Technical Field

The invention relates to a self-locking lock, in particular an emergency lock, comprising: a lock housing; a locking pin which can be moved in and out of the lock housing and is mounted in such a way that it can be actuated by means of a control slide; a releasable first locking device for locking the locking bar in its moved-in position; a control bolt configured to release the first locking device when moved into the lock housing; a second releasable locking device which locks the control bolt in its extended position; and at least one further bolt, which is mounted in the lock housing so as to be movable in and out, is designed to release the second locking device when it is moved into the lock housing, the control bolt and the further bolt being arranged relative to one another in such a way that the further bolt, when the lock strikes the associated locking plate (Schlie β blech), is moved into the lock housing at least so far before the control bolt that the further bolt releases the second locking device in such a way that the control bolt can also be moved into the lock housing.

Background

Such locks are used, for example, in escape doors. A self-locking lock is basically provided for automatically placing the bolt of the lock in the extended position, i.e. the locked position, when the door equipped with the lock is closed. The first locking device serves in particular to lock the locking bar in its retracted position when the door is open. This ensures that: the latch does not prevent the door from closing.

When the door is closed, the first locking means should be released so that the bolt can be automatically removed and the door can be locked. This is done via a control latch. Such a control bolt is typically provided such that it is pressed in by the catch plate when the door is closed and the first locking means is released, i.e. releases the bolt, for removal.

Problematic in this connection are: the control bolt is pressed in despite the door being opened and the lock being remote from the stop plate. This can be done, for example, by inadvertent contact with the control bolt. Furthermore, the control bolt can be pressed in abusively for the purpose of removing the bolt and thus preventing the closing and blocking of the door.

To overcome this problem it is known: the control latch is latched in the open position of the door. For this purpose, a second locking device is provided here. The second locking device is released by the additional bolt, if the door is closed, i.e. when the lock strikes the locking plate, in such a way that it is immediately in front of the control bolt, so that the second locking device is released again in such a way that the control bolt can also be moved into the lock. Thus ensuring that: the door cannot be held in the open position simply by pressing in the control bolt.

Known solutions for locking a control bolt are often structurally complex and often have additional components that are not necessary for the actual function of a self-locking lock.

Disclosure of Invention

The object of the present invention is to provide a self-locking lock of the type mentioned at the outset which is of particularly simple construction.

The object is achieved by a self-locking lock according to claim 1, and in particular by the second locking means being formed by the control slide.

Instead of a possible additional component, a component for releasing the first locking device is therefore used, which is originally provided in the lock, i.e. which operates the bolt. This allows a particularly simple construction of the lock without additional components. In particular, when the control bolt is locked in its extended position, the control slide and the control bolt are directly in engagement with one another, for example via corresponding locking projections.

The control slide is preferably coupled to the latch in such a way that when the control slide is in the first position, the latch is in the extended position and when the control slide is in the second position, the latch is in the extended position thereof. By means of the coupling, the position of the control slide is associated with the position of the locking bolt. Since the control slide forms the second locking device, the state of this second locking device is therefore coupled directly to the position of the locking bar in a simple manner. Thus, it is ensured in a simple manner and without additional components that: the control latch is only latched when the bolt is moved in, i.e. when the door (when operating as intended) is open.

The first position and/or the second position are in particular the rest positions of the control slide. That is, when no manipulation of the lock is performed (whether by a button, key, motor or by pressing in the deadbolt), the control slide valve remains in the relevant position.

Preferably, in a predetermined operation, the first position of the control slide is associated with a closed state of the door equipped with the lock, and the second position is associated with an at least partially open state of the door. The at least partially open state is understood to mean a state in which both the control bolt and the further bolt are at least at a minimum distance from the locking plate and are therefore in particular not actuated and removed.

According to a particularly simple embodiment, provision is made for: the first locking device is provided to lock the locking bar in the retracted position of the locking bar in that the control slide valve is locked in the second position of the control slide valve. In this case, the coupling of the control slide to the locking bar is advantageously used for actuating the locking bar in order to lock the locking bar by means of an already existing component, namely the control slide.

