    The invention relates to a lock cylinder with housing and rotatable therein, a keyway having cylinder core, wherein at least one movably arranged, movable by a magnetic force sensing element and at least one scanning the position of the sensing element sensing element are provided which cooperates with at least one latching element of the lock cylinder to to cause the unlock or lock.
    The invention further relates to a key with a Reide and a key bit.
    Locking cylinders of the type mentioned, so-called magnetic locks are known and described in detail, for example. in AT-PS Nos. 341901 and 357430. Essential features of these and similar locks are tumblers or query elements in the form of magnetic rotors whose rotational position corresponding to the magnetic encoding associated key magnets is adjustable, the correct rotational position of the magnet rotors are scanned by sensing elements of the castle. At the correct rotational position, the sensing element can be inserted into a recess of the magnet rotor and the sliding movement in turn controls a blocking element which causes the lock of the lock or allows a rotation of the lock. The direction of movement of the scanning element can have any direction and in practice runs predominantly in the direction of the radius of the magnet rotor, but can also run in the axial direction of the magnet rotor. Such locks can be cylinder locks or sliding locks. In the case of cylinder locks, the magnet rotors are mounted in recesses of the cylinder core and the mentioned scanning elements act on the one hand with the magnet rotors and on the other hand
    * * Together with locking elements of the cylinder housing together to effect the unlocking or locking.
    A disadvantage of the magnetic locks described is the fact that emanating from the key magnets arranged in the key a strong magnetic field, which is able to affect the magnetic encoding of example credit card-shaped magnetic cards. In particular, when such magnetic keys come to rest for a long time in the vicinity of the magnetic stripe of such cards, there is the danger of a complete loss of the magnetic-coded map data.
    The invention therefore aims to improve magnetic locks of the type mentioned in such a way that no possible magnetic field emanates from the key, but at the same time the extremely high security and coding diversity of magnetic locks should be maintained.
    To achieve this object, the invention consists in a lock cylinder of the type mentioned essentially in that the lock cylinder, in particular the cylinder core of the query element different means for generating a key channel passing magnetic flux through which the at least one movably arranged query element is movable , The means for generating the magnetic flux, which is used by the Abfra-elements in the lock cylinder to check the coding of the key, thus, unlike the conventional magnetic locks not in the key, but only in the lock cylinder. The means for generating the magnetic flux are arranged such that the magnetic flux penetrates the key channel, this being the case in particular when the key is inserted into the key channel, the magnetic flux passing through the key being indicated below encoding elements described in more detail of the key is directed so that arranged in the cylinder core, magnetically operating query elements can query the appropriate coding, in the case of an authorized key locking or unlocking is released.
    Preferably, the means for generating the magnetic flux are formed by a permanent magnet. The permanent magnet can be arranged, for example, on only one side of the key channel in the cylinder core, wherein the arrangement is preferably such that a magnetic circuit in the lock cylinder core can be closed with the lowest possible magnetic resistance, so that can be found with a weaker permanent magnet of Auslangen , Preferably, the permanent magnet is in this case the key channel immediately adjacent, so that closes the magnetic circuit with inserted key with the smallest possible magnetic resistance and the reliability can be increased. In this case, areas with higher magnetic resistance in the magnetic circuit, such as the transition point from the lock cylinder core inside to the key can be optimized so that the lengths of these locations are kept as small as possible. According to a preferred embodiment, the permanent magnet in this case has a rectangular cross-sectional shape.
    In order to minimize stray magnetic fields in the cylinder core, a preferred embodiment provides that the cylinder - 4 - * - * * * t * ** * * * * * * * * * * *
    * · V core, in particular the cylinder core jacket consists of a high magnetic resistance material, in particular of a material, e.g. Brass, which has a higher magnetic resistance than iron. The magnetic circuit can be closed in particular with the lowest possible magnetic resistance if, as it corresponds to a further preferred embodiment, the cylinder core has at least one region of ferromagnetic material which cooperates with the permanent magnet to form a magnetic circuit.
    The interrogator element movable by the magnetic flux passing through the key channel is preferably formed by a magnet rotor. A magnetic rotor here is to be understood as meaning a rotating component which has a ferromagnetic material or a permanent magnet and which is aligned with the magnetic field lines passing through the key channel in such a way that the rotor aligns with the flux lines in a predetermined rotational position. Preferably, a plurality of movably arranged, movable by a magnetic force query element along the longitudinal extent of the key channel are arranged. The higher the number of query elements, the greater the maximum number of different key encodings. The query elements may in this case be arranged only on one side of the key channel. Particularly preferred is an embodiment in which the interrogation elements are arranged on two opposite sides of the key channel, so that as large a number of query elements can find space even in the smallest space.
    The invention further provides a key of the type mentioned at the outset, which according to the invention is developed in such a way that the key bit consists of a material with high magnetic resistance and is penetrated by at least one non-magnetized region of lower magnetic resistance the key surface forms at least one flow entry point and at least one flow exit point. The term " not magnetized " This also includes a possible low magnetization, as it can occur, for example, as a result of remanence phenomena. It can thus be seen that the key has no or only weakly magnetized material, so that no significant magnetic field originates from the key, which could impair, for example, magnetic cards. The coding of the key is now carried out such that non-magnetized areas of lower magnetic resistance are arranged in the material of the key, through which, in the key channel inserted key, for example, from the permanent magnet of the cylinder core starting magnetic flux is passed. The arrangement of the non-magnetized and formed with low magnetic resistance key areas and in particular their course and the position and orientation of arranged on the key surface Flussein- and river exit points of said areas determine the respective key encoding.
