Definitions

  • the invention relates to a locking device for a door closer, in particular an overhead door closer, with a sliding arm, the fixed frame-side end of which carries a sliding roller which can be displaced in a guide rail, a sliding shoe or the like, a spring-loaded swivel member being mounted on the side of the sliding path of the sliding roller protrudes into the sliding area of the sliding roller or the like and has two oppositely sloping sliding slopes, one behind the other, the sliding roller or the like also being pressed against the second sliding slope by the closing spring of the door closer after the first sliding slope has overrun in the open position to be locked, whereby furthermore, a torque of the locking device acting on the pivoting member in a locking sense exceeds the torque of the door closer acting in a corresponding sense, and finally on a pressure pointing opposite to the second sliding slope Surface or edge of the swivel member a pressure roller or the like.
  • a sliding member mounted on the housing or the like of the device See DE-A-3 806 662.
  • this door closer is simply referred to as an overhead door closer, without this can be understood restrictively - are attached to the door or the upper door end. They have a swivel-mounted extension arm, referred to as a sliding arm, the end of which is remote from the door closer carries a sliding roller, a sliding shoe or the like, which is or is longitudinally displaceably mounted in a guide rail attached to the fixed frame or masonry.
  • the guide rail is preferably parallel to the upper edge of the door. When the door is closed, this sliding arm assumes an approximately parallel or only slightly inclined position to the door plane and thus also to the guide rail plane, while it forms an angle with both when the door is open.
  • Every door closer is to close the door again after the opening force ceases, for example when a person opening the door releases the latter.
  • This locking of the door in an open rotational position can be achieved, for example, with a hydraulic door closer via its hydraulics. If a Hydraullk or comparable device is missing, the determination must be carried out in another way. This also applies if one does not want or cannot use any hydraulic system that may be available for a certain opening angle.
  • a locking device is known from DE-OS 38 06 662, in which the door is locked with the aid of an electromagnet.
  • a second carriage is slidably mounted on a first carriage which is arranged displaceably in a guide rail.
  • the adjustment or adjustment of the locking angle is carried out by positioning and locking the first slide, while locking the door of an open rotational position requires the interaction of the second slide with an electromagnet arranged outside the movement path of the pivoting member on the first slide.
  • the bearing roller cooperating with the movable pivot member is displaced relative to the second slide against a compression spring when the window sash is moved. If, with the electromagnet switched on, the door is pivoted into the closed position under the action of the door closer, the sliding roller cannot pass the pivot member and the door is locked in an open rotational position.
  • the invention is therefore based on the object of providing a door closer with a locking device which, in its basic design, operates purely mechanically, is of robust construction and ensures safe functioning.
  • the object is achieved in that on the sliding link one end of at least one loading spring for the swivel member rests, the other end of which is supported on the housing or the like of the device, and that the pressure roller is held immovably on the sliding member, the locking device torque acting on the swivel member of the locking device at least by the loading spring or springs of the pivot member is generated.
  • This purely mechanical locking device which, like all mechanical devices, is characterized by particular robustness and functional reliability, has a very simple structure and, because only a few parts are necessary, can also be manufactured inexpensively.
  • the device is mounted laterally, for example on the underside of the guide rail, in such a way that its spring-loaded pivoting member in the division of labor projects into the range of motion of the castor. Both must be assigned to each other in such a way that the slide roller is displaced towards the swivel member when the door is opened and, in cooperation with the first sliding slope, swings the swivel member downwards until it can continue to move over the swivel member.
  • the door closer leads it back towards the closed position after the opening force ceases. Now, however, due to the force of the loading spring or springs, the pivot member is again in the displacement area of the returning guide roller. However, due to its now counter-moving movement, it strikes the second slope. The closing force of the door closer is not able to turn the swivel link again in the unlocking sense in the interaction of the sliding roller and the second sliding slope.
  • the moment from the loading spring or springs of the swivel member is namely greater than the moment acting in the opposite direction from the closing force of the door closer.
  • the door remains in the opening position specified by this locking device.
  • it can easily be closed by loading the door leaf in the closing direction by an opposing force, for example by hand.
  • Such a force given up by hand is able, at least in connection with the closing force of the door closer, to overcome the "locking force" of the loading spring or springs or the moment resulting therefrom.
  • the manual force can be dispensed with because the closing force of the door closer is now sufficient to completely close the door.
  • the swivel member is designed as a lever which is rotatably mounted on a base body, housing or the like of the device and which forms the two sliding slopes with at least part of its longitudinal edge, the first sliding slope also being in the working position of the swing member
  • the longitudinal axis of the guide rail forms a larger angle than the second slide-on slope and that the pivoting member is provided with a rear extension and is thus designed as a two-armed lever, the rear extension forming part of a locking device for ineffective pitching, the other part of which is designed as a detent is provided with a snap-in receptacle, wherein the snap-in receptacle can also be brought into the pivoting range of the catch.
  • the sliding roller or the like can be easily moved over the first sliding slope without any special effort are moved away, which is preferably also formed longer than the second, while the second then acts in the manner of a pivotable stop due to its greater inclined position and also the introduction of force with respect to the geometric pivot axis of the pivot member.
  • the sliding roller after a more or less short angle of rotation, seen in the closing direction, hits the second sliding slope, which then causes the closing movement is ended.
  • this locking device is ineffective, ie the door is held in the assigned open position from a certain opening angle when it is released.
  • the locking device can now be overridden for as long as is desired. All that is required is to transfer the snap-in receptacle into an effective position in which it prevents the pivoting member from rotating.
  • the loading spring of the device is relatively strongly tensioned so that it immediately transfers the swivel member into the active position after the latching receptacle has been moved from the range of movement of the latch. From this you can also see that the locking device is held securely in the locked position by the loading spring or springs.
  • Another embodiment of the invention is that the other end of the or each loading spring is supported by a pressure plate on the housing or the like, and the pressure plate is displaceable and lockable is mounted on the housing or the like, the pressure plate being displaceable by means of a screw mounted on the housing or the like.
  • a spring tensioning device can be accommodated well in this pasture, making this device easy to adapt to the respective door closer or a correspondingly heavy door.
  • the pressing surface of the pivot member extends in a further development of the invention in its working position so inclined to the longitudinal axis of the guide rail that it moves the sliding member against the resistance of its loading spring or springs when the pivot member is rotated into an ineffective position.
  • the angle which the pressing surface forms, for example, with a plane running perpendicular to the door plane and to the longitudinal axis of the guide rail is, for example, in the order of 10 to 30 °.
  • this angle and the swivel angle of the swivel member there is a more or less large displacement movement of the slide relative to the device housing or the like, and this then results in a corresponding spring force for resetting this system.
  • the movement of the pivoting member into its working position is expediently locked by a stop, unless this can be achieved in another way, for example by utilizing the guide rail or relaxing the loading spring in the working position.
  • the latching receptacle is located on a latching member which can be displaced transversely to the axis of rotation of the swivel member in the housing or the like and which is in particular provided with a corresponding handle, so that it can be easily removed from the working position can shift the release position and vice versa.
  • the handle can be detachably attached.
  • a further preferred embodiment of the invention consists in that the housing or the like of the device is mounted in a longitudinally displaceable manner on the guide rail or an additional profile connected to it, and can be fixed in any displacement position by means of a fixing device.
  • This not only enables the fixing device to be retrofitted to existing doors, but also allows it to be placed virtually anywhere on the guide rail, so that the door can be locked at any opening angle, at least within wide limits.
  • this can advantageously be combined with the guide rail, as a result of which the assembly effort is reduced and a particularly advantageous optical construction is created.
  • the so-called hidden placement of the locking device on the fixed frame should be mentioned.
  • the current to the electromagnet designed as a holding magnet interrupts, this reduces the torque acting on the swivel member, which converts it into a working position, and the now greater moment acting in the opposite direction can now have an effect from the force of the door closer.
  • the pivot member is depressed by the guide roller and the door is closed.
  • the force of the load spring is also able to move all of the deflected parts of the locking device back into their working position when the door is closed.
  • the opened door can be locked again with this locking device.
  • the door 1 is rotatably mounted on a fixed frame 2. For this purpose, it has at least two rotary bearings 3 arranged one above the other, the upper one of which can be seen in FIG. 1.
  • a door closer 4 is attached, which is consequently designed as a so-called overhead door closer.
  • the end of the sliding arm 6 on the door closer side is coupled in a rotationally fixed manner to the drive shaft of the door closer.
  • a locking device which holds the opened door in the relevant opening position in spite of the closing torque exerted on it by the door closer. Two embodiments of such a locking device are shown in the drawing and are described in detail below.
  • a swivel member 10 which by means of at least one, in the exemplary embodiments but is loaded by two springs 11 in the direction of arrow 12.
  • the axis of rotation of the pivot member 10 is designated 13. From Fig. 3 it can be seen that the pivot member 10 protrudes into the displacement area of the roller 7 in its working position. Here, however, the position of the roller is drawn, which it assumes when the door is locked. When the door is closed, it is much further to the right, ie it is moved along its slideway 15 in the direction of arrow 14 when the door is opened.
  • the pivot member 10 has two oppositely sloping sliding slopes 16 and 17 with respect to the direction of movement 14.
  • the first sliding slope 16 is longer than the second sliding slope 17.
  • the sliding slope 16 closes an angle 56 and the sliding slope 17 in contrast smaller angle 57 a.
  • the sliding roller 7 first reaches the somewhat flatter first sliding slope 16.
  • a sufficiently large hand force when the door is opened causes the pivoting member 10 to rotate counter to the arrow 12 with simultaneous tensioning or stronger tensioning of the loading spring or springs 11
  • load springs are referred to below, without this being intended to be restrictive.
  • the two sliding slopes 16 and 17 merge directly into one another in the exemplary embodiments. As soon as the sliding roller 7 has passed the highest edge 18 of the swivel member 10, this can go back into the working position shown in FIG. 3 due to the force of the springs 11.
  • the pivoting end movement is secured by means of a stop, for example a small pin 19 or the like element, which engages in a corresponding slot, an opening or the like.

