Description

Miniaturized security lock comprising a bolt and use for security purposes

Technical field of the invention

The present invention relates to the field of security furniture such as safes, security cabinets and containers and in particular proposes a miniaturized security lock comprising a lock locked and unlocked by an electromagnet mechanism or a micromotor system , integrating an electronic system with microprocessor control locking and unlocking of the bolt of the lock for the purpose of security.

To protect property, it is known to use safes or security cabinets generally comprising an armored door equipped with a security lock connected on the front face of the cabinet to a keyboard allowing the introduction of a code. The shielding, corresponding to a set of equipment, for example, metal plates, makes it difficult to break the door and protects the cabinet or the safe from any break-in, in particular by preventing any individual from accessing the locking system. and unlocking the door, the locking and unlocking system being located on the rear face of the door. In this way, many sites, such as banking sites, use these types of protection, safes or security cabinets or even containers, to protect their goods or documents.

But these types of property protection are the target of attacks carried out using perforating tools or cutting tools by heat or fusion or even cooling gases. As soon as an attack is detected, an alarm signal is triggered.

Currently, this detection and then this alert are ensured by bulky equipment independent of the locking and unlocking system, which requires the drilling and then tapping of fixing holes in the door shielding and a multiplication of electrical connections in the cabinets of the door. security, inducing a weakening of the mechanical resistance and consequent costs resulting from the intervention, additional fixing locations to be reserved

Document WO 2004/070143 proposes a lock cylinder provided with a protective cover and equipped with an actuator to activate the unlocking of the protective cover.

The electronic circuit receives detection signals from various devices: rod displacement detector, vibration detector in the vicinity of the box housing the circuit, temperature detector. These various elements are housed in a box parallel to the axis of the lock requiring separate fixing. The barrel requires an electronic circuit with centralized connections to a
signal receiver encoded to authorize the movement of the protective cover. Furthermore, detection can only be done in the absence of electronic authorization to move the protective cover.

It is also known, from US 5,311,168, an alarm system embedded in a door locking mechanism. But this alarm system has no temperature variation detectors and only works when the “alarm” mode is activated. In addition, document GB 2 286 423 proposes a security system triggering, using detectors, alarms in the event of unauthorized attacks. This system also lacks temperature sensors. In addition, the size is relatively large since the detectors are placed in the door.

Miniaturized and mechanically secured locks of the rotary lock type controlled by an electromagnet are also known. Such a system is taught by application US2015115629.

These locks are therefore not protected against various types of attacks and the repetition of attacks.

The present invention aims to overcome one or more
disadvantages of the prior art and proposes a miniaturized security lock comprising a lock incorporating an electronic microprocessor system for locking and unlocking the lock and for detecting attempts to break into a piece of security furniture such as safes or safety cabinets or even containers with a low cost implementation and a minimal footprint.

The miniaturized security lock is made to be installed on safes and security containers, strong doors, but it can also be used on building doors or openings of all security levels, walls or any other product requiring the detection of vibration or temperature rise, it can also be used to trigger smoke systems, smudges or any other system which aims to render unusable the goods to be protected.

To achieve this object, the miniaturized security lock has a lock for locking an opening, said lock comprising a bolt, said bolt being able to be moved between a locking position in which it blocks the opening of the opening, and a position unlocking in which it does not block the opening of the opening, the lock incorporating an electronic microprocessor system for controlling a solenoid or a micromotor system for moving said bolt of the lock of the lock and for a purpose security incorporating a locking and unlocking system of the lock comprising a miniaturized detector of shocks or vibrations transmitted to the lock, as well as a miniaturized detector of temperature variation, the system being characterized in that it allows the triggering of the locking or unlocking the movement of the bolt, in response to values measured by at least one of said detectors, the lock further comprising a microprocessor or microcontroller comprising, on an associated or integrated circuit, means for establishing and storing different thresholds of detection of a vibration, or a shock.

According to another feature, the miniaturized security lock comprises means for establishing and storing a temperature rise threshold, and preferably a code table and a table of operating time ranges of the system of locking and unlocking.

According to another particularity, the lock comprises means for connecting a first contact for detecting the movement of the bolt and a second contact for detecting the opening of the leaf connected to a microcontroller and a ground to inhibit the detection of attempts break-in and/or delay reactivation of shock and temperature rise detection.

According to another particularity, the lock comprises a push button connected to the processor itself connected to a buzzer to facilitate configuration and to verify it by signaling by a sound, the entry into programming, after each impulse on the button defining a threshold different sensitivity corresponding to another sound modulation.

