If a sufficiently large force acting against the arrow 18 acts on the sliding element 7, this again results in the locking element 15 being displaced in the direction of the arrow 20. As soon as the sliding element has passed over the hump 23 and is completely outside the displacement range of the locking element, the latter can return to the starting position. This release force is due to a manual closing movement of the door. After uncoupling the door can be released so that it is automatically closed with the help of the door closer.

Abstract

So that an opened door (1) can be fixed in a selectable predetermined opening position, in a door closer (4) designed as a top door closer and having a setting-out arm (6) guided in a sliding rail (5) a stop device (13) is mounted on the sliding rail (5). It has a spring-loaded detent element (15) which, in the intended opening position of the door, interlocks with a sliding element (7) attached to the free end of the setting-out arm (6). In particular, the detent element (15) projects into the path of movement of the sliding element (7) which moves along the sliding rail when the door is being opened. Because of slopes (19 and 22), both engagement and disengagement take place relatively easily, and disengagement can be obtained by means of a vigorous closing movement of the door. Instead, the detent element (15) can also be retracted by auxiliary force or by hand. To make assembly easier, the sliding rail (5) is mounted on the fixed frame (2) of the door (1) not directly, but indirectly via an assembly rail (41) previously screwed to the fixed frame. The connection is secured by means of screws (47). <IMAGE>

Description

Die Erfindung bezieht sich auf einen Türschließer, dessen Aus­stellarm einenends drehfest mit der Türschließer-Antriebswelle verbunden ist und andernends ein in einer an einem festen Rahmen od. dgl. der Tür angebrachten Gleitschiene zumindest verschieb­bares und vorzugsweise auch feststellbares Gleitelement trägt. Es handelt sich hierbei um einen sogenannten Obentürschließer mit einem Parallelarmgestänge, der an der Tür befestigt ist. Bei die­sem Türschließer wird der Ausstellarm in einer Gleitschiene am festen Rahmen geführt, wobei sein Gleitelement aufgrund der Ver­schwenkung des Ausstellarms beim Öffnen und Schließen der Tür in der Gleitschiene verschoben und gedreht wird. Der Ausstellarm steht dabei unter einer Vorspannung, die ihn vom festen Rahmen wegdrücken will. Diese Vorspannung kommt von einer Feder, welche, wie gesagt, den bei geschlossener Tür etwa parallel zu deren Ebene angeordneten Ausstellarm in Richtung seiner Schrägstellung belastet. Dies erschwert die Montage des Türschließers, insbeson­dere des Ausstellarms, in der Gleitschiene, weil letzterer mit seinem freien Ende bzw. seinem Gleitelement in die Gleitschiene eingeschoben werden muß.The invention relates to a door closer, the opening arm is connected at one end in a rotationally fixed manner to the door closer drive shaft and at the other end carries a sliding element which is at least displaceable and preferably also lockable in a slide rail attached to a fixed frame or the like. It is a so-called overhead door closer with a parallel arm linkage that is attached to the door. With this door closer, the opening arm is guided in a slide rail on the fixed frame, its sliding element being opened due to the pivoting of the opening arm when the door is opened and closed the slide rail is moved and rotated. The extension arm is under a pretension that wants to push it away from the fixed frame. This pretension comes from a spring which, as said, loads the opening arm which is arranged approximately parallel to its plane in the direction of its inclined position when the door is closed. This complicates the assembly of the door closer, in particular the opening arm, in the slide rail, because the latter must be inserted into the slide rail with its free end or its slide element.

Es liegt daher die Aufgabe vor, den eingangs beschriebenen Tür­schließer so weiterzubilden, daß seine Montage einfacher und da­mit rascher durchzuführen ist. Zur Lösung dieser Aufgabe wird er­findungsgemäß vorgeschlagen, daß der Türschließer gemäß dem Ober­begriff des Anspruchs 1 dadurch gekennzeichnet ist, daß die Gleitschiene mit einer mit dem festen Rahmen od. dgl. verbind­baren Montageschiene verbindbar ist.It is therefore the task of developing the door closer described at the outset in such a way that its assembly is easier and therefore quicker to carry out. To achieve this object, it is proposed according to the invention that the door closer according to the preamble of claim 1 is characterized in that the slide rail can be connected to a mounting rail which can be connected to the fixed frame or the like.

