Abstract

A hinge fitting 1 for windows, doors or the like, which is used especially with a setting-out device for turn-and-tilt wings, is described. It consists of a hinge arm 7 which engages on the wing and which is connected to the first leg 9 of an intermediate piece 8, the second leg 10 of which is connected to the tab 6 of a sleeve part 4 so as, for the purpose of selective right-hand and left-hand fastening, to be pivotable through 180 DEG about an axis 11 directed essentially parallel to the longitudinal direction of the hinge arm 7. The sleeve part 4 is held by the joint pin 3 of a bearing block 2 which is mounted on the room-side end face of the fixed frame. The second leg 10 of the intermediate piece 8 is provided, near the region of transition in the first leg 9, along the longitudinal centre with a cutout or perforation, into which can be engaged a nose 15 set off along the longitudinal centre at the rear end of the hinge arm 7. The tab 6 of the sleeve part 4 can, in either of its two possible 180 DEG end pivoting positions, be fixed relative to the second leg 10 of the intermediate piece 8 by snap-catch devices, in each of which a catch projection engages into a catch recess. There is provided as a catch projection, on or in the vicinity of each transverse edge of the sleeve-part tab 6, a catch tooth projecting out of the plane of the latter towards the second leg 10 of the intermediate piece 8, whilst the cutout or perforation of the second leg of the intermediate piece is used as a catch recess. One catch tooth can be engaged in each case in the cutout or perforation and has a blocking flank which engages behind a longitudinal edge of the cutout or perforation and which blocks the reverse rotation of the sleeve-part tab 6 relative to the intermediate piece 8. <IMAGE>

Scharnierbeschlag für Fenster, Türen od. dgl., insbesondere an der Ausstellvorrichtung für Drehkippflügel, bestehend aus einem Scharnierarm, der am Flügel angreift und mit dem ersten Schenkel eines Zwischenstücks verbunden ist, dessen rechtwinklig zum ersten Schenkel verlaufender zweiter Schenkel mit dem Lappen eines Hülsenteils für den wahlweisen Rechts- und Linksanschlag um 180° um eine im wesentlichen parallel zur Längsrichtung des ersten Schenkels gerichtete Achse verschwenkbar in Verbindung steht, wobei das Hülsenteil vom Gelenkbolzen eines Lagerbocks schwenkbar gehalten wird, welcher an der raumseitigen Stirnfläche des feststehenden Rahmens angebracht ist, wobei der zweite Schenkel des Zwischenstücks nahe dem Übergangsbereich in den ersten Schenkel längsmittig mit einem Ausschnitt oder Durchbruch versehen ist, wobei der Scharnierarm an seinem hinteren Ende mit einer längsmittig angeordneten, abgesetzten Nase versehen und mit dieser in den Ausschnitt oder Durchbruch im zweiten Schenkel des Zwischenstücks einrückbar ist,
und wobei der Lappen des Hülsenteils in jeder seiner beiden möglichen 180°-Endschwenklagen relativ zum zweiten Schenkel des Zwischenstücks durch Schnapp-Rastvorrichtungen fixierbar ist, bei denen jeweils ein Rastvorsprung in eine Rastvertiefung eingreift.Hinge fitting for windows, doors or the like, in particular on the opening device for tilt-and-turn sashes, consisting of a hinge arm that engages the wing and is connected to the first leg of an intermediate piece, the second leg of which runs at right angles to the first leg with the tab of a sleeve part for the optional right and left stop can be pivoted through 180 ° about an axis directed essentially parallel to the longitudinal direction of the first leg, the sleeve part being pivoted by the hinge pin of a bearing block which is attached to the face-side end face of the fixed frame, the second leg of the intermediate piece near the transition region in the first leg is provided with a cutout or opening in the longitudinal center, the hinge arm being provided at its rear end with a longitudinally arranged, offset nose and with this in the cutout or through hole h can be engaged in the second leg of the intermediate piece,
and wherein the tab of the sleeve part can be fixed in each of its two possible 180 ° end swivel positions relative to the second leg of the intermediate piece by snap-locking devices, in each of which a locking projection engages in a locking recess.

