the first diebstahlsicherungsvorrichtung and trying on jewelry

摘要

The device has an integration unit provided for each of a set of rings (1). Each integration unit integrates a reception head to each ring and extends a movable cylinder (3) that slides through one of the openings (7), where the course of the cylinder is limited in a safety position by a stop (6) that is placed on a plate (4). The cylinder has a lateral surface comprising a machined gorge whose angular extension permits the rotation of the ring that is fixed on the reception head of the cylinder. The gorge has an inverse V shape and the angular extension is smaller than an end of the gorge. An independent claim is also included for a jewelry display case comprising a display plate having a jewelry display and demonstration device.
