Abstract

The invention concerns a lock equipped with a bolt mobile between an opening position and a closing position by a control element. Said control element is associated with a lifting magnet. Said magnet locks the control element in closing position with a locking element and moves the locking element to release the closure, from the closing position to the opening position. The invention aims at enhancing the reliability of the closing process of such a lock while enabling a simple construction. Therefor, the lifting magnet is associated with an actuating part, the actuating part comprises a projection which can be actuated by the actuating part and the actuating part releases the lifting magnet from the opening position with the projection.

Description

lock

The invention relates to a lock with a bolt which is adjustable by an actuator between an open and a closed position, the actuator being associated with a lifting magnet, the lifting magnet blocking the actuator in the closed position with a locking piece, and wherein the lifting magnet blocks the locking piece moved to release the lock from the closed and open positions.

Such a lock is known from DE 299 23 398 U 1. The actual locking mechanism is housed in a lock housing. This includes an actuator that is rotatably housed in the lock housing in the form of an actuating nut. The actuator drives as a bolt a movable locking bolt out of the housing and / or a push or espagnolette mechanism. In the closed position, the actuator can by means of a

BESTATIGUNGSKOPIE Solenoids are blocked. This then positively engages the actuator with a locking piece. This prevents the actuator from rotating. The solenoid must be electrically activated to enable the actuator again.

It is an object of the invention to provide a lock of the type mentioned at the outset which works reliably and has a simple structure.

This object is achieved in that an actuating part is assigned to the lifting magnet, that the actuating part has an extension which can be actuated by the actuator, and that the actuating part moves the lifting magnet out of the open position by means of the lever.

In this lock configuration, the actuating part takes over at least part of the lifting magnet adjustment, so that no electrical energy has to be used for this. This then has an especially advantageous effect on battery-powered locks. Because the actuator adjusts the actuating part, a clear and reliable lock actuation is achieved in which the actuating part is forcibly triggered.

According to a preferred embodiment of the invention, it is provided that the lifting magnet has an adjustable armature, which carries the locking piece, and that the armature is held in the closed or open position, pretensioned by means of a spring element. The spring element supports the displacement of the armature into the closed position when the armature is spring-loaded in the open position. is kept biased. This further increases the functional security of the lock. However, if the armature is spring-biased in the closed position, the force that is applied manually via the actuator can be used to tension the spring. This then reduces the energy required to actuate the solenoid.

In addition, it can also be provided that the armature is held in the open position and / or the closed position by means of a permanent magnet assigned to the lifting magnet.

The anchor is then defined in its extreme positions.

According to a conceivable alternative to the invention, it can be provided that the extension of the actuating part runs onto a sliding flank of the actuator during the transition of the actuator from the closed position to the open position, that a lever can be actuated by means of the extension, and that the lever removes the armature of the lifting magnet from the Open position moved out. The lever can be designed in such a way that the offset of the attachment is reduced so that the lifting magnet or its armature is positively adjusted via a desired path. This can then be exploited so that the approach is mechanically controlled via the lever from the open position to the closed position. In particular, it can be provided that the extension is carried by a lever arm, that the lever arm, like the lever, is coupled to a rotary bearing, and that the actuator is rotatably mounted in the lock housing. A lock according to the invention can be characterized in that the actuating part is held in a reset position assigned to the open and closed position of the actuator by means of a return spring, that the actuator, during the transition from the open position to the closed position, on the attachment against the spring force of the return spring adjusts that the actuator releases the actuating part in the closed position for resetting into the reset position. The return spring ensures that the actuating element is always returned to an initial position from which it can be reproducibly adjusted.

To reduce the outlay on parts, it can be provided that the actuating part is designed as a plastic injection-molded part with an integrally formed return spring.

The invention is explained below with reference to an embodiment shown in the drawings. Show it:

1 is a plan view of a lock with a lock housing and a locking mechanism arranged therein,

2 shows the locking mechanism according to FIG. 1 in individual drawing,

Fig. 3 shows the locking mechanism of FIG. 2 in the transition from

Open - in the closed position and Fig. 4 shows the locking mechanism of FIG. 2 in the transition from

Closing and the open position.

1 shows a lock with a lock housing 10. A shoulder housing 1 1 is integrally formed on the side of the lock housing 10. A locking mechanism is accommodated in the lock housing 10 or the attachment housing 11, which can be found in more detail in FIG. 2.

