen.Both the accumulation function part and the emergency overflow function part are preferably held by the cover part on the holding element. In this case, the cover part serves as a fastening means for the storage function part and the emergency overflow function part to the holding element. Additional fastening elements can therefore be omitted.

Besonders bevorzugt sind genau zwei Halteelement bezüglich des Rohrstutzens diametral gegenüber einander angeordnet.Exactly two holding elements are particularly preferably arranged diametrically opposite one another with respect to the pipe socket.

Ein Funktionsteil kann wie erwähnt als Staufunktionsteil oder als Notüberlauffunktionsteil bereitgestellt werden. Das Staufunktionsteil ist dabei unterschiedlich ausgebildet als das Notüberlauffunktionsteil. Identisch ist aber das Abdeckteil in beiden Fällen. Folglich ergeht der Vorteil, dass die Einlaufvorrichtung vielseitig, also mit den beiden Funktionen "normaler Ablauf" und "Notablauf" bereitgestellt werden kann, wobei lediglich das entsprechende Funktionsteil gewählt werden muss.As mentioned, a functional part can function as a backup function part or as an emergency overflow function part to be provided. The accumulation function part is designed differently than the emergency overflow function part. However, the cover part is identical in both cases. Consequently, there is the advantage that the inlet device is versatile, i.e. with the two functions "normal process" and "emergency process" can be provided, with only the corresponding functional part having to be selected.

Besonders bevorzugt stellt das Abdeckteil einen Innenraum bereit, in welchem das Funktionsteil liegt. Der Innenraum ist durch besagten Durchbrüche zugänglich.The cover part particularly preferably provides an interior space in which the functional part is located. The interior is accessible through said breakthroughs.

Erfindungsgemäß verfügt das Staufunktionsteil über mindestens eine Befestigungsschnittstelle zur Befestigung des Staufunktionsteils zum Halteelement und das Notüberlauffunktionsteil verfügt über mindestens eine Befestigungsschnittstelle zur Befestigung des Notüberlauffunktionsteils zum Haltelement. Die besagte Befestigungsschnittstelle des Staufunktionsteils und die Befestigungsschnittstelle des Notüberlauffunktionsteils sind dabei im Wesentlichen identisch zueinander ausgebildet.According to the invention, the storage function part has at least one attachment interface for attaching the storage function part to the holding element and the emergency overflow function part has at least one attachment interface for attaching the emergency overflow function part to the holding element. Said attachment interface of the accumulation function part and the attachment interface of the emergency overflow function part are designed essentially identical to one another.

Unter einer identischen Ausbildung der Befestigungsschnittstelle wird verstanden, dass bei der Anordnung der Halteelemente keine Modifikationen bei wechselnder Befestigung des Staufunktionsteils oder des Notüberlauffunktionsteil nötig ist. Das heisst, bei einer gegebenen Konfiguration der Halteelemente kann sowohl das Staufunktionsteil als auch das Notüberlauffunktionsteil mit den Halteelementen verbunden werden.An identical design of the fastening interface is understood to mean that no modifications are necessary when the retaining elements are arranged when the accumulation function part or the emergency overflow function part is fastened alternately. This means that with a given configuration of the holding elements, both the storage function part and the emergency overflow function part can be connected to the holding elements.

Vorzugsweise weist das Staufunktionsteil und das Notüberlauffunktionsteil einen scheibenförmigen Basisabschnitt auf, wobei im montierten Zustand der scheibenförmige Basisabschnitt des Staufunktionsteil und derjenige des Notüberlauffunktionsteil vorzugsweise auf gleicher Höhe liegen.The accumulation function part and the emergency overflow function part preferably have a disc-shaped base section, with the disk-shaped base section of the accumulation function part and that of the emergency overflow function part preferably being at the same level in the assembled state.

Der Basisabschnitt kann dabei mindestens Teile der Befestigungsschnittstelle umfassen und/oder aufnehmen und/oder bereitstellen.The base section can include and/or accommodate and/or provide at least parts of the fastening interface.

Vorzugsweise weist die Befestigungsschnittstelle des Staufunktionsteils und die Befestigungsschnittstelle des Notüberlaufteils die Gestalt von einer Öffnung auf. Je nach Zahl der Halteelemente können mehrere Öffnungen angeordnet sein. Die Zahl der Halteelemente entspricht vorzugsweise der Zahl der Öffnungen. Die Öffnung bzw. die Öffnungen sind am Staufunktionsteil und am Notüberlauffunktionsteil lagegleich und/oder positionsgleich angeordnet.Preferably, the attachment interface of the accumulation function part and the attachment interface of the emergency overflow part have the shape of an opening. Depending on the number of holding elements, several openings can be arranged. The number of holding elements preferably corresponds to the number of openings. The opening or openings are arranged in the same position and/or in the same position on the accumulation function part and on the emergency overflow function part.

