Description

The present invention relates to an actuating device with a housing and with an actuating element, wherein the actuating element is adjustable relative to the housing between a first actuating element position and a further actuating element position, wherein a locking mechanism is provided for securing the actuating element against unauthorized adjustment from the first actuating element position to the further actuating element position, wherein the locking mechanism comprises at least one locking element which is adjustable between a locking position for positively blocking the adjustment of the actuating element from the first actuating element position to the further actuating element position and an unlocking position for enabling the adjustment of the actuating element from the first actuating element position to the further actuating element position, and wherein the locking element has at least one locking magnet for adjusting the locking element from the locking position to the unlocking position by the magnetic interaction between the locking magnet and at least one unlocking magnet of a corresponding key unit. The present invention further relates to a system with such an actuating device and a corresponding key unit.

An actuating device in the form of a pivoting lever for actuating a locking device is known from WO 2021/190908 A1 Such a pivoting lever allows easy handling and quite secure access control with a mechanically simple and quite robust design.

However, depending on the environmental conditions or the use of force due to vandalism, such an actuating device may cause the locking mechanism to become blocked.

Against this background, the object of the present invention is to provide an improved actuating device which enables more reliable locking and unlocking.

The above-mentioned object is achieved according to the invention by an actuating device with a housing and with an actuating element, wherein the actuating element is adjustable relative to the housing between a first actuating element position and a further actuating element position, wherein a locking mechanism is provided for securing the actuating element against unauthorized adjustment from the first actuating element position to the further actuating element position, wherein the locking mechanism comprises at least one locking element which is adjustable between a locking position for positively blocking the adjustment of the actuating element from the first actuating element position to the further actuating element position and an unlocking position for enabling the adjustment of the actuating element from the first actuating element position to the further actuating element position, and wherein the locking element has at least one locking magnet for adjusting the locking element from the locking position to the unlocking position by the magnetic interaction between the locking magnet and at least one Unlocking magnets of a corresponding key unit, wherein the locking element comprises a pivot arm which is pivotably mounted about a locking element axis and which can be pivoted from the locking position into the unlocking position, and that the locking magnet is arranged on the pivot arm at a distance from the locking element axis.

The locking element comprises a pivotably mounted pivot arm on which the locking magnet is arranged. The locking element is thus formed in particular by the pivot arm and the locking magnet arranged thereon, so that a pivotable locking element with a locking magnet is provided. It is also conceivable for the locking element to comprise several locking magnets.

By providing a pivot arm that is pivotally mounted about a locking element axis and can be pivoted from the locking position to the unlocking position, a locking element is provided that is reliably guided between the locking position and the unlocking position, so that tilting of the locking element can be reliably prevented, even in the event of adverse environmental influences or the use of force due to vandalism.

The locking magnet is arranged at a distance from the locking element axis on the swivel arm. In particular, the center of the locking magnet or the center axis of the locking magnet running through the north and south poles of the locking magnet is arranged at a distance from the locking element axis.

The locking magnet arranged at a distance from the locking element axis on the swivel arm can create a lever effect on the swivel arm through magnetic interaction with the locking magnet in order to pivot it specifically between the locking position and the unlocking position.

The locking magnet is preferably arranged at a distance from the locking element axis such that the locking magnet is arranged completely outside the locking element axis. In this way, a longer lever arm is achieved. However, it is also conceivable for the locking element axis to run through a lateral region of the locking magnet, as long as the center point or the central axis of the locking magnet is spaced from the locking element axis.

The swivel arm is preferably made of a non-ferromagnetic material, in particular aluminum or plastic, in order to weaken the magnetic interaction of the locking magnet with an unlocking magnet of a corresponding key unit as little as possible or not at all.

The above-mentioned object is further achieved according to the invention by a system with the previously described actuating device or an embodiment thereof and with a corresponding key unit, wherein the corresponding key unit has at least one unlocking magnet corresponding to the at least one locking magnet of the actuating device.

The key unit is preferably designed to pivot the at least one locking element into the unlocking position by magnetic interaction between the at least one unlocking magnet and the at least one locking magnet when the key unit is in contact with a key contact surface of the actuating device.

The actuating device described above and the system described above or a respective embodiment thereof are preferably each designed as part of an access control device, for example on a flap or door, in particular a thin door such as a sheet metal door, and/or are used for this purpose.

Various embodiments of the actuating device and the system are described below, whereby the individual embodiments apply independently of one another to the actuating device and the system. In addition, the individual embodiments can be combined with one another as desired.

In one embodiment, the swivel arm has a blocking section which, in the locking position, positively blocks the adjustment of the actuating element from the first actuating element position to the further actuating element position and releases it in the unlocking position. The blocking section can, for example, engage in a receptacle provided for this purpose in the housing in the locking position in order to block the adjustment of the actuating element to the further actuating element position.

The blocking section can be arranged on the same side of the swivel arm as the locking magnet in relation to the adjustment element axis. It is also conceivable that the blocking section and the locking element are arranged on different sides of the swivel arm in relation to the adjustment element axis. In this way, the blocking section can be arranged further away from the locking magnet, which enables a more robust design of the blocking section.