  • the hook engages around a pressure roller 22 (FIG. 8).
  • FIG. 8 In the working position of the pivoting member 10 shown in FIG. 3, its pressing surface 23 attached to the hook-like extension 21 extends at an acute angle 24 to an imaginary vertical plane 25 perpendicular to the door plane and to the longitudinal axis of the guide rail 5.
  • the inclined position of the pressing surface 23 in cooperation with the pressure roller 22 causes a lateral displacement of the sliding member 27 in the direction of arrow 28 while rotating the pivoting member 10 against the arrow 12 while simultaneously tensioning the load springs 11.
  • Such a shift occurs when the slide roller 7 is pressed with sufficient force in the direction of arrow 28 against the second sliding surface 17.
  • the two loading springs 11 cause an opposing torque, i.e.
  • the second lever arm of the pivot member 10 forms a rear extension 29. It, or more precisely its free end, forms a catch 30 of a locking device 31.
  • the second part of this locking device forms a catch receptacle 32.
  • This is located on a catch member 33, which in the sense of the double arrow 26 is mounted longitudinally displaceably on the device housing 20.
  • the longitudinal guide is designated by 34 in FIG. 3.
  • the locking member 33 assumes its ineffective position, while it is in its active position in FIG. 8.
  • the catch 30 then engages in the notch-like right part of the catch receptacle 32.
  • the force of the springs 11 can now have no effect, and as a result the locking device is deactivated.
  • a removable handle 35 is coupled in a rotationally fixed manner to the latching member 33 with the aid of its pin-like projection. A screw secures this connection.
  • the handle can optionally be mounted on one of the two ends of the detent member 33. The door closer can therefore be used for both DIN right and DIN left doors.
  • the housing 20 of the device preferably consists of two plate-shaped bodies 37 and 38, which are held together via spacer elements 39 and 40.
  • the former is a riveted-in spacer bolt (FIG. 4), while the spacer element 40 is designed as a riveted-in bushing which has an internal thread 41.
  • the loading springs 11 are inserted in corresponding blind bores of the sliding member 27 and are thereby supported on the sliding member by their left end in the drawing. Their right end lies against a pressure plate 42, which is mounted in the same sense as the sliding member 27 to be longitudinally displaceable on the housing 20 of the device.
  • the free end of an adjusting screw 43 engages on the rear surface of the pressure plate 42 and can be screwed into a crosspiece 44 or the like of the housing 20. With the help of the screw 43, the tension of the springs 11 can thus be adjusted.
  • the guide rail 5 is designed as a cross-sectionally C-shaped rail and is made in one piece with an additional profile 45.
  • the locking device according to the invention is mounted displaceably and lockable. You can assign them to virtually any position on the upper fixed cross member. If it has been brought into the correct position, it is secured with the aid of a fixing device 46 (FIG. 9).
  • a fixing device 46 (FIG. 9).
  • This essentially consists of a clamping plate 47 and a clamping screw 48. The latter passes through a longitudinal slot 49 of the profile rail or the additional profile 45. It is easy to see that the clamping plate 47 can be pressed on the outside of the profile leg 50 by tightening the screw 48 and thereby the locking device according to the invention can be secured against displacement.
  • the corner of the swivel member 10 formed by the two sliding bevels 16 and 17 passes through a profile slot 51 from bottom to top.
  • the plate-shaped body 37 of the device housing 20 is provided with an opening 52. 11, an electromagnet 53 can be used in these. If the sliding member 27 is made of ferromagnetic material or a corresponding plate is attached to the outside, the excited electromagnet 53 pulls the sliding member 27 into the position shown in FIG. 11 and holds it there. This movement is supported in the second embodiment of the invention by the loading springs 11. However, these are set weaker or weaker than in the first embodiment, because both forces together, namely the spring force and the magnetic force, should be approximately the same as the spring force of the variant without Electromagnet. This applies to the same or at least similar closing force of the door closer 4.
  • a current collector 54 is also attached to the device or to its housing 20, which is connected or at least connectable to the electromagnet 53 . It interacts with conductor tracks 55, which are provided on an assembly profile 58. With the help of the latter, the guide rail 5 is mounted directly or indirectly on the fixed frame.
  • the electromagnetic holding force and the force of the springs 11 or the torque resulting therefrom in the direction of arrow 12 outweigh the closing force of the door closer 4 or the resulting torque acting counterclockwise on the pivot member 10. If the current to the electromagnet 53 is interrupted, for example with the aid of a fire or smoke detector, the holding force of the electromagnet 53 is eliminated, and then the torque from the springs 11 is smaller than the counter-torque resulting from the closing force of the door closer, which is why the door closer is now able to press the swivel member 10 against the arrow 12 and close the door via the sliding roller 7.

