Description

Die Erfindung betrifft einen Flügelfeststeller für Fenster und Türen, insbesondere für solche mit Drehkippflügel, mit zwei durch ein Kniegelenk schwenkbeweglich miteinander verbundenen Armen, von denen der eine durch ein zum Kniegelenk paralleles Zapfengelenk am feststehenden Rahmen in einem Lagerbock aufgehängt ist, während der andere an einem flügelseitigen Lagerbock über ein ebenfalls parallel zum Kniegelenk gerichtetes Zapfengelenk angreift, das durch eine Handhabe entkuppelbar ist, wobei das Kniegelenk mit einer Reibungsbremse-und einer Einstellvorrichtung hierfür ausgestattet ist.The invention relates to a wing lock for windows and doors, in particular for those with tilt and turn sash, with two arms pivotally connected by a knee joint, one of which is suspended by a pin joint parallel to the knee joint on the fixed frame in a bearing block, while the other is attached to one wing-side bearing block engages via a pin joint which is also directed parallel to the knee joint and which can be uncoupled by means of a handle, the knee joint being equipped with a friction brake and an adjusting device therefor.

Ein Flügelfeststeller der vorstehend näher beschiebenen Art gehört bereits durch die US-PS 2 402 772 zum Stand der Technik. Die zum Kuppeln und Entkuppeln des Flügelfeststellers mit dem flügelseitigen Lagerbock dienende Handhabe ist hierbei als zweiarmiger Schwenkhebel ausgebildet, der an dem dem flügelseitigen Lagerbock zugeordneten Arm des Fensterfeststellers verstellbar gehalten ist. Der längere Hebelarm dieses zweiarmigen Schwenkhebels bildet dabei die Bedienungshandhabe, während dessen kürzerer Hebelarm als Kupplungselement wirksam ist.A wing lock of the type described in more detail above already belongs to the prior art through US Pat. No. 2,402,772. The handle serving for coupling and uncoupling the wing lock with the wing-side bearing block is designed here as a two-armed pivot lever which is adjustably held on the arm of the window lock associated with the wing-side bearing block. The longer lever arm of this two-armed swivel Lever forms the operating handle, while the shorter lever arm acts as a coupling element.

Der dem flügelseitigen Lagerbock zugeordnete Arm dieses Flügelfeststellers ist mit einem Eingriffsloch für einen über die eine Seitenfläche des flügelseitigen Lagerbocks vorstehenden, kurzen Lagerzapfen versehen. Wenn der Zapfen in das Eingriffsloch eingerückt ist, läßt sich der kürzere Hebelarm des zweiarmigen Schwenkhebels hinter die dem Zapfen abgewendete Seitenfläche des flügelseitigen Lagerbocks stellen und sichert dadurch die Kupplungsverbindung des Armes mit dem flügelseitigen Lagerbock.The arm of this wing stop associated with the wing-side bearing block is provided with an engagement hole for a short bearing journal projecting beyond the one side surface of the wing-side bearing block. When the pin is engaged in the engagement hole, the shorter lever arm of the two-armed swivel lever can be placed behind the side surface of the wing-side bearing block facing away from the pin, and thereby secures the coupling connection of the arm to the wing-side bearing block.

Dieser bekannte Flügelfeststeller hat den wesentlichen Nachteil,daß er aufgrund der eigenartigen Anordnung des Schwenkhebels nur bei geöffnetem Flügel mit dem an diesem sitzenden Lagerbock gekuppelt und auch entkuppelt werden kann. Nur wenn nämlich der mit dem flügelseitigen Lagerbock zusammenwirkende Arm des Flügelfeststellers um einen relativ großen Winkel aus seiner Parallellage zum Flügel verstellt ist, läßt sich nämlich der an ihm gehaltene Schwenkhebel so weit verlagern, daß sein kurzer Hebelarm den Kupplungsbereich zwischen dem flügelseitigen Lagerbock und dem zugeordneten Arm zu Durchführung des Kupplungs- bzw. Entkupplungsvorgangs freigeben kann.This known wing lock has the major disadvantage that, due to the peculiar arrangement of the pivoting lever, it can only be coupled and uncoupled to the bearing block seated on it when the wing is open. Only when the arm of the wing lock cooperating with the wing-side bearing bracket is adjusted by a relatively large angle from its parallel position to the wing, can the pivot lever held on it be shifted so far that its short lever arm moves the coupling area between the wing-side bearing bracket and the associated one Can release arm to perform the coupling or uncoupling process.

