Unlocking via the panic button must also be possible when the door is pressurized, i.e. H. if the door is pressed at the same time and the locking elements are thus pressed into or against the locking bar on the frame. Especially in panic situations with several people, there is a risk that a first person z. B.
- An espagnolette lock with an additional locking mechanism with a swivel bolt is used e.g. B. in the DE 43 23 341 A1 described.
- a driver provided on the drive rod connecting slide is used to control the swivel bolt engages as a pin in a recess of the swivel bolt.
- espagnolette locks are known in which the swing bolt is coupled to the slide via a toggle lever construction (cf. e.g. EP 2 322 744 A1 ).
- the DE 44 12 690 A1 discloses an espagnolette lock in which the hook bolt is coupled to the slide via a special transmission pivoting lever with a drive pin.
- Additional locks with pivot bolts and different constructions for coupling the pivot bolt to a longitudinally displaceable slide in the lock housing are from DE 20 2018 103 048 U1 , DE 200 17 799 U1 , DE 10 2005 000 132 A1 , DE 20 2011 103 779 U1 , DE 10 2012 203 051 A1 and the DE 20 2008 009 023 U1 known.
- a locking unit of the type described above in which the lock housing z. B. in the housing base and in the housing cover each has a first cam and the swivel bolt has a second cam, these cams being designed as recesses or openings and a cylindrical bolt being provided as the coupling element, which engages on the one hand in the first cams of the lock housing and on the other hand, the second control cam penetrates through the swivel bolt and is displaced in the longitudinal direction via the slide or a fork-shaped driver connected to it is used to pull in the swing bolt.
- the control curves are optimized in such a way that the swing bolt is quickly drawn in during the longitudinal displacement of the slide via the connecting rods.
- the embodiment known from practice has proven itself, but it can be further developed.
- the invention teaches in a generic locking unit of the type described above that the coupling element, which engages on the one hand in the first cam in the lock housing and on the other hand in the second cam in the swivel bolt, in the section (or longitudinal section) in which it engages in the second control curve of the swivel bolt, has a control cross section that deviates from the circular shape and is therefore "non-circular".
- a coupling element can, for. B. be realized in that it has a cam shape or has a cam-shaped cross-section in the longitudinal section in which it engages in the cam in the pivot bolt.
- the cam-shaped cross-section can, for. B. be formed by a round basic shape with an eccentrically projecting cam tip.
- the invention is based on the finding that the kinematics of the swivel bolt can be optimized in a particularly simple manner by modifying the geometry of the coupling element, in particular during pivoting or unlocking, by the coupling element, which on the one hand in the Cams of the lock housing and on the other hand engages in the cam of the swing bolt, with a non-round, z. B. is equipped with a cam-like cross-section, specifically in the longitudinal section of the coupling element in which it engages in the control cam of the swivel bolt.
- the kinematics of the pivot bolt during pivoting is optimized not only by the geometry of the cams in the lock housing on the one hand and in the pivot bolt on the other hand, but also by the geometry of the coupling element, which is preferably a "free" coupling element that is not rigidly attached is attached to the slide, but is not only displaced with the slide in the longitudinal direction in the course of the actuation of the slide, but is also movable relative to the slide, preferably in a direction transverse to the longitudinal direction of the slide, so that the coupling element in the course of the Unlocking can pass through the cams in the lock housing properly and is movable relative to the slide.
- the coupling element which is preferably a "free" coupling element that is not rigidly attached
- the coupling element is held on the slide in such a way that the coupling element is taken along with the slide in the longitudinal direction during unlocking and can (at the same time) be displaced transversely to the longitudinal direction.
- the slide z. B. have a recess or receptacle in which the coupling element is displaceable in the transverse direction, wherein the transverse direction does not have to be aligned exactly perpendicular to the longitudinal direction, but can also be oriented obliquely thereto.
- This recess does not have to be arranged directly on the slide, but the slide can also be equipped with an additional driver, ie a driver (rigid) can be attached to the slide, which has a receptacle, e.g. B. has a fork-shaped receptacle or recess in which the coupling element is guided, z. B. is displaceable transversely to the longitudinal direction.
- the coupling element is particularly preferably secured against twisting and is consequently arranged in a rotationally fixed manner or connected in a rotationally fixed manner to the slide, e.g. B. against twisting secured in the holder of the slide or in the holder of the driver.
- the coupling element is consequently entrained in the course of the longitudinal displacement of the slide in the longitudinal direction and can be displaced transversely to the longitudinal direction without, however, being twisted in the process.
- the coupling element that is essential to the invention is guided in the course of the displacement of the slide in the first control cam (on the lock housing) and optionally in a recess in the slide and engages in the second control cam (on the swivel bolt), so that the kinematics of the swivel bolt are influenced by the geometry of these control curves can be.
- the first cam (on the lock housing) z. B. be crescent-shaped.
- the second control curve (on the swivel bolt) can be angled or L-shaped, with the curvatures of the two control curves being able to be oriented opposite to one another.
- the coupling element according to the invention can basically be implemented in embodiments in which the geometry of the control curves is taken from the prior art. This applies in particular to the cams in the lock housing, ie the coupling element according to the invention can be implemented in a known lock housing with known cams.
- the coupling element according to the invention the kinematics are optimized compared to the known embodiment, without a change in the geometry of the cams being necessary.
- the geometry of the control curve of the swivel bolt is preferably modified and adapted to the geometry of the coupling element.
- the first cam and/or the second cam are preferably designed as openings or recesses in the lock housing and/or in the swivel bolt.
- Other types of cams, z. B. guide rails, webs or other elements can be realized that affect the movement of the coupling element or the movement of the pivot bolt in the course of movement of the coupling element.
- the lock housing preferably has two opposite housing walls, e.g. B. a bottom and a lid. Identical first cams are preferably implemented in each of these housing walls, so that the coupling element is guided at both ends in a first cam in each case in a housing wall.
