EP3628801B1 - Lock device for a door and a method for opening a door - Google Patents

Description

The present invention relates to a lock device for a door such as a security door or the like. Doors of this type typically have two leaves, namely a (lockable) inactive leaf and an active leaf, in particular a movable leaf that releases a door opening.

In the case of locks for such doors, an inactive leaf lock part usually has a latch entry opening and possibly a bolt entry opening. These interact with a latch and a bolt of an active leaf lock part of the active leaf. Both latch and bolt can be moved back into the active leaf lock part by applying a counterforce.

Known lock devices are also equipped with a panic function, the handle of which is assigned in particular to the inactive leaf lock part. This lock part therefore typically has a latch ejector or latch slide and a bolt ejector or bolt slide, with which the latch and the bolt can be pushed out of the corresponding entry openings by manually operating a push rod or some other panic handle. Improvements to such locks usually have electric door openers in the first lock part in the passive leaf, which - for example with the aid of a remote control at a distance from the door - can provide electrical opening.

Such a lock device is for example from DE 199 57 999 B4 known. In the first part of the lock, a swivel shutter is rotatably mounted there, which forms a blocking wall on which the blocking flank of the latch is basically supported. The swivel drawer can however, they can be released with the aid of an electromechanical actuator. Since with such a device, however, no conventional trap ejector or trap slide can be provided for the trap, the patent mentioned discloses the solution of providing an additional manual actuation of the swivel drawer so that the trap does not have to step back when the panic function is actuated, as this too the swivel drawer is released.

A slightly different approach in this regard is chosen by the device, which from the DE 10 2005 015 248 B4 is known. An electric door opener is also provided there. When the panic function is activated, however, the door latch is exposed from an entry opening of the first lock part, namely by a plunger integrated into the electric door opener, which contacts the end face of the door latch and pushes it out of the entry opening.

Both solutions known from the prior art, however, have the disadvantage that very special electric door openers have to be manufactured or used for this purpose. In particular, standard door openers cannot be used.

The object of the present invention is therefore to provide a lock device which enables a more universal use, for example the use of conventional door openers, if this is desired.

The invention solves this problem with the features of claim 1 and is therefore characterized in that the second lock part has an auxiliary latch in addition to the lock latch and the lock bolt, and that the manual operation can be geared to a pulling mechanism or (with the door closed) is coupled, with which the head of the lock latch can be pulled out of the inlet opening and which provides said auxiliary latch to overcome the gap between the first and second lock parts.

In other words, the invention solves the problem in that the area of the (first) lock part in which the head of the lock latch is (when the door is closed) is not acted on (as in the prior art), but rather the head of the lock latch is shifted rather indirectly, namely by pulling the head in the direction of the second lock part, in particular from the second lock part.

In the prior art described, in the event of a panic, instead, either the swivel shutter is released manually or the head of the lock latch is acted on directly, namely with the described plunger, which leads to an immediate application of pressure to the head.

In contrast, the chain of action runs from manual actuation to the lock latch head according to the present invention not directly (only) through the first lock part, but rather via a slight detour, in particular via the second lock part, further in particular via the lock latch body. This enables the use of a conventional electric door opener, which neither has to have a mechanical actuation for the swivel drawer nor a separate plunger.

A comparable chain of effects is already from the DE 25 46 549 A1 known, but not there in connection with an electric door opener. In this prior art, the gap between the two door leaves is provided via a pivotable latch on the one hand and a linearly displaceable (liftable) lever on the other, which both protrude over the respective door faceplates and thus protrude into the gap between the two door leaves in every position. The solution shown there is completely impractical in that the gap between the door leaves cannot be minimized at all and a certain offset of the two door leaves against each other could already disable this mechanism.

According to the invention, the head of the lock latch can therefore be pulled out of the inlet opening. This leads to the door opening, especially in the event of a panic.

In contrast to the prior art, in which the head of the lock latch is pressed, this is pulled according to the invention, for example by attacking the body of the lock latch (the lock latch encompassing both the body and the head). In other words, the body of the latch can be pushed. According to the invention, however, this always leads to a pulling (pulling out) of the head of the lock latch (from the entry opening).

