Abstract

The central locking system fittings, especially the corner profiles, hinges and lock parts, are mounted in a groove (47) with an undercut (48) extending around the profiled metal or plastics sash frame periphery. Driving rod sections are used to engage lock fittings on the same end side of the sash. An arm section (32) of the guide casing for the corner profile and guide member (39) in an adjacent actuator arm (41) on the same end side of the sash both have side plates (32a,40) capable of engaging with the groove undercut. Screw fasteners (35) are used to fix the side plates into the grooves. An Independent claim is also included for the mounting of the central locking system in the sash frame.

Description

Die Erfindung betrifft einen verdeckt im Falz einbaubaren Zentralverschluss für Flügel von Fenstern oder Türen mit einem Profilrahmen aus Metall oder Kunststoff. Auch beansprucht ist ein Verfahren zum Montieren eines Zentralverschlusses.The invention relates to a hidden installed in the fold central closure for wings of windows or doors with a profile frame made of metal or plastic. Also claimed is a method of mounting a central closure.

Vielfach haben die Profilrahmen im Bereich des Flügelfalzes eine um den Flügelrahmen umlaufende Nut zur Aufnahme der Teile eines Zentralverschlusses. Bei Profilrahmen aus Metall oder Kunststoff weisen die Nuten seitliche Hinterschneidungen auf, in die seitliche Stege von Führungs- oder Halteteilen (Tragteile) des Zentralverschlusses eingreifen können, wobei zur Montage die Tragteile von den Enden der Nuten her in diese eingeschoben werden, um anschließend an der vorgesehenen Montagestelle festgelegt zu werden, vgl. DE-A 29 02 459 (Ferco ), entspricht FR-A 2 415 187 mit der dortigen Figur 1, welche die obere Ecke von einer Montagestelle für eine Eckumlenkung zeigt, die an einem Flügel angeordnet ist, der die genannte umlaufende Nut mit Hinterschneidungen aufweist. Der dortige Winkelkasten (Bezugszeichen 18, mit horizontalem Schenkel 19 nach dortigen Bezugszeichen) wird horizontal in die Nut eingeschoben und mit einem U-förmigen Bügel (dort 39) an der senkrecht dazu verlaufenden hinterschnittenen Nut festgelegt. Gleichzeitig greift er in eine horizontale Nut 35 an dem horizontalen Schenkel (dort 19) ein, womit die Festlegung des dortigen Winkelkastens (als Eckumlenkung) durch Eingriff in hinterschnittene Nuten und durch Festlegung an den senkrecht dazu verlaufenden Nuten im Eckbereich des Profilrahmens erfolgt.In many cases, the profile frame in the region of the sash have a circumferential groove around the sash for receiving the parts of a central closure. In profile frame made of metal or plastic, the grooves have lateral undercuts, can engage in the lateral webs of guiding or holding parts (supporting parts) of the central closure, for mounting the support members are inserted from the ends of the grooves forth in this, then to the to be specified for the installation site, cf. DE-A 29 02 459 (Ferco ), corresponds FR-A 2 415 187 with the local figure 1, which shows the upper corner of a mounting point for a corner drive, which is arranged on a wing having said circumferential groove with undercuts. The local angle box (reference numeral 18, with horizontal leg 19 according to local reference numerals) is inserted horizontally into the groove and fixed with a U-shaped bracket (there 39) at the perpendicular thereto undercut groove. At the same time it engages in a horizontal groove 35 on the horizontal leg (there 19), whereby the determination of the local corner box (as Eckumlenkung) by engaging in undercut grooves and by fixing to the perpendicular grooves in the corner region of the profile frame.

Zum Festlegen der verschiedenen Teile des Zentralverschlusses können auch andere, unterschiedlich ausgebildete Befestigungselemente, insbesondere Schrauben erforderlich sein, so dass die Vorbereitung der Anbringung des Zentralverschlusses ebenso wie die Montage und Festlegung seiner Teile kompliziert und zeitaufwendig sind.To set the various parts of the central closure and other, differently shaped fasteners, in particular screws may be required, so that the preparation of the attachment of the central closure as well as the assembly and fixing of its parts are complicated and time consuming.

