Description

The present invention relates to an electronic card lock

  magnetic, this lock comprising two parts or sets, one being mounted on the outside of the door or area to be protected and the other on the inside of the latter, each set being designed to be able to use different cards bearing a different digital code for each of them and / or with a delayed opening command, also separate for each card, this electronic lock being designed to be able to use any

  type of bank, credit, commercial, business, airline, etc. card

  Currently, known locks, which are controlled or actuated by means of magnetic cards are based, as regards their operation, on the passage or introduction of a specific card, which is recognized as valid, and capable of give the information necessary to activate an electromechanical element which

  will cause the opening or closing of a bolt or bolt.

  The major disadvantage of these known types of locks is that they are suitable only for a specific card or for types of cards.

  which are previously designed according to these locks.

  To overcome this major drawback of these known locks, the present invention relates to an electronic lock with a magnetic card and / or a protective keypad, when such a keypad is recommended, and whose operation is based on the passage of a magnetic card of any type, for example of the standard ISO and JIS-III type, which carries some engraved information, but not just any. In addition, this card can be supplemented with the marking of a code, by means of the decimal keyboard, so that the sum of these two combinations sets in motion the electromechanical element.

  to open or close the door on which the lock is placed.

  Furthermore, the object of the present invention is to provide a high security means intended to be used for opening or closing doors. This means can be installed on access or entry doors, interior doors, garage doors etc ... and, preferably, on the doors of armored rooms and vaults, as well as in general , in all sites where access is restricted and where a high degree of security is required and where it is necessary to be supplied by the electrical distribution network. The lock according to the present invention has obvious advantages over the known technique. By its autonomous operation by means of a supply by electric batteries, it is extremely simple and safe. This electronic card lock

  magnetic card is adapted to work with a card of any class.

  It is not necessary to use a special card because normally all cards of

credit or banking are valid.

  It is possible to memorize many different cards such as bank, credit, commercial, corporate, airline, etc. cards so that

  each of them is additionally provided with a separate numerical code.

  In addition, with this lock according to the invention, there is the possibility of having a delayed opening of one to ninety-nine minutes, programmed by the own user. After having memorized a card, one memorizes its numerical code and, if one

  you can program a delayed opening for this card and its code.

  Other advantages of the lock according to the invention, in addition to those which have just been stated, can be deduced from the following possibilities: a) this electronic lock will be blocked if an attempt is made to operate it with a code or a card different or not valid. This blocking is programmable from one to ninety nave minutes. The invalid card number or code used for this attempt is also programmable for a period of one to thirty six

minutes.

  b) this electronic lock incorporates a circuit for detecting the incorrect closing of the locks, this circuit being adapted to notify, acoustically and optically, of

  this poor closure and again cause the actuation of these locks.

  c) this electronic lock controls the state of the supply voltage and acoustically and acoustically advises the state of the batteries, that is to say when they are almost discharged and unsuitable for controlling the 'opening, as well as closing; and if the state of these batteries is too low, we can have a power supply

  external direct current (batteries) or alternative (125 or 220 volts).

  d) this electronic lock has an input for an external alarm and, in

  if it is and in action, it is completely blocked during all this action.

  e) this electronic lock also has an alarm output for activating an external alarm in the event of operation of the lock or opening by

coercion or violence.

  f) this lock also includes, optionally, an internal acoustic alarm of 110 db which is triggered in the event of unauthorized operation,

  mechanical stress and / or vibration, and / or as a function of temperature.

  g) this lock allows a staggered leveling of operation for the different cards and codes that it accepts. h) this lock has an information output for its treatment from the outside, such as the last openings or closings, the indication of the time, the

  date and level of staggering of the code used.

  i) this lock is also suitable for keeping for more than forty years, all the operating information of the cards and programmed combinations, at the

  when electrical energy is lacking.

  j) this lock incorporates an internal key allowing the blocking of its functions.

  k) this lock consumes zero electrical energy. In the waiting condition, it does not require any power to maintain the information stored. More specifically and in accordance with the invention, this lock is remarkable in that it comprises two associated and cooperating elements, one of them being mounted on the outside of the door equipped with this lock and provided with information input elements of the lock, as well as indications of state and of operation thereof, while the other of these elements is mounted on the inside of the door and comprises the elements of control of this lock; The external element comprises a metal envelope incorporating an internal magnetic reader, suitable for reading the corresponding magnetic strip of cards, this metal envelope also comprising a decimal keyboard adapted for the manual introduction of information, as well as a circuit for setting action adapted to be able to put into operation all the circuits of this lock when a card is inserted, and a status indicator circuit comprising three indicator lamps which show the operation of the lock and the state of the power supply thereof this; the control elements of this lock, mounted on the inside of the door, include an electronic circuit provided with two respective position detectors of the blocking locks, as well as an element for actuating these locks, and an internal key for activating or blocking this lock, as well as an autonomous power supply module

  electric by electric batteries which is housed inside the external element.

