Description

Die Erfindung betrifft eine Fehlbedienungssperre für Treibstangenbeschläge mit in mehrere Schaltstellungen verschiebbaren Treibstangen, insbesondere für Drehkippbeschläge, bestehend aus einem parallel zur Flügelebene verschwenkbar am Flügel gelagerten Hebel, der einen Sperrnocken od. dgl. trägt, dem mindestens eine Sperrast an der Treibstange zugeordnet ist, in die der Sperrnocken od. dgl. bei einer vorbestimmten Schaltstellung der Treibstange sowie bei geöffnetem Flügel durch einen am Hebel angreifenden Kraftspeicher, z.B. eine Feder, einrückbar ist, während in der Schließlage des Flügel der Hebel entgegen der Wirkung des Kraftspeichers durch einen rahmenseitigen Anschlag verstellbar und sein Sperrnocken od. dgl. aus der Sperrast der Treibstange ausrückbar ist, wobei durch das DE-GM 8 404 724 ist bereits eine Fehlbedienungssperre dieser Art bekannt, der Hebel als zweiarmiger Hebel ausgebildet, dessen einer Hebelarm das Betätigungselement bildet, während der andere Hebelarm an seiner Unterseite den Sperrnocken od. dgl. trägt, bei der die Lagerung des zweiarmigen Hebels aus einem Haken besteht, der in einen Schlitz eines am Flügel sitzenden Trägers lösbar eingerückt ist. Die Einrückstellung des Hakens wird dabei durch eine von ihm abgewendete Kante des Sperrnockens od. dgl. gesichert, welche vor das ihr benachbarte Ende des Schlitzes im Träger greift, während ein Druckstück am freien Ende des zweiarmigen Hebels mit seiner Unterseite ein den Schwenkwinkel des zweiarmigen Hebels relativ zum Träger begrenzendes Anschlagglied bildet. Der Kraftspeicher der Fehlbedienungssperre wird von einer Blattfeder gebildet und auch der das Druckstück tragende bzw. das Betätigungselement bildende Hebelarm des zweiarmigen Hebels ist als Blattfeder ausgelegt, die zu ihrer Verformung einen höheren Kraftaufwand erfordert, als die den Kraftspeicher bildende Blattfeder.The invention relates to a maloperation lock for espagnolette fittings with espagnolette that can be shifted into several switch positions, in particular for tilt-turn fittings, consisting of a lever pivotably mounted on the wing parallel to the wing plane, which carries a locking cam or the like, to which at least one locking latch on the driving rod is assigned that of the locking cams or the like. With a predetermined switching position of the drive rod and with the sash open by an energy accumulator acting on the lever, eg a spring can be engaged, while in the closed position of the wing the lever can be adjusted against the action of the energy accumulator by means of a frame-side stop and its locking cam or the like can be disengaged from the locking catch of the drive rod, whereby DE-GM 8 404 724 already has a mishandling device of this type is known, the lever is designed as a two-armed lever, one lever arm of which forms the actuating element, while the other lever arm carries the locking cam or the like on its underside, in which the bearing of the two-armed lever consists of a hook consisting of a hook Slot of a carrier sitting on the wing is releasably indented. The engagement of the hook is secured by an edge of the locking cam or the like which faces away from it and which engages in front of the end of the slot in the carrier which is adjacent to it, while a pressure piece at the free end of the two-armed lever has the underside of the pivoting angle of the two-armed lever forms relative to the support stop member. The energy accumulator of the maloperation lock is formed by a leaf spring and the lever arm of the two-armed lever which carries the pressure piece or forms the actuating element is designed as a leaf spring, which requires a greater effort to deform than the leaf spring forming the energy accumulator.

Der Vorteil dieser bekannten Fehlbedienungssperre liegt darin, daß sie bei einfacher Ausbildung eine unkomplizierte Zuordnung zu einer Treibstange des Treibstangenbeschlages - auch nachträglich noch - ermöglicht und dabei funktionssicher arbeitet. Vorteilhaft ist aber auch, daß die Fehlbedienungssperre eine Auslegung hat, mit der problemlos beträchtliche Stellwegdifferenzen überbrückt werden können, die sich aus unterschiedlichen Abständen zwischen den Falzumfangsflächen zwischen Flügel und Rahmen ergeben.The advantage of this known maloperation lock is that, with a simple design, it enables uncomplicated assignment to a drive rod of the drive rod fitting - even subsequently - and functions reliably. But it is also advantageous that the maloperation lock has a design with which considerable travel differences can easily be bridged, which result from different distances between the fold peripheral surfaces between the sash and frame.

