Description

Technical Field

[0001] The invention relates to a swivel lever for operating a locking device (particularly a latch and / or a lever lock) of an access control device (particularly a door and / or a flap), the swivel lever having a base part for fixing the swivel lever, in particular, on the access control device, and an operating lever for operating the locking device, wherein the operating lever can be pivoted relative to the base part between a stop position for locking the operating lever on the base part and an operating position for operating the locking device, and / or can be pivoted when the locking device is operated, and wherein at least one latching element is provided for preventing the operating lever from being pivoted from the stop position to the operating position without authorization, the latching element being adjustable between a latching position for preventing the operating lever from pivoting in a form-fitting manner, and a release position for releasing the operating lever from pivoting. In addition, the invention relates to a swivel lever system having at least one such swivel lever and a key adapted to the swivel lever. Background Art

[0002] Access control devices, with which access can be locked or released, are known in various designs, for example in the form of doors or flaps. Independently of their design, the access control device often has at least one locking device in order to prevent the access control device from being accidentally moved from a position that locks the access to a position that releases the access and / or being adjusted accordingly by unauthorized manipulation.

[0003] As a locking device, for example, a latch is known. The latch typically has at least one latch, which can be adjusted between a position for preventing the access control device from being opened in a form-fitting manner and a position for releasing the access control device from being opened. Here, latches, in which the latch can be swung and / or rotated, are often also referred to as rotary latches. In addition to latches, so-called rod locks are known, which typically have at least one rod element. Here, at least one rod element can fix the access control device at two or more points that are spaced apart from each other, for example opposite each other, for example on a frame. This can increase the security against unauthorized opening of the access control device.

[0004] Regardless of the design of the locking device, a pivot lever is usually used to actuate the locking device. The pivot lever usually comprises a base part, with which the pivot lever can be fastened to the access control device, and an operating lever, which is used to actuate the locking device. The operating lever can usually be pivoted relative to the base part between a locking position, in which the operating lever can be locked on the base part, and an operating position, in which the locking device can be actuated by means of the operating lever. The pivot lever offers the advantage that high torques can be introduced into the locking device with little effort.

[0005] In order to prevent the operating lever from being pivoted from the locking position into the operating position by unauthorized persons, for example, the pivot lever usually has at least one latching element. Here, the at least one latching element can usually be adjusted between a latching position, in which the latching element prevents the operating lever from being pivoted from the locking position into the operating position in a form-fitting manner, and a release position, in which the latching element releases the pivoting of the operating lever from the locking position into the operating position. In order to adjust the at least one latching element from the locking position into the release position, a key adapted to the pivot lever is usually provided.

[0006] Such a pivot lever and such a pivot lever system are known from DE 10 2020 108 484 A1. Here, at least one latching element is designed as a latching magnet, and the key has at least one key magnet, so that the latching magnet can be adjusted from the latching position to the release position by magnetic interaction with the key magnet. This has the advantage that, when the operating lever is closed, at least one latching magnet does not have to be accessible from the outside in order to be able to be adjusted from the latching position to the release position. As a result, the latching mechanism can be better protected against external dirt and damage, for example caused by malicious vandalism. However, there is still a need for a pivot lever with improved properties. Summary of the invention

[0007] The object of the present invention is therefore to design and improve a pivot lever and a pivot lever system of the type mentioned at the outset and described in detail above in such a way that the properties of the pivot lever are improved while achieving a high degree of protection against external dirt and damage.

[0008] This object is achieved in a pivot lever according to the preamble of claim 1 in that at least one latching element can be adjusted from a latching position to a released position by adjusting at least one adjusting magnet from an original position to an unlocked position, wherein at least one adjusting magnet can be adjusted from an original position to an unlocked position by magnetic interaction with at least one key magnet of a key adapted to the pivot lever, and wherein at least one latching element and at least one adjusting magnet consist of different materials.

[0009] In addition, the purpose is achieved according to claim 16 by a swing lever system, which has at least one swing lever according to any one of claims 1 to 15 and a key adapted to the swing lever, the key including at least one key magnet, which is used to adjust at least one adjustment magnet of the swing lever from an original position to an unlocked position.

[0010] According to the invention, the swivel lever therefore has at least one adjusting magnet, which can be adjusted from a home position into an unlocked position. Here, by adjusting the at least one adjusting magnet from the home position into the unlocked position, the at least one latching element can be adjusted from the latched position into the released position. The at least one adjusting magnet can in turn be adjusted from the home position into the unlocked position by magnetic interaction with at least one key magnet of a key adapted to the swivel lever. Thus, the magnetic interaction between the at least one adjusting magnet and the at least one key magnet can cause the adjusting magnet to be adjusted from the home position into the unlocked position, which in turn can cause the at least one latching element to be adjusted from the latched position into the released position. In this way, on the one hand, a high degree of protection against external dirt and damage is achieved, because in the stop position of the operating lever, neither the adjusting magnet nor the latching element need to be accessible from the outside in order to adjust the latching element from the latched position into the released position. More precisely, in the stop position of the operating lever, the at least one adjusting magnet and / or the at least one latching element are not accessible from the outside. On the other hand, it is possible for the at least one latching element to consist of a different material than the at least one adjusting magnet. The materials and the material properties of the latching element and the adjusting magnet can thus be adapted independently of one another to the respective intended use, and in this way the properties of the pivot lever are ultimately improved. In particular, the at least one latching 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] In order not to impair the function of the at least one adjusting magnet, the base body of the base part, the operating lever and / or the key can be made of a non-ferromagnetic material. Aluminum and / or zinc are particularly suitable materials for this purpose. In principle, the base body of the base part, the operating lever and / or the key can be produced independently of the material and particularly economically by die casting.

[0012] The base part (which can be constructed in one piece or in multiple pieces) is provided in particular for fastening the pivot lever to the access control device. However, it is also conceivable in principle to fasten the pivot lever to another component than the access control device, for example to a frame carrying the access control device, for example a cabinet, by means of the base part. Independently of this, the operating lever can be held pivotably on the base part in a suitable manner.

[0013] The operating lever can be arranged in such a way that the locking device is actuated when the operating lever is in the actuating position. The locking device can then be actuated by pivoting the operating lever from the locking position into the actuating position. Preferably, however, the operating lever can be pivoted about a locking axis between the locking position and the actuating position and in the actuating position can be pivoted about an actuating axis that is inclined, in particular at least substantially perpendicular, to the locking axis in order to actuate the locking device.

