Abstract
A lock and key combination wherein at least one locking tumbler includes a key sensing portion, a body portion and a locking portion. A cavity, accommodating an associated locking tumbler, is larger than the contour of the body portion so as to permit a translatory as well as a rotary movement of the locking tumbler in a movement plane within the cavity. A code pattern on the key blade includes at least one wave-like guiding surface. When the key blade is inserted into the key slot, the locking tumbler is controlled by two mutually spaced formations, which engage with the wave-like guiding surface of the key blade, and is guided at opposite side surfaces by two associates walls of the cavity, to be retained precisely in the movement plane. The locking portion of the locking tumbler is movable to enable the locking mechanism to be released.