Am festen Rahmen od. dgl., insbesondere an dessen oberem Quer­holm, befestigt man zunächst die Montageschiene. Weil diese zu­mindest vor der Montage von der Gleitschiene getrennt ist, kann sich die Kraft der am Ausstellarm angreifenden Belastungsfeder beim Anschlagen der Montageschiene nicht auswirken. Wenn diese montiert ist, verbindet man mit ihr die Gleitschiene, an welcher sich bereits der Türschließer befindet. Während die Gleitschiene an den festen Rahmen üblicherweise angeschraubt wird, was ver­ hältnismäßig viel Zeit und genaues Arbeiten erfordert sowie durch die Federkraft des Ausstellarms zusätzlich erschwert ist, kann man bei diesem Türschließer die Gleitschiene mit der Montage­schiene durch Aufstecken, Aufschieben oder in anderer bekannter Schnellverbindungsart verhältnismäßig rasch kuppeln und an­schließend, soweit erforderlich, die Verbindung noch sichern. Dies geht wesentlich rascher vonstatten als das Anschrauben der Gleitschiene beim Stand der Technik bzw. der Montageschiene die­ses Türschließers. Infolgedessen wirkt sich die Kraft der Feder bei Verwendung einer Montageschiene kaum nachteilig aus, so daß dieser Türschließer insgesamt einfacher und letztendlich wegen der entfallenden Behinderung durch die Feder auch rascher mon­tiert werden kann.On the fixed frame or the like, in particular on its upper cross member, the mounting rail is first attached. Because this is separated from the slide rail at least prior to assembly, the force of the load spring acting on the extension arm cannot have an effect when the assembly rail is struck. When this is installed, the slide rail is connected to it, on which the door closer is already located. While the slide rail is usually screwed to the fixed frame, which ver requires a relatively large amount of time and precise work, and is also made more difficult by the spring force of the extension arm, with this door closer you can couple the slide rail with the mounting rail relatively quickly by plugging it on, sliding it on or in another known type of quick connection and then, if necessary, securing the connection. This is done much faster than screwing the slide rail in the prior art or the mounting rail of this door closer. As a result, the force of the spring hardly has a disadvantageous effect when a mounting rail is used, so that this door closer can be assembled more easily overall and, ultimately, because the spring is not obstructed, it can also be installed more quickly.

Bei einer bevorzugten Ausführungsform der Erfindung sind die Gleitschiene und die Montageschiene formschlüssig gekuppelt. Man kann sie also relativ rasch zusammenfügen.In a preferred embodiment of the invention, the slide rail and the mounting rail are coupled in a form-fitting manner. So you can put them together relatively quickly.

Eine Weiterbildung der Erfindung sieht vor, daß die Gleitschiene auf die Montageschiene von oben her aufsetzbar ist, wobei eine nach unten weisende Leiste der Gleitschiene eine in Gegenrichtung weisende andere Leiste der Montageschiene hintergreift. Sobald man die Gleitschiene mit dem Türschließer auf die Montageschiene von oben her aufgesteckt hat, ist die Montage zumindest weitge­hend abgeschlossen. Sofern man auf eine verrastende oder ähnliche automatische Verbindung verzichtet, muß man die Gleitschiene ge­ genüber der Montageschiene lediglich noch in Ausheberichtung sichern.A further development of the invention provides that the slide rail can be placed on the mounting rail from above, with a downward-facing strip of the slide rail engaging behind another strip of the mounting rail pointing in the opposite direction. As soon as you have slid the slide rail with the door closer onto the mounting rail from above, the assembly is at least largely completed. If you do without a latching or similar automatic connection, you have to ge the slide rail only secure in the lifting direction compared to the mounting rail.

Weitere vorteilhafte Ausgestaltungen beider erfindungsgemäßen Ausbildungen des Türschließers ergeben sich aus den Unteransprü­chen sowie der nachstehenden Zeichnungsbeschreibung.Further advantageous embodiments of both designs of the door closer according to the invention result from the subclaims and the description of the drawing below.

