  • a burglar-resistant additional locking device of the aforementioned type is already known, as can be seen, for example, from DE 38 34 373 A1 and DE 38 44 627 A1. It is characterized by the fact that it is largely independent of the espagnolette fittings conventionally installed between the sash and the frame and can therefore be adapted in terms of its structure and mode of operation without problems - and even subsequently - to different needs or different requirements.
  • this known burglar-resistant additional locking is parallel to the connecting rod fitting, but at a different location than this, the wing and the frame associated with an additional connecting rod fitting with its own actuator, in such a way that the actuator of the additional connecting rod fitting and the actuator of the connecting rod fitting only a common control handle are coupled together.
  • the additional connecting rod fitting has only locking members and locking member abutments, which can be set in mutual support engagement with one another in the closed switch position of the usual connecting rod fitting. If the usual connecting rod fitting is a tilt and turn fitting, some of the locking members can still engage with the associated locking member abutments even in the tilt-open switching position.
  • Up and down locking rods emerge from the housing of the actuating gear placed on the end face of the wing on the room side, which have to be mounted in a visible arrangement on the wing and thereby extend over its entire height.
  • An additional locking device designed in this way affects the appearance of the window, the door or the like considerably because the locking rods protruding from the housing as additional locking bars have to be made relatively bulky if they are to fulfill the intended function of burglar resistance.
  • a disadvantage of the burglar-resistant additional locks according to DE 38 22 343 A1 and according to DE 89 06 629 U1 is, however, that in the event of retrofitting, that is, when already installed windows, doors or the like are to be equipped with an additional lock that matches the existing connecting rod fitting, in particular turn-tilt fitting, assigned operating hand lever with bearing rosette removed and overall must be replaced by the additional lock equipped with its own operating hand lever.
  • a disadvantage of all burglar-resistant additional locks of the type dealt with above is that the engagement and disengagement of the additional bolts relative to the inclusion parts anchored on the face-side end face of the frame is inevitably dependent on the actuation of the operating hand lever which adjusts the connecting rod fitting, in particular a tilt and turn fitting . That is, the additional bolts of the additional locking mechanism are always brought into engagement position with the cover part on the frame side when the shifting of the connecting rod fitting into its closed switch position takes place via the operating hand lever. On the other hand, they are also in the Release position moves as soon as the operating lever of the connecting rod fitting is shifted from its locking switch position.
  • the invention aims to provide a device for burglar-resistant additional locking of the sash of windows, doors or the like with the generic features mentioned at the outset, which enables interaction with the operating hand lever of an espagnolette fitting, in particular a turn-tilt fitting, which is usually seated in a bearing rosette, but at the same time ensures that the additional bolt or bolts can be brought into the engaged position and the disengaged position independently of this operating hand lever.
  • a design of the burglar-resistant additional locking system has proven particularly useful, which, when the additional locking bar is in the engaged position, allows the unhindered switching of the operating lever for the espagnolette fitting into any possible functional position, but which only enables the additional bolt to be moved from its engaged position to the disengaged position after the operating hand lever has been operated beforehand of the espagnolette fitting from its basic switch position - primarily the lock switch position - into the next or subsequent switch position - the rotary opening switch position - and which, when the additional bolt is disengaged, switches the operating lever back into its basic switch position - the lock switch position - blocked, its further movement into the end switch position - in particular the tilt opening switch position - but allows.

Abstract

For sashes (leaves) 3 of windows, doors or the like, which are equipped with a drive-rod fitting 4, in particular a side/bottom sash fitting, which exhibits an actuating gearing with a rotary-drive member which is accommodated in a gearing housing 7 and is intended for the drive rods, the invention proposes the use of a device for supplementary locking 13 which inhibits break-in. Said device has a housing 15 which can be positioned on the room-side end surface of the sash, movably mounts and/or guides at least one supplementary locking bar 18 and can be placed, as a retrofitting and/or supplementing element, beneath the bearing rosette 10 of the operating hand lever 9, and is thereby penetrated by the drive pin 8 of the operating hand lever 9 and also by the anchor screws 11 for the bearing rosette 10 thereof. Provided as adjustment member for the supplementary locking bar 18 is a supplementary handle 20 which is mounted in the housing 15 at a distance from the through-passage region for the drive pin 8 of the operating hand lever 9, and the housing 15 which contains the supplementary locking bar 18 mounts, in the through-passage region for the drive pin 8 of the operating hand lever 9, a cam plate 26 which can be coupled in a rotationally fixed manner to said lever. Said cam plate 26 is provided on its circumference with a plurality of, that is to say at least two, cam surfaces which are offset at an angle of rotation with respect to one another, are delimited in a rectilinear manner at least in certain areas and are arranged at different radial spacings from the axis of rotation of the cam plate. In the housing 15 which contains the supplementary locking bar 18, a slide 38 can be displaced to a limited extent on a plane normal to both the axis of rotation of the cam plate 26 and to the axis of rotation of the operating hand lever 9 and/or rotary-drive pin 8, it being directed towards the movement path of the supplementary handle 20 by its one end and the movement path of the cam plate 26 by its other end. In this arrangement, the slide 38 has a length, by which it alternately blocks, within the housing 15, either the movement path of the cam plate 26 or the movement path of the supplementary handle 20. <IMAGE>

Eine einbruchhemmende Zusatzverriegelung vorgenannter Art ist bereits bekannt, wie beispielsweise aus DE 38 34 373 A1 und DE 38 44 627 A1 hervorgeht. Sie zeichnet sich dadurch aus, daß sie von den herkömmlicherweise zwischen Flügel und Rahmen eingebauten Treibstangenbeschlägen weitestgehend unabhängig ist und sich deshalb in ihrem Aufbau und in ihrer Wirkungsweise problemlos - und zwar sogar nachträglich noch - auf verschiedene Bedürfnisse bzw. an verschiedene Anforderungen anpassen läßt. Bei dieser bekannten einbruchhemmenden Zusatzverriegelung ist parallel zum Treibstangenbeschlag, aber an einer anderen Stelle als dieser, dem Flügel und dem Blendrahmen ein Zusatz-Treibstangenbeschlag mit eigenem Stellgetriebe zugeordnet, und zwar derart, daß das Stellgetriebe des Zusatz-Treibstangenbeschlages und das Stellgetriebe des Treibstangenbeschlages lediglich über einen gemeinsamen Bedienungsgriff miteinander gekuppelt sind. Dabei weist der Zusatz-Treibstangenbeschlag lediglich Riegelglieder sowie Riegelglied-Widerlager auf, die in der Verschluß-Schaltstellung des üblichen Treibstangenbeschlages miteinander in gegenseitigen Stützeingriff stellbar sind. Ist der übliche Treibstangenbeschlag ein Drehkipp-Beschlag, dann kann ein Teil der Riegelglieder mit den zugehörigen Riegelglied-Widerlagern auch noch bei Kippöffnungs-Schaltstellung in Eingriff stehen.A burglar-resistant additional locking device of the aforementioned type is already known, as can be seen, for example, from DE 38 34 373 A1 and DE 38 44 627 A1. It is characterized by the fact that it is largely independent of the espagnolette fittings conventionally installed between the sash and the frame and can therefore be adapted in terms of its structure and mode of operation without problems - and even subsequently - to different needs or different requirements. In this known burglar-resistant additional locking is parallel to the connecting rod fitting, but at a different location than this, the wing and the frame associated with an additional connecting rod fitting with its own actuator, in such a way that the actuator of the additional connecting rod fitting and the actuator of the connecting rod fitting only a common control handle are coupled together. The additional connecting rod fitting has only locking members and locking member abutments, which can be set in mutual support engagement with one another in the closed switch position of the usual connecting rod fitting. If the usual connecting rod fitting is a tilt and turn fitting, some of the locking members can still engage with the associated locking member abutments even in the tilt-open switching position.

Aus dem auf die raumseitige Stirnfläche des Flügels aufgesetzten Gehäuse des Stellgetriebes treten jeweils nach oben und nach unten gerichtete Verschlußstangen aus, die in sichtbarer Anordnung am Flügel montiert werden müssen und sich dabei über dessen Gesamthöhe hinweg erstrecken.Up and down locking rods emerge from the housing of the actuating gear placed on the end face of the wing on the room side, which have to be mounted in a visible arrangement on the wing and thereby extend over its entire height.

Eine solchermaßen ausgelegte Zusatzverriegelung beeinträchtigt die Optik des Fensters, der Tür od. dgl. erheblich, weil die als Zusatzriegel aus dem Gehäuse herausragenden Verschlußstangen verhältnismäßig klobig ausgeführt werden müssen, wenn sie die ihnen zugedachte Aufgabe der Einbruchhemmung ausreichend erfüllen sollen.An additional locking device designed in this way affects the appearance of the window, the door or the like considerably because the locking rods protruding from the housing as additional locking bars have to be made relatively bulky if they are to fulfill the intended function of burglar resistance.

