Abstract

The snap-lock device (9) is used as a covered auxiliary lock for windows (2) and doors which can move about a hinge axis (3) relative to a fixed frame (1). The latter is on or near a boundary edge, and the lock has a spring-loaded latch (12) which can slide in a housing, but which cannot rotate relative to it. The latch is mounted in a housing pot (11) which sits in the circumferential surface (6) of the swinging door or window adjacent to the air-gap, and engages against an element (13) which is fastened to the fixed frame. Both the element and the latch work in combination over a circular arc (4), using wedge surfaces (26,27) which from tangents to the hinge axis. The end (17) of the latch which is guided in the pot has a similar open pot shape, in order to form a receptacle (18) for the spring (10) which is supported at the base (15) of the housing pot.

Description

Die Erfindung betrifft eine Schnappriegelvorrichtung als verdeckten Zusatzverschluß, insbesondere Mittelverschluß, für Flügel von Fenstern, Türen od. dgl., die um eine an oder nahe einer Begrenzungskante gelegene Gelenkachse beweglich an einem Blendrahmen gelagert ist. Gegenstand der Erfindung ist dabei insbesondere eine Schnappriegelvorrichtung mit einer durch eine Feder unter Vorspannung gehaltenen, in einem Gehäuse drehfest, aber axial verschieblich geführten Riegelfalle und mit einem Rastelement, welches das Gegenlager für die Riegelfalle bildet.The invention relates to a snap lock device as a concealed additional lock, in particular a central lock for sashes of windows, doors or the like, which is movably mounted on a frame on a hinge axis located at or near a boundary edge. The object of the invention is in particular a snap lock device with a bolt latch held in place by a spring and non-rotatably but axially displaceably guided in a housing and with a locking element which forms the counter bearing for the bolt latch.

Für Flügel von Fenstern, Türen od. dgl., die um eine an oder nahe einer Begrenzungskante gelegene Gelenkachse beweglich an einem Blendrahmen gelagert sind, also für Fenster und Türen mit Drehflügel, Kippflügel oder Klappflügel werden bisher verdeckte Zusatzverschlüsse, insbesondere sogenannten Mittelverschlüsse, verwendet, bei denen ein flügelseitig befestigtes Verschlußteil und ein blendrahmenseitig befestigtes Verschlußteil sich mit jeweils ortsfest bzw. starr daran montierten Keilen beim Einschwenken des Flügels in die Schließlage hintergreifen (vgl. DE 24 49 176 B und DE 28 45 938 A1). Dabei sind die zusammenwirkenden Funktionsteile jeweils an der Falzumfangsfläche von Flügel und Blendrahmen starr befestigt und so gestaltet, daß sie den Abstand zwischen diesen - den sogenannten Falzluftbereich - voll ausfüllen bzw. überbrücken sowie sich dabei abschnittweise gegenseitig hintergreifen können.For sashes of windows, doors or the like, which are movably mounted on a frame around a hinge axis located at or near a boundary edge, i.e. for windows and doors with rotating sashes, tilting sashes or folding sashes, previously hidden additional locks, in particular so-called center locks, are used, in which a closure part fastened on the wing side and a closure part fastened on the frame side engage behind each other with wedges fixed or rigidly mounted thereon when the wing is pivoted into the closed position (cf. DE 24 49 176 B and DE 28 45 938 A1). The interacting functional parts are each rigidly attached to the peripheral circumferential surface of the sash and frame and designed so that they the distance between these - the so-called rebate air area - fill in or bridge completely and can reach behind each other in sections.

Die praktische Erfahrung hat gezeigt, daß diese bekannten Zusatzverschlüsse, insbesondere Mittelverschlüsse, nur ordnungsgemäß funktionieren, wenn und solange ein ganz bestimmter Abstand zwischen den einander zugewendeten Falzumfangsflächen von Flügel und Blendrahmen - der sogenannte Falzluftabstand - exakt eingehalten wird. Da aber diese Bedingung nur in den wenigsten Fälle auf Dauer erfüllt wird, ist die den Zusatzverschlüssen, insbesondere Mittelverschlüssen, zugedachte Anpreßwirkung tatsächlich nicht oder zumindest nur mangelhaft erreichbar.Practical experience has shown that these known additional closures, in particular center closures, only function properly if and for as long as a certain distance between the facing peripheral circumferential surfaces of the sash and frame - the so-called rebate clearance - is observed exactly. However, since this condition is only met in the long term in the rarest of cases, the contact pressure intended for the additional closures, in particular center closures, cannot actually be achieved, or at least only with difficulty.

