Patent Document 1

[0005] Against this background, the object underlying the present invention is to provide an improved actuating device that enables more reliable locking and unlocking.

[0006] The aforementioned objective is solved by an actuator comprising a housing and an actuator element, the actuator element being displaceable between a first actuator position and a further actuator position relative to the housing, and a locking mechanism provided to fix the actuator element against unauthorized displacement from the first actuator position to the further actuator position, the locking mechanism comprising at least one locking element displaceable between a locked position for reliably preventing displacement of the actuator element from the first actuator position to the further actuator position and an unlocked position for allowing displacement of the actuator element from the first actuator position to the further actuator position, the locking element comprising at least one locking magnet, the locking magnet for displacing the locking element from the locked position to the unlocked position by magnetic interaction between the locking magnet and at least one unlocking magnet of a corresponding key unit, the locking element comprising a swivel arm, the swivel arm being rotatable about the axis of the locking element and rotatable from the locked position to the unlocked position, and the locking magnet being positioned on the swivel arm at a distance from the axis of the locking element.

[0007] The locking element comprises a rotatably assembled swivel arm, on which a locking magnet is positioned. Thus, the locking element is formed in particular by the swivel arm and the locking magnet positioned on this swivel arm, thereby providing a rotatable locking element with a locking magnet. The locking element may also comprise a number of locking magnets.

[0008] By providing a swivel arm that is assembled to rotate around the axis of the locking element and can be rotated from the locked position to the unlocked position, a locking element is provided that is reliably guided between the locked and unlocked positions, thereby reliably preventing the locking element from tilting even if there is force acting on it due to undesirable environmental impacts or acts of vandalism.

[0009] The locking magnet is positioned on the swivel arm at a distance from the axis of the locking element. In particular, the center point of the locking magnet, or the central axis of the locking magnet extending through the north and south poles of the locking magnet, is positioned at a distance from the axis of the locking element.

[0010] A locking magnet positioned on the swivel arm at a distance from the axis of the locking element generates a lever action on the swivel arm through magnetic interaction with the locking magnet, thereby allowing the swivel arm to rotate, particularly between the locked position and the unlocked position.

[0011] The locking magnet is preferably positioned at a distance from the locking element axis such that the locking magnet is completely outside the locking element axis. As a result, the lever arm becomes longer. However, as long as the center point or central axis of the locking magnet is located at a distance from the locking element axis, it is also possible for the locking element axis to extend through the region to the side of the locking magnet.

[0012] The swivel arm is preferably made of a non-ferromagnetic material, particularly aluminum or plastic, so that the magnetic interaction between the locking magnet and the unlocking magnet of the corresponding key unit is not weakened as much as possible or not weakened at all.

[0013] The aforementioned problems are further solved by a system, according to the present invention, comprising the above-described actuator or embodiment thereof and a corresponding key unit, the corresponding key unit having at least one unlocking magnet corresponding to at least one locking magnet of the actuator.

[0014] The key unit is preferably designed such that the magnetic interaction between at least one unlocking magnet and at least one locking magnet, when the key unit is supported on the key contact surface of the actuator, causes at least one locking element to rotate to the unlocked position.

[0015] Each embodiment of the actuator described above and / or the system described above, or both, is preferably designed and / or used as part of an access control device, for example, on a flap or door, particularly a thin-walled door, such as a sheet metal door.

[0016] Different embodiments of the actuator and system are described below, but each embodiment applies independently to the actuator and system. Furthermore, the individual embodiments may be combined with each other as needed.

[0017] In one embodiment, the swivel arm has a blocking section that reliably prevents the displacement of the actuating element from a first actuating element position to a further actuating element position in the locked position, and allows displacement in the unlocked position. For this purpose, in the locked position, for example, the blocking section is engaged with a housing provided in the housing, thereby preventing the actuating element from being displaced to a further actuating element position.

[0018] The blocking section may be positioned on the same side of the swivel arm as the locking magnet, with respect to the locking element axis. Alternatively, the blocking section and the locking element may be positioned on different sides of the swivel arm with respect to the locking element axis. In this way, the blocking section can be positioned further away from the locking magnet, which allows for a more robust design of the blocking section.

[0019] In one embodiment, the slewing arm has a stop surface that strikes a corresponding surface when the slewing arm rotates to a locked or unlocked position. Thus, the locked or unlocked position can be set as a predetermined end position of the slewing arm. In this way, a more reliable and smoother displacement of the slewing arm can be achieved. The corresponding surface may be formed, for example, by a housing or an actuation element.

[0020] Preferably, the slewing arm has a first stop surface that abuts a first corresponding surface when the slewing arm rotates to a locked position, and a second stop surface that abuts a second corresponding surface when the slewing arm rotates to an unlocked position. For example, the first corresponding surface may be formed by the housing and the second corresponding surface may be formed by the actuating element, or vice versa.