Durch die DE-PS 37 02 957 ist ein derartiger Scharnierbeschlag bekannt. Dieser zeichnet sich im wesentlichen dadurch aus, daß er in ein und derselben Grundkonzeption sowohl bei Fenstern und Türen mit Dreh-, Kipp-und Klappflügeln als auch bei solchen mit Drehkippflügeln zum Einsatz gebracht werden kann, weil sich Scharnierarm und Zwischenstück durch einfache Steck-Kupplungsverbindungen schnell und funktionssicher sowohl zusammenbauen als auch demontieren lassen. Folglich kann das Zwischenstück bedarfsweise entweder mit einem Scharnierarm in Wirkverbindung gebracht werden, der den Ausstellarm an einer Ausstellvorrichtung für Drehkippflügel bildet oder aber es wird mit einem Scharnierarm verbunden, welcher für die starre Befestigung an einem Drehflügel, Kippflügel oder Klappflügel eingerichtet ist.Such a hinge fitting is known from DE-PS 37 02 957. This is characterized essentially by the fact that it is used in the same basic concept both for windows and doors with pivoting, tilting and folding sashes and for those with pivoting and tilting sashes can be brought, because the hinge arm and intermediate piece can be assembled and disassembled quickly and reliably using simple plug-in connections. Consequently, the intermediate piece can either be brought into operative connection with a hinge arm, which forms the extension arm on an opening device for tilt-and-turn sash, or it is connected to a hinge arm, which is set up for rigid attachment to a rotary sash, tilting sash or folding sash.

Ein weiterer Vorteil des bekannten Scharnierbeschlages liegt darin, daß er mit relativ geringem Einbauraum in den Eckzonen von Flügel und Rahmen weitestgehend verdeckt zwischen den Falzflächen untergebracht werden kann.Another advantage of the known hinge fitting is that it can be accommodated as far as possible between the rebate surfaces with relatively little installation space in the corner zones of the sash and frame.

Ein und derselbe Scharnierbeschlag ist dabei für den wahlweisen Rechts-und Linksanschlag ausgelegt. Zu diesem Zweck steht der Lappen des Hülsenteils mit dem zweiten Schenkel des Zwischenstücks über eine im wesentlichen parallel zur Längsrichtung des ersten Schenkels des Zwischenstücks gerichtete Achse in verschwenkbarer Gelenkverbindung. Darüberhinaus ist der Scharnierbeschlag mit Schnapp-Rastvorrichtungen ausgestattet, über welche zwei 180°-Endschwenklagen des Hülsenteil-Lappens relativ zum Zwischenstück selbsttätig fixierbar sind.One and the same hinge fitting is designed for the optional right and left hinging. For this purpose, the tab of the sleeve part is pivotally articulated to the second leg of the intermediate piece via an axis directed essentially parallel to the longitudinal direction of the first leg of the intermediate piece. In addition, the hinge fitting is equipped with snap locking devices, by means of which two 180 ° end pivoting positions of the sleeve part flap can be automatically fixed relative to the intermediate piece.

Beim Scharnierbeschlag nach DE-PS 37 02 957 werden die Schnapp-Rastvorrichtungen dadurch gebildet, daß Einschnitte bzw. Ausklinkungen an den Querkanten des Hülsenteil-Lappens mit der am hinteren Ende des Scharnierarms angeordneten Nase in Wirkverbindung treten, und zwar dergestalt, daß über die Querkanten des Hülsenteil-Lappens eine elastische Verspannung des Scharnierarms gegen den ersten Schenkel des Zwischenstücks bewirkt wird und anschließend die Nase am hinteren Ende des Scharnierarms elastisch in den benachbarten Einschnitt bzw. die benachbarte Ausklinkung der Querkante des Lappens zurückspringt.In the hinge fitting according to DE-PS 37 02 957, the snap-locking devices are formed in that incisions or notches on the transverse edges of the sleeve part flap come into active connection with the nose arranged at the rear end of the hinge arm, in such a way that over the transverse edges of the sleeve part flap an elastic bracing of the hinge arm against the first leg of the intermediate piece is effected and then the nose at the rear end of the hinge arm resiliently springs back into the adjacent cut or the notching of the transverse edge of the flap.

Die praktische Erfahrung hat jedoch gezeigt, daß durch das Zusammenwirken von drei verschiedenen Funktionsteilen zur Bildung der Schnapp-Rastvorrichtungen eine optimale Wirkungsweise nicht immer gewährleistet werden kann. Schon relativ geringe Fertigungstoleranzen an den drei zusammenwirkenden Funktionsteilen können nämlich dazu führen, daß die Schnapp-Rastvorrichtungen entweder zu schwergängig oder aber zu leichtgängig funktionieren.Practical experience has shown, however, that by the interaction of three different functional parts to form the snap-locking devices optimal functioning cannot always be guaranteed. Even relatively small manufacturing tolerances on the three interacting functional parts can cause the snap-locking devices to function either too stiff or too smoothly.

