Definitions
- the invention relates to a tumbler, i.e. Locking or locking device.
- Tumblers are used, for example, in access protection devices on a movable element that closes an area, such as a door, flap or lid.
- a movable element can be locked or locked by means of a tumbler.
- Access protection devices of this type can be used in many areas, in particular in automation technology. There, for example, access to a system, such as a robot or other mechanical or chemical system, can be restricted by a boundary in which a door or flap is provided, which can be opened, for example, by pivoting or sliding. The door or flap can be locked or locked by a locking element of a tumbler, for example by a locking bolt.
- the locking or locking can be produced or released in a targeted manner by moving the locking element, for example locking bolts, into the desired position by means of a motor.
- a motor for example locking bolts
- an access door can be locked during operation of a system for safety reasons, but allow access when the system is at a standstill for operation, maintenance, etc. by unlocking it.
- the EP 2 295 679 A2 describes a tumbler for a component to close an opening.
- a longitudinally movable bolt is driven by an electric motor via a gear mechanism.
- a sensor is provided which determines the end position of the bolt.
- a controller determines the time it takes for the bolt to move from one end position to the other end position. In this way it can be determined whether the drive can move freely or whether the bolt is blocked.
- a tumbler in which a plunger turns a door as a movable one Part locked or locked.
- a drive drives a rack as a transmission element.
- the transmission element acts on an energy store designed as a spring for moving the plunger. If the plunger is not blocked, it moves due to the force exerted by the spring. If the plunger is blocked, the drive moves the transmission element so that energy is stored in the spring. If the blockage is removed, the plunger snaps into the actuated position due to the spring force.
- a guard locking device in which a drive moves a plunger via an intermediate coupling device.
- the transmission device has a first transmission element, which is coupled by means of a pin to the plunger, which moves in an elongated hole.
- the first transmission element is rotatably mounted and is coupled to a worm gear segment as a second transmission element by a torsion spring. If the drive effects a rotary movement of the second transmission element, the rotary movement is normally immediately converted into a rotary movement of the first transmission element by the spring.
- the ends of the torsion spring rest against stops of the first and second transmission elements.
- the first transmission element cannot rotate, so that the torsion spring is deflected and tensioned. If the blockage of the ram is released, the torsion spring is released. In the event of a blockage when the plunger moves from the unlocked end position into the locked end position, as well as when the plunger is blocked from the locked end position into the unlocked end position, energy is thus introduced into the spring designed as an energy store.
- the DE 10 2005 032 172 A1 describes a tumbler for a component for closing an opening with a cam disk rotatably arranged in a housing.
- a recess located on the circumference is provided for receiving an actuator.
- Another recess on the circumference of the cam is provided for receiving a tappet as a locking element.
- the plunger is made of a housing made of magnetizable material guided and carries an anchor and permanent magnets. By energizing magnetic coils, the armature with the plunger is moved between two end positions.
- the tappet is provided with two elongated holes, the length of which corresponds to the tappet stroke. The elongated holes each hold a pin, with a spring being arranged between the two pins. As a result, the movement of the armature when the tappet is blocked can be converted into a shortening of the length of the springs.
- the tumbler comprises a locking element that is movable in a closing direction, for example a locking bolt that is displaceable in its longitudinal direction in the closing or opposite opening direction, at least between a closed position in which a part of the locking element with a receiving element, for example a receiving opening, cooperates to form a lock, and an open position in which the closure element releases the lock.
- a locking element that is movable in a closing direction, for example a locking bolt that is displaceable in its longitudinal direction in the closing or opposite opening direction, at least between a closed position in which a part of the locking element with a receiving element, for example a receiving opening, cooperates to form a lock, and an open position in which the closure element releases the lock.
- the tumbler comprises a drive with a transmission element for moving the closure element.
- the transmission element is coupled to a motor via a gear for displacement in the longitudinal direction.
- the drive preferably provides a motor for the rotary drive, which is coupled, for example, by means of a toothed rack or drive spindle for displacing the transmission element in the closing direction.
- the use of an electric motor with a corresponding gear is particularly preferred.
- the transmission element is coupled to the closure element in terms of movement or force, so that the transmission element can be moved together with the closure element in a first direction of movement parallel to the closing direction and a second, opposite direction of movement.
- This movement is preferably a linear movement, so that the transmission element and the closure element can be moved linearly together via the coupling.
- the coupling is designed according to the invention so that it is spring-biased in both directions of movement under prestress. Regardless of whether the closure element is to be moved by the drive via the transmission element and the coupling in the closing direction or in the opposite opening direction, a spring acts via the coupling, so that when the closure element is blocked, the transmission element moves in one of the directions of movement against a spring force around a suspension travel is possible.
- the coupling is pretensioned so that the deflection around the spring travel is only possible when the pretension is overcome.
- the solution according to the invention thus significantly reduces the risk of damage when the closure element is blocked.
