Description

La présente invention se rapporte à une alimentation autonome pour boitier de télécommande infrarouge de teléviseur permettant l'alimentation du boîtier par le secteur. The present invention relates to a stand-alone power supply for an infrared remote control unit for a television enabling the unit to be supplied by the sector.

I1 est connu de télécommander un téleviseur à l'aide d'un boîtier de telécommande comportant un émetteur infrarouge par l'intermédiaire duquel sont transmis des ordres, tels que mise en marche, changement de chaîne etc.., à un récepteur infrarouge situé sur la face avant du teléviseur. Cette telécommande infrarouge conçue par les constructeurs pour le grand public a un boîtier de télécommande autonome alimenté par piles. I1 is known to remote control a television using a remote control unit comprising an infrared transmitter through which are transmitted commands, such as start, change channels etc., to an infrared receiver located on the front of the TV. This infrared remote control designed by manufacturers for the general public has an autonomous remote control box powered by batteries.

Cependant, ceci constitue dans certaines applications spécifiques un inconvénient réel. En effet, dans le cas de la location de televiseursaux collectivités, telles qu'hôpitaux, hôtels etc ., il est nécessaire de prévoir une ou plusieurs visites d'entretien par an pour changer les piles, ce qui entraine des frais correspondants. Un autre inconvénient sérieux constaté est le vol soit des piles, soit du boîtier lui-même. However, this constitutes in certain specific applications a real drawback. Indeed, in the case of rental of televisions to communities, such as hospitals, hotels etc., it is necessary to plan one or more maintenance visits per year to change the batteries, which entails corresponding costs. Another serious drawback noted is the theft either of the batteries or of the case itself.

Une première solution proposée consiste à utiliser une télécommande à fil au lieu d'une télécommande à infra- rouge. On s'affranchit ainsi du besoin d'une pile et le fait que le boîtier soit muni d'un cordon de raccordement terminé par une fiche de connexion dissuade pratiquement toujours l'utilisateur d'emporter le boîtier. En effet, il semble que l'utilisateur moyen soit ainsi amené à penser qu'un tel boS tier ne pourra pas être utilise avec des appareils standard. A first proposed solution consists in using a wired remote control instead of an infrared remote control. This eliminates the need for a battery and the fact that the housing is provided with a connection cord terminated by a connection plug almost always dissuades the user from carrying the housing. Indeed, it seems that the average user is thus led to think that such a boS tier cannot be used with standard devices.

Cependant cette solution a l'inconvénient qu'elle impose dans le local du client de l'entreprise de location une installation de fils, d'où frais supplémentaires. However, this solution has the drawback that it requires installation of wires on the premises of the customer of the rental company, hence additional costs.

La présente invention a pour obJet une alimentation autonome de boîtier de télécommande infrarouge remédiant à cet inconvénient. The object of the present invention is to provide an autonomous power supply for an infrared remote control unit which overcomes this drawback.

Selon l'invention, il est prévu une alimentation autonome de boitier de télécommande infrarouge de téléviseur permettant l'alimentation du boîtier par le secteur caractérisée en ce que ladite alimentation comprend un circuit de conversion de la tension secteur en une tension continue de valeur convenable, dont les composants sont disposés sur une carte de circuit imprimé, un boîtier fermé pouvant être fi xé au mur pour abriter ladite carte, un cordon de raccordement secteur dont une extrémité est raccordée audit circuit sur la carte à l'intérieur du boîtier et dont l'autre extrémité est termine par une prise de courant, et une embase de connexion femelle fixée sur le boîtier de l'alimentation pour la sortie de la tension continue et en ce que le boîtier de télécommande comporte un cordon de raccordement terminé par une fiche de connexion mâle pour le raccordement au boîtier d'alimentation. According to the invention, provision is made for an autonomous power supply for an infrared remote control box for a television enabling the box to be supplied by the sector, characterized in that said supply comprises a circuit for converting the line voltage into a DC voltage of suitable value, the components of which are arranged on a printed circuit board, a closed box which can be fixed to the wall to house said card, a mains connection cord one end of which is connected to said circuit on the board inside the box and whose l the other end is terminated by a power outlet, and a female connection base fixed on the power supply unit for the output of the DC voltage and in that the remote control unit comprises a connection cord terminated by a plug male connection for connection to the power supply unit.

