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.
Claims20
A system for the use of locks in lockable facilities including locks of hotel room doors, and lockers of bathhouses, the system comprising
- a central delivery station located in a region of an entrance station of a lockable facility for the issuance of locking elements, each of which fits a given lock of respective doors, each lock having a magnet pin combination;
- lockers, an exit station, and a locking-element return device which is located in a region of the exit station and for scanning a locking element and evaluating the locking element, the return device being connected for data to the delivery station;
- and wherein
- the delivery station comprises;
- a store of locking-element cards, the cards having differing identifiers;
- a magnetization device which polarizes a locking-element card in regions corresponding to a magnet-in combination of a locker lock;
- a memory coupled to the magnetization device, the memory storing magnetization combinations corresponding to the respective identifiers;
- and
- an erasing device;
- the return device comprises an identifier scanning device which activates the erasing device of the delivery station to erase from the memory a stored corresponding magnetization combination to free the magnetization combination for a new issue of card and assignment to a new identifier of the card;
- a locker lock comprises a pusher and a set of permanent magnets movable within openings of the pusher from a blocking position, the pusher being movable into a lock-open position,
- a command key insertable into the locker lock for moving the pusher, and wherein
- the locker lock has a magnetic coding formed of individual ones of the permanent magnets which are arranged in openings of the pusher and liftable out of their blocking position by means of correspondingly positioned magnetization regions of a key brought into a position parallel to the pusher, whereupon the pusher is shiftable into a lock-open position, a part of the permanent magnets being developed as recoding magnets which are displaceable relative to a broad surface of the pusher from one position into another so as to change the magnetic coding, displacement of at least one of the recoding magnets taking place in synchronism with displacement of the pusher by means of the command key.
