Door locking device

Abstract

A device for locking movable partitions that restricts the access to confined areas, having a key, lock and a handle, provided with a latching/release mechanism and a bolting mechanism, characterised in that the key (1) has a flat shape and is provided with a set of movable, concentrically-arranged, closed rings in the form of: an outer ring (2), a central ring (3) and an inner ring (4) integrated with a central disc (5), wherein each one of the rings (2, 3, 4) is provided with at least three, semi-spherically shaped decoders (6), while the central disc (5) has a centrally-located stabilising through hole (7) that has at least two angled corners (8), wherein lock (9) consists of a movable press (10) and a rotary positioner (12) connected with the bolting mechanism (11), wherein the movable press (10) is provided with a centrally-located wedge element (13), the base (14) of which has a shape that corresponds to the shape of the stabilising hole (7) of key (1), while the rotary positioner (12) is provided with a centrally-located wedge channel (15) that enables the installation of wedge element (13) of movable press (10) therein, simultaneously the flat surface (16) of the rotary positioner (12) has elastic studs (17), wherein between the movable press (10) and the rotary positioner (12) there is a pressure gap (18) that acts as the termination of input tunnel (20), wherein the input tunnel (19) and the output tunnel (20) act as keyways for the movement of key (1), wherein the input tunnel (19) begins with feeder (22), while the output tunnel (20) ends with receiver (23), wherein the feeder (22) and the receiver (23) constitute flat openings installed on door (21) that enable the insertion and removal, respectively, of key (1), wherein the minimum width (W18) of pressure gap (18) represents at least the width (W1) of key (1).
