Abstract

1. A security window comprising a recess in the counter (4, 4a) the median section of which is located unterneath a security glass panel (2, 2a) abutting the counter (1, 1a) on both sides of the recess (4, 4a), said recess consisting of at least one thin element (5, 6) capable of vibrating and further comprising the moving component of an electro acoustic transducer (7, 9) attached underneath said thin element so as to cause it to vibrate in the manner of a loudspeaker diaphragm when actuated by at least one microphone (11, 12), characterized in that the recess (4, 4a) consists of two half recesses (5, 6) separated by a joint (17) which prevents the vibrations of one the two half recesses (5, 6) from reaching the other half recess with each thin element which constitutes one half recess being located on one of the two opposite sides of the glass panel (2, 2a) and further being operatively connected to one electro acoustic transducer (7, 9) actuated by a microphone (11, 12), and in that the microphone (11, 12) actuating the electro acoustic transducer (7, 9) of one of the two half recesses (5, 6) is positioned underneath the other half recess.

Description

Dans son brevet suisse antérieur No 628391, l'auteur de la présente invention a décrit un guichet 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, qui est formée d'au moins une pièce mince capable de vibrer. L'équipage mobile d'un transducteur électro-acoustique est fixé sous la dite pièce mince pour la faire vibrer comme une membrane de haut-parleur sous la commande d'au moins un microphone. Ce guichet de sécurité s'est avéré efficace. Toutefois, il se présente une difficulté qui vient du fait que les microphones provoquent parfois des sifflements gênants (effet Larsen), qu'on ne peut éliminer, avec cette construction, qu'en cherchant par tâtonnement un autre emplacement des microphones. De plus, le fait d'avoir les microphones distants de la cuvette exige des fils de connexion.In his previous Swiss patent No 628391, the author of the present invention described a security window comprising a counter bowl, the middle part of which is placed flush with a security window extending to contact with the counter on each side of the bowl, which is formed of at least one thin piece capable of vibrating. The mobile assembly of an electro-acoustic transducer is fixed under the said thin part to make it vibrate like a loudspeaker membrane under the control of at least one microphone. This security window has proven to be effective. However, there is a difficulty which arises from the fact that the microphones sometimes cause annoying whistling (Larsen effect), which can only be eliminated with this construction by searching by trial and error for another location for the microphones. In addition, having the microphones distant from the cuvette requires connection wires.

L'auteur de la présente invention a trouvé que ces difficultés peuvent être éliminées en prévoyant:

  • 1. que la cuvette est formée de deux demi-cuvettes séparées par un joint isolant les deux demi-cuvettes l'une de l'autre du point de vue vibratoire;
  • 2. que la pièce mince constitutive de chacune des deux demi-cuvettes est disposée d'un côté de la vitre de sécurité et est associée à un transducteur électro-acoustique commandé par un microphone;
  • 3. que le microphone commandant le transducteur électro-acoustique de l'une des demi-cuvettes est disposé sous l'autre demi-cuvette.
The author of the present invention has found that these difficulties can be eliminated by providing:
  • 1. that the bowl is formed of two half-bowls separated by a seal isolating the two half-bowls from one another from the vibrational point of view;
  • 2. that the thin part constituting each of the two half-bowls is arranged on one side of the safety glass and is associated with an electro-acoustic transducer controlled by a microphone;
  • 3. that the microphone controlling the electro-acoustic transducer of one of the half-cuvettes is placed under the other half-cuvette.

Non seulement l'effet Larsen est ainsi supprimé grâce à une telle disposition, mais cette dernière a l'avantage supplémentaire que les microphones sont solidaires de la cuvette et sont mis en place en même temps que celle-ci. Ainsi les microphones ne sont plus apparents et tous fils de connexion de ces microphones à l'extérieur de la cuvette sont supprimés.Not only is the Larsen effect thus eliminated thanks to such an arrangement, but the latter has the additional advantage that the microphones are integral with the bowl and are put in place at the same time as the latter. Thus the microphones are no longer apparent and all the connection wires of these microphones outside the bowl are eliminated.

L'invention est conforme à la revendication 1.The invention is in accordance with claim 1.

Le dessin annexé représente, à titre d'exemple, une forme d'exécution et une variante du guichet de sécurité selon la présente invention.

  • Fig. 1 en est une vue en perspective.
  • Fig. 2 en est une coupe transversale selon 2-2 defig. 1.
  • Fig. est une vue analogue à la fig. 1, mais relative à une variante.
The accompanying drawing shows, by way of example, an embodiment and a variant of the security window according to the present invention.
  • Fig. 1 is a perspective view thereof.
  • Fig. 2 is a cross section according to 2-2 defig. 1.
  • Fig. is a view similar to FIG. 1, but relating to a variant.

Sur les fig. 1 et 2, on voit en 1 une partie d'un comptoir, de banque par exemple, et en 2 une vitre de sécurité séparant une moitié du comptoir se trouvant du côté des clients, de l'autre moitié se trouvant du côté du personnel de l'établissement.In fig. 1 and 2, we see in 1 part of a counter, for example a bank, and in 2 a safety glass separating half of the counter on the customer side, the other half on the staff side of the establishment.

