Description

The invention relates to a door lock device for a door with at least one door leaf. The door can be a single-leaf door or a multi-leaf door, preferably a double-leaf door. There are in particular doors with rotary wing in question, preferably with stop wing. Versions with swing door wings are also possible. Preferred applications are doors in escape and rescue routes, so-called panic doors.

The door lock device comprises a door lock which can be mounted in or on the door leaf and has a lock latch and / or a bolt. Furthermore, the door lock device comprises an actuating handle which can be mounted on the door leaf and has an actuating element and a transmission device, by way of which the actuating element can be connected to the door lock in order to actuate the door lock.

Such door lock devices are known in practice, for example on doors for escape and rescue routes. In this area, the actuating handle is often designed as an actuating linkage, which is mounted horizontally on the door leaf. There are known actuating linkage, which have as an actuating handle a pivotable about a horizontal axis handlebar. But there are also known actuating linkage, which have a push rod as an actuating element, which are linearly movable perpendicular to the door leaf level.
In the DE 10 2010 028 647 a door lock device is described in which the lock nut of the door lock cooperates with an unlocking spring which is chargeable upon actuation of the actuating handle, on the one hand to obtain vandalism protection via the damping of the spring and on the other hand to support the unlocking of the door lock on the charged spring , From the US 5 011 199 a panic lock according to the preamble of claim 1 is known, wherein between the actuating handle and the lock, a clutch spring is arranged. The present invention has for its object to provide a door lock device, which provides high security and at the same time convenient handling when used in doors in escape and rescue routes.

It is essential in the inventive solution according to claim 1 that the transmission device of the actuating handle has a first transmission element which is coupled to the actuating handle and / or can be coupled and has a second transmission element with the door lock is coupled and / or coupled. Between the first Transmission element and the second transmission element is a clutch spring switchable and / or connected. The clutch spring is configured and connected such that in a first position it couples the first transmission element to the second transmission element and in a second switching position does not couple the two transmission elements, so that upon actuation of the actuating handle the first transmission element is actuated exclusively or primarily the second transmission element is not taken or at least not taken away so that in this case the unlocking of the door lock takes place. In this solution according to the invention is further essential that the transmission device has an electric motor and a blocking device which can be switched on and off. The electric motor and the blocking device cooperate with the clutch spring in such a way that the clutch spring is charged by the electric motor and the supercharged clutch spring is blocked when the blocking device is switched on, so that when the supercharged clutch spring is blocked, the first transmission element and the second transmission element are decoupled. This means that in this position by actuation of the actuating handle no actuation of the door lock, that is, in particular no unlocking of the door lock takes place. Only when the blocking device is switched off, the clutch spring in its unlocked position couples the first transmission element with the second transmission element. In this position, an actuation of the door lock, preferably an unlocking is possible by an actuation of the actuating handle.

The transmission elements of the actuating device may be one-part components or else components composed of multiple parts. The components may be formed as any gear parts.

It is essential that between these so-called transmission elements, the clutch spring is connected directly or indirectly and cooperates with the blocking device and the electric motor in the manner described. In preferred embodiments, the first transmission element and the second transmission element are designed as push rods, which are guided linearly displaceable in the door leaf fixed bearing frame of the actuating handle. The actuating handle is formed in preferred embodiments as a push rod, which is preferably connected via a transmission with the first transmission element. The second transmission element is preferably coupled with a lock nut of the door lock. The lock can be designed as a mortise lock. Instead of a mortise lock but also an overlying lock can be provided. Embodiments are possible in which the door lock device is designed as a resting so-called RIM embodiment, in which the latch actuated by the actuating handle interacts with a catch plate resting on the stationary door frame.

As regards the arrangement of the other components, embodiments are possible in which the blocking device and / or the clutch spring and / or the electric motor is supported on the first transmission element or on the second transmission element. Particularly preferred embodiments are that provide that the electric motor and the clutch spring are supported on different transmission elements, as provided for in claim 3. There are also embodiments advantageous in which the electric motor and the blocking device are supported on different transmission elements, as provided by the patent claim 4.

