Description

Titel: Schutzeinrichtung für ein Schloss gegen Manipulation des Schlosses  Title: Protective device for a lock against manipulation of the lock
Beschreibung description
Die vorliegende Erfindung betrifft eine Schutzeinrichtung für ein Schloss gegen Manipulation des Schlosses, welches Schloss wenigstens ein Sperrelement aufweist, das durch eine Öffnung in einem Stülp des Schlosses in eine Schließposition aus dem Schloss hervorbewegbar und in eine Öffnungsposition in das Schloss zurückbewegbar ist. The present invention relates to a protective device for a lock against manipulation of the lock, which lock has at least one locking element, which can be moved out through an opening in a Stülp of the lock in a closed position from the lock and moved back into an open position in the castle.
Schlösser für Türen, Tore, Fenster und dergleichen können manipuliert werden, indem mit einem Manipulationsgegenstand auf die Schließme- chanik innerhalb des Schlosses eingewirkt wird. Der Manipulationsgegenstand kann durch die Öffnung im Stülp in das Schloss eingeführt werden, da zwischen dem Sperrelement und der Öffnung ein Spalt gebildet ist. Wird als Manipulationsgegenstand ein Federdraht oder vorzugsweise ein Federblech verwendet, kann insbesondere bei nicht überfalzten Türen mit dem Manipulationsgegenstand leicht auf die Rückschiebesperre des Sperrelementes, insbesondere auf die Zuhaltung, eingewirkt werden. Ist die Rückschiebesperre des Sperrelementes, beispielsweise eines Schlossriegels oder einer Schlossfalle, aufgehoben, kann dieses in die Öffnungsposition des Schlosses zurückgeführt werden, und eine Tür kann unerlaubt passiert werden. Locks for doors, gates, windows and the like can be manipulated by acting with a manipulation object on the Schließme- mechanism within the castle. The manipulation object can be inserted into the lock through the opening in the cover, since a gap is formed between the locking element and the opening. If a spring wire or preferably a spring plate is used as the manipulation object, the non-rebated doors can easily be acted upon by the manipulation object on the reverse slide lock of the blocking element, in particular on the tumbler. If the push-back lock of the blocking element, for example a lock bolt or a lock latch, is released, this can be returned to the opening position of the lock, and a door can be passed without authorization.
Der Spalt zwischen dem Sperrelement und der Öffnung entsteht insbesondere dadurch, dass eine mehr oder weniger große Spielpassung zwischen dem Sperrelement und der Öffnung erforderlich ist. Die Öffnung im Stülp dient häufig als Führung des beweglichen Sperrelementes, das beispielsweise einen Riegel oder eine Falle darstellen kann. Zudem gleicht die Spielpassung Fertigungstoleranzen der einzelnen Bauteile aus, wodurch der Spalt ein laterales Maß von beispielsweise 0,5 mm erreichen kann. Gegen die Manipulationsmöglichkeit der Schließmechanik innerhalb des Schlosses bieten einfache Schlösser keine Vorkehrungen, so dass diese in niedrigen Einbruchsschutzklassen eingeordnet sind. Höherwertige Schlösser weisen Sperrelemente auf, die geometrisch derart ausgeführt sind, dass der Spalt zwischen dem Sperrelement und der Öffnung wenigs- tens teilweise abgedeckt sein kann. Beispielsweise kann ein Sperrelement einen Sperrelementschaft mit einem kleineren Querschnitt und einen Sperrelementkopf mit einem größeren Querschnitt aufweisen. Im Übergang zwischen dem Sperrelementschaft und dem Sperrelementkopf kann der Sperrelementkopf eine Art kragenartige Anformung besitzen, die je- doch die Fertigung des Sperrelementes erheblich erschwert. The gap between the locking element and the opening is created in particular by the fact that a more or less large clearance between the locking element and the opening is required. The opening in Stülp often serves as a guide of the movable locking element, which may for example represent a bolt or a trap. It also resembles the clearance fit manufacturing tolerances of the individual components, whereby the gap can reach a lateral dimension of, for example, 0.5 mm. Against the possibility of manipulation of the locking mechanism within the castle simple locks provide no precautions, so that they are classified in low burglary protection classes. Higher-quality locks have locking elements which are designed geometrically such that the gap between the blocking element and the opening can be at least partially covered. For example, a blocking element may have a blocking element shaft with a smaller cross section and a blocking element head with a larger cross section. In the transition between the blocking element shaft and the blocking element head, the blocking element head can have a kind of collar-like formation, which, however, makes the production of the blocking element considerably more difficult.