Es wurde auch schon erkannt, daß es zur Erzielung einer einbruchhemmenden Zusatzverriegelung der Flügel von Fenstern, Türen od. dgl. in den meisten Einsatzfällen nicht notwendig ist, einen Zusatz-Treibstangenbeschlag der durch die DE 38 34 373 A1 bzw. durch DE 38 44 627 A1 bekannt gewordenen Art in Benutzung zu nehmen. Man hat deshalb einbruchhemmende Zusatzverriegelungen entwickelt, welche zwischen Flügel und Blendrahmen lediglich in enger Nachbarschaft zum Bedienungshandhebel für den bereits vorhandenen Treibstangenbeschlag, insbesondere Drehkipp-Beschlag, wirksam sind, wie das beispielsweise der DE 38 22 343 A1 bzw. dem DE 89 06 629 U1 entnommen werden kann. Da die einbruchhemmenden Zusatzverriegelungen dieser Art keine Verschlußstangen benutzen, sondern lediglich Zusatzriegel aufweisen, die aus einem oder mehreren jeweils um eine ortsfeste Achse im Gehäuse verschwenkbar gelagerten Hakenriegeln bestehen, beeinträchtigen sie die Optik des Fensters, der Tür od. dgl. in weit geringerem Maße als die von einem aufliegenden Zusatz-Treibstangenbeschlag gebildeten Zusatzverriegelungen.It has also been recognized that in order to achieve a burglar-resistant additional locking of the sash of windows, doors or the like in most It is not necessary to use an additional connecting rod fitting of the type disclosed by DE 38 34 373 A1 or DE 38 44 627 A1. Burglar-resistant additional interlocks have therefore been developed, which are effective between the sash and the frame only in close proximity to the operating hand lever for the existing connecting rod fitting, in particular a tilt and turn fitting, such as that found in DE 38 22 343 A1 and DE 89 06 629 U1 can be. Since the burglar-resistant additional locks of this type do not use locking rods, but only have additional bolts which consist of one or more hook bolts each pivotably mounted about a fixed axis in the housing, they impair the appearance of the window, the door or the like to a much lesser extent than the additional locks formed by an additional connecting rod fitting.

Nachteilig bei den einbruchhemmenden Zusatzverriegelungen nach DE 38 22 343 A1 und nach DE 89 06 629 U1 ist jedoch, daß im Nachrüstungsfalle, also dann, wenn bereits eingebaute Fenster, Türen od. dgl. mit einer Zusatzverriegelung ausgestattet werden sollen, der dem vorhandenen Treibstangenbeschlag, insbesondere Drehkipp-Beschlag, zugeordnete Bedienungshandhebel mit Lagerrosette entfernt und insgesamt durch die mit einem eigenen Bedienungshandhebel ausgerüstete Zusatzverriegelung ersetzt werden muß.A disadvantage of the burglar-resistant additional locks according to DE 38 22 343 A1 and according to DE 89 06 629 U1 is, however, that in the event of retrofitting, that is, when already installed windows, doors or the like are to be equipped with an additional lock that matches the existing connecting rod fitting, in particular turn-tilt fitting, assigned operating hand lever with bearing rosette removed and overall must be replaced by the additional lock equipped with its own operating hand lever.

Nachteilig bei allen einbruchhemmenden Zusatzverriegelungen der vorstehend ab- gehandelten Art ist, daß das Ein- und Ausrücken der Zusatzriegel relativ zu den auf der raumseitigen Stirnfläche des Blendrahmens verankerten Einschlußteilen in zwangsläufiger Abhängigkeit von der Betätigung des den Treibstangenbeschlag, insbesondere Drehkipp-Beschlag, umstellenden Bedienungshandhebels steht. D.h., die Zusatzriegel der Zusatzverriegelung werden immer dann in Eingriffsstellung mit dem blendrahmenseitigen Einschlußteil gebracht, wenn über den Bedienungshandhebel die Umstellung des Treibstangenbeschlages in seine Verschluß-Schaltstellung erfolgt. Andererseits werden sie aber auch in die Ausrückstellung bewegt, sobald der Bedienungshandhebel des Treibstangenbeschlages aus seiner Verschluß-Schaltstellung verlagert wird.A disadvantage of all burglar-resistant additional locks of the type dealt with above is that the engagement and disengagement of the additional bolts relative to the inclusion parts anchored on the face-side end face of the frame is inevitably dependent on the actuation of the operating hand lever which adjusts the connecting rod fitting, in particular a tilt and turn fitting . That is, the additional bolts of the additional locking mechanism are always brought into engagement position with the cover part on the frame side when the shifting of the connecting rod fitting into its closed switch position takes place via the operating hand lever. On the other hand, they are also in the Release position moves as soon as the operating lever of the connecting rod fitting is shifted from its locking switch position.

Die Erfindung zielt auf die Schaffung einer Vorrichtung zur einbruchhemmenden Zusatzverriegelung der Flügel von Fenstern, Türen od. dgl. mit den eingangs erwähnten Gattungsmerkmalen ab, welche ein Zusammenwirken mit dem üblicherweise in einer Lagerrosette sitzenden Bedienungshandhebel eines Treibstangenbeschlages, insbesondere eines Drehkipp-Beschlages, ermöglicht, dabei aber zugleich sicherstellt, daß sich der oder die Zusatzriegel unabhängig von diesem Bedienungshandhebel in Eingriffsstellung und in Ausrückstellung bringen lassen. Zugleich kommt es aber darauf an, daß die Betätigung des Treibstangenbeschlages, insbesondere Drehkipp-Beschlages, über den Bedienungshandhebel und die hiervon getrennte Betätigung des oder der Zusatzriegel miteinander koordiniert werden.The invention aims to provide a device for burglar-resistant additional locking of the sash of windows, doors or the like with the generic features mentioned at the outset, which enables interaction with the operating hand lever of an espagnolette fitting, in particular a turn-tilt fitting, which is usually seated in a bearing rosette, but at the same time ensures that the additional bolt or bolts can be brought into the engaged position and the disengaged position independently of this operating hand lever. At the same time, however, it is important that the actuation of the drive rod fitting, in particular a tilt and turn fitting, are coordinated with one another via the operating hand lever and the separate actuation of the additional bolt or bolts.

Gelöst wird diese Aufgabe nach der Erfindung dadurch,

  • daß als Stellglied für den bzw. die Zusatzriegel eine beabstandet vom Durchgangsbereich für den Antriebsdorn des Bedienungshandhebels im Gehäuse gelagerte Zusatz-Handhabe vorgesehen ist.
  • daß das den Zusatzriegel enthaltende Gehäuse im Durchgangsbereich für den Antriebsdorn des Bedienungshandhebels eine mit diesem drehfest kuppelbare Nockenscheibe lagert,
  • daß diese Nockenscheibe an ihrem Umfang mit mehreren, nämlich mindestens zwei, zueinander drehwinkelversetzten und wenigstens bereichsweise geradlinig begrenzten Nockenflächen versehen ist,
  • daß die geradlinig begrenzten Nockenflächen mit unterschiedlichem Radialabstand von der Drehachse der Nockenscheibe vorgesehen sind,
  • daß in dem den Zusatzriegel enthaltenen Gehäuse ein Schieber auf einer Normalebene zur Drehachse der Nockenscheibe und zur Drehachse des Bedienungshandhebels bzw. Drehantriebsdorns begrenzt verlagerbar ist, welcher mit seinem einen Ende der Bewegungsbahn der Zusatz-Handhabe und mit seinem anderen Ende der Bewegungsbahn der Nockenscheibe zugewendet ist,
  • und daß dabei der Schieber eine Länge aufweist, mit der er innerhalb des Gehäuses wechselseitig entweder die Bewegungsbahn der Nockenscheibe oder die Bewegungsbahn der Zusatzhandhabe blockiert.
This object is achieved according to the invention by
  • that an additional handle is provided in the housing, spaced from the passage area for the drive pin of the operating hand lever, as an actuator for the additional latch (s).
  • that the housing containing the additional bolt in the passage area for the drive mandrel of the operating hand lever supports a cam disk which can be coupled in a rotationally fixed manner,
  • that this cam disk is provided on its circumference with several, namely at least two, cam surfaces which are offset from one another by an angle of rotation and at least partially rectilinearly limited,
  • that the straight-lined cam surfaces are provided with different radial distances from the axis of rotation of the cam disk,
  • that in the housing containing the additional bolt, a slide can be displaced on a normal plane to the axis of rotation of the cam disk and to the axis of rotation of the operating hand lever or rotary drive mandrel, which is turned with one end of the movement path of the additional handle and with its other end the movement path of the cam disc ,
  • and that the slide has a length with which it mutually blocks either the path of movement of the cam disc or the path of movement of the additional handle within the housing.

