Abstract

The object of this window is to improve the sound communication between the two sides of a window pane, without decreasing safety. It comprises a tray (3) of a counter (1) whose central part is placed flush below a safety window pane (2). This tray is formed by a sheet supported by its edges. The movable element of an electroacoustic transducer (9) is fastened to one part of the lower face of the tray (3), in order to make the latter vibrate like a loudspeaker diaphragm. Microphones placed on both sides of the window pane (2) control the transducer, which makes it possible to talk from one side of this window pane to the other. <IMAGE>

Dans les banques, bureaux de poste et autres lieux publics où se font des paiements en espèces, on utilise de plus en plus des guichets de sécurité comprenant une cuvette de comptoir dont la partie médiane est disposée à fleur au-dessous d'une vitre de sécurité s'étendant jusqu'au contact avec le comptoir de chaque côté de la cuvette. Ces vitres de sécurité sont simples ou multiples et ont jusqu'à plusieurs centimètres d'épaisseur de façon à ne pas laisser traverser des balles de pistolet. Il se présente toutefois une difficulté pratique avec de tels guichets de sécurité: la communication verbale entre le client se trouvant d'un côté du comptoir et le personnel se trouvant de l'autre côté est assez difficile car une vitre aussi épaisse ne laisse pratiquement pas passer le son.On a prévu de faire de petites perforations à travers la vitre de sécurité, mais outre que cela constitue un affaiblissement mécanique, la transmission n'est satisfaisante que si la personne qui parle et celle qui écoute sont suffisamment rapprochées de la partie perforée du vitrage. In banks, post offices and other public places where cash payments are made, more and more security counters are being used, including a counter basin, the middle part of which is flush with a glass window. security extending until contact with the counter on each side of the bowl. These safety glasses are single or multiple and up to several centimeters thick so as not to let gun bullets pass through. There is however a practical difficulty with such security counters: verbal communication between the customer on one side of the counter and the staff on the other side is quite difficult because such thick glass leaves practically no Pass the sound. We plan to make small perforations through the safety glass, but in addition to this being a mechanical weakening, the transmission is only satisfactory if the person speaking and the person listening is sufficiently close to the game. perforated glazing.

La présente invention vise à éviter cet inconvénient et à fournir un guichet de sécurité dans lequel le vitrage soit continu, exempt de toute perforation, la communication sonore entre les deux côtés de la vitre étant néanmoins assurée de façon parfaite. Le guichet de sécurité selon l'invention se caractérise par le fait que la cuvette est formée par une feuille supportée par ses bords, et en ce que l'équipage mobile d'un transducteur électro-acoustique est fixé sur une partie de la face inférieure de la cuvette, pour faire vibrer celle-ci comme une membrane de haut-parleur sous la commande de microphones disposés des deux côtés de la vitre de sécurité, pour assurer la communication vocale entre des personnes se trouvant des deux côtés du comptoir. The present invention aims to avoid this drawback and to provide a security window in which the glazing is continuous, free of any perforation, the sound communication between the two sides of the glass being nevertheless perfectly ensured. The security window according to the invention is characterized in that the bowl is formed by a sheet supported by its edges, and in that the movable assembly of an electro-acoustic transducer is fixed on a part of the lower face of the bowl, to vibrate it like a speaker membrane under the control of microphones arranged on both sides of the safety glass, to ensure voice communication between people on both sides of the counter.

Le dessin annexé représente à titre d'exemple deux formes d'exécution du guichet de sécurité selon l'invention. The accompanying drawing shows by way of example two embodiments of the security window according to the invention.

Fig. I est une vue en perspective partielle de la première forme d'exécution. Fig. I is a partial perspective view of the first embodiment.

Fig. 2 est une vue en coupe transversale selon 2-2 de la fig. 1. Fig. 2 is a cross-sectional view along 2-2 of FIG. 1.

Fig. 3 est une vue analogue à la fig. 1 et relative à la deuxième forme d'exécution. Fig. 3 is a view similar to FIG. 1 and relating to the second embodiment.

Sur la fig. 1, on voit en 1 le comptoir, en 2 une vitre de sécurité et en 3 la cuvette permettant le passage des documents ou des espèces d'un côté à l'autre de la vitre 2. On voit que le bord inférieur de la vitre de sécurité 2 s'étend horizontalement sur le comptoir et au-dessus de la cuvette 3 en affleurant celle-ci. La cuvette est encastrée dans le comptoir de manière que sa partie supérieure soit à fleur avec la surface supérieure du comptoir. Cette cuvette 3 est constituée par une feuille mince, de préférence une tôle métallique emboutie dont les bords sont repliés, comme on le voit en 4 et fixés en 5 sur une plaque massive 6 fixée elle-même, par exemple par collage, dans un alvéole 7 du comptoir 1. La cuvette 3 présente à l'une de ses extrémités une partie plane 8 contre laquelle est fixé l'équipage mobile d'un transducteur électro-acoustique 9.On a représenté schématiquement en pointillés sur la fig. 2 I'emplacement de ce transducteur 9 dans l'espace compris entre la cuvette 3 et la plaque 6. Un microphone non représenté est disposé de chaque côté de la vitre de sécurité 2 dans un endroit pas trop éloigné du guichet mais de préférence dissimulé à la vue et ces microphones sont reliés par l'intermédiaire d'un amplificateur à l'enroulement du transducteur 9. In fig. 1, we see in 1 the counter, in 2 a safety glass and in 3 the bowl allowing the passage of documents or cash from one side to the other of the glass 2. We see that the lower edge of the glass security 2 extends horizontally on the counter and above the bowl 3 by being flush with the latter. The bowl is embedded in the counter so that its upper part is flush with the upper surface of the counter. This bowl 3 consists of a thin sheet, preferably a stamped metal sheet whose edges are folded, as seen in 4 and fixed in 5 on a solid plate 6 fixed itself, for example by gluing, in a cell 7 of the counter 1. The bowl 3 has at one of its ends a flat part 8 against which is fixed the movable assembly of an electro-acoustic transducer 9.We have been shown diagrammatically in dotted lines in FIG. 2 the location of this transducer 9 in the space between the bowl 3 and the plate 6. A microphone (not shown) is arranged on each side of the safety glass 2 in a location not too far from the window but preferably hidden from the view and these microphones are connected via an amplifier to the winding of the transducer 9.

