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.

A safety lock having a latch bolt and at least one key-operated bolt both movable to an unlocking position by turning of a single key. Combination tumbler plates are located on opposite sides of an operating plate connected to the key-operated bolt. The tumbler plates are constructed to be moved to a releasing position, permitting movement of the operating plate, regardless whether the key is inserted from one or the other side of a box in which the elements of the lock are mounted. The key-operated bolt is moved to the unlocking position during turning of the key in one direction and means are provided to move the latch bolt to its unlocking position during further turning of the key in the one direction without further withdrawing the key-operated bolt.

A cylinder lock, especially suitable for motor vehicle doors, has a locking cylinder and a key, whereby the locking cylinder includes at least one cylinder housing with at least one blocking channel and one cylinder core with tumblers, each of which is movable about its own axis. At least one protruding cam or a recess is provided on the key or on the tumblers for transmitting the linear key motion in the key channel into a motion of each tumbler about its own axis.

This bolt lock is for a sliding patio door. Primarily, it consists of a housing containing a lock mechanism for the outward and inward travel of a pair of toothed lock bolts, which are slideably received between a pair of side frames of said housing. It also includes a sector gear and a small gear, which serve to advance and retract said pair of toothed lock bolts, simultaneously, when the lock cylinder of the combination is turned by a key.

The present invention proposes a lock with combination pins of non-circular section and eccentricity capable of being positioned in rotation, according to which the seatings or housing orifices for the pin-counterpin sets are aligned. At least one of these same orifices in the rotor two semi-pins are housed together, abutting each other and being provided with respective eccentric tips. The eccentric tips of the pair of semi-pins housed in a same orifice are capable of operating in combination indentations belonging to a same or to two different rows of cuts provided in the shaft of the key. The semi-pins of which have paraxial projections, which are reciprocal with corners formed in the transversal section of the orifice corresponding to the seating. Each semi-pin has a counterpin associated with it, which is mounted against a spring.