Besonders bewährt hat sich dabei eine Auslegung der einbruchhemmenden Zusatzverriegelung, welche bei in Eingriffsstellung gebrachtem Zusatzriegel die ungehinderte Schaltung des Bedienungshandhebels für den Treibstangenbeschlag in jede mögliche Funktionsstellung zuläßt, die aber ein Verlagern des Zusatzriegels aus seiner Eingriffsstellung in die Ausrückstellung erst ermöglicht, nachdem zuvor der Bedienungshandhebel des Treibstangenbeschlages aus seiner Grund-Schaltstellung - vornehmlich der Verschluß-Schaltstellung - in die nächste bzw. nachfolgende Schaltstellung - die Drehöffnungs-Schaltstellung - gebracht ist und die bei Ausrückstellung des Zusatzriegels die Rückschaltung des Bedienungshandhebels in seine Grund-Schaltstellung - die Verschluß-Schaltstellung - blockiert, dessen Weiterbewegung in die End-Schaltstellung - insbesondere die Kippöffnungs-Schaltstellung - aber zuläßt.A design of the burglar-resistant additional locking system has proven particularly useful, which, when the additional locking bar is in the engaged position, allows the unhindered switching of the operating lever for the espagnolette fitting into any possible functional position, but which only enables the additional bolt to be moved from its engaged position to the disengaged position after the operating hand lever has been operated beforehand of the espagnolette fitting from its basic switch position - primarily the lock switch position - into the next or subsequent switch position - the rotary opening switch position - and which, when the additional bolt is disengaged, switches the operating lever back into its basic switch position - the lock switch position - blocked, its further movement into the end switch position - in particular the tilt opening switch position - but allows.

Besondere Weiterbildungsmaßnahmen des Gegenstandes der Erfindung ergeben sich aus den Unteransprüchen 2 bis 11.Special training measures for the subject matter of the invention result from subclaims 2 to 11.

Der Schieber ist über die an seinem einen Ende angreifende Zusatz-Handhabe bei der Bewegung des Zusatzriegels in seine Ausrückstellung mit seinem anderen Ende blockierend in die Bewegungsbahn der Nockenscheibe stellbar, während er bei in Eingriffsstellung befindlichem Zusatzriegel mit seinem einen Ende durch die auf sein anderes Ende einwirkende Nockenscheibe blockierend in die Bewegungsbahn der Zusatz-Handhabe gestellt wird.The slider can be placed in the path of movement of the cam disc via the additional handle which engages at one end when the additional bolt is moved into its disengaging position, while its other end is in the engaged position when the additional bolt is in engagement position acting cam disk is placed blocking in the path of movement of the additional handle.

Dem Zusatzriegel und/oder der Zusatz-Handhabe ist im Gehäuse in besonders vorteilhafter Weise eine Schaltsperre zugeordnet, die bei in Schließlage am Blendrahmen liegendem Flügel über einen blendrahmenseitigen Anschlag gegen Rückstellwirkung eines Kraftspeichers, z.B. einer Feder, in einer Freigabestellung gehalten wird, während sie bei vom Blendrahmen abgehobenem Flügel unter der Wirkung des Kraftspeichers gegen den Zusatzriegel vorgespannt ist, und zwar derart, daß der Zusatzriegel in seiner Ausrückstellung durch die Schaltsperre blockierbar ist.The additional bolt and / or the additional handle is assigned in the housing in a particularly advantageous manner a switch lock which is held in a release position against a restoring effect of an energy accumulator, for example a spring, when a sash is in the closed position on the frame against a restoring effect of a force accumulator, for example a spring, while it is at sash lifted from the frame under the effect of the energy accumulator against the additional bolt is biased, in such a way that the additional bolt in its disengaged position can be blocked by the shift lock.

Jeder Zusatzriegel besteht zweckmäßigerweise aus einem um eine ortsfeste Achse im Gehäuse verschwenkbar gelagerten Hakenriegel, welcher mit der Zusatz-Handhabe durch einen Mitnehmeransatz formschlüssig gekuppelt ist. Dabei trägt die Zusatz-Handhabe noch einen Exzenternocken, der einerseits als Stellglied für den Schieber sowie andererseits als Blockieransatz für den in Eingriffsstellung befindlichen Zusatzriegel wirksam ist.Each additional bolt expediently consists of a hook bolt which is pivotally mounted about a fixed axis in the housing and which is positively coupled to the additional handle by means of a driver attachment. The additional handle also carries an eccentric cam, which is effective on the one hand as an actuator for the slide and on the other hand as a blocking projection for the additional bolt in the engaged position.

Die dem Drehantriebsdorn des Bedienungshandhebels zugeordnete Nockenscheibe kann einerseits als Stellglied für den Schieber benutzt werden sofern sich der Zusatzriegel in seiner Eingriffsstellung befindet. Andererseits ist sie aber als Sperrglied für den Drehantriebsdorn des Bedienungshandhebels wirksam, sobald der Zusatzriegel seine Ausrückstellung einnimmt.The cam disk assigned to the rotary drive mandrel of the operating hand lever can be used on the one hand as an actuator for the slide if the additional bolt is in its engaged position. On the other hand, it is effective as a locking member for the rotary drive mandrel of the operating hand lever as soon as the additional bolt takes its disengaging position.

Bewährt hat es sich, wenn die Schaltsperre von einem im Zusatzriegel-Gehäuse geführten Schieber gebildet wird, der einerseits über sein aus dem Gehäuse herausragendes Ende mit dem blendrahmenseitigen Anschlag in Wirkverbindung tritt, während er andererseits einen Sperrnocken trägt, welcher bei in Ausrückstellung befindlichem Zusatzriegel unter der Wirkung des Kraftspeichers in die Bewegungsbahn einer Blockiernase am Zusatzriegel stellbar ist.It has proven useful if the shift lock is formed by a slide guided in the additional bolt housing, which on the one hand comes into active connection with the stop on the frame side via its end protruding from the housing, while on the other hand it carries a locking cam which, when the additional bolt is in the disengaged position, is underneath the effect of the energy accumulator in the movement path of a blocking nose on the additional bolt is adjustable.

Das Zusatzriegel-Gehäuse läßt sich an seiner mit der Austrittsöffnung für den Zusatzriegel und der Austrittsöffnung für den Schieber der Schaltsperre versehenen Seite mit einer über die Bodenfläche vorspringenden Anschlagkante versehen, die mit der Längskante des Flügelüberschlags als Ausrichtmittel in Wirkverbindung tritt. Darüber hinaus kann das Zusatzriegel-Gehäuse in den Durchgangsbereichen für den Antriebsdorn des Bedienungshandhebels sowie auch in den Durchgangsbereichen der Ankerschrauben für dessen Lagerrosette sowohl in seiner Decke als auch in seinem Boden jeweils drei quer zur Anschlagkante gerichtete Langlöcher aufweisen, wobei die mittleren Langlöcher in Gehäusedecke und -boden Lagerbunde der Nockenscheibe aufnehmen, während die beiden äußeren Langlöcher der Gehäusedecke Halte- und Führungseingriffe für Fixierzapfen bilden, die sich rückseitig an der Lagerrosette des Bedienungshandhebels befinden.The additional bolt housing can be provided on its side provided with the outlet opening for the additional bolt and the outlet opening for the slide of the shift lock with a stop edge projecting over the bottom surface, which comes into operative connection with the longitudinal edge of the wing flap as an alignment means. In addition, the additional bolt housing in the passage areas for the drive mandrel of the operating hand lever and also in the passage areas of the anchor bolts for its bearing rosette each have three oblong holes directed transversely to the stop edge, both in its cover and in its base, the middle elongated holes in the housing cover and -ground Take up the collar of the cam disc, while the two outer elongated holes in the housing cover form holding and guiding interventions for fixing pins, which are located on the rear of the bearing rose of the operating lever.

Für eine ordnungsgemäße Zuordnung der einbruchhemmenden Zusatzverriegelung zum Flügel von Fenstern und Türen od. dgl. hat es sich als vorteilhaft erwiesen, wenn die Nockenscheibe durch abscherbare Nasen an den Lagerbunden in den Langlöchern von Decke und Boden des Zusatzriegel-Gehäuses mit einer vorbestimmten Dreh- und Schiebelage fixiert ist. Beim Anschlagen der Vorrichtung am Flügel lassen sich die als Sollbruchstellen wirksamen abscherbaren Nasen problemlos überwinden, wonach die Nockenscheibe die Bewegung des Bedienungshandhebels bzw. seines Drehantriebsdorns formschlüssig mitmacht.For a correct assignment of the burglar-resistant additional locking device to the sash of windows and doors or the like, it has proven to be advantageous if the cam disk can be sheared off by lugs on the bearing collars in the elongated holes of the ceiling and floor of the additional locking device housing with a predetermined turning and Sliding position is fixed. When the device is attached to the wing, the shearable lugs, which act as predetermined breaking points, can be easily overcome, after which the cam disc positively follows the movement of the operating hand lever or its rotary drive mandrel.

