Abstract

The invention relates to a lock, in particular an espagnolette, having at least one latching bolt (10), which is forced in the advancement direction by a latch spring (16) and, in a first latch-advancement position, in which substantially just one latch-head portion having the latch slope projects beyond a lock-case-front rail (25), is retained by a releasable arresting member and extends from said first latch-advancement position, following return displacement of the latch and release of the arresting member, into a second latch-advancement position, in which a bolt portion which follows the latch slope emerges in front of the lock-case-front rail (25), wherein the latching bolt (10) is assigned to a secondary lock case (3), which can be actuated by driving rods by way of a main lock, and the secondary lock has a bolt (11), which can be actuated by separate driving-rod slides (13). In order to achieve straightforward but, as it were, secure locking at a distance from the main lock, provision is made for the arresting member to be a lever which is mounted in a pivotable manner in the latching bolt (10) and has an arresting nose (32), which exhibits the arresting element (31), and for the arresting element (31) to retain the latching bolt (10) in a partially extended intermediate position and for a blocking means (35) of a force-activated slide (17), which is mounted in the secondary-lock housing (12) such that it can be displaced transversely to the latching bolt (10), to be active in said intermediate position.

lock

The invention relates to a lock according to the preamble of claim 1. A generic lock is already known from EP 0995866 B1. The well-known lock, is a espagnolette lock with an acted upon by a latch spring in the forward direction trap in a secondary lock. The trap sticks out in a first

Fallenvortrittsstellung only with a case slope having case head section on the Stülp before and is held by a releasable locking member. From this first case trailing position, the case after Fallenrückverlagerung by contact with the frame-side strike plate and release of the locking member in a second

Fallenvortrittsstellung moved forward. If the trap is moved forward, a bar driven by means of rods can be preconnected. The disadvantage here is that the locking of the bolt must be initiated manually, so that includes the case latch in a conventional operation, but not the bolt of the secondary lock.

From EP 0798436 B1 it is known to provide a latch bolt in a secondary lock with a pivotally mounted in the case head locking element, which limits the case leading in a first case trailing position with a locking edge. When dipping the latch bolt in the trap entry opening of the frame-side strike plate is the

Relocated locking element and the locking edge releases the case entrance. Another, a burglary aggravating bar is not provided.

From EP 0431369 A1 a trigger for a mortise lock is known.

It is also known from the leaflet "GU-Secury- superior safety through multi-point door locks", distributed in 1997, to use the latch bolts of the secondary locks for DIN right and left-hand wings by reversing the latch bolts The triggers are constructed in accordance with EP 0431369 A2. The DE 202013009209 U1 has a multi-point locking in the subject, in the

Main lock box is provided a shutter with trigger and where the trap is a

Locking device for a spring-loaded drive rod forms, by lifting the drive rod and the associated latch of the secondary locks get into the locked position. A similar embodiment is also known from DE 202013009210 U1, whose focus is on the design of the trigger. A disadvantage of these latter locks is that the triggering of the main lock latch does not necessarily lead to the inclusion of the secondary lock bolt, since the wing are not reached due to a distortion in Hauptschlossfernen wing sections to rest on the frame. The bars are triggered, but can not intervene, as bar and bar entry opening are not opposite.

The invention seeks, starting from the aforementioned EP 0995866 B1 for a simple but almost secure locking each secondary lock at a distance from the main lock. To solve the invention, the invention provides that the locking member is pivotally mounted in a latch bolt lever having a locking element having locking lug and that the locking element holds the case in a partially extended intermediate position and in this intermediate position a blocking means of a force transversely to

Fallen bolt in the lock housing slidably mounted slide is effective. The invention thus displaces the trigger and the bolt in a common secondary lock and arranges them spatially after each other. The trap, which acts as a latch bolt, provides a secure locking mechanism that can not be pushed back with any aids and that offers resistance to vertical wing movement. The trigger is simple and inexpensive to produce. Each secondary lock is thus self-sufficient and locks even if, due to a partial distortion of a partial area, its latch can not lock because the latch bolt and latch opening do not lie in front of each other.

A further embodiment provides that the slider is associated with a finger a pivot bolt, since such interaction is ensured. The combination of a

Fallen bolt and a pivot bolt gives a high security against burglary.

It can also be provided that the finger is assigned to the pivot bolt in its unlocked position on an edge extending obliquely to the displacement direction, so that the pivoting movement can be realized in a simple manner. In order to allow the Vorschließ and the retraction of the pivot bolt, form the edge and a nose two in the pivoting angle of the pivot bolt extending control edges, which cooperate with the slider. Further advantageous embodiments will be apparent from the figures. It shows:

1 is a lock in an overview,

2 shows a secondary lock in an enlarged view in the ready position,

3, the secondary lock according to Fig. 1 in the locked position,

4 shows the secondary lock according to FIGS. 2 and 3 with pusher or key operation of

Main castle and

4a is a bottom view of the secondary lock of FIG .. 4

Fig. 1 shows a locking device 1 in the form of a lock with a

Main lock box 2 and two secondary locks 3, which are identical. A

Drive rod 4 connects the main lock case 2 and the secondary lock boxes 3. At the main lock box 2, a latch 5 and a latch bolt 6 are provided. The latch 5 and the latch bolt 6 occur in the illustrated locking position of the locking device 1 in front of a Stülp 7, which forms an end-side conclusion of the main lock box 2 and the secondary locks 3 and which the drive rod 4 provides a cover and guide.