Eine einfache Schnapp-Rastverbindung macht es - auch dem Laien - möglich, die bekannte Fehlbedienungssperre an einem bereits funktionsgerecht eingebauten Treibstangenbeschlag anzubringen.A simple snap-in locking connection makes it possible - even for the layperson - to attach the well-known misuse lock to an espagnolette fitting that is already installed in a functional manner.

Die Erfindung zielt nun darauf ab, an einer Fehlbedienungssperre der durch das DE-GM 8 404 724 bekannt gewordenen Art die auf der Außenseite des Trägers, insbesondere der Stulpschiene eines Treibstangenbeschlages, liegenden Funktionsteile gegen Beschädigung und Verschmutzung geschützt anzuordnen.The invention is now aimed at a malfunction lock of the type made known by DE-GM 8 404 724 to arrange the functional parts lying on the outside of the carrier, in particular the faceplate of an espagnolette fitting, protected against damage and soiling.

Gelöst wird diese Aufgabe nach dem Kennzeichen des Anspruchs 1 dadurch, daß der zweiarmige Hebel bis zu seinem das Druckstück tragenden bzw. das Betätigungselement bildenden Endbereich von einer Kappe umfaßt ist, die mit ihren Rändern auf dem Träger, z.B. der Stulpschiene, aufliegt, daß diese Kappe an ihrer Unterseite einen Hakenansatz aufweist, der in einen Schlitz des Trägers einrückbar ist, und daß die Kappe bereichsweise im Anschluß an ihre Ränder mit einer Wand oder einem Steg versehen ist, die bzw. der eine Stützauflage für den freien Schenkel der als Kraftspeicher vorgesehenen Blattfeder bildet.This object is achieved according to the characterizing part of claim 1 in that the two-armed lever is covered up to its end region which carries the pressure piece or forms the actuating element by a cap which has its edges on the carrier, e.g. the faceplate, rests that this cap has on its underside a hook extension which can be inserted into a slot of the carrier, and that the cap is provided in regions following its edges with a wall or a web, which or a support pad for forms the free leg of the leaf spring provided as an energy store.

Diese Ausgestaltung hat den Vorteil, daß eine weitestgehende Verkapselung der beweglichen Funktionsteile der Fehlbedienungssperre erreicht wird und diese Verkapselung sich ebensoleicht und sicher durch eine Schnapp-Rastverbindung am Träger anbringen läßt, wie die Fehlbedienungssperre selbst.This configuration has the advantage that a largely encapsulation of the movable functional parts of the maloperation lock is achieved and this encapsulation can be attached to the carrier just as easily and safely by means of a snap-lock connection as the maloperation lock itself.

Ein weiterbildendes Erfindungsmerkmal wird nach Anspruch 2 darin gesehen, daß die Wand oder der Steg der Kapsel an ihrem bzw. seinem auswärts gerichteten Ende einen nach oben vorspringenden Anschlag trägt, der ein Widerlager für das freie Ende der Blattfeder bildet, und daß das gegenüberliegende Ende der Kappe eine geneigte Gleitbahn hat, an der die rückwärtige Flanke des Sperrnockens entlangbewegbar ist. Es hat sich gezeigt, daß durch diese Maßnahmen unter Vermittlung der Fehlbedienungssperre eine optimale Lagensicherung der Kappe am Träger erreicht wird.A further inventive feature is seen in claim 2 in that the wall or the web of the capsule carries at its or its outward end an upwardly projecting stop which forms an abutment for the free end of the leaf spring, and that the opposite end of the Cap has an inclined slideway along which the rear flank of the locking cam can be moved. It has been shown that by means of these measures, by means of the maloperation lock, an optimal position securing of the cap on the carrier is achieved.

Nach Anspruch 3 wird ein anderes Ausgestaltungsmerkmal der Erfindung auch darin gesehen, daß die Kappe in ihrer Deckwand einen Durchlaß für das Druckstück und/oder den dieses tragenden Arm des zweiarmigen Hebels aufweist, der sich über die Länge der Wand oder des Steges erstreckt, aber mit Abstand oberhalb desselben liegt.According to claim 3, another embodiment of the invention is also seen in that the cap in its top wall has a passage for the pressure piece and / or the arm of the two-armed lever carrying this, which extends over the length of the wall or the web, but with Distance above it.

Nach Anspruch 4 enthält die Wand oder der Steg einen vom freien Ende ausgehenden Schlitz, den der den Sperrnocken tragende Längssteg der Fehlbedienungssperre führend durchgreift.According to claim 4, the wall or the web contains a slot extending from the free end, which the longitudinal web of the misuse lock carrying the locking cam engages through.