[0021] In one embodiment, the locking mechanism has at least two locking elements, each comprising a rotatably mounted swivel arm and a locking magnet positioned on the swivel arm. This improves protection against improper displacement of the actuating element from a first actuating element position to a further actuating element position. This is even more true when the locking mechanism comprises at least four, preferably at least six, and especially at least eight locking elements, each comprising a rotatably mounted swivel arm and a locking magnet positioned on the swivel arm. Regardless of the number of locking elements, it is useful to be able to adjust each of these locking elements between a locked position and an unlocked position. Alternatively or additionally, for ease of operation of the locking mechanism, it is advisable that each locking element comprises at least one locking magnet.

[0022] In one embodiment, with respect to the direction from the locked position to the unlocked position of each locking element, the orientation of the poles of at least two of the locking magnets of different locking elements is different from that of the other locking elements. This further improves protection against unauthorized displacement of the operating elements. In particular, this allows coding to be performed, making it more difficult for an unauthorized person to move all the locking elements to their respective unlocked positions. Preferably, the orientation of the poles of at least two adjacent locking magnets is different from that of the other.

[0023] In one embodiment, the pivoting directions of at least two mutually different locking elements from the locking position to the unlocking position of each locking element are different from each other. In some constructive embodiments, more locking elements can thus be accommodated within a given installation space. Furthermore, the vibration resistance of the locking mechanism can thus be improved.

[0024] 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 latching position, and the further actuating element position is an actuating position for actuating the locking device. In particular, the actuating device may be a pivoting lever device.

[0025] Accordingly, the above-mentioned object is achieved in particular by an actuating device for actuating a locking device, in particular a pivoting lever device, comprising a housing and an actuating element for actuating the locking device, wherein the actuating element is displaceable relative to the housing between a latching position and an actuating position for actuating the locking device, a locking mechanism is provided for securing the actuating element against unauthorized displacement from the latching position to the actuating position, the locking mechanism comprises at least one locking element displaceable between a locking position for reliably blocking displacement of the actuating element from the latching position to the actuating position and an unlocking position for allowing displacement of the actuating element from the latching position to the actuating position, the locking element comprises at least one locking magnet for displacing the locking element from the locking position to the unlocking position by magnetic interaction between the locking magnet and at least one unlocking magnet of a corresponding key unit, the locking element comprises a pivoting arm, the pivoting arm is assembled to be pivotable about a locking element axis and can pivot from the locking position to the unlocking position, and the locking magnet is arranged on the pivoting arm at a distance from the locking element axis.

[0026] It has been found that the described locking mechanism provided with one or more locking elements each having a pivot arm is particularly advantageously suitable for providing an actuating element that can reliably lock and unlock in the latching position. In particular, an actuating device according to Patent Document 1 can thus be improved.

[0027] In one embodiment, the actuating element is designed as a pivot lever, which is pivotable about a rotational actuation axis relative to the housing in the actuating position. The pivot lever is preferably connected to a rotatable actuation shaft, which is driven by pivoting the pivot lever about the rotational actuation axis, whereby for example a locking device connected to the actuation shaft, such as a single-point or multi-point locking device, can be actuated.

[0028] In one embodiment, the housing has a recess that accommodates the actuating element in the latching position. In this way, when the actuating element is not in use, it can be folded into the recess, whereby a flatter design can be achieved, and the risk of unintentional catching or vandalism to the actuating element can be reduced. For this purpose, the actuating element can be displaced from a first actuating element position to a further actuating element position and / or vice versa, in particular by folding the actuating element about a folding axis.

[0029] In one embodiment, the housing has a housing plane in which the recess is recessed, and the actuating element has a flat upper surface that is substantially parallel, preferably flush, with the housing plane when the actuating element is accommodated in the recess. The upper surface of the actuating element preferably forms an angle of less than 5°, preferably less than 2°, with respect to the housing plane. Additionally or alternatively, the upper surface of the actuating element preferably protrudes beyond the housing plane by less than 10 mm, preferably less than 5 mm. A particularly flat design is thus enabled.

[0030] In one embodiment, the housing has a latching portion, and the actuating element has a latching portion housing corresponding to the latching portion. In the latched position of the actuating element, the latching portion is housed within the latching portion housing, and in the locked position, a locking element engages within a recess of the latching portion. Thus, one or more locking elements below the actuating element provide secure locking, making it more difficult to tamper with the actuating device.

[0031] In one embodiment, the swivel arm and the housing, particularly the locking portion, are provided with corresponding contours, particularly sliding surfaces, that interact with each other so as to allow the swivel arm to rotate, particularly in the direction of the unlocked position, when the actuating element is displaced from a further actuating element position, particularly the operating position, to a first actuating element position, particularly the locking position. Thus, when the key unit is removed, the actuating element can be moved to the first actuating element position, particularly the locking position, without the swivel arm preventing such displacement. Thus, in the case of a swivel lever device, for example, the swivel lever can be folded into a recess provided in the housing, even without the key unit.

[0032] For example, corresponding inclined sliding surfaces or inclined sliding surfaces and corresponding edges that slide relative to each other when the actuation element is moved to the first actuation element position, and that cause the swivel arm to swivel toward the unlocked position, for example, may be provided on the swivel arm and the housing, in particular the latching portion, as corresponding contours.