  Furthermore, the metal casing of the external element also houses an acoustic element, or buzzer, which indicates the errors produced, as well as the state of the electrical supply, this casing also comprising an input for an adapted external electrical supply. to provide power in the event of internal power depletion or

in case this is missing.

  In addition, this lock includes a stopper mounted on the corresponding support of the locks, this stopper being adapted to contact one or the other of two microswitches provided for controlling the lighting of the warning lamps signaling

the corresponding food.

  Other characteristics of the present invention will appear from the following description

  of an embodiment of an electronic lock, given by way of nonlimiting example and shown schematically in the accompanying drawings, in which: - Figure 1 is a front view of the outer metal casing of the lock and in which envelope we see, by transparency, a magnetic reader, an actuation circuit and a buzzer (acoustic element) which is housed inside ;, - Figure 2 is a cross-sectional view of the envelope taken along line AA in Figure 1; - Figure 3 is a cross-sectional view of the envelope taken along line B-B of Figure 1; - Figure 4 is a rear view of the door which allows the observation of the elements of

  control of the lock, this door being in the closed position.

  The electronic magnetic card lock, in accordance with the invention and the protection of which is recommended, consists of two assemblies, one of which is mounted on the outside

  of a door or the area to be protected and, the other, on the inside of this last.

  As can be seen in Figures 1 to 3, on the outside of the door are located the information input elements of the lock and the indicators of its state and operation which are housed in an envelope metal 1 may be provided with a handle or a button (Figures 2 and 3) located at the lower longitudinal edge 10 of this envelope. Inside this envelope are located: a magnetic reader 2 which is responsible for reading the information on the magnetic strip of the cards and for supplying this information to a microcontroller, also located inside and suitable for processing this information ; a decimal keyboard 3 adapted for manual input of information; an actuation circuit 4 designed for putting all of the circuits into operation when a card is inserted; a status indicator circuit comprising three indicator lamps 5, 6, 7 which show the operation of the lock and the state of the power supply; an acoustic element 8 (buzzer) which advises of the general operation, of the errors produced and of the state of the electrical supply; and an input of the external electrical supply 9 to supply this supply in the event of an exhaustion of the internal electrical supply or in the event that

this is lacking.

  FIG. 4 shows the interior of door 15 on which are installed the control elements of the lock which are responsible for processing the information received from the exterior of the door and for acting, depending on the result of this processing, on the bolts or latches 14 or on the

  blocking of these and, in addition, controlling the secondary functions of the circuit (alarms).

  These control elements consist of an electronic circuit 10 provided with detectors of the position of the bolts or latches 14; an element for actuating these bolts or latches 14 which may be constituted by a motor 11; an internal key 12 for activating or blocking the electrical supply of this set of elements; a module 13 for supplying power to the lock constituted by batteries or, optionally, by a transformer circuit of the alternating current; and the aforementioned bolts or latches 14 of the door. To close the door (FIG. 4), the magnetic card is inserted so that it slides in the groove R of the metal casing 1 so that it activates the circuit 4 and that, following its displacement from left to right (relative to Figure 1), the reader

  magnetic 2 collects the information and sends it to circuit 10.

  At this stage, if the card is correct, this circuit 10 interprets this information and sends electric current to the motor or actuation element 11 which transforms electrical energy into a mechanical force which causes the latches 14 to move from the left around the

  right (compared to figure 4) to close the door.

  Circuit 10, still in the case of processing a correct card, sends electric current to lamp 7 (red in color) which indicates that the locks have been moved to

close the door.

