Description

Die Erfindung betrifft eine Sperrvorrichtung gegen unbefugtes Öffnen des Flügels von Fenstern, Türen od. dgl., welcher einerseits mittels eines Treibstangenbeschlages in seiner Schließstellung am feststehenden Rahmen durch Verschlußstücke hintergreifende Nocken od. dgl. verriegelbar ist sowie andererseits über durch den Treibstangenbeschlag umstellbare bzw. wechselseitig ein- und ausrückbare Gelenkteile wahlweise in zwei verschiedene Öffnungstellungen, z.B. in eine Dreh-Öffnungsstellung und eine Kipp-Öffnungsstellung, bringbar ist, bei welcher ein auf einer Grundplatte gleitender Schlitten vorgesehen ist, der einen parallel zur Rahmenebene vorspringenden und raumseitig vor der Bewegungsbahn eines Nockens od. dgl. des Treibstangenbeschlages liegenden Anschlag trägt, welcher parallel zur Bewegungsbahn des Nockens od. dgl. aus einer-unwirksamen-Grundstellung wenigstens in eine einer der beiden Öffnungs-Schaltstellungen zugeordnete -wirksame-Blockier-Position verlagerbar und darin fixierbar ist, wobei der Schlitten ein quer zu seiner Verschieberichtung wirksames Fixierglied trägt, über das er sowohl in seiner Grundstellung als auch in jeder Blockier-Position mit einem an der Grundplatte ortsfest vorgesehenen Fixiereingriff kuppelbar ist, wobei der Schlitten mit einem abgewinkelten Fußteil in einen Längsschlitz der Grundplatte längsschiebbar eingreift, wobei einerseits an einer Längsfläche dieses Fußteils mindestens ein Raststück vorgesehen ist, dem an der im zugeordneten Längsfläche des Längsschlitzes in der Grundplatte andererseits mehrere im Abstand voneinander liegende Fixiereingriffe zugeordnet sind, und wobei das Fixierglied an seinem nach vorne aus dem Schlitten herausragenden Ende mit einem Eingriff für Betätigungswerkzeug versehen ist.The invention relates to a locking device against unauthorized opening of the sash of windows, doors or the like, which on the one hand can be locked by means of an espagnolette fitting in its closed position on the fixed frame by cams engaging behind locking pieces or the like, and on the other hand can be changed or alternately by the espagnolette fitting articulated parts that can be engaged and disengaged in two different opening positions, e.g. can be brought into a rotary open position and a tilt open position, in which a slide is provided on a base plate, which carries a stop that projects parallel to the plane of the frame and is located in front of the movement path of a cam or the like of the connecting rod fitting, which is parallel to the path of movement of the cam or the like. from an ineffective basic position at least into one of the two opening switch positions associated with an effective blocking position, and can be fixed therein, the carriage carrying a fixing member effective transversely to its direction of displacement, via which it can be coupled both in its basic position and in any blocking position with a fixing engagement provided in a fixed manner on the base plate, the slide engaging in a longitudinally slidable manner in an elongated foot part in a longitudinal slot of the base plate, with on the one hand at least one locking piece on a longitudinal surface of this foot part is provided, on the one hand in the associated longitudinal surface of the longitudinal slot in the base plate, a plurality of spaced-apart fixing interventions are assigned, and wherein the fixing member is provided at its front end projecting out of the carriage with an engagement for actuating tool.

Eine Sperrvorrichtung dieser Art ist bereits bekannt durch EP-A2 0 150 653. Bei dieser bekannten Sperrvorrichtung liegt der Betätigungseingriff des Fixiergliedes für den Sperriegel eines längs einerTreibstange zwischen einer Grundstellung und einer Blockier-Position begrenzt linear verlagerbaren Verriegelungselementes an der freien Kopfseite des letzteren. Da sich dabei das Verriegelungselement parallel zur Flügelebene erstreckt, ist eine Zugangsmöglichkeit zum Betätigungseingriff für den Sperriegel auch lediglich in Richtung parallel zur Fensterebene gegeben.A locking device of this type is already known from EP-A2 0 150 653. In this known locking device, the actuating engagement of the fixing member for the locking bolt of a locking element which can be displaced linearly along a drive rod between a basic position and a blocking position lies on the free head side of the latter. Since the locking element extends parallel to the sash plane, there is only one possibility of actuating the locking bolt in the direction parallel to the window plane.

Die Betätigung einer Sperrvorrichtung der bekannten Art ist daher in der nicht blockierten Öffnungsstellung (Kippstellung) des Flügels nur dann möglich, wenn diese sich am Flügel befindet. Bei einer Montage derselben am feststehenden Rahmen ist hingegen die Zugangsmöglichkeit zum Fixierglied des Sperriegels und damit die Umstellung der Sperrvorrichtung praktisch nicht zu verwirklichen, weil man dann an die Rahmenfalzfläche vom Rauminneren her nicht herankommt.The actuation of a locking device of the known type is therefore only possible in the non-blocked open position (tilting position) of the wing when it is on the wing. If the same is installed on the fixed frame, on the other hand, the possibility of access to the fixing element of the locking bolt and thus the conversion of the locking device is practically impossible to achieve, because then one cannot get to the frame rebate surface from the interior of the room.

