摘要

Safety device for universal intended to simplify, advantage of the current internal mechanisms of mecu2030nicas locks.The present invention relates to a safety device whose internal mechanism simple consists of two plates (11) adjacent, rectangular, equal and also perforated.Interconnected by positioning pins (12) that keeps them apart and parallel.Between the plates of the mechanism and constrained by the layout, shape and size of its perforations (13 and 15) funcionan their movable parts, formed by bending springs (16).Safety lock (18) and balls (21), these spheres, driven to the central region of the mechanism under the effect of the springs (16).At the same time, accommodate the depressions (29) existing in the edges of the key (Fig. 4) when, due to its configuration, pointed, penetrates into the mechanism of the spheres.So they created the conditions for the operation of the devices of security, because in this position the perforations (19) of the security locks are positioned with the perforations (14) of the plates.Which allows the recoil of the grains and, consequently, the collection of the tab on the device.
