Description

[0001] Swing lever for operating a locking device of an access control device and swing lever system

[0002] The invention relates to a pivot lever for actuating a locking device, in particular a bolt lock and / or bar lock, of an access control device, in particular a door and / or flap, with a base part for fastening the pivot lever, in particular to the access control device, and an actuating lever for actuating the locking device,The actuating lever is pivotable relative to the base part between a locking position for locking the actuating lever to the base part and an actuating position for actuating the locking device and / or when the locking device is actuated. At least one locking element is provided to secure the actuating lever against unauthorized pivoting from the locking position into the actuating position, adjustable between a locking position that positively blocks the pivoting of the actuating lever and a release position that allows the pivoting of the actuating lever. Furthermore, the invention relates to a pivot lever system comprising at least one such pivot lever and a key that fits the pivot lever.

[0003] Access control devices with which access points can be closed and opened are known in various designs, for example in the form of doors or flaps. Regardless of their design, access control devices often have at least one locking device to prevent the access control device from inadvertently moving from a position closing access to a position opening access and / or from being adjusted accordingly by unauthorized persons. Latch locks, for example, are known as locking devices. Latch locks typically have at least one latch that can be adjusted between a position for positively blocking the opening of the access control device and a position for enabling the opening of the access control device.Latch locks, in which the latch can be pivoted and / or rotated, are often also referred to as rotary latch locks. In addition to latch locks, so-called bar locks are also known, which typically have at least one bar element. The at least one bar element allows the access control device to be secured at two or more spaced-apart, for example, opposite, points, for example, on a frame. This can increase security against unauthorized opening of the access control device.

[0004] Regardless of the design of the locking device, pivot levers are often used to actuate the locking device. Pivoting levers typically comprise a base part, with which the pivot lever can be attached to the access control device, and an actuating lever that serves to actuate the locking device. The actuating lever can usually be pivoted relative to the base part between a locking position, in which the actuating lever can be locked to the base part, and an actuating position, in which the locking device can be actuated with the actuating lever. Pivoting levers offer the advantage that a high torque can be introduced into the locking device with little effort.

[0005] To secure the operating lever against unauthorized pivoting, for example by unauthorized persons, from the locked position to the actuated position, pivot levers often have at least one locking element. The at least one locking element is typically adjustable between a locking position, in which the locking element positively blocks pivoting of the operating lever from the locked position to the actuated position, and a release position, in which the locking element allows pivoting of the operating lever from the locked position to the actuated position. A key fitting the pivot lever is typically provided for adjusting the at least one locking element from the locked position to the release position.

[0006] Such a pivot lever and such a pivot lever system are known from DE 10 2020 108484 A1. The at least one locking element is designed as a locking magnet, and the key has at least one key magnet, so that the locking magnet can be moved from the locking position to the release position by magnetic interaction with the key magnet. This has the advantage that, when the actuating lever is closed, the at least one locking magnet does not have to be accessible from the outside in order to be moved from the locking position to the release position. This allows the locking mechanism to be better protected against external contamination and damage, for example, due to vandalism. However, there is still a need for a pivot lever with improved properties.

[0007] Therefore, the object of the present invention is to design and further develop the pivot lever and the pivot lever system of the type mentioned at the outset and described in more detail above in such a way that the properties of the pivot lever can be improved while providing a high level of protection against external contamination and damage.

[0008] This object is achieved in a pivot lever according to the preamble of claim 1 in that the at least one locking element is adjustable from the locking position to the release position by adjusting at least one adjusting magnet from a basic position to an unlocking position, that the at least one adjusting magnet is adjustable from the basic position to the unlocking position by a magnetic interaction with at least one key magnet of a key matching the pivot lever, and that the at least one locking element and the at least one adjusting magnet are formed from different materials.

[0009] The stated object is further achieved according to claim 16 by a pivot lever system with at least one pivot lever according to one of claims 1 to 15 and a key matching the pivot lever comprising at least one key magnet for adjusting the at least one adjusting magnet of the pivot lever from the basic position into the unlocking position.

[0010] According to the invention, the pivot lever has at least one adjusting magnet that can be adjusted from a home position to an unlocked position. By adjusting the at least one adjusting magnet from the home position to the unlocked position, the at least one locking element can be adjusted from the locked position to the release position. The at least one adjusting magnet can, in turn, be adjusted from the home position to the unlocked position by magnetic interaction with at least one key magnet of a key that fits the pivot lever.The magnetic interaction between the at least one adjusting magnet and the at least one key magnet can therefore cause the adjusting magnet to be adjusted from the basic position to the unlocked position, which in turn can cause the at least one locking element to be adjusted from the locked position to the released position. This enables a high level of protection against contamination and damage from the outside, since in the locked position of the actuating lever, neither the adjusting magnet nor the locking element needs to be accessible from the outside in order to adjust the locking element from the locked position to the released position. Rather, the at least one adjusting magnet and / or the at least one locking element can be inaccessible from the outside in the locked position of the actuating lever.Secondly, it is possible for the at least one locking element to be made of a different material than the at least one adjusting magnet. This allows the materials and thus the material properties of the locking element and the adjusting magnet to be adapted independently of one another to the respective intended use, ultimately improving the properties of the pivot lever. In particular, the at least one locking element can be optimized with regard to its mechanical properties, and the at least one adjusting magnet can be optimized with regard to its magnetic properties.

[0011] To avoid impairing the functionality of the at least one adjusting magnet, the base part, the actuating lever, and / or a base body of the key can be made of a non-ferromagnetic material. Aluminum and / or zinc are particularly suitable materials for this purpose. Regardless of the material, the base part, the actuating lever, and / or a base body of the key can be manufactured particularly cost-effectively by die-casting.

[0012] The base part, which can be constructed in one or more parts, is intended in particular for attaching the pivot lever to the access control device. However, it is also conceivable to attach the pivot lever to a component other than the access control device using the base part, for example, to a frame supporting the access control device, such as a cabinet. Irrespective of this, the operating lever can expediently be pivotably mounted on the base part.

[0013] The actuating lever can be provided such that the locking device is actuated when the actuating lever is in the actuating position. The actuating device can then be actuated by pivoting the actuating lever from the locking position into the actuating position. However, it is preferred if the actuating lever is pivotable about a locking axis between the locking position and the actuating position, and in the actuating position, is pivotable about an actuating axis inclined to the locking axis, in particular at least substantially perpendicular, to actuate the locking device.