Bei engen Einbauverhältnissen, und zwar insbesondere bei geringen Blendrahmenfreimaßen gegenüber der benachbarten Mauerleibung, ist die Betätigung der bekannten Sperrvorrichtung in der nicht blockierten Öffnungsstellung (Kippstellung) des Flügels aber selbst dann zumindest erheblich erschwert, wenn die das Verriegelungselement zwischen einer Grundstellung und einer Blockier-Position linear verlagerbar tragende Treibstange am Flügel eingebaut ist. Es ist nämlich nötig, zur Betätigung des Sperriegels über den Werkzeugeingriff seines Fixiergliedes zumindest ein winkelförmig abgebogenes (spezielles) Betätigungswerkzeug zu benutzten.In tight installation conditions, and in particular with small frame dimensions compared to the adjacent wall reveal, the operation of the known locking device in the non-blocked open position (tilt position) of the wing is at least considerably more difficult even if the locking element between a basic position and a blocking position linearly displaceable drive rod is installed on the wing. It is namely necessary to use at least one angularly bent (special) actuating tool to actuate the locking bolt via the tool engagement of its fixing member.

Gegenüber einer bekannten Sperrvorrichtung der eingangs spezifizierten Gattung zeichnet sich diejenige nach der vorliegenden Erfindung zur Vermeidung der genannten Nachteile dadurch aus, daß der Schlitten mit dem Fußteil auch begrenzt querverlagerbar in den Längsschlitz der am feststehenden Rahmen vorgesehenen Grundplatte eingreift, daß als Fixierglied ein aus einem Schraubbolzen und/oder einem Federkörper bestehendes Druckstück vorgesehen ist, welches an der den Fixiereingriffen gegenüberliegenden rückwärtigen Längsfläche des Längsschlitzes abgestützt bzw. abstützbar ist, und daß über das Fixierglied das Raststück des Fußteils formschlüssig in einen der Fixiereingriffe des Längsschlitzes einrückbar ist.Compared to a known locking device of the type specified at the outset, the one according to the present invention, in order to avoid the disadvantages mentioned, is characterized in that the slide with the foot part also engages transversely to a limited extent in the longitudinal slot of the base plate provided on the fixed frame, that as a fixing member, a screw bolt and / or a spring element is provided which is supported or can be supported on the rear longitudinal surface of the longitudinal slot opposite the fixing engagements, and that the locking piece of the foot part can be positively inserted into one of the fixing engagements of the longitudinal slot via the fixing member.

Es wird hierdurch eine Sperrvorrichtung geschaffen, die in vorteilhafter Weise zu ihrer Betätigung auch bei engen Einbauverhältnissen in der nicht blockierten Öffnungsstellung des Flügels noch zugänglich ist und die trotzdem eine Anordnung ermöglicht, welche bei in Schließlage am feststehenden Rahmen befindlichem Flügel völlig im Falzraum aufgenommen ist. Die Betätigung der Sperrvorrichtung ist dabei über einen Werkzeugeingriff am nach vorne herausragenden Ende des Fixiergliedes problemlos möglich.In this way, a locking device is created which is advantageously still accessible for its actuation even in tight installation conditions in the non-blocked opening position of the sash and which nevertheless enables an arrangement which is completely accommodated in the rebate space when the sash is in the closed position on the fixed frame. The actuation of the locking device is easily possible via a tool engagement at the end of the fixing member protruding towards the front.

Nach dem Erfindungsmerkmal des Anspruchs 2 weist das Druckstück an seinem vom Längsschlitz der Grundplatte abgewendeten Ende als Werkzeugeingriff z.B. einen Innensechskant für einen Steckschlüssel auf, mittels dessen es zwecks Axialverstellung verdrehbar ist.According to the inventive feature of claim 2, the pressure piece has at its end facing away from the longitudinal slot of the base plate as a tool engagement e.g. an internal hexagon for a socket wrench, by means of which it can be rotated for the purpose of axial adjustment.

Für ein dauerhaft einwandfreies Führungsverhalten der Sperrvorrichtung ist nach Anspruch 3 erfindungsgemäß vorgeschlagen, daß das Fußteil des Schlittens an der Unterseite der Grundplatte mit einer Stützplatte verbunden ist, die beidseitig des Längsschlitzes an der Grundplatte ihr Widerlager hat. Auf den Schlitten einwirkende Kippkräfte werden auf diese Art und Weise sichervon der Grundplatte abgefangen.For a permanently faultless guiding behavior of the locking device according to the invention it is proposed according to claim 3 that the foot part of the carriage is connected to the underside of the base plate with a support plate which has its abutment on both sides of the longitudinal slot on the base plate. In this way, tilting forces acting on the slide are safely absorbed by the base plate.

