Description

The invention relates to a driving bolt lock for the inactive leaf of a power wing and a passive leaf having a lock nut for receiving a lock operating handle and at least one bar latch for an up or down from the lock case extendable upper or lower drive bolt bar, and with a Coupling mechanism between the lock nut and the bar bolt, over which the shoot bolt is retracted in a rotation of the lock nut in the opening direction.

There are known closure systems for double-leaf, a wing and a passive wing doors. In this case, the active leaf on a lock with at least one case. Optionally, this lock can also be provided with a latch. The inactive leaf is locked by means of one or two espagnolettes, which engage in the lintel or transom of the frame and possibly in the ground. In order to open the lock of the active leaf in case of need without direct operation of this castle so-called bolt locks are used on the inactive side. In a panic operation of the poppet lock, the upper and possibly the lower shoot bolt rod are retracted and at the same time the latch and possibly the bolt of the swing gate lock are pushed back into the lock box via trigger slide or ejector, so that both wings can be opened.

But such escape doors must be largely tamper-proof. This is to be understood that a manual insertion of the extended Treibriegelstangen must be prevented especially from the outside of the room.

Therefore, there are two types of drive bolt lock, namely a variant with lock for the drive bolt bar, usually the upper drive bolt bar, and a variant without lock. The lock variant is used when burglar resistance is required. The variant without lock is usually used in conjunction with a deflection lock with higher pusher. Both locks are constructed differently and have different components. If you want to change from one version to the other, an exchange of the floating bolt lock is required.

From the DE 10 2004 009 973 A1 a panic lock with a blocking abutment is known, which protrudes at the upper drive bolt slide and meets a locking projection of the lock nut, to prevent that with un-actuated lock nut, the upper drive bolt rod is pressed down unauthorized.

From the EP 1 813 742 A1 For example, there is known a floating bolt lock that drives two floating bolt bars. In order to prevent the floating bolt bars from being displaced without authorization, the lock has a lock gear which is supported on the lock nut.

From the WO 2007/000763 A1 a mortise lock is known, which drives three Treibriegelstangen. In order to prevent the drive bolt rods are moved unjustifiably, the lock on a cooperating with a closure part gear, wherein the closure member in the unactuated state prevents retraction of the locking pin and thus blocks the entire transmission. A displacement of the Treibriegelstangen is prevented.

Starting from a floating bolt lock in the WO 2007/000763 A1 shown type, the invention is based on the object, such a drive bolt lock in such a way that with flexible usability of the lock, the burglary security is increased by manipulation of the drive bolt rods to a particular extent.

This object is achieved with a floating bolt lock of the type mentioned in the present invention, that the coupling mechanism has a pivotally driven by the lock lever lever whose free lever arm is coupled to a first connecting arm of a pivotally mounted two-armed connector whose second connecting arm is connected to the bar latch, said the bar bolt acts on the reversing lever in such a way that it drives the coupling gear counter to the opening direction in the direction of insertion and blocks it.

When the bolt bolt lock according to the invention a pushing back of the bolt bolt is prevented by the insertion of the rod bar directly or indirectly acts on the coupling gear, which is driven against the opening direction and thereby locks. This means that the coupling gear is actuated in the opposite direction and thereby gets into the locking position by the coupling gear comes to rest on a stop. When actuated via the lock nut, the coupling mechanism can only be driven in one direction, namely the opening direction. A drive in the other direction is blocked. But if the drive via the bar latch by this is inserted into the lock case, then the coupling mechanism is moved in the reverse direction and pressed against a stop. Usually blocked. this stop the lock nut and this allows only one direction of rotation.

Further according to the invention a projecting in the direction of the reversing lever or projecting locking element is releasably secured to the bar. This blocking element attempts to actuate the reversing lever against its intended direction of rotation when actuated. The overhang is matched exactly to the required dimensions in the lock case.

Advantageously, the locking element is screwed to the bar bolt, infected or clipped or attached in any other way. In any case, the blocking element is a separate component. This circumstance allows the floating bolt lock according to the invention of a conventional. Lock can be converted into a lock with lock function. The storage of the lock is thereby considerably simplified, since only components for a floating bolt lock and the additional locking element, possibly even for fastening means, must be kept.

To the invention bolt lock housing between the two modes, ie with and without lock function, simply to be able to change without the need to open the lock case, the locking element is mounted with a closed bolt lock housing and removable again. The locking element is advantageously mounted from the back of the lock case, which is accessible for this purpose.

An inexpensive variant of the floating bolt lock provides that the blocking element is plate-shaped and has a pointing in the direction of the reversing lever locking edge. The blocking element is e.g. a stamped part and requires little space in the storage.

On further components can be omitted if the lever has a contact surface or abutment edge for the locking edge for the blocking element. The lever has therefore an additional function, namely the lock function.

In a preferred embodiment of the invention, it is provided that the second connecting arm in the rest position of the lock allows a sliding clearance of the rod bolt in the direction of insertion. About this sliding game the floating bolt can be moved. The game is one to a few, e.g. two or three millimeters. When moving the drive bolt rod, the components of the linkage remain at rest. It is only moved the bar latch within the defined displacement game.

