Description

The invention relates to a Drückernussanordnung for a castle referred to in the preamble of claim 1. Art and a corresponding lock with such a Drückernussanordnung.

From the DE 10 2015 210 948 A1 For example, a generic lock is known, which comprises a lock housing, a cuff, a bolt, at least one latch, an operable via a door handle pusher and a lock cylinder receptacle. The lock has a modular design and is divided into a closing module comprising the forend, the bolt and the at least one latch, and a drive module comprising the follower and the cylinder lock. In addition, the drive module may comprise a split, electromechanically coupleable follower. With such a fitting or retrofitting of the drive module, it is possible to decouple the pusher of a lock side of the opening mechanism, whereby the access can be controlled in a secure area. This can be done by an access control such as an electronic access control system. In case of authorized access, the two halves of the follower can be electromagnetically triggered and coupled together, so that the lock can also be actuated via the outer handle.

The invention has for its object to provide a Drückernussanordnung and a corresponding lock with such a follower arrangement, which can be easily and quickly adapted by the customer on site to different installation conditions.

This object is solved by the features of the Drückernussanordnung according to claim 1 and by the features of the lock according to claim 19.

Advantageous embodiments and further developments of the invention are specified in the remaining claims.

In order to specify a pusher nut arrangement which can be easily and quickly adapted to different installation conditions by the customer on site, the pusher nut arrangement comprises a second coupling device, which couples a rotatably mounted first component or a rotatably mounted second component of a multi-part follower with an actuating element. In addition, the pusher nut arrangement comprises a first coupling device, which couples the first component and the second component of the pusher nut to one another.

In addition, a lock with a lock housing, a cuff plate, at least one latch, at least one latch and such a presser nut arrangement according to the invention is proposed, which can be actuated via at least one pusher.

Due to the two-part construction of the follower, the first component of the split follower can be coupled with a first pusher and the second component of the split pusher with a second pusher. By means of the first and second coupling devices, embodiments of the presser nut arrangement according to the invention can advantageously be adapted by the customer on site to different installation conditions and safety functions. Thus, the customer can easily switch over the second coupling device a pusher arrangement with a DIN left-engaged pusher in a printer nut arrangement with a DIN right-hook pushers. By software and a corresponding power supply, which is designed for example as a capacitor buffering, can be connected via the first coupling device between a fail-safe operation, i. In the event of a power failure both pushers or components of the pusher nut are coupled in both the direction of escape and in the opposite direction, and a fail-secure operation, i. In case of power failure, only the pusher or the component of the follower in the direction of escape is coupled, be switched.

By these Umstellvarianten created by the same components advantageously high reusability and efficiency. In addition, due to the conversion variants of the locks at the customer fewer wrong deliveries, by incorrect order, rescheduling or incorrect delivery. The second coupling device can be operated, for example, via a drive and an electrical control circuit. Thus, embodiments of the lock according to the invention can be operated independently or integrated into a building control system via a data bus. The drive can be performed, for example, as an electric motor and the first coupling device between a first position in which the two components of the follower are coupled together, and a second position are switched, in which the two components of the follower are decoupled from each other. By the motor control of the second coupling device can also without energization for a long time Lock state are set. For example, you can couple both pushers or components of the follower during the day and couple only the pusher or only the component of the follower in the direction of escape at night and decouple the pusher or the component of the pusher in the opposite direction again. Due to the short engine running time, only little energy is required to switch over in an advantageous manner.

In an advantageous embodiment of the pusher nut arrangement, the first component and the second component of the pusher nut can each be made annular. In this case, the first component comprises at least one first coupling region, and the second component comprises at least one second coupling region. Preferably, the first component and the second component of the follower may each be rotatably supported against the force of a return spring.