For this purpose, according to the invention, a pulling mechanism is provided, for example in the manner of a gear or the like. This pulling mechanism can have components in both lock parts (or preferably only in the active leaf lock part) and in particular form or at least partially provide an operative chain from the actuation to the lock latch (or its head).

The special feature here is typically that this chain of action (in particular also the pulling mechanism) has to overcome a slight gap between the first lock part and the second lock part, which is necessary to form a door.

According to the invention, the pulling mechanism can provide a separate auxiliary trap to overcome this gap.

In any case, when the door is closed, the manual operation is coupled with the pulling mechanism. In this case in particular, manual activation of the actuation is only necessary anyway, since the manual actuation is typically activated in what is known as a panic situation.

For this purpose, a corresponding panic handle, a panic push bar or some other panic activation handle can typically be provided on the component (door leaf, wall or the like) on which the first lock part is provided. A the corresponding element can typically be actuated manually and is geared to the manual actuation of the first lock part. The manual actuation according to the invention therefore does not necessarily have to be implemented by one of the named manually grippable handles, but can be implemented, for example, by an attack provided in the first lock part, such as a nut or a similar component. In the event of a corresponding panic actuation on the first lock part, the lock latch of the second lock part should be released or moved into its release position. At the same time, a lock bolt that is typically present should also be transferred from its locking position into an unlocking position. Such a configuration simplifies the opening of the door in the event of danger, such as a fire or the like, since the lock latch and the lock bolt are adjustable, as it were. Such a panic function is standard in many doors today and is often required by law.

A corresponding panic handle is typically provided on the passive leaf side of a double-leaf door, and further typically on the inside of a double-leaf door, since a user in a dangerous situation has to step through the door to the outside in the event of danger.

According to the invention, the lock device can therefore typically be used in a multi-leaf, in particular double-leaf, door. The first lock part is typically installed in the passive leaf and the second lock part in the active leaf. Such doors can also be designated or designed as security doors, fire doors, escape doors or the like. In the case of double-leaf escape doors in particular, panic handles are used to release both the passive leaf and the active leaf of the escape door.

In principle, however, it is also conceivable that the system is used in a single-leaf door, with one of the lock parts, preferably the second lock part, being installed in the door leaf and the other lock part, preferably the first lock part, in the frame or in the one assigned to the frame Wall or a similar building element. Panic functions, in which the lock device according to the invention can be used in a particularly advantageous manner, may also be desired in such operations. In other words, the first lock part can be arranged in a door leaf, in particular the faceplate, or alternatively also in a door frame or a door frame.

An additional (conventional) panic function can also be assigned to the second lock part. A corresponding panic handle can also be assigned to this part of the lock (and in particular to the active leaf of the door). However, the invention explicitly relates to a panic function which originates from the first lock part and whose actuation is assigned, in particular, to the inactive leaf or not to the active leaf. The chain of action therefore typically extends over both lock parts and thus also both door leaves (while the panic function of the second lock part is typically only exhausted in the second lock part, i.e. usually in the active leaf).

At some distance from a corresponding door, for example, a button or the like can be located, which can interact with an electric door opener in the first lock part in order to open the door by remote control. A swivel shutter of the door opener, which otherwise blocks the lock latch, is then typically pivoted so that the door, in particular the active leaf, can be pivoted open without the lock latch having to be moved into the release position.

The active leaf of a corresponding door typically also has a conventional handle, such as a handle or the like, in order to open the door and to move the lock latch into the release position in a non-hazardous situation. A lock cylinder or a similar locking device can also be present, in particular also on the active leaf, in order to adjust a lock bolt between a locking position and an unlocking position. This allows the door to be "locked". This closing should be reversed as quickly as possible using the panic function described above.

The lock latch of the lock according to the invention can typically be a conventional lock latch, such as an oblique latch or the like. The front side of the lock latch can also be referred to as the head, the rest or other components of the lock latch as the body. In particular, the part of the lock latch can be referred to as the head which engages in the entry opening of the first lock part in the closed position.

Both the first and / or the second lock part each have their own lock housing. This typically has openings for the lock latch and / or the lock bolt or also an auxiliary latch. The openings are usually provided on both lock parts, since the elements mentioned are used precisely to keep the door in a closed state or to lock it.