Vorzugsweise ist die Öffnung im scheibenförmigen Basisabschnitt angeordnet. Der scheibenförmige Basisabschnitt kann im Bereich der Öffnung unterschiedlich ausgebildet sein. In einer ersten Ausbildung ist der scheibenförmige Basisabschnitt im Bereich der Öffnung eben ausgebildet. In einer zweiten Ausbildung weist der scheibenförmige Basisabschnitt im Bereich der Öffnung eine Ausbuchtung auf, die sich vom Abdeckteil weg erstreckt, wobei die Öffnung in der Ausbuchtung angeordnet ist. Durch die Ausbuchtung wird die Form des Basisabschnittes verändert, wodurch auch die Form des Haltelementes, das gebäudeseitig montiert wird, verändert werden kann. Ragt die Ausbuchtung beispielsweise Richtung Gebäude, so kann das Halteelement kürzer ausgebildet werden, was bei der Montage bezüglich einer unbeabsichtigten Verformung durch den Installateur vorteilhaft ist. Die Ausbuchtung im Staufunktionsteil ist dabei vorzugsweise identisch zur Ausbuchtung im Notüberlauffunktionsteil ausgebildet.The opening is preferably arranged in the disc-shaped base section. The disc-shaped base section can be designed differently in the area of the opening. In a first embodiment, the disc-shaped base section is flat in the area of the opening. In a second embodiment, the disc-shaped base section has a bulge in the area of the opening, which bulge extends away from the cover part, with the opening being arranged in the bulge. The shape of the base section is changed by the bulge, whereby the shape of the holding element, which is mounted on the building side, can also be changed. If the bulge protrudes in the direction of the building, for example, the holding element can be made shorter, which is advantageous during assembly with regard to unintentional deformation by the installer. The bulge in the storage function part is preferably designed identically to the bulge in the emergency overflow function part.

Vorzugsweise ist mindestens ein Befestigungselement am Abdeckteil verschiebbar gelagert, mit welchem Befestigungselement das Abdeckteil zum Halteelement befestigbar ist. Vorzugsweise ist das Befestigungselement um eine Achse verdrehbar. Die Zahl der Befestigungselemente entspricht bevorzugt der Zahl der Halteelemente. Die Befestigungselemente sind vorzugsweise lagegleich und/oder positionsgleich zu den Öffnungen angeordnet.Preferably, at least one fastening element is displaceably mounted on the cover part, with which fastening element the cover part can be fastened to the holding element. The fastening element can preferably be rotated about an axis. The number of fastening elements preferably corresponds to the number of holding elements. The fastening elements are preferably arranged in the same position and/or in the same position as the openings.

Das Befestigungselement kann einteilig oder mehrteilig ausgebildet sein. In der mehrteiligen Ausbildung umfasst das Befestigungselement ein Aktuatorteil und ein Verriegelungsteil, welche miteinander in Verbindung stehen, wobei das Aktuatorteil mindestens teilweise oberseitig zum Abdeckteil und das Verriegelungsteil mindestens teilweise unterseitig zum Abdeckteil liegt.The fastening element can be designed in one piece or in several pieces. In the multi-part design, the fastening element comprises an actuator part and a locking part which are connected to one another, with the actuator part being at least partially on top of the cover part and the locking part being at least partially on the underside of the cover part.

Vorzugsweise ist das Halteelement als Zapfen mit einer Kerbe, insbesondere einer umlaufenden Rille, ausgebildet, wobei das Abdeckteil, insbesondere mit dem Befestigungselement, über die Kerbe zum Haltelement befestigbar istThe holding element is preferably designed as a pin with a notch, in particular a circumferential groove, it being possible for the cover part to be fastened to the holding element, in particular with the fastening element, via the notch

Vorzugsweise weist das Halteelement eine Lagerfläche auf, auf welcher das Funktionsteil, insbesondere mit der Unterseite des Basisabschnittes abgestützt ist. Die Lagerfläche ist bevorzugt mit einem Abstand zur Kerbe angeordnet, welcher Abstand vorzugsweise der Dicke des Basisabschnittes entspricht.The holding element preferably has a bearing surface on which the functional part is supported, in particular with the underside of the base section. The storage area is preferably arranged at a distance from the notch, which distance preferably corresponds to the thickness of the base portion.