In a further advantageous embodiment of the presser nut arrangement, the actuating element may comprise an actuating arm, a rotatably mounted ring and at least one third coupling region, which connects the actuating arm to the ring. The actuating arm of the actuating element can act, for example via suitable transmission elements on at least one latch of the castle. Thereby, the operation of the coupled component of the follower can be transmitted via the corresponding pusher on the bolt. At least the third coupling region of the actuating element can be arranged between the first coupling region of the first component and the second coupling region of the second component of the presser nut. As a result, the second coupling device can be implemented particularly easily. Thus, the second coupling device, for example, a through hole, which penetrates the first coupling region, the second coupling region and the third coupling region, and comprise an axially guided in the passage actuator, which can be moved manually with a predetermined force in the through hole. Therefore, the actuator can be made shorter than the through hole, the actuator in a first axial end position only the first coupling region of the first component of the follower and the third coupling region of the actuating element and in a second axial end position, only the third coupling region of the actuating element and the second coupling region the second component of the pusher nut can penetrate. Preferably, in the first axial end position, the actuating element can abut against a first stop formed in the first coupling region and, in the second axial end position, against a second stop formed in the second coupling region. The actuator can, for example, as a press pin or as a grub screw or as a grooved pin. When executed as a press pin or grooved pin, the customer by simply moving the actuator in the first axial end position or in the second axial end position with a suitable tool, such as a screwdriver, pretend, whether the first component of the follower or the second component of the follower is coupled to the actuating element. In the embodiment as a grub screw, the adjusting element can be moved by screwing with a screwdriver from the first axial end position to the second axial end position or vice versa.

In a further advantageous embodiment of the pusher nut arrangement, the first coupling device may comprise an adjusting device, at least one first recess which is formed on at least one fourth coupling region of the first component, at least one second recess which is aligned with the at least one first recess on at least one fifth coupling region of the second component the pusher nut is formed, and comprise at least one coupling pin, which is guided axially movable in the first recess and / or in the second recess. Here, the at least one coupling pin can be made shorter than an overall length of the first recess and the second recess. In this case, the at least one coupling pin can be arranged completely in the first recess or in the second recess in a first axial end position and be arranged in a second axial end position in the first recess and in the second recess. As a result, the first and second components of the follower are decoupled from each other when the at least one coupling pin is in its first axial end position. Alternatively, the first and second components of the follower are coupled together when the at least one coupling pin is in its second axial end position. The adjusting device may, for example, have a main body designed as a ring segment, which can be connected rotatably with the first component or with the second component of the follower.

In a further advantageous embodiment of the presser nut arrangement, the movement of the at least one coupling pin can take place magnetically. Thus, the at least one coupling pin can be made magnetic. For this purpose, the coupling pin may comprise a magnet or be designed as a magnet. In addition, the adjusting device may have at least two permanent magnets, which can be arranged with different polarity in the main body of the adjusting device. Thus, by adjusting the main body of the adjusting device, the at least one magnetic coupling pin the corresponding recess pulled out or pressed into the corresponding recess. Thus, in a first rotational position of the base body of the adjusting device, a first permanent magnet can be arranged above the corresponding recess and attract the at least one magnetic coupling pin. In a second rotational position of the main body, a second permanent magnet can be arranged over the corresponding recess and repel the at least one magnetic coupling pin. In order to move the main body between the first and second rotational position, the base body can have a toothed segment on some regions, which can mesh a toothing of a drive gear. As a result, the main body of the adjusting device can be moved easily and quickly between the two rotational positions.

In a further advantageous embodiment of the presser nut arrangement, the first component and / or the second component of the follower may have an internal polygon, which can be coupled for actuation with a corresponding first outer polygon of a first pusher or a second pusher. In this case, the polygon socket can be introduced directly into the corresponding component or into an insert, which can be connected in a rotationally fixed manner to the corresponding component. Thus, for example, a first polygon socket can be introduced directly into the first component of the follower, and a second polygon socket can be introduced into an insert which is non-rotatably connected to the second component of the follower. Furthermore, the first polygon socket for operation via a first outer polygon can be coupled to the first pusher, and the second polygon of the insert can be coupled for actuation with a second outer polygon of a second pusher. When assembling the lock, by omitting the insert and a correct positioning of the actuating element, a lock variant can be implemented and constructed with a pusher which can be coupled in on both sides via the first coupling device. In this variant lock the adjusting element of the second coupling device can be adjusted so that the component of the follower is coupled without polygonal socket with the actuating element.

In an advantageous embodiment of the lock, the adjusting element of the second coupling device can be transferred in a DIN-right lock in the first axial end position and a DIN-left lock in the second axial end position.

In a further advantageous embodiment of the lock, an electric motor can act as a drive via a spindle on the drive gear and the main body of the adjusting device move over the sector gear between the first and second rotational position. This allows a cost effective and reliable implementation of the actuator for the actuator.

