Description

The invention relates to a device for controlling the closing sequence of two-leaf swing doors, which are equipped with Gleitschienenschließern, wherein the one door is a unterschlagender, so-called passive leaf and the second wing a Überschlagander, so-called scroll.

The device according to the invention is particularly advantageous for such doors, which have to fulfill a security claim, especially for fire doors with so-called panic and escape function.
Due to folds which constitute a projection of one door leaf in front of another door leaf, it is necessary for the proper closing of a two-leaf door to close the wings in the correct order. This is the case when, from the open state, the passive leaf is first brought into the closed position and only then is the active leaf. In order for the fire doors to take place safely even in case of fire, the wings are not only provided with a drive which automatically moves the door in the closed position, but also with a device for controlling the closing sequence, which is intended to cause the two doors automatically in closed in the right order.
If, when the inactive leaf is open, the active leaf also open, for example driven by a spring or hydraulics, executes a closing movement leading the inactive leaf, this closing movement is stopped by the action of the closing sequence control device at a certain opening angle until the inactive leaf in its closing movement, the gate wing hurries far enough ahead to ensure that the correct closing sequence is reliably ensured.
In sliding rail door closers, a swivel arm projects from a door leaf to a sliding block, which in one at the upper frame part the door frame arranged slide rail is mounted longitudinally movable. With the door closed, that end of the swivel arm which is fastened to the door leaf lies closer to the pivot axis of the door leaf than that end of the swivel arm which is connected to the sliding block. During the majority of the closing pivoting movement of the door leaf, the sliding block slides in the slide rail away from the axis of rotation of the door leaf.
It is customary to use the movement of the sliding blocks of the individual door leaves for controlling the closing sequence and to keep or release this movement appropriately. When the inactive leaf is opened, the movement of the sliding block of the active leaf during the closing of the active leaf at a barrier is blocked. When the inactive leaf is closed, the lock is released. In most cases, it is envisaged for the release of the lock that a connected to the sliding block of the passive leaf part acts on the barrier of the active leaf.

For example, according to the DE 33 36 739 A1 the sliding block for the inactive leaf and the sliding block for the active leaf are guided in a common slide rail. For the above-described controlling the closing sequence of the two door wings, the movement of the sliding blocks associated with the two door leaves is mutually forcibly associated with their movement. When the inactive leaf is opened beyond a certain minimum opening angle, a possible closing movement of the active leaf is stopped at a certain opening angle by blocking the sliding block connected to the active leaf via a pivoting arm against movement in the sliding rail away from the rotational axis of the active leaf by a holding mechanism. The blocking effect of the holding mechanism is only repealed by closing the inactive leaf by a projecting from the sliding block of the passive leaf in the direction of the holding mechanism of the active leaf part by the movement of the sliding block of the passive leaf comes in contact with said holding mechanism and thereby releases the blocking effect. The construction which is often used per se works satisfactorily only when the sliding blocks of the door leaves move exclusively during the closing movement of the associated door leaves from the axis of rotation of the respective door leaf. In particular, when the axis of rotation of a door leaf and the pivot axis of the swivel arm of the door closer are on different sides of the door leaf-one then speaks of the fact that "the door closer drive is mounted on opposite sides" - reverses the direction of sliding of the door during the last part of the closing movement of a door leaf associated sliding block in the slide to. This then leads to that angle at which the active leaf must be stopped in its closing movement, when the inactive leaf is open, is disturbingly large. The unlocking from this waiting position must namely take place at such a - then quite large - opening angle of the inactive leaf, in which the sliding block of the inactive leaf moves away during the closing movement of the inactive leaf from the pivot axis of the inactive leaf.

The AT 507 862 A1 shows embodiments of Schließfolgesteuerungen of two-leaf, equipped with Gleitschienentürschließern swing doors and several suggestions on how the reversely aligned sliding movement (ie, the rotational axis of the respective door directed towards sliding movement) of a sliding block, which can occur during the last part of the closing movement of the door in question compensated can be. For this purpose, displaced by the rotational movement of the pivot arm of the slide rail door closer a displaceable together with the sliding block in the slide rail relative to the sliding block of the axis of rotation of the door. This shifted relative to the sliding block along the slide part then takes over the switching function for the Schließfolgesteuerung in the construction according to DE 33 36 739 A1 directly held the sliding block. According to the proposals Although the desired compensation effect can be achieved, since the function is nevertheless dependent on the movement of the sliding block in the slide rail, the adjustment can be very difficult for some door geometries.

In the AT 510971 A4 It is proposed to translate the pivoting movement of the pivot arm of the door closer of the inactive leaf in a pivoting movement of a running in the slide along this extending rod about its longitudinal axis. Depending on the angular position of the rod, a connected with her, against movement along the slide supported locking part in the path of movement of the gangway side sliding block or not and thus blocks closing movement of the active leaf or not. An advantage of the construction is that at least the low-wing side, the function is independent of the position of the sliding block in the slide. The disadvantage is that said rod must be made telescopic, their storage in very wide doors is a bit expensive and their stand-wing-side drive causes space problems.

The EP 1 544 398 A2 shows a device for controlling the closing sequence of two-leaf swing doors. A longitudinally displaceably mounted in the slide longitudinally held part is part of a transmission connection between the cause by pivoting movement of the inactive parts with causally by pivotal movement of the active wing moving parts, wherein a transverse transfer member is also guided movably guided in the slide and with the longitudinal transfer member is in gear connection and wherein the transverse transfer member with the sliding block of a door leaf or a slideway-side transmission part entrained in this is Getriebeverbindun. It is part of the transmission connection, that the transverse transfer part and the sliding stone side transmission part are pressed against each other at a contact surface, so that one of the two parts by movement of the other part to movement is zwingbar and / or movement of the one part is blockable by blocking movement of the other part, wherein the direction in which optionally the forced movement of the transverse transfer part or the sliding block side transmission part extends and / or wherein the direction of that movement is optionally blocked, one to the longitudinal direction the slide has normal standing directional component. A disadvantage is that direct movement of the sliding block in the longitudinal direction is used as a driving or blocked movement, which again problems arise exactly when the direction of movement of the sliding block reverses during Schleßbewegun the door leaf.