- the pivoting bolt arranged between the housing walls preferably has an opening as a control cam, ie the coupling element reaches through the pivoting bolt in the region of this opening.
- the coupling element consequently has a specific length, with first longitudinal sections engaging in the control cam in the housing walls and a second longitudinal section arranged in between reaches through the swivel bolt and is consequently arranged in the area of the control curve of the swivel bolt.
- the longitudinal sections that are guided in the first cam can be cylindrical in a basically known manner.
- the second longitudinal section of the coupling element, which is guided in the second control curve or engages in it is equipped with a control cross section that deviates from the circular shape.
- the essential feature of the invention after which the coupling element has a cross-section deviating from the circular shape, therefore preferably refers to a specific longitudinal section of this coupling element, specifically in the area of the second cam.
- the coupling element can be expedient for the coupling element to have one or more guide sections in addition to the length sections already mentioned, which at least in some areas form straight guide surfaces and which z. B. serve to guide the coupling element transversely to the longitudinal direction. These guide sections can guide the coupling element z. B. serve in the recording of the slide or the driver.
- the description of the figures are examples of the coupling element.
- the swivel bolt in the locking unit is of particular importance, in particular in the case of an additional locking of an espagnolette lock.
- This locking unit particularly preferably also has one or more bolt bolts, which are coupled to the slide via a gear in such a way that the bolt bolt is retracted in the course of the displacement of the slide in the longitudinal direction in a transverse direction approximately or substantially perpendicular thereto .
- the coupling element according to the invention is consequently implemented particularly preferably in an embodiment in which a swivel bolt and, on the other hand, one or more bolt bolts are provided.
- the bolt bolts are usually unproblematic in the course of panic actuation because they are bevelled Have ends and a hindrance of the panic operation is not to be feared.
- the geometry of the coupling element ensures that the swivel bolt is drawn in faster than the bolt bolts, so that the function is optimized in the course of a panic operation.
- the additional locking mechanism with a swivel bolt is often used in an espagnolette lock with a central lock, which has a central lock latch and/or a central bolt. Due to the thickness of the latch bolt, the swing bolt does not usually come into contact with the locking bar (on the frame side) during panic operation. The situation may not be optimal if the latch bolt of the center lock slips out of the locking part, since the locking elements of the additional locks are then pressed against the locking part.
- the early retraction of the swivel bolt ensures in a particularly reliable manner that at this point in time when the center lock latch slides out of the locking part, it is pulled back into the area of the bolt bolt or behind it, so that the forces are not released from the swing bolt , but are accommodated by the bolt latches with beveled ends.
- the invention relates not only to the locking unit described, e.g. B. additional lock, but also a multi-point lock, in particular an espagnolette lock, which comprises at least one central lock and at least one locking unit of the type described.
- the locking unit according to the invention is consequently also protected within an espagnolette lock, with the additional locking device or the device arranged therein Slider is coupled to the center lock via a connecting rod that can be moved in the longitudinal direction, so that the additional locks are also unlocked when the center lock is unlocked.
- a motor unit can also be provided, so that unlocking and/or locking by an electric motor can be provided.
- the multi-point lock is preferably designed as a panic lock for an escape door.
- the multi-point lock has at least one actuating element for panic actuation or it is connected to one, the actuating element being designed as a panic button or, particularly preferably, as a panic bar, which, for. B. arranged on a door surface over substantially the entire door width and operable by simply pressing.
- a multiple locking system is shown in the embodiment as an espagnolette lock 1, which is particularly suitable for an escape door with a panic function.
- the multiple locking system has a central lock 2 or central lock and two additional locking units 3, which are attached to the rear of a (common) lock face plate 21, which in turn is attached to a door 4 or a door leaf.
- a so-called panic bar 5 is attached to the door 4 as an actuating element 5, via which all locking elements of the espagnolette lock 1 are retracted, so that the door can be opened quickly and easily in the event of a panic, regardless of the locking status.
- the espagnolette lock (as a motor lock) can optionally have a (not shown) drive, e.g. B. have a motor unit for a motorized operation of the lock, the z. B. can also be attached to the back of the forend as a motor box.
- the additional lock 3, which is in 2 is shown in more detail is coupled via a connecting rod 6 with the center lock 2, ie in the course of actuation of the center lock 2 or in the course of actuation of the panic bar 5, the drive rod 6 is moved in the exemplary embodiment in the longitudinal direction L, specifically for unlocking upwards.
- the locking unit 3 has a lock housing 7 and a slide 8 which is arranged to be longitudinally displaceable in the lock housing 7 and which is also referred to as a connecting slide or lock chain and which is coupled to the drive rod 6 so that the slide 8 is moved with the drive rod in the longitudinal direction L. e.g. B. is moved to unlock the lock up.
- the locking unit 3 has in the lock housing 7 a swivel bolt 10 which is pivotably mounted about a swivel axis 9 and which is coupled to the slide 8 with a coupling element 11 in such a way that the swivel bolt 10, in the course of the displacement of the slide in the unlocking direction E, from a locking position into a locking position is pivoted.
- 2 shows the additional lock 3 in a functional position during unlocking with the swivel bolt 10 partially retracted.
- the locking unit 3 has two bolt bolts 12 in addition to the swivel bolt 10, which are each also coupled to the slide 8 via a gear 13, so that the bolt bolt 12 is retracted in the course of the displacement of the slide 8 in the longitudinal direction L in a transverse direction approximately or essentially perpendicular thereto.
- the bolt bolt 12 is coupled to the slide 8 via a toothed gear or via a toothed gear 13.
- the slide 8 is provided with a toothing 13a, which interacts with a rotatable gear element 13b with toothing, this gear element 13b having the Bolt bolt 12 or a bolt tail 12a of the bolt bolt 12 is actuated by the gear element 13b z.