How out Fig. 1 to 8 it can be seen, a lock 1 according to the invention comprises a support 3 and for a follower arrangement 10, 10A arranged on the support 3. It also includes the lock 1 a lock housing not shown in detail, a not-shown cuff plate, at least one latch, not shown, and at least one not shown case. The Drückernussanordnung 10 can be operated via at least one pusher not shown. Such locks are basically known from the prior art, so that will not be discussed in more detail on the operation. Preferably, the lock 1 according to the invention analogous to that in the DE 10 2015 210 948 A1 disclosed modular lock executed. Embodiments of the lock 1 according to the invention differ from the locks known from the prior art as a result of the presser nut arrangement 10 according to the invention.

How out Fig. 1 to 8 1, the pusher 12 comprises a rotatably mounted first component 12A and a rotatably mounted second component 12B, which via a first coupling device 20 can be coupled together. According to the invention, a second coupling device 30 couples the first component 12A or the second component 12B of the pusher 12 to the actuating element 14.

In Fig. 1 to 4 the two components 12A, 12B of the follower 12 are shown transparent for a better understanding of the invention.

How out Fig. 1 to 8 can be seen, the first component 12A and the second component 12B of the follower 12 are each made annular and each rotatably supported against the force of a return spring 18A, 18B. In addition, the first component 12A in the illustrated embodiment has a first coupling region 12.1A. Analogously, the second component 12B has a second coupling region 12.1B. The actuating element 14 comprises in the illustrated embodiments an actuating arm 14.1, a rotatably mounted ring 14.2 and a third coupling region 14.3, which connects the actuating arm 14.1 with the ring 14.2.

How out fig. 1 to 8 It can also be seen that, in the exemplary embodiments illustrated, at least the third coupling region 14.3 of the actuating element 14 is arranged between the first coupling region 12.1A of the first component 12A and the second coupling region 12.1B of the second component 12B of the presser nut 12. Here, the rotational movements of the annular components 12A, 12B of the follower 12 are guided in the lock housing. The rotational movements of the ring 14.2 of the actuating element 14 are guided by the not coupled to the actuator 14 annular component 12 A, 12 B of the follower 12. For this purpose, the ring 14.2 of the actuating element 14 is inserted in the illustrated embodiments in a corresponding circular recess of the second components 12B and the first component 12 is inserted with a circular collar in the opening of the ring 14.2.

As in particular from FIGS. 5 and 6 it can be seen, the second coupling device 30 comprises a passage opening 32 which penetrates the first coupling region 12.1A, the second coupling region 12.1B and the third coupling region 14.3, and an actuating element 34 guided axially in the passage opening 32, which has a predeterminable force in the passage opening 32 is manually displaceable. Here, the actuator 34 is shorter than the through hole 32 executed. How out FIGS. 5 and 6 It can also be seen that in a first axial end position the adjusting element 34 rests against a first stop 36A formed in the first coupling region 12.1A and in a second axial end position against a second stop 36B formed in the second coupling region 12.1B. In the illustrated embodiments, the actuator 34 is designed as a press pin 34A and can be moved, for example by inserting a screwdriver from the first axial end position to the second axial end position and vice versa. In alternative embodiments, not shown, the actuator 34 may be designed as a grub screw or grooved pin. Of course, other embodiments of the adjusting element 34 are conceivable, which are suitable for coupling the first component 12A or the second component 12B of the follower 112 with the actuating element 34.

Thus, the actuator 34 in a DIN-right lock easily converted easily into the first axial end position and a DIN-left lock in the second axial end position.

How out Fig. 5 It can also be seen that in the illustrated first axial end position, the adjusting element 34 only penetrates the first coupling region 12.1A of the first component 12A of the follower 12 and the third coupling region 14.3 of the operating element 14. As a result, the first component 12A of the follower 12 is coupled to the operating element 14 in that a corresponding actuation of a first pusher, not shown, which is coupled to the first component 12A of the pusher 12, leads to an actuation of the at least one bolt via the actuating element 14 coupled to the first component 12A. The second component 12B of the follower 12 is decoupled in this position of the control element 34 from the control element 14, so that a corresponding actuation of a second pusher, not shown, which is coupled to the second component 12B of the pusher 12, does not lead to any actuation of the at least one bolt.

