Abstract

The lock (1) has a lock mechanism controlling a latch bolt (8) or a bar (7) and an actuating handle (9) which is coupled with the lock mechanism for actuating the latch bolt or the bar by a pre-loaded spring (15). The pre-loaded spring is charged by the actuation of the actuating handle. The actuating handle is coupled directly with the actuation mechanism by renewed actuation after loading the preloaded spring and subsequent release of the energy that is stored in the preloaded spring for actuating the locking mechanism in the context of opening the arrested locking mechanism.

Description

The invention relates to a lock according to claim 1.

From the DE 30 32 086 A1 is a panic lock with a lock latch and / or a lock bolt controlling locking device known. An inner handle allows in case of panic, to operate the locking device in the opening direction. By means of a changeover device, which consists of a remotely controllable, electrically, pneumatically or hydraulically acting switching element, the panic function of the locking device can be temporarily switched off.

The DE 43 40 537 C2 discloses a panic lock operable by a key and / or by an actuating handle with split pusher, change, tumbler, latch and latch bolts arranged in a latch housing. An additional trap arranged between the latch bolt and the latch, like the latch and the latch bolt, protrudes against the restoring force of a spring element from an opening in the cuff. The additional case is guided in a longitudinal slot on the lock housing bottom and controls a likewise arranged in the lock housing automatic locking, which locks the latch and the latch bolt with the door closed against pushing back. By an electrical switching pulse an actuating handle for unlocking can be coupled.

The disadvantage is the panic function of the locks given only from one side of the lock.

The invention has for its object to further improve a panic lock.

The object is solved by the features of claim 1.

The lock according to the invention comprises a lock mechanism which fulfills the panic function, ie that by actuating an actuating handle, for example a pusher or a panic bar, both the latch and the latch are retracted into the lock to allow opening of the previously securely locked door.

The lock also has an arrangement for releasing or blocking the door opening, which can be electrically actuated. This makes it possible to prevent unauthorized opening of the door, but to ensure opening of the door in case of danger. The release can be done automatically, for example, by a fire alarm, as can be detected by a smoke detector, or due to a power failure, when the release device operates on the quiescent current principle, the release is disabled, as long as the operating voltage is present. The release can also be done centrally, for example by an operator in a gate, or by pressing an emergency button to open the door. The emergency button is advantageously arranged on or near the door.

It is also an application in connection with an access control device possible, the door can be opened when authorized.

Between the actuating handle and the lock mechanism of the castle to a split pusher nut is arranged. So that advantageously unlocking takes place even if the actuating handle is already operated before the release, an energy storage is provided, which caches the energy introduced by the operation until release at least until the actuation handle is released again.

It is envisaged that the lock for one-sided walking, for example in the direction of escape at a door in escape and rescue routes, or for a two-sided walking, for example, in conjunction with the access control device form. For walking on both sides, a three-piece pusher may be provided, each having a pusher disc for each of the actuating handles. This makes it possible to control the ascent from both sides of the door. In particular, in a door in escape and rescue routes, which is provided with a panic bar, it is advantageous that the lock is released when already activated panic bar, since a loosening and re-pressing the panic bar may not be possible due nachdrängender persons.

In a further embodiment, the lock may comprise a release drive which operates on the working current principle, i. to release the lock, the drive means, e.g. an electromagnet, energized. In the non-energized starting position, the lock is locked. The control device may be connected to a fire or smoke detection device to release the lock in case of danger, as may be provided in doors in escape and rescue routes.

It can also be a remote control for visitors, for example, from a gate, done, or it may be an electronic access control system connected to the drive device. Furthermore, a switch can be provided in the lock, which switches even with slight pressure on the actuating handle and thus activates the drive means for releasing the lock.

Alternatively, the drive device can also operate according to the quiescent current principle. The lock is locked when the drive means, e.g. the electromagnet is energized. This is advantageous because, when used on a door in escape and rescue routes, the door will automatically release in the event of a power failure for safety. Also in this embodiment, a switch may be provided, which is here, however, designed as an opener and interrupts the current through the electromagnet to release the lock upon actuation of the actuating handle.

In a further development, the control device may have an arrangement with two electromagnets, which can be selected by means of a selector switch between a mode of operation according to the closed-circuit principle or the working current principle. The selector switch can be designed so that the electrical switching is effected from one to the other electromagnet.