Une taLle alimentation peut avoir son boîtier fixé au mur à la tête du lit tu'hôpital ou de chambre d'hotel) où une prise secteur est toujours disponible à proximité. Le boîtier de télécommande infrarouge n'utilise donc plus de piles et la présence d'un cordon et d'une fiche de connexion branchée sur un boîtier fermé dissuade les utilisateurs de l'emporter. A power supply can have its box fixed to the wall at the head of the hospital bed or hotel room) where a power outlet is always available nearby. The infrared remote control unit therefore no longer uses batteries and the presence of a cord and a plug connected to a closed unit dissuades users from carrying it.

L'invention sera mieux comprise et d'autres carac téristiques apparaîtront à l'aide de la description ci-apres et des dessins joints où - la figure 1 représente l'ensemble selon l'invention , et - la figure 2 représente un schéma possible de circuit d'ali
mentation.
The invention will be better understood and other characteristics will appear with the aid of the description below and of the attached drawings in which - FIG. 1 represents the assembly according to the invention, and - FIG. 2 represents a possible diagram ali circuit
mentation.

Sur la figure 1 est représenté un boîtier 1 de télécommande infrarouge qui est muni selon l'invention d'un cordon de raccordement 6 à une alimentation. Ce cordon se termine par une fiche de connexion mâle 7. L'alimentation autonome est disposée dans un boitier 2 fermé fixé au mur. Ce boîtier abrite une carte de circuit imprimé portant les composants d'un circuit de conversion de la tension secteur en une tension continue de valeur convenable pour l'alimentation des circuits du boitier de télécommande. La tension secteur est amenée à ce circuit de conversion par un cordon 3 terminé par une prise secteur classique 4. En outre, le boîtier 2 comporte une embase châssis de connexion femelle fixée sur une de ses parois pour la sortie de la tension continue.  In Figure 1 is shown an infrared remote control unit 1 which is provided according to the invention with a connection cord 6 to a power supply. This cord ends with a male connection plug 7. The autonomous power supply is placed in a closed box 2 fixed to the wall. This box houses a printed circuit board carrying the components of a circuit for converting the mains voltage into a DC voltage of suitable value for supplying the circuits of the remote control unit. The mains voltage is brought to this conversion circuit by a cord 3 terminated by a conventional mains socket 4. In addition, the housing 2 comprises a female connection chassis base fixed on one of its walls for the output of the DC voltage.

Cette embase est adaptée pour recevoir la fiche male 7.This base is adapted to receive the male plug 7.

Comme on l'a déjà mentionne, le fait pour un utilisateur moyen d'avoir en main un boitier de télécommande avec un cordon de raccordement 6 et une fiche de connexion 7, qui le font douter a priori qu'un tel ensemble soit adaptable sans problème à un téléviseur de type grand public, -le dissuade dans la très grande majorité des cas d'emporter un tel boîtier. Par ailleurs, il n'existe plus de piles à changer périodiquement ou pouvant être dérobées. As already mentioned, the fact for an average user to have in hand a remote control unit with a connection cord 6 and a connection plug 7, which make him doubt a priori that such an assembly is adaptable without problem with a television of the general public type, -discourages it in the vast majority of cases from carrying such a box. In addition, there are no longer any batteries to be changed periodically or that can be stolen.

La figure 2 représente le schéma électrique d'un circuit d'alimentation dont les composants sont disposés dans le boîtier 2. Ce circuit comprend un transformateur 20 dont le primaire reçoit la tension secteur par l'intermédiaire du cordon de raccordement 3. Une extrémité du secondaire est reliée à la masse et l'autre à une diode 21 suivie d'un étage de filtrage comprenant les condensateurs 22 et 23 et la résistance 24. Une diode Zener 25 fixe le niveau de tension continue, par exemple 9 V, envoyé sur l'embase de connexion femelle 5. FIG. 2 represents the electrical diagram of a supply circuit whose components are arranged in the housing 2. This circuit comprises a transformer 20 whose primary receives the mains voltage via the connection cord 3. One end of the secondary is connected to ground and the other to a diode 21 followed by a filtering stage comprising the capacitors 22 and 23 and the resistor 24. A Zener diode 25 fixes the DC voltage level, for example 9 V, sent to the female connection base 5.

Bien entendu, l'exemple de réalisation décrit n'est nullement limitatif de l'invention.  Of course, the embodiment described is in no way limitative of the invention.