Description

Die Erfindung beziehtseich auf eine Feststellvorrichtung für einen Türschließer, insbesondere einen Obentürschließer, mit einem Gleitarm, dessen festrahmenseitiges Ende eine in einer Führungsschiene verschiebbare Gleitrolle, einen Gleitschuh od. dgl. trägt, wobei seitlich der Gleitbahn der Gleitrolle ein federbelastetes Schwenkglied gelagert ist, das in den Verschiebebereich der Gleitrolle od. dgl. hineinragt und zwei gegenläufig abfallende, hintereinander liegende Aufgleitschrägen aufweist, wobei außerdem die Gleitrolle od. dgl. nach Oberlaufen der ersten Aufgleitschräge in der zu arretierenden Offenstellung durch die Schließfeder des Türschließers an die zweite Aufgleitschräge angedrückt ist, wobei desweiteren ein in sperrendem Sinne am Schwenkglied wirkendes Drehmoment der Feststellvorrlchtung das in entsprechendem Sinne wirkende Drehmoment des Türschließers übertrifft, und wobei schließlich an einer entgegengesetzt zur zweiten Aufgleitschräge weisenden Andrückfläche oder -kante des Schwenkglieds eine Andrückrolle od. dgl. eines am Gehäuse od. dgl. der Vorrichtung schiebbar gelagerten Schiebeglieds unmittelbar anliegt. Siehe DE-A-3 806 662. Diese Türschließer - der Einfachheit halber wird lediglich noch von einem Obentürschließer gesprochen, ohne daß dies einschränkend verstanden werden darf - werden an der Tür bzw. dem oberen Türende befestigt. Sie besitzen einen drehbar gelagerten, als Gleitarm bezeichneten Ausstellarm, dessen türschließerfernes Ende eine Gleitrolle, einen Gleitschuh od. dgl. trägt, die bzw. der in einer am festen Rahmen oder Mauerwerk angebrachten Führungsschiene längsverschiebbar gelagert ist. Die Führungsschiene erstrecht sich dabei vorzugsweise parallel zur oberen Türkante. Bei geschlossener Tür nimmt dieser Gleitarm eine annähernd parallele oder lediglich leicht geneigte Lage zur Türebene und damit auch zur Führungsschienenebene ein, während er bei geöffneter Tür mit beiden einen Winkel bildet.The invention relates to a locking device for a door closer, in particular an overhead door closer, with a sliding arm, the fixed frame-side end of which carries a sliding roller which can be displaced in a guide rail, a sliding shoe or the like, a spring-loaded swivel member being mounted on the side of the sliding path of the sliding roller protrudes into the sliding area of the sliding roller or the like and has two oppositely sloping sliding slopes, one behind the other, the sliding roller or the like also being pressed against the second sliding slope by the closing spring of the door closer after the first sliding slope has overrun in the open position to be locked, whereby furthermore, a torque of the locking device acting on the pivoting member in a locking sense exceeds the torque of the door closer acting in a corresponding sense, and finally on a pressure pointing opposite to the second sliding slope Surface or edge of the swivel member a pressure roller or the like. A sliding member mounted on the housing or the like of the device. See DE-A-3 806 662. For the sake of simplicity, this door closer is simply referred to as an overhead door closer, without this can be understood restrictively - are attached to the door or the upper door end. They have a swivel-mounted extension arm, referred to as a sliding arm, the end of which is remote from the door closer carries a sliding roller, a sliding shoe or the like, which is or is longitudinally displaceably mounted in a guide rail attached to the fixed frame or masonry. The guide rail is preferably parallel to the upper edge of the door. When the door is closed, this sliding arm assumes an approximately parallel or only slightly inclined position to the door plane and thus also to the guide rail plane, while it forms an angle with both when the door is open.

Die Aufgabe jedes Türschließers ist es, die Tür nach Wegfall der Öffnungskraft, also beispielsweise wenn eine die Tür öffnende Person letztere freigibt, wieder zu schließen. Man ist jedoch nicht grundsätzlich an einem Schließen der Tür interessiert, vielmehr gibt es auch Anwendungsfälle, in denen die Tür in einem gewissen Öffnungswinkel stehen bleiben soll. Dieses Feststellen der Tür in einer geöffneten Drehlage kann man beispielsweise bei einem hydraulischen Türschließer über dessen Hydraulik erreichen. Fehlt eine Hydraullk oder eine vergleichbare Einrichtung, so muß das Feststellen auf andere Weise vorgenommen werden. Dies gilt auch, wenn man eine gegebenenfalls vorhandene Hydraulik für einen bestimmten Öffnungswinkel nicht heranziehen will oder kann.The task of every door closer is to close the door again after the opening force ceases, for example when a person opening the door releases the latter. However, one is not fundamentally interested in closing the door, there are also applications in which the door is to remain at a certain opening angle. This locking of the door in an open rotational position can be achieved, for example, with a hydraulic door closer via its hydraulics. If a Hydraullk or comparable device is missing, the determination must be carried out in another way. This also applies if one does not want or cannot use any hydraulic system that may be available for a certain opening angle.

Aus der DE-OS 38 06 662 ist eine Feststellvorrichtung bekannt, bei der das Feststellen der Tür mit Hilfe eines Elektromagneten erfolgt.A locking device is known from DE-OS 38 06 662, in which the door is locked with the aid of an electromagnet.

Bei dieser bekannten Feststellvorrichtung ist an einem in einer Führungsschiene verschiebbar angeordneten ersten Schlitten ein zweiter Schlitten verschiebbar gelagert. Das Verstellen bzw. Einstellen das Feststellwinkels erfolgt durch Positionieren und Feststellen des ersten Schlittens, während das Feststellen der Tür einer geöffneten Drehlage das Zusammenwirken des zweiter Schlittens mit einem außerhalb der Bewegungsbahn des Schwenkglieds am ersten Schlitten angeordneten Elektromagneten erfordert. Die mit dem beweglichen Schwenkglied zusammenwirkende Lagerrolle wird beim Bewegen des Fensterflügels relativ zum zweiten Schlitten gegen eine Druckfeder verschoben. Wenn bei eingeschaltetem Elektromagneten die Tür unter Wirkung des Türschließers in Schließstellung geschwenkt wird, kann die Gleitrolle das Schwenkglied nicht passieren, und die Tür ist in einer geöffneten Drehlage festgestellt. Das Zudrücken der Tür von Hand oder das Abschalten des Elektromagneten hebt das Feststellen der Tür auf. Beim Öffnen der Tür wird das Passieren der Gleitrolle weder bei eingeschaltetem noch bei ausgeschaltetem Elektromagneten durch das Schwenkglied verhindert. Diese Feststellvorrichtung macht einerseits die Verwendung einer zusätzlichen Druckfeder notwendig, und andererseits ist bei dieser Konstruktion grundsätzlich die Verwendung eines Elektromagneten erforderlich.In this known locking device, a second carriage is slidably mounted on a first carriage which is arranged displaceably in a guide rail. The adjustment or adjustment of the locking angle is carried out by positioning and locking the first slide, while locking the door of an open rotational position requires the interaction of the second slide with an electromagnet arranged outside the movement path of the pivoting member on the first slide. The bearing roller cooperating with the movable pivot member is displaced relative to the second slide against a compression spring when the window sash is moved. If, with the electromagnet switched on, the door is pivoted into the closed position under the action of the door closer, the sliding roller cannot pass the pivot member and the door is locked in an open rotational position. Pushing the door shut by hand or switching off the electromagnet releases the locking of the door. When the door is opened, the swivel link does not prevent the roller from passing through when the electromagnet is switched on or off. This locking device on the one hand requires the use of an additional compression spring, and on the other hand the use of an electromagnet is fundamentally required in this construction.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Türschließer mit einer Feststellvorrichtung zu schaffen, die in ihrer Grundausführung rein mechanisch arbeitet, robust aufgebaut ist und ein sicheres Funktionieren gewährleistet.The invention is therefore based on the object of providing a door closer with a locking device which, in its basic design, operates purely mechanically, is of robust construction and ensures safe functioning.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß am Schiebeglied das eine Ende zumindest einer Belastungsfeder für das Schwenkglied anliegt, deren anderes Ende am Gehäuse od. dgl. der Vorrichtung abgestützt ist, und daß die Andrückrolle unverschiebbar am Schiebeglied gehalten ist, wobei das im sperrenden Sinne am Schwenkglied wirkende Drehmoment der Feststellvorrichtung mindestens durch die Belastungsfeder oder -federn des Schwenkglieds erzeugt ist.The object is achieved in that on the sliding link one end of at least one loading spring for the swivel member rests, the other end of which is supported on the housing or the like of the device, and that the pressure roller is held immovably on the sliding member, the locking device torque acting on the swivel member of the locking device at least by the loading spring or springs of the pivot member is generated.