In one embodiment, the first locking device is formed by the control bolt. This also simplifies the construction. The control bolt itself thus acts to lock the locking bolt in the retracted position, and additional components can be dispensed with. In particular, the first locking device is active when the control bolt is in the extended position of the control bolt. Preferably, a first locking device or a control bolt can be provided for locking the bolt indirectly via the control slide in the retracted position of the bolt. In this case, the control bolt and the control slide valve are advantageously used to lock the control slide valve, in particular in the second position of the control slide valve, directly in engagement with each other. No additional components are required. The control bolt is preferably provided to prevent the bolt from reaching the extended position in the extended position, in that the control bolt engages with the control slide valve and thus locks the control slide valve in the second position.

According to a further embodiment of the invention, provision is made for: the second locking means is active when the control slide is in the second position when the control bolt is moved out. Thus, it is ensured in a simple manner that: when the lock bolt moves in, the lock controls the lock bolt. However, the second locking means is not active, in particular when the control slide is in the third position. In other words, the control bolt is releasable for movement into its moved-in position by the control slide moving from its second position into its third position. In the third position of the control slide, the control bolt can thus be pressed in, so that the removal of the bolt, i.e. when the lock is moved into the associated locking plate, can be achieved. The control slide valve as a central element of the lock must therefore simply be moved into its third position in order to release the control bolt for movement in. The movement path can in particular be implemented relatively short. Preferably, the second position is between the first position and the third position of the control slide.

In a further advantageous embodiment, in the second position of the control slide valve, both the first locking means and the second locking means are active for locking when the control bolt is removed. In this case, the control bolt and the control slide valve are preferably in direct engagement with each other for locking the control slide valve and/or for locking the control bolt.

The first locking means may comprise, for example, a first locking projection on the control slide and/or the control bolt. The latch can thereby be locked with simple means. Advantageously, the first latching projection on the control flap can be used for engaging with the control flap, in particular with the first latching projection of the control flap, and/or the first latching projection on the control flap can be used for engaging with the control flap, in particular with the first latching projection of the control flap.

Another embodiment of the invention provides that: the second latching means comprises a second latching projection on the control slide and/or the control bolt. Thus, the control bolt can be locked by simple devices. Advantageously, the second latching projection on the control bolt can be used for engaging with the control bolt, in particular with the second latching projection of the control bolt, and/or the second latching projection on the control bolt can be used for engaging with the control slide, in particular with the second latching projection of the control slide.

The latching projection can be formed in a simple manner on the component concerned, for example within the scope of the originally provided method steps.

According to a particularly advantageous embodiment, the second locking projection is formed on the first locking projection. Conversely, the first locking projection can also be formed on the second locking projection. Both enable a particularly simple construction.

According to an alternative, which is also structurally simple, the first locking projection and the second locking projection on the control bolt or on the control slide can be formed by the same projection. In this case, the first and second locking means can preferably be acted upon by different contact surfaces of the projection.

In a particularly preferred embodiment, a second latching projection on the first latching projection is formed on the control slide and, on the control bolt, the first latching projection and the second latching projection are formed by the same projection.

In a further development of the invention, it is provided that the control slide has at least one third position, in which the latching bar is in the latching bar insertion position when the control slide is in the third position, and/or in which the second blocking means is deactivated when the latching bar control slide is in the third position. This makes it possible in a simple manner to release the second locking means, in particular without removing the locking bolt. The third position may preferably be a transitional position, i.e. in particular not a rest position. The control slide can be brought into the third position, for example, only for a short time interval in order to release the second locking device.

According to one embodiment of the invention, the second and third positions of the control slide can be associated at least substantially with exactly one position of the locking bar, i.e. exactly one moved-in position. In particular, the movement of the control slide from the second position into the third position does not result in a movement of the locking bar. This can be ensured by a correspondingly shaped chute guide, for example, in a vertical guide portion. Alternatively, in particular only a small movement of the latch can however also be accompanied by a movement of the control slide from the second position into the third position and/or vice versa. The decisive points are: the locking bolt is moved so far into both the second position and the third position of the control slide valve that the associated locking plate of the control slide valve does not act on the locking of the associated door leaf or prevent the movement of the lock into the locking plate. The moved-in position of the latch is generally characterized in that the latch does not act on the latch. The locking pin can therefore be moved freely within the lock housing within the scope of its moved-in position, provided that it does not protrude from the lock plate (Schlossstulp) of the lock housing or does not protrude from it in a locked manner.