Es hat sich auch als vorteilhaft herausgestellt, wenn die Lagerachse des Zusatzriegels im Zusatzriegel-Gehäuse einen festliegenden Abstand von der mit der Anschlagkante für den Flügelüberschlag versehenen Gehäusebegrenzung aufweist, welcher kleiner bemessen ist, als alle Achsabstände der Langlöcher von dieser Anschlagkante. Hierdurch wird erreicht, daß die Zusatz-Handhabe für die Betätigung des Zusatzriegels immer frei zugänglich bleibt, unabhängig davon, welchen Achsabstand der Bedienungshandhebel bzw. sein Drehantriebsdorn jeweils von der Anschlagkante des Zusatzriegel-Gehäuses einnimmt. Die einbruchhemmende Zusatzverriegelung ist als - innerhalb vorgegebener Grenzen - zusammen mit Treibstangenbeschlägen einsetzbar, deren Betätigungsgetriebe unterschiedliche Dornmaße haben.It has also proven to be advantageous if the bearing axis of the additional bolt in the additional bolt housing is at a fixed distance from the housing boundary provided with the stop edge for the sash flap, which is smaller than all axial distances of the elongated holes from this stop edge. This ensures that the additional handle for actuating the additional bolt always remains freely accessible, regardless of the center distance of the operating hand lever or its rotary drive mandrel from the stop edge of the additional bolt housing. The burglar-resistant additional locking device can be used as - within specified limits - together with espagnolette fittings, the actuating gear of which have different backset dimensions.

Vornehmlich ist die erfindungsgemäße Vorrichtung zur einbruchhemmenden Zusatzverriegelung für eine Benutzung in Verbindung mit Drehkipp-Beschlägen vorgesehen, deren Betätigungsgetriebe über den Bedienungshandhebel in Drehwinkelschritten von jeweils 90° aus einer Verschluß-Schaltstellung über eine Drehöffnungs-Schaltstellung in eine Kippöffnungs-Schaltstellung bewegbar ist. Deshalb wird vorgeschlagen, die mit dem Antriebsdorn des Bedienungshandhebels kuppelbare Nockenscheibe einerseits mit Nockenflächen zu versehen, über die in der Verschluß-Schaltstellung des Bedienungs-Handhebel durch den Schieber die Eingriffsstellung des Zusatzriegels blockiert ist, während die Nockenscheibe andererseits Nockenflächen hat, über die in der Ausrückstellung des Zusatzriegels der Schaltweg des in der Drehöffnungs-Schaltstellung befindlichen Bedienungshandhebels in Richtung zur Verschluß-Schaltstellung hin blockiert ist.The device according to the invention for burglar-resistant additional locking is primarily intended for use in conjunction with tilt-and-turn fittings, the actuating gear of which can be moved via the operating hand lever in incremental angles of 90 ° in each case from a locking switch position via a rotary opening switching position to a tilt opening switching position. It is therefore proposed that the cam disc, which can be coupled to the drive mandrel of the operating hand lever, has cam surfaces on the one hand to be provided, via which the engagement position of the additional bolt is blocked by the slider in the closed switching position of the operating hand lever, while the cam disk, on the other hand, has cam surfaces, via the switching path of the operating hand lever located in the rotary opening switching position in the direction of disengagement of the additional bolt is blocked towards the closed switch position.

In Fig. 4 der Zeichnung sind von einem Fenster oder einer Tür 1 der verschlußseitige, aufrechte Holm des Blendrahmens 2 und der verschlußseitige aufrechte Holm des Flügels 3 jeweils im Querschnitt dargestellt. Dabei ist in den Flügel 3 verdeckt ein Treibstangenbeschlag 4, nämlich ein Eingriff-Drehkippbeschlag, herkömmlicher Art eingesetzt, von dem dabei lediglich eine Treibstange 5 eine Stulpschiene 6 und das Gehäuse 7 eines Betätigungsgetriebes zu sehen ist.In Fig. 4 of the drawing of a window or a door 1 of the upright spar of the frame 2 on the lock side and the upright spar of the wing 3 on the lock side are each shown in cross section. A drive rod fitting 4, namely an engagement turn-tilt fitting, of conventional type is concealed in the wing 3, of which only a drive rod 5, a faceplate 6 and the housing 7 of an actuating gear can be seen.

Im Gehäuse 7 des Betätigungsgetriebes steht ein - nicht gezeigtes Drehantriebsglied, beispielsweise in Form eines Ritzels, mit der Treibstange 5 in Antriebseingriff, mit dem der Drehantriebsdorn 8, vornehmlich ein Vierkantdorn, in formschlüssigen Steckeingriff gebracht ist, welcher durch einen Bedienungshandhebel 9 in Winkelschritten von jeweils 90° gedreht werden kann.In the housing 7 of the actuating gear is a - not shown rotary drive member, for example in the form of a pinion, with the drive rod 5 in drive engagement, with which the rotary drive mandrel 8, primarily a square mandrel, is brought into a form-fitting plug-in engagement, which by an operating hand lever 9 in angular steps of each Can be rotated 90 °.

Wie aus Fig. 3 und Fig. 4 ersichtlich ist, sitzen Bedienungshandhebel 9 und Drehantriebsdorn 8 in einer Lagerrosette 10, welche mit dem Gehäuse 7 des Betätigungsgetriebes über Ankerschrauben 11 zu verbinden ist, die den Holm des Flügels 3 durchsetzen. Der Treibstangenbeschlag 4 mit Drehantriebsdorn 8, Bedienungshandhebel 9, Lagerrosette 10 und Ankerschrauben 11 gehört zur Normalausstattung eines Fensters, einer Tür od. dgl., und zwar insbesondere auch dann, wenn der Flügel 3 mit dem Blendrahmen 2 ein Drehkippfenster bzw. eine Drehkipptür bildet.As can be seen from FIGS. 3 and 4, the operating hand lever 9 and rotary drive mandrel 8 are seated in a bearing rosette 10 which is to be connected to the housing 7 of the actuating gear via anchor bolts 11 which pass through the spar of the wing 3. The espagnolette fitting 4 with rotary drive mandrel 8, operating hand lever 9, bearing rosette 10 and anchor bolts 11 is part of the standard equipment of a window, a door or the like, in particular also when the sash 3 forms a tilt-and-turn window or a tilt-and-tilt door with the window frame 2.

Fenster und Türen 1 mit dieser normalen Treibstangenbeschlag-Ausstattung sind - insbesondere beim Einsatz in den unteren Stockwerken bzw. Etagen von Gebäuden - relativ anfällig gegen unbefugte äußere Einwirkungen auf den Treibstangenbeschlag; d.h., mit relativ einfachen Werkzeugen können die Treibstangenbeschläge von außen her so beeinflußt werden, daß sich der Flügel 3 relativ zum Blendrahmen 2 zum Einstieg öffnen läßt.Windows and doors 1 with this normal espagnolette fitting are relatively susceptible to unauthorized external influences on the espagnolette fitting, particularly when used on the lower floors or floors of buildings; i.e., with relatively simple tools, the espagnolette fittings can be influenced from the outside in such a way that the wing 3 can be opened relative to the frame 2 for entry.

Deshalb ist es oft erwünscht oder sogar Bedingung, die Fenster und Türen 1 in den unteren Stockwerken bzw. Etagen von Gebäuden - auch nachträglich noch - mit einer einbruchhemmenden Zusatzverriegelung 13 auszustatten.Therefore, it is often desirable or even a requirement to provide the windows and doors 1 on the lower floors or floors of buildings - even subsequently - with an additional burglar-resistant locking device 13.

Deren Aufbau und Wirkungsweise wird nachfolgend in allen Einzelheiten anhand der Fig. 1 bis 7 der Zeichnung erläutert.Their structure and mode of operation is explained in detail below with reference to FIGS. 1 to 7 of the drawing.