[0033] In one embodiment, the actuation element has a key support contour that is freely accessible in the locked position, and at least one locking magnet is arranged to displace the locking element from the locked position to the unlocked position when the corresponding key unit is supported on the key support contour. This makes it more difficult to improperly operate the actuation device with a geometrically incorrect key unit. Furthermore, the key support contour makes it easier for the user to properly position the key unit and, consequently, operate the actuation device. Preferably, the key contour has an asymmetry such that the corresponding key unit can only be positioned on the key support contour in one direction.

[0034] In one embodiment, the locking mechanism comprises at least two, optionally at least four, preferably at least six, and particularly at least eight locking elements, of which at least two are positioned on opposite sides of the longitudinal axis of the actuating element and / or the longitudinal axis of the housing. This improves protection against violent displacement of the actuating element from the locked position to the actuating position. This is further true when at least two groups of locking elements, each comprising at least two, particularly at least three locking elements, are positioned on opposite sides of the longitudinal axis of the actuating element and / or the longitudinal axis of the housing.

[0035] In one embodiment, the locking mechanism comprises at least two, optionally at least four, preferably at least six, and particularly at least eight locking elements, of which at least two locking elements are arranged at a distance from each other along the longitudinal axis of the actuating element and / or the longitudinal axis of the housing. In this way, the actuating element can be securely held in a locked position at different positions in the housing along its longitudinal axis. This also improves protection against the actuating element being violently moved from the locked position to the actuating position. This is especially true when at least two locking elements of the group of locking elements are arranged at a distance from each other along the longitudinal axis of the actuating element and / or the longitudinal axis of the housing.

[0036] Preferably, the distance between adjacent locking elements along the longitudinal axis of the actuating element and / or housing is equal. This makes it easier to manufacture the actuating device or key unit.

[0037] In one embodiment, when the actuating element is engaged, the locking element is housed within the housing and / or actuating element such that external access to the locking element is impossible when it is in the locked and / or unlocked positions. This further improves protection against external damage to the locking mechanism.

[0038] Alternatively or additionally, when the actuating element is in the engaged position, it may be specified that at least one locking element is housed within the housing and / or actuating element such that the locking element is not visible from the outside when it is in the locked and / or unlocked positions. This improves protection against improper displacement of the locking element from the locked to the unlocked position.

[0039] Regardless of this, in the engaged position of the operating element, it may be appropriate that the locking element is partially housed within the housing when in the locked position, partially housed within the operating element, and / or housed within the housing or operating element when the locking element is in the unlocked position.

[0040] In one embodiment, when the locking element is in the unlocked position, preferably regardless of the position of the operating element, it is housed within the operating element or the unlocked housing of the housing. In this way, damage to the locking element can be easily prevented when it is in the unlocked position.

[0041] In one embodiment, when the operating element is in the engaged position, the locking element is securely engaged with the housing or the locking housing of the operating element. In this way, the displacement of the operating element from the engaged position to the operating position can be structurally and easily and reliably locked and prevented.

[0042] In one embodiment, the locking mechanism includes at least one fixed element for automatically displacing at least one locking element from the unlocked position to the locked position when the actuating element is moved to the latched position. This prevents at least one locking element from unintentionally remaining in the unlocked position when the actuating element is moved to a further actuating element position, particularly from the actuating position to the first actuating element position, particularly the latched position.

[0043] At least one fixed element may be designed to automatically displace at least one locking element from the unlocked position to the locked position when the actuating element is moved to a first actuating element position, particularly the latched position. In this way, when the actuating element is moved to a first actuating element position, particularly the latched position, the locking element can be automatically displaced from the unlocked position to the locked position by the fixed element. This improves protection against unauthorized displacement of the actuating element from the first actuating element position, particularly the latched position, to further actuating element positions, particularly the actuating position.

[0044] Alternatively or additionally, at least one fixing element may be designed to hold at least one locking element in the locked position when the actuating element is in a first actuating element position, particularly the latched position. This can also contribute to improved protection against improper displacement of the actuating element from the first actuating element position, particularly the latched position, to further actuating element positions, particularly the actuating position.

[0045] Regardless of this, in cases involving multiple locking elements, it is sometimes advisable, for simplification, to assign at least one fixed element to each of the numerous locking elements. This eliminates the need to provide a separate fixed element for each locking element.

[0046] The locking element may be attached to the actuarial element. For ease of operation of the locking mechanism, at least one fixing element is preferably attached to the housing. Alternatively or additionally, at least one fixing element may be located at least partially, and at least substantially, within the housing or actuarial element. This ensures that external access to the locking element is impossible, thereby improving protection against damage to the locking mechanism caused by vandalism and improper displacement of the locking element from the locked position to the unlocked position.

[0047] In one embodiment, at least one fixed element is formed from a ferromagnetic material, and preferably, the locking element is automatically displaceable from the unlocked position to the locked position by magnetic interaction between the locking magnet and the fixed element when the actuating element is displaced to the first actuating element position, particularly the latched position. This enables not only a particularly simple design of the locking mechanism but also reliable operation.

[0048] For the same reasons, alternatively or additionally, it may be advantageous that, at the first actuating element position of the actuating element, particularly the latched position, at least one locking element is held in the locked position by a magnetic interaction between at least one locking magnet and at least one fixed element.