In preferred embodiments, it can be provided that a connecting device is provided between the first transmission element and the second transmission element, which prevents compression of the spring by the first transmission element when the blocking device is disengaged. The connecting device may be formed as a length-adjustable blocking rod, for example telescopic rod, which blocks in the compression direction of the spring in the longitudinal direction and not blocked in the direction of expansion of the spring in the longitudinal direction.
Preferably, the connecting device is designed in particular switchable, and is forcibly effective in a release of the clutch spring. In order to continue to ensure actuation of the door lock and also to allow tolerance compensation is provided that the connecting device locks only in the direction of compression of the clutch spring and allows spring movements to relax the spring. During the charging of the clutch spring by the electric motor of this switches the connection device ineffective. The connecting device may be formed, for example, as a wedge or ball clamping device, which is formed telescopically on or extendable. Another solution, which is not part of the invention, provides that the door lock device is constructed as follows. It has a door lock which can be mounted in or on the at least one door leaf with a latch and / or a bolt, an actuating handle which can be mounted on the at least one door with an actuating element, a clutch spring and a transmission device, around the door lock either via the actuating element or the clutch spring to press.

It is provided that the transmission device has a first transmission element which is coupled to the actuating handle and / or can be coupled and has a second transmission element which can be coupled to the door lock and / or coupled, wherein the transmission device has a clutch spring which is fixed to the housing supported bearing and the second transmission element is switchable and / or connected and can be charged via an electric motor of the transmission device, wherein the transmission device has a switchable coupling element to couple the first transmission element and the second transmission element.

1. a) dass das zweite Übertragungselement mit der vom E-Motor aufgeladenen Kupplungsfeder kuppelbar ist, um das Türschloss zu entriegeln, während das zweite Übertragungselement vom ersten Übertragungselement entkuppelt ist; oder
2. b) dass das zweite Übertragungselement mit dem ersten Übertragungselement kuppelbar ist, um das Türschloss zu entriegeln, während die Kupplungsfeder von dem gehäusefest abgestützten Lager entkuppelt ist.

Hereby is provided:

1. a) that the second transmission element with the charged by the electric motor clutch spring is coupled to unlock the door lock, while the second transmission element is decoupled from the first transmission element; or
2. b) that the second transmission element with the first transmission element is coupled to unlock the door lock, while the clutch spring is decoupled from the housing fixedly supported bearing.

It is essential in this solution that the clutch spring is not coupled to the handle, but is connected on the one hand to the second transmission element and on the other hand with the bearing fixed to the housing. The unlocking of the door lock can be done independently of each other by the charged by the electric motor clutch spring or by the handle.

In preferred embodiments, it is provided that the bearing supported on the housing is designed as a movable bearing, preferably as a pivot bearing or sliding bearing and is connected to an actuator which moves out of the range of movement of the clutch spring supported the housing fixedly supported out of the range of movement of the clutch spring, when not disengaged blocking device, the first transmission element is pressed. The movable bearing can be designed as a switchable bearing, which can be brought into different positions.

It can be provided that the transmission device has a blocking device which cooperates with the clutch spring in such a way that the clutch spring can be charged by the electric motor and the charged clutch spring can be blocked when the blocking device is switched on, so that when the charged clutch spring is blocked, the first transmission element and the second transmission element are decoupled.

In all embodiments with blocking device can be provided that the blocking device is designed as electrically or manually switchable blocking device. Embodiments are also possible in which the blocking device is forcibly switched by the actuation of the handle.

In order to avoid accidental unlocking of the door lock with a non-actuated first actuator, it can be provided that the housing fixed bearing is designed as a pivot bearing or sliding bearing and has an actuator or is connected to an actuator, the motor or a motor-side bearing of the clutch spring swings out or pushes out of the range of movement of the spring when disengaged Blocking the first actuator is not actuated. When disengaged blocking and folded out of the range of movement of the clutch spring bearing, the clutch spring can then relax without exerting a force on the second actuator and unlock the lock. In order nevertheless to ensure actuation of the door lock, the first can be connected to the second actuating element via an additional, in particular switchable coupling element. After the door lock has been actuated, the engine or the engine-side bearing can be swung back again and the clutch spring recharged via the engine. However, the unloading of the clutch spring can also be prevented, for example, via a corresponding structural design, for example a switchable blocking device on the clutch spring.

