Description

Technical Field

[0001] This invention relates to an operating device having a housing and an operating element, wherein the operating element is adjustable relative to the housing between a first operating element position and another operating element position, wherein a locking mechanism is provided for preventing unauthorized adjustment of the operating element from the first operating element position to the other operating element position, wherein the locking mechanism includes at least one locking element adjustable between a locked position (which is form-fitted to prevent adjustment of the operating element from the first operating element position to the other operating element position) and an unlocked position (which is released from adjustment of the operating element from the first operating element position to the other operating element position), and wherein the locking element includes at least one locking magnet for adjusting 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 invention also relates to a system having such an operating device and a corresponding key unit. Background Technology

[0002] A control device in the form of a swing lever is known from WO 2021 / 190908 A1, the swing lever being used to operate a closing device. This swing lever achieves a mechanically simple and fairly robust design, while also enabling simple operation and fairly secure access control.

[0003] However, depending on environmental conditions or violent damage, the locking mechanism may become stuck in such a control device. Summary of the Invention

[0004] In this context, the objective of the present invention is to provide an improved operating device that enables reliable locking or unlocking.

[0005] According to the invention, the above-mentioned task is achieved by an operating device having a housing and an operating element, wherein the operating element is adjustable relative to the housing between a first operating element position and another operating element position, wherein a locking mechanism is provided for preventing the operating element from being adjusted from the first operating element position to the other operating element position without authorization, wherein the locking mechanism includes at least one locking element adjustable between a locked position (which is form-fitted to prevent adjustment of the operating element from the first operating element position to the other operating element position) and an unlocked position (which is released from adjustment of the operating element from the first operating element position to the other operating element position), and wherein the locking element includes at least one locking magnet for adjusting 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, wherein the locking element includes a swing arm supported in a manner oscillating about the axis of the locking element, the swing arm being oscillating from the locked position to the unlocked position, and the locking magnet being arranged on the swing arm spaced apart from the axis of the locking element.

[0006] The locking element includes a swing arm that is pivotally supported, on which a locking magnet is arranged. Therefore, the locking element is specifically constructed by the swing arm and the locking magnet arranged thereon, providing a pivotable locking element with locking magnets. Alternatively, the locking element may include multiple locking magnets.

[0007] By providing a swing arm supported in a manner that allows it to swing about the axis of the locking element from a locked position to an 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 under adverse environmental influences or violent damage.

[0008] The locking magnets are arranged on the swing arm at intervals from the axis of the locking element. In particular, the center point of the locking magnet, or the central axis of the locking magnet that runs through the north and south poles of the locking magnet, is arranged at intervals from the axis of the locking element.

[0009] By means of a locking magnet arranged on the swing arm at a distance from the axis of the locking element, a lever action can be induced on the swing arm through magnetic interaction with the locking magnet, so that the swing arm can pivot selectively between the locked position and the unlocked position.

[0010] The locking magnet is preferably arranged at a distance from the axis of the locking element, such that the locking magnet is completely positioned outside the axis of the locking element. This results in a longer lever arm. However, it is also possible to extend the axis of the locking element through the lateral region of the locking magnet, while ensuring that the center point or central axis of the locking magnet is spaced from the axis of the locking element.

[0011] The swing arm is preferably made of a non-ferromagnetic material, especially aluminum or plastic, so as to minimize or eliminate the magnetic interaction between the locking magnet and the unlocking magnet of the corresponding key unit.

[0012] Furthermore, according to the present invention, the above-mentioned task is also achieved by a system having the above-mentioned operating device or its embodiment and having 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 operating device.

[0013] The key unit is preferably configured to pivot the at least one locking element to the unlock position by magnetic interaction between the at least one unlocking magnet and the at least one locking magnet when the key unit is abutted against the key abutment surface of the operating device.

[0014] The aforementioned operating device and system or their respective embodiments are preferably configured as part of an access control device (e.g., on a cover or door, particularly on a thin door such as a panel door), and / or for this purpose.

[0015] Different implementations of the control device and system are described below, wherein each implementation is applied independently to the control device and system. Furthermore, the various implementations can be arbitrarily combined with each other.

[0016] In one embodiment, the swing arm has a blocking section that, in a locked position, forms-fits to prevent the actuating element from adjusting from a first actuating element position to another actuating element position, and releases such adjustment in an unlocked position. The blocking section, for example, can engage in a receiving portion provided for this purpose in the housing in the locked position to prevent the actuating element from being adjusted to the other actuating element position.

[0017] The blocking section can be arranged on the same side of the swing arm as the locking magnet, relative to the axis of the locking element. Alternatively, the blocking section and the locking magnet can be arranged on different sides of the swing arm relative to the axis of the locking element. In this way, the blocking section can be arranged to be further spaced apart from the locking magnet, thereby allowing the blocking section to be constructed more robustly.

[0018] In one embodiment, the swing arm has a stop surface that abuts against a mating surface when the swing arm pivots to a locked or unlocked position. In this way, the locked or unlocked position can be defined as a defined end position of the swing arm. This allows for more reliable and uniform movement of the swing arm. The mating surface can be, for example, formed by a housing or by an actuating element.