Zu den Teilen eines Zentralverschlusses gehören üblicherweise das zentrale Getriebeteil, an dem der zumeist einzige Betätigungshebel angebracht ist, eine oder mehrere Eckumlenkungen, über welche die Betätigungshübe des Betätigungshebels von einer Flügelseite auf die angrenzenden Flügelstirnseiten übertragen werden können, Ausstellarme zur Halterung und Führung des Flügels während der Öffnungsbewegungen, Verschließelemente, die zum Verriegeln des Flügels in der Schließstellung dienen, sowie weitere Teile, wie Ecklager, die ein Schwenken des Flügels um eine seiner Seiten, meistens der Unterkante, ermöglichen. Die einzelnen Teile des Zentralverschlusses weisen dabei jeweils Tragglieder auf, mit denen die Teile am Flügel befestigt werden können und die zur Führung oder Lagerung von längsverschieblichen oder schwenkbaren Teilen des Beschlages dienen. Überall dort, wo ein Befestigungselement den Verschiebeweg der beweglichen Teile des Zentralverschlusses kreuzt, wird in dem verschieblichen Teil ein Langloch in der Länge des Verschiebeweges vorgesehen, durch welches das Befestigungselement hindurchgreift.The parts of a central closure usually include the central gear part, to which the mostly single operating lever is attached, one or more corner deflections, via which the operating strokes of the actuating lever can be transmitted from a wing side to the adjacent wing end faces, Ausstellarme for holding and guiding the wing during the opening movements, closing elements, which serve to lock the wing in the closed position, as well as other parts, such as corner bearings, which allow pivoting of the wing about one of its sides, usually the lower edge. The individual parts of the central closure in this case each have support members with which the parts can be attached to the wing and serve to guide or support of longitudinally displaceable or pivotal parts of the fitting. Everywhere over there, where a fastener crosses the displacement of the moving parts of the central closure, a slot in the length of the displacement path is provided in the displaceable part, through which engages the fastener.

Es ist Aufgabe der Erfindung, einen Zentralverschluß der angegebenen Art so weiterzuentwickeln, daß dessen Montage und Festlegung wesentlich einfacher und zeitsparender erfolgen kann. Dabei sollen die bei einer späteren Betätigung des Zentralverschlusses aufgewendeten Kräfte zuverlässig am Rahmen aufgenommen werden können.It is an object of the invention to develop a central closure of the specified type so that its installation and fixing can be done much easier and faster. The forces expended in a later operation of the central closure should be able to be reliably absorbed on the frame.

Diese Aufgabe wird mit Anspruch 1 oder Anspruch 14 gelöst.This object is achieved with claim 1 or claim 14.

Aufgrund dieser Ausbildung kann bei der Montage zum Beispiel für die Oberkante eines Flügels (die obere Stirnseite) zunächst das Tragglied einer Ausstellschere mit seinen seitlichen Stegen vom Ende der Nut in diese eingeschoben werden. Das Tragglied wird so weit eingeschoben, daß der in ihm geführte Treibstangenabschnitt noch aus der Flügelecke hervorsteht; er wird mit einem formschlüssig eingreifenden Zapfenelement einer anzuordnenden Eckumlenkung, bzw. des in der Eckumlenkung verschieblich geführten Umlenkbandes verbunden. Anschließend wird das Eckumlenkungsgehäuse mit seinem oberen Schenkel, der ebenfalls seitliche Stege aufweist, so in die Nut eingeschoben, daß seine Stege in die Hinterschneidung der Nut eingreifen, ebenso wie dies zuvor bei den Stegen des Scherenteils der Fall gewesen ist. Beide Teile werden an der Oberkante des Flügels in die vorbestimmte gegenseitige Stellung gebracht und dann mit einem einzigen Befestigungselement gemeinsam in der Nut festgelegt, insbesondere steckerartig am Nutgrund der Nut (Anspruch 1, Anspruch 14). Bei mehreren Eckumlenkungen erfolgt das entsprechend mehrfach.Due to this design can be inserted with its lateral webs from the end of the groove in this, for example, for the upper edge of a wing (the upper end face), first, the support member of a Ausstellschere during assembly. The support member is inserted so far that the guided in him drive rod portion still protrudes from the wing corner; it is connected to a form-fitting engaging pin element to be arranged corner deflection, or of the displaceably guided in the corner deflection Umlenkbandes. Subsequently, the Eckumlenkungsgehäuse with its upper leg, which also has lateral webs, inserted into the groove, that its webs engage in the undercut of the groove, just as was previously the case with the webs of the scissor member. Both parts are brought to the upper edge of the wing in the predetermined mutual position and then fixed together with a single fastener in the groove, in particular a plug-like groove on the groove (claim 1, claim 14). In the case of several corner deflections, this is done several times.

Dazu kann vorteilhaft das Befestigungselement eine in wenigstens einem der beiden gemeinsam in der Nut festlegbaren Teilen schraubbare Befestigungsschraube sein (Anspruch 1, Anspruch 16), die mit ihrem Endabschnitt am Nutgrund (Grund der Nut) formschlüssig eingreift, z. B. in eine ganz oder teilweise (durch Vorbohren) vorbereitete Ausnehmung.For this purpose, advantageously, the fastener can be screwed in at least one of the two parts which can be fixed together in the groove parts (claim 1, claim 16), which engages positively with its end portion on the groove bottom (bottom of the groove), z. B. in a whole or in part (by pre-drilling) prepared recess.