Diese rein mechanische Feststellvorrichtung, die sich wie alle mechanischen Vorrichtungen durch besondere Robustheit und Funktionssicherheit auszeichnet, ist sehr einfach aufgebaut und, weil nur wenige Teile notwendig sind, auch preiswert zu fertigen. Die vorrichtung wird seitlich, beispielsweise an die Unterseite der Führungsschiene, so anmontiert, daß ihr federbelastetes Schwenkglied in der Arbeitssteilung in den Bewegungsbereich der Gleitrolle hineinragt. Beide müssen einander so zugeordnet sein, daß die Gleitrolle beim Öffnen der Tür gegen das Schwenkglied hin verschoben wird und im Zusammenwirken mit der ersten Aufgleitschräge das Schwenkglied so weit nach unten wegschwenkt, bis sie sich über das Schwenkglied hinweg weiterbewegen kann. Öffnet man die Tür über die für die Feststellung vorgesehene Schwenklage hinaus, so führt sie der Türschließer nach Wegfall der Öffnungskraft in Richtung der Schließlage zurück. Nunmehr steht aber aufgrund der Kraft der Belastungsfeder oder -federn das Schwenkglied wiederum im Verschiebebereich der rückkehrenden Führungsrolle. Sie trifft jedoch aufgrund ihrer nunmehr gegenläufigen Verschiebebewegung auf die zweite Aufgleitschräge auf. Die Schließkraft des Türschließers ist nicht in der Lage, im Zusammenwirken von Gleitrolle und zweiter Aufgleitschräge das Schwenkglied abermals in entsperrendem Sinne zu drehen.This purely mechanical locking device, which, like all mechanical devices, is characterized by particular robustness and functional reliability, has a very simple structure and, because only a few parts are necessary, can also be manufactured inexpensively. The device is mounted laterally, for example on the underside of the guide rail, in such a way that its spring-loaded pivoting member in the division of labor projects into the range of motion of the castor. Both must be assigned to each other in such a way that the slide roller is displaced towards the swivel member when the door is opened and, in cooperation with the first sliding slope, swings the swivel member downwards until it can continue to move over the swivel member. If the door is opened beyond the swivel position provided for the determination, the door closer leads it back towards the closed position after the opening force ceases. Now, however, due to the force of the loading spring or springs, the pivot member is again in the displacement area of the returning guide roller. However, due to its now counter-moving movement, it strikes the second slope. The closing force of the door closer is not able to turn the swivel link again in the unlocking sense in the interaction of the sliding roller and the second sliding slope.

Das Moment aus der oder den Belastungsfedern des Schwenkglieds ist nämlich größer als das in Gegenrichtung wirkende Moment aus der Schließkraft des Türschließers. Infolgedessen bleibt die Tür in der durch diese Feststellvorrichtung vorgegebenen Öffnungslage stehen. Sie kann aber ohne weiteres geschlossen werden, indem man den Türflügel durch eine einsprechende Kraft, beispielsweise von Hand, in Schließrichtung belastet. Eine solche von Hand aufgegebene Kraft ist zumindest in Verbindung mit der Schließkraft des Türschließers in der Lage, die "Sperrkraft" der Belastungsfeder oder -federn bzw. das hieraus resultierende Moment zu überwinden. Sobald die Gleitrolle od. dgl. wieder der ersten Aufgleitschräge zugeordnet ist, kann die Handkraft entfallen, weil nunmehr die Schließkraft des Türschließers zum vollständigen Schließen der Tür ausreicht.The moment from the loading spring or springs of the swivel member is namely greater than the moment acting in the opposite direction from the closing force of the door closer. As a result, the door remains in the opening position specified by this locking device. However, it can easily be closed by loading the door leaf in the closing direction by an opposing force, for example by hand. Such a force given up by hand is able, at least in connection with the closing force of the door closer, to overcome the "locking force" of the loading spring or springs or the moment resulting therefrom. As soon as the sliding roller or the like is again assigned to the first sliding slope, the manual force can be dispensed with because the closing force of the door closer is now sufficient to completely close the door.

Eine Weiterbildung der Erfindung sieht vor, daß das Schwenkglied als drehbar an einem Grundkörper, Gehäuse od. dgl. der Vorrichtung gelagerter Hebel ausgebildet ist, der mit zumindest einem Teil seiner Längskante die beiden Aufgleitschrägen bildet, wobei in der Arbeitsstellung des Schwenglieds die erste Aufgleitschräge mit der Längsachse der Führungsschiene einen größeren Winkel bildet als die zweite Aufgleitschräge und daß das Schwenkglied mit einem rückwärtigen Ansatz versehen und dadurch als zweiarmiger Hebel ausgebildet ist, wobei der rückwärtige Ansatz das als Raste ausgebildete eine Teil einer Arretierungsvorrichtung für die wirkungslose Steilung bildet, deren anderes Teil mit einer Rastaufnahme versehen ist, wobei ferner die Rastaufnahme in den Schwenkbereich der Raste bringbar ist. Dadurch kann beim Öffnen der Tür die Gleitrolle od. dgl. ohne besonderen Kraftaufwand leicht über die erste Aufgleitschräge hinwegbewegt werden, die man vorzugsweise auch länger ausbildet als die zweite, während dann die zweite aufgrund ihrer größeren Schräglage und auch der Krafteinleitung bezüglich der geometrischen Schwenkachse des Schwenkglieds in der Art eines verschwenkbaren Anschlags wirkt. In der Praxis wird es so sein, daß man die Tür zunächst etwas weiter öffnet, als die vorgesehene Feststellöffnungsweite und dann nach Freigabe die Tür die Gleitrolle nach mehr oder weniger kurzem Drehwinkel, in Schließrichtung gesehen, an der zweiten Aufgleitschräge auftrifft, wodurch dann die Schließbewegung beendet wird. Im "Normalbetrieb" ist diese Arretierungsvorrichtung unwirksam, d. h. die Tür wird ab einem gewissen Öffnungswinkel in der zugeordneten Öffnungsstellung festgehalten, wenn man sie freigibt. Es gibt aber auch Anwendungsfälle, wo man auf das Feststellen der Tür kurzzeitig oder für eine gewisse Zeit gerne verzichten möchte. Mit Hilfe dieser Arretierungsvorrichtung kann man nun die Feststellvorrichtung so lange außer Kraft setzen, wie dies erwünscht ist. Hierzu bedarf es lediglich der Überführung der Rastaufnahme in eine wirksame Stellung, in der sie das Drehen des Schwenkgliedes unterbindet. Dabei ist die Belastungsfeder der Vorrichtung verhältnismäßig stark gespannt, so daß sie nach dem Verbringen der Rastaufnahme aus dem Bewegungsbereich der Raste das Schwenkglied sofort in die wirksame Stellung überführt. Hieraus erkennt man auch, daß die Arretierungsvorrichtung durch die Belastungsfeder oder -federn sicher in der Sperrlage gehalten wird.A further development of the invention provides that the swivel member is designed as a lever which is rotatably mounted on a base body, housing or the like of the device and which forms the two sliding slopes with at least part of its longitudinal edge, the first sliding slope also being in the working position of the swing member The longitudinal axis of the guide rail forms a larger angle than the second slide-on slope and that the pivoting member is provided with a rear extension and is thus designed as a two-armed lever, the rear extension forming part of a locking device for ineffective pitching, the other part of which is designed as a detent is provided with a snap-in receptacle, wherein the snap-in receptacle can also be brought into the pivoting range of the catch. As a result, when the door is opened, the sliding roller or the like can be easily moved over the first sliding slope without any special effort are moved away, which is preferably also formed longer than the second, while the second then acts in the manner of a pivotable stop due to its greater inclined position and also the introduction of force with respect to the geometric pivot axis of the pivot member. In practice, it will be the case that the door is initially opened a little further than the intended opening, and then after the door is released, the sliding roller, after a more or less short angle of rotation, seen in the closing direction, hits the second sliding slope, which then causes the closing movement is ended. In "normal operation" this locking device is ineffective, ie the door is held in the assigned open position from a certain opening angle when it is released. But there are also applications where you would like to do without locking the door for a short time or for a certain time. With the help of this locking device, the locking device can now be overridden for as long as is desired. All that is required is to transfer the snap-in receptacle into an effective position in which it prevents the pivoting member from rotating. The loading spring of the device is relatively strongly tensioned so that it immediately transfers the swivel member into the active position after the latching receptacle has been moved from the range of movement of the latch. From this you can also see that the locking device is held securely in the locked position by the loading spring or springs.