Insbesondere ist nachteilig, dass die speziell mit einem Manipulationsschutz ausgeformten Sperrelemente aufwendig hergestellt werden müssen, beispielsweise durch Gießen, Prägen, Umformen oder dergleichen. Die Bearbeitung der Führungsflächen, die zur Führung des Sperrelementes in der Öffnung des Stulpes dienen, wird im besonderen Maße durch Anformungen zur Bildung eines Manipulationsschutzes erschwert, da diese nicht mehr ganzflächig eben sind. Ein spanendes Nacharbeiten ist jedoch in der Regel erforderlich, da nur so ausreichend glatte und maßge- naue Führungsflächen am Sperrelement herstellbar sind. Das Nacharbeiten wird bei hochwertigen Riegeln aus Edelstahl gleichzeitig zur Oberflächenveredelung benutzt, z. B. durch Schleifen, Satinieren, Polieren und dergleichen. Es ist folglich die Aufgabe der vorliegenden Erfindung, eine Schutzeinrichtung für ein Schloss gegen Manipulation des Schlosses zu schaffen, die einfach herstellbar ist und ein hohes Maß an Sicherheit bietet. Diese Aufgabe wird ausgehend von einer Schutzeinrichtung für ein Schloss gegen eine Manipulation des Schlosses gemäß dem Oberbegriff des Anspruches 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben. In particular, it is disadvantageous that the locking elements formed in particular with a manipulation protection have to be manufactured consuming, for example by casting, embossing, forming or the like. The processing of the guide surfaces, which serve to guide the blocking element in the opening of the Stulpes is made more difficult by formations to form a manipulation protection, as they are no longer flat over the entire surface. However, a reworking is usually required because only so sufficiently smooth and dimensionally accurate guide surfaces on the locking element can be produced. The reworking is used for high quality stainless steel bars at the same time for surface refinement, z. B. by grinding, satin, polish and the like. It is therefore the object of the present invention to provide a guard for a lock against manipulation of the lock, which is easy to manufacture and offers a high level of security. This object is achieved on the basis of a protective device for a lock against manipulation of the lock according to the preamble of claim 1. Advantageous developments of the invention are specified in the dependent claims.
Die Erfindung schließt die technische Lehre ein, dass wenigstens ein Schutzelement am Sperrelement angeordnet ist, so dass ein zwischen dem Sperrelement und der Öffnung gebildeter Spalt überdeckt ist. The invention includes the technical teaching that at least one protective element is arranged on the blocking element, so that a gap formed between the blocking element and the opening is covered.
Ist erfindungsgemäß ein Schutzelement am Sperrelement angeordnet, so ist der zwischen dem Sperrelement und der Öffnung gebildete Spalt derart weit überdeckt, dass durch den Spalt ein Manipulationsgegenstand nicht mehr in das Schloss eingeführt werden kann. Wird versucht, einen Mani- pulationsgegenstand durch den Spalt zu bewegen, stößt dieser gegen das Schutzelement an, und es ist unmöglich, den Manipulationsgegenstand weiter in das Innere des Schlosses hinein zu bewegen. Das Schutzelement ist erfindungsgemäß als einzelnes Bauteil ausgeführt, das am Sperrelement angeordnet werden kann. Folglich kann das Sperrelement aus einfachen Flachmaterialien gefertigt werden, wobei die Nacharbeit der Führungsflächen durch einfache spanende Bearbeitungsvorgänge erfolgen kann, da diese ganzflächig eben sind, da keine Anformungen zur Bildung eines Manipulationsschutzes eine Flachbearbeitung stören könnten. Das Sperrelement kann einen Sperrelementschaft und einen Sperrelementkopf aufweisen, wobei das Schutzelement im Bereich des Übergangs vom Sperrelementschaft zum Sperrelementkopf am Sperrelement angeordnet ist. Der Sperrelementkopf bildet den Teil des Sperrelementes, der aus dem Stülp des Schlosses hervorspringen kann, wenn das Sperrele- ment in die Schließposition bewegt wird. Der Sperrelementschaft bildet den Teil des Sperrelementes, der in Richtung zur Innenseite des Schlosses weist und an den die Schließmechanik angreift, um die Bewegung zwischen der Schließposition und der Öffnungsposition in das Sperrelement einzuleiten. Mit besonderem Vorteil kann das Schutzelement an der Stelle am Sperrelement angeordnet werden, an der der Sperrelementschaft in den Sperrelementkopf übergeht. Diese Übergangsstelle befindet sich etwa rückseitig des Stulpes, wenn das Sperrelement in der Schließposition aus dem Schloss hervorbewegt ist. Folglich befindet sich auch das Schutzelement rückseitig am Stülp, und ein Zugang zur Innenseite des Schlosses durch den Spalt ist unmittelbar hinter dem Stülp unterbrochen, wenn das Sperrelement zur Einnahme der Schließposition aus dem Schloss hervorbewegt ist. If, according to the invention, a protective element is arranged on the blocking element, then the gap formed between the blocking element and the opening is covered to such an extent that a manipulation object can no longer be introduced into the castle through the gap. Attempting to move a manipulation object through the gap will strike the protective element and it will be impossible to move the manipulative object further into the interior of the lock. The protective element is designed according to the invention as a single component which can be arranged on the blocking element. Consequently, the locking element can be made of simple flat materials, wherein the reworking of the guide surfaces can be done by simple machining operations, since they are flat over the entire surface, since no protrusions to form a tamper protection could interfere with a flat machining. The blocking element may have a blocking element shaft and a blocking element head, wherein the protective element is arranged in the region of the transition from the blocking element shaft to the blocking element head on the blocking element. The locking element head forms the part of the locking element which can protrude from the turnout of the lock when the locking element is moved into the closed position. The blocking element shaft forms the part of the blocking element which points in the direction of the inside of the lock and on which the locking mechanism engages, in order to control the movement between the closed position and the open position in the blocking element initiate. With particular advantage, the protective element can be arranged at the location on the blocking element, at which the blocking element shaft merges into the blocking element head. This transition point is located approximately at the back of the Stulpes when the blocking element is moved out of the lock in the closed position. Consequently, the protective element is also located on the back of the cover, and access to the inside of the lock through the gap is interrupted immediately behind the Stülp when the locking element for taking the closed position is moved out of the lock.