In a further embodiment of the invention, a third releasable locking device is provided for locking the further bolt in the extended position of the further bolt. The additional bolt thus forms an additional blocking element when the third locking device is activated. According to a particularly simple embodiment, the third locking device can again be formed by the pilot slide valve.

The third locking device is effective in particular when the control slide is in its first position, i.e. when the door is completely closed and the latch is removed during normal operation.

In addition, the third locking device is inactive, in particular, when the control bolt is locked in the extended position of the control bolt and the control slide valve is in the second and/or third position of the control slide valve, i.e. when the door is at least partially open and the bolt is moved in when operating as intended.

In a further embodiment of the invention, the further locking tongue is coupled to the control slide valve in such a way that an inward displacement of the further locking tongue brings the control slide valve from the second position, in which the control locking tongue is locked, into the third position, in which the control locking tongue is released. This results in a particularly simple possibility for releasing the control bolt by means of the further bolt. In this case, the further locking tongue moves the control slide valve, preferably in a direction pointing away from the first position of the control slide valve. The control slide is preferably prestressed in a defined position, in particular in the first position, for example by means of a spring. The further locking bolt, when moved in, moves the control slide valve, in particular counter to the pretensioning.

The further locking tongue can preferably be designed as a cross locking tongue. Such a cross bolt forms a reliable means for additional locking in the closed state of the door and for actuating the second locking device in order to release the second locking device when the door is closed. The cross bolt also advantageously prevents the locking of the bolt under preload. This proves to be advantageous in particular with regard to emergency safety, since the door can then also be unlocked and opened when someone has pressed against the door leaf. In principle, a plurality of further latches, preferably two separately arranged further latches, which together are also referred to as double cross bolts, can also be provided. In this case, the locking bar is preferably arranged between the further locking bars and is in particular designed separately from the further locking bars.

In principle, the at least one further bolt and the control bolt are provided for actuating the further bolt first and then the control bolt when the lock strikes the locking plate. For this purpose, the additional locking tongue can be arranged in particular in the closing direction before the control locking tongue.

The control bolt is preferably mounted so as to be movable, in particular movable, between a moved-out position and a moved-in position. The control bolt is further preferably pretensioned into its removal position. The pretensioning can be achieved, for example, by a spring.

The control slide can be movably, in particular vertically and/or parallel to the plate (Stulp), and/or coupled to the locking bar by a slotted guide.

The control slide and/or the latch can be pretensioned into a position in which the latch is moved in particular and/or into a first position of the control slide. In particular, the control slide can be pretensioned into its first position, and the latching bar is likewise pretensioned indirectly via the control slide, i.e. into the extended position of the control slide.

Furthermore, the further locking tongue is preferably likewise prestressed, in particular prestressed, into the extended position of the further locking tongue.

In principle, the blocking of the lock is controlled via the movement of the control slide. The control slide may be movable, for example, via a button, a key and/or a motor. The lock comprises in particular a split or half button slot (druckeruss) so that unlocking from the outside cannot be achieved with a button. In particular, it may be possible to use a key for unlocking the lock from the outside. Preferably, a continuous lock cylinder can be provided for unlocking the lock both from the outside and from the inside by means of a key.

The self-locking function of the lock is in particular designed to be mechanically self-locking, i.e. the locking takes place by a mechanical process, in particular with the aid of at least one spring. The self-locking is not driven by the motor and is therefore driven independently of the supply of current. Self-locking is used for automatic locking removal at each closing of the door.

The lock may be, for example, an emergency lock. Such an emergency lock is characterized in that the door can be opened from one side, typically from the inside, by means of a push button, also when the door is closed. Here, the push button causes the displacement of the latch and thus the unlocking. The emergency lock is, for example, installed in an escape door and therefore always permits escape in a predetermined escape direction in a particularly simple manner.

Detailed Description

In fig. 1 to 6, a lock 10 is shown with a lock housing 12, the lock housing 12 being arranged on a lock plate 14. Fig. 1 shows lock 10 in an installed orientation. The vertical direction in fig. 1 then corresponds to the vertical direction in the operation of the door equipped with the lock 10. Furthermore, the lock 12 comprises a bolt 16, two cross bolts 18, a control bolt 20 which projects from the lock plate 14 in the operating state according to fig. 1, and a control slide 22.

