Description

TECHNICAL FIELD

[0001] The invention relates to a lock, in particular a cam lock, having a lock housing, having a lock cylinder which is rotatably mounted in the lock housing, wherein the lock cylinder is configured on a first end which is accessible from the front of the lock, for torque-transmitting insertion of a key, in particular of a plug-in key, and wherein the lock has a blocking element which, in the event of the key being removed, prevents rotation of the lock cylinder in the lock housing between an open position and a latched position. 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

[0002] Locks, for example cam locks, are known in the prior art as industrial fittings, for example for latching thin-walled panel doors. Simple cam locks have a lock profile on the lock cylinder, for example in the form of a quadrangle or a quadrangular recess, for the insertion of a key having a counter- shaped key profile, for example a plug-in key having a quadrangular hollow profile or a quadrangular profile, so that a high torque can be transmitted from the plug-in key onto the lock cylinder and, in turn, onto a rotary tongue. In this way, the usually rather high frictional forces between the rotary tongue and the blocking surface of the frame (which surrounds the panel door) which is engaged from behind by the rotary tongue can be overcome when the cam lock is opened or latched. The disadvantage of such cam locks is the low security against unauthorized operation, since such cam locks can be opened or latched quite easily, for example with a pair of pliers, even without a matching plug-in key.

[0003] Furthermore, it is known from the prior art that some cam locks have a conventional cylinder lock integrated in them or in their lock cylinder. Such conventional cylinder locks have a lock cylinder with a key channel, wherein a movable blocking element, for example a blocking tab (for a tabular cylinder lock), a blocking disc (for a discoidal cylinder lock) or a blocking pin (for a pin-shaped cylinder lock), prevents rotation of the lock cylinder in the lock housing when the blocking element is not mechanically moved into a specific position by means of the key profile of a matching key inserted into the key channel. High security against unauthorized operation is thereby achieved. However, conventional cylinder locks are more sensitive than plug-in key locks and are therefore not robust in adverse environmental conditions or require a lock cover to prevent dust and dirt from contaminating the delicate key channel or the movable blocking element, thereby complicating operation of the lock. Furthermore, with a common cylinder key, only a small torque can be transmitted due to the small lever action of the cylinder key and due to the delicate mechanical mechanism of conventional cylinder locks, which limits the use in cam locks as described above, which partially require a high torque for opening and latching.

[0004] In order to transmit high torques even with a conventional cylinder lock, it is furthermore known that, in addition to the cylinder lock, a separate rotary handle is provided for unlocking, which serves to open or close a cam lock. However, such a cam lock has the disadvantage of an increased complexity of operation and requires a significantly greater installation space. SUMMARY

[0005] Against this background, it is the task of the present application 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 application, the above-mentioned task is solved by a lock, in particular a cam lock, having a lock housing and a lock cylinder rotatably supported in the lock housing, wherein the lock cylinder is configured on a first end accessible from the front of the lock for torque-transmitting insertion of a key, in particular a plug-in key, and wherein the lock has a blocking element which, in the event of extraction of the key, prevents a rotational movement of the lock cylinder in the lock housing between an open position and a closed position, wherein the blocking element is configured to release the rotational movement of the lock cylinder in the lock housing between the open position and the closed position when a key, in particular a plug-in key, having a given magnet structure is inserted onto the first end of the lock cylinder.

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

[0008] The lock can in particular be a cam lock. In this case, the lock cylinder preferably carries a rotary tongue on the second end. The rotary tongue can in particular be detachably connected to the lock cylinder. With this lock, it is then possible to transmit a preferably high or higher torque onto the rotary tongue in order to lock the rotary tongue, for example, behind a 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 lever lock, for example a door lever lock. In this case, the second end of the lock cylinder is preferably coupled to one or more levers in such a way that the rotational movement of the lock cylinder is converted into a push movement of the one or more levers. For example, the lock cylinder can carry a gear wheel on the second end, which engages with a counterpart, for example a toothed rack, of the lever lock.

[0010] It is further conceivable that the lock is an axial lock. In this case, on the second end of the lock cylinder, for example, a profile can be provided which is movable in the axial direction, which can be moved into a counter- profile on the frame, for example, for locking, and / or moved out of this counter- profile for unlocking. It is further conceivable that the second end of the lock cylinder carries a profile, for example a threaded profile or a bayonet profile, which can be turned into a counter- profile on the frame, for example, for locking, and / or turned out of this counter- profile for unlocking. Combinations of these design variants are also conceivable.

[0011] It is further conceivable that the lock is configured in the shape of a profi lzyl inder. For this purpose, the lock housing can in particular have the shape of a profi lzyl inder. This makes it possible to use the lock instead of a conventional cylinder lock, for example instead of a plate cylinder lock, a disc cylinder lock or a pin cylinder lock. In particular, in this way, the lock can easily be installed in a locking device for profi lzyl inders. Such a profi lzyl inder-shaped lock preferably has a locking protrusion which is connected to the lock cylinder in a torsionally rigid manner.

[0012] Since the locking element is configured for releasing the turning of the lock cylinder in the lock housing between the open position and the locked position when a key sleeve having a predetermined magnet structure is inserted onto the first end of the lock cylinder, a magnetic unlocking function is provided, so that the key profile and the corresponding lock profile of the lock cylinder are preferably able to be optimized, for example more robustly configured, in terms of geometry and mechanics for the transmission of high torques.

[0013] In contrast, in conventional cylinder lock systems, the shape of the cylinder lock-key and the key channel of the cylinder lock in which the key is accommodated is mechanically configured complex in order to realize the mechanical unlocking function, which results in only very small torques being able to be transmitted.

[0014] The lock cylinder is configured on the first end which is accessible from the front of the lock for the torque-transmitting insertion of a key. In this way, the lock cylinder can be operated by an inserted matching key when the locking element releases the turning of the lock cylinder.