In one embodiment, the swivel arm has a stop surface which strikes a counter surface when the swivel arm is swiveled when the locking position or the unlocking position is reached. In this way, the locking position or the unlocking position can be set as defined end positions of the swivel arm. In this way, a more reliable and more uniform movement of the swivel arm can be achieved. The counter surface can be formed, for example, by the housing or the actuating element.

The swivel arm preferably has a first stop surface which strikes a first counter surface when the swivel arm is swiveled when the locking position is reached, and a second stop surface which strikes a second counter surface when the swivel arm is swiveled when the unlocking position is reached. The first counter surface can be formed, for example, by the housing and the second counter surface by the actuating element, or vice versa.

In one embodiment, the locking mechanism comprises at least two locking elements, each with a pivotably mounted pivot arm and a locking magnet arranged thereon. In this way, security can be ensured against unauthorized adjustment of the actuating element from the first actuating element position to the further actuating element position. position. This is all the more true if the locking mechanism comprises at least four, preferably at least six, in particular at least eight, locking elements, each with a pivotably mounted pivot arm and locking magnets arranged thereon. Regardless of the number of locking elements, it is expedient if the locking elements can each be adjusted between a locking position and an unlocking position. Alternatively or additionally, it may be advisable for the locking mechanism to function simply if the locking elements each comprise at least one locking magnet.

In one embodiment, the pole orientations of at least two of the locking magnets of different locking elements differ in relation to the direction from the locking position to the unlocking position of the respective locking element. In this way, security against unauthorized adjustment of the actuating element is further increased. In particular, coding can be implemented in this way so that it is more difficult for unauthorized persons to adjust all locking elements to the respective unlocking position. Preferably, the pole orientations of at least two adjacently arranged locking magnets can differ.

In one embodiment, the pivoting directions from the locking position to the unlocking position of the respective locking element of at least two different locking elements differ.

In some structural designs, more locking elements can be accommodated in a given installation space. Furthermore, the vibration resistance of the locking mechanism can be improved in this way.

In one embodiment, the actuating device is an actuating device for actuating a locking device, the actuating element is an actuating element for actuating the locking device, the first actuating element position is a locking position and the further actuating element position is an actuating position for actuating the locking device. The actuating device can in particular be a pivoting lever device.

Accordingly, the above-mentioned object is achieved in particular by an actuating device, in particular a pivot lever device, for actuating a locking device with a housing and with an actuating element for actuating the locking device, wherein the actuating element is adjustable relative to the housing between a locking position and an actuating position for actuating the locking device, wherein a locking mechanism is provided for securing the actuating element against unauthorized adjustment from the locking position to the actuating position, wherein the locking mechanism comprises at least one locking element which is adjustable between a locking position for positively blocking the adjustment of the actuating element from the locking position to the actuating position and an unlocking position for releasing the adjustment of the actuating element from the locking position to the actuating position, wherein the locking element has at least one locking magnet for adjusting the locking element from the locking position to the unlocking position by the magnetic interaction between the locking magnet and at least one unlocking magnet a corresponding key unit, and wherein the locking element comprises a pivot arm which is pivotably mounted about a locking element axis and which can be pivoted from the locking position into the unlocking position, and wherein the locking magnet is arranged on the pivot arm at a distance from the locking element axis.

It has been shown that the described locking mechanism with the one or more locking elements having a respective pivot arm is particularly advantageous for providing an actuating element that can be reliably locked and unlocked in a locking position. In particular, the actuating device can be made of WO 2021/190908 A1 be improved.

In one embodiment, the actuating element is designed as a pivot lever, wherein the pivot lever can be pivoted about an actuating axis of rotation relative to the housing in the actuating position. The pivot lever is preferably connected to a rotatable actuating shaft, which can be driven by pivoting the pivot lever about the actuating axis of rotation, for example in order to actuate a locking device connected to the actuating shaft, such as a single- or multi-point locking device.

In one embodiment, the housing has a recess in which the actuating element is accommodated in the locking position. In this way, the actuating element can be use, thereby achieving a flatter design and reducing the risk of accidentally getting caught on the actuating element or the risk of vandalism. For this purpose, the actuating element can be adjusted from the first actuating element position to the further actuating element position and/or vice versa, in particular by folding around a folding axis.

In one embodiment, the housing has a housing plane in which the recess is embedded, and the actuating element has a flat upper side which, when the actuating element is accommodated in the recess, is essentially parallel, preferably flat, to the housing plane. The upper side of the actuating element preferably has an angle of less than 5°, preferably less than 2°, to the housing plane. Additionally or alternatively, the upper side of the actuating element preferably protrudes less than 10 mm, preferably less than 5 mm, above the housing plane. In this way, a particularly flat design is possible.

In one embodiment, the housing has a locking part and the actuating element has a locking part receptacle corresponding to the locking part, in the locking position of the actuating element the locking part is received in the locking part receptacle and the locking element engages in a recess in the locking part in the locking position. In this way, the positive locking is achieved by the one or more locking elements below the actuating element, which makes manipulation of the actuating device more difficult.