Der Erfindung liegt deshalb die Aufgabe zugrunde, einen Scharnierbeschlag der eingangs näher spezifizierten Gattung unter Beibehaltung seiner Vorteile so fortzubilden, daß die die Einstellung auf Rechts- oder Linksanschlag sicherenden Schnapp-Rastvorrichtungen bei baulich vereinfachter Auslegung noch zuverlässiger als bisher wirken.The invention is therefore based on the object to further develop a hinge fitting of the type specified in the introduction, while maintaining its advantages, so that the snap locking devices securing the setting to the right or left stop appear even more reliable than before with a structurally simplified design.

Diese Aufgabe läßt sich erfindungsgemäß - nach den Kennzeichnungsmerkmalen des Anspruchs 1 - dadurch lösen,
daß als Rastvorsprung an oder in der Nähe jeder Querkante des Hülsenteils-Lappens ein aus dessen Ebene gegen den zweiten Schenkel des Zwischenstücks hervorspringender Rastzahn vorgesehen ist,
daß als Rastvertiefung der Ausschnitt oder Durchbruch im zweiten Schenkel des Zwischenstücks genutzt ist,
daß je ein Rastzahn in den Durchbruch oder Ausschnitt einrückbar ist, und daß dabei jeder Rastzahn eine einen Längsrand des Durchbruchs oder Ausschnitts hintergreifende und die Rückdrehung des Hülsenteil-Lappens gegenüber dem Zwischenstück blockierende Sperrflanke aufweist.This object can be achieved according to the invention - according to the characterizing features of claim 1 -
that a locking tooth protruding from its plane against the second leg of the intermediate piece is provided as a locking projection on or near each transverse edge of the sleeve part flap,
that the cutout or opening in the second leg of the intermediate piece is used as a recess,
that one locking tooth can be inserted into the opening or cutout, and that each locking tooth has a locking edge engaging behind a longitudinal edge of the opening or cutout and blocking the reverse rotation of the sleeve part flap relative to the intermediate piece.

Vorteilhaft bei dieser Ausgestaltung ist, daß zur Bildung der Schnapp-Rastvorrichtungen die Nase am hinteren Ende des Scharnierarms nicht mehr benötigt wird, der eigentliche Schnapp-Rasteffekt also unmittelbar zwischen dem Hülsenteil-Lappen und dem Zwischenstück auftritt.It is advantageous in this embodiment that the nose at the rear end of the hinge arm is no longer required to form the snap-locking devices, so the actual snap-locking effect occurs directly between the sleeve part tab and the intermediate piece.

Nach einem vorteilhaften Weiterbildungsmerkmal der Erfindung ist jeder Rastzahn materialeinheitlich aus dem Hülsenteil-Lappen herausgeformt.According to an advantageous development feature of the invention, each locking tooth is molded out of the sleeve part flap using the same material.

Bewährt hat es sich erfindungsgemäß aber auch, der Sperrflanke des oder jedes Rastzahns eine flach geneigte bzw. keilförmig ansteigende Auflaufflanke vorzulagern, weil hierdurch das Einrücken der Schnapp-Rastvorrichtungen wesentlich erleichtert wird.According to the invention, however, it has also proven useful for the locking flank of the or each locking tooth to have a flat incline or a wedge-shaped rise Upstream flank, because this makes it much easier to engage the snap-in locking devices.

Wenn die Länge der Auflaufflanke des Rastzahnes annähernd der Breite des Ausschnittes bzw. Durchbruchs im zweiten Schenkel des Zwischenstücks entspricht, kann das Einrücken der Schnapp- und Rastvorrichtung mit relativ geringem Kraftaufwand herbeigeführt werden, bevor die Sperrflanke die Rückdrehung aus der End-Schwenklage blockiert.If the length of the run-up flank of the locking tooth approximately corresponds to the width of the cutout or opening in the second leg of the intermediate piece, the engagement of the snap-in and locking device can be brought about with relatively little effort before the locking flank blocks the reverse rotation from the end pivot position.

Erfindungsgemäß ist auch vorgesehen, daß von den Querkanten des Hülsenteil-Lappens ein Materialvorsprung absteht, der für die am Scharnierarm längsmittig vorspringend angeordnete Nase in endmontierter Stellung einen Stützanschlag bildet. Da die Flanke dieses Stützanschlags der Sperrflanke des Rastvorsprungs entgegengerichtet ist, wird unter Zwischenschaltung der am hinteren Ende des Scharnierarms vorspringenden Nase eine nahezu spielfreie Festlegung des Zwischenstücks gegen den Hülsenteil-Lappen herbeigeführt, sobald die jeweilige Schnapp-Rastvorrichtung in ihre Eingriffsstellung gelangt ist.According to the invention, it is also provided that a material projection protrudes from the transverse edges of the sleeve part flap, which forms a support stop for the nose which projects longitudinally centrally on the hinge arm in the fully assembled position. Since the flank of this support stop faces the locking flank of the latching projection, with the interposition of the nose projecting at the rear end of the hinge arm, an almost play-free fixing of the intermediate piece against the sleeve part tab is brought about as soon as the respective snap-in latching device has reached its engagement position.

