Abstract

THE SUBJECT OF THE PRESENT INVENTION IS AN ELECTRONIC MAGNETIC OPENING AND CLOSING SYSTEM OF LOCKS. ACCORDING TO THE INVENTION THE OPENING CODE IS SHAPED BY THE ASSOCIATION OF A SERIES OF SLOTS AND SLOTS SHAPED IN A METAL BLADE 5 WITH PROVISIONAL, NON-PERMANENT MAGNETING PROPERTIES. THE CODE DETECTION MEANS ARE INCORPORATED INSIDE A CARCASE 1 PROVIDED IN THE LOCK AND EQUIPPED WITH A HOLE AND A PENETRATION PASSAGE IN ACCORDANCE WITH THE STRUCTURE OF THE KEY. ON THIS PASSAGE IS PLACED A PERMANENT MAGNET UNDER WHICH ARE PLACED MAGNETIC DETECTORS CONNECTED TO AN ELECTRONIC CIRCUIT, CONTAINING AS THE MAIN ACTIVE ELEMENT, A MICRO-COMPUTER CONTROLLED BY A DECISION LOGIC AND COMMANDING THE OPERATION OF A POWER STAGE WHICH IS USED FOR ELECTRICAL POWER SUPPLY FOR LOCK LOCKING DEVICES.

Description

The present invention relates to a magnetically system.

  tick-electronic opening and closing locks of the type that equips for example the apartment doors and in which the bolts that keep them closed are actuated by means of the introduction of a body that serves as a key, and acts on a set of magnets, which,

  In turn, control electronic components de-

  designed to provoke the electrical supply of relays which make it possible to unlock the bolts which up to that moment kept the door locked, thus allowing access

in the room provided with this door.

  Currently, this type of lock systems

  is widely used and is replacing

  traditional heads of pump locks that use

toothed keys.

  There are currently very complicated mechanical systems on the market, other systems that are electronic and others that are magnetic, and gold currently uses systems that use electrical contacts, power lines, oscillators sensitive to frequency or capacitance, magnetic combinations which generally comprise magnets on which ferromagnetic parts 2 -

  1 based on the use of cards or magnetic tapes

  and the combination of read heads, or the use of magnet-based locks which must act in combination with magnetic "reed" or Hall effect type magnetic detectors

  All currently used systems,

  during use, problems or incon-

  in most of them, the effectiveness of the lock is not total if we use

  nightingales, and there are other systems

  the disadvantage is that the orifices in which are introduced the magnetic keys or magnetic plugs are disabled by the dirt that enters; also it is inevitable that the keys normally used in locks of this type arrive

to be demagnetized -

  In general, the magnetic lock systems and even the mechanical systems or the combination of both have the disadvantage that affects all locks currently known, and that is that the code that allows the opening of the lock is located in the part of it that could be called the female part, that is to say, in the piace, where, to put it better, the whole -3-

  parts which are fixed on the door and which are intended

  n To receive the key through the perforation or opening it

  The location of the key or code in

  this female part allows any expert to access

  der the code or key and therefore O to open the door, either by using nightingales, perforations or simply by removing this set of pieces together female calls and acting on the code that is established

in this part.

  In today's closure systems, which use magnetic detectors, there are two

  obvious problems, the first of which is the glo-

  of the different detectors which is extremely

  it is difficult to finalize and install and the fact that

  Each key must be different for each key, which means that the opening code must be located inside the female part, with the disadvantage of making it easier to access this part indicated above. magnets of this type of locks are located in the cl &

  male part, if this key is demagnetized accidentally

  dentally, even partially, the lock will be inaccessible or to say better unusableo The type of locks commented so far and 4 -

  1 to which the object of the invention also refers, does not pre-

  do not have safety bolts operated directly, as it is normal to install only latches that can be operated easily by electrical means and opposing the force exerted by springs that are

  intended to keep them in a prominent position, ie

  say in locked position of the door.

  Starting from what has been indicated so far and taking into account the disadvantages mentioned,

  one of the main features of the object of the in-

  The invention consists in that the code is not located in the part called the female part of the lock assembly, but on the contrary in the part called the male type part, that is to say the key, and, furthermore, it is not a question of

  key permanently magnetized.

