• a lock housing,
• a projecting from the lock housing with a case slope and against spring force in the lock back pressed case which engages in the closed state of the door in a Fallenausnehmung a door frame mountable locking bar and
• a trigger located on the trap,

wherein the release lever is actuated in the course of closing the door of the closing strip such that a locking element is automatically transferred from an enclosed in the lock housing unlocking position in an excluded from the lock housing locking position.

Locking unit means in the context of the invention, in particular an additional locking of an espagnolette lock. Additional latches on the one hand and pusher and / or key-operated central lock are connected in a conventional manner via connecting rods, so that in the course of locking not only the central lock arranged in the central lock, for example, but also arranged in the additional latches locking elements are excluded or excluded can. As a rule, the unlocking is carried out by appropriate operation, for example, manual operation (with key / pusher) and / or Motor operation. The locking of the locking unit takes place automatically and consequently automatically in the closed position reaching door.

Such automatically locking locking units, for. B. additional locks are known in practice. In order to realize the automatic locking, a spring-loaded auxiliary latch can be provided in addition to the actual locking element, which is pushed back in the closed position reaching door leaf to a certain extent in the lock housing and in the course of this Betätigungshubes a spring-loaded locking element is free, so that the locking element then is automatically transferred to the locking position (see, for. DE 100 63 784 A1 ).

A self-locking lock is also from the DE 10 2011 089 418 A1 known. It is equipped with a latch bolt arranged in the lock case, which can assume an open position, a closed position and a locking position, wherein the latch bolt has a latch shaft and is provided with a latch bolt from the closed position into the locking position and striking a frame-side strike plate abutting. The release tongue protrudes from the latch bolt on the opposite side of the latch and, on its side facing the latch, invades the latch latch, it has a bump.

In order to improve the functionality of such mechanically self-locking locks, it has alternatively been suggested that the self-locking be triggered magnetically by means of release magnets (cf. DE 38 01 441 C2 and US 537 775 13 ). A further developed embodiment of such a self-locking lock with release magnets is from the EP 2 096 241 A2 known.

Self-locking locks with magnetic release have basically proven in practice, but they can also be associated with practical disadvantages. Therefore, there is still a need to provide self-locking locking units without magnetic release. - This is where the invention starts.

The invention has for its object to provide a locking unit for a locking system of a door, which is characterized by a simple structure by a proper mechanical self-release. According to a further aspect of the invention, the locking unit according to the invention should be characterized by a high burglar resistance.

To solve this problem, the invention teaches in a generic locking unit for a locking system a door that the trigger lever can be actuated by an integrated in the Fallenausnehmung trigger bar, which divides the Fallenausnehmung in at least two partial recesses. Preferably, the locking element is transferred only when protruding from the lock housing case and (at the same time) pressed by the release bar in the case trigger lever in the locked position. Preferably, the release lever is designed as a linearly displaceable release lever, the z. B. is displaceable in the same direction as the case.

The invention is based initially on the realization that a particularly reliable self-locking can be realized in a mechanical way waiving a trigger magnet when in the (spring-loaded) case a trigger lever is integrated, but not the lock when striking the case against a closing edge edge triggers, but with an integrated into the Fallenausnehmung Trigger bar interacts. The release lever is thus pulled along in the course of pushing back or retracting the case of this forcibly led, z. B. from an integrated into the trap stop. In the above case position, the release lever preferably closes flush with the trailing edge or it returns behind the trailing edge of the trap. In any case, the release lever does not protrude beyond the trailing leading edge in any functional position, so that the trigger lever is in particular not actuated against the outer edge of the closing strip when the case is struck. In the course of closing the door, the trap strikes first against the outer edge of the closing edge with your trap slope, so that the trap is pushed back by the closing strip, whereby the release lever is pushed back with the trap. If the door then reaches the closed position, the latch exits the lock housing again due to the spring force and into the latch recess of the closing strip. However, due to the integrated in the latch recess release bar of the integrated latch in the case can not (fully) enter with the trap in the latch recess, but the trigger lever remains actuated by the trip bar in a pressed-back relative to the trigger position. In this functional position, in which on the one hand the case from the lock housing in the Fallenausnehmung the closing strip and on the other hand, the release lever remains pushed back from the trigger bar in the trap, now an automatic locking of the locking unit now takes place by now the locking element from the enclosed unlocking position in the Excluded locking position is transferred. In this self-locking can be used on known concepts. In particular, a lock chain can be provided in the lock housing, with which the locking element from the locked position can be transferred to the unlocked position and vice versa. In this case, the lock chain can be held in the unlocked position and this unlocking position can then be released due to the described function of the release lever, so that the lock chain is released and the locking element is automatically transferred to the locking position. It can be z. B. on the in the EP 2 096 241 A2 recourse to the concept described.