Der Sperrelementschaft kann einen kleineren Querschnitt aufweisen als der Sperrelementkopf und im Bereich des Übergangs vom Sperrelementschaft zum Sperrelementkopf eine Sperrelementkante bilden, wobei das Schutzelement aus Richtung des Sperrelementschaftes gegen die Sperrelementkante zur Anlage gebracht ist. Der Querschnitt des Sperrelementes kann einem Rechteckquerschnitt entsprechen, und der Rechteckquerschnitt des Sperrelementkopfes weist größere Kantenlängen auf als die Kantenlängen des Rechteckquerschnittes des Sperrelementschaftes. Da- durch entsteht eine Sperrelementkante mit einer Kantenfläche, die sich quer zur Bewegungsrichtung des Sperrelementes erstreckt. Gegen diese Kantenfläche kann das Schutzelement zur Anlage gebracht sein. Hierzu kann das Schutzelement einen Durchgang aufweisen, durch den das Sperrelement und insbesondere der Sperrelementschaft hindurchgeführt ist. Mit besonderem Vorteil kann das Schutzelement das Seitenverhältnis der Kantenlängen des Rechteckquerschnittes vom Sperrelement nachbilden, und ein am Sperrelement angebrachtes Schutzelement bildet einen Kragen, der den Querschnitt des Sperrelementes umgibt. Mit Vorteil kann das Schutzelement das Sperrelement wenigstens teilweise und vorzugsweise vollständig umschließen, so dass der Spalt zwischen dem Sperrelement und der Öffnung vollumfänglich überdeckt ist. Folglich kann von keiner Seite ein Manipulationsgegenstand in den Spalt zwischen dem Sperrelement und der Öffnung im Stülp eingeführt werden. Insbesondere bei Sperrelementen, die einen rechteckigen Grundquerschnitt besitzen, kann das Schutzelement so ausgeführt sein, dass das Sperr- element vollumfänglich überdeckt ist. Ein derartiges Schutzelement weist einen Durchgang auf, durch den sich das Sperrelement folglich hindurch erstreckt. Besondere Schutzwirkung erreicht ein Schutzelement, welches an der Seite des Sperrelementes angeordnet ist, die in Richtung zu einem freien Türspalt weist. The blocking element shaft can have a smaller cross section than the blocking element head and form a blocking element edge in the region of the transition from the blocking element shaft to the blocking element head, the protective element being brought into contact with the blocking element edge from the direction of the blocking element shaft. The cross section of the blocking element may correspond to a rectangular cross section, and the rectangular cross section of the locking element head has larger edge lengths than the edge lengths of the rectangular cross section of the blocking element shaft. This results in a blocking element edge with an edge surface which extends transversely to the direction of movement of the blocking element. Against this edge surface, the protective element can be brought to bear. For this purpose, the protective element may have a passage through which the blocking element and in particular the blocking element shaft is guided. With particular advantage, the protective element can simulate the aspect ratio of the edge lengths of the rectangular cross section of the blocking element, and a protective element attached to the blocking element forms a collar which surrounds the cross section of the blocking element. Advantageously, the protective element at least partially and preferably completely surround the blocking element, so that the gap between the blocking element and the opening is completely covered. consequently No manipulation object can be introduced into the gap between the blocking element and the opening in the cover from either side. In particular, in blocking elements which have a rectangular basic cross-section, the protective element can be designed so that the locking element is completely covered. Such a protective element has a passage through which the blocking element consequently extends. Special protection achieves a protective element, which is arranged on the side of the blocking element, which points in the direction of a free door gap.
Nach einer möglichen vorteilhaften Ausführungsform der vorliegenden erfindungsgemäßen Schutzeinrichtung kann das Schutzelement am Sperrelement verrastet, verclipst, verschraubt, verschweißt, verlötet, aufge- presst und/oder an das Sperrelement mittels Kunststoffspritzguss ange- spritzt sein. Um eine weitere Erhöhung der Schutzwirkung gegen eine Manipulation zu erziehen, aber auch um einen Verschleißschutz des Schutzelementes zu erzielen, das gegen die Innenseite des Stulpes als Anschlag des Sperrelementes dienen kann, kann das Schutzelement aus einem gehärteten Stahl hergestellt sein. According to a possible advantageous embodiment of the present protective device according to the invention, the protective element can be latched, clipped, screwed, welded, soldered, pressed on and / or pressed onto the blocking element by means of plastic injection molding on the blocking element. In order to further increase the protective effect against manipulation, but also to achieve wear protection of the protective element, which can serve against the inside of the Stulpes as a stop of the blocking element, the protective element may be made of a hardened steel.