[0014] Regardless of the design of the actuating position, it can be provided that the actuating lever is at least partially, in particular at least substantially, accommodated in the lever receptacle of the base part in the locking position. This can not only contribute to a flat design of the pivot lever, but also to good protection of the latch mechanism from external influences. The lever receptacle can be designed as a recess in a suitable manner. In principle, regardless of whether the actuating lever is accommodated in the lever receptacle, it can be provided that in the locking position of the actuating lever, a pivoting of the actuating lever about the actuating axis is prevented in a form-fitting manner.

[0015] The magnetic interaction between at least one adjusting magnet and, in particular, a key magnet corresponding to the adjusting magnet can be, for example, a magnetic attraction interaction. However, it is functionally preferred that the magnetic interaction is a magnetic repulsion interaction. Independently of this, in the use state of the key, the adjusting magnet can be adjusted into the unlocking position in a suitable manner by the magnetic interaction between at least one adjusting magnet and, in particular, a key magnet corresponding to the adjusting magnet.

[0016] The swivel lever and / or the swivel lever system can include a locking device and / or an access control device as required. However, this is not mandatory.

[0017] For better understanding and to avoid unnecessary repetition, the following describes the swivel lever and the swivel lever system together without distinguishing the swivel lever and the swivel lever system in detail. However, it is clear to a professional from the context which is the particularly preferred feature of the swivel lever and / or the swivel lever system.

[0018] In a first particularly preferred design of the swivel lever, the swivel lever has at least two latching elements. In this way, the safety of violently adjusting the swivel lever out of the stop position can be improved. For the same reason, it can be more suitable that the swivel lever has at least three, at least four, preferably at least six, and particularly preferably at least eight latching elements. Regardless of the specific number, these latching elements can be appropriately adjusted between the latching position that prevents the operating lever from pivoting in a form-fitting manner and the release position that releases the operating lever to pivot. In terms of the high safety of the unauthorized unlocking of the operating lever, it can be further provided that the swivel lever has a number of adjustment magnets corresponding to the number of latching elements, and these adjustment magnets are respectively assigned to one of the latching elements. Then, these latching elements can be appropriately adjusted from the latching position to the release position by adjusting the corresponding adjustment magnets from the original position to the unlocking position, wherein these adjustment magnets can be adjusted from the original position to the unlocking position by magnetically interacting with the key magnet of the key. It can be further provided that the polarity directions of at least two of the adjustment magnets are different with respect to the respective unlocking directions. In this way, a kind of encryption can be achieved, which can help to increase the security against unauthorized unlocking. It is more appropriate that the polarity direction of at least two adjacently arranged adjusting magnets is different with respect to the respective unlocking direction. Independently of this, the unlocking direction is in principle particularly the direction in which the adjusting magnet can be adjusted from the initial position into the unlocking position.

[0019] Independently of the number of latching elements and adjusting magnets, it is helpful for the flat design of the swivel lever that the swivel lever comprises at least one lateral latching element, which is used to prevent the pivoting of the operating lever in a form-fitting manner on the longitudinal side of the operating lever. Thus, at least one lateral latching element in the latched position prevents the operating lever from pivoting from the stop position to the operating position in a form-fitting manner on the longitudinal side of the operating lever. Independently of this, it can be provided that the swivel lever comprises at least two, preferably at least four, in particular at least six, particularly preferably at least eight lateral latching elements for the high safety of the violent adjustment of the operating lever. Thus, for the same reason, it can be particularly provided that the lateral latching element is configured to prevent the pivoting of the operating lever in a form-fitting manner on the opposite longitudinal side of the operating lever. Independently of this, at least one lateral latching element can be simply and appropriately configured as a pin.

[0020] As an alternative or in addition to the lateral latching element, in order to protect against unauthorized adjustment of the operating lever out of the locking position, provision can be made for the pivot lever to have at least one rear latching element, which serves to prevent a pivoting of the operating lever in a form-fitting manner on the rear side of the operating lever corresponding to the base part. The rear latching element in the latching position can then prevent a pivoting of the operating lever from the locking position into the operating position in a form-fitting manner on the rear side of the operating lever corresponding to the base part.

[0021] In terms of simple and cost-effective production and flexible use of the swivel lever, it can be provided that at least one adjusting magnet is made of a permanent magnetic material. Permanent magnets can (for example, in contrast to electromagnets) permanently generate a magnetic field without an external energy supply, in particular an at least substantially constant magnetic field. Independently of this, neodymium iron boron (Nd2Fe14B) can be suitable as a permanent magnetic material, which can achieve high magnetic field strengths at reasonable cost. As an alternative or in addition to the permanent magnetic design of the adjusting magnet, at least one latching element can preferably be made of a non-permanent magnetic material. The non-permanent magnetic material can be suitable for the latching element, for example, in terms of its mechanical properties and / or production technology properties.

[0022] In terms of function, it can be provided that at least one latching element is made of a ferromagnetic material. The latching element can then be adjusted by magnetic interaction with an adjusting magnet (in particular provided on the latching element). Independently of this, a ferromagnetic material can be suitable in particular for at least one lateral latching element. As an alternative to a ferromagnetic design, the latching element can be made of a non-ferromagnetic material. This is suitable in terms of production technology, in particular in the case of latching elements with complex geometries, which can be particularly advantageous for rear latching elements.

[0023] With regard to the safety latch against the violent adjustment of the operating lever out of the stop position, it can be provided that the material of at least one latching element has a higher shear strength than the material of an adjusting magnet, which is in particular provided on the latching element. As a result, the safety against breakage of the latching element, on which high shear forces usually act when the operating lever is violently adjusted out of the stop position, can be increased. In the same context, it can be provided, for example, that the shear strength of the material of at least one latching element is at least 1.2 times, if necessary at least 1.5 times, preferably at least 2 times, in particular at least 3 times, particularly preferably at least 4 times the shear strength of the material of the adjusting magnet. Independently of the respective ratio, the shear strength of the material of at least one latching element can be, for example, at least 50 N / mm 2 , preferably at least 100N / mm 2 , especially at least 150N / mm 2 .