Besonders bewährt hat sich eine Bauart der Sperrvorrichtung, bei welcher die Fixiereingriffe der Grundplatte gemäß Anspruch 4 aus nockenartig von der Seite her in den Längsschlitz hineinragenden Vorsprüngen bestehen, denen komplementäre Vertiefungen an der zugewendeten Seitenfläche des Fußteils zugeordnet sind. Jeder Einstell-Position des Schlittens können dabei nach Anspruch 5 an der Grundplatte jeweils zwei Vorsprünge und zwei Vertiefungen zugeordnet sein, so daß eine stabile Lagenfixierung des Schlittens dauerhaft gewährleistet ist.A type of locking device has proven particularly useful, in which the fixing engagements of the base plate according to claim 4 are cam-like the side protruding into the longitudinal slot consist of complementary recesses on the side surface of the foot part facing. Each setting position of the slide can be assigned two projections and two depressions on the base plate, so that a stable position fixation of the slide is permanently ensured.

Besonders einfach ist es dabei, wenn gemäß Anspruch 6 die Vertiefungen jeweils durch die voneinander abgewendeten Flächen des Fußteils gebildet sind und wenn entsprechend dem Anspruch 7 sowohl die Vorspünge als auch die Vertiefungen mitgegeneinander geneigten Stützflächen versehen sind.It is particularly simple in this case if, according to claim 6, the depressions are each formed by the surfaces of the foot part facing away from one another and if, according to claim 7, both the projections and the depressions are provided with support surfaces inclined towards one another.

Der beliebige Rechts- und Linksanschlag der Sperrvorrichtung läßt sich problemlos dann erreichen, wenn gemäß Anspruch 8 Grundplatte und Schlitten jeweils zu einer Querebene symmetrisch gestaltet sind.Any right and left stop of the locking device can be easily achieved if the base plate and slide are each designed symmetrically to a transverse plane.

Die erfindungsgemäße Sperrvorrichtung eignet sich nicht nurzurAnwendung an Fenstern oder Türen mit Drehkippflügel. Vielmehr läßt sie sich auch bei anderen Fenster-Bauarten benutzen, bei denen der Flügel aus seiner Schließlage wahlweise in zwei verschiedene Öffnungsstellungen bewegen läßt und dabei mittels eines in drei verschiedene Schaltstellungen bringbaren Treibstangenbeschlages betätigt wird.The locking device according to the invention is not only suitable for use on windows or doors with a tilt and turn sash. Rather, it can also be used in other window types in which the sash can be moved from its closed position to two different opening positions and is actuated by means of an espagnolette fitting which can be brought into three different switching positions.

Derartige Fenster können beispielsweise mit Kipp-Schwingflügeln, Klapp-Schwingflügeln, Dreh-Wendeflügeln oder auch parallelabstellbaren Schiebe-Kippflügeln ausgestattet sein.Windows of this type can be equipped, for example, with tilt-and-swing doors, folding-swing doors, turn-and-turn wings or also parallel-adjustable sliding and tilting doors.

Die in der Zeichnung dargestellte Sperrvorrichtung 1 wird beispielsweise in ein Drehkippfensteroder eine Drehkipptür 2 eingebaut, das bzw. die den feststehenden Rahmen 3 und den zugehörigen Flügel 4 umfaßt.The locking device 1 shown in the drawing is installed, for example, in a tilt-and-turn window or a tilt-and-tilt door 2 which comprises the fixed frame 3 and the associated wing 4.

Feststehender Rahmen 3 und Flügel 4 des Drehkippfensters 2 sind dabei beispielsweise aus Leichtmetall- oder Kunststoff-Hohlprofilen gefertigt.Fixed frame 3 and sash 4 of the tilt-and-turn window 2 are made, for example, from light metal or plastic hollow profiles.

In das Fenster bzw. die Tür 2 ist ein Treibstangenbeschlag eingebaut, bei dem am Flügel 4 Treibstangen 5 längsschiebbar geführt sind, die an ihrer dem feststehenden Rahmen 3 zugewendeten Seite Nocken 6 od. dgl. tragen, welche mit am feststehenden Rahmen sitzenden - nicht dargestellten - Verschlußstücken zusammenwirken können, um den flügel 4 in seiner Schließlage am feststehenden Rahmen zu verriegeln.In the window or door 2, an espagnolette fitting is installed, in which 4 espagnolettes 5 are guided longitudinally on the wing and carry cams 6 or the like on their side facing the fixed frame 3, which, not shown, are seated on the fixed frame - Locking pieces can cooperate to lock the wing 4 in its closed position on the fixed frame.

Über die Treibstangen 5 des Treibstangenbeschlages können darüberhinaus - ebenfalls nicht dargestellte - Gelenkteile zwischen Flügel 4 und feststehendem Rahmen 3 wechselseitig ein- und ausgerückt werden, dergestalt, daß sich der Flügel 4 relativ zum feststehenden Rahmen 3 entweder um eine seitlich lotrechte Achse in Drehstellung öffnenläß, oder aber um eine untere waagerechte Achse in Kippstellung geöffnet werden kann.Via the connecting rods 5 of the connecting rod fitting, joint parts between the sash 4 and the fixed frame 3 can also be mutually engaged and disengaged, in such a way that the sash 4 can be opened relative to the fixed frame 3 either about a laterally perpendicular axis in the rotational position, or can be opened in a tilted position about a lower horizontal axis.