When mounted blocking element, the displacement play of the rod bolt is limited by the blocking element. So the movement is limited to the game.

In known manner, two intermeshing sprocket sections are provided for connecting the lock nut and lever. About this sprocket sections can transmit relatively high forces, but also be supported. The support of high forces is required for the blockage of the floating bolt bar, since this is possibly attacked with a burglar tool.

In a preferred embodiment of the invention, the connection of the lever and the first connecting arm and / or of the second connecting arm and the bar is effected by engaging in longitudinal guides pin. In this way, within the lock box targeted distances can be defined and matched to each other, such as. the catch length of the shoot bolt and the pull-out width of the trap ejector.

Further advantages, features and details of the invention will become apparent from the subclaims and the following description in which, with reference to the drawing, a particularly preferred embodiment is described in detail. In this case, the features shown in the drawing and mentioned in the description may each be individually essential to the invention individually or in any combination according to the claims.

The Figures 1 and 2 show a generally designated 10 drive bolt lock, which is mounted on a cuff 12. The drive bolt lock 10 has a lock case 14, from which the lock cover 88 is removed, so that the Schlosseingerichte is recognizable. In the center is a lock nut 16, which is rotatably mounted and in the direction of arrow 18, a first lever 20 drives (which in FIG. 7 is shown). For this purpose, the lock nut 16 a radially projecting driver 22 which abuts a radially inwardly facing shoulder 24 of the reversing lever 20. In the opposite direction, the lock nut 16 is blocked by a radially projecting nose 8, which abuts against a stop 6.

The first reversing lever 20 is provided with a sprocket portion 26 which meshes with a sprocket portion 28 of a second reversing lever 30 which is rotatably mounted on a bearing 32. Opposite the toothed rim section 28, the second reversing lever 30 has a pin 34, which engages in a bent oblong hole 36 of a connector 40 pivotally mounted on a bearing 38. The connector 40 is constructed in the manner of a two-lever arm, with a first pivot arm 42 extending from the slot 36 to the bearing 38 and a second pivot arm 44 which extends from the bearing 38 to a driving fork 46. In the driving fork 46 engages a pin 48 of a rod bolt 50 which is guided in the longitudinal direction of the floating bolt lock 10 slidably. With this bar bolt 50 is a (not shown) upper drive bolt rod coupled. The bar bolt 50 is shown in its extended rest position, in which it is urged by a coil spring 52.

Furthermore, a Fallenauswerfer 54 can be seen, which is driven along a guide groove 56 from the second lever 30. At the lower end of the lock box 14 is a second bar 58 for a lower drive bar (not shown). This second bar bolt 58 is driven by a second connector 60, which in turn is coupled to a drive arm 62 of the first reversing lever 20. The second connector 60 also drives a latch ejector 64 which is slidably supported along two guide grooves 66.

In FIG. 2 is clearly seen that the upper bar latch 50 is provided with two threaded holes 68 through which a locking element 70, which in the FIGS. 3 and 4 is shown by means of screws 72 with the bar latch 50 is bolted. The blocking element 70 extends parallel to the longitudinal axis of the drive bolt lock 10 in the direction of the second deflection lever 30.

Will the upper bar latch 50, as in the FIGS. 5 and 6 shown displaced by unauthorized insertion of the floating bolt bar in the direction of arrow 74 in the lock case 14, then the blocking element 70 is moved in the direction of the second reversing lever 30 until a locking edge 76 of the locking member 70 abuts a locking edge 78 of the second reversing lever 30. The blocking element 70 attempts to drive the second reversing lever 30 counter to its intended direction of rotation. Since the second reversing lever 30 via the first sprocket portion 26, the second sprocket portion 28 and this drives the first lever 20, the shoulder 24 abuts the driver 22 of the lock nut 16 and exerts a force against the opening direction of the lock nut 16. Since the lock nut 16 is supported with its radially projecting nose 8 on the stop 6, further insertion of the rod bar 50 is blocked. The bar bolt 50 can only about that in the FIG. 3 shown game 86 are moved.

Of the FIG. 2 can be seen that the bar bolt 50 without blocking element 70 can be easily inserted into the lock case 14. The connector 40 can pivot due to the slot 36 without the pin 34 of the second reversing lever 30 is taken. This drive bolt lock 10 thus has no lock function.

The FIG. 7 shows the drive bolt lock 10 with turned locknut 16 in the actuated state. Due to the play 86, the second reversing lever 30 can escape under the blocking edge 76 of the blocking element 70 and the connector 40 pivot, which in turn drives the pin 48 via the driving fork 46 and displaces the bar bolt 50. The lower bar latch 58 is also displaced, ie retracted into the lock case 14 and the Fallenauswerfer 54 and the Liegelauswerfer 64 are pushed out of the lock case 14.

The FIG. 8 shows the bolt lock 10 with mounted lock cover 88. On the back of the floating bolt lock 10 of the bar bolt 50 with the threaded holes 68 can be seen. If required, without the floating bolt lock 10 has to be opened, the locking element 70 are screwed, so that the drive bolt lock 10 receives another, namely the blocking function.