    The keys passing through, non-magnetized, formed with low magnetic resistance areas can thereby pass through the key, that the field input and the field exit point are arranged on the same key side. However, an embodiment in which the at least one region of lower magnetic resistance is the field entry point and the - 6 -
    Has field exit point on opposite sides of the key. Preferably, it is further provided that the field entry point is arranged offset relative to the field exit point in a direction transverse to the key surface normal.
    The geometric shape of the field entry and exit points as well as their position determine the course and the coupled magnetic flux of the incoming and exiting magnetic field lines, whereby the respective position of the magnetic rotors or the interrogation elements is influenced. A preferred embodiment in this context provides that the non-magnetized region of lower magnetic resistance at the field exit point has a cross section which is twisted in relation to the cross section at the field entry point. In this connection, a further preferred embodiment provides that the non-magnetized region of lower magnetic resistance has a rectangular cross-section at the field entry point and possibly at the field exit point.
    To increase the security against locking, the inventively provided magnetic-acting coding can be combined with other coding possibilities, it being possible in particular for the key to have a mechanical coding, in particular profiling, which can be brought into operative connection with mechanical interrogation elements.
    The invention will be explained in more detail with reference to embodiments schematically illustrated in the drawing. 1 shows a side view of a key according to the invention, FIG. 2 shows a cross-sectional view of a modified embodiment of the key, FIG.
    Cross-section of a lock cylinder with inserted key in the key channel and Figure 4 is a perspective view of a magnet rotor.
    The key 1 shown in Figure 1 has a Reide 2 and a key bit 3. The key bit 3 is made of a high-resistance material and has a plurality of non-magnetized areas 4 made of a lower-resistance material. As can be seen in the cross-sectional view according to FIG. 2, the non-magnetized regions 4 can run in different ways through the key 1, with each region 4 each having a field entry point 5 and a field exit point 6. The field inlet and the field exit points 5 and 6 can here, as can be seen in particular in Figure 2, be arranged on opposite sides of the key or on the same side of the key. As can also be seen in FIG. 2, the non-magnetized regions 4 can run through the key such that the field inlet and the field exit point have a different cross-section, wherein the field entry cross-section, in particular with respect to the field exit cross-section, is arranged rotated around the axis indicated schematically by FIG can be. The key surface may further comprise a field and the field exit points 5 and 6 of the non-magnetized areas 4 covering cover, so that it is not recognizable from the outside, where the individual field and field exit points are arranged. Such a cover may for example consist of non-transparent plastic or the like. - 8 - * * * · • ♦
    The material of the key 1 with high magnetic resistance may be, for example brass, copper, aluminum or a matching plastic. The non-magnetized regions 4 of low magnetic resistance may be made, for example, of a ferromagnetic material such as iron, cobalt, nickel, and their non-permanent magnet alloys, e.g. AlNiCo, SmCo, Nd2Fei4B, ΝΪ8οΚβ2ο, NiFeCo or also from correspondingly modified plastics, e.g. with carbon nanotubes.
    In Figure 3, the rotatable about the axis 8 cylinder core of a lock cylinder is designated 9 and has a keyway 10 on. In the keyway 10, a key 1 is arranged, which has a plurality of non-magnetized regions 4 with low magnetic resistance. In the cylinder core 9, a ferromagnetic circuit 11 is arranged, which can guide the magnetic flux with low magnetic resistance through the cylinder core. In this case, the magnetic rotors 12 are aligned in accordance with the areas with low magnetic resistance in the key, not shown sensing elements query the position of the magnet rotors 12. The sensing elements, in turn, cooperate with a detent element, not shown, of the housing to effect unlocking or locking.
    FIG. 4 shows a preferred embodiment of a magnet rotor 12, wherein the axis of rotation of the magnet rotor 12 is designated as 13 in FIG. The magnet rotor is embodied as a cylinder 14 and is penetrated by a region 15 which, for example, is of cuboid shape and has a field entry or an exit, respectively at the front side of the magnet rotor and at the rear side of the magnet rotor.
    Has field exit point. The region 15 is either designed as a permanent magnet and magnetized so that it aligns by rotation according to the arrow 16 by the respective assigned region 4 of the key 1 passing magnetic field, or the region 15 is formed of a material of low magnetic resistance, the can also align according to the each assigned area 4 of the key 1 passing magnetic field.
    Embodiments are also conceivable in which the ferromagnetic circle in the cylinder core is completely or partially replaced by a permanent magnet and thus the magnet rotors align themselves in accordance with the permanent magnet 11 and the area with low magnetic resistance in the key. This embodiment is particularly susceptible to interference, since a higher field strength is achieved by the many permanent magnets and therefore also the magnetic force acting on the rotors is amplified.
    Embodiments are also conceivable in which the region 11 consists entirely of a permanent magnet, or partially also of a material with a low magnetic resistance. The rotors have areas of low magnetic resistance, thereby aligning the rotors with their areas of low magnetic resistance to the areas of low magnetic resistance in the key and cylinder core. An advantage of this design is that the permanent magnets can be omitted in the rotors and can be replaced by cheaper areas of low magnetic resistance.