The operating state shown in fig. 1 corresponds to a completely closed door in the intended operation. The latch 16 is removed, i.e. the door is latched. The cross-bolt 18 is likewise removed and additionally latched in action. Control bolt 20 is in the moved-in position and control spool 22 is in the first position.

The control slide 22 is coupled to the latch 16 in such a way that, when the control slide 22 is in the first position shown here, the latch 16 is in its extended position, as shown in fig. 1. Furthermore, the coupling between the control slide 22 and the latch 16 is designed in such a way that when the control slide 22 is in the second position, the latch 16 is in its moved-in position, as is shown in fig. 4. Furthermore, the control slide 22 comprises a possible third position, which is shown in fig. 2, 3 and 5 and in which the latch 16 is likewise moved in.

The coupling between the control slide 22 and the locking bolt 16 is realized by a slotted guide, i.e. by a guide pin 24 on the control slide 22, which is guided in a guide recess 26 of the locking bolt 16.

The lock 10 can be placed in the unlocked state by actuating a button and/or by actuating the lock 10 with the aid of a key. For this purpose, lock 10 comprises a button notch 28 for coupling with a button not shown here and a lock cylinder 30 for coupling with a key not shown here. Actuation by means of a button or key causes: when the control slide 22 is moved from the first position shown in fig. 1 into the second position shown in fig. 4, the control slide 22 is moved upwards. Due to the coupling with the control slide 22, the locking bar 16 is moved into its moved-in position, i.e. the unlocked position, via the slotted guide 24, 26. The lock 10 also comprises, in particular, a motor for motorized unlocking, which is not shown in detail here, and which is likewise provided for bringing the control slide 22 into its second position in order to unlock it.

Furthermore, the control slide 22 is prestressed into its first position shown in fig. 1, so that the locking bar 16 is in principle inclined into its extended position and is therefore automatically extended for locking when the control slide 22 is unlocked, as will be explained below. In this case, the bolt 16 can also be actuated, in particular via a push button, in order to be moved in, so that the door can also be opened keyless in the event of escape.

The control bolt 20 and the control slide 22 form a first and a second locking device in the above sense. In this case, the control bolt 20 and the control slide valve 22 are directly in engagement with one another for locking, i.e., in the second position of the control slide valve 22, as is shown in fig. 4.

The second position of the control slide 22 and the progression in the lock 10 in general when opening and closing the door are explained in more detail by means of the states illustrated in chronological sequence by means of fig. 1 to 6. The first and second locking means are first explained in detail with regard to their structural design. Reference is first made to fig. 7 for this purpose, which shows the control bolt 20 in a legal view corresponding to the view from below in fig. 1. The tip 32 of the control bolt 20, which is oriented to the left in fig. 7, protrudes more or less outward from the locking plate 12 in the operating state. Fig. 4 shows the control bolt 20 in its moved-out position, whereas fig. 1 to 3, 5 and 6 show the control bolt 20 in its moved-in position. The control bolt 20 protrudes a little outward from the lock plate 12 in its moved-in position.

Fig. 7 shows a particularly good view of the projection 34 of the control bolt 20, which is intended to engage with the control slide 22. Furthermore, the control bolt 20 comprises a recess 36 for engaging a spring, not shown in detail, which causes a pretensioning of the control bolt 20 into its extended position. Finally, the control bolt 20 comprises a magnet 38, which displays the position of the control bolt 20 for an engine control device, which is not shown in detail.

Fig. 1b, which forms an enlarged view of the region Z indicated in fig. 1a, shows a further region a, which is shown in fig. 8 in a strongly enlarged manner. There it can be seen particularly well that: the control slide 22 comprises a first locking projection 40 and a second locking projection 42 formed on the first locking projection 40. When the control slide valve 22 is in its second position when the control bolt 20 is removed, the projection 34 of the control bolt 20 is arranged in the recess 44 indicated in fig. 8, so that the control bolt 20 is in direct engagement with its projection 34 with the control slide valve 22, i.e. with the first locking projection 40 and the second locking projection 42. This operating state is shown in fig. 4.