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 Gleitschiene 5, in welche das am freien Ende eines mit dem Türschließer 4 gekuppelten Ausstellarms 6 angebrachte Gleitelement 7 senkrecht zur Bildebene der Fig. 3 verschiebbar gelagert ist. Das türschließerseitige Ende des Aus­stellarms 6 ist drehfest mit der Antriebswelle 12 des Tür­schließers gekuppelt. Öffnet man die Tür in Pfeilrichtung 8, so bewirkt dies einerseits ein Drehen des Ausstellarms durch die An­triebswelle und andererseits ein Drehen sowie Längsverschieben des Gleitelements 7 in der Gleitschiene 5 in Pfeilrichtung 9. Die Wirkungsweise des hydraulischen Obentürschließers als solche ist bereits bekannt. Das Drehen der Antriebswelle bewirkt über einen entsprechenden Umsetzungsmechanismus das Verschieben eines Kol­bens im Türschließer, der ein in letzteren eingefülltes Medium von einem vor dem Kolben befindlichen Zylinderraum in einen da­ hinter 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, vor al­len Dingen aber muß es beim Schließen der Tür eine Drosselein­richtung durchströmen, wodurch das Schließen langsamer vonstatten geht als das normale Türöffnen.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 slide rail 5, in which the slide element 7, which is attached to the free end of an extension arm 6 coupled to the door closer 4, is slidably mounted perpendicular to the image plane of FIG. 3. The end of the opening arm 6 on the door closer side is coupled in a rotationally fixed manner to the drive shaft 12 of the door closer. If the door is opened in the direction of arrow 8, this causes on the one hand rotation of the extension arm by the drive shaft and on the other hand rotation and longitudinal displacement of the sliding element 7 in the slide rail 5 in the direction of arrow 9. The mode of operation of the hydraulic overhead door closer as such is already known. The rotation of the drive shaft, via a corresponding conversion mechanism, causes a piston in the door closer to be displaced, which transports a medium filled in the latter from a cylinder space located in front of the piston into a cylinder displaced behind arranged. 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 via a different flow path than when the door is opened, but above all it has to flow through a throttle device when the door is closed, as a result of which the closing takes place more slowly than the normal door opening.

Das Gleitelement 7 besteht beim Ausführungsbeispiel aus einer Achse 10 und einer an deren freiem Ende angeordneten Gleitrolle 11. Wenn man die Verschiebebewegung des Gleitelements in der Gleitschiene beim Öffnen der Tür begrenzt, so kann man die Tür nur bis zu einem dieser Verschiebestrecke entsprechenden Drehwin­kel öffnen. Des weiteren besteht dadurch in vorteilhafter Weise die Möglichkeit, die soweit geöffnete Tür festzustellen. Dies ge­schieht zweckmäßigerweise mittels einer automatisch in Tätigkeit tretenden Feststellvorrichtung 13. Sie weist ein Gehäuse 14 auf, in dem ein Sperrelement 15 in Richtung des Doppelpfeils 16 gegen den Widerstand einer Rückstellfeder 17 verschiebbar gelagert ist. Die Verschiebebewegung ist quer, insbesondere senkrecht zur Längsachse der Gleitschiene 5 gerichtet.In the exemplary embodiment, the sliding element 7 consists of an axis 10 and a sliding roller 11 arranged at its free end. If one limits the sliding movement of the sliding element in the sliding rail when the door is opened, the door can only be opened up to an angle of rotation corresponding to this sliding distance. Furthermore, there is the possibility in an advantageous manner to determine the door which has been opened so far. This is expediently done by means of a locking device 13 that automatically comes into operation. It has a housing 14 in which a locking element 15 is mounted so as to be displaceable in the direction of the double arrow 16 against the resistance of a return spring 17. The displacement movement is directed transversely, in particular perpendicularly to the longitudinal axis of the slide rail 5.

