Bei dem neuen Verschluß wird die Sper-, rung und Sicherung durch schraubengangartige Gebilde bewirkt, welche im Sinne einer zwei- oder mehrgängigen Schraube ineinandergreifen, wobei der eine Teil unter Wirkung einer Feder steht und mittels Schlüssels durch eine Schließplatte bewegt wird. Der Verschlußbolzen α besitzt an einem Ende den festen Bolzenkopf b. Sein anderes Ende ist in der Weise in Form einer doppelgängigen Schraube derart gefräst, daß ein glatter, runder Kern c gebildet wird, auf welchem die schräg stehenden Nasen d stehenbleiben, während in der diesen entgegengesetzten Richtung. schräg die Schraubennuten η verlaufen (Abb. 4 und 7).In the new lock, the locking, locking and securing is effected by screw-thread-like structures, which interlock in the sense of a two-thread or multiple-thread screw, one part being under the action of a spring and being moved through a locking plate by means of a key. The locking bolt α has the fixed bolt head b at one end. Its other end is milled in such a way in the form of a double screw that a smooth, round core c is formed, on which the inclined lugs d stop while in the opposite direction. the screw grooves η run obliquely (Fig. 4 and 7).

Das Verschlußgehäuse zu diesem Bolzen besteht aus einer innen genügend Raum lassenden zylindrischen Hülse g, in deren unteren Rand ein Ringstück / fest eingesetzt ist. Auf diesem Ringstück / sitzen kurze Führungsstücke m eines doppelgängigen Gewindes, welche in die Schraubennuten η passen und bei entsprechender kurzer Drehung des Ringes I darin laufen, wobei der Ring / gleichzeitig seine Führung auf dem stärkereu Schaftteil des Bolzens α findet. In dem oberen Raum der Hülse g ist die eigentliche Schließvorrichtung untergebracht. Diese besteht aus einem flachen Ring e, an welchem ein zylindrischer Teil f befestigt ist, der nach unten derart ausgefräst ist, daß er auf beiden Seiten die schrägen Nasen q bildet, die unter die schrägen Nasen d greifen (Abb. 1), wobei dann diese Teile mit dem oberen Schaftteil des Bolzens α ineinandergreifen und zusammenpassen. Auf dem oberen Teil der Hülse /bewegt sich in passenden Führungen der Hülse g eine runde Scheibe h, welche die Hülse f durch Mitnehmer i mitbewegt, was aber in einer solchen Weise geschieht, daß bei dieser Drehung durch die Scheibe h der flache Ring e mit der Hülse f in bestimmten Grenzen eine achsiale Bewegung durchmachen kann. Um den oberen Teil der Hülse / ist eine Feder k gelegt, welche mit einem Ende an der äußeren Hülse g, mit dem anderen Ende an dem flachen Ring e befestigt und derart gespannt ist, daß sie bestrebt ist, diesen Ring e und damit die Hülse / so zu drehen, daß die Nasen q unter die Nasen d greifen. Bei der geöffneten Stellung des Verschlusses wird dieser Eingriff aber zunächst dadurch gehindert, daß, wie Abb. 2 zeigt, die Nasen q gegen einen Vorsprung w anliegen, der somit die ganze federnde Verriegelungsvorrichtung in der geöffneten Stellung vorerst festhält.The lock housing for this bolt consists of a cylindrical sleeve g which leaves enough space inside and in the lower edge of which a ring piece / is firmly inserted. On this ring piece / sit short guide pieces m of a double thread, which fit into the screw grooves η and run in it with a corresponding short rotation of the ring I , the ring / at the same time finding its guide on the strongeru shaft part of the bolt α . The actual locking device is housed in the upper space of the sleeve g. This consists of a flat ring e, to which a cylindrical part f is attached, which is milled downwards in such a way that it forms the inclined lugs q on both sides, which engage under the inclined lugs d (Fig. 1), in which case these parts mesh with the upper shank part of the bolt α and fit together. On the upper part of the sleeve / a round disk h moves in suitable guides of the sleeve g , which moves the sleeve f with the driver i , but this happens in such a way that the flat ring e with this rotation through the disk h the sleeve f can undergo an axial movement within certain limits. Around the upper part of the sleeve / a spring k is placed, which is attached with one end to the outer sleeve g, with the other end to the flat ring e and is so tensioned that it tends to this ring e and thus the sleeve / to turn so that the lugs q engage under the lugs d. In the open position of the lock, this engagement is initially prevented by the fact that, as shown in Fig. 2, the lugs q rest against a projection w which thus initially holds the entire resilient locking device in the open position.