- Very high impacts do not then act directly on the transmission element and the drive, but lead to the coupling being triggered with a movement around the spring deflection while overcoming the preload.
- the pretensioning can limit the triggering of the coupling to the actually acting high forces in the event of a blockage, while the coupling can be adjusted by suitable selection of the pretensioning so that it behaves rigidly in normal operation.
- the movement of the closure element is preferably largely synchronized with the movement of the transmission element.
- the closure element can be moved in the closing direction by a maximum travel path, which can be limited by the design and configuration of the drive and the transmission element, but also by correspondingly controlling the drive.
- the maximum travel distance can be, for example, 5 - 50 mm, in some applications, for example, 10 - 30 mm.
- the maximum spring travel of the coupling can be limited, for example by design, for example by the distance between two Attacks.
- the maximum travel of the coupling can preferably be chosen to be small, for example less than 50% of the maximum travel.
- An even narrower limitation of the maximum spring travel to, for example, 25% or less of the maximum travel path, particularly preferably 10% or less, is preferred for a coupling that is as synchronous as possible.
- the maximum spring travel can be limited to a few mm, while still achieving the goal of preventing damage in the event of a blockage.
- a very compact coupling design can be achieved by limiting the maximum spring travel.
- At least one coupling element is provided for realizing the coupling, said coupling element being movable, in particular preferably displaceable, both in relation to the transmission element and in relation to the closure element in at least one of the movement directions.
- At least one drive stop is preferably formed on the transmission element and at least one lock stop is formed on the closure element, the movement being limited by abutment of the coupling element against these stops.
- at least one spring is preferably provided in order to act on the coupling element in the direction of these stops.
- At least one first and one second coupling element are provided, both of which are movable, preferably displaceable, both with respect to the transmission element and with respect to the closure element, and that a compression spring acts between the coupling elements.
- the coupling by means of an interposed coupling element, on which a spring acts, enables the desired decoupling between the closure and transmission element.
- the use of two coupling elements enables decoupling on both sides with a simple construction. While multiple springs can be used to generate the spring force, the construction is significantly simplified by using a single compression spring between the coupling elements.
- Such a compression spring should preferably act within the coupling in both directions of movement and thus provide the desired spring force, regardless of whether it acts in the closing or opening direction.
- the compression spring can more preferably be used for production be biased according to the desired bias, more preferably between the first and second coupling elements. In this way, the desired transmission characteristics of the coupling can be achieved with a very simple mechanical construction.
- At least a first and a second closure stop are provided on the closure element, each for a first and a second coupling element. At least two stops can also be provided on the transmission element, a first drive stop for the first coupling element and a second drive stop for the second coupling element.
- the coupling elements are preferably arranged between the stops, namely between the first closure stop and the first drive stop on one side and the second closure stop and the second drive stop on the opposite side.
- a compression spring is provided between the coupling elements, which is further preferably biased to act on the first coupling element in the direction of the first closure stop and the first drive stop and the second coupling element in the direction of the second closure stop and the second drive stop.
- the stops enable the desired pretension in both directions, while the desired decoupling is ensured by the coupling elements which are acted upon by the spring.
- the closure element is preferably designed as a bolt, for example with a round cross section.
- the coupling elements can be designed such that they encompass the closure element, for example as sleeves.
- the transmission element can also be designed to encompass the closure element, for example as a cage. It is then particularly preferred that at least one spring and at least one, preferably two, coupling elements are arranged within the cage. Stops for the coupling elements can be provided on the cage, and the spring can be pretensioned between the stops.
- Figure 1 shows a top view in a partially schematic form of a tumbler 10, which is arranged on a fixed element (not shown), for example a door stop opposite a movable element, here a pivotable door 12.
- the tumbler 10 comprises a locking bolt 14 which is displaceably mounted in the longitudinal direction L as a movable locking element, which interacts with a locking opening 16 on the door 12 in such a way that it Fig. 1 shown extended locking position causes a lock of the door 12, and in a retracted open position (in Fig. 1 not shown) releases the locking opening 16.
- the tumbler 10 has a drive in the form of an electric motor 18 which, via a gear 20, in the example shown consisting of a drive pinion 22 and a threaded rod 24, feeds a slide 26 as a transmission element and, coupled thereto, feeds the locking bolt 14 in the closing direction or in the opposite opening direction.
- a gear 20 in the example shown consisting of a drive pinion 22 and a threaded rod 24, feeds a slide 26 as a transmission element and, coupled thereto, feeds the locking bolt 14 in the closing direction or in the opposite opening direction.
- the carriage 26 is here as well Fig. 2 can be seen firmly connected to the rack 24 so that it is directly coupled to the motor without play.
- the locking pin 14 is coupled to the slide 26 via a prestressed, spring-buffered coupling 30, which is explained in detail below.