  In the case where the locks encounter any obstacle in their programmed closing stroke, the circuit 10 sends current to the motor so as to reverse its direction of rotation, which direction caused the support 14a of the locks and the stop d 'stop 16 which is provided so that this stop comes into contact with the microswitch 17, so that the reversal of this direction of rotation causes the recoil of the support 14a and, consequently, of the stop 16 until 'so that it comes into contact with the other microswitch 18 and causes the lamp 5 to light (green in color). The orange lamp 6 is used to warn of the state of the electric batteries. This lamp 6 is subjected to the action of the magnetic card which is slid into the groove R of the envelope 1. If the electric batteries are in perfect condition, this lamp 6 is not lit. On the other hand, if the state of these cells or batteries is deficient, this orange lamp is lit intermittently for a few seconds. In this situation, the door can be opened and closed several times but, when the batteries are empty, the last operation which is possible to open the door, but not the lock, is to proceed

  necessarily and immediately upon recharging the electric batteries.

  To open the door, the same sequential process is applied. The lamp 7 (red) lights up for a minimal time, the circuit 10 interprets the information and, if the card is correct, sends current to the motor 11 which causes the latches 14 to move from the right to the left (relative in figure 4) and the lamp 5 (green) lights up during the movement

of these locks.

  In general, the operation of the electronic lock according to the invention is defined below according to two forms of use: only a card reader is used,

  or a card reader and a decimal keyboard.

  When only magnetic cards are used, the operation (with the door in the open position) is as follows: a) To close the door, pass any magnetic card (on which information is engraved), this card is recognized by the lock which excites the closing circuit (motor) indicating the operation by means of the lamp 7

red. The door is then closed.

  b) To open this door, you must pass the same card with which the closure was ordered. The green lamp 5 lights up and the latches are released from their position

  closing while moving. Then we can open the door.

  c) To program other cards, with the door open, you must pass the master card, then listen to several programming tones after passing the cards you want to memorize. Afterwards, we order the closure with any

which of these cards.

  d) To open, pass any of these memorized cards and the door opens normally. When using a magnetic card and a decimal keypad, the operation of the lock (with the door open is as follows: a) To close the door, pass any magnetic card (which is provided with engraved information) and this card is recognized by the lock. Press the keys on the keyboard to form a combination of four to ten digits and the closing circuit (motor) is energized, this excitation being indicated by the lighting of the

  lamp 7 red. The door is then closed.

  b) To open, the same magnetic card is used as for closing. The keys on the keyboard are pressed to form the same combination as for closing and the green lamp 5 lights up, the latches disengaging from their closed position in

  moving Then we can open the door.

  c) To program other cards, with the door open, pass the master magnetic card and then listen to several programming tones after swiping the cards you want to memorize. For each of them, a code of four to ten digits is marked on the decimal keyboard. After we order the closure with

any of these cards.

  d) To open, pass any of these memorized cards which is marked

  of the code that was memorized for it. The door can then be opened normally.

  We will now describe the operation of this lock subjected to a delayed opening.

  To program this delayed opening, when you use only one card, the door being in the open position, you pass the master card on which is programmed the time of

desired delay for opening.

  a) To close the door, you pass any magnetic card (provided with engraved information), this card is recognized by the lock which excites the closing circuit (motor or electromagnet) indicating the operation by the intermediary of

  the lighting of the red lamp 7. The door is then closed.

  b) To open, you pass the same card as for closing. The green lamp 5 lights up intermittently and, when the opening delay time has passed, the latches disengage from their closed position by moving. Then we can

to open the door.

  c) To program the delayed opening when using a card and the decimal keyboard, pass the master card to memorize other cards and, after marking each numerical code from four to ten digits, mark the time of

  opening delay for each card from one to ninety-nine minutes.

  For each card that has been memorized, we repeat the following process: a) To close the door, we pass any of the cards (which is provided with engraved information), this card is recognized by the lock then we mark the code from four to ten digits on this card and the closing circuit (motor) is energized, the operation being indicated by the lighting of the red lamp 7. The door is

then closed.

  b) To open, pass the same card as for closing, or any of the other memorized cards, then mark the digital code on the keyboard, the green lamp 5 lights up intermittently and, when the opening delay time has passed, the latches are released from their closed position by

  moving. The door can then be opened.

  Ultimately, when any handling error occurs, or when invalid cards are used, the red lamp 7 lights up and an error tone is heard; when the batteries are discharged, the orange lamp 6 lights up intermittently and we

  also hears an error tone.

  It is considered that the above description is sufficient for a technician in the

  material includes the features of the present invention and the advantages which

flow from it.

  The materials, shapes and dimensions, as well as the arrangement of the elements of this lock

  are subject to variations without departing from the scope of the present invention.
