Easy-to-install prefabricated lock Lock (2) type consists of case (3) attached to fastening surface. Latch (4) moves against case (3) and is guided by case (3): latch (4) is connected functionally to respective operating lever systems (5) controlled by actuator. Prefabricated lock (1) includes shaped plate (7) with a device (8) for connection to respective fastening surface and with selective fastening elements (9) for case (3). Case (3) includes elastic sections (10) for catching, with at least some fastening elements (9) removable in installation configuration. |

Lock for installation in thin wall opening Lock comprises a head part placed onto the external side of the thin wall and covering the external edge of the hole; a body outgoing from the head part and passing through the hole in the set position; fastening elements outgoing from the body and able of bending in direction of its external surface. The free end of the specified fastening elements is equipped with an inclined surface to create a support for the body at the edge or border of the hole without slackness of the other, internal side of the thin wall. The body and the retention element are two separate parts. |

Present invention pertains to architectural hardware and relates to a locking device, which has a lock and a corresponding member for coupling, locking the turning door, hatch etc. The lock comprises a first locking element, with a first free end, and which, in the set position, lies crosswise relative the axis of rotation of the turning part. The corresponding member comprises a second locking element, with a second free end, and which, in the set position, lies crosswise relative the axis of rotation of the turning part. The locking elements are arranged for combined operation, such that, when the elements are opposite each other in their set position, when the door, hatch etc. is closed, they overlap. The device also has a working member, with a lever, the first end of which comprises an articulated apparatus. The lever has a clevis. The working member is fixed to the body of the lock by the articulated apparatus, through which the lever can rotate about a turning point, formed by the articulated apparatus. This device has high resistance to break-in. |

Cylinder mechanism of deadlock The cylinder mechanism of the deadlock has a body, in which drums with cores and a key are installed on both sides. The body length is made permanent and less than the minimum thickness of the entrance doors, and the length of the key depends on the thickness of the entrance door. The bosses of the inserts are installed in the holes of the cover plates, round holes for the key are made in them coaxially with the axis of the mechanism cores. Segment lugs are made on the end faces of the cores, their plane surfaces are engaged with the end sections of the plane bottom of the groove made on the stepped section of the key at its rotation. |

Lock comprises body with side surface, base and connection means to attach thereof to supporting surface, as well as secrecy mechanism, cross-bar cooperating with secrecy mechanism and performing authorized movement. Connection means is made as bracket with orifices and as connection members having fixing means and coupling means. One part of the bracket is attached to side wall of the body, another part thereof is arranged from the side of another body part and spaced a distance equal to h from above body part. Above bracket part defines a cavity. Connection members are located in bracket orifices and fixing means are arranged in the cavity. |

The invention is pertaining to the field of production of ironmongery, in particular, to production of a strike plate containing a metal plate, on which there is a rectangular form window and a hole for the strike plate fastening on a stationary framework, which at the locking bar pushed forward into "closed" position, is covered by the locking bar. At that there is the second hole for the strike plate fixation on a stationary framework located so, that at the locking bar pushed forward into "closed" position access to fastening holes of the strike plate is overlapped. These holes are located horizontally. The given strike plate ensures the heightened resistibility against the doorpost locking systems breaking. |

Door locking system production method and door locking system Method involves producing at least two locks; providing locking system with hinges and pivotally securing locks one to another; connecting hinges to lock bodies. Lock production process includes forming body, cross-bar and securing mechanism; arranging securing mechanism in body; communicating cross-bar with securing mechanism; producing locking member or locking members and arranging at least one cross-bar so that cross bar may cooperate with locking member. One lock or body thereof is made as three-dimensional structure of arbitrary geometrical shape in plane and in cross-section intersecting three-dimensional through cavity. Another lock or body thereof is made as three-dimensional structure of arbitrary shape in plane and in cross-section and at least partly arranged in three-dimensional cavity. Locking member for cross-bar of one lock is made in another lock or body thereof. Locking system is also disclosed. |