- a first locking stop 32a is formed on the locking bolt 14 in the form of a step, and a second locking stop 32b as a ring at a distance from it.
- a coupling structure comprising a first sleeve-shaped coupling element 34a, a second sleeve-shaped coupling element 34b and a compression spring 40 acting between the coupling elements 34a, 34b is arranged between the closure stops 32a, 32b.
- the coupling elements 34a, 34b are each designed as sleeves around the locking bolt 14. They are displaceable in the longitudinal direction L with respect to the locking bolt 14.
- the coupling elements 34a, 34b are also pressed apart by the compression spring 40 which is also arranged around the locking bolt 14 and acted upon in the direction of the locking stops 32a, 32b.
- the spring 40 is biased between the coupling elements 34a, 34b, so that in the in Fig. 3a shown rest position, in which the coupling elements 34a, 34b have a maximum distance A from each other, the compression spring 40 keeps the coupling 30 under tension.
- the carriage 26 has a cage 28, which is penetrated by the locking bolt 14 and the penetrating portion of which also surrounds the coupling elements 32a, 32b and the compression spring 40. Stops are formed on the inside of the cage 28 in the form of a first drive stop 36a and a second drive stop 36b.
- the coupling elements 34a, 34b are arranged between the drive stops 36a, 36b and are displaceable relative to the slide 26. How from Fig. 3a As can be seen, the cage 28 of the carriage 26 has openings 38a, 38b on both sides in the longitudinal direction L, through which both the locking bolt 14 and the projecting collar of the coupling elements 34a, 34b engage.
- the closure stops 32a, 32b are thus arranged outside the drive stops 36a, 36b.
- the coupling elements 34a, 34b can move in their respective directions up to the stop either on the respective closure stop 32a, 32b or on the respective drive stop 36a, 36b.
- the rest position shown is the coupling between the locking bolt 14 and completely given to the carriage 26.
- the compression spring 40 acts on the coupling elements 34a, 34b in such a way that they each lie on the outside against both the drive stops 36a, 36b and the locking stops 32a, 32b.
- the pretensioning of the spring 40 provides a tight, play-free coupling, so that the locking bolt 14 and the slide 26 move synchronously and rigidly with one another, with the coupling 30 also transmitting forces between the elements insofar as these are below the pretensioning of the Spring 40 lie.
- the locking bolt 14 is blocked when the drive 18, 20 is activated, very high forces can act on the locking bolt 14 and the drive. If the drive 18, 20 acts in the closing direction L on the locking bolt 14 and, for example, the door 12 is not completely closed, so that the locking opening 16 is not overlapping, the locking bolt 14 moves into the blockage when the drive 18, 20 continues to operate. Such a blocking can also lead to high forces when the direction of action is reversed: if the drive 18, 20 causes the locking bolt 14 to move into the unlocked position, but at the same time strong side forces are exerted on the door 12, the locking bolt also locks strong force on the coupling 30.
- the coupling 30 enables the following as regards 3b, 3c is explained, a certain play, ie a relative movement between the carriage 26 and the locking pin 14.
- Fig. 3b shows the coupling 30 under the action of a high force F in the pulling direction of the locking bolt 14, as it could occur, for example, in the event of a locking of the locking bolt 14 in the causes of the movement of the carriage 26 from the locking position into the unlocking position.
- the force F acts on the first coupling element 34a via the cage 28 and its first drive stop 36a.
- the force is transmitted via the compression spring 40 to the second coupling element 34b, which, however, is acted upon by the second closing stop 32b in the opposite direction. If the amount of the forces acting relatively on the elements lies above the pretension of the spring 40, this becomes as in FIG Fig. 3b shown compressed so that the coupling elements 34a, 34b move against each other against the action of the spring 40.
- the distance between the coupling elements decreases by a spring travel compared to the maximum distance A until the coupling elements 34a, 34b touch in extreme cases.
- Fig. 3c shows the coupling 30 in the case of the action of a high force F in the opposite direction, as it could occur, for example, in the case of the locking bolt 14 being blocked when moving from the opening into the locking position.
- the first coupling element 34a separates from the system at the first drive stop 36a and likewise the second coupling element 34b from its system at the second locking stop 32b.
- the coupling elements 34a, 34b move towards one another even with this opposite action and compress the spring 40. This results in a relative displacement of the slide 26 and the locking bolt 14 by a maximum of the length A, so that a decoupling is also made possible here to a small extent.
- a rigid and synchronous connection between the slide 26 and the locking bolt 14 is provided as long as no force acting on the coupling 30 acts on the coupling 30.
- the bias of the spring 40 can be selected so that the in 3b, 3c Shown triggering of the coupling 30, that is, the elements are temporarily decoupled from one another only under forces which would otherwise lead to the destruction of the drive 18, 20.