The lock device according to the invention can in particular be a drive bolt lock, for example a panic drive bolt lock, in which in particular the inactive leaf provides at least one drive rod which is retracted by actuating a handle, in particular the panic handle.

At this point it should be pointed out again that "panic actuation" in the sense of the present invention means actuation in the first lock part, which is in particular associated with a corresponding panic handle. However, this should not rule out that the second lock part also has a (separate) panic actuation. This is typically independent of the panic activation in or on the first part of the lock. A panic handle can also be assigned to the second lock part, for example a panic bar on the active leaf.

According to the invention, the second lock part has a lock bolt. This lock bolt is provided in addition to the lock latch and is typically used to lock the lock and thus the door. Such a lock bolt can usually be opened with the aid of a lock cylinder and / or key or the like, while the lock latch can typically be displaced to open a door with a simple handle, such as a handle or a knob or the like.

In a locked state, the lock bolt typically engages in a bolt opening of the first lock part and can get out of this opening when it is moved into an unlocked position.

It can further advantageously be provided that the lock device comprises an operative chain from the manual actuation to the head of the lock latch, which (also) runs through the second lock part. In other words, when the door is closed, an effective chain is provided with the help of which a user can manually exert a tensile force on the head of the lock latch, for example via a handle (such as a panic bar or a panic latch) in order to move it out of the locked position into a release position to pull. The chain of action thus includes, in particular, manual actuation and the lock latch, but typically also several elements, in particular a transmission. For example, a lever and / or latch system can be provided in order to transmit the force from the actuation to the lock latch or its head. These elements can be arranged both in the first lock part and in the second lock part. The special feature is that the knitting chain not only runs through the first lock part, as in the prior art, but also along or through the second lock part. To this end, a gap provided between the two lock parts naturally has to be overcome, for which purpose a further, so-called auxiliary latch is typically provided, or, if necessary, the existing bolt could be used.

It should also be noted that said chain of effects is typically interrupted after the door is opened or before the door is closed.

The pulling mechanism can be part of the chain of action.

Advantageously, it is provided that the chain of action / the pulling mechanism first engages the body of the lock latch, whereby the head of the lock latch is also pulled. Of course, the invention also encompasses other realizable solutions.

A particularly advantageous embodiment of the invention is characterized in that the second lock part has a panic lever, which acts directly or indirectly on the lock latch, for pulling the head out of the entry opening. A corresponding panic lever can be, for example, a one-armed (or also multi-armed) lever, which is typically attached to the second lock part or the second lock part via a pivot axis. whose housing is attached. This panic lever can be the only lever of the pulling mechanism in the chain of action or it can also be part of a lever system.

The panic lever preferably acts directly on the lock latch, in particular on its body, in order to pull the head of the lock latch out of the entry opening. The panic lever is shifted by manually activating the manual actuation. This typically has an indirect effect on the panic lever. The actuation is therefore geared to the panic lever, at least when the door is closed. When the door is open, it can be correspondingly coupled to the actuation, namely by closing the door. The same also applies to the pulling mechanism mentioned in claim 1, of which the panic lever can in particular be a component. Typically, the panic lever is even one of the most important elements of the pulling mechanism.

It is further advantageously provided that the first lock part has an auxiliary slide. This auxiliary slide can typically cooperate with an auxiliary latch already mentioned above - prestressed into a closed position - and transfer it from the closed position into a release position. This auxiliary slide (and possibly also a lock bolt slide) are geared to the manual operation.

This auxiliary slide is therefore not unlike the plunger known from the prior art, but is arranged at a completely different point (not in the area of the electric door opener) and does not act directly on the lock latch or its head, but on an auxiliary latch.

In particular, the auxiliary slide is provided in addition to an existing lock bolt slide which can work together with said lock bolt. In a panic situation, when the manual actuation is activated, the lock bolt slide can ensure that the lock bolt is transferred from the locking position into an unlocking position.

For this purpose, an actuating slide can be provided in the first lock part in particular, which can be interposed between the manual actuation and the auxiliary slide (and in particular also the lock bolt slide). In particular, the operating slide can be used to operate both the auxiliary slide and the lock bolt slide.

