Description

Die Erfindung betrifft eine Bedienungssperre für die verdeckt in einer durch eine Abdeckschiene abgedeckten Falznut angeordneten Betätigungsgestänge an Fenster, Türen oder dgl. mit den Merkmalen des Oberbegriffs des Anspruchs 1, durch die DE-A-33 33 702 bekannt geworden.The invention relates to an operating lock for the operating linkage arranged in a folded groove covered by a cover rail on windows, doors or the like. With the features of the preamble of claim 1, become known from DE-A-33 33 702.

Derartige Bedienungssperren sind in verschiedenen Ausführungsformen bekannt. Bei Betätigungsgestängen, bei denen die einzelnen Stangen in mehrere verschiedene Betriebsstellungen bewegt werden können, z.B. in eine der Schließstellung des Flügels, eine der Kippstellung eines Flügels und eine einer Schwenkstellung des Flügels entsprechende Stellung. Durch die Bedienungssperre soll nun eine falsche Betätigung des Betätigungsgestänges verhindert werden, wenn sich der Flügel in bestimmten Stellungen befindet. Die Bedienungssperren sind zumeist in der Nähe des Handbetätigungselementes oder Getriebes für das Betätigungsgestänge angeordnet, und zwar verdeckt im Falz des Flügels.Such operating locks are known in various embodiments. For actuating linkages in which the individual rods can be moved into several different operating positions, e.g. in one of the closed position of the wing, a position corresponding to the tilting position of a wing and a pivoting position of the wing. The operating lock is now intended to prevent incorrect actuation of the actuating linkage when the wing is in certain positions. The operating locks are usually located in the vicinity of the manual control element or gearbox for the control linkage, concealed in the fold of the wing.

Beispielsweise zeigt die DE-A-34 29 699 einen schwenkbar angeordneten federbelasteten Sperrhebel, der an der Abdeckschiene schwenkbar gelagert ist und in eine entsprechende Ausnehmung der Betätigungsstange hakenförmig eingreifen kann, um diese zu sperren. Die DE-A-33 33 702 zeigt ein hohlzylindrisches mit seiner Achse parallel zur Abdeckschiene angeordnetes Federelement, das in einer besonderen schalenförmigen Montageplatte gehalten ist, und ein stößelförmiges Sperrglied senkrecht zur Ebene der Abdeckschiene in eine Sperrstellung unterstützt. Das Sperrglied weist einen inneren verbreiterten Sperrkopf auf, der bei Entlastung der Feder von unten in eine Ausnehmung der Betätigungsstange greift und bei Auflaufen der Feder auf einen Auflaufabschnitt des anderen Rahmenelementes unter die Ebene der Betätigungsstange gedrückt wird, so daß diese verschoben werden kann, wobei der Schaft des Sperrgliedes in einem Längsschlitz der Betätigungsstange gleitet. Die Verankerung erfolgt durch Fußteile, die seitlich klammernd in Öffnungen eingreifen, die in Abdeckschienen-Richtung von der Sperrglied-Öffnung beabstandet sind. Weitere Ausführungen für eine Bedienungssperre sind in der DE-A-33 35 306 gezeigt. Bei dem ersten Ausführungsbeispiel liegt auf der Oberseite der Abdeckschiene als Sperrfeder eine brückenförmig gewölbte Blattfeder, die in entsprechenden Öffnungen der Abdeckschiene mit ihren Enden verankert ist. Die Blattfeder trägt das Sperrelement, wobei die Verbindung zwischen Bedienungssperre und Abdeckschiene wiederum durch einen bajonettartigen Verschluß erfolgt, zu dessen Verriegelung ein besonderes Schwenkglied notwendig ist.For example, DE-A-34 29 699 shows a pivotably arranged spring-loaded locking lever which is pivotably mounted on the cover rail and can engage in a hook-shaped manner in a corresponding recess in the actuating rod in order to lock it. DE-A-33 33 702 shows a hollow cylindrical spring element with its axis parallel to the cover rail, which is held in a special bowl-shaped mounting plate and supports a plunger-shaped locking member perpendicular to the plane of the cover rail in a locking position. The locking member has an inner widened locking head which engages in a recess of the actuating rod when the spring is relieved and is pressed when the spring comes onto an overrun portion of the other frame element below the level of the actuating rod so that it can be moved, the Shaft of the locking member slides in a longitudinal slot in the actuating rod. The anchoring is carried out by foot parts which engage laterally with clamps in openings which are spaced from the locking member opening in the direction of the cover rails. Further designs for an operating lock are shown in DE-A-33 35 306. In the first embodiment, a bridge-shaped arched leaf spring is located on the top of the cover rail as a locking spring, which with its in corresponding openings of the cover rail Ends is anchored. The leaf spring carries the locking element, the connection between the operating lock and the cover rail in turn being made by a bayonet-type lock, for the locking of which a special pivot member is necessary.