Den Fig. 3 und 4 kann dabei entnommen werden, daß die Zusatzverriegelung 13 auf die raumseitige Stirnfläche 14 des Flügels 3 aufgesetzt wird, und zwar als ein Nachrüst- und/oder Ergänzungselement, welches unter die Lagerrosette 10 des üblichen Bedienungshandhebels 9 für den eigentlichen Treibstangenbeschlag 4 gesetzt ist. Dabei hat diese Zusatzverriegelung 13 ein im wesentlichen rechteckig begrenztes und relativ flach ausgeführtes Gehäuse 15, das durch eine Bodenplatte 16 verschlossen wird, wie sie in den Fig. 3 und 7 zu sehen ist.3 and 4 can be seen that the additional lock 13 is placed on the room-side end face 14 of the wing 3, as a retrofit and / or supplementary element, which under the bearing rosette 10 of the usual operating lever 9 for the actual drive rod fitting 4 is set. This additional locking device 13 has an essentially rectangularly delimited and relatively flat housing 15 which is closed by a base plate 16, as can be seen in FIGS. 3 and 7.

Zwischen der Bodenplatte 16 und der Decke 17 des Gehäuses 15 ist wenigstens ein Zusatzriegel 17 beweglich gelagert, und zwar beabstandet vom Durchgangsbereich für den Drehantriebsdorn 8 des Bedienungshandhebels 9. Dieser Zusatzriegel 8 besteht dabei aus einem um eine ortsfeste Achse 19 19 verschwenkbar im Gehäuse 15 gelagerten Hakenriegel, welcher sich mit Hilfe einer Zusatz-Handhabe 20 zwischen seiner Ausrückstellung nach Fig. 1 und seiner Eingriffsstellung nach Fig. 2 verlagern läßt. Die Zusatz-Handhabe 20 ist dabei in den Fig. 3 und 4 der Zeichnung zu sehen und auf der Oberseite der Decke 17 des Gehäuses 15 angeordnet. Sie lagert mit einem Hals 21 in der Decke 17 sowie mit einem hierzu fluchtenden Zapfen 22 im Boden 18 des Gehäuses 15. Ein Mitnehmeransatz 23 der Zusatz-Handhabe 20 durchsetzt formschlüssig einen Mitnehmerausschnitt 24 im Zusatzriegel 8, an welchen sich zum Zapfen 22 hin drehfest wiederum ein Exzenternocken 25 anschließt.At least one additional bolt 17 is movably mounted between the base plate 16 and the ceiling 17 of the housing 15, at a distance from the passage area for the rotary drive mandrel 8 of the operating hand lever 9. This additional bolt 8 consists of a pivotable in the housing 15 about a fixed axis 19 19 Hook bolt, which can be shifted between its disengagement position according to FIG. 1 and its engagement position according to FIG. 2 with the aid of an additional handle 20. The additional handle 20 can be seen in FIGS. 3 and 4 of the drawing and is arranged on the top of the ceiling 17 of the housing 15. It rests with a neck 21 in the ceiling 17 and with a pin 22 in alignment in the bottom 18 of the housing 15. A driver lug 23 of the additional handle 20 positively penetrates a driver cutout 24 in the additional bar 8, on which turn in turn to the pin 22 against rotation an eccentric cam 25 connects.

Zwischen der Decke 17 und dem Boden 18 des Gehäuses 15 lagert darüberhinaus im Durchgangsbereich für den Drehantriebsdorn 8 des Bedienungshandhebels 9 eine mit diesem drehfest kuppelbare Nockenscheibe 26, wie sie für sich allein in größerem Maßstab in Draufsicht und Seitenansicht aus Fig. 5 der Zeichnung ersichtlich ist. Diese Nockenscheibe 26 hat dabei zwei seitlich abgesetzte Bunde 27, von denen einer in ein Langloch 28 der Decke 17 des Gehäuses 15 und der andere in ein entsprechendes Langloch 29 in der Bodenplatte 16 eingreift.Between the ceiling 17 and the bottom 18 of the housing 15, in addition, a cam disk 26, which can be coupled with it in a rotationally fixed manner, is mounted in the passage area for the rotary drive mandrel 8 of the operating lever 9, as can be seen on a larger scale alone in plan view and side view from FIG. 5 of the drawing . This cam disk 26 has two laterally offset collars 27, one of which is in an elongated hole 28 of the ceiling 17 of the Housing 15 and the other engages in a corresponding slot 29 in the base plate 16.

Fluchtend mit den Längsachsen der beiden Bunde 27 ist die Nockenscheibe 26 mit einem Mehrkantdurchlaß 30 - beispielsweise einem Vierkantdurchlaß versehen, dessen Querschnittsabmessung mit dem Drehantriebsdorn 8 des Bedienungshandhebels 9 übereinstimmt, so daß dieser den Durchlaß 30 in Richtung zum Gehäuse 7 des Betätigungsgetriebes für den Treibstangenbeschlag 4 hin formschlüssig und drehfest durchsetzen kann.Aligning with the longitudinal axes of the two collars 27, the cam disk 26 is provided with a polygonal passage 30 - for example a square passage, the cross-sectional dimension of which coincides with the rotary drive mandrel 8 of the operating hand lever 9, so that this passage 30 in the direction of the housing 7 of the actuating gear for the connecting rod fitting 4 can positively and non-rotatably enforce.

An ihrem Umfang weist die Nockenscheibe 26 mehrere - nämlich mindestens zwei - zueinander drehwinkelversetzte und wenigstens bereichsweise geradlinig begrenzte Nockenflächen 31 und 32 auf. Die Nockenfläche 31 hat dabei von der Drehachse 33 der Nockenscheibe 26 einen großen Radialabstand 34, während die Nockenfläche 32 hiervon einen kleineren Radialabstand 35 aufweist. Der Winkelabstand zwischen den beiden Nockenflächen 31 und 32 ist auf 90° festgelegt, wobei sich die geradlinige Nockenfläche 31 über ein zur Drehachse 33 konzentrisches Bogenstück 36 an die ebenfalls geradlinige Nockenfläche 32 anschließt. Von der geradlinigen Nockenfläche 32 ist wiederum ein zur Drehachse konzentrisches Bogenstück 37 über einen Winkelbereich von 90° geführt.On its circumference, the cam disk 26 has a plurality of cam surfaces 31 and 32 which are offset from one another by an angle of rotation and at least partially rectilinearly limited, namely at least two. The cam surface 31 has a large radial distance 34 from the axis of rotation 33 of the cam disk 26, while the cam surface 32 has a smaller radial distance 35 therefrom. The angular distance between the two cam surfaces 31 and 32 is fixed at 90 °, the rectilinear cam surface 31 adjoining the rectilinear cam surface 32 via an arc piece 36 concentric with the axis of rotation 33. From the rectilinear cam surface 32, an arc piece 37, which is concentric with the axis of rotation, is guided over an angular range of 90 °.

In Fig. 2 der Zeichnung ist diejenige Winkel-Drehlage der Nockenscheibe 26 um ihre Drehachse 33 zu sehen, welche der Grund-Schaltstellung, und zwar der Verschluß-Schaltstellung des Bedienungshandhebels 9 (vergl. auch Fig. 3) entspricht.2 of the drawing shows that angular-rotational position of the cam disk 26 about its axis of rotation 33 which corresponds to the basic switching position, namely the closed switching position of the operating hand lever 9 (cf. also FIG. 3).

Fig. 1 der Zeichnung gibt hingegen die Winkel-Drehlage der Nockenscheibe 26 um ihre Drehachse 33 wieder, welche der der Grund-Schaltstellung nachfolgenden Schaltstellung, nämlich der Drehöffnungs-Schaltstellung, des Bedienungshandhebels 9 entspricht. Diese hat eine um 90° zur Grund- bzw. Verschluß-Schaltstellung winkelversetzte Drehlage, wie sich aus einem Vergleich der mit dem Bezugszeichen 9 versehenen, strichpunktierten Linien in den Fig. 1 und 2 ergibt. Der Abstand bzw. die Distanz zwischen dem Arbeitsbereich des Exzenternockens 25 der Zusatz-Handhabe 20 für die Betätigung des Zusatzriegels 18 sowie dem Arbeitsbereich der Nockenscheibe 26 ist innerhalb des Gehäuses 15 durch einen Schieber 38 überbrückt. Dabei ist dieser Schieber (38) im Gehäuse 15 zwischen dessen Bodenplatte 16 und dem Zusatzriegel 18 auf einer Normalebene sowohl zur ortsfesten Achse 19-19 der Zusatz-Handhabe 20 als auch zu Drehachse 33 der Nockenscheibe (26) begrenzt verlagerbar vorgesehen. Über die Querkante 39 seines unteres Endes wirkt der Schieber (38) mit dem Exzenternocken 25 der Zusatz-Handhabe 20 zusammen, während die Querkante 40 seines oberen Endes mit der Nockenscheibe 26 in Wirkverbindung gehalten ist.1 of the drawing, on the other hand, shows the angular position of the cam disk 26 about its axis of rotation 33, which corresponds to the switching position following the basic switching position, namely the rotary opening switching position, of the operating hand lever 9. This has a rotational position offset by 90 ° to the basic or closed switching position, as can be seen from a comparison of the dash-dotted lines provided with the reference number 9 in FIGS. 1 and 2. The distance or the distance between the Working area of the eccentric cam 25 of the additional handle 20 for actuating the additional bolt 18 and the working area of the cam disk 26 is bridged within the housing 15 by a slide 38. This slide (38) is provided in the housing 15 between its base plate 16 and the additional bolt 18 on a normal plane both to the fixed axis 19-19 of the additional handle 20 and to the axis of rotation 33 of the cam disc (26) to a limited extent. The slide (38) interacts with the eccentric cam 25 of the additional handle 20 via the transverse edge 39 of its lower end, while the transverse edge 40 of its upper end is held in operative connection with the cam disk 26.