[0014] Regardless of the design of the actuating position, it may be advisable for the actuating lever to be at least partially, in particular at least substantially, accommodated in a lever receptacle of the base part in the locked position. This can not only contribute to a flat design of the pivoting lever, but also to good protection of the locking mechanism against external influences. The lever receptacle can expediently be designed as a recess. Fundamentally independent of whether the actuating lever is accommodated in a lever receptacle, it may be advisable for pivoting of the actuating lever about the actuating axis to be positively blocked in the locked position of the actuating lever.

[0015] The magnetic interaction between the at least one adjusting magnet and the key magnet, in particular the one associated with the adjusting magnet, can be, for example, a magnetically attractive interaction. However, functionally, it is preferred if it is a magnetically repulsive interaction. Irrespective of this, in a use position of the key, the adjusting magnet can expediently be adjusted to the unlocked position by the magnetic interaction between the at least one adjusting magnet and the key magnet, in particular the one associated with the adjusting magnet.

[0016] The pivot lever and / or pivot lever system may, if necessary, include the locking device and / or the access control device. However, this is not mandatory.

[0017] For the sake of clarity and to avoid unnecessary repetition, the pivot lever and the pivot lever system are described jointly below, without distinguishing between the pivot lever and the pivot lever system. However, the skilled person will be able to determine from the context which feature is particularly preferred with regard to the pivot lever and / or the pivot lever system.

[0018] In a first particularly preferred embodiment of the pivot lever, the pivot lever has at least two locking elements. In this way, security against forced displacement of the pivot lever from the locked position can be increased. For the same reason, it may be even more advantageous if the pivot lever has at least three, if necessary at least four, preferably at least six, particularly preferably at least eight locking elements. Regardless of the specific number, the locking elements can then expediently each be adjustable between a locking position that positively blocks the pivoting of the actuating lever and a release position that allows the actuating lever to pivot.With regard to a high level of security against unauthorized unlocking of the operating lever, it may further be advisable for the pivot lever to have a number of adjusting magnets corresponding to the number of locking elements, each of which is assigned to one of the locking elements. The locking elements can then expediently each be adjustable from the locking position to the release position by adjusting the assigned adjusting magnet from a home position to an unlocking position, wherein the adjusting magnets can each be adjusted from the home position to the unlocking position by magnetic interaction with a key magnet of the key. It can further be provided that the pole orientations of at least two of the adjusting magnets differ with respect to the respective unlocking direction.In this way, a type of coding can be implemented, which can contribute to increased security against unauthorized unlocking. This is especially true if the pole orientations of at least two adjacent adjusting magnets differ with respect to the respective unlocking direction. Regardless of this, the unlocking direction generally refers to the direction in which the adjusting magnet can be adjusted from the home position to the unlocking position.

[0019] Regardless of the number of locking elements and adjustment magnets, a flat design of the pivot lever can be achieved if the pivot lever comprises at least one lateral locking element for positively blocking the pivoting of the actuating lever on a longitudinal side of the actuating lever. The at least one lateral locking element can then positively block the pivoting of the actuating lever from the locking position into the actuating position on a longitudinal side of the actuating lever in the locking position. Irrespective of this, it can be advantageous, with regard to high security against forcible adjustment of the actuating lever, if the pivot lever comprises at least two, preferably at least four, in particular at least six, and particularly preferably at least eight, lateral locking elements.For the same reason, it may be particularly appropriate for the lateral locking elements to be designed to positively block the pivoting of the actuating lever on opposite longitudinal sides of the actuating lever. Irrespective of this, the at least one lateral locking element can be simply and expediently designed in a pin-shaped manner.

[0020] Alternatively or in addition to a lateral locking element, it may be advisable to provide a high level of security against unauthorized adjustment of the actuating lever from the locked position if the pivoting lever has at least one rear locking element for positively blocking the pivoting of the actuating lever on a rear side of the actuating lever assigned to the base part. The rear locking element can then positively block the pivoting of the actuating lever from the locked position into the actuating position on the rear side of the actuating lever assigned to the base part in the locked position. With regard to simple and cost-effective production and flexible use of the pivoting lever, it may be advisable for the at least one adjusting magnet to be made of a permanent magnetic material.

[0021] Permanent magnets, for example, unlike electromagnets, can permanently generate a magnetic field, in particular one that is at least substantially constant, without the need for external energy. Irrespective of this, neodymium iron boron (Nd2Fel4B) can be used as a permanent magnetic material, enabling a high magnetic field strength at moderate cost. Alternatively or in addition to a permanent magnetic design of the adjusting magnet, the at least one locking element can preferably be made of a non-permanent magnetic material. Materials that are not permanently magnetic can be suitable for the locking element, for example, due to their mechanical and / or manufacturing properties.

[0022] From a functional point of view, it may be appropriate for the at least one locking element to be formed from a ferromagnetic material. The locking element can then be adjustable through a magnetic interaction with the adjustment magnet, in particular the one assigned to the locking element. Irrespective of this, a ferromagnetic material may be suitable, particularly for the at least one lateral locking element. As an alternative to a ferromagnetic design, the locking element may be formed from a non-ferromagnetic material. This may be particularly advantageous from a manufacturing point of view, particularly when the locking element has a complex geometry, which can be particularly advantageous for the rear locking element.

[0023] With regard to secure locking of the actuating lever against forcible adjustment from the locked position, it can be advantageous if the material of the at least one locking element has a higher shear strength than the material of the adjusting magnet, in particular the one assigned to the locking element. This can increase the security against breakage of the locking element, which is typically subject to high shear forces when the actuating lever is forcibly adjusted from the locked position. Against the same background, it can be appropriate, for example, if the shear strength of the material of the at least one locking element is at least 1.2 times, if necessary at least 1.5 times, preferably at least twice, in particular at least three times, particularly preferably at least four times, as high as the shear strength of the material of the adjusting magnet.Regardless of a corresponding ratio, the shear strength of the material of the at least one locking element can be, for example, at least 50 N / mm. 2 , preferably at least 100 N / mm 2 , in particular at least 150 N / mm 2 , amount to.