Vorzugsweise verfügen das Funktionsteil und das Abdeckteil über Ausrichtelemente, insbesondere über Ausnehmungen und Erhebungen, wobei über die Ausrichtelemente das Abdeckteil zum Funktionsteil ausrichtbar ist. Vorzugsweise sind am Funktionsteil Ausnehmung angeordnet und die Stege, welche die Durchbrüche am Abdeckteil begrenzen, dienen als Erhebungen.The functional part and the cover part preferably have alignment elements, in particular recesses and elevations, it being possible for the cover part to be aligned with the functional part via the alignment elements. Recesses are preferably arranged on the functional part and the webs, which delimit the openings on the cover part, serve as elevations.

Vorzugsweise umfasst beim Notüberlaufunktionsteil der Basisabschnitt eine den Einlauf bereitstellende Durchlassöffnung und eine sich vom scheibenförmigen Basisabschnitt um die Durchlassöffnung vollständig herum erstreckende Erhebung, deren Oberkante die Einlaufhöhe definiert. Durch die Wahl der Höhe der Erhebung kann die maximale Höhe des Wasserstandes, bis das Wasser über den Notüberlauf abfliessen soll definiert werden.In the case of the emergency overflow function part, the base section preferably comprises a through-opening providing the inlet and an elevation which extends completely around the through-opening from the disc-shaped base section and whose upper edge defines the inlet height. By choosing the height of the elevation, the maximum height of the water level until the water is to flow out via the emergency overflow can be defined.

In Einbaulage liegen der Basisabschnitt des Staufunktionsteils und der Basisabschnitt des Notüberlauffunktionsteils im Wesentlichen auf gleicher Höhe.In the installed position, the base section of the accumulation function part and the base section of the emergency overflow function part are essentially at the same level.

Besonders bevorzugt ist die Erhebung Teil eines Rohrabschnittes, welcher sich von der Oberkante der Erhebung durch den scheibenförmigen Basisabschnitt hindurch erstreckt und in Einbaulage in den Rohreintritt des Ablaufrohrs einragt.The elevation is particularly preferably part of a pipe section, which extends from the upper edge of the elevation through the disk-shaped base section and protrudes into the pipe inlet of the drain pipe in the installed position.

Vorzugsweise ist zwischen der Unterseite des Abdeckteils und der Erhebung ein freier Zwischenraum vorhanden, durch welchen das abzuführende Wasser dem Einlauf des Notüberlauffunktionsteils zuführbar ist.Preferably, there is a free space between the underside of the cover part and the elevation, through which the water to be drained can be fed to the inlet of the emergency overflow functional part.

Vorzugsweise ist das Staufunktionsteil beabstandet zum Rohrstutzen angeordnet, so dass Wasser durch den Abstand in den Rohrstutzen einfliessen kann. Es wird also ein Zwischenraum zwischen dem Staufunktionsteil, insbesondere seinem Basisabschnitt, und dem Rohreintritt geschaffen, über welchen das Wasser einfliessen kann. Bis zum Erreichen des Niveaus des Staufunktionsteils fliesst das Wasser normal mit Luft in den Rohrstutzen ein. Sobald die Stauhöhe überschritten wird, verhindert das Staufunktionsteil weiteres Einfliessen von Luft in den Rohrstutzen, was den Abfluss von Wasser begünstigt. Vorzugsweise ist das Notüberlauffunktionsteil derart zum Rohrstutzen angeordnet ist, dass Wasser ausschliesslich über den Einlauf des Notüberlaufunktionsteil in den Rohrstutzen einfliessen kann. Insbesondere ragt das Rohrstück des Notüberlauffunktionsteil in den Rohrstutzen ein. Zwischen Rohrstück und Rohrstutzen ist vorzugsweise eine Dichtung angeordnet.The storage function part is preferably arranged at a distance from the pipe socket, so that water can flow into the pipe socket through the distance. An intermediate space is thus created between the accumulation function part, in particular its base section, and the pipe inlet, through which the water can flow. Until the level of the accumulation function part is reached, the water flows normally with air into the pipe socket. As soon as the accumulation height is exceeded, the accumulation function part prevents further inflow of air into the pipe socket, which promotes the drainage of water. The emergency overflow function part is preferably arranged relative to the pipe socket in such a way that water can only flow into the pipe socket via the inlet of the emergency overflow function part. In particular, the piece of pipe of the emergency overflow functional part protrudes into the pipe socket. A seal is preferably arranged between the piece of pipe and the pipe socket.