In a further alternative embodiment of the lock, the electromagnet can be arranged outside the lock in the strike plate of the door, whereby advantageously no lines on the door leaf for the signal and power supply are required. In this case, the electromagnet acts directly on his arranged in the area opposite the cuff in the lock armature, which in turn is designed to release the lock, to which the armature cooperates with a trigger that releases a rocker switch in the lock.

The rocker switch can be arranged to be adjustable by means of a selector switch, whereby it is possible to assign the switching rocker of the desired trigger plate and thus the associated actuating handle in a version with a three-piece follower. The release by the switching rocker can be done independently of the release by the solenoid directly through the trigger plate by the actuating handle. There is also the possibility to put the rocker switch in a middle position between the handle plates, whereby the release of the lock by the actuating handle is no longer possible.

In addition, a damping device can also be provided, which dampens the pivoting movement of the pusher disc, as a result of which the withdrawal of the latch and the latch takes place with low noise.

Another embodiment of the lock has a device for bridging the storage spring, which advantageously allows for a jamming of the lock, for example, due to damage or by wind pressure, opening the door. Since limited by the memory spring, the force that is available to operate the lock, the actuating handle can be rigidly connected by means of this device with the trigger lever, whereby the force introduced at the actuating handle directly bypassing the memory spring on the bolt and the latch can act. The device for bridging the storage spring is designed so that the direct coupling is effected by catching up with the actuating handle, ie by briefly releasing and repressing the actuating handle.

In a further embodiment of the lock, a time delay for opening the lock and / or an alarm device can be provided. Both the time delay and the alarm device inside the lock are purely mechanical, so that no wiring for electrical control and / or power supply lines on the wing of the door is required. If the lock is actuated to the door opening by means of the actuating handle, the alarm device can effect a signal output, for example an alarm siren, whereby a person who wishes to use the door without authorization can be deterred. It will also alert people in the area. It is also possible to send a signal to a central monitoring device, e.g. in a wicket, which allows guards to be informed.

Simultaneously with an alarm, the time delay can be started by depressing the actuating handle. The time delay causes the lock to open delayed after a certain alarm time.

The different variants can also be partially or completely combined with each other.

The subclaims form advantageous embodiments of the invention.

In the following, exemplary embodiments are explained in more detail in the drawing with reference to FIGS.

In Fig. 1 an inventive lock 1 is shown in side view, with a housing 2 and a cuff 3, with which the lock 1 in a conventional manner in a lock pocket of a door leaf can be fixed. The housing 2 is shown open and essentially comprises a lock mechanism with a latch mechanism 5, which fulfills the panic function and upon actuation of the lock 1 by an actuating handle 9, which is designed here as a pusher, the latch 7 of the burglar resistant lockable via a lock cylinder 6 door withdraws. The retraction of bolt 7 and 8 case is also possible by actuation of the lock cylinder 6 via a mechanism not shown here. The actuating handle 9 is shown in phantom in the figures to show the underlying parts. The lock mechanism further comprises a latch 8, which also cooperates with the actuating handle 9. The latch 7 and the latch 8 engage in the excluded state in a strike plate 4, which is arranged in a known manner to the door frame or double-leaf doors on the opposite door leaf.

Between the actuating handle 9 and the locking mechanism 5, a split pusher 10 is arranged. The pusher 10 comprises a pusher disc 11 and a pusher lever 12, which lie in the pivot axis of the actuating handle 9, and which are arranged rotatably relative to each other. The pusher disc 11 and the pusher lever 12 are in the FIGS. 3 and 4 shown as a single item.

On the trigger plate 11, a receptacle 13 for receiving a not shown here, usually designed as a square mandrel of the actuating handle 9 rotatably disposed, whereby the pivoting of the actuating handle 9, the pusher disc 11 rotates in the pivoting direction of the pusher 9 with. The pusher disc 11 is supported for returning the actuating handle 9 in its horizontal starting position with an extension 22 on a return spring 14, which, not shown here in detail, is supported at the other end in the housing 2. In the housing 2, a stop 23 is provided for the extension 22 in order to determine this horizontal starting position of the actuating handle 9.

The trigger lever 12 comprises two lever arms 12.1, 12.2, wherein the first lever arm 12.1 of the trigger lever 12 cooperates with the latch 8. The case 8 has a guide 24 into which a pin 25 for guiding the latch 8 engages. The case 8 is further supported on a spring 26 against the lever arm 12.1, whereby a pushing back of the case 8 is possible, as is required when closing the door leaf. A pivoting of the trigger lever 12 with the lever arm 12.1 causes a retraction of the case 8 in the housing 2 of the lock 1 in, whereby the case 8 is disengaged from the strike plate 4.