Eine gegenseitige Ausrichtung der Kappe und der Fehlbedienungssperre relativ zum Träger wird durch die Merkmale der Ansprüche 3 und 4 auf einfache Art und Weise erreicht.A mutual alignment of the cap and the misuse lock relative to the carrier is achieved in a simple manner by the features of claims 3 and 4.

Es ist nach Anspruch 5 weiterhin vorgeschlagen, daß die Kappe von einem einstückigen Formteil aus Metall-Druckguß oder Kunststoff-Spritzguß gebildet wird.It is further proposed according to claim 5 that the cap is formed from a one-piece molded part made of die-cast metal or plastic injection molding.

Vorteilhaft für einen wahlweisen Rechts- und Linksanschlag ein und desselben Treibstangenbeschlages ist es auch, wenn gemäß Anspruch 6 die Kappe und das den Durchlaß in deren Deckwand durchgreifende Druckstück zu einer Normalebene des Trägers symmetrisch gestaltet sind. Schließlich liegt es auch noch im Rahmen der Erfindung, daß nach Anspruch 7 im Träger der Eingriffsschlitz für den Hakenansatz der Kappe dem Durchgriffsschlitz für den den Sperrnocken und den Hakenansatz tragenden Längssteg des zweiarmigen Hebels mit Abstand vorgelagert ist.It is also advantageous for an optional right and left stop of one and the same drive rod fitting if, according to claim 6, the cap and the pressure piece penetrating the passage in the top wall thereof are designed symmetrically to a normal plane of the carrier. Finally, it is also within the scope of the invention that, according to claim 7, the engagement slot for the hook extension of the cap is arranged in front of the access slot for the longitudinal web of the two-armed lever carrying the locking cam and the hook extension.

In der Zeichnung ist der Gegenstand der Erfindung als Ausführungsbeispiel dargestellt. Dabei zeigt

The drive rod 2 is guided longitudinally relative to the faceplate 1 and can be moved into several, for example three, different sliding positions, each of which corresponds to a very specific switching position of the drive rod fitting 3. In the case of an espagnolette fitting 3, which is used, for example, to actuate a tilt-and-turn window or a tilt-and-turn door, the first switching position preferably corresponds to the locking position for the wing, the second switching position is assigned to the rotary opening function for the wing, while the third switching position determines the tilt opening function for the wing.

In vielen Fällen ist es erwünscht oder sogar Bedingung, mindestens eine der beiden die Offnungsfunktion des Flügels bestimmenden Schaltstellungen der Treibstange 2, bei Drehkippfenstern oder -türen regelmäßig die der Drehöffnungsfunktion zugeordnete Schaltstellung, selbsttätig zu blockieren, sobald der Flügel aus seiner Schließlage in Öffnungsrichtung bewegt wird. Andererseits muß diese Blockierung - ebenfalls selbsttätig - wieder aufgehoben werden, sobald der Flügel aus der Öffnungsstellung in seine Schließstellung zum feststehenden Rahmen übergeführt wird. Diesem Zweck dient eine Fehlbedienungssperre 4. Als Träger für diese Fehlbedienungssperre 4 wird die Stulpschiene 1 des Treibstangenbeschlages 3 benutzt.In many cases, it is desirable or even a requirement to automatically block at least one of the two switching positions of the drive rod 2 that determine the opening function of the leaf, and, in the case of turn-tilt windows or doors, the switching position assigned to the rotating opening function, as soon as the leaf is moved from its closed position in the opening direction . On the other hand, this blocking - also automatically - must be lifted again as soon as the sash is moved from the open position into its closed position to the fixed frame. A misuse lock 4 serves this purpose. The faceplate 1 of the drive rod fitting 3 is used as a carrier for this misuse lock 4.

Die Fehlbedienungssperre 4 besteht aus einem parallel zur Flügelebene verschwenkbar an der Stulpschiene 1 gelagerten, zweiarmigen Hebel 5, dessen einer Hebelarm 6 das mit dem feststehenden Rahmen zusammenwirkende Betätigungselement bildet, während sein anderer Hebelarm 7 an seiner Unterseite, und zwar in Verlängerung eines schmalen Längssteges 8, einen Sperrnocken 9 od. dgl. trägt, dem mindestens eine Sperrast 10 in der Treibstange 2 zugeordnet ist.The maloperation lock 4 consists of a two-armed lever 5, which is pivotably mounted on the faceplate 1 parallel to the sash plane, one lever arm 6 of which forms the actuating element interacting with the fixed frame, while its other lever arm 7 on its underside, namely as an extension of a narrow longitudinal web 8 , carries a locking cam 9 or the like, which is assigned at least one locking catch 10 in the drive rod 2.