In any case, reliably ensured by the combination of the invention in the case of the trigger lever with the integrated in the Fallenausnehmung trigger bar that a self-locking then and only then takes place when the door is completely closed, because only then can the trap penetrate into the Fallenausnehmung and only then the release lever against the trailing edge of the trap is pushed back by means of the release bar. Malfunctions are consequently reliably avoided.

From the DE 82 23 124 U1 one knows a frame or a closing strip for such a frame, in the recess of a web is integrated, which divides the recess into two superimposed partial recesses. The trap has a corresponding groove in which engages this web with the door closed. As a result, only the stability of the closing strip or frame in the region of the recess is to be increased. A self-locking is not provided.

It is within the scope of the invention that the trap is designed as a latch bolt, so that this latch bolt at the same time forms the latch and locking element. In the course of self-locking consequently the latch bolt is first pushed back into the lock housing and he then occurs again with the door closed from the lock housing with the case slope. Due to the self-release with the help of the trigger bar, the latch bolt can then be transferred to the locking position.

However, the locking element is particularly preferred as the case of separate latch, z. B. formed as a pivot bolt. Consequently, the locking unit according to the invention is particularly preferably characterized by the combination on the one hand of a spring-loaded latch and on the other hand of an additional locking element, in particular a pivot bolt. Such a configuration has the advantage that on the one hand on the case a high door tightness is generated because of the case (or alternatively also a latch bolt) the door reliably in z. B. a door seal is pulled. The additional bolt, in particular a pivot bolt, then ensures a high burglar resistance. In the unlocked position is the bolt, z. B. pivot bolt, thus in the enclosed position within the lock housing. If the door is closed, the case enters the Fallenausnehmung and due to the release lever, which cooperates with the release bar, then the locking element, for. B. the pivot bolt, extended. In the locked position, the lock is therefore reliably locked on the one hand by the bolt and on the other hand held by the case properly in a tight closed position. It also manages a perfect and reliable self-locking.

Although the invention basically relates to a self-locking lock, there is the possibility that the locking element, for example the pivot bolt, is manually reclocked. There is the possibility that the locking element is properly transferred in the course of the self-locking in the locked position, but that then via a key and / or a motor, a Nachverriegelung takes place, in which the extended locking element is secured against pushing back. In addition, a manual Nachverriegelung, for example by means of a key, be provided in the event that the locking position is not or not properly achieved in the course of self-locking.

The integrated into the Fallenausnehmung the closing strip trigger bar is according to the invention of particular importance. This release bar preferably extends along the closing strip transverse direction and thus transversely to the closing strip longitudinal direction. Particularly preferably, the release bar extends along the closing strip transverse direction over the entire width of the Fallenausnehmung, so that the Fallenausnehmung is divided into two separate and not interconnected Teilausnehmungen. In this case, the trigger bar z. B. are located centrally within the Fallenausnehmung, so that the trigger bar as a central web divides the Fallenausnehmung into two partial recesses identical or substantially identical size. The release bar can be formed integrally with the closing strip. However, the invention also includes embodiments in which the release bar is inserted as a separate component in the Fallenausnehmung or in which the release bar is part of a separate to be fastened to the closing strip release member. In this way, z. B. also be retrofitted existing or conventional closing strips.

Particularly preferably, the locking unit is an additional locking of an espagnolette lock. In such an espagnolette lock the unlocking of the additional locking takes place by means of the drive rods by operating the central lock and / or an electromotive actuation. The locking of the additional lock is carried out automatically in the manner described as soon as the door falls into the closed position. Alternatively, however, the described concept can also be realized with a center lock of an espagnolette lock, so that self-locking is also possible in the area of the center lock. It is otherwise within the scope of the invention that in the course of self-locking the locking element is transferred to the locking position, that then However, a Nachverriegelung via a key and / or a motor takes place, in which the extended locking element is secured against pushing back. Incidentally, the described concept can also be realized with simple, self-locking mortise locks.

The invention is not only the locking unit described, but also a locking unit, which is composed of such a locking unit on the one hand and a closing strip with release bar on the other. The locking unit is therefore particularly preferred also in combination with a closing strip under protection, which has such a trigger bar. Furthermore, the subject of the invention is a locking system with a drive rod lock with at least central lock and at least one additional locking of the type described and with at least one locking strip of the type described.

In the following the invention will be explained in more detail with reference to a drawing showing only one exemplary embodiment. Show it:

the object after Fig. 2 with the door closed in the self-locked functional position.