[0024] Independently of the shear strength, the latching element can be manufactured by die casting. Die casting allows complex geometries to be manufactured economically, which is particularly suitable for the rear latching element. As an alternative or in addition to the production by die casting, at least one latching element can be composed of a metal material. Metallic materials are particularly suitable for latching elements due to their properties. This is especially true for steel because of its mechanical properties. Steel can be particularly suitable for at least one lateral latching element. Independently of this, ferritic steel can be particularly preferred in terms of function because it is generally strongly magnetic. In order to avoid corrosion as an alternative or in addition, galvanized steel and / or stainless steel can be suitable. As an alternative or in addition to steel, the latching element can be composed of aluminum and / or zinc. Aluminum and zinc allow complex geometries to be manufactured simply and cost-effectively, for example by die casting, which can be particularly suitable for the rear latching element.

[0025] In terms of a space-saving design, it can be provided that at least one latching element and in particular an adjusting magnet assigned to the latching element can be adjusted independently of one another. This applies in particular to at least one lateral latching element. Independently of this, it can be functionally expedient for at least one latching element to be adjustable from a release position into a latching position and / or back independently of the adjusting magnet. In the same context, it can alternatively or additionally be provided that at least one adjusting magnet can be adjusted from a home position into an unlocking position and / or back independently of the latching element.

[0026] Alternatively or in addition to the independent adjustment, in terms of a simple design, provision can be made for the latching element and, in particular, the adjusting magnet assigned to the latching element to be adjustable only together. This applies in particular to the rear latching element.

[0027] Regardless of whether the latching element and the adjusting magnet are adjustable independently of one another or together, the adjusting magnet, which is in particular provided on the latching element, can be used to adjust the at least one latching element from the latching position into the released position in a simple and reliable manner in terms of design. In particular, the at least one adjusting magnet can then adjust the at least one latching element from the latching position into the released position in a form-fitting manner during adjustment from the initial position into the unlocked position. Alternatively or additionally, for the reasons mentioned above, it can be provided that the at least one adjusting magnet can rest against the latching element during adjustment from the initial position into the unlocked position.

[0028] It can also be helpful for the space-saving configuration that at least one latching element can be moved between a latching position and a release position. This is particularly applicable to at least one lateral latching element. Instead of or in addition to the movability of the latching element, in the same context, at least one adjusting magnet can be moved between an original position and an unlocked position. This is particularly suitable when the adjusting magnet is arranged on the lateral latching element. Independently of this, the movement of the latching element and / or the adjusting magnet can be realized particularly simply and reliably along the longitudinal axis of the latching element. Instead of or in addition to the movability along the longitudinal axis of the latching element, if at least one latching element and the adjusting magnet especially arranged on the latching element can be moved along the same axis, it can be simple in function and structure. If the movement of the latching element and / or the adjusting magnet can be carried out at least substantially parallel to the abutment plane of the swing lever (in which the swing lever can be abutted on the access control device), then a flat structure of the swing lever can be realized alternatively or additionally.

[0029] Alternatively or in addition to the movability, the latching element can be pivoted about a swivel axis between a latching position and a release position. This applies to the rear latching element in terms of a simple configuration. Alternatively or in addition, for the same reasons, it can be provided that the adjusting magnet can be pivoted about a swivel axis between a home position and an unlocked position, which is particularly applicable to an adjusting magnet provided on the rear latching element. Independently of this, it can further be provided for configurational reasons that at least one swivel axis is arranged at least substantially parallel to a contact plane of a swivel lever, in which the swivel lever can rest on the access control device. Alternatively or in addition, for the same reasons, it can also be provided that the swivel axis of the latching element and / or the adjusting magnet is arranged at least substantially parallel to a stop axis, about which the operating lever can pivot between the stop position and the operating position.

[0030] At least one latching element can be simply and suitably held on a base part or an operating lever in an adjustable manner between a latching position and a release position. Thus, at least one particularly lateral latching element can be held directly on a base part or an operating lever in a simple manner, for example. Alternatively or additionally, the latching element at the rear can be held on a base part by an adapter element for configuration reasons. Independently of the latching element, at least one adjusting magnet can also be simply and suitably held on an operating lever or a base part in an adjustable manner between an original position and an unlocked position. Here, in terms of a durable and reliable working method, it can be provided that at least one latching element and / or at least one adjusting magnet is constrainedly held on a base part or an operating lever. This can be realized simply and reliably in a form-fitting manner. Alternatively or additionally, in terms of a reliable adjustment and a space-saving design at the same time, it can be provided that at least one latching element is adjustable and held in a guide portion of a base part or an operating lever, wherein the guide portion of the base part can be particularly suitable in structure. Independently of this, the holding of at least one lateral latching element in a guide portion is particularly suitable. Alternatively or additionally, in the same context, at least one adjusting magnet is adjustably held in a guide of the operating lever or the base part, wherein the guide of the operating lever is particularly preferred in terms of construction. Here, holding in the guide is particularly suitable when the adjusting magnet is arranged on the lateral latching element.

[0031] Regardless of how the latching element and the adjusting magnet are held on the base part or the operating lever, it can contribute to a space-saving design if at least one latching element is held on the base part and at least one adjusting magnet, in particular assigned to the latching element, is held on the operating lever, or vice versa. This applies in particular to at least one lateral latching element. Independently of this, it is particularly preferred in terms of construction if the latching element is held on the base part and the adjusting magnet is held on the operating lever.

[0032] Alternatively or additionally, in terms of a simple design, it can be provided that both the latching element and, in particular, the adjusting magnet assigned to the latching element are held on the base part or both are held on the operating lever. This can be structurally simple, in particular for the rear latching element. Independently of this, holding on the base part is particularly suitable in terms of a simple design. Alternatively or additionally, the adjusting magnet can be held simply and expediently on the base part or the operating lever via the latching element.

[0033] In order to achieve a flat design of the pivot lever on the side of the access control device facing the operating lever, the latching element can be arranged, in particular independently of its position, at least partially on the side of the contact plane, in which the pivot lever can rest against the access control device, facing away from the operating lever. This is particularly suitable for rear latching elements. Independently of this, a particularly flat design can be achieved if the latching element is not only partially, but at least substantially, arranged on the side of the contact plane facing away from the operating lever.