Mit seinem Längssteg 8 durchgreift der Hebelarm 7 des zweiarmigen Hebels 5 einen schmalen Längsschlitz 11, der vorzugsweise auf der Längsmittellinie der Stulpschiene 1 angeordnet ist.With its longitudinal web 8, the lever arm 7 of the two-armed lever 5 passes through a narrow longitudinal slot 11, which is preferably arranged on the longitudinal center line of the faceplate 1.

An seinem dem Hebelarm 6 des zweiarmigen Hebels 5 unmittelbar benachbarten Ende ist der Längssteg 8 des Hebelarms 7 mit einer in Richtung des Hebelarms 6 vorspringenden Hakennase 12 versehen, welche durch den Längsschlitz 11 mit der Rückseite der Stulpschiene 1 in Stütz- und Halteeingriff gebracht werden kann. Die Hakennase 12 dient dabei zugleich als Schwenklager für den zweiarmigen Hebel 5 an der Stulpschiene 1.At its end immediately adjacent to the lever arm 6 of the two-armed lever 5, the longitudinal web 8 of the lever arm 7 is provided with a hook nose 12 projecting in the direction of the lever arm 6, which can be brought into support and holding engagement through the longitudinal slot 11 with the rear side of the faceplate 1 . The hook nose 12 also serves as a pivot bearing for the two-armed lever 5 on the faceplate 1.

Die aus den Fig. 1 und 2 ersichtliche Einrückstellung der Hakennase 12 wird durch die von ihr abgewendete Kante 13 des Sperrnockens 9 od. dgl. im Zusammenwirken mit dem dieser benachbarten Ende 14 des Längsschlitzes 11 gesichert, und zwar dadurch, daß der Schwenkwinkel des zweiarmigen Hebels 55 relativ zur Stulpschiene 1 durch einen Anschlag 15 begrenzt wird, wie das deutlich die Fig. 2 erkennen läßt.1 and 2, the engagement of the hook nose 12 is secured by the edge 13 of the locking cam 9 or the like facing away from it in cooperation with the adjacent end 14 of the longitudinal slot 11, namely in that the pivoting angle of the two-armed Lever 55 is limited relative to the faceplate 1 by a stop 15, as can be clearly seen in FIG. 2.

An der Unterseite des den Längssteg 8 mit dem Sperrnocken 8 od. dgl. und der Hakennase 12 tragenden Hebelarms 7 ist als Kraftspeicher eine Blattfeder 16 befestigt, die eine etwa Z-förmig gekröpfte Gestalt mit dem Befestigungsschenkel 16a, dem freien Federschenkel 16b und dem diese miteinander verbindenden Steg 16c aufweist. Der freie Federschenkel 16b ragt dabei in Richtung des das Betätigungselement bildenden Hebelarms 6 über die Hakennase 12 hinaus und stützt sich mit Vorspannung auf der Außenseite der Stulpschiene 1 bzw. einer Wand oder einem Steg 25 ab, die bzw. der an einer Kappe 26 ausgebildet ist, die auf der Außenseite der Stulpschiene 1 aufliegt.On the underside of the lever arm 7 carrying the longitudinal web 8 with the locking cam 8 or the like and the hook nose 12, a leaf spring 16 is fastened as an energy store, which has an approximately Z-shaped shape with the fastening leg 16a, the free spring leg 16b and the latter has connecting web 16c. The free spring leg 16b protrudes in the direction of the lever arm 6 forming the actuating element beyond the hook nose 12 and is supported with prestress on the outside of the faceplate 1 or a wall or a web 25 which is formed on a cap 26 , which rests on the outside of the faceplate 1.

Die Blattfeder 16 sucht den zweiarmigen Hebel 5 der Fehlbedienungssperre 4 in der aus Fig. 1 ersichtlichen Lage zu halten. Durch die Wirkung der Blattfeder 6 wird dabei der Sperrnocken 9 od. dgl. an der Unterseite des Hebelarms 7 mit der Sperrast 10 der Treibstange 2 selbsttätig in Eingriff gebracht und gehalten, sobald durch entsprechende Verschiebung der Treibstange 2 deren Sperrast 10 in den Wirkbereich des Sperrnockens 9 od. dgl. gelangt ist und der Flügel relativ zum feststehenden Rahmen in eine öffnungsstellung bewegt wird. Durch die Fehlbedienungssperre 4 wird daher die Treibstange 2 relativ zur Stulpschiene 1 selbsttätig gegen unerwünschtes Verschieben blockiert.The leaf spring 16 seeks to hold the two-armed lever 5 of the malfunction lock 4 in the position shown in FIG. 1. Due to the action of the leaf spring 6, the locking cam 9 or the like is automatically engaged and held on the underside of the lever arm 7 with the locking latch 10 of the drive rod 2 as soon as the locking bar 10 is moved into the effective range of the locking cam by a corresponding displacement of the drive rod 2 9 or the like. Has come and the wing is moved relative to the fixed frame in an open position. Due to the mishandling device 4, the drive rod 2 is automatically blocked relative to the faceplate 1 against undesired displacement.