[0049] In general, the automatic displacement of a locking element and / or its retention in the locked position can be achieved at least partially by the magnetic interaction between the locking magnet and the fixed element. However, for the reasons mentioned above, it is particularly preferable that the automatic displacement of the locking element and / or its retention in the locked position is at least substantially influenced by the magnetic interaction between the locking magnet and the fixed element.

[0050] In this specification, a ferromagnetic material is understood to be a material that is attracted to an external magnetic field. In principle, the fixed element may be designed as a permanent magnet. However, for the sake of simple and reliable operation of the locking mechanism, it is preferable that the fixed element itself does not generate a magnetic field.

[0051] In one embodiment, the actuation device is a lock, particularly a rotary bolt lock, such as a sash lock, and the actuation element is a lock core rotatably mounted within a housing, the lock core being configured to torque-transmit a corresponding key unit at a first end accessible from the front side of the lock, the first actuation element position being a first rotational position of the lock core within the housing, particularly an open or closed position, and a further actuation element position being a second rotational position of the lock core within the housing, particularly a closed or open position.

[0052] Therefore, the above-mentioned objective is particularly important for a lock, especially a rotary bolt lock, such as a sash lock, comprising a lock housing and a lock core rotatably assembled within the lock housing, the lock core being designed to have a key torque-transmission mounted at a first end accessible from the front side of the lock, and a locking mechanism provided to fix the lock core against unauthorized rotation between an open position and a closed position, the locking mechanism having a locking position to reliably prevent rotation of the lock core within the lock housing between an open position and a closed position, and the lock core between an open position and a closed position The lock is resolved by a lock comprising at least one locking element displaceable between a locked position and an unlocked position to allow rotation of the locking element, the locking element comprising at least one locking magnet, the locking magnet being moved from the locked position to the unlocked position by magnetic interaction between the locking magnet and at least one unlocking magnet of the corresponding key, the locking element comprising a swivel arm, the swivel arm being rotatable about the axis of the locking element and rotatable from the locked position to the unlocked position, and the locking magnet being positioned on the swivel arm at a distance from the axis of the locking element.

[0053] The described locking mechanism, comprising one or more locking elements with each swivel arm, also proved particularly advantageous for providing a rotary bolt with a locking core rotation that can be reliably locked and unlocked.

[0054] In one embodiment, the locking mechanism comprises at least two, preferably at least three, locking elements, each comprising a rotatably mounted swivel arm and a locking magnet positioned on the swivel arm, wherein these locking elements are preferably arranged to surround the rotation axis of the locking core. This improves the protection of the rotary bolt against tampering. Furthermore, this allows for a greater number of swivel arms equipped with locking magnets, thereby increasing the number of different pairs of rotary bolts and key units.

[0055] In one embodiment, the lock core has a contoured portion at a first end, the contoured portion having a circumferential contour for torque-transmitting mounting of a corresponding key unit, which defines the contoured portion circumferentially, and is preferably formed flat between the circumferential contours. Thus, a particularly flat design is achieved that particularly enhances robustness against vandalism.

[0056] In one embodiment, a fixing element is provided, which is designed to hold at least one locking element in the locked position when the key is removed, particularly by magnetic interaction between the fixing element and the locking element. This improves the vibration resistance of the lock, so that even if there is mechanical vibration or oscillation when the key is removed, the locking element is safely held in the locked position, and thus prevents the lock from opening or closing when the key is removed. In the case of numerous locking elements, the fixing element may preferably be designed to hold numerous locking elements in the locked position by magnetic interaction between the fixing element and the locking elements when the key is removed.

[0057] The magnetic interaction between a fixed element and a locking element or a number of locking elements is preferably a magnetically attractive interaction. However, it is also possible for the magnetic interaction between a fixed element and a locking element or a number of locking elements to be a magnetically repulsive interaction.

[0058] For example, the locking element may be equipped with a magnet, and the fixing element may be a magnet, or it may be made of a ferromagnetic material in the form of a ferromagnetic metal plate or metal ring, for example, a steel plate or steel ring.

[0084] Figures 1A to 1E show first exemplary embodiments of the actuator in the form of a swivel lever device and first exemplary embodiments of the system in various diagrams. Figure 1A shows a perspective view of the swivel lever device 2 and key unit 4, which together form system 6. Figure 1B shows a top view. Figure 1C shows a cross-sectional view corresponding to the cross-sectional plane indicated as "Ic" in Figure 1B. Figure 1D shows a view of the key unit 4 from below, with several hidden elements indicated by dashed lines. Figure 1E shows a cross-sectional view corresponding to the cross-sectional plane indicated as "Ie" in Figure 1C. Figure 1F shows a perspective view of the locking element.

[0085] The swivel lever device 2 comprises a housing 10 and an operating element 12 in the form of a swivel lever.

[0086] The swivel lever 12 may be adjusted between a locked position (Figures 1A to 1E) and an operating position (Figures 2A to 2C) with respect to the housing 10, with the swivel lever bending axis 17 as the center.