Embodiments are particularly preferred which have a coupling element which can be switched on and off, via which the first transmission element and the second transmission element can be coupled, for example, to obtain a temporary coupling of the two transmission elements for actuation of the door lock by an authorized person or else to actuation of the door lock while the clutch spring is being charged via the electric motor. The coupling element can be switched off in normal operation, that is to be connected so that no coupling of the two transmission elements takes place in normal operation via the coupling element. In order to obtain a coupling for a door lock operation by an authorized person, an electrical access control device can be connected to the coupling element in order to switch on the coupling by the authorized person. Even in an emergency can via an emergency switch, a coupling of the Transmission elements via the on and off switchable coupling element.

In preferred embodiments, it may be provided that the coupling element is switchable via an electrical access control device or a mechanical and / or electrical key and / or an emergency switch to turn on the coupling element for coupling the first transmission element and the second transmission element.

The control of the pawl and thus the coupling or releasing can take place in a quiescent current mode or also in a working current mode.

In the working current mode, it is provided that a coupling of the first transmission element to the second transmission element takes place, in that a solenoid is energized and acts on the pawl in the direction of the toothing. If the solenoid is de-energized, the pawl is acted upon by a spring disengaged, z. B. pulled out via a tension spring from the teeth to dissolve the coupling.

In the quiescent current mode it is provided that a coupling of the first transmission element with the second transmission element takes place by the solenoid being de-energized and a spring, preferably a compression spring acts on the pawl in the direction of the toothing. Will the Energized solenoid, it pulls the pawl out of the toothing against the force of the compression spring out to release the coupling.

It is advantageous in this embodiment also that a coupling between the first transmission element and the second transmission element regardless of the position of the transmission elements to each other or an actuation of the first transmission element can be effected via a manual actuation handle. With correspondingly fine toothing, the coupling of the two transmission elements can take place virtually continuously with one another.

In a blocked door lock naturally occur very high actuation forces. It is therefore advantageous in this embodiment that a possible charging of the clutch spring is effectively prevented by a manual actuation of the actuating handle by the direct coupling of the transmission elements. This prevents that in addition to the high operating forces of the lock in the event of jamming also force must be expended to charge the clutch spring. If a jammed lock is then released by means of the direct manual action via the actuating element, it is possible for the clutch spring to be able to open the door lock or at least the opening due to the energy stored in the spring after the jammed door lock has been pressed over to support the door lock.

There are advantageous embodiments are possible in which the electric motor is designed so that its output is selectively driven in a first direction and in a second direction, wherein the output is formed in the first direction for acting on the clutch spring and the output in the second direction for acting on a third transmission element is designed for the motor unlocking the door lock. This means that in these versions in addition a motor unlocking the door lock is possible.

In preferred embodiments, it may be provided that the coupling spring cooperates with the first transmission element and the second transmission element or with the second transmission element and the bearing fixed to the housing such that the spring force of the clutch spring is formed on the door lock so acting that the unlocking of the door lock alone done by the spring force of the clutch spring.

In embodiments in which the clutch spring is switchable between the first and the second transmission element is provided that the coupling spring cooperates with the first transmission element and the second transmission element such that the spring force of the clutch spring is formed on the door lock acting so that the unlocking of the door lock takes place solely by the spring force of the clutch spring or that the spring force of the clutch spring at least contributes to the unlocking of the door lock.

So there are also possible embodiments in which the clutch spring not only has a coupling function for the two transmission elements, but also serves as a spring for unlocking the door lock, that is, in these embodiments, the unlocking of the door lock is done solely by the spring force of the clutch spring or that the spring force of the clutch spring contributes at least in part to the unlocking of the door lock.

In preferred embodiments, it is provided that the actuating handle is designed as a rod handle, wherein the actuating element is designed as a vertically movable to the door leaf level push rod or as a pivotable about a horizontal axis handlebar. It may be provided here with particular advantages that the first transmission element is designed as a linearly displaceable push rod and / or that the second transmission element is designed as a linearly displaceable push rod. These push rods may preferably be guided linearly and parallel to the door leaf level in a parallel to the door leaf level base plate. Designs with differently mounted actuating handles are also possible, e.g. Versions with handle handle.