Die Erfindung zielt deshalb auf die Beseitigung dieser Mängel ab. Es liegt ihr demnach die Aufgabe zugrunde, einen Zusatzverschluß, insbesondere Mittelverschluß für Fenster, Türen od. dgl. anzugeben, bei denen der Flügel um eine an oder nahe einer Begrenzungskante gelegene Gelenkachse beweglich (drehbar, kippbar oder klappbar) am Blendrahmen gelagert ist und dabei die Möglichkeit einer Abstandsänderung seiner Falzumfangsflächen von den Falzumfangsflächen des Blendrahmens aufgrund gewollter oder ungewollter Flügelverlagerungen besteht. Dabei kommt es darauf an, daß die auftretenden Änderungen der Falzluftabstände vom Zusatzverschluß, insbesondere Mittelverschluß völlig selbsttätig, bzw. automatisch und damit dauerhaft funktionssicher ausgeglichen werden.The invention therefore aims to remedy these shortcomings. It is therefore an object of the invention to provide an additional lock, in particular a central lock for windows, doors or the like, in which the sash is mounted on the frame and thereby movable (rotatable, tiltable or foldable) about a hinge axis located at or near a boundary edge there is the possibility of a change in the distance of its fold peripheral surfaces from the fold peripheral surfaces of the frame due to intentional or unwanted wing displacements. It is important that the changes occurring in the clearance of the clearance air from the additional lock, in particular the central lock, are compensated completely automatically or automatically and thus permanently and reliably.

Zur Lösung dieser Aufgabe benutzt die Erfindung als verdeckten Zusatzverschluß, insbesondere Mittelverschluß, deshalb eine Schnappriegelvorrichtung mit einer durch eine Feder unter Vorspannung gehaltenen, in einem Gehäuse drehfest, aber axial verschieblich geführten Riegelfalle und mit einem Rastelement, welches das Gegenlager für die Riegelfalle bildet.To achieve this object, the invention uses as a concealed additional lock, in particular a central lock, therefore a snap lock device with a spring latch that is held in a housing under tension, rotatably but axially displaceably guided, and with a latching element, which forms the counter bearing for the latch bolt.

Erfindungsgemäß zeichnet sich diese Schnappriegelvorrichtung dabei besonders dadurch aus, daß die Riegelfalle in einem in der Falzumfangsfläche des Flügels sitzenden Gehäusetopf gelagert ist, daß die Riegelfalle mit dem am Blendrahmen befestigten Rastelement über einen Kreisbogen um die Flügel-Gelenkachse tangierende Schräg- bzw. Keilflächen zusammenwirkt und daß die Riegelfalle an ihrem im Gehäusetopf geführten Ende ebenfalls topfartig offen ausgeführt ist, um auch dort eine Aufnahme für die im Gehäusetopf bodenseitig abgestützte Feder auszubilden.According to the invention, this snap lock device is particularly characterized in that the locking latch is mounted in a housing pot seated in the rebate peripheral surface of the wing, that the locking latch interacts with the locking element attached to the frame via an arc tangent to the wing hinge axis and oblique or wedge surfaces that the bolt latch is also designed like a pot at its end guided in the housing pot, in order to form a receptacle there for the spring supported in the housing pot on the bottom.