The short leg 5a of an angle plate 5 protrudes approximately tangentially from the sleeve part 4, the long leg 5b of which extends approximately parallel to the main plane of the sash and the fixed frame when the window is in the closed position.

Einstückig mit dem Schenkel 5b der Winkelplatte 5 steht wiederum ein Lappen 6 in Verbindung, wobei dieser rechtwinklig bzw. quer zur Ebene des langen Schenkels 5b gerichtet ist.In one piece with the leg 5b of the angle plate 5 there is in turn a tab 6, which is directed at right angles or transversely to the plane of the long leg 5b.

Zum Scharnierbeschlag 1 gehören noch ein Scharnierarm 7 und ein Zwischenstück 8, wobei letzteres als Verbindungsglied zwischen dem Scharnierarm 7 und dem von der Winkelplatte 5 abstehenden Lappen 6 des Hülsenteils 4 genutzt wird.The hinge fitting 1 also includes a hinge arm 7 and an intermediate piece 8, the latter being used as a connecting link between the hinge arm 7 and the tab 6 of the sleeve part 4 protruding from the angle plate 5.

Das Zwischenstück 8 hat einen ersten, dem Scharnierarm 7 zugeordneten Schenkel 9 und weist ferner einen zweiten Schenkel 10 auf, welcher dem Lappen 6 des Hülsenteils 4 zugeordnet ist.The intermediate piece 8 has a first leg 9 assigned to the hinge arm 7 and also has a second leg 10 which is assigned to the tab 6 of the sleeve part 4.

Beide Schenkel 9 und 10 des Zwischenstücks 8 stehen miteinander in einstückiger Verbindung, wobei der zweite Schenkel 10 im wesentlichen flach an der Rückseite des Lappens 6 anliegt. Er ist über eine Achse 11, die beispielsweise von einem Niet gebildet werden kann, mit dem Lappen 6 des Hülsenteils 4 so in Gelenkverbindung gehalten, daß dieses sich parallel zu seiner Ebene und auch parallel zur Ebene des Lappens 6 über einen Winkelbereich von 180° verschwenken läßt. In jeder seiner beiden möglichen Endlagen legt sich der Schenkel 10 des Zwischenstücks 8 zumindest nahezu mit einer seiner Längskanten gegen den langen Schenkel 5b der Winkelplatte 5 an, wie das den Fig. 2 und 3 zu entnehmen ist.Both legs 9 and 10 of the intermediate piece 8 are connected to one another in one piece, the second leg 10 lying essentially flat against the back of the flap 6. It is held in an articulated connection with the tab 6 of the sleeve part 4 via an axis 11, which can be formed, for example, by a rivet, in such a way that it pivots parallel to its plane and also parallel to the plane of the tab 6 over an angular range of 180 ° leaves. In each of its two possible end positions, the leg 10 of the intermediate piece 8 at least almost lies down with one of its longitudinal edges against the long leg 5b of the angle plate 5, as can be seen in FIGS. 2 and 3.

Das Zwischenstück 8 weist in seinem ersten Schenkel 9 nahe dem Übergangsbereich in den zweiten Schenkel 10 einen Ausschnitt oder Durchbruch 12 auf. Darüber hinaus ist das freie Ende des ersten Schenkels 9 noch mit einer längsmittig angeordneten, seitlich abgesetzten Zunge 13 versehen.The intermediate piece 8 has a cutout or opening 12 in its first leg 9 near the transition region into the second leg 10. In addition, the free end of the first leg 9 is also provided with a tongue 13, which is arranged in the middle and laterally offset.

Auch der zweite Schenkel 10 des Zwischenstücks 8 ist mit einem Ausschnitt oder Durchbruch 14 versehen, welcher eine geringere Breite als der Ausschnitt oder Durchbruch 12 hat, und welcher dabei in Längsrichtung durch den Stegabschnitt geführt ist, sowie in das diesem zugewendete Ende des Ausschnitts oder Durchbruchs 12 aus läuft.The second leg 10 of the intermediate piece 8 is also provided with a cutout or opening 14 which has a smaller width than the cutout or opening 12 and which is guided in the longitudinal direction through the web section and into the end of the cutout or opening facing it 12 runs out.