[0015] The first end of the lock cylinder is preferably in particular configured such that a matching key can be inserted onto the first end of the lock cylinder in a form-fit manner in such a way that a torque transmission from the key to the lock cylinder about the turning axis of the lock cylinder is possible. In this way, the lock cylinder can be operated by the key. The insertion of the key can also include the insertion of a protruding portion of the key profile, for example a polygonal profile, of the key into a counter- recess on the first end of the lock cylinder.

[0016] The blocking elements are configured such that they prevent a rotation of the lock cylinder in the lock housing between the open position and the locked position in the event of the key being withdrawn. The blocking elements can be configured, for example, to prevent a rotation of the lock cylinder in the lock housing from the open position into the locked position in the event of the key being withdrawn. Additionally or alternatively, the blocking elements can be configured, for example, to prevent a rotation of the lock cylinder in the lock housing from the locked position into the open position in the event of the key being withdrawn. It is conceivable, but not necessary, for the blocking elements to prevent any rotation of the lock cylinder in the lock housing in the event of the key being withdrawn. It is particularly conceivable for designs in which the lock cylinder can also be moved, for example, from an intermediate position between the open position and the locked position into the open position or the locked position in the event of the key being withdrawn, and the blocking elements only block when the open position and / or the locked position is reached.

[0017] The blocking elements are configured to release a rotation of the lock cylinder in the lock housing between the open position and the locked position when a key having a given magnet structure is inserted onto the first end of the lock cylinder. The blocking elements are therefore provided, in particular, for a magnetic interaction with the given magnet structure, which results in the rotation of the lock cylinder being released.

[0018] The lock is magnetically encrypted by the matching of the blocking elements with the given magnet structure of the key. The use of a matching key having the given magnet structure is therefore required for operating the lock, whereas the use of a key having no magnet structure, or a key having a different magnet structure from the given magnet structure, is only possible to a limited extent, for example only in an intermediate position between the open position and the locked position, or is not possible at all. The given magnet structure therefore determines the configuration of the lock. The magnet structure itself is not part of the lock, however. The blocking elements of the lock are specifically matched to the given magnet structure such that the insertion of a matching key having the given magnet structure results in the blocking elements releasing the rotation of the lock cylinder.

[0019] The above task is also solved according to the invention 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 portion and a plug-in portion, which can also be configured integrally. The plug-in portion has a key profile, in particular a polygonal profile, for plugging onto a lock cylinder, in particular a lock cylinder of the above-mentioned lock or an embodiment of the lock, in particular for transmitting torque. Furthermore, the key has a magnet structure on the plug-in portion, which is used, in particular, for a magnetic interaction with a blocking element of the lock, in particular a blocking element of the above-mentioned lock or an embodiment of the lock.

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

[0021] Furthermore, according to the application, the aforementioned task is achieved by a lock system, in particular a cam lock system, having a lock as described above or an embodiment of the lock, and having a key matching the lock, in particular a key as described above 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 in particular matched to each other such that the lock cylinder is configured on the first end for plugging in the key torque-transmitting and the locking element of the cam lock is provided for releasing the rotation of the lock cylinder in the lock housing between the open position and the latching position when the key is plugged onto the first end of the lock cylinder. In particular, the magnet structure of the key is a given magnet structure for which the locking element is configured to release the rotation of the lock cylinder in the lock housing between the open position and the latching position when the key with the given magnet structure is plugged onto the first end of the lock cylinder.

[0023] In the following, different embodiments of the lock, the key and the lock system will be described, wherein each embodiment is respectively applicable to the lock, the key and the lock system independently of each other. Furthermore, each embodiment can be combined arbitrarily with each other.

[0024] In an embodiment, the lock cylinder has on the first end a lock contour, in particular a polygon contour, for plugging in the key, preferably a plug-in key, in particular a polygon key, torque-transmitting. With such a lock contour it is possible to plug in a plug-in key with a mating key contour, preferably transmitting a high torque or a higher torque. Furthermore, such a lock contour for plug-in keys is very robust compared to the key channel of a conventional cylinder lock system, in particular under adverse environmental conditions, for example with dust. The lock contour can in particular have one or more recesses and / or one or more protrusions.

[0025] The lock contour of the lock cylinder is provided for plugging in the plug-in key torque-transmitting. Accordingly, the lock contour is in particular configured such that, when the assigned key is plugged in, the lock contour forms a form fit with the key contour of the key for transmitting torque.

[0026] The lock contour can for example have recesses, for example polygonal recesses, for accommodating counter- protrusions, for example polygonal protrusions, of the key contour of the assigned key. Furthermore, the lock contour can for example have protrusions, for example polygonal protrusions, for being accommodated in counter- recesses, for example polygonal recesses, of the key contour of the assigned key.

[0027] The lock cylinder can also have a profile piece with a lock contour, in particular an outer contour, wherein the profile piece can project laterally on the first end relative to the lock housing. The key can accordingly have a key contour, in particular an inner contour, which matches the lock contour.

[0028] Preferably, the profile piece is configured flat and is delimited by the edge-side outer contour which constitutes the lock contour. This allows the lock contour to have a very flat configuration. In this way, for example, the user can be prevented from being hooked on the protruding parts of the lock contour. Furthermore, in this way, there are fewer action points for manipulation.

[0029] Correspondingly, the key can preferably have an inner contour which delimits a region configured flat in which, for example, a magnet structure, or one or more magnets of a magnet structure, can be arranged. In this way, a robust key with a flat structure can be provided.

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

[0031] The lock contour and / or the key contour are preferably configured asymmetrically such that the key sleeve with the corresponding key contour is only allowed in one direction.

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

[0033] By giving the magnet structure a certain number of magnets, which have a respective given position and optionally a given pole direction, the security of the lock against unauthorized operation can be improved. In particular in this way, different magnet structures can be realized in geometrically identical keys, so that the keys can be magnetically encrypted for the assigned lock, so that with the relevant key the assigned lock can be unlocked, but not a lock that requires a key that is magnetically encrypted in a different way.

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

[0035] Preferably, the blocking member comprises a plurality of blocking elements which are movably supported between a respective blocking position, in which the blocking element prevents the rotation of the cylinder in the lock housing between the open position and the closed position, and a respective release position, in which the blocking element releases the rotation of the cylinder in the lock housing between the open position and the closed position.

