The latch bolt 60 'for lifting the unit 11, on the other hand, is flap-like, i.e. trained with one arm, so that he always strives to occupy his closed position.

Die Funktion der Handhabungsvorrichtung 10 zum einfachen Verriegeln und Entriegeln der Kupplungseinheit 25 und 60 bzw. 25 und 60' ist folgende: zum Absenken des Aggregates 11 wird außerhalb des betreffenden Behälters, Beckens oder dergleichen das Hubgestell 35 über das Aggregat 11 derart gebracht, daß der Hubbügel 25 den Aufnahmeschlitz 51 soweit durchdringt, daß der Fallriegel 60 von Hand geschlossen und solange geschlossen gehalten werden kann, bis nach Anheben des Hubgestells 35 das obere Ende des Hubbügels 25 auf dem den Aufnahmeschlitz 51 überbrückenden Riegelteil des geschlossenen Fallriegels 60 aufliegt. In diesem Zustand, in welchem das Aggregat 11 mit seinem Bügel 25 am Fallriegel 60 hängt, wird das Aggregat 11 mit Hilfe der Handhabungsvorrichtung 10 und des Hebezeugs beim dargestellten Ausführungsbeispiel an der Führungseinrichtung 12 abgelassen. Sobald das Aggregat 11 sich in seiner Arbeitsposition befindet, d.h. am Anschlag 26 aufliegt und die Anschlagvorrichtung 15 weiter abgelassen wird, kommt das freie Ende 59 des Fallriegels 60 vom Hubbügel 25 frei, so daß sich der Fallriegel 60 automatisch öffnen kann. Wird nun die Anschlagvorrichtung 15 wieder angehoben, kann der Hubbügel 25 ungehindert aus dem Aufnahmeschlitz 51 am Hubgestell 35 freikommen. Das Aggregat 11 bleibt in seiner Arbeitsposition, während die Anschlagvorrichtung 15 entfernt werden kann.The function of the handling device 10 for simply locking and unlocking the coupling unit 25 and 60 or 25 and 60 'is as follows: for lowering the unit 11, the lifting frame 35 is brought over the unit 11 in such a way that the unit outside the container, basin or the like in question Lifting bracket 25 penetrates the receiving slot 51 so far that the latch bolt 60 can be closed by hand and kept closed until after lifting the lifting frame 35 the upper end of the lifting bracket 25 rests on the latch part of the closed latch bolt 60 bridging the receiving slot 51. In this state, in which the unit 11 hangs on the latch 60 with its bracket 25, the unit 11 is lowered on the guide device 12 with the aid of the handling device 10 and the lifting device in the exemplary embodiment shown. As soon as the unit 11 is in its working position, ie rests on the stop 26 and the stop device 15 is lowered further, the free end 59 of the latch bolt 60 is released from the lifting bracket 25, so that the latch bolt 60 can open automatically. If the stop device 15 is now raised again, the lifting bracket 25 can freely come out of the receiving slot 51 on the lifting frame 35. The unit 11 remains in its working position while the stop device 15 can be removed.

Zum Anheben bzw. Herausholen eines Aggregats 11 aus dem Behälter bzw. Becken oder dergleichen wird das nicht im einzelnen dargestellte Hebezeug statt mit der Anschlagvorrichtung 15 mit der Anschlagvorrichtung 15', die den Fallriegel 60' beinhaltet, verbunden und abgesenkt. Im Bereich der Arbeitsposition des anzuhebenden Aggregats 11 gelangt beim Absenken der Anschlagvorrichtung 15' der Hubbügel 25 zwischen den Abweisblechen 52, 53 hindurch in den Aufnahmeschlitz 51, wobei das obere Ende des Hubbügels 25 den geschlossenen Fallriegel 60' öffnet. Sobald das obere Ende des Hubbügels 25 ausreichend weit durch den Aufnahmeschlitz 51 gelangt ist, kann der Fallriegel 60' sich aufgrund des Eigengewichts des freien Endes 59' wieder schließen. Danach wird die Anschlagvorrichtung 15' wieder nach oben gezogen bzw. angehoben, so daß das obere Ende des Hubbügels 25 auf dem Riegelteil des geschlossenen Fallriegels 60' zu liegen kommt und mit der Anschlagvorrichtung 15' angehoben werden kann.In order to lift or remove an assembly 11 from the container or basin or the like, the lifting device, which is not shown in detail, is connected and lowered with the stop device 15 ', which includes the latch bolt 60', instead of with the stop device 15. In the area of the working position of the unit 11 to be lifted, when the stop device 15 ′ is lowered, the lifting bracket 25 passes between the deflection plates 52, 53 into the receiving slot 51, the upper end of the lifting bracket 25 being the closed latchbolt 60 'opens. As soon as the upper end of the lifting bracket 25 has passed sufficiently far through the receiving slot 51, the latch bolt 60 'can close again due to the weight of the free end 59'. Then the stop device 15 'is pulled up or raised again, so that the upper end of the lifting bracket 25 comes to rest on the latch part of the closed latch bolt 60' and can be raised with the stop device 15 '.

Mit Hilfe der Handhabungsvorrichtung 10 können verschiedene Aggregate 11, die in einem Becken oder dergleichen arbeiten, angehoben bzw. abgesenkt werden. Hierzu ist der Abstand D zwischen dem Fallriegel 60 bzw. 60' der Anschlagvorrichtung 15 bzw. 15' und dem Rohr 16 der Führungseinrichtung 12 in beschriebener Weise über die teleskopartige Verbindung der Stangen 33, 34 mit den Aufnahmen 36, 37 einstellbar.With the help of the handling device 10, various units 11 which work in a basin or the like can be raised or lowered. For this purpose, the distance D between the latch bolt 60 or 60 'of the stop device 15 or 15' and the tube 16 of the guide device 12 can be adjusted in the manner described via the telescopic connection of the rods 33, 34 to the receptacles 36, 37.

Insbesondere durch die Anordnung der Abweisbleche 52, 53 an der dem Hubbügel 25 des Aggregats 11 zugewandten Seite des Aufnahmeschlitz 51 ist es auch möglich, die Anschlagvorrichtung 15 bzw. 15' frei beweglich ohne Zuhilfenahme der Führungseinrichtung 12 zu verwenden. Entsprechendes gilt für das Aggregat 11, das dann, wenn es eine geeignete Form und Aufsetzfläche aufweist, mit Hilfe einer derartigen Handhabungsvorrichtung frei beweglich ohne Führungseinrichtung 12 abgesenkt und angehoben werden kann.In particular, by arranging the deflector plates 52, 53 on the side of the receiving slot 51 facing the lifting bracket 25 of the assembly 11, it is also possible to use the stop device 15 or 15 ′ in a freely movable manner without the aid of the guide device 12. The same applies to the unit 11, which, if it has a suitable shape and contact surface, can be lowered and raised freely with the aid of such a handling device without a guide device 12.