[0034] If the latching element is at least partially arranged on the side of the contact plane facing away from the operating lever, it can be simple in terms of function and structure for the operating lever to have at least one latching section which passes through the contact plane in the locking position of the operating lever. Then, in the locking position of the operating lever, at least one latching section and, in particular, the rear latching element in the latching position can form at least one form fit that prevents the operating lever from pivoting. In this regard, in terms of high safety against violent adjustment of the operating lever, it can be provided that the operating lever has at least two corresponding latching sections. Alternatively or additionally, at least one latching section of the operating lever can simply and at the same time expediently have a hook-shaped shape.

[0035] The latching element can be simply and conveniently configured to have a base body that is at least substantially L-shaped. This is particularly suitable for rear latching elements. Independently of this, it can additionally contribute to the simple and suitable configuration that the latching element can pivot between a latching position and a release position around a swing axis extending through the free end of the L leg of the base body. Alternatively or additionally, the latching element can have at least one latching section protruding laterally from the base body, which is used to form at least one form fit that prevents the operating lever from swinging. This can further simplify the configuration. Thus, in the latching position of the latching element, at least one latching section forms at least one form fit that prevents the operating lever from pivoting with the operating lever in the stop position. Independently of this, in terms of high safety against violent adjustment of the operating lever, it can be provided that the latching element has two laterally protruding latching sections. Thus, for the same reason, it is particularly preferred that the latching sections protrude from the base body in opposite directions. Alternatively or additionally, provision can be made structurally that at least one latching section is connected to the base body in the connecting region of the two L legs of the L-shaped base body.

[0036] Independently of the L-shaped base body, it is simple and expedient for the adjusting magnet to be at least partially accommodated in a magnet receptacle of a latching element, in particular corresponding to the adjusting magnet. This is particularly suitable for adjusting magnets corresponding to the rear latching element. Independently 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 be provided alternatively or additionally that the magnet receptacle is designed to match the adjusting magnet. Independently of the matching design, the magnet receptacle can also be arranged on the free end of the L leg of the L-shaped base body of the latching element for design reasons.

[0037] In order to provide a reliable form fit in a simple manner, when the operating lever is in the stop position and the latching element is in the latching position, the latching element can engage with at least one undercut of the operating lever from behind in a form-fitting manner and / or the operating lever can engage with at least one undercut of the latching element from behind in a form-fitting manner. This is particularly suitable for a rear latching element. Independently of this, with regard to safety against violent pivoting of the operating lever, it can be particularly provided that the latching element engages with two undercuts of the operating lever from behind and / or the operating lever engages with two undercuts of the latching element from behind. Alternatively or additionally, it can be expedient when at least one latching section of the latching element and / or the operating lever engages with at least one undercut from behind and / or forms at least one undercut.

[0038] Alternatively or in addition to engaging the undercut from behind, a reliable form fit can be achieved in a particularly space-saving manner in that, in the stop position of the operating lever, at least one latching element in the latching position is engaged in a latching receptacle of the operating lever or the base part in a form-fitting manner. This can be particularly suitable for at least one lateral latching element. Independently of this, for the case where at least one adjusting magnet, in particular, provided in the latching element, is held in a guide, it can be simple in terms of configuration that at least one latching receptacle is formed by at least one guide of the adjusting magnet. Alternatively or in addition, it can also be structurally preferred that the operating lever has at least one latching receptacle. Independently of this, it can be suitable that at least one latching element is arranged outside the latching receptacle in the release position, more precisely, at least one latching element is preferably arranged independently of the position of the operating lever.

[0039] In order to prevent the latching element from accidentally reaching the release position, at least one safety element can be provided, which is used to keep at least one latching element in the latching position. Thus, when the operating lever is in the stop position, at least one latching element can be kept in the latching position by at least one safety element. Independently of this, if at least one safety element is additionally configured to automatically adjust at least one latching element from the release position to the latching position, it is possible to prevent the latching element from being accidentally retained in the release position. Thus, at least one latching element can therefore automatically adjust from the release position to the latching position by at least one safety element. Independently of this, in the case of multiple latching elements, it can be suitable for the reasons already mentioned that the latching elements are respectively equipped with at least one safety element. Alternatively or additionally, the latching element is kept in the latching position, and / or the latching element is automatically adjusted from the release position to the latching position, which can be simply and appropriately caused by a safety force. Thus, for the same reason, it can be further provided that the safety force is a magnetic force, in particular a magnetic attraction force.

[0040] When the safety force is a magnetic force, at least one safety element can be suitably configured as a safety magnet, in particular a permanent magnet. Thus, at least one safety magnet can be formed by at least one adjusting magnet in a space-saving manner. This is particularly suitable when the safety magnet is arranged on the lateral latch element. Alternatively, at least one safety magnet and at least one adjusting magnet can be constructed as separate components. This can be particularly suitable when the safety magnet is arranged on the rear latch element due to structural reasons. Independently of this, it can be structurally suitable, in particular in the separate construction of the safety magnet, for at least one safety magnet to be retained on the latch element or to be retained in a fixed position on the base part. Here, for simplicity, at least one safety magnet can be retained in a magnet receiving portion, in particular a matching structure. Alternatively or additionally, the latch element can be provided with at least two safety magnets in order to increase the safety force. This can be particularly suitable for the rear latch element. Alternatively or additionally, one of the two safety magnets can be suitably retained on the latch element, while the other safety magnet therein can be retained in a fixed position on the base part.

[0041] In order to prevent the adjusting magnet from accidentally reaching the unlocked position, the swivel lever can have at least one retaining element, which is used to keep at least one adjusting magnet, especially provided on the lateral latching element, in the original position. Thus, when the adjusting magnet is not adjusted to the unlocked position by means of a key, the at least one adjusting magnet can therefore be kept in the original position by at least one retaining element. In order to prevent the adjusting magnet from accidentally staying in the unlocked position independently of this, at least one retaining element can also be constructed to automatically adjust the at least one adjusting magnet from the unlocked position to the original position. Thus, the at least one adjusting magnet can be automatically adjusted from the unlocked position to the original position by at least one retaining element. Independently of this, the retaining element is particularly suitable for such an adjusting magnet, which can be adjusted independently of the latching element, especially corresponding to the adjusting magnet. Alternatively or additionally, at least one retaining element can be appropriately constructed separately from at least one safety element. Independently of this, in the case of a plurality of adjusting magnets, it can be provided for simplicity that one retaining element corresponds to a plurality of adjusting magnets.