The construction of a cross bolt 18 known per se in terms of its operating principle is also briefly discussed with the aid of fig. 1 b. The two cross bolts 18 are similar and are ultimately redundantly constructed. The respective cross bolt 18 comprises two movable bolt elements 46. These bolt elements can be locked in the extended position by the control slide 22 via the roller element 48 connected to the control bolt 20. The control slide 22 thus forms a third locking device in the above sense, which is active in the operating state shown in fig. 1. The roller element 48 is supported on a locking device 50 of the control slide 22. When the cross bolt 18 is locked in its moved-out position, the bolt elements 46 are locked relative to one another and act in addition to the bolt 16 as blocking elements. When the third locking device is not active, as is the case in fig. 2 to 5 and described in more detail with the aid of these figures, the bolt elements 46 are not locked to one another, but can be moved relative to one another and then form a start ramp in order to push the cross bolt 18 into the housing 12 via the stop plate.

After some selected functional features of the lock 10 have been described above in advance, the complete operating cycle is described below with reference to fig. 1 to 6, which takes place from the fully closed door in fig. 1 without actuation via the open door in fig. 4 without actuation and back to the fully closed door in fig. 6 without actuation. Fig. 2, 3 and 5 show intermediate states during the actuation.

In fig. 1, the lock 10 is shown in an operating state, which corresponds to a rest state when the door is closed. The latch 16 is in its removed position and extends into a corresponding void in the stop plate. The control slide 22 is in its first position, which is associated with the extended position of the bolt 16. The control bolt 20 is in its retracted position, since it is pressed in by a stop plate, not shown here, in the closed state of the door. The cross bolt 18 is in its removed position and extends into a corresponding recess in the stop plate. The cross bolt 18 locks, i.e. constitutes an additional lock. The cross bolt 18 is locked by the third locking device, i.e. held in the extended position by the roller element 48 and the locking device 50.

Starting from the closed position, the door should be opened. For this purpose, the push button is actuated by way of example, so that the lock 10 assumes the state shown in fig. 2. The button notches 28 are here provided in corresponding positions. However, the lock 10 can also be operated, for example, by a key via the key cylinder 30 or by a motor in order to open.

Manipulation of the button and corresponding rotation of the button notch 28 causes: starting from the first position shown in fig. 1, the control slide 22 is moved upward, i.e. into the third position shown in fig. 2, by means of a coupling not shown in detail here. The third position of the control slide 22 is associated with the retracted position of the locking bar 16 via the slotted guide 24, 26, as in the second position. The door can then be unlocked via the button.

In the operating state shown in fig. 2, the door is also completely closed. Correspondingly, the cross bolt 18 is removed. However, in contrast to fig. 1, this cross bolt is not locked via the third locking devices 48, 50. In particular, the cross bolt 18 is released for movement in and the bolt elements 46 referenced in fig. 1 are not locked to each other, but are "soft". Because the latch 16 is also moved in, the door can be opened.

In this case, the cross bolt 18, which is moved out of the recess of the locking plate in the closed state of the door, runs past the edge of the locking plate and is moved into the lock housing 12. This state is shown in fig. 3. The control slide 22 has a recess 52 into which the cross bolt 18 can be moved with the roller element 48 when the control slide 22 is in the third position, as in fig. 2 and 3.

Once the lock 10 has been at least partially opened away from the associated stop plate, i.e. the door, the pretensioned control bolt 20 is removed. In this case, the control bolt 20 is then prevented from moving further out than the moved-out position of the lock housing 12, in that the projection 34 pushes and locks against a further locking device 54 of the control slide 22, which is indicated in fig. 3 b. Furthermore, the cross bolt 18 is also moved out, which is likewise pretensioned into its respective moved-out position.

When the pushbutton is now released when the door is at least partially open, the control slide 22 follows its pretension downwards, but is locked in the second position by the control bolt 20, i.e. by engagement with the projection 34 of the first locking projection 40. This state is shown in fig. 4.

In fig. 4, the first locking device for locking the locking bar 22 in its moved-in position then acts via locking the control slide 22 in the second position. The first locking means includes a first locking protrusion 40 that controls the spool 22 and a protrusion 34 that is a first locking protrusion that controls the locking tongue 20.

In fig. 4, a second locking device for locking the control bolt 20 in its extended position is also active. The second locking means includes a second locking protrusion 42 that controls the spool valve 22 and a protrusion 24 that is a second locking protrusion that controls the dead bolt 20.