Wird der Flügel des Fensters oder Tür relativ zum feststehenden Rahmen in Schließstellung bewegt, dann läuft die Fehlbedienungssperre 4 mit dem als Betätigungsglied dienenden Hebelarms 6 des zweiarmigen Hebels 5 gegen einen rahmenseitigen Anschlag an und wird dabei entgegen der Wirkung der Blattfeder 16 aus der in Fig. 1 gezeigten Sperrstellung in die aus Fig. 2 ersichtliche Freigabestellung verschwenkt, und zwar um die die Stulpschiene 1 am einen Ende des Längsschlitzes 11 untergreifende Hakennase 12. Hierdurch gelangt dann der Sperrnocken 9 od. dgl. aus der Sperrast 10 in der Treibstange 2 und gibt diese für eine Längsverschiebung relativ zur Stulpschiene 1 frei, die durch ein Betätigungsgetriebe bewirkt werden kann.If the sash of the window or door is moved relative to the fixed frame in the closed position, then the maloperation lock 4 runs with the lever arm 6 serving as the actuating element of the two-armed lever 5 against a frame-side stop and is thereby counteracted by the action of the leaf spring 16 from the one in FIG. 1 pivoted into the release position shown in FIG. 2 pivoted, namely around the hook nose 12 engaging under the faceplate 1 at one end of the longitudinal slot 11. As a result, the locking cam 9 or the like then comes out of the locking catch 10 in the drive rod 2 and gives this free for a longitudinal displacement relative to the faceplate 1, which can be effected by an actuating gear.

Auf der Oberseite des zweiarmigen Hebels 5 ist eine Blattfeder 17 mit ihrem einen Ende befestigt, beispielsweise vernietet. Ihr anderes Ende ragt über den das Betätigungselement bildenden Hebelarm 6 um ein beträchtliches Maß hinaus, wie dies deutlich der Zeichnung entnommen werden kann. Der den Hebelarm 6 überragende Längenabschnitt der Blattfeder 17 trägt an seinem freien Ende ein Druckstück 18, welches als Auflauffläche mit dem am feststehenden Rahmen angeordneten oder hiervon gebildeten Betätigungsanschlag zusammenwirkt.On the top of the two-armed lever 5, a leaf spring 17 is attached at one end, for example riveted. Its other end extends beyond the lever arm 6 forming the actuating element to a considerable extent, as can be clearly seen in the drawing. The longitudinal section of the leaf spring 17 projecting beyond the lever arm 6 carries at its free end a pressure piece 18 which acts as a run-up surface with the on the fixed frame arranged or formed actuating stop cooperates.

Damit sich das Druckstück 18 lösbar auf das freie Ende der Blattfeder 17 aufstecken läßt, ist es mit einer eingeformten Führung 19 versehen, die beispielsweise eine nach unten offene T-Querschnittsform aufweisen kann.So that the pressure piece 18 can be detachably attached to the free end of the leaf spring 17, it is provided with a molded-in guide 19, which can have, for example, a T-shaped cross-section that is open at the bottom.

Das Druckstück 18 hat an seinem dem Hebelarm 6 des zweiarmigen Hebels 5 zugewendeten Ende eine armartige Verlängerung 23, die an ihrer Oberseite einen Rastwulst 20 trägt, welcher entgegen der Rückstellkraft der Blattfeder 17 in eine Rastkerbe 21 an der Unterseite des Hebelarms 16 selbsttätig einrücken kann, wenn das Druckstück 18 mit seiner Führung 19 in Längsrichtung auf die Blattfeder 17 aufgeschoben wird.The pressure piece 18 has at its end facing the lever arm 6 of the two-armed lever 5 an arm-like extension 23, which carries a latching bead 20 on its upper side, which can engage automatically against the restoring force of the leaf spring 17 in a latching notch 21 on the underside of the lever arm 16, when the pressure piece 18 is pushed with its guide 19 in the longitudinal direction onto the leaf spring 17.

