Definitions
- the innovation relates to a lock protection device according to the preamble of protection claim 1.
- lock protection devices which are intended to prevent a lock cylinder from breaking off. These consist of a metal body which surrounds a part of the locking cylinder, namely the part which protrudes from the door plate, and within this body a plate is also made of metal, which has a slot for inserting the key into the lock. This plate is rotatably arranged.
- DE-OS 25 57 151 may be mentioned as an example of this.
- a rotatable cover, which is intended to prevent the lock cylinder from breaking off, is known from DE-OS 19 26 519.
- the innovation is therefore based on the task of creating a lock protection device which, on the one hand, makes it difficult to break open the lock or pull out the core and, on the other hand, enables the key to be inserted into the cylinder core in order to carry out the closing movement.
- this object is achieved in that the plate arranged in the hard metal body surrounding the lock cylinder can be displaced axially within the recess of this hard metal body by stops.
- the plate can be under an axial spring pressure, so that it always inevitably bears against the cylinder core or the housing during its axial displacement within the recess, thus avoiding any play between this plate and the core, so that a secure insertion of the key is guaranteed.
- the plate in the hard metal body can be screwed into the hard metal body by means of an internal thread on the recess of the hard metal body or an external thread on the plate, so that the plate is also in contact with the cylinder core. Even after a corresponding fixation of the plate from the inside, which prevents further screwing in or unscrewing, the necessary transition from the plate into the core for the key is then possible, and thus finally a correct closing.
- a schematic cross section and a front view through the lock protection device are shown in the figures.
- the lock protection device consists of a metal body 1 surrounding the lock cylinder, which has a recess 3.
- the plate 2 which is also made of metal, is rotatably arranged in this recess 3 and is axially displaceable, the displacement of which is limited by an outer stop 4 and an inner stop 5.
- the metal body 1 is applied from the outside to the lock cylinder and fastened there, in such a way that from the inside the cylinder core presses against the plate 2, which in turn is under the action of a spring 6 and is thus pressed against the core. This ensures that there is no play between the plate and the core and a secure insertion of the key is guaranteed.
- the metal body 1 is also shown in section and in the recess 3 there is the plate, which is provided here with the reference number 7.
- This plate has an external thread 8 while the recess of the metal body has an internal thread 9.
- the threaded plate has on its front side a rotatable second plate 7a which cannot be displaced in the axial direction relative to it.
- the connection between threaded plate 7 and plate 7a can be done, for example, by flanging 7b. In this way, the threaded plate 7 with plate 7a is axially displaceable within the recess of the metal body 1 and can thus be pressed against the cylinder core.
- An external stop 4 is also provided here, which prevents the plate from being unscrewed.

Abstract
Description
Die Neuerung betrifft eine Schloßschutzvorrichtung gemäß dem Oberbegriff des Schutzanspruchs 1.The innovation relates to a lock protection device according to the preamble of
Es sind verschiedene Arten von Schloßschutzvorrichtungen bekannt, die das Abbrechen eines Schließzylinders verhindern sollen. Diese bestehen aus einem Metallkörper, der einen Teil des Schließzylinders, und zwar den Teil der aus der Türplatte herausragt, umgibt, und innerhalb dieses Körpers ist eine Platte ebenfalls aus Metall angeordnet, die einen Schlitz zum Einführen des Schlüssels in das Schloß aufweist. Diese Platte ist drehbar angeordnet. Als Beispiel hierfür sei die DE-OS 25 57 151 erwähnt. Ebenfalls eine drehbare Abdeckung, die ein Abbrechen des Schließzylinders verhindern soll, ist aus der DE-OS 19 26 519 bekannt.Various types of lock protection devices are known which are intended to prevent a lock cylinder from breaking off. These consist of a metal body which surrounds a part of the locking cylinder, namely the part which protrudes from the door plate, and within this body a plate is also made of metal, which has a slot for inserting the key into the lock. This plate is rotatably arranged. DE-OS 25 57 151 may be mentioned as an example of this. A rotatable cover, which is intended to prevent the lock cylinder from breaking off, is known from DE-OS 19 26 519.
Es hat sich in der Praxis gezeigt, daß all diese Vorrichtungen in soweit den Nachteil haben, als nach dem Einbau bzw. dem Anschrauben der Abdeckung und dem eingeführten Zylinder insbesondere dem Kern des Zylinders ein Spielraum besteht, der das Einführen des Schlüssels in den Kern erschwert, weil durch entsprechende Anschläge am Schlüsselrücken nur ein vorgegebener Einschubweg für den Schlüssel zur Verfügung steht und dieser, wenn ein Spiel zwischen Kern und Abdeckung vorhanden ist, nicht ausreicht, um ein ordnungsgemäßes betätigen des Schlosses zu ermöglichen.It has been shown in practice that all these devices have the disadvantage that there is a margin after the installation or screwing of the cover and the inserted cylinder, in particular the core of the cylinder, which complicates the insertion of the key into the core , because with appropriate stops on the back of the key there is only a predetermined insertion path available for the key and, if there is play between the core and the cover, this is not sufficient to enable the lock to be operated properly.
Der Neuerung liegt daher die Aufgabe zugrunde, eine Schloßschutzvorrichtung zu schaffen, die einerseits ein Aufbrechen des Schlosses oder Herausziehen des Kernes erschwert und zum anderen ein siches Einführen des Schlüssels in den Zylinderkern zur Durchführung der Schließbewegung ermöglicht.The innovation is therefore based on the task of creating a lock protection device which, on the one hand, makes it difficult to break open the lock or pull out the core and, on the other hand, enables the key to be inserted into the cylinder core in order to carry out the closing movement.