Vorteilhaft bei einer erfindungsgemäßen Schnappriegelvorrichtung mit diesen Merkmalen ist, daß für die Unterbringung ihrer Funktionsteile zwischen Flügel- und Blendrahmen nur ein geringfügig größerer Einbauraum benötigt wird, als für die Zusatzverschlüsse, insbesondere Mittelverschlüsse der vorstehend angegebenen bekannten Bauart, daß dafür aber ihre Funktionssicherheit bei variierenden Falzluftmaßen dauerhaft gewährleistet bleibt.
Vorteilhaft ist aber auch, daß sich die Schnappriegelvorrichtung an Flügel und Blendrahmen der Fenster, Türen od. dgl. mit nur geringem Arbeitsaufwand anbringen läßt, weil als Aufnahmen für ihre Funktionsteile lediglich einfache Bohrungen von relativ geringer Tiefe benötigt werden, sofern hierfür nicht schon sowieso vorhandene Profilnuten, insbesondere Beschlagnuten, an den Falzumfangsflächen von Flügel- und Blendrahmen genutzt werden können.
An advantage of a snap-lock device according to the invention with these features is that only a slightly larger installation space is required for accommodating their functional parts between the sash and frame than for the additional locks, in particular center locks of the known type specified above, but that their functional reliability with varying clearance dimensions remains permanently guaranteed.
However, it is also advantageous that the snap-lock device can be attached to the sash and frame of the windows, doors or the like with only a small amount of work, because only simple bores of relatively shallow depth are required as receptacles for their functional parts, provided that these are not already present anyway Profile grooves, especially fitting grooves, can be used on the rebate peripheral surfaces of sash and frame.

Die Erfindung sieht in weiterer Ausgestaltung der Schnappriegelvorrichtung vor, daß der Verschiebeweg der Riegelfalle im Gehäusetopf durch einen kolbenartigen Bolzen begrenzt ist, daß dieser Bolzen mit seinem Kolbenkopf in einen zur Schräg- bzw. Keilfläche der Riegelfalle hin offenen Kanal eingreift sowie mit seinem Schaft das im Gehäusetopf geführte Ende der Riegelfalle und auch die als Druckfeder ausgebildete Feder koaxial durchsetzt, und daß der Bolzen mit seinem Schaft am Boden des Gehäusetopfes festgelegt, z.B. vernietet oder verschraubt ist, während sein Kolbenkopf einen Anschlag für eine den Kanal gegen das topfartig offene Ende abgrenzende Wand der Riegelfalle bildet.The invention provides in a further embodiment of the snap lock device that the displacement of the bolt latch in the housing pot is limited by a piston-like bolt, that this bolt engages with its piston head in a channel open to the oblique or wedge surface of the bolt latch and with its shaft that in End of the bolt latch and the spring designed as a compression spring coaxially pass through the housing pot, and that the bolt is fixed, for example riveted or screwed, to the bottom of the housing pot with its shaft. while its piston head forms a stop for a wall of the bolt latch delimiting the channel against the pot-like open end.

Von Vorteil ist auch, daß der Gehäusetopf mit einem von seinem Außenumfang quer zu seiner Längsachse abstehenden Anschlag oder Kragen versehen ist, der seine Einbautiefe in das Flügelprofil begrenzt, also für eine optimale Grundausrichtung der zusammenwirkenden Funktionsteile an den Falzumfangsflächen von Flügel- und Blendrahmen sorgt.It is also advantageous that the housing pot is provided with a stop or collar projecting from its outer circumference transversely to its longitudinal axis, which limits its installation depth in the sash profile, that is to say ensures an optimal basic alignment of the interacting functional parts on the rebate peripheral surfaces of the sash and frame.

Als empfehlenswert hat es sich nach der Erfindung auch erwiesen, den Gehäusetopf mit einem über den Anschlag oder Kragen in Richtung der Längsachse vorstehenden und in den Falzluftbereich zwischen Flügel- und Blendrahmen hineinragenden Abschnitt zu versehen, weil hierdurch für eine optimale Führung der Riegelfalle im Gehäusetopf der in jedem Falle zur Verfügung stehende minimale Falzluftabstand zwischen Flügel- und Blendrahmen genutzt werden kann.It has also proven to be advisable according to the invention to provide the housing pot with a section projecting beyond the stop or collar in the direction of the longitudinal axis and projecting into the rebate air area between the sash and frame, because in this way the latch bolt is optimally guided in the housing pot in any case, available minimum clearance between the sash and frame can be used.

Wenn mindestens der hinter dem Anschlag oder Kragen gelegene Abschnitt des Gehäusetopfes zylindrische Gestalt hat und einen Außendurchmesser von höchstens 12 mm aufweist, dann kann der die Riegelfalle enthaltende Funktionsteil der Schnappriegelvorrichtung nicht nur auf einfache Weise in eine üblicherweise an der Falzumfangsfläche des Flügelrahmenprofils vorgesehene, abgestufte Beschlagnut (sogenannten Euronut) eingesetzt werden. Vielmehr ist es auch möglich, an nicht von vornherein mit einer solchen Beschlagnut ausgestatteten Flügelholmen eine einfache Bohrung von 12 mm Durchmesser als Aufnahme anzubringen.If at least the section of the housing pot located behind the stop or collar has a cylindrical shape and has an outer diameter of at most 12 mm, then the functional part of the snap-lock device containing the latch latch can not only be simply inserted into a stepped fitting groove that is usually provided on the circumferential groove surface of the sash profile (so-called Euronut) can be used. Rather, it is also possible to make a simple bore of 12 mm in diameter as a receptacle on wing spars not equipped with such a fitting groove from the outset.