The second lever arm 12.2 engages in the latch mechanism 5 actuated. The structure of the locking mechanism 5 is hereby arbitrary and therefore not further illustrated. By pivoting the trigger lever 12 with the engaging in the latch mechanism 5 lever arm 12.2 the retraction of the bolt 7 is triggered in the housing 2 into it, and the latch 7 is disengaged from the strike plate 4. At the trigger lever 12 is still an extension 22 'provided in the starting position also comes into contact with the stop 23. The return to the starting position can be done due to restoring forces of the locking mechanism 5 and / or by the return spring 14, which act on the lever arm 12.2 of the trigger lever 12.

The lock 1 has an arrangement for releasing or blocking the door opening, which can be electrically actuated in order to prevent unauthorized opening of the door, but to allow opening of the door in the event of danger.

Advantageously, an emergency button can be arranged on or near the door to release. Additionally or alternatively, the release can be done automatically, for example by a fire alarm, as it can be detected by a smoke detector. If the release device operates on the quiescent current principle, wherein the release is disabled, as long as the operating voltage is present, advantageously takes place a release automatically in case of power failure. Furthermore, the release can also be done centrally, for example by an operator in a gate, or by an access control device, for example in conjunction with a card reader or the like.

The release device comprises a nose 21 provided on the trigger lever 12, which nose cooperates with a shoulder on a release lever 18. Alternatively, a notch in the trigger lever 12 may be provided for engagement of the trigger lever 18. The release lever 18 is rotatably mounted in a bearing 20 and received in a trigger 19 when no release is given. In Fig. 1 the locked position is shown, wherein the trigger lever 12 is locked by the release device against rotation.

To couple the split pusher 10, a memory spring 15 is disposed between the pusher disc 11 and the pusher lever 12. The memory spring 15 is partially received in a recess 16 of the pusher disc 11 and in a recess 17 of the pusher lever 12, as in the partial section, along the line II - II in Fig. 1 through the pusher disc 11 and the pusher lever 12 in Fig. 2 is shown. The recess 16 can pass through the pusher disk 11 completely or can only be formed as a recess in the pusher disk 11. Also, the recess 17 may be formed in the handle lever 12 as a depression or the lever lever 12 by cross. As a memory spring 15, in addition to the coil spring shown in the figures in a similar arrangement with the same effect, for example, a spiral, leaf or leg spring used become. Also, the return spring 14 may be formed accordingly. Elastomers are also applicable as spring elements. Alternatively, only one of the recesses 16, 17 may be provided, in which case a driver is provided on the pusher disc 11 or the pusher lever 12, which cooperates with the accumulator spring 15, which is advantageous in particular when using a spiral spring. In a further embodiment, the memory spring 15 can be arranged externally around the pusher disk 11 and / or the pusher lever 12, at least partially encompassing it. Also conceivable is an arrangement of a leaf spring which is fixed in each case at the end to the pusher disc 11 and the pusher lever 12.

In Fig. 5 the lock 1 is shown with pressed actuating handle 9, wherein no release of the lock 1 is given. The rotatably connected to the actuating handle 9 via the receptacle 13 Drückerscheibe 11 is against the return spring 14 in the clockwise direction in the in the Fig. 5 shown rotated position. Due to the partial arrangement of the accumulator spring 15 both in the recess 16 of the pusher disc 11 and in the recess 17 of the pusher lever 12, the accumulator spring 15 is compressed by the rotation of the pusher disc 11, since the pusher lever 12 is locked against rotation by the nose 21st supported on the release lever 18. The initiated by the actuation of the actuating handle 9 to open the door energy is thus initially stored in the memory spring 15.

The release of the lock 1 to the door opening takes place when actuated actuating handle by the trigger 19 in the Fig. 6 pivots counterclockwise. This can be effected for example by switching off an electromagnet, which is not shown here in detail in the figure. Thus, the pivotally mounted about the bearing 20 release lever 18 is released and lifted by the nose 21 of the memory spring 15 in the clockwise direction press lever 12. Due to the now possible rotational movement of the trigger lever 12, the lever arm 12.1 pushes the case 8 into the housing 2 of the lock 1, and the lever arm 12.2 actuates the locking mechanism 5 in a manner not shown here, whereby the conclusion of the lock 7 in the housing 2 inside he follows. Since now both the latch 7 and the case 8 are retracted, the door can be opened.