  The subject of the invention, which relates to magnetic-electronic type locks, comprises the key itself, which consists of a series of independent pieces, although they may also be formed by a soft iron blade with slots or dowels. which is intended to act on the female part or receiver O while inside the female part are located magnetic detectors which will preferably be - 1 "reed" or Hall effect contacts, the set of the lock also comprising a single magnet for permanently activating all the contacts in question as long as the introduction of the key does not occur, In combination with what has just been described so far, the lock comprises a device constituted by a printed circuit

  which supports the detectors with a con-

  multiple conductors with two end connectors, one of which is: placed on the printed circuit, while

  the other is installed on an electronic circuit which

  a logic based on a microcomputer and a set

  microswitches, is intended to affect a

  In these conditions, it is understood that when the key or the plug is inserted inside the receiver or the female part, the slots of soft iron absorb

  the magnetic field of one of the detectors that was magnetized

  permanently until the key is penetrated, and therefore, when the soft iron key is inserted, some of these detectors are deactivated, which establishes the code of command, which,

  if it coincides with the code programmed in the micro-interrup-

  allows the microcomputer to power

  It should be noted that when using the structure described so far, the first time

  which will follow from an exemplary embodiment and with reference to the appended drawings, in which: FIG. 1 represents a perspective view of

  two main parts that make up the lock, that is-o-

  As stated above, the mechanisms

  shown in Figures 8, 9, 10, and 11 can be

  born by the magnetic electronic lock that will be described

  This lock will be the one that controls these devices,

  Key 3, in the variant embodiment

  shown in Figure 2, although starting from a semi-

  1, has the particularity that the crenellated part 5 intended to form the code, as in the previous case, to allow the opening of the lock, may comprise a cut in form dovetail in which is installed a small cover 8, so that it is not

  As can be seen in FIG. 3, the female part is constituted by a carcass formed by the part or by the parts 9 and 10 which constitute a kind of box inside which are placed, being screwed on the part which one could call the roof of the housing, that is to say on the part 10, and inside thereof, 2 plates which bear the reference 11, by means of the screws represented in this FIG. 3, being separated from each other to allow the installation of a magnet 12 in the form of

  elongated rectangular tray Immediately below

  below is located a block constituted by the plates 13 and 1 which also comprise orifices identical to those 12 -

  1 of the plates 11, for their attachment by means of the screws corres-

  lying between these plates 13 and 14 two plates 15 between which is formed a gallery whose access is obtained through the opening that can be seen in Figure 1, which is provided with the front portion of the housing and through which it must penetrate the elé which in this case will be rectangular, when the key is of flat version, whereas if one uses a key like that which is represented in Figures 5, 6 and 7, this orifice will be naturally round, and therefore the block formed by the plates 13, 14 and the plates 15, may constitute a single set with adequate perforation, which does not

  Below the plate 14 there are separations

  rings in the form of rings, which in combination with other separators located at the bottom of the lower portion 9 of the housing, receive a plate 16 which comprises a printed circuit with a support 17 which contains inside magnetic detectors which are connected to c @ circuit board,

  while the printed circuit is connected by means of

  In any of these figures, it can be seen that the assembly is contained in a carcass 41, from one side of which emerges the peg 26 which, from the constructive point of view, can be considered or can be described as a bolt having a radial appendage 27 near its trailing end, which is driven; at the opportune moment, by the piece 28, which comprises at this eff <a groove 29 in which is housed, as one can

  see Figures 10 and 11, Appendix 27.

  The groove 29 is formed at the end of the piece 28, and this piece is provided at its end opposite the groove of a hinge 30 which allows it to rotate:

  freely on the rod-shaped part 31 and also.

  on another link 32 which can both turn

  freely around the joint 30.

  : The link 31 is in turn articulated on the axis of rotation 33, relative to another part 35

  whose function will be described later.

  On the other hand the rod 32, articulated by its end 30 on the parts 28 and 31 is also articulated freely on the pivot 40 mounted on the structure of the carcass 41
