FR2707324A1 - High-protection motorised lock - Google Patents

Abstract

Method making it possible to achieve a high degree of security both in the closing and in the opening of a multi-bolt lock of a door of a dwelling, involving the automatic and systematic movement of a plurality of motorised parallelepipedic bolts 10 during each closing of the door, another independent bolt 3 ensuring manually the mechanical additional locking of the assembly and the cut-off of supply to the motorisation of the other bolts. If the second manual means has been used, each opening necessitates the preliminary use of a material means: the key C making it possible to release the independent bolt and restore supply to the motorisation of the other bolts 10, and the subsequent use of an immaterial means, such as a numerical or alphanumerical code, validated on a keypad 15 generating an electrical control pulse loading the motorisation of the other bolts in the opening direction.

Description

1 2707324

  The present invention relates to residential door locks allowing high security to be obtained both at the closing and at the opening of a multipene lock (at least three) and with two connecting rods in the case of at least minus five bolts and a key driving at least one bolt. In a previous application No 88 03400 filed in France on 16.03 1988 and in a corresponding EPO application No 0333588 filed on 16.3.1989 by the same inventor, a process and methods have been described.

  means to obtain the result indicated above.

This process consists of:

  - when opening from the outside, always to be combined simultaneously-

  instantaneously an intangible medium consisting of a code

  delivering a timed electrical pulse controlling a

  seems electro-mechanical unlocking a set of rods and bolts and a material means constituted by a key allowing the mechanical translation of said rods and bolts and its bolt half-turn, - on closing, and to compensate for the low resistance of the bolt half turn, manual rotation of the key causing displacement

  rods and bolts and automatic locking of them

  ci by the action of the electro-mechanical assembly which, under the action

  a spring and its beveled bolt prohibits any new movement

  cement. The present application, like the previous invention, provides high security both at opening and at closing, but by

  a different process and means including in particular the motor-

  sation of the auxiliary bolts allowing automatic closing and

  systematic of these at each door movement.

  The process according to the present invention essentially consists:

  when closing from outside, with automatic movement-

  ment of the two or four auxiliary bolts in their strike housing, with the exception of the central boot bolt, under the action of one or more electric motor-reducer groups, the only closing action by the user then being the rotation of the

  key driving the third or fifth closing pin associated

  ciant in its displacement by the contact of a microswitch the discontinuity of an electric circuit of supply of one or groups motor-reduction, With the opening of the outside: - in the rotation of the key, unlocking the third or fifth pin and restoring in its movement the continuity of the supply circuit of the motor-reducer group (s),

  - by dialing at least one numeric or alpha code-

  numeric on an external keyboard, followed by its validation, managed by a microprocessor with its computer logic, delivering an electric pulse, supplying the motor-reducer group (s) in the opening direction; if the door has not been moved by

  the user following this opening and for a predefined time

  finished, the closing will be restored automatically under the action of the electric pulse of closing preprogrammed, With the closing of the interior: - in the automaticity of the translation of the two or four bolts

  auxiliaries in their strike housing and the third or fifth

  quième pDne by the key if the user decides, When opening the interior: - in the simultaneous use of two material means: the key, if the user has previously rotated it, it is to say to

  closing, and a push button as well as a remote

  control delivering an electrical pulse supplying the motor-reducer group (s) in the opening direction; if the door has not been moved by the user following this opening and

  during a predetermined time, the closure will automatically re-establish

  only under the action of the electric closing impulse

  programmed, - the opening of the interior can also be obtained by the simultaneous use of two means, a material: the key, if

  the user has previously rotated it, and immature means

3 2707324

  physical: a numeric or alpha-numeric code, followed by its validation

  tion, composed on an internal keyboard, the said code being managed the microprocessor and its computer logic, generating an electrical pulse supplying the motor-reducer group (s) 5 in the direction of opening.

  The means for implementing the process defined above

  include in combination: a main trunk lock

  cluting a deadbolt, a bolt or not movable with roller, its barrel and its key, separated from the rods and auxiliary bolts but controlling, via a microswitch, the opening or closing of a circuit electric allowing or not feeding one or more motor-reducer groups moving the auxiliary flaps; two motorized,

  four or more, and an integrated numeric or alpha-numeric keyboard

  in the exterior handle of the door, - an electro-

  management picnic including its microprocessor generating a pulse

  electrical power supplying one or more motor-reducer groups moving the auxiliary pins in one direction or the other

  for opening or closing the lock.

  The auxiliary pans can be two or four in number; two at the top, two at the bottom, arranged on each side of the main boot, and controlled simultaneously by a group of two motem-s

  reducers one way or the other.

