Description

Lukendeckelverschlußvorrichtung Zweck der Erfindung ist es, einen bekannten Lukendeckelverschluß, dessen federbelasteter Keil beim Schließen der Luke selbsttätig über einer Nase einrastet, so zu gestalten, daß diese Verkeilung den Deckel auch bei schwerem Seegang gegen den Seeschlag und starke Beschleunigungskräfte sicher gegen die Dichtung preßt. Diese Aufgabe wird dadurch gelöst, daß erfindungsgemäß die Schließfläche des Keiles und der Nase die Form ein und desselben Kreisbogens haben und daß der Keil in einem Punkt drehbar gelagert ist, der oberhalb und/oder seitlich von dem 1 ittelpunkt des Kreisbogens liegt.Hatch cover locking device The purpose of the invention is to design a known hatch cover lock, the spring-loaded wedge of which automatically engages over a nose when the hatch is closed, so that this wedging presses the lid securely against the seal even in rough seas against the impact of the sea and strong acceleration forces. This object is achieved in that, according to the invention, the closing surface of the wedge and the nose have the shape of one and the same circular arc and that the wedge is rotatably mounted at a point which is above and / or to the side of the 1 central point of the circular arc.

Die Figur zeigt einen Deckelabschnitt 1 mit einem Dichtungsgummi 2, das gegen einen Süllwinkel am Lukensüll4 gepreßt wird. Am Deckel ist ein Nasenblech 5 mit einer Nase 6 angebracht.The figure shows a cover section 1 with a rubber seal 2, which is pressed against a coaming on the hatch coaming4. There is a nose plate on the lid 5 attached with a nose 6.

Beim Schließen des Deckels tritt die Nase durch eine Öffnung 7 im Süllwinkel und drückt dabei einen federbelasteten Schließkeil 8 beseite. Bei geschlossenem Deckel rastet dieser federbelastete Schließkeil selbstt iitig über der Nase ein. Die Schließfläche dieses Keiles ist ein Kreisbogen. Der Schließkeil ist in einem Punkt derart drehbar gelagert, daß der Drehpunkt nicht im Mittelpunkt des Kreisbogens der Schließfläche liegt. Dadurch zieht sich der Keilverschluß bei geringen Bewegungen des Deckels gegenüber dem Süll stets fester an. Der erforderliche Federdruck wird von einer Feder 9 erzeugt. Zum Öffnen des Verschlusses dient ein Hebel, der von Hand bedient werden kann, oder ein gegenüber der Feder liegender hydraulischer Druckkolben 10, der durch einen Gegendruck den Schließkeil von der Nase löst. Dieser hydraulische Druckkolben wird dann verwendet, wenn die Lukendeckel mit einer hydraulischen Vorrichtung bewegt werden und ist mit dieser derart verbunden, daß der hvdraulischeDruckkolben denKeilverschluß bei einem geringeren als zum Bewegen des Deckels erforderlichen Druck öffnet.When the lid is closed, the nose enters through an opening 7 in the Coaming angle and pushes a spring-loaded striker 8 aside. When closed This spring-loaded locking wedge automatically locks into place over the nose. The closing surface of this wedge is an arc of a circle. The striker is in one Point rotatably mounted in such a way that the pivot point is not in the center of the circular arc the closing surface. As a result, the wedge lock pulls with small movements the lid is always tighter than the coaming. The required spring pressure is generated by a spring 9. A lever is used to open the lock Can be operated manually, or a hydraulic pressure piston located opposite the spring 10, which releases the striker from the nose with counter pressure. This hydraulic one Pressure piston is used when the hatch cover with a hydraulic device are moved and is connected to this in such a way that the hydraulic pressure piston the wedge lock at less than that required to move the lid Pressure opens.