The provision of the trigger lever 18 in its initial position, wherein this is received in the trigger 19, carried by the nose 21 in reverse rotation of the trigger lever 12th

Also conceivable is a three-part pusher 10, wherein each one pusher disc 11, 11 disposed on both sides of the pusher lever 12 with the respective associated return springs 14, 14 'and memory springs 15 and each having an associated actuating handle 9 are connected, as in Fig. 7 is shown. As a result, control of the ascent from both sides of the door is possible, for example in connection with an access control, whereby an associated release lever 18 with trigger 19 can be provided in each case.

In the 8 to 11 Further embodiments are shown, wherein the lock 1 has a drive 27 for the release. In the 8 and 9 a control device 27 is shown, which operates on the working current principle, wherein an electromagnet 28 is energized to release the lock 1. The electromagnet 28 has a pivotably mounted armature 29, which is acted upon by a spring 30 to return the armature 29 after switching off the current in the starting position. At the armature 29 of the already described trigger 19 is arranged or formed integrally therewith. In the non-energized initial position, the lock 1 is locked, as already mentioned above to the Fig. 1 to 5 is described, wherein the trigger lever 18 is received in the trigger 19.

When the electromagnet is energized, the magnet armature 29 is pivoted with the trigger 19, and the release lever 18 is released, as in Fig. 9 is shown. The energization of the electromagnet 28 may be effected in different ways. Thus, the solenoid 28 may be connected to a fire or smoke detection device, whereby the lock 1 is released in case of danger, as may be provided in doors in escape and rescue routes. It can also be a remote control for visitor guidance, for example from a Gate, done, or it may be an electronic access control system connected to the control device 27. In conjunction with the aforementioned devices or alone, a switch 31 may be provided which is already actuated with slight pressure on the actuating handle 9 and thus acts on the electromagnet 28. This can take place by means of a contour formed on the pusher disk 11, 11 ', which controls the switch 31 designed as a microswitch. The switch 31 can also be designed as a reed contact switch, wherein an associated magnet can be arranged on or in the pusher disc, which cooperates with the reed contact switch.

With pressed actuating handle 9, the inference of the bolt 7 and the collection of the case 8 is now effected. If the actuation of the actuating handle 9 only after the release of the lock 1 by the energization of the electromagnet 28, by the then already released coupling of pusher disc 11, 11 'and trigger lever 12 of the conclusion of the bolt 7 and the collection of the case 8 directly through the Actuation effected.

In the 10 and 11 a control device 27 is shown, which operates on the quiescent current principle. In this case, the lock 1 is locked when the solenoid 28 is energized. This is advantageous because when used in a door in escape and rescue routes, the door will automatically release in case of power failure for safety. In Fig. 10 is the pivotally mounted, formed from two lever arm magnet armature 29 is tightened, whereby the trigger 19 secures the release lever 18 against pivoting. If the power supply of the electromagnet 28 is interrupted, the armature 29 is pivoted by the spring 30, whereby the release lever 18 passes from the receptacle of the trigger 19 and is released, as in Fig. 11 is shown. Also in this embodiment, a switch 31 may be provided, which is designed here as an opener and interrupts the current through the electromagnet 28 to release when actuated. It is conceivable another, external switch, which corresponds to the switch 31, whereby the function of the switch 31 controllable and a configuration of the castle is possible.

The magnet armature 29, the trigger 19, which is supported against a spring 42, pivotally mounted. This ensures that the trigger lever 18 regardless of the position of the magnet armature 29 can engage in the trigger 19 when the release lever 18 by relieving the actuating handle 9 and the turning back of the trigger lever 12 by the return spring 14, 14 'with the nose 21 in its locking position is pivoted.

In the FIGS. 12 and 13 an arrangement with two at an angle to each other arranged electromagnets 28, 28 'is shown, which can be selected by means of a selector switch 32 between a mode of operation according to the quiescent current principle or the working current principle. With the rotatable selector switch 32, the articulation of the spring 30 is variable, so that one of the here at least approximately perpendicular to each other arranged lever arms of the armature 29 is acted upon either in the direction of the electromagnet 28 or the electromagnet 28 '. The selector switch 32 can simultaneously cause the electrical switching from one to the other electromagnets 28, 28 '.

