Patent

CA 2179796

A device used in a multimedia communication system is formed with a transceiver unit for transmitting and receiving information signal to and from the inside of a room and a base unit adapted to be mounted to a wall of the room to detachably support the transceiver unit. The transceiver unit has a plug surface on which a plug projects, a circular wall projecting on the plug surface to surround the plug, and a guide wall projecting on the plug surface inside the circular wall and around the plug. The base unit comprises a disk member which is provided with a receptacle exposed in a receptacle surface defined on the disk member. The disk member has a diameter slightly smaller than an inner diameter of the circular wall so that the disk member can fit within the circular wall when the transceiver unit is attached to the base. The disk member is formed in the receptacle surface with a guide groove of such a configuration that the guide wall is allowed to be inserted into the guide groove only when the guide wall opposes to the guide groove at a particular angular orientation where the plug comes to be connectable with the receptacle. The device can provide a safe and easy working condition for attaching the transceiver unit to the base unit.

ispositif utilisé dans un système de communication multimédia et comprenant un émetteur-récepteur pour l'échange d'informations entre une pièce et l'extérieur, et un support mural pour l'accrochage et le décrochage de l'émetteur-récepteur. Celui-ci comporte une surface-fiche dont dépassent la fiche, une paroi circulaire entourant la fiche, et une paroi-guide aménagée à l'intérieur de la paroi circulaire, autour de la fiche. Le support comprend une partie en forme de disque sur laquelle est définie une surface-prise. La partie en forme de disque a un diamètre légèrement inférieur au diamètre intérieur de la paroi circulaire de sorte qu'elle peut s'y insérer lorsque l'émetteur-récepteur est fixé au support. Dans la surface-prise, une rainure-guide est dessinée de telle façon que la paroi-guide peut s'y insérer seulement sous un angle d'enfichage particulier. Le dispositif permet la raccordement sécuritaire et facile de l'émetteur-récepteur support.
