- an escape door has a door leaf 10 with an electrically controlled door lock device 11, to which a lock 9 in the door leaf 10, a handle 12 formed as a latch and a lock fitting 13 which are arranged on the inside of the door leaf 10 in the escape direction.
- An extended in a door frame 5 locking bolt is denoted by 6.
- the door lock device 11 further includes a in the Fig. 2 to 5 illustrated, operating according to the closed-circuit principle unlocking device 7 or 7 ', which is functionally arranged between the handle 12 and the lock 9 within a lock fitting 13.
- the partial section illustrates that in the door leaf 10 behind the lock fitting 13 in a lock case 16 ( Fig. 2 ) arranged lock 9, which is actuated via the handle 12.
- the unlocking device 7, 7 ' is hidden as a separate unit behind the lock fitting 13.
- a lock cylinder inserted into the lock 9 is designated 3.
- the lock 9 may be formed as a conventional escape door lock, which can be opened from the outside only with a key. Since the unlocking device 7 or 7 'is preceded on the inside of the lock 9, wherein the power flow is electrically controlled by the inside handle 12 on the lock 9, the lock 9 can also as a per se known security lock with a split follower and one with working current controlled coupling, which allows access from the outside.
- the door can therefore also - as exemplified - be provided with a multi-point lock, which consists in that the lock 9 is connected via two linkage 8 with two lock boxes 4, each having a further locking latch 6 '. Instead of a locking bolt or more locking bolts also traps may be present.
- an emergency button 14 and a key switch 15 for the authorized arming of the door lock device 11 are arranged on the wall side.
- the door lock device 11 In a home position in which the door is closed, the door lock device 11 is locked electromechanically, so that a depression of the handle 12 does not lead to Freigebe the door lock device 11 and the door can not be opened. Only when the emergency button 14 has been pressed or the key switch 15 has been operated by an authorized operator, the lock is released and the lock 9 and the door are released for opening.
- FIG. 2, 3rd and 4 illustrate a first lock-unlocking device 7 in the view of Fig. 1 , wherein the lock fitting 13 and the handle 12 are removed, so that a plan view of the side wall of a door lock box 16 can be seen.
- the unlocking device 7 may be formed as an independently mountable unit which is disposed within the lock fitting or it may be formed as an integral part of the lock fitting 13.
- a trained as a square two-part mandrel 17 is led out of the lock case 16.
- the handle is attached to the protruding from the plane of free end of the mandrel 17, but in Fig. 2, 3rd and 4 not shown to keep the drawing clear.
- the mandrel 17 has a handle-side mandrel portion 17a and a lock-side mandrel portion 17b, which are shown here for ease of distinction with different sized rectangular cross-sections.
- the lock-side mandrel portion 17b is mounted in the lock case 16 in a known manner in a conventional follower or in the case of a safety lock with a conventional split pusher nut (not shown) via which the lock bolts 6, 6 '(FIGS. Fig. 1 ) can be closed in a known manner by a rotation about the longitudinal axis to open the door.
- the two mandrel sections 17a, 17b are mounted at their facing ends in a two-part further presser foot 18, wherein the lock-side mandrel section 17b comes to rest in a lock-side nut 18a and the handle-side mandrel section 17a in a handle-side nut 18a.
- the lock-side and handle-side nuts 18a, 18b are again shown differently sized for better distinction. Due to the division of the mandrel 17 and the follower 18, the direct flow of force from the handle 12 (FIG. Fig. 1 ) is interrupted on the lock-side mandrel portion 17b and thus on the lock 9.
- the handle 12 is followed by a mechanical energy store 21 which stores a force applied to the handle 12.
- the energy store 21 is in operative connection with the lock-side mandrel section 17b in such a way that the stored force can be converted into a torque which acts on the lock-side mandrel section 17b.
- the torque generates a rotation of the lock-side mandrel section 17b and thus a closing back of the lock bolts 6, 6 '(FIG. Fig. 1 ).
- a handle-side and a lock-side gear 20a, 20b is arranged in each case, which in the present example as a handle side Adjusting lever 19a or formed as a lock-side lever 19b and rotatably connected to the respective mandrel portions 17a, 17b are connected.
- the two adjusting levers 19a, 19b are connected via the energy accumulator 21.
- the energy storage 21 is designed as a spring store, here as a tension spring 21a.

- an electromagnetic lock 22 with a solenoid 23 and an armature 24 is provided, which forms a two-armed pawl together with a locking lever 25.
- the lock 22 acts as a holding brake for the lock-side lever 19b. It controls the lock-side lever 19b as a turnstile. It hinders him in a basic position, which in Fig. 1 shown as well as in willful, unauthorized operation, as in Fig. 3 shown at a deflection. If the locking bolts 6, 6 'may be closed in an emergency or authorized lock operation, the lock 22 releases the lock-side lever 19 b, which in a release position according to Fig. 4 is illustrated.
- the electrically controlled lock 22 of the door lock device 11 is thus in the power flow between the handle 12 and the lock side mandrel portion 17b.
- the barrier 22 operates in the case of an escape door on the closed-circuit principle, ie when energized, the armature 24 is energized and the locking lever 25 is in the blocking position. This quiescent position takes the lock in FIGS. 2 and 3 one.
- the handle 12 If the handle 12 is depressed in a clockwise direction, it takes along the associated handling-side adjusting lever 19a. Since the lock-side lever 19b is held by the lock lever 25 in its position, the tension spring 21a is stretched and the movement takes place against the force of the tension spring 21a. As Fig. 3 In this position, the sides of the handle-side are illustrated Mandrel portion 17a and the lock side mandrel portion 17b angularly offset. The tension spring 21a stores the applied force as long as the handle 12 is pressed. If the lock 22 is not released in this situation, the tension spring 21a acts as a return device for the handle-side adjusting lever 19a as soon as the handle 12 is released.
