Abstract

Espagnolette lock (23) with a plurality of latch members in a main lock (1) and at least one secondary lock and associated frame-side striking plates, wherein the movement of the locking members (3) to the strike plate is delayed, characterized by a delay over the lock provided in the lock members Inference movement of the trap (3) of the main lock (1).

Description

The The invention relates to a drive rod actuated lock with a plurality of latch members according to the preamble of claim 1. Such a lock is already known.

The DE 4304214 C2 discloses a lock with a main lock and secondary lock, which are interconnected via a drive rod. The main lock has a spring-loaded latch and a lockable latch, while the secondary lock has a lockable bolt latch and a pivoting hook latch. The bolt bolt is moved by a Z-shaped slide attached to a drive rod slider and a link follower engaging therein. It is envisaged that the hook bolt relative to the bolt bolt starts delayed with the shutter movement, so that provided with generous Anzugsschrägen bolt bolt first causes a necessary relative orientation of the wing relative to the frame and thus the hook bolt to the strike plate opening. This achieves a reduced actuating force and a simplified movement control of the bolts. The time delay is essentially achieved by a parallel to the direction of movement of a drive rod slider and a control pin arranged thereon control edge of the pivot bolt protrudes from the one at one end lying eccentrically to the pivot axis cams. Due to this arrangement, the control pin is initially caused to cause an actuation of the drive rod without a pivoting movement of the pivot bolt, while the Z-shaped link is designed so that the Vorschlussbewegung begins after a very small idle stroke to advance the locking pin. The pivoting movement begins by this only when the bolt is already fully advanced.

The opening movement the bolt takes place synchronously, in contrast to the shutter movement, so that under certain circumstances large closing forces occur can, especially if the wing discarded or the seals are still new.

From the DE 3924933 A1 the configuration of a window closure has become known, in which the locking takes place by means of a drive rod displaceable roller journal, which are associated stationary locking plates. In order to keep the required actuating forces as low as possible, the striking plates are arranged so that they are delayed relative to one another or offset from each other in contact with the rolling pins. The disadvantage here is that a particularly large stroke of the drive rod is necessary if the lock is to be made sure of all striking plates, since the drive rod as a rigid drive element in a place or with a rolling pin already in engagement with the strike plate should be another place or rolling pin but not yet. Nevertheless, all the trunnions must lock in far enough.

Of the Invention is therefore based on the object, a generic Lock to improve that unlocking with lower actuation forces is possible.

to Solution to this problem is the realization of the characterizing Part of claim 1 features provided.

The Such a configuration leads to a simplification of the lock, since the strike plates in the well-known Art and can be arranged and also the bars the main castle and the auxiliary locks moved synchronously can be. Only the trap of the main castle remains in the Intervention, so that a possibly occurring sealing pressure does not occur The bars influence but first of the trap is intercepted. The number of bars to be moved is here reduced.

A Continuation provides that at the trap tail of the trap Driver is provided with a nut arm of the lock nut interacts. The trap can be constructed in the usual way become.

Around a same in different embodiments of the castle To be able to use castle nut, it is provided that the Nut arm the trap tail over a stationary stored Assigned to intermediate arm. The intermediate arm is equal if necessary different dimensions.

Around to use a lock also key-operated, is an operable via a lock cylinder Alternating pressure piece provided, which on a second Nussarm and the drive rod acts.

Around To achieve the second-delayed retreat of the trap is provided that the nut arm in the pre-closed position of the Trap spaced from the driver. This requires it first a certain swing angle of the printer's nut before the nut arm interacts with the trap.

Further advantageous embodiments will become apparent from the drawings. It shows:

1 a main lock case of a drive rod lock without lock cover in open position,

2 the castle after 1 with retarded trap,

3 the castle after 1 at the beginning of a change operation and

4 the castle after 1 with trapped trap

5 a multiple lock with a main and a secondary lock in a side view and

6 a multiple lock in a frontal view.

In the in the 1 main lock without lock cover 1 is the castle nut with 2 and the trap with 3 designated. While the case head 4 in the position shown in front of a forend 5 protrudes, is the trap tail 6 in the case 7 perpendicular to the forend 5 slidably mounted. At the trap tail 6 grips a thigh spring 8th on and force the trap 4 in the position shown. At one opposite to a cylindrical section 9 of the tail-tail 6 widened executed driver 10 , which is also the leg spring 8th is assigned, lies an intermediate arm 11 at.

