Description

The invention relates to a locking device according to the preamble of claim 1.

With the EP 0431369 A2 is a mortise lock with a latch bolt has become known. This latch bolt has in addition to the task of a conventional trap the task of locking the door in addition, which is caused by the fact that the latch bolt automatically goes after closing the door of a trap position in a locking position in which it is further ejected from the mortise in the case position and thus far into the door frame-side strike plate engages. As a rule, such a latch bolt can no longer be pushed back into the slot between the door and the door frame by inserting a tool. A door with such a latch bolt is automatically locked after closing.

From the DE 29605517 U1 Already a locking device is known, which also provides secondary lock boxes in addition to a main lock, the latch bolt according to the EP 0431369 A2 contain.

From the DE 202013009209 U1 a castle is known in which the main lock trap according to the EP 0431369 A2 is designed and in which the vortretendende latch bolt releases an espagnolette, which is subjected to force in its locking position.

The disadvantage here is that a door with one of the aforementioned locking devices in everyday life causes difficulties in handling, since the doors each completely lock when they reach the plant to the frame. However, this is only really desirable in limited periods of time, for example, when heavily frequented buildings should always be secured after a certain period of time and only authorized persons should have access. In periods with high public traffic, however, it is often sufficient if the locking device is secured with its trap function and can be opened with an electric door opener, or secures the release position (daily switching) of the electric strike. In the last-mentioned periods, there are sufficient authorized persons to protect the building and protection against the effects of weather is sufficient. In addition, it should be noted that in a lock that is constructed in the manner of a latch bolt lock, the case after actuation of the trigger in its locked position precedes and is secured against pushing back. Therefore, the combination of one or more electric door openers and a latch bolt lock is not possible. If, in addition to the case, further latches are actuated, eg in secondary lock cases, remote operation is only possible with an electric lock drive. Therefore, there is a need for a lock whose automatic function can be selectively switched on or off.

Also known are other trap locking devices. That in the DE 19748444 A1 described lock has a case that is stored in a trap window a cuff rail. The trap can be withdrawn from a trapping position in which most of the case head is in front of the faceplate, into a trap retraction position in which the trap is fully retracted into the trap window. On the back of the faceplate is a trap lock in the form of a pitch disc, which can be switched back and forth by turning on an axis of rotation between a locking position and a release position, this case lock can hold the case in the back-closed position.

From the DE 4015881 C2 a lock is known in which the case is lockable in a case trailing position by means of a lever arm.

The DE-PS 691398 discloses a latch lock in which the latch is retractable by a knob so that a pin connected to the knob, which acts on the latch on the latch tail in a control slot spring loaded behind a locking projection occurs, so that the trap can only occur again by pressing the knob ,

The DE 8909119 U1 shows a lock in which the case by the change by means of a key operation by a differential range further retractable than by means of a handle operation. Within this range of differences, a locking means for the case can be brought into locking engagement and holds the case in the retracted position.

The DE 102007044324 B3 has a lock on the subject, which provides a locking member for the purpose of catch locking, which provides an operable from the faceplate forth actuating portion and engaging the latch tail locking portion.

The EP 0801193 B1 shows a mortise lock with a trap having a locking latch in the case head. The locking bolt can be moved in retracted case behind the faceplate and thereby prevents the passage of the case.

In the EP 0682167 B1 a change is provided, which acts via a coupling on the follower on the case. For this purpose, the pusher has a separate lever, which shifts the trap, as soon as the pusher is set in motion over the change, in its retracted position. Thus, the case can be permanently held in their retracted position, this mortise lock on a Fallenarretiereinrichtung, which consists of a return path on the change with an associated mounted on the lock case lock stop, the lock stop moves against the movement possibilities of the change in the way back the return path, to prevent the change on his way back to the base position can go back. The barrier stop consists of a two-armed lever, which is mounted as a rocker fixed to the lock case and is offset from the cam of the lock cylinder in rotation in the closing direction in its locking position.

In this mortise, the setting of the case is therefore carried out by a rotation of the follower until the case is moved to its retracted position and then activating the lock stop on the key. For this purpose, the key must be turned in the closing direction, so that the barrier stop is shifted with the associated arm in the return path of the return path barrier. Although such a mortise lock has a complicated structure, and can not be used for doors with increased safety requirements, since only one bolt and the trap are provided.

In contrast, the operation of the mortise lock according to EP 0410122 B1 Relatively simple, since there the case retracted on the change case is locked by simply pressing an accessible from the cuff side of the mortise lock forth pressure bolt. However, this mortise has a relatively complex structure, since in particular the change must be made in two parts. This mortise lock is incompatible with the requirements for a secure locking of a multi-point lock.

In addition, the latter embodiments dwells the disadvantage that they must be activated and deactivated separately for each latch bolt and are therefore not suitable for secure locking with a multiple lock.

There is therefore the desire to combine either automatic and secure locking on the one hand with easy handling and opening function at certain times.

To solve this need, the invention provides a locking device according to the preamble to the realization of the features stated in the characterizing part of claim 1. The device created thereby can be easily adapted to the respective needs and requires only fewer components. The arrangement of the control element on the main lock facilitates handling.
A structurally simple further development provides that the locking lever is arranged in a main lock bolt and essentially forms an actuating arm and a locking arm as a pivotable two-armed lever.
An unobtrusive arrangement is achieved when the operating lever protrudes in front of the end face of the bolt.

For the simple design of the main lock can be provided that the drive rod in the main lock housing is effective as a drive rod slider, which carries a cooperating with the locking lever in the blocking position stop.