- the tension spring 21a retracts the handle 12 after releasing with the stored force in the basic position, the tension spring 21a is relieved.
- Such operation of the handle 12 with the lock 22 locked is typical of misuse of the door lock device 11, which may also be referred to as sabotage.
- the tension spring 21a also has the task to oppose the depression of the handle 12 an elastic resistance to prevent hard impacts of the handle 12 on the door lock device 11, which could lead to damage.
- the lock 22 is released by closing the current by depressing the emergency button 14 (FIG. Fig. 1 ) is turned off, the armature 24 is released and pivoted together with the locking lever 25 by a tension spring 37 in a clockwise direction. wherein the lock-side lever 19b is released.
- the force stored in the mainspring 21a then acts on the lock-side lever 19b and lets him follow the handle-side lever 19a in a clockwise direction until it arrives at the stop 26 in the Feigabeposition, the in Fig. 4 is shown.
- the stored force of the tension spring 21a generates a torque on the lock side mandrel portion 17b via the lock side lever 19b, which causes the lock side mandrel portion 17b to rotate clockwise. With this rotation, the locking bolts 6, 6 'of the lock 9 ( Fig. 1 ) and the door can be opened.
- an unlocking device 7 ' which may preferably be arranged within a lock fitting, the adhesion of the handle 12 to the lock side mandrel portion 17b on the handle-side mandrel portion 17a, a driving handle-side gear 20a ', a force storage 21', which is formed as a package of two parallel compression springs 21b , as well as an outgoing lock-side gear 20b '.
- the handling-side gear 20a ' consists of a handle-side pusher 18a', which is provided with a handle-side cam 28a, and a linearly displaceable handle-side push rod 34a which engages via a handle-side groove 30a with the handle-side cam 28a.
- the handling-side push rod 34a is connected to a tensioning device of the force accumulator 21 '. It consists of an input side block 31 and an output side block 36, between which the compression springs 21b are arranged.

- the output-side block 36 is slidably guided on the two Federspannstangen 32.
- the connecting web 33 is firmly connected to the handling side push rod 34 a. If the connecting web 33 is moved away from the output-side block 36, the input-side block 31 is moved toward the output-side block 36 against the spring force.
- the lock-side gear 20b ' is composed of a linearly movable lock-side push rod 34b provided with a lock-side groove 30b, a lock-side nut 18b' having a lock-side cam 28b engaged with the lock-side groove 30b in the lock-side push rod 34b , and a rocker 35 between the lock-side push rod 34b and the energy storage 21 '.
- the output side block 36 is supported against a first arm 35b of the rocker 35.
- the second arm 35c is engaged via a pin 35d with a slot 29 of the lock-side push rod 34b.

- an electromechanical lock 22 'in such a manner that the lock side push rod 34b is locked in a home position.
- the lock 22 ' acts as a holding brake, wherein the locking lever 25' holds the lock-side push rod 34b at rest in the home position. In the basic position of the lock-side part of the device is thus not burdened with a bias voltage.
- the push rod can move depending on the stored force in the memory 21 force upwards.
- the handle-side push rod 34a When the handle 12 is then released, the handle-side push rod 34a is pushed up by the handle-side cam 30a, the input-side block 31 moves upwardly together with the link 33, the compression springs 21b are relieved, they relax, and the output-side block 36 as well as the input-side block 31 assume the basic position, whereby the handle 12 is returned in its normal position counterclockwise.
- the energy storage 21 'thus acts as a restoring device for the handle 12.
- the lock-side push rod 34b is moved counterclockwise over the lock-side nut 18b down to the home position via a rotation of the lock-side mandrel 17b.
- the rotation of the lock-side mandrel 17b counterclockwise takes place by a lock-side spring (not shown), as is conventionally present in a lock for returning the handle 12.

Description
Die Erfindung betrifft eine Tür mit Türblatt und Türschlossvorrichtung, beispielsweise eine Tür mit Fluchttürfunktion, mit einer elektromechanischen Sperre für die Entriegelung, mit einer Handhabe zur Betätigung des Schlosses, und mit einem Dorn zum Zurückschließen eines Riegels mittels einer Drehbewegung sowie ein Verfahren zum Öffnen einer Türschlossvorrichtung. Die Erfindung betrifft ferner einen Dorn und einen Beschlag für eine derartige Türschlossvorrichtung sowie die Verwendung eines Kraftspeichers zum Erzeugen eines Drehmoments an einem Dorn einer Türschlossvorrichtung.The invention relates to a door with door leaf and door lock device, such as a door with escape door function, with an electromechanical lock for unlocking, with a handle for actuating the lock, and with a mandrel for closing a latch by means of a rotary movement and a method for opening a door lock device , The invention further relates to a mandrel and a fitting for such a door lock device and the use of an energy accumulator for generating a torque on a mandrel of a door lock device.