Das Staufunktionsteil dient der Verhinderung eines Lufteintritts in das Ablaufrohr wenn der Wasserstand auf dem Gebäude eine Stauhöhe erreicht bzw. überschritten hat. Das Notüberlauffunktionsteil hat einen eine Einlaufhöhe definierenden Einlauf, wobei durch das Notüberlauffunktionsteil ein Notablauf bei Überschreiten der Einlaufhöhe durch den Wasserstand auf dem Gebäude bereitgestellt wird. Die Stauhöhe des Staufunktionsteils liegt tiefer oder gleich als die Einlaufhöhe des Notüberlauffunktionsteils.The storage function part serves to prevent air from entering the drain pipe when the water level on the building has reached or exceeded a storage level. The emergency overflow function part has an inlet defining an inlet height, with the emergency overflow function part providing an emergency outlet when the water level on the building exceeds the inlet height. The accumulation height of the accumulation function part is lower than or equal to the inlet height of the emergency overflow function part.

Weitere Ausführungsformen sind in den abhängigen Ansprüchen angegeben.Further embodiments are specified in the dependent claims.

BESCHREIBUNG BEVORZUGTER AUSFÜHRUNGSFORMENDESCRIPTION OF PREFERRED EMBODIMENTS

In der Figur 1 wird eine perspektive Ansicht einer Ablaufanordnung 29 gezeigt. Die Ablaufanordnung 29 umfasst eine Ablaufvorrichtung 3 für die Gebäude-Entwässerung und eine Einlaufvorrichtung 1, welche über der Ablaufvorrichtung 3 angeordnet ist. Über die Einlaufvorrichtung 1 wird das abzuführende Wasser der Ablaufvorrichtung 3 zugeführt. Eine derartige in den Figuren gezeigte Ablaufanordnung 29 wird typischerweise in der Gebäude-Entwässerung auf einem Dach angeordnet. Es können aber auch andere Flächen, die nicht Teil eines Gebäudes sein können, entwässert werden. Das Gebäude ist in den Figuren nur symbolisch gezeigt und trägt das Bezugszeichen G.In the figure 1 a perspective view of a drain assembly 29 is shown. The outflow arrangement 29 comprises an outflow device 3 for the building drainage and an inlet device 1 which is arranged above the outflow device 3 . The water to be discharged is fed to the discharge device 3 via the inlet device 1 . Such a drain arrangement 29 shown in the figures is typically arranged in the building drainage on a roof. However, other areas that cannot be part of a building can also be drained. The building is only shown symbolically in the figures and bears the reference symbol G.

Die Figuren 2 und 3 zeigen eine Schnittdarstellung der Ablaufvorrichtung 29. Insbesondere wird die Einlaufvorrichtung 1 genauer gezeigt. Anhand der Figuren 2 und 3 wird nun die Einlaufvorrichtung 1 genauer erläutert.the Figures 2 and 3 show a sectional view of the outlet device 29. In particular, the inlet device 1 is shown in more detail. Based on Figures 2 and 3 the inlet device 1 will now be explained in more detail.

Die Einlaufvorrichtung 1 umfasst ein Abdeckteil 4 zur Abdeckung des Rohreintritts 2 und ein Funktionsteil 5. Das Funktionsteil 5 ist unterhalb des Abdeckteils 4 angeordnet. Das Abdeckteil 4 ist mit einer Vielzahl von seitlichen Durchgängen 21 versehen, durch welche Wasser zur Ablaufvorrichtung 3 zuführbar ist. Das Abdeckteil 4 und das Funktionsteil 5 sind zu einem gebäudeseitig montierten Halteelement 6 der Ablaufvorrichtung 3 befestigbar. Das Funktionsteil 5 ist wahlweise ein Staufunktionsteil 7 oder ein Notüberlauffunktionsteil 8. Mit anderen Worten gesagt: Das Funktionsteil 5 kann aus der Gruppe von Staufunktionsteil 7 und Notüberlauffunktionsteil 8 ausgewählt werden.The inlet device 1 comprises a cover part 4 for covering the pipe inlet 2 and a functional part 5 . The functional part 5 is arranged below the cover part 4 . The cover part 4 is provided with a multiplicity of lateral passages 21 through which water can be supplied to the drainage device 3 . The cover part 4 and the functional part 5 can be fastened to a holding element 6 of the drain device 3 mounted on the building side. The functional part 5 is either a storage function part 7 or an emergency overflow function part 8. In other words, the functional part 5 can be selected from the group of storage function part 7 and emergency overflow function part 8.