As shown in FIG. 2, the locking mechanism has a bolt 1 2, which can be adjusted back and forth between an open and a closed position by means of an actuator 15. To adjust the bolt 1 2, this is connected in one piece to a locking part 1 3. The closing part 1 3 has a control curve 14. The actuator 1 5 is guided with an eccentric 1 6 in the control curve 14. The eccentric 1 6 is in one piece and rigidly connected to the actuator. The actuator 15 is rotatably supported in the lock housing 10. It can be rotated about an axis of rotation perpendicular to the image axis. As the Fig. 3 reveals, the eccentric 1 6 pushes the closing part when the actuator is rotated from the open to the closed position. In Fig. 1 the fully extended position of the bolt 1 2 and thus the closed position of the lock is shown. In order to return to the open position from this closed position, the actuator 15, as shown in FIG. 4, must be rotated clockwise. The eccentric 1 6 thus slides onto a rear flank 1 5.3 of the control cam 14 and pulls the bolt 1 2 into the housing. In order to be able to secure the lock in the closed position, a lifting magnet 20 is used. This works electrically and is powered by a power source, not shown in the drawings. The power source is preferably a battery, which is accommodated in the lock housing 10. The lifting magnet 20 has an armature 21 which can be adjusted from a closed and an open position by means of the lifting magnet. A locking disk 23 is mounted on the armature. The locking disk 23 supports a spring element 22. On the side facing away from the locking disk 23, the spring element 22 is supported on the housing of the lifting magnet. The armature 21 has a pin 24 which projects in the direction of the actuator 15. As can be seen in FIG. 4, the actuator has a receptacle 15. 1, into which the pin 24 with a locking piece 25 can be inserted. The receptacle 1 5.1 is designed such that the rotation of the actuator 15 is positively hindered when the locking piece is inserted.

An actuating part 30 is arranged on a pivot bearing 33. In the present case, the actuating part 30 is designed as a plastic injection molded part with an integrally formed return spring 34. The return spring is held in a bearing 17 of the lock housing 10. Starting from the pivot bearing 33, the actuating part has a lever 31 projecting in the direction of the lifting magnet 20 and a shoulder 32 guided in the direction of the actuator 15. The return spring 34 holds the operating part 30 in the return position shown in FIG. 1. The functioning of the lock is discussed in more detail below.

Starting from the open position of the lock shown in FIG. 2, the actuator 15 can be rotated counterclockwise. The rotation can take place, for example, by means of a button or a key. During the rotation of the actuator, as clearly shown in FIG. 3, the shoulder 32 of the actuating part 30 slides on a flank 1 5.3 of the actuator 15. As a result, the actuating part 30 is deflected and the lever 31 comes into contact with the locking disk 23 of the armature 21. The armature 21 is held in the open position shown in FIG. 2 on a permanent magnet in the housing of the lifting magnet 20. The lever 31 now releases the armature 21 from the permanent magnet. Thus, supported by the spring element 22, the armature 21 can be advanced in the direction of the actuator 15. With increasing rotation of the actuator 15, the receptacle 5.1 comes into operative connection with the locking piece 25 of the armature 21. The lever 31 is designed such that the armature 21 is forced into the receptacle 14.1. This increases the security of the lock. After the actuator 1 5 is moved into the closed position, the locking piece 25 locks the lock so that it cannot be opened unintentionally. The actuating part 30 snaps into its reset position under the action of the return spring 34. The lock can be opened when an electrical pulse is applied to the solenoid. This electrical pulse can be generated, for example, from an input keyboard. Here a user must enter an approved code. Then a current turns on switched the solenoid, whereby the armature 21 is moved into its open position (see Fig. 2). In the open position, the armature 21 is held on the permanent magnet which is integrated in the lifting magnet 20. The voltage can thus be removed from the lifting magnet 20 and this current can be disconnected.

After the lifting magnet 20 and thus the armature 21 has been moved into the open position, the actuator 15 can be turned back clockwise. The actuating part 30 is deflected passively on a sliding surface 1 5.2 until the shoulder 32 has passed the transition region between the sliding surface 1 5.2 and the flank 1 5.3. Then the actuating part 30 snaps back into its reset position. As a result of the rotation of the actuator 15, the bolt 1 2 can be inserted into the lock housing 1 0. The lock is now available for a new closing process.