At this point it should be noted that the auxiliary slide and the lock bolt slide are typically formed from separate elements. In principle, however, embodiments are also conceivable in which the auxiliary slide and the lock bolt slide are combined in one component and, for example, are formed in one piece. For example, a single component can provide different slide surfaces which, for example, can in particular also be arranged offset from one another (preferably with regard to the direction towards the second lock part).

The auxiliary slide is typically part of the chain of action, just like the auxiliary trap (depending on the definition or configuration, one or both elements can also be part of the pulling mechanism).

According to the invention, the second lock part has said auxiliary latch in addition to the lock latch (and possibly to a lock bolt). The auxiliary latch is particularly geared to the lock latch, and can thus act directly or indirectly on the lock latch in order to pull the head out of the entry opening. The auxiliary latch is advantageously also coupled to the panic lever and can act directly or indirectly on it, in particular to pivot it (which then leads to a displacement of the lock latch).

Thus, an effective chain can be provided in a particularly advantageous manner, which in particular comprises the following elements in the specified sequence: the manual actuation, the auxiliary slide, the auxiliary latch, the panic lever, the lock latch. However, this list is not to be understood as exhaustive. For example, an actuating slide provided for actuating the auxiliary slide (and lock bolt slide) can be part of the functional chain.

The auxiliary latch can be, for example, a typical linear latch, such as an inclined latch or the like, or a simple latch.

Furthermore, it can be provided according to the invention that the auxiliary latch engages in the bolt opening in a closed position. In this case it is typically arranged near the lock bolt, the lock bolt and auxiliary latch both being able to engage in the same opening in the faceplate of the first lock part. The lock latch is typically assigned a separate entry opening on the first lock part. The inlet opening and the bolt opening are therefore preferably formed separately. In an alternative embodiment, the bolt, auxiliary latch and lock latch can also be assigned to a common opening, a combined entry and bolt opening. In this case, the inlet opening would be a component or section of this opening. However, the openings are advantageously formed separately.

According to the invention it can advantageously be provided that the auxiliary latch is arranged in the area of the lock bolt and precisely not in the area of the lock latch. This enables an advantageous arrangement or configuration of the active chain or the pulling mechanism, since greater leverage forces can be achieved.

Finally, it is advantageously provided that the lock bolt, the lock bolt slide, the auxiliary slide and the auxiliary latch are arranged with respect to one another in such a way that activation of the manual actuation leads to a transfer of the lock bolt into an unlocking position before the head of the lock latch reaches the release position. Such an arrangement has the advantage that the pushing back of the lock bolt precedes that of the lock latch, so that the lock latch (as the component that actually keeps the door locked) is the last to be pushed back into the second lock part. This is achieved in particular if the lock bolt is moved into the unlocked position before the auxiliary latch reaches an open position. The second is not absolutely necessary, but ensures a subsequent transfer of the lock latch.

In other words, the lock bolt slide can in particular be displaced faster than the auxiliary slide. According to a particularly advantageous embodiment, this can be achieved in that both auxiliary slides and lock bolt slides are arranged differently or have control surfaces oriented. The control surfaces can be used to shift the slide in the direction of the second lock part. For this purpose, the control surfaces can have a different gradient, so that the slides can be displaced at different speeds, in particular by a common actuating slide. The control surfaces can be formed from the edge surfaces of an elongated hole, for example. In this case, the auxiliary slide and / or the lock bolt slide each have one Long hole, which in particular have a different slope. Of course, however, embodiments are also contemplated and encompassed by the invention in which the control surfaces are not parts of elongated holes, but, for example, edge surfaces of other elements, such as levers, plates or the like.

Furthermore, the object on which the invention is based is achieved by a method according to patent claim 10, which relates to the use of a lock device according to patent claims 1 to 9. At this point it should be noted that all of the advantages and subclaims or special designs explained in connection with the lock device described above can of course also be transferred to the independent patent claim 10 directed to a method.

