Locking Cylinder

Tb« invention relaies to a lock cylinder aad a key according: to the pr®smbte«fda&» 1.

Lock cylinders, of foe type mentioned jjjp.tho prsmhhlç of claim 1 ate, fOrinstsnee. described in: DE 192 λ 51.5 AL

Leek cylinders, so waited magnetic Socks, ate ktsosm and deserihed So detail, e.g., in Austrian Patenis Nos. M BdI aód dSSíád, Essential characteristic features of these and similar Socks comprise rotary tumblers and/or hnermgator elements in the form of magnetic rotors whose rotational position can be adjusted as a function of the magnetic coding of associated key tnapets, the correct rotabonsd positions of dm magnetic rotors being scanned by scanner elements of the iock. In the correct rotational position, the scanner element can be inserted Into a recess of the mspetlc: rotor, and |b a&ovit»«ai -5^¾ in Sum actuate a locking element causing the locking of the iock or allowing a rotation of the lock. The direction of Movement of the scanner dement may be in any direction and, m practise primarily extends in the sense of the radios ofthe magnetic rotor, yet rosy also extend in the stxlai dlmetion of the magnetic foton Such locks can be cylinder locks of slide locks. In the ease of cylinder looks, the magnetic rotors are mounted sin recesses of the cylinder core, add die above-nsendoned scanner elements interact on ibe one band, svith the magnetic roidrs and, on the biker hand, with latch etemeois ofthe cylinder housing so as to cause locking or unlocking.

The described mopeite locks involve the drawback of a strong magnetic. Seid odgmalmg from the key magnets dlsposeti in foe key, which magnetic field is able to afreet the tnagnetic coding of, ibr instance, magnetic cards similar to check cards, in particular, if hoch magnetic hep bomb to lie hear the meghode ships of such herds Ibr extended periods, this will involve the risk of a complete: loss of the mapetfeally coded card data.

The invention,, dtetelbre, aims to improve magnetic locks of the initially defined kind to the effect that ho magnetic field will: originate from the key. If possible, while the extremely hip safely and coding diversity of magnetic locks will, however, he maintained hi the same time. !'b solve this object, the hxentson in & epthtosbon of a lock cylinder and: a key of the initially döllmd kind essentially consists In thet said iock eyltedet is formed with a honslng; and a cylinder core rotatable Éc:rcin Mtá including a keywtiy, wherein at least otse ibbvably arranged! itiWltogaibr clement capable of being movedrby a% magnetic force and at feast one scanner element scamnng the: posltfett of the Interrogator elemest bib provided^ said scanner elsmeitt cooperating wish at fast one latch element of the lock cylinder to cause ttnlockfeg or locking, wherein the: lock cyiinder, fe parficolar the cylinder cote, meludes means difiltettt Sturt did interrogator etetnem, in generating m mognette :te passing thsbhgk IP leywb# atsd causing the ;st least otte hmvabiy arranged inttsTogator element to move, and wherein the key Is formed wiir a how and a key bit, whereto the key hit is comprised of a material having a high magnetic reslstatiee and is tntefepersed with at least one non-rnagneifred mgibo of lower Magnetic rcsistasp, which #rma at least op field entranec and at least one field Pit on the key surface, wherein, in dm position of the key inserted in the key way, an interrogator clement capable of being: moved fey the magnetic force is each associated to the field exits of Ike nommapetlzed regions of lower tpaghmlc resistance ofthe key.