[0042] The holding of the adjusting magnet in the home position and / or the automatic adjustment of the adjusting magnet from the unlocked position into the home position can be easily and conveniently caused by a holding force. For the same reason, it can be further provided that the holding force is a magnetic holding force, in particular a magnetic attraction holding force. In particular, when the holding force is a magnetic force, it can be preferred that at least one holding element is composed of a ferromagnetic material. Alternatively or additionally, it can be functionally preferred that at least one holding element is composed of a non-permanent magnetic material. Independently of this, at least one holding element can be simply and conveniently configured as a plate, in particular a strip.

[0043] In order to simplify the pivoting of the operating lever from the operating position into the locking position, the at least one latching element can be automatically adjusted from the locking position into the release position when the operating lever is pivoted from the operating position into the locking position. The pivoting of the operating lever from the operating position into the locking position can then cause the at least one latching element to be adjusted from the locking position into the release position. Thus, the cumbersome individual adjustment of the at least one latching element from the locking position into the release position can be omitted. Independently of this, the automatic adjustment of the at least one latching element can be realized simply and reliably in a form-fitting manner.

[0044] If the operating lever has at least one sliding surface, the automatic adjustment of the latching element from the latching position to the release position can be realized in a simple configuration. Then, when the operating lever is pivoted from the operating position to the stop position, at least one sliding surface of the operating lever slides on at least one latching element, and the latching element is automatically adjusted from the latching position to the release position. Alternatively or additionally, in the same context, at least one latching element can have a sliding surface. Then, when the operating lever is pivoted from the operating position to the stop position, the sliding surface of at least one latching element slides on the operating lever, and the latching element is automatically adjusted from the latching position to the release position. Here, in terms of particularly reliable adjustment of the latching element, it can be provided that at least one sliding surface of the operating lever and the sliding surface of at least one latching element are constructed for sliding against each other. Independently of this, at least one sliding surface can be simply configured by chamfering. Alternatively or additionally, it may be expedient for at least one sliding surface of the operating lever to be arranged in a position in sliding contact with at least one latching element and / or for the sliding surface of at least one latching element to be arranged inclined, for example, at an angle of at least 30° and / or at most 60°, in particular at approximately 45°, relative to the direction in which the latching element in the latching position is released. The release direction may in principle in particular be understood as a direction in which the latching element can be adjusted from the latching position into the release position.

[0045] In order to facilitate the pivoting of the operating lever out of the stop position, the operating lever can be pivoted into the stop position against the reset force. Thus, the reset force can support the operating lever to pivot out of the stop position. Independently of this, the reset force can be provided in a simple manner by a spring element, for example in the form of a helical torsion spring.

[0046] In order to contribute to high security against unauthorized unlocking of the operating lever in addition to simple pivoting of the operating lever, in the locking position of the operating lever, a force can be exerted on at least one latching element in the latching position by a reset force, which force resists adjustment of the latching element to the release position. Here, it can be simple in design that the force resisting adjustment to the release position is caused by a force fit. Independently of this, it can be particularly simple in design that a force fit acts between at least one latching element and the operating lever and / or between at least one latching element and the base part.

[0047] It can contribute to the simple design of the bolt mechanism that the swivel lever has a key receiving portion, which is used to at least partially, in particular at least mainly, receive the key. Thus, for example, a rod-shaped key can be at least partially, in particular at least mainly, received in the key receiving portion in the use state, preferably inserted into the key receiving portion. Independently of this, it can contribute to the simple locking mechanism that the preferably elongated key receiving portion extends along the longitudinal axis of the operating lever and / or along the longitudinal axis of the base part. Alternatively or additionally, it can contribute to the compact design of the swivel lever that the key receiving portion is formed by the operating lever and / or the base part, wherein, for the same reason, it can be particularly provided that the key receiving portion is at least substantially formed by the operating lever. Independently of this, when the operating lever and the base part jointly form the key receiving portion, a particularly flat design of the swivel lever can be achieved. Alternatively or additionally, it can be provided for structural reasons that at least two of the adjusting magnets, in particular those provided on the lateral bolt element, and / or at least two retaining elements are arranged on opposite sides of the key receiving portion, in particular on opposite longitudinal sides.

[0048] In a first particularly preferred embodiment of the pivot lever system, the key receptacle of the pivot lever and the key have cross sections that match one another. This simplifies the precise arrangement of the key in the key receptacle when the operating lever is unlocked. For the same reason, it can further be provided that the matching cross sections have matching shaped elements that serve to orient the key in the key receptacle. This ensures that the key can only be inserted into the key receptacle in a given orientation, which simplifies handling. For simplicity, the shaped element can be designed as a shoulder.

[0049] Regardless of the matching cross-section of the key receiving portion and the key, the key can be configured as a universal key. Then, the key can suitably have at least one universal key magnet, which corresponds to the vacant position of the swing lever. Then, the universal key magnet therefore does not correspond to any adjustment magnet of the swing lever in particular. Instead of this, at least one universal key magnet can be used to unlock at least one other swing lever, which can be different from the swing lever of the aforementioned swing lever system in terms of the arrangement of at least one adjustment magnet. In this way, the key can be used to unlock differently encrypted swing levers. In this context, it is particularly provided that at least one universal key magnet is configured to adjust at least one adjustment magnet of at least one other swing lever from the original position to the unlocked position. Independently of this, at least one other swing lever can be part of the swing lever system in a suitable manner. However, this is not mandatory. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] In the drawings, the north pole of the magnet is denoted by "N", and the south pole of the magnet is denoted by "S".

[0060] Figure 1The pivot lever system 1 is shown in a three-dimensional illustration and comprises a pivot lever 2 with an operating lever 3, wherein the operating lever is in an operating position. In addition to the operating lever 3, the pivot lever 2 also has a base part 4. In this case, the operating lever 3 is pivotably held on the base part 4 by a rotating disk 5 so that the pivot lever 2 can be pivoted relative to the base part 4 about an operating axis AB and about a locking axis AA at least substantially perpendicular to the operating axis AB. The base part 4 has a groove-shaped lever receptacle 6 in which the operating lever 3 can be accommodated.

