Description

Subject of the invention

The present invention relates to a new intrusion detection device allowing detect a potential intruder or burglar who manifests the intention to enter a dwelling, house or apartment, office, store, etc.

State of the art

In the area of building security, the various known protective equipment, comprising ultrasonic, infrared, volumetric detectors, etc., are based on the detection of the presence of a person, when it enters space or surface of a monitored area. In the case of a house residential, it is imperative that the intruder enters the house, for example by forcing the door, so that the detection and alarm device works.

Furthermore, if we take the case of a apartment located in a building, the access corridor being generally common, the presence a traditional detector, placed outside, by example above the door would trigger the alarm constantly and unnecessarily every time a neighbor passes by. Besides, passing does not mean that there intends to break in.

On the other hand, when the house or the apartment is occupied by one or more people during the day, traditional alarms should be obviously disconnected, under penalty of constantly obtaining nuisance trips, caused by back and forth of said people.

Traditional alarms are therefore not effective only when the apartment is unoccupied or during at night, to protect certain selected areas, such as the ground floor for example, when the occupant is layer.

Finally studies have shown that the intruder potential, who wishes to enter a building, will have as a first reflex to check if the door is locked from the inside, which necessarily requires actuate the latch to release the movable lock. This particularity, to the detriment of the intruder, is not operated by state of the art detection systems technical.

Aims of the invention

The object of the present invention is to provide a solution that overcomes the disadvantages of the state of the technical.

In particular, the present invention has for goal of proposing an intrusion detection device responding to a new philosophy in protection of property and people, which is proactive and preventive rather than reactive.

The invention has the complementary aim of instantly detect the potential intruder, who is always outside the protected area, while showing intent to break into.

Main characteristic features of the invention

The present invention relates to a device wireless electronic security, for the protection of a building in whole or in part, preferably a house residential or apartment; intended to detect intends to enter the interior of said building manifested by a person, characterized in that it is provided with means for detecting an attempt opening a door or window from the outside by said person without damaging it.

Advantageously, said means include a detector comprising at least one magnetic switch and a magnetic trip device comprising a magnet and secured to a movable part of said door or window, an emerging detection signal when the magnet is brought against the switch due to the setting in motion of the movable part, which is generally a latch belonging to the door opening mechanism or window, or a window opening.

Preferably, the detector comprises fixing means, power supply means autonomous, electronic components, an alarm sound and a connector for cable connection of said device to an external device, such as an alarm additional remote sound, power supply auxiliary, an alarm center or a transmitter telephone.

The invention has the particular feature that it there is no mechanical connection between the detector and the the distance between the detector and the trigger being adjustable.

Advantageously, the detector is provided with a time delay device, allowing a user authorized to open and close said door or window, in a limited time interval without triggering the alarm.

Preferably, the detector comprises on its front panel an indicator signaling an attempt door or window opening from the outside.

Particularly advantageously, the detector is active even if the mechanism is dismantled opening of the door or window, in particular of the latch and its axis.

According to a particular embodiment preferred of the invention, the detector comprises a card microprocessor-controlled electronics connected to control buttons located on its front side, so that different functions can be selected by a operator.

Preferably, these functions are selected by the operator either by pressing a single button at least once for a variable duration, either by pressing at least two buttons simultaneously.

