Definitions

  • the present invention relates to a lock system, and in particular to a lock system intended for locking rooms to which a limited number of persons are permitted access over spaced periods of time.
  • Such rooms may include hotel rooms, safes and drink cabinets placed in hotel rooms for use by guests, and also a diversity of storage facilities placed at the disposal of selected persons for a limited period of time, such as dress- changing rooms, banks and post offices.
  • lock systems which, instead of conventional keys, incorporate the use of magnetic cards, on which a digital code can be magnetically registered, and locks which include an electrically operable locking mechanism, a magnetic-card reading means, a memory in which a digital code can be stored, and means for making a comparison between the digital code read by the card reader from the magnetic card, serving as the "key", and the code stored in the memory, whereupon the locking mechanism is unlocked, provided that there is agreement between the two codes compared.
  • lock system a key card is provided with magnetically registered data including a lock identification allotted to a specific lock, a validity time for the card and a randomly selected ligitimacy code allotted individually to the card, and each lock comprises a locking mechanism having electrically actuable means for unlocking the same, a magnetic-card reader arranged to receive a card of the aforementioned kind and to read the data registered thereon, a memory containing said lock-identification data and capable of storing card data of the aforementioned kind, comparison means for comparing the data stored in said memory with data read from said card by means of said magnetic-card reader and for acting upon the locking mechanism in response to said comparison, and a programming unit for entering data into said memory and for changing the data content of said memory.
  • lock systems for hotel rooms and similar applications it should preferably be possible to issue cards to members of the hotel staff, for example cleaning personnel and hotel security personnel, which cards can be used for opening the locks to a given number of specific rooms only on certain weekdays and/or during certain times of the day.
  • the central card issuing unit which is normally located in the reception of the hotel, must comprise a data store in which all the legitimacy codes of all issued current cards are kept stored. Otherwise, it is not possible to issue any new cards, which can be used for opening and reprogramming the individual locks. This creates a very serious problem, especially if the synchronisation between the card data stored in the central unit and the card data stored in the individual locks is lost or if the legitimacy codes stored in the central unit are for some reason lost. In such situations it will not be possible to issue any new cards capable of opening the locks of the system.
  • the object of the present invention is to provide an improved lock system of the aforementioned kind, which has an improved utility and provides a more simple way of issuing new cards at any time, without any central data store for the legitimacy codes of previously issued cards being required.
  • the lock system according to the invention affords several important advantages. For examples, it is possible to establish accurately the validity time of each card in real time, not only with respect to an initial date and a final date but also with respect to those days and those times of day on which the card can be used within the interim period. Thus, it is possible to issue a card which can be used only on certain weekdays and/or during certain times of the day, while at the same time it is possible to establish a total card validity time, i.e. a first and a last day of validity. It is also possible to issue a card long beforehand, i.e.
  • a new card can be issued at any time for any given lock, even if the validity time of a previously issued card for the same lock has not yet expired, and the system does not require, for this purpose, any central data store in which the legitimacy codes of previously issued cards are stored.
  • lock system according to the invention is described, by way of example, with respect to its use in a hotel, although it will be understood that a lock system according to the invention can also be used to the same advantage for many other types of institution, and that the magnetic cards serving as keys can be of another kind with respect to the different usages for which they are legitimized.
  • Figure 1 illustrates schematically and by way of example a conventional magnetic card 1, which can be used as a "key" in a lock system according to the invention and which is provided with, for example, a strip 2 of magnetisable material on which data, preferably in digital form, can be magnetically registered.
  • the magnetic registration, or the writing of data into the card is effected by means of a separate, conventional programming or write-in apparatus (not shown in detail) which is suitably placed in the reception facilities of the hotel.
  • the aforementioned programming or write-in apparatus can be arranged to issue or to program different types of card.
  • the aforementioned programming or write-in apparatus can be arranged to issue or to program different types of card.
  • three main types of card namely: guest cards, which are intended for issue to hotel guests, and to afford each guest access to only one given room during all times of the day for a specific, selectable period of time, validity time;
  • service cards which are intended for cleaning personnel and other personnel, and which afford access to a given floor, during a certain time of day, for example between 8.00 and 17.00, and/or on certain days of the week, for example all weekdays, and for a given validity time, i.e. from a first validity day to a final validity day;
  • master cards intended for the hotel security staff or management, which afford access to all rooms in the hotel or in a certain part of the hotel at all times of the day for a given validity time, i.e. from a first validity day to a final validity day.
  • the data registered magnetically on the card, preferably in digital form, by means of the programming or write-in apparatus may comprise the following information:
  • the programming or write-in apparatus is designed so that when issuing or programming a card, the operator is able to determine the type of card concerned, the system identification, the lock identification, and the validity time, but not the legitimacy code randomly selected by the apparatus itself.
  • the apparatus is designed so that it can only be operated by selected, authorized personnel, which may have varying grades of authorization, such that, for example, the system identification can only be determined and changed by a few people, which may also apply to the issue of a master card, for example.
  • the lock illustrated in the block schematic of Fig. 2 includes a conventional magnetic card reader 3, for example a reader of the Magdat-type MSC-170-IR, or the Ericsson-type KDT 30201, into which a magnetic card 1 according to Figure 1 can be inserted, and which reads the data magnetically registered on the card.
  • the lock also includes a conventional locking mechanism 4 which can be operated electrically between a locked and an unlocked state.
  • the lock includes a legitimacy comparator 8, a time comparator 9 and a programming unit 10, the functional purpose of which will be made apparent hereinafter.