According to another particularity, the lock has LED visualization (for example, red and green) allowing the installer and the maintainer to check the correct operation and the level of triggering sensitivity.

According to another feature, the lock comprises means for being connected to an autonomous neutralization system which comprises means for spraying at least one destruction liquid with or without the release of non-toxic fumes on documents or valuables located at the interior of the security cabinet.

According to another feature, the lock is remotely controlled by a remote alarm center, in order to manage the lock and its functions remotely.

According to another feature, the miniaturized shock or vibration detector transmitted to the lock, the miniaturized temperature variation detector, and/or the lock and door position detection contacts are integrated and remote in an independent miniaturized box connected to said lock or directly to an alarm system, for example the remote alarm centre.

The invention will be better understood and other aims, characteristics, details and advantages thereof will appear more clearly during the explanatory description which will follow, made with reference to the appended figures given by way of non-limiting examples in which:

shows an interior view of the components of the security lock in which several miniaturized detection systems are integrated;

shows an exterior view of the lock case with the lock consisting of a bolt;

represents a detailed view of the electronic card and the detection devices;

The present invention will now be described with reference to Figures 1 to 4.

The principle of the invention is to provide a miniaturized security lock as illustrated by way of example and in a non-limiting manner in FIG. 1, comprising a lock for locking an opening, said lock comprising a bolt, said bolt being able to be moved between a locking position in which it blocks the opening of the leaf, and an unlocking position in which it does not block the opening of the leaf, the lock integrating an electronic control microprocessor system a solenoid or a micromotor system for moving said bolt of the lock of the lock and for security purposes integrating a locking and unlocking system of the lock comprising a miniaturized detector of shocks or vibrations transmitted to the lock, as well a miniaturized temperature variation detector, the system being characterized in that it allows triggering of the locking or unlocking of the movement of the bolt, in response to values measured by at least one of said detectors, the lock further comprising a microprocessor or microcontroller comprising, on an associated or integrated circuit, means for establishing and storing different vibration or shock detection thresholds. The system also comprises a miniaturized temperature variation detector (12), connected to a microprocessor (10) making it possible to supply a solenoid (20) or a micromotor system for triggering the unlocking of a bolt (21). The microprocessor (10) may comprise, on its printed circuit, a first communication interface with either a central alarm system or an autonomous neutralization system located within the enclosure of the part to be secured, a second communication interface (not shown) with a keyboard for entering a code (21) allows the activation of the unlocking of the bolt and by rotation or movement of a handle, integral with the axis of rotation (211) of the bolt in the case of a rotation of the handle, and positioned on the outer face of the opening on which the lock is fixed allow the movement, here the rotation, of the bolt in the unlocking position to authorize the opening of the opening. The automatic closing of the bolt being ensured by a spring (22), bringing the bolt (21) back into the locking position as soon as the handle is released.

It is understood that by "lock" or means a rotary lock, or another type of lock which comprises at least one bolt, and when the lock is actuated, this causes the movement of the bolt, causing the locking and unlocking of an opening , for example a door of a security cabinet.

“Opening” means a part or a component of a device which opens, and the opening of which can be blocked and locked by a lock.

In some embodiments, the lock is a twist lock. In other embodiments, the bolt is moved by translation for example.

In one embodiment of the invention, as illustrated by way of example and without limitation in FIG. 3, two vibration detectors (11a, 11b) each consisting of an accelerometer are independently connected to the microprocessor .

This system integrates all these functions and its miniaturization allows its integration into any type of container.

The seismic detector composed of different accelerometers controlled by the microcontroller is configurable according to the environment in which it is installed, the use of several accelerometers makes it possible to offer the possibility of detecting a large range of vibration and movement on the 3 dimensions, moreover, the precision of the components and the software integrated into the lock make it possible to find the same data and results from one product to another (which is not the case with other detection systems) , with our system several products installed in the same configuration give the same result.

Its configuration does not require any external software or external device but is done directly in the box.

The different sensitivities offer a large detection amplitude and allow its use on many different media.

The microprocessor powers two diodes (D1, D2) to indicate when they are illuminated, respectively the detection of a level 1 shock or a level 2 shock.

A LED visualization (for example, red and green) allows the installer and the maintainer to check the correct operation and the level of triggering sensitivity, he can check if in the environment in which he is located, the system does not is not likely to trigger on its own and if it triggers correctly during the tests carried out by the technician.