Es sind verschiedene Ausführungen von gattungsgemäßen Schlossvorrichtungen bekannt, die eine elektromechanische Sperre für die Entriegelung aufweisen, beispielsweise aus
Insbesondere bei Türen in Fluchttüranlagen kommt es darauf an, dass sie in Fluchtrichtung von jedermann auch bei Stromausfall leicht geöffnet werden können. Schlösser in Notausgangsanlagen arbeiten daher nach dem Ruhestrom-Prinzip, d.h., sie sind bei Bestromung gesperrt und werden in stromlosem Zustand freigegeben. Bei Fluchttüren soll andererseits von außen kein unautorisiertes Öffnen möglich sein. Bisher konnten bei Fluchttüren zwar Sicherheitsschlösser eingesetzt werden, um den unautorisierten Zugang von außen zu erschweren. Dagegen war der Einsatz von einbruchsicheren Schlössern bei Fluchttüren ausgeschlossen, weil sie auf dem Arbeitsstrom-Prinzip beruhen, d.h. bei Stromausfall wird ein Öffnen der Tür verhindert. Fluchttüren sind ferner gegen Vandalismus dadurch geschützt, dass die Handhaben mit einer Vorspannung beaufschlagt sind, welche beim Betätigen einen vorgegebenen Widerstand entgegen setzt, der harte Schläge mit der Handhabe abschwächt, die andernfalls auf das Innere des Schlosses wirken und Beschädigungen herbeiführen könnten.Especially with doors in escape door systems, it is important that they can be easily opened in the escape direction by anyone, even in the event of a power failure. Locks in emergency exit systems therefore operate according to the quiescent current principle, ie, they are blocked when energized and are released in a de-energized state. On escape doors, on the other hand, no unauthorized opening should be possible from the outside. So far, security locks could be used in escape doors to make the unauthorized access from the outside more difficult. On the other hand, the use of burglar-proof locks on escape doors was excluded, because they are based on the working current principle, ie in the event of a power failure, the door is prevented from opening. Escape doors are also protected against vandalism by the fact that the Handles are subjected to a bias, which counteracts a predetermined resistance during actuation, which weakens hard knocks with the handle, which could otherwise act on the interior of the lock and could cause damage.
Der Erfindung liegt die Aufgabe zugrunde, eine Tür mit Türschlossvorrichtung sowie ein Verfahren der eingangs genannten Art anzugeben, die auch unter Vorlast ein zuverlässiges Öffnen gewährleisten, und gleichzeitig eine Manipulation der Handhabe zuverlässig verhindern.The invention has for its object to provide a door with door lock device and a method of the type mentioned above, which ensure reliable opening even under preload, while reliably preventing manipulation of the handle.
Diese Aufgabe wird vorrichtungsmäßig dadurch gelöst, dass der Handhabe ein mechanischer Kraftspeicher nachgeschaltet ist, welcher eine auf die Handhabe aufgebrachte Kraft speichert, dass der Kraftspeicher ausgangsseitig mit dem Dorn in der Weise wirkverbunden ist, dass die gespeicherte Kraft in ein auf den Dorn wirkendes Drehmoment gewandelt wird, und dass die Sperre dem Kraftspeicher nachgeschaltet ist. Verfahrensmäßig wird die Aufgabe dadurch gelöst, dass der Kraftfluss von der Handhabe mittelbar über einen Kraftspeicher auf den Dorn geführt wird, dass die gespeicherte Kraft zum Drehen des Dorns verwendet wird, und dass die gespeicherte Kraft in Abhängigkeit von der Sperre verwendet wird. Als Handhabe kann jedes mit der Hand bedienbare Bedienelement verwendet werden, das die Tür mechanisch freigibt. Es kann sich um einen Drücker, eine Druckstange, eine Griffstange oder ähnliches handeln.This object is achieved by the device in that the handle is followed by a mechanical energy storage, which stores a force applied to the handle force, that the energy storage output side is operatively connected to the mandrel in such a way that the stored force is converted into a torque acting on the mandrel is, and that the lock is downstream of the energy storage. The method achieves this object by virtue of the fact that the force flow from the handle is guided indirectly via a force store onto the mandrel, that the stored force is used to rotate the mandrel, and that the stored force is used as a function of the lock. As a handle, each hand-operable control can be used, which releases the door mechanically. It may be a pusher, a push rod, a handlebar or the like.
Bezüglich des Schlossbeschlags wird die Aufgabe mit einer geteilten Drückernuss und einem Federspeicher gelöst, der mit einem handhabeseitigen Teil der Drückernuss in der Weise wirkverbunden ist, dass mit einer Drehbewegung des Drückerteils der Federspeicher gespannt wird, und der mit dem anderen, schlossseitigen Teil der Drückernuss in der Weise wirkverbunden ist, dass er vom Federspeicher beaufschlagt wird, wenn die Sperre gelöst ist. Als Schlossbeschlag, der auch als Türbeschlag bezeichnet werden kann, wird ein auf ein Türblatt montierbares schildförmiges Bauteil bezeichnet, das an der türzugewandten Unterseite einen Hohlraum aufweisen kann, und an welchem eine Handhabe montiert werden kann. Sie weisen eine Öffnung zur Durchführung eines Dorns auf. Besonders vorteilhaft ist es, den Schlossbeschlag, die geteilte Drückernuss, den Kraftspeicher und die Sperre als separat montierbare Montageeinheit auszuführen. Mit dem Dorn wird die Aufgabe dadurch gelöst, dass er in zwei Abschnitte geteilt ist, zwischen welchen ein Kraftspeicher angeordnet ist.With respect to the lock fitting, the problem is solved with a split pusher and a spring accumulator, which is operatively connected to a handle-side part of the follower in such a way that is clamped with a rotary movement of the pusher of the spring accumulator, and with the other, the lock-side part of the follower in the way is operatively connected, that it is acted upon by the spring accumulator when the lock is released. As a lock fitting, which can also be referred to as a door fitting, a mountable on a door leaf sign-shaped component is referred to, which may have a cavity on the door-facing bottom, and on which a handle can be mounted. They have an opening for the implementation of a mandrel. It is particularly advantageous, the lock fitting, the split handle nut, the Force memory and the lock as a separately mountable mounting unit. With the mandrel, the object is achieved in that it is divided into two sections, between which a force storage device is arranged.