- the coupling 30 remains compact overall. For example, a maximum spring travel of only 2 mm with a maximum stroke of the locking bolt 14 of 20 mm, that is to say a play of a maximum of 20%, can effectively suffice to avoid destruction.
- the blocking of the locking bolt 14 is determined by a suitable sensor in order to switch off the drive in good time. This can be done, for example, by a current detection on the motor 18 or by position sensors on the locking bolt 14.

Description
Die Erfindung betrifft eine Zuhaltung, d.h. Verschluss- oder Verriegelungsvorrichtung.The invention relates to a tumbler, i.e. Locking or locking device.
Zuhaltungen werden bspw. verwendet in Zugangsschutzeinrichtungen an einem beweglichen, einen Bereich verschließenden Element wie beispielsweise einer Tür, Klappe oder Deckel. Mittels einer Zuhaltung kann ein solches bewegliches Element arretiert, bzw. verriegelt werden.Tumblers are used, for example, in access protection devices on a movable element that closes an area, such as a door, flap or lid. Such a movable element can be locked or locked by means of a tumbler.
Derartige Zugangsschutzeinrichtungen können in vielen Bereichen Verwendung finden, insbesondere in der Automatisierungstechnik. Dort kann bspw. der Zugang zu einer Anlage, wie einem Roboter oder anderer maschineller oder chemischer Anlage durch eine Umgrenzung beschränkt sein, in der eine Tür oder Klappe vorgesehen ist, die bspw. durch Schwenken oder Schieben zu öffnen ist.

There, for example, access to a system, such as a robot or other mechanical or chemical system, can be restricted by a boundary in which a door or flap is provided, which can be opened, for example, by pivoting or sliding.

Es ist Aufgabe der Erfindung, eine Zuhaltung und ein Betriebsverfahren hierfür vorzuschlagen, bei der eine sichere Ver- und Entriegelung ermöglicht und im Fall einer Blockierung eines beweglichen Verschlusselements Beschädigungen vermieden werden.It is the object of the invention to propose a tumbler and an operating method for this, in which a secure locking and unlocking is made possible and damage is avoided in the event of a blocking of a movable closure element.
Die
Diese Aufgabe wird gelöst durch eine Zuhaltung gemäß Anspruch 1 und ein Verfahren zum Betrieb einer Zuhaltung gemäß Anspruch 13. Abhängige Ansprüche beziehen sich auf vorteilhafte Ausführungsformen der Erfindung.This object is achieved by a tumbler according to claim 1 and a method for operating a tumbler according to claim 13. Dependent claims relate to advantageous embodiments of the invention.
Erfindungsgemäß umfasst die Zuhaltung ein in einer Schließrichtung bewegliches Verschlusselement, bspw. einen Verriegelungsbolzen, der in seiner Längsrichtung verschieblich ist in Schließ- bzw. entgegengesetzter Öffnungsrichtung, mindestens zwischen einer Schließstellung, in der ein Teil des Verschlusselements mit einem Aufnahmeelement, bspw. einer Aufnahmeöffnung, zur Bildung einer Verriegelung zusammenwirkt, und einer Öffnungsstellung, in der das Verschlusselement die Verriegelung freigibt.According to the invention, the tumbler comprises a locking element that is movable in a closing direction, for example a locking bolt that is displaceable in its longitudinal direction in the closing or opposite opening direction, at least between a closed position in which a part of the locking element with a receiving element, for example a receiving opening, cooperates to form a lock, and an open position in which the closure element releases the lock.
Erfindungsgemäß umfasst die Zuhaltung einen Antrieb mit einem Übertragungselement zur Bewegung des Verschlusselements. Das Übertragungselement ist über ein Getriebe zur Verschiebung in Längsrichtung mit einem Motor gekoppelt. Bevorzugt sieht der Antrieb einen Motor zum rotatorischen Antrieb vor, der bspw. mittels einer Zahnstange oder Antriebsspindel zur Verschiebung des Übertragungselements in der Schließrichtung gekoppelt ist. Besonders bevorzugt ist die Verwendung eines Elektromotors mit entsprechendem Getriebe.According to the invention, the tumbler comprises a drive with a transmission element for moving the closure element. The transmission element is coupled to a motor via a gear for displacement in the longitudinal direction. The drive preferably provides a motor for the rotary drive, which is coupled, for example, by means of a toothed rack or drive spindle for displacing the transmission element in the closing direction. The use of an electric motor with a corresponding gear is particularly preferred.
Das Übertragungselement ist über eine Kopplung mit dem Verschlusselement bewegungs- bzw. kraftgekoppelt, so dass das Übertragungselement mit dem Verschlusselement in eine erste Bewegungsrichtung parallel zur Schließrichtung und eine zweite, entgegengesetzte Bewegungsrichtung gemeinsam beweglich ist. Bevorzugt handelt es sich bei dieser Bewegung um eine lineare Bewegung, so dass über die Kopplung Übertragungselement und Verschlusselement gemeinsam linear verfahrbar sind.The transmission element is coupled to the closure element in terms of movement or force, so that the transmission element can be moved together with the closure element in a first direction of movement parallel to the closing direction and a second, opposite direction of movement. This movement is preferably a linear movement, so that the transmission element and the closure element can be moved linearly together via the coupling.
