Abstract

A cutout (11) is made in a web (7) from above, a locking element (12) being inserted into said cutout. The cutout (11) connects an upper outer side of the web (7) to a transverse bore (9) in an arm (14) of the web (7). In the assembled state, the web (7) is inserted into a cutout (10) of the cylinder pocket (4) and connected by a transverse pin (6). In order to secure the transverse pin (6) against longitudinal displacement in the cylinder pocket (4), said transverse pin (6) exhibits an encircling groove (14) into which the locking element (12) engages from above. In order to exchange the web (7), the rotary cylinder (1) is rotated about its longitudinal axis such that the cylinder pocket (4) is at the top. Upon rotation, the locking element (12) moves downwards due to its gravitational force and releases the transverse pin (6). The rotary cylinder (1) according to the invention can be lengthened or shortened on site, without reducing the security, by exchanging the web (7). <IMAGE>

Description

Die Erfindung betrifft einen Drehschliesszylinder für ein Sicherheitsschloss, mit einem Zylindergehäuse und einem in eine Ausnehmung des Zylindergehäuses eingesetzten und mit einem Querstift gesicherten Steg.The invention relates to a rotary lock cylinder for a security lock, with a cylinder housing and a web inserted into a recess in the cylinder housing and secured with a cross pin.

Drehschliesszylinder dieser Art sind gut bekannt. Bei einem Doppeldrehschliesszylinder verbindet der Verbindungssteg zwei gleiche Drehschliesszylinder. Ein Schloss kann dann von beiden Türseiten her bedient werden. Doppeldrehschliesszylinder mit einem Verbindungssteg haben insbesondere den Vorteil, dass diese auf der Baustelle verlängert oder verkürzt werden können. Dazu wird der Steg durch einen solchen mit einer entsprechend anderen Länge ersetzt. Dies bedingt jedoch, dass die Verbindung zwischen dem Verbindungssteg und den Drehschliesszylindern auf einfache Weise gelöst werden kann. Aus Sicherheitsgründen sollte diese Verbindung beim montierten Drehschliesszylinder jedoch von aussen nicht lösbar sein.Rotary lock cylinders of this type are well known. In the case of a double rotary lock cylinder, the connecting web connects two identical rotary lock cylinders. A lock can then be operated from both sides of the door. Double rotary lock cylinders with a connecting web have the particular advantage that they extend on the construction site or can be shortened. For this, the web is replaced by one with a correspondingly different length. However, this means that the connection between the connecting web and the rotary lock cylinders can be released in a simple manner. For security reasons, this connection should not be detachable from the outside when the rotary lock cylinder is installed.

Der Erfindung liegt die Aufgabe zugrunde, einen Drehschliesszylinder und insbesondere einen Doppeldrehschliesszylinder derart auszubilden, dass der Verbindungssteg in einfacher Weise ausgewechselt werden kann, beim montierten Drehschliesszylinder die Verbindung zwischen dem Verbindungssteg und dem Zylindergehäuse jedoch nicht lösbar ist.The invention has for its object to design a rotary lock cylinder and in particular a double rotary lock cylinder such that the connecting web can be replaced in a simple manner, but the connection between the connecting web and the cylinder housing is not detachable when the rotary lock cylinder is installed.

Die Aufgabe ist beim erfindungsgemässen Drehschliesszylinder dadurch gelöst, dass ein Verriegelungselement über dem Querstift verschiebbar in einer Ausnehmung des Steges angeordnet ist und dieses Verriegelungselement in eine Ausnehmung des Querstiftes eingreift um diesen gegen eine Längsverschiebung zu sichern. Um einen Verlängerungssteg gegen einen anderen auszuwechseln, wird der Drehschliesszylinder um seine Längsachse so gedreht, dass der Zylindersack oben ist. Das Verriegelungselement fällt, gegebenenfalls nach leichtem Schütteln, in der Ausnehmung des Steges etwas nach unten, so dass der Eingriff des Verriegelungselementes am Querstift aufgehoben wird. Der gelöste Querstift kann nun entfernt und der Verlängerungssteg aus dem Zylinder herausgezogen werden. Beim Drehen des Drehschliesszylinders in die übliche Lage fällt das Verriegelungselement wieder nach unten und greift in die Ausnehmung des Querstiftes ein, so dass dieser gegen ein Verschieben gesichert ist. Ein nochmaliges Auswechseln des Verlängerungssteges ist auf die gleiche Weise ohne weiteres möglich. Der erfindungsgemässe Drehschliesszylinder eignet sich deshalb vorzüglich für ein Baukastensystem, bei dem auf der Baustelle der Schliesszylinder verlängert oder verkürzt werden kann. Da ein montierter Drehschliesszylinder üblicherweise nicht gedreht werden kann, ist es auch nicht möglich, die Verbindung zwischen dem Verlängerungssteg und dem Drehschliesszylinder zu lösen.The object is achieved in the rotary lock cylinder according to the invention in that a locking element is arranged displaceably over the cross pin in a recess of the web and this locking element engages in a recess of the cross pin in order to secure it against longitudinal displacement. In order to exchange one extension web for another, the rotary lock cylinder is turned around its longitudinal axis so that the cylinder bag is on top. The locking element falls, possibly after shaking gently, somewhat downwards in the recess of the web, so that the locking element engages on Cross pin is lifted. The loosened cross pin can now be removed and the extension web pulled out of the cylinder. When the rotary lock cylinder is turned into the usual position, the locking element falls down again and engages in the recess in the cross pin, so that it is secured against displacement. A renewed replacement of the extension bar is easily possible in the same way. The rotary lock cylinder according to the invention is therefore particularly suitable for a modular system in which the lock cylinder can be extended or shortened on the construction site. Since an assembled rotary lock cylinder usually cannot be turned, it is also not possible to release the connection between the extension web and the rotary lock cylinder.