In one embodiment, corresponding contours, in particular sliding surfaces, are provided on the swivel arm and on the housing, in particular on the locking part, which interact with one another when the actuating element is adjusted from the further actuating element position, in particular actuating position, to the first actuating element position, in particular locking position, in such a way that the swivel arm enables the actuating element to be adjusted to the first actuating element position, in particular is swiveled in the direction of the unlocking position. In this way, the actuating element can be adjusted to the first actuating element position, in particular locking position, when the key unit is removed, without the swivel arm blocking this adjustment. In a swivel lever device, for example, the swivel lever can be folded into a recess in the housing even without the key unit.

As mutually corresponding contours, for example, mutually corresponding inclined sliding surfaces or an inclined sliding surface and a corresponding edge can be provided on the swivel arm and on the housing, in particular on the locking part, which slide against each other when the actuating element is adjusted to the first actuating element position and, for example, cause the swivel arm to pivot in the direction of the unlocking position.

In one embodiment, the actuating element has a key support contour that is freely accessible in the locking position, and the at least one locking magnet is arranged for adjusting the locking element from the locking position to the unlocking position when a corresponding key unit is placed on the key support contour. In this way, manipulation of the actuating device with a geometrically unsuitable key unit is made more difficult. In addition, the key support contour makes it easier for a user to correctly position the key unit and thus operate the actuating device. The key contour preferably has such an asymmetry that the corresponding key unit can only be placed on the key support contour in one orientation.

In one embodiment, the locking mechanism comprises at least two, if necessary at least four, preferably at least six, in particular at least eight, locking elements, and at least two of the locking elements are arranged on opposite sides of a longitudinal axis of the actuating element and/or a longitudinal axis of the housing. In this way, the security against forcible adjustment of the actuating element from the locking position to the actuating position can be increased. This applies even more if at least two locking element groups, each comprising at least two, in particular at least three, locking elements are arranged on opposite sides of the longitudinal axis of the actuating element and/or the longitudinal axis of the housing.

In one embodiment, the locking mechanism comprises at least two, if necessary at least four, preferably at least six, in particular at least eight, locking elements, and at least two of the locking elements are arranged spaced apart from one another along the longitudinal axis of the actuating element and/or along the longitudinal axis of the housing. In this way, the actuating element can be positively locked at different points along its longitudinal axis in the locking position. held on the housing. This can also increase the security against forcible adjustment of the actuating element from the locking position to the actuating position. This applies in particular if at least two locking elements of a locking element group are arranged at a distance from one another along the longitudinal axis of the actuating element and/or the longitudinal axis of the housing.

Preferably, the distances between adjacent locking elements along the longitudinal axis of the actuating element and/or the housing are the same. This facilitates the manufacture of the actuating device or the key unit.

In one embodiment, in the locking position of the actuating element, the locking element is accommodated in the locking position and/or unlocking position in the housing and/or the actuating element in such a way that the locking element is inaccessible from the outside. In this way, the security against damage to the locking mechanism from the outside can be further increased.

Alternatively or additionally, it can be provided that the at least one locking element is accommodated in the locking position and/or the unlocking position in the housing and/or the actuating element in such a way that the locking element is not visible from the outside when the actuating element is in the locking position. In this way, the security against unauthorized adjustment of the locking element from the locking position to the unlocking position can be increased.

Irrespective of this, it may be expedient if, in the locking position of the actuating element, the locking element is accommodated partly in the housing in the locking position and partly in the actuating element and/or in the unlocking position in the housing or the actuating element.

In one embodiment, the locking element is accommodated in an unlocking receptacle of the actuating element or the housing in the unlocking position, preferably independently of the position of the actuating element. In this way, damage to the locking element can be easily prevented when the locking element is in the unlocking position.

In one embodiment, the locking element engages in a locking receptacle of the housing or the actuating element in the locking position of the actuating element in a form-fitting manner. In this way, the adjustment of the actuating element from the locking position to the actuating position can be blocked in a form-fitting manner in a structurally simple manner.

In one embodiment, the locking mechanism comprises at least one securing element for automatically adjusting the at least one locking element from the unlocking position to the locking position when adjusting the actuating element to the locking position. In this way, it can be avoided that the at least one locking element inadvertently remains in the unlocking position when adjusting the actuating element from the further actuating element position, in particular actuating position, to the first actuating element position, in particular locking position.

The at least one securing element can be designed to automatically adjust the at least one locking element from the unlocking position to the locking position when the actuating element is adjusted to the first actuating element position, in particular locking position. In this way, the locking element can be automatically adjusted from the unlocking position to the locking position by the securing element when the actuating element is adjusted to the first actuating element position, in particular locking position. This can increase security against unauthorized adjustment of the actuating element from the first actuating element position, in particular locking position, to the further actuating element position, in particular actuating position.

Alternatively or additionally, the at least one securing element can also be designed to hold the at least one locking element in the locking position when the actuating element is in the first actuating element position, in particular the locking position. This can also contribute to increased security against unauthorized adjustment of the actuating element from the first actuating element position, in particular the locking position, to the further actuating element position, in particular the actuating position.

Irrespective of this, in the case of a plurality of locking elements, it may be advisable for the sake of simplicity if the at least one securing element is assigned to several locking elements. In this way, a separate securing element does not have to be provided for each locking element.