[0019] Preferably, the swing arm has a first stop surface that abuts against a first mating surface when the swing arm pivots to the locked position, and a second stop surface that abuts against a second mating surface when the swing arm pivots to the unlocked position. The first mating surface may be formed, for example, by a housing, and the second mating surface may be formed by an actuating element, or vice versa.

[0020] In one embodiment, the locking mechanism includes at least two locking elements having corresponding pivotally supported swing arms and locking magnets disposed on the swing arms. In this way, security against unauthorized adjustment of the actuating element from one actuating element position to another can be improved. This is especially true when the locking mechanism includes at least four, preferably at least six, and particularly at least eight locking elements, and the locking elements have corresponding pivotally supported swing arms and locking magnets disposed on the swing arms. Regardless of the number of locking elements, it is preferable that the locking elements can be adjusted separately between locked and unlocked positions. Alternatively or additionally, if each locking element includes at least one locking magnet, the locking mechanism can have a simpler operating mode.

[0021] In one embodiment, the polarities of at least two of the locking magnets of different locking elements are different with respect to the direction from the locked position to the unlocked position of the respective locking element. This further enhances security against unauthorized adjustment of the operating elements. In particular, this method enables encryption, making it difficult for an unauthorized person to adjust all locking elements to their respective unlocked positions. Preferably, the polarities of at least two adjacent locking magnets can be different.

[0022] In one implementation, the pivoting directions from the locked position to the unlocked position of at least two different locking elements are different.

[0023] In some structural designs, this method allows for the installation of more locking elements within a predetermined structural space. Furthermore, it improves the vibration safety of the locking mechanism.

[0024] In one embodiment, the operating device is an operating device for operating the closing device, the operating element is an operating element for operating the closing device, a first operating element position is a stop position, and another operating element position is an operating position for operating the closing device. The operating device may in particular be a swing lever device.

[0025] Accordingly, the aforementioned task is achieved, in particular, by an operating device for manipulating a closing device, especially a swing lever device, having a housing and an operating element for manipulating the closing device, wherein the operating element is adjustable relative to the housing between a stop position and an operating position for manipulating the closing device, wherein a locking mechanism is provided for preventing the operating element from being adjusted from the stop position to the operating position without authorization, wherein the locking mechanism includes at least one locking element adjustable between a locked position (which is used to form-fittingly prevent the adjustment of the operating element from the stop position to the operating position) and an unlocked position (which is used to release the adjustment of the operating element from the stop position to the operating position), wherein the locking element includes at least one locking magnet for adjusting 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, and wherein the locking element includes a swing arm oscillatingly supported about the axis of the locking element, the swing arm being oscillating from the locked position to the unlocked position, and wherein the locking magnet is arranged on the swing arm spaced apart from the axis of the locking element.

[0026] It has been shown that the locking mechanism, which has one or more locking elements with corresponding swing arms, is particularly advantageously suited to provide an actuating element that can reliably lock and unlock in a stopped position. In particular, the actuating device of WO 2021 / 190908A1 can be improved in this way.

[0027] In one embodiment, the actuating element is configured as a swing lever, wherein the swing lever is pivotable relative to the housing about an actuating rotation axis in the actuated position. The swing lever is preferably connected to a rotatable actuating shaft that can be driven by the pivoting of the swing lever about the actuating rotation axis, for example, to actuate a closing device connected to the actuating shaft, such as a single-point or multi-point closing device.

[0028] In one embodiment, the housing has a recess in which the actuating element is received in a stopped position. In this way, the actuating element can be folded into the recess when not in use, thereby achieving a flatter structural form and reducing the risk of accidental snagging on the actuating element or the risk of damage. For this purpose, the actuating element can be adjusted from a first actuating element position to another actuating element position, and / or vice versa, by flipping about a flipping axis.

[0029] In one embodiment, the housing has a housing plane, a recess is embedded in the housing plane, and the actuating element has a flat upper side that, when the actuating element is received in the recess, is substantially parallel to, and preferably flush with, the housing plane. The upper side of the actuating element preferably has an angle of less than 5°, more preferably less than 2° relative to the housing plane. Additionally or alternatively, the upper side of the actuating element protrudes beyond the housing plane, preferably less than 10 mm, more preferably less than 5 mm. In this way, a particularly flat structure is possible.

[0030] In one embodiment, the housing has a stop, and the operating element has a stop receiving portion corresponding to the stop. In the stopped position of the operating element, the stop is received in the stop receiving portion, and a locking element engages in the recess of the stop in the locked position. In this way, a form-fitting obstruction is achieved below the operating element by the one or more locking elements, thereby making it difficult to operate the operating device.

[0031] In one embodiment, corresponding contours, particularly sliding surfaces, are provided on the swing arm and housing, especially on the stop. When the operating element is adjusted from another operating element position, particularly the operating position, to a first operating element position, particularly the stop position, these contours interact with each other such that the swing arm releases the adjustment of the operating element towards the first operating element position, particularly pivoting towards the unlock position. In this way, the operating element can be adjusted to the first operating element position, particularly the stop position, even when the key unit is removed, without the swing arm obstructing this adjustment. In the case of the swing lever device, in this way, for example, even without the key unit, the swing lever can be folded into the groove of the housing.