Eine andere Ausbildung der Erfindung besteht darin, daß das andere Ende der bzw. jeder Belastungsfeder über eine Druckplatte am Gehäuse od. dgl. abgestützt ist und die Druckplatte verschieb- und feststellbar am Gehäuse od. dgl. gelagert ist, wobei die Druckplatte mittels einer am Gehäuse od. dgl. gelagerten Schraube verschiebbar ist. Auf diese Weide läßt sich eine Federspanneinrichtung gut unterbringen, wodurch diese Vorrichtung leicht an den jeweiligen Türschließer bzw. eine entsprechend schwere Tür anzupassen ist.Another embodiment of the invention is that the other end of the or each loading spring is supported by a pressure plate on the housing or the like, and the pressure plate is displaceable and lockable is mounted on the housing or the like, the pressure plate being displaceable by means of a screw mounted on the housing or the like. A spring tensioning device can be accommodated well in this pasture, making this device easy to adapt to the respective door closer or a correspondingly heavy door.

Die Andrückfläche des Schwenkglieds verläuft in Weiterbildung der Erfindung in dessen Arbeitsstellung derart geneigt zur Längsachse der Führungsschiene, daß sie beim Drehen des Schwenkglieds in eine wirkungslose Stellung das Schiebeglied gegen den Widerstand seiner Belastungsfeder bzw. -federn verschiebt. Der Winkel, den die Andrückfläche beispielsweise mit einer senkrecht zur Türebene und zur Längsachse der Führungsschiene verlaufenden Ebene einschließt, liegt beispielsweise in der Größenordnung von 10 bis 30°. In Abhängigkeit von diesem Winkel sowie dem Schwenkwinkel des Schwenkglieds ergibt sich eine mehr oder weniger große Verschiebebewegung des Schiebers gegenüber dem Vorrichtungsgehäuse od. dgl., und hieraus resultiert dann eine dementsprechende Federkaft für das Rückstellen dieses Systems. Im übrigen wird die Bewegung des Schwenkglieds in seine Arbeitsstellung zweckmäßigerweise durch einen Anschlag arretiert, sofern sich dies nicht auf andere Weise erreichen läßt, beispielsweise durch Ausnutzung der Führungsschiene oder Entspannen der Belastungsfeder in der Arbeitsstellung.The pressing surface of the pivot member extends in a further development of the invention in its working position so inclined to the longitudinal axis of the guide rail that it moves the sliding member against the resistance of its loading spring or springs when the pivot member is rotated into an ineffective position. The angle which the pressing surface forms, for example, with a plane running perpendicular to the door plane and to the longitudinal axis of the guide rail is, for example, in the order of 10 to 30 °. Depending on this angle and the swivel angle of the swivel member, there is a more or less large displacement movement of the slide relative to the device housing or the like, and this then results in a corresponding spring force for resetting this system. In addition, the movement of the pivoting member into its working position is expediently locked by a stop, unless this can be achieved in another way, for example by utilizing the guide rail or relaxing the loading spring in the working position.

In besonders vorteilhafter Weise befindet sich die Rastaufnahme an einem im Gehäuse od. dgl. quer zur Drehachse des Schwenkglieds verschiebbaren Rastglied, welches man insbesondere mit einer entsprechender Handhabe versieht, so daß man es leicht von der Arbeits-in die Freigabestellung und umgekehrt verschieben kann. Um einen Mißbrauch zu verhindern, kann man die Handhabe abnehmbar anbringen.In a particularly advantageous manner, the latching receptacle is located on a latching member which can be displaced transversely to the axis of rotation of the swivel member in the housing or the like and which is in particular provided with a corresponding handle, so that it can be easily removed from the working position can shift the release position and vice versa. To prevent misuse, the handle can be detachably attached.

Eine weitere bevorzugte Ausführungsform der Erfindung besteht darin, daß das Gehäuse od. dgl. der Vorrichtung längsverschiebbar an der Führungsschiene oder einem mit dieser verbundenden Zusatzprofil gelagert sowie mittels einer Festsetzvorrichtung in jeder Verschiebelage festsetzbar ist. Dies ermöglicht nicht nur das nachträgliche Anbringen der Festsetzvorrichtung an bereits vorhandenen Türen, sondern die Placierung quasi an beliebiger Stelle der Führungsschiene, so daß, zumindest in weiten Grenzen, die Tür bei jedem Öffnungswinkel arretiert werden kann. Im Falle eines Zusatzprofils kann man dies vorteilhafterweise mit der Führungsschiene kombinieren, wodurch sich der Montageaufwand verringert und eine besonders vorteilhafte optische Konstruktion entsteht. Hier ist vor allen Dingen die gewissermaßen verdeckte Unterbringung der Feststellvorrichtung am festen Rahmen zu erwähnen.A further preferred embodiment of the invention consists in that the housing or the like of the device is mounted in a longitudinally displaceable manner on the guide rail or an additional profile connected to it, and can be fixed in any displacement position by means of a fixing device. This not only enables the fixing device to be retrofitted to existing doors, but also allows it to be placed virtually anywhere on the guide rail, so that the door can be locked at any opening angle, at least within wide limits. In the case of an additional profile, this can advantageously be combined with the guide rail, as a result of which the assembly effort is reduced and a particularly advantageous optical construction is created. Above all, the so-called hidden placement of the locking device on the fixed frame should be mentioned.

Eine weitere sehr vorteilhafte Variante der Erfindung ergibt sich aus Anspruch 9. Sie ermöglicht die Verwendung des Türschließers mit dieser Feststellvorrichtung beispielsweise an einer Brandschutztür, und zwar in Verbindung mit einen Brandmelder od. dgl. Bezogen auf ein und denselben Türschließer muß bei dieser Vorrichtung die Kraft der Belastungsfeder oder -federn geringer sein als bei den Ausführungen ohne Elektromagnet, weil sich dessen Haltekraft zur Kraft der Belastungsfedern addiert. Die Kraft der Belastungsfeder sollte, bezogen auf die vorstehend beschriebene Variante, etwa um die Magnetkraft verringert sein. Wenn im Brandfalle der Brandmelder od. dgl. den Strom zum als Haltemagnet ausgebildeten Elektromagneten unterbricht, so verringert sich dadurch das am Schwenkglied angreifende, es in eine Arbeitsstellung überführende Drehmoment, und es kann sich nunmehr das in Gegenrichtung wirkende nunmehr größere Moment aus der Kraft des Türschließers auswirken. Infolgedessen wird das Schwenkglied von der Führungsrolle niedergedrückt und die Tür geschlossen. Die Kraft der Belastungsfeder ist trotz ihrer geringeren Größe aber auch in der Lage, bei geschlossener Tür alle ausgelenkten Teile der Feststellvorrichtung wieder in ihre Arbeitsstellung zu überführen. Sobald die Kraft des Elektromagneten wieder vorhanden ist, kann die geöffnete Tür mit dieser Feststellvorrichtung wieder arretiert werden.Another very advantageous variant of the invention results from claim 9. It enables the use of the door closer with this locking device, for example on a fire door, in conjunction with a fire detector or the like. Relating to one and the same door closer, the force must be in this device the load spring or springs may be less than the versions without an electromagnet, because its holding force is added to the force of the load springs. The force of the load spring should be reduced by about the magnetic force, based on the variant described above. If, in the event of a fire, the fire detector or the like, the current to the electromagnet designed as a holding magnet interrupts, this reduces the torque acting on the swivel member, which converts it into a working position, and the now greater moment acting in the opposite direction can now have an effect from the force of the door closer. As a result, the pivot member is depressed by the guide roller and the door is closed. Despite its smaller size, the force of the load spring is also able to move all of the deflected parts of the locking device back into their working position when the door is closed. As soon as the power of the electromagnet is available again, the opened door can be locked again with this locking device.