Die Kopplung ist erfindungsgemäß so ausgestaltet, dass sie in beiden Bewegungsrichtungen unter Vorspannung federgepuffert ist. Unabhängig davon, ob das Verschlusselement vom Antrieb über das Übertragungselement und die Kopplung in Schließrichtung oder in die entgegengesetzte Öffnungsrichtung verfahren werden soll, wirkt über die Kopplung eine Federung, so dass bei einer Blockierung des Verschlusselements eine Bewegung des Übertragungselements in einer der Bewegungsrichtungen gegen eine Federkraft um einen Federweg möglich ist. Dabei steht die Kopplung unter Vorspannung, so dass die Auslenkung um den Federweg erst bei Überwindung der Vorspannung möglich ist.The coupling is designed according to the invention so that it is spring-biased in both directions of movement under prestress. Regardless of whether the closure element is to be moved by the drive via the transmission element and the coupling in the closing direction or in the opposite opening direction, a spring acts via the coupling, so that when the closure element is blocked, the transmission element moves in one of the directions of movement against a spring force around a suspension travel is possible. The coupling is pretensioned so that the deflection around the spring travel is only possible when the pretension is overcome.
Durch die in beiden Bewegungsrichtungen federgepufferte Kopplung wird im Fall der Blockierung des Verschlusselements eine direkte mechanische Rückwirkung auf den Antrieb oder zwischengeschaltete Elemente, bspw. ein Getriebe, vermieden. Gleich ob das Verschlusselement bei einer Bewegung in Schließrichtung oder in die entgegengesetzte Öffnungsrichtung blockiert wird, erfolgt hierdurch keine unmittelbare Blockierung des Übertragungselements und somit des Antriebs, sondern eine mindestens kurze Bewegung um den Federweg gegen die genannte Federkraft. Besonders vorteilhaft ist dabei die Vorspannung, durch die eine besonders straffe Kopplung realisiert werden kann, so dass tatsächlich erst im Fall einer Blockierung mit den dabei auftretenden erheblichen Kräften die Auslenkung um den Federweg erfolgt, nämlich bei einer so hohen einwirkenden Kraft, dass die Vorspannung der Kopplung überwunden wird.Due to the spring-buffered coupling in both directions of movement, a direct mechanical reaction on the drive or intermediate elements, for example a transmission, is avoided in the event of the blocking element being blocked. No matter whether the closure element is blocked during a movement in the closing direction or in the opposite opening direction, this does not result in an immediate blocking of the transmission element and thus of the drive, but rather an at least short movement about the spring travel against the spring force mentioned. The pretension is particularly advantageous, as a result of which a particularly tight coupling can be achieved, so that the deflection around the spring travel actually takes place only in the event of a blockage with the considerable forces that occur, namely with a force acting so high that the pretensioning of the Coupling is overcome.
Durch die erfindungsgemäße Lösung wird so die Gefahr von Beschädigungen bei Blockierung des Verschlusselements deutlich herabgesetzt. Sehr hohe einwirkende Kraftstöße wirken dann nicht unmittelbar auf das Übertragungselement und den Antrieb, sondern führen unter Überwindung der Vorspannung zur Auslösung der Kopplung mit einer Bewegung um den Federweg. Gleichzeitig kann durch die Vorspannung das Auslösen der Kopplung auf die tatsächlich einwirkenden hohen Kräfte im Fall einer Blockierung beschränkt werden, während die Kopplung durch geeignete Auswahl der Vorspannung so einstellbar ist, dass die sich im Normalbetrieb starr verhält.The solution according to the invention thus significantly reduces the risk of damage when the closure element is blocked. Very high impacts do not then act directly on the transmission element and the drive, but lead to the coupling being triggered with a movement around the spring deflection while overcoming the preload. At the same time, the pretensioning can limit the triggering of the coupling to the actually acting high forces in the event of a blockage, while the coupling can be adjusted by suitable selection of the pretensioning so that it behaves rigidly in normal operation.