Merely by way of example, it should be pointed out that a method should also be considered to be disclosed here, in which the lock bolt reaches an unlocking position before the head of the lock latch reaches the release position (or the auxiliary latch an open position) in which a lock bolt is displaced (in particular from a bolt opening, preferably as a result of the actuation of a panic handle), in which a chain of action from the actuation to the head of the lock latch is put into force (with the door closed), this chain of action also running along or through the second lock part, in which a panic lever acts on the lock latch, in particular by pivoting (namely to pull the head out of the entry opening), etc.

It should again be noted that this list is only to be understood as an example.

Further advantages of the invention emerge from the dependent claims, which may not be cited, and from the description of the figures which now follows. Show in it:

The following description of the figures and the claims should be preceded by the fact that the same or comparable parts may be provided with identical reference symbols, sometimes with the addition of small letters or apostrophes.

Fig. 1 shows the basic arrangement of a lock device 10 according to the invention in a door 11 in a schematic interior view. The door 11 shown is, for example, a double-leaf security door with a passive leaf 12 and an active leaf 13.

The lock device 10 is in Fig. 1 only indicated by dashed lines, since it would not actually be recognizable in the illustrated (schematic) frontal view. The dashed lines are intended to represent the basic positions of a first lock part 14, which in the exemplary embodiment can also be designated as a fixed leaf lock part 14, and a second lock part 15, which can also be designated as an active leaf lock part 15. A conventional door gap 16 can be seen between the two lock parts 14 and 15, or between the two door leaves 12 and 13, which in the present exemplary embodiment is shown much wider than it would in reality for reasons of clarity and schematic. In other words, the two door leaves 12 and 13 or the lock parts 14 and 15 actually lie (almost) against one another. Because of this, in Fig. 1 also the lock latch described later (as well as an auxiliary latch and a lock bolt), which extend out of the lock part 15 into the lock part 14, are not shown.

Both door leaves 12 and 13 show evidence Fig. 1 typically fittings 17a to d, which can fix the doors to an aisle wall (not shown) or the like. In the drawing, drive rod ends 18 and 19 associated with the inactive leaf are also indicated, which of course would not be visible in such a view, but would extend into corresponding ceiling or top wall or floor openings in order to additionally secure the inactive leaf 12 in its position .

The second lock part 15 in the active leaf 13 of the door 11 has according to FIG Fig. 1 a conventional opening handle 20 in the manner of a conventional latch, which can be used by a user by actuation to move the lock latch, not shown, from a closed position into a release position. At this point it should be noted that instead of the latch 20 shown, another handle could of course also be provided.

In addition, the second lock part 15 also has a lock cylinder 21 with which a user can actuate the lock bolt of the lock device 10, also not shown, and move it, in particular between a locking position and a release position. The lock cylinder 21 can be operated, for example, with a conventional key or the like and is used to unlock or lock the door 11 with the aid of the lock bolt.

The inactive leaf 12, in particular in the area of the first lock part 14, typically also has a handle 22, namely a so-called panic handle. This panic handle 22 can also be, for example, a latch 22a shown in dashed lines or the like. Alternatively, a panic handle 22b in the form of a panic bar can also be used, which is therefore also shown in dashed lines (Push rod) or, for example, a bar handle can be provided. This can, as shown, be arranged away from the lock part 14 or, alternatively, approximately in the area of the pawl labeled 22a, with which at least one side of the panic bar 22b would be in direct contact with the first lock part. Whatever the design of the panic handle 22, it ensures that an in is responded to in the event of manual panic actuation or activation Fig. 1 Actuation, not yet shown, in the first lock part 14.

Finally be regarding Fig. 1 also pointed to a hand-held button 23 which is only indicated very schematically and which can in particular have a connection to an electric door opener provided in the first lock part 14. This manual button 23 can, for example, be mounted on the aisle wall a few meters in front of the door and, when operated manually, can release the active leaf 13 so that the said user only has to push open the aisle door in order to pass through the door 11, in particular without to operate the handle 20.

It should be noted that the hand switch 23 typically cannot be used to open a locked door 11, since the hand switch 23 usually only provides for the release of the lock latch and not for unlocking the door (i.e. not for transferring the lock bolt in its release position).