In der runden Scheibe //, die somit die unter inr liegende ganze Verriegelungsvorrichtung abdeckt, befinden sich die Angriffe für den Schlüssel. Diese bestehen im vorliegenden Beispiel aus zwei kantigen Löchern s_} in welche die entsprechenden Nasen s¹ des Schlüsselbartcs r hineinpassen. Man kann somit mittels dieses Schlüssels die runde Scheibe h entsprechend drehen, und bewegt damit durch die Mitnehmer i gleichzeitig auch den Ring e mit der Hülse /, wodurch die schrägen Nasen q aus der Schlußstellung der Abb. 1 in die Offenstellung der Abb. 2 gedreht werden und sich hier hinter den Vorsprängen w festsetzen.The handles for the key are located in the round disc //, which thus covers the entire locking device underneath. In the present example, these consist of two angular holes s _} into which the corresponding lugs s ^{1 of} the key bit r fit. With this key you can turn the round disk h accordingly, and thus move the ring e with the sleeve / at the same time through the driver i , whereby the inclined lugs q are rotated from the closed position of Fig. 1 to the open position of Fig. 2 and fix themselves here behind the projections w.

In dieser Stellung kann man nun die äußere Hülse g und damit den ganzen Verschluß in einer leichten Linksdrehung von dem Verschlußbolzen a, b abziehen, wobei die Füh-In this position you can pull the outer sleeve g and thus the entire lock with a slight left turn from the lock bolt a, b , with the guide

Claims

rungs pieces in in the screw grooves η themselves | unscrew. The lock is thus released. - S To close, the locking bolt j is pushed back onto the bolt shank α, taking care that the short j guide pieces m engage in the grooves η. : When the bolt a \ was pulled out of the bolt head, the j ίο projection w had also pulled out, which freed the lugs q and therefore rotated and advanced under the simultaneous axial and radial pressure j of the spring k so far that they now rest against the upper edge of the guide pieces m and block the latter at the top when the bolt head is removed. But as soon as these guide pieces m engage in the grooves η, the projections w also move forward in the same way and, as can be seen in Fig Thread pieces 111 are stripped off and now at the last moment, as soon as the bolt head is pressed very firmly, are so free that they jump under the action of the spring k completely in the final position according to Fig. Ι, with which the conclusion is made. The outer sleeve g, which forms the lock housing, is closed by a cover 0 which only leaves the keyhole p matching the key r open. If at the same time a further, easily recognizable to the outside protection against unauthorized opening is to be connected to this connection device in the manner of the previous sealing, for example in rail freight cars, then it is necessary that it is provided with a device through which every attempt to open the lock without authorization is immediately recognizable. For this purpose, as can be seen from Fig. 5 and 6, a second sleeve t is placed over the sleeve g, which is held in place at the bottom by two inwardly projecting lugs u in such a way that it can be turned freely when the lock is removed and also as soon as the lugs u are positioned so that they coincide with the recesses ν and can be moved axially so far that the cover 0 of the sleeve g is free (Fig. 5). If you insert a paper disc with the required markings in this position, then press the sleeve t down and turn it into the position shown in Fig. 6, so that the lugs u come to lie exactly in the thread of the guide piece m, then in this position the bolt head can be pushed onto the bolt α in exactly the same way as described earlier, the lugs u then also entering the threaded grooves η until the final position is reached. In this position, the outermost sleeve t is therefore also secured, and the inserted paper disc is held and enclosed in such a way that it covers the keyhole p on the inside. If you want to open the lock now, this can only be done by means of the associated key by pushing the key through this inserted paper disk. Since it is not possible to loosen the lock without damaging this paper disk, it offers the most reliable guarantee that the contents of the car have remained intact as long as it is not damaged.