Die Erfindung hat den Vorteil, dass die zur Beaufschlagung des Schlosses erforderliche Kraft über den Kraftspeicher so eingestellt werden kann, dass auch unter Vorlast keine Selbsthemmung eintreten kann. Dadurch, dass die Handhabe gegen die elastische Vorspannung des Federspeichers bewegt wird, ist auch ein guter Schutz gegen Vandalismus gegeben. Da die Sperre innenseitig angeordnet ist, ist es unabhängig davon auch möglich, das Schloss außenseitig mit einem elektromechanischen Schloss nach dem Arbeitsstromprinzip einbruchsicher auszubilden. Die Erfindung kann gleichermaßen bei einem Einsteckschloss und bei einem Aufschraubschloss eingesetzt werden.The invention has the advantage that the force required to act on the lock can be adjusted via the energy accumulator so that no self-locking can occur even under preload. The fact that the handle is moved against the elastic bias of the spring accumulator, there is also a good protection against vandalism. Since the lock is arranged on the inside, it is also possible independently to form the lock on the outside with an electromechanical lock according to the working current principle burglar resistant. The invention can equally be used in a mortise lock and in a screw-on lock.
Eine bevorzugte Weiterbildung der Erfindung besteht darin, dass die Sperre als Drehsperre ausgebildet ist, die auf die Drückernuss wirkt. Grundsätzlich kann die Sperre nahe an der Drückernuss oder innerhalb des Türbeschlags oder an jeder anderen Stelle entlang des Dorns angeordnet sein, so dass die Türschlossvorrichtung in vielfältigen Bauformen ausgeführt werden kann und ein Nachrüsten von herkömmlichen Schlössern möglich ist. Insbesondere ist es möglich, die geteilte Drückernuss zusammen mit dem Kraftspeicher und der Sperre innerhalb eines Schlossgehäuses anzuordnen oder außerhalb des Schlossgehäuses aber innerhalb eines Türblatts. Es ist auch eine Anordnung zwischen Türblatt und Schlossbeschlag möglich oder vollständig innerhalb eines Schlossbeschlags. Die Anordnung kann bevorzugt als separat montierbare Einheit ausgeführt sein, die ergänzend zu herkömmlichen Schlössern eingebaut wird.A preferred embodiment of the invention is that the lock is designed as a turnstile, which acts on the follower. In principle, the lock can be arranged close to the follower or within the door fitting or at any other location along the mandrel, so that the door lock device can be executed in a variety of designs and retrofitting of conventional locks is possible. In particular, it is possible to arrange the split pusher nut together with the energy accumulator and the lock within a lock housing or outside of the lock housing but within a door leaf. It is also an arrangement between the door leaf and lock fitting possible or completely within a lock fitting. The arrangement may preferably be designed as a separately mountable unit, which is installed in addition to conventional locks.
Alternativ zu der Türschlossvorrichtung, bei welcher der Kraftspeicher als Rückstelleinrichtung für die Handhabe ausgebildet ist, wobei die gespeicherte Kraft wieder abgegeben wird, ist es möglich, den Kraftspeicher so auszuführen, dass er nach einer Kraftbeaufschlagung die gespeicherte Kraft nicht abgibt, wenn die Handhabe in ihre Grundstellung zurückgeführt wird. Die gespeicherte Kraft wird dann umgehend abgegeben, sobald die Sperre gelöst wird, ohne dass die Handhabe betätigt werden muss.As an alternative to the door lock device in which the energy accumulator is designed as a return device for the handle, wherein the stored power is released again, it is possible to perform the energy storage so that it does not give the stored force after a force application when the handle in their Basic position is traced back. The stored force is then released as soon as the lock is released, without the handle must be pressed.
Eine bevorzugte Weiterbildung der Erfindung besteht darin, dass die Sperre als elektromechanische Haltebremse ausgebildet ist, die bevorzugt nach dem Ruhestromprinzip arbeitet.A preferred embodiment of the invention is that the lock is designed as an electromechanical holding brake, which preferably operates on the quiescent current principle.
Wenn der Kraftspeicher mit einer vorgegebenen Vorlast beaufschlagt ist, so dass beim Niederdrücken der Handhabe ein elastischer Gegendruck vorhanden ist, wird ein Schutz der Vorrichtung gegen missbräuchliches Niederdrücken (Vandalismus) gewährleistet. Bevorzugt ist die Kennlinie des Kraftspeichers so ausgelegt ist, dass bei maximaler Betätigungskraft ein Anschlag erreicht wird. Die Kennlinie kann linear oder progressiv ausgelegt sein. Die Ansprechkraft der Sperre liegt zweckmäßigerweise unterhalb der maximalen Betätigungskraft.If the force accumulator is acted upon with a predetermined preload, so that when depressing the handle an elastic counter-pressure is present, a protection of the device against abusive depressions (vandalism) is ensured. Preferably, the characteristic of the force accumulator is designed so that at maximum actuation force a stop is reached. The characteristic curve can be linear or progressive. The response of the lock is suitably below the maximum operating force.
Es ist besonders vorteilhaft, dass der Kraftspeicher als Federspeicher ausgebildet ist. Als geeignet erweisen sich Zug- und Druckfedern, Schenkelfedern, Torsionsfedern und Spiralfedern.It is particularly advantageous that the energy accumulator is designed as a spring accumulator. Tensile and compression springs, torsion springs, torsion springs and coil springs prove to be suitable.