Typischerweise werden auf einem zu entwässernden Gebäude mindestens eine bzw. eine Mehrzahl von Ablaufanordnung(en) 29 mit dem Staufunktionsteil 7 und mindestens eine bzw. eine Mehrzahl von Ablaufanordnung(en) 29 mit dem Notüberlauffunktionsteil 8 angeordnet.Typically, at least one or one on a building to be drained A plurality of drain arrangement(s) 29 with the accumulation function part 7 and at least one or a plurality of drain arrangement(s) 29 with the emergency overflow function part 8 are arranged.

In der Figur 2 wird das Funktionsteil 5 als Staufunktionsteil 7 gezeigt. Das Staufunktionsteil 7 liegt beabstandet zum Rohreintritt 2 der Ablaufvorrichtung 3, so dass ein freier Zwischenraum 35 zwischen Rohreintritt 2 und dem Staufunktionsteil 7 vorhanden ist. Durch diesen freien Zwischenraum 35 fliesst das abzuführende Wasser dem Rohreintritt 2 zu. Der Wasserfluss wird durch den Pfeil W dargestellt. Das Staufunktionsteil 7 dient zur Verhinderung eines Lufteintrittes in das Ablaufrohr 3, wenn der Wasserstand auf dem Gebäude eine Stauhöhe S erreicht bzw. überschritten hat. Die Stauhöhe S ist in der Figur 2 mit einer gestrichelten Linie eingezeichnet. Sobald das Wasser auf dem Gebäude G die Stauhöhe S erreicht hat, wird der Zufluss, hier der Zwischenraum 37, zum Rohreintritt 2 vollständig mit Wasser gefüllt und es kann ein Lufteintritt in den Rohreintritt 2 verhindert werden. Durch die dadurch entstehenden Strömungsverhältnisse kann die Abflussleistung gesteigert werden.In the figure 2 the functional part 5 is shown as a storage function part 7 . The accumulation function part 7 is at a distance from the pipe inlet 2 of the discharge device 3 so that there is a free space 35 between the pipe inlet 2 and the accumulation function part 7 . The water to be discharged flows to the pipe inlet 2 through this free intermediate space 35 . The water flow is represented by the arrow W. The storage function part 7 serves to prevent air from entering the drain pipe 3 when the water level on the building has reached or exceeded a storage height S. The water level S is in the figure 2 marked with a dashed line. As soon as the water on the building G has reached the storage level S, the inflow, here the intermediate space 37, to the pipe inlet 2 is completely filled with water and air can be prevented from entering the pipe inlet 2. Due to the resulting flow conditions, the discharge capacity can be increased.

In der Figur 3 wird das Funktionsteil als Notüberlauffunktionsteil 8 gezeigt. Das Notüberlauffunktionsteil 8 umfasst einen Einlauf 26, welcher eine Einlaufhöhe E definiert. Das Notüberlauffunktionsteil 8 stellt einen Notablauf bei Überschreiten der Einlaufhöhe E durch den Wasserstand auf dem Gebäude G bereit. In der Figur 3 ist die Einlaufhöhe E mit einer gestrichelten Linie dargestellt. Zwischen der Unterseite des Abdeckteils 4 und der Erhebung 13 ist ein freier Zwischenraum 37 vorhanden, durch welchen das abzuführende Wasser dem Einlauf 26 zuführbar ist.In the figure 3 the functional part is shown as emergency overflow functional part 8. The emergency overflow functional part 8 includes an inlet 26 which defines an inlet height E. The emergency overflow function part 8 provides an emergency drain when the water level on the building G exceeds the inlet height E. In the figure 3 the inlet height E is shown with a dashed line. Between the underside of the cover part 4 and the elevation 13 there is a free intermediate space 37 through which the water to be discharged can be fed to the inlet 26 .

