Abstract

The additional lock assembly (3) incorporates a sliding bolt (10) which can be pushed back freely and which can be moved beyond the normal position into a locking position by a spring (28) and/or by a gear (111,136,132). The sliding lock from a locking device (24) may, on closure of the door, punch through the lock plate (33) in the door frame on the other side of the lock. The sliding bolt may be held in position by a catch. When the door is closed, the catch may release the bolt so that the bolt takes up a locking position, while it passes through an aperture in the lock plate. This lock plate may be mounted in the door opening. The catch can hinge in a plane which lies at right angles to the hinge axis of the door and may be forced outward by a spring loaded lever (30).

Description

The invention relates to a locking device for a Door, a window or the like, with a Main lock box, at least one additional lock box and at least one the additional lock box with the Main locking box connecting connecting rod, according to Features of the preamble of claim 1.

A drive rod lock is known from DE 35 05 379 C1 which has a connecting rod with a Middle lock is connected. So this connecting rod connects the two latches of the two locks. That way a door not only in the middle, but also in the area of it Corners are connected to the striking plate on the door frame side. When the door is closed, the latches are released via the striking plate inserted so that the door is in its closed position can. To open the door, the latch of the middle lock actuated via a handle or a locking cylinder and withdrawn, this movement over the drive rod the espagnolette lock latch is transmitted so that this trap is also pushed back. It is disadvantageous that with the insertion movement of the trap always the Driving rod is moved. This leads to stiffness the trap and malfunctions.

EP 431 369 A2 is a mortise lock with a Latchbolt has become known. This latchbolt has besides the task of a conventional bolt the task of the door to additionally lock what is caused by the fact that the Latchbolt after closing the door of one Latch position automatically in a locking position passes, in which it continues from the mortise lock is pushed out as in the trap position and thereby far engages in the striking plate on the door frame side. Such a The latch bolt can usually no longer be inserted a tool in the slot between the door and the Door frames are pushed back. A door with one The latch bolt is automatically locked after closing.

From EP-A-0 431 369 is a main lock with a Latch latch known in which the trap after closing the Automatically locks the door into the striking plate.

The invention has for its object a locking device to be provided with additional lock boxes with which the door offers better burglary resistance that Trap function improved and in addition the number of preceding components is low.

This object is achieved by a locking device solved, which has the features of claim 1.

As soon as the latch bolt takes up its locking position, the latch lock lever is moved so that its latch lock edge the latch bolt in the locked position guaranteed. Only then can the latch bolt be moved take place when the rear grip of the trap's locking edge Latch lock lever is lifted.

With the locking device according to the invention Door off center, i.e. at least in the area of a corner held over the latchbolt and also locked. One falls with the locking device according to the invention equipped door in the lock, then first the latch bolt pushed back over the striker plate on the door frame, which enables the door to be closed. Is located the door in the closed position, the latch bolt is released from the Additional lock box pushed out and goes over its latch position out into a locked position. In this situation the latchbolt can e.g. by inserting a flat Tool in the gap between the door and the door frame not be pushed back. Such a locked door offers high resistance to burglary.

It is particularly noteworthy that the latch bolt at open door of a locking element in the latch position is held so that the door closes easily can be. Only when the door is in its closed position the locking element releases the latch bolt, so that this beyond the latch position by about a further 10 mm to 15 mm emerge from the additional lock box and into the striking plate on the door frame side can intervene. The release the latch bolt through the locking element takes place automatically then when the door is in its closed position, because then that Locking element from the striking plate on the door frame into the Release position is pushed. The automatic extension of the The latch bolt is triggered by the striking plate.

In a further development it is provided that the locking element in a normal plane to the pivot axis of the door is pivotally mounted in the latch bolt. The locking element So has a parallel to the pivot axis of the door Swivel axis so that it hits the striking plate can dodge. In the rest position, the locking element protrudes partly the contour of the latchbolt.

The locking element is preferably via a spring-loaded Lever pushed in the direction of extension. From this Extension direction in which the locking element the contour of the The latch element protrudes, the locking element can counter the Force the spring-loaded lever to a position inside the contour of the latch bolt are inserted, and will thereby ineffective.

In one embodiment, it is therefore provided that the locking element of the latch bolt in the latch and Locked position is pushed. The spring-loaded lever which pushes the locking element in the extension direction even with the door open, extend the latch bolt in its latch position and with the door closed in its Locking position.

The latch bolt preferably points to the ramp slope opposite side and in the area of the trap tail a projection on which a latch return lever engages. The latch bolt is activated via this latch reset lever either from its locked position or from its Latched position retracted to open the door allow. The latch reset lever is so with the Connecting rod connected to it when pressing the connecting rod taken into the closing position by the drive rod becomes. When moving to this closed position the latch reset lever completely into the latch Additional lock box.

Several additional lock boxes can be used with the drive rod the main lock box so that the individual Latch bolt of the additional lock boxes synchronously over the Push rod pushed into the respective lock box become. The use of multiple lock boxes across the height the door also prevents the door from warping and reduces additionally the risk of break-in.

