Closing latch modular mechanism includes a mechanism casing, a latch with a bevelled surface and a longitudinal surface parallel to the plane of the door, a support, a rotation shaft, an anti-rotation device, a rotatory lever carrying the anti-rotation device, a carriage that is longitudinally displaceable parallel to the plane of the door and a mechanism for actuating the carriage. The latch (2) is installed in the support by the rotation shaft and has a receptacle of semicircular cross-section elongated tangentially at its ends. The receptacle is parallel to the rotation shaft and is situated in its rear surface at a distance from the plane of the door that is suitably greater than the distance of the rotation shaft, and in opposition to the rotation shaft (4).

A code changing mechanism for padlocks of the type comprising code wheels and lock operating bushings releasably connected to the code wheels in which axial movement of the shaft disengages the bushings from the code wheels to permit changing of the code, and in which the long leg of the shackle has means for engaging the end of the shaft to move it axially to the disengaging position when the shackle is depressed into the body in an orientation other than the locking orientation. In one embodiment of the invention the shackle can be locked in the open position to prevent code changing without knowledge of the existing code.

Improvements for an engaging mechanism for locks, wherein a spindle (6b) of the radial actuator (6) has an articulated connection to the tip of a first elastic arm (13), which elastic arm is radially fixed at its other end in an axis (14) that is mounted with freedom to turn, and that one end of a second elastic arm (15) is radially fixed in this axis (14) with a 90° difference in rotation, the second elastic arm having its other end meshing with the spiral thread of an endless screw (16), which forms the output axis of an electric motor (17) that turns in both directions of rotation and is oriented transversely to said freely rotating axis (14).

The key of the key and lock system has a blade with at least two zones of different thickness, a nominal thickness zone and a reduced thickness zone. The reduced thickness zone has a displaceable element having a length which exceeds the thickness of the reduced thickness zone and is less than or equal to the nominal thickness zone. The slot of the lock has a recessed longitudinal profile where the size of the recesses is equal to the excess dimension of the displaceable element. At least one radial pivot is diametrically aligned with a security pin in the slot. The radial pivot protrudes inside the slot by an amount equal to the excess dimension of the displaceable element. When the key is fully inserted inside the slot, the displaceable element is situated between the radial pivot and the security pin and allows the lock to open.

A safety closure for controlled access, that includes an inner and outer unit mounted on a door to drive a main bolt and a privacy bolt. The outer unit has an armored chassis with a primary tube of the actuating handle and carrying a secondary tube having a square axis that drives the main latch. A retractable tenon provides the connection between the primary and secondary tubes and a retractor treadle is in permanent contact with the retractable tenon and a rocker having elastic arms that drives the retractor treadle. A motorize actuator is activated by an electronic card reader. The motorized actuator or an emergency handle may actuate the rocker in opposite directions. The inner tube has first and second pushing tabs symmetrically arranged in mutual opposition whereby the pushing tabs act independently of each other in response to the direct or opposite turning of the inner actuating handle to actuate the privacy bolt. An emergency lock cylinder drives the emergency handle.

The present invention relates to a lock which features projections located in a single plane of the rotor and stator lined into two opposing rows. The drillings for the main group of projections and their corresponding springs extend through the rotor to the opposite side of the frame or stator but not through it completely. This blind drilling forms the exact lodging for an antagonistic second set of projections and springs.

A programmable electronic access control system with “on line” updating without cables has at least one communication centre or node, which is connected to the central control unit via a standard industrial communication network, and includes transceiver means which are used to wirelessly connect, via radio-frequency channels, each communication centre to at least one access element in which the user presents the access certificate.
摘要:
Security device for lock cylinders, which consist of a rotor (1) which rotates in the cavity of a stator (2), which locks use true keys (4) in which the combination for opening is by means of peaks and valleys of different sizes which operate in conjunction with respective pairs of pins (5-6), which, when accommodated in the key opening position, consist of a rotor pin (5) and a stator pin (6) which is loaded by a spring (7); the rotor (1) incorporates the channel (8) for insertion of the true key (4) in which there is provided a usual virtual line (9) according to which there is longitudinal alignment of the tips of the rotor pins (5), in the state in which the key is not inserted; characterised in that at least one of the rotor pins (5), which shall be known as the security pin (10), has some end means which prevent the remainder from reaching the usual virtual line (9) in the state in which the key is not inserted or the lock is empty, and its advance reaches only a virtual security line (9B) which is shorter than that of the usual virtual line (9).