The object underlying the invention is a device for controlling the closing sequence of two-leaf swing doors, - which are equipped with Gleitschienenschließern, wherein the one door is a unterschlagender, so-called passive leaf and the second wing is a sweeping, so-called scroll to provide, wherein locking and releasing the closing movement of the active leaf substantially independently of position and longitudinal movement of the sliding blocks of solid leaf and / or moving leaf is achievable and wherein the rotatable rod according to the AT 510971 A4 associated problems are avoided.

1. a) Ein in der Gleitschiene längsbeweglich gelagert gehaltener hier sogenannter "Längsübertragutigsteil" stellt einen Teil einer Getriebeverbindung dar, über welche ursächlich durch Schwenkbewegung des Standflügels bewegte Teile mit ursächlich durch Schwenkbewegung des Gangflügels bewegten Teile in mechanische Wechselwirkung treten.
2. b) Ein Querübertragungsteil ist ebenfalls in der Gleitschiene geführt bewegbar gelagert. Die Bewegungsführung lässt Beweglichkeit des Querübertragungsteils mit Richtungskomponente zu, welche normal zur Gleitschienenlängsrichtung liegen. Der Querübertragungsteil ist mit dem Längsübertragungsteil derart in Getriebeverbindung, dass Bewegung des einen Teils, Bewegung des anderen Teils bewirkt und/oder umgekehrt.
3. c) Ein hier als "gleitsteinseitiger Übertragungsteil" bezeichneter Teil ist am Gleitstein eines Türflügels geführt beweglich gehalten und wird mit der Gleitbewegung des Gleitsteins in der Gleitschiene mitgeführt. Seine am Gleitstein geführte Beweglichkeit lässt Bewegungen mit Richtungskomponenten normal zur Gleitschienenlängsrichtung zu. Er ist mit dem Querübertragungsteil in Getriebeverbindung bringbar wobei diese Getriebeverbindung das Aneinanderdrücken von Querübertragungsteil und gleitsteinseitigem Übertragungsteil umfasst, wodurch einer der beiden Teile durch den anderen Teil zur Bewegung gezwungen wird oder an Bewegung gehindert wird, wobei zumindest eine der beiden Berührungsflächen mit denen die beiden Teile dabei aneinander anliegen, derart geformt ist, dass sie mit zur Gleitschienenlängsrichtung parallel liegenden Ebenen gerade, zur Gleitschienenlängsrichtung parallel liegende Schnittlinien bildet und wobei die Richtung, in welcher Bewegung eines der beiden Teile erzwungen bzw. blockiert wird, eine zur Gleitschienenlängsrichtung normal stehende Richtungskomponente aufweist.
4. d) Der gleitsteinseitige Übertragungsteil ist mit dem Schwenkarm des zum Gleitstein zugehörigen Türschließers in Getriebeverbindung. Dabei sind alle gegebenenfalls an dieser Getriebeverbindung beteiligten Teile mit der Gleitbewegung des Gleitsteins bezüglich der Gleitschiene mitgeführt.

The object is achieved according to the invention by the following combination of features:

1. a) A longitudinally movably mounted in the slide held here so-called "Längsübertragutigsteil" represents a part of a transmission connection on which causally by pivotal movement of the inactive moving parts with causally caused by pivotal movement of the active leaf parts in mechanical interaction.
2. b) A transverse transfer part is also movably guided guided in the slide rail. The motion control leaves agility of the transverse transmission part with direction component, which are normal to the slide rail longitudinal direction. The transverse transfer member is in gear transmission connection with the longitudinal transfer member such that movement of one member causes movement of the other member and / or vice versa.
3. c) A part referred to herein as a "sliding-block-side transmission part" is movably guided on the sliding block of a door leaf and is carried along with the sliding movement of the sliding block in the slide rail. Its mobility on the sliding block allows movements with direction components normal to the slide rail longitudinal direction. It can be brought into gear connection with the transverse transfer part, wherein this gear connection comprises the pressing together of transverse transfer part and sliding stone-side transfer part, whereby one of the two parts is forced to move by the other part or prevented from moving, wherein at least one of the two contact surfaces with which the two parts thereby abut each other, is shaped so that it forms straight parallel to the slide rail longitudinal planes, parallel to the slide rail longitudinal lines of intersection and wherein the direction in which movement of one of the two parts is enforced or blocked, has a direction normal to Gleitschienenlängsrichtung directional component.
4. d) The sliding-block-side transmission part is in gear connection with the pivot arm of the door closer associated with the sliding block. In this case, all parts that may be involved in this transmission connection with the sliding movement of the sliding block with respect to the slide are entrained.

The combination of the features c) and d) ensures that the required transmission of movements between the wing side part of the mechanism of the closing sequence control and the Stand wing-side part of the mechanics of the closing sequence control over a part - namely the longitudinal transmission part - can be done, which is guided in the slide guided in the longitudinal direction of the slide and yet that the function of the Schließfolgereglung not necessarily dependent on the position of a sliding block in the longitudinal direction of the slide is, but only by the rotation angle of the swing arm of the door closer to the respective sliding stone is necessarily dependent. The use of a longitudinal transmission part is therefore very desirable because it is adaptable to all possible door widths solely by adjusting the length of the longitudinal transmission part, the construction of the closing sequence control.

