Abstract

The device can be used for protection against theft or attack. It comprises a solenoid valve 12 attached securely to an aerosol can 17 through a sealed connector 14. The pressure in the can is communicated fully to the inside of the body of the solenoid valve 12 during its installation in the device. Control of the solenoid valve is provided by an electronic circuit connected to a detection loop 1 composed equally well of either normally closed or normally open contacts. When the device is in its warning mode, any change in the state of the contact C excites the protection circuit 2 of the device, which supplies power to the control panel of the solenoid 11 of the solenoid valve 12. This causes an immediate programmable diffusion of the gases. The programming can be adjusted by two potentiometers P1 and P2 in Figure 2. The casing of the device is in two parts, one fixed on its support and the other detachable. The detachable part has a light-emitting diode indicator 5 on its outer surface, and this shows the state of the detection loop 1, the state of the gas pressure, and the condition of the batteries which power the device. The device is started up or put into its warning mode by an electric lock and a push button Bp. These control and monitoring elements can be removed.

Figure 1 is a block diagram showing a preferred mode of operation of the device, Figure 3 is a representation of the two parts of the container containing the device according to the invention with the referents s related elements. Before describing the operation of the device according to the invention, we will give the following definitions. The word "guard". means an operating standby state, the word "standby" defines an operational operating state, the word "NO" and "NF" respectively mean "normally" open and "normally closed", the word "Led" designates a diode electro-luminescent the term "detection loop" relates to a detection circuit consisting of volumetric detectors or with "NO" or NF "contacts specific to the room to be protected, and external to the device described.

Le dispositif selon l'invention est constitué d'un container se composant de deux parties, l'une fixée sur son support par deux vis, l'autre amovible comportant sur sa face externe, une serrure éléctrique à quatre plots, un orifice déstiné à l'échappement des gaz, et une "Led". Dans sa face interne se trouve fixée les circuits de commande et de mise en route. La partie fixe se partage en deux compartiments. Dans l'un est fixé l'éléctro-vanne ainsi qu'une bombe de gaz genre aérosol. Dans l'autre se trouve la source d'énérgie constituée par trois piles alcalines de 9 volts.The device according to the invention consists of a container consisting of two parts, one fixed to its support by two screws, the other removable comprising on its external face, an electric lock with four studs, an orifice intended for exhaust gas, and an "LED". On its internal face is fixed the control and start-up circuits. The fixed part is divided into two compartments. In one is fixed the solenoid valve as well as an aerosol-type gas bomb. In the other is the energy source consisting of three 9-volt alkaline batteries.

La déscription va maintenant être faite en fonction des définitions pré-citées. La mise en place de la cartouche à gaz 17s'éffec- tue manuellement en enfonçant l'embout cylindrique 15 à l'intérieur du raccord d'étanchéité 14 qui est solidaire du corps de l'éléctro-vanne 12. L'intérieur de ce raccord 14 comporte sur une distance déterminée par la course de l'embout 15 un rétrécissement de son diamètre qui va assurer une fonction de butée, limitant la course de l'embout cylindrique 15 à l'intérieur du raccord 14. En appuyant la bombe 17 nous allons enfoncer cet embout 15 et communiquer ainsi la préssion de la bombe 17 à l'intérieur du corps de l'éléctro-vanne 12. L'étanchéité est assurée par un joint torique logé dans une gorge à l'intérieur du raccord 14.The description will now be made according to the aforementioned definitions. The gas cartridge 17 is put in place manually by pushing in the cylindrical end piece 15 inside the sealing connection 14 which is integral with the body of the solenoid valve 12. The interior of this connector 14 comprises over a distance determined by the stroke of the end piece 15 a narrowing of its diameter which will ensure a stop function, limiting the stroke of the cylindrical end piece 15 inside the connector 14. By pressing the bomb 17 we are going to insert this end-piece 15 and thus communicate the pressure of the bomb 17 inside the body of the solenoid valve 12. The seal is ensured by an O-ring housed in a groove inside the fitting 14.