[0036] The one or more blocking elements can be movably supported in axial and / or radial direction relative to the rotation axis of the cylinder, for example.

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

[0038] In one embodiment, the cylinder has a receptacle in which the blocking element is movably supported. In the case of a plurality of blocking elements, the cylinder preferably has a plurality of receptacles in which the blocking elements are respectively movably supported. In this way, a particularly compact construction of the lock can be achieved. The receptacle can be constituted by a blind hole or a through-hole on the cylinder, for example, or by an edge-side receptacle which is at least partially constituted by the cylinder.

[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 each of which a locking element is movably supported. In this way, a particularly robust design of the lock can be achieved.

[0040] Furthermore, 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 matching recesses are preferably provided in the lock cylinder, into which recesses the locking element sinks in the locked position and thereby prevents a rotational movement between the lock cylinder and the lock housing. If one or more receptacles are arranged in the lock cylinder, one or more matching recesses are preferably provided in the lock housing, into which recesses the locking element sinks in the locked position and thereby prevents a rotational movement between the lock cylinder and the lock housing.

[0042] In one embodiment, the locking piece comprises a plurality of locking elements which are supported in respective receptacles arranged around the rotational axis of the lock cylinder in the lock housing and / or in the lock cylinder and which engage in the locked position into respectively matching recesses in the lock cylinder and / or in the lock housing. Preferably, at least two, preferably all, of the receptacles and / or matching recesses arranged around the rotational axis of the lock cylinder have different distances from the rotational axis of the lock cylinder. In this way, it can be prevented that a locking element arranged in a receptacle sinks in the rotational movement of the lock cylinder into a recess different from the recess corresponding to the receptacle and prevents a rotational movement between the lock cylinder and the lock housing.

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

[0044] In one embodiment, the lock has a holding element which is configured, in the event of the key being pulled out, to hold the locking element in the locking position by a magnetic interaction, in particular between the holding element and the locking element. In this way, the anti-vibration safety of the lock is improved, so that the locking element is reliably held in the locking position in the event of the key being pulled out, even in the presence of mechanical shocks or vibrations, and thus prevents the lock from being opened or closed in the event of the key being pulled out. In the case of a plurality of locking elements, the holding element can preferably be configured, in the event of the key being pulled out, to hold the plurality of locking elements in the locking position by a magnetic interaction between the holding element and the locking elements.

[0045] The magnetic interaction between the holding element and the 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 the one or more locking elements is a magnetic repulsion interaction.

[0046] For example, the locking element can be or comprise a magnet, and the holding element can likewise be a magnet or consist of a ferromagnetic material, for example the holding element is configured as a ferromagnetic metal plate, for example a steel plate, or as a ferromagnetic pin, for example a steel pin.

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

[0048] Preferably, the magnet structure has a magnet assigned to each locking element, in particular preferably a respective magnet assigned to each locking element.

[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, preferably a plurality, of the locking elements is a magnet or comprises a magnet. In this way, the locking element can be held in the locking position in the event of the key being pulled out, for example by a magnetic attraction interaction with the holding element provided. Furthermore, in this way, when the key sleeve is inserted onto the first end of the lock cylinder, the locking element can move into the release position, for example by a magnetic repulsion interaction with the magnets of the magnet structure of the key.

[0050] The blocking element can in particular have a magnet and a sleeve, in particular a metal sleeve, which surrounds the magnet. In this way, greater shear resistance of the blocking element is achieved in the case of a blocked rotation of the lock cylinder in the lock housing, thereby increasing the durability of the lock.

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

[0052] In one embodiment, the lock comprises an abutment surface structure for the abutment of a given magnet structure, and the blocking element is arranged and configured such that, when the given magnet structure abuts, in particular in a given orientation, on the abutment surface structure, the blocking 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 more convenient, since the user can check the correct position of the key on the lock on the basis of the abutment on the abutment surface structure. Furthermore, by abutting the magnet structure on the abutment surface structure, the spacing between the magnet structure and the blocking element can be kept as small as possible in order to enhance the magnetic interaction between the magnet structure and the blocking element.

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

[0054] If the blocking element comprises one or more blocking elements, these are preferably arranged in the region of the one or more abutment surfaces of the abutment surface structure, such that, upon abutment of the magnet structure, a magnetic interaction between the magnet structure and the blocking element is generated, by which the blocking element is moved into the release position.

[0055] In one embodiment, the abutment surface structure is arranged completely or at least partially separately from the lock contour, for example the abutment surface structure is arranged offset radially outwards or inwards with respect to the rotation axis of the lock cylinder relative to the lock contour. In the 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 enabling a more robust construction of the lock and the key.

[0056] In one embodiment, the abutment surface structure is arranged at least partially on the lock contour, preferably on the inner surface of the accommodation of the lock contour. In a corresponding embodiment of the key, the magnet structure is arranged at least partially on the key contour. In this way, the lock can be better protected from manipulation by magnets located outside.

[0057] In one embodiment, the lock cylinder is constructed in multiple parts and has a cylinder part arranged in an internal channel of the lock housing and a contour part having a lock contour, wherein the cylinder part and the contour part are connected to one another in a torsionally rigid manner. To this end, the cylinder part and the contour part can have mutually mating contours, for example, with which they are positively engaged with one another. The cylinder part and the contour part can be held together, for example, by means of a pin or a bolt, for example by means of a bolt which extends through the cylinder part and is screwed into an inner contour of the contour part.

[0058] By the multiple-part construction of the lock cylinder, in particular of the lock cylinder having a cylinder part and a contour part, it is possible, for example, to provide the lock with the desired lock contour as required by selecting a suitable contour part from a plurality of different types of contour parts.

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

[0060] The key is preferably at least partially made of metal, whereby a high torque can be transmitted. The handle portion of the key extends transversely to the axis of rotation of the key, which is provided for the operation of the key, preferably by at least 2 cm, further preferably by at least 3 cm, particularly preferably by at least 4 cm. In this way, the user can more easily transmit a higher torque to the key and, in turn, to the lock cylinder when the key is inserted into the lock cylinder of the lock.