By the gear connection according to point c in which a transfer surface between two parts is aligned parallel to the longitudinal direction of the slide rail, the function of the closing sequence control in a wide range is independent of the position of the sliding block in the slide rail. As a result, it does not matter whether the sliding movement of the associated sliding block in the slide rail takes place as a result of closing movement of a door leaf or not. The function is dependent only on the pivotal movement of the pivot arm of the door closer belonging to the wing relative to the associated sliding block. (Regardless of whether during the closing movement of a door leaf, the sliding direction of the associated sliding block reverses, the direction of the pivoting movement of the swing arm always remains unchanged.)

• Der Schwenkarm 2 ragt bei geöffnetem Standflügel max. ca. 50° zu dieser von der Gleitschiene 1 ab. Während der Schließbewegung des Standflügels wird der Schwenkarm 2 so geschwenkt, dass sich seine Richtung mehr und mehr der Parallelität zur Gleitschiene 1 annähert. Am Schwenkarm 2 ist ein Aufsatzteil 5 aufgesteckt, welcher an seiner Oberseite (in Fig. 1 nicht sichtbar) eine lokale Erhebung mit schrägen Flanken aufweist. Indem der Schwenkarm 2 mehr und mehr in Richtung Parallele zur Gleitschiene 1 geschwenkt wird, wird der Aufsatzteil 5, welcher nahe an der gleitsteinseitigen Achse 2.1 des Schwenkarms 2 am Schwenkarm 2 befestigt ist, unter den Gleitstein 3 geschwenkt.

Am Gleitstein 3 ist genau an jenem Bereich, unter welchen der Aufsatzteil 5 geschwenkt wird, der gleitsteinseitige Übertragungsteil 4, welcher in diesem Fall die Form eines Bolzens hat, vertikal verschiebbar gelagert gehalten. Sofern der Aufsatzteil 5 nicht unter den gleitsteinseitigen Übertragungsteil 4 geschwenkt ist - was dann der Fall ist, wenn der Standflügel offen ist - befindet sich der gleitsteinseitige Übertragungsteil 4 bezüglich des Gleitsteins 3 in seiner unteren, durch einen Anschlag (nicht dargestellt) definierten Endlage, in welcher er durch sein Eigengewicht und evtl. durch eine elastische Feder (nicht dargestellt) gehalten wird.
Während der Schließbewegung des Standflügels gelangt besagte an der Oberseite des Aufsatzteils 5 befindliche lokale Erhebung an die untere Stirnseite des gleitsteinseitigen Übertragungsteils 4, wodurch der gleitsteinseitige Übertragungsteil 4 relativ zum Gleitstein 3 und damit auch relativ zur Gleitschiene 1 vertikal angehoben wird. Während dieses Anhebens stößt die obere Stirnfläche des gleitsteinseitigen Übertragungsteils 4 von unten her exzentrisch bezüglich dessen Schwenkachse 6.3 an den Querübertragungsteil 6, welcher in diesem Fall ein Schwenkhebel ist, und bewegt diesen in eine Schwenkbewegung nach oben hin.
Der Querübertragungsteil 6 ist über die Schwenkachse 6.3, welche horizontal, normal zur Längsrichtung der Gleitschiene 1 ausgerichtet ist, an der Gleitschiene 1 drehbar gelagert gehalten. Sofern der Querübertragungsteil 6 nicht durch den Bolzen 4 angehoben ist, ist seine untere Fläche 6.1, mit welcher der Bolzen 4 in Kontakt kommen kann, in der Art horizontal ausgerichtet, dass die Schnittlinien dieser Fläche 6.1 mit Ebenen, welche parallel zur Längsrichtung der Gleitschiene 1 ausgerichtet sind, gerade, horizontal und parallel zur Längsrichtung der Gleitschiene 1 ausgerichtet sind.
Die von der Schwenkachse 6.3 abgewandte Stirnfläche des Querübertragungsteils 6 ist eine schiefe Ebene 6.2, deren unterer Flächenbereich weiter vom standflügelseitigen Ende der Gleitschiene 1 entfernt liegt, als deren oberer Flächenbereich. Ein Längsübertragungsteil 7, welcher in diesem Fall eine Schubstange ist, welcher in der Gleitschiene 1 längsbeweglich geführt gehalten ist, ist mit einem Endstück 7.1 versehen, dessen freie Stirnfläche als schiefe Ebene 7.2 ausgebildet ist, die gleich geneigt ist wie die schiefe Ebene 6.2 des Schwenkhebels 6. Die beiden schiefen Ebenen 6.2 und 7.2 liegen aneinander an. Wenn der Querübertragungsteil 6 zufolge der vertikalem Bewegung des gleitsteinseitigen Übertragungsteils 4 nach oben geschwenkt wird, wird über die Getriebeverbindung, welche durch die schiefen Ebenen 6.2, 7.2 zwischen dem Querübertragungsteil 6 und dem Längsübertragungsteil 7 gebildet ist, der Längsübertragungsteil 7 entlang der Gleitschiene 1 vom Querübertragungsteil 6 weg und damit auf die Gangflügelseite der Gleitschiene 1 zu verschoben.
Der Längsübertragungsteil 7 wird damit genau dann auf die Gangflügelseite der Gleitschiene hin verschoben, wenn der Standflügel geschlossen wird. Am gangflügelseitigen Teil der Vorrichtung für die Schließfolgesteuerung muss der Längsübertragungsteil 7 daher dann ein Blockieren der Schließbewegung des Gangflügels in einer Wartestellung bewirken, wenn der Längsübertragungsteil zum Standflügel hin verschoben ist und er muss dieses Blockieren auflösen, wenn er zum Gangflügel hin verschoben ist.With the phrase used repeatedly in this document "parts are in gearbox connection" is meant that two parts, which guided movably on any other parts, interact directly or indirectly over other parts such that a guided movement of one part causes a guided movement of the other part or that blockage of movement of the one part results in an otherwise possible guided movement of the other part blocked.
According to Fig. 1 a pivot arm 2 protrudes from a sliding rail door closer (not shown) attached to a door leaf to a sliding block 3, on which it is held rotatably supported about the axis 2.1. The sliding block 3 is guided longitudinally displaceably guided in a slide rail 1, which typically runs along the upper part of the door frame. The principle of operation is explained on the assumption that the slide rail door closer is mounted on a fixed leaf:

• The swing arm 2 protrudes max. about 50 ° to this from the slide 1 from. During the closing movement of the inactive leaf, the swivel arm 2 is pivoted so that its direction more and more approximates the parallelism to the slide rail 1. On swivel arm 2 an attachment part 5 is attached, which at its top (in Fig. 1 not visible) has a local elevation with oblique edges. By the pivot arm 2 is pivoted more and more in the direction parallel to the slide rail 1, the attachment part 5, which is mounted close to the sliding side axis 2.1 of the pivot arm 2 on the pivot arm 2, pivoted under the sliding block 3.

On Gleitstein 3 is precisely at that area under which the attachment part 5 is pivoted, the sliding stone side transmission part 4, which in this case has the shape of a bolt, held vertically displaceable. If the attachment part 5 is not pivoted under the sliding block side transmission part 4 - which is the case when the passive leaf is open - is the sliding stone side transmission part 4 with respect to the sliding block 3 in its lower, by a stop (not represented) defined end position in which it is held by its own weight and possibly by an elastic spring (not shown).
During the closing movement of the inactive leaf, said local elevation located on the upper side of the attachment part 5 reaches the lower end face of the sliding-block-side transmission part 4, whereby the sliding-stone-side transmission part 4 is lifted vertically relative to the sliding block 3 and thus also relative to the slide rail 1. During this lifting, the upper end face of the sliding block-side transmission part 4 abuts from below eccentrically with respect to its pivot axis 6.3 to the transverse transfer part 6, which in this case is a pivoting lever, and moves it in a pivoting upward.
The transverse transfer part 6 is held rotatably mounted on the slide rail 1 via the pivot axis 6.3, which is aligned horizontally, normal to the longitudinal direction of the slide rail 1. If the transverse transfer member 6 is not raised by the bolt 4, its lower surface 6.1, with which the bolt 4 may come into contact, aligned horizontally in the manner that the cutting lines of this surface 6.1 with planes parallel to the longitudinal direction of the slide rail. 1 are aligned, straight, horizontal and parallel to the longitudinal direction of the slide rail 1 are aligned.
The remote from the pivot axis 6.3 end face of the transverse transfer part 6 is an inclined plane 6.2, whose lower surface area is further away from the low-lying end of the slide rail 1, as the upper surface area. A longitudinal transfer member 7, which is in this case a push rod, which is held longitudinally movably guided in the slide rail 1, is provided with an end piece 7.1, the free end face is formed as an inclined plane 7.2, which is the same inclined as the inclined plane 6.2 of the pivot lever 6. The two inclined planes 6.2 and 7.2 are adjacent to each other. When the transverse transfer part 6 According to the vertical movement of the sliding block-side transmission part 4 is pivoted upwards, via the transmission connection, which is formed by the inclined planes 6.2, 7.2 between the transverse transmission part 6 and the longitudinal transmission part 7, the longitudinal transmission part 7 along the slide rail 1 away from the transverse transmission part 6 and thus moved to the active leaf side of the slide 1 to.
The longitudinal transfer member 7 is thus exactly shifted to the active leaf side of the slide out when the inactive leaf is closed. On the gangway side part of the closing sequence control device, therefore, the longitudinal transfer part 7 must cause the closing movement of the active leaf to be blocked in a waiting position when the longitudinal transfer part is displaced toward the passive leaf and it must release this blockage when it is displaced towards the active leaf.

The transmission connection between the transverse transmission part 6 and the sliding-side transmission part 4 has a contact surface (lower surface 6.1) on which the transverse transmission part 6 and the sliding-side transmission part 4 are pressed against each other, and by moving one part (sliding-side transmission part 4) the other part (transverse transmission part 6) moves is forced.
As described above in feature c), the said contact surface (lower surface 6.1) forms (imaginary) planes which are aligned parallel to the slide rail longitudinal direction, cutting lines which are straight and parallel to the slide rail longitudinal direction. The direction which the movement of the other part (transverse transfer part 6) forced to said contact surface by movement of one part (slide-side transfer part 4) has a directional component which is normal (vertical) to the longitudinal direction of the slide rail 1.

• Es ist damit erreichbar, dass es für die Funktion egal ist, an welchem Längsabschnitt der unteren Fläche 6.1 des Querübertragungsteils 6 sich der gleitsteinseitige Übertragungsteil 4 befindet, wenn er an die untere Fläche 6.1 andrückt. Gegebenenfalls wird jedenfalls die schiefe Ebene 6.2 am freien Stirnende des Querübertragungsteils 6 mindestens um jenes Maß angehoben, um welches der gleitsteinseitige Übertragungsteil 4 gegebenenfalls seinen Berührungspunkt mit der unteren Fläche 6.1 nach oben verschiebt. Es ist ohne weiteres möglich, die Teile der Vorrichtung so auszulegen, dass dieses Anheben jedenfalls ausreicht um zwischen den Zuständen "Schließbewegung des Gangflügels gesperrt" und Schließbewegung des Gangflügels erlaubt" umzuschalten.