Für eine optimale Funktion der Schnappriegelvorrichtung im Bereich der Gelenkachse zwischen Flügel- und Blendrahmen hat es sich weiterhin als wichtig erwiesen, daß die Schräg- oder Keilflächen von Riegelfalle und Rastelement eine Neigung von weniger als 45°, vorzugsweise zwischen 25° und 35°, zur Verschlußebene des Fensters oder der Tür aufweisen und daß dabei ihre einander zugewendeten, freien Enden, jeweils mit einer vom Kreisbogen um die Flügel-Gelenkachse wegführende Abrundung oder Anfasung versehen sind. Insbesondere bei der Schließbewegung des Flügels um die Gelenkachse wird durch diese Maßnahmen das ordnungsgemäße Zusammenführen der Schräg- bzw. Keilfläche der Riegelfalle mit der Schräg- bzw. Keilfläche des Rastelementes gewährleistet.For optimal functioning of the snap lock device in the area of the hinge axis between the sash and frame, it has also proven to be important that the inclined or wedge surfaces of the latch and latch element have an inclination of less than 45 °, preferably between 25 ° and 35 ° Have the level of closure of the window or door and that their facing each other, free ends, each with a rounding or chamfer leading away from the circular arc around the wing-joint axis. In particular during the closing movement of the wing about the hinge axis, these measures ensure the correct merging of the inclined or wedge surface of the locking latch with the inclined or wedge surface of the latching element.

Vorteilhaft ist es auch, das Rastelement als topfartiges Formteil zu gestalten und mit einem quer zu seiner Längsachse gerichteten Anschlagkragen zu versehen, damit es sich am Blendrahmen ebenfalls in eine zur Falzumfangsfläche hin ausmündende einfache Bohrung eintreiben läßt.It is also advantageous to design the locking element as a pot-like molded part and to provide it with a stop collar directed transversely to its longitudinal axis, so that it can also be driven into the frame into a simple bore opening towards the circumferential surface of the fold.

Erwähnenswert ist schließlich noch, daß die die Riegelfalle im Gehäusetopf axial abstützende Druckfeder von einer Schraubenfeder, von einer Tellerfedersäule, von einer Elastomerhülse oder auch von einem Verbundelement dieser verschiedener Federarten gebildet werden kann und daß sich der Gehäusetopf, die Riegelfalle und das Rastelement als Spritzguß-Formteile aus Kunststoff und/oder als Druckguß-Formteile aus Metall (Zink- oder Messinglegierungen) ausführen lassen.Finally, it is worth mentioning that the compression spring axially supporting the latch latch in the housing pot can be formed by a helical spring, by a plate spring column, by an elastomer sleeve or also by a composite element of these different types of spring and that the housing pot, the latch latch and the latching element are injection molded. Have molded parts made of plastic and / or die-cast molded parts made of metal (zinc or brass alloys).

In Fig. 1 der Zeichnung ist von einem Kunststoff-Fenster ein Querschnitts-Profilteilstück eines Blendrahmens 1 und auch ein Querschnitts-Teilstück eines Flügels 2 zu sehen. Zugleich ist dort auch angedeutet, daß der Flügel 2 relativ zum Blendrahmen 1 um eine nahe einer Begrenzungskante liegende Gelenkachse 3 beweglich gelagert sein soll. Die die Gelenkachse 3 definierenden Gelenkbeschläge (Scharniere) sind jedoch - der Einfachheit halber - nicht zu sehen. Angedeutet ist in Fig. 1 jedoch ein Kreisbogen 4, dessen Zentrum mit der Gelenkachse 3 Deckungslage hat und der eine Bewegungsbahn des Flügels 2 kennzeichnet, welche dieser bei seiner Öffnungs- und Schließbewegung relativ zum Blendrahmen um die Gelenkachse 3 durchläuft.In Fig. 1 of the drawing is a cross-sectional profile section of a frame 1 and also a plastic window Cross section of a wing 2 can be seen. At the same time, it is also indicated that the wing 2 should be mounted so that it can move relative to the frame 1 about an articulation axis 3 close to a boundary edge. However, for the sake of simplicity, the hinge fittings defining the hinge axis 3 cannot be seen. However, an arc 4 is indicated in FIG. 1, the center of which has a cover position with the hinge axis 3 and which characterizes a movement path of the wing 2, which the wing traverses about the hinge axis 3 during its opening and closing movement relative to the frame.