The locking device 1 is an automatic lock, which automatically moves from a standby position into a locking position. For this purpose, the drive rod 4 is in its locking direction gravity or spring loaded and, as will be shown below, held in the ready position fixing. At Hauptschlosskasten 2 a pusher 8 is provided for coupling with a pusher, not shown here. The lock can be operated via the handle. A cylinder bore 9 also allows the attachment of a lock cylinder for further operation.

The secondary lock 3 shown in FIG. 2 is in the ready position and, in addition to a latch bolt 10, includes a pivot bolt 11. In the secondary lock housing 12, a drive rod slider 13 is slidably guided and coupled via a coupling 14 with the drive rod 4. Furthermore, the secondary lock housing 12 supports a pivotable two-armed

Change arm 15 and a leg spring 16, which is effective as a trap spring. A slider 17 is supported by a spring 18 on the secondary lock housing 12 and acts with a finger 19 together on the pivot bolt 1 1 which is pivotally mounted on an axle 20. For this purpose, the finger 1 9 is provided with a direction of displacement 21 of the slider 17 inclined contact bevel 22. The slider 17 has a reaching to the finger 19 back 23, which is associated with the rear wall and from which extends next to the finger 19, a hook 24 in the direction of the faceplate 25. In the resulting bay 26 of the latch tail 27 and an attached thereto stop piece 28. At the stop piece 28th engages the leg spring 16 and kraftbeaufschlagt the latch bolt 1 0 in the direction of the faceplate 25. The espagnolette 13 has an angled in the direction of the hook 24 cam portion 29 which projects into the sliding portion of the slider 17. The stop piece 28 has an open-edged trough 30, in which the change arm 15 engages. In the illustrated ready position, a locking element 31 of the latch bolt 10 is supported by a locking lug 32 on the faceplate 25 and projects with a release finger 33 in front of the faceplate 25. With a locking projection 34, the stopper piece 28 abuts against a detent 35 of the slider 17 and blocks it. As a result, the pivot bolt 1 1 is prevented from performing a pivoting movement.

If the wing is closed, to which the lock is assigned, the latch bolt 10 is first urged into the secondary lock housing 12 via a latch bevel which abuts the frame or the strike plate fastened thereto. If the wing pressed so far to the frame that the latch bolt 10 can dip into the latch opening of the strike plate, then the trigger finger 33 by contact with the strike plate in a known manner lever out the locking lug 32 and the latch bolt 10 due to the leg spring 16 in the in Fig 3 precede position shown. As a result, the release of the catch 35, since the

Stopping piece 28 is pre-displaced with the locking projection 34. The catch 35 forms

Blocking means for the slide 17.

The thus released slide 1 7 is displaced by the spring 18 in the drawing down. In this case, by applying a relative to the back 23 perpendicularly extending projection 36 at an edge 37 of the pivot bolt 1 1 this swung out. This is made possible by the eccentric and in the direction of displacement of the slider 17 arrangement of the edge 37. In the locking position of the pivot bolt 1 1, the slider 1 7 is on the one hand with the projection 36 on the edge 37, on the other hand with his

Housing wall 38 facing back to the secondary lock housing 12 at. As a result, the pivot bolt 1 1 is locked against pushing back. Due to the pivotal movement of the pivoting bolt 1 1 reaches a nose 39, which is in extension of the edge 37, in the displacement of the projection 36. The Vorschließen and the closing of the

Pivoting bolt 1 1 is made possible by the fact that the edge 37 and the nose 39 form two in the pivoting angle of the pivoting bolt 1 1 extending control edges, which cooperate with the slider 17. In addition, it can be seen that the change arm 15 with its second arm 40 and one of them pointing perpendicularly in the direction of the lock bottom tooth 41 in the drawing is almost horizontal and in the region of the driver portion 29. The with the

Locking device 1 equipped door is locked in this functional position. The unlocking of the door is done by the main lock on the drive rod 4 and the

Espagnolette 13. This will be key operated or push-operated from the position shown in Figs. 2 and 3 illustrated basic position in the drawing shifted upward. As a result, the tooth 41 comes to rest on the driver portion 29, whereby finally the change arm 15th

is pivoted. This engages with its second arm in the trough 30 of the stopper piece 28 and pulls this back together with the latch bolt 10. As can be seen in FIG. 4 a, at the same time the drive rod slide 13 engages with a driver hook 42 to the slider 17 and takes this with. In this case, the spring 18 is tensioned and finally the latch bolt 10 is retracted by further rotation of the change arm 15 in the secondary lock housing 12. The door can now be opened.

If the pusher or the key is returned to its normal position, the functional position of FIG. 2 is restored.
