Ein in der EP 0 179 002 A (übersetzte Patentschrift E 32 767 B) beschriebener Schließautomat dieser Art hat ein an der Türoberseite befestigtes Gehäuse, in dem eine vertikal ausgerichtete Welle für einen Schwenkhebel gelagert ist. In dem Schwenkhebel ist eine Stange verschiebbar gelagert, deren freies Ende in ein an der Tür- oder Fensterzarge befestigtes Gleitstück eingreift, derart, dass beim Öffnen und Schließen des Flügels das Stangenende translatorisch in dem Gleitstück verschoben wird, wodurch der Schwenkarm bzw. Schwenkhebel verschwenkt wird. Die Welle trägt innerhalb des Gehäuses ein Ritzel, das mit einer horizontal ausgerichteten, federbelasteten Zahnstange kämmt, derart, dass beim Öffnen der Tür die Feder vorgespannt wird, um zum Schließen des Flügels diese Kraft wieder abzugeben. Um den Flügel in der Öffnungsstellung zu halten, ist eine Rasteinrichtung vorgesehen, die den Flügel gegen ein automatisches Schließen unter dem Einfluss des vorgespannten Federelementes zu sichert. Ein Nachteil dieses Schließautomaten besteht darin, dass in bzw. an dem Tür- bzw. Fensterflügel für die horizontal ausgerichtete Stelleinrichtung, bestehend im wesentlichen aus dem Zahnritzel, der Zahnstange und dem Federelement, ein relativ großer Platzbedarf besteht.An Indian EP 0 179 002 A (translated Patent E 32 767 B) described closing machine of this type has a fixed to the door top housing in which a vertically aligned shaft is mounted for a pivoting lever. In the pivot lever, a rod is slidably mounted, the free end engages in a fixed to the door or window frame slider, such that when opening and closing the wing, the rod end is translationally displaced in the slider, whereby the pivot arm or pivot lever is pivoted , The shaft carries within the housing a pinion, which meshes with a horizontally oriented, spring-loaded rack, such that upon opening the door, the spring is biased to release this force to close the wing again. In order to hold the wing in the open position, a locking device is provided which secures the wing against automatic closing under the influence of the prestressed spring element. A disadvantage of this locking machine is that in or on the door or window wing for the horizontally oriented adjusting device, consisting essentially of the pinion, the rack and the spring element, a relatively large amount of space is required.

Figur 1 zeigt in schematischer Darstellung eine Tür- oder Fensterzarge A, in deren oberen, horizontal ausgerichteten Zargenabschnitt ein Stellorgan in Form eines vertikal ausgerichteten Zapfens 1 eingesetzt ist. An der Oberseite des um die Angel B verschwenkbaren Tür- oder Fensterflügels C ist der in Figur 3 dargestellte Schließautomat befestigt, von dem in Figur 1 nur der mit dem Stellorgan 1 zusammenwirkende Schwenkhebel 2 dargestellt ist. Der Schwenkhebel 2 ist starr an einer Welle 5 befestigt, die im Einbauzustand des Schließautomats in einen Tür- oder Fensterflügel C eine vertikal Schwenkachse für den Schwenkhebel 2 bildet. FIG. 1 shows a schematic representation of a door or window frame A, in whose upper, horizontally oriented frame portion, an actuator in the form of a vertically oriented pin 1 is used. At the top of the pivotable around the Angel B door or window sash C is the in FIG. 3 fastener shown attached from the in FIG. 1 only the cooperating with the actuator 1 pivot lever 2 is shown. The pivot lever 2 is rigidly attached to a shaft 5, which forms a vertical pivot axis for the pivot lever 2 in the installed state of the lock in a door or window sash C.

Der Schwenkhebel 2 ist an seinem freien Ende gabelförmig mit zwei unterschiedliche Längen aufweisende Gabelzinken 2.1, 2.2 ausgebildet, zwischen denen im geschlossenen Zustand des Fenster- oder Türflügels C der Zapfen 1 liegt.The pivot lever 2 is fork-shaped at its free end with two different lengths forks 2.1, 2.2, between which in the closed state of the window or door leaf C of the pin 1 is located.

Gemäß Figur 2 ist der Schließautomat mittels eines Stulps 3 an bzw. in dem Flügel C befestigt, der zu diesem Zweck mit einer den Schließautomaten aufnehmenden Bohrung versehen ist.According to FIG. 2 the closing machine is attached by means of a forend 3 to or in the wing C, which is provided for this purpose with a bore receiving the automatic closing machine.