Die Stauhöhe S des Staufunktionsteils 7 ist, wie in den Figuren 2 und 3 gezeigt, tiefer oder gleich als die Einlaufhöhe E des Notüberlauffunktionsteils 8. Das heisst, dass bis zum Erreichen der Einlaufhöhe E das Wasser über diejenigen Ablaufanordnungen abfliesst, welche mit dem Staufunktionsteil 7 ausgerüstet sind und bei Übersteigen der Einlaufhöhe E das Wasser über diejenigen Ablaufanordnungen abfliesst, welche mit dem Notüberlauffunktionsteil 8 ausgerüstet sind.The storage height S of the storage function part 7 is, as in the Figures 2 and 3 shown, lower than or equal to the inlet height E of the emergency overflow function part 8. This means that until the inlet height E is reached, the water flows out via those drainage arrangements which are equipped with the storage function part 7 and when the inlet height E is exceeded, the water flows out via those drainage arrangements which are equipped with the emergency overflow function part 8.

Das Abdeckteil 4 umfasst in der gezeigten Ausführung einen Deckelabschnitt 39, von welchem sich seitlich eine Vielzahl von Stegen 38 weg erstrecken. Die Stege 38 sind beabstandet zueinander angeordnet. Durch den Abstand werden die Durchgänge 21 geschaffen.In the embodiment shown, the cover part 4 comprises a cover section 39 of which a plurality of webs 38 extend laterally away. The webs 38 are arranged at a distance from one another. The passages 21 are created by the spacing.

Das Staufunktionsteil 7 und das Notüberlauffunktionsteil 8 verfügen über jeweils mindestens eine Befestigungsschnittstelle 15, über welche das jeweilige Funktionsteil 7, 8 zum Halteelement 6 der Ablaufvorrichtung 3 befestigbar ist. Die Befestigungsschnittstelle des Staufunktionsteils 7 ist dabei im Wesentlichen identisch zur Befestigungsschnittstelle des Notüberlauffunktionsteils 8 ausgebildet. Somit können beide Funktionsteile 7, 8 mit den gleichen Halteelementen 6 verbunden werden. Der Installateur kann vor Ort entscheiden, ob ein Staufunktionsteil 7 oder ein Notüberlauffunktionsteil 8 angeordnet werden soll, ohne dass an den Halteelementen 6 oder den Funktionsteilen 7, 8 Anpassungen vorgenommen werden müssen.The accumulation function part 7 and the emergency overflow function part 8 each have at least one attachment interface 15, via which the respective function part 7, 8 can be attached to the holding element 6 of the drain device 3. The attachment interface of the accumulation function part 7 is essentially identical in design to the attachment interface of the emergency overflow function part 8 . Thus, both functional parts 7, 8 can be connected to the same holding elements 6. The installer can decide on site whether a storage function part 7 or an emergency overflow function part 8 should be arranged without having to make any adjustments to the holding elements 6 or the function parts 7, 8.

Von den Figuren 2 und 3 kann weiter erkannt werden, dass sowohl das Staufunktionsteil 7 als auch das Notüberlauffunktionsteil 8 einen scheibenförmigen Basisabschnitt 9 aufweisen. Im montierten Zustand liegt der scheibenförmige Basisabschnitt 9 des Staufunktionsteils 7 und derjenige des Notüberlauffunktionsteils 8 vorzugsweise auf gleicher Höhe.Of the Figures 2 and 3 it can further be seen that both the accumulation function part 7 and the emergency overflow function part 8 have a disk-shaped base section 9 . In the assembled state, the disk-shaped base section 9 of the accumulation function part 7 and that of the emergency overflow function part 8 are preferably at the same height.

In der gezeigten Ausführungsform ist die besagte Befestigungsschnittstelle 15 Teil des Basisabschnittes 9. Die Befestigungsschnittstelle 15 wird hier als Öffnungen dargestellt, welches sich durch den Basisabschnitt 9 hindurch erstrecken. Über diese Öffnungen wird das Staufunktionsteil 7 bzw. das Notüberlauffunktionsteil 8 am Halteelement 6 gelagert. Das Halteelement 6 erstreckt sich dabei durch die Öffnung 15 hindurch.In the embodiment shown, said attachment interface 15 is part of the base portion 9. The attachment interface 15 is shown here as openings extending through the base portion 9. The accumulation function part 7 or the emergency overflow function part 8 is mounted on the holding element 6 via these openings. The holding element 6 extends through the opening 15 .

Die Stauhöhe S wird durch die Oberseite 11 des scheibenförmigen Basisabschnittes 9 definiert. Das Wasser kann also bis zum Oberseite 11 des scheibenförmigen Basisabschnittes 9 ansteigen und erst dann wird das Ansaugen von Luft verhindert.The accumulation height S is defined by the upper side 11 of the disc-shaped base section 9 . The water can therefore rise to the top 11 of the disc-shaped base section 9 and only then is the suction of air prevented.