In die in den Fig. 2 und 3 angedeutete Grund- bzw. Verschluß-Schaltstellung läßt sich der Bedienungshandhebel 9 für den Treibstangenbeschlag 4, insbesondere einen Drehkipp-Beschlag, nur bringen, nachdem zuvor der Zusatzriegel 18 der Zusatzverriegelung 13 mit Hilfe der Zusatz-Handhabe 20 in seine Eingriffsstellung gebracht worden ist, wie sie den Fig. 2 und 4 entnommen werden kann. In diesem Falle ist dann nämlich der als Hakenriegel gestaltete Zusatzriegel 18 in ein auf die raumseitige Stirnfläche des Blendrahmens 2 aufgesetztes und dort verankertes Einschlußteil 41 eingerückt, wie es in den Fig. 2 und 4 zu sehen ist. Dabei nimmt der durch die Zusatz-Handhabe 20 verstellbare Exzenternocken 25 eine Schwenklage ein, bei der der Schieber 38 seine unterste Endstellung erreicht und mit seiner Querkante 39 auf ihm abgestützt ist (Fig. 2 ).In the basic or locking switch position indicated in FIGS. 2 and 3, the operating hand lever 9 for the connecting rod fitting 4, in particular a tilt and turn fitting, can be brought only after the additional latch 18 of the additional locking device 13 has been previously used with the additional handle 20 has been brought into its engagement position, as can be seen in FIGS. 2 and 4. In this case, the additional bolt 18 designed as a hook bolt is then inserted into an inclusion part 41 which is placed on the face-side end face of the frame 2 and anchored there, as can be seen in FIGS. 2 and 4. The eccentric cam 25, which can be adjusted by the additional handle 20, assumes a swivel position in which the slide 38 reaches its lowest end position and is supported on it with its transverse edge 39 (FIG. 2).

Zugleich hat die Nockenscheibe 26 eine Drehlage, bei der ihre den großen Radialabstand 34 von der Drehachse 33 aufweisende Nockenfläche 31 der oberen Querkante 40 des Schiebers 38 zugewendet ist und dieser eine starre Stützanlage bietet. Da sich folglich der Schieber 38 innerhalb des Gehäuses 15 nicht nach oben verlagern läßt, wird über den Exzenternocken 25 die Zusatz-Handhabe 20 und mit ihr der Zusatzriegel 18 gegen Verschwenken aus seiner Eingriffsstellung (Fig. 2 und 4) blockiert.At the same time, the cam disk 26 has a rotational position in which its cam surface 31, which has the large radial distance 34 from the axis of rotation 33, faces the upper transverse edge 40 of the slide 38 and this offers a rigid support system. Since consequently the slider 38 cannot be displaced upward within the housing 15, the additional handle 20 and with it the additional latch 18 is blocked against pivoting out of its engaged position (FIGS. 2 and 4) via the eccentric cam 25.

Da sich an die gerade Nockenfläche 31 der Nockenscheibe 26 ein um deren Drehachse 33 gekrümmtes Bogenstück 36 anschließt, läßt die Nockenscheibe (26) jedoch relativ zur oberen Querkante 40 des Schiebers 38 eine Schwenkbewegung zu, die in Fig. 2 im Uhrzeigersinn gerichtet ist. Deshalb ist auch der Bedienungshandhebel 9 für den Treibstangenbeschlag 4 bei der aus Fig. 2 ersichtlichen Wirkstellung der Zusatzverriegelung 13 nicht gegen eine entsprechende Schwenkbewegung (im Uhrzeigersinn) blockiert. Er läßt sich deshalb aus seiner Grund- bzw. Verschluß-Schaltstellung nicht nur um 90° in die Drehöffnungs-Schaltstellung gemäß Fig. 1 bringen, sondern bei Bedarf auch um 180° bis in die Kippöffnungs-Schaltstellung verlagern, wie sie bei einem Drehkipp-Beschlag üblicherweise ebenfalls vorhanden ist.Since the straight cam surface 31 of the cam disk 26 is followed by an arc piece 36 curved about its axis of rotation 33, the cam disk can be (26), however, a pivoting movement relative to the upper transverse edge 40 of the slide 38, which is directed clockwise in FIG. 2. Therefore, the operating hand lever 9 for the connecting rod fitting 4 is not blocked against a corresponding pivoting movement (clockwise) in the active position of the additional locking device 13 shown in FIG. 2. It can therefore not only be brought from its basic or closed switching position by 90 ° into the rotary opening switching position according to FIG. 1, but if necessary it can also be shifted by 180 ° to the tilt opening switching position, as is the case with a tilt and turn Fitting is usually also present.

Durch eine Winkeldrehung des Bedienungshandhebels 9 um 90° aus seiner Grund- bzw. Verschluß-Schaltstellung nach Fig. 2 in die nächste Schaltstellung, nämlich die Drehöffnungs-Schaltstellung gemäß Fig. 1, wird die Nockenscheibe 26 mit ihrer Nockenfläche 32 in Parallellage zur oberen Querkante 40 des Schiebers 38 eingestellt. Da die Nockenfläche 32 einen kleineren Radialabstand 35 von der Drehachse 33 der Nockenscheibe 26 hat, weist zunächst die Querkante 40 des Schiebers 38 einen entsprechenden Abstand von dieser Nockenfläche 32 auf. Hierdurch bedingt, wird dann die Blockierung des Exzenternockens 25 durch die untere Querkante 39 des Schiebers 38 aufgehoben. Mit Hilfe der Zusatz-Handhabe 20 läßt sich folglich der Exzenternocken 26 und mit ihm natürlich auch der Zusatzriegel 18 aus der Eingriffsstellung der Fig. 2 und 4 in die Ausrückstellung der Fig. 1 verlagern. Hierbei wird dann der Schieber 38 nach oben bewegt, bis sich seine obere Querkante 40 gegen die Nockenfläche 32 der Nockenscheibe 26 stützend anlegt, wie das die Fig. 1 deutlich zeigt. Damit dann der Bedienungshandhebel 9 für den Treibstangenbeschlag 4 gegen eine Rückstellbewegung aus seiner Drehöffnungs-Schaltstellung in Richtung zur Grund- bzw. Verschluß-Schaltstellung wirksam blockiert. Hingegen wird eine Weiterbewegung des Bedienungshandhebels 9 aus der Drehöffnungs-Schaltstellung in die Kippöffnungs-Schaltstellung nicht behindert, weil sich in der betreffenden Bewegungsrichtung an die gerade Nockenfläche 32 das Bogenstück 37 konzentrisch um die Drehachse 33 anschließt.By an angular rotation of the operating lever 9 by 90 ° from its basic or closed switching position according to FIG. 2 into the next switching position, namely the rotary opening switching position according to FIG. 1, the cam disk 26 with its cam surface 32 is in parallel to the upper transverse edge 40 of the slider 38 set. Since the cam surface 32 has a smaller radial distance 35 from the axis of rotation 33 of the cam disk 26, the transverse edge 40 of the slide 38 is at a corresponding distance from this cam surface 32. As a result of this, the blocking of the eccentric cam 25 by the lower transverse edge 39 of the slide 38 is then released. With the help of the additional handle 20, the eccentric cam 26 and with it, of course, also the additional bolt 18 can be shifted from the engaged position of FIGS. 2 and 4 into the disengaged position of FIG. 1. Here, the slide 38 is then moved upwards until its upper transverse edge 40 bears against the cam surface 32 of the cam disk 26, as clearly shown in FIG. 1. So that the operating hand lever 9 for the connecting rod fitting 4 is effectively blocked against a return movement from its rotary opening switching position in the direction of the basic or locking switching position. On the other hand, a further movement of the operating hand lever 9 from the rotary opening switching position into the tilt opening switching position is not hindered because in the direction of movement in question the arc piece 37 concentrically connects to the straight cam surface 32 about the axis of rotation 33.