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

Figures le-if The magnets 14, which are visible in the image and are marked with "N" and "S", have magnetic poles oriented in opposite parallel directions.

[0072] The cam lock 20 has a lock housing 22 with an inner channel 24 in which a lock cylinder 26 is rotatably supported 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 outer thread 34 extends.

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

[0074] The lock cylinder 26 is configured on a first end 38 accessible from the front face 28 for torque-transmitting insertion of the key 2. To this end, the lock cylinder 26 has on its first end 38 a lock profile 40 which is paired with the key profile 8, which is configured here as a polygonal profile, namely a quadrangular recess, for accommodating the key profile 8 configured as a quadrangular protrusion.

[0075] On a second end 42 of the lock cylinder 26 opposite the first end 38, the lock cylinder 26 carries a rotary tongue 44 which is connected to the lock cylinder 26 against rotation by paired profiles 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 turned between an open position and a latching position. Figure lg The latching position in the installed state is shown, in which the rotary tongue 44 engages from behind a latching face 94 of a frame 96 (which surrounds the panel door 92) and in this way locks the panel door 92. On a turn of the lock cylinder 26, for example, by 90°, the lock cylinder 26 or the rotary tongue 44 reaches the open position, in which the rotary tongue 44 no longer engages from behind the latching face 94 so that the panel door 92 can be opened.

[0076] The cam lock 20 also has a blocking element 52 which, in the event of the key 2 being pulled out, prevents the lock cylinder 26 from being turned in the lock housing 22 between the open position and the latching position. In the example shown, Figures la-lg The blocking element 52 comprises a plurality of blocking elements 54 which are movably supported in a receptacle 56 on each edge side of the lock cylinder 26. The blocking elements 54 are movable in the respective receptacle 56 between a blocking position (see Figure le ) and a release position (see Figure If ). In the blocking position ( Figure le) the locking element 54 engages into a corresponding recess 58 of a shape element 60 fixed on the lock housing 22 and thereby form-fittingly prevents the rotation of the lock cylinder 26 in the lock housing 22 between the open position and the closed position. In a release position ( Figure If ) the locking element 54 is pulled back into the accommodation 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 release position.

[0077] The locking element 52 is configured to release the rotation of the lock cylinder 26 in the lock housing 22 between the open position and the closed position when the key 2 with 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 that the locking element 54 is configured as a magnet and the number, position and pole direction of the magnets 14 of the magnet structure 12 of the key 2 are paired with the number, position and pole direction of the locking element 54 in such a way that upon insertion of the key 2 the magnets 14 of the magnet structure 12 and the corresponding locking element 54 with the same pole direction are 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 release position.

[0078] In this way, the cam lock 20 can be unlocked with a key 2 that matches it and has a given magnet structure, while a key of the same key profile 8 type with a different magnet structure does not result in the cam lock 20 being unlocked. Thus, the cam lock 20 and the key 2 are magnetically encrypted by the number, position and pole direction of the magnets 14 of the magnet structure 12 and the number, position and pole direction of the locking element 54 paired therewith.

[0079] In order to keep the locking element 54 in the locking position in the case of the key 2 being pulled out, a retaining 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 profile 40. The locking element 54 is held in the recess 58 by the magnetic attraction force between the locking element 54 and the retaining element 62. The strength of the magnets 14 and the locking element 54 configured as a magnet is matched in such a way that upon insertion of the key 2 the magnetic attraction force between the locking element 54 and the retaining element 62 is overcome by the magnetic repulsion force between the magnets 14 and the locking element 54 and the locking element 54 is moved into the release position.

[0080] In order to improve the durability of the cam lock 20, it is also possible in a possible design variant to use magnets that are each surrounded by a steel sleeve as locking elements 54.

[0081] On the annular end side 64 of the lock housing 22, which in the present example is constituted by one side of the holding element 62, a marking 66 is provided, which is paired with the marking 16 on the key 2 in order to indicate to the user the correct orientation of the key 2 relative to the tumbler lock 20 and thus of the magnet structure 12 relative to the locking element 54.

[0082] The end side 64 simultaneously constitutes a bearing face 67 of a bearing face structure 68 of the tumbler lock 20, which is provided for the bearing of the magnet structure 12 in the direction given by the markings 16 and 66. The bearing face 67 is arranged separately from the lock contour 40, precisely speaking radially outside the lock contour 40 with respect to the axis of rotation A. Correspondingly, the locking element 54 is likewise arranged separately from the lock contour 40, namely in the region of the bearing face 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 bearing on the bearing face 67 is spatially separated from the torque transmission function caused by the form-fit interaction of the key contour 8 and the lock contour 40. Thereby, the lock contour 40 and the key contour 8 can be optimized for torque transmission, in particular more robustly configured, without the movable or delicate components, such as the magnet and the locking element, having to be integrated directly into the lock contour 40 and the key contour 8.

[0084] Figures 2a-2g A second embodiment of a lock, a key and a lock system is shown. Figure 2a The key 102 and the lock 120 are shown in a three-dimensional view. Figure 2b The key 102 and the lock 120 are shown in a three-dimensional view corresponding to Figure 2e The key 102 and the lock 120 are shown in a three-dimensional view, partially sectioned along a section plane denoted "lie" in Figure 2c The key 102 and the lock 120 are shown in a three-dimensional view corresponding to Figure 2d The key 102 and the lock 120 are shown in a three-dimensional view corresponding to Figure 2e The key 102 and the lock 120 are shown in a sectional view along a section plane denoted "lie" in Figure 2c ) before the key 102 is inserted and Figure 2d ) after the key 102 is inserted. Figure 2e A sectional view corresponding to the section plane denoted "lie" in Figure 2c is shown. Figure 2f A sectional view corresponding to the section plane denoted "lie" in Figure 2d is shown. Figure 2g A sectional view corresponding to Figure 2f after the cylinder has been rotated by 45° is shown.