[0024] Regardless of the shear strength, the locking element can be manufactured by die casting. Die casting enables economical production even of complex geometries, which can be particularly useful for the rear locking element. Alternatively or in addition to production by die casting, the at least one locking element can be formed from a metallic material. Metallic materials are particularly suitable for the locking element in terms of their properties. This is even more true for steel materials, particularly due to their mechanical properties. A steel material can be particularly suitable for the at least one lateral locking element. Irrespective of this, ferritic steel materials can be particularly preferred from a functional perspective, as they are typically highly magnetic. To alternatively or additionally prevent corrosion, galvanized steel and / or stainless steel can be suitable.Alternatively or in addition to a steel material, the locking element can be made of an aluminum material and / or zinc material. Aluminum and zinc materials enable simple and cost-effective production of even complex geometries, for example by die casting, which can be particularly useful for the rear locking element. With regard to a space-saving design, it can be advantageous if the at least one locking element and the adjusting magnet, in particular assigned to the locking element, are adjustable independently of one another. This is particularly suitable for the at least one lateral locking element. Irrespective of this, it can be functionally expedient if the at least one locking element can be adjusted from the release position to the locking position and / or back independently of the adjusting magnet.Against the same background, it may be alternatively or additionally advisable for the at least one adjusting magnet to be adjustable independently of the locking element from the basic position to the unlocking position and / or back.

[0025] Alternatively, or in addition to independent adjustment, it may be advantageous, in terms of simple design, for the locking element and the adjustment magnet, particularly associated with the locking element, to be adjusted exclusively together. This is particularly suitable for the rear locking element.

[0026] Regardless of whether the locking element and the adjusting magnet are adjustable independently of one another or together, the adjustment of the at least one locking element from the locking position to the release position can be carried out in a structurally simple and reliable manner using a positive fit by the adjusting magnet, in particular assigned to the locking element. Thus, in particular, the at least one adjusting magnet can then adjust the at least one locking element from the locking position to the release position in a positive fit when adjusting from the basic position to the unlocking position. Alternatively or additionally, for the reasons mentioned, it may also be advisable for the at least one adjusting magnet to bear against the locking element when adjusting from the basic position to the unlocking position.

[0027] A space-saving design can also be achieved if the at least one locking element can be displaced between the locking position and the release position. This is particularly useful for the at least one lateral locking element. Alternatively or in addition to the displaceability of the locking element, the at least one adjusting magnet can be displaced between the basic position and the unlocking position. This is particularly useful if the adjusting magnet is assigned to a lateral locking element. Irrespective of this, the locking element and / or the adjusting magnet can be displaced particularly easily and reliably along the longitudinal axis of the locking element.Alternatively or additionally to being displaceable along the longitudinal axis of the locking element, it can be functionally and structurally simple if the at least one locking element and the adjusting magnet, in particular associated with the locking element, are displaceable along the same axis. Alternatively or additionally, a flat design of the pivot lever can be enabled if the displacement of the locking element and / or the adjusting magnet can occur at least substantially parallel to a contact plane of the pivot lever, in which the pivot lever can bear against the access control device.

[0028] Alternatively or in addition to being displaceable, the locking element can be pivotable about a pivot axis between the locking position and the release position. This is advantageous for the rear locking element in terms of a simple design. Alternatively or additionally, for the same reason, it can be advantageous for the adjusting magnet to be pivotable about a pivot axis between the basic position and the unlocking position, which is particularly advantageous for the adjusting magnet assigned to the rear locking element. Irrespective of this, it can also be advantageous for design reasons if the at least one pivot axis is arranged at least substantially parallel to a contact plane of the pivot lever, in which plane the pivot lever can rest against the access control device.Alternatively or additionally, for the same reason, it may also be appropriate if the pivot axis of the locking element and / or of the adjusting magnet is arranged at least substantially parallel to a locking axis about which the actuating lever can be pivoted between the locking position and the actuating position.

[0029] The at least one locking element can be held on the base part or on the actuating lever in a simple and expedient manner so that it can be adjusted between the locking position and the release position. The at least one locking element, in particular the lateral one, can then be held directly on the base part or actuating lever in a simple manner, for example. Alternatively or additionally, the locking element, in particular the rear one, can be held on the base part via an adapter element for design reasons. Independently of the locking element, the at least one adjusting magnet can also be held on the actuating lever or on the base part in a simple and expedient manner so that it can be adjusted between the basic position and the unlocking position. With regard to permanently reliable functionality, it can be advisable if the at least one locking element and / or the at least one adjusting magnet is held captive on the base part or actuating lever.This can be done simply and reliably using a form-fitting connection. Alternatively or additionally, in terms of reliable adjustment and at the same time a space-saving design, it may be advisable if the at least one locking element is adjustably held in a guide of the base part or the actuating lever, wherein a guide of the base part may be particularly suitable from a structural perspective. Irrespective of this, a holder in a guide is particularly suitable for the at least one lateral locking element. Alternatively or additionally, with the same background, the at least one adjusting magnet can be adjustably held in a guide of the actuating lever or the base part, wherein a guide of the actuating lever is particularly preferred from a structural perspective. A holder in a guide is particularly suitable if the adjusting magnet is assigned to a lateral locking element.

[0030] Regardless of how the locking element and the adjusting magnet are mounted on the base part or actuating lever, it can contribute to a space-saving design if the at least one locking element is mounted on the base part and the at least one adjusting magnet, in particular associated with the locking element, is mounted on the actuating lever, or vice versa. This is particularly suitable for the at least one lateral locking element. Regardless of this, it is particularly preferred from a design perspective if the locking element is mounted on the base part and the adjusting magnet is mounted on the actuating lever.

[0031] Alternatively or additionally, it may be advisable for a simple construction if the locking element and the adjusting magnet, in particular the one associated with the locking element, are both mounted on the base part or both on the actuating lever. This can be structurally simple, particularly for the rear locking element. Irrespective of this, a mounting on the base part may be particularly suitable for a simple construction. Alternatively or additionally, the adjusting magnet can be simply and conveniently mounted on the base part or actuating lever via the locking element.

[0032] In order to enable a flat design of the pivot lever on the side of the access control device facing the actuating lever, the locking element can be arranged, particularly regardless of its position, at least partially on the side of a contact plane facing away from the actuating lever, in which the pivot lever can rest against the access control device. This can be particularly useful for the rear locking element. Irrespective of this, a particularly flat design can be enabled if the locking element is arranged not only partially, but at least substantially, on the side of the contact plane facing away from the actuating lever.