Es erweist sich als zweckmäßig, dass zwischen der Handhabe und dem Kraftspeicher ein erstes Getriebe angeordnet ist, über welches der Kraftspeicher beaufschlagt wird, und/oder dass zwischen dem Kraftspeicher und dem Dorn ein zweites Getriebe angeordnet ist, das vom Kraftspeicher beaufschlagt wird. Dabei ist es für das nachgeschaltete Schloss vorteilhaft, dass die Sperre mit dem zweiten Getriebe in Wirkverbindung steht, so dass der Dorn entlastet ist, solange die Sperre nicht gelöst ist.It proves to be expedient that between the handle and the energy storage, a first transmission is arranged, via which the force storage device is acted upon, and / or that between the energy storage and the mandrel, a second transmission is arranged, which is acted upon by the energy storage. It is advantageous for the downstream lock, that the lock is in operative connection with the second gear, so that the mandrel is relieved, as long as the lock is not released.
Für den Einsatz bei einem Fluchttürverschluss, der Panik- und Notausgangsanlagen einschließt, ist die Sperre als Ruhestrom-Sperre ausgebildet, wobei die Sperre vorzugsweise mit einem Nottaster oder mit einer Steuerzentrale in Wirkverbindung steht. Die Erfindung kann aber auch vorteilhafterweise bei Zugangskontrollanlagen eingesetzt werden. In diesem Fall ist die Sperre als Arbeitsstromsperre ausgebildet. Sie kann bei dieser Anwendung entweder mit einer Steuerzentrale oder mit einer Vorrichtung wirkverbunden sein, mit welcher eine Zugangsberechtigung eines Benutzers überprüft wird. Die Erfindung hat hierbei die Funktion eines Türöffners. Besonders vorteilhaft ist bei dieser Anwendung die Kombination mit einem gesteuerten elektromechanischen Schloss.For use in an escape door lock, which includes panic and emergency exit systems, the lock is designed as a quiescent current lock, wherein the lock is preferably in operative connection with an emergency button or with a control center. However, the invention can also be advantageously used in access control systems. In this case, the lock is designed as a work flow lock. In this application, it can be operatively connected either to a control center or to a device with which a user's access authorization is checked. The invention here has the function of a door opener. Particularly advantageous in this application is the combination with a controlled electromechanical lock.
Es ist besonders vorteilhaft, dass die Handhabe als Druckstange oder Griffstange ausgebildet ist. Druckstangen und Griffstangen werden bei Fluchttürverschlüssen eingesetzt. Druckstangen sind dabei in Fluchtrichtung linear verschiebbar in einem Gestell oder einer Montageeinheit geführt. Griffstangen werden zwischen zwei Schwenkarmen oder drehbaren Halterungen gelagert und in Fluchtrichtung oder in einem nach unten gerichteten Bogen bewegt.It is particularly advantageous that the handle is designed as a push rod or handle bar. Push rods and handle bars are used for escape door closures. Push rods are guided linearly displaceable in the direction of escape in a frame or a mounting unit. Handlebars are stored between two pivoting arms or rotatable brackets and moved in the direction of escape or in a downward bow.
Nach einer vorteilhaften Weiterbildung ist die Handhabe am Dorn angebracht und der Dorn ist zweigeteilt in einen schlossseitigen Dornabschnitt und einen handhabeseitigen Dornabschnitt, und zwischen den beiden Dornabschnitten ist der Kraftspeicher angeordnet. Bevorzugt ist dabei eine geteilte Drückernuss zur Aufnahme des schlossseitigen und des handhabeseitigen Dornabschnitts vorhanden.According to an advantageous embodiment, the handle is attached to the mandrel and the mandrel is divided into two parts in a lock-side mandrel portion and a handle-side mandrel portion, and between the two mandrel portions of the energy storage is arranged. In this case, a split pusher nut for receiving the lock-side and handle-side mandrel section is preferably present.
Die Erfindung kann dadurch vorteilhafterweise als eine einbruchsichere elektromechanisch gesteuerte Schlossvorrichtung ausgebildet werden, dass an dem schlossseitigen Dornabschnitt eine weitere Handhabe angeordnet ist, dass auch der schlossseitige Dornabschnitt zweigeteilt und mit einer dazwischen liegenden elektrisch steuerbaren Kupplung versehen ist, und dass die Kupplung bevorzugt mittels Arbeitsstrom betätigbar ist.The invention can be advantageously designed as an intrusion-proof electromechanically controlled lock device, that on the lock-side mandrel portion another handle is arranged, that the lock-side mandrel portion is divided into two and provided with an interposed electrically controllable coupling, and that the clutch preferably actuated by working current is.
Herkömmliche Schlösser können vorteilhafterweise mit einem Dorn nachgerüstet werden, der in zwei Dornabschnitte geteilt ist und bei welchem zwischen beiden Dornabschnitten die Kraftspeicher angeordnet ist.Conventional locks can advantageously be retrofitted with a mandrel, which is divided into two mandrel sections and in which between the two mandrel sections the energy storage is arranged.
Ferner können herkömmliche Schlösser dadurch nachgerüstet werden, dass im Schlossbeschlag eine geteilte Drückernuss und ein Federspeicher angeordnet sind, der mit einem Teil der Drückernuss in der Weise wirkverbunden ist, dass mit einer Drehbewegung des Drückerteils der Federspeicher gespannt wird, und der mit dem anderen Teil der Drückernuss in der Weise wirkverbunden ist, dass er vom Federspeicher beaufschlagt wird, wenn die Sperre gelöst ist.Furthermore, conventional locks can be retrofitted that in the lock fitting a split follower and a spring accumulator are arranged, which is operatively connected to a part of the follower in such a way that is stretched with a rotational movement of the pusher of the spring accumulator, and with the other part of the Follower is operatively connected in such a way that it is acted upon by the spring accumulator when the lock is released.