Der Blendrahmen 1 weist eine Falzumfangsfläche 5 auf, während der Flügel 2 eine Falzumfangsfläche 6 hat.The frame 1 has a rebate peripheral surface 5, while the sash 2 has a rebate peripheral surface 6.

Die Falzumfangsfläche 5 des Blendrahmens 1 erstreckt sich quer zu dessen Hauptebene und auch die Falzumfangsfläche 6 des Flügels 2 ist quer zu dessen Hauptebene orientiert. Bei in Schließlage relativ zum Blendrabmen 1 gebrachtem Flügel 2 erstrecken sich deren Hauptebenen parallel zueinander und auch die jeweils quer dazu gerichteten Falzumfangsflächen 5 und 6 sind dann im wesentlichen parallel zueinander orientiert. Sie nehmen dabei einen Abstand 7 - den sogenannten Falzluftabstand - voneinander ein, der normalerweise einem vorgegebenen Maß entsprechen soll, welcher jedoch im praktischen Einsatz der Fenster und Türen od. dgl. aus verschiedenen Gründen differieren, nämlich sowohl größer als auch kleiner als das vorgegebene Maß werden kann.The fold circumferential surface 5 of the frame 1 extends transversely to its main plane and also the fold circumferential surface 6 of the wing 2 is oriented transversely to its main plane. When the wing 2 is brought into the closed position relative to the blind frame 1, its main planes extend parallel to one another and the fold circumferential surfaces 5 and 6 directed transversely thereto are then oriented essentially parallel to one another. They are at a distance 7 - the so-called rebate clearance - from each other, which should normally correspond to a predetermined dimension, but which differ in practical use of the windows and doors or the like for various reasons, namely both larger and smaller than the predetermined dimension can be.

Zwischen den der Gelenkachse 3 benachbarten Holmen von Blendrahmen 1 und Flügel 2 ist im Bereich der Falzumfangsflächen 5 und 6, also bei geschlossenem Fenster bzw. geschlossener Tür verdeckt, mindestens ein Zusatzverschluß 8 als sogenannter Mittelverschluß angeordnet. Dieser ist als Schnappriegelvorrichtung 9 ausgeführt, welche mit einer durch eine Feder 10 unter Vorspannung gehaltenen und in einem Gehäuse 11 drehfest, aber axial verschieblich geführten Riegelfalle 12 arbeitet und darüber hinaus als Gegenlager für die Riegelfalle 12 ein Rastelement 13 umfaßt.At least one additional closure 8 is arranged as a so-called center closure between the spars of the frame 1 and sash 2 adjacent to the hinge axis 3 in the area of the fold peripheral surfaces 5 and 6, that is to say when the window or door is closed. This is designed as a snap lock device 9, which works with a locking latch 12 held by a spring 10 under tension and rotatably but axially displaceably guided in a housing 11 and also comprises a latching element 13 as a counter-bearing for the locking latch 12.

Das Gehäuse 11 hat die Form eines zumindest an seinem Außenumfang im wesentlichen zylindrischen Gehäusetopfes, welcher über einen Teil seiner Länge in eine an der Falzumfangsfläche 6 des Flügels 2 befindliche Vertiefung eingesenkt ist, welche im Falle der Fig. 1 die Form einer Stufennut 14 hat, wie sie üblicherweise zur Aufnahme bzw. Unterbringung von Treibstangenbeschlägen dient.The housing 11 has the shape of an essentially cylindrical housing pot, at least on its outer circumference, which is recessed over part of its length into a recess located on the circumferential surface 6 of the wing 2, which has the shape of a step groove 14 in the case of FIG. 1, as it usually serves to accommodate or accommodate espagnolette fittings.