[0087] Figures 2A to 2C show a system 6 comprising a slewing lever device 2 and a key unit 4, with the slewing lever 12 in the operating position. Figure 2A shows a perspective view, and Figure 2B shows a cross-sectional view having the same cross-sectional plane as Figure 1C. Figure 2C shows a cross-sectional view corresponding to the cross-sectional plane shown as "IIc" in Figure 2B.

[0088] In the operating position, the swivel lever 12 may be rotated around the operating axis 13, thereby transmitting rotational motion to the operating axis 16 which is connected to or may be connected to the locking device 14, such as a one-point or multi-point locking device for an entry / exit device like a door or flap. In this way, the locking device 14 can be activated by rotating the swivel lever 12 around the operating axis 13. Figure 3 illustrates the swivel position (operating position) of the swivel lever 12 in a perspective view.

[0089] In the locked position (Figures 1A to 1E), the swivel lever 12 is housed within the recess 18 of the housing 10. This prevents unintended operation of the swivel lever 12. Furthermore, this allows for a flat design, which prevents, for example, unintended snagging of the protruding swivel lever 12.

[0090] The flat design of the slewing lever device 2 is also achieved, in particular, by having a flat upper surface 20 that is parallel to the housing plane 21 when the slewing lever 12 is housed within the recess 18.

[0091] The swivel lever 12 is further secured against unauthorized displacement from the locked position (Figures 1A to 1E) to the operating position (Figures 2A to 2C). For this reason, the swivel lever device 2 has a locking mechanism 22 that prevents the swivel lever device 2 from being moved from the locked position to the operating position without the key unit 4.

[0092] The locking mechanism 22 comprises a plurality of locking elements 24, eight locking elements in the illustrated exemplary embodiment, and each of these locking elements 24 may be displaced between a locked position (Figure 1E) in which the locking element 24 reliably prevents the displacement of the swivel lever 12 from the locked position to the operating position, and an unlocked position (Figure 2C) in which the locking element 24 allows the displacement of the swivel lever 12 from the locked position to the operating position.

[0093] For this purpose, each locking element 24 has a swivel arm 28 that can be rotated from a locked position to an unlocked position, which is assembled around the locking element axis 26. For this purpose, in the illustrated exemplary embodiment, the swivel arm 28 has a lateral support shaft 30, which aligns the swivel arm 28 with a corresponding support housing 32 provided on the swivel lever 12.

[0094] Furthermore, the swivel arm 28 has a blocking section 34, which engages with a locking housing 36 of the housing 10 in the locked position of each swivel arm 28, which in the illustrated exemplary embodiment is formed by two recesses 38 opposite each other of a hooking portion 40 protruding into a recess 18.

[0095] Furthermore, each slewing arm 28 has a first stop surface 42 and a second stop surface 44, the first stop surface 42 colliding with a corresponding surface 46 of the slewing lever 12 when the locked position is achieved, thereby defining the locked position, and the second stop surface 44 colliding with a corresponding surface 48 of the slewing lever 12 when the unlocked position is achieved, thereby defining the unlocked position. The slewing motion of each slewing arm 28 is restricted by the stop surfaces 42, 44 and the corresponding surfaces 46, 48, thereby ensuring reliable and repeatable changes between the locked and unlocked positions. In the illustrated example, the first and second corresponding surfaces 46, 48 are identical to each other. However, the first and second corresponding surfaces may be different from each other.

[0096] Furthermore, each locking magnet 50 is positioned on the pivot arm 28 of each locking element 24 at a distance from the respective locking element axis 26. This allows the pivot arm 28 to rotate between the locked position and the unlocked position via a lever between the position of the locking magnet 50 and the locking element axis 26, due to the magnetic force acting on the locking magnet 50.

[0097] In the swivel arm 28, the lock magnets 50 are arranged within each lock magnet housing 51 of the swivel arm 28.

[0098] The swivel lever device 2 basically has a fixing element 52 that holds the swivel arm 28 in the locked position (Figure 1E). In the illustrated exemplary embodiment, this fixing element 52 is in the form of a steel element located within the latching portion 40. A magnetic attractive force (holding force) acts between the lock magnet 50 and the steel element 52, which basically holds the swivel arm 28 in the locked position.

[0099] The swivel lever 12 has a locking portion housing 54 on its underside that fits the locking portion 40, so that in the locked position, the locking portion 40 is positioned within the locking portion housing 54. In this way, the swivel arms 28 can be positioned on both sides of the locking portion 40 and engaged with the opposite recesses 38 of the locking portion 40 on both sides. This allows for the use of more swivel arms in a given installation space. Furthermore, the secure lock on both sides can achieve greater vibration resistance. In addition, the secure lock directed towards the center of the swivel lever 12 provides greater protection against tampering.

[0100] Furthermore, the swivel arms 28 are arranged such that one or more swivel arms 28 have opposite rotation directions from the locked position to the unlocked position to another swivel arm. Preferably, as shown in Figure 1E, swivel arms 28 with opposite rotation directions to each other are provided on each side of the locking portion 40. In this way, tampering resistance and / or vibration resistance can be further improved. Moreover, such an arrangement makes it possible to accommodate a larger number of swivel arms 28 in the given space.