[0032] As corresponding profiles, for example, corresponding inclined sliding surfaces, or an inclined sliding surface and a corresponding edge, can be provided on the swing arm and on the housing (especially on the stop), which slide relative to each other when the actuating element is adjusted to the first actuating element position, and cause the swing arm to pivot in the direction of the unlock position, for example.

[0033] In one embodiment, the actuating element has a key support profile that is freely accessible in the stopped position, and at least one locking magnet is arranged to adjust the locking element from the locked position to the unlocked position when the corresponding key unit is abutted against the key support profile. In this way, it becomes difficult to operate the actuating device using geometrically mismatched key units. Furthermore, the key support profile makes it easier for the user to correctly position the key unit and therefore easier to operate the actuating device. Preferably, the key profile has the following asymmetry: the corresponding key unit can only be placed on the key support profile in one orientation.

[0034] In one embodiment, the locking mechanism includes at least two, if necessary at least four, preferably at least six, and particularly at least eight locking elements, with at least two of these locking elements arranged on opposite sides of the longitudinal axis of the actuating element and / or the longitudinal axis of the housing. In this way, the safety of preventing the actuating element from being forcibly adjusted from the stop position to the actuating position can be improved. This is especially true if at least two groups of locking elements (each comprising at least two, particularly 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.

[0035] In one embodiment, the locking mechanism comprises at least two, if necessary at least four, preferably at least six, and particularly at least eight locking elements, with at least two of these locking elements arranged spaced apart from each other along the longitudinal axis of the actuating element and / or along the longitudinal axis of the housing. In this way, the actuating element is form-fitted onto the housing at different points along its longitudinal axis in the stopped position. This also enhances security against the actuating element being forcibly moved from the stopped position to the actuating position. This is especially true if at least two locking elements of the locking element group are arranged spaced apart from each other along the longitudinal axis of the actuating element and / or the longitudinal axis of the housing.

[0036] Preferably, the spacing between adjacent locking elements is equal along the longitudinal axis of the operating element and / or the longitudinal axis of the housing. In this way, the manufacture of the operating device or key unit becomes easier.

[0037] In one embodiment, in the stopped position of the actuating element, the locking element is housed within the housing and / or actuating element in such a way that it is inaccessible from the outside. In this manner, the security against external damage to the locking mechanism can be further enhanced.

[0038] Alternatively or additionally, the at least one locking element may be housed in the housing and / or actuating element in the locked and / or unlocked positions such that the locking element is not visible from the outside when the actuating element is in the stopped position. In this way, security against unauthorized adjustment of the locking element from the locked to the unlocked position can be improved.

[0039] In contrast, it may be suitable that, in the stopped position of the actuating element, the locking element is partially housed in the housing and partially housed in the actuating element, and / or in the unlocked position, it is housed in either the housing or the actuating element.

[0040] In one embodiment, the locking element is housed in an unlocking receptacle of the actuating element or housing in the unlocked position, and more preferably, this is independent of the position of the actuating element. In this way, damage to the locking element when it is in the unlocked position can be prevented in a simple manner.

[0041] In one embodiment, in the stopped position of the operating element, the locking element is form-fitted into the locking receiver of the housing or the operating element in the locked position. In this way, the operating element can be prevented from being adjusted from the stopped position to the operating position in a structurally simple manner.

[0042] In one embodiment, the locking mechanism includes at least one safety element for automatically adjusting at least one locking element from the unlocked position to the locked position when the actuating element is adjusted to the stop position. In this way, it is possible to prevent the at least one locking element from being unintentionally held in the unlocked position when the actuating element is adjusted from another actuating element position (especially the actuating position) to the first actuating element position (especially the stop position).

[0043] The at least one locking element can be configured to automatically adjust the at least one locking element from the unlocked position to the locked position when the operating element is adjusted to a first operating element position (especially the stop position). In this way, when the operating element is adjusted to the first operating element position (especially the stop position), the locking element can be automatically adjusted from the unlocked position to the locked position by the locking element. Thus, security against unauthorized adjustment of the operating element from the first operating element position (especially the stop position) to another operating element position (especially the operating position) can be improved.

[0044] Alternatively or additionally, the at least one safety element may also be configured to retain the at least one locking element in a locked position when the actuating element is in a first actuating element position (especially the deactivated position). This may also contribute to improving security against unauthorized adjustment of the actuating element from the first actuating element position (especially the deactivated position) to another actuating element position (especially the actuated position).

[0045] In contrast, it may be suitable, for simplicity, to assign the at least one safety element to multiple locking elements when multiple locking elements exist. In this way, it is not necessary to provide a separate safety element for each locking element.

[0046] The safety element can be fixed to the actuating element. For ease of operation of the locking mechanism, the at least one safety element is preferably fixed to the housing. Alternatively or additionally, the at least one safety element can be at least partially, and in particular at least substantially, housed within the housing or actuating element. This ensures that the safety element is inaccessible from the outside, which improves security against damage to the locking mechanism (due to vandalism and unauthorized adjustment of the locking element from the locked to the unlocked position).

[0047] In one embodiment, the at least one locking element is made of a ferromagnetic material, and preferably, when the actuating element is adjusted to the first actuating element position (especially the stop position), the locking element can be automatically adjusted from the unlocked position to the locked position through the magnetic interaction between the locking magnet and the locking element. In this way, not only is a particularly simple structural design achieved, but also a reliable operation of the locking mechanism is realized.