Die Zunge 13 schließt sich an den ersten Schenkel 9 des Zwischenstücks 8 über eine nach abwärts gehende Verkröpfung in der Weise an, daß sie nur an ihrem freien Ende etwa auf gleicher Höhe mit der Unterseite des ersten Schenkels 9 zu liegen kommt (Fig. 1).The tongue 13 adjoins the first leg 9 of the intermediate piece 8 via a downward bend in such a way that it comes to lie only at its free end approximately at the same level as the underside of the first leg 9 (FIG. 1) .

Der Scharnierarm 7 ist an seinem hinteren Ende mit einer längsmittig angeordneten, seitlich abgesetzten Nase 15 versehen, welche eine solche Breite hat, daß sie sich in den Ausschnitt oder Durchbruch 14 am zweiten Schenkel 10 des Zwischenstücks 8 einrücken läßt, wie das in den Fig. 1, 2 und 4 zu sehen ist. Außerdem hat der Scharnierarm 7 eine im wesentlichen quer zu seiner Ebene gerichtete Verkröpfung 16, die so ausgeführt ist, daß die Oberseite seines die Nase 15 tragenden Endabschnitts 18 mindestens auf gleicher Ebene mit der Unterseite seines übrigen Längenabschnitts zu liegen kommt, vorzugsweise jedoch noch etwas tiefer als diese angeordnet ist.The hinge arm 7 is provided at its rear end with a longitudinally arranged, laterally offset nose 15, which has such a width that it can be inserted into the cutout or opening 14 on the second leg 10 of the intermediate piece 8, as shown in FIGS. 1, 2 and 4 can be seen. In addition, the hinge arm 7 has a crank 16 directed essentially transversely to its plane, which is designed such that the top of its end section 18 carrying the nose 15 comes to lie at least on the same level as the underside of its remaining length section, but preferably a little lower than this is arranged.

Im Bereich seiner Verkröpfung 16 ist der Scharnierarm 7 mit einem längsmittig liegenden Ausschnitt oder Durchbruch 17 ausgestattet, und zwar so, daß sich dieser sowohl in den Scharnierarm 7 als auch in dessen die Nase 15 tragenden Endabschnitt 18 erstreckt, wobei seine Breite auf die Breite der Zunge 13 des Zwischenstücks 8 abgestimmt ist. Die Zunge 13 des Zwischenstücks 8 läßt sich mit dem Ausschnitt oder Durchbruch 17 des Scharnierarms 7 in längsschiebbaren Führungs- und Halteeingriff bringen.In the area of its offset 16, the hinge arm 7 is provided with a cutout or opening 17 lying in the middle, in such a way that it is located both in the hinge arm 7 and in its End portion 18 carrying nose 15 extends, its width being matched to the width of the tongue 13 of the intermediate piece 8. The tongue 13 of the intermediate piece 8 can be brought into longitudinally sliding guiding and holding engagement with the cutout or opening 17 of the hinge arm 7.