Die Tür 1 ist drehbar an einem festen Rahmen 2 gelagert. Sie besitzt zu diesem Zwecke wenigstens zwei übereinander angeordnete Drehlager 3, von denen das obere in Fig. 1 zu sehen ist. Am oberen Ende der Tür ist ein Türschließer 4 befestigt, der infolgedessen als sogenannter Obentürschließer ausgebildet ist. Am festen Rahmen befindet sich die Führungsschiene 5, in welche das am freien Ende eines mit dem Türschließer 4 gekuppelten bzw. drehbar daran gelagerten Gleitarm 6 angebrachte Gleitelement, beispielsweise ein Gleitschuh, eine Gleitrolle 7 od. dgl. senkrecht zur Bildebene der Fig. 1 verschiebbar gelagert ist. Das türschliesserseitige Ende des Gleitarms 6 ist drehfest mit der Antriebswelle des Türschließers gekuppelt. Öffnet man die Tür in Pfeilrichtung 8, so bewirkt dies einerseits ein Drehen des Gleitarms durch die Antriebswelle und andererseits ein Drehen sowie Längsverschieben des Gleitelements bzw. der Gleitrolle 7 in der Führungsschiene 5 in Pfeilrichtung 9. Die Wirkungsweise des hydraulischen Obentürschließers als solche ist bereits bekannt. Durch das Drehen der Antreibswelle wird über einen entsprechenden Umsetzungsmechanismus ein Kolben im Türschließer verschoben, der ein in letzteren eingefülltes Medium von einem vor dem Kolben befindlichen Zylinderraum in einen dahinter angeordneten verdrängt. Dabei wird eine Rückstellfeder des Türschließers gespannt, welche den Kolben nach Loslassen der Tür wieder in die Ausgangslage zurückdreht. Beim Zurückdrehen und der hierdurch verursachten Rückströmung fließt das Hydraulikmedium über einen anderen Strömungsweg als beim Öffnen der Tür wieder zurück.The door 1 is rotatably mounted on a fixed frame 2. For this purpose, it has at least two rotary bearings 3 arranged one above the other, the upper one of which can be seen in FIG. 1. At the upper end of the door, a door closer 4 is attached, which is consequently designed as a so-called overhead door closer. On the fixed frame there is the guide rail 5, in which the one at the free end of a coupled to the door closer 4 or rotatably mounted thereon Sliding arm 6 attached sliding element, for example a sliding shoe, a sliding roller 7 or the like. Is slidably mounted perpendicular to the image plane of FIG. 1. The end of the sliding arm 6 on the door closer side is coupled in a rotationally fixed manner to the drive shaft of the door closer. If the door is opened in the direction of the arrow 8, this causes on the one hand a rotation of the sliding arm by the drive shaft and on the other hand a rotation and longitudinal displacement of the sliding element or the sliding roller 7 in the guide rail 5 in the direction of the arrow 9. The mode of operation of the hydraulic overhead door closer as such is already known . By rotating the drive shaft, a piston is displaced in the door closer via a corresponding conversion mechanism, which displaces a medium filled in the latter from a cylinder space located in front of the piston into a cylinder located behind it. A return spring of the door closer is tensioned, which turns the piston back to the starting position after releasing the door. When turning back and the backflow caused thereby, the hydraulic medium flows back via a different flow path than when the door is opened.

Soll die Tür nicht grundsätzlich geschlossen, sondern in einer bestimmten Öffnungsstellung festgehalten werden, so benötigt man eine Feststellvorrichtung, welche die geöffnete Tür trotz des von Türschließer auf sie ausgeübten schließ-Drehmoments in der betreffenden Drehöffnungsstellung festhält. Zwei Ausführungsbeispiele einer solchen Feststellvorrichtung sind in der Zeichnung dargestellt und werden nachstehend detailliert beschrieben.If the door is not to be closed in principle, but is to be held in a certain opening position, a locking device is required which holds the opened door in the relevant opening position in spite of the closing torque exerted on it by the door closer. Two embodiments of such a locking device are shown in the drawing and are described in detail below.

Ein wichtiges Element der Feststellvorrichtung ist ein Schwenkglied 10, welches mittels wenigstens einer, bei den Ausführungsbeispielen aber mittels zweier Federn 11 in Pfeilrichtung 12 belastet ist. Die Drehachse des Schwenkglieds 10 ist mit 13 bezeichnet. Aus Fig. 3 erkennt man, daß das Schwenkglied 10 in seiner Arbeitsstellung in den Verschiebebereich der Gleitrolle 7 hineinragt. Hierbei ist allerdings die Stellung der Gleitrolle gezeichnet, die sie bei festgestellter Tür einnimmt. Bei geschlossener Tür steht sie wesentlich weiter rechts, d. h., sie wird beim Öffnen der Tür in Pfeilrichtung 14 entlang ihrer Gleitbahn 15 verschoben.An important element of the locking device is a swivel member 10, which by means of at least one, in the exemplary embodiments but is loaded by two springs 11 in the direction of arrow 12. The axis of rotation of the pivot member 10 is designated 13. From Fig. 3 it can be seen that the pivot member 10 protrudes into the displacement area of the roller 7 in its working position. Here, however, the position of the roller is drawn, which it assumes when the door is locked. When the door is closed, it is much further to the right, ie it is moved along its slideway 15 in the direction of arrow 14 when the door is opened.

Das Schwenkglied 10 besitzt zwei gegenläufig abfallende, in Bezug auf die Bewegungsrichtung 14 hintereinanderliegende Aufgleitschrägen 16 und 17. Die erste Aufgleitschräge 16 istlänger als die zweite Aufgleitschräge 17. Mit der Längsachse der Führungsschiene 5 schließt die Aufgleitschräge 16 einen Winkel 56 und die Aufgleitschräge 17 einen demgegenüber kleineren Winkel 57 ein. Ausgehend von der geschlossenen Tür 1 erreicht die Gleitrolle 7 zunächst die etwas flacher verlaufende erste Aufgleitschräge 16. Eine genügend große Handkraft beim Öffnen der Tür bewirkt ein Drehen des Schwenkglieds 10 entgegen dem Pfeil 12 bei gleichzeitigem Spannen bzw. stärkeren Spannen der Belastungsfeder oder - federn 11. Der Einfachheit halber wird nachstehend lediglich noch von "Belastungsfedern" gesprochen, ohne daß dies einschränkend gemeint ist.The pivot member 10 has two oppositely sloping sliding slopes 16 and 17 with respect to the direction of movement 14. The first sliding slope 16 is longer than the second sliding slope 17. With the longitudinal axis of the guide rail 5, the sliding slope 16 closes an angle 56 and the sliding slope 17 in contrast smaller angle 57 a. Starting from the closed door 1, the sliding roller 7 first reaches the somewhat flatter first sliding slope 16. A sufficiently large hand force when the door is opened causes the pivoting member 10 to rotate counter to the arrow 12 with simultaneous tensioning or stronger tensioning of the loading spring or springs 11 For the sake of simplicity, only "load springs" are referred to below, without this being intended to be restrictive.