[0048] For the same reason, alternatively or additionally, it may be advantageous that, in the first operating element position of the operating element, especially the stop position, the at least one locking element is held in the locked position by the magnetic interaction between the at least one locking magnet and the at least one safety element.

[0049] In principle, the automatic adjustment of the locking element and / or the retention of the locking element in the locked position are achieved, at least in part, through the magnetic interaction between the locking magnet and the safety element. However, for the reasons stated above, it is particularly preferred that the automatic adjustment of the locking element and / or the retention of the locking element in the locked position are achieved, at least substantially, through the magnetic interaction between the locking magnet and the safety element.

[0050] Here, ferromagnetic materials are specifically understood as materials that can be attracted by an external magnetic field. Therefore, the safety element can, in principle, be constructed as a permanent magnet. However, considering the simple and reliable operation of the locking mechanism, it is preferable that the safety element itself does not generate a magnetic field.

[0051] In one embodiment, the actuating device is a lock, particularly a rotary latch, such as a cam lock, and the actuating element is a lock cylinder rotatably supported in the housing. The lock cylinder is configured to engage a corresponding key unit in a torque-transmitting manner at a first end accessible from the front of the lock. The first actuating element position is a first rotational position of the lock cylinder in the housing, particularly an open or closed position, and the other actuating element position is a second rotational position of the lock cylinder in the housing, particularly a closed or open position.

[0052] Therefore, the aforementioned task is also achieved, in particular, by a lock, especially a rotary latch, such as a cam lock, having a closed housing and a lock cylinder rotatably supported within the closed housing, wherein the lock cylinder is configured to allow a key to be inserted in a torque-transmitting manner at a first end accessible from the front of the lock, wherein a locking mechanism is provided to prevent unauthorized rotation of the lock cylinder between the open and closed positions, wherein the locking mechanism includes at least one locking element capable of, in the closed position (which is used to form-fit the lock cylinder to prevent it from being in the closed position), The housing is adjusted between an open position (rotation between open and closed positions) and an unlocked position (which releases the rotation of the lock cylinder between open and closed positions), wherein the locking element includes at least one locking magnet for adjusting 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, and wherein the locking element includes a swing arm oscillating about the axis of the locking element, the swing arm being oscillating from the locked position to the unlocked position, and the locking magnet is arranged on the swing arm spaced apart from the axis of the locking element.

[0053] It has been shown that the locking mechanism (which has one or more locking elements with corresponding swing arms) is also particularly advantageously suited to provide a rotary latch with a lock cylinder rotation function that can reliably lock and unlock.

[0054] In one embodiment, the locking mechanism includes at least two, preferably at least three locking elements, each having a corresponding pivotally supported swing arm and a locking magnet disposed thereon, and these locking elements are preferably arranged around the rotation axis of the lock cylinder. In this way, the anti-manipulation security of the rotary latch is improved. Furthermore, this method allows for a larger number of swing arms with locking magnets, which, when combined, allow for a larger number of different rotary latch-key unit pairs.

[0055] In one embodiment, the lock cylinder has a profile at a first end, the profile having a circumferential profile defining the profile in the circumferential direction for inserting a corresponding key unit to transmit torque, and the profile is preferably constructed flat between the circumferential profiles. In this way, a particularly flat structural form is achieved, thereby particularly improving the robustness against tampering.

[0056] In one embodiment, a locking element is provided, configured to retain at least one locking element in a locked position through magnetic interaction, particularly between the locking element and the locking element, when the key unit is removed. In this way, vibration safety of the lock is improved, ensuring that the locking element is reliably held in the locked position even under mechanical vibration or shock, and thus preventing the lock from opening or closing when the key is removed. In the presence of multiple locking elements, the locking element is preferably configured to retain multiple locking elements in a locked position when the key is removed through magnetic interaction between the locking element and the locking element.

[0057] The magnetic interaction between the safety element and one or more locking elements is preferably a magnetic attraction interaction. However, it is also possible to consider a magnetic repulsion interaction between the safety element and one or more locking elements.

[0058] For example, the locking element may include a magnet, and the safety element may also be a magnet or made of ferromagnetic material, such as a ferromagnetic metal plate or metal ring, such as a steel plate or steel ring.

[0083] Figures 1a-1e A first embodiment of the manipulation device in the form of a swing lever and a first embodiment of the system are shown in different views. Figure 1a A perspective view of the swing lever device 2 and the key unit 4 is shown, which together constitute system 6. Figure 1b A top view is shown. Figure 1c It shows the corresponding in Figure 1b A sectional view of the cutting plane indicated by "Ic". Figure 1d A view of the key unit 4 from below is shown, in which some hidden elements are shown in dashed lines. Figure 1e It shows the corresponding in Figure 1c A sectional view of the cutting plane indicated by "Ie". Figure 1f The locking element is shown in a three-dimensional view.

[0084] The swing lever device 2 has a housing 10 and an operating element 12 in the form of a swing lever.

[0085] The swing lever 12 is capable of rotating about the swing lever axis 17 relative to the housing 10, in the stop position ( Figures 1a-1e ) and manipulation position ( Figures 2a-2c The two are regulated.