- This coupling of the bolt bolt 12 with the slide 8 is known from the prior art and is adopted in this case.
- the focus of the invention is the coupling of the swivel bolt 10 to the slide 8 via the coupling element 11.
- This coupling element 11 is guided on the one hand in a first cam 14 in the lock housing 7 and on the other hand it penetrates a second cam 15 in the swivel bolt 10.
- the coupling element 11 out on the slide 8 or on its driver 8a, ie the coupling element 11 is raised in the course of unlocking with the slide 8 and thereby the swivel bolt 10 counterclockwise swung in.
- the lock housing 7 has two opposing housing walls, of which 2 only a housing wall, z. B. the case back is shown.
- the overlying housing cover is not shown.
- the swivel bolt 10 is pivotably fastened between the housing base and the housing cover, and a first cam 14 in the form of a crescent-shaped recess is provided both in the housing base and in the housing cover.
- the coupling element 11 is consequently guided both in the housing base and in the housing cover, in each case in the first control cam 14, and it also extends through the swivel bolt 10 arranged between them the coupling element 11 is not only carried along with the slide 8 in the longitudinal direction L in the course of unlocking, but can also be displaced transversely to the longitudinal direction, so that the coupling element 11 can follow the path of movement of the cams 14 in the lock housing 7.
- the coupling element 11 is not in the form of a cylindrical bolt or cylindrical pin over its entire length, rather the coupling element 11 has a control cross section 16 that deviates from the circular shape in the longitudinal section 11b in which it extends through the swivel bolt, and although in the exemplary embodiment a cam-shaped control cross section.
- This coupling element 11 is in detail in the Figures 3A and 3B shown and the central longitudinal section 11b with a cam-shaped cross-section 16 can be seen. It can also be seen that the coupling element 11 has a first longitudinal section 11a with a cylindrical cross section on both sides, these first longitudinal sections 11a with a cylindrical cross section being guided in the cams 14 of the housing.
- the coupling element 11 has guide sections between the first longitudinal section and the central second longitudinal section 11b 11c with straight or at least partially straight guide surfaces 11d on and via these guide sections, the coupling element is guided in the fork-shaped receptacle 8b of the driver 8a or the slide 8. It can also be seen that the coupling element 11 itself is guided in the fork-shaped receptacle 8b in such a way that the coupling element 11 does not rotate in the course of unlocking or locking, ie the coupling element 11 is guided in the driver 8a such that it cannot rotate but can be moved.
- Figure 4A shows the locking unit according to the invention in the unlocked position with the locking elements 10, 12 fully extended and the slide 8 lowered.
- the slide is raised in the unlocking direction E via the drive rod 6 connected to it, and the locking elements, ie the swivel bolt 10 and the two Bolt latch 12 retracted.
- a comparative view of Figures 4A to 4F shows that the coupling element 11 is guided in the course of the lifting of the slide 8 in the cam 14 in the lock housing 7 and at the same time it engages in the cam 15 in the swivel bolt 10 and pivots the swivel bolt 10 in the process.
- the coupling element or control element according to the invention is drawn in much earlier than in the prior art with a round or cylindrical control pin 11'. This reliably prevents a pivoting bolt element that protrudes too far from getting caught on the locking plate 20 in the course of the panic opening and having to absorb the preload forces.
- the swivel bolt 10 is drawn in at an accelerated rate in relation to the bolt bolts 12, so that the bolt elements 12, which have a much better translation, absorb the forces and thus for a ensure standard-compliant and easy opening of the door element under preload.
- the coupling element according to the invention can be used in principle without modifying the cams in the lock housing.
- the geometry of the cam 15 in the swivel bolt 10 is preferably modified.
- the cam 15 in the pivot bolt 10 has an additional, small depression 18 which can be provided for assembly reasons and/or can interact with the cam tip of the cam element 16 in the course of the kinematics.
- a small recess 19 is provided on the coupling element 11 in the area of the guide surfaces 11d, specifically (also) for assembly reasons, i. H. to be able to mount the cam carriage 16.

Das Mittenschloss ist in der Regel über eine oder mehrere Treibstangen mit der Zusatzverriegelung gekoppelt, und zwar insbesondere mit dem in der Zusatzverriegelung vorgesehenen Schieber, sodass zum Entriegeln und/oder Verriegeln der Zusatzverriegelung die Treibstangen betätigt werden, z. B. über das Mittenschloss oder auch über eine zusätzliche Motoreinheit. Der im Schlossgehäuse der Verriegelungseinheit längsverschiebbar angeordnete Schieber, der z. B. über Treibstangen zum Entriegeln und Verriegeln angehoben und abgesenkt wird, wird in der Praxis auch als Schlosskette oder als Treibstangenanschlussschieber bezeichnet. Der Schwenkriegel, der auch als Hakenriegel oder Schwenkhakenriegel bezeichnet wird, ist derart an den Schieber gekoppelt, dass die Verschiebung des Schiebers in der Schlosslängsrichtung in eine Schwenkbewegung des Schwenkriegels umgesetzt wird, sodass der Schwenkriegel ausgeschwenkt oder eingeschwenkt wird. Die Verriegelungseinheit bzw. das Treibstangenschloss ist in der Regel hinter einem Schlossstulp an einem Türflügel montiert und die Riegelelemente, z. B. der Schwenkriegel greifen in der Verriegelungsstellung in korrespondierende Ausnehmungen oder Elemente ein, z. B. in eine Schließleiste oder ein Schließteil, welches z. B. an einem ortsfesten Rahmenelement oder gegebenenfalls auch an einem Standflügel einer mehrflügeligen Tür angeordnet sein kann. Schwenkhakenriegel zeichnen sich durch ein hohes Maß an Einbruchsicherheit aus. Diese Sicherheit wird optional noch dadurch erhöht, dass die Verriegelungseinheit zusätzlich einen oder mehrere Bolzenriegel aufweisen kann, die oberhalb und/oder unterhalb des Schwenkhakenriegels angeordnet sein können, wobei diese Bolzenriegel z. B. über ein Getriebe derart mit dem Schieber der Verriegelungseinheit gekoppelt sind, dass der Bolzenriegel im Zuge der Verschiebung des Schiebers in der Längsrichtung in einer dazu in etwa oder im Wesentlichen senkrechten Querrichtung eingezogen