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 un perfectionnement apporté à une gâche sonore pour tous verrous. The subject of the invention is an improvement made to a sound strike for all locks.

L'inventeur a déjà déposé une demande de brevet principale le 16 octobre 1980 sous le n" 80 22424. The inventor already filed a main patent application on October 16, 1980 under No. 80 22424.

La demande principale décrit une gâche sonore utilisant une bombe aérosol placée horizontalement perpendiculairement au plan principal de la porte. Cette disposition n'est pas très satisfaisante en général pour les bombes aérosols qui doivent être tenues veticalement pour bien fonctionner. De plus cette disposition horizontale perpendiculaire au plan de la porte est encombrante. The main application describes a sound strike using an aerosol can placed horizontally perpendicular to the main plane of the door. This arrangement is not very satisfactory in general for aerosol cans which must be held vetically to function properly. In addition, this horizontal arrangement perpendicular to the plane of the door is bulky.

L'inventeur a donc créé un autre mode de réalisation qui permet de disposer la bombe aérosol ou tout autre moyen de détection analogue dans une position verticale parallèle au plan de la porte. The inventor has therefore created another embodiment which makes it possible to arrange the aerosol can or any other similar detection means in a vertical position parallel to the plane of the door.

La gâche contient, en entier, le moyen de détection qui est disposé verticalement parallèle au plan principal de la porte. The keeper contains, in full, the detection means which is arranged vertically parallel to the main plane of the door.

Au niveau de la partie supérieure le doigt d'un renvoi est disposé tandis que l'autre extrémité du renvoi se trouve au niveau du penne, ledit renvoi est monté pivotant sur un axe. At the upper part, the finger of a return is disposed while the other end of the return is at the pin, said return is pivotally mounted on an axis.

Les dessins ci-joints donnés à titre d'exemple permettent aisément de comprendre l'invention. Ils représentent un mode de réalisation préféré selon l'invention. The attached drawings given by way of example allow the invention to be easily understood. They represent a preferred embodiment according to the invention.

La figure 1 est une vue de dessus de l'appareil mis en place sur le chambranle de la porte et sur la porte. Figure 1 is a top view of the apparatus placed on the door frame and on the door.

La figure 2 est une vue de côté de l'appareil du côté de la gâche. Figure 2 is a side view of the apparatus from the strike side.

Dans les figures 1 et 2, le verrou 1 est fixé sur la porte 2, son penne 3 vient s'engager dans la gâche 16. La gâche 16 comporte un logement qui permet de disposer le moyen de détection 17, en l'occurence la bombe aérosol, verticalement et parallèlement au plan principal de la porte 2 ou au chambranle 6. In Figures 1 and 2, the latch 1 is fixed on the door 2, its pin 3 engages in the keeper 16. The keeper 16 has a housing which makes it possible to arrange the detection means 17, in this case the aerosol can, vertically and parallel to the main plane of door 2 or to frame 6.

Le sommet 18 du moyen de détection 17 est en contact avec
une extrémité 19 du renvoi 20 monté sur un axe 21 tandis que l'autre extrémité 22 est à une distance d du penne 3 du verrou
1.The top 18 of the detection means 17 is in contact with
one end 19 of the reference 20 mounted on an axis 21 while the other end 22 is at a distance d from the pin 3 of the latch
1.

On comprend donc que tout déplacement intempestif du penne 3 permettra d'actionner, par le renvoi 20, le moyen de détection 17. It is therefore understood that any untimely movement of the pin 3 will make it possible to actuate, by the reference 20, the detection means 17.

Celui-ci, dans le cas d'une bombe aérosol, comporte à son extrémité supérieure 18 un sifflet.The latter, in the case of an aerosol can, has a whistle at its upper end 18.

Il est également possible, pour la mise en place de la bombe aérosol 17 d'actionner une molette de réglage 23 qui règle en même temps la sensibilité dudit moyen de détection en faisant varier la distance d. It is also possible, for the installation of the aerosol can 17 to actuate an adjustment wheel 23 which at the same time adjusts the sensitivity of said detection means by varying the distance d.

Un capot 24 peut venir s'encastrer dans le logement de la gâche 16 de manière à protéger la bombe aérosol ou le moyen de détection 17 et à habiller l'ensemble du dispositif. A cover 24 can be recessed in the housing of the keeper 16 so as to protect the aerosol can or the detection means 17 and to cover the entire device.

Claims

RESELL ICAT IONS

1. Sound strike for all locks according to claim 1 of main patent nO 80 22424 filed October 16, 1980 characterized in that the strike (16) has a housing which allows to arrange the detection means (17), vertically and parallel in the main plane of the door (2) or of the jamb (6), the detection and action of the alarm signal being effected by one of its ends (18,17).

2. Sound strike for all locks according to claim 1 characterized in that the aerosol can (17) is disposed between the end (19) of a reference and the end of a knurled adjusting screw (23).

3. Sound strike for all locks according to any one of claims 1 or 2 characterized in that the end (18) is a whistle disposed on the head of the aerosol can (17), which is therefore in contact with the end (19) of a return (20) mounted on an axis (21).

4. Sound strike for all locks according to any one of claims 1, 2 or 3 characterized in that the wheel (23) allows the aerosol can to be held in place in its housing in the strike (16) but also the adjustment of the distance (d), therefore of the sensitivity of the device.

5. Sound strike for all locks according to any one of claims 1, 2, 3 or 4 characterized in that the strike (16) may include a cover (24) which fits into said strike to protect the bomb aerosol (17) and cover all of said striker.