[0086] Figures 2a-2c A system 6 with a swing lever device 2 and a key unit 4 is shown, wherein the swing lever 12 is in the operating position. Figure 2a A 3D view is shown. Figure 2bIt shows that it has the corresponding Figure 1c A sectional view of the cutting plane. Figure 2c It shows the corresponding in Figure 2b A sectional view of the section plane indicated by "IIc".

[0087] In the operating position, the swing lever 12 can pivot about the operating rotation axis 13, thereby transmitting rotational motion to the operating shaft 16. The swing lever 12 is connected or can be connected to the closing device 14, such as a single-point or multi-point closing device of an access device (like a door or cover), via the operating shaft. In this way, the closing device 14 can be operated by pivoting the swing lever 12 about the operating axis 13. Figure 3 The pivot position (operation position) of the swing lever 12 is illustrated in a three-dimensional diagram.

[0088] In the stop position ( Figures 1a-1e In this housing 10, the swing lever 12 is housed in a recess 18. This prevents the swing lever 12 from being accidentally manipulated. Furthermore, this allows for a flat structural form, thereby preventing accidental hooking onto the protruding swing lever 12, for example.

[0089] In the swing lever device 2, the flat structure is also achieved in particular by the fact that the swing lever 12 has a flat upper side 20, which is parallel to the housing plane 21 when the swing lever 12 is received in the groove 18.

[0090] The swing lever 12 also prevents unauthorized movement from the stop position ( Figures 1a-1e ) was adjusted to the operating position ( Figures 2a-2c Therefore, the swing lever device 2 has a locking mechanism 22, which prevents the swing lever device 2 from being moved from the stop position to the operating position without the key unit 4.

[0091] The locking mechanism 22 includes a plurality of locking elements 24, which in this embodiment are eight locking elements, and these locking elements can be respectively in the locked position ( Figure 1e ) and unlock location ( Figure 2c The locking elements 24 are adjusted between the locked position and the operating position. In the locked position, these locking elements 24 are shape-fitted to prevent the swing lever 12 from adjusting from the stop position to the operating position, and in the unlocked position, these locking elements 24 release the swing lever 12 from the stop position to the operating position.

[0092] For this purpose, each locking element 24 has a swing arm 28 supported around the locking element axis 26, which can swing from the locked position to the unlocked position. In this embodiment, these swing arms 28 have lateral support shafts 30, which support the swing arms in corresponding support receptacles 32 in the swing lever 12.

[0093] Furthermore, the swing arm 28 has a blocking section 34, which engages with the locking portion 36 of the housing 10 in the locked position of the corresponding swing arm 28. In this embodiment, the locking portion is formed by two opposing recesses 38 of the stop 40 protruding in the groove 18.

[0094] The swing arm 28 also has a first stop surface 42 and a second stop surface 44, wherein the first stop surface 42 stops on the mating surface 46 of the swing lever 12 when it reaches the locked position, thereby defining the locked position, and wherein the second stop surface 44 stops on the mating surface 48 of the swing lever 12 when it reaches the unlocked position, thereby defining the unlocked position. The swinging motion of each swing arm 28 is restricted by the stop surfaces 42, 44 and the corresponding mating surfaces 46, 48, thereby ensuring a reliable and repeatable alternation between the locked and unlocked positions. In this example, the first and second mating surfaces 46, 48 are identical. However, the first and second mating surfaces can also be different surfaces.

[0095] Each locking element 24 has a corresponding locking magnet 50 arranged on its swing arm 28. More precisely, the locking magnet is arranged at a distance from the axis 26 of the corresponding locking element, such that the magnetic force acting on the locking magnet 50 can cause the swing arm 28 to pivot between the locked position and the unlocked position through a lever between the positions of the locking magnet 50 and the axis 26 of the locking element.

[0096] In the swing arm 28, these locking magnets 50 are arranged in the corresponding locking magnet receiving portion 51 of the swing arm 28.

[0097] The swing lever device 2 has a safety element 52, which in principle keeps the swing arm 28 in the stopped position. Figure 1e In this embodiment, the safety element 52 is constructed in the form of a steel element arranged in the stop 40. A magnetic attraction acts between the locking magnet 50 and the steel element 52, which in principle holds the swing arm 28 in the stop position (holding force).

[0098] The swing lever 12 has a stop receiving portion 54 on its lower side, which matches the stop 40 such that the stop 40 is arranged in the stop receiving portion 54 in the stopped position. In this way, the swing arms 28 can be arranged on both sides of the stop 40 and embedded in the opposite recesses 38 of the stop 40 on both sides. In this way, a greater number of swing arms can be used in a given structural space. In addition, higher vibration safety can be achieved by the locking of the shape fit on both sides. Furthermore, higher anti-manipulation safety can be achieved by the locking of the shape fit relative to the center of the swing lever 12.

[0099] Furthermore, these swing arms 28 are arranged such that one or more of the swing arms 28 have a rotational direction opposite to that of the other swing arms, from the locked position to the unlocked position. Preferably, as Figure 1e As shown, swing arms 28 with opposite rotation directions are provided on each side of the stop 40. This arrangement further improves anti-manipulation safety and / or vibration safety. Furthermore, this arrangement allows for the installation of a greater number of swing arms 28 within a given space.