Beim Öffnen der Tür nähert sich das Gleitelement 7 einer Auflauf­schräge 19 des Sperrelements 15, die beispielsweise unter etwa 45° zur Längsachse des Sperrelements gerichtet ist. Schließlich trifft sie auf dieser Auflaufschräge auf und verschiebt das Sperrelement 15 in Pfeilrichtung 20 gegen den Widerstand der Rückstellfeder 17. In Pfeilrichtung 18 schließt sich an die Auf­laufschräge 19 eine Rastaufnahme 21 an. Wenn das Gleitelement 7 vor der Rastaufnahme angekommen ist, springt das federbelastete Sperrelement 15 entgegen dem Pfeil 20 in seine Ausgangslage zu­rück, wodurch eine Verrastung oder Ankupplung stattfindet. Weil nunmehr die Verschiebebewegung des Gleitelements 7 in der Gleit­schiene 5 gesperrt ist, kann die Tür vom Türschließer nicht ge­schlossen werden. Hierbei ist unterstellt, daß die Feder 17 und die Rückstellkraft des Türschließers entsprechend ausgelegt sind.When the door is opened, the sliding element 7 approaches a run-up slope 19 of the blocking element 15, which is directed, for example, at approximately 45 ° to the longitudinal axis of the blocking element. In the end strikes it on this ramp and moves the locking element 15 in the direction of arrow 20 against the resistance of the return spring 17. In the direction of arrow 18, a snap-in receptacle 21 follows the ramp 19. When the sliding element 7 has arrived before the snap-in receptacle, the spring-loaded locking element 15 springs back into its starting position against the arrow 20, as a result of which a locking or coupling takes place. Because the sliding movement of the sliding element 7 in the slide rail 5 is now blocked, the door cannot be closed by the door closer. It is assumed that the spring 17 and the restoring force of the door closer are designed accordingly.

Vorteilhafterweise ist zumindest die der Auflaufschräge 19 zuge­ordnete Kante 22 der Rastaufnahme 21 auch als Auflaufschräge aus­gebildet, jedoch mit einer entgegengesetzt gerichteten Neigung. Wenn also am Gleitelement 7 eine entgegen dem Pfeil 18 wirkende, ausreichend große Kraft angreift, so hat dies abermals ein Ver­schieben des Sperrelements 15 in Pfeilrichtung 20 zur Folge. So­bald das Gleitelement den Höcker 23 überfahren hat und sich voll­ständig außerhalb des Verschiebebereichs des Sperrelements befin­det, kann dieses wieder in die Ausgangsstellung zurückkehren. Diese Auslösekraft rührt von einer von Hand eingeleiteten Schließbewegung der Tür. Nach dem Entkuppeln kann man die Tür freigeben, so daß sie mit Hilfe des Türschließers automatisch ge­schlossen wird.Advantageously, at least the edge 22 of the snap-in receptacle 21 assigned to the run-up slope 19 is also designed as a run-up slope, but with an oppositely directed inclination. If a sufficiently large force acting against the arrow 18 acts on the sliding element 7, this again results in the locking element 15 being displaced in the direction of the arrow 20. As soon as the sliding element has passed over the hump 23 and is completely outside the displacement range of the locking element, the latter can return to the starting position. This release force is due to a manual closing movement of the door. After uncoupling the door can be released so that it is automatically closed with the help of the door closer.

Eine zweite Möglichkeit der Entkupplung von Gleitelement 7 und Sperrelement 15 bzw. der Lösung der Feststellvorrichtung erreicht man durch ein Verschieben des Sperrelements 15 in Pfeilrichtung 20 über eine entsprechende Hilfskraft. Hierbei kann es sich so­wohl um eine Handkraft als auch eine andere bekannte Hilfskraft, beispielsweise eine elektromagnetische Kraft, handeln.A second possibility of uncoupling the sliding element 7 and the locking element 15 or the release of the locking device is achieved by moving the locking element 15 in the direction of the arrow 20 by means of a corresponding assistant. This can be both a manual force and another known auxiliary force, for example an electromagnetic force.

