Abstract

A lock has a spring-loaded double-arm latch (4), an element (8) movable in the longitudinal direction of a lock housing (1) and operating together with a bolt (3), and a spring-loaded control element (5) which fixes the element (8), with the bolt (3) drawn into the housing (1), into an arrested position. To actuate the element (8) two independent locking cylinders (18,19) are provided or the actuation of the element (8) can be electrically controlled.

Description

The invention relates to a self-locking, electromechanical panic lock according to the features of claim 1.

The CH 473 298 describes a right and left usable door lock. This door lock has a lock housing in which slidably in the middle of a latch and a symmetrical with respect to the symmetry line of the trap actuating mechanism for the case. In this case, a symmetrically formed actuating slide is present, which can act by inserting the lock latch into the lock housing respectively by having at the ends of the actuating hook by nuts on the two-fold via a nose. Furthermore, depending on the type of installation, one of the two lock cylinders can be used, by means of which locking lug an actuation of the lock catch is possible. As already stated, the present door lock for right and left-hand doors is usable and thus constructed around a central line extending through the lock latch, a mirror image. Thus, on each side of the center line are each a nut and one of the lock cylinder.

Normally, door locks are prepared for the use of only one lock cylinder. This gives the key holder for the corresponding lock cylinder the access authorization to the respective door. Such lock cylinders can be part of a locking system. However, a locking system is a combination of related locking cylinders and of course their keys. Such a staggered arrangement of the lock cylinder makes it possible to assign different groups of persons a hierarchically ordered access authorization.

For certain doors, however, it is desirable to allow a keeper-independent access authorization. Such doors are to be found, for example, in the area of transformer stations or the like, where in addition to the known access authorized also each example, the fire department must have access.

As the aforementioned prior art shows, door locks which are prepared for receiving a plurality of keys are aligned as manually operated door locks. However, these door locks are very complicated in construction, since closed only over both keys of the bolt back and forth and the change over the case can be operated independently.

So is out of the DE 299 05 712 O1 a castle with a main and secondary closure has become known. In such a lock, closing the bypass cylinder prevents opening or closing of the main cylinder.

A lock with a second locking device is the DE 199 06 271 C2 to be found in which in addition to the use of a lock cylinder and a waistband key can be used to close.

The DE 196 30 972 A1 discloses a lock that includes an emergency backup and thus allows easy opening from the inside of the room. However, the door is protected against unauthorized opening from the outside. The lock offers the possibility to use two lock cylinders. In addition to a primary trigger latch, there is also a secondary trigger latch.

In the EP 0 882 859 B1 discloses a lock fitting system consisting of a mortise lock having a latch, a latch, a first profile cylinder and a second profile cylinder disposed on the side of the first profile cylinder opposite the forend.

A lock for high security doors will be in the DE 198 26 869 C1 described, wherein the Sperrzuhaltung and the Schließzuhaltung are connected by a releasable for a conversion of the Schließzuhaltung coupling with each other, also provided with a secured by the tumbler set change for the operation of a case by a double-bit key with different beards. In order to form the tumblers in such a lock for the purpose of waiving tumbler with closed closing channels and to make a case operation without repositioning the Doppelbartschlüssels, the convertible Schließzuhaltung is in two parts from an upper part of the closing channel containing upper part and a lower part of the closing channel containing lower part ,

The DE 101 22 466 A1 refers to a lock with a retractable by a locking lug of a profile cylinder against the force of a spring from the closed position and two counter-moving Basquillstangen that can be transferred only in retracted trap by means of a handle from its closed position to a retracted position, both the case as also the Basquillstangen by means of an emergency release from its closed position or excluded position are movable out. Such a lock has two side by side located profile cylinder.

As the prior art shown here shows, such door locks are prepared for receiving a plurality of keys and thus closing types are very complicated as manually operated door locks in their construction.

An electromechanical drive and an electrically driven lock and an access control method with this device, the DE 694 05 749 T2 be removed. In this document, in addition to an electric drive and end position sensors are described, which serve to deliver corresponding electrical signals when a control has reached its working position and its rest position.

The object of the invention is to provide a simple self-locking, electromechanical panic lock, which is simple and inexpensive to manufacture and easy to use in the operation. In this case, such a self-locking panic lock should also be able to be operated by several independent, authorized persons and at the same time such a panic lock should offer the possibility that its functions can be monitored. Furthermore, such a panic lock in addition to the mechanical operation should also be able to be operated automatically.