Im Bereich zwischen seinem Ausschnitt oder Durchbruch 17 und der Nase 15, also auf dem Endabschnitt 18, trägt der Scharnierarm 7 einen aus seiner Ebene in Richtung der Verkröpfung 16 hochragenden Ansatz 19, welche eine Breite hat, die auf die Breite des Ausschnitts oder Durchbruchs 12 im ersten Schenkel 9 des Zwischenstücks 8 abgestimmt ist. Im Ansatz 19 ist ein zur Längsrichtung des Scharnierarms 7 paralleles Gewindeloch 20 vorhanden, in welchem wiederum ein Schraubglied 21 drehbar und axial verlagerbar gehalten ist. Dieses weist an seinem hinteren Ende einen verdickten Kopfteil 22 auf, in dessen freier Endfläche sich ein Werkzeugeingriff 23, beispielsweise in Form einer Mehrkantvertiefung, befindet. Die Längenabmessung des Schraubgliedes 21 ist dabei auf die Länge des Ausschnitts oder Durchbruchs 12 im ersten Schenkel 9 des Zwischenstücks 8 so abgestimmt, daß es mit nur geringem Längsspiel in diese eingerückt werden kann, wie das in Fig. 3 der Zeichnung durch strichpunktierte Linien angedeutet ist. In die strichpunktiert angedeutete Eingriffsstellung gelangt das Schraubglied 21, nachdem die Zunge 13 des Zwischenstücks 8 in den Ausschnitt oder Durchbruch 17 am Scharnierarm 7 eingeführt worden ist und der Ansatz 19 von der Innenseite des Schenkels 9 her in den Ausschnitt oder Durchbruch 12 eintritt. Das vordere Ende des Schraubgliedes 21 tritt dabei in Wirkverbindung mit einer Querkante 24 des Ausschnitts oder Durchbruchs 12, während die Endfläche des verdickten Kopfteils 22 in den Bereich von gegenüberliegenden Querkanten 25 gelangt. Dabei bleibt der Werkzeugeingriff 23 des verdickten Kopfteils 22 durch denjenigen Bereich des Ausschnitts oder Durchbruchs 14 zugänglich, welcher vom Schenkel 10 aus bis zu den Querkanten 25 des Ausschnitts oder Durchbruchs 12 hin geführt ist. Die Nase 15 am Endabschnitt 18 des Scharnierarms 7 greift auf einer Ebene in den Ausschnitt oder Durchbruch 14 ein, welche unterhalb des Schraubglieds 21 bzw. seines Kopfteils 22 liegt, wie das deutlich der Fig. 2 zu entnehmen ist.In the area between its cutout or opening 17 and the nose 15, that is to say on the end section 18, the hinge arm 7 carries a shoulder 19 which rises from its plane in the direction of the offset 16 and which has a width which corresponds to the width of the cutout or opening 12 is matched in the first leg 9 of the intermediate piece 8. In the extension 19 there is a threaded hole 20 parallel to the longitudinal direction of the hinge arm 7, in which in turn a screw member 21 is rotatably and axially displaceably held. At its rear end, this has a thickened head part 22, in the free end surface of which there is a tool engagement 23, for example in the form of a polygonal recess. The length dimension of the screw member 21 is matched to the length of the cutout or opening 12 in the first leg 9 of the intermediate piece 8 so that it can be inserted into it with only a little longitudinal play, as is indicated in Fig. 3 of the drawing by dash-dotted lines . In the engagement position indicated by dash-dotted lines, the screw member 21 comes after the tongue 13 of the intermediate piece 8 has been inserted into the cutout or opening 17 on the hinge arm 7 and the shoulder 19 enters the cutout or opening 12 from the inside of the leg 9. The front end of the screw member 21 comes into operative connection with a transverse edge 24 of the cutout or opening 12, while the end face of the thickened head part 22 reaches the region of opposite transverse edges 25. The tool engagement 23 of the thickened head part 22 remains accessible through that region of the cutout or opening 14 which is guided from the leg 10 to the transverse edges 25 of the cutout or opening 12. The nose 15 on the end section 18 of the hinge arm 7 engages in the cutout or opening 14 on a plane which lies below the screw member 21 or its head part 22, as can be clearly seen in FIG. 2.

Durch Verdrehung des Schraubgliedes 21 im Gewindeloch 20 des Ansatzes 19 führt es relativ zu diesem eine Axialverlagerung aus. Da es dabei zwischen den Querkanten 24 und 25 gefangen ist, findet eine durch die Gewindesteigung bestimmte Längsverlagerung des Ansatzes 19 innerhalb des Ausschnitts oder Durchbruchs 12 und damit eine entsprechende Längsverlagerung des Scharnierarms 7 am Zwischenstück 8 statt. Diese Längsverlagerung ist dabei der Regulierung der Einbaulage des Flügels gegenüber dem feststehenden Rahmen dienlich, und zwar unter Zuhilfenahme eines in den Werkzeugeingriff 23 einführbaren Steckschlüssels.By rotating the screw member 21 in the threaded hole 20 of the projection 19, it performs an axial displacement relative to this. Since it is caught between the transverse edges 24 and 25, a longitudinal displacement of the projection 19, determined by the thread pitch, takes place within the cutout or opening 12 and thus a corresponding longitudinal displacement of the hinge arm 7 on the intermediate piece 8. This longitudinal displacement is used to regulate the installation position of the wing relative to the fixed frame, with the aid of a socket wrench that can be inserted into the tool engagement 23.

Wichtig ist, daß die Zunge 13 des Zwischenstücks 8 den Scharnierarm 7 durch den Ausschnitt oder Durchbruch 17 der Verkröpfung 16 so untergreift, daß sie an diesem nur mit ihrem vorderen Ende anliegt, während sie über ihren übrigen Längenbereich überall einen Abstand von der Unterseite des Scharnierarms 7 einhält. Andererseits kommt der Schenkel 9 des Zwischenstücks 8 nur an der Stelle der Querkanten 26 auf der Oberseite am Endabschnitt 18 des Scharnierarms 7 zur Anlage, über die die abgesetzte Zunge 13 am vorderen Ende des Schenkels 9 hinausragt.It is important that the tongue 13 of the intermediate piece 8 engages under the hinge arm 7 through the cutout or opening 17 of the crank 16 in such a way that it only rests against this with its front end, while it remains a distance from the underside of the hinge arm everywhere over its remaining length range 7 complies. On the other hand, the leg 9 of the intermediate piece 8 only comes into contact at the location of the transverse edges 26 on the upper side at the end section 18 of the hinge arm 7, beyond which the stepped tongue 13 protrudes at the front end of the leg 9.