An seinem innerhalb der Stufennut 14 gelegenen Ende weist das Gehäuse 11 bzw. der Gehäusetopf einen Boden 15 auf, während das diesem gegenüberliegende Ende der Topfhöhlung 16 offen ist. In die Topfhöhlung 16 des Gehäuses 11 bzw. des Gehäusetopfes ragt die Riegelfalle 12 der Schnappriegelvorrichtung 9 mit ihrem ebenfalls topfartig offen ausgeführten Ende 17 hinein und wird dadurch sicher axial verschiebbar geführt. In die Aufnahme 18 des topfartig offenen Endes der Riegelfalle 12 ragt die als Schraubendruckfeder ausgeführte Feder 10 hinein, wobei sie sich einerseits am Boden 15 des Gehäuses 11 bzw. Gehäusetopfes abstützt und andererseits auf eine die Aufnahme 18 begrenzende Querwand 19 einwirkt, die einen relativ großen Abstand vom Ende 17 der Riegelfalle 12 hat. Dadurch kann die Druckfeder 10 mit einer relativ großen Baulänge Verwendung finden und folglich einen entsprechend großen Federweg aufweisen.At its end located within the step groove 14, the housing 11 or the housing pot has a bottom 15, while the end of the pot cavity 16 opposite this is open. The bolt latch 12 of the snap-lock device 9 projects into the pot cavity 16 of the housing 11 or of the housing pot with its end 17, which is likewise of a pot-like design, and is thereby guided so as to be axially displaceable. The spring 10, designed as a helical compression spring, projects into the receptacle 18 of the pot-like open end of the bolt latch 12, whereby it is supported on the one hand on the bottom 15 of the housing 11 or housing pot and on the other hand acts on a transverse wall 19 which delimits the receptacle 18 and which has a relatively large size Distance from the end 17 of the bolt latch 12 has. As a result, the compression spring 10 can be used with a relatively large overall length and consequently have a correspondingly large spring travel.

Der Auswärts-Verschiebeweg der Riegelfalle 12 relativ zum Gehäuse 11 bzw. Gehäusetopf wird durch einen kolbenartigen Bolzen 20 begrenzt, der mit seinem Kolbenkopf 21 in einen zum freien Ende der Riegelfalle 12 offenen Kanal 22 eingreift. Andererseits durchsetzt der Bolzen 20 mit seinem Schaft 23 nicht nur die Querwand 19 der Riegelfalle 12, sondern auch deren Aufnahme 18 über das Ende 17 hinaus. Dabei ist der Schaft 23 am Boden 15 des Gehäuses 11 bzw. Gehäusetopfes festgelegt, z. B. vernietet oder verschraubt. Der Schaft 23 des kolbenartigen Bolzens 20 ist koaxial auch von der Schraubendruckfeder 10 umgeben, so daß diese durch ihre Einwirkung auf die Querwand 19 die Riegelfalle 12 bis gegen den Kolbenkopf 21 unter elastischer Vorspannung zum Anschlag bringen kann.The outward displacement path of the latch bolt 12 relative to the housing 11 or the housing pot is limited by a piston-like bolt 20 which engages with its piston head 21 in a channel 22 open to the free end of the bolt latch 12. On the other hand, the bolt 20 penetrates not only the transverse wall 19 of the bolt latch 12 with its shank 23, but also its receptacle 18 beyond the end 17. The shaft 23 is fixed to the bottom 15 of the housing 11 or housing pot, for. B. riveted or screwed. The shaft 23 of the piston-like bolt 20 is also coaxially surrounded by the helical compression spring 10, so that this acts on the transverse wall 19, the bolt latch 12 to can stop against the piston head 21 under elastic prestress.

Erwähnt werden soll an dieser Stelle, daß die Feder 10 nicht notwendigerweise als Schraubendruckfeder ausgeführt werden muß. Sie kann vielmehr auch von einer Tellerfedersäule oder einer Elastomerhülse gebildet werden, die einerseits in die Aufnahme 18 der Riegelfalle 12 hineinragt und andererseits vom Schaft 23 des kolbenartigen Bolzens 20 durchsetzt wird. Selbstverständlich wäre als Feder 10 auch ein Verbundelement benutzbar, in dem mehrere der vorgenannten Federarten miteinander vereinigt sind.At this point it should be mentioned that the spring 10 does not necessarily have to be designed as a helical compression spring. Rather, it can also be formed by a plate spring column or an elastomer sleeve which, on the one hand, projects into the receptacle 18 of the locking latch 12 and, on the other hand, is penetrated by the shaft 23 of the piston-like bolt 20. Of course, a composite element could also be used as the spring 10, in which several of the aforementioned types of springs are combined with one another.