Fig. 1 schematically shows a door with a in a door frame TR by means of two hinges TB rotatably mounted door leaves TF. The door may be an escape and escape door, also known as a panic door. The door hinges TB are spaced apart along a vertical axis of rotation of the door. The door hinges TB are at an in Fig. 1 Left shown vertical side of the door provided. The door leaf TF is preferably a stop pivot wing. Designs of the door with a pendulum wing are possible with appropriate design of the door hinges.

On the door leaf TF designed as a push rod device actuating handle 10 is mounted. This actuating handle 10 cooperates with a door lock 20, which is mounted in the illustrated case in the door leaf TF designed as a mortise lock.

In the Fig. 2 to 5 is the in Fig. 1 Door leaf mounted door lock device shown schematically in a concrete embodiment. The actuating handle 10 is formed in the illustrated case as a push rod device. This push rod device has an actuating element 1 as a perpendicular to the door leaf level movable push rod. With the operation of this push rod 1, a pivotable in the door leaf bearing 1l 1h lever is actuated, which engages with its one end to the inside of the push rod 1 and with its other end in a first push rod 1a, in the door leaf fixed bearing 1l of the push rod device linearly displaceable is arranged. Parallel to this first push rod 1a, a second push rod 1b is also mounted linearly displaceable in the door leaf bearing. This second push rod 1b is connected to the lock nut 20n of the door lock 20 mounted in the door leaf via a crank rocker or the like. Between the first push rod 1a and the second push rod 1b, a clutch spring 1f is arranged. This clutch spring 1f is formed in the illustrated case as a helical compression spring. It is supported with its one end on the second push rod 1b and points to her the other end to a spring plate 1ft, which can be acted upon by the output 1ma of a supported on the first push rod 1a electric motor 1m to charge the clutch spring 1f, that is to compress in the illustrated case. This position is in Fig. 3 shown. On the first push rod 1a a driver stop 1aa is arranged, which is in abutment with the push rod 1b. On the second push rod, a driver stop 1bb is arranged, which is in abutment with the push rod 1a. On the second push rod 1b, an electric locking device 1e is arranged, on which the spring 1f in the charged, ie in the illustrated case compressed state, is supported with its spring plate. This position shows Fig. 5 , In this position, the second push rod 1b is decoupled from the first push rod 1a, ie upon actuation of the first push rod 1a by the push rod formed as the actuating element 1, the first push rod 1a in Fig. 5 shifted to the right without the second push rod 1b, which is connected to the lock nut 20n, taken along. The supported on the first push rod 1a motor 1m is arranged here with retracted output, so that in Fig. 5 in the initial position existing distance a between the motor output 1ma and the detected on the blocking device 1e spring plate 1ft is present and thus the first push rod 1a in this movement path is freely movable without abutment against the spring plate 1ft, the supported on the second push rod 1b clutch spring 1f reach.

When the blocking device 1e is turned off, the blocking of the clutch spring 1f is released, with the result that the clutch spring 1f relaxes and in the illustrated case in FIG Fig. 5 the spring plate is moved to the left and comes into abutment with the output 1ma of the electric motor 1m supported on the first push rod 1a. This position is in Fig. 3 shown. In this position, not shown, the first push rod 1a is coupled to the second push rod 1b. This means that upon actuation of the first push rod 1a via the push rod 1, wherein the push rod 1 in Fig. 3 is moved to the right, the second push rod 1b is taken, ie also moved to the right. The second push rod 1b coupled to the lock nut 20n thus unlocks the lock 20.

The actuator 10 has, as can be seen in the figures, nor a coupling element 1k, which is decoupled in normal operation of the device and is only coupled when a legitimate the lock 20 should operate. For this purpose, the coupling element 1k is connected via an access control device, not shown in the figures, which is switchable via an authorized person such that the coupling element 1k couples the first push rod 1a to the second push rod 1b. In the coupled state, the first push member 1a is displaced to the right in the illustration in the figures during the actuation of the actuating handle 10 by means of the push rod 1, thereby taking the second push rod 1b in the same direction, whereby the lock 20 via the push rod 1b is actuated.