[0033] If the locking element is arranged at least partially on the side of the contact plane facing away from the actuating lever, it can be functionally and structurally simple if the actuating lever has at least one locking section that extends through the contact plane in the locking position of the actuating lever. Then, the at least one locking section in the locking position of the actuating lever can form at least one positive connection with the locking element, in particular the rear locking element, in the locking position, blocking the pivoting of the actuating lever. In this case, it can be advantageous, with regard to a high level of security against forcible adjustment of the actuating lever, for the actuating lever to have at least two corresponding locking sections. Alternatively or additionally, the at least one locking section of the actuating lever can simply and expediently have the shape of a hook.

[0034] The locking element can be structurally simple and expediently comprised of an at least substantially L-shaped base body. This is particularly suitable for the rear locking element. Independently of this, it can further contribute to a simple and expedient design if the locking element can be pivoted between the locking position and the release position about a pivot axis extending through a free end of an L-shaped leg of the base body. Alternatively or additionally, the locking element can have at least one locking section projecting laterally from the base body to form the at least one positive connection blocking the pivoting of the actuating lever. This can further simplify the design.Then, in the locking position of the locking element, the at least one locking section can form at least one positive connection with the actuating lever in the locking position, blocking the pivoting of the actuating lever. Irrespective of this, with regard to high security against forcible adjustment of the actuating lever, it may be advantageous if the locking element has two laterally projecting locking sections. For the same reason, it may be particularly preferred if the locking sections project in opposite directions from the base body. Alternatively or additionally, it may be advantageous from a structural point of view for the at least one locking section to be connected to the base body in a connecting region of the two L-legs of the L-shaped base body.

[0035] Regardless of an L-shaped base body, it can be simple and expedient if the adjusting magnet is at least partially accommodated in a magnet receptacle of the locking element, in particular the one assigned to the adjusting magnet. This can be particularly useful for the adjusting magnet assigned to the rear locking element. Irrespective of this, the adjusting magnet can be particularly reliably accommodated not only partially, but at least substantially in the magnet receptacle. For the same reason, it can alternatively or additionally be appropriate if the magnet receptacle is designed to correspond to the adjusting magnet. Regardless of a corresponding design, the magnet receptacle can also be arranged at a free end of an L-leg of the L-shaped base body of the locking element for structural reasons.

[0036] In order to provide a reliable positive locking in a simple manner, the locking element can engage behind at least one undercut of the actuating lever and / or the actuating lever can engage behind at least one undercut of the locking element in a positive-locking manner when the actuating lever is in the locking position and the locking element is in the locking position. This is particularly suitable for the rear locking element. Irrespective of this, it can be advantageous, with regard to particularly high security against forced pivoting of the actuating lever, if the locking element engages behind two undercuts of the actuating lever and / or the actuating lever engages behind two undercuts of the locking element.Alternatively or additionally, it may be expedient for the at least one locking section of the locking element and / or the actuating lever to engage behind the at least one undercut and / or form the at least one undercut. Alternatively or additionally to engaging behind an undercut, a reliable positive locking connection can be achieved in a particularly space-saving manner if, in the locking position of the actuating lever, the at least one locking element positively engages in a locking receptacle of the actuating lever or the base part in the locking position. This can be particularly useful for the at least one lateral locking element.Irrespective of this, in the case where the at least one adjusting magnet, in particular the one associated with the locking element, is held in a guide, it can be structurally simple if the at least one locking receptacle is formed by the at least one guide of the adjusting magnet. Alternatively or additionally, it can also be structurally preferred if the actuating lever has the at least one locking receptacle. Irrespective of this, it can be expedient if the at least one locking element is arranged outside the locking receptacle in the release position, preferably independently of the position of the actuating lever.

[0037] To prevent the locking element from inadvertently entering the release position, at least one securing element can be provided to hold the at least one locking element in the locking position. The at least one locking element can then be held in the locking position by the at least one securing element when the actuating lever is in the locking position. Irrespective of this, an inadvertent retention of the locking element in the release position can be prevented if the at least one securing element is additionally designed to automatically adjust the at least one locking element from the release position to the locking position. The at least one locking element can then therefore be automatically adjustable from the release position to the locking position by the at least one securing element.Irrespective of this, with a plurality of locking elements, it may be expedient for the reasons mentioned if at least one securing element is assigned to each of the locking elements. Alternatively or additionally, holding the locking element in the locking position and / or automatically moving the locking element from the release position to the locking position can be achieved simply and conveniently by a securing force. For the same reason, it may also be appropriate for the securing force to be a magnetic force, in particular a magnetically attractive force.

[0038] If the securing force is a magnetic force, the at least one securing element can expediently be designed as a securing magnet, in particular a permanent magnet. The at least one securing magnet can then be formed by the at least one adjusting magnet in a space-saving manner. This is particularly suitable if the securing magnet is assigned to a lateral locking element. Alternatively, the at least one securing magnet and the at least one adjusting magnet can be designed as separate components. This can be advantageous for design reasons, in particular if the securing magnet is assigned to the rear locking element. Irrespective of this, it can be advantageous from a design perspective, particularly if the securing magnet is designed separately, for the at least one securing magnet to be held on the locking element or stationary on the base part.For the sake of simplicity, the at least one securing magnet can be held in a magnet receptacle, in particular one of a corresponding design. Alternatively or additionally, at least two securing magnets can be assigned to the locking element to increase the securing force. This can be particularly useful for the rear locking element. Alternatively or additionally, one of the two securing magnets can then expediently be held on the locking element and the other securing magnet can be held stationary on the base part.

[0039] To avoid that the adjustment magnet accidentally enters the

[0040] unlocked position, the pivot lever can have at least one holding element for holding the at least one adjusting magnet, in particular the one assigned to the lateral locking element, in the basic position. The at least one adjusting magnet can then be held in the basic position by the at least one holding element when the adjusting magnet has not been adjusted into the unlocked position by means of the key. In order to prevent the adjusting magnet from unintentionally remaining in the unlocked position, the at least one holding element can further be designed to automatically adjust the at least one adjusting magnet from the unlocked position to the basic position. The at least one adjusting magnet can then be automatically adjustable from the unlocked position to the basic position by the at least one holding element.Irrespective of this, a retaining element is particularly suitable for an adjusting magnet that is adjustable independently of the locking element, in particular the one associated with the adjusting magnet. Alternatively or additionally, the at least one retaining element can expediently be formed separately from the at least one securing element. Irrespective of this, for the sake of simplicity, in the case of a plurality of adjusting magnets, it may be appropriate for one retaining element to be associated with several adjusting magnets.