In particular in the event of a panic, for example in the event of a fire or the like, a user would like to be able to open and unlock the door 11 completely with a single activation. For this purpose, one of the alternatively illustrated panic handles 22a or 22b is now being used, the actuation of which also leads to an unlocking of the door 11 (namely by transferring the lock bolt into its Release position) as well as for releasing the door 11 (namely by moving the lock latch into its release position).

The individual elements of the lock device 10 are in the Figures 2 to 7 shown in detail:
So shows Fig. 2 the lock device 10 with lock parts 14 and 15 arranged at a distance from one another. The gap 16 between the two leaves 12 and 13 of the door, or the two lock parts 14 and 15, is shown in FIG Fig. 2 Shown even more broadly in order to make the individual elements even more recognizable. It is of course to be assumed, however, that the lock parts 14 and 15, in particular their cuffs 24 and 25, are almost against one another when the door 11 is closed (and the gap 16 is minimized).

In the position according to Fig. 2 then (with a minimized gap 16) the lock latch 26 engages with its head 27 in the first lock part 14, in particular in the in Figure 7c with the reference number 28 provided inlet opening (what in Fig. 2 but is not shown due to the excessively wide gap 16 shown).

Fig. 2 shows the two lock parts 14 and 15 of the lock device 10 as they would be in a closed, but not locked door, in particular since the lock bolt 29 according to FIG Fig. 2 is in a withdrawn release position, in which he is not in the in Figure 7c with the reference numeral 30 engages the bolt opening. In said bolt opening 30 according to Figure 7c takes action accordingly Fig. 2 however, the so-called auxiliary trap 31, which is shown in Figure 7b is shown isometric.

Evidence Fig. 2 the auxiliary latch 31 is thus arranged in the area of the lock bolt 29, not in the area of the lock latch 26. Both the lock latch 26 and the auxiliary latch 31 are each in the Fig. 2 Position shown (spring) preloaded.

Said auxiliary latch 31 is in any case gear-coupled to a panic lever 32, which is one-armed in the exemplary embodiment and which can be pivoted about a pivot axis 33 fixed to the housing (from the auxiliary latch 31). In the context of such a pivoting, the panic lever 32 can strike a (cantilevered) contact surface 34 on the lock latch 26, in particular in the area of a body 35 of the lock latch 26. Said panic lever 32 thus serves to pull the head 27 of the lock latch 26 out of the entry opening 28 in the event of a panic.

In a conventional use case in which a user wants to open the door 11 in a conventional, manual manner, the user can, however, simply use the in Fig. 1 Actuate actuating handle 20 shown in the manner of a pawl, resulting in actuation of the in Fig. 2 The main follower 36 shown and the associated pivoting of the follower lever 37 for contacting a pressure surface 38 on the lock latch 26. This also leads to a transfer of the lock latch 26 into a release position, although this "standard case" is not further investigated or described in the present application because it is conventionally known.

A second possibility, also only described for the sake of completeness, of opening the door 11 by pivoting the door leaf 13, consists in actuating the in FIG Fig. 1 manual button 23 shown. This leads to actuation of the in Fig. 2 indicated electronic door opener 39, with the in Figure 7c The pivoting tray 40 shown is released by actuating the button 23 and according to FIG Fig. 2 extended lock latch 26 is no longer blocked in the area of its head 27 (which lies in the entry opening 28). Rather, the door leaf 13 can be pushed open in spite of the extended lock latch 26 (with the swivel drawer 40 according to FIG Figure 7c pivoted). Because the auxiliary trap 31 can be evidenced Figure 7b is provided with two inclined surfaces 43 and 44, the auxiliary latch 31 does not prevent the door 11 from being pushed open in this case. This case will also not be discussed in any further detail, although it should be noted that the electric door opener 39 is a conventional, unmodified door opener which can be used according to the invention, although a satisfactory panic function is provided via the first lock part 14.