Die Eigenelastizität des frei auskragenden Teilstücks der Blattfeder 17 hält dabei nicht nur die Rastwulst 20 des Druckstücks 18 mit der Rastkerbe 21 im Hebelarm 6 in Sicherungseingriff, sondern sie bietet zugleich noch den Vorteil, daß ein und dieselbe Ausführungsform einer Fehlbedienungssperre 4 auch beträchtlich unterschiedliche Abstandsdifferenzen zwischen den Falzumfangsflächen von Flügel und feststehendem Rahmen problemlos überbrücken kann, ohne daß die Funktionsfähigkeit und Funktionssicherheit der Fehlbedienungssperre 4 beeinträchtigt werden.The inherent elasticity of the freely projecting section of the leaf spring 17 not only holds the locking bead 20 of the pressure piece 18 with the locking notch 21 in the lever arm 6 in locking engagement, but it also offers the advantage that one and the same embodiment of a misuse lock 4 also has considerably different distance differences between can easily bridge the rebate circumferential surfaces of the sash and the fixed frame without the operability and functional reliability of the maloperation lock 4 being impaired.

Einer übermäßigen Erhöhung der Vorspannung der Blattfeder 17 kann dabei auf einfache Weise dadurch vorgebeugt werden, daß der das Betätigungselement bildende Hebelarm 6 gegenüber der Unterseite der Blattfeder 17 einen sich zum freien Ende hin etwa keilförmig erweiternden Spalt 22 bildet, wenn sich die Blattfeder 17 in völlig entspanntem Zustand befindet (Fig. 1).An excessive increase in the bias of the leaf spring 17 can be prevented in a simple manner in that the lever arm 6 forming the actuating element forms a wedge-shaped widening gap 22 with respect to the underside of the leaf spring 17 when the leaf spring 17 is completely relaxed state (Fig. 1).

Vorteilhaft ist, daß der Rastwulst 20 mit der Rastkerbe 21 durch die Eigenelastizität der Blattfeder 17 in kippgelenkartigem Eingriff gehalten wird, und zwar in jeder möglichen Funktionsstellung der Fehlbedienungssperre 4, wie das ein Vergleich der Fig. 1 und 2 deutlich macht. Hierdurch wird nämlich auf einfache Art und Weise sichergestellt, daß sich das Druckstück 18 nicht unbeabsichtigt von der Blattfeder 17 lösen kann. In der Ausrückstellung der Fehlbedienungssperre 4 gemäß Fig. 2 wirkt dann nämlich die Unterseite 15 des Druckstücks 18 als Anschlag mit der Oberseite der Stulpschiene 1 bzw. der auf dieser aufliegenden Kappe 26 zusammen und begrenzt dadurch den maximalen Schwenkwinkel für den zweiarmigen Hebel 5.It is advantageous that the locking bead 20 is held with the locking notch 21 by the inherent elasticity of the leaf spring 17 in a tilt-joint-like engagement, in every possible functional position of the misuse lock 4, as is clear from a comparison of FIGS. 1 and 2. This ensures in a simple manner that the pressure piece 18 cannot unintentionally detach from the leaf spring 17. In the disengaged position of the maloperation lock 4 according to FIG. 2, the underside 15 of the pressure piece 18 acts as a stop with the top of the faceplate 1 or the cap 26 resting thereon, thereby limiting the maximum pivoting angle for the two-armed lever 5.

Solange das Druckstück 18 auf der Blattfeder 17 sitzt und mit seiner armartigen Verlängerung 23 den Hebelarm 6 des zweiarmigen Hebels 5 unter greift, kann die Kante 13 des Sperrnockens 9 od. dgl. nicht völlig aus dem Längsschlitz 11 der Stulpschiene 1 herausgehoben werden, sondern verbleibt sperrend vor dem Ende 14 dieses Längsschlitzes 11.As long as the pressure piece 18 sits on the leaf spring 17 and engages the lever arm 6 of the two-armed lever 5 with its arm-like extension 23, the edge 13 of the locking cam 9 or the like cannot be lifted completely out of the longitudinal slot 11 of the faceplate 1, but remains blocking in front of the end 14 of this longitudinal slot 11.

Zum Lösen der Fehlbedienungssperre 4 von der Stulpschiene 1 muß also zunächst das Druckstück 18 entgegen der Wirkung der ineinandergreifenden Rastmittel 20 und 21 von der Blattfeder 17 abgezogen werden, damit sich der das Betätigungselemente bildende Hebelarm 6 des zweiarmigen Hebels 5 genügend weit entgegen der Wirkung der Blattfeder 17 herunterdrücken läßt um die Kante 13 des Sperrnockens 9 od. dgl. völlig aus dem Längsschlitz 11 der Stulpschiene 1 herauszuheben. Erst dann läßt sich nämlich die Hakennase 12 mit der Stulpschiene 1 außer Halteeingriff bringen.To release the maloperation lock 4 from the faceplate 1, the pressure piece 18 must first be pulled against the action of the interlocking latching means 20 and 21 from the leaf spring 17 so that the actuating elements forming the lever arm 6 of the two-armed lever 5 sufficiently far against the action of the leaf spring 17 can be pressed down to completely lift the edge 13 of the locking cam 9 or the like out of the longitudinal slot 11 of the faceplate 1. Only then can the hook nose 12 be brought out of holding engagement with the faceplate 1.

