Die Erfindung bezieht sich auf solche Schlösser mit einer vom Schlüssel gedrehten, in einem festen Zylinder gelagerten Trommel, bei denen die Trommel durch in den äußeren Zylinder eingreifende Sperrkörper am Drehen verhindert wird und erst gedreht werden kann, wenn in der Trommel gelagerte Zuhaltungsscheiben derartig eingestellt werden, daß in deren Nuten eine Sperrleiste eintreten kann.The invention relates to such locks with a turned by the key, The drum is stored in a fixed cylinder and the drum passes through the outer one Cylinder engaging locking body is prevented from rotating and can only be rotated, if tumbler disks stored in the drum are set in such a way that in the grooves of which a locking strip can enter.

ίο Von bekannten Schlössern dieser Art unterscheidet sich das Schloß nach dieser Erfindung dadurch, daß die durch die Sperrscheiben (Zuhaltungen) in der Sperrlage des Schlosses festgehaltenen Leisten nicht unmittelbar diejenigen Körper bilden, welche die Trommel am Außenzylinder festhalten, sondern durch Vermittlung von Kolben auf Stahlkugeln einwirken, Welche die eigentlichen Sperrkörper bilden, so daß das Schloß durch Anbohren von außen und Aufbrechen nicht geöffnet werden kann. Dabei können die Sperrscheiben so gelagert sein, daß sie in verschiedenen Richtungen oder in verschiedenem Sinne verschoben werden müssen, wenn das Schloß geöffnet werden soll.ίο Differs from known locks of this type The lock according to this invention is characterized in that the locking discs (tumblers) are in the locked position of the lock The bars held in place do not directly form those bodies that make up the drum hold on to the outer cylinder, but act on steel balls by means of pistons, Which form the actual locking body, so that the lock can be drilled cannot be opened from the outside and prying open. The locking washers be positioned so that they are shifted in different directions or in different senses must be when the lock is to be opened.

Auf der Zeichnung ist eine Ausführungsform des Schlosses dargestellt, und zwar inIn the drawing, an embodiment of the lock is shown, namely in

Das Schloß besteht in der Hauptsache aus der feststehenden Trommel oder dem zylindrischen Gehäuse α und der im Innern derselben drehbaren konzentrischen Trommel c. Die Trommel c trägt in bekannter Weise die 40 The lock consists mainly of the fixed drum or the cylindrical housing α and the concentric drum c rotatable inside the same. The drum c carries the 40 in a known manner

beiden Stifte e, die auf den Riegel des Schlosses wirken und ihn vor- und zurückschieben, je nachdem die Trommel c im einen oder im anderen Sinne gedreht wird.two pins e, which act on the bolt of the lock and push it back and forth, depending on whether the drum c is rotated in one sense or the other.

Die beiden Trommeln α und c sind in der normalen Schlußstellung gegeneinander gesperrt durch eine gewisse Anzahl von Kugeln b aus gehärtetem Stahl, deren in dem dargestellten Ausführungsbeispiel vier vorhanden sind, die in der beweglichen Trommel c untergebracht sind und in kugelige Ausnehmungen d der festen Trommel α eingreifen und in dieser Lage durch Kolben r abgestützt werden, die mittels Stangen mit einer Leiste f fest verbunden sind, welche durch kleine Hilfskolben i in der beweglichen Trommel c geführt ist.The two drums α and c are locked against each other in the normal final position by a certain number of balls b made of hardened steel, four of which are present in the illustrated embodiment, which are housed in the movable drum c and in spherical recesses d of the fixed drum α engage and are supported in this position by pistons r , which are firmly connected by means of rods to a bar f , which is guided by small auxiliary pistons i in the movable drum c.

Federn s, die auf die Kolben r wirken und die sich gegen den Boden der Höhlungen in der Trommel c abstützen, drängen stets die Kugeln b in die Ausnehmungen d der äußeren Trommel a. Um die innere Trommel c drehen zu können, müssen die Kugeln b in die dazu vorgesehenen Höhlungen unter Zusammendrückung der Federn s zurückgedrängt werden. Hierzu ist aber erforderlich, daß die Leisten f sich der Trommelachse nähern können.Springs s, which act on the pistons r and which are supported against the bottom of the cavities in the drum c, always urge the balls b into the recesses d of the outer drum a. In order to be able to rotate the inner drum c, the balls b must be pushed back into the cavities provided for this purpose while the springs s are compressed. For this, however, it is necessary that the strips f can approach the drum axis.

In der Schließstellung bilden sämtliche Scheiben g des Schlosses Anschläge für die Leisten f, welche dadurch die Kolben in den Ausnehmungen der äußeren Trommel festhalten. ■ Wenn aber mit dem Schlüssel die verschiedenen Scheiben bestimmte Strecken verschoben worden sind, werden die Leisten f frei, so daß sie sich nach der Trommelachse hin bewegen können.In the closed position, all the disks g of the lock form stops for the strips f, which thereby hold the pistons in the recesses of the outer drum. If, however, the various disks have been moved certain distances with the key, the strips f become free so that they can move towards the drum axis.

Claims

angular shape that lie between straight guides. Springs h constantly strive to return these disks to the position corresponding to the locking position, ie the position in which these disks act as a support or abutment for the strips f .

Each of the disks g has an incision m on the edge, into which the corresponding strip f can insert itself when the disk through

ίο the special key introduced at k has been shifted exactly by the required amount.

If each of the disks g is displaced by a different specific amount, all balls b can be pushed back into their cavity, which happens when the key is now turned further and the drum c is turned. This rotation causes the bolt to move and the lock to open.

The lock is provided with disks g of various designs, the number of which corresponds to the number and arrangement of the balls b. In the embodiment shown, a row of disks, to which the topmost disk belongs, can be moved from right to left, another row from left to right and a third row from bottom to top. These different displacements of the disks g are achieved by special training of key attacks, not shown. An auxiliary disk, namely the lowermost disk I of the exemplary embodiment, is circular and is provided on its circumference with incisions η which correspond to the incisions m of the rectangular disks, but the edges of which form inclined surfaces which inward. As a result of the pressure exerted by the key, the pistons r force the pistons r to return to their normal closed position in the event of a breakage of one of the springs s of the pistons r when the balls are again facing the recesses d.

The balls b are expediently arranged at different heights in the drum c. They can also be replaced by rolls of the same composition which are less or just as thick as the movable inner drum.

The device is protected by a cover φ made of hardened steel, which is fastened with hardened screws.

The secure locking, which is achieved by the balls or rollers arranged in this way, prevents any drilling into the locking devices of the lock from the outside; because the tool would break when hitting the locking balls or rollers.