Similarly the adjustment of the lock is done by a small push button (27) connected to the processor (10) itself connected to a buzzer (28) which facilitates the configuration and to check it by signaling by a sound, the entry into programming {for example after each power cut, or after each first press, for example, of the push button (27)}. After each pulse on the button, the microprocessor stores either in its memory 103 or in that of the accelerometer, if the latter is equipped with a memory, the number of pulses and, for example, a stored table defined for each number of pulse a sound modulation thus indicating the threshold chosen from among the various thresholds, this number of pulses corresponding to a chosen sensitivity threshold. Then the maintainer can, for example, request the reproduction of the sequence, by pressing the push button (27) longer than those of programming, which triggers the reproduction of the sound modulation to indicate in an audible way the level of chosen sensitivity, for example, by modulation of the sound according to the number of stored pulses. For example, it is the number of rings that gives the level of sensitivity corresponding to the number of pulses executed on the button.

In one embodiment, the microcontroller includes an element that records the number of pulses corresponding to a chosen sensitivity threshold and audibly indicates the chosen sensitivity level by a specific sequence of sounds.

Most detectors have random trigger levels, they are not identical from one device to another and can vary with humidity and temperature, our system guarantees reproducibility from one device to another.

The analysis of the signals is not fine enough to sometimes differentiate an attack from the hectic environment, the system of the invention, thanks to its management of the different levels of sensitivity, is not disturbed by the natural environment. where it is and can be easily modified by the installer or the maintenance technician in the event of too frequent triggering due to the environment (vibrations due to the presence of a Metro or a nearby train track, for example a nearby SNCF).

The thermal detector is pre-programmed to a level guaranteeing triggering in the event of an attack but without the risk of untimely triggering linked to the environment in which it is located, if necessary, the triggering temperature can be modified at production by modification in the software of the microcontroller.

The system remains functional even after a thermal detection unlike some systems on the market which use a thermal fuse which can only be triggered once.

In certain embodiments, means for storing (103) the thresholds for detecting a vibration, a shock or a rise in temperature, and/or a code table and a table of time ranges of operation of the locking and unlocking system (2) of the lock. Preferably, the lock further comprises a power supply means, for example a micro-battery, to continue to supply the internal clock, for example in the event of failure of external power supply means.

This miniaturized detection system (1) is integrated or associated with the electronic locking and unlocking microprocessor system (2) of the lock, also called lock, of an opening of a piece of security furniture such as safes or cabinets security or armored containers or doors. The miniaturized detection system (1) is, more particularly, suitable for locking and unlocking systems (2) of the electronic type and makes it possible to increase security with simple implementation at low cost and minimal bulk. Security cabinets generally comprise an armored door, on the front face of which is a keyboard allowing the introduction of a code, and the locking and unlocking system of the lock (2) is located on the back of the face comprising the keyboard introduction of the code, that is to say inside said security cabinets.

A closed bolt signaling contact (SW1) is connected on the one hand to the processor and on the other hand to a second signaling contact (SW2) itself connected to ground. When these two contacts (SW1) and (SW2) are both closed, the microprocessor or microcontroller being connected by these two contacts to ground is powered and triggers the alarm in the event of vibration or temperature detection. When the bolt is unlocked, for example following the entry of the security code of the lock on an external keypad, and the contacts are closed signaling the closing of the opening, the rotation of the bolt is authorized by unlocking and the contact SW1 is open as soon as the bolt rotation handle is activated. In this case (opening authorised) the microprocessor will no longer trigger an alarm, even if the detectors detect a vibration or a rise in temperature. When closing the opening, the SW2 contact is formed first, then the SW1 contact thus restores the activation of the microcontroller. The timed reset or reset of the microcontroller is performed. Thanks to the management of the contact with delayed reset by the system, there is no longer any triggering of the system during the door closing sequence.

Many older systems are often disabled after a few months of service and nuisance tripping or set to never trip.

The opening being closed, in the event of detection, the microcontroller (10) sends on its output (105) a signal to a relay R1 whose contacts are connected to an alarm which will be triggered upon detection by the microcontroller of an attempted break-in by shock or vibration or by temperature variation. In the variant embodiment shown, output (105) supplies relay R1 at rest and de-supplies relay R1 if a shock or a thermal change is detected, thus opening the relay contacts.