[0041] Holding the adjustment magnet in the home position and / or automatically adjusting the adjustment magnet from the unlocked position to the home position can be effected simply and expediently by a holding force. For the same reason, it may then be further appropriate for the holding force to be a magnetic holding force, in particular a magnetically attractive holding force. In particular if the holding force is magnetic, it may be preferred if the at least one holding element is formed from a ferromagnetic material. Alternatively or additionally, it may be functionally preferred if the at least one holding element is formed from a non-permanently magnetic material. Irrespective of this, the at least one holding element can be simply and expediently designed as a sheet metal, in particular a sheet metal strip.To simplify the pivoting of the actuating lever from the actuating position to the locking position, the at least one locking element can be automatically adjustable from the locking position to the release position when the actuating lever is pivoted from the actuating position to the locking position. Thus, pivoting the actuating lever from the actuating position to the locking position can cause the at least one locking element to be moved from the locking position to the release position. A complex, separate adjustment of the at least one locking element from the locking position to the release position can then be eliminated. Irrespective of this, the automatic adjustment of the at least one locking element can be carried out simply and reliably using a positive fit.

[0042] The automatic adjustment of the locking element from the locking position to the release position can be achieved in a structurally simple manner if the actuating lever has at least one sliding surface. Then, when the actuating lever is pivoted from the actuating position to the locking position, the at least one sliding surface of the actuating lever can slide along the at least one locking element, thereby automatically adjusting the locking element from the locking position to the release position. Alternatively or additionally, against the same background, the at least one locking element can have a sliding surface. Then, when the actuating lever is pivoted from the actuating position to the locking position, the sliding surface of the at least one locking element can slide along the actuating lever, thereby automatically adjusting the locking element from the locking position to the release position.With regard to particularly reliable adjustment of the locking element, it may be advantageous if the at least one sliding surface of the actuating lever and the sliding surface of the at least one locking element are designed to slide against one another. Irrespective of this, the at least one sliding surface can be structurally simply formed by a chamfer. Alternatively or additionally, it may be expedient if the at least one sliding surface of the actuating lever is arranged in the position in sliding contact with the at least one locking element and / or the sliding surface of the at least one locking element is arranged obliquely, for example at an angle of at least 30° and / or at most 60°, in particular approximately 45°, to the release direction of the locking element in the locking position.The release direction can be understood in particular as the direction in which the locking element can be adjusted from the locking position to the release position.

[0043] To facilitate pivoting the actuating lever out of the locking position, the actuating lever can be pivoted into the locking position against a restoring force. The restoring force can then assist pivoting the actuating lever out of the locking position. Independently of this, the restoring force can be provided in a simple manner by a spring means, for example, in the form of a leg spring.

[0044] In order to contribute to a high level of security against unauthorized unlocking of the operating lever in addition to simple pivoting of the operating lever, a force can act on the at least one locking element in the locking position due to the restoring force, which counteracts any adjustment of the locking element into the release position. In this case, it can be structurally simple if the force counteracting the adjustment into the release position is caused by a frictional connection. Irrespective of this, it can be structurally particularly simple if the frictional connection acts between the at least one locking element and the operating lever and / or between the at least one locking element and the base part.

[0045] A simple design of the locking mechanism can be achieved if the pivot lever has a key receptacle for at least partially, in particular at least predominantly, receiving the key. Then, in a use position, the key, for example a rod-shaped key, can be received at least partially, in particular at least predominantly, in the key receptacle, preferably inserted into the key receptacle. Independently of this, it can also contribute to a simple locking mechanism if the preferably elongated key receptacle extends along the longitudinal axis of the actuating lever and / or along the longitudinal axis of the base part.Alternatively or additionally, it can contribute to a compact design of the pivot lever if the key receptacle is formed by the operating lever and / or the base part, whereby for the same reason it can be particularly suitable if the key receptacle is formed at least substantially by the operating lever. Irrespective of this, a particularly flat design of the pivot lever can be achieved if the operating lever and the base part jointly form the key receptacle. Alternatively or additionally, it can be suitable for design reasons if at least two of the adjusting magnets, in particular those assigned to one of the lateral locking elements, and / or at least two holding elements are arranged on opposite sides, in particular long sides, of the key receptacle.

[0046] In a first particularly preferred embodiment of the pivot lever system, the key receptacle of the pivot lever and the key have corresponding cross-sections. This facilitates precise positioning of the key in the key receptacle when unlocking the operating lever. For the same reason, it may also be appropriate for the corresponding cross-sections to have corresponding shaped elements for aligning the key in the key receptacle. This ensures that the key can only be inserted into the key receptacle in a predetermined orientation, which simplifies handling. For the sake of simplicity, the shaped elements can be designed as shoulders.

[0047] Regardless of the corresponding cross-sections of the key receptacle and the key, the key can be designed as a master key. In this case, the key can expediently have at least one master key magnet assigned to an empty position in the pivot lever. In this case, in particular, no adjustment magnet of the pivot lever is assigned to the master key magnet. Instead, the at least one master key magnet can serve to unlock at least one further pivot lever, which can differ from the pivot lever of the pivot lever system with regard to the arrangement of the at least one adjustment magnet. In this way, differently coded pivot levers can be unlocked with one key.Against this background, it is particularly suitable if the at least one master key magnet is designed to adjust at least one adjustment magnet of the at least one further pivot lever from the home position to the unlocked position. Irrespective of this, the at least one further pivot lever can expediently be part of the pivot lever system. However, this is not absolutely necessary.

[0048] The invention will be explained in more detail below with reference to a drawing which merely represents an exemplary embodiment. The drawings schematically show

[0055] Fig. 8 shows the pivot lever system from Fig. 1 with the operating lever in the operating position in a side view.

[0056] In the figures, magnetic north poles of magnets are marked with “N” and magnetic south poles of magnets with “S”.

[0057] Fig. 1 shows a pivot lever system 1 comprising a pivot lever 2 with an actuating lever 3 in an actuating position in a perspective view. In addition to the actuating lever 3, the pivot lever 2 has a base part 4. In this case, the actuating lever 3 is held pivotably on the base part 4 via a turntable 5 such that the pivot lever 2 can be pivoted relative to the base part 4 about an actuating axis AB and a locking axis AA that is at least substantially perpendicular to the actuating axis AB. The base part 4 has a trough-shaped lever receptacle 6 in which the actuating lever 3 can be received. The actuating lever 3 has, on its rear side assigned to the base part 4, two hook-shaped locking sections 7 that protrude from the main body of the actuating lever 3 in the direction of the base part 4.The locking sections 7 are each provided to pass through a recess 8 in the bottom 9 of the base part 4.

