EP2388420A2 - Drive rod operated lock with multiple bolt members - Google Patents

Abstract

The lock has multiple bar units in a main lock part (1), an auxiliary lock part and closing plates that are assigned to the bar units in a frame side, where movement of the bar units to the closing plates takes place by the closing plates. An inference movement of a latch (3) of the main lock part is retarded temporally in relation to the bar units provided in the auxiliary lock part. An actuator (10) is provided at a latch tail (6) of the latch, and cooperates with a bolt arm (12) of a lock bolt (2).

Description

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 gate 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 of the bolt takes place in contrast to the shutter movement synchronously, so that under certain circumstances, large closing forces can occur, especially if the wing is 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 safe on all strike plates, since the drive rod as a rigid drive element in one place, or with a rolling pin already engaged with the strike plate should be in a different location or rolling pin but not yet. Nevertheless, all the trunnions must lock in far enough.

The invention is therefore based on the object to improve a generic lock to the effect that unlocking with lower actuation forces is possible.

To achieve this object, the realization of the features stated in the characterizing part of claim 1 is provided.

The arrangement thus made leads to a simplification of the lock, since the strike plates can be arranged in the known manner and also the bolt of the main lock and the secondary locks can be moved synchronously. Only the case of the main lock remains engaged, so that a possibly occurring sealing pressure does not affect the bars but is first intercepted by the trap. The number of bars to be moved is reduced.

A further embodiment provides that a catch is provided on the latch tail of the case, which cooperates with a nut arm of the lock nut. The trap can be constructed in a conventional manner.

In order to use a same in different embodiments of the castle lock nut, it is provided that the nut arm is assigned to the latch tail via a stationary mounted intermediate arm. The intermediate arm optionally compensates for different dimensions.

In order to use a key-operated lock, a operated via a lock cylinder alternating pressure piece is provided, which acts on a second Nussarm and the drive rod.

In order to achieve the second offset withdrawal of the trap, it is provided that the nut arm is spaced in the pre-closed position of the trap from the driver. This first requires a certain pivot angle of the follower before the nut arm interacts with the trap.

In the in the Fig. 1 main lock 1 shown without lock cover is the locknut with 2 and the latch with 3. While the case head 4 protrudes in the position shown in front of a forend 5, the latch tail 6 is slidably mounted in the housing 7 perpendicular to the forend 5. At the latch tail 6 attacks a leg spring 8 and force the case 4 in the position shown. At an opposite to a cylindrical portion 9 of the latch tail 6 widened executed driver 10, which is also associated with the leg spring 8, is an intermediate arm 11 at.

The lock nut 2 has a first Nussarm 12 and a second Nussarm 13. The first Nussarm 12 lies with its Verschwenkungswinkel in the field of the case 3 and the tailtail 6, while the second Nussarm 13 forms a change arm in the embodiment and is associated with an alternating thrust piece 14 articulated. With an angled end 15 of the nut arm 13 engages a drive rod slide 16.

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, which is received in the cylinder opening 18. The espagnolette 16 is coupled at its upper and lower ends with drive rods 19, 20, which transmit an adjusting movement of the espagnolette 16 to the secondary 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 Fig. 1 shown situation, which results for example in an open wing, the case 3 is advanced by the leg spring 8.

In the Fig. 2 is a position visible in which the case 3 is moved back by a contact with the frame-side strike plate in the housing 7 with simultaneous tension of the leg spring 8. The case 3 is shifted back so far that the driver 10 almost abuts the rear wall of the housing 7. The Nussarm 12 is provided in the direction of the case head 4 with an in the rest position of the lock nut 2 perpendicular edge, so that the Fallenkopfrückseite not to the Nussarm 12th abuts. The espagnolette 16 abuts against the nut arm 13. The insertion of the case 3 leads due to the separation of the Nussarms 12 of the case 3 and the latch tail 6 to no movement of the drive rods 19, 20 or the alternating pressure piece 14. Also, the intermediate arm 11 remains free of movement.

Latches the spring-loaded latch 3 in the strike plate opening, so this occurs again from the housing 7 and before the forend 5 before. It results in the Fig. 1 shown location.

If, starting from this, the main lock is actuated by the cylinder, then the alternating pressure piece 14 is displaced upward in the drawing. As a result of the direct connection to the espagnolette 16 this and the rigidly connected drive rods is immediately entrained and also the lock nut 2 is pivoted by the displacement of the alternating pressure piece 14. Since the Nussarm 12 but in the vorgeschlossenen position ( Fig. 3 ) of the case 3 is spaced from the driver 10, it requires first the bridging of a pivot angle 21 of the lock nut 2, before the Nussarm 12 cooperates with the case 3.

This backlash, which does not lead to any movement of the case 3, has, however, led to a conclusion movement of the directly coupled to the drive rods 19, 20 locking elements. If the alternating pressure piece 14 is displaced further via the key operation, which leads to the lock nut 2 to a pivoting beyond 21 pivoting movement, then the Nussarm 12 acts indirectly via the intermediate arm 11 on the driver 10, and thereby displaced the case. 3

The stationarily mounted intermediate arm 11 forms a transmission member and increases the achievable with the Nussarm 12 way by the Nussarm 12 between the pivot bearing 22 and the contact point 11 'of the intermediate arm 11 and the driver 10 attacks. This facilitates the design with different configurations of the lock with the same lock nut. The intermediate arm 11 optionally 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 FIGS. 5 and 6 show the entire lock 23, which is designed as a multi-point lock in an overview. At the faceplate 5, the main lock 1 and a secondary lock 24 is provided. While at least the latch 3 and a latch 25 are provided in the main lock 1, a pivot bolt 26 and a bolt latch 27 can be brought to preclose via the drive rod 20. These are in a conventional manner in the Nebenschlosskasten 28 stored. The main lock 1 is assigned a cylinder 29 and key 30. Of course, the drive rod 20 can be assigned a further secondary lock.

By the arrangement described in more detail above it is achieved that the pivot bolt 26 and the bolt latch 27 prematurely - namely before the case 3 is withdrawn, be closed back. An optionally existing sealing pressure, which acts on the bolt bolt and / or the pivot bolt and makes it difficult to retract it, is initially taken up by the latch 3. In addition, the number of moving bars is reduced.