Der den Sperrnocken 9 od. dgl. und die Hakennase 12 einstückig aufweisende Längssteg 8 ist noch mit einem Quersteg 24 versehen, welcher den Befestigungsschenkel 16a der Blattfeder 16, den zweiarmigen Hebel 5 und auch die auf dessen Oberseite anliegende Blattfeder 17 im Bereich von seinem Querschnitt angepaßten Durchbrüchen durchgreift. An der Oberseite der Blattfeder 17 ist dabei der Quersteg 24 durch Vernietung festgelegt. Auf diese Art und Weise läßt sich ein besonders einfacher Zusammenbau der Fehlbedienungssperre 4 erreichen.The locking bar 9 or the like. And the hooked lug 12 in one piece having the longitudinal web 8 is also provided with a cross bar 24, which the fastening leg 16a of the leaf spring 16, the two-armed lever 5 and also the leaf spring 17 resting on its upper side in the region of its cross section adapted breakthroughs. At the top of the leaf spring 17, the cross bar 24 is fixed by riveting. In this way, a particularly simple assembly of the misuse lock 4 can be achieved.

Die auf der Außenseite der Stulpschiene 1 aufliegende Kappe 26 umfaßt den zweiarmigen Hebel 5 bis zu seinem das Druckstück 18 tragenden bzw. das Betätigungselement bildenden Endbereich und schützt dadurch die wesentlichen Funktionsteile der Fehlbedienungssperre 4 gegen Verschmutzung und Beschädigung.The cap 26 resting on the outside of the faceplate 1 comprises the two-armed lever 5 up to its end region which carries the pressure piece 18 or forms the actuating element and thereby protects the essential functional parts of the maloperation lock 4 against dirt and damage.

Wie erkennbar ist, liegt dabei die Kappe 26 mit ihren Rändern 27 auf der Außenseite der Stulpschiene 1 auf.As can be seen, the cap 26 lies with its edges 27 on the outside of the faceplate 1.

Am einen Ende der Kappe 26 schließt sich unmittelbar an deren Ränder 27 die Wand oder der Steg 25 an. An ihrer Unterseite ist dabei ein Hakenansatz 28 ausgebildet, der sich in einen Schlitz 29 der Stulpschiene 1 einrücken läßt, welcher dem Schlitz 11 mit einem gewissen Abstand vorgelagert ist.At one end of the cap 26, the wall or the web 25 directly adjoins its edges 27. On its underside, a hook extension 28 is formed, which can be inserted into a slot 29 of the faceplate 1, which is in front of the slot 11 at a certain distance.

Über den Hakenansatz 28 wird die Kappe 26 in ähnlicher Weise durch eine Schnapp-Rastverbindung an der Stulpschiene 1 fixiert, wie dies auch für den zweiarmigen Hebel 5 mittels der Hakennase 12 innerhalb des Längsschlitzes 11 geschieht. Die Lagenfixierung der Kappe 26 wird dabei über den Federschenkel 16b der Blattfeder 16 bewirkt, weil dieser unter Vorspannung auf der Oberseite der Wand bzw. des Steges 25 aufliegt.Over the hook extension 28, the cap 26 is fixed in a similar manner to the faceplate 1 by a snap-lock connection, as is also the case for the two-armed lever 5 by means of the hook nose 12 within the longitudinal slot 11. The position fixing of the cap 26 is effected via the spring leg 16b of the leaf spring 16 because it rests under prestress on the upper side of the wall or of the web 25.

Damit der Hakenansatz 28 der Kappe 26 nicht unbeabsichtigt aus dem Schlitz 29 der Stulpschiene 1 ausrasten kann, steht von der Wand oder dem Steg 25 ein Anschlag 30 hoch, der mit dem freien Ende am Federschenkel 16b der Blattfeder 16 als Widerlager zusammenwirkt. Solange daher die Kante 13 am Längssteg 8 des zweiarmigen Hebels 5 noch innerhalb des Längsschlitzes 11 vor dessen Endkante 14 liegt, läßt sich also die Kappe 26 nicht verschieben.So that the hook extension 28 of the cap 26 cannot unintentionally disengage from the slot 29 of the faceplate 1, a stop 30 stands up from the wall or the web 25 and cooperates with the free end on the spring leg 16b of the leaf spring 16 as an abutment. Therefore, as long as the edge 13 on the longitudinal web 8 of the two-armed lever 5 is still within the longitudinal slot 11 in front of its end edge 14, the cap 26 cannot be moved.