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

[0086] In the present example, the lock 120 is configured as a cam lock, and the lock system 180 is correspondingly configured as a cam lock system. Instead thereof, the lock 120 may, for example, also be configured as a lever lock or an axial lock, and the lock system 180 can be correspondingly configured as a lever lock system or an axial lock system.

[0087] The key 102 is likewise a plug key having a handle portion 104 and a plug portion 106, which in the present example are integrally configured. The plug portion 106 has a key profile 108, which in the present example is configured as a polygonal profile, namely a cross-shaped protrusion. However, other key profiles 108 are also conceivable. In the key 102, a magnet structure 112 having 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 given pole directions, which are partly marked in the figures with "N" (magnetic north pole) and "S" (magnetic south pole).

[0088] The cam lock 120 has a lock housing 122 with an inner passage 124 in which a lock cylinder 126 is rotatably supported 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 outer thread 134 extends. The assembly of the cam lock 120 can take place as described for the cam lock 20.

[0089] The lock cylinder 126 is configured for torque-transmitting insertion of the key 102 on a first end portion 138 which is accessible from the front face 128. To this end, the lock cylinder 126 has on its first end portion 138 a lock profile 140 which is paired with the key profile 108, which in this case is configured as a cross-shaped recess for accommodating the key profile 108 which is configured as a cross-shaped protrusion.

[0090] On a second end portion 142 of the lock cylinder 126 opposite the first end portion 138, the lock cylinder 126 carries a rotation tongue 144 which is connected to the lock cylinder 126 against rotation by paired profiles 146, 148 on the lock cylinder 126 and the rotation tongue 144 and is fixed by means of a screw 150. Upon insertion of the key 102, the rotation of the lock cylinder 126 and thus of the rotation tongue 144 between the open position and the locked position takes place analogously to that described above for the cam lock 20.

[0091] The cam lock 120 also has a blocking element 152 which, in the event of extraction of the key 102, prevents the rotation of the lock cylinder 126 in the lock housing 122 between the open position and the locked position. In the present example, the blocking element 152 is configured as a blocking pin 154 which is arranged in a radial bore 156 of the lock housing 122 and which is configured to be received in a radial recess 158 of the lock cylinder 126. Figures 2a-2gIn the example of the cam lock 120, the locking element 152 comprises a plurality of locking elements 154 which are supported in a receiving portion 156 constituted by the lock housing 122 and the lock cylinder 126 in a radially movable manner relative to the axis of rotation B. The receiving portion 156 accordingly comprises a first portion 156a constituted by the lock housing 122 and a second portion 156b constituted by the lock cylinder 126. The locking elements 154 are respectively two-part in the cam lock 120 and respectively comprise a steel pin 154a and a magnet 154b which are held together by a magnetic force between the steel pin 154a and the magnet 154b.

[0092] The locking elements 154 can be moved in the respective receiving portion 156 between a locking position (see Figure 2c and Figure 2e ) and a release position (see Figure 2d and Figure 2f ). In the locking position Figure 2c and Figure 2e ), the locking elements 154 are arranged such that the respective steel pin 154a is arranged in the first portion 156a and the second portion 156b of the respective receiving portion 156 and thus blocks the rotation of the lock cylinder 126 in the lock housing 122 between the open position and the closed position in a form-fitting manner. In the release position Figure 2d and Figure 2f ), the locking elements 154 are arranged such that the steel pin 154a is arranged only in the first portion 156a of the receiving portion 156 and the magnet 154b is arranged only in the second portion 156b of the receiving portion 156, such that the locking elements 154 release the rotation of the lock cylinder 126 in the lock housing 122 between the open position and the closed position in this release position and, as will be described below, rotate the lock cylinder 126 with the steel pin 154a and the magnet 154b respectively separated. Figure 2g

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

[0094] ​In this way, the cam lock 120 can be unlocked with a key 102 that matches it with a given magnet structure, while a key of the same type of key profile 108 with a different magnet structure does not cause the cam lock 120 to be unlocked. Thus, the cam lock 120 and the key 102 are magnetically encrypted by the number, position and pole direction of the magnets 114 of the magnet structure 112, and by the number, position and pole direction of the magnets 154b of the locking element 154, which are paired therewith.

[0095] In order to keep the locking element 154 in the locking position in the case of the key 102 being pulled out, a retaining element 162 in the form of a ferromagnetic element, for example a steel element, is provided in the lock cylinder 126. By means of the magnetic attraction between the magnets 154b of the locking element 154 and the retaining element 162, the magnets 154b and thus the locking element 154 are held entirely in the locking position. The strength of the magnets 114 and the magnets 154b of the locking element 154 is matched in such a way that, when the key 102 is inserted, the magnetic attraction between the magnets 154b and the retaining element 162 is overcome by the magnetic repulsion between the magnets 114 and the magnets 154b and the locking element 154 is moved into the release position.

[0096] The lock profile 140 and the key profile 108 are configured asymmetrically in the present example, so that the key profile 108 can only be inserted into the lock profile 140 in a predetermined direction, in which direction it is ensured that the magnet structure 112 is in the correct orientation with respect to the magnets 154b of the locking element 154 when the key 102 is inserted.

[0097] The four side faces of the lock profile 140 constitute, in the cam lock 120, the abutment faces 167 of the abutment face structure 168 of the cam lock 20, which are provided for abutment of the magnet structure 112 in the direction given by the asymmetric shape of the lock profile 140 and the key profile 108. The abutment faces 167 are arranged in the cam lock 120 on the lock profile 140. Correspondingly, the locking element 154 is likewise arranged on the lock profile 140, i.e. in the region of the abutment faces 167.

[0098] In this way, the security of the cam lock 120 against unauthorized operation is increased, since the abutment faces 167 cannot easily be accessed from the outside and it is therefore difficult to manipulate the cam lock 120 by means of a stationary magnet without a matching key.