Der Schließautomat enthält ein oberes hülsenförmiges Stellglied 8, das im Einbauzustand stationär in dem Flügel C angeordnet ist, z.B. durch Befestigung an dem Stulp 3, sofern ein solcher verwendet wird.The closure machine includes an upper sleeve-shaped actuator 8, which in the installed state is arranged stationarily in the wing C, e.g. by attachment to the forend 3, if one is used.

An das obere hülsenförmige Stellglied 8 schließt ein unteres ebenfalls als Zylinderhülse ausgebildetes Stellglied 7 an, das auf der Welle 5 verschiebbar ist und einen axial verlaufenden Führungsschlitz 7.2, vorzugsweise zwei sich diametral gegenüber liegende Führungsschlitze, aufweist, in den ein an der Welle 5 angebrachter, im wesentlichen radial ausgerichteter Führungsstift 5.1 ragt bzw. in die Führungsstifte ragen. Das untere Stellglied 7 ist auf einem vorzugsweise als Schraubendruckfeder ausgebildeten Federelement 6 abgestützt, das mit seinem unteren Ende auf einem Gegenlager 9 abgestützt ist. Dieses Gegenlager 9 hat vorzugsweise die Form einer Stellmutter, die auf ein am unteren Ende der Welle 5 angebrachtes Gewinde 5.1 aufgeschraubt ist.To the upper sleeve-shaped actuator 8 includes a lower also designed as a cylinder sleeve actuator 7, which is displaceable on the shaft 5 and an axially extending guide slot 7.2, preferably two diametrically opposite guide slots, in which a mounted on the shaft 5, essentially radially aligned guide pin 5.1 protrudes or protrude into the guide pins. The lower actuator 7 is supported on a preferably designed as a helical compression spring element 6, which is supported with its lower end on an abutment 9. This counter-bearing 9 preferably has the shape of an adjusting nut which is screwed onto a thread 5 attached to the lower end of the shaft 5.

Die beiden miteinander fluchtenden Stellglieder 7 und 8 haben im Bereich der sich gegenüberliegenden Enden in radialer und axialer Richtung schräg liegende Gleitflächen 7.1 und 8.1, die so einander zugeordnet sind, dass beim Verschwenken des Schwenkhebels 2 das untere Stellglied 7 relativ zu dem stationären Stellglied 8 in axialer Richtung verschoben wird, derart, dass beim Öffnen des Tür- oder Fensterflügels C das untere Stellglied 7 entgegen der Federkraft des Federelementes 6 nach unten gedrückt wird, wodurch dieses Federelement 6 vorgespannt wird.The two mutually aligned actuators 7 and 8 have in the region of the opposite ends in the radial and axial direction inclined sliding surfaces 7.1 and 8.1, which are associated with each other so that when pivoting the pivot lever 2, the lower actuator 7 is displaced relative to the stationary actuator 8 in the axial direction, such that when opening the door or window sash C, the lower actuator 7 against the spring force of Spring element 6 is pressed down, whereby this spring element 6 is biased.

Der Führungsschlitz 7.2 bzw. die Führungsschlitze und der Führungsstift 5.1 bzw. die Führungsstifte sind so aufeinander abgestimmt, dass ein Verschwenken des Schwenkhebels 2 und dem damit einhergehenden Drehen der Welle 5 das untere Stellglied 7 unter dem Einfluss der miteinander zusammenwirkenden schräg liegenden Gleitflächen 7.1, 8.1 einerseits gedreht und andererseits nach unten gedrückt wird.The guide slot 7.2 or the guide slots and the guide pin 5.1 and the guide pins are coordinated so that pivoting of the pivot lever 2 and the associated rotation of the shaft 5, the lower actuator 7 under the influence of cooperating inclined sliding surfaces 7.1, 8.1 rotated on the one hand and on the other hand pressed down.

