Description

Technical Field

[0001] The invention relates to a lock, in particular a cam lock, having a lock housing, having a lock cylinder rotatably mounted in the lock housing, wherein the lock cylinder is configured at a first end accessible from the front of the lock for inserting a key, in particular a plug-in key, in a torque-transmitting manner, and wherein the lock has a locking element which prevents the lock cylinder from rotating in the lock housing between an open position and a locked position when the key is removed. The invention also relates to a key, in particular a plug-in key, for such a lock, and to a lock system, in particular a cam lock system, having such a lock and such a key. Background Art

[0002] Locks such as cam locks are used in the prior art as industrial accessories, for example, for locking thin-walled panel doors. Simple cam locks have a lock profile on the lock cylinder, for example in the form of a quadrilateral or quadrilateral recess, for a key socket with a matching key profile, for example a plug-in key socket with a quadrilateral hollow profile or a quadrilateral profile, so that high torques can be transmitted from the plug-in key to the lock cylinder and thus to the rotating tongue. In this way, when the cam lock is opened or closed, the usually relatively high friction between the rotating tongue and the locking surface of the frame (surrounding the panel door) engaged by the rotating tongue from behind can be overcome. The disadvantage of such cam locks is that the security against unauthorized manipulation is relatively low, because such cam locks can be opened or closed relatively easily, for example using pliers, even without a matching plug-in key.

[0003] Furthermore, cam locks are known from the prior art in which conventional cylinder locks are integrated or in their lock core. Conventional cylinder locks of this type have a lock core with a key channel, wherein a movable locking element, such as a locking plate (for a plate-shaped cylinder lock), a locking disk (for a disk-shaped cylinder lock) or a locking pin (for a pin-shaped cylinder lock), blocks the rotation of the lock core in the lock housing if the locking element has not been mechanically moved into a specific position by the key profile of a matching key inserted into the key channel. This achieves a high level of security against unauthorized manipulation. However, conventional cylinder locks are more sensitive than plug-in key locks and are therefore not robust under harsh environmental conditions or require a lock cover to prevent dust and dirt from contaminating the delicate key channel or the movable locking element, which complicates the operation of the lock. Furthermore, with conventional cylinder lock keys, only very small torques can be transmitted due to the small leverage of the cylinder lock keys and the fine mechanical structure of conventional cylinder locks, which limits their use in cam locks that, as mentioned above, partially require high torques for opening and closing.

[0004] In order to be able to transmit high torques even with conventional cylinder locks, it is also known to provide, in addition to the cylinder lock, a separate rotary handle for unlocking, which is used to open or lock the cam lock. However, such cam locks have the disadvantage of increased operational complexity and require significantly more structural space. Summary of the invention

[0005] Against this background, the object of the present invention is to provide a lock, in particular a cam lock, a key for such a lock, and a lock system which overcome at least one or more of the above-mentioned disadvantages of the prior art.

[0006] According to the present invention, the above-mentioned object is solved by a lock, in particular a cam lock, which has a lock housing and a lock core rotatably supported in the lock housing, wherein the lock core is constructed at a first end that can be reached from the front of the lock to allow a key, in particular a plug-in key, to be inserted in order to transmit torque, and wherein the lock has a locking member that prevents the lock core from rotating in the lock housing between an open position and a locked position when the key is pulled out, wherein the locking member is constructed to release the lock core from rotating in the lock housing between an open position and a locked position when a key, in particular a plug-in key, having a given magnetic structure is inserted into the first end of the lock core.

[0007] In this way, a robust and compact lock, in particular a cam lock, is provided, on whose lock cylinder preferably a high or relatively high torque can be transmitted by inserting and turning the key, and which at the same time provides a certain basic security against the lock being opened or locked without a matching key.

[0008] The lock can be a cam lock in particular. In this case, the lock cylinder preferably carries a rotary tongue at the second end. The rotary tongue can be connected to the lock cylinder in particular in a detachable manner. With the lock, preferably high or relatively high torques can then be transmitted to the rotary tongue in order to lock the rotary tongue, for example, behind the mating surface or to move it out of a locked position behind the mating surface.

[0009] It is also conceivable that the lock is a rod lock, for example a rod lock for a door. In this case, the second end of the lock cylinder is preferably coupled to one or more rods in such a way that a rotational movement of the lock cylinder is converted into a translational movement of the one or more rods. For example, the lock cylinder can carry a gear on the second end, which meshes with a counterpart part of the rod of the rod lock, for example a rack part.

[0010] It is also conceivable that the lock is an axial lock. In this case, a profile that can be moved in the axial direction can be provided on the second end of the lock core, for example, which can be moved into a matching profile on the frame for locking and / or moved out of the matching profile for unlocking. It is also conceivable that the second end of the lock core carries a profile, for example a threaded profile or a bayonet profile, which can be rotated into a matching profile on the frame for locking and / or rotated out of the matching profile for unlocking. Combinations of these designs are also conceivable.

[0011] It is also conceivable that the lock is designed in the form of a profiled cylinder. For this purpose, the lock housing can in particular have the form of a profiled cylinder. This makes it possible to use the lock instead of a conventional cylindrical lock, for example a sheet-shaped cylindrical lock, a disk-shaped cylindrical lock or a pin-shaped cylindrical lock. In particular, in this way the lock can be easily installed in a locking device for a profiled cylinder. Such a profiled cylinder-shaped lock preferably has a locking projection connected to the lock core in a rotationally fixed manner.

[0012] Because the locking member is constructed to release the rotation of the lock cylinder in the lock housing between an open position and a locked position when a key with a predetermined magnetic structure is inserted onto the first end of the lock cylinder, a magnetic unlocking function is provided, so that the key contour and the corresponding lock contour of the lock cylinder can preferably be optimized geometrically and mechanically for transmitting high torques, for example, be constructed more robustly.

[0013] In contrast, in conventional cylinder lock systems, the shape of the cylinder lock-key and the key channel of the cylinder lock that receives the key are mechanically complex in order to achieve the mechanical unlocking function, which results in only very small torque being able to be transmitted.

[0014] The lock cylinder is configured to insert a sleeve for the key to transfer torque on the first end that can be approached from the front side of the lock. In this way, when the locking member releases the rotation of the lock cylinder, the lock cylinder can be operated by the key of the sleeve matching.

[0015] The first end of the lock cylinder is preferably designed in particular such that a matching key can be inserted onto the first end of the lock cylinder in a form-fitting manner, thereby enabling a torque to be transmitted from the key to the lock cylinder about the rotation axis of the lock cylinder. In this way, the lock cylinder can be operated by the key. Inserting the key can also include inserting a key profile, for example a protruding part of a polygonal profile, of the key into a matching recess on the first end of the lock cylinder.

[0016] The locking members are constructed in such a way that they prevent the lock cylinder from rotating between the open position and the locked position in the lock housing when the key is pulled out. The locking members can be constructed, for example, to prevent the lock cylinder from rotating from the open position to the locked position in the lock housing when the key is pulled out. Additionally or alternatively, the locking members can be constructed, for example, to prevent the lock cylinder from rotating from the locked position to the open position in the lock housing when the key is pulled out. Although it is conceivable, it is not necessary to prevent the lock cylinder from rotating in the lock housing when the key is pulled out. In particular, such a design can be considered, in which the lock cylinder can also move from an intermediate position between the open position and the locked position to the open position or the locked position when the key is pulled out, and the locking members are locked only when the open position and / or the locked position are reached.