Merely for the sake of completeness, it is also pointed out at this point that a certain panic function is also possible by actuating the second lock part 15. For this purpose, the second lock part 15 has a panic arm 41 which, for a panic function of the second lock part 15, can also lead to the lock bolt 29 being pushed open. However, this panic arm 41 has nothing to do with the pulling mechanism according to the invention, since it is not coupled to a panic actuation on the first lock part 14, which will be described in more detail later. For a detailed description of the panic arm 41 and the associated mechanism, refer to the DE 10 2008 015 655 A1 referred to the applicant. It should also be noted that a panic handle (here a panic bar) assigned to the second lock part 15 and assigned to the second lock part 15 (in particular connected to the panic arm 41) can also be provided on the active leaf 13 of the door 11.

Starting from Fig. 2 However, actuation of a panic function is not yet necessary anyway, since the position shown corresponds to a closed but unlocked door 11. In other words, the lock bolt 29 is still in a release position. To lock the door 11, a user can activate the lock cylinder 42, for example with the aid of a key (not shown), a lock bit (not shown) of the lock cylinder 42 for transferring the lock bolt 29 from the in Fig. 2 Approval position shown in the in Fig. 3 Locking position shown ensures.

In the position according to Fig. 3 thus also occurs the lock bolt 29 in the Figure 7c indicated bolt opening 30, with which the door 11 is locked.

Starting from the position according to Fig. 3 The panic function according to the invention will now be explained in more detail: The first lock part 14 has an actuation, in particular a panic actuation, in the form of a panic nut 45. This panic nut 45 is in accordance with the panic handle 22 Fig. 1 connected, so either with the panic latch 22a or the panic bar 22b. Regardless of how the panic handle 22 is designed, its manual activation leads to an actuation of the panic nut 45 and thus to its rotation with respect to it Fig. 3 especially counterclockwise. During this rotation, a first arm 46 of a two-armed nut lever 47 causes an actuating slide 48 to drop out of the position shown in FIG Fig. 3 shown in the in Fig. 4 shown, partially lowered position.

In the lower area of the slide 48 is evidently the Fig. 3 and 4th a first actuating pin 49, which is fixedly arranged on the slide 48 and engages in an obliquely arranged (kinking) elongated hole 50 of a bolt ejector or lock bolt slide 51.

Since the lock bolt slide 51 is additionally guided via a second elongated hole 52 and an auxiliary pin 53 (in particular fixed to the housing), the lowering movement of the actuating slide 48 leads via the first actuation pin 49 for an extension movement of the lock bolt slide 51 from the position according to FIG Fig. 3 in the position according to Fig. 4 (in the direction of entry or push-out direction E).

In addition, a second actuation pin 54 is fixedly arranged on the actuation slide 48, which in turn engages in an elongated hole 55 of an auxiliary latch ejector or auxiliary slide 56. Since said auxiliary slide 56, as in Fig. 3 shown, engages in the lock bolt slide 51, results in the lowering of the actuating slide 48 from the position according to Fig. 3 in the position according to Fig. 4 also to an extension movement of the auxiliary slide 56, initially in the in Fig. 4 position shown (in direction E).

A comparison of the Fig. 3 and 4th shows that the extension movement of the lock bolt slide 51 is faster than the extension movement of the auxiliary slide 56, which is due to the different design of the elongated holes 50 and 55, in particular because the elongated hole 55 of the auxiliary slide 56 has a greater slope than the elongated hole 50 of the Lock bolt slide 51.

In particular, the elongated holes 50 and / or 55 for this purpose each have control surfaces which are not provided with separate reference symbols in the figures and which can be contacted by the pins 53 and 54, respectively.

Like comparing the Fig. 3 and 4th also shows who leads in the figure transition from Fig. 3 to Fig. 4 The shown first section of the extension movement of the lock bolt slide 51 to a retraction movement of a nose 57 on the lock bolt 29. This nose 57 belongs to a release plate 58 that can be moved independently of the lock bolt 29, this upstream insertion movement of the release plate 58 leading to a lifting of a tumbler slide 59. This tumbler slide 59 locks the Lock bolt 29 namely, at least in the locking position. In the event of a panic, this locking must be released, which is why the release plate 58 is provided and can be actuated via the nose 57 (a very similar release plate is also in the one already mentioned DE 10 2008 015 655 A1 described by the applicant, there in particular in connection with the panic function of the second lock part 15, which is similarly integrated into the present lock).