The microcontroller 10 supplies via its output 106 a relay R2 whose contacts remain closed in the absence of burglary detection and stops supplying R2 so that its contacts open if the door or the bolt are open, this is to say when sw1 or sw2 are open.

This advantageously provides additional information for the alarm management system. Indeed, it is possible to prevent the activation of the alarm if the contacts are not closed, in order to force the user to close his trunk properly. Another possibility, independent of the first and cumulative, is to send an alarm if the contacts remain open too long.

A reinforcement stop (26, fig. 1) is positioned, in the event of forcing during a break-in attempt, in a housing formed in the bolt (21) to help block the bolt.

The miniaturized and secure locking and unlocking lock (2) is fixed by means of screws to the back of the face of the door of the security cabinet on which the code entry keypad or the bolt rotation control handle is placed. .

In addition, the device comprising the electronic control system of a lock can be remote from the latter, is of substantially rectangular shape and can have a length (L) of 40 to 60 millimeters, preferably substantially equal to 50 millimeters and a width (I) of 35 to 55 millimeters, substantially equal to 45 millimeters, thus presenting a minimal bulk, ie almost 4 times less surface area than on the older product generations.

Miniaturization considerably reduces the size and allows installation in many cases where old technologies could not be integrated.

This is why we have sought maximum miniaturization through new technologies.

The electronic locking and unlocking microprocessor lock (2) of the security cabinet is powered by power supply means,
corresponding to a battery or a block of batteries, which are arranged either in the enclosure of the security cabinet or in the code introduction box. The miniaturized shock or variation detector (11) makes it possible to detect, according to the sensitivity settings, weak vibrations or weak shocks, produced by tools
even light perforators, on the element to be secured.

The miniaturized temperature variation detector (12) makes it possible to detect a temperature variation, in particular, a heating produced by an attack carried out using cutting tools by heat or by fusion, or else a cooling produced by an attack carried out by
cooling gases.

A second use of the invention will now be described.

The microprocessor (10) sends on its output (105) a signal to a relay R1 whose DOCT connection terminals are connected to an autonomous neutralization system to be triggered when an attack is detected by at least one miniaturized detector (11 , 12), that is to say a shock or a vibration or a variation in temperature located beyond a threshold. The thresholds are stored in the storage means (103) of the microprocessor (10). The autonomous neutralization system projects at least one destructive liquid, for example ink, onto documents or valuables located inside the security cabinet and thus destroys the documents to render them unusable. This autonomous neutralization system is located inside the security cabinet.

One of the advantages of the invention is the constitution of a security system for safes or security containers composed of several control elements:

- the position of the door and the locks,

-the detection of break-in attempts by blowtorch, thermal lance, drill, grinder and many other types of mechanical or electro-mechanical tools.

The integration of all the seismic, thermal, lock and door position contact functions guarantees maximum safety as well as very high reliability, eliminating most nuisance tripping.

The system is equipped with 2 independent output relays for triggering an alarm following seismic or temperature detection and 2 independent output relays to indicate the lock and door position.

In certain non-limiting embodiments, the miniaturized shock or vibration detector transmitted to the lock, as well as the miniaturized temperature variation detector are integrated and remote in a miniaturized box connected to said lock or directly to an alarm system , for example from the remote alarm centre. Said independent miniaturized box can also be connected to any other information operating system coming from the safe locked by the lock. Said box can also include the lock and door position detection contacts.

In some embodiments, the lock is remotely controlled by an alarm center. The lock is then suitable for direct operation by an alarm centre. An input is available to control the unlocking of the system, it makes it possible to manage, for example, the interlocks between the safes and the doors, as well as to use the opening hours of the alarm system, and the time delay.

Thanks to the electronic system with integrated regulator, great flexibility in the choice of power supply is allowed for the lock, but above all the ability to remain powered, for unlocking the door, for 60 minutes without heating up and risking damaging the internal mechanism. .

This has the advantage of being able to guarantee both a wide supply range, a long unlocking supply time and fully mechanical automatic closing that is not subject to an electrical command.

The possibility of leaving the lock powered for such a long time with this wide voltage range therefore makes the design of the systems controlling the opening and closing of the safe less restrictive and ensures security for the contents since it does not heat up.

In certain embodiments, the lock comprises a supply means for continuing to supply an internal clock in the event of failure of the external supply means.

In some embodiments, the lock includes a system for delaying the re-arming of alarm triggers in order to eliminate nuisance triggers.

In certain embodiments, the lock and the system comprising the detectors are remote, the system being remote in a box connected to the lock.