  An embodiment of a lock will be described below, including

  four auxiliary bolts and two rods, as well as its function-

  With reference to the appended drawing, in which: FIG. 1 represents a general exploded view of the lock, and FIG. 2 represents the constituent elements of the

lock seen from the inside.

  In these Figures, the same elements have the same references.

  In FIG. 1, the reference O designates the support box, the references 3,2 and 4 respectively designate the deadbolt,

4 2707324

  its barrel and a movable roller blade from the main boot 1.

  Also visible in this figure: the auxiliary pins 10 and 10 ′, a keeper G, the closing position detector 13, the

  external keyboard 15 and the external handle 16, the power cable

  and link 17 and the hood CA, the power supply housing including the backup battery B, the power cable

  220 Volts D sector, the cord and its ex-power plug

  E. In FIG. 2, the following references designate respectively: 0 the support box, 1 the main trunk including the barrel 2.1e deadbolt 3, the mobile roller pin 4, 5 the output pin of the

  trunk 1, 6 the micro power cut-off switch

  8, 7 and 7 ′ the power supply reversing relay circuits of the 8,8 ′, -11 and 11 ′ motor-reducers, the end microswitches

  of race controlling closure, 12 and 12 'the micro-interrup-

  limit switches controlling the opening, -13 the electronic closing position detector, -14 the electronic circuit

  and 17 the power and connection cable.

  The operation of the lock is as follows: The closing of the lock from the outside is obtained automatically at the moment when the closing position detector 13 is opposite its reflective patch located on the keeper G. At this instant, the detector 13 requests the electronic circuit of

  management 14, which delivers an electrical pulse supplying the mo-

  8.8 reducers for movement in the closing direction

  rods 9 and 9 'and auxiliary panels 10 and 10'.

  If the user wishes to obtain high security, he can by rotation

  of key C in the main boot 1, put it in the over-

  mechanical locking of the entire lock by movement of the fixed frame 3 in the closed position and jointly the

  power supply cut off to the 8 and 8 'gearmotor motors by the displacement

  cementation of the lower or upper finger of the trunk requesting the

  power cut-off microswitch 6.

  Following this last maneuver, the only composition of the

2707324

  code (immaterial element) on the external keyboard does not generate an opening movement of the motor reducers 8,8 ', the key material element will be essential to restore the circuit

  of power to the gear motors and unlock mechanical

  the lock, and at this time only a validated code will allow

the opening of the auxiliary panes.

  The door is closed from the inside automatically and in the same way as from the outside, and if the user wishes to

  high security, it can by rotation of the key in the internal barrel

  laugh 2 get the same result as the one obtained from outside

by the same maneuver.

  The lock is opened from the inside, if the user has previously rotated the key to the position

  closing, first by turning the key in the direction of the

  and then by pressing a push button 18

  edge of the hood CA through the passage 18 ′. This pressure exerted on the push-button acts on the electronic management circuit 14 which delivers an electric pulse supplying the motor-reducers 8,8 ′ for movement in the direction of opening trindles

  9 and 9 'and auxiliary bolts 10 and 10'.

  The push button could be replaced by a numeric keyboard or

  alpha-numeric arranged on the face of the CA cover or offset.

  The digital keyboard could also be replaced by a reader

  proximity badge for indoor reading only; parallel-

  With these two means, a remote control device could be

  implanted, which would allow remote opening of auxiliary p & ns

  liaries. As indicated above, the lock which is the subject of the invention can be produced in forms different from that which has just been described and which constitute variants thereof; this is how the number of the auxiliary panels could be two, four or more, distributed in equal number on either side of the central boot, and the geared motor reducers reduced or increased according to

cases.

  The trunk key 1 could control, in addition to the central trunk,

6 2707324

  two bolts at the top or bottom.

  A single motor-reduction unit could control two pones from the top or from the bottom. In this case, it saves a motor-reduction unit, but the lock is unbalanced in its height and at the closing points. Any lock comprising a half turn, with or without an electric strike, does not provide high mechanical protection, only a

  or several parallelipiped pins can provide this security

  rity provided that they are systematically engaged as part of each door movement. Only the engine allows it,

  and the rotation of the key will be the complementary and essential element

  sand to obtain mechanical and electrical double locking.

  The code alone is the necessary but insufficient element to obtain

  nit opening. It is the same for the key: In conclusion: the high protection at the opening will always be the association of

  two means: one material; the key, the other intangible code.

  High closing protection mechanically requires several

  parallelipiped pones systematically engaged in the lumi-

  strike release and manual action of a mechanical lockout

  by an independent bolt associating in its displacement the disconti-

  naked electrical supply circuit.