[0017] The locking element is configured to release the rotation of the lock cylinder between the open position and the locked position in the lock housing when a key having a predetermined magnet structure is inserted onto the first end of the lock cylinder. Therefore, the locking element is particularly configured to interact magnetically with the predetermined magnet structure, and the magnetic interaction causes the rotation of the lock cylinder to be released.

[0018] The lock is magnetically encrypted by matching the locking element with a given magnet structure of the key. Therefore, it is required to operate the lock with a matching key having a given magnet structure, but operating the lock with a key without a magnet structure, or with a magnet structure different from the given magnet structure, is only possible in a limited manner, for example, only in an intermediate position between the open position and the locked position, or not at all. Therefore, the given magnet structure determines the construction of the lock. Although the magnet structure itself is not part of the lock. However, the locking element of the lock is specifically matched to the given magnet structure, so that the matching key with the given magnet structure of the plug sleeve causes the locking element to release the rotation of the lock cylinder.

[0019] According to the invention, the above-mentioned object is also solved by a key, in particular a plug-in key, in particular for the above-mentioned lock or an embodiment of the lock. The key has a handle part and a plug-in part, which can also be constructed in one piece. The plug-in part has a key profile, in particular a polygonal profile, for plugging onto a lock cylinder of a lock, in particular a lock cylinder of the lock or an embodiment of the lock described above, in order to transmit torque. In addition, the key has a magnetic structure on the plug-in part, which is in particular used for magnetic interaction with a locking part of a lock, in particular a locking part of the lock or an embodiment of the lock described above.

[0020] The key is in particular a plug-in key, for example a polygonal key. The key can in particular have an outer contour and / or an inner contour, for example a polygonal contour, with which the key can be plugged onto a corresponding matching contour, in particular an inner contour and / or an outer contour, of a lock. An example of a plug-in key with an outer contour is a key with an outer quadrilateral contour. An example of a plug-in key with an inner contour is a key with an inner quadrilateral contour. It is also conceivable that the key has not only an outer contour but also an inner contour.

[0021] Furthermore, according to the invention, the aforementioned object is achieved by a lock system, in particular a cam lock system, which has the aforementioned lock or an embodiment of the lock and a key matching the lock, in particular the aforementioned key or an embodiment of the key.

[0022] The key of the lock system is a key that matches the lock of the lock system. For this purpose, the key and the lock are matched to each other in particular such that the lock cylinder is configured to be inserted on the first end for the key to transmit torque, and the locking element of the cam lock is configured to release the rotation of the lock cylinder in the lock housing between the open position and the locked position when the key is inserted on the first end of the lock cylinder. In particular, the magnet structure of the key is a given magnet structure, and the locking element is configured to release the rotation of the lock cylinder in the lock housing between the open position and the locked position when the key with the given magnet structure is inserted on the first end of the lock cylinder.

[0023] In the following, different embodiments of locks, keys and lock systems will be described, wherein the various embodiments are respectively applicable to locks, keys and lock systems independently of one another. In addition, the various embodiments can be combined with one another as desired.

[0024] In one embodiment, the lock cylinder has a lock profile, in particular a polygonal profile, at a first end for inserting a key, preferably a plug-in key, in particular a polygonal key, in a torque-transmitting manner. This lock profile can preferably transmit high torques or relatively high torques when inserting a plug-in key with a matching key profile. In addition, this lock profile for a plug-in key is very strong compared to the key channel of a conventional cylindrical lock system, in particular under harsh environmental conditions such as dust. The lock profile can in particular have one or more recesses and / or one or more projections.

[0025] The lock profile of lock cylinder is arranged to insert the sleeve of the insert key to transmit torque. Accordingly, the lock profile is especially constructed like this, so that when the key assigned is inserted, the lock profile and the key profile of this key form a shape fit to transmit torque.

[0026] The lock profile can for example have a recess, for example a polygonal recess, for accommodating a mating projection, for example a polygonal projection, of the key profile of the assigned key. In addition, the lock profile can for example have a projection, for example a polygonal projection, for being accommodated in a mating recess, for example a polygonal recess, of the key profile of the assigned key.

[0027] The lock cylinder can also have a profile with a lock contour, in particular an outer contour, wherein the profile can protrude, for example laterally, relative to the lock housing at a first end. The key can correspondingly have a key contour, in particular an inner contour, matching the lock contour.

[0028] Preferably, the profile is designed to be flat and is limited by the outer contour of the edge, which forms the lock profile. This allows the lock profile to be designed in a very flat manner. In this way, for example, it is prevented that the user gets hooked on the protruding part of the lock profile. In addition, in this way, there are fewer points of action for manipulation.

[0029] Accordingly, the key can preferably have an inner contour which defines a flatly constructed region in which, for example, a magnet structure or one or more magnets of the magnet structure can be arranged. In this way, a sturdy key with a flat structure can be provided.

[0030] For example, the lock profile of the outer contour and / or the key profile of the inner contour can also be configured in a rounded shape, for example, preferably in an elliptical shape. In this way, the manipulation safety of the lock is improved, because there are fewer points of action for external tools, for example pliers, due to the rounded shape of the lock profile.

[0031] The lock contour and / or the key contour is preferably designed asymmetrically in such a way that the lock contour allows a key sleeve with a corresponding key contour only in one direction.

[0032] In one embodiment, a given magnet structure includes a given number of magnets, each of which has a given position. In another embodiment, a given magnet structure includes a given number of magnets, each of which has a given position and a given magnetic pole direction. Preferably, the magnet structure includes two or more magnets, each of which has a given position and optionally has a given magnetic pole direction. Further preferably, at least two magnets of the magnet structure have different magnetic pole directions, preferably have magnetic pole directions that are antiparallel to each other. In addition, the two magnets of the magnet structure can have corresponding magnetic pole directions, which are oriented at an angle to each other, for example, oriented at right angles. In the corresponding embodiment of the key, the magnet structure includes one or more magnets arranged in corresponding positions, wherein preferably, at least two magnets have different magnetic pole directions, particularly preferably have magnetic pole directions oriented antiparallel to each other.

[0033] By specifying a specific number of magnets for the magnet structure, which have a respective specified position and optionally a specified magnetic pole direction, the security of the lock against unauthorized manipulation can be increased. In particular, in this way, different magnet structures can be realized in geometrically identical keys, so that the key can be magnetically encrypted for the associated lock, so that the associated lock can be unlocked with the associated key, but not a lock that requires a key that is magnetically encrypted in a different way.

[0034] In one embodiment, the locking member comprises a locking element, which is movably supported between a locking position, in which the locking element prevents the rotation of the lock cylinder in the lock housing between the open position and the closed position, and a release position, in which the locking element releases the rotation of the lock cylinder in the lock housing between the open position and the closed position. In this way, the rotation of the lock cylinder can be selectively locked or released in a simple and reliable manner. Preferably, the locking element is configured to interact with the lock housing and the lock cylinder in a form-fitting manner in the closed position so that the rotation of the lock cylinder in the lock housing is prevented.