Nach der Erfindung ist nun ein Flügelfeststeller der eingangs näher angegebenen Ausführung geschaffen worden, welcher die Nachteile der bekannten Bauart nicht aufweist. Er zeichnet sichin erster Linie dadurch aus, daß die Handhabe aus einem Schieber besteht, der am flügelseitigen Lagerbock quer zur Achse des Zapfengelenkes verstellbar geführt ist und eine Kupplungsklaue trägt, die mit einem Gelenkbolzen an dem dem flügelseitigen Lagerbock benachbarten Arm derart korrespondiert, daß diese bei Eingriffslage als Lagerschale für den am Arm sitzenden Gelenkbolzen wirksam ist und mit diesem das Zapfengelenk am flügelseitigen Lagerbock bildet, während in ihrer Ausrücklage dieses Zapfengelenk aufgelöst ist.According to the invention, a wing lock of the design specified in the introduction has now been created, which does not have the disadvantages of the known type. It is characterized primarily by the fact that the handle consists of a slide which is guided on the wing-side bearing block transversely to the axis of the pivot joint and carries a coupling claw, which corresponds to a joint pin on the arm adjacent to the wing-side bearing block in such a way that this at The engagement position is effective as a bearing shell for the hinge pin sitting on the arm and with it the peg forms joint on the wing-side bearing block, while in its disengagement position this pin joint is dissolved.

Diese Kupplungsvorrichtung läßt sich problemlos bei am feststehenden Rahmen mit zusammengefalteten Armen anliegendem Flügelfeststeller betätigen, so daß dieser bei Schließlage des Flügels mit diesem verbunden bzw. von diesem gelöst werden kann. Hierdurch ist die Wahlmöglichkeit gegeben, den Flügel des Fensters entweder mit wirksamem Flügelfeststeller oder aber bei unwirksamem Flügelfeststeller zu öffnen.This coupling device can be actuated without problems with the wing lock resting on the fixed frame with folded arms, so that it can be connected to or detached from the wing when the wing is in the closed position. This gives the option of opening the sash of the window either with an effective sash retainer or with an ineffective sash retainer.

In vorteilhafter Weise wird der erfindungsgemäße Flügelfeststeller so ausgebildet, daß der flügelseitige Lagerbock aus einem muschel-, wannen- oder schiffchenartigen Formteil besteht, das mit der Sichtfläche des feststehenden Rahmens zugewendeter Öffnungsseite und über eine Längsseitenwand an der Uberschlagsumfangsfläche des Fenster- oder Türflügels anliegend an diesem befestigbar ist, wobei er ein Abdeckgehäuse bildet, das bei Schließlage des Flügels die beiden kniegelenkartig verbundenen Arme sowie die zugehörige Reibungsbremse mit Einstellvorrichtung umschließt.Advantageously, the sash lock according to the invention is designed so that the wing-side bearing block consists of a shell, tub or boat-like molded part, which faces the opening side facing the fixed frame and via a longitudinal side wall on the rollover circumferential surface of the window or door sash can be fastened, wherein it forms a cover housing which, when the wing is in the closed position, encloses the two arms connected in the manner of a knee joint and the associated friction brake with adjusting device.

Bewährt hat sich ferner eine erfindungsgemäße Ausgestaltung, bei der einer der beiden Arme wenigstens im Bereich des Kniegelenks zwei parallele Wangen hat, während der andere Arm in diesem Bereich drei parallele Wangen aufweist, wobei diese Wangen der beiden Arme wechselseitig nebeneinanderliegend im Kniegelenk vier zusammenwirkende Reibungsbremsbereiche bilden, welche durch die zugleich die Kniegelenkachse bildende Einstellvorrichtung beeinflußbar sind.An embodiment according to the invention has also proven itself, in which one of the two arms has two parallel cheeks at least in the area of the knee joint, while the other arm has three parallel cheeks in this area, these cheeks of the two arms mutually juxtaposed in the knee joint forming four interacting friction braking areas which can be influenced by the adjusting device which also forms the knee joint axis.