Zur gemeinsamen Festlegung weisen die Gehäuseteile bzw. Tragteile der beiden gemeinsam festzulegenden Teile Abschnitte auf, die in der vorgegebenen Stellung einander überlappen (Anspruch 3), wobei die Teile im Bereich dieser Überlappungsstelle (in Quer- oder Längsrichtung) bevorzugt formschlüssig miteinander verbindbar sind (Anspruch 12,13).For common definition, the housing parts or supporting parts of the two parts to be jointly determined on sections that overlap in the predetermined position each other (claim 3), wherein the parts in the region of this overlap point (in the transverse or longitudinal direction) are preferably positively connected to each other (claim 12:13).

Die Eingriffsstelle des Befestigungselementes, insbesondere der Befestigungsschraube, kann an der Überlappungsstelle beide Abschnitte durchdringen und sie damit kraft- oder formschlüssig miteinander verbinden.The point of engagement of the fastening element, in particular the fastening screw, can penetrate both sections at the overlapping point and thus connect them to one another in a non-positive or positive fit.

Die formschlüssige Verbindung kann aber auch in Richtung des Verschiebeweges der Treibstangen gegenüber der Eingriffsstelle des Befestigungselementes versetzt sein, so daß mittels des Befestigungselementes nur zum Beispiel die Eckumlenkung direkt in der Nut - gegen Längsverrückung - formschlüssig festgelegt wird, während die Festlegung des anderen Teils über eine im Abstand davon liegende formschlüssige Verbindung erfolgt (Anspruch 5).The positive connection can also be offset in the direction of the displacement of the drive rods relative to the engagement point of the fastener, so that by means of the fastener, for example, the corner directly in the groove - against Längsverrückung - is positively fixed, while the determination of the other part of a spaced form-fitting connection takes place (claim 5).

Bei Zentralverschlüssen mit Treibstangen für wenigstens drei Stirnseiten eines Flügels wird es so in besonders vorteilhafter Weise möglich, an einer Stirnseite nur jeweils zwei Befestigungselemente vorzusehen, und zwar nahe den Ecken des Flügels. So reichen insgesamt lediglich drei Befestigungselemente an zwei sich gegenüberliegenden Stirnseiten des Flügels aus, um die Eckumlenkungen und die an diesen Flügelseiten angeordneten Teile des Zentralverschlusses zuverlässig festzulegen (Anspruch 7).In the case of central closures with drive rods for at least three end faces of a wing, it is thus possible in a particularly advantageous manner to provide only two fastening elements on one end face, specifically near the corners of the wing. Thus, a total of only three fasteners on two opposite end sides of the wing from to reliably determine the Eckumlenkungen and arranged on these wing sides of the central shutter (claim 7).

In besonderen Fällen ist es nicht einmal erforderlich, eine besondere Ausnehmung für den Eingriff des Endes des Befestigungselementes am Nutengrund vorzusehen, da es möglich ist, das freie Ende des Befestigungselementes, insbesondere einer Schraube selbst-lochend auszubilden (Anspruch 6).In special cases, it is not even necessary to provide a special recess for the engagement of the end of the fastening element on the groove base, since it is possible to form the free end of the fastening element, in particular a self-piercing screw (claim 6).

Alle bei der Betätigung des Zentralverschlusses auftretenden Kräfte werden bei dieser Anordnung (Anspruch 14) praktisch formschlüssig übertragen und vom Flügelrahmen aufgenommen. Damit wird der zumeist dünnwandige Nutengrund in Richtung seiner Dicke nicht belastet (Anspruch 16). Der Gewindeeingriff erfolgt nicht am Rahmenprofil, sondern an einem der Führungsgehäuse oder Tragteile. Der Nutengrund wird nur in Längsrichtung der Nut von den Kräften beaufschlagt. Kräfte in anderen Richtungen werden im Bereich der Hinterschneidungen der Nut aufgenommen.All forces occurring in the operation of the central closure are transmitted in this arrangement (claim 14) practically positive fit and received by the casement. Thus, the mostly thin-walled groove bottom in the direction of its thickness is not charged (claim 16). The thread engagement does not take place on the frame profile, but on one of the guide housing or supporting parts. The groove bottom is acted upon only in the longitudinal direction of the groove by the forces. Forces in other directions are absorbed in the area of the undercuts of the groove.

Die vor der beanspruchten Erfindung noch nötige Vielzahl von Befestigungselemente wird durch überwiegend nur zwei, drei oder vier Befestigungsschrauben mit steckerartigem Eingriff ersetzt. Damit entfallen auch zahlreiche Langlöcher für den Durchtritt von Befestigungselementen in den Treibstangenabschnitten.The still required before the claimed invention plurality of fasteners is replaced by predominantly only two, three or four mounting screws with plug-like engagement. This also eliminates numerous slots for the passage of fasteners in the drive rod sections.

