Lock mechanism with a key removal interlock and an interlock of key removal from a lock mechanism

摘要

A lock mechanism has a key removal interlock. The interlock enables removal of the key from the lock in only one angular position. The lock mechanism includes a cylinder (1) which includes an inner sleeve (2) and an outer sleeve (3). The locking components (5) are radially arranged angularly in rows (4) along the axis of the cylinder and are radially movably positioned in channels (6) that extend in the inner sleeve and the outer sleeve. A cylindrical key with decoding elements on an outer surface is usable to unlock the lock mechanism. In one arrangement a plurality of locking components are positioned in the inner sleeve and outer sleeve with different angular spacing between the channels so as to only allow key removal in one angular position. In another arrangement, a plurality of rows of locking components has one row with a number of channels that is different than in the remaining rows so as to only allow key removal in one angular position.