Dadurch, dass es egal ist, an welchem Längsabschnitt der unteren Fläche 6.1 des Querübertragungsteils 6 sich der gleitsteinseitige Übertragungsteil 4 befindet, wenn er an die untere Fläche 6.1 andrückt, ist es egal, wenn sich der Gleitstein 3 des Standflügels während des relevanten letzten Teils der Schließbewegung des Standflügels etwas auf die Gangflügelseite der Gleitschiene 1 hin verschiebt oder weg davon. Es braucht nur sichergestellt zu werden, dass er unter der unteren Fläche 6.1 bleibt. Durch Gestaltung der unteren Fläche 6.1 mit ausreichender Länge ist das problemlos realisierbar.As described above in feature d), the sliding-block-side transmission part 4 is in gearbox connection with the pivoting arm 2. In this case, the only on this transmission connection still cooperating transmission part of the attachment part 5; this is carried along with the sliding movement of the sliding block in the slide rail. Although the transmission connection between the stanchion-side device parts and passer-side device parts via the sliding parallel to the slide rail 1 longitudinal transfer member 7, there is motion transmission of moving with the sliding block 3 device parts to device parts which are movably mounted on the slide rail 1, not by transmitting movement in parallel to the slide rail longitudinal direction Direction, but in a direction normal thereto (vertical movement of the transverse transfer member 6) and that, although the sliding block 3 is moved in any case parallel to the slide rail longitudinal direction. This apparent inconvenience brings a significant advantage:

• It is thus achievable that it does not matter for the function at which longitudinal section of the lower surface 6.1 of the transverse transfer part 6, the sliding block-side transmission part 4 is when it presses against the lower surface 6.1. Optionally, in any case, the inclined plane is raised 6.2 at the free end face of the transverse transfer member 6 at least by that amount to which the sliding side transmission part 4, if necessary, moves its point of contact with the lower surface 6.1 upwards. It is readily possible to design the parts of the device so that this lifting sufficient in any case to between the states "closing movement of the active leaf locked" and closing movement of the active leaf allowed "switch.

The fact that it does not matter at which longitudinal section of the lower surface 6.1 of the transverse transfer part 6, the sliding stone-side transmission part 4 is when it presses against the lower surface 6.1, it does not matter if the sliding block 3 of the passive leaf during the relevant last part of the closing movement of the inactive leaf moves slightly towards the active leaf side of the slide rail 1 or away from it. It only needs to be ensured that it remains below the lower surface 6.1. By designing the lower surface 6.1 with sufficient length that is easily realizable.

Fig. 2 shows a pivot arm 12, which alternative to the in Fig. 1 shown swing arm 2 is usable. The pivot arm 12 is pivotally mounted about the axis 12.1 on the sliding block. Close to the sliding side end of the pivot arm 12 of the attachment part 15 is attached to the pivot arm 12. The attachment 15 corresponds in its function to the attachment part 5 of Fig. 1 , In the in Fig. 2 illustrated case, the attachment part 15 is mounted in a transverse to the longitudinal direction of the pivot arm 12 extending guide recess 12.2 and guided in this linearly displaceable. A parallel to the guide recess 12.2 extending threaded bolt 16 extends in the direction of displacement through the attachment part 15 and is rotatably supported on the pivot arm 12. At the attachment part 15 of the threaded bolt 16 in a nut thread in the threaded engagement. By turning the threaded bolt 16 (for example by means of a screwdriver), the attachment part 15 is displaced along the guide recess 12.2. The attachment part 15 projects above the plane of the pivoting arm 12. By the position of the attachment part by means of the threaded bolt 16 is finely adjusted, is also finely adjusted, at which pivot angle of the swing arm 12, a switching operation is triggered in the closing sequence control.

Fig. 3 shows the sliding-stone-side end of a pivot arm 36, which is also alternative to the in Fig. 1 shown swing arm 2 is usable. Coaxially to the sliding-block-side pivot axis of the pivot arm 36, an approximately circular disk-shaped attachment part 35 is connected to the pivot arm 36. From the attachment part 35 protrude two elevations 35.1, which with respect to the axis of the attachment part 35th are arranged symmetrically to each other, parallel to the direction of said pivot axis away from the sliding block. In accordance with the invention, these elevations protrude in the installed situation to the underside of a sliding-block-side transmission part and come there during the pivoting of the pivot arm 36 with the flanks of a downwardly projecting structure in contact, so that they raise the sliding stone-side transmission part on further pivoting of the pivot arm 36. Ideally, the attachment part 35 with respect to angular orientation about the sliding-stone-side axis of the pivot arm 36 is adjustable fixed.

The swivel arm according to Fig. 3 works more robust than those according to Fig. 1 and Fig. 2 and he looks more beautiful too.

Fig. 4 illustrates how the in Fig. 1 designed as a push rod longitudinal transfer member 7 - which is pushed by the closing of the inactive leaf toward the active leaf side of the slide - can be replaced by a longitudinal transfer member 17, which is a rope which is moved by the closing of the inactive leaf in the slide rail to its inactive side.

These are the parts 6, 7 of Fig. 1 through the parts 26 and 17.1 of Fig. 4 replaced, the essential difference being that the inclined planes 6.2, 7.2 at those according to Fig. 1 the parts 6, 7 abut each other, are replaced by oppositely inclined inclined planes 26.2, 17.2 on which the parts 26 and 17.1 of Fig. 4 abut each other.

• Durch das Schließen des Standflügels wird der Längsübertragungsteil 7 parallel zur Gleitschiene 1 auf den Gangflügel zu verschoben (gemäß der aktuellen Überlegung in Fig. 1 also nach rechts). Dabei gleiten die beiden schiefen. Ebenen 7.2 und 6.2 aneinander ab und der Querübertragungsteil 6 wird damit nach unten geschwenkt.