Das Gehäuse 11 der Schnappriegelvorrichtung 9 bzw. der Gehäusetopf weist an seinem Außenumfang einen quer zu seiner Längsachse abstehenden Anschlag oder Kragen 24 auf, der so angeordnet und ausgebildet ist, daß er die Einbautiefe für die Schnappriegelvorrichtung 9 in die Falzumfangsfläche 6 des Flügels begrenzt. Wenn es sich bei der Aufnahme in der Falzumfangsfläche 6 des Flügels 2 um eine Stufennut 14 handelt, wie das in Fig. 1 gezeigt wird, dann kann der Anschlag oder Kragen 24 als Platte ausgeführt werden, deren Breite an die größte Öffnungsweite der Stufennut 14 angepaßt ist. Die Länge der Platte kann von solcherThe housing 11 of the snap lock device 9 or the housing pot has on its outer circumference a stop or collar 24 projecting transversely to its longitudinal axis, which is arranged and designed such that it limits the installation depth for the snap lock device 9 in the rebate peripheral surface 6 of the wing. If the receptacle in the rebate peripheral surface 6 of the wing 2 is a step groove 14, as shown in FIG. 1, then the stop or collar 24 can be designed as a plate, the width of which is adapted to the greatest opening width of the step groove 14 is. The length of the plate can vary from such

Art sein, daß sich mindestens einseitig neben dem Gehäuse 11 bzw. dem Gehäusetopf noch Befestigungsschrauben anbringen lassen.Be of the kind that fastening screws can be attached at least on one side next to the housing 11 or the housing pot.

Das Gehäuse 11 bzw. der Gehäusetopf ist andererseits mit einem über den Anschlag oder Kragen 24 in Richtung der Längsachse vorstehenden und in den Falzluftbereich 7 wischen Flügel 2 und Blendrahmen 1 frei hineinragenden Längenabschnitt 25 versehen, um auf diese Art und Weise eine möglichst große Führungslänge für die Riegelfalle 12 zu erhalten. Wichtig ist dabei, daß der Längenabschnitt 25 den Anschlag oder Kragen 24 höchstens um ein Maß überragt, welches in jedem Falle wesentlich kleiner als der geringstmögliche Abstand 7 zwischen den Falzumfangsflächen 5 und 6 ausgeführt ist.The housing 11 or the housing pot, on the other hand, is provided with a length section 25 projecting beyond the stop or collar 24 in the direction of the longitudinal axis and wiping into the rebate air region 7, the wing 2 and the frame 1 in order in this way to achieve the longest possible guide length for to receive the bolt latch 12. It is important that the length section 25 projects beyond the stop or collar 24 at most by an amount which is in any case significantly smaller than the smallest possible distance 7 between the fold peripheral surfaces 5 and 6.

Wichtig ist bei dem Zusatzverschluß 8, insbesondere Mittelverschluß, noch daß die Riegelfalle 12 der Schnappriegelvorrichtung 9 an ihrem freien Ende eine Schräg- bzw. Keilfläche 26 aufweist, die mit einer Schräg- bzw. Keilfläche 27 am Rastelement 13 zusammenwirken kann. Dabei kommt es darauf an, daß beide Schräg- bzw. Keilflächen 26 und 27 relativ zueinander eine solche Lage haben, daß sie Kreisbögen, beispielsweise den Kreisbogen 4 um die Gelenkachse 3 zwischen Flügel 2 und Blendrahmen 1 tangieren bzw. tangieren können. Als zweckmäßig hat es sich erwiesen, wenn die Schräg- oder Keilflächen 26 und 27 von Riegelfalle 12 und Rastelement 13 jeweils eine Neigung von weniger als 45° zur Verschlußebene des Fensters oder der Tür aufweisen. Vorzugsweise sollte dabei ein Neigungswinkel gewählt werden, der zwischen 25° und 35° zur Verschlußebene des Fensters oder der Tür verläuft.It is important for the additional closure 8, in particular the center closure, that the latch 12 of the snap-lock device 9 has at its free end an inclined or wedge surface 26 which can cooperate with an inclined or wedge surface 27 on the locking element 13. It is important that both inclined or wedge surfaces 26 and 27 have such a position relative to one another that they can or can affect circular arcs, for example the circular arc 4 about the hinge axis 3 between the sash 2 and the frame 1. It has proven to be expedient if the inclined or wedge surfaces 26 and 27 of latch bolt 12 and locking element 13 each have an inclination of less than 45 ° to the locking plane of the window or door. Preferably, an angle of inclination should be selected that runs between 25 ° and 35 ° to the locking plane of the window or door.