The unlocking of the door lock 20 takes place in this embodiment according to the FIGS. 3 to 5 about three alternative ways.
In path 1, the second push rod 1b is coupled via the clutch spring 1f with the first push rod 1a. The unlocking is done by the operation of the handle 1. The push rod 1a is in the unlocking in the FIG. 3 moved to the right. In this case, the second push rod 1b connected to the lock nut 20n becomes unlocked in the right direction moved. The intermediate clutch spring 1f constitutes a transmission means between the two push rods. In preferred embodiments, the bias of the clutch spring 1f is greater than the maximum unlocking force.
In way 2, the second push rod 1 b is mechanically coupled via the coupling device 1 k with the first push rod 1 a, for example, by pressing an emergency button. The unlocking is done by the operation of the handle 1 due to the direct mechanical coupling between the first push rod 1a and the second push rod 1b.
In way 3, the unlocking takes place by the discharge of the charged over the electric motor clutch spring 1 f from the position in FIG. 5 , This occurs when the activation of the blocking device 1e takes place when the handle is already actuated and the coupling device 1k in FIG. 5 no longer couples.

This in Fig. 6 shown modified embodiment differs from the embodiment of FIGS. 2 to 5 only in that the electric motor 1m, which is supported on the first push rod 1a, with its output with a transmission element 1ü cooperates when the engine pulls its output, that runs in the opposite direction to the first direction in which the output of the Clutch spring 1f has charged. The transmission element 1 u, with which the output of the motor cooperates in movements of this opposite direction, is coupled to the lock nut 20 n, so that the lock is unlocked when the transmission member is acted upon by the output 1 ma of the counter-rotating electric motor 1 m. The motor 1m, which primarily serves to charge the clutch spring 1f, thus additionally acts as an unlocking motor for the lock in this function.

In the illustrated embodiments of the FIGS. 2 to 6 Thus, the actuating handle 10 designed as a push rod device comprises a transmission device connected between the push rod 1 and the lock 20, comprising the first push rod 1a, which is coupled to the push rod 1, and the second push rod 1b, which is coupled to the lock. The push rod 1b actuates the lock 20 during its movement. The push rod 1a is moved when the push rod 1 is pressed. Both rods 1a, 1b can be coupled by the coupling spring 1f. The clutch spring 1k is greater than the maximum necessary actuation force in its coupling position, as shown in FIG Fig. 5 is shown biased. This ensures that an actuation of the push rod 1 even under preload leads to unlocking the lock 20. So that the clutch spring 1f does not press the push rods 1a, 1b apart indefinitely, stops 1bb and 1aa are provided on which the push rods 1a, 1b are supported on one another.

The electric motor 1m arranged in series with the clutch spring 1f is capable of the clutch spring 1f via its bias, which in the initial position, which in Fig. 3 is shown to compress further. During this process starting from the position in Fig. 3 remains a coupling of the push rods 1a, 1b on the coupling element 1k obtained, so that the panic function, ie the possibility of unlocking the lock on the push rod device is also given during the charging process. The clutch spring 1f is locked in its end position of the charge via a preferably electromechanical locking by the blocking device 1e. This position is in Fig. 5 shown. In this position, the output of the electric motor 1m is already back to its starting position scaled back. In this position, the distance a results between the output 1ma of the electric motor 1m and the spring plate 1ft of the detected by the blocking device 1e compressed clutch spring 1f. Starting from this position, the first push rod 1a is moved during actuation of the push rod 1 without that the coupled with the lock second push rod 1b is moved for a lock operation. By triggering the electromechanical locking of the blocking 1e, the clutch spring 1f relaxes in its preloaded initial position to form a coupling of the two push rods 1a, 1b. If now the push rod 1 of the actuating handle is actuated, the first push rod 1a is moved in the illustration in the figures to the right, while the connected to the lock nut 20n second push rod 1b taken in this direction under unlocking the lock 20. So as soon as the clutch spring 1f in the charged position of Fig. 5 is blocked and the output of the motor 1m in its initial position, as in Fig. 5 is shown, is retracted, the actuating handle with its push rod 1 is ready. For this purpose, the separate coupling element 1k is decoupled, as in Fig. 5 is shown.