Beim Notüberlauffunktionsteil 8 weist der Basisabschnitt 9 eine den Einlauf 26 bereitstellende Durchlassöffnung 10 auf. Die Durchlassöffnung 10 wird hier durch eine Erhebung 12, die sich vom scheibenförmigen Basisabschnitt 9, erstreckt vollständig umgeben. Die Erhebung 12 umgibt die Durchlassöffnung 10 im Wesentlichen vollständig. Die Oberkante 13 der Erhebung 12 definiert dabei die Einlaufhöhe E. Die Erhebung 12 ist hier Teil eines Rohrabschnittes 14, welcher sich von der Oberkante 13 der Erhebung durch den scheibenförmigen Basisabschnitt 9 hindurch erstreckt und in Einbaulage, so wie in der Figur 3 gezeigt, in den Rohreintritt 2 der Ablaufvorrichtung 3 einragt. Vorzugsweise ist die Verbindung zwischen Rohrabschnitt 14 und Roheintritt 2 bezüglich Wasser dicht ausgebildet. Das Wasser fliesst entlang des Pfeils W durch die Durchgänge 21 des Abdeckteils 4 hindurch und fliesst dann über die Erhebung 12 in den Rohrabschnitt 14 und somit in die Ablaufvorrichtung 3 ein.In the case of the emergency overflow functional part 8 , the base section 9 has a passage opening 10 providing the inlet 26 . The through-opening 10 is completed here by an elevation 12 which extends from the disc-shaped base section 9 surround. The elevation 12 essentially completely surrounds the passage opening 10 . The top edge 13 of the survey 12 defines the inlet height E. The survey 12 is part of a pipe section 14 here, which extends from the top edge 13 of the survey through the disc-shaped base section 9 and in the installed position, as in FIG figure 3 shown, in the pipe inlet 2 of the drain device 3 protrudes. The connection between pipe section 14 and raw inlet 2 is preferably designed to be watertight. The water flows along the arrow W through the passages 21 of the cover part 4 and then flows via the elevation 12 into the pipe section 14 and thus into the drain device 3 .

In den Explosionsansichten der Figuren 4 bis 9 werden verschiedene Anordnungen der Öffnung 15, welche in den gezeigten Ausführungsformen die besagte Befestigungsschnittstelle bereitstellt, gezeigt.In the exploded views of the Figures 4 to 9 Different arrangements of the opening 15, which in the shown embodiments provide said attachment interface, are shown.

In den Figuren 4 bis 5 ist die Öffnung 15 im Basisabschnitt 9 angeordnet. Der scheibenförmige Basisabschnitt 9 ist dabei im Bereich der Öffnung 15 eben, also flach, ausgebildet.In the Figures 4 to 5 the opening 15 is arranged in the base section 9 . The disk-shaped base section 9 is planar, ie flat, in the area of the opening 15 .

In den Figuren 6 bis 9 werden zwei weitere Varianten gezeigt. Hier ist der scheibenförmige Basisabschnitt 9 im Bereich der Öffnung 15 mit einer Ausbuchtung 16 ausgebildet. Die Ausbuchtung 16 erstreckt sich dabei vom Abdeckteil 4 weg, also in Richtung Ablaufvorrichtung 3. Die Öffnung 15 liegt am Grund der Ausbuchtung 16 und ist demnach in der Ausbuchtung 16 angeordnet. Die Ausbuchtung 16 hat den Vorteil, dass die Unterseite des scheibenförmigen Basisabschnittes 9, welche der Ablaufvorrichtung 3 zugewandt ist, näher bei der Ablaufvorrichtung 3 liegt. Hierdurch können die Halteelemente 6 entsprechen kürzer ausgebildet werden, was bei der Montage den Vorteil hat, dass diese weniger durch Werkzeuge oder Installateure abgedrückt werden können. Diese Funktion wird beim Vergleich der Länge der Halteelemente 6 zwischen den Figuren 4 und 5 und den Figuren 6 bis 9 augenscheinlich.In the Figures 6 to 9 two more variants are shown. Here the disc-shaped base section 9 is formed with a bulge 16 in the area of the opening 15 . The bulge 16 extends away from the cover part 4, ie in the direction of the drain device 3. The opening 15 is located at the base of the bulge 16 and is therefore arranged in the bulge 16. The bulge 16 has the advantage that the underside of the disc-shaped base section 9, which faces the drain device 3, is closer to the drain device 3. As a result, the holding elements 6 can be designed to be correspondingly shorter, which has the advantage during assembly that they can be pushed off less by tools or installers. This function is when comparing the length of the support members 6 between the Figures 4 and 5 and the Figures 6 to 9 apparently.