Das Schutzelement kann ferner aus dem gleichen Werkstoff hergestellt sein, wie auch das Sperrelement selbst. Weiterführend kann das Schutzelement aus einem Kunststoffmaterial hergestellt sein, welches an das Sperrelement angespritzt wird. Hierfür kann das Sperrelement Aufnahmegeometrien aufweisen, um einen geometrischen Formschluss zwischen dem Sperrelement und dem angespritzten Kunststoff- Schutzelement zu bilden. Insbesondere jedoch kann das Schutzelement am Sperrelement mechanisch angebracht werden, wobei die Verbindungsstruktur zwischen dem Schutzelement und dem Sperrelement hin- reichend belastbar ausgeführt ist, um zu vermeiden, dass mittels des Manipulationsgegenstandes das Schutzelement aus seiner Position am Sperrelement gelöst werden kann. Das Schutzelement kann aus einem Blechmaterial mittels Stanz-Biegeverfahren hergestellt sein, oder das Schutzelement ist mittels eines Metall-Druckgussverfahrens hergestellt. Furthermore, the protective element may be made of the same material as the blocking element itself. In addition, the protective element may be made of a plastic material which is injection-molded onto the blocking element. For this purpose, the blocking element can have receiving geometries in order to form a geometrical positive connection between the blocking element and the molded plastic protective element. In particular, however, the protective element can be mechanically attached to the blocking element, wherein the connecting structure between the protective element and the blocking element is made sufficiently resilient in order to avoid that the protective element can be released from its position on the blocking element by means of the manipulation object. The protective element may consist of a Sheet metal material can be produced by stamping-bending process, or the protective element is produced by means of a metal die-casting process.
Das Sperrelement des Schlosses mit der erfindungsgemäßen Schutzein- richtung kann verschiedenartig ausgeführt sein. Beispielsweise kann das Sperrelement als Schlossriegel und/oder als Schlossfalle des Schlosses ausgeführt sein. Ein Schloss weist regelmäßig einen Schlossriegel auf, welcher über einen Schließzylinder zwischen der aus dem Schloss hervorspringenden Schließposition und in das Schloss zurückgezogenen Öff- nungsposition bewegt wird. Folglich dient der Schlossriegel zum Verriegeln einer Tür, ohne dass diese lediglich durch einen Türdrücker geöffnet werden kann. Das Sperrelement kann auch als Schossfalle ausgeführt sein, welche nach regelmäßiger Bauart eines Schlosses mittels einer Handhabe zwischen der Schließposition und der Öffnungsposition beweg- bar ist, wobei eine Bewegung der Schlossfalle grundsätzlich auch über einen Schließzylinder erfolgen kann. Schlossfallen sind zumeist mittels eines Federelementes in die Schließposition vorgespannt, wobei ferner Schlösser bekannt sind, die zum Verriegeln des Schlosses mittels eines Schließzylinders die Schlossfalle in der Schließposition arretieren, indem eine Rückschiebesperre der Schlossfalle aktiviert wird. Das erfindungsgemäße Schutzelement kann unabhängig von der Ausführungsform des Sperrelementes als Schlossriegel oder als Schlossfalle an diesem angeordnet sein. Das Sperrelement kann in der Öffnung im Stülp linear bewegt, rotatorisch bewegt oder entlang einer Bahnkurve bewegt sein. Linear bewegte Sperrelemente weisen meist einen rechteckigen Querschnitt auf und besitzen eine längliche Erstreckung, die unterteilbar ist in den Sperrelementschaft im inneren Bereich des Schlosses und den Sperrelementkopf, der in der Sperrposition aus dem Stülp hervorbewegbar ist. Ferner sind rotatorisch bewegte oder entlang einer Bahnkurve bewegte Sperrelemente bekannt, die um eine Schwenkachse schwenken können, die im Schloss ortsfest eingebracht ist oder die in einer Bahn geführt werden können, um aus dem Stülp heraus in die Schließposition zu gelangen. Erfindungsgemäß kann das Schutzelement der Ausführungsart des Sperrelementes ange- passt sein. Die Abdeckung des Spaltes erfolgt insbesondere dann, wenn das Sperrelement in der Schließposition aus dem Stülp herausgefahren ist und das Schutzelement ist der geometrischen Form des Sperrelementes angepasst. The blocking element of the lock with the protective device according to the invention can be embodied in various ways. For example, the blocking element can be designed as a lock bolt and / or as a latch of the lock. A lock regularly has a lock bolt, which is moved via a lock cylinder between the locking position protruding from the lock and the opening position retracted into the lock. Consequently, the lock bolt is used to lock a door, without this can only be opened by a door handle. The blocking element can also be designed as a lap trap, which can be moved according to the regular design of a lock by means of a handle between the closed position and the open position, whereby a movement of the lock latch can in principle also take place via a lock cylinder. Lock traps are usually biased by a spring element in the closed position, further locks are known, which lock the lock latch in the closed position to lock the lock by means of a lock cylinder by a reverse slide lock the lock latch is activated. The protective element according to the invention can be arranged independently of the embodiment of the blocking element as a lock bolt or as a lock latch on this. The blocking element can be moved linearly in the opening in the Stülp, rotationally moved or moved along a trajectory. Linearly moving blocking elements usually have a rectangular cross-section and have an elongated extension which is subdivided into the blocking element shaft in the inner region of the lock and the blocking element head, which can be moved out of the step in the blocking position. Furthermore, rotationally moving or along a trajectory moving blocking elements are known which can pivot about a pivot axis which is stationary in the castle is introduced or can be performed in a lane to get out of the Stülp out in the closed position. According to the invention, the protective element can be adapted to the embodiment of the blocking element. The cover of the gap takes place in particular when the blocking element has moved out of the Stülp in the closed position and the protective element is adapted to the geometric shape of the blocking element.