The security element can be attached to the actuating element. For a simple functioning of the locking mechanism, the at least one security element is preferably attached to the housing. Alternatively or additionally, the at least one security element can be at least partially, in particular at least substantially, accommodated in the housing or the actuating element. In this way, it can be ensured that the security element is inaccessible from the outside, which can increase security against damage to the locking mechanism due to vandalism and unauthorized adjustment of the locking element from the locking position to the unlocking position.

In one embodiment, the at least one securing element is made of a ferromagnetic material and the locking element is preferably automatically adjustable from the unlocking position to the locking position due to the magnetic interaction between the locking magnet and the securing element when the actuating element is adjusted to the first actuating element position, in particular the locking position. This not only enables a particularly simple structural design, but also a reliable functioning of the locking mechanism.

For the same reason, it may alternatively or additionally be advantageous if, in the first actuating element position, in particular the locking position, of the actuating element, the at least one locking element is held in the locking position by the magnetic interaction between the at least one locking magnet and the at least one securing element.

In principle, the automatic adjustment of the locking element and/or the holding of the locking element in the locking position can be carried out at least partially by the magnetic interaction between the locking magnet and the securing element. For the reasons mentioned above, however, it is particularly preferred if the automatic adjustment of the locking element and/or the holding of the locking element in the locking position is carried out at least substantially by the magnetic interaction between the locking magnet and the securing element.

In this case, a ferromagnetic material is understood to mean a material that is attracted to an external magnetic field. The security element can therefore in principle also be designed as a permanent magnet. However, in order to ensure that the locking mechanism functions simply and reliably, it is preferred if the security element itself does not generate a magnetic field.

In one embodiment, the actuating device is a closure, in particular a rotary latch closure such as a cam lock, the actuating element is a locking core rotatably mounted in the housing, the locking core is designed at a first end accessible from a front side of the closure for the torque-transmitting attachment of the corresponding key unit, the first actuating element position is a first rotational position of the locking core in the housing, in particular an open position or a closed position, and the further actuating element position is a second rotational position of the locking core in the housing, in particular a closed position or an open position.

The above-mentioned object is therefore also achieved in particular by a closure, in particular a rotary latch closure such as a cam lock, with a closure housing and with a locking core rotatably mounted in the closure housing, wherein the locking core is designed at a first end accessible from a front side of the closure for the torque-transmitting insertion of a key, wherein a locking mechanism is provided for securing the locking core against unauthorized rotation of the locking core between an open position and a closed position, wherein the locking mechanism comprises at least one locking element which is adjustable between a locking position for positively blocking a rotation of the locking core in the closure housing between the open position and the closed position and an unlocking position for releasing the rotation of the locking core between the open position and the closed position, wherein the locking element has at least one locking magnet for adjusting the locking element from the locking position to the unlocking position by the magnetic interaction between the locking magnet and at least one unlocking magnet of a corresponding key, and wherein the locking element comprises a pivot arm which is pivotably mounted about a locking element axis and which can be pivoted from the locking position into the unlocking position, and that the locking magnet is arranged on the pivot arm at a distance from the locking element axis.

It has been shown that the described locking mechanism with the one or more locking elements having a respective pivot arm is also particularly advantageous for providing a rotary latch with a reliably lockable and unlockable locking core rotation.

In one embodiment, the locking mechanism comprises at least two, preferably at least three locking elements, each with a pivotably mounted pivot arm and a locking magnet arranged thereon, and the locking elements are preferably arranged around the axis of rotation of the locking core. In this way, the security against manipulation of the rotary latch is increased. In addition, this enables a higher number of pivot arms with locking magnets, which in combination allow a larger number of different rotary latch-key unit pairs.

In one embodiment, the locking core has a contour part at the first end, which has a circumferential contour delimiting the contour part in the circumferential direction for the torque-transmitted attachment of the corresponding key unit and is preferably flat between the circumferential contour. In this way, a particularly flat design is achieved, which in particular increases the robustness against vandalism.

In one embodiment, a security element is provided which is designed to hold the at least one locking element in the closed position when the key unit is removed by magnetic interaction, in particular between the security element and the locking element. In this way, the vibration resistance of the lock is increased, so that even in the event of mechanical vibrations or shaking, the locking elements are held securely in the closed position when the key is removed, thus preventing the lock from opening or closing when the key is removed. In the case of several locking elements, the security element can preferably be designed to hold the several locking elements in the closed position when the key is removed by magnetic interaction between the security element and the locking element.

The magnetic interaction between the securing element and the blocking element or the multiple blocking elements is preferably a magnetically attractive interaction. However, it is also conceivable that the magnetic interaction between the securing element and the blocking element or the multiple blocking elements is a magnetically repulsive interaction.

For example, the blocking element can be a magnet or comprise a magnet and the securing element can also be a magnet or consist of a ferromagnetic material, for example as a ferromagnetic metal plate or metal ring, for example a steel plate or steel ring.

Further features and advantages of the actuating device and the systems will become apparent from the following description of embodiments, with reference to the accompanying drawings.

