Abstract

Wing stop, especially for turn-and-tilt window wings, are equipped with a bearing base (5) to be fastened to one of the two window frames (1, 2), especially to the fixed frame (1), with a fixing arm (6) connected pivotably to the bearing base (5) and pivotable outwards transversely to the wing plane, and with a fixing element (7) which is to be brought into fixing engagement with the fixing arm (6) and which is to be fastened to the other frame, especially to the casement (2), the fixing arm (6) being provided with a toothed strip (9) and with a cover strip (12) which is equidistant from this, leaving a displacement path (11) free for the fixing element (7), and in which is located a passage point (13) for the fixing element (7) to be brought into selective blocking engagement with two adjacent blocking teeth (9') provided in the toothed strip. In order to improve such a wing stop so that, whilst being of comparatively simple and stable design, it allows a secure fixing of the wing in different opening positions and permits a movement of the fixing element (7) out of the fixing arm (6) only in the closing position of the window wing or of the wing stop, the blocking teeth (9') of the toothed strip (9) and the associated individual blocking engagement of the fixing element designed as a fixing pin (7) extend over at least half the width of the fixing arm (6), and furthermore there engages on the fixing arm (6) a spring (14) which seeks to press it into the pivoted-out position and which allows the fixing pin (7) to move through the passage point, located in the vicinity of the bearing base (5) and designed as a slot (13) present in the strip (12) only when the fixing arm (6) is in the position pressed against the fixed frame (1). <IMAGE>

Description

Die Erfindung bezieht sich auf einen Flügelfeststeller gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a wing lock according to the preamble of claim 1.

Ein Flügelfeststeller obiger Art ist durch die GB-A-1 500 194 bekannt. Bei einem solchen Flügelfeststeller ist in der Schließlage des Fensterflügels ein Trennen zwischen Feststellarm und Feststellelement möglich, sodaß eine solche Trennung von außen nicht in unbefugter Weise vorgenommen werden kann. In der Schließstellung des Flügels wird der Feststellarm durch den in Höhe seines Durchtrittsschlitzes liegenden Feststellzapfen unter Überwindung der Federkraft in Anlagestellung am Flügel gehalten. Wird dagegen bei Dreh-Kippfenstern der Flügel - wie zumeist - in Kipp-Öffnungsstellung gebracht, so wird dabei der Feststellarm durch die an ihm angreifende Feder zugleich zunehmend ausgeschwenkt und jedenfalls sichergestellt, daß dabei der Feststellzapfen nicht aus dem Durchtrittsschlitz des Feststellarms heraustreten, sondern in dessen Verschiebebahn entlang gleiten kann, um sodann in der gewünschten Kipp-Endstellung mit den entsprechenden Sperrzähnen des Feststellarms in Sperreingriff gebracht zu werden. Soll dagegen der Flügel aus der Schließlage in eine Dreh-Öffnungsstellung verschwenkt werden, so wird dabei zugleich mit dem Drehöffnen der Feststellarm durch Handbetätigung gegen den Festrahmen gedrückt bzw. an letzterem gehalten, so daß der Feststellzapfen dann ungehindert aus dem Durchttrittsschlitz des Feststellarms herausfahren kann. Umgekehrt kann beim Schließen des Flügels aus seiner Drehöffnungsstellung der Feststellzapfen auf der Oberseite des Feststellarms, also auf dessen Abdeckleiste ungehindert entlanggleiten, bis er in dessen Durchtrittsschlitz gelangt und sodann den Feststellarm schließlich wieder fest gegen den Festrahmen drückt.A wing lock of the above type is due to the GB-A-1,500,194. In the case of such a sash arrester, there is a separation between the sash in the closed position Locking arm and locking element possible, so that such separation from the outside is not made in an unauthorized manner can be. The locking arm is in the closed position of the sash through the one at the level of its passage slot Locking pin while overcoming the spring force in the contact position held on the wing. However, this is the case with turn-and-tilt windows the wing - as is usually the case - brought into the tilt-open position, the locking arm is thereby actuated by the spring acting on it at the same time increasingly swung out and at least ensured that the locking pin does not come out of the passage slot step out of the locking arm, but in its Slideway can slide along, then in the desired position Tilt end position with the corresponding ratchet teeth Locking arm to be brought into locking engagement. Should against it the sash from the closed position to a turn-open position be pivoted, so it is at the same time as the rotary opening the locking arm is pressed manually against the fixed frame or held on the latter, so that the locking pin then unhindered from the passage slot of the locking arm can drive out. Conversely, when closing the wing from its opening position of the locking pin on the Top of the locking arm, i.e. unhindered on its cover strip slide along until it gets into its passage slot and then finally the locking arm again firmly against presses the hard frame.