[0061] The operating lever 3 has two hook-shaped latching sections 7 on its back side corresponding to the base part 4, which protrude from the base body of the operating lever 3 toward the base part 4. Here, these latching sections 7 are respectively provided for passing through the notches 8 in the bottom 9 of the base part 4.

[0062] In addition to the swivel lever 2, the swivel lever system 1 also has a key 10 adapted to the swivel lever 2. The key 10, which is configured as a rod in the figure, has a plurality of permanent magnetic key magnets 11, which are different in their polarity. The key 10 is shown in the figure in a non-use state. In order to accommodate the key 10 in the use state, the swivel lever 2 has a key receiving portion 12, which in the illustrated and preferred swivel lever 2 is mainly formed by the operating lever 3 and partially by the base part 4. Here, the key receiving portion 12 currently extends along the longitudinal axis LBH of the operating lever 3 and the longitudinal axis LBT of the base part 4.

[0063] exist Figure 1 In the operating position shown, the operating lever 3 is swung out of the lever receptacle 6 so that the operating lever 3 can be pivoted about the operating axis AB relative to the base part 4. In order to lock the operating lever 3 on the base part 4, the operating lever 3 can be pivoted about the locking axis AA onto the base part 4 until it enters the locking position. Figure 2 The detent position is shown in .

[0064] Figure 2 The swivel lever 2 is shown in a three-dimensional diagram in a state where the operating lever 3 is in the locking position. The operating lever 3 is at least substantially accommodated in the lever accommodation portion 6 of the base part 4, so that the pivoting of the operating lever 3 about the operating axis AB is prevented in a form-fitting manner. The key accommodation portion 12 formed by the operating lever 3 and the base part 4 has a key opening 13 at its longitudinal end corresponding to the free end of the operating lever 3, through which the key 10 (not shown) can be inserted into the key accommodation portion 12.

[0065] Figure 3A-3B Along the Figure 2 The section plane IIIA-IIIA shown in FIG. Figure 3AThe two sectional views of the section plane IIIB-IIIB shown in FIG. 2 show the pivot lever 2, wherein the operating lever 3 is in the locking position and there is no key 10 at this time. The pivot lever 2 is fixed to the base part 4 by means of the base part 4. Figure 3A The access control device 14, not shown in the figure, has, for example, the form of a panel door and / or a panel shutter.

[0066] In the illustrated and in this respect preferred embodiment, the pivot lever 2 has eleven lateral latching elements 15, which are designed as steel pins in the figure and are arranged distributed along the longitudinal axis LBT of the base part 4 on opposite sides of the longitudinal axis LBT. The lateral latching elements 15 are held captively on the base part 4 in guides 16 of the base part 4. The lateral latching elements 15 can be moved in the associated guides 16 along their longitudinal axis LVE.

[0067] The lateral latching elements 15 are each provided with an adjusting magnet 17 made of a permanent magnetic material. The adjusting magnets 17 are held captively on the operating lever 3 in a guide 18 of the operating lever 3, wherein the adjusting magnets 17 can be moved in the guide 18 along the longitudinal axis LVE of the associated lateral latching element 15. By moving the adjusting magnets 17 outward, the lateral latching elements 15 are also moved outward in a form-fitting manner.

[0068] The operating lever 3 has a respective retaining element 19 on opposite longitudinal sides of the key receptacle 12 . The retaining elements 19 are designed as ferromagnetic strips which extend in the present case along the longitudinal axis LBH of the operating lever 3 and along the adjusting magnet 17 .

[0069] The lateral latching elements 15 are each arranged in a latching position. In the latching position, the latching elements 15 held on the base part 4 engage in a positively locking manner in a latching receptacle 20 of the operating lever 3, wherein the latching receptacle 20 is formed in the present case by a guide 18 for the adjusting magnet 17. In this way, the operating lever 3 is prevented from being pivoted out of the illustrated locking position and out of the lever receptacle 6 about the locking axis AA by the lateral latching elements 15 in a positively locking manner.

[0070] The adjusting magnets 17 assigned to the lateral latching elements 15 are each arranged in a home position. In this home position, the adjusting magnets 17 hold the lateral latching elements 15 in the latching position shown by the magnetic attraction interaction between the adjusting magnets 17 and the latching elements 15. This prevents the lateral latching elements 15 from accidentally reaching a position in which the latching elements 15 release the operating lever 3 from the stop position and pivot out of the lever receptacle 6. Therefore, in the illustrated and preferred embodiment, the adjusting magnets 17 also serve as the securing elements 21 of the lateral latching elements 15. The adjusting magnets 17 are again held in the illustrated home position by the magnetic attraction interaction with the ferromagnetic strips 19.

[0071] In the illustrated and preferred embodiment, a spring element 22, which is in the present case designed as a helical torsion spring, acts between the operating lever 3 and the rotary disk 5. A restoring force FR acts on the operating lever 3 via the spring element 22, which supports the pivoting of the operating lever 3 out of the lever receptacle 6 about the locking axis AA. The restoring force FR hereby respectively brings about a force fit between (on the one hand) the lateral latching element 15 and (on the other hand) the operating lever 3 and the base part 4, which counteracts a displacement of the respective latching element 15 out of the associated latching receptacle 20.

[0072] Figures 4A-4C Along the Figure 3A The two sectional views of the sectional planes IVA-IVA and IVB-IVB shown in FIG. 1 and the isometric view from obliquely below show a detail of the pivot lever 2 , wherein the operating lever 3 is in the locking position and there is no key at this time. For the sake of clarity, Figure 4C 2 shows only the operating lever 3 of the swivel lever 2 and the rear latching element 23 and the adapter element 24. The rear latching element 23, which is currently made of aluminum and / or zinc material by die casting, is arranged at least substantially on the side of the contact plane E facing away from the operating lever 3, in which the swivel lever 2 is in contact with the access control device 14. Here, the rear latching element 23 is held on the adapter element 24 in a pivotable manner about a swivel axis AS at least substantially parallel to the contact plane E. The rear latching element 23 is currently 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 fixed to the base part 4 by means of screws 26.