Schließlich hat es sich auch als zweckmäßig erwiesen, den die Handhabe bildenden Teil des Schiebers auf der raumseitigen Fläche der der Öffnungsseite gegenüberliegenden Wand des Formteils vorzusehen, während der die Kupplungsklaue aufweisende Teil desselben an der Innenfläche dieser Wand angeordnet ist.Finally, it has also proven expedient to provide the part of the slide forming the handle on the room-side surface of the wall of the molded part opposite the opening side, during which the Coupling claw part of the same is arranged on the inner surface of this wall.

Damit die durch die Handhabe wahlweise in und außer Eingriff bringbaren Kupplungselemente sich nicht selbsttätig in unerwünschter Weise verstellen können, ist es zweckmäßig, zwischen dem Schieber und dem ihn tragenden flügelseitigen Lagerbock eine Rastvorrichtung anzuordnen, die in beiden möglichen Endstellungen des Schiebers wirksam ist und nur durch Aufbringung einer genügend großen manuellen Stellkraft überwunden werden kann.So that the coupling elements that can be brought into and out of engagement by the handle cannot automatically adjust themselves in an undesirable manner, it is expedient to arrange a latching device between the slide and the wing-side bearing bracket that supports it, which is effective in both possible end positions of the slide and only by Application of a sufficiently large manual actuating force can be overcome.

Weitere Merkmale und Vorteile des Gegenstandes der Erfindung werden nachfolgend an einem in der Zeichnung dargestellten Ausführungsbeispiel erläutert. Es zeigt

In der Zeichnung ist der feststehende Rahmen 1 und der Flügel 2 eines Fensters, einer Tür od. dgl. zu sehen. Damit der Flügel 2 relativ zum feststehenden Rahmen 1 über einen begrenzten Öffnungsbereich hinweg in verschiedenen, stufenlos einstellbaren Spaltöffnungslagen festgehalten werden kann, wird ein Flügelfeststeller 3 benutzt, der einerseits am feststehenden Rahmen 1 und andererseits am Flügel 2 angreift.In the drawing, the fixed frame 1 and the wing 2 of a window, a door or the like can be seen. So that the sash 2 can be held relative to the fixed frame 1 over a limited opening area in various, continuously adjustable gap opening positions, a sash lock 3 is used, which acts on the one hand on the fixed frame 1 and on the other hand on the sash 2.

Der Flügelfeststeller 3 weist dabei zwei Arme 4 und 5 auf, die miteinander durch ein Kniegelenk 6 verbunden sind. Der Arm 4 ist dabei über ein Zapfengelenk 7, das parallel zum Kniegelenk 6 verläuft, in einem Lagerbock 8 gehalten, der am feststehenden Rahmen 1 befestigt wird, wie das deutlich den Fig. 1 bis 3 entnommen werden kann. Der Arm 5 wirkt über ein ebenfalls parallel zum Kniegelenk 6 gerichtetes Zapfengelenk 9 mit einem am Flügel 2 befestigten Lagerbock 10 zusammen.The wing lock 3 has two arms 4 and 5, which are connected to each other by a knee joint 6. The arm 4 is held via a pin joint 7, which runs parallel to the knee joint 6, in a bearing block 8 which is fastened to the fixed frame 1, as can be clearly seen in FIGS. 1 to 3. The arm 5 interacts via a pin joint 9 also directed parallel to the knee joint 6 with a bearing block 10 attached to the wing 2.

Während der Lagerbock 8 am feststehenden Rahmen 1 auf dessen raumseitiger Stirnfläche 1 befestigt wird, ist der Lagerbock 10 am Flügel 2 so angebracht, daß er an der Umfangsfläche 2' des Flügelüberschlags anliegt. Diese Anordnung ist besonders deutlich in Fig. 3 der Zeichnung zu sehen.While the pedestal 8 is attached to the fixed frame 1 on the room-side end face 1, the pedestal 10 is attached to the wing 2 so that it bears against the peripheral surface 2 'of the wing flap. This arrangement can be seen particularly clearly in FIG. 3 of the drawing.