[0099] Figures 3a-3l A third embodiment of a lock, a key and a lock system is shown. Figures 3a-3b A three-dimensional view from an oblique top view Figure 3a ) and a three-dimensional view from an oblique bottom view Figure 3b ) show the key 202. Figure 3cThe lock 220 is shown in a three-dimensional view from an oblique top or oblique front view, wherein some parts are indicated as transparent with 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 the lock 220 is shown.

Figure 3h and Figure 3i A sectional view is shown, which corresponds to the section plane marked with "IIIh" in Fig. 2, showing, in particular, a view before the insertion of the key 202 Figure 3e ) and after the insertion of the key 202 Figure 3h ).

Figure 3l

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

[0101] In the present 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 may, for example, also be configured as a lever lock or an axial lock, and the lock system 280 can be correspondingly configured as a lever lock system or an axial lock system.

[0102] ​​The key 202 is a plug key having a handle portion 204 and a plug portion 206, which in the present example are integrally configured. The plug portion 206 has a key profile 208, which in the present example comprises four ring segment-like protrusions 209. However, other key profiles 208 are also conceivable. The plug portion 206 of the key has a magnet structure 212 with a plurality of magnets 214, 215, which have a given position and a given pole direction, respectively. Some magnets 214 of the magnet structure 212 are arranged in a face 210 of the plug portion 206, which is recessed with respect to the ring segment-like protrusions 209, between the ring segment-like protrusions 209. Another magnet 215 of the magnet structure 212 is arranged in a central face 211, which is recessed with respect to the face 210.

[0103] The pole directions of the individual magnets 214, 215 are indicated in the figures partly in "N" (magnetic north pole) and "S" (magnetic south pole).

[0104] The cam lock 220 has a lock housing 222 (partly indicated as transparent in dashed lines in Figure 3c order to clarify), which has an inner passage 224 in which a lock cylinder 226 is rotatably supported about an axis C. The lock housing 222 has a flange 230 at a front face 228 of the cam lock 220, from which a housing body 232 with an outer 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 for torque-transmitting insertion of the key 202 on a first end portion 238, which is accessible from the front face 228. To this end, the lock cylinder 226 has on its first end portion 238 a lock profile 240, which is paired with the key profile 208, which here is configured in the form of four recesses 241, which are paired with the ring segment-like protrusions 209.

[0106] At a second end portion 242 of the lock cylinder 226, which is opposite the first end portion 238, the lock cylinder 226 carries a rotation tongue 244, which is torsionally connected with the lock cylinder 226 by means of paired profiles 246, 248 on the lock cylinder 226 and the rotation tongue 244, and is fixed by means of a bolt 250. Upon insertion of the key 202, the rotation of the lock cylinder 226 and in turn of the rotation tongue 244 between the open position and the locked position takes place analogously to what has been described above for the cam lock 20.

[0107] The cam lock 220 further has a blocking member 252, which, in the case that the key 202 is pulled out, prevents the rotation of the lock cylinder 226 in the lock housing 222 between the open position and the locked position. The blocking member 252 is arranged in the housing body 232 of the lock housing 222 in the region of the flange 230, and is configured to be moved between a blocking position and a release position by means of a rotation of the key 202. Figures 3a-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 axially movably supported in a receiving portion 256 formed by a lock cylinder 226 and a lock housing 222. The receiving portion 256 correspondingly includes a first part 256a formed by the lock housing 222 and a second part 256b formed by the lock cylinder 226.

[0109] The locking element 254 can be in the locked position in the corresponding receiving portion 256 (see...) Figure 3h ) and release location (see Figure 3i Move between ( ). In the locked position ( Figure 3h In the lock housing 222, the locking element 254 is arranged such that the corresponding steel pin 254a is arranged in the first part 256a and the second part 256b of the corresponding receiving portion 256, thereby preventing the lock cylinder 226 from rotating between the open and locked positions within the lock housing 222. In the released position (… Figure 3i In this configuration, the locking element 254 is arranged such that the steel pin 254a is arranged only in the first part 256a of the receiving portion 256, and the magnet 254b is arranged only in the second part 256b of the receiving portion 256. This releases the rotation of the lock cylinder 226 in the lock housing 222 between the open and closed positions, and when the radial locking element 255 is also in the release position, the lock cylinder 226 rotates with the steel pin 254a and the magnet 254b respectively separated.

[0110] The radial locking element 255 is also constructed in multiple parts and includes a steel pin 255a, a magnet 255b, and two sliders 255c-255d, which are arranged in the receiving portion 257 of the lock cylinder 226. The receiving portion has an intermediate axial portion 257a and a radial portion 257b. The steel pin 255a and magnet 255b are axially movable and supported in the axial portion, while the sliders 255c-255d are radially movable and supported in the radial portion. The sliders 255c-255d are able to be in the corresponding locking position of the radial locking element 255 within the radial portion 257b of the receiving portion 257. Figure 3f ) and release position ( Figure 3g Move between ( ). In the locked position ( Figure 3f In the lock housing 222, the sliders 255c-255d of the locking element 255 engage in corresponding radial recesses 259 within the lock housing 222, thus preventing the lock cylinder 226 from rotating within the lock housing 222 between the open and locked positions in a form-fit manner. In the released position ( Figure 3g) the sliders 255c-255d of the locking element 255 are pulled back into the receptacle 257 and do not engage with the recess 259, so that the locking element 255 releases the rotation of the lock cylinder 226 in the lock housing 222 between the open position and the locked position in this release position.

[0111] The locking element 252 is configured to release the rotation of the lock cylinder 226 in the lock housing 222 between the open position and the locked position when the key 202 with 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 matching the number, position and pole direction of the magnets 214 of the magnet structure 212 of the key 202 to the number, position and 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 magnet structure 212 and the corresponding magnets 254b of the axial locking element 254, respectively, face each other with the same magnetic poles, so that a magnetic repulsion acts on the magnets 254b and, in turn, on the associated locking element 254, which magnetic repulsion moves the locking element 254 out of and into the release position.