[0073] The rear latching element 23 has a substantially L-shaped base body 27 and two latching sections 28 protruding laterally from the L-shaped base body 27. Here, the pivot axis AS of the rear latching element 23 extends through the free end of one of the two L legs of the L-shaped base body 27. A magnet receptacle 29 is provided at the free end of the other of the two L legs of the L-shaped base body 27, in which an adjustment magnet 30 is accommodated, which is assigned to the rear latching element 23 and is made of a permanent magnetic material.

[0074] In addition to the adjusting magnet 30, a likewise permanent securing magnet 31 is held on the rear latching element 23 in a magnet receptacle 32 of the latching element 23. The securing magnet 31 held on the rear latching element 23 interacts with a permanent securing magnet 33, which is now held stationarily on the base part 4 via the adapter element 24 and is held in a magnet receptacle 34 of the adapter element 24.

[0075] The rear latching 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 held on the base part 4 by screws 36, wherein the access control device 14 is clamped between the base part 4 and the cover cap 35. In the illustrated and in this respect preferred embodiment, the pivot lever 2 is fixed to the access control device 14 in this way.

[0076] In order to prevent the penetration of large particles of dirt into the key receptacle 12 formed by the base part 4 and the operating 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 in this respect preferred embodiment, the protective flap 37 is pivotably held on the operating lever 3 between a position in which the key opening 13 is at least substantially closed and a position in which the key opening 13 is released.

[0077] The rear latching element 23 is arranged in the latching position. In this latching position, the latching sections 28 of the rear latching element 23 each engage from behind an undercut 38 of the operating lever 3. In this case, the undercut 38 of the operating lever 3 is formed in each case by one of the two hook-shaped latching sections 7 of the operating lever 3, which pass through the recess 8 of the base part 4 and through the contact plane E. The hook-shaped latching sections 7 of the operating lever 3 in turn each engage from behind an undercut 39 of one of the latching sections 28 of the rear latching element 23. In this way, the operating lever 3 is prevented from pivoting out of the illustrated locking position by the rear latching element 23 in a form-fitting manner.

[0078] By the magnetic attraction interaction between the securing magnet 31 held on the rear latching element 23 and the securing magnet 33 held on the adapter element 24, the latching element 23 is held in the latching position shown, and thus the adjusting magnet 30 held on the latching element 23 is also held in the original position shown. This prevents the rear latching element 23 from accidentally reaching a position in which it could release the pivoting of the operating lever 3. Figures 4A-4C The restoring force FR of the spring element 22 (not shown) additionally brings about a force fit between the hook-shaped latching section 7 of the actuating lever 3 and the latching section 28 of the rear latching element 23 , which counteracts a pivoting of the latching element 23 about the pivot axis AS.

[0079] In order to enable the operating lever 3 to Figure 3A-3B and Figures 4A-4C The locking position shown in the figure is pivoted about the locking axis AA into the operating position, and the pin-shaped key 10, which is not shown at present, can be pushed into the key receiving portion 12 through the key opening 13 and thus adjusted to the use state. Figure 4A The position shown in FIG. 1 , which at least substantially locks the key opening 13 , is pivoted in a form-fitting manner into a position that releases the key opening 13 .

[0080] Figure 5A-5B Along the Figure 2 The cross-sectional planes VA-VA and Figure 5A The two sectional views of the sectional plane VB-VB shown in FIG. 1 show the swivel lever system 1, wherein the operating lever 3 is in the locking position and the key 10 is in the use state. The key magnets 11 of the key 10 respectively correspond to one of the lateral latching elements 15 of the swivel lever 2 and to the corresponding adjustment magnets 17. Here, the magnetic repulsive interaction between the key magnet 11 and the adjustment magnet 17 is greater than the magnetic attractive interaction between the adjustment magnet 17 and the ferromagnetic holding element 19, so that the adjustment magnet 17 is respectively moved along the longitudinal axis LVE of the corresponding lateral latching element 15 from the original position ( Figure 3A-3B ) to the unlocked position.

[0081] By moving the adjustment magnet 17 provided on the lateral latching element 15 from the initial position ( Figure 3A-3B ) into the unlocked position, the lateral latching elements 15 are respectively moved along their longitudinal axis LVE from the latching position ( Figure 3A-3B ) into the release position. In the release position, the lateral latching elements 15 are arranged outside the latching receptacle 20 of the operating lever 3, so that the operating lever 3 is released by the lateral latching elements 15 to pivot out of the lever receptacle 6 about the locking axis AA.

[0082] The adjusting magnets 17 provided on the lateral latching elements 15 differ in their polarity. Currently, the magnetic poles of adjacent adjusting magnets 17 are oriented opposite to each other. However, this is not mandatory. Rather, the magnetic poles of the adjusting magnets 17 can be oriented arbitrarily and thus achieve any encryption.

[0083] When the key 10 is removed from the key receiving portion 12, the adjustment magnet 17 provided on the lateral latching element 15 automatically moves from the unlocking position shown in the direction of the retaining element 19 to the original position ( Figure 3A-3B Due to the magnetic attraction interaction between the adjustment magnet 17 and the lateral latching element 15, the movement of the adjustment magnet 17 causes the latching element 15 to automatically move from the release position shown to the latching position ( Figure 3A-3B ), in which latching position the latching element 15 engages in a latching receptacle 20 of the operating lever 3 .

[0084] The key 10 is currently configured as a universal key 10 and has a universal key magnet 40 in addition to the key magnet 11. In the illustrated and preferred embodiment, the universal key magnet 40 is configured identically to the key magnet 11 corresponding to the lateral latching element 15. However, in contrast to the key magnet 11, the universal key magnet 40 does not correspond to any latching element 15, 23 of the swing lever 2, and therefore also does not correspond to any adjusting magnet 17, 30. Instead, the universal key magnet 40 corresponds to the empty space 41 of the swing lever 2. Here, a guide 16 for the latching element and a guide 18 for the adjusting magnet are currently provided on the empty space 41. However, this is not mandatory. For example, the swing lever 2 can also be configured solid in the region of the empty space 41. By means of the universal key magnet 40 , at least one further pivot lever 2 can be unlocked, which in the position of the free space 41 has a latching element corresponding to the universal key magnet 40 and an adjusting magnet corresponding to the universal key magnet 40 .

[0085] In the illustrated and in this respect preferred embodiment, the cross section of the key 10 is designed to match the cross section of the key receptacle 12. In this case, 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 a given orientation.