[0035] Preferably, the locking member includes a plurality of locking elements, which are movably supported between corresponding locking positions and corresponding release positions, in which the locking elements prevent the lock core from rotating in the lock housing between the open position and the locked position, and in the release position, the locking elements release the lock core from rotating in the lock housing between the open position and the locked position.

[0036] The locking element or elements may be mounted, for example, so as to be displaceable in the axial direction and / or in the radial direction relative to the rotation axis of the lock cylinder.

[0037] Preferably, not only one or more axially displaceable locking elements are provided, but also one or more radially displaceable locking elements are provided. In this way, good vibration resistance of the locking device is achieved, and also increased anti-manipulation safety is achieved.

[0038] In one embodiment, the lock core has a receptacle in which the locking element is movably mounted. In the case of a plurality of locking elements, the lock core preferably has a plurality of receptacles in which the locking elements are each movably mounted. In this way, a particularly compact design of the lock can be achieved. The receptacle can be formed, for example, by a blind hole or a through hole in the lock core or by an edge-side receptacle which is formed at least partially by the lock core.

[0039] In another embodiment, the lock housing has a receptacle in which the locking element is movably supported. In the case of a plurality of locking elements, the lock housing preferably has a plurality of receptacles in which the locking elements are each movably supported. In this way, a particularly robust design of the lock can be achieved.

[0040] In addition, the locking element can also be movably supported in a receptacle formed by the lock cylinder and the lock housing. This is conceivable, for example, for a multi-part locking element.

[0041] If one or more receptacles are arranged in the lock housing, one or more associated recesses are preferably provided in the lock core, into which the locking element sinks in the locked position and thereby prevents a rotational movement between the lock core and the lock housing. If one or more receptacles are arranged in the lock core, one or more associated recesses are preferably provided in the lock housing, into which the locking element sinks in the locked position and thereby prevents a rotational movement between the lock core and the lock housing.

[0042] In one embodiment, the locking part comprises a plurality of locking elements, which are supported in corresponding receptacles arranged around the rotation axis of the lock core in the lock housing and / or the lock core, and which engage in respectively provided recesses in the lock core and / or the lock housing in the locked position. Preferably, at least two, preferably all, of the receptacles and / or provided recesses arranged around the rotation axis of the lock core have different distances relative to the rotation axis of the lock core. In this way, it is possible to prevent the locking element arranged in the receptacle from sinking into a recess different from the recess corresponding to the receptacle when the lock core rotates, and to prevent the rotational movement between the lock core and the lock housing.

[0043] The locking part, in particular one or more locking elements, is preferably arranged spaced apart from the lock contour, preferably so that when the key is inserted on the first end of the lock cylinder, the locking part, in particular one or more locking elements, does not come into direct contact with the inserted key. Preferably, one or more receptacles and / or the provided recesses are spaced apart from the lock contour.

[0044] In one embodiment, the lock has a retaining element which is designed to retain the locking element in the locked position when the key is removed, in particular by a magnetic interaction between the retaining element and the locking element. In this way, the vibration safety of the lock is increased, so that even in the presence of mechanical shocks or vibrations, the locking element is reliably retained in the locked position when the key is removed, and thus prevents the lock from being opened or locked when the key is removed. In the case of a plurality of locking elements, the retaining element can preferably be designed to retain the plurality of locking elements in the locked position when the key is removed, by a magnetic interaction between the retaining element and the locking element.

[0045] The magnetic interaction between the holding element and one or more locking elements is preferably a magnetic attraction interaction. However, it is also conceivable that the magnetic interaction between the holding element and one or more locking elements is a magnetic repulsion interaction.

[0046] For example, the locking element can be a magnet or include a magnet, and the retaining element can also be a magnet or consist of a ferromagnetic material, for example the retaining element is designed as a ferromagnetic metal plate, such as a steel plate, or as a ferromagnetic pin, such as a steel pin.

[0047] In one embodiment, the locking element is configured to move into a release position when a key having a given magnetic structure is inserted onto the first end of the lock cylinder, more specifically, the locking element moves into the release position by magnetic interaction, in particular magnetic repulsion, between the locking element and the magnetic structure. In the case of a plurality of locking elements, the plurality of locking elements are preferably configured to move into a release position when a key having a given magnetic structure is inserted onto the first end of the lock cylinder, more specifically, the locking element moves into the release position by magnetic interaction, in particular magnetic repulsion, between the locking element and the magnetic structure. Unlocking by means of magnetic repulsion between the magnetic structure and one or more locking elements can achieve a reliable and smooth unlocking mechanism.

[0048] Preferably, the magnet arrangement has an associated magnet for each locking element, particularly preferably an associated corresponding magnet.

[0049] In one embodiment, the locking element is a magnet or comprises a magnet. In the case of a plurality of locking elements, at least one of them, preferably a plurality of locking elements, is a magnet or comprises a magnet. In this way, the locking element can be held in the locked position when the key is pulled out, for example by magnetic attraction interaction with a provided holding element. In addition, in this way, when the key is inserted onto the first end of the lock cylinder, the locking element can be moved into the release position, for example by magnetic repulsion interaction with the magnet of the magnet structure of the key.

[0050] The locking element can especially have a magnet and a sleeve, especially a metal sleeve, that encapsulates the magnet. In this way, when the lock cylinder is prevented from rotating in the lock housing, a greater shear resistance of the locking element is achieved, thereby improving the durability of the lock.

[0051] The locking element can also be constructed in multiple parts and, for example, comprise a magnet and a steel pin magnetically connected to the magnet, wherein the steel pin causes a rotation of the lock cylinder in the lock housing in the locked position. In this way, the durability of the lock can also be increased.

[0052] In one embodiment, the lock comprises a contact surface structure for a given magnet structure to abut, and the locking element is arranged and configured in such a way that when the given magnet structure abuts against the contact surface structure, in particular in a given orientation, the locking element releases the rotation of the lock cylinder in the lock housing between the open position and the locked position. In this way, the operation of the lock is made easier, because the user can check the correct position of the key on the lock based on the abutment on the contact surface structure. In addition, by abutting the magnet structure against the abutment surface structure, the distance between the magnet structure and the locking element can be kept as small as possible, so as to enhance the magnetic interaction between the magnet structure and the locking element.

[0053] The contact surface structure may in particular have one or more contact surfaces, which are provided for contacting one or more magnets of the magnet structure. The contact surface structure is in particular arranged such that the magnet structure contacts the contact surface structure when the key is inserted. The one or more contact surfaces of the contact surface structure may in particular be arranged on the first end of the lock cylinder and / or on the lock housing.

[0054] If the locking part includes one or more locking elements, these locking elements are preferably arranged in the area of ​​one or more abutment surfaces of the abutment surface structure, so that when the magnetic structure is abutted, a magnetic interaction is generated between the magnetic structure and the locking element, and the locking element is moved into the release position through this magnetic interaction.

[0055] In one embodiment, the contact surface structure is arranged completely or at least partially separated from the lock contour, for example, the contact surface structure is arranged radially outwardly or inwardly offset relative to the lock contour with respect to the rotation axis of the lock cylinder. In a corresponding embodiment of the key, the magnet structure is arranged completely or at least partially outside the key contour. In this way, the unlocking function can be structurally separated from the torque transmission function, thereby achieving a more robust structure of the lock and key.