Wie bereits weiter vorne erwähnt wurde, muß zum Lösen der Fehlbedienungssperre 4 von der Stulpschiene 1 zunächst das Druckstück 18 von der Blattfeder 17 entfernt werden, damit sich der Längssteg 8 am zweiarmigen Hebel 5 so weit hochschwenken läßt, daß die Kante 13 des Sperrnockens 9 völlig aus dem Längsschlitz 11 der Stulpschiene 1 heraustritt. Erst dann läßt sich nämlich die Hakennase 12 aus dem gegenüberliegenden Ende des Längsschlitzes 11 ausklinken. Damit gleichzeitig mit der Hakennase 12 des Längssteges 8 auch der Hakenansatz 28 der Kappe 26 aus dem Längsschlitz 29 der Stulpschiene 1 ausgerückt wird, ist das dem Hakenansatz 28 gegenüberliegende Ende der Kappe 26 innenseitig mit einer geneigten Gleitbahn 31 versehen, auf die die Kante 13 des Sperrnockens 9 od. dgl. einwirkt, sobald sie genügend weit aus dem Längsschlitz 11 ausgetreten ist. Es wird dann die Kappe 26 zwangsweise in Längsrichtung verschoben, so daß ihr Hakenansatz 28 mit dem Längsschlitz 29 außer Eingriff gelangt.As already mentioned above, to release the maloperation lock 4 from the faceplate 1, the pressure piece 18 must first be removed from the leaf spring 17 so that the longitudinal web 8 on the two-armed lever 5 can be swung up so far that the edge 13 of the locking cam 9 completely emerges from the longitudinal slot 11 of the faceplate 1. Only then can the hook nose 12 be released from the opposite end of the longitudinal slot 11. So that at the same time with the hook nose 12 of the longitudinal web 8, the hook extension 28 of the cap 26 is disengaged from the longitudinal slot 29 of the faceplate 1, this is the hook Set 28 opposite end of the cap 26 on the inside with an inclined slideway 31, on which the edge 13 of the locking cam 9 or the like acts as soon as it has emerged from the longitudinal slot 11 sufficiently far. The cap 26 is then forcibly moved in the longitudinal direction, so that its hook extension 28 disengages from the longitudinal slot 29.

In ihrer Deckwand 32 hat die Kappe 26 einen Durchlaß 33 für das Druckstück 18 und/oder den dieses tragenden Arm 6 des zweiarmigen Hebels 5. Dieser Durchlaß 33 erstreckt sich dabei etwa über die Länge der Wand bzw. des Steges 25 der Kappe 26, welche bzw. welcher auf der Stulpschiene 1 aufliegt. In der Wand bzw. dem Steg 25 kann ein Längsschlitz 34 so vorgesehen werden, daß in diese der Längssteg 8 der Fehlbedienungssperre 4 eintreten kann, wenn dieser beim Ausrücken der Fehlbedienungssperre 4 hochgeschwenkt wird.In its top wall 32, the cap 26 has a passage 33 for the pressure piece 18 and / or the arm 6 of the two-armed lever 5 carrying it. This passage 33 extends approximately over the length of the wall or the web 25 of the cap 26, which or which rests on the faceplate 1. In the wall or the web 25, a longitudinal slot 34 can be provided so that the longitudinal web 8 of the misuse lock 4 can enter it when it is pivoted up when the misuse lock 4 is disengaged.

Die Kappe 26 kann von ,einem einstückigen Formteil aus Metall-Druckguß oder Kunststoff-Spritzguß gebildet werden, wobei sie und auch das ihren Durchlaß 33 durchgreifende Druckstück 18 zu einer Normalebene der Stulpschiene 1 symmetrisch gestaltet sind, um ohne weiteres Rechts- und Linksanschlag der Fehlbedienungssperre 4 zu ermöglichen.The cap 26 can be formed from a one-piece molded part made of die-cast metal or plastic injection molding, whereby it and also the pressure piece 18 penetrating through its passage 33 are designed symmetrically with respect to a normal plane of the faceplate 1, so that the maloperation lock can be stopped right and left 4 to enable.

In Fig. 3 der Zeichnung ist zu sehen, wie einerseits die Schnapp-Rastverbindung der eigentlichen Fehlbedienungssperre 4 und andererseits auch die Schnapp-Rastverbindung der diese übergreifende Kappe 26 mit der Stulpschiene 1 bewirkt werden kann.In Fig. 3 of the drawing it can be seen how, on the one hand, the snap-lock connection of the actual maloperation lock 4 and, on the other hand, the snap-lock connection of the cap 26 spanning this with the faceplate 1 can be effected.
