Abstract

Two cylinder cores (16) contained in a two-part housing (2) operate a beard (6) via a coupling (7). The coupling has a dead turning angle so that, when one cylinder core (16) is turned by 360 degrees, the closing beard is turned by a smaller turning angle. The two housing parts are joined by an arm (18) above the lock screw hole (4). The arm is thicker between the housing parts as far as the periphery of a carrier for the coupling. The arm between the two housing parts has an upward protruding fitment (3) resting flat on the sides of the housing parts.

Description

Die Erfindung betrifft einen Einbau-Doppelschliesszylinder für ein Sicherheitsschloss, mit zwei in einem Gehäuse angeordneten Zylinderkernen, die über eine Kupplung einen Schliessbart betätigen, welche Kupplung einen toten Drehwinkel aufweist, derart, dass bei einer Drehung des einen Zylinderkerns um 360° der Schliessbart um einen kleineren Drehwinkel verdreht wird.The invention relates to a built-in double lock cylinder for a security lock, with two cylinder cores arranged in a housing and actuating a locking beard via a coupling, the coupling having a blind angle of rotation, such that when the one cylinder core is rotated through 360 ° the locking beard by one smaller angle of rotation is rotated.

Ein Schliesszylinder dieser Gattung ist aus der CH-A-519 645 bekannt geworden. Bei diesem ist das Gehäuse aus einem Stück gefertigt und im Bereich der Stulpschraubenbohrung verstärkt. Da bei diesem Schliesszylinder im Gehäuse eine Ausnehmung für den Mitnehmernocken des Schliessbartes nicht erforderlich ist, ist die Querschnittsfläche des Gehäuses an der Stelle der Stulpschraubenbohrung wesentlich weniger geschwächt als bisher. Somit ist es für einen Einbrecher schwieriger, mit einem geeigneten Werkzeug ein vorstehendes Ende des Doppelschliesszylinders festzuklemmen und das Zylindergehäuse an der durch die Stulpschraubenbohrung geschwächten Stelle zu brechen. Steht dem Einbrecher genügend Zeit zur Verfügung, kann ein solcher Messingdoppelschliess-zylinder in Folge einer Materialermüdung dennoch an der genannten geschwächten Stelle leicht gebrochen und das Schloss geöffnet werden. Es werden auch Ziehwerkzeuge angeboten, mit denen Doppelzylinder aus Messing entzweigerissen werden können.A locking cylinder of this type has become known from CH-A-519 645. In this case, the housing is made from one piece and reinforced in the area of the faceplate screw hole. Since a recess for the driver cam of the locking beard is not required in this locking cylinder in the housing, the cross-sectional area of the housing at the location of the faceplate screw hole is weakened considerably less than before. It is therefore more difficult for a burglar to clamp a protruding end of the double locking cylinder with a suitable tool and to weaken the cylinder housing to the one that is weakened by the faceplate screw hole Place to break. If the burglar has enough time, such a double brass lock cylinder can easily be broken at the weak point mentioned and the lock opened due to material fatigue. Drawing tools are also available with which double cylinders made of brass can be torn apart.

Der Erfinder hat sich die Aufgabe gestellt, einen Einbau-Doppelschliesszylinder der genannten Gattung zu schaffen, bei dem es noch wesentlich schwieriger ist, die Sperrorgane des Schliesszylinders gewaltsam mit Hilfsmitteln zu überwinden.The inventor has set himself the task of creating a built-in double locking cylinder of the type mentioned, in which it is even more difficult to overcome the locking elements of the locking cylinder by force with aids.