With minor modifications, the operating principle of the device according to Fig. 1 Also usable on the aileron side. Assuming that now the pivot lever 2 of Fig. 1 belongs to the active leaf and not as written to the pinnacle, the essential functional chain of action is outlined linguistically short:

• By closing the inactive leaf, the longitudinal transfer member 7 is moved parallel to the slide rail 1 to the active leaf (according to the current consideration in Fig. 1 so to the right). The two slips glide. Levels 7.2 and 6.2 from each other and the transverse transfer member 6 is thus pivoted down. The lower surface 6.1 of the transverse transfer member 6 is shaped so that it is then horizontally aligned parallel to the slide rail at its longitudinal region facing away from the pivot axis 6.3 and rises obliquely from this region in the form of a ramp to the bearing end. If the sliding block 3 is then under the horizontal part of the lower surface 6.1 or slides there, the sliding stone side transmission part 4 is slightly lowered by the lower surface 6.1 against the action of a spring, which keeps him otherwise in a higher position. When the active leaf is closed, a survey collides on the attachment part 5 of the swing arm 2 with the lower end of the sliding block-side transmission part 4 and the closing movement of the active leaf is stopped until the sliding-stone-side transmission part 4 according to which that the passive leaf is closed slides back up.

The parts groups of Fig. 5 and Fig. 6 both belong to the same device designed according to the invention, it being assumed below that the features according to the invention are realized by the gangway-side parts.
In the slide a housing 8 is used immovably. In the housing 8, which has approximately the shape of a parallel to the slide rail U-profile, a transverse transfer member 9, which could also be referred to as a carriage, guided along curved guide slots 8.1 which are formed in the base surface of the housing as grooves, guided held. On the transverse transfer part 9, the end of the rope formed as a longitudinal transfer member 17 is attached to a receiving opening 9.3, which leads in the slide along this to the passive side part of the device for the Schließfolgesteuerung. If the inactive leaf is closed, this will cause the longitudinal transfer member 17 to move slightly towards the inactive side of the sliding rail (in FIG Fig. 5 to the right) and thus the transverse transfer part 9 in the in Fig. 5 sketched position moves. Without this train, the transverse transfer part 9 would be at the in Fig. 5 bottom surface of the housing 8 (for example, according to its own weight or due to a prestressed elastic spring (not shown) acting on it.) The lower position of the transverse transfer part 9 is shown in FIG Fig. 5 indicated by dotted lines.
Due to the train of the longitudinal transfer member 17 according to the opening of the inactive leaf, the transverse transfer member 9 is not only pulled closer to the other side position of the stationary leaf side of the slide rail, but also transversely to the longitudinal direction of Slide rail slightly moved. The transverse transfer part 9 has a surface 9.1 which, like the lower surface 6.1 of the transverse transfer part 6 of FIG Fig. 1 with planes which are parallel to the longitudinal direction of the slide, forming cut lines which are straight and are aligned parallel to the slide rail longitudinal direction.
One with the sliding block 13 ( Fig. 6 ) of the active leaf along the slide along moving rod 10 which is rotatably supported on the sliding block 13 about its longitudinal axis, is provided at its end facing away from the sliding block 13 of the active wing end portion with a transmission part 11, which is described as radially projecting from the rod 10 cam can.
When the inactive leaf is open, the transverse transfer part 9 is in the in Fig. 5 in full line position. Now, if the active leaf is closed, the sliding block 13 of the active leaf and with this moves the rod 10 with the sliding stone side transmission part 11 to the housing 8, and laterally along this, so that the sliding stone side transmission part 11 with the pivoting ramp 9.2, which with the transverse transfer member 9 is connected, comes into contact. By further closing the moving leaf, the sliding-block-side transmission part slides upwards along the pivotable ramp 9.2, whereby the rod 10 is rotated about its longitudinal axis. After the sliding-block-side transmission part 11 has passed the pivotable ramp 9.2, it touches the surface 9.1 and slides along it without further pivoting, since the surface 9 is aligned parallel to the slide rail.
By rotating the rod 10 about its longitudinal axis to a certain position, a mechanism is provided which stops the closing movement of the active leaf in a waiting position until the rod 10 is turned back again. An exemplary embodiment of this mechanism is described below.

When the inactive leaf is closed, the transverse transfer part 9 is in the in Fig. 5 indicated by dotted lines position. When doing the active leaf is completely or almost completely closed, the sliding stone-side transmission part 11 is located on the surface 9.1 of the Querübertragurlgsteils 9. If now the inactive leaf is opened, so that the transverse transmission part 9 in the in Fig. 5 raised position shown in whole lines. The active leaf is forcibly something co-opened; at least because it has a fold overlapping the inactive leaf; by this opening of the active leaf of the sliding block of the active leaf is moved approximately along the slide rail, this movement at the beginning of the opening movement of the active leaf also something on the solid side of the slide can be aligned, at larger opening angle of the active leaf in any case towards the active leaf side of the slide out is aligned. The sliding-block-side transmission part 11 slides along the surface 9.1 along the transverse transmission part 9 and regardless of which longitudinal region of the slide it is located about an axis parallel to the slide rail (rod 10) rotated because the surface 9.1 due to the movement of the transverse transmission part 9 normal is moved to the longitudinal direction of the slide rail. As mentioned above, this mechanism is made effective, which optionally stops the closing movement of the active leaf in a waiting position until the inactive leaf is at least almost completely closed.

• Fig. 6 ist eine Schnittansicht durch den gangflügelseitigen Gleitstein 13 der zur Vorrichtung von Fig. 5 gehört. Die Schnittebene liegt dabei normal zur Schwenkwelle 14 des gangflügelseitigen Schwenkarms des Türschließers (nicht eingezeichnet).