• il détecte l'intrus potentiel qui est toujours à l'extérieur et qui a seulement manifesté l'intention de s'introduire dans la maison ou de commettre une effraction. Ainsi, l'invention se distingue de la détection par contacteurs magnétiques placés sur portes ou fenêtres. En effet, ces contacteurs sont placés à l'intérieur et déclenchent l'alarme lorsqu'il y a effraction, par exemple lorsqu'on essaie de forcer ou briser un châssis de fenêtre ;
• l'effraction n'ayant pas encore été commise, l'habitant dispose d'un temps beaucoup plus long pour réagir, téléphoner à la police, appeler du secours, etc. ;
• le détecteur peut être branché 24h/24, même si l'habitation est constamment occupée ;
• le détecteur est entièrement autonome, facile à installer et ne nécessite pas de câblage ;
• le détecteur est d'un coût inférieur par rapport à celui d'un système d'alarme traditionnel ;
• le détecteur peut compléter un système d'alarme existant, auquel il peut être connecté ;
• en particulier, le détecteur peut être connecté à un transmetteur téléphonique ;
• grâce à sa conception particulière, l'autonomie du détecteur est très importante car il ne consomme de l'énergie que lorsqu'il y a tentative d'intrusion ;
• le détecteur est de conception monobloc, c'est à dire qu'il intègre toutes les fonctions dans le boítier y compris l'avertisseur sonore ;
• il n'y a aucune liaison mécanique entre le détecteur et le déclencheur, ce qui autorise la présence de jeu dans l'axe de la clenche et qui rend le dispositif totalement polyvalent pour répondre à d'autres applications ;
• pour répondre concrètement à d'autres applications, il suffit simplement d'adapter le déclencheur ; dans le cas d'un magasin, par exemple, et durant les heures d'ouverture, il peut être utilisé comme avertisseur d'entrée. Il peut également servir pour prévenir de l'ouverture d'un tiroir-caisse, d'une vitrine, d'un coffret, etc.

The detection device according to the invention also has the following advantages:

• it detects the potential intruder who is still outside and who has only indicated an intention to break into the house or commit a break-in. Thus, the invention differs from detection by magnetic contactors placed on doors or windows. Indeed, these contactors are placed inside and trigger the alarm when there is a break-in, for example when trying to force or break a window frame;
• as the break-in has not yet been committed, the inhabitant has a much longer time to react, telephone the police, call for help, etc. ;
• the detector can be connected 24 hours a day, even if the house is constantly occupied;
• the detector is fully autonomous, easy to install and does not require wiring;
• the detector is of lower cost compared to that of a traditional alarm system;
• the detector can complement an existing alarm system, to which it can be connected;
• in particular, the detector can be connected to a telephone transmitter;
• thanks to its particular design, the autonomy of the detector is very important because it consumes energy only when there is an intrusion attempt;
• the detector is of monobloc design, that is to say that it integrates all the functions in the case including the horn;
• there is no mechanical connection between the detector and the trigger, which allows the presence of play in the axis of the latch and which makes the device totally versatile for responding to other applications;
• to respond concretely to other applications, it is sufficient to adapt the trigger; in the case of a store, for example, and during opening hours, it can be used as an entry alarm. It can also be used to prevent the opening of a cash drawer, a showcase, a box, etc.

Description of several preferred embodiments of the invention

The device according to a first form preferred embodiment of the invention is described on Figures 1.a, 1.b and 1.c.

This device consists of a detector 1, which is a housing containing in particular components electronic, and a mechanized part called trigger 2, designed to be placed on any type of latch 10. The shape of the trigger can be adapted according to the type of particular application.

The detector 1 includes a buzzer 3 serving horn, self-adhesive plate 4, cavity 5 intended to receive an electric battery and a cavity 6 intended to receive an electronic circuit.

The self-adhesive plate 4 allows the fixing from the detector to the door. A slide cover 11 provides access to the battery positioned in the cavity 5. Thanks to the holes 12 provided in the housing, we can also fix the detector with screws.

Trigger includes permanent magnet 7, an adjustment screw 8 allowing the length of the magnetic trip arm depending on the position of the door and / or door type detector, lock or snaps.

The trigger 2 is fixed on the axis 18 of the latch 10 via a removable jumper 19 to screw means 9.

Detector 1 is provided with a switch 13 serving as a time delay, when the inhabitant leaves the House. Indeed, thanks to this function, when he leaves home or when he comes in, he has a deadline, by example of 10 seconds, to close the door. In the otherwise the alarm will sound directly.

The detector is powered up by a “On / Off” switch 15. The detector is also provided with a clock 14 enabling the duration of buzzer operation 3.

The detector is also provided with a connector 16, allowing the installation of a second buzzer, for example in the bedroom, or connect to an existing alarm center so that greatly increase its potential.