Gelöst wird diese Aufgabe neuerungsgemäß dadurch, daß die in dem den Schloßzylinder umgebenden Hartmetallkörper angeordnete Platte durch Anschläge begrenzt axial innerhalb der Ausnehmung dieses Hartmetallkörpers verschiebbar ist.According to the innovation, this object is achieved in that the plate arranged in the hard metal body surrounding the lock cylinder can be displaced axially within the recess of this hard metal body by stops.
Nach einer Ausführung der Neuerung kann dabei die Platte unter einem axialen Federdruck stehen, so daß sie sich zwangsläufig bei ihrer axialen Verschiebung innerhalb der Ausnehmung immer am Zylinderkern bzw. am Gehäuse anlegt und damit jegliches Spiel zwischen dieser Platte und dem Kern vermieden wird, so daß ein sicheres Einführen des Schlüssels gewährleistet ist.According to an embodiment of the innovation, the plate can be under an axial spring pressure, so that it always inevitably bears against the cylinder core or the housing during its axial displacement within the recess, thus avoiding any play between this plate and the core, so that a secure insertion of the key is guaranteed.
Bei einer zweiten Ausführung der Neuerung ist die Platte in dem Hartmetallkörper mittels eines Innengewindes an der Ausnehmung des Hartmertallkörpers bzw. eines Außengewindes an der Platte in diesen einschraubbar, so daß ebenfalls eine Anlage der Platte am Zylinderkern gewährleistet ist. Auch damit ist dann nach einer entsprechenden Fixierung der Platte von innen, die ein weiteres Ein- oder Ausschrauben verhindert, der notwendige Übergang von der Platte in den Kern für den Schlüssel möglich und damit schließlich ein einwandfreies Schließen.In a second embodiment of the innovation, the plate in the hard metal body can be screwed into the hard metal body by means of an internal thread on the recess of the hard metal body or an external thread on the plate, so that the plate is also in contact with the cylinder core. Even after a corresponding fixation of the plate from the inside, which prevents further screwing in or unscrewing, the necessary transition from the plate into the core for the key is then possible, and thus finally a correct closing.
Die Neuerung soll nachfolgend anhand der Figuren, die diese Ausführungsbeispiele zeigen, erläutert werden. Dabei ist in den Figuren jeweils ein schematischer Querschnitt durch die Schloßschutzvorrichtung dargestellt.The innovation is to be explained below with reference to the figures which show these exemplary embodiments. A schematic cross section through the lock protection device is shown in the figures.
Dabei ist in den Figuren jeweils ein schematischer Querschnitt und eine Vorderansicht durch die Schloßschutzvorrichtung dargestellt.A schematic cross section and a front view through the lock protection device are shown in the figures.
In der Figur 1 besteht die Schloßschutzvorrichtung aus einem den Schloßzylinder umgebenden Metallkörper 1, der eine Ausnehmung 3 aufweist. In dieser Ausnehmung 3 ist drehbar die ebenfalls aus Metall bestehende Platte 2 angeordnet, die axial verschiebbar ist, wobei deren Verschiebung durch einen äußeren Anschlag 4 sowie einen inneren Anschlag 5 begrenzt wird. Der Metallkörper 1 wird von außen auf den Schließzylinder aufgebracht und dort befestigt, und zwar in der Art, daß von innen der Zylinderkern gegen die Platte 2 drückt, die ihrerseits unter der Wirkung einer Feder 6 steht und damit an den Kern angedrückt wird. Damit ist erreicht, daß kein Spiel zwischen der Platte und dem Kern vorhanden ist und es wird ein sichers Einführen des Schlüssels gewährleistet.In Figure 1, the lock protection device consists of a
Bei der Ausführung nach Fig. 2 ist ebenfalls der Metallkörper 1 im Schnitt dargestellt und in dessen Ausnehmung 3 befindet sich die Platte, die hier mit dem Bezugszeichen 7 versehen ist. Diese Platte weist ein Außengewinde 8 auf, während die Ausnehmung des Metallkörpers ein Innengewinde 9 aufweist. Die Gewindeplatte besitzt auf ihrer Frontseite eine drehbare und in Axialrichtung relativ zu ihr nicht verschiebbare zweite Platte 7a. Die Verbindung zwischen Gewindeplatte 7 und Platte 7a kann z.B. durch umbördeln geschehen 7b. Auf diese Weise ist die Gewindeplatte 7 mit Platte 7a innerhalb der Ausnehmung des Metallkörpers 1 axial verschiebbar und kann so gegen den Zylinderkern gedrückt werden.2, the
Ebenfalls hierbei ist vorgesehen ein äußerer Anschlag 4, der ein Herausdrehen der Platte verhindert. Nach der Fixierung der Platten 7, 7a in der Anschlagstellung am Zylinderkern besteht kein Spiel zwischen der Platte und der Kern, so daß auch hierbei ein sicheres Einführen des Schlüssels möglich ist und damit die beim Stand der Technik vorhandenen Nachteile, die zu einer Beeinträchtigung des Schließvorganges führen können, ausgeräumt werden, bei gleichzeitiger Sicherung des Schlosses gegen ein Aufbrechen.An