Die Aufgabe ist bei einem gattungsgemässen Doppelschliesszylinder dadurch gelöst, dass das Gehäuse zwei Gehäuseteile aufweist, die mit einem zwischen diesen Gehäuseteilen über der Stulpschraubenbohrung massiv verdickten Steg verbunden sind. Doppelschliesszylinder mit zwei Gehäuseteilen, die mit einem Steg verbunden sind, sind an sich bekannt. Bei diesen war aber bisher der Steg zwischen den Gehäuseteilen so ausgebildet, dass der Durchtritt des Mitnehmernockens des Schliessbartes zwischen den Gehäuseteilen nicht behindert ist. Um den Steg im Bereich der Stulpschraubenbohrung zu verstärken, ist schon vorgeschlagen worden, in den Steg ein Stahlseil einzulegen. Infolge der Flexibilität des Stahlseiles ist es bei dieser Ausführung kaum möglich, den Steg zu zerreissen. Beim erfindungsgemässen Doppelschliesszylinder ist der Steg zwischen den Gehäuseteilen über der Stulpschraube massiv verdickt. Da bei dem erfindungsgemässen Doppelschliesszylinder der Mitnehmer zwischen den Gehäuseteilen nicht hindurchtritt, ist die Verdickung des Stahlsteges so massiv ausgeführt, dass die Schwächung durch die Stulpschraubenbohrung bei weitem ausgeglichen ist. Der Steg kann damit im Bereich der Stulpschraubenbohrung nicht mehr bewegt werden und es ist deshalb auch bei einem lange andauernden Biegeversuch keine Materialermüdung zu erwarten. Durch die wesentlich massivere Verdickung des Steges ist zudem die Anlagefläche der Gehäuseteile an der Verdikkung grösser und damit ist die Beweglichkeit der einzelnen Teile weiter vermindert. Das Gehäuse bildet dadurch eine kompaktere und auch wesentlich stabilere Einheit. Ein Zerreissen des erfindungsgemässen Doppelschliesszylinders mit einem Ziehwerkzeug ist nicht möglich.The object is achieved in a generic double lock cylinder in that the housing has two housing parts which are connected to a web that is massively thickened between these housing parts above the faceplate screw bore. Double locking cylinders with two housing parts, which are connected to a web, are known per se. In the case of these, however, the web between the housing parts was previously designed such that the passage of the driving cam of the locking beard between the housing parts is not hindered. In order to reinforce the web in the area of the faceplate screw hole, it has already been proposed to insert a steel cable into the web. Due to the flexibility of the steel cable, it is hardly possible to tear the web in this version. In the double lock cylinder according to the invention, the web between the housing parts is above the Forend screw massively thickened. Since in the double lock cylinder according to the invention the driver does not pass between the housing parts, the thickening of the steel web is so massive that the weakening by the faceplate screw hole is largely compensated for. This means that the bar can no longer be moved in the area of the faceplate screw hole and therefore no material fatigue is to be expected even after a long bending test. Due to the much more massive thickening of the web, the contact surface of the housing parts on the thickening is also larger and the mobility of the individual parts is further reduced. The housing thus forms a more compact and also much more stable unit. It is not possible to tear the double locking cylinder according to the invention with a drawing tool.

Der Steg ist vorzugsweise aus geschmiedetem Stahl hergestellt. Die Gehäuseteile können durch diesen einbruchsicheren Steg in verschiedenen, auch kostengünstigen Materialien ausgeführt werden. Beispielsweise aus Messing, Zinkdruckguss, Chromnickelstahl oder gehärtetem vergütetem Stahl. Dies ermöglicht bei gleichem Systemaufbau die Herstellung verschiedener Preisklassen vom kostengünstigen Zinkdruckguss-Doppelzylinder bis zum hochwertigen Stahlzylinder. Der für die Sicherheit qualitativ hochwertige Steg gewährleistet die erforderliche Sicherheit. Die Flexibilität des Baukasten-Systems, d.h. die Zylinder können im Laden oder auf der Baustelle auf jede gewünschte Länge individuell verlängert oder verkürzt werden, bleibt voll erhalten. Eine besonders kostengünstige Herstellung ist dann möglich, wenn der Steg gemäss einer weiteren Bildung der Erfindung aus mehreren aneinander gelegten und fest miteinander verbundenen Platten besteht.The web is preferably made of forged steel. The housing parts can be made in various, also inexpensive materials through this burglar-proof web. For example made of brass, die-cast zinc, chrome nickel steel or hardened tempered steel. With the same system structure, this enables the production of different price ranges from the inexpensive zinc die-cast double cylinder to the high-quality steel cylinder. The high quality bridge for safety ensures the necessary safety. The flexibility of the modular system, ie the cylinders can be individually extended or shortened to any desired length in the shop or on the construction site, remains fully intact. A Particularly cost-effective production is possible if, according to a further embodiment of the invention, the web consists of a plurality of plates which are placed against one another and are firmly connected to one another.

