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 nach dem Oberbegriff des Anspruchs 1.The invention relates to a built-in double lock cylinder for a security lock according to the preamble of the claim 1.

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 Messingdoppelschliesszylinder 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 is from CH-A-519 645 became known. The case is made of one Piece manufactured and in the area of the faceplate screw hole reinforced. Because with this locking cylinder in the housing Not recess for the driver cam of the locking beard the cross-sectional area of the housing is required much less at the location of the faceplate screw hole weakened than before. So it's for a burglar more difficult, with a suitable tool a protruding Clamp the end of the double locking cylinder and the cylinder housing on the weakened through the faceplate screw hole Place to break. Enough for the burglar Such a brass double locking cylinder can be available due to material fatigue the weak point mentioned easily broken and that Lock to be opened. Drawing tools are also offered, with which double cylinders made of brass were torn apart can be.

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 a built-in double lock cylinder to create the aforementioned genus where it is even more difficult, the blocking organs to overcome the locking cylinder by force with aids.

Die Aufgabe ist bei einem gattungsgemässen Doppelschliesszylinder gemäss Anspruch 1 gelöst. 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 task is with a generic double lock cylinder solved according to claim 1. Double locking cylinder with two housing parts, with a web connected are known per se. But with these was so far the web between the housing parts was designed that the passage of the driver cam of the beard between the housing parts is not hindered. Around the jetty is to be reinforced in the area of the faceplate screw hole have already been proposed to insert a steel cable in the web. Due to the flexibility of the steel cable it is hardly possible to tear the bridge with this version. In the double lock cylinder according to the invention, the web is between the housing parts above the Forend screw massively thickened. Since in the inventive Double locking cylinder of the driver between the housing parts does not pass through, is the thickening of the Steel web so solid that the weakening by the faceplate screw hole is largely balanced. The The bar cannot be in the area of the faceplate screw hole be moved more and that's why it's also a long one ongoing fatigue testing no material fatigue to be expected. Due to the much more massive thickening of the web is also the contact surface of the housing parts on the thickening greater and thus the mobility of the individual Parts further reduced. The housing thus forms one more compact and also much more stable unit. A tear of the double lock cylinder according to the invention a pulling tool is not possible.

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 burglar-proof Bridge in various, also inexpensive materials be carried out. For example made of brass, die-cast zinc, Chromium nickel steel or hardened tempered steel. This enables production with the same system structure different price ranges from the inexpensive zinc die-cast double cylinder to high quality steel cylinders. The for the safety high quality bridge is guaranteed the necessary security. The flexibility of the Modular system, i.e. the cylinders can be in the store or individually on the construction site to any desired length lengthened or shortened remains fully intact. A Particularly inexpensive manufacture is possible if the web according to a further embodiment of the invention several connected and firmly connected Plates exists.

Die Erfindung betrifft ebenfalls einen Schliesszylinder mit einem Einsteckschloss, in das der erfindungsgemässe Schliesszylinder eingesetzt ist. 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 a mortise lock, in which the inventive Lock cylinder is used. The lock case has a recess for the passage of the mustache, which is offset by the Zero position, withdrawal position of the key is arranged. Due to this construction, the cylinder can only be used with the appropriate Keys are removed from the lock what is very important in terms of safety. When closed The lock has the beard on the lock side and is on the inside of the housing, on the lock case wall and thus effectively prevents the Lock cylinder from the lock case.

Figur 7 eine Teilansicht eines Schlosskastens mit einem Zylinderausschnitt.Figure 7 is a partial view of a lock case with a cylinder cutout.

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 Figures 1 and 2 has two of the same Housing parts 2, which are fixed to each other with a web 18 are connected. The web 18 has two arms 19, each engage in a recess 21 of a cylinder bag 20. The housing parts 2 consist, for example, of several lined-up panels 22. In each housing part 2 a cylinder core 16 is mounted, which is a key channel 17 and tumblers not shown here. The two Cylinder cores 16 and a locking beard 6 are with a Coupling 7 connected, the dead angle of rotation of about 90 °. Such a coupling is from CH-A-519 645 known. As Figure 2 shows, the coupling 7 has a circular element Driving plate 11 on a tendon surface 11A. This surface 11A acts with stop surfaces 14 and 15 of the mustache 6 together such that at a rotation of the driving plate 11 by 360 ° of the closing beard is only rotated by about 270 °. The transfer of the Rotary movement of the cylinder cores 16 on the drive plate 11 was carried out via a two-part coupling batten 9. This Plate 9 is in a slot 13 of the drive plate 11 used. A pin 10 connects the parts of the clutch plate 9 with each other. Figure 2 shows the two end positions of the driving cam 6A, once 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 in the area and over the faceplate screw hole 4 massively thickened. The thickening 3 essentially fills the entire space between the two cylinder bags 20. The thickening 3 extends upwards essentially to the extent 6B of the Lock beard 6. This thickening 3 is possible because of the Mitnehemernocken 6A only when the cylinder is actuated is rotated by about 270 °. However, the angle of rotation can also be smaller, for example 180 °, which is one self-locking lock is particularly advantageous. The The web 18 is connected to the housing parts 2 for example with well-known ones not shown here Cross pins. When executed according to the figures 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 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 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. 4A and 4B is a Web 23 also provided with a massive thickening 24. The arms 25 are circular in cross section and in corresponding recesses 27 of the cylinder halves 2 used and also with pins not shown here anchored. On the housing part 2 is in this version an extension piece 26 attached, which is the same Profile as the housing part 2 and also with a Recess 27 is provided in the cylinder bag. The extension piece 26 is in the assembled Lock cylinder between the inside 5 of the housing part 2 and the and the thickening 24 and the clutch 7. Such Extension piece 26 can be extended at the installation site of the lock cylinder 1 are used. Accordingly a longer web 23 is selected. For a suitable extension are extension pieces with different Lengths, for example 5 and 10 mm are provided. Stand on Set of such extension pieces 26 and different Long webs 23 are available, so storage becomes essential simplified, since the housing parts 2 then all can be the same length. An adjustment of the length of the Lock cylinder 1 to the local situation is then possible at any time in a simple manner. Even with one Composite housing part 2A remains the high security against break-open guaranteed as this when trying to cancel is ensured above all by the web 23.

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, a recess open below for the web 28 30 owns. The web 28 is preferably forged and consists 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, that of several identical plates 33 placed one against the other made of tempered steel. Such a web 32 is in made of punched slats 33 in a particularly cost-effective manner producible.

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, in the the lock cylinder 1 according to the invention during assembly is used. The lock case 37 also has one Recess 38 for the passage of the mustache 6, which offset from the zero position, deduction position of the Key is arranged. This allows the assembled Lock cylinder 1 only with the associated key the mortise lock 35 are removed, which is safety-related is very important. When the lock is closed the locking beard 6 on the locking side and thus outside the recess 38 on the inside lock case 37 and thus effectively prevents the Lock cylinder 1 from the lock case 37.