wird. Bevorzugt handelt es sich bei der Verriegelungseinheit bzw. dem Treibstangenschloss um einen Fluchttürverschluss bzw. Antipanikverschluss mit Panikfunktion, sodass sich das Schloss und damit auch die Verriegelungseinheit von der Türinnenseite stets über ein Panikbetätigungselement, z. B. einen Panikdrücker oder eine Panikstange, entriegeln lässt. Im Zuge der Betätigung des Panikbetätigungselementes werden sämtliche Riegel (und Fallen) der Schließanlage eingezogen, sodass sich die Tür in Gefahrensituationen stets einfach und ohne besondere Entriegelungsmittel, z. B. Schlüssel oder dergleichen, öffnen lässt.The locking unit is, in particular, an additional locking of an espagnolette lock, with the espagnolette lock generally having at least one middle lock or central lock (with central bolt and/or lock latch) and at least one locking unit as an additional locking device, preferably two locking units. The center lock is usually coupled via one or more connecting rods to the additional locking device, in particular to the slide provided in the additional locking device, so that the connecting rods are actuated to unlock and/or lock the additional locking device, e.g. B. via the center lock or via an additional motor unit. The longitudinally displaceable slide arranged in the lock housing of the locking unit, which z. B. via connecting rods for unlocking and locking and lowered is also referred to in practice as a lock chain or connecting rod slide. The swivel bolt, which is also referred to as a hook bolt or swivel hook bolt, is coupled to the slide in such a way that the displacement of the slide in the longitudinal direction of the lock is converted into a pivoting movement of the swivel bolt, so that the swivel bolt is pivoted out or in. The locking unit or the espagnolette lock is usually mounted behind a lock forend on a door leaf and the locking elements, z. B. the swivel bolt engage in the locking position in corresponding recesses or elements such. B. in a lock bar or a locking part, which z. B. can be arranged on a stationary frame member or optionally on a fixed leaf of a multi-leaf door. Hook bolts are characterized by a high degree of burglary security. This security is optionally increased by the fact that the locking unit can also have one or more bolt bolts, which can be arranged above and/or below the swivel hook bolt. B. are coupled via a gear with the slide of the locking unit that the bolt bolt is retracted in the course of displacement of the slide in the longitudinal direction in a transverse direction approximately or substantially perpendicular thereto. The locking unit or espagnolette lock is preferably an escape door lock or anti-panic lock with a panic function, so that the lock and thus also the locking unit can always be actuated from the inside of the door via a panic actuation element, e.g. B. a panic button or a panic bar can be unlocked. In the course of operating the panic control element, all bolts (and latches) of the locking system are retracted, so that the door can always be opened easily and without special unlocking devices, e.g. B. key or the like can be opened.
Die Anforderungen an Fluchttürverschlüsse bzw. Antipanikverschlüsse sind in Sicherheitsnormen geregelt, z. B. in der europäischen Norm EN 1125, wonach in Paniksituationen Fluchttüren auch im verriegelten bzw. abgeschlossenen Zustand von innen immer zu öffnen sind, z. B. durch Druck auf eine sogenannte Panikstange, die an einer Tür über die Breite angeordnet und durch einfaches Drücken betätigbar ist. Die Entriegelung über die Panikbetätigung muss auch dann möglich sein, wenn die Tür unter Druck gesetzt wird, d. h. wenn zugleich gegen die Tür gedrückt wird und die Verriegelungselemente damit in bzw. gegen die Schließleiste am Rahmen gepresst wird. Insbesondere in Paniksituationen mit mehreren Personen besteht die Gefahr, dass eine erste Person z. B. auch bei unübersichtlichen Bedingungen (Dunkelheit und/oder Rauch) gegen die Tür drückt, ohne den Paniktürverschluss zu betätigen und damit die Tür unter Druck setzt, während eine zweite Person (etwas später) die Panikbetätigung, z. B. die Panikstange betätigt, um das Schloss zu entriegeln. In der Praxis muss daher sichergestellt werden, dass sich sämtliche Riegel (und Fallen) zuverlässig durch Panikbetätigung auch dann einziehen lassen, wenn die Riegel durch Druck auf den Türflügel gegen das korrespondierende Schließblech bzw. die Schließleiste gedrückt werden, sodass durch den Druck hohe Reibung zwischen dem Riegel und der Kante des Schließblechs entstehen kann. Bei Bolzenriegeln bereitet dieses in der Regel keine Probleme, da deren Enden zumeist durch eine Fase angeschrägt sind und dadurch leicht aus dem Schließblech herausrutschen. Der Einsatz von Schwenkriegeln, die für Türen mit hohen Sicherheitsanforderungen besonders vorteilhaft sind, kann jedoch hinsichtlich der Funktion in Paniksituationen optimiert werden. - Damit befasst sich die Erfindung.The requirements for escape door locks and anti-panic locks are regulated in safety standards, e.g. B. in the European standard EN 1125, according to which in panic situations escape doors are always to be opened from the inside even when locked or closed, z. B. by pressing a so-called panic bar, which is arranged on a door across the width and can be actuated by simply pressing. Unlocking via the panic button must also be possible when the door is pressurized, i.e. H. if the door is pressed at the same time and the locking elements are thus pressed into or against the locking bar on the frame. Especially in panic situations with several people, there is a risk that a first person z. B. also in unclear conditions (darkness and / or smoke) presses against the door without actuating the panic door lock and thus the door is pressurized, while a second person (slightly later) the panic actuation, z. B. operated the panic bar to unlock the lock. In practice, it must therefore be ensured that all bolts (and latches) can be reliably retracted by panic actuation even if the bolts are pressed against the corresponding locking plate or locking bar by pressure on the door leaf, so that the pressure causes high friction between between the bolt and the edge of the striking plate. In the case of bolt bolts, this does not usually cause any problems, since their ends are usually beveled by a chamfer and therefore easily slip out of the striker plate. However, the use of swing bolts, which are particularly advantageous for doors with high security requirements, can be optimized with regard to their function in panic situations. - This is what the invention deals with.