Um alle vorstehend angegebenen Funktionen erfüllen zu können, sind die Treibstangen 5 des Treibstangenbeschlages relativ zum Flügel 4 in drei verschiedene Schaltstelungen bewegbar, nämlich

  • die Verschluß-Schaltstellung V
  • die Drehöffnungs-Schaltstellung D und
  • die Kippöffnungs-Schaltstellung K.
In order to be able to fulfill all of the above-mentioned functions, the drive rods 5 of the drive rod fitting can be moved in three different switching positions relative to the wing 4, namely
  • the shutter switch position V
  • the rotary opening switch position D and
  • the tilt opening switch position K.

In der Verschluß-Schaltstellung nehmen die Treibstangen 5 des Treibstangenbeschlages beispielsweise eine Schaltstellung ein, die in den Fig. 1 bis 4 anhand des Nockens 6 mit 6V gekennzeichnet ist. Die Drehöffnungs-Schaltstellung entspricht dort jeweils der Position 6D, während die Kippöffnungs-Schaltstellung durch die Position 6K gekennzeichnet ist.In the closed switch position, the drive rods 5 of the drive rod fitting take up a switch position, for example, which is identified by 6V in FIGS. 1 to 4 on the basis of the cam 6. The rotary opening switch position corresponds to position 6D, while the tilt opening switch position is identified by position 6K.

Den an den flügelseitigen Treibstangen 5 sitzenden Nocken 6 sind am feststehenden Rahmen 3, wie bereits weiter oben erwähnt wurde, ortfeste Verschlußstücke zugeordnet. Dieses so, daß die Verschlußstücke jeweils in der Position 6V von den Nocken 6 hintergriffen sind und somit der Flügel 4 am feststehenden Rahmen 3 des Fensters bzw. der Tür 2 in seiner Schließlage verriegelt ist.The cams 6 seated on the wing-side drive rods 5 are assigned fixed locking pieces on the fixed frame 3, as already mentioned above. This in such a way that the locking pieces are each engaged in the position 6V by the cams 6 and thus the wing 4 is locked in its closed position on the fixed frame 3 of the window or the door 2.

In den Positionen 6D und 6K sind jedoch die Nocken 6 mit den rahmenseitigen Verschlußstücken außer Eingriff, so daß der Flügel 4 relativ zum feststehenden Rahmen 3 entweder in die Drehstellung oder aber in die Kippstellung geöffnet werden kann. um sowohl das Drehöffnen als auch das Kippöffnen des Flügels 4 unbehindert zu ermöglichen, muß die im Bereich der Verschlußseite des Fensters bzw. der Tür 2 am feststehenden Rahmen 3 eingebaute Sperrvorrichtung 1 jeweils die aus den Fig. 1 und 3 ersichtliche Grundstellung einnehmen.In positions 6D and 6K, however, the cams 6 are disengaged from the frame-side locking pieces, so that the wing 4 can be opened either in the rotational position or in the tilted position relative to the fixed frame 3. In order to enable both the pivot opening and the tilt opening of the sash 4 without hindrance, the lock 3 installed in the area of the closure side of the window or door 2 on the fixed frame 3 must be provided direction 1 each assume the basic position shown in FIGS. 1 and 3.

Soll hingegen eine unbefugte Bewegung des Flügels 4 in die Drehöffnungsstellung blockiert werden, dann ist es erforderlich, die Sperrvorrichtung 1 die in die Blockier-Position zu bringen, wie sie den Fig. 2, 4 und 5 entnommen werden kann.If, on the other hand, an unauthorized movement of the wing 4 into the rotary opening position is to be blocked, then it is necessary to bring the blocking device 1 into the blocking position, as can be seen in FIGS. 2, 4 and 5.

Die aus den Fig. 1 bis 9 der Zeichnung ersichtliche Sperrvorrichtung 1 weist eine Grundplatte 11 auf, die am feststehenden Rahmen 3 des Fensters oder der Tür 2, beispielsweise in einer im Querschnitt etwa C-förmigen, hinterschnittenen Profilnut 7, verankert werden kann. Hierzu untergreift eine an die Grundplatte 11 angeformte Hakenleiste 12 einen Winkelsteg 8, der hinterschnittenen Profilnut 7, während ein hierzu spiegelbildlicherWinkelsteg 9 der hinterschnittenen Profilnut 7 jeweils von Klemmschrauben 13 unterfaßt werden kann, die axial verstellbar in der Grundplatte 11 sitzen, wie das deutlich der Fig. 9 zu entnehmen ist.The locking device 1 shown in FIGS. 1 to 9 of the drawing has a base plate 11 which can be anchored to the fixed frame 3 of the window or door 2, for example in an undercut profile groove 7 which is approximately C-shaped in cross section. For this purpose, a hook bar 12 formed on the base plate 11 engages under an angled web 8, the undercut profile groove 7, while a mirror-image angular web 9 of the undercut profile groove 7 can be underpinned by clamping screws 13, which are axially adjustable in the base plate 11, as is clearly shown in FIG 9 can be seen.