Finally, the detector is provided with two magnetic switches 17. Depending on the direction of rotation of latch 10, when magnet 7 will pass in front of one of the two magnetic switches 17, this one will close and initiate the detection and alarm process.

The device according to a second form preferred embodiment of the invention is described on Figures 3.a, 3.b and 3.c. The operating principle of device is substantially the same compared to the shape described above, with the exception of certain functions that have been automated using the electronic capabilities of the system.

The detector 1 therefore includes a buzzer 3 serving as a horn, a self-adhesive plate 4, a cavity 5 intended to receive an electric battery and a cavity 6 intended to receive the equipment electronic control of the detector. The cavity 6 is provided with its access cover 60.

The self-adhesive plate 4 allows the fixing from the detector to the door. A sliding cover 11, sliding in a groove 110, provides access to the battery positioned in the cavity 5. Thanks to the holes 12 provided in the housing, you can also fix the detector using screws.

The trigger includes a permanent magnet 7 intended to sensitize the magnetic switch 17, a adjusting screw 8 for adjusting the arm length magnetic release according to the position of the door and / or door type detector, lock or snaps.

The trigger 2 is fixed on the axis 18 of the latch 10 via a removable jumper 19 to screw means 9.

In particular, in this embodiment preferred, detector 1 is provided with a discharge of the battery 20 and of a sensitive button 21, allowing the delay of the buzzer activation. In effect, thanks to this function, the inhabitant who pushed on this button when leaving the house, when it returns to it, has a delay, for example 10 seconds, to enter and close the door. Otherwise the alarm would sound immediately.

The sensitive button 22 allows you to place the detector powered on by pushing once and putting it out of service by pushing twice (switch "On / Off").

However, when the configuration of the detector has been chosen, just press the key sensitive 22 constantly for 10 seconds, and the detector is locked in "On" position. Then must press keys 21 and 24 simultaneously to return the detector to the "Off" position. This function is very useful to avoid decommissioning of the detector in case the button has been pressed accidentally, for example by a child, the woman of work, etc.

In the same spirit, we can also, in using the length of time a key is pressed or by pressing two keys simultaneously, access additional functions or applications. For example, we can thus modify the operating time of the buzzer.

The detector is also equipped with a indicator 23 indicating that the door latch has been operated. When the inhabitant returns to his house or his apartment, if the door catch has been activated during his absence, this indicator therefore allows him to ensure.

Unlike key 21, the key sensitive 24, when activated, activates the detector in instant mode. As soon as the latch is activated, the buzzer works instantly.

The detector is also provided with a connector 16, enabling various functions to be activated, among others the installation of a second buzzer, by example in the bedroom, to recharge the battery or supply the detector with voltage from a source auxiliary, or to connect the detector to a alarm center or a telephone transmitter.

The sensitive button 25 allows to neutralize operation of the detector during a period of 10 seconds for example, so as to allow the inhabitant leave your house without running the buzzer or the alarm.

The touch keys 21,22,24,25 are provided with electroluminescent indicators (LED), intended to allow the user to view the functions corresponding (activation or deactivation).

In this embodiment, the detector is fitted with a single magnetic switch 17, which is placed in the same axis as the trigger arm 2. From this done, magnet 7 permanently activates the switch magnetic 17. According to the direction of rotation of the latch 10, when magnet 7 will move to the left or the right, the magnetic switch 17 will no longer be sensitized. The contact will open and activate the detection and alarm process. It is the same in case of disassembly of the latch pin. The principle of operation is therefore reversed compared to the first preferred embodiment with two switches magnetic.

Finally, on the rear side, the detector is provided with a device 26 for engaging immediately the buzzer if the detector is removed or moved from its holder. This device is very useful for ensure the security of the detector.

Figures 2 and 4 show an example of installation of the device according to the invention on the door entrance to any building or apartment, fitted with most classic opening system with an axis provided with latches 10 and a movable lock 30. However, as already mentioned above, there can protect houses, apartments, garages, shops, offices, etc., at any door or window.

Although the detector alone is completely autonomous, it can ideally complete a existing alarm center to perform a function which, until now was completely ignored.