Der rahmenseitige Lagerbock 8 weist eine Grundplatte 11 auf, von der im rechten Winkel zwei parallele Wangen 12' und 12" abstehen, in denen der Gelenkzapfen 13 gehalten ist. Zwischen den beiden Wangen 12' und 12" ist auf dem Gelenkzapfen 13 der Arm 4 schwenkbar gehalten, und zwar mittels einer beidseitig abgesetzten Zunge 14. Im Anschluß an die Zunge 14 weist der Arm 4 eine Dicke auf, welche etwa gleich dem Abstandsmaß zwischen den Außenflächen der beiden Wangen 12' und 12" des rahmenseitigen Lagerbocks 8 ist. Dabei hat der Arm 4 eine einseitig offene Längsnut 15, die in Richtung zum Kniegelenk 6 hin mit einer Verengung zwischen zwei Wangen 16' und 16" ausmündet, die deutlich in Fig. 3 zu sehen sind.The frame-side bearing block 8 has a base plate 11, from which two parallel cheeks 12 'and 12 "protrude at right angles, in which the pivot pin 13 is held. Between the two cheeks 12' and 12" is the arm 4 on the pivot pin 13 pivotally held, namely by means of a tongue 14 offset on both sides. Following the tongue 14, the arm 4 has a thickness which is approximately equal to the distance between the outer surfaces of the two cheeks 12 'and 12 "of the frame-side bearing block 8 the arm 4 has a longitudinal groove 15 which is open on one side and opens towards the knee joint 6 with a constriction between two cheeks 16 'and 16 ", which can be clearly seen in FIG. 3.

Der Arm 5 weist drei im Abstand voneinander und parallel zueinander liegende Wangen 17', 17" und 17"' auf, die durch einen Steg 18 miteinander in Verbindung stehen, weicher sich nur über einen kurzen Längenabschnitt des Armes 5 hinweg erstreckt. Am Kniegelenk 6 liegen die beiden Wangen 17' und 17" des Armes 5 mit ihren Innenflächen jeweils an den Außenflächen der beiden Wangen 16' und 16" des Armes 4 an, während dort die Wange 17''' des Armes 5 zwischen die Wangen 16' und 16" des Armes 4 eingreift, und zwar so, daß die Innenflächen der Wangen 16' und 16" an den Außenflächen der Wange 17''' des Armes 5 zur Anlage kommen.The arm 5 has three cheeks 17 ′, 17 ″ and 17 ″ ′ which are spaced apart from one another and parallel to one another and are connected to one another by a web 18, which extends only over a short length section of the arm 5. On the knee joint 6, the two cheeks 17 'and 17 "of the arm 5 rest with their inner surfaces on the outer surfaces of the two cheeks 16' and 16" of the arm 4, while there the cheek 17 '' 'of the arm 5 between the cheeks 16 'and 16 "of the arm 4 engages in such a way that the inner surfaces of the cheeks 16' and 16" come to rest on the outer surfaces of the cheek 17 '' 'of the arm 5.

Das Kniegelenk 6 zwischen den beiden Armen 4 und 5 wird von einer Hülsenmutter 19 und einer damit in Eingriff gebrachten Schraube 20 gebildet, die als Einstellvorrichtung zusammenwirken, über welche im Bereich des Kniegelenkes 6 die Wangen 16' und 16" des Armes 4 und die Wangen 17' , 17"und 17''' des Armes 5 gegeneinander verspannt werden können, so daß ihre aneinanderliegenden Flächen als in ihrer Bremswirkung einstellbare Reibungsbremse zusammenwirken. Diese Reibungsbremse arbeitet dabei mit vier Paaren von Reibungsflächen und macht es daher möglich, über die von der Hülsenmutter 19 und der Schraube 20 gebildete Einstellvorrichtung auf einfache Art und Weise die jeweils gewünschte Bremskraft einzustellen.The knee joint 6 between the two arms 4 and 5 is formed by a sleeve nut 19 and a screw 20 engaged therewith, which cooperate as an adjusting device via which the cheeks 16 'and 16 "of the arm 4 and the cheeks are in the region of the knee joint 6 17 ', 17 "and 17"' of the arm 5 can be braced against one another, so that their abutting surfaces interact as a friction brake adjustable in their braking action. This friction brake works with four pairs of friction surfaces and therefore makes it possible to set the desired braking force in a simple manner via the adjusting device formed by the sleeve nut 19 and the screw 20.