Es ist Aufgabe der Erfindung, eine Bedienungssperre mit den Merkmalen des Oberbegriffs des Anspruchs 1 so weiterzubilden, daß deren Herstellung weniger aufwendig wird und ihre Montage ohne Beeinträchtigung der Funktionsweise vereinfacht wird.It is an object of the invention to further develop an operating lock with the features of the preamble of claim 1 in such a way that its production becomes less complex and its assembly is simplified without impairing the functioning.

Diese Aufgabe wird durch die Lehre des Anspruchs 1 gelöst.This object is achieved by the teaching of claim 1.

Mit einer einzigen Schwenkbewegung in einer senkrechten Längsmittelebene lassen sich der hakenförmig vergrößerter Endabschnitt und das Sperrglied selbst in eine angepaßte profilierte Längsöffnung der Abdeckschiene einfädeln, was nur möglich ist unter gleichzeitiger elastischer Verformung der Blattfeder, die nach Eintreten des Endabschnittes durch die Öffnung automatisch für die senkrechte Ausrichtung des Sperrgliedes und für dessen zuverlässige Verankerung an der Abdeckschiene sorgt, da im Montagezustand oder in der Einbaustellung der vergrößerte Endabschnitt unter der Abdeckschiene zu liegen kommt. Da seine Abmessungen in Längsrichtung der Schiene größer als die Abmessungen in der gleichen Richtung der Öffnung in der Abdeckschiene ist, kann sich die Bedienungssperre nicht mehr von der Abdeckschiene lösen, es sei denn sie wird wieder entgegen der Wirkung der Feder in eine gegenüber der Abdeckschiene gekippte Stellung gebracht, in der sie leicht aus der Öffnung ausgefädelt werden kann.With a single swivel movement in a vertical longitudinal center plane, the hook-shaped enlarged end section and the locking member itself can be threaded into an adapted profiled longitudinal opening of the cover rail, which is only possible with simultaneous elastic deformation of the leaf spring, which automatically occurs for the vertical after the end section has entered through the opening Alignment of the locking member and for its reliable anchoring on the cover rail ensures that the enlarged end portion comes to rest under the cover rail in the assembled state or in the installed position. Since its dimensions in the longitudinal direction of the rail are larger than the dimensions in the same direction of the opening in the cover rail, the operating lock can no longer be released from the cover rail, unless it is tilted back against the action of the spring into a cover rail that is opposite the cover rail Positioned in which it can be easily threaded out of the opening.

In der bevorzugten Ausführungsform steht die Bedienungssperre, abgesehen von den üblichen Öffnungen in Abdeckschiene und Betätigungsstange aus der Blattfeder, deren höchster Punkt bleibend mit dem als Flachstangenabschnitt ausgebildeten Sperrglied verbunden ist. Durch das flache Stangenprofil ist es lediglich erforderlich, auch in der Abdeckschiene eine entsprechend rechteckförmige Öffnung vorzusehen, die ihrer Form und Größe nach an den Querschnitt des Flachstangenabschnittes angepaßt ist, wobei der Flachstangenabschnitt am Ende einen hakenförmig vergrößerten Abschnitt aufweist. An diesem kann wenigstens einseitig ein seitlicher Ansatz vorgesehen sein, der zur Sperrung mit entsprechenden seitlichen Ausnehmungen eines Längsschlitzes in der Betätigungsstange zusammenwirkt. Zum besseren Aufgleiten auf einen am Blendrahmen ausgebildeten Auflaufabschnitt kann die Blattfeder noch mit einem gesondert hergestellten oder direkt angeformten Betätigungsteil versehen sein.In the preferred embodiment, the operating lock, apart from the usual openings in the cover rail and actuating rod, is made of the leaf spring, the highest point of which is permanently connected to the locking member designed as a flat rod section. Due to the flat bar profile, it is only necessary to provide a correspondingly rectangular opening in the cover rail, which is adapted in shape and size to the cross section of the flat bar section, the flat bar section having a hook-shaped enlarged section at the end. A lateral extension can be provided on this, at least on one side, for locking with corresponding lateral extensions Recesses of a longitudinal slot in the actuating rod cooperates. For better sliding on a run-on section formed on the frame, the leaf spring can also be provided with a separately manufactured or directly molded actuating part.

