LOCK WITH MULTI-MOVABLE CODE ELEMENTS Russian patent published in 2016 - IPC E05B1/00 

FIELD: construction.

SUBSTANCE: invention relates to key locks: cylinder, disc, pin, etc. In transverse working channel (8) of cylinder mechanism core (2) there are three elongated drivers (12, 13, 36) and pair of toothed sectors (10, 38) with possibility of translational and rotary-and-forth motion respectively. Drivers (12, 13, 36) interact with control grooves of flat key introduced into core (2) keyhole (6) by reading cams. Toothed sector (10) performs code element function and equipped with off-round code hole (23), adjustable connected with driver (12) by means of axis (32) and coupled with driver rack bar (13) by teeth (14). Toothed sector (38) is designed to control clamp (20) turning, adjacent by plane to gear sector (10), engaged with driver rack bar (36) by teeth (37) and is mounted loosely with its central hole (39) on retainer (20) made elongated; latter is located in radial channel (18) released in channel (8), with possibility of first and second motions respectively, progressive motion and rotation in channel (18). Retainer (20) can also be installed, besides, rotary, on locking arm. Retainer (20) and central hole (39) meet code hole (23) by cross section. Introduced into keyhole (6) key draws drivers (12, 13, 36), and they draw code element (10) and toothed sector (38). Code element (10) performs turn-and-forth movement in directions (V1), and retainer (20), drawn by toothed sector (38) performs second movement: turning in direction (V2). If key is "right", retainer (20) and code hole (23) are in alignment to each other on three parameters, in longitudinal and transverse directions, as well as in turn, thereby retainer (20) acquires possibility of first movement inside core (2) and thus unblocks it.

EFFECT: increase of total stroke code of code element surface in all its possible motions relative to retainer having possibility of reading code element position and control over blocking of locking mechanism.