[0056] In one embodiment, the contact surface structure is at least partially arranged on the lock contour, preferably on the inner surface of the receiving portion of the lock contour. In a corresponding embodiment of the key, the magnet structure is at least partially arranged on the key contour. In this way, the lock can be better protected from being manipulated by external magnets.

[0057] In one embodiment, the lock cylinder is constructed in multiple parts and has a core piece arranged in the inner passage of the lock housing and a profile piece having a lock profile, wherein the core piece and the profile piece are connected to each other in a rotationally fixed manner. For this purpose, the core piece and the profile piece can, for example, have mutually matching profiles with which the core piece and the profile piece engage with each other in a form-fitting manner. The core piece and the profile piece can, for example, be held together by pins or bolts, for example by means of a bolt extending through the core piece and screwed into the inner contour of the profile piece.

[0058] By means of a multi-part design of the lock cylinder, in particular with a core part and a profile part, it is possible, for example, to provide the lock with a desired lock profile as required by selecting a suitable profile part from a plurality of different types of profile parts.

[0059] In one embodiment, the key has a wall thickness of at least 4 mm. Preferably, the key profile of the key has a wall thickness of at least 4 mm. In this way, higher torques can be transmitted with the key. The lock profile is preferably configured accordingly for inserting a key profile having a wall thickness of at least 4 mm.

[0060] The key is preferably at least partially made of metal, which allows high torques to be transmitted. The grip of the key preferably extends at least 2 cm, more preferably at least 3 cm, and particularly preferably at least 4 cm transversely to the rotation axis of the key provided for operating the key. In this way, the user can more easily transmit higher torques to the key and thus to the lock cylinder when the key is inserted into the lock cylinder.

[0061] Further features and advantages of the lock, the key and the lock system emerge from the following description of embodiments with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0072] The cam lock 20 has a lock housing 22 with an internal passage 24 in which a lock cylinder 26 is supported rotatably about an axis A. The lock housing 22 has a flange 30 on a front face 28 of the cam lock 20 , from which a housing body 32 with an external thread 34 extends.

[0073] For assembly, the cam lock 20 can be inserted into the opening 90 of the thin panel door 92 with the housing body 32 as a guide until the flange 30 abuts against the panel door 92. The nut 36 can then be screwed onto the external thread 34 from behind to secure the cam lock 20 to the panel door 92.

[0074] The lock cylinder 26 is designed at a first end 38 accessible from the front side 28 for torque-transmitting insertion of the key 2. For this purpose, the lock cylinder 26 has at its first end 38 a lock contour 40 that matches the key contour 8 and is designed here as a polygonal contour, i.e., a quadrilateral recess, for accommodating the key contour 8 designed as a quadrilateral projection.

[0075] At a second end 42 of the lock cylinder 26, which is opposite the first end 38, the lock cylinder 26 carries a rotary tongue 44, which is connected to the lock cylinder 26 in a rotationally fixed manner via matching contours 46, 48 on the lock cylinder 26 and the rotary tongue 44 and is fixed by means of a screw 50. By inserting and turning the key 2, the lock cylinder 26 and thus the rotary tongue 44 can be rotated between an open position and a locked position. Figure 1g The locked position is shown in the installed state, in which the rotary tongue 44 engages the locking surface 94 of the frame 96 (surrounding the panel door 92) from behind and in this way locks the panel door 92. When the lock cylinder 26 is rotated, for example, by 90°, the lock cylinder 26 or the rotary tongue 44 reaches an open position, in which the rotary tongue 44 no longer engages the locking surface 94 from behind, so that the panel door 92 can be opened.

[0076] The cam lock 20 also has a locking member 52, which prevents the lock cylinder 26 from rotating between the unlocked position and the locked position in the lock housing 22 when the key 2 is removed. Figure 1a-1g In the example of FIG. 5 , the locking member 52 includes a plurality of locking elements 54, which are movably supported in receiving portions 56 on the respective edge sides of the lock cylinder 26. The locking elements 54 can be in the corresponding receiving portions 56 in the locking position (see Figure 1e ) and release position (see Figure 1f ). In the locked position ( Figure 1e), the locking element 54 engages in a corresponding recess 58 of a shape element 60 fixed to the lock housing 22 and thereby prevents the lock cylinder 26 from rotating in the lock housing 22 between the open position and the closed position. Figure 1f ), the locking element 54 is pulled back into the receiving portion 56 and does not engage with the recess 58, so that the locking element 54 releases the rotation of the lock cylinder 26 in the lock housing 22 between the open position and the closed position in this released position.

[0077] The locking member 52 is configured to release the rotation of the lock cylinder 26 between the open position and the locked position in the lock housing 22 when the key 2 having the magnet structure 12 is inserted onto the first end 38 of the lock cylinder 26. This is achieved in the cam lock 20 in the following manner, that is, the locking element 54 is configured as a magnet, and the number, position and magnetic pole direction of the magnets 14 of the magnet structure 12 of the key 2 are matched with the number, position and magnetic pole direction of the locking element 54 so that when the key 2 is inserted, the magnets 14 of the magnet structure 12 and the corresponding locking elements 54 with the same magnetic poles are respectively opposite to each other, so that a magnetic repulsion force acts on the locking element 54, which moves the locking element 54 out of the corresponding recess 58 and into the released position.

[0078] In this way, the cam lock 20 can be unlocked using a key 2 with a given magnet structure that matches it, while a key with a different magnet structure of the same type with respect to the key profile 8 will not cause the cam lock 20 to be unlocked. Therefore, the cam lock 20 and the key 2 are magnetically encrypted by the number, position and magnetic pole direction of the magnets 14 of the magnet structure 12, and the number, position and magnetic pole direction of the locking elements 54 that match it.

[0079] In order to hold the locking element 54 in the locked position when the key 2 is pulled out, a holding element 62 in the form of a ferromagnetic plate, for example a steel plate, is provided on the lock housing 22, which has a central opening 63 for the lock contour 40. The locking element 54 is held in the recess 58 by the magnetic attraction between the locking element 54 and the holding element 62. The strength of the magnet 14 and the locking element 54 configured as a magnet are matched so that when the key 2 is inserted, the magnetic attraction between the locking element 54 and the holding element 62 is overcome by the magnetic repulsion between the magnet 14 and the locking element 54, and the locking element 54 is moved into the release position.

[0080] In order to increase the durability of the cam lock 20 , magnets each surrounded by a steel sleeve may also be used as locking elements 54 in one possible embodiment.

[0081] A mark 66 is provided on the annular end side 64 of the lock housing 22 (which in the present example is formed by one side of the retaining element 62), which matches the mark 16 on the key 2 to indicate to the user the correct direction of the key 2 relative to the cam lock 20, thereby correctly orienting the magnet structure 12 relative to the locking element 54.

[0082] The end face 64 in the cam lock 20 simultaneously forms an abutment surface 67 of an abutment surface structure 68 of the cam lock 20, which is provided for abutting the magnet structure 12 in the direction given by the reference numerals 16 and 66. The abutment surface 67 is arranged separately from the lock contour 40, more precisely, it is arranged radially outside the lock contour 40 with respect to the rotation axis A. Correspondingly, the locking element 54 is also arranged separately from the lock contour 40, that is, it is arranged in the region of the abutment surface 67.