Ein Schlossbeschlag kann bevorzugt dadurch weitergebildet werden, dass ein Teil der Drückernuss mit einem treibenden Getriebe zum Beaufschlagen des Kraftspeichers in Verbindung steht, und dass der andere Teil mit einem vom Kraftspeicher abgehenden Getriebe verbunden ist, wobei bevorzugt auch die Sperre im Schlossbeschlag angeordnet ist.A lock fitting can preferably be further developed in that a part of the follower is in communication with a driving gear for acting on the force accumulator, and that the other part is connected to an outgoing from the power storage gear, wherein preferably also the lock is arranged in the lock fitting.

Grundsätzlich kann das Schloss 9 als herkömmliches Fluchtürschloss ausgebildet sein, das man von außen nur mit einem Schlüssel öffnen kann. Da die Entriegelungsvorrichtung 7 bzw. 7' dem Schloss 9 innenseitig vorgeschaltet ist, wobei der Kraftfluss von der innenseitigen Handhabe 12 auf das Schloss 9 elektrisch gesteuert ist, kann das Schloss 9 auch als ein an sich bekanntes Sicherheitsschloss mit einer geteilten Drückernuss und einer mit Arbeitsstrom gesteuerten Kupplung ausgebildet sein, welches einen Zugang von außen ermöglicht. Die Tür kann daher auch - wie beispielhaft dargestellt - mit einer Mehrpunktverriegelung versehen sein, die darin besteht, dass das Schloss 9 über zwei Gestänge 8 mit zwei Schließkästen 4 verbunden ist, die jeweils einen weiteren Schließriegel 6' aufweisen. Anstelle eines Schließriegels oder mehrerer Schließriegel können auch Fallen vorhanden sein.Basically, the
Neben dem Türblatt 10 sind wandseitig ein Nottaster 14 und ein Schlüsselschalter 15 zum autorisierten Scharfschalten der Türschlossvorrichtung 11 angeordnet. In einer Grundstellung, in welcher die Tür verschlossen ist, ist die Türschlossvorrichtung 11 elektromechanisch gesperrt, so dass ein Niederdrücken der Handhabe 12 nicht zur Freigebe der Türschlossvorrichtung 11 führt und die Tür nicht geöffnet werden kann. Nur wenn der Nottaster 14 gedrückt wurde oder der Schlüsselschalter 15 von einem autorisierten Bediener betätigt wurde, wird die Sperre gelöst und das Schloss 9 und die Tür sind zum Öffnen freigegeben.In addition to the
Die Darstellungen gemäß
Ein als Vierkant ausgebildeter zweigeteilter Dorn 17 ist aus dem Schlosskasten 16 herausgeführt. Die Handhabe ist an dem aus der Zeichenebene herausragenden freien Ende des Dorns 17 angebracht, aber in
Die beiden Dornabschnitte 17a, 17b sind an ihren zugewandten Enden in einer zweigeteilten weiteren Drückernuss 18 gelagert, wobei der schlossseitige Dornabschnitt 17b in einer schlossseitigen Nuss 18a und der handhabeseitige Dornabschnitt 17a in einer handhabeseitigen Nuss 18a zu liegen kommt. Die schlossseitige und die handhabeseitige Nuss 18a, 18b sind zur besseren Unterscheidung wieder unterschiedlich groß dargestellt. Durch die Teilung des Dorns 17 und der Drückernuss 18 ist der unmittelbare Kraftfluss von der Handhabe 12 (
Wie nachfolgend im Einzelnen erläutert wird, ist der Handhabe 12 ein mechanischer Kraftspeicher 21 nachgeschaltet, welcher eine auf die Handhabe 12 aufgebrachte Kraft speichert. Ausgangsseitig steht der Kraftspeicher 21 mit dem schlossseitigen Dornabschnitt 17b in der Weise in Wirkverbindung, dass die gespeicherte Kraft in ein Drehmoment gewandelt werden kann, das auf den schlossseitigen Dornabschnitt 17b wirkt. Das Drehmoment erzeugt eine Drehung des schlossseitigen Dornabschnitts 17b und damit ein Rückschließen der Schließriegel 6, 6' (
An den beiden Dornabschnitten 17a, 17b ist jeweils ein handhabeseitiges und ein schlossseitiges Getriebe 20a, 20b angeordnet, die im vorliegenden Beispiel als ein handhabeseitiger Stellhebel 19a bzw. als ein schlossseitiger Stellhebel 19b ausgebildet und drehfest mit den jeweiligen Dornabschnitten 17a, 17b verbunden sind. Die beiden Stellhebel 19a, 19b sind über den Kraftspeicher 21 verbunden. Der Kraftspeicher 21 ist als Federspeicher, hier als Zugfeder 21a, ausgebildet. Am schlossseitigen Stellhebel 19b ist ein Abstandshalter 38 zum handhabeseitigen Stellhebel 19a ausgebildet, dessen Funktion in der Beschreibung von
Ferner ist eine elektromagnetische Sperre 22 mit einem Elektromagnet 23 und einem Anker 24 vorhanden, der zusammen mit einem Sperrhebel 25 eine zweiarmige Sperrklinke bildet. Die Sperre 22 wirkt als Haltebremse für den schlossseitigen Stellhebel 19b. Sie steuert den schlossseitigen Stellhebel 19b als Drehsperre. Sie hindert ihn in einer Grundstellung, die in
In der Grundstellung der Türschlossvorrichtung gemäß
