This invention relates to a security device for removably locking two mobile elements together, for example a door and the frame on which it is mounted. In particular, the device is in the form of a lock, and is intended for fixing to one of the elements, for example a door, and includes an engagement member such as a bolt, able to move from an engagement position to a disengagement position and vice versa, control means, for example a key for the engagement member, and one or more elements for transmitting the operation of the control means to the engagement member. Each transmission element comprises two or more sectors able to move towards and away from the respective transmission element. Each sector cooperates with a sliding rocker element able to interact with the engagement member and be controlled sequentially by the control means by way of one or more transmission elements, to allow movement of the engagement member.
In a security device for removably locking two mobile elements together, the device being designed to be fixed to one of the two mobile elements and having a bolt member arranged to be displaced from a locked to an unlocked position and vice versa, at least two actuation keys which differ from one another, control means for allowing the bolt member to be displaced by the actuation keys, and at least one transmission element arranged to operate the control means and to be actuated by either actuation key, the improvement wherein for each transmission element the control means comprises a pair of first and second engagement members movably mounted on respective supports provided on a common adjustable carrier, and a respective matching element for the first and the second engagement member, whereby each one of the actuation keys can cause either the first or the second engagement member or members to match with its respective matching element, thereby allowing the bolt member to be displaced.
