Abstract

Lock with articulated safety key, characterized in that it essentially comprises the assembly constituted by a conventional type lock with an entrance hole adapted to the key which consists of a maneuvering end integral with a strong shaft at the end of which a part capable of taking two positions substantially at 90 [deg.] from one another is articulated, said positions being controlled by a control element whose end opens for manipulation at the main maneuvering end of the key a with the particularity that, for one of the two positions: of: the articulated piece, the latter being placed against the corresponding end part of the shaft referred to above so that the cross section of the boom and of the said piece refuted against the latter determines taking into account a small clearance, the configuration of the hole for the passage of the key provided with the lock, while the to its other position, said articulated piece is deployed and sensibly at 90º with respect to the same shaft, corresponding to the active moment after the previous insertion of the key retracted by the hole of the lock previously alluded to so that said articulated piece unfolded, with its corresponding toothed configuration of the lock type is capable of acting inside the lock in the conventional manner, and then, prior to being retracted, the key can be extracted from its housing.