The latch return lever is preferred when the door is closed and inserting the latch bolt pivoted by this and is uncoupled from the drive rod. When closing the door so only the latch bolt is inserted, however not actuated the drive rod.

The latch return lever is preferably one Door leaf level of the vertical axis pivoted. To this The latch reset lever sets the way when moving the Driving rod in a parallel to the pivot axis of the door Directional thrust in an orthogonal, in shear force with which the Latch bolts are drawn into the additional lock case can.

According to a preferred embodiment, Latchbolts on a latch lock lever that when fully extended latch bolt this in the Locked position locked. This latch lock lever prevents the in the locked position latch bolts e.g. about a tool which is inserted between the door and the door frame or even if the door frame is damaged and exposed Latch bolt inserted into the additional lock case can be.

A particularly preferred embodiment provides that the latch return lever has a nose that when Actuate the latch reset lever using the drive rod the latch lock lever from its locking the latch bolt Position and the latch bolt to retract releases.

So the latchbolt is in its Locking position and is in via the latch lock lever secured this position, then by pressing the Drive rod of the latch return lever with which the latch bolt is pushed back into the additional lock box, and the Latch lock levers are lifted out of their locked position, before the latch is withdrawn.

The latch lock lever can move one to the door leaf vertical axis be pivotally mounted. In addition, the Latch lock lever with one in the locked position urging spring, in particular a leg spring, connected. As a result, when fully extended Latch latches of the latch lock levers automatically Takes locking position and the latch bolt against Push back locked.

A decoupling of several latchbolts is achieved that the latch bolt is pushed back when the door is closed and is out of operative connection with the drive rod. This Design has the advantage that e.g. by pushing in a tool in the gap between the door and the Door frame the one in the latch position The latchbolt can be pushed back, but it does does not automatically push the other latchbolts back become. The decoupling continues to increase the Burglary.

In one embodiment of the invention, that the latch bolt is designed as a swivel latch bolt. In this embodiment, the latch bolt becomes non-linear pushed out of the lock box, but by one Swiveled axis rotated, with the rotational movement from the Lock box emerges. This swing latch is pivotable according to a swivel bolt.

The latch bolt is preferably electromagnetic retractable. In this way e.g. with a electric door opener the door can be opened by all Latchbolts at the same time in a known manner withdraw a magnet.

The main lock box preferably also has one Latchbolts, a bolt and / or a trap. In The main lock box can also be developed further be designed as a panic lock.

Further advantages, features and details result from the subclaims and the description below, in the particularly preferred with reference to the drawing Embodiments are shown in detail.

a view of Figure 3 with retracted in the additional lock case.

The one shown in FIG. 1 and overall with 1 designated locking device consists of a Main lock box 2 and two additional lock boxes 3. The Lock boxes 2 and 3 are attached to a lock cuff 4. The main lock box 2 has a box lid 5 closed and there are a follower 6, a Lock cylinder 7, a latch 8 and a bolt 9 can be seen. The trap 8 is in the trap position, so that it of a striking plate 33 shown in Figure 6, which is located on the door frame, in the main lock box 2 can be pushed in. The bolt 9 is in the closed position. The additional lock boxes 3 are also provided with a trap that acts as a latch bolt 10 are trained. The latchbolts 10 are also in their latch position and can thus by a striking plate 33 are pressed into the respective additional locking box 3. Finally, a drive rod 11 can be seen, the Main lock box 2 connects to the additional lock boxes 3.

In the view of the Main lock box 2, the box cover 5 is removed, see above that the lock mechanism is recognizable. For example, the from Lock cylinder 7 actuated change 12, the one Bolt 13 on a slide 14 of an arm 15 one Control nut 16 attacks, recognizable. The slide 14 acts on a sliding stop 17 on one Control plate 18 is attached. In this control plate 18 is the drive rod 11 hooked in at 19. The control nut washer 16 has a further arm 20 which on a trap foot 21 of the Trap 8 is present.

If the lock cylinder 7, the change 12 and this the control nut disc 16 in the clockwise direction actuated, then the arm 20 and the latch foot 21 Trap 8 moved into the main lock case 2. This can however, also take place in that the follower 6 by means of a pusher, not shown, in the direction of Is operated clockwise, the follower 6 the Take control nut 16 in its rotational movement. Moreover is when the lock cylinder 7 or the The follower 6 of the slide 14 and the control plate via this 18 relocated, whereby the drive rod 11 is actuated.

With this drive rod 11, the additional lock box 3 is in accordance with Figure 3 connected. In this, shown without box lid Additional lock box 3 is the latch bolt 10 in the direction of Cutting line slidably supported. This latchbolt 10 is in the case of Figures 3 and 4, in the latch bolt 10 with its run-on slope 22 (FIG. 4) the castle cuff 4 dominates.