Die beiden Scherenteile 13 sind jeweils wieder über einen Treibstangenabschnitt 4 antriebsmäßig miteinander gekuppelt, und zwar über formschlüssige Kupplungselemente 5.The central closure 1 according to FIG. 1 has, on a vertical end face of the wing, an actuating gear 2 for displacing the displaceable driving rods 4 of the central closure. The actuation takes place by means of a conventional rotary or pivoting lever 3. The displaceable in opposite directions output members 2a, 2b of the transmission 2 are each coupled via positive coupling elements 5 with drive rod sections 4, which are arranged in a circumferential profile of the sash. With its other end, the drive rod sections 4 are also coupled via positive coupling elements with one end of a displaceable Eckumlenkelementes, which is guided in a housing of the corner 6. The housing has a vertical leg 7 and a horizontal leg 8. In the example shown, only the horizontal leg 8 has lateral webs 32a with which the housing of the corner drive 6 can be inserted into the groove from the groove end, engaging in an undercut. At the top of the wing support members 12 are provided in the example shown for scissor-like extension arms 13, wherein each support member 12 also has lateral webs for engaging in the undercut of the groove on the wing. The two scissors parts 13 are in each case drivenly coupled to one another via a drive rod section 4, specifically via positive coupling elements 5.

Die Anordnung an der Unterseite des Flügels kann entsprechend sein. Im vorliegenden Falle können zusätzlich zu dem horizontalen Schenkel der unteren Eckumlenkung 6a jeweils zwei weitere Führungs- oder Tragteile 15 mit Schließ- oder Verriegelungselementen oder dergleichen oder für weitere Ausstellarme vorgesehen sein. Die beiden Teile 15 sind wiederum mit einem Treibstangenabschnitt 4 antriebsmäßig gekuppelt.The arrangement on the underside of the wing may be appropriate. In the present case, two further guide or support members 15 may be provided with locking or locking elements or the like or for further opening arms in addition to the horizontal leg of the lower corner drive 6a. The two parts 15 are in turn drivingly coupled to a drive rod section 4.

Auf der dem Betätigungsgriff gegenüberliegenden vertikalen Stirnseite ist ein über eine weitere untere Eckumlenkung 6b verschiebbarer Treibstangenabschnitt 4 vorgesehen, der zum Beispiel Verriegelungselemente zum Verriegeln des Flügels in der Schließstellung aufweist. Auch die Führungs- oder Tragteile 15 an der Unterseite des Flügels weisen seitliche Stege zum Eingreifen in die Hinterschneidung der Nut an der Unterseite des Flügels auf. Statt der (rechten unteren) Eckumlenkung 6b kann auch eine weitere (teilweise strichliniendargestellte) obere rechte Eckumlenkung 6c vorgesehen sein. Sie kann in gleicher Weise den vertikalen Treibstangenabschnitt 4 steuern, ohne daß die untere rechte Eckumlenkung 6b erforderlich ist. Damit können jeweils drei Eckumlenkungen 6, 6a, 6b oder 6, 6a, 6c für eine vollumfängliche Steuerung an allen vier Stirnseiten des Flügels sorgen, seien dies Scherenelemente (oben), Riegelelemente (unten), Getriebesteuerung (links) oder weitere Riegelelemente (rechts). Die dargestellten jeweils drei Eckumlenkungen für die Betätigung von Treibstangenabschnitten auf allen vier Stirnseiten des Zentralverschlusses kann um eine weitere Eckumlenkung ergänzt werden, um an allen vier Ecken des Flügels in den Eckbereichen Fixierpunkte zu haben, die jeweils durch ein in den Nutgrund steckerartig eingreifendes Sperrelement festlegbar sind, ohne daß es zusätzlicher Schrauben oder Spannvorrichtungen bedürfen würde. Die Anordnung der vierten Eckumlenkung erfolgt gemäß einem weiter hinten beschriebenen Ausführungsbeispiel mit verkürzten Stegabschnitten an einem Schenkel zumindest eines der beschriebenen vier Eckumlenkungen des Zentralverschlusses.On the opposite side of the actuating handle vertical end over a further lower corner 6b displaceable drive rod section 4 is provided which has, for example, locking elements for locking the wing in the closed position. Also, the guide or support members 15 on the underside of the wing have lateral webs for engaging in the undercut of the groove on the underside of the wing. Instead of the (lower right) corner drive 6b, a further (partially dash-lined) upper right corner drive 6c can also be provided. It can control the vertical drive rod section 4 in the same way without the lower right corner drive 6b being required. In this way, three corner deflections 6, 6a, 6b or 6, 6a, 6c can provide full control on all four end faces of the wing, whether scissor elements (top), locking elements (bottom), transmission control (left) or other locking elements (right) , The illustrated three Eckumlenkungen for the operation of espagnolette sections on all four end faces of the central closure can be supplemented by a further Eckumlenkung to have at all four corners of the wing in the corner fixation points, each of which can be fixed by a plug-like manner in the groove bottom locking element without the need for additional screws or fixtures. The arrangement of the fourth corner deflection takes place according to a further embodiment described below with shortened web portions on a leg of at least one of the described four corner deflections of the central closure.