Le maintient de la bombe 17 est assuré par une vis à tête mol- letée dont l'écrou est solidaire de l'embase du logement de la bombe 17.Cette déscription fait resortir une des caractéristiques importante du dispositif selon l'invention, à savoir la transmission constante de la pression de la bombe à l'intérieur du corps de l'éléctro-vanne. En référance au mode de réalisation du dispositif selon l'invention, illustré par la figure 1 , la boucle de détéction 1 est constituée de contacts "NF" , elle est insérée en série dans le circuit de protéction 2 du dispositif selon l'invention. Le circuit de protection 2 propre au dispositif selon l'invention est constitué par une serrure éléctrique à quatre plots, par trois micro-relais à contacts multiples, d'une "Led" de signalisation et d'un bouton poussoir "Bp". Le circuit éléctronique représenté sur la figure 2 est l'organe de commande du solénoide de l'éléctro-vanne 7 , il à été réalisé à partir de données connues et adapté aux besoins du dispositif selon l'invention. Il est constitué par deux C.I. 18 et 19 qui sont des oscillateurs et dont la durée des impulsions actives sont réglées par les potentiomètres P1 et P2 figurant sur la figure 2, de deux ensembles de comptages 20 et 21, d'un système de présélection prioritaire 22 et d'un dispositif d'inversion de comptage 23 en fin de phase. Lorsque les oscillateurs 18 et 19 sont éxcités par les bornes 6 et 7 du circuit de protection du dispositif selon l'invention, seules les informations de l'oscillateur 18 sont prises en considération en début de processus, et cela par la séléction prioritaire efféctuée par le C.I. 22 dont la sortie alimente directement l'ampli 24 qui éxcite le relais 25 qui va alimenter l'éléctro-vanne. L'interposition du C.I. 22 représente une caractéristique intéressante du dispositif de commande du solénoide de l'éléctro-vanne 12, en effet quel que soit le cycle en fonction lors de l'arrêt d'une alarme, de par le C.I. 22 faisant une séléction prioritaire, lors d'une nouvelle excitation des oscillateurs 18 et 19 seule la phase active de l'oscillateur 18 sera prise en considération et permettra une commande immédiate de l'éléctro-vanne 12.The bomb 17 is maintained by a knurled screw whose nut is secured to the base of the bomb housing 17. This description makes one of the important characteristics of the device according to the invention stand out, namely the constant transmission of the bomb pressure inside the body of the solenoid valve. With reference to the embodiment of the device according to the invention, illustrated in FIG. 1, the detection loop 1 is made up of "NC" contacts, it is inserted in series in the protection circuit 2 of the device according to the invention. The protection circuit 2 specific to the device according to the invention is constituted by an electric lock with four studs, by three micro-relays with multiple contacts, a "Led" signaling and a push button "Bp". The electronic circuit shown in Figure 2 is the solenoid control member of the solenoid valve 7, it was produced from known data and adapted to the needs of the device according to the invention. It consists of two ICs 18 and 19 which are oscillators and whose duration of the active pulses are regulated by the potentiometers P1 and P2 appearing in FIG. 2, two sets of counters 20 and 21, a priority preselection system 22 and a counting reversal device 23 at the end of the phase. When the oscillators 18 and 19 are excited by the terminals 6 and 7 of the protection circuit of the device according to the invention, only the information of the oscillator 18 is taken into consideration at the start of the process, and this by the priority selection made by the IC 22 whose output directly feeds the amplifier 24 which energizes the relay 25 which will supply the solenoid valve. The interposition of the IC 22 represents an interesting characteristic of the solenoid control device of the solenoid valve 12, in fact whatever the cycle in operation when the alarm is stopped, by the IC 22 making a priority selection, during a new excitation of oscillators 18 and 19 only the active phase of oscillator 18 will be taken into account and will allow immediate control of the solenoid valve 12.

