Description

Schraubengetriebe für Klappdavits. Schraubengetriebe für Klappdavits sind bekannt, bei denen das Schraubengetriebe aus einer Schraubenspindel besteht, die von einer Schraubenhülse umgeben wird, um gegen äußere Witterungseinflüsse geschützt zu sein. Diese Klappdavits sowie auch alle anderen bdeher bekannten D;avits haben den Nachteil, daß sie einen verhältnismäßig großen, Schiffsraum in Anspruch nehmen. Bei dem besprochenen Schraubengetriebe findet die Befestigung mit dem Davitarm am Ende der Spindel oder der Schraubenhülse statt,, so daß das Schraubengetriebe weit in den Schiffsraum hineinreichen muß.Screw gear for folding davits. Screw gear for folding davits are known in which the screw gear consists of a screw spindle, which is surrounded by a screw sleeve to protect against external weather conditions to be. These folding davits as well as all other known D; avits have the disadvantage that they take up a relatively large ship space. The screw gear discussed above is attached to the davit arm on the End of the spindle or the screw sleeve instead, so that the screw gear wide must reach into the hold.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, den Raum zur Aufnahme der Antriebsvorrichtung für Klappdavits zu verringern. Zu diesem Zweck, wird die -die Schraubenspindel umgebende Hülse nicht mit ihrem Ende mit dem Davit verbunden, sondenn seitlich durch einen Zapfen, der zwischen ,ihnen Enden angebracht ist. Die Schraubenspindel ist in einem Bock drehbar gelagert und schwingt beim Vortreiben oder Zurückziehen des Davitarms entsprechend aus. Durch diese Anordnung wird ein kürzerer Abstand zwischen Spindellagerung und Davitarm erreicht als die Spindellänge beträgty wodurch eine Ersparnis des Decksraumes erzielt wird.The present invention is based on the object of the space to To reduce the inclusion of the drive device for folding davits. To this end, the sleeve surrounding the screw spindle does not end with the davit connected, probes laterally by a peg that between, them Ends is attached. The screw spindle is rotatably mounted in a bracket and swings out accordingly when advancing or withdrawing the davit arm. By this arrangement results in a shorter distance between the spindle bearing and the davit arm reached than the spindle length is y, thereby saving the deck space will.

Abb. i der Zeichnung zeigt die Einrichtung in Seitenansicht und Abb.2 in Endansicht. Abb. 3 zeigt das Schraubengetriebe im Längsschnitt.Fig. I of the drawing shows the device in side view and Fig.2 in end view. Fig. 3 shows the screw gear in longitudinal section.

Bei der dargestellten Ausführungsform ist der Davitarm a am Fuße des Bockes b drehbar gelagert, an dem oben die Schraubenspindel d mit ihrem äußersten Ende ihre drehbare Lagerung findet. Diese Spindel besitzt, wie an sich bekannt, an ihrem freien Ende d einen Vierkant zum Ansetzen der. Kurbel.. Die Umschließungshülse e, in die die Spindel e eingeschraubt ist, besitzt in einem gewissen Abstande von ihrem freien Ende einen seitlichen Zapfen f, der drehbar in den Arm a eingreift, so daß an einer- Stelle zwischen den Enden der Hülse e diese gelenkig mit dem Dmhtarm verbunden ist. Es leuchtet ein, daß die Hülse eine erheblich größere Länge erhalten kann, als dem Abstand zwpschen der Anschlußstelle an den Davitaxm und der Lagerstelle für die Spindelt -entspricht, so daß der Ausschlag, wie aus Uer punktierten Stellung in Abb. i hervorgeht, ein. verhältnismäßig großer sein kann, und mithin, ohne dem Davitarm eine beträchtliche Länge zu geben, das an ihm hängende Rettungsboot in genügender Entfernung über den .Schiffsrand heraus ausgesetzt werden kann und weder der Tragbock b noch die auf den Vierkant aufgesetzte Kurbel weit in den Schiffsraum hineinzureichen brauchen.In the illustrated embodiment, the davit arm a is at the foot of the Bockes b rotatably mounted on the top of the screw spindle d with its outermost Finds its rotatable bearing at the end. As is known per se, this spindle has at its free end d a square for attaching the. Crank .. The containment sleeve e, into which the spindle e is screwed, is at a certain distance from its free end has a lateral pin f, which engages rotatably in the arm a, so that at one point between the ends of the sleeve e this articulated with the Dmhtarm connected is. It is clear that the sleeve should be given a considerably greater length can, as the distance between the connection point on the davitaxm and the storage point for the spindle-corresponds, so that the deflection, as from Uer dotted position shown in Fig. i, a. can be relatively larger, and therefore without that To give the davit arm a considerable length, the lifeboat hanging on it in sufficient distance beyond the edge of the ship can be exposed and neither the trestle b and the crank placed on the square drive far into the hold need to reach in.

Claims (1)

PATENT-ANSpRUcH: Schraubengetriebe für Klappdavits, bestehend aus einer mit einem Ende in einem Bock drehbar und schwingbar gelagerten Schrauhemspindel und einer die Spindel auf ihrer ganzen Länge umschließenden Schraubhülse, dadurch gekennzeichnet, daß die Hülse (e) mittels eines seitlich an ihr zwischen ihren Enden angebrachten Zapfens schwenkbar am Davitarm angreift. PATENT CLAIM: Screw gear for folding davits, consisting of a screw spindle rotatably and swingably mounted with one end in a bracket and a screw sleeve enclosing the spindle over its entire length, characterized in that the sleeve (s) by means of a laterally on her between its ends attached pin pivotally engages the davit arm.