[0086] Figure 6A-6B Along the Figure 5AThe two sectional views of the sectional planes VIA-VIA and VIB-VIB shown in the figure show a detail of the swivel lever system 1, wherein the operating lever 3 is in the locking position and the key 10 is in the use state. In addition to the key magnet 11 corresponding to the lateral latching element 15 and the associated adjustment magnet 17, the key 10 currently also has two key magnets 43 corresponding to the rear latching element 23 and the associated adjustment magnet 30. Here, the magnetic repulsive interaction between the key magnet 43 and the adjustment magnet 30 is greater than the magnetic attractive interaction between the two safety magnets 31, 33 corresponding to the rear latching element 23, so that the adjustment magnet 30 is moved around the swivel axis AS from the original position ( Figures 4A-4C ) is pivoted to the unlocked position.

[0087] By adjusting the magnet 30 from the original position ( Figures 4A-4C ) to the unlocked position, the rear latch element 23 also pivots around the swing axis AS from the latched position ( Figures 4A-4C ) into the release position. In the release position of the rear latching element 23, the mutual engagement from behind between the latching element 23 and the hook-shaped latching section 7 of the operating lever 3 is canceled, so that the operating lever 3 is released by the rear latching element 23 to pivot out of the lever receptacle 6 about the locking axis AA. When the key 10 is removed from the key receptacle 12, the rear latching element 23 automatically pivots from the shown unlocking position about the pivot axis AS into the latching position ( Figures 4A-4C ), in which the latching position the latching element 23 prevents the operating lever 3 from pivoting.

[0088] In order to prevent the rear latching element 23 from being able to reach a position in which the magnetic interaction between the two securing magnets 31, 33 is at least substantially eliminated, the latching element 23 in the shown release position with its laterally protruding latching section 28 rests against the longitudinal strut 25 of the adapter element 24. Thus, the adapter element 24 prevents the rear latching element 23 from being pivoted further about the pivot axis AS away from the securing magnet 33 held on the adapter element 24 in a form-fitting manner.

[0089] The operating lever 3 can be moved together with the key 10 inserted into the key receiving portion 12 about the locking axis AA from the lever receiving portion 6 and from the key receiving portion 12. Figure 5A-5B and Figure 6A-6B The detent position shown in FIG. is pivoted out of the detent position into, for example, Figure 1 in the operating position shown in .

[0090] Fig. 7A Along the Figure 3AThe sectional view of the section plane VIIA-VIIA shown in the figure shows a detail of the pivot lever 2 in the region of one of the lateral latching elements 15, wherein the operating lever 3 is in a position at least partially pivoted out of the lever receptacle 6 and without the key 10. The adjusting magnet 17 assigned to the lateral latching element 15 is arranged in the basic position and is held there by magnetic attraction interaction with the associated retaining element 19. The lateral latching element 15, which is freely movable along its longitudinal axis LVE in the associated guide 16, is arranged in the latching position.

[0091] The operating lever 3 has a sliding surface 44 below the guide 18 for the adjustment magnet 17, which is assigned to the lateral latching element 15 and has the form of a chamfer 44. In addition, in the illustrated and preferred embodiment, the lateral latching element 15 has a sliding surface 45 at its longitudinal end corresponding to the operating lever 3, which has the form of a chamfer 45 surrounding the longitudinal axis LVE of the latching element 15. The sliding surfaces 44, 45 are arranged obliquely with respect to the release direction RF of the latching element 15, in the present case at an angle of approximately 45°.

[0092] When the operating lever 3 is pivoted in the direction of the lever receiving portion 6, the sliding surface 44 of the operating lever 3 and the sliding surface 45 of the lateral latching element 15 slide against each other. As a result, the lateral latching element 15 moves from the latching position shown in the release direction RF to the release position ( Figure 5B ). This prevents the lateral latching element 15 from preventing the operating lever 3 from pivoting into the lever receiving portion 6. Thus, as long as the operating lever 3 is in the stop position ( Figure 3B ) and the latch receiving portion 20 is arranged in alignment with the lateral latch element 15, then the latch element 15 automatically moves from the release position ( Figure 5B ) to the latched position shown.

[0093] Figure 7B-7C Along the Figure 3A The sectional views of the sections VIIB-VIIB and VIIC-VIIC shown in the figure show a detail of the pivot lever 2, wherein the operating lever 3 is in a position at least partially pivoted out of the lever receptacle 6 and without the key 10. The rear latching element 23 is arranged in the latching position and is held there by the magnetic attraction interaction between the securing magnets 31, 33 assigned to the latching element 23.

[0094] In the illustrated and in this respect preferred embodiment, the hook-shaped latching section 7 of the operating lever 3 and the latching section 28 of the rear latching element 23 each have a chamfered sliding surface 46, 47. Here, these sliding surfaces 46, 47 are arranged obliquely to the release direction RF of the rear latching element 23, in the present case at an angle of approximately 45°.

[0095] When the operating lever 3 is pivoted in the direction of the lever receiving portion 6, the sliding surface 46 of the hook-shaped latching section 7 of the operating lever 3 slides on the sliding surface 47 of the latching section 28 of the rear latching element 23. As a result, the rear latching element 23 overcomes the magnetic attraction interaction between the securing magnets 31 and 33 and pivots from the latching position shown in the release direction RF to the release position ( Figure 6A-6B ), so that the hook-shaped latching section 7 of the operating lever 3 can pass the latching section 28 of the rear latching element 23. The rear latching element 23 is thus prevented from hindering the operating lever 3 from pivoting into the lever receiving portion 6. Thus, as long as the operating lever 3 is in the stop position ( Figure 4A-4B ), the rear latch element 23 automatically moves from the release position ( Figure 6A-6B ) is pivoted to the latched position shown.

[0096] Figure 8 The swivel lever system 1 is shown in a side view, with the operating lever 3 in the operating position. The operating lever 3 of the swivel lever 2 is connected to the locking device 48, which is designed as a rotary latch, in a rotationally fixed manner about the operating axis AB and is arranged on the side of the contact plane E opposite the operating lever 3. By pivoting the operating lever 3 about the operating axis AB, the locking device 48 can also be pivoted about the operating axis AB. In this way, the locking device 48 can be pivoted, for example, between a locking position, which prevents the access control device 14 from opening, and an open position, which allows the access control device 14 to open.