Die Erfindung betrifft ebenfalls einen Schliesszylinder mit einem Einsteckschloss, in das der erfindungsgemässe Schliesszylinder eingesetzt ist. Die Erfindung betrifft ebenfalls ein Einsteckschloss mit entsprechendem Zylinderausschnitt, in das der erfindungsgemässe Schliesszylinder eingesetzt wird. Der Schlosskasten besitzt eine Ausnehmung für den Durchtritt des Schliessbartes, die versetzt von der Nullstellung, Abzugstellung des Schlüssels angeordnet ist. Durch diese Konstruktion kann der Zylinder nur mit dem entsprechenden Schlüssel aus dem Schloss entfernt werden, was sicherheitstechnisch sehr wichtig ist. Bei geschlossenem Schloss steht der Schliessbart auf der Verschluss-Seite und steht innenseitig am Gehäuse, an der Schlosskastenwand an und verhindert damit wirksam ein Herausreissen des Schliesszylinders aus dem Schlosskasten.The invention also relates to a locking cylinder with a mortise lock in which the locking cylinder according to the invention is inserted. The invention also relates to a mortise lock with a corresponding cylinder cutout, into which the lock cylinder according to the invention is inserted. The lock case has a recess for the passage of the lock beard, which is arranged offset from the zero position, withdrawal position of the key. This construction means that the cylinder can only be removed from the lock with the appropriate key, which is very important from a safety point of view. When the lock is closed, the lock beard is on the lock side and is on the inside of the housing, on the lock case wall, thus effectively preventing the lock cylinder from being torn out of the lock case.

Der Zylinder gemäss den Figuren 1 und 2 weist zwei gleiche Gehäuseteile 2 auf, die mit einem Steg 18 miteinander fest verbunden sind. Der Steg 18 besitzt zwei Arme 19, die jeweils in eine Ausnehmung 21 eines Zylindersacks 20 eingreifen. Die Gehäuseteile 2 bestehen beispielsweise aus mehreren aneinandergereihten Platten 22. In jedem Gehäuseteil 2 ist ein Zylinderkern 16 gelagert, der einen Schlüsselkanal 17 sowie hier nicht gezeigte Zuhaltungen aufweist. Die beiden Zylinderkerne 16 und ein Schliessbart 6 sind mit einer Kupplung 7 verbunden, die einen toten Drehwinkel von etwa 90° aufweist. Eine solche Kupplung ist aus der CH-A-519 645 bekannt. Wie Figur 2 zeigt, weist die Kupplung 7 eine kreissementförmige Mitnehmerscheibe 11 auf, die eine Sehnenfläche 11A besitzt. Diese Fläche 11A wirkt mit Anschlagflächen 14 und 15 des Schliessbartes 6 derart zusammen, dass bei einer Drehung der Mitnehmerscheibe 11 um 360° der Schliessbart nur um etwa 270° verdreht wird. Die Übertragung der Drehbewegung der Zylinderkerne 16 auf die Mitnehmerscheibe 11 erfolgte über eine zweiteilige Kupplungslatte 9. Diese Platte 9 ist in einen Schlitz 13 der Mitnehmerscheibe 11 eingesetzt. Ein Stift 10 verbindet die Teile der Kupplungsplatte 9 miteinander. Die Figur 2 zeigt die beiden Endpositionen des Mitnehmernockens 6A, einmal mit ausgezogenen Linien und das andere Mal mit gestrichelter Linie.The cylinder according to FIGS. 1 and 2 has two identical housing parts 2 which are firmly connected to one another by a web 18. The web 18 has two arms 19, which each engage in a recess 21 of a cylinder bag 20. The housing parts 2 consist, for example, of several plates 22 lined up in a row. A cylinder core 16 is mounted in each housing part 2 and has a key channel 17 and tumblers, not shown here. The two cylinder cores 16 and a locking beard 6 are connected to a clutch 7, which has a blind rotation angle of approximately 90 °. Such a coupling is known from CH-A-519 645. As FIG. 2 shows, the coupling 7 has a circular disk-shaped drive plate 11, which has a chord surface 11A. This surface 11A interacts with stop surfaces 14 and 15 of the locking beard 6 in such a way that when the driving disk 11 is rotated through 360 °, the locking beard is only rotated by approximately 270 °. The transmission of the rotary movement of the cylinder cores 16 to the drive plate 11 was carried out via a two-part clutch plate 9. This plate 9 is inserted into a slot 13 of the drive plate 11. A pin 10 connects the parts of the clutch plate 9 together. FIG. 2 shows the two end positions of the driver cam 6A, one with solid lines and the other time with a broken line.