How out Fig. 6 It can also be seen that in the illustrated second axial end position the adjusting element 34 penetrates only the third coupling region 14.3 of the operating element 14 and the second coupling region 12.1B of the second component 12B of the pusher 12. As a result, the second component 12B of the pusher 12 is coupled to the control element 14 such that a corresponding actuation of a second pusher, not shown, which is coupled to the second component 12B of the pusher 12, leads to an actuation of the at least one bolt via the actuating element 14 coupled to the second component 12B. The first component 12A of the pusher 12 is decoupled from the operating element 14 in this position of the adjusting element 34, so that a corresponding actuation of the first pusher, not shown, which is coupled to the first component 12A of the pusher 12, does not lead to actuation of the at least one bolt ,

How out Fig. 1 to 8 1, the first coupling device 20 in the illustrated embodiments includes an actuator 28, two first recesses 22A formed on two fourth coupling portions 12.2A of the first component 12A, two second recesses 22B in alignment with the two first recesses 22A two fifth coupling regions 12.2B of the second components 12B of the pusher 12 are formed, and two coupling pins 24 which are axially movably guided in the first recesses 22A and / or in the second recesses 22B.

As in particular from FIGS. 7 and 8 it can be seen, the coupling pins 24 are shorter than a total length aligned first recesses 22A and second recesses 22B executed. How out Fig. 7 It can be seen further, the coupling pins 24 are arranged in a first axial end position shown completely in the second recess 22B of the second component 12B of the follower 12, so that the first component 12A and the second component 12B of the follower 12 are decoupled from each other. How out Fig. 8 It can be seen further, the coupling pins 24 are arranged in a second axial end position shown in the first recess 22A of the first component 12A and in the second recess 22B of the second components 12B of the follower 12, so that the first component 12A and the second component 12B of Pusher 12 are coupled together.

How out Fig. 1 to 8 It can also be seen that the adjusting device 28 has a main body 28A designed as a ring segment, which in the exemplary embodiment shown is rotatably connected to the second component 12B of the pusher 12. For this purpose, the ring-segment-shaped main body 28A is guided through an annular collar of the second component 12B of the pusher 12. In the illustrated embodiments, the two coupling pins 24 are each moved by magnetic force. Therefore, the coupling pins 24 are made magnetic. In addition, the adjusting device 28 has four permanent magnets 28.1, 28.2, which are each arranged in pairs with different polarity in the main body 28A. In this case, the two magnet pairs are arranged opposite one another, ie at a distance of approximately 180 °, on the main body 28A. The two individual permanent magnets 28.1, 28.2 of the two pairs of magnets each have a distance of approximately 20 ° to each other in the illustrated embodiment.

How out Fig. 3 and 7 It can also be seen that, in a first rotational position of the main body 28A, a respective first permanent magnet 28.1 is arranged above the corresponding recess 22B and attracts the corresponding magnetic coupling pin 24. This means that the polarization of the first permanent magnets 28.1 is selected so that in the first rotational position unequal poles of the permanent magnets 28.1 and the magnetic coupling pins 24 face each other and tighten.

How out Fig. 4 and 8th It can also be seen that in a second rotational position of the main body 28A a respective second permanent magnet 28.2 is arranged above the corresponding recess 22B and repels the corresponding magnetic coupling pin 24. This means that the polarization of the second permanent magnets 28.1 is selected so that in the second rotational position equal poles of the permanent magnets 28.1 and the magnetic coupling pins 24 face each other and repel each other.

As in particular from FIGS. 7 and 8 as further shown, the first recesses 22A and the second recesses 22B are each configured as blind holes. In this case, floors of the first recesses 22A each form a first stop 26A and bottoms of the second recesses 22B each have a second stop 26B for the coupling pins 24.

In order to move the main body 28A between the first and second rotational position, the main body 28A has, on a peripheral side, a toothed segment 28.3, which meshes with a first toothing 9.1 of a drive gearwheel 9. As in particular from Fig. 2 can be seen, an electric motor acts as a drive 5 via a spindle 7 on a second toothing 9.2 of the drive gear 9 and moves the main body 28A of the adjusting device 28 via the toothed segment 28.3 between the first and second rotational position.

How out Fig. 1 to 8 It can also be seen that the first component 12A has, in all exemplary embodiments, an internal polygon 12.4, which is designed here as a square socket and is introduced directly into the first component 12A of the pusher 12. The inner polygon 12.4 of the first component 12A of the follower 12 can be coupled for actuation with a corresponding outer polygon of the first pusher, not shown.