Dans un évidement rectangulaire 3 du comptoir 1, s'étendant symétriquement des deux côtés de la vitre 2, est disposée une cuvette 4, de façon que son bord supérieur soit au niveau de la face supérieure du comptoir 1. La vitre 2 s'étend pratiquement jusqu'au contact avec cette face supérieure et avec le bord supérieur de la cuvette 3, comme on le voit sur la fig. 2.In a rectangular recess 3 of the counter 1, extending symmetrically on both sides of the glass 2, is arranged a bowl 4, so that its upper edge is at the level of the upper face of the counter 1. The glass 2 extends practically until contact with this upper face and with the upper edge of the bowl 3, as seen in FIG. 2.

La cuvette 4 est formée de deux demi-cuvettes 5, 6 séparées par un espace vide ou joint 17 que l'on remplit de préférence d'une matière ne transmettant pratiquement pas les vibrations mécaniques de l'une des demi-cuvettes à l'autre, telle que du caoutchouc ou une silicone. Chacune de ces demi-cuvettes est faite d'une pièce mince, métallique ou en matière plastique, capable de vibrer à la façon d'une membrane de haut-parleur.The bowl 4 is formed of two half-bowls 5, 6 separated by an empty space or joint 17 which is preferably filled with a material which practically does not transmit the mechanical vibrations of one of the half-bowls to the other, such as rubber or silicone. Each of these half-cups is made of a thin piece, metallic or plastic, capable of vibrating like a speaker membrane.

Un transducteur électro-acoustique 7 est fixé sous le bord 8 de la demi-cuvette 5, pour faire vibrer celle-ci comme une membrane de haut-parleur.An electro-acoustic transducer 7 is fixed under the edge 8 of the half-bowl 5, to vibrate the latter like a loudspeaker membrane.

Un transducteur identique 9 est fixé de même façon sous le bord 10 de la demi-cuvette 6 qui est opposé au bord 8.An identical transducer 9 is fixed in the same way under the edge 10 of the half-bowl 6 which is opposite to the edge 8.

Un microphone 11 est placé sous le bord 8 de la demi-cuvette 5 et sert à commander le transducteur 9 situé sous le bord 10 de l'autre demi-cuvette 6. De façon symétrique, un microphone 12 est placé sous le bord 10 et commande le transducteur 7 situé du côté opposé de la vitre de sécurité 2. Ainsi les personnes situées de part et d'autre du comptoir peuvent communiquer par la voix dans de bonnes conditions car l'expérience a montré qu'avec la disposition décrite en deux demi-cuvettes indépendantes du point de vue acoustique, avec le microphone de l'un des côtés de la vitre commandant le transducteur situé de l'autre côté de cette vitre, on évite complètement les défauts signalés au début.A microphone 11 is placed under the edge 8 of the half-bowl 5 and is used to control the transducer 9 located under the edge 10 of the other half-bowl 6. Symmetrically, a microphone 12 is placed under the edge 10 and controls the transducer 7 located on the opposite side of the safety glass 2. Thus the people located on either side of the counter can communicate by voice in good conditions because experience has shown that with the arrangement described in two acoustically independent half-bowls, with the microphone on one side of the glass controlling the transducer located on the other side of this glass, the faults reported at the start are completely avoided.

Des amplificateurs 14, 15 sont fixés sous la face inférieure des deuxdemi-cuvettes et il est prévu en 13 des boutons de réglage de la puissance des haut-parleurs. Ces boutons sont de préférence logés dans des cavités des demi-cuvettes et prévus pour être tournés avec un tournevis pour faire le réglage de puissance sonore de chacune des deux demi-cuvettes.Amplifiers 14, 15 are fixed under the underside of the two half-cuvettes and there are provided at 13 buttons for adjusting the power of the loudspeakers. These buttons are preferably housed in cavities of the half-cuvettes and designed to be turned with a screwdriver to adjust the sound power of each of the two half-cuvettes.

Ainsi toute la partie électrique est portée par les demi-cuvettes et est mise en place avec elle, d'un seul coup. Bien sûr, un câble non représenté permet de relier cette partie électrique à une prise de courant d'alimentation. Ce câble et cette prise sont prévus sous le comptoir, pour échapper à la vue des usagers du guichet.Thus all the electrical part is carried by the half-bowls and is put in place with it, all at once. Of course, a cable not shown makes it possible to connect this electrical part to a power outlet. This cable and this socket are provided under the counter, to escape the sight of users of the counter.

Le guichet décrit a donc l'avantage qu'aucun élément électrique (transducteurs, microphones, amplificateurs et leurs interconnexions) n'est visible des usagers.The window described therefore has the advantage that no electrical element (transducers, microphones, amplifiers and their interconnections) is visible to users.

La variante représentée sur la fig. 3 présente les mêmes avantages que la forme d'exécution selon fig. 1 et 2. Elle diffère de cette dernière sur les points suivants.The variant shown in FIG. 3 has the same advantages as the embodiment according to fig. 1 and 2. It differs from the latter in the following points.

La cuvette 4a - formée pareillement de deux demi-cuvettes - est fixée sur la face supérieure du comptoir 1 a, au lieu d'être encastrée dans une ouverture de celui-ci.Bowl 4a - similarly formed of two half-bowls - is fixed on the upper face of the counter 1 a, instead of being embedded in an opening of the latter.

En conséquence, la vitre de sécurité 2a présente sur son bord inférieur une échancrure 16 dans laquelle s'emboîte la cuvette 4a, au lieu d'avoir un bord rectiligne comme dans le cas des fig. 1 et 2.Consequently, the safety glass 2a has on its lower edge a notch 16 in which fits the bowl 4a, instead of having a straight edge as in the case of FIGS. 1 and 2.