In den Figuren 6 bis 7 ist die Ausbuchtung 9 derart angeordnet, dass diese durch den Basisabschnitt 9 umgeben wird. In den Figuren 8 bis 9 ist die Ausbuchtung 9 derart angeordnet, dass diese bezüglich des Randes des Basisabschnittes 9 offen ausgebildet ist. Weiter ist in den gezeigten Ausführungsformen nach den Figuren 1 bis 9 ein Befestigungselement 17 am Abdeckteil 4 verschiebbar gelagert. Das Befestigungselement 17 ist hier am Abdeckteil 4 drehbar gelagert und kann von einer Entriegelungslage in eine Verriegelungslage gebracht werden. Das Befestigungselement 17 arbeitet mit dem Halteelement 6 zusammen und sichert das Abdeckteil 4 sowie das Funktionsteil 7, 8 zum Halteelement 6. In der Verriegelungslage kann also das Abdeckteil 4 und die Funktionsteile 7, 8 nicht vom Halteelement 6 getrennt werden. In der Entriegelungslage können die beiden Teile vom Halteelement 6 entfernt werden. Das Befestigungselement 17 greift mit einer Rastausnehmung 36 in eine Rille 20 am Halteelement 6, welches hier die Gestalt eines Zapfens 19. Die Rille 20 kann auch eine nicht vollständig umlaufende Kerbe sein. Hierdurch wird das Abdeckteil 4 zum Halteelement 6 gesichert. Das Halteelement 6 umfasst weiter eine Lagerfläche 24. Weiter ragt das Halteelement 6 durch die Öffnung 15 am Funktionselement 7, 8 hindurch und letzteres liegt mit seiner Unterseite 25 auf der Lagerfläche 24 auf. Durch den Kontakt mit dem Befestigungselement 17 wird das Funktionselement 7, 8 zwischen Lagerfläche 24 und Befestigungselement 17 geklemmt und so zum Halteelement 6 gesichert.In the Figures 6 to 7 the bulge 9 is arranged in such a way that it is surrounded by the base portion 9 . In the Figures 8 to 9 the bulge 9 is arranged in such a way that it is open with respect to the edge of the base section 9 . Next is in the embodiments shown according to Figures 1 to 9 a fastener 17 mounted on the cover 4 slidably. The fastening element 17 is rotatably mounted here on the cover part 4 and can be brought from an unlocked position into a locked position. The fastening element 17 works together with the holding element 6 and secures the cover part 4 and the functional part 7, 8 to the holding element 6. In the locked position, the cover part 4 and the functional parts 7, 8 cannot be separated from the holding element 6. The two parts can be removed from the holding element 6 in the unlocked position. The fastening element 17 engages with a locking recess 36 in a groove 20 on the holding element 6, which here is in the form of a pin 19. The groove 20 can also be a notch that does not run all the way round. As a result, the cover part 4 is secured to the holding element 6 . The holding element 6 also includes a bearing surface 24 . The holding element 6 also protrudes through the opening 15 on the functional element 7 , 8 and the latter rests with its underside 25 on the bearing surface 24 . Due to the contact with the fastening element 17, the functional element 7, 8 is clamped between the bearing surface 24 and the fastening element 17 and is thus secured to the holding element 6.

Im vorliegenden Fall sind zwei Befestigungselemente 17 angeordnet. Es wäre auch denkbar nur ein oder mehr als zwei Befestigungselemente 17 vorzusehen. Die Zahl der Halteelement 9 entspricht vorzugsweise der Zahl der Befestigungselemente.In the present case, two fastening elements 17 are arranged. It would also be conceivable to provide only one or more than two fastening elements 17 . The number of holding elements 9 preferably corresponds to the number of fastening elements.

In der gezeigten Ausführungsform sind die Befestigungselemente 17 zweiteilig ausgebildet. Die Befestigungselement 17 umfassen dabei einen Aktuatorteil 22 und einen Verriegelungsteil 23. Das Aktuatorteil 22 steht dabei mit dem Verriegelungsteil 23 in Verbindung.