In the drawing show

• 1a -f a first embodiment of the actuating device in the form of a pivoting lever device with the pivoting lever in the locking position and the locking elements in the locking position as well as a first embodiment of the system,
• 2a -c the embodiment from 1a -e with the pivot lever in the actuating position and the locking elements in the unlocking position,

• 4a -f a second embodiment of the actuating device in the form of a rotary lock with the locking elements in the locking position and a second embodiment of the system,
• 5a -c the embodiment from 4a -f with the locking elements in the unlocking position,
• 6a -c a third embodiment of the actuating device in the form of a rotary lock with the locking elements in the locking position and a second embodiment of the system and
• 7a -c the embodiment from 6a -c with the locking elements in the unlocked position.

The 1a -e show a first embodiment of the actuating device in the form of a pivoting lever device and a first embodiment of the system in different views. 1a shows a perspective view of the pivot lever device 2 and the key unit 4, which together form the system 6. 1b show a top view. 1c shows a sectional view corresponding to the 1b cutting plane designated “Ic”. 1d shows a view of the key unit 4 from below, with some hidden elements shown with dashed lines. 1e shows a sectional view corresponding to the 1c cutting plane designated “Ie”. 1f shows a locking element in perspective view.

The pivot lever device 2 has a housing 10 and an actuating element 12 in the form of a pivot lever.

The pivot lever 12 is pivotable relative to the housing 10 about a pivot lever folding axis 17 between a locking position ( 1a -e) and an actuation position ( 2a -c) adjustable.

2a -c show the system 6 with the pivot lever device 2 and the key unit 4 with the pivot lever 12 in the actuating position. 2a shows a perspective view, 2b shows a sectional view with a 1c corresponding cutting plane. 2c shows a sectional view corresponding to the 2b cutting plane designated “IIc”.

In the actuating position, the pivot lever 12 can be pivoted about an actuating axis of rotation 13, whereby the pivot lever 12 transmits a rotary movement to an actuating shaft 16, via which the pivot lever 12 is connected or can be connected to a locking device 14, for example a single or multi-point locking device of an access device such as a door or flap. In this way, the locking device 14 can be actuated by pivoting the pivot lever 12 about the actuating axis 13. A pivoted position of the pivot lever 12 is shown by way of example 3 in perspective view (operated position).

In the locking position ( 1a -e) the pivot lever 12 is accommodated in a recess 18 of the housing 10. In this way, accidental actuation of the pivot lever 12 can be prevented. In addition, this enables a flat design, which can prevent, for example, accidental snagging on a protruding pivot lever 12.

The flat design of the pivot lever device 2 is achieved in particular in that the pivot lever 12 has a flat upper side 20 which, when the pivot lever 12 is received in the recess 18, is parallel to the housing plane 21.

The pivot lever 12 is further protected against unauthorized adjustment from the locking position ( 1a -e) secured in the actuating position (2a-c). For this purpose, the pivot lever device 2 has a locking mechanism 22 which prevents the pivot lever device 2 from being moved from the locking position to the actuating position without the key unit 4.

The locking mechanism 22 comprises a plurality of locking elements 24, in the present embodiment eight locking elements, each of which can be moved between a locking position ( 1e) , in which the locking elements 24 positively block the adjustment of the pivot lever 12 from the locking position to the actuating position, and an unlocking position ( 2c ), in which the locking elements 24 enable the pivot lever 12 to be moved from the locking position to the actuating position.

For this purpose, the individual locking elements 24 each have a pivot arm 28 mounted about a locking element axis 26, which can be pivoted from the locking position to the unlocking position. In the present embodiment, the pivot arms 28 have lateral bearing shafts 30 for this purpose, with which they are mounted in corresponding bearing receptacles 32 in the pivot lever 12.

Furthermore, the pivot arms 28 have blocking sections 34 which, in the locking position of the respective pivot arm 28, engage in a locking receptacle 36 of the housing 10, which in the present embodiment is formed by two opposite recesses 38 of a locking part 40 protruding in the recess 18.

Furthermore, the pivot arms 28 each have a first stop surface 42 and a second stop surface 44, wherein the first stop surface 42 strikes a counter surface 46 of the pivot lever 12 when the locking position is reached, thereby defining the locking position, and wherein the second stop surface 44 strikes a counter surface 48 of the pivot lever 12 when the unlocking position is reached, thereby defining the unlocking position. The pivoting movement of the individual pivot arms 28 is limited by the stop surfaces 42, 44 and the corresponding counter surfaces 46, 48, thereby ensuring a reliable and repeatable change between the locking and unlocking positions. In the present example, the first and second counter surfaces 46, 48 are identical. However, the first and second counter surfaces can also be different surfaces.

A respective locking magnet 50 is also arranged on the pivot arm 28 of the individual locking elements 24, specifically at a distance from the respective locking element axis 26, so that a magnetic force acting on the locking magnet 50 can cause the pivot arm 28 to pivot between the locking and unlocking positions via the lever between the position of the locking magnet 50 and the locking element axis 26.

The locking magnets 50 are arranged on the pivot arms 28 in respective locking magnet receptacles 51 of the pivot arms 28.