Die Erfindung wird nachfolgend anhand schematischer Zeichnungen an einem Ausführungsbeispiel näher erläutert.The invention is explained in more detail below with the aid of schematic drawings using an exemplary embodiment.

Es wird auf Figuren 1 und 2 bezug genommen.Reference is made to Figures 1 and 2.

Das nicht näher gezeigte Betätigungsgestänge mit Betätigungsgetriebe weist wenigstens eine durch die Bedienungssperre z.B. in zwei von drei möglichen Stellungen verriegelbare Betätigungsstange 1 auf. Im Bereich der Bedienungssperre weist die Betätigungsstange einen Längsschlitz 4 auf, dessen Länge die drei möglichen Stellungen der Stange umfaßt. In zwei Stellungen von den drei möglichen Stellungen weist der Längsschlitz 4 einseitig oder wie dargestellt beidseitig Randausnehmungen 5, 6 auf.The actuating linkage with actuating gear (not shown in detail) has at least one actuating rod 1 which can be locked by the operating lock, for example in two of three possible positions. In the area of the operating lock, the actuating rod has a longitudinal slot 4, the length of which comprises the three possible positions of the rod. In two positions of the three possible positions, the longitudinal slot 4 has edge recesses 5, 6 on one side or, as shown, on both sides.

Die Betätigungsstange ist in der Regel verdeckt in einer Profilnut z.B. des Flügelrahmens angeordnet. In Figur 2 ist ein Holzrahmenprofil wiedergegeben, bei dem der Flügel 26 im Bereich des Falzes eine übliche und genormte umlaufende Falznut 28 aufweist, in der die Betätigungsstange 1 verdeckt angeordnet ist. Die Falznut 28 ist üblicherweise durch eine Abdeckschiene 2 abgedeckt. Im Bereich der Bedienungssperre weist die Abdeckschiene eine der Form und den Abmessungen nach in vorbestimmter Weise ausgebildete Längsöffnung 7 auf, die im dargestellten Beispiel aus einer rechteckförmigen Öffnung 7 besteht, in der den Randausnehmungen 5 und 6 der Betätigungsstange 1 entsprechende Randausnehmungen 8 vorgesehen sind.The actuating rod is usually covered in a profile groove e.g. arranged of the casement. FIG. 2 shows a wooden frame profile in which the wing 26 has a customary and standardized circumferential groove 28 in the area of the fold, in which the actuating rod 1 is concealed. The fold groove 28 is usually covered by a cover rail 2. In the area of the operating lock, the cover rail has a longitudinal opening 7 designed in a predetermined manner in terms of shape and dimensions, which in the example shown consists of a rectangular opening 7 in which edge recesses 5 and 6 of the actuating rod 1 are provided with corresponding edge recesses 8.

Die Bedienungssperre 3 weist eine bügelförmige Blattfeder 9 auf, deren Enden 10,11 zwecks leichteren Gleitens auf der Oberfläche der Abdeckschiene 2 leicht abgewinkelt sind. Mit dem Bügelscheitel ist starr verbunden ein Sperrglied 14, das in der bevorzugten und dargestellten Ausführungsform aus einem Flachstangenabschnitt besteht, der den Schaft 15 des Sperrgliedes bildet. Die Querschnittsform und die Längsabmessung 20 der Öffnung 7 in der Abdeckschiene 2 ist ziemlich genau an die Querschnittsform unf Abmessungen des Schaftabschnittes 15 des Sperrgliedes angepaßt, so daß der Schaft 15 leichtgängig aber mit geringem Spiel in der Öffnung 7 aufgenommen werden kann.The operating lock 3 has a bow-shaped leaf spring 9, the ends 10, 11 of which are slightly angled for easier sliding on the surface of the cover rail 2. A locking member 14, which in the preferred and illustrated embodiment consists of a flat rod section, which forms the shaft 15 of the locking member, is rigidly connected to the temple apex. The cross-sectional shape and the longitudinal dimension 20 of the opening 7 in the cover rail 2 is adapted almost exactly to the cross-sectional shape and dimensions of the shaft portion 15 of the locking member, so that the shaft 15 can be accommodated in the opening 7 smoothly but with little play.

An den Schaftabschnitt 15 schließt sich ein einseitig verbreiterter hakenförmiger Abschnitt 16 an, der wenigstens auf einer Seite einen Sperrvorsprung 17 aufweist. Der in der Einbaustellung in Längsrichtung der Abdeckschiene und der Öffnung 7 orientierte hakenförmige Abschnitt 16 weist einen Länge 19 (Fig. 3) auf, die größer ist als die Querschnittslänge des Schaftabschnittes 15, die wiederum übereinstimmt mit der Länge 20 der Ausnehmung 7 in der Abdeckschiene.The shaft section 15 is followed by a hook-shaped section 16 which is widened on one side and has a locking projection 17 on at least one side. The hook-shaped section 16 oriented in the longitudinal position of the cover rail and the opening 7 has a length 19 (FIG. 3) which is greater than the cross-sectional length of the shaft section 15, which in turn corresponds to the length 20 of the recess 7 in the cover rail .