FIG. 4 also shows that the latch bolt 10 with one running in its longitudinal direction, one-sided open groove 23 is provided. Located in this groove 23 a locking element 24 which is pivotable about an adapter sleeve 25 is stored in the groove 23 and thus in the latch bolt 10. This locking element is with a locking lug 26 and one Trigger nose 27 provided.

In the trap position, which is shown in FIG. 4, engages behind the locking lug 26, the lock cuff 4 and prevents further extension of the under spring force standing latch bolt 10. This spring force is from a Trap extension spring 28 (Figure 3) applied to a Spring guide pin 29 is pushed on and on the one hand the inner wall of the housing of the additional lock box 3, on the other hand supported on a latch extension lever 30. This Trap extension lever 30 is pivotable in a bearing 31 stored. The end of the bearing 31 opposite Latch extension lever 30 engages on the trigger nose 27 opposite end of the locking element 24 and urges this under the force of the latch extension spring 28 in Out direction. Because the locking element 24 via the adapter sleeve 25 is connected to the latch bolt 10, this is also in Extending direction pushed.

In Figure 4 it can be seen that the latch extension lever 30 indeed attacks on the locking element 24, the direction of the force of the Fall ejection lever 30, however, not by the Adapter sleeve 25 formed pivot bearing of the locking element 24 goes, so that the latch extension lever 30 has a pivoting moment exercises counterclockwise on the locking element 24. Because of this pivoting moment, the locking lug 26 as well the trigger nose 27 is lifted out of the groove 23.

With the door open (not shown), there is the Latch bolt 10 in that shown in Figures 3 and 4 Trap position in which another extension from Behind the locking lug 26 behind the lock cuff 4th is prevented.

The latch bolt is activated when the door is slammed or closed 10 on the striking plate 33 (Figure 6) in the Additional lock box 3 inserted.

The door is in its closed position and in alignment the latch bolt 10 to the latch opening 32 in the door frame side Strike plate 33 (Figure 6), the fully inserted Latch bolt 10 via the latch extension lever 30 from the Additional lock box 3 pushed out. During this Ejecting movement becomes the blocking element 24 counterclockwise around the collet 25 pivoted. The trigger nose 27 comes with you facing edge of the latch opening 32 of the striking plate 33 in Contact, whereby the locking element 24 against the Swing torque is inserted into the groove 23 so far that the locking lug 26 can slide past the lock cuff 4. In this way, a locking of the latch bolt 10 in the trap position according to Figure 4 prevented, so that the Latchbolt 10 in that shown in Figures 5 and 6 Bolt position can extend. In this latch position the latch bolt 10 about 10 mm to 15 mm further from the Additional lock box 3 extended than in the latch position according to FIGS. 3 and 4.

In a further embodiment, the latch extension lever 30 after pivoting the locking element 24 directly on Latch latch 10 abut and this in the latch position exit.

As can be seen from FIG. 5, the trap tail 34 has one Projection 35 on. It can also be seen from FIG. 5 that around a hinge pin 36 a latch lock lever 37 pivotable is stored and via a locking lever spring 38, which as Leg spring is formed against the direction of the Clockwise is spring loaded. Is the Latch bolt 10 in the fully extended position according to Figures 5 and 6, i.e. in the latch position, then reaches behind a trap locking edge 39 the projection 35. It can between the projection 35 and the trap locking edge 39, as in Figure 5 shown, there is a small distance, however engages the trap locking edge 39 in the displacement path of the Projection 35.

If the latch bolt 10 is now e.g. using a tool or the like inserted into the additional lock box 3 comes the projection 35 on the trap locking edge 39 to the plant and a further insertion is prevented. The latch bolt 10 is in its locked position against insertion locked.

If a trap reset lever 40, the with one arm 41 at the free end of the drive rod 11 and with his other arm 42 on another projection 43 of the Trap tail 34 abuts, pivots, engages a nose 44 the free end of the arm 42 on a backdrop 45 of the Latch lock lever 37 (Figure 5) and lifts it out of his Locking position in which the trap locking edge 39 the Projection 35 engages so far that the Trap locking edge 39 from the displacement path of the projection 35 emerges. In addition, the arm 42 abuts the projection 43 and pulls when pivoting the latch return lever 40 Latch bolt 30 in the additional lock box 3 (FIG. 7). The latch bolt 10 is completely drawn into the box 3 the door can be opened.

With the door open and in the rest position Drive rod 11, the latch bolt 10 on the Trap extension lever 30 extended until the locking lug 26 engages behind the lock cuff 4, as shown in FIG. 4 and prevented another extension.

When inserting the latch bolt 10 by pressing the door shut the case reset lever 40 from this case position in the additional lock box 3 is pivoted, but the arm 41 lifted off the drive rod 11 so that it does not is moved.

Another can be provided via corresponding drivers 46, 46 ' Drive rod 11 'are coupled.

If the bolt is left out of the main lock case 2, you get a lock with a simple panic function because at any time by pressing the button, not shown Lock can be released.