Bei dem bekannten gattungsgemäßen Flügelfeststeller besteht aber noch eine gewisse Funktionsunsicherheit insofern, als hier der Sperreingriff zwischen den Sperrzähnen des Feststellarms und dem Feststellzapfen allein durch die am Feststellarm angreifende und ihn gegen den Feststellzapfen drükkende Feder zustandekommt und aufrechterhalten wird. Mit zunehmendem Erlahmen der Feder wird somit der Sperreingriff unsicherer. Ist dagegen die Feder zu stark bemessen, kann es beim Öffnen des Fensterflügels zu allzu schnellem Sperreingriff dadurch kommen, daß dann der Feststellzapfen ungewollt bereits in die ersten Zahnlücken einspringt.In the known generic wing lock but still a certain functional uncertainty in that than here the locking engagement between the locking teeth of the locking arm and the locking pin only by the on the locking arm attacking and pushing him against the locking pin Spring comes about and is maintained. With increasing The locking engagement thus becomes weak more insecure. If, on the other hand, the spring is too large, it can when opening the window sash to interlock too quickly come that the locking pin is already unwanted jumps into the first tooth gaps.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Flügelfeststeller der eingangs erwähnten Gattung hinsichtlich seines Feststell-Sperreingriffs von der Federkraft unabhängiger und damit noch entsprechend arretiersicherer zu machen und gleichzeitig eine Alternative zur im Stand der Technik angewendeten Drahtfeder zu Finden. Diese Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst.The invention is therefore based on the object of a wing lock of the genus mentioned above with regard to its Locking engagement independent of spring force and thus to make it correspondingly safer to lock and at the same time to find an alternative to the wire spring used in the prior art. This The object is achieved by the features of the characterizing part of claim 1.

Auf diese Weise kann der Feststellzapfen des Fensterflügels in dessen teilweise geöffneter Stellung sicher in der entsprechenden Zahnlücke des Feststellarms geklemmt werden.In this way, the locking pin of the window sash in its partially open position the corresponding tooth gap of the locking arm.

Nach einem weiteren Merkmal der Erfindung kann der Feststellarm am Lagersockel zusätzlich auch noch um eine vertikale Achse drehbeweglich angelenkt sein, so daß der Feststellarm auch zum Feststellen des Flügels in verschiedenen begrenzten Drehöffnungspositionen verwendet werden kann.According to a further feature of the invention, the locking arm on the bearing base also a vertical one Axis be pivoted so that the locking arm also for locking the wing in various limited Rotary opening positions can be used.

Für diesen Fall ist am Lagersockel ein um die vertikale Achse drehbeweglicher Lagerbügel angelenkt, der mit einem Lagerauge eines dem Feststellarm tragenden Schwenklagerbolzens versehen ist. In this case there is a on the bearing base articulated bearing bracket about the vertical axis, the one with a bearing eye of the one holding the locking arm Pivot pin is provided.

Das in Fig.1 schaubildlich dargestellte Dreh-Kippfenster besitzt einen Festrahmen 1 und einen damit dreh-kippbeweglich über nicht dargestellte Mittel verbundenen Flügelrahmen 2, der oberseitig über eine herkömmliche Ausstellschere 10 mit dem Festrahmen 1 verbunden ist und dadurch in einer maximalen Kipp-öffnungsstellung gehalten werden kann. Die Betätigung des Dreh-Kippflügels und der in ihm untergebrachten Verbindungs- und Verschlußmittel erfolgt über den schwenkverstellbaren Handgriff 3. Zweckmäßig oberhalb dieses Handgriffs 3 ist der erfindungsgemäß beschaffene Flügelfeststeller 4 angeordnet, der im wesentlichen aus dem am Festrahmen 1 angeschlagenen Lagersockel 5, dem damit schwenkbeweglich verbundenen, um eine parallel zur Festrahmensebene liegende Drehachse ausschwenkbaren Feststellarm 6 und dem damit in wählbaren Feststelleingriff zu bringenden, am Flügelrahmen 2 befestigten, zapfenförmigen Feststellelement 7 besteht.The turn-tilt window shown in Fig. 1 has a fixed frame 1 and thus rotatable and tiltable sash frame 2 connected via means not shown, the on the upper side with a conventional scissor stay 10 with the Fixed frame 1 is connected and thereby in a maximum tilt-open position can be held. The actuation of the Turn and tilt wing and the connection housed in it and locking means is via the swivel-adjustable handle 3. Appropriately above this handle 3 is the invention procured wing lock 4 arranged in essentially from the bearing base attached to the fixed frame 1 5, the pivotally connected therewith about an axis of rotation lying parallel to the fixed frame plane swing-out locking arm 6 and thus in selectable locking engagement to be attached, attached to the sash 2, cone-shaped locking element 7.