Weitere vorteilhafte Merkmale ergeben sich aus den abhängigen Ansprüchen, der Beschreibung und der Zeichnung.Further advantageous features result from the dependent claims, the description and the drawing.

Ein Ausführungsbeispiel des erfindungsgemässen Drehschliesszylinders wird nachfolgend anhand der Zeichnung näher erläutert. Es zeigen:

Fig. 1
ein erfindungsgemässer Drehschliesszylinder, wobei einzelne Teile aus Darstellungsgründen auseinander gezogen sind,
Fig. 2
einen Teilschnitt durch einen erfindungsgemässen Drehschliesszylinder, und
Fig. 3
ein Schnitt entsprechend Fig. 2, jedoch bei einem umgedrehten Drehschliesszylinder.
An embodiment of the rotary lock cylinder according to the invention is explained in more detail below with reference to the drawing. Show it:
Fig. 1
a rotary lock cylinder according to the invention, individual parts being pulled apart for reasons of illustration,
Fig. 2
a partial section through a rotary lock cylinder according to the invention, and
Fig. 3
a section corresponding to FIG. 2, but with an inverted rotary lock cylinder.

Die Fig. 1 zeigt einen Drehschliesszylinder 1, einen vorzugsweise aus abbruchfestem Chromnickelstahl hergestellten Verbindungssteg 7 sowie einen Querstift 6, mit dem der Steg 7 im Drehschliesszylinder 1 gesichert ist. Der Drehschliesszylinder 1 weist ein an sich bekanntes Zylindergehäuse 13 mit einem Zylindersack 4 sowie einer Querbohrung 5 für den Stift 6 auf. Im Zylindergehäuse 13 ist ein üblicher Rotor 2 mit einem Schlüsselkanal 3 gelagert. Im Drehschliesszylinder 1 sind übliche Zuhaltungen untergebracht, die mit einem zugehörigen Schlüssel eingeordnet werden können.1 shows a rotary lock cylinder 1, a connecting web 7, preferably made of demolition-resistant chromium-nickel steel, and a cross pin 6, with which the web 7 is secured in the rotary lock cylinder 1. The rotary lock cylinder 1 has a cylinder housing 13 known per se with a cylinder bag 4 and a transverse bore 5 for the pin 6. A conventional rotor 2 with a key channel 3 is mounted in the cylinder housing 13. Conventional tumblers are accommodated in the rotary lock cylinder 1, which can be classified with an associated key.

Der Steg 7 weist zwei Arme 14 auf, die unterschiedlich lang sein können und in die jeweils eine Querbohrung 9 für die Aufnahme eines Querstiftes 6 eingearbeitet ist. Zwischen den Armen 14 ist eine übliche Gewindebohrung 8 für die Aufnahme einer hier nicht gezeigten Stulpschraube angeordnet. Bei einem Doppelschliesszylinder sind die Arme 14 jeweils in eine entsprechende, auf der Rückseite des Gehäuses 13 offene Ausnehmung 10 eines Drehschliesszylinders 1 eingesetzt.The web 7 has two arms 14, which can be of different lengths and in each of which a transverse bore 9 is incorporated for receiving a cross pin 6. Between the arms 14, a conventional threaded bore 8 is arranged for receiving a forend screw, not shown here. In the case of a double lock cylinder, the arms 14 are each inserted into a corresponding recess 10 of a rotary lock cylinder 1 which is open on the rear side of the housing 13.