[0083] In this way, the unlocking function caused by the magnetic interaction between the magnet structure 12 and the locking element 54 when the magnet structure 12 is in contact with the contact surface 67 is spatially separated from the torque transmission function caused by the form-fitting interaction between the key contour 8 and the lock contour 40. As a result, the lock contour 40 and the key contour 8 can be optimized for torque transmission and in particular designed to be more robust without the need to directly integrate movable or delicate components, such as magnets and locking elements, into the lock contour 40 and the key contour 8.

[0084] Figure 2a-2g A second embodiment of a lock, key and lock system is shown. Figure 2a The key 102 and the lock 120 are shown in three dimensions. Figure 2b Corresponding to Figure 2e The key 102 and the lock 120 are shown in a partially cutaway three-dimensional illustration at the section marked with "IIc" in FIG. Figure 2c and Figure 2d Based on Figure 2e The cross-sectional view of the section marked with "IIc" in FIG. 1 shows the key 102 and the lock 120, and more specifically, shows the key 102 before it is inserted ( Figure 2c ) and after inserting the key 102 ( Figure 2d ) view. Figure 2e shows the corresponding Figure 2c A cross-sectional view of the section indicated by "Ⅱe". Figure 2f shows the corresponding Figure 2d A sectional view of the section indicated by "Ⅱf". Figure 2g Shows the corresponding Figure 2f A cross-sectional view of the lock cylinder after the lock cylinder is rotated 45°.

[0085] The key 102 and the lock 120 together form a lock system 180 .

[0086] In this example, the lock 120 is configured as a cam lock, and the lock system 180 is correspondingly configured as a cam lock system. Alternatively, the lock 120 can also be configured as a rod lock or an axial lock, and the lock system 180 can be correspondingly configured as a rod lock system or an axial lock system.

[0087] The key 102 is also a plug-in key with a handle 104 and a plug-in portion 106, which are integrally constructed in this example. The plug-in portion 106 has a key profile 108, which is constructed as a polygonal profile, i.e. a cross-shaped protrusion in this example. However, other key profiles 108 are also conceivable. In the key 102, a magnet structure 112 with a plurality of magnets 114 is arranged on the key profile 108. The magnets 114 are embedded in four radial blind holes 109 of the key profile 108. The magnets 114 have a given magnetic pole direction, which is partially marked with "N" (magnetic north pole) and "S" (magnetic south pole) in the accompanying drawings.

[0088] The cam lock 120 has a lock housing 122 with an internal passage 124 in which a lock cylinder 126 is supported rotatably about an axis B. The lock housing 122 has a flange 130 on a front face 128 of the cam lock 120, from which a housing body 132 with an external thread 134 extends. The assembly of the cam lock 120 can be carried out as described for the cam lock 20.

[0089] The lock cylinder 126 is configured at a first end 138 accessible from the front side 128 for torque-transmitting insertion of the key 102. For this purpose, the lock cylinder 126 has a lock contour 140 at its first end 138 that matches the key contour 108, which is configured here as a cross-shaped recess for accommodating the key contour 108 configured as a cross-shaped projection.

[0090] At a second end 142 of the lock core 126, which is opposite the first end 138, the lock core 126 carries a rotary tongue 144, which is connected to the lock core 126 in a rotationally fixed manner via mating contours 146, 148 on the lock core 126 and the rotary tongue 144 and is fixed by means of a screw 150. When the key 102 is inserted, the lock core 126 and thus the rotary tongue 144 are rotated between the open position and the closed position in a manner similar to that described above for the cam lock 20.

[0091] The cam lock 120 also has a locking member 152 that prevents the lock cylinder 126 from rotating between the unlocked position and the locked position in the lock housing 122 when the key 102 is removed. Figure 2a-2gIn the example of , the locking member 152 includes a plurality of locking elements 154, which are supported in a receiving portion 156 formed by the lock housing 122 and the lock core 126 so as to be radially movable relative to the rotation axis B. The receiving portion 156 accordingly includes a first portion 156a formed by the lock housing 122 and a second portion 156b formed by the lock core 126. The locking elements 154 are respectively constructed in two parts in the cam lock 120, and respectively include a steel pin 154a and a magnet 154b, which are held together by the magnetic force between the steel pin 154a and the magnet 154b.

[0092] The locking element 154 can be in a locking position (see Figure 2c and Figure 2e ) and release position (see Figure 2d and Figure 2f ). In the locked position ( Figure 2c and Figure 2e ), the locking element 154 is arranged so that the corresponding steel pin 154a is arranged in the first part 156a and the second part 156b of the corresponding receiving portion 156, and thus prevents the lock cylinder 126 from rotating in the lock housing 122 between the open position and the locked position in a form-fitting manner. Figure 2d and Figure 2f ), the locking element 154 is arranged so that the steel pin 154a is arranged only in the first part 156a of the receiving portion 156, and the magnet 154b is arranged only in the second part 156b of the receiving portion 156, so that the locking element 154 releases the rotation of the lock cylinder 126 in the lock housing 122 between the open position and the locked position in the released position, and Figure 2g As shown, the lock cylinder 126 is rotated with the steel pin 154a and the magnet 154b being separated accordingly.

[0093] When the key 102 having the magnet structure 112 is inserted into the first end 138 of the lock cylinder 126, the locking element 152 is configured to release the rotation of the lock cylinder 126 between the open position and the locked position in the lock housing 122. This is achieved in the cam lock 120 by matching the number, position and magnetic pole direction of the magnets 114 of the magnet structure 112 of the key 102 with the number, position and magnetic pole direction of the magnets 154b of the locking element 154, so that when the key 102 is inserted, the magnets 114 of the magnet structure 112 and the corresponding magnets 154b of the locking element 154 are respectively opposite to each other with the same magnetic poles, so that a magnetic repulsion force acts on the magnets 154b, which moves the magnets 154b and thus the corresponding steel pins 154a in the receptacles 156 to the release position.

[0094] In this way, the cam lock 120 can be unlocked using a key 102 that matches it and has a given magnet structure, while a key of the same type with respect to the key profile 108 but having a different magnet structure will not cause the cam lock 120 to be unlocked. Therefore, the cam lock 120 and the key 102 are magnetically encrypted by the number, position and magnetic pole direction of the magnets 114 of the magnet structure 112, and the number, position and magnetic pole direction of the magnets 154b of the locking element 154 that are matched thereto.

[0095] In order to hold the locking element 154 in the locked position when the key 102 is pulled out, a holding element 162 in the form of a ferromagnetic element, for example a steel element, is provided in the lock cylinder 126. The magnet 154b and thus the locking element 154 as a whole are held in the locked position by the magnetic attraction between the magnet 154b of the locking element 154 and the holding element 162. The strengths of the magnet 114 and the magnet 154b of the locking element 154 are matched so that when the key 102 is inserted, the magnetic attraction between the magnet 154b and the holding element 162 is overcome by the magnetic repulsion between the magnet 114 and the magnet 154b, and the locking element 154 is moved to the release position.

[0096] In the present example, the lock contour 140 and the key contour 108 are constructed asymmetrically so that the key contour 108 can only be inserted into the lock contour 140 in a predetermined direction, which ensures the correct orientation of the magnet structure 112 relative to the magnet 154b of the locking element 154 when the key 102 is inserted.