Der Erfindung liegt die Aufgabe zugrunde, eine Verriegelungseinheit der eingangs beschriebenen Art zu schaffen, die sich bei hoher Einbruch- und Manipulations-Sicherheit und einfachem Aufbau durch eine große Handhabungssicherheit auszeichnet, und zwar insbesondere in Paniksituationen bei Fluchttürverschlüssen.The invention is based on the object of creating a locking unit of the type described at the outset, which is characterized by high security against burglary and manipulation and simple construction by a high level of handling security, particularly in panic situations with escape door locks.
Zur Lösung dieser Aufgabe lehrt die Erfindung bei einer gattungsgemäßen Verriegelungseinheit der eingangs beschriebenen Art, dass das Koppelelement, welches einerseits in die erste Steuerkurve im Schlossgehäuse und andererseits in die zweite Steuerkurve im Schwenkriegel eingreift, in dem Abschnitt (bzw. Längenabschnitt), in dem es in die zweite Steuerkurve des Schwenkriegels eingreift, einen von der Kreisform abweichenden und folglich "unrunden" Steuerquerschnitt aufweist. Ein solches Koppelelement kann z. B. dadurch realisiert werden, dass es in dem Längenabschnitt, in dem es in die Steuerkurve im Schwenkriegel eingreift, eine Nockenform aufweist bzw. einen nockenförmigen Querschnitt aufweist. Der nockenförmige Querschnitt kann z. B. von einer runden Grundform mit einer exzentrisch vorkragenden Nockenspitze gebildet werden.In order to solve this problem, the invention teaches in a generic locking unit of the type described above that the coupling element, which engages on the one hand in the first cam in the lock housing and on the other hand in the second cam in the swivel bolt, in the section (or longitudinal section) in which it engages in the second control curve of the swivel bolt, has a control cross section that deviates from the circular shape and is therefore "non-circular". Such a coupling element can, for. B. be realized in that it has a cam shape or has a cam-shaped cross-section in the longitudinal section in which it engages in the cam in the pivot bolt. The cam-shaped cross-section can, for. B. be formed by a round basic shape with an eccentrically projecting cam tip.
Die Erfindung geht dabei von der Erkenntnis aus, dass sich die Kinematik des Schwenkriegels insbesondere im Zuge des Einschwenkens bzw. Entriegelns auf besonders einfache Weise durch Modifikation der Geometrie des Koppelelementes optimieren lässt, indem das Koppelelement, welches einerseits in die Steuerkurven des Schlossgehäuses und andererseits in die Steuerkurve des Schwenkriegels eingreift, mit einem unrunden, z. B. nockenartigen Querschnitt ausgerüstet wird, und zwar in dem Längenabschnitt des Koppelelementes, in dem dieses in die Steuerkurve des Schwenkriegels eingreift. Die Kinematik des Schwenkriegels im Zuge des Einschwenkens wird erfindungsgemäß nicht nur durch die Geometrie der Steuerkurven im Schlossgehäuse einerseits und im Schwenkriegel andererseits, sondern zusätzlich durch die Geometrie des Koppelelementes optimiert, wobei es sich bevorzugt um ein "freies" Koppelelement handelt, welches nicht starr an dem Schieber befestigt ist, sondern im Zuge der Betätigung des Schiebers nicht nur mit dem Schieber in der Längsrichtung verschoben wird, sondern außerdem relativ zu dem Schieber beweglich ist, und zwar vorzugsweise in einer Richtung quer zur Längsrichtung des Schiebers, sodass das Koppelelement im Zuge der Entriegelung die Steuerkurven im Schlossgehäuse einwandfrei durchfahren kann und dabei relativ zu dem Schieber bewegbar ist. Dazu ist es vorteilhaft, wenn das Koppelelement derart an dem Schieber gehalten ist, dass das Koppelelement im Zuge der Entriegelung mit dem Schieber in der Längsrichtung mitgenommen und dabei (zugleich) quer zur Längsrichtung verschiebbar ist. Dazu kann der Schieber z. B. eine Ausnehmung oder Aufnahme aufweisen, in der das Koppelelement in der Querrichtung verschiebbar ist, wobei die Querrichtung nicht exakt senkrecht zur Längsrichtung ausgerichtet sein muss, sondern auch schräg dazu orientiert sein kann. Diese Ausnehmung muss nicht unmittelbar am Schieber angeordnet sein, sondern der Schieber kann auch mit einem zusätzlichen Mitnehmer ausgerüstet sein, d. h. an dem Schieber kann ein Mitnehmer (starr) befestigt sein, der eine Aufnahme, z. B. eine gabelförmige Aufnahme oder Ausnehmung aufweist, in der das Koppelelement geführt ist, z. B. quer zur Längsrichtung verschiebbar ist. Besonders bevorzugt ist das Koppelelement gegen eine Verdrehung gesichert und folglich drehfest angeordnet bzw. drehfest mit dem Schieber verbunden, z. B. gegen Verdrehung gesichert in der Aufnahme des Schiebers bzw. in der Aufnahme des Mitnehmers geführt. Das Koppelelement wird folglich im Zuge der Längsverschiebung des Schiebers in der Längsrichtung mitgenommen und kann dabei quer zur Längsrichtung verschoben werden, ohne dass es dabei jedoch verdreht wird.The invention is based on the finding that the kinematics of the swivel bolt can be optimized in a particularly simple manner by modifying the geometry of the coupling element, in particular during pivoting or unlocking, by the coupling element, which on the one hand in the Cams of the lock housing and on the other hand engages in the cam of the swing bolt, with a non-round, z. B. is equipped with a cam-like cross-section, specifically in the longitudinal section of the coupling element in which it engages in the control cam of the swivel bolt. According to the invention, the kinematics of the pivot bolt during pivoting is optimized not only by the geometry of the cams in the lock housing on the one hand and in the pivot bolt on the other hand, but also by the geometry of the coupling