The castle nut 2 has a first nut arm 12 and a second nut arm 13 on. The first nut arm 12 lies with its Verschwenkungswinkel in the field of the trap 3 or the tail-tail 6 while the second nut arm 13 forms a change arm in the embodiment and a change pressure piece 14 articulated is assigned. With an angled end 15 grabs the nut arm 13 on a drive rod slider 16 at.

The end 17 of the alternating pressure piece 14 is in a conventional manner in the pivoting range of a driver of a profile cylinder, not shown here, in the cylinder opening 18 is included. The espagnolette 16 is at its upper and lower end with espagnolettes 19 . 20 coupled, which is an actuating movement of the espagnolette 16 transferred to the auxiliary locks, not shown here.

The mode of operation of the castle thus constructed will now be illustrated by means of various switching positions. In the in 1 shown situation, which results for example in an open wing, is the case 3 through the thigh spring 8th advanced.

In the 2 is a position visible where the trap 3 by a contact with the frame-side strike plate in the housing 7 with simultaneous tension of the leg spring 8th is relocated. The trap 3 is shifted back so far that the driver 10 almost to the back wall of the housing 7 abuts. The nut arm 12 is in the direction of the case head 4 with a resting position of the castle nut 2 provided perpendicular edge, so that the case back is not on the Nussarm 12 abuts. The espagnolette 16 is located on the nut arm 13 at. The insertion of the trap 3 results from the separation of the nut arm 12 from the trap 3 or the tail-tail 6 to no movement of the drive rods 19 . 20 or the alternating pressure piece 14 , Also the intermediate arm 11 remains motion-free.

Latches the spring-loaded latch 3 in the strike plate opening, so this comes out of the housing again 7 and in front of the forend 5 in front. It results in the 1 shown location.

If, starting from this, the main lock is actuated by the cylinder, then the alternating pressure piece becomes 14 shifted upward in the drawing. Due to the direct connection to the espagnolette 16 this and the rigidly connected drive rods are immediately carried along and also the lock nut 2 is due to the displacement of the alternating pressure piece 14 pivoted. Because the nut arm 12 but in the preconnected position ( 3 ) of the trap 3 from the driver 10 spaced apart, it requires first the bridging of a swivel angle 21 the castle nut 2 before the nut arm 12 with the trap 3 interacts.

This backlash, which does not cause any movement of the trap 3 leads, however, has a conclusion movement of directly with the drive rods 19 . 20 guided coupled locking elements. Is via the key operation the alternating pressure piece 14 relocated what was on the lock nut 2 to one over the swivel angle 21 outgoing pivotal movement leads, then acts the Nussarm 12 indirectly via the intermediate arm 11 on the driver 10 , thereby shifting the trap 3 ,

The fixedly mounted intermediate arm 11 forms a translation link and enlarges it with the nut arm 12 achievable way by the nut arm 12 between the pivot bearings 22 and the contact point 11 ' of the intermediate arm 11 and the driver 10 attacks. This facilitates the design in different embodiments of the castle with the same locknut The intermediate arm 11 If necessary, compensates for the different dimensions. For this purpose, in some cases another arrangement of the pivot bearing 22 , In addition, it is achieved that the now available to a small extent pivot angle of the lock nut leads to a complete retraction of the case.

The 5 and 6 show the entire castle 23 , which is designed as a multi-point lock in an overview. At the forend 5 is the main castle 1 and a minor lock 24 intended. While in the main castle 1 at least the trap 3 and a latch 25 are provided, via the drive rod 20 a pivot bolt 26 and a bolt latch 27 to be brought to a conclusion. These are in a conventional manner in the secondary lock box 28 stored. The main castle 1 is a cylinder 29 and keys 30 assigned. Of course, the drive rod 20 another secondary lock can be assigned.

By the arrangement described in more detail above is achieved that the pivot bolt 26 and the bolt bolt 27 prematurely - namely before the trap 3 is withdrawn, be closed back. Any existing sealing pressure, which acts on the bolt latch and or the pivot bolt and the withdrawal of the same difficult, is first of the case 3 added. In addition, the number of moving bars is reduced.