Wird die Handhabe 12 im Uhrzeigersinn niedergedrückt, nimmt sie den zugehörigen handhabeseitigen Stellhebel 19a mit. Da der schlossseitige Stellhebel 19b vom Sperrhebel 25 in seiner Position gehalten wird, wird die Zugfeder 21a gedehnt und die Bewegung erfolgt gegen die Kraft der Zugfeder 21a. Wie
Wird dagegen nach dem maximalen Niederdrücken der Handhabe 12 und dem Speichern der aufgebrachten Kraft in der Zugfeder 21a die Sperre 22 gelöst, indem der Strom durch Niederdrücken des Nottasters 14 (
Es ist somit ersichtlich, dass die von der Handhabe 12 ausgeübte Kraft nicht unmittelbar auf den schlossseitigen Dornabschnitt 17b geführt wird, sondern nur mittelbar über die Zugfeder 21a mit einer vorgegebenen Federspannung.It can thus be seen that the force exerted by the
Wenn nun die Handhabe 12 losgelassen wird, wird der handhabeseitige Stellhebel 19a durch eine Rückstellfeder 27 gegen den Uhrzeigersinn in die Grundstellung gezogen. Über den Abstandshalter 38 nimmt er den schlossseitigen Stellhebel 19b in seine Ausgangsposition mit. Um die Türschlossvorrichtung wieder in die Grundstellung zu bringen, wird die Sperre 22 scharf geschaltet, und die Schließriegel 6, 6' (
Bei dem zweiten Ausführungsbeispiel einer Entriegelungsvorrichtung 7' gemäß
Das schlossseitige Getriebe 20b' besteht aus einer linear bewegbaren schlossseitigen Druckstange 34b, die mit einer schlossseitigen Nut 30b versehen ist, einer schlossseitigen Nuss 18b', die einen schlossseitigen Nocken 28b aufweist, der mit der schlossseitigen Nut 30b in der schlossseitigen Druckstange 34b in Eingriff steht, und einer Wippe 35 zwischen der schlossseitigen Druckstange 34b und dem Kraftspeicher 21'. Der ausgangsseitige Block 36 ist gegen einen ersten Arm 35b der Wippe 35 abgestützt. Der zweite Arm 35c ist über einen Stift 35d mit einem Langloch 29 der schlossseitigen Druckstange 34b in Eingriff. Die Wippe 35, die eine ortsfeste Schwenkachse 35a aufweist, ist mit dem Ausgang des Kraftspeichers 21', d.h. mit dem ausgangsseitigen Block 36 verbunden. Die schlossseitige Druckstange 34b ist mit einem Zapfen 38 versehen, der mit einer elektromechanischen Sperre 22' in der Weise zusammen wirkt, dass die schlossseitige Druckstange 34b in einer Grundposition blockiert ist. Um die Figur übersichtlich zu halten, ist lediglich der Sperrhebel 25' der Sperre 22' dargestellt. Die Sperre 22' wirkt als Haltebremse, wobei der Sperrhebel 25' die schlossseitige Druckstange 34b bei Ruhestrom in der Grundposition hält. In der Grundposition ist der schlossseitige Teil der Vorrichtung somit nicht mit einer Vorspannung belastet. Bei gelöstem Sperrhebel 25' kann sich die Druckstange abhängig von der im Kraftspeicher 21 gespeicherten Kraft nach oben bewegen.The lock-
Solange die schlossseitige Druckstange 34b vom Sperrhebel 25 in der Grundposition gehalten ist, ist auch die Wippe 35 blockiert und hält den ausgangsseitigen Block 36 ebenfalls in der Grundstellung gegen eine Federspannung, die über den eingangsseitigen Block 31 auf die Druckfedern 21b aufgebracht wird. Auch bei einer derartigen Vorlast auf die Handhabe 12 wird die Vorlast nicht auf den schlossseitigen Teil der Vorrichtung übertragen.As long as the lock-
Wird die Handhabe 12 im Uhrzeigersinn gedrückt, verursacht der handhabeseitige Dornabschnitt 17a eine entsprechende Drehung der handhabeseitigen Nuss 18a, wobei der handhabeseitige Nocken 28a die handhabeseitige Druckstange 34a nach unten auslenkt. Dadurch wird der Verbindungssteg 33 zusammen mit den Spannstangen 32 und dem eingangsseitigen Block 31 nach unten gezogen, wobei die Druckfedern 21b gegen den ausgangsseitigen Block 36 gespannt werden. Ein über die Handhabe 12 auf den handhabeseitigen Dornabschnitt 17b aufgebrachtes Drehmoment bewirkt also eine Beaufschlagung des Federspeichers 21' und eine Speicherung der aufgebrachten Kraft bzw. des aufgebrachten Drehmoments. Die Kraft wird gespeichert, bis die Sperre 22' gelöst wird. Solange die Sperre 22' nicht gelöst ist, dient der beim Niederdrücken der Handhabe 12 zu überwindende Widerstand dazu, die Vorrichtung gegen mutwillige Beschädigungen zu schützen. Es ist also kein zusätzlicher Vandalismusschutz an der Handhabe 12 erforderlich.When the
Wird die Sperre 22' bei niedergedrückter Handhabe 12 gelöst, indem entweder ein Nottaster (siehe