In the figures, a locking unit 1 in the embodiment is shown as an additional locking of an espagnolette lock. The espagnolette lock consists overall of a central lock, not shown, and usually two locking units 1, of which only one is shown. Central lock and additional locks are usually attached to the back of a (common) lock plate. In the course of a handle operation and / or a key operation, on the one hand, a central lock can be unlocked and, on the other hand, the additional locking mechanisms can be unlocked via the drive rods, not shown. The central lock may comprise a lock latch, a central latch, a lock nut and a lock cylinder in a manner known per se. Details are not shown.

The actuatable via espagnoling additional latches 1 each have a lock housing 2 and a latch 3 and a locking element 4, wherein the locking element 4 is formed in the embodiment as a pivot bolt.

The case 3 protrudes with a case slope 5 from the lock housing 2. The latch 3 can be pushed back against the force of a spring, not shown, into the lock housing, specifically in the Z direction.

The locking unit 1 is thus attached to a door or a hinged door, not shown, while on a likewise not shown, fixed door frame, a closing bar 6 is mounted. When the door is closed, the latch 3 engages in a latch recess 7 of this closing strip 6. The locking strip 6 also has a locking recess 8, in which engages the pivot bolt 4 in the locked state of the lock 1.

The locking unit 1 according to the invention is designed as a self-locking additional lock. For this purpose, a release lever 9 is provided, which is operated in the course of closing the door of the locking bar 6 such that the locking element 4 is automatically transferred from the enclosed in the lock housing unlocking position in the excluded from the lock housing locking position. This release lever 9 is integrated according to the invention in the case 3. Of particular importance is the fact that this release lever 9 is not operated for the purpose of self-locking in a conventional manner by the outer edges of the closing strip in the course of closing the door, but by a special release bar 10 which integrates into the Fallenausnehmung 7 of the shooting bar 6 is and as a central web, the Fallenausnehmung 7 in two partial recesses 7a, 7b shares. The trigger bar 10 extends along the closing strip transverse direction X and thus transversely to the closing strip longitudinal direction Y, in the exemplary embodiment over the entire width of the Fallenausnehmung 7, so that the Fallenausnehmung 7 is divided into two completely separate Teilausnehmungen 7a, 7b. The release lever 9 is in such a way integrated into the case 3, that in the above case position (substantially) is flush with the front edge of the trap 11 and projects in no functional position on this front edge of the trap. The release lever 9 is preferably displaceable in the same direction Z as the trap. He is pulled along in the course of withdrawing or pushing back the case 3 of this case forced, z. B. from an integrated into the trap, not shown stop. When the door is closed, the release lever for the purpose of self-locking of the trigger bar 10 is pushed back behind the trailing edge 11. The interpretation is thus made so that the self-locking then and only then occurs when the case 3 protrudes from the lock housing 2 and at the same time the trigger lever 9 is pressed by the trigger bar 10 in the case 3.

This mode of operation results from a comparative analysis of the Fig. 1 and 2 , Fig. 1 shows the locking unit 1 with the door open with projecting out of the lock housing 2 case 3 and retracted locking element 4. If the door is now swung, the lock 1 enters the region of the locking bar 6, which is attached to the door frame. The latch 3 strikes against the closing edge edge, so that the latch 3 is pushed back into the lock housing 2 along the Z direction. The release lever 9 is retracted with the case 3 (also along the Z direction), z. B. on the not shown, hidden in the case body stop.

As soon as the door is completely swung into the seal, the latch 3 moves into the latch recess 7 (cf. Fig. 3 ). The release lever 9, which is formed in the embodiment as a linearly actuated trigger, it remains in the depressed position, it is pressed by the trigger bar 10 in the case 3. This depressed position of the trigger lever 9 in combination with the extended case 3 now causes the self-locking of the locking lever 4, that is, the locking lever 4 is released so that it is automatically swung out into the locking position. This succeeds without frictional forces between the latch 4 and closing strip 6, since the self-locking takes place only when the door is completely closed and the trap receives the pressure forces of the wing.

The illustrated embodiment with case 3 on the one hand and pivot bolt 4 on the other hand is therefore characterized by a high degree of security at the same time flawless function, because on the case 3, the door is properly pulled into the seal and on the pivot bolt 4 is a particularly secure locking, so that the burglar resistance is increased. Especially the door profile is secured against being pushed apart due to the pivot bolt.

Now, starting from the functional position in Fig. 3 the door is opened, it is first retracted via the door handle (in the central lock) or via a lock cylinder or via a motor, the pivot bolt again. The trap is then retracted so that the door can be opened.
