Abstract
The invention relates to locking devices of enhanced security. primarily locks for locking dead bolt systems of safes, metal doors of residential buildings, public and other buildings and offices, as well as to padlocks, etc., where a high level of resistance to breaking is required.
Claims3
A blocking lock with a matrix coding system comprising:
- a housing containing a narrow slot for a plate-like key,
- a movable locking plate,
- a plurality of balls which overlap the slot for the plate-like key, and
- a plurality of ball openings, the plurality of ball openings located on a key mortise plate having a depth not greater than a radius of the plurality of balls,
- wherein the key mortise plate is rigidly fastened to the movable locking plate, and the housing contains a stationary matrix provided with code element openings,
- wherein the code element openings are drilled in the matrix coaxially with the locking plate in a maximum locked position, and provided with the ball openings, a short pin, a long pin, and a code spring disposed therein;
- wherein in the housing, there is formed a rotating protrusion for guiding the key to an area of the key mortise plate having a recess for the balls;
- wherein the housing comprises a working spring to interact with the housing and the locking plate;
- wherein the locking plate and the matrix are provided with synchronization system openings designed for synchronizing operation of the blocking lock, which synchronization system also includes a locking ball, a push pin, and a spring of the synchronization system, the housing is closed with a cover to fix the matrix and compress the code springs and the synchronization system spring;
- and
- wherein the narrow slot has a curved shape formed by the radii of the rotating protrusion, the locking plate, and the matrix.