Der rechtwinklig vom langen Schenkel 5b der Winkelplatte 5 des Hülsenteils 4 abstehende Lappen 6 ist an oder in der Nähe jeder seiner beiden Querkanten 27 mit einem Rastvorsprung ausgestattet, welcher als ein aus der Lappenebene vorspringender und gegen den zweiten Schenkel 10 des Zwischenstücks 8 gerichteter Rastzahn 28 gestaltet ist. Dabei kann sich dieser Rastvorsprung bzw. Rastzahn 28 unmittelbar an die Querkante 27 des Lappens 6 anschließen, wie das in den Fig. 4 und 5 durch voll ausgezogene Linien dargestellt ist. Er kann aber auch einen größeren Abstand von diesen Querkanten 27 einnehmen, wie das die strichpunktierten Linien in Fig. 4 andeuten. In jedem Falle ist es jedoch wichtig, daß der Rastvorsprung bzw. Rastzahn 28 mit einer steilen Sperrflanke 29 ausgestattet ist, die sich an eine gegenüber der Ebene des Lappens 6 flach geneigte bzw. keilförmig ansteigende Auflaufflanke 30 anschließt.The lug 6 protruding at right angles from the long leg 5b of the angle plate 5 of the sleeve part 4 is provided on or near each of its two transverse edges 27 with a latching projection which projects as a latching tooth 28 projecting from the lobe plane and directed against the second leg 10 of the intermediate piece 8 is designed. This locking projection or locking tooth 28 can directly adjoin the transverse edge 27 of the tab 6, as is shown in FIGS. 4 and 5 by solid lines. However, it can also be at a greater distance from these transverse edges 27, as indicated by the dash-dotted lines in FIG. 4. In any case, however, it is important that the locking projection or locking tooth 28 is equipped with a steep locking flank 29 which adjoins a rising flank 30 which is inclined flat or wedge-shaped in relation to the plane of the flap 6.

Bewährt hat es sich, wenn jeder Rastvorsprung bzw. Rastzahn 28 materialeinheitlich aus dem Lappen 6 des Hülsenteils 4 herausgeformt ist, weil er dadurch eine relativ hohe Federsteifheit erhält.It has proven to be useful if each locking projection or locking tooth 28 is formed from the flap 6 of the sleeve part 4 using the same material, because this gives it a relatively high spring stiffness.

Im rechten Winkel zu jeder Querkante 27 ist am Lappen 6 ein Absatz 31 ausgebildet an den sich wiederum im rechten Winkel ein gerader Kantenabschnitt 32 anschließt, der in einen Krümmungsbogen 33 übergeht, dessen Zentrum wenigstens annähernd mit der Achse 11 zusammenfällt.At right angles to each transverse edge 27, a shoulder 31 is formed on the tab 6, which in turn is joined at right angles by a straight edge section 32 which merges into an arc 33 whose center coincides at least approximately with the axis 11.

Durch Verschwenken des Hülsenteils 4 um die Achse 11 relativ zum Zwischenstück 8 entweder in Pfeilrichtung 34a - von rechts nach links - oder aber in Pfeilrichtung 34b - von links nach rechts - gelangt zunächst immer erst der Krümmungsbogen 33 und daran anschließend der gerade Kantenabschnitt 32 unter die vom Scharnierarm 7 bzw. seinem Endabschnitt 18 nach rückwärts abstehende Nase 15. Er setzt diese damit in Richtung gegen den ersten Schenkel 9 des Zwischenstücks 8 hin unter eine Vorspannung. Damit wird dann der Scharnierarm 7 einerseits mit seinem Endabschnitt 18 von unten gegen die Querkanten 26 des Schenkels 9 gedrückt, während er andererseits vor seiner Verkröpfung 16 auf der vorderen oberen Endkante der Zunge 13 aufliegt. Es stellt sich hierdurch eine spielfreie Federverspannung zwischen dem Scharnierarm 7 und dem Zwischenstück 8 ein. Nachdem jeweils der gerade Kantenabschnitt 32 des Lappens 6 unter die Nase 15 des Scharnierarms 7 gelangt ist, schlägt der Absatz 31 der Querkante 27 seitlich gegen diese Nase 15 an und begrenzt dadurch den Schwenkweg des Hülsenteils 4 relativ zum Zwischenstück 8.By pivoting the sleeve part 4 about the axis 11 relative to the intermediate piece 8 either in the direction of arrow 34a - from right to left - or in the direction of arrow 34b - from left to right - firstly always the curve 33 and then the straight edge section 32 below nose 15 protruding rearward from hinge arm 7 or its end section 18, thus placing it under a pretension in the direction toward first leg 9 of intermediate piece 8. Thus, the hinge arm 7 is pressed on the one hand with its end section 18 from below against the transverse edges 26 of the leg 9, while on the other hand it rests on the front upper end edge of the tongue 13 before its cranking 16. This results in a play-free spring tension between the hinge arm 7 and the intermediate piece 8. After the straight edge section 32 of the tab 6 has come under the nose 15 of the hinge arm 7, the shoulder 31 of the transverse edge 27 abuts laterally against this nose 15 and thereby limits the pivoting path of the sleeve part 4 relative to the intermediate piece 8.