In the FIGS. 14 and 15 a further embodiment is shown, wherein at least one of the electromagnets 28, 28 'is outside the lock 1 in the strike plate 4 of the door. The magnet armature 29 is located opposite the electromagnet 28 directly in the region of the cuff 3. The magnet armature 29, in turn, the trigger 19 is pivotally loaded with a spring 42, arranged. This embodiment further comprises a selector switch 33, which cooperates with a switching rocker 34, which is designed as a pivotally mounted, two-armed lever. A first lever arm cooperates with the trigger 19, while the second lever arm with the pusher disc 11, 11 ', cooperates, which is formed as a cam plate, through which the rocker switch 34 against a spring 35 is pivotable. Furthermore, an extension 40 is arranged on the rocker switch 34, which engages in a spindle 41 of the selector switch 33. By turning the selector switch 33 is the extension 40 of the rocker switch 34 - and thus the rocker switch 34 itself - along the spindle 41 in its position with respect to the pusher disc 11, 11 'adjustable. This makes it possible, in an embodiment of a lock 1 with a three-piece follower, as it is Fig. 7 is described, the triggering of the trigger 19 alternatively the pusher disc 11 or the pusher disc 11 'and thus associated with the associated actuating handle 9. The release by the rocker switch 34 takes place independently of the release by the solenoid 28 directly via the pusher disc 11, 11 'by the actuating handle 9. Another possibility is the rocker switch 34 in a position outside the range of the pusher discs 11, 11' , For example, a middle position between the pusher discs 11 and 11 ', set, whereby no release of the lock 1 by one of the actuating handle 9 is more possible.

In Fig. 14 Furthermore, a damping device 36 is shown, which dampens the pivoting movement of the pusher disc 12, whereby the retraction of the bolt 7 and the case 8 is quiet. In a cylinder 38 to a piston 37 is guided, which has a piston rod 39 which is sealingly guided by an end wall of the cylinder 38. The piston rod 38 is connected to the trigger lever 12 and engages the lever arm 12.2. Alternatively, the piston rod 39 can also engage in the region of the lever arm 12.1 or otherwise on the trigger lever 12. The damping device 36 is position-independent and can for example also be arranged vertically.

The FIGS. 16 and 17 If the lock 1, for example, due to damage or wind pressure, clamp, so it is possible by this device, the actuating handle 9 rigidly connected to the trigger lever 12, whereby the force applied to the actuating handle 9 can act directly on the latch 7 and the latch 8. For this purpose, the pusher disc 11, 11 'and the pusher lever 12 of the split pusher 10 can be locked in their rotational mobility to each other.

If the actuating handle 9 is pressed, the memory spring 15 is initially loaded in the manner described above, which can be released by the control device 27 for opening. Is not possible for the reasons mentioned above despite the release, because the spring force of the accumulator spring 15 is not is sufficient to withdraw the latch 7 or the case 8, the bridging of the accumulator spring 15 can be effected by tracking with the actuating handle 9.

The device for bridging the storage spring 15 is formed by means of a spring 45 acted upon, pivotally arranged lock 44. The lock 44 is disposed in the pusher disc 11, 11 'and engages in a guide 47 of the pusher lever 12 a. The application of the lock 44 by the spring 45 is directed outwards, ie away from the center of the pusher disc 12. In the locked state of the lock 1, wherein the release lever 18 is received in the trigger 19, the lock 44 is held down by a arranged on the release lever 18 slider 43 against the force of the spring 45. If the actuating handle 9 is pressed, the lock 44 can move in the guide 47, for which the lock 44 is stepped in the region of the guide 47, as it is in Fig. 19 is shown. In Fig. 19 the lock 44 is shown cut in the plane of the trigger lever 12.

If the lock 1 is released by the drive device 27, the lock 44 can not initially pivot outward, since, when the actuation handle 9 is pressed, the lock 44 is in the narrow region of the guide 47 - in the FIG. 19 is received in the right area of the guide 47-. If the latch 7 or the case 8 is not withdrawn now, since the spring force of the accumulator spring 15 is insufficient, can be followed with the actuating handle 9, ie the actuating handle 9 is released, thereby close to the starting position of the actuating handle 9, the lock 44 in the extended Area left of the nose 46 can swing in the guide 47. The lock 44 now passes, due to the spring 45 designed as a leg spring, behind the nose 46 on the trigger lever 12. Several lugs 46 can be arranged in a stepped manner, which makes it possible to follow up with the actuating handle 9 in several steps.

A renewed depression of the actuating handle 9 causes by this engagement of the lock 44 on the nose 46 that the pusher disc 11, 11 'under Exclusion of the memory spring 15 is directly connected to the trigger lever 12, that is coupled. The force of the actuating handle 9 is thus introduced directly via the pusher disc 11, 11 ', the lock 44 and the nose 46 on the trigger lever 12, which can withdraw the latch 8 and the bolt 7 with the lever arm 12.1 and 12.2. It is further arranged a pin 48 which is provided to pivot the lock 44 when releasing the actuating handle 9 against the spring 45 inwardly toward the center of the pusher disc 11, 11 'back. After locking the lock 1 by the drive device 27, the lock 44 is again held down by the slider 43, whereby the pusher disc 11, 11 'and the trigger lever 12 are decoupled and actuation of the actuating handle 9 again causes a charging of the accumulator spring 15.