Beim Ausführungsbeispiel ist die wahlweise Auslösung der Fest­stellvorrichtung 13 mittels einer Handkraft vorgesehen. Zu diesem Zwecke ist im Gehäuse 14 der Feststellvorrichtung 13 ein Schiebe­glied 24 im Sinne des Doppelpfeils 25 verschiebbar gelagert. Beim Ausführungsbeispiel verläuft die Führung für das Schiebeglied 24 senkrecht zu derjenigen des Sperrglieds 15. Das Schiebeglied und das Sperrglied sind über eine Lasche oder einen Lenker 26 bewe­gungsmäßig gekoppelt, die über eine Achse 27 drehbar am Sperr­glied 15 und über eine weitere Achse 28 drehbar am Schiebeglied 24 angelenkt ist. Aus Fig. 6 ersieht man, daß in der Sperrstel­lung des Schiebeglieds die Längsachse des Lenkers bzw. eine durch die geometrischen Achsen der Drehachsen 27 und 28 gelegte Gerade mit der strichpunktiert eingezeichneten Längsmittelachse 29 des Sperrglieds 15 oder einer dazu parallelen Linie einen spitzen Winkel einschließt. Demgegenüber bildet die genannte Gerade durch die Achsen 27 und 28 mit einer Längsachse 30 des Schiebeglieds 24 einen überstumpfen Winkel. Beim Ausführungsbeispiel handelt es sich bei dieser Längsachse 13 um eine zu den Längskanten paralle­le gedachte Linie, die seitlich versetzt zur nichteingezeichneten Längsmittellinie des Schiebeglieds 24 verläuft.In the exemplary embodiment, the optional triggering of the locking device 13 is provided by means of a manual force. For this purpose, a sliding member 24 in the sense of the double arrow 25 is slidably mounted in the housing 14 of the locking device 13. In the exemplary embodiment, the guide for the sliding member 24 is perpendicular to that of the locking member 15. The sliding member and the locking member are coupled in terms of movement via a tab or a link 26, which is rotatable via an axis 27 on the locking member 15 and via a further axis 28 rotatable on the sliding member 24 is articulated. From Fig. 6 it can be seen that in the locked position of the sliding member, the longitudinal axis of the handlebar or a straight line defined by the geometric axes of the axes of rotation 27 and 28 with the dash-dotted longitudinal central axis 29 of the locking member 15 or a line parallel thereto includes an acute angle. In contrast, the straight line through the axes 27 and 28 forms an obtuse angle with a longitudinal axis 30 of the sliding member 24. In the exemplary embodiment, this longitudinal axis 13 is an imaginary line parallel to the longitudinal edges, which extends laterally offset to the non-drawn longitudinal center line of the sliding member 24.

Das Schiebeglied 24 ist, wie bereits erläutert, gegen den Wider­stand einer Rückstellfeder 17 beim Ein- und Auskuppeln auslenk­bar. Diese Feder stützt sich einenends an einem Ansatz 31 des Schiebeglieds 24 und andernends an einem Ansatz 32 des Gehäuses 14 der Feststellvorrichtung 13 ab. Bevorzugterweise handelt es sich jeweils um eingepresste Bolzen. Des weiteren kann das Schie­beglied 24 mittels eines drehbaren Betätigungsglieds 33 gegen den Widerstand der Feder 17 verschoben werden. Es ist drehbar im Ge­häuse 14 gelagert und trägt beim Ausführungsbeispiel zwei innen­liegende Exzenter 34. Die Drehachse des Betätigungsglieds ist mit 56 bezeichnet. Die Exzenter 34 liegen an einer Abdrückfläche 35 des Schiebeglieds 24 an, die durch die Innenfläche einer vom Sperrelement 15 entfernten Wand 36 des Schiebeglieds 24 gebildet ist. Jeder Exzenter befindet sich ausgehend von der in Fig. 7 gezeichneten Stellung nach einer 180°-Drehung in einer Totpunkt­stellung. Da jeder Exzenter in eine seitliche Ausnehmung 57 des Schiebeglieds 24 eingreift, ist er in beiden Schieberichtungen formschlüssig gekuppelt. In der Totpunktstellung der Exzenter 34 ist das Sperrelement in seiner wirkungslosen Stellung.As already explained, the sliding member 24 can be deflected against the resistance of a return spring 17 when engaging and disengaging. This spring is supported on one end on a shoulder 31 of the sliding member 24 and on the other end on a shoulder 32 of the housing 14 of the locking device 13. It is preferably in each case pressed-in bolts. Furthermore, the sliding member 24 can be displaced by means of a rotatable actuating member 33 against the resistance of the spring 17. It is rotatably mounted in the housing 14 and carries two internal eccentrics 34 in the exemplary embodiment. The axis of rotation of the actuating member is designated 56. The eccentrics 34 bear against a push-off surface 35 of the sliding member 24, which is formed by the inner surface of a wall 36 of the sliding member 24 remote from the blocking element 15. Starting from the position shown in FIG. 7, each eccentric is in a dead center position after a 180 ° rotation. Since each eccentric engages in a lateral recess 57 of the sliding member 24, it is positively coupled in both sliding directions. In the dead center position of the eccentric 34, the locking element is in its ineffective position.

