Method of unlocking involves a lock consisting of bar with prop anchor, lever tumblers and key with bit, where the key engages lever tumblers and brings them from original position to operational position matching the lock code, which allows prop anchor of the bar to go through respective passes in lever tumblers. Further, lever tumblers are fixated in the set operational position, and an effort is exerted on the bar via the key to shift the bar. Lever tumblers are brought and fixated in operational position in definite angle sector of key turn with mechanical blocking on bar movement, and the bar is unblocked and shifted in another angle sector with forced fixation of lever tumblers movement against each other. |

Method to lock and unlock lock and lock for its realisation (versions) By rotating a key, a control bushing is rotated, and when the key is turned by the angle sufficient to put code level tumblers into the working position, the control level tumblers are moved by rotation of the control bushing, unlocking the fixator of the level tumblers, which is moved into the fixing teeth of the code level tumblers, and the possibility of their movement is blocked. In the body there is also an additional mechanism for synchronisation of lock parts operation and locking of a bolt, which comprises a fixator of code level tumblers, a stop, at least one control level tumbler and a control bushing, which is installed as capable of rotation relative to the axis of the key in slots of the front and rear walls of the body with a slot for placement of the key, with a driving tooth and figured cams. |

Wing-key lock for wooden and metal doors comprises body with keyhole displaced relative to longitudinal axis of lock in direction of one of its lateral sides, face plank and cover with its keyhole displaced from longitudinal axis of lock towards opposite side by the same value. Besides between body and cover there is a set of movable spring-loaded wing-keys installed on guide columns, on plane of which there are various versions of locking windows, and at least pair of fixed plates with cuts for keys arranged opposite to keyholes coaxially with them, and between plates there is a bolt that moves in direction of longitudinal axis of lock and has locking columns, for which there are guide slots arranged on plane of fixed plates as parallel to longitudinal axis of lock. Body and cover of lock are arranged in the form of identical half-bodies with individual configuration of keyhole for each of them. |

Method for lock unlocking and lock that realises this method Method for unlocking of lock consists in the fact that changing levels from initial position into working one, which complies with the lock code, ends with fixation of levels in specified working position, at the same time changing levels into working position and fixation of levels in this position is executed in a certain angular sector of key turn under conditions of mechanical blocking of latch motion, and latch unlocking and its displacement is carried out in another angle sector of key rotation, where access to levels is closed. To execute these operations, locks comprises mechanisms of displacement and mechanical blocking of latch and installation of levels into initial position, and also protective screen that closes access to levels from outside in certain angle sectors of key rotation. |

Invention refers to a group of safety locks with two-bit key meant for dwelling doors, etc. Lock consists of two-bit key locking mechanism with many plate-like key bits activated after profiled outlines of two flag-shaped protrusions provided on key body touch them. Lock also includes cylindrical locking mechanism with possibility of cylinder turning around axis coinciding with key turning axis provided in two-bit key locking mechanism. Locking mechanism with cylinder being turned is designed for being brought into operation with the above lock together with bringing of two-bit key locking mechanism into operation. |

Secret block of for bit-key lock Secret block contains side plates of a bar with hollows for interaction with the bits of a key and a hole for the locking poll and placed between them on the guiding polls a set of flexible half-bit-keys with an individual code perforation, a hole for interaction with the bits of a key and locking tabs for interaction with the locking poll. The locking tabs are arranged at the opposite peripheral edges of each half-bit-key, code perforations and holes for interaction with the bits of a key are situated in the window of the central part of half-bit-keys. The gutters for the guiding polls are situated diagonally in the angles of the half-bit-keys field. The set of half-bit-keys is sprung by the general flat spring of a spring type which ends rest on its own half-set of half-bit-keys. At the side plates of the bar there is an additional hole for the second locking poll and above it there is rectangular hole for the flat spring. Holes for the interaction with the bits of a key are made in the middle part of the side plates and are connected with the respective holes and code perforations of the half-bit-keys. The half-bit-keys in the set are arranged one on another with the reverse side with the turn around their both vertical and horizontal axes. |

Secrecy block for four-turn slide-type locks Secrecy block includes bolt sides with depressions to cooperate with key bits and with slot for locking post receiving, as well as a set of semi-slides arranged in-between and supported by guiding posts. The semi-slides may move under the action of key and are spring-loaded by compression springs. The semi-slides have surfaces provided with slots for compression spring and guiding posts receiving. Block also has locking window with projections to cooperate with locking post, code combination to provide cooperation of half of semi-slides associated with key bits and notching to prevent another semi-slides half cooperation with the first one. Slots for compression spring receiving are identical with each other and have centers located in diagonal line of each semi-slide. Centers of guiding post receiving slots lie in another diagonal line. Locking window is made in transversal axis of semi-slide between different slot pairs. Locking extensions adapted to cooperate with locking post are created in one half of locking window passing into slot for locking post receiving at another window half. Code combination to cooperate with key bits is created in peripheral semi-slide edge under locking projections of locking window. Notching is created on opposite peripheral edge thereof and extends along diagonal line over locking post receiving slot. Said notching prevents contact of corresponding semi-slides with key bits from opposite secrecy block side, wherein each next semi-slide of the set is laid on previous one by the same side and turned through 180° in plane thereof. |

Method for key-operated slide-type lock production and bit-key lock Slide-type lock has body with cavity, spring-loaded slides with guiding orifices, figured orifices provided with secrecy extensions and depressions formed in orifice edges. Slide blocking means arranged in body interior may cooperate with lock key. Slide blocking means is made as slots formed in spring-loaded slides, spring-loaded blocking slider with rest, guiding orifices, figured orifice provided with secrecy extensions and depressions formed in orifice edges and rotary spring-loaded latch. The latch is axle-mounted so that latch may cooperate with spring-loaded blocking slide. Spring-loaded blocking slide is also mounted on guiding means by means of guiding orifices so that slide may be displaced to cooperate with lock key bit. The slots are arranged in front of rest and may cooperate with rest when unauthorized influence is applied to spring-loaded slides. |