Es ist ersichtlich, daß aufgrund dieser Ausbildung und Abmessungen das Sperrglied in die Öffnung 7 nur eingeführt werden kann, wenn das Sperrglied 14 gegenüber der Oberflächenebene der Abdeckschiene 2 unter gleichzeitiger elastischer Verformung der Blattfeder 9 gekippt wird. In dieser Stellung kann der hakenförmige Endabschnitt 16 des Sperrgliedes durch die Öffnung 7 gefädelt werden, bis er unter die Unterseite der Abdeckschiene 2 greift. In diesem Moment richtet die Vorspannung in der Feder 9 das Sperrglied in die normale Stellung senkrecht zur Oberfläche der Abdeckschiene aus und die Bedienungssperre ist an der Abdeckschiene 2 zuverlässig und unverlierbar verankert. Bei geöffnetem Flügel hält die Blattfeder das Sperrglied in einer Stellung, in der der hakenförmige Abschnitt an der Unterseite der Abdeckschiene 2 anliegt. Der seitliche Ansatz 17 ist in Bezug auf den hakenförmigen Abschnitt 16 so angeordnet, daß er in dieser Stellung in eine seitliche Ausnehmung 5 oder 6 der Betätigungsstange 1 eingreift, wie dies Figur 4 zeigt. Die Betätigungsstange ist somit gesperrt. Zur Freigabe dieser Stange wird das Sperrglied nach innen gedrückt, wie dies Figur 5 zeigt, so daß der Ansatz 17 aus der Ausnehmung 5 oder 6 freikommt, worauf die Betätigungsstange verschoben werden kann. Bei Erreichen einer der zu sperrenden Stellungen rastet der Sperransatz 17 automatisch in die Sperrausnehmungen 5 oder 6 ein.It can be seen that due to this design and dimensions, the locking member can only be inserted into the opening 7 if the locking member 14 is tilted with respect to the surface plane of the cover rail 2 with simultaneous elastic deformation of the leaf spring 9. In this position, the hook-shaped end section 16 of the locking member can be threaded through the opening 7 until it engages under the underside of the cover rail 2. At this moment the preload aligns in the Spring 9 the locking member in the normal position perpendicular to the surface of the cover rail and the operating lock is anchored reliably and captively on the cover rail 2. When the wing is open, the leaf spring holds the locking member in a position in which the hook-shaped section rests on the underside of the cover rail 2. The lateral extension 17 is arranged with respect to the hook-shaped section 16 so that in this position it engages in a lateral recess 5 or 6 of the actuating rod 1, as shown in FIG. 4. The actuating rod is thus locked. To release this rod, the locking member is pressed inwards, as shown in FIG. 5, so that the projection 17 is released from the recess 5 or 6, whereupon the actuating rod can be moved. When one of the positions to be locked is reached, the locking projection 17 automatically engages in the locking recesses 5 or 6.

Zur leichteren Betätigung weist die Blattfeder an ihrem Scheitel ein gesondertes oder unmittelbar angeformtes Betätigungsglied 12 mit einer Betätigungsschräge 13 auf. Diese wirkt, wie Figur 2 zeigt, mit einem Auflaufabschnitt 27 des Blendrahmens 25 zusammen, um beim Schließen des Flügels die Bedienungssperre in die Freigabestellung zu bewegen. Wird der Flügel geöffnet, versucht die Feder automatisch die Bedienungssperre in die Sperrstellung zu bewegen, die wirksam wird, wenn eine den Randausnehmungen 5 oder 6 zugeordnete Stellung des Betätigungsgestänges erreicht ist.For easier actuation, the leaf spring has a separate or directly integrally formed actuating member 12 with an actuating slope 13 at its apex. As FIG. 2 shows, this interacts with an overrun section 27 of the frame 25 in order to move the operating lock into the release position when the sash is closed. If the wing is opened, the spring automatically tries to move the operating lock into the locked position, which takes effect when a position of the actuating linkage assigned to the edge recesses 5 or 6 is reached.

Es ist ersichtlich, daß die Bedienungssperre an der Abdeckschiene 2 auch nach Drehung um 180° eingebaut werden kann.It can be seen that the operating lock on the cover rail 2 can also be installed after rotation by 180 °.