In any case, in the partially extended position according to Fig. 4 the nose 57 (which at least passes through the head of the lock bolt 29) is retracted and the tumbler slide 59 thus releases the lock bolt 29. Therefore, if the operating slide 48 is lowered further from the position shown in FIG Fig. 4 in the in Fig. 5 The illustrated position of the lock bolt slide 51 and push the lock bolt 29, which is then no longer locked, completely out of the locking position, into the position shown in FIG Fig. 5 Approval position shown or the one in Fig. 6 complete release position shown.

Like the sequence of figures from Fig. 4 above Fig. 5 towards Fig. 6 shows, the lowering of the actuating slide 48 also leads to an extension movement of the auxiliary slide 56 and an associated retraction movement of the auxiliary latch 31 (both in direction E).

The figure transition from Fig. 5 to Fig. 6 shows that the movement of the slide 56 takes place more slowly than that of the slide 51.

The sequence of figures from Fig. 4 to Fig. 6 It also makes clear that this retraction movement of the auxiliary latch 31, due to its coupling with the panic lever 32, leads to a pivoting of the panic lever 32, with respect to the figures, in a clockwise direction, about its pivot axis 33. The panic lever 32 strikes the contact surface 34 of the during this movement Body 35 of the latch 26 and thus pushes the latch 26 out of the in Fig. 4 in the in Fig. 6 shown, complete release position (in direction E). In particular, the head 27 of the latch 26 is pulled into a release position, in particular out of the position shown in FIG Figure 7c inlet opening 28 shown.

In summary, by activating the actuation 45, the head 27 is pulled into a release position, in particular via an operative chain consisting of the actuation 45, the nut lever 47, the actuating slide 48, the auxiliary slide 56, the auxiliary latch 31, the panic lever 32, the contact surface 34, the body 35 and the head 27. The pulling mechanism according to the invention is provided in particular by the panic lever 32, further in particular by the contact surface 34, in particular by the auxiliary latch 31.

According to Fig. 6 a release position is now reached via the manual actuation 45 (by the panic handle 22) to the extent that both the lock latch 26 and the lock bolt 29 are in a release position (the same also applies to the auxiliary latch 31). In any case, the active leaf 13 of the door 11 can now easily be pushed open by the user activating the panic function. The same typically applies to the inactive leaf 12, although a special feature can be discussed here: When the, for example, in Fig. 3 shown, panic actuation 45 (via the handle 22) also the in Fig. 1 only indicated drive rod ends 18 and / or 19 are retracted. For example, lets Fig. 3 recognize a so-called rod slide 60 for the lower drive rod or the lower drive rod end 19, which can also be displaced via a second arm 61 of the nut lever 47 when the actuation 45 is activated, with reference to the sequence of figures from FIG Fig. 3 to Fig. 6 namely up. This enables the in Fig. 1 Drive rod end 19 shown are retracted.

A similar mechanism can also be provided for the upper drive rod end 18 (another drive rod, also not shown) (but this is not explicitly shown or recognizable in the figures). For example, in the embodiment shown in the figures, the upper drive rod can be arranged or fastened directly in the upper region of the actuating slide (the figures show an example of a groove not provided with a reference symbol in the uppermost region of the actuating slide 48). A special feature of the exemplary embodiment and the device according to the invention as a whole is therefore that an actuating element, for example the actuating slide 48, is provided, which is both part of the aforementioned chain of action and can also provide the adjustment of at least one (preferably of two) drive rod (s) . In other words, such an element can actuate one or more drive rods as well as the auxiliary slide 56 and / or the lock bolt slide 51. Embodiments are also affected in which only a lower or upper drive rod locking is provided.

Finally, refer to the isometric views according to Fig. 7 referenced, some of which have already been discussed above. So shows Figure 7a an isometric view of the second lock part 15, Figure 7b an isometric, already discussed view of auxiliary trap 31, Figure 7c an isometric view of the first lock part 14, which has also been discussed, Figure 7d an isometric view of the auxiliary slide 56 and finally Figure 7e an isometric view of the lock bolt slide 51, the last two representations in particular making it clear that the two slides 51 and 56 can interlock in order to enable a certain mutual guidance (in particular for the auxiliary slide 56).
