Abstract

The self-locking panic lock for doors has a spring-loaded, double-armed catch (4), a slide (8) which can move up and down in the lock casing and a latch (3). The latch cooperates with the slide and a spring-loaded locking component (5) fixes it in position when the latch is pushed in. A rotating catch (9) is connected to the slide and two locking cylinders (18, 19) operate it. An independent claim is included for a method for operating the lock.

Description

The invention relates to a self-locking panic lock according to the features of claim 1 and two methods for operating a self-locking panic lock according to claims 15 and 16.

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 installation of the lock, one of the two lock cylinders can be used, through the closing nose of which then an actuation of the lock catch is possible. As already stated, the present door lock for right and left-hinged doors can be used and thus constructed around the central line of symmetry, 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 to other lock cylinders and of course their keys. Such a staggered arrangement of the lock cylinders 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 a change the case can be operated independently.

So is out of the DE 299 05 712 U1 a castle with a major and minor 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 a simple opening from the inside of the room is possible. However, the door is protected against unauthorized opening from the outside. The lock offers the possibility of two Insert lock cylinder. In addition to a primary trigger latch, there is also a secondary trigger latch.

In the EP 0 882 859 B1 a lock fitting system is disclosed which consists of a mortise lock having a latch, a bolt, 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 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, which are prepared for receiving a plurality of keys and thus closing types, are very complicated in their construction as manually operated door locks.

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.

The object is solved by the features of claim 1. The dependent claims provide a further embodiment of the inventive concept again. Further by methods according to claims 15 and 16.

There is provided a self-latching panic lock for a door having a spring-loaded double-legged latch and a slidable longitudinal member of the lock housing cooperating with a latch and a spring loaded control member which locks the member in a latched position with the latch retracted into the latch housing , 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 by a pusher 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 inexpensive to build and includes a drain safety device, which ensures that the case is unlocked only when retracted latch in the lock housing. 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 is solidified, so that due to its geometrical greater width relative to the latch on the latch even with a load on the door leaf no pressure can arise. 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 clear simplification results over the known conventional solutions of the prior art, characterized in that the closing lug of the second lock cylinder acts 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 done automatically forced, so that only the latch assembly must be done via one of the two cylinders. In this case, the double-legged trap is unlocked in an upper end position of the displaceable member. With the opening movement of the door, this unlocked, spring-loaded latch is pushed back into the lock housing and does not need to be retracted 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 most cost effective manner within the castle. 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 lock cylinder may be the same type and / or the same size. 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 in itself under a slope a running backdrop having. 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, namely extended or retracted, set.

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

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. The left lateral conclusion of the lock housing 1 forms a face plate 2, which is broken by a control 5, 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-loaded by a return spring 22. Also, a spring 26 is present, which loads the nut 9.

Within the lock housing 1 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 link 10 is made obliquely and has at their ends an upper latch 12 and a lower latch 13. It is clear that by the movement of the translatory member 8 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 4 is stared 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 4 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 element 5 out of the forend 2. 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 into the lock housing 1, the projection 29 latches 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 1 against the spring 25. As a result, the control member 5 pushes into the lock housing 1 and at the same time releases the member 8 at the same time.

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 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.

In the FIG. 2 an identical self-locking panic lock is reproduced, in which only the lock cylinder 18 and 19 not as in the FIG. 1 are arranged one above the other but next to each other. It is understood that the operation of the translatory member 8 here via the locking lugs, not shown, the drivers 17 and 18 are not stacked lie as in the FIG. 1 but are also arranged side by side.

Basically, the versions of the FIGS. 1 and 2 in that both lock cylinders 18 and 19 can each perform an operation of the lock on an equal basis. There is no dependence between the two lock cylinders 18 and 19.

The FIG. 3 shows a lock housing 1, which is closed with a lock cover 30. In this case, in the lock cover 30, the openings 31 for the corresponding lock cylinder 18 and 19. In this embodiment of the FIG. 3 the openings 31 are arranged side by side. The lock cover 30 is connected via screw 32 with the lock case 1.

The FIG. 4 shows a variant of FIG. 3 , where in addition to the opening 31, an opening 33 is present, which is substantially larger than the opening 31 and thus allows the use of another lock cylinder.

The execution of the translatory member 8 in the FIG. 5 shows this member 8 in a single representation. Here it is once again clear that a closure 8 and thus a movement of the member 8 can be effected via a simple component 8 by the drivers 16 and 17 in the same manner.