Fig. 1 shows a locking device 1 with a main lock box 2 and two secondary lock boxes 3, which are identical. A drive rod 4 connects the main lock case 2 and the secondary lock boxes 3. At the main lock case 2, a main lock bolt 5 and a case 6 are provided. Main lock bolt 5 and 6 occur in the illustrated locking position of the locking device 1 in front of a forend 7, which forms an end face of the main lock box 2 and the secondary lock boxes 3 and which the drive rod 4 provides a cover and guide.

When the locking device 1 is an automatic lock, which automatically enters from a standby position in a locking position when the wing comes to rest on the frame. The drive rods are free falling. The espagnolette in the secondary boxes is spring-loaded, as will be shown below are held in the standby position fixing.

The Fig. 2 shows that the main lock box 2 a pusher 8 is provided for coupling with a pusher, not shown here. The lock can be operated via the pusher or the pusher nut 8. A cylinder bore also allows the attachment of a lock cylinder 9 for further operation. The lock cylinder 9 can act on the driver 10 on a pressure piece 11. The pressure piece 11 is connected to an extension 8 ', which forms an arm 12 and 13. The Extension 8 'is rotatably mounted on the follower 8. Thus, if the thrust piece 11 is displaced over the driver 10 in an upward movement, then the extension 8 'rotates on the follower 8 and thus engages in a retracting manner on the catch tail 14.

The case 6 is thereby behind the not shown here 7 ( Fig. 1 ) withdrawn. At the same time, the Nussarm 12 acts with a stop 15 on an extension piece 16 of a drive rod 17, which thereby from the in Fig. 1 shown closure position reaches up into its unlocked position.

At the latch tail attacks a latch spring 18 and urges the case 6 in their trap position in which they accordingly Fig. 1 in front of the forend 7

By operating the pusher 8 and the interaction of the Nussarms 12 with the extension piece 16 of the espagnolette 17 is also moved upwards. In conjunction with the FIGS. 8 and 9 It is clear that in this case also arranged in the secondary lock box 3 case, which is designed as a latch bolt 19 is withdrawn. An espagnolette 20 displaceably mounted in the secondary lock case 3 acts on the latch bolt tail 22 via a latch lever 21.

The latch bolt 19 is provided in a known manner with a trigger 23 which fixes the freely retractable latch bolt 19 in a normal case position by engaging behind the forend 7. Does the trigger 23 to rest against the frame side provided in the striking plate trap entry opening, the latch bolt 19 is advanced by loosening the fixation in its locking position. For the construction and operation of the shutter is fully incorporated by reference to the DE 202013009210 U1 which discloses the trigger on a main lock latch, but is functionally identical in terms of its fixation and release.

If the latch bolt 19 protrudes from its latch position into its latch position, the fixation of the secondary latch bolt 24 effected on the latch bolt tail 22 is canceled. This executed in the embodiment as a pivot bolt secondary lock bolt 24 is subjected to a spring-loaded slide 24 'in its latch pivot position. The slider 24 'is loaded Force memory in unlocking the Nebenschlossriegels 24 fixed. and is forced back to its fixed position upon upward movement of the espagnolette 20. At the same time the secondary lock bolt 24 is pivoted back into its unlocked position.

At the main castle is after Fig. 1 and 2 a main lock bolt 5 is provided. This is not drivingly connected to the espagnolette 17. The espagnolette 17 is drivingly connected to the drive rod 4, which is thereby effective in the main lock case as espagnolette 17. The main lock bolt 5 can be preconnected via the lock cylinder 9.

From the Fig. 4 It can be seen that on the main lock case 2, more precisely in the main lock bolt 5, a locking lever 25 is mounted. The locking lever 25 is designed with two arms and forms a pointing in the direction of the end face 26 of the main lock bolt 5 actuating arm 27 and a locking arm 28. The locking arm 28 includes a pawl 29 with which the locking lever 25 engages under a locking projection 30 which is attached to the espagnolette 17. It can be seen that the assignment of the locking lever 25 can take place only in the retracted position of the main lock bolt 5 and Fallenrückzugsstellung of the espagnolette 17, in which the espagnolette 17 is displaced maximally upwards. The locking lever 25 thus prevents the espagnolette 17 down ( FIGS. 2 to 4 ) can be relocated. Thus arises at the secondary lock case, the in Fig. 9 shown functional position. The latch bolt 19 is retracted and can not protrude beyond the forend 7. The case 6 of the main lock case 2 remains in its Fallenfunktionsstellung and can thereby fix the wing of the door in a leaning on the frame position.

Based on this, a user can be withdrawn by handle operation, the case 6 or make the case 6 ineffective by operating an electric door opener. The user can over the key the main lock bolt 5 accordingly Fig. 5 precede, wherein the locking lever 25 is laterally removed from the locking projection 30 and thereby the espagnolette 17 is released. As a result, the latch bars 19 are released and advanced via the drive rod 4. Upon entering the frame-side strike plates of the trigger 23 is actuated and the latch bolt 19 occurs in its locked position.

Thus, the secondary lock latch 24 is released and locks. The door can now be unlocked only via a key operation, since the main lock bolt 5 is movable only on the lock cylinder 9. This is an effective child safety is given, in which an undesirable opening from the inside of the door should be avoided. When the door is open, the main lock or the main lock case 2 can be made accessible again and the actuating arm 27, which projects in front of the end face 26 of the main lock bolt 5

From the FIGS. 6 and 7 the structure of the main lock bolt 5 emerges. This is provided with a taper 31, from which protrudes a bearing pin 32, which serves for the storage of the locking lever 25. A cover plate 33 protects the locking lever against undesired influences and also compensates for the taper 31, so that in the closed position of the main lock bolt 5 whose end face 26 fills the passage opening in the forend 7 The actuating arm 27 projects only slightly and unobtrusively over the end face 26.
