Disclosed is a lock and a key where the lock has at least one locking cylinder lock (1) rotatably mounted in its casing (2), and being provided at its inner end with an outer radial groove (10) with a securing member placed therein for axial securing the position of the cylinder lock (1) in the lock casing (2) body wherein a flat key (7) shaft (4) intended for the control of the lock is provided on its one edge with cutouts for bearing and adjusting lock key guards while on its opposite back side it is provided with at least one shaped cutout. In the region between the outer radial groove (10) and face of the cylinder lock (1) the cylinder lock (1) is provided with another radial groove (9) for inserting therein a ring-shaped segment of a stop member (3) secured in its position by at least one bent end, which is fastened in the cylinder lock (1) body. The stop member (3) cooperates with the lock key (7), the flat shaft (4) of which has on its opposite back side an upward open notch with a stop surface (11) arranged substantially perpendicular relative to longitudinal axis of the key (7) and formed by the rear side of the notch wherein the front side of the shaped notch opens obliquely in the direction towards the tip of the key (7) shaft (4) and wherein in functional position of the inserted key (7) the stop surface (11) of the key (7) shaft (4) bears on the stop member (3) in order to secure a required position of a closure on the key (7) bottom side counter the key guards and the lock locking pins, whereby the lock casing (2) is provided opposite to the stop member with a recess (14) the shape and depth of which correspond to the shape and thickness of the stop member (3) ring-shaped segment. |