In die Grundplatte 11 der Sperrvorrichtung 1 ist ein Längsschlitz 14 eingeformt, dessen eine, nämlich die rückwärtige, Längsfläche 15 einen geraden Verlauf hat. Die gegenüberliegende Längsfläche 16 dieses Längsschlitzes ist demgegenüber an mehreren, beispielsweise vier, in Längsrichtung verteilten Stellen mit nockenartig von der Seite her in den Längsschflitz 14 hineinragenden Vorsprüngen 17a, 17b, 17c und 17b versehen, dergestalt, daß diese Vorsprünge 17a bis 17d die Breite des Längsschlitzes 14 bereichsweise auf ein vorgegebenes Mindestmaß 21 einengen.A longitudinal slot 14 is formed in the base plate 11 of the locking device 1, one of which, namely the rear, longitudinal surface 15 has a straight course. The opposite longitudinal surface 16 of this longitudinal slot, on the other hand, is provided at several, for example four, longitudinally distributed locations with projections 17a, 17b, 17c and 17b projecting from the side into the longitudinal slot 14 in such a way that these projections 17a to 17d are the width of the Constrict the longitudinal slot 14 in certain areas to a predetermined minimum dimension 21.

In den Längsschlitz 14 der Grundplatte 11 greift von oben her ein abgewinkeltes Fußteil 18 eines Schlittens 19 ein. Dieses fußteil 18 hat dabei eine Breite 20, die etwas kleiner bemessen ist als die durch die Nocken 17a bis 17d eingeengte Mindestbreite 21 des Längsschlitzes 14.An angled foot part 18 of a slide 19 engages in the longitudinal slot 14 of the base plate 11 from above. This foot part 18 has a width 20 which is dimensioned somewhat smaller than the minimum width 21 of the longitudinal slot 14 narrowed by the cams 17a to 17d.

An der Unterseite der Grundplatte 11 ist im unmittelbaren Anschluß an den Längsschlitz 14 eine flache Vertiefung 22 vorgesehen, in welcher eine Stützplatte 23 aufgenommen ist, mit der der Fußteil 18 des Schlittens 19 in Verbindung, vorzugsweise fester Verbindung, steht. Mittels dieser Stützplatte 23 wird der Schlitten 19 mit der Grundplatte 11 in Verbindung gehalten, und zwar derart, daß sich die Grundplatte 23 in jedem Falle im Anschluß an die beiden Längsflächen 15 und 16 Längsschlitzes 14 an der oberen Begrenzungsfläche der flachen Vertiefung 22 sicher abstützt. Der Schlitten 19 trägt an seiner Oberseite einen Anschlag 24, der im Einbauzustand der Sperrvorrichtung 1 parallel zur Ebene des feststehenden Rahmens 3 gegen die Falzfläche des Flügels 4 vorspringt, wie das deutlich den Fig. 6 und 8 entnommen werden kann.On the underside of the base plate 11, a flat recess 22 is provided in the direct connection to the longitudinal slot 14, in which a support plate 23 is received, with which the foot part 18 of the slide 19 is connected, preferably a fixed connection. By means of this support plate 23, the carriage 19 is held in connection with the base plate 11, in such a way that the base plate 23 is securely supported in any case following the two longitudinal surfaces 15 and 16 longitudinal slots 14 on the upper boundary surface of the flat recess 22. The carriage 19 carries on its upper side a stop 24 which, in the installed state of the locking device 1, projects parallel to the plane of the fixed frame 3 against the folded surface of the wing 4, as can be clearly seen in FIGS. 6 and 8.

Der Anschlag 24 am Schlitten 19 der Sperrvorrichtung 1 wird dabei einem der Nocken 6 od. dgl. zugeordnet, die an einer Treibstange 5 des in den Flügel 4 eingebauten Treibstangenbeschlages sitzen. Bevorzugt wird die Zuordnung des Anschlags 24 bzw. der Sperrvorrichtung 1 zu einem Nocken 6 od. dgl., der an der Treibstange 5 sitzt, welche längs der Verschlußseite des Flügels 4 verschiebbar geführt ist. Denkbar wäre es allerdings auch, die Sperrvorrichtung 1 mit dem Anschlag 24 einem Nocken 6 od. dgl. zuzuordnen, welcher nahe einer verschlußseitigen Ecke des Flügels 4, aber an einer quer zu dieser Verschlußseite verschiebbar am Flügel 4 angeordneten Treibstange 5 sitzt.The stop 24 on the slide 19 of the locking device 1 is assigned to one of the cams 6 or the like, which are seated on a drive rod 5 of the drive rod fitting installed in the wing 4. The assignment of the stop 24 or the locking device 1 to a cam 6 or the like, which is seated on the drive rod 5, which is displaceably guided along the closure side of the wing 4, is preferred. However, it would also be conceivable to assign the locking device 1 with the stop 24 to a cam 6 or the like, which sits near a lock-side corner of the wing 4, but on a drive rod 5 which is displaceable transversely to this lock side on the wing 4.