Beim handbetätigten Öffnen des Tür- oder Fensterflügels C wird der Schwenkhebel 2 von dem zwischen die beiden Gabelzinken 2.1, 2.2 eingreifenden Zapfen 1 aus seiner Ruhestellung, d.h. aus seiner parallel zur Fenster- oder Türflügelebene liegenden Stellung, in Abhängigkeit von der Länge des kürzeren Gabelzinkens 2.2 vorzugsweise um z.B. 30° nach außen verschwenkt. Diese Schwenkbewegung wird mittels der durch die beiden Stellglieder 7 und 8 gebildeten Einrichtung in eine lineare Bewegung des unteren Stellgliedes 7 umgewandelt. Die Schwenkbewegung des Schwenkhebels 2 endet beim Öffnen des Flügels C dann, wenn der kürzere Gabelzinken 2.2 aus dem Einflussbereich des Zapfens 1 ausgeschwenkt ist und das untere Stellglied 7 soweit relativ zum oberen Stellglied 8 gedreht worden ist, dass die an den äußeren Enden der Schrägflächen 7.1 und 8.1 befindlichen Rastorgane, vorzugsweise in Form von ineinandergreifenden Einbuchtungen 7.3 und Vorsprüngen 8.3, ineinander greifen. Diese Rastorgane bewirken, dass nach der Freigabe des Schwenkhebels 2 von dem Zapfen 1 der Schwenkhebel 2 nicht in seine Ruhestellung zurückgeschwenkt, sondern so lange in dieser Raststellung verbleibt, bis beim Schließen des Tür- oder Fensterflügels C von Hand der längere Gabelzinken 2.1 des Schwenkhebels 2 wieder in den Bereich des Zapfens 1 gelangt und der Schwenkhebel 2, immer noch handbetätigt, aus seiner Raststellung frei gegeben wird; daran anschließend erfolgt das automatische, gedämpfte Zuschwenken des Flügels C unter dem Einfluss der Rückstellkraft des Federelementes 6, wodurch das untere Stellglied 7 gedreht und nach oben geschoben wird und sich dabei gleichzeitig die Welle 5 zum Zurückschwenken des Schwenkhebels 2 in die Ruhestellung dreht.When manually opening the door or window sash C of the pivot lever 2 of the intervening between the two prongs 2.1, 2.2 pin 1 from its rest position, ie from its position parallel to the window or door leaf position, depending on the length of the shorter fork 2.2 preferably pivoted by 30 °, for example, to the outside. This pivotal movement is converted by means of the device formed by the two actuators 7 and 8 in a linear movement of the lower actuator 7. The pivoting movement of the pivot lever 2 ends when the wing C opens when the shorter forks 2.2 is swung out of the sphere of influence of the pin 1 and the lower actuator 7 has been rotated relative to the upper actuator 8 so far that at the outer ends of the inclined surfaces 7.1 and 8.1 located latching organs, preferably in the form of interlocking recesses 7.3 and projections 8.3, engage each other. This locking members cause that after the release of the pivot lever 2 of the pin 1, the pivot lever 2 is not pivoted back into its rest position, but so long remains in this detent position until closing the door or window sash C by hand, the longer fork 2.1 of the pivot lever. 2 again enters the region of the pin 1 and the pivot lever 2, still manually operated, is released from its detent position; this is followed by the automatic, dampened tilting of the wing C under the influence of the restoring force of the spring element 6, whereby the lower actuator 7 is rotated and pushed up and at the same time rotates the shaft 5 for pivoting back of the pivot lever 2 in the rest position.

Die Rastorgane 7.3 und 8.3 entsprechen einer möglichen Lösung, um den Schwenkhebel beim Öffnen der Tür in seiner Raststellung festzuhalten.The locking members 7.3 and 8.3 correspond to a possible solution to hold the pivot lever when opening the door in its locked position.

Gemäß Figur 3 besteht das Federelement 6 aus einer Schraubendruckfeder. Anstelle einer Schraubendruckfeder kann auch eine Gasdruckfeder verwendet werden, die dann entsprechend der Spiraldruckfeder 6 zwischen dem unteren Ende des unteren Stellgliedes 7 und dem entlang des Gewindes 5.1 verstellbaren Gegenlagers 9 abgestützt ist.According to FIG. 3 the spring element 6 consists of a helical compression spring. Instead of a helical compression spring and a gas spring can be used, which is then supported according to the helical compression spring 6 between the lower end of the lower actuator 7 and the adjustable along the thread 5.1 thrust bearing 9.

Die Figuren 5 und 6 zeigen untere und obere zylindrische Stellglieder 10, 11, die an Stelle der in den Figuren 3 und 4 dargestellten Stellglieder 7 und 8 auf der Welle 5 gelagert sind. Das untere, mit mindestens einem dem Axialschlitz 7.2 entsprechenden Axialschlitz 10.2 versehene Stellglied 10 hat im Bereich seines Außenumfangs mindestens einen an Schrägflächen 10.3 anschließenden, axial ausgerichteten Vorsprung 10.1, während in dem Mantel des oberen zweiten Stellgliedes 11 für jeden Vorsprung 10.1 zwei nebeneinander liegende, und Schrägflächen bildende, axial ausgerichtete Einbuchtungen 11.1; 11.2 unterschiedlicher Tiefe angeordnet sind, zwischen denen jeweils ein Rastvorsprung 11.3 liegt.The FIGS. 5 and 6 show lower and upper cylindrical actuators 10, 11, which instead of in the FIGS. 3 and 4 shown actuators 7 and 8 are mounted on the shaft 5. The lower, provided with at least one axial slot 7.2 corresponding axial slot 10.2 actuator 10 has in the region of its outer periphery at least one adjoining inclined surfaces 10.3, axially aligned projection 10.1, while in the shell of the upper second actuator 11 for each projection 10.1 two adjacent, and Inclined surfaces forming, axially aligned indentations 11.1; 11.2 different depths are arranged, between each of which a latching projection 11.3 is located.

