<p>Door lock and key, the door lock having at least one sleeve cylinder (1) which can rotate within its body (2) and its inner end has an outer radial groove (10) with a Seger ring left to be axially fixed the disposition of the sleeve cylinder (1) in the body of the door lock. The nib (4) of the flat key (7) to be used with this door lock has groovings for adjusting to the pins of the door lock andat least one shaped incision on the opposite edge. In the region between the outer radial groove (10) and the front of the sleeve cylinder (1) the latter has another radial groove (9) for placing a ring shaped segment of the stopping element (3) fixed at its position by at least one bent end installed in the sleeve cylinder (1). The stopping element (3) interacts with the key (7) for the door lock whose flat nib (4) (on the opposite edge) has an open upside incision with a practically perpendicular stopping surface (11) positioned along the longitudinal axis of the key (7) and shaped by the back side of the incision, where the front side of the thus shaped incision opens towards the tip of the nib (4) of the key (7). At the position of functioning with an inserted key (7) the stopping surface (11) of the nib (4) of the key (7) is posited opposite to stopping element (3) for achieving the needed position of the code elements of the lower part of the key (7) against the locking studs ofthe door lock. Opposite to the stopping element (3) the door lock body is supplied with a groove (14) whose shape and depth correspond to the shape and width of the ring shaped segment of the stopping element (3). The flat nib (4) of the key (7) to be applied to this door lock has groovings for adjusting the studs of the door lock to one of its edges and the edge of the inverse side has an upwardly opened incision with practically perpendicular stopping surface (11) positioned along the longitudinal axis of the key (7).</p> |