La cuvette est disposée, comme on le voit, de manière que sa partie médiane soit au-dessous de la vitre de sécurité. Ainsi, lorsque soit le client, soit l'employé se trouvant de l'autre côté de la vitre parle, le microphone correspondant fait travailler le transducteur 9 qui met en vibration la membrane que constitue la cuvette 3, exactement comme s'il s'agissait d'une membrane de haut-parleur et ainsi le message est audible à la personne se trouvant du côté de la vitre opposé à celui où se trouve la personne qui parle. The bowl is arranged, as can be seen, so that its middle part is below the safety glass. Thus, when either the client or the employee on the other side of the window speaks, the corresponding microphone makes the transducer 9 work, which vibrates the membrane that constitutes the bowl 3, exactly as if it were acted as a loudspeaker diaphragm and so the message is heard by the person on the side of the glass opposite that of the person speaking.

Dans l'exemple selon fig. 3, la construction de la cuvette est tout à fait analogue, mais elle est fixée par la plaque 6 directement sur le comptoir la qui, lui, est dépourvu d'alvéole. Dans ce cas, la vitre de sécurité 2a présente une découpe 10 encadrant exactement la cuvette et sa plaque de base 6. On a représenté schématiquement en 9a l'emplacement du transducteur assurant la communication acoustique entre les deux côtés de la vitre 2a. In the example according to fig. 3, the construction of the bowl is completely similar, but it is fixed by the plate 6 directly on the counter which, itself, has no cell. In this case, the safety glass 2a has a cutout 10 exactly framing the bowl and its base plate 6. The location of the transducer ensuring acoustic communication between the two sides of the glass 2a is shown schematically at 9a.

In banks, post offices and other public places where cash payments are made, more and more security counters are being used, including a counter basin, the middle part of which is flush with a glass window. security extending until contact with the counter on each side of the bowl. These safety glasses are single or multiple and up to several centimeters thick so as not to let gun bullets pass through. There is however a practical difficulty with such security counters: verbal communication between the customer on one side of the counter and the staff on the other side is quite difficult because such thick glass leaves practically no Pass the sound. We plan to make small perforations through the safety glass, but in addition to this being a mechanical weakening, the transmission is only satisfactory if the person speaking and the person listening is sufficiently close to the game. perforated glazing.

The present invention aims to avoid this drawback and to provide a security window in which the glazing is continuous, free of any perforation, the sound communication between the two sides of the glass being nevertheless perfectly ensured. The security window according to the invention is characterized in that the bowl is formed by a sheet supported by its edges, and in that the movable assembly of an electro-acoustic transducer is fixed on a part of the lower face of the bowl, to vibrate it like a speaker membrane under the control of microphones arranged on both sides of the safety glass, to ensure voice communication between people on both sides of the counter.

Fig. I is a partial perspective view of the first embodiment.

Fig. 2 is a cross-sectional view along 2-2 of FIG. 1.

Fig. 3 is a view similar to FIG. 1 and relating to the second embodiment.

In fig. 1, we see in 1 the counter, in 2 a safety glass and in 3 the bowl allowing the passage of documents or cash from one side to the other of the glass 2. We see that the lower edge of the glass security 2 extends horizontally on the counter and above the bowl 3 by being flush with the latter. The bowl is embedded in the counter so that its upper part is flush with the upper surface of the counter. This bowl 3 consists of a thin sheet, preferably a stamped metal sheet whose edges are folded, as seen in 4 and fixed in 5 on a solid plate 6 fixed itself, for example by gluing, in a cell 7 of the counter 1. The bowl 3 has at one of its ends a flat part 8 against which is fixed the movable assembly of an electro-acoustic transducer 9.We have been shown diagrammatically in dotted lines in FIG. 2 the location of this transducer 9 in the space between the bowl 3 and the plate 6. A microphone, not shown, is arranged on each side of the safety glass 2 in a location not too far from the window but preferably concealed from the view and these microphones are connected via an amplifier to the winding of the transducer 9.

The bowl is arranged, as can be seen, so that its middle part is below the safety glass. Thus, when either the customer or the employee on the other side of the window speaks, the corresponding microphone makes the transducer 9 work, which vibrates the membrane that constitutes the bowl 3, exactly as if it were acted as a loudspeaker diaphragm and so the message is heard by the person on the side of the glass opposite that of the person speaking.

In the example according to fig. 3, the construction of the bowl is completely similar, but it is fixed by the plate 6 directly on the counter which, itself, has no cell. In this case, the safety glass 2a has a cutout 10 exactly framing the bowl and its base plate 6. The location of the transducer ensuring acoustic communication between the two sides of the glass 2a is shown schematically at 9a.