To understand how point d) of the above-outlined inventive principle is realized on must Fig. 6 will be discussed in more detail:

• Fig. 6 is a sectional view through the transition wing-side sliding block 13 of the device of Fig. 5 belongs. The cutting plane is normal to the pivot shaft 14 of the swing door side arm of the door closer (not shown).

The sliding block 13 is a kind of housing, in which several parts are kept movably guided: The parallel to the slide rail 10 is rotatable about its own longitudinal axis. To the normal axis of the pivot shaft 14 to the pivot shaft 14, a roller cage 20 and a bearing member 27 are pivotable. On the roller cage 20 clamping rollers 25 are rotatably supported, wherein the axes of rotation of the clamping rollers are parallel to the axis of the pivot shaft 14.
The rod 10 is in gear engagement with the roller cage 20, for example via two intermeshing bevel gear teeth, so that rotation of the rod 10 about its longitudinal axis causes pivotal movement of the roller cage 20 about the axis of the pivot shaft 14. The pinch rollers 25 are in each case a recess 27.1 of the bearing part 27, which is open to the pivot shaft 14, rolled in the circumferential direction of the lateral surface of the pivot shaft 14 along. The radial distance of the bottom of the recesses 27.1 to the lateral surface of the pivot shaft increases along a circumferential direction (in Fig. 6 clockwise), so that the pinch rollers 25 are finally clamped between the lateral surface of the pivot shaft 14 and the bottom of a recess 27.1 and thereby form a connection between the pivot shaft 14 and the bearing member 27, by which rotational movement of the pivot shaft 14 in a clockwise direction relative to the bearing part 27 is blocked.
This is between the rotational movement of the sliding block 13 guided on the movable rod 10 and the rotational movement of the sliding block 13 guided pivoting pivot shaft 14, which is optionally swung with the pivotal movement of the pivot arm of the gangway side door closer, made a transmission connection. Through this transmission connection is blockage of movement of the sliding block-side transmission part 11 (which is rigidly connected to the sliding block 13 rotatably mounted rod 10) an otherwise possible guided movement of the pivot arm of the Door closer - which is rigidly connected to the pivot shaft 14 - blocked. Thus, point d) of the inventive principle set forth above is realized.
The advantage here is that the blocking of the pivotal movement of the pivot shaft 14 and thus the pivoting of the swing arm of the door closer takes place only in one direction and that the blocking does not depend on movements of the sliding block 13 along the slide, as long as the sliding stone side transmission part 11 parallel to the slide rail Area 9.1 is present. If the active leaf is opened so far that the sliding stone side transmission part 11 is no longer abutting the surface 9.1, because the sliding block of the active leaf away too far from the housing 8 in the slide, no blockage effect on mobility of the active leaf is necessary or desirable because so in any case, the active leaf is opened beyond the waiting position of the closing sequence control.
The oblique surface 8.2 on the housing 8 serves to rotate the rod 10 in any case so that it completely removes the blockage of the pivoting of the pivot shaft 14 when the active leaf is opened so far that the sliding stone-side transmission part 11 is moved away from the housing 8.

Fig. 7 relates to an advantageous anchoring of the slide rail 1 on a wall (frame), and the displaceable anchoring of the sliding block 13 in the slide rail first
Due to the construction according to Fig. 7 is avoided with little use of material that the slide 1 due to high forces that can be exerted by the sliding block 13 on them, is disturbed highly elastic or even plastically deformed. This is especially important if construction methods like in Fig. 6 sketched to be realized, in which the closing movement of the active leaf is intercepted by the closing sequence control at the waiting position of the active leaf by pivoting the pivoting arm belonging to the side door closer arm in the sliding block of the active leaf is blocked by pivoting of the sliding block side bearing pin 14 is blocked relative to the sliding block.
The slide rail 1 is a kind of U-profile, which is normally arranged with a horizontal profile direction, and downwardly open profile side, wherein a side surface faces a frame, on which the slide rail is mounted.
In the illustrated advantageous embodiment, the slide rail 1 is connected via mounting bracket 29 with the stationary frame. A vertical leg of a mounting bracket 29 abuts against the frame and the second, horizontal leg of the mounting bracket 29 extends above the slide rail 1 at its overhead base. With the upper leg of the mounting bracket, the slide rail 1 is connected by screws 31 which extend through the base of the slide rail 1 in the upper leg of the mounting bracket.
With the frame-side leg of the mounting bracket, the slide rail 1 is connected by at least two vertically superimposed entanglements, which are each formed by one of the slide rail 1 frame side upwardly projecting wall 1.1 is engaged behind by a wall 29.1, which on the slide rail side facing of the frame-side leg of the mounting bracket 29 protrudes downward. This entanglements cause the slide 1 can not move away from the frame-side leg of the mounting bracket 29.
The mounting bracket 29 is connected to the frame by a screw 32 which extends through the frame-side leg of the mounting bracket into the frame, without having to pass through a wall of the slide rail 1. Thus, the construction is easy to install and it can be arranged along the slide so many mounting brackets, as it makes sense statically. The sliding block 13 is held in the profile cavity of the slide rail 1 not only against movement normal to the profile direction of the guide rail 1, he is also so with the frame side side wall the slide 1 hooked that it could be moved laterally away from the frame by forces, by which it is held by the entanglement on the frame-side side wall of the slide rail 1. The said Verhakung is formed by the sliding block 13 on the frame side, a wall 13.1 protrudes downwards, which is engaged behind by one of the frame-side wall 1.2 of the slide rail 1 on the side facing away from the frame side. If there were no such entanglement, would push at large forces through which the sliding block of the frame away from the side wall facing away from the frame of the slide, this side wall bent away from the frame and thus bulging the slide rail.