element, which is preferably a "free" coupling element that is not rigidly attached is attached to the slide, but is not only displaced with the slide in the longitudinal direction in the course of the actuation of the slide, but is also movable relative to the slide, preferably in a direction transverse to the longitudinal direction of the slide, so that the coupling element in the course of the Unlocking can pass through the cams in the lock housing properly and is movable relative to the slide. It is advantageous if the coupling element is held on the slide in such a way that the coupling element is taken along with the slide in the longitudinal direction during unlocking and can (at the same time) be displaced transversely to the longitudinal direction. For this purpose, the slide z. B. have a recess or receptacle in which the coupling element is displaceable in the transverse direction, wherein the transverse direction does not have to be aligned exactly perpendicular to the longitudinal direction, but can also be oriented obliquely thereto. This recess does not have to be arranged directly on the slide, but the slide can also be equipped with an additional driver, ie a driver (rigid) can be attached to the slide, which has a receptacle, e.g. B. has a fork-shaped receptacle or recess in which the coupling element is guided, z. B. is displaceable transversely to the longitudinal direction. The coupling element is particularly preferably secured against twisting and is consequently arranged in a rotationally fixed manner or connected in a rotationally fixed manner to the slide, e.g. B. against twisting secured in the holder of the slide or in the holder of the driver. The coupling element is consequently entrained in the course of the longitudinal displacement of the slide in the longitudinal direction and can be displaced transversely to the longitudinal direction without, however, being twisted in the process.
Das erfindungswesentliche Koppelelement wird im Zuge der Verschiebung des Schiebers in der ersten Steuerkurve (am Schlossgehäuse) und optional in einer Ausnehmung des Schiebers geführt und greift dabei in die zweiten Steuerkurve (am Schwenkriegel) ein, sodass die Kinematik des Schwenkriegels durch die Geometrie dieser Steuerkurven beeinflusst werden kann. Dabei kann die erste Steuerkurve (am Schlossgehäuse) z. B. sichelförmig ausgebildet sein. Die zweite Steuerkurve (am Schwenkriegel) kann winkelförmig bzw. L-förmig ausgebildet sein, wobei die Krümmungen der beiden Steuerkurven entgegengesetzt zueinander orientiert sein können. Bei der Ausgestaltung der Steuerkurven kann auf die aus dem Stand der Technik bekannten Erkenntnisse zurückgegriffen werden, d. h. das erfindungsgemäße Koppelelement lässt sich grundsätzlich bei Ausführungsformen realisieren, bei denen die Geometrie der Steuerkurven aus dem Stand der Technik entnommen ist. Dieses gilt insbesondere für die Steuerkurven im Schlossgehäuse, d. h. das erfindungsgemäße Koppelelement lässt sich bei einem bekannten Schlossgehäuse mit bekannten Steuerkurven realisieren. Durch den Einsatz des erfindungsgemäßen Koppelelementes wird die Kinematik gegenüber der bekannten Ausführungsform optimiert, ohne dass eine Veränderung der Geometrie der Steuerkurven erforderlich ist. Bevorzugt wird die Geometrie der Steuerkurve des Schwenkriegels modifiesziert und an die Geometrie des Koppelelements angepasst. Grundsätzlich besteht die Möglichkeit, die Geometrie der Steuerkurve im Schwenkriegel so zu modifizieren, dass sie sowohl mit dem erfindungsgemäßen Koppelelement als auch mit einem herkömmlichen Koppelelement mit zylindrischen Querschnitt funktioniert, so dass ein universell einsetzbarer Schwenkriegel zur Verfügung gestellt werden kann. Im Vordergrund der Erfindung steht die Ausgestaltung des Koppelelementes, wobei die Steuerkurve in dem Schwenkriegel bevorzugt an diese Geometrie angepasst wird.The coupling element that is essential to the invention is guided in the course of the displacement of the slide in the first control cam (on the lock housing) and optionally in a recess in the slide and engages in the second control cam (on the swivel bolt), so that the kinematics of the swivel bolt are influenced by the geometry of these control curves can be. The first cam (on the lock housing) z. B. be crescent-shaped. The second control curve (on the swivel bolt) can be angled or L-shaped, with the curvatures of the two control curves being able to be oriented opposite to one another. In designing the control cams, the findings known from the prior art can be used, ie the coupling element according to the invention can basically be implemented in embodiments in which the geometry of the control curves is taken from the prior art. This applies in particular to the cams in the lock housing, ie the coupling element according to the invention can be implemented in a known lock housing with known cams. By using the coupling element according to the invention, the kinematics are optimized compared to the known embodiment, without a change in the geometry of the cams being necessary. The geometry of the control curve of the swivel bolt is preferably modified and adapted to the geometry of the coupling element. In principle, there is the possibility of modifying the geometry of the control curve in the swivel bolt so that it can be used with both the coupling element according to the invention and with a conventional coupling element with a cylindrical cross-section works, so that a universally applicable swing bolt can be made available. The focus of the invention is the design of the coupling element, with the control cam in the swivel bolt preferably being adapted to this geometry.
