Description

"Automatic Access Control Lock with Weapon Detection" This

  The invention relates to the field of access control, particularly bank offices, and

  object an airlock allowing to pass

  people without a weapon and to control others. This in order to limit the armed attacks during the opening hours of the customer offices. The system can also be applied to access control for any type of building such as Embassade, factory, offices, halls

computer, etc.

  Weapon control devices currently used at the entrance of some buildings, for example airports and embassies, require the permanent presence of a supervisor. This checks the passage of visitors through the weapon detector portico, and searches through

  a booth each of those who triggered the detector.

  These devices also require at least one armed guard

  to prevent a possible forcible passage of an intruder.

  The present invention aims to perform an automatic control limiting the intervention of personnel

  expensive and limiting the space occupied on the ground.

  It essentially comprises an airlock with walls (19) resistant to bullets, an outer door (1) opening inside a weapon detector (3) and sweeping the volume

useful detection of it.

  By closing, the door (1) sweeps on the other hand all the

  dead volume located before the useful detection volume.

  This dead volume is also limited by the floor, the ceiling, the walls (21) and (23) and the door (1) in position

closed.

  The visitor with his luggage must pass through the useful volume to allow the door 1 to close again

behind him.

  There is no space between the door (1) and the floor, or between the door (1) and the ceiling, or between the door (1) and the wall (21) that would allow a visitor to return an object in the airlock and close the door (1) behind him without the object and the visitor crossing the useful volume of the

weapon detector.

  A vertical bar (25) fixed on the wall (23) obstructs the passage between the hinges to prevent the introduction of an object into the dead volume between the

  wall 23 and the door (1) in the open position.

  A first presence detector (5) is placed near the door (1). A second presence detector (6) is

placed near the door (2).

  The use of at least two presence detectors makes it possible to automatically know whether the person who is in the airlock wants to enter or exit, solely by his position relative to the doors. This avoids the use of push button,

  simplifies access and speeds visitor passage.

  An inner door (2) with electric lock (8) A light (30) "open", a light (32) "wait" A light (16) "open", a light (18) "wait" An electronic management (24) A control console (26)

  The following description and operation is

  relate to a preferred embodiment given as a

non-limiting example.

  The weapon detector is a motion detector

  metallic mass by eddy current.

  The two presence detectors (5) and (6) are contact mats. The door frames (1) and (2) are made of fiberglass-reinforced synthetic resin with a horizontal reinforcing beam at mid-height. To ensure good rigidity despite the weight of the glazing, the entire frame is

  die cast hot one piece.

  The thickness of the resin and the fiber plies of

  glass is superior & 3 cm to stop the balls.

  Each door is equipped with laminated glass panes

  balls or windows made of polycarbonate.

  To avoid the metal parts on the doors, the 2 door closers (13) and (14) are embedded in the floor and the electric locks (7) and (8) are recessed

in the sleeping frame.

  In the rest position, the airlock is empty, the 2 doors are closed, the door (2) is locked by the electric lock (8) Case nl: A visitor without a weapon or important metal object, coming from from the outside pushes freely the door (1), enters the lock and advances in the area of the presence detector (6).

  The door (1) closes behind it via

  door closer (13) embedded in the floor.

  The lock (7) locks the door (1).

  The management electronics (24) verifies that the visitor is in the area of the presence detector (6), that there is no one in the area of the presence detector (5), that the door (1) is closed by closing the contact (11), that the lock (7) is locked by the contact (9) position

  of bolt, and that the weapon detector (3) has detected nothing.

  After these checks, the management electronics control the opening of the lock (8) which releases the door (2). A light (30) "open" indicates to the visitor

entering.

  The visitor pushes the door (2) which closes behind him.

  The system returns to the initial Pepos state.

  The visitor performed a simple and natural maneuver in

  successively pushing the door (1) and the door (2).

  He did not need to manipulate push button.

  There was no intervention by the surveillance staff.

  1 Case n2: A visitor with a large metallic object

  freely the door (1) and enters the airlock.

  When it reaches the useful area of the weapon detector, it holds the door lock (2) and triggers a buzzer in the control panel (26) to

alert the supervising staff.

  The supervisor can interact with the visitor through

  an intercom with a loudspeaker (20) and a

  microphone (22) placed in the airlock.

  If the visitor is perfectly known, the supervisor can release the door (2) by action on an opening button (28) located on the control panel (26) Otherwise the supervisor refuses access and asks the unknown visitor to come out of the airlock and placing his object in a

  deposit locker (27) located outside.

  In a fully automatic variant, in the event of metal object detection or mishandling of the visitor, the control electronics automatically sends instructions by a speech synthesis generator and the loudspeaker (20). This avoids any intervention of the

supervisory staff.

Case 3:

-------

  A visitor inside wants to go out; for that he

press the push button (4).

  The management electronics (24) verifies that there is no one in the airlock, that the door (1) is closed; she

  lock the door (1) by the lock (7).

  Then she unlocks the door (2) and commands

  lighting an "open" light (18).

  The visitor opens the door (2), advances in the area of the presence detector (5), which automatically controls the locking of the door (2) and then unlocking the door.

  the door (1) and the lighting of an indicator (15) "open".

  The visitor opens the door (1) and leaves.

  The door (1) is closed by the door closer (13) and the

  system returns to the initial idle state.