[0097] The four side surfaces of the lock contour 140 form the abutment surfaces 167 of the abutment surface structure 168 of the cam lock 20 in the cam lock 120, and the abutment surfaces 167 are provided for abutting the magnet structure 112 in the direction given by the asymmetrical shape of the lock contour 140 and the key contour 108. The abutment surfaces 167 are arranged on the lock contour 140 in the cam lock 120. Correspondingly, the locking element 154 is also arranged on the lock contour 140, that is, in the region of the abutment surfaces 167.

[0098] In this way, the security of the cam lock 120 against unauthorized manipulation is increased, since the abutment surface 167 is not easily accessible from the outside and it is therefore difficult to actuate the cam lock 120 by means of the stationary magnet without a matching key.

[0099] Figure 3a-Figure 3l A third embodiment of a lock, key and lock system is shown. Figure 3a-Figure 3b A three-dimensional image viewed from above ( Figure 3a ) and the three-dimensional image viewed from below ( Figure 3b ) shows key 202. Figure 3cThe lock 220 is shown in a three-dimensional illustration, viewed obliquely from above or from the front, wherein some parts are represented as transparent using dashed lines for the sake of clarity. Figure 3d A side view of the key 202 and the lock 220 is shown. Figure 3e A top view of lock 220 is shown. Figure 3f and Figure 3g Shows the corresponding Figure 3e The three-dimensional view of the partially cut-away section indicated by "III f" in FIG. 1 shows, more specifically, the state before the key 202 is inserted ( Figure 3f ) and after key 202 is inserted ( Figure 3g ) view. Figure 3f Further enlarged details are shown in a sectional view along the viewing direction marked with an "X" in the three-dimensional view (in the circle drawn with dot-dash lines). Figure 3h and Figure 3i Shows the corresponding Figure 3e The cross-sectional view of the section marked with "IIIh" in FIG. 1 shows the cross-sectional view of the section marked with "IIIh" in FIG. 1 , which ... Figure 3h ) and after inserting the key 202 ( Figure 3i ) view. Figure 3j , Figure 3k and Figure 3l Shows the corresponding Figure 3d The cross-sectional view of the cross section indicated by "IIIj" in FIG. 1 shows, more specifically, the cross-sectional view before the key 202 is inserted ( Figure 3j ), after inserting key 202 ( Figure 3k ) and after the lock cylinder 226 with the inserted key 202 is rotated 45° ( Figure 3l ) view.

[0100] The key 202 and the lock 220 together form a lock system 280 .

[0101] In this example, the lock 220 is configured as a cam lock, and the lock system 280 is correspondingly configured as a cam lock system. Alternatively, the lock 220 can also be configured as a rod lock or an axial lock, and the lock system 280 can be correspondingly configured as a rod lock system or an axial lock system.

[0102] The key 202 is a plug-in key with a handle 204 and a plug-in sleeve 206, which are integrally constructed in this example. The plug-in sleeve 206 has a key profile 208, which includes four segment-shaped protrusions 209 in this example. However, other key profiles 208 can also be considered. The plug-in sleeve 206 of the key has a magnet structure 212 with a plurality of magnets 214, 215, and the magnets 214, 215 have a given position and a given magnetic pole direction respectively. Some magnets 214 of the magnet structure 212 are arranged in the face 210 of the plug-in sleeve 206, which is retracted relative to the segment-shaped protrusion 209 and is located between the segment-shaped protrusions 209. Another magnet 215 of the magnet structure 212 is arranged in the center face 211 retracted relative to the face 210.

[0103] The magnetic pole directions of the respective magnets 214, 215 are partially indicated in the drawings by "N" (magnetic north pole) and "S" (magnetic south pole).

[0104] The cam lock 220 has a lock housing 222 (for clarity, the Figure 3c The lock housing 222 has an internal passage 224 in which a lock cylinder 226 is supported rotatably about an axis C. The lock housing 222 has a flange 230 on the front face 228 of the cam lock 220, from which a housing body 232 with an external thread 234 extends. The assembly of the cam lock 220 can be carried out as described for the cam lock 20.

[0105] The lock cylinder 226 is configured at a first end 238 accessible from the front 228 for the torque-transmitting insertion of the key 202. For this purpose, the lock cylinder 226 has a lock contour 240 at its first end 238 that matches the key contour 208, which is configured here in the form of four recesses 241 that match the segment-shaped projections 209.

[0106] At a second end 242 of the lock core 226, which is opposite to the first end 238, the lock core 226 carries a rotating tongue 244, which is connected to the lock core 226 in a rotationally fixed manner via mating contours 246, 248 on the lock core 226 and the rotating tongue 244 and is fixed by means of a screw 250. When the key 202 is inserted, the lock core 226 and thus the rotating tongue 244 are rotated between the open position and the closed position in a manner similar to that described above for the cam lock 20.

[0107] The cam lock 220 also has a locking member 252 that prevents the lock cylinder 226 from rotating between the unlocked position and the locked position in the lock housing 222 when the key 202 is removed. Figure 3a-Figure 3lThe example includes an axial locking element 254 for axial locking and a radial locking element 255 for radial locking.

[0108] The axial locking element 254 is constructed in two parts and includes a steel pin 254a and a magnet 254b. The axial locking element 254 is supported axially movably in a receiving portion 256 formed by the lock core 226 and the lock housing 222. The receiving portion 256 accordingly includes a first part 256a formed by the lock housing 222 and a second part 256b formed by the lock core 226.

[0109] The locking element 254 can be in a locking position (see Figure 3h ) and release position (see Figure 3i ). In the locked position ( Figure 3h ), the locking element 254 is arranged so that the corresponding steel pin 254a is arranged in the first part 256a and the second part 256b of the corresponding receiving portion 256, and thus prevents the lock cylinder 226 from rotating between the open position and the locked position in the lock housing 222 in a form-fitting manner. Figure 3i ), the locking element 254 is arranged so that the steel pin 254a is only arranged in the first part 256a of the accommodating portion 256, and the magnet 254b is only arranged in the second part 256b of the accommodating portion 256, so that the locking element 254 releases the rotation of the lock core 226 in the lock housing 222 between the open position and the locked position in the released position, and when the radial locking element 255 is also in the released position, the lock core 226 is rotated under the premise that the steel pin 254a and the magnet 254b are separated accordingly.

[0110] The radial locking element 255 is also constructed in multiple parts and includes a steel pin 255a and a magnet 255b as well as two slides 255c-255d, which are arranged in a receiving portion 257 of the lock core 226. The receiving portion has a central axial portion 257a and a radial portion 257b, in which the steel pin 255a and the magnet 255b are supported axially movably, and the slides 255c-255d are supported radially movably in the radial portion. The slides 255c-255d can be moved in the radial portion 257b of the receiving portion 257 in the corresponding locking position ( Figure 3f ) and release position ( Figure 3g ). In the locked position ( Figure 3f ), the sliders 255c-255d of the locking element 255 engage in corresponding radial recesses 259 in the lock housing 222 and thus prevent the lock cylinder 226 from rotating in the lock housing 222 between the open position and the locked position in a form-fitting manner. Figure 3g), the sliders 255c-255d of the locking element 255 are pulled back into the accommodating portion 257 and do not engage with the recess 259, so that the locking element 255 in this released position releases the rotation of the lock cylinder 226 in the lock housing 222 between the open position and the locked position.