Zur Montage und Festlegung der verschiedenen Teile ist bei diesem Beschlag vorgesehen, daß die Gehäuse- bzw. Tragteile benachbarter Beschlagteile an der oberen Stirnseite 9 und an der unteren Stirnseite 10 des Flügels sich überlappende Abschnitte aufweisen und mit Hilfe eines einzigen Befestigungselementes 14 oder 35 jeweils gemeinsam am Grund der Nut des Flügelrahmens festgelegt werden können. Bei dem Zentralverschluß nach Figur 1, der bewegliche Teile an allen vier Seiten des Flügels aufweist, können somit alle wesentlichen Beschlagteile an Oberrand 9 und Unterrand 10 des Flügels mit insgesamt vier Befestigungsschrauben montiert und festgelegt werden, wobei die Schrauben nahe der Flügelecken angeordnet sind und eine formschlüssige Verbindung zwischen den Beschlagteilen und dem Flügelrahmen bewirken.For mounting and fixing the various parts is provided in this fitting that the housing or supporting parts of adjacent fitting parts on the upper end face 9 and on the lower end face 10 of the wing have overlapping portions and with the help of a single fastener 14 or 35 together can be set at the bottom of the groove of the sash. In the central closure of Figure 1, which has moving parts on all four sides of the wing, thus all the essential fittings can be mounted and fixed to the upper edge 9 and lower edge 10 of the wing with a total of four mounting screws, the screws are arranged near the wing corners and cause a positive connection between the fitting parts and the sash.

In Figur 2 sind zwei typische Rahmenprofile aus Kunststoff oder Metall im Querschnitt dargestellt. Der Blendrahmen ist mit 20 und der Flügelrahmen mit 21 bezeichnet. Zwischen beiden liegt der Flügelfalz 22, in dem das Profil eine Nut 23 vorsieht, die um den ganzen Flügel umläuft und auf beiden Nutenseiten Hinterschneidungen 24 aufweist. Man erkennt die Überlappungsstelle zwischen dem Schenkel 8 des Gehäuses der Eckumlenkung 6 und dem Tragteil 12 der Ausstellschere 13. Im Bereich der Überlappungsstelle greift die Stiftschraube 35 bzw. die Befestigungsschraube 35 ein, die mit ihrem Gewinde in wenigstens einem der beiden Überlappungsabschnitte schraubbar ist, während ihr Ende ohne Schraubgewinde in eine Ausnehmung 50 am Grund der Nut formschlüssig eingreift.In Figure 2 , two typical frame profiles made of plastic or metal are shown in cross section. The frame is designated 20 and the sash frame 21. Between the two is the Flügelfalz 22, in which the profile provides a groove 23 which rotates about the entire wing and on both sides of the groove undercuts 24 has. The overlapping point between the leg 8 of the housing of the corner drive 6 and the support part 12 of the opening shears 13 can be seen. In the region of the overlapping point, the stud 35 or the fastening screw 35 engages, which can be screwed with its thread in at least one of the two overlapping sections their end without screw thread in a recess 50 at the bottom of the groove positively engages.