The pivot lever device 2 has a securing element 52 which basically holds the pivot arms 28 in the locking position ( 1e) In the present embodiment, the securing element 52 is designed in the form of a steel element arranged in the locking part 40. A magnetic attraction force acts between the locking magnets 50 and the steel element 52, which basically holds the pivot arms 28 in the locking position (holding force).

The pivot lever 12 has a locking part receptacle 54 on its underside, which is adapted to the locking part 40, so that the locking part 40 is arranged in the locking part receptacle 54 in the locking position. In this way, the pivot levers 12 can be arranged on both sides of the locking part 40 and can engage on both sides in the opposite recesses 38 of the locking part 40. In this way, a larger number of pivot levers can be used in a given installation space. In addition, greater vibration resistance can be achieved through the positive locking on both sides. In addition, greater manipulation resistance can be achieved through the positive locking towards the center of the pivot lever 12.

Furthermore, the pivot arms 28 are arranged such that one or more of the pivot arms 28 have an opposite direction of rotation from the locking position to the unlocking position than other pivot arms. Preferably, as in 1e 40 swivel arms 28 with opposite directions of rotation are provided on each side of the locking part. In this way, the security against manipulation and/or vibration can be further improved. In addition, such an arrangement enables a larger number of swivel arms 28 to be accommodated in a given space.

On its upper side, the pivot lever 12 has a key support contour 56 which is adapted to the key contour 58 on the underside of the key unit 4 corresponding to the pivot lever device 2. The key support contour 56 has in particular depressions 60, for example two oppositely extending depressions, the shapes of which are adapted to corresponding elevations 62 of the key contour 58, and/or vice versa. In this way, the correct alignment of the key contour 58 to the key support contour 56 is facilitated.

The key support contour 56 and the key contour 58, in particular the depressions 60 and elevations 62, are preferably adapted such that the key contour 58 and the key support contour 56 only fit together in exactly one orientation of the key unit 4 and the pivot lever device 2. In the present exemplary embodiment, the depressions 60 and elevations 62 have, for example, mutually corresponding inclined surfaces 64, 66, which only come into contact in a predetermined orientation of the key contour 58 and the key support contour 56.

The key unit 4 corresponding to the pivot lever device 2 has a body 70 in which unlocking magnets 72 corresponding to the locking magnets 50 are provided. The respective position and polarity of the locking magnets 50 and the corresponding unlocking magnets 72 are adapted to one another in such a way that when the key unit 4 with the key contour 58 comes to rest on the key support contour 56 in a predetermined orientation, the unlocking magnets 72 exert a magnetic force on the respectively assigned locking magnets 50, which overcomes the holding force between the locking magnets 50 and the securing element 52 and the respective Swivel arms 28 from the locking position ( 1e) into the unlocking position ( 2c ) so that the pivot lever 12 moves from the locking position ( 1a) into the operating position ( 2a) The swivel arms 28 are in the unlocked position ( 2c ) are preferably completely retracted into a release receptacle 74 of the pivot lever 12 and thus do not protrude laterally beyond the pivot lever 12 into the locking part receptacle 54. In this way, damage to the pivot arms 28 can be prevented when the pivot lever 28 is folded out into the actuating position or when the pivot lever 28 is folded in into the locking position.

A pivoting of all pivot arms 28 from the locking position ( 1e) into the unlocking position ( 2c ) only occurs when the unlocking magnets 72 of the key unit are adapted to the locking magnets 50 in terms of position and polarity. With another key unit that does not have a corresponding unlocking magnet 72 for at least one of the locking magnets 50 or whose corresponding unlocking magnet has an incorrect position and/or polarity, the pivot arm 28 belonging to the respective locking magnet 50 is not moved into the unlocking position, so that an adjustment of the pivot lever 12 from the locking position to the actuating position is blocked in a form-fitting manner.

In this way, unauthorized adjustment of the pivot lever 12 from the locking position to the actuating position can be reliably prevented, since this is only possible with a suitable key unit.

The polar alignment is in the 1d -f and 2b , as in the figures of the other embodiments, are marked by different hatching. The magnetic north pole is marked by a dot hatching and the magnetic south pole by a cross hatching.

With N swivel arms - with a given position of the locking magnets 50 - basically 2 ^N combinations are conceivable, ie different pairs of swivel lever devices 2 with corresponding key units, whereby preferably the two combinations in which the pole directions of the locking magnets 50 are each identically aligned (north poles in one direction, south poles in one direction) are preferably dispensed with in favor of manipulation security, so that 2 ^N - 2 combinations remain.

Combinations that are symmetrical by 180° are prevented in system 6 by the key support contour 56 and the key contour 58. Due to the inclined surfaces 64, 66, the key support contour 56 and the key contour 58 partially protrude from one another when the key unit 4 is rotated by 180°, as a result of which the magnetic force of the unlocking magnets 72 is sometimes no longer sufficient to overcome the holding force of the locking magnets 50, so that the pivot lever 12 - a theoretically suitable unlocking magnet combination when the key unit is rotated by 180° - remains locked in the locking position.

