The Fig. 1 to Fig. 5 show a lock 1 for a door or a window with a movably mounted Wing. The lock 1 comprises a lock mechanism with a pivot bolt 5a, a latch 5b, an auxiliary latch 5c and a lock nut for actuating the pivot bolt 5a. The lock nut 1n includes a first outer nut 1a, a second outer nut 1c, and an inner nut 1b disposed between the first outer nut 1a and the second outer nut 1c. The lock nut cooperates with a coupling device of a first coupling member 3a and a second coupling member 3c. The first outer nut 1a is engageable with the inner nut 1b via the first coupling member 3a, and the second outer nut 1c is engageable with the inner nut 1b via the second coupling member 3c. The first coupling member 3a is pivotally mounted on the side of the inner nut 1b facing the outer nut 1a in a pivot nut bearing on the inner side of the nut. Correspondingly, the second coupling member 3c is pivotally mounted on the side of the inner nut 1b facing the outer nut 1c in a pivot bearing located on the inner side of the nut.

A selection device has an electric motor 2m for actuating the first coupling member 3a and the second coupling member 3c. The engine output acts on the coupling members 3a, 3c via a cam device 2n. Reference is now made to the Fig. 1 and Fig. 4 An output shaft of the electric motor 2m is connected in a torsionally rigid manner to a worm gear 2s formed by a worm and a worm wheel, the worm wheel being connected in a torsionally rigid manner to a cam device 2n.

As in Fig. 5 recognizable, the cam device 2n has a first cam disc, the cam interacts indirectly with the first coupling member 3a, and a second cam, the cam interacts indirectly with the second coupling member 3c. Like from the Fig. 1 . Fig. 4 and Fig. 5 can be seen, the worm wheel is arranged in the illustrated embodiment between the two cams, so that the first cam and the second Cam disc axially spaced from each other are arranged on the cam device 2n. As in particular from the Fig. 1 . Fig. 4 and Fig. 5 As can be seen, the cams of the cam device 2n interact with a first transmission element or transmission element 4a or a second transmission element or transmission element 4c. These transmission elements 4a and 4c are interposed between the cam device 2n and the coupling members 3a, 3c of the nut. The transmission elements 4a and 4c are designed as angle levers, with a first lever arm sliding on the associated cam disk of the cam device 2n and a second lever arm interacting with the associated coupling member 3a or 3c. The transmission elements 4a and 4c are acted upon by a spring device 2f formed by two torsion springs, wherein the leg springs act on the first lever arm of the transmission elements 4a, 4c. The spring device 2f cooperates with the transmission device 4a, 4c in such a way that the transmission device 4a, 4c urges the first coupling element 3a and the second coupling element 3c into engagement (see FIG Fig. 5 ).

It can also be provided that the spring device 2f interacts with the transmission device 4a, 4c such that the transmission device 4a, 4c acts on the first coupling element 3a out of the coupling and / or that the transmission device 4a, 4c removes the second coupling element 3c from the coupling charged out. Thus, the lock according to the invention to different applications, for example, for use on hotel doors or panic doors, adaptable.

The first coupling member 3a and the second coupling member 3c are each formed as a pawl, which - as already mentioned - is pivotally mounted on the inner nut 1b, as best of Fig. 3 can be seen. The coupling members 3a, 3c have a Schaltausnehmung, in which engage the outer nuts 1a, 1c arranged switching lugs. The switching lugs point in each case a switching edge, which engages with the associated coupling member 3 a, 3 c when the associated outer nut 1 a, 1 c is rotated by operating a rotationally rigidly connected to the outer nut 1 a, 1 c handle. The rotational movement introduced at the outer nut 1a, 1c is transmitted via the coupling member 3a, 3c to the inner nut 1b, which actuates the latch 5b and / or the pivot bolt 5a. When the coupling member 3a, 3c is disengaged, the rotational movement introduced at the outer nut 1a, 1c is not transmitted to the inner nut 1b.

The first transmission element 4a and the second transmission element 4c each have a permanent magnet 4m, which is arranged on the coupling member 3a, 3c facing end face (see Fig. 1 ). The first coupling member 3a and the second coupling member 3c are formed of a ferromagnetic or magnetizable material. It can also be provided that the first coupling member 3a and the second coupling member 3c consist only partially of ferromagnetic or magnetizable material. As a result of the magnetic coupling between the transmission element 4a, 4c and the coupling member 3a, 3c, the coupling member 3a, 3c can also be disengaged from the first outer nut 1a or the second outer nut 1c by the transmission element 4a, 4c.

The electric motor 2m described above is connected to a voltage source formed of two primary elements 6p. The primary elements 6p are arranged in a battery compartment 6, which is accessible via a battery compartment cover 6d. The battery compartment cover 6d is arranged in a recess of the forend (see Fig. 2 . Fig. 3 ) and removable after loosening a fixing screw. As in Fig. 3 shown, on the back of the battery compartment cover 6d, an electrical contact plate is arranged, which connects the two primary elements 6p to a battery.