In nicht gezeigter Weise kann an die Stelle der mechanischen Ver­stellung des Sperrglieds eine elektromechanische bzw. magnetische Verstellung treten. Hierbei ist das Schiebeglied 24 mit dem Anker eines Elektromagneten gekuppelt. Wenn dieser erregt ist, nimmt das Sperrelement seine Sperr- oder Arbeitsstellung ein. Wird der Strom unterbrochen, gibt der Magnet das Sperrglied frei und es wird in eine wirkungslose Stellung verstellt, in welcher sich die Tür durch die Feststellvorrichtung 13 nicht arretieren läßt.In a manner not shown, an electromechanical or magnetic adjustment can take the place of the mechanical adjustment of the locking member. Here, the sliding member 24 is coupled to the armature of an electromagnet. If this is excited, the locking element assumes its locking or working position. If the current is interrupted, the magnet releases the blocking element and it is adjusted to an ineffective position in which the door cannot be locked by the locking device 13.

Aus Fig. 4 ergibt sich, daß die Gleitschiene 5 mit einer Befesti­gungsnut 37 ausgestattet ist, die einen Gleitstein 38 aufnimmt. Er ist mit wenigstens einem Gewinde versehen, in welches eine bzw. jeweils eine Schraube 39 eingedreht ist. Sie durchsetzt eine Wand 40 des Gehäuses 14 der Feststellvorrichtung 13. Wenn die Schraube noch nicht festgezogen ist, so läßt sich die Feststell­vorrichtung 13 senkrecht zur Bildebene der Fig. 4 entlang der Gleitschiene 5 verschieben und an der gewünschten Stelle durch Festziehen der Schraube 39 arretieren.From Fig. 4 it follows that the slide rail 5 is equipped with a mounting groove 37 which receives a sliding block 38. It is provided with at least one thread into which a screw 39 is screwed. It passes through a wall 40 of the housing 14 of the locking device 13. If the screw has not yet been tightened, the locking device 13 can be displaced perpendicular to the image plane of FIG. 4 along the slide rail 5 and locked in place by tightening the screw 39.

Die Gleitschiene 5 wird am festen Rahmen 2 indirekt über eine Montageschiene 41 befestigt. Letztere wird zunächst am festen Rahmen 2 montiert, insbesondere angeschraubt. Ihre Länge ent­spricht zweckmäßigerweise etwa derjenigen der Gleitschiene 5. Die Gleitschiene und die Montageschiene 41 sind formschlüssig gekup­pelt. Zu diesem Zwecke befindet sich an der Gleitschiene eine in Montagestellung nach unten weisende Leiste 42, welche eine in Ge­genrichtung weisende andere Leiste 43 der Montageschiene 41 hin­tergreift. Die Gleitschienenleiste 42 ist Teil einer in Quer­schnitt U-förmigen Aufnahme 44 der Gleitschiene 5. Das untere montageschienenseitige Ende der Gleitschiene 5 stützt sich an ei­ner Vorderfläche 46 der Montageschiene 41 ab. Diese verläuft ins­besondere parallel zur Anlagefläche 48 des festen Rahmens 2.The slide rail 5 is attached to the fixed frame 2 indirectly via a mounting rail 41. The latter is first mounted on the fixed frame 2, in particular screwed on. Their length suitably corresponds approximately to that of the slide rail 5. The slide rail and the mounting rail 41 are coupled in a form-fitting manner. For this purpose, on the slide rail there is a bar 42 which points downward in the mounting position and which engages behind another bar 43 of the mounting rail 41 which points in the opposite direction. The slide rail strip 42 is part of a U-shaped receptacle 44 of the slide rail 5 in cross section. The lower end of the slide rail 5 on the mounting rail side is supported on a front surface 46 of the mounting rail 41. This runs in particular parallel to the contact surface 48 of the fixed frame 2.