Bei der Schwenkbewegung des Hülsenteils 4 um die Achse 11 relativ zum Zwischenstück 8 läuft jeweils einer der Rastzähne 28 mit seiner Auflaufflanke 30 auf die Innenfläche am Schenkel 10 des Zwischenstücks 8 auf und verformt dadurch den Lappen 6 federelastisch in Richtung vom Schenkel 10 des Zwischenstücks 8 weg. Sobald dann der betreffende Rastzahn 28 in den Bereich des Ausschnitts bzw. Durchbruchs 14 gelangt und der benachbarte Absatz 31 gegen die Seitenfläche der Nase 15 trifft, schnappt seine Sperrflanke 29 hinter den Längsrand 14a oder 14b des Ausschnitts bzw. Durchbruchs 14 ein und blockiert dadurch selbsttätig die Rückdrehung des Hülsenteils 4 gegenüber dem Zwischenstück 8 entgegen der Pfeilrichtung 34a bzw. 34b.During the pivoting movement of the sleeve part 4 about the axis 11 relative to the intermediate piece 8, one of the locking teeth 28 runs with its run-up flank 30 onto the inner surface on the leg 10 of the intermediate piece 8 and thereby resiliently deforms the tab 6 in the direction away from the leg 10 of the intermediate piece 8 . As soon as the relevant locking tooth 28 reaches the area of the cutout or opening 14 and the adjacent shoulder 31 meets the side surface of the nose 15, snaps its locking flank 29 behind the longitudinal edge 14a or 14b of the cutout or opening 14 and thereby automatically blocks the return rotation of the sleeve part 4 relative to the intermediate piece 8 against the direction of the arrow 34a or 34b.

Es hat sich bewährt, wenn die Länge der Auflaufflanke 30 jedes Rastvorsprungs oder Rastzahnes 28 annähernd der Breite des Ausschnitts bzw. Durchbruchs 14 im zweiten Schenkel 10 des Zwischenstücks 8 entspricht, wie das die Fig. 3 zeigt, so daß der jeweils wirksame Rastvorsprung bzw. Rastzahn 28 vollständig innerhalb des Ausschnitts bzw. Durchbruchs 14 aufgenommen werden kann.It has proven useful if the length of the ramp flank 30 of each locking projection or locking tooth 28 approximately corresponds to the width of the cutout or opening 14 in the second leg 10 of the intermediate piece 8, as shown in FIG. 3, so that the respectively effective locking projection or Locking tooth 28 can be received completely within the cutout or opening 14.

Es sei hier noch bemerkt, daß auch die Möglichkeit besteht, die Rastzähne 28 jeweils aus den Längskanten 14a und 14b des Ausschnitts oder Durchbruchs 14 am Schenkel 10 des Zwischenstücks 8 in Richtung gegen den Lappen 6 herauszuformen und diese dann mit dazu passenden Ausschnitten in Wirkverbindung treten zu lassen, die in diesem Falle im Lappen 6 des Hülsenteils 4 vorhanden sind.It should also be noted here that there is also the possibility of forming the latching teeth 28 in each case from the longitudinal edges 14a and 14b of the cutout or opening 14 on the leg 10 of the intermediate piece 8 in the direction against the tab 6 and then connecting them with matching cutouts to let, which are in this case in the tab 6 of the sleeve part 4.

Es handelt sich hier also gewissermaßen um eine gegenüber dem vorher beschriebenen Ausführungsbeispiel vertauschte Anordnung von Rastzähnen und Rasteingriffen, ohne daß hierdurch eine Änderung der Wirkungsweise bezüglich der Schnapp-Rastvorrichtungen eintritt.In a way, this is an arrangement of latching teeth and latching engagements that is reversed compared to the previously described exemplary embodiment, without this resulting in a change in the mode of operation with respect to the snap-in latching devices.