Ist das Sperrelement als Schwenkriegel ausgeführt und um eine Schwenkachse im Schloss drehbar, so können zwei Schutzelemente vorgesehen sein, die seitlich aus Richtung der Schwenkachse beidseitig am Sperrelement anordbar sind und eine kragenförmige Anformung am Schwenkriegel bilden. Die Schutzelemente können schalenartig ausgeführt sein, und derart beidseitig am Sperrelement angeordnet werden, dass die Schutzelemente das Sperrelement wenigstens in dem Bereich umschließen, der auch in der Schließposition des Sperrelementes im Schloss verbleibt. Dabei bilden die schalenartigen Schutzelemente einen Kragen, der den Teil des Sperrelementes kragenförmig umschließt, der in der Schließposition aus dem Stülp des Schlosses hervorspringt. In dieser Position grenzt der durch die Schutzelemente gebildete Kragen innenseitig gegen den Stülp des Schlosses an, so dass die gewünschte Sicherheit gegen eine Manipulation der Schließmechanik innerhalb des Schlosses geschaffen ist. Das Sperrelement kann einen Achsbolzen aufweisen, der sich in der Schwenkachse erstreckt und die mechanische Aufnahme des als Schwenkriegel ausgeführten Sperrelementes bildet. Die Achsbolzen können derart ausgeführt sein, dass die seitlich an das Sperrelement anliegenden Schutzelemente mit dem Sperrelement eine bauliche Einheit bil- den, und nur durch Überwindung erheblicher mechanischer Kräfte von diesem gelöst werden können. Insbesondere entsteht die kragenförmige Anformung der Schutzelemente am Schwenkriegel auf der Seite des Schwenkriegelrückens, da der Spalt zwischen dem Schwenkriegel und dem Stülp des Schlosses im Bereich des Schwenkriegelrückens am größten ist. Diese kann bei einem Schwenkriegel, der um die Schwenkachse im Schloss drehbar ist, mit gleich bleibendem Abstand der Öffnung einen konstanten Spalt bilden, der sich über dem gesamten Bewegungsweg des Sperrelementes nicht ändert. Weiterführend kann das Sperrelement als Schwenkriegel mit einem Schwenkriegelrücken ausgeführt sein, wobei das Schutzelement als Einsetzelement ausgebildet und auf dem Schwenkriegelrücken angeordnet ist. Das Einsetzelement kann vorzugsweise stoffschlüssig oder formschlüssig am Sperrelement angeordnet sein, und sich lediglich über den Schwenkriegelrücken erstrecken oder das Einsetzelement umschließt den Schwenkriegel wenigstens ebenfalls in seitlicher Richtung. If the blocking element is designed as a pivot bolt and rotatable about a pivot axis in the lock, then two protective elements can be provided, which can be arranged laterally from the direction of the pivot axis on both sides of the blocking element and form a collar-shaped projection on the pivot bolt. The protective elements may be designed shell-like, and be arranged on both sides of the blocking element such that the protective elements enclose the blocking element at least in the region which remains in the closed position of the blocking element in the lock. The shell-like protective elements form a collar, which surrounds the part of the blocking element in a collar shape, which protrudes in the closed position from the Stülp of the castle. In this position, the collar formed by the protective elements on the inside adjacent to the Stülp of the castle, so that the desired security against manipulation of the locking mechanism is created within the castle. The blocking element may have an axle which extends in the pivot axis and forms the mechanical receptacle of the locking element designed as a pivot bolt. The axle bolts can be designed in such a way that the protective elements resting laterally on the blocking element form a constructional unit with the blocking element, and can only be detached therefrom by overcoming considerable mechanical forces. In particular, the collar-shaped formation of the protective elements on the pivot bolt on the side of the pivot bolt back, since the gap between the pivot bolt and the Stülp of the lock in the region of the pivot lock back is greatest. This can at a pivot bolt which is rotatable about the pivot axis in the lock, with constant spacing of the opening form a constant gap, which does not change over the entire path of movement of the blocking element. Furthermore, the blocking element can be designed as a pivot bolt with a pivot bolt back, wherein the protective element is designed as an insertion element and is arranged on the pivot bolt back. The insertion element may preferably be cohesively or positively arranged on the blocking element, and extend only over the pivot bolt back or the insertion element surrounds the pivot bolt at least also in the lateral direction.