[0058] In addition to the pivot lever 2, the pivot lever system 1 has a key 10 that fits the pivot lever 2. The key 10, which is rod-shaped in this case, has several permanent magnetic key magnets 11 that differ in their polarity. In this case, the key 10 is shown in a non-use position. To accommodate the key 10 in a use position, the pivot lever 2 has a key receptacle 12, which in the illustrated and thus preferred pivot lever 2 is formed predominantly by the actuating lever 3 and partially by the base part 4. In this case, the key receptacle 12 extends along the longitudinal axis LBH of the actuating lever 3 and the longitudinal axis LBT of the base part 4.

[0059] In the actuating position shown in Fig. 1, the actuating lever 3 is pivoted out of the lever receptacle 6, so that the actuating lever 3 can be pivoted about the actuating axis AB relative to the base part 4. To lock the actuating lever 3 to the base part 4, the actuating lever 3 can be pivoted about the locking axis AA toward the base part 4 into the locking position shown in Fig. 2.

[0060] Fig. 2 shows the pivot lever 2 with the actuating lever 3 in the locked position in a perspective view. The actuating lever 3 is at least substantially received in the lever receptacle 6 of the base part 4, so that pivoting of the actuating lever 3 about the actuating axis AB is positively blocked. The key receptacle 12 formed by the actuating lever 3 and the base part 4 has a key opening 13 at its longitudinal end associated with the free end of the actuating lever 3, through which the key 10 (not shown) can be inserted into the key receptacle 12.

[0061] Figs. 3A-B show the pivot lever 2 with the actuating lever 3 in the locking position without the key 10 in two sectional views along the sectional plane 111A-111A shown in Fig. 2 and the sectional plane 111B-111B shown in Fig. 3A. The pivot lever 2 is fastened by means of the base part 4 to an access control device 14 not shown in Fig. 3A, for example in the form of a sheet metal door and / or sheet metal flap.

[0062] In the illustrated and, in this respect, preferred embodiment, the pivot lever 2 has eleven lateral locking elements 15, in this case designed as steel pins, which are arranged along the longitudinal axis LBT of the base part 4, distributed on opposite sides of the longitudinal axis LBT. The lateral locking elements 15 are held captively on the base part 4 in guides 16 of the base part 4. The lateral locking elements 15 are each displaceable along their longitudinal axis LVE in the associated guide 16.

[0063] Each of the lateral locking elements 15 is assigned an adjusting magnet 17 made of a permanent magnetic material. The adjusting magnets 17 are held captively on the actuating lever 3 in guides 18 of the actuating lever 3, wherein the adjusting magnets 17 are each displaceable along the longitudinal axis LVE of the associated lateral locking element 15 in the guides 18. By displacing the adjusting magnets 17 outward, the lateral locking elements 15 are also displaced outward in a positive-locking manner.

[0064] The actuating lever 3 has a holding element 19 on each of the opposite longitudinal sides of the key receptacle 12. The holding elements 19 are designed as ferromagnetic sheet metal strips, which in this case extend along the longitudinal axis LBH of the actuating lever 3 and along the adjusting magnets 17.

[0065] The lateral locking elements 15 are each arranged in a locking position. In the locking position, the locking elements 15 held on the base part 4 engage in a positive-locking manner in locking receptacles 20 of the actuating lever 3, wherein the locking receptacles 20 are formed in this case by the guides 18 for the adjusting magnets 17. In this way, the pivoting of the actuating lever 3 about the locking axis AA from the illustrated locking position and the lever receptacle 6 is positively blocked by the lateral locking elements 15.

[0066] The adjusting magnets 17 assigned to the lateral locking elements 15 are each arranged in a home position. In the home position, the adjusting magnets 17 hold the lateral locking elements 15 in the illustrated locking position through the magnetically attractive interactions between the adjusting magnets 17 and the locking elements 15. This prevents the lateral locking elements 15 from inadvertently reaching a position in which the locking elements 15 would allow the actuating lever 3 to pivot out of the locking position and the lever receptacle 6. In the illustrated and thus preferred embodiment, the adjusting magnets 17 also function as securing elements 21 for the lateral locking elements 15. The adjusting magnets 17 are in turn held in the illustrated home position through the magnetically attractive interactions with the ferromagnetic sheet metal strips 19.

[0067] In the illustrated and, in this respect, preferred embodiment, a spring means 22, which in this case is designed as a leg spring, acts between the actuating lever 3 and the rotary plate 5. A restoring force FR acts on the actuating lever 3 through the spring means 22, which supports the pivoting of the actuating lever 3 about the locking axis AA out of the lever receptacle 6. The restoring force FR creates a frictional connection between the lateral locking elements 15 on the one hand and the actuating lever 3 and the base part 4 on the other hand, which counteracts any displacement of the corresponding locking element 15 out of the associated locking receptacle 20.

[0068] 4A-C show sections of the pivot lever 2 with the actuating lever 3 in the locked position without the key 10 in two sectional views along the sectional planes 1VA-1VA and 1VB-1VB shown in Fig. 3A and an isometric view obliquely from below. For the sake of clarity, Fig. 4C only shows the actuating lever 3 as well as a rear locking element 23 and an adapter element 24 of the pivot lever 2. The rear locking element 23, which in this case is die-cast from an aluminum and / or zinc material, is arranged at least substantially on the side of a contact plane E facing away from the actuating lever 3, in which the pivot lever 2 rests against the access control device 14. The rear locking element 23 is held on the adapter element 24 so as to be pivotable about a pivot axis AS that is at least substantially parallel to the contact plane E.In the present case, the rear locking element 23 is held between two longitudinal struts 25 of the adapter element 24, which are connected to each other in the region of their longitudinal ends. The adapter element 24 is in turn attached to the base part 4 by means of a screw connection 26.

[0069] The rear locking element 23 has a substantially L-shaped base body TI and two locking sections 28 that protrude laterally from the L-shaped base body TI. The pivot axis AS of the rear locking element 23 extends through a free end of one of the two L-legs of the L-shaped base body 27. At the free end of the other of the two L-legs of the L-shaped base body TI, a magnet receptacle 29 is provided, in which an adjusting magnet 30 is assigned to the rear locking element 23 and made of a permanent magnetic material. In addition to the adjusting magnet 30, a likewise permanent magnetic securing magnet 31 is held on the rear locking element 23 in a magnet receptacle 32 of the locking element 23.The securing magnet 31 held on the rear locking element 23 interacts with a permanent magnetic securing magnet 33 which is held stationary on the base part 4 via the adapter element 24 and which is received in a magnet receptacle 34 of the adapter element 24.