Der den ausschwenkbaren Feststellarm 6 tragende Lagersokkel 5 besteht aus einer einfachen Lagerplatte 5, die über nur strichpunktiert angedeutete Verbindungsmittel, wie z.B. Feststellschrauben, auf dem Blendrahmen 1 flach aufliegend befestigt werden kann. Am Lagersockel 5 ist ein Schwenklagerauge 5' vorgesehen, das von den am Anlenkende 6' des Feststellarms vorhandenen gabelförmig vorspringenden Lageraugen 6'' umgriffen und damit über einen Schwenklagerbolzen 8 gelenkig verbunden ist.The bearing bracket supporting the swing-out locking arm 6 5 consists of a simple bearing plate 5 which over connecting means only indicated by dash-dotted lines, e.g. Locking screws, lying flat on the frame 1 can be attached. There is a swivel bearing eye on the bearing base 5 5 'provided that of the at the pivot end 6' of the locking arm existing fork-shaped projecting bearing eyes 6 '' and thus articulated via a pivot bearing pin 8 connected is.

Der Feststellarm 6 ist verhältnismäßig breit gehalten und mit einer mittig angeordneten Zahnleiste 9 versehen, deren Sperrzähne 9', wie Fig.4 zeigt, sich mindestens über die Hälfte der Breite des Feststellarmes 6 erstrecken. Entsprechend weit ragt auch der am Flügelrahmen 2 befestigte, das Feststellelement bildende einfache Feststellzapfen 7 seitlich in den Feststellarm 6 bzw. in dessen Zahnleiste 9 hinein, so daß sich ein entsprechend breiter Feststelleingriff ergibt. Oberhalb der Zahnleiste 9 ist eine Verschiebebahn 11 für den Feststellzapfen 7 vorgesehen, die durch die äquidistant zur Zahnleiste 9 verlaufende Abdeckleiste 12 abgedeckt ist. Die Abdeckleiste 12 ragt mit ihrem freien Ende 12' bis nahe an das Anlenkende 6' des Feststellarms 6 heran, wobei zwischen letzteren ein beidendig freier Durchtrittsschlitz 13 für den Feststellzapfen 7 vorhanden ist. Während der Feststellarm 6 eine an den Festrahmen 1 anzulegende flache Anlagefläche 6''' aufweist, velaufen seine Zahnleiste 9, die darüber gelegene Verschiebebahn 11 für den Feststellzapfen 7 und die mit dem Durchtrittsschlitz 13 versehene Abdeckleiste 12 leicht bogenförmig gekrümmt. An seinem dem Schwenklagerende 6' gegenüberliegenden Betätigungsende 6IV ist der Feststellarm 6 oberseitig noch mit quer verlaufenden, seine Griffigkeit erhöhenden Haftrippen 6V versehen.The locking arm 6 is kept relatively wide and provided with a centrally arranged toothed rack 9, the locking teeth 9 'of which, as shown in FIG. 4, extend at least over half the width of the locking arm 6. Correspondingly, the simple locking pin 7 attached to the sash frame 2 and forming the locking element projects laterally into the locking arm 6 or into its toothed rack 9, so that there is a correspondingly wide locking engagement. Above the toothed bar 9, a sliding track 11 is provided for the locking pin 7, which is covered by the cover bar 12 which extends equidistantly from the toothed bar 9. The cover strip 12 projects with its free end 12 'up to close to the articulation end 6' of the locking arm 6, a free passage slot 13 being provided at both ends for the locking pin 7 between the latter. While the locking arm 6 has a flat contact surface 6 '''to be attached to the fixed frame 1, its toothed strip 9, the sliding track 11 located above it for the locking pin 7 and the cover strip 12 provided with the passage slot 13 are slightly curved. At its actuating end 6 IV opposite the pivot bearing end 6 ', the locking arm 6 is also provided on the upper side with transverse adhesive ribs 6 V which increase its grip.