[0113] With regard to the radial locking element 255, the unlocking in the cam lock 220 is achieved by matching the position and pole direction of the magnets 215 and the position and pole direction of the magnets 255b to each other in such a way that when the key 202 is inserted, the magnets 215 of the magnet structure 212 and the magnets 255b face each other with the same magnetic poles, so that a magnetic repulsion acts on the magnets 255b and, in turn, on the steel pin 255a, which magnetic repulsion moves the steel pin 255a towards the sliders 255c-255d. On the sliders 255c-255d and the steel pin 255a, mutually matching inclined surfaces 264, 265 are provided, which together act when the steel pin 255a moves towards the sliders 255c-255d in such a way that the sliders 255c-255d are pulled back into the receptacle 257 and, in turn, the locking element 255 is moved into the release position.

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

[0115] In order to keep the axial locking element 254 in the locked position in the case of the key 202 being pulled out, a holding element 262 in the form of a ferromagnetic element is provided in the lock cylinder 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 holding element 262. The strength of the magnet 214 and the magnet 254b of the locking element 254 is matched in such a way that the magnetic attraction between the magnet 254b and the holding element 262 is overcome by the magnetic repulsion between the magnet 214 and the magnet 254b when the key 202 is inserted and the locking element 254 is moved into the released position.

[0116] In order to keep the radial locking element 255 in the locked position in the case of the key 202 being pulled out, a holding element 263 in the form of a ferromagnetic element is also provided in the lock cylinder 226 on the intermediate accommodation 257a. Furthermore, magnets 266 are provided on the sliders 255c-255d which are paired with one another and are arranged in such a way that every two magnets 266 of the same polarity are opposite one another. The magnets 255b and thus the steel pin 255a are held in a position away from the sliders 255c-255d by the magnetic attraction between the magnets 255b and the holding element 263. The sliders 255c-255d and thus the locking element 255 are held in the locked position by the magnetic repulsion between the paired magnets 266 of the sliders 255c-255d in the recesses 259. The strength of the magnet 215, the magnets 255b and the magnets 266 is matched in such a way that the magnetic attraction between the magnets 255b and the holding element 263 is overcome by the magnetic repulsion between the magnet 215 and the magnets 255b when the key 202 is inserted and the sliders 255c-255d are pulled back into the accommodation 257 by the interaction of the inclined faces 264, 265 overcoming the magnetic repulsion of the magnets 266 when the magnets 255b and the steel pin 255a move towards the sliders 255c-255d and thus move the radial locking element 255 into the released position.

[0117] In the cam lock 220, the faces 267 between the recesses 241 and the centrally projecting face 268 form the respective abutment face of an abutment face structure 269 of the cam lock 220 which is provided for abutment of the magnet structure 212.

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

[0119] Figures 4a-4e A fourth embodiment of a lock, a key and a lock system is shown. Figure 4a The key 302 and the lock 320 are shown in a three-dimensional view from an oblique lower or rear perspective.Figure 4b The key 302 is shown in a view taken from below. Figure 4c Lock 320 is shown in a top view taken from the outline of the lock. Figures 4d-4e To correspond to Figures 4b-4c The three-quarter section view marked "Ⅳd / e" shows the key 302 and the lock 320, specifically, the view before the key 302 is inserted. Figure 4d ) and after inserting key 302 ( Figure 4e (view of ).

[0120] Key 302 and lock 320 together constitute locking system 380.

[0121] Lock 320 basically has the same as according to Figures la-lg The structure is similar to lock 20. Referring to the above, regarding... Figures la-lg The description is as follows. Corresponding parts are partially provided with the same reference numerals, even if they are in the same position. Figures la-lg and Figures 4a-4e The structures may differ.

[0122] The difference between lock 320 and lock 20 is that lock cylinder 326 has a profile 339 with a lock profile 340 that protrudes laterally from a flange 30 relative to lock housing 22 at a first end accessible from the front 28 of lock 320. This lock profile is currently constructed as an outer profile.

[0123] When installed into an opening in a thin-walled structure, the flange 30 of the lock housing 22 forms a mating surface on one side of the thin-walled structure. A nut can be screwed onto the external thread 34 from the other side of the thin-walled structure to secure the lock in the opening.

[0124] The key 302 has a socket portion 306, which has a key profile 308 in the form of an inner profile that matches the lock profile 340. A plurality of magnets 314, each with a given position and magnetic pole orientation, are arranged in a retractable surface 310 surrounded by the key profile 308, forming a magnet structure 312. In the key 302, a handle portion 304 is formed by an operating profile arranged on the back side of the socket portion 306.

[0125] In the current lock 320, the lock cylinder 326 is constructed in multiple parts as having a profile piece 339 and a core piece 327 arranged in the interior channel 24 of the lock housing 22, wherein the profile piece 339 and the core piece 327 are connected to one another in a torsion-proof manner. For this purpose, in the present embodiment, the profile piece 339 has an outer contour 370 and the core piece 327 has a mating inner contour 371, for example a polygonal contour, which inner and outer contours engage with one another in a form-fit manner. Furthermore, in the present embodiment, the profile 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 an inner thread 372 at the profile piece 339. The multiple-part design of the lock cylinder 326 with the separate profile piece 339 allows the profile piece to be selected from a large number of different types of profile pieces as required.

[0126] Alternatively, the profile piece 339 and the core piece 327 can also be constructed integrally.

[0127] On the flange 30 of the lock housing 22, as is shown in Figure 4d , a circumferential sealing element 323, for example an O-ring, which is preferably adjoined to the core piece 327, can be provided, which seals the lock housing 22 against the wall and, in addition, can prevent moisture from penetrating between the lock housing 22 and the core piece 327.

[0128] The locking piece 352 of the cam lock 320 comprises a plurality of locking elements 354, which are movably supported in a receiving portion 356 on each edge side of the lock housing 22. The locking elements 354 are movable in the respective receiving portion 356 between a locking position (see Figure 4d ) and a release position (see Figure 4e ). In the locking position Figure 4d , the locking elements 354 engage into a respective recess 358 of the lock cylinder 326 and, as a result, the locking elements prevent the rotation of the lock cylinder 326 in the lock housing 22 between the open position and the closed position in a form-fit manner. In the release position Figure 4e , the locking elements 354 are pulled back into the receiving portion 356 and do not engage with the recess 358, so that the locking elements 354 release the rotation of the lock cylinder 326 in the lock housing between the open position and the closed position.