In terms of the control slide 22, the second locking projection 42 is formed on the first locking projection 40. In terms of controlling the locking bolt 20, the first and second locking projections are formed by the same projection 34, and the first and second locking means are acted upon by different contact surfaces of the projection 34. These are the upper contact surface, on which the first locking projection 40 acts, and the right contact surface, on which the second locking projection 42 acts, in fig. 4 b.

The door typically includes a door closer so that the door is pre-tensioned into its closed position. By moving the latch 16 at least when operating as intended into the at least partially open position of the door, the door can always be closed reliably and then automatically closed.

The locking tongues 18, 20 are therefore activated on the catch plate when the door is closed, for example, manually or via a door closer, starting from an at least partially open position. The locking tongues 18, 20 are arranged such that first the cross locking tongue 18 is activated and actuated for the insertion. Starting from the position shown in fig. 4, the respective cross bolt 18 is thereby actuated with its roller element 48 on an actuating ramp 56 of the control slide 22. This results in: starting from the second position shown in fig. 4, the control slide 22 is moved upward, i.e. into the third position shown in fig. 5.

When the control slide valve 22 is in its third position, as shown in fig. 5, the projection 34 of the control bolt 20 is no longer in engagement with the second latching projection 42 of the control slide valve 22. Thus, control bolt 22 may be brought into its moved-in position by the stop plate. As already indicated, for this purpose, the control bolt 20 is first activated on the locking plate and is moved in when the cross bolt 18 is actuated. To achieve this, the control bolt 20 is arranged a short distance behind the cross bolt 18 in the closing direction.

In fig. 5, control bolt 20 has been moved in. However, the stop plate is still active and the cross bolt 18 has not yet been removed again. The door has not yet fully closed.

When the door is then completely closed, the lock 10 assumes the state shown in fig. 6, which finally corresponds to the state of fig. 1. The cross bolt 18 moves out of the corresponding recess of the locking plate due to its pretensioning. The control bolt 20 remains pressed in by the stop plate. The control slide 22 causes its pretensioning into the first position, which is possible because the projection 34 is not arranged in the vertical path of movement of the first locking projection 40, i.e., because the first locking device is inoperative. The latch 16 is moved out via the chute guides 24, 26. In addition, the third locking device is again activated. The cross bolt 18 is locked via the respective roller element 48 and the locking device 50 of the control slide 22.

For the irregular case of the removal of the locking bolt 20 when the bolt 16 is removed and the control slide 22 is in the first position, the control slide 22 comprises an actuating ramp 58, which is formed on the first locking projection 40 and is indicated in fig. 6 and 8. When the pilot slide valve 22 moves upward, the projection 34 of the pilot bolt 20 starts on this start ramp. In this case, the control bolt 20 is moved in by the engagement of the projection 34 with the start ramp 58, so that the control slide 22 is not locked and the projection 34 is brought into a position from which it can be brought into engagement with the locking projections 40 and 42.

The self-locking lock 10 described above makes it possible in a simple manner to prevent unintentional removal of the bolt 16 by unintentional actuation of the control tongue 20 when the door is opened. Without the second locking device, the bolt 16 would move out when the control tongue 20 is actuated, so that it is no longer possible to close the door.

The second locking device, via a second locking projection 42, which is designed here as a hook, is used when the lock 10 is unlocked and the cross bolt 18 is unloaded: control tongue 20 may not be manipulated. If the door now falls into the jamb, i.e. the lock 10 is activated on the catch plate provided on the jamb, the cross bolt 18 is first actuated slightly before the jamb or catch plate is brought into contact with the control bolt 20. If the cross bolt 18 is actuated, the control slide 22 is lifted slightly, so that the movement of the control bolt 20 is no longer blocked by the second blocking projection 42. Lock 10 may then only be locked when cross bolt 18 is first operated and control bolt 20 is then operated. Thus, inadvertent latching of lock 10 via control bolt 20 when the door is open is effectively prevented. Unintentional incorrect operation is virtually eliminated by the second locking device which forms the mechanical anti-slip device.

The current solution for realizing a mechanical anti-spin device can be accomplished without additional components. The known solutions require, in part, a plurality of additional mechanical components.