[0101] The swivel lever 12 has a key support contour 56 on its upper surface that is adapted to the key contour 58 on the lower surface of the key unit 4 corresponding to the swivel lever device 2. In particular, this key support contour 56 has a recess 60, for example, two recesses extending in opposite directions, and the shape of these two recesses is adapted to the corresponding protrusion 62 of the key contour 58, and / or vice versa. This facilitates proper alignment of the key contour 58 with respect to the key support contour 56.

[0102] The key support contour 56 and the key contour 58, particularly the recess 60 and the protrusion 62, are preferably fitted such that the key contour 58 and the key support contour 56 engage with each other only in one precisely aligned position between the key unit 4 and the pivot lever device 2. In the illustrated exemplary embodiment, the recess 60 and the protrusion 62 have, for example, corresponding inclined surfaces 64, 66, which contact each other only when the key contour 58 and the key support contour 56 are in a predetermined aligned position.

[0103] The key unit 4 corresponding to the swivel lever device 2 has a body 70, and within this body 70 is a locking magnet 72 corresponding to a locking magnet 50. The positions and polar orientations of the locking magnet 50 and the corresponding locking magnet 72 are adapted to each other so that when the key unit 4 is brought into contact with the key support contour 56 in a predetermined orientation by the key contour 58, the locking magnet 72 exceeds the holding force between the locking magnet 50 and the fixed element 52, moving each swivel arm 28 from the locked position (Figure 1E) to the unlocked position (Figure 2C), thereby generating a magnetic force in each assigned locking magnet 50 that allows the swivel lever 12 to rotate from the locked position (Figure 1A) to the operating position (Figure 2A). In the unlocked position (Figure 2C), the swivel arm 28 is preferably fully retracted into the locking housing 74 of the swivel lever 12 and, consequently, does not protrude laterally beyond the swivel lever 12 into the locking housing 54. In this way, damage to the slewing arm 28 can be prevented when the slewing lever 28 is folded out to the operating position or when the slewing lever 28 is folded back to the locking position.

[0104] All rotation of the swivel arm 28 from the locked position (Figure 1E) to the unlocked position (Figure 2C) occurs only when the position and polarity of the key unit's release magnet 72 are matched to the lock magnet 50. In another key unit that does not have a corresponding release magnet 72 for at least one lock magnet 50, or in another key unit that has a corresponding release magnet with an improper position and / or polar orientation, the swivel arm 28 assigned to the relevant lock magnet 50 is not moved to the unlocked position, thereby ensuring that the displacement of the swivel lever 12 from the locked position to the operating position is prevented.

[0105] In this way, unauthorized displacement of the pivot lever 12 from the locked position to the operating position can be reliably prevented, because displacement is only possible with the appropriate key unit.

[0106] In Figures 1D to 1F and Figure 2B, as in the drawings of other embodiments, the orientation of the poles is indicated by different hatching patterns. The magnetic north pole is indicated by dot hatching, and the magnetic south pole is indicated by cross hatching.

[0107] If there are N swivel arms, then, in principle, with respect to the given position of the lock magnet 50, 2 N The combination of two types of devices, namely the swivel lever device 2 and the corresponding key unit. N Different pairs are possible, which preferably eliminates two combinations where the poles of the lock magnet 50 are oriented in the same direction (N pole facing in one direction, S pole facing in one direction) in order to prevent tampering, thereby 2 N - Two combinations remain.

[0108] In system 6, combinations that are rotationally symmetric by 180° are prevented by the key support contour 56 and key contour 58. When the key unit 4 is rotated by 180°, the inclined surfaces 64 and 66 partially offset the key support contour 56 and key contour 58 from each other, and as a result, the magnetic force of the release magnet 72 is no longer sufficient to exceed the holding force of the lock magnet 50, thereby keeping the swivel lever 12, which has a combination of release magnets that theoretically matches when the key unit is rotated by 180°, locked in the latched position.

[0109] It has been proven that providing a pivot arm 28 having a specified lock element axis, which can be rotated as specified by magnetic interaction with a lock magnet 50 positioned at a distance from the lock element axis, results in extremely high reliability and a low failure rate. In particular, the specified pivoting motion of the pivot arm 28 around the lock element axis due to the lever action of the lock magnet 50 can prevent the lock element 24 from tilting.

[0110] Even when the key unit is removed, the swivel arm 28 and the locking element 40 have corresponding contours 76, 78 of sliding surfaces that slide relative to each other when the swivel arm 28 is in the locked position, for example, when the swivel arm 28 is in the locked position, thereby allowing the swivel arm 28 to rotate toward the unlocked position and the swivel lever 12 to move toward the locked position.

[0111] Figures 4A to 4F show a second exemplary embodiment of the actuator, i.e., the actuator in the form of a rotary lock, and a second exemplary embodiment of the system in various diagrams. Figure 4A shows a perspective view of the rotary lock 102 and key unit 104, which together form system 106. Figure 4B shows a top view. Figure 4C shows a cross-sectional view corresponding to the cross-sectional plane indicated as "IVc" in Figure 4B. Figure 4D shows a cross-sectional view corresponding to the cross-sectional plane indicated as "IVd" in Figure 4C. Figure 4E shows a cross-sectional view corresponding to the cross-sectional plane indicated as "IVe" in Figure 4C. Figure 4F shows a perspective view of the locking element.