Ein dauerhaft ordnungsgemäßes Zusammenwirken der Schräg- bzw. Keilflächen 26 und 27 von Riegelfalle 12 und Rastelement 13 wird auf einfache Weise dadurch gewährleistet, daß die einander zugewendeten, freien Enden der Schräg- bzw. Keilflächen 26 und 27 jeweils mit einer Abrundung oder Anfasung 28 und 29 versehen sind, die einen vom Kreisbogen 4 um die Flügel-Gelenkachse 3 wegführenden Verlauf hat.A permanent correct interaction of the inclined or wedge surfaces 26 and 27 of the latch 12 and locking element 13 is ensured in a simple manner that the facing free ends of the inclined or wedge surfaces 26 and 27 each with a rounding or chamfer 28 and 29 are provided, which has a course leading away from the circular arc 4 about the wing hinge axis 3.

Auch das Rastelemet 13 läßt sich dann mit einem geringen Arbeitsaufwand am Blendrahmen 1 befestigen, wenn es als topfartiges Formteil gestaltet und mit einem quer zu seiner Längsachse gerichteten Anschlagkragen 30 versehen ist.The locking element 13 can also be attached to the frame 1 with little effort if it is designed as a pot-like molded part and is provided with a stop collar 30 directed transversely to its longitudinal axis.

Das Gehäuse 11 bzw. der Gehäusetopf, die Riegelfalle 12 und das Rastelement 13 können als Spritzgruß-Formteile aus Kunststoff und/oder als Druckgruß-Formteile aus Metall (Zink- oder Messinglegierungen) ausgeführt werden.The housing 11 or the housing pot, the bolt latch 12 and the locking element 13 can be designed as injection molded parts made of plastic and / or as pressure molded parts made of metal (zinc or brass alloys).

In Fig. 2 der Zeichnung ist gezeigt, daß sich ein Zusatzverschluß 8, insbesondere Mittelverschluß in Form einer Schnappriegelvorrichtung 9 auch bei. Fenstern und Türen in Benutzung nehmen läßt, deren Blendrahmen 1 und Flügel 2 aus Holz gefertigt sind. Dort ist das Gehäuse 11 bzw. der Gehäusetopf der Schnappriegelvorrichtung 9 in eine zur Falzumfangsfläche 6 des Flügels ausmündende Bohrung 31 eingesetzt, während das Rastelement 13 von einer an der Falzumfangsfläche 5 des Blendrahmens 1 ausmündenden Bohrung 32 aufgenommen ist. In diesem Falle sind die Anschläge bzw. Kragen 24 und 30 zweckmäßigerweise nur einseitig vom Umfang des Gehäuses 11 bzw. Gehäusetopfes und des Rastelementes 13 abstehend vorgesehen und so gestaltet, daß sie auch als Ausrichtmittel und Verdrehsicherungen mit dem Blendrahmen 1 und dem Flügel 2 zusammenwirken können.In Fig. 2 of the drawing it is shown that an additional closure 8, in particular a central closure in the form of a snap lock device 9, is also present. Windows and doors can be used, the frame 1 and sash 2 are made of wood. There, the housing 11 or the housing pot of the snap-locking device 9 is inserted into a bore 31 opening out to the peripheral circumferential surface 6 of the wing, while the latching element 13 is received by a bore 32 opening out on the peripheral peripheral surface 5 of the frame 1. In this case, the stops or collars 24 and 30 are expediently provided on one side only, projecting from the circumference of the housing 11 or housing pot and the locking element 13, and are designed in such a way that they can also interact with the frame 1 and the sash 2 as alignment means and anti-rotation devices .