Nous allons maintenant expliquer le fonctionnement du dispositif selon l'invention et conformément à la figure 1.We will now explain the operation of the device according to the invention and in accordance with FIG. 1.

Lors de la mise sous tension du circuit de protéction 2 par l'action de la clef 3 sur la serrure électrique 4, un signal lumineux apparait, matérialisé par une "Led" sur la face externe de la partie amovible 27 du container représenté sur la figure 3. cette "Led" nous indique l'état opérationnel du circuit de détection 1 perméttant à ce moment là et à ce moment uniquement, la mise sous tension du relai R1, qui assure par son contact R11 le passage du courant à travers le contact R21 du relai R2 qui est encore au repos, va alimenter la "LED" de controle 5. Ce n'est donc qu'après avoir vérifier le circuit de détéction 1 qu'il est .possible d'alimenter le circuit de protéction 2. Cette mise en état de veille va être obtenu par le bouton poussoir Bp. Ce bouton poussoir va assurer l'alimentation du relai R2 et par voie de conséquence, "ouverture du contact R21, coupant l'alimentation de la "Led" 5 signalant ainsi que le dispositif selon l'invention est opérationnel. L'alimentation du relai R21 provoque la fermeture de son contact R22 et une auto-alimentation du contact R22 lorsque l'on relachera le bouton poussoir Bp.When the protection circuit 2 is energized by the action of the key 3 on the electric lock 4, a light signal appears, materialized by a "Led" on the external face of the removable part 27 of the container shown in the figure 3. this "Led" indicates the operational state of the detection circuit 1 permitting at this time there and at this time only, the energization of the relay R1, which ensures by its contact R11 the passage of current through the contact R21 of relay R2 which is still at rest, will supply the control "LED" 5. It is therefore only after having checked the detection circuit 1 that it is .possible to supply the protection circuit 2 This standby state will be obtained by the push button Bp. This push button will ensure the supply of the relay R2 and consequently, "opening of the contact R21, cutting the supply of the" Led "5 signaling as well as the device according to the invention is operational. R21 causes the closure of its contact R22 and a self-supply of the contact R22 when the push button Bp is released.

Dès lors d'un changement d'état d'un des contacts C du circuit de détection 1, le relai R1 ne sera plus alimenté, provoquant la retombée du contact R12 qui va mettre sous tension le relai R3 et par le contact R31 de celui-ci, provoqué l'alimentation du solénoide 11 de l'éléctro-vanne 12 qui va libérer les gaz par l'orifice 13 situé sur la face 27 du container. Ce procéssus d'alarme ne pourra pas être arrêté en refermant par exemple une porte pour remettre un contact du circuit de détéction dans son état initial, en effet en provoquant l'alimentation du relai R3 on provoque également son auto-alimentation par le contact R31. Au terme de cette déscription il est compréhensible que le dispositif selon l'invention puisse être inséré dans n'importe quelle installation d'alarme déjà existante, dans quel cas son alimentation pourra se faire avec la source d'alimentation de l'installation. Il nous reste à éxpliquer deux aspects pratiques du dispositif selon l'invention, l'un concernant l'état de pression des gaz contenus dans la bombe 17, l'autre la vérification de l'état des piles alimentant le dispositif selon l'invention.As soon as there is a change in state of one of the contacts C of the detection circuit 1, the relay R1 will no longer be supplied, causing the contact R12 to drop which will energize the relay R3 and by the contact R31 thereof, caused the supply of the solenoid 11 of the solenoid valve 12 which will release the gases through the orifice 13 located on the face 27 of the container. This alarm process cannot be stopped by closing, for example, a door to restore a contact of the detection circuit to its initial state, in fact by causing the supply of the relay R3 it also causes its self-supply by the contact R31 . At the end of this description, it is understandable that the device according to the invention can be inserted into any already existing alarm installation, in which case it can be supplied with the installation's power source. It remains for us to explain two practical aspects of the device according to the invention, one concerning the state of pressure of the gases contained in the bomb 17, the other the verification of the state of the batteries supplying the device according to the invention .