Die Zahnleiste 9 wird von der mit dem Durchtrittsschlitz 13 versehenen Abdeckleiste 12 beidseitig freiliegend abgedeckt, wobei der Feststellzapfen 7 mit seinem freien Zapfenende 7' entweder von links oder von rechts in die Verschiebebahn 11 bzw. zwischen zwei benachbarte Sperrzähne 9' des Feststellarms 6 hineinragt. The rack 9 is the one with the passage slot 13 provided cover strip 12 covered exposed on both sides, the locking pin 7 with its free pin end 7 'either from the left or from the right into the sliding track 11 or between two adjacent ratchet teeth 9 'of Locking arm 6 protrudes.

Zwischen dem vorzugsweise aus Metall-Druckguß bestehenden Feststellarm 6 und seinem materialmäßig entsprechend beschaffenen Lagersockel 5 ist eine schenkelförmige Blattfeder 14 angeordnet, die den Feststellarm 6 in die in Fig.5 dargestellte Ausschwenkstellung zu drücken sucht.Between the preferably made of die-cast metal Locking arm 6 and its material accordingly procured Bearing base 5 is a leg-shaped leaf spring 14 arranged, the locking arm 6 in that shown in Figure 5 Seeks to press the swivel position.

In der in Fig.2 dargestellten Schließstellung des am Festrahmen 1 anliegenden Flügelrahmens 2 wird durch den an letzterem befestigten Feststellzapfen 7 der ausschwenkbare Feststellarm 6 mit seiner planen Auflagefläche 6"' gegen den Festrahmen 1 gedrückt. Soll aus dieser Schließposition der Flügel 2 in eine in Fig.1 oder 3 dargestellte Kippöffnungsstellung gebracht werden, so braucht dazu lediglich der Griff 3 entsprechend betätigt zu werden. Das Kippöffnen des Flügels hat zur Folge, daß sein Feststellzapfen 7 eine entsprechende Schwenkbewegung vollführt und dieser dadurch den Feststellarm 6 für sein unter dem Einfluß der an ihm angreifenden Blattfeder 5 erfolgendes Ausschwenken freigibt. Der Feststellzapfen 7 und die Lage der Abdeckleiste 12 bzw. ihres Durchtrittsschlitzes 13 sind so aufeinander abgestimmt, daß bei dem Kippöffnen des Flügels und dem gleichzeitigen Ausschwenken des Feststellarmes 6 der Feststellzapfen 7 durch Anschlag an das freie Ende 12' der Abdeckleiste 12 selbsttätig in die oberhalb der Zahnleiste 9 gelegene Verschiebebahn 11 einfährt. Zum eigentlichen Feststellen des Flügels ist dann lediglich noch ein kurzes Andrücken des Armes 6 bzw. seiner Zahnleiste 9 gegen den Feststellzapfen 7 notwendig, der dann in die gewünschte, zwischen zwei benachbarten Sperrzähnen 9' gelegene Zahnlücke 9'' unter Überwindung eines entsprechenden Klemmwiderstandes einfährt. Die Sperrzähne 9' übergreifen nämlich die zwischen ihnen liegenden, durchmessermäßig dem Feststellzapfen 7 angepaßten Zahnlücken 9'' so weit, daß sie dem Ein- und Ausfahren des Feststellzapfens in bzw. aus einer Zahnlücke 9'' einen entsprechenden leichten Klemmwiderstand entgegensetzen. Dadurch wird der Flügel 2 in der in Fig.1 oder 3 dargestellten gewünschten Kippöffnungsposition sicher arretiert. Ein unbefugtes, von außen versuchtes Aushebeln des Feststellarmes ist nicht möglich. Zwar könnte dadurch der Feststellarm 6 unter Überwindung des Klemmwiderstandes vom Feststellzapfen 7 heruntergedrückt und letzterer somit in die Verschiebebahn 11 des Feststellarms 6 gebracht werden. Damit jedoch der Feststellzapfen 7 aus dem Durchtrittsschlitz 13 austreten könnte, müßte in jedem Falle der Flügel 2 zunächst wieder in seine Schließstellung gebracht werden. Soll dagegen der Flügel aus seiner Schließstellung in eine Drehöffnungsposition gebracht werden, so braucht dazu der Feststellarm 6 beim beginnenden Drehöffnen des Flügels lediglich gegen den Festrahmen 1 gedrückt zu werden, so daß dann der Feststellzapfen 7 durch den Durchtrittsschlitz 13 ausfahren kann, während der Feststellarm 6 danach unter dem Einfluß der angreifenden Blattfeder 5 wieder in seine Ausschwenkposition gelangt, wie das in Fig.5 dargestellt ist.In the closed position shown in Figure 2 on Fixed frame 1 adjacent sash 2 is by the the latter fixed locking pin 7 of the swing-out Locking arm 6 with its flat contact surface 6 "'against the Fixed frame 1 pressed. From this closed position the Wing 2 in a tilt opening position shown in Fig.1 or 3 brought, so only the handle needs 3 to be operated accordingly. The opening of the wing has the consequence that its locking pin 7 a corresponding Swiveling movement and this thereby the locking arm 6 for his under the influence of the leaf spring attacking him 5 swings out released. The locking pin 7 and the position of the cover strip 12 or its passage slot 13 are coordinated so that the Tilt opening the wing and swinging out at the same time the locking arm 6 of the locking pin 7 by stop the free end 12 'of the cover strip 12 automatically into the Moving track 11 located above the rack 9. The only way to actually determine the wing is then a short press on the arm 6 or his Toothed rack 9 against the locking pin 7 necessary, then into the desired, between two adjacent ratchet teeth 9 ' located tooth gap 9 '' while overcoming a corresponding one Retraction resistance retracts. Overlap the ratchet teeth 9 ' namely those between them, in terms of diameter Locking pin 7 adapted tooth spaces 9 '' so far that they the retraction and extension of the locking pin in or out of a Tooth gap 9 '' a corresponding slight clamping resistance oppose. As a result, the wing 2 in the in Fig.1 or 3 desired tilt opening position shown safely locked. An unauthorized, outside attempted pry out Locking arm is not possible. Although this could Locking arm 6 by overcoming the clamping resistance from Locking pin 7 pressed down and the latter thus in the Transfer path 11 of the locking arm 6 are brought. In order to however, the locking pin 7 from the passage slot 13 could emerge, the wing 2 would have to first in any case be brought back into its closed position. Should against it the wing from its closed position to a rotary opening position the locking arm 6 when the wing begins to open only against the Fixed frame 1 to be pressed, so that then the locking pin 7 can extend through the slot 13 while the locking arm 6 thereafter under the influence of the attacking Leaf spring 5 has returned to its swiveled-out position, as shown in Fig.5.