Die beiden Aufgleitschrägen 16 und 17 gehen bei den Ausführungsbeispielen unmittelbar ineinander über. Sobald die Gleitrolle 7 die höchste Kante 18 des Schwenkgliedes 10 überlaufen hat, kann dieses aufgrund der Kraft der Federn 11 wieder in die aus Fig. 3 ersichtliche Arbeitsstellung gehen. Die Schwenkendbewegung wird mittels eines Anschlage, z.B. eines kleinen Bolzens 19 od. dgl. Element gesichert, der in ein entsprechendes Langloch, einen Durchbruch od. dgl. eines Gehäuses 20 der Feststellvorrichtung eingreift. Statt dessen kann man auch eine kleine Prägung anbringen, die mit einer Gegenprägung zusammenwirkt.The two sliding slopes 16 and 17 merge directly into one another in the exemplary embodiments. As soon as the sliding roller 7 has passed the highest edge 18 of the swivel member 10, this can go back into the working position shown in FIG. 3 due to the force of the springs 11. The pivoting end movement is secured by means of a stop, for example a small pin 19 or the like element, which engages in a corresponding slot, an opening or the like. A housing 20 of the locking device. Instead, you can also apply a small embossing that interacts with a counter-embossing.

Das Schwenkglied 10 ist bei beiden Ausführungsbeispielen ein doppelarmiger Hebel. Der in der Zeichnung linke Hebelarm bildet mit seiner nach oben weisenden Längskante die beiden Aufgleitschrägen 16 und 17. Daran schließt sich ein nach unten weisender hakenartiger Ansatz 21 an. Bei wirkungsloser Feststellvorrichtung umgreift der Haken eine Andrückrolle 22 (Fig. 8). In der aus Fig. 3 ersichtlichen Arbeitsstellung des Schwenkglieds 10 verläuft dessen am hakenartigen Ansatz 21 angebrachte Andrückfläche 23 unter einem spitzen Winkel 24 zu einer gedachten Vertikalebene 25 senkrecht zur Türebene und zur Längsachse der Führungsschiene 5. Weil die Andrükkrolle 22 an einem im Sine des Doppelpfeils 26 verschiebbar am Gehäuse der Vorrichtung gelagerten Schiebeglied 27 befestigt ist, bewirkt die Schrägstellung der Andrückfläche 23 im Zusammenwirken mit der Andrückrolle 22 bei einem Drehen des Schwenkgliedes 10 entgegen dem Pfeil 12 eine seitliche Verlagerung des Schiebeglieds 27 in Pfeilrichtung 28 bei gleichzeitigem Spannen der Belastungsfedern 11. Zu einem solchen Verschieben kommt es, wenn man mit der Gleitrolle 7 in Pfeilrichtung 28 gegen die zweite Aufgleitfläche 17 mit genügend großer Kraft drückt. Zwar wird vom Türschließer bzw. dessen Schließfeder eine derartige Kraft über die Gleitrolle 7 auf das Schwenkglied 10 aufgegeben, jedoch bewirken die beiden Belastungsfedern 11 über das Schiebeglied 27 und die Andrückrolle 22 ein gegenläufiges Drehmoment, also ein Drehmoment im Uhrzeigersinne, welches größer ist und infolgedessen dem in Gegenuhrzeigersinne wirkenden Drehmoment des Türschließers erfolgreich entgegenwirkt. Erst wenn man durch Drücken gegen die Tür an der zweiten Aufgleitschräge 17 eine noch stärkere Kraft aufbringt, überwiegt das Drehmoment im Gegenuhrzeigersinne, und dann vermag die Gleitrolle 7 das Schwenkglied 10 in die aus Fig. 8 ersichtliche Freigabestellung zu drehen. Man ersieht beispielsweise auf Fig. 3, daß die beiden Aufgleitschrägen 16 und 17 einen etwa 90°-Winkel miteinander einschließen. Aus Fig. 8 ergibt sich, daß die erste Aufgleitschräge 16 beim Überfahren der höchsten Kante 18 etwa parallel zur Längsachse der Führungsschiene 5 verläuft bzw. damit einen ganz spitzen Winkel einschließt.The pivot member 10 is a double-armed lever in both embodiments. The lever arm on the left in the drawing, with its upward-pointing longitudinal edge, forms the two sliding bevels 16 and 17. This is followed by a downward-facing hook-like extension 21. When the locking device is ineffective, the hook engages around a pressure roller 22 (FIG. 8). In the working position of the pivoting member 10 shown in FIG. 3, its pressing surface 23 attached to the hook-like extension 21 extends at an acute angle 24 to an imaginary vertical plane 25 perpendicular to the door plane and to the longitudinal axis of the guide rail 5. Because the pressing roller 22 on one in the sense of the double arrow 26 slidably mounted on the housing of the device sliding member 27, the inclined position of the pressing surface 23 in cooperation with the pressure roller 22 causes a lateral displacement of the sliding member 27 in the direction of arrow 28 while rotating the pivoting member 10 against the arrow 12 while simultaneously tensioning the load springs 11. Such a shift occurs when the slide roller 7 is pressed with sufficient force in the direction of arrow 28 against the second sliding surface 17. Although such a force is exerted by the door closer or its closing spring via the sliding roller 7 onto the swivel member 10, the two loading springs 11 cause an opposing torque, i.e. a torque in the clockwise direction, via the sliding member 27 and the pressure roller 22 is larger and consequently successfully counteracts the counterclockwise torque of the door closer. Only when an even stronger force is exerted by pressing against the door on the second sliding slope 17 does the torque prevail in the counterclockwise direction, and then the sliding roller 7 is able to turn the swivel member 10 into the release position shown in FIG. 8. It can be seen, for example, in FIG. 3 that the two sliding slopes 16 and 17 enclose an approximately 90 ° angle with one another. From Fig. 8 it follows that the first sliding bevel 16 runs approximately parallel to the longitudinal axis of the guide rail 5 when passing over the highest edge 18 or thus includes a very acute angle.

Der zweite Hebelarm des Schwenkgliedes 10 bildet einen rückwärtigen Ansatz 29. Er, oder genauer gesagt sein freies Ende, bildet eine Raste 30 einer Arretierungsvorrichtung 31. Das zweite Teil dieser Arretierungsvorrichtung bildet eine Rastaufnahme 32. Diese befindet sich an einem Verrastglied 33, welches im Sinne des Doppelpfeils 26 längsverschiebbar am Vorrichtungsgehäuse 20 gelagert ist. Die Längsführung ist in Fig. 3 mit 34 bezeichnet. Dort nimmt das Rastglied 33 seine wirkungslose Stellung ein, während es sich in Fig. 8 in seiner wirksamen Stellung befindet. Dabei greift dann die Raste 30 in den kerbenartigen rechten Teil der Rastaufnahme 32 ein. Nunmehr kann sich die Kraft der Federn 11 nicht auswirken, und infolgedessen ist die Feststellvorrichtung außer Kraft gesetzt.The second lever arm of the pivot member 10 forms a rear extension 29. It, or more precisely its free end, forms a catch 30 of a locking device 31. The second part of this locking device forms a catch receptacle 32. This is located on a catch member 33, which in the sense of the double arrow 26 is mounted longitudinally displaceably on the device housing 20. The longitudinal guide is designated by 34 in FIG. 3. There, the locking member 33 assumes its ineffective position, while it is in its active position in FIG. 8. The catch 30 then engages in the notch-like right part of the catch receptacle 32. The force of the springs 11 can now have no effect, and as a result the locking device is deactivated.

Ein abnehmbarer Griff 35 ist mit Hilfe seines zapfenartigen Ansatzes drehfest mit dem Rastglied 33 gekuppelt. Eine Schraube sichert diese Verbindung. Nachdem sich an beiden stirnseitigen Enden des Rastglieds 33 je eine Aufnahme 36 und eine Gewindebohrung befinden, kann man den Griff wahlweise an einem der beiden Enden des Rastglieds 33 anmontieren. Der Türschließer ist somit sowohl für DIN-rechte als auch DIN-linke Türen verwendbar.A removable handle 35 is coupled in a rotationally fixed manner to the latching member 33 with the aid of its pin-like projection. A screw secures this connection. After at both ends of the Detent member 33 each have a receptacle 36 and a threaded bore, the handle can optionally be mounted on one of the two ends of the detent member 33. The door closer can therefore be used for both DIN right and DIN left doors.