[0112] Figures 5A to 5C show a system 106 comprising a rotary lock 102 and a key unit 104 assembled to the rotary lock 102. Figure 5A shows a cross-sectional view having the same cross-sectional plane as in Figure 4C. Figure 5B shows a view of the key unit 104 from below. Figure 5C shows a cross-sectional view corresponding to the cross-sectional plane indicated as "Vc" in Figure 5A.

[0113] The rotary lock 102 comprises a housing 108 and an actuation element 110 in the form of a lock core that is rotatably assembled within the housing 108 about a rotation axis 109.

[0114] The housing 108 has a cylindrical section 112 through which the housing may be inserted through a recess 114, for example, a hole, in a thin wall 116, such as a sheet metal door, thereby bringing the housing into contact with the wall 116 via a support flange 118. The rotary lock 102 can be fixed to the wall 116 by screwing a lock nut 120 onto the male threads 122 provided on the cylindrical section 112.

[0115] At the first end 126 accessible from the front side 124 of the rotary lock 102, the lock core 110 is formed to torque-transmit the key unit 104. For this purpose, in the illustrated exemplary embodiment, the lock core 106 has a contour portion 128, which has a circumferential contour 130 defining the contour portion 128 circumferentially, and the contour portion 128 is formed flat between these circumferential contours. The key unit 104 has an inner contour 132 corresponding to the circumferential contour 130. The circumferential contour 130 and the inner contour 132 are designed to have asymmetrical contours in the illustrated exemplary embodiment to connect in a torque-transmitting manner.

[0116] These contoured sections 128 enable an extremely flat design on the front surface 124. This improves safety by preventing snagging on protruding parts and also provides enhanced protection against vandalism, because there is virtually no surface area to attack due to protruding parts.

[0117] At the end 134 opposite to the first end 126, the lock core 110 may drive the locking mechanism. In the illustrated exemplary embodiment, the rotary lock 102 is designed as a latching mechanism, and accordingly, the rotating tongue 136 is connected to the lock core 110 in a way that prevents relative rotation.

[0118] For example, to prevent the lock core 110 from rotating improperly between a closed position in which the rotating tongue 136 engages with the back of a corresponding surface of the frame surrounding the wall 116, thereby preventing the wall 116 from opening, and an open position in which the rotating tongue 136 and the corresponding surface are disengaged, allowing the wall 116 to open, a locking mechanism 142 is provided to fix the lock core 110 against improper rotation.

[0119] The locking mechanism 142 comprises a plurality of locking elements 144, eight locking elements 144 in the illustrated exemplary embodiment, which are positioned to surround the rotation axis 109 of the lock core 110. Each locking element 144 is rotatable between a locked position (Figures 4C and 4D) in which the locking element 144 reliably prevents the rotation of the lock core 110, and an unlocked position (Figures 5A and 5C) in which the locking element 144 allows the rotation of the lock core 110.

[0120] For this purpose, each locking element 144 has a swivel arm 148 that can be rotated from a locked position to an unlocked position, which is assembled around the locking element axis 146. For this purpose, in the illustrated exemplary embodiment, the swivel arm 148 has a lateral support shaft 150, which aligns the swivel arm 148 with a corresponding support housing 152 provided in the lock core 110.

[0121] Furthermore, each swivel arm 148 has a blocking section 154, which engages with each lock housing 156 of the housing 108 when each swivel arm 148 is in the locked position.

[0122] Furthermore, each slewing arm 148 has a first stop surface 158 and a second stop surface 160, the first stop surface 158 colliding with a corresponding surface 162 of the lock core 110 when the locked position is achieved, thereby defining the locked position, and the second stop surface 160 colliding with a corresponding surface 164 of the lock core 110 when the unlocked position is achieved, thereby defining the unlocked position. The slewing motion of each slewing arm 148 is restricted by the stop surfaces 158, 160 and their corresponding surfaces 162, 164, thereby ensuring reliable and repeatable changes between the locked and unlocked positions.

[0123] Furthermore, each locking magnet 166 is positioned on the pivot arm 148 of each locking element 144 at a distance from the respective locking element axis 146. This allows the magnetic force acting on the locking magnet 166 to rotate the pivot arm 148 between the locked position and the unlocked position via a lever between the position of the locking magnet 166 and the locking element axis 146.

[0124] In the swivel arm 148, the locking magnets 166 are arranged within each of the locking magnet housings 168 of the swivel arm 148.

[0125] The rotary lock 102 generally has a fixing element 170 that holds the swivel arm 148 in the locked position (Figures 4C and 4D). In the illustrated exemplary embodiment, this fixing element 170 is in the form of a circumferential steel ring located within the housing 108, which also forms the base of the lock housing 156. A magnetic attraction (holding force) generally acts between the lock magnet 166 and the fixing element 170 that holds the swivel arm 148 in the locked position.