Lors de la mise en place de la bombe 17; nous avons expliqué qu'à travers le conduit du raccord étanche 14, la préssion de la bombe était intégralement transmise à l'intérieur du corps de l'éléctro-vanne.Cette préssion est également restituée par un orifice se trouvant sur le raccord d'étanchéité 14 à un dispositif de contrôle constitué par une membrane conductrice,souple et étanche. Elle subit en sa partie supérieure une force antagoniste à la poussée des gaz et tarée de telle sorte que lorsque le seuil de préssion des gaz va devenir critique, cette membrane en s'abaissant va fermer un contact du dispositif de contrôle 16 et permettre à travers la serrure électrique 4 celle-ci étant dans la position "repos"ou "garde" de mettre sous tension la "Led" 5, signalant le défaut. Pour éviter dans cette position de la serrure un retour de courant qui alimenterait d'une manière intempestive le circuit de protection du dispositif selon l'invention; une diode est implantée entre la "Led" 5 et le contact 21 comme le montre la fige 1. Pour des raisons d'autonomie nous avons volontairement limité cette information, le dispositif selon l'invention étant au repos c'est à dire en position "garde" ce qui laisse supposer que les locaux sont occupés et le signal perçu. Lorsque le dispositif selon l'invention est utilisé d'une manière autonome, son alimentation est assurée par trois piles alcalines de 9 volts logées dans la partie fixe du container 26 prévue à cet effet. Le contrôle de l'état des piles peut être fait à tout instant en appuyant sur le bouton poussoir Bp dont deux bornes prévues à cet effet permettent le passage du courant à travers les contacts B6 et B7 du dispositif éléctronique figure 2 'et provoquer l'alimentation de la "Led" de contrôle 5.When placing the bomb 17; We have explained that through the conduit of the tight fitting 14, the pressure of the bomb was fully transmitted inside the body of the solenoid valve. This pressure is also restored by an orifice located on the fitting. sealing 14 to a control device constituted by a conductive, flexible and waterproof membrane. It undergoes in its upper part a force antagonistic to the thrust of the gases and calibrated so that when the pressure threshold of the gases becomes critical, this membrane by lowering will close a contact of the control device 16 and allow through the electric lock 4, the latter being in the "rest" or "guard" position to switch on the "Led" 5, signaling the fault. To avoid in this position of the lock a current return which would inadvertently supply the protection circuit of the device according to the invention; a diode is installed between the "Led" 5 and the contact 21 as shown in fig. 1. For reasons of autonomy we have voluntarily limited this information, the device according to the invention being at rest, that is to say in position "guard" which suggests that the premises are occupied and the signal perceived. When the device according to the invention is used autonomously, it is supplied by three 9-volt alkaline batteries housed in the fixed part of the container 26 provided for this purpose. The battery status can be checked at any time by pressing the push button Bp, including two terminals provided for this purpose allow the current to flow through the contacts B6 and B7 of the electronic device in Figure 2 'and cause the supply to the control "Led" 5.

Le dispositif selon l'invention devrait trouver une place prépondérante sur le marché devant la recrudescence constante des cambriolages et dans la diminution constante du pouvoir dissuasif des alarmes sonores. Le dispositif selon l'invention trouvera une place prépondérante pour renforcer toute installation éxistante ou à venir, en particulier pour la protéction des voitures ainsi que des locaux démunis de source d'éléctricité.The device according to the invention should find a prominent place on the market in the face of the constant upsurge in burglaries and in the constant decrease in the deterrent power of audible alarms. The device according to the invention will find a preponderant place to reinforce any existing or future installation, in particular for the protection of cars as well as deprived premises of source of electricity.