The provision of the swivel arms 28 with a defined locking element axis, which can be swiveled in a defined manner by magnetic interaction with a locking magnet 50 spaced from the locking element axis, has proven to be very reliable and low-interference. In particular, the defined swivel movement of the swivel arms 28 about the locking element axis by the leverage of the locking magnet 50 can prevent the locking elements 24 from jamming.

In order to enable the pivot lever 12 to be folded into the locking position even when the key unit is removed without damaging the pivot arms 28, the pivot arms 28 and the locking element 40 have mutually corresponding contours 76, 78 in the form of sliding surfaces which slide against one another when the pivot lever 12 is adjusted into the locking position, for example when a pivot arm 28 is in the locking position, so that the pivot arms 28 are pivoted in the direction of the unlocking position and enable the pivot lever 12 to be adjusted into the locking position.

The 4a -f show a second embodiment of the actuating device, namely in the form of a rotary closure, as well as a second embodiment of the system in different views. 4a shows a perspective view of the twist lock 102 and the key unit 104, which together form the system 106. 4b shows a top view. 4c shows a sectional view corresponding to the 4b cutting plane designated “IVc”. 4d shows a sectional view corresponding to the 4c cutting plane designated “IVd”. 4e shows a sectional view corresponding to the 4c cutting plane designated “IVe”. 4f shows a locking element in perspective view.

The 5a -c show the system 106 with the twist lock 102 and the key unit 104 with the key unit 104 placed on the twist lock 102. 5a shows a sectional view with a 4c corresponding cutting plane. 5b shows a view of the key unit 104 from below. 5c shows a sectional view corresponding to the 5a cutting plane designated “Vc”.

The rotary closure 102 has a housing 108 and an actuating element 110 in the form of a locking core rotatably mounted in the housing 108 about a rotation axis 109.

The housing 108 has a cylindrical section 112 with which the housing can be inserted through a recess 114, for example a hole, in a thin wall 116, for example a sheet metal door, so that it comes into contact with the wall 116 with a contact collar 118. The rotary closure 102 can be fixed to the wall 116 by screwing a lock nut 120 onto the external thread 122 provided on the cylindrical section 112.

The locking core 110 is designed at a first end 126 accessible from a front side 124 of the rotary lock 102 for the torque-transmitting attachment of the key unit 104. In the present embodiment, the locking core 106 has a contour part 128 for this purpose, which has a circumferential contour 130 delimiting the contour part 128 in the circumferential direction, between which the contour part 128 is flat. The key unit 104 has an inner contour 132 corresponding to the circumferential contour 130. The circumferential contour 130 and inner contour 132 are designed for torque-transmitting coupling, in the present embodiment with asymmetrical contours.

Such a contour part 128 enables a very flat design on the front 124. This increases safety by preventing the device from getting caught on protruding parts and also offers increased protection against vandalism since there are fewer attack surfaces caused by protruding parts.

At the end 134 opposite the first end 126, the locking core 110 can drive a locking mechanism. In the present embodiment, the rotary lock 102 is designed as a cam lock and accordingly a rotary tongue 136 is connected to the locking core 110 in a rotationally fixed manner.

In order to prevent unauthorized rotation of the locking core 110 between a closed position in which, for example, the rotary tongue 136 engages behind a counter surface of a frame surrounding the wall 116 and blocks opening of the wall 116, into an open position in which the rotary tongue 136 and the counter surface disengage and allow opening of the wall 116, a locking mechanism 142 is provided for securing the locking core 110 against unauthorized rotation.

The locking mechanism 142 comprises a plurality of locking elements 144, in the present embodiment eight locking elements 144, which are positioned around the axis of rotation 109 of the locking core 110. The locking elements 144 are each adjustable between a locking position ( 4c&d ), in which the locking elements 144 positively block rotation of the locking core 110, and an unlocking position ( 5a&c ), in which the locking elements 144 allow rotation of the locking core 110.

For this purpose, the individual locking elements 144 each have a pivot arm 148 mounted about a locking element axis 146, which can be pivoted from the locking position to the unlocking position. In the present embodiment, the pivot arms 148 have lateral bearing shafts 150 for this purpose, with which they are mounted in corresponding bearing receptacles 152 on the locking core 110.

Furthermore, the pivot arms 148 have blocking sections 154 which, in the locking position of the respective pivot arm 148, engage in a respective locking receptacle 156 of the housing 108.

Furthermore, the pivot arms 148 each have a first stop surface 158 and a second stop surface 160, wherein the first stop surface 158 strikes a counter surface 162 of the locking core 110 when the locking position is reached, thereby defining the locking position, and wherein the second stop surface 160 strikes a counter surface 164 of the locking core 110 when the unlocking position is reached, thereby defining the unlocking position. The stop surfaces 158, 160 and the corresponding counter surfaces 162, 164 limit the pivoting movement of the individual pivot arms 148, thereby ensuring a reliable and repeatable change between the locking and unlocking positions.

A respective locking magnet 166 is also arranged on the swivel arm 148 of the individual locking elements 144, spaced from the respective locking element axis 146, so that a 166 acting magnetic force via the lever between the position of the locking magnet 166 and the locking element axis 146 can cause the pivot arm 148 to pivot between the locking and unlocking positions.

