Abstract: A closure system having card keys (K) which are adapted to be issued in coded form, the broad-side surfaces of which are divided into individual fields (E) which can be differently magnetically coded for the individual locks/card-holders and move correspondingly positioned magnetic locking pins (31) as tumblers of the lock (4) into open position; for the broadening, in particular, of their purpose of use, a service station (SA) re-codes data identification individual fields (E1) of the key (K), increasing or decreasing their value, and an evaluation station is provided having a reader for noting and storing these re-codings in association with other codings of the card key (K).

Abstract: A closure system composed of a lock and several keys in which the closing of the lock, determined by magnetically controlled tumblers can be modified by a repositioning of at least one tumbler member within the lock to the code of a subsequent key, and in order to obtain a solution which is particularly advantageous with respect to construction and security, the tumbler member (33, 33') is developed as an adjusting part associated with the recoding magnet (42, 43, 44, 45, 46, 48, 49) in such a manner that the tumbler insertion opening (40, 50, 51) for the recoding magnet can be displaced out of the aligned position with respect to the recoding magnet.

Abstract: The present invention relates to a magnetic card lock with key card which can be inserted into an insertion shaft with gripping opening, the key card being first insertable up to a first stop position, and in which position the key code is requested, and thereupon displaceable by an actuation distance up into the second stop position; in order to obtain a solution which is particularly easily manipulated, it proposes that the broad surface of the key card on its end facing away from the direction of insertion have a visibly differentiated first partial surface (100) which fills up the surface of the gripping opening (107) and is visible in the second stop position.

Abstract: A lock with locking function released by inserting a key card with a magnetized region, in which the end edge (8') of the key card (8) drives a slide (25) which is released by the magnetic tumbler pins (31). There is at least one member which is displaceable by the movement of the slide, one end of the member scanning a profile of the key card (8). The member comprises a pin (62) which is tapered on both ends, the pin being displaceable parallel to the tumbler pins (31) in a borehole (61) in the slide (25) within a region which is free of the magnetic tumbler pins (31).

Abstract: A device for coding key cards for magnetically operating locks and the incorporating of such a device which is as simple as possible plus the corresponding key cards in an entrance control system.

Abstract: The invention refers to a system for the use of locks of hotel room doors, lockers of bathhouses or similar facilities, having a central delivery station located in the region of an entrance station of the hotel, bathhouse or the like for the issuance of locking elements (keys) each of which fits a given lock of the different doors, lockers or the like, and a locking-element return device which is located in the region of an exit station and scans the locking element and evaluates it, for instance, with respect to a change for use, said return device being connected for data to the delivery station, and in order to obtain optimum handling, it proposes that the locking element bear an additional code (for instance a bar code) in order to trace its path of use.

Abstract: A closure system consists of lock and several keys in which the closing of the lock, determined by mechanically or magnetically controllable tumblers, is variable in such a manner that a closure code of the lock which corresponds initially to the coding of the first key can be varied by rearrangement of at least one tumbler element (28) within the lock, in response to the coding of a successor key. This negates need for a tool or hand knob. Displacement of the tumbler element (28) be effected by means of the corresponding successor key (36) in the manner that successor keys (36) are divided into a first region (A) associated exclusively with a closure code of the tumblers and a second supplementation region E which enters into action when the first region agrees with the closure code of the tumblers. This shifts the tumbler element (28) into the position acted on by the supplementation region of the next successor key.

Abstract: A locking device on doors is provided with inner and outer escutcheons (2, 3) and having a lock (5) which is arranged between the two escutcheons to permit actuation from the inside and outside. In order to obtain a substantial advantage by remote inquiry of the locking condition and/or storage of locking conditions which have taken place, the locking device has a simple construction, including at least one switch disk (19, 19a) which is entrained upon the actuation of the lock and contact or switch (S1, S2) associated with the switch disk in order to produce electric recording signals concerning an actuation of the lock and/or inside and outside interrogation takes place.

Abstract: A permutation lock, particularly for storage compartments, has a variable combination such that an opening combination corresponds to a combination to which the lock was set by advancement of the bolt into the locked position. The lock has an emergency opening mechanism which can be activated and deactivated by key actuation. To increase the security value with simple actuation of the permutation lock, the emergency opening mechanism can be deactivated only by means of a reactivation key which can be inserted into a lock cylinder.

Abstract: The invention concerns a system for the unsupervised control of the use of lockers or the like in bath houses, reading rooms, hotels or the like in which the locker doors are provided with a deposit lock; in order to optimize the possibilities of variation while retaining the most favorable structural shape, the locks are operated with codes such that the deposit locks can be brought into the position of readiness to receive a code and store the code and the memory is automatically erased upon the return of the deposit coin.

Abstract: The lock housing has a slot in a top wall via which a coded card key can be inserted to bring into alignment coded magnetic areas on the card with magnetically responsive elements of the lock to unlock the locking mechanism and enable rotation of either a knob or lever arm to open the door. The card moves a spring actuator against a coupling spline to engage it with a spindle spline carried by a shaft interconnected with the knob or lever arm handle. The sliding coupling spline is integral with parts which interrelate with the door lock mechanism such that rotation of the knob or lever arm will now effect release of the door locking mechanism. When the card is fully inserted, the mechanism is maintained in the unlocked condition and the card may be released to turn the knob or handle with the same hand. Spring-loaded members separate the coupling and spindle splines as the magnetic card key is withdrawn from the housing slot.