The second component 12B has an in Fig. 1 to 3 and 5 to 8 illustrated internal embodiment of the Druckernussanordnung 10 a polygonal socket 16.1, which is designed here as a square socket and placed in an insert 16 which is rotatably connected to the second component 12B of the follower 12 is connected. The polygonal socket 16.1 of the insert 16 can be coupled for actuation with a corresponding outer polygon of the second pusher, not shown.

At the in Fig. 1 to 3 and 5 to 8 represented by software and a corresponding power supply or emergency supply via the first coupling device 20 between a fail-safe operation, ie in case of power failure both pushers or components 12A, 12B of the pusher 12 both in the direction of escape and in Counter direction coupled, and a fail-secure operation, ie in case of power failure, only the pusher or the component 12A, 12B of the pusher 12 is coupled in the direction of escape, be switched.

Is the actuator 34 of the second coupling device 30 in the in Fig. 5 shown first axial end position, then the first component 12A of the follower 12 is coupled via the adjusting element 34 with the actuating element 14. As a result, an actuation of the first pusher coupled to the first component 12A of the pusher 12 can be transmitted via the first component 12A and the adjusting element 34 to the actuating element 14 and to the latch operatively connected to the actuating element 14. Are the coupling pins 24 of the first coupling device 20 in the in Fig. 7 illustrated first axial end position, then the first component 12A and the second component 12B of the follower 12 are decoupled from each other, so that an actuation of the coupled with the second component 12B of the follower 12 second pusher causes no actuation of the latch. Are the coupling pins 24 the first coupling device 20 in the in Fig. 8 The first component 12A and the second component 12B of the pusher 12 are coupled together so that actuation of the second pusher coupled to the second component 12B of the pusher 12 via the first coupling device 20 to the first component 12A of the pusher 12 and from there via the adjusting element 34 is transmitted to the actuating element 14 and the bolt. Thus, a panic function can be implemented via the always coupled first pusher and an access authorization query via the coupleable second pusher, so that only authorized users after authorization check and corresponding control signals which act on the drive 5 can unlock the lock 1.

Is the actuator 34 of the second coupling device 30 in the in Fig. 6 shown second axial end position, then the second component 12B of the follower 12 is coupled via the adjusting element 34 with the actuating element 14. As a result, an actuation of the second pusher coupled to the second component 12B of the pusher 12 can be transmitted via the second component 12B and the adjusting element 34 to the actuating element 14 and to the latch operatively connected to the actuating element 14. Are the coupling pins 24 of the first coupling device 20 in the in Fig. 7 illustrated first axial end position, then the first component 12A and the second component 12B of the follower 12 are decoupled from each other, so that an actuation of the coupled with the first component 12A of the follower 12 first pusher causes no actuation of the latch. Are the coupling pins 24 of the first coupling device 20 in the in Fig. 8 illustrated second axial end position, then the first component 12A and the second component 12B of the follower 12 are coupled together, so that an actuation of the coupled with the first component 12A of the follower 12 second pusher on the first coupling device 20 to the second component 12B of the follower 12 and from there via the adjusting element 34 is transmitted to the actuating element 14 and the bolt. Thus, a panic function can be implemented via the always coupled second pusher and an access authorization request via the couplable first pusher, so that only authorized users after authorization check and corresponding control signals acting on the drive 5 can unlock the lock 1.

At an in Fig. 4 illustrated second embodiment of the Druckernussanordnung 10A, the insert 16 is removed with the polygonal socket 16.1 and the second component 12B, the pusher 12 has no internal polygon and therefore can not be operated directly. In addition, the actuator 34 in the in Fig. 6 shown second axial end position, so that the second component 12B of the follower 12 is coupled via the adjusting element 34 with the actuating element 14. In the illustrated second embodiment can be implemented and constructed via the first coupling device 20 a einkoppelbarer pusher. Thus, via the first coupling device 20 and the adjusting device 28, which is controlled via the drive 5, the two components 12A, 12B of the follower 12 are coupled together. The main body 28A of the adjusting device 28 with the permanent magnets 28.1, 28.2 only has to be rotated by approximately 20 °, around the first component 12A of the pusher 12 not connected to the actuating element 14 with the second component 12B connected to the actuating element 14 via the adjusting element 34 the push nut to couple or decouple.