Nach einer noch weiteren vorteilhaften Ausführungsform kann das Schutzelement mit einem elektrischen Schaltmittel zusammenwirken, so dass wenigstens eine Erkennung der Schließposition des Sperrelementes durch eine Steuereinheit ermöglicht ist. Das elektrische Schaltmittel kann beispielsweise einen Schalter, vorzugsweise einen Mikroschalter, bilden, mit welchem das Schutzelement mechanisch zusammenwirkt, um das elektrische Schaltmittel zu aktivieren. Beispielsweise kann damit eine In- formation an die Steuereinheit übermittelt werden, ob sich das Sperrelement in der Schließposition oder in der Öffnungsposition befindet. According to yet another advantageous embodiment, the protective element can cooperate with an electrical switching means, so that at least one detection of the closing position of the blocking element is made possible by a control unit. The electrical switching means may for example form a switch, preferably a microswitch, with which the protective element cooperates mechanically to activate the electrical switching means. For example, information can thus be transmitted to the control unit as to whether the blocking element is in the closed position or in the open position.
Mit noch weiterem Vorteil kann das Schutzelement in der aus dem Schloss hervorbewegten Position schlossinnenseitig gegen den Stülp an- schlagen, wobei das Schutzelement derart ausgeführt ist, dass das Schutzelement bei Anschlag an den Stülp eine Dämpfungswirkung schafft. Insbesondere dann, wenn das Schutzelement aus einem Kunststoffmate- rial ausgeführt ist, kann die vorteilhafte Dämpfungswirkung erzielt werden. Ferner kann das Schutzelement eine Kunststoff- oder Gummieinlage aufweisen, die einen innenseitigen Anschlag gegen den Stülp dämpft. Wird das Sperrelement in die Schließposition bewegt und springt dieses insbesondere federunterstützt in die Schließposition, so kann ein Anschlag des Schutzelementes gegen die Innenseite des Stulpes mit einer Dämpfungswirkung insbesondere Schließgeräusche dämpfen. With even further advantage, the protective element can hit the inside of the lock in the position moved out of the lock, whereby the protective element is embodied in such a way that the protective element creates a damping effect when it touches the cover. In particular, when the protective element made of a plastic mate- Rial is executed, the advantageous damping effect can be achieved. Furthermore, the protective element may have a plastic or rubber insert, which dampens an inside stop against the Stülp. If the blocking element is moved into the closed position and this jumps in particular spring assisted in the closed position, so a stop of the protective element against the inside of the Stulpes with a damping effect in particular dampen closing noise.
Die Aufgabe der vorliegenden Erfindung wird ferner gelöst durch ein Schloss mit einem Sperrelement, das durch eine Öffnung in einem Stülp des Schlosses in eine Schließposition aus dem Schloss hervorbewegbar und in eine Öffnungsposition in das Schloss zurückbewegbar ist, wobei am Sperrelement ein Schutzelement angeordnet ist, so dass ein zwischen dem Sperrelement und der Öffnung gebildeter Spalt überdeckt ist, um eine Schutzeinrichtung gegen eine Manipulation des Schlosses zu schaffen. The object of the present invention is further achieved by a lock having a blocking element, which can be moved out of the lock through an opening in a slot of the lock into a closed position and moved back into an opening position into the lock, wherein a protective element is arranged on the blocking element in that a gap formed between the blocking element and the opening is covered in order to provide a protective device against manipulation of the lock.

Protective element, a side view of the arrangement of a locking element in a lock in a protruding from the Stülp closed position, 4 shows a locking element, which is designed as a pivot bolt and two protective elements according to a further embodiment and FIG. 5 shows a further embodiment of a pivot bolt in a lock, wherein a further embodiment of a protective element is shown.
Figur 1 zeigt ein Ausführungsbeispiel einer Schutzeinrichtung gemäß der vorliegenden Erfindung. Dargestellt ist ein Sperrelement 1 1 , das als Schlossriegel mit einem rechteckigen Querschnitt ausgeführt ist und in einer Öffnung eines Stulpes des Schlosses längsbeweglich geführt ist. Das Sperrelement 1 1 weist einen Sperrelementschaft 16 auf, an den sich ein Sperrelementkopf 17 anschließt. Der Sperrelementschaft 16 bildet den Teil des Sperrelementes 1 1 , der sowohl in der Öffnungsposition als auch in der Schließposition des Sperrelementes 1 1 innenseitig im Schloss, d. h., hinter dem Stülp, verbleibt. Hingegen springt der Sperrelementkopf 17 aus dem Stülp des Schlosses hervor, wenn das Sperrelement 1 1 in die Schließposition zum Schließen beispielsweise einer Tür bewegt wird. Figure 1 shows an embodiment of a protective device according to the present invention. Shown is a locking element 1 1, which is designed as a lock bolt with a rectangular cross-section and is longitudinally movably guided in an opening of a cuff of the castle. The blocking element 1 1 has a blocking element shaft 16, to which a blocking element head 17 connects. The blocking element shaft 16 forms the part of the blocking element 1 1, both in the open position and in the closed position of the blocking element 1 1 inside the castle, d. h., behind the Stülp, remains. On the other hand, the locking element head 17 protrudes from the Stülp of the castle, when the locking element 1 1 is moved to the closed position for closing, for example, a door.