Soll die Rückstellung des Bedienungshandhebels 9 für den Treibstangenbeschlag 4 in seine Grund- bzw. Verschluß-Schaltstellung ermöglicht werden, dann ist es zunächst erst wieder erforderlich, den Zusatzriegel 18 über die Zusatz-Handhabe 20 von der Ausrückstellung gemäß Fig. 1 in die Eingriffsstellung nach den Fig. 2 und 4 zu bringen, damit durch die obere Querkante 40 des Schiebers 38 die Stützanlage für die Nockenfläche 32 der Nockenscheibe 26 freigegeben ist.If the reset of the operating lever 9 for the connecting rod fitting 4 to its basic or locking switch position is to be made possible, then it is first necessary again to move the additional bolt 18 via the additional handle 20 from the disengaged position according to FIG. 1 into the engagement position 2 and 4, so that the support system for the cam surface 32 of the cam disk 26 is released through the upper transverse edge 40 of the slide 38.

Eine Besonderheit der Zusatzverriegelung 13 besteht noch darin, daß der Zusatzriegel 18 über eine Schaltsperre 42 so lange in seiner Ausrückstellung nach Fig. 1 fixiert werden kann, wie sich der Flügel 3 des Fensters oder der Tür 1 noch nicht in seiner Schließlage am Blendrahmen 2 befindet. Folglich wird dann auch der Bedienungshandhebel 9 für den Treibstangenbeschlag 4 gegen Rückstellung aus seiner Drehöffnungs-Schaltstellung in die Grund- bzw. Verschluß-Schaltstellung blockiert, bis es möglich ist, den Zusatzriegel 18 aus seiner Ausrückstellung gemäß Fig. 1 in seine Eingriffsstellung nach den Fig. 2 und 4 zu bringen.A special feature of the additional locking device 13 is that the additional locking device 18 can be fixed in its disengaged position according to FIG. 1 via a switching lock 42 as long as the wing 3 of the window or the door 1 is not yet in its closed position on the frame 2 . Consequently, the operating hand lever 9 for the connecting rod fitting 4 is then blocked against resetting from its rotary opening switching position into the basic or locking switching position until it is possible to move the additional bolt 18 from its disengaged position according to FIG. 1 into its engagement position according to FIGS To bring 2 and 4.

Die Schaltsperre 42 weist einen im Gehäuse 15 zwischen dessen Decke 17 und der Bodenplatte 16 querbeweglichen Schieber 43 auf, der mit einem fallenartig abgeschrägten Ende 44 ständig aus einer Öffnung 45 in einer Längsseitenwand 46 des Gehäuses 15 herausragt. Das dem fallenartigen Ende 44 gegenüberliegende Ende des Schiebers 43 steht unter der ständigen Einwirkung eines Kraftspeichers 47, z.B. einer Feder, der das fallenartige Ende 44 aus dem Gehäuse 15 herausdrückt.The shift lock 42 has a slide 43 which can move transversely in the housing 15 between the ceiling 17 and the base plate 16 and which, with a trailing end 44, protrudes continuously from an opening 45 in a longitudinal side wall 46 of the housing 15. The end of the slide 43 opposite the trap-like end 44 is under the constant action of an energy store 47, e.g. a spring that pushes the trap-like end 44 out of the housing 15.

Wird der Flügel 3 relativ zum Blendrahmen 2 in Schließlage gebracht, dann trifft das fallenartige Ende 44 des Schiebers 43 auf einen blendrahmenseitigen Anschlag 48, beispielsweise am Einschlußteil 41. Dadurch wird der Schieber 43 entgegen der Rückstellwirkung des Kraftspeichers 47 in das Gehäuse 15 der Zusatzverriegelung 13 zurückgeschoben (Fig. 2).If the sash 3 is brought into the closed position relative to the frame 2, then the latch-like end 44 of the slider 43 meets a stop 48 on the frame side, for example on the inclusion part 41. As a result, the slider 43 is counter to the restoring effect of the energy accumulator 47 in the housing 15 of the additional locking device 13 pushed back (Fig. 2).

Ein Sperrnocken 49 des Schiebers 43 wird dadurch aus der Bewegungsbahn einer Blockiernase 50 gerückt, die sich am Zusatzriegel 18 befindet. Der Zusatzriegel 18 kann nunmehr aus der Ausrückstellung gemäß Fig. 1 in die Eingriffsstellung nach den Fig. 2 und 4 mit Hilfe der Zusatz-Handhabe 20 verlagert werden.A locking cam 49 of the slide 43 is thereby moved out of the movement path of a blocking nose 50, which is located on the additional bolt 18. The additional bolt 18 can now be moved from the disengaged position according to FIG. 1 into the engagement position according to FIGS. 2 and 4 with the aid of the additional handle 20.

Wird in der Ausrückstellung des Zusatzriegels 18 der Flügel 3 des Fensters oder der Tür 1 gegenüber dem Blendrahmen 2 in Öffnungsstellung bewegt, dann bewirkt die Schaltsperre 42 über den Schieber 43 die Festlegung des Zusatzriegels 18 in der aus Fig. 1 ersichtlichen Art und Weise, d.h., es wird nicht nur eine Fehlschaltung des Zusatzriegels 18 über die Zusatz-Handhabe 20 verhindert, sondern auch die Rückstellung des Bedienungshandhebels 9 für den Treibstangenbeschlag 4 in seine Grund- bzw. Verschluß-Schaltstellung unterbunden.If, in the disengaged position of the additional bolt 18, the wing 3 of the window or the door 1 is moved in the open position relative to the frame 2, then the shift lock 42 causes the additional bolt 18 to be fixed in the manner shown in FIG. 1, ie , It not only prevents the additional bolt 18 from switching incorrectly via the additional handle 20, but also prevents the operating lever 9 from being reset for the connecting rod fitting 4 into its basic or locked switching position.

Ein anderes wichtiges Ausbildungskriterium der als Nachrüst- und/oder Ergänzungselement ausgelegten Zusatzverriegelung 13 besteht darin, daß diese sich Flügeln 3 der Fenster oder Türen 1 problemlos zuordnen läßt, auch wenn diese innerhalb gewisser Grenzen unterschiedliche Profilquerschnitte haben. Insbesondere geht es dabei um die Zuordnungsmöglichkeit einundderselben Zusatzverriegelung 13 zu Profilquerschnitten der Flügel 3, die unterschiedliche Breitenabmessungen im Bereich des Flügelüberschlags haben.Another important training criterion of the additional locking 13 designed as a retrofit and / or supplementary element is that it can be easily assigned to leaves 3 of the windows or doors 1, even if these have different profile cross sections within certain limits. In particular, it is about the possibility of assigning one and the same additional locking device 13 to profile cross sections of the wings 3, which have different width dimensions in the area of the wing flap.

Zwecks einfacher Anpassung an diese unterschiedlichen Einbauverhältnisse weist das Gehäuse 15 der Zusatzverriegelung 13 einerseits im Durchgangsbereich für den Drehantriebsdorn 8 des Bedienungshandhebels 9 in seiner Decke 17 das Langloch 28 und in seiner Bodenplatte 16 das Langloch 29 auf, wobei sich beide Langlöcher 28 und 29 quer zur Längsrichtung des Gehäuses 15 erstrecken.For the purpose of simple adaptation to these different installation conditions, the housing 15 of the additional locking device 13 has the elongated hole 28 in the ceiling 17 on the one hand in the passage area for the rotary drive mandrel 8 of the operating hand lever 9 and the elongated hole 29 in its base plate 16, both elongated holes 28 and 29 being transverse to Extend the longitudinal direction of the housing 15.

Über das Quermaß 51 dieser Langlöcher 28 und 29 hinweg kann die Nockenscheibe 26 mit ihren Bunden 27 entsprechend der notwendigen Anpassung an unterschiedliche Flügelprofile verschoben werden. Auch in den Durchgangsbereichen für die Ankerschrauben 11 der Lagerrosette 10 des Bedienungshandhebels 9 ist das Gehäuse 15 in seiner Decke 17 mit Langlöchern 52a, 52b und in seiner Bodenplatte 16 mit Langlöchern 53a, 53b versehen, die ebenfalls ein Quermaß 51 aufweisen. Die Langlöcher 52a und 52b in der Decke 17 des Gehäuses 15 sind dabei so bemessen, daß sie sich zur Aufnahme von Fixierzapfen 54a und 54b eignen, die jeweils im Durchgangsbereich der Ankerschrauben 11 von der Rückseite der Lagerrosette 10 abstehen, wie das Fig. 3 der Zeichnung erkennen läßt. Die Langlöcher 53a und 53b in der Bodenplatte 16 sind demgegenüber mit genügendem Spiel lediglich auf den Schaftdurchmesser der Ankerschrauben 11 abgestimmt.Over the transverse dimension 51 of these elongated holes 28 and 29, the cam disk 26 with its collars 27 can be displaced in accordance with the necessary adaptation to different wing profiles. Even in the Passage areas for the anchor bolts 11 of the bearing rosette 10 of the operating lever 9, the housing 15 is provided in its ceiling 17 with elongated holes 52a, 52b and in its base plate 16 with elongated holes 53a, 53b, which also have a transverse dimension 51. The elongated holes 52a and 52b in the ceiling 17 of the housing 15 are dimensioned such that they are suitable for receiving fixing pins 54a and 54b, which each protrude in the passage area of the anchor bolts 11 from the rear of the bearing rosette 10, as shown in FIG Drawing shows. In contrast, the elongated holes 53a and 53b in the base plate 16 are only matched to the shaft diameter of the anchor bolts 11 with sufficient play.