Wie man besonders gut aus Fig. 4 ersieht, besteht das Gehäuse 20 der Vorrichtung vorzugsweise aus zwei plattenförmigen Körpern 37 und 38, die über Distanzelemente 39 und 40 zusammengehalten sind. Ersteres ist ein eingenieteter Distanzbolzen (Fig. 4), während das Distanzelement 40 als eingenietete Buchse ausgebildet ist, die ein Innengewinde 41 trägt. Die Belastungsfedern 11 stecken in entsprechenden Sackbohrungen des Schiebeglieds 27 und stützen sich dadurch mit ihrem in der Zeichnung jeweils linken Ende am Schiebeglied ab. Ihr jeweils rechtes Ende liegt an einer Druckplatte 42 an, die in gleichem Sinne wie das Schiebeglied 27 längsverschiebbar am Gehäuse 20 der Vorrichtung gelagert ist. An der rückwärtigen Fläche der Druckplatte 42 greift das freie Ende einer Einstellschraube 43 an, die in einem Quersteg 44 od. dgl. des Gehäuses 20 verschraubbar ist. Mit Hilfe der Schraube 43 kann man somit die Spannung der Federn 11 einstellen.As can be seen particularly well from FIG. 4, the housing 20 of the device preferably consists of two plate-shaped bodies 37 and 38, which are held together via spacer elements 39 and 40. The former is a riveted-in spacer bolt (FIG. 4), while the spacer element 40 is designed as a riveted-in bushing which has an internal thread 41. The loading springs 11 are inserted in corresponding blind bores of the sliding member 27 and are thereby supported on the sliding member by their left end in the drawing. Their right end lies against a pressure plate 42, which is mounted in the same sense as the sliding member 27 to be longitudinally displaceable on the housing 20 of the device. The free end of an adjusting screw 43 engages on the rear surface of the pressure plate 42 and can be screwed into a crosspiece 44 or the like of the housing 20. With the help of the screw 43, the tension of the springs 11 can thus be adjusted.

Die Führungsschiene 5 ist gemäß Fig. 10 als im Querschnitt C-förmige Schiene ausgebildet und einstückig mit einem Zusatzprofil 45 gefertigt. In letzterem ist die erfindungsgemäße Feststellvorrichtung verschieb- und arretierbar gelagert. Man kann sie somit quasi jeder beliebigen Stelle des oberen Festrahmenquerholms zuordnen. Wenn sie in die richtige Position gebracht wurde, so wird diese mit Hilfe einer Festsetzvorrichtung 46 gesichert (Fig. 9). Diese besteht im wesentlichen aus einer Klemmplatte 47 sowie einer Klemmschraube 48. Letztere durchsetzt einen Längsschlitz 49 der Profilschiene bzw. des Zusatzprofils 45. Es ist leicht einzusahen, daß man durch Festziehen der Schraube 48 die Klemmplatte 47 außen an dem Profilschenkel 50 anpressen und dadurch die erfindungsgemäße Feststellvorrichtung verschiebefest sichern kann. Bei dieser Gelegenheit wird noch darauf hingewiesen, daß die durch die beiden Aufgleitschrägen 16 und 17 gebildete Ecke des Schwenkglieds 10 einen Profilschlitz 51 von unten nach oben durchsetzt.According to FIG. 10, the guide rail 5 is designed as a cross-sectionally C-shaped rail and is made in one piece with an additional profile 45. In the latter, the locking device according to the invention is mounted displaceably and lockable. You can assign them to virtually any position on the upper fixed cross member. If it has been brought into the correct position, it is secured with the aid of a fixing device 46 (FIG. 9). This essentially consists of a clamping plate 47 and a clamping screw 48. The latter passes through a longitudinal slot 49 of the profile rail or the additional profile 45. It is easy to see that the clamping plate 47 can be pressed on the outside of the profile leg 50 by tightening the screw 48 and thereby the locking device according to the invention can be secured against displacement. On this occasion it is pointed out that the corner of the swivel member 10 formed by the two sliding bevels 16 and 17 passes through a profile slot 51 from bottom to top.

Der plattenförmige Körper 37 des Vorrichtungsgehäuses 20 ist mit einem Durchbruch 52 versehen. In diesen kann man gemäß Fig. 11 einen Elektromagneten 53 einsetzen. Wenn man das Schiebeglied 27 aus ferromagnetischem Material herstellt oder an seiner Außenseite eine entsprechende Platte anbringt, so zieht der erregte Elektromagnet 53 das Schiebeglied 27 in die aus Fig. 11 ersichtliche Stellung und hält es darin fest. Unterstützt wird diese Bewegung bei der zweiten Ausführungsform der Erfindung durch die Belastungsfedern 11. Diese sind allerdings schwächer oder schwächer eingestellt als beim ersten Ausführungsbeispeil, weil beide Kräfte zusammen, nämlich die Federkraft und die Magnetkraft, etwa gleich groß sein sollen wie die Federkraft der Variante ohne Elektromagnet. Dies gilt für ein und dieselbe oder zumindest ähnliche Schließkraft des Türschließers 4. Um den Elektromagneten and elektrische Netz anschließen zu können, ist an der Vorrichtung bzw. an deren Gehäuse 20 noch ein Stromabnehmer 54 befestigt, der mit dem Elektromagneten 53 verbunden oder zumindest verbindbar ist. Er wirkt mit Leiterbahnen 55 zusammen, die an einem Montageprofil 58 vorgesehen sind. Mit Hilfe des letzteren wird die Führungsschiene 5 direkt oder indirekt am festen Rahmen anmontiert.The plate-shaped body 37 of the device housing 20 is provided with an opening 52. 11, an electromagnet 53 can be used in these. If the sliding member 27 is made of ferromagnetic material or a corresponding plate is attached to the outside, the excited electromagnet 53 pulls the sliding member 27 into the position shown in FIG. 11 and holds it there. This movement is supported in the second embodiment of the invention by the loading springs 11. However, these are set weaker or weaker than in the first embodiment, because both forces together, namely the spring force and the magnetic force, should be approximately the same as the spring force of the variant without Electromagnet. This applies to the same or at least similar closing force of the door closer 4. In order to be able to connect the electromagnet to the electrical network, a current collector 54 is also attached to the device or to its housing 20, which is connected or at least connectable to the electromagnet 53 . It interacts with conductor tracks 55, which are provided on an assembly profile 58. With the help of the latter, the guide rail 5 is mounted directly or indirectly on the fixed frame.

Bei erregtem Magneten 53 überwiegen die elektromagnetische Haltekraft und die Kraft der Federn 11 bzw. das hieraus resultierende Drehmoment in Pfeilrichtung 12 genenüber der Schließkraft des Türschließers 4 bzw. dem hieraus resultierenden, im Gegenuhrzeigersinne am Schwenkglied 10 wirkenden Drehmoment. Wenn der Strom zum Elektromagneten 53 beispielsweise mit Hilfe eines Brand- oder Rauchmelders unterbrochen wird, so entfällt die Haltekraft des Elektromagneten 53, und dann ist das Drehmoment aus den Federn 11 kleiner als das aus der Schließkraft des Türschließers resultierende Gegen-Drehmoment, weswegen der Türschließer nunmehr in der Lage ist, über die Gleitrolle 7 das Schwenkglied 10 entgegen dem Pfeil 12 niederzudrücken und die Tür zu schließen.When the magnet 53 is energized, the electromagnetic holding force and the force of the springs 11 or the torque resulting therefrom in the direction of arrow 12 outweigh the closing force of the door closer 4 or the resulting torque acting counterclockwise on the pivot member 10. If the current to the electromagnet 53 is interrupted, for example with the aid of a fire or smoke detector, the holding force of the electromagnet 53 is eliminated, and then the torque from the springs 11 is smaller than the counter-torque resulting from the closing force of the door closer, which is why the door closer is now able to press the swivel member 10 against the arrow 12 and close the door via the sliding roller 7.