[0111] The locking element 252 is designed to release the lock cylinder 226 for rotation in the lock housing 222 between an open position and a locked position when the key 202 having the magnet structure 212 is inserted onto the first end 238 of the lock cylinder 226 .

[0112] For the axial locking element 254, this is achieved in the cam lock 220 by the following method, namely, matching the number, position and magnetic pole direction of the magnets 214 of the magnetic structure 212 of the key 202 with the number, position and magnetic pole direction of the magnets 254b of the axial locking element 254, so that when the key 202 is inserted, the magnets 214 of the magnetic structure 212 and the corresponding magnets 254b of the axial locking element 254 are respectively opposed to each other with the same magnetic poles, so that a magnetic repulsion force acts on the magnets 254b and then acts on the relevant locking element 254, and the magnetic repulsion force causes the locking element 254 to move out and move to the release position.

[0113] With regard to the radial locking element 255, unlocking in the cam lock 220 is achieved by matching the position and magnetic pole direction of the magnet 215 with the position and magnetic pole direction of the magnet 255b so that when the key 202 is inserted, the magnet 215 and the magnet 255b of the magnetic structure 212 are opposite to each other with the same magnetic poles, so that a magnetic repulsion force acts on the magnet 255b and thus on the steel pin 255a, which moves the steel pin 255a toward the slider 255c-255d. Mutually matched inclined surfaces 264, 265 are provided on the slider 255c-255d and the steel pin 255a, which act together when the steel pin 255a moves toward the slider 255c-255d so that the slider 255c-255d is pulled back into the receiving portion 257 and thus the locking element 255 is moved into the release position.

[0114] In this way, the cam lock 220 can be unlocked using a key 202 that matches it and has a given magnet structure, while a key with the same type of key profile 208 but with a different magnet structure will not cause the cam lock 220 to be unlocked. Therefore, the cam lock 220 and the key 202 are magnetically encrypted by the number, position and magnetic pole direction of the magnets of the magnet structure and the number, position and magnetic pole direction of the locking elements 254 that match it.

[0115] In order to keep the axial locking element 254 in the locked position when the key 202 is pulled out, a retaining element 262 in the form of a ferromagnetic element is provided in the lock core 226. The locking element 254 is held in the locked position by the magnetic attraction between the magnet 254b of the locking element 254 and the retaining element 262. The strengths of the magnet 214 and the magnet 254b of the locking element 254 are matched so that when the key 202 is inserted, the magnetic attraction between the magnet 254b and the retaining element 262 is overcome by the magnetic repulsion between the magnet 214 and the magnet 254b, and the locking element 254 is moved into the release position.

[0116] In order to keep the radial locking element 255 in the locked position when the key 202 is pulled out, a retaining element 263 in the form of a ferromagnetic element is also provided on the central receiving portion 257a in the lock core 226. In addition, magnets 266 that are paired with each other are provided on the sliders 255c-255d, and the magnets 266 are arranged so that every two magnets 266 with the same polarity are opposite. By the magnetic attraction between the magnet 255b and the retaining element 263, the magnet 255b and thus the steel pin 255a are maintained in a position away from the sliders 255c-255d. By the magnetic repulsion between the magnets 266 that are paired with each other on the sliders 255c-255d, the sliders 255c-255d are maintained in the recess 259, and thus the locking element 255 is maintained in the locked position. The strengths of magnet 215, magnet 255b and magnet 266 are matched so that when key 202 is inserted, the magnetic attraction between magnet 255b and retaining element 263 is overcome by the magnetic repulsion between magnet 215 and magnet 255b, and when magnet 255b and steel pin 255a move toward sliders 255c-255d, sliders 255c-255d overcome the magnetic repulsion of magnet 266 through the interaction of inclined surfaces 264, 265 and are pulled back into the accommodating portion 257, thereby moving the radial locking element 255 to the release position.

[0117] In the cam lock 220 , the surface 267 located between the recesses 241 and the surface 268 protruding in the center form corresponding contact surfaces of a contact surface structure 269 of the cam lock 220 , which is provided for contacting the magnet structure 212 .

[0118] By means of the combination of a radially movable locking element and an axially movable locking element, a particularly high level of vibration resistance of the locking device is achieved in the cam lock 220 .

[0119] Figure 4a-4e A fourth embodiment of a lock, key and lock system is shown. Figure 4a The key 302 and the lock 320 are shown in a three-dimensional illustration as viewed obliquely from below or from behind. Figure 4b The key 302 is shown in a view from below. Figure 4c The lock 320 is shown in a top view from the lock profile. Figure 4d-4e Corresponding to Figure 4b-Figure 4c The three-quarter cross-sectional view of the section marked with "Ⅳd / e" in FIG. 3 shows the key 302 and the lock 320, and more specifically, shows the key 302 before it is inserted ( Figure 4d ) and after inserting the key 302 ( Figure 4e ) view.

[0120] Key 302 and lock 320 together form a lock system 380 .

[0121] The lock 320 basically has the same Figure 1a-1g The lock 20 has a similar structure. Figure 1a-1g Corresponding parts are partly provided with the same reference numerals, even if they are Figure 1a-1g and Figure 4a-4e may be constructed differently.

[0122] The lock 320 differs from the lock 20 in that the lock cylinder 326 has, at a first end accessible from the front side 28 of the lock 320 , a contour piece 339 which preferably protrudes laterally relative to the flange 30 of the lock housing 22 and has a lock contour 340 , which is in the present case designed as an outer contour.

[0123] When being installed in the opening in the thin wall, the flange 30 of the lock housing 22 constitutes the abutment surface on one side of the thin wall. A nut can be screwed onto the external thread 34 from the other side of the thin wall so that the lock is fixed in the opening.

[0124] The key 302 has a socket part 306, which has a key contour 308 in the form of an inner contour that matches the lock contour 340. A plurality of magnets 314 with given positions and magnetic pole directions are arranged in the retraction surface 310 surrounded by the key contour 308, and these magnets form a magnet structure 312. In the key 302, the handle part 304 is formed by an operating contour arranged on the back side of the socket part 306.

[0125] In the present lock 320, the lock core 326 is constructed in a multi-piece manner with a contour piece 339 and a core piece 327 arranged in the inner channel 24 of the lock housing 22, wherein the contour piece 339 and the core piece 327 are connected to each other in a rotationally fixed manner. For this purpose, in the present embodiment, the contour piece 339 has an outer contour 370, and the core piece 327 has a matching inner contour 371, for example a polygonal contour, which are engaged with each other in a form-fitting manner. In addition, in the present embodiment, the contour piece 339 is connected to the core piece 327 in such a way that the bolt 50 guided through the core piece 327 is screwed into the inner thread 372 at the contour piece 339. The multi-piece design of the lock core 326 with an independent contour piece 339 allows the contour piece to be selected from a large number of different types of contour pieces as required.

[0126] Alternatively, the contour element 339 and the core element 327 can also be designed in one piece.

[0127] On the flange 30 of the lock housing 22, as Figure 4d As shown, a circumferential seal 323 , such as an O-ring, can be provided, preferably adjacent to the core 327 , which seals the lock housing 22 against the wall and can also prevent moisture from penetrating between the lock housing 22 and the core 327 .