Fig. 8 shows a further passer-side device according to the invention.
In the slide 1 is described as about plate-shaped rocker transverse transfer member 19 is guided guided movably. For this purpose, the transverse transfer member 19 is connected via two pairs of parallel aligned, equal length pivoting levers 19.2 with the slide rail 1, wherein the pivot lever 19.2 are held pivotally mounted both on the slide rail 1 and the transverse transfer member 19. The running as a rope longitudinal transfer member 17 is connected at one end to a receiving opening 19.3 with the transverse transfer member 19 and leads in the slide rail 1 to the lower side part of the mechanics of Schließfolgesteuerung.
The transverse transfer member 19 is the longitudinal transmission member in gearbox, compared to the slide 1 also guided normal to the longitudinal direction of the slide rail 1 and has a surface 19.1, the lines of intersection with the slide rail 1 parallel planes straight, parallel to the slide rail sections, the surface 19.1 contact surface to the sliding block 23 movably guided sliding stone side transmission part 24, which in this case (again) is a sliding on the sliding block 23 vertically bolt.
In the specific embodiment of Fig. 8 a sliding sleeve 21 is attached to the pivot arm 22 of the gangway-side door closer drive 28, which extends almost over the entire length of the pivot arm 22 and with respect to this longitudinally displaceable. At the sliding side end protrudes from the sliding sleeve 21, a latching projection 21.1 upwards away. At the closing drive end end protrudes from the sliding sleeve 21, a locking projection 21.2 downwards away.
If, due to the position of the inactive leaf, the longitudinal transfer member 17 has been moved somewhat in the direction of the inactive side of the slide rail 1, the transverse transfer member 19 is lowered somewhat vertically relative to its other position. Now, if the active leaf is pivoted in an opening angle range in which the sliding block 23 on the sliding side sliding part 24 passes under the surface 19.1 of the transverse transfer member 19, the upper end surface of the sliding stone side transmission member 24 comes into contact with the surface 19.1 whereby the sliding stone side transmission member 24 against its other position is lowered approximately (against the action of a biased spring, not shown). When closing the pivoting movement of the active leaf of the locking projection 21.1 comes into contact with the lower end face of the sliding block-side transmission part 24, whereby the sliding sleeve 21 is moved relative to its other position in the longitudinal direction of the pivot arm 22. As a result, the locking projection 21.2 comes with a switch knob 28.1, which protrudes from the housing of the gangway side door closer drive 28 upwards, in contact and pushes this button 28.1 down.
By this pressing of the switch knob 28.1, the rotational movement of the drive-side pivot shaft 28.2 of the pivot arm 22 in the direction of the wing-side door closer drive 28 in that direction, through which the active leaf would be driven to the closing movement, stopped.
There are a variety of possibilities for the mechanism by which this stopping is accurately accomplished. In the case that the Türschließerantxieb 28 has a hydraulic drive, a hydraulic valve can be closed by the switch knob, whereby movement of the pivot shaft 28.2 is stopped at least in one direction. But it can also be a unidirectional brake, such as a band brake, which acts between the housing of the door closer drive 28 and the pivot shaft 28.2, are attracted to it or it can be a locking lug a locking member pressed on a possibly rotated with the pivot shaft 28.2 gear and thus movement block the gear and thus the pivot shaft at least in one direction or it can be a mechanism of the kind as in Fig. 6 sketched to be applied with pinch rollers.

Fig. 9 shows a further passer-side device according to the invention. With respect to the parts located on the slide rail 1 and on the moving leaf-side sliding block 23, the device of Fig. 9 identical with that of Fig. 8 , With the construction of Fig. 8 is further common in that the closing movement of the active leaf is blockable by pivotal movement of the wing-side pivot arm 33 of the door closer is optionally blocked by pivotal movement of the drive-side pivot shaft 38.2 is blocked on the door closer drive 38.
In contrast to the construction of Fig. 8 the transmission from the movement of one end of the pivot arm 33 to the other end of the pivot arm 33 is not via a longitudinally displaceable sliding sleeve 21, but via a two-sided pivot lever 34. The pivot lever 34 is pivotally mounted on the pivot arm 33 by means of a pivot pin 34.3, which approximately in the Longitudinal center of the pivot lever 34 and the pivot arm 33 is arranged and aligned horizontally, normal to the longitudinal direction of the pivot arm 33 is. For example, by a spring and a stop surface of the pivot lever 34 is held in the absence of other effects in a position parallel to the pivot arm 33.
At the sliding side end protrudes from the pivot lever 34, a projection 34.1 upwards. At the drive end end of the pivot lever 34 projects a projection 34.2 down to a (not shown) switching part on a arranged on the door closer drive 38 switchable locking part 38.1.

If - as in Fig. 8 with regard to causes detailed executed - in closing pivotal movement of the active leaf and lowered sliding stone side transmission part 24 of the projection 34.1 comes into contact with the lower end face of the sliding block side transmission part 24, the pivot lever 34 is rotated about the pivot pin 34.3, whereby the drive-side projection 34.2 with the switchable locking part 38.1 is disengaged. As a result, the locking part 38.1 switches over so that previously released in both directions pivotal movement of the pivot shaft 38.2 of the pivot arm 33 relative to the door closer drive 38 is now blocked with respect to that direction in which the active leaf would be closed.
For the mechanism of how this stopping can be done in detail, apply to the same topic too Fig. 8 information provided.

Ideally, the transmission connection according to the invention between the movement of a swivel arm of the door closer and the longitudinal transmission part (which forms the connection between gangflügelseitiger and stand-wing-side mechanism) is realized both side of the wing and pitch side. However, it may also be sufficient to realize them only on the side of the wing and to apply a manner of construction according to the state of the art on the moving leaf. This may be useful if the inactive leaf is very narrow and the active leaf is quite wide, which only those geometrical conditions are present at the inactive leaf where many of the conventional Devices for the transmission of motion are not applicable or only with very large disadvantages.