Die mittlere Wange 17''' des Armes 5 erstreckt sich vom Kniegelenk 6 aus nur über diejenige Teillänge des Armes 5, auf welcher sich der Steg 18 befindet. Dabei hat die Wange 17''' über die Länge des Steges 18 hinweg eine Breite, die höchstens der halben Breite der beiden Wangen 17' und 17'' des Armes 5 entspricht. Im zusammengefalteten Zustand der beiden Arme 4 und 5, wie er aus den Fig. 2 und 5 der Zeichnung ersichtlich ist, wird dabei die Wange 17''' des Armes 5 in der Nut 15 des Armes 4 aufgenommen.The middle cheek 17 '' 'of the arm 5 extends from the knee joint 6 only over that part of the length of the arm 5 on which the web 18 is located. The cheek 17 '' 'over the length of the web 18 has a width which corresponds to at most half the width of the two cheeks 17' and 17 '' of the arm 5. In the folded state of the two arms 4 and 5, as can be seen from FIGS. 2 and 5 of the drawing, the cheek 17 '' 'of the arm 5 is received in the groove 15 of the arm 4.

Der am Flügel 2, und zwar an der Umfangsfläche 2' seines Überschlags anliegend befestigte Lagerbock 10 ist als ein muschel-, wannen- oder schiffchenartiges Formteil ausgeführt, das zwei parallele Längsseitenwände 21' und 21" aufweist, die durch eine Bodenwand 22 sowie zwei von dieser ausgehende Querwände 23' und 23" einstückig miteinander verbunden sind. Über eine der beiden Längsseitenwände 21 und 21'', beispielsweise die Längsseitenwand 21; wird der Lagerbock 10 über zwei Schrauben 24', 24" so an der Umfangsfläche 2' des Flügelüberschlags befestigt, daß seine von den Endkanten der beiden Längsseitenwände 21' und 21" und der Querwände 23', 23" begrenzte Öffnungsseite 25 der Stirnfläche 1' des feststehenden Rahmens 1 zugewendet ist. Länge und Breite des den flügelseitigen Lagerbock 10 bildenden muschel- wannen- oder auch schiffchenartigen Formteils sind so bemessen, daß dieses die beiden Arme 4 und 5 des Flügelfeststellers 3 in dem aus den Fig. 2 und 5 ersichtlichen, zusammengefalteten Zustand völlig aufnehmen und umschließen kann, wenn der Flügel 2 in Schließlage am feststehenden Rahmen 1 anliegt.The bearing block 10 attached to the wing 2, namely to the peripheral surface 2 'of its rollover, is designed as a shell, tub or boat-like molded part which has two parallel longitudinal side walls 21' and 21 ", which are separated by a bottom wall 22 and two of these outgoing transverse walls 23 'and 23 "are integrally connected to one another. Via one of the two long side walls 21 and 21 ″, for example the long side wall 21; the bearing block 10 is attached to the peripheral surface 2 'of the wing flap by two screws 24', 24 "in such a way that its opening side 25 of the end face 1 'delimited by the end edges of the two longitudinal side walls 21' and 21" and the transverse walls 23 ', 23 " of the fixed frame 1. The length and width of the shell-like or boat-like molded part forming the wing-side bearing block 10 are dimensioned such that the two arms 4 and 5 of the wing lock 3 in the position shown in FIGS. can fully accommodate and enclose the folded state when the wing 2 abuts the fixed frame 1 in the closed position.

An der Bodenwand 22 des den rahmenseitigen Lagerbock 10 bildenden Formteils ist außenseitig eine Handhabe 26 angeordnet, die mit einer Oberflächenaufrauhung 27, beispielsweise Querrillen, versehen ist, und über Stege 28 in Längsschlitzen 29 der Bodenwand 22 begrenzt verschiebbar geführt wird.On the bottom wall 22 of the molded part which forms the frame-side bearing block 10, a handle 26 is arranged on the outside, which is provided with a surface roughening 27, for example transverse grooves, and is guided so as to be displaceable to a limited extent via webs 28 in longitudinal slots 29 of the bottom wall 22.