Es sind vorzugsweise zwei sich diametral gegenüber liegende Vorsprünge 10.1 und dementsprechend zwei sich diametral gegenüberliegende tiefere Einbuchtungen 11.1 bzw. demgegenüber weniger tiefe Einbuchtungen 11.2 entsprechenden Rastvorsprüngen 11.3 vorgesehen.There are preferably two diametrically opposite projections 10.1 and accordingly two diametrically opposite deeper indentations 11.1 or correspondingly less deep indentations 11.2 corresponding latching projections 11.3 are provided.

Die Anordnung und Funktion dieser beiden Stellglieder 11 und 12 entspricht im Wesentlichen der Anordnung und Funktion der oben im Einzelnen beschriebnen Stellglieder 7 und 8, auf die hiermit Bezug genommen wird.The arrangement and function of these two actuators 11 and 12 substantially corresponds to the arrangement and function of the above-described in detail actuators 7 and 8, to which reference is hereby made.

An automatic closing mechanism according to Claim 2, characterized in that, in the assembled state, the lower end of the spring element (6) is supported on a thrust bearing (9), and in that the lower actuator (7 or 10), which is movable in axial direction, is supported on the upper side of the spring element (6).
  4. An automatic closing mechanism according to Claim 2 or 3, characterized in that the two actuators (7, 8 or 10, 11) take the form of cylindrical sleeves mounted on the shaft.
  5. An automatic closing mechanism according to one of Claims 2 to 4, characterized in that the upper actuator (8 or 11) can be fixed at the upper side of the wing (C), preferably by means of a cuff plate (3), in such a way as to be immobile, and in that the lower actuator (7 or 10) is coupled with the shaft (5) for co-rotation therewith and is mounted on said shaft so as to be displaceable relative to it in axial direction.
  6. An automatic closing mechanism according to Claim 5, characterized in that the lower actuator (7 or 10) has a guide slot (7.2) extending in axial direction, and a guide pin (5.1), attached to the shaft (5) and oriented in substantially radial direction, projects into said guide slot (7.2).
  7. An automatic closing mechanism according to Claim 6, characterized in that the lower actuator has two guide slots (7.2) located diametrically opposite one another, and guide pins (5.1) attached to the shaft (5) project into said guide slots.
  8. An automatic closing mechanism according to one of Claims 2 to 7, characterized in that, at their outer ends, the inclined surfaces (7.1; 8.1) have catching elements in the form of interlocking recesses (7.3) and projections (8.3).
  9. An automatic closing mechanism according to Claim 6 or 7, characterized in that, in the region of its outer circumference, one actuator (10) has at least one projection (10.1) oriented in axial direction, and in that, in the outer surface of the second actuator (11), two recesses (11.1; 11.2) of different depths are provided for each projection, said recesses (11.1; 11.2) lying side by side and extending in axial direction with a catching projection (11.3) located between them.
  10. An automatic closing mechanism according to one of Claims 2 to 8, characterized in that the spring element (6) is a helical pressure spring mounted on the shaft (5), and in that the shaft has a screw thread (5.1) at its lower end for an adjusting nut which constitutes the thrust bearing (9).
  11. An automatic closing mechanism according to one of Claims 2 to 8, characterized in that the spring element is a gas pressure spring.
  12. An automatic closing mechanism according to one of Claims 1 to 11, characterized in that the free end of the swivel lever (2) is fork-shaped with two tines (2.1, 2.2), the adjusting device (1), which takes the form of a vertically oriented stud, being located between said tines when the wing (C) is in its closed position.
  13. An automatic closing mechanism according to Claim 12, characterized in that the fork tines (2.1, 2.2) are of different lengths.
  14. An automatic closing mechanism according to one of Claims 2 to 13, characterized in that the actuators (7, 8), the shaft (5) and the spring element (6) are housed in a protective sleeve (10).