Der in den Fig.6 und 7 dargestellte Flügelfeststeller stimmt mit dem vorstehend beschriebenen weitestgehend überein. Seine übereinstimmenden Teile sind durch die entsprechenden Bezugszeichen markiert. Zusätzlich ist hier aber der Feststellarm 6 am Lagersockel 5 auch um eine parallel zur Festrahmenebene und senkrecht zur Drehachse des Feststellarmes 6 liegende Achse 15 drehbeweglich angelenkt, um mit diesem Flügelfeststeller die Flügel von Fenster oder Türen auch in verschiedenen begrenzten Drehöffnungspositionen feststellen zu können. Zu diesem Zweck ist am Lagersockel 5 ein um die senkrecht zur Drehachse des Feststellarmes 6 liegende Achse 15 drehbeweglicher Lagerbügel 16 angelenkt, der seinerseits mit einem Lagerauge 17 für die Aufnahme des den Feststellarm 6 tragenden Schwenklagerbolzens 8 versehen ist.The wing lock shown in Figures 6 and 7 largely corresponds to that described above. Its matching parts are through the corresponding ones Marked reference number. In addition, here is the Locking arm 6 on the bearing base 5 also about an axis lying parallel to the fixed frame plane and perpendicular to the axis of rotation of the locking arm 6 15 pivotally articulated to with this wing lock the wings of windows or doors also in various limited To be able to determine the opening positions. To For this purpose, there is an axis on the bearing base 5 about the axis perpendicular to the axis of rotation of the locking arm 6 15 pivotable bearing bracket 16 articulated, which in turn with a bearing eye 17 for receiving the locking arm 6 carrying pivot bearing pin 8 is provided.