[0070] The rear locking element 23 and the adapter element 24 are shielded from the environment by a cover cap 35. In this case, the cover cap 35 is secured to the base part 4 by a screw connection 36, with the access control device 14 clamped between the base part 4 and the cover cap 35. In this way, the pivot lever 2 is attached to the access control device 14 in the illustrated and, in this respect, preferred embodiment.

[0071] To prevent coarse dirt from entering the key receptacle 12, which in this case is formed by the base part 4 and the actuating lever 3, a protective flap 37 is provided in the region of the key opening 13 of the key receptacle 12. In the illustrated and thus preferred embodiment, the protective flap 37 is pivotally mounted on the actuating lever 3 between a position that at least substantially closes the key opening 13 and a position that releases the key opening 13.

[0072] The rear locking element 23 is arranged in a locking position. In the locking position, the locking sections 28 of the rear locking element 23 each engage behind an undercut 38 of the actuating lever 3. In this case, the undercuts 38 of the actuating lever 3 are each formed by one of the two hook-shaped locking sections 7 of the actuating lever 3, which extend through the recesses 8 of the base part 4 and the contact plane E. The hook-shaped locking sections 7 of the actuating lever 3, in turn, each engage behind an undercut 39 of one of the locking sections 28 of the rear locking element 23. In this way, the pivoting of the actuating lever 3 out of the illustrated locking position is positively blocked by the rear locking element 23.

[0073] Due to the magnetically attractive interaction between the securing magnet 31 held on the rear locking element 23 and the securing magnet 33 held on the adapter element 24, the locking element 23 is held in the illustrated locking position and thus also the adjusting magnet 30 held on the locking element 23 is held in the illustrated basic position. In this way, the rear locking element 23 is prevented from inadvertently reaching a position in which it would release the pivoting of the actuating lever 3. In the present case, the restoring force FR of the spring means 22 (not shown in Figs. 4A-C) also creates a frictional connection between the hook-shaped locking sections 7 of the actuating lever 3 and the locking sections 28 of the rear locking element 23, which counteracts pivoting of the locking element 23 about the pivot axis AS.

[0074] In order to pivot the actuating lever 3 from the locking position shown in Figs. 3A-B and 4A-C about the locking axis AA into an actuating position, the pin-shaped key 10 (not shown here) can be inserted through the key opening 13 into the key receptacle 12 and thus adjusted into a use position. In this case, the protective flap 37 is pivoted in a form-fitting manner from the position shown in Fig. 4A, which at least substantially closes the key opening 13, into a position which releases the key opening 13 by contact with the key 10.

[0075] Fig. 5A-B show the pivot lever system 1 with the operating lever 3 in the

[0076] locking position and the key 10 in the use position in two

[0077] Sectional views along the sectional plane VA-VA shown in Fig. 2 and the sectional plane VB-VB shown in Fig. 5A. The key magnets 11 of the key 10 are each assigned to one of the lateral locking elements 15 of the pivot lever 2 and the associated adjusting magnet 17. The magnetically repulsive interactions between the key magnets 11 and the adjusting magnets 17 are greater than the magnetically attractive interactions between the adjusting magnets 17 and the ferromagnetic holding elements 19, so that the adjusting magnets 17 are each displaced along the longitudinal axis LVE of the associated lateral locking element 15 from the basic position (Fig. 3A-B) into an unlocked position.

[0078] By moving the adjusting magnets 17 assigned to the lateral locking elements 15 from the basic position (Fig. 3A-B) into the unlocking position, the lateral locking elements 15 are each moved along their longitudinal axis LVE from the locking position (Fig. 3A-B) into a release position. In the release position, the lateral locking elements 15 are arranged outside the locking receptacles 20 of the actuating lever 3, so that the pivoting of the actuating lever 3 about the locking axis AA out of the lever receptacle 6 is released by the lateral locking elements 15.

[0079] The adjusting magnets 17 assigned to the lateral locking elements 15 differ in their pole orientations. In this case, the magnetic poles of adjacent adjusting magnets 17 are aligned opposite each other. However, this is not absolutely necessary. Rather, the magnetic poles of the adjusting magnets 17 can be aligned in any direction, thus enabling any desired coding.

[0080] When the key 10 is pulled out of the key receptacle 12, the adjusting magnets 17 assigned to the lateral locking elements 15 are automatically displaced from the illustrated unlocking position in the direction of the holding elements 19 into the basic position (Fig. 3A-B) due to the magnetically attractive interactions with the ferromagnetic holding elements 19. Due to the magnetically attractive interactions between the adjusting magnets 17 and the lateral locking elements 15, the displacement of the adjusting magnets 17 in turn causes the locking elements 15 to be automatically displaced from the illustrated release position into the locking position (Fig. 3A-B), in which the locking elements 15 engage in the locking receptacles 20 of the actuating lever 3.

[0081] The key 10 is designed as a master key 10 and, in addition to the key magnets 11, has a master key magnet 40. The master key magnet 40 and the key magnets 11 assigned to the lateral locking elements 15 are designed identically in the illustrated and, in this respect, preferred embodiment. In contrast to the key magnets 11, however, the master key magnet 40 is not assigned to a locking element 15, 23 and thus also not to an adjustment magnet 17, 30 of the pivot lever 2. Instead, the master key magnet 40 is assigned to an empty space 41 of the pivot lever 2. In this case, a guide 16 for a locking element and a guide 18 for an adjustment magnet are provided at the empty space 41. However, this is not absolutely necessary. For example, the pivot lever 2 could alternatively be solid in the area of ​​the empty space 41.By means of the master key magnet 40, at least one further pivot lever 2 can be unlocked, which has a locking element assigned to the master key magnet 40 and an adjustment magnet assigned to the master key magnet 40 at the position of the empty space 41.