Wie die Figur 3A zeigt, ist der Steg 18 im Bereich und über der Stulpschraubenbohrung 4 massiv verdickt. Die Verdickung 3 füllt im wesentlichen den gesamten Zwischenraum zwischen den beiden Zylindersäcken 20 aus. Die Vedickung 3 erstreckt sich nach oben im wesentlichen bis zum Umfang 6B des Schliessbartes 6. Diese Verdickung 3 ist möglich, weil der Mitnehemernocken 6A bei einer Betätigung des Zylinders lediglich um etwa 270° gedreht wird. Der Drehwinkel kann jedoch auch kleiner sein, beispielsweise 180°, was bei einem selbstverriegelnden Schloss besonders vorteilhaft ist. Die Verbindung des Steges 18 mit den Gehäuseteilen 2 erfolgt beispielsweise mit hier nicht gezeigten, an sich gut bekannten Querstiften. Bei der Ausführung gemäss den Figuren 3A und 3B weisen die Arme 19 einen viereckigen Querschnitt auf. Die Ausnehmungen 21 sind korrespondierend dazu ausgebildet.As FIG. 3A shows, the web 18 is massively thickened in the area and above the forend screw bore 4. The thickening 3 essentially fills the entire space between the two cylinder bags 20. The thickening 3 extends essentially up to the circumference 6B of the closing beard 6. This thickening 3 is possible because the driving cam 6A is only rotated by approximately 270 ° when the cylinder is actuated. However, the angle of rotation can also be smaller, for example 180 °, which is particularly advantageous in the case of a self-locking lock. The connection of the web 18 to the housing parts 2 takes place, for example, using cross pins, which are not shown here and are known per se. In the embodiment according to FIGS. 3A and 3B, the arms 19 have a square cross section on. The recesses 21 are designed to correspond.

Bei der Ausführung gemäss den Figuren 4A und 4B ist ein Steg 23 ebenfalls mit einer massiven Verdickung 24 versehen. Die Arme 25 sind im Querschnitt kreisförmig und in korrespondierende Ausnehmungen 27 der Zylinderhälften 2 eingesetzt und ebenfalls mit hier nicht gezeigten Stiften verankert. An dem Gehäuseteil 2 ist bei dieser Ausführung ein Verlängerungsstück 26 angesetzt, welches das gleiche Profil wie der Gehäuseteil 2 aufweist und ebenfalls mit einer Ausnehmung 27 im Zylindersack versehen ist. Das Verlängerungsstück 26 befindet sich beim zusammengebauten Schliesszylinder zwischen der Innenseite 5 des Gehäuseteils 2 und der Verdickung 24 sowie der Kupplung 7. Ein solches Verlängerungsstück 26 kann am Montageort zur Verlängerung des Schliesszylinders 1 eingesetzt werden. Entsprechend dazu wird ein längerer Steg 23 gewählt. Zur geeigneten Verlängerung sind Verlängerungsstücke mit unterschiedlichen Längen, beispielsweise 5 und 10 mm vorgesehen. Stehen ein Satz solcher Verlängerungsstücke 26 sowie unterschiedlich lange Stege 23 zur Verfügung, so wird die Lagerhaltung wesentlich vereinfacht, da die Gehäuseteile 2 dann alle gleich lang sein können. Eine Anpassung der Länge des Schliesszylinders 1 an die örtliche Gegebenheit ist dann jederzeit in einfacher Weise möglich. Auch bei einem solchen zusammengesetzten Gehäuseteil 2A bleibt die hohe Aufbrechsicherheit gewährleistet, da diese bei einem Abbrechversuch vor allem durch den Steg 23 gewährleistet ist.In the embodiment according to FIGS. 4A and 4B, a web 23 is also provided with a massive thickening 24. The arms 25 are circular in cross section and are inserted in corresponding recesses 27 in the cylinder halves 2 and are also anchored with pins, not shown here. In this embodiment, an extension piece 26 is attached to the housing part 2, which has the same profile as the housing part 2 and is also provided with a recess 27 in the cylinder bag. The extension piece 26 is located in the assembled lock cylinder between the inside 5 of the housing part 2 and the thickening 24 and the coupling 7. Such an extension piece 26 can be used at the installation site to extend the lock cylinder 1. Accordingly, a longer web 23 is selected. Extension pieces with different lengths, for example 5 and 10 mm, are provided for suitable extension. If a set of such extension pieces 26 as well as webs 23 of different lengths are available, the storage is considerably simplified since the housing parts 2 can then all be of the same length. An adaptation of the length of the lock cylinder 1 to the local conditions is then possible at any time in a simple manner. Even in the case of such a composite housing part 2A, the high security against tampering is ensured, since this is ensured in particular by the web 23 when attempting to break off.