The object is solved by the features of claim 1. The dependent claims provide a further embodiment of the inventive concept again.

There is provided a self-locking panic lock for a door, with a spring-loaded double-legged latch and a slidable in the longitudinal direction of the lock housing member which cooperates with a latch, and a spring-loaded control, which fixes the member in retracted into the lock housing latch in a locked position. Furthermore, the lock according to the invention has a nut which has a driver connected to the member and thus also allows manual actuation of the lock on the nut. In addition, the operation of the lock with two independent locking cylinders is possible.

Such self-locking panic locks must automatically extend the latch when closing or closing a door. Thus, such a door is always closed at any time. However, to open such a door again, there are various possibilities. One of the possibilities of a door, which is aligned with such a self-locking, electromechanical door lock according to the invention, can be unlocked, for example, from a control room or the like remotely by an electrical signal. In order to be able to effect an opening of the door, the translatory element which brings about the locking mechanism into the lock housing must be actuated correspondingly via a motor drive or the like. In this case, for example, is driven by an electric motor in conjunction with a gear part of the nut or the whole nut. Since this is in operative connection with the translatory member, thus an automatic displacement due to the motor forces of the translational member can be effected.

In addition to the design as an electric motor, but also an electromagnet can be used. Such an electromagnet would cause the rotation of the nut and thus the displacement of the translatory member due to a ram driven by it. Such an electromagnet is smaller than a motor drive and therefore can preferably be used in the field of tubular frame locks.

Since such self-locking panic locks are used in doors in escape and rescue, it can come in a panic case to a strong pressure on the door leaf. The operation of the panic lock must not turn out to be counterproductive, which means that the bolt must always be retracted, even if over the Door pressure is exerted on the lock. For this reason, a double-sided trap is present, which is wider in width than the bar. Furthermore, the case is rigid with locked bolt and can not be pressed into the lock housing. Thus, a secure centering within the striking plate on the case is possible, at the same time dips the bolt with corresponding lateral play within the strike plate.

Such a self-locking panic lock with a translationally displaceable member is easy to set up and includes a quasi-safety device, which ensures that only when retracted latch in the lock housing, the case is unlocked. In addition, a control is present on the lock, which also cooperates with the translational member. By the entry of the bolt, the control is virtually biased and at the moment where the door closes, the protruding from the forend control comes into contact with the strike plate and releases the time delay after dipping the two-part latch in the strike plate the bolt. Thus, it is always ensured that the bolt can only enter into the strike plate when the two-piece double-legged trap has penetrated into the strike plate. After the latch is latched into the strike plate, the movable double-legged latch becomes rigid, so that no pressure can be produced on the door leaf due to its greater geometric width relative to the latch on the latch. The stunned trap is virtually a bar.

Due to the design of the displaceable member, it is possible to constructively arrange a second lock cylinder in the same lock housing in a simple manner. This can be done both side by side and on top of each other. A significant simplification results over the known conventional solutions of the prior art in that the closing lug of the second lock cylinder the same term acts directly or indirectly. In this case, the translationally displaceable member as a central component controls both the bolt stroke and the case movement. The closing of the bolt is carried out automatically as already described, so that only the latch assembly must be made via one of the two cylinders. In this case, the double-legged trap is unlocked in an upper end position of the slide. With the opening movement of the door, this unlocked case is spring-loaded pushed back into the lock housing and does not need to be withdrawn as in the known locks via a separate lever assembly through the lock cylinder. Thus, by a simple extension or broadening of the translational member another lock cylinder can be installed in the simplest way within the castle. Depending on the design as a full leaf lock or a tubular frame lock, therefore, the execution of the lock cylinder one above the other or side by side.

The locking cylinder of the same design and or the same size can be. It is understood that the lock cylinder also unequal design and unequal size can be performed. Such a lock cylinder is preferably designed as a profile cylinder.

The translationally movable member is formed as a flat slide, which has a running backdrop under a slope. Within this gate, which has latching at their ends, a guide pin, which is located on a bolt shank of the bolt, out. Within the locks the two positions of the bolt are namely extended or retracted set.