In der- unwirksamen - Grundstellung der Sperrvorrichtung 1 nimmt der Schieber 19 mit dem Anschlag 24 bei Rechtsanschlag die aus Fig. 1 ersichtliche Relativlage zur Grundplatte 11 ein, d. h. er ist der Verschluß-Schaltstellung 6V des nockens 6 od. dgl. zugeordnet. Die gleiche - unwirksame - Grundstellung des Schiebers 19 mit dem Anschlag 24 relativ zur Grundplatte 11 bei Linksanschlag des Flügels geht aus Fig. 3 der Zeichnung hervor.In the - ineffective - basic position of the locking device 1, the slider 19 with the stop 24 assumes the relative position to the base plate 11 shown in FIG. H. it is assigned to the locking switch position 6V of the cam 6 or the like. The same - ineffective - basic position of the slide 19 with the stop 24 relative to the base plate 11 when the wing stops to the left can be seen in FIG. 3 of the drawing.

In den Fig. 2 und 4 der Zeichnung ist jeweils für Rechts- und für Linksanschlag die Blockier-Position des Schiebers 19 mit dem Anschlag 24 relativ zur Grundplatte 11 dargestellt. In diesem Falle befindet sich der Schieber 19 mit dem Anschflag 24 nämlich in einer Lage, die der Schaltstellung 6D des Nockens 6 od. dgl. zugeordnet ist.2 and 4 of the drawing, the blocking position of the slide 19 with the stop 24 relative to the base plate 11 is shown for right and left stop. In this case, the slide 19 with the stop 24 is in a position which is assigned to the switching position 6D of the cam 6 or the like.

In der Schaltstellung 6D des Nockens 6 od. dgl., welche - wie bereits weiter oben erwähnt - der Drehöffnungs-Schaltstellung des Treibstangenbeschlages zugeordnet ist, kann dann der Flügel 4 relativ zum festehenden Rahmen 3 nicht geöffnet werden, weil der Nocken 6 od. dgl. sich nicht an dem Anschlag 24 des Schlittens 19 der Sperrvorrichtung 1 vorbeibewegen läßt.In the switching position 6D of the cam 6 or the like, which - as already mentioned above - is assigned to the rotary opening switching position of the connecting rod fitting, the wing 4 cannot be opened relative to the fixed frame 3 because the cam 6 or the like cannot be moved past the stop 24 of the slide 19 of the locking device 1.

In der Verschluß-Schaltstellung 6V des Nockens 6 od. dgl. ist ein Öffnen des Flügels 4 relativ zum feststehenden Rahmen 3 des Fensters 2 ebenfalls nicht möglich, weil alle weiteren Nocken 6 od. dgl. die üblicherweise am feststehenden Rahmen 3 befindlichen Verschlußstücke riegelnd hintergreift.In the closed switch position 6V of the cam 6 or the like, opening of the wing 4 relative to the fixed frame 3 of the window 2 is also not possible because all other cams 6 or the like engage behind the locking pieces which are usually located on the fixed frame 3 .

Lediglich in der Schaltstellung 6K der Nocken 6 od. dgl. ist das Öffnen des Flügels 4 relativ zum festehenden Rahmen 3 des Fensters 2 möglich, weil dann nämlich die den üblichen Verschlußstücken zugeordneten Nocken 6 od. dgl. mit diesen außer Eingriff sind und darüberhinaus der der Sperrvorrichtung 1 zugeordnete Nocken 6 od. dgl. sich in der Schaltstellung 6K befindet. Ein Öffnen des flügels 4 relativ zum feststehenden Rahmen 3 des Fensters 2 durch eine Kippbewegung wird also mittels der Sperrvorrichtung 1 nicht behindert.Only in the switch position 6K of the cams 6 or the like is it possible to open the sash 4 relative to the fixed frame 3 of the window 2, because then the cams 6 or the like assigned to the usual locking pieces are disengaged from them and, moreover, the the locking device 1 assigned cam 6 or the like. is in the switching position 6K. Opening the sash 4 relative to the fixed frame 3 of the window 2 by a tilting movement is therefore not hindered by the locking device 1.

Sowohl in den aus den Fig. 1 und 3 ersichtlichen - unwirksamen - Grundstellungen als auch in den den Fig. 2 und 4 zu entnehmenden - wirksamen - Blockierpositionen wird der den Anschlag 24 tragende Schieber 19 mittels eines Fixiergliedes 25 über sein Fußteil 18 im Längsschlitz 14 der Grundplatte 11 festgelegt. Hierzu wirkt das im Schlitten 19 sitzende Fixierglied 25, welches gemäß den Fig. 1 bis 7 von einem als Druckstück wirkenden Schraubbolzen gebildet wird, auf die Längsfläche 15 des Längsschlitzes 14 der Grundplatte 11 ein, wie das deutlich die Fig. 1 bis 4 und 6 erkennen lassen. Durch dieses Fixierglied 25 wird dabei das Fußteil 18 des Schiebers 19 als Raststück jeweils zwischen zwei Nocken 17a und 17b (Fig. 1) bzw. 17d und 17c (Fig. 3) oder aber zwischen die beiden Nocken 17b und 17c (Fig. 2 und 4) quer zu seiner möglichen Verschieberichtung eingerückt und damit jeweils gegen Verschieben blockiert.Both in the - ineffective - basic positions shown in FIGS. 1 and 3 and in the - effective - blocking positions shown in FIGS. 2 and 4, the slide 19 carrying the stop 24 is fastened by means of a fixing member 25 via its foot part 18 in the longitudinal slot 14 the base plate 11 set. For this purpose, the fixing member 25 seated in the slide 19, which according to FIGS. 1 to 7 is formed by a screw bolt acting as a pressure piece, acts on the longitudinal surface 15 of the longitudinal slot 14 of the base plate 11, as clearly shown in FIGS. 1 to 4 and 6 reveal. By means of this fixing member 25, the foot part 18 of the slider 19 is in the form of a latching piece between two cams 17a and 17b (FIG. 1) or 17d and 17c (FIG. 3) or between the two cams 17b and 17c (FIGS. 2 and 4) indented transversely to its possible direction of displacement and thus blocked against displacement.