Die Figuren 5A und 5B zeigen eine weitere Ausführung eines Steges 28 mit einer massiven Verdickung 29 sowie ein Gehäuseteil 31, der für den Steg 28 eine unten offene Ausnehmung 30 besitzt. Der Steg 28 ist vorzugsweise geschmiedet und besteht aus vergütetem Stahl.FIGS. 5A and 5B show a further embodiment of a web 28 with a massive thickening 29 and a housing part 31 which has a recess 30 open at the bottom for the web 28. The web 28 is preferably forged and made of tempered steel.

Schliesslich zeigen die Figuren 6A bis 6C einen Steg 32, der aus mehreren gleichen, aneinandergelegten Platten 33 aus vergütetem Stahl besteht. Ein solcher Steg 32 ist in besonders kostengünstiger Weise aus gestanzten Latten 33 herstellbar.Finally, FIGS. 6A to 6C show a web 32 which consists of several identical plates 33 made of tempered steel which are placed one against the other. Such a web 32 can be produced from punched slats 33 in a particularly cost-effective manner.

Die Figur 7 zeigt ein an sich bekanntes Einsteckschloss 35 mit einem Zylinderausschnitt 36 im Schlosskasten 37, in den der erfindungsgemässe Schliesszylinder 1 bei der Montage eingesetzt wird. Der Schlosskasten 37 besitzt zudem eine Ausnehmung 38 für den Durchtritt des Schliessbartes 6, welche versetzt von der Nullstellung, Abzugstellung des Schlüssels angeordnet ist. Dadurch kann der montierte Schliesszylinder 1 nur mit dem zugehörigen Schlüssel aus dem Einsteckschloss 35 entfernt werden, was sicherheitstechnisch sehr wichtig ist. Bei geschlossenem Schloss steht der Schliessbart 6 auf der Verschluss-Seite und damit ausserhalb der Ausnehmung 38 innenseitig Schlosskasten 37 an und verhindert damit wirksam ein Herausreissen des Schliesszylinders 1 aus dem Schlosskasten 37.FIG. 7 shows a mortise lock 35 known per se with a cylinder cutout 36 in the lock case 37, into which the lock cylinder 1 according to the invention is inserted during assembly. The lock case 37 also has a recess 38 for the passage of the lock beard 6, which is arranged offset from the zero position, withdrawal position of the key. As a result, the assembled lock cylinder 1 can only be removed from the mortise lock 35 with the associated key, which is very important in terms of security. When the lock is closed, the lock beard 6 is on the lock side and thus outside the recess 38 on the inside lock case 37 and thus effectively prevents the lock cylinder 1 from being torn out of the lock case 37.
