Die Erfindung betrifft eine Befestigung für den Sperrbügel am Schließkasten eines Kastenschlosses, wobei dieser mittels einer Schraube schwenkbar am-Schließkasten angebracht ist und mit einem Riegel am Türblatt bzw. Türrahmen zusammenwirkt.The invention relates to a fastening for the locking bracket on the lock case of a box lock, whereby the locking bracket is pivotably attached to the lock case by means of a screw and interacts with a bolt on the door leaf or door frame.
Mit dem am Schloßkasten befestigten Sperrbügel, der mit dem Riegel zusammenwirkt, wird erreicht, dass eine Tür nur einen spaltbreit geöffnet werden kann. Damit wird eine Sicherheit gegen ein unerlaubtes Eindringen, trotz geöffneter Tür, geboten. Andererseits kann eine derartig, spaltbreit geöffnete Tür, mit bestimmten Werkzeugen, wie Maulschlüssel, Schraubendrehen und dgl. dann geöffnet werden, wenn mit diesen Werkzeugen die den Sperrbügel am Schließkasten haltende Schraube, durch den Öffnungsspalt hindurch, entfernt wird.The locking bar attached to the lock case, which works together with the bolt, ensures that a door can only be opened a crack. This provides security against unauthorized entry, even when the door is open. On the other hand, a door that is opened a crack like this can be opened with certain tools, such as open-end wrenches, screwdrivers, etc., if the screw holding the locking bar to the lock case is removed through the opening gap using these tools.
Der Erfindung liegt die Aufgabe zugrunde, den Sperrbügel am Schließkasten so zu befestigen, dass die Tür bei verriegeltem Sperrbügel - auch wenn sie spaltbreit geöffnet ist - nicht weiter geöffnet werden kann bzw. nur mit einem sehr hohen werkzeugtechnischem Aufwand.The invention is based on the object of attaching the locking bar to the lock box in such a way that the door cannot be opened any further when the locking bar is locked - even if it is opened a crack - or can only be opened with a very high level of tooling effort.
Gelöst wird diese Aufgabe erfindungsgemäß bei einer Befestigung für den Sperrbügel am Schließkasten eines Kastenschlosses, der mittels einer Schraube schwenkbar am Schließkasten angebracht ist und mit einem Riegel am Türblatt bzw. Türrahmen zusammenwirkt, dadurch, dass der Kopf der Schraube ein eine geringe Höhe aufweisender, mit einer umlaufenden Fase versehener Rundkopf ist, an dem eine - in Aufsicht gesehen sekantenartig verlaufende Abflachung vorgesehen ist.This object is achieved according to the invention in a fastening for the locking bracket on the lock case of a box lock, which is pivotably attached to the lock case by means of a screw and interacts with a bolt on the door leaf or door frame, in that the head of the screw is a round head with a low height, a circumferential bevel and a flattening which runs in a secant-like manner when viewed from above.
Durch diese spezielle Ausbildung der den Befestigungsbügel haltenden Schraube, deren Kopf eine geringe Höhe aufweist und nur mit einer Abflachung versehen ist, läßt sich dieser durch die nur spaltbreit geöffnete Tür nicht mit gängigen Werkzeugen erfassen bzw. es können keine ausreichenden Winkelbewegungen mit einem Werkzeug ausgeführt werden, so das ein Entfernen der Schraube nicht mehr möglich ist.Due to the special design of the screw holding the fastening bracket, whose head is low and only has a flattened area, it cannot be grasped with conventional tools through the door which is only opened a crack, or sufficient angular movements cannot be carried out with a tool, so that the screw can no longer be removed.
Die Erfindung soll nachfolgend mit Bezug auf die Zeichnungen erläutert werden, wobei in derThe invention will be explained below with reference to the drawings, in which
Fig. 1 die bisherige und die erfindungsgemäße Anordnung und Ausbildung der Schraube zum Halten des BefestigungsbügelsFig. 1 the previous and the inventive arrangement and design of the screw for holding the fastening bracket
und inand in
Fig. 2 die bisherige und erfindungsgemäße Ausbildung der Schraube dargestellt sind.Fig. 2 shows the previous and inventive design of the screw.
In der Figur 1 ist lediglich der Schließkasten eines üblichen Kastenschlosses angedeutet. Dieser ist mit 5 bezeichnet. An dem Schließkasten ist der Sperrbügel 6 mittels einer Schraube 1 schwenkbar befestigt, und zwar derart, dass er in der Schwenkstellung mit dem Riegel 7 zusammenwirken kann.In Figure 1, only the lock box of a conventional box lock is indicated. This is designated 5. The locking bracket 6 is pivotably attached to the lock box by means of a screw 1 in such a way that it can interact with the bolt 7 in the pivoted position.
Wie sich aus dieser und der Figur 2 ergibt, weist die Schraube 1 einen Rundkopf 2 geringer Höhe auf, der mit einer umlaufenden Fase 3 versehen ist. Dieser Rundkopf ist mit einer sekantenartig verlaufenden Abflachung 4 versehen, die das Ansetzen eines üblichen Werkzeuges durch eine nur spaltbreit geöffnete Tür verhindert, zumindest aber sehr erschwert.As can be seen from this and Figure 2, the screw 1 has a round head 2 of low height, which is provided with a circumferential bevel 3. This round head is provided with a secant-like flattening 4, which prevents the insertion of a conventional tool through a door that is only slightly open, or at least makes it very difficult.
Die Schraube ist so ausgebildet, dass zwischen deren Kopf und dem Gewindeschaft ein Übergangsteil vorgesehen ist, dessen Durchmesser größer ist als der des Gewindeschaft aber kleiner als der des Kopfes der Schraube.The screw is designed in such a way that a transition part is provided between its head and the threaded shaft, the diameter of which is larger than that of the threaded shaft but smaller than that of the head of the screw.
Um die Auflagefläche zu vergrößern, ist eine Exzentrizität vorgesehen, und zwar ist die Achse des Kopfes der Schraube gegenüber der Achse des Übergangsteiles und des Gewindeschaftes exzentrisch versetzt.In order to increase the contact surface, an eccentricity is provided, namely the axis of the head of the screw is eccentrically offset from the axis of the transition part and the threaded shaft.