Um in jedem Falle einen spielfreien Sitz des als Druckstück mit den Vorsprüngen 17a bis 17b zusammenwirkenden Fußteils 18 des Schiebers 19 zu erhalten, ist es vorteilhaft, sowohl die Vorsprünge 17a bis 17b mit gegeneinander geneigten Stützflächen 26 als auch die damit zusammenwirkenden Endflächen 27 des das Druckstück bildenden Fußteils 18 gegeneinander geneigt verlaufend vorzusehen. Über das Fixierglied 25 lassen sich die gegeneinander geneigten Stützflächen 27, die von den Endflächen des Fußteils 18 gebildet werden, praktisch keilartig zwischen die Stützflächen zweier benachbarter Vorsprünge 17a und 17b bzw. 17d und 17c bzw. 17b und 17c drücken und dadurch exakt entweder in der Grundstellung (Fig. 1 und 3) oder in der Blockier-Position (Fig. 2 und 4) des Schiebers 19 bzw. des Anschlags 24 an der Grundplatte 11 festlegen.In order in any case to obtain a play-free fit of the foot part 18 of the slide 19, which acts as a pressure piece with the projections 17a to 17b, it is advantageous to have both the projections 17a to 17b with mutually inclined support surfaces 26 and the end faces 27 of the pressure piece interacting therewith providing foot portion 18 inclined to each other. Via the fixing member 25, the mutually inclined support surfaces 27, which are formed by the end surfaces of the foot part 18, can be practically wedge-like pressed between the support surfaces of two adjacent projections 17a and 17b or 17d and 17c or 17b and 17c and thereby exactly either in the Determine the basic position (FIGS. 1 and 3) or in the blocking position (FIGS. 2 and 4) of the slide 19 or of the stop 24 on the base plate 11.

Zum Zwecke der Verlagerung des Schlittens 19 mit dem Anschlag 24 innerhalb des Längsschlitzes 14 der Grundplatte 11 ist es nötig, zunächst das Fixierglied bzw. den Schraubenbolzen 25 zu lösen, also in einen genügend großen Abstand von der Längsfläche 15 des Längsschlitzes 14 zu bringen. Sodann wird der Schieber 19 mit seinem Fußteil 18 quer zum Verlauf des Längsschlitzes 14 von dennen Längsfläche 16 weg bis gegen die Längsfläche 15 verlagert. Hierdurch kommt das mit seinen Stützflächen 27 als Raststück wirkende Fußteil 18 mit den Vorsprüngen 17a, 17b bzw. 17b, 17c, bzw. 17b, 17c außer Eingriff. Nunmehr läßt sich der Schieber 19 mit dem Anschlag 24 in Längsrichtung des Längsschlitzes 14 der Grundplatte 11 verlagern und damit aus der jeweiligen Grundstellung in die Blockier-Position bzw. aus der Blockier-Position in die jeweilige Grundstellung bewegen. Daraufhin wird daß Fixierglied bzw. der Schraubbolzen 25 wieder gegen die Längsfläche 15 des Längsschlitzes 14 zur Wirkung gebracht und das Fußteil 18 des Schiebers 19 zwischen den Vorsprüngen 17a, 17b bzw. 17d, 17c bzw. 17b, 17c an der Grundplatte 11 festgelegt, wie das die Fig. 1 bis 4 und 6 deutlich machen.For the purpose of displacing the carriage 19 with the stop 24 within the longitudinal slot 14 of the base plate 11, it is necessary to first loosen the fixing member or the screw bolt 25, that is to say to bring them into a sufficiently large distance from the longitudinal surface 15 of the longitudinal slot 14. Then the slider 19 is displaced with its foot part 18 transversely to the course of the longitudinal slot 14 away from the longitudinal surface 16 thereof and against the longitudinal surface 15. As a result, the foot part 18, which acts as a latching piece with its support surfaces 27, disengages from the projections 17a, 17b or 17b, 17c or 17b, 17c. Now the slide 19 can be displaced with the stop 24 in the longitudinal direction of the longitudinal slot 14 of the base plate 11 and thus moved from the respective basic position into the blocking position or from the blocking position into the respective basic position. Then that fixing member or the screw 25 is brought back against the longitudinal surface 15 of the longitudinal slot 14 and the foot part 18 of the slider 19 between the projections 17a, 17b or 17d, 17c or 17b, 17c on the base plate 11, such as that make FIGS. 1 to 4 and 6 clear.