In the FIGS. 20 and 21 a further embodiment of the lock 1 is shown, wherein a time delay 49 for the opening of the lock 1 and an alarm device 50 are provided, whereby a pre-alarm before opening is possible. Both the time delay 49 and the alarm device 50 are formed purely mechanically within the lock 1, so that no wiring of electrical control and / or power supply lines on the wing of the door is required. However, it is also an external arrangement for electronic time delay conceivable. If the lock 1 is actuated to open the door by means of the actuating handle 9, a signal output can be effected by the alarm device 50. This may be, for example, an alarm siren, which may possibly deter a person wishing to use the door without authorization, or even trigger a signal on a monitoring device in a gate, thereby informing security guards.

For this purpose, the alarm device 50 has, in the lock 1, a magnet 52 displaceably displaced against a spring 51, which cooperates with a magnetic field sensor 53, for example a reed contact or a Hall element, which can be arranged on the frame side in the strike plate 4. The spring 51 and the magnet 52 is guided in a fixed in the lock 1 sleeve 54. The magnet 52 is connected to a pull rod 55 which has at its end a pulling head 56, which in the rest position of the actuating handle 9 on an extension 57 of the pusher disc 11, 11 'is applied, whereby the magnet 52 is displaced away from the cuff 3 against the force of the spring 51 and the magnetic field sensor 53 is not activated.

Swivels the extension 57 of the pusher disc 11, 11 'due to an actuation of the actuating handle 9 in a clockwise direction, as shown in the Fig. 21 is shown, the magnet 52 is displaced by the spring 51 in the direction of the cuff 3, whereby the magnetic field sensor 53 is activated for signal output.

Simultaneously with this alarm is triggered by the actuation of the actuating handle 9, the time delay 49, which serves to open the lock 1 time-delayed to initially output before opening for a certain time the alarm. For this purpose, it is provided that the time delay 49 delays the stored energy in the memory spring 15 after pressing the actuating handle 9 in the lock mechanism. The purely mechanical time delay 49 consists of a damping element with a displaceably arranged in a cylinder 58 piston 59, on which a pull rod 60 is arranged. The pull rod 60 has at its end also a pulling head 56 which cooperates with the extension 57 of the pusher disc 11, 11 '. On the pull rod 60, a driver 61 is further arranged, which cooperates with a suitably designed rocker switch 34. It can also find alternative damping elements application.

If the actuating handle 9 is pressed and thus the extension 57 of the pusher disc 11, 11 'pivoted in the direction of the cuff 3, the acted upon by the spring 62 piston 59 is also displaced in the cylinder 58 in the direction of the cuff 3. The piston 59 is guided with a slight gap to the inner wall of the cylinder, whereby a damping of the sliding movement of the piston 59 is caused due to the forced thereby slow overflow of air from one side of the piston to the other side of the piston in the cylinder 58, including a bore or a valve in the Piston 59 may be provided. It can also be a different damping medium than the ambient air, eg oil, may be provided. By the sliding movement of the piston 59 and the pull rod 60 passes the driver 61 after a certain time in contact with the rocker 34 and pivots it clockwise. As a result, the trigger 19 is actuated, and the trigger lever 18 is released, which now time-delayed against the operation of the actuating handle 9, the lock 1 is released and the latch 7 and the case 8 are retracted.

Upon release of the actuating handle 9, the pivoting back of the extension 57 of the pusher disc 11, 11 'is effected by the return spring 14. As a result, the extension 54 comes into contact with the traction heads 56 of the pull rod 55 of the alarm device 50 and the pull rod 60 of the time delay 49, whereby the magnet 52 and the piston 59 are each moved back to their original position.

It may be provided in the piston 59 of the time delay 49 to a valve assembly that allows a slight push back into the starting position with unconfirmed actuating handle 9 by a larger opening in the piston 59 is released.

At the same time the driver 61 on the pull rod 60 is disengaged from the switching rocker 34, whereby the re-locking of the lock 1 is made possible by engagement of the release lever 18 in the trigger 19.

Of course, the variants shown in the various embodiments can also be combined with each other.