Bevorzugt erfolgt die Bewegung des Verschlusselements dabei trotz der federgepufferten Kopplung weitgehend synchron zur Bewegung des Übertragungselements. Zur Vermeidung von Beschädigungen kann es durchaus ausreichen, wenn lediglich der unmittelbare, durch eine Blockierung des Verschlusselements erfolgende Stoß abgepuffert wird, ohne dass wie bei einigen Lösungen des Standes der Technik eine weitgehende Entkopplung der Bewegung des Verschlusselements und des Übertragungselements erfolgt. Daher kann bevorzugt der in der Kopplung vorgesehene maximale Federweg auf einen im Vergleich zur gesamten Bewegung des Verschlusselements geringen Betrag beschränkt werden.In spite of the spring-buffered coupling, the movement of the closure element is preferably largely synchronized with the movement of the transmission element. To avoid damage, it may be sufficient if only the immediate impact caused by a blocking of the closure element is buffered without, as with some solutions of the prior art, extensive decoupling of the movement of the closure element and the transmission element. Therefore, the maximum spring travel provided in the coupling can preferably be limited to a small amount compared to the entire movement of the closure element.
Bevorzugt ist bspw. das Verschlusselement in Schließrichtung um einen maximalen Verfahrweg verfahrbar, der durch die Konstruktion und Ausgestaltung des Antriebs und des Übertragungselements begrenzt sein kann, ebenso aber auch durch eine entsprechende Ansteuerung des Antriebs. Der maximale Verfahrweg kann je nach Verwendung der Zuhaltung bspw. 5 - 50 mm, in einigen Anwendungen bspw. 10 - 30 mm betragen. Der maximale Federweg der Kopplung kann bspw. konstruktiv begrenzt sein, z.B. durch den Abstand zweier Anschläge. Der maximale Federweg der Kopplung kann dabei bevorzugt gering gewählt werden, bspw. weniger als 50% des maximalen Verfahrwegs betragen. Bevorzugt für eine möglichst synchrone Kopplung ist eine noch engere Begrenzung des maximalen Federwegs auf bspw. 25% oder weniger des maximalen Verfahrwegs, besonders bevorzugt 10% oder weniger. So kann der maximale Federweg bspw. auf wenige mm beschränkt sein, wobei dennoch das Ziel erreicht wird, Beschädigungen im Fall einer Blockierung zu verhindern. Gleichzeitig kann durch die Begrenzung des maximalen Federwegs ein sehr kompakter Aufbau der Kopplung erzielt werden.Preferably, for example, the closure element can be moved in the closing direction by a maximum travel path, which can be limited by the design and configuration of the drive and the transmission element, but also by correspondingly controlling the drive. Depending on the use of the guard locking, the maximum travel distance can be, for example, 5 - 50 mm, in some applications, for example, 10 - 30 mm. The maximum spring travel of the coupling can be limited, for example by design, for example by the distance between two Attacks. The maximum travel of the coupling can preferably be chosen to be small, for example less than 50% of the maximum travel. An even narrower limitation of the maximum spring travel to, for example, 25% or less of the maximum travel path, particularly preferably 10% or less, is preferred for a coupling that is as synchronous as possible. For example, the maximum spring travel can be limited to a few mm, while still achieving the goal of preventing damage in the event of a blockage. At the same time, a very compact coupling design can be achieved by limiting the maximum spring travel.
Gemäß einer bevorzugten Ausführungsform der Erfindung ist zur Realisierung der Kopplung mindestens ein Kopplungselement vorgesehen, das sowohl gegenüber dem Übertragungselement als auch gegenüber dem Verschlusselement in mindestens eine der Bewegungsrichtungen beweglich, insbesondere bevorzugt verschieblich ist. Am Übertragungselement ist bevorzugt mindestens ein Antriebsanschlag und am Verschlusselement mindestens ein Verschlussanschlag ausgebildet, wobei durch Anlage des Kopplungselements gegen diese Anschläge die Bewegung begrenzt wird. Weiter ist bevorzugt mindestens eine Feder vorgesehen, um das Kopplungselement in Richtung dieser Anschläge zu beaufschlagen.According to a preferred embodiment of the invention, at least one coupling element is provided for realizing the coupling, said coupling element being movable, in particular preferably displaceable, both in relation to the transmission element and in relation to the closure element in at least one of the movement directions. At least one drive stop is preferably formed on the transmission element and at least one lock stop is formed on the closure element, the movement being limited by abutment of the coupling element against these stops. Furthermore, at least one spring is preferably provided in order to act on the coupling element in the direction of these stops.
Besonders bevorzugt ist es dabei, dass mindestens ein erstes und ein zweites Kopplungselement vorgesehen sind, die beide sowohl gegenüber dem Übertragungselement und gegenüber dem Verschlusselement beweglich, bevorzugt verschieblich, sind und dass eine Druckfeder zwischen den Kopplungselementen wirkt.It is particularly preferred that at least one first and one second coupling element are provided, both of which are movable, preferably displaceable, both with respect to the transmission element and with respect to the closure element, and that a compression spring acts between the coupling elements.