Im montierten Zustand ist der Verbindungssteg 7 gemäss Fig. 2 fest mit den beiden Drehschliesszylindern 1 verbunden. Wie ersichtlich, geht der Querstift 6 durch die Bohrung 5 des Zylindergehäuses 13 und durch eine Bohrung 9 des Steges 7 hindurch. Ein Verriegelungselement 12, das ein einfacher zylindrischer Stift sein kann, ist in eine Bohrung 11 des Steges 7 eingesetzt und greift mit seinem unteren Ende in eine umlaufende Nut 14 des Querstiftes 6 ein. Das Verriegelungselement 12 verhindert somit ein Verschieben des Querstiftes 6 im Zylindersack 4 und damit ein Lösen des Verbindungssteges 7 vom Zylindergehäuse 13. Ist der Drehschliesszylinder 1 mit dem montierten Verbindungssteg 7 in einer hier nicht gezeigten Tür eingebaut, so ist der Zylindersack 4, wie in Fig. 1 gezeigt, unten und das Verriegelungselement 12 ist gemäss Fig. 2 in Eingriff mit dem Querstift 6. Wird der Drehschliesszylinder 1 vor dem Einsetzen in eine Türe mit dem Verbindungssteg 7 so um seine Längsachse gedreht, dass der Zylindersack 4 gemäss Fig. 3 oben ist, so bewegt sich das Verriegelungselement 12 infolge seiner Schwerkraft in der Ausnehmung oder Bohrung 11 nach unten in die in Fig. 3 gezeigte Lage. Wie ersichtlich ist in dieser Lage das Verriegelungselement nicht in Eingriff mit dem Querstift 6. In dieser Lage des Drehschliesszylinders 1 kann somit der Querstift 6 in seiner Längsrichtung im Zylindersack 4 verschoben und damit die Verbindung zwischen dem Verbindungssteg 7 und dem Zylindergehäuse 13 gelöst werden. Das Verriegelungselement 12 bleibt beim Umdrehen des Drehschliesszylinders 1 in der Ausnehmung 11 und kann nicht verlorengehen.In the assembled state, the connecting web 7 according to FIG. 2 is firmly connected to the two rotary lock cylinders 1. As can be seen, the cross pin 6 passes through the bore 5 of the cylinder housing 13 and through a bore 9 of the web 7. A locking element 12, which can be a simple cylindrical pin, is inserted into a bore 11 of the web 7 and engages with its lower end in a circumferential groove 14 of the cross pin 6. The locking element 12 thus prevents displacement of the cross pin 6 in the cylinder bag 4 and thus detachment of the connecting web 7 from the cylinder housing 13. If the rotary lock cylinder 1 with the mounted connecting web 7 is installed in a door (not shown here), the cylinder bag 4, as shown in 1, below and the locking element 12 is in accordance with FIG. 2 in engagement with the transverse pin 6. If the rotary lock cylinder 1 is rotated about its longitudinal axis with the connecting web 7 before being inserted into a door such that the cylinder bag 4 in accordance with FIG. 3 is at the top is, the locking element 12 moves due to its gravity in the recess or bore 11 down into the position shown in Fig. 3. As can be seen in this position, the locking element is not in engagement with the cross pin 6. In this position of the rotary lock cylinder 1, the cross pin 6 can thus be displaced in its longitudinal direction in the cylinder bag 4 and thus the connection between the connecting web 7 and the cylinder housing 13 can be solved. The locking element 12 remains in the recess 11 when the rotary lock cylinder 1 is turned over and cannot be lost.

Der gelöste Verbindungssteg 7 kann nun durch einen anderen Verbindungssteg ausgetauscht und durch Einsetzen des Querstiftes 6 im Drehschliesszylinder 1 verriegelt werden. Wird der Drehschliesszylinder 1 mit dem neuen Verbindungssteg wieder in die in Fig. 2 gezeigte übliche Lage gedreht, so fällt das Verriegelungselement 12 durch seine Schwerkraft von selbst in die verriegelnde, in Fig. 2 gezeigte Lage. Nach dem Einbau des Drehschliesszylinders in eine Tür ist das Verriegelungselement 12 von aussen nicht zugänglich und kann auch sonst nicht in eine freigebende Position bewegt werden.The released connecting web 7 can now be replaced by another connecting web and locked in the rotary lock cylinder 1 by inserting the cross pin 6. If the rotary lock cylinder 1 is rotated again with the new connecting web into the usual position shown in FIG. 2, the locking element 12 automatically falls into the locking position shown in FIG. 2 due to its gravity. After the rotary lock cylinder has been installed in a door, the locking element 12 is not accessible from the outside and cannot be moved to a releasing position.

In der Regel verbindet der Steg 7 zwei gleiche Drehschliesszylinder 1, es sind jedoch auch Ausführungen denkbar, bei denen der Steg 7 unterschiedliche Drehschliesszylinder verbindet. Schliesslich ist es auch möglich, dass lediglich ein Drehschliesszylinder 1 mit einem Steg 7 verbunden ist.As a rule, the web 7 connects two identical rotary lock cylinders 1, but designs are also conceivable in which the web 7 connects different rotary lock cylinders. Finally, it is also possible for only one rotary lock cylinder 1 to be connected to a web 7.