Vorzugsweise sind die erste Steuerkurve und/oder die zweite Steuerkurve als Durchbrechungen oder Ausnehmungen im Schlossgehäuse und/oder im Schwenkriegel ausgebildet. Alternativ können aber auch andere Arten von Steuerkurven, z. B. Führungsschienen, Stege oder andere Elemente realisiert sein, die die Bewegung des Koppelelementes beeinflussen bzw. die die Bewegung des Schwenkriegels im Zuge der Bewegung des Koppelelementes beeinflussen. Bevorzugt weist das Schlossgehäuse zwei gegenüberliegende Gehäusewände auf, z. B. einen Boden und einen Deckel. Bevorzugt sind in jeder dieser Gehäusewände identische erste Steuerkurven realisiert, sodass das Koppelelement an beiden Enden in jeweils einer ersten Steuerkurve in jeweils einer Gehäusewand geführt ist. Der zwischen den Gehäusewänden angeordnete Schwenkriegel weist vorzugsweise als Steuerkurve eine Durchbrechung auf, d. h. das Koppelelement durchgreift den Schwenkriegel im Bereich dieser Durchbrechung. Das Koppelelement hat folglich eine bestimmte Länge, wobei erste Längenabschnitte in die Steuerkurve in den Gehäusewänden eingreifen und ein dazwischen angeordneter zweiter Längenabschnitt durchgreift den Schwenkriegel und ist folglich im Bereich der Steuerkurve des Schwenkriegels angeordnet. Die Längenabschnitte, die in der ersten Steuerkurve geführt sind können in grundsätzlich bekannter Weise zylindrisch ausgebildet sein. Bevorzugt ist jedoch der zweite Längenabschnitt des Koppelelementes, der in der zweiten Steuerkurve geführt ist bzw. in diese eingreift, mit einem von der Kreisform abweichenden Steuerquerschnitt ausgerüstet. Das erfindungswesentliche Merkmal, wonach das Koppelelement einen von der Kreisform abweichenden Querschnitt aufweist, bezieht sich folglich bevorzugt auf einen bestimmten Längenabschnitt dieses Koppelelementes, und zwar im Bereich der zweiten Steuerkurve. Dazu wird auch auf die Figurenbeschreibung verwiesen. Im Übrigen kann es zweckmäßig sein, dass das Koppelelement zusätzlich zu den bereits erwähnten Längenabschnitten ein oder mehrere Führungsabschnitte aufweist, die zumindest bereichsweise gerade Führungsflächen bilden und die z. B. der Führung des Koppelelementes quer zur Längsrichtung dienen. Diese Führungsabschnitte können der Führung des Koppelelementes z. B. in der Aufnahme des Schiebers bzw. des Mitnehmers dienen. Auch dazu wird auf die Figurenbeschreibung verwiesen.The first cam and/or the second cam are preferably designed as openings or recesses in the lock housing and/or in the swivel bolt. Alternatively, other types of cams, z. B. guide rails, webs or other elements can be realized that affect the movement of the coupling element or the movement of the pivot bolt in the course of movement of the coupling element. The lock housing preferably has two opposite housing walls, e.g. B. a bottom and a lid. Identical first cams are preferably implemented in each of these housing walls, so that the coupling element is guided at both ends in a first cam in each case in a housing wall. The pivoting bolt arranged between the housing walls preferably has an opening as a control cam, ie the coupling element reaches through the pivoting bolt in the region of this opening. The coupling element consequently has a specific length, with first longitudinal sections engaging in the control cam in the housing walls and a second longitudinal section arranged in between reaches through the swivel bolt and is consequently arranged in the area of the control curve of the swivel bolt. The longitudinal sections that are guided in the first cam can be cylindrical in a basically known manner. Preferably, however, the second longitudinal section of the coupling element, which is guided in the second control curve or engages in it, is equipped with a control cross section that deviates from the circular shape. The essential feature of the invention, after which the coupling element has a cross-section deviating from the circular shape, therefore preferably refers to a specific longitudinal section of this coupling element, specifically in the area of the second cam. In this regard, reference is also made to the description of the figures. Moreover, it can be expedient for the coupling element to have one or more guide sections in addition to the length sections already mentioned, which at least in some areas form straight guide surfaces and which z. B. serve to guide the coupling element transversely to the longitudinal direction. These guide sections can guide the coupling element z. B. serve in the recording of the slide or the driver. In this regard, too, reference is made to the description of the figures.
Im Übrigen besteht die Möglichkeit, die Geometrie der Steuerkurven und insbesondere die Geometrie der zweiten Steuerkurve in den Schwenkriegel abweichend vom Stand der Technik ebenfalls zu optimieren und z. B. in bestimmten Bereichen an die Geometrie des erfindungswesentlichen Koppelelementes anzupassen.Furthermore, there is the possibility of also optimizing the geometry of the control curves and in particular the geometry of the second control curve in the swivel bolt, in a manner deviating from the prior art and e.g. B. in certain areas to the geometry of the invention-essential coupling element.