The electric motor 2m can be operated either by a arranged on the door leaf mechanical or electronic switch or by an electronic control device (in the Fig. 1 to Fig. 5 not shown). The lock 1 may have, for example, an antenna for receiving signals and the electronic control device for driving the electric motor 2m as a function of the signals received by the antenna. The lock 1 can be designed as a self-locking lock, which can be unlocked, for example, via an electronic switch designed as a card reader or by means of a remote control cooperating with the aforementioned electronic control device.

The lock has a latch 5a, a spring-mounted, linearly movable latch 5b and an auxiliary latch 5c, designed as a pivot latch in the case shown. An actuating lever 7 is rotatably mounted in the lock housing. He cooperates with the nut 1n and a lock cylinder 8, not shown, and is coupled to the latch 5a.

Depending on the angle of rotation of the cam disc, different configurations of the coupling of the outer nuts to the inner nut can be realized. In the in the Fig. 1 to Fig. 5 the configuration shown is the coupling member 3a in its coupling position and the coupling member 3c in the non-coupling position. This means that the first outer nut 1a is coupled to the lock mechanism; the second outer nut 1c is decoupled from the lock mechanism. In this position of the cam disc 2n, the lock can be unlocked by operating the connected to the first Außenennuss 1a handle. The second outer nut 1c is only rotatable in the freewheel.

Upon rotation of the cam disc 2n by the electric motor 2m by a predetermined angle, for example by 90 ° clockwise, it is achieved that the cam disc 2n pivots the transmission element 4a away from the nut. Because the transmission element 4a interacts with the coupling member 3a via the permanent magnet 4m, the coupling member 3a is also pivoted by the nut into its non-coupling position, so that the outer nut 1a is no longer coupled to the inner nut 1b. In this rotational position of the cam disc 2n is then the first outer nut 1a in the freewheel. The lock 1 is in a safety state and can then be unlocked neither by operating the handle connected to the outer nut 1a nor by actuating the handle connected to the outer nut 1c. However, an unlocking of the lock 1 is always possible, regardless of the rotational position of the cam disc 2n, by lock cylinder actuation.

Depending on the configuration of the cam disc 2n, it is possible to realize up to four different configurations of the coupling of the outer nuts 1a, 1c with the inner nut:

• first outer nut coupled to the inner nut and second outer nut uncoupled from the inner nut; the lock can be unlocked by operating the handle connected to the outer nut;
• first outer nut decoupled from the inner nut and second outer nut coupled to the inner nut; the lock can be unlocked by operating the handle connected to the outer nut;
• first outer nut coupled to the inner nut and second outer nut coupled to the inner nut; the lock can be unlocked both by actuating the handle connected to the outer nut and by actuating the handle connected to the outer nut;
• first outer nut decoupled from the inner nut and second outer nut uncoupled from the inner nut; The lock can not be unlocked either by actuating the handle connected to the outer nut or by actuating the handle connected to the outer nut.

In the illustrated embodiment of the lock 1 is provided that the electric motor 2m is controlled by a remote control. The electric motor 2m then rotates the cam 2n by a rotation angle set in the control of the electric motor 2m, and then transfers the lock 1 from one of the four above-mentioned clutch configurations to another clutch configuration.

In the illustrated embodiment of the lock 1 is in a lock cylinder receptacle 8 (see Fig. 1 ) Can not be used a lock cylinder, not shown. By operating the lock cylinder, the first outer nut 1a and the second outer nut 1c are uncoupled from the inner nut 1b. In this uncoupled state, the first outer nut 1a and the second outer nut 1c are then freewheeled. This means that the lock 1 can not be unlocked either by actuating the handle connected to the first outer nut 1a or by actuating the handle connected to the second outer nut 1c.

It is referred to Fig. 1 and Fig. 4 , The lock 1 has a displaceable by the lock cylinder, not shown actuator 9, which is connected via a transmission device 10 with the transmission elements 4a, 4c. The transmission device 10 comprises in the illustrated case two control cables 10c, 10c ', which are connected via a deflection device 10b. The control cables 10c, 10c 'can also be designed as actuating rods. Upon actuation of the lock cylinder, the actuator 9 is displaced so while a force on the transmission device 10 on the transmission elements 4a, 4c transferred that they are pivoted clockwise against the action of the spring means 2f. Characterized in that the transmission elements 4a, 4c are coupled via the permanent magnets 4m with the coupling members 3a, 3c, the coupling members 3a, 3c are in this case in their non-coupling Positions pivoted. The first outer nut 1a and the second outer nut 1c are decoupled from the inner nut 1b in this position.

One aspect is that this above-described mechanical decoupling of the outer nuts 1a, 1c by actuation of the lock cylinder regardless of the position of the cam device 2n is possible.

Another aspect is that, in the illustrated embodiment, the two handles are actuated by actuation of the lock cylinder, e.g. by means of a key can be switched without effect. This function can also be implemented in a lock that does not provide for patented selection via cams and / or an electric actuator.

In the illustrated embodiment, the lock is designed as a self-locking lock. As soon as the lock reaches its closed position, the bolt 5a automatically moves into its locking position. By actuating the lock cylinder in a first direction of rotation, the lock 1 can be unlocked; by actuation of the lock cylinder in a second direction of rotation, which is opposite to the first direction of rotation, the two outer nuts 1a, 1c of the inner nut 1b are uncoupled.
