FR2868106A1 - Locking device for securing e.g. precious jewel in case, has electronic chip placed in strike, and electronic card sending alert signal for indicating that lock is not closed, if card does not read chip - Google Patents

Abstract

The device has a bolt (2) moving inside a body (1). A strike (3) has a hole (4) that permits to lock an opening when the strike is pushed to the bottom of the hole and permits to unlock the opening when the strike is pulled out of the hole. An electronic chip (8) is placed in the strike, and an electronic card sends an alert signal for indicating that a lock is not closed, if the card does not read the chip.

TITLE OF THE INVENTION.

  Locking certified by reading an electronic chip (8) placed in the latch of a latch (3) through the contact of the bolt (2).

  The present invention relates to a device applicable to locks and allowing reading through the contact of the bolt (2) of an electronic chip (8) placed in the striker (3) to absolutely certify that 1. the bolt (2 ) is locked inside the hole of the keeper (4) provided for this purpose, 2. the striker (3) is the one which is authorized to lock the bolt (2).

  The device allows misguidance to transmit. information when a latch is closed mat indicating the address of the closed mat latch. it also triggers an alarm if a lock has been opened without authorization or opened too long.

  Locking controls are traditionally done mechanically or electronically for your electric or electromagnetic locks.

  In some cases, there are contacts of openings (very often by magnetic contact, bulb reed or mechanical button) which make it possible to send a signal when the lock is not closed.

  These contacts can be easily deceived by malice: presence of a magnet for your magnetic contacts or false seeds for the mechanical contacts.

  shots can also be deceived by negligence, the door being closed but not locked, or by default of operation of the locks (especially in the case of reed bulb closure detection).

  The present invention overcomes all these. defaults. It relates to a device capable of absolutely certifying interlocks by an electric circuit that reads an electronic chip (8) placed in the striker (3) via the bolt (2) - an electronic chip (8) ( preferably Dallas e) is placed in the striker (3) - the electronic chip (8) placed in the striker (3) is read via a bolt (2) (preferably mild steel) which comes to do contact with the striker (3), the electrical contact is only made when the striker is in contact with the bolt which means that the door (or drawer) is effectively closed and the bolt is released in the blocking position.

  - Your reading of your chip (8) can certify that the closure is done by the only strike (3) enabled without any other means of substitution.

  The FIG. 1 discloses all 3 parts of a latch the body of the latch (1); bolt (2) movable inside the lock body (1); your keeper (2) which blocks the bolt (3) in a hole (4) made for this purpose.

  FIG. 2 describes the 3 parts of the lock with the details of the invention.

  FIG. 3 is an enlargement of FIG. 2 on your part of the bolt (2) and insulators (17).

  Schematically, the locks comprise 3 parts (FIG 1) the body of the lock (1); the bolt (2) which is a moving part inside the lock body (1); the keeper (3) comprises a hole (4) which makes it possible to block the opening when the bolt is pushed to the bottom of the hole and which makes it possible to unlock the opening when the bolt is pulled off the hole.

  The device is installed in the 3 parts of the latch (striker, latch and bolt body) to be managed by an electronic card that reads an electronic chip (preferably Dallas) (FIG 2) The striker (3) - an electrical insulator (5) around the hole of the striker (4) with a lead element (6) (preferably brass) in the bottom of the strike hole (4) - an identifying electronic chip (8) of the company Dallas ( preferably) placed in the keeper (3) in a cavity provided for this purpose: (9). the chip has 2 tabs i a tab isolated from the mass of the striker (7) and connected to the inside of your chip conductive element (6); the other leg (10) connected to the mass of the striker (12), a magnet (11) makes it possible to make a safe mass contact between the striker (3) and the body of the lock (1); he avoids a game in the door; it allows to position the bolt (2) in the middle of the hole of your striker (4).

  The bolt (2) - bolt (2) mild steel (preferably) is conductive, It is isolated from the mass of the body of the lock (1) by an insulator (17) preferably plastic.

  - The spring (18) which pushes the bolt (2) in the locking position is also isolated from the body of the lock (1). He is in contact with driver. bolt (2) and stumble on an insulation (17).

  - An electrical fit (14) welded to the end of the spring (18) can lead the electrical contact current to an electronic card (15).

  - A winding (16) surrounding the plastic insulator (17) allows, when powered by an electric current, the retraction of the bolt (2) in the body of the lock (1).

  The electronic chip (8) (Dallas preferably) placed in the striker (3) each electrOnique whore (8) has a unique identifying number, taken in general On a combination of 24 hexadecimal characters which is known from the electronic card tors de 'installation.

  it} 15 30 A 3 - your electronic chip (8) is integral with the striker.

  The electronic card (151: - the combinations of all the electronic devices are stored on an electronic card (15) - the card ilettroniqtte (15) constantly reads (preferably every hundredths of a second) all the electronic chips (8) If it does not read one of the stored combinations, it sends a signal (preferably a dry contact) to indicate that one of the locks is not closed and gives the signal. (or the number (s) -identifier (s) it does not receive, - With the help of a microprocessor, it is possible to manage by a table the names of the locks in clear (according to names given by your users) next to the ID numbers.

  The device of the bolt is specified FIG. 3 in enlargement of FIG. 2 for the parts of the bolt (2) i of the plastic insulator (17), the spring (18), the ileWique current conductor (14) welded to the spring (18) and the weld point (19).

  The device can be implemented whenever it is necessary to check the closure of a mechanical latch itself, or when one wants to make sure that one. removable set is in posftton blocked.

  The electrical circuit path for locking Menti ication is as follows: -electronic board-output (15), then spring-bolt-Xia), then bolt- (2), then strike bottom (4), then electronic chip Dallas (of preference) (8), then body of the ghe (3), then magnet (11) then body of the verrmi (I), eds back care é.1et-tenique (15). The electrical insulators (ii) of the bolt (2) and the electrical insulators (5) of the. strike (3) are arranged in such a way na can not establish (by accident or malice) de-contact. electric between the bolt (2) and the bottom of the striker (6) without physical contact without having to: neken the bolt (2) _ So that a forced opening will be urs detected and so that a contact (accidental) between the bolt (2) and the mass (12) no longer allows the identification of the ptioe (al and ain- triggers the warning signal To perfect security, it is expected to add an ion either By mechanical contact, either by means of a mechanical release or by any other method, indicating that the bolt (2) is in the extended position in the hole provided for in the hole (4), the head 30 is transmitted to the electronic card. (15).

  The industrial applications are therefore all the locking systems in all areas, from the jeweler's drawer to the hangar gate, from the sliding glass to the door actuated by cylinders. The areas concerned are those of your property security and the rsonnes 10 20 ... 25 y - esi.ci; es the position of the vdr ç-rf is-nt ,, i? e:. In the map, nff is possible 7 e T '' aerer, = in the case of normal opening, an opening delay av will start from one day to the next! to send- an alarm ,. in case of security breach: As a free for security property, t reported identified !! It is not necessarily indicated that the number is a number. the revenue received.

  As an example, for the need a dialogue entered closed? - Answer: Yes door closed.