In addition to the prescribed functions, the lock also has sensors that provide the ability to detect the individual lock functions by sensors and then forward them to a control unit or monitoring. This is especially for surveillance Such locks necessary if they are used for example in large objects in safety-sensitive areas. In addition, the switching state of such a lock can be queried at any time via the corresponding sensor, which can be configured as a microswitch or Hall sensor or light barrier or the like.

In order to ensure a higher security potential in such high-quality locks, for example, the exclusion of the bolt is monitored from the lock housing, which is also regarded as an indicator that the lock is securely closed. In addition to the monitoring of the bolt but also the already prescribed control is monitored at its shaft via a sensor. Hereby cooperates in the same way the translationally movable member whose position is also monitored.

By monitoring the individual safety-related components of the panic lock ensures that no manipulation of the castle can be made, as well as the failure of individual components or the sensors, if they are not in a specific position or a switching state.

Since such a prescribed self-locking panic lock offers the possibility, in addition to the prescribed opening options on one of the respective independent lock cylinder to open the door, and such lock usually can be operated from the inside via a pusher in conjunction with the nut. This function of operation via the nut is subject to the monitoring by a corresponding sensor.

As the previous description shows, such a self-locking panic lock offers a very high safety standard, since not only his lock functions are monitored, but several at the same time. This ensures a higher security potential, which also shows that manipulation of a lock of this kind is not possible.

The signals obtained via the individual sensors are thereby a control unit, which may be located at the castle or forwarded to another control room.

The invention will now be schematically illustrated and explained with reference to various embodiments in the drawings.

FIG. 1:

A schematic structure of a self-locking door lock with a translationally movable member and two juxtaposed lock cylinder, and a plurality of sensors and an electromagnet;

FIG. 2:

as FIG. 1 , but with a motor drive.

Within a lock housing 1 are located in the FIG. 1 only the actual essential components that are necessary to explain the invention. All other components have been omitted. It will thus affect the function of the illustrated self-locking panic lock in any way. The left lateral conclusion of the lock housing 1 forms a face plate 2, which is broken by a control 5 of a case 4 and a bolt 3.

Within the lock housing 1 is a nut 9, which is equipped with a driver 21 which is connected via a rotatable connection 20 with a member 8 in operative connection. So the nut 9, the one shared Nut may be, remains in its basic position, this spring is loaded by a return spring 22. Likewise, a spring 26 is present, which loads the nut 9.

Within the lock housing there is a first lock cylinder 18 and a second lock cylinder 19. The bolt 3 is guided with its locking shaft 6 via a guide pin 11 within a gate 10, which is located in the translatory member 8. The gate 10 is designed obliquely and has at their ends an upper latch 12 and a lower latching 13. It is clear that by the movement of the translatory member upwards in the drawing of FIG. 1 the bolt is pulled into the lock housing 1 due to the positive guidance on the guide pin 11 within the gate 10.

The arranged above the bolt 3 case 4 is designed doppelschenkelig and in their geometrical dimensions wider than the bolt 3. Following the case 4, a case shaft 23 is present, which is loaded by a spring 24. By the spring 24, the case 4 is always pressed to the outside. In the presentation of the FIG. 1 is excluded case of bolt 3, the case 4 via a case locking member 27, ie the case 4 can not be pressed into the lock housing 1. At the same time, the double-legged trap 4 is stared in this position. Only when the translatory member 8 pulls the latch 3 in the lock housing, the latch shaft 23 is released via the case locking member 27, so that the case can be pressed into the lock housing 1.

Above the case 4 is the control element 5, which is also loaded by a spring 25. The spring 25 always pushes the control 5 out of the forend. The control element 5 has in the interior of the lock housing 1, a projection 29 which cooperates with a locking lug 28 which is located approximately at the end of the translatory member 8. When the latch 3 is retracted in the lock housing 1, the projection 29 engages with the locking lug 28 of the member 8. Thus, the member 8 can not sag back down into the lock housing 1, as it by the projection 29 in conjunction with the locking lug 28th held in this position. Only at the moment when the control element 5 comes into contact with a strike plate, not shown, the control element 5 is pressed into the lock housing against the spring 25. As a result, the control element 5 moves into the lock housing 1 and at the same time releases the link 8.