Wird die Handhabe 12 anschließend losgelassen, wird die handhabeseitige Druckstange 34a durch den handhabeseitigen Nocken 30a nach oben geschoben, bewegt sich der eingangsseitige Block 31 zusammen mit dem Verbindungssteg 33 nach oben, die Druckfedern 21b werden entlastet, sie entspannen sich, und der ausgangsseitige Block 36 sowie der eingangsseitige Block 31 nehmen die Grundstellung ein, wobei auch die Handhabe 12 entgegen dem Uhrzeigersinn in ihre Grundstellung zurückgeführt wird. Der Kraftspeicher 21' wirkt somit als Rückstelleinrichtung für die Handhabe 12. Die schlossseitige Druckstange 34b wird über eine Drehung des schlossseitigen Dorns 17b entgegen dem Uhrzeigersinn über die schlossseitige Nuss 18b nach unten in die Grundstellung bewegt. Die Drehung des schlossseitigen Dorns 17b entgegen dem Uhrzeigersinn erfolgt durch eine schlossseitige Feder (nicht dargestellt), wie sie herkömmlicherweise in einem Schloss zur Rückstellung der Handhabe 12 vorhanden ist.When the

Bei der dritten Ausführungsform gemäß
Unterhalb der Entriegelungsvorrichtung 43 in das Türblatt 41 eingelassen befindet sich ein Schlosskasten 50 mit einem üblichen Türschloss, dessen Türschloss-Drückernuss 52 mit der Entriegelungsvorrichtung 43 in Eingriff steht. Das Türschloss ist im Unterschied zu den Ausführungen gemäß
Der Dorn 42 der Entriegelungsvorrichtung 43 ist zweigeteilt in einen handhabeseitigen Dornabschnitt 42a und einen schlossseitigen Dornabschnitt 42b. Der Eingriff der Entriegelungsvorrichtung 43 mit der Türschloss-Drückernuss 52 erfolgt über den schlossseitigen Dornabschnitt 42b. Der handhabeseitige Dornabschnitt 42a ist in Eingriff mit der Drückernuss 49 an der Montageplatte 44. Im Übrigen entspricht die Mechanik der Entriegelungsvorrichtung 43 derjenigen Mechanik, die anhand der Ausführungen gemäß
Demnach weist sie einen Kraftspeicher, eine zweigeteilte Drückernuss, welche die beiden Dornabschnitte 42a, 42b in einer schlossseitigen bzw. handhabeseitigen Drückernuss aufnimmt, ein handhabeseitiges und ein schlossseitiges Getriebe sowie eine elektromagnetische Sperre auf.Accordingly, it has a force accumulator, a two-part pusher which accommodates the two
Die Druckstange 40 ist zur Durchführung einer Drückerbewegung an einer türblattseitigen Montageplatte 44 verschiebbar gelagert, die parallel zum Türblatt 41 verläuft. Über ein Umlenkgetriebe wird die lineare Bewegung der Druckstange 40 in eine Schwenkbewegung einer Drückernuss 49 umgesetzt, die in der Montageplatte 44 angeordnet ist, und welches folgendermaßen wirkt. Über einen zweiarmigen Umlenkhebel 45 an der Montageplatte 44, dessen Schwenkachse parallel zur Montageplatte 44 und quer zur Längsrichtung der Druckstange 40 ausgerichtet ist, wird eine Bewegung der Druckstange 40 umgelenkt und auf einen Schieber 46 übertragen, der parallel zur Montageplatte 44 und an der Montageplatte 44 geführt ist, und dadurch in eine Bewegung in Längsrichtung der Druckstange 40 umgesetzt. Der Schieber 46 ist über einen angelenkten Hebel 47 mit einem Schwenkarm 48 einer Drückernuss 49 verbunden. Diese Drückernuss 49 nimmt den handhabeseitigen Dornabschnitt 42a der Entriegelungsvorrichtung 43 auf. Die Druckstange 40, die Montageplatte 44, der Umlenkhebel 45, der Schieber 46, der Hebel 47 und die Drückernuss 49 sind als eine eigenständige Montageeinheit 54 ausgebildet, die auf die Entriegelungsvorrichtung 43 bzw. deren Gehäuse 53 montiert wird.The
Wird die Druckstange 40 gedrückt, wird der mit der Druckstange 40 in Verbindung stehende Arm 45a des Umlenkhebels 45 nach unten bewegt und der mit dem Schieber 46 in Verbindung stehende Arm 45b bewegt den Schieber 46 entlang der Montageplatte 44. Diese translatorische Bewegung führt über den Hebel 47 und den Schwenkarm 48 zu einer Verdrehung des handhabeseitigen Dornabschnitts 42a. Die Wirkung ist die gleiche, wie sie oben im Zusammenhang mit der Betätigung der Handhabe bei den Beispielen gemäß
Der Schlosskasten 50, das Gehäuse 53, die Entriegelungsvorrichtung 43 und die Montageeinheit 55 sind relativ zueinander so angeordnet, dass der Zugang zum Schließzylinder 51 vom Gehäuse 53 und der Montageeinheit 55 nicht abgedeckt ist. Das Schloss im Schlosskasten 50 kann daher unbehindert mit einem Schlüssel betätigt werden.The

Der Dorn 42 verbindet die Drückernuss 49 auf der Montageplatte 44 mit der Türschloss-Drückernuss 52.The
Anders als bei der Ausführung gemäß
Die Sperre 22 weist einen Sperrhebel 25 auf, der elektromagnetisch blockiert oder freigegeben wird, und welcher mit einem Zapfen 38 auf dem Schieber 46' zusammenwirkt.The
Wird die Druckstange 40 niedergedrückt, wird der Hebel 45 ausgelenkt, und die Zugfeder wird gespannt, wenn die Sperre 22 den Schieber 46' blockiert. Die aufgebrachte Kraft wird in der Zugfeder gespeichert, solange die Druckstange 40 gedrückt ist.
