Antitheft device for spectacles

Abstract

Abstract The device is mounted on a side piece of the spectacles and consists of a bush designed to be threaded over the side piece so as to lock the spectacles in an open position. The bush has an extension which bears on the rear surface either of the lens or of the frame. Means for locking the device are provided so as to prevent the bush from moving with respect to the side piece on which it is mounted, and so that the extension prevents the said side piece from being folded away. The device includes a housing (2), shaped more or less like a flattened parallelepiped. An identification unit, sealed inside the housing, is capable of being detected in a detection system using high or low frequency electromagnetic radiation combined with a visual and/or audible alarm. The housing has, on one of its main surfaces (14), means (15, 16) for holding the bush (1). These means are so arranged that they prevent any separation of the bush (1) and the housing (2) before the mechanism (6) locking the bush with respect to the side piece (8) on which it is mounted has been released. <IMAGE>