[0126] The key unit 104 corresponding to the rotary lock 102 has a body 180, within which a locking magnet 166 and a corresponding unlocking magnet 182 are provided. The positions and polar orientations of the locking magnet 166 and the corresponding unlocking magnet 182 are adapted such that when the key unit 104 is brought into contact with the circumferential contour 130 in a predetermined orientation by its inner contour 132, the unlocking magnet 182 exceeds the holding force between the locking magnet 166 and the fixed element 170, moving each of the swivel arms 148 from the locked position (Figures 4C and 4D) to the unlocked position (Figures 5A and 5C), thereby generating a magnetic force in each assigned locking magnet 166 that allows the lock core 110 to rotate within the housing 108, particularly from the closed position to the open position.

[0127] All rotation of the pivot arm 148 from the locked position (Figures 4C and 4D) to the unlocked position (Figures 5A and 5C) occurs only when the position and polarity of the unlock magnet 182 of the key unit 104 are matched to the lock magnet 166. In another key unit that does not have an unlock magnet 182 corresponding to at least one lock magnet 166, or in another key unit that has a corresponding unlock magnet with an improper position and / or polarity, the pivot arm 148 assigned to the lock magnet 166 is not moved to the unlocked position, thereby ensuring that the rotation of the lock core 110 within the housing 108 is prevented.

[0128] In this way, unauthorized rotation of the lock core 110, for example, from the closed position to the open position, can be reliably prevented, because rotation is only possible with the appropriate key unit.

[0129] If there are N swivel arms, then, in principle, with respect to the given position of the lock magnet 50, 2 N The combination of two types of rotary latches 102 and their corresponding key units. N Different pairs are possible, which preferably eliminates the two combinations in which the poles of the lock magnet 166 are oriented in the same direction (N pole facing in one direction, S pole facing in one direction) in order to prevent tampering, thereby 2 N - Two combinations remain.

[0130] To enable the safe use of the rotationally symmetrical combination, the circumferential contour 130 and the inner contour 128 are preferably formed asymmetrically so that the key unit 104 can only be positioned in a predetermined location on the rotary lock 102.

[0131] It has been proven that providing a pivot arm 148 having a specified lock element axis, which can be rotated as specified by magnetic interaction with a lock magnet 166 positioned at a distance from the lock element axis, results in extremely high reliability and a low failure rate. In particular, the specified rotational movement of the pivot arm 148 around the lock element axis due to the lever action of the lock magnet 166 can prevent the lock element 144 from tilting.

[0132] Figures 6A to 6C show a third exemplary embodiment of the rotary lock actuation device and a third exemplary embodiment of the system in various figures. System 206, comprising the rotary lock 202 and the key unit 204, has a similar structure and operating mode to system 106 in Figures 4A to 4D and 5A to 5C. Corresponding elements are denoted by the same reference numerals as in Figures 4A to 4D and 5A to 5C, even if these elements differ from one another in terms of their geometric configuration, and therefore, refer to the above description of these drawings.

[0133] Figure 6A shows a cross-sectional view of system 206, corresponding to the cross-sectional view of system 106 shown in Figure 4C. Figure 6B shows a cross-sectional view corresponding to the cross-sectional plane indicated as "VIb" in Figure 6A. Figure 6C shows the locking element in a perspective view.

[0134] Figures 7A to 7C also show a system 206 in which the key unit 204 is assembled to the rotary lock 202. Figure 7A shows a cross-sectional view having the same cross-sectional plane as in Figure 6A. Figure 7B shows a view of the key unit 204 from below. Figure 7C shows a cross-sectional view corresponding to the cross-sectional plane indicated as "VIIc" in Figure 7A.

[0135] The rotary lock 202 differs from the rotary lock 102 in that the locking element 224 has a different design. Like the locking element 144, the locking element 224 is positioned to surround the rotation axis 109 of the lock core 110 and has a swivel arm 248 which can be moved around each locking element axis 146 so that the locking element 224 engages with each of the blocking housings 156 of the housing 108 by a blocking section 154, thereby reliably preventing the rotation of the lock core 110, and so it can be moved between a locked position (Figures 6A and 6C) where the blocking section 154 disengages from the blocking housing 156, thereby allowing the rotation of the lock core 110.

[0136] In the swivel arm 248, the lock magnet 166 and the blocking section 154 are positioned on opposite sides of the swivel arm 248 with respect to their respective lock element axes 146.

[0137] Furthermore, the rotary lock 202 differs from the rotary lock 102 in terms of the different positioning and design of the fixing element 270, which is formed as a steel ring incorporated within the contour portion 128 in the rotary lock 202.

[0138] Furthermore, unlike the rotary lock 102, the rotary lock 202 has a contour portion 128 that is formed separately from the lock core 110. The contour portion 128 and the lock core 110 are connected to each other so as not to rotate relative to each other by a screw that extends from the end 134 of the lock core 110 through the lock core 110 to the contour portion 128 and is screwed into the contour portion 128.

[0139] In the rotary lock 102, it is advantageous that the fixing element 170 is arranged circumferentially within the housing 108, which means that the contour portion 128 can be made particularly flatter than in the rotary lock 202 in which the fixing element 270 is incorporated within the contour portion 128.

[0140] In the rotary lock 202, the spatial separation of the lock magnet 166 from the blocking section 154 is advantageous, as it allows the blocking section 154 to be designed to be more robust. [Explanation of symbols]