The coupling element 1k is provided for the case that an authorized person by pressing the push rod 1 actuate the lock, ie wants to unlock. For this case, the coupling element 1k is connected via the access control device, not shown, or optionally via a key in the coupling position, in which the coupling element 1k the first push rod 1a coupled to the second push rod 1b. This clutch via the coupling element 1k is also turned on as long as the clutch spring 1f is charged via the engine 1e. Since this additional coupling device 1k assumes no safety functions, a electrical control of the coupling device 1k also be carried out according to the working current principle or motor.

In order to ensure an automatic control of the safety function in case of panic even with a controlled push rod, it can be provided that the push rod 1 and the actuating handle 10 is also equipped with a switching element which triggers the emergency switch function upon actuation of the push rod 1. For this purpose, a switching element with the function of a conventional emergency stop button in the region of the push rod 1 or integrated in the actuating handle 10 can be arranged. In order for an authorized operation of the actuating handle 10 does not trigger this emergency switch, it can be provided that this is arranged between the two push rods, so that it is actuated only with a corresponding relative movement of the two push rods 1a, 1b. The switch may preferably be designed such that it actuates the blocking device 1e only after a time delay after it has been actuated by the push-rod actuation, in order to thus couple the push rods 1a, 1b via the clutch spring 1f in a time-delayed manner. Instead of the emergency switch integrated in the actuating handle 10, an emergency stop button can also be mounted outside the actuating handle in a conventional manner, which switches the blocking device 1e.

In order to unlock the lock 20 also remotely controlled, is in the modified embodiment in FIG. 6 the push rod 1ü provided. The motor 1m is arranged so that it drives the push rod 1b or directly the lock nut 20n in the sense of a motor unlocking of the lock 20 in a movement against the Aufladerichtung the spring 1f.

At the in FIG. 7 shown further embodiments is an actuating handle 10 with push rod 1. The push rod 1 is guided in a linear guide 1l of the storage rack perpendicular to the door leaf level. The adjusting movement in the actuation of the push rod 1 is transmitted via a link mechanism on push rods 1a, 1b, which are guided in the base plate of the storage rack parallel to the door leaf plane linearly displaceable. The push rod 1b is connected to the in FIG. 7 not shown door lock coupled via a square nut 10n. The door lock may preferably be mounted as a mortise lock in the door leaf with the locknut in alignment with the square nut 10n. The first push rod 1a, which is coupled in a gear-wise manner with the push rod 1, can be coupled with the second push rod 1b coupled to the lock via a compression spring 1f in a corresponding manner as explained in the above-described exemplary embodiment. For charging the clutch spring 1f, an electric motor 1m is also provided. This is arranged in the storage rack of the actuating handle device 10 below the push rod 1. The motor 1m has a spindle nut output 1ma, which cooperates for charging the clutch spring 1f with the clutch spring 1f supported on the first push rod 1a. This in FIG. 7 illustrated embodiment of the push rod actuating handle 10 is thus constructed in accordance with the embodiment described above. It also works accordingly.

at FIG. 8 it is an embodiment in which only the coupling device 1 k compared to the embodiment of FIGS. 3 to 5 modified. The coupling device 1k points in FIG. 8 a pivotally mounted pawl 1kk on the with a solenoid 1km and a spring 1kf interacts. The pawl 1kk cooperates with a rack 1kz which is fixedly arranged on the second transmission element 1b. The latch device 1k is arranged on the first transmission element 1a. The spring acts on the pawl in engagement with the rack, the electromagnet acts on the pawl 1kk in engagement with the rack 1kz. The pawl 1kk is designed as a one-armed lever, on whose lever arm the spring 1kf and the electromagnet 1km attack in parallel. The electromagnet 1km and the spring 1kf are supported with their bearing end on the first transmission element 1a. The rack is disposed along the longitudinal direction of the unlocking movement of the second transfer member 1b. The teeth of the rack are formed as saw teeth and arranged so that upon engagement of the pawl 1kk is locked in the rack, a movement of the transmission element 1 b in the unlocking direction.

This pawl device with the Zahnstage provides a mechanical coupling of the first transmission element 1a with the second transmission element 1b in a corresponding manner as in the in the FIGS. 3 to 5 shown embodiments. However, in FIG. 8 the engagement of the pawl 1kk can take place in different positions of the position of the transmission element 1b or relative to the transmission element 1a. The latch engagement is not only in the initial position of the actuating handle, but also when the actuator is already operated and unlocking is not sufficient by the energy stored in the clutch spring 1f. In this case, different positions are realized in the rack, depending on the successful Entriegelungshub the second transmission element 1b. The others Unlocking then takes place by actuation of the handle when coupled via the latch device 1k transmission elements 1a and 1b.