Im Bereich des Überganges vom Sperrelementschaft 16 zum Sperrelementkopf 17 ist erfindungsgemäß ein Schutzelement 14 angeordnet. Das Schutzelement 14 ist als Einzelteil ausgeführt und kann insbesondere gegen eine Sperrelementkante 18 zur Anlage gebracht werden, die den Übergangsbereich zwischen dem Sperrelementschaft 16 und dem Sperrelementkopf 17 bildet. Die Darstellung zeigt ein Schutzelement 14, welches eine kragenartige Umrandung des Querschnittes des Sperrelementkopfes 17 bildet. Der Kragen umrandet dabei den Querschnitt des Sperrelementkopfes 7 vollumfänglich. In the region of the transition from the blocking element shaft 16 to the blocking element head 17, a protective element 14 is arranged according to the invention. The protective element 14 is designed as a single part and can in particular be brought into abutment against a locking element edge 18, which forms the transition region between the blocking element shaft 16 and the blocking element head 17. The illustration shows a protective element 14, which forms a collar-like border of the cross-section of the blocking element head 17. The collar surrounds the cross section of the blocking element head 7 in full.
Figur 2 zeigt das Schutzelement 14 als Einzelteil in einer perspektivischen Ansicht. Um den Sperrelementschaft 16 durch das Schutzelement 14 hindurchzuführen, weist dieses einen Durchgang 19 auf, der das Schutzelement 14 mittig durchsetzt. Die im Schutzelement 14 gezeigte Aussparung 25 bildet eine Vertiefung im Schutzelement 14, und der Querschnitt des Sperrelementkopfes 17 kann in die Aussparung 25 im Schutzelement 14 einrasten, so dass die Sperrelementkante 18 des Sperrelementes 1 1 gegen die Bodenfläche der Aussparung 25 zur Anlage kommt. Figure 2 shows the protective element 14 as a single part in a perspective view. To the blocking element shaft 16 through the protective element 14th lead, this has a passage 19 which passes through the protective element 14 centrally. The recess 25 shown in the protective element 14 forms a recess in the protective element 14, and the cross section of the blocking element head 17 can engage in the recess 25 in the protective element 14, so that the locking element edge 18 of the blocking element 1 1 comes to rest against the bottom surface of the recess 25.
Figur 3 zeigt die Anordnung des Sperrelementes 1 1 in einem Schloss 10, das vorderseitig durch den Stülp 13 begrenzt ist. Das Sperrelement 1 1 ist auch in diesem Ausführungsbeispiel als Schlossriegel ausgeführt und linear bewegbar, wobei die Bewegungsrichtung durch einen Doppelpfeil angedeutet ist. In der quer geschnittenen Ansicht ist das Schutzelement 14 in angrenzender Anlage an die Sperrelementkante 18 gezeigt, die den Übergang zwischen dem Sperrelementschaft 16 und dem Sperrelement- köpf 17 bildet. Das Sperrelement 1 1 ist in der aus dem Stülp 13 hervorspringenden Schließposition gezeigt, und das Schutzelement 14 grenzt an die Innenseite des Stulpes 13 an. Zwischen dem Sperrelementkopf 17 und der Öffnung 12 im Stülp 13 ist ein Spalt 15 gebildet, wobei der Spalt 15 keinen durchgängigen Bereich in Richtung zur Innenseite des Schlosses 10 bildet, da dieser durch das Schutzelement 14 unterbrochen ist. Würde mit einem Manipulationsgegenstand durch den Spalt 15 in das Innere des Schlosses 10 eingedrungen werden, so wird das Schutzelement 14 eine Barriere bilden, und das Innere des Schlosses 15 ist vor einem Manipulationsgegenstand geschützt. Das Schutzelement 14 kann auf verschiedene Weise vorzugsweise stoffschlüssig oder formschlüssig mit dem Sperrelement 1 1 verbunden sein. Lediglich beispielhaft ist eine Schweißung 26 gezeigt, über die das Schutzelement 14 stoffschlüssig am Sperrelement 1 1 angebracht ist. In Figur 4 ist in einer perspektivischen Ansicht ein weiteres Ausführungsbeispiel eines Sperrelementes 1 1 gezeigt, das als Schwenkriegel ausgebildet ist. Das Sperrelement 1 1 ist um eine Schwenkachse 20 drehbeweg- lieh im Schloss 10 aufgenommen und weist eine Vielzahl von plattenartigen Elementen auf, die in einer Paketanordnung den Körper des Sperrelementes 1 1 bilden und über Bolzen miteinander verbunden sind. Die Schwenkachse 20 wird durch einen Achsbolzen 24 gebildet, welcher Achsbolzen 24 als Schraubelement ausgeführt ist. Erfindungsgemäß sind zwei Schutzelemente 14 vorgesehen, die seitlich jeweils aus Richtung der Schwenkachse 20 beidseitig am Schwenkriegel angeordnet sind. Dabei bilden die Schutzelemente 14 eine kragenförmige Anformung 21 , die sich insbesondere über dem Schwenkriegelrücken 22 erstreckt. Die kragenförmige Anformung 21 ist jeweils auch seitlich des Teils des Schwenkriegels gebildet, der sich auch in der Schließposition des Schwenkriegels innenseitig im Schloss 10 befindet. Die Schutzelemente 14 sind schalenartig ausgeführt