[0100] The swing lever 12 has a key support profile 56 on its upper side, which matches the key profile 58 corresponding to the lower side of the key unit 4 of the swing lever device 2. The key support profile 56 specifically has recesses 60, for example two opposing recesses, the shapes of which match the corresponding protrusions 62 of the key profile 58, and / or vice versa. In this way, correct orientation of the key profile 58 relative to the key support profile 56 becomes easy.

[0101] The key support profile 56 and key profile 58, especially the recess 60 and protrusion 62, are preferably matched such that the key profile 58 and key support profile 56 mate only in exactly one orientation of the key unit 4 and the swing lever device 2. In this embodiment, the recess 60 and protrusion 62 have, for example, corresponding bevels 64 and 66, which make contact only when the key profile 58 and key support profile 56 are in a predetermined orientation.

[0102] The key unit 4 corresponding to the swing lever device 2 has a main body 70, in which an unlocking magnet 72 corresponding to the locking magnet 50 is provided. The corresponding positions and polarities of the locking magnet 50 and the corresponding unlocking magnet 72 are matched such that when the key unit 4 is abutted against the key support profile 56 with the key profile 58 in a predetermined orientation, the unlocking magnet 72 induces a magnetic force on the respective locking magnet 50. This magnetic force overcomes the holding force between the locking magnet 50 and the safety element 52, and causes the corresponding swing arm 28 to move from the locked position (…). Figure 1e Pivot to the unlock position ( Figure 2cIn this position, the swing lever 12 can move from the stop position ( Figure 1a Pivot to the operating position ( Figure 2a ). In the unlock location ( Figure 2c In this configuration, the swing arm 28 is preferably fully pulled back into the unlocking receiving portion 74 of the swing lever 12, and therefore does not protrude laterally beyond the swing lever 12 into the stop receiving portion 54. In this way, damage to the swing arm 28 can be prevented when it is flipped open to the operating position or when it is flipped into the stop position.

[0103] All swing arms 28 will only move from the locked position when the unlocking magnet 72 of the key unit is matched with the locking magnet 50 in both position and polarity. Figure 1e Pivot to the unlock position ( Figure 2c If another key unit is used for at least one of the locking magnets 50 that does not have a corresponding unlocking magnet 72, or whose corresponding unlocking magnet has the wrong position and / or polarity, then the swing arm 28 belonging to the locking magnet 50 in question will not move to the unlock position, thereby shape-fittingly preventing the swing lever 12 from adjusting from the stop position to the operating position.

[0104] In this way, it is possible to reliably prevent unauthorized adjustment of the swing lever 12 from the stop position to the operating position, as this can only be achieved by means of a matching key unit.

[0105] polar direction Figures 1d-1f and Figure 2b Different shaded lines are used to indicate the magnetic poles, as is the case in the accompanying drawings of other embodiments. The magnetic north pole is indicated by a dotted shaded line, and the magnetic south pole is indicated by a cross-shaped shaded line.

[0106] In principle, using N swing arms (assuming the locking magnet is positioned at 50) can be considered as 2 N There are 2 combinations, meaning 2 can be considered. N Pairs of different swing lever devices 2 and corresponding key units, wherein, preferably, to ensure anti-manipulation security, two combinations of locking magnets 50 with the same polar orientation (north poles in one direction and south poles in one direction) are preferred, thus retaining 2 N -2 combinations.

[0107] In system 6, the 180° rotationally symmetrical combination is prohibited by key support profile 56 and key profile 58. When the key unit 4 is rotated 180° and supported, the key support profile 56 and key profile 58 partially protrude from each other by ramps 64 and 66, thereby the magnetic force of the unlocking magnet 72 is no longer partially sufficient to overcome the holding force of the locking magnet 50, so that the swing lever 12 (which has a theoretically matched combination of unlocking magnets when the key unit is rotated 180° and supported) is locked and held in the stop position.

[0108] Setting a defined locking element axis for the swing arm 28 has proven to be highly reliable and interference-free. The swing arm can pivot in a defined manner through magnetic interaction with the locking magnet 50 spaced apart from the locking element axis. In particular, the defined swinging motion of the swing arm 28 about the locking element axis by the leverage force of the locking magnet 50 can prevent the locking element 24 from tilting.

[0109] In order to flip the swing lever 12 into the stop position without damaging the swing arm 28 when the key unit is removed, the swing arm 28 and the locking element 40 have corresponding profiles 76, 78 in the form of sliding surfaces. During the process of adjusting the swing lever 12 to the stop position (at which time, for example, the swing arm 28 is in the locked position), these profiles slide against each other, causing the swing arm 28 to pivot in the direction of the unlock position and release the adjustment of the swing lever 12 to the stop position.

[0110] Figures 4a-4f A second embodiment of the operating device is shown in different views, specifically in the form of a rotary lock, and a second embodiment of the system is also shown. Figure 4a A perspective view of the rotary lock 102 and the key unit 104 is shown, which together constitute system 106. Figure 4b A top view is shown. Figure 4c It shows the corresponding in Figure 4b A sectional view of the section plane indicated by "IVc". Figure 4d It shows the corresponding in Figure 4c A sectional view of the section plane indicated by "IVd". Figure 4e It shows the corresponding in Figure 4c A sectional view of the cutting plane indicated by "IVe". Figure 4f The locking element is shown in a three-dimensional view.