Aus Fig. 8 geht noch hervor, daß das Fixierglied für den Schlitten 19 nicht unbedingt von einem als Druckstück wirkenden Schraubbolzen 25 gebildet werden muß. Es kann vielmehr auch aus einem axial verschiebbar geführten Bolzen 28 bestehen, der von einer am Schlitten 19 bzw. Anschlag 24 abgestützten Druckfeder 29 beaufschlagt ist und durch diese unter Vorspannung gegen die Längsfläche 15 des Längsschlitzes 14 gehalten wird. Zum Zwecke der Verstellung des Schiebers 19 muß dann der Bolzen 28 entgegen der Wirkung der Druckfeder 29 zurückgezogen werden, damit das Fußteil 18 des Schiebers 19 durch entsprechende Querverlagerung mit den Vorsprüngen 17a, 17b bzw. 17d, 17c bzw. 17b, 17c außer Eingriff gebracht werden kann.8 also shows that the fixing member for the carriage 19 does not necessarily have to be formed by a screw bolt 25 acting as a pressure piece. Rather, it can also consist of an axially displaceably guided bolt 28 which is acted upon by a compression spring 29 supported on the slide 19 or stop 24 and is held by this under pretension against the longitudinal surface 15 of the longitudinal slot 14. For the purpose of adjusting the slide 19, the bolt 28 must then be withdrawn counter to the action of the compression spring 29, so that the foot part 18 of the slide 19 is disengaged from the projections 17a, 17b or 17d, 17c or 17b, 17c by appropriate transverse displacement can be.

Um das Zurückziehen des Bolzens 28 gegen die Kraft der Druckfeder 29 zu ermöglichen, wäre es denkbar, den Bolzen 28 an seinem nach vorne aus dem Anschlag 24 herausragenden Ende mit einem Kragen zu versehen, der sich mit einem zangenartigen Werkzeug hinterfassen und um das notwendige Maß gegenüber dem Schlitten 19 anziehen läßt, um anschließend zunächst die Querverlagerung und dann die Längsverlagerung des Schlittens relativ zur Grundplatte 11 zu ermöglichen. Ebenso wäre es aber auch denkbar, im Schlitten 19 eine Schraubenfläche 30 oder auch einen Bajonettschlitz auszuformen, an welcher sich der Bolzen 28 unter der Wirkung der Druckfeder 29 mit einem Anschlag 31 abstützt. Durch Relativdrehung des Bolzens 28 zum Schlitten 19 kann in Zusammenwirken des Anschlags 31 mit der Schraubenfläche 30 bzw. dem Bajonettschlitz die Axialverlagerung des Bolzens 28 gegen die Wirkung der Druckfeder 29 bewirkt und dadurch der Bolzen 28 in seine Freigabestellung verlagert werden. Die Rückstellung des Bolzens 28 in seine Fixiferstellung kann selbsttätig unter der Wirkung der Druckfeder 28 erfolgen.In order to allow the withdrawal of the bolt 28 against the force of the compression spring 29, it would be conceivable to provide the bolt 28 with a collar at its end projecting forward from the stop 24, which can be gripped with a pliers-like tool and by the necessary amount can be tightened relative to the carriage 19, in order first to allow the transverse displacement and then the longitudinal displacement of the carriage relative to the base plate 11. However, it would also be conceivable to form a screw surface 30 or a bayonet slot in the slide 19, on which the bolt 28 is supported with a stop 31 under the action of the compression spring 29. By relative rotation of the bolt 28 to the slide 19, the axial displacement of the bolt 28 against the action of the compression spring 29 can be brought about in cooperation with the stop 31 with the screw surface 30 or the bayonet slot, and the bolt 28 can thereby be displaced into its release position. The return of the bolt 28 to its fixative position can take place automatically under the action of the compression spring 28.

Abschließend sei noch darauf hingewiesen, daß das Fixierglied, gleichgültig ob es als Schraubenbolzen 25 oder als federbelasteter Bolzen 28 gestaltet ist, in seinem aus dem Schlitten 19 nach vorne herausragenden Ende einen Werkzeugeingriff, beispielsweise einen Innensechskant 32, enthalten kann, mit dem zur Betätigung des Fixiergliedes ein passender Steckschlüssel in und außer Eingriff bringbar ist.Finally, it should also be pointed out that the fixing member, regardless of whether it is designed as a screw bolt 25 or as a spring-loaded bolt 28, can contain a tool engagement, for example an internal hexagon 32, in its end protruding from the carriage 19, with which to actuate the Fixing member a suitable socket wrench can be brought in and out of engagement.

In den Fig. 2,4 und 5 ist noch angedeutet, daß die Grundplatte 11 und der Schlitten 19 mit dem Anschlag 24 fürden wahlweisen Rechts- und Linksanschlag zur Querebene 10-10 symmetrisch gestaltet sind.2, 4 and 5 it is also indicated that the base plate 11 and the slide 19 are designed symmetrically with the stop 24 for the optional right and left stop to the transverse plane 10-10.