[0129] The locking elements 354 are constructed as magnets, the position and the pole direction of which are matched to the magnet structure 312 of the key 302 in such a way that the locking elements 354 are moved into the release position when the key 302 is attached Figure 4d). For this purpose, the locking elements 354, which are configured as magnets, and the magnets 314 of the magnet structure 312 are arranged and oriented in particular such that, upon insertion of the key 302, each locking element 354 opposes a respective magnet 314 of the magnet structure 312 with antiparallel pole directions, such that a force acts on the locking element 354, which moves the locking element 354 into the release position. Furthermore, in the present example, in the lock cylinder 326, in the profile piece 339 of the lock cylinder 326, holding elements 362 in the form of ferromagnetic elements are provided, which hold the locking elements 354 in the blocking 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 elements 362 and the respective locking elements 354 is overcome by the repulsive force between the magnets 314 and the respective locking elements 354 upon attachment of the key 302.

[0130] The lock profile 340 and the key profile 308 are configured asymmetrically in the present example, such that the key profile 308 can only be attached to the lock profile 308 in a predetermined orientation. With the ten locking elements 354 configured as magnets, and the respective ten magnets 314 of the magnet structure 312 in the present example, 2 10 = 1024 different combination possibilities for the pole directions of the magnets are obtained in this way.

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

[0132] Furthermore, in the present example, the receptacles 356 for the plurality of locking elements 354 and the associated recesses 358 have different spacings from the rotational axis D of the lock cylinder 326 (cf. Figure 4c ). In this way, it is prevented that, upon or after pivoting of the lock cylinder 326, in particular from the blocking position, the locking elements 354 can reach another receptacle 356 and thus reach the blocking position, which can prevent the rotation of the lock cylinder 326, for example, back into the blocking position. Thereby, the lock cylinder 326 can be freely movable, for example, into the blocking position, since, when the key 302 is pulled out, only upon reaching the blocking position, the locking elements 354 can again reach their respective receptacles 356 towards the blocking position.

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

[0134] Figures 5a-5e A fifth embodiment of a lock, key and lock system is shown. Figure 5a The 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 profile. Figure 5c The lock 420 is shown in a top view from the lock profile. Figures 5d-5e The key 402 and lock 420 are shown in a three-quarter view of the section indicated as "Vd / e" in Figures 5b-5c , precisely the view before the key 402 is inserted Figure 5d and after the key 402 is inserted Figure 5e .

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

[0136] The lock 420 essentially has an internal structure similar to the lock 20 according to Figures la-lg . Reference is made in this regard to the above description for the lock 20 according to Figures la-lg . Corresponding parts are partially provided with the same reference numerals, even if these parts can be configured differently in Figures la-lg and Figures 4a-4e .

[0137] The lock 420 differs from the lock 20 in that the lock 420 is not configured as a cam lock, but as a special-shaped cylinder, which has a blocking protrusion 444 connected to the cylinder 426 in a torsion-proof manner, as shown in Figure 4a . The blocking protrusion 444 can optionally be held in a given position by means of a spring 445 when the lock 420 is not operated. The lock housing 422 now has the shape of a special-shaped cylinder, so that the lock 420 can be used instead of a conventional cylinder lock.

[0138] The lock cylinder 426 has a lock profile 440 at a first end accessible from the front 28 of the lock 420. This lock profile is configured as an inner profile, for example, a quadrilateral recess. The key 402 correspondingly has a fitting portion 406 having a key profile 408 in the form of a protruding outer profile that matches the lock profile 440. Alternatively, the lock profile 440 may also be configured as an outer profile, for example, a quadrilateral protrusion, and the key profile 408 may be configured as an inner profile, for example, an inner quadrilateral profile.

[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 corresponding edge sides of the lock housing 422. The locking elements 454 are capable of being in a locked position within the corresponding receiving portions 456. Figure 5d ) and release position ( Figure 5e The locking element 454 moves between the lock cylinder and the lock housing 422. In the locked position, the locking element 454 engages in the corresponding recess 458 of the lock cylinder, and when the key 402 with the matching magnet structure 412 is inserted, the locking element 454 moves into the released position and releases the rotation of the lock cylinder 426 in the lock housing 422.

[0140] In this embodiment, the lock cylinder 426 is constructed in two parts, having a core 427 disposed in an internal channel 424 of the lock housing 422 and a profile 439 having a lock profile 440. The core 427 and the profile 439 are connected to each other in a torsional manner, such that the outer profile 470 of the core 427 is shaped-fitted into the inner profile 471 of the profile 439, and a bolt 50 passes through the core 427 and is screwed into the internal thread 472 of the profile 439.

[0141] The lock profile 440 and key profile 408 are constructed asymmetrically, so that the key 402 can only be attached to the lock profile 440 along a given orientation. This is achieved by means of a locking element 452 comprising nine locking elements 454 constructed as magnets in this example, and corresponding nine magnets 414 of the magnet structure 412, in this way 2 oriented relative to the magnetic pole directions of the magnets. 9 = 512 different possible combinations.

[0142] The magnetic pole directions of each magnet 414 or locking element 454 are partially indicated by "N" in the accompanying drawings.

[0143] (Magnetic North Pole) and "S" (Magnetic South Pole) are used to indicate this.

[0144] As in lock 320, in lock 420, the receiving portion 456 and the associated recess 458 for the locking element 454 also have different distances from the rotation axis of the lock cylinder 426 (see...). Figure 5c Figure 5d) in order to prevent that the locking element 454 can reach into the further accommodation 456 and thus into a locking position which can prevent the turning of the lock cylinder 426, for example back into the initial position, when the lock cylinder 426 is pivoted.

[0145] In the lock 420, the retaining element 462 is configured as a ring-shaped plate made of ferromagnetic metal which is inserted into the profile piece 439.