The locking magnets 166 are arranged on the pivot arms 148 in respective locking magnet receptacles 168 of the pivot arms 148.

The rotary lock 102 has a locking element 170 which basically keeps the swivel arms 148 in the locking position ( 4c -d). In the present embodiment, the securing element 170 is designed in the form of a circumferential steel ring arranged in the housing 108, which also forms the base of the locking receptacles 156. A magnetic attraction force acts between the locking magnets 166 and the securing element 170, which basically holds the pivot arms 148 in the locking position (holding force).

The key unit 104 corresponding to the rotary lock 102 has a body 180 in which unlocking magnets 182 corresponding to the locking magnets 166 are provided. The respective position and polarity of the locking magnets 166 and the corresponding unlocking magnets 182 are adapted to one another in such a way that when the key unit 104 with the inner contour 132 in a predetermined orientation comes to rest on the peripheral contour 130, the unlocking magnets 182 cause a magnetic force on the respectively assigned locking magnets 166, which overcomes the holding force between the locking magnets 166 and the securing element 170 and moves the respective pivot arms 148 from the locking position ( 4c -d) into the unlocking position ( 5a&c ) so that the locking core 110 can be rotated in the housing 108, in particular from a closed position to an open position.

A pivoting of all pivot arms 148 from the locking position ( 4c -d) into the unlocking position ( 5a&c ) only occurs when the unlocking magnets 182 of the key unit 104 are adapted to the locking magnets 166 in terms of position and polarity. With another key unit that does not have a corresponding unlocking magnet 182 for at least one of the locking magnets 166 or whose corresponding unlocking magnet has an incorrect position and/or polarity, the pivot arm 148 belonging to the respective locking magnet 166 is not moved into the unlocking position, so that rotation of the locking core 110 in the housing 108 is blocked in a form-fitting manner.

In this way, unauthorized rotation of the locking core 110, for example from a closed position to an open position, can be reliably prevented, since this is only possible with a suitable key unit.

With N swivel arms - with a given position of the locking magnets 50 - basically 2 ^N combinations are conceivable, ie different pairs of rotary locks 102 with corresponding key units, whereby preferably the two combinations in which the pole directions of the locking magnets 166 are each identically aligned (north poles in one direction, south poles in one direction) are preferably dispensed with in favor of manipulation security, so that 2 ^N - 2 combinations remain.

In order to enable the safe use of rotationally symmetrical combinations, the peripheral contour 130 and the inner contour 128 are preferably designed to be asymmetrical in such a way that the key unit 104 can only be placed on the rotary lock 102 in a predetermined position.

The provision of the pivot arms 148 with a defined locking element axis, which can be pivoted in a defined manner by magnetic interaction with a locking magnet 166 spaced from the locking element axis, has proven to be very reliable and low-interference. In particular, the defined pivoting movement of the pivot arms 148 about the locking element axis by the leverage of the locking magnet 166 can prevent the locking elements 144 from jamming.

The 6a -c show a third embodiment of the actuating device in the form of a rotary lock and a third embodiment of the system in different views. The system 206 with the rotary lock 202 and the key unit 204 has a similar structure and a similar mode of operation as the system 106 from 4a -d and 5a -c. Corresponding elements, even if they may differ in their geometrical design, are provided with the same reference symbols as in 4a -d and 5a -c and reference is made to the above description of these figures.

6a shows a sectional view of the system 206 corresponding to the sectional view of the system tems 106 from 4c . 6b shows a sectional view corresponding to the 6a cutting plane designated “VIb”. 6c shows a locking element in perspective view.

The rotary closure 202 differs from the rotary closure 102 by a different design of the locking elements 224. The locking elements 224 are arranged like the locking elements 224 around the axis of rotation 109 of the locking core 110 and have pivot arms 248 which can be pivoted about a respective locking element axis 146 between a locking position ( 6a&c ), in which the locking elements 224 engage with a blocking section 154 in a respective locking receptacle 156 of the housing 108 and in this way positively block rotation of the locking core 110, and an unlocking position ( 7a&c ), in which the blocking sections 154 are disengaged from the locking receptacles 156 and in this way allow rotation of the locking core 110, are pivotable.

In the pivot arms 248, the locking magnets 166 and the blocking sections 154 are arranged on different sides of the pivot arms 248 with respect to the respective locking element axis 146.

Furthermore, the twist lock 202 differs from the twist lock 102 by a different positioning and design of the securing element 270, which in the twist lock 202 is designed as a steel ring integrated into the contour part 128.

The twist lock 202 also differs from the twist lock 102 in that the contour part 128 is formed separately from the locking core 110. The contour part 128 and the locking core 110 are connected to one another in a rotationally fixed manner by means of a screw which extends from the end 134 of the locking core 110 through the locking core 110 to the contour part 128 and is screwed into it.

In the case of the rotary closure 102, it is advantageous that the securing element 170 is arranged in the circumferential direction in the housing 108, whereby in particular the contour part 128 can be made flatter than in the case of the rotary closure 202, in which the securing element 270 is integrated into the contour part 128.

In the rotary lock 202, it is advantageous that the locking magnets 166 are spatially separated from the blocking sections 154, whereby the blocking sections 154 can be made more robust.