Die Kopplung mittels eines zwischengeschalteten Kopplungselements, auf das eine Feder wirkt, ermöglicht die gewünschte Entkopplung zwischen dem Verschluss- und Übertragungselement. Die Verwendung von zwei Kopplungselementen ermöglicht bei einfachem Aufbau insbesondere die beidseitige Entkopplung. Während mehrere Federn zur Erzeugung der Federkraft verwendet werden können, wird die Konstruktion durch die Verwendung einer einzelnen Druckfeder zwischen den Kopplungselementen deutlich vereinfacht.The coupling by means of an interposed coupling element, on which a spring acts, enables the desired decoupling between the closure and transmission element. The use of two coupling elements enables decoupling on both sides with a simple construction. While multiple springs can be used to generate the spring force, the construction is significantly simplified by using a single compression spring between the coupling elements.
Bevorzugt soll eine solche Druckfeder innerhalb der Kopplung in beiden Bewegungsrichtungen wirken und so die gewünschte Federkraft bereitstellen, unabhängig davon, ob sie in Schließ- oder Öffnungsrichtung wirkt. Weiter bevorzugt kann die Druckfeder zur Erzeugung der gewünschten Vorspannung entsprechend vorgespannt sein, weiter bevorzugt zwischen dem ersten und zweiten Kopplungselement. So kann die gewünschte Übertragungscharakteristik der Kopplung mit einer sehr einfachen mechanischen Konstruktion erzielt werden.Such a compression spring should preferably act within the coupling in both directions of movement and thus provide the desired spring force, regardless of whether it acts in the closing or opening direction. The compression spring can more preferably be used for production be biased according to the desired bias, more preferably between the first and second coupling elements. In this way, the desired transmission characteristics of the coupling can be achieved with a very simple mechanical construction.
In einer besonders bevorzugten Ausführung sind am Verschlusselement mindestens ein erster und ein zweiter Verschlussanschlag vorgesehen, jeweils für ein erstes und ein zweites Kopplungselement. Am Übertragungselement können ebenfalls mindestens zwei Anschläge vorgesehen sein, ein erster Antriebsanschlag für das erste Kopplungselement und ein zweiter Antriebsanschlag für das zweite Kopplungselement. Die Kopplungselemente sind bevorzugt angeordnet zwischen den Anschlägen, nämlich zwischen dem ersten Verschlussanschlag und dem ersten Antriebsanschlag auf der einen Seite und dem zweiten Verschlussanschlag und dem zweiten Antriebsanschlag auf der gegenüberliegenden Seite. Mit dieser einfachen Konstruktion kann eine in beiden Richtungen wirkende Kopplung aufgebaut sein.In a particularly preferred embodiment, at least a first and a second closure stop are provided on the closure element, each for a first and a second coupling element. At least two stops can also be provided on the transmission element, a first drive stop for the first coupling element and a second drive stop for the second coupling element. The coupling elements are preferably arranged between the stops, namely between the first closure stop and the first drive stop on one side and the second closure stop and the second drive stop on the opposite side. With this simple construction, a coupling acting in both directions can be established.
Dabei ist insbesondere bevorzugt, dass zwischen den Kopplungselementen eine Druckfeder vorgesehen ist, die weiter bevorzugt vorgespannt ist, um das erste Kopplungselement in Richtung des ersten Verschlussanschlags und des ersten Antriebsanschlags und das zweite Kopplungselement in Richtung des zweiten Verschlussanschlags und des zweiten Antriebsanschlags zu beaufschlagen. Durch die Anschläge wird so die gewünschte Vorspannung in beiden Richtungen ermöglicht, während durch die Kopplungselemente, die durch die Feder beaufschlagt sind, die gewünschte Entkopplung gewährleistet wird.It is particularly preferred that a compression spring is provided between the coupling elements, which is further preferably biased to act on the first coupling element in the direction of the first closure stop and the first drive stop and the second coupling element in the direction of the second closure stop and the second drive stop. The stops enable the desired pretension in both directions, while the desired decoupling is ensured by the coupling elements which are acted upon by the spring.
Bevorzugt ist das Verschlusselement als Bolzen ausgebildet, bspw. mit rundem Querschnitt. Die Kopplungselemente können so ausgebildet sein, dass sie das Verschlusselement umgreifen, bspw. als Hülsen. Auch das Übertragungselement kann das Verschlusselement umgreifend ausgebildet sein, bspw. als Käfig. Besonders bevorzugt ist dann, dass innerhalb des Käfigs mindestens eine Feder und mindestens ein, bevorzugt zwei Kopplungselemente angeordnet sind. An dem Käfig können Anschläge für die Kopplungselemente vorgesehen sein, und die Feder kann zwischen den Anschlägen vorgespannt sein.The closure element is preferably designed as a bolt, for example with a round cross section. The coupling elements can be designed such that they encompass the closure element, for example as sleeves. The transmission element can also be designed to encompass the closure element, for example as a cage. It is then particularly preferred that at least one spring and at least one, preferably two, coupling elements are arranged within the cage. Stops for the coupling elements can be provided on the cage, and the spring can be pretensioned between the stops.

