Description

The invention relates to a self-locking 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 method of installation of the lock, one of the two locking cylinders can be inserted, 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 that consists of a mortise lock having a latch, a latch, a first profile cylinder and a second profile cylinder, which is arranged on the side opposite the forend of the first profile cylinder.

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 relates 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.

The DE 197 13 752 C2 describes a Einstegschloss whose lock bolt by means of a key vor- or rückschließbar. In this case, an electrically actuated, a lock against locking against blocking, provided by means of a linkage locking element is provided. In this case, the invention is directed to the fact that the linkage rotatably encloses a bearing pin which is arranged between the electrical actuating device and the blocking element in the lock housing and can be reset from the blocking position of the blocking element by means of a leg spring which is supported on the linkage and on the other hand on a further pivot pin.

The document DE 196 26 745 C1 discloses a self-locking panic lock according to the preamble of claim 1.

The object of the invention is to provide a simple self-locking 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 still a locking authorization should be repealed.

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

It is a self-locking panic lock for a door, with a spring-loaded double-legged latch and slidable in the longitudinal direction of the lock housing member, which cooperates with a bolt, and a spring-loaded control, which proposes the member set in the lock housing retracted 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 operation 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. But to open such a door again over the castle, there are two possibilities. Either from the inside via a pusher in connection with the nut or from the outside via two independent locking cylinders.

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 prove counterproductive, which means that the bolt always has to be retracted, even if pressure is applied to the lock via the door. 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 drain 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, comes out of the forend control with the Striker in contact and releases delayed after immersing the two-piece 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 acts directly or indirectly on the same member. 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 lock housing. Depending on the design as a full leaf lock or as a tubular frame lock, therefore, the execution of the lock cylinder can be arranged 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 substantially as a flat slide, which has a running backdrop under a slope. Within this gate, which has latching at its ends, a guide pin, which is located on a bolt tail of the bolt, out. Within the locks the two positions of the bolt are namely extended or retracted set.

Such a prescribed lock with two independently operable lock cylinders also provides in the course of the invention, the possibility to shut down one of the lock cylinder, while the second, of course, has a different closing., Can be operated. This would correspond to a so-called master-slave arrangement. Such locks with such a function could be useful, for example, in highly complex locking systems, as they are known from security-sensitive large objects, such as airports, military facilities, government agencies, etc. In case of danger, for example, at the press of a button, all subordinate authorized persons of a building complex could be locked out or even locked up. For this reason, the invention proposes a blocking element which projects at least into one of the closing tracks of the closing nose. With such a blocking element, it is possible to grant certain access authorizations selectively or even in the case of large locking systems, in which one of the two independent profile cylinders can be locked or unlocked.

In this case, the invention provides that preferably the blocking element is located on the translationally displaceable element. In this case, the blocking device preferably has a blocking element which either an electric motor or an electromagnet can be. The armature or plunger is connected to a lever which is designed so that it protrudes in the unlocked state into the closing path of the lock cylinder and thus the locking lug can move the translatory member, while a locked state of the lever does not protrude into the closing path of the Schließzylindemase and thus virtually empty during a closing movement of the closing lug.

In one possible embodiment of the invention, the panic lock may comprise an electric motor, which is designed as an actuating device which causes a translational movement of the member via a rotational translation of any gear. Of course, alternative power transmission members, which are coupled to the member conceivable. The electrical actuating device can be designed in addition to an electric motor as a solenoid, which achieves a movement of the member with when driving.

It is particularly advantageous that the noise reduction of the use of damping means which cooperate with the trap and / or the bolt may be advantageous.

The invention is illustrated and explained schematically with reference to an embodiment in the drawings.

FIG. 3:

shows a detail of a lock according to the invention according to the FIG. 1 with a blocking device in the unlocked state.

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 that the nut 9, which may be a split nut, 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 3 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 is locked in this position. Only when the translatory member 8 moves the latch 3 into the lock housing, the latch shaft 23 is released via the latch locking member 27, so that the latch can be pressed into the lock housing 1.

Above the trap 4 is the control element 5, which is 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 locks 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 nose over one of the lock cylinder 18 or 19 via a locking lug, not shown, this comes with a Driver 17 or a blocking lug 31, 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 already described, the bolt 3 is pulled into the lock housing 1 and the control element 5 is held on the locking lug 28 and the projection 29 via the member 8.

The FIG. 2 shows a partial section of the in FIG. 1 closer described self-locking panic lock. It is contrary to the FIG. 2 only the lock cylinder 18 shown, which cooperates with a blocking device 35. The blocking device 35 is mounted on the translatory member 8 in this embodiment. In this case, in the embodiment, the blocking device 35 preferably consists of a blocking element 32, which includes either an electromagnet or a motor. A plunger 37 of the blocking element 32 is pivotally attached to a blocking lever 36. The blocking lever 36 is designed as an L-shaped lever and has the blocking lug 31 at a free end. The other end of the L-shaped blocking lever 36 is rotatably mounted in a pivot point 33 on the member 8. In this embodiment of FIG. 2 It is clear that the blocking lug 31 is located outside the closing track 38 of the locking lug 30 of the lock cylinder 18. Thus, the lock shown can not be unlocked by the operation of the lock cylinder 18 in this position on the locking lug 30 in conjunction with the driver 16.

In the embodiment of FIG. 3 is in contrast to the embodiment of FIG. 2 the blocking nose 31 is retracted into the closing track 38 of the closing nose 30. This shows that the Schüeßnase 30 coincides with the blocking lug 31 and thus can be done via the lock cylinder 18, an actuation of the lock, because by the locking lug 30, the member 8 is translationally moved.

In this position, the blocking device 35 of the blocking lever 36 in the. Schließbahn 38 has been moved, that is, around the pivot point 33 of the blocking lever 36 has been pivoted. So that the path of the blocking lever 36 is limited, it is at least one side against a stop 34. This ensures that the path of the blocking lever 36 is limited.

As the description shows, with such a self-locking panic lock, which is equipped with two lock cylinders 18, 19, which can be operated independently, also the subsequent authorization of the two lock cylinders 18, 19 are classified. In this case, for example, according to the master-slave principle, one of the lock cylinder 18, 19 always be accessible, whereas a second can be locked accordingly. By such a construction, it is possible to design locking systems with high-quality self-locking panic locks in an inexpensive manner.

Furthermore, it should be noted that the blocking device 35 can also be subsequently attached to the blocking lever 36 to the translatory member 8. In one embodiment of the blocking element 32 as an electromagnet this is preferably designed bistable.
