Lock arrangement

A lock arrangement which includes a lock casing (5), a key-operated cylinder lock (1) mounted on one side of the casing, and a knob or finger-turn mechanism (7-10) mounted on the other side of the casing, said knob or finger-turn mechanism being effective in activating a lock-mechanism activator device, such as a follower (6) located in the lock casing (5), through the intermediary of a cylinder-lock dogging element (4) and a knob dogging element (8), characterized in that the cylinder-lock dogging element (4) and the knob dogging element (8) are axially movable and are in end-to-end connection with one another at least in given positions of axial movement;

• and in that the knob dogging element (8) is intended to be located, depending on whether said knob dogging element is rotated to a position corresponding to the locked mode or the unlocked mode of said lock mechanism, in either a withdrawn position or an outwardly projected position in which the knob dogging element is held against axial movement and in which the cylinder-lock dogging element (4) will prevent a standard key (1) which fits the cylinder lock (3) from being inserted fully into said cylinder lock.