Durch die beidseitig wirkende, federgepufferte und vorgespannte Kopplung 30 wird in geringem Maß Spiel zwischen der Bewegung des Schließbolzens 14 und des Schlittens 26 ermöglicht, d.h. eine Relativbewegung zwischen diesen beiden Teilen. Wie nachfolgend erläutert wird, ist die Relativbewegung aufgrund der Vorspannung nur bei relativ starker Krafteinwirkung möglich, insbesondere bei aktivem Antrieb durch den Motor 18 und das Getriebe 20 bei gleichzeitiger Blockierung des Schließbolzens 14.Due to the double-acting, spring-buffered and

Die Koppelelemente 34a, 34b sind jeweils als Hülsen um den Schließbolzen 14 herum ausgebildet. Sie sind gegenüber dem Schließbolzen 14 in Längsrichtung L verschieblich. Durch die ebenfalls um den Schließbolzen 14 herum angeordnete Druckfeder 40 werden die Koppelemente 34a, 34b auseinander gedrückt und in Richtung der Verschlussanschläge 32a, 32b beaufschlagt. Dabei ist die Feder 40 zwischen den Koppelelementen 34a, 34b vorgespannt, so dass in der in
Der Schlitten 26 weist einen Käfig 28 auf, der vom Schließbolzen 14 durchdrungen wird und dessen durchdringenden Abschnitt ebenso wie die Kopplungselemente 32a, 32b und die Druckfeder 40 umschließt. An den Innenseiten des Käfigs 28 sind dabei Anschläge gebildet in Form eines ersten Antriebsanschlags 36a und eines zweiten Antriebsanschlags 36b.The
Die Koppelelemente 34a, 34b sind zwischen den Antriebsanschlägen 36a, 36b angeordnet und gegenüber dem Schlitten 26 verschiebbar. Wie aus

Im Fall der Blockierung des Schließbolzens 14 bei Aktivierung des Antriebs 18, 20 können sehr hohe Kräfte auf den Schließbolzen 14 und den Antrieb wirken. Wirkt der Antrieb 18, 20 in Schließrichtung L auf den Schließbolzen 14 und ist bspw. die Tür 12 nicht vollständig geschlossen, so dass sich die Verriegelungsöffnung 16 nicht in Überdeckung befindet, so fährt der Schließbolzen 14 bei weiterwirkendem Antrieb 18, 20 in die Blockierung. Auch bei umgekehrter Wirkrichtung kann eine solche Blockierung zu hohen Kräften führen: Bewirkt der Antrieb 18, 20 das Verfahren des Schließbolzens 14 in die Entriegelungsstellung, während aber gleichzeitig starke Seitenkräfte auf die Tür 12 ausgeübt werden, kommt es aufgrund der Blockierung des Schließbolzens ebenfalls zu einer starken Krafteinwirkung auf die Kopplung 30.If the locking
Zur Vermeidung von Beschädigungen, insbesondere am Antrieb 18, 20, ermöglicht die Kopplung 30 wie nachfolgend im Hinblick auf
Durch das Zusammendrücken der Feder 40 und die Bewegung der Koppelelemente 34a, 34b wird so eine geringfügige Relativbewegung zwischen dem Schlitten 26 und dem Schließbolzen 14 ermöglicht, die maximal dem ursprünglichen Abstand A der Koppelelemente 34a, 34b entspricht. So kann bei Einwirkung sehr hoher Kräfte eine vollständige Blockierung des Schlittens 26 vermieden werden.The compression of the
Dabei ist im Normalbetrieb, solange auf die Kopplung 30 keine die Vorspannung der Feder 40 übersteigende Kraft wirkt, eine starre und synchrone Verbindung zwischen dem Schlitten 26 und dem Schließbolzen 14 gegeben. Die Vorspannung der Feder 40 kann so gewählt werden, dass die in
Der Erfolg einer geringfügigen Entkopplung kann dabei schon bei recht geringen Abständen A, d.h. geringen maximalen Federwegen erreicht werden. So bleibt die Kopplung 30 wie dargestellt insgesamt kompakt. Beispielsweise kann bereits ein maximaler Federweg von lediglich 2mm bei einem Maximalhub des Schließbolzens 14 von 20mm, also ein Spiel von maximal 20%, effektiv ausreichen, um Zerstörungen zu vermeiden.The success of a slight decoupling can be achieved even at very small distances A, ie small maximum spring travel. As shown, the
In jedem Fall ist es zu bevorzugen, wenn die Blockierung des Schließbolzens 14 durch einen geeigneten Sensor ermittelt wird, um den Antrieb rechtzeitig abzuschalten. Dies kann bspw. durch eine Stromdetektion am Motor 18 oder durch Positionssensoren am Schließbolzen 14 erfolgen.In any case, it is preferable if the blocking of the locking