Weiterhin unterscheidet sich dieser Flügelfeststeller von dem eingangs beschriebenen noch insoweit, als hier am freien Ende seines Feststellzapfens 7 ein Anschlagbund 7'' vorgesehen ist, der in den Sperrstellungen des Feststellzapfens 7 jeweils hinter die entsprechenden Sperrzähne 9' der Zahnleiste 9 greift. Dieser Anschlagbund 7'' kann auch anders als zylindrisch ausgebildet, beispielsweise ballig oder auch kegelförmig beschaffen sein. Hierdurch wird sichergestellt, daß in den begrenzten Flügelöffnungspositionen der Feststellarm 6 nicht seitlich über den Feststellzapfen 7 weggedrückt werden kann, was andernfalls bei einem unbefugten Einbruchs- bzw. Einstiegversuch noch unter Umständen möglich wäre. Dieser zusätzlichen Einbruchssicherung dient auch die auf der der Zahnleiste 9 zugewandten Innenseite der Abdeckleiste 12 angeordnete, zur Zahnleiste 9 äquidistant verlaufende Sperrleiste 18, die von dem Anschlagbund 7'' des Feststellzapfens 7 in dessen jeweiligen in der Verschiebebahn 11 gelegenen Verschiebe- oder Aushebepositionen hintergriffen wird. Dadurch wird auch in diesen Fällen eine zusätzliche Axialsicherung zwischen Feststellzapfen 7 und Feststellarm 6 sichergestellt.This wing lock also differs of the above-described to the extent that here on free end of its locking pin 7 a stop collar 7 '' is provided in the locking positions of the locking pin 7 each behind the corresponding ratchet teeth 9 ' Rack 9 engages. This stop collar 7 '' can also be different as cylindrical, for example crowned or also be conical. This ensures that in the limited wing opening positions of the locking arm 6 not pushed laterally over the locking pin 7 what can otherwise be the case of an unauthorized intrusion or attempted entry would still be possible under certain circumstances. This the burglar alarm also serves as an additional burglar alarm the inside of the cover strip 12 facing the toothed strip 9 arranged locking bar extending equidistantly from the toothed bar 9 18 by the stop collar 7 '' of the locking pin 7 in its respective located in the sliding path 11 Moving or lifting positions is engaged. Thereby an additional axial lock is also used in these cases ensured between locking pin 7 and locking arm 6.

Der neue Flügelfeststeller ist nicht auf die dargestellte Anwendungsweise bei Dreh-Kippfenstern bzw. -türen beschränkt. Vielmehr kann er auch bei einfachen Drehfenstern oder Kippfenstern, etwa Keller-Oberlichtfenstern zur Flügelarretierung in begrenzten unterschiedlichen Öffnungsstellungen vorteilhaft verwendet werden. Dabei können der Feststellarm grundsätzlich auch am Flügelrahmen und das damit in Feststelleingriff zu bringende Feststellelement am Festrahmen angeschlagen werden, was etwa bei nach außen öffnenden Flügeln vorteilhaft wäre. Weiterhin besteht grundsätzlich auch die Möglichkeit, den neuen Flügelfeststeller nicht wie dargestellt unbedingt auf der Öffnungsseite des Dreh-Kippfensterflügels, sondern ihn auf dessen Bandseite anzuordnen. Die in Fig.1 dargestellte Anordnung des Flügelfeststellers oberhalb des Fensterflügelbetätigungsgriffs bietet den Vorteil, daß der Feststeller von Kindern nur schwer oder gar nicht erreichbar ist, mithin ein unbefugtes, gefahrvolles Öffnen des Fensterflügels ausgeschlossen wird.The new wing lock is not on the one shown Limited use for turn and tilt windows or doors. Rather, it can also be used with simple rotating windows or bottom hung windows, such as basement skylight windows for wing locking in limited different opening positions can be used advantageously. The locking arm basically also on the casement and thus in locking engagement Locking element to be brought attached to the fixed frame be what about wings opening outwards would be beneficial. In principle, there is also the Possibility of the new wing stay not as shown absolutely on the opening side of the tilt and turn window sash, but to place it on the band side. In the Fig.1 arrangement of the wing lock shown above the window sash operating handle has the advantage that the lock is difficult or impossible to reach for children is, therefore, an unauthorized, dangerous opening of the Window sash is excluded.