[0128] The locking member 352 of the cam lock 320 includes a plurality of locking elements 354, which are movably supported in receiving portions 356 on the respective edge sides of the lock housing 22. The locking elements 354 can be in a locking position (see Figure 4d ) and release position (see Figure 4e ). In the locked position ( Figure 4d ), the locking element 354 engages in a corresponding recess 358 of the lock core 326 and thereby prevents the lock core 326 from rotating in the lock housing 22 between the open position and the locked position in a form-fitting manner. Figure 4e ), the locking element 354 is pulled back into the receiving portion 356 and does not engage with the recess 358, so that the locking element 354 releases the lock cylinder 326 from rotating between the open position and the locked position in the lock housing.

[0129] The locking element 354 is designed as a magnet, the position and magnetic pole direction of which are matched to the magnet structure 312 of the key 302 so that the locking element 354 moves into the release position ( Figure 4d). For this purpose, the locking elements 354 constructed as magnets and the magnets 314 of the magnetic structure 312 are arranged and oriented in particular in such a way that when the key 302 is inserted, each locking element 354 is opposed to the corresponding magnet 314 of the magnetic structure 312 in an anti-parallel magnetic pole direction, so that a force acts on the locking element 354, which moves the locking element 354 into the release position. In addition, in the present example, in the lock core 326, in the contour part 339 of the lock core 326, a retaining element 362 in the form of a ferromagnetic element is provided, which retains the locking element 354 in the locked position when the key 302 is not attached ( Figure 4c ). The magnets 314 and the locking elements 354 are matched such that the holding force between the holding element 362 and the corresponding locking element 354 is overcome by the repulsive force between the magnets 314 and the corresponding locking element 354 when the key 302 is attached.

[0130] The lock contour 340 and the key contour 308 are designed asymmetrically in this example, so that the key contour 308 can only be attached to the lock contour 308 in a predetermined orientation. With ten locking elements 354 designed as magnets in this example and corresponding ten magnets 314 of the magnet structure 312, two 10 = 1024 different possible combinations for the orientation of the magnet poles.

[0131] The magnetic pole directions of the individual magnets 314 or locking elements 354 are partially indicated in the figures by “N” (magnetic north pole) and “S” (magnetic south pole).

[0132] Furthermore, in this example, the receptacles 356 for the plurality of locking elements 354 and the associated recesses 358 have different distances from the rotation axis D of the lock cylinder 326 (see Figure 4c ). This prevents the locking element 354 from reaching another receptacle 356 and thus reaching a locked position when or after the lock cylinder 326 is pivoted, in particular from the locked position, and thus from reaching a locked position which would prevent the lock cylinder 326 from being pivoted back into the locked position, for example. As a result, the lock cylinder 326 can be freely moved into the locked position, for example, because when the key 302 is pulled out, the locking element 354 can only reach its respective receptacle 356 again towards the locked position when the locked position is reached.

[0133] Furthermore, by means of different distances of the receptacle 356 from the rotation axis D of the lock cylinder 326, for example, the number of possible combinations for the magnet arrangement 312 can also be increased, since in addition to the magnetic pole directions of the individual magnets 314, different radial positions of the individual magnets 314 relative to the rotation axis D of the lock cylinder 326 can also be selected. For this purpose, the magnetic forces of the locking element 354 and the magnet 314 are preferably set in such a way that the locking element 354 is moved into the corresponding release position only when the associated magnet 314 is positioned at a predetermined distance relative to the rotation axis D.

[0134] Figure 5a-5e A fifth embodiment of a lock, key and lock system is shown. Figure 5a Key 402 and lock 420 are shown in three dimensions. Figure 5b The key 402 is shown in a top view from the front of the key outline. Figure 5c The lock 420 is shown in a top view from the lock profile. Figure 5d-5e To correspond to Figure 5b-Figure 5c The three-quarter cross-sectional view of the section marked with "Vd / e" in FIG. 4 shows the key 402 and the lock 420, and more specifically, shows the key 402 before it is inserted ( Figure 5d ) and after inserting the key 402 ( Figure 5e ) view.

[0135] Key 402 and lock 420 together form a lock system 480 .

[0136] The lock 420 basically has the same Figure 1a-1g The internal structure of the lock 20 is similar to that of the lock 20. Figure 1a-1g Corresponding parts are partly provided with the same reference numerals, even if they are Figure 1a-1g and Figure 4a-4e may be constructed differently.

[0137] The difference between the lock 420 and the lock 20 is that the lock 420 is not configured as a cam lock, but is configured as a profiled cylinder having a locking protrusion 444 connected to the lock core 426 in a rotationally fixed manner, such as Figure 4a As shown, when the lock 420 is not operated, the locking projection 444 can optionally be held in a given position by means of a spring 445. The lock housing 422 has the shape of a profiled cylinder, so that the lock 420 can be used instead of a conventional cylindrical lock.

[0138] The lock cylinder 426 has a lock contour 440 at a first end accessible from the front side 28 of the lock 420, which is configured as an inner contour, for example, as a quadrilateral recess. The key 402 accordingly has a socket portion 406, which has a key contour 408 in the form of a protruding outer contour that matches the lock contour 440. Alternatively, the lock contour 440 can also be configured as an outer contour, for example, a quadrilateral protrusion, and the key contour 408 can be configured as an inner contour, for example, a quadrilateral inner contour.

[0139] The locking member 452 of the lock 420 includes a plurality of locking elements 454 configured as magnets, which are movably supported in receiving portions 456 on the corresponding edge sides of the lock housing 422. The locking elements 454 can be in the corresponding receiving portions 456 in the locking position ( Figure 5d ) and release position ( Figure 5e ), in the locked position, the locking element 454 engages in the corresponding recess 458 of the lock core, and when the key 402 with a matching magnet structure 412 is inserted, the locking element 454 moves into the released position and releases the rotation of the lock core 426 in the lock housing 422.

[0140] In the present embodiment, the lock cylinder 426 is constructed in two parts, which has a core piece 427 arranged in the internal channel 424 of the lock housing 422, and a profile piece 439 having a lock profile 440. The core piece 427 and the profile piece 439 are connected to each other in a rotationally fixed manner, in that the outer contour 470 of the core piece engages in a form-fitting manner in the inner contour 471 of the profile piece 439, and the bolt 50 is screwed through the core piece 427 into the inner thread 472 in the profile piece 439.

[0141] The lock contour 440 and the key contour 408 are designed asymmetrically, so that the key 402 can only be attached to the lock contour 440 in a given orientation. By means of the locking element 452, which in this example comprises nine locking elements 454 designed as magnets, and the corresponding nine magnets 414 of the magnet structure 412, a 2-axis rotation is obtained for the magnetic pole direction of the magnets. 9 = 512 different possible combinations.

[0142] The magnetic pole directions of the individual magnets 414 or locking elements 454 are partially indicated by “N” in the figures.

[0143] (magnetic north pole) and "S" (magnetic south pole).

[0144] As in lock 320, in lock 420, the receptacle 456 for the locking element 454 and the associated recess 458 are also at different distances from the axis of rotation of the lock cylinder 426 (see Figure 5c) in order to prevent the locking element 454 from reaching the other receptacle 456 and thus reaching a locking position when the lock cylinder 426 is pivoted, which can prevent the lock cylinder 426 from rotating, for example, back to the initial position.

[0145] In the lock 420 , the retaining element 462 is designed as an annular plate made of ferromagnetic metal, which is inserted into the contour part 439 .