Die Einzelheiten der Ausbildung sind noch besser in Figur 3 zu erkennen. Die der Eckumlenkung 6 entsprechenden Gehäuse der Eckumlenkungen 30 und 52 nach Figur 3 weisen unterschiedlich ausgebildete Schenkel auf. Der Schenkel 31 ist jeweils der vertikalen Flügelseite und der Schenkel 32 der horizontalen Flügelseite zugeordnet. Der Schenkel 32 und nur dieser weist jeweils seitliche Stege 32a auf, die zum Eingreifen in die Hinterschneidungen 24 der Nut 23 von Figur 2 vorgesehen sind. In Figur 3 ist ein Teil 46 des Profils wiedergegeben, welches die Nut 47 sowie die Hinterschneidungen 48 bildet. Der Nutengrund 49 trägt eine im Nutengrund vorgefertigte Ausnehmung 50 für den Eingriff eines Endes 37 der schraubenförmigen Befestigung 35. Am Ende des Schenkels 32 ist ein Befestigungsabschnitt 33 fest angebracht, in dem eine Gewindebohrung 34 für einen Gewindeabschnitt 36 der Befestigungsschraube 35 vorgesehen ist. Mit 38 ist ein an der Oberkante des Flügels angrenzender weiterer Beschlagteil mit einem Ausstellarm 41 bezeichnet, der an seinem Tragteil 39 bei 42 schwenkbar angelenkt ist. Der Tragteil führt in seinem Inneren ein längsverschiebliches Kraftübertragungselement 44, vom Wesen her auch ein Treibstangenabschnitt, das an seinem frei vorstehenden Ende eine Kupplungsöffnung 45 aufweist, in die im zusammengebauten Zustand ein Zapfen eingreift, ähnlich des dargestellten Zapfens 51 der unteren Eckumlenkung 52. Der Zapfen besitzt an einem Ende eines in dem Eckumlenkungsgehäuse verschieblichen Kraftumlenkungsbandes, das im Bereich des anderen Schenkels ein weiteres, um 90° versetzt orientiertes Kupplungselement zur formschlüssigen Verbindung mit dem Treibstangenabschnitt 4 an der vertikalen Flügelseite aufweist. In Figur 3 erkennt man auch die seitlichen Stege 40 des Tragteils 39, mit dem dieser in die Hinterschneidungen 48 der Nut 47 eingreift. Der Tragteil weist eine Bohrung 43 für den Durchtritt des Abschnittes 37 der Befestigungsschraube 35 auf, während das Kraftübertragungselement 44 in diesem Bereich ein in der Länge dem maximalen Verschiebeweg entsprechendes Langloch aufweist.The details of the training can be seen even better in Figure 3 . The Eckumlenkung 6 corresponding housing of Eckumlenkungen 30 and 52 of Figure 3 have differently shaped leg. The leg 31 is associated with each of the vertical wing side and the leg 32 of the horizontal wing side. The leg 32 and only this has each lateral webs 32a, which are provided for engagement in the undercuts 24 of the groove 23 of Figure 2. FIG. 3 shows a part 46 of the profile which forms the groove 47 and the undercuts 48. The groove bottom 49 carries a recess 50 prefabricated in the groove base for engagement of one end 37 of the helical attachment 35. At the end of the leg 32, a fastening portion 33 is fixed, in which a threaded bore 34 is provided for a threaded portion 36 of the fastening screw 35. With 38 adjacent to the upper edge of the wing further fitting part is denoted by a stay arm 41 which is pivotally connected to its support member 39 at 42. The support member carries in its interior a longitudinally displaceable force transmission element 44, in essence, also an espagnolette section which has a coupling opening 45 at its free projecting end into which a pin engages in the assembled state, similar to the illustrated pin 51 of the lower corner drive 52. The pin has at one end of a displaceable in the Eckumlenkungsgehäuse Kraftumlenkungsbandes having in the region of the other leg another, offset by 90 ° oriented coupling element for positive connection with the drive rod section 4 on the vertical wing side. In Figure 3 can be seen also the lateral webs 40 of the support member 39, with which this engages in the undercuts 48 of the groove 47. The support member has a bore 43 for the Passage of the portion 37 of the fastening screw 35, while the force transmission element 44 has in this area a length corresponding to the maximum displacement path elongated hole.

Entsprechend ist die Anordnung an der Unterkante des Flügels, wobei die dortige Eckumlenkung 52 spiegelbildlich zu der Eckumlenkung 30 angeordnet ist. Das benachbarte Beschlagteil 53 weist ein Führungsgehäuse 54 für ein längsverschiebliches Kraftübertragungselement 56 auf, das an seinem Ende eine Ausnehmung 57 zum kuppelnden Eingriff mit dem Zapfen 51 der Eckumlenkung aufweist. Hier ist das Langloch 58 in dem längsverschieblichen Element 56 sichtbar. Das längsverschiebliche Element kann ein Verriegelungszapfen oder ein anderes aktives Element 59 des Zentralverschlusses aufweisen. Auch hier überlappen sich der Endabschnitt 33 des horizontalen Schenkels der Eckumlenkung und das Ende des Gehäuses 54 im ausreichenden Maße, um den Durchtritt der Befestigungsschraube 35 durch beide zu ermöglichen. Im zusammengebauten Zustand greift das Ende 37 der Schraube jeweils formschlüssig in die Öffnung 50 am Grund 49 der Nut 47 ein. Das Gehäuse 54 weist ebenfalls seitliche Stege 55 zum Eingreifen in die Hinterschneidungen der Profilnut auf. Durch den Eingriff in die Hinterschneidung erfolgt eine formschlüssige Festlegung der Teile in allen Richtungen senkrecht zur Verschieberichtung der Treibstangenabschnitte. Kräfte, die in Verschieberichtung wirken, werden formschlüssig durch den Eingriff des Befestigungselementes 14 in die Ausnehmungen 34 und 43 bzw. 50 aufgenommen und ausschließlich in Längsrichtung des Profils auf dieses übertragen.Accordingly, the arrangement is at the lower edge of the wing, wherein the local corner deflection 52 is arranged in mirror image to the Eckumlenkung 30. The adjacent fitting part 53 has a guide housing 54 for a longitudinally displaceable force transmission element 56, which has at its end a recess 57 for coupling engagement with the pin 51 of the Eckumlenkung. Here, the slot 58 in the longitudinally displaceable element 56 is visible. The longitudinally displaceable element may comprise a locking pin or other active element 59 of the central closure. Again, the end portion 33 of the horizontal leg of the corner and the end of the housing 54 overlap sufficiently to allow the passage of the fastening screw 35 through both. In the assembled state, the end 37 of the screw engages in a form-fitting manner in the opening 50 at the bottom 49 of the groove 47. The housing 54 also has lateral webs 55 for engaging in the undercuts of the profile groove. By engaging in the undercut takes place a positive fixing of the parts in all directions perpendicular to the direction of displacement of the drive rod sections. Forces acting in the direction of displacement are positively received by the engagement of the fastening element 14 in the recesses 34 and 43 or 50 and transmitted exclusively in the longitudinal direction of the profile on this.