Since the rack is designed as a sawtooth, the spring force can be effective for unlocking once the lock of the lock is overcome by manual operation with mechanical coupling.

At the in FIG. 9 illustrated embodiment is provided in a modification of the embodiment described in the preceding figures, only an additional connection means 1fv. Incidentally, the embodiment is unchanged. This connection device 1fv is effective upon release of the blocking device 1e and prevents the clutch spring 1f from being compressed by the first transmission element 1a or the first push rod 1a.

The connecting device 1fv is arranged parallel to the clutch spring 1f. It is supported with its one end on the motor-side spring bearing and with its other end to the spring bearing of the second transmission element 1 b and thus connects the first transmission element 1 a to the second transmission element 1 b. It is designed as a telescopic ball clamping device, which locks in Federeinfahrrichtung, ie continuously in the compression direction of the spring. In the spring extension direction, ie in the direction of expansion, the connecting device 1fv is ineffective in order to ensure unimpeded unlocking of the door lock 20. The connecting device 1fv is switchable. When charging of the clutch spring 1f takes place via the electric motor 1m, the connector 1fv is inactivated to allow the compression of the clutch spring 1f via the electric motor.

• Bei Weg 1 ist das zweite Übertragungselement 1b mit der vom Elektromotor 1m aufgeladenen Kupplungsfeder 1f gekuppelt, um das Schloss 20 durch die Entladung der in der Kupplungsfeder 1f gespeicherten Energie zu entriegeln. Dabei ist das zweite Übertragungselement 1b von dem ersten Übertragungselement 1a entkuppelt.
• Bei Weg 2 ist das zweite Übertragungselement 1b mit dem ersten Übertragungselement 1a gekuppelt, um das Schloss 20 über eine manuelle Betätigung des ersten Übertragungselements 1a mittels der Handhabe 1 zu entriegeln. Dabei ist die Kupplungsfeder 1f von dem gehäusefest abgestützten Lager 1ml entkuppelt.

That in the FIGS. 10a to 10c illustrated embodiment differs from those in the FIGS. 3 to 5 shown embodiment only in that the motor 1m has a bearing solidly supported bearing 1ml. This bearing 1ml is pivotable by means of an actuator 1hl designed as an electric solenoid or electric motor and is controlled by a preferably electric control device. The unlocking of the lock 20 takes place in this embodiment, two alternative ways 1 and 2:

• In path 1, the second transmission element 1b is coupled with the clutch spring 1f charged by the electric motor 1m to unlock the lock 20 by discharging the energy stored in the clutch spring 1f. In this case, the second transmission element 1 b is decoupled from the first transmission element 1 a.
• In path 2, the second transmission element 1b is coupled to the first transmission element 1a to unlock the lock 20 via a manual operation of the first transmission element 1a by means of the handle 1. The clutch spring 1f is decoupled from the bearing 1ml supported on the housing.

The uncoupling of the clutch spring 1f supported by the bearing 1ml fixed to the housing takes place in the illustrated embodiment in that the bearing 1ml pivots out of the range of movement of the spring 1f when released blocking device 1e connected to the handle 1 first transmission element 1a is not actuated, ie a Person does not operate the handle 1, the handle 1 is thus in its normal position unconfirmed. By swiveling away the bearing 1ml is avoided that the Clutch spring 1f unlocks the door lock 20 when the transmission element 1a is not yet actuated and therefore there is no actuation of the handle 1 by a person at the relevant time. For this purpose, the handle 1 may be connected to a detection device which monitors the handle to a manual operation. The detection device can be designed as a substantially electrical device, but also as a purely mechanical device. The coupling of the first transmission element 1 a with the second transmission element 1 b through the coupling device 1 k ensures that an unlocking of the door lock during actuation of the first transmission element 1 a thus takes place manually via the handle 1. The control device ensures that the swinging out of the housing-fixed bearing 1ml takes place only after a successful coupling of the coupling device 1k.