An der Innenseite der Bodenwand 22 liegt eine flache Platte 30 an, die über die Stege 28 fest mit der Handhabe 26 vernietet ist und zusammen mit dieser einen Schieber 31 bildet. Am einen Ende der flachen Platte 30 ist der Schieber 31 mit einem Mittelsteg 32 versehen, der parallel zu den Längsseitenwänden 21' und 21" des den Lagerbock 10 bildenden Formteils und mittig zwischen diesen liegt, wie das die Fig. 3 deutlich zeigt. Dieser Mittelsteg 32 ist mit einer nach oben offenen Ausnehmung 33 versehen, durch die der Mittelsteg 32 eine gabelförmige Umrißform erhält. Durch die Handhabe 26 läßt sich der Schieber 31 über einen durch die Längendifferenz der Stege 28 und der von ihnen durchgriffenen Längsschlitze 29 bestimmten Weg an dem den flügelseitigen Lagerbock 10 bildenden Formteil verschieben, wobei seine beiden Endstellungen vorteilhaft durch Zusammenwirken mit geeigneten Federrastvorrichtungen fixierbar sind. Bei am feststehenden Rahmen 1 anliegendem Flügel 2 kann durch Betätigen der Handhabe 26 der Schieber 31 so verlagert werden, daß sein gabelförmiger Mittelsteg 32 als Lagerschale mit einem Bolzen 34 in und außer Eingriff gebracht werden kann, der am freien Ende des Armes 5 zwischen dessen beiden Wangen 17'und 17" befestigt ist. Steht der als Lagerschale wirkende Mittelsteg 32 des Schiebers 31 mit dem Bolzen 34 des Armes 15 in Eingriff, dann ist der Flügelfeststeller 3 mit dem Flügel 2 gekuppelt und dieser läßt sich über einen begrenzten Öffnungsbereich hinweg in jeder möglichen Öffnungsweite fixieren, weil die im Kniegelenk 6 zwischen den beiden Armen 4 und 5 angeordnete Reibungsbremse mit einstellbarer Bremskraft wirksam ist.On the inside of the bottom wall 22 is a flat plate 30 which is firmly riveted to the handle 26 via the webs 28 and together with this forms a slide 31. At one end of the flat plate 30, the slide 31 is provided with a central web 32, which is parallel to the longitudinal side walls 21 'and 21 "of the molded part forming the bearing block 10 and centrally between them, as is clearly shown in FIG. 3. This central web 32 is provided with a recess 33 which is open at the top and through which the central web 32 is given a fork-shaped outline shape. The handle 26 allows the slide 31 to be moved by means of a difference in the length of the webs 28 and the longitudinal slots 29 penetrated by them move on the molded part forming the wing-side bearing block 10, its two end positions advantageously being fixable by cooperation with suitable spring locking devices. When the fixed frame 1 wing 2 can be moved by operating the handle 26 of the slider 31 so that its fork-shaped central web 32 can be brought into and out of engagement as a bearing shell with a bolt 34 which is at the free end of the arm 5 between the two Cheeks 17 'and 17 "is fastened. If the central web 32 of the slide 31, which acts as a bearing shell, engages with the bolt 34 of the arm 15, then the wing lock 3 is coupled to the wing 2 and this can be opened in a restricted opening area in each fix the possible opening width because the friction brake arranged in the knee joint 6 between the two arms 4 and 5 is effective with an adjustable braking force.

Wird der als Lagerschale wirksame Mittelsteg 32 des Schiebers 31 durch Bewegen der Handhabe 26 aus der oberen Stellung nach Fig. 1 in die untere Stellung gemäß Fig. 2 gebracht, dann gelangt er mit dem Bolzen 34 außer Eingriff und der Flügel 2 läßt sich gegenüber dem feststehenden Rahmen 1 bewegen, ohne daß die beiden Arme 4 und 5 des Flügelfeststellers 3 mitbewegt werden. Diese verbleiben vielmehr unter der Einwirkung der Reibungsbremse in ihrer zusammengefalteten Lage am feststehenden Rahmen 1, während sich nur der flügelseitige Lagerbock 10 mit dem Flügel 2 bewegt, wie das aus Fig. 2 hervorgeht.If the central web 32 of the slide 31, which acts as a bearing shell, is brought into the lower position according to FIG. 2 by moving the handle 26 from the upper position according to FIG. 1, then it disengages from the bolt 34 and the wing 2 can be opposite the move fixed frame 1 without the two arms 4 and 5 of the sash lock 3 are also moved. Rather, they remain under the action of the friction brake in their folded position on the fixed frame 1, while only the wing-side bearing block 10 moves with the wing 2, as can be seen from FIG. 2.