In den beschriebenen Beispielen durchgreift das Befestigungselement die sich überlappenden Abschnitte der benachbarten Beschlagteile, wodurch die benachbarten Teile über das Befestigungselement formschlüssig miteinander verbunden sind. Bei der Ausführungsform nach Figur 4 wird lediglich der eine der beiden gemeinsam in der Nut festlegbaren Beschlagteile mit Hilfe des dort vorgesehenen Befestigungselementes 64 formschlüssig in der Bohrung 61 des Nutengrundes 60 festgelegt. Dazu weist zum Beispiel der Befestigungsabschnitt 62 des horizontalen Schenkels der Eckumlenkung eine Gewindebohrung 63 auf, in der das Gewinde 65 des Befestigungselementes 64 schraubbar ist. Zur formschlüssigen Verbindung der beiden benachbarten Beschlagteile ist im Abstand von der Eingriffsstelle der Befestigungsschraube 64 eine Überlappungsstelle 67 zwischen dem Abschnitt 62 und dem benachbarten Teil 68 des Zentralverschlusses vorgesehen, die für einen gegenseitigen formschlüssigen Eingriff ausgebildet sind.In the examples described, the fastening element passes through the overlapping portions of the adjacent fitting parts, whereby the adjacent parts are positively connected to one another via the fastening element. In the embodiment according to FIG. 4 , only one of the two fitting parts that can be fixed together in the groove is fastened in a form-fitting manner in the bore 61 of the groove base 60 with the aid of the fastening element 64 provided there. For this purpose, for example, the attachment portion 62 of the horizontal leg of the corner drive on a threaded hole 63 in which the thread 65 of the fastener 64 is screwed. For the positive connection of the two adjacent fitting parts, an overlapping point 67 between the portion 62 and the adjacent part 68 of the central closure is provided at a distance from the point of engagement of the fastening screw 64, which are designed for a mutual positive engagement.

