Abstract

The door lock uses an aerosol can which when contacted by the bolt (3) of the lock (1) discharges gas so as to cause a whistle (13) to sound. Attached to the frame (6) adjacent to the edge of the door (2) is a strip (4) bent into a U shape, acting as a door catch. One arm (7) is secured to the door frame by screws, and the parallel arm (9) carries an externally threaded tube (10) locked by a ring nut (11). Inside the tube, the aerosol can is inserted, with its base (15) projecting towards the bolt, spaced from it by a short gap (d). When the door is forced from the outside, the bolt is pushed against the aerosol can so that it is operated at the valve end, and gas is expelled into the whistle which is mounted onto the can by a flange (14). In another design, the bolt is forced against a crank arm which is tilted about an axis to operate against the aerosol can which is supported vertically, with an adjusting screw underneath.

Description

L'invention a pour objet une gâche sonore pour verrous. The subject of the invention is a sound keeper for locks.

Les dispositifs d'alarme qui existent sur les verrous actuels sont compliqués, d'un coût de fabrication élevé et nécessitent d'être posés par des techniciens. The alarm devices which exist on current locks are complicated, of a high manufacturing cost and require to be installed by technicians.

L'invention évite tous ces inconvénients. The invention avoids all these drawbacks.

L'invention est caractérisé par le fait que directement sur la gâche est disposé un moyen de détection qui actionne un signal dès que le penne du verrou vient en contact, latéralement avec ledit moyen de détection. The invention is characterized in that directly on the keeper is disposed a detection means which actuates a signal as soon as the pin of the lock comes into contact, laterally with said detection means.

Des moyens de réglage disposés sur la gâche permettent de régler le déplacement latéral du penne, pour lequel ledit signal est actionné. Ledit moyen de détection peut-être un contact électrique qui actionne alors le signal d'alarme. Le moyen de détection peut être purement mécanique, dans le cas où il s'agit d'une partie mobile d'une bombe aérosol placée judicieusement dans la gâche et dont la sortie du fluide actionne un signal d'alarme, sous l'action du déplacement du penne. Adjustment means arranged on the keeper make it possible to adjust the lateral displacement of the pin, for which said signal is actuated. Said detection means may be an electrical contact which then activates the alarm signal. The detection means can be purely mechanical, in the case where it is a mobile part of an aerosol can judiciously placed in the keeper and whose output of the fluid activates an alarm signal, under the action of the displacement of the pin.

La gâche, selon l'invention, est fixée au chambranle par un côté, tandis que 1' autre côté comporte un moyen de fixation tel qu'un orifice qui permet le passage d'un tube fileté qui peut contenir et laisser le passage à une bombe aérosol. Ledit tube comporte, de part en part de la gâche, des bagues de réglages. The keeper, according to the invention, is fixed to the doorframe by one side, while the other side comprises a fixing means such as an orifice which allows the passage of a threaded tube which can contain and allow passage to a spray can. Said tube comprises, on both sides of the keeper, adjustment rings.

La bague intérieure à la gâche sert à régler la profondeur du tube fileté dans la gâche donc le déplacement du penne par lequel le moyen de détection actionne le signal. La bague extérieure à la gâche assure la fixation de la bombe aérosol dans le tube fileté.The inner ring of the keeper is used to adjust the depth of the threaded tube in the keeper, therefore the displacement of the pin by which the detection means actuates the signal. The outer ring of the keeper secures the aerosol can in the threaded tube.

Le tube fileté peut, bien entendu, contenir des piles électriques qui alimentent et actionnent ledit signal d'alarme lorsque le moyen de détection est actionné par le penne. The threaded tube can, of course, contain electric batteries which supply and activate said alarm signal when the detection means is actuated by the pin.

Les dessins ci-joints donnés à titre d'exemple indicatif et non limitatif représentent un mode de réalisation préféré selon l'invention. The attached drawings given by way of indicative and nonlimiting example represent a preferred embodiment according to the invention.

Ces dessins permettront aisément de comprendre l'invention. These drawings will easily make it possible to understand the invention.

La figure 1 est une vue en plan de la gâche sonore, selon l'invention, une fois mise en place. Figure 1 is a plan view of the sound strike, according to the invention, once in place.

La figure 2 est une vue de la gâche sonore, vue de côté, avec une vue éclatée des differentes pièces. Figure 2 is a view of the sound strike, side view, with an exploded view of the different parts.

Dans la figure 1, le verrou 1 est fixé sur la porte 2, son penne 3 vient s'engager dans la gâche 4 qui est fixée par des vis tire-fonds 5 sur le chambranle 6 de la porte 2 par sa partie 7, qui est contre ledit chambranle 6, tandis que la partie extérieure 8 de la gâche reçoit dans un orifice 9 un tube fileté 10. Le tube fileté 10 peut être plus ou moins engagé à l'intérieur de la gâche 4, après réglage de la distance d, il est- maintenu en plan par une bague de réglage 11. Cette bague de réglage 11 permet de maintenir le tube fileté 10 en place, ou tout autre moyen de détection, après que la distance d ait été choisie.Cette distance d correspond au déplacement latéral d du penne 3, lorsqu'on veut forcer la porte 2 et que l'on force sur la serrure avec ou sans instrument
Le tube fileté 10 fait office de logement pour la bombe aérosol 12. Ladite bombe aérosol 12 est maintenue dans ledit tube par un épaulement et par la bague de fixation 14 qui assure la fixation du corps de la bombe aérosol 12 et du signal d'alarme 13, en l'occurence un sifflet qui est actionné lorsque le fond 15 de la bombe aérosol, qui fait office de moyen de détection 15, est poussé vers la tête de la bombe aérosol 12 qui envoie alors du gaz dans le sifflet 13.In Figure 1, the latch 1 is fixed on the door 2, its pin 3 engages in the keeper 4 which is fixed by lag screws 5 on the frame 6 of the door 2 by its part 7, which is against said jamb 6, while the outer part 8 of the keeper receives in a hole 9 a threaded tube 10. The threaded tube 10 can be more or less engaged inside the keeper 4, after adjusting the distance d , it is held in plan by an adjusting ring 11. This adjusting ring 11 keeps the threaded tube 10 in place, or any other detection means, after the distance d has been chosen. This distance d corresponds to the lateral movement d of the pin 3, when we want to force the door 2 and that we force on the lock with or without instrument
The threaded tube 10 acts as a housing for the aerosol can 12. Said aerosol can 12 is held in said tube by a shoulder and by the fixing ring 14 which secures the body of the aerosol can 12 and the alarm signal 13, in this case a whistle which is actuated when the bottom 15 of the aerosol can, which acts as detection means 15, is pushed towards the head of the aerosol can 12 which then sends gas into the whistle 13.

Comme on peut le constater, la gâche sonore, selon l'invention, peut être adaptée aisément sur n'importe quel type de verrous actuels. Il suffit de remplacer quelques vis 5 et de régler une bague 11. As can be seen, the sound strike, according to the invention, can be easily adapted to any type of current locks. Just replace a few screws 5 and adjust a ring 11.

Bien entendu, à la place du tube, il est possible de disposer tout autre logement et à la place de la bombe aérosol une réserve d'energie qui actionne un signal d'alarme quelconque. Of course, in place of the tube, it is possible to have any other housing and in place of the aerosol can an energy reserve which activates any alarm signal.