[0111] Figures 5a-5c A system 106 with a rotary lock 102 and a key unit 104 is shown, wherein the key unit 104 is placed on the rotary lock 102. Figure 5a It shows that it has the corresponding Figure 4c A sectional view of the cutting plane. Figure 5bA view of the key unit 104 from below is shown. Figure 5c It shows the corresponding in Figure 5a A sectional view of the cutting plane indicated by "Vc".

[0112] The rotary lock 102 has a housing 108 and an operating element 110, which is in the form of a lock cylinder that is rotatably supported in the housing 108 about a rotation axis 109.

[0113] The housing 108 has a cylindrical section 112 through which the housing can be guided through a recess 114 (e.g., a hole) in a thin wall 116 (e.g., a panel door), such that the housing abuts against the wall 116 with an abutment flange 118. The rotary lock 102 can be secured to the wall 116 by tightening the lock nut 120 onto the external thread 122 provided on the cylindrical section 112.

[0114] The lock cylinder 110 is configured at a first end 126 accessible from the front side 124 of the rotary lock 102 for inserting the key unit 104 in a torque-transmitting manner. In this embodiment, the lock cylinder 110 has a profile 128 having circumferential profiles 130 defining the profile 128 in the circumferential direction, the profile 128 being configured to be flat between the circumferential profiles 130. The key unit 104 has an inner profile 132 corresponding to the circumferential profiles 130. The circumferential profiles 130 and the inner profiles 132 are configured for coupling in a torque-transmitting manner, in this embodiment, by means of asymmetrical profiles.

[0115] This profile 128 allows for a very flat structure on the front side 124. This improves safety by preventing snagging on the protrusions and also provides greater protection against damage due to the smaller engagement surface of the protrusions.

[0116] At end 134, opposite to the first end 126, the lock cylinder 110 can drive the locking mechanism. In this embodiment, the rotary lock 102 is configured as a cam lock, and accordingly, the rotary tongue 136 is torsionally connected to the lock cylinder 110.

[0117] To prevent the lock cylinder 110 from rotating unauthorizedly between a closed position (in which, for example, the rotating tongue 136 engages from the rear with the mating surface of the frame surrounding the wall 116, and prevents the wall 116 from opening) and an open position (in which, the rotating tongue 136 disengages from the mating surface, and releases the wall 116 from opening), a locking mechanism 142 is provided to prevent the lock cylinder 110 from rotating unauthorizedly.

[0118] The locking mechanism 142 includes a plurality of locking elements 144, which in this embodiment are eight locking elements 144, and these locking elements are positioned around the rotation axis 109 of the lock cylinder 110. These locking elements 144 can be in the locked position (…). Figure 4c and Figure 4d ) and unlock location ( Figure 5a and Figure 5c The locking elements 144 pivot between the locking elements 144 in the locked position, where they are shaped to prevent rotation of the lock cylinder 110, and in the unlocked position, they release rotation of the lock cylinder 110.

[0119] Each locking element 144 has a swing arm 148 supported around the locking element axis 146, which can swing from the locked position to the unlocked position. In this embodiment, the swing arm 148 has a lateral support shaft 150, which supports the swing arm 148 in a corresponding support receiving portion 152 on the lock cylinder 110.

[0120] In addition, the swing arm 148 has blocking sections 154, which engage with the corresponding locking receptacles 156 of the housing 108 in the locked position of the respective swing arm 148.

[0121] Furthermore, the swing arm 148 also has a first stop surface 158 and a second stop surface 160. When the first stop surface 158 reaches the locked position, it stops on the mating surface 162 of the lock cylinder 110, thereby defining the locked position. And when the second stop surface 160 reaches the unlocked position, it stops on the mating surface 164 of the lock cylinder 110, thereby defining the unlocked position. The stop surfaces 158 and 160 and their corresponding mating surfaces 162 and 164 restrict the swinging movement of each swing arm 148, thereby ensuring a reliable and repeatable alternation between the locked and unlocked positions.

[0122] Furthermore, each locking element 144 has a corresponding locking magnet 166 arranged on its swing arm 148. More precisely, the locking magnet is spaced apart from the axis 146 of the corresponding locking element, such that the magnetic force acting on the locking magnet 166 can cause the swing arm 148 to pivot between the locked position and the unlocked position through a lever between the positions of the locking magnet 166 and the axis 146 of the locking element.

[0123] In the swing arm 148, these locking magnets 166 are arranged in the corresponding locking magnet receptacle 168 of the swing arm 148.

[0124] Rotary lock 102 has a safety element 170 that, in principle, holds the swing arm 148 in the stopped position. Figures 4c-4dIn this embodiment, the safety element 170 is constructed as a surrounding steel ring arranged in the housing 108, which also forms the base of the locking receiver 156. A magnetic attraction acts between the locking magnet 166 and the safety element 170, which in principle holds the swing arm 148 in the stopped position (holding force).