The translatory member 8 is guided within the lock housing 1 by means of a guide pin 15 in an opening 14. If now causes a rotation of the locking lug on one of the lock cylinder 18 or 19 via a locking lug, not shown, this comes with a driver 16 or 17, depending on the use of the lock cylinder 18 or 19, together and thus raises the member 8 at.

As a result, at the same time as previously described, the latch 3 is pulled into the lock housing 1 and the control element 5 is held by the member 8 on the locking lug 28 and the projection 29.

Like in the FIG. 1 shown, the two lock cylinders 18, 19 are arranged side by side. It is understood that with a change of the translatory member 8 is also possible, the lock cylinder 18, 19 to be arranged, for example, in a tubular frame lock on top of each other, the functions of the castle as such being preserved as a whole.

The FIG. 1 moreover shows an electromagnet 37 whose electrical connections are connected to a plug-in contact 41 which is located inside the wall of the lock housing 1. The electromagnet 37 has a plunger 38 which, for example, with a driver 39th positively and positively connected. The driver 39 acts on a change 40, which is fastened to the nut 9. Now, if the solenoid 37 is energized, which is done by a radio signal or by a command transfer from a control room, for example, selectively open this door with the self-locking, electromechanical panic lock, the plunger 38 is actuated by the electromagnet 37, so that a pivoting of the change 40 takes place. By pivoting the change 40, a displacement of the translatory member 8 is effected, which has the same effect as if via one of the lock cylinder 18 or or if via a pusher, the nut 9 would be actuated. The result is a retraction of the bolt 3 in the lock housing 1 and thus the corresponding door can be opened by pressure, since at the same time the Verstarrung the case after moving the member 8 is released.

Another variant of an electromechanical panic lock shows the FIG. 2 in which instead of the electromagnet 37, a motor 42 is installed with a corresponding gear. At the transmission there is a driver 44, which also acts upon rotation corresponding to the change 40 and thus allows a displacement of the translatory member 8 and thereby causes an opening of the door, not shown.

In addition to the above-described mechanical functions and the structure of the self-locking panic lock according to the invention are the FIGS. 1 and 2 to remove further components. These are the sensors 20, 30, 31, 32. The sensors 20, 30, 31, 32 have different function monitoring tasks of the self-locking panic lock, which will be explained in more detail below.

The sensor 20 dedektiert the Einverfahren or the extended position of the control element 5. It comes, for example, a switching flag 36 to the shaft of the control element 5 and can thus ensure a safe Dedektierung the position of the control 5.

The sensor 32 with its switching lug 33 is located in the vicinity of the bolt shank 6 and thus can dedektieren the retraction or extension of the bolt 3.

Since the translatory element 8 is to be regarded as the central component, its position is also monitored, for example, by a sensor 31 with a corresponding switching lug 34. This shows that, for example, by the operation of one of the lock cylinder 18 or 19, the member 8 is moved upwards, resulting in a deduction on the sensor 31. At the same time, however, this position is also detected when the latch 3 is completely retracted into the lock housing 1. If the translatory member 8 arrived in its upper end position, so it hooks, as already described, with the locking lug 28 on the projection 29 of the control element 5. Upon actuation of the control element 5, that is, the control element 5 is pressed into the lock housing 1 , At the same time the dedication of the sensor 20 via the switching flag 36 is made.

If the prescribed self-locking panic lock is not actuated via the lock cylinders 18 or 19, the actuation can also take place via the nut 9. By pivoting the nut 9 via a pusher, not shown, this operation is also detected via a sensor 30 with the switching lug 35.

As the preceding description makes it clear, in some cases a double monitoring or the dependence of the individual components on each other is detected via sensors 20, 30, 31, 32. It should be noted that other sensors, for example, for monitoring the case 4 or other components still in the self-locking panic lock can be inserted. All dedektierten switching positions or switching movements within the self-locking panic lock can thus be reported to a control unit that allows not only the processing of the individual signals and a display, for example, on a panel. This is necessary especially for large systems with several secure doors via corresponding self-locking panic locks.

For the deduction of the individual switching states or switching functions, it is irrelevant which type of sensors is used. In the present embodiment of the FIG. 1 microswitches 20, 30, 31, 32 with corresponding switching lugs 33, 34, 35, 36 were used. In addition to microswitches, however, it is also possible to use Hall generators or light barriers or other equivalent sensors.