Die Montage des Zentralverschlusses ist generell einfach und zeitsparend. So können zunächst an der Oberseite die beiden Scherenteile 13 nach Ankuppeln des Treibstangenabschnittes 4 vom Ende der Nut in diese eingeschoben werden, wobei die seitlichen Stege in die Hinterschneidungen eingreifen. Danach wird der obere Schenkel 8 der Eckumlenkung - nach Kuppeln seines Treibstangenabschnitts - mit den Stegen 32a in die Hinterschneidungen vom Ende der Nut her eingeschoben. Vor Erreichen der Endstellung erfolgt die Kupplung mit den an der vertikalen Seite des Flügels liegenden und dort wartenden Treibstangenabschnitten 4. Dann wird die Eckumlenkung in die endgültige Stellung gebracht, in der sich das Gehäuse 8 und der Tragteil 12 entsprechend überlappen, so daß das Befestigungselement 35 in den Schenkel der Eckumlenkung eingeschraubt werden kann, bis sein Endabschnitt in die Bohrung 50 des Nutengrundes eingreift. Zur Festlegung am anderen Ende kann die Befestigungsschraube 14 in den Tragteil der rechten Schere eingeschraubt werden, bis auch deren Ende in die Bohrung des Nutengrundes eingreift. Die Montage an der unteren Seite des Flügels kann entsprechend erfolgen. Ein Problem dabei kann entstehen, wenn die Eckumlenkung am rechten unteren Ende der Figur 1 eingebracht werden soll. Wenn angenommen wird, daß die sonstigen Beschlagteile der unteren Seite von links in die Nut eingeschoben worden sind, so muß die rechte Eckumlenkung von rechts her in Figur 1 in die Nut eingeschoben werden. Hier kann ein Kuppeln der die Kraft übertragenden Elemente der beiden benachbarten Beschlagteile problematisch sein. Das Problem könnte behoben werden, indem ein besonders langer Hub, länger als für die Betätigung des Beschlages notwendig, vorgesehen wird, um die Kupplung zu ermöglichen, bevor die Eckumlenkung mit den Stegen in die Hinterschneidung eingeschoben wird.The assembly of the central closure is generally simple and time-saving. Thus, the first two parts of the scissors 13 can be inserted after coupling the drive rod section 4 from the end of the groove in this at the top, wherein the lateral webs engage in the undercuts. Thereafter, the upper leg 8 of the Eckumlenkung - after coupling its drive rod portion - is inserted with the webs 32a in the undercuts from the end of the groove ago. Before reaching the end position, the coupling takes place with lying on the vertical side of the wing and there waiting drive rod sections 4. Then the corner deflection is brought into the final position in which the housing 8 and the support member 12 overlap accordingly, so that the fastener 35th can be screwed into the leg of the corner deflection, until its end portion engages in the bore 50 of the groove bottom. Laying down at the other end, the fastening screw 14 can be screwed into the supporting part of the right scissors until its end engages in the bore of the groove bottom. The mounting on the lower side of the wing can be done accordingly. A problem can arise when the corner drive at the bottom right end of Figure 1 is to be introduced. If it is assumed that the other fitting parts of the lower side have been inserted from the left into the groove, the right corner guide must be inserted from the right in Figure 1 into the groove. Here, a coupling of the force-transmitting elements of the two adjacent fitting parts can be problematic. The problem could be solved by providing a particularly long stroke, longer than necessary for the operation of the fitting, to allow the coupling before the corner drive with the webs is inserted into the undercut.

Werden die in die Hinterschneidungen eingreifenden Stege am horizontalen Schenkel der Gehäuse der Eckumlenkung um einen Betrag "b" gemäß Figur 3 gekürzt, so enden die Stege 32a in einem erheblichen Abstand vor dem freien Ende des Schenkels 32. Die Länge des Abstands b ist abgestimmt auf die normale Länge des Verschiebeweges c der Treibstangen. Durch die Verkürzung der Stege kann die Eckumlenkung zunächst in eine Überlappung entsprechend der Länge b mit der Flügelecke gebracht werden, ohne in die Hinterschneidung der Nut einzugreifen. Wird nun der normale Schubweg der Treibstangen ausgenutzt, so kann die Kupplung des beweglichen Elementes der Eckumlenkung mit dem beweglichen Element des benachbarten Beschlagteils ohne weiteres im Bereich der Nut erfolgen, worauf die Eckumlenkung in die Nut abgesenkt und dann über den Restweg unter Eingreifen der Stege 32a in die Hinterschneidung in die endgültige Stellung in Richtung der Nut verschoben wird, worauf die Befestigungsschraube eingebracht werden kann.If the webs engaging in the undercuts are shortened on the horizontal leg of the housing of the corner drive by an amount "b" according to FIG. 3 , the webs 32a end at a considerable distance in front of the free end of the leg 32. The length of the distance b is tuned to the normal length of the displacement path c of the drive rods. By shortening the webs, the corner deflection can first be brought into an overlap corresponding to the length b with the wing corner, without interfering with the undercut of the groove. Now, if the normal thrust of the drive rods exploited, the coupling of the movable element of the corner can easily be done with the movable element of the adjacent fitting part in the groove, whereupon the corner deflection lowered into the groove and then over the remaining distance by engaging the webs 32 a is moved into the undercut in the final position in the direction of the groove, whereupon the fastening screw can be introduced.

Dieser Beschlag ist außerordentlich schnell und einfach zu montieren und bietet eine besonders günstige Aufnahme aller auftretenden Kräfte ohne übermäßige Schwächung der Beschlagteile oder ohne die Gefahr eines Ausbrechens des Profilmaterials des Flügelrahmens.This fitting is extremely fast and easy to install and offers a particularly favorable absorption of all occurring forces without excessive weakening of the fittings or without the risk of breaking out of the profile material of the casement.

Mit verkürzten Stegen können alle Eckumlenkungen oder nur eine einzelne ausgerüstet sein, die dann speziell für die zuletzt zu montierende Eckumlenkung eingesetzt wird.With shortened webs, all corner bends or only a single one can be equipped, which is then used especially for the last to be installed corner drive.

Die Öffnungen 50 am Nutengrund brauchen nicht vorgefertigt zu werden, wenn das Ende 37 der Schraubelemente selbstschneidend ausgebildet ist.The openings 50 at the bottom of the groove need not be prefabricated when the end 37 of the screw is self-tapping.