  • the lock may also incorporate a position sensor 5, for example in the form of a microswitch, which detects the position of a lock bolt in the lock mechanism 4.
  • the memory 6, which is suitably of the direct access type, is suitably arranged to store digital data. This data can be changed with the aid of the programming unit 10.
  • the aforementioned system identification and the lock identification pertaining to said lock are always stored in the memory.
  • the aforesaid items of data are entered into the memory 6 before the lock is installed by, temporarily connecting the lock to the aforementioned programming or write-in apparatus from which the system identification and lock identfica- tion is obtained, and entering said data into the memory 6 through the programming unit 10.
  • the legitimacy comparator 8 is arranged to receive from the card reader 3, the data or information registered on the magnetic card fed to the card reader 3, and to compare this data with data stored in the memory 6.
  • the time comparator 9 is designed to be able to make a mutual comparison between the real time given by the real time clock of said lock, the time-information read from an inserted card by the card reader 3, and time-information stored in the memory 6.
  • a guest card of the kind aforedescribed i.e. a card bearing registered data concerning the type of card, system identification, validity time, and a randomly selected legitimacy code.
  • a microprocessor (not shown in detail) incorporated in the lock and being, for example, of the aforementioned kind designated AIM65 from Rockwell instructs the time comparator 9 to compare the validity time read from the card with the real time given by the real-time clock 7, and further instructs the legitimacy comparator 8 to compare the system identification and the lock identification in the data read from the card with the system-identification data and the lock-identification data previously stored in the lock memory 6.
  • the programming unit 10 is ordered to store all the data registered on the card in a site in memory 6 intended herefor, and actuates the lock mechanism, to open the lock. If, on the other hand, one of the comparisons shows a negative result, the lock remains locked and no further action takes place. Thus, the lock cannot be opened with a guest card unless the card is intended for the location and the lock in question, and unless it is presented to the lock within the validity time registered on the card.
  • the time comparator 9 is instructed to compare the time given by the real-time clock 7 with the validity time stored as described above in the site in the memory 6 reserved for guest-card date. If the result of this comparison is positive, i.e. the validity time stored in the memory has not yet expired, the legitimacy comparator8 is instructed to comparethewhole of the data read from the card with the data stored in the aforesaid manner in the memory 6, in the site reserved forthe guest-card data. If the comparison shows agreement between the two sets of data, the legitimacy comparator 8 actuates the lock mechanism 4, to open the lock.
  • the programming unit 10 is instructed to erase the validity time stored in the memory 6, wherefore the subsequent comparison made by the legitimacy comparator 8, as described above, between the data registered on the guest card and the guest-card data stored in the memory 6 will also give a negative result, whereby the lock is not opened. Consequently, the card can not be used to open the lock, when the validity time registered on the card has expired.
  • a guest may decide to vacate his/her room earlier than was initially intended, i.e. before the validity time of the card issued to the guest has expired. Similar circumstances may occur with other types of institutions or established organizations. In such cases, in order to enable a new guest to enter the room, it is necessary to issue a card which will be accepted by the lock, despite the fact that the memory 6 of the lock has stored therein data relating to a guest card whose validity time has not yet expired.
  • the procedure adopted differs from that taken with the aforescribed guest card, insomuch asthe new master card is not given a special override code.
  • the lock is so designed that the legitimacy comparator 8 accepts such a new master card, provided with a longer validity time than the validity time previously registered in the memory 6 of said master card, and in conjunction therewith substitutes the master card data previously stored in said memory with the data found registered on the new master card.
  • the data registered on a service card contains no randomly selected legitimacy code, but only data referring to system identification, lock identification, i.e. identifications of those locks or rooms to which the service card has access, and a validity time.
  • the lock functions in the above-described manner, with the exception that none of the data registered in the service card is stored in the memory 6 of the lock.
  • the legitimacy comparator 8 solely checks the system-identification data and the lock-identification data on the card with the system and lock identification data stored in the memory 6, while the time-comparator 9 checks the card validity-time with the real time given by the real-time clock 7.
  • a lock system is designed to enable the system identification to be changed, by issuing a new master card which contains both the old and the new system identification, and also a special operation code.
  • the lock detects said operation code and the programming unit 10 in the lock is ordered to replace the old system-identification data stored in the lock memory 6 with the new system-identification data registered on the new master card.
  • the position sensor 5 of the lock illustrated in Figure 2 may be arranged to sense a special position for a lock bolt in the lock mechanism 4, to which the lock bolt may be moved manually by the hotel guest from inside the door.
  • the position sensor 5 acts upon the legitimacy comparator 8 in a manner such that said comparator no longer accepts, for example, a service card, but only master cards and guest cards. This function can be employed when a guest does wish to be disturbed.
  • the safe lock can be designed so thatthe position sensor 5 is constantly activated, whereupon the safe can only be opened with a guest card and a master card.
  • the position sensor 5 may also be arranged to act upon the legitimacy comparator 8 in a manner such that the comparator will not accept a guest card provided with an override code of the aforementioned kind.
  • the magnetic card 1 can be reprogrammed and used a repeated number of times, simply by presenting the card to the aforedescribed programming and write-in apparatus each time the card is to be renewed.
  • the programming and write-in apparatus is advantageously designed to record therein the number of times an individual card has been renewed and fresh data registered therein. In this way, it is possible to estimate when a card has been used so many times that there is danger of it being worn to such an extent as to render the card unserviceable and unreliable.