Die ortsfeste Achse 19-19 des Zusatzriegels 18 und der Zusatz-Handhabe 20 im Gehäuse 15 hat einen Abstand 55 von der vorderen Längsseitenwand 46 des Gehäuses 15, welcher in jedem Falle kleiner bemessen ist als der über das Quermaß 51 hinweg in den Langlöchern 28 und 29 variierbare Abstand der Drehachse 33 der Nockenscheibe 26, welche über ihren Mehrkantdurchlaß 30 mit dem Drehantriebsdorn 8 des Bedienungshandhebels 9 kuppelbar ist. Dadurch bleibt die leichte Zugänglichkeit der Zusatz-Handhabe 20 unterhalb des Bedienungshandhebels 9 jederzeit erhalten.The stationary axis 19-19 of the additional bolt 18 and the additional handle 20 in the housing 15 has a distance 55 from the front longitudinal side wall 46 of the housing 15, which is in any case smaller than that across the transverse dimension 51 in the elongated holes 28 and 29 variable distance of the axis of rotation 33 of the cam disk 26, which can be coupled via its polygonal passage 30 to the rotary drive mandrel 8 of the operating lever 9. As a result, the easy accessibility of the additional handle 20 below the operating lever 9 is maintained at all times.

Am Umfang ihrer beiden Bunde 27 trägt die Nockenscheibe 26 je eine radial gerichtete, abscherbare Nase 56, die passend in einer Ausklinkung 57 fixiert wird, welche sich am Rand der Langlöcher 28 und 29 in der Gehäusedecke 17 und in der Bodenplatte 16 befindet. Hierdurch wird beim Zusammenbau der Zusatzverriegelung 13 die Nockenscheibe 26 im Gehäuse 15 mit einer vorbestimmten Dreh- und Schiebelage fixiert, bis deren Anschlag am Flügel 3 eines Fensters oder einer Tür 1 vorgenommen wird. Nachdem dabei der Drehantriebsdorn 8 des Bedienungshandhebels 9 durch den Mehrkantdurchlaß 30 der Nockenscheibe 26 gesteckt und in den entsprechenden Mehrkantdurchlaß des Drehantriebsgliedes im Betätigungsgetriebe des Treibstangenbeschlages 4 eingeführt ist, wird die Zusatzverriegelung 13 auf der raumseitigen Stirnfläche 14 des Flügels 3 verschoben, bis eine über die Bodenfläche ihres Gehäuses 15 vorstehende Anschlagkante 58 gegen die Überschlags-Umfangsfläche des Flügels 3 zur Anlage kommt, wie das deutlich aus Fig. 4 der Zeichnung entnehmbar ist. Erst daraufhin werden die Ankerschrauben 11 für die Lagerrosette 10 fest angezogen, um das Gehäuse 15 der Zusatzverriegelung 13 zwischen der Lagerrosette 10 des Bedienungshandhebels 9 und der raumseitigen Stirnfläche 14 des Flügels 3 festzuspannen.On the circumference of its two bundles 27, the cam disk 26 carries a radially directed, shearable nose 56, which is suitably fixed in a notch 57, which is located on the edge of the elongated holes 28 and 29 in the housing cover 17 and in the base plate 16. As a result, when the additional locking device 13 is assembled, the cam disk 26 is fixed in the housing 15 with a predetermined turning and sliding position until it stops on the wing 3 of a window or a door 1. After the rotary drive mandrel 8 of the operating lever 9 is inserted through the polygonal passage 30 of the cam disk 26 and inserted into the corresponding polygonal passage of the rotary drive member in the actuating gear of the connecting rod fitting 4, the additional locking device 13 is moved on the end face 14 of the wing 3 on the room side until one over the floor surface its housing 15 protruding stop edge 58 comes to rest against the rollover circumferential surface of the wing 3, as is clear 4 of the drawing can be seen. Only then are the anchor screws 11 for the bearing rosette 10 tightened in order to clamp the housing 15 of the additional locking device 13 between the bearing rosette 10 of the operating lever 9 and the end face 14 of the wing 3 on the room side.

An seinem unteren Ende hat das Gehäuse 15 der Zusatzverriegelung 13 noch ein Durchgangsloch, welches eine zusätzlich im Flügel 3 verankerbare Befestigungsschraube aufnehmen kann.At its lower end, the housing 15 of the additional locking device 13 also has a through hole which can accommodate an additional fastening screw which can be anchored in the wing 3.

Insbesondere den Fig. 3 und 4 der Zeichnung läßt sich entnehmen, daß die gesamte Zusatzverriegelung 13 verhältnismäßig niedrig baut und folglich an der raumseitigen Stirnfläche 14 des Flügels 3 nur einen entsprechend geringen Einbauraum benötigt.3 and 4 of the drawing in particular that the entire additional locking device 13 is of relatively low construction and consequently requires only a correspondingly small installation space on the end face 14 of the wing 3 on the room side.

    - the slide (38) has a length with which inside the casing (15) it alternately blocks either the path of motion of the cam (26) or the path of motion (25) of the additional handle (20).
  2. A mechanism according to claim 1, characterised in that the slide (38), via the additional handle (20) engaging one end (39) thereof, when the additional bolt (18) moves into its disengaged position (Fig. 1), can be positioned so that its other end (40) blocks the path of motion of the cam (26), whereas when the additional bolt (18) is in the engaged position (Fig. 2) the first-mentioned end (39) is adjustable by the cam (26) acting on the other end (40) so as to block the path of motion (25) of the additional handle (20).
  3. A device according to claim 1 or 2, characterised in that the additional bolt (18) and/or the additional handle (20) are associated with a catch (42) in the casing (15),
    the catch (42), when the leaf (39) is in the closed position and abuts the fixed frame (2), is held by an abutment (41) on the fixed frame side against the restoring action of an energy accumulator (47), e.g. a spring,
    when the leaf (3) is lifted off the fixed frame (2), the catch (42) is prestressed against the additional bolt (18) by action of the energy accumulator (47), and
    the additional bolt (18) can be locked in its disengaged position (Fig. 1) by the catch (42).
  4. A mechanism according to any of claims 1 to 3, characterised in that the additional bolt (18) is a hooked bolt pivotable around a stationary axis (19 - 19) in the casing (15) and positively coupled to the additional handle (20) by a cam attachment (23), and
    the additional handle (20) bears an eccentric (25) which is operative on the one hand as an actuator for the slide (38) and on the other hand as a blocking attachment for the additional bolt (18) when in the engaged position.
  5. A mechanism according to any of claims 1 to 4, characterised in that
    the cam (26) associated with the rotary drive pin (8) of the operating lever (9) is of use on the one hand as an actuator for the slide (38), when the additional bolt (18) is in its engaged position (Fig. 2), whereas on the other hand it is operative as a catch element for the rotary drive pin (8) of the operating lever (9) as soon as the additional bolt (18) is in the disengaged position (Fig. 1).
  6. A mechanism according to any of claims 1 to 5, characterised in that the catch (42) is a slide (43) guided in the additional bolt casing (15) and on the one hand comes into operative connection with the abutment (41) on the fixed frame side via the end of the slide (43) projecting from the casing, while on the other hand it carries a locking cam (49) which, when the additional bolt (18) is in the disengaged position (Fig. 1), is adapted to be placed under the action of the energy accumulator (47) into the path of motion of a blocking stud (50 on the additional bolt (18).
  7. A mechanism according to any of claims 1 to 6, characterised in that the additional bolt casing (15), on its side formed with an outlet opening (12) for the additional bolt (18) and with an outlet opening (45) for the slide (43) of the catch (42), has an abutment edge (58) projecting over the base surface and serving as an alignment means in operative connection with the longitudinal edge of the leaf cheek (Fig. 4).