Erfindungsgemäß kommt dem Schwenkriegel in der Verriegelungseinheit besondere Bedeutung zu, und zwar insbesondere bei einer Zusatzverriegelung eines Treibstangenschlosses. Besonders bevorzugt weist diese Verriegelungseinheit zusätzlich einen oder mehrere Bolzenriegel auf, der bzw. die über ein Getriebe derart mit dem Schieber gekoppelt sind, dass der Bolzenriegel im Zuge der Verschiebung des Schiebers in der Längsrichtung in einer dazu in etwa oder im Wesentlichen senkrechten Querrichtung eingezogen wird. Das erfindungsgemäße Koppelelement wird folglich besonders bevorzugt bei einer Ausführungsform realisiert, bei der einerseits ein Schwenkriegel und andererseits ein oder mehrere Bolzenriegel vorgesehen sind. Die Bolzenriegel sind im Zuge einer Panikbetätigung in der Regel unproblematisch, da sie abgeschrägte Enden aufweisen und eine Behinderung der Panikbetätigung dadurch nicht zu befürchten ist. Eine Anpassung der Kinematik der Bolzenriegel ist daher in der Regel nicht erforderlich. Erfindungsgemäß wird durch die Geometrie des Koppelelementes jedoch gewährleistet, dass der Schwenkriegel gegenüber den Bolzenriegeln beschleunigt eingezogen wird, sodass die Funktion im Zuge einer Panikbetätigung optimiert wird.According to the invention, the swivel bolt in the locking unit is of particular importance, in particular in the case of an additional locking of an espagnolette lock. This locking unit particularly preferably also has one or more bolt bolts, which are coupled to the slide via a gear in such a way that the bolt bolt is retracted in the course of the displacement of the slide in the longitudinal direction in a transverse direction approximately or substantially perpendicular thereto . The coupling element according to the invention is consequently implemented particularly preferably in an embodiment in which a swivel bolt and, on the other hand, one or more bolt bolts are provided. The bolt bolts are usually unproblematic in the course of panic actuation because they are bevelled Have ends and a hindrance of the panic operation is not to be feared. It is therefore generally not necessary to adapt the kinematics of the bolt latch. According to the invention, however, the geometry of the coupling element ensures that the swivel bolt is drawn in faster than the bolt bolts, so that the function is optimized in the course of a panic operation.
Von besonderer Bedeutung ist dabei in der Praxis, dass die Zusatzverriegelung mit Schwenkriegel häufig in einem Treibstangenschloss mit Zentralschloss eingesetzt wird, welches eine zentrale Schlossfalle und/oder einen Zentralriegel aufweist. Aufgrund der Dicke der Schlossfalle kommt es im Zuge einer Panikbetätigung in der Regel zunächst nicht zu einem Kontakt der Schwenkriegel mit der (rahmenseitigen) Schließleiste. Nicht optimal ist die Situation gegebenenfalls dann, wenn die Schlossfalle des Mittenschlosses aus dem Schließteil rausrutscht, da dann die Verriegelungselemente der Zusatzverriegelungen gegen das Schließteil gedrückt werden. Bei der erfindungsgemäßen Ausgestaltung ist nun durch das frühe Einziehen des Schwenkriegels besonders zuverlässig gewährleistet, dass diese zu diesem Zeitpunkt, in dem die Mittenschlossfalle aus dem Schließteil herausrutscht, bis in den Bereich der Bolzenriegel oder dahinter zurückgezogen ist, so dass die Kräfte nicht von dem Schwenkriegel, sondern von den Bolzenriegeln mit abgeschrägten Enden aufgenommen werden.In practice, it is of particular importance that the additional locking mechanism with a swivel bolt is often used in an espagnolette lock with a central lock, which has a central lock latch and/or a central bolt. Due to the thickness of the latch bolt, the swing bolt does not usually come into contact with the locking bar (on the frame side) during panic operation. The situation may not be optimal if the latch bolt of the center lock slips out of the locking part, since the locking elements of the additional locks are then pressed against the locking part. In the embodiment according to the invention, the early retraction of the swivel bolt ensures in a particularly reliable manner that at this point in time when the center lock latch slides out of the locking part, it is pulled back into the area of the bolt bolt or behind it, so that the forces are not released from the swing bolt , but are accommodated by the bolt latches with beveled ends.
Die Erfindung betrifft nicht nur die beschriebene Verriegelungseinheit, z. B. Zusatzverriegelung, sondern auch eine Mehrfachverriegelung, insbesondere ein Treibstangenschloss, welche zumindest ein Mittenschloss und zumindest eine Verriegelungseinheit der beschriebenen Art umfasst. Die erfindungsgemäße Verriegelungseinheit wird folglich auch innerhalb eines Treibstangenschlosses unter Schutz gestellt, wobei die Zusatzverriegelung bzw. der darin angeordnete Schieber über eine in Längsrichtung verschiebbare Treibstange mit dem Mittenschloss gekoppelt ist, sodass im Zuge der Entriegelung des Mittenschlosses auch die Zusatzverriegelungen entriegelt werden. Alternativ oder ergänzend zu einem Mittenschloss kann auch eine Motoreinheit vorgesehen sein, sodass eine elektromotorische Entriegelung und/oder Verriegelung vorgesehen sein kann. Bevorzugt ist die Mehrfachverriegelung als Panikschloss für eine Fluchttür ausgebildet. Die Mehrfachverriegelung weist zumindest ein Betätigungselement für eine Panikbetätigung auf oder sie ist mit einer solchen verbunden, wobei das Betätigungselement als Panikdrücker oder besonders bevorzugt als Panikstange ausgebildet ist, die z. B. an einer Türoberfläche über im Wesentlichen die gesamte Türbreite angeordnet und durch einfaches Drücken betätigbar ist.The invention relates not only to the locking unit described, e.g. B. additional lock, but also a multi-point lock, in particular an espagnolette lock, which comprises at least one central lock and at least one locking unit of the type described. The locking unit according to the invention is consequently also protected within an espagnolette lock, with the additional locking device or the device arranged therein Slider is coupled to the center lock via a connecting rod that can be moved in the longitudinal direction, so that the additional locks are also unlocked when the center lock is unlocked. As an alternative or in addition to a center lock, a motor unit can also be provided, so that unlocking and/or locking by an electric motor can be provided. The multi-point lock is preferably designed as a panic lock for an escape door. The multi-point lock has at least one actuating element for panic actuation or it is connected to one, the actuating element being designed as a panic button or, particularly preferably, as a panic bar, which, for. B. arranged on a door surface over substantially the entire door width and operable by simply pressing.

Wie bereits erläutert lässt sich das erfindungsgemäße Koppelelement grundsätzlich ohne Modifikation der Steuerkurven im Schlossgehäuse einsetzen.