und umgreifen das Sperrelement 1 1 aus seitlicher Rich- tung. Die Schutzelemente 14 sind über den Achsbolzen 24 mit dem Sperrelement 1 1 verliersicher verschraubt. Figure 3 shows the arrangement of the locking element 1 1 in a lock 10, which is bounded on the front side by the Stülp 13. The blocking element 1 1 is also designed in this embodiment as a lock bolt and linearly movable, wherein the direction of movement is indicated by a double arrow. In the cross-sectional view, the protective element 14 is shown abutting the locking element edge 18, which forms the transition between the blocking element shaft 16 and the blocking element head 17. The blocking element 1 1 is shown in the protruding from the Stülp 13 closing position, and the protective element 14 adjacent to the inside of the Stulpes 13 at. Between the blocking element head 17 and the opening 12 in the stülp 13, a gap 15 is formed, wherein the gap 15 does not form a continuous region in the direction of the inside of the lock 10, since this is interrupted by the protective element 14. Would be penetrated with a manipulation object through the gap 15 into the interior of the lock 10, the protective element 14 will form a barrier, and the interior of the lock 15 is protected from a manipulation object. The protective element 14 may be connected in various ways preferably cohesively or positively with the blocking element 1 1. By way of example only, a weld 26 is shown over which the protective element 14 is integrally attached to the blocking element 11. 4 shows a perspective view of another embodiment of a locking element 1 1 is shown, which is designed as a pivot bolt. The blocking element 11 is rotatable about a pivot axis 20. borrowed in the lock 10 and has a plurality of plate-like elements which form the body of the blocking element 1 1 in a package arrangement and are connected to each other via bolts. The pivot axis 20 is formed by a pivot pin 24, which axle pin 24 is designed as a screw. According to the invention two protective elements 14 are provided, which are arranged laterally from the direction of the pivot axis 20 on both sides of the pivot bolt. In this case, the protective elements 14 form a collar-shaped projection 21, which extends in particular over the pivot bolt back 22. The collar-shaped Anformung 21 is also formed laterally of the part of the pivot bolt, which is also in the closed position of the pivot bolt inside the lock 10. The protective elements 14 are designed like a shell and surround the blocking element 1 1 from the lateral direction. The protective elements 14 are screwed captive over the axle 24 with the locking element 1 1.
Figur 5 zeigt eine quer geschnittene Ansicht durch ein Schloss 10 im Bereich des Stulpes 13. Das Sperrelement 1 1 ist ebenfalls als Schwenkriegel ausgeführt und im Schloss 10 um die Schwenkachse 20 drehbar gelagert. Im Stülp 13 ist die Öffnung 12 gezeigt, durch die das Sperrelement 1 1 in die Schließposition hervorspringen kann. Dabei entsteht zwischen dem Schwenkriegelrücken 22 und der Öffnung 12 der Spalt 15, der insbesondere zwischen dem Schwenkriegelrücken 22 und der oberen Seite der Öffnung 12 gebildet ist. Um diesen Spalt 15 als Einführkanal eines Manipulationsgegenstandes zur Einwirkung auf die Schließmechanik zu unterbrechen, ist ein Schutzelement 14 vorgesehen, welches als Einsetzelement 23 ausgeführt ist. Dieses ist auf der Seite des Schwenkriegelrückens 22 eingesetzt und beispielsweise im Schwenkriegel verschweißt oder ver- lötet. In der gezeigten Position befindet sich der Schwenkriegel in der Schließposition und springt aus dem Stülp 13 hervor. Dabei ist erkennbar, dass der Spalt 15 in Richtung zur Innenseite des Schlosses 10 durch das Einsetzelement 23 überdeckt ist. FIG. 5 shows a cross-sectional view through a lock 10 in the region of the cuff 13. The blocking element 11 is likewise designed as a pivot bolt and is rotatably mounted in the lock 10 about the pivot axis 20. In Stülp 13, the opening 12 is shown, through which the locking element 1 1 can jump into the closed position. In this case, between the pivot bolt back 22 and the opening 12 of the gap 15, which is formed in particular between the Schwenkriegelrücken 22 and the upper side of the opening 12. In order to interrupt this gap 15 as an insertion channel of a manipulation object for acting on the locking mechanism, a protective element 14 is provided, which is designed as an insertion element 23. This is inserted on the side of the pivot bolt back 22 and, for example, welded or soldered in the pivot bolt. In the position shown, the pivot bolt is in the closed position and protrudes from the Stülp 13. It can be seen that the gap 15 is covered in the direction of the inside of the lock 10 by the insertion element 23.