Die Gleitschiene 5 wird in Pfeilrichtung 49 von oben her auf die angeschraubte Montageschiene 41 aufgesteckt, wobei zur sicheren Führung die Flächen 46 und 48 herangezogen werden. Sobald die U-­förmige Aufnahme 44 die andere Leiste 43 übergriffen hat, ist die Montage der Gleitschiene 5 im wesentlichen bereits vollzogen, so daß sich nunmehr die am Ausstellarm 6 angreifende Kraft der Feder nicht mehr störend auswirken kann. Diese Montagelage muß ledig­lich noch gesichert werden. Dies geschieht mit Hilfe mehrerer in Längsrichtung der Schienen nebeneinander angeordneter Schrauben 47.The slide rail 5 is plugged onto the screwed mounting rail 41 from above in the direction of arrow 49, the surfaces 46 and 48 being used for reliable guidance. As soon as the U-shaped receptacle 44 has overlapped the other bar 43, the assembly of the slide rail 5 has essentially already been completed, so that the force of the spring acting on the extension arm 6 can no longer have a disruptive effect. This mounting position only has to be secured. This is done with the aid of a plurality of screws 47 arranged next to one another in the longitudinal direction of the rails.

An dem dem freien Ende des Gleitelements 7 zugekehrten oberen Steg 50 der Gleitschiene 5 befindet sich eine Längsnut 51, die vorzugsweise als Schwalbenschwanznut ausgebildet ist. Sie kann beispielsweise zum Einsetzen einer Öffnungsbegrenzung ausgenutzt werden, die man darin, ähnlich wie die Feststellvorrichtung 13, einschiebt und festklemmt. Sie kann mit einem ins Schieneninnere ragenden Vorsprung ausgestattet sein, welcher in die Bewegungs­bahn des Gleitelements 7, insbesondere der Gleitrolle 11, hinein­ragt. Durch Verschieben in der Nut 51 kann man auch hier den Be­grenzungswinkel beliebig einstellen.At the upper web 50 of the slide rail 5 facing the free end of the sliding element 7 there is a longitudinal groove 51, which is preferably designed as a dovetail groove. It can be used, for example, to insert an opening limitation which, similar to the locking device 13, is inserted and clamped therein. It can be equipped with a projection protruding into the rail interior, which protrudes into the movement path of the sliding element 7, in particular the sliding roller 11. By moving in the groove 51, you can also set the limit angle here as desired.

Aus Fig. 3 ergibt sich, daß man in die Befestigungsnut 37 bei­spielsweise auch ein Abdeckprofil 52 einschieben kann. In den Steg 53 kann man gemäß Fig. 3 nicht nur eine Befestigungsnut 37 einarbeiten, sondern auch wenigstens eine, vorzugsweise aber zwei elektrische Leiterbahnen 54 und 55 einbringen. Man kann sie zur Stromzuführung ausnutzen, wenn beispielsweise das Sperrelement 15 mittels eines Elektromagneten oder einer anderen elektrisch be­treibbaren Einrichtung zurückgezogen werden können soll. Am Ge­häuse 14 befinden sich entsprechende Stromabnehmer, die bei­spielsweise mit dem Elektromagneten elektrisch verbunden sind. Das Gehäuse 14 kann somit beliebig entlang der Gleitschiene 5 verschoben werden, ohne daß es hinsichtlich der Stromversorgung des Elektromagneten od. dgl. Probleme gibt.From Fig. 3 it follows that you can also insert a cover profile 52 in the mounting groove 37, for example. According to FIG. 3, it is not only possible to incorporate a fastening groove 37 into the web 53, but also at least one, but preferably two Introduce electrical conductor tracks 54 and 55. They can be used for power supply if, for example, the blocking element 15 is to be able to be withdrawn by means of an electromagnet or another electrically operable device. Corresponding current collectors are located on the housing 14 and are, for example, electrically connected to the electromagnet. The housing 14 can thus be moved as desired along the slide rail 5 without there being any problems with regard to the power supply to the electromagnet or the like.