[0125] The key unit 104 corresponding to the rotary lock 102 has a body 180, in which an unlocking magnet 182 corresponding to the locking magnet 166 is provided. The corresponding positions and polarities of the locking magnet 166 and the corresponding unlocking magnet 182 are matched such that when the key unit 104 is abutted against the circumferential contour 130 in a predetermined orientation within its inner contour 132, the unlocking magnet 182 induces a magnetic force on the respective locking magnet 166. This magnetic force overcomes the holding force between the locking magnet 166 and the locking element 170, and causes the corresponding swing arm 148 to move from the locked position (…). Figures 4c-4d Pivot to the unlock position ( Figure 5a and Figure 5c This allows the lock cylinder 110 to be twisted within the housing 108, particularly from the closed position to the open position.

[0126] All swing arms 148 will only move from the locked position when the unlocking magnet 182 of the key unit 104 is matched with the locking magnet 166 in both position and polarity. Figures 4c-4d Pivot to the unlock position ( Figure 5a and Figure 5c If another key unit is used for at least one of the locking magnets 166 that does not have a corresponding unlocking magnet 182, or whose corresponding unlocking magnet has the wrong position and / or polarity, then the swing arm 148 belonging to the locking magnet 166 in question will not move to the unlock position, thereby shape-fittingly preventing the lock cylinder 110 from rotating in the housing 108.

[0127] In this way, unauthorized rotation of the lock cylinder 110, such as from the closed position to the open position, can be reliably prevented, as this can only be achieved using a matching key unit.

[0128] In principle, using N swing arms (with the locking magnet at a predetermined position 50), it is possible to consider 2 N There are 2 combinations, meaning we can consider 2. N Pairs of different rotary locks 102 and corresponding key units, wherein, preferably, to ensure anti-manipulation security, two combinations of locking magnets 166 with the same polar orientation (north poles in one direction and south poles in one direction) are preferred, thus retaining 2 N -2 combinations.

[0129] In order to reliably use the combination that is rotationally symmetrical to each other, the circumferential profile 130 and the inner profile 128 are preferably constructed asymmetrically in such a way that the key unit 104 can only be placed on the rotary lock 102 in a predetermined position.

[0130] Providing a defined locking element axis for the swing arm 148 has proven to be highly reliable and less disruptive. The swing arm can be pivoted in a defined manner through magnetic interaction with a locking magnet 166 spaced apart from the locking element axis. In particular, the defined swinging motion of the swing arm 148 about the locking element axis via the leverage force of the locking magnet 166 prevents the locking element 144 from tilting.

[0131] Figures 6a-6c A third embodiment of the operating device, in the form of a rotary lock, is shown in different views. A third embodiment of the system is also shown. System 206, having a rotary lock 202 and a key unit 204, is also shown. Figures 4a-4d and Figures 5a-5c Compared to system 106, it has a similar structure and a similar way of working. The corresponding components, even though they may differ partially from each other in their geometry, use the same... Figures 4a-4d and Figures 5a-5c The same reference numerals are used in the accompanying drawings, and for this purpose, reference is made to the above description of these drawings.

[0132] Figure 6a A cross-sectional view of system 206 is shown, which corresponds to Figure 4c A sectional view of system 106. Figure 6b It shows the corresponding in Figure 6a A sectional view of the section plane indicated by "VIb". Figure 6c The locking element is shown in a three-dimensional view.

[0133] also, Figures 7a-7c The system 206 is shown, which has a key unit 204 placed on a rotary lock 202. Figure 7a It shows that it has the corresponding Figure 6a A sectional view of the cutting plane. Figure 7b A view of the key unit 204 from below is shown. Figure 7c It shows the corresponding in Figure 7a A sectional view of the section plane indicated by "VIIc".

[0134] The difference between rotary lock 202 and rotary lock 102 lies in the configuration of the locking element 224. Similar to locking element 144, locking element 224 is arranged around the rotation axis 109 of lock cylinder 110 and has swing arms 248, which can be positioned in the locked position around the corresponding locking element axis 146. Figure 6a and Figure 6c) and unlock location ( Figure 7a and Figure 7c The locking element 224 pivots between the locking elements in the locked position, where the locking element 224 engages with the corresponding locking receptacle 156 of the housing 108 with the blocking section 154, and in this form fit prevents the rotation of the lock cylinder 110. In the unlocked position, the blocking section 154 disengages from the locking receptacle 156, and in this way releases the rotation of the lock cylinder 110.

[0135] In the swing arm 248, the locking magnet 166 and the blocking section 154 are arranged on different sides of the swing arm 248 relative to the corresponding locking element axis 146.

[0136] Furthermore, the difference between rotary lock 202 and rotary lock 102 lies in the configuration and positioning of the safety element 270, which is constructed as a steel ring integrated into the profile 128 in rotary lock 202.

[0137] Furthermore, the rotary lock 202 differs from the rotary lock 102 in that the profile 128 and the lock cylinder 110 are constructed separately. The profile 128 and the lock cylinder 110 are connected to each other in a torsion-resistant manner by means of a screw that passes through the lock cylinder 110 from the end 134 of the lock cylinder 110 to the profile 128 and is screwed into the profile.

[0138] In the case of the rotary lock 102, it is advantageous that the safety element 170 is arranged in the housing 108 in the circumferential direction, thereby, in particular, the profile 128 can be constructed to be flatter than the rotary lock 202 in which the safety element 270 is integrated into the profile 128.

[0139] In the case of the rotary lock 202, it is advantageous that the locking magnet 166 and the blocking section 154 are spatially separated, thereby allowing the blocking section 154 to be constructed more robustly.