[0082] In the illustrated and thus preferred embodiment, the cross-section of the key 10 is designed to correspond to the cross-section of the key receptacle 12. Both the key 10 and the key receptacle 12 have a shaped element 42 in the form of a shoulder in cross-section. This ensures that the key 10 can only be inserted into the key receptacle 12 in the specified orientation. Figs. 6A-B show sections of the pivot lever system 1 with the actuating lever 3 in the locked position and the key 10 in the use position in two sectional views along the sectional planes V1A-V1A and V1B-V1B shown in Fig. 5A.In addition to the key magnets 11, which are assigned to the lateral locking elements 15 and the associated adjusting magnets 17, the key 10 in this case has two key magnets 43, which are assigned to the rear locking element 23 and the associated adjusting magnet 30. The magnetically repulsive interactions between the key magnets 43 and the adjusting magnet 30 are greater than the magnetically attractive interactions between the two securing magnets 31, 33 assigned to the rear locking element 23, so that the adjusting magnet 30 is pivoted about the pivot axis AS from the basic position (Fig. 4A-C) into an unlocked position.

[0083] By pivoting the adjusting magnet 30 from the basic position (Fig. 4A-C) into the unlocked position, the rear locking element 23 is also pivoted about the pivot axis AS from the locked position (Fig. 4A-C) into a release position. In the release position of the rear locking element 23, the mutual engagement between the locking element 23 and the hook-shaped locking sections 7 of the actuating lever 3 is canceled, so that the pivoting of the actuating lever 3 about the locking axis AA out of the lever receptacle 6 is released by the rear locking element 23. When the key 10 is withdrawn from the key receptacle 12, the magnetically attractive interaction between the securing magnets 31, 33 automatically moves the rear locking element 23 from the illustrated unlocked position about the pivot axis AS into the locked position (Fig.4A-C), in which the locking element 23 blocks the pivoting of the actuating lever 3. In order to prevent the rear locking element 23 from reaching a position in which the magnetic interaction between the two securing magnets 31, 33 is at least substantially canceled, the locking element 23, in the illustrated release position, rests with its laterally projecting locking sections 28 against the longitudinal struts 25 of the adapter element 24. Thus, further pivoting of the rear locking element 23 about the pivot axis AS away from the securing magnet 33 held on the adapter element 24 is positively blocked by the adapter element 24.

[0084] From the locking position shown in Figs. 5A-B and 6A-B, the operating lever 3 can be pivoted together with the key 10 inserted into the key receptacle 12 about the locking axis AA out of the lever receptacle 6 into an operating position, for example the one shown in Fig. 1.

[0085] Fig. 7A shows a section of the pivot lever 2 in the region of one of the lateral locking elements 15 without the key 10 in a sectional view along the sectional plane V11A-V11A shown in Fig. 3A, with the actuating lever 3 in a position at least partially pivoted out of the lever receptacle 6. The adjusting magnet 17 associated with the lateral locking element 15 is arranged in the basic position and held there by the magnetically attractive interaction with the associated holding element 19. The lateral locking element 15, which is freely displaceable along its longitudinal axis LVE in the associated guide 16, is arranged in the locking position.

[0086] The actuating lever 3 has, below the guide 18 for the adjusting magnet 17, a sliding surface 44 in the form of a chamfer 44 associated with the lateral locking element 15. In the illustrated and, in this respect, preferred embodiment, the lateral locking element 15 also has, at its longitudinal end associated with the actuating lever 3, a sliding surface 45 in the form of a chamfer 45 extending around the longitudinal axis LVE of the locking element 15. The sliding surfaces 44, 45 are arranged obliquely, in this case at an angle of approximately 45°, to a release direction RF of the locking element 15.

[0087] When the actuating lever 3 is pivoted toward the lever receptacle 6, the sliding surface 44 of the actuating lever 3 and the sliding surface 45 of the lateral locking element 15 slide against each other. As a result, the lateral locking element 15 is displaced from the illustrated locking position in the release direction RF into the release position (Fig. 5B). This prevents the lateral locking element 15 from blocking the pivoting of the actuating lever 3 into the lever receptacle 6. As soon as the actuating lever 3 is then in the locking position received in the lever receptacle 6 (Fig. 3B) and the locking receptacle 20 is arranged in alignment with the lateral locking element 15, the locking element 15 is automatically moved again from the release position (Fig. 5B) into the locking position shown by the magnetically attractive interaction with the adjusting magnet 17, which in this case functions as a securing element 21.

[0088] Figs. 7B-C show sections of the pivot lever 2 without the key 10 in sectional views along the sectional planes V11B-V11B and VIIC-VIIC shown in Fig. 3A, with the actuating lever 3 in a position at least partially pivoted out of the lever receptacle 6. The rear locking element 23 is arranged in the locking position and held there by the magnetically attractive interaction between the securing magnets 31, 33 associated with the locking element 23.

[0089] In the illustrated and thus preferred embodiment, the hook-shaped locking sections 7 of the actuating lever 3 and the locking sections 28 of the rear locking element 23 each have a sliding surface 46, 47 in the form of a bevel. The sliding surfaces 46, 47 are arranged obliquely, in this case at an angle of approximately 45°, to a release direction RF of the rear locking element 23. When the actuating lever 3 is pivoted in the direction of the lever receptacle 6, the sliding surfaces 46 of the hook-shaped locking sections 7 of the actuating lever 3 slide along the sliding surfaces 47 of the locking sections 28 of the rear locking element 23. As a result, the rear locking element 23 is moved against the magnetically attractive interaction between the securing magnets 31, 33 from the illustrated locking position in the release direction RF into the release position (Fig.6A-B) so that the hook-shaped locking sections 7 of the actuating lever 3 can pass the locking sections 28 of the rear locking element 23. This prevents the rear locking element 23 from blocking the pivoting of the actuating lever 3 into the lever receptacle 6. As soon as the actuating lever 3 is then in the locking position received in the lever receptacle 6 (Fig. 4A-B), the rear locking element 23 is automatically pivoted again from the release position (Fig. 6A-B) into the illustrated locking position due to the magnetically attractive interaction between the securing magnets 31, 33.

[0090] Fig. 8 shows a side view of the pivot lever system 1 with the actuating lever 3 in the actuating position. The actuating lever 3 of the pivot lever 2 is connected in a rotationally fixed manner with respect to the actuating axis AB to a locking device 48, which in this case is designed as a rotary latch, which is arranged on the side of the contact plane E opposite the actuating lever 3. By pivoting the actuating lever 3 about the actuating axis AB, the locking device 48 can also be pivoted about the actuating axis AB. In this way, the locking device 48 can be pivoted, for example, between a locking position that blocks opening of the access control device 14 and an open position that allows opening of the access control device 14